The Fund&lt;br /&gt;seeks to generate returns through risk-controlled exposure to long and short&lt;br /&gt;positions in the global (U.S. and non-U.S.) equity, bond and currency markets&lt;br /&gt;through a wide range of derivative instruments and direct investments. Under&lt;br /&gt;normal circumstances, the Fund will invest at least 40% of its net assets, plus&lt;br /&gt;the amount of any borrowing for investment purposes, in investments (permitted&lt;br /&gt;by applicable law) of issuers organized, located, or doing a substantial amount&lt;br /&gt;of business outside of the United States, including investments exposed to such&lt;br /&gt;issuers, and the Fund will invest in or have investments exposed to a minimum of&lt;br /&gt;three countries, including the United States. The Fund's investment process&lt;br /&gt;involves an analysis of returns based on the (i) relative returns derived from&lt;br /&gt;global asset class performance (for example, how global stocks performed&lt;br /&gt;relative to global bonds and cash); (ii) relative returns within the equity&lt;br /&gt;asset class based on country (for example, how U.S. equities performed relative&lt;br /&gt;to other global equities); (iii) relative returns within the fixed-income asset&lt;br /&gt;class based on country (for example, how U.S. bonds performed relative to other &lt;br /&gt;global bonds); and (iv) risks associated with currencies (collectively, the "First&lt;br /&gt;Quadrant Analysis").&lt;br /&gt; &lt;br /&gt;The Fund may achieve long and short exposure to global equity, bond, and&lt;br /&gt;currency markets through a wide range of derivative instruments and direct&lt;br /&gt;investments. The Fund typically will make extensive use of derivative&lt;br /&gt;instruments, including futures contracts on global equity and fixed-income&lt;br /&gt;securities and security indices (including broad-based security indices),&lt;br /&gt;options on futures contracts, securities and security indices, swap contracts&lt;br /&gt;and forward contracts. The Fund may also invest directly in global equity&lt;br /&gt;securities (including exchange-traded funds ("ETFs") and common and preferred&lt;br /&gt;stock of U.S. and non-U.S. companies) and fixed-income securities.&lt;br /&gt; &lt;br /&gt;There are no limits on the amount of Fund assets that may be allocated to any&lt;br /&gt;one of the equity, bond, and currency asset classes; however, under normal&lt;br /&gt;circumstances, it is expected that no more than 50% of the Fund's exposure to&lt;br /&gt;such classes will be in currency forward contracts. Typically, the Fund expects&lt;br /&gt;to diversify its exposure among at least ten different countries, including the&lt;br /&gt;United States. In selecting equity investments for the Fund, First Quadrant is&lt;br /&gt;not constrained by any particular investment style or capitalization range. In&lt;br /&gt;selecting bond investments for the Fund, First Quadrant will have the flexibility &lt;br /&gt;to invest in debt-related investments of any credit quality and with any duration. &lt;br /&gt;The Fund is a "non-diversified fund," which means that it may invest more of its &lt;br /&gt;assets in the securities of a single issuer or a smaller number of issuers than &lt;br /&gt;a diversified fund. The Fund's investments in certain derivative instruments may &lt;br /&gt;be limited by tax considerations.&lt;br /&gt; &lt;br /&gt;The Fund may enter into short sales of securities (including ETFs). A short sale&lt;br /&gt;involves the sale of a security that is borrowed from a broker or other institution &lt;br /&gt;to complete the sale. Short sales expose the Fund to the risk that it will be &lt;br /&gt;required to acquire, convert or exchange securities to replace the borrowed &lt;br /&gt;securities at a time when the securities sold short have appreciated in value, &lt;br /&gt;thus resulting in a loss to the Fund. The Fund's loss on a short sale is&lt;br /&gt;potentially unlimited because there is no upward limit on the price a borrowed&lt;br /&gt;security could attain.&lt;/tt&gt;</rr:StrategyNarrativeTextBlock>

