The adviser may allocate to the various asset classes either through the purchase of closed-end investment companies and exchange traded funds (&amp;#8220;ETFs&amp;#8221; and collectively, &amp;#8220;Underlying Funds&amp;#8221;) or through direct investment in the various securities. The adviser considers a number of factors when making these allocations, including fundamental and technical analysis to assess the relative risk and reward potential throughout the financial markets. As a result, the percentages allocated to equities, fixed income securities and cash and cash equivalents will vary. However, the adviser expects that, under normal circumstances, approximately 40%-80% of the Fund&amp;#8217;s assets will be allocated to equity related securities, without regard to market capitalization, style and sector. Fixed income related securities of any maturity and credit quality are expected to comprise, under normal circumstances, approximately 20%-60% of the Fund&amp;#8217;s investment portfolio, which may include investments in debt securities rated below investment grade. The Fund does not expect to directly invest in securities rated below B- by Moody&amp;#8217;s Investor Services, Inc., (commonly referred to as &amp;#8220;junk bonds&amp;#8221;), although it may invest in Underlying Funds that hold securities rated below B- or that are in default.&lt;br/&gt;&lt;br/&gt;To achieve exposure to the asset classes discussed above, the Fund will typically invest more than 50% of its assets in Underlying Funds. The remaining portion of the Fund&amp;#8217;s assets will be invested in individual equity and fixed income securities and alternative assets, such as real estate investment trusts (&amp;#8220;REITs&amp;#8221;), limited partnerships and structured securities, such as collateralized mortgage and debt obligations. REITs are companies that invest in real estate either directly or through mortgage securities. Collateralized mortgage obligations are securities that are backed by a pool of mortgage instruments and collateralized debt obligations are securities backed by a pool of bonds, debt or other assets. The Fund may invest directly in exchange-traded notes (&amp;#8220;ETNs&amp;#8221;), which are debt securities whose returns are linked to a particular index. The Fund may also invest in structured notes, which are debt securities whose returns are linked to the performance of a single equity security, a basket of equity securities, or an equity index. &lt;br/&gt;&lt;br/&gt;The Fund also may invest directly in the equity and debt securities of U.S. corporate issuers, and U.S. Government securities. Equity securities purchased by the Fund may include, but are not limited to, common stocks, preferred stocks, convertible securities, and warrants to buy common stocks. In addition, the Fund may invest without limitation in foreign securities, including securities issued in emerging market countries, either directly or by purchasing American Depositary Receipts (&amp;#8220;ADRs&amp;#8221;). The Fund may also invest in Underlying Funds and other investment companies that hold foreign securities or ADRs. The Fund may also seek to realize additional gains or hedge investments by selling a security short. When the Fund engages in a short sale, it sells a security it does not own and, to complete the sale, borrows the same security from a broker or other institution. The Fund may liquidate positions in order to change the Fund&amp;#8217;s asset allocation or to generate cash to invest in more attractive opportunities, which may result in a larger portion of any net gains being realized as short-term capital gains. In addition, a negative change in the fundamental or qualitative characteristics of the issuer may cause the adviser to sell a security. Finally, the adviser may sell a security when its price approaches, meets or exceeds the adviser&amp;#8217;s target price. &lt;br/&gt;&lt;br/&gt;The Fund may invest without limitation in interest rate, index, total return, currency and credit default swap agreements. A swap is an agreement between two parties (known as counterparties) where one stream of payments is exchanged for another based on a specified principal amount. Swaps are typically used to limit or manage exposure to fluctuations in interest rates, currency exchange rates or potential defaults by credit issuers. The Fund may attempt to enhance the return on the cash portion of its portfolio by investing in a total return swap agreement. A total return swap agreement provides the Fund with a return based on the performance of an underlying asset, in exchange for fee payments to a counterparty based on a specific rate. The difference in the value of these income streams is recorded daily by the Fund, and is settled in cash at the end of each month. If the underlying asset declines in value over the term of the swap, the Fund would be required to pay the dollar value of that decline to the counterparty. The Fund may use its own net asset value as the underlying asset in a total return swap. The adviser utilizes a total return swap using the Fund&amp;#8217;s return as the underlying asset in order for the Fund&amp;#8217;s cash positions allocated to the swap to share in similar investment returns at the Fund itself while maintaining a sufficient cash position to meet liquidity needs in the Fund, including liquidity to invest in new investment opportunities.</rr:StrategyNarrativeTextBlock>
  <rr:RiskHeading contextRef="Duration_02Feb2012_01Feb2013S000013779_Member">&lt;b&gt;Principal Risks &lt;/b&gt;</rr:RiskHeading>
  <rr:RiskNarrativeTextBlock contextRef="Duration_02Feb2012_01Feb2013S000013779_Member">&lt;b&gt;All mutual funds carry a certain amount of risk. The Fund&amp;#8217;s returns will vary and you could lose money on your investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the FDIC or any other government agency. Below are some specific risks of investing in the Fund. &lt;/b&gt;&lt;br/&gt;&lt;br/&gt;Underlying Fund Risk. The Fund will incur higher and duplicative expenses when it invests in money market funds, ETFs, closed-end funds, and other investment companies. There is also the risk that the Fund may suffer losses due to the investment practices of the Underlying Funds (such as the use of derivatives). The Underlying Funds in which the Fund invests may not be able to replicate exactly the performance of the indices they track, due to transactions costs and other expenses of the Underlying Funds. The shares of closed-end funds frequently trade at a discount to their net asset value. There can be no assurance that the market discount on shares of any closed-end fund purchased by the Fund will ever decrease, and it is possible that the discount may increase. &lt;br/&gt;&lt;br/&gt;Convertible Security Risk. The market value of convertible securities and other debt securities tends to fall when prevailing interest rates rise. The value of convertible securities also tends to change whenever the market value of the underlying common or preferred stock fluctuates. &lt;br/&gt;&lt;br/&gt;Emerging Markets Risk. In addition to all the risk associated with Foreign Investment Risk discussed below, countries with emerging markets may have relatively unstable governments, social, financial and legal systems that do not protect shareholders, economies based on only a few industries, and inefficient securities markets. &lt;br/&gt;&lt;br/&gt;Exchange-Traded Note Risk. The Fund may invest in ETNs, which are notes representing unsecured debt of the issuer. ETNs are typically linked to the performance of an index plus a specified rate of interest that could be earned on cash collateral. The value of an ETN may be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying markets, changes in the applicable interest rates, changes in the issuer&amp;#8217;s credit rating and economic, legal, political or geographic events that affect the referenced index. There may be restrictions on the Fund&amp;#8217;s right to redeem its investment in an ETN, and there may be limited availability of a secondary market. &lt;br/&gt;&lt;br/&gt;Fixed Income Risk. The Fund may invest directly or indirectly through Underlying Funds that invest in fixed income securities, including high yield securities, also known as &amp;#8220;junk bonds.