Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. Fees and expenses of the Private Fund (as defined herein), a wholly-owned subsidiary of the Fund, are included in the table.

You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in the Invesco Funds. More information about these and other discounts is available from your financial professional and in the section “Shareholder Account Information – Initial Sales Charges (Class A Shares Only)” on page A-3 of the prospectus and the section “Purchase, Redemption and Pricing of Shares-Purchase and Redemption of Shares” on page L-1 of the statement of additional information (SAI). The table and Examples below do not reflect any transaction fees that may be charged by financial intermediaries, or commissions that a shareholder may be required to pay directly to its financial intermediary when buying or selling Class Y or Class R6 shares.

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

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

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

	1 Year	3 Years	5 Years	10 Years
Class A	667$	916$	1,183$	1,946$

Class C	300$	618$	1,062$	2,102$

Class R	150$	465$	803$	1,757$

Class Y	99$	309$	536$	1,190$

Class R5	91$	284$	493$	1,096$

Class R6	84$	262$	455$	1,014$

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

	1 Year	3 Years	5 Years	10 Years
Class A	667$	916$	1,183$	1,946$

Class C	200$	618$	1,062$	2,102$

Class R	150$	465$	803$	1,757$

Class Y	99$	309$	536$	1,190$

Class R5	91$	284$	493$	1,096$

Class R6	84$	262$	455$	1,014$

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 30% of the average value of its portfolio.

Principal Investment Strategies of the Fund

The Fund mainly invests in common stocks of issuers in developing and emerging markets throughout the world and at times it may invest up to 100% of its total assets in foreign securities. Under normal market conditions, the Fund will invest at least 80% of its net assets, plus borrowings for investment purposes, in equity securities of issuers whose principal activities are in a developing market, i.e. are in a developing market or are economically tied to a developing market country, and in derivatives and other instruments that have economic characteristics similar to such securities. The Fund will invest in at least three developing markets. The Fund focuses on companies with above-average earnings growth.

In general, countries may be considered developing or emerging markets if they are included in any one of the Morgan Stanley Capital International (MSCI) emerging markets indices, classified as a developing or emerging market, or classified under a similar or corresponding classification, by organizations such as the World Bank and the International Monetary Fund, or have economies, industries and stock markets with similar characteristics. For purposes of the Fund’s investments, a determination that an issuer is economically tied to a developing market country is based on factors including, but not limited to, geographic location of its primary trading markets, location of its assets, its domicile or its principal offices, or whether it receives revenues from a developing market. Such a determination can also be based, in whole or in part, on inclusion of an issuer or its securities in an index representative of developing or emerging markets.

The Fund may invest directly in certain eligible China A Shares through Stock Connect (a securities trading and clearing program designed to achieve mutual stock market access between the People’s Republic of China (PRC) and Hong Kong), or, for operational efficiency and regulatory considerations, through an investment in a private investment vehicle organized under Delaware law (the “Private Fund”). The Private Fund may invest in companies established or operating in, or with significant exposure to, the PRC or other developing markets countries. The Private Fund’s managing member, OppenheimerFunds, Inc., has full and exclusive discretionary authority to manage the day-to-day operations of the Private Fund and to invest its assets. The Fund’s investment in the Private Fund may vary based on the portfolio manager’s use of different types of investments that provide exposure to Chinese securities (through Stock Connect). Since the Fund may invest a portion of its assets in the Private Fund, the Fund may be considered to be investing indirectly in such securities through the Private Fund.

In selecting investments for the Fund, the portfolio manager evaluates investment opportunities on a company-by-company basis. This approach includes fundamental analysis of a company’s financial statements,

1 Invesco Developing Markets Fund

management record, and capital structure, operations, product development, and competitive position in its industry. The portfolio manager also looks for newer or established businesses that are entering into a growth cycle, have the potential for accelerating earnings growth or cash flow, and possess reasonable valuations. The portfolio manager considers the effect of worldwide trends on the growth of particular business sectors and looks for companies that may benefit from those trends and seeks a diverse mix of industries and countries to help reduce the risks of foreign investing, such as currency fluctuations and stock market volatility. The portfolio manager may invest in growth companies of different capitalization ranges in any developing market country. The portfolio manager monitors individual issuers for changes in the factors above, which may trigger a decision to sell a security.

As part of the Fund’s investment process to implement its investment strategy in pursuit of its investment objective, the Fund’s portfolio manager also considers both qualitative and quantitative environmental, social and governance (“ESG”) factors they believe to be material to understanding an issuer’s fundamentals, and assesses whether any ESG factors pose a material financial risk or opportunity to the issuer and determines whether such risks are appropriately reflected in the issuer’s valuation. This analysis may involve the use of third-party research as well as proprietary research. Consideration of ESG factors is just one component of the portfolio manager’s assessment of issuers eligible for investment and the Fund’s portfolio manager may still invest in securities of issuers that may be viewed as having a high ESG risk profile. The ESG factors considered by the Fund’s portfolio manager may change over time and one or more factors may not be relevant with respect to all issuers eligible for investment.

Principal Risks of Investing in the Fund

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

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.

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.

Risks of Foreign Investing. Foreign securities are subject to special risks. Securities traded in foreign markets may be less liquid and more volatile than those traded in U.S. markets. Foreign issuers are usually not subject to the same accounting and disclosure requirements that U.S. companies are subject to, which may make it difficult for the Fund to evaluate a foreign company’s operations or financial condition. A change in the value of a foreign currency against the U.S. dollar will result in a change in the U.S. dollar value of investments denominated in that foreign currency and in the value of any income or distributions the Fund may receive on those investments. The value of foreign investments may be affected by exchange control regulations, foreign taxes, higher transaction and other costs, delays in the settlement of transactions, changes in economic or monetary policy in the United States or abroad, expropriation or nationalization of a company’s assets, or other political and economic factors. In addition, due to the inter-relationship of global economies and financial markets, 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. Foreign securities may trade on weekends or other days when the Fund does not price its shares. As a result, the value of the Fund’s net assets may change on days when you will not be able to purchase or redeem the Fund’s shares. 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. Foreign securities and foreign currencies held in foreign banks and securities depositories may be subject to only limited or no regulatory oversight.

Risks of Developing and Emerging Markets. Investments in developing and emerging markets are subject to all the risks associated with foreign investing, however, these risks may be magnified in developing and emerging markets. Developing or emerging market countries may have less well developed securities markets and exchanges that may be substantially less liquid than those of more developed markets, and investments in such securities markets may be subject to unexpected market closures. Settlement procedures in developing or emerging markets may differ from those of more established securities markets, and settlement delays may result in the inability to invest assets or to dispose of portfolio securities in a timely manner. Securities prices in developing or emerging markets may be significantly more volatile than is the case in more developed nations of the world, and governments of developing or emerging market countries may also be more unstable than the governments of more developed countries. Such countries’ economies may be more dependent on relatively few industries or investors that may be highly vulnerable to local and global changes. Developing or emerging market countries also may be subject to social, political or economic instability. The value of developing or emerging market countries’ currencies may fluctuate more than the currencies of countries with more mature markets. Investments in developing or emerging market countries may be subject to greater risks of government restrictions, including confiscatory taxation, expropriation or nationalization of a company’s assets, restrictions on foreign ownership of local companies, restrictions on withdrawing assets from the country, protectionist measures, and practices such as share blocking. The ability to bring and enforce actions in developing and emerging market countries, or to obtain information needed to pursue or enforce such actions, may be limited. In addition, the ability of foreign entities to participate in privatization programs of certain developing or emerging market countries may be limited by local law. Other risks may include additional transaction costs and difficulty related to the quality, availability and timeliness of information. Investments in securities of issuers in developing or emerging market countries may be considered speculative. Companies in developing and emerging market

2 Invesco Developing Markets Fund

countries may also generally be subject to less stringent regulatory, disclosure, financial reporting, accounting, auditing and recordkeeping standards than companies in more developed countries. As a result, information, including financial information, about such companies may be less available and reliable which can impede the Fund’s ability to evaluate such companies.

Geographic Focus Risk. The Fund may from time to time have a substantial amount of its assets invested in securities of issuers located in a single country or a limited number of countries. Adverse economic, political or social conditions in those countries may therefore have a significant negative impact on the Fund’s investment performance.

Unique Economic and Political Risks of Investing in Greater China. Investments in companies located or operating in Greater China (normally considered to be the geographical area that includes mainland China, Hong Kong, Macau and Taiwan) involve risks and considerations not typically associated with investments in the U.S. and other Western nations, such as greater government control over the economy; political, legal and regulatory uncertainty; nationalization, expropriation, or confiscation of property; difficulty in obtaining information necessary for investigations into and/or litigation against Chinese companies, as well as in obtaining and/or enforcing judgments; limited legal remedies for shareholders; alteration or discontinuation of economic reforms; military conflicts, either internal or with other countries; inflation, currency fluctuations and fluctuations in inflation and interest rates that may have negative effects on the economy and securities markets of Greater China; and Greater China’s dependency on the economies of other Asian countries, many of which are developing countries. Events in any one country within Greater China may impact the other countries in the region or Greater China as a whole. Export growth continues to be a major driver of China’s rapid economic growth. As a result, a reduction in spending on Chinese products and services, the institution of additional tariffs or other trade barriers (or the threat thereof), including as a result of trade tensions between China and the United States, or a downturn in any of the economies of China’s key trading partners may have an adverse impact on the Chinese economy. Further, health events, such as the recent coronavirus outbreak, may cause uncertainty and volatility in the Chinese economy, especially in the consumer discretionary (leisure, retail, gaming, tourism), industrials, and commodities sectors. Additionally, the inability of the Public Company Accounting Oversight Board (“PCAOB”) to inspect audit work papers and practices of PCAOB-registered accounting firms in China with respect to their audit work of U.S. reporting companies may impose significant additional risks associated with investments in China.

Certain securities issued by companies located or operating in Greater China, such as China A-shares, are subject to trading restrictions and suspensions, quota limitations and sudden changes in those limitations, and operational, clearing and settlement risks. Additionally, developing countries, such as those in Greater China, may subject the Fund’s investments to a number of tax rules, and the application of many of those rules may be uncertain. Moreover, China has implemented a number of tax reforms in recent years, and may amend or revise its existing tax laws and/or procedures in the future, possibly with retroactive effect. Changes in applicable Chinese tax law could reduce the after-tax profits of the Fund, directly or indirectly, including by reducing the after-tax profits of companies in China in which the Fund invests. Uncertainties in Chinese tax rules could result in unexpected tax liabilities for the Fund.

Risks of Investing Through Stock Connect . The Fund may invest directly in China A shares through Stock Connect, and will be subject to the following risks: sudden changes in quota limitations, application of trading suspensions, differences in trading days between the PRC and Stock Connect, operational risk, clearing and settlement risk and regulatory and taxation risk.

Eurozone Investment Risks. Certain of the regions in which the Fund may invest, including the European Union (EU), currently experience significant financial difficulties. Following the global economic crisis that

began in 2008, some of these countries have depended on, and may continue to be dependent on, the assistance from others such as the European Central Bank (ECB) or other governments or institutions, and failure to implement reforms as a condition of assistance could have a significant adverse effect on the value of investments in those and other European countries. In addition, countries that have adopted the euro are subject to fiscal and monetary controls that could limit the ability to implement their own economic policies, and could voluntarily abandon, or be forced out of, the euro. Such events could impact the market values of Eurozone and various other securities and currencies, cause redenomination of certain securities into less valuable local currencies, and create more volatile and illiquid markets. Additionally, the United Kingdom’s departure from the EU, commonly known as “Brexit,” may have significant political and financial consequences for Eurozone markets, including greater market volatility and illiquidity, currency fluctuations, deterioration in economic activity, a decrease in business confidence and an increased likelihood of a recession in the United Kingdom.

Risks of Growth Investing. If a growth company’s earnings or stock price fails to increase as anticipated, or if its business plans do not produce the expected results, the value of its securities may decline sharply. Growth companies may be newer or smaller companies that may experience greater stock price fluctuations and risks of loss than larger, more established companies. Newer growth companies tend to retain a large part of their earnings for research, development or investments in capital assets. Therefore, they may not pay any dividends for some time. Growth investing has gone in and out of favor during past market cycles and is likely to continue to do so. During periods when growth investing is out of favor or when markets are unstable, it may be more difficult to sell growth company securities at an acceptable price. Growth stocks may also be more volatile than other securities because of investor speculation.

Small- and Mid-Capitalization Companies Risks. Investing in securities of small- and mid-capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. Stocks of small- and mid-capitalization companies tend to be more vulnerable to changing market conditions, may have little or no operating history or track record of success, and may have more limited product lines and markets, less experienced management and fewer financial resources than larger companies. These companies’ securities may be more volatile and less liquid than those of more established companies. They may be more sensitive to changes in a company’s earnings expectations and may experience more abrupt and erratic price movements. Smaller companies’ securities often trade in lower volumes and in many instances, are traded over-the-counter or on a regional securities exchange, where the frequency and volume of trading is substantially less than is typical for securities of larger companies traded on national securities exchanges. Therefore, the securities of smaller companies may be subject to wider price fluctuations and it might be harder for the Fund to dispose of its holdings at an acceptable price when it wants to sell them. Since small- and mid-cap companies typically reinvest a high proportion of their earnings in their business, they may not pay dividends for some time, particularly if they are newer companies. It may take a substantial period of time to realize a gain on an investment in a small- or mid-cap company, if any gain is realized at all. The Fund measures the market capitalization of an issuer at the time of investment.

Industry and Sector Focus. The Fund may from time to time have a significant amount of its assets invested in a particular industry or sector. The prices of stocks of issuers in a particular industry or sector may go up and down in response to changes in economic conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than others. To the extent that the Fund has a significant amount of its assets invested in a particular industry or sector, its share values may fluctuate in response to events affecting that industry or sector. To some extent that risk may be limited by the Fund’s policy of not concentrating its investments in any one industry.

3 Invesco Developing Markets Fund

Risks of Investing in the Private Fund . The Private Fund is not registered under the Investment Company Act of 1940. As an investor in the Private Fund, the Fund does not have all of the protections offered to investors by the Investment Company Act of 1940. However, the Private Fund is controlled by the Fund and managed by OppenheimerFunds, Inc. The Private Fund may invest substantially all of its assets in a limited number of issuers or a single issuer. To the extent that it does so, the Private Fund is more subject to the risks associated with and developments affecting such issuers than a fund that invests more widely.

Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of the investment process to implement the Fund’s investment strategy in pursuit of its investment objective may vary across types of eligible investments and issuers, and not every ESG factor may be identified or evaluated for every investment. The Fund’s portfolio will not be solely based on ESG considerations, and therefore the issuers in which the Fund invests may not be considered ESG-focused companies. The incorporation of ESG factors may affect the Fund’s exposure to certain issuers or industries and may not work as intended. The Fund may underperform other funds that do not assess an issuer’s ESG factors or that use a different methodology to identify and/or incorporate ESG factors. Information used by the Fund to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers as ESG is not a uniformly defined characteristic. There is no guarantee that the evaluation of ESG considerations will be additive to the Fund’s performance.

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

Performance Information

The bar chart and performance table provide an indication of the risks of investing in the Fund. The Fund has adopted the performance of the Oppenheimer Developing Markets Fund (the predecessor fund) as the result of a reorganization of the predecessor fund into the Fund, which was consummated after the close of business on May 24, 2019 (the “Reorganization”). Prior to the Reorganization, the Fund had not yet commenced operations. The bar chart shows changes in the performance of the predecessor fund and the Fund from year to year as of December 31. The performance table compares the predecessor fund’s and the Fund’s performance to that of a broad-based securities market benchmark.

The Fund’s (and the predecessor fund’s) past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. The returns shown for periods ending on or prior to May 24, 2019 are those of the Class A, Class C, Class R, Class Y and Class I shares of the predecessor fund. Class A, Class C, Class R, Class Y and Class I shares of the predecessor fund were reorganized into Class A, Class C, Class R, Class Y and Class R6 shares, respectively, of the Fund after the close of business on May 24, 2019. Class A, Class C, Class R, Class Y and Class R6 shares’ returns of the Fund will be different from the returns of the predecessor fund as they have different expenses. Class R5 shares’ returns of the Fund will be different from Class A shares’ returns of the Fund and the predecessor fund as they have different expenses. Performance for Class A shares has been restated to reflect the Fund’s applicable sales charge.

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

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

Tax Information

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

Payments to Broker-Dealers and Other Financial Intermediaries

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

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

Objective(s), Principal Investment Strategies and Risks

The Fund’s investment objective is to seek capital appreciation. The Fund’s investment objective is fundamental and may not be changed without shareholder approval.

The following strategies and types of investments are the ones that the Fund considers to be the most important in seeking to achieve its

investment objective and the following risks are those the Fund expects its portfolio to be subject to as a whole.

Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions which are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, or adverse investor sentiment generally. The value of the Fund’s investments may also go up or down due to factors that affect an individual issuer or a particular industry or sector, such as changes in production costs and competitive conditions within an industry. In addition, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or other events may have a significant impact on the value of the Fund’s investments, as well as the financial markets and global economy generally. Such circumstances may also impact the ability of the Adviser to effectively implement the Fund’s investment strategy. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.

■

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

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-sized 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.

Foreign Investing. The Fund may buy stocks and other equity securities of companies that are organized under the laws of a foreign country or that have a substantial portion of their operations or assets in a

foreign country or countries, or that derive a substantial portion of their revenue or profits from businesses, investments or sales outside of the United States.

The Fund may purchase American Depositary Shares (ADS) as part of American Depositary Receipt (ADR) issuances, which are negotiable certificates issued by a U.S. bank representing a specified number of shares in a foreign stock traded on a U.S. exchange. ADS and ADRs are subject to some of the special considerations and risks that apply to foreign securities traded and held abroad.

Risks of Foreign Investing. Securities traded in foreign markets often involve special risks not present in U.S. investments that can increase the chances the Fund will lose money. Additional information regarding certain of the risks associated with foreign investing is provided below.

■

Foreign Market Risk. If there are fewer investors in a particular foreign market, securities traded in that market may be less liquid and more volatile than U.S. securities and more difficult to price. Foreign markets may also be subject to delays in the settlement of transactions and difficulties in pricing securities. If the Fund is delayed in settling a purchase or sale transaction, it may not receive any return on the invested assets or it may lose money if the value of the security declines. It may also be more expensive for the Fund to buy or sell securities in certain foreign markets than in the United States, which may increase the Fund’s expense ratio.

■

Foreign Economy Risk. Foreign economies may be more vulnerable to political or economic changes than the U.S. economy. They may be more concentrated in particular industries or may rely on particular resources or trading partners to a greater extent. Certain foreign economies may be adversely affected by shortages of investment capital or by high rates of inflation. Changes in economic or monetary policy in the U.S. or abroad may also have a greater impact on the economies of certain foreign countries.

■

Foreign Governmental and Regulatory Risks. Foreign companies may not be subject to the same accounting and disclosure requirements as U.S. companies. As a result there may be less accurate information available regarding a foreign company’s operations and financial condition. Foreign companies may be subject to capital controls, nationalization, or confiscatory taxes. There may be less government regulation of foreign issuers, exchanges and brokers than in the United States. Some countries also have restrictions that limit foreign ownership and may impose penalties for increases in the value of the Fund’s investment. The value of the Fund’s foreign investments may be affected if it experiences difficulties in enforcing legal judgments in foreign courts.

■

Foreign Currency Risk. A change in the value of a foreign currency against the U.S. dollar will result in a change in the U.S. dollar value of securities denominated in that foreign currency. If the U.S. dollar rises in value against a foreign currency, a security denominated in that currency will be worth less in U.S. dollars and if the U.S. dollar decreases in value against a foreign currency, a security denominated in that currency will be worth more in U.S. dollars. The dollar value of foreign investments may also be affected by exchange controls. Foreign currency exchange transactions may impose additional costs on the Fund. The Fund can also invest in derivative instruments linked to foreign currencies. The change in value of a foreign currency against the U.S. dollar will result in a change in the U.S. dollar value of derivatives linked to that foreign currency. The investment adviser’s selection of foreign currency-denominated investments may not perform as expected. Currency derivative investments may be particularly volatile and subject to greater risks than other types of foreign currency-denominated investments.

