Investment objectives, strategies and risks

The following is a description of the investment objectives, investment strategies and principal risks of the Laudus Mondrian International Equity Fund, Laudus Mondrian Global Equity Fund, Laudus Mondrian Emerging Markets Fund and Laudus Mondrian International Fixed Income Fund. Except as explicitly described otherwise, the investment objective and policies of each of the funds may be changed without shareholder approval.

Laudus Mondrian International Equity Fund

Investment objective

The fund seeks long-term capital appreciation.

The fund’s investment objective is not fundamental, and therefore, may be changed by the fund’s Board of Trustees without shareholder approval.

Investment strategies

The fund pursues its investment objective primarily by investing in equity securities of non-U.S. large capitalization issuers, including the securities of emerging market companies, that, in the subadviser’s opinion, are undervalued at the time of purchase based on fundamental value analysis employed by the subadviser. Normally, the fund will invest primarily in common stocks. The fund may purchase securities of non-U.S. issuers directly or indirectly in the form of American, European or Global depositary receipts or other securities representing underlying shares of non-U.S. issuers. The fund may also purchase other investment funds, including, but not limited to, registered funds, including exchange-traded funds (ETFs), unregistered funds and real estate investment trusts (REITs).

For purposes of investments to be made by the fund, large capitalization companies are currently defined by the subadviser to mean issuers that have a market capitalization of more than $6.5 billion at the time of purchase. This level is subject to market movements and is regularly reviewed by the subadviser. Typically, the fund invests in securities of approximately 30-40 companies.

Under normal circumstances, the fund will invest at least 80% of its net assets (including, for this purpose, any borrowings for investment purposes) in equity securities. 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 primarily oriented to individual stock selection and is value driven. In selecting stocks for the fund, the subadviser identifies those stocks that it believes will provide capital appreciation over a market cycle, taking into consideration movements in the price of the individual security and the impact of currency fluctuation on a United States domiciled, dollar-based investor. The subadviser conducts fundamental research on a global basis in order to identify securities that, in the subadviser’s opinion, have the potential for long-term capital appreciation. This research effort generally centers on a value-oriented dividend discount methodology with respect to individual securities and market analysis that isolates value across country boundaries. The approach focuses on future anticipated dividends and discounts the value of those dividends back to what they would be worth if they were being received today. In addition, the analysis typically includes a comparison of the values and current market prices of different possible investments. The subadviser’s general management strategy emphasizes long-term holding of securities, although securities may be sold in the subadviser’s discretion without regard to the length of time they have been held.

Investments will be made mainly in marketable securities of companies located in developed countries including but not limited to Australia, Belgium, Canada, Denmark, Finland, France, Germany, Hong Kong, Ireland, Italy, Japan, the Netherlands, New Zealand, Norway, Singapore, Spain, Sweden, Switzerland and the United Kingdom. The fund may also invest in securities of companies located in emerging countries.

The fund considers an “emerging country” to be any country except the United States, Canada, and those in the MSCI EAFE Index. In considering possible emerging countries in which the fund may invest, the subadviser places particular emphasis on certain factors, such as economic conditions (including growth trends, inflation rates and trade balances), regulatory and currency controls, accounting standards and political and social conditions.

Currency considerations carry a special risk for a portfolio of international securities. The fund may invest in securities issued in any currency and may hold foreign currency. Securities of issuers within a given country may be denominated in the currency of another country or in multinational currency units, including the euro. The subadviser primarily uses a purchasing power parity approach to evaluate currency risk. In this regard, the fund may carry out hedging activities and may invest in forward foreign currency exchange contracts to hedge currency risks associated with the purchase of individual securities denominated in a particular currency. Under normal circumstances, hedging is undertaken defensively back into the base currency of the fund.

The fund may also invest in debt securities issued by governments or by their agencies, instrumentalities or political subdivisions, or by corporate entities, all of which may be high-yield, high-risk fixed income securities rated below investment-grade (sometimes called junk bonds) or, if unrated, considered to be of equivalent quality by the subadviser. In addition, for temporary defensive purposes, the fund may invest in high-quality debt instruments.

The fund may invest in derivative instruments, such as futures contracts. The fund typically uses derivatives 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 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 increase the likelihood of capital gain distributions. The turnover rate may also be affected by cash requirements from redemptions of the fund’s shares.

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.

Market risk. Stock and bond markets and the values of the securities owned by the fund 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 with all actively managed funds, the strategies of the fund’s subadviser may not achieve their desired results. The subadviser 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. These risks may cause the fund to underperform its benchmark or other funds with a similar investment objective.

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. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. In addition, the equity market tends to move in cycles which may cause stock prices to fall over short or extended periods of time.

Large-cap risk. Many of the risks of this fund are associated with its investments in the large-cap segments of the stock market. Large-cap stocks 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-cap stocks, for instance — the fund’s performance also will lag those investments.

Foreign investment risk. Investments in securities of foreign issuers involve certain risks that are more significant 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, or changes in currency exchange rates or exchange control regulations (including limitations on currency movements and exchanges). In certain countries, legal remedies available to investors may be more limited than those available with respect to investments in the United States. The securities of some foreign companies may be less liquid and at times more volatile than securities of comparable U.S. companies. A fund with foreign investments may also experience more rapid or extreme changes in value than a fund that invests solely in securities of U.S. companies because the securities markets of many foreign countries are relatively small, with a limited number of companies representing a small number of industries. There also is the risk that the cost of buying, selling, and holding foreign securities, including brokerage, tax, and custody costs, may be higher than those involved in domestic transactions.

Foreign government securities can involve a high degree of risk. The governmental entity that controls the repayment of sovereign debt may not be able or willing to repay the principal and/or interest when due in accordance with the terms of the debt. A governmental entity’s willingness or ability to repay principal and interest due in a timely manner may be affected by, among other factors, its cash flow situation, the extent of its foreign reserves, the availability of sufficient foreign exchange on the date a payment is due, the relative size of the debt service burden to the economy as a whole, the governmental entity’s policy toward the International Monetary Fund, and the political constraints to which a governmental entity may be subject. Governmental entities also may depend on expected disbursements from foreign governments, multilateral agencies and others to reduce principal and interest arrearages on their debt.