&amp;#8221; Fixed income securities increase or decrease in value based on changes in interest rates. If rates increase, the value of the Fund&amp;#8217;s fixed income securities generally declines. On the other hand, if rates fall, the value of the fixed income securities generally increases. Junk bonds provide greater income and opportunity for gain, but entail greater risk of loss of principal. The issuer of a fixed income security may not be able to make interest and principal payments when due. With regard to junk bond issuers, the issuer&amp;#8217;s capacity to pay interest and repay principal in accordance with the terms of the obligation may be more at risk. &lt;br/&gt;&lt;br/&gt;Foreign Investing Risk. Investments in foreign securities may be affected by currency controls and exchange rates; different accounting, auditing, financial reporting, and legal standards and practices; expropriation; changes in tax policy; greater market volatility; differing securities market structures; higher transaction costs; and various administrative difficulties, such as delays in clearing and settling portfolio transactions or in receiving payment of dividends. These risks may be heightened in connection with investments in emerging or developing countries. &lt;br/&gt;&lt;br/&gt;Management Risk. The adviser&amp;#8217;s judgments about the attractiveness, value and potential appreciation of a particular asset class or individual security in which the Fund invests may prove to be incorrect and there is no guarantee that the adviser&amp;#8217;s judgment will produce the desired results. &lt;br/&gt;&lt;br/&gt;Market Risk. Overall stock market risks may also affect the value of the Fund. Factors such as domestic economic growth and market conditions, interest rate levels and political events affect the securities markets. &lt;br/&gt;&lt;br/&gt;REIT Risk. The value of Equity REITs may be affected by changes in the value of the underlying property owned by the REITs, while the value of mortgage REITs may be affected by the quality of any credit extended. Investment in REITs involves risks similar to those associated with investing in small capitalization companies, and REITs (especially mortgage REITs) are subject to interest rate risks. Because REITs incur expenses like management fees, investments in REITs also add an additional layer of expenses. &lt;br/&gt;&lt;br/&gt;Security Risk. The value of the Fund may decrease in response to the activities and financial prospects of individual securities in the Fund&amp;#8217;s portfolio. &lt;br/&gt;&lt;br/&gt;Short Sale Risk. Positions in shorted securities are speculative and more risky than long positions (purchases) in securities. Short selling will also result in higher transaction costs (such as interest and dividends), and may result in higher taxes, which reduce the Fund&amp;#8217;s return. Generally the short sales in which the Fund may invest will not be &amp;#8220;against the box,&amp;#8221; meaning the Fund will not own the shorted security, so theoretically the potential loss resulting from short sales is unlimited. &lt;br/&gt;&lt;br/&gt;Smaller Company Risk. Smaller companies, typically those with market capitalizations of $1 billion or less, involve greater risk of loss and price fluctuation than larger companies. Their securities may also be less liquid and more volatile. As a result, the Fund could have greater difficulty buying or selling a security of a small-cap issuer at an acceptable price, especially in periods of market volatility. &lt;br/&gt;&lt;br/&gt;Structured Notes Risk. Structured notes are subject to a number of fixed income risks including general market risk, interest rate risk, and the risk that the issuer on the note may fail to make interest and/or principal payments when due, or may default on its obligations entirely. In addition, as a result of the imbedded derivative features, structured notes generally are subject to more risk than investing in a simple note or bond issued by the same issuer. &lt;br/&gt;&lt;br/&gt;Swap Risk. The Fund may invest in interest rate, index, total return, currency and credit default swap agreements. The degree to which the Fund may invest in these instruments is not limited. All of these agreements are considered derivatives. Swaps could result in losses if interest or foreign currency exchange rates or credit quality changes are not correctly anticipated by the adviser. Total return swaps could result in losses if the reference index, security, or investments do not perform as anticipated. Credit default swaps can increase Fund exposure to credit risk and could result in losses if the adviser does not correctly evaluate the creditworthiness of the company or government on which the credit default swap is based. The use of swaps may not always be successful; using them could lower the Fund&amp;#8217;s total return, their prices can be highly volatile, and the potential loss from the use of swaps can exceed a Fund&amp;#8217;s initial investment in such instruments. Also, the other party to a swap agreement could default on its obligations or refuse to cash out a Fund&amp;#8217;s investment at a reasonable price, which could turn an expected gain into a loss.</rr:RiskNarrativeTextBlock>

  <rr:StrategyNarrativeTextBlock contextRef="Duration_02Feb2012_01Feb2013S000037672_Member">The Fund&amp;#8217;s adviser allocates the Fund&amp;#8217;s assets among two principal strategies: a Tactical Closed-End Fund Equity strategy and a Dividend Focus strategy. The amount allocated to each of the principal strategies may change depending on the adviser&amp;#8217;s assessment of market risk, security valuations, market volatility, and the prospects for earning income and total return. The adviser determines which portion of the Fund&amp;#8217;s assets are allocated to each strategy based on market conditions, although there is no set minimum for any strategy. Therefore, the amount allocated to any individual strategy may be between 0% and 100%. However, the adviser anticipates it will, under normal circumstances, allocate some portion of the Fund&amp;#8217;s assets to each of the two strategies at any given time. The adviser manages the Tactical Closed-End Fund Equity strategy. The sub-adviser manages the Dividend Focus strategy. &lt;br /&gt;&lt;br /&gt; Under normal circumstances, the Fund will invest at least 80% of its net assets plus any borrowings for investment purposes in dividend paying securities, including common stocks, preferred stock, shares of closed-end funds, shares of exchange-traded funds and shares of other investment companies. The adviser&amp;#8217;s and sub-adviser&amp;#8217;s