  <rr:RiskNarrativeTextBlock contextRef="Duration_01Jan2012_31Dec2012S000009728_Member">All mutual funds take investment risks. Therefore, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include: &lt;ul type="square"&gt;&lt;li style="margin-left:5px"&gt;&lt;b&gt;Stock Market Risk.&lt;/b&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:5px"&gt;&lt;b&gt;Liquidity Risk.&lt;/b&gt; The equity securities in which the Fund invests may be less readily marketable and may be subject to greater fluctuation in price than other securities.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:5px"&gt;&lt;b&gt;Risk Related to Company Size.&lt;/b&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:5px"&gt;&lt;b&gt;Medium-Sized Companies Risk.&lt;/b&gt; The Fund may invest in mid-size companies. Mid-capitalization companies often have narrower markets and limited managerial and financial resources compared to larger, more established companies. As a result, their performance can be more volatile and they face greater risk of business failure, which could increase the volatility of the Fund's portfolio. You should expect that the value of the Fund's Shares will be more volatile than a fund that invests exclusively in largecapitalization companies.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:5px"&gt;&lt;b&gt;Sector Risk.&lt;/b&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:5px"&gt;&lt;b&gt;Risk of Foreign Investing.&lt;/b&gt; Because the Fund may invest in securities issued by foreign companies, the Fund's Share price may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than could otherwise be the case.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:5px"&gt;&lt;b&gt;Custodial Services and Related Investment Costs.&lt;/b&gt; Custodial services and other costs relating to investment in international securities markets generally are more expensive than in the United States. Such markets have settlement and clearance procedures that differ from those in the United States. The inability of the Fund to make intended securities purchases due to settlement problems could cause the Fund to miss attractive investment opportunities. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:5px"&gt;&lt;b&gt;Currency Risk.&lt;/b&gt; Exchange rates for currencies fluctuate daily. The combination of currency risk and market risk tends to make securities traded in foreign markets more volatile than securities traded exclusively in the United States.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:5px"&gt;&lt;b&gt;Eurozone Related Risk.&lt;/b&gt; A number of countries in the European Union (EU) have experienced, and may continue to experience, severe economic and financial difficulties. Additional EU member countries may also fall subject to such difficulties. These events could negatively affect the value and liquidity of the Fund's investments in euro-denominated securities and derivatives contracts, securities of issuers located in the EU or with significant exposure to EU issuers or countries.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:5px"&gt;&lt;b&gt;Risk of Investing in ADRs and Domestically Traded Securities of Foreign Issuers.&lt;/b&gt; Because the Fund may invest in ADRs and other domestically traded securities of foreign companies, the Fund's Share price may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than would otherwise be the case.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:5px"&gt;&lt;b&gt;Technology Risk.&lt;/b&gt; Proprietary and third-party data and systems are utilized to support decision making for the Fund.  Data imprecision, software or other technology malfunctions, programming inaccuracies and similar circumstances may impair the performance of these systems, which may negatively affect Fund performance.&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:RiskNarrativeTextBlock contextRef="Duration_01Jan2012_31Dec2012ClassAbcShares_MemberS000009729_Member">All mutual funds take investment risks. Therefore, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include:&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;b&gt;Stock Market Risk.&lt;/b&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: 5px"&gt;&lt;b&gt;Risk Related to Investing for Growth.&lt;/b&gt; Due to their relatively high valuations, growth stocks are typically more volatile than value stocks. For instance, the price of a growth stock may experience a larger decline on a forecast of lower earnings, a negative fundamental development, or an adverse market development. Further, growth stocks may not pay dividends or may pay lower dividends than value stocks. This means they depend more on price changes for returns and may be more adversely affected in a down market compared to value stocks that pay higher dividends.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;b&gt;Risk Related to Company Size.&lt;/b&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: 5px"&gt;&lt;b&gt;Sector Risk.&lt;/b&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: 5px"&gt;&lt;b&gt;Liquidity Risk.&lt;/b&gt; The equity securities in which the Fund invests may be less readily marketable and may be subject to greater fluctuation in price than other securities.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;b&gt;Risk of Foreign Investing.&lt;/b&gt; Because the Fund invests in securities issued by foreign companies, the Fund's Share price may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than could otherwise be the case.