Such equity investments may include exchange traded funds (&amp;#8220;ETFs&amp;#8221;), futures and other instruments with similar economic exposures. The Fund intends to invest in companies with public stock market capitalizations that are larger than $500 million at the time of investment, and in at least three foreign countries. &lt;br /&gt;&lt;br /&gt;
The Fund expects to invest a substantial portion of its assets in the securities of issuers located in the developed countries of Western Europe and in Japan, but may also invest in securities of issuers located in Australia, Canada, New Zealand and in emerging countries. From time to time, the Fund&amp;#8217;s investments in a particular developed country may exceed 25% of its investment portfolio. The Fund is &amp;#8220;strategic&amp;#8221; in that it seeks to provide investors with access to the long term investment opportunity of the international markets. &lt;br /&gt;&lt;br /&gt;
The Fund&amp;#8217;s investments are selected using a strong valuation discipline to purchase what the Investment Adviser believes are well-positioned, cash-generating businesses run by shareholder-oriented management teams. &lt;br /&gt;&lt;br /&gt;
The Fund may also invest in fixed income securities, such as government, corporate and bank debt obligations.</rr:StrategyNarrativeTextBlock>

Foreign risk also involves the risk of negative foreign currency rate fluctuations, which may cause the value of securities denominated in such foreign currency (or other instruments through which the Fund has exposure to foreign currencies) to decline in value. Currency exchange rates may fluctuate significantly over short periods of time.

The Quality theme assesses both firm and management quality.

The longer the duration of the Fund (or an individual debt security), the more sensitive its market price to changes in interest rates. For example, if market interest rates increase by 1%, the market price of a debt security with a positive duration of 3 will generally decrease by approximately 3%. Conversely, a 1% decline in market interest rates will generally result in an increase of approximately 3% of that security&amp;#8217;s market price.</rr:StrategyNarrativeTextBlock>

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the (&amp;#8220;FDIC&amp;#8221;) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investment in the Fund involves substantial risks which prospective investors should consider carefully before investing.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Credit/Default Risk.&lt;/b&gt;&amp;nbsp;&amp;nbsp;An issuer or guarantor of fixed income securities or instruments held by the Fund may default on its obligation to pay interest and repay principal or default on any other obligation. Additionally, the credit quality of securities may deteriorate rapidly, which may impair the Fund&amp;#8217;s liquidity and cause significant net asset value (&amp;#8220;NAV&amp;#8221;) deterioration.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Derivatives Risk.&lt;/b&gt;&amp;nbsp;&amp;nbsp;Loss may result from the Fund&amp;#8217;s investments in forwards and other derivative instruments. These instruments may be illiquid, difficult to price and leveraged so that small changes may produce disproportionate losses to the Fund. Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligation.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Foreign and Emerging Countries Risk.&lt;/b&gt;&amp;nbsp;&amp;nbsp;Foreign securities may be subject to risk of loss because of more or less foreign government regulation, less public information and less economic, political and social stability in the countries in which the Fund invests. Loss may also result from the imposition of exchange controls, confiscations and other government restrictions, or from problems in registration, settlement or custody. Foreign risk also involves the risk of negative foreign currency rate fluctuations, which may cause the value of securities denominated in such foreign currency (or other instruments through which the Fund has exposure to foreign currencies) to decline in value. Currency exchange rates may fluctuate significantly over short periods of time. To the extent that the Fund also invests in securities of issuers located in emerging markets, these risks may be more pronounced.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Interest Rate Risk.&lt;/b&gt;&amp;nbsp;&amp;nbsp;When interest rates increase, fixed income securities or instruments held by the Fund will generally decline in value. Long-term fixed income securities or instruments will normally have more price volatility because of this risk than short-term fixed income securities or instruments.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Mortgage-Backed and Other Asset-Backed Risk.&lt;/b&gt;&amp;nbsp;&amp;nbsp;Mortgage-related and other asset-backed securities are subject to certain additional risks, including &amp;#8220;extension risk&amp;#8221; (i.e., in periods of rising interest rates, issuers may pay principal later than expected) and &amp;#8220;prepayment risk&amp;#8221; (i.e., in periods of declining interest rates, issuers may pay principal more quickly than expected, causing the Fund to reinvest proceeds at lower prevailing interest rates). Mortgage-backed securities offered by non-governmental issuers are subject to other risks as well, including failures of private insurers to meet their obligations and unexpectedly high rates of default on the mortgages backing the securities. Other asset-backed securities are subject to risks similar to those associated with mortgage-backed securities, as well as risks associated with the nature and servicing of the assets backing the securities. Asset-backed securities may not have the benefit of a security interest in collateral comparable to that of mortgage assets, resulting in additional credit risk.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;U.S. Government Securities Risk.&lt;/b&gt;&amp;nbsp;&amp;nbsp;The U.S. government may not provide financial support to U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law. U.S. Government Securities issued by the Federal National Mortgage Association (&amp;#8220;Fannie Mae&amp;#8221;), Federal Home Loan Mortgage Corporation (&amp;#8220;Freddie Mac&amp;#8221;) and the Federal Home Loan Banks are neither issued nor guaranteed by the U.S. Treasury and, therefore, are not backed by the full faith and credit of the United States. The maximum potential liability of the issuers of some U.S. Government Securities held by the Fund may greatly exceed their current resources, including any legal right to support from the U.S. Treasury. It is possible that these issuers will not have the funds to meet their payment obligations in the future.</rr:RiskNarrativeTextBlock>

The Fund&amp;#8217;s equity investment process involves: (1) using multiple industry-specific valuation metrics to identify real economic value and company potential in stocks, screened by valuation, profitability and business characteristics; (2) conducting in-depth company research and assessing overall business quality; and (3) buying those securities that a sector portfolio manager recommends, taking into account feedback from the rest of the portfolio management team. The Investment Adviser may decide to sell a position for various reasons, including valuation and price considerations, readjustment of the Investment Adviser&amp;#8217;s outlook based on subsequent events, the Investment Adviser&amp;#8217;s ongoing assessment of the quality and effectiveness of management, if new investment ideas offer the potential for better risk/reward profiles than existing holdings, or for risk management purposes. In addition, the Investment Adviser may sell a position in order to meet shareholder redemptions.&lt;br/&gt;&lt;br/&gt;The Fund may also invest in fixed income securities, such as government, corporate and bank debt obligations.</rr:StrategyNarrativeTextBlock>

Although the Fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Fund.