security selection process is described below. The adviser or sub-adviser may liquidate positions in order to implement a change in the adviser&amp;#8217;s overall asset allocation or to generate cash to invest in more attractive opportunities. This may result in a larger portion of any net gains in the Fund being realized as short-term capital gains. In addition, the adviser, or sub-adviser may sell a security if there is a negative change in the fundamental or qualitative characteristics of the issuer or when its price approaches, meets or exceeds the target price established by the adviser or sub-adviser, as applicable. &lt;br /&gt;&lt;br /&gt; The sub-adviser will generally select those securities it deems appropriate for the Fund&amp;#8217;s portfolio once annually. The securities are monitored on an ongoing basis, but absent some significant event, the securities are held until the portfolio is reconstituted and a new portfolio of securities is selected for the next year. The sub-adviser&amp;#8217;s quantitative investment approach relies on financial models and computer databases rather than analysis of the fundamentals of each stock to identify securities for inclusion in the Fund. In selecting securities for the Fund, the sub-adviser seeks to identify stocks of companies that meet the following investment criteria at the time of purchase: attractive free cash flow yield, dividend yield at least equal to that of the broad equity market, and low probability of experiencing financial distress. &lt;br /&gt;&lt;br/&gt; Tactical ClosedH-End Fund Equity Strategy &lt;br /&gt; In implementing the Fund&amp;#8217;s Tactical Closed-End Fund Equity strategy, the adviser allocates that portion of the Fund&amp;#8217;s investments among closed-end investment companies (and to a lesser degree in exchange traded funds (&amp;#8220;ETFs&amp;#8221; and collectively, &amp;#8220;Underlying Funds&amp;#8221;)) that invest primarily in domestic and international equities (including those issued in emerging markets), equity options and in securities convertible into equity securities and preferred equities. Some closed-end funds may invest in a mix of these and other underlying securities (including fixed income securities) and are referred to as hybrid closed-end funds. The Underlying Funds and the Fund itself may also invest in cash or cash equivalents. Allocations to asset classes, investment vehicles, sectors and countries are made based on the research and judgment of the adviser. The adviser considers a number of factors when selecting Underlying Funds, including fundamental and technical analysis to assess the relative risk and reward potential throughout the financial markets. The adviser may also allocate the Fund&amp;#8217;s assets among cash and short term investments. The term &amp;#8220;tactical&amp;#8221; is used to indicate that the portion of the Fund&amp;#8217;s assets allocated to this strategy will invest in closed-end funds to take advantage of pricing discrepancies in the closed-end fund market. At times the adviser may actively trade the Fund&amp;#8217;s holdings to take advantage of these pricing discrepancies. &lt;br /&gt;&lt;br /&gt; In selecting closed-end funds, in particular, the adviser will opportunistically utilize a combination of short-term and longer-term trading strategies to seek to derive value from discount and premium spreads associated with closed-end funds. The adviser may choose from different types of closed-end funds including business development companies. The adviser performs both a quantitative and qualitative analysis of closed-end funds prior to any closed-end fund being added to the Fund&amp;#8217;s portfolio. This analysis and the adviser&amp;#8217;s screening models and computer trading programs help determine when to buy and sell the closed-end funds in the Fund&amp;#8217;s portfolio. If the Fund invests in affiliated closed-end funds, the Fund will only do so in accordance with the provisions of the Investment Company Act of 1940. The adviser may also be required to waive certain fees in the event the Fund invests in affiliated closed-end funds. &lt;br /&gt;&lt;br /&gt; An ETF is an investment company that seeks to track the performance of a particular market index. These indices include not only broad-market indices, but more specific indices as well, including those relating to particular sectors, markets, regions and industries. &lt;br /&gt;&lt;br /&gt; The Fund may also invest in actively managed ETFs and those ETFs utilizing leverage to attempt to outperform a stated benchmark. ETFs will be selected based on their ability to offer specific asset class, sector and style exposure in a cost and tax efficient manner. The Fund purchases ETF shares on the secondary market. Unlike a mutual fund that allocates its assets among other mutual funds based on the perceived ability of the advisers to those mutual funds, the Fund&amp;#8217;s adviser actively manages the Fund&amp;#8217;s portfolio among the Underlying Funds based on the adviser&amp;#8217;s research and analysis of the market and the investment merit of the Underlying Funds themselves. &lt;br /&gt;&lt;br /&gt; The Fund also may invest directly in the equity and debt securities of U.S. corporate issuers, and U.S. Government securities. Equity securities purchased by the Fund may include, but are not limited to, common stocks, preferred stocks, convertible securities, and warrants to buy common stocks. In addition, the Fund may invest without limitation in foreign securities, including securities issued in emerging market countries, either directly or by purchasing American Depositary Receipts (ADRs). The Fund may also invest in Underlying Funds and other investment companies that hold foreign securities or ADRs. &lt;br /&gt;&lt;br /&gt; The Fund may enter into total return swaps. Total return swaps are agreements that provide the Fund with a return based on the performance of an underlying asset, in exchange for fee payments to a counterparty based on a specific rate of return. The difference in the value of these income streams is recorded daily by the Fund, and is settled in cash at the end of each month. The fee paid by the Fund will typically be determined by multiplying the face value of the swap agreement by an agreed upon interest rate. In addition, if the underlying asset declines in value over the term of the swap, the Fund would also be required to pay the dollar value of that decline to the counterparty. Total return swaps could result in losses if the underlying asset does not perform as anticipated by the adviser. The Fund may use its own net asset value as the underlying asset in a total return swap. This strategy serves to reduce &amp;#8220;cash drag&amp;#8221; (the impact of uninvested cash on the Fund&amp;#8217;s overall return) by replacing it with the total return of the Fund&amp;#8217;s own investment holdings. The Fund records fluctuations in the value of open swap contracts on a daily basis as unrealized gains or losses. The Fund may also borrow money in order to pay redemption requests rather than sell securities at an inopportune time. &lt;br /&gt;&lt;br/&gt; Dividend Focus Strategy &lt;br /&gt; In implementing the Fund&amp;#8217;s Dividend Focus Strategy, the sub-adviser will, under normal circumstances, invest the Fund&amp;#8217;s assets in dividend-paying common stocks. The sub-adviser will invest primarily in the common stocks of mid to large capitalization companies (generally