An investment in the Fund is not a deposit or&lt;br /&gt;obligation of any bank, is not endorsed or guaranteed by any bank, and is not&lt;br /&gt;insured by the Federal Deposit Insurance Corporation ("FDIC") or any other&lt;br /&gt;government agency. Below are some of the risks of investing in the Fund. The&lt;br /&gt;Fund may gain exposure to the instruments mentioned below directly, by investing&lt;br /&gt;in securities, or indirectly through the use of derivatives and ETFs.&lt;br /&gt; &lt;br /&gt;Asset Allocation Risk -the Fund's investments may not be allocated in the best&lt;br /&gt;performing asset classes.&lt;br /&gt; &lt;br /&gt;Credit and Counterparty Risk -the issuer of bonds or other debt securities or a&lt;br /&gt;counterparty to a derivatives contract may not be able to meet interest,&lt;br /&gt;principal or settlement payments or otherwise honor its obligations.&lt;br /&gt; &lt;br /&gt;Currency Risk -fluctuations in exchange rates may affect the total loss or gain&lt;br /&gt;on a non-U.S. dollar investment when converted back to U.S. dollars.&lt;br /&gt; &lt;br /&gt;Derivatives Risk -the complexity and rapidly changing structure of derivatives&lt;br /&gt;markets may increase the possibility of market losses.&lt;br /&gt; &lt;br /&gt;Exchange-Traded Fund Risk -because exchange-traded funds incur their own costs,&lt;br /&gt;investing in them could result in a higher cost to the investor.&lt;br /&gt; &lt;br /&gt;Foreign Investment Risk -securities or other investments of foreign issuers&lt;br /&gt;involve additional risks (such as risks arising from less frequent trading,&lt;br /&gt;changes in political or social conditions, and less publicly available&lt;br /&gt;information about non-U.S. issuers) that differ from those associated with&lt;br /&gt;investing in securities of U.S. issuers and may result in greater price&lt;br /&gt;volatility.&lt;br /&gt; &lt;br /&gt;Hedging Risk -there is no guarantee that hedging strategies, if any, will be&lt;br /&gt;successful.&lt;br /&gt; &lt;br /&gt;Inflation Risk -the price of an asset, or the income generated by an asset, may&lt;br /&gt;not keep up with the cost of living.&lt;br /&gt; &lt;br /&gt;Interest Rate Risk -fixed-coupon payments (cash flows) of bonds and debt&lt;br /&gt;securities may become less competitive with the market in periods of rising&lt;br /&gt;interest rates and cause bond prices to decline.&lt;br /&gt; &lt;br /&gt;Leverage Risk -borrowing, and some derivative investments such as futures and&lt;br /&gt;forward commitment transactions, may magnify smaller adverse market movements&lt;br /&gt;into relatively larger losses.&lt;br /&gt; &lt;br /&gt;Liquidity Risk -particular investments, such as illiquid securities, may not be&lt;br /&gt;able to be sold at the price the Fund would like or the Fund may have to sell&lt;br /&gt;them at a loss.&lt;br /&gt; &lt;br /&gt;Market Risk -market prices of investments held by the Fund may fall rapidly or&lt;br /&gt;unpredictably due to a variety of factors, including changing economic,&lt;br /&gt;political, or market conditions.&lt;br /&gt; &lt;br /&gt;Non-Diversified Fund Risk -the Fund is non-diversified and therefore a greater&lt;br /&gt;percentage of holdings may be concentrated in a small number of issuers or a&lt;br /&gt;single issuer, such as a corporate or government entity, which can place the&lt;br /&gt;Fund at greater risk.&lt;br /&gt; &lt;br /&gt;Political Risk -changes in the political status of any country can have profound&lt;br /&gt;effects on the value of investments exposed to that country.&lt;br /&gt; &lt;br /&gt;Prepayment Risk -many bonds and debt securities have call provisions that may&lt;br /&gt;result in debtors paying back the debt prior to maturity during periods of&lt;br /&gt;decreasing interest rates.&lt;br /&gt; &lt;br /&gt;Reinvestment Risk -investors may have difficulty reinvesting payments from&lt;br /&gt;debtors and may receive lower rates than from their original investments.&lt;br /&gt; &lt;br /&gt;Short Sales Risk -the sale of a security that is borrowed may subject the Fund &lt;br /&gt;to potentially unlimited losses.&lt;br /&gt; &lt;br /&gt;Tax Risk -although the Fund is expected to qualify as a regulated investment&lt;br /&gt;company, it may not qualify, which could result in higher taxes to shareholders&lt;br /&gt;and imposition of tax at the Fund level.&lt;br /&gt; &lt;br /&gt;U.S. Government Securities Risk -obligations issued by some U.S. Government&lt;br /&gt;agencies, authorities, instrumentalities, or sponsored enterprises such as&lt;br /&gt;Government National Mortgage Association ("GNMA"), are backed by the full faith&lt;br /&gt;and credit of the U.S. Government, while obligations issued by others, such as&lt;br /&gt;Federal National Mortgage Association ("FNMA"), Federal Home Loan Mortgage&lt;br /&gt;Corporation ("FHLMC"), and Federal Home Loan Banks ("FHLBs") are not backed by&lt;br /&gt;the full faith and credit of the U.S. Government and are backed solely by the&lt;br /&gt;entity's own resources or by the ability of the entity to borrow from the U.S.&lt;br /&gt;Treasury. If one of these agencies defaulted on a loan, there is no guarantee&lt;br /&gt;that the U.S. Government will provide financial support.&lt;/tt&gt;</rr:RiskNarrativeTextBlock>