There can be no assurance that the Fund will achieve its investment objective.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Banking Industry Risk.&lt;/b&gt; &amp;nbsp;An adverse development in the banking industry may affect the value of the Fund&amp;#8217;s investments more than if the Fund were not invested to such a degree in the banking industry. Banks may be particularly susceptible to certain economic factors such as interest rate changes, adverse developments in the real estate market, fiscal, regulatory and monetary policy and general economic cycles.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Credit/Default Risk.&lt;/b&gt; &amp;nbsp;An issuer or guarantor of a security held by the Fund, or a bank or other financial institution that has entered into a repurchase agreement with the Fund, may default on its obligation to pay interest and repay principal or default on any other obligation. Additionally, the credit quality of securities may deteriorate rapidly, which may impair the Fund&amp;#8217;s liquidity and cause significant NAV deterioration.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Foreign Risk.&lt;/b&gt; &amp;nbsp;Foreign securities may be subject to risk of loss because of more or less foreign government regulation, less public information and less economic, political and social stability in the countries in which the Fund invests. Loss may also result from the imposition of confiscations and other government restrictions, or from problems in registration, settlement or custody.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Interest Rate Risk.&lt;/b&gt; &amp;nbsp;When interest rates increase, the Fund&amp;#8217;s yield will tend to be lower than prevailing market rates, and the market value of its securities or instruments may also be adversely affected. A low interest rate environment poses additional risks to the Fund, because low yields on the Fund&amp;#8217;s portfolio holdings may have an adverse impact on the Fund&amp;#8217;s ability to provide a positive yield to its shareholders, pay expenses out of Fund assets, or, at times, maintain a stable $1.00 share price.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Liquidity Risk.&lt;/b&gt; &amp;nbsp;The Fund may make investments that are illiquid or that may become less liquid in response to market developments or adverse investor perceptions. Illiquid investments may be more difficult to value. The liquidity of portfolio securities can deteriorate rapidly due to credit events affecting issuers or guarantors, such as a credit rating downgrade, or due to general market conditions or a lack of willing buyers. An inability to sell one or more portfolio positions, or selling such positions at an unfavorable time and/or under unfavorable conditions, can adversely affect the Fund&amp;#8217;s ability to maintain a stable $1.00 share price. Liquidity risk may also refer to the risk that the Fund will not be able to pay redemption proceeds within the allowable time period because of unusual market conditions, an unusually high volume of redemption requests, or other reasons. Certain shareholders may own or control a significant percentage of the Fund&amp;#8217;s shares, and redemptions by these shareholder of their Fund shares may further increase the Fund&amp;#8217;s liquidity risk and may adversely impact the Fund&amp;#8217;s NAV.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Market Risk.&lt;/b&gt; &amp;nbsp;The market value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Regulatory Risk.&lt;/b&gt; &amp;nbsp;The Securities and Exchange Commission (&amp;#8220;SEC&amp;#8221;) and other government agencies continue to review the regulation of money market funds, and may take additional regulatory action in the future. These changes may affect the Fund&amp;#8217;s ability to implement its investment strategies, operations and/or return potential.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Stable NAV Risk.&lt;/b&gt; &amp;nbsp;The Fund may not be able to maintain a stable $1.00 share price at all times. If any money market fund fails to maintain a stable NAV (or if there is a perceived threat of such a failure), other money market funds, including the Fund, could be subject to increased redemption activity, which could adversely affect the Fund&amp;#8217;s NAV. Shareholders of the Fund should not rely on or expect the Investment Adviser or an affiliate to purchase distressed assets from the Fund, make capital infusions into the Fund, enter into capital support agreements with the Fund or take other actions to help the Fund maintain a stable $1.00 share price.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;U.S. Government Securities Risk.&lt;/b&gt; &amp;nbsp;The U.S. government may not provide financial support to U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law. U.S. Government Securities issued by the Federal National Mortgage Association (&amp;#8220;Fannie Mae&amp;#8221;), Federal Home Loan Mortgage Corporation (&amp;#8220;Freddie Mac&amp;#8221;) and Federal Home Loan Banks are neither issued nor guaranteed by the U.S. Treasury and, therefore, are not backed by the full faith and credit of the United States. The maximum potential liability of the issuers of some U.S. Government Securities held by the Fund may greatly exceed their current resources, including any legal right to support from the U.S. Treasury. It is possible that issuers of U.S. Government Securities will not have the funds to meet their payment obligations in the future.</rr:RiskNarrativeTextBlock>

As of April 1, 2013, the capitalization range of the Russell Midcap&amp;#174; Value Index was between approximately $400.5 million and $29.8 billion. Although the Fund will invest primarily in publicly traded U.S. securities, it may invest in foreign securities, including securities of issuers in countries with emerging markets or economies (&amp;#8220;emerging countries&amp;#8221;) and securities quoted in foreign currencies.&lt;br/&gt;&lt;br/&gt;The Fund&amp;#8217;s equity investment process involves: (1) using multiple industry-specific valuation metrics to identify real economic value and company potential in stocks, screened by valuation, profitability and business characteristics; (2) conducting in-depth company research and assessing overall business quality; and (3) buying those securities that a sector portfolio manager recommends, taking into account feedback from the rest of the portfolio management team. The Investment Adviser may decide to sell a position for various reasons, including valuation and price considerations, readjustment of the Investment Adviser&amp;#8217;s outlook based on subsequent events, the Investment Adviser&amp;#8217;s ongoing assessment of the quality and effectiveness of management, if new investment ideas offer the potential for better risk/reward profiles than existing holdings, or for risk management purposes. In addition, the Investment Adviser may sell a position in order to meet shareholder redemptions.&lt;br/&gt;&lt;br/&gt;The Fund may also invest in companies with public stock market capitalizations outside the range of companies constituting the Russell Midcap&amp;#174; Value Index at the time of investment and in fixed income securities, such as government, corporate and bank debt obligations.</rr:StrategyNarrativeTextBlock>

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01May2012_30Apr2013S000035992_Member">The Fund seeks to achieve investment results that approximate the performance of the GS Global Markets Navigator Index&lt;sup style="FONT-SIZE: 85%; VERTICAL-ALIGN: top"&gt;TM&lt;/sup&gt;. The Index is comprised of, and allocates exposure to, a set of underlying indices representing various global asset classes including, but not limited to, global equity and global fixed income (the &amp;#8220;Underlying Indices&amp;#8221;). Using a proprietary methodology (the &amp;#8220;Methodology&amp;#8221;) developed by Goldman, Sachs &amp;amp; Co. (the &amp;#8220;Index Provider&amp;#8221;), the Index seeks to provide exposure to price momentum of these global assets, or Underlying Indices, by reflecting a combination of index weightings that is determined in part by the respective three-, six- and nine-month historical returns of these global assets. Momentum investing seeks growth of capital by investing in assets that have exhibited trends in price performance over recent selected time periods. The Methodology also considers maximum and minimum weightings requirements and volatility controls. The Index is generally rebalanced monthly but may be rebalanced as frequently as daily if certain volatility controls are triggered. The Index Provider may, in its discretion, make changes to the Index, its methodology or quantitative techniques, or use other methodologies or quantitative techniques that are based on the Index Provider&amp;#8217;s proprietary research. The Index is sponsored by the Index Provider, an affiliate of the Fund&amp;#8217;s Investment Adviser, and calculated by Structured Solutions AG (the &amp;#8220;Calculation Agent&amp;#8221;). &lt;br /&gt;&lt;br /&gt; Given the Fund&amp;#8217;s objective of attempting to track the Index, the Fund does not follow traditional methods of active investment management, which may involve buying and selling securities based upon analysis of economic and market factors. Instead, the Fund will invest in securities and other financial instruments that provide exposure to the Underlying Indices in approximately the same weighting that such Underlying Indices have within the Index at the applicable time. The Investment Adviser will, however, be responsible for, among other things, investment selection, timing of trading and counterparty selection. &lt;br /&gt;&lt;br /&gt; The Fund&amp;#8217;s portfolio of investments may include, among other instruments, futures (including index futures), swaps, structured notes, other derivatives and investment companies (including exchange-traded funds (&amp;#8220;ETFs&amp;#8221;)) that provide exposure to a broad spectrum of asset classes, including but not limited to, equities (US and non-US companies) and high quality fixed income (US and non-US developed country government and government agency securities). The Fund may also invest directly in equity securities and US and non-US developed country government and government agency fixed income securities. The percentage of the portfolio exposed to any asset class or geographic region will vary from time to time as the weightings of the Underlying Indices within the Index change, and the Fund may not be invested in each asset class at all times. Moreover, the Fund may at times be more heavily invested in certain asset classes, such as U.S. equity or U.S. fixed income. As a result of the Fund&amp;#8217;s use of derivatives, and/or in an effort to mitigate portfolio volatility, the Fund may also hold significant amounts of U.S. Treasury, short-term, or other fixed income investments, including money market funds and repurchase agreements or cash, and at times may invest up to 100% of its assets in such investments. The Fund may also engage in foreign currency transactions (including forward contracts) for hedging purposes or to seek to increase total return. To the extent the Index allocates exposure to commodity-related Underlying Indices in the future, the Fund may invest in instruments that provide exposure to commodities. Although it does not currently intend to do so, the Fund may also invest through a wholly-owned subsidiary, which would be advised by the Investment Adviser and would seek to gain commodities exposure. &lt;br /&gt;&lt;br /&gt; The Fund will not invest more than 25% of the value of its total assets in the securities of one or more issuers conducting their principal business activities in the same industry, except that, to the extent that an industry represents 20% or more of the Fund&amp;#8217;s index (currently the Index) at the time of investment, the Fund may invest up to 35% of its assets in that industry. &lt;br /&gt;&lt;br /&gt; THE FUND IS NON-DIVERSIFIED UNDER THE INVESTMENT COMPANY ACT OF 1940, AS AMENDED (&amp;#8220;INVESTMENT COMPANY ACT&amp;#8221;), AND MAY INVEST A LARGER PERCENTAGE OF ITS ASSETS IN FEWER ISSUERS THAN DIVERSIFIED MUTUAL FUNDS.</rr:StrategyNarrativeTextBlock>