companies with market capitalizations of more than $2 billion at the time of purchase). The sub-adviser seeks to identify stocks of companies trading primarily on U.S. stock exchanges in an effort to construct a portfolio of companies that provides competitive returns consistent with the broad equity market while also providing a level of capital protection during market downturns. The sub-adviser uses a quantitative approach in managing the portfolio, and it rebalances that portion of the Fund&amp;#8217;s portfolio allocated to the sub-adviser annually. &lt;br /&gt;&lt;br /&gt; Although stocks may be added to or deleted from the Fund&amp;#8217;s portfolio at any time during the year, the sub-adviser expects that modifications to the Fund&amp;#8217;s portfolio will primarily take place once a year during the sub-adviser&amp;#8217;s annual portfolio review and rebalancing. A quantitative investment approach relies on financial models and computer databases rather than analysis of the fundamentals of each stock to identify securities for inclusion &lt;br /&gt;&lt;br /&gt; In selecting the securities for the Fund, the sub-adviser seeks to identify stocks of companies that meet the following investment criteria at the time of purchase: &lt;ul&gt;&lt;li type = "square"&gt; attractive free cash flow yield (i.e., cash generated by a company that is available to equity holders). Minimum free cash flow yield must exceed the yield of high quality corporate bonds,&lt;/li&gt;&lt;li type = "square"&gt; dividend yield at least equal to that of the broad equity market, and&lt;/li&gt;&lt;li type = "square"&gt; low probability of experiencing financial distress. This estimate is based on a credit scoring model that incorporates measures of corporate health such as liquidity, profitability, leverage, and solvency to assess the likelihood of a bankruptcy in the next one to two years&lt;/li&gt;&lt;/ul&gt;The sub-adviser&amp;#8217;s strategy may involve allocating large portions of the Fund&amp;#8217;s holdings to industry sectors which meet the sub-adviser&amp;#8217;s investment criteria. &lt;br /&gt;&lt;br /&gt; The sub-adviser may invest in stocks of U.S. and foreign companies, including those in emerging markets, as well as ADRs. &lt;br /&gt;&lt;br /&gt; On an annual basis, the sub-advisor reviews the Fund&amp;#8217;s portfolio holdings against the investment criteria set forth above, and will sell those holdings that no longer meet such criteria.</rr:StrategyNarrativeTextBlock>
  <rr:RiskNarrativeTextBlock contextRef="Duration_02Feb2012_01Feb2013S000037672_Member">&lt;b&gt;The Fund&amp;#8217;s returns will vary and you could lose money on your investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the FDIC or any other government agency. Below is a summary of the principal risks of investing in the Fund. &lt;/b&gt;&lt;br /&gt;&lt;br /&gt; Convertible Security Risk. The market value of convertible securities and other debt securities tends to fall when prevailing interest rates rise. The value of convertible securities also tends to change whenever the market value of the underlying common or preferred stock fluctuates. &lt;br /&gt;&lt;br /&gt; Currency Risk. To the extent that the Fund invests in securities denominated in, and/or receiving revenues in, foreign currencies, it will be subject to currency risk. This is the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency hedged. In either event, the dollar value of an investment in the Fund would be adversely affected. Currencies in non-U.S. countries may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates, intervention by U.S. or foreign governments, central banks or supranational agencies, such as the International Monetary Fund, or by the imposition of currency controls or other political developments in the United States or abroad. &lt;br /&gt;&lt;br /&gt; Emerging Markets Risk. Countries with emerging markets may have relatively unstable governments, social and legal systems that do not protect shareholders, economies based on only a few industries, and inefficient securities markets. &lt;br /&gt;&lt;br /&gt; Equity Risk. The prices of equity securities rise and fall daily. These price movements may result from factors affecting individual companies, industries or the securities market as a whole. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. In addition, the equity market tends to move in cycles which may cause stock prices to fall over short or extended periods of time. &lt;br /&gt;&lt;br /&gt; Fixed Income Risk. The Fund may invest directly or indirectly through Underlying Funds that invest in fixed income securities, including high yield junk bonds. Fixed income securities increase or decrease in value based on changes in interest rates. If interest rates increase, the value of the Fund&amp;#8217;s fixed income securities generally declines. On the other hand, if interest rates fall, the value of the fixed income securities generally increases. Junk bonds provide greater income and opportunity for gain, but entail greater risk of loss of principal. The issuer of a fixed income security may not be able to make interest and principal payments when due. With regard to junk bond issuers, the issuer&amp;#8217;s capacity to pay interest and repay principal in accordance with the terms of the obligation may be more at risk. Some of the related risks of fixed income securities include: &lt;ul&gt;&lt;li type ="square"&gt; Credit Risk. The issuer of a fixed income security may not be able to make interest and principal payments when due.&lt;/li&gt;&lt;li type ="square"&gt; High Yield Securities/Junk Bond Risk. The Fund may invest in Underlying Funds that invest in high yield securities, also known as &amp;#8220;junk bonds.&amp;#8221; High yield securities provide greater income and opportunity for gain, but entail greater risk of loss of principal.&lt;/li&gt;&lt;li type ="square"&gt; Government Risk. The U.S. Government&amp;#8217;s guarantee of ultimate payment of principal and timely payment of interest on certain U. S. Government securities owned by the Fund does not imply that the Fund&amp;#8217;s shares are guaranteed or that the price of the Fund&amp;#8217;s shares will not fluctuate.&lt;/li&gt;&lt;li type ="square"&gt; Interest Rate Risk. The Fund&amp;#8217;s share price and total return will vary in response to changes in interest rates. If rates increase, the value of the Fund&amp;#8217;s investments generally will decline, as will the value of your investment in the Fund. Securities with longer maturities tend to produce higher yields, but are more sensitive to changes in interest rates and are subject to greater fluctuations in value.&lt;/li&gt;&lt;li type ="square"&gt; Sovereign Obligation Risk. The Underlying Funds may invest in sovereign debt obligations. The issuer of the sovereign debt or the governmental authorities that control the repayment of the debt may be unable or unwilling to repay principal or interest when due, and the Underlying Funds may have limited recourse in the event of a default.