Risk [Text Block]

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:

Investor Class Shares | SA U.S. Fixed Income Fund | Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

●Market Risk: The value of securities may go up or down in response to the prospects of individual issuers, general economic or market conditions, pandemics or other national/international health and safety emergencies, war or other conflicts around the globe, and/or investor behavior that leads investors’ perceptions of value (as reflected in the price of the security) to diverge from fundamental value.
Investor Class Shares | SA U.S. Fixed Income Fund | Interest Rate and Related Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]

●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. In addition, fluctuations in interest rates may adversely affect the liquidity of certain fixed-income securities held by the Fund.

Investor Class Shares | SA U.S. Fixed Income Fund | Inflation-Protected Securities Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

●Inflation-Protected Securities Interest Rate Risk: Inflation-protected securities may react differently from other fixed income securities to changes in interest rates. Because interest rates on inflation-protected securities are adjusted for inflation, the values of these securities are not materially affected by inflation expectations. Therefore, the value of inflation-protected securities is anticipated to change in response to changes in “real” interest rates, which represent nominal (stated) interest rates reduced by the expected impact of inflation. Generally, the value of an inflation-protected security will fall when real interest rates rise and will rise when real interest rates fall.

Investor Class Shares | SA U.S. Fixed Income Fund | Inflation-Protected Securities Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

●Inflation-Protected Securities Tax Risk: Any increase in the principal amount of an inflation-protected security may be included for tax purposes in the Fund’s gross income, even though no cash attributable to such gross income has
been received by the Fund. In such an event, the Fund may be required to make annual gross distributions to shareholders that exceed the cash it has otherwise received. To pay such distributions, the Fund may be required to raise cash by selling its investments. The sale of such investments could result in capital gains to the Fund and additional capital gain distributions to shareholders. In addition, adjustments during the taxable year for deflation to an inflation-indexed bond held by the Fund may cause amounts previously distributed to shareholders in the taxable year as income to be characterized as a return of capital.

Investor Class Shares | SA U.S. Fixed Income Fund | Risks of Investing for Inflation Protection [Member]  
Prospectus [Line Items]  
Risk [Text Block]

●Risks of Investing for Inflation Protection: Because the interest and/or principal payments on an inflation-protected security are adjusted periodically for changes in inflation, the income distributed by the Fund may be irregular. Although the U.S. Treasury guarantees to pay at maturity at least the original face value of any inflation-protected securities the Treasury issues, other issuers may not offer the same guarantee. Also, inflation-protected securities, including those issued by the U.S. Treasury, are not protected against deflation. As a result, in a period of deflation, the inflation-protected securities held by the Fund may not pay any income and the Fund may suffer a loss during such periods. While inflation-protected securities are expected to be protected from long-term inflationary trends, short-term increases in inflation may lead to a decline in the Fund’s value. If interest rates rise due to reasons other than inflation, the Fund’s investment in these securities may not be protected to the extent that the increase is not reflected in the securities’ inflation measures. In addition, positive adjustments to principal generally will result in taxable income to the Fund at the time of such adjustments (which generally would be distributed by the Fund as part of its taxable dividends), even though the principal amount is not paid until maturity. The current market value of inflation-protected securities is not guaranteed and will fluctuate.
Investor Class Shares | SA U.S. Fixed Income Fund | Credit Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

●Credit Risk: The risk that the issuer or the guarantor of a fixed income security, or the counterparty to a derivatives contract, repurchase agreement, loan of portfolio securities or other transaction, is unable or unwilling, or is perceived (whether by market participants, ratings agencies, pricing services or otherwise) as unable or unwilling, to make timely principal and/or interest payments, or otherwise honor its obligations. Securities are subject to varying degrees of credit risk, which are often reflected in their credit ratings. The downgrade of the credit rating of a security may decrease its value.

●Income Risk: The Fund’s distributions of income to shareholders may decline when prevailing interest rates fall or if the Fund experiences defaults on debt securities it holds.

Investor Class Shares | SA U.S. Fixed Income Fund | Call Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

●Call Risk: Call risk is the risk that during periods of falling interest rates, an issuer will call or repay a higher-yielding fixed income security before its maturity date, forcing the Fund to reinvest in fixed income securities with lower interest rates than the original obligations.

Investor Class Shares | SA U.S. Fixed Income Fund | Investment Grade Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

●Investment Grade Securities Risk: Fixed income securities commonly are rated by national bond ratings agencies. Securities rated in the lower investment grade rating categories (e.g., BBB by S&P or Fitch or Baa by Moody’s) are considered investment grade securities, but are somewhat riskier than higher rated obligations because they are regarded as having only an adequate capacity to pay principal and interest, and are considered to lack outstanding investment characteristics.