  <rr:RiskNarrativeTextBlock contextRef="Duration_01May2012_30Apr2013S000035992_Member">Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (&amp;#8220;FDIC&amp;#8221;) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investment in the Fund involves substantial risks which prospective investors should consider carefully before investing.&lt;br/&gt;&lt;br/&gt; &lt;b&gt;Absence of Regulation&lt;/b&gt;.&amp;nbsp;&amp;nbsp;The Fund engages in over-the-counter (&amp;#8220;OTC&amp;#8221;) transactions, which trade in a dealer network, rather than on an exchange. In general, there is less governmental regulation and supervision of transactions in the OTC markets than of transactions entered into on organized exchanges.&lt;br /&gt;&lt;br /&gt; &lt;b&gt;Credit/Default Risk&lt;/b&gt;.&amp;nbsp;&amp;nbsp;An issuer or guarantor of fixed income securities or instruments held by the Fund (which may have low credit ratings) may default on its obligation to pay interest and repay principal or default on any other obligation. Additionally, the credit quality of securities may deteriorate rapidly, which may impair the Fund&amp;#8217;s liquidity and cause significant deterioration in net asset value (&amp;#8220;NAV&amp;#8221;). To the extent that the Fund invests in non-investment grade fixed income securities, these risks will be more pronounced.&lt;br /&gt;&lt;br /&gt; &lt;b&gt;Derivatives Risk&lt;/b&gt;.&amp;nbsp;&amp;nbsp;Loss may result from the Fund&amp;#8217;s investments in forwards, futures, swaps, structured securities and other derivative instruments. These instruments may be leveraged so that small changes may produce disproportionate losses to the Fund. Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligation.&lt;br /&gt;&lt;br /&gt; &lt;b&gt;Expenses Risk&lt;/b&gt;.&amp;nbsp;&amp;nbsp;By investing in pooled investment vehicles (including investment companies and ETFs), partnerships and REITs indirectly through the Fund, the investor will incur a proportionate share of the expenses of those other pooled investment vehicles, partnerships and REITs held by the Fund (including operating costs and investment management fees), in addition to the expenses of the Fund.&lt;br /&gt;&lt;br /&gt; &lt;b&gt;Foreign and Emerging Countries Risk&lt;/b&gt;.&amp;nbsp;&amp;nbsp;Foreign securities may be subject to risk of loss because of more or less foreign government regulation, less public information and less economic, political and social stability in the countries in which the Fund invests. Loss may also result from the imposition of exchange controls, confiscations and other government restrictions, or from problems in registration, settlement or custody. Foreign risk also involves the risk of negative foreign currency rate fluctuations, which may cause the value of securities denominated in such foreign currency (or other instruments through which the Fund has exposure to foreign currencies) to decline in value. Currency exchange rates may fluctuate significantly over short periods of time. To the extent that the Fund also invests in issuers located in emerging markets, these risks may be more pronounced.&lt;br /&gt;&lt;br /&gt; &lt;b&gt;Index/Methodology Risk&lt;/b&gt;.&amp;nbsp;&amp;nbsp;The Index Provider relies on third party data and a Methodology it believes to be reliable in constructing the Index, but it does not guarantee the accuracy of such third party data or the Methodology. There can be no assurance that the Methodology will correctly forecast the risk of particular instruments or asset classes or make effective tactical decisions. The Methodology may direct the Index&amp;#8217;s allocations to an instrument or asset class that underperforms other instruments or asset classes. The Methodology may not achieve its goals of mitigating volatility and modulating risk. If the Index&amp;#8217;s daily volatility control is triggered, the Methodology may reallocate the Index into lower-risk assets, such as cash. By seeking to track the Index when the daily volatility control is triggered, the Fund may underperform in comparison to the general securities markets and/or other asset classes. The Index is new and has a limited performance history. Any new index is subject to errors in its construction.&lt;br /&gt;&lt;br /&gt; &lt;b&gt;Industry Concentration Risk&lt;/b&gt;.&amp;nbsp;&amp;nbsp;The Fund will not invest more than 25% of the value of its total assets in the securities of one or more issuers conducting their principal business activities in the same industry, except that, to the extent that an industry represents 20% or more of the Fund&amp;#8217;s index (currently the Index) at the time of investment, the Fund may invest up to 35% of its assets in that industry. Concentrating Fund investments in issuers conducting business in the same industry will subject the Fund to a greater risk of loss as a result of adverse economic, business or other developments affecting that industry than if its investments were not so concentrated.&lt;br /&gt;&lt;br /&gt; &lt;b&gt;Interest Rate Risk&lt;/b&gt;.&amp;nbsp;&amp;nbsp;When interest rates increase fixed income securities or instruments held by the Fund will generally decline in value. Long-term fixed income securities will normally have more price volatility because of this risk than short-term fixed income securities or instruments.&lt;br /&gt;&lt;br /&gt; &lt;b&gt;Investment Style Risk&lt;/b&gt;.&amp;nbsp;&amp;nbsp;The Index is intended to provide exposure to price momentum of certain U.S., international, developed and emerging equity markets, commodity markets, real estate markets and fixed income assets, and as a result the Index may be more volatile than a more broadly based conventional index. The momentum-based investment style employed by the Fund may fall out of favor from time to time, depending upon market and economic conditions as well as investor sentiment. The Fund may outperform or underperform other funds that invest in similar asset classes but employ different investment styles.&lt;br /&gt;&lt;br /&gt; &lt;b&gt;Leverage Risk&lt;/b&gt;.&amp;nbsp;&amp;nbsp;The use of derivatives may result in leverage, which can magnify the effects of changes in the value of the Fund&amp;#8217;s investments and make it more volatile. The use of leverage may cause the Fund to liquidate portfolio positions to satisfy its obligations or to meet asset segregation requirements when it may not be advantageous to do so. The use of leverage by the Fund can substantially increase the adverse impact to which the Fund&amp;#8217;s investment portfolio may be subject.&lt;br /&gt;&lt;br /&gt; &lt;b&gt;Liquidity Risk&lt;/b&gt;.&amp;nbsp;&amp;nbsp;The Fund may make investments that may be illiquid or that may become less liquid in response to market developments or adverse investor perceptions. Illiquid investments may be more difficult to value. Liquidity risk may also refer to the risk that the Fund will not be able to pay redemption proceeds within the allowable time period because of unusual market conditions, an unusually high volume of redemption requests or other reasons. To meet redemption requests, the Fund may be forced to sell securities, at an unfavorable time and/or under unfavorable conditions.&lt;br /&gt;&lt;br /&gt; &lt;b&gt;Market Risk&lt;/b&gt;.&amp;nbsp;&amp;nbsp;The value of the instruments in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets.&lt;br /&gt;&lt;br /&gt; &lt;b&gt;Non-Diversification Risk&lt;/b&gt;.&amp;nbsp;&amp;nbsp;The Fund is non-diversified, meaning that it is permitted to invest a larger percentage of its assets in fewer issuers than a diversified mutual fund. Thus, the Fund may be more susceptible to adverse developments affecting any single issuer held in its portfolio, and may be more susceptible to greater losses because of these developments.&lt;br /&gt;&lt;br /&gt; &lt;b&gt;Sovereign Risk&lt;/b&gt;.&amp;nbsp;&amp;nbsp;An issuer of non-U.S. sovereign debt, such as Germany or Japan, or the governmental authorities that control the repayment of the debt, may be unable or unwilling to repay the principal or interest when due. This may result from political or social factors, the general economic environment of a country, levels of foreign debt or foreign currency exchange rates.&lt;br /&gt;&lt;br /&gt; &lt;b&gt;Swaps Risk&lt;/b&gt;.&amp;nbsp;&amp;nbsp;In a standard &amp;#8220;swap&amp;#8221; transaction, two parties agree to exchange the returns, differentials in rates of return or some other amount earned or realized on the &amp;#8220;notional amount&amp;#8221; of predetermined investments or instruments, which may be adjusted for an interest factor. Swaps can involve greater risks than direct investment in securities, because swaps may be leveraged and are subject to counterparty risk (e.g., the risk of a counterparty&amp;#8217;s defaulting on the obligation or bankruptcy), credit risk and pricing risk (i.e., swaps may be difficult to value). Swaps may also be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.&lt;br /&gt;&lt;br /&gt; &lt;b&gt;Tracking Error Risk&lt;/b&gt;.&amp;nbsp;&amp;nbsp;The Fund&amp;#8217;s portfolio composition and performance may not match, and may vary substantially from, that of the Index for any period of time, in part because there may be a delay in the Fund&amp;#8217;s implementation of any changes to the composition of the Index. Unlike the Fund, the returns of the Index are not reduced by investment and other operating expenses, including the trading costs associated with implementing changes to its portfolio of investments.&lt;br /&gt;&lt;br /&gt; &lt;b&gt;Treasury Inflation Protected Securities Risk&lt;/b&gt;.&amp;nbsp;&amp;nbsp;The value of TIPS generally fluctuates in response to inflationary concerns. As inflationary expectations increase, TIPS will become more attractive, because they protect future interest payments against inflation. Conversely, as inflationary concerns decrease, TIPS will become less attractive and less valuable.&lt;br /&gt;&lt;br /&gt; &lt;b&gt;U.S. Government Securities Risk&lt;/b&gt;.&amp;nbsp;&amp;nbsp;The U.S. government may not provide financial support to U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law. U.S. Government securities issued by the Federal National Mortgage Association (&amp;#8220;Fannie Mae&amp;#8221;), Federal Home Loan Mortgage Corporation (&amp;#8220;Freddie Mac&amp;#8221;) and the Federal Home Loan Banks are neither issued nor guaranteed by the U.S. Treasury and, therefore, are not backed by the full faith and credit of the United States.