&lt;/li&gt;&lt;/ul&gt; Foreign Investing Risk. Investments in foreign securities may be affected by currency controls and exchange rates, different accounting, auditing, financial reporting, and legal standards and practices; expropriation; changes in tax policy; greater market volatility; differing securities market structures; higher transaction costs; and various administrative difficulties, such as delays in clearing and settling portfolio transactions or in receiving payment of dividends. These risks may be heightened in connection with investments in emerging or developing countries. &lt;br /&gt;&lt;br /&gt; Investment Style Risk. The Fund is managed by allocating the Fund&amp;#8217;s assets to two different strategies, investing in closed-end funds and investing in dividend paying common stocks. This may cause the Fund to underperform funds that do not limit their investments to these two strategies during periods when closed-end funds or dividend paying stocks underperform other types of investments. The sub-adviser&amp;#8217;s strategy involves a long-term buy and hold strategy. Because of this strategy, the Fund may forego the opportunity to buy or sell securities at their most attractive price. &lt;br /&gt;&lt;br /&gt; Large- and Mid-Cap Risk. Both large-and mid-cap stocks tend to go in and out of favor based on market and economic conditions. However, stocks of mid-cap companies tend to be more volatile than those of large cap companies because mid-cap companies tend to be more susceptible to adverse business or economic events than larger more established companies. &lt;br /&gt;&lt;br /&gt; Management Risk. The adviser&amp;#8217;s and sub-adviser&amp;#8217;s judgments about the attractiveness, value and potential appreciation of a particular asset class or individual security in which the Fund invests may prove to be incorrect and there is no guarantee that the adviser&amp;#8217;s or sub-adviser&amp;#8217;s judgments will produce the desired results. &lt;br /&gt;&lt;br /&gt; Market Risk. Overall stock market risks may also affect the value of the Fund. Factors such as domestic economic growth and market conditions, interest rate levels, and political events affect the securities markets. &lt;br /&gt;&lt;br /&gt; Portfolio Turnover Risk. The Fund may engage in short-term trading to try to achieve its objective and may have portfolio turnover rates in excess of 100%. Increased portfolio turnover may cause the Fund to incur higher brokerage costs, which may adversely affect the Fund&amp;#8217;s performance, and may produce increased taxable distributions. &lt;br /&gt; Preferred Stock Risks. Preferred stock represents the senior residual interest in the assets of an issuer after meeting all claims, with priority to corporate income and liquidation payments over the issuer&amp;#8217;s common stock. As such, preferred stock is inherently more risky than the bonds and other debt instruments of the issuer, but less risky than its common stock. There is no assurance that dividends on preferred stocks in which the Fund invests will be declared or otherwise made payable. When interest rates fall below the rate payable on an issue of preferred stock or for other reasons, the issuer may redeem the preferred stock, generally after an initial period of call protection in which the stock is not redeemable. Preferred stocks may be significantly less liquid than many other securities, such as U.S. Government securities, corporate debt and common stock. &lt;br /&gt;&lt;br /&gt; Security Risk. The value of the Fund may decrease in response to the activities and financial prospects of individual securities in the Fund&amp;#8217;s portfolio. &lt;br /&gt;&lt;br /&gt; Smaller Company Risk. The Fund may invest in smaller capitalization companies (that is, companies with market capitalizations of $1 billion or less). The earnings and prospects of smaller companies are more volatile than those of larger companies. Smaller companies also may experience higher failure rates than do larger companies. In addition, the securities of smaller companies may trade less frequently and in smaller volumes than the securities of larger companies, which may disproportionately affect their market price, tending to make them fall more in response to selling pressure than is the case with larger companies. Finally, smaller companies may have limited markets, product lines or financial resources and may lack management experience. &lt;br /&gt;&lt;br /&gt; Swap Risk. The Fund may invest in total return swap agreements. The degree to which the Fund may invest in these instruments is not limited. These agreements are considered derivatives. Total return swaps could result in losses if the reference index, security, or investments do not perform as anticipated. The use of swaps may not always be successful; using them could lower Fund total return, their prices can be highly volatile, and the potential loss from the use of swaps can exceed a Fund&amp;#8217;s initial investment in such instruments. Also, the other party to a swap agreement could default on its obligations or refuse to cash out a Fund&amp;#8217;s investment at a reasonable price, which could turn an expected gain into a loss. &lt;br /&gt;&lt;br /&gt; Tax Risk. With respect to federal income taxes, any distributions to shareholders that represent income from taxable securities will generally be taxable as ordinary income, while other distributions, such as capital gains, are taxable to the same extent they would be for any mutual fund. Distributions also are generally subject to state taxes with certain exceptions (e.g. some states may have an exception where a portion of the fund&amp;#8217;s income is attributable to municipal securities issued in the state in which you reside). New federal or state governmental action could adversely affect the tax-exempt status of securities held by the fund, resulting in higher tax liability for shareholders and potentially hurting fund performance as well. Beginning in 2013, the maximum federal tax rate for qualified dividend income is scheduled to increase from 15% to over 39%, absent legislative action. &lt;br /&gt;&lt;br /&gt; Underlying Fund Risk. The Fund will incur higher and duplicative expenses when it invests in Underlying Funds. There is also the risk that the Fund may suffer losses due to the investment practices of the Underlying Funds (such as the use of derivatives). The Fund may also invest in Underlying Funds that are actively managed, or utilize leverage in their portfolios. The ETFs in which the Fund invests may not be able to replicate exactly the performance of the indices they track, due to transactions costs and other expenses of the ETFs. The shares of closed-end funds frequently trade at a discount to their net asset value. There can be no assurance that the market discount on shares of any closed-end fund purchased by the Fund will ever decrease, and it is possible that the discount may increase. The Fund may invest in closed-end funds that elect to be treated as Business Development Companies (BDCs), which may be subject to a high degree of risk. BDCs typically invest in small and medium-sized private and certain public companies that may not have access to public equity markets for raising capital.</rr:RiskNarrativeTextBlock>