Emerging markets risk. Emerging markets 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, unreliable securities valuation and greater risk associated with the custody of securities. It is sometimes difficult to obtain and enforce court judgments in such countries and there is often a greater potential for nationalization and/or expropriation of assets by the government of an emerging market country. In addition, the financial stability of issuers (including governments) in emerging market

Table of Contents

countries may be more precarious than in other countries. As a result, there will tend to be an increased risk of 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.

Currency risk. As a result of its investments in securities denominated in, and/or receiving revenues in, foreign currencies, the fund will be subject to currency risk. This is the risk that those 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. In either event, the dollar value of an investment in the fund would be adversely affected. Currency exchange rates may fluctuate in response to factors extrinsic to that country’s economy, which makes the forecasting of currency market movements extremely difficult. Currency rates in foreign countries may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates, intervention (or failure to intervene) by U.S. or foreign governments, central banks or supranational entities such as the International Monetary Fund, or by the imposition of currency controls or other political developments in the United States or abroad. These can result in losses to the fund if it is unable to deliver or receive currency or funds in settlement of obligations and could also cause hedges it has entered into to be rendered useless, resulting in full currency exposure as well as incurring transaction costs. Forward contracts on foreign currencies are not traded on exchanges; rather, a bank or dealer will act as agent or as principal in order to make or take future delivery of a specified lot of a particular currency for the fund’s account. The fund is subject to the risk of a principal’s failure, inability or refusal to perform with respect to such contracts.

Derivatives risk. Examples of derivatives are options, futures, options on futures, swaps and warrants. An option is the right to buy or sell an instrument at a specific price before a specific date. A future is an agreement to buy or sell a financial instrument at a specific price on a specific day. A swap is an agreement whereby two parties agree to exchange payment streams calculated in relation to a rate, index, instrument or certain securities and a predetermined amount. A credit default swap is an agreement in which the seller agrees to make a payment to the buyer in the event of a specified credit event in exchange for a fixed payment or series of fixed payments. A warrant is a security that gives the holder the right, but not the obligation, to subscribe for newly created equity issues of the issuing company or a related company at a fixed price either on a certain date or during a set period. Changes in the value of a warrant do not necessarily correspond to changes in the value of its underlying security. The price of a warrant may be more volatile than the price of its underlying security, and a warrant may offer greater potential for capital appreciation as well as capital loss. Warrants do not entitle a holder to dividends or voting rights with respect to the underlying security and do not represent any rights in the assets of the issuing company.

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. Certain of these risks, such as liquidity risk, credit risk, leverage risk, market risk and management risk, are discussed elsewhere in this section. The fund’s use of derivatives is also subject to lack of availability risk, valuation risk, correlation risk and tax risk. Lack of availability risk is the risk that suitable derivative transactions may not be available in all circumstances for risk management or other purposes. Valuation risk is the risk that a particular derivative may be valued incorrectly. Correlation risk is the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Tax risk is the risk that the use of derivatives may cause the fund to realize higher amounts of short-term capital gain. These risks could cause the fund to lose more than the principal amount invested.

Interest rate risk. The fund’s investments in fixed income securities are subject to the risk that interest rates rise and fall over time. As with any investment whose yield reflects current interest rates, the fund’s yield will change over time. During periods when interest rates are low, the fund’s yield (and total return) also may be low. When interest rates rise, bond prices usually fall which 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’s investments in fixed income securities are 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 or guarantor of a portfolio investment or the counterparty to a derivatives contract fails to make timely principal or interest payments or otherwise honor its obligations. Securities rated below investment-grade (junk bonds) involve greater risks of default or downgrade and are more volatile than investment-grade securities. Below investment-grade securities involve greater risk of price declines than investment-grade securities due to actual or perceived changes in an issuer’s creditworthiness. In addition, issuers of below investment-grade securities may be more susceptible than other issuers to economic downturns. Such securities are subject to the risk that the issuer may not be able to pay interest or dividends and ultimately to repay principal upon maturity. Discontinuation of these payments could substantially adversely affect the market value of the securities.

Prepayment and extension risk. The fund’s investments in fixed income securities 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. In addition, rising interest rates tend to extend the duration of certain fixed income securities, making them more sensitive to changes in interest rates. As a result, in a period of rising interest rates, the fund may exhibit additional volatility. This is known as extension risk. When interest rates decline, borrowers may pay off their fixed income securities sooner than expected. This can reduce the returns of the fund because the fund will have to reinvest that money at the lower prevailing interest rates. This is known as prepayment risk.

Convertible securities risk. A convertible security is a bond, debenture, note, preferred stock or other security that may be converted into or exercised for a prescribed amount of common stock at a specified time and price. Convertible securities provide an opportunity for equity participation, with the potential for a higher dividend or interest yield and lower price volatility compared to common stock. The value of a convertible security is influenced by changes in interest rates, with investment value declining as interest rates increase and increasing as interest rates decline, and the credit standing of the issuer. The price of a convertible security will also normally vary in some proportion to changes in the price of the underlying common stock because of the conversion or exercise feature.

Securities lending risk. The fund may lend its portfolio securities to brokers, dealers and other financial institutions provided a number of conditions are satisfied, including that the loan is fully collateralized. When the fund lends portfolio securities, its investment performance will continue to reflect changes in the value of the securities loaned, and the fund also will receive a fee or interest on the collateral. 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. The fund will also bear the risk of any decline in value of securities acquired with cash collateral. The fund may pay lending fees to a party arranging the loan.

Exchange traded fund (ETF) risk. The fund may purchase shares of ETFs to gain exposure to a particular portion of the market while awaiting an opportunity to purchase securities directly. When the fund invests in an ETF, in addition to directly bearing the expenses associated with its own operations, it will bear a pro rata portion of the ETF’s expenses. Therefore, it may be more costly to own an ETF than to own the underlying securities directly. In addition, while the risks of owning shares of an ETF generally reflect the risks of owning the underlying securities the ETF is designed to track, lack of liquidity in an ETF can result in its value being more volatile than the underlying portfolio securities.

