The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate 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 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 95% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund pursues its goal by investing primarily in:

• obligations issued or guaranteed by the U.S. government or its agencies or instrumentalities;
   
• dollar-denominated obligations of foreign issuers issued in the United States;
   
• bank obligations, including those of U.S. banks and savings and loan associations and dollar-denominated obligations of U.S. subsidiaries and branches of foreign banks, such as certificates of deposit (including marketable variable rate certificates of deposit) and bankers’ acceptances;
   
• corporate debt obligations;
   
• commercial paper;
   
• obligations of supranational organizations, such as the World Bank and the European Investment Bank; and
   
• repurchase agreements.

Generally, the Fund acquires obligations that mature within two years from the date of settlement. The Fund has a non-fundamental investment policy that, under normal circumstances, it will invest at least 80% of its net assets in fixed income securities issued in the U.S.

With respect to corporate debt securities (e.g., bonds and debentures), the Fund generally invests in nonconvertible securities that are issued by U.S. issuers and dollar-denominated obligations of foreign issuers issued in the U.S. Such securities must be issued by entities whose commercial paper is rated Prime 1 by Moody’s Investors Service, Inc. (“Moody’s”), at least A1 or better by Standard & Poor’s, a division of The McGraw-Hill Companies, Inc. (“S&P”), or F1 or better by Fitch Ratings Ltd (“Fitch”). If the issuer’s commercial paper is unrated, then the debt security to be purchased must be rated at least AA by S&P, Aa2 by Moody’s or AA by Fitch. If there is neither a commercial paper rating nor a rating of the debt security to be purchased, then the Sub-Adviser must determine that the debt security to be purchased is of comparable quality to equivalent issues of the same issuer rated at least AA by S&P, Aa2 by Moody’s or AA by Fitch.

The Fund may invest in U.S. Treasury bonds, bills and notes and obligations of federal agencies or instrumentalities. Some U.S. government obligations that the Fund may invest in, such as Treasury bills, notes and bonds and securities guaranteed by the Government National Mortgage Association, are supported by the full faith and credit of the United States, while others are not such as those of or guaranteed by the Federal Home Loan Banks, Federal Home Loan Mortgage Corporation and Federal National Mortgage Association.

The Fund will invest more than 25% of its total assets in dollar-denominated obligations of U.S. banks and U.S. subsidiaries and branches of foreign banks and bank holding companies when the yield to maturity on these investments exceeds the yield to maturity on all other eligible portfolio investments of similar quality for a period of five consecutive days during which the New York Stock Exchange (“NYSE”) is open for trading. To determine that yields on dollar-denominated bank obligations are more attractive than yields on all other eligible portfolio investments of similar quality, the Sub-Adviser will examine the yield to maturity information for available fixed income securities of other industry sectors as compared to bank obligations after eliminating individual securities in each industry sector that would not be eligible for investment by the Fund. If the yield to maturity for eligible bank obligations is higher than that of eligible portfolio investments of similar quality of all other industry sectors, investments in bank obligations will be considered to have a yield that generally exceeds the yield on other eligible investments as a group. When investments in such bank obligations exceed 25% of the Fund’s total assets, the Fund will be considered to be concentrating its investments in the banking industry.

The types of bank and bank holding company obligations in which the Fund may invest include: dollar-denominated certificates of deposit, bankers’ acceptances, commercial paper, repurchase agreements and other debt obligations that mature within two years of the date of settlement, provided that such obligations meet the Fund’s established credit rating or other criteria. Commercial paper must be rated A1 or better by S&P, Prime 1 by Moody’s, F1 or better by Fitch or, if not rated, issued by a corporation having an outstanding unsecured debt issue rated Aaa by Moody’s, AAA by S&P or AAA by Fitch. Bank certificates of deposit will only be acquired from banks having assets in excess of $1 billion. The Fund will not enter into repurchase agreements with a bank unless the bank has at least $1 billion in assets and is approved by the Investment Committee of the Sub-Adviser.

All ratings described above apply at the time of investment.

Risk [Heading]

rr_RiskHeading

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund’s share price and yield may change daily because of changes in interest rates and other market conditions and factors. Therefore, you may lose money if you invest in the Fund.

The principal risks that apply to the Fund are:

• Market Risk: The value of the securities in which the Fund invests may go up or down in response to the prospects of individual issuers, general economic or market conditions, and/or investor behavior that leads investors’ perceptions of value (as reflected in the price of the security) to diverge from fundamental value.
   
• Interest Rate and Related Risks: Generally, when market interest rates rise, the value of debt securities declines, and vice versa. Investing in such securities means that the Fund’s net asset value will tend to decline if market interest rates rise. Interest rate risk is generally greater for fixed-income securities with longer maturities or durations. During periods of rising interest rates, the average life of certain types of securities in which the Fund invests may be extended because of slower than expected principal payments. This may lock in a below-market interest rate, increase the security’s duration (i.e., the estimated period until the principal and interest are paid in full) and reduce the value of the security. This is known as extension risk. During periods of declining interest rates, issuers of certain securities may exercise their option to prepay principal earlier than scheduled, forcing the Fund to reinvest in lower yielding securities. This is known as call or prepayment risk.
   
• Credit Risk: It is possible that some issuers or guarantors may default on debt securities held by the Fund, or there could be defaults on repurchase agreements held by the Fund. Also, an issuer may suffer adverse changes in financial condition that could result in a downgrade in credit rating leading to greater volatility in the price of the security and, consequently, in the price of shares of the Fund. A change in the credit rating of a bond can also affect the bond’s liquidity and make it more difficult for the Fund to sell. Credit ratings are only the opinions of the rating agencies issuing them, do not purport to reflect the risk of fluctuations in market value and are not guarantees as to the payment of interest and repayment of principal.
   
• Income Risk: Because the Fund can only distribute what it earns, the Fund’s distributions to shareholders may decline when prevailing interest rates fall or if the Fund experiences defaults on debt securities it holds.
   
• U.S. Government Securities Risk: Although the Fund may invest in securities that carry U.S. government guarantees, these guarantees do not extend to shares of the Fund itself and do not guarantee the market price of the securities. Furthermore, not all securities issued by the U.S. government and its agencies and instrumentalities are backed by the full faith and credit of the U.S. Treasury. There is no guarantee that the U.S. government will support securities not backed by its full faith and credit.
   
• Banking Concentration Risk: To the extent the Fund invests more than 25% of its total assets in bank and bank holding company obligations, such banking industry investments would link the performance of the Fund to changes in the performance of the banking industry generally. Banks are subject to extensive government regulation that may affect the scope of their activities, their profitability, the prices that they can charge and the amount of capital that they must maintain. In addition, unstable interest rates can have a disproportionate effect on the banking industry; banks whose securities the Fund may purchase may themselves have concentrated portfolios of loans or investments that make them vulnerable to economic conditions that affect that industry.
   
• Recent Market Conditions: The financial crisis in the U.S. and global economies over the past several years, including the European sovereign debt and banking crises, has resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign, and in the net asset values of many mutual funds, including to some extent the Fund. It is uncertain how long these conditions will continue. These market conditions have resulted, and may continue to result, in fixed income instruments experiencing unusual liquidity issues, increased price volatility and, in some cases, credit downgrades and increased likelihood of default. In addition, global economies and financial markets are becoming increasingly interconnected, which increases the possibilities that conditions in one country or region might adversely impact issuers in a different country or region. The severity or duration of these conditions may also be affected by policy changes made by governments or quasi-governmental organizations.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund pursues its goal by investing primarily in:

• obligations issued or guaranteed by the U.S. and foreign governments of developed countries or their agencies or instrumentalities;
   
• obligations of supranational organizations, such as the World Bank and the European Investment Bank;
   
• obligations of other U.S. and foreign issuers including:

• corporate debt obligations;
   
• commercial paper;
   
• bank obligations; and
   
• repurchase agreements.

The Fund primarily invests in fixed income securities that mature within five years from the date of settlement. The Fund has a non-fundamental investment policy that, under normal circumstances, it will invest at least 80% of its net assets in fixed income securities.

The Fund may invest in U.S. Treasury bonds, bills and notes and obligations of federal agencies or instrumentalities. Some U.S. government obligations in which the Fund may invest, such as Treasury bills, notes and bonds and securities guaranteed by the Government National Mortgage Association, are supported by the full faith and credit of the United States, while others are not such as those of or guaranteed by the Federal Home Loan Banks, Federal Home Loan Mortgage Corporation and Federal National Mortgage Association.

The Fund may also invest in fixed income securities issued or guaranteed by foreign governments or their agencies or instrumentalities such as bills, notes, bonds and other debt securities and may invest in debt securities of supranational organizations. With respect to such securities, the Fund will generally invest in fixed income securities of issuers whose short-term debt rating is rated Prime 1 by Moody’s, at least A1 or better by S&P or F1 or better by Fitch. If the issuer does not have a short-term debt rating, then the debt security to be purchased must be rated at least AA by S&P, Aa2 by Moody’s or AA by Fitch. If there is neither a short-term debt rating nor a rating of the debt security to be purchased, then the Sub-Adviser must determine that the debt security to be purchased is of comparable quality to equivalent issues of the same issuer rated at least AA by S&P, Aa2 by Moody’s or AA by Fitch.

With respect to corporate debt securities (e.g., bonds and debentures), the Fund generally invests in nonconvertible securities that are issued by U.S. and foreign issuers whose commercial paper is rated Prime 1 by Moody’s, at least A1 or better by S&P or F1 or better by Fitch. If the issuer’s commercial paper is unrated, then the debt security to be purchased must be rated at least AA by S&P, Aa2 by Moody’s or AA by Fitch. If there is neither a commercial paper rating nor a rating of the debt security to be purchased, then the Sub-Adviser must determine that the debt security to be purchased is of comparable quality to equivalent issues of the same issuer rated at least AA by S&P, Aa2 by Moody’s or AA by Fitch.

The types of bank and bank holding company obligations in which the Fund may invest include, without limitation: certificates of deposit (including marketable variable rate certificates of deposit), bankers’ acceptances, commercial paper, repurchase agreements and other debt obligations that mature within five years of the date of settlement, provided such obligations meet the Fund’s established credit rating or other criteria. Commercial paper must be rated A1 or better by S&P, Prime 1 by Moody’s, F1 or better by Fitch or, if not rated, issued by a corporation having an outstanding unsecured debt issue rated Aaa by Moody’s, AAA by S&P or AAA by Fitch. Bank certificates of deposit will only be acquired from banks having assets in excess of $1 billion. The Fund will not enter into repurchase agreements with a bank unless the bank has at least $1 billion in assets and is approved by the Investment Committee of the Sub-Adviser.

All ratings described above apply at the time of investment.

