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 or hold all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the fund’s operating expenses remain the same. You may be required to pay brokerage commissions on your purchases and sales of Class F-2, F-3, 529-F-2 or 529-F-3 shares of the fund, which are not reflected in the example. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

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 investment results. During the most recent fiscal year, the fund’s portfolio turnover rate was 65% of the average value of its portfolio.

The Income Fund of America / Prospectus 2

Principal investment strategies Normally the fund invests primarily in income-producing securities. These include equity securities, such as dividend-paying common stocks, and debt securities, such as interest-paying bonds.

Generally at least 60% of the fund’s assets will be invested in common stocks and other equity-type securities. However, the composition of the fund’s investments in equity, debt and cash or money market instruments may vary substantially depending on various factors, including market conditions. The fund may also invest up to 30% of its assets in common stocks and other equity-type securities of issuers domiciled outside the United States, including issuers in emerging markets. In addition, the fund may invest up to 20% of its assets in lower quality, higher yielding nonconvertible debt securities (rated Ba1 and BB+ or below by Nationally Recognized Statistical Rating Organizations designated by the fund’s investment adviser or unrated but determined to be of equivalent quality by the fund’s investment adviser); such securities are sometimes referred to as “junk bonds.” The fund may also invest up to 10% of its assets in debt securities tied economically to countries outside the United States; however, these securities must be denominated in U.S. dollars.

The investment adviser uses a system of multiple portfolio managers in managing the fund’s assets. Under this approach, the portfolio of the fund is divided into segments managed by individual managers.

Principal risks This section describes the principal risks associated with investing in the fund. You may lose money by investing in the fund. The likelihood of loss may be greater if you invest for a shorter period of time.

Market conditions — The prices of, and the income generated by, the common stocks and other securities held by the fund may decline – sometimes rapidly or unpredictably – due to various factors, including events or conditions affecting the general economy or particular industries or companies; overall market changes; local, regional or global political, social or economic instability; governmental, governmental agency or central bank responses to economic conditions; levels of public debt and deficits; changes in inflation rates; and currency exchange rate, interest rate and commodity price fluctuations.

Economies and financial markets throughout the world are highly interconnected. Economic, financial or political events, trading and tariff arrangements, wars, terrorism, cybersecurity events, natural disasters, public health emergencies (such as the spread of infectious disease), bank failures and other circumstances in one country or region, including actions taken by governmental or quasi-governmental authorities in response to any of the foregoing, could have impacts on global economies or markets. As a result, whether or not the fund invests in securities of issuers located in or with significant exposure to the countries affected, the value and liquidity of the fund’s investments may be negatively affected by developments in other countries and regions.

3 The Income Fund of America / Prospectus

Issuer risks — The prices of, and the income generated by, securities held by the fund may decline in response to various factors directly related to the issuers of such securities, including reduced demand for an issuer’s goods or services, poor management performance, major litigation, investigations or other controversies related to the issuer, changes in the issuer’s financial condition or credit rating, changes in government regulations affecting the issuer or its competitive environment and strategic initiatives such as mergers, acquisitions or dispositions and the market response to any such initiatives. An individual security may also be affected by factors relating to the industry or sector of the issuer or the securities markets as a whole, and conversely an industry or sector or the securities markets may be affected by a change in financial condition or other event affecting a single issuer.

Investing in income-oriented stocks — The value of the fund’s securities and income provided by the fund may be reduced by changes in the dividend policies of, and the capital resources available for dividend payments at, the companies in which the fund invests.

Investing in debt instruments — The prices of, and the income generated by, bonds and other debt securities held by the fund may be affected by factors such as the interest rates, maturities and credit quality of these securities.

Rising interest rates will generally cause the prices of bonds and other debt securities to fall. Also, when interest rates rise, issuers of debt securities that may be prepaid at any time, such as mortgage- or other asset-backed securities, are less likely to refinance existing debt securities, causing the average life of such securities to extend. A general change in interest rates may cause investors to sell debt securities on a large scale, which could also adversely affect the price and liquidity of debt securities and could also result in increased redemptions from the fund. Falling interest rates may cause an issuer to redeem, call or refinance a debt security before its stated maturity, which may result in the fund having to reinvest the proceeds in lower yielding securities. Longer maturity debt securities generally have greater sensitivity to changes in interest rates and may be subject to greater price fluctuations than shorter maturity debt securities.

Bonds and other debt securities are also subject to credit risk, which is the possibility that the credit strength of an issuer or guarantor will weaken or be perceived to be weaker, and/or an issuer of a debt security will fail to make timely payments of principal or interest and the security will go into default. Changes in actual or perceived creditworthiness may occur quickly. A downgrade or default affecting any of the fund’s securities could cause the value of the fund’s shares to decrease. Lower quality debt securities generally have higher rates of interest and may be subject to greater price fluctuations than higher quality debt securities. Credit risk is gauged, in part, by the credit ratings of the debt securities in which the fund invests. However, ratings are only the opinions of the rating agencies issuing them and are not guarantees as to credit quality or an evaluation of market risk. The fund’s investment adviser relies on its own credit analysts to research issuers and issues in assessing credit and default risks.

Investing in lower rated debt instruments — Lower rated bonds and other lower rated debt securities, rated Ba1/BB+ or below by Nationally Recognized Statistical Rating Organizations, generally have higher rates of interest and involve greater risk of default or price declines due to changes in the issuer’s creditworthiness than those of higher quality debt securities. The market prices of these securities may fluctuate more than the

The Income Fund of America / Prospectus 4

prices of higher quality debt securities and may decline significantly in periods of general economic difficulty. These risks may be increased with respect to investments in junk bonds.

Investing outside the United States — Securities of issuers domiciled outside the United States or with significant operations or revenues outside the United States, and securities tied economically to countries outside the United States, may lose value because of adverse political, social, economic or market developments (including social instability, regional conflicts, terrorism and war) in the countries or regions in which the issuers are domiciled, operate or generate revenue or to which the securities are tied economically. These securities may also lose value due to changes in foreign currency exchange rates against the U.S. dollar and/or currencies of other countries. Issuers of these securities may be more susceptible to actions of foreign governments, such as nationalization, currency blockage or the imposition of price controls, sanctions, or punitive taxes, each of which could adversely impact the value of these securities. Securities markets in certain countries may be more volatile and/or less liquid than those in the United States. Investments outside the United States may also be subject to different regulatory, legal, accounting, auditing, financial reporting and recordkeeping requirements, and may be more difficult to value, than those in the United States. In addition, the value of investments outside the United States may be reduced by foreign taxes, including foreign withholding taxes on interest and dividends. Further, there may be increased risks of delayed settlement of securities purchased or sold by the fund, which could impact the liquidity of the fund’s portfolio. The risks of investing outside the United States may be heightened in connection with investments in emerging markets.

Management — The investment adviser to the fund actively manages the fund’s investments. Consequently, the fund is subject to the risk that the methods and analyses, including models, tools and data, employed by the investment adviser in this process may be flawed or incorrect and may not produce the desired results. This could cause the fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives.

Your investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency, entity or person. You should consider how this fund fits into your overall investment program.

Investment objectives, strategies and risks The fund’s investment objectives are to provide you with current income while secondarily striving for capital growth. While it has no present intention to do so, the fund’s board may change the fund’s investment objectives without shareholder approval upon 60 days’ prior written notice to shareholders. Normally the fund invests primarily in income-producing securities. These include equity securities, such as dividend-paying common stocks, and debt securities, such as interest-paying bonds.

The fund may also hold cash or cash equivalents, including commercial paper and short-term securities issued by the U.S. government, its agencies and instrumentalities. The percentage of the fund invested in such holdings varies and depends on various factors, including market conditions and purchases and redemptions of fund shares. The investment adviser may determine that it is appropriate to invest a substantial portion of the fund’s assets in such instruments in response to certain circumstances, such as periods of market turmoil. For temporary defensive purposes, the fund may invest without limitation in such instruments. A larger percentage of such holdings could moderate the fund’s investment results in a period of rising market prices. Alternatively, a larger percentage of such holdings could reduce the magnitude of the fund’s loss in a period of falling market prices and provide liquidity to make additional investments or to meet redemptions.

The fund may invest in certain other funds managed by the investment adviser or its affiliates (“Central Funds”) to more effectively invest in a diversified set of securities in a specific asset class such as money market instruments, bonds and other securities. Shares of Central Funds are only offered for purchase to the fund’s investment adviser and its affiliates and other funds, investment vehicles and accounts managed by the fund’s investment adviser and its affiliates. Central Funds do not charge management fees. As a result, the fund does not bear additional management fees when investing in Central Funds, but the fund does bear its proportionate share of Central Fund expenses. The investment results of the portions of the fund’s assets invested in the Central Funds will be based upon the investment results of the Central Funds.

The fund may also lend portfolio securities to brokers, dealers and other institutions that provide cash or U.S. Treasury securities as collateral in an amount at least equal to the value of the securities loaned.

9 The Income Fund of America / Prospectus

The fund relies on the professional judgment of its investment adviser to make decisions about the fund’s portfolio investments. The basic investment philosophy of the investment adviser is to seek to invest in attractively valued companies that, in its opinion, represent good, long-term investment opportunities. The investment adviser believes that an important way to accomplish this is through fundamental analysis, which may include meeting with company executives and employees, suppliers, customers and competitors. Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities.

The investment adviser may consider environmental, social and governance (“ESG”) factors that, depending on the facts and circumstances, are material to the value of an issuer or instrument. ESG factors may include, but are not limited to, environmental issues (e.g., water use, emission levels, waste, environmental remediation), social issues (e.g., human capital, health and safety, changing customer behavior) or governance issues (e.g., board composition, executive compensation, shareholder dilution).

The following are principal risks associated with investing in the fund.

may be more susceptible to actions of foreign governments, such as nationalization, currency blockage or the imposition of price controls, sanctions, or punitive taxes, each of which could adversely impact the value of these securities. Securities markets in certain countries may be more volatile and/or less liquid than those in the United States. Investments outside the United States may also be subject to different regulatory, legal, accounting, auditing, financial reporting and recordkeeping requirements, and may be more difficult to value, than those in the United States. In addition, the value of investments outside the United States may be reduced by foreign taxes, including foreign withholding taxes on interest and dividends. Further, there may be increased risks of delayed settlement of securities purchased or sold by the fund, which could impact the liquidity of the fund’s portfolio. The risks of investing outside the United States may be heightened in connection with investments in emerging markets.

The following are additional risks associated with investing in the fund.

Investing in emerging markets — Investing in emerging markets may involve risks in addition to and greater than those generally associated with investing in the securities markets of developed countries. For instance, emerging market countries tend to have less developed political, economic and legal systems than those in developed countries. Accordingly, the governments of these countries may be less stable and more likely to intervene in the market economy, for example, by imposing capital controls, nationalizing a company or industry, placing restrictions on foreign ownership and on withdrawing sale proceeds of securities from the country, and/or imposing punitive taxes that could adversely affect the prices of securities. Information regarding issuers in emerging markets may be limited, incomplete or inaccurate, and such issuers may not be subject to regulatory, accounting, auditing, and financial reporting and recordkeeping standards comparable to those to which issuers in more developed markets are subject. The fund’s rights with respect to its investments in emerging markets, if any, will generally be governed by local law, which may make it difficult or impossible for the fund to pursue legal remedies or to obtain and enforce judgments in local courts. In addition, the economies of these countries may be dependent on relatively few industries, may have limited access to capital and may be more susceptible to changes in local and global trade conditions and downturns in the world economy. Securities markets in these countries can also be relatively small and have substantially lower trading volumes. As a result, securities issued in these countries may be more volatile and less liquid, more vulnerable to market manipulation, and more difficult to value, than securities issued in countries with more developed economies and/or markets. Less certainty with respect to security valuations may lead to additional challenges and risks in calculating the fund’s net asset value. Additionally, emerging markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by banks, agents and depositories that are less established than those in developed countries.

The Income Fund of America / Prospectus 12

Exposure to country, region, industry or sector — Subject to the fund’s investment limitations, the fund may have significant exposure to a particular country, region, industry or sector. Such exposure may cause the fund to be more impacted by risks relating to and developments affecting the country, region, industry or sector, and thus its net asset value may be more volatile, than a fund without such levels of exposure. For example, if the fund has significant exposure in a particular country, then social, economic, regulatory or other issues that negatively affect that country may have a greater impact on the fund than on a fund that is more geographically diversified.

Interest rate risk — The values and liquidity of the securities held by the fund may be affected by changing interest rates. For example, the values of debt securities may decline when interest rates rise and increase when interest rates fall. Longer maturity debt securities generally have greater sensitivity to changes in interest rates and may be subject to greater price fluctuations than shorter maturity debt securities. The fund may invest in variable and floating rate securities. When the fund holds variable or floating rate securities, a decrease in market interest rates will adversely affect the income received from such securities and the net asset value of the fund’s shares. Although the values of such securities are generally less sensitive to interest rate changes than those of other debt securities, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as market interest rates. Conversely, floating rate securities will not generally increase in value if interest rates decline. During periods of extremely low short-term interest rates, certain of the fund’s debt securities may not be able to maintain a positive yield or total return and, in relatively low interest rate environments, there are heightened risks associated with rising interest rates.

Liquidity risk — Certain fund holdings may be or may become difficult or impossible to sell, particularly during times of market turmoil. Liquidity may be impacted by the lack of an active market for a holding, legal or contractual restrictions on resale, or the reduced number and capacity of market participants to make a market in such holding. Market prices for less liquid or illiquid holdings may be volatile or difficult to determine, and reduced liquidity may have an adverse impact on the market price of such holdings. Additionally, the sale of less liquid or illiquid holdings may involve substantial delays (including delays in settlement) and additional costs and the fund may be unable to sell such holdings when necessary to meet its liquidity needs or to try to limit losses, or may be forced to sell at a loss.

Lending of portfolio securities — Securities lending involves risks, including the risk that the loaned securities may not be returned in a timely manner or at all, which would interfere with the fund’s ability to vote proxies or settle transactions, and/or the risk of a counterparty default. Additionally, the fund may lose money from the reinvestment of collateral received on loaned securities in investments that decline in value, default or do not perform as expected.

Cybersecurity breaches — The fund may be subject to operational and information security risks through breaches in cybersecurity. Cybersecurity breaches can result from deliberate attacks or unintentional events, including “ransomware” attacks, the injection of computer viruses or malicious software code, the use of vulnerabilities in code to gain unauthorized access to digital information systems, networks or devices, or external attacks such as denial-of-service attacks on the investment adviser’s or an affiliate’s website that could render the fund’s network services unavailable to intended end-users. These breaches may, among other things, lead to the unauthorized release of

13 The Income Fund of America / Prospectus

confidential information, misuse of the fund’s assets or sensitive information, the disruption of the fund’s operational capacity, the inability of fund shareholders to transact business, or the destruction of the fund’s physical infrastructure, equipment or operating systems. These events could cause the fund to violate applicable privacy and other laws and could subject the fund to reputational damage, additional costs associated with corrective measures and/or financial loss. The fund may also be subject to additional risks if its third-party service providers, such as the fund’s investment adviser, transfer agent, custodian, administrators and other financial intermediaries, experience similar cybersecurity breaches and potential outcomes. Cybersecurity risks may also impact issuers of securities in which the fund invests, which may cause the fund’s investments in such issuers to lose value.

Large shareholder transactions risk — The fund may experience adverse effects when shareholders, including other funds or accounts advised by the investment adviser, purchase or redeem, individually or in the aggregate, large amounts of shares relative to the size of the fund. For example, when the investment adviser changes allocations in other funds and accounts it manages, such changes may result in shareholder transactions in the fund that are large relative to the size of the fund. Such large shareholder redemptions may cause the fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the fund’s net asset value and liquidity. Similarly, large fund share purchases may adversely affect the fund’s performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. 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. In addition, a large redemption could result in the fund’s current expenses being allocated over a smaller asset base, leading to an increase in the fund’s expense ratio. These risks are heightened when the fund is small.

In addition to the principal investment strategies described above, the fund has other investment practices that are described in the statement of additional information, which includes a description of other risks related to the fund’s principal investment strategies and other investment practices. The fund’s investment results will depend on the ability of the fund’s investment adviser to navigate the risks discussed above as well as those described in the statement of additional information.

Fund comparative indexes The investment results table in this prospectus shows how the fund’s average annual total returns compare with a broad measure of market results and, if applicable, other measures of market results that reflect the fund’s investment universe. The S&P 500 Index is a market capitalization-weighted index based on the results of approximately 500 widely held common stocks. This index is unmanaged, and its results include reinvested dividends and/or distributions but do not reflect the effect of sales charges, commissions, account fees, expenses or U.S. federal income taxes. The 65%/35% S&P 500 Index/Bloomberg U.S. Aggregate Index blends the S&P 500 Index with the Bloomberg U.S. Aggregate Index by weighting their cumulative total returns at 65% and 35%, respectively. This assumes the blend is rebalanced monthly. The Bloomberg U.S. Aggregate Index represents the U.S. investment-grade fixed-rate bond market. This index is unmanaged, and its results include reinvested dividends and/or distributions but do not reflect the effect of sales charges, commissions, account fees, expenses or U.S. federal income taxes.

Fund results All fund results in this prospectus reflect the reinvestment of dividends and capital gain distributions, if any. Unless otherwise noted, fund results reflect any fee waivers and/or expense reimbursements in effect during the periods presented.

Management and organization

Investment adviser Capital Research and Management Company, an experienced investment management organization founded in 1931, serves as the investment adviser to the fund and other funds, including the American Funds. Capital Research and Management Company is a wholly owned subsidiary of The Capital Group Companies, Inc. and is located at 333 South Hope Street, Los Angeles, California 90071. Capital Research and Management Company manages the investment portfolio and business affairs of the fund. The total management fee paid by the fund to its investment adviser for the most recent fiscal year, as a percentage of average net assets, appears in the Annual Fund Operating Expenses table under “Fees and expenses of the fund.” As described more fully in the fund’s statement of additional information, the management fee is based on the daily net assets of the fund and the fund’s monthly gross investment income. A discussion regarding the basis for approval of the fund’s Investment Advisory and Service Agreement by the fund’s board of trustees is contained in the fund’s Form N-CSR for the fiscal period ended January 31, 2025.

Capital Research and Management Company manages equity assets through three equity investment divisions and fixed income assets through its fixed income investment division, Capital Fixed Income Investors. The three equity investment divisions — Capital International Investors, Capital Research Global Investors and Capital World Investors — make investment decisions independently of one another.

The equity investment divisions may, in the future, be incorporated as wholly owned subsidiaries of Capital Research and Management Company. In that event, Capital Research and Management Company would continue to be the investment adviser, and day-to-day investment management of equity assets would continue to be carried out through one or more of these subsidiaries. Although not currently contemplated, Capital Research and Management Company could incorporate its fixed income investment division in the future and engage it to provide day-to-day investment management of fixed income assets. Capital Research and Management Company and each of the funds it advises have received an exemptive order from the U.S. Securities and Exchange Commission that allows Capital Research and Management Company to use, upon approval of the fund’s board, its management subsidiaries and affiliates to provide day-to-day investment management services to the fund, including making changes to the management subsidiaries and affiliates providing such services. The fund’s shareholders have approved this arrangement; however, there is no assurance that Capital Research and Management Company will incorporate its investment divisions or exercise any authority granted to it under the exemptive order.

The Capital System^TM Capital Research and Management Company uses a system of multiple portfolio managers in managing mutual fund assets. Under this approach, the portfolio of a fund is divided into segments managed by individual managers. In addition, Capital Research and Management Company’s investment analysts may make investment decisions with respect to a portion of a fund’s portfolio. Investment decisions are subject to a fund’s objective(s), policies and restrictions and the oversight of the appropriate investment-related committees of Capital Research and Management Company and its investment divisions. The table below shows the investment experience and role in management of the fund for each of the fund’s primary portfolio managers.

Shareholder information

Shareholder services American Funds Service Company, the fund’s transfer agent, offers a wide range of services that you can use to alter your investment program should your needs or circumstances change. These services may be terminated or modified at any time upon 60 days’ prior written notice.

A more detailed description of policies and services is included in the fund’s statement of additional information and the owner’s guide sent to new American Funds shareholders entitled Welcome. Class 529 shareholders should also refer to the applicable program description for information on policies and services relating specifically to their account(s). These documents are available by writing to or calling American Funds Service Company.

Unless otherwise noted or unless the context requires otherwise, references on the following pages to (i) Class A, C, T or F shares also refer to the corresponding Class 529-A, 529-C, 529-T or 529-F shares, (ii) Class F shares refer to Class F-1, F-2 and F-3 shares and (iii) Class R shares refer to Class R-1, R-2, R-2E, R-3, R-4, R-5E, R-5 and R-6 shares.

Purchase, exchange and sale of shares The fund’s transfer agent, on behalf of the fund and Capital Client Group, Inc., the fund’s distributor, is required by law to obtain certain personal information from you or any other person(s) acting on your behalf in order to verify your identity or such other person’s identity. If you do not provide the information, the transfer agent may not be able to open your account. If the transfer agent is unable to verify your identity or that of any other person(s) authorized to act on your behalf, or believes it has identified potentially criminal activity, the fund and Capital Client Group, Inc. reserve the right to close your account or take such other action they deem reasonable or required by law.

When purchasing shares, you should designate the fund or funds in which you wish to invest. Subject to the exception below, if no fund is designated, your money will be held uninvested (without liability to the transfer agent for loss of income or appreciation pending receipt of proper instructions) until investment instructions are received, but for no more than three business days. Your investment will be made at the net asset value (plus any applicable sales charge, in the case of Class A or Class T shares) next determined after investment instructions are received and accepted by the transfer agent. If investment instructions are not received, your money will be invested in Class A shares (or, if you are investing through a financial intermediary who offers only Class T shares, in Class T shares) of American Funds^® U.S. Government Money Market Fund on the third business day after receipt of your investment.

If the amount of your cash investment is $10,000 or less, no fund is designated, and you made a cash investment (excluding exchanges) within the last 16 months, your money will be invested in the same proportion and in the same fund or funds and in the same class of shares in which your last cash investment was made. If you only have one open fund, the money will be invested into such fund on the day received if the investment is otherwise in good order.

Different procedures may apply to certain employer-sponsored arrangements, including, but not limited to, SEP plans, SIMPLE IRA plans and CollegeAmerica accounts.

Valuing shares The net asset value of each share class of the fund is the value of a single share of that class. The net asset value per share is calculated once daily as of the close of regular trading on the New York Stock Exchange, normally 4 p.m. New York time, each day the New York Stock Exchange is open. If the New York Stock Exchange makes a scheduled (e.g., the day after Thanksgiving) or an unscheduled close prior to 4 p.m. New York time, the net asset value of the fund will be determined at approximately the time the New York Stock Exchange closes on that day. If on such a day market quotations and prices from third-party pricing services are not based as of the time of the early close of the New York Stock Exchange but are as of a later time (up to approximately 4 p.m. New York time), for example because the market remains open after the close of the New York Stock Exchange, those later market quotations and prices will be used in determining the fund’s net asset value.

The Income Fund of America / Prospectus 20

Equity securities are valued primarily on the basis of market quotations, and debt securities are valued primarily on the basis of prices from third-party pricing services due to the lack of market quotations. Futures contracts are valued primarily on the basis of settlement prices. The fund’s portfolio investments are valued in accordance with procedures for making fair value determinations if market quotations are not readily available, including procedures to determine the representativeness of third-party vendor prices, or in the event market quotations or third-party vendor prices are not considered reliable. For example, if events occur between the close of markets outside the United States and the close of regular trading on the New York Stock Exchange that, in the opinion of the investment adviser, materially affect the value of any of the fund’s equity securities that trade principally in those international markets, those securities will be valued in accordance with fair value procedures. Similarly, fair value procedures will be employed if an issuer defaults on its debt securities and there is no market for its securities. Use of these procedures is intended to result in more appropriate net asset values and, where applicable, to reduce potential arbitrage opportunities otherwise available to short-term investors.

Because the fund may hold securities that are listed primarily on foreign exchanges that trade on weekends or days when the fund does not price its shares, the values of securities held in the fund may change on days when you will not be able to purchase or redeem fund shares.

Your shares will be purchased at the net asset value (plus any applicable sales charge, in the case of Class A or Class T shares) or sold at the net asset value next determined after American Funds Service Company receives your request, provided that your request contains all information and legal documentation necessary to process the transaction. Orders in good order received after the New York Stock Exchange closes (scheduled or unscheduled) will be processed at the net asset value (plus any applicable sales charge) calculated on the following business day. A contingent deferred sales charge may apply at the time you sell certain Class A and C shares.

Purchase of Class A and C shares You may generally open an account and purchase Class A and C shares by contacting any financial professional (who may impose transaction charges in addition to those described in this prospectus) authorized to sell the fund’s shares. You may purchase additional shares in various ways, including through your financial professional and by mail, telephone, the Internet and bank wire.

Automatic conversion of Class C and Class 529-C shares Class C shares automatically convert to Class A shares in the month of the 8-year anniversary of the purchase date. Class 529-C shares automatically convert to Class 529-A shares, in the month of the 5-year anniversary of the purchase date. The Internal Revenue Service currently takes the position that such automatic conversions are not taxable. Should its position change, the automatic conversion feature may be suspended. If this were to happen, you would have the option of converting your Class C shares to Class A shares or your Class 529-C shares to Class 529-A shares at the anniversary date described above. This exchange would be based on the relative net asset values of the two classes in question, without the imposition of a sales charge or fee, but you might face certain tax consequences as a result.

Purchase of Class F shares You may generally open an account and purchase Class F shares only through fee-based programs of investment dealers that have special

21 The Income Fund of America / Prospectus

agreements with the fund’s distributor, through financial intermediaries that have been approved by, and that have special agreements with, the fund’s distributor to offer Class F shares to self-directed investment brokerage accounts that may charge a transaction fee, through certain registered investment advisors and through other intermediaries approved by the fund’s distributor. These intermediaries typically charge ongoing fees for services they provide. Intermediary fees are not paid by the fund and normally range from .75% to 1.50% of assets annually, depending on the services offered.

Class F-2, F-3, 529-F-2 and 529-F-3 shares may also be available on brokerage platforms of firms that have agreements with the fund’s distributor to offer such shares solely when acting as an agent for the investor. An investor transacting in Class F-2, F-3, 529-F-2 or 529-F-3 shares in these programs may be required to pay a commission and/or other forms of compensation to the broker. Shares of the fund are available in other share classes that have different fees and expenses.

In addition, upon approval by an officer of the fund’s investment adviser, Class F-3 shares (but not Class 529-F-3 shares) are available to institutional investors, which include, but are not limited to, charitable organizations, governmental institutions, corporations and financial intermediaries. For accounts held and serviced by the fund’s transfer agent the minimum investment amount is $1 million.

Purchase of Class 529 shares Class 529 shares may be purchased only through an account established with a 529 college savings plan managed by Capital Research and Management Company. You may open this type of account and purchase Class 529 shares by contacting any financial professional (who may impose transaction charges in addition to those described in this prospectus) authorized to sell such an account. You may purchase additional shares in various ways, including through your financial professional and by mail, telephone, the Internet and bank wire.

Class 529-E shares may be purchased only by employees participating through an eligible employer plan.

Accounts holding Class 529 shares are subject to a $10 account setup fee and an annual $10 account maintenance fee. These fees are waived until further notice.

Investors residing in any state may purchase Class 529 shares through an account established with a 529 college savings plan managed by Capital Research and Management Company. Class 529-A, 529-C, 529-T and 529-F shares are structured similarly to the corresponding Class A, C, T and F shares.

Purchase of Class R shares Class R shares are generally available only to retirement plans established under Internal Revenue Code Sections 401(a), 403(b) or 457, and to nonqualified deferred compensation plans and certain voluntary employee benefit association and post-retirement benefit plans. Class R shares also are generally available only to retirement plans for which plan level or omnibus accounts are held on the books of the fund. Class R-5E, R-5 and R-6 shares are generally available only to fee-based programs or through retirement plan intermediaries. Class R-3 and Class R-5E shares are available through the American Funds SIMPLE IRA Plus Program and other similar programs. In addition, Class R-5 and R-6 shares are available for investment by other registered investment companies and collective investment trusts approved by the fund’s investment adviser or distributor. Except as otherwise provided in this prospectus,

The Income Fund of America / Prospectus 22

Class R shares are generally not available for purchase to retail nonretirement accounts; traditional and Roth individual retirement accounts (IRAs); Coverdell Education Savings Accounts; SEPs, SARSEPs and SIMPLE IRAs held in brokerage accounts; and 529 college savings plans. Class R-6 shares are available to employer-sponsored SEPs, SARSEPs and SIMPLE IRAs held in fee-based programs that are serviced through retirement plan recordkeepers.

Purchases by employer-sponsored retirement plans Eligible retirement plans generally may open an account and purchase Class A or R shares by contacting any investment dealer (who may impose transaction charges in addition to those described in this prospectus) authorized to sell these classes of the fund’s shares. Some or all R share classes may not be available through certain investment dealers. Additional shares may be purchased through a plan’s administrator or recordkeeper.

Class A shares are generally not available for retirement plans using the PlanPremier^® or Recordkeeper Direct^® recordkeeping programs. These programs are proprietary recordkeeping solutions for small retirement plans.

Employer-sponsored retirement plans that are eligible to purchase Class R shares may instead purchase Class A shares and pay the applicable Class A sales charge, provided that their recordkeepers can properly apply a sales charge on plan investments. These plans are not eligible to make initial purchases at the net asset value breakpoint in Class A shares and thereby invest in Class A shares without a sales charge, nor are they eligible to establish a statement of intention that qualifies them to purchase Class A shares without a sales charge. More information about statements of intention can be found under “Sales charge reductions and waivers” in this prospectus. Plans investing in Class A shares with a sales charge may purchase additional Class A shares in accordance with the sales charge table in this prospectus.

Employer-sponsored retirement plans that invested in American Funds Class A shares without any sales charge before April 1, 2004, and that continue to meet the eligibility requirements in effect as of that date for purchasing Class A shares at net asset value, may continue to purchase American Funds Class A shares without any initial or contingent deferred sales charge.

A 403(b) plan may not invest in American Funds Class A or C shares unless it was invested in Class A or C shares before January 1, 2009.

23 The Income Fund of America / Prospectus

Purchase minimums and maximums Purchase minimums described in this prospectus may be waived in certain cases. Minimums are currently waived for purchases of Class F-2 and F-3 shares held under fee-based programs. In addition, the fund reserves the right to redeem the shares of any shareholder for their then current net asset value per share if the shareholder’s aggregate investment in the fund falls below the fund’s minimum initial investment amount. See the statement of additional information for details.

For accounts established with an automatic investment plan, the initial purchase minimum of $250 may be waived if the purchases (including purchases through exchanges from another fund) made under the plan are sufficient to reach $250 within five months of account establishment.

The effective purchase maximums for Class 529-A, 529-C, 529-E, 529-T and 529-F shares will reflect the maximum applicable contribution limits under state law. See the applicable program description for more information.

If you have significant Capital Group Funds holdings, you may not be eligible to invest in Class C or 529-C shares. Specifically, you may not purchase Class C or 529-C shares if you are eligible to purchase Class A or 529-A shares at net asset value. See “Sales charge reductions and waivers” in this prospectus and the statement of additional information for more details regarding sales charge discounts.

The Income Fund of America / Prospectus 24

Exchange Except for Class T shares or as otherwise described in this prospectus, you may exchange your shares for shares of the same class of other Capital Group Funds without a sales charge. Notwithstanding the foregoing, Class A-2 shares of Capital Group KKR Public-Private+ Funds may not be exchanged for shares of the American Funds or Emerging Markets Equities Fund, Inc. Class A, C, T or F shares of any American Fund (other than American Funds U.S. Government Money Market Fund, as described below) may be exchanged for the corresponding 529 share class without a sales charge. Exchanges from Class A, C, T or F shares to the corresponding 529 share class, particularly in the case of Uniform Gifts to Minors Act or Uniform Transfers to Minors Act custodial accounts, may result in significant legal and tax consequences, as described in the applicable program description. Please consult your financial professional before making such an exchange.

Except as indicated above, Class T shares are not eligible for exchange privileges. Accordingly, an exchange of your Class T shares for Class T shares of any other American Funds will normally be subject to any applicable sales charges.

Exchanges of shares from American Funds U.S. Government Money Market Fund initially purchased without a sales charge to shares of other Capital Group Funds will be subject to the appropriate sales charge applicable to the other fund, unless the American Funds U.S. Government Money Market Fund shares were acquired by an exchange from a fund having a sales charge or by reinvestment or cross-reinvestment of dividends or capital gain distributions. For purposes of computing the contingent deferred sales charge on Class C shares, the length of time you have owned your shares will be measured from the first day of the month in which shares were purchased and will not be affected by any permitted exchange.

Exchanges have the same tax consequences as ordinary sales and purchases. For example, to the extent you exchange shares held in a taxable account that are worth more now than what you paid for them, the gain will be subject to taxation.

See “Transactions by telephone, fax or the Internet” in the section “How to sell shares” of this prospectus for information regarding electronic exchanges.

Please see the statement of additional information for details and limitations on moving investments in certain share classes to different share classes and on moving investments held in certain accounts to different accounts.

How to sell shares

You may sell (redeem) shares in any of the following ways:

Employer-sponsored retirement plans

Shares held in eligible retirement plans may be sold through the plan’s administrator or recordkeeper.

Through your dealer or financial advisor (certain charges may apply)

· Shares held for you in your dealer’s name must be sold through the dealer.

· Class F shares must be sold through intermediaries such as dealers or financial advisors.

Writing to American Funds Service Company

· Requests must be signed by the registered shareholder(s).

· A signature guarantee is required if the redemption is:

— more than $250,000;

— made payable to someone other than the registered shareholder(s); or

— sent to an address other than the address of record or to an address of record that has been changed within the previous 10 days.

· American Funds Service Company reserves the right to require signature guarantee(s) on any redemption.

· Additional documentation may be required for redemptions of shares held in corporate, partnership or fiduciary accounts.