The Fund seeks to achieve its investment objective by investing in a diversified portfolio of equity investments that are considered by the Investment Adviser to be strategically positioned for long-term growth. Although the Fund invests primarily in publicly traded U.S. securities, it may invest up to 25% of its Total Assets in foreign securities, including securities of issuers in countries with emerging markets or economies (&amp;#8220;emerging countries&amp;#8221;) and securities quoted in foreign currencies.&lt;br/&gt;&lt;br/&gt;The Fund&amp;#8217;s fundamental equity growth investment process involves evaluating potential investments based on specific characteristics believed to indicate a high-quality business with sustainable growth, including strong business franchises, favorable long-term prospects, and excellent management. The Investment Adviser will also consider valuation of companies when determining whether to buy and/or sell securities. The Investment Adviser may decide to sell a position for various reasons, including when a company&amp;#8217;s fundamental outlook deteriorates, because of valuation and price considerations, for risk management purposes, or when a company is deemed to be misallocating capital or a company no longer fits within the Fund&amp;#8217;s definition of a mid cap company. In addition, the Investment Adviser may sell a position in order to meet shareholder redemptions.</rr:StrategyNarrativeTextBlock>

  <rr:RiskNarrativeTextBlock contextRef="Duration_01May2012_30Apr2013S000009360_MemberServiceShares_Member">Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (&amp;#8220;FDIC&amp;#8221;) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investment in the Fund involves substantial risks which prospective investors should consider carefully before investing.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Investment Style Risk.&lt;/b&gt;&amp;nbsp;&amp;nbsp;Different investment styles (e.g., &amp;#8220;growth,&amp;#8221; &amp;#8220;value&amp;#8221; or &amp;#8220;quantitative&amp;#8221;) tend to shift in and out of favor depending upon market and economic conditions and investor sentiment. The Fund may outperform or underperform other funds that invest in similar asset classes but employ different investment styles.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Market Risk.&lt;/b&gt;&amp;nbsp;&amp;nbsp;The value of instruments in which the Fund invests may go up or down in response to prospects of individual companies, particular sectors or governments and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Mid-Cap and Small-Cap Risk.&lt;/b&gt;&amp;nbsp;&amp;nbsp;Investments in mid-capitalization and small-capitalization companies involve greater risks than those associated with larger, more established companies. These securities may be subject to more abrupt or erratic price movements and may lack sufficient market liquidity, and these issuers often face greater business risks.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Stock Risk.&lt;/b&gt;&amp;nbsp;&amp;nbsp;Stock prices have historically risen and fallen in periodic cycles. U.S. and foreign stock markets have experienced periods of substantial price volatility in the past and may do so again in the future.</rr:RiskNarrativeTextBlock>

The Fund&amp;#8217;s fundamental equity growth investment process involves evaluating potential investments based on specific characteristics believed to indicate a high-quality business with sustainable growth, including strong business franchises, favorable long-term prospects, and excellent management. The Investment Adviser will also consider valuation of companies when determining whether to buy and/or sell securities. The Investment Adviser may decide to sell a position for various reasons including when a company&amp;#8217;s fundamental outlook deteriorates, because of valuation and price considerations, for risk management purposes or when a company is deemed to be misallocating capital.