REITs risk. The fund’s investments in REITs will be subject to the risks associated with the direct ownership of real estate. Risks commonly associated with the direct ownership of real estate include fluctuations in the value of underlying properties, defaults by borrowers or tenants, possible lack of availability of mortgage funds or other limits to accessing the credit or capital markets, increases in property taxes and operating expenses, changes in zoning laws, overbuilding, extended vacancies of properties, changes in interest rates and risks related to general or local economic conditions. In addition to the risks associated with investing in securities of real estate companies and real estate related companies, REITs are subject to certain additional risks. Equity REITs may be affected by changes in the value of the underlying properties owned by the trusts, and mortgage REITs may be affected by the quality of any credit extended. Further, REITs are dependent upon specialized management skills and may have their investments in relatively few properties, or in a small geographic area or a single property type. REITs are also subject to heavy cash flow dependency, defaults by borrowers and self-liquidation. In addition, REITs could possibly fail to qualify for tax free pass-through of income under the Internal Revenue Code. The failure of a company to qualify as a REIT under federal tax law may have adverse consequences to the fund. In addition, REITs have their own expenses and the fund will bear a proportionate share of those expenses.

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 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.

Liquidity risk. Liquidity risk exists when particular investments are difficult to purchase or sell. The market for certain investments may become illiquid due to specific adverse changes in the conditions of a particular issuer or under adverse market or economic conditions independent of the issuer. The fund’s investments in illiquid securities may reduce the returns of the fund because it may be unable to sell the illiquid securities at an advantageous time or price. Further, transactions in illiquid securities may entail transaction costs that are higher than those for transactions in liquid securities.

The prices of securities issued by such companies may suffer a decline in response. In addition, the equity market tends to move in cycles which may cause stock prices to fall over short or extended periods of time.

Table of Contents

Large- and mid-cap risk. Both large- and mid-cap stocks tend to go in and out of favor based on market and economic conditions. However, stocks of mid-cap companies tend to be more volatile than those of large-cap companies because mid-cap companies tend to be more susceptible to adverse business or economic events than larger more established companies. During a period when large- and mid-cap stocks fall behind other types of investments — small-cap stocks, for instance — the fund’s performance could be reduced to the extent its portfolio is holding large-or mid-cap stocks.

Small-cap risk. Historically, small-cap stocks have been riskier than large-and mid-cap stocks. Stock prices of smaller companies may be based in substantial part on future expectations rather than current achievements and may move sharply, especially during market upturns and downturns. Small-cap companies themselves may be more vulnerable to adverse business or economic events than larger, more established companies. In addition, smaller companies may have limited financial resources, product lines and markets, and their securities may trade less frequently and in more limited volumes than the securities of larger companies. Further, smaller companies may have less publicly available information and, when available, it may be inaccurate or incomplete. During a period when small-cap stocks fall behind other types of investments — large-cap stocks, for instance — the fund’s performance could be reduced to the extent its portfolio is holding small-cap stocks.

Foreign investment risk. Investments in securities of foreign issuers involve certain risks that are more significant 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, or changes in currency exchange rates or exchange control regulations (including limitations on currency movements and exchanges). In certain countries, legal remedies available to investors may be more limited than those available with respect to investments in the United States. The securities of some foreign companies may be less liquid and at times more volatile than securities of comparable U.S. companies. A fund with foreign investments may also experience more rapid or extreme changes in value than a fund that invests solely in securities of U.S. companies because the securities markets of many foreign countries are relatively small, with a limited number of companies representing a small number of industries. There also is the risk that the cost of buying, selling, and holding foreign securities, including brokerage, tax, and custody costs, may be higher than those involved in domestic transactions.

Foreign government securities can involve a high degree of risk. The governmental entity that controls the repayment of sovereign debt may not be able or willing to repay the principal and/or interest when due in accordance with the terms of the debt. A governmental entity’s willingness or ability to repay principal and interest due in a timely manner may be affected by, among other factors, its cash flow situation, the extent of its foreign reserves, the availability of sufficient foreign exchange on the date a payment is due, the relative size of the debt service burden to the economy as a whole, the governmental entity’s policy toward the International Monetary Fund, and the political constraints to which a governmental entity may be subject. Governmental entities also may depend on expected disbursements from foreign governments, multilateral agencies and others to reduce principal and interest arrearages on their debt.

Emerging markets risk. Emerging markets 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, unreliable securities valuation and greater risk associated with the custody of securities. It is sometimes difficult to obtain and enforce court judgments in such countries and there is often a greater potential for nationalization and/or expropriation of assets by the government of an emerging market country. In addition, the financial stability of issuers (including governments) in emerging market countries may be more precarious than in other countries. As a result, there will tend to be an increased risk of 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.

Currency risk. As a result of its investments in securities denominated in, and/or receiving revenues in, foreign currencies, the fund will be subject to currency risk. This is the risk that those 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. In either event, the dollar value of an investment in the fund would be adversely affected. Currency exchange rates may fluctuate in response to factors extrinsic to that country’s economy, which makes the forecasting of currency market movements extremely difficult. Currency rates in foreign countries may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates, intervention (or failure to intervene) by U.S. or foreign governments, central banks or supranational entities such as the International Monetary Fund, or by the imposition of currency controls or other political developments in the United States or abroad. These can result in losses to the fund if it is unable to deliver or receive currency or funds in settlement of obligations and could also cause hedges it has entered into to be rendered useless, resulting in full currency exposure as well as incurring transaction costs. Forward contracts on foreign currencies are not traded on exchanges; rather, a bank or dealer will act as agent or as principal in order to make or take future delivery of a specified lot of a particular currency for the fund’s account. The fund is subject to the risk of a principal’s failure, inability or refusal to perform with respect to such contracts.