Telephoning or faxing American Funds Service Company

· Redemptions by telephone or fax are limited to $250,000 per American Funds shareholder each day.

· Checks must be made payable to the registered shareholder.

· Checks must be mailed to an address of record that has been used with the account for at least 10 days.

Self service using the Internet (capitalgroup.com) or Interactive Voice Response (IVR)

· Redemptions by IVR or the Internet (capitalgroup.com) are limited to $125,000 per American Funds shareholder each day.

· Checks must be made payable to the registered shareholder.

· Checks must be mailed to an address of record that has been used with the account for at least 10 days.

The fund typically expects to remit redemption proceeds one business day following receipt and acceptance of a redemption order, regardless of the method the fund uses to make such payment (e.g., check, wire or automated clearing house transfer). However, payment may take longer than one business day and may take up to seven days as generally permitted by the Investment Company Act of 1940, as amended (the “1940 Act”). Under the 1940 Act, the fund may be permitted to pay redemption proceeds beyond seven days under certain limited circumstances. In addition, if you recently purchased shares and subsequently request a redemption of those shares, the fund will pay the available redemption proceeds once a sufficient period of time has passed to

The Income Fund of America / Prospectus 26

reasonably ensure that checks or drafts, including certified or cashier’s checks, for the shares purchased have cleared (normally seven business days from the purchase date).

Under normal conditions, the fund typically expects to meet shareholder redemptions from a reserve of highly liquid assets, such as cash or cash equivalents. The fund may use additional methods to meet shareholder redemptions, if they become necessary. These methods may include, but are not limited to, the sale of portfolio assets, the use of overdraft protection afforded by the fund’s custodian bank, borrowing from a line of credit or from other funds advised by the investment adviser or its affiliates, and making payment with fund securities or other fund assets rather than in cash (as further discussed in the following paragraph).

Although payment of redemptions normally will be in cash, the fund’s declaration of trust permits payment of the redemption price wholly or partly with portfolio securities or other fund assets under conditions and circumstances determined by the fund’s board of trustees. On the same redemption date, some shareholders may be paid in whole or in part in securities (which may differ among those shareholders), while other shareholders may be paid entirely in cash. In general, in-kind redemptions to affiliated shareholders will as closely as practicable represent the affiliated shareholder’s pro rata share of the fund’s securities, subject to certain exceptions. Securities distributed in-kind to unaffiliated shareholders will be selected by the investment adviser in a manner the investment adviser deems to be fair and reasonable to the fund’s shareholders. The disposal of the securities received in-kind may be subject to brokerage costs and, until sold, such securities remain subject to market risk and liquidity risk, including the risk that such securities are or become difficult to sell. If the fund pays your redemption with illiquid or less liquid securities, you will bear the risk of not being able to sell such securities.

Transactions by telephone, fax or the Internet Generally, you are automatically eligible to redeem or exchange shares by telephone, fax or the Internet, unless you notify us in writing that you do not want any or all of these services. You may reinstate these services at any time.

Unless you decide not to have telephone, fax or Internet services on your account(s), you agree to hold the fund, American Funds Service Company, any of its affiliates or mutual funds managed by such affiliates, and each of their respective directors, trustees, officers, employees and agents harmless from any losses, expenses, costs or liabilities (including attorney fees) that may be incurred in connection with the exercise of these privileges, provided that American Funds Service Company employs reasonable procedures to confirm that the instructions received from any person with appropriate account information are genuine. If reasonable procedures are not employed, American Funds Service Company and/or the fund may be liable for losses due to unauthorized or fraudulent instructions.

Frequent trading of fund shares The fund and Capital Client Group, Inc. reserve the right to reject any purchase order for any reason. The fund is not designed to serve as a vehicle for frequent trading. Frequent trading of fund shares may lead to increased costs to the fund and less efficient management of the fund’s portfolio, potentially resulting in dilution of the value of the shares held by long-term shareholders. Accordingly, purchases, including those that are part of exchange activity, that the fund or Capital Client Group, Inc. has determined could involve actual or potential harm to the fund may be rejected.

The fund, through its transfer agent, American Funds Service Company, maintains surveillance procedures that are designed to detect frequent trading in fund shares. Under these procedures, various analytics are used to evaluate factors that may be indicative of frequent trading. For example, transactions in fund shares that exceed certain monetary thresholds may be scrutinized. American Funds Service Company also may review transactions that occur close in time to other transactions in the same account or in multiple accounts under common ownership or influence. Trading activity that is identified through these procedures or as a result of any other information available to the fund will be evaluated to determine whether such activity might constitute frequent trading. These procedures may be modified from time to time as appropriate to improve the detection of frequent trading, to facilitate monitoring for frequent trading in particular retirement plans or other accounts and to comply with applicable laws.

Under the fund’s frequent trading policy, certain trading activity will not be treated as frequent trading, such as:

· transactions in Class 529 shares;

· purchases and redemptions by investment companies managed or sponsored by the fund’s investment adviser or its affiliates, including reallocations and transactions allowing the investment company to meet its redemptions and purchases;

· retirement plan contributions, loans and distributions (including hardship withdrawals) identified as such on the retirement plan recordkeeper’s system;

· purchase transactions involving in-kind transfers of shares of the fund, rollovers, Roth IRA conversions and IRA recharacterizations, if the entity maintaining the shareholder account is able to identify the transaction as one of these types of transactions;

· transactions by certain intermediaries in accordance with established hedging programs approved by the fund’s investment adviser; and

· systematic redemptions and purchases, if the entity maintaining the shareholder account is able to identify the transaction as a systematic redemption or purchase.

Generally, purchases and redemptions will not be considered “systematic” unless the transaction is prescheduled for a specific date.

American Funds Service Company will work with certain intermediaries (such as investment dealers holding shareholder accounts in street name, retirement plan recordkeepers, insurance company separate accounts and bank trust companies) to apply their own procedures, provided that American Funds Service Company believes the intermediary’s procedures are reasonably designed to enforce the frequent trading policies of the fund. You should refer to disclosures provided by the intermediaries with

The Income Fund of America / Prospectus 28

which you have an account to determine the specific trading restrictions that apply to you.

If American Funds Service Company 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. If American Funds Service Company is not satisfied that the intermediary has taken appropriate action, American Funds Service Company may terminate the intermediary’s ability to transact in fund shares.

There is no guarantee that all instances of frequent trading in fund shares will be prevented.

Notwithstanding the fund’s surveillance procedures described above, all transactions in fund shares remain subject to the right of the fund, Capital Client Group, Inc. and American Funds Service Company to restrict potentially abusive trading generally, including the types of transactions described above that will not be prevented. See the statement of additional information for more information about how American Funds Service Company may address other potentially abusive trading activity in American Funds.

Distributions and taxes

Dividends and distributions The fund intends to distribute dividends to you, usually in March, June, September and December.

Capital gains, if any, are usually distributed in December. When a dividend or capital gain is distributed, the net asset value per share is reduced by the amount of the payment.

You may elect to reinvest dividends and/or capital gain distributions to purchase additional shares of this fund or other American Funds, or you may elect to receive them in cash. Dividends and capital gain distributions for 529 share classes and retirement plan shareholders will be reinvested automatically.

Taxes on dividends and distributions For federal tax purposes, dividends and distributions of short-term capital gains are taxable as ordinary income. If you are an individual and meet certain holding period requirements with respect to your fund shares, you may be eligible for reduced tax rates on “qualified dividend income,” if any, distributed by the fund to you. The fund’s distributions of net long-term capital gains are taxable as long-term capital gains. Any dividends or capital gain distributions you receive from the fund will normally be taxable to you when made, regardless of whether you reinvest dividends or capital gain distributions or receive them in cash.

Dividends and capital gain distributions that are automatically reinvested in a tax-favored retirement or education savings account do not result in federal or state income tax at the time of reinvestment.

Taxes on transactions Your redemptions, including exchanges, may result in a capital gain or loss for federal tax purposes. A capital gain or loss on your investment is the difference between the cost of your shares, including any sales charges, and the amount you receive when you sell them.

Exchanges within a tax-favored retirement plan account will not result in a capital gain or loss for federal or state income tax purposes. With limited exceptions, distributions from a retirement plan account are taxable as ordinary income.

Shareholder fees Fees borne directly by the fund normally have the effect of reducing a shareholder’s taxable income on distributions.

Please see your tax advisor for more information. Holders of Class 529 shares should refer to the applicable program description for more information regarding the tax consequences of selling Class 529 shares.

The Income Fund of America / Prospectus 30

Choosing a share class The fund offers different classes of shares through this prospectus. The services or share classes available to you may vary depending upon how you wish to purchase shares of the fund.

Each share class represents an investment in the same portfolio of securities, but each class has its own sales charge and expense structure, allowing you to choose the class that best fits your situation. For example, while Class F-1 shares are subject to 12b-1 fees and subtransfer agency fees payable to third-party service providers, Class F-2 shares are subject only to subtransfer agency fees payable to third-party service providers (and not 12b-1 fees) and Class F-3 shares are not subject to any such additional fees. The different fee structures allow the investor to choose how to pay for advisory platform expenses. Class R shares offer different levels of 12b-1 and recordkeeping fees so that a plan can choose the class that best meets the cost associated with obtaining investment related services and participant level recordkeeping for the plan. When you purchase shares of the fund for an individual-type account, you should choose a share class. If none is chosen, your investment will be made in Class A shares or, in the case of a 529 plan investment, Class 529-A shares (or, if you are investing through a financial intermediary who offers only Class T and 529-T shares, your investment will be made in Class T or Class 529-T shares, as applicable).

Factors you should consider when choosing a class of shares include:

· how long you expect to own the shares;

· how much you intend to invest;

· total expenses associated with owning shares of each class;

· whether you qualify for any reduction or waiver of sales charges (for example, Class A or 529-A or Class T or 529-T shares may be a less expensive option over time, particularly if you qualify for a sales charge reduction or waiver);

· whether you want or need the flexibility to effect exchanges among Capital Group Funds without the imposition of a sales charge (for example, while Class A shares offer such exchange privileges, Class T shares do not);

· whether you plan to take any distributions in the near future (for example, the contingent deferred sales charge will not be waived if you sell your Class 529-C shares to cover higher education expenses); and

· availability of share classes:

— Class C shares are not available to retirement plans that do not currently invest in such shares and that are eligible to invest in Class R shares, including retirement plans established under Internal Revenue Code Sections 401(a) (including 401(k) plans), 403(b) or 457;

— Class F and 529-F shares are available, as applicable, (i) to fee-based programs of investment dealers that have special agreements with the fund’s distributor, (ii) to financial intermediaries that have been approved by, and that have special agreements with, the fund’s distributor to offer Class F and 529-F shares to self-directed investment brokerage accounts that may charge a transaction fee, (iii) to certain registered investment advisors and (iv) to other intermediaries approved by the fund’s distributor;

— Class F-3 shares (but not Class 529-F-3 shares) are also available to institutional investors, which include, but are not limited to, charitable organizations, governmental institutions, corporations and financial intermediaries. For accounts

31 The Income Fund of America / Prospectus

held and serviced by the fund’s transfer agent the minimum investment amount is $1 million; and

— Class R shares are available (i) to retirement plans established under Internal Revenue Code Sections 401(a) (including 401(k) plans), 403(b) or 457, (ii) to nonqualified deferred compensation plans and certain voluntary employee benefit association and post-retirement benefit plans, (iii) to certain institutional investors (including, but not limited to, certain charitable organizations), (iv) to certain registered investment companies approved by the fund’s investment adviser or distributor and (v) to other institutional-type accounts.

Each investor’s financial considerations are different. You should speak with your financial professional to help you decide which share class is best for you.

The Income Fund of America / Prospectus 32

Sales charges

Class A and 529-A shares The initial sales charge you pay each time you buy Class A or 529-A shares differs depending upon the amount you invest and may be reduced or eliminated for larger purchases as indicated below. The “offering price,” the price you pay to buy shares, includes any applicable sales charge, which will be deducted directly from your investment. Shares acquired through reinvestment of dividends or capital gain distributions are not subject to an initial sales charge.

Class A shares


	Sales charge as a percentage of:
Investment	Offering price	Net amount invested	Dealer commission as a percentage of offering price
Less than $25,000	5.75%	6.10%	5.00%
$25,000 but less than $50,000	5.00	5.26	4.25
$50,000 but less than $100,000	4.50	4.71	3.75
$100,000 but less than $250,000	3.50	3.63	2.75
$250,000 but less than $500,000	2.50	2.56	2.00
$500,000 but less than $750,000	2.00	2.04	1.60
$750,000 but less than $1 million	1.50	1.52	1.20
$1 million or more and certain other investments described below	none	none	see below

Class 529-A shares


	Sales charge as a percentage of:
Investment	Offering price	Net amount invested	Dealer commission as a percentage of offering price
Less than $250,000	3.50%	3.63%	2.75%
$250,000 but less than $500,000	2.50	2.56	2.00
$500,000 but less than $750,000	2.00	2.04	1.60
$750,000 but less than $1 million	1.50	1.52	1.20
$1 million or more and certain other investments described below	none	none	see below

The sales charge, expressed as a percentage of the offering price or the net amount invested, may be higher or lower than the percentages described in the table above due to rounding. This is because the dollar amount of the sales charge is determined by subtracting the net asset value of the shares purchased from the offering price, which is calculated to two decimal places using standard rounding criteria. The impact of rounding will vary with the size of the investment and the net asset value of the shares. Similarly, any contingent deferred sales charge paid by you on investments in Class A or 529-A shares may be higher or lower than the 1% charge described below due to rounding.

33 The Income Fund of America / Prospectus

Except as provided below, investments in Class A shares of $1 million or more will be subject to a 1% contingent deferred sales charge if the shares are sold within 18 months of purchase. The contingent deferred sales charge is based on the original purchase cost or the current market value of the shares being sold, whichever is less.

Class A share purchases not subject to sales charges The following investments are not subject to any initial or contingent deferred sales charge if American Funds Service Company is properly notified of the nature of the investment:

· investments made by accounts that are part of qualified fee-based programs that purchased Class A shares before the discontinuation of the relevant investment dealer’s load-waived Class A share program with American Funds and that continue to be held through fee-based programs;

· rollover investments from retirement plans to IRAs that are described in the “Rollovers from retirement plans to IRAs” section of this prospectus;

· investments made by accounts held at American Funds Service Company that are no longer associated with a financial professional may invest in Class A shares without a sales charge. This includes retirement plans investing in Class A shares, where the plan is no longer associated with a financial professional. SIMPLE IRAs and 403(b) custodial accounts that are aggregated at the plan level for Class A sales charge purposes are not eligible to invest without a sales charge under this policy; and

· Investments made by accounts held through banks and bank trust companies that charge a fee for custodial services and do not have a financial professional assigned to the account.

The distributor may pay dealers a commission of up to 1% on investments made in Class A shares with no initial sales charge. The fund may reimburse the distributor for these payments through its plans of distribution (see “Plans of distribution” in this prospectus).

A transfer from the Virginia Prepaid Education Program^SM or the Virginia Education Savings Trust^SM to a CollegeAmerica^® account will be made with no sales charge. No commission will be paid to the dealer on such a transfer. Investment dealers will be compensated solely with an annual service fee that begins to accrue immediately.

If requested, American Funds Class A shares will be sold at net asset value to:

35 The Income Fund of America / Prospectus

Class T shares The initial sales charge you pay each time you buy Class T shares differs depending upon the amount you invest and may be reduced for larger purchases as indicated below. The “offering price,” the price you pay to buy shares, includes any applicable sales charge, which will be deducted directly from your investment.

See “Plans of distribution” in this prospectus for ongoing compensation paid to your financial professional for all share classes.

Contingent deferred sales charges Shares acquired through reinvestment of dividends or capital gain distributions are not subject to a contingent deferred sales charge. In addition, the contingent deferred sales charge may be waived in certain circumstances. See “Contingent deferred sales charge waivers” in the “Sales charge reductions and waivers” section of this prospectus.

The Income Fund of America / Prospectus 36

Sales charge reductions and waivers To receive a reduction in your Class A initial sales charge, you must let your financial professional or American Funds Service Company know at the time you purchase shares that you qualify for such a reduction. If you do not let your financial professional or American Funds Service Company know that you are eligible for a reduction, you may not receive the sales charge discount to which you are otherwise entitled. In order to determine your eligibility to receive a sales charge discount, it may be necessary for you to provide your financial professional or American Funds Service Company with information and records (including account statements) of all relevant accounts invested in eligible shares of Capital Group Funds. You may need to invest directly through American Funds Service Company in order to receive the sales charge waivers described in this prospectus. Investors should consult their financial intermediary for further information. Certain financial intermediaries that distribute shares of American Funds may impose different sales charge waivers than those described in this prospectus. Such variations in sales charge waivers are described in an appendix to this prospectus titled “Sales charge waivers.” Note that such sales charge waivers and discounts offered through a particular intermediary, as set forth in the appendix to this prospectus, are implemented and administered solely by that intermediary. Please contact the applicable intermediary to ensure that you understand the steps you must take in order to qualify for any available waivers or discounts.

In addition to the information in this prospectus, you may obtain more information about share classes, sales charges and sales charge reductions and waivers through a link on the home page of our website at capitalgroup.com, from the statement of additional information or from your financial professional.

Reducing your Class A initial sales charge Consistent with the policies described in this prospectus, you and your “immediate family” (your spouse — or equivalent, if recognized under local law, your children under the age of 21 or disabled adult dependents covered by ABLE accounts) may combine all of your Capital Group Funds investments to reduce Class A sales charges. In addition, two or more retirement plans of an employer or an employer’s affiliates may combine all of their Capital Group Funds investments to reduce Class A sales charges. However, for this purpose, investments representing direct purchases of American Funds U.S. Government Money Market Fund Class A shares are excluded. Following are different ways that you may qualify for a reduced Class A sales charge:

Aggregating accounts To receive a reduced Class A sales charge, investments in Capital Group Funds made by you and your immediate family (see above) may be aggregated if made for your own account(s) and/or certain other accounts, such as:

· individual-type employee benefit plans, such as an IRA, single-participant Keogh-type plan, or a participant account of a 403(b) plan that is treated as an individual-type plan for sales charge purposes (see “Purchases by certain 403(b) plans” under “Rollovers from retirement plans to IRAs” below);

· SEP plans and SIMPLE IRA plans established after November 15, 2004, by an employer adopting any plan document other than a prototype plan produced by Capital Client Group, Inc.;

· business accounts solely controlled by you or your immediate family (for example, you own the entire business);

37 The Income Fund of America / Prospectus

· trust accounts established by you or your immediate family (for trusts with only one primary beneficiary, upon the trustor’s death the trust account may be aggregated with such beneficiary’s own accounts; for trusts with multiple primary beneficiaries, upon the trustor’s death the trustees of the trust may instruct American Funds Service Company to establish separate trust accounts for each primary beneficiary; each primary beneficiary’s separate trust account may then be aggregated with such beneficiary’s own accounts);

· endowments or foundations established and controlled by you or your immediate family; or

· 529 accounts, which will be aggregated at the account owner level (Class 529-E accounts may only be aggregated with an eligible employer plan).

Individual purchases by a trustee(s) or other fiduciary(ies) may also be aggregated if the investments are:

· for a single trust estate or fiduciary account, including employee benefit plans other than the individual-type employee benefit plans described above;

· made for two or more employee benefit plans of a single employer or of affiliated employers as defined in the 1940 Act, excluding the individual-type employee benefit plans described above;

· for a diversified common trust fund or other diversified pooled account not specifically formed for the purpose of accumulating fund shares;

· for nonprofit, charitable or educational organizations, or any endowments or foundations established and controlled by such organizations, or any employer-sponsored retirement plans established for the benefit of the employees of such organizations, their endowments, or their foundations;

· for participant accounts of a 403(b) plan that is treated as an employer-sponsored plan for sales charge purposes (see “Purchases by certain 403(b) plans” under “Rollovers from retirement plans to IRAs” below), or made for participant accounts of two or more such plans, in each case of a single employer or affiliated employers as defined in the 1940 Act; or

· for a SEP or SIMPLE IRA plan established after November 15, 2004, by an employer adopting a prototype plan produced by Capital Client Group, Inc.

Purchases made for nominee or street name accounts (securities held in the name of an investment dealer or another nominee such as a bank trust department instead of the customer) may not be aggregated with those made for other accounts and may not be aggregated with other nominee or street name accounts unless otherwise qualified as described above.

Joint accounts may be aggregated with other accounts belonging to the primary owner and/or his or her immediate family. The primary owner of a joint account is the individual responsible for taxes on the account.

Investments made through employer-sponsored retirement plan accounts will not be aggregated with individual-type accounts.

Class A-2 shares of Capital Group KKR Public-Private+ Funds are not eligible for aggregation with shares of the American Funds or Emerging Markets Equities Fund, Inc.

The Income Fund of America / Prospectus 38

Concurrent purchases You may reduce your Class A sales charge by combining simultaneous purchases (including, upon your request, purchases for gifts) of all eligible classes of shares in Capital Group Funds. Shares of American Funds U.S. Government Money Market Fund purchased through an exchange, reinvestment or cross-reinvestment from a fund having a sales charge also qualify. However, direct purchases of American Funds U.S. Government Money Market Fund Class A shares are excluded. If you currently have individual holdings in American Legacy variable annuity contracts or variable life insurance policies that were established on or before March 31, 2007, you may continue to combine purchases made under such contracts and policies to reduce your Class A sales charge.

Rights of accumulation Subject to the limitations described in the aggregation policy, you may take into account your accumulated holdings in all eligible share classes of Capital Group Funds to determine your sales charge on investments in accounts eligible to be aggregated. Direct purchases of American Funds U.S. Government Money Market Fund Class A shares are excluded. Subject to your investment dealer’s or recordkeeper’s capabilities, your accumulated holdings will be calculated as the higher of (a) the current value of your existing holdings (the “market value”) as of the day prior to your American Funds investment or (b) the amount you invested (including reinvested dividends and capital gains, but excluding capital appreciation) less any withdrawals (the “cost value”). Depending on the entity on whose books your account is held, the value of your holdings in that account may not be eligible for calculation at cost value. For example, accounts held in nominee or street name may not be eligible for calculation at cost value and instead may be calculated at market value for purposes of rights of accumulation.

The value of all of your holdings in accounts established in calendar year 2005 or earlier will be assigned an initial cost value equal to the market value of those holdings as of the last business day of 2005. Thereafter, the cost value of such accounts will increase or decrease according to actual investments or withdrawals. You must contact your financial professional or American Funds Service Company if you have additional information that is relevant to the calculation of the value of your holdings.

When determining your American Funds Class A sales charge, if your investment is not in an employer-sponsored retirement plan, you may also continue to take into account the market value (as of the day prior to your American Funds investment) of your individual holdings in various American Legacy variable annuity contracts and variable life insurance policies that were established on or before March 31, 2007. An employer-sponsored retirement plan may also continue to take into account the market value of its investments in American Legacy Retirement Investment Plans that were established on or before March 31, 2007.

You may not purchase Class C or 529-C shares if such combined holdings cause you to be eligible to purchase Class A or 529-A shares at the $1 million or more sales charge discount rate (i.e., at net asset value).

If you make a gift of American Funds Class A shares, upon your request, you may purchase the shares at the sales charge discount allowed under rights of accumulation of all of your Capital Group Funds and applicable American Legacy accounts.

You should retain any records necessary to substantiate the historical amounts you have invested.

39 The Income Fund of America / Prospectus

Statement of intention You may reduce your Class A sales charge by establishing a statement of intention. A statement of intention is a nonbinding commitment that allows you to combine all purchases of all eligible Capital Group Funds share classes (excluding American Funds U.S. Government Money Market Fund) that you intend to make over a 13-month period to determine the applicable sales charge; however, purchases made under a right of reinvestment, appreciation of your holdings, and reinvested dividends and capital gains do not count as purchases made during the statement period. Your accumulated holdings (as described and calculated under “Rights of accumulation” above) eligible to be aggregated as of the day immediately before the start of the statement period may be credited toward satisfying the statement. A portion of your account may be held in escrow to cover additional Class A sales charges that may be due if your total purchases over the statement period do not qualify you for the applicable sales charge reduction. Employer-sponsored retirement plans are restricted from establishing statements of intention. See the discussion regarding employer-sponsored retirement plans under “Purchase, exchange and sale of shares” in this prospectus for more information.

The statement of intention period starts on the date on which your first purchase made toward satisfying the statement of intention is processed. Your accumulated holdings (as described above under “Rights of accumulation”) eligible to be aggregated as of the day immediately before the start of the statement of intention period may be credited toward satisfying the statement of intention.

You may revise the commitment you have made in your statement of intention upward at any time during the statement of intention period. If your prior commitment has not been met by the time of the revision, the statement of intention period during which purchases must be made will remain unchanged. Purchases made from the date of the revision will receive the reduced sales charge, if any, resulting from the revised statement of intention. If your prior commitment has been met by the time of the revision, your original statement of intention will be considered met and a new statement of intention will be established.

The statement of intention will be considered completed if the shareholder dies within the 13-month statement of intention period. Commissions to dealers will not be adjusted or paid on the difference between the statement of intention amount and the amount actually invested before the shareholder’s death.

When a shareholder elects to use a statement of intention, shares equal to 5% of the dollar amount specified in the statement of intention may be held in escrow in the shareholder’s account out of the initial purchase (or subsequent purchases, if necessary) by American Funds Service Company. All dividends and any capital gain distributions on shares held in escrow will be credited to the shareholder’s account in shares (or paid in cash, if requested). If the intended investment is not completed within the specified statement of intention period the investments made during the statement period will be adjusted to reflect the difference between the sales charge actually paid and the sales charge which would have been paid if the total of such purchases had been made at a single time. Any dealers assigned to the shareholder’s account at the time a purchase was made during the statement period will receive a corresponding commission adjustment if appropriate.

The Income Fund of America / Prospectus 40

In addition, if you currently have individual holdings in American Legacy variable annuity contracts or variable life insurance policies that were established on or before March 31, 2007, you may continue to apply purchases under such contracts and policies to a statement of intention.

Shareholders purchasing shares at a reduced sales charge under a statement of intention indicate their acceptance of these terms and those in the prospectus with their first purchase.

Reducing your Class T initial sales charge Consistent with the policies described in this prospectus, the initial sales charge you pay each time you buy Class T shares may differ depending upon the amount you invest and may be reduced for larger purchases. Additionally, Class T shares acquired through reinvestment of dividends or capital gain distributions are not subject to an initial sales charge. Sales charges on Class T shares are applied on a transaction-by-transaction basis, and, accordingly, Class T shares are not eligible for any other sales charge waivers or reductions, including through the aggregation of Class T shares concurrently purchased by other related accounts or in other American Funds. The sales charge applicable to Class T shares may not be reduced by establishing a statement of intention, and rights of accumulation are not available for Class T shares.

Right of reinvestment If you notify American Funds Service Company prior to the time of reinvestment, you may reinvest proceeds from a redemption, dividend payment or capital gain distribution without a sales charge in the same fund or other American Funds or Capital Group KKR Public-Private+ Funds, provided that the reinvestment occurs within 90 days after the date of the redemption, dividend payment or distribution and is made into the same account from which you redeemed the shares or received the dividend payment or distribution. If the account has been closed, you may reinvest without a sales charge if the new receiving account has the same registration as the closed account and the reinvestment is made within 90 days after the date of redemption, dividend payment or distribution.

Proceeds from a redemption and all dividend payments and capital gain distributions will be reinvested in the same share class from which the original redemption, dividend payment or distribution was made. Any contingent deferred sales charge on Class A or C shares will be credited to your account. Redemption proceeds of Class A shares representing direct purchases in American Funds U.S. Government Money Market Fund that are reinvested in other American Funds or Capital Group KKR Public-Private+ Funds will be subject to a sales charge.

Proceeds will be reinvested at the next calculated net asset value after your request is received by American Funds Service Company, provided that your request contains all information and legal documentation necessary to process the transaction. For purposes of this “right of reinvestment policy,” automatic transactions (including, for example, automatic purchases, withdrawals and payroll deductions) and ongoing retirement plan contributions are not eligible for investment without a sales charge. This paragraph does not apply to certain rollover investments as described under “Rollovers from retirement plans to IRAs” in this prospectus. Depending on the financial intermediary holding your account, your reinvestment privileges may be unavailable or differ from those described in this prospectus. Investors should consult their financial intermediary for further information.

Contingent deferred sales charge waivers The contingent deferred sales charge on Class A and C shares will be waived in the following cases:

· permitted exchanges of shares, except if shares acquired by exchange are then redeemed within the period during which a contingent deferred sales charge would apply to the initial shares purchased;

· tax-free returns of excess contributions to IRAs;

· redemptions due to death or postpurchase disability of the shareholder (this generally excludes accounts registered in the names of trusts and other entities);

· in the case of joint tenant accounts, if one joint tenant dies, a surviving joint tenant, at the time he or she notifies American Funds Service Company of the other joint tenant’s death and removes the decedent’s name from the account, may redeem shares from the account without incurring a contingent deferred sales charge; however, redemptions made after American Funds Service Company is notified of the death of a joint tenant will be subject to a contingent deferred sales charge;

· for 529 share classes only, redemptions due to a beneficiary’s death, postpurchase disability or receipt of a scholarship (to the extent of the scholarship award);

· redemptions due to the complete termination of a trust upon the death of the trustor/grantor or beneficiary, but only if such termination is specifically provided for in the trust document;

· shares redeemed at the discretion of American Funds Service Company for accounts that do not meet the fund’s minimum investment requirements, as described in this prospectus; and

· the following types of transactions, if they do not exceed 12% of the value of an account annually:

— required minimum distributions taken from retirement accounts in accordance with IRS regulations; and

— redemptions through an automatic withdrawal plan (“AWP”) (see “Automatic withdrawals” under “Shareholder account services and privileges” in the statement of additional information). For each AWP payment, assets that are not subject to a contingent deferred sales charge, such as shares acquired through reinvestment of dividends and/or capital gain distributions, will be redeemed first and will count toward the 12% limit. If there is an insufficient amount of assets not subject to a contingent deferred sales charge to cover a particular AWP payment, shares subject to the lowest contingent deferred sales charge will be redeemed next until the 12% limit is reached. Any dividends and/or capital gain distributions taken in cash by a shareholder who receives payments through an AWP will also count toward the 12% limit. In the case of an AWP, the 12% limit is calculated at the time an automatic redemption is first made, and is recalculated at the time each additional automatic redemption is made. Shareholders who establish an AWP should be aware that the amount of a payment not subject to a contingent deferred sales charge may vary over time depending on fluctuations in the value of their accounts. This privilege may be revised or terminated at any time.

For purposes of this paragraph, “account” means your investment in the applicable class of shares of the particular fund from which you are making the redemption.

The Income Fund of America / Prospectus 42

The contingent deferred sales charge on American Funds Class A shares may be waived in cases where the fund’s transfer agent determines the benefit to the fund of collecting the contingent deferred sales charge would be outweighed by the cost of applying it.

Contingent deferred sales charge waivers are allowed only in the cases listed here and in the statement of additional information. For example, contingent deferred sales charge waivers will not be allowed on redemptions of Class 529-C shares due to termination of CollegeAmerica; a determination by the Internal Revenue Service that CollegeAmerica does not qualify as a qualified tuition program under the Code; proposal or enactment of law that eliminates or limits the tax-favored status of CollegeAmerica; or elimination of the fund by Commonwealth Savers Plan^SM (formerly, Virginia529) as an option for additional investment within CollegeAmerica.

To have your Class A or C contingent deferred sales charge waived, you must inform your financial professional or American Funds Service Company at the time you redeem shares that you qualify for such a waiver.

Other sales charge waivers Purchases of Class A shares through a self-clearing broker-dealer firm generally incur a sales charge. However, self-clearing broker-dealer firms may extend the 90 day right of reinvestment to allow reinvestment in Class A shares without a sales charge in cases where fund shareholders request reinvestment of a required minimum distribution from an Individual Retirement Account if such requirement is waived by regulation or legislation (“waived RMD reinvestment”), provided that the self-clearing broker-dealer firm has specific language in this prospectus to such effect. If a self-clearing firm does not have their own policies listed in the prospectus, waived RMD reinvestments are not available without a sales charge. Firm specific language is located in the appendix to the prospectus. A self-clearing broker-dealer firm is a firm that holds some or all of the assets in your account, executes trades for the assets held on its platform internally rather than through the fund’s transfer agent or a third-party clearing firm and provides account statements and tax reporting to you. The largest broker-dealer firms are typically self-clearing. For all other broker-dealer firms, shares purchased through a waived RMD reinvestment are available at net asset value. For accounts held with the fund’s transfer agent, waived RMD reinvestments in Class A shares are not subject to sales charges.

Purchases of Class 529-A shares through (i) a rollover from another 529 plan or (ii) a recontribution of a refunded qualified education expense are not subject to sales charges.

If you have any questions, ask your financial professional whether Class A or 529-A shares purchased through these policies are available without a sales charge. Recontributions or waived RMD investments distributed from Class 529-C or Class C shares will be reinvested in the same share class from which the distribution was made. In addition, any contingent deferred sales charge paid on Class 529-A/Class A and Class 529-C/Class C share distributions under these policies will be credited to your account when reinvested.

Waivers of all or a portion of the contingent deferred sales charge on Class C and 529-C shares and the sales charge on Class A and 529-A shares will be granted for transactions requested by financial intermediaries as a result of (i) pending or anticipated regulatory matters that require investor accounts to be moved to a different share class or (ii) conversions of IRAs from brokerage to advisory accounts investing in Class F shares in

43 The Income Fund of America / Prospectus

cases where new investments in brokerage IRA accounts have been restricted by the intermediary.

Rollovers from CollegeAmerica to Roth IRAs Proceeds of a CollegeAmerica plan account may be rolled over in a direct trustee-to-trustee transfer to the plan beneficiary’s Capital Bank and Trust Roth IRA and invested in Class A shares without a sales charge, provided that such rollover is intended to satisfy the requirements of the Internal Revenue Code. If you hold CollegeAmerica or Roth IRA accounts through a financial intermediary its policies may differ.