These securities may be denominated in U.S. dollars as well as other currencies, including the Euro. The Fund invests in foreign issuers in countries with developed markets designated by the Investment Committee of the Sub-Adviser from time to time. As of the date of this Prospectus, the Fund is authorized to invest in foreign issuers in Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Japan, Luxembourg, the Netherlands, New Zealand, Norway, Singapore, Sweden, Switzerland and the United Kingdom. This list of authorized countries is subject to change. The Sub-Adviser will determine when and whether to invest in countries that have been authorized, depending on a number of factors, such as asset availability in the Fund and characteristics of each country’s market. Under normal market conditions, the Fund will invest (1) at least 40% (and up to 100%) of its total assets in the securities of foreign issuers and (2) in issuers organized or having a majority of their assets in, or deriving a majority of their operating income from, at least three different countries, one of which may be the United States. The actual number of countries represented in the Fund’s portfolio may vary over time.

The Fund attempts to maximize its total return by allocating assets among countries depending on prevailing interest rates while targeting the duration of the Fund’s benchmark index. For example, the Sub-Adviser may sell a security denominated in one currency and buy a security denominated in a different currency depending on market conditions. The Fund will invest no more than 50% of its total assets in securities denominated in U.S. dollars at the time of purchase.

The Fund may enter into forward foreign currency exchange contracts to hedge foreign currency risks. The Fund may also lend its portfolio securities to generate additional income.

Strategy Portfolio Concentration [Text]

rr_StrategyPortfolioConcentration

The Fund has a non-fundamental investment policy that, under normal circumstances, it will invest at least 80% of its net assets in fixed income securities.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund’s share price and yield may change daily because of changes in interest rates and other market conditions and factors. Therefore, you may lose money if you invest in the Fund.

The principal risks that apply to the Fund are:

• Market Risk: The value of the securities in which the Fund invests may go up or down in response to the prospects of individual issuers, general economic or market conditions, and/or investor behavior that leads investors’ perceptions of value (as reflected in the price of the security) to diverge from fundamental value.
   
• Interest Rate and Related Risks: Generally, when market interest rates rise, the value of debt securities declines, and vice versa. Investing in such securities means that the Fund’s net asset value will tend to decline if market interest rates rise. Interest rate risk is generally greater for fixed-income securities with longer maturities or durations. During periods of rising interest rates, the average life of certain types of securities in which the Fund invests may be extended because of slower than expected principal payments. This may lock in a below-market interest rate, increase the security’s duration (i.e., the estimated period until the principal and interest are paid in full) and reduce the value of the security. This is known as extension risk. During periods of declining interest rates, issuers of certain securities may exercise their option to prepay principal earlier than scheduled, forcing the Fund to reinvest in lower yielding securities. This is known as call or prepayment risk.
   
• Credit Risk: It is possible that some issuers or guarantors may default on debt securities held by the Fund, or there could be defaults on repurchase agreements held by the Fund. Also, an issuer may suffer adverse changes in financial condition that could result in a downgrade in credit rating leading to greater volatility in the price of the security and, consequently, in the price of shares of the Fund. A change in the credit rating of a bond can also affect the bond’s liquidity and make it more difficult for the Fund to sell. Credit ratings are only the opinions of the rating agencies issuing them, do not purport to reflect the risk of fluctuations in market value and are not guarantees as to the payment of interest and repayment of principal.
   
• Income Risk: Because the Fund can only distribute what it earns, the Fund’s distributions to shareholders may decline when prevailing interest rates fall or if the Fund experiences defaults on debt securities it holds.
   
• Foreign Securities and Currency Risk: Foreign securities involve risks in addition to those associated with comparable U.S. securities. Investments in foreign securities are subject to fluctuations in currency exchange rates, which may negatively affect the value of the Fund’s portfolio. Additional risks may include exposure to less developed or less efficient trading markets; social, political or economic instability; currency controls or redenomination; changes in tax policy; high transaction costs; settlement, custodial or other operational risks; and less stringent accounting, auditing, financial reporting, and legal standards and practices. As a result, foreign securities can fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities.
   
• Foreign Government and Supranational Organization Obligations Risk: By investing in foreign government obligations, the Fund will be exposed to the direct or indirect consequences of political, social, and economic changes in various countries. The Fund may have limited legal recourse in the event of a default with respect to foreign government and supranational organization obligations it holds.
   
• Hedging Risk: Forward foreign currency exchange contracts may be used to hedge foreign currency risk. Hedging tends to limit any potential gain that may be realized if the value of the Fund’s portfolio holdings increases because of currency fluctuations. In addition, hedging may increase the Fund’s expenses. There is also a risk that a forward foreign currency exchange contract intended as a hedge may not perform as intended, in which case the Fund may not be able to minimize the effects of foreign currency fluctuations and may suffer a loss.
   
• Securities Lending Risk: Securities lending involves possible delay in recovery of the securities or possible loss of rights in the collateral should the borrower fail financially. As a result, the value of the Fund shares may fall. The value of the Fund shares could also fall if a loan is called and the Fund is required to liquidate reinvested collateral at a loss or if the Fund is unable to reinvest cash collateral at rates which exceed the costs involved.
   
• European Economic Risk: Recently, the European financial markets have been negatively impacted by rising government debt levels; possible default on or restructuring of sovereign debt in several European countries, including Greece, Ireland, Italy, Portugal and Spain; and economic downturns. A European country’s default or debt restructuring would adversely affect the holders of the country’s debt and sellers of credit default swaps linked to the country’s creditworthiness and could negatively impact global markets more generally. Recent events in Europe have adversely affected the euro’s exchange rate and value and may continue to impact the economies of every European country.
   
• U.S. Government Securities Risk: Although the Fund may invest in securities that carry U.S. government guarantees, these guarantees do not extend to shares of the Fund itself and do not guarantee the market price of the securities. Furthermore, not all securities issued by the U.S. government and its agencies and instrumentalities are backed by the full faith and credit of the U.S. Treasury. There is no guarantee that the U.S. government will support securities not backed by its full faith and credit.
   
• Recent Market Conditions: The financial crisis in the U.S. and global economies over the past several years, including the European sovereign debt and banking crises, has resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign, and in the net asset values of many mutual funds, including to some extent the Fund. It is uncertain how long these conditions will continue. These market conditions have resulted, and may continue to result, in fixed income instruments experiencing unusual liquidity issues, increased price volatility and, in some cases, credit downgrades and increased likelihood of default. In addition, global economies and financial markets are becoming increasingly interconnected, which increases the possibilities that conditions in one country or region might adversely impact issuers in a different country or region. The severity or duration of these conditions may also be affected by policy changes made by governments or quasi-governmental organizations.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund pursues its goal by generally selecting from all common stocks that are traded on a principal U.S. exchange or on the over-the-counter market in the United States. As of the date of this Prospectus, the Sub-Adviser has narrowed the target universe of stocks to securities of companies whose market capitalizations generally are either in the highest 96% of total market capitalizationor companies whose market capitalizations are larger than the 1,500^th largest U.S. company, whichever results in the higher market capitalization threshold. Under the Sub-Adviser’s market capitalization guidelines described above, as of August 31, 2012, the target universe was defined by the market capitalization of the 96% of total market capitalization, which was approximately $1,069 million or above. This dollar amount will change due to market conditions. The Fund has a non-fundamental investment policy that, under normal circumstances, it will invest at least 80% of its net assets in U.S. securities.

The Fund also invests less than 5% of its total assets in the U.S. Micro Cap Portfolio, a portfolio of DFA Investment Dimensions Group Inc., a separate registered investment company. The Sub-Adviser is also the adviser of the U.S. Micro Cap Portfolio. The U.S. Micro Cap Portfolio generally will purchase a broad and diverse group of the common stocks of micro cap companies traded on a principal U.S. exchange or the over-the-counter market.

The Fund may lend its portfolio securities to generate additional income.

The share price of the Fund may change daily based on market conditions and other factors. Therefore, you may lose money if you invest in the Fund.

The principal risks that apply to the Fund are:

• Market Risk: The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, general economic or market conditions, and/or investor behavior that leads investors’ perceptions of value (as reflected in the stock price) to diverge from fundamental value.
   
• Large Company Stock Risk: Larger, more established companies may be unable to respond quickly to competitive challenges, such as changes in technology and consumer tastes.
   
• Medium-Size Company Stock Risk: Stocks of medium-size companies are usually more sensitive to adverse business developments and economic, political, regulatory and market factors than stocks of larger companies, and the prices of stocks of medium-size companies may be more volatile.
   
• Small Company Stock Risk: The stocks of small companies may have more risks than those of larger companies. Small companies often have narrower markets and more limited managerial and financial resources than larger, more established companies. As a result, they may be more sensitive to changing economic conditions, which could increase the volatility of the Fund’s portfolio. In addition, small company stocks typically are traded in lower volume, making them more difficult to purchase or sell. Generally, the smaller the company size, the greater these risks.
   
• Securities Lending Risk: Securities lending involves possible delay in recovery of the securities or possible loss of rights in the collateral should the borrower fail financially. As a result, the value of the Fund shares may fall. The value of the Fund shares could also fall if a loan is called and the Fund is required to liquidate reinvested collateral at a loss or if the Fund is unable to reinvest cash collateral at rates which exceed the costs involved.

The Fund pursues its goal by generally investing in a target universe consisting of common stocks of large and mid cap U.S. companies traded on a principal U.S. exchange or on the over-the-counter market in the United States that the Sub-Adviser believes are “value” stocks at the time of purchase. The Sub-Adviser considers value stocks primarily to be those of companies with high book values (values that are derived from a company’s balance sheet) in relation to their market values (values that are derived by multiplying the market price per share of a company’s stock by the number of outstanding shares of that stock). In measuring value, the Sub-Adviser may also consider such factors as price-to-cash flow or price-to-earnings ratios, economic conditions and developments in the company’s industry. The criteria used for assessing value are subject to change from time to time. As of the date of this Prospectus, the Sub-Adviser considers large and mid cap companies to be companies whose market capitalizations generally are either in the highest 90% of total market capitalization or companies whose market capitalizations are larger than the 1,000^th largest U.S. company, whichever results in the higher market capitalization threshold. Under the Sub-Adviser’s market capitalization guidelines described above, as of August 31, 2012, the market capitalization of a large or mid cap company was defined by the market capitalization of a company in the highest 90% of total market capitalization, which was approximately $2,673 million or above. This dollar amount will change due to market conditions. The Fund has a non-fundamental investment policy that, under normal circumstances, it will invest at least 80% of its net assets in U.S. securities.

The Fund may lend its portfolio securities to generate additional income.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The share price of the Fund may change daily based on market conditions and other factors. Therefore, you may lose money if you invest in the Fund.

The principal risks that apply to the Fund are:

• Market Risk: The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, general economic or market conditions, and/or investor behavior that leads investors’ perceptions of value (as reflected in the stock price) to diverge from fundamental value.
   
• Value Stock Risk: A value stock may not reach what the Sub-Adviser believes is its full market value, or its intrinsic value may go down. In addition, value stocks may underperform when the market favors growth stocks over value stocks.
   
• Large Company Stock Risk: Larger, more established companies may be unable to respond quickly to competitive challenges, such as changes in technology and consumer tastes.
   