Derivatives risk. The fund may use derivatives to enhance returns or hedge against market declines. Examples of derivatives are options, futures, options on futures, swaps and warrants. An option is the right to buy or sell an instrument at a specific price before a specific date. A future is an agreement to buy or sell a financial instrument at a specific price on a specific day. A swap is an agreement whereby two parties agree to exchange payment streams calculated in relation to a rate, index, instrument or certain securities and a predetermined amount. A

Table of Contents

credit default swap is an agreement in which the seller agrees to make a payment to the buyer in the event of a specified credit event in exchange for a fixed payment or series of fixed payments. A warrant is a security that gives the holder the right, but not the obligation, to subscribe for newly created equity issues of the issuing company or a related company at a fixed price either on a certain date or during a set period. Changes in the value of a warrant do not necessarily correspond to changes in the value of its underlying security. The price of a warrant may be more volatile than the price of its underlying security, and a warrant may offer greater potential for capital appreciation as well as capital loss. Warrants do not entitle a holder to dividends or voting rights with respect to the underlying security and do not represent any rights in the assets of the issuing company.

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. Certain of these risks, such as liquidity risk, credit risk, leverage risk, market risk and management risk, are discussed elsewhere in this section. The fund’s use of derivatives is also subject to lack of availability risk, valuation risk, correlation risk and tax risk. Lack of availability risk is the risk that suitable derivative transactions may not be available in all circumstances for risk management or other purposes. Valuation risk is the risk that a particular derivative may be valued incorrectly. Correlation risk is the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Tax risk is the risk that the use of derivatives may cause the fund to realize higher amounts of short-term capital gain. These risks could cause the fund to lose more than the principal amount invested.

Interest rate risk. The fund’s investments in fixed income securities are subject to the risk that interest rates rise and fall over time. As with any investment whose yield reflects current interest rates, the fund’s yield will change over time. During periods when interest rates are low, the fund’s yield (and total return) also may be low. When interest rates rise, bond prices usually fall which 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’s investments in fixed income securities are 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 or guarantor of a portfolio investment or the counterparty to a derivatives contract fails to make timely principal or interest payments or otherwise honor its obligations. Securities rated below investment-grade (junk bonds) involve greater risks of default or downgrade and are more volatile than investment-grade securities. Below investment-grade securities involve greater risk of price declines than investment-grade securities due to actual or perceived changes in an issuer’s creditworthiness. In addition, issuers of below investment-grade securities may be more susceptible than other issuers to economic downturns. Such securities are subject to the risk that the issuer may not be able to pay interest or dividends and ultimately to repay principal upon maturity. Discontinuation of these payments could substantially adversely affect the market value of the securities.

Prepayment and extension risk. The fund’s investments in fixed income securities 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. In addition, rising interest rates tend to extend the duration of certain fixed income securities, making them more sensitive to changes in interest rates. As a result, in a period of rising interest rates, the fund may exhibit additional volatility. This is known as extension risk. When interest rates decline, borrowers may pay off their fixed income securities sooner than expected. This can reduce the returns of the fund because the fund will have to reinvest that money at the lower prevailing interest rates. This is known as prepayment risk.

Convertible securities risk. A convertible security is a bond, debenture, note, preferred stock or other security that may be converted into or exercised for a prescribed amount of common stock at a specified time and price. Convertible securities provide an opportunity for equity participation, with the potential for a higher dividend or interest yield and lower price volatility compared to common stock. The value of a convertible security is influenced by changes in interest rates, with investment value declining as interest rates increase and increasing as interest rates decline, and the credit standing of the issuer. The price of a convertible security will also normally vary in some proportion to changes in the price of the underlying common stock because of the conversion or exercise feature.

Securities lending risk. The fund may lend its portfolio securities to brokers, dealers and other financial institutions provided a number of conditions are satisfied, including that the loan is fully collateralized. When the fund lends portfolio securities, its investment performance will continue to reflect changes in the value of the securities loaned, and the fund also will receive a fee or interest on the collateral. 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. The fund will also bear the risk of any decline in value of securities acquired with cash collateral. The fund may pay lending fees to a party arranging the loan.

Exchange traded fund (ETF) risk. The fund may purchase shares of ETFs to gain exposure to a particular portion of the market while awaiting an opportunity to purchase securities directly. When the fund invests in an ETF, in addition to directly bearing the expenses associated with its own operations, it will bear a pro rata portion of the ETF’s expenses. Therefore, it may be more costly to own an ETF than to own the underlying securities directly. In addition, while the risks of owning shares of an ETF generally reflect the risks of owning the underlying securities the ETF is designed to track, lack of liquidity in an ETF can result in its value being more volatile than the underlying portfolio securities.

Table of Contents

REITs risk. The fund’s investments in REITs will be subject to the risks associated with the direct ownership of real estate. Risks commonly associated with the direct ownership of real estate include fluctuations in the value of underlying properties, defaults by borrowers or tenants, possible lack of availability of mortgage funds or other limits to accessing the credit or capital markets, increases in property taxes and operating expenses, changes in zoning laws, overbuilding, extended vacancies of properties, changes in interest rates and risks related to general or local economic conditions. In addition to the risks associated with investing in securities of real estate companies and real estate related companies, REITs are subject to certain additional risks. Equity REITs may be affected by changes in the value of the underlying properties owned by the trusts, and mortgage REITs may be affected by the quality of any credit extended. Further, REITs are dependent upon specialized management skills and may have their investments in relatively few properties, or in a small geographic area or a single property type. REITs are also subject to heavy cash flow dependency, defaults by borrowers and self-liquidation. In addition, REITs could possibly fail to qualify for tax free pass-through of income under the Internal Revenue Code. The failure of a company to qualify as a REIT under federal tax law may have adverse consequences to the fund. In addition, REITs have their own expenses, and the fund will bear a proportionate share of those expenses.

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 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.

Liquidity risk. Liquidity risk exists when particular investments are difficult to purchase or sell. The market for certain investments may become illiquid due to specific adverse changes in the conditions of a particular issuer or under adverse market or economic conditions independent of the issuer. The fund’s investments in illiquid securities may reduce the returns of the fund because it may be unable to sell the illiquid securities at an advantageous time or price. Further, transactions in illiquid securities may entail transaction costs that are higher than those for transactions in liquid securities.

