The Fund is ordinarily exposed to over 30 emerging market&#13;countries at all times and typically invests in more than 500 stocks. &amp;#160;More than 25% of the Fund&amp;#146;s total assets may&#13;be denominated in any single currency. &amp;#160;The Fund may invest directly in foreign currencies. &amp;#160;The Fund may also invest&#13;in other pooled investment vehicles and may lend its securities.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 5.6pt 0"&gt;The Fund may engage in derivative transactions as a substitute&#13;for the purchase or sale of securities or currencies or to attempt to mitigate the adverse effects of foreign currency fluctuations.&#13;&amp;#160;Such transactions may include forward foreign currency exchange contracts, options and equity-linked securities (such as&#13;participation notes, equity swaps and zero strike calls and warrants). &amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 5.6pt 0"&gt;In managing the Fund, the portfolio managers seek to balance&#13;investment considerations and tax considerations and taking into account the taxes payable by shareholders in connection with distributions&#13;of investment income and net realized gains. &amp;#160;The Fund seeks to minimize income distributions and distributions of realized&#13;short-term gains that are taxed as ordinary income, as well as distributions of realized long-term gains (taxed as long-term capital&#13;gains). &amp;#160;The Fund seeks to employ a top-down, disciplined and structured investment process that emphasizes broad exposure&#13;and diversification among emerging market countries, economic sectors and issuers. &amp;#160;This rules-based strategy utilizes targeted&#13;allocation and systematic rebalancing to take advantage of certain quantitative and behavioral characteristics of emerging markets&#13;identified by the portfolio managers. &amp;#160;The portfolio managers select and allocate across countries based on factors such as&#13;size, liquidity, level of economic development, local economic diversification, and perceived risk and potential for growth. The&#13;Fund maintains a bias to broad inclusion; that is, the Fund intends to allocate its portfolio holdings to more emerging market&#13;countries rather than fewer emerging market countries. Relative to capitalization-weighted country indexes, individual country&#13;allocation targets emphasize the less represented emerging market countries and attempt to reduce concentration risks relative&#13;to a capitalization-weighted index. The Fund&amp;#146;s country allocations are rebalanced to their target weights if they exceed&#13;a pre-determined overweight. &amp;#160;This has the effect of reducing exposure to countries with strong relative performance and increasing&#13;exposure to countries which have underperformed. The frequency of rebalancing depends on the volatility and trading costs of the&#13;individual country. &amp;#160; Within each country, the Fund seeks to maintain exposure across key economic sectors, such as industrial/technology,&#13;consumer, utilities, basic industry/resource and financial. Relative to capitalization-weighted country indexes, the portfolio&#13;managers target weights to these sectors to emphasize the less represented sectors. The portfolio managers select individual securities&#13;as representatives of their economic sectors and generally weight them by their relative capitalization within that sector. &amp;#160;&lt;/p&gt;</rr:StrategyNarrativeTextBlock>

The Fund&amp;#146;s shares are sensitive&#13;to stock market volatility and the stocks in which the Fund invests may be more volatile than the stock market as a whole. &amp;#160;The&#13;prices of stocks may decline in response to conditions affecting the general economy; overall market changes; local, regional or&#13;global political, social or economic instability; and currency, interest rate and commodity price fluctuations, as well as issuer&#13;or sector specific events. &amp;#160;Market conditions may affect certain types of stocks to a greater extent than other types of stocks.&#13;&amp;#160;If the stock market declines, the value of Fund shares will also likely decline and, although stock values can rebound, there&#13;is no assurance that values will return to previous levels.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 5.6pt 0"&gt;Tax-Managed Investing Risk. &amp;#160;Market conditions may limit&#13;the Fund&amp;#146;s ability to generate tax losses or to generate dividend income taxed at favorable tax rates. The Fund&amp;#146;s tax-managed&#13;strategy may cause the Fund to hold a security in order to achieve more favorable tax-treatment or to sell a security in order&#13;to create tax losses. The Fund&amp;#146;s ability to utilize various tax-management techniques may be curtailed or eliminated in the&#13;future by tax legislation or regulation. &amp;#160;Tax code provisions applicable to tax-favored dividends are effective for taxable&#13;years beginning on or before December 31, 2012. &amp;#160; Thereafter, dividends will be taxable as ordinary income unless further&#13;legislative action is taken. &amp;#160; Although the Fund expects that a smaller portion of its total return will consist of taxable&#13;distributions to shareholders as compared to equity mutual funds that are managed without regard to tax considerations, there can&#13;be no assurance about the size of taxable distributions to shareholders.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 5.6pt 0"&gt;Foreign and Emerging Market Investment Risk.&lt;font style="font-family: Arial, Helvetica, Sans-Serif"&gt;&amp;#8194;&lt;/font&gt;Because&#13;the Fund invests a significant portion of its assets in foreign instruments, the value of Fund shares can be adversely affected&#13;by changes in currency exchange rates and political, economic and market developments abroad. &amp;#160;In emerging or less developed&#13;countries, these risks can be more significant. &amp;#160;Investment markets in emerging market countries are typically substantially&#13;smaller, less liquid and more volatile than the major markets in developed countries. &amp;#160;As a result, Fund share values may&#13;be more volatile than if the Fund invested only in developed markets. &amp;#160;Emerging market countries may have relatively unstable&#13;governments and economies. &amp;#160;Emerging market investments often are subject to speculative trading, which typically contributes&#13;to volatility. &amp;#160;Trading in foreign and emerging markets typically involves higher expense than trading in the United States.