New Notice Regarding Shareholder Report Delivery Options

Beginning on January 1, 2021, paper copies of a fund’s shareholder reports will no longer be sent by mail, unless you specifically request paper copies of the reports from a fund or from your financial intermediary (such as a bank or broker-dealer). Instead, the reports will be made available on a fund’s website www.schwabfunds.com/schwabfunds_prospectus, and you will be notified by mail each time a report is posted and the mailing will provide a website link to access the report. You will continue to receive other fund regulatory documents (such as prospectuses or supplements) in paper unless you have elected to receive all fund documents electronically.

If you would like to continue to receive a fund’s future shareholder reports in paper free of charge after January 1, 2021, you can make that request:

• If you invest through Charles Schwab & Co, Inc. (broker-dealer), by calling 1-866-345-5954 and using the unique identifier attached to this mailing;

• If you invest through another financial intermediary (such as a bank or broker-dealer) by contacting them directly; or

• If owned directly through a fund by calling 1-800-407-0256.

If you already receive shareholder reports and other fund documents electronically, you will not be affected by this change and you need not take any action.

Before you invest, you may want to review the fund’s prospectus, which contains more information about the fund and its risks. You can find the fund’s prospectus, Statement of Additional Information (SAI), reports to shareholders and other information about the fund online at www.schwabfunds.com/schwabfunds_prospectus. You can also obtain this information at no cost by calling 1-866-414-6349 or by sending an email request to orders@mysummaryprospectus.com. If you purchase or hold fund shares through a financial intermediary, the fund’s prospectus, SAI, reports to shareholders and other information about the fund are available from your financial intermediary.

The fund’s prospectus and SAI, both dated September 24, 2020, include a more detailed discussion of fund investment policies and the risks associated with various fund investments. The prospectus and SAI are incorporated by reference into the summary prospectus, making them legally a part of the summary prospectus.

Investment Objective

The fund’s goal is to seek the highest current income that is consistent with stability of capital and liquidity.

Fund Fees and Expenses

This table describes the fees and expenses you may pay if you buy and hold shares of the fund. This table does not reflect any brokerage fees or commissions you may incur when buying or selling fund shares.

The investment adviser and its affiliates have agreed to limit the total annual fund operating expenses (excluding interest, taxes and certain non-routine expenses) of the Ultra Shares to 0.19% for so long as the investment adviser serves as the adviser to the fund (contractual expense limitation agreement). This contractual expense limitation agreement may only be amended or terminated with the approval of the fund’s Board of Trustees.

Example

This example is intended to help you compare the cost of investing in the fund with the cost of investing in other 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 time 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 figures are based on total annual fund operating expenses after any expense reduction. The example does not reflect any brokerage fees or commissions you may incur when buying or selling fund shares. Your actual costs may be higher or lower.

Principal Investment Strategies

To pursue its goal, the fund typically invests in securities backed by the full faith and credit of the U.S. government. The fund intends to operate as a government money market fund under the regulations governing money market funds. The fund will invest at least 99.5% of its total assets in cash and/or government securities (including bills and notes); under normal circumstances, at least 80% of the fund’s net assets (including, for this purpose, any borrowings for investment purposes) will be invested solely in U.S. Treasury securities (excluding cash). With respect to the 80% policy, the fund will notify its shareholders at least 60 days before changing the policy. The full faith and credit backing is the strongest backing offered by the U.S. government, and traditionally is considered by investors to be the highest degree of safety as far as the payment of principal and interest.

Based on the fund manager’s view of market conditions for U.S. Treasury securities, the fund may invest up to 20% of its net assets in: (i) obligations that are issued by the U.S. government, its agencies or instrumentalities, including obligations that are not fully guaranteed by the U.S. Treasury, such as those issued by the Federal National Mortgage Association (Fannie Mae), the Federal Home Loan Mortgage Corporation (Freddie Mac) and the Federal Home Loan Banks; and (ii) obligations that are issued by private issuers that are guaranteed as to principal or interest by the U.S. government, its agencies or instrumentalities. Obligations that are issued by private issuers that are guaranteed as to principal or interest by the U.S. government, its agencies or instrumentalities are considered U.S. government securities under the rules that govern money market funds.

In choosing securities, the fund’s manager seeks to maximize current income within the limits of the fund’s investment objective and credit, maturity and diversification policies. By investing primarily in full faith and credit U.S. government investments, the fund seeks to provide maximum safety as to its assets. The fund is distinct from certain other types of government money market funds in that it does not invest in repurchase agreements. The portfolio manager may adjust the fund’s holdings or its average maturity based on actual or anticipated changes in credit quality or market dynamics, such as interest rates. To preserve its investors’ capital, the fund seeks to maintain a stable $1.00 share price.

Because the income from U.S. Treasury securities is exempt from state and local income taxes, the fund generally expects that the majority of the dividends it pays will be exempt from those taxes as well. (Dividends still will be subject to federal income tax.) However, the fund may invest up to 20% of its net assets in non-U.S. Treasury investments that are not exempt from state and local income taxes. Further, during unusual market conditions, the fund may invest a greater portion of its assets in investments that are not exempt from state and local income taxes as a temporary defensive measure. When the fund engages in such activities, it may not achieve its investment goal.

For temporary defensive purposes during unusual market conditions, the fund may invest up to 100% of its assets in cash, cash equivalents or other high quality short-term investments.

As a government money market fund, the fund’s Board of Trustees (the Board) has determined not to subject the fund to a liquidity fee and/or a redemption gate on fund redemptions. Please note that the Board has reserved its ability to change this determination with respect to liquidity fees and/or redemption gates, but only after providing appropriate prior notice to shareholders.