• Medium-Size Company Stock Risk: Stocks of medium-size companies are usually more sensitive to adverse business developments and economic, political, regulatory and market factors than stocks of larger companies, and the prices of stocks of medium-size companies may be more volatile. The Fund may experience difficulty in purchasing or selling securities of medium-size companies at the desired time and price.
   
• Securities Lending Risk: Securities lending involves possible delay in recovery of the securities or possible loss of rights in the collateral should the borrower fail financially. As a result, the value of the Fund shares may fall. The value of the Fund shares could also fall if a loan is called and the Fund is required to liquidate reinvested collateral at a loss or if the Fund is unable to reinvest cash collateral at rates which exceed the costs involved.
   
• Recent Market Conditions: The financial crisis in the U.S. and global economies over the past several years, including the European sovereign debt and banking crises, has resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign, and in the net asset values of many mutual funds, including to some extent the Fund. It is uncertain how long these conditions will continue. In addition, global economies and financial markets are becoming increasingly interconnected, which increases the possibilities that conditions in one country or region might adversely impact issuers in a different country or region. The severity or duration of these conditions may also be affected by policy changes made by governments or quasi-governmental organizations.

Small companies often have narrower markets and more limited managerial and financial resources than larger, more established companies. As a result they may be more sensitive to changing economic conditions, which could increase the volatility of the Fund’s portfolio. In addition, small company stocks typically are traded in lower volume, making them more difficult to purchase or sell. Generally, the smaller the company size, the greater these risks.

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund pursues its goal by generally investing in a target universe consisting of securities of large cap non-U.S. companies that the Sub-Adviser believes are “value” stocks at the time of purchase. The Sub-Adviser considers value stocks primarily to be those of companies with high book values (values that are derived from a company’s balance sheet) in relation to their market values (values that are derived by multiplying the market price per share of a company’s stock by the number of outstanding shares of that stock). In measuring value, the Sub-Adviser may also consider such factors as price-to-cash flow or price-to-earnings ratios, economic conditions and developments in the company’s industry. The criteria used for assessing value are subject to change from time to time.

The Fund invests in companies in countries with developed markets designated by the Investment Committee of the Sub-Adviser as approved markets from time to time. As of the date of this Prospectus, the Fund is authorized to invest in the stocks of large cap companies in Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Greece, Hong Kong, Ireland, Israel, Italy, Japan, the Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland and the United Kingdom. This list of authorized countries is subject to change. Under normal market conditions, the Sub-Adviser intends to invest in companies organized or having a majority of their operating income from sources in at least three non-U.S. countries.

The Sub-Adviser determines company size on a country- or region-specific basis and based primarily on market capitalization. In the countries or regions authorized for investment, the Sub-Adviser first ranks eligible companies listed on selected exchanges based on the companies’ market capitalizations. The Sub-Adviser then determines the universe of eligible stocks by defining the minimum market capitalization of a large cap company that may be purchased by the Fund with respect to each country or region. As of August 31, 2012, the lowest minimum market capitalization of a large cap company in any country or region in which the Fund invests was $1,443 million. This threshold will vary by country and region and will change with market conditions.

The Fund intends to purchase securities within each authorized country using a market capitalization weighted approach. The Sub-Adviser, using this approach and its judgment, will seek to set country weights based on the relative market capitalization of eligible large cap non-U.S. companies within each country.

The Fund may lend its portfolio securities to generate additional income.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The share price of the Fund may change daily based on market conditions and other factors. Therefore, you may lose money if you invest in the Fund.

The principal risks that apply to the Fund are:

• Market Risk: The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, general economic or market conditions, and/or investor behavior that leads investors’ perceptions of value (as reflected in the stock price) to diverge from fundamental value.
   
• Foreign Securities and Currency Risk: Foreign securities involve risks in addition to those associated with comparable U.S. securities. Investments in foreign securities are subject to fluctuations in currency exchange rates, which may negatively affect the value of the Fund’s portfolio. Additional risks may include exposure to less developed or less efficient trading markets; social, political or economic instability; currency controls or redenomination; changes in tax policy; high transaction costs; settlement, custodial or other operational risks; and less stringent accounting, auditing, financial reporting, and legal standards and practices. As a result, foreign securities can fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities.
   
• European Economic Risk: Recently, the European financial markets have been negatively impacted by rising government debt levels; possible default on or restructuring of sovereign debt in several European countries, including Greece, Ireland, Italy, Portugal and Spain; and economic downturns. A European country’s default or debt restructuring would adversely affect the holders of the country’s debt and sellers of credit default swaps linked to the country’s creditworthiness and could negatively impact global markets more generally. Recent events in Europe have adversely affected the euro’s exchange rate and value and may continue to impact the economies of every European country.
   
• Large Company Stock Risk: Larger, more established companies may be unable to respond quickly to competitive challenges, such as changes in technology and consumer tastes.
   
• Value Stock Risk: A value stock may not reach what the Sub-Adviser believes is its full market value, or its intrinsic value may go down. In addition, value stocks may underperform when the market favors growth stocks over value stocks.
   
• Securities Lending Risk: Securities lending involves possible delay in recovery of the securities or possible loss of rights in the collateral should the borrower fail financially. As a result, the value of the Fund shares may fall. The value of the Fund shares could also fall if a loan is called and the Fund is required to liquidate reinvested collateral at a loss or if the Fund is unable to reinvest cash collateral at rates which exceed the costs involved.
   
• Recent Market Conditions: The financial crisis in the U.S. and global economies over the past several years, including the European sovereign debt and banking crises, has resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign, and in the net asset values of many mutual funds, including to some extent the Fund. It is uncertain how long these conditions will continue. In addition, global economies and financial markets are becoming increasingly interconnected, which increases the possibilities that conditions in one country or region might adversely impact issuers in a different country or region. The severity or duration of these conditions may also be affected by policy changes made by governments or quasi-governmental organizations.

A mutual fund generally pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when mutual fund shares are held in a taxable account. The Fund does not pay transaction costs when buying and selling shares of the DFA Portfolio and the DFA Portfolio does not pay transaction costs when buying and selling shares of the Underlying Funds (as defined below); however, each of the Underlying Funds pay transaction costs when buying and selling securities for its portfolio. The transaction costs incurred by the Underlying Funds, which are not reflected in Annual Fund Operating Expenses or in the expense example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 0% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Instead of buying securities directly, the Fund invests substantially all of its assets in the DFA Portfolio, which has the same investment objective and investment policies as the Fund. The DFA Portfolio seeks to provide investors with access to securities portfolios consisting of a broad range of equity securities of primarily small Japanese, United Kingdom, European (including the Mediterranean), Asia Pacific and Canadian companies. The DFA Portfolio invests substantially all of its assets in: The Japanese Small Company Series (the “Japanese Series”), The United Kingdom Small Company Series (the “United Kingdom Series”), The Continental Small Company Series (the “Continental Series”), The Asia Pacific Small Company Series (the “Asia Pacific Series”) and The Canadian Small Company Series (the “Canadian Series”) (each an “Underlying Fund” and together, the “Underlying Funds”), each of which is a series of The DFA Investment Trust Company. Each Underlying Fund invests in small companies using a market capitalization weighted approach in each country or region designated by the Sub-Adviser as an approved market for investment. The DFA Portfolio also may have some exposure to small cap equity securities associated with other countries or regions. As a non-fundamental policy, under normal circumstances, the Fund, through its investments in the DFA Portfolio and, indirectly, the Underlying Funds, will invest at least 80% of its net assets in securities of small companies.

As of August 31, 2012, the DFA Portfolio invested its assets in the Underlying Funds within the following ranges (expressed as a percentage of the DFA Portfolio’s assets):

Underlying Fund	Investment Range
Japanese Series		10% - 35%
United Kingdom Series		10% - 30%
Continental Series		25% - 50%
Asia Pacific Series		0% - 25%
Canadian Series		0% - 20%

The allocation of the assets of the DFA Portfolio to be invested in the Underlying Funds will be determined by the Sub-Adviser on at least a semi-annual basis. The Underlying Funds invest in countries that the Sub-Adviser views as developed market countries and will not invest in emerging market countries. Each Underlying Fund may lend its portfolio securities to generate additional income.

The DFA Portfolio and the Underlying Funds are advised by the Sub-Adviser. For as long as the Fund invests substantially all of its assets in the DFA Portfolio, the Sub-Adviser will not receive any sub-advisory fee from the Fund for its sub-advisory services. The Sub-Adviser receives an administration fee and an investment advisory fee from its management of the DFA Portfolio and the Underlying Funds. The Sub-Adviser has agreed to this fee arrangement in order to prevent duplication of advisory fees to the Sub-Adviser.

The Fund may withdraw its investment in the DFA Portfolio at any time if the Fund’s Board of Trustees determines that it is in the best interest of the Fund and its shareholders to do so. If this happens, the Fund’s assets either will be invested in another mutual fund or will be invested directly according to the investment policies and restrictions described in this Prospectus.

Risk [Heading]

rr_RiskHeading

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The share price of the Fund may change daily based on market conditions and other factors. Therefore, you may lose money if you invest in the Fund.

The principal risks that apply to the Fund are:

• Fund of Funds Risk: The investment performance of the Fund is affected by the investment performance of the DFA Portfolio and, indirectly, the investment performance of the Underlying Funds. The ability of the Fund to achieve its investment objective depends on the ability of the DFA Portfolio and the Underlying Funds to meet their investment objectives and on the Sub-Adviser’s decisions regarding the allocation of the DFA Portfolio’s assets among the Underlying Funds. There can be no assurance that the investment objective of the Fund, the DFA Portfolio or any Underlying Fund will be achieved. Through its investment in the DFA Portfolio and, indirectly, the Underlying Funds, the Fund is subject to the risks of the Underlying Funds’ investments. The risks of the Underlying Funds’ investments are described below. Duplication of expenses is a risk when a fund invests in other investment companies.
   
• Market Risk: The value of the securities in which the Underlying Funds invest may go up or down in response to the prospects of individual companies, general economic or market conditions, and/or investor behavior that leads investors’ perceptions of value (as reflected in the stock price) to diverge from fundamental value. 
   
• Small Company Stock Risk: The stocks of small companies may have more risks than those of larger companies. Small companies often have narrower markets and more limited managerial and financial resources than larger, more established companies. As a result they may be more sensitive to changing economic conditions, which could increase the volatility of the Underlying Funds’ portfolios. In addition, small company stocks typically are traded in lower volume, making them more difficult to purchase or sell. Generally, the smaller the company size, the greater these risks.
   
• Foreign Securities and Currency Risk: Foreign securities involve risks in addition to those associated with comparable U.S. securities. Investments in foreign securities are subject to fluctuations in currency exchange rates, which may negatively affect the value of the Fund’s portfolio. Additional risks may include exposure to less developed or less efficient trading markets; social, political or economic instability; currency controls or redenomination; changes in tax policy; high transaction costs; settlement, custodial or other operational risks; and less stringent accounting, auditing, financial reporting, and legal standards and practices. As a result, foreign securities can fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities.
   