Laudus Mondrian Emerging Markets Fund

Investment objective

The fund seeks long-term capital appreciation.

The fund’s investment objective is not fundamental, and therefore, may be changed by the fund’s Board of Trustees without shareholder approval.

Investment strategies

The fund is an international fund and generally invests in large capitalization equity securities of emerging market companies, as described below, that, in the subadviser’s opinion, are undervalued at the time of purchase based on fundamental value analysis employed by the subadviser. Normally, the fund will invest primarily in common stocks. The fund may also purchase other investment funds, including, but not limited to, registered funds, including exchange-traded funds (ETFs). The fund may purchase securities of non-U.S. issuers directly or indirectly in the form of American, European or Global depositary receipts or other securities representing underlying shares of non-U.S. issuers. The subadviser currently defines companies with large market capitalizations generally, as those with market capitalizations of $3.5 billion or more at the time of purchase. To the extent that the fund invests in convertible debt securities, those securities will be purchased on the basis of their equity characteristics, and ratings of those securities, if any, will not be an important factor in their selection. Typically, the fund invests in securities of approximately 35-45 companies.

Under normal circumstances, the fund will invest at least 80% of its net assets (including, for this purpose, any borrowings for investment purposes) in the securities of emerging markets issuers. 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 primarily oriented to individual stock selection and is value driven. In selecting stocks for the fund, the subadviser identifies those stocks that it believes will provide high total return over a market cycle, taking into consideration movements in the price of the individual security and the impact of currency fluctuation on a United States domiciled, dollar-based investor. The subadviser conducts fundamental research on a global basis in order to identify securities that, in the subadviser’s opinion, have the potential for long-term total return. This research effort generally centers on a value-oriented dividend discount methodology with respect to individual securities and market analysis that isolates value across country boundaries. The approach focuses on future anticipated dividends and discounts the value of those dividends back to what they would be worth if they were being received today. In addition, the analysis typically includes a comparison of the values and current market prices of different possible investments. The subadviser’s general management strategy emphasizes long-term holding of securities, although securities may be sold in the subadviser’s discretion without regard to the length of time they have been held.

The fund considers an “emerging country” to be any country except the United States, Canada, and those in the MSCI EAFE Index.

Table of Contents

In considering possible emerging countries in which the fund may invest, the subadviser will place particular emphasis on factors such as economic conditions (including growth trends, inflation rates, and trade balances), regulatory and currency controls, accounting standards, and political and social conditions.

Although this is not an exclusive list, the subadviser considers an emerging country security to be one that is issued by a company that exhibits one or more of the following characteristics: (1) its principal securities trading market is in an emerging country, as defined above; (2) while traded in any market, alone or on a consolidated basis, the company derives 50% or more of its annual revenues or annual profits from either goods produced, sales made or services performed in emerging countries; (3) the company has 50% of more of its assets located in an emerging country; or (4) it is organized under the laws of, and has a principal office in, an emerging country. The subadviser determines eligibility based on publicly available information and inquiries made of the companies.

Currently, investing in many emerging countries is not feasible, or may, in the subadviser’s opinion, involve unacceptable political or governance risks. The fund focuses its investments in those emerging countries where the subadviser considers the economies to be developing strongly and where the markets are becoming more sophisticated.

The fund may invest in securities issued in any currency and may hold foreign currency. Securities of issuers within a given country may be denominated in the currency of another country or in multinational currency units, including the euro. Currency considerations carry a special risk for a portfolio of international securities. The subadviser primarily uses a purchasing power parity approach to evaluate currency risk. In this regard, the fund may actively carry on hedging activities, and may invest in forward foreign currency exchange contracts to hedge currency risks associated with the purchase of individual securities denominated in a particular currency.

The fund may invest in derivative instruments, such as futures contracts. The fund typically uses derivatives 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 may lend its securities to certain financial institutions to earn additional income.

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.

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 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.

Market risk. Stock markets and the value of the investments owned by the fund 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 with all actively managed funds, the strategies of the fund’s subadviser may not achieve their desired results. The subadviser 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. These risks may cause the fund to underperform its benchmark or other funds with a similar investment objective.

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. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. In addition, the equity market tends to move in cycles which may cause stock prices to fall over short or extended periods of time.

Large-cap risk. Many of the risks of this fund are associated with its investments in the large-cap segments of the stock market. Large-cap stocks 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-cap stocks, for instance — the fund’s performance also will lag those investments.

Foreign investment risk. Investments in securities of foreign issuers involve certain risks that are more significant 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, or changes in currency exchange rates or exchange control regulations (including limitations on currency movements and exchanges). In certain countries, legal remedies available to investors may be more limited than those available with respect to investments in the United States. The securities of some foreign companies may be less liquid and at times more volatile than securities of comparable U.S. companies. A fund with foreign investments may also experience more rapid or extreme changes in value than a fund that invests solely in securities of U.S. companies because the securities markets of many foreign countries are relatively small, with a limited number of companies representing a small number of industries. There also is the risk that the cost of buying, selling, and holding foreign securities, including brokerage, tax, and custody costs, may be higher than those involved in domestic transactions.

Table of Contents

Emerging markets risk. Emerging markets 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, unreliable securities valuation and greater risk associated with the custody of securities. It is sometimes difficult to obtain and enforce court judgments in such countries and there is often a greater potential for nationalization and/or expropriation of assets by the government of an emerging market country. In addition, the financial stability of issuers (including governments) in emerging market countries may be more precarious than in other countries. As a result, there will tend to be an increased risk of 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.

