  <rr:PortfolioTurnoverTextBlock contextRef="Duration_01May2014_30Apr2015S000009362_MemberAdvisor_Member">The Fund pays transaction costs when it buys and sells securities or instruments (i.e., &amp;#8220;turns over&amp;#8221; its portfolio). A high rate of portfolio turnover may result in increased transaction costs, which must be borne by the Fund and its shareholders. These costs are not reflected in annual fund operating expenses or in the expense example above, but are reflected in the Fund&amp;#8217;s performance. The Fund&amp;#8217;s portfolio turnover rate for the fiscal year ended December 31, 2014 was 17% of the average value of its portfolio.</rr:PortfolioTurnoverTextBlock>
  <rr:StrategyNarrativeTextBlock contextRef="Duration_01May2014_30Apr2015S000009362_MemberAdvisor_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. Floating rate and variable rate obligations are debt instruments issued by companies or other entities with interest rates that reset periodically (typically, daily, monthly, quarterly, or semi-annually) in response to changes in the market rate of interest on which the interest rate is based. 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 credit quality, including repurchase agreements with counterparties rated AAA or Aaa by an NRSRO at the time of purchase, or, if unrated, determined by the Investment Adviser to be of comparable credit 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, with counterparties approved by the Investment Adviser pursuant to procedures approved by the Board of Trustees. The remainder of the Fund&amp;#8217;s Net Assets (up to 20%) may include, but are not limited to, fixed rate obligations (subject to the credit quality requirements specified above). 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 obligations issued by foreign governments and their agencies, instrumentalities or sponsored enterprises), 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 expected to approximate that of the Bank of America Merrill Lynch 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;&lt;br /&gt;The Fund&amp;#8217;s benchmark index is the Bank of America Merrill Lynch Three-Month U.S. Treasury Bill Index.&lt;br /&gt;&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 a large number of 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>

  <rr:RiskNarrativeTextBlock contextRef="Duration_01May2014_30Apr2015S000009362_MemberAdvisor_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. Investments in the Fund involve 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 deterioration in net asset value (&amp;#8220;NAV&amp;#8221;).&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 options, futures, swaps and other derivative instruments. These instruments may be illiquid, difficult to price and leveraged so that small changes in the value of underlying instruments 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, sanctions, confiscations and other government restrictions by the United States and other governments, 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;Large Shareholder Transactions Risk.&lt;/b&gt;&amp;nbsp; The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund&amp;#8217;s NAV and liquidity. Similarly, large Fund share purchases may adversely affect the Fund&amp;#8217;s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also increase transaction costs. In addition, a large redemption could result in the Fund&amp;#8217;s current expenses being allocated over a smaller asset base, leading to an increase in the Fund&amp;#8217;s expense ratio.&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. Liquidity risk may be the result of, among other things, the reduced number and capacity of traditional market participants to make a market in fixed income securities or the lack of an active market. The potential for liquidity risk may be magnified by a rising interest rate environment or other circumstances where investor redemptions from fixed income mutual funds may be higher than normal, potentially causing increased supply in the market due to selling activity.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Mortgage-Backed and Other Asset-Backed Securities 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 their 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>

(&amp;#8220;GSAM&amp;#8221; or the &amp;#8220;Investment Adviser&amp;#8221;) or an affiliate now or in the future acts as investment adviser or principal underwriter (the &amp;#8220;Underlying Funds&amp;#8221;). The Portfolio invests in Underlying Funds that pursue a variety of strategies and invest in a variety of asset classes. The Investment Adviser selects strategies and asset classes based on the desired risk profile and investment objective for the Portfolio. The Portfolio invests primarily in a portfolio of Underlying Funds that provide exposure to Liquid Alternatives Strategies and Real Assets (&amp;#8220;Underlying Asset Classes and Strategies&amp;#8221;). Liquid Alternatives Strategies generally include, but are not limited to, momentum or trend trading strategies (investment decisions based on trends in asset prices over time), hedge fund beta (long term total returns consistent with investment results that approximate the return and risk patterns of a diversified universe of hedge funds), managed risk investment strategies (which seek to manage extreme risk scenarios by implementing daily and monthly risk targets across a diversified mix of asset classes), emerging markets debt and unconstrained fixed income strategies (which have the ability to move across various fixed income sectors). Real Assets generally include, but are not limited to, commodities, global real estate securities, infrastructure and master limited partnerships (&amp;#8220;MLPs&amp;#8221;).&lt;br /&gt;&lt;br /&gt;Through its investments in Underlying Funds and/or unaffiliated exchange-traded funds (&amp;#8220;ETFs&amp;#8221;), the Portfolio may indirectly invest in the following to obtain exposure to Underlying Asset Classes and Strategies: (i) equity securities, including common and preferred stocks, real estate investment trusts (&amp;#8220;REITs&amp;#8221;), pooled investment vehicles (including other unaffiliated investment companies and ETFs) and partnership interests, including MLPs; (ii) fixed income and/or floating rate securities, including debt issued by corporations, debt issued by governments (including the U.S. and foreign governments), their agencies, instrumentalities, sponsored entities, and political subdivisions, covered bonds, notes, debentures, debt participations, convertible bonds, non-investment grade securities (commonly known as &amp;#8220;junk bonds&amp;#8221;), bank loans and other direct indebtedness; (iii) mortgage-backed and other mortgage-related securities, asset-backed securities, municipal securities, to be announced (&amp;#8220;TBA&amp;#8221;) securities and custodial receipts; (iv) currencies; and (v) restricted securities eligible for resale pursuant to Rule 144A under the Securities Act of 1933 (&amp;#8220;144A Securities&amp;#8221;). These investments may be publicly traded or privately issued or negotiated. The Portfolio may also invest directly in all of the above instruments. The Portfolio may invest without restriction as to issuer capitalization, country, currency, maturity or credit rating.&lt;br /&gt;&lt;br /&gt;The Portfolio and certain Underlying Funds may also invest in derivatives for both hedging and investment purposes. The Portfolio&amp;#8217;s derivative exposure (which will primarily be obtained through its investments in the Underlying Funds) may include (i) futures contracts, including futures based on equity or fixed income securities and/or equity or fixed income indices, interest rate futures, currency futures and swap futures; (ii) swaps, including equity, currency, interest rate, total return, variance and credit default swaps and swaps on futures contracts; (iii) options, including long and short positions in call options and put options on indices, individual securities or currencies, swaptions and options on futures contracts; (iv) forward contracts, including forwards based on equity or fixed income securities and/or equity or fixed income indices, currency forwards, interest rate forwards, swap forwards and non-deliverable forwards; and (v) other instruments, including structured securities, credit linked notes, exchange-traded notes and contracts for differences (&amp;#8220;CFDs&amp;#8221;). The Portfolio&amp;#8217;s direct derivatives investments are expected to consist primarily of futures, options on indices and currency forwards, which the Portfolio may use to gain exposure to certain markets or currencies.&lt;br /&gt;&lt;br /&gt;The Portfolio intends to invest no more than 20% of its total assets in Underlying Funds that are managed by an investment advisor other than GSAM or its affiliates. In managing the Portfolio, the Investment Adviser seeks to budget or allocate portfolio risk, as opposed to capital. The Investment Adviser adjusts the Portfolio&amp;#8217;s risk exposures based on changes to its macro-economic views, changes to absolute and relative valuations across the Portfolio&amp;#8217;s exposures, and changes in the risk characteristics of the Portfolio&amp;#8217;s investments over time. The Investment Adviser may make short- to medium-term allocation adjustments to each Underlying Asset Class and Strategy and their constituents based on reasoned views of short- to medium-term market conditions with the goal of improving the Portfolio&amp;#8217;s investments over time. The Investment Adviser may change the Portfolio&amp;#8217;s allocation ranges, Underlying Asset Classes and Strategies and underlying investments from time to time at its discretion to incorporate its market views into the investment process and to react to changes in the macro-economic environment.

  <rr:RiskNarrativeTextBlock contextRef="Duration_01May2014_30Apr2015S000044541_MemberAdvisor_Member">&lt;b&gt;Loss of money is a risk of investing in the Portfolio. The investment program of the Portfolio is speculative, entails substantial risks and includes alternative investment techniques not employed by traditional mutual funds. The Portfolio should not be relied upon as a complete investment program. The Portfolio investment techniques (if they do not perform as designed) may increase the volatility of performance and the risk of investment loss, including the loss of the entire amount that is invested, and there can be no assurance that the investment objective of the Portfolio will be achieved. Moreover, certain investment techniques which the Portfolio may employ in its investment program can substantially increase the adverse impact to which the Portfolio investments may be subject. There is no assurance that the investment processes of the Portfolio will be successful, that the techniques utilized therein will be implemented successfully or that they are adequate for their intended uses, or that the discretionary element of the investment processes of the Portfolio will be exercised in a manner that is successful or that is not adverse to the Portfolio. An investment in the Portfolio 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. Investors should carefully consider these risks before investing. &lt;/b&gt;&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Derivatives Risk&lt;/b&gt;.&amp;nbsp; Loss may result from the Portfolio&amp;#8217;s investments in futures, options on indices, currency forwards and other derivative instruments. These instruments may be illiquid, difficult to price and leveraged so that small changes in the value of the underlying instruments may produce disproportionate losses to the Portfolio. Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligations.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Expenses&lt;/b&gt;.&amp;nbsp; By investing in the Underlying Funds and unaffiliated ETFs indirectly through the Portfolio, the investor will incur not only a proportionate share of the expenses of the Underlying Funds and unaffiliated ETFs held by the Portfolio (including operating costs and investment management fees), but also expenses of the Portfolio.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Investing in the Underlying Funds and Unaffiliated ETFs&lt;/b&gt;.&amp;nbsp; The investments of the Portfolio are concentrated in the Underlying Funds, and the Portfolio&amp;#8217;s investment performance is directly related to the investment performance of the Underlying Funds and unaffiliated ETFs it holds. The ability of the Portfolio to meet its investment objective is directly related to the ability of the Underlying Funds and unaffiliated ETFs to meet their objectives, as well as the allocation among those Underlying Funds and unaffiliated ETFs by the Investment Adviser.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Investments in Affiliated Underlying Funds&lt;/b&gt;.&amp;nbsp; The Investment Adviser will have the authority to select and substitute Underlying Funds. The Investment Adviser and/or its affiliates are compensated by the Portfolio and by the Underlying Funds for advisory and/or principal underwriting services provided. The Investment Adviser is subject to conflicts of interest in allocating Portfolio assets among the various Underlying Funds both because the fees payable to it and/or its affiliates by Underlying Funds differ and because the Investment Adviser and its affiliates are also responsible for managing the Underlying Funds. The portfolio managers may also be subject to conflicts of interest in allocating Portfolio assets among the various Underlying Funds because the Portfolio&amp;#8217;s portfolio management team may also manage some of the Underlying Funds. The Trustees and officers of the Goldman Sachs Trust may also have conflicting interests in fulfilling their fiduciary duties to both the Portfolio and the Underlying Funds for which GSAM or its affiliates now or in the future serve as investment adviser or principal underwriter. In selecting actively managed Underlying Funds, the Investment Adviser generally expects to select affiliated investment companies without considering or canvassing the universe of unaffiliated investment companies available even though there may (or may not) be one or more unaffiliated investment company that may be a more appropriate addition to the Portfolio. To the extent that an investment in an affiliated investment company is not available, including as the result of capacity constraints, only then will the Investment Adviser consider unaffiliated investment companies.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Investments of the Underlying Funds&lt;/b&gt;.&amp;nbsp; Because the Portfolio invests in the Underlying Funds and unaffiliated ETFs, the Portfolio&amp;#8217;s shareholders will be affected by the investment policies and practices of the Underlying Funds and unaffiliated ETFs in direct proportion to the amount of assets the Portfolio allocates to those Underlying Funds and unaffiliated ETFs. See the Principal Risks of the Underlying Funds below.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Large Shareholder Transactions Risk&lt;/b&gt;.&amp;nbsp; The Portfolio may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Portfolio. Such large shareholder redemptions may cause the Portfolio to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Portfolio&amp;#8217;s NAV and liquidity. Similarly, large Portfolio share purchases may adversely affect the Portfolio&amp;#8217;s performance to the extent that the Portfolio is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also increase transaction costs. In addition, a large redemption could result in the Portfolio&amp;#8217;s current expenses being allocated over a smaller asset base, leading to an increase in the Portfolio&amp;#8217;s expense ratio.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Temporary Investments&lt;/b&gt;.&amp;nbsp; Although the Portfolio normally seeks to invest primarily in the Underlying Funds, the Portfolio may invest a portion of its assets in high-quality, short-term debt obligations to maintain liquidity, to meet shareholder redemptions and for other short-term cash needs. For temporary defensive purposes during abnormal market or economic conditions, the Portfolio may invest without limitation in short-term obligations. When the Portfolio&amp;#8217;s assets are invested in such investments, the Portfolio may not be achieving its investment objective.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Principal Risks of the Underlying Funds &lt;/b&gt;&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Absence of Regulation&lt;/b&gt;.&amp;nbsp; Certain Underlying Funds engage 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;Call/Prepayment Risk&lt;/b&gt;.&amp;nbsp;   An issuer could exercise its right to pay principal on an obligation held by an Underlying Fund (such as a mortgage-backed security) earlier than expected. This may happen when there is a decline in interest rates, when credit spreads change, or when an issuer&amp;#8217;s credit quality improves. Under these circumstances, the Underlying Fund may be unable to recoup all of its initial investment and will also suffer from having to reinvest in lower yielding securities.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Commodity Sector Risk&lt;/b&gt;.&amp;nbsp;   Exposure to the commodities markets may subject an Underlying Fund to greater volatility than investments in more traditional securities. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. The prices of energy, industrial metals, precious metals, agriculture and livestock sector commodities may fluctuate widely due to factors such as changes in value, supply and demand and governmental regulatory policies. The commodity-linked investments in which an Underlying Fund&amp;#8217;s subsidiary may enter into may involve counterparties in the financial services sector, and events affecting the financial services sector may cause the subsidiary&amp;#8217;s, and therefore the Underlying Fund&amp;#8217;s, share value to fluctuate.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Counterparty Risk&lt;/b&gt;.&amp;nbsp;   Many of the protections afforded to participants on some organized exchanges, such as the security afforded by transacting through a clearinghouse, might not be available in connection with OTC transactions. Therefore, in those instances in which an Underlying Fund enters into OTC transactions, the Underlying Fund will be subject to the risk that its direct counterparty will not perform its obligations under the transactions and that the Underlying Fund will sustain losses.&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 an Underlying 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 an Underlying Fund&amp;#8217;s liquidity and cause significant net asset value (&amp;#8220;NAV&amp;#8221;) deterioration. To the extent that an Underlying Fund invests in non-investment grade fixed income securities, these risks may be more pronounced.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Derivatives Risk&lt;/b&gt;.&amp;nbsp; Loss may result from an Underlying Fund&amp;#8217;s investments in options, futures, forwards, swaps, structured securities and other derivative instruments. These instruments may be illiquid, difficult to price and leveraged so that small changes in the value of the underlying instruments may produce disproportionate losses to an Underlying 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;Distressed Debt Risk&lt;/b&gt;.&amp;nbsp;   When an Underlying Fund invests in obligations of financially troubled companies (sometimes known as &amp;#8220;distressed&amp;#8221; securities), there exists the risk that the transaction involving such debt obligations will be unsuccessful, take considerable time or will result in a distribution of cash or a new security or obligation in exchange for the stressed and distressed debt obligations, the value of which may be less than the Underlying Fund&amp;#8217;s purchase price of such debt obligations. Furthermore, if an anticipated transaction does not occur, the Underlying Fund may be required to sell its investment at a loss or hold its investment pending bankruptcy proceedings in the event the issuer files for bankruptcy.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Floating and Variable Rate Obligations Risks&lt;/b&gt;.&amp;nbsp; For floating and variable rate obligations, there may be a lag between an actual change in the underlying interest rate benchmark and the reset time for an interest payment of such an obligation, which could harm or benefit an Underlying Fund, depending on the interest rate environment or other circumstances. In a rising interest rate environment, for example, a floating or variable rate obligation that does not reset immediately would prevent an Underlying Fund from taking full advantage of rising interest rates in a timely manner. However, in a declining interest rate environment, an Underlying Fund may benefit from a lag due to an obligation&amp;#8217;s interest rate payment not being immediately impacted by a decline in interest rates.&lt;br /&gt;&lt;br /&gt;Certain floating and variable rate obligations have an interest rate floor feature, which prevents the interest rate payable by the security from dropping below a specified level as compared to a reference interest rate (the &amp;#8220;reference rate&amp;#8221;), such as LIBOR. Such a floor protects an Underlying Fund from losses resulting from a decrease in the reference rate below the specified level. However, if the reference rate is below the floor, there will be a lag between a rise in the reference rate and a rise in the interest rate payable by the obligation, and an Underlying Fund may not benefit from increasing interest rates for a significant amount of time.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Foreign and Emerging Countries 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, less liquidity, greater volatility and less economic, political and social stability in the countries in which an Underlying Fund invests. Loss may also result from the imposition of exchange controls, sanctions, foreign taxes, confiscations, expropriations and other government restrictions by the United States and other governments, 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 an Underlying 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 an Underlying 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;Industry Concentration Risk&lt;/b&gt;.&amp;nbsp;   The Goldman Sachs International Real Estate Securities Fund (&amp;#8220;Underlying International Real Estate Securities Fund&amp;#8221;) and Goldman Sachs Real Estate Securities Fund (&amp;#8220;Underlying Real Estate Securities Fund&amp;#8221;) concentrate their investments in the real estate industry, which has historically experienced substantial price volatility. This concentration subjects the Underlying International Real Estate Securities and Underlying Real Estate Securities Funds to greater risk of loss as a result of adverse economic, business or other developments than if their investments were diversified across different industries.&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 an Underlying 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;Investment Style Risk&lt;/b&gt;.&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. An Underlying 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;Large Shareholder Transactions Risk&lt;/b&gt;.&amp;nbsp;&amp;nbsp; An Underlying Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Underlying Fund. Such large shareholder redemptions may cause an Underlying Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Underlying Fund&amp;#8217;s NAV and liquidity. Similarly, large Underlying Fund share purchases may adversely affect the Underlying Fund&amp;#8217;s performance to the extent that the Underlying Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also increase transaction costs. In addition, a large redemption could result in the Underlying Fund&amp;#8217;s current expenses being allocated over a smaller asset base, leading to an increase in the Underlying Fund&amp;#8217;s expense ratio.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Leverage Risk&lt;/b&gt;.&amp;nbsp;   Borrowing and the use of derivatives may result in leverage and may make an Underlying Fund more volatile. Borrowing and the use of leverage may cause an Underlying 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 an Underlying Fund can substantially increase the adverse impact to which the Underlying 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; An Underlying 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 an Underlying 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, an Underlying Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions. Liquidity risk may be the result of, among other things, the reduced number and capacity of traditional market participants to make a market in fixed income securities or the lack of an active market. The potential for liquidity risk may be magnified by a rising interest rate environment or other circumstances where investor redemptions from fixed income mutual funds may be higher than normal, potentially causing increased supply in the market due to selling activity.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Loan-Related Investments Risk&lt;/b&gt;.&amp;nbsp; In addition to risks generally associated with debt investments, loan-related investments such as loan participations and assignments are subject to other risks. Although a loan obligation may be fully collateralized at the time of acquisition, the collateral may decline in value, be relatively illiquid, or lose all or substantially all of its value subsequent to investment. Many loan investments are subject to legal or contractual restrictions on resale and may be relatively illiquid and difficult to value. There is less readily available, reliable information about most loan investments than is the case for many other types of securities. Substantial increases in interest rates may cause an increase in loan obligation defaults. With respect to loan participations, an Underlying Fund may not always have direct recourse against a borrower if the borrower fails to pay scheduled principal and/or interest; may be subject to greater delays, expenses and risks than if the Underlying Fund had purchased a direct obligation of the borrower; and may be regarded as the creditor of the agent lender (rather than the borrower), subjecting the Underlying Fund to the creditworthiness of that lender as well. The market for loan obligations may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods. Because transactions in many loans are subject to extended trade settlement periods, the Underlying Fund may not receive the proceeds from the sale of a loan for a period after the sale. As a result, sale proceeds related to the sale of loans may not be available to make additional investments or to meet the Underlying Fund&amp;#8217;s redemption obligations for a period after the sale of the loans, and, as a result, the Underlying Fund may have to sell other investments or engage in borrowing transactions, such as borrowing from its credit facility, if necessary to raise cash to meet its obligations.&lt;br /&gt;&lt;br /&gt;Senior loans hold the most senior position in the capital structure of a business entity, and are typically secured with specific collateral, but are nevertheless usually rated below investment grade. Because second lien loans are subordinated or unsecured and thus lower in priority of payment to senior loans, they are subject to the additional risk that the cash flow of the borrower and property securing the loan or debt, if any, may be insufficient to meet scheduled payments after giving effect to the senior secured obligations of the borrower. Second lien loans generally have greater price volatility than senior loans and may be less liquid.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Management Risk&lt;/b&gt;.&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 with respect to certain of the Underlying Funds 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). There is no guarantee that the Investment Adviser&amp;#8217;s use of these quantitative models will result in effective investment decisions for an Underlying Fund. Additionally, commonality of holdings across quantitative money managers may amplify losses.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Market Risk&lt;/b&gt;.&amp;nbsp; The market value of the securities in which an Underlying 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; 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;Mortgage-Backed and Other Asset-Backed Securities 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 an Underlying 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;Municipal Securities Risk&lt;/b&gt;.&amp;nbsp; Municipal securities are subject to call/prepayment risk, credit/default risk, interest rate risk and certain additional risks. An Underlying Fund may be more sensitive to adverse economic, business or political developments if it invests a substantial portion of its assets in the bonds of similar projects (such as those relating to education, health care, housing, transportation, and utilities), industrial development bonds, or in particular types of municipal securities (such as general obligation bonds, private activity bonds and moral obligation bonds).&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Non-Diversification Risk&lt;/b&gt;.&amp;nbsp; Certain of the Underlying Funds are non-diversified, meaning that they are permitted to invest a larger percentage of their assets in fewer issuers than diversified mutual funds. Thus, an Underlying 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;Non-Hedging Foreign Currency Trading Risk&lt;/b&gt;.&amp;nbsp;   Certain Underlying Funds may engage in forward foreign currency transactions for investment purposes. An Underlying Fund&amp;#8217;s investment adviser may purchase or sell foreign currencies through the use of forward contracts based on the investment adviser&amp;#8217;s judgment regarding the direction of the market for a particular foreign currency or currencies. In pursuing this strategy, the Underlying Fund&amp;#8217;s investment adviser seeks to profit from anticipated movements in currency rates by establishing &amp;#8220;long&amp;#8221; and/or &amp;#8220;short&amp;#8221; positions in forward contracts on various foreign currencies. Foreign exchange rates can be extremely volatile and a variance in the degree of volatility of the market or in the direction of the market from the investment adviser&amp;#8217;s expectations may produce significant losses to the Underlying Fund. Some of these transactions may also be subject to interest rate risk.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Non-Investment Grade Fixed Income Securities Risk&lt;/b&gt;.&amp;nbsp; Non-investment grade fixed income securities and unrated securities of comparable credit quality (commonly known as &amp;#8220;junk bonds&amp;#8221;) are considered speculative and are subject to the increased risk of an issuer&amp;#8217;s inability to meet principal and interest payment obligations. These securities may be subject to greater price volatility due to such factors as specific issuer developments, interest rate sensitivity, negative perceptions of the junk bond markets generally and less liquidity.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Portfolio Turnover Rate Risk&lt;/b&gt;.&amp;nbsp; A high rate of portfolio turnover (100% or more) involves correspondingly greater expenses which must be borne by an Underlying Fund and its shareholders (including the Portfolio), and is also likely to result in short-term capital gains taxable to shareholders of the Underlying Fund.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Real Estate Industry Risk&lt;/b&gt;.&amp;nbsp;   Risks associated with investments in the real estate industry include, among others: possible declines in the value of real estate; risks related to general and local economic conditions; possible lack of availability of mortgage financing, variations in rental income, neighborhood values or the appeal of property to tenants; interest rates; overbuilding; extended vacancies of properties; increases in competition, property taxes and operating expenses; and changes in zoning laws. The real estate industry is particularly sensitive to economic downturns. The values of securities of companies in the real estate industry may go through cycles of relative underperformance and out-performance in comparison to equity securities markets in general.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;REIT Risk&lt;/b&gt;.&amp;nbsp;   REITs whose underlying properties are concentrated in a particular industry or geographic region are subject to risks affecting such industries and regions. The securities of REITs involve greater risks than those associated with larger, more established companies and may be subject to more abrupt or erratic price movements because of interest rate changes, economic conditions and other factors. Securities of such issuers may lack sufficient market liquidity to enable an Underlying Fund to effect sales at an advantageous time or without a substantial drop in price.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Short Position Risk&lt;/b&gt;.&amp;nbsp;   An Underlying Fund may enter into a short position through a futures contract, an option or swap agreement or through short sales of any instrument that the Underlying Fund may purchase for investment. Taking short positions involves leverage of the Underlying Fund&amp;#8217;s assets and presents various risks. If the value of the underlying instrument or market in which the Underlying Fund has taken a short position increases, then the Underlying Fund will incur a loss equal to the increase in value from the time that the short position was entered into plus any related interest payments or other fees. Taking short positions involves the risk that losses may be disproportionate, may exceed the amount invested and may be unlimited.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Sovereign Default Risk&lt;/b&gt;.&amp;nbsp; 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. 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;Special Situation Investments Risk&lt;/b&gt;.&amp;nbsp;   An Underlying Fund may make investments in event-driven situations such as recapitalizations, financings, corporate and financial restructurings, acquisitions, divestitures, reorganizations or other situations in public or private companies that may provide the Underlying Fund with an opportunity to provide debt and/or equity financing, typically on a negotiated basis. The Investment Adviser of the Underlying Fund will seek special situation investment opportunities with limited downside risk relative to their potential upside. These investments are complicated and an incorrect assessment of the downside risk associated with an investment could result in significant losses to the Underlying Fund.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Stock Risk&lt;/b&gt;.&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.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Subsidiary Risk&lt;/b&gt;.&amp;nbsp;   The subsidiaries of certain Underlying Funds are not registered under the Investment Company Act of 1940, as amended (&amp;#8220;Investment Company Act&amp;#8221;) and are not subject to all the investor protections of the Investment Company Act. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of an Underlying Fund and/or its subsidiary to operate as intended and could adversely affect the Underlying Fund.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Swaps Risk&lt;/b&gt;.&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 an Underlying 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;Tax Risk&lt;/b&gt;.&amp;nbsp;   Certain Underlying Funds will seek to gain exposure to the commodity markets primarily through investments in a subsidiary and/or commodity index-linked structured notes. Historically, the Internal Revenue Service (&amp;#8220;IRS&amp;#8221;) has issued private letter rulings in which the IRS specifically concluded that income and gains from investments in commodity index-linked structured notes or a wholly-owned foreign subsidiary that invests in commodity-linked instruments are &amp;#8220;qualifying income&amp;#8221; for purposes of compliance with Subchapter M of the Internal Revenue Code of 1986, as amended (the &amp;#8220;Code&amp;#8221;). However, while certain Underlying Funds have received such a private letter ruling, others have not, and those that have not are unable to rely on private letter rulings issued to other taxpayers. Additionally, the IRS has suspended the granting of such private letter rulings, pending review of its position on this matter. The tax treatment of certain Underlying Funds&amp;#8217; investments in a subsidiary or commodity index-linked structured notes may be adversely affected by future legislation, Treasury Regulations and/or guidance issued by the IRS (which may be retroactive) that could affect whether income derived from such investments is &amp;#8220;qualifying income&amp;#8221; under Subchapter M of Code, or otherwise affect the character, timing and/or amount of the Underlying Funds&amp;#8217; taxable income or any gains and distributions made by the Underlying Funds. In connection with investments in a subsidiary and/or commodity index-linked structured notes, certain Underlying Funds have obtained or may seek to obtain an opinion of counsel that their income from such investments should constitute &amp;#8220;qualifying income.&amp;#8221; However, no assurances can be provided that the IRS would not be able to successfully assert that the Underlying Funds&amp;#8217; income from such investments was not &amp;#8220;qualifying income&amp;#8221;, in which case an Underlying Fund would fail to qualify as a regulated investment company (RIC) under Subchapter M of the Code if over 10% of its gross income was derived from these investments. If an Underlying Fund failed to qualify as a RIC, it would be subject to federal and state income tax on all of its taxable income at regular corporate tax rates with no deduction for any distributions paid to shareholders, which would significantly adversely affect the returns to, and could cause substantial losses for, Underlying Fund shareholders.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Treasury Inflation Protected Securities Risk&lt;/b&gt;.&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; 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 those agencies, instrumentalities and sponsored enterprises, including those 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 an Underlying 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.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Further Information on Investment Objectives, Strategies and Risks of the Underlying Funds.&lt;/b&gt;&amp;nbsp; A concise description of the investment objectives, practices and risks of each of the Underlying Funds that are currently expected to be used for investment by the Portfolio as of the date of this Prospectus is provided beginning on page 14 of this Prospectus.</rr:RiskNarrativeTextBlock>