Rollovers from retirement plans to IRAs Assets from retirement plans may be invested in Class A, C or F shares through an IRA rollover, subject to the other provisions of this prospectus. Class C shares are not available if the assets are being rolled over from investments held in American Funds Recordkeeper Direct and PlanPremier retirement plan recordkeeping programs.

Rollovers to IRAs from retirement plans that are rolled into Class A shares will be subject to applicable sales charges. The following rollovers to Class A shares will be made without a sales charge:

· rollovers to IRAs with Capital Bank and Trust Company as custodian if the assets were invested in any fund managed by the investment adviser or its affiliates at the time of distribution;

· rollovers to IRAs from 403(b) plans with Capital Bank and Trust Company as custodian;

· rollovers to IRAs with Capital Bank and Trust Company as custodian from investments held in American Funds Recordkeeper Direct and PlanPremier retirement plan recordkeeping programs; and

· rollovers to IRAs with Capital Bank and Trust Company as custodian if at the time of distribution the assets were invested in any fund or account with a name that includes American Funds, Capital Group, or the name of a fund managed by the investment adviser or its affiliates and such fund or account was established pursuant to an agreement with the investment adviser or its affiliates.

IRA rollover assets that roll over without a sales charge as described above will not be subject to a contingent deferred sales charge, and investment dealers will be compensated solely with an annual service fee that begins to accrue immediately. All other rollovers invested in Class A shares, as well as future contributions to the IRA, will be subject to sales charges and to the terms and conditions generally applicable to Class A share investments as described in this prospectus and in the statement of additional information.

Purchases by SEP plans and SIMPLE IRA plans Participant accounts in a Simplified Employee Pension (SEP) plan or a Savings Incentive Match Plan for Employees of Small Employers IRA (SIMPLE IRA) will be aggregated at the plan level for Class A sales charge purposes if an employer adopts a prototype plan produced by Capital Client Group, Inc. or (a) the employer or plan sponsor submits all contributions for all participating employees in a single contribution transmittal or the contributions are identified as related to the same plan; (b) each transmittal is accompanied by checks or wire transfers and generally must be submitted through the transfer agent’s automated contribution system if held on the fund’s books; and (c) if the fund is expected to carry separate accounts in the name of each plan participant and (i) the employer or plan sponsor notifies the funds’ transfer agent or the intermediary holding the account that the separate accounts of all plan participants should be linked and (ii) all new participant

The Income Fund of America / Prospectus 44

accounts are established by submitting the appropriate documentation on behalf of each new participant. Participant accounts in a SEP or SIMPLE plan that are eligible to aggregate their assets at the plan level may not also aggregate the assets with their individual accounts.

Purchases by certain 403(b) plans A 403(b) plan may not invest in American Funds Class A or C shares unless such plan was invested in Class A or C shares before January 1, 2009.

Participant accounts of a 403(b) plan that invested in American Funds Class A or C shares and were treated as an individual-type plan for sales charge purposes before January 1, 2009, may continue to be treated as accounts of an individual-type plan for sales charge purposes. Participant accounts of a 403(b) plan that invested in American Funds Class A or C shares and were treated as an employer-sponsored plan for sales charge purposes before January 1, 2009, may continue to be treated as accounts of an employer-sponsored plan for sales charge purposes. Participant accounts of a 403(b) plan that was established on or after January 1, 2009, are treated as accounts of an employer-sponsored plan for sales charge purposes.

Moving between accounts American Funds investments by certain account types may be moved to other account types without incurring additional Class A sales charges. These transactions include:

· redemption proceeds from a non-retirement account (for example, a joint tenant account) used to purchase fund shares in an IRA or other individual-type retirement account;

· required minimum distributions from an IRA or other individual-type retirement account used to purchase fund shares in a non-retirement account; and

· death distributions paid to a beneficiary’s account that are used by the beneficiary to purchase fund shares in a different account.

These privileges are generally available only if your account is held directly with the fund’s transfer agent or if the financial intermediary holding your account has the systems, policies and procedures to support providing the privileges on its systems. Investors should consult their financial intermediary for further information.

45 The Income Fund of America / Prospectus

Plans of distribution The fund has plans of distribution, or “12b-1 plans,” for certain share classes under which it may finance activities intended primarily to sell shares, provided that the categories of expenses are approved in advance by the fund’s board of trustees. The plans provide for payments, based on annualized percentages of average daily net assets, of:


Up to:	Share class(es)
0.25%	Class A shares
0.50%	Class T, F-1, 529-A, 529-T, 529-F-1 and R-4 shares
0.75%	Class 529-E and R-3 shares
0.85%	Class R-2E shares
1.00%	Class C, 529-C, R-1 and R-2 shares

For all share classes indicated above, up to .25% may be used to pay service fees to qualified dealers for providing certain shareholder services. The amount remaining for each share class, if any, may be used for distribution expenses.

The 12b-1 fees paid by each applicable share class of the fund, as a percentage of average net assets for the most recent fiscal year, are indicated in the Annual Fund Operating Expenses table under “Fees and expenses of the fund” in this prospectus. Since these fees are paid out of the fund’s assets on an ongoing basis, over time they may cost you more than paying other types of sales charges or service fees and reduce the return on your investment. The higher fees for Class C shares may cost you more over time than paying the initial sales charge for Class A or T shares.

The Income Fund of America / Prospectus 46

Other compensation to dealers Capital Client Group, Inc., at its expense, provides additional compensation to investment dealers. These payments may be made, at the discretion of Capital Client Group, Inc., to no more than the top 60 dealers (or their affiliates) with which it has a substantive distribution relationship involving the sale of American Funds. The amount will be determined using a formula applied consistently to dealers based on their assets under management. The level of payments made to a qualifying firm under the formula will not exceed .035% of eligible American Funds assets attributable to that dealer. Eligible assets are all American Funds assets other than Class R shares, Class F-3 shares, Class F shares held in IRAs and shares held in certain retirement accounts. Dealers may direct Capital Client Group, Inc. to exclude additional assets. In addition to the asset-based payment, Capital Client Group, Inc. provides $5 million to certain firms based on their engagement with Capital Client Group, Inc. and the level of American Funds assets under management at each such firm to recognize the commitment each of those firms has made to collaborating with Capital Client Group, Inc. on achieving advisor training and education objectives. In the prior calendar year, Capital Client Group, Inc. paid this amount to the following firms:


Edward Jones	Morgan Stanley Wealth Management
LPL Financial LLC	Raymond James Group
Merrill Lynch, Pierce, Fenner & Smith	Wells Fargo Advisors

Capital Client Group, Inc. compensates the firms to support various efforts, including, among other things, to:

· help defray the costs incurred by qualifying dealers in connection with efforts to educate financial professionals about American Funds so that they can make recommendations and provide services that are suitable and meet shareholder needs;

· help defray the costs associated with the dealer firms’ provision of account related services and activities and support the dealer firms’ distribution activities;

· support meetings, conferences or other training and educational events hosted by the firm, and obtain relevant data regarding financial professional activities to facilitate Capital Client Group, Inc.’s training and education activities; and

· make the American Funds available through firm distribution platforms and related sales infrastructure.

Capital Client Group, Inc. will, on an annual basis, determine the advisability of continuing these payments. Firms receiving additional compensation payments must sign a letter acknowledging the purpose of the payment and generally requiring the firms to (1) perform the due diligence necessary to include American Funds on their platform, (2) not provide financial professionals, branch managers or associated persons with any financial incentives to promote the sales of one approved fund group over another approved group, (3) provide opportunities for their clients to obtain individualized advice, (4) provide Capital Client Group, Inc. broad access to their financial professionals and product platforms and work together on mutual business objectives, and (5) work with the fund’s transfer agent to promote operational efficiencies and to facilitate necessary communication between American Funds and the firm’s clients who own shares of American Funds.

47 The Income Fund of America / Prospectus

Separately, Capital Client Group, Inc. makes payments to certain financial intermediaries and other firms for services including:

· making the American Funds available through firm distribution platforms including self-directed platforms for the public as well as clearing, custody and recordkeeping services for other intermediaries and related sales infrastructure;

· account maintenance and support, statement preparation, transaction processing and operational improvements; and

· training, education and marketing opportunities, support for transaction fees, technology costs and data (including fees to obtain information on financial professionals to better tailor training, education and marketing opportunities).

A list of firms receiving additional compensation (as described above) in an amount exceeding $100,000 in the prior calendar year is included in the statement of additional information.

Capital Client Group, Inc. pays certain recordkeepers for product services, platform consideration, participation at recordkeeper-sponsored events and co-branding and other marketing services. A list of recordkeepers receiving additional compensation (as described above) in an amount exceeding $100,000 in the prior calendar year is included in the statement of additional information.

If investment advisers, distributors or other affiliates of mutual funds pay additional compensation or other incentives to investment dealers in differing amounts, dealer firms and their financial professionals may have financial incentives for recommending a particular mutual fund over other mutual funds or investments, creating a potential conflict of interest. You should consult with your financial professional and review carefully any disclosure by your financial professional’s firm as to compensation received.

Fund expenses Note that, unless otherwise stated, references to Class A, C, T and F shares in this “Fund expenses” section do not include the corresponding Class 529 shares.

In periods of market volatility, assets of the fund may decline significantly, causing total annual fund operating expenses (as a percentage of the value of your investment) to become higher than the numbers shown in the Annual Fund Operating Expenses table under “Fees and expenses of the fund” in this prospectus.

For all share classes, “Other expenses” items in the Annual Fund Operating Expenses table in this prospectus include fees for administrative services provided by the fund’s investment adviser and its affiliates. Administrative services are provided by the investment adviser and its affiliates to help assist third parties providing non-distribution services to fund shareholders. These services include providing in-depth information on the fund and market developments that impact fund investments. Administrative services also include, but are not limited to, coordinating, monitoring and overseeing third parties that provide services to fund shareholders. The Administrative Services Agreement between the fund and the investment adviser provides the fund the ability to charge an administrative services fee of .05% for all share classes. The fund’s investment adviser receives an administrative services fee at the annual rate of .03% of the average daily net assets of the fund attributable to Class A, C, T, F, R and 529 shares (which could be increased as noted above) for its provision of administrative services.

The “Other expenses” items in the Annual Fund Operating Expenses table also include custodial, legal and transfer agent (and, if applicable, subtransfer agent/recordkeeping) payments and various other expenses applicable to all share classes.

49 The Income Fund of America / Prospectus

Subtransfer agency and recordkeeping fees Subtransfer agent/recordkeeping payments may be made to third parties (including affiliates of the fund’s investment adviser) that provide subtransfer agent, recordkeeping and/or shareholder services with respect to certain shareholder accounts in lieu of the transfer agent providing such services. The amount paid for subtransfer agent/recordkeeping services varies depending on the share class and services provided, and typically ranges from $3 to $18 per account. Although Class F-3 and Class 529-F-3 shares are not subject to any subtransfer agency or recordkeeping fees, Class F-1 and F-2 shares (and the corresponding Class 529 shares) are subject to subtransfer agency fees of up to .12% of fund assets.

For employer-sponsored retirement plans, the amount paid for subtransfer agent/ recordkeeping services varies depending on the share class selected. The table below shows the maximum payments to entities providing these services to retirement plans.


	Payments
Class A	0.05% of assets or $12 per participant position^*
Class R-1	0.10% of assets
Class R-2	0.35% of assets
Class R-2E	0.20% of assets
Class R-3	0.15% of assets
Class R-4	0.10% of assets
Class R-5E	0.15% of assets
Class R-5	0.05% of assets
Class R-6	none

^* Payment amount depends on the date services commenced.

Fee to Commonwealth Savers Plan For Class 529 shares, an expense of up to a maximum of .09% paid to a state or states for oversight and administrative services is included as an “Other expenses” item.

Financial highlights The Financial Highlights table is intended to help you understand the fund’s results for the past five fiscal years (or, if shorter, the period of operations). Certain information reflects financial results for a single share of a particular class. The total returns in the table represent the rate that an investor would have earned or lost on an investment in the fund (assuming reinvestment of all dividends and capital gain distributions). Where indicated, figures in the table reflect the impact, if any, of certain waivers/reimbursements from Capital Research and Management Company. For more information about these waivers/reimbursements, see the fund’s statement of additional information and Form N-CSR. The information in the Financial Highlights table has been audited by Deloitte & Touche LLP, whose current report, along with the fund’s financial statements, is included in the statement of additional information, which is available upon request.

Appendix

Sales charge waivers

The availability of certain sales charge waivers and discounts will depend on whether you purchase your shares directly from the fund or through a financial intermediary. Intermediaries may have different policies and procedures regarding the availability of front-end sales charge waivers or contingent deferred (back-end) sales charge (“CDSC”) waivers, 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 or discounts. Please contact the applicable intermediary with any questions regarding how the intermediary applies the policies described below and to ensure that you understand what steps you must take to qualify for any available waivers or discounts. For waivers and discounts not available through a particular intermediary, shareholders will have to purchase fund shares directly from the fund or through another intermediary to receive these waivers or discounts. If you change intermediaries after you purchase fund shares, the policies and procedures of the new service provider (either your new intermediary or the fund’s transfer agent) will apply to your account. Those policies may be more or less favorable than those offered by the intermediary through which you purchased your fund shares. You should review any policy differences before changing intermediaries.

Front-end sales charge reductions on Class A shares purchased through Ameriprise Financial

Shareholders purchasing Class A shares of the fund through an Ameriprise Financial platform or account are eligible only for the following sales charge reductions, which may differ from those disclosed elsewhere in this prospectus or the SAI. Such shareholders can reduce their initial sales charge on the purchase of Class A shares as follows:

· Transaction size breakpoints, as described in this prospectus or the SAI

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

Policies Regarding Transactions Through Edward Jones

The following information has been provided by Edward Jones:

Effective on or after January 1, 2024, the following information supersedes prior information with respect to transactions and positions held in fund shares through an Edward Jones system. Clients of Edward Jones (also referred to as “shareholders”) purchasing fund shares on the Edward Jones commission and fee-based platforms are eligible only for the following sales charge discounts (also referred to as “breakpoints”) and waivers, which can differ from discounts and waivers described elsewhere in the mutual fund prospectus or statement of additional information (“SAI”) or through another broker-dealer. In all instances, it is the shareholder's responsibility to inform Edward Jones at the time of purchase of any relationship, holdings of American Funds, or other facts qualifying the purchaser for discounts or waivers. Edward Jones can ask for documentation of such

59 The Income Fund of America / Prospectus

circumstance. Shareholders should contact Edward Jones if they have questions regarding their eligibility for these discounts and waivers.

Breakpoints

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

Rights of Accumulation (“ROA”)

· The applicable sales charge on a purchase of Class A shares is determined by taking into account all share classes (except certain money market funds and any assets held in group retirement plans) of American 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)

Letter of Intent (“LOI”)

· Through a LOI, shareholders can receive the 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

Sales Charge Waivers

Sales charges are waived for the following shareholders and in the following situations:

· Associates of Edward Jones and its affiliates and other accounts 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

The Income Fund of America / Prospectus 60

· Shares purchased in an Edward Jones fee-based program

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

— The redemption and repurchase occur in the same account

— The redemption proceeds are used to process an: IRA contribution, excess contributions, conversion, recharacterizing of contributions, or distribution, and the repurchase is done in an account within the same Edward Jones grouping for ROA

The Right of Reinstatement excludes systematic or automatic transactions including, but not limited to, purchases made through payroll deductions, liquidations to cover account fees, and reinvestments from non-mutual fund products.

· 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

· Purchases of Class 529-A shares through a rollover from either another education savings plan or a security used for qualified distributions

· Purchases of Class 529-A shares made for recontribution of refunded amounts

Contingent Deferred Sales Charge (“CDSC”) Waivers

If the shareholder purchases shares that are subject to a CDSC and those shares are redeemed before the CDSC is expired, the shareholder is responsible to pay the CDSC except in the following conditions:

· The death or disability of the shareholder

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

· Return of excess contributions from an Individual Retirement Account (IRA)

Certain investment limitations and guidelines

The following limitations and guidelines are considered at the time of purchase, under normal circumstances, and are based on a percentage of the fund’s net assets (excluding, for the avoidance of doubt, collateral held in connection with securities lending activities) unless otherwise noted. This summary is not intended to reflect all of the fund’s investment limitations.

Income-producing securities

· The fund will invest at least 65% of its assets in income-producing securities.

Equity securities

· The fund will generally invest at least 60% of its assets in equity securities. However, the composition of the fund’s investments in equity, debt and cash or money market instruments may vary substantially depending on various factors, including market conditions. At times the fund may be substantially invested in equity or debt securities (i.e., more than 60%) or may be solely invested in equity or debt securities (i.e., 100%).

Debt instruments

· The fund may invest up to 20% of its assets in straight debt securities (i.e., debt securities that do not have equity conversion or purchase rights) rated BB+ or below and Ba1 or below by Nationally Recognized Statistical Rating Organizations designated by the fund’s investment adviser or unrated but determined to be of equivalent quality by the fund’s investment adviser.

· The fund currently intends to consider the ratings from Moody’s Investors Service, S&P Global Ratings and Fitch Ratings. If agency ratings of a security differ, the security will be considered to have received the highest of these ratings, consistent with the fund's investment policies.

Investing outside the United States

· The fund may invest up to 30% of its assets in equity securities of issuers domiciled outside the United States.

· The fund may invest up to 10% of its assets in debt securities tied economically to countries outside the United States (must be U.S. dollar denominated).

· For purposes of determining whether an investment is made in a particular country or geographic region, the fund’s investment adviser will generally look to the domicile of the issuer in the case of equity securities or to the country to which the security is tied economically in the case of debt securities. In doing so, the fund’s investment adviser will generally look to the determination of MSCI Inc. (MSCI) for equity securities and Bloomberg for debt securities. In certain limited circumstances (including when relevant data is unavailable or the nature of a holding warrants special considerations), the adviser may also take into account additional factors, as applicable, including where the issuer’s securities are listed; where the issuer is legally organized, maintains principal corporate offices, conducts its principal operations, generates revenues and/or has credit risk exposure; and the source of guarantees, if any, of such securities.

Description of certain securities, investment techniques and risks

The descriptions below are intended to supplement the material in the prospectus under “Investment objectives, strategies and risks.”

Market conditions – The value of, and the income generated by, the securities in which the fund invests may decline, sometimes rapidly or unpredictably, due to factors affecting certain issuers, particular industries or sectors, or the overall markets. Rapid or unexpected changes in market conditions could cause the fund to liquidate holdings at inopportune times or at a loss or depressed value. The value of a particular holding may decrease due to developments related to that issuer, but also due to general market conditions, including real or perceived economic developments such as changes in interest rates, credit quality, inflation, or currency rates or generally adverse investor sentiment. The value of a holding may also decline due to factors that negatively affect a particular industry or sector, such as labor shortages, increased production costs, or competitive conditions.

Global economies and financial markets are highly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. Furthermore, local, regional and global events such as war, acts of terrorism, trading and tariff arrangements, social unrest, natural disasters, the spread of infectious illness or other public health threats, or bank failures could also adversely impact issuers, markets and economies, including in ways that cannot necessarily be foreseen. The fund could be negatively impacted if the value of a portfolio holding were harmed by such conditions or events.

Significant market disruptions, such as those caused by pandemics, natural or environmental disasters, war, acts of terrorism, bank failures or other events, can adversely affect local and global markets and normal market operations. Market disruptions may exacerbate political, social, and economic risks. Additionally, market disruptions may result in increased market volatility; regulatory trading halts; closure of domestic or foreign exchanges, markets, or governments; or market participants operating pursuant to business continuity plans for indeterminate periods of time. Such events can be highly disruptive to economies and markets and significantly impact individual companies, sectors, industries, markets, currencies, interest and inflation rates, credit ratings, investor sentiment, and other factors affecting the value of the fund’s investments and operation of the fund. These events could disrupt businesses that are integral to the fund’s operations or impair the ability of employees of fund service providers to perform essential tasks on behalf of the fund.

Governmental and quasi-governmental authorities may take a number of actions designed to support local and global economies and the financial markets in response to economic disruptions. Such actions may include a variety of significant fiscal and monetary policy changes, including, for example, direct capital infusions into companies, new monetary programs and significantly lower interest rates. These actions have resulted in significant expansion of public debt and may result in greater market risk. Additionally, an unexpected or quick reversal of these policies, or the ineffectiveness of these policies, could negatively impact overall investor sentiment and further increase volatility in securities markets.

Equity securities — Equity securities represent an ownership position in a company. Equity securities held by the fund typically consist of common stocks and may also include securities with equity conversion or purchase rights. The prices of equity securities fluctuate based on, among other things, events specific to their issuers and market, economic and other conditions. For example, prices of these securities can be affected by financial contracts held by the issuer or third parties (such as derivatives) relating to the security or other assets or indices. Holders of equity securities are not creditors of the issuer. If an issuer liquidates, holders of equity securities are entitled to their pro rata share of the issuer’s assets, if any, after creditors (including the holders of fixed income securities and senior equity securities) are paid.

The Income Fund of America — Page 4

There may be little trading in the secondary market for particular equity securities, which may adversely affect the fund’s ability to value accurately or dispose of such equity securities. Adverse publicity and investor perceptions, whether or not based on fundamental analysis, may decrease the value and/or liquidity of equity securities.

The growth-oriented, equity-type securities generally purchased by the fund may involve large price swings and potential for loss. To the extent the fund invests in income-oriented, equity-type securities, income provided by the fund may be reduced by changes in the dividend policies of, and the capital resources available at, the companies in which the fund invests.

Investing in smaller capitalization stocks — The fund may invest in the stocks of smaller capitalization companies. Investing in smaller capitalization stocks can involve greater risk than is customarily associated with investing in stocks of larger, more established companies. For example, smaller companies often have limited product lines, limited operating histories, limited markets or financial resources, may be dependent on one or a few key persons for management and can be more susceptible to losses. Also, their securities may be less liquid or illiquid (and therefore have to be sold at a discount from current prices or sold in small lots over an extended period of time), may be followed by fewer investment research analysts and may be subject to wider price swings, thus creating a greater chance of loss than securities of larger capitalization companies.

Debt instruments — Debt securities, also known as “fixed income securities,” are used by issuers to borrow money. Bonds, notes, debentures, asset-backed securities (including those backed by mortgages), and loan participations and assignments are common types of debt securities. Generally, issuers pay investors periodic interest and repay the amount borrowed either periodically during the life of the security and/or at maturity. Some debt securities, such as zero coupon bonds, do not pay current interest, but are purchased at a discount from their face values and their values accrete over time to face value at maturity. Some debt securities bear interest at rates that are not fixed, but that vary with changes in specified market rates or indices. The market prices of debt securities fluctuate depending on such factors as interest rates, credit quality and maturity. In general, market prices of debt securities decline when interest rates rise and increase when interest rates fall. These fluctuations will generally be greater for longer-term debt securities than for shorter-term debt securities. Prices of these securities can also be affected by financial contracts held by the issuer or third parties (such as derivatives) relating to the security or other assets or indices. Borrowers that are in bankruptcy or restructuring may never pay off their indebtedness, or they may pay only a small fraction of the amount owed. Direct indebtedness of countries, particularly emerging markets, also involves a risk that the governmental entities responsible for the repayment of the debt may be unable, or unwilling, to pay interest and repay principal when due.

Lower rated debt securities, rated Ba1/BB+ or below by Nationally Recognized Statistical Rating Organizations, are described by the rating agencies as speculative and involve greater risk of default or price changes due to changes in the issuer’s creditworthiness than higher rated debt securities, or they may already be in default. Such securities are sometimes referred to as “junk bonds” or high yield bonds. The market prices of these securities may fluctuate more than higher quality securities and may decline significantly in periods of general economic difficulty. It may be more difficult to dispose of, and to determine the value of, lower rated debt securities. Investment grade bonds in the ratings categories A or Baa/BBB also may be more susceptible to changes in market or economic conditions than bonds rated in the highest rating categories.

Certain additional risk factors relating to debt securities are discussed below:

Sensitivity to interest rate and economic changes — Debt securities may be sensitive to economic changes, political and corporate developments, and interest rate changes. In addition, during an economic downturn or a period of rising interest rates, issuers that are

The Income Fund of America — Page 5

highly leveraged may experience increased financial stress that could adversely affect their ability to meet projected business goals, to obtain additional financing and to service their principal and interest payment obligations. Periods of economic change and uncertainty also can be expected to result in increased volatility of market prices and yields of certain debt securities and derivative instruments. As discussed under “Market conditions” above in this statement of additional information, governments and quasi-governmental authorities may take actions to support local and global economies and financial markets during periods of economic crisis, including direct capital infusions into companies, new monetary programs and significantly lower interest rates. Such actions may expose fixed income markets to heightened volatility and may reduce liquidity for certain investments, which could cause the value of the fund’s portfolio to decline.

Payment expectations — Debt securities may contain redemption or call provisions. If an issuer exercises these provisions in a lower interest rate market, the fund may have to replace the security with a lower yielding security, resulting in decreased income to investors. If the issuer of a debt security defaults on its obligations to pay interest or principal or is the subject of bankruptcy proceedings, the fund may incur losses or expenses in seeking recovery of amounts owed to it.

Liquidity and valuation — There may be little trading in the secondary market for particular debt securities, which may affect adversely the fund’s ability to value accurately or dispose of such debt securities. Adverse publicity and investor perceptions, whether or not based on fundamental analysis, may decrease the value and/or liquidity of debt securities.

Credit ratings for debt securities provided by rating agencies reflect an evaluation of the safety of principal and interest payments, not market value risk. The rating of an issuer is a rating agency’s view of past and future potential developments related to the issuer and may not necessarily reflect actual outcomes. There can be a lag between the time of developments relating to an issuer and the time a rating is assigned and updated. The investment adviser considers these ratings of securities as one of many criteria in making its investment decisions.

Bond rating agencies may assign modifiers (such as +/–) to ratings categories to signify the relative position of a credit within the rating category. Investment policies that are based on ratings categories should be read to include any security within that category, without giving consideration to the modifier except where otherwise provided. See the appendix to this statement of additional information for more information about credit ratings.

Securities with equity and debt characteristics — Certain securities have a combination of equity and debt characteristics. Such securities may at times behave more like equity than debt or vice versa.

Preferred stock — Preferred stock represents an equity interest in an issuer that generally entitles the holder to receive, in preference to common stockholders and the holders of certain other stocks, dividends and a fixed share of the proceeds resulting from a liquidation of the issuer. Preferred stocks may pay fixed or adjustable rates of return, and preferred stock dividends may be cumulative or non-cumulative and participating or non-participating. Cumulative dividend provisions require all or a portion of prior unpaid dividends to be paid before dividends can be paid to the issuer’s common stockholders, while prior unpaid dividends on non-cumulative preferred stock are forfeited. Participating preferred stock may be entitled to a dividend exceeding the issuer’s declared dividend in certain cases, while non-participating preferred stock is entitled only to the stipulated dividend. Preferred stock is subject to issuer-specific and market risks applicable generally to equity securities. As with debt securities, the prices and yields of preferred stocks often move with changes in interest rates and the issuer’s credit quality. Additionally, a company’s preferred stock typically pays

The Income Fund of America — Page 6

dividends only after the company makes required payments to holders of its bonds and other debt. Accordingly, the price of preferred stock will usually react more strongly than bonds and other debt to actual or perceived changes in the issuing company’s financial condition or prospects. Preferred stock of smaller companies may be more vulnerable to adverse developments than preferred stock of larger companies.

Convertible securities — A convertible security is a debt obligation, preferred stock or other security that may be converted, within a specified period of time and at a stated conversion rate, into common stock or other equity securities of the same or a different issuer. The conversion may occur automatically upon the occurrence of a predetermined event or at the option of either the issuer or the security holder. Under certain circumstances, a convertible security may also be called for redemption or conversion by the issuer after a particular date and at predetermined price specified upon issue. If a convertible security held by the fund is called for redemption or conversion, the fund could be required to tender the security for redemption, convert it into the underlying common stock, or sell it to a third party.

The holder of a convertible security is generally entitled to participate in the capital appreciation resulting from a market price increase in the issuer’s common stock and to receive interest paid or accrued until the convertible security matures or is redeemed, converted or exchanged. Before conversion, convertible securities have characteristics similar to non-convertible debt or preferred securities, as applicable. Convertible securities rank senior to common stock in an issuer’s capital structure and, therefore, normally entail less risk than the issuer’s common stock. However, convertible securities may also be subordinate to any senior debt obligations of the issuer, and, therefore, an issuer’s convertible securities may entail more risk than such senior debt obligations. Convertible securities usually offer lower interest or dividend yields than non-convertible debt securities of similar credit quality because of the potential for capital appreciation. In addition, convertible securities are often lower-rated securities.

Because of the conversion feature, the price of a convertible security will normally fluctuate in some proportion to changes in the price of the underlying asset, and, accordingly, convertible securities are subject to risks relating to the activities of the issuer and/or general market and economic conditions. The income component of a convertible security may cushion the security against declines in the price of the underlying asset but may also cause the price of the security to fluctuate based upon changes in interest rates and the credit quality of the issuer. As with a straight fixed income security, the price of a convertible security tends to increase when interest rates decline and decrease when interest rates rise. Like the price of a common stock, the price of a convertible security also tends to increase as the price of the underlying stock rises and to decrease as the price of the underlying stock declines.

Hybrid securities — A hybrid security is a type of security that also has equity and debt characteristics. Like equities, which have no final maturity, a hybrid security may be perpetual. On the other hand, like debt securities, a hybrid security may be callable at the option of the issuer on a date specified at issue. Additionally, like common equities, which may stop paying dividends at virtually any time without violating any contractual terms or conditions, hybrids typically allow for issuers to withhold payment of interest until a later date or to suspend coupon payments entirely without triggering an event of default. Hybrid securities are normally at the bottom of an issuer’s debt capital structure because holders of an issuer’s hybrid securities are structurally subordinated to the issuer’s senior creditors. In bankruptcy, hybrid security holders should only get paid after all senior creditors of the issuer have been paid but before any disbursements are made to the issuer’s equity holders. Accordingly, hybrid securities may be more sensitive to economic changes than more senior debt securities. Such securities may also be viewed as more equity-like by the market when the issuer or its parent company experiences financial difficulties.

The Income Fund of America — Page 7

Contingent convertible securities, which are also known as contingent capital securities, are a form of hybrid security that are intended to either convert into equity or have their principal written down upon the occurrence of certain trigger events. One type of contingent convertible security has characteristics designed to absorb losses, by providing that the liquidation value of the security may be adjusted downward to below the original par value or written off entirely under certain circumstances. For instance, if losses have eroded the issuer’s capital level below a specified threshold, the liquidation value of the security may be reduced in whole or in part. The write-down of the security’s par value may occur automatically and would not entitle holders to institute bankruptcy proceedings against the issuer. In addition, an automatic write-down could result in a reduced income rate if the dividend or interest payment associated with the security is based on the security’s par value. Such securities may, but are not required to, provide for circumstances under which the liquidation value of the security may be adjusted back up to par, such as an improvement in capitalization or earnings. Another type of contingent convertible security provides for mandatory conversion of the security into common shares of the issuer under certain circumstances. The mandatory conversion might relate, for example, to the issuer’s failure to maintain a capital minimum. Since the common stock of the issuer may not pay a dividend, investors in such instruments could experience reduced yields (or no yields at all) and conversion would deepen the subordination of the investor, effectively worsening the investor’s standing in the case of the issuer’s insolvency. An automatic write-down or conversion event with respect to a contingent convertible security will typically be triggered by a reduction in the issuer’s capital level, but may also be triggered by regulatory actions, such as a change in regulatory capital requirements, or by other factors.

Investing outside the United States — Securities of issuers domiciled outside the United States or with significant operations or revenues outside the United States, and securities tied economically to countries outside the United States, may lose value because of adverse political, social, economic or market developments (including social instability, regional conflicts, terrorism and war) in the countries or regions in which the issuers are domiciled, operate or generate revenue or to which the securities are tied economically. These issuers may also be more susceptible to actions of foreign governments such as the imposition of price controls, sanctions, or punitive taxes that could adversely impact the value of these securities. To the extent the fund invests in securities that are denominated in currencies other than the U.S. dollar, these securities may also lose value due to changes in foreign currency exchange rates against the U.S. dollar and/or currencies of other countries. Securities markets in certain countries may be more volatile or less liquid than those in the United States. Investments outside the United States may also be subject to different accounting practices and different regulatory, legal, auditing, financial reporting and recordkeeping standards and practices, and may be more difficult to value, than those in the United States. In addition, the value of investments outside the United States may be reduced by foreign taxes, including foreign withholding taxes on interest and dividends. Further, there may be increased risks of delayed settlement of securities purchased or sold by the fund, which could impact the liquidity of the fund’s portfolio. The risks of investing outside the United States may be heightened in connection with investments in emerging markets.

Additional costs could be incurred in connection with the fund’s investment activities outside the United States. Brokerage commissions may be higher outside the United States, and the fund will bear certain expenses in connection with its currency transactions. Furthermore, increased custodian costs may be associated with maintaining assets in certain jurisdictions.

Investing in emerging markets — Investing in emerging markets may involve risks in addition to and greater than those generally associated with investing in the securities markets of developed countries. For instance, emerging market countries tend to have less developed political, economic and legal systems than those in developed countries. Accordingly, the governments of these countries may be less stable and more likely to intervene in the market economy, for example, by imposing capital controls, nationalizing a company or industry, placing restrictions on foreign ownership and on withdrawing sale proceeds of securities from the country, and/or imposing punitive taxes that could

The Income Fund of America — Page 8

adversely affect the prices of securities. Information regarding issuers in emerging markets may be limited, incomplete or inaccurate, and such issuers may not be subject to regulatory, accounting, auditing, and financial reporting and recordkeeping standards comparable to those to which issuers in more developed markets are subject. The fund’s rights with respect to its investments in emerging markets, if any, will generally be governed by local law, which may make it difficult or impossible for the fund to pursue legal remedies or to obtain and enforce judgments in local courts. In addition, the economies of these countries may be dependent on relatively few industries, may have limited access to capital and may be more susceptible to changes in local and global trade conditions and downturns in the world economy. Securities markets in these countries can also be relatively small and have substantially lower trading volumes. As a result, securities issued in these countries may be more volatile and less liquid, more vulnerable to market manipulation, and more difficult to value, than securities issued in countries with more developed economies and/or markets. Less certainty with respect to security valuations may lead to additional challenges and risks in calculating the fund’s net asset value. Additionally, emerging markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by banks, agents and depositories that are less established than those in developed countries.