• Securities Lending Risk: Securities lending involves possible delay in recovery of the securities or possible loss of rights in the collateral should the borrower fail financially. As a result, the value of the Underlying Fund shares (and, indirectly, the Fund shares) may fall. The value of the Underlying Fund shares (and, indirectly, the Fund shares) could also fall if a loan is called and the Underlying Fund is required to liquidate reinvested collateral at a loss or if the Underlying Fund is unable to reinvest cash collateral at rates which exceed the costs involved.
   
• European Economic Risk: Recently, the European financial markets have been negatively impacted by rising government debt levels; possible default on or restructuring of sovereign debt in several European countries, including Greece, Ireland, Italy, Portugal and Spain; and economic downturns. A European country’s default or debt restructuring would adversely affect the holders of the country’s debt and sellers of credit default swaps linked to the country’s creditworthiness and could negatively impact global markets more generally. Recent events in Europe have adversely affected the euro’s exchange rate and value and may continue to impact the economies of every European country. 
   
• Recent Market Conditions: The financial crisis in the U.S. and global economies over the past several years, including the European sovereign debt and banking crises, has resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign, and in the net asset values of many mutual funds, including to some extent the Fund. It is uncertain how long these conditions will continue. In addition, global economies and financial markets are becoming increasingly interconnected, which increases the possibilities that conditions in one country or region might adversely impact issuers in a different country or region. The severity or duration of these conditions may also be affected by policy changes made by governments or quasi-governmental organizations.

Strategy Narrative [Text Block]

The Fund pursues its goal by purchasing a broad and diverse group of securities of companies in emerging markets, which may include frontier markets (i.e., emerging market countries in an earlier stage of development). The Fund intends to purchase companies with small, medium and large market capitalizations in their respective markets that the Sub-Adviser considers to be “value” stocks.

The Fund seeks to achieve its goal by investing in companies in countries designated by the Investment Committee of the Sub-Adviser from time to time as approved markets. As of the date of this Prospectus, the Fund is authorized to invest in the following approved markets: Brazil, Chile, China, Colombia, the Czech Republic, Hungary, India, Indonesia, Malaysia, Mexico, the Philippines, Poland, Russia, South Africa, South Korea, Taiwan, Thailand, and Turkey. The Sub-Adviser may authorize other countries for investment in the future in addition to the approved markets listed above. In addition, the Fund may also continue to hold securities associated with countries that are not listed above as approved markets but had been authorized for investment in the past and may reinvest distributions received in connection with such existing investments in such previously approved countries. As a non-fundamental policy, under normal circumstances, the Fund will invest at least 80% of its net assets in emerging markets investments that are approved market securities.

The Fund seeks to purchase securities of small, medium and large companies that are representative of broad market coverage within each approved market. The Fund’s definition of what constitutes a small, medium and large company varies across countries and is based primarily on market capitalization. In each approved market, the companies listed on selected exchanges are ranked based upon their market capitalizations. The minimum market capitalization for a company in that country is then defined. As of August 31, 2012, Mexico had the highest market capitalization threshold for investment of approximately $1,634 million; and Hungary had the lowest market capitalization threshold for investment of approximately $236 million. These dollar amounts will change due to market conditions.

In assessing value, the Sub-Adviser primarily considers a security’s book value (value that is derived from a company’s balance sheet) in relation to its market value (value that is derived by multiplying the market price per share of a company’s stock by the number of outstanding shares of that stock). However, the Sub-Adviser may also consider factors such as price-to-cash flow or price-to-earnings ratios, as well as economic conditions and developments in the company’s industry. The criteria the Sub-Adviser uses for assessing value are subject to change from time to time. The Fund may not invest in certain companies or approved markets for reasons that include constraints imposed within approved markets (e.g., restrictions on purchases by foreigners), and the Fund’s policy not to invest more than 25% of its assets in any one industry.

Strategy Portfolio Concentration [Text]

rr_StrategyPortfolioConcentration

As a non-fundamental policy, under normal circumstances, the Fund will invest at least 80% of its net assets in emerging markets investments that are approved market securities.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The share price of the Fund may change daily based on market conditions and other factors. Therefore, you may lose money if you invest in the Fund.

The principal risks that apply to the Fund are:

• Market Risk: The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, general economic or market conditions, and/or investor behavior that leads investors’ perceptions of value (as reflected in the stock price) to diverge from fundamental value.
   
• Emerging Markets Risk: Investing in emerging market countries involves risks in addition to those generally associated with investing in developed foreign countries. Securities issued in these countries may be more volatile and less liquid than securities issued in foreign countries with more developed economies or markets. Numerous emerging market countries have experienced serious, and frequently continuing, economic and political problems. Foreigners are often limited in their ability to invest in, and withdraw assets from, these markets.
   
• Value Stock Risk: A value stock may not reach what the Sub-Adviser believes is its full market value, or its intrinsic value may go down. In addition, value stocks may underperform when the market favors growth stocks over value stocks.
   
• Large Company Stock Risk: Larger, more established companies may be unable to respond quickly to competitive challenges, such as changes in technology and consumer tastes.
   
• Medium-Size Company Stock Risk: Stocks of medium-size companies are usually more sensitive to adverse business developments and economic, political, regulatory and market factors than stocks of large companies, and the prices of stocks of medium-size companies may be more volatile.
   
• Small Company Stock Risk: The stocks of small companies may have more risks than those of larger companies. Small companies often have narrower markets and more limited managerial and financial resources than larger, more established companies. As a result, they may be more sensitive to changing economic conditions, which could increase the volatility of the Fund’s portfolio. In addition, small company stocks typically are traded in lower volume, making them more difficult to purchase or sell. Generally, the smaller the company size, the greater these risks.
   
• Foreign Securities and Currency Risk: Foreign securities involve risks in addition to those associated with comparable U.S. securities. Investments in foreign securities are subject to fluctuations in currency exchange rates, which may negatively affect the value of the Fund’s portfolio. Additional risks may include exposure to less developed or less efficient trading markets; social, political or economic instability; currency controls or redenomination; nationalization or expropriation of assets; changes in tax policy; high transaction costs; settlement, custodial or other operational risks; and less stringent accounting, auditing, financial reporting, and legal standards and practices. In addition, key information about the issuer, the markets or the local government or economy may be unavailable, incomplete or inaccurate. As a result, foreign securities can fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities.

• Recent Market Conditions: The financial crisis in the U.S. and global economies over the past several years, including the European sovereign debt and banking crises, has resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign, and in the net asset values of many mutual funds, including to some extent the Fund. It is uncertain how long these conditions will continue. In addition, global economies and financial markets are becoming increasingly interconnected, which increases the possibilities that conditions in one country or region might adversely impact issuers in a different country or region. The severity or duration of these conditions may also be affected by policy changes made by governments or quasi-governmental organizations.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund pursues its goal by concentrating investments in readily marketable equity securities of companies the principal activities of which include development, ownership, construction, management or sale of residential, commercial or industrial real estate. Investments will include, principally, equity securities of companies in the following sectors of the real estate industry: certain real estate investment trusts (“REITs”), companies engaged in residential construction and firms, excluding partnerships, the principal business of which is to develop commercial property. The Fund generally considers a company to be principally engaged in the real estate industry if the company (i) derives at least 50% of its revenue or profits from the development, ownership, construction, management or sale of residential, commercial, industrial or other real estate; (ii) has at least 50% of the value of its assets invested in residential, commercial, industrial or other real estate; or (iii) is organized as a REIT or REIT-like entity. REIT or REIT-like entities are types of real estate companies that pool investors’ funds for investment primarily in income producing real estate or real estate related loans or interests. The Fund will make equity investments only in securities traded in the U.S. securities markets, primarily on the NYSE, NYSE Alternext US LLC or such other U.S. national securities exchanges and over-the-counter markets, as may be deemed appropriate by the Sub-Adviser using a market capitalization weighted approach.

The Fund purchases shares of REITs. A REIT is not taxed on net income and gains it distributes to shareholders if it complies with several requirements relating to its organization, ownership, assets and income and a requirement that it distribute to its shareholders at least 90% of its taxable income (other than net capital gain) for each taxable year. REITs can generally be classified as equity REITs, mortgage REITs or hybrid REITs. Equity REITs invest the majority of their assets directly in real property and derive their income primarily from rents. Equity REITs can also realize capital gains by selling properties that have appreciated in value. Mortgage REITs invest the majority of their assets in real estate mortgages and derive their income primarily from interest payments. Hybrid REITs combine the characteristics of both equity REITs and mortgage REITs. At the present time, the Fund intends to invest only in equity REITs and hybrid REITs. As a non-fundamental policy, under normal circumstances, at least 80% of the Fund’s net assets will be invested in securities of companies in the real estate industry.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The share price of the Fund may change daily based on market conditions and other factors. Therefore, you may lose money if you invest in the Fund.

The principal risks that apply to the Fund are:

• Market Risk: The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, general economic or market conditions, and/or investor behavior that leads investors’ perceptions of value (as reflected in the stock price) to diverge from fundamental value. Price changes may be temporary or last for extended periods.
   
• Risk of Concentrating in the Real Estate Industry: The Fund’s exclusive focus on the real estate industry will subject the Fund to the general risks of direct real estate ownership. The Fund’s performance may bematerially different from the broad U.S. equity market.
   
• Real Estate Investment Risk: The value of securities in the real estate industry can be affected by changes in real estate values and rental income, property taxes, interest rates, and tax and regulatory requirements. Investing in REITs and REIT-like entities involves certain unique risks in addition to those risks associated with investing in the real estate industry in general. REITs and REIT-like entities are dependent upon management skill, may not be diversified, and are subject to heavy cash flow dependency, defaults by borrowers and self-liquidation. REITs also are subject to the possibility of failing to qualify for tax free pass-through of income. Also, because REITs and REIT-like entities typically are invested in a limited number of projects or in a particular market segment, these entities are more susceptible to adverse developments affecting a single project or market segment than more broadly diversified investments.
   
• Interest Rate Risk: Changes in prevailing interest rates affect not only the value of REIT shares but may also impact the market value of the REIT’s investment real estate.
   
• Cyclical Market Risk: The real estate industry tends to be cyclical with periods of relative under-performance and out-performance in comparison to the broad U.S. equity market. Such cycles may adversely affect the value of the Fund’s portfolio.
   
• Recent Market Conditions: The financial crisis in the U.S. and global economies over the past several years, including the European sovereign debt and banking crises, has resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign, and in the net asset values of many mutual funds, including to some extent the Fund.

In addition, global economies and financial markets are becoming increasingly interconnected, which increases the possibilities that conditions in one country or region might adversely impact issuers in a different country or region.

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 rate 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 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 95% of the average value of its portfolio.

Principal Investment Strategies

The Fund pursues its goal by investing primarily in:

• obligations issued or guaranteed by the U.S. government or its agencies or instrumentalities;
   
• dollar-denominated obligations of foreign issuers issued in the United States;
   
• bank obligations, including those of U.S. banks and savings and loan associations and dollar-denominated obligations of U.S. subsidiaries and branches of foreign banks, such as certificates of deposit (including marketable variable rate certificates of deposit) and bankers’ acceptances;
   
• corporate debt obligations;
   
• commercial paper;
   
• obligations of supranational organizations, such as the World Bank and the European Investment Bank; and
   
• repurchase agreements.