&#13;The Fund may have difficulties enforcing its legal or contractual rights in a foreign country. The value of investments denominated&#13;in foreign currencies can be adversely affected by changes in foreign currency exchange rates. Depositary receipts are subject&#13;to many of the risks associated with investing directly in foreign securities including political, economic and market risks.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 5.6pt 0"&gt;Small Company Equity Risk.&lt;font style="font-family: Arial, Helvetica, Sans-Serif"&gt;&amp;#8194;&lt;/font&gt;The&#13;stocks of small and emerging companies are generally subject to greater price fluctuations, limited liquidity, higher transaction&#13;costs and higher investment risk. &amp;#160;Small and emerging companies may have limited product lines, markets or financial resources,&#13;may be dependent on a limited management group, and may lack substantial capital reserves or an established performance record.&#13;&amp;#160;There may be generally less publicly available information about such companies than for larger, more established companies.&#13;Stocks of these companies frequently have lower trading volumes making them more volatile and potentially more difficult to value.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 5.6pt 0"&gt;Derivatives Risk. &lt;i&gt;&amp;#160;&lt;/i&gt;The use of derivatives can&#13;lead to losses because of adverse movements in the price or value of the asset, index, rate or instrument underlying a derivative,&#13;due to failure of a counterparty or due to tax or regulatory constraints. &amp;#160;Derivatives may create economic leverage in the&#13;Fund, which magnifies the Fund&amp;#146;s exposure to the underlying investment. Derivatives risk may be more significant when derivatives&#13;are used to enhance return or as a substitute for a cash investment position, rather than solely to hedge the risk of a position&#13;held by the Fund. &amp;#160;When derivatives are used to gain or limit exposure to a particular market or market segment, their performance&#13;may not correlate as expected to the performance of such market thereby causing the Fund to fail to achieve its original purpose&#13;for using such derivatives. A decision as to whether, when and how to use derivatives involves the exercise of specialized skill&#13;and judgment, and a transaction may be unsuccessful in whole or in part because of market behavior or unexpected events. &amp;#160;Derivative&#13;instruments may be difficult to value, may be illiquid, and may be subject to wide swings in valuation caused by changes in the&#13;value of the underlying instrument. &amp;#160;If a derivative&amp;#146;s counterparty is unable to honor its commitments, the value of&#13;Fund shares may decline and the Fund could experience delays in the return of collateral or other assets held by the counterparty.&#13;&amp;#160;The loss on derivative transactions may substantially exceed the initial investment.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 5.6pt 0"&gt;Securities Lending Risk. &amp;#160;Securities lending involves&#13;possible delay in recovery of the securities or possible loss of rights in the collateral should the borrower fail financially.&#13;As a result, the value of Fund shares may fall and there may be a delay in recovering the loaned securities. The value of Fund&#13;shares could also fall if a loan is called and the Fund is required to liquidate reinvested collateral at a loss or if the investment&#13;adviser is unable to reinvest cash collateral at rates that exceed the costs involved.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 5.6pt 0"&gt;Structured Management Risks. &amp;#160; The sub-adviser uses proprietary&#13;investment techniques and analyses in making investment decisions for the Fund , seeking to achieve its investment objective while&#13;minimizing exposure to market risk. &amp;#160;The strategy seeks to take advantage of certain quantitative and behavioral market characteristics&#13;identified by the sub-adviser , utilizing a rules-based country weighting process, a structured sector allocation methodology and&#13;a disciplined rebalancing model. &amp;#160;The Fund&amp;#146;s strategy has not been independently tested or validated, and there can&#13;be no assurance that it will achieve the desired results.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 5.6pt 0"&gt;General Fund Investing Risks. &amp;#160;The Fund is not a complete&#13;investment program and you may lose money by investing in the Fund. &amp;#160;All investments carry a certain amount of risk and there&#13;is no guarantee that the Fund will be able to achieve its investment objective. &amp;#160;Annual Fund Operating Expenses expressed&#13;as a percentage of the Fund&amp;#146;s average daily net assets may change as Fund assets increase and decrease, and Annual Fund Operating&#13;Expenses may differ in the future. &amp;#160;Purchase and redemption activities by Fund shareholders may impact the management of the&#13;Fund and its ability to achieve its investment objective. &amp;#160; In addition, the redemption by one or more large shareholders&#13;or groups of shareholders of their holdings in the Fund could have an adverse impact on the remaining shareholders in the Fund.&#13;&amp;#160; Investors in the Fund should have a long-term investment perspective and be able to tolerate potentially sharp declines&#13;in value. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance&#13;Corporation or any other government agency, entity or person. &amp;#160;Mutual funds, investment advisers, other market participants&#13;and many securities markets are subject to rules and regulations and the jurisdiction of one or more regulators.&amp;#160; Changes&#13;to applicable rules and regulations could have an adverse affect on securities markets and market participants, as well as on the&#13;Fund&amp;#146;s ability to execute its investment strategy.&lt;/p&gt;</rr:RiskNarrativeTextBlock>