■

Foreign Custody Risk. There may be very limited regulatory oversight of certain foreign banks or securities depositories that hold foreign securities and foreign currency and the laws of certain countries may

limit the ability to recover such assets if a foreign bank or depository or their agents goes bankrupt. There may also be an increased risk of loss of portfolio securities.

■

Time Zone Arbitrage. If the Fund invests a significant amount of its assets in foreign securities, it may be exposed to “time-zone arbitrage” attempts by investors seeking to take advantage of differences in the values of foreign securities that might result from events that occur after the close of the foreign securities market on which a security is traded and before the close of the New York Stock Exchange that day, when the Fund’s net asset value is calculated. If such time zone arbitrage were successful, it might dilute the interests of other shareholders. However, the Fund’s use of “fair value pricing” under certain circumstances, to adjust the closing market prices of foreign securities to reflect what the investment adviser and the Board believe to be their fair value, may help deter those activities.

■

Globalization Risks. The growing inter-relationship of global economies and financial markets has increased the effect of conditions in one country or region on issuers of securities in a different country or region. In particular, the adoption or prolongation of protectionist trade policies by one or more countries, changes in economic or monetary policy in the United States or abroad, or a slowdown in the U.S. economy, could lead to a decrease in demand for products and reduced flows of capital and income to companies in other countries.

■

Regional Focus. At times, the Fund might increase the relative emphasis of its investments in a particular region of the world. Securities of issuers in a region might be affected by changes in economic conditions or by changes in government regulations, availability of basic resources or supplies, or other events that affect that region more than others. If the Fund has a greater emphasis on investments in a particular region, it may be subject to greater risks from adverse events that occur in that region than a fund that invests in adifferent region or that is more geographically diversified. Political, social or economic disruptions in the region may adversely affect the values of the Fund’s holdings.

Risks of Developing and Emerging Markets. Investments in developing and emerging market countries are subject to all the risks associated with foreign investing, however, these risks may be magnified in developing and emerging markets. Investments in securities of issuers in developing or emerging market countries may be considered speculative. Additional information regarding certain of the risks associated with investing in developing and emerging markets is provided below.

■

Less Developed Securities Markets. Developing or emerging market countries may have less well-developed securities markets and exchanges. Consequently they have lower trading volume than the securities markets of more developed countries and may be substantially less liquid than those of more developed countries. Unexpected market closures may also affect investments in developing or emerging markets.

■

Transaction Settlement. Settlement procedures in developing or emerging markets may differ from those of more established securities markets, and settlement delays may result in the inability to invest assets or to dispose of portfolio securities in a timely manner. As a result there could be subsequent declines in the value of the portfolio security, a decrease in the level of liquidity of the portfolio or, if there is a contract to sell the security, a possible liability to the purchaser.

■

Price Volatility. Securities prices in developing or emerging markets may be significantly more volatile than is the case in more developed nations of the world, which may lead to greater difficulties in pricing securities. Developing or emerging market countries may also have higher rates of inflation and more rapid and extreme fluctuations in inflation rates and greater sensitivity to interest rate changes.

■

Less Developed Governments and Economies. The governments of developing or emerging market countries may be more unstable than the governments of more developed countries. In addition, the economies of developing or emerging market countries may be more dependent on relatively few industries or investors that may be highly vulnerable to local and global changes and trade conditions. Developing or emerging market countries may be subject to social, political, or economic instability. Further, the value of the currency of a developing or emerging market country may fluctuate more than the currencies of countries with more mature markets, and there may be difficulty related to the quality, availability and timeliness of information. In addition, the taxation systems at the federal, regional and local levels in developing or emerging market countries may be less transparent and inconsistently enforced, and subject to sudden change. Developing or emerging market countries may have a higher degree of corruption and fraud than developed market countries, as well as counterparties and financial institutions with less financial sophistication, creditworthiness and/or resources.

■

Less Developed Legal Systems. Developing or emerging market countries may have less developed legal systems allowing for enforcement of private property rights and/or redress for injuries to private property, such as bankruptcy. The ability to bring and enforce actions in developing or emerging market countries, or to obtain information needed to pursue or enforce such actions, may be limited and shareholder claims may be difficult or impossible to pursue.

■

Government Restrictions. In certain developing or emerging market countries, government approval may be required for the repatriation of investment income, capital or the proceeds of sales of securities by foreign investors. Other government restrictions may include confiscatory taxation, expropriation or nationalization of company assets, restrictions on foreign ownership of local companies, protectionist measures, and practices such as share blocking.

■

Privatization Programs. The governments in some developing or emerging market countries have been engaged in programs to sell all or part of their interests in government-owned or controlled enterprises. However, in certain developing or emerging market countries, the ability of foreign entities to participate in privatization programs may be limited by local law. There can be no assurance that privatization programs will be successful.

■

Financial Reporting Standards. Companies in developing or emerging market countries generally may be subject to less stringent regulatory, disclosure, financial reporting, accounting, auditing and recordkeeping standards than companies in more developed countries and, as a result, the nature and quality of such information may vary. Information about such companies may be less available and reliable and, therefore, the ability to conduct adequate due diligence in developing or emerging markets may be limited which can impede the Fund’s ability to evaluate such companies. In addition, certain developing or emerging market countries have material limitations on Public Company Accounting Oversight Board (“PCAOB”) inspection, investigation and enforcement capabilities which hinder the ability to engage in independent oversight or inspection of accounting firms located in or operating in certain developing or emerging markets; therefore, there is no guarantee that the quality of financial reporting or the audits conducted by audit firms of developing or emerging market issuers meet PCAOB standards.

Geographic Focus Risk. The Fund may from time to time have a substantial amount of its assets invested in securities of issuers located in a single country or a limited number of countries. If the Fund focuses its investments in this manner, adverse economic, political or social conditions in those countries may have a significant negative impact on the Fund’s investment performance. This risk is heightened if the Fund focuses its

investments in emerging market countries or developed countries prone to periods of instability.

Unique Economic and Political Risks of Investing in Greater China. Investments in companies located or operating in Greater China (normally considered to be the geographical area that includes mainland China, Hong Kong, Macau and Taiwan) involve risks and considerations not typically associated with investments in the U.S. and other Western nations, such as greater government control over the economy; political, legal and regulatory uncertainty; nationalization, expropriation, or confiscation of property; difficulty in obtaining information necessary for investigations into and/or litigation against Chinese companies, as well as in obtaining and/or enforcing judgments; limited legal remedies for shareholders; alteration or discontinuation of economic reforms; military conflicts, either internal or with other countries; inflation, currency fluctuations and fluctuations in inflation and interest rates that may have negative effects on the economy and securities markets of Greater China; and Greater China’s dependency on the economies of other Asian countries, many of which are developing countries. Events in any one country within Greater China may impact the other countries in the region or Greater China as a whole. For example, changes to their political and economic relationships with mainland China could adversely impact the Fund’s investments in Taiwan and Hong Kong. Further, health events, such as the recent coronavirus outbreak, may cause uncertainty and volatility in the Chinese economy, especially in the consumer discretionary (leisure, retail, gaming, tourism), industrials, and commodities sectors. Additionally, the inability of the Public Company Accounting Oversight Board (“PCAOB”) to inspect audit work papers and practices of PCAOB-registered accounting firms in China with respect to their audit work of U.S. reporting companies may impose significant additional risks associated with investments in China.

Certain securities issued by companies located or operating in Greater China, such as China A-shares, are subject to trading restrictions and suspensions, quota limitations and sudden changes in those limitations, and operational, clearing and settlement risks. Significant portions of the Chinese securities markets may become rapidly illiquid, as Chinese issuers have the ability to suspend the trading of their equity securities, and have shown a willingness to exercise that option in response to market volatility and other events. The liquidity of Chinese securities may shrink or disappear suddenly and without warning as a result of adverse economic, market or political events, or adverse investor perceptions, whether or not accurate.

Export growth continues to be a major driver of China’s rapid economic growth. As a result, a reduction in spending on Chinese products and services, the institution of tariffs or other trade barriers (or the threat thereof), or a downturn in any of the economies of China’s key trading partners may have an adverse impact on the Chinese economy. The ongoing trade dispute and imposition of tariffs between China and the United States continues to introduce uncertainty into the Chinese economy and may result in reductions in international trade, the oversupply of certain manufactured goods, substantial price reductions of goods and possible failure of individual companies and/or large segments of China’s export industry, which could have a negative impact on the Fund’s performance. Events such as these and their consequences are difficult to predict and it is unclear whether further tariffs may be imposed or other escalating actions may be taken in the future.

Additionally, developing countries, such as those in Greater China, may subject the Fund’s investments to a number of tax rules, and the application of many of those rules may be uncertain. Moreover, China has implemented a number of tax reforms in recent years, and may amend or revise its existing tax laws and/or procedures in the future, possibly with retroactive effect. Changes in applicable Chinese tax law could reduce the after-tax profits of the Fund, directly or indirectly, including by reducing the after-tax profits of companies in China in which the Fund invests. Chinese taxes that may apply to the Fund’s investments include income tax or withholding tax on dividends, interest or gains earned by the Fund, business tax and stamp

7 Invesco Developing Markets Fund

duty. Uncertainties in Chinese tax rules could result in unexpected tax liabilities for the Fund.

Investing in China A Shares. The portfolio manager may pursue the Fund’s investment objective by investing a portion of the Fund’s assets in China A shares (China A Shares), which are shares of companies incorporated in the People’s Republic of China (PRC) and listed on the Shanghai Stock Exchange (SSE) or the Shenzhen Stock Exchange (SZSE). The China A Shares market is an active Chinese market that includes a large number of Chinese equities as well as smaller or emerging Chinese companies that may not list shares elsewhere. The China Securities Regulatory Commission (CSRC) and the Securities and Futures Commission of Hong Kong have approved programs which establish mutual stock market access between the PRC and Hong Kong, via the Shanghai-Hong Kong Stock Connect and the Shenzhen-Hong Kong Stock Connect (Stock Connect). Stock Connect is a securities trading and clearing program developed by Hong Kong Exchanges and Clearing Limited, the SSE, the SZSE and China Securities Depository and Clearing Corporation Limited (ChinaClear) designed to achieve mutual stock market access between the PRC and Hong Kong.

The Fund may invest directly in certain eligible China A Shares through Stock Connect or, for operational efficiency and regulatory considerations, through an investment in a private investment vehicle organized under Delaware law (the Private Fund). The Private Fund may invest in companies established or operating in, or with significant exposure to, the PRC or other developing markets countries. The Private Fund’s managing member, OppenheimerFunds, Inc., has full and exclusive discretionary authority to manage the day-to-day operations of the Private Fund and to invest its assets. The Fund’s investment in the Private Fund may vary based on the portfolio manager’s use of different types of investments that provide exposure to Chinese securities, e.g., through Stock Connect. Since the Fund may invest a portion of its assets in the Private Fund, the Fund may be considered to be investing indirectly in such securities through the Private Fund.

Risks of Investing in China A Shares. Investments in Class A Shares of Chinese companies involve certain risks and special considerations not typically associated with investments in U.S. companies, such as greater government control over the economy, political and legal uncertainty, currency fluctuations or blockage, the risk that the Chinese government may decide not to continue to support economic reform programs and the risk of nationalization or expropriation of assets. Additionally, the Chinese securities markets are emerging markets subject to the special risks applicable to developing and emerging market countries described elsewhere in this prospectus.

Risks of Investing Through Stock Connect. Trading on Stock Connect is subject to an aggregated daily quota on purchases that can change without notice, restricting the Fund’s ability to invest in China A Shares on a timely basis. The Stock Exchange of Hong Kong Limited (SEHK), SSE and SZSE may suspend trading of individual securities or more broadly in response to market events, which may adversely affect the Fund’s ability to access the PRC market. Stock Connect only operates on days when both markets are open for trading and banks in both markets are also open on corresponding settlement days, thus the Fund may not be able to trade China A Shares on days when Stock Connect is not trading but normal trading for the PRC market otherwise occurs. Prices may fluctuate on China A Shares on days when Stock Connect is not trading. The Fund’s ability to enter and exit trades via Stock Connect on a timely basis is also restricted by a prohibition on turnaround (day) trading on the China A Share market (i.e., investors cannot purchase and sell the same securities via Stock Connect in the same trading day). Stock Connect relies on the maintenance by relevant market participants of certain information technology, risk management and other requirements. There is no assurance that relevant exchange trading systems and market participants will function properly or continue to adapt to changes. If relevant systems fail to function properly, trading disruptions can occur that adversely affect the Fund’s ability to

access the China A Share market. The Fund is also subject to risks related to the clearing and settlement of securities, including for example where a default occurs in connection with the settlement of cross border trades that could cause potential delays in the Fund’s recovery process or its ability to fully recover losses. It is expected that the list of eligible securities on Stock Connect will be subject to review and may change periodically. Hong Kong and overseas investors are subject to a restriction on single foreign investors’ holding no more than 10% of the total issue shares, as well as a restriction that, in the aggregate, foreign investors’ hold no more than 30% of the total issue shares. Therefore, foreign investors could be required to unwind their positions if excessive shareholding restrictions are exceeded.

Regulations and implementation rules applicable to Stock Connect are novel and untested, and it is uncertain as to how they will be applied. There is also general uncertainty regarding changes in government policies, taxation, currency repatriation restrictions, permitted foreign ownership levels and other laws or regulations that impact Stock Connect. Under current PRC and CSRC tax guidance, capital gains realized by the Fund from trading of eligible China A Shares on the SSE under Stock Connect may currently enjoy a temporary exemption from PRC income and business tax. It is not known when such exemption will expire and whether other taxes will be applicable to trading securities under Stock Connect in the future. There is no guarantee that relevant tax regulations and guidance, including the temporary tax exemption with respect to Stock Connect, will continue to apply or will not be repealed and re-imposed retrospectively, or that no new tax regulations and practices relating to Stock Connect will be promulgated in the future, possibly with retroactive effect. Such changes could have a significant adverse effect on the Fund, including reducing returns, reducing the value of the Fund’s investments, and possibly impairing capital invested by the Fund.

Eurozone Investment Risks. The European Union (EU) is an economic and political union of most western European countries and a growing number of eastern European countries, collectively known as “member states.” One of the key mandates of the EU is the establishment and administration of a common single market, consisting of, among other things, a single currency and a common trade policy. In order to pursue this goal, member states established the Economic and Monetary Union (EMU), which sets out different stages and commitments that member states need to follow to achieve greater economic and monetary policy coordination, including the adoption of a single currency, the euro. Many member states have adopted the euro as their currency and, as a result, are subject to the monetary policies of the European Central Bank (ECB).

The global economic crisis that began in 2008 has caused severe financial difficulties for many EU member states, pushing some to the brink of insolvency and causing others to experience recession, large public debt, restructuring of government debt, credit rating downgrades and an overall weakening of banking and financial sectors. Some of those countries have depended on, and may continue to be dependent on, the assistance from others such as the ECB, the International Monetary Fund (IMF), or other governments and institutions to address those issues. Failure by one or more EU member states to implement reforms or attain a certain performance level imposed as a condition of assistance, or an insufficient level of assistance, could deepen or prolong the economic downturn which could have a significant adverse effect on the value of investments in those and other European countries. By adopting the euro as its currency, members of the EMU are subject to fiscal and monetary controls that could limit to some degree the ability to implement their own economic policies. Additionally, EMU member states could voluntarily abandon the euro or involuntarily be forced out of the euro, including by way of a partial or complete dissolution of the EMU. The effects of such outcomes on the rest of the Eurozone and global markets as a whole are unpredictable, but are likely to be negative, including adversely impacted market values of Eurozone and various other securities and currencies, redenomination of certain securities into less valuable local currencies, and more volatile and illiquid markets. Under such circumstances, investments denominated in

8 Invesco Developing Markets Fund

euros or replacement currencies may be difficult to value, the ability to operate an investment strategy in connection with euro-denominated securities may be significantly impaired and the value of euro-denominated investments may decline significantly and unpredictably. Additionally, the United Kingdom’s departure from the EU, known as “Brexit,” may have significant political and financial consequences for Eurozone markets, including greater market volatility and illiquidity, currency fluctuations, deterioration in economic activity, a decrease in business confidence and an increased likelihood of a recession in the United Kingdom. While the full impact of Brexit is unknown, market disruption in the EU and globally may have a negative effect on the value of the Fund’s investments. Additionally, the risks related to Brexit could be more pronounced if one or more additional EU member states seek to leave the EU.

Growth Investing. Growth companies are companies whose earnings and stock prices are expected to grow at a faster rate than the overall market. Growth companies can be new companies or established companies that may be entering a growth cycle in their business. Their anticipated growth may come from developing new products or services or from expanding into new or growing markets. Growth companies may be applying new technologies, new or improved distribution methods or new business models that could enable them to capture an important or dominant market position. They may have a special area of expertise or the ability to take advantage of changes in demographic or other factors in a more profitable way. Newer growth companies generally tend to invest a large part of their earnings into research, development or capital assets. Although newer growth companies may not pay any dividends for some time, their stocks may be valued because of their potential for price increases.

Small- and Mid-Capitalization Risks. Investing in securities of small- and mid-capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. Stocks of small- and mid-capitalization companies tend to be more vulnerable to changing market conditions, may have little or no operating history or track record of success, and may have more limited product lines and markets, less experienced management and fewer financial resources than larger companies. These companies’ securities may be more volatile and less liquid than those of more established companies. They may be more sensitive to changes in a company’s earnings expectations and may experience more abrupt and erratic price movements. Smaller companies’ securities often trade in lower volumes and in many instances, are traded over-the-counter or on a regional securities exchange, where the frequency and volume of trading is substantially less than is typical for securities of larger companies traded on national securities exchanges. Therefore, the securities of smaller companies may be subject to wider price fluctuations and it might be harder for the Fund to dispose of its holdings at an acceptable price when it wants to sell them. Since small- and mid-cap companies typically reinvest a high proportion of their earnings in their business, they may not pay dividends for some time, particularly if they are newer companies. It may take a substantial period of time to realize a gain on an investment in a small- or mid-cap company, if any gain is realized at all.

The Fund measures the market capitalization of an issuer at the time of investment. Because the relative sizes of companies change over time as the securities market changes, the Fund’s definition of what is a “small-capitalization,” “mid-capitalization” or “large-capitalization” company may change over time as well. Although the Fund is not required to sell the securities of companies whose market capitalizations have grown or decreased, it might sell some of those holdings to try to adjust the dollar-weighted median capitalization of its portfolio. That might cause the Fund to realize capital gains on an investment and could increase taxable distributions to shareholders. When the Fund invests in smaller company securities that might trade infrequently, investors might seek to trade Fund shares based on their knowledge or understanding of the value of those securities (this is sometimes referred to as “price arbitrage”). If such price arbitrage were successful, it might interfere with the efficient management of the Fund’s portfolio and the Fund may be required to sell securities at disadvantageous times or prices to satisfy the liquidity requirements created by that activity. Successful price arbitrage might also dilute the value of fund shares held by other shareholders.

Industry and Sector Focus. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of stocks of issuers in a particular industry or sector may go up and down in response to changes in economic conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than others. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its share values may fluctuate in response to events affecting that industry or sector. To some extent that risk may be limited by the Fund’s policy of not concentrating its investments in any one industry.

Risks of Investing Through the Private Fund. Investments in Class A shares of Chinese companies involve certain risks and special considerations not typically associated with investments in U.S. companies, such as greater government control over the economy, political and legal uncertainty, currency fluctuations or blockage, the risk that the Chinese government may decide not to continue to support economic reform programs and the risk of nationalization or expropriation of assets. Additionally, the Chinese securities markets are emerging markets and may be characterized by relatively low trading volume, which may result in substantially less liquidity and greater price volatility than more developed markets. Some of these risks may be more pronounced for the China A Shares market than for Chinese securities markets generally because the A-share market is subject to greater government restrictions and control. The Private Fund’s China A Shares investment quota may be reduced or revoked by the Chinese government at any time, including if redemptions reduce the amount invested in China A Shares by the Private Fund below the current quota amount. Further, the Private Fund may invest substantially all of its assets in a limited number of issuers or a single issuer. To the extent that it does so, the Private Fund is more subject to the risks associated with and developments affecting such issuers than a fund that invests more widely. In addition, although it is not currently expected to do so, the Private Fund may invest a portion of its assets in certain exchange-traded and over-the-counter financial instruments from countries other than China.