  <rr:RiskNarrativeTextBlock contextRef="Duration_01May2014_30Apr2015S000043924_MemberAdvisor_Member">Loss of money is a risk of investing in the Fund. The Investment Adviser will not manage the investment program of the Fund by reference to a benchmark index (i.e., unconstrained). By removing benchmark constraints, the Fund is able to invest across the global fixed income spectrum without regard to sector, quality, maturity or market capitalization limitations, including in asset classes in which more traditional or benchmark-constrained fixed income funds do not typically invest (or do not invest to such an extent). Due to this flexible strategy, the Fund's risk exposure may vary, and the Fund may underperform traditional fixed income indices. There can be no assurance that the discretionary element of the investment processes of the Investment Adviser will be exercised in a manner that is successful or that is not adverse to the Fund, or that the Fund will outperform more traditional or benchmark-constrained fixed income funds. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation ("FDIC") 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. Investments in the Fund involve 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 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's liquidity and cause significant deterioration in net asset value ("NAV"). To the extent that the Fund invests in non-investment grade fixed income securities, these risks may be more pronounced.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Derivatives Risk&lt;/b&gt;.&amp;nbsp; Loss may result from the Fund's investments in options, futures, forwards, swaps and other derivative instruments. These instruments may be illiquid, difficult to price and leveraged so that small changes in the value of underlying instruments 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. Foreign exchange rates can be extremely volatile and a variance in the degree of volatility of the market or in the direction of the market from the Investment Adviser's expectations for non-hedging forward foreign currency transactions may produce significant losses to the Fund.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Floating and Variable Rate Obligations Risk&lt;/b&gt;.&amp;nbsp; For floating and variable rate obligations, there may be a lag between an actual change in the underlying interest rate benchmark and the reset time for an interest payment of such an obligation, which could harm or benefit the Fund, depending on the interest rate environment or other circumstances. In a rising interest rate environment, for example, a floating or variable rate obligation that does not reset immediately would prevent the Fund from taking full advantage of rising interest rates in a timely manner. However, in a declining interest rate environment, the Fund may benefit from a lag due to an obligation's interest rate payment not being immediately impacted by a decline in interest rates.&lt;br /&gt;&lt;br /&gt;Certain floating and variable rate obligations have an interest rate floor feature, which prevents the interest rate payable by the security from dropping below a specified level as compared to a reference interest rate (the "reference rate"), such as LIBOR. Such a floor protects the Fund from losses resulting from a decrease in the reference rate below the specified level. However, if the reference rate is below the floor, there will be a lag between a rise in the reference rate and a rise in the interest rate payable by the obligation, and the Fund may not benefit from increasing interest rates for a significant amount of time.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Foreign and Emerging Countries 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, sanctions, confiscations and other government restrictions by the United States and other governments, 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; 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;Large Shareholder Transactions Risk&lt;/b&gt;.&amp;nbsp; The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund's NAV and liquidity. Similarly, large Fund share purchases may adversely affect the Fund's performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also increase transaction costs. In addition, a large redemption could result in the Fund's current expenses being allocated over a smaller asset base, leading to an increase in the Fund's expense ratio.&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. Liquidity risk may be the result of, among other things, the reduced number and capacity of traditional market participants to make a market in fixed income securities or the lack of an active market. The potential for liquidity risk may be magnified by a rising interest rate environment or other circumstances where investor redemptions from fixed income mutual funds may be higher than normal, potentially causing increased supply in the market due to selling activity.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Loan-Related Investments Risk&lt;/b&gt;.&amp;nbsp; In addition to risks generally associated with debt investments, loan-related investments such as loan participations and assignments are subject to other risks. Although a loan obligation may be fully collateralized at the time of acquisition, the collateral may decline in value, be relatively illiquid, or lose all or substantially all of its value subsequent to investment. Many loan investments are subject to legal or contractual restrictions on resale and may be relatively illiquid and difficult to value. There is less readily available, reliable information about most loan investments than is the case for many other types of securities. Substantial increases in interest rates may cause an increase in loan obligation defaults. With respect to loan participations, the Fund may not always have direct recourse against a borrower if the borrower fails to pay scheduled principal and/or interest; may be subject to greater delays, expenses and risks than if the Fund had purchased a direct obligation of the borrower; and may be regarded as the creditor of the agent lender (rather than the borrower), subjecting the Fund to the creditworthiness of that lender as well. The market for loan obligations may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods. Because transactions in many loans are subject to extended trade settlement periods, the Fund may not receive the proceeds from the sale of a loan for a period after the sale. As a result, sale proceeds related to the sale of loans may not be available to make additional investments or to meet the Fund's redemption obligations for a period after the sale of the loans, and, as a result, the Fund may have to sell other investments or engage in borrowing transactions, such as borrowing from its credit facility, if necessary to raise cash to meet its obligations.&lt;br /&gt;&lt;br /&gt;Senior loans hold the most senior position in the capital structure of a business entity, and are typically secured with specific collateral, but are nevertheless usually rated below investment grade. Because second lien loans are subordinated or unsecured and thus lower in priority of payment to senior loans, they are subject to the additional risk that the cash flow of the borrower and property securing the loan or debt, if any, may be insufficient to meet scheduled payments after giving effect to the senior secured obligations of the borrower. Second lien loans generally have greater price volatility than senior loans and may be less liquid.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Management Risk&lt;/b&gt;.&amp;nbsp; A strategy used by the Investment Adviser may fail to produce the intended results.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Market Risk&lt;/b&gt;.&amp;nbsp; The 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;Mortgage-Backed and Other Asset-Backed Securities Risk&lt;/b&gt;.&amp;nbsp; Mortgage-related and other asset-backed securities are subject to certain additional risks, including "extension risk" (i.e., in periods of rising interest rates, issuers may pay principal later than expected) and "prepayment risk" (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). The Fund may purchase many types of U.S. Government securities, including those issued by the Federal National Mortgage Association ("Fannie Mae"), Federal Home Loan Mortgage Corporation ("Freddie Mac") and Federal Home Loan Banks. These securities are neither issued nor guaranteed by the United States Treasury and, therefore, are not backed by the full faith and credit of the United States. 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;Municipal Securities Risk&lt;/b&gt;.&amp;nbsp; Municipal securities are subject to credit/default risk, interest rate risk and certain additional risks. The Fund may be more sensitive to adverse economic, business or political developments if it invests a substantial portion of its assets in the bonds of similar projects (such as those relating to education, health care, housing, transportation, and utilities), industrial development bonds, or in particular types of municipal securities (such as general obligation bonds, private activity bonds and moral obligation bonds).&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Non-Investment Grade Fixed Income Securities Risk&lt;/b&gt;.&amp;nbsp; Non-investment grade fixed income securities and unrated securities of comparable credit quality (commonly known as "junk bonds") are considered speculative and are subject to the increased risk of an issuer's inability to meet principal and interest payment obligations. These securities may be subject to greater price volatility due to such factors as specific issuer developments, interest rate sensitivity, negative perceptions of the junk bond markets generally and less liquidity.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Short Position Risk&lt;/b&gt;.&amp;nbsp; The Fund may enter into a short position through a futures contract, an option or swap agreement or through short sales of any instrument that the Fund may purchase for investment. Taking short positions involves leverage of the Fund's assets and presents various risks. If the price of the underlying instrument or market on which the Fund has taken a short position increases, then the Fund will incur a loss equal to the increase in price from the time that the short position was entered into plus any related interest payments or other fees. Taking short positions involves the risk that losses may be disproportionate, may exceed the amount invested and may be unlimited.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Sovereign Default Risk&lt;/b&gt;.&amp;nbsp; An issuer of non-U.S. sovereign debt held by the Fund 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;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 ("Fannie Mae"), Federal Home Loan Mortgage Corporation ("Freddie Mac") 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 their 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>

The Fund&amp;#8217;s investments in loan participations and loan assignments may include, but are not limited to: (a) senior secured floating rate and fixed rate loans or debt (&amp;#8220;Senior Loans&amp;#8221;), (b) second lien or other subordinated or unsecured floating rate and fixed rate loans or debt (&amp;#8220;Second Lien Loans&amp;#8221;) and (c) other types of secured or unsecured loans with fixed, floating or variable interest rates. The Fund may invest in fixed income securities of any maturity.&lt;br /&gt;&lt;br /&gt;Non-investment grade fixed income securities are securities rated BB+, Ba1 or below by a nationally recognized statistical rating organization (&amp;#8220;NRSRO&amp;#8221;), or, if unrated, determined by the Investment Adviser to be of comparable credit quality.&lt;br /&gt;&lt;br /&gt;The Fund may invest in sovereign and corporate debt securities and other instruments of issuers in emerging market countries (&amp;#8220;emerging countries debt&amp;#8221;). Such investments may include sovereign debt issued by emerging countries that have sovereign ratings below investment grade or that are unrated. There is no limitation to the amount the Fund invests in non-investment grade or emerging market securities. From time to time, the Fund may also invest in preferred stock. The Fund&amp;#8217;s investments may be denominated in currencies other than the U.S. dollar.&lt;br /&gt;&lt;br /&gt;The Fund may engage in forward foreign currency transactions for both investment and hedging purposes. The Fund also intends to invest in other derivative instruments. Derivatives are instruments that have a value based on another instrument, exchange rate, interest rate or index. The Fund&amp;#8217;s investments in derivatives may include, in addition to forward foreign currency exchange contracts, futures contracts (including interest rate futures and treasury and sovereign bond futures), options (including options on futures contracts, swaps, bonds, stocks and indexes), swaps (including credit default, index, basis, total return, volatility, interest rate and currency swaps), and other forward contracts. The Fund may use derivatives instead of buying and selling bonds to manage duration, to gain exposure or to short individual securities or to gain exposure to a credit or asset backed index.&lt;br /&gt;&lt;br /&gt;The Fund may implement short positions and may do so by using swaps or futures, or through short sales of any instrument that the Fund may purchase for investment. For example, the Fund may enter into a futures contract pursuant to which it agrees to sell an asset (that it does not currently own) at a specified price at a specified point in the future. This gives the Fund a short position with respect to that asset. The Fund will benefit to the extent the asset decreases in value (and will be harmed to the extent the asset increases in value) between the time it enters into the futures contract and the agreed date of sale. Alternatively, the Fund may sell an instrument (e.g., a bond, or a futures contract) it does not own in anticipation of a decline in the market value of the instrument, and then borrow the instrument to make delivery to the buyer. In these transactions, the Fund is obligated to replace the instrument borrowed by purchasing it at the market price at the time of replacement.&lt;br /&gt;&lt;br /&gt;&amp;#8220;Strategic&amp;#8221; in the Fund&amp;#8217;s name means that the Fund seeks both current income and capital appreciation as elements of total return. The Fund attempts to exploit pricing anomalies throughout the global fixed income and currency markets. Additionally, the Fund uses short positions and derivatives for both investment and hedging purposes. The Fund may sell investments that the portfolio managers believe are no longer favorable with regard to these factors.&lt;br /&gt;&lt;br /&gt;The Fund&amp;#8217;s benchmark index is the Bank of America Merrill Lynch U.S. Dollar Three-Month LIBOR Constant Maturity Index.</rr:StrategyNarrativeTextBlock>

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01May2014_30Apr2015S000009353_MemberInstitutional_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 fixed income securities, including securities issued or guaranteed by the U.S. government, its agencies, instrumentalities or sponsored enterprises (&amp;#8220;U.S. Government Securities&amp;#8221;), corporate debt securities, privately issued adjustable rate and fixed rate mortgage loans or other mortgage-related securities (&amp;#8220;Mortgage-Backed Securities&amp;#8221;) and asset-backed securities. 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.&lt;br /&gt;&lt;br /&gt;The Fund may also engage in forward foreign currency transactions for both investment and hedging purposes. The Fund also intends to invest in derivatives, including (but not limited to) interest rate futures, interest rate swaps and credit default swaps, which are used primarily to hedge the Fund&amp;#8217;s portfolio risks, manage the Fund&amp;#8217;s duration and/or gain exposure to certain fixed income securities or indices.&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 sovereign and corporate debt securities and other instruments of issuers in emerging market countries (&amp;#8220;emerging countries debt&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. Securities will either be rated by a nationally recognized statistical rating organization (&amp;#8220;NRSRO&amp;#8221;) or, if unrated, determined by the Investment Adviser to be of comparable credit quality.&lt;br /&gt;&lt;br /&gt;The Fund&amp;#8217;s target duration range under normal interest rate conditions is expected to approximate that of the Index plus or minus one year, and over the ten years ended February 28, 2015, the duration of the Index has ranged between 3.71 and 5.65 years. &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;&lt;br /&gt;The Fund&amp;#8217;s benchmark index is the Barclays U.S. Aggregate Bond Index.</rr:StrategyNarrativeTextBlock>

  <rr:RiskNarrativeTextBlock contextRef="Duration_01May2014_30Apr2015S000009353_MemberInstitutional_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. Investments in the Fund involve 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 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 deterioration in net asset value (&amp;#8220;NAV&amp;#8221;).&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 options, forwards, interest rate futures, interest rate swaps, credit default swaps and other derivative instruments. These instruments may be illiquid, difficult to price and leveraged so that small changes in the value of underlying instruments 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;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, sanctions, confiscations and other government restrictions by the United States or other governments, 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;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;Large Shareholder Transactions Risk.&lt;/b&gt; &amp;nbsp;The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund&amp;#8217;s NAV and liquidity. Similarly, large Fund share purchases may adversely affect the Fund&amp;#8217;s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also increase transaction costs. In addition, a large redemption could result in the Fund&amp;#8217;s current expenses being allocated over a smaller asset base, leading to an increase in the Fund&amp;#8217;s expense ratio.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Mortgage-Backed and Other Asset-Backed Securities 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 their 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>

Floating rate and variable rate obligations are debt instruments issued by companies or other entities with interest rates that reset periodically (typically, daily, monthly, quarterly, or semi-annually) in response to changes in the market rate of interest on which the interest rate is based. The Fund considers &amp;#147;high quality&amp;#148; obligations to be (i) those rated AAA or Aaa by a nationally recognized statistical rating organization (&amp;#147;NRSRO&amp;#148;) at the time of purchase, or, if unrated, determined by the Investment Adviser to be of comparable credit quality, including repurchase agreements with counterparties rated AAA or Aaa by an NRSRO at the time of purchase, or, if unrated, determined by the Investment Adviser to be of comparable credit quality, and (ii) securities issued or guaranteed by the U.S. Government, its agencies, instrumentalities or sponsored enterprises (&amp;#147;U.S. Government Securities&amp;#148;), including securities representing an interest in or collateralized by adjustable rate and fixed rate mortgage loans or other mortgage-related securities (&amp;#147;Mortgage-Backed Securities&amp;#148;), and in repurchase agreements collateralized by U.S. Government Securities, with counterparties approved by the Investment Adviser pursuant to procedures approved by the Board of Trustees.

