Fund Fees and Expenses This table describes the fees and expenses you may pay if you buy, hold and sell shares of the fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below. Shareholder Fees (fees paid directly from your investment) 0 Annual Fund Operating Expenses (expenses that you pay each year as a % of the value of your investment) 0.0062 0 0.0012 0.0074 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. Your actual costs may be higher or lower. Expenses on a $10,000 Investment 76 237 411 918 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 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 the annual fund operating expenses or in the example, affect the fund’s performance. During the most recent fiscal year, the fund’s portfolio turnover rate was 39% of the average value of its portfolio. 0.39 Principal Investment Strategies Under normal circumstances, the fund invests at least 80% of its net assets (including, for this purpose, any borrowing for investment purposes) in large cap growth equity securities of U.S. companies. For purposes of the Fund’s 80% policy, large cap growth equity securities are equity securities that (i) have a market capitalization of at least $3 billion at the time of investment; and (ii) are included in the Russell 1000® Growth Index, the fund’s comparative index. In addition, up to 20% of the fund’s net assets may be invested in foreign equity securities. Investments in equity securities include common stock and preferred stock. The fund may, but is not required to, use derivative instruments for risk management purposes or as part of the fund’s investment strategies.Schwab Asset Management allocates portions of the fund’s assets among subadvisers, who then manage their respective portions under the general supervision of Schwab Asset Management. In choosing the subadvisers and their allocations, Schwab Asset Management considers a number of factors, including economic trends, and its own outlook for a given investment style category that offers the greatest potential for growth, and the subadvisers’ performance in various market conditions. In addition to monitoring and coordinating the subadvisers, Schwab Asset Management also manages the cash portion of the fund. Schwab Asset Management may also directly manage portions of the fund during transitions between subadvisers.Each subadviser uses its own securities selection process and has discretion to select portfolio securities for its allocation of the fund’s assets. At the same time, each subadviser invests with a specific investment style (e.g., U.S. large-cap growth) under the general supervision of Schwab Asset Management. Schwab Asset Management has developed parameters for each subadviser based on Schwab Asset Management’s assessment of the subadviser’s investment style and expertise. Schwab Asset Management assigns specific parameters in an attempt to capitalize on the strengths of each subadviser and to combine their investment activities in a complementary fashion.In deciding whether an investment is tied to the U.S., each subadviser considers a number of factors including whether the investment is issued or guaranteed by the U.S. government or any of its agencies; the investment has its primary trading market in the U.S.; the issuer is organized under the laws of, derives at least 50% of its revenues from, or has at least 50% of its assets in, the U.S.; the investment is included in an index representative of the U.S.; and the investment is exposed to the economic fortunes and risks of the U.S.For temporary defensive purposes during unusual economic or market conditions or for liquidity purposes, the fund may invest up to 100% of its assets in cash, money market instruments, repurchase agreements and other short-term obligations. When the fund engages in such activities, it may not achieve its investment objective. Under normal circumstances, the fund invests at least 80% of its net assets (including, for this purpose, any borrowing for investment purposes) in large cap growth equity securities of U.S. companies. For purposes of the Fund’s 80% policy, large cap growth equity securities are equity securities that (i) have a market capitalization of at least $3 billion at the time of investment; and (ii) are included in the Russell 1000® Growth Index, the fund’s comparative index. <div style="border-bottom:0.75pt; border-bottom-style:solid; border-bottom-color:#00A0DD; margin-bottom:12pt; padding:0pt 0pt 1pt 0pt;"><div style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; color:#00A0DD; font-weight:bold;">Principal Risks</div></div>The fund is subject to risks, any of which could cause an investor to lose money. The fund’s principal risks include: The fund is subject to risks, any of which could cause an investor to lose money. 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, tariffs, 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. 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. Multi-Manager Risk — Each subadviser makes investment decisions independently, and it is possible that the investment styles of subadvisers may not complement one another. As a result, the fund’s exposure to a given stock, industry or investment style could unintentionally be smaller or larger than if the fund had a single subadviser. Management Risk — As with all actively managed funds, the fund is subject to the risk that the subadvisers 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 subadvisers apply their 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. Equity Risk — The prices of equity securities rise and fall daily. These price movements may result from factors affecting individual companies, industries or the securities market as a whole. In addition, equity markets tend to move in cycles, which may cause stock prices to fall over short or extended periods of time. Market Capitalization Risk — Securities issued by companies of different market capitalizations tend to go in and out of favor based on market and economic conditions. During a period when securities of a particular market capitalization fall behind other types of investments, the fund’s performance could be impacted. Large-Cap Company Risk — Large-cap companies are generally more mature and the securities issued by these companies may not be able to reach the same levels of growth as the securities issued by small- or mid-cap companies. Growth Investing Risk — Growth stocks can be volatile. Growth companies usually invest a high portion of earnings in their businesses and may lack the dividends of value stocks that can cushion stock prices in a falling market. The prices of growth stocks are based largely on projections of the issuer’s future earnings and revenues. If a company’s earnings or revenues fall short of expectations, its stock price may fall dramatically. Growth stocks may also be more expensive relative to their earnings or assets compared to value or other stocks. Foreign Investment Risk — The fund’s investments in securities of foreign issuers involve certain risks that may be greater than those associated with investments in securities of U.S. issuers. These include risks of adverse changes in foreign economic, political, regulatory and other conditions; changes in currency exchange rates or exchange control regulations (including limitations on currency movements and exchanges); 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. There is a risk that investments in securities denominated in, and/or receiving revenues in, foreign currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency hedged, resulting in the dollar value of the fund’s investment being adversely affected. Foreign securities also include American Depositary Receipts (ADRs), Global Depositary Receipts (GDRs) and European Depositary Receipts (EDRs) which may be less liquid than the underlying shares in their primary trading market and GDRs, many of which are issued by companies in emerging markets, may be more volatile. These risks may be heightened in connection with investments in emerging markets or securities of issuers that conduct their business in emerging markets. Derivatives Risk — The fund’s use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. The fund’s use of derivatives could reduce the fund’s performance, increase the fund’s volatility, and could cause the fund to lose more than the initial amount invested. In addition, investments in derivatives may involve leverage, which means a small percentage of assets invested in derivatives can have a disproportionately large impact on the fund. Leverage Risk — Certain fund transactions, such as derivatives transactions, may give rise to a form of leverage and may expose the fund to greater risk. Leverage tends to magnify the effect of any decrease or increase in the value of the fund’s portfolio securities, which means even a small amount of leverage can have a disproportionately large impact on the fund. Liquidity Risk — The fund may be unable to sell certain securities, such as illiquid securities, readily at a favorable time or price, or the fund may have to sell them at a loss. Performance The bar chart below 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 compared to that of one or more indices. The S&P 500® Index serves as the fund’s regulatory index and provides a broad measure of market performance. The Russell 1000 Growth Index is the fund’s additional index and is more representative of the fund’s investment universe than the regulatory index.