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;b&gt;Risk of Investing in ADRs and Domestically Traded Securities of Foreign Issuers.&lt;/b&gt; Because the Fund may invest in ADRs and other domestically traded securities of foreign companies, the Fund's Share price may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than would otherwise be the case.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;b&gt;Risk of Investing in Emerging Market Countries.&lt;/b&gt; Securities issued or traded in emerging markets generally entail greater risks than securities issued or traded in developed markets. 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: 5px"&gt;&lt;b&gt;Custodial Services and Related Investment Costs.&lt;/b&gt; Custodial services and other costs relating to investment in international securities markets generally are more expensive due to differing settlement and clearance procedures than those of the United States. The inability of the Fund to make intended securities purchases due to settlement problems could cause the Fund to miss attractive investment opportunities. In addition, security settlement and clearance procedures in some emerging market countries may not fully protect the Fund against loss of its assets.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;b&gt;Currency Risk.&lt;/b&gt; Exchange rates for currencies fluctuate daily. Foreign securities are normally denominated and traded in foreign currencies. As a result, the value of the Fund's foreign investments and the value of the Shares may be affected favorably or unfavorably by changes in currency exchange rates relative to the U.S. dollar.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;b&gt;Eurozone Related Risk.&lt;/b&gt; A number of countries in the European Union (EU) have experienced, and may continue to experience, severe economic and financial difficulties. Additional EU member countries may also fall subject to such difficulties. These events could negatively affect the value and liquidity of the Fund's investments in euro-denominated securities and derivatives contracts, securities of issuers located in the EU or with significant exposure to EU issuers or countries.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&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 involve other risks described in this Prospectus or the Fund's Statement of Additional Information (SAI), such as stock market, credit, currency, liquidity and leverage risks.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;b&gt;Credit Risk.&lt;/b&gt; 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: 5px"&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: 5px"&gt;&lt;b&gt;Interest Rate Risk.&lt;/b&gt; Prices of fixed-income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&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) that has the same investment objectives, strategies and policies. The price of an ETF can fluctuate up or down, and the Fund could lose money investing in an ETF if the prices of the securities owned by the ETF go down.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;b&gt;Technology Risk.&lt;/b&gt; Proprietary and third-party data and systems are utilized to support decision making for the Fund. Data imprecision, software or other technology malfunctions, programming inaccuracies and similar circumstances may impair the performance of these systems, which may negatively affect Fund performance.&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:RiskNarrativeTextBlock contextRef="Duration_01Jan2012_31Dec2012ClassRShares_MemberS000009729_Member">All mutual funds take investment risks. Therefore, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include:&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;b&gt;Stock Market Risk.&lt;/b&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: 5px"&gt;&lt;b&gt;Risk Related to Investing for Growth.&lt;/b&gt; Due to their relatively high valuations, growth stocks are typically more volatile than value stocks. For instance, the price of a growth stock may experience a larger decline on a forecast of lower earnings, a negative fundamental development, or an adverse market development. Further, growth stocks may not pay dividends or may pay lower dividends than value stocks. This means they depend more on price changes for returns and may be more adversely affected in a down market compared to value stocks that pay higher dividends.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;b&gt;Risk Related to Company Size.&lt;/b&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: 5px"&gt;&lt;b&gt;Sector Risk.&lt;/b&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: 5px"&gt;&lt;b&gt;Liquidity Risk.&lt;/b&gt; The equity securities in which the Fund invests may be less readily marketable and may be subject to greater fluctuation in price than other securities.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;b&gt;Risk of Foreign Investing.&lt;/b&gt; Because the Fund invests in securities issued by foreign companies, the Fund's Share price may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than could otherwise be the case.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;b&gt;Risk of Investing in ADRs and Domestically Traded Securities of Foreign Issuers.&lt;/b&gt; Because the Fund may invest in ADRs and other domestically traded securities of foreign companies, the Fund's Share price may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than would otherwise be the case.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;b&gt;Risk of Investing in Emerging Market Countries.&lt;/b&gt; Securities issued or traded in emerging markets generally entail greater risks than securities issued or traded in developed markets. 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: 5px"&gt;&lt;b&gt;Custodial Services and Related Investment Costs.&lt;/b&gt; Custodial services and other costs relating to investment in international securities markets generally are more expensive due to differing settlement and clearance procedures than those of the United States. The inability of the Fund to make intended securities purchases due to settlement problems could cause the Fund to miss attractive investment opportunities. In addition, security settlement and clearance procedures in some emerging market countries may not fully protect the Fund against loss of its assets.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;b&gt;Currency Risk.&lt;/b&gt; Exchange rates for currencies fluctuate daily. Foreign securities are normally denominated and traded in foreign currencies. As a result, the value of the Fund's foreign investments and the value of the Shares may be affected favorably or unfavorably by changes in currency exchange rates relative to the U.S. dollar.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;b&gt;Eurozone Related Risk.&lt;/b&gt; A number of countries in the European Union (EU) have experienced, and may continue to experience, severe economic and financial difficulties. Additional EU member countries may also fall subject to such difficulties. These events could negatively affect the value and liquidity of the Fund's investments in euro-denominated securities and derivatives contracts, securities of issuers located in the EU or with significant exposure to EU issuers or countries.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&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 involve other risks described in this Prospectus or the Fund's Statement of Additional Information (SAI), such as stock market, credit, currency, liquidity and leverage risks.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;b&gt;Credit Risk.&lt;/b&gt; 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: 5px"&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: 5px"&gt;&lt;b&gt;Interest Rate Risk.&lt;/b&gt; Prices of fixed-income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&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) that has the same investment objectives, strategies and policies. The price of an ETF can fluctuate up or down, and the Fund could lose money investing in an ETF if the prices of the securities owned by the ETF go down.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;b&gt;Technology Risk.&lt;/b&gt; Proprietary and third-party data and systems are utilized to support decision making for the Fund. Data imprecision, software or other technology malfunctions, programming inaccuracies and similar circumstances may impair the performance of these systems, which may negatively affect Fund performance.&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>

The market capitalization of companies of the Russell 1000 Index ranged from approximately $309 million to $556.5 billion as of October 31, 2012. As of October 31, 2012, the market capitalizations of companies within the top 75&lt;sup&gt;th&lt;/sup&gt; percentile of the Russell 1000 Index ranged from $14.2 billion to $556.5 billion. &lt;br/&gt;&lt;br/&gt;The Fund will normally invest at least 80% of its assets (which include the amount of any borrowings for investment purposes) in large-cap companies and 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 in investments in large companies. Such definition will be applied at the time of investment and the Fund will not be required to sell a stock because a company has fallen outside the market capitalization range of large capitalization stocks. Up to 30% of the Fund's net assets may be invested in foreign securities in both developed and emerging markets. The Adviser's and Sub-Adviser's (collectively, "Adviser'') process for selecting investments is bottom-up and growth-oriented.&lt;br/&gt;&lt;br/&gt; The Fund may invest in fixed-income securities, exchange-traded funds, American Depositary Receipts and use derivative contracts and/or hybrid instruments to implement elements of its investment strategy.</rr:StrategyNarrativeTextBlock>

  <rr:RiskNarrativeTextBlock contextRef="Duration_01Jan2012_31Dec2012S000019678_Member">All mutual funds take investment risks. Therefore, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include: &lt;ul type="square"&gt;&lt;li style="margin-left:5px"&gt; &lt;b&gt;Stock Market Risk.&lt;/b&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:5px"&gt;&lt;b&gt;Sector Risk.&lt;/b&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:5px"&gt;&lt;b&gt;Risk Related to Investing for Growth.&lt;/b&gt; Due to their relatively high valuations, growth stocks are typically more volatile than value stocks. For instance, the price of a growth stock may experience a larger decline on a forecast of lower earnings, a negative fundamental development, or an adverse market development. Further, growth stocks may not pay dividends or may pay lower dividends than value stocks. This means they depend more on price changes for returns and may be more adversely affected in a down market compared to value stocks that pay higher dividends. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:5px"&gt;&lt;b&gt;Risk of Foreign Investing.&lt;/b&gt; Because the Fund invests in securities issued by foreign companies, the Fund's Share price may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than could otherwise be the case. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:5px"&gt;&lt;b&gt;Risk of Investing in American Depositary Receipts and Domestically Traded Securities of Foreign Issuers.&lt;/b&gt; Because the Fund may invest in American Depositary Receipts and other domestically traded securities of foreign companies, the Fund's Share price may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than would otherwise be the case. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:5px"&gt;&lt;b&gt;Risk of Investing in Emerging Market Countries.&lt;/b&gt; Securities issued or traded in emerging markets generally entail greater risk than securities issued or traded in developed markets. For example, their prices can be significantly more volatile than prices in developed countries. Emerging market economies may also experience more severe downturns (with corresponding currency devaluations) than developed economies. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:5px"&gt;&lt;b&gt;Currency Risk.&lt;/b&gt; Exchange rates for currencies fluctuate daily. Foreign securities are normally denominated and traded in foreign currencies. As a result, the value of the Fund's foreign investments and the value of the shares may be affected favorably or unfavorably by changes in currency exchange rates relative to the U.S. dollar. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:5px"&gt;&lt;b&gt;Eurozone Related Risk.&lt;/b&gt; A number of countries in the European Union (EU) have experienced, and may continue to experience, severe economic and financial difficulties. Additional EU member countries may also fall subject to such difficulties. These events could negatively affect the value and liquidity of the Fund's investments in euro-denominated securities and derivatives contracts, securities of issuers located in the EU or with significant exposure to EU issuers or countries. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:5px"&gt;&lt;b&gt;Custodial Services and Related Investment Costs.&lt;/b&gt; Custodial services and other costs relating to investment in international securities markets generally are more expensive than in the United States. Such markets have settlement and clearance procedures that differ from those in the United States. Security settlement and clearance procedures in some emerging market countries may not fully protect the Fund against loss of its assets. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:5px"&gt;&lt;b&gt;Liquidity Risk.&lt;/b&gt; Liquidity risk 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. If this happens, the Fund will be required to continue to hold the security or keep the position open, and the Fund could incur losses. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:5px"&gt;&lt;b&gt;Risk of Investing in Derivative Contracts and Hybrid Instruments.&lt;/b&gt; Derivative contracts and hybrid instruments involve risk different from, or possibly greater than, risk 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 risk described in this Prospectus or the Fund's Statement of Additional Information, such as stock market, credit, currency, liquidity and leverage risk. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:5px"&gt;&lt;b&gt;Exchange-Traded Funds Risk.&lt;/b&gt; An investment in an exchange-traded fund (ETF) generally presents the same primary risk as an investment in a conventional fund (i.e., one that is not exchange-traded) that has the same investment objectives, strategies, and policies. The price of an ETF can fluctuate up or down, and the Fund could lose money investing in an ETF if the prices of the securities owned by the ETF go down. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:5px"&gt;&lt;b&gt;Leverage Risk.&lt;/b&gt; Leverage risk is created when an investment 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:5px"&gt;&lt;b&gt;Credit Risk.&lt;/b&gt; Credit risk includes the possibility that a party to a 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:5px"&gt;&lt;b&gt;Interest Rate Risk.&lt;/b&gt; Prices of fixed-income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally when interest rates rise, prices of fixed-income securities fall. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:5px"&gt;&lt;b&gt;Technology Risk.&lt;/b&gt; Proprietary and third-party data and systems are utilized to support decision making for the Fund. Data imprecision, software or other technology malfunctions, programming inaccuracies and similar circumstances may impair the performance of these systems, which may negatively affect Fund performance. &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_01Jan2012_31Dec2012S000009730_Member">The Fund pursues its investment objective by investing primarily in the common stocks of small companies that are traded on national security exchanges, the NASDAQ stock market and on the over-the-counter market. Small companies will be defined as companies with market capitalizations similar to companies in the Russell 2000 Index (which had a market capitalization range of $26 million to $5.2 billion as of October 31, 2012) or the Standard &amp;amp; Poor's Small Cap 600 Index (which had a market capitalization range of $34.6 million to $3.6 billion as of October 31, 2012). The Fund will normally invest at least 80% of its assets (which include the amount of any borrowing for investment purposes) in small companies and 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 in investments in small companies. Such definition will be applied at the time of investment and the Fund will not be required to sell a stock because a company has grown outside the market capitalization range of small capitalization stocks. Up to 30% of the Fund's net assets may be invested in foreign securities. The Adviser's and Sub-Adviser's (collectively, "Adviser") process for selecting investments is bottom-up and growth-oriented.&lt;br/&gt;&lt;br/&gt;The Fund may invest in fixed-income securities, exchange-traded funds, American Depositary Receipts and use derivative contracts and/or hybrid instruments to implement elements of its investment strategy.</rr:StrategyNarrativeTextBlock>

  <rr:RiskNarrativeTextBlock contextRef="Duration_01Jan2012_31Dec2012S000009730_Member">All mutual funds take investment risks. Therefore, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include:&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;b&gt;Stock Market Risk. &lt;/b&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: 5px"&gt;&lt;b&gt;Risk Related to Investing for Growth. &lt;/b&gt; Due to their relatively high valuations, growth stocks are typically more volatile than value stocks. For instance, the price of a growth stock may experience a larger decline on a forecast of lower earnings, a negative fundamental development, or an adverse market development. Further, growth stocks may not pay dividends or may pay lower dividends than value stocks. This means they depend more on price changes for returns and may be more adversely affected in a down market compared to value stocks that pay higher dividends.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;b&gt;Risk Related to Company Size. &lt;/b&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: 5px"&gt;&lt;b&gt;Sector Risk. &lt;/b&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: 5px"&gt;&lt;b&gt;Liquidity Risk. &lt;/b&gt; The equity securities in which the Fund invests may be less readily marketable and may be subject to greater fluctuation in price than other securities.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;b&gt;Risk of Foreign Investing. &lt;/b&gt; Because the Fund invests in securities issued by foreign companies, the Fund's Share price may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than could otherwise be the case.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;b&gt;Risk of Investing in American Depositary Receipts and Domestically Traded Securities of Foreign Issuers. &lt;/b&gt; Because the Fund may invest in American Depositary Receipts and other domestically traded securities of foreign companies, the Fund's Share price may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than would otherwise be the case.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;b&gt;Risk of Investing in Emerging Markets Countries. &lt;/b&gt; Securities issued or traded in emerging markets generally entail greater risks than securities issued or traded in developed markets. For example, their prices can be significantly more volatile than prices in developed countries. Emerging market economies may also experience more severe downturns (with corresponding currency devaluations) than developed economies. 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: 5px"&gt;&lt;b&gt;Custodial Services and Related Investment Costs. &lt;/b&gt; Custodial services and other costs relating to investment in international securities markets generally are more expensive due to differing settlement and clearance procedures than those of the United States. The inability of the Fund to make intended securities purchases due to settlement problems could cause the Fund to miss attractive investment opportunities. In addition, security settlement and clearance procedures in some emerging market countries may not fully protect the Fund against loss of its assets.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;b&gt;Currency Risk. &lt;/b&gt; Exchange rates for currencies fluctuate daily. Foreign securities are normally denominated and traded in foreign currencies. As a result, the value of the Fund's foreign investments and the value of the shares may be affected favorably or unfavorably by changes in currency exchange rates relative to the U.S. dollar.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;b&gt;Eurozone Related Risk. &lt;/b&gt; A number of countries in the European Union (EU) have experienced, and may continue to experience, severe economic and financial difficulties. Additional EU member countries may also fall subject to such difficulties. These events could negatively affect the value and liquidity of the Fund's investments in euro-denominated securities and derivatives contracts, securities of issuers located in the EU or with significant exposure to EU issuers or countries.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&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, such as stock market, credit, currency, liquidity and leverage risks.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;b&gt;Credit Risk. &lt;/b&gt; Credit risk includes the possibility that a party to a 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: 5px"&gt;&lt;b&gt;Leverage Risk. &lt;/b&gt; Leverage risk is created when an investment 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: 5px"&gt;&lt;b&gt;Interest Rate Risk. &lt;/b&gt; Prices of fixed-income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally when interest rates rise, prices of fixed-income securities fall.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&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) that has the same investment objectives, strategies and policies. The price of an ETF can fluctuate up or down, and the Fund could lose money investing in an ETF if the prices of the securities owned by the ETF go down.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;b&gt;Technology Risk. &lt;/b&gt; Proprietary and third-party data systems are utilized to support decision making for the Fund. Data imprecision, software or other technology malfunctions, programming inaccuracies and similar circumstances may impair the performance of these systems, which may negatively affect Fund performance. &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:RiskNarrativeTextBlock contextRef="Duration_01Jan2012_31Dec2012S000009734_Member">All mutual funds take investment risks. Therefore, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include:&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;b&gt;Stock Market Risk.&lt;/b&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: 5px"&gt;&lt;b&gt;Risk Related to Investing for Value.&lt;/b&gt; Due to their relatively low valuations, value stocks are typically less volatile than growth stocks and more likely to pay higher dividends. The Fund's strategy contemplates investing in stocks focused on paying high dividends. Accordingly, the Fund's performance may lag behind the general market when dividend paying stocks are out of favor. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;b&gt;Risk of Foreign Investing.&lt;/b&gt; Because the Fund invests in securities issued by foreign companies, the Fund's Share price may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than would otherwise be the case.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;b&gt;Risk of Investing in ADRs and Domestically-Traded Securities of Foreign Issuers.&lt;/b&gt; Because the Fund may invest in American Depositary Receipts (ADRs) and other domestically-traded securities of foreign companies, the Fund's Share price may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than would otherwise be the case. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;b&gt;Custodial Services and Related Investment Costs.&lt;/b&gt; Custodial services and other costs relating to investment in international securities markets generally are more expensive than in the United States. Such markets have settlement and clearance procedures that differ from those in the United States. The inability of the Fund to make intended securities purchases due to settlement problems could cause the Fund to miss attractive investment opportunities.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;b&gt;Currency Risk. &lt;/b&gt;Exchange rates for currencies fluctuate daily. The combination of currency risk and stock market risk tends to make securities traded in foreign markets more volatile than securities traded exclusively in the United States. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;b&gt;Eurozone Related Risk.&lt;/b&gt; A number of countries in the European Union (EU) have experienced, and may continue to experience, severe economic and financial difficulties. Additional EU member countries may also fall subject to such difficulties. These events could negatively affect the value and liquidity of the Fund's investments in euro-denominated securities and derivatives contracts, securities of issuers located in the EU or with significant exposure to EU issuers or countries. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;b&gt;Sector Risk.&lt;/b&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: 5px"&gt;&lt;b&gt;Liquidity Risk.&lt;/b&gt; The equity securities in which the Fund invests may be less readily marketable and may be subject to greater fluctuation in price than other securities. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;b&gt;Risks of Investing in Derivative Contracts.&lt;/b&gt; Derivative contracts 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 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 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: 5px"&gt;&lt;b&gt;Technology Risk.&lt;/b&gt; Proprietary and third party data and systems are utilized to support decision making for the Fund. Data imprecision, software or other technology malfunctions, programming inaccuracies and similar circumstances may impair the performance of these systems, which may negatively affect Fund performance. &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_01Jan2012_31Dec2012S000009734_Member">The Fund pursues its investment objective by investing primarily in high dividend yielding common stocks with dividend growth potential. The Adviser believes a strategic emphasis on high dividend yielding stocks can enhance both relative and absolute performance over time. In addition, investment results can be enhanced by focusing on stocks with both the potential for future dividend growth and current dividend-oriented value characteristics. The Adviser believes that this is achievable while targeting significantly less risk.&lt;br/&gt;&lt;br/&gt;  The Fund's security selection process involves screening and prioritizing stocks based on appropriate quantitative statistics. Those companies that rank as highly attractive in the screening process are closely scrutinized for inclusion in the portfolio using bottom-up fundamental proprietary research. The Fund may use derivative contracts, such as forward contracts, to manage or hedge the Fund's currency exposure.&lt;br/&gt;&lt;br/&gt;  Because the Fund refers to dividends in its name, it will notify shareholders at least 60 days in advance of any change in its investment policies that would enable the Fund to normally invest less than 80% of its net assets (plus any borrowings for investment purposes) in dividend-paying securities.</rr:StrategyNarrativeTextBlock>

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01Jan2012_31Dec2012S000009732_Member">The Fund pursues its investment objective by investing primarily in domestic (including American Depositary Receipts (ADRs)) and foreign securities (including emerging markets), both debt and equity, that the Adviser deems to be misvalued or misperceived. The Adviser can position the Fund with respect to various asset classes or individual securities in a net long or a net short position.&lt;br/&gt;&lt;br/&gt;The Adviser's investment management approach involves both "top-down" and "bottom-up" processes. The top-down process influences asset allocation and also provides context for security selection. The investment framework involves judgment of risk versus reward potential and the likelihood of positive absolute returns. The assessment of risk versus reward involves careful macroeconomic analysis, study of global financial and liquidity conditions, and analysis of market expectations. The bottom-up equity security selection is driven by consideration of valuation, financial statements and expectations. An expectations opportunity is deemed to exist when the Adviser's view deviates from the consensus view on individual securities or groups of securities.&lt;br/&gt;&lt;br/&gt;The Fund may invest in exchange-traded funds (ETFs), derivative contracts (such as options, swaps and futures contracts) and hybrid investments (such as notes linked to underlying securities, indices or commodities), or sell securities short or obtain short exposure through a derivative contract or investment in another fund in order to implement its investment strategy. The Fund may buy or sell foreign currencies or enter into foreign currency forwards in lieu of or in addition to non-dollar denominated fixed-income securities in order to increase or decrease its exposure to foreign interest rate and/or currency markets. When investing the fixed-income portion of the Fund, the Adviser is not constrained by any duration or maturity range or credit quality.&lt;br/&gt;&lt;br/&gt;The Fund may invest in certain commodity ETFs, closed-end funds that hold commodities, and derivative or other hybrid instruments whose price depends upon the movement of an underlying commodity or by the performance of a commodity index. In addition, the Fund may invest directly in gold bullion. When investing in gold bullion, the Fund may take possession of gold bullion and store such gold bullion at a custodian or subcustodian.</rr:StrategyNarrativeTextBlock>

  <rr:RiskNarrativeTextBlock contextRef="Duration_01Jan2012_31Dec2012S000009732_Member">All mutual funds take investment risks. Therefore, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include:&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;&lt;b&gt;Stock Market Risk.&lt;/b&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;b&gt;Risk Relating to Investing for Value.&lt;/b&gt; The Fund uses a "value" style of investing and, as a result, the Fund's Share price may lag that of other funds using a different investment style.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;&lt;b&gt;Risk of Foreign Investing.&lt;/b&gt; Because the Fund invests in securities issued by foreign companies, the Fund's Share price may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than would otherwise be the case.&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 ADRs and Domestically Traded Securities of Foreign Issuers.&lt;/b&gt; Because the Fund may invest in ADRs and other domestically traded securities of foreign companies, the Fund's Share price may be more affected by risks of foreign investing than would otherwise be the case.&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. Foreign securities are normally denominated and traded in foreign currencies. As a result, the value of the Fund's foreign investments and the value of the Shares may be affected favorably or unfavorably by changes in currency exchange rates relative to the U.S. dollar.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;&lt;b&gt;Eurozone Related Risk.&lt;/b&gt; A number of countries in the European Union (EU) have experienced, and may continue to experience, severe economic and financial difficulties. Additional EU member countries may also fall subject to such difficulties. These events could negatively affect the value and liquidity of the Fund's investments in euro-denominated securities and derivatives contracts, securities of issuers located in the EU or with significant exposure to EU issuers or countries.&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 Emerging Market Countries.&lt;/b&gt; Securities issued or traded in emerging markets generally entail greater risks than securities issued or traded in developed markets. Emerging market economies may also experience more actual or perceived severe downturns (with corresponding currency devaluation) than developed economies.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;&lt;b&gt;Sector Risk.&lt;/b&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;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, 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;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 of Investing in Gold Bullion.&lt;/b&gt; The Fund's investment in gold bullion could cause the Fund to fail to qualify as a regulated investment company (RIC) under Subchapter M of the Internal Revenue Code. It is the intent of the Fund to maintain its RIC status, and as such, the Fund will seek to manage its investment in gold bullion in an effort to continue to qualify as a RIC (for example, by altering the timing and/or amount of gold bullion transactions). However, there are no assurances it will be successful in doing so. Custodial services and other costs relating to investment in gold bullion are generally more expensive than those associated with investing in securities. The inability of the Fund to make intended purchases of gold bullion due to settlement problems could cause the Fund to not be fully protected against the loss of its assets or cause the Fund to miss attractive investment opportunities.&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. Duration measures the price sensitivity of a fixed-income security to changes in interest rates.&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.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;&lt;b&gt;Risk of Loss After Redemption.&lt;/b&gt; The Fund may also invest in trade finance loan instruments primarily by investing in: (1) other investment companies (which are not available for general investment by the public) that own those instruments, are advised by an affiliate of the Adviser and are structured as an extended payment fund; or (2) private investment funds that own those instruments.&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, also known as junk bonds, generally entail greater economic, credit and liquidity risks than investment-grade securities. For example, their prices are more volatile, economic downturns and financial setbacks may affect their prices more negatively, and their trading market may be more limited.&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;Risk Related to the Economy.&lt;/b&gt; Low-grade corporate 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;Leverage Risk.&lt;/b&gt; Leverage risk is created when an investment, which includes, for example, an investment in a derivative contract, 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;li style="margin-left: -20px"&gt;&lt;b&gt;Exchange-Traded Funds Risk.&lt;/b&gt; An investment in an ETF generally presents the same primary risks as an investment in a conventional fund (i.e., one that is not exchange-traded) that has the same investment objectives, strategies and policies. The price of an ETF can fluctuate up or down, and the Fund could lose money investing in an ETF if the prices of the securities owned by the ETF go down.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;&lt;b&gt;Short Selling Risk.&lt;/b&gt; The Fund may enter into short sales which expose the Fund to the risks of short selling. Short sales involve borrowing a security from a lender which is then sold in the open market at a future date. The security is then repurchased by the Fund and returned to the lender. Short selling allows an investor to profit from declines in prices of securities. Short selling a security involves the risk that the security sold short will appreciate in value at the time of repurchase therefore creating a loss for the Fund. The Fund may incur expenses in selling securities short and such expenses are investment expenses of the Fund.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;&lt;b&gt;Technology Risk.&lt;/b&gt; Proprietary and third-party data and systems are utilized to support decision making for the Fund. Data imprecision, software or other technology malfunctions, programming inaccuracies and similar circumstances may impair the performance of these systems, which may negatively affect Fund performance.&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>

For the period prior to the commencement of operations of the IS class, the performance information shown in the Average Annual Total Return Table below is for the Fund's A class. The performance of the A class has not been adjusted to reflect the expenses of the IS class since the Institutional Shares are estimated to have a lower expense ratio than the expense ratio of the A class. In addition to Return Before Taxes, Return After Taxes is shown for A class to illustrate the effect of federal taxes on Fund returns. After-tax returns are shown only for the A class, and after-tax returns for the B, C and IS classes will differ from those shown for the A class. Actual after-tax returns depend on each investor's personal tax situation, and are likely to differ from those shown. After-tax returns are calculated using a standard set of assumptions. The stated returns assume the highest historical &lt;b&gt;federal&lt;/b&gt; income and capital gains tax rates. These after-tax returns do &lt;b&gt;not&lt;/b&gt; reflect the effect of any applicable &lt;b&gt;state&lt;/b&gt; and &lt;b&gt;local&lt;/b&gt; taxes. After-tax returns are not relevant to investors holding shares through a 401(k) plan, an Individual Retirement Plan or other tax-advantaged investment plan.&lt;br/&gt;&lt;br/&gt;(For the Period Ended December 31, 2011)</rr:PerformanceTableNarrativeTextBlock>
