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 fee 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, 529-F-2, 529-F-3 or ABLE-F-2 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:

Principal investment strategies

The fund will invest at least 99.5% of its total assets in cash, U.S. Treasury securities and other government securities guaranteed or issued by an agency or instrumentality of the U.S. government, and repurchase agreements that are fully collateralized by cash or government securities. Additionally, at least 80% of the fund’s assets will normally be invested in securities that are issued or guaranteed by the U.S. government, its agencies and instrumentalities, and repurchase agreements that are fully collateralized by government securities.

Repurchase agreements are agreements under which the fund purchases a security from a bank or broker-dealer and obtains a simultaneous commitment from the seller to repurchase the security at a specified time and price. Because the security purchased by the fund constitutes collateral for the seller’s repurchase obligation, a repurchase agreement is effectively a loan by the fund that is collateralized by the security purchased. The fund will only enter into repurchase agreements involving securities of the type (excluding any maturity limitations) in which it could otherwise invest. In practice, the fund expects to enter only into repurchase agreements that are fully collateralized by cash or U.S. government securities.

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 provide current income while preserving capital and maintaining liquidity.

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 U.S. Government Money Market Funds Average includes the fund and other funds that disclose investment objectives and/or strategies reasonably comparable to those of the fund. Prior to April 1, 2016, the fund operated as a prime money market fund and may have invested in certain types of securities that the fund is no longer permitted to hold. Consequently, the results information below may have been different if the current investment limitations had been in effect during the period prior to the fund’s conversion to a government money market fund. Past investment results are not predictive of future investment results. Prior to October 30, 2020, certain fees, such as 12b-1 fees, were not charged on Class 529-F-1 shares. If these expenses had been deducted, results would have been lower. Updated information on the fund’s investment results can be obtained by visiting capitalgroup.com.
