Summary Prospectus by Investment Company (Form 497K)

Investment Objective

​

The fund's goal is to track as closely as possible, before fees and expenses, the total return of the FTSE Emerging Index.

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.

The information in the table has been restated to reflect current fees and expenses.​

​

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 sell 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.

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 8% of the average value of its portfolio.

Principal Investment Strategies

​

To pursue its goal, the fund generally invests in stocks that are included in the FTSE Emerging Index†. The index is comprised of large and mid capitalization companies in emerging market countries, 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, 2024, the index was composed of 2,212 stocks in 22 emerging 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 purpose, 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 more than 25% of its total assets) in a particular industry, group of industries or sector to approximately the same extent that the index is so concentrated.

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.

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. Errors relating to the index may occur from time to time and may not be identified by the index provider for a period of time. In addition, market disruptions could cause delays in the index's rebalancing schedule. Such errors and/or market disruptions may result in losses for the fund.

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, in particular, many of which are issued by companies in emerging markets, may be more volatile. Foreign securities may also include investments in variable interest entities (VIEs) structures, which are created by China-based operating companies in jurisdictions outside of China to obtain indirect financing due to Chinese regulations that prohibit non-Chinese ownership of those companies. 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.

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 and Correlation Risk. As an index fund, the fund seeks to track the performance of the index, although it may not be successful in doing so. Further, there can be no guarantee that the fund will achieve a high degree of correlation between the fund's performance and that of its index. The correlation between the performance of the fund and that of its 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 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.

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 one or more indices. The MSCI Emerging Markets Index (Net) serves as the fund's regulatory index and provides a broad measure of market performance. The fund generally invests in securities that are included in the FTSE Emerging Index (Net). The fund does not seek to track the regulatory 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

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.

Purchase and Sale of Fund Shares

​

The fund issues and redeems shares at its NAV only in large blocks of shares (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.

Individual shares may only be purchased and sold in the secondary market (i.e., on a national securities exchange) through a broker or dealer at market prices. Because fund shares trade at market prices rather than at NAV, fund shares may trade at a price greater than NAV (premium) or less than NAV (discount). When buying or selling shares in the secondary market, you may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the fund (bid) and the lowest price a seller is willing to accept for shares of the fund (ask) (the "bid-ask spread"). Recent information regarding the fund's NAV, market price, premiums and discounts, and bid-ask spreads is available at www.schwabassetmanagement.com.

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 (in which case you may be taxed later, upon withdrawal of your investment from such 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.