In countries where direct foreign investment is limited or prohibited, the fund may invest in operating companies based in such countries through an offshore intermediary entity that, based on contractual agreements, seeks to replicate the rights and obligations of direct equity ownership in such operating company. Because the contractual arrangements do not in fact bestow the fund with actual equity ownership in the operating company, these investment structures may limit the fund’s rights as an investor and create significant additional risks. For example, local government authorities may determine that such structures do not comply with applicable laws and regulations, including those relating to restrictions on foreign ownership. In such event, the intermediary entity and/or the operating company may be subject to penalties, revocation of business and operating licenses or forfeiture of foreign ownership interests, and the fund’s economic interests in the underlying operating company and its rights as an investor may not be recognized, resulting in a loss to the fund and its shareholders. In addition, exerting control through contractual arrangements may be less effective than direct equity ownership, and a company may incur substantial costs to enforce the terms of such arrangements, including those relating to the distribution of the funds among the entities. These special investment structures may also be disregarded for tax purposes by local tax authorities, resulting in increased tax liabilities, and the fund’s control over – and distributions due from – such structures may be jeopardized if the individuals who hold the equity interest in such structures breach the terms of the agreements. While these structures may be widely used to circumvent limits on foreign ownership in certain jurisdictions, there is no assurance that they will be upheld by local regulatory authorities or that disputes regarding the same will be resolved consistently.

Although there is no universally accepted definition, the investment adviser generally considers an emerging market to be a market that is in the earlier stages of its industrialization cycle with a low per capita gross domestic product (“GDP”) and a low market capitalization to GDP ratio relative to those in the United States and the European Union, and would include markets commonly referred to as “frontier markets.” For example, the investment adviser currently expects that most countries not designated as developed markets by MSCI Inc. (“MSCI”) will be treated as emerging markets for equity securities, and that most countries designated as emerging markets by J.P. Morgan or, if not available, Bloomberg will be treated as emerging markets for debt securities.

Certain risk factors related to emerging markets

Currency fluctuations — Certain emerging markets’ currencies have experienced and in the future may experience significant declines against the U.S. dollar. For example, if the U.S. dollar appreciates against foreign currencies, the value of the fund’s emerging markets securities holdings would generally depreciate and vice versa. Further, the fund may lose money due to losses and other expenses incurred in converting various currencies to purchase

The Income Fund of America — Page 9

and sell securities valued in currencies other than the U.S. dollar, as well as from currency restrictions, exchange control regulation, governmental restrictions that limit or otherwise delay the fund's ability to convert or repatriate currencies and currency devaluations.

Government regulation — Certain emerging markets lack uniform accounting, auditing and financial reporting and disclosure standards, have less governmental supervision of financial markets than in the United States, and may not honor legal rights or protections enjoyed by investors in the United States. Certain governments may be more unstable and present greater risks of nationalization or restrictions on foreign ownership of local companies. Repatriation of investment income, capital and the proceeds of sales by foreign investors may require governmental registration and/or approval in some emerging markets. While the fund will only invest in markets where these restrictions are considered acceptable by the investment adviser, a country could impose new or additional repatriation restrictions after the fund’s investment. If this happened, the fund’s response might include, among other things, applying to the appropriate authorities for a waiver of the restrictions or engaging in transactions in other markets designed to offset the risks of decline in that country. Such restrictions will be considered in relation to the fund’s liquidity needs and other factors. Further, some attractive equity securities may not be available to the fund if foreign shareholders already hold the maximum amount legally permissible.

While government involvement in the private sector varies in degree among emerging markets, such involvement may in some cases include government ownership of companies in certain sectors, wage and price controls or imposition of trade barriers and other protectionist measures. With respect to any emerging market, there is no guarantee that some future economic or political crisis will not lead to price controls, forced mergers of companies, expropriation, or creation of government monopolies to the possible detriment of the fund’s investments.

Fluctuations in inflation rates — Rapid fluctuations in inflation rates may have negative impacts on the economies and securities markets of certain emerging market countries.

Less developed securities markets — Emerging markets may be less well-developed and regulated than other markets. These markets have lower trading volumes than the securities markets of more developed countries and may be unable to respond effectively to increases in trading volume. Consequently, these markets may be substantially less liquid than those of more developed countries, and the securities of issuers located in these markets may have limited marketability. These factors may make prompt liquidation of substantial portfolio holdings difficult or impossible at times.

Settlement risks — Settlement systems in emerging markets are generally less well organized than those of developed markets. Supervisory authorities may also be unable to apply standards comparable to those in developed markets. Thus, there may be risks that settlement may be delayed and that cash or securities belonging to the fund may be in jeopardy because of failures of or defects in the systems. In particular, market practice may require that payment be made before receipt of the security being purchased or that delivery of a security be made before payment is received. In such cases, default by a broker or bank (the “counterparty”) through which the transaction is effected might cause the fund to suffer a loss. The fund will seek, where possible, to use counterparties whose financial status is such that this risk is reduced. However, there can be no certainty that the fund will be successful in eliminating this risk, particularly as counterparties operating in emerging markets frequently lack the standing or financial resources of those in developed countries. There may also be a danger that, because of uncertainties in the operation of settlement systems in individual markets, competing claims may arise with respect to securities held by or to be transferred to the fund.

The Income Fund of America — Page 10

Limited market information — The fund may encounter problems assessing investment opportunities in certain emerging markets in light of limitations on available information and different accounting, auditing and financial reporting standards. For example, due to jurisdictional limitations, the Public Company Accounting Oversight Board (“PCAOB”), which regulates auditors of U.S. reporting companies, may be unable to inspect the audit work and practices of PCAOB-registered auditing firms in certain emerging markets. As a result, there is greater risk that financial records and information relating to an issuer’s operations in emerging markets will be incomplete or misleading, which may negatively impact the fund’s investments in such company. When faced with limited market information, the fund’s investment adviser will seek alternative sources of information, and to the extent the investment adviser is not satisfied with the sufficiency or accuracy of the information obtained with respect to a particular market or security, the fund will not invest in such market or security.

Taxation — Taxation of dividends, interest and capital gains received by the fund varies among emerging markets and, in some cases, is comparatively high. In addition, emerging markets typically have less well-defined tax laws and procedures and such laws may permit retroactive taxation so that the fund could become subject in the future to local tax liability that it had not reasonably anticipated in conducting its investment activities or valuing its assets.

Fraudulent securities — Securities purchased by the fund may subsequently be found to be fraudulent or counterfeit, resulting in a loss to the fund.

Remedies — Emerging markets may offer less protection to investors than U.S. markets and, in the event of investor harm, there may be substantially less recourse available to the fund and its shareholders. In addition, as a matter of law or practicality, the fund and its shareholders - as well as U.S. regulators - may encounter substantial difficulties in obtaining and enforcing judgments and other actions against non-U.S. individuals and companies.

Synthetic local access instruments — Participation notes, market access warrants and other similar structured investment vehicles (collectively, “synthetic local access instruments”) are instruments used by investors to obtain exposure to equity investments in local markets where direct ownership by foreign investors is not permitted or is otherwise restricted by local law. Synthetic local access instruments, which are generally structured and sold over-the-counter by a local branch of a bank or broker-dealer that is permitted to purchase equity securities in the local market, are designed to replicate exposure to one or more underlying equity securities. The price and performance of a synthetic local access instrument are normally intended to track the price and performance of the underlying equity assets as closely as possible. However, there can be no assurance that the results of synthetic local access instruments will replicate exactly the performance of the underlying securities due to transaction costs, taxes and other fees and expenses. The holder of a synthetic local access instrument may also be entitled to receive any dividends paid in connection with the underlying equity assets, but usually does not receive voting rights as it would if such holder directly owned the underlying assets.

Investments in synthetic local access instruments involve the same risks associated with a direct investment in the shares of the companies the instruments seek to replicate, including, in particular, the risks associated with investing outside the United States. Synthetic local access instruments also involve risks that are in addition to the risks normally associated with a direct investment in the underlying equity securities. For instance, synthetic local access instruments represent unsecured, unsubordinated contractual obligations of the banks or broker-dealers that issue them. Consequently, a purchaser of a synthetic local access instrument relies on the creditworthiness of such a bank or broker-dealer counterparty and has no rights under the instrument against the issuer of the underlying equity securities. Additionally, there is no guarantee that a liquid market for a synthetic local access

The Income Fund of America — Page 11

instrument will exist or that the issuer of the instrument will be willing to repurchase the instrument when an investor wishes to sell it.

Depositary receipts — Depositary receipts are securities that evidence ownership interests in, and represent the right to receive, a security or a pool of securities that have been deposited with a bank or trust depository. The fund may invest in American Depositary Receipts (“ADRs”), European Depositary Receipts (“EDRs”), Global Depositary Receipts (“GDRs”), and other similar securities. For ADRs, the depository is typically a U.S. financial institution and the underlying securities are issued by a non-U.S. entity. For other depositary receipts, the depository may be a non-U.S. or a U.S. entity, and the underlying securities may be issued by a non-U.S. or a U.S. entity. Depositary receipts will not necessarily be denominated in the same currency as their underlying securities. Generally, ADRs are issued in registered form, denominated in U.S. dollars, and designed for use in the U.S. securities markets. Other depositary receipts, such as EDRs and GDRs, may be issued in bearer form, may be denominated in either U.S. dollars or in non-U.S. currencies, and are primarily designed for use in securities markets outside the United States. ADRs, EDRs and GDRs can be sponsored by the issuing bank or trust company or the issuer of the underlying securities. Although the issuing bank or trust company may impose charges for the collection of dividends and the conversion of such securities into the underlying securities, generally no fees are imposed on the purchase or sale of these securities other than transaction fees ordinarily involved with trading stock. Such securities may be less liquid or may trade at a lower price than the underlying securities of the issuer. Additionally, the issuers of securities underlying depositary receipts may not be obligated to timely disclose information that is considered material under the securities laws of the United States. Therefore, less information may be available regarding these issuers than about the issuers of other securities and there may not be a correlation between such information and the market value of the depositary receipts.

Currency transactions — The fund may enter into currency transactions on a spot (i.e., cash) basis at the prevailing rate in the currency exchange market to provide for the purchase or sale of a currency needed to purchase a security denominated in such currency. In addition, the fund may enter into forward currency contracts and may purchase and sell options on currencies to protect against changes in currency exchange rates, to increase exposure to a particular foreign currency, to shift exposure to currency fluctuations from one currency to another or to seek to increase returns. A forward currency contract is an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract agreed upon by the parties, at a price set at the time of the contract. Some forward currency contracts, called non-deliverable forwards or NDFs, do not call for physical delivery of the currency and are instead settled through cash payments. Forward currency contracts are typically privately negotiated and traded in the interbank market between large commercial banks (or other currency traders) and their customers. Although forward contracts entered into by the fund will typically involve the purchase or sale of a currency against the U.S. dollar, the fund also may purchase or sell a non-U.S. currency against another non-U.S. currency.

The fund may also purchase or write put and call options on foreign currencies on exchanges or in the over-the-counter (“OTC”) market. A put option on a foreign currency gives the purchaser of the option the right to sell a foreign currency at the exercise price until the option expires. A call option on a foreign currency gives the purchaser of the option the right to purchase the currency at the exercise price until the option expires. Currency options, to the extent not exercised, will expire and the fund, as the purchaser, would experience a loss to the extent of the premium paid for the option. Instead of purchasing a call option to hedge against an anticipated increase in the dollar cost of securities to be acquired, the fund could write a put option on the relevant currency, which, if exchange rates move in the manner projected, will expire unexercised and allow the fund to hedge such increased cost up to the amount of the premium. As in the case of other types of options, however, writing a currency option will provide a hedge only up to the amount of the premium, and only if exchange rates move in the expected direction. If this does not occur, the option may be exercised and the fund would be required to purchase or sell the underlying currency at a loss that may not be offset by the amount of the premium. Through the writing of options on foreign currencies, the fund also may be required to

The Income Fund of America — Page 12

forego all or a portion of the benefit that might otherwise have been obtained from favorable movements in exchange rates. OTC options are bilateral contracts that are individually negotiated and they are generally less liquid than exchange-traded options. Although this type of arrangement allows the purchaser or writer greater flexibility to tailor an option to its needs, OTC options generally involve credit risk to the counterparty, whereas for exchange-traded options, credit risk is mutualized through the involvement of the applicable clearing house. Currency options traded on exchanges may be subject to position limits, which may limit the ability of the fund to reduce currency risk using such options. To the extent that the U.S. options markets are closed while the markets for the underlying currencies remain open, substantial price and rate movements may take place in the currency markets that cannot be reflected in the U.S. options markets. See also “Options” for a general description of investment techniques and risks relating to options.

Currency exchange rates generally are determined by forces of supply and demand in the foreign exchange markets and the relative merits of investment in different countries as viewed from an international perspective. Currency exchange rates, as well as foreign currency transactions, can also be affected unpredictably by intervention by U.S. or foreign governments or central banks or by currency controls or political developments in the United States or abroad. Such intervention or other events could prevent the fund from entering into foreign currency transactions, force the fund to exit such transactions at an unfavorable time or price or result in penalties to the fund, any of which may result in losses to the fund.

Generally, the fund will not attempt to protect against all potential changes in exchange rates and the use of forward contracts does not eliminate the risk of fluctuations in the prices of the underlying securities. If the value of the underlying securities declines or the amount of the fund’s commitment increases because of changes in exchange rates, the fund may need to provide additional cash or securities to satisfy its commitment under the forward contract. The fund is also subject to the risk that it may be delayed or prevented from obtaining payments owed to it under the forward contract as a result of the insolvency or bankruptcy of the counterparty with which it entered into the forward contract or the failure of the counterparty to comply with the terms of the contract.

The realization of gains or losses on foreign currency transactions will usually be a function of the investment adviser’s ability to accurately estimate currency market movements. Entering into forward currency transactions may change the fund’s exposure to currency exchange rates and could result in losses to the fund if currencies do not perform as expected by the fund’s investment adviser. For example, if the fund’s investment adviser increases the fund’s exposure to a foreign currency using forward contracts and that foreign currency’s value declines, the fund may incur a loss. In addition, while entering into forward currency transactions could minimize the risk of loss due to a decline in the value of the hedged currency, it could also limit any potential gain that may result from an increase in the value of the currency. See also the “Derivatives” section under "Description of certain securities, investment techniques and risks" for a general description of investment techniques and risks relating to derivatives, including certain currency forwards and currency options.

Forward currency contracts may give rise to leverage, or exposure to potential gains and losses in excess of the initial amount invested. Leverage magnifies gains and losses and could cause the fund to be subject to more volatility than if it had not been leveraged, thereby resulting in a heightened risk of loss. Forward currency contracts are considered derivatives. Accordingly, under the SEC’s rule applicable to the fund’s use of derivatives, a fund’s obligations with respect to these instruments will depend on the fund’s aggregate usage of and exposure to derivatives, and the fund’s usage of forward currency contracts is subject to written policies and procedures reasonably designed to manage the fund’s derivatives risk.

Forward currency transactions also may affect the character and timing of income, gain, or loss recognized by the fund for U.S. tax purposes. The use of forward currency contracts could result in the

The Income Fund of America — Page 13

application of the mark-to-market provisions of the Internal Revenue Code of 1986 as amended (the "Code") and may cause an increase (or decrease) in the amount of taxable dividends paid by the fund.

Indirect exposure to cryptocurrencies – Cryptocurrencies are currencies which exist in a digital form and may act as a store of wealth, a medium of exchange or an investment asset. There are thousands of cryptocurrencies, such as bitcoin. Although the fund has no current intention of directly investing in cryptocurrencies, some issuers have begun to accept cryptocurrency for payment of services, use cryptocurrencies as reserve assets or invest in cryptocurrencies, and the fund may invest in securities of such issuers. The fund may also invest in securities of issuers which provide cryptocurrency-related services.

Cryptocurrencies are subject to fluctuations in value. Cryptocurrencies are not backed by any government, corporation or other identified body. Rather, the value of a cryptocurrency is determined by other factors, such as the perceived future prospects or the supply and demand for such cryptocurrency in the global market for the trading of cryptocurrency. Such trading markets are unregulated and may be more exposed to operational or technical issues as well as fraud or manipulation in comparison to established, regulated exchanges for securities, derivatives and traditional currencies. The value of a cryptocurrency may decline precipitously (including to zero) for a variety of reasons, including, but not limited to, regulatory changes, a loss of confidence in its network or a change in user preference to other cryptocurrencies. An issuer that owns cryptocurrencies may experience custody issues, and may lose its cryptocurrency holdings through theft, hacking, or technical glitches in the applicable blockchain. The fund may experience losses as a result of the decline in value of its securities of issuers that own cryptocurrencies or which provide cryptocurrency-related services. If an issuer that owns cryptocurrencies intends to pay a dividend using such holdings or to otherwise make a distribution of such holdings to its stockholders, such dividends or distributions may face regulatory, operational and technical issues.

Factors affecting the further development of cryptocurrency include, but are not limited to: continued worldwide growth of, or possible cessation of or reversal in, the adoption and use of cryptocurrencies and other digital assets; the developing regulatory environment relating to cryptocurrencies, including the characterization of cryptocurrencies as currencies, commodities, or securities, the tax treatment of cryptocurrencies, and government and quasi-government regulation or restrictions on, or regulation of access to and operation of, cryptocurrency networks and the exchanges on which cryptocurrencies trade, including anti-money laundering regulations and requirements; perceptions regarding the environmental impact of a cryptocurrency; changes in consumer demographics and public preferences; general economic conditions; maintenance and development of open-source software protocols; the availability and popularity of other forms or methods of buying and selling goods and services; the use of the networks supporting digital assets, such as those for developing smart contracts and distributed applications; and general risks tied to the use of information technologies, including cyber risks. A hack or failure of one cryptocurrency may lead to a loss in confidence in, and thus decreased usage and/or value of, other cryptocurrencies.

Derivatives — In pursuing its investment objective(s), the fund may invest in derivative instruments. A derivative is a financial instrument, the value of which depends on, or is otherwise derived from, another underlying variable. Most often, the variable underlying a derivative is the price of a traded asset, such as a traditional cash security (e.g., a stock or bond), a currency or a commodity; however, the value of a derivative can be dependent on almost any variable, from the level of an index or a specified rate to the occurrence (or non-occurrence) of a credit event with respect to a specified reference asset. In addition to investing in forward currency contracts and currency options, as described under “Currency transactions,” the fund may take positions in futures contracts and options on futures contracts and swaps, each of which is a derivative instrument described in greater detail below.

The Income Fund of America — Page 14

Derivative instruments may be distinguished by the manner in which they trade: some are standardized instruments that trade on an organized exchange while others are individually negotiated and traded in the over-the-counter (“OTC”) market. Derivatives also range broadly in complexity, from simple derivatives to more complex instruments. As a general matter, however, all derivatives — regardless of the manner in which they trade or their relative complexities — entail certain risks, some of which are different from, and potentially greater than, the risks associated with investing directly in traditional cash securities.

As is the case with traditional cash securities, derivative instruments are generally subject to counterparty credit risk; however, in some cases, derivatives may pose counterparty risks greater than those posed by cash securities. The use of derivatives involves the risk that a loss may be sustained by the fund as a result of the failure of the fund’s counterparty to make required payments or otherwise to comply with its contractual obligations. For some derivatives, though, the value of — and, in effect, the return on — the instrument may be dependent on both the individual credit of the fund’s counterparty and on the credit of one or more issuers of any underlying assets. If the fund does not correctly evaluate the creditworthiness of its counterparty and, where applicable, of issuers of any underlying reference assets, the fund’s investment in a derivative instrument may result in losses. Further, if a fund’s counterparty were to default on its obligations, the fund’s contractual remedies against such counterparty may be subject to applicable bankruptcy and insolvency laws, which could affect the fund’s rights as a creditor and delay or impede the fund’s ability to receive the net amount of payments that it is contractually entitled to receive. Derivative instruments are subject to additional risks, including operational risk (such as documentation issues, settlement issues and systems failures) and legal risk (such as insufficient documentation, insufficient capacity or authority of a counterparty, and issues with the legality or enforceability of a contract).

The value of some derivative instruments in which the fund invests may be particularly sensitive to changes in prevailing interest rates, currency exchange rates or other market conditions. Like the fund’s other investments, the ability of the fund to successfully utilize such derivative instruments may depend in part upon the ability of the fund’s investment adviser to accurately forecast interest rates and other economic factors. The success of the fund’s derivative investment strategy will also depend on the investment adviser’s ability to assess and predict the impact of market or economic developments on the derivative instruments in which the fund invests, in some cases without having had the benefit of observing the performance of a derivative under all possible market conditions. If the investment adviser incorrectly forecasts such factors and has taken positions in derivative instruments contrary to prevailing market trends, or if the investment adviser incorrectly predicts the impact of developments on a derivative instrument, the fund could suffer losses.

Certain derivatives may also be subject to liquidity and valuation risks. The potential lack of a liquid secondary market for a derivative (and, particularly, for an OTC derivative, including swaps and OTC options) may cause difficulty in valuing or selling the instrument. If a derivative transaction is particularly large or if the relevant market is illiquid, as is often the case with many privately-negotiated OTC derivatives, the fund may not be able to initiate a transaction or to liquidate a position at an advantageous time or price. Particularly when there is no liquid secondary market for the fund’s derivative positions, the fund may encounter difficulty in valuing such illiquid positions. The value of a derivative instrument does not always correlate perfectly with its underlying asset, rate or index, and many derivatives, and OTC derivatives in particular, are complex and often valued subjectively. Improper valuations can result in increased cash payment requirements to counterparties or a loss of value to the fund.

Because certain derivative instruments may obligate the fund to make one or more potential future payments, which could significantly exceed the value of the fund’s initial investments in such instruments, derivative instruments may also have a leveraging effect on the fund’s portfolio. Certain derivatives have the potential for unlimited loss, irrespective of the size of the fund’s investment in the

The Income Fund of America — Page 15

instrument. When a fund leverages its portfolio, investments in that fund will tend to be more volatile, resulting in larger gains or losses in response to market changes.

The fund’s compliance with the SEC’s rule applicable to the fund’s use of derivatives may limit the ability of the fund to use derivatives as part of its investment strategy. The rule requires that a fund that uses derivatives in more than a limited manner, which is currently the case for the fund, adopt a derivatives risk management program, appoint a derivatives risk manager and comply with an outer limit on leverage based on value at risk, or “VaR”. VaR is an estimate of an instrument’s or portfolio’s potential losses over a given time horizon (i.e., 20 trading days) and at a specified confidence level (i.e., 99%). VaR will not provide, and is not intended to provide, an estimate of an instrument’s or portfolio’s maximum potential loss amount. For example, a VaR of 5% with a specified confidence level of 99% would mean that a VaR model estimates that 99% of the time a fund would not be expected to lose more than 5% of its total assets over the given time period. However, 1% of the time, the fund would be expected to lose more than 5% of its total assets, and in such a scenario the VaR model does not provide an estimate of the extent of this potential loss. The derivatives rule may not be effective in limiting the fund’s risk of loss, as measurements of VaR rely on historical data and may not accurately measure the degree of risk reflected in the fund’s derivatives or other investments. A fund is generally required to satisfy the rule’s outer limit on leverage by limiting the fund’s VaR to 200% of the VaR of a designated reference portfolio that does not utilize derivatives each business day. If a fund does not have an appropriate designated reference portfolio in light of the fund’s investments, investment objectives and strategy, a fund must satisfy the rule’s outer limit on leverage by limiting the fund’s VaR to 20% of the value of the fund’s net assets each business day.

Options — The fund may invest in option contracts, including options on futures and options on currencies, as described in more detail under “Futures and Options on Futures” and “Currency Transactions,” respectively. An option contract is a contract that gives the holder of the option, in return for a premium payment, the right to buy from (in the case of a call) or sell to (in the case of a put) the writer of the option the reference instrument underlying the option (or the cash value of the instrument underlying the option) at a specified exercise price. The writer of an option on a security has the obligation, upon exercise of the option, to cash settle or deliver the underlying currency or instrument upon payment of the exercise price (in the case of a call) or to cash settle or take delivery of the underlying currency or instrument and pay the exercise price (in the case of a put).

By purchasing a put option, the fund obtains the right (but not the obligation) to sell the currency or instrument underlying the option (or to deliver the cash value of the instrument underlying the option) at a specified exercise price, which is also referred to as the strike price. In return for this right, the fund pays the current market price, or the option premium, for the option. The fund may terminate its position in a put option by allowing the option to expire or by exercising the option. If the option is allowed to expire, the fund will lose the entire amount of the option premium paid. If the option is exercised, the fund completes the sale of the underlying instrument (or cash settles) at the strike price. The fund may also terminate a put option position by entering into opposing close-out transactions in advance of the option expiration date.

As a buyer of a put option, the fund can expect to realize a gain if the price of the underlying currency or instrument falls substantially. However, if the price of the underlying currency or instrument does not fall enough to offset the cost of purchasing the option, the fund can expect to suffer a loss, albeit a loss limited to the amount of the option premium plus any applicable transaction costs.

The features of call options are essentially the same as those of put options, except that the purchaser of a call option obtains the right (but not the obligation) to purchase, rather than sell, the underlying currency or instrument (or cash settle) at the specified strike price. The

The Income Fund of America — Page 16

buyer of a call option typically attempts to participate in potential price increases of the underlying currency or instrument with risk limited to the cost of the option if the price of the underlying currency or instrument falls. At the same time, the call option buyer can expect to suffer a loss if the price of the underlying currency or instrument does not rise sufficiently to offset the cost of the option.

The writer of a put or call option takes the opposite side of the transaction from the option purchaser. In return for receipt of the option premium, the writer assumes the obligation to pay or receive the strike price for the option’s underlying currency or instrument if the other party to the option chooses to exercise it. The writer may seek to terminate a position in a put option before exercise by entering into opposing close-out transactions in advance of the option expiration date. If the market for the relevant put option is not liquid, however, the writer must be prepared to pay the strike price while the option is outstanding, regardless of price changes.

If the price of the underlying currency or instrument rises, a put writer would generally expect to profit, although its gain would be limited to the amount of the premium it received. If the price of the underlying currency or instrument remains the same over time, it is likely that the writer would also profit because it should be able to close out the option at a lower price. This is because an option’s value decreases with time as the currency or instrument approaches its expiration date. If the price of the underlying currency or instrument falls, the put writer would expect to suffer a loss. This loss should be less than the loss from purchasing the underlying currency or instrument directly, however, because the premium received for writing the option should mitigate the effects of the decline.

Writing a call option obligates the writer to, upon exercise of the option, deliver the option’s underlying currency or instrument in return for the strike price or to make a net cash settlement payment, as applicable. The characteristics of writing call options are similar to those of writing put options, except that writing call options is generally a profitable strategy if prices remain the same or fall. The potential gain for the option seller in such a transaction would be capped at the premium received.

Several risks are associated with transactions in options on currencies, securities and other instruments (referred to as the “underlying instruments”). For example, there may be significant differences between the underlying instruments and options markets that could result in an imperfect correlation between these markets, which could cause a given transaction not to achieve its objectives. When a put or call option on a particular underlying instrument is purchased to hedge against price movements in a related underlying instrument, for example, the price to close out the put or call option may move more or less than the price of the related underlying instrument.

Options prices can diverge from the prices of their underlying instruments for a number of reasons. Options prices are affected by such factors as current and anticipated short-term interest rates, changes in the volatility of the underlying instrument, and the time remaining until expiration of the contract, which may not affect security prices in the same way. Imperfect correlation may also result from differing levels of demand in the options markets and the markets for the underlying instruments, from structural differences in how options and underlying instruments are traded, or from imposition of daily price fluctuation limits or trading halts. The fund may purchase or sell options contracts with a greater or lesser value than the underlying instruments it wishes to hedge or intends to purchase in order to attempt to compensate for differences in volatility between the contract and the underlying instruments, although this may not be successful. If price changes in the fund’s options positions are less correlated with its other investments, the positions may fail to produce anticipated gains or result in losses that are not offset by gains in other investments.

The Income Fund of America — Page 17

There is no assurance that a liquid market will exist for any particular options contract at any particular time. Options may have relatively low trading volumes and liquidity if their strike prices are not close to the current prices of the underlying instruments. In addition, exchanges may establish daily price fluctuation limits for exchange-traded options contracts and may halt trading if a contract’s price moves upward or downward more than the limit in a given day. On volatile trading days when the price fluctuation limit is reached or a trading halt is imposed, it may be impossible to enter into new positions or to close out existing positions. If the market for a contract is not liquid because of price fluctuation limits or otherwise, it could prevent prompt liquidation of unfavorable positions and could potentially require the fund to hold a position until delivery or expiration regardless of changes in its value.

Combined positions involve purchasing and writing options in combination with each other, or in combination with futures or forward contracts, in order to adjust the risk and return profile of the fund’s overall position. For example, purchasing a put option and writing a call option on the same underlying instrument could construct a combined position with risk and return characteristics similar to selling a futures contract (but with leverage embedded). Another possible combined position would involve writing a call option at one strike price and buying a call option at a lower strike price to reduce the risk of the written call option in the event of a substantial price increase. Because such combined options positions involve multiple trades, they result in higher transaction costs and may be more difficult to open and close out.

Futures and options on futures — The fund may enter into futures contracts and options on futures contracts to seek to manage the fund’s interest rate sensitivity by increasing or decreasing the duration of the fund or a portion of the fund’s portfolio. A futures contract is an agreement to buy or sell a security or other financial instrument (the “reference asset”) for a set price on a future date. An option on a futures contract gives the holder of the option the right to buy or sell a position in a futures contract from or to the writer of the option, at a specified price on or before the specified expiration date. Futures contracts and options on futures contracts are standardized, exchange-traded contracts, and, when such contracts are bought or sold, the fund will incur brokerage fees and will be required to maintain margin deposits.

Unlike when the fund purchases or sells a security, such as a stock or bond, no price is paid or received by the fund upon the purchase or sale of a futures contract. When the fund enters into a futures contract, the fund is required to deposit with its futures broker, known as a futures commission merchant (“FCM”), a specified amount of liquid assets in a segregated account in the name of the FCM at the applicable derivatives clearinghouse or exchange. This amount, known as initial margin, is set by the futures exchange on which the contract is traded and may be significantly modified during the term of the contract. The initial margin is in the nature of a performance bond or good faith deposit on the futures contract, which is returned to the fund upon termination of the contract, assuming all contractual obligations have been satisfied. Additionally, on a daily basis, the fund pays or receives cash, or variation margin, equal to the daily change in value of the futures contract. Variation margin does not represent a borrowing or loan by the fund but is instead a settlement between the fund and the FCM of the amount one party would owe the other if the futures contract expired. In computing daily net asset value, the fund will mark-to-market its open futures positions. A fund is also required to deposit and maintain margin with an FCM with respect to put and call options on futures contracts written by the fund. Such margin deposits will vary depending on the nature of the underlying futures contract (and related initial margin requirements), the current market value of the option, and other futures positions held by the fund. In the event of the bankruptcy or insolvency of an FCM that holds margin on behalf of the fund, the fund may be entitled to return of margin owed to it only in proportion to the amount received by the FCM’s other customers, potentially resulting in losses to the fund. An event of bankruptcy or insolvency at a clearinghouse or exchange holding initial margin could also result in losses for the fund.

When the fund invests in futures contracts and options on futures contracts and deposits margin with an FCM, the fund becomes subject to so-called “fellow customer” risk – that is, the risk that one or more customers of the FCM will default on their obligations and that the resulting losses will be so great that the FCM will default on its obligations and margin posted by one customer, such as the fund, will be used to cover a loss caused by a different defaulting customer. Applicable Commodity Futures Trading Commission (“CFTC”) rules generally prohibit the use of one customer’s funds to meet the obligations of another customer and limit the ability of an FCM to use margin posed by non-defaulting customers to satisfy losses caused by defaulting customers. As a general matter, an FCM is required to use its own funds to meet a defaulting customer’s obligations. While a customer’s loss would likely need to be substantial before non-defaulting customers would be exposed to loss on account of fellow customer risk, applicable CFTC rules nevertheless permit the commingling of margin and do not limit the mutualization of customer losses from investment losses, custodial failures, fraud or other causes. If the loss is so great that, notwithstanding the application of an FCM’s own funds, there is a shortfall in the amount of customer funds required to be held in segregation, the FCM could default and be placed into bankruptcy. Under these circumstances, bankruptcy law provides that non-defaulting customers will share pro rata in any shortfall. A shortfall in customer segregated funds may also make the transfer of the accounts of non-defaulting customers to another FCM more difficult.

Although certain futures contracts, by their terms, require actual future delivery of and payment for the reference asset, in practice, most futures contracts are usually closed out before the delivery date by offsetting purchases or sales of matching futures contracts. Closing out an open futures contract purchase or sale is effected by entering into an offsetting futures contract sale or purchase, respectively, for the same aggregate amount of the identical reference asset and the same delivery date. If the offsetting purchase price is less than the original sale price (in each case taking into account transaction costs, including brokerage fees), the fund realizes a gain; if it is more, the fund realizes a loss. Conversely, if the offsetting sale price is more than the original purchase price (in each case taking into account transaction costs, including brokerage fees), the fund realizes a gain; if it is less, the fund realizes a loss.

The fund may purchase and write call and put options on futures. A futures option gives the holder the right, in return for the premium paid, to assume a long position (call) or short position (put) in a futures contract at a specified exercise price at any time during the period of the option. Upon exercise of a call option, the holder acquires a long position in the futures contract, and the writer is assigned the opposite short position. The opposite is true in the case of a put option. A call option is “in the money” if the value of the futures contract that is the subject of the option exceeds the exercise price. A put option is “in the money” if the exercise price exceeds the value of the futures contract that is the subject of the option. See also “Options” above for a general description of investment techniques and risks relating to options.