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%.

Similarly, large Fund share purchases may adversely affect the Fund&amp;#146;s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also increase transaction costs. In addition, a large redemption could result in the Fund&amp;#146;s current expenses being allocated over a smaller asset base, leading to an increase in the Fund&amp;#146;s expense ratio.&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. Liquidity risk may be the result of, among other things, the reduced number and capacity of traditional market participants to make a market in fixed income securities or the lack of an active market. The potential for liquidity risk may be magnified by a rising interest rate environment or other circumstances where investor redemptions from fixed income mutual funds may be higher than normal, potentially causing increased supply in the market due to selling activity.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Mortgage-Backed and Other Asset-Backed Securities Risk.&lt;/b&gt; &amp;nbsp;Mortgage-related and other asset-backed securities are subject to certain additional risks, including &amp;#147;extension risk&amp;#148; (i.e., in periods of rising interest rates, issuers may pay principal later than expected) and &amp;#147;prepayment risk&amp;#148; (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;#147;Fannie Mae&amp;#148;), Federal Home Loan Mortgage Corporation (&amp;#147;Freddie Mac&amp;#148;) 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 their 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>

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation ("FDIC") 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. Investments in the Fund involve 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;Different investment styles (e.g., "growth," "value" or "quantitative") 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;Large Shareholder Transactions Risk.&lt;/b&gt; &amp;nbsp;The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund's NAV and liquidity. Similarly, large Fund share purchases may adversely affect the Fund's performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also increase transaction costs. In addition, a large redemption could result in the Fund's current expenses being allocated over a smaller asset base, leading to an increase in the Fund's expense ratio.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Market Risk.&lt;/b&gt; &amp;nbsp;The value of the securities 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;Stock Risk.&lt;/b&gt; &amp;nbsp;Stock prices have historically risen and fallen in periodic cycles.

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;#146;s fundamental outlook deteriorates, because of valuation and price considerations, for risk management purposes or when a company is deemed to be misallocating capital.

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01May2014_30Apr2015S000009361_Member">The Fund attempts to replicate the aggregate price and yield performance of a benchmark index that measures the investment returns of large capitalization stocks. The Fund&amp;#146;s benchmark is the S&amp;amp;P 500&lt;sup&gt;&amp;reg;&lt;/sup&gt; Index. Under normal circumstances, the Fund will hold equity securities of approximately 500 different companies included in the S&amp;amp;P 500&lt;sup&gt;&amp;reg;&lt;/sup&gt; Index and will invest at least 80% of its net assets plus any borrowings for investment purposes (measured at time of purchase) (&amp;#147;Net Assets&amp;#148;) in equity type securities. To the extent that the Fund&amp;#146;s ability to invest in any of the companies included in the S&amp;amp;P 500&lt;sup&gt;&amp;reg;&lt;/sup&gt; Index is limited by applicable regulatory requirements, the Fund may invest in fewer than 500 companies, and may not be able to precisely replicate the performance of the S&amp;amp;P 500&lt;sup&gt;&amp;reg;&lt;/sup&gt; Index. Additionally, in an attempt to replicate the performance of companies in which it may be unable to invest, the Fund may overweight certain holdings (relative to the S&amp;amp;P 500&lt;sup&gt;&amp;reg;&lt;/sup&gt; Index) that have similar characteristics.&lt;br /&gt;&lt;br /&gt;The Fund&amp;#146;s passive equity process objective is to seek to remain fully invested in the equity market.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (&amp;#147;FDIC&amp;#148;) 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. Investments in the Fund involve substantial risks which prospective investors should consider carefully before investing.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Index Risk.&lt;/b&gt;&amp;nbsp; Unlike many investment companies, the Fund is not actively managed. As a result, the Fund will not typically dispose of a security unless the security is removed from the relevant index, even if the issuer is in financial trouble.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Large Shareholder Transactions Risk.&lt;/b&gt;&amp;nbsp; The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund&amp;#146;s net asset value (&amp;#147;NAV&amp;#148;) and liquidity. Similarly, large Fund share purchases may adversely affect the Fund&amp;#146;s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also increase transaction costs. In addition, a large redemption could result in the Fund&amp;#146;s current expenses being allocated over a smaller asset base, leading to an increase in the Fund&amp;#146;s expense ratio.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Market Risk.&lt;/b&gt;&amp;nbsp; The 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;Stock Risk.&lt;/b&gt;&amp;nbsp; Stock prices have historically risen and fallen in periodic cycles.

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. 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. Investments in the Fund involve substantial risks which prospective investors should consider carefully before investing.&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;#146;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;#146;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 sanctions, confiscations and other government restrictions by the United States and other governments, 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 government 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, the Fund&amp;#146;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;#146;s portfolio holdings may have an adverse impact on the Fund&amp;#146;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;Large Shareholder Transactions Risk.&lt;/b&gt; &amp;nbsp;The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund&amp;#146;s NAV and liquidity. Similarly, large Fund share purchases may adversely affect the Fund&amp;#146;s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also increase transaction costs. In addition, a large redemption could result in the Fund&amp;#146;s current expenses being allocated over a smaller asset base, leading to an increase in the Fund&amp;#146;s expense ratio.&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;#146;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. Liquidity risk may be the result of, among other things, the reduced number and capacity of traditional market participants to make a market in fixed income securities or the lack of an active market. The potential for liquidity risk may be magnified by a rising interest rate environment or other circumstances where investor redemptions from fixed income mutual funds may be higher than normal, potentially causing increased supply in the market due to selling activity.&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;Municipal Securities Risk.&lt;/b&gt; &amp;nbsp;Municipal securities are subject to credit/default risk, interest rate risk and certain additional risks. The Fund may be more sensitive to adverse economic, business or political developments if it invests a substantial portion of its assets in the debt securities of similar projects (such as those relating to education, health care, housing, transportation, and utilities), industrial development bonds, or in particular types of municipal securities (such as general obligation bonds, private activity bonds and moral obligation bonds).&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Regulatory Risk.&lt;/b&gt; &amp;nbsp;The Securities and Exchange Commission (&amp;#147;SEC&amp;#148;) recently adopted changes to the rules that govern money market funds. These changes will: (1) permit, subject to the discretion of the Board of Trustees, money market funds to impose a &amp;#147;liquidity fee&amp;#148; (up to 2%) and/or &amp;#147;gates&amp;#148; that temporarily restrict redemptions from the funds, if weekly liquidity levels fall below the required regulatory threshold, and (2) require &amp;#147;institutional&amp;#148; money market funds to operate with a floating NAV rounded to the fourth decimal place. These changes may affect the Fund&amp;#146;s investment strategies, operations and/or return potential. As of the date of this Prospectus, the Investment Adviser is evaluating the potential impact of these changes which have a phase-in compliance period ranging from July 2015 through October 2016.&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;#146;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;#147;Fannie Mae&amp;#148;), Federal Home Loan Mortgage Corporation (&amp;#147;Freddie Mac&amp;#148;) 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>

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01May2014_30Apr2015S000009362_MemberService_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;#147;Net Assets&amp;#148;) in high quality floating rate or variable rate obligations. Floating rate and variable rate obligations are debt instruments issued by companies or other entities with interest rates that reset periodically (typically, daily, monthly, quarterly, or semi-annually) in response to changes in the market rate of interest on which the interest rate is based. The Fund considers &amp;#147;high quality&amp;#148; obligations to be (i) those rated AAA or Aaa by a nationally recognized statistical rating organization (&amp;#147;NRSRO&amp;#148;) at the time of purchase, or, if unrated, determined by the Investment Adviser to be of comparable credit quality, including repurchase agreements with counterparties rated AAA or Aaa by an NRSRO at the time of purchase, or, if unrated, determined by the Investment Adviser to be of comparable credit quality, and (ii) securities issued or guaranteed by the U.S. Government, its agencies, instrumentalities or sponsored enterprises (&amp;#147;U.S. Government Securities&amp;#148;), including securities representing an interest in or collateralized by adjustable rate and fixed rate mortgage loans or other mortgage-related securities (&amp;#147;Mortgage-Backed Securities&amp;#148;), and in repurchase agreements collateralized by U.S. Government Securities, with counterparties approved by the Investment Adviser pursuant to procedures approved by the Board of Trustees. The remainder of the Fund&amp;#146;s Net Assets (up to 20%) may include, but are not limited to, fixed rate obligations (subject to the credit quality requirements specified above). 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;#146;s duration. The Fund may invest in obligations of foreign issuers (including obligations issued by foreign governments and their agencies, instrumentalities or sponsored enterprises), although 100% of the Fund&amp;#146;s portfolio will be invested in U.S. dollar denominated securities.&lt;br /&gt;&lt;br /&gt;The Fund&amp;#146;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;#147;FFELP&amp;#148;) 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;#146;s target duration range under normal interest rate conditions is expected to approximate that of the Bank of America Merrill Lynch Three-Month U.S. Treasury Bill Index, plus or minus 1 year, and the duration of this index is typically approximately three months. &amp;#147;Duration&amp;#148; is a measure of a debt security&amp;#146;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;#146;s market price.&lt;br /&gt;&lt;br /&gt;The Fund&amp;#146;s benchmark index is the Bank of America Merrill Lynch Three-Month U.S. Treasury Bill Index.&lt;br /&gt;&lt;br /&gt;GSAM&amp;#146;s Fixed Income Investing Philosophy:&lt;br /&gt;Global fixed income markets are constantly evolving and are highly diverse&amp;#8212;with a large number of countries, currencies, sectors, issuers and securities.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (&amp;#147;FDIC&amp;#148;) 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. Investments in the Fund involve 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;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, sanctions, confiscations and other government restrictions by the United States and other governments, 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 the Fund also invests in securities of issuers located in emerging countries, these risks may be more pronounced.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Large Shareholder Transactions Risk.&lt;/b&gt; &amp;nbsp;The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund.

Similarly, large Fund share purchases may adversely affect the Fund&amp;#146;s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also increase transaction costs. In addition, a large redemption could result in the Fund&amp;#146;s current expenses being allocated over a smaller asset base, leading to an increase in the Fund&amp;#146;s expense ratio.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Market Risk.&lt;/b&gt; &amp;nbsp;The 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;Stock Risk.&lt;/b&gt; &amp;nbsp;Stock prices have historically risen and fallen in periodic cycles.

Additionally, the credit quality of securities may deteriorate rapidly, which may impair the Fund&amp;#146;s liquidity and cause significant deterioration in net asset value (&amp;#147;NAV&amp;#148;).&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Derivatives Risk.&lt;/b&gt;&amp;nbsp; Loss may result from the Fund&amp;#146;s investments in options, futures, swaps and other derivative instruments. These instruments may be illiquid, difficult to price and leveraged so that small changes in the value of underlying instruments 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, sanctions, confiscations and other government restrictions by the United States and other governments, 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;Large Shareholder Transactions Risk.&lt;/b&gt;&amp;nbsp; The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund&amp;#146;s NAV and liquidity. Similarly, large Fund share purchases may adversely affect the Fund&amp;#146;s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

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. Liquidity risk may be the result of, among other things, the reduced number and capacity of traditional market participants to make a market in fixed income securities or the lack of an active market. The potential for liquidity risk may be magnified by a rising interest rate environment or other circumstances where investor redemptions from fixed income mutual funds may be higher than normal, potentially causing increased supply in the market due to selling activity.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Mortgage-Backed and Other Asset-Backed Securities Risk.&lt;/b&gt;&amp;nbsp; Mortgage-related and other asset-backed securities are subject to certain additional risks, including &amp;#147;extension risk&amp;#148; (i.e., in periods of rising interest rates, issuers may pay principal later than expected) and &amp;#147;prepayment risk&amp;#148; (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;#147;Fannie Mae&amp;#148;), Federal Home Loan Mortgage Corporation (&amp;#147;Freddie Mac&amp;#148;) 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 their 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>

The Investment Adviser may decide to sell a position for various reasons including when a company&amp;#146;s fundamental outlook deteriorates, because of valuation and price considerations, for risk management purposes or when a company is deemed to be misallocating capital.

  <rr:RiskNarrativeTextBlock contextRef="Duration_01May2014_30Apr2015S000009354_MemberService_Member">An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (&amp;#147;FDIC&amp;#148;) or any government agency. 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. 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. Investments in the Fund involve substantial risks which prospective investors should consider carefully before investing.&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;#146;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;#146;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 sanctions, confiscations and other government restrictions by the United States and other governments, 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 government 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, the Fund&amp;#146;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;#146;s portfolio holdings may have an adverse impact on the Fund&amp;#146;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;Large Shareholder Transactions Risk.&lt;/b&gt; &amp;nbsp;The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund&amp;#146;s NAV and liquidity. Similarly, large Fund share purchases may adversely affect the Fund&amp;#146;s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also increase transaction costs. In addition, a large redemption could result in the Fund&amp;#146;s current expenses being allocated over a smaller asset base, leading to an increase in the Fund&amp;#146;s expense ratio.&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;#146;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. Liquidity risk may be the result of, among other things, the reduced number and capacity of traditional market participants to make a market in fixed income securities or the lack of an active market. The potential for liquidity risk may be magnified by a rising interest rate environment or other circumstances where investor redemptions from fixed income mutual funds may be higher than normal, potentially causing increased supply in the market due to selling activity.&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;Municipal Securities Risk.&lt;/b&gt; &amp;nbsp;Municipal securities are subject to credit/default risk, interest rate risk and certain additional risks. The Fund may be more sensitive to adverse economic, business or political developments if it invests a substantial portion of its assets in the debt securities of similar projects (such as those relating to education, health care, housing, transportation, and utilities), industrial development bonds, or in particular types of municipal securities (such as general obligation bonds, private activity bonds and moral obligation bonds).&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Regulatory Risk.&lt;/b&gt; &amp;nbsp;The Securities and Exchange Commission (&amp;#147;SEC&amp;#148;) recently adopted changes to the rules that govern money market funds. These changes will: (1) permit, subject to the discretion of the Board of Trustees, money market funds to impose a &amp;#147;liquidity fee&amp;#148; (up to 2%) and/or &amp;#147;gates&amp;#148; that temporarily restrict redemptions from the funds, if weekly liquidity levels fall below the required regulatory threshold, and (2) require &amp;#147;institutional&amp;#148; money market funds to operate with a floating NAV rounded to the fourth decimal place. These changes may affect the Fund&amp;#146;s investment strategies, operations and/or return potential. As of the date of this Prospectus, the Investment Adviser is evaluating the potential impact of these changes which have a phase-in compliance period ranging from July 2015 through October 2016.&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;#146;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;#147;Fannie Mae&amp;#148;), Federal Home Loan Mortgage Corporation (&amp;#147;Freddie Mac&amp;#148;) 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>

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01May2014_30Apr2015S000009358_MemberService_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;#147;Net Assets&amp;#148;) in a diversified portfolio of equity investments in mid-cap issuers with public stock market capitalizations within the range of the market capitalization of companies constituting the Russell Midcap&amp;#174; Value Index at the time of investment. As of April 1, 2015, the capitalization range of the Russell Midcap&amp;#174; Value Index was between approximately $212 million and $34 billion. Although the Fund will invest primarily in publicly traded U.S. securities, including real estate investment trusts (&amp;#147;REITS&amp;#148;), it may invest in foreign securities, including securities of issuers in countries with emerging markets or economies (&amp;#147;emerging countries&amp;#148;) and securities quoted in foreign currencies.&lt;br /&gt;&lt;br /&gt;The Fund&amp;#146;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;#146;s outlook based on subsequent events, the Investment Adviser&amp;#146;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.&lt;br /&gt;&lt;br /&gt;The Fund&amp;#146;s benchmark index is the Russell Midcap&amp;#174; Value Index.</rr:StrategyNarrativeTextBlock>

  <rr:RiskNarrativeTextBlock contextRef="Duration_01May2014_30Apr2015S000009358_MemberService_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;#147;FDIC&amp;#148;) 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. Investments in the Fund involve 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;Different investment styles (e.g., &amp;#147;growth,&amp;#148; &amp;#147;value&amp;#148; or &amp;#147;quantitative&amp;#148;) 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;Large Shareholder Transactions Risk.&lt;/b&gt; &amp;nbsp;The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund&amp;#146;s net asset value (&amp;#147;NAV&amp;#148;) and liquidity. Similarly, large Fund share purchases may adversely affect the Fund&amp;#146;s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also increase transaction costs. In addition, a large redemption could result in the Fund&amp;#146;s current expenses being allocated over a smaller asset base, leading to an increase in the Fund&amp;#146;s expense ratio.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Market Risk.&lt;/b&gt; &amp;nbsp;The 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;Mid-Cap and Small-Cap Risk.&lt;/b&gt; &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;REIT Risk.&lt;/b&gt; &amp;nbsp;Risks associated with investments such as REITs in the real estate industry include, among others: possible declines in the value of real estate; risks related to general and local economic conditions; possible lack of availability of mortgage financing, variations in rental income, neighborhood values or the appeal of property to tenants; interest rates; overbuilding; extended vacancies of properties; increases in competition, property taxes and operating expenses; and changes in zoning laws. REITs whose underlying properties are concentrated in a particular industry or geographic region are subject to risks affecting such industries and regions. The securities of REITs involve greater risks than those associated with larger, more established companies and may be subject to more abrupt or erratic price movements because of interest rate changes, economic conditions and other factors.

A high rate of portfolio turnover may result in increased transaction costs, which must be borne by the Fund and its shareholders. These costs are not reflected in annual fund operating expenses or in the expense example above, but are reflected in the Fund&amp;#146;s performance.

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01May2014_30Apr2015S000043924_MemberInstitutional_Member">The Fund invests in a broadly diversified portfolio of U.S. and foreign investment grade and non-investment grade fixed income investments including, but not limited to: U.S. Government securities (such as U.S. Treasury securities or Treasury inflation protected securities), non-U.S. sovereign debt, agency securities, corporate debt securities, agency and non-agency mortgage-backed securities, asset-backed securities, custodial receipts, municipal securities, loan participations and loan assignments and convertible securities. The Fund&amp;#146;s investments in loan participations and loan assignments may include, but are not limited to: (a) senior secured floating rate and fixed rate loans or debt (&amp;#147;Senior Loans&amp;#148;), (b) second lien or other subordinated or unsecured floating rate and fixed rate loans or debt (&amp;#147;Second Lien Loans&amp;#148;) and (c) other types of secured or unsecured loans with fixed, floating or variable interest rates. The Fund may invest in fixed income securities of any maturity.&lt;br /&gt;&lt;br /&gt;Non-investment grade fixed income securities are securities rated BB+, Ba1 or below by a nationally recognized statistical rating organization (&amp;#147;NRSRO&amp;#148;), or, if unrated, determined by the Investment Adviser to be of comparable credit quality.&lt;br /&gt;&lt;br /&gt;The Fund may invest in sovereign and corporate debt securities and other instruments of issuers in emerging market countries (&amp;#147;emerging countries debt&amp;#148;). Such investments may include sovereign debt issued by emerging countries that have sovereign ratings below investment grade or that are unrated. There is no limitation to the amount the Fund invests in non-investment grade or emerging market securities. From time to time, the Fund may also invest in preferred stock. The Fund&amp;#146;s investments may be denominated in currencies other than the U.S. dollar.&lt;br /&gt;&lt;br /&gt;The Fund may engage in forward foreign currency transactions for both investment and hedging purposes. The Fund also intends to invest in other derivative instruments. Derivatives are instruments that have a value based on another instrument, exchange rate, interest rate or index. The Fund&amp;#146;s investments in derivatives may include, in addition to forward foreign currency exchange contracts, futures contracts (including interest rate futures and treasury and sovereign bond futures), options (including options on futures contracts, swaps, bonds, stocks and indexes), swaps (including credit default, index, basis, total return, volatility, interest rate and currency swaps), and other forward contracts. The Fund may use derivatives instead of buying and selling bonds to manage duration, to gain exposure or to short individual securities or to gain exposure to a credit or asset backed index.&lt;br /&gt;&lt;br /&gt;The Fund may implement short positions and may do so by using swaps or futures, or through short sales of any instrument that the Fund may purchase for investment. For example, the Fund may enter into a futures contract pursuant to which it agrees to sell an asset (that it does not currently own) at a specified price at a specified point in the future. This gives the Fund a short position with respect to that asset. The Fund will benefit to the extent the asset decreases in value (and will be harmed to the extent the asset increases in value) between the time it enters into the futures contract and the agreed date of sale. Alternatively, the Fund may sell an instrument (e.g., a bond, or a futures contract) it does not own in anticipation of a decline in the market value of the instrument, and then borrow the instrument to make delivery to the buyer. In these transactions, the Fund is obligated to replace the instrument borrowed by purchasing it at the market price at the time of replacement.&lt;br /&gt;&lt;br /&gt;&amp;#147;Strategic&amp;#148; in the Fund&amp;#146;s name means that the Fund seeks both current income and capital appreciation as elements of total return. The Fund attempts to exploit pricing anomalies throughout the global fixed income and currency markets. Additionally, the Fund uses short positions and derivatives for both investment and hedging purposes. The Fund may sell investments that the portfolio managers believe are no longer favorable with regard to these factors.&lt;br /&gt;&lt;br /&gt;The Fund&amp;#146;s benchmark index is the Bank of America Merrill Lynch U.S. Dollar Three-Month LIBOR Constant Maturity Index.</rr:StrategyNarrativeTextBlock>

