Investment objective

The fund seeks high current income consistent with preservation of capital.

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)
	None
Annual fund operating expenses (expenses that you pay each year as a % of the value of your investment)
Management fees	0.29
Distribution (12b-1) fees	None
Other expenses	0.31
Total annual fund operating expenses	0.60
Less expense reduction	(0.05	)
Total annual fund operating expenses after expense reduction1	0.55

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 0.55% 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 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.

Expenses on a $10,000 investment

1 year	3 years	5 years	10 years
$56	$176	$307	$689

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 567% of the average value of its portfolio.

Principal investment strategies

To pursue its goal, the fund normally invests at least 80% of its net assets in Government National Mortgage Association (GNMA) securities. The fund will notify its shareholders at least 60 days before changing this policy. In addition to GNMA securities, the fund may invest in securities issued by the U.S. government or its other agencies and instrumentalities, such as the Federal National Mortgage Association (Fannie Mae), Federal Home Loan Mortgage Corporation (Freddie Mac) and Federal Home Loan Banks (FHLBs).

The fund may also invest in mortgage-backed and asset-backed securities, collateralized mortgage obligations, repurchase agreements, and commercial paper. The fund also may invest in derivative instruments, principally futures contracts. The fund typically uses futures as a substitute for taking a position in the underlying asset or as part of a strategy designed to reduce exposure to other risks. The fund is not subject to any maturity or duration restrictions. The fund also may seek to obtain market exposure to the instruments in which it invests by entering into a series of purchase and sale contracts or by using other investment techniques, such as mortgage dollar rolls.

For temporary defensive purposes during unusual market conditions, the fund may invest up to 100% of its assets in cash, cash equivalents or other high quality short-term investments. When the fund engages in such activities, the fund would not be pursuing its investment strategy and, as a result, it may not achieve its investment goal.

The fund may buy and sell portfolio securities actively. If it does, its portfolio turnover rate and transaction costs will rise, which may lower fund performance and increase the likelihood of capital gain distributions.

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. Bond 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.

Management Risk. As an actively managed mutual fund, the fund is subject to the risk that its investment adviser will make poor security selections. The fund’s investment adviser applies its 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.

Interest Rate Risk. Interest rates will rise and fall over time. During periods when interest rates are low, the fund’s yield and total return also may be low. Changes in interest rates also may affect the fund’s share price: a sharp rise in interest rates could cause the fund’s share price to fall. The longer the fund’s duration, the more sensitive to interest rate movements its share price is likely to be.

Credit Risk. The fund is subject to the risk that a decline in the credit quality of a portfolio investment could cause the fund to lose money or underperform. The fund could lose money if the issuer or guarantor of a portfolio investment fails to make timely principal or interest payments or otherwise honor its obligations.

Liquidity Risk. A particular investment may be difficult to purchase or sell. The fund may be unable to sell a security at an advantageous time or price.

Prepayment and Extension Risk. The fund’s investments are subject to the risk that the securities may be paid off earlier or later than expected. Either situation could cause the fund to hold securities paying lower-than-market rates of interest, which could hurt the fund’s yield or share price.

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 and could cause the fund to lose more than the principal 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. However, these risks are less severe when the fund uses derivatives for hedging rather than to enhance the fund’s returns or as a substitute for a position or security.

Mortgage Dollar Rolls Risk. Mortgage dollar rolls are transactions in which the fund sells mortgage-backed securities to a dealer and simultaneously agrees to repurchase similar securities in the future at a predetermined price. The fund’s mortgage dollar rolls could lose money if the price of the mortgage-backed securities sold falls below the agreed upon repurchase price, or if the counterparty is unable to honor the agreement.

Leverage Risk. Certain fund transactions, such as derivatives and mortgage dollar rolls, 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. The use of leverage may cause the fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations.

Lack of Governmental Insurance or Guarantee. An investment in the fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

For more information on the risks of investing in the fund please see the “Fund details” section in the prospectus.

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/prospectus. On August 10, 2009, the Investor Share class and Select Share class were combined into a single class of shares of the fund, and the fund no longer offers multiple classes of shares. The performance history of the fund is that of the fund’s former Select Shares. Accordingly, the past performance information of the fund’s former Select Shares is shown below prior to August 10, 2009.

Annual total returns (%) as of 12/31

Best quarter: 3.54% Q4 2007

Worst quarter: (1.14%) Q2 2004

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, IRA or other tax-advantaged account.
