Schwab Fundamental US Large Company Index Fund

Investment objective

The fund seeks investment results that correspond generally (before fees and expenses) to the total return of the Russell Fundamental U.S. Large Company Index.

Fund fees and expenses

This table describes the fees and expenses you may pay if you buy and hold shares of the fund.

Shareholder fees (fees paid directly from your investment)

Shareholder Fees	Schwab Fundamental US Large Company Index Fund Institutional Shares
Redemption fee (as a % of the amount sold or exchanged within 30 days of purchase)	2.00%

Annual fund operating expenses (expenses that you pay each year as a % of the value of your investment)

Annual Fund Operating Expenses	Schwab Fundamental US Large Company Index Fund Institutional Shares
Management fees	0.23%
Distribution (12b-1) fees	none
Other expenses	0.16%
Total annual fund operating expenses	0.39%
Less expense reduction	(0.04%)
Total annual fund operating expenses after expense reduction	0.35%	[1]

Example

This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual 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 expense reduction. The expenses would be the same whether you stayed in the fund or sold your shares at the end of each period. 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 12% of the average value of its portfolio.

Principal investment strategies

To pursue its goal, the fund primarily invests in stocks that are included in the Russell Fundamental U.S. Large Company Index¹(the index). The index measures the performance of the large company size segment by fundamental overall company scores (scores), which are created using as the universe the companies in the Russell 3000^® Index (the Russell Index). Securities are grouped in order of decreasing score and each company receives a weight based on the total weights of the companies within the Russell Index. Companies are split at the 87.5% point based on fundamental weights. Companies above this breakpoint make up the index. The index uses a partial quarterly reconstitution methodology in which the index is split into four equal segments at the annual reconstitution and each segment is then rebalanced on a rolling quarterly basis. The index is compiled and calculated by Frank Russell Company in conjunction with Research Affiliates LLC, and the method of calculating the components of the index is subject to change.

It is the fund’s policy that, under normal circumstances, it will invest at least 90% of its net assets in stocks included in the index. The fund will notify its shareholders at least 60 days before changing this policy. The fund will generally give the same weight to a given stock as the index does. However, when the investment adviser believes it is in the best interest of the fund, such as to avoid purchasing odd-lots (i.e., purchasing less than the usual number of shares traded for a security), for tax considerations, or to address liquidity considerations with respect to a stock, the investment adviser may cause the fund’s weighting of a stock to be more or less than the index’s weighting of the stock. 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.

The fund uses an “indexing” investment approach, which attempts to replicate, before expenses, the performance of the index by purchasing a basket of securities that compose the index. Using this approach, the investment adviser seeks a correlation, over time, of 0.95 or better between the fund’s performance and the performance of the index; a figure of 1.00 would represent perfect correlation. However, it is possible that the investment adviser may determine to utilize instead a “sampling” methodology in seeking to achieve the fund’s objective. Sampling means that the investment adviser uses quantitative analysis to select stocks from the index universe to obtain a representative sample of stocks that resembles the index in terms of key risk factors, performance attributes and other characteristics. In certain circumstances it may not be possible or practicable for the fund to invest in all of the stocks comprising the index or in proportion to their weightings in the index.

There can be no guarantee that the performance of the fund will achieve a high degree of correlation with that of 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. 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.

Like many index funds, the fund also may invest in derivatives, principally futures contracts, and lend its securities to minimize the gap in performance that exists between any index fund and its corresponding index. This gap occurs mainly because, unlike the index, the fund incurs expenses and must keep a small portion of its assets in cash for business operations. By using futures, the fund can gain market exposure and potentially offset a portion of the gap attributable to its cash holdings. Any income realized through securities lending may help reduce the portion of the gap attributable to expenses.

The fund may concentrate its investments in an industry or group of industries to the extent that the index the fund is designed to track is also 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. Equity markets rise and fall daily. As with any investment whose performance is tied to these markets, the value of your investment in the fund will fluctuate, which means that you could lose money.

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.

Investment Style Risk. The fund invests in companies within the U.S. stock market, as measured by the index. It follows these stocks 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.

A significant percentage of the index may be composed of securities in a single industry or sector of the economy. If the fund is focused in an industry or sector, it may present more risks than if it were broadly diversified over numerous industries and sectors of the economy.

Large-Cap Risk. Although the index encompasses stocks from many different sectors of the economy, its performance primarily reflects that of large company stocks, which tend to go in and out of favor based on market and economic conditions. During a period when large-cap stocks fall behind other types of investments—bonds or small company stocks, for instance — the fund's large-cap holdings could reduce performance.

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. For example, the fund may not invest in certain securities in the index, or match the securities’ weightings to the index, due to regulatory, operational, custodial or liquidity constraints; corporate transactions; asset valuations; transaction costs and timing; tax considerations; and index rebalancing, which may result in tracking error.

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 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 susceptible to adverse economic, market, political or regulatory occurrences affecting that market, industry, group of industries, sector or asset class.

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 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.

Sampling Index Tracking Risk. To the extent the fund uses a sampling method, the fund will 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. When 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.

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

Your investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

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 return before taxes due to an assumed benefit from any losses on a sale of shares at the end of the measurement period.

[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 0.35% 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.