The value of a futures contract tends to increase and decrease in tandem with the value of its underlying reference asset. Purchasing futures contracts will, therefore, tend to increase the fund’s exposure to positive and negative price fluctuations in the reference asset, much as if the fund had purchased the reference asset directly. When the fund sells a futures contract, by contrast, the value of its futures position will tend to move in a direction contrary to the market for the reference asset. Accordingly, selling futures contracts will tend to offset both positive and negative market price changes, much as if the reference asset had been sold.

There is no assurance that a liquid market will exist for any particular futures or futures options contract at any particular time. Futures exchanges may establish daily price fluctuation limits for futures contracts and may halt trading if a contract’s price moves upward or downward more than the limit in a given day. On volatile trading days, when the price fluctuation limit is

The Income Fund of America — Page 19

reached and a trading halt is imposed, it may be impossible to enter into new positions or close out existing positions. If the market for a futures contract is not liquid because of price fluctuation limits or other market conditions, the fund may be prevented from promptly liquidating unfavorable futures positions and the fund could be required to continue to hold a position until delivery or expiration regardless of changes in its value, potentially subjecting the fund to substantial losses. Additionally, the fund may not be able to take other actions or enter into other transactions to limit or reduce its exposure to the position. Under such circumstances, the fund would remain obligated to meet margin requirements until the position is cleared. As a result, the fund’s access to other assets posted as margin for its futures positions could also be impaired.

Although futures exchanges generally operate similarly in the United States and abroad, foreign futures exchanges may follow trading, settlement and margin procedures that are different than those followed by futures exchanges in the United States. Futures and futures options contracts traded outside the United States may not involve a clearing mechanism or related guarantees and may involve greater risk of loss than U.S.-traded contracts, including potentially greater risk of losses due to insolvency of a futures broker, exchange member, or other party that may owe initial or variation margin to the fund. Margin requirements on foreign futures exchanges may be different than those of futures exchanges in the United States, and, because initial and variation margin payments may be measured in foreign currency, a futures or futures options contract traded outside the United States may also involve the risk of foreign currency fluctuations.

Swaps — The fund may enter into swaps, which are two-party contracts entered into primarily by institutional investors for a specified time period. In a typical swap, two parties agree to exchange the returns earned or realized from one or more underlying assets or rates of return.

Swaps can be traded on a swap execution facility (“SEF”) and cleared through a central clearinghouse (cleared), traded OTC and cleared, or traded bilaterally and not cleared. For example, standardized interest rate swaps and standardized credit default swap indices are traded on SEFs and cleared. Other forms of swaps, such as total return swaps and certain types of interest rate swaps and credit default swap indices are entered into on a bilateral basis. Because clearing interposes a central clearinghouse as the ultimate counterparty to each participant’s swap, and margin is required to be exchanged under the rules of the clearinghouse, central clearing is intended to decrease (but not eliminate) counterparty risk relative to uncleared bilateral swaps. To the extent the fund enters into bilaterally negotiated swaps, the fund will enter into swaps only with counterparties that meet certain credit standards and have agreed to specific collateralization procedures; however, if the counterparty’s creditworthiness deteriorates rapidly and the counterparty defaults on its obligations under the swap or declares bankruptcy, the fund may lose any amount it expected to receive from the counterparty. In addition, bilateral swaps are subject to certain regulatory margin requirements that mandate the posting and collection of minimum margin amounts, which may result in the fund and its counterparties posting higher margin amounts for bilateral swaps than would otherwise be the case.

The term of a swap can be days, months or years and certain swaps may be less liquid than others. If a swap is particularly large or if the relevant market is illiquid, it may not be possible to initiate a transaction or liquidate a position at an advantageous time or price, which may result in significant losses.

Swaps can take different forms. The fund may enter into the following types of swaps:

The Income Fund of America — Page 20

Interest rate swaps — The fund may enter into interest rate swaps to seek to manage the interest rate sensitivity of the fund by increasing or decreasing the duration of the fund or a portion of the fund’s portfolio. An interest rate swap is an agreement between two parties to exchange or swap payments based on changes in an interest rate or rates. Typically, one interest rate is fixed and the other is variable based on a designated short-term interest rate such as the Secured Overnight Financing Rate (“SOFR”), prime rate or other benchmark, or on an inflation index such as the U.S. Consumer Price Index (which is a measure that examines the weighted average of prices of a basket of consumer goods and services and measures changes in the purchasing power of the U.S. dollar and the rate of inflation). In other types of interest rate swaps, known as basis swaps, the parties agree to swap variable interest rates based on different designated short-term interest rates. Interest rate swaps generally do not involve the delivery of securities or other principal amounts. Rather, cash payments are exchanged by the parties based on the application of the designated interest rates to a notional amount, which is the predetermined dollar principal of the trade upon which payment obligations are computed. Accordingly, the fund’s current obligation or right under the swap is generally equal to the net amount to be paid or received under the swap based on the relative value of the position held by each party.

In addition to the risks of entering into swaps discussed above, the use of interest rate swaps involves the risk of losses if interest rates change.

Total return swaps — The fund may enter into total return swaps in order to gain exposure to a market or security without owning or taking physical custody of such security or investing directly in such market. A total return swap is an agreement in which one party agrees to make periodic payments to the other party based on the change in market value of the assets underlying the contract during the specified term in exchange for periodic payments based on a fixed or variable interest rate or the total return from other underlying assets. The asset underlying the contract may be a single security, a basket of securities or a securities index. Like other swaps, the use of total return swaps involves certain risks, including potential losses if a counterparty defaults on its payment obligations to the fund or the underlying assets do not perform as anticipated. There is no guarantee that entering into a total return swap will deliver returns in excess of the interest costs involved and, accordingly, the fund’s performance may be lower than would have been achieved by investing directly in the underlying assets.

Credit default swap indices — In order to assume exposure to a diversified portfolio of credits or to hedge against existing credit risks, the fund may invest in credit default swap indices, including CDX and iTraxx indices (collectively referred to as “CDSIs”). Additionally, in order to assume exposure to the commercial mortgage-backed security sector or to hedge against existing credit and market risks within such sector, the fund may invest in mortgage-backed security credit default swap indices, including the CMBX index (collectively referred to as “CMBXIs”).

A CDSI is based on a portfolio of credit default swaps with similar characteristics, such as credit default swaps on high-yield bonds. A CMBXI is a tradeable index referencing a basket of commercial mortgage-backed securities. In a typical CDSI or CMBXI transaction, one party — the protection buyer — is obligated to pay the other party — the protection seller — a stream of periodic payments over the term of the contract. If a credit event, such as a default or restructuring, occurs with respect to any of the underlying reference obligations, the protection seller must pay the protection buyer the loss on those credits. Also, if a restructuring credit event occurs in an iTraxx index,

The Income Fund of America — Page 21

the fund as protection buyer may receive a single name credit default swap (“CDS”) representing the relevant constituent.

The fund may enter into a CDSI or CMBXI transaction as either protection buyer or protection seller. If the fund is a protection buyer, it would pay the counterparty a periodic stream of payments over the term of the contract and would not recover any of those payments if no credit events were to occur with respect to any of the underlying reference obligations. However, if a credit event did occur, the fund, as a protection buyer, would have the right to deliver the referenced debt obligations or a specified amount of cash, depending on the terms of the applicable agreement, and to receive the par value of such debt obligations from the counterparty protection seller. As a protection seller, the fund would receive fixed payments throughout the term of the contract if no credit events were to occur with respect to any of the underlying reference obligations. If a credit event were to occur, however, the value of any deliverable obligation received by the fund, coupled with the periodic payments previously received by the fund, may be less than the full notional value that the fund, as a protection seller, pays to the counterparty protection buyer, effectively resulting in a loss of value to the fund. Furthermore, as a protection seller, the fund would effectively add leverage to its portfolio because it would have investment exposure to the notional amount of the swap.

The use of CDSI or CMBXI, like all other swaps, is subject to certain risks, including the risk that the fund’s counterparty will default on its obligations. If such a default were to occur, any contractual remedies that the fund might have may be subject to applicable bankruptcy laws, which could delay or limit the fund’s recovery. Thus, if the fund’s counterparty to a CDSI or CMBXI transaction defaults on its obligation to make payments thereunder, the fund may lose such payments altogether or collect only a portion thereof, which collection could involve substantial costs or delays.

Additionally, when the fund invests in a CDSI or CMBXI as a protection seller, the fund will be indirectly exposed to the creditworthiness of issuers of the underlying reference obligations in the index. If the investment adviser to the fund does not correctly evaluate the creditworthiness of issuers of the underlying instruments on which the CDSI or CMBXI is based, the investment could result in losses to the fund.

Obligations backed by the “full faith and credit” of the U.S. government — U.S. government obligations include the following types of securities:

U.S. Treasury securities — U.S. Treasury securities include direct obligations of the U.S. Treasury, such as Treasury bills, notes and bonds. For these securities, the payment of principal and interest is unconditionally guaranteed by the U.S. government, and thus they are of high credit quality.

Federal agency securities — The securities of certain U.S. government agencies and government-sponsored entities are guaranteed as to the timely payment of principal and interest by the full faith and credit of the U.S. government. Such agencies and entities include, but are not limited to, the Federal Financing Bank (“FFB”), the Government National Mortgage Association (“Ginnie Mae”), the U.S. Department of Veterans Affairs (“VA”), the Federal Housing Administration (“FHA”), the Export-Import Bank of the United States (“Exim Bank”), the U.S. International Development Finance Corporation (“DFC”), the Commodity Credit Corporation (“CCC”) and the U.S. Small Business Administration (“SBA”).

The Income Fund of America — Page 22

Such securities are subject to variations in market value due to fluctuations in interest rates and in government policies, among other things, but, if held to maturity, are expected to be paid in full (either at maturity or thereafter). However, from time to time, a high national debt level, and uncertainty regarding negotiations to increase the U.S. government’s debt ceiling and periodic legislation to fund the government, could increase the risk that the U.S. government may default on its obligations and/or lead to a downgrade of the credit rating of the U.S. government. Such an event could adversely affect the value of investments in securities backed by the full faith and credit of the U.S. government, cause the fund to suffer losses and lead to significant disruptions in U.S. and global markets. Regulatory or market changes or conditions could increase demand for U.S. government securities and affect the availability of such instruments for investment and the fund's ability to pursue its investment strategies.

Other federal agency obligations — Additional federal agency securities are neither direct obligations of, nor guaranteed by, the U.S. government. These obligations include securities issued by certain U.S. government agencies and government-sponsored entities. However, they generally involve some form of federal sponsorship: some operate under a congressional charter; some are backed by collateral consisting of “full faith and credit” obligations as described above; some are supported by the issuer’s right to borrow from the Treasury; and others are supported only by the credit of the issuing government agency or entity. These agencies and entities include, but are not limited to: the Federal Home Loan Banks, the Federal Home Loan Mortgage Corporation (“Freddie Mac”), the Federal National Mortgage Association (“Fannie Mae”), the Tennessee Valley Authority and the Federal Farm Credit Bank System.

In 2008, Freddie Mac and Fannie Mae were placed into conservatorship by their new regulator, the Federal Housing Finance Agency (“FHFA”). Simultaneously, the U.S. Treasury made a commitment of indefinite duration to maintain the positive net worth of both firms. As conservator, the FHFA has the authority to repudiate any contract either firm has entered into prior to the FHFA’s appointment as conservator (or receiver should either firm go into default) if the FHFA, in its sole discretion determines that performance of the contract is burdensome and repudiation would promote the orderly administration of Fannie Mae’s or Freddie Mac’s affairs. While the FHFA has indicated that it does not intend to repudiate the guaranty obligations of either entity, doing so could adversely affect holders of their mortgage-backed securities. For example, if a contract were repudiated, the liability for any direct compensatory damages would accrue to the entity’s conservatorship estate and could only be satisfied to the extent the estate had available assets. As a result, if interest payments on Fannie Mae or Freddie Mac mortgage-backed securities held by the fund were reduced because underlying borrowers failed to make payments or such payments were not advanced by a loan servicer, the fund’s only recourse might be against the conservatorship estate, which might not have sufficient assets to offset any shortfalls.

The FHFA, in its capacity as conservator, has the power to transfer or sell any asset or liability of Fannie Mae or Freddie Mac. The FHFA has indicated it has no current intention to do this; however, should it do so a holder of a Fannie Mae or Freddie Mac mortgage-backed security would have to rely on another party for satisfaction of the guaranty obligations and would be exposed to the credit risk of that party.

Certain rights provided to holders of mortgage-backed securities issued by Fannie Mae or Freddie Mac under their operative documents may not be enforceable against the FHFA, or enforcement may be delayed during the course of the conservatorship or any future receivership. For example, the operative documents may provide that upon the occurrence of an event of default by Fannie Mae or Freddie Mac, holders of a requisite percentage of the mortgage-backed security may replace the entity as trustee. However, under the Federal Housing Finance Regulatory Reform Act of 2008, holders may not enforce this right if the event of default arises solely because a conservator or receiver has been appointed.

Pass-through securities — The fund may invest in various debt obligations backed by pools of mortgages, corporate loans or other assets including, but not limited to, residential mortgage loans, home equity loans, mortgages on commercial buildings, consumer loans and equipment leases. Principal and interest payments made on the underlying asset pools backing these obligations are typically passed through to investors, net of any fees paid to any insurer or any guarantor of the securities. Pass-through securities may have either fixed or adjustable coupons. The risks of an investment in these obligations depend in part on the type of the collateral securing the obligations and the class of the instrument in which the fund invests. These securities include:

Mortgage-backed securities — These securities may be issued by U.S. government agencies and government-sponsored entities, such as Ginnie Mae, Fannie Mae and Freddie Mac, and by private entities. The payment of interest and principal on mortgage-backed obligations issued by U.S. government agencies may be guaranteed by the full faith and credit of the U.S. government (in the case of Ginnie Mae), or may be guaranteed by the issuer (in the case of Fannie Mae and Freddie Mac). However, these guarantees do not apply to the market prices and yields of these securities, which vary with changes in interest rates.

Mortgage-backed securities issued by private entities are structured similarly to those issued by U.S. government agencies. However, these securities and the underlying mortgages are not guaranteed by any government agencies and the underlying mortgages are not subject to the same underwriting requirements. These securities generally are structured with one or more types of credit enhancements such as insurance or letters of credit issued by private companies. Borrowers on the underlying mortgages are usually permitted to prepay their underlying mortgages. Prepayments can alter the effective maturity of these instruments. In addition, delinquencies, losses or defaults by borrowers can adversely affect the prices and volatility of these securities. Such delinquencies and losses can be exacerbated by declining or flattening housing and property values. This, along with other outside pressures, such as bankruptcies and financial difficulties experienced by mortgage loan originators, decreased investor demand for mortgage loans and mortgage-related securities and increased investor demand for yield, can adversely affect the value and liquidity of mortgage-backed securities.

Collateralized mortgage obligations (CMOs) — CMOs are also backed by a pool of mortgages or mortgage loans, which are divided into two or more separate bond issues. CMOs issued by U.S. government agencies are backed by agency mortgages, while privately issued CMOs may be backed by either government agency mortgages or private mortgages. Payments of principal and interest are passed through to each bond issue at varying schedules resulting in bonds with different coupons, effective maturities and sensitivities to interest rates. Some CMOs may be structured in a way that when interest rates change, the impact of changing prepayment rates on the effective maturities of certain issues of these securities is magnified. CMOs may be less liquid or may exhibit greater price volatility than other types of mortgage or asset-backed securities.

Commercial mortgage-backed securities — These securities are backed by mortgages on commercial property, such as hotels, office buildings, retail stores, hospitals and other commercial buildings. These securities may have a lower prepayment uncertainty than other mortgage-related securities because commercial mortgage loans generally prohibit or impose penalties on prepayments of principal. In addition, commercial mortgage-related securities often are structured with some form of credit enhancement to protect against potential losses on the underlying mortgage loans. Many of the risks of investing in commercial mortgage-backed securities reflect the risks of investing in the real estate securing the underlying mortgage loans, including the effects of local and other economic conditions on real estate markets, the ability of tenants to make rental payments and the ability of a property to attract and retain tenants. Commercial mortgage-backed securities may be less liquid or exhibit

The Income Fund of America — Page 24

greater price volatility than other types of mortgage or asset-backed securities and may be more difficult to value.

Asset-backed securities — These securities are backed by other assets such as credit card, automobile or consumer loan receivables, retail installment loans or participations in pools of leases. Credit support for these securities may be based on the underlying assets and/or provided through credit enhancements by a third party. The values of these securities are sensitive to changes in the credit quality of the underlying collateral, the credit strength of the credit enhancement, changes in interest rates and at times the financial condition of the issuer. Obligors of the underlying assets also may make prepayments that can change effective maturities of the asset-backed securities. These securities may be less liquid and more difficult to value than other securities.

Collateralized bond obligations (CBOs) and collateralized loan obligations (CLOs) — A CBO is a trust typically backed by a diversified pool of fixed-income securities, which may include high risk, lower rated securities. A CLO is a trust typically collateralized by a pool of loans, which may include, among others, senior secured loans, senior unsecured loans, and subordinate corporate loans, including lower rated loans. CBOs and CLOs may charge management fees and administrative expenses.

For both CBOs and CLOs, the cash flows from the trust are split into two or more portions, called tranches, varying in risk and yield. The riskiest and highest yielding portion is the “equity” tranche which bears the bulk of any default by the bonds or loans in the trust and is constructed to protect the other, more senior tranches from default. Since they are partially protected from defaults, the more senior tranches typically have higher ratings and lower yields than the underlying securities in the trust and can be rated investment grade. Despite the protection from the equity tranche, the more senior tranches can still experience substantial losses due to actual defaults of the underlying assets, increased sensitivity to defaults due to impairment of the collateral or the more junior tranches, market anticipation of defaults, as well as potential general aversions to CBO or CLO securities as a class. Normally, these securities are privately offered and sold, and thus, are not registered under the securities laws. CBOs and CLOs may be less liquid, may exhibit greater price volatility and may be more difficult to value than other securities.

“IOs” and “POs” are issued in portions or tranches with varying maturities and characteristics. Some tranches may only receive the interest paid on the underlying mortgages (IOs) and others may only receive the principal payments (POs). The values of IOs and POs are extremely sensitive to interest rate fluctuations and prepayment rates, and IOs are also subject to the risk of early repayment of the underlying mortgages that will substantially reduce or eliminate interest payments.

Municipal bonds — Municipal bonds are debt obligations that are exempt from federal, state and/or local income taxes. Opinions relating to the validity of municipal bonds, exclusion of municipal bond interest from an investor’s gross income for federal income tax purposes and, where applicable, state and local income tax, are rendered by bond counsel to the issuing authorities at the time of issuance.

The two principal classifications of municipal bonds are general obligation bonds and limited obligation or revenue bonds. General obligation bonds are secured by the issuer’s pledge of its full faith and credit including, if available, its taxing power for the payment of principal and interest. Issuers of general obligation bonds include states, counties, cities, towns and various regional or special districts. The proceeds of these obligations are used to fund a wide range of public facilities, such as the construction or improvement of schools, highways and roads, water and sewer systems and facilities for a variety of other public purposes. Lease revenue bonds or certificates of participation in

The Income Fund of America — Page 25

leases are payable from annual lease rental payments from a state or locality. Annual rental payments are payable to the extent such rental payments are appropriated annually.

Typically, the only security for a limited obligation or revenue bond is the net revenue derived from a particular facility or class of facilities financed thereby or, in some cases, from the proceeds of a special tax or other special revenues. Revenue bonds have been issued to fund a wide variety of revenue-producing public capital projects including: electric, gas, water and sewer systems; highways, bridges and tunnels; port and airport facilities; colleges and universities; hospitals; and convention, recreational, tribal gaming and housing facilities. Although the security behind these bonds varies widely, many provide additional security in the form of a debt service reserve fund which may also be used to make principal and interest payments on the issuer's obligations. In addition, some revenue obligations (as well as general obligations) are insured by a bond insurance company or backed by a letter of credit issued by a banking institution.

Revenue bonds also include, for example, pollution control, health care and housing bonds, which, although nominally issued by municipal authorities, are generally not secured by the taxing power of the municipality but by the revenues of the authority derived from payments by the private entity which owns or operates the facility financed with the proceeds of the bonds. Obligations of housing finance authorities have a wide range of security features, including reserve funds and insured or subsidized mortgages, as well as the net revenues from housing or other public projects. Many of these bonds do not generally constitute the pledge of the credit of the issuer of such bonds. The credit quality of such revenue bonds is usually directly related to the credit standing of the user of the facility being financed or of an institution which provides a guarantee, letter of credit or other credit enhancement for the bond issue.

Equity-linked notes — The fund may purchase equity-linked notes to enhance the current income of its portfolio. Equity-linked notes are hybrid instruments that are specially designed to combine the characteristics of one or more reference securities — usually a single stock, a stock index or a basket of stocks — and a related equity derivative, such as a put or call option, in a single note form. For example, an equity-linked note that refers to the stock of an issuer may be the economic equivalent of holding a position in that stock and simultaneously selling a call option on that stock with a strike price greater than the current stock price. The holder of the note would be exposed to decreases in the price of the equity to the same extent as if it held the equity directly. However, if the stock appreciated in value, the noteholder would only benefit from stock price increases up to the strike price (i.e., the point at which the holder of the call option would be expected to exercise its right to buy the underlying stock). Additionally, the terms of an equity-linked note may provide for periodic interest payments to holders at either a fixed or floating rate.

As described in the example above, the return on an equity-linked note is generally tied to the performance of the underlying reference security or securities. In addition to any interest payments made during the term of the note, at maturity, the noteholder usually receives a return of principal based on the capital appreciation of the linked securities. Depending on the terms of the issuance, the maximum principal amount to be repaid on the equity-linked note may be capped. For example, in consideration for greater current income or yield, a noteholder may forego its participation in the capital appreciation of the underlying equity assets above a predetermined price limit. Alternatively, if the linked securities have depreciated in value, or if their price fluctuates outside of a preset range, the noteholder may receive only the principal amount of the note, or may lose the principal invested in the equity-linked note entirely.

The price of an equity-linked note is derived from the value of the underlying linked securities. The level and type of risk involved in the purchase of an equity-linked note by the fund is similar to the risk involved in the purchase of the underlying linked securities. However, the value of an equity-linked note is also dependent on the individual credit of the issuer of the note, which, in the case of an unsecured note, will generally be a major financial institution, and, in the case of a collateralized note,

The Income Fund of America — Page 26

will generally be a trust or other special purpose vehicle or finance subsidiary established by a major financial institution for the limited purpose of issuing the note. An investment in an equity-linked note bears the risk that the issuer of the note will default or become bankrupt. In such an event, the fund may have difficulty being repaid, or may fail to be repaid, the principal amount of, or income from, its investment. Like other structured products, equity-linked notes are frequently secured by collateral consisting of a combination of debt or related equity securities to which payments under the notes are linked. If so secured, the fund would look to this underlying collateral for satisfaction of claims in the event that the issuer of an equity-linked note defaulted under the terms of the note. However, depending on the law of the jurisdictions in which an issuer is organized and in which the note is issued, in the event of default, the fund may incur substantial expenses in seeking recovery under an equity-linked note, and may have limited legal recourse in attempting to do so.

Equity-linked notes are often privately placed and may not be rated, in which case the fund will be more dependent than would otherwise be the case on the ability of the investment adviser to evaluate the creditworthiness of the issuer, the underlying security, any collateral features of the note, and the potential for loss due to market and other factors. Ratings of issuers of equity-linked notes refer only to the creditworthiness of the issuer and strength of related collateral arrangements or other credit supports, and do not take into account, or attempt to rate, any potential risks of the underlying equity securities. The fund’s successful use of equity-linked notes will usually depend on the investment adviser’s ability to accurately forecast movements in the prices of the underlying securities. Should the prices of the underlying securities move in an unexpected manner, or should the structure of a note respond to market conditions differently than anticipated, the fund may not achieve the anticipated benefits of the investment in the equity-linked note, and the fund may realize losses, which could be significant and could include the fund’s entire principal investment in the note.

Equity-linked notes are generally designed for the over-the-counter institutional investment market, and the secondary market for equity-linked notes may be limited. The lack of a liquid secondary market may have an adverse effect on the ability of the fund to accurately value and/or sell the equity-linked notes in its portfolio.

Real estate investment trusts — Real estate investment trusts ("REITs"), which primarily invest in real estate or real estate-related loans, may issue equity or debt securities. Equity REITs own real estate properties, while mortgage REITs hold construction, development and/or long-term mortgage loans. The values of REITs may be affected by changes in the value of the underlying property of the trusts, the creditworthiness of the issuer, property taxes, interest rates, tax laws and regulatory requirements, such as those relating to the environment. Both types of REITs are dependent upon management skill and the cash flows generated by their holdings, the real estate market in general and the possibility of failing to qualify for any applicable pass-through tax treatment or failing to maintain any applicable exemptive status afforded under relevant laws.

Inflation-linked bonds — The fund may invest in inflation-linked bonds issued by governments, their agencies or instrumentalities and corporations.

The principal amount of an inflation-linked bond is adjusted in response to changes in the level of an inflation index, such as the Consumer Price Index for Urban Consumers (“CPURNSA”). If the index measuring inflation falls, the principal value or coupon of these securities will be adjusted downward. Consequently, the interest payable on these securities will be reduced. Also, if the principal value of these securities is adjusted according to the rate of inflation, the adjusted principal value repaid at maturity may be less than the original principal. In the case of U.S. Treasury Inflation-Protected Securities (“TIPS”), currently the only inflation-linked security that is issued by the U.S. Treasury, the principal amounts are adjusted daily based upon changes in the rate of inflation (as currently represented by the non-seasonally adjusted CPURNSA, calculated with a three-month lag). TIPS may pay interest semi-annually, equal to a fixed percentage of the inflation-adjusted principal amount. The interest rate on these bonds is fixed at issuance, but over the life of the bond this interest may be paid

The Income Fund of America — Page 27

on an increasing or decreasing principal amount that has been adjusted for inflation. The current market value of TIPS is not guaranteed and will fluctuate. However, the U.S. government guarantees that, at maturity, principal will be repaid at the higher of the original face value of the security (in the event of deflation) or the inflation adjusted value.

Other non-U.S. sovereign governments also issue inflation-linked securities that are tied to their own local consumer price indexes and that offer similar deflationary protection. In certain of these non-U.S. jurisdictions, the repayment of the original bond principal upon the maturity of an inflation-linked bond is not guaranteed, allowing for the amount of the bond repaid at maturity to be less than par. Corporations also periodically issue inflation-linked securities tied to CPURNSA or similar inflationary indexes. While TIPS and non-U.S. sovereign inflation-linked securities are currently the largest part of the inflation-linked market, the fund may invest in corporate inflation-linked securities.

The value of inflation-linked securities is expected to change in response to the changes in real interest rates. Real interest rates, in turn, are tied to the relationship between nominal interest rates and the rate of inflation. If inflation were to rise at a faster rate than nominal interest rates, real interest rates would decline, leading to an increase in value of the inflation-linked securities. In contrast, if nominal interest rates were to increase at a faster rate than inflation, real interest rates might rise, leading to a decrease in value of inflation-linked securities. There can be no assurance, however, that the value of inflation-linked securities will be directly correlated to the changes in interest rates. If interest rates rise due to reasons other than inflation, investors in these securities may not be protected to the extent that the increase is not reflected in the security’s inflation measure.

The interest rate for inflation-linked bonds is fixed at issuance as a percentage of this adjustable principal. Accordingly, the actual interest income may both rise and fall as the principal amount of the bonds adjusts in response to movements of the consumer price index. For example, typically interest income would rise during a period of inflation and fall during a period of deflation.

The market for inflation-linked securities may be less developed or liquid, and more volatile, than certain other securities markets. There is a limited number of inflation-linked securities currently available for the fund to purchase, making the market less liquid and more volatile than the U.S. Treasury and agency markets.

Reinsurance related notes and bonds — The fund may invest in reinsurance related notes and bonds. These instruments, which are typically issued by special purpose reinsurance companies, transfer an element of insurance risk to the note or bond holders. For example, such a note or bond could provide that the reinsurance company would not be required to repay all or a portion of the principal value of the note or bond if losses due to a catastrophic event under the policy (such as a major hurricane) exceed certain dollar thresholds. Consequently, the fund may lose the entire amount of its investment in such bonds or notes if such an event occurs and losses exceed certain dollar thresholds. In this instance, investors would have no recourse against the insurance company. These instruments may be issued with fixed or variable interest rates and rated in a variety of credit quality categories by the rating agencies.

Cash and cash equivalents — The fund may hold cash or invest in cash equivalents. Cash equivalents include, but are not limited to: (a) shares of money market or similar funds managed by the investment adviser or its affiliates; (b) shares of other money market funds; (c) commercial paper; (d) short-term bank obligations (for example, certificates of deposit, bankers’ acceptances (time drafts on a commercial bank where the bank accepts an irrevocable obligation to pay at maturity)) or bank notes; (e) savings association and savings bank obligations (for example, bank notes and certificates of deposit issued by savings banks or savings associations); (f) securities of the U.S. government, its agencies or instrumentalities that mature, or that may be redeemed, in one year or less; and (g) higher quality corporate bonds and notes that mature, or that may be redeemed, in one year or less.

The Income Fund of America — Page 28

Commercial paper — The fund may purchase commercial paper. Commercial paper refers to short-term promissory notes issued by a corporation to finance its current operations. Such securities normally have maturities of thirteen months or less and, though commercial paper is often unsecured, commercial paper may be supported by letters of credit, surety bonds or other forms of collateral. Maturing commercial paper issuances are usually repaid by the issuer from the proceeds of new commercial paper issuances. As a result, investment in commercial paper is subject to rollover risk, or the risk that the issuer cannot issue enough new commercial paper to satisfy its outstanding commercial paper. Like all fixed income securities, commercial paper prices are susceptible to fluctuations in interest rates. If interest rates rise, commercial paper prices will decline and vice versa. However, the short-term nature of a commercial paper investment makes it less susceptible to volatility than many other fixed income securities because interest rate risk typically increases as maturity lengths increase. Commercial paper tends to yield smaller returns than longer-term corporate debt because securities with shorter maturities typically have lower effective yields than those with longer maturities. As with all fixed income securities, there is a chance that the issuer will default on its commercial paper obligations and commercial paper may become illiquid or suffer from reduced liquidity in these or other situations.

Commercial paper in which the fund may invest includes commercial paper issued in reliance on the exemption from registration afforded by Section 4(a)(2) of the Securities Act of 1933, as amended (the “1933 Act”). Section 4(a)(2) commercial paper has substantially the same price and liquidity characteristics as commercial paper generally, except that the resale of Section 4(a)(2) commercial paper is limited to institutional investors who agree that they are purchasing the paper for investment purposes and not with a view to public distribution. Technically, such a restriction on resale renders Section 4(a)(2) commercial paper a restricted security under the 1933 Act. In practice, however, Section 4(a)(2) commercial paper typically can be resold as easily as any other unrestricted security held by the fund. Accordingly, Section 4(a)(2) commercial paper has been generally determined to be liquid under procedures adopted by the fund’s board of trustees.

Restricted or illiquid securities — The fund may purchase securities subject to restrictions on resale. Restricted securities may only be sold pursuant to an exemption from registration under the Securities Act of 1933, as amended (the “1933 Act”), or in a registered public offering. Where registration is required, the holder of a registered security may be obligated to pay all or part of the registration expense and a considerable period may elapse between the time it decides to seek registration and the time it may be permitted to sell a security under an effective registration statement. Difficulty in selling such securities may result in a loss to the fund or cause it to incur additional administrative costs.

Some fund holdings (including some restricted securities) may be deemed illiquid if the fund expects that a reasonable portion of the holding cannot be sold in seven calendar days or less without the sale significantly changing the market value of the investment. The determination of whether a holding is considered illiquid is made by the fund’s adviser under a liquidity risk management program adopted by the fund’s board and administered by the fund’s adviser. The fund may incur significant additional costs in disposing of illiquid securities.

Repurchase agreements — The fund may enter into repurchase agreements, or “repos”, under which the fund buys a security and obtains a simultaneous commitment from the seller to repurchase the security at a specified time and price. Because the security purchased constitutes collateral for the repurchase obligation, a repo may be considered a loan by the fund that is collateralized by the security purchased. Repos permit the fund to maintain liquidity and earn income over periods of time as short as overnight.

The seller must maintain with a custodian collateral equal to at least the repurchase price, including accrued interest. In tri-party repos and centrally cleared or “sponsored” repos, a third-party custodian, either a clearing bank in the case of tri-party repos or a central clearing counterparty in the case of

The Income Fund of America — Page 29

centrally cleared repos, facilitates repo clearing and settlement, including by providing collateral management services. In bilateral repos, the parties themselves are responsible for settling transactions.

The fund will only enter into repos involving securities of the type in which it could otherwise invest. If the seller under the repo defaults, the fund may incur a loss if the value of the collateral securing the repo has declined and may incur disposition costs and delays in connection with liquidating the collateral. If bankruptcy proceedings are commenced with respect to the seller, realization of the collateral by the fund may be delayed or limited.

Loan assignments and participations — The fund may invest in loans or other forms of indebtedness that represent interests in amounts owed by corporations or other borrowers (collectively “borrowers”). The investment adviser defines debt securities to include investments in loans, such as loan assignments and participations. Loans may be originated by the borrower in order to address its working capital needs, as a result of a reorganization of the borrower’s assets and liabilities (recapitalizations), to merge with or acquire another company (mergers and acquisitions), to take control of another company (leveraged buy-outs), to provide temporary financing (bridge loans), or for other corporate purposes. Most corporate loans are variable or floating rate obligations.

Some loans may be secured in whole or in part by assets or other collateral. In other cases, loans may be unsecured or may become undersecured by declines in the value of assets or other collateral securing such loan. The greater the value of the assets securing the loan the more the lender is protected against loss in the case of nonpayment of principal or interest. Loans made to highly leveraged borrowers may be especially vulnerable to adverse changes in economic or market conditions and may involve a greater risk of default.