The Fund&amp;#8217;s fundamental equity growth investment process involves evaluating potential investments based on specific characteristics believed to indicate a high-quality business with sustainable growth, including strong business franchises, favorable long-term prospects, and excellent management. The Investment Adviser will also consider valuation of companies when determining whether to buy and/or sell securities. The Investment Adviser may decide to sell a position for various reasons including when a company&amp;#8217;s fundamental outlook deteriorates, because of valuation and price considerations, for risk management purposes or when a company is deemed to be misallocating capital.

Although the Fund will invest primarily in publicly traded U.S. securities, it may invest in foreign securities, including securities quoted in foreign currencies.&lt;br/&gt;&lt;br/&gt;The Fund seeks its investment objective by investing in value opportunities that the Investment Adviser defines as companies with identifiable competitive advantages whose intrinsic value is not reflected in the stock price. The Fund&amp;#8217;s equity investment process involves: (1) using multiple industry-specific valuation metrics to identify real economic value and company potential in stocks, screened by valuation, profitability and business characteristics; (2) conducting in-depth company research and assessing overall business quality; and (3) buying those securities that a sector portfolio manager recommends, taking into account feedback from the rest of the portfolio management team. The Investment Adviser may decide to sell a position for various reasons, including valuation and price considerations, readjustment of the Investment Adviser&amp;#8217;s outlook based on subsequent events, the Investment Adviser&amp;#8217;s ongoing assessment of the quality and effectiveness of management, if new investment ideas offer the potential for better risk/reward profiles than existing holdings, or for risk management purposes. In addition, the Investment Adviser may sell a position in order to meet shareholder redemptions.&lt;br/&gt;&lt;br/&gt;The Fund may also invest in fixed income securities, such as government, corporate and bank debt obligations.</rr:StrategyNarrativeTextBlock>

  <rr:RiskNarrativeTextBlock contextRef="Duration_01May2012_30Apr2013S000009358_MemberInstitutionalShares_Member">Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (&amp;#8220;FDIC&amp;#8221;) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investment in the Fund involves substantial risks which prospective investors should consider carefully before investing.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Investment Style Risk.&lt;/b&gt;&amp;nbsp;&amp;nbsp;Different investment styles (e.g., &amp;#8220;growth,&amp;#8221; &amp;#8220;value&amp;#8221; or &amp;#8220;quantitative&amp;#8221;) tend to shift in and out of favor depending upon market and economic conditions and investor sentiment. The Fund may outperform or underperform other funds that invest in similar asset classes but employ different investment styles.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Market Risk.&lt;/b&gt;&amp;nbsp;&amp;nbsp;The value of the instruments in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Mid-Cap and Small-Cap Risk.&lt;/b&gt;&amp;nbsp;&amp;nbsp;Investments in mid-capitalization and small-capitalization companies involve greater risks than those associated with larger, more established companies. These securities may be subject to more abrupt or erratic price movements and may lack sufficient market liquidity, and these issuers often face greater business risks.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Stock Risk.&lt;/b&gt;&amp;nbsp;&amp;nbsp;Stock prices have historically risen and fallen in periodic cycles. U.S. and foreign stock markets have experienced periods of substantial price volatility in the past and may do so again in the future.</rr:RiskNarrativeTextBlock>

The Fund&amp;#8217;s past performance is not necessarily an indication of how the Fund will perform in the future. Performance reflects applicable fee waivers and/or expense limitations in effect during the periods shown. In addition, performance reflects Fund level expenses but does not reflect the fees and expenses associated with any variable annuity contract or variable life insurance policy that uses the Fund as an investment option for any contract or policy.

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01May2012_30Apr2013S000009362_MemberInstitutionalShares_Member">The Fund invests, under normal circumstances, at least 80% of its net assets plus any borrowings for investment purposes (measured at the time of purchase) (&amp;#8220;Net Assets&amp;#8221;) in high quality floating rate or variable rate obligations. The Fund considers &amp;#8220;high quality&amp;#8221; obligations to be (i) those rated AAA or Aaa by a nationally recognized statistical rating organization (&amp;#8220;NRSRO&amp;#8221;) at the time of purchase, or, if unrated, determined by the Investment Adviser to be of comparable quality, and (ii) securities issued or guaranteed by the U.S. Government, its agencies, instrumentalities or sponsored enterprises (&amp;#8220;U.S. Government Securities&amp;#8221;), including securities representing an interest in or collateralized by adjustable rate and fixed rate mortgage loans or other mortgage-related securities (&amp;#8220;Mortgage-Backed Securities&amp;#8221;), and in repurchase agreements collateralized by U.S. Government Securities. The remainder of the Fund&amp;#8217;s Net Assets (up to 20%) may be invested in fixed rate obligations (subject to the quality requirements specified above) or other investments. The Fund also intends to invest in derivatives, including (but not limited to) Eurodollar futures and interest rate swaps, which are used primarily to manage the Fund&amp;#8217;s duration. The Fund may invest in obligations of foreign issuers (including sovereign and agency obligations), although 100% of the Fund&amp;#8217;s portfolio will be invested in U.S. dollar denominated securities.&lt;br/&gt;&lt;br/&gt;The Fund&amp;#8217;s investments in floating and variable rate obligations may include, without limitation: agency floating rate bonds and agency Mortgage-Backed Securities, including adjustable rate mortgages and collateralized mortgage obligation floaters; asset-backed floating rate bonds including, but not limited to, those backed by Federal Family Education Loan Program (&amp;#8220;FFELP&amp;#8221;) student loans and credit card receivables; other floating rate Mortgage-Backed Securities; collateralized loan obligations; corporate obligations; and overnight repurchase agreements. &lt;br/&gt;&lt;br/&gt;The Fund&amp;#8217;s target duration range under normal interest rate conditions is that of the BofA ML Three Month U.S. Treasury Bill Index, plus or minus 1 year, and the duration of this index is typically approximately three months. &amp;#8220;Duration&amp;#8221; is a measure of a debt security&amp;#8217;s price sensitivity to changes in interest rates. The longer the duration of the Fund (or an individual debt security), the more sensitive its market price to changes in interest rates. For example, if market interest rates increase by 1%, the market price of a debt security with a positive duration of 3 will generally decrease by approximately 3%. Conversely, a 1% decline in market interest rates will generally result in an increase of approximately 3% of that security&amp;#8217;s market price.&lt;br/&gt;GSAM&amp;#8217;s Fixed Income Investing Philosophy:&lt;br/&gt;Global fixed income markets are constantly evolving and are highly diverse&amp;#8212;with myriad countries, currencies, sectors, issuers and securities. We believe that inefficiencies in these complex markets cause bond prices to diverge from their fair value. To capitalize on these inefficiencies and generate consistent risk-adjusted performance, we believe it is critical to:&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;Thoughtfully combine diversified sources of return by employing multiple strategies&lt;/li&gt;&lt;li style="margin-left:-20px"&gt;Take a global perspective to uncover relative value opportunities&lt;/li&gt;&lt;li style="margin-left:-20px"&gt;Employ focused specialist teams to identify short-term mis-pricings and incorporate long-term views&lt;/li&gt;&lt;li style="margin-left:-20px"&gt;Emphasize a risk-aware approach as we view risk management as both an offensive and defensive tool&lt;/li&gt;&lt;li style="margin-left:-20px"&gt;Build a strong team of skilled investors who excel on behalf of our clients&lt;/li&gt;&lt;/ul&gt;</rr:StrategyNarrativeTextBlock>