  <rr:StrategyNarrativeTextBlock contextRef="Duration_02Feb2012_01Feb2013S000030798_Member">The Fund&amp;#8217;s adviser, after consultation with the sub-adviser, allocates the Fund&amp;#8217;s assets among three principal strategies: Tactical Closed-end Fund Income strategy, Core Fixed Income strategy, and Opportunistic Income strategy. The amount allocated to each of the principal strategies may change depending on the adviser&amp;#8217;s assessment of market risk, security valuations, market volatility, and the prospects for earning income and total return. The adviser determines which portion of the Fund&amp;#8217;s assets are allocated to each strategy based on market conditions, although there is no set minimum for any strategy. Therefore, the amount allocated to any individual strategy may be between 0% and 100%. However, the adviser anticipates it will, under normal circumstances, allocate some portion of the Fund&amp;#8217;s assets to each of the three strategies at any given time. The adviser manages the Tactical Closed-end Fund Income strategy. The sub-adviser manages the Core Fixed Income and Opportunistic Income strategies. &lt;br /&gt;&lt;br /&gt; The adviser&amp;#8217;s and sub-adviser&amp;#8217;s security selection process is described below. The adviser or sub-adviser may liquidate positions in order to implement a change in the adviser&amp;#8217;s overall asset allocation or to generate cash to invest in more attractive opportunities. This may result in a larger portion of any net gains in the Fund being realized as short-term capital gains. In addition, the adviser, or sub-adviser may sell a security if there is a negative change in the fundamental or qualitative characteristics of the issuer or when its price approaches, meets or exceeds the target price established by the adviser or sub-adviser, as applicable. &lt;br /&gt;&lt;br /&gt; Tactical Closed-end Fund Income Strategy &lt;br /&gt;In implementing the Fund&amp;#8217;s Tactical Closed-end Fund Income strategy, the adviser allocates that portion of the Fund&amp;#8217;s investments among closed-end investment companies and exchange traded funds (&amp;#8220;ETFs&amp;#8221; and collectively, &amp;#8220;Underlying Funds&amp;#8221;) that invest primarily in income producing securities. The adviser considers a number of factors when selecting Underlying Funds, including fundamental and technical analysis to assess the relative risk and reward potential throughout the financial markets. The adviser may also allocate the Fund&amp;#8217;s assets among cash and short term investments. The term &amp;#8220;tactical&amp;#8221; is used to indicate that the portion of the Fund&amp;#8217;s assets allocated to this strategy will invest in closed-end funds to take advantage of pricing discrepancies in the closed-end fund market. &lt;br /&gt;&lt;br /&gt; In selecting closed-end funds, in particular, the adviser will opportunistically utilize a combination of short-term and longer-term trading strategies to seek to derive value from discount and premium spreads associated with closed-end funds. The adviser performs both a quantitative and qualitative analysis of closed-end funds prior to any closed-end fund being added to the Fund&amp;#8217;s portfolio. This analysis and the adviser&amp;#8217;s screening models and computer trading programs help determine when to buy and sell the closed-end funds in the Fund&amp;#8217;s portfolio. If the Fund invests in affiliated closed-end funds, the Fund will only do so in accordance with the provisions of the Investment Company Act of 1940. The adviser may also be required to waive certain fees in the event the Fund invests in affiliated closed-end funds. &lt;br /&gt;&lt;br /&gt; The Underlying Funds in which the adviser invests generally focus on a broad range of fixed income strategies or sectors. The Underlying Funds may also invest in convertible securities, preferred securities, high yield securities, dividend strategies, covered call option strategies, real estate, energy, utility and other income-oriented strategies. Fixed income securities include exchange-traded notes (&amp;#8220;ETNs&amp;#8221;), which are debt securities whose returns are linked to a particular index. Fixed income securities may also include structured notes, which are debt securities whose returns are linked to the performance of a single equity security, a basket of equity securities, or an equity index. The Fund may invest in Underlying Funds that invest in securities rated below B- by Moody&amp;#8217;s Investor Services, Inc., (commonly referred to as &amp;#8220;junk bonds&amp;#8221;) or that are in default. Junk bonds provide greater income and opportunity for gain, but entail greater risk of loss of principal. The issuer of a fixed income security may not be able to make interest and principal payments when due. With regard to junk bond issuers, the issuer&amp;#8217;s capacity to pay interest and repay principal in accordance with the terms of the obligation may be more at risk. &lt;br /&gt;&lt;br /&gt; The adviser may invest the Tactical Closed-end Fund income assets, without limitation, in interest rate, index, total return and currency swap agreements. A swap is an agreement between two parties (known as counterparties) where one stream of payments is exchanged for another based on a specified principal amount. Swaps are typically used to gain, limit or manage exposure to fluctuations in interest rates, currency exchange rates or potential defaults by credit issuers. The adviser may use the Fund&amp;#8217;s own net asset value or the return of closed-end funds as the underlying asset in a total return swap. The adviser utilizes a total return swap using the Fund&amp;#8217;s return as the underlying asset in order for the Fund&amp;#8217;s cash positions allocated to the swap to share in similar investment returns as the Fund itself while maintaining a sufficient cash position to meet liquidity needs in the Fund, including liquidity to invest in new investment opportunities. &lt;br /&gt;&lt;br /&gt; Core Fixed Income Strategy&lt;br /&gt;In implementing the Fund&amp;#8217;s Core Fixed Income strategy, the sub-adviser allocates that portion of the Fund&amp;#8217;s investments to a variety of fixed income instruments. These include securities issued or guaranteed by the United States Government, its agencies, instrumentalities or sponsored corporations; corporate obligations; agency mortgage-backed securities; non-agency mortgage-backed securities; commercial mortgage-backed securities; asset-backed securities; global developed credit (such as corporate obligations and foreign hybrid securities); foreign fixed income securities issued by corporations and governments; emerging market fixed income securities issued by corporations and governments; bank loans and assignments bearing fixed or variable interest rates of any maturity. There is no limit to the percentage of the strategy&amp;#8217;s assets that may be allocated to any of the above-listed securities. The term &amp;#8220;core&amp;#8221; is used to indicate that the portion of the Fund&amp;#8217;s assets allocated to this strategy will be the Fund&amp;#8217;s principal fixed income holdings under normal circumstances. &lt;br /&gt;&lt;br /&gt; The Fund may invest in junk bonds, bank loans and assignments and credit default swaps of companies in the high yield universe. The sub-adviser allocates the high yield portfolio holdings broadly by industry and issuer in an attempt to reduce the impact of negative events for an industry or issuer. The sub-adviser defines junk bonds as fixed income instruments that are at the time of investment unrated or rated BB+ or lower by S&amp;amp;P or Ba1 or lower by Moody&amp;#8217;s or the equivalent by any other nationally recognized statistical rating organization (&amp;#8220;NRSRO&amp;#8221;), or if unrated, of comparable quality in the opinion of the sub-adviser. High yield portfolio holdings are allocated broadly by industry and issuer in an attempt to reduce the impact of negative events for an industry or issuer. &lt;br /&gt;&lt;br /&gt; The sub-adviser may invest a portion of the assets allocated to the Core Fixed Income strategy in inverse floaters and interest-only and principal-only securities and a portion in fixed income instruments (including hybrid securities) issued or guaranteed by companies, financial institutions and government entities in emerging markets countries. &lt;br /&gt;&lt;br /&gt; The sub-adviser uses a controlled risk approach which includes consideration of: &lt;ul&gt;&lt;li type ="square"&gt; security selection within a given sector;&lt;/li&gt;&lt;li type ="square"&gt;  relative performance of the various market sectors;&lt;/li&gt;&lt;li type ="square"&gt; the shape of the yield curve; and&lt;/li&gt;&lt;li type ="square"&gt;  fluctuations in the overall level of interest rates.