Prices and returns will vary, so investors may lose money. View .

Returns at net asset value (NAV) do not reflect a sales charge. If a sales charge had been deducted, the results would have been lower.

Investments are not FDIC-insured, nor are they deposits of or guaranteed by a bank or any other entity, so they may lose value.

Investors should carefully consider investment objectives, risks, charges and expenses. This and other important information is contained in the fund , which can be obtained from a financial professional and should be read carefully before investing.

The return of principal for bond portfolios and for portfolios with significant underlying bond holdings is not guaranteed. Investments are subject to the same interest rate, inflation and credit risks associated with the underlying bond holdings.

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.

Lower rated bonds are subject to greater fluctuations in value and risk of loss of income and principal than higher rated bonds.

While not directly correlated to changes in interest rates, the values of inflation-linked bonds generally fluctuate in response to changes in real interest rates and may experience greater losses than other debt securities with similar durations.

Investing outside the United States involves risks, such as currency fluctuations, periods of illiquidity and price volatility. These risks may be heightened in connection with investments in developing countries.

Investments in mortgage-related securities involve additional risks, such as prepayment risk.

Interests in Capital Group's U.S. Government Securities portfolios are not guaranteed by the U.S. government.

All Capital Group trademarks mentioned are owned by The Capital Group Companies, Inc., an affiliated company or fund. All other company and product names mentioned are the property of their respective companies.

Investment results assume all distributions are reinvested and reflect applicable fees and expenses.

Since American Funds Corporate Bond Fund's inception through July 29, 2016, certain fees, such as 12b-1 fees, were not charged on Class A shares. If these expenses had been deducted, results would have been lower.