The Fund may also invest in custodial receipts, fixed income securities issued by or on behalf of states, territories, and possessions of the United States (including the District of Columbia) (&amp;#8220;Municipal Securities&amp;#8221;) and convertible securities. The Fund may also engage in forward foreign currency transactions for both speculative and hedging purposes.&lt;br/&gt;&lt;br/&gt;The Fund&amp;#8217;s investments in non-U.S. dollar denominated obligations (hedged or unhedged against currency risk) will not exceed 25% of its total assets (not including securities lending collateral and any investment of that collateral) measured at the time of purchase (&amp;#8220;Total Assets&amp;#8221;), and 10% of the Fund&amp;#8217;s Total Assets may be invested in obligations of issuers in countries with emerging markets or economies (&amp;#8220;emerging countries&amp;#8221;). Additionally, exposure to non-U.S. currencies (unhedged against currency risk) will not exceed 25% of the Fund&amp;#8217;s Total Assets. In pursuing its investment objective, the Fund uses the Index as its performance benchmark, but the Fund will not attempt to replicate the Index. The Fund may, therefore, invest in securities that are not included in the Index. &lt;br/&gt;&lt;br/&gt;The Fund may invest in fixed income securities rated at least BBB&amp;#8211; or Baa3 at the time of purchase.

The longer the duration of the Fund (or an individual debt security), the more sensitive its market price to changes in interest rates. For example, if market interest rates increase by 1%, the market price of a debt security with a positive duration of 3 will generally decrease by approximately 3%. Conversely, a 1% decline in market interest rates will generally result in an increase of approximately 3% of that security&amp;#8217;s market price.</rr:StrategyNarrativeTextBlock>

The remainder of the Fund&amp;#8217;s Net Assets (up to 20%) may be invested in fixed rate obligations (subject to the quality requirements specified above) or other investments. The Fund also intends to invest in derivatives, including (but not limited to) Eurodollar futures and interest rate swaps, which are used primarily to manage the Fund&amp;#8217;s duration.

  <rr:RiskNarrativeTextBlock contextRef="Duration_01May2012_30Apr2013S000009362_MemberServiceShares_Member">Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (&amp;#8220;FDIC&amp;#8221;) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investment in the Fund involves substantial risks which prospective investors should consider carefully before investing.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Credit/Default Risk.&lt;/b&gt;&amp;nbsp;&amp;nbsp;An issuer or guarantor of fixed income securities held by the Fund may default on its obligation to pay interest and repay principal or default on any other obligation. Additionally, the credit quality of securities may deteriorate rapidly, which may impair the Fund&amp;#8217;s liquidity and cause significant net asset value (&amp;#8220;NAV&amp;#8221;) deterioration.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Derivatives Risk.&lt;/b&gt;&amp;nbsp;&amp;nbsp;Loss may result from the Fund&amp;#8217;s investments in futures, swaps and other derivative instruments. These instruments may be illiquid, difficult to price and leveraged so that small changes may produce disproportionate losses to the Fund. Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligation.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Foreign Risk.&lt;/b&gt;&amp;nbsp;&amp;nbsp;Foreign securities may be subject to risk of loss because of more or less foreign government regulation, less public information and less economic, political and social stability in the countries in which the Fund invests. Loss may also result from the imposition of exchange controls, confiscations and other government restrictions, or from problems in registration, settlement or custody. In addition, the Fund will be subject to the risk that an issuer of non-U.S. sovereign debt or the governmental authorities that control the repayment of the debt may be unable or unwilling to repay the principal or interest when due.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Interest Rate Risk.&lt;/b&gt;&amp;nbsp;&amp;nbsp;When interest rates increase, fixed income securities or instruments held by the Fund will generally decline in value. Long-term fixed income securities or instruments will normally have more price volatility because of this risk than short-term fixed income securities or instruments.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Liquidity Risk.&lt;/b&gt;&amp;nbsp;&amp;nbsp;The Fund may make investments that are illiquid or that may become less liquid in response to market developments or adverse investor perceptions. Illiquid investments may be more difficult to value. Liquidity risk may also refer to the risk that the Fund will not be able to pay redemption proceeds within the allowable time period because of unusual market conditions, an unusually high volume of redemption requests or other reasons. To meet redemption requests, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Mortgage-Backed and Other Asset-Backed Risk.&lt;/b&gt;&amp;nbsp;&amp;nbsp;Mortgage-related and other asset-backed securities are subject to certain additional risks, including &amp;#8220;extension risk&amp;#8221; (i.e., in periods of rising interest rates, issuers may pay principal later than expected) and &amp;#8220;prepayment risk&amp;#8221; (i.e., in periods of declining interest rates, issuers may pay principal more quickly than expected, causing the Fund to reinvest proceeds at lower prevailing interest rates). Mortgage-backed securities offered by non-governmental issuers are subject to other risks as well, including failures of private insurers to meet their obligations and unexpectedly high rates of default on the mortgages backing the securities. Other asset-backed securities are subject to risks similar to those associated with mortgage-backed securities, as well as risks associated with the nature and servicing of the assets backing the securities. Asset-backed securities may not have the benefit of a security interest in collateral comparable to that of mortgage assets, resulting in additional credit risk.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;U.S. Government Securities Risk.&lt;/b&gt;&amp;nbsp;&amp;nbsp;The U.S. government may not provide financial support to U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law. U.S. Government Securities issued by the Federal National Mortgage Association (&amp;#8220;Fannie Mae&amp;#8221;), Federal Home Loan Mortgage Corporation (&amp;#8220;Freddie Mac&amp;#8221;) and the Federal Home Loan Banks are neither issued nor guaranteed by U.S. Treasury and, therefore, are not backed by the full faith and credit of the United States. The maximum potential liability of the issuers of some U.S. Government Securities held by the Fund may greatly exceed their current resources, including any legal right to support from the U.S. Treasury. It is possible that these issuers will not have the funds to meet their payment obligations in the future.</rr:RiskNarrativeTextBlock>