  <rr:RiskNarrativeTextBlock contextRef="Duration_01May2014_30Apr2015S000043924_MemberInstitutional_Member">&lt;b&gt;Loss of money is a risk of investing in the Fund. The Investment Adviser will not manage the investment program of the Fund by reference to a benchmark index (i.e., unconstrained). By removing benchmark constraints, the Fund is able to invest across the global fixed income spectrum without regard to sector, quality, maturity or market capitalization limitations, including in asset classes in which more traditional or benchmark-constrained fixed income funds do not typically invest (or do not invest to such an extent). Due to this flexible strategy, the Fund&amp;#146;s risk exposure may vary, and the Fund may underperform traditional fixed income indices. There can be no assurance that the discretionary element of the investment processes of the Investment Adviser will be exercised in a manner that is successful or that is not adverse to the Fund, or that the Fund will outperform more traditional or benchmark-constrained fixed income funds. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (&amp;#147;FDIC&amp;#148;) 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. Investments in the Fund involve substantial risks which prospective investors should consider carefully before investing.&lt;/b&gt;&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 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;#146;s liquidity and cause significant deterioration in net asset value (&amp;#147;NAV&amp;#148;). To the extent that the Fund invests in non-investment grade fixed income securities, these risks may be more pronounced.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Derivatives Risk.&lt;/b&gt; &amp;nbsp;Loss may result from the Fund&amp;#146;s investments in options, futures, forwards, swaps and other derivative instruments. These instruments may be illiquid, difficult to price and leveraged so that small changes in the value of underlying instruments 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. Foreign exchange rates can be extremely volatile and a variance in the degree of volatility of the market or in the direction of the market from the Investment Adviser&amp;#146;s expectations for non-hedging forward foreign currency transactions may produce significant losses to the Fund.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Floating and Variable Rate Obligations Risk.&lt;/b&gt; &amp;nbsp;For floating and variable rate obligations, there may be a lag between an actual change in the underlying interest rate benchmark and the reset time for an interest payment of such an obligation, which could harm or benefit the Fund, depending on the interest rate environment or other circumstances. In a rising interest rate environment, for example, a floating or variable rate obligation that does not reset immediately would prevent the Fund from taking full advantage of rising interest rates in a timely manner. However, in a declining interest rate environment, the Fund may benefit from a lag due to an obligation&amp;#146;s interest rate payment not being immediately impacted by a decline in interest rates.&lt;br /&gt;&lt;br /&gt;Certain floating and variable rate obligations have an interest rate floor feature, which prevents the interest rate payable by the security from dropping below a specified level as compared to a reference interest rate (the &amp;#147;reference rate&amp;#148;), such as LIBOR. Such a floor protects the Fund from losses resulting from a decrease in the reference rate below the specified level. However, if the reference rate is below the floor, there will be a lag between a rise in the reference rate and a rise in the interest rate payable by the obligation, and the Fund may not benefit from increasing interest rates for a significant amount of time.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Foreign and Emerging Countries 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, sanctions, confiscations and other government restrictions by the United States and other governments, 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;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;Large Shareholder Transactions Risk.&lt;/b&gt; &amp;nbsp;The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund&amp;#146;s NAV and liquidity. Similarly, large Fund share purchases may adversely affect the Fund&amp;#146;s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also increase transaction costs. In addition, a large redemption could result in the Fund&amp;#146;s current expenses being allocated over a smaller asset base, leading to an increase in the Fund&amp;#146;s expense ratio.&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. Liquidity risk may be the result of, among other things, the reduced number and capacity of traditional market participants to make a market in fixed income securities or the lack of an active market. The potential for liquidity risk may be magnified by a rising interest rate environment or other circumstances where investor redemptions from fixed income mutual funds may be higher than normal, potentially causing increased supply in the market due to selling activity.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Loan-Related Investments Risk.&lt;/b&gt; &amp;nbsp;In addition to risks generally associated with debt investments, loan-related investments such as loan participations and assignments are subject to other risks. Although a loan obligation may be fully collateralized at the time of acquisition, the collateral may decline in value, be relatively illiquid, or lose all or substantially all of its value subsequent to investment. Many loan investments are subject to legal or contractual restrictions on resale and may be relatively illiquid and difficult to value. There is less readily available, reliable information about most loan investments than is the case for many other types of securities. Substantial increases in interest rates may cause an increase in loan obligation defaults. With respect to loan participations, the Fund may not always have direct recourse against a borrower if the borrower fails to pay scheduled principal and/or interest; may be subject to greater delays, expenses and risks than if the Fund had purchased a direct obligation of the borrower; and may be regarded as the creditor of the agent lender (rather than the borrower), subjecting the Fund to the creditworthiness of that lender as well. The market for loan obligations may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods. Because transactions in many loans are subject to extended trade settlement periods, the Fund may not receive the proceeds from the sale of a loan for a period after the sale. As a result, sale proceeds related to the sale of loans may not be available to make additional investments or to meet the Fund&amp;#146;s redemption obligations for a period after the sale of the loans, and, as a result, the Fund may have to sell other investments or engage in borrowing transactions, such as borrowing from its credit facility, if necessary to raise cash to meet its obligations.&lt;br /&gt;&lt;br /&gt;Senior loans hold the most senior position in the capital structure of a business entity, and are typically secured with specific collateral, but are nevertheless usually rated below investment grade. Because second lien loans are subordinated or unsecured and thus lower in priority of payment to senior loans, they are subject to the additional risk that the cash flow of the borrower and property securing the loan or debt, if any, may be insufficient to meet scheduled payments after giving effect to the senior secured obligations of the borrower. Second lien loans generally have greater price volatility than senior loans and may be less liquid.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Management Risk.&lt;/b&gt; &amp;nbsp;A strategy used by the Investment Adviser may fail to produce the intended results.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Market Risk.&lt;/b&gt; &amp;nbsp;The 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;Mortgage-Backed and Other Asset-Backed Securities Risk.&lt;/b&gt; &amp;nbsp;Mortgage-related and other asset-backed securities are subject to certain additional risks, including &amp;#147;extension risk&amp;#148; (i.e., in periods of rising interest rates, issuers may pay principal later than expected) and &amp;#147;prepayment risk&amp;#148; (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). The Fund may purchase many types of U.S. Government securities, including those issued by the Federal National Mortgage Association (&amp;#147;Fannie Mae&amp;#148;), Federal Home Loan Mortgage Corporation (&amp;#147;Freddie Mac&amp;#148;) and Federal Home Loan Banks. These securities are neither issued nor guaranteed by the United States Treasury and, therefore, are not backed by the full faith and credit of the United States. 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;Municipal Securities Risk.&lt;/b&gt; &amp;nbsp;Municipal securities are subject to credit/default risk, interest rate risk and certain additional risks. The Fund may be more sensitive to adverse economic, business or political developments if it invests a substantial portion of its assets in the bonds of similar projects (such as those relating to education, health care, housing, transportation, and utilities), industrial development bonds, or in particular types of municipal securities (such as general obligation bonds, private activity bonds and moral obligation bonds).&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Non-Investment Grade Fixed Income Securities Risk.  &lt;/b&gt; &amp;nbsp;Non-investment grade fixed income securities and unrated securities of comparable credit quality (commonly known as &amp;#147;junk bonds&amp;#148;) are considered speculative and are subject to the increased risk of an issuer&amp;#146;s inability to meet principal and interest payment obligations. These securities may be subject to greater price volatility due to such factors as specific issuer developments, interest rate sensitivity, negative perceptions of the junk bond markets generally and less liquidity.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Short Position Risk.&lt;/b&gt; &amp;nbsp;The Fund may enter into a short position through a futures contract, an option or swap agreement or through short sales of any instrument that the Fund may purchase for investment. Taking short positions involves leverage of the Fund&amp;#146;s assets and presents various risks. If the price of the underlying instrument or market on which the Fund has taken a short position increases, then the Fund will incur a loss equal to the increase in price from the time that the short position was entered into plus any related interest payments or other fees. Taking short positions involves the risk that losses may be disproportionate, may exceed the amount invested and may be unlimited.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Sovereign Default Risk.&lt;/b&gt; &amp;nbsp;An issuer of non-U.S. sovereign debt held by the Fund 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;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;#147;Fannie Mae&amp;#148;), Federal Home Loan Mortgage Corporation (&amp;#147;Freddie Mac&amp;#148;) 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 their 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>

The Fund&amp;#146;s investments in loan participations and loan assignments may include, but are not limited to: (a) senior secured floating rate and fixed rate loans or debt (&amp;#147;Senior Loans&amp;#148;), (b) second lien or other subordinated or unsecured floating rate and fixed rate loans or debt (&amp;#147;Second Lien Loans&amp;#148;) and (c) other types of secured or unsecured loans with fixed, floating or variable interest rates. The Fund may invest in fixed income securities of any maturity.&lt;br /&gt;&lt;br /&gt; Non-investment grade fixed income securities are securities rated BB+, Ba1 or below by a nationally recognized statistical rating organization (&amp;#147;NRSRO&amp;#148;), or, if unrated, determined by the Investment Adviser to be of comparable credit quality.&lt;br /&gt;&lt;br /&gt;The Fund may invest in sovereign and corporate debt securities and other instruments of issuers in emerging market countries (&amp;#147;emerging countries debt&amp;#148;). Such investments may include sovereign debt issued by emerging countries that have sovereign ratings below investment grade or that are unrated. There is no limitation to the amount the Fund invests in non-investment grade or emerging market securities. From time to time, the Fund may also invest in preferred stock. The Fund&amp;#146;s investments may be denominated in currencies other than the U.S. dollar.&lt;br /&gt;&lt;br /&gt;The Fund may engage in forward foreign currency transactions for both investment and hedging purposes. The Fund also intends to invest in other derivative instruments. Derivatives are instruments that have a value based on another instrument, exchange rate, interest rate or index. The Fund&amp;#146;s investments in derivatives may include, in addition to forward foreign currency exchange contracts, futures contracts (including interest rate futures and treasury and sovereign bond futures), options (including options on futures contracts, swaps, bonds, stocks and indexes), swaps (including credit default, index, basis, total return, volatility, interest rate and currency swaps), and other forward contracts. The Fund may use derivatives instead of buying and selling bonds to manage duration, to gain exposure or to short individual securities or to gain exposure to a credit or asset backed index.&lt;br /&gt;&lt;br /&gt;The Fund may implement short positions and may do so by using swaps or futures, or through short sales of any instrument that the Fund may purchase for investment. For example, the Fund may enter into a futures contract pursuant to which it agrees to sell an asset (that it does not currently own) at a specified price at a specified point in the future. This gives the Fund a short position with respect to that asset. The Fund will benefit to the extent the asset decreases in value (and will be harmed to the extent the asset increases in value) between the time it enters into the futures contract and the agreed date of sale. Alternatively, the Fund may sell an instrument (e.g., a bond, or a futures contract) it does not own in anticipation of a decline in the market value of the instrument, and then borrow the instrument to make delivery to the buyer. In these transactions, the Fund is obligated to replace the instrument borrowed by purchasing it at the market price at the time of replacement.&lt;br /&gt;&lt;br /&gt;&amp;#147;Strategic&amp;#148; in the Fund&amp;#146;s name means that the Fund seeks both current income and capital appreciation as elements of total return. The Fund attempts to exploit pricing anomalies throughout the global fixed income and currency markets. Additionally, the Fund uses short positions and derivatives for both investment and hedging purposes. The Fund may sell investments that the portfolio managers believe are no longer favorable with regard to these factors.&lt;br /&gt;&lt;br /&gt;The Fund&amp;#146;s benchmark index is the Bank of America Merrill Lynch U.S. Dollar Three-Month LIBOR Constant Maturity Index.</rr:StrategyNarrativeTextBlock>

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01May2014_30Apr2015S000009355_MemberInstitutional_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;#147;Net Assets&amp;#148;) 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&gt;&amp;#174;&lt;/sup&gt; Index at the time of investment, which as of February 1, 2015 was between approximately $16 million and $11.2 billion. However, the Fund may invest in securities outside the Russell 2000&lt;sup&gt;&amp;#174;&lt;/sup&gt; Index capitalization range.&lt;br /&gt;&lt;br /&gt;The Fund uses a 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;#146;s investments are selected using fundamental research and a variety of quantitative techniques based on certain investment themes, including, among others, Momentum, Valuation and Profitability. 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 Valuation theme attempts to capture potential mispricings of securities, typically by comparing a measure of the company&amp;#146;s intrinsic value to its market value. The Profitability theme seeks to assess whether a company is earning more than its cost of capital. 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;#146;s proprietary research.&lt;br /&gt;&lt;br /&gt;The Fund maintains risk, style, and capitalization characteristics similar to the Russell 2000&lt;sup&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;#146;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.&lt;br /&gt;&lt;br /&gt;The Fund&amp;#146;s benchmark index is the Russell 2000&lt;sup&gt;&amp;#174;&lt;/sup&gt; Index.</rr:StrategyNarrativeTextBlock>

  <rr:RiskNarrativeTextBlock contextRef="Duration_01May2014_30Apr2015S000043924_MemberService_Member">&lt;b&gt;Loss of money is a risk of investing in the Fund. The Investment Adviser will not manage the investment program of the Fund by reference to a benchmark index (i.e., unconstrained). By removing benchmark constraints, the Fund is able to invest across the global fixed income spectrum without regard to sector, quality, maturity or market capitalization limitations, including in asset classes in which more traditional or benchmark-constrained fixed income funds do not typically invest (or do not invest to such an extent). Due to this flexible strategy, the Fund&amp;#146;s risk exposure may vary, and the Fund may underperform traditional fixed income indices. There can be no assurance that the discretionary element of the investment processes of the Investment Adviser will be exercised in a manner that is successful or that is not adverse to the Fund, or that the Fund will outperform more traditional or benchmark-constrained fixed income funds. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (&amp;#147;FDIC&amp;#148;) 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. Investments in the Fund involve substantial risks which prospective investors should consider carefully before investing.&lt;/b&gt;&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 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;#146;s liquidity and cause significant deterioration in net asset value (&amp;#147;NAV&amp;#148;). To the extent that the Fund invests in non-investment grade fixed income securities, these risks may be more pronounced.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Derivatives Risk.&lt;/b&gt; &amp;nbsp;Loss may result from the Fund&amp;#146;s investments in options, futures, forwards, swaps and other derivative instruments. These instruments may be illiquid, difficult to price and leveraged so that small changes in the value of underlying instruments 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. Foreign exchange rates can be extremely volatile and a variance in the degree of volatility of the market or in the direction of the market from the Investment Adviser&amp;#146;s expectations for non-hedging forward foreign currency transactions may produce significant losses to the Fund.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Floating and Variable Rate Obligations Risk.&lt;/b&gt; &amp;nbsp;For floating and variable rate obligations, there may be a lag between an actual change in the underlying interest rate benchmark and the reset time for an interest payment of such an obligation, which could harm or benefit the Fund, depending on the interest rate environment or other circumstances. In a rising interest rate environment, for example, a floating or variable rate obligation that does not reset immediately would prevent the Fund from taking full advantage of rising interest rates in a timely manner. However, in a declining interest rate environment, the Fund may benefit from a lag due to an obligation&amp;#146;s interest rate payment not being immediately impacted by a decline in interest rates.&lt;br /&gt;&lt;br /&gt;Certain floating and variable rate obligations have an interest rate floor feature, which prevents the interest rate payable by the security from dropping below a specified level as compared to a reference interest rate (the "reference rate"), such as LIBOR. Such a floor protects the Fund from losses resulting from a decrease in the reference rate below the specified level. However, if the reference rate is below the floor, there will be a lag between a rise in the reference rate and a rise in the interest rate payable by the obligation, and the Fund may not benefit from increasing interest rates for a significant amount of time.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Foreign and Emerging Countries 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, sanctions, confiscations and other government restrictions by the United States and other governments, 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;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;Large Shareholder Transactions Risk.&lt;/b&gt; &amp;nbsp;The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund&amp;#146;s NAV and liquidity. Similarly, large Fund share purchases may adversely affect the Fund&amp;#146;s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also increase transaction costs. In addition, a large redemption could result in the Fund&amp;#146;s current expenses being allocated over a smaller asset base, leading to an increase in the Fund&amp;#146;s expense ratio.&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. Liquidity risk may be the result of, among other things, the reduced number and capacity of traditional market participants to make a market in fixed income securities or the lack of an active market. The potential for liquidity risk may be magnified by a rising interest rate environment or other circumstances where investor redemptions from fixed income mutual funds may be higher than normal, potentially causing increased supply in the market due to selling activity.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Loan-Related Investments Risk.&lt;/b&gt; &amp;nbsp;In addition to risks generally associated with debt investments, loan-related investments such as loan participations and assignments are subject to other risks. Although a loan obligation may be fully collateralized at the time of acquisition, the collateral may decline in value, be relatively illiquid, or lose all or substantially all of its value subsequent to investment. Many loan investments are subject to legal or contractual restrictions on resale and may be relatively illiquid and difficult to value. There is less readily available, reliable information about most loan investments than is the case for many other types of securities. Substantial increases in interest rates may cause an increase in loan obligation defaults. With respect to loan participations, the Fund may not always have direct recourse against a borrower if the borrower fails to pay scheduled principal and/or interest; may be subject to greater delays, expenses and risks than if the Fund had purchased a direct obligation of the borrower; and may be regarded as the creditor of the agent lender (rather than the borrower), subjecting the Fund to the creditworthiness of that lender as well. The market for loan obligations may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods. Because transactions in many loans are subject to extended trade settlement periods, the Fund may not receive the proceeds from the sale of a loan for a period after the sale. As a result, sale proceeds related to the sale of loans may not be available to make additional investments or to meet the Fund&amp;#146;s redemption obligations for a period after the sale of the loans, and, as a result, the Fund may have to sell other investments or engage in borrowing transactions, such as borrowing from its credit facility, if necessary to raise cash to meet its obligations.&lt;br /&gt;&lt;br /&gt;Senior loans hold the most senior position in the capital structure of a business entity, and are typically secured with specific collateral, but are nevertheless usually rated below investment grade. Because second lien loans are subordinated or unsecured and thus lower in priority of payment to senior loans, they are subject to the additional risk that the cash flow of the borrower and property securing the loan or debt, if any, may be insufficient to meet scheduled payments after giving effect to the senior secured obligations of the borrower. Second lien loans generally have greater price volatility than senior loans and may be less liquid.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Management Risk.&lt;/b&gt; &amp;nbsp;A strategy used by the Investment Adviser may fail to produce the intended results.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Market Risk.&lt;/b&gt; &amp;nbsp;The 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;Mortgage-Backed and Other Asset-Backed Securities Risk.&lt;/b&gt; &amp;nbsp;Mortgage-related and other asset-backed securities are subject to certain additional risks, including &amp;#147;extension risk&amp;#148; (i.e., in periods of rising interest rates, issuers may pay principal later than expected) and &amp;#147;prepayment risk&amp;#148; (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). The Fund may purchase many types of U.S. Government securities, including those issued by the Federal National Mortgage Association (&amp;#147;Fannie Mae&amp;#148;), Federal Home Loan Mortgage Corporation (&amp;#147;Freddie Mac&amp;#148;) and Federal Home Loan Banks. These securities are neither issued nor guaranteed by the United States Treasury and, therefore, are not backed by the full faith and credit of the United States. 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;Municipal Securities Risk.&lt;/b&gt; &amp;nbsp;Municipal securities are subject to credit/default risk, interest rate risk and certain additional risks. The Fund may be more sensitive to adverse economic, business or political developments if it invests a substantial portion of its assets in the bonds of similar projects (such as those relating to education, health care, housing, transportation, and utilities), industrial development bonds, or in particular types of municipal securities (such as general obligation bonds, private activity bonds and moral obligation bonds).&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Non-Investment Grade Fixed Income Securities Risk.&lt;/b&gt; &amp;nbsp;Non-investment grade fixed income securities and unrated securities of comparable credit quality (commonly known as &amp;#147;junk bonds&amp;#148;) are considered speculative and are subject to the increased risk of an issuer&amp;#146;s inability to meet principal and interest payment obligations. These securities may be subject to greater price volatility due to such factors as specific issuer developments, interest rate sensitivity, negative perceptions of the junk bond markets generally and less liquidity.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Short Position Risk.&lt;/b&gt; &amp;nbsp;The Fund may enter into a short position through a futures contract, an option or swap agreement or through short sales of any instrument that the Fund may purchase for investment. Taking short positions involves leverage of the Fund&amp;#146;s assets and presents various risks. If the price of the underlying instrument or market on which the Fund has taken a short position increases, then the Fund will incur a loss equal to the increase in price from the time that the short position was entered into plus any related interest payments or other fees. Taking short positions involves the risk that losses may be disproportionate, may exceed the amount invested and may be unlimited.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Sovereign Default Risk.&lt;/b&gt; &amp;nbsp;An issuer of non-U.S. sovereign debt held by the Fund 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;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;#147;Fannie Mae&amp;#148;), Federal Home Loan Mortgage Corporation (&amp;#147;Freddie Mac&amp;#148;) 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 their 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>

A high rate of portfolio turnover may result in increased transaction costs, including brokerage commissions, which must be borne by the Fund and its shareholders. These costs are not reflected in annual fund operating expenses or in the expense example above, but are reflected in the Fund&amp;#146;s performance.