&lt;/li&gt;&lt;/ul&gt;The sub-adviser also utilizes active asset allocation in managing the strategy&amp;#8217;s investments and monitors the duration of the securities allocated to the strategy to seek to mitigate the strategy&amp;#8217;s exposure to interest rate risk. The sub-adviser intends to seek to construct, under normal circumstances, an investment portfolio with a weighted average effective duration of no less than two years and no more than eight years. &lt;br /&gt;&lt;br /&gt; Opportunistic Income Strategy &lt;br /&gt; In implementing the Fund&amp;#8217;s Opportunistic Income strategy, the sub-adviser allocates this portion of the Fund&amp;#8217;s investments to fixed income instruments and other investments including asset-backed securities; corporate bonds, including high-yield junk bonds; municipal bonds; and Real Estate Investment Trust (&amp;#8220;REITs&amp;#8221;). &lt;br /&gt;&lt;br /&gt; The strategy&amp;#8217;s investments may include substantial investments in mortgage-backed securities, including non-agency residential mortgage-backed securities (&amp;#8220;RMBS&amp;#8221;). These RMBS investments have undergone extreme volatility over the past several years, driven primarily by high default rates and the securities being downgraded to &amp;#8220;junk&amp;#8221; status. However, the sub-adviser utilizes a unique investment process that first examines the macroeconomic status of the mortgage-backed sector. This analysis includes reviewing information regarding interest rates, yield curves and spreads, credit analysis of the issuers and a general analysis of the markets generally. From this detailed analysis, along with assessment of other economic data including market trends, unemployment data and pending legislation, the sub-adviser identifies subsectors within the mortgage sector which offer the highest potential for return. The sub-adviser then applies a qualitative analysis of potential investments looking at factors such as duration, level of delinquencies and default history. Finally, the sub-adviser performs a quantitative analysis of the potential investment, essentially performing a stress test of the potential investment&amp;#8217;s underlying portfolio of mortgages. Only when a potential investment has passed the sub-adviser&amp;#8217;s careful screening will it be added to the strategy&amp;#8217;s portfolio. &lt;br /&gt;&lt;br /&gt; The sub-adviser may also utilize derivative instruments, including futures contracts, options and swaps as a substitute for taking positions in fixed income instruments, to hedge certain positions held in the strategy or to reduce exposure to other risks. &lt;br /&gt;&lt;br /&gt; The sub-adviser places no limits on the duration of the strategy&amp;#8217;s investment portfolio. The term &amp;#8220;opportunistic&amp;#8221; is used to indicate that the portion of the Fund&amp;#8217;s allocated to this strategy will be invested when certain market conditions exist that offer potentially attractive risk adjusted returns.</rr:StrategyNarrativeTextBlock>
  <rr:RiskHeading contextRef="Duration_02Feb2012_01Feb2013S000030798_Member">&lt;b&gt;Principal Risks &lt;/b&gt;</rr:RiskHeading>
  <rr:RiskNarrativeTextBlock contextRef="Duration_02Feb2012_01Feb2013S000030798_Member">&lt;b&gt;All mutual funds carry a certain amount of risk. The Fund&amp;#8217;s returns will vary and you could lose money on your investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the FDIC or any other government agency. Below is a summary of the principal risks of investing in the Fund. &lt;/b&gt;&lt;br /&gt;&lt;br /&gt; Asset-Backed Securities Investment Risk. The Fund may run the risk that the impairment of the value of the assets (whether tangible or intangible) underlying a security in which the Fund invests such as non-payment of loans, will result in a reduction in the value of the security. &lt;br /&gt;&lt;br /&gt; Borrowing Risk. The Fund may borrow amounts up to one-third of the value of total assets, but it will not borrow more than 5% of the value of its total assets except to satisfy redemption requests or for other temporary purposes. Such borrowings would result in increased expense to the Fund and, while they are outstanding, would magnify increases or decreases in the value of Fund shares. The Fund will not purchase additional portfolio securities while outstanding borrowings exceed 5% of the value of its total assets. &lt;br /&gt;&lt;br /&gt; Convertible Security Risk. The market value of convertible securities and other debt securities tends to fall when prevailing interest rates rise. The value of convertible securities also tends to change whenever the market value of the underlying common or preferred stock fluctuates. &lt;br /&gt;&lt;br /&gt; Defaulted Securities Risk. Defaulted securities carry with them the risk of the uncertainty of repayment and obligations of the distressed issuers. &lt;br /&gt;&lt;br /&gt; Derivatives Risk. To the extent the Fund invests in derivative securities, there is the risk that an insolvency of the counterparty to a derivative instrument could cause the Fund to lose all or substantially all of its investment in the derivative instrument, as well as the benefits derived therefrom. &lt;br /&gt;&lt;br /&gt; Emerging Markets Risk. Countries with emerging markets may have relatively unstable governments, social and legal systems that do not protect shareholders, economies based on only a few industries, and inefficient securities markets. &lt;br /&gt;&lt;br /&gt; Exchange-Traded Note Risk. The Fund may invest in ETNs, which are notes representing unsecured debt of the issuer. ETNs are typically linked to the performance of an index plus a specified rate of interest that could be earned on cash collateral. The value of an ETN may be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying markets, changes in the applicable interest rates, changes in the issuer&amp;#8217;s credit rating and economic, legal, political or geographic events that affect the referenced index. There may be restrictions on the Fund&amp;#8217;s right to redeem its investment in an ETN, and there may be limited availability of a secondary market. &lt;br /&gt;&lt;br /&gt; Fixed Income Risk. The Fund may invest directly or indirectly through Underlying Funds that invest in fixed income securities, including high yield junk bonds. Fixed income securities increase or decrease in value based on changes in interest rates. If interest rates increase, the value of the Fund&amp;#8217;s fixed income securities generally declines. On the other hand, if interest rates fall, the value of the fixed income securities generally increases. Junk bonds provide greater income and opportunity for gain, but