For the purposes of this restriction, &#8220;small-cap U.S. issuers&#8221; have public stock market capitalizations of companies constituting the Russell 2000&#174; Index, which as of February 1, 2011 was between $24 million and $5.2 billion. However, the Fund may invest in securities outside the Russell 2000&#174; capitalization range.</p><p>The Fund uses a &#8220;structured&#8221; quantitative style of management that emphasizes fundamentally-based stock selection, careful portfolio construction and efficient implementation. The Fund&#8217;s investments are selected using both a variety of quantitative techniques and fundamental research, based on six investment themes: Valuation, Profitability, Quality, Management, Momentum and Sentiment. The Valuation theme attempts to capture potential mispricings of securities, typically by comparing a measure of the company&#8217;s intrinsic value to its market value. Profitability assesses whether the company is earning more than its cost of capital. Quality evaluates whether the company&#8217;s earnings are coming from more persistent, cash based sources, as opposed to accruals. Management assesses the characteristics, policies and strategic decisions of company management. Momentum seeks to predict drifts in stock prices caused by under-reaction to company-specific information. Finally, the Sentiment theme reflects selected investment views and decisions of individuals and financial intermediaries.</p><p>The Fund maintains risk, style, capitalization and industry characteristics similar to the Russell 2000&#174; Growth Index, which is an index designed to represent an investable universe of small-cap companies with above average price to book ratios and earnings growth expectations. The Fund seeks to maximize expected return while maintaining these and other characteristics similar to the benchmark.</p><p>The Fund may also invest in fixed income securities considered to be cash equivalents.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation 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.</p><p><b><i>Stock Risk. </i></b>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.</p><p><b><i>Market Risk.</i></b> The value of the instruments in which the Fund invests may go up or down in response to the prospects of individual companies, particular industry sectors or governments and/or general economic conditions.</p><p><b><i>Mid-Cap and Small-Cap Risk.</i></b> Investments in mid-capitalization and small-capitalization companies involve greater risks than investments in 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.</p><p><b><i>Investment Style Risk.</i></b>Different investment styles (e.g., &#8220;growth&#8221;, &#8220;value&#8221; or &#8220;quantitative&#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.</p><p><b><i>Management Risk.</i></b>The risk that 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&#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&#8217;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.</p><p><b><i>Portfolio Turnover Rate Risk.</i></b> A high rate of portfolio turnover (100% or more) involves correspondingly greater expenses which must be borne by a Fund and its shareholders, and is also likely to result in short-term capital gains taxable to shareholders.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Shares only. The after-tax returns for Class B, Class C, Institutional and Class IR Shares, and returns for Class R Shares (which are offered exclusively to retirement plans), will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor&#8217;s tax situation and may differ from those shown. In addition, the after-tax returns shown are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringIf the Fund has annual returns for at least one calendar year, provide a table showing the Fund's (A) average annual total return; (B) average annual total return (after taxes on distributions); and (C) average annual total return (after taxes on distributions and redemption). A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also shouldshow the returns of an appropriate broadbased securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Paragraph 2 -Subparagraph iv -Subsection b falsefalsePerformance Table Narrative125Risk/Return Summary - Goldman Sachs Structured Small Cap Growth Fund) (Goldman Sachs Structured Small Cap Growth Fund, GOLDMAN SACHS STRUCTURED DOMESTIC EQUITY FUNDS)UnKnownUnKnownUnKnownUnKnownfalsetrue