Some loans may represent revolving credit facilities or delayed funding loans, in which a lender agrees to make loans up to a maximum amount upon demand by the borrower during a specified term. These commitments may have the effect of requiring the fund to increase its investment in a company at a time when it might not otherwise decide to do so (including at a time when the company’s financial condition makes it unlikely that such amounts will be repaid).

Some loans may represent debtor-in-possession financings (commonly known as “DIP financings”). DIP financings are arranged when an entity seeks the protections of the bankruptcy court under Chapter 11 of the U.S. Bankruptcy Code. These financings allow the entity to continue its business operations while reorganizing under Chapter 11. Such financings constitute senior liens on unencumbered collateral (i.e., collateral not subject to other creditors’ claims). There is a risk that the entity will not emerge from Chapter 11 and will be forced to liquidate its assets under Chapter 7 of the U.S. Bankruptcy Code. In the event of liquidation, the fund’s only recourse will be against the collateral securing the DIP financing.

The investment adviser generally makes investment decisions based on publicly available information, but may rely on non-public information if necessary. Borrowers may offer to provide lenders with material, non-public information regarding a specific loan or the borrower in general. The investment adviser generally chooses not to receive this information. As a result, the investment adviser may be at a disadvantage compared to other investors that may receive such information. The investment adviser’s decision not to receive material, non-public information may impact the investment adviser’s ability to assess a borrower’s requests for amendments or waivers of provisions in the loan agreement. However, the investment adviser may on a case-by-case basis decide to receive such information when it deems prudent. In these situations the investment adviser may be restricted from trading the loan or buying or selling other debt and equity securities of the borrower while it is in possession of such material, non-public information, even if such loan or other security is declining in value.

The Income Fund of America — Page 30

The fund normally acquires loan obligations through an assignment from another lender, but also may acquire loan obligations by purchasing participation interests from lenders or other holders of the interests. When the fund purchases assignments, it acquires direct contractual rights against the borrower on the loan. The fund acquires the right to receive principal and interest payments directly from the borrower and to enforce its rights as a lender directly against the borrower. However, because assignments are arranged through private negotiations between potential assignees and potential assignors, the rights and obligations acquired by a fund as the purchaser of an assignment may differ from, and be more limited than, those held by the assigning lender. Loan assignments are often administered by a financial institution that acts as agent for the holders of the loan, and the fund may be required to receive approval from the agent and/or borrower prior to the purchase of a loan. Risks may also arise due to the inability of the agent to meet its obligations under the loan agreement.

Loan participations are loans or other direct debt instruments that are interests in amounts owed by the borrower to another party. They may represent amounts owed to lenders or lending syndicates, to suppliers of goods or services, or to other parties. The fund will have the right to receive payments of principal, interest and any fees to which it is entitled only from the lender selling the participation and only upon receipt by the lender of the payments from the borrower. In connection with purchasing participations, the fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement relating to the loan, nor any rights of set-off against the borrower. In addition, the fund may not directly benefit from any collateral supporting the loan in which it has purchased the participation and the fund will have to rely on the agent bank or other financial intermediary to apply appropriate credit remedies. As a result, the fund will be subject to the credit risk of both the borrower and the lender that is selling the participation. In the event of the insolvency of the lender selling a participation, a fund may be treated as a general creditor of the lender and may not benefit from any set-off between the lender and the borrower.

Loan assignments and participations are generally subject to legal or contractual restrictions on resale and are not currently listed on any securities exchange or automatic quotation system. Risks may arise due to delayed settlements of loan assignments and participations. The investment adviser expects that most loan assignments and participations purchased for the fund will trade on a secondary market. However, although secondary markets for investments in loans are growing among institutional investors, a limited number of investors may be interested in a specific loan. It is possible that loan participations, in particular, could be sold only to a limited number of institutional investors. If there is no active secondary market for a particular loan, it may be difficult for the investment adviser to sell the fund’s interest in such loan at a price that is acceptable to it and to obtain pricing information on such loan.

Investments in loan participations and assignments present the possibility that the fund could be held liable as a co-lender under emerging legal theories of lender liability. In addition, if the loan is foreclosed, the fund could be part owner of any collateral and could bear the costs and liabilities of owning and disposing of the collateral. In addition, some loan participations and assignments may not be rated by major rating agencies and may not be protected by securities laws.

Unfunded commitment agreements — The fund may enter into unfunded commitment agreements to make certain investments, including unsettled bank loan purchase transactions. Under the SEC’s rule applicable to the fund’s use of derivatives, unfunded commitment agreements are not derivatives transactions. The fund will only enter into such unfunded commitment agreements if the fund reasonably believes, at the time it enters into such agreement, that it will have sufficient cash and cash equivalents to meet its obligations with respect to all of its unfunded commitment agreements as they come due.

Forward commitment, when issued and delayed delivery transactions — The fund may enter into commitments to purchase or sell securities at a future date. When the fund agrees to purchase such securities, it assumes the risk of any decline in value of the security from the date of the agreement,

The Income Fund of America — Page 31

and when the fund agrees to sell such securities, it assumes the risk of any increase in value of the security. If the other party to such a transaction fails to deliver or pay for the securities, the fund could miss a favorable price or yield opportunity, or could experience a loss.

The fund may roll such transactions in lieu of taking physical delivery of the contract’s underlying assets on the settlement date. When rolling the purchase of these types of transactions, the fund sells mortgage-backed securities for delivery in the current month and simultaneously contracts to repurchase substantially similar (same type, coupon, and maturity) securities on a specified future date, at a pre-determined price. When rolling the sale of these types of transactions, the fund purchases mortgage-backed securities for delivery in the current month and simultaneously contracts to sell substantially similar (same type, coupon, and maturity) securities on a specified future date, at a pre-determined price.

When rolling these types of transactions, during the period between the initial sale (or purchase) and subsequent repurchase (or sale) (the “roll period”), the fund forgoes principal and interest paid on the mortgage-backed securities. The fund is compensated by the price differential between the original and new contracts (often referred to as the “drop”), if any, as well as by the interest earned on the cash proceeds of any sales. The fund also takes the risk that market prices or characteristics of the underlying mortgage-backed securities may move unfavorably between the original and new contracts. The fund could suffer a loss if the contracting party fails to perform the future transaction and the fund is therefore unable to buy or sell back the mortgage-backed securities it initially either sold or purchased, respectively. These transactions are accounted for as purchase and sale transactions, which contribute to the fund’s portfolio turnover rate.

With TBA transactions, the particular securities (i.e., specified mortgage pools) to be delivered or received are not identified at the trade date, but are “to be announced” at a later settlement date. However, securities to be delivered must meet specified criteria, including face value, coupon rate and maturity, and be within industry-accepted “good delivery” standards. The fund will not use these transactions for the purpose of leveraging. Although these transactions will not be entered into for leveraging purposes, the fund temporarily could be in a leveraged position (because it may have an amount greater than its net assets subject to market risk). Should market values of the fund’s portfolio securities decline while the fund is in a leveraged position, greater depreciation of its net assets would likely occur than if it were not in such a position. After a transaction is entered into, the fund may still dispose of or renegotiate the transaction. Additionally, prior to receiving delivery of securities as part of a transaction, the fund may sell such securities.

When the fund enters into a TBA commitment for the sale of mortgage-backed securities for a fixed price, with payment and delivery on an agreed upon future settlement date (which may be referred to as having a short position in such TBA securities), the fund may or may not hold the types of mortgage-backed securities required to be delivered. To the extent the fund has sold such a security on a when-issued, delayed delivery, or forward commitment basis, the fund would not participate in future gains or losses with respect to the security if the fund holds such security. If the other party to a transaction fails to pay for the securities, the fund could suffer a loss. Additionally, when selling a security on a when-issued, delayed delivery or forward commitment basis without owning the security, the fund will incur a loss if the security’s price appreciates in value such that the security’s price is above the agreed-upon price on the settlement date.

Under the SEC’s rule applicable to the fund’s use of derivatives, when issued, forward-settling and nonstandard settlement cycle securities, as well as TBAs and roll transactions, will be treated as derivatives unless the fund intends to physically settle these transactions and the transactions will settle within 35 days of their respective trade dates.

Cybersecurity risks — With the increased use of technologies such as the Internet to conduct business, the fund has become potentially more susceptible to operational and information security risks through breaches in cybersecurity. In general, a breach in cybersecurity can result from either a deliberate attack or an unintentional event. Cybersecurity breaches may involve, among other things, “ransomware” attacks, injection of computer viruses or malicious software code, or the use of vulnerabilities in code to gain unauthorized access to digital information systems, networks or devices that are used directly or indirectly by the fund or its service providers through “hacking” or other means. Cybersecurity risks also include the risk of losses of service resulting from external attacks that do not require unauthorized access to the fund’s systems, networks or devices. For example, denial-of-service attacks on the investment adviser’s or an affiliate’s website could effectively render the fund’s network services unavailable to fund shareholders and other intended end-users. Any such cybersecurity breaches or losses of service may, among other things, cause the fund to lose proprietary information, suffer data corruption or lose operational capacity, or may result in the misappropriation, unauthorized release or other misuse of the fund’s assets or sensitive information (including shareholder personal information or other confidential information), the inability of fund shareholders to transact business, or the destruction of the fund’s physical infrastructure, equipment or operating systems. These, in turn, could cause the fund to violate applicable privacy and other laws and incur or suffer regulatory penalties, reputational damage, additional costs (including compliance costs) associated with corrective measures and/or financial loss. While the fund and its investment adviser have established business continuity plans and risk management systems designed to prevent or reduce the impact of cybersecurity attacks, there are inherent limitations in such plans and systems due in part to the ever-changing nature of technology and cybersecurity attack tactics, and there is a possibility that certain risks have not been adequately identified or prepared for.

In addition, cybersecurity failures by or breaches of the fund’s third-party service providers (including, but not limited to, the fund’s investment adviser, transfer agent, custodian, administrators and other financial intermediaries) may disrupt the business operations of the service providers and of the fund, potentially resulting in financial losses, the inability of fund shareholders to transact business with the fund and of the fund to process transactions, the inability of the fund to calculate its net asset value, violations of applicable privacy and other laws, rules and regulations, regulatory fines, penalties, reputational damage, reimbursement or other compensatory costs and/or additional compliance costs associated with implementation of any corrective measures. The fund and its shareholders could be negatively impacted as a result of any such cybersecurity breaches, and there can be no assurance that the fund will not suffer losses relating to cybersecurity attacks or other informational security breaches affecting the fund’s third-party service providers in the future, particularly as the fund cannot control any cybersecurity plans or systems implemented by such service providers.

Cybersecurity risks may also impact issuers of securities in which the fund invests, which may cause the fund’s investments in such issuers to lose value.

Inflation/Deflation risk — The fund may be subject to inflation and deflation risk. Inflation risk is the risk that the present value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the fund‘s assets can decline. Deflation risk is the risk that prices throughout the economy decline over time. Deflation or inflation may have an adverse effect on the creditworthiness of issuers and may make issuer default more likely, which may result in a decline in the value of the fund‘s assets.

Interfund borrowing and lending — Pursuant to an exemptive order issued by the U.S. Securities and Exchange Commission, the fund may lend money to, and borrow money from, other funds advised by Capital Research and Management Company or its affiliates. The fund will borrow through the program only when the costs are equal to or lower than the costs of bank loans. The fund will lend through the program only when the returns are higher than those available from an investment in repurchase agreements. Interfund loans and borrowings normally extend overnight, but can have a maximum duration of seven days. Loans may be called on one day's notice. The fund may have to

The Income Fund of America — Page 33

borrow from a bank at a higher interest rate if an interfund loan is called or not renewed. Any delay in repayment to a lending fund could result in a lost investment opportunity or additional borrowing costs.

Affiliated investment companies — The fund may purchase shares of certain other investment companies managed by the investment adviser or its affiliates (“Central Funds”). The risks of owning another investment company are similar to the risks of investing directly in the securities in which that investment company invests. Investments in other investment companies could allow the fund to obtain the benefits of a more diversified portfolio than might otherwise be available through direct investments in a particular asset class, and will subject the fund to the risks associated with the particular asset class or asset classes in which an underlying fund invests. However, an investment company may not achieve its investment objective or execute its investment strategy effectively, which may adversely affect the fund’s performance. Any investment in another investment company will be consistent with the fund’s objective(s) and applicable regulatory limitations. Central Funds do not charge management fees. As a result, the fund does not bear additional management fees when investing in Central Funds, but the fund does bear its proportionate share of Central Fund expenses.

Securities lending activities – The fund may lend portfolio securities to brokers, dealers or other institutions that provide cash or U.S. Treasury securities as collateral in an amount at least equal to the value of the securities loaned. While portfolio securities are on loan, the fund will continue to receive the equivalent of the interest and the dividends or other distributions paid by the issuer on the securities, as well as a portion of the interest on the investment of the collateral. Additionally, although the fund will not have the right to vote on securities while they are on loan, the fund has a right to consent on corporate actions and a right to recall each loan to vote on proposals, including proposals involving material events affecting securities loaned. The fund has delegated the decision to lend portfolio securities to the investment adviser. The adviser also has the discretion to consent on corporate actions and to recall securities on loan to vote. In the event the adviser deems a corporate action or proxy vote material, as determined by the adviser based on factors relevant to the fund, it will use reasonable efforts to recall the securities and consent to or vote on the matter.

Securities lending involves risks, including the risk that the loaned securities may not be returned in a timely manner or at all, which would interfere with the fund’s ability to vote proxies or settle transactions, and/or the risk of a counterparty default. Additionally, the fund may lose money from the reinvestment of collateral received on loaned securities in investments that decline in value, default or do not perform as expected. The fund will make loans only to parties deemed by the fund’s adviser to be in good standing and when, in the adviser’s judgment, the income earned would justify the risks.

JPMorgan Chase Bank, N.A. (“JPMorgan”) serves as securities lending agent for the fund. As the securities lending agent, JPMorgan administers the fund’s securities lending program pursuant to the terms of a securities lending agent agreement entered into between the fund and JPMorgan. Under the terms of the agreement, JPMorgan is responsible for making available to approved borrowers securities from the fund’s portfolio. JPMorgan is also responsible for the administration and management of the fund’s securities lending program, including the preparation and execution of an agreement with each borrower governing the terms and conditions of any securities loan, ensuring that securities loans are properly coordinated and documented, ensuring that loaned securities are valued daily and that the corresponding required collateral is delivered by the borrowers, arranging for the investment of collateral received from borrowers, and arranging for the return of loaned securities to the fund in accordance with the fund’s instructions or at loan termination. As compensation for its services, JPMorgan receives a portion of the amount earned by the fund for lending securities.

The following table sets forth, for the fund’s most recently completed fiscal year, the fund’s dollar amount of income and fees and/or other compensation related to its securities lending activities. Net

Portfolio turnover — Portfolio changes will be made without regard to the length of time particular investments may have been held. Short-term trading profits are not the fund’s objective, and changes in its investments are generally accomplished gradually, though short-term transactions may occasionally be made. Higher portfolio turnover may involve correspondingly greater transaction costs in the form of dealer spreads or brokerage commissions. It may also result in the realization of net capital gains, which are taxable when distributed to shareholders, unless the shareholder is exempt from taxation or his or her account is tax-favored.

Fixed income securities are generally traded on a net basis and usually neither brokerage commissions nor transfer taxes are involved. Transaction costs are usually reflected in the spread between the bid and asked price.

The fund’s portfolio turnover rates for the fiscal years ended July 31, 2025 and 2024 were 65% and 92%, respectively. The fund's portfolio turnover rates excluding mortgage dollar roll transactions for the fiscal years ended July 31, 2025 and 2024 were 44% and 43%, respectively. See "Forward commitment, when issued and delayed delivery transactions" above for more information on mortgage dollar rolls. Variations in turnover rates are due to changes in trading activity during the period. The portfolio turnover rate would equal 100% if each security in a fund’s portfolio were replaced once per year.

Fund policies

All percentage limitations in the following fund policies are considered at the time securities are purchased and are based on the fund’s net assets (excluding, for the avoidance of doubt, collateral held in connection with securities lending activities) unless otherwise indicated. None of the following policies involving a maximum percentage of assets will be considered violated unless the excess occurs immediately after, and is caused by, an acquisition by the fund. In managing the fund, the fund’s investment adviser may apply more restrictive policies than those listed below.

Fundamental policies — The fund has adopted the following policies, which may not be changed without approval by holders of a majority of its outstanding shares. Such majority is currently defined in the Investment Company Act of 1940, as amended (the “1940 Act”), as the vote of the lesser of (a) 67% or more of the voting securities present at a shareholder meeting, if the holders of more than 50% of the outstanding voting securities are present in person or by proxy, or (b) more than 50% of the outstanding voting securities.

1. Except as permitted by (i) the 1940 Act and the rules and regulations thereunder, or other successor law governing the regulation of registered investment companies, or interpretations or modifications thereof by the U.S. Securities and Exchange Commission (“SEC”), SEC staff or other authority of competent jurisdiction, or (ii) exemptive or other relief or permission from the SEC, SEC staff or other authority of competent jurisdiction, the fund may not:

a. Borrow money;

b. Issue senior securities;

c. Underwrite the securities of other issuers;

d. Purchase or sell real estate or commodities;

e. Make loans; or

f. Purchase the securities of any issuer if, as a result of such purchase, the fund’s investments would be concentrated in any particular industry.

2. The fund may not invest in companies for the purpose of exercising control or management.

Nonfundamental policies — The following policy may be changed without shareholder approval:

The fund may not acquire securities of open-end investment companies or unit investment trusts registered under the 1940 Act in reliance on Sections 12(d)(1)(F) or 12(d)(1)(G) of the 1940 Act.

The Income Fund of America — Page 37

Additional information about the fund‘s policies — The information below is not part of the fund’s fundamental or nonfundamental policies. This information is intended to provide a summary of what is currently required or permitted by the 1940 Act and the rules and regulations thereunder, or by the interpretive guidance thereof by the SEC or SEC staff, for particular fundamental policies of the fund. Information is also provided regarding the fund’s current intention with respect to certain investment practices permitted by the 1940 Act.

For purposes of fundamental policy 1a, the fund may borrow money in amounts of up to 33-1/3% of its total assets from banks for any purpose. Additionally, the fund may borrow up to 5% of its total assets from banks or other lenders for temporary purposes (a loan is presumed to be for temporary purposes if it is repaid within 60 days and is not extended or renewed). The percentage limitations in this policy are considered at the time of borrowing and thereafter.

For purposes of fundamental policies 1a and 1e, the fund may borrow money from, or loan money to, other funds managed by Capital Research and Management Company or its affiliates to the extent permitted by applicable law and an exemptive order issued by the SEC.

For purposes of fundamental policy 1b, a senior security does not include any promissory note or evidence of indebtedness if such loan is for temporary purposes only and in an amount not exceeding 5% of the value of the total assets of the fund at the time the loan is made (a loan is presumed to be for temporary purposes if it is repaid within 60 days and is not extended or renewed). Further, the fund is permitted to enter into derivatives and certain other transactions, notwithstanding the prohibitions and restrictions on the issuance of senior securities under the 1940 Act, in accordance with current SEC rules and interpretations.

For purposes of fundamental policy 1c, the policy will not apply to the fund to the extent the fund may be deemed an underwriter within the meaning of the 1933 Act in connection with the purchase and sale of fund portfolio securities in the ordinary course of pursuing its investment objective(s) and strategies.

For purposes of fundamental policy 1e, the fund may not lend more than 33-1/3% of its total assets, provided that this limitation shall not apply to the fund’s purchase of debt obligations.

For purposes of fundamental policy 1f, the fund may not invest more than 25% of its total assets in the securities of issuers in a particular industry. This policy does not apply to investments in securities of the U.S. government, its agencies or U.S. government sponsored enterprises or repurchase agreements with respect thereto. For purposes of this policy, with respect to a private activity municipal bond the principal and interest payments of which are derived primarily from the assets and revenues of a non-governmental entity, the fund will look to such non-governmental entity to determine the industry to which the investment should be allocated.

Management of the fund

Board of trustees and officers

Independent trustees¹

The fund’s nominating and governance committee and board select independent trustees with a view toward constituting a board that, as a body, possesses the qualifications, skills, attributes and experience to appropriately oversee the actions of the fund’s service providers, decide upon matters of general policy and represent the long-term interests of fund shareholders. In doing so, they consider the qualifications, skills, attributes and experience of the current board members, with a view toward maintaining a board that is diverse in viewpoint, experience, education and skills.

The fund seeks independent trustees who have high ethical standards and the highest levels of integrity and commitment, who have inquiring and independent minds, mature judgment, good communication skills, and other complementary personal qualifications and skills that enable them to function effectively in the context of the fund’s board and committee structure and who have the ability and willingness to dedicate sufficient time to effectively fulfill their duties and responsibilities.

Each independent trustee has a significant record of accomplishments in governance, business, not-for-profit organizations, government service, academia, law, accounting or other professions. Although no single list could identify all experience upon which the fund’s independent trustees draw in connection with their service, the following table summarizes key experience for each independent trustee. These references to the qualifications, attributes and skills of the trustees are pursuant to the disclosure requirements of the SEC, and shall not be deemed to impose any greater responsibility or liability on any trustee or the board as a whole. Notwithstanding the accomplishments listed below, none of the independent trustees is considered an “expert” within the meaning of the federal securities laws with respect to information in the fund’s registration statement.

³ Eligible trustees may defer their compensation under a nonqualified deferred compensation plan. Amounts deferred by the trustee accumulate at an earnings rate determined by the total return of one or more American Funds as designated by the trustee.

The Income Fund of America — Page 46

Trustee compensation — No compensation is paid by the fund to any officer or trustee who is a director, officer or employee of the investment adviser or its affiliates. Except for the independent trustees listed in the “Board of trustees and officers — Independent trustees” table under the “Management of the fund” section in this statement of additional information, all other officers and trustees of the fund are directors, officers or employees of the investment adviser or its affiliates. The board typically meets either individually or jointly with the boards of one or more other such funds with substantially overlapping board membership (in each case referred to as a “board cluster”). The fund typically pays each independent trustee an annual retainer fee based primarily on the total number of board clusters which that independent trustee serves. Board and committee chairs receive additional fees for their services.

The fund and the other funds served by each independent trustee each pay a portion of these fees.

No pension or retirement benefits are accrued as part of fund expenses. Generally, independent trustees may elect, on a voluntary basis, to defer all or a portion of their fees through a deferred compensation plan in effect for the fund. The fund also reimburses certain expenses of the independent trustees.

Trustee compensation earned during the fiscal year ended July 31, 2025:


Name	Aggregate compensation (including voluntarily deferred compensation¹) from the fund	Total compensation (including voluntarily deferred compensation¹) from all funds managed by Capital Research and Management Company or its affiliates
Gina F. Adams²	$64,589	$342,000
Michael C. Camuñez²	67,989	342,000

Sharon I. Meers²	67,989	373,000
Josette Sheeran²	53,882	402,000
Margaret Spellings²	53,882	538,000

¹ Amounts may be deferred by eligible trustees under a nonqualified deferred compensation plan adopted by the fund in 1993. Deferred amounts accumulate at an earnings rate determined by the total return of one or more American Funds as designated by the trustees. Compensation shown in this table for the fiscal year ended July 31, 2025 does not include earnings on amounts deferred in previous fiscal years. See footnote 2 to this table for more information.

² Since the deferred compensation plan’s adoption, the total amount of deferred compensation accrued by the fund (plus earnings thereon) through the end of the 2025 fiscal year for participating trustees is as follows: Gina F. Adams ($148,514), Michael C. Camuñez ($135,578), Nariman Farvardin ($262,377), William D. Jones ($373,255), Sharon I. Meers ($300,016), Josette Sheeran ($239,656) and Margaret Spellings ($271,891). Amounts deferred and accumulated earnings thereon are not funded and are general unsecured liabilities of the fund until paid to the trustees.

Fund organization and the board of trustees — The fund, an open-end, diversified management investment company, was organized as a Delaware corporation on March 8, 1969, reorganized as a Maryland corporation on December 16, 1983, and reorganized as a Delaware statutory trust on October 1, 2010. All fund operations are supervised by the fund’s board of trustees which meets periodically and performs duties required by applicable state and federal laws.

Delaware law charges trustees with the duty of managing the business affairs of the trust. Trustees are considered to be fiduciaries of the trust and owe duties of care and loyalty to the trust and its shareholders.

Independent board members are paid certain fees for services rendered to the fund as described above. They may elect to defer all or a portion of these fees through a deferred compensation plan in effect for the fund.

The fund has several different classes of shares. Shares of each class represent an interest in the same investment portfolio. Each class has pro rata rights as to voting, redemption, dividends and liquidation, except that each class bears different distribution expenses and may bear different transfer agent fees and other expenses properly attributable to the particular class as approved by the board of trustees and set forth in the fund’s rule 18f-3 Plan. Each class’ shareholders have exclusive voting rights with respect to the respective class’ rule 12b-1 plans adopted in connection with the distribution of shares and on other matters in which the interests of one class are different from interests in another class. Shares of all classes of the fund vote together on matters that affect all classes in substantially the same manner. Each class votes as a class on matters that affect that class alone. Note that 529 college savings plan account owners invested in Class 529 shares are not shareholders of the fund and, accordingly, do not have the rights of a shareholder, such as the right to vote proxies relating to fund shares. As the legal owner of the fund’s Class 529 shares, Commonwealth Savers Plan^SM (formerly, Virginia529) will vote any proxies relating to the fund’s Class 529 shares. In addition, the trustees have the authority to establish new series and classes of shares, and to split or combine outstanding shares into a greater or lesser number, without shareholder approval.

The fund does not hold annual meetings of shareholders. However, significant matters that require shareholder approval, such as certain elections of board members or a change in a fundamental investment policy, will be presented to shareholders at a meeting called for such purpose. Shareholders have one vote per share owned.

The fund’s declaration of trust and by-laws, as well as separate indemnification agreements with independent trustees, provide in effect that, subject to certain conditions, the fund will indemnify its officers and trustees against liabilities or expenses actually and reasonably incurred by them relating to their service to the fund. However, trustees are not protected from liability by reason of their willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of their office.

Removal of trustees by shareholders — At any meeting of shareholders, duly called and at which a quorum is present, shareholders may, by the affirmative vote of the holders of two-thirds of the votes entitled to be cast, remove any trustee from office and may elect a successor or successors to fill any resulting vacancies for the unexpired terms of removed trustees. In addition, the trustees of the fund will promptly call a meeting of shareholders for the purpose of voting upon the removal of any trustees when requested in writing to do so by the record holders of at least 10% of the outstanding shares.

Leadership structure — The board’s chair is currently an independent trustee who is not an “interested person” of the fund within the meaning of the 1940 Act. The board has determined that an independent chair facilitates oversight and enhances the effectiveness of the board. The independent chair’s duties include, without limitation, generally presiding at meetings of the board, approving

The Income Fund of America — Page 48

board meeting schedules and agendas, leading meetings of the independent trustees in executive session, facilitating communication with committee chairs, and serving as the principal independent trustee contact for fund management and counsel to the independent trustees and the fund.

Risk oversight — Day-to-day management of the fund, including risk management, is the responsibility of the fund’s contractual service providers, including the fund’s investment adviser, principal underwriter/distributor and transfer agent. Each of these entities is responsible for specific portions of the fund’s operations, including the processes and associated risks relating to the fund‘s investments, integrity of cash movements, financial reporting, operations and compliance. The board of trustees oversees the service providers’ discharge of their responsibilities, including the processes they use to manage relevant risks. In that regard, the board receives reports regarding the operations of the fund’s service providers, including risks. For example, the board receives reports from investment professionals regarding risks related to the fund‘s investments and trading. The board also receives compliance reports from the fund’s and the investment adviser’s chief compliance officers addressing certain areas of risk.

Committees of the fund’s board, which are comprised of independent board members, none of whom is an “interested person” of the fund within the meaning of the 1940 Act, as well as joint committees of independent board members of funds managed by Capital Research and Management Company, also explore risk management procedures in particular areas and then report back to the full board. For example, the fund’s audit committee oversees the processes and certain attendant risks relating to financial reporting, valuation of fund assets, and related controls. Similarly, a joint review and advisory committee oversees certain risk controls relating to the fund’s transfer agency services.

Not all risks that may affect the fund can be identified or processes and controls developed to eliminate or mitigate their effect. Moreover, it is necessary to bear certain risks (such as investment-related risks) to achieve the fund‘s objectives. As a result of the foregoing and other factors, the ability of the fund’s service providers to eliminate or mitigate risks is subject to limitations.

Committees of the board of trustees — The fund has an audit committee comprised of Michael C. Camuñez, Vanessa C. L. Chang, Sharon I. Meers and Margaret Spellings. The committee provides oversight regarding the fund’s accounting and financial reporting policies and practices, its internal controls and the internal controls of the fund’s principal service providers. The committee acts as a liaison between the fund’s independent registered public accounting firm and the full board of trustees. The audit committee held five meetings during the 2025 fiscal year.

The fund has a contracts committee comprised of all of its independent board members. The committee’s principal function is to request, review and consider the information deemed necessary to evaluate the terms of certain agreements between the fund and its investment adviser or the investment adviser’s affiliates, such as the Investment Advisory and Service Agreement, Principal Underwriting Agreement, Administrative Services Agreement and Plans of Distribution adopted pursuant to rule 12b-1 under the 1940 Act, that the fund may enter into, renew or continue, and to make its recommendations to the full board of trustees on these matters. The contracts committee held one meeting during the 2025 fiscal year.

The fund has a nominating and governance committee comprised of Gina F. Adams, Nariman Farvardin, William D. Jones, Josette Sheeran and Margaret Spellings. The committee periodically reviews such issues as the board’s composition, responsibilities, committees, compensation and other relevant issues, and recommends any appropriate changes to the full board of trustees. The committee also coordinates annual self-assessments of the board and evaluates, selects and nominates independent trustee candidates to the full board of trustees. While the committee normally is able to identify from its own and other resources an ample number of qualified candidates, it will consider shareholder suggestions of persons to be considered as nominees to fill future vacancies on

The Income Fund of America — Page 49

the board. Such suggestions must be sent in writing to the nominating and governance committee of the fund, addressed to the fund’s secretary, and must be accompanied by complete biographical and occupational data on the prospective nominee, along with a written consent of the prospective nominee for consideration of his or her name by the committee. The nominating and governance committee held three meetings during the 2025 fiscal year.

Proxy voting procedures and principles — The fund’s investment adviser, in consultation with the fund’s board, has adopted Proxy Voting Procedures and Principles (the “Principles”) with respect to voting proxies of securities held by the fund and other funds advised by the investment adviser or its affiliates. The Principles are reasonably designed to ensure that proxies are voted solely in accordance with the financial interest of the clients of the investment adviser or its affiliates and the shareholders of the funds advised or managed by the investment adviser or its affiliates. The complete text of the Principles is available at capitalgroup.com. Final voting authority is held by a committee of the appropriate equity investment division of the investment adviser under authority delegated by the funds’ boards. The boards of funds advised by Capital Research and Management Company and its affiliates, including American Funds and Capital Group exchange-traded funds, have established a Joint Proxy Committee (“JPC”) composed of independent board members from each applicable fund board. The JPC’s role is to facilitate appropriate oversight of the proxy voting process and provide valuable input on corporate governance and related matters.

The Principles provide an important framework for analysis and decision-making by all funds. However, they are not exhaustive and do not address all potential issues. The Principles provide a certain amount of flexibility so that all relevant facts and circumstances can be considered in connection with every vote. As a result, each proxy received is voted on a case-by-case basis considering the specific circumstances of each proposal. The voting process reflects the funds’ understanding of the company’s business, its management and its relationship with shareholders over time. In all cases, long-term value creation and the investment objectives and policies of the funds managed by the investment adviser remain the focus.

The investment adviser seeks to vote all U.S. proxies. Proxies for companies outside the United States are also voted where there is sufficient time and information available, taking into account distinct market practices, regulations and laws, and types of proposals presented in each country. Where there is insufficient proxy and meeting agenda information available, the investment adviser will generally vote against such proposals in the interest of encouraging improved disclosure for investors. The investment adviser may not exercise its voting authority if voting would impose costs on clients, including opportunity costs. For example, certain regulators have granted investment limit relief to the investment adviser and its affiliates, conditioned upon limiting voting power to specific voting ceilings. To comply with these voting ceilings, the investment adviser will scale back its votes across all funds and accounts it manages on a pro rata basis based on assets. In addition, certain countries impose restrictions on the ability of shareholders to sell shares during the proxy solicitation period. The investment adviser may choose, due to liquidity issues, not to expose the funds and accounts it manages to such restrictions and may not vote some (or all) shares. Finally, the investment adviser may determine not to recall securities on loan to exercise its voting rights when it determines that the cost of doing so would exceed the benefits to clients or that the vote would not have a material impact on the investment. Proxies with respect to securities on loan through client-directed lending programs are not available to vote and therefore are not voted.

After a proxy statement is received, the investment adviser’s stewardship and engagement team prepares a summary of the proposals contained in the proxy statement.

Investment analysts are generally responsible for making voting recommendations for their investment division on significant votes that relate to companies in their coverage areas. Analysts also have the opportunity to review initial recommendations made by the investment adviser’s stewardship and engagement team. Depending on the vote recommendation, a second opinion may be made by a

The Income Fund of America — Page 50

proxy coordinator (an investment professional with experience in corporate governance and proxy voting matters) within the appropriate investment division, based on knowledge of the Principles and familiarity with proxy-related issues. Each of the investment adviser’s equity investment divisions has its own proxy voting committee, which is made up of investment professionals within each division. Each division’s proxy voting committee retains final authority for voting decisions made by such division. In cases where a fund is co-managed and a security is held by more than one of the investment adviser’s equity investment divisions, the divisions may develop different voting recommendations for individual ballot proposals. If this occurs, and if permitted by local market conventions, the fund’s position will generally be voted proportionally by divisional holding, according to their respective decisions. Otherwise, the outcome will be determined by the equity investment division or divisions with the larger position in the security as of the record date for the shareholder meeting.

In addition to its proprietary proxy voting, governance and executive compensation research, Capital Research and Management Company may utilize research provided by third-party advisory firms on a case-by-case basis. It does not, as a policy, follow the voting recommendations provided by these firms. It periodically assesses the information provided by the advisory firms and reports to the applicable governance committees that provide oversight of the application of the Principles.