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01May2014_30Apr2015S000035992_MemberService_Member">The Fund primarily seeks to achieve its investment objective by investing in a global portfolio of equity and fixed income asset classes. The Fund may invest in one or a combination of the following securities and instruments: pooled investment vehicles, including exchange-traded funds (&amp;#147;ETFs&amp;#148;) and other investment companies; equity securities and fixed income securities of U.S. and non-U.S. issuers; and derivatives that provide exposure to a broad spectrum of asset classes and geographic regions. Under normal market conditions, the Fund expects to invest at least 40% of its assets in equity investments and at least 20% of its assets in fixed income investments. The Investment Adviser makes investment decisions based upon its analysis of market factors around the world, and may allocate more of the Fund&amp;#146;s assets to investments with strong recent performance and allocate assets away from investments with poor recent performance. The percentage of the Fund&amp;#146;s portfolio exposed to any asset class or geographic region will vary from time to time as the weightings of the Fund change, and the Fund may not be invested in each asset class at all times. The Fund invests in at least three countries, including the United States, under normal market conditions. At times the Fund may be heavily invested in certain asset classes or geographic regions, depending on the asset allocation of the strategy. The Fund may invest without restriction as to issuer capitalization, currency, maturity or credit rating.&lt;br /&gt;&lt;br /&gt;As part of the Fund&amp;#146;s investment strategy, the Investment Adviser seeks to manage volatility and limit losses by allocating the Fund&amp;#146;s assets away from risky investments in distressed or volatile market environments. Volatility is a statistical measurement of the magnitude of up and down fluctuations in the value of a financial instrument or index. In distressed or volatile market environments, 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. While the Investment Adviser attempts to manage the Fund&amp;#146;s volatility, there can be no guarantee that the Fund will be successful.&lt;br /&gt;&lt;br /&gt;The Fund&amp;#146;s investments in derivatives may include: (i) futures contracts, including futures based on securities and/or indices; (ii) swaps, including interest rate, total return, variance, and/or index swaps, and swaps on futures contracts; (iii) options, including long and short positions in call options and put options on indices, or currencies, swaptions and options on futures contracts; and (iv) structured notes. The Fund may engage in forward foreign currency transactions for both investment and hedging purposes.&lt;br /&gt;&lt;br/&gt;THE FUND IS NON-DIVERSIFIED UNDER THE INVESTMENT COMPANY ACT OF 1940, AS AMENDED (&amp;#147;INVESTMENT COMPANY ACT&amp;#148;), AND MAY INVEST A LARGER PERCENTAGE OF ITS ASSETS IN FEWER ISSUERS THAN DIVERSIFIED MUTUAL FUNDS.&lt;br /&gt;&lt;br /&gt;The Fund&amp;#146;s blended benchmark is a composite of 60% Morgan Stanley Capital International (MSCI) World Index / 40% Barclays U.S. Aggregate Bond Index (the &amp;#147;60% MSCI World / 40% Barclays U.S. Aggregate Composite Index&amp;#148; or &amp;#147;Composite Index&amp;#148;), as discussed further under &amp;#147;Performance.&amp;#148;</rr:StrategyNarrativeTextBlock>

  <rr:RiskNarrativeTextBlock contextRef="Duration_01May2014_30Apr2015S000035992_MemberService_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;#147;FDIC&amp;#148;) 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. Investments in the Fund involve 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;  The Fund engages in over-the-counter (&amp;#147;OTC&amp;#148;) 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; 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;#146;s liquidity and cause significant deterioration in net asset value (&amp;#147;NAV&amp;#148;). To the extent that the Fund invests in non-investment grade fixed income securities, these risks may be more pronounced.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Derivatives Risk&lt;/b&gt;.&amp;nbsp; Loss may result from the Fund&amp;#146;s investments in options, futures, swaps, forwards, structured securities and other derivative instruments. These instruments may be illiquid, difficult to price and leveraged so that small changes in the value of the underlying instruments 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; By investing in pooled investment vehicles (including investment companies and ETFs), partnerships and real estate investment trusts (&amp;#147;REITs&amp;#148;) indirectly through the Fund, the investor will incur not only a proportionate share of the expenses of the pooled investment vehicles, partnerships and REITs held by the Fund (including operating costs and investment management fees), but also expenses of the Fund.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Foreign and Emerging Countries 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, sanctions, confiscations and other government restrictions by the United States and other governments, 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;Geographic Risk&lt;/b&gt;.&amp;nbsp; Concentration of the investments of the Fund in issuers located in a particular country or region will subject the Fund, to a greater extent than if investments were less concentrated, to the risks of adverse securities markets, exchange rates and social, political, regulatory or economic events which may occur in that country or region.&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 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;Large Shareholder Transactions Risk&lt;/b&gt;.&amp;nbsp; The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund&amp;#146;s NAV and liquidity. Similarly, large Fund share purchases may adversely affect the Fund&amp;#146;s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also increase transaction costs. In addition, a large redemption could result in the Fund&amp;#146;s current expenses being allocated over a smaller asset base, leading to an increase in the Fund&amp;#146;s expense ratio.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Leverage Risk&lt;/b&gt;.&amp;nbsp; The use of derivatives may result in leverage, which can magnify the effects of changes in the value of the Fund&amp;#146;s investments and make it more volatile. Borrowing and 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;#146;s investment portfolio may be subject.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Liquidity Risk&lt;/b&gt;.&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. Liquidity risk may be the result of, among other things, the reduced number and capacity of traditional market participants to make a market in fixed income securities or the lack of an active market. The potential for liquidity risk may be magnified by a rising interest rate environment or other circumstances where investor redemptions from fixed income mutual funds may be higher than normal, potentially causing increased supply in the market due to selling activity.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Management Risk&lt;/b&gt;.&amp;nbsp; A strategy used by the Investment Adviser may fail to produce the intended results.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Market Risk&lt;/b&gt;.&amp;nbsp; The 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;Mid-Cap and Small-Cap Risk.&lt;/b&gt;&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;NAV Risk.&lt;/b&gt;&amp;nbsp; The net asset value (&amp;#147;NAV&amp;#148;) of the Fund and the value of your investment may fluctuate.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Non-Diversification Risk&lt;/b&gt;.&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;Pooled Investments Risk.&lt;/b&gt;&amp;nbsp; By investing in pooled investment vehicles (including investment companies and ETFs), partnerships and REITs indirectly through the Fund, investors will incur a proportionate share of the expenses of the other pooled investment vehicles, partnerships and REITs held by the Fund (including operating costs and investment management fees), in addition to the fees and expenses regularly borne by the Fund. In addition, the Fund will be affected by the investment policies, practices and performance of such investments in direct proportion to the amount of assets the Fund invests therein.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Portfolio Turnover Rate Risk.&lt;/b&gt;&amp;nbsp; A high rate of portfolio turnover (100% or more) involves correspondingly greater expenses which must be borne by the Fund and its shareholders.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Sovereign Default Risk&lt;/b&gt;.&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;Stock Risk&lt;/b&gt;.&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.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Swaps Risk&lt;/b&gt;.&amp;nbsp; In a standard &amp;#147;swap&amp;#148; transaction, two parties agree to exchange the returns, differentials in rates of return or some other amount earned or realized on the &amp;#147;notional amount&amp;#148; 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;#146;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;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;#147;Fannie Mae&amp;#148;), Federal Home Loan Mortgage Corporation (&amp;#147;Freddie Mac&amp;#148;) 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 issuers of U.S. Government securities will not have the funds to meet their payment obligations in the future.</rr:RiskNarrativeTextBlock>

The Fund employs a &amp;#147;quantitative&amp;#148; 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;Large Shareholder Transactions Risk.&lt;/b&gt; &amp;nbsp;The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund.

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;#146; historical trends, and technical issues in the construction and implementation of the models (including, for example, data problems and/or software issues). There is no guarantee that the Investment Adviser&amp;#146;s use of these quantitative models will result in effective investment decisions for the Fund. Additionally, commonality of holdings across quantitative money managers may amplify losses.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Market Risk.&lt;/b&gt; &amp;nbsp;The 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;Mid-Cap and Small-Cap Risk.&lt;/b&gt; &amp;nbsp;Investments in mid-capitalization and small-capitalization companies involve greater risks than those associated with larger, more established companies.

The Composite Index is comprised of the Morgan Stanley Capital International (MSCI) World Index (60%) and the Barclays U.S. Aggregate Bond Index (40%). Through April 30, 2015, the Fund had been known as the Goldman Sachs Global Markets Navigator Fund, and its investment objective and certain of its strategies differed. Performance information prior to this date reflects the Fund&amp;#146;s former investment objective and strategies. In addition, as of April 30, 2015 the Fund&amp;#146;s benchmark index was changed from the Goldman Sachs Global Markets Navigator Index to the Composite Index. The Investment Adviser believes that the Composite Index is a more appropriate index against which to measure performance in light of the fact that the Fund will employ active investment management techniques, which may involve buying and selling securities and other instruments potentially based upon analysis of economic and market factors, rather than passively investing in such instruments in order to seek to track an index. The Fund&amp;#146;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. Had performance reflected all of those fees and expenses, performance would have been reduced.

The Fund&amp;#146;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. Had performance reflected all of those fees and expenses, performance would have been reduced.

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01May2014_30Apr2015S000009358_MemberInstitutional_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;#147;Net Assets&amp;#148;) in a diversified portfolio of equity investments in mid-cap issuers with public stock market capitalizations within the range of the market capitalization of companies constituting the Russell Midcap&lt;sup&gt;&amp;reg;&lt;/sup&gt; Value Index at the time of investment. As of April 1, 2015, the capitalization range of the Russell Midcap&lt;sup&gt;&amp;reg;&lt;/sup&gt; Value Index was between approximately $212 million and $34 billion. Although the Fund will invest primarily in publicly traded U.S. securities, including real estate investment trusts (&amp;#147;REITS&amp;#148;), it may invest in foreign securities, including securities of issuers in countries with emerging markets or economies (&amp;#147;emerging countries&amp;#148;) and securities quoted in foreign currencies.&lt;br /&gt;&lt;br /&gt;The Fund&amp;#146;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;#146;s outlook based on subsequent events, the Investment Adviser&amp;#146;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&lt;sup&gt;&amp;reg;&lt;/sup&gt; Value Index at the time of investment and in fixed income securities, such as government, corporate and bank debt obligations.&lt;br /&gt;&lt;br /&gt;The Fund&amp;#146;s benchmark index is the Russell Midcap&lt;sup&gt;&amp;reg;&lt;/sup&gt; Value Index.</rr:StrategyNarrativeTextBlock>

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01May2014_30Apr2015S000044541_MemberInstitutional_Member">The Portfolio seeks to achieve its investment objective by investing in a combination of underlying variable insurance funds and mutual funds that currently exist or that may become available for investment in the future for which Goldman Sachs Asset Management, L.P. (&amp;#147;GSAM&amp;#148; or the &amp;#147;Investment Adviser&amp;#148;) or an affiliate now or in the future acts as investment adviser or principal underwriter (the &amp;#147;Underlying Funds&amp;#148;). The Portfolio invests in Underlying Funds that pursue a variety of strategies and invest in a variety of asset classes. The Investment Adviser selects strategies and asset classes based on the desired risk profile and investment objective for the Portfolio. The Portfolio invests primarily in a portfolio of Underlying Funds that provide exposure to Liquid Alternatives Strategies and Real Assets (&amp;#147;Underlying Asset Classes and Strategies&amp;#148;). Liquid Alternatives Strategies generally include, but are not limited to, momentum or trend trading strategies (investment decisions based on trends in asset prices over time), hedge fund beta (long term total returns consistent with investment results that approximate the return and risk patterns of a diversified universe of hedge funds), managed risk investment strategies (which seek to manage extreme risk scenarios by implementing daily and monthly risk targets across a diversified mix of asset classes), emerging markets debt and unconstrained fixed income strategies (which have the ability to move across various fixed income sectors). Real Assets generally include, but are not limited to, commodities, global real estate securities, infrastructure and master limited partnerships (&amp;#147;MLPs&amp;#148;).&lt;br /&gt;&lt;br /&gt;Through its investments in Underlying Funds and/or unaffiliated exchange-traded funds (&amp;#147;ETFs&amp;#148;), the Portfolio may indirectly invest in the following to obtain exposure to Underlying Asset Classes and Strategies: (i) equity securities, including common and preferred stocks, real estate investment trusts (&amp;#147;REITs&amp;#148;), pooled investment vehicles (including other unaffiliated investment companies and ETFs) and partnership interests, including MLPs; (ii) fixed income and/or floating rate securities, including debt issued by corporations, debt issued by governments (including the U.S. and foreign governments), their agencies, instrumentalities, sponsored entities, and political subdivisions, covered bonds, notes, debentures, debt participations, convertible bonds, non-investment grade securities (commonly known as &amp;#147;junk bonds&amp;#148;), bank loans and other direct indebtedness; (iii) mortgage-backed and other mortgage-related securities, asset-backed securities, municipal securities, to be announced (&amp;#147;TBA&amp;#148;) securities and custodial receipts; (iv) currencies; and (v) restricted securities eligible for resale pursuant to Rule 144A under the Securities Act of 1933 (&amp;#147;144A Securities&amp;#148;). These investments may be publicly traded or privately issued or negotiated. The Portfolio may also invest directly in all of the above instruments. The Portfolio may invest without restriction as to issuer capitalization, country, currency, maturity or credit rating.&lt;br /&gt;&lt;br /&gt;The Portfolio and certain Underlying Funds may also invest in derivatives for both hedging and investment purposes. The Portfolio&amp;#146;s derivative exposure (which will primarily be obtained through its investments in the Underlying Funds) may include (i) futures contracts, including futures based on equity or fixed income securities and/or equity or fixed income indices, interest rate futures, currency futures and swap futures; (ii) swaps, including equity, currency, interest rate, total return, variance and credit default swaps and swaps on futures contracts; (iii) options, including long and short positions in call options and put options on indices, individual securities or currencies, swaptions and options on futures contracts; (iv) forward contracts, including forwards based on equity or fixed income securities and/or equity or fixed income indices, currency forwards, interest rate forwards, swap forwards and non-deliverable forwards; and (v) other instruments, including structured securities, credit linked notes, exchange-traded notes and contracts for differences (&amp;#147;CFDs&amp;#148;). The Portfolio&amp;#146;s direct derivatives investments are expected to consist primarily of futures, options on indices and currency forwards, which the Portfolio may use to gain exposure to certain markets or currencies.&lt;br /&gt;&lt;br /&gt;The Portfolio intends to invest no more than 20% of its total assets in Underlying Funds that are managed by an investment advisor other than GSAM or its affiliates. In managing the Portfolio, the Investment Adviser seeks to budget or allocate portfolio risk, as opposed to capital. The Investment Adviser adjusts the Portfolio&amp;#146;s risk exposures based on changes to its macro-economic views, changes to absolute and relative valuations across the Portfolio&amp;#146;s exposures, and changes in the risk characteristics of the Portfolio&amp;#146;s investments over time. The Investment Adviser may make short- to medium-term allocation adjustments to each Underlying Asset Class and Strategy and their constituents based on reasoned views of short- to medium-term market conditions with the goal of improving the Portfolio&amp;#146;s investments over time. The Investment Adviser may change the Portfolio&amp;#146;s allocation ranges, Underlying Asset Classes and Strategies and underlying investments from time to time at its discretion to incorporate its market views into the investment process and to react to changes in the macro-economic environment.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (&amp;#147;FDIC&amp;#148;) 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. Investments in the Fund involve 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; Different investment styles (e.g., &amp;#147;growth,&amp;#148; &amp;#147;value&amp;#148; or &amp;#147;quantitative&amp;#148;) 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;Large Shareholder Transactions Risk.&lt;/b&gt;&amp;nbsp; The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund&amp;#146;s net asset value (&amp;#147;NAV&amp;#148;) and liquidity. Similarly, large Fund share purchases may adversely affect the Fund&amp;#146;s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also increase transaction costs. In addition, a large redemption could result in the Fund&amp;#146;s current expenses being allocated over a smaller asset base, leading to an increase in the Fund&amp;#146;s expense ratio.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Market Risk.&lt;/b&gt;&amp;nbsp; The 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;Mid-Cap and Small-Cap Risk.&lt;/b&gt;&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;REIT Risk.&lt;/b&gt;&amp;nbsp; Risks associated with investments such as REITs in the real estate industry include, among others: possible declines in the value of real estate; risks related to general and local economic conditions; possible lack of availability of mortgage financing, variations in rental income, neighborhood values or the appeal of property to tenants; interest rates; overbuilding; extended vacancies of properties; increases in competition, property taxes and operating expenses; and changes in zoning laws. REITs whose underlying properties are concentrated in a particular industry or geographic region are subject to risks affecting such industries and regions. The securities of REITs involve greater risks than those associated with larger, more established companies and may be subject to more abrupt or erratic price movements because of interest rate changes, economic conditions and other factors. Securities of such issuers may lack sufficient market liquidity to enable the Fund to effect sales at an advantageous time or without a substantial drop in price.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Stock Risk.&lt;/b&gt;&amp;nbsp; Stock prices have historically risen and fallen in periodic cycles.