Investor Class Shares | SA U.S. Fixed Income Fund | U.S. Government Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

●U.S. Government Securities Risk: U.S. government guarantees on fixed income securities 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.

Investor Class Shares | SA U.S. Fixed Income Fund | Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

●Sector Risk: Companies with similar characteristics may be grouped together in broad categories called sectors. The Fund may be overweight in certain sectors at various times. To the extent the Fund invests more heavily in a particular sector, its performance will be especially sensitive to any economic, business, regulatory or other developments which generally affect that sector. Individual sectors may underperform other sectors or the market as a whole.

Investor Class Shares | SA U.S. Fixed Income Fund | Banking Concentration Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

●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.

Investor Class Shares | SA U.S. Fixed Income Fund | Financials Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

●Financials Sector Risk: The performance of companies in the financials sector, as traditionally defined, may be adversely impacted by many factors, including, among others, changes in government regulations, economic conditions, and interest rates, credit rating downgrades, adverse public perception, exposure concentration and decreased liquidity in credit markets. The impact of changes in regulation of any individual financial company, or of the financials sector as a whole, cannot be predicted. Cybersecurity incidents and technology malfunctions and failures have become increasingly frequent and have caused significant losses to companies in this sector, which may negatively impact the Fund.

Investor Class Shares | SA U.S. Fixed Income Fund | European Economic Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

●European Economic Risk: The European Union’s (“EU”) Economic and Monetary Union requires member countries to comply with restrictions on interest rates, deficits, debt levels, inflation rates and other factors, each of which may significantly impact every European country. The economies of EU member countries and their trading partners may be adversely affected by changes in the euro’s exchange rate, changes in EU or governmental regulations on trade, and the threat of default or default by an EU member country on its sovereign debt, which could negatively impact the Fund’s investments and cause it to lose money.

Investor Class Shares | SA U.S. Fixed Income Fund | Foreign Government and Supranational Organization Obligations Risk [Member  
Prospectus [Line Items]  
Risk [Text Block]

●Foreign Government and Supranational Organization Obligations Risk: Investments in foreign government obligations are exposed to the direct or indirect consequences of political, social, and economic changes in various countries. There is generally limited legal recourse in the event of a default with respect to foreign government and supranational organization obligations.

Investor Class Shares | SA U.S. Fixed Income Fund | Foreign Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

●Foreign Securities Risk: U.S. dollar-denominated securities of foreign issuers or U.S. subsidiaries or branches of foreign banks involve risks in addition to those associated with comparable U.S. securities. These risks may include social, political or economic instability; nationalization or expropriation of assets; changes in tax policy; and less stringent accounting, auditing, financial reporting, and legal standards and practices.

Investor Class Shares | SA U.S. Fixed Income Fund | Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

●Liquidity Risk: Liquidity risk exists when particular portfolio investments are difficult to purchase or sell. To the extent that the Fund holds illiquid investments, the Fund’s performance may be reduced due to an inability to sell the investments at opportune prices or times. Liquid portfolio investments may become illiquid or less liquid after purchase by the Fund due to low trading volume, adverse investor perceptions, credit tightening and/or other market developments. Liquidity risk includes the risk that the Fund will experience significant net redemptions at a time when it cannot find willing buyers for its portfolio securities or can only sell its portfolio securities at a material loss. Liquidity risk can be more pronounced during periods of market turmoil or economic uncertainty.

Investor Class Shares | SA U.S. Fixed Income Fund | Operational Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

●Operational Risk: Operational risks include human error, changes in personnel, system changes, faults in communication, and failures in systems, technology, or processes and the use of artificial intelligence and machine learning that result in events or circumstances that negatively impact the operations of the Fund and that may adversely impact Fund performance. Various operational events or circumstances are outside the Adviser’s and Sub-Adviser’s control, including instances at third parties. The Fund, the Adviser and Sub-Adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Investor Class Shares | SA U.S. Fixed Income Fund | Cybersecurity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

●Cybersecurity Risk: Cybersecurity breaches may allow an unauthorized party to gain access to Fund assets, customer data, or proprietary information, or cause the Fund and/or its service providers to suffer data corruption or lose operational functionality. Cyber-attacks affecting the Fund, any of its service providers or any issuer in which the Fund invests may adversely impact the Fund.

Investor Class Shares | SA U.S. Fixed Income Fund | Management Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

●Management Risk: The investment techniques and risk analyses applied by the Sub-Adviser may not produce the desired results. Furthermore, legislative, regulatory, or tax restrictions, policies, or developments may affect the investment techniques available to the Sub-Adviser in connection with managing the Fund. There is no guarantee that the investment objective of the Fund will be achieved.

Investor Class Shares | SA U.S. Fixed Income Fund | Large Investor Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

●Large Investor Risk: Ownership of shares of the Fund may be concentrated in one or a few large investors. Such investors may redeem shares in large quantities or on a frequent basis. Redemptions by a large investor may: affect the performance of the Fund; increase realized capital gains; accelerate the realization of taxable income to shareholders; and increase transaction costs and/or other expenses for the Fund.

●Risks of Investing for Inflation Protection: Because the interest and/or principal payments on an inflation-protected security are adjusted periodically for changes in inflation, the income distributed by the Fund may be irregular.

Also, inflation-protected securities, including those issued by the U.S. Treasury, are not protected against deflation. As a result, in a period of deflation, the inflation-protected securities held by the Fund may not pay any income and the Fund may suffer a loss during such periods. While inflation-protected securities are expected to be protected from long-term inflationary trends, short-term increases in inflation may lead to a decline in the Fund’s value. If interest rates rise due to reasons other than inflation, the Fund’s investment in these securities may not be protected to the extent that the increase is not reflected in the securities’ inflation measures. In addition, positive adjustments to principal generally will result in taxable income to the Fund at the time of such adjustments (which generally would be distributed by the Fund as part of its taxable dividends), even though the principal amount is not paid until maturity. The current market value of inflation-protected securities is not guaranteed and will fluctuate.

●Foreign Securities and Currency Risk: Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks may include exposure to less developed or less efficient trading markets; social, political or economic instability; nationalization or expropriation of assets; 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. Values of securities denominated in foreign currencies also may be negatively affected by changes in the exchange rates between the U.S. dollar and foreign currencies.
Investor Class Shares | SA Global Fixed Income Fund | Hedging Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
●Hedging Risk: Foreign currency forward 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 foreign currency forward 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. For example, it is generally not possible to precisely match the foreign currency exposure of such foreign currency forward contracts to the value of the securities involved due to fluctuations in the market values of such securities and cash flows into and out of the Fund between the date a foreign currency forward contract is entered into and the date it expires.
Investor Class Shares | SA Global Fixed Income Fund | Securities Lending Risk [Member]

●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.

Risk [Text Block]
●Small Company Stock Risk: The stocks of small companies may involve more risk 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 their share prices. In addition, small company stocks typically are traded in lower volume, making them more difficult to purchase or sell at the desired time and price or in the desired amount. Generally, the smaller the company size, the greater these risks.
Investor Class Shares | SA U.S. Core Market Fund | Information Technology Sector Risk [Member]

Risk [Text Block]
●Information Technology Sector Risk: The information technology sector (sometimes referred to as the technology sector) includes companies in the software and services, technology hardware and equipment, and semiconductors and semiconductor equipment industry groups. Companies in the information technology sector are subject to rapid obsolescence of existing technology, short product cycles, falling prices and profits, competition from new market entrants, and general economic conditions. Stocks of companies in the information technology sector, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Technological developments, fixed rate pricing, and the ability to retain skilled employees can significantly affect the industries in the information technology sector.

●Derivatives Risk:  Derivatives are instruments, such as futures contracts, and options thereon, whose value is derived from that of other assets, rates or indices. The use of derivatives and other similar investments (referred to herein collectively as “derivatives”) may be considered to carry more risk than other types of investments. When the Fund uses derivatives, the Fund will be directly exposed to the risks of those derivatives. Derivative instruments are subject to a number of risks including counterparty, liquidity, interest rate, market, credit, operational, legal, leverage and management risks, as well as the risk of improper valuation. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and the Fund could lose more than the principal amount invested. Changes in the value of a derivative may also create margin delivery or settlement payment obligations for the Fund.

●U.S. Trade Policy Risk: The U.S. under the current administration has adopted protectionist trade policies, resulting in significant impacts on international trade relations and in certain instances retaliatory actions. There continues to exist significant uncertainty about the future relationship between the U.S. and other countries with respect to trade policies, treaties and tariffs. The imposition of tariffs, trade embargoes or other trade restrictions, or the threat thereof, can disrupt international trade, trigger retaliatory actions, reduce economic growth, increase inflation and adversely affect economies. Any of these factors could depress economic activity and restrict a portfolio company’s access to suppliers or customers and have a material adverse effect on its business, financial condition or operations, which in turn could negatively impact the Fund.

●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. In addition, the Fund’s net asset value is subject to the fluctuations in the net asset value of the DFA Portfolio and, indirectly, the net asset values 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, on the Sub-Adviser’s decisions regarding the allocation of the DFA Portfolio’s assets among the Underlying Funds, and the Sub-Adviser’s selection of securities for the Underlying Funds. The extent to which the investment performance and risks associated with the Fund correlates to those of a particular Underlying Fund will depend upon the extent to which the DFA Portfolio’s assets are allocated from time to time for investment in the Underlying Fund, which will vary. There can be no assurance that the investment objective of the Fund, the DFA Portfolio or any Underlying Fund will be achieved. Duplication of expenses is a risk when a fund invests in other investment companies. When the DFA Portfolio invests in Underlying Funds, investors are subject to their proportionate share of the expenses of these Underlying Funds in addition to the expenses of the DFA Portfolio and the Fund. The cost of investing in the Fund, therefore, may be higher than the cost of investing in a mutual fund that invests directly in individual stocks and bonds. As the DFA Portfolio’s allocation to the Underlying Funds changes from time to time, or to the extent that the expense ratios of the DFA Portfolio or the Underlying Funds change, the operating expenses of the DFA Fund and the Underlying Funds borne by the Fund may increase or decrease.

Additional risks may include exposure to less developed or less efficient trading markets; social, political or economic instability; nationalization or expropriation of assets; 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. Values of securities denominated in foreign currencies also may be negatively affected by changes in the exchange rates between the U.S. dollar and foreign currencies.

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 their share prices. In addition, small company stocks typically are traded in lower volume, making them more difficult to purchase or sell at the desired time and price or in the desired amount. Generally, the smaller the company size, the greater these risks.

cycles, falling prices and profits, competition from new market entrants, and general economic conditions. Stocks of companies in the information technology sector, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Technological developments, fixed rate pricing, and the ability to retain skilled employees can significantly affect the industries in the information technology sector.

When the Fund uses derivatives, the Fund will be directly exposed to the risks of those derivatives. Derivative instruments are subject to a number of risks including counterparty, liquidity, interest rate, market, credit, operational, legal, leverage and management risks, as well as the risk of improper valuation. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and the Fund could lose more than the principal amount invested. Changes in the value of a derivative may also create margin delivery or settlement payment obligations for the Fund.

●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, more vulnerable to market manipulation and more difficult to value, 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. Stock markets in many emerging market countries are relatively small, expensive to trade and risky. Foreigners are often limited in their ability to invest in, and withdraw assets from, these markets. Additional restrictions may be imposed under emergency conditions. These risks may be magnified in countries that are frontier markets.
Investor Class Shares | SA Emerging Markets Value Fund | China Investments Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
●China Investments Risk: There are special risks associated with investments in China, Hong Kong, and Taiwan. China, Hong Kong, and Taiwan are highly interconnected and interdependent, with relationships built on trade, finance, culture, and politics. Despite prior economic and trade reforms and the prior expansion of private ownership of companies in certain sectors, the Chinese government still exercises substantial influence over many aspects of the private sector and may own or control many companies, including by embedding Chinese Communist Party or People’s Armed Forces Department personnel in Chinese companies. In addition, the Chinese government continues to maintain a major role in economic policy making and may alter or discontinue economic or trade reforms at any time. Investing in China involves risks of losses due to expropriation, nationalization, confiscation of assets and property, and the imposition of restrictions on foreign investments and on repatriation of capital invested.

 

Investments in China, Hong Kong, and Taiwan are also subject to the risk of escalating tensions and deteriorating relations with the U.S. as economic and strategic competition between the U.S. and China intensifies, which could result in further tariffs, trade restrictions, sanctions, or other actions that adversely impact the value of such investments. A reduction in spending on Chinese products and services, supply chain diversification or the institution of additional tariffs or other trade barriers, including as a result of heightened trade tensions between China and the United States may also have an adverse impact on the Chinese economy. In addition, investments in Taiwan could be adversely affected by its political and economic relationship with China. Certain securities issued by companies located or operating in China, such as China A-shares, are also subject to trading restrictions, quota limitations and less market liquidity, which could pose risks to a fund investing in such securities. In addition, investments in special structures that utilize contractual arrangements to provide exposure to certain Chinese companies, known as variable interest entities (“VIEs”), that operate in sectors in which China restricts and/or prohibits foreign investments may present additional risks. The Chinese government’s acceptance of the VIE structure is evolving. It is uncertain whether Chinese officials and regulators will withdraw their acceptance of the structure generally, or with respect to certain industries, or whether Chinese courts or arbitration bodies would decline to enforce the contractual rights of foreign investors, each of which would likely have significant, detrimental, and possibly permanent losses on the value of such investments.

●Indian Market and India Region Risk:  Government actions, bureaucratic obstacles and inconsistent economic and tax reform policies within the Indian government have had a significant effect on the economy and could adversely affect market conditions, deter economic growth and reduce the profitability of private enterprises. Global factors and foreign actions may inhibit the flow of foreign capital on which India is dependent to sustain its growth. Large portions of many Indian companies remain in the hands of their founders (including members of their families) which may have weaker and less transparent corporate governance and increase risk of loss or unequal treatment for investors. In addition, the threat of aggression in the region could hinder development of the Indian economy, and escalating tensions could impact the broader region, including China.

●Real Estate and REIT 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 federally 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.

●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, more vulnerable to market manipulation and more difficult to value, 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. Stock markets in many emerging market countries are relatively small, expensive to trade and risky. Foreigners are often limited in their ability to invest in, and withdraw assets from, these markets. Additional restrictions may be imposed under emergency conditions. These risks may be magnified in countries that are frontier markets.

●Interest Rate Risk: Generally, when market interest rates rise, the value of fixed income securities declines, and vice versa. Investing in such securities means that the Fund’s NAV will tend to decline if market interest rates rise. Interest rate risk is generally greater for fixed-income securities with longer maturities or durations. In addition, fluctuations in interest rates may adversely affect the liquidity of certain fixed-income securities held by the Fund.

●Affiliated Fund Risk: In managing a Fund that invests in Underlying SA Funds, the Adviser will have the authority to select and substitute the Underlying SA Funds. The Adviser may be subject to potential conflicts of interest in allocating the Fund’s assets among the various Underlying SA Funds because the fees payable to it by some of the Underlying SA Funds are higher than the fees payable by other Underlying SA Funds and because the Adviser is also responsible for managing, administering, and providing shareholder servicing to the Underlying SA Funds.

●Investment in Underlying SA Funds Risk: The investment performance of the Fund is affected by the investment performance of the Underlying SA Funds in which the Fund invests. In addition, the Fund’s net asset value (“NAV”) per share is subject to fluctuations in the NAVs of the Underlying SA Funds in which it invests. The Fund is also subject to the risks associated with the securities in which the Underlying SA Funds invest and the ability of the Fund to achieve its investment objective depends on the ability of the Underlying SA Funds to meet their investment objectives and on the Adviser’s decisions regarding the allocation of the Fund’s assets among the Underlying SA Funds. The extent to which the investment performance and risks associated with the Fund correlates to those of a particular Underlying SA Fund will depend upon the extent to which the Fund’s assets are allocated from time to time for investment in the Underlying SA Fund, which will vary. There can be no assurance that the investment objective of the Fund or any Underlying SA Fund will be achieved. When the Fund invests in Underlying SA Funds, the Fund will indirectly bear its proportionate share of the fees and expenses of these Underlying SA Funds in addition to the direct fees and expenses of the Fund. The cost of investing in the Fund, therefore, may be higher than the cost of investing in a mutual fund that invests directly in individual stocks and bonds. As the Fund’s allocation to the Underlying SA Funds changes from time to time, or to the extent that the expense ratios of the Underlying SA Funds change, the operating expenses of the Underlying SA Funds borne by the Fund may increase or decrease.

●Allocation Risk: The Fund’s ability to achieve its investment objective depends upon the Adviser’s ability to develop an appropriate asset class allocation model and select an appropriate mix and weighting of Underlying SA Funds. There is a risk that the Adviser’s evaluations and assumptions regarding asset classes, market segments or selection of Underlying SA Funds fails to produce the intended results which could cause the Fund to underperform other funds with a similar investment objective.

●Capitalization Risk: Larger, more established companies may be unable to respond quickly to competitive challenges, such as changes in technology and consumer tastes. 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 stocks of small companies may involve more risk 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 their share prices. In addition, small company stocks typically are traded in lower volume, making them more difficult to purchase or sell at the desired time and price or in the desired amount. Generally, the smaller the company size, the greater these risks.