From time to time, the investment adviser may vote proxies issued by, or on proposals sponsored or publicly supported by, (a) a client with substantial assets managed by the investment adviser or its affiliates, (b) an entity with a significant business relationship with The Capital Group Companies, Inc. or its affiliates, or (c) a company with a director of an American Fund on its board (each referred to as an “Interested Party”). Other persons or entities may also be deemed an Interested Party if facts or circumstances appear to give rise to a potential conflict.

The investment adviser has developed procedures to identify and address instances when a vote could appear to be influenced by such a relationship. Each equity investment division of the investment adviser has established a Special Review Committee (“SRC”) of senior investment professionals and legal and compliance professionals with oversight of potentially conflicted matters.

If a potential conflict is identified according to the procedure above, the SRC will take appropriate steps to address the conflict of interest. These steps may include engaging an independent third party to review the proxy and using the Principles to provide an independent voting recommendation to the investment adviser for vote execution. The investment adviser will generally follow the third party’s recommendation, except when it believes the recommendation is inconsistent with the investment adviser’s fiduciary duty to its clients. Occasionally, it may not be feasible to engage the third party to review the matter due to compressed timeframes or other operational issues. In this case, the SRC will take appropriate steps to address the conflict of interest, including reviewing the proxy after being provided with a summary of any relevant communications with the Interested Party, the rationale for the voting decision, information on the organization’s relationship with the Interested Party and any other pertinent information.

Information regarding how the fund voted proxies relating to portfolio securities during the 12-month period ended June 30 of each year will be available on or about September 1 of such year (a) without charge, upon request by calling American Funds Service Company at (800) 421-4225, (b) on the Capital Group website and (c) on the SEC’s website at sec.gov.

The following summary sets forth the general positions of the investment adviser on various proposals. A copy of the full Principles is available upon request, free of charge, by calling American Funds Service Company or visiting the Capital Group website.

Director matters — The election of a company’s slate of nominees for director generally is supported. Votes may be withheld for some or all of the nominees if this is determined to be in

The Income Fund of America — Page 51

the best interest of shareholders or if, in the opinion of the investment adviser, such nominee has not fulfilled his or her fiduciary duty. In making this determination, the investment adviser considers, among other things, a nominee’s potential conflicts of interest, track record (whether in the current board seat or in previous executive or director roles) with respect to shareholder protection and value creation as well as their capacity for full engagement on board matters. The investment adviser generally supports a breadth of experience and perspectives among board members, and the separation of the chairman and CEO positions.

Governance provisions — Proposals to declassify a board (elect all directors annually) generally are supported based on the belief that this increases the directors’ sense of accountability to shareholders. Proposals for cumulative voting generally are supported in order to promote management and board accountability and an opportunity for leadership change. Proposals designed to make director elections more meaningful, either by requiring a majority vote or by requiring any director receiving more withhold votes than affirmative votes to tender his or her resignation, generally are supported.

Shareholder rights — Proposals to repeal an existing poison pill generally are supported. (There may be certain circumstances, however, when a proxy voting committee of a fund or an investment division of the investment adviser believes that a company needs to maintain anti-takeover protection.) Proposals to eliminate the right of shareholders to act by written consent or to take away a shareholder’s right to call a special meeting typically are not supported.

Compensation and benefit plans — Equity incentive plans are complicated, and many factors are considered in evaluating a plan. Each plan is evaluated based on protecting shareholder interests and a knowledge of the company and its management. Considerations include the pricing (or repricing) of options awarded under the plan and the impact of dilution on existing shareholders from past and future equity awards. Compensation packages should be structured to attract, motivate and retain existing employees and qualified directors; in addition, they should be aligned with the long-term success of the company and the enhancement of shareholder value.

Routine matters — The ratification of auditors, procedural matters relating to the annual meeting and changes to company name are examples of items considered routine. Such items generally are voted in favor of management’s recommendations unless circumstances indicate otherwise.

Shareholder proposals on environmental and social issues — The investment adviser believes environmental and social issues present investment risks and opportunities that can shape a company’s long-term financial sustainability. Shareholder proposals, including those relating to social and environmental issues, are evaluated in terms of their materiality to the company and its ability to generate long-term value in light of the company’s business model specific operating context. The investment adviser generally supports transparency and standardized disclosure, particularly that which leverages existing regulatory reporting or industry best practices. With respect to environmental matters, this includes disclosures aligned with industry standards and reporting on sustainability issues that are material to investment analysis. With respect to social matters, the investment adviser encourages companies to disclose the composition of the workforce in a regionally appropriate manner. The investment adviser supports relevant reporting and disclosure that is consistent with broadly applicable standards.

Investment adviser — Capital Research and Management Company, the fund’s investment adviser, founded in 1931, maintains research facilities in the United States and abroad (Geneva, Hong Kong, London, Los Angeles, Mumbai, New York, San Francisco, Singapore, Tokyo, Toronto and Washington, D.C.). These facilities are staffed with experienced investment professionals. The investment adviser is located at 333 South Hope Street, Los Angeles, CA 90071. It is a wholly owned subsidiary of The Capital Group Companies, Inc., a holding company for several investment management subsidiaries. Capital Research and Management Company manages equity assets through three equity investment divisions and fixed income assets through its fixed income investment division, Capital Fixed Income Investors. The three equity investment divisions — Capital World Investors, Capital Research Global Investors and Capital International Investors — make investment decisions independently of one another. Portfolio managers in Capital International Investors rely on a research team that also provides investment services to institutional clients and other accounts advised by affiliates of Capital Research and Management Company. The investment adviser, which is deemed under the Commodity Exchange Act (the “CEA”) to be the operator of the fund, has claimed an exclusion from the definition of the term commodity pool operator under the CEA with respect to the fund and, therefore, is not subject to registration or regulation as such under the CEA with respect to the fund.

The investment adviser has adopted policies and procedures that address issues that may arise as a result of an investment professional’s management of the fund and other funds and accounts. Potential issues could involve allocation of investment opportunities and trades among funds and accounts, use of information regarding the timing of fund trades, investment professional compensation and voting relating to portfolio securities. The investment adviser believes that its policies and procedures are reasonably designed to address these issues.

Compensation of investment professionals — As described in the prospectus, the investment adviser uses a system of multiple portfolio managers in managing fund assets. In addition, Capital Research and Management Company’s investment analysts may make investment decisions with respect to a portion of a fund’s portfolio within their research coverage.

Portfolio managers and investment analysts are paid competitive salaries by Capital Research and Management Company. In addition, they may receive bonuses based on their individual portfolio results. Investment professionals also may participate in profit-sharing plans. The relative mix of compensation represented by bonuses, salary and profit-sharing plans will vary depending on the individual’s portfolio results, contributions to the organization and other factors.

To encourage a long-term focus, bonuses based on investment results are calculated by comparing total investment returns to relevant benchmarks over the most recent one-, three-, five- and eight-year periods, with increasing weight placed on each succeeding measurement period. For portfolio managers, benchmarks may include measures of the marketplaces in which the fund invests and measures of the results of comparable mutual funds. For investment analysts, benchmarks may include relevant market measures and appropriate industry or sector indexes reflecting their areas of expertise. Capital Research and Management Company makes periodic subjective assessments of analysts’ contributions to the investment process and this is an element of their overall compensation. The investment results of each of the fund’s portfolio managers may be measured against one or more benchmarks, depending on his or her investment focus, such as (i) MSCI USA Index screened by yield, (ii) Bloomberg U.S. Corporate High Yield Index 2% Issuer Cap, (iii) Bloomberg U.S. Aggregate Index, (iv) MSCI All Country World ex USA Index screened by yield, (v) Bloomberg U.S. Corporate High Yield BB Only Index and (vi) a custom average consisting of funds that disclose investment objectives and strategies comparable to those of the fund. From time to time, Capital Research and Management Company may adjust or customize these benchmarks to better reflect the investment objective(s) of the fund and/or the universe of comparably managed funds of competitive investment management firms.

³ Personal brokerage accounts of portfolio managers and their families are not reflected.

The fund’s investment adviser has adopted policies and procedures to mitigate material conflicts of interest that may arise in connection with a portfolio manager’s management of the fund, on the one hand, and investments in the other pooled investment vehicles and other accounts, on the other hand, such as material conflicts relating to the allocation of investment opportunities that may be suitable for both the fund and such other accounts.

Investment Advisory and Service Agreement — The Investment Advisory and Service Agreement (the “Agreement”) between the fund and the investment adviser will continue in effect until January 31, 2026, unless sooner terminated, and may be renewed from year to year thereafter, provided that any such renewal has been specifically approved at least annually by (a) the board of trustees, or by the vote of a majority (as defined in the 1940 Act) of the outstanding voting securities of the fund, and (b) the vote of a majority of trustees who are not parties to the Agreement or interested persons (as defined in the 1940 Act) of any such party, in accordance with applicable laws and regulations. The Agreement provides that the investment adviser has no liability to the fund for its acts or omissions in the performance of its obligations to the fund not involving willful misconduct, bad faith, gross negligence or reckless disregard of its obligations under the Agreement. The Agreement also provides that either party has the right to terminate it, without penalty, upon 60 days’ written notice to the other party, and that the Agreement automatically terminates in the event of its assignment (as defined in the 1940 Act). In addition, the Agreement provides that the investment adviser may delegate all, or a portion of, its investment management responsibilities to one or more subsidiary advisers approved by the fund’s board, pursuant to an agreement between the investment adviser and such subsidiary. Any such subsidiary adviser will be paid solely by the investment adviser out of its fees.

In addition to providing investment advisory services, the investment adviser furnishes the services and pays the compensation and travel expenses of persons to perform the fund’s executive, administrative, clerical and bookkeeping functions, and provides suitable office space, necessary small office equipment and utilities, general purpose accounting forms, supplies and postage used at the fund’s offices. The fund pays all expenses not assumed by the investment adviser, including, but not limited to: custodian, stock transfer and dividend disbursing fees and expenses; shareholder recordkeeping and administrative expenses; costs of the designing, printing and mailing of reports, prospectuses, proxy statements and notices to its shareholders; taxes; expenses of the issuance and redemption of fund shares (including stock certificates, registration and qualification fees and expenses); expenses pursuant to the fund’s plans of distribution (described below); legal and auditing expenses; compensation, fees and expenses paid to independent trustees; association dues; costs of stationery and forms prepared exclusively for the fund; and costs of assembling and storing shareholder account data.

For the purposes of such computations under the Agreement, the fund’s gross investment income is determined in accordance with generally accepted accounting principles and does not reflect any net realized gains or losses on the sale of portfolio securities.

For the fiscal years ended July 31, 2025, 2024 and 2023, the investment adviser earned from the fund management fees of $285,375,000, $270,340,000 and $266,872,000, respectively.

Administrative services — The investment adviser and its affiliates provide certain administrative services for shareholders of the fund’s Class A, C, T, F, R and 529 shares. Administrative services are provided by the investment adviser and its affiliates to help assist third parties providing non-distribution services to fund shareholders. These services include providing in-depth information on the fund and market developments that impact fund investments. Administrative services also include, but are not limited to, coordinating, monitoring and overseeing third parties that provide services to fund shareholders.

These services are provided pursuant to an Administrative Services Agreement (the “Administrative Agreement”) between the fund and the investment adviser relating to the fund’s Class A, C, T, F, R and 529 shares. The Administrative Agreement will continue in effect until January 31, 2026, unless sooner renewed or terminated, and may be renewed from year to year thereafter, provided that any such renewal has been specifically approved by the vote of a majority of the members of the fund’s board who are not parties to the Administrative Agreement or interested persons (as defined in the 1940 Act) of any such party. The fund may terminate the Administrative Agreement at any time by vote of a majority of independent board members. The investment adviser has the right to terminate the Administrative Agreement upon 60 days’ written notice to the fund. The Administrative Agreement automatically terminates in the event of its assignment (as defined in the 1940 Act).

The Administrative Services Agreement between the fund and the investment adviser provides the fund the ability to charge an administrative services fee of .05% for all share classes. The fund’s investment adviser receives an administrative services fee at the annual rate of .03% of the average daily net assets of the fund attributable to each of the share classes (which could be increased as noted above) for its provision of administrative services. Administrative services fees are paid monthly and accrued daily.

Plans of distribution — The fund has adopted plans of distribution (the “Plans”) pursuant to rule 12b-1 under the 1940 Act. The Plans permit the fund to expend amounts to finance any activity primarily intended to result in the sale of fund shares, provided the fund’s board of trustees has approved the category of expenses for which payment is being made.

Each Plan is specific to a particular share class of the fund. As the fund has not adopted a Plan for Class F-2, F-3, 529-F-2, 529-F-3, R-5E, R-5 or R-6, no 12b-1 fees are paid from Class F-2, F-3, 529-F-2, 529-F-3, R-5E, R-5 or R-6 share assets and the following disclosure is not applicable to these share classes.

Payments under the Plans may be made for service-related and/or distribution-related expenses. Service-related expenses include paying service fees to qualified dealers. Distribution-related expenses include commissions paid to qualified dealers. The amounts actually paid under the Plans for the past fiscal year, expressed as a percentage of the fund’s average daily net assets attributable to the applicable share class, are disclosed in the prospectus under “Fees and expenses of the fund.” Further information regarding the amounts available under each Plan is in the “Plans of Distribution” section of the prospectus.

The Income Fund of America — Page 63

Following is a brief description of the Plans:

Class A and 529-A — For Class A and 529-A shares, up to .25% of the fund’s average daily net assets attributable to such shares is reimbursed to the Principal Underwriter for paying service-related expenses, and the balance available under the applicable Plan may be paid to the Principal Underwriter for distribution-related expenses. The fund may annually expend up to .25% for Class A shares and up to .50% for Class 529-A shares under the applicable Plan; however, for Class 529-A shares, the board of trustees has approved payments to the Principal Underwriter of up to .25% of the fund’s average daily net assets, in the aggregate, for paying service- and distribution-related expenses.

Distribution-related expenses for Class A and 529-A shares include dealer commissions and wholesaler compensation paid on sales of shares of $1 million or more purchased without a sales charge. Commissions on these “no load” purchases (which are described in further detail under the “Sales Charges” section of this statement of additional information) in excess of the Class A and 529-A Plan limitations and not reimbursed to the Principal Underwriter during the most recent fiscal quarter are recoverable for 15 months, provided that the reimbursement of such commissions does not cause the fund to exceed the annual expense limit. After 15 months, these commissions are not recoverable. As of the fund’s most recent fiscal year, unreimbursed expenses that remained subject to reimbursement under the Plan for Class A shares totaled $7,375,000 or less than 1% of Class A net assets.

Class T and 529-T — For Class T and 529-T shares, the fund may annually expend up to .50% under the applicable Plan; however, the fund’s board of trustees has approved payments to the Principal Underwriter of up to .25% of the fund’s average daily net assets attributable to Class T and 529-T shares for paying service-related expenses.

Other share classes — The Plans for each of the other share classes that have adopted Plans provide for payments to the Principal Underwriter for paying service-related and distribution-related expenses of up to the following amounts of the fund’s average daily net assets attributable to such shares:


Share class	Service related payments¹	Distribution related payments¹	Total allowable under the Plans²
Class C	0.25%	0.75%	1.00%
Class F-1	0.25	—	0.50
Class 529-C	0.25	0.75	1.00
Class 529-E	0.25	0.25	0.75
Class 529-F-1	0.25	—	0.50
Class R-1	0.25	0.75	1.00
Class R-2	0.25	0.50	1.00
Class R-2E	0.25	0.35	0.85
Class R-3	0.25	0.25	0.75
Class R-4	0.25	—	0.50

1 Amounts in these columns represent the amounts approved by the board of trustees under the applicable Plan.

2 The fund may annually expend the amounts set forth in this column under the current Plans with the approval of the board of trustees.

The Income Fund of America — Page 64

Payment of service fees — For purchases of less than $1 million, payment of service fees to investment dealers generally begins accruing immediately after establishment of an account in Class A, C, 529-A or 529-C shares. For purchases of $1 million or more, payment of service fees to investment dealers generally begins accruing 12 months after establishment of an account in Class A or 529-A shares. Service fees are not paid on certain investments made at net asset value including accounts established by registered representatives and their family members as described in the “Sales charges” section of the prospectus.

During the 2025 fiscal year, 12b-1 expenses accrued and paid, and if applicable, unpaid, were:


	12b-1 expenses	12b-1 unpaid liability outstanding

Approval of the Plans — As required by rule 12b-1 and the 1940 Act, the Plans (together with the Principal Underwriting Agreement) have been approved by the full board of trustees and separately by a majority of the independent trustees of the fund who have no direct or indirect financial interest in the operation of the Plans or the Principal Underwriting Agreement. In addition, the selection and nomination of independent trustees of the fund are committed to the discretion of the independent trustees during the existence of the Plans.

Potential benefits of the Plans to the fund and its shareholders include enabling shareholders to obtain advice and other services from a financial professional at a reasonable cost, the likelihood that the Plans will stimulate sales of the fund benefiting the investment process through growth or stability of assets and the ability of shareholders to choose among various alternatives in paying for sales and service. The Plans may not be amended to materially increase the amount spent for distribution without shareholder approval. Plan expenses are reviewed quarterly by the board of trustees and the Plans must be renewed annually by the board of trustees.

A portion of the fund’s 12b-1 expense is paid to financial professionals to compensate them for providing ongoing services. If you have questions regarding your investment in the fund or need assistance with your account, please contact your financial professional. If you need a financial professional, please call Capital Client Group, Inc. at (800) 421-4120 for assistance.

Fee to Commonwealth Savers Plan — Class 529 shares are offered to certain American Funds by Commonwealth Savers Plan through CollegeAmerica and Class ABLE shares are offered to certain American Funds by Commonwealth Savers Plan through ABLEAmerica, a tax-advantaged savings program for individuals with disabilities. As compensation for its oversight and administration of the CollegeAmerica and ABLEAmerica savings plans, Commonwealth Savers Plan is entitled to receive a quarterly fee based on the combined net assets invested in Class 529 shares and Class ABLE shares across all American Funds. The quarterly fee is accrued daily and calculated at the annual rate of .09% on the first $20 billion of net assets invested in American Funds Class 529 shares and Class ABLE shares, .05% on net assets between $20 billion and $75 billion and .03% on net assets over $75 billion. The fee for any given calendar quarter is accrued and calculated on the basis of average net assets of American Funds Class 529 and Class ABLE shares for the last month of the prior calendar quarter. Commonwealth Savers Plan is currently waiving that portion of its fee attributable to Class ABLE shares. Such waiver is expected to remain in effect until the earlier of (a) the date on which total net assets invested in Class ABLE shares reach $300 million and (b) June 30, 2028.

Execution of portfolio transactions

The investment adviser places orders with broker-dealers for the fund’s portfolio transactions. Purchases and sales of equity securities on a securities exchange or an over-the-counter market are effected through broker-dealers who receive commissions for their services. Generally, commissions relating to securities traded on foreign exchanges will be higher than commissions relating to securities traded on U.S. exchanges and may not be subject to negotiation. Equity securities may also be purchased from underwriters at prices that include underwriting fees. Purchases and sales of fixed income securities are generally made with an issuer or a primary market maker acting as principal with no stated brokerage commission. The price paid to an underwriter for fixed income securities includes underwriting fees. Prices for fixed income securities in secondary trades usually include undisclosed compensation to the market maker reflecting the spread between the bid and ask prices for the securities.

In selecting broker-dealers, the investment adviser strives to obtain “best execution” (the most favorable total price reasonably attainable under the circumstances) for the fund’s portfolio transactions, taking into account a variety of factors. These factors include the size and type of transaction, the nature and character of the markets for the security to be purchased or sold, the cost, quality, likely speed and reliability of execution and settlement, the broker-dealer’s or execution venue’s ability to offer liquidity and anonymity and the trade-off between market impact and opportunity costs. The investment adviser considers these factors, which involve qualitative judgments, when selecting broker-dealers and execution venues for fund portfolio transactions. The investment adviser views best execution as a process that should be evaluated over time as part of an overall relationship with particular broker-dealer firms. The investment adviser and its affiliates negotiate commission rates with broker-dealers based on what they believe is reasonably necessary to obtain best execution. They seek, on an ongoing basis, to determine what the reasonable levels of commission rates for execution services are in the marketplace, taking various considerations into account, including the extent to which a broker-dealer has put its own capital at risk, historical commission rates and commission rates that other institutional investors are paying. The fund does not consider the investment adviser as having an obligation to obtain the lowest commission rate available for a portfolio transaction to the exclusion of price, service and qualitative considerations. Brokerage commissions are only a small part of total execution costs and other factors, such as market impact and speed of execution, contribute significantly to overall transaction costs.

The investment adviser may execute portfolio transactions with broker-dealers who provide certain brokerage and/or investment research services to it but only when in the investment adviser’s judgment the broker-dealer is capable of providing best execution for that transaction. The investment adviser makes decisions for procurement of research separately and distinctly from decisions on the choice of brokerage and execution services. The receipt of these research services permits the investment adviser to supplement its own research and analysis and makes available the views of, and information from, individuals and the research staffs of other firms. Such views and information may be provided in the form of written reports, telephone contacts and meetings with securities analysts. These services may include, among other things, reports and other communications with respect to individual companies, industries, countries and regions, economic, political and legal developments, as well as scheduling meetings with corporate executives and seminars and conferences related to relevant subject matters. Research services that the investment adviser receives from broker-dealers may be used by the investment adviser in servicing the fund and other funds and accounts that it advises; however, not all such services will necessarily benefit the fund.

The investment adviser bears the cost of all third-party investment research services for all client accounts it advises. However, in order to compensate certain U.S. broker-dealers for research consumed, and valued, by the investment adviser’s investment professionals, the investment adviser continues to operate a limited commission sharing arrangement with commissions on equity trades for certain registered investment companies it advises. The investment adviser voluntarily reimburses such

The Income Fund of America — Page 69

registered investment companies for all amounts collected into the commission sharing arrangement. In order to operate the commission sharing arrangement, the investment adviser may cause such registered investment companies to pay commissions in excess of what other broker-dealers might have charged for certain portfolio transactions in recognition of brokerage and/or investment research services. In this regard, the investment adviser has adopted a brokerage allocation procedure consistent with the requirements of Section 28(e) of the Securities Exchange Act of 1934. Section 28(e) permits the investment adviser and its affiliates to cause an account to pay a higher commission to a broker-dealer to compensate the broker-dealer or another service provider for certain brokerage and/or investment research services provided to the investment adviser and its affiliates, if the investment adviser and each affiliate makes a good faith determination that such commissions are reasonable in relation to the value of the services provided by such broker-dealer to the investment adviser and its affiliates in terms of that particular transaction or the investment adviser’s overall responsibility to the fund and other accounts that it advises. Certain brokerage and/or investment research services may not necessarily benefit all accounts paying commissions to each such broker-dealer; therefore, the investment adviser and its affiliates assess the reasonableness of commissions in light of the total brokerage and investment research services provided to the investment adviser and its affiliates. Further, investment research services may be used by all investment associates of the investment adviser and its affiliates, regardless of whether they advise accounts with trading activity that generates eligible commissions.

In accordance with their internal brokerage allocation procedure, the investment adviser and its affiliates periodically assess the brokerage and investment research services provided by each broker-dealer and each other service provider from which they receive such services. As part of its ongoing relationships, the investment adviser and its affiliates routinely meet with firms to discuss the level and quality of the brokerage and research services provided, as well as the value and cost of such services. In valuing the brokerage and investment research services the investment adviser and its affiliates receive from broker-dealers and other research providers in connection with its good faith determination of reasonableness, the investment adviser and its affiliates take various factors into consideration, including the quantity, quality and usefulness of the services to the investment adviser and its affiliates. Based on this information and applying their judgment, the investment adviser and its affiliates set an annual research budget.

Research analysts and portfolio managers periodically participate in a research poll to determine the usefulness and value of the research provided by individual broker-dealers and research providers. Based on the results of this research poll, the investment adviser and its affiliates may, through commission sharing arrangements with certain broker-dealers, direct a portion of commissions paid to a broker-dealer by the fund and other registered investment companies managed by the investment adviser or its affiliates to be used to compensate the broker-dealer and/or other research providers for research services they provide. While the investment adviser and its affiliates may negotiate commission rates and enter into commission sharing arrangements with certain broker-dealers with the expectation that such broker-dealers will be providing brokerage and research services, none of the investment adviser, any of its affiliates or any of their clients incurs any obligation to any broker-dealer to pay for research by generating trading commissions. The investment adviser and its affiliates negotiate prices for certain research that may be paid through commission sharing arrangements or by themselves with cash.

When executing portfolio transactions in the same equity security for the funds and accounts, or portions of funds and accounts, over which the investment adviser, through its equity investment divisions, has investment discretion, each investment division within the adviser and its affiliates normally aggregates its respective purchases or sales and executes them as part of the same transaction or series of transactions. When executing portfolio transactions in the same fixed income security for the fund and the other funds or accounts over which it or one of its affiliated companies has investment discretion, the investment adviser normally aggregates such purchases or sales and executes them as part of the same transaction or series of transactions. The objective of aggregating

The Income Fund of America — Page 70

purchases and sales of a security is to allocate executions in an equitable manner among the funds and other accounts that have concurrently authorized a transaction in such security. The investment adviser and its affiliates serve as investment adviser for certain accounts that are designed to be substantially similar to another account. This type of account will often generate a large number of relatively small trades when it is rebalanced to its reference fund due to differing cash flows or when the account is initially started up. The investment adviser may not aggregate program trades or electronic list trades executed as part of this process. Non-aggregated trades performed for these accounts will be allocated entirely to that account. This is done only when the investment adviser believes doing so will not have a material impact on the price or quality of other transactions.

The investment adviser currently owns a minority interest in IEX Group and alternative trading systems, Luminex ATS and LeveL ATS (through a minority interest in their common parent holding company). The investment adviser, or brokers with which the investment adviser places orders, may place orders on these or other exchanges or alternative trading systems in which it, or one of its affiliates, has an ownership interest, provided such ownership interest is less than five percent of the total ownership interests in the entity. The investment adviser is subject to the same best execution obligations when trading on any such exchange or alternative trading systems.

Purchase and sale transactions may be effected directly among and between certain funds or accounts advised by the investment adviser or its affiliates, including the fund. The investment adviser maintains cross-trade policies and procedures and places a cross-trade only when such a trade is in the best interest of all participating clients and is not prohibited by the participating funds’ or accounts’ investment management agreement or applicable law.

The investment adviser may place orders for the fund’s portfolio transactions with broker-dealers who have sold shares of the funds managed by the investment adviser or its affiliated companies; however, it does not consider whether a broker-dealer has sold shares of the funds managed by the investment adviser or its affiliated companies when placing any such orders for the fund’s portfolio transactions.

Purchases and sales of futures contracts for the fund will be effected through executing brokers and FCMs that specialize in the types of futures contracts that the fund expects to hold. The investment adviser will use reasonable efforts to choose executing brokers and FCMs capable of providing the services necessary to obtain the most favorable price and execution available. The full range and quality of services available will be considered in making these determinations. The investment adviser will monitor the executing brokers and FCMs used for purchases and sales of futures contracts for their ability to execute trades based on many factors, such as the sizes of the orders, the difficulty of executions, the operational facilities of the firm involved and other factors.

Forward currency contracts are traded directly between currency traders (usually large commercial banks) and their customers. The cost to the fund of engaging in such contracts varies with factors such as the currency involved, the length of the contract period and the market conditions then prevailing. Because such contracts are entered into on a principal basis, their prices usually include undisclosed compensation to the market maker reflecting the spread between the bid and ask prices for the contracts. The fund may incur additional fees in connection with the purchase or sale of certain contracts.

Brokerage commissions (net of any reimbursements described below) paid on portfolio transactions for the fiscal years ended July 31, 2025, 2024 and 2023 amounted to $20,389,000, $19,512,000 and $17,675,000, respectively. The investment adviser is reimbursing the fund for all amounts collected into the commission sharing arrangement. For the fiscal years ended July 31, 2025, 2024 and 2023, the investment adviser reimbursed the fund $1,458,000, $1,316,000 and $1,110,000, respectively, for commissions paid to broker-dealers through a commission sharing arrangement to compensate such broker-dealers for research services. Changes in the dollar amount of brokerage commissions paid by

The Income Fund of America — Page 71

the fund over the last three fiscal years resulted from changes in the volume of trading activity and/or the amount of commissions used to pay for research services through a commission sharing arrangement.

The fund is required to disclose information regarding investments in the securities of its “regular” broker-dealers (or parent companies of its regular broker-dealers) that derive more than 15% of their revenue from broker-dealer, underwriter or investment adviser activities. A regular broker-dealer is (a) one of the 10 broker-dealers that received from the fund the largest amount of brokerage commissions by participating, directly or indirectly, in the fund’s portfolio transactions during the fund’s most recently completed fiscal year; (b) one of the 10 broker-dealers that engaged as principal in the largest dollar amount of portfolio transactions of the fund during the fund’s most recently completed fiscal year; or (c) one of the 10 broker-dealers that sold the largest amount of securities of the fund during the fund’s most recently completed fiscal year.

At the end of the fund’s most recently completed fiscal year, the fund’s regular broker-dealers included Bank of America, N.A., Citigroup Inc., Deutsche Bank A.G., Goldman Sachs Group, Inc., J.P. Morgan Securities LLC, LPL Holdings, Inc., Morgan Stanley & Co. LLC, RBC Capital Markets LLC, UBS Group AG and Wells Fargo Securities, LLC. As of the fund’s most recently completed fiscal year, the fund held debt and equity securities of Bank of America, N.A. in the amount of $576,635,000, Citigroup Inc. in the amount of $1,467,325,000, Goldman Sachs Group, Inc. in the amount of $714,299,000, J.P. Morgan Securities LLC in the amount of $2,103,307,000, Morgan Stanley & Co. LLC in the amount of $541,979,000 and Wells Fargo Securities, LLC in the amount of $116,632,000. The fund held debt securities of Deutsche Bank A.G. in the amount of $238,964,000, LPL Holdings, Inc. in the amount of $61,685,000, RBC Capital Markets LLC in the amount of $14,368,000 and UBS Group AG in the amount of $57,598,000.

Disclosure of portfolio holdings

The fund’s investment adviser, on behalf of the fund, has adopted policies and procedures with respect to the disclosure of information about fund portfolio securities. These policies and procedures have been reviewed by the fund’s board of trustees, and compliance will be periodically assessed by the board in connection with reporting from the fund’s Chief Compliance Officer.

Under these policies and procedures, the fund’s complete list of portfolio holdings available for public disclosure, dated as of the end of each calendar quarter, is permitted to be posted on the Capital Group website no earlier than the 10th day after such calendar quarter. In practice, the publicly disclosed portfolio is typically posted on the Capital Group website within 30 days after the end of the calendar quarter. The publicly disclosed portfolio may exclude certain securities when deemed to be in the best interest of the fund as permitted by applicable regulations. In addition, the fund’s list of top 10 portfolio holdings measured by percentage of net assets, dated as of the end of each calendar month, is permitted to be posted on the Capital Group website no earlier than the 10th day after such month for equity securities, and no earlier than the 30th day after such month for fixed income securities. The fund’s list of top 10 portfolio holdings for equity and fixed income securities is permitted to be posted no earlier than the 10th day after the final month of each calendar quarter. For multi-asset funds, the fund’s list of top 10 portfolio holdings for equity and fixed income securities is permitted to be posted each month, no earlier than the 10th day after such month. Such portfolio holdings information may be disclosed to any person pursuant to an ongoing arrangement to disclose portfolio holdings information to such person no earlier than one day after the day on which the information is posted on the Capital Group website. The investment adviser may disclose individual holdings more frequently on the Capital Group website if it determines it is in the best interest of the fund.

Certain intermediaries are provided additional information about the fund’s management team, including information on the fund’s portfolio securities they have selected. This information is provided to larger intermediaries that require the information to make the fund available for investment on the firm’s platform. Intermediaries receiving the information are required to keep it confidential and use it only to analyze the fund.

The fund’s custodian, outside counsel, auditor, financial printers, proxy voting and class action claims processing service providers, pricing information vendors, consultants or agents operating under a contract with the investment adviser or its affiliates, co-litigants (such as in connection with a bankruptcy proceeding related to a fund holding) and certain other third parties described below, each of which requires portfolio holdings information for legitimate business and fund oversight purposes, may receive fund portfolio holdings information earlier. See the “General information” section in this statement of additional information for further information about the fund’s custodian, outside counsel and auditor.

The fund‘s portfolio holdings, dated as of the end of each calendar month, are made available to up to 20 key broker-dealer relationships and up to 10 key global consulting firms with research departments to help them evaluate the fund for eligibility on approved lists or in model portfolios. These firms include certain of those listed under the “Other compensation to dealers” section of this statement of additional information and certain broker-dealer firms that offer trading platforms for registered investment advisers. Monthly holdings may be provided to these intermediaries no earlier than the 10th day after the end of the calendar month. In practice, monthly holdings are provided within 30 days after the end of the calendar month. Holdings may also be disclosed more frequently to certain statistical and data collection agencies including Morningstar, Lipper, Inc., Value Line, Vickers Stock Research, Bloomberg and Thomson Financial Research. Intermediaries receiving the information are required to keep it confidential and use it only to analyze the fund.

The Income Fund of America — Page 73

Affiliated persons of the fund, including officers of the fund and employees of the investment adviser and its affiliates, who receive portfolio holdings information are subject to restrictions and limitations on the use and handling of such information pursuant to applicable codes of ethics, including requirements not to trade in securities based on confidential and proprietary investment information, to maintain the confidentiality of such information, and to pre-clear securities trades and report securities transactions activity, as applicable. For more information on these restrictions and limitations, please see the “Code of ethics” section in this statement of additional information and the Code of Ethics. Third-party service providers of the fund and other entities, as described in this statement of additional information, receiving such information are subject to confidentiality obligations and obligations that would prohibit them from trading in securities based on such information. When portfolio holdings information is disclosed other than through the Capital Group website to persons not affiliated with the fund, such persons will be bound by agreements (including confidentiality agreements) or fiduciary or other obligations that restrict and limit their use of the information to legitimate business uses only. None of the fund, its investment adviser or any of their affiliates receives compensation or other consideration in connection with the disclosure of information about portfolio securities.

