Investment Objective

​

The fund seeks long-term capital growth.

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.

​

(1)

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 fund to 0.86% for so long as the investment adviser serves as the adviser to the fund. This 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.

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 62% of the average value of its portfolio.

Principal Investment Strategies

​

To pursue its investment objective, the fund invests primarily in the stocks of publicly traded companies located in developed market countries excluding the United States, however, the fund may also invest in stocks issued by companies located in emerging markets. Developed market countries include, but are not limited to, Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Hong Kong, Ireland, Italy, Japan, Netherlands, New Zealand, Norway, Singapore, Spain, Sweden, Switzerland, and the United Kingdom. The fund considers any country that is not a developed market country to be an emerging market country.

Under normal circumstances, the fund invests at least 80% of its net assets (including, for this purpose, any borrowings for investment purposes) in equity securities. The fund will notify its shareholders at least 60 days before changing this policy. The fund typically invests a majority of its assets in the stocks of large-cap and mid-cap companies, but may invest a portion of its assets in small-cap companies. In addition, the portfolio managers seek to allocate the fund's investments across different countries and geographic regions in an effort to manage the economic and socio-political risks

associated with investing in a single country or limited number of countries. The fund generally does not intend to hedge its exposure to foreign currencies.

The fund seeks to assemble a portfolio with long-term performance that will exceed that of the MSCI EAFE® Index (the Index). The Index includes over 900 securities listed on the stock exchanges of certain developed market countries in Europe, Australia, Asia, and the Far East. The fund approaches risk management from the perspective of the Index. The portfolio managers seek to keep the fund's volatility similar to that of the Index.

The fund uses a portfolio optimization process to assist in constructing the portfolio. The portfolio managers use the portfolio optimization process to seek to build a portfolio they believe will provide the optimal balance between risk and expected return, subject to parameters such as the number of stocks desired in the portfolio, the level of portfolio turnover, country and sector diversification, and volatility considerations.

The fund actively selects portfolio securities. To aid its stock selection, the fund uses Schwab Equity Ratings International®, a model that ranks stocks of foreign companies headquartered and trading in certain foreign countries. The stocks are ranked based on factors that Schwab believes to be indicative of stocks' performance potential. The fund may also use additional research as a component of its overall stock selection process. This research may incorporate the analysis of factors including, but not limited to, valuation, balance sheet strength, future earnings power and trading activity to identify companies expected to outperform the broader equity market. Generally, when constructing the portfolio, the portfolio managers invest in stocks that are highly rated by Schwab Equity Ratings International. As part of the portfolio construction process, the portfolio managers may also purchase lower-rated stocks or stocks that are not rated by Schwab Equity Ratings International. This investment approach under normal conditions will result in a portfolio that maintains an overall weighting toward highly-rated stocks. For more information about Schwab Equity Ratings International, please see the "More About Schwab's Research" section in the prospectus.

The fund may invest in derivatives, principally futures contracts, primarily to seek returns on the fund's otherwise uninvested cash assets. A futures contract is a contract to buy or sell a specific financial instrument at a specified price at a specific future time. By using these instruments, the fund potentially can offset the impact on its performance of keeping some assets in cash. The fund may invest in exchange-traded funds (ETFs) and stocks of real estate investment trusts (REITs). The fund may also invest in depository receipts evidencing ownership of shares of foreign issuers, including American Depositary Receipts (ADRs), Global Depositary Receipts (GDRs), and European Depositary Receipts (EDRs). The fund also may lend portfolio securities to earn additional income. Any income realized through securities lending may help fund performance.

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. The fund also may

invest in these types of securities or hold cash while looking for suitable investment opportunities. When the fund engages in such activities, it may not achieve its investment objective.

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. 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.

Management Risk. The fund's investment adviser makes investment decisions for the fund using a strategy based largely on historical information. There is no guarantee that a strategy based on historical information will produce the desired results in the future. In addition, the portfolio optimization process used by the fund to assist in constructing the fund's portfolio does not assure successful investment. Securities selected with the assistance of the investment process may be negatively impacted by factors or events not foreseen in developing the process. The portfolio optimization process and Schwab Equity Ratings International may not adequately take into account certain factors or may rely on inaccurate data inputs, may contain design flaws or faulty assumptions, and may rely on incomplete or inaccurate data inputs. As a result, the fund may have a lower return than if it were managed using another process or strategy.

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.

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. Foreign securities also include ADRs, GDRs and EDRs, which may be less liquid than the underlying shares in their primary trading market, and GDRs, in particular, many of which are issued by companies in emerging markets, may be more volatile. To the extent the fund's investments in a single country or a limited number of countries represent a large percentage of the fund's assets, the fund's performance may be adversely affected by the economic, political, regulatory and social conditions in those countries, and the fund's price may be more volatile than the price of a fund that is geographically diversified.

Emerging Markets Risk. Emerging market countries may be more likely to experience political turmoil or rapid changes in market or economic conditions than more developed countries. Emerging market countries often have less uniformity in accounting, auditing, financial reporting and recordkeeping requirements and greater risk associated with the custody of securities. In addition, the financial stability of issuers (including governments) in emerging market countries may be more precarious than in developed countries. As a result, there may be an increased risk of illiquidity and price volatility associated with the fund's investments in emerging market countries, which may be magnified by currency fluctuations relative to the U.S. dollar, and, at times, it may be difficult to value such investments.

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 its volatility and 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.

ETF Risk. When the fund invests in an ETF, it will bear a proportionate share of the ETF's expenses. In addition, lack of liquidity in the market for an ETF's shares can result in its value being more volatile than the underlying portfolio of securities.

Securities Lending Risk. Securities lending involves the risk of loss of rights in, or delay in recovery of, the loaned securities if the borrower fails to return the security loaned or becomes insolvent.

REITs Risk. The fund's investments in REITs will be subject to the risks associated with the direct ownership of real estate, including fluctuations in the value of underlying properties, defaults by borrowers or tenants, changes in interest rates and risks related to general or local economic conditions. REITs are also subject to certain additional risks, for example, REITs are dependent upon specialized management skills and cash flows, and may have their investments in relatively few properties, a small geographic area or a single property type. Failure of a company to qualify as a REIT

under federal tax law may have adverse consequences on the fund. In addition, REITs have their own expenses, and the fund will bear a proportionate share of those expenses.

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.

Portfolio Turnover Risk. The fund buys and sells portfolio securities actively. This may cause the fund's portfolio turnover rate and transaction costs to rise, which may lower the fund's performance and may increase the likelihood of capital gains distributions.