The Fund will deem its investment in the Private Fund to be illiquid and subject to the Fund’s policy regarding investments in illiquid investments. The Fund will comply with Rule 22e-4 in managing its illiquid investments. The Fund currently will invest no more than 10% of its net assets in the Private Fund. Interests in the Private Fund may be redeemed, and net redemption proceeds may be repatriated only once each day. In addition, the Private Fund is subject to a monthly accumulated repatriation limit equal to 20% of the Private Fund’s total investment in China A Shares and other QFII permitted securities as of the end of the previous year. The Fund’s redemption of interests from the Private Fund may be limited accordingly.

The Private Fund is not registered under the Investment Company Act of 1940, as amended, and the rules and regulations promulgated thereunder

9 Invesco Developing Markets Fund

by the SEC. To the extent the Fund invests in the Private Fund, it will not have all of the protections offered to investors by the Investment Company Act of 1940.

Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of the investment process to implement the Fund’s investment strategy in pursuit of its investment objective may vary across types of investments and issuers eligible for investment, and not every ESG factor may be identified or evaluated for every investment. The Fund’s portfolio will not be solely based on ESG considerations, and therefore the issuers in which the Fund invests may not be considered ESG-focused companies. The incorporation of ESG factors may affect the Fund’s exposure to certain issuers or industries and may not work as intended. The Fund may underperform other funds that do not assess an issuer’s ESG factors as part of the investment process or that use a different methodology to identify and/or incorporate ESG factors. As investors can differ in their views regarding ESG factors, the Fund may invest in issuers that do not reflect the views with respect to ESG of any particular investor. Information used by the Fund to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers as ESG is not a uniformly defined characteristic, which could negatively impact the Fund’s ability to accurately assess a company, which could negatively impact the Fund’s performance. There is no guarantee that the evaluation of ESG considerations will be additive to the Fund’s performance.

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

Other Investment Strategies and Risks

The Fund can also use the investment techniques and strategies described below. The Fund might not use all of these techniques or strategies or might only use them from time to time.

Diversification and Concentration. The Fund is a diversified fund. It attempts to reduce its exposure to the risks of individual securities by diversifying its investments across a broad number of different issuers. The Fund will not concentrate its investments in issuers in any one industry. At times, however, the Fund may emphasize investments in some industries or sectors more than others. The prices of securities of issuers in a particular industry or sector may go up and down in response to changes in economic conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than others. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its share values may fluctuate in response to events affecting that industry or sector. The Securities and Exchange Commission has taken the position that investment of more than 25% of a fund’s total assets in issuers in the same industry constitutes concentration in that industry. That limit does not apply to securities issued or guaranteed by the U.S. government or its agencies and instrumentalities. For purposes of compliance with its concentration policy, the Fund will consider portfolio investments held by underlying investment companies in which the Fund invests, to the extent that the Fund has sufficient information about such portfolio investments. The Fund will make reasonable efforts to obtain such information.

Other Equity Securities. In addition to common stocks, the Fund can invest in other equity or “equity equivalents” securities such as preferred stocks, convertible securities, rights or warrants.

■

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. The dividends on preferred stock may be cumulative (they remain a liability of the company until paid) or non-cumulative. The fixed dividend rate of preferred stocks may cause their prices to behave more like those of debt securities. If prevailing interest rates rise, the fixed dividend on preferred stock may be less attractive, which may cause the price of preferred stock to decline.

■

Warrants are options to purchase equity securities at specific prices that are valid for a specific period of time. Their prices do not necessarily move parallel to the prices of the underlying securities, and can be more volatile than the price of the underlying securities. If the market price of the underlying security does not exceed the exercise price during the life of the warrant, the warrant will expire worthless and any amount paid for the warrant will be lost. The market for warrants may be very limited and it may be difficult to sell a warrant promptly at an acceptable price. 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.

■

A convertible security 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. Convertible securities may offer the Fund the ability to participate in stock market movements while also seeking some current income. Convertible securities may provide more income than common stock but they generally provide less income than comparable non-convertible debt securities. Convertible securities are subject to credit and interest rate risk, however credit ratings of convertible securities generally have less impact on the value of the securities than they do for non-convertible debt securities.

Investing in Domestic Securities. The Fund can invest in common and preferred stocks and debt securities of U.S. companies. It can also hold U.S. corporate and government debt securities for defensive and liquidity purposes. Under normal market conditions, the Fund does not expect to invest a significant amount of its assets in securities of U.S. issuers.

Debt Securities. Debt securities can include debt securities of foreign companies and governments, including those in developing countries. However, the Fund does not invest for income and does not expect to invest significant amounts in debt securities, unless they are convertible securities considered to be “equity equivalents,” or debt securities purchased for temporary defensive or liquidity purposes.

Debt securities may be subject to the following risks:

■

Interest Rate Risk. Interest rate risk is the risk that rising interest rates, or an expectation of rising interest rates in the near future, will cause the values of the Fund’s investments in debt securities to decline. The values of debt securities usually change when prevailing interest rates change. When interest rates rise, the values of outstanding debt securities generally fall, and those securities may sell at a discount from their face amount. Additionally, when interest rates rise, the decrease in values of outstanding debt securities may not be offset by higher income from new investments. When interest rates fall, the values of already-issued debt securities generally rise and the Fund’s investments in new securities may be at lower yields and may reduce the Fund’s income. The values of longer-term debt securities usually change more than the values of shorter-term debt securities when interest rates change; thus, interest rate risk is

usually greater for securities with longer maturities or durations. “Zero-coupon” or “stripped” securities may be particularly sensitive to interest rate changes. Risks associated with rising interest rates are heightened given that interest rates in the U.S. are near historic lows. Interest rate changes may have different effects on the values of mortgage-related securities because of prepayment and extension risks.

■

Duration Risk. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities are more volatile and thus more likely to decline in price, and to a greater extent, than shorter-duration debt securities, in a rising interest-rate environment. “Effective duration” attempts to measure the expected percentage change in the value of a bond or portfolio resulting from a change in prevailing interest rates. The change in the value of a bond or portfolio can be approximated by multiplying its duration by a change in interest rates. For example, if a bond has an effective duration of three years, a 1% increase in general interest rates would be expected to cause the bond’s value to decline about 3% while a 1% decrease in general interest rates would be expected to cause the bond’s value to increase 3%. The duration of a debt security may be equal to or shorter than the full maturity of a debt security.

■

Credit Risk. Credit risk is the risk that the issuer of a security might not make interest and principal payments on the security as they become due. U.S. government securities generally have lower credit risks than securities issued by private issuers or certain foreign governments. If an issuer fails to pay interest, the Fund’s income might be reduced, and if an issuer fails to repay principal, the value of the security might fall and the Fund could lose the amount of its investment in the security. The extent of this risk varies based on the terms of the particular security and the financial condition of the issuer. A downgrade in an issuer’s credit rating or other adverse news about an issuer, for any reason, can reduce the market value of that issuer’s securities.

■

Credit Spread Risk. Credit spread risk is the risk that credit spreads (i.e., the difference in yield between securities that is due to differences in their credit quality) may increase when the market expects lower grade bonds to default more frequently. Widening credit spreads may quickly reduce the market values of the Fund’s lower-rated and unrated securities. 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.

■

Extension Risk. Extension risk is the risk that, if interest rates rise rapidly, prepayments on certain debt securities may occur at a slower rate than expected, and the expected maturity of those securities could lengthen as a result. Securities that are subject to extension risk generally have a greater potential for loss when prevailing interest rates rise, which could cause their values to fall sharply. Extension risk is particularly prevalent for a callable security where an increase in interest rates could result in the issuer of that security choosing not to redeem the security as anticipated on the security’s call date. Such a decision by the issuer could have the effect of lengthening the debt security’s expected maturity, making it more vulnerable to interest rate risk and reducing its market value.

■

Reinvestment Risk. Reinvestment risk is the risk that when interest rates fall, the Fund may be required to reinvest the proceeds from a security’s sale or redemption at a lower interest rate. Callable bonds are generally subject to greater reinvestment risk than non-callable bonds.

■

Prepayment Risk. Certain fixed-income securities (in particular mortgage-related securities) are subject to the risk of unanticipated prepayment. Prepayment risk is the risk that, when interest rates fall, the issuer will redeem the security prior to the security’s expected

maturity, or that borrowers will repay the loans that underlie these fixed-income securities more quickly than expected, thereby causing the issuer of the security to repay the principal prior to expected maturity. The Fund may need to reinvest the proceeds at a lower interest rate, reducing its income. Securities subject to prepayment risk generally offer less potential for gains when prevailing interest rates fall. If the Fund buys those securities at a premium, accelerated prepayments on those securities could cause the Fund to lose a portion of its principal investment. The impact of prepayments on the price of a security may be difficult to predict and may increase the security’s price volatility. Interest-only and principal-only securities are especially sensitive to interest rate changes, which can affect not only their prices but can also change the income flows and repayment assumptions about those investments.

■

Event Risk. If an issuer of debt securities is the subject of a buyout, debt restructuring, merger or recapitalization that increases its debt load, it could interfere with its ability to make timely payments of interest and principal and cause the value of its debt securities to fall.

Fixed-Income Market Risks. The fixed-income securities market can be susceptible to unusual volatility and illiquidity. Volatility and illiquidity may be more pronounced in the case of lower-rated and unrated securities. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates), which are near historic lows in the U.S. and in other countries. During times of reduced market liquidity, the Fund may not be able to readily sell bonds at the prices at which they are carried on the Fund’s books. If the Fund needed to sell large blocks of bonds to meet shareholder redemption requests or to raise cash, those sales could further reduce the bonds’ prices. An unexpected increase in Fund redemption requests (including requests from shareholders who may own a significant percentage of the Fund’s shares), which may be triggered by market turmoil or an increase in interest rates, as well as other adverse market and economic developments, could cause the Fund to sell its holdings at a loss or at undesirable prices and adversely affect the Fund’s share price and increase the Fund’s liquidity risk, Fund expenses and/or taxable distributions, if applicable. Similarly, the prices of the Fund’s holdings could be adversely affected if an investment account managed similarly to the Fund was to experience significant redemptions and that account was required to sell its holdings at an inopportune time. The liquidity of an issuer’s securities may decrease as a result of a decline in an issuer’s credit rating, the occurrence of an event that causes counterparties to avoid transacting with the issuer, or an increase in the issuer’s cash outflows, as well as other adverse market and economic developments. A lack of liquidity or other adverse credit market conditions may hamper the Fund’s ability to sell the debt securities in which it invests or to find and purchase suitable debt instruments.

Economic and other market developments can adversely affect fixed-income securities markets in the United States, Europe and elsewhere. At times, participants in debt securities markets may develop concerns about the ability of certain issuers of debt securities to make timely principal and interest payments, or they may develop concerns about the ability of financial institutions that make markets in certain debt securities to facilitate an orderly market. Those concerns may impact the market price or value of those debt securities and may cause increased volatility in those debt securities or debt securities markets. Under some circumstances, those concerns could cause reduced liquidity in certain debt securities markets, reducing the willingness of some lenders to extend credit, and making it more difficult for borrowers to obtain financing on attractive terms (or at all).

Changes to monetary policy by the Federal Reserve or other regulatory actions could expose fixed income and related markets to heightened volatility, interest rate sensitivity and reduced liquidity, which may impact the Fund’s operations, universe of potential investment options, and return potential.

11 Invesco Developing Markets Fund

In addition, although the fixed-income securities markets have grown significantly in the last few decades, regulations and business practices have led some financial intermediaries to curtail their capacity to engage in trading (i.e., “market making”) activities for certain debt securities. As a result, dealer inventories of fixed-income securities, which provide an indication of the ability of financial intermediaries to make markets in fixed income securities, are near historic lows relative to market size. Because market makers help stabilize the market through their financial intermediary services, further reductions in dealer inventories could have the potential to decrease liquidity and increase volatility in the fixed-income securities markets.

Investing in Special Situations.. At times, the Fund may seek to benefit from what are considered to be “special situations,” such as mergers, reorganizations, restructurings or other unusual events, that are expected to affect a particular issuer. There is a risk that the anticipated change or event might not occur, which could cause the price of the security to fall, perhaps sharply. In that case, the investment might not produce the expected gains or might cause a loss. This is an aggressive investment technique that may be considered speculative.

Derivative Investments. The Fund can invest in “derivative” instruments. A derivative is an instrument whose value depends on (or is derived from) the value of an underlying security, asset, interest rate, index or currency. Derivatives may allow the Fund to increase or decrease its exposure to certain markets or risks.

The Fund may use derivatives to seek to increase its investment return or for hedging purposes. The Fund is not required to use derivatives in seeking its investment objective or for hedging and might not do so.

Options, futures and forward contracts are some of the types of derivatives that the Fund can use.. The Fund may also use other types of derivatives that are consistent with its investment strategies or for hedging purposes.

Hedging. Hedging transactions are intended to reduce the risks of securities in the Fund’s portfolio. At times, however, a hedging instrument’s value might not be correlated with the investment it is intended to hedge, and the hedge might be unsuccessful. If the Fund uses a hedging instrument at the wrong time or judges market conditions incorrectly, the strategy could reduce its return or create a loss.

Risks of Derivative Investments. Derivatives may be volatile and may involve significant risks. The underlying security, obligor or other instrument on which a derivative is based, or the derivative itself, may not perform as expected. For some derivatives, it is possible to lose more than the amount invested in the derivative investment. In addition, some derivatives have the potential for unlimited loss, regardless of the size of the Fund’s initial investment. Certain derivative investments held by the Fund may be illiquid, making it difficult to close out an unfavorable position. Derivative transactions may require the payment of premiums and may increase portfolio turnover. Derivatives are subject to credit risk, since the Fund may lose money on a derivative investment if the issuer or counterparty fails to pay the amount due. 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. As a result of these risks, the Fund could realize little or no income or lose money from the investment, or the use of a derivative for hedging might be unsuccessful.

In addition, pursuant to rules implemented under financial reform legislation, certain over-the-counter derivatives, including certain interest rate swaps and certain credit default swaps, are required to be executed on a regulated market and/or cleared through a clearinghouse, which may result in increased margin requirements and costs for the Fund. Entering into a derivative transaction that is cleared may entail further risks and

costs, including the counterparty risk of the clearinghouse and the futures commission merchant through which the Fund accesses the clearinghouse.

Illiquid and Restricted Investments. Investments that do not have an active trading market, or that have legal or contractual limitations on their resale, may be considered to be “illiquid” investments. Illiquid investments may be difficult to value or to sell promptly at an acceptable price or may require registration under applicable securities laws before they can be sold publicly. Investments that have limitations on their resale are referred to as “restricted investments.” Certain restricted investments that are eligible for resale to qualified institutional purchasers may not be regarded as illiquid.

The Fund will comply with Rule 22e-4 under the Investment Company Act of 1940 in managing its illiquid investments. The Fund’s holdings of illiquid investments are monitored on an ongoing basis to determine whether to sell any of those investments to maintain adequate liquidity.

Additional Investment Information. In anticipation of or in response to market, economic, political, or other conditions, the Fund’s portfolio manager may temporarily use a different investment strategy for defensive purposes. If the Fund’s portfolio manager does 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.

12 Invesco Developing Markets Fund

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 October 31, 2020, the Adviser received compensation of 0.75% of the Fund's average daily net assets, after fee waiver and/or expense reimbursement, 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.

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.

■

Individual Retirement Accounts (IRAs) include Traditional and Roth IRAs.

To access your account, go to the tab for “Account access,” then click on “Account Access” under “Accounts & Services.” 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, CX and RX Shares

Class AX, CX and RX shares are closed to new investors. Only investors who have continuously maintained an account in Class AX, CX or RX of a specific Fund may make additional purchases into Class AX, CX and RX, 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), CX, or RX 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

A-2 The Invesco Funds

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 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.

■

Invesco Premier Tax-Exempt 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

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

Investors who own Investor Class shares of a Fund, who purchase Class A shares of a different Fund through the same account in which the Investor Class Shares were first purchased.

Funds of funds or other pooled investment vehicles.

Former shareholders of Atlas Strategic Income Fund who purchase shares of a Fund into which shareholders of Invesco Global Strategic Income Fund may exchange if permitted by the intermediary’s policies.

■

Former shareholders of Oppenheimer Total Return Fund Periodic Investment Plan who purchase shares of a Fund into which shareholders of Invesco Main Street Fund may exchange if permitted by the intermediary’s policies.

In addition, investors may acquire Class A shares without paying an initial sales charge in connection with:

■

reinvesting dividends and distributions;

■

exchanging shares of one Fund that were previously assessed a sales charge for shares of another Fund;

■

purchasing shares in connection with the repayment of an Employer Sponsored Retirement and Benefit Plan loan administered by the Funds’ transfer agent; and

Edward D. Jones & Co., L.P. (“Edward Jones”)

Policies Regarding Transactions Through Edward Jones

The following information has been provided by Edward Jones:

The following information supersedes prior information with respect to transactions and positions held in fund shares through an Edward Jones system. Shareholders purchasing Fund shares through the Edward Jones commission and fee-based platforms will be eligible for the following load waivers (front- end sales charge waivers and contingent deferred, or back-end, sales charge waivers) and discounts, which may differ from those disclosed elsewhere in this Fund's prospectus or statement of additional information (“SAI”). In all instances, it is the shareholder's responsibility to inform Edward Jones at the time of purchase of any relationship, holdings of Invesco Funds, or other facts qualifying the purchaser for discounts or waivers. Edward Jones can ask for documentation of such circumstance. Shareholders should contact Edward Jones if they have questions regarding their eligibility for these discounts and waivers.

■

Front-end sales load waivers on Class A shares available at Edward Jones

■

Associates of Edward Jones and its affiliates and their family members who are in the same pricing group (as determined by Edward Jones under its policies and procedures) as the associate. This waiver will continue for the remainder of the associate's life if the associate retires from Edward Jones in good-standing and remains in good standing pursuant to Edward Jones' policies and procedures.

■

Shares purchased in an Edward Jones fee-based program.

■

Shares purchased through reinvestment of capital gains distributions and dividend reinvestment.

■

Shares purchased from the proceeds of redeemed shares of the same fund family so long as the following conditions are met: 1) the proceeds are from the sale of shares within 60 days of the purchase, and 2) the sale and purchase are made in the same share class and the same account or the purchase is made in an individual retirement account with proceeds from liquidations in a non-retirement account.

■

Shares exchanged into Class A shares from another share class so long as the exchange is into the same fund and was initiated at the discretion of Edward Jones. Edward Jones is responsible for any remaining CDSC due to the fund company, if applicable. Any future purchases are subject to the applicable sales charge as disclosed in the prospectus.

■

Exchanges from Class C shares to Class A shares of the same fund, generally, in the 84th month following the anniversary of the purchase date or earlier at the discretion of Edward Jones.

■

CDSC Waivers on Classes A and C shares available at Edward Jones

■

■

Systematic withdrawals with up to 10% per year of the account value.

■

Front-end load discounts available at Edward Jones: Breakpoints, Rights of Accumulation & Letters of Intent

■

Breakpoint pricing, otherwise known as volume pricing, at dollar thresholds as described in the prospectus.

■

Rights of Accumulation (“ROA”) which entitles the shareholder to the applicable sales charge on a purchase of Class A shares will be determined by taking into account all share classes (except certain money market funds and any assets held in group retirement plans) of Invesco Funds held by the shareholder or in an account grouped by Edward Jones with other accounts for the purpose of providing certain pricing considerations (“pricing groups”). If grouping assets as a shareholder, this includes all share classes held on the Edward Jones platform and/or held on another platform. The inclusion of eligible fund family assets in the ROA calculation is dependent on the shareholder notifying Edward Jones of such assets at the time of calculation. Money market funds are included only if such shares were sold with a sales charge at the time of purchase or acquired in exchange for shares purchased with a sales charge.

