Investment Objective

The fund seeks long-term total return consistent with its value-oriented investment approach.

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	0.60
Distribution (12b-1) fees	None
Other expenses	0.19
Total annual fund operating expenses	0.79
Less expense reduction	(0.04)
Total annual fund operating expenses after expense reduction1	0.75

¹ The investment adviser has contractually agreed to limit the total annual fund operating expenses (excluding interest, taxes, and certain non-routine expenses) of the fund to 0.75% until at least July 30, 2019. During this term, the agreement may only be amended or terminated with the approval of the fund’s Board of Trustees. Any amounts waived or reimbursed in a particular fiscal year will be subject to reimbursement by the fund to the investment adviser during the next two fiscal years to the extent that the repayment will not cause the fund’s total annual fund operating expenses to exceed the limit (as stated in the agreement) during the respective year or the current year. The investment adviser may, but is not required to, extend the agreement for additional years.

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 one-year figure is 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
$77	$244	$431	$970

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 98% of the average value of its portfolio.

Principal Investment Strategies

The fund invests primarily in fixed income securities that may also provide the potential for capital appreciation. The fund is an international fund that invests primarily in issuers that are organized, have a majority of their assets or derive most of their operating income outside of the United States. As such, it may invest primarily in securities issued in any currency and may hold foreign currency. Under normal circumstances, the fund intends to invest in securities which are denominated in foreign currencies. Securities of issuers within a given country may be denominated in the currency of such country, in the currency of another country or in multinational currency units, such as the euro. The fund will attempt to achieve its objective by investing in a broad range of fixed income securities, including debt obligations of governments, their agencies, instrumentalities or political subdivisions and companies. They will generally be rated, at the time of investment, BBB or better by S&P or Moody’s or, if unrated, are deemed to be of comparable quality by the subadviser. The fund may invest up to 5% of its assets (determined at time of purchase) in fixed-income securities rated below investment grade (sometimes called junk bonds), including government securities as discussed below. The fund may invest up to 20% of its net assets (determined at time of purchase) in corporate debt securities.

The fund may invest up to 5% of its assets (determined at time of purchase) in emerging markets. The fund is considered “non-diversified”, which means that it may invest in the securities of relatively few issuers.

Under normal circumstances, the fund will invest at least 80% of its net assets (including, for this purpose, any borrowings for investment purposes) in fixed income securities issued by governments, government agencies or instrumentalities including government-sponsored entities and supra-national entities. The fund will notify its shareholders at least 60 days before changing this policy.

The subadviser’s approach in selecting investments for the fund is oriented to country selection and is value driven. In selecting fixed income instruments for the fund, the subadviser identifies those countries’ fixed income markets that it believes will provide the United States domiciled investor the highest yield over a market cycle while also offering the opportunity for capital gain and currency appreciation. The subadviser conducts extensive fundamental research on a global basis, and it is through this effort that attractive fixed income markets are selected for investment. The core of the fundamental research effort is a value-oriented prospective real yield approach which looks at today’s yield in each market and subtracts from it forecasted inflation for the next two years to identify value as a forward looking potential real yield. Comparisons of the values of different possible investments are then made. The higher the prospective real yield the higher the relative allocation and conversely the lower the prospective real yield the lower the allocation or even a zero allocation.

The fund may also invest in zero coupon bonds, and in the debt securities of supranational entities denominated in any currency. The fund also may invest in securities issued by the U.S. Government or its agencies and instrumentalities such as Government National Mortgage Association (Ginnie Mae), Federal National Mortgage Association (Fannie Mae) and Federal Home Loan Mortgage Corporation (Freddie Mac).

The fund may actively carry on hedging activities, and may utilize a wide range of derivative instruments, including options, futures contracts and related options, and forward foreign currency exchange contracts to hedge currency risks associated with its portfolio securities. This hedging may be in the form of cross hedging. Hedging and cross hedging may be used to identify value opportunities in the currency markets. The fund may also use derivatives as a substitute for taking a position in the underlying asset. The fund may lend its securities to certain financial institutions to earn additional income.

The fund may buy and sell portfolio securities actively. As a result, the fund’s portfolio turnover rate and transaction costs will rise, which may lower fund performance and may increase the likelihood of capital gain distributions.

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. 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. 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. As with all actively managed funds, the fund is subject to the risk that its subadviser will select investments or allocate assets in a manner that could cause the fund to underperform or otherwise not meet its objective. Poor bond selection or a focus on securities in a particular region may cause the fund to underperform its benchmark or other funds with a similar investment objective.

Non-Diversification Risk. The fund is non-diversified and, as such, may invest a greater percentage of its assets in the securities of a single issuer than a fund that is diversified. A non-diversified fund is more susceptible to risks associated with a single economic, political or regulatory occurrence than a diversified fund.

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. The longer the fund’s duration, the more sensitive to interest rate movements its share price is likely to be. Because interest rates in the United States are at, or near, historically low levels, a change in a central bank’s monetary policy or improving economic conditions may result in an increase in interest rates.

Credit Risk. The fund is subject to the risk that a decline in the credit quality of a portfolio investment could cause the fund’s share price to fall. The fund could lose money if the issuer of a portfolio investment fails to make timely principal or interest payments or if a guarantor or counterparty of a portfolio investment fails to honor its obligations. Securities rated below investment grade (junk bonds) involve greater risk of price declines than investment grade securities due to actual or perceived changes in the issuer’s creditworthiness.

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.

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 or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency hedged, resulting in the dollar value of the fund’s investment being adversely affected. 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.

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 and reporting 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 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.

Leverage Risk. Certain fund transactions, such as derivatives, may give rise to a form of leverage and may expose the fund to greater risk. Leverage tends to magnify the effect of any increase or decrease in the value of the fund’s portfolio securities, which means even a small amount of leverage 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.

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/laudusfunds_prospectus.

On July 27, 2009, the Investor Share class, Select Share class and Institutional 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 Institutional Shares. Accordingly, the past performance information of the fund’s former Institutional Shares is shown below.

Annual Total Returns (%) as of 12/31

Best Quarter: 11.42% Q1 2008
Worst Quarter: (11.17%) Q4 2016
Year-to-date performance (non-annualized and before taxes) as of 6/30/2017: 7.29%

Average Annual Total Returns as of 12/31/16
	1 Year	5 Years	Since Inception (11/2/07)
Before Taxes	0.05%	(2.97%)	1.52%
After Taxes on Distributions	(0.12%)	(3.43%)	0.72%
After Taxes on Distributions and Sale of Shares	0.16%	(2.23%)	1.02%
Comparative Index (reflects no deduction for expenses or taxes)
Citigroup Non-U.S. Dollar World Government Bond Index	1.81%	(1.94%)	1.73%

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. In some cases, the return after taxes 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.