Generally, the Fund acquires obligations that mature within two years from the date of settlement. The Fund has a non-fundamental investment policy that, under normal circumstances, it will invest at least 80% of its net assets in fixed income securities issued in the U.S.

With respect to corporate debt securities (e.g., bonds and debentures), the Fund generally invests in nonconvertible securities that are issued by U.S. issuers and dollar-denominated obligations of foreign issuers issued in the U.S. Such securities must be issued by entities whose commercial paper is rated Prime 1 by Moody’s Investors Service, Inc. (“Moody’s”), at least A1 or better by Standard & Poor’s, a division of The McGraw-Hill Companies, Inc. (“S&P”), or F1 or better by Fitch Ratings Ltd (“Fitch”). If the issuer’s commercial paper is unrated, then the debt security to be purchased must be rated at least AA by S&P, Aa2 by Moody’s or AA by Fitch. If there is neither a commercial paper rating nor a rating of the debt security to be purchased, then the Sub-Adviser must determine that the debt security to be purchased is of comparable quality to equivalent issues of the same issuer rated at least AA by S&P, Aa2 by Moody’s or AA by Fitch.

The Fund may invest in U.S. Treasury bonds, bills and notes and obligations of federal agencies or instrumentalities. Some U.S. government obligations that the Fund may invest in, such as Treasury bills, notes and bonds and securities guaranteed by the Government National Mortgage Association, are supported by the full faith and credit of the United States, while others are not such as those of or guaranteed by the Federal Home Loan Banks, Federal Home Loan Mortgage Corporation and Federal National Mortgage Association.

The Fund will invest more than 25% of its total assets in dollar-denominated obligations of U.S. banks and U.S. subsidiaries and branches of foreign banks and bank holding companies when the yield to maturity on these investments exceeds the yield to maturity on all other eligible portfolio investments of similar quality for a period of five consecutive days during which the New York Stock Exchange (“NYSE”) is open for trading. To determine that yields on dollar-denominated bank obligations are more attractive than yields on all other eligible portfolio investments of similar quality, the Sub-Adviser will examine the yield to maturity information for available fixed income securities of other industry sectors as compared to bank obligations after eliminating individual securities in each industry sector that would not be eligible for investment by the Fund. If the yield to maturity for eligible bank obligations is higher than that of eligible portfolio investments of similar quality of all other industry sectors, investments in bank obligations will be considered to have a yield that generally exceeds the yield on other eligible investments as a group. When investments in such bank obligations exceed 25% of the Fund’s total assets, the Fund will be considered to be concentrating its investments in the banking industry.

The types of bank and bank holding company obligations in which the Fund may invest include: dollar-denominated certificates of deposit, bankers’ acceptances, commercial paper, repurchase agreements and other debt obligations that mature within two years of the date of settlement, provided that such obligations meet the Fund’s established credit rating or other criteria. Commercial paper must be rated A1 or better by S&P, Prime 1 by Moody’s, F1 or better by Fitch or, if not rated, issued by a corporation having an outstanding unsecured debt issue rated Aaa by Moody’s, AAA by S&P or AAA by Fitch. Bank certificates of deposit will only be acquired from banks having assets in excess of $1 billion. The Fund will not enter into repurchase agreements with a bank unless the bank has at least $1 billion in assets and is approved by the Investment Committee of the Sub-Adviser.

All ratings described above apply at the time of investment.

Principal Investment Risks

The Fund’s share price and yield may change daily because of changes in interest rates and other market conditions and factors. Therefore, you may lose money if you invest in the Fund.

The principal risks that apply to the Fund are:

• Market Risk: The value of the securities in which the Fund invests may go up or down in response to the prospects of individual issuers, general economic or market conditions, and/or investor behavior that leads investors’ perceptions of value (as reflected in the price of the security) to diverge from fundamental value.
   
• Interest Rate and Related Risks: Generally, when market interest rates rise, the value of debt securities declines, and vice versa. Investing in such securities means that the Fund’s net asset value will tend to decline if market interest rates rise. Interest rate risk is generally greater for fixed-income securities with longer maturities or durations. During periods of rising interest rates, the average life of certain types of securities in which the Fund invests may be extended because of slower than expected principal payments. This may lock in a below-market interest rate, increase the security’s duration (i.e., the estimated period until the principal and interest are paid in full) and reduce the value of the security. This is known as extension risk. During periods of declining interest rates, issuers of certain securities may exercise their option to prepay principal earlier than scheduled, forcing the Fund to reinvest in lower yielding securities. This is known as call or prepayment risk.
   
• Credit Risk: It is possible that some issuers or guarantors may default on debt securities held by the Fund, or there could be defaults on repurchase agreements held by the Fund. Also, an issuer may suffer adverse changes in financial condition that could result in a downgrade in credit rating leading to greater volatility in the price of the security and, consequently, in the price of shares of the Fund. A change in the credit rating of a bond can also affect the bond’s liquidity and make it more difficult for the Fund to sell. Credit ratings are only the opinions of the rating agencies issuing them, do not purport to reflect the risk of fluctuations in market value and are not guarantees as to the payment of interest and repayment of principal.
   
• Income Risk: Because the Fund can only distribute what it earns, the Fund’s distributions to shareholders may decline when prevailing interest rates fall or if the Fund experiences defaults on debt securities it holds.
   
• U.S. Government Securities Risk: Although the Fund may invest in securities that carry U.S. government guarantees, these guarantees do not extend to shares of the Fund itself and do not guarantee the market price of the securities. Furthermore, not all securities issued by the U.S. government and its agencies and instrumentalities are backed by the full faith and credit of the U.S. Treasury. There is no guarantee that the U.S. government will support securities not backed by its full faith and credit.
   
• Banking Concentration Risk: To the extent the Fund invests more than 25% of its total assets in bank and bank holding company obligations, such banking industry investments would link the performance of the Fund to changes in the performance of the banking industry generally. Banks are subject to extensive government regulation that may affect the scope of their activities, their profitability, the prices that they can charge and the amount of capital that they must maintain. In addition, unstable interest rates can have a disproportionate effect on the banking industry; banks whose securities the Fund may purchase may themselves have concentrated portfolios of loans or investments that make them vulnerable to economic conditions that affect that industry.
   
• Recent Market Conditions: The financial crisis in the U.S. and global economies over the past several years, including the European sovereign debt and banking crises, has resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign, and in the net asset values of many mutual funds, including to some extent the Fund. It is uncertain how long these conditions will continue. These market conditions have resulted, and may continue to result, in fixed income instruments experiencing unusual liquidity issues, increased price volatility and, in some cases, credit downgrades and increased likelihood of default. In addition, global economies and financial markets are becoming increasingly interconnected, which increases the possibilities that conditions in one country or region might adversely impact issuers in a different country or region. The severity or duration of these conditions may also be affected by policy changes made by governments or quasi-governmental organizations.

Expense Example (USD $)	1 year	3 years	5 years	10 years
SA Global Fixed Income Fund	82	256	444	990

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 rate 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 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 36% of the average value of its portfolio.

Principal Investment Strategies

The Fund pursues its goal by investing primarily in:

• obligations issued or guaranteed by the U.S. and foreign governments of developed countries or their agencies or instrumentalities;
   
• obligations of supranational organizations, such as the World Bank and the European Investment Bank;
   
• obligations of other U.S. and foreign issuers including:

• corporate debt obligations;
   
• commercial paper;
   
• bank obligations; and
   
• repurchase agreements.

The Fund primarily invests in fixed income securities that mature within five years from the date of settlement. The Fund has a non-fundamental investment policy that, under normal circumstances, it will invest at least 80% of its net assets in fixed income securities.

The Fund may invest in U.S. Treasury bonds, bills and notes and obligations of federal agencies or instrumentalities. Some U.S. government obligations in which the Fund may invest, such as Treasury bills, notes and bonds and securities guaranteed by the Government National Mortgage Association, are supported by the full faith and credit of the United States, while others are not such as those of or guaranteed by the Federal Home Loan Banks, Federal Home Loan Mortgage Corporation and Federal National Mortgage Association.

The Fund may also invest in fixed income securities issued or guaranteed by foreign governments or their agencies or instrumentalities such as bills, notes, bonds and other debt securities and may invest in debt securities of supranational organizations. With respect to such securities, the Fund will generally invest in fixed income securities of issuers whose short-term debt rating is rated Prime 1 by Moody’s, at least A1 or better by S&P or F1 or better by Fitch. If the issuer does not have a short-term debt rating, then the debt security to be purchased must be rated at least AA by S&P, Aa2 by Moody’s or AA by Fitch. If there is neither a short-term debt rating nor a rating of the debt security to be purchased, then the Sub-Adviser must determine that the debt security to be purchased is of comparable quality to equivalent issues of the same issuer rated at least AA by S&P, Aa2 by Moody’s or AA by Fitch.

With respect to corporate debt securities (e.g., bonds and debentures), the Fund generally invests in nonconvertible securities that are issued by U.S. and foreign issuers whose commercial paper is rated Prime 1 by Moody’s, at least A1 or better by S&P or F1 or better by Fitch. If the issuer’s commercial paper is unrated, then the debt security to be purchased must be rated at least AA by S&P, Aa2 by Moody’s or AA by Fitch. If there is neither a commercial paper rating nor a rating of the debt security to be purchased, then the Sub-Adviser must determine that the debt security to be purchased is of comparable quality to equivalent issues of the same issuer rated at least AA by S&P, Aa2 by Moody’s or AA by Fitch.

The types of bank and bank holding company obligations in which the Fund may invest include, without limitation: certificates of deposit (including marketable variable rate certificates of deposit), bankers’ acceptances, commercial paper, repurchase agreements and other debt obligations that mature within five years of the date of settlement, provided such obligations meet the Fund’s established credit rating or other criteria. Commercial paper must be rated A1 or better by S&P, Prime 1 by Moody’s, F1 or better by Fitch or, if not rated, issued by a corporation having an outstanding unsecured debt issue rated Aaa by Moody’s, AAA by S&P or AAA by Fitch. Bank certificates of deposit will only be acquired from banks having assets in excess of $1 billion. The Fund will not enter into repurchase agreements with a bank unless the bank has at least $1 billion in assets and is approved by the Investment Committee of the Sub-Adviser.

All ratings described above apply at the time of investment.

These securities may be denominated in U.S. dollars as well as other currencies, including the Euro. The Fund invests in foreign issuers in countries with developed markets designated by the Investment Committee of the Sub-Adviser from time to time. As of the date of this Prospectus, the Fund is authorized to invest in foreign issuers in Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Japan, Luxembourg, the Netherlands, New Zealand, Norway, Singapore, Sweden, Switzerland and the United Kingdom. This list of authorized countries is subject to change. The Sub-Adviser will determine when and whether to invest in countries that have been authorized, depending on a number of factors, such as asset availability in the Fund and characteristics of each country’s market. Under normal market conditions, the Fund will invest (1) at least 40% (and up to 100%) of its total assets in the securities of foreign issuers and (2) in issuers organized or having a majority of their assets in, or deriving a majority of their operating income from, at least three different countries, one of which may be the United States. The actual number of countries represented in the Fund’s portfolio may vary over time.

