Investment Objective

The fund’s goal is to seek current income consistent with stability of capital and liquidity. The fund’s investment objective is not fundamental and therefore may be changed by the fund’s Board of Trustees without shareholder approval.

Fund Fees and Expenses

(2)

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. Your actual costs may be higher or lower.

Principal Investment Strategies

The fund is a money market fund that is designed to serve as a complementary product to traditional stable share price money market funds. Unlike a traditional stable share price money market fund, the fund will not use the amortized cost method of valuation or round the per share net asset value (NAV) to the nearest whole cent and does not seek to maintain a stable share price. As a result, the fund’s share price, which is its NAV, will vary and reflect the effects of unrealized appreciation and depreciation and realized losses and gains.

To pursue its goal, the fund invests in high-quality short-term money market investments issued by U.S. and foreign issuers, such as:

•

commercial paper, including asset-backed commercial paper

•

promissory notes

•

certificates of deposit and time deposits

•

variable- and floating-rate debt securities

•

bank notes and bankers’ acceptances

•

repurchase agreements

•

obligations that are issued by the U.S. government, its agencies or instrumentalities, including obligations that are not guaranteed by the U.S. Treasury, such as those issued by the

REG90254-14   00261647​

Federal National Mortgage Association (Fannie Mae) and the Federal Home Loan Mortgage Corporation (Freddie Mac) (U.S. government securities)

All of these investments will be denominated in U.S. dollars, including those that are issued by foreign issuers. 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. Certain of the fund’s securities are subject to credit or liquidity enhancements, which are designed to provide incremental levels of creditworthiness or liquidity.

The fund may engage in repurchase agreement transactions that are collateralized by cash or U.S. government securities. In addition, the fund may engage in repurchase agreement transactions that are collateralized by money market instruments, debt securities, loan participations or other securities, including equity securities and securities that are rated below investment grade or their unrated equivalents as determined by the investment adviser.

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. Some of these policies may be stricter than the federal regulations that apply to all money market funds.

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.

The investment adviser’s credit research department analyzes and monitors the securities that the fund owns or is considering buying. The 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.

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. Because the share price of the fund will fluctuate, when you sell your shares they may be worth more or less than what you originally paid for them. The fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the fund’s liquidity falls below required minimums because of market conditions or other factors. 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. 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. A sudden or unpredictable rise or decline in interest rates may cause volatility. 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.

Repurchase Agreements Risk. When the fund enters into a repurchase agreement, the fund is exposed to the risk that the other party (i.e., the counterparty) will not fulfill its contractual obligation. In a repurchase agreement, there exists the risk that, when the fund buys a security from a counterparty that agrees to repurchase the security at an agreed upon price (usually higher) and time, the counterparty will not repurchase the security. These risks are magnified to the extent that a repurchase agreement is secured by collateral other than cash and government securities, such as debt securities, equity securities and high-yield securities that are rated below investment grade (also referred to as junk bonds) (Alternative Collateral). High-yield securities that are used as Alternative Collateral are subject to greater levels of credit and liquidity risk, and are considered primarily speculative with respect to the issuer’s continuing ability to make principal and interest payments. Alternative Collateral may be subject to greater price volatility and may be more volatile or less liquid than other types of collateral, increasing the risk that the fund will be unable to recover fully in the event of a counterparty’s default.

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. Even though the fund’s investments in repurchase agreements are collateralized at all times, there is some

2Schwab Variable Share Price Money Fund | Summary Prospectus

risk to the fund if the other party should default on its obligations and the fund is delayed or prevented from recovering or disposing of the collateral. 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. 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.

Credit and Liquidity Enhancements Risk. The fund may invest in securities with credit or liquidity enhancements provided by a bank or other financial institution, and the existence and nature of such enhancements may be a significant factor in the investment adviser’s decision-making process. Generally, these enhancements are employed by the issuers of the securities to reduce credit risk and provide enhanced or back-up liquidity for a purchaser, such as the fund. Adverse developments affecting these banks and financial institutions could therefore have a negative effect on the value of the fund’s holdings. For example, a rating agency downgrade of a credit or liquidity enhancement provider may adversely affect the value of securities held by the fund. Any decline in the value of the securities held by the fund could cause the fund’s share price or yield to fall. To the extent that a portion of the fund’s underlying investments are enhanced by the same bank or financial institution, these risks may be increased.

Foreign Investment Risk. Although the fund may invest only in U.S. dollar-denominated securities, the fund’s investments in securities of foreign issuers or securities with credit or liquidity enhancements provided by foreign entities may involve certain risks that are greater than those associated with investments in securities of U.S. issuers or securities with credit or liquidity enhancements provided by U.S. entities. These include risks of adverse changes in foreign economic, political, regulatory and other conditions; the imposition of economic sanctions or other government restrictions; differing accounting, auditing, financial reporting and legal standards and practices; differing securities market structures; and higher transaction costs. These risks may negatively impact the value or liquidity of the fund’s investments, and could impair the fund’s ability to meet its investment objective or invest in accordance with its investment strategy. In addition, sovereign risk, or the risk that a government may become unwilling or unable to meet its loan obligations or guarantees, could increase the credit risk of financial institutions connected to that particular country.

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.

Liquidity Risk. Liquidity risk exists when particular investments are difficult to purchase, sell or value, especially during stressed market conditions. The market for certain investments may become illiquid due to specific adverse changes in the conditions of a particular issuer or under adverse market or economic conditions independent of the issuer. In addition, limited dealer inventories of certain securities could potentially lead to decreased liquidity. In such cases, the fund, due to limitations on investments in illiquid securities and the difficulty in readily purchasing and selling such securities at favorable times or prices, may decline in value, experience lower returns and/or be unable to achieve its desired level of exposure to a certain issuer or sector. Further, transactions in illiquid securities may entail transaction costs that are higher than those for transactions in liquid securities.

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. This could cause the fund to be unable to pay redemption proceeds within a short period of time.

Variable NAV Risk. The fund does not maintain a stable NAV per share. The value of the fund’s shares will be calculated to four decimal places and will fluctuate with changes in the values of the fund’s portfolio securities. You could lose money by investing in the fund.

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.