■

The employer maintaining a SEP IRA plan and/or SIMPLE IRA plan may elect to establish or change ROA for the IRA accounts associated with the plan to a plan-level grouping as opposed to including all share classes at a shareholder or pricing group level.

■

ROA is determined by calculating the higher of cost minus redemptions or market value (current shares x NAV).

■

Letters of Intent (“LOI”) allow shareholders to receive sales charge and breakpoint discounts for purchases shareholders intend to make over a 13- month period from the date Edward Jones receives the LOI. The LOI is determined by calculating the higher of cost or market value of qualifying holdings at LOI initiation in combination with the value that the shareholder intends to buy over a 13-month period to calculate the front-end sales charge and any breakpoint discounts. Each purchase the shareholder makes during that 13-month period will receive the sales charge and breakpoint discount that applies to the total amount. The inclusion of eligible fund family assets in the LOI calculation is dependent on the shareholder notifying Edward Jones of such assets at the time of calculation. Purchases made before the LOI is received by Edward Jones are not adjusted under the LOI and will not reduce the sales charge previously paid. Sales charges will be adjusted if LOI is not met.

■

If the employer maintaining a SEP IRA plan and/or SIMPLE IRA plan has elected to establish or change ROA for the IRA accounts associated with the plan to a plan-level grouping, LOIs will also be at the plan-level and may only be established by the employer.

Qualifying for Reduced Sales Charges and Sales Charge Exceptions

The following types of accounts qualify for reduced sales charges or sales charge exceptions under ROAs and LOIs:

an individual account owner;

immediate family of the individual account owner (which includes the individual’s spouse or domestic partner; the individual’s children, step-children or grandchildren; the spouse or domestic partner of the individual’s children, step-children or grandchildren; the individual’s parents and step-parents; the parents or step-parents of the individual’s spouse or domestic partner; the individual’s grandparents; and the individual’s siblings);

a Retirement and Benefit Plan so long as the plan is established exclusively for the benefit of an individual account owner; and

a Coverdell Education Savings Account (Coverdell ESA), maintained

pursuant to Section 530 of the Code (in either case, the account must be established by an individual account owner or have an individual account owner named as the beneficiary thereof).

Alternatively, an Employer Sponsored Retirement and Benefit Plan (but not including plans utilizing the Invesco 403(b)(7) Custodial Account program, or the individual custodial accounts thereunder) or Employer Sponsored IRA may be eligible to purchase shares pursuant to a ROA at the plan level, and receive a reduced applicable initial sales charge for a new purchase based on the total value of the current purchase and the value of other shares owned by the plan’s participants if:

the employer or plan sponsor submits all contributions for all participating employees in a single contribution transmittal (the Invesco Funds will not accept separate contributions submitted with respect to individual participants);

each transmittal is accompanied by checks or wire transfers; and

if the Invesco Funds are expected to carry separate accounts in the names of each of the plan participants, (i) the employer or plan sponsor notifies Invesco Distributors or its designee in writing that the separate accounts of all plan participants should be linked, and (ii) all new participant accounts are established by submitting an appropriate Account Application on behalf of each new participant with the contribution transmittal.

Participant accounts in a retirement plan that are eligible to purchase shares pursuant to a ROA at the plan level may not also be considered eligible to do so for the benefit of an individual account owner.

In all instances, it is the purchaser’s responsibility to notify Invesco Distributors or its designee of any relationship or other facts qualifying the purchaser as eligible for reduced sales charges and/or sales charge exceptions and to provide all necessary documentation of such facts in order to qualify for reduced sales charges or sales charge exceptions. For additional information on linking accounts to qualify for ROA or LOI, please see the Funds’ SAI.

Purchases of Class A shares of Invesco Conservative Income Fund, Invesco Government Money Market Fund and Invesco Short Term Municipal Fund, Class AX shares or Invesco Cash Reserve Shares of Invesco Government Money Market Fund and Invesco U.S. Government Money Portfolio, as applicable, or Investor Class shares of any Fund will not be taken into account in determining whether a purchase qualifies for a reduction in initial sales charges pursuant to ROAs or LOIs.

Rights of Accumulation

Purchasers that qualify for ROA may combine new purchases of Class A shares of a Fund with shares of the Fund or other open-end Invesco Funds currently owned (Class A, C, IB, IC, P, R, S or Y) for the purpose of qualifying for the lower initial sales charge rates that apply to larger purchases. The applicable initial sales charge for the new purchase will be based on the total of your current purchase and the value of other shares owned based on their current public offering price. The Funds’ transfer agent may automatically link certain accounts registered in the same name with the same taxpayer identification number for the purpose of qualifying you for lower initial sales charge rates.

Letters of Intent

Under a LOI, you commit to purchase a specified dollar amount of Class A shares of one or more Funds during a 13-month period. The amount you agree to purchase determines the initial sales charge you pay. If the full amount committed to in the LOI is not invested by the end of the 13-month period, your account will generally be assessed the higher initial sales charge that would normally be applicable to the total amount actually invested. Shares equal in value to 5% of the intended purchase amount will be held in escrow for this purpose.

Reinstatement Following Redemption

If you redeem any class of shares of a Fund, you may reinvest all or a portion of the proceeds from the redemption (and may include that amount necessary to acquire a fractional Share to round off his or her purchase to the next full Share) in the same share class of any Fund within 180 days of

A-9 The Invesco Funds

the redemption without paying an initial sales charge. Class P, S, and Y redemptions may be reinvested into Class A shares without an initial sales charge.

This reinstatement privilege does not apply to a purchase made through a regularly scheduled automatic investment plan, such as a purchase by a regularly scheduled payroll deduction or transfer from a bank account.

This reinstatement privilege shall be suspended for the period of time in which a purchase block is in place on a shareholder’s account. Please see “Purchase Blocking Policy” discussed below.

In order to take advantage of this reinstatement privilege, you must inform your financial adviser or the Funds’ transfer agent that you wish to do so at the time of your reinvestment.

Contingent Deferred Sales Charges (CDSCs)

CDSCs on Class A Shares and Invesco Cash Reserve Shares

Any shares of a Large Purchase of Class A shares redeemed prior to 18 months after the date of purchase will be subject to a CDSC of 1% with the exception of Class A shares of Invesco Conservative Income Fund and Invesco Short Term Municipal Fund which do not have CDSCs on redemptions.

If Invesco Distributors pays a concession to a financial intermediary in connection with a Large Purchase of Class A shares by an Employer Sponsored Retirement and Benefit Plan or SIMPLE IRA Plan, the Class A shares will be subject to a 1% CDSC if all of the Employer Sponsored Retirement and Benefit Plan’s or SIMPLE IRA’s shares are redeemed within one year from the date of initial purchase.

If you acquire Invesco Cash Reserve Shares or Class A shares of Invesco Government Money Market Fund or Invesco Cash Reserve Shares of Invesco U.S. Government Money Portfolio through an exchange involving Class A shares that were subject to a CDSC, the shares acquired as a result of the exchange will continue to be subject to that same CDSC.

CDSCs on Class C Shares

Class C shares are subject to a CDSC. If you redeem your shares during the first year since your purchase has been made you will be assessed a 1% CDSC, unless you qualify for one of the CDSC exceptions outlined below.

CDSCs on Class C Shares – Employer Sponsored Retirement and Benefit Plans and Employer Sponsored IRAs

Class C shares are subject to a 1.00% CDSC at the time of redemption if all of the Employer Sponsored Retirement and Benefit Plan’s or Employer Sponsored IRA’s shares are redeemed within one year from the date of initial purchase.

CDSCs on Class C Shares of Invesco Short Term Bond Fund

While Class C shares of Invesco Short Term Bond Fund are not subject to a CDSC, if you acquired shares of Invesco Short Term Bond Fund through an exchange, and the shares originally purchased were subject to a CDSC, the shares acquired as a result of the exchange will continue to be subject to that same CDSC. Conversely, if you acquire Class C shares of any other Fund as a result of an exchange involving Class C shares of Invesco Short Term Bond Fund that were not subject to a CDSC, then the shares acquired as a result of the exchange will not be subject to a CDSC.

Computing a CDSC

The CDSC on redemptions of shares is computed based on the lower of their original purchase price or current net asset value, net of reinvested dividends and capital gains distributions. In determining whether to charge a CDSC, shares are accounted for on a first-in, first-out basis, which means that you will redeem shares on which there is no CDSC first, and then shares in the order of their purchase.

CDSC Exceptions

Investors who own shares that are otherwise subject to a CDSC will not pay a CDSC in the following circumstances:

■

If you participate in the Systematic Redemption Plan and withdraw up to 12% of the value of your shares that are subject to a CDSC in any twelve-month period.

■

If you redeem shares to pay account fees.

■

If you are the executor, administrator or beneficiary of an estate or are otherwise entitled to assets remaining in an account following the death or post-purchase disability of a shareholder or beneficial owner and you choose to redeem those shares.

There are other circumstances under which you may be able to redeem shares without paying CDSCs. For additional information about such circumstances, please see the Appendix entitled “Purchase, Redemption and Pricing of Shares” in each Fund’s SAI.

Shares acquired through the reinvestment of dividends and distributions are not subject to CDSCs.

The following share classes are sold without a CDSC:

■

Class C shares of Invesco Short Term Bond Fund

■

Class A2 shares of Invesco Short Duration Inflation Protected Fund and Invesco Limited Term Municipal Income Fund

A-10 The Invesco Funds

reasonably designed to limit all beneficial owners of the Fund to natural persons, and investments in the Fund are limited to accounts beneficially owned by natural persons. Natural persons may invest in the Fund through certain tax-advantaged savings accounts, trusts and other retirement and investment accounts, which may include, among others: participant-directed defined contribution plans; individual retirement accounts; simplified employee pension arrangements; simple retirement accounts; custodial accounts; deferred compensation plans for government or tax-exempt organization employees; Archer medical savings accounts; college savings plans; health savings account plans; ordinary trusts and estates of natural persons; or certain other retirement and investment accounts with ultimate investment authority held by the natural person beneficial owner, notwithstanding having an institutional decision maker making day-to-day decisions (e.g., a plan sponsor in certain retirement arrangements or an investment adviser managing discretionary investment accounts).

Further, financial intermediaries may only submit purchase orders if they have implemented policies and procedures reasonably designed to limit all investors on behalf of whom they submit orders to accounts beneficially owned by natural persons. Financial intermediaries may be required to provide a written statement or other representation that they have in place, and operate in compliance with, such policies and procedures prior to submitting purchase orders. Such policies and procedures may include provisions for the financial intermediary to promptly report to the Fund or the transfer agent the identification of any shareholder of the Fund that does not qualify as a natural person of whom they are aware and promptly take steps to redeem any such shareholder’s shares of the Fund upon request by the Fund or the transfer agent, in such manner as it may reasonably request. The Fund may involuntarily redeem any such shareholder who does not voluntarily redeem their shares.

IRAs and Employer Sponsored IRAs are also not eligible for Class R5 shares. If you hold your shares through a financial intermediary, the terms by which you purchase, redeem and exchange shares may differ than the terms in this prospectus depending upon the policies and procedures of your financial intermediary. Notwithstanding the foregoing, each shareholder must still meet the Fund’s eligibility requirements applicable to the share class to be purchased.

Purchase orders will not be processed unless the account application and purchase payment are received in good order. In accordance with the USA PATRIOT Act, if you fail to provide all the required information requested in the current account application, your purchase order will not be processed. Additionally, federal law requires that the Funds verify and record your identifying information.

Systematic Purchase Plan (Available for all classes except Class R5 and R6 shares)

You can arrange for periodic investments in any of the Funds by authorizing the Funds’ transfer agent to withdraw the amount of your investment from your bank account on a day or dates you specify and in an amount of at least $25 per Fund for IRAs and Coverdell ESAs, and at least $50 per Fund for all other types of accounts (a Systematic Purchase Plan). You may stop the Systematic Purchase Plan at any time by giving the Funds’ transfer agent notice ten days prior to your next scheduled withdrawal. Certain financial advisers and other financial intermediaries may also offer systematic purchase plans.

Dollar Cost Averaging (Available for all classes except Class R5 and R6 shares)

Dollar Cost Averaging allows you to make automatic periodic exchanges, if permitted, from one Fund to another Fund or multiple other Funds. The account from which exchanges are to be made must have a minimum balance of $5,000 before you can use this option. Exchanges will occur on (or about) the day of the month you specify, in the amount you specify. Dollar Cost Averaging cannot be set up for the 29th through the 31st of the month. The minimum amount you can exchange to another Fund is $50. Your financial intermediary may offer alternative dollar cost averaging programs with different requirements.

Automatic Dividend and Distribution Investment

Your dividends and distributions may be paid in cash or reinvested in the same Fund or another Fund without paying an initial sales charge.

Unless you specify otherwise, your dividends and distributions will automatically be reinvested in the same Fund. You must comply with the following requirements to be eligible to invest your dividends and distributions in shares of another Fund:

■

Your account balance in the Fund paying the dividend or distribution must be at least $5,000; and

■

Your account balance in the Fund receiving the dividend or distribution must be at least $500.

If you elect to receive your distributions by check, and the distribution amount is $25 or less, then the amount will be automatically reinvested in the same Fund and no check will be issued. If you have elected to receive distributions by check, and the postal service is unable to deliver checks to your address of record, then your distribution election may be converted to having all subsequent distributions reinvested in the same Fund and no checks will be issued. With respect to certain account types, if your check remains uncashed for six months, the Fund generally reserves the right to reinvest your distribution check in your account at the then applicable NAV and to reinvest all subsequent distributions in shares of the Fund. Such checks will be reinvested into the same share class of the Fund. You should contact the Funds’ transfer agent to change your distribution option, and your request to do so must be received by the Funds’ transfer agent before the record date for a distribution in order to be effective for that distribution. No interest will accrue on amounts represented by uncashed distribution checks.

Redeeming Shares*

The Funds’ transfer agent or authorized intermediary, if applicable, must receive your call before the Funds’ net asset value determination (as defined by the applicable Fund) in order to effect the redemption at that day’s net asset value.

Your broker or financial intermediary may charge service fees for handling redemption transactions.

*Class R5 and R6 shares may only be redeemed through a financial intermediary or by telephone at (800) 959-4246.

Timing and Method of Payment

The Funds’ transfer agent typically expects to pay redemption proceeds to redeeming shareholders within one business day after a redemption request is received in good order, regardless of the method a Fund uses to make such payment. However, a Fund may take up to seven days to process a redemption request. “Good order” means that all necessary information and documentation related to the redemption request have been provided to the Funds’ transfer agent or authorized intermediary, if applicable. If your request is not in good order, the Funds’ transfer agent may require additional documentation in order to redeem your shares. If you redeem shares recently purchased by check or ACH, you may be required to wait up to ten calendar days before your redemption proceeds are sent. This delay is necessary to ensure that the purchase has cleared. You can avoid the check hold period if you pay for your shares with a certified check, a cashier’s check or a federal wire. Payment may be postponed under unusual circumstances, as allowed by the SEC, such as when the NYSE restricts or suspends trading.

In addition, a temporary hold may be placed on the disbursement of redemption proceeds from an account if there is a reasonable belief that financial exploitation of a Specified Adult (as defined below) has occurred, is occurring, has been attempted, or will be attempted. Notice of such a delay will be provided in accordance with regulatory requirements. This temporary hold will be for an initial period of no more than 15 business days while an internal review is performed. Should the internal review support the belief that financial exploitation has occurred, is occurring, has been attempted or will be attempted, the temporary hold may be extended for up to 10 additional business days. Both the initial and subsequent hold on the disbursement may be terminated or extended by a state regulator or an agency or court of competent jurisdiction. For purposes of this paragraph, the term “Specified Adult” refers to an individual who is (a) a natural person age 65 and older, or (b) a natural person age 18 and older who is reasonably believed to have a mental or physical impairment that renders the individual unable to protect his or her own interests.

If you redeem by telephone, the Funds’ transfer agent will transmit the amount of redemption proceeds electronically to your pre-authorized bank account. Redemption checks are mailed to your address of record, via first

class U.S. mail, unless you make other arrangements with the Funds’ transfer agent.

The Funds’ transfer agent uses reasonable procedures to confirm that instructions communicated via telephone and the Internet are genuine, and the Funds and the Funds’ transfer agent are not liable for losses arising from actions taken in accordance with instructions that are reasonably believed to be genuine.

A Fund typically expects to use holdings of cash and cash equivalents and sales of portfolio assets to meet redemption requests, both regularly and in stressed market conditions. The Funds also have the ability to redeem in kind as further described below under “Redemptions in Kind.” Invesco Floating Rate ESG Fund has a revolving line of credit that may be used to meet redemptions in stressed market conditions.

Expedited Redemptions (for Invesco Cash Reserve Shares of Invesco Government Money Market Fund and Invesco U.S. Government Money Portfolio only)

If you place your redemption order by telephone, before 11:30 a.m. Eastern Time and request an expedited redemption, the Funds’ transfer agent will transmit payment of redemption proceeds on that same day via federal wire to a bank of record on your account. If the Funds’ transfer agent receives your redemption order after 11:30 a.m. Eastern Time and before the close of the customary trading session of the NYSE, it will transmit payment on the next business day.

Suspension of Redemptions

The right of redemption may be suspended or the date of payment postponed when (a) trading on the NYSE is restricted, as determined by applicable rules and regulations of the SEC, (b) the NYSE is closed for other than customary weekend and holiday closings, (c) the SEC has by order permitted such suspension, or (d) an emergency as determined by the SEC exists making disposition of portfolio securities or the valuation of the net assets of the Fund not reasonably practicable. With respect to Invesco Government Money Market Fund, Invesco U.S. Government Money Portfolio, Invesco Premier Portfolio, Invesco Premier Tax-Exempt Portfolio and Invesco Premier U.S. Government Money Portfolio, in the event that the Fund, at the end of a business day, has invested less than 10% of its total assets in weekly liquid assets or, with respect to the retail and government money market funds, the Fund’s price per share as computed for the purpose of distribution, redemption and repurchase, rounded to the nearest 1%, has deviated from the stable price established by the Fund’s Board of Trustees (“Board”) or the Board, including a majority of trustees who are not interested persons as defined in the 1940 Act, determines that such a deviation is likely to occur, and the Board, including a majority of trustees who are not interested persons of the Fund, irrevocably has approved the liquidation of the Fund, the Fund’s Board has the authority to suspend redemptions of Fund shares.

Liquidity Fees and Redemption Gates

For Invesco Premier Portfolio and Invesco Premier Tax-Exempt Portfolio, if the Fund’s weekly liquid assets fall below 30% of its total assets, the Board, in its discretion, may impose liquidity fees of up to 2% of the value of the shares redeemed and/or suspend redemptions (redemption gates). In addition, if any such Fund’s weekly liquid assets falls below 10% of its total assets at the end of any business day, the Fund must impose a 1% liquidity fee on shareholder redemptions unless the Board determines that not doing so is in the best interests of the Fund.

Liquidity fees and redemption gates are most likely to be imposed, if at all, during times of extraordinary market stress. In the event that a liquidity fee or redemption gate is imposed, the Board expects that for the duration of its implementation and the day after which such gate or fee is terminated, the Fund would strike only one net asset value per day, at the Fund’s last scheduled net asset value calculation time.

The imposition and termination of a liquidity fee or redemption gate will be reported by a Fund to the SEC on Form N-CR. Such information will also be available on the Fund’s website. In addition, a Fund will communicate such action through a supplement to its registration statement and may further communicate such action through a press release or by other

A-13 The Invesco Funds

means. If a liquidity fee is applied by the Board, it will be charged on all redemption orders submitted after the effective time of the imposition of the fee by the Board. Liquidity fees would reduce the amount you receive upon redemption of your shares. In the event a Fund imposes a redemption gate, the Fund or any financial intermediary on its behalf will not accept redemption requests until the Fund provides notice that the redemption gate has been terminated.