The Fund attempts to maximize its total return by allocating assets among countries depending on prevailing interest rates while targeting the duration of the Fund’s benchmark index. For example, the Sub-Adviser may sell a security denominated in one currency and buy a security denominated in a different currency depending on market conditions. The Fund will invest no more than 50% of its total assets in securities denominated in U.S. dollars at the time of purchase.

The Fund may enter into forward foreign currency exchange contracts to hedge foreign currency risks. The Fund may also lend its portfolio securities to generate additional income.

Principal Investment Risks

The Fund’s share price and yield may change daily because of changes in interest rates and other market conditions and factors. Therefore, you may lose money if you invest in the Fund.

The principal risks that apply to the Fund are:

• Market Risk: The value of the securities in which the Fund invests may go up or down in response to the prospects of individual issuers, general economic or market conditions, and/or investor behavior that leads investors’ perceptions of value (as reflected in the price of the security) to diverge from fundamental value.
   
• Interest Rate and Related Risks: Generally, when market interest rates rise, the value of debt securities declines, and vice versa. Investing in such securities means that the Fund’s net asset value will tend to decline if market interest rates rise. Interest rate risk is generally greater for fixed-income securities with longer maturities or durations. During periods of rising interest rates, the average life of certain types of securities in which the Fund invests may be extended because of slower than expected principal payments. This may lock in a below-market interest rate, increase the security’s duration (i.e., the estimated period until the principal and interest are paid in full) and reduce the value of the security. This is known as extension risk. During periods of declining interest rates, issuers of certain securities may exercise their option to prepay principal earlier than scheduled, forcing the Fund to reinvest in lower yielding securities. This is known as call or prepayment risk.
   
• Credit Risk: It is possible that some issuers or guarantors may default on debt securities held by the Fund, or there could be defaults on repurchase agreements held by the Fund. Also, an issuer may suffer adverse changes in financial condition that could result in a downgrade in credit rating leading to greater volatility in the price of the security and, consequently, in the price of shares of the Fund. A change in the credit rating of a bond can also affect the bond’s liquidity and make it more difficult for the Fund to sell. Credit ratings are only the opinions of the rating agencies issuing them, do not purport to reflect the risk of fluctuations in market value and are not guarantees as to the payment of interest and repayment of principal.
   
• Income Risk: Because the Fund can only distribute what it earns, the Fund’s distributions to shareholders may decline when prevailing interest rates fall or if the Fund experiences defaults on debt securities it holds.
   
• Foreign Securities and Currency Risk: Foreign securities involve risks in addition to those associated with comparable U.S. securities. Investments in foreign securities are subject to fluctuations in currency exchange rates, which may negatively affect the value of the Fund’s portfolio. Additional risks may include exposure to less developed or less efficient trading markets; social, political or economic instability; currency controls or redenomination; changes in tax policy; high transaction costs; settlement, custodial or other operational risks; and less stringent accounting, auditing, financial reporting, and legal standards and practices. As a result, foreign securities can fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities.
   
• Foreign Government and Supranational Organization Obligations Risk: By investing in foreign government obligations, the Fund will be exposed to the direct or indirect consequences of political, social, and economic changes in various countries. The Fund may have limited legal recourse in the event of a default with respect to foreign government and supranational organization obligations it holds.
   
• Hedging Risk: Forward foreign currency exchange contracts may be used to hedge foreign currency risk. Hedging tends to limit any potential gain that may be realized if the value of the Fund’s portfolio holdings increases because of currency fluctuations. In addition, hedging may increase the Fund’s expenses. There is also a risk that a forward foreign currency exchange contract intended as a hedge may not perform as intended, in which case the Fund may not be able to minimize the effects of foreign currency fluctuations and may suffer a loss.
   
• Securities Lending Risk: Securities lending involves possible delay in recovery of the securities or possible loss of rights in the collateral should the borrower fail financially. As a result, the value of the Fund shares may fall. The value of the Fund shares could also fall if a loan is called and the Fund is required to liquidate reinvested collateral at a loss or if the Fund is unable to reinvest cash collateral at rates which exceed the costs involved.
   
• European Economic Risk: Recently, the European financial markets have been negatively impacted by rising government debt levels; possible default on or restructuring of sovereign debt in several European countries, including Greece, Ireland, Italy, Portugal and Spain; and economic downturns. A European country’s default or debt restructuring would adversely affect the holders of the country’s debt and sellers of credit default swaps linked to the country’s creditworthiness and could negatively impact global markets more generally. Recent events in Europe have adversely affected the euro’s exchange rate and value and may continue to impact the economies of every European country.
   
• U.S. Government Securities Risk: Although the Fund may invest in securities that carry U.S. government guarantees, these guarantees do not extend to shares of the Fund itself and do not guarantee the market price of the securities. Furthermore, not all securities issued by the U.S. government and its agencies and instrumentalities are backed by the full faith and credit of the U.S. Treasury. There is no guarantee that the U.S. government will support securities not backed by its full faith and credit.
   
• Recent Market Conditions: The financial crisis in the U.S. and global economies over the past several years, including the European sovereign debt and banking crises, has resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign, and in the net asset values of many mutual funds, including to some extent the Fund. It is uncertain how long these conditions will continue. These market conditions have resulted, and may continue to result, in fixed income instruments experiencing unusual liquidity issues, increased price volatility and, in some cases, credit downgrades and increased likelihood of default. In addition, global economies and financial markets are becoming increasingly interconnected, which increases the possibilities that conditions in one country or region might adversely impact issuers in a different country or region.

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 rate 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 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 6% of the average value of its portfolio.

Principal Investment Strategies

The Fund pursues its goal by generally selecting from all common stocks that are traded on a principal U.S. exchange or on the over-the-counter market in the United States. As of the date of this Prospectus, the Sub-Adviser has narrowed the target universe of stocks to securities of companies whose market capitalizations generally are either in the highest 96% of total market capitalizationor companies whose market capitalizations are larger than the 1,500^th largest U.S. company, whichever results in the higher market capitalization threshold. Under the Sub-Adviser’s market capitalization guidelines described above, as of August 31, 2012, the target universe was defined by the market capitalization of the 96% of total market capitalization, which was approximately $1,069 million or above. This dollar amount will change due to market conditions. The Fund has a non-fundamental investment policy that, under normal circumstances, it will invest at least 80% of its net assets in U.S. securities.

The Fund also invests less than 5% of its total assets in the U.S. Micro Cap Portfolio, a portfolio of DFA Investment Dimensions Group Inc., a separate registered investment company. The Sub-Adviser is also the adviser of the U.S. Micro Cap Portfolio. The U.S. Micro Cap Portfolio generally will purchase a broad and diverse group of the common stocks of micro cap companies traded on a principal U.S. exchange or the over-the-counter market.

The Fund may lend its portfolio securities to generate additional income.

Principal Investment Risks

The share price of the Fund may change daily based on market conditions and other factors. Therefore, you may lose money if you invest in the Fund.

The principal risks that apply to the Fund are:

• Market Risk: The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, general economic or market conditions, and/or investor behavior that leads investors’ perceptions of value (as reflected in the stock price) to diverge from fundamental value.
   
• Large Company Stock Risk: Larger, more established companies may be unable to respond quickly to competitive challenges, such as changes in technology and consumer tastes.
   
• Medium-Size Company Stock Risk: Stocks of medium-size companies are usually more sensitive to adverse business developments and economic, political, regulatory and market factors than stocks of larger companies, and the prices of stocks of medium-size companies may be more volatile.
   
• Small Company Stock Risk: The stocks of small companies may have more risks than those of larger companies. Small companies often have narrower markets and more limited managerial and financial resources than larger, more established companies. As a result, they may be more sensitive to changing economic conditions, which could increase the volatility of the Fund’s portfolio. In addition, small company stocks typically are traded in lower volume, making them more difficult to purchase or sell. Generally, the smaller the company size, the greater these risks.
   
• Securities Lending Risk: Securities lending involves possible delay in recovery of the securities or possible loss of rights in the collateral should the borrower fail financially. As a result, the value of the Fund shares may fall. The value of the Fund shares could also fall if a loan is called and the Fund is required to liquidate reinvested collateral at a loss or if the Fund is unable to reinvest cash collateral at rates which exceed the costs involved.
   
• Recent Market Conditions: The financial crisis in the U.S. and global economies over the past several years, including the European sovereign debt and banking crises, has resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign, and in the net asset values of many mutual funds, including to some extent the Fund. It is uncertain how long these conditions will continue. In addition, global economies and financial markets are becoming increasingly interconnected, which increases the possibilities that conditions in one country or region might adversely impact issuers in a different country or region. The severity or duration of these conditions may also be affected by policy changes made by governments or quasi-governmental organizations.

Expense example

This expense 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 periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same and the expense limitation remains in place for the time period indicated. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	1 year	3 years	5 years	10 years
SA U.S. Value Fund	107	334	579	1,282

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 rate 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 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 11% of the average value of its portfolio.

Principal Investment Strategies

The Fund pursues its goal by generally investing in a target universe consisting of common stocks of large and mid cap U.S. companies traded on a principal U.S. exchange or on the over-the-counter market in the United States that the Sub-Adviser believes are “value” stocks at the time of purchase. The Sub-Adviser considers value stocks primarily to be those of companies with high book values (values that are derived from a company’s balance sheet) in relation to their market values (values that are derived by multiplying the market price per share of a company’s stock by the number of outstanding shares of that stock). In measuring value, the Sub-Adviser may also consider such factors as price-to-cash flow or price-to-earnings ratios, economic conditions and developments in the company’s industry. The criteria used for assessing value are subject to change from time to time. As of the date of this Prospectus, the Sub-Adviser considers large and mid cap companies to be companies whose market capitalizations generally are either in the highest 90% of total market capitalization or companies whose market capitalizations are larger than the 1,000^th largest U.S. company, whichever results in the higher market capitalization threshold. Under the Sub-Adviser’s market capitalization guidelines described above, as of August 31, 2012, the market capitalization of a large or mid cap company was defined by the market capitalization of a company in the highest 90% of total market capitalization, which was approximately $2,673 million or above. This dollar amount will change due to market conditions. The Fund has a non-fundamental investment policy that, under normal circumstances, it will invest at least 80% of its net assets in U.S. securities.

The Fund may lend its portfolio securities to generate additional income.

Principal Investment Risks

The share price of the Fund may change daily based on market conditions and other factors. Therefore, you may lose money if you invest in the Fund.

The principal risks that apply to the Fund are:

• Market Risk: The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, general economic or market conditions, and/or investor behavior that leads investors’ perceptions of value (as reflected in the stock price) to diverge from fundamental value.
   
• Value Stock Risk: A value stock may not reach what the Sub-Adviser believes is its full market value, or its intrinsic value may go down. In addition, value stocks may underperform when the market favors growth stocks over value stocks.
   