entail greater risk of loss of principal. The issuer of a fixed income security may not be able to make interest and principal payments when due. With regard to junk bond issuers, the issuer&amp;#8217;s capacity to pay interest and repay principal in accordance with the terms of the obligation may be more at risk. &lt;br /&gt;&lt;br /&gt; Foreign Investing Risk. Investments in foreign securities may be affected by currency controls and exchange rates, different accounting, auditing, financial reporting, and legal standards and practices; expropriation; changes in tax policy; greater market volatility; differing securities market structures; higher transaction costs; and various administrative difficulties, such as delays in clearing and settling portfolio transactions or in receiving payment of dividends. These risks may be heightened in connection with investments in emerging or developing countries. &lt;br/&gt;&lt;br/&gt;Liquidity Risk. If the Fund invests in illiquid assets, or if asset become illiquid there may be no willing buyer of the securities and the Fund may have to sell those securities at a lower price or may not be able to sell the securities at all each of which would have a negative effect on performance. &lt;br /&gt;&lt;br /&gt; Management Risk. The adviser&amp;#8217;s and sub-adviser&amp;#8217;s judgments about the attractiveness, value and potential appreciation of a particular asset class or individual security in which the Fund invests may prove to be incorrect and there is no guarantee that the adviser&amp;#8217;s or sub-adviser&amp;#8217;s judgments will produce the desired results. &lt;br /&gt;&lt;br /&gt; Market Risk. Overall stock market risks may also affect the value of the Fund. Factors such as domestic economic growth and market conditions, interest rate levels, and political events affect the securities markets. &lt;br /&gt;&lt;br /&gt; Mortgage-Backed Securities Risk. Mortgage-backed securities have several risks, including: &lt;ul&gt;&lt;li type ="square"&gt; Credit and Market Risks of Mortgage-Backed Securities: the mortgage loans or the guarantees underlying the mortgage-backed securities may default or otherwise fail leading to non-payment of interest and principal.&lt;/li&gt;&lt;li type ="square"&gt; Prepayment Risk of Mortgage-Backed Securities: in times of declining interest rates, the Fund&amp;#8217;s higher yielding securities may be prepaid and the Fund will have to replace them with securities having a lower yield.&lt;/li&gt;&lt;li type ="square"&gt; Extension Risk of Mortgage-Backed Securities: in times of rising interest rates mortgage prepayments will slow causing portfolio securities considered short or intermediate term to be long-term securities which fluctuate more widely in response to changes in interest rates than shorter term securities.&lt;/li&gt;&lt;li type ="square"&gt; Inverse Floater, Interest- and Principal-Only Securities Risk: these securities are extremely sensitive to changes in interest rates and prepayment rates.&lt;/li&gt;&lt;li type ="square"&gt; Illiquidity of Mortgage Markets: the mortgage markets are currently facing additional economic pressures such as the devaluation of the underlying collateral, increased loan underwriting standards which limits the number of real estate purchasers, and excess supply of properties in certain geographic regions, which puts additional downward pressure on the value of real estate in these regions.&lt;/li&gt;&lt;/ul&gt; Portfolio Turnover Risk. The Fund may engage in short-term trading to try to achieve its objective and may have portfolio turnover rates in excess of 100%. Increased portfolio turnover may cause the Fund to incur higher brokerage costs, which may adversely affect the Fund&amp;#8217;s performance, and may produce increased taxable distributions. &lt;br /&gt;&lt;br /&gt; Rating Agency Risk. Ratings agencies such as S&amp;amp;P, Moody&amp;#8217;s or other NRSRO provide ratings on debt securities based on their analyses of information they deem relevant. Ratings are essentially opinions or judgments of the credit quality of an issuer and may prove to be inaccurate. In addition, there may be a delay between events or circumstances adversely affecting the ability of an issuer to pay interest and or repay principal and a NRSRO&amp;#8217;s decision to downgrade a security. &lt;br /&gt;&lt;br /&gt; REIT Risk. The value of equity REITs may be affected by changes in the value of the underlying property owned by the REITs, while the value of mortgage REITs may be affected by the quality of any credit extended. Investment in REITs involves risks similar to those associated with investing in small capitalization companies, and REITs (especially mortgage REITs) are subject to interest rate risks. Because REITs incur expenses like management fees, investments in REITs also add an additional layer of expenses. &lt;br /&gt;&lt;br /&gt; Security Risk. The value of the Fund may decrease in response to the activities and financial prospects of individual securities in the Fund&amp;#8217;s portfolio. &lt;br /&gt;&lt;br /&gt; Structured Notes Risk. Structured notes are subject to a number of fixed income risks including general market risk, interest rate risk, and the risk that the issuer on the note may fail to make interest and/or principal payments when due, or may default on its obligations entirely. In addition, as a result of the imbedded derivative features, structured notes generally are subject to more risk than investing in a simple note or bond issued by the same issuer. &lt;br /&gt;&lt;br /&gt; Swap Risk. The Fund may invest in interest rate, index, total return, currency and credit default swap agreements. The degree to which the Fund may invest in these instruments is not limited. All of these agreements are considered derivatives. Swaps could result in losses if interest or foreign currency exchange rates or credit quality changes are not correctly anticipated by the adviser. Total return swaps could result in losses if the reference index, security, or investments do not perform as anticipated. Credit default swaps can increase Fund exposure to credit risk and could result in losses if the adviser does not correctly evaluate the creditworthiness of the company or government on which the credit default swap is based. The use of swaps may not always be successful; using them could lower Fund total return, their prices can be highly volatile, and the potential loss from the use of swaps can exceed a Fund&amp;#8217;s initial investment in such instruments. Also, the other party to a swap agreement could default on its obligations or refuse to cash out a Fund&amp;#8217;s investment at a reasonable price, which could turn an expected gain into a loss. &lt;br /&gt;&lt;br /&gt; Underlying Fund Risk. The Fund will incur higher and duplicative expenses when it invests in Underlying Funds. There is also the risk that the Fund may suffer losses due to the investment practices of the Underlying Funds (such as the use of derivatives). The ETFs in which the Fund invests may not be able to replicate exactly the performance of the indices they track, due to transactions costs and other expenses of the ETFs. The shares of closed-end funds frequently trade at a discount to their net asset value. There can be no assurance that the market discount on shares of any closed-end fund purchased by the Fund will ever decrease, and it is possible that the discount may increase.</rr:RiskNarrativeTextBlock>