Currency risk. As a result of its investments in securities denominated in, and/or receiving revenues in, foreign currencies, the fund will be subject to currency risk. This is the risk that those 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. In either event, the dollar value of an investment in the fund would be adversely affected. Currency exchange rates may fluctuate in response to factors extrinsic to that country’s economy, which makes the forecasting of currency market movements extremely difficult. Currency rates in foreign countries may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates, intervention (or failure to intervene) by U.S. or foreign governments, central banks or supranational entities such as the International Monetary Fund, or by the imposition of currency controls or other political developments in the United States or abroad. These can result in losses to the fund if it is unable to deliver or receive currency or funds in settlement of obligations and could also cause hedges it has entered into to be rendered useless, resulting in full currency exposure as well as incurring transaction costs. Forward contracts on foreign currencies are not traded on exchanges; rather, a bank or dealer will act as agent or as principal in order to make or take future delivery of a specified lot of a particular currency for the fund’s account. The fund is subject to the risk of a principal’s failure, inability or refusal to perform with respect to such contracts.

Derivatives risk. Examples of derivatives are options, futures, options on futures, swaps and warrants. An option is the right to buy or sell an instrument at a specific price before a specific date. A future is an agreement to buy or sell a financial instrument at a specific price on a specific day. A swap is an agreement whereby two parties agree to exchange payment streams calculated in relation to a rate, index, instrument or certain securities and a predetermined amount. A credit default swap is an agreement in which the seller agrees to make a payment to the buyer in the event of a specified credit event in exchange for a fixed payment or series of fixed payments. A warrant is a security that gives the holder the right, but not the obligation, to subscribe for newly created equity issues of the issuing company or a related company at a fixed price either on a certain date or during a set period. Changes in the value of a warrant do not necessarily correspond to changes in the value of its underlying security. The price of a warrant may be more volatile than the price of its underlying security, and a warrant may offer greater potential for capital appreciation as well as capital loss. Warrants do not entitle a holder to dividends or voting rights with respect to the underlying security and do not represent any rights in the assets of the issuing company.

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. Certain of these risks, such as liquidity risk, leverage risk, market risk and management risk, are discussed elsewhere in this section. The fund’s use of derivatives is also subject to credit risk, lack of availability risk, valuation risk, correlation risk and tax risk. Credit risk is the risk that the fund could lose money if the counterparty to a derivatives contract fails to make timely principal or interest payments or otherwise honor its obligations. Lack of availability risk is the risk that suitable derivative transactions may not be available in all circumstances for risk management or other purposes. Valuation risk is the risk that a particular derivative may be valued incorrectly. Correlation risk is the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Tax risk is the risk that the use of derivatives may cause the fund to realize higher amounts of short-term capital gain. These risks could cause the fund to lose more than the principal amount invested.

Securities lending risk. The fund may lend its portfolio securities to brokers, dealers and other financial institutions provided a number of conditions are satisfied, including that the loan is fully collateralized. When the fund lends portfolio securities, its investment performance will continue to reflect changes in the value of the securities loaned, and the fund also will receive a fee or interest on the collateral. 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. The fund will also bear the risk of any decline in value of securities acquired with cash collateral. The fund may pay lending fees to a party arranging the loan.

Exchange traded fund (ETF) risk. The fund may purchase shares of ETFs to gain exposure to a particular portion of the market while awaiting an opportunity to purchase securities directly. When the fund invests in an ETF, in addition to directly bearing the expenses associated with its own operations, it will bear a pro rata portion of the ETF’s expenses. Therefore, it may be more costly to own an ETF than to own the underlying securities directly. In addition, while the risks of owning shares of an ETF generally reflect the risks of owning the underlying securities the ETF is designed to track, lack of liquidity in an ETF can result in its value being more volatile than the underlying portfolio securities.

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 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.

Convertible securities risk. A convertible security is a bond, debenture, note, preferred stock or other security that may be converted into or exercised for a prescribed amount of common stock at a specified time and price. Convertible securities provide an opportunity for equity participation, with the potential for a higher dividend or interest yield and lower price volatility compared to common stock. The value of a convertible security is influenced by changes in interest rates, with investment value declining as interest rates increase and increasing as interest rates decline, and the credit standing of the issuer. The price of a convertible security will also normally vary in some proportion to changes in the price of the underlying common stock because of the conversion or exercise feature.

Liquidity risk. Liquidity risk exists when particular investments are difficult to purchase or sell. The market for certain investments may become illiquid due to specific adverse changes in the conditions of a particular issuer or under adverse market or economic conditions independent of the issuer. The fund’s investments in illiquid securities may reduce the returns of the fund because it may be unable to sell the illiquid securities at an advantageous time or price. Further, transactions in illiquid securities may entail transaction costs that are higher than those for transactions in liquid securities.

Laudus Mondrian International Fixed Income Fund

Investment objective

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

The fund’s investment objective is not fundamental, and therefore, may be changed by the fund’s Board of Trustees without shareholder approval.

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 in securities issued in any currency and may hold foreign currency. Under normal circumstances, the fund intends to invest primarily 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 5% of its assets (determined at time of purchase) in emerging markets. The fund considers an “emerging country” to be any country except those in either the Citigroup Non-U.S. Dollar World Government Bond Index or the JP Morgan Government Bond Index Broad. It is anticipated that no more than 25% of the fund’s assets (determined at time of purchase) will be invested in corporate debt obligations under normal circumstances. The fund may also invest in sponsored or unsponsored American Depositary Receipts or European Depositary Receipts. While the fund may purchase securities of issuers in any foreign country, developed or developing, it is currently anticipated that the countries in which the fund may invest will include, but not be limited to, Australia, Austria, Belgium, Canada, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Japan, Korea, Luxembourg, Malaysia, Mexico, the Netherlands, New Zealand, Norway, Poland, Portugal, Singapore, South Africa, Spain, Sweden, Switzerland, United Kingdom and the United States.

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 in fixed income securities. 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. A supranational entity is an entity established or financially supported by the national governments of one or more countries to promote reconstruction or development. Examples of supranational entities include, among others, the International Bank for Reconstruction and Development (more commonly known as the World Bank), the European Economic Community, the European Investment Bank, the

Table of Contents

Inter-American Development Bank, and the Asian Development Bank. For increased safety, the fund currently anticipates that a large percentage of its assets will be invested in foreign government securities and securities of supranational entities.