Redemption requests submitted while a redemption gate is imposed will be cancelled without further notice. If shareholders still wish to redeem their shares after a redemption gate has been lifted, they will need to submit a new redemption request.

Liquidity fees and redemption gates will generally be used to assist a Fund to help preserve its market–based NAV per share. It is possible that a liquidity fee will be returned to shareholders in the form of a distribution. The Board may, in its discretion, terminate a liquidity fee or redemption gate at any time if it believes such action to be in the best interest of a Fund. Also, liquidity fees and redemption gates will automatically terminate at the beginning of the next business day once a Fund’s weekly liquid assets reach at least 30% of its total assets. Redemption gates may only last up to 10 business days in any 90-day period. When a fee or a gate is in place, the Fund may elect not to permit the purchase of shares or to subject the purchase of shares to certain conditions, which may include affirmation of the purchaser’s knowledge that a fee or a gate is in effect. When a fee or a gate is in place, shareholders will not be permitted to exchange into or out of a Fund.

There is some degree of uncertainty with respect to the tax treatment of liquidity fees received by a Fund, and such tax treatment may be the subject to future IRS guidance. If a Fund receives liquidity fees, it will consider the appropriate tax treatment of such fees to the Fund at such time.

Financial intermediaries are required to promptly take the steps requested by the Funds or their designees to impose or help to implement a liquidity fee or redemption gate as requested from time to time, including the rejection of orders due to the imposition of a fee or gate or the prompt re-confirmation of orders following a notification regarding the implementation of a fee or gate. If a liquidity fee is imposed, these steps are expected to include the submission of separate, rather than combined, purchase and redemption orders from the time of the effectiveness of the liquidity fee or redemption gate and the submission of such order information to the Fund or its designee prior to the next calculation of a Fund’s net asset value. Unless otherwise agreed to between a Fund and financial intermediary, the Fund will withhold liquidity fees on behalf of financial intermediaries. With regard to such orders, a redemption request that a Fund determines in its sole discretion has been received in good order by the Fund or its designated agent prior to the imposition of a liquidity fee or redemption gate may be paid by the Fund despite the imposition of a redemption gate or without the deduction of a liquidity fee. If a liquidity fee is imposed during the day, an intermediary who receives both purchase and redemption orders from a single account holder is not required to net the purchase and redemption orders. However, the intermediary is permitted to apply the liquidity fee to the net amount of redemptions (even if the purchase order was received prior to the time the liquidity fee was imposed).

Where a Financial Intermediary serves as a Fund’s agent for the purpose of receiving orders, trades that are not transmitted to the Fund by the Financial Intermediary before the time required by the Fund or the transfer agent may, in the Fund’s discretion, be processed on an as-of basis, and any cost or loss to the Fund or transfer agent or their affiliates, from such transactions shall be borne exclusively by the Financial Intermediary.

Systematic Withdrawals (Available for all classes except Class R5 and R6 shares)

You may arrange for regular periodic withdrawals from your account in amounts equal to or greater than $50 per Fund. The Funds’ transfer agent will redeem the appropriate number of shares from your account to provide redemption proceeds in the amount requested. You must have a total account balance of at least $5,000 in order to establish a Systematic

Redemption Plan, unless you are establishing a Required Minimum Distribution for a Retirement and Benefit Plan. You can stop this plan at any time by giving ten days’ prior notice to the Funds’ transfer agent.

Check Writing

The Funds’ transfer agent provides check writing privileges for accounts in the following Funds and share classes:

■

Invesco Government Money Market Fund, Invesco Cash Reserve Shares, Class AX shares, Class Y shares and Investor Class shares

■

Invesco U.S. Government Money Portfolio, Invesco Cash Reserve Shares and Class Y shares

■

Invesco Premier Portfolio, Investor Class shares

■

Invesco Premier Tax-Exempt Portfolio, Investor Class shares

■

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

You may redeem shares of these Funds by writing checks in amounts of $250 or more if you have subscribed to the service by completing a Check Writing authorization form.

Check writing privileges are not available for Retirement and Benefit Plans. Checks are not eligible to be converted to ACH by the payee. You may not give authorization to a payee by phone to debit your account by ACH for a debt owed to the payee.

If you do not have a sufficient number of shares in your account to cover the amount of the check and any applicable deferred sales charge, the check will be returned and no shares will be redeemed. Because it is not possible to determine your account’s value in advance, you should not write a check for the entire value of your account or try to close your account by writing a check.

A check writing redemption request which is verifiably submitted to a Fund’s agent before a liquidity fee or redemption gate is imposed will be considered a valid redemption and will be processed normally.

Signature Guarantees

The Funds’ transfer agent requires a signature guarantee in the following circumstances:

■

When your redemption proceeds exceed $250,000 per Fund.

■

When you request that redemption proceeds be paid to someone other than the registered owner of the account.

■

When you request that redemption proceeds be sent somewhere other than the address of record or bank of record on the account.

■

When you request that redemption proceeds be sent to a new address or an address that changed in the last 15 days.

The Funds’ transfer agent will accept a guarantee of your signature by a number of different types of financial institutions. Call the Funds’ transfer agent for additional information. Some institutions have transaction amount maximums for these guarantees. Please check with the guarantor institution to determine whether the signature guarantee offered will be sufficient to cover the value of your transaction request.

Redemptions in Kind

Although the Funds generally intend to pay redemption proceeds solely in cash, the Funds reserve the right to determine, in their sole discretion, whether to satisfy redemption requests by making payment in securities or other property (known as a redemption in kind). Redemptions in kind may result in transaction costs and/or market fluctuations associated with liquidating or holding the securities, respectively.

Purchases-in-Kind

You may purchase shares of a Fund by transferring securities to a Fund in exchange for Fund shares (“in-kind purchases”). In-kind purchases may be made only upon the Funds’ approval and determination that the securities are acceptable investments for the Fund and are purchased consistent with the Fund’s procedures relating to in-kind purchases. The Funds reserve the right to amend or terminate this practice at any time. You must call the Funds at (800) 959-4246 before sending any securities. Please see the SAI for additional details.

Redemptions by Large Shareholders

At times, the Fund may experience adverse effects when certain large shareholders redeem large amounts of shares of the Fund. Large

A-14 The Invesco Funds

redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so. In addition, these transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains and may also increase transaction costs and/or increase in the Fund’s expense ratio. When experiencing a redemption by a large shareholder, the Fund may delay payment of the redemption request up to seven days to provide the investment manager with time to determine if the Fund can redeem the request-in-kind or to consider other alternatives to lessen the harm to remaining shareholders. Under certain circumstances, however, the Fund may be unable to delay a redemption request, which could result in the automatic processing of a large redemption that is detrimental to the Fund and its remaining shareholders.

Redemptions Initiated by the Funds

If your account (Class A, C, P, S and Investor Class shares only) has been open at least one year, you have not made an additional purchase in the account during the past six calendar months, and the value of your account falls below $500 for three consecutive months, the Funds have the right to redeem the account after giving you 60 days’ prior written notice. You may avoid having your account redeemed during the notice period by bringing the account value up to $500 or by initiating a Systematic Purchase Plan.

A financial intermediary may have a different policy regarding redemptions of accounts with small balances. The Fund is not responsible for any small account balance policies imposed by financial intermediaries or for notifying shareholders of any changes to them. See “Waivers Available Through Certain Financial Intermediaries and Other Financial Intermediary-Specific Arrangements” for more information on certain intermediary-specific small account balance policies. Please consult with your financial intermediary if you have any questions regarding their policies.

If a Fund determines that you have not provided a correct Social Security or other tax identification number on your account application, or the Fund is not able to verify your identity as required by law, the Fund may, at its discretion, redeem the account and distribute the proceeds to you.

In order to separate retail investors (natural persons) and non-retail investors, the Invesco Premier Portfolio reserve the right to redeem shares in any account that the Funds cannot confirm to their satisfaction are beneficially owned by natural persons. The Funds will provide advance written notice of their intent to make any such involuntary redemptions. The Funds reserve the right to redeem shares in any account that they cannot confirm to their satisfaction are beneficially owned by natural persons, after providing advance notice.

Neither a Fund nor its investment adviser will be responsible for any loss in an investor’s account or tax liability resulting from an involuntary redemption.

Minimum Account Balance (Available for all classes except Class R5 and R6 shares)

A low balance fee of $12 per year may be deducted in the fourth quarter of each year from all accounts held in the Funds (each a Fund Account) with a value less than the low balance amount (the Low Balance Amount) as determined from time to time by the Funds and the Adviser. The Funds and the Adviser generally expect the Low Balance Amount to be $750, but such amount may be adjusted for any year depending on various factors, including market conditions. The Low Balance Amount and the date on which it will be deducted from any Fund Account will be posted on our website, www.invesco.com/us, on or about November 1 of each year. This fee will be payable to the Funds’ transfer agent by redeeming from a Fund Account sufficient shares owned by a shareholder and will be used by the Funds’ transfer agent to offset amounts that would otherwise be payable by the Funds to the Funds’ transfer agent under the Funds’ transfer agency agreement with the Funds’ transfer agent. The low balance fee does not apply to participant accounts in advisory programs or to Employer Sponsored Retirement and Benefit Plans.

Exchanging Shares

You may, under certain circumstances, exchange shares in one Fund for those of another Fund. An exchange is the purchase of shares in one Fund which is paid for with the proceeds from a redemption of shares of another Fund effectuated on the same day. Any gain on the transaction may be subject to federal income tax. Accordingly, the procedures and processes applicable to redemptions of Fund shares, as discussed under the heading “Redeeming Shares” above, will apply. Before requesting an exchange, review the prospectus of the Fund you wish to acquire.

All exchanges are subject to the limitations set forth in the prospectuses of the Funds. If you wish to exchange shares of one Fund for those of another Fund, you must consult the prospectus of the Fund whose shares you wish to acquire to determine whether the Fund is offering shares to new investors and whether you are eligible to acquire shares of that Fund.

Permitted Exchanges

Except as otherwise provided herein or in the SAI, you generally may exchange your shares for shares of the same class of another Fund. The following table shows generally permitted exchanges from one Fund to another Fund (exceptions listed below under “Exchanges Not Permitted”):

Exchange From	Exchange To
Invesco Cash Reserve Shares	Class A, C, R, Investor Class

Exchanges into Invesco Senior Loan Fund

Invesco Senior Loan Fund is a closed-end interval fund that continuously offers its shares pursuant to the terms and conditions of its prospectus. The Adviser is the investment adviser for the Invesco Senior Loan Fund. As with the Invesco Funds, you generally may exchange your shares of Class A (Invesco Cash Reserve Shares of Invesco Government Money Market Fund and Invesco U.S. Government Money Portfolio) or Class C of any Invesco Fund for shares of Class A or Class C, respectively, of Invesco Senior Loan Fund. Please refer to the prospectus for the Invesco Senior Loan Fund for more information, including limitations on exchanges out of Invesco Senior Loan Fund.

Exchanges Not Permitted

The following exchanges are not permitted:

■

Investor Class shares cannot be exchanged for Class A shares of any Fund which offers Investor Class shares.

■

Class A2 shares of Invesco Short Duration Inflation Protected Fund and Invesco Limited Term Municipal Income Fund cannot be exchanged for Class A shares of those Funds.

■

Invesco Cash Reserve Shares cannot be exchanged for Class C or R shares if the shares being exchanged were acquired by exchange from Class A shares of any Fund.

■

All existing systematic exchanges and reallocations will cease and these options will no longer be available on all 403(b) prototype plans.

A-15 The Invesco Funds

■

Class A, C or R shares of a Fund acquired by exchange of Class Y shares of Invesco U.S. Government Money Portfolio cannot be exchanged for Class Y shares of any Fund, except Class Y shares of Invesco U.S. Government Money Portfolio.

Exchange Conditions

Shares must have been held for at least one day prior to the exchange with the exception of dividends and distributions that are reinvested.

Under unusual market conditions, a Fund may delay the exchange of shares for up to five business days if it determines that it would be materially disadvantaged by the immediate transfer of exchange proceeds. The exchange privilege is not an option or right to purchase shares. Any of the participating Funds or the distributor may modify or terminate this privilege at any time.

Initial Sales Charges, CDSCs and 12b-1 Fees on Applicable to Exchanges

You may be required to pay an initial sales charge when exchanging from a Fund with a lower initial sales charge than the one into which you are exchanging. If you exchange into shares that are subject to a CDSC, the Funds’ transfer agent will begin the holding period for purposes of calculating the CDSC on the date you made your initial purchase.

In addition, as a result of differences in the forms of distribution plans among the Funds, certain exchanges of Class A shares, Class C shares, and Class R shares of a Fund for the same class of shares of another Fund may result in investors paying a higher or a lower 12b-1 fee on the Fund being exchanged into. Please refer to the prospectus fee table and financial highlights table and the SAI for more information on the fees and expenses, including applicable 12b-1 fees, of the Fund you wish to acquire.

Share Class Conversions

Shares of one class of a Fund may be converted into shares of another class of the same Fund, provided that you are eligible to buy that share class. Investors who hold Fund shares through a financial intermediary that does not have an agreement to make certain share classes of the Funds available or that cannot systematically support the conversion may not be eligible to convert their shares. Furthermore, your financial intermediary may have discretion to effect a conversion on your behalf. Consult with your financial intermediary for details. Any CDSC associated with the converting shares will be assessed immediately prior to the conversion to the new share class. The conversion of shares of one class of a Fund into shares of another class of the same Fund is not taxable for federal income tax purposes and no gain or loss will be reported on the transaction. See the applicable prospectus for share class information.

Fees and expenses differ between share classes. You should read the prospectus for the share class into which you are seeking to convert your shares prior to the conversion.

Automatic Conversion of Class C and Class CX Shares

Class C and Class CX shares held for eight years after purchase are eligible for automatic conversion into Class A and Class AX shares of the same Fund, respectively, except that for the Invesco Government Money Market Fund and Invesco U.S. Government Money Portfolio, the Funds’ Class C and/or Class CX shares would be eligible to automatically convert into the Fund’s Invesco Cash Reserve Share Class (the Conversion Feature). The automatic conversion pursuant to the Conversion Feature will generally occur at the end of the month following the eighth anniversary after a purchase of Class C or Class CX shares (the Conversion Date). The first conversion of Class C and Class CX shares to Class A and Class AX shares under this policy would occur at the end of December 2020 for all Class C and Class CX shares that were held for more than eight years as of November 30, 2020.

Automatic conversions pursuant to the Conversion Feature will be on the basis of the NAV per share, without the imposition of any sales charge (including a CDSC), fee or other charge. All such automatic conversions of Class C and Class CX shares will constitute tax-free exchanges for federal income tax purposes.

Class C and Class CX shares of a Fund acquired through a reinvestment of dividends and distributions will convert to Class A and Class AX shares, respectively, of the Fund (or Invesco Cash Reserve shares for Invesco Government Money Market Fund) on the Conversion Date pro rata with the converting Class C and Class CX shares of that Fund that were not acquired through reinvestment of dividends and distributions.

Class C or Class CX shares held through a financial intermediary in existing omnibus Employer Sponsored Retirement and Benefit Plans and other omnibus accounts may be converted pursuant to the Conversion Feature by the financial intermediary once it is determined that the Class C or Class CX shares have been held for the required holding period. It is the financial intermediary’s (and not the Fund’s) responsibility to keep records and to ensure that the shareholder is credited with the proper holding period as the Fund and its agents may not have transparency into how long a shareholder has held Class C or Class CX shares for purposes of determining whether such Class C or Class CX shares are eligible to automatically convert pursuant to the Conversion Feature. In order to determine eligibility for automatic conversion in these circumstances, it is the responsibility of the shareholder or their financial intermediary to determine that the shareholder is eligible to exercise the Conversion Feature, and the shareholder or their financial intermediary may be required to maintain records that substantiate the holding period of Class C or Class CX shares.

In addition, a financial intermediary may sponsor and/or control programs or platforms that impose a different conversion schedule or eligibility requirements for conversions of Class C or Class CX shares. In these cases, Class C and Class CX shares of certain shareholders may not be eligible for automatic conversion pursuant to the Conversion Feature as described above. The Fund has no responsibility for overseeing, monitoring or implementing a financial intermediary’s process for determining whether a shareholder meets the required holding period for automatic conversion. Please consult with your financial intermediary if you have any questions regarding the Conversion Feature.

Share Class Conversions Not Permitted

The following share class conversions are not permitted:

■

Conversions into Class A from Class A2 of the same Fund.

■

Conversions into Class A2, Class AX, Class CX, Class P, Class RX or Class S of the same Fund.

Rights Reserved by the Funds

Each Fund and its agents reserve the right at any time to:

■

Reject or cancel all or any part of any purchase or exchange order.

■

Modify any terms or conditions related to the purchase, redemption or exchange of shares of any Fund.

■

Reject or cancel any request to establish a Systematic Purchase Plan or Systematic Redemption Plan.

■

Modify or terminate any sales charge waivers or exceptions.

■

Suspend, change or withdraw all or any part of the offering made by this prospectus.

Excessive Short-Term Trading Activity (Market Timing) Disclosures

While the Funds provide their shareholders with daily liquidity, their investment programs are designed to serve long-term investors and are not designed to accommodate excessive short-term trading activity in violation of our policies described below. Excessive short-term trading activity in the Funds’ shares (i.e., a purchase of Fund shares followed shortly thereafter by a redemption of such shares, or vice versa) may hurt the long-term performance of certain Funds by requiring them to maintain an excessive amount of cash or to liquidate portfolio holdings at a disadvantageous time, thus interfering with the efficient management of such Funds by causing them to incur increased brokerage and administrative costs. Where excessive short-term trading activity seeks to take advantage of arbitrage opportunities from stale prices for portfolio securities, the value of Fund shares held by long-term investors may be diluted. The Board has adopted policies and procedures designed to discourage excessive or short-term trading of Fund shares for all Funds except the money market funds,

A-16 The Invesco Funds

Invesco Conservative Income Fund, and Invesco Short Term Municipal Fund. However, there is the risk that these Funds’ policies and procedures will prove ineffective in whole or in part to detect or prevent excessive or short-term trading. These Funds may alter their policies at any time without prior notice to shareholders if the Adviser believes the change would be in the best interests of long-term shareholders.

Invesco and certain of its corporate affiliates (Invesco and such affiliates, collectively, the Invesco Affiliates) currently use the following tools designed to discourage excessive short-term trading in the retail Funds:

■

Trade activity monitoring.

■

Discretion to reject orders.

■

Purchase blocking.

■

The use of fair value pricing consistent with procedures approved by the Board.

Each of these tools is described in more detail below. Although these tools are designed to discourage excessive short-term trading, you should understand that none of these tools alone nor all of them taken together eliminate the possibility that excessive short-term trading activity in the Funds will occur. Moreover, each of these tools involves judgments that are inherently subjective. Invesco Affiliates seek to make these judgments to the best of their abilities in a manner that they believe is consistent with long-term shareholder interests.

Money Market Funds. The Boards of Invesco Government Money Market Fund, Invesco Premier Portfolio, Invesco Premier Tax-Exempt Portfolio, Invesco Premier U.S. Government Money Portfolio and Invesco U.S. Government Money Portfolio (the money market funds) have not adopted any policies and procedures that would limit frequent purchases and redemptions of such Funds’ shares. The Boards of the money market funds considered the risks of not having a specific policy that limits frequent purchases and redemptions, and determined that those risks were minimal. Nonetheless, to the extent that a money market fund must maintain additional cash and/or securities with short-term durations in greater amounts than may otherwise be required or borrow to honor redemption requests, the money market fund’s yield could be negatively impacted.

The Boards of the money market funds do not believe that it is appropriate to adopt any such policies and procedures for the money market funds for the following reasons:

■

The money market funds are offered to investors as cash management vehicles; therefore, investors should be able to purchase and redeem shares regularly and frequently.

■

One of the advantages of a money market fund as compared to other investment options is liquidity. Any policy that diminishes the liquidity of the money market funds will be detrimental to the continuing operations of such Funds.

