  <rr:StrategyNarrativeTextBlock contextRef="Duration_01Oct2011_30Sep2012S000012971_Member">In seeking to achieve its investment objective, the Fund may invest in a wide variety of investments such as equity securities, fixed-income securities, foreign securities, exchange-traded funds (ETFs) and derivative and hybrid instruments. Under normal conditions, the Fund's investment adviser ("Adviser") anticipates investing approximately 60% of the Fund's assets in equity securities and 40% of the Fund's assets in fixed-income securities and other investments. The Adviser may vary this allocation +/-20% depending upon its economic and market outlook as well as a result of the identification of favorable investment opportunities.&lt;br/&gt;&lt;br/&gt;The Adviser's investment strategy for the domestic equity portion of the Fund's portfolio (other than REITs) utilizes a whole market, all-cap/all-style approach by selecting most of its investments from companies listed in the Russell 3000&amp;#174; Index, an index that measures the performance of the 3,000 largest U.S. companies by market capitalization representing approximately 98% of the investable domestic equity market. As of July 31, 2012, companies in the Russell 3000&amp;#174; Index ranged in market capitalization from $46 million to $571 billion.&lt;br/&gt;&lt;br/&gt;In managing the Fund's allocation to foreign equities, the Adviser attempts to diversify the portfolio across countries, in companies of all sizes with both growth and value characteristics.&lt;br/&gt;&lt;br/&gt;The Fund's equity allocation may include investments in REITs. The Fund may obtain exposure to commodities by investing in instruments (including ETFs) whose performance is linked to the price of an underlying commodity or commodity index.&lt;br/&gt;&lt;br/&gt;With respect to the fixed-income securities allocation, the Fund invests primarily in domestic investment-grade debt securities, including corporate debt securities, U.S. government obligations and mortgage-backed securities. The Adviser selects fixed-income securities by using fundamental credit research to identify relative value in the market. The Adviser seeks to enhance the performance of the Fund's fixed-income portfolio by allocating more assets to the security type that the Adviser expects to offer the best balance between total return and risk.&lt;br/&gt;&lt;br/&gt;The Fund intends to invest in government securities which are issued or guaranteed by a federal agency or instrumentality acting under federal authority, including government securities that are not backed by the full faith and credit of the U.S. government.&lt;br/&gt;&lt;br/&gt;The Fund may also invest a portion of its portfolio in noninvestment-grade, fixed-income securities, when the Adviser considers the risk return prospects of those sectors to be attractive. The Fund may also invest a portion of its portfolio in non-U.S. dollar and emerging market fixed-income securities issued by entities such as foreign governments or foreign corporations when the Adviser considers the risk return prospects of those sectors to be attractive. The Fund may buy or sell foreign currencies in lieu of or in addition to non-dollar denominated fixed-income securities in order to increase or decrease its exposure to foreign interest and/or currency markets. The Adviser selects securities with longer or shorter durations based on its interest rate outlook, but does not target any specific duration for the fixed-income portion of the Fund.&lt;br/&gt;&lt;br/&gt;The Fund may invest in exchange-traded and over-the-counter derivatives, such as options or futures and hybrid instruments, for any purpose consistent with its investment strategy. The Adviser also may attempt to reach its goals by investing in exchange-traded funds and shares of other investment companies.&lt;br/&gt;&lt;br/&gt;For the domestic equity portion of the Fund, other than investments in real estate investment trusts (REITs), the Adviser implements its strategy using a quantitative computer model driven by fundamental stock selection variables, including company valuations, profit trends and earnings risks. This process, called the Optimum Q process, seeks to impose strict discipline over stock selection, unimpeded by market or manager psychology. It seeks to maximize compound annual return while controlling risk.&lt;br/&gt;&lt;br/&gt;The Fund actively trades its portfolio securities in an attempt to achieve its investment objective. Active trading will cause the Fund to have an increased portfolio turnover rate, which may generate shorter-term gains (losses) for its shareholders, which are taxed at a higher rate than longer-term gains (losses).

Emerging market countries may have relatively unstable governments and may present the risk of nationalization of businesses, expropriation, confiscatory taxation or, in certain instances, reversion to closed market, centrally planned economies. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Currency Risk.&lt;/b&gt; Exchange rates for currencies fluctuate daily. The Fund may use both spot trades and currency derivatives to increase or decrease its exposure to foreign interest rate and/or currency markets. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Interest Rate Risk.&lt;/b&gt; Prices of fixed-income securities generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer durations.&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Credit Risk.&lt;/b&gt; Credit risk is the possibility that an issuer will default on a security by failing to pay interest or principal when due. If an issuer defaults, the Fund will lose money. Credit risk includes the possibility that a party to a transaction (such as a derivative transaction) involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Call Risk.&lt;/b&gt; There is a possibility that an issuer of fixed-income securities in which the Fund may invest may redeem a security before maturity (a call) at a price below its current market price. An increase in the likelihood of a call may reduce the security's price.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Prepayment Risk.&lt;/b&gt; When homeowners prepay their mortgages in response to lower interest rates, the Fund will be required to reinvest the proceeds at the lower interest rates then available. Also, when interest rates fall, the price of mortgage-backed securities may not rise to as great an extent as that of other fixed-income securities. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Risk Associated with Noninvestment-Grade Securities.&lt;/b&gt; Securities rated below investment grade may be subject to greater interest rate, credit and liquidity risks than investment-grade securities.&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Exchange-Traded Funds Risk.&lt;/b&gt; An investment in an exchange-traded fund (ETF) generally presents the same primary risks as an investment in a conventional fund (i.e., one that is not exchange-traded). As with traditional mutual funds, ETFs charge asset-based fees. The change in value of the ETFs are due to the change in price of the securities in which the ETFs invest. Therefore, the Fund's net asset value will be indirectly effected by the change in value of the securities in which the ETF invests. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Risk of Investing in Derivative Contracts and Hybrid Instruments.&lt;/b&gt; Derivative contracts and hybrid instruments involve risks different from, or possibly greater than, risks associated with investing directly in securities and other traditional investments. Specific risk issues related to the use of such contracts and instruments include valuation and tax issues, increased potential for losses and/or costs to the Fund, and a potential reduction in gains to the Fund. Each of these issues is described in greater detail in this Prospectus. Derivative contracts and hybrid instruments may also involve other risks described in this Prospectus or the Fund's Statement of Additional Information (SAI) such as stock market, interest rate, credit, currency, liquidity and leverage risks. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Leverage Risk.&lt;/b&gt; Leverage risk is created when an investment (such as a derivative transaction) exposes the Fund to a level of risk that exceeds the amount invested. Changes in the value of such an investment magnify the Fund's risk of loss and potential for gain. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Risk of Investing in Commodities.&lt;/b&gt; Because the Fund may invest in instruments (including ETFs) whose performance is linked to the price of an underlying commodity or commodity index, the Fund may be subject to the risks of investing in physical commodities. These types of risks include regulatory, economic and political developments, weather events and natural disasters, pestilence, market disruptions and the fact that commodity prices may have greater volatility than investments in traditional securities. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Risk Related to the Economy. &lt;/b&gt;Lower-grade bond returns are sensitive to changes in the economy. The value of the Fund's portfolio may decline in tandem with a drop in the overall value of the stock market based on negative developments in the U.S. and global economies. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Liquidity Risk.&lt;/b&gt; The securities in which the Fund invests may be less readily marketable and may be subject to greater fluctuation in price than other securities. Liquidity risk also refers to the possibility that the Fund may not be able to sell a security or close out a derivative contract when it wants to. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Quantitative Modeling Risk. &lt;/b&gt;The Fund employs quantitative models as a management technique.

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01Oct2011_30Sep2012S000012973_Member">The Fund seeks to achieve its objective by investing primarily in the common stock of small U.S. companies. The Fund's investment adviser's (&amp;#8220;Adviser&amp;#8221;) investment strategy utilizes a small cap growth approach by selecting most of its investments from companies listed in the Russell 2000&lt;strong&gt;&amp;#174;&lt;/strong&gt; Growth Index, an index that measures the performance of those companies with higher price-to-book ratios and higher forecasted growth values within the small-cap segment of the U.S. equity universe, which includes the 2,000 smallest companies by market capitalization within the Russell 3000&lt;strong&gt;&amp;#174;&lt;/strong&gt; Index (an index that includes the 3,000 largest U.S. companies by market capitalization representing approximately 98% of the investable domestic equity market). As of July 31, 2012, companies in the Russell 2000&lt;strong&gt;&amp;#174;&lt;/strong&gt; Growth Index ranged in market capitalization from $46 million to $3.7 billion. As more fully described in this Prospectus, the Fund's investments may include, but are not limited to, equity securities of domestic issuers.&lt;br/&gt;&lt;br/&gt;The Adviser implements its strategy using a quantitative computer model driven by fundamental stock selection variables, including company valuations, capital structure and profit earnings. This process, called the Optimum Q process, seeks to impose strict discipline over stock selection, unimpeded by market or manager psychology. It seeks to maximize compound annual return while controlling risk. Under normal market conditions, the Fund invests at least 80% of its net assets in stocks of small-cap companies. The Fund considers small-cap companies to be those companies of a size similar to companies listed in the Russell 2000&lt;strong&gt;&amp;#174;&lt;/strong&gt; Growth Index.&lt;br/&gt;&lt;br/&gt;Because the Fund refers to small capitalization investments in its name, the Fund will notify shareholders at least 60 days in advance of any change in its investment policies that would permit the Fund to normally invest less than 80% of its assets (plus any borrowings for investment purposes) in investments in small companies. For purposes of this policy the Fund considers a small company to be a company of a size similar to companies listed on the Russell 2000&amp;#174; Growth Index.&lt;br/&gt;&lt;br/&gt;The Fund actively trades its portfolio securities in an attempt to achieve its investment objective. Active trading will cause the Fund to have an increased portfolio turnover rate, which may generate shorter-term gains (losses) for its shareholders, which are taxed at a higher rate than longer-term gains (losses). Actively trading portfolio securities increases the Fund's trading costs and may have an adverse impact on the Fund's performance.</rr:StrategyNarrativeTextBlock>

The primary factors that may reduce the Fund's returns include: &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;strong&gt;Stock Market Risk.&lt;/strong&gt; The value of equity securities in the Fund's portfolio will fluctuate and, as a result, the Fund's Share price may decline suddenly or over a sustained period of time. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;strong&gt;Risk Related to Company Size.&lt;/strong&gt; Because the smaller companies in which the Fund may invest may have unproven track records, a limited product or service base and limited access to capital, they may be more likely to fail than larger companies. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;strong&gt;Risk Related to Investing for Growth.&lt;/strong&gt; Due to their relatively high valuations, growth stocks are typically more volatile than value stocks. Additionally, growth stocks may not pay dividends or may pay lower dividends than value stocks. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;strong&gt;Sector Risk.&lt;/strong&gt; Because the Fund may allocate relatively more assets to certain industry sectors than others, the Fund's performance may be more susceptible to any developments which affect those sectors emphasized by the Fund. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;strong&gt;Liquidity Risk.&lt;/strong&gt; Trading opportunities are more limited for equity securities that are not widely held. This may make it more difficult to sell or buy a security at a favorable price or time. Consequently, the Fund may have to accept a lower price to sell a security, sell other securities to raise cash or give up an investment opportunity, any of which could have a negative effect on the Fund's performance. Infrequent trading of securities may also lead to an increase in their price volatility. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;strong&gt;Quantitative Modeling Risk. &lt;/strong&gt;The Fund employs quantitative models as a management technique. These models examine multiple economic factors using various proprietary and third-party data. The results generated by quantitative analysis may perform differently than expected and may negatively affect Fund performance for various reasons (for example, human judgment, data imprecision, software or other technology malfunctions, or programming inaccuracies). &lt;/li&gt;&lt;/ul&gt;The Shares offered by this Prospectus are not deposits or obligations of any bank, are not endorsed or guaranteed by any bank and are not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.</rr:RiskNarrativeTextBlock>
  <rr:StrategyNarrativeTextBlock contextRef="Duration_01Oct2011_30Sep2012S000012972_Member">The Fund seeks to achieve its objective by investing primarily in the common stock of small U.S. companies. Under normal market conditions, the Fund invests at least 80% of its net assets in stocks of small-cap companies. The Fund considers small-cap companies to be those companies of a size similar to companies listed in the Russell 2000&amp;#174; Index.&lt;br/&gt;&lt;br/&gt;The investment adviser&amp;#8217;s investment strategy utilizes a small-cap approach by selecting most of its investments from companies listed in the Russell 2000&amp;#174; Index, an index that measures the performance of the 2,000 smallest companies by market capitalization within the Russell 3000&amp;#174; Index (an index that includes the 3,000 largest U.S. companies by market capitalization, representing approximately 98% of the investable domestic equity market). As of July 31, 2012, companies in the Russell 2000&amp;#174; Index ranged in market capitalization from $46 million to $3.67 billion. As more fully described in this Prospectus, the Fund&amp;#8217;s investments may include, but are not limited to, equity securities of domestic issuers. &lt;br/&gt;&lt;br/&gt;The Fund&amp;#8217;s investment adviser implements its strategy using a quantitative computer model driven by fundamental stock selection variables, including company valuations, profit trends and earnings risks. This process, called the Optimum Q process, seeks to impose strict discipline over stock selection, unimpeded by market or manager psychology. It seeks to maximize compound annual return while controlling risk. &lt;br/&gt;&lt;br/&gt;Because the Fund refers to small-capitalization investments in its name, the Fund will notify shareholders at least 60 days in advance of any change in its investment policies that would permit the Fund to normally invest less than 80% of its net assets (plus any borrowings for investment purposes) in investments in small companies. For purposes of this limitation, small companies will be defined as companies with market capitalizations similar to companies in the Russell 2000&amp;#174; Index. &lt;br/&gt;&lt;br/&gt;The Fund actively trades its portfolio securities in an attempt to achieve its investment objective. Active trading will cause the Fund to have an increased portfolio turnover rate, which may generate shorter-term gains (losses) for its shareholders, which are taxed at a higher rate than longer-term gains (losses). Actively trading portfolio securities increases the Fund&amp;#8217;s trading costs and may have an adverse impact on the Fund&amp;#8217;s performance.</rr:StrategyNarrativeTextBlock>

Prior to that date, the Fund had no investment operations. Accordingly, the performance information and financial information provided in this Prospectus for periods prior to December 11, 2006, is historical information for the MDT Large Cap Growth Fund. The MDT Large Cap Growth Fund was managed by MDT Advisers and had similar investment objectives and strategies as the Fund.&lt;br/&gt;&lt;br/&gt;The bar chart and performance table below reflect historical data for the Fund and are intended to help you analyze the Fund's investment risks in light of its historical returns. The bar chart shows the variability of the Fund's IS class total returns on a calendar year-by-year basis. The Average Annual Total Return table shows returns &lt;em&gt;averaged&lt;/em&gt; over the stated periods, and includes comparative performance information. &lt;em&gt;The Fund's performance will fluctuate, and past performance (before and after taxes) is not necessarily an indication&lt;/em&gt; &lt;em&gt;of future results. &lt;/em&gt;Updated performance information for the Fund is available under the "Products" section at FederatedInvestors.com or by calling 1-800-341-7400.</rr:PerformanceNarrativeTextBlock>