  <rr:RiskNarrativeTextBlock contextRef="Duration_01May2014_30Apr2015S000044541_MemberInstitutional_Member">&lt;b&gt;Loss of money is a risk of investing in the Portfolio. The investment program of the Portfolio is speculative, entails substantial risks and includes alternative investment techniques not employed by traditional mutual funds. The Portfolio should not be relied upon as a complete investment program. The Portfolio investment techniques (if they do not perform as designed) may increase the volatility of performance and the risk of investment loss, including the loss of the entire amount that is invested, and there can be no assurance that the investment objective of the Portfolio will be achieved. Moreover, certain investment  techniques which the Portfolio may employ in its investment program can substantially increase the adverse impact to which the Portfolio investments may be subject. There is no assurance that the investment processes of the Portfolio will be successful, that the techniques utilized therein will be implemented successfully or that they are adequate for their intended uses, or that the discretionary element of the investment processes of the Portfolio will be exercised in a manner that is successful or that is not adverse to the Portfolio. An investment in the Portfolio is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (&amp;#147;FDIC&amp;#148;) or any government agency. Investors should carefully consider these risks before investing. &lt;/b&gt;&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Derivatives Risk.&lt;/b&gt; &amp;nbsp;Loss may result from the Portfolio&amp;#146;s investments in futures, options on indices, currency forwards and other derivative instruments. These instruments may be illiquid, difficult to price and leveraged so that small changes in the value of the underlying instruments may produce disproportionate losses to the Portfolio. Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligations.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Expenses.&lt;/b&gt; &amp;nbsp;By investing in the Underlying Funds and unaffiliated ETFs indirectly through the Portfolio, the investor will incur not only a proportionate share of the expenses of the Underlying Funds and unaffiliated ETFs held by the Portfolio (including operating costs and investment management fees), but also expenses of the Portfolio.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Investing in the Underlying Funds and Unaffiliated ETFs.&lt;/b&gt; &amp;nbsp;The investments of the Portfolio are concentrated in the Underlying Funds, and the Portfolio&amp;#146;s investment performance is directly related to the investment performance of the Underlying Funds and unaffiliated ETFs it holds. The ability of the Portfolio to meet its investment objective is directly related to the ability of the Underlying Funds and unaffiliated ETFs to meet their objectives, as well as the allocation among those Underlying Funds and unaffiliated ETFs by the Investment Adviser.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Investments in Affiliated Underlying Funds.&lt;/b&gt; &amp;nbsp;The Investment Adviser will have the authority to select and substitute Underlying Funds. The Investment Adviser and/or its affiliates are compensated by the Portfolio and by the Underlying Funds for advisory and/or principal underwriting services provided. The Investment Adviser is subject to conflicts of interest in allocating Portfolio assets among the various Underlying Funds both because the fees payable to it and/or its affiliates by Underlying Funds differ and because the Investment Adviser and its affiliates are also responsible for managing the Underlying Funds. The portfolio managers may also be subject to conflicts of interest in allocating Portfolio assets among the various Underlying Funds because the Portfolio&amp;#146;s portfolio management team may also manage some of the Underlying Funds. The Trustees and officers of the Goldman Sachs Trust may also have conflicting interests in fulfilling their fiduciary duties to both the Portfolio and the Underlying Funds for which GSAM or its affiliates now or in the future serve as investment adviser or principal underwriter. In selecting actively managed Underlying Funds, the Investment Adviser generally expects to select affiliated investment companies without considering or canvassing the universe of unaffiliated investment companies available even though there may (or may not) be one or more unaffiliated investment company that may be a more appropriate addition to the Portfolio. To the extent that an investment in an affiliated investment company is not available, including as the result of capacity constraints, only then will the Investment Adviser consider unaffiliated investment companies.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Investments of the Underlying Funds.&lt;/b&gt; &amp;nbsp;Because the Portfolio invests in the Underlying Funds and unaffiliated ETFs, the Portfolio&amp;#146;s shareholders will be affected by the investment policies and practices of the Underlying Funds and unaffiliated ETFs in direct proportion to the amount of assets the Portfolio allocates to those Underlying Funds and unaffiliated ETFs. See the Principal Risks of the Underlying Funds below.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Large Shareholder Transactions Risk.&lt;/b&gt; &amp;nbsp;The Portfolio may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Portfolio. Such large shareholder redemptions may cause the Portfolio to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Portfolio&amp;#146;s NAV and liquidity. Similarly, large Portfolio share purchases may adversely affect the Portfolio&amp;#146;s performance to the extent that the Portfolio is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also increase transaction costs. In addition, a large redemption could result in the Portfolio&amp;#146;s current expenses being allocated over a smaller asset base, leading to an increase in the Portfolio&amp;#146;s expense ratio.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Temporary Investments.&lt;/b&gt; &amp;nbsp;Although the Portfolio normally seeks to invest primarily in the Underlying Funds, the Portfolio may invest a portion of its assets in high-quality, short-term debt obligations to maintain liquidity, to meet shareholder redemptions and for other short-term cash needs. For temporary defensive purposes during abnormal market or economic conditions, the Portfolio may invest without limitation in short-term obligations. When the Portfolio&amp;#146;s assets are invested in such investments, the Portfolio may not be achieving its investment objective.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Principal Risks of the Underlying Funds &lt;/b&gt;&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Absence of Regulation&lt;/b&gt;. &amp;nbsp;Certain Underlying Funds engage in over-the-counter (&amp;#147;OTC&amp;#148;) 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;Call/Prepayment Risk&lt;/b&gt;. &amp;nbsp;An issuer could exercise its right to pay principal on an obligation held by an Underlying Fund (such as a mortgage-backed security) earlier than expected. This may happen when there is a decline in interest rates, when credit spreads change, or when an issuer&amp;#146;s credit quality improves. Under these circumstances, the Underlying Fund may be unable to recoup all of its initial investment and will also suffer from having to reinvest in lower yielding securities.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Commodity Sector Risk&lt;/b&gt;. &amp;nbsp;Exposure to the commodities markets may subject an Underlying Fund to greater volatility than investments in more traditional securities. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. The prices of energy, industrial metals, precious metals, agriculture and livestock sector commodities may fluctuate widely due to factors such as changes in value, supply and demand and governmental regulatory policies. The commodity-linked investments in which an Underlying Fund&amp;#146;s subsidiary may enter into may involve counterparties in the financial services sector, and events affecting the financial services sector may cause the subsidiary&amp;#146;s, and therefore the Underlying Fund&amp;#146;s, share value to fluctuate.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Counterparty Risk&lt;/b&gt;. &amp;nbsp;Many of the protections afforded to participants on some organized exchanges, such as the security afforded by transacting through a clearinghouse, might not be available in connection with OTC transactions. Therefore, in those instances in which an Underlying Fund enters into OTC transactions, the Underlying Fund will be subject to the risk that its direct counterparty will not perform its obligations under the transactions and that the Underlying Fund will sustain losses.&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 an Underlying 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 an Underlying Fund&amp;#146;s liquidity and cause significant net asset value (&amp;#147;NAV&amp;#148;) deterioration. To the extent that an Underlying Fund invests in non-investment grade fixed income securities, these risks may be more pronounced.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Derivatives Risk.&lt;/b&gt; &amp;nbsp;Loss may result from an Underlying Fund&amp;#146;s investments in options, futures, forwards, swaps, structured securities and other derivative instruments. These instruments may be illiquid, difficult to price and leveraged so that small changes in the value of the underlying instruments may produce disproportionate losses to an Underlying 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;Distressed Debt Risk.&lt;/b&gt; &amp;nbsp;When an Underlying Fund invests in obligations of financially troubled companies (sometimes known as &amp;#147;distressed&amp;#148; securities), there exists the risk that the transaction involving such debt obligations will be unsuccessful, take considerable time or will result in a distribution of cash or a new security or obligation in exchange for the stressed and distressed debt obligations, the value of which may be less than the Underlying Fund&amp;#146;s purchase price of such debt obligations. Furthermore, if an anticipated transaction does not occur, the Underlying Fund may be required to sell its investment at a loss or hold its investment pending bankruptcy proceedings in the event the issuer files for bankruptcy.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Floating and Variable Rate Obligations Risks.&lt;/b&gt; &amp;nbsp;For floating and variable rate obligations, there may be a lag between an actual change in the underlying interest rate benchmark and the reset time for an interest payment of such an obligation, which could harm or benefit an Underlying Fund, depending on the interest rate environment or other circumstances. In a rising interest rate environment, for example, a floating or variable rate obligation that does not reset immediately would prevent an Underlying Fund from taking full advantage of rising interest rates in a timely manner. However, in a declining interest rate environment, an Underlying Fund may benefit from a lag due to an obligation&amp;#146;s interest rate payment not being immediately impacted by a decline in interest rates.&lt;br /&gt;&lt;br /&gt;Certain floating and variable rate obligations have an interest rate floor feature, which prevents the interest rate payable by the security from dropping below a specified level as compared to a reference interest rate (the &amp;#147;reference rate&amp;#148;), such as LIBOR. Such a floor protects an Underlying Fund from losses resulting from a decrease in the reference rate below the specified level. However, if the reference rate is below the floor, there will be a lag between a rise in the reference rate and a rise in the interest rate payable by the obligation, and an Underlying Fund may not benefit from increasing interest rates for a significant amount of time.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Foreign and Emerging Countries 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, less liquidity, greater volatility and less economic, political and social stability in the countries in which an Underlying Fund invests. Loss may also result from the imposition of exchange controls, sanctions, foreign taxes, confiscations, expropriations and other government restrictions by the United States and other governments, 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 an Underlying 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 an Underlying 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;Industry Concentration Risk&lt;/b&gt;. &amp;nbsp;The Goldman Sachs International Real Estate Securities Fund (&amp;#147;Underlying International Real Estate Securities Fund&amp;#148;) and Goldman Sachs Real Estate Securities Fund (&amp;#147;Underlying Real Estate Securities Fund&amp;#148;) concentrate their investments in the real estate industry, which has historically experienced substantial price volatility. This concentration subjects the Underlying International Real Estate Securities and Underlying Real Estate Securities Funds to greater risk of loss as a result of adverse economic, business or other developments than if their investments were diversified across different industries.&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 an Underlying 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;Investment Style Risk&lt;/b&gt;. &amp;nbsp;Different investment styles (e.g., &amp;#147;growth,&amp;#148; &amp;#147;value&amp;#148; or &amp;#147;quantitative&amp;#148;) tend to shift in and out of favor depending upon market and economic conditions and investor sentiment. An Underlying 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;Large Shareholder Transactions Risk.&lt;/b&gt; &amp;nbsp;An Underlying Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Underlying Fund. Such large shareholder redemptions may cause an Underlying Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Underlying Fund&amp;#146;s NAV and liquidity. Similarly, large Underlying Fund share purchases may adversely affect the Underlying Fund&amp;#146;s performance to the extent that the Underlying Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also increase transaction costs. In addition, a large redemption could result in the Underlying Fund&amp;#146;s current expenses being allocated over a smaller asset base, leading to an increase in the Underlying Fund&amp;#146;s expense ratio.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Leverage Risk&lt;/b&gt;. &amp;nbsp;Borrowing and the use of derivatives may result in leverage and may make an Underlying Fund more volatile. Borrowing and the use of leverage may cause an Underlying 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 an Underlying Fund can substantially increase the adverse impact to which the Underlying Fund&amp;#146;s investment portfolio may be subject.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Liquidity Risk.&lt;/b&gt; &amp;nbsp;An Underlying 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 an Underlying 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, an Underlying Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions. Liquidity risk may be the result of, among other things, the reduced number and capacity of traditional market participants to make a market in fixed income securities or the lack of an active market. The potential for liquidity risk may be magnified by a rising interest rate environment or other circumstances where investor redemptions from fixed income mutual funds may be higher than normal, potentially causing increased supply in the market due to selling activity.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Loan-Related Investments Risk.&lt;/b&gt; &amp;nbsp;In addition to risks generally associated with debt investments, loan-related investments such as loan participations and assignments are subject to other risks. Although a loan obligation may be fully collateralized at the time of acquisition, the collateral may decline in value, be relatively illiquid, or lose all or substantially all of its value subsequent to investment. Many loan investments are subject to legal or contractual restrictions on resale and may be relatively illiquid and difficult to value. There is less readily available, reliable information about most loan investments than is the case for many other types of securities. Substantial increases in interest rates may cause an increase in loan obligation defaults. With respect to loan participations, an Underlying Fund may not always have direct recourse against a borrower if the borrower fails to pay scheduled principal and/or interest; may be subject to greater delays, expenses and risks than if the Underlying Fund had purchased a direct obligation of the borrower; and may be regarded as the creditor of the agent lender (rather than the borrower), subjecting the Underlying Fund to the creditworthiness of that lender as well. The market for loan obligations may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods. Because transactions in many loans are subject to extended trade settlement periods, the Underlying Fund may not receive the proceeds from the sale of a loan for a period after the sale. As a result, sale proceeds related to the sale of loans may not be available to make additional investments or to meet the Underlying Fund&amp;#146;s redemption obligations for a period after the sale of the loans, and, as a result, the Underlying Fund may have to sell other investments or engage in borrowing transactions, such as borrowing from its credit facility, if necessary to raise cash to meet its obligations.&lt;br /&gt;&lt;br /&gt;Senior loans hold the most senior position in the capital structure of a business entity, and are typically secured with specific collateral, but are nevertheless usually rated below investment grade. Because second lien loans are subordinated or unsecured and thus lower in priority of payment to senior loans, they are subject to the additional risk that the cash flow of the borrower and property securing the loan or debt, if any, may be insufficient to meet scheduled payments after giving effect to the senior secured obligations of the borrower. Second lien loans generally have greater price volatility than senior loans and may be less liquid.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Management Risk.  &lt;/b&gt; &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 with respect to certain of the Underlying Funds 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;#146; historical trends, and technical issues in the construction and implementation of the models (including, for example, data problems and/or software issues). There is no guarantee that the Investment Adviser&amp;#146;s use of these quantitative models will result in effective investment decisions for an Underlying Fund. Additionally, commonality of holdings across quantitative money managers may amplify losses.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Market Risk.&lt;/b&gt; &amp;nbsp;The market value of the securities in which an Underlying 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;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;Mortgage-Backed and Other Asset-Backed Securities Risk.  &lt;/b&gt; &amp;nbsp;Mortgage-related and other asset-backed securities are subject to certain additional risks, including &amp;#147;extension risk&amp;#148; (i.e., in periods of rising interest rates, issuers may pay principal later than expected) and &amp;#147;prepayment risk&amp;#148; (i.e., in periods of declining interest rates, issuers may pay principal more quickly than expected, causing an Underlying 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;Municipal Securities Risk.&lt;/b&gt; &amp;nbsp;Municipal securities are subject to call/prepayment risk, credit/default risk, interest rate risk and certain additional risks. An Underlying Fund may be more sensitive to adverse economic, business or political developments if it invests a substantial portion of its assets in the bonds of similar projects (such as those relating to education, health care, housing, transportation, and utilities), industrial development bonds, or in particular types of municipal securities (such as general obligation bonds, private activity bonds and moral obligation bonds).&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Non-Diversification Risk.&lt;/b&gt; &amp;nbsp;Certain of the Underlying Funds are non-diversified, meaning that they are permitted to invest a larger percentage of their assets in fewer issuers than diversified mutual funds. Thus, an Underlying 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;Non-Hedging Foreign Currency Trading Risk&lt;/b&gt;. &amp;nbsp;Certain Underlying Funds may engage in forward foreign currency transactions for investment purposes. An Underlying Fund&amp;#146;s investment adviser may purchase or sell foreign currencies through the use of forward contracts based on the investment adviser&amp;#146;s judgment regarding the direction of the market for a particular foreign currency or currencies. In pursuing this strategy, the Underlying Fund&amp;#146;s investment adviser seeks to profit from anticipated movements in currency rates by establishing &amp;#147;long&amp;#148; and/or &amp;#147;short&amp;#148; positions in forward contracts on various foreign currencies. Foreign exchange rates can be extremely volatile and a variance in the degree of volatility of the market or in the direction of the market from the investment adviser&amp;#146;s expectations may produce significant losses to the Underlying Fund. Some of these transactions may also be subject to interest rate risk.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Non-Investment Grade Fixed Income Securities Risk.&lt;/b&gt; &amp;nbsp;Non-investment grade fixed income securities and unrated securities of comparable credit quality (commonly known as &amp;#147;junk bonds&amp;#148;) are considered speculative and are subject to the increased risk of an issuer&amp;#146;s inability to meet principal and interest payment obligations. These securities may be subject to greater price volatility due to such factors as specific issuer developments, interest rate sensitivity, negative perceptions of the junk bond markets generally and less liquidity.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Portfolio Turnover Rate Risk.&lt;/b&gt; &amp;nbsp;A high rate of portfolio turnover (100% or more) involves correspondingly greater expenses which must be borne by an Underlying Fund and its shareholders (including the Portfolio), and is also likely to result in short-term capital gains taxable to shareholders of the Underlying Fund.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Real Estate Industry Risk&lt;/b&gt;. &amp;nbsp;Risks associated with investments in the real estate industry include, among others: possible declines in the value of real estate; risks related to general and local economic conditions; possible lack of availability of mortgage financing, variations in rental income, neighborhood values or the appeal of property to tenants; interest rates; overbuilding; extended vacancies of properties; increases in competition, property taxes and operating expenses; and changes in zoning laws. The real estate industry is particularly sensitive to economic downturns. The values of securities of companies in the real estate industry may go through cycles of relative underperformance and out-performance in comparison to equity securities markets in general.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;REIT Risk&lt;/b&gt;. &amp;nbsp;REITs whose underlying properties are concentrated in a particular industry or geographic region are subject to risks affecting such industries and regions. The securities of REITs involve greater risks than those associated with larger, more established companies and may be subject to more abrupt or erratic price movements because of interest rate changes, economic conditions and other factors. Securities of such issuers may lack sufficient market liquidity to enable an Underlying Fund to effect sales at an advantageous time or without a substantial drop in price.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Short Position Risk&lt;/b&gt;. &amp;nbsp;An Underlying Fund may enter into a short position through a futures contract, an option or swap agreement or through short sales of any instrument that the Underlying Fund may purchase for investment. Taking short positions involves leverage of the Underlying Fund&amp;#146;s assets and presents various risks. If the value of the underlying instrument or market in which the Underlying Fund has taken a short position increases, then the Underlying Fund will incur a loss equal to the increase in value from the time that the short position was entered into plus any related interest payments or other fees. Taking short positions involves the risk that losses may be disproportionate, may exceed the amount invested and may be unlimited.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Sovereign Default Risk.&lt;/b&gt; &amp;nbsp;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. 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;Special Situation Investments Risk.&lt;/b&gt; &amp;nbsp;An Underlying Fund may make investments in event-driven situations such as recapitalizations, financings, corporate and financial restructurings, acquisitions, divestitures, reorganizations or other situations in public or private companies that may provide the Underlying Fund with an opportunity to provide debt and/or equity financing, typically on a negotiated basis. The Investment Adviser of the Underlying Fund will seek special situation investment opportunities with limited downside risk relative to their potential upside. These investments are complicated and an incorrect assessment of the downside risk associated with an investment could result in significant losses to the Underlying Fund.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Stock Risk.&lt;/b&gt; &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.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Subsidiary Risk&lt;/b&gt;. &amp;nbsp;The subsidiaries of certain Underlying Funds are not registered under the Investment Company Act of 1940, as amended (&amp;#147;Investment Company Act&amp;#148;) and are not subject to all the investor protections of the Investment Company Act. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of an Underlying Fund and/or its subsidiary to operate as intended and could adversely affect the Underlying Fund.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Swaps Risk&lt;/b&gt;. &amp;nbsp;In a standard &amp;#147;swap&amp;#148; transaction, two parties agree to exchange the returns, differentials in rates of return or some other amount earned or realized on the &amp;#147;notional amount&amp;#148; 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;#146;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 an Underlying 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;Tax Risk&lt;/b&gt;. &amp;nbsp;Certain Underlying Funds will seek to gain exposure to the commodity markets primarily through investments in a subsidiary and/or commodity index-linked structured notes. Historically, the Internal Revenue Service (&amp;#147;IRS&amp;#148;) has issued private letter rulings in which the IRS specifically concluded that income and gains from investments in commodity index-linked structured notes or a wholly-owned foreign subsidiary that invests in commodity-linked instruments are &amp;#147;qualifying income&amp;#148; for purposes of compliance with Subchapter M of the Internal Revenue Code of 1986, as amended (the &amp;#147;Code&amp;#148;). However, while certain Underlying Funds have received such a private letter ruling, others have not, and those that have not are unable to rely on private letter rulings issued to other taxpayers. Additionally, the IRS has suspended the granting of such private letter rulings, pending review of its position on this matter. The tax treatment of certain Underlying Funds&amp;#146; investments in a subsidiary or commodity index-linked structured notes may be adversely affected by future legislation, Treasury Regulations and/or guidance issued by the IRS (which may be retroactive) that could affect whether income derived from such investments is &amp;#147;qualifying income&amp;#148; under Subchapter M of Code, or otherwise affect the character, timing and/or amount of the Underlying Funds&amp;#146; taxable income or any gains and distributions made by the Underlying Funds. In connection with investments in a subsidiary and/or commodity index-linked structured notes, certain Underlying Funds have obtained or may seek to obtain an opinion of counsel that their income from such investments should constitute &amp;#147;qualifying income.&amp;#148; However, no assurances can be provided that the IRS would not be able to successfully assert that the Underlying Funds&amp;#146; income from such investments was not &amp;#147;qualifying income&amp;#148;, in which case an Underlying Fund would fail to qualify as a regulated investment company (RIC) under Subchapter M of the Code if over 10% of its gross income was derived from these investments. If an Underlying Fund failed to qualify as a RIC, it would be subject to federal and state income tax on all of its taxable income at regular corporate tax rates with no deduction for any distributions paid to shareholders, which would significantly adversely affect the returns to, and could cause substantial losses for, Underlying Fund shareholders.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Treasury Inflation Protected Securities Risk&lt;/b&gt;. &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;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 those agencies, instrumentalities and sponsored enterprises, including those issued by the Federal National Mortgage Association (&amp;#147;Fannie Mae&amp;#148;), Federal Home Loan Mortgage Corporation (&amp;#147;Freddie Mac&amp;#148;) 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 an Underlying 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.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Further Information on Investment Objectives, Strategies and Risks of the Underlying Funds.&lt;/b&gt; &amp;nbsp;A concise description of the investment objectives, practices and risks of each of the Underlying Funds that are currently expected to be used for investment by the Portfolio as of the date of this Prospectus is provided beginning on page 14 of this Prospectus.</rr:RiskNarrativeTextBlock>

The Fund seeks to achieve its investment objective by investing, under normal circumstances, in approximately 60-80 companies that are considered by the Investment Adviser to be 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;#147;emerging countries&amp;#148;) and securities quoted in foreign currencies. The Fund may also invest in privately held companies and companies that only recently began to trade publicly.&lt;br /&gt;&lt;br /&gt;The Fund&amp;#146;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;#146;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;#146;s definition of a mid cap company. In addition, the Investment Adviser may sell a position in order to meet shareholder redemptions.&lt;br /&gt;&lt;br /&gt;The Fund&amp;#146;s benchmark index is the Russell Midcap&lt;sup&gt;&amp;reg;&lt;/sup&gt; Growth Index.</rr:StrategyNarrativeTextBlock>

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (&amp;#147;FDIC&amp;#148;) 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. Investments in the Fund involve 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; Different investment styles (e.g., &amp;#147;growth,&amp;#148; &amp;#147;value&amp;#148; or &amp;#147;quantitative&amp;#148;) 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;Large Shareholder Transactions Risk.&lt;/b&gt;&amp;nbsp; The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund&amp;#146;s net asset value (&amp;#147;NAV&amp;#148;) and liquidity. Similarly, large Fund share purchases may adversely affect the Fund&amp;#146;s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also increase transaction costs. In addition, a large redemption could result in the Fund&amp;#146;s current expenses being allocated over a smaller asset base, leading to an increase in the Fund&amp;#146;s expense ratio.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Market Risk.&lt;/b&gt;&amp;nbsp; The value of the securities 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; 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; 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;#146;s investments are selected using fundamental research and a variety of quantitative techniques based on certain investment themes, including, among others, Momentum, Valuation and Profitability. 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 Valuation theme attempts to capture potential mispricings of securities, typically by comparing a measure of the company&amp;#146;s intrinsic value to its market value. The Profitability theme seeks to assess whether a company is earning more than its cost of capital. 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;#146;s proprietary research.&lt;br /&gt;&lt;br /&gt;The Fund maintains risk, style, and capitalization characteristics similar to the S&amp;amp;P 500&lt;sup&gt;&amp;reg;&lt;/sup&gt; Index, which is an index of large-cap stocks designed to reflect a broad representation of the U.S. economy. As of March 31, 2015, the market capitalization range for the S&amp;amp;P 500&lt;sup&gt;&amp;reg;&lt;/sup&gt; Index was between approximately $3.26 billion and $724.77 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&gt;&amp;reg;&lt;/sup&gt; Index capitalization range.&lt;br /&gt;The Fund may also invest in fixed income securities that are limited to securities that are considered to be cash equivalents.&lt;br /&gt;&lt;br /&gt;The Fund&amp;#146;s benchmark index is the S&amp;amp;P 500&lt;sup&gt;&amp;reg;&lt;/sup&gt; Index.</rr:StrategyNarrativeTextBlock>

A high rate of portfolio turnover may result in increased transaction costs, including brokerage commissions, which must be borne by the Fund and its shareholders. These costs are not reflected in annual fund operating expenses or in the expense example above, but are reflected in the Fund&amp;#146;s performance.

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01May2014_30Apr2015S000009352_MemberService_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;#147;Net Assets&amp;#148;) 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 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;#146;s investments are selected using fundamental research and a variety of quantitative techniques based on certain investment themes, including, among others, Momentum, Valuation and Profitability. 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 Valuation theme attempts to capture potential mispricings of securities, typically by comparing a measure of the company&amp;#146;s intrinsic value to its market value. The Profitability theme seeks to assess whether a company is earning more than its cost of capital. 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;#146;s proprietary research.&lt;br /&gt;&lt;br /&gt;The Fund maintains risk, style, and capitalization characteristics similar to the S&amp;amp;P 500&lt;sup&gt;&amp;reg;&lt;/sup&gt; Index, which is an index of large-cap stocks designed to reflect a broad representation of the U.S. economy. As of March 31, 2015, the market capitalization range for the S&amp;amp;P 500&lt;sup&gt;&amp;reg;&lt;/sup&gt; Index was between approximately $3.26 billion and $724.77 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&gt;&amp;reg;&lt;/sup&gt; Index capitalization range.&lt;br /&gt;&lt;br /&gt;The Fund may also invest in fixed income securities that are limited to securities that are considered to be cash equivalents.&lt;br /&gt;&lt;br /&gt;The Fund&amp;#146;s benchmark index is the S&amp;amp;P 500&lt;sup&gt;&amp;reg;&lt;/sup&gt; Index.</rr:StrategyNarrativeTextBlock>

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (&amp;#147;FDIC&amp;#148;) 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. Investments in the Fund involve 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;Different investment styles (e.g., &amp;#147;growth,&amp;#148; &amp;#147;value&amp;#148; or &amp;#147;quantitative&amp;#148;) tend to shift in and out of favor depending upon market and economic conditions and investor sentiment. The Fund employs a &amp;#147;quantitative&amp;#148; 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;Large Shareholder Transactions Risk.  &lt;/b&gt; &amp;nbsp;The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund&amp;#146;s net asset value (&amp;#147;NAV&amp;#148;) and liquidity. Similarly, large Fund share purchases may adversely affect the Fund&amp;#146;s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also increase transaction costs. In addition, a large redemption could result in the Fund&amp;#146;s current expenses being allocated over a smaller asset base, leading to an increase in the Fund&amp;#146;s expense ratio.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Management Risk.&lt;/b&gt; &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;#146; historical trends, and technical issues in the construction and implementation of the models (including, for example, data problems and/or software issues). There is no guarantee that the Investment Adviser&amp;#146;s use of these quantitative models will result in effective investment decisions for the Fund. Additionally, commonality of holdings across quantitative money managers may amplify losses.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Market Risk.&lt;/b&gt; &amp;nbsp;The 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;Portfolio Turnover Rate Risk.&lt;/b&gt; &amp;nbsp;A high rate of portfolio turnover (100% or more) involves correspondingly greater expenses which must be borne by the Fund and its shareholders.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Stock Risk.&lt;/b&gt; &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>

(&amp;#147;GSAM&amp;#148; or the &amp;#147;Investment Adviser&amp;#148;) or an affiliate now or in the future acts as investment adviser or principal underwriter (the &amp;#147;Underlying Funds&amp;#148;). The Portfolio invests in Underlying Funds that pursue a variety of strategies and invest in a variety of asset classes. The Investment Adviser selects strategies and asset classes based on the desired risk profile and investment objective for the Portfolio. The Portfolio invests primarily in a portfolio of Underlying Funds that provide exposure to Liquid Alternatives Strategies and Real Assets (&amp;#147;Underlying Asset Classes and Strategies&amp;#148;). Liquid Alternatives Strategies generally include, but are not limited to, momentum or trend trading strategies (investment decisions based on trends in asset prices over time), hedge fund beta (long term total returns consistent with investment results that approximate the return and risk patterns of a diversified universe of hedge funds), managed risk investment strategies (which seek to manage extreme risk scenarios by implementing daily and monthly risk targets across a diversified mix of asset classes), emerging markets debt and unconstrained fixed income strategies (which have the ability to move across various fixed income sectors). Real Assets generally include, but are not limited to, commodities, global real estate securities, infrastructure and master limited partnerships (&amp;#147;MLPs&amp;#148;).&lt;br /&gt;&lt;br /&gt;Through its investments in Underlying Funds and/or unaffiliated exchange-traded funds (&amp;#147;ETFs&amp;#148;), the Portfolio may indirectly invest in the following to obtain exposure to Underlying Asset Classes and Strategies: (i) equity securities, including common and preferred stocks, real estate investment trusts (&amp;#147;REITs&amp;#148;), pooled investment vehicles (including other unaffiliated investment companies and ETFs) and partnership interests, including MLPs; (ii) fixed income and/or floating rate securities, including debt issued by corporations, debt issued by governments (including the U.S. and foreign governments), their agencies, instrumentalities, sponsored entities, and political subdivisions, covered bonds, notes, debentures, debt participations, convertible bonds, non-investment grade securities (commonly known as &amp;#147;junk bonds&amp;#148;), bank loans and other direct indebtedness; (iii) mortgage-backed and other mortgage-related securities, asset-backed securities, municipal securities, to be announced (&amp;#147;TBA&amp;#148;) securities and custodial receipts; (iv) currencies; and (v) restricted securities eligible for resale pursuant to Rule 144A under the Securities Act of 1933 (&amp;#147;144A Securities&amp;#148;). These investments may be publicly traded or privately issued or negotiated. The Portfolio may also invest directly in all of the above instruments. The Portfolio may invest without restriction as to issuer capitalization, country, currency, maturity or credit rating.&lt;br /&gt;&lt;br /&gt;The Portfolio and certain Underlying Funds may also invest in derivatives for both hedging and investment purposes. The Portfolio&amp;#146;s derivative exposure (which will primarily be obtained through its investments in the Underlying Funds) may include (i) futures contracts, including futures based on equity or fixed income securities and/or equity or fixed income indices, interest rate futures, currency futures and swap futures; (ii) swaps, including equity, currency, interest rate, total return, variance and credit default swaps and swaps on futures contracts; (iii) options, including long and short positions in call options and put options on indices, individual securities or currencies, swaptions and options on futures contracts; (iv) forward contracts, including forwards based on equity or fixed income securities and/or equity or fixed income indices, currency forwards, interest rate forwards, swap forwards and non-deliverable forwards; and (v) other instruments, including structured securities, credit linked notes, exchange-traded notes and contracts for differences (&amp;#147;CFDs&amp;#148;). The Portfolio&amp;#146;s direct derivatives investments are expected to consist primarily of futures, options on indices and currency forwards, which the Portfolio may use to gain exposure to certain markets or currencies.&lt;br /&gt;&lt;br /&gt;The Portfolio intends to invest no more than 20% of its total assets in Underlying Funds that are managed by an investment advisor other than GSAM or its affiliates. In managing the Portfolio, the Investment Adviser seeks to budget or allocate portfolio risk, as opposed to capital. The Investment Adviser adjusts the Portfolio&amp;#146;s risk exposures based on changes to its macro-economic views, changes to absolute and relative valuations across the Portfolio&amp;#146;s exposures, and changes in the risk characteristics of the Portfolio&amp;#146;s investments over time. The Investment Adviser may make short- to medium-term allocation adjustments to each Underlying Asset Class and Strategy and their constituents based on reasoned views of short- to medium-term market conditions with the goal of improving the Portfolio&amp;#146;s investments over time. The Investment Adviser may change the Portfolio&amp;#146;s allocation ranges, Underlying Asset Classes and Strategies and underlying investments from time to time at its discretion to incorporate its market views into the investment process and to react to changes in the macro-economic environment.

There is no assurance that the investment processes of the Portfolio will be successful, that the techniques utilized therein will be implemented successfully or that they are adequate for their intended uses, or that the discretionary element of the investment processes of the Portfolio will be exercised in a manner that is successful or that is not adverse to the Portfolio. An investment in the Portfolio is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (&amp;#147;FDIC&amp;#148;) or any government agency. Investors should carefully consider these risks before investing.&lt;/b&gt;&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Derivatives Risk. &lt;/b&gt;&amp;nbsp;Loss may result from the Portfolio&amp;#146;s investments in futures, options on indices, currency forwards and other derivative instruments. These instruments may be illiquid, difficult to price and leveraged so that small changes in the value of the underlying instruments may produce disproportionate losses to the Portfolio. Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligations.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Expenses. &lt;/b&gt;&amp;nbsp;By investing in the Underlying Funds and unaffiliated ETFs indirectly through the Portfolio, the investor will incur not only a proportionate share of the expenses of the Underlying Funds and unaffiliated ETFs held by the Portfolio (including operating costs and investment management fees), but also expenses of the Portfolio.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Investing in the Underlying Funds and Unaffiliated ETFs. &lt;/b&gt;&amp;nbsp;The investments of the Portfolio are concentrated in the Underlying Funds, and the Portfolio&amp;#146;s investment performance is directly related to the investment performance of the Underlying Funds and unaffiliated ETFs it holds. The ability of the Portfolio to meet its investment objective is directly related to the ability of the Underlying Funds and unaffiliated ETFs to meet their objectives, as well as the allocation among those Underlying Funds and unaffiliated ETFs by the Investment Adviser.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Investments in Affiliated Underlying Funds. &lt;/b&gt;&amp;nbsp;The Investment Adviser will have the authority to select and substitute Underlying Funds. The Investment Adviser and/or its affiliates are compensated by the Portfolio and by the Underlying Funds for advisory and/or principal underwriting services provided. The Investment Adviser is subject to conflicts of interest in allocating Portfolio assets among the various Underlying Funds both because the fees payable to it and/or its affiliates by Underlying Funds differ and because the Investment Adviser and its affiliates are also responsible for managing the Underlying Funds. The portfolio managers may also be subject to conflicts of interest in allocating Portfolio assets among the various Underlying Funds because the Portfolio&amp;#146;s portfolio management team may also manage some of the Underlying Funds. The Trustees and officers of the Goldman Sachs Trust may also have conflicting interests in fulfilling their fiduciary duties to both the Portfolio and the Underlying Funds for which GSAM or its affiliates now or in the future serve as investment adviser or principal underwriter. In selecting actively managed Underlying Funds, the Investment Adviser generally expects to select affiliated investment companies without considering or canvassing the universe of unaffiliated investment companies available even though there may (or may not) be one or more unaffiliated investment company that may be a more appropriate addition to the Portfolio. To the extent that an investment in an affiliated investment company is not available, including as the result of capacity constraints, only then will the Investment Adviser consider unaffiliated investment companies.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Investments of the Underlying Funds. &lt;/b&gt;&amp;nbsp;Because the Portfolio invests in the Underlying Funds and unaffiliated ETFs, the Portfolio&amp;#146;s shareholders will be affected by the investment policies and practices of the Underlying Funds and unaffiliated ETFs in direct proportion to the amount of assets the Portfolio allocates to those Underlying Funds and unaffiliated ETFs. See the Principal Risks of the Underlying Funds below.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Large Shareholder Transactions Risk. &lt;/b&gt;&amp;nbsp;The Portfolio may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Portfolio. Such large shareholder redemptions may cause the Portfolio to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Portfolio&amp;#146;s NAV and liquidity. Similarly, large Portfolio share purchases may adversely affect the Portfolio&amp;#146;s performance to the extent that the Portfolio is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also increase transaction costs. In addition, a large redemption could result in the Portfolio&amp;#146;s current expenses being allocated over a smaller asset base, leading to an increase in the Portfolio&amp;#146;s expense ratio.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Temporary Investments. &lt;/b&gt;&amp;nbsp;Although the Portfolio normally seeks to invest primarily in the Underlying Funds, the Portfolio may invest a portion of its assets in high-quality, short-term debt obligations to maintain liquidity, to meet shareholder redemptions and for other short-term cash needs. For temporary defensive purposes during abnormal market or economic conditions, the Portfolio may invest without limitation in short-term obligations. When the Portfolio&amp;#146;s assets are invested in such investments, the Portfolio may not be achieving its investment objective.&lt;br /&gt;&lt;br/&gt;&lt;b&gt;Principal Risks of the Underlying Funds &lt;/b&gt;&lt;br/&gt;&lt;br /&gt;&lt;b&gt;Absence of Regulation&lt;/b&gt;.&amp;nbsp; Certain Underlying Funds engage in over-the-counter (&amp;#147;OTC&amp;#148;) 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;Call/Prepayment Risk&lt;/b&gt;.&amp;nbsp;  An issuer could exercise its right to pay principal on an obligation held by an Underlying Fund (such as a mortgage-backed security) earlier than expected. This may happen when there is a decline in interest rates, when credit spreads change, or when an issuer&amp;#146;s credit quality improves. Under these circumstances, the Underlying Fund may be unable to recoup all of its initial investment and will also suffer from having to reinvest in lower yielding securities.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Commodity Sector Risk&lt;/b&gt;.&amp;nbsp;  Exposure to the commodities markets may subject an Underlying Fund to greater volatility than investments in more traditional securities. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. The prices of energy, industrial metals, precious metals, agriculture and livestock sector commodities may fluctuate widely due to factors such as changes in value, supply and demand and governmental regulatory policies. The commodity-linked investments in which an Underlying Fund&amp;#146;s subsidiary may enter into may involve counterparties in the financial services sector, and events affecting the financial services sector may cause the subsidiary&amp;#146;s, and therefore the Underlying Fund&amp;#146;s, share value to fluctuate.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Counterparty Risk&lt;/b&gt;.&amp;nbsp;  Many of the protections afforded to participants on some organized exchanges, such as the security afforded by transacting through a clearinghouse, might not be available in connection with OTC transactions. Therefore, in those instances in which an Underlying Fund enters into OTC transactions, the Underlying Fund will be subject to the risk that its direct counterparty will not perform its obligations under the transactions and that the Underlying Fund will sustain losses.&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 an Underlying 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 an Underlying Fund&amp;#146;s liquidity and cause significant net asset value (&amp;#147;NAV&amp;#148;) deterioration. To the extent that an Underlying Fund invests in non-investment grade fixed income securities, these risks may be more pronounced.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Derivatives Risk. &lt;/b&gt;&amp;nbsp;Loss may result from an Underlying Fund&amp;#146;s investments in options, futures, forwards, swaps, structured securities and other derivative instruments. These instruments may be illiquid, difficult to price and leveraged so that small changes in the value of the underlying instruments may produce disproportionate losses to an Underlying 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;Distressed Debt Risk&lt;/b&gt;.&amp;nbsp;  When an Underlying Fund invests in obligations of financially troubled companies (sometimes known as &amp;#147;distressed&amp;#148; securities), there exists the risk that the transaction involving such debt obligations will be unsuccessful, take considerable time or will result in a distribution of cash or a new security or obligation in exchange for the stressed and distressed debt obligations, the value of which may be less than the Underlying Fund&amp;#146;s purchase price of such debt obligations. Furthermore, if an anticipated transaction does not occur, the Underlying Fund may be required to sell its investment at a loss or hold its investment pending bankruptcy proceedings in the event the issuer files for bankruptcy.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Floating and Variable Rate Obligations Risks. &lt;/b&gt;&amp;nbsp;For floating and variable rate obligations, there may be a lag between an actual change in the underlying interest rate benchmark and the reset time for an interest payment of such an obligation, which could harm or benefit an Underlying Fund, depending on the interest rate environment or other circumstances. In a rising interest rate environment, for example, a floating or variable rate obligation that does not reset immediately would prevent an Underlying Fund from taking full advantage of rising interest rates in a timely manner. However, in a declining interest rate environment, an Underlying Fund may benefit from a lag due to an obligation&amp;#146;s interest rate payment not being immediately impacted by a decline in interest rates.&lt;br /&gt;&lt;br /&gt;Certain floating and variable rate obligations have an interest rate floor feature, which prevents the interest rate payable by the security from dropping below a specified level as compared to a reference interest rate (the &amp;#147;reference rate&amp;#148;), such as LIBOR. Such a floor protects an Underlying Fund from losses resulting from a decrease in the reference rate below the specified level. However, if the reference rate is below the floor, there will be a lag between a rise in the reference rate and a rise in the interest rate payable by the obligation, and an Underlying Fund may not benefit from increasing interest rates for a significant amount of time.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Foreign and Emerging Countries 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, less liquidity, greater volatility and less economic, political and social stability in the countries in which an Underlying Fund invests. Loss may also result from the imposition of exchange controls, sanctions, foreign taxes, confiscations, expropriations and other government restrictions by the United States and other governments, 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 an Underlying 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 an Underlying 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;Industry Concentration Risk&lt;/b&gt;.&amp;nbsp;  The Goldman Sachs International Real Estate Securities Fund (&amp;#147;Underlying International Real Estate Securities Fund&amp;#148;) and Goldman Sachs Real Estate Securities Fund (&amp;#147;Underlying Real Estate Securities Fund&amp;#148;) concentrate their investments in the real estate industry, which has historically experienced substantial price volatility. This concentration subjects the Underlying International Real Estate Securities and Underlying Real Estate Securities Funds to greater risk of loss as a result of adverse economic, business or other developments than if their investments were diversified across different industries.&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 an Underlying 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;Investment Style Risk&lt;/b&gt;.&amp;nbsp;  Different investment styles (e.g., &amp;#147;growth,&amp;#148; &amp;#147;value&amp;#148; or &amp;#147;quantitative&amp;#148;) tend to shift in and out of favor depending upon market and economic conditions and investor sentiment. An Underlying 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;Large Shareholder Transactions Risk. &lt;/b&gt;&amp;nbsp;An Underlying Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Underlying Fund. Such large shareholder redemptions may cause an Underlying Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Underlying Fund&amp;#146;s NAV and liquidity. Similarly, large Underlying Fund share purchases may adversely affect the Underlying Fund&amp;#146;s performance to the extent that the Underlying Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also increase transaction costs. In addition, a large redemption could result in the Underlying Fund&amp;#146;s current expenses being allocated over a smaller asset base, leading to an increase in the Underlying Fund&amp;#146;s expense ratio.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Leverage Risk&lt;/b&gt;.&amp;nbsp;  Borrowing and the use of derivatives may result in leverage and may make an Underlying Fund more volatile. Borrowing and the use of leverage may cause an Underlying 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 an Underlying Fund can substantially increase the adverse impact to which the Underlying Fund&amp;#146;s investment portfolio may be subject.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Liquidity Risk. &lt;/b&gt;&amp;nbsp;An Underlying 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 an Underlying 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, an Underlying Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions. Liquidity risk may be the result of, among other things, the reduced number and capacity of traditional market participants to make a market in fixed income securities or the lack of an active market. The potential for liquidity risk may be magnified by a rising interest rate environment or other circumstances where investor redemptions from fixed income mutual funds may be higher than normal, potentially causing increased supply in the market due to selling activity.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Loan-Related Investments Risk. &lt;/b&gt;&amp;nbsp;In addition to risks generally associated with debt investments, loan-related investments such as loan participations and assignments are subject to other risks. Although a loan obligation may be fully collateralized at the time of acquisition, the collateral may decline in value, be relatively illiquid, or lose all or substantially all of its value subsequent to investment. Many loan investments are subject to legal or contractual restrictions on resale and may be relatively illiquid and difficult to value. There is less readily available, reliable information about most loan investments than is the case for many other types of securities. Substantial increases in interest rates may cause an increase in loan obligation defaults. With respect to loan participations, an Underlying Fund may not always have direct recourse against a borrower if the borrower fails to pay scheduled principal and/or interest; may be subject to greater delays, expenses and risks than if the Underlying Fund had purchased a direct obligation of the borrower; and may be regarded as the creditor of the agent lender (rather than the borrower), subjecting the Underlying Fund to the creditworthiness of that lender as well. The market for loan obligations may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods. Because transactions in many loans are subject to extended trade settlement periods, the Underlying Fund may not receive the proceeds from the sale of a loan for a period after the sale. As a result, sale proceeds related to the sale of loans may not be available to make additional investments or to meet the Underlying Fund&amp;#146;s redemption obligations for a period after the sale of the loans, and, as a result, the Underlying Fund may have to sell other investments or engage in borrowing transactions, such as borrowing from its credit facility, if necessary to raise cash to meet its obligations.&lt;br /&gt;&lt;br /&gt;Senior loans hold the most senior position in the capital structure of a business entity, and are typically secured with specific collateral, but are nevertheless usually rated below investment grade. Because second lien loans are subordinated or unsecured and thus lower in priority of payment to senior loans, they are subject to the additional risk that the cash flow of the borrower and property securing the loan or debt, if any, may be insufficient to meet scheduled payments after giving effect to the senior secured obligations of the borrower. Second lien loans generally have greater price volatility than senior loans and may be less liquid.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Management Risk.   &lt;/b&gt;&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 with respect to certain of the Underlying Funds 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;#146; historical trends, and technical issues in the construction and implementation of the models (including, for example, data problems and/or software issues). There is no guarantee that the Investment Adviser&amp;#146;s use of these quantitative models will result in effective investment decisions for an Underlying Fund. Additionally, commonality of holdings across quantitative money managers may amplify losses.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Market Risk. &lt;/b&gt;&amp;nbsp;The market value of the securities in which an Underlying 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;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;Mortgage-Backed and Other Asset-Backed Securities Risk.   &lt;/b&gt;&amp;nbsp;Mortgage-related and other asset-backed securities are subject to certain additional risks, including &amp;#147;extension risk&amp;#148; (i.e., in periods of rising interest rates, issuers may pay principal later than expected) and &amp;#147;prepayment risk&amp;#148; (i.e., in periods of declining interest rates, issuers may pay principal more quickly than expected, causing an Underlying 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;Municipal Securities Risk. &lt;/b&gt;&amp;nbsp;Municipal securities are subject to call/prepayment risk, credit/default risk, interest rate risk and certain additional risks. An Underlying Fund may be more sensitive to adverse economic, business or political developments if it invests a substantial portion of its assets in the bonds of similar projects (such as those relating to education, health care, housing, transportation, and utilities), industrial development bonds, or in particular types of municipal securities (such as general obligation bonds, private activity bonds and moral obligation bonds).&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Non-Diversification Risk. &lt;/b&gt;&amp;nbsp;Certain of the Underlying Funds are non-diversified, meaning that they are permitted to invest a larger percentage of their assets in fewer issuers than diversified mutual funds. Thus, an Underlying 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;Non-Hedging Foreign Currency Trading Risk&lt;/b&gt;.&amp;nbsp;  Certain Underlying Funds may engage in forward foreign currency transactions for investment purposes. An Underlying Fund&amp;#146;s investment adviser may purchase or sell foreign currencies through the use of forward contracts based on the investment adviser&amp;#146;s judgment regarding the direction of the market for a particular foreign currency or currencies. In pursuing this strategy, the Underlying Fund&amp;#146;s investment adviser seeks to profit from anticipated movements in currency rates by establishing &amp;#147;long&amp;#148; and/or &amp;#147;short&amp;#148; positions in forward contracts on various foreign currencies. Foreign exchange rates can be extremely volatile and a variance in the degree of volatility of the market or in the direction of the market from the investment adviser&amp;#146;s expectations may produce significant losses to the Underlying Fund. Some of these transactions may also be subject to interest rate risk.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Non-Investment Grade Fixed Income Securities Risk. &lt;/b&gt;&amp;nbsp;Non-investment grade fixed income securities and unrated securities of comparable credit quality (commonly known as &amp;#147;junk bonds&amp;#148;) are considered speculative and are subject to the increased risk of an issuer&amp;#146;s inability to meet principal and interest payment obligations. These securities may be subject to greater price volatility due to such factors as specific issuer developments, interest rate sensitivity, negative perceptions of the junk bond markets generally and less liquidity.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Portfolio Turnover Rate Risk. &lt;/b&gt;&amp;nbsp;A high rate of portfolio turnover (100% or more) involves correspondingly greater expenses which must be borne by an Underlying Fund and its shareholders (including the Portfolio), and is also likely to result in short-term capital gains taxable to shareholders of the Underlying Fund.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Real Estate Industry Risk&lt;/b&gt;.&amp;nbsp;  Risks associated with investments in the real estate industry include, among others: possible declines in the value of real estate; risks related to general and local economic conditions; possible lack of availability of mortgage financing, variations in rental income, neighborhood values or the appeal of property to tenants; interest rates; overbuilding; extended vacancies of properties; increases in competition, property taxes and operating expenses; and changes in zoning laws. The real estate industry is particularly sensitive to economic downturns. The values of securities of companies in the real estate industry may go through cycles of relative underperformance and out-performance in comparison to equity securities markets in general.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;REIT Risk&lt;/b&gt;.&amp;nbsp;  REITs whose underlying properties are concentrated in a particular industry or geographic region are subject to risks affecting such industries and regions. The securities of REITs involve greater risks than those associated with larger, more established companies and may be subject to more abrupt or erratic price movements because of interest rate changes, economic conditions and other factors. Securities of such issuers may lack sufficient market liquidity to enable an Underlying Fund to effect sales at an advantageous time or without a substantial drop in price.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Short Position Risk&lt;/b&gt;.&amp;nbsp;  An Underlying Fund may enter into a short position through a futures contract, an option or swap agreement or through short sales of any instrument that the Underlying Fund may purchase for investment. Taking short positions involves leverage of the Underlying Fund&amp;#146;s assets and presents various risks. If the value of the underlying instrument or market in which the Underlying Fund has taken a short position increases, then the Underlying Fund will incur a loss equal to the increase in value from the time that the short position was entered into plus any related interest payments or other fees. Taking short positions involves the risk that losses may be disproportionate, may exceed the amount invested and may be unlimited.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Sovereign Default Risk. &lt;/b&gt;&amp;nbsp;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. 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;Special Situation Investments Risk&lt;/b&gt;.&amp;nbsp;  An Underlying Fund may make investments in event-driven situations such as recapitalizations, financings, corporate and financial restructurings, acquisitions, divestitures, reorganizations or other situations in public or private companies that may provide the Underlying Fund with an opportunity to provide debt and/or equity financing, typically on a negotiated basis. The Investment Adviser of the Underlying Fund will seek special situation investment opportunities with limited downside risk relative to their potential upside. These investments are complicated and an incorrect assessment of the downside risk associated with an investment could result in significant losses to the Underlying Fund.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Stock Risk. &lt;/b&gt;&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.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Subsidiary Risk&lt;/b&gt;.&amp;nbsp;  The subsidiaries of certain Underlying Funds are not registered under the Investment Company Act of 1940, as amended (&amp;#147;Investment Company Act&amp;#148;) and are not subject to all the investor protections of the Investment Company Act. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of an Underlying Fund and/or its subsidiary to operate as intended and could adversely affect the Underlying Fund.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Swaps Risk&lt;/b&gt;.&amp;nbsp;  In a standard &amp;#147;swap&amp;#148; transaction, two parties agree to exchange the returns, differentials in rates of return or some other amount earned or realized on the &amp;#147;notional amount&amp;#148; 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;#146;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 an Underlying 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;Tax Risk&lt;/b&gt;.&amp;nbsp;  Certain Underlying Funds will seek to gain exposure to the commodity markets primarily through investments in a subsidiary and/or commodity index-linked structured notes. Historically, the Internal Revenue Service (&amp;#147;IRS&amp;#148;) has issued private letter rulings in which the IRS specifically concluded that income and gains from investments in commodity index-linked structured notes or a wholly-owned foreign subsidiary that invests in commodity-linked instruments are &amp;#147;qualifying income&amp;#148; for purposes of compliance with Subchapter M of the Internal Revenue Code of 1986, as amended (the &amp;#147;Code&amp;#148;). However, while certain Underlying Funds have received such a private letter ruling, others have not, and those that have not are unable to rely on private letter rulings issued to other taxpayers. Additionally, the IRS has suspended the granting of such private letter rulings, pending review of its position on this matter. The tax treatment of certain Underlying Funds&amp;#146; investments in a subsidiary or commodity index-linked structured notes may be adversely affected by future legislation, Treasury Regulations and/or guidance issued by the IRS (which may be retroactive) that could affect whether income derived from such investments is &amp;#147;qualifying income&amp;#148; under Subchapter M of Code, or otherwise affect the character, timing and/or amount of the Underlying Funds&amp;#146; taxable income or any gains and distributions made by the Underlying Funds. In connection with investments in a subsidiary and/or commodity index-linked structured notes, certain Underlying Funds have obtained or may seek to obtain an opinion of counsel that their income from such investments should constitute &amp;#147;qualifying income.&amp;#148; However, no assurances can be provided that the IRS would not be able to successfully assert that the Underlying Funds&amp;#146; income from such investments was not &amp;#147;qualifying income&amp;#148;, in which case an Underlying Fund would fail to qualify as a regulated investment company (RIC) under Subchapter M of the Code if over 10% of its gross income was derived from these investments. If an Underlying Fund failed to qualify as a RIC, it would be subject to federal and state income tax on all of its taxable income at regular corporate tax rates with no deduction for any distributions paid to shareholders, which would significantly adversely affect the returns to, and could cause substantial losses for, Underlying Fund shareholders.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Treasury Inflation Protected Securities Risk&lt;/b&gt;.&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;  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 those agencies, instrumentalities and sponsored enterprises, including those issued by the Federal National Mortgage Association (&amp;#147;Fannie Mae&amp;#148;), Federal Home Loan Mortgage Corporation (&amp;#147;Freddie Mac&amp;#148;) 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 an Underlying 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.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Further Information on Investment Objectives, Strategies and Risks of the Underlying Funds. &lt;/b&gt;&amp;nbsp;A concise description of the investment objectives, practices and risks of each of the Underlying Funds that are currently expected to be used for investment by the Portfolio as of the date of this Prospectus is provided beginning on page 14 of this Prospectus.</rr:RiskNarrativeTextBlock>

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01May2014_30Apr2015S000009355_MemberService_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;#147;Net Assets&amp;#148;) 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&gt;&amp;reg;&lt;/sup&gt; Index at the time of investment, which as of February 1, 2015 was between approximately $16 million and $11.2 billion. However, the Fund may invest in securities outside the Russell 2000&lt;sup&gt;&amp;reg;&lt;/sup&gt; Index capitalization range.&lt;br /&gt;&lt;br /&gt;The Fund uses a 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;#146;s investments are selected using fundamental research and a variety of quantitative techniques based on certain investment themes, including, among others, Momentum, Valuation and Profitability. 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 Valuation theme attempts to capture potential mispricings of securities, typically by comparing a measure of the company&amp;#146;s intrinsic value to its market value. The Profitability theme seeks to assess whether a company is earning more than its cost of capital. 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;#146;s proprietary research.&lt;br /&gt;&lt;br /&gt;The Fund maintains risk, style, and capitalization characteristics similar to the Russell 2000&lt;sup&gt;&amp;reg;&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;#146;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.&lt;br /&gt;&lt;br /&gt;The Fund&amp;#146;s benchmark index is the Russell 2000&lt;sup&gt;&amp;reg;&lt;/sup&gt; Index.</rr:StrategyNarrativeTextBlock>

Investments in the Fund involve 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;Different investment styles (e.g., &amp;#147;growth,&amp;#148; &amp;#147;value&amp;#148; or &amp;#147;quantitative&amp;#148;) tend to shift in and out of favor depending upon market and economic conditions and investor sentiment. The Fund employs a &amp;#147;quantitative&amp;#148; 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;Large Shareholder Transactions Risk.&lt;/b&gt; The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund&amp;#146;s net asset value (&amp;#147;NAV&amp;#148;) and liquidity. Similarly, large Fund share purchases may adversely affect the Fund&amp;#146;s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also increase transaction costs. In addition, a large redemption could result in the Fund&amp;#146;s current expenses being allocated over a smaller asset base, leading to an increase in the Fund&amp;#146;s expense ratio.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Management Risk.&lt;/b&gt; &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;#146; historical trends, and technical issues in the construction and implementation of the models (including, for example, data problems and/or software issues). There is no guarantee that the Investment Adviser&amp;#146;s use of these quantitative models will result in effective investment decisions for the Fund. Additionally, commonality of holdings across quantitative money managers may amplify losses.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Market Risk.&lt;/b&gt; &amp;nbsp;The 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;Mid-Cap and Small-Cap Risk.&lt;/b&gt; &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;Portfolio Turnover Rate Risk.&lt;/b&gt; &amp;nbsp;A high rate of portfolio turnover (100% or more) involves correspondingly greater expenses which must be borne by the Fund and its shareholders.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Stock Risk.&lt;/b&gt; &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 Investment Adviser believes that the Composite Index is a more appropriate index against which to measure performance in light of the fact that the Fund will employ active investment management techniques, which may involve buying and selling securities and other instruments potentially based upon analysis of economic and market factors, rather than passively investing in such instruments in order to seek to track an index.</rr:PerformanceTableMarketIndexChanged>

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;#147;Municipal Securities&amp;#148;) and convertible securities.&lt;br /&gt;&lt;br /&gt;The Fund may also engage in forward foreign currency transactions for both investment and hedging purposes. The Fund also intends to invest in derivatives, including (but not limited to) interest rate futures, interest rate swaps and credit default swaps, which are used primarily to hedge the Fund&amp;#146;s portfolio risks, manage the Fund&amp;#146;s duration and/or gain exposure to certain fixed income securities or indices.&lt;br /&gt;&lt;br /&gt;The Fund&amp;#146;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;#147;Total Assets&amp;#148;), and 10% of the Fund&amp;#146;s Total Assets may be invested in sovereign and corporate debt securities and other instruments of issuers in emerging market countries (&amp;#147;emerging countries debt&amp;#148;). Additionally, exposure to non-U.S. currencies (unhedged against currency risk) will not exceed 25% of the Fund&amp;#146;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;#150; or Baa3 at the time of purchase. Securities will either be rated by a nationally recognized statistical rating organization (&amp;#147;NRSRO&amp;#148;) or, if unrated, determined by the Investment Adviser to be of comparable credit quality.&lt;br /&gt;&lt;br /&gt;The Fund&amp;#146;s target duration range under normal interest rate conditions is expected to approximate that of the Index plus or minus one year, and over the ten years ended February 28, 2015, the duration of the Index has ranged between 3.71 and 5.65 years. &amp;#147;Duration&amp;#148; is a measure of a debt security&amp;#146;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;#146;s market price.&lt;br /&gt;&lt;br /&gt;The Fund&amp;#146;s benchmark index is the Barclays U.S. Aggregate Bond Index.</rr:StrategyNarrativeTextBlock>

These costs are not reflected in annual fund operating expenses or in the expense example above, but are reflected in the Fund&amp;#146;s performance.

  <rr:RiskNarrativeTextBlock contextRef="Duration_01May2014_30Apr2015S000009353_MemberService_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;#147;FDIC&amp;#148;) 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. Investments in the Fund involve 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 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;#146;s liquidity and cause significant deterioration in net asset value (&amp;#147;NAV&amp;#148;).&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Derivatives Risk.&lt;/b&gt; &amp;nbsp;Loss may result from the Fund&amp;#146;s investments in options, forwards, interest rate futures, interest rate swaps, credit default swaps and other derivative instruments. These instruments may be illiquid, difficult to price and leveraged so that small changes in the value of underlying instruments 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;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, sanctions, confiscations and other government restrictions by the United States or other governments, 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;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;Large Shareholder Transactions Risk.&lt;/b&gt; &amp;nbsp;The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund&amp;#146;s NAV and liquidity. Similarly, large Fund share purchases may adversely affect the Fund&amp;#146;s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also increase transaction costs. In addition, a large redemption could result in the Fund&amp;#146;s current expenses being allocated over a smaller asset base, leading to an increase in the Fund&amp;#146;s expense ratio.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Mortgage-Backed and Other Asset-Backed Securities Risk.&lt;/b&gt; &amp;nbsp;Mortgage-related and other asset-backed securities are subject to certain additional risks, including &amp;#147;extension risk&amp;#148; (i.e., in periods of rising interest rates, issuers may pay principal later than expected) and &amp;#147;prepayment risk&amp;#148; (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;#147;Fannie Mae&amp;#148;), Federal Home Loan Mortgage Corporation (&amp;#147;Freddie Mac&amp;#148;) 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 their 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>

  <rr:PortfolioTurnoverTextBlock contextRef="Duration_01May2014_30Apr2015S000035992_MemberInstitutional_Member">The Fund pays transaction costs when it buys and sells securities or instruments (i.e., &amp;#8220;turns over&amp;#8221; its portfolio). A high rate of portfolio turnover may result in increased transaction costs, including brokerage commissions, which must be borne by the Fund and its shareholders. These costs are not reflected in annual fund operating expenses or in the expense example above, but are reflected in the Fund&amp;#8217;s performance. The Fund&amp;#8217;s portfolio turnover rate for the fiscal year ended December 31, 2014 was 304% of the average value of its portfolio.</rr:PortfolioTurnoverTextBlock>
  <rr:StrategyNarrativeTextBlock contextRef="Duration_01May2014_30Apr2015S000035992_MemberInstitutional_Member">The Fund primarily seeks to achieve its investment objective by investing in a global portfolio of equity and fixed income asset classes. The Fund may invest in one or a combination of the following securities and instruments: pooled investment vehicles, including exchange-traded funds (&amp;#8220;ETFs&amp;#8221;) and other investment companies; equity securities and fixed income securities of U.S. and non-U.S. issuers; and derivatives that provide exposure to a broad spectrum of asset classes and geographic regions. Under normal market conditions, the Fund expects to invest at least 40% of its assets in equity investments and at least 20% of its assets in fixed income investments. The Investment Adviser makes investment decisions based upon its analysis of market factors around the world, and may allocate more of the Fund&amp;#8217;s assets to investments with strong recent performance and allocate assets away from investments with poor recent performance. The percentage of the Fund&amp;#8217;s portfolio exposed to any asset class or geographic region will vary from time to time as the weightings of the Fund change, and the Fund may not be invested in each asset class at all times. The Fund invests in at least three countries, including the United States, under normal market conditions. At times the Fund may be heavily invested in certain asset classes or geographic regions, depending on the asset allocation of the strategy. The Fund may invest without restriction as to issuer capitalization, currency, maturity or credit rating.&lt;br /&gt;&lt;br /&gt;As part of the Fund&amp;#8217;s investment strategy, the Investment Adviser seeks to manage volatility and limit losses by allocating the Fund&amp;#8217;s assets away from risky investments in distressed or volatile market environments. Volatility is a statistical measurement of the magnitude of up and down fluctuations in the value of a financial instrument or index. In distressed or volatile market environments, 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. While the Investment Adviser attempts to manage the Fund&amp;#8217;s volatility, there can be no guarantee that the Fund will be successful.&lt;br /&gt;&lt;br /&gt;The Fund&amp;#8217;s investments in derivatives may include: (i) futures contracts, including futures based on securities and/or indices; (ii) swaps, including interest rate, total return, variance, and/or index swaps, and swaps on futures contracts; (iii) options, including long and short positions in call options and put options on indices, or currencies, swaptions and options on futures contracts; and (iv) structured notes. The Fund may engage in forward foreign currency transactions for both investment and hedging purposes.&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.&lt;br /&gt;&lt;br /&gt;The Fund&amp;#8217;s blended benchmark is a composite of 60% Morgan Stanley Capital International (MSCI) World Index / 40% Barclays U.S. Aggregate Bond Index (the &amp;#8220;60% MSCI World / 40% Barclays U.S. Aggregate Composite Index&amp;#8221; or &amp;#8220;Composite Index&amp;#8221;), as discussed further under &amp;#8220;Performance.&amp;#8221;</rr:StrategyNarrativeTextBlock>

The Fund seeks to achieve its investment objective by investing, under normal circumstances, in approximately 60-80 companies that are considered by the Investment Adviser to be 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. The Fund may also invest in privately held companies and companies that only recently began to trade publicly.&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.&lt;br /&gt;&lt;br /&gt;The Fund&amp;#8217;s benchmark index is the Russell Midcap&lt;sup&gt;&amp;#174;&lt;/sup&gt; Growth Index.</rr:StrategyNarrativeTextBlock>

  <rr:RiskNarrativeTextBlock contextRef="Duration_01May2014_30Apr2015S000009360_MemberInstitutional_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. Investments in the Fund involve 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; 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;Large Shareholder Transactions Risk.&lt;/b&gt;&amp;nbsp; The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund&amp;#8217;s net asset value (&amp;#8220;NAV&amp;#8221;) and liquidity. Similarly, large Fund share purchases may adversely affect the Fund&amp;#8217;s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also increase transaction costs. In addition, a large redemption could result in the Fund&amp;#8217;s current expenses being allocated over a smaller asset base, leading to an increase in the Fund&amp;#8217;s expense ratio.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Market Risk.&lt;/b&gt;&amp;nbsp; The value of the securities 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; 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; 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:RiskNarrativeTextBlock contextRef="Duration_01May2014_30Apr2015S000035992_MemberInstitutional_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. Investments in the Fund involve 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;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;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 may be more pronounced.&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 options, futures, swaps, forwards, structured securities and other derivative instruments. These instruments may be illiquid, difficult to price and leveraged so that small changes in the value of the underlying instruments 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;By investing in pooled investment vehicles (including investment companies and ETFs), partnerships and real estate investment trusts (&amp;#8220;REITs&amp;#8221;) indirectly through the Fund, the investor will incur not only a proportionate share of the expenses of the pooled investment vehicles, partnerships and REITs held by the Fund (including operating costs and investment management fees), but also expenses of the Fund.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Foreign and Emerging Countries 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, sanctions, confiscations and other government restrictions by the United States and other governments, 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;Geographic Risk.&lt;/b&gt;  &amp;nbsp;Concentration of the investments of the Fund in issuers located in a particular country or region will subject the Fund, to a greater extent than if investments were less concentrated, to the risks of adverse securities markets, exchange rates and social, political, regulatory or economic events which may occur in that country or region.&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 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;Large Shareholder Transactions Risk.&lt;/b&gt;  &amp;nbsp;The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund&amp;#8217;s NAV and liquidity. Similarly, large Fund share purchases may adversely affect the Fund&amp;#8217;s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also increase transaction costs. In addition, a large redemption could result in the Fund&amp;#8217;s current expenses being allocated over a smaller asset base, leading to an increase in the Fund&amp;#8217;s expense ratio.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Leverage Risk.&lt;/b&gt;  &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. Borrowing and 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;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. Liquidity risk may be the result of, among other things, the reduced number and capacity of traditional market participants to make a market in fixed income securities or the lack of an active market. The potential for liquidity risk may be magnified by a rising interest rate environment or other circumstances where investor redemptions from fixed income mutual funds may be higher than normal, potentially causing increased supply in the market due to selling activity.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Management Risk.&lt;/b&gt;  &amp;nbsp;A strategy used by the Investment Adviser may fail to produce the intended results.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Market Risk.&lt;/b&gt;  &amp;nbsp;The 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;Mid-Cap and Small-Cap Risk.  &lt;/b&gt;  &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;NAV Risk.&lt;/b&gt;  &amp;nbsp;The net asset value (&amp;#8220;NAV&amp;#8221;) of the Fund and the value of your investment may fluctuate.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Non-Diversification Risk.&lt;/b&gt;  &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;Pooled Investments Risk.&lt;/b&gt;  &amp;nbsp;By investing in pooled investment vehicles (including investment companies and ETFs), partnerships and REITs indirectly through the Fund, investors will incur a proportionate share of the expenses of the other pooled investment vehicles, partnerships and REITs held by the Fund (including operating costs and investment management fees), in addition to the fees and expenses regularly borne by the Fund. In addition, the Fund will be affected by the investment policies, practices and performance of such investments in direct proportion to the amount of assets the Fund invests therein.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Portfolio Turnover Rate Risk.&lt;/b&gt;  &amp;nbsp;A high rate of portfolio turnover (100% or more) involves correspondingly greater expenses which must be borne by the Fund and its shareholders.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Sovereign Default Risk.&lt;/b&gt;  &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;Stock Risk.&lt;/b&gt;  &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.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Swaps Risk.&lt;/b&gt;  &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;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 issuers of U.S. Government securities will not have the funds to meet their payment obligations in the future.</rr:RiskNarrativeTextBlock>

  <rr:PerformanceNarrativeTextBlock contextRef="Duration_01May2014_30Apr2015S000035992_MemberInstitutional_Member">The bar chart and table below provide an indication of the risks of investing in the Fund by showing: (a) the performance of the Fund&amp;#8217;s Institutional Shares for its first full calendar year of operations; and (b) how the average annual total returns of the Fund&amp;#8217;s Institutional Shares compare to those of certain broad-based securities market indices and to the 60% MSCI World / 40% Barclays U.S. Aggregate Composite Index (the &amp;#8220;Composite Index&amp;#8221;), a composite representation prepared by the Investment Adviser of the performance of the Fund&amp;#8217;s asset classes weighted according to their respective weightings in the Fund&amp;#8217;s target range. The Composite Index is comprised of the Morgan Stanley Capital International (MSCI) World Index (60%) and the Barclays U.S. Aggregate Bond Index (40%). Through April 30, 2015, the Fund had been known as the Goldman Sachs Global Markets Navigator Fund, and its investment objective and certain of its strategies differed. Performance information prior to this date reflects the Fund&amp;#8217;s former investment objective and strategies. In addition, as of April 30, 2015 the Fund&amp;#8217;s benchmark index was changed from the Goldman Sachs Global Markets Navigator Index to the Composite Index. The Investment Adviser believes that the Composite Index is a more appropriate index against which to measure performance in light of the fact that the Fund will employ active investment management techniques, which may involve buying and selling securities and other instruments potentially based upon analysis of economic and market factors, rather than passively investing in such instruments in order to seek to track an index. 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. Had performance reflected all of those fees and expenses, performance would have been reduced.