■

With respect to the money market funds maintaining a constant net asset value, the money market funds’ portfolio securities are valued on the basis of amortized cost, and such Funds seek to maintain a constant net asset value. As a result, the money market funds are not subject to price arbitrage opportunities.

■

With respect to the money market funds maintaining a constant net asset value, because such Funds seek to maintain a constant net asset value, investors are more likely to expect to receive the amount they originally invested in the Funds upon redemption than other mutual funds.

Invesco Conservative Income Fund. The Board of Invesco Conservative Income Fund has not adopted any policies and procedures that would limit frequent purchases and redemptions of such Fund’s shares. The Board of Invesco Conservative Income Fund considered the risks of not having a specific policy that limits frequent purchases and redemptions, and determined that those risks were minimal especially in light of the reasons for not having such a policy as described below. Nonetheless, to the extent that the Fund must maintain additional cash and/or securities with short-term durations in greater amounts than may otherwise be required or borrow to honor redemption requests, the Fund’s yield could be negatively impacted.

The Board of the Invesco Conservative Income Fund does not believe that it is appropriate to adopt any such policies and procedures for the Fund for the following reasons:

■

The Fund is offered to investors as a cash management vehicle; investors perceive an investment in the Fund as an alternative to cash and must be able to purchase and redeem shares regularly and frequently.

■

One of the advantages of the Fund as compared to other investment options is liquidity. Any policy that diminishes the liquidity of the Fund will be detrimental to the continuing operations of the Fund.

Excessive trading activity in the Fund’s shares may cause the Fund to incur increased brokerage and administrative costs.

The Fund and its agent reserve the right at any time to reject or cancel any part of any purchase order. This could occur if the Fund determines that such purchase may disrupt the Fund’s operation or performance.

Invesco Short Term Municipal Fund. The Board of Invesco Short Term Municipal Fund has not adopted any policies and procedures that would limit frequent purchases and redemptions of such Fund’s shares. The Board of Invesco Short Term Municipal Fund considered the risks of not having a specific policy that limits frequent purchases and redemptions, and determined that those risks were minimal, especially in light of the reasons for not having such a policy as described below. Nonetheless, to the extent that the Fund must maintain additional cash and/or securities with short-term durations in greater amounts than may otherwise be required or borrow to honor redemption requests, the Fund’s yield could be negatively impacted.

The Board of Invesco Short Term Municipal Fund does not believe that it is appropriate to adopt any such policies and procedures for the Fund for the following reasons:

■

The Fund is designed to address the needs of retail investors who seek liquidity in their investment and seek the ability to purchase and redeem shares at any time.

■

Any policy that diminishes the ability of shareholders to purchase and redeem shares of the Fund will be detrimental to the continuing operations of the Fund.

■

The Fund generally invests in short duration liquid investment grade municipal securities.

Excessive trading activity in the Fund’s shares may cause the Fund to incur increased brokerage and administrative costs. The Fund and its agent reserve the right at any time to reject or cancel any part of any purchase order. This could occur if the Fund determines that such purchase may disrupt the Fund’s operation or performance.

Trade Activity Monitoring

Invesco Affiliates monitor selected trades on a daily basis in an effort to detect excessive short-term trading activities. If, as a result of this monitoring, Invesco Affiliates believe that a shareholder has engaged in excessive short-term trading, they will seek to act in a manner that they believe is consistent with the best interests of long-term investors, which may include taking steps such as (i) asking the shareholder to take action to stop such activities or (ii) refusing to process future purchases or exchanges related to such activities in the shareholder’s accounts other than exchanges into a money market fund. Invesco Affiliates will use reasonable efforts to apply the Funds’ policies uniformly given the practical limitations described above.

The ability of Invesco Affiliates to monitor trades that are made through accounts that are maintained by intermediaries (rather than the Funds’ transfer agent) and through conduit investment vehicles may be limited or non-existent.

Discretion to Reject Orders

If a Fund or an Invesco Affiliate determines, in its sole discretion, that your short-term trading activity is excessive, the Fund may, in its sole discretion, reject any additional purchase and exchange orders. This discretion may be exercised with respect to purchase or exchange orders placed directly with the Funds’ transfer agent or through a financial intermediary.

A-17 The Invesco Funds

Purchase Blocking Policy

The Funds (except those listed below) have adopted a policy under which any shareholder redeeming shares having a value of $50,000 or more from a Fund on any trading day will be precluded from investing in that Fund for 30 calendar days after the redemption transaction date. The policy applies to redemptions and purchases that are part of exchange transactions. Under the purchase blocking policy, certain purchases will not be prevented and certain redemptions will not trigger a purchase block, such as: purchases and redemptions of shares having a value of less than $50,000; systematic purchase, redemption and exchange account options; transfers of shares within the same Fund; non-discretionary rebalancing in fund-of-funds; asset allocation features; fee-based accounts; account maintenance fees; small balance account fees; plan-level omnibus Retirement and Benefit Plans; death and disability and hardship distributions; loan transactions; transfers of assets; Retirement and Benefit Plan rollovers; IRA conversions and re-characterizations; and mandatory distributions from Retirement and Benefit Plans.

The Funds reserve the right to modify any of the parameters (including those not listed above) of the purchase blocking policy at any time. Further, the purchase blocking policy may be waived with respect to specific shareholder accounts in those instances where the Adviser determines that its surveillance procedures are adequate to detect frequent trading in Fund shares.

If an account is maintained by a financial intermediary whose systems are unable to apply Invesco’s purchase blocking policy, the Adviser will accept the establishment of an account only if the Adviser believes the policies and procedures are reasonably designed to enforce the frequent trading policies of the Funds. You should refer to disclosures provided by the financial intermediary with which you have an account to determine the specific trading restrictions that apply to you. If the Adviser identifies any activity that may constitute frequent trading, it reserves the right to contact the intermediary and request that the intermediary either provide information regarding an account owner’s transactions or restrict the account owner’s trading. There is no guarantee that all instances of frequent trading in Fund shares will be prevented.

The purchase blocking policy does not apply to Invesco Conservative Income Fund, Invesco Short Term Municipal Fund, Invesco Government Money Market Fund, Invesco Premier Portfolio, Invesco Premier Tax-Exempt Portfolio, Invesco Premier U.S. Government Money Portfolio and Invesco U.S. Government Money Portfolio.

Pricing of Shares

Determination of Net Asset Value

The price of each Fund’s shares is the Fund’s net asset value per share. The Funds (except Invesco Government Money Market Fund, Invesco Premier Portfolio, Invesco Premier U.S. Government Money Portfolio and Invesco U.S. Government Money Portfolio) value portfolio securities for which market quotations are readily available at market value. Securities and other assets quoted in foreign currencies are valued in U.S. dollars based on the prevailing exchange rates on that day. The Funds (except Invesco Government Money Market Fund, Invesco Premier Portfolio,Invesco Premier U.S. Government Money Portfolio and Invesco U.S. Government Money Portfolio) value securities and assets for which market quotations are unavailable at their “fair value,” which is described below. Invesco Government Money Market Fund, Invesco Premier Portfolio, Invesco Premier U.S. Government Money Portfolio and Invesco U.S. Government Money Portfolio value portfolio securities on the basis of amortized cost, which approximates market value. This method of valuation is designed to enable a Fund to price its shares at $1.00 per share. The Funds cannot guarantee their net asset value will always remain at $1.00 per share. Invesco Premier Tax-Exempt Portfolio values its portfolio securities for which market quotations are readily available at market value, and calculates its net asset values to four decimals (e.g., $1.0000). Securities and other assets quoted in foreign currencies are valued in U.S. dollars based on the prevailing exchange rates on that day. The Fund values securities and assets for which market quotations are unavailable at their “fair value,” which is described below.

Even when market quotations are available, they may be stale or unreliable because the security is not traded frequently, trading on the security ceased before the close of the trading market or issuer specific events occurred after the security ceased trading or because of the passage of time between the close of the market on which the security trades and the close of the NYSE and when the Fund calculates its net asset value. Issuer specific events may cause the last market quotation to be unreliable. Such events may include a merger or insolvency, events that affect a geographical area or an industry segment, such as political events or natural disasters, or market events, such as a significant movement in the U.S. market. Where the Adviser determines that the closing price of the security is stale or unreliable, the Adviser will value the security at its fair value.

Fair value is that amount that the owner might reasonably expect to receive for the security upon its current sale. A fair value price is an estimated price that requires consideration of all appropriate factors, including indications of fair value available from pricing services. Fair value pricing involves judgment and a Fund that uses fair value methodologies may value securities higher or lower than another Fund using market quotations or its own fair value methodologies to price the same securities. Investors who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive a greater or lesser number of shares, or higher or lower redemption proceeds, than they would have received if the Fund had not fair-valued the security or had used a different methodology.

The Board has delegated the daily determination of fair value prices to the Adviser’s valuation committee, which acts in accordance with Board approved policies. Fair value pricing methods and pricing services can change from time to time as approved by the Board.

The intended effect of applying fair value pricing is to compute an NAV that accurately reflects the value of a Fund’s portfolio at the time that the NAV is calculated. An additional intended effect is to discourage those seeking to take advantage of arbitrage opportunities resulting from “stale” prices and to mitigate the dilutive impact of any such arbitrage. However, the application of fair value pricing cannot eliminate the possibility that arbitrage opportunities will exist.

Specific types of securities are valued as follows:

Senior Secured Floating Rate Loans and Senior Secured Floating Rate Debt Securities. Senior secured floating rate loans and senior secured floating rate debt securities are fair valued using evaluated quotes provided by an independent pricing service. Evaluated quotes provided by the pricing service may reflect appropriate factors such as market quotes, ratings, tranche type, industry, company performance, spread, individual trading characteristics, institution-size trading in similar groups of securities and other market data.

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

Foreign Securities. If market quotations are available and reliable for foreign exchange traded equity securities, the securities will be valued at the market quotations. Because trading hours for certain foreign securities end before the close of the NYSE, closing market quotations may become unreliable. If between the time trading ends on a particular security and the close of the customary trading session on the NYSE events occur that are significant and may make the closing price unreliable, the Fund may fair value the security. If an issuer specific event has occurred that the Adviser determines, in its judgment, is likely to have affected the closing price of a foreign security, it will price the security at fair value. The Adviser also relies on a screening process from a pricing vendor to indicate the degree of certainty, based on historical data, that the closing price in the principal market where a foreign security trades is not the current market value as of the close of the NYSE. For foreign securities where the Adviser believes, at the approved degree of certainty, that the price is not reflective of current market value, the Adviser will use the indication of fair value from the pricing service to determine the fair value of the security. The pricing vendor, pricing methodology or degree of certainty may change from time to time.

A-18 The Invesco Funds

Fund securities primarily traded on foreign markets may trade on days that are not business days of the Fund. Because the net asset value of Fund shares is determined only on business days of the Fund, the value of the portfolio securities of a Fund that invests in foreign securities may change on days when you will not be able to purchase or redeem shares of the Fund.

Fixed Income Securities. Fixed income securities, such as government, corporate, asset-backed and municipal bonds, convertible securities, including high yield or junk bonds, and loans, normally are valued on the basis of prices provided by independent pricing services. Prices provided by the pricing services may be determined without exclusive reliance on quoted prices, and may reflect appropriate factors such as institution-size trading in similar groups of securities, developments related to special securities, dividend rate, maturity and other market data. Pricing services generally value fixed income securities assuming orderly transactions of institutional round lot size, but a Fund may hold or transact in the same securities in smaller, odd lot sizes. Odd lots often trade at lower prices than institutional round lots. Prices received from pricing services are fair value prices. In addition, if the price provided by the pricing service and independent quoted prices are unreliable, the Adviser’s valuation committee will fair value the security using procedures approved by the Board.

Short-term Securities. Invesco Government Money Market Fund, Invesco Premier Portfolio, Invesco Premier U.S. Government Money Portfolio and Invesco U.S. Government Money Portfolio value all their securities at amortized cost. Invesco Limited Term Municipal Income Fund values variable rate securities that have an unconditional demand or put feature exercisable within seven days or less at par, which reflects the market value of such securities.

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

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

Open-end Funds. If a Fund invests in other open-end funds, other than open-end funds that are exchange traded, the investing Fund will calculate its net asset value using the net asset value of the underlying fund in which it invests, and the prospectuses for such open-end funds explain the circumstances under which they will use fair value pricing and the effects of using fair value pricing.

Each Fund, except for Invesco Government Money Market Fund, Invesco Premier Portfolio, Invesco Premier Tax-Exempt Portfolio and Invesco Premier U.S. Government Money Portfolio, generally determines the net asset value of its shares on each day the NYSE is open for trading (a business day) as of approximately 4:00 p.m. Eastern Time (the customary close of regular trading) or earlier in the case of a scheduled early close. In the event of an unscheduled early close of the NYSE, each Fund, except for Invesco Government Money Market Fund, Invesco Premier Portfolio, Invesco Premier Tax-Exempt Portfolio and Invesco Premier U.S. Government Money Portfolio, generally still will determine the net asset value of its shares as of 4:00 p.m. Eastern Time on that business day. Portfolio securities traded on the NYSE would be valued at their closing prices unless the investment adviser determines that a “fair value” adjustment is appropriate due to subsequent events occurring after an early close consistent with procedures approved by the Board. Invesco Government Money Market Fund, Invesco Premier Portfolio and Invesco Premier U.S. Government Money Portfolio will generally determine the net asset value of their shares at 5:30 p.m. Eastern Time on each business day. Invesco Premier Tax-Exempt Portfolio will generally determine the net asset value of its shares at 3:00 p.m. Eastern Time on each business day. A business day for Invesco Government Money Market Fund, Invesco Premier Portfolio, Invesco Premier Tax-Exempt Portfolio and Invesco Premier U.S. Government Money Portfolio is any day that (1) both the Federal Reserve Bank of New York and a Fund’s custodian are open for business and (2) the primary trading markets for the Fund’s portfolio instruments are open and the Fund’s management believes there is

an adequate market to meet purchase and redemption requests. Invesco Government Money Market Fund, Invesco Premier Portfolio, Invesco Premier Tax-Exempt Portfolio and Invesco Premier U.S. Government Money Portfolio are authorized not to open for trading on a day that is otherwise a business day if the Securities Industry and Financial Markets Association (SIFMA) recommends that government securities dealers not open for trading; any such day will not be considered a business day. Invesco Government Money Market Fund, Invesco Premier Portfolio, Invesco Premier Tax-Exempt Portfolio and Invesco Premier U.S. Government Money Portfolio, Invesco U.S. Government Money Portfolio also may close early on a business day if SIFMA recommends that government securities dealers close early. If Invesco Government Money Market Fund, Invesco Premier Portfolio, Invesco Premier Tax-Exempt Portfolio or Invesco Premier U.S. Government Money Portfolio uses its discretion to close early on a business day, the Fund will calculate its net asset value as of the time of such closing Invesco Premier Portfolio and Invesco U.S. Government Money Portfolio are authorized to not open for trading on a day that is otherwise a business day if the NYSE recommends that government securities dealers not open for trading; any such day will not be considered a business day. Invesco Premier Portfolio also may close early on a business day if the NYSE recommends that government securities dealers close early.

For financial reporting purposes and shareholder transactions on the last day of the fiscal quarter, transactions are normally accounted for on a trade date basis. For purposes of executing shareholder transactions in the normal course of business (other than shareholder transactions at a fiscal period-end), each Fund’s portfolio securities transactions are recorded no later than the first business day following the trade date.

The Invesco Advantage International Fund, Invesco Balanced-Risk Allocation Fund, Invesco Balanced-Risk Commodity Strategy Fund, Invesco Fundamental Alternatives Fund, Invesco Global Allocation Fund, Invesco Global Strategic Income Fund, Invesco Global Targeted Returns Fund, Invesco Gold & Special Minerals Fund, Invesco High Yield Bond Factor Fund, Invesco International Bond Fund and Invesco Macro Allocation Strategy Fund may each invest up to 25% of their total assets in shares of their respective subsidiaries (the Subsidiaries). The Subsidiaries offer to redeem all or a portion of their shares at the current net asset value per share every regular business day. The value of shares of the Subsidiaries will fluctuate with the value of the respective Subsidiary’s portfolio investments. The Subsidiaries price their portfolio investments pursuant to the same pricing and valuation methodologies and procedures used by the Funds, which require, among other things, that each of the Subsidiaries’ portfolio investments be marked-to-market (that is, the value on each of the Subsidiaries’ books changes) each business day to reflect changes in the market value of the investment.

Each Fund’s current net asset value per share is made available on the Funds’ website at www.invesco.com/us.

Fair Value Pricing

Securities owned by a Fund (except Invesco Government Money Market Fund, Invesco Premier Portfolio, Invesco Premier U.S. Government Money Portfolio and Invesco U.S. Government Money Portfolio) are to be valued at current market value if market quotations are readily available. All other securities and assets of a Fund for which market quotations are not readily available are to be valued at fair value determined in good faith using procedures approved by the Board. An effect of fair value pricing may be to reduce the ability of frequent traders to take advantage of arbitrage opportunities resulting from potentially “stale” prices of portfolio holdings. However, it cannot eliminate the possibility of frequent trading.

Timing of Orders

Each Fund prices purchase, exchange and redemption orders at the net asset value next calculated by the Fund after the Fund’s transfer agent, authorized agent or designee receives an order in good order for the Fund. Purchase, exchange and redemption orders must be received prior to the close of business on a business day, as defined by the applicable Fund, to receive that day’s net asset value. Any applicable sales charges are applied at the time an order is processed.

A-19 The Invesco Funds

Currently, certain financial intermediaries may serve as agents for the Funds and accept orders on their behalf. Where a financial intermediary serves as agent, the order is priced at the Fund’s net asset value next calculated after it is accepted by the financial intermediary. In such cases, if requested by a Fund, the financial intermediary is responsible for providing information with regard to the time that such order for purchase, redemption or exchange was received. Orders submitted through a financial intermediary that has not received authorization to accept orders on a Fund’s behalf are priced at the Fund’s net asset value next calculated by the Fund after it receives the order from the financial intermediary and accepts it, which may not occur on the day submitted to the financial intermediary.

Additional Information Regarding Deferred Tax Liability (only applicable to the Invesco Steelpath Funds)

In calculating the Fund’s daily NAV, the Fund will, among other things, account for its deferred tax liability and/or asset balances. As a result, any deferred tax liability and/or asset is reflected in the Fund’s daily NAV.

The Fund will accrue a deferred income tax liability balance, at the applicable U.S. federal corporate income tax rate plus an estimated state and local income tax rate for its future tax liability associated with MLP distributions considered to be a return of capital, as well as for its future tax liability associated with the capital appreciation of its investments. The Fund’s current and deferred tax liability, if any, will depend upon the Fund’s net investment gains and losses and realized and unrealized gains and losses on investments and therefore may vary greatly from year to year depending on the nature of the Fund’s investments, the performance of those investments and general market conditions. Any deferred tax liability balance will reduce the Fund’s NAV. Upon the Fund’s sale of an MLP security, the Fund may be liable for previously deferred taxes.

The Fund will accrue, in accordance with generally accepted accounting principles, a deferred tax asset balance, which reflects an estimate of the Fund’s future tax benefit associated with net operating losses and unrealized losses. Any deferred tax asset balance will increase the Fund’s NAV. To the extent the Fund has a deferred tax asset balance, the Fund will assess, in accordance with generally accepted accounting principles, whether a valuation allowance, which would offset the value of some or all of the Fund’s deferred tax asset balance, is required. Pursuant to Financial Accounting Standards Board Accounting Standards Codification 740 (FASB ASC 740), the Fund will assess a valuation allowance to reduce some or all of the deferred tax asset balance if, based on the weight of all available evidence, both negative and positive, it is more likely than not that some or all of the deferred tax asset will not be realized. The Fund will use judgment in considering the relative impact of negative and positive evidence. The weight given to the potential effect of negative and positive evidence will be commensurate with the extent to which such evidence can be objectively verified. The Fund’s assessment considers, among other matters, the nature, frequency and severity of current and cumulative losses, the duration of statutory carry forward periods and the associated risk that operating loss and capital loss carry forwards may be limited or expire unused, and unrealized gains and losses on investments. Consideration is also given to market cycles, the severity and duration of historical deferred tax assets, the impact of redemptions, and the level of MLP distributions. The Fund will assess whether a valuation allowance is required to offset some or all of any deferred tax asset in connection with the calculation of the Fund’s NAV per share each day; however, to the extent the final valuation allowance differs from the estimates the Fund used in calculating the Fund’s daily NAV, the application of such final valuation allowance could have a material impact on the Fund’s NAV.

The Fund’s deferred tax asset and/or liability balances are estimated using estimates of effective tax rates expected to apply to taxable income in the years such balances are realized. The Fund will rely to some extent on information provided by MLPs in determining the extent to which distributions received from MLPs constitute a return of capital, which may not be provided to the Fund on a timely basis, to estimate the Fund’s deferred tax liability and/or asset balances for purposes of financial statement reporting and determining its NAV. If such information is not

received from such MLPs on a timely basis, the Fund will estimate the extent to which distributions received from MLPs constitute a return of capital based on average historical tax characterization of distributions made by MLPs. The Fund’s estimates regarding its deferred tax liability and/or asset balances are made in good faith; however, the daily estimate of the Fund’s deferred tax liability and/or asset balances used to calculate the Fund’s NAV could vary dramatically from the Fund’s actual tax liability. Actual income tax expense, if any, will be incurred over many years, depending on if and when investment gains and losses are realized, the then-current basis of the Fund’s assets and other factors. As a result, the determination of the Fund’s actual tax liability may have a material impact on the Fund’s NAV. The Fund’s daily NAV calculation will be based on then current estimates and assumptions regarding the Fund’s deferred tax liability and/or asset balances and any applicable valuation allowance, based on all information available to the Fund at such time. From time to time, the Fund may modify its estimates or assumptions regarding its deferred tax liability and/or asset balances and any applicable valuation allowance as new information becomes available. Modifications of the Fund’s estimates or assumptions regarding its deferred tax liability and/or asset balances and any applicable valuation allowance, changes in generally accepted accounting principles or related guidance or interpretations thereof, limitations imposed on net operating losses (if any) and changes in applicable tax law could result in increases or decreases in the Fund’s NAV per share, which could be material.

Taxes (applicable to all Funds except for the Invesco SteelPath Funds and Invesco Master Loan Fund)

A Fund intends to qualify each year as a regulated investment company (RIC) and, as such, is not subject to entity-level tax on the income and gain it distributes to shareholders. If you are a taxable investor, dividends and distributions you receive from a Fund generally are taxable to you whether you reinvest distributions in additional Fund shares or take them in cash. Every year, you will be sent information showing the amount of dividends and distributions you received from a Fund during the prior calendar year. In addition, investors in taxable accounts should be aware of the following basic tax points as supplemented below where relevant:

Fund Tax Basics

■

A Fund earns income generally in the form of dividends or interest on its investments. This income, less expenses incurred in the operation of a Fund, constitutes the Fund’s net investment income from which dividends may be paid to you. If you are a taxable investor, distributions of net investment income generally are taxable to you as ordinary income.

■

Distributions of net short-term capital gains are taxable to you as ordinary income. A Fund with a high portfolio turnover rate (a measure of how frequently assets within a Fund are bought and sold) is more likely to generate short-term capital gains than a Fund with a low portfolio turnover rate.

■

Distributions of net long-term capital gains are taxable to you as long-term capital gains no matter how long you have owned your Fund shares.

■

A portion of income dividends paid by a Fund to you may be reported as qualified dividend income eligible for taxation by individual shareholders at long-term capital gain rates, provided certain holding period requirements are met. These reduced rates generally are available for dividends derived from a Fund’s investment in stocks of domestic corporations and qualified foreign corporations. In the case of a Fund that invests primarily in debt securities, either none or only a nominal portion of the dividends paid by the Fund will be eligible for taxation at these reduced rates.

■

The use of derivatives by a Fund may cause the Fund to realize higher amounts of ordinary income or short-term capital gain, distributions from which are taxable to individual shareholders at ordinary income tax rates rather than at the more favorable tax rates for long-term capital gain.

■

Distributions declared to shareholders with a record date in December—if paid to you by the end of January—are taxable for federal income tax purposes as if received in December.

■

Any long-term or short-term capital gains realized on the sale or redemption of your Fund shares will be subject to federal income tax. For

A-20 The Invesco Funds

tax purposes an exchange of your shares for shares of another Fund is the same as a sale. An exchange occurs when the purchase of shares of a Fund is made using the proceeds from a redemption of shares of another Fund and is effectuated on the same day as the redemption. Your gain or loss is calculated by subtracting from the gross proceeds your cost basis. Gross proceeds and, for shares acquired on or after January 1, 2012 and disposed of after that date, cost basis will be reported to you and the Internal Revenue Service (IRS). Cost basis will be calculated using the Fund’s default method of average cost, unless you instruct the Fund to use a different calculation method. As a service to you, the Fund will continue to provide to you (but not the IRS) cost basis information for shares acquired before 2012, when available, using the average cost method. Shareholders should carefully review the cost basis information provided by a Fund and make any additional basis, holding period or other adjustments that are required when reporting these amounts on their federal income tax returns. If you hold your Fund shares through a broker (or other nominee), please contact that broker (nominee) with respect to reporting of cost basis and available elections for your account. For more information about the cost basis methods offered by Invesco, please refer to the Tax Center located under the Account Access menu of our website at www.Invesco.com/us.

■

The conversion of shares of one class of a Fund into shares of another class of the same Fund is not taxable for federal income tax purposes and no gain or loss will be reported on the transaction. This is true whether the conversion occurs automatically pursuant to the terms of the class or is initiated by the shareholder.

■

At the time you purchase your Fund shares, the Fund’s net asset value may reflect undistributed income or undistributed capital gains. A subsequent distribution to you of such amounts, although constituting a return of your investment, would be taxable. Buying shares in a Fund just before it declares an income dividend or capital gains distribution is sometimes known as “buying a dividend.” In addition, a Fund’s net asset value may, at any time, reflect net unrealized appreciation, which may result in future taxable distributions to you.

■

By law, if you do not provide a Fund with your proper taxpayer identification number and certain required certifications, you may be subject to backup withholding on any distributions of income, capital gains, or proceeds from the sale of your shares. A Fund also must withhold if the IRS instructs it to do so. When withholding is required, the amount will be 24% of any distributions or proceeds paid.

■

An additional 3.8% Medicare tax is imposed on certain net investment income (including ordinary dividends and capital gain distributions received from a Fund and net gains from redemptions or other taxable dispositions of Fund shares) of U.S. individuals, estates and trusts to the extent that such person’s “modified adjusted gross income” (in the case of an individual) or “adjusted gross income” (in the case of an estate or trust) exceeds a threshold amount. This Medicare tax, if applicable, is reported by you on, and paid with, your federal income tax return.

■

You will not be required to include the portion of dividends paid by a Fund derived from interest on U.S. government obligations in your gross income for purposes of personal and, in some cases, corporate income taxes in many state and local tax jurisdictions. The percentage of dividends that constitutes dividends derived from interest on federal obligations will be determined annually. This percentage may differ from the actual percentage of interest received by the Fund on federal obligations for the particular days on which you hold shares.

■

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

■

If a Fund qualifies to pass through to you the tax benefits from foreign taxes it pays on its investments, and elects to do so, then any foreign taxes it pays on these investments may be passed through to you. You will then be required to include your pro-rata share of these taxes in gross income, even though not actually received by you, and will be entitled either to deduct your share of these taxes in computing your taxable income, or to claim a foreign tax credit for these taxes against your U.S. federal income tax.

■

Foreign investors should be aware that U.S. withholding, special certification requirements to avoid U.S. backup withholding and claim any treaty benefits, and estate taxes may apply to an investment in a Fund.

■

Under the Foreign Account Tax Compliance Act (FATCA), a Fund will be required to withhold a 30% tax on income dividends made by the Fund to certain foreign entities, referred to as foreign financial institutions or non-financial foreign entities, that fail to comply (or be deemed compliant) with extensive reporting and withholding requirements designed to inform the U.S. Department of the Treasury of U.S.-owned foreign investment accounts. After December 31, 2018, FATCA withholding also would have applied to certain capital gain distributions, return of capital distributions and the proceeds arising from the sale of Fund shares; however, based on proposed regulations issued by the IRS, which can be relied upon currently, such withholding is no longer required unless final regulations provide otherwise (which is not expected). A Fund may disclose the information that it receives from its shareholders to the IRS, non-U.S. taxing authorities or other parties as necessary to comply with FATCA or similar laws. Withholding also may be required if a foreign entity that is a shareholder of a Fund fails to provide the Fund with appropriate certifications or other documentation concerning its status under FATCA.

■

If a Fund invests in an underlying fund taxed as a RIC, please see any relevant section below for more information regarding the Fund’s investment in such underlying fund.

The above discussion concerning the taxability of Fund dividends and distributions and of redemptions and exchanges of Fund shares is inapplicable to investors holding shares through a tax-advantaged arrangement, such as Retirement and Benefit Plans or 529 college savings plans. Such investors should refer to the applicable account documents/program description for that arrangement for more information regarding the tax consequences of holding and redeeming Fund shares.

Funds Investing in Municipal Securities

■

You will not be required to include the “exempt-interest” portion of dividends paid by the Fund in either your gross income for federal income tax purposes or your net investment income subject to the additional 3.8% Medicare tax. You will be required to report the receipt of exempt-interest dividends and other tax-exempt interest on your federal income tax returns. The percentage of dividends that constitutes exempt-interest dividends will be determined annually. This percentage may differ from the actual percentage of exempt interest received by the Fund for the particular days in which you hold shares.

■

A Fund may invest in municipal securities the interest on which constitutes an item of tax preference and could give rise to a federal alternative minimum tax liability for noncorporate shareholders, unless such municipal securities were issued in 2009 or 2010.

■

Exempt-interest dividends from interest earned on municipal securities of a state, or its political subdivisions, generally are exempt from that state’s personal income tax. Most states, however, do not grant tax-free treatment to interest from municipal securities of other states.

■

A Fund may invest a portion of its assets in securities that pay income that is not tax-exempt. To the extent that dividends paid by a Fund are derived from taxable investments or realized capital gains, they will be taxable as ordinary income or long-term capital gains.

■

A Fund may distribute to you any market discount and net short-term capital gains from the sale of its portfolio securities. If you are a taxable investor, Fund distributions from this income are taxable to you as ordinary income, and generally will neither qualify for the dividends-received deduction in the case of corporate shareholders nor as qualified dividend income subject to reduced rates of taxation in the case of noncorporate shareholders.

■

Exempt-interest dividends from a Fund are taken into account when determining the taxable portion of your social security or railroad retirement benefits, may be subject to state and local income taxes, may affect the deductibility of interest on certain indebtedness, and may have other collateral federal income tax consequences for you.

■

There are risks that: (a) a security issued as tax-exempt may be reclassified by the IRS or a state tax authority as taxable and/or (b) future

A-21 The Invesco Funds

legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability. In addition, such reclassifications or actions could cause the value of a security, and therefore, the value of the Fund’s shares, to decline.

Money Market Funds

■

A Fund does not anticipate realizing any long-term capital gains.

■

If a Fund, other than Invesco Premier Tax-Exempt Portfolio, expects to maintain a stable net asset value of $1.00 per share, investors should not have any gain or loss on sale or exchange of Fund shares (unless the investor incurs a liquidity fee on such sale or exchange). See “Liquidity Fees and Redemption Gates.”

■

Invesco Premier Tax-Exempt Portfolio rounds its current net asset value per share to a minimum of the fourth decimal place, therefore, investors will have gain or loss on sale or exchange of shares of the Fund calculated by subtracting your cost basis from the gross proceeds received from the sale or exchange.

■

There is some degree of uncertainty with respect to the tax treatment of liquidity fees received by a Fund, and such tax treatment may be the subject of future IRS guidance. If a Fund receives liquidity fees, it will consider the appropriate tax treatment of such fees to the Fund at such time.

■

Because the Invesco Premier Tax-Exempt Portfolio is not expected to maintain a stable share price, a sale or exchange of Fund shares may result in a capital gain or loss for you. Unless you choose to adopt a simplified “NAV method” of accounting (described below), any capital gain or loss on the sale or exchange of Fund shares (as noted above) generally will be treated either as short-term if you held your Fund shares for one year or less, or long-term if you held your Fund shares longer. If you elect to adopt the NAV method of accounting, rather than computing gain or loss on every taxable disposition of Fund shares as described above, you would determine your gain or loss based on the change in the aggregate value of your Fund shares during a computation period (such as your taxable year), reduced by your net investment (purchases minus sales) in those shares during that period. Under the NAV method, any resulting net capital gain or loss would be treated as short-term capital gain or loss.

Funds Investing in Real Estate Securities

■

Because of “noncash” expenses such as property depreciation, the cash flow of a REIT that owns properties will exceed its taxable income. The REIT, and in turn a Fund, may distribute this excess cash to shareholders. Such a distribution is classified as a return of capital. Return of capital distributions generally are not taxable to you. Your cost basis in your Fund shares will be decreased by the amount of any return of capital. Any return of capital distributions in excess of your cost basis will be treated as capital gains.

■

Dividends paid to shareholders from the Funds’ investments in U.S. REITs generally will not qualify for taxation at long-term capital gain rates applicable to qualified dividend income.

■

The Fund may derive “excess inclusion income” from certain equity interests in mortgage pooling vehicles either directly or through an investment in a U.S. REIT. Please see the SAI for a discussion of the risks and special tax consequences to shareholders in the event the Fund realizes excess inclusion income in excess of certain threshold amounts.

■

Under the Tax Cuts and Jobs Act, “qualified REIT dividends” (i.e., ordinary REIT dividends other than capital gain dividends and portions of REIT dividends designated as qualified dividend income) are treated as eligible for a 20% deduction by noncorporate taxpayers. The Fund may choose to report the special character of “qualified REIT dividends” to a shareholder, provided both the Fund and a shareholder meet certain holding period requirements with respect to their shares.

■

The Fund’s foreign shareholders should see the SAI for a discussion of the risks and special tax consequences to them from a sale of a U.S. real property interest by a REIT in which the Fund invests.

Funds Investing in Partnerships

■

Taxes,penalties, and interest associated with an audit of a partnership are generally required to be assessed and collected at the partnership level. Therefore, an adverse federal income tax audit of a partnership that a Fund invests in (including MLPs taxed as partnerships) could result in the Fund being required to pay federal income tax. A Fund may have little input in any audit asserted against a partnership and may be contractually or legally obligated to make payments in regard to deficiencies asserted without the ability to put forward an independent defense. Accordingly, even if a partnership in which the Fund invests were to remain classified as a partnership (instead of as a corporation), it could be required to pay additional taxes, interest and penalties as a result of an audit adjustment, and the Fund, as a direct or indirect partner of such partnership, could be required to bear the economic burden of those taxes, interest and penalties, which would reduce the value of Fund shares.

■

Under the Tax Cuts and Jobs Act “qualified publicly traded partnership income” is treated as eligible for a 20% deduction by noncorporate taxpayers. The legislation does not contain a provision permitting a RIC, such as a Fund, to pass the special character of this income through to its shareholders. It is uncertain whether a future technical corrections bill or regulations issued by the IRS will address this issue to enable a Fund to pass through the special character of “qualified publicly traded partnership income” to its shareholders.

■

Some amounts received by a Fund from the MLPs in which it invests likely will be treated as returns of capital to such Fund because of accelerated deductions available to the MLPs. The receipt of returns of capital from the MLPs in which a Fund invests could cause some or all of the Fund’s distributions to be classified as a return of capital. Return of capital distributions generally are not taxable to you. Your cost basis in your Fund shares will be decreased by the amount of any return of capital. Any return of capital distributions in excess of your cost basis will be treated as capital gains.

Funds Investing in Commodities

■

The Funds’ strategies of investing through their respective Subsidiary in derivatives and other financially linked instruments whose performance is expected to correspond to the commodity markets may cause the Funds to recognize more ordinary income and short-term capital gains taxable as ordinary income than would be the case if the Funds invested directly in commodities.

■

The Funds must meet certain requirements under the Code for favorable tax treatment as a RIC, including asset diversification and income requirements. The Funds intend to treat the income each derives from commodity-linked notes as qualifying income based on an opinion from counsel confirming that income from such investments should be qualifying income because such commodity-linked notes constitute securities under section 2(a)(36) of the 1940 Act. Each Subsidiary will be classified for federal income tax purposes as a controlled foreign corporation (CFC) with respect to the Fund. As such, the Fund will be required to include in its gross income each year amounts earned by the Subsidiary during that year (“Subpart F” income), whether or not such earnings are distributed by the Subsidiary to the Fund (deemed inclusions). Recently released Treasury Regulations also permit the Fund to treat such deemed inclusions of “Subpart F” income from the Subsidiary as qualifying income to the Fund, even if the Subsidiary does not make a distribution of such income. Consequently, the Fund and the Subsidiary reserve the right to rely on deemed inclusions being treated as qualifying income to the Fund consistent with recently released Treasury Regulations. If, contrary to the opinion of counsel or other guidance issued by the IRS, the IRS were to determine that income from direct investment in commodity-linked notes is non-qualifying, a Fund might fail to satisfy the income requirement. In lieu of disqualification, the Funds are permitted to pay a tax for certain failures to satisfy the asset diversification or income requirements, which, in general, are limited to those due to reasonable cause and not willful neglect. The Funds intend

A-22 The Invesco Funds

to limit their investments in their respective Subsidiary to no more than 25% of the value of each Fund’s total assets in order to satisfy the asset diversification requirement.

■

The Invesco Balanced-Risk Commodity Strategy Fund received a PLR from the IRS holding that income from a form of commodity-linked note is qualifying income. However, the IRS has revoked the ruling on a prospective basis, thus allowing the Fund to continue to rely on its private letter ruling to treat income from commodity-linked notes purchased on or before June 30, 2017 as qualifying income. After that time the Invesco Balanced-Risk Commodity Strategy Fund expects to rely on the opinion of counsel described above.

Funds Investing in Foreign Currencies

■

The Funds may realize gains from the sale or other disposition of foreign currencies (including but not limited to gains from options, futures or forward contracts) derived from investing in securities or foreign currencies. The U.S. Treasury Department is authorized to issue regulations on whether the realization of such foreign currency gains is qualified income for the Funds. If such regulations are issued, each Fund may not qualify as a RIC and/or the Fund may change its investment policy. As of the date of this prospectus, no regulations have been issued pursuant to this authorization. It is possible, however, that such regulations may be issued in the future. Additionally, the IRS has not issued any guidance on how to apply the asset diversification test to such foreign currency positions. Thus, the IRS’ determination as to how to treat such foreign currency positions for purposes of satisfying the asset diversification test might differ from that of each Fund resulting in the Fund’s failure to qualify as a RIC. In lieu of disqualification, each Fund is permitted to pay a tax for certain failures to satisfy the asset diversification or income requirements, which, in general, are limited to those due to reasonable cause and not willful neglect.

■

The Funds’ transactions in foreign currencies may give rise to ordinary income or loss to the extent such income or loss results from fluctuations in the value of the foreign currency concerned. This treatment could increase or decrease the Funds' ordinary income distributions to you, and may cause some or all of the Funds' previously distributed income to be classified as a return of capital. Return of capital distributions generally are not taxable to you. Your cost basis in your Fund shares will be decreased by the amount of any return of capital. Any return of capital distributions in excess of your cost basis will be treated as capital gains.

This discussion of “Taxes” is for general information only and not tax advice. All investors should consult their own tax advisers as to the federal, state, local and foreign tax provisions applicable to them.