All investments&lt;br /&gt;carry a certain amount of risk and the Fund cannot guarantee that it will&lt;br /&gt;achieve its investment objective. An investment in the Fund is not a deposit or&lt;br /&gt;obligation of any bank, is not endorsed or guaranteed by any bank, and is not&lt;br /&gt;insured by the Federal Deposit Insurance Corporation ("FDIC") or any other&lt;br /&gt;government agency. Below are some of the risks of investing in the Fund.&lt;br /&gt; &lt;br /&gt;Derivatives Risk -the complexity and rapidly changing structure of derivatives&lt;br /&gt;markets may increase the possibility of market losses.&lt;br /&gt; &lt;br /&gt;Growth Stock Risk -growth stocks may be more sensitive to market movements&lt;br /&gt;because their prices tend to reflect future investor expectations rather than&lt;br /&gt;just current profits.&lt;br /&gt; &lt;br /&gt;Hedging Risk -there is no guarantee that hedging strategies, if any, will be&lt;br /&gt;successful.&lt;br /&gt; &lt;br /&gt;Large-Capitalization Stock Risk -the stocks of large-capitalization companies are&lt;br /&gt;generally more mature and may not be able to reach the same levels of growth as&lt;br /&gt;the stocks of small- or mid-capitalization companies.&lt;br /&gt; &lt;br /&gt;Market Risk -market prices of securities held by the Fund may fall rapidly or&lt;br /&gt;unpredictably due to a variety of factors, including changing economic,&lt;br /&gt;political, or market conditions.&lt;br /&gt; &lt;br /&gt;Small- and Mid-Capitalization Stock Risk -the stocks of small- and&lt;br /&gt;mid-capitalization companies often have greater price volatility, lower trading&lt;br /&gt;volume, and less liquidity than the stocks of larger, more established&lt;br /&gt;companies.&lt;/tt&gt;</rr:RiskNarrativeTextBlock>

Investment weights&lt;br /&gt;within asset classes are set with the objective of balancing risk. Applying this&lt;br /&gt;investment process, the Fund seeks to provide greater capital loss protection&lt;br /&gt;during down markets than traditional balanced portfolios, as well as participate&lt;br /&gt;in market gains.&lt;br /&gt; &lt;br /&gt;In selecting equity investments for the Fund, First Quadrant is not constrained&lt;br /&gt;by any particular investment style or capitalization range. In selecting debt&lt;br /&gt;investments for the Fund, First Quadrant will have the flexibility to invest in&lt;br /&gt;debt-related investments of any credit quality and with any duration.&lt;br /&gt; &lt;br /&gt;First Quadrant L.P. ("First Quadrant") serves as Subadvisor to the Fund and&lt;br /&gt;applies a proprietary, quantitatively based investment process designed to&lt;br /&gt;provide a diversified, risk-balanced global market portfolio. First Quadrant&lt;br /&gt;continually monitors the Fund's investments utilizing a risk based approach and&lt;br /&gt;seeks to dynamically rebalance the Fund to achieve an optimal total portfolio&lt;br /&gt;risk target. First Quadrant anticipates that the Fund generally will maintain&lt;br /&gt;exposures to developed markets, emerging markets, small capitalization&lt;br /&gt;securities, real estate investment trusts ("REITS"), sovereign debt, inflation&lt;br /&gt;protected securities, high yield bonds and commodities (through companies in the&lt;br /&gt;commodities sector, instruments linked to a commodity index or futures contract&lt;br /&gt;or otherwise). The Fund may achieve long and short exposure to global equity,&lt;br /&gt;bond, and currency markets through a wide range of derivative instruments and&lt;br /&gt;direct investments. The Fund typically will make extensive use of derivative&lt;br /&gt;instruments, including futures contracts on global equity and fixed-income&lt;br /&gt;securities and security indices (including broad-based security indices),&lt;br /&gt;options on futures contracts, securities and security indices, swap contracts&lt;br /&gt;and forward contracts, and also ETFs. The Fund may also invest directly in&lt;br /&gt;global equity securities (including investments in ETFs, common and preferred&lt;br /&gt;stock of U.S. and non-U.S. companies) and global fixed-income securities&lt;br /&gt;(including U.S. and non-U.S. corporate debt, zero coupon securities, inflation&lt;br /&gt;protected securities and debt securities guaranteed by U.S. and non-U.S.&lt;br /&gt;governments, their agencies or instrumentalities or supranational organizations&lt;br /&gt;such as the World Bank and the United Nations).&lt;br /