  <rr:RiskNarrativeTextBlock contextRef="Duration_01May2012_30Apr2013S000009353_MemberInstitutionalShares_Member">Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the (&amp;#8220;FDIC&amp;#8221;) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investment in the Fund involves substantial risks which prospective investors should consider carefully before investing.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Credit/Default Risk.&lt;/b&gt;&amp;nbsp;&amp;nbsp;An issuer or guarantor of fixed income securities or instruments held by the Fund may default on its obligation to pay interest and repay principal or default on any other obligation. Additionally, the credit quality of securities may deteriorate rapidly, which may impair the Fund&amp;#8217;s liquidity and cause significant net asset value (&amp;#8220;NAV&amp;#8221;) deterioration.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Derivatives Risk.&lt;/b&gt;&amp;nbsp;&amp;nbsp;Loss may result from the Fund&amp;#8217;s investments in forwards and other derivative instruments. These instruments may be illiquid, difficult to price and leveraged so that small changes may produce disproportionate losses to the Fund. Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligation.&lt;br/&gt;&lt;b&gt;Foreign and Emerging Countries Risk.&lt;/b&gt;&amp;nbsp;&amp;nbsp;Foreign securities may be subject to risk of loss because of more or less foreign government regulation, less public information and less economic, political and social stability in the countries in which the Fund invests. Loss may also result from the imposition of exchange controls, confiscations and other government restrictions, or from problems in share registration, settlement or custody. Foreign risk also involves the risk of negative foreign currency rate fluctuations, which may cause the value of securities denominated in such foreign currency (or other instruments through which the Fund has exposure to foreign currencies) to decline in value. Currency exchange rates may fluctuate significantly over short periods of time. To the extent that the Fund also invests in securities of issuers located in emerging markets, these risks may be more pronounced.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Interest Rate Risk.&lt;/b&gt;&amp;nbsp;&amp;nbsp;When interest rates increase, fixed income securities or instruments held by the Fund will generally decline in value. Long-term fixed income securities or instruments will normally have more price volatility because of this risk than short-term fixed income securities or instruments.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Mortgage-Backed and Other Asset-Backed Risk.&lt;/b&gt;&amp;nbsp;&amp;nbsp;Mortgage-related and other asset-backed securities are subject to certain additional risks, including &amp;#8220;extension risk&amp;#8221; (i.e., in periods of rising interest rates, issuers may pay principal later than expected) and &amp;#8220;prepayment risk&amp;#8221; (i.e., in periods of declining interest rates, issuers may pay principal more quickly than expected, causing the Fund to reinvest proceeds at lower prevailing interest rates). Mortgage-backed securities offered by non-governmental issuers are subject to other risks as well, including failures of private insurers to meet their obligations and unexpectedly high rates of default on the mortgages backing the securities. Other asset-backed securities are subject to risks similar to those associated with mortgage-backed securities, as well as risks associated with the nature and servicing of the assets backing the securities. Asset-backed securities may not have the benefit of a security interest in collateral comparable to that of mortgage assets, resulting in additional credit risk.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;U.S. Government Securities Risk.&lt;/b&gt;&amp;nbsp;&amp;nbsp;The U.S. government may not provide financial support to U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law. U.S. Government Securities issued by the Federal National Mortgage Association (&amp;#8220;Fannie Mae&amp;#8221;), Federal Home Loan Mortgage Corporation (&amp;#8220;Freddie Mac&amp;#8221;) and the Federal Home Loan Banks are neither issued nor guaranteed by the U.S. Treasury and, therefore, are not backed by the full faith and credit of the United States. The maximum potential liability of the issuers of some U.S. Government Securities held by the Fund may greatly exceed their current resources, including any legal right to support from the U.S. Treasury. It is possible that these issuers will not have the funds to meet their payment obligations in the future.</rr:RiskNarrativeTextBlock>

  <rr:RiskNarrativeTextBlock contextRef="Duration_01May2012_30Apr2013S000009362_MemberInstitutionalShares_Member">Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (&amp;#8220;FDIC&amp;#8221;) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investment in the Fund involves substantial risks which prospective investors should consider carefully before investing.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Credit/Default Risk.&lt;/b&gt;&amp;nbsp; An issuer or guarantor of fixed income securities held by the Fund may default on its obligation to pay interest and repay principal or default on any other obligation. Additionally, the credit quality of securities may deteriorate rapidly, which may impair the Fund&amp;#8217;s liquidity and cause significant net asset value (&amp;#8220;NAV&amp;#8221;) deterioration.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Derivatives Risk.&lt;/b&gt;&amp;nbsp; Loss may result from the Fund&amp;#8217;s investments in futures, swaps and other derivative instruments. These instruments may be illiquid, difficult to price and leveraged so that small changes may produce disproportionate losses to the Fund. Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligation.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Foreign Risk.&lt;/b&gt;&amp;nbsp; Foreign securities may be subject to risk of loss because of more or less foreign government regulation, less public information and less economic, political and social stability in the countries in which the Fund invests. Loss may also result from the imposition of exchange controls, confiscations and other government restrictions, or from problems in registration, settlement or custody. In addition, the Fund will be subject to the risk that an issuer of non-U.S. sovereign debt or the governmental authorities that control the repayment of the debt may be unable or unwilling to repay the principal or interest when due.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Interest Rate Risk.&lt;/b&gt;&amp;nbsp; When interest rates increase, fixed income securities or instruments held by the Fund will generally decline in value. Long-term fixed income securities or instruments will normally have more price volatility because of this risk than short-term fixed income securities or instruments.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Liquidity Risk.&lt;/b&gt;&amp;nbsp; The Fund may make investments that are illiquid or that may become less liquid in response to market developments or adverse investor perceptions. Illiquid investments may be more difficult to value. Liquidity risk may also refer to the risk that the Fund will not be able to pay redemption proceeds within the allowable time period because of unusual market conditions, an unusually high volume of redemption requests or other reasons. To meet redemption requests, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Mortgage-Backed and Other Asset-Backed Risk.&lt;/b&gt;&amp;nbsp; Mortgage-related and other asset-backed securities are subject to certain additional risks, including &amp;#8220;extension risk&amp;#8221; (i.e., in periods of rising interest rates, issuers may pay principal later than expected) and &amp;#8220;prepayment risk&amp;#8221; (i.e., in periods of declining interest rates, issuers may pay principal more quickly than expected, causing the Fund to reinvest proceeds at lower prevailing interest rates). Mortgage-backed securities offered by non-governmental issuers are subject to other risks as well, including failures of private insurers to meet their obligations and unexpectedly high rates of default on the mortgages backing the securities. Other asset-backed securities are subject to risks similar to those associated with mortgage-backed securities, as well as risks associated with the nature and servicing of the assets backing the securities. Asset-backed securities may not have the benefit of a security interest in collateral comparable to that of mortgage assets, resulting in additional credit risk.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;U.S. Government Securities Risk.&lt;/b&gt;&amp;nbsp; The U.S. government may not provide financial support to U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law. U.S. Government Securities issued by the Federal National Mortgage Association (&amp;#8220;Fannie Mae&amp;#8221;), Federal Home Loan Mortgage Corporation (&amp;#8220;Freddie Mac&amp;#8221;) and the Federal Home Loan Banks are neither issued nor guaranteed by the U.S. Treasury and, therefore, are not backed by the full faith and credit of the United States. The maximum potential liability of the issuers of some U.S. Government Securities held by the Fund may greatly exceed their current resources, including any legal right to support from the U.S. Treasury. It is possible that these issuers will not have the funds to meet their payment obligations in the future.</rr:RiskNarrativeTextBlock>

  <rr:RiskNarrativeTextBlock contextRef="Duration_01May2012_30Apr2013S000009359_MemberServiceShares_Member">Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (&amp;#8220;FDIC&amp;#8221;) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investment in the Fund involves substantial risks which prospective investors should consider carefully before investing.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Foreign and Emerging Countries Risk.&lt;/b&gt;&amp;nbsp;&amp;nbsp;Foreign securities may be subject to risk of loss because of more or less foreign government regulation, less public information and less economic, political and social stability in the countries in which the Fund invests. Loss may also result from the imposition of exchange controls, confiscations and other government restrictions, or from problems in share registration, settlement or custody. Foreign risk also involves the risk of negative foreign currency rate fluctuations, which may cause the value of securities denominated in such foreign currency (or other instruments through which the Fund has exposure to foreign currencies) to decline in value. Currency exchange rates may fluctuate significantly over short periods of time. To the extent the Fund also invests in issuers located in emerging countries, these risks may be more pronounced.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Market Risk.&lt;/b&gt;&amp;nbsp;&amp;nbsp;The value of the instruments in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Stock Risk.&lt;/b&gt;&amp;nbsp;&amp;nbsp;Stock prices have historically risen and fallen in periodic cycles. U.S. and foreign stock markets have experienced periods of substantial price volatility in the past and may do so again in the future.</rr:RiskNarrativeTextBlock>

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01May2012_30Apr2013S000009355_MemberServiceShares_Member">The Fund invests, under normal circumstances, at least 80% of its net assets plus any borrowings for investment purposes (measured at time of purchase) (&amp;#8220;Net Assets&amp;#8221;) in a broadly diversified portfolio of equity investments in small-cap U.S. issuers, including foreign issuers that are traded in the United States. These issuers will have public stock market capitalizations similar to that of the range of the market capitalizations of companies constituting the Russell 2000&lt;sup style="FONT-SIZE: 85%; VERTICAL-ALIGN: top"&gt;&amp;#174;&lt;/sup&gt; Index at the time of investment, which as of April 1, 2013 was between approximately $19 million and $5.77 billion. However, the Fund may invest in securities outside the Russell 2000&lt;sup style="FONT-SIZE: 85%; VERTICAL-ALIGN: top"&gt;&amp;#174;&lt;/sup&gt; Index capitalization range. &lt;br /&gt;&lt;br /&gt;The Fund uses a &amp;#8220;structured&amp;#8221; quantitative style of management, in combination with a qualitative overlay, that emphasizes fundamentally-based stock selection, careful portfolio construction and efficient implementation. The Fund&amp;#8217;s investments are selected using fundamental research and a variety of quantitative techniques based on certain investment themes, including, among others, Valuation, Quality and Momentum. The Valuation theme attempts to capture potential mispricings of securities, typically by comparing a measure of the company&amp;#8217;s intrinsic value to its market value. The Quality theme assesses both firm and management quality. The Momentum theme seeks to predict drifts in stock prices caused by delayed investor reaction to company-specific information and information about related companies. The Investment Adviser may, in its discretion, make changes to its quantitative techniques, or use other quantitative techniques that are based on the Investment Adviser&amp;#8217;s proprietary research. &lt;br /&gt;&lt;br /&gt;The Fund maintains risk, style, and capitalization characteristics similar to the Russell 2000&lt;sup style="FONT-SIZE: 85%; VERTICAL-ALIGN: top"&gt;&amp;#174;&lt;/sup&gt; Index, which is an index designed to represent an investable universe of small-cap companies. The Fund seeks to maximize expected return while maintaining these and other characteristics similar to the benchmark. &lt;br /&gt;&lt;br /&gt;The Investment Adviser will not consider the portfolio turnover rate a limiting factor in managing the Fund, and the Fund&amp;#8217;s investment style may result in frequent trading and relatively high portfolio turnover. &lt;br /&gt;&lt;br /&gt;The Fund may also invest in fixed income securities that are considered to be cash equivalents.</rr:StrategyNarrativeTextBlock>

  <rr:RiskNarrativeTextBlock contextRef="Duration_01May2012_30Apr2013S000009355_MemberServiceShares_Member">Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (&amp;#8220;FDIC&amp;#8221;) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investment in the Fund involves substantial risks which prospective investors should consider carefully before investing.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Investment Style Risk.&lt;/b&gt;&amp;nbsp;&amp;nbsp;Different investment styles (e.g., &amp;#8220;growth,&amp;#8221; &amp;#8220;value&amp;#8221; or &amp;#8220;quantitative&amp;#8221;) tend to shift in and out of favor depending upon market and economic conditions and investor sentiment. The Fund employs a &amp;#8220;quantitative&amp;#8221; style, and may outperform or underperform other funds that invest in similar asset classes but employ different investment styles.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Management Risk.&lt;/b&gt;&amp;nbsp;&amp;nbsp;A strategy used by the Investment Adviser may fail to produce the intended results. The Investment Adviser attempts to execute a complex strategy for the Fund using proprietary quantitative models. Investments selected using these models may perform differently than expected as a result of the factors used in the models, the weight placed on each factor, changes from the factors&amp;#8217; historical trends, and technical issues in the construction and implementation of the models (including, for example, data problems and/or software issues).

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01May2012_30Apr2013S000009352_MemberServiceShares_Member">The Fund invests, under normal circumstances, at least 80% of its net assets plus any borrowings for investment purposes (measured at time of purchase) (&amp;#8220;Net Assets&amp;#8221;) in a diversified portfolio of equity investments in U.S. issuers, including foreign companies that are traded in the United States. &lt;br /&gt;&lt;br /&gt;The Fund uses a &amp;#8220;structured&amp;#8221; quantitative style of management, in combination with a qualitative overlay, that emphasizes fundamentally-based stock selection, careful portfolio construction and efficient implementation. The Fund&amp;#8217;s investments are selected using fundamental research and a variety of quantitative techniques based on certain investment themes, including, among others, Valuation, Quality and Momentum. The Valuation theme attempts to capture potential mispricings of securities, typically by comparing a measure of the company&amp;#8217;s intrinsic value to its market value. The Quality theme assesses both firm and financial quality. The Momentum theme seeks to predict drifts in stock prices caused by delayed investor reaction to company-specific information and information about related companies. The Investment Adviser may, in its discretion, make changes to its quantitative techniques, or use other quantitative techniques that are based on the Investment Adviser&amp;#8217;s proprietary research. &lt;br /&gt;&lt;br /&gt;The Fund maintains risk, style, and capitalization characteristics similar to the Standard &amp;amp; Poor&amp;#8217;s 500&lt;sup style="FONT-SIZE: 85%; VERTICAL-ALIGN: top"&gt;&amp;#174;&lt;/sup&gt; Index (the &amp;#8220;S&amp;amp;P 500&lt;sup style="FONT-SIZE: 85%; VERTICAL-ALIGN: top"&gt;&amp;#174;&lt;/sup&gt; Index&amp;#8221;), which is an index of large-cap stocks designed to reflect a broad representation of the U.S. economy. As of April 1, 2013, the market capitalization range for the S&amp;amp;P 500&lt;sup style="FONT-SIZE: 85%; VERTICAL-ALIGN: top"&gt;&amp;#174;&lt;/sup&gt; Index was between approximately $1.74 billion and $406.69 billion. The Fund seeks to maximize expected return while maintaining these and other characteristics similar to the benchmark. However, the Fund may invest in securities outside the S&amp;amp;P 500&lt;sup style="FONT-SIZE: 85%; VERTICAL-ALIGN: top"&gt;&amp;#174;&lt;/sup&gt; capitalization range. &lt;br /&gt;&lt;br /&gt;The Investment Adviser will not consider the portfolio turnover rate a limiting factor in managing the Fund, and the Fund&amp;#8217;s investment style may result in frequent trading and relatively high portfolio turnover. &lt;br /&gt;&lt;br /&gt;The Fund may also invest in fixed income securities that are considered to be cash equivalents.</rr:StrategyNarrativeTextBlock>