• Large Company Stock Risk: Larger, more established companies may be unable to respond quickly to competitive challenges, such as changes in technology and consumer tastes.
   
• Medium-Size Company Stock Risk: Stocks of medium-size companies are usually more sensitive to adverse business developments and economic, political, regulatory and market factors than stocks of larger companies, and the prices of stocks of medium-size companies may be more volatile. The Fund may experience difficulty in purchasing or selling securities of medium-size companies at the desired time and price.
   
• Securities Lending Risk: Securities lending involves possible delay in recovery of the securities or possible loss of rights in the collateral should the borrower fail financially. As a result, the value of the Fund shares may fall. The value of the Fund shares could also fall if a loan is called and the Fund is required to liquidate reinvested collateral at a loss or if the Fund is unable to reinvest cash collateral at rates which exceed the costs involved.

Principal Investment Strategies

The Fund pursues its goal by generally investing in a target universe consisting of common stocks of small cap companies traded on a principal U.S. exchange or on the over-the-counter market in the United States.

A higher portfolio turnover rate 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 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 22% of the average value of its portfolio.

Principal Investment Strategies

The Fund pursues its goal by generally investing in a target universe consisting of securities of large cap non-U.S. companies that the Sub-Adviser believes are “value” stocks at the time of purchase. The Sub-Adviser considers value stocks primarily to be those of companies with high book values (values that are derived from a company’s balance sheet) in relation to their market values (values that are derived by multiplying the market price per share of a company’s stock by the number of outstanding shares of that stock). In measuring value, the Sub-Adviser may also consider such factors as price-to-cash flow or price-to-earnings ratios, economic conditions and developments in the company’s industry. The criteria used for assessing value are subject to change from time to time.

The Fund invests in companies in countries with developed markets designated by the Investment Committee of the Sub-Adviser as approved markets from time to time. As of the date of this Prospectus, the Fund is authorized to invest in the stocks of large cap companies in Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Greece, Hong Kong, Ireland, Israel, Italy, Japan, the Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland and the United Kingdom. This list of authorized countries is subject to change. Under normal market conditions, the Sub-Adviser intends to invest in companies organized or having a majority of their operating income from sources in at least three non-U.S. countries.

The Sub-Adviser determines company size on a country- or region-specific basis and based primarily on market capitalization. In the countries or regions authorized for investment, the Sub-Adviser first ranks eligible companies listed on selected exchanges based on the companies’ market capitalizations. The Sub-Adviser then determines the universe of eligible stocks by defining the minimum market capitalization of a large cap company that may be purchased by the Fund with respect to each country or region. As of August 31, 2012, the lowest minimum market capitalization of a large cap company in any country or region in which the Fund invests was $1,443 million. This threshold will vary by country and region and will change with market conditions.

The Fund intends to purchase securities within each authorized country using a market capitalization weighted approach. The Sub-Adviser, using this approach and its judgment, will seek to set country weights based on the relative market capitalization of eligible large cap non-U.S. companies within each country.

The Fund may lend its portfolio securities to generate additional income.

Principal Investment Risks

The share price of the Fund may change daily based on market conditions and other factors. Therefore, you may lose money if you invest in the Fund.

The principal risks that apply to the Fund are:

• Market Risk: The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, general economic or market conditions, and/or investor behavior that leads investors’ perceptions of value (as reflected in the stock price) to diverge from fundamental value.
   
• Foreign Securities and Currency Risk: Foreign securities involve risks in addition to those associated with comparable U.S. securities. Investments in foreign securities are subject to fluctuations in currency exchange rates, which may negatively affect the value of the Fund’s portfolio. Additional risks may include exposure to less developed or less efficient trading markets; social, political or economic instability; currency controls or redenomination; changes in tax policy; high transaction costs; settlement, custodial or other operational risks; and less stringent accounting, auditing, financial reporting, and legal standards and practices. As a result, foreign securities can fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities.
   
• European Economic Risk: Recently, the European financial markets have been negatively impacted by rising government debt levels; possible default on or restructuring of sovereign debt in several European countries, including Greece, Ireland, Italy, Portugal and Spain; and economic downturns. A European country’s default or debt restructuring would adversely affect the holders of the country’s debt and sellers of credit default swaps linked to the country’s creditworthiness and could negatively impact global markets more generally. Recent events in Europe have adversely affected the euro’s exchange rate and value and may continue to impact the economies of every European country.
   
• Large Company Stock Risk: Larger, more established companies may be unable to respond quickly to competitive challenges, such as changes in technology and consumer tastes.
   
• Value Stock Risk: A value stock may not reach what the Sub-Adviser believes is its full market value, or its intrinsic value may go down. In addition, value stocks may underperform when the market favors growth stocks over value stocks.
   
• Securities Lending Risk: Securities lending involves possible delay in recovery of the securities or possible loss of rights in the collateral should the borrower fail financially. As a result, the value of the Fund shares may fall. The value of the Fund shares could also fall if a loan is called and the Fund is required to liquidate reinvested collateral at a loss or if the Fund is unable to reinvest cash collateral at rates which exceed the costs involved.
   
• Recent Market Conditions: The financial crisis in the U.S. and global economies over the past several years, including the European sovereign debt and banking crises, has resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign, and in the net asset values of many mutual funds, including to some extent the Fund. It is uncertain how long these conditions will continue. In addition, global economies and financial markets are becoming increasingly interconnected, which increases the possibilities that conditions in one country or region might adversely impact issuers in a different country or region. The severity or duration of these conditions may also be affected by policy changes made by governments or quasi-governmental organizations.

Portfolio Turnover

A mutual fund generally pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when mutual fund shares are held in a taxable account. The Fund does not pay transaction costs when buying and selling shares of the DFA Portfolio and the DFA Portfolio does not pay transaction costs when buying and selling shares of the Underlying Funds (as defined below); however, each of the Underlying Funds pay transaction costs when buying and selling securities for its portfolio. The transaction costs incurred by the Underlying Funds, which are not reflected in Annual Fund Operating Expenses or in the expense example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 0% of the average value of its portfolio.

Principal Investment Strategies

Instead of buying securities directly, the Fund invests substantially all of its assets in the DFA Portfolio, which has the same investment objective and investment policies as the Fund. The DFA Portfolio seeks to provide investors with access to securities portfolios consisting of a broad range of equity securities of primarily small Japanese, United Kingdom, European (including the Mediterranean), Asia Pacific and Canadian companies. The DFA Portfolio invests substantially all of its assets in: The Japanese Small Company Series (the “Japanese Series”), The United Kingdom Small Company Series (the “United Kingdom Series”), The Continental Small Company Series (the “Continental Series”), The Asia Pacific Small Company Series (the “Asia Pacific Series”) and The Canadian Small Company Series (the “Canadian Series”) (each an “Underlying Fund” and together, the “Underlying Funds”), each of which is a series of The DFA Investment Trust Company. Each Underlying Fund invests in small companies using a market capitalization weighted approach in each country or region designated by the Sub-Adviser as an approved market for investment. The DFA Portfolio also may have some exposure to small cap equity securities associated with other countries or regions. As a non-fundamental policy, under normal circumstances, the Fund, through its investments in the DFA Portfolio and, indirectly, the Underlying Funds, will invest at least 80% of its net assets in securities of small companies.

As of August 31, 2012, the DFA Portfolio invested its assets in the Underlying Funds within the following ranges (expressed as a percentage of the DFA Portfolio’s assets):

Underlying Fund	Investment Range
Japanese Series		10% - 35%
United Kingdom Series		10% - 30%
Continental Series		25% - 50%
Asia Pacific Series		0% - 25%
Canadian Series		0% - 20%

The allocation of the assets of the DFA Portfolio to be invested in the Underlying Funds will be determined by the Sub-Adviser on at least a semi-annual basis. The Underlying Funds invest in countries that the Sub-Adviser views as developed market countries and will not invest in emerging market countries. Each Underlying Fund may lend its portfolio securities to generate additional income.

The DFA Portfolio and the Underlying Funds are advised by the Sub-Adviser. For as long as the Fund invests substantially all of its assets in the DFA Portfolio, the Sub-Adviser will not receive any sub-advisory fee from the Fund for its sub-advisory services. The Sub-Adviser receives an administration fee and an investment advisory fee from its management of the DFA Portfolio and the Underlying Funds. The Sub-Adviser has agreed to this fee arrangement in order to prevent duplication of advisory fees to the Sub-Adviser.

The Fund may withdraw its investment in the DFA Portfolio at any time if the Fund’s Board of Trustees determines that it is in the best interest of the Fund and its shareholders to do so. If this happens, the Fund’s assets either will be invested in another mutual fund or will be invested directly according to the investment policies and restrictions described in this Prospectus.

Principal Investment Risks

The share price of the Fund may change daily based on market conditions and other factors. Therefore, you may lose money if you invest in the Fund.

The principal risks that apply to the Fund are:

• Fund of Funds Risk: The investment performance of the Fund is affected by the investment performance of the DFA Portfolio and, indirectly, the investment performance of the Underlying Funds. The ability of the Fund to achieve its investment objective depends on the ability of the DFA Portfolio and the Underlying Funds to meet their investment objectives and on the Sub-Adviser’s decisions regarding the allocation of the DFA Portfolio’s assets among the Underlying Funds. There can be no assurance that the investment objective of the Fund, the DFA Portfolio or any Underlying Fund will be achieved. Through its investment in the DFA Portfolio and, indirectly, the Underlying Funds, the Fund is subject to the risks of the Underlying Funds’ investments. The risks of the Underlying Funds’ investments are described below. Duplication of expenses is a risk when a fund invests in other investment companies.
   
• Market Risk: The value of the securities in which the Underlying Funds invest may go up or down in response to the prospects of individual companies, general economic or market conditions, and/or investor behavior that leads investors’ perceptions of value (as reflected in the stock price) to diverge from fundamental value. 
   
• Small Company Stock Risk: The stocks of small companies may have more risks than those of larger companies. Small companies often have narrower markets and more limited managerial and financial resources than larger, more established companies. As a result they may be more sensitive to changing economic conditions, which could increase the volatility of the Underlying Funds’ portfolios. In addition, small company stocks typically are traded in lower volume, making them more difficult to purchase or sell. Generally, the smaller the company size, the greater these risks.
   
• Foreign Securities and Currency Risk: Foreign securities involve risks in addition to those associated with comparable U.S. securities. Investments in foreign securities are subject to fluctuations in currency exchange rates, which may negatively affect the value of the Fund’s portfolio. Additional risks may include exposure to less developed or less efficient trading markets; social, political or economic instability; currency controls or redenomination; changes in tax policy; high transaction costs; settlement, custodial or other operational risks; and less stringent accounting, auditing, financial reporting, and legal standards and practices. As a result, foreign securities can fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities.
   