Principal Risks

The fund is subject to risks, any of which could cause an investor to lose money. The fund’s principal risks include:

Market Risk. Financial markets rise and fall in response to a variety of factors, sometimes rapidly and unpredictably. Markets may be impacted by economic, political, regulatory and other conditions, including economic sanctions and other government actions. In addition, the occurrence of global events, such as war, terrorism, environmental disasters, natural disasters and epidemics, may also negatively affect the financial markets. These events could reduce consumer demand or economic output; result in market closures, low or negative interest rates, travel restrictions or quarantines; and significantly adversely impact the economy. Governmental and quasi-governmental authorities and regulators throughout the world have in the past often responded to serious economic disruptions with a variety of significant fiscal and monetary policy changes which could have an unexpected impact on financial markets and the fund’s investments. As with any investment whose performance is tied to these markets, the value of an investment in the fund will fluctuate, which means that an investor could lose money over short or long periods.

Investment Risk. You could lose money by investing in the fund. Although the fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. An investment in the fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The fund’s sponsor has no legal obligation to provide financial support to the fund, and you should not expect that the sponsor will provide financial support to the fund at any time.

Interest Rate Risk. Interest rates rise and fall over time. As with any investment whose yield reflects current interest rates, the fund’s yield will change over time. During periods when interest rates are low or there are negative interest rates, the fund’s yield (and total return) also could be low or even negative. In addition, the fund may be unable to pay expenses out of fund assets or maintain a stable $1.00 share price. Also, a change in a central bank’s monetary policy or economic conditions may result in a change in interest rates, which could have sudden and unpredictable effects on the markets. Volatility in the market may decrease liquidity in the money market securities markets, making it more difficult for the fund to sell its money market investments at a time when the investment adviser might wish to sell such investments. Decreased market liquidity also may make it more difficult to value some or all of the fund’s money market securities holdings.

Stable Net Asset Value Risk. If the fund or another money market fund fails to maintain a stable net asset value (or such perception exists in the market place), the fund could experience increased redemptions, which may adversely impact the fund’s share price.

  Schwab U.S. Treasury Money Fund | Summary Prospectus2

The fund is permitted, among other things, to reduce or withhold any income and/or gains generated from its portfolio to maintain a stable $1.00 share price.

Credit Risk. A decline in the credit quality of an issuer, guarantor or liquidity provider of a portfolio investment or a counterparty could cause the fund to lose money or underperform. The fund could lose money if, due to a decline in credit quality, the issuer, guarantor or liquidity provider of a portfolio investment or a counterparty fails to make, or is perceived as being unable or unwilling to make, timely principal or interest payments or otherwise honor its obligations. The credit quality of the fund’s portfolio holdings can change rapidly in certain market environments and any downgrade or default on the part of a single portfolio investment could cause the fund’s share price or yield to fall.

Certain U.S. government securities that the fund invests in are not backed by the full faith and credit of the U.S. government, which means they are neither issued nor guaranteed by the U.S. Treasury. Although maintained in conservatorship by the Federal Housing Finance Agency (FHFA) since September 2008, Fannie Mae and Freddie Mac maintain only lines of credit with the U.S. Treasury. Additionally, the FHFA recently announced plans to begin removing Fannie Mae and Freddie Mac from conservatorship. The Federal Home Loan Banks maintain limited access to credit lines from the U.S. Treasury. Other securities, such as obligations issued by the Federal Farm Credit Banks Funding Corporation, are supported solely by the credit of the issuer. There can be no assurance that the U.S. government will provide financial support to securities of its agencies and instrumentalities if it is not obligated to do so under law. Also, any government guarantees on securities the fund owns do not extend to the shares of the fund itself.

Management Risk. Any actively managed mutual fund is subject to the risk that its investment adviser will select investments or allocate assets in a manner that could cause the fund to underperform or otherwise not meet its investment objective. The fund’s investment adviser applies its own investment techniques and risk analyses in making investment decisions for the fund, but there can be no guarantee that they will produce the desired results. The investment adviser’s maturity decisions will also affect the fund’s yield, and potentially could affect its share price. To the extent that the investment adviser anticipates interest rate trends imprecisely, the fund’s yield at times could lag the yields of other money market funds.

Redemption Risk. The fund may experience periods of heavy redemptions that could cause the fund to liquidate its assets at inopportune times or at a loss or depressed value, particularly during periods of declining or illiquid markets. Redemptions by a few large investors in the fund may have a significant adverse effect on the fund’s ability to maintain a stable $1.00 share price. In the event any money market fund fails to maintain a stable net asset value, other money market funds, including the fund, could face a market-wide risk of increased redemption pressures, potentially jeopardizing the stability of their $1.00 share prices.

Money Market Fund Risk. The fund is not designed to offer capital appreciation. In exchange for their emphasis on stability and

liquidity, money market investments may offer lower long-term performance than stock or bond investments.

Performance

The bar chart below shows the fund’s Investor Shares investment results for the prior calendar year, and the following table shows the fund’s Investor Shares average annual total returns for various periods. This information provides some indication of the risks of investing in the fund. All figures assume distributions were reinvested. No performance is shown for the fund’s Ultra Shares because the Ultra Shares had not commenced operations prior to the date of this prospectus. The Investor Shares and the Ultra Shares of the fund would have substantially similar performance because they invest in the same portfolio of securities and the annual returns would differ only to the extent that the Ultra Shares has lower expenses. Keep in mind that future performance may differ from past performance.

Payments to Financial Intermediaries

If you purchase shares of the fund through a broker-dealer or other financial intermediary (such as a bank), the fund and its related companies may pay the intermediary for the sale of fund shares and related services.

Ask your salesperson or visit your financial intermediary’s website for more information.
