SCHX Schwab US Large Cap

Principal Investment Strategies

To pursue its goal, the fund generally invests in stocks that are included in the FTSE Developed ex US Index^†. The index is comprised of large and mid capitalization companies in developed countries outside the United States, as defined by the index provider. The index defines the large and mid capitalization universe as approximately the top 90% of the eligible universe. As of August 31, 2019, the index was composed of 1,553 stocks in 24 developed market countries.

It is the fund’s policy that under normal circumstances it will invest at least 90% of its net assets (including, for this purposes, any borrowings for investment purposes) in these stocks, including depositary receipts representing securities of the index; such depositary receipts may be in the form of American Depositary Receipts (ADRs), Global Depositary Receipts (GDRs) and European Depositary Receipts (EDRs). The fund will notify its shareholders at least 60 days before changing this policy. The fund may sell securities that are represented in the index in anticipation of their removal from the index, or buy securities that are not yet represented in the index in anticipation of their addition to the index.

Under normal circumstances, the fund may invest up to 10% of its net assets in securities not included in the index. The principal types of these investments include those that the investment adviser believes will help the fund track the index, such as investments in (a) securities that are not represented in the index but the investment adviser anticipates will be added to the index or as necessary to reflect various corporate actions (such as mergers and spin-offs); (b) other investment companies; and (c) derivatives, principally futures contracts. The fund may use futures contracts and other derivatives primarily to seek returns on the fund’s otherwise uninvested cash assets to help it better track the index. The fund may also invest in cash and cash equivalents, including money market funds, and may lend its securities to minimize the difference in performance that naturally exists between an index fund and its corresponding index. The fund does not hedge its exposure to foreign currencies.

Because it may not be possible or practicable to purchase all of the stocks in the index, the investment adviser seeks to track the total return of the index by using sampling techniques. Sampling techniques involve investing in a limited number of index securities which, when taken together, are expected to perform similarly to the index as a whole. These techniques are based on a variety of factors, including performance attributes, tax considerations, country weightings, capitalization, industry factors, risk factors and other characteristics. The fund generally expects that its portfolio will hold less than the total number of securities in the index, but reserves the right to hold as many securities as it believes necessary to achieve the fund’s investment objective.

The fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry, group of industries or sector to approximately the same extent that the index is so concentrated.

The investment adviser seeks to achieve, over time, a correlation between the fund’s performance and that of the index, before fees and expenses, of 95% or better. However, there can be no guarantee that the fund will achieve a high degree of correlation with the index. A number of factors may affect the fund’s ability to achieve a high correlation with the index, including the degree to which the fund utilizes a sampling technique (or otherwise gives a different weighting to a security than the index does). The correlation between the performance of the fund and the index may also diverge due to transaction costs, asset valuations, corporate actions (such as mergers and spin-offs), timing variances, and differences between the fund’s portfolio and the index resulting from legal restrictions (such as diversification requirements) that apply to the fund but not to the index.

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. 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 Style Risk. The fund is an index fund. Therefore, the fund follows the securities included in the index during upturns as well as downturns. Because of its indexing strategy, the fund does not take steps to reduce market exposure or to lessen the effects of a declining market. In addition, because of the fund’s expenses, the fund’s performance may be below that of the index.

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.

Mid-Cap Company Risk. Mid-cap companies may be more vulnerable to adverse business or economic events than larger,

more established companies and the value of securities issued by these companies may move sharply.

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, 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.

Sampling Index Tracking Risk. The fund may not fully replicate the index and may hold securities not included in the index. As a result, the fund is subject to the risk that the investment adviser’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results. Because the fund utilizes a sampling approach it may not track the return of the index as well as it would if the fund purchased all of the securities in the index.

Tracking Error Risk. As an index fund, the fund seeks to track the performance of the index, although it may not be successful in doing so. The divergence between the performance of the fund and the index, positive or negative, is called “tracking error.” Tracking error can be caused by many factors and it may be significant.

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.

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.

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.

Concentration Risk. To the extent that the fund’s or the index’s portfolio is concentrated in the securities of issuers in a particular market, industry, group of industries, sector, country or asset class, the fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more vulnerable to adverse economic, market, political or regulatory occurrences affecting that market, industry, group of industries, sector, country or asset class.

Market Trading Risk. Although fund shares are listed on national securities exchanges, there can be no assurance that an active trading market for fund shares will develop or be maintained. If an active market is not maintained, investors may find it difficult to buy or sell fund shares.

Shares of the Fund May Trade at Prices Other Than NAV. Fund shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of the shares of the fund will approximate the fund’s net asset value (NAV), there may be times when the market price and the NAV vary significantly. An investor may pay more than NAV when buying shares of the fund in the secondary market, and an investor may receive less than NAV when selling those shares in the secondary market. The market price of fund shares may deviate, sometimes significantly, from NAV during periods of market volatility or market disruption, or as a result of other factors impacting foreign securities, including liquidity, irregular trading activity and timing differences between foreign markets where securities trade and the secondary market where fund shares are sold.

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 an index. This information provides some indication of the risks of investing in the fund. All figures assume distributions were reinvested. Keep in mind that future performance (both before and after taxes) may differ from past performance. For current performance information, please see www.schwabfunds.com/schwabetfs_prospectus.

1	The net version of the index reflects reinvested dividends net of withholding taxes, but reflects no deductions for expenses or other taxes.

The after-tax figures reflect the highest individual federal income tax rates in effect during the period and do not reflect the impact of state and local taxes. Your actual after-tax returns depend on your individual tax situation. In addition, after-tax returns are not relevant if you hold your fund shares through a tax-deferred arrangement, such as a 401(k) plan, an individual retirement account (IRA) or other tax-advantaged account. In some cases, the return after taxes on distributions and sale of shares may exceed the fund’s other returns due to an assumed benefit from any losses on a sale of shares at the end of the measurement period.

Purchase and Sale of Fund Shares

The fund issues and redeems shares at its NAV only in large blocks of shares, typically 100,000 shares or more (Creation Units). These transactions are usually in exchange for a basket of securities included in the index and/or an amount of cash. As a practical matter, only Authorized Participants purchase or redeem Creation Units. Except when aggregated in Creation Units, shares of the fund are not redeemable securities.

Individual shares of the fund trade on national securities exchanges and elsewhere during the trading day and can only be bought and sold at market prices throughout the trading day through a broker-dealer. Because fund shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (premium) or less than NAV (discount).

Tax Information

Dividends and capital gains distributions received from the fund will generally be taxable as ordinary income or capital gains, unless you are investing through an IRA, 401(k) or other tax-advantaged account.

Payments to Financial Intermediaries

If you purchase shares of the fund through a broker-dealer or other financial intermediary (such as a bank), the adviser and its related companies may pay the intermediary for the sale of fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other financial intermediary and your salesperson to recommend the fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.