• Securities Lending Risk: Securities lending involves possible delay in recovery of the securities or possible loss of rights in the collateral should the borrower fail financially. As a result, the value of the Underlying Fund shares (and, indirectly, the Fund shares) may fall. The value of the Underlying Fund shares (and, indirectly, the Fund shares) could also fall if a loan is called and the Underlying Fund is required to liquidate reinvested collateral at a loss or if the Underlying Fund is unable to reinvest cash collateral at rates which exceed the costs involved.
   
• European Economic Risk: Recently, the European financial markets have been negatively impacted by rising government debt levels; possible default on or restructuring of sovereign debt in several European countries, including Greece, Ireland, Italy, Portugal and Spain; and economic downturns. A European country’s default or debt restructuring would adversely affect the holders of the country’s debt and sellers of credit default swaps linked to the country’s creditworthiness and could negatively impact global markets more generally. Recent events in Europe have adversely affected the euro’s exchange rate and value and may continue to impact the economies of every European country. 
   
• Recent Market Conditions: The financial crisis in the U.S. and global economies over the past several years, including the European sovereign debt and banking crises, has resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign, and in the net asset values of many mutual funds, including to some extent the Fund. It is uncertain how long these conditions will continue. In addition, global economies and financial markets are becoming increasingly interconnected, which increases the possibilities that conditions in one country or region might adversely impact issuers in a different country or region. The severity or duration of these conditions may also be affected by policy changes made by governments or quasi-governmental organizations.

In certain situations, the “Return After Taxes on Distributions and Sale of Fund Shares” may be higher than the other return figures for the same period. A higher after-tax return can occur when a capital loss occurs upon redemption and translates into an assumed tax deduction that benefits the shareholder. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns shown are not relevant to investors who hold their Fund shares through tax-advantaged arrangements, such as 401(k) plans or individual retirement accounts.

Expense example

This expense 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 periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same and the expense limitation remains in place for the time period indicated. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	1 year	3 years	5 years	10 years
SA Emerging Markets Value Fund	148	459	793	1,736

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 rate 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 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 13% of the average value of its portfolio.

Principal Investment Strategies

The Fund pursues its goal by purchasing a broad and diverse group of securities of companies in emerging markets, which may include frontier markets (i.e., emerging market countries in an earlier stage of development). The Fund intends to purchase companies with small, medium and large market capitalizations in their respective markets that the Sub-Adviser considers to be “value” stocks.

The Fund seeks to achieve its goal by investing in companies in countries designated by the Investment Committee of the Sub-Adviser from time to time as approved markets. As of the date of this Prospectus, the Fund is authorized to invest in the following approved markets: Brazil, Chile, China, Colombia, the Czech Republic, Hungary, India, Indonesia, Malaysia, Mexico, the Philippines, Poland, Russia, South Africa, South Korea, Taiwan, Thailand, and Turkey. The Sub-Adviser may authorize other countries for investment in the future in addition to the approved markets listed above. In addition, the Fund may also continue to hold securities associated with countries that are not listed above as approved markets but had been authorized for investment in the past and may reinvest distributions received in connection with such existing investments in such previously approved countries. As a non-fundamental policy, under normal circumstances, the Fund will invest at least 80% of its net assets in emerging markets investments that are approved market securities.

The Fund seeks to purchase securities of small, medium and large companies that are representative of broad market coverage within each approved market. The Fund’s definition of what constitutes a small, medium and large company varies across countries and is based primarily on market capitalization. In each approved market, the companies listed on selected exchanges are ranked based upon their market capitalizations. The minimum market capitalization for a company in that country is then defined. As of August 31, 2012, Mexico had the highest market capitalization threshold for investment of approximately $1,634 million; and Hungary had the lowest market capitalization threshold for investment of approximately $236 million. These dollar amounts will change due to market conditions.

In assessing value, the Sub-Adviser primarily considers a security’s book value (value that is derived from a company’s balance sheet) in relation to its market value (value that is derived by multiplying the market price per share of a company’s stock by the number of outstanding shares of that stock). However, the Sub-Adviser may also consider factors such as price-to-cash flow or price-to-earnings ratios, as well as economic conditions and developments in the company’s industry. The criteria the Sub-Adviser uses for assessing value are subject to change from time to time. The Fund may not invest in certain companies or approved markets for reasons that include constraints imposed within approved markets (e.g., restrictions on purchases by foreigners), and the Fund’s policy not to invest more than 25% of its assets in any one industry.

Principal Investment Risks

The share price of the Fund may change daily based on market conditions and other factors. Therefore, you may lose money if you invest in the Fund.

The principal risks that apply to the Fund are:

• Market Risk: The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, general economic or market conditions, and/or investor behavior that leads investors’ perceptions of value (as reflected in the stock price) to diverge from fundamental value.
   
• Emerging Markets Risk: Investing in emerging market countries involves risks in addition to those generally associated with investing in developed foreign countries. Securities issued in these countries may be more volatile and less liquid than securities issued in foreign countries with more developed economies or markets. Numerous emerging market countries have experienced serious, and frequently continuing, economic and political problems. Foreigners are often limited in their ability to invest in, and withdraw assets from, these markets.
   
• Value Stock Risk: A value stock may not reach what the Sub-Adviser believes is its full market value, or its intrinsic value may go down. In addition, value stocks may underperform when the market favors growth stocks over value stocks.
   
• Large Company Stock Risk: Larger, more established companies may be unable to respond quickly to competitive challenges, such as changes in technology and consumer tastes.
   
• Medium-Size Company Stock Risk: Stocks of medium-size companies are usually more sensitive to adverse business developments and economic, political, regulatory and market factors than stocks of large companies, and the prices of stocks of medium-size companies may be more volatile.
   
• Small Company Stock Risk: The stocks of small companies may have more risks than those of larger companies. Small companies often have narrower markets and more limited managerial and financial resources than larger, more established companies. As a result, they may be more sensitive to changing economic conditions, which could increase the volatility of the Fund’s portfolio. In addition, small company stocks typically are traded in lower volume, making them more difficult to purchase or sell. Generally, the smaller the company size, the greater these risks.
   
• Foreign Securities and Currency Risk: Foreign securities involve risks in addition to those associated with comparable U.S. securities. Investments in foreign securities are subject to fluctuations in currency exchange rates, which may negatively affect the value of the Fund’s portfolio. Additional risks may include exposure to less developed or less efficient trading markets; social, political or economic instability; currency controls or redenomination; nationalization or expropriation of assets; changes in tax policy; high transaction costs; settlement, custodial or other operational risks; and less stringent accounting, auditing, financial reporting, and legal standards and practices. In addition, key information about the issuer, the markets or the local government or economy may be unavailable, incomplete or inaccurate. As a result, foreign securities can fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities.

• Recent Market Conditions: The financial crisis in the U.S. and global economies over the past several years, including the European sovereign debt and banking crises, has resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign, and in the net asset values of many mutual funds, including to some extent the Fund. It is uncertain how long these conditions will continue. In addition, global economies and financial markets are becoming increasingly interconnected, which increases the possibilities that conditions in one country or region might adversely impact issuers in a different country or region.

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 rate 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 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 4% of the average value of its portfolio.

Principal Investment Strategies

The Fund pursues its goal by concentrating investments in readily marketable equity securities of companies the principal activities of which include development, ownership, construction, management or sale of residential, commercial or industrial real estate. Investments will include, principally, equity securities of companies in the following sectors of the real estate industry: certain real estate investment trusts (“REITs”), companies engaged in residential construction and firms, excluding partnerships, the principal business of which is to develop commercial property. The Fund generally considers a company to be principally engaged in the real estate industry if the company (i) derives at least 50% of its revenue or profits from the development, ownership, construction, management or sale of residential, commercial, industrial or other real estate; (ii) has at least 50% of the value of its assets invested in residential, commercial, industrial or other real estate; or (iii) is organized as a REIT or REIT-like entity. REIT or REIT-like entities are types of real estate companies that pool investors’ funds for investment primarily in income producing real estate or real estate related loans or interests. The Fund will make equity investments only in securities traded in the U.S. securities markets, primarily on the NYSE, NYSE Alternext US LLC or such other U.S. national securities exchanges and over-the-counter markets, as may be deemed appropriate by the Sub-Adviser using a market capitalization weighted approach.

The Fund purchases shares of REITs. A REIT is not taxed on net income and gains it distributes to shareholders if it complies with several requirements relating to its organization, ownership, assets and income and a requirement that it distribute to its shareholders at least 90% of its taxable income (other than net capital gain) for each taxable year. REITs can generally be classified as equity REITs, mortgage REITs or hybrid REITs. Equity REITs invest the majority of their assets directly in real property and derive their income primarily from rents. Equity REITs can also realize capital gains by selling properties that have appreciated in value. Mortgage REITs invest the majority of their assets in real estate mortgages and derive their income primarily from interest payments. Hybrid REITs combine the characteristics of both equity REITs and mortgage REITs. At the present time, the Fund intends to invest only in equity REITs and hybrid REITs. As a non-fundamental policy, under normal circumstances, at least 80% of the Fund’s net assets will be invested in securities of companies in the real estate industry.

Principal Investment Risks

The share price of the Fund may change daily based on market conditions and other factors. Therefore, you may lose money if you invest in the Fund.

The principal risks that apply to the Fund are:

• Market Risk: The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, general economic or market conditions, and/or investor behavior that leads investors’ perceptions of value (as reflected in the stock price) to diverge from fundamental value. Price changes may be temporary or last for extended periods.
   
• Risk of Concentrating in the Real Estate Industry: The Fund’s exclusive focus on the real estate industry will subject the Fund to the general risks of direct real estate ownership. The Fund’s performance may bematerially different from the broad U.S. equity market.
   
• Real Estate Investment Risk: The value of securities in the real estate industry can be affected by changes in real estate values and rental income, property taxes, interest rates, and tax and regulatory requirements. Investing in REITs and REIT-like entities involves certain unique risks in addition to those risks associated with investing in the real estate industry in general. REITs and REIT-like entities are dependent upon management skill, may not be diversified, and are subject to heavy cash flow dependency, defaults by borrowers and self-liquidation. REITs also are subject to the possibility of failing to qualify for tax free pass-through of income. Also, because REITs and REIT-like entities typically are invested in a limited number of projects or in a particular market segment, these entities are more susceptible to adverse developments affecting a single project or market segment than more broadly diversified investments.
   
• Interest Rate Risk: Changes in prevailing interest rates affect not only the value of REIT shares but may also impact the market value of the REIT’s investment real estate.
   
• Cyclical Market Risk: The real estate industry tends to be cyclical with periods of relative under-performance and out-performance in comparison to the broad U.S. equity market. Such cycles may adversely affect the value of the Fund’s portfolio.
   
• Recent Market Conditions: The financial crisis in the U.S. and global economies over the past several years, including the European sovereign debt and banking crises, has resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign, and in the net asset values of many mutual funds, including to some extent the Fund. It is uncertain how long these conditions will continue. In addition, global economies and financial markets are becoming increasingly interconnected, which increases the possibilities that conditions in one country or region might adversely impact issuers in a different country or region. The severity or duration of these conditions may also be affected by policy changes made by governments or quasi-governmental organizations.
