American Funds Inflation Linked Bond Fund® Summary prospectus February 1, 2020 (as supplemented June 30, 2020)

Beginning January 1, 2021, as permitted by regulations adopted by the U.S. Securities and Exchange Commission, we intend to no longer mail paper copies of the fund’s shareholder reports, unless specifically requested from American Funds or your financial intermediary, such as a broker-dealer or bank. Instead, the reports will be made available on the Capital Group website (capitalgroup.com); you will be notified by mail and provided with a website link to access the report each time a report is posted. If you have already elected to receive shareholder reports electronically, you will not be affected by this change and do not need to take any action. If you prefer to receive shareholder reports and other communications electronically, you may update your mailing preferences with your financial intermediary, or enroll in e-delivery at capitalgroup.com (for accounts held directly with the fund).

You may elect to receive paper copies of all future reports free of charge. If you invest through a financial intermediary, you may contact your financial intermediary to request that you continue to receive paper copies of your shareholder reports. If you invest directly with the fund, you may inform American Funds that you wish to continue receiving paper copies of your shareholder reports by contacting us at (800) 421-4225. Your election to receive paper reports will apply to all funds held with American Funds or through your financial intermediary.

Investment objective The fund’s investment objective is to provide inflation protection and income consistent with investment in inflation-linked securities.

Fees and expenses of the fund This table describes the fees and expenses that you may pay if you buy and hold shares of the fund. In addition to the fees and expenses described below, you may also be required to pay brokerage commissions on purchases and sales of Class F-2, F-3 or 529-F-1 shares of the fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $500,000 in American Funds. More information about these and other discounts is available from your financial professional, in the “Sales charge reductions and waivers” sections on page 31 of the prospectus and on page 76 of the fund’s statement of additional information, and in the sales charge waiver appendix to this prospectus.

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

The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the fund’s operating expenses remain the same. The example reflects the fee waiver described above through the expiration date of such waiver and total annual fund operating expenses thereafter. You may be required to pay brokerage commissions on your purchases and sales of Class F-2, F-3 or 529-F-1 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 78% of the average value of its portfolio.

Principal investment strategies The fund seeks to provide inflation protection and income by investing primarily in inflation-linked securities. Normally, at least 80% of the fund’s assets will be invested in inflation-linked bonds issued by U.S. and non-U.S. governments, their agencies or instrumentalities, and corporations. Inflation-linked bonds are structured to protect against inflation by linking the bond’s principal and interest payments to an inflation index so that principal and interest adjust to reflect changes in the index. For example, U.S. Treasury Inflation-Protected Securities (TIPS) are linked to the Consumer Price Index for Urban Consumers (CPURNSA). Other sovereign governments and corporations also issue inflation-linked securities that are tied to their own local consumer price index or the CPURNSA.

The fund will invest at least 80% of its assets in securities guaranteed or sponsored by the U.S. government without regard to the quality rating assigned to the U.S. government by a Nationally Recognized Statistical Rating Organization (NRSRO). To the extent the fund invests in other debt securities, the fund will invest in debt securities with quality ratings of Baa3 or better or BBB- or better by NRSROs designated by the fund’s investment adviser or in debt securities that are unrated but determined to be of equivalent quality by the fund’s investment adviser. The fund may invest in debt securities with a wide range of maturities.

The fund may also invest in certain derivative instruments, such as futures contracts and swaps. A derivative is a financial contract, the value of which is based on the value of an underlying financial asset (such as a stock, bond or currency), a reference rate or a market index. The fund may invest in a derivative only if, in the opinion of the investment adviser, the expected risks and rewards of the proposed investment are consistent with the investment objective and strategies of the fund as disclosed in this prospectus and in the fund’s statement of additional information.

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.

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 priced securities that, in its opinion, represent good, long-term investment opportunities. Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities.

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 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;

American Funds Inflation Linked Bond Fund / Summary prospectus     3

overall market changes; local, regional or global political, social or economic instability; governmental, governmental agency or central bank responses to economic conditions; 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) and other circumstances in one country or region 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.

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 related to the issuer, 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.

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 changing interest rates and by changes in the effective maturities and credit ratings of these securities.

Rising interest rates will generally cause the prices of bonds and other debt securities to fall. A general rise 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 failing to recoup the full amount of its initial investment and 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. 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 seeking to assess credit and default risks.

Investing in inflation-linked bonds — The values of inflation-linked bonds generally fluctuate in response to changes in real interest rates — i.e., rates of interest after factoring in inflation. A rise in real interest rates may cause the prices of inflation-linked securities to fall, while a decline in real interest rates may cause the prices to increase. Inflation-linked bonds may experience greater losses than other debt securities with

4     American Funds Inflation Linked Bond Fund / Summary prospectus

similar durations when real interest rates rise faster than nominal interest rates. There can be no assurance that the value of an inflation-linked security will be directly correlated to changes in interest rates; for example, if interest rates rise for reasons other than inflation, the increase may not be reflected in the security’s inflation measure.

Investing in inflation-linked bonds may also reduce the fund’s distributable income during periods of deflation. If prices for goods and services decline throughout the economy, the principal and income on inflation-linked securities may decline and result in losses to the fund.

Investing in securities backed by the U.S. government — Securities backed by the U.S. Treasury or the full faith and credit of the U.S. government are guaranteed only as to the timely payment of interest and principal when held to maturity. Accordingly, the current market values for these securities will fluctuate with changes in interest rates and the credit rating of the U.S. government. Securities issued by government-sponsored entities and federal agencies and instrumentalities that are not backed by the full faith and credit of the U.S. government are neither issued nor guaranteed by the U.S. government.

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, 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 may be forced to sell at a loss.

Investing in derivatives — The use of derivatives involves a variety of risks, which may be different from, or greater than, the risks associated with investing in traditional securities, such as stocks and bonds. Changes in the value of a derivative may not correlate perfectly with, and may be more sensitive to market events than, the underlying asset, rate or index, and a derivative instrument may expose the fund to losses in excess of its initial investment. Derivatives may be difficult to value, difficult for the fund to buy or sell at an opportune time or price and difficult, or even impossible, to terminate or otherwise offset. The fund’s use of derivatives may result in losses to the fund, and investing in derivatives may reduce the fund’s returns and increase the fund’s price volatility. The fund’s counterparty to a derivative transaction (including, if applicable, the fund’s clearing broker, the derivatives exchange or the clearinghouse) may be unable or unwilling to honor its financial obligations in respect of the transaction. In certain cases, the fund may be hindered or delayed in exercising remedies against or closing out derivative instruments with a counterparty, which may result in additional losses.

Investing outside the United States — Securities of issuers domiciled outside the United States, or with significant operations or revenues 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 operate or generate revenue. 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 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 accounting practices and different regulatory, legal and reporting 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. 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 results The following bar chart shows how the fund’s investment results have varied from year to year, and the following table shows how the fund’s average annual total returns for various periods compare with a broad measure of securities market results and other applicable measures of market results. This information provides some indication of the risks of investing in the fund. The Lipper Inflation-Protected Bond Funds Average includes other funds that disclose investment objectives and/or strategies reasonably comparable to those of the fund.