With respect to U.S. Government securities, the fund may invest in securities guaranteed as to the payment of principal and interest by the U.S. Government, and those of its agencies or instrumentalities which are backed by the full faith and credit of the United States, such as Ginnie Mae. The fund also may invest in securities issued by the U.S. Government or its agencies and instrumentalities, such as Fannie Mae and Freddie Mac.

Currency considerations carry a special risk for a portfolio of international securities. The subadviser uses a purchasing power parity approach to evaluate currency risk. In this regard, the fund may actively carry on hedging activities, and may utilize a wide range of hedging 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 where currency is the U.S. dollar. Hedging and cross hedging may be used to identify value opportunities in the currency markets.

It is anticipated that the average weighted maturity of the fund will be in the three- to 10-year range. If the subadviser anticipates a declining interest rate environment, the average weighted maturity may be extended beyond 10 years. Conversely, if the subadviser anticipates a rising rate environment, the average weighted maturity may be shortened to less than three years.

The fund may invest in derivative instruments, such as futures contracts. The fund typically uses derivatives 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 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 increase the likelihood of capital gain distributions. The turnover rate may also be affected by cash requirements from redemptions of the fund’s shares.

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.

Market risk. Bond markets and the values of the securities owned by the fund 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 with all actively managed funds, the strategies of the fund’s subadviser may not achieve their desired results. The subadviser 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. These risks 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 in 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.

Debt securities risk. Bond prices generally fall when interest rates rise. Bonds with longer maturities tend to be more sensitive to this risk. Fund performance also could be affected if an issuer or guarantor of a bond held by the fund fails to make timely principal or interest payments or otherwise honor its obligations. Lower-quality bonds are considered speculative with respect to its issuer’s ability to make timely payments or otherwise honor its obligations. In addition, prices of lower-quality bonds tend to be more volatile than those of investment-grade bonds, and may fall based on bad news about the issuer, an industry or the overall economy. Mortgage- or asset-backed securities are subject to the risk that these bonds 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. Also, bonds of foreign issuers may be more volatile than those of comparable bonds from U.S. issuers, for reasons ranging from limited issuer information to the risk of political upheaval. The fund’s use of mortgage dollar rolls could cause the fund to lose money if the price of the mortgage-backed securities sold fall below the agreed upon repurchase price, or if the counterparty is unable to honor the agreement.

Interest rate risk. The fund is subject to the risk that interest rates rise and fall over time. As with any investment whose yield reflects current interest rates, the fund’s yield will change over time. During periods when interest rates are low, the fund’s yield (and total return) also may be low. When interest rates rise, bond prices usually fall which 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’s share price to fall. Although the fund invests primarily in investment-grade securities, the fund could lose money if the issuer or guarantor of a portfolio

Table of Contents

investment or the counterparty to a derivatives contract fails to make timely principal or interest payments or otherwise honor its obligations. Securities rated below investment-grade (junk bonds) involve greater risks of default or downgrade and are more volatile than investment-grade securities. Below investment-grade securities involve greater risk of price declines than investment-grade securities due to actual or perceived changes in an issuer’s creditworthiness. In addition, issuers of below investment-grade securities may be more susceptible than other issuers to economic downturns. Such securities are subject to the risk that the issuer may not be able to pay interest or dividends and ultimately to repay principal upon maturity. Discontinuation of these payments could substantially adversely affect the market value of the securities.

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. In addition, rising interest rates tend to extend the duration of certain fixed income securities, making them more sensitive to changes in interest rates. As a result, in a period of rising interest rates, the fund may exhibit additional volatility. This is known as extension risk. When interest rates decline, borrowers may pay off their fixed income securities sooner than expected. This can reduce the returns of the fund because the fund will have to reinvest that money at the lower prevailing interest rates. This is known as prepayment risk.

U.S. Government securities credit risk. The fund may invest in securities that are guaranteed by the full faith and credit of the U.S. Government. The fund may also invest in securities that are not guaranteed or insured by the U.S. Government. Issuers of securities such as Fannie Mae, Freddie Mac, the Student Loan Marketing Association and the Federal Home Loan Bank (FHLB) are supported by limited lines of credit maintained by their issuers with the U.S. Treasury. Other securities, such as obligations issued by the Federal Farm Credit Banks Funding Corporation, are supported solely by the credit of their issuer. There can be no assurance that the U.S. Government will provide financial support to securities of its agencies and instrumentalities if it is not obligated to do so under law. Therefore, the fund could lose money if an issuer or guarantor of these investments fails to make timely principal or interest payments or otherwise honor its obligations. Also, any government guarantees on securities the fund owns do not extend to shares of the fund themselves.

On September 7, 2008, the U.S. Treasury announced a federal takeover of Fannie Mae and Freddie Mac, placing the two federal instrumentalities in conservatorship. The actions of the U.S. Treasury are intended to ensure that Fannie Mae and Freddie Mac maintain a positive net worth and meet their financial obligations, preventing mandatory triggering of receivership. No assurance can be given that the U.S. Treasury initiatives will be successful.

Foreign investment risk. Investments in securities of foreign issuers involve certain risks that are more significant 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, or changes in currency exchange rates or exchange control regulations (including limitations on currency movements and exchanges). In certain countries, legal remedies available to investors may be more limited than those available with respect to investments in the United States. The securities of some foreign companies may be less liquid and at times more volatile than securities of comparable U.S. companies. A fund with foreign investments may also experience more rapid or extreme changes in value than a fund that invests solely in securities of U.S. companies because the securities markets of many foreign countries are relatively small, with a limited number of companies representing a small number of industries. There also is the risk that the cost of buying, selling, and holding foreign securities, including brokerage, tax, and custody costs, may be higher than those involved in domestic transactions.