Taxes (applicable to the Invesco SteelPath Funds)

Although the Code generally provides that a RIC does not pay an entity-level income tax, provided that it distributes all or substantially all of its income, the Fund is not and does not anticipate becoming eligible to elect to be treated as a RIC because most or substantially all of the Fund’s investments will consist of investments in MLP securities. The RIC tax rules therefore have no application to the Fund or to its shareholders. As a result, the Fund is treated as a regular corporation, or “C” corporation, for U.S. federal income tax purposes, and generally is subject to U.S. federal income tax on its taxable income at the corporate income tax rate. In addition, as a regular corporation, the Fund will be subject to state and local taxes by reason of its tax status and its investments in MLPs. Therefore, the Fund may have to pay federal, multiple state, and local taxes, which would reduce the Fund’s cash available to make distributions to shareholders. An estimate for federal, state, and local tax liabilities will reduce the fund’s net asset value. The extent to which the Fund is required to pay U.S. federal, state or local corporate income, franchise or other corporate taxes could materially reduce the Fund’s cash available to make distributions to shareholders. In addition, investors in taxable accounts should be aware of the following basic tax points as supplemented below where relevant:

Fund Tax Basics

■

The Fund intends to invest a significant portion of its assets in MLPs, which are generally treated as partnerships for U.S. federal income tax purposes. To the extent that the Fund invests in equity securities of an MLP, the Fund will be a partner in such MLP. Accordingly, the Fund will be required to take into account the Fund’s allocable share of the income, gains, losses, deductions, and credits recognized by each such MLP, regardless of whether the MLP distributes cash to the Fund. MLP distributions to partners, such as the Fund, are not taxable unless the cash amount (or in certain cases, the fair market value of marketable securities) distributed exceeds the Fund’s basis in its MLP interest. The Fund expects that the cash distributions it will receive with respect to its investments in equity securities of MLPs will exceed the net taxable income allocated to the Fund from such MLPs because of tax deductions such as depreciation, amortization and depletion that will be allocated to the Fund from the MLPs. No assurance, however, can be given in this regard. If this expectation is not realized, the Fund will have a larger corporate income tax expense than expected, which will result in less cash available for distribution to shareholders.

■

The Fund will recognize gain or loss on the sale, exchange or other taxable disposition of its portfolio assets, including equity securities of MLPs, equal to the difference between the amount realized by the Fund on the sale, exchange or other taxable disposition and the Fund’s adjusted tax basis in such assets. Any such gain will be subject to U.S. federal income tax at the corporate income tax rate, regardless of how long the Fund has held such assets since preferential capital gain rates do not apply to regular corporations such as the Fund. The amount realized by the Fund in any case generally will be the amount paid by the purchaser of the assets plus, in the case of MLP equity securities, the Fund’s allocable share, if any, of the MLP’s debt that will be allocated to the purchaser as a result of the sale, exchange or other taxable disposition. The Fund’s tax basis in its equity securities in an MLP generally is equal to the amount the Fund paid for the equity securities, (i) increased by the Fund’s allocable share of the MLP’s net taxable income and certain MLP debt, if any, and (ii) decreased by the Fund’s allocable share of the MLP’s net losses and any distributions received by the Fund from the MLP. Although any distribution by an MLP to the Fund in excess of the Fund’s allocable share of such MLP’s net taxable income may create a temporary economic benefit to the Fund, net of a deferred tax liability, such distribution will decrease the Fund’s tax basis in its MLP investment and will therefore increase the amount of gain (or decrease the amount of loss) that will be recognized on the sale of an equity security in the MLP by the Fund. To the extent that the Fund has a net capital loss in any year, the net capital loss can be carried back three taxable years and forward five taxable years to reduce the Fund’s capital gains in such years. In the event a capital loss carryover cannot be utilized in the carryover periods, the Fund’s federal income tax liability may be higher than expected, which will result in less cash available to distribute to shareholders.

■

Distributions by the Fund of cash or property in respect of the shares (other than certain distributions in redemption of shares) will be treated as dividends for U.S. federal income tax purposes to the extent paid from the Fund’s current or accumulated earnings and profits (as determined under U.S. federal income tax principles). Generally, the Fund’s earnings and profits are computed based upon the Fund’s taxable income (loss), with certain specified adjustments. Any such dividend likely will be eligible for the dividends-received deduction if received by an otherwise qualifying corporate U.S. shareholder that meets certain holding period and other requirements for the dividends-received deduction. Dividends paid by the Fund to certain non-corporate U.S. shareholders (including individuals), generally are eligible for U.S. federal income taxation at the rates generally applicable to long-term capital gains for individuals provided that the U.S. shareholder receiving the dividend satisfies applicable holding period and other requirements. Otherwise, dividends paid by the Fund to non-corporate U.S. Shareholders (including individuals) will be taxable at ordinary income rates.

■

If the amount of a Fund distribution exceeds the Fund’s current and accumulated earnings and profits, such excess will be treated first as a

A-23 The Invesco Funds

tax- deferred return of capital to the extent of, and in reduction of, a shareholder’s tax basis in the shares, and thereafter as capital gain to the extent the shareholder held the shares as a capital asset. Any such capital gain will be long-term capital gain if such shareholder has held the applicable shares for more than one year. The portion of the distribution received by a shareholder from the Fund that is treated as a return of capital will decrease the shareholder’s tax basis in his or her Fund shares (but not below zero), which will result in an increase in the amount of gain (or decrease in the amount of loss) that will be recognized by the shareholder for tax purposes on the later sale of such Fund shares.

■

The Fund anticipates that the cash distributions it will receive with respect to its investments in equity securities of MLPs and which it will distribute to its shareholders will exceed the Fund’s current and accumulated earnings and profits. Accordingly, the Fund expects that only a part of its distributions to shareholders with respect to the shares will be treated as dividends for U.S. federal income tax purposes. No assurance, however, can be given in this regard.

■

Special rules may apply to the calculation of the Fund’s earnings and profits. For example, the Fund’s earnings and profits will be calculated using the straight-line depreciation method rather than the accelerated depreciation method. This difference in treatment may, for example, result in the Fund’s earnings and profits being higher than the Fund’s taxable income or loss in a particular year if the MLPs in which the Fund invests calculate their income using accelerated depreciation. Because of these special earnings profits rules, the Fund may make distributions in a particular year out of earnings and profits (treated as dividends) in excess of the amount of the Fund’s taxable income or loss for such year, which means that a larger percentage of the Fund ’s distributions could be taxable to shareholders as ordinary income instead of tax-deferred return of capital or capital gain.

■

Shareholders that receive distributions in shares rather than in cash will be treated for U.S. federal income tax purposes as having (i) received a cash distribution equal to the fair market value of the shares received and (ii) reinvested such amount in shares.

■

A redemption of shares will be treated as a sale or exchange of such shares, provided the redemption is not essentially equivalent to a dividend, is a substantially disproportionate redemption, is a complete redemption of a shareholder’s entire interest in the Fund, or is in partial liquidation of such Fund. Redemptions that do not qualify for sale or exchange treatment will be treated as distributions as described above. Upon a redemption treated as a sale or exchange under these rules, a shareholder generally will recognize capital gain or loss equal to the difference between the adjusted tax basis of his or her shares and the amount received when they are sold.

■

If the Fund is required to sell portfolio securities to meet redemption requests, the Fund may recognize income and gains for U.S. federal, state and local income and other tax purposes, which may result in the imposition of corporate income or other taxes on the Fund and may increase the Fund’s current and accumulated earnings and profits, which will result in a greater portion of distributions to Fund shareholders being treated as dividends. Any long-term or short-term capital gains realized on sale or redemption of your Fund shares will be subject to federal income tax. For tax purposes an exchange of your shares for shares of another Fund is the same as a sale. An exchange occurs when the purchase of shares of a Fund is made using the proceeds from a redemption of shares of another Fund and is effectuated on the same day as the redemption. Your gain or loss is calculated by subtracting from the gross proceeds your cost basis. Gross proceeds and, for shares acquired on or after January 1, 2012 and disposed of after that date, cost basis will be reported to you and the IRS. Cost basis will be calculated using the Fund’s default method of first-in, first-out (FIFO), unless you instruct the Fund to use a different calculation method. Shareholders should carefully review the cost basis information provided by a Fund and make any additional basis, holding period or other adjustments that are required when reporting these amounts on their federal income tax returns. If you hold your Fund shares through a broker (or other nominee), please contact that broker (nominee) with respect to reporting of cost basis and

available elections for your account. For more information about the cost basis methods offered by Invesco, please refer to the Tax Center located under the Accounts & Services menu of our website at www.invesco.com/us.

■

At the time you purchase your Fund shares, the Fund’s net asset value may reflect undistributed income. A subsequent distribution to you of such amounts, although constituting a return of your investment, would be taxable. Buying shares in a Fund just before it declares an income dividend is sometimes known as “buying a dividend.” In addition, a Fund’s net asset value may, at any time, reflect net unrealized appreciation, which may result in future taxable distributions to you.

■

A 3.8% Medicare tax is imposed on certain net investment income (including ordinary dividends received from a Fund and net gains from redemptions or other taxable dispositions of Fund shares) of U.S. individuals, estates and trusts to the extent that such person’s “modified adjusted gross income” (in the case of an individual) or “adjusted gross income” (in the case of an estate or trust) exceeds a threshold amount. This Medicare tax, if applicable, is reported by you on, and paid with, your federal income tax return.

■

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

■

Taxes, penalties, and interest associated with an audit of a partnership are generally required to be assessed and collected at the partnership level. Therefore, an adverse federal income tax audit of an MLP taxed as a partnership that the Fund invests in could result in the Fund being required to pay federal income tax. The Fund may have little input in any audit asserted against an MLP and may be contractually or legally obligated to make payments in regard to deficiencies asserted without the ability to put forward an independent defense. Accordingly, even if an MLP in which the Fund invests were to remain classified as a partnership, it could be required to pay additional taxes, interest and penalties as a result of an audit adjustment, and the Fund, as a direct or indirect partner of such MLP, could be required to bear the economic burden of those taxes, interest and penalties, which would reduce the value of Fund shares.

A-24 The Invesco Funds

■

Under the Tax Cuts and Jobs Act certain “qualified publicly traded partnership income” (e.g., certain income from certain of the MLPs in which the Fund invests) is treated as eligible for a 20% deduction by noncorporate taxpayers. The Tax Cuts and Jobs Act does not contain a provision permitting an entity, such as the Fund, to benefit from this deduction (since the Fund is taxed as a “C” corporation) or pass the special character of this income through to its shareholders. Qualified publicly traded partnership income allocated to a noncorporate investor investing directly in an MLP might, however, be eligible for the deduction.

Federal Income Taxes (applicable to Invesco Master Loan Fund only)

United States taxes

The Fund is classified as a partnership and will not be a regulated investment company for US federal income tax purposes. As a partnership, the Fund is not a taxable entity for federal income tax purposes and, subject to the application of the partnership audit rules described below, incurs no federal income tax liability. Each Investor is required to take into account its proportionate share of items of income, gain, loss and deduction of the partnership in computing its federal income tax liability regardless of whether or not cash or property distributions are then made by the Fund. Following the close of the Fund’s taxable year end, Investors will receive a tax statement entitled Schedule K-1 Partner’s Share of Income, Deductions, Credits, etc., which reports the tax status of their distributive share of the Fund’s items for the previous year.

Taxation of distributions, sales and exchanges

In general, distributions of money by the Fund to an Investor will represent a non-taxable return of capital up to the amount of an Investor’s adjusted tax basis in its shares. An Investor will recognize gain to the extent that any money distributed by the Fund exceeds the Investor’s adjusted tax basis in its shares. In the case of a non-taxable return of capital by the Fund to an Investor, other than in liquidation of the Investor’s interest in the Fund, the tax basis of his shares will be reduced (but not below zero) and will result in an increase in the amount of gain (or decrease in the amount of loss) that will be recognized by the Investor on the later sale of its shares. A distribution in partial or complete redemption of your shares in the Fund is taxable as a sale or exchange only to the extent the amount of money received exceeds the tax basis of your entire interest in the Fund. Any loss may be recognized only if you redeem your entire interest in the Fund for money.

When you sell shares of the Fund, you may have a capital gain or loss.

Derivatives

The use of derivatives by the Fund may cause the Fund to realize higher amounts of ordinary income or short-term capital gain, allocations of which are taxable to individual Investors at ordinary income tax rates rather than at the more favorable tax rates for long-term capital gain. 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 the Fund from using certain types of derivative instruments as part of its investment strategy.

Risk of audit of the Fund

Under the partnership audit rules, which are generally applicable to tax years beginning after December 31, 2017, the Internal Revenue Service (“IRS”) may collect any taxes resulting from audit adjustments to the Fund’s income tax returns (including any applicable penalties and interest) directly from the Fund. In that case, current Investors would bear some or all of the tax liability resulting from such audit adjustment, even if they did not own interests in the Fund during the tax year under audit. The Fund may have the ability to shift any such tax liability to the Investors in accordance with their interests in the Fund during the year under audit, but there can be no assurance that the Fund will be able to do so under all circumstances. For taxable years not subject to the new audit rules, items of Fund income, gain, loss, deduction and credit will be determined at the Fund level in a unified audit. NO REPRESENTATION OR WARRANTY OF ANY KIND IS MADE WITH RESPECT TO THE TAXATION, DEDUCTIBILITY OR CAPITALIZATION OF ANY ITEM BY THE FUND OR INVESTOR. In addition, the “partnership representative” (tax matters partner, for taxable years before the partnership audit rules become effective) will have the sole authority to act on the Fund’s behalf for purposes of, among other things, federal income tax audits and judicial review of administrative adjustments by the IRS, and any such actions will be binding on the Fund and all of the Investors.

Unrelated business taxable income

An allocable share of a tax-exempt Investor’s income will be “unrelated business taxable income” (“UBTI”) to the extent that the Fund borrows money to acquire property or invests in assets that produce UBTI.

Medicare tax

An additional 3.8% Medicare tax is imposed on certain net investment income of US individuals, estates and trusts to the extent that such person’s “modified adjusted gross income” (in the case of an individual) or “adjusted gross income” (in the case of an estate or trust) exceeds a threshold amount. “Net investment income,” for these purposes, means investment income (including (i) net gains from the taxable disposition of shares of a Fund to the extent the net gain would be taken into account by the Investor if the Fund sold all of its property for fair market value immediately before the disposition of the shares of the Fund, and (ii) an allocable share of a Fund’s interest, dividends and net gains) reduced by the deductions properly allocable to such income. This Medicare tax, if applicable, is reported by Investors on, and paid with, the Investor’s federal income tax return.

State, local and non-US tax matters

An Investor’s distributive share of the Fund’s income, and gains from the sale or exchange of an Investor’s Fund shares, generally are subject to state and local taxes in the jurisdiction in which the Investor resides or is otherwise subject to tax.

Prospective investors should consider their individual state and local tax consequences of an investment in the Fund.

Tax considerations for non-US investors

If, as anticipated, the Fund is not deemed to be engaged in a US trade or business, the Fund generally will be required to withhold tax on the distributive share of certain items of gross income from US sources allocated to non-US Investors at a 30% (or lower treaty) rate. Certain categories of income, including portfolio interest, are not subject to US withholding tax. Capital gains (other than gain realized on disposition of US real property interests) are not subject to US withholding tax unless the non-US Investor is a nonresident alien individual present in the United States for a period or periods aggregating 183 days or more during the taxable year. If, on the other hand, the Fund derives income which is effectively connected with a US trade or business carried on by the Fund, this 30% tax will not apply to such effectively connected income of the Fund, and the Fund generally will be required to withhold tax from the amount of effectively connected income allocable to non-US Investors at the highest rate of tax applicable to US residents, and non-US Investors generally would

A-25 The Invesco Funds

be required to file US income tax returns and be subject to US income tax on a net basis. Gain or loss on a sale of shares will be treated as effectively connected with a U.S. trade or business to the extent that a foreign corporation or foreign individual that owns the shares (whether directly or indirectly through other partnerships) would have had effectively connected gain or loss had the partnership sold its underlying assets and applicable US withholding tax will apply. Non-US Investors may be subject to US estate tax and are subject to special US tax certification requirements.

Other reporting and withholding requirements

Under the Foreign Account Tax Compliance Act (“FATCA”), the Fund will be required to withhold at a 30% rate on certain US source payments (such as interest and dividends) to certain Investors if the Investor fails to provide the Fund with the information which identifies its direct and indirect US ownership. After December 31, 2018, FATCA withholding also would have applied to certain capital gain distributions, return of capital distributions and the proceeds arising from the sale of Fund shares; however, based on proposed regulations issued by the IRS, which can be relied upon currently, such withholding is no longer required unless final regulations provide otherwise (which is not expected). A Fund may disclose the information that it receives from an Investor to the IRS, non-US taxing authorities or other parties as necessary to comply with FATCA or similar laws. Withholding also may be required if a foreign entity that is an Investor fails to provide the Fund with appropriate certifications or other documentation concerning its status under FATCA.

For a more complete discussion of the federal income tax consequences of investing in the Fund, see the Statement of Additional Information.

This discussion of “Federal Income Taxes” is not intended or written to be used as tax advice. Because everyone’s tax situation is unique, Investors should consult their tax professional about federal, state, local and foreign tax consequences before making an investment in the Fund.

Payments to Financial Intermediaries – All Share Classes except Class R6 shares

The financial adviser or intermediary through which you purchase your shares may receive all or a portion of the sales charges and distribution fees discussed above. In addition to those payments, Invesco Distributors and other Invesco Affiliates, may make additional cash payments to financial intermediaries in connection with the promotion and sale of shares of the Funds. These additional cash payments may include cash payments and other payments for certain marketing and support services. Invesco Affiliates make these payments from their own resources, from Invesco Distributors’ retention of initial sales charges and from payments to Invesco Distributors made by the Funds under their 12b-1 plans. In the context of this prospectus, “financial intermediaries” include any broker, dealer, bank (including bank trust departments), registered investment adviser, financial planner, retirement plan administrator, insurance company and any other financial intermediary having a selling, administration or similar agreement with Invesco Affiliates.

The benefits Invesco Affiliates receive when they make these payments include, among other things, placing the Funds on the financial intermediary’s fund sales system, and access (in some cases on a preferential basis over other competitors) to individual members of the financial intermediary’s sales force or to the financial intermediary’s management. These payments are sometimes referred to as “shelf space” payments because the payments compensate the financial intermediary for including the Funds in its fund sales system (on its “sales shelf”). Invesco Affiliates compensate financial intermediaries differently depending typically on the level and/or type of considerations provided by the financial intermediary. The payments Invesco Affiliates make may be calculated based on sales of shares of the Funds (Sales-Based Payments), in which case the total amount of such payments shall not exceed 0.25% (0.10% for Class R5 shares) of the public offering price of all shares sold by the financial intermediary during the particular period. Payments may also be

calculated based on the average daily net assets of the applicable Funds attributable to that particular financial intermediary (Asset-Based Payments), in which case the total amount of such cash payments shall not exceed 0.25% per annum of those assets during a defined period. Sales-Based Payments primarily create incentives to make new sales of shares of the Funds and Asset-Based Payments primarily create incentives to retain previously sold shares of the Funds in investor accounts. Invesco Affiliates may pay a financial intermediary either or both Sales-Based Payments and Asset-Based Payments.

Invesco Affiliates are motivated to make these payments as they promote the sale of Fund shares and the retention of those investments by clients of the financial intermediaries. To the extent financial intermediaries sell more shares of the Funds or retain shares of the Funds in their clients’ accounts, Invesco Affiliates benefit from the incremental management and other fees paid to Invesco Affiliates by the Funds with respect to those assets.

The Funds’ transfer agent may make payments to certain financial intermediaries for certain administrative services, including record keeping and sub-accounting of shareholder accounts pursuant to a sub-transfer agency, omnibus account service or sub-accounting agreement. All fees payable by Invesco Affiliates under this category of services are charged back to the Funds, subject to certain limitations approved by the Board.

You can find further details in the Fund’s SAI about these payments and the services provided by financial intermediaries. In certain cases these payments could be significant to the financial intermediaries. Your financial adviser may charge you additional fees or commissions other than those disclosed in this prospectus. You can ask your financial adviser about any payments it receives from Invesco Affiliates or the Funds, as well as about fees and/or commissions it charges.