Subject to board policies, the authority to disclose a fund’s portfolio holdings, and to establish policies with respect to such disclosure, resides with the appropriate investment-related committees of the fund’s investment adviser. In exercising their authority, the committees determine whether disclosure of information about the fund’s portfolio securities is appropriate and in the best interest of fund shareholders. The investment adviser has implemented policies and procedures to address conflicts of interest that may arise from the disclosure of fund holdings. For example, the investment adviser’s code of ethics specifically requires, among other things, the safeguarding of information about fund holdings and contains prohibitions designed to prevent the personal use of confidential, proprietary investment information in a way that would conflict with fund transactions. In addition, the investment adviser believes that its current policy of not selling portfolio holdings information and not disclosing such information to unaffiliated third parties until such holdings have been made public on the Capital Group website (other than to certain fund service providers and other third parties for legitimate business and fund oversight purposes) helps reduce potential conflicts of interest between fund shareholders and the investment adviser and its affiliates.

The fund’s investment adviser and its affiliates provide investment advice to individuals and financial intermediaries that have investment objectives that may be substantially similar to those of the fund. These clients also may have portfolios consisting of holdings substantially similar to those of the fund and generally have access to current portfolio holdings information for their accounts. These clients do not owe the fund’s investment adviser or the fund a duty of confidentiality with respect to disclosure of their portfolio holdings.

The Income Fund of America — Page 74

Price of shares

Shares are purchased at the offering price or sold at the net asset value price next determined after the purchase or sell order is received by the fund or the Transfer Agent provided that your request contains all information and legal documentation necessary to process the transaction. The Transfer Agent may accept written orders for the sale of fund shares on a future date. These orders are subject to the Transfer Agent’s policies, which generally allow shareholders to provide a written request to sell shares at the net asset value on a specified date no more than five business days after receipt of the order by the Transfer Agent. Any request to sell shares on a future date will be rejected if the request is not in writing, if the requested transaction date is more than five business days after the Transfer Agent receives the request or if the request does not contain all information and legal documentation necessary to process the transaction.

The offering or net asset value price is effective for orders received prior to the time of determination of the net asset value and, in the case of orders placed with dealers or their authorized designees, accepted by the Principal Underwriter, the Transfer Agent, a dealer or any of their designees. In the case of orders sent directly to the fund or the Transfer Agent, an investment dealer should be indicated. The dealer is responsible for promptly transmitting purchase and sell orders to the Principal Underwriter.

Prices that appear in newspapers and websites do not always indicate prices at which you will be purchasing and redeeming shares of the fund, since such prices generally reflect the previous day’s closing price, while purchases and redemptions are made at the next calculated price. The price you pay for shares, the offering price, is based on the net asset value per share, which is calculated once daily as of the close of regular trading on the New York Stock Exchange, normally 4 p.m. New York time, each day the New York Stock Exchange is open. If the New York Stock Exchange makes a scheduled (e.g., the day after Thanksgiving) or an unscheduled close prior to 4 p.m. New York time, the net asset value of the fund will be determined at approximately the time the New York Stock Exchange closes on that day. If on such a day market quotations and prices from third-party pricing services are not based as of the time of the early close of the New York Stock Exchange but are as of a later time (up to approximately 4 p.m. New York time), for example because the market remains open after the close of the New York Stock Exchange, those later market quotations and prices will be used in determining the fund’s net asset value.

Orders in good order received after the New York Stock Exchange closes (scheduled or unscheduled) will be processed at the net asset value (plus any applicable sales charge) calculated on the following business day. The New York Stock Exchange is currently closed on weekends and on the following holidays: New Year’s Day; Martin Luther King Jr. Day; Presidents’ Day; Good Friday; Memorial Day; Juneteenth National Independence Day; Independence Day; Labor Day; Thanksgiving Day; and Christmas Day. Each share class of the fund has a separately calculated net asset value (and share price).

Orders received by the investment dealer or authorized designee, the Transfer Agent or the fund after the time of the determination of the net asset value will be entered at the next calculated offering price. Note that investment dealers or other intermediaries may have their own rules about share transactions and may have earlier cut-off times than those of the fund. For more information about how to purchase through your intermediary, contact your intermediary directly.

All portfolio securities of funds managed by Capital Research and Management Company (other than American Funds U.S. Government Money Market Fund) are valued, and the net asset values per share for each share class are determined, as indicated below. The fund follows standard industry practice by typically reflecting changes in its holdings of portfolio securities on the first business day following a portfolio trade.

The Income Fund of America — Page 75

Equity securities, including depositary receipts, exchange-traded funds, and certain convertible preferred stocks that trade on an exchange or market, are generally valued at the official closing price of, or the last reported sale price on, the exchange or market on which such securities are traded, as of the close of business on the day the securities are being valued or, lacking any sales, at the last available bid price. Prices for each security are taken from the principal exchange or market on which the security trades.

Exchange-traded options and futures are generally valued at the official closing price for options and official settlement price for futures on the exchange or market on which such instruments are traded, as of the close of business on the day such instruments are being valued.

Fixed income securities, including short-term securities, are generally valued at evaluated prices obtained from third-party pricing vendors. Vendors value such securities based on one or more inputs that may include, among other things, benchmark yields, transactions, bids, offers, quotations from dealers and trading systems, new issues, underlying equity of the issuer, interest rate volatilities, spreads and other relationships observed in the markets among comparable securities and proprietary pricing models such as yield measures calculated using factors such as cash flows, prepayment information, default rates, delinquency and loss assumptions, financial or collateral characteristics or performance, credit enhancements, liquidation value calculations, specific deal information and other reference data.

Forward currency contracts are valued based on the spot and forward exchange rates obtained from a third-party pricing vendor.

Futures contracts are generally valued at the official settlement price of, or the last reported sale price on, the principal exchange or market on which such instruments are traded, as of the close of business on the day the contracts are being valued or, lacking any sales, at the last available bid price.

Swaps, including interest rate swaps, total return swaps and positions in credit default swap indices, are generally valued using evaluated prices obtained from third-party pricing vendors who calculate these values based on market inputs that may include yields of the indices referenced in the instrument and the relevant curve, dealer quotes, default probabilities and recovery rates, other reference data, and terms of the contract.

Options are valued using market quotations or valuations provided by one or more pricing vendors. Similar to futures, options may also be valued at the official settlement price if listed on an exchange.

Securities and other assets for which representative market quotations are not readily available or are considered unreliable by the investment adviser are valued at fair value as determined in good faith under fair value guidelines adopted by the investment adviser and approved by the fund’s board. Subject to board oversight, the fund’s board has designated the fund’s investment adviser to make fair valuation determinations, which are directed by a valuation committee established by the fund’s investment adviser. The board receives regular reports describing fair valued securities and the valuation methods used.

As a general principle, these guidelines consider relevant company, market and other data and considerations to determine the price that the fund might reasonably expect to receive if such fair valued securities were sold in an orderly transaction. Fair valuations may differ materially from valuations that would have been used had greater market activity occurred. The investment adviser’s valuation committee considers relevant indications of value that are reasonably and timely available to it in determining the fair value to be assigned to a particular security, such as the type and cost of the security, restrictions on resale of the security, relevant financial or business developments of the issuer, actively traded similar or related securities and transactions, dealer or broker quotes, conversion or

The Income Fund of America — Page 76

exchange rights on the security, related corporate actions, significant events occurring after the close of trading in the security and changes in overall market conditions. The valuation committee employs additional fair value procedures to address issues related to equity securities that trade principally in markets outside the United States. Such securities may trade in markets that open and close at different times, reflecting time zone differences. If significant events occur after the close of a market (and before the fund’s net asset values are next determined) which affect the value of equity securities held in the fund’s portfolio, appropriate adjustments from closing market prices may be made to reflect these events. Events of this type could include, for example, earthquakes and other natural disasters or significant price changes in other markets (e.g., U.S. stock markets).

Certain short-term securities, such as variable rate demand notes or repurchase agreements involving securities fully collateralized by cash or U.S. government securities, are valued at par.

Assets and liabilities, including investment securities, denominated in currencies other than U.S. dollars are translated into U.S. dollars, prior to the next determination of the net asset value of the fund’s shares, at the exchange rates obtained from a third-party pricing vendor.

Each class of shares represents interests in the same portfolio of investments and is identical in all respects to each other class, except for differences relating to distribution, service and other charges and expenses, certain voting rights, differences relating to eligible investors, the designation of each class of shares, conversion features and exchange privileges. Expenses attributable to the fund, but not to a particular class of shares, are borne by each class pro rata based on the relative aggregate net assets of the classes. Expenses directly attributable to a class of shares are borne by that class of shares. Liabilities attributable to particular share classes, such as liabilities for repurchase of fund shares, are deducted from total assets attributable to such share classes.

Net assets so obtained for each share class are then divided by the total number of shares outstanding of that share class, and the result, rounded to the nearest cent, is the net asset value per share for that class.

Taxes and distributions

Disclaimer: Some of the following information may not apply to certain shareholders, including those holding fund shares in a tax-favored account, such as a retirement plan or education savings account. Shareholders should consult their tax advisors about the application of federal, state and local tax law in light of their particular situation.

Taxation as a regulated investment company — The fund intends to qualify each year as a “regulated investment company” under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”), so that it will not be liable for federal tax on income and capital gains distributed to shareholders. In order to qualify as a regulated investment company, and avoid being subject to federal income taxes, the fund intends to distribute substantially all of its net investment income and realized net capital gains on a fiscal year basis, and intends to comply with other tests applicable to regulated investment companies under Subchapter M.

The Code includes savings provisions allowing the fund to cure inadvertent failures of certain qualification tests required under Subchapter M. However, should the fund fail to qualify under Subchapter M, the fund would be subject to federal, and possibly state, corporate taxes on its taxable income and gains.

Amounts not distributed by the fund on a timely basis in accordance with a calendar year distribution requirement may be subject to a nondeductible 4% excise tax. Unless an applicable exception applies, to avoid the tax, the fund must distribute during each calendar year an amount equal to the sum of (a) at least 98% of its ordinary income (not taking into account any capital gains or losses) for the calendar year, (b) at least 98.2% of its capital gains in excess of its capital losses for the twelve month period ending on October 31, and (c) all ordinary income and capital gains for previous years that were not distributed during such years and on which the fund paid no U.S. federal income tax.

Dividends paid by the fund from ordinary income or from an excess of net short-term capital gain over net long-term capital loss are taxable to shareholders as ordinary income dividends. Shareholders of the fund that are individuals and meet certain holding period requirements with respect to their fund shares may be eligible for reduced tax rates on “qualified dividend income,” if any, distributed by the fund to such shareholders.

The fund may declare a capital gain distribution consisting of the excess of net realized long-term capital gains over net realized short-term capital losses. Net capital gains for a fiscal year are computed by taking into account any capital loss carryforward of the fund.

The fund may retain a portion of net capital gain for reinvestment and may elect to treat such capital gain as having been distributed to shareholders of the fund. Shareholders may receive a credit for the tax that the fund paid on such undistributed net capital gain and would increase the basis in their shares of the fund by the difference between the amount of includible gains and the tax deemed paid by the shareholder.

Distributions of net capital gain that the fund properly reports as a capital gain distribution generally will be taxable as long-term capital gain, regardless of the length of time the shares of the fund have been held by a shareholder. Any loss realized upon the redemption of shares held at the time of redemption for six months or less from the date of their purchase will be treated as a long-term capital loss to the extent of any capital gain distributions (including any undistributed amounts treated as distributed capital gains, as described above) during such six-month period.

Capital gain distributions by the fund result in a reduction in the net asset value of the fund’s shares. Investors should consider the tax implications of buying shares just prior to a capital gain distribution.

The Income Fund of America — Page 78

The price of shares purchased at that time includes the amount of the forthcoming distribution. Those purchasing just prior to a distribution will subsequently receive a partial return of their investment capital upon payment of the distribution, which will be taxable to them.

Individuals (and certain other non-corporate entities) are generally eligible for a 20% deduction with respect to taxable ordinary REIT dividends through 2025. Applicable Treasury regulations allow the fund to pass through to its shareholders such taxable ordinary REIT dividends. Accordingly, individual (and certain other non-corporate) shareholders of the fund that have received such taxable ordinary REIT dividends may be able to take advantage of this 20% deduction with respect to any such amounts passed through.

Redemptions and exchanges of fund shares — Redemptions of shares, including exchanges for shares of other American Funds, may result in federal, state and local tax consequences (gain or loss) to the shareholder.

Any loss realized on a redemption or exchange of shares of the fund will be disallowed to the extent substantially identical shares are reacquired within the 61-day period beginning 30 days before and ending 30 days after the shares are disposed of. Any loss disallowed under this rule will be added to the shareholder’s tax basis in the new shares purchased.

If a shareholder exchanges or otherwise disposes of shares of the fund within 90 days of having acquired such shares, and if, as a result of having acquired those shares, the shareholder subsequently pays a reduced or no sales charge for shares of the fund, or of a different fund acquired before January 31^st of the year following the year the shareholder exchanged or otherwise disposed of the original fund shares, the sales charge previously incurred in acquiring the fund’s shares will not be taken into account (to the extent such previous sales charges do not exceed the reduction in sales charges) for the purposes of determining the amount of gain or loss on the exchange, but will be treated as having been incurred in the acquisition of such other fund(s).

Tax consequences of investing in non-U.S. securities — Dividend and interest income received by the fund from sources outside the United States may be subject to withholding and other taxes imposed by such foreign jurisdictions. Tax conventions between certain countries and the United States, however, may reduce or eliminate these foreign taxes. Some foreign countries impose taxes on capital gains with respect to investments by foreign investors.

If more than 50% of the value of the total assets of the fund at the close of the taxable year consists of securities of foreign corporations, the fund may elect to pass through to shareholders the foreign taxes paid by the fund. If such an election is made, shareholders may claim a credit or deduction on their federal income tax returns for, and will be required to treat as part of the amounts distributed to them, their pro rata portion of qualified taxes paid by the fund to foreign countries. The application of the foreign tax credit depends upon the particular circumstances of each shareholder.

Foreign currency gains and losses, including the portion of gain or loss on the sale of debt securities attributable to fluctuations in foreign exchange rates, are generally taxable as ordinary income or loss. These gains or losses may increase or decrease the amount of dividends payable by the fund to shareholders. A fund may elect to treat gain and loss on certain foreign currency contracts as capital gain and loss instead of ordinary income or loss.

If the fund invests in stock of certain passive foreign investment companies (PFICs), the fund intends to mark-to-market these securities and recognize any gains at the end of its fiscal and excise tax years. Deductions for losses are allowable only to the extent of any previously recognized gains. Both gains and losses will be treated as ordinary income or loss, and the fund is required to distribute any

The Income Fund of America — Page 79

resulting income. If the fund is unable to identify an investment as a PFIC security and thus does not make a timely mark-to-market election, the fund may be subject to adverse tax consequences.

Tax consequences of investing in derivatives — The fund may enter into transactions involving derivatives, such as futures, swaps, options and forward contracts. Special tax rules may apply to these types of transactions that could defer losses to the fund, accelerate the fund’s income, alter the holding period of certain securities or change the classification of capital gains. These tax rules may therefore impact the amount, timing and character of fund distributions.

Discount — Certain bonds acquired by the fund, such as zero coupon bonds, may be treated as bonds that were originally issued at a discount. Original issue discount represents interest for federal income tax purposes and is generally defined as the difference between the price at which a bond was issued (or the price at which it was deemed issued for federal income tax purposes) and its stated redemption price at maturity. Original issue discount is treated for federal income tax purposes as tax exempt income earned by a fund over the term of the bond, and therefore is subject to the distribution requirements of the Code. The annual amount of income earned on such a bond by a fund generally is determined on the basis of a constant yield to maturity which takes into account the semiannual compounding of accrued interest (including original issue discount). Certain bonds acquired by the fund may also provide for contingent interest and/or principal. In such a case, rules similar to those for original issue discount bonds would require the accrual of income based on an assumed yield that may exceed the actual interest payments on the bond.

Some of the bonds may be acquired by a fund on the secondary market at a discount which exceeds the original issue discount, if any, on such bonds. This additional discount constitutes market discount for federal income tax purposes. Any gain recognized on the disposition of any bond having market discount generally will be treated as taxable ordinary income to the extent it does not exceed the accrued market discount on such bond (unless a fund elects to include market discount in income in the taxable years to which it is attributable). Realized accrued market discount on obligations that pay tax-exempt interest is nonetheless taxable. Generally, market discount accrues on a daily basis for each day the bond is held by a fund at a constant rate over the time remaining to the bond’s maturity. In the case of any debt instrument having a fixed maturity date of not more than one year from date of issue, the gain realized on disposition will be treated as short-term capital gain. Some of the bonds acquired by a fund with a fixed maturity date of one year or less from the date of their issuance may be treated as having original issue discount or, in certain cases, “acquisition discount” (generally, the excess of a bond’s stated redemption price at maturity over its acquisition price). A fund will be required to include any such original issue discount or acquisition discount in taxable ordinary income. The rate at which such acquisition discount and market discount accrues, and is thus included in a fund’s investment company taxable income, will depend upon which of the permitted accrual methods the fund elects.

Other tax considerations — After the end of each calendar year, individual shareholders holding fund shares in taxable accounts will receive a statement of the federal income tax status of all distributions. Shareholders of the fund also may be subject to state and local taxes on distributions received from the fund.

For fund shares acquired on or after January 1, 2012, the fund is required to report cost basis information for redemptions, including exchanges, to both shareholders and the IRS.

Shareholders may obtain more information about cost basis online at capitalgroup.com/costbasis.

Under the backup withholding provisions of the Code, the fund generally will be required to withhold federal income tax on all payments made to a shareholder if the shareholder either does not furnish the fund with the shareholder’s correct taxpayer identification number or fails to certify that the

The Income Fund of America — Page 80

shareholder is not subject to backup withholding. Backup withholding also applies if the IRS notifies the shareholder or the fund that the taxpayer identification number provided by the shareholder is incorrect or that the shareholder has previously failed to properly report interest or dividend income.

The foregoing discussion of U.S. federal income tax law relates solely to the application of that law to U.S. persons (i.e., U.S. citizens and legal residents and U.S. corporations, partnerships, trusts and estates). Each shareholder who is not a U.S. person should consider the U.S. and foreign tax consequences of ownership of shares of the fund, including the possibility that such a shareholder may be subject to U.S. withholding taxes.

The Income Fund of America — Page 81

Unless otherwise noted, all references in the following pages to Class A, C, T or F shares also refer to the corresponding Class 529-A, 529-C, 529-T or 529-F shares. Class 529 shareholders should also refer to the applicable program description for information on policies and services specifically relating to these accounts. Shareholders holding shares through an eligible retirement plan should contact their plan’s administrator or recordkeeper for information regarding purchases, sales and exchanges.

Class 529-E shares may be purchased only by investors participating in CollegeAmerica through an eligible employer plan. American Funds state tax-exempt funds are qualified for sale only in certain jurisdictions, and tax-exempt funds in general should not serve as retirement plan investments. In addition, the fund and the Principal Underwriter reserve the right to reject any purchase order.

Purchase minimums and maximums — All investments are subject to the purchase minimums and maximums described in the prospectus. As noted in the prospectus, purchase minimums may be waived or reduced in certain cases.

In the case of American Funds non-tax-exempt funds, the initial purchase minimum of $250 may be waived for the following account types:

· Payroll deduction retirement plan accounts (such as, but not limited to, 403(b), 401(k), SIMPLE IRA, SARSEP and deferred compensation plan accounts); and

· Employer-sponsored CollegeAmerica accounts.

The Income Fund of America — Page 83

The following account types may be established without meeting the initial purchase minimum:

· Retirement accounts that are funded with employer contributions; and

· Accounts that are funded with monies set by court decree.

The following account types may be established without meeting the initial purchase minimum, but shareholders wishing to invest in two or more funds must meet the normal initial purchase minimum of each fund:

· Accounts that are funded with (a) transfers of assets, (b) rollovers from retirement plans, (c) rollovers from 529 college savings plans or (d) required minimum distribution automatic exchanges; and

· American Funds U.S. Government Money Market Fund accounts registered in the name of clients of Capital Group Private Client Services.

Certain accounts held on the fund’s books, known as omnibus accounts, contain multiple underlying accounts that are invested in shares of the fund. These underlying accounts are maintained by entities such as financial intermediaries and are subject to the applicable initial purchase minimums as described in the prospectus and this statement of additional information. However, in the case where the entity maintaining these accounts aggregates the accounts’ purchase orders for fund shares, such accounts are not required to meet the fund’s minimum amount for subsequent purchases.

Exchanges — With the exception of Class T shares, for which rights of exchange are not generally available, you may only exchange shares without a sales charge into other American Funds, Capital Group KKR Public-Private+ Funds, or Emerging Markets Equities Fund, Inc. (collectively “Capital Group Funds”) within the same share class; however, Class A, C, T or F shares may also generally be exchanged without a sales charge for the corresponding 529 share class. Clients of Capital Group Private Client Services may exchange the shares of the fund for those of any other fund(s) managed by Capital Research and Management Company or its affiliates. Class A-2 shares of Capital Group KKR Public-Private+ Funds may not be exchanged for shares of the American Funds or Emerging Markets Equities Fund, Inc.

Notwithstanding the above, exchanges from Class A shares of American Funds U.S. Government Money Market Fund may be made to Class C shares of other American Funds for dollar cost averaging purposes.

Exchange purchases are subject to the minimum investment requirements of the fund purchased and no sales charge generally applies. However, exchanges of shares from American Funds U.S. Government Money Market Fund are subject to applicable sales charges, unless the American Funds U.S. Government Money Market Fund shares were acquired by an exchange from a fund having a sales charge, or by reinvestment or cross-reinvestment of dividends or capital gain distributions.

Exchanges of Class F shares generally may only be made through fee-based programs of investment firms that have special agreements with the fund’s distributor and certain registered investment advisors.

You may exchange shares of other classes by contacting your financial professional by calling American Funds Service Company at (800) 421-4225 or using capitalgroup.com, or faxing (see “American Funds Service Company service areas” in the prospectus for the appropriate fax numbers) the Transfer Agent. For more information, see “Shareholder account services and privileges” in this statement of additional information. These transactions have the same tax consequences as ordinary sales and purchases.

The Income Fund of America — Page 84

Shares held in employer-sponsored retirement plans may be exchanged into other Capital Group Funds by contacting your plan administrator or recordkeeper. Exchange redemptions and purchases are processed simultaneously at the share prices next determined after the exchange order is received (see “Price of shares” in this statement of additional information).

Conversion — Class C shares of the fund automatically convert to Class A shares in the month of the 8-year anniversary of the purchase date. Class 529-C shares of the fund automatically convert to Class 529-A shares in the month of the 5-year anniversary of the purchase date. The board of trustees of the fund reserves the right at any time, without shareholder approval, to amend the conversion features of the Class C and Class 529-C shares, including without limitation, providing for conversion into a different share class or for no conversion. In making its decision, the board of trustees will consider, among other things, the effect of any such amendment on shareholders.

Frequent trading of fund shares — As noted in the prospectus, certain redemptions may trigger a restriction under the fund’s “frequent trading policy.” Under this policy, systematic redemptions will not trigger a restriction and systematic purchases will not be prevented if the entity maintaining the shareholder account is able to identify the transaction as a systematic redemption or purchase. For purposes of this policy, systematic redemptions include, for example, regular periodic automatic redemptions and statement of intention escrow share redemptions. Systematic purchases include, for example, regular periodic automatic purchases and automatic reinvestments of dividends and capital gain distributions. Generally, purchases and redemptions will not be considered “systematic” unless the transaction is prescheduled for a specific date.

Potentially abusive activity — American Funds Service Company will monitor for the types of activity that could potentially be harmful to the American Funds — for example, short-term trading activity in multiple funds. When identified, American Funds Service Company will request that the shareholder discontinue the activity. If the activity continues, American Funds Service Company will freeze the shareholder account to prevent all activity other than redemptions of fund shares.

Moving between share classes

If you wish to “move” your investment between share classes (within the same fund or between different funds), we generally will process your request as an exchange of the shares you currently hold for shares in the new class or fund. Below is more information about how sales charges are handled for various scenarios.

Exchanging Class C shares for Class A or Class T shares — If you exchange Class C shares for Class A or Class T shares, you are still responsible for paying any Class C contingent deferred sales charges and applicable Class A or Class T sales charges.

Exchanging Class C shares for Class F shares — If you are part of a qualified fee-based program or approved self-directed platform and you wish to exchange your Class C shares for Class F shares to be held in the program, you are still responsible for paying any applicable Class C contingent deferred sales charges.

Exchanging Class F shares for Class A shares — You can exchange Class F shares held in a qualified fee-based program for Class A shares without paying an initial Class A sales charge if you are leaving or have left the fee-based program. Your financial intermediary can also convert Class F-1 shares to Class A shares without a sales charge if they are held in a brokerage account and they were initially transferred to the account or converted from Class C shares. You can exchange Class F shares received in a conversion from Class C shares for Class A shares at any time without paying an initial Class A sales charge if you notify American Funds Service Company of the conversion when you make your request. If you have already

The Income Fund of America — Page 85

redeemed your Class F shares, the foregoing requirements apply and you must purchase Class A shares within 90 days after redeeming your Class F shares to receive the Class A shares without paying an initial Class A sales charge.

Exchanging Class A or Class T shares for Class F shares — If you are part of a qualified fee-based program or approved self-directed platform and you wish to exchange your Class A or Class T shares for Class F shares to be held in the program, any Class A or Class T sales charges (including contingent deferred sales charges) that you paid or are payable will not be credited back to your account.

Exchanging Class A shares for Class R shares — Provided it is eligible to invest in Class R shares, a retirement plan currently invested in Class A shares may exchange its shares for Class R shares. Any Class A sales charges that the retirement plan previously paid will not be credited back to the plan’s account. No contingent deferred sales charge will be assessed as part of the share class conversion.

Moving between Class F shares — If you are part of a qualified fee-based program that offers Class F shares, you may exchange your Class F shares for any other Class F shares to be held in the program. For example, if you hold Class F-2 shares, you may exchange your shares for Class F-1 or Class F-3 shares to be held in the program.

Moving between other share classes — If you desire to move your investment between share classes and the particular scenario is not described in this statement of additional information, please contact American Funds Service Company at (800) 421-4225 for more information.

Non-reportable transactions — Automatic conversions described in the prospectus will be non-reportable for tax purposes. In addition, an exchange of shares from one share class of a fund to another share class of the same fund will be treated as a non-reportable exchange for tax purposes, provided that the exchange request is received in writing by American Funds Service Company and processed as a single transaction. However, a movement between a 529 share class and a non-529 share class of the same fund will be reportable.

The Income Fund of America — Page 86

Sales charges

Class A purchases

Purchases by certain 403(b) plans

A 403(b) plan may not invest in American Funds Class A or C shares unless such plan was invested in Class A or C shares before January 1, 2009.

Purchases by SEP plans and SIMPLE IRA plans

Participant accounts in a Simplified Employee Pension (SEP) plan or a Savings Incentive Match Plan for Employees of Small Employers IRA (SIMPLE IRA) will be aggregated at the plan level for Class A sales charge purposes if an employer adopts a prototype plan produced by Capital Client Group, Inc. or (a) the employer or plan sponsor submits all contributions for all participating employees in a single contribution transmittal or the contributions are identified as related to the same plan; (b) each transmittal is accompanied by checks or wire transfers and generally must be submitted through the transfer agent’s automated contribution system if held on the fund’s books; and (c) if the fund is expected to carry separate accounts in the name of each plan participant and (i) the employer or plan sponsor notifies the funds’ transfer agent or the intermediary holding the account that the separate accounts of all plan participants should be linked and (ii) all new participant accounts are established by submitting the appropriate documentation on behalf of each new participant. Participant accounts in a SEP or SIMPLE plan that are eligible to aggregate their assets at the plan level may not also aggregate the assets with their individual accounts.

The Income Fund of America — Page 87

Other purchases

In addition, American Funds Class A and Class 529-A shares may be offered at net asset value to companies exchanging securities with the fund through a merger, acquisition or exchange offer and to certain individuals meeting the criteria described above who invested in Class A and Class 529-A shares before Class F-2 and Class 529-F-2 shares were made available under this privilege.

Transfers to CollegeAmerica — A transfer from the Virginia Prepaid Education ProgramSM or the Virginia Education Savings TrustSM to a CollegeAmerica account will be made with no sales charge. No commission will be paid to the dealer on such a transfer. Investment dealers will be compensated solely with an annual service fee that begins to accrue immediately.

Class F-2 and Class 529-F-2 purchases

If requested, American Funds Class F-2 and Class 529-F-2 shares will be sold to:


	(1)	current or retired directors, trustees, officers and advisory board members of, and certain lawyers who provide services to the funds managed by Capital Research and Management Company, current or retired employees of The Capital Group Companies, Inc. and its affiliated companies, certain family members of the above persons, and trusts or plans primarily for such persons; and
	(2)	The Capital Group Companies, Inc. and its affiliated companies.

Once an account in Class F-2 or Class 529-F-2 is established under this privilege, additional investments can be made in Class F-2 or Class 529-F-2 for the life of the account. Depending on the financial intermediary holding your account, these privileges may be unavailable. Investors should consult their financial intermediary for further information.

Moving between accounts — American Funds investments by certain account types may be moved to other account types without incurring additional Class A sales charges. These transactions include:

· redemption proceeds from a non-retirement account (for example, a joint tenant account) used to purchase fund shares in an IRA or other individual-type retirement account;

· required minimum distributions from an IRA or other individual-type retirement account used to purchase fund shares in a non-retirement account; and

· death distributions paid to a beneficiary’s account that are used by the beneficiary to purchase fund shares in a different account.

Investors may not move investments from a Capital Bank & Trust Company SIMPLE IRA Plus to a Capital Bank & Trust Company SIMPLE IRA unless it is part of a plan transfer or to a current employer’s Capital Bank & Trust Company SIMPLE IRA plan.

Loan repayments — Repayments on loans taken from a retirement plan are not subject to sales charges if American Funds Service Company is notified of the repayment.

The Income Fund of America — Page 88

Dealer commissions and compensation — Commissions (up to 1.00%) are paid to dealers who initiate and are responsible for certain Class A share purchases not subject to initial sales charges. These purchases consist of a) purchases of $1 million or more, and b) purchases by employer-sponsored defined contribution-type retirement plans investing $1 million or more or with 100 or more eligible employees. Commissions on such investments (other than IRA rollover assets that roll over at no sales charge under the fund’s IRA rollover policy as described in the prospectus) are paid to dealers at the following rates: 1.00% on amounts of less than $10 million, .50% on amounts of at least $10 million but less than $25 million and .25% on amounts of at least $25 million. Commissions are based on cumulative investments over the life of the account with no adjustment for redemptions, transfers, or market declines. For example, if a shareholder has accumulated investments in excess of $10 million (but less than $25 million) and subsequently redeems all or a portion of the account(s), purchases following the redemption will generate a dealer commission of .50%.

A dealer concession of up to 1% may be paid by the fund under its Class A plan of distribution to reimburse the Principal Underwriter in connection with dealer and wholesaler compensation paid by it with respect to investments made with no initial sales charge.

The Income Fund of America — Page 89

Sales charge reductions and waivers

Reducing your Class A sales charge — As described in the prospectus, there are various ways to reduce your sales charge when purchasing Class A shares. Additional information about Class A sales charge reductions is provided below. Class A-2 shares of Capital Group KKR Public-Private+ Funds are not eligible for the sales charge reductions noted below.

Statement of intention — By establishing a statement of intention (the "Statement"), you enter into a nonbinding commitment to purchase eligible shares of Capital Group Funds (excluding American Funds U.S. Government Money Market Fund) over a 13-month period and receive the same sales charge (expressed as a percentage of your purchases) as if all shares had been purchased at once, unless the Statement is upgraded as described below.

The Statement period starts on the date on which your first purchase made toward satisfying the Statement is processed. Your accumulated holdings (as described in the paragraph below titled “Rights of accumulation”) eligible to be aggregated as of the day immediately before the start of the Statement period may be credited toward satisfying the Statement.

You may revise the commitment you have made in your Statement upward at any time during the Statement period. If your prior commitment has not been met by the time of the revision, the Statement period during which purchases must be made will remain unchanged. Purchases made from the date of the revision will receive the reduced sales charge, if any, resulting from the revised Statement. If your prior commitment has been met by the time of the revision, your original Statement will be considered met and a new Statement will be established.

The Statement will be considered completed if the shareholder dies within the 13-month Statement period. Commissions to dealers will not be adjusted or paid on the difference between the Statement amount and the amount actually invested before the shareholder’s death.

When a shareholder elects to use a Statement, shares equal to 5% of the dollar amount specified in the Statement may be held in escrow in the shareholder’s account out of the initial purchase (or subsequent purchases, if necessary) by the Transfer Agent. All dividends and any capital gain distributions on shares held in escrow will be credited to the shareholder’s account in shares (or paid in cash, if requested). If the intended investment is not completed within the specified Statement period the investments made during the statement period will be adjusted to reflect the difference between the sales charge actually paid and the sales charge which would have been paid if the total of such purchases had been made at a single time. Any dealers assigned to the shareholder’s account at the time a purchase was made during the Statement period will receive a corresponding commission adjustment if appropriate.

Shareholders purchasing shares at a reduced sales charge under a Statement indicate their acceptance of these terms and those in the prospectus with their first purchase.

The Statement period may be extended in cases where the fund’s distributor determines it is appropriate to do so; for example in periods when there are extenuating circumstances such as a natural disaster that may limit an individual’s ability to meet the investment required under the Statement.

The Income Fund of America — Page 90

Aggregation — Qualifying investments for aggregation include purchases of eligible classes of shares of the Capital Group Funds made by you and your “immediate family” as defined in the prospectus, if all parties are purchasing shares for their own accounts and/or:
