Although the Fund intends to invest substantially all of its assets in non-U.S. issuers under normal circumstances, the Fund may at times invest in U.S. issuers, particularly U.S. issuers whose growth prospects depend, in the Adviser&amp;#8217;s view, on non-U.S. factors. Under normal market conditions, the Fund invests significantly (at least 40%--unless market conditions are not deemed favorable by the Adviser) in securities of non-U.S. companies. In addition, the Fund invests, under normal circumstances, in the equity securities of companies located in at least three countries (and normally substantially more) other than the United States.&lt;br/&gt;&lt;br/&gt; In choosing investments, the Fund pursues an opportunistic investment strategy and is unconstrained by considerations of capitalization range, industry sector or country. The Fund may invest in any company in any type of industry (including real-estate related issuers) and in any type of equity security, listed or unlisted, with the potential for capital appreciation. The Fund may also invest in depositary receipts, rights and warrants, synthetic foreign equity securities, such as various types of warrants used internationally that entitle a holder to buy or sell underlying securities, and convertible securities.&lt;br/&gt;&lt;br/&gt; The Adviser employs a &amp;#8220;bottom up&amp;#8221; investment process that focuses on a company&amp;#8217;s prospective earnings growth, valuation and quality of management. The Fund does not target particular country or sector weightings. The percentage of the Fund&amp;#8217;s assets invested in securities of companies in a particular country or industry sector (or denominated in a particular currency) varies in accordance with the Adviser&amp;#8217;s assessment of the appreciation potential of such securities. The Fund may periodically invest in the securities of companies that are expected to appreciate due to a development particularly or uniquely applicable to that company, regardless of general business conditions or movements of the market as a whole. The Fund invests in both developed and emerging market countries.&lt;br/&gt;&lt;br/&gt; The Fund may make short sales of securities or may take short positions in securities in anticipation that the value of the securities will decline. The Fund may use total return swaps or other investment techniques to take such short positions. The Fund intends to make such investments when it believes that a company&amp;#8217;s securities are overvalued or face adverse economic or other conditions.&lt;br/&gt;&lt;br/&gt; The Fund may invest in established companies, but also in new and less-seasoned companies. The Fund&amp;#8217;s investments in companies with smaller capitalizations may offer more reward but may also entail greater risk than is generally true of larger, more established companies.&lt;br/&gt;&lt;br/&gt; When selecting securities, the Adviser typically looks for companies that have strong, experienced management teams and the potential to support greater than expected earnings growth rates. In making specific investment decisions for the Fund, the Adviser combines fundamental analysis and quantitative tools in its stock selection process.&lt;br/&gt;&lt;br/&gt; The Fund may, at times, invest in shares of ETFs in lieu of making direct investments in securities. ETFs may provide more efficient and economical exposure to the types of companies and geographic locations in which the Fund seeks to invest than direct investments.&lt;br/&gt;&lt;br/&gt; Currencies can have a dramatic impact on equity returns, significantly adding to returns in some years and greatly diminishing them in others. Currency and equity positions are evaluated separately. The Adviser may seek to hedge the currency exposure resulting from the Fund&amp;#8217;s securities positions when it finds the currency exposure unattractive. To hedge all or a portion of its currency risk, the Fund may from time to time invest in currency-related derivatives, including forward currency exchange contracts, futures, options on futures, swaps and options. The Adviser may also seek investment opportunities by taking long or short positions in currencies through the use of currency-related derivatives.&lt;br/&gt;&lt;br/&gt; The Fund may enter into other derivatives transactions, such as options, futures contracts, forwards, and swaps. The Fund may use options strategies involving the purchase and/or writing of various combinations of call and/or put options, including on individual securities and stock indexes, futures contracts (including futures contracts on individual securities and stock indexes) or shares of ETFs. These transactions may be used, for example, in an effort to earn extra income, to adjust exposure to individual securities or markets, or to protect all or a portion of the Fund&amp;#8217;s portfolio from a decline in value, sometimes within certain ranges.&lt;br/&gt;&lt;br/&gt; The Fund may use other investment techniques and may use leverage for investment purposes to increase return by using the cash made available by derivative instruments to make other investments in accordance with its investment objective.&lt;br/&gt;&lt;br/&gt; The Fund is non-diversified, meaning that it may invest more of its assets in a smaller number of issuers. &lt;/font&gt;</rr:StrategyNarrativeTextBlock>

Investments in real estate investment trusts, or "REITs", may have additional risks. REITs are dependent on the capability of their managers, may have limited diversification, and could be significantly affected by changes in tax laws.  &lt;/font&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li&gt;&lt;font style="DISPLAY: inline; FONT-SIZE: 12pt; FONT-FAMILY: Times New Roman"&gt;DIVERSIFICATION RISK: The Fund may have more risk because it is "non-diversified", meaning that it can invest more of its assets in a smaller number of issuers and that adverse changes in the value of one security could have a more significant effect on the Fund's NAV.  &lt;/font&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li&gt;&lt;font style="DISPLAY: inline; FONT-SIZE: 12pt; FONT-FAMILY: Times New Roman"&gt;SHORT SALES RISK: The Fund may not always be able to close out a short position on favorable terms. Short sales involve the risk that the Fund will incur a loss by subsequently buying a security at a higher price than the price at which it sold the security short. The amount of such loss is theoretically unlimited (since it is limited only by the increase in value of the security sold short by the Fund). In contrast, the risk of loss from a long position is limited to the Fund's investment in the long position, since its value cannot fall below zero. Short selling is a form of leverage. To mitigate leverage risk, the Fund will always hold liquid assets (including its long positions) at least equal to its short position exposure, marked-to-market daily.  &lt;/font&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li&gt;&lt;font style="DISPLAY: inline; FONT-SIZE: 12pt; FONT-FAMILY: Times New Roman"&gt;MANAGEMENT RISK: The Fund is subject to management risk because it is an actively managed investment fund.

Under normal circumstances, the Fund invests at least 80% of its net assets in equity securities of smaller companies. For these purposes, &amp;#8220;smaller companies&amp;#8221; are those that, at the time of investment, fall within the lowest 20% of the total U.S. equity market capitalization (excluding, for purposes of this calculation, companies with market capitalizations of less than $10 million). As of June 30, 2012, there were approximately 4,230 smaller companies, and those smaller companies had market capitalizations ranging up to approximately $9.3 billion. Because the Fund&amp;#8217;s definition of smaller companies is dynamic, the limits on market capitalization will change with the markets.&lt;br/&gt;&lt;br/&gt; The Fund may invest in any company and industry and in any type of equity security with potential for capital appreciation. It invests in well-known and established companies and in new and less-seasoned companies. The Fund&amp;#8217;s investment policies emphasize investments in companies that are demonstrating improving financial results and a favorable earnings outlook. The Fund may invest in foreign securities.&lt;br/&gt;&lt;br/&gt; When selecting securities, the Adviser typically looks for companies that have strong, experienced management teams, strong market positions, and the potential to support greater than expected earnings growth rates. In making specific investment decisions for the Fund, the Adviser combines fundamental and quantitative analysis in its stock selection process. The Fund may periodically invest in the securities of companies that are expected to appreciate due to a development particularly or uniquely applicable to that company regardless of general business conditions or movements of the market as a whole. Normally, the Fund invests in about 95-125 companies broadly diversified by sector. &lt;br/&gt;&lt;br/&gt; The Fund invests primarily in equity securities but may also invest in other types of securities, such as preferred stocks. The Fund may, at times, invest in shares of ETFs in lieu of making direct investments in securities.

The Fund may also invest up to 20% of its total assets in rights or warrants. &lt;br/&gt;&lt;br/&gt; The Fund may enter into derivatives transactions, such as options, futures contracts, forwards, and swaps. The Fund may use options strategies involving the purchase and/or writing of various combinations of call and/or put options, including on individual securities and stock indexes, futures contracts (including futures contracts on individual securities and stock indexes) or shares of ETFs. These transactions may be used, for example, in an effort to earn extra income, to adjust exposure to individual securities or markets, or to protect all or a portion of the Fund&amp;#8217;s portfolio from a decline in value, sometimes within certain ranges.&lt;/font&gt;</rr:StrategyNarrativeTextBlock>

Under normal circumstances, the Fund invests at least 80% of its net assets in equity securities issued by U.S. companies.&lt;br/&gt;&lt;br/&gt;The Adviser employs a combination of &amp;#8220;top-down&amp;#8221; and &amp;#8220;bottom-up&amp;#8221; investment processes with the goal of identifying the most attractive U.S. securities, fitting into broader investment themes identified by the Adviser, which are developments that have broad effects across industries and companies. Drawing on the global fundamental and quantitative research capabilities of the Adviser, and its economists&amp;#8217; macroeconomic insights, the Adviser seeks to identify long-term economic or business trends that will affect multiple industries. The Adviser will assess the effects of these trends, in the context of the business cycle, on entire industries and on individual companies. Through this process, the Adviser intends to identify key investment themes, which will be the focus of the Fund&amp;#8217;s investments and which are expected to change over time based on the Adviser&amp;#8217;s research.&lt;br/&gt;&lt;br/&gt;In addition to this &amp;#8220;top-down&amp;#8221; thematic approach, the Adviser will use a &amp;#8220;bottom-up&amp;#8221; analysis of individual companies that focuses on prospective earnings growth, valuation and quality of company management. The Adviser normally considers a universe of approximately 600 primarily U.S. mid- to large-capitalization companies for investment.&lt;br/&gt;&lt;br/&gt; The Fund invests in securities issued by companies from multiple industries in an attempt to maximize opportunity, which should also tend to reduce risk. The Fund may invest up to 20% of its net assets in equity and fixed-income securities issued by non-U.S. corporate and governmental issuers. The Fund may invest in both developed and emerging market countries. The percentage of the Fund&amp;#8217;s assets invested in securities of companies in a particular country or denominated in a particular currency varies in accordance with the Adviser&amp;#8217;s assessment of the appreciation potential of such securities. The Fund may invest in any company and industry and in any type of equity security, listed and unlisted, with potential for capital appreciation. It invests in well-known, established companies as well as new, smaller or less-seasoned companies. The Fund may also invest in synthetic foreign equity securities, which are a type of warrant used internationally that entitle a holder to buy or sell underlying securities, real estate investment trusts (&amp;#8220;REITs&amp;#8221;) and zero coupon bonds. Normally, the Fund invests in about 40-60 companies. &lt;br/&gt;&lt;br/&gt;The Fund may, at times, invest in shares of ETFs in lieu of making direct investments in securities. ETFs may provide more efficient and economical exposure to the types of companies and geographic locations in which the Fund seeks to invest than direct investments. &lt;br/&gt;&lt;br/&gt;Currencies can have a dramatic impact on equity returns, significantly adding to returns in some years and greatly diminishing them in others. Currency and equity positions are evaluated separately. The Adviser may seek to hedge the currency exposure resulting from securities positions when it finds the currency exposure unattractive. To hedge all or a portion of its currency risk, the Fund may, from time to time, invest in currency-related derivatives, including forward currency exchange contracts, futures, options on futures, swaps and options. The Adviser may also seek investment opportunities by taking long or short positions in currencies through the use of currency-related derivatives.&lt;br/&gt;&lt;br/&gt;The Fund may enter into other derivatives transactions, such as options, futures contracts, forwards, and swaps. The Fund may use options strategies involving the purchase and/or writing of various combinations of call and/or put options, including on individual securities and stock indexes, futures contracts (including futures contracts on individual securities and stock indexes) or shares of ETFs. These transactions may be used, for example, in an effort to earn extra income, to adjust exposure to individual securities or markets, or to protect all or a portion of the Fund&amp;#8217;s portfolio from a decline in value, sometimes within certain ranges.&lt;/font&gt;</rr:StrategyNarrativeTextBlock>

For  these purposes, &amp;#8220;small- and mid-capitalization companies&amp;#8221; are those that, at the time of investment, fall within the capitalization range between the smaller of $100 million or the market capitalization of the smallest company in the MSCI AC World SMID Index (ex-U.S.)(Net) and the greater of $13 billion or the market capitalization of the largest company in the MSCI AC World SMID Index (ex-U.S.)(Net).  The market capitalizations of companies in the MSCI AC World SMID Index (ex-U.S.)(Net) ranged from $22 million to $11.8 billion at June 30, 2012. Because the Fund&amp;#8217;s definition of small- and mid-capitalization companies is dynamic, the limits on market capitalization will change with the markets. Under normal market conditions, the Fund invests significantly (at least 40%--unless market conditions are not deemed favorable by the Adviser) in securities of non-U.S. companies. The Fund invests, under normal circumstances, in the equity securities of companies located in at least three countries (and normally substantially more) other than the United States. &lt;br/&gt;&lt;br/&gt;The Fund may invest in securities issued by non-U.S. companies in any industry sector and country. The Adviser employs a &amp;#8220;bottom-up&amp;#8221; investment process that focuses on a company&amp;#8217;s prospective earnings growth, valuation and quality of management. The Fund does not target particular country or sector weightings. The percentage of the Fund&amp;#8217;s assets invested in securities of companies in a particular country or industry sector (or denominated in a particular currency) varies in accordance with the Adviser&amp;#8217;s assessment of the appreciation potential of such securities. The Fund may periodically invest in the securities of companies  that are expected to appreciate due to a development particularly or uniquely applicable to that company, regardless of general business conditions or movements of the market as a whole. The Fund invests in both developed and emerging market countries and, at times, may invest significantly in emerging markets. &lt;br/&gt;&lt;br/&gt;The Fund may invest in any company and in any type of equity security, listed or unlisted, with the potential for capital appreciation. The Fund may also invest in synthetic foreign equity securities, which are various types of warrants used internationally that entitle a holder to buy or sell underlying securities. &lt;br/&gt;&lt;br/&gt;The Fund may invest in established companies and also in new and less-seasoned companies. The Fund&amp;#8217;s investments in companies with smaller capitalizations may offer more reward but may also entail greater risk than is generally true of larger, more established companies.&lt;br/&gt;&lt;br/&gt;When selecting securities, the Adviser typically looks for companies that have strong, experienced management teams and the potential to support greater than expected earnings growth rates. In making specific investment decisions for the Fund, the Adviser combines fundamental analysis and quantitative tools in its stock selection process. &lt;br/&gt;&lt;br/&gt;The Fund may, at times, invest in shares of ETFs in lieu of making direct investments in securities. ETFs may provide more efficient and economical exposure to the types of companies and geographic locations in which the Fund seeks to invest than direct investments.&lt;br/&gt;&lt;br/&gt; Currencies can have a dramatic impact on equity returns, significantly adding to returns in some years and greatly diminishing them in others.