Sovereign debt risk. Foreign government securities can involve a high degree of risk. The governmental entity that controls the repayment of sovereign debt may not be able or willing to repay the principal and/or interest when due in accordance with the terms of the debt. A governmental entity’s willingness or ability to repay principal and interest due in a timely manner may be affected by, among other factors, its cash flow situation, the extent of its foreign reserves, the availability of sufficient foreign exchange on the date a payment is due, the relative size of the debt service burden to the economy as a whole, the governmental entity’s policy toward the International Monetary Fund, and the political constraints to which a governmental entity may be subject. Governmental entities also may depend on expected disbursements from foreign governments, multilateral agencies and others to reduce principal and interest arrearages on their debt.

Emerging markets risk. Emerging markets 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, unreliable securities valuation and greater risk associated with the custody of securities. It is sometimes difficult to obtain and enforce court judgments in such countries and there is often a greater potential for nationalization and/or expropriation of assets by the government of an emerging market country. In addition, the financial stability of issuers (including governments) in emerging market countries may be more precarious than in other countries. As a result, there will tend to be an increased risk of 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.

Currency risk. As a result of its investments in securities denominated in, and/or receiving revenues in, foreign currencies, the fund will be subject to currency risk. This is the risk that those 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. In either event, the dollar value of an investment in the

fund would be adversely affected. Currency exchange rates may fluctuate in response to factors extrinsic to that country’s economy, which makes the forecasting of currency market movements extremely difficult. Currency rates in foreign countries may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates, intervention (or failure to intervene) by U.S. or foreign governments, central banks or supranational entities such as the International Monetary Fund, or by the imposition of currency controls or other political developments in the United States or abroad. These can result in losses to the fund if it is unable to deliver or receive currency or funds in settlement of obligations and could also cause hedges it has entered into to be rendered useless, resulting in full currency exposure as well as incurring transaction costs. Forward contracts on foreign currencies are not traded on exchanges; rather, a bank or dealer will act as agent or as principal in order to make or take future delivery of a specified lot of a particular currency for the fund’s account. The fund is subject to the risk of a principal’s failure, inability or refusal to perform with respect to such contracts.

Derivatives risk. Examples of derivatives are options, futures, options on futures, swaps and warrants. An option is the right to buy or sell an instrument at a specific price before a specific date. A future is an agreement to buy or sell a financial instrument at a specific price on a specific day. A swap is an agreement whereby two parties agree to exchange payment streams calculated in relation to a rate, index, instrument or certain securities and a predetermined amount. A credit default swap is an agreement in which the seller agrees to make a payment to the buyer in the event of a specified credit event in exchange for a fixed payment or series of fixed payments. A warrant is a security that gives the holder the right, but not the obligation, to subscribe for newly created equity issues of the issuing company or a related company at a fixed price either on a certain date or during a set period. Changes in the value of a warrant do not necessarily correspond to changes in the value of its underlying security. The price of a warrant may be more volatile than the price of its underlying security, and a warrant may offer greater potential for capital appreciation as well as capital loss. Warrants do not entitle a holder to dividends or voting rights with respect to the underlying security and do not represent any rights in the assets of the issuing company.

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. Certain of these risks, such as liquidity risk, credit risk, leverage risk, market risk and management risk, are discussed elsewhere in this section. The fund’s use of derivatives is also subject to lack of availability risk, valuation risk, correlation risk and tax risk. Lack of availability risk is the risk that suitable derivative transactions may not be available in all circumstances for risk management or other purposes. Valuation risk is the risk that a particular derivative may be valued incorrectly. Correlation risk is the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Tax risk is the risk that the use of derivatives may cause the fund to realize higher amounts of short-term capital gain. These risks could cause the fund to lose more than the principal amount invested.

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 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.

Liquidity risk. Liquidity risk exists when particular investments are difficult to purchase or sell. The market for certain investments may become illiquid due to specific adverse changes in the conditions of a particular issuer or under adverse market or economic conditions independent of the issuer. The fund’s investments in illiquid securities may reduce the returns of the fund because it may be unable to sell the illiquid securities at an advantageous time or price. Further, transactions in illiquid securities may entail transaction costs that are higher than those for transactions in liquid securities.

Convertible securities risk. A convertible security is a bond, debenture, note, preferred stock or other security that may be converted into or exercised for a prescribed amount of common stock at a specified time and price. Convertible securities provide an opportunity for equity participation, with the potential for a higher dividend or interest yield and lower price volatility compared to common stock. The value of a convertible security is influenced by changes in interest rates, with investment value declining as interest rates increase and increasing as interest rates decline, and the credit standing of the issuer. The price of a convertible security will also normally vary in some proportion to changes in the price of the underlying common stock because of the conversion or exercise feature.

Securities lending risk. The fund may lend its portfolio securities to brokers, dealers and other financial institutions provided a number of conditions are satisfied, including that the loan is fully collateralized. When the fund lends portfolio securities, its investment performance will continue to reflect changes in the value of the securities loaned, and the fund also will receive a fee or interest on the collateral. 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. The fund will also bear the risk of any decline in value of securities acquired with cash collateral. The fund may pay lending fees to a party arranging the loan.

Portfolio holdings

The funds may make various types of portfolio securities information available to shareholders. The funds generally post a detailed list of the securities held by each fund at www.laudus.com/prospectus (under “Portfolio Holdings”), as of the most recent calendar quarter-end. This list is generally updated approximately 30 days after the end of the calendar quarter remaining posted until at least the following calendar quarter. The funds also post in the “Analysis & Commentary” section of the website fund fact sheets containing certain summary portfolio attributes, including top ten holdings, approximately 20-30 days after the end of the calendar quarter. The funds may exclude any portion of these portfolio holdings from publication when deemed in the best interest of a fund. Further, information regarding the funds’ policy and procedures on the disclosure of portfolio securities information is available in the SAI. In addition, shareholders can learn more about the availability of portfolio securities information by calling the funds at 1-800-447-3332.

Financial highli ghts

This section provides further details about the financial history of each share class of each fund for its period of operations. Certain information reflects financial results for a single fund share. “Total return” shows the percentage that an investor in a fund would have earned or lost during a given period, assuming all distributions were reinvested. The funds’ independent registered public accounting firm, PricewaterhouseCoopers LLP, audited these figures. Their full report is included in the funds’ annual report (see back cover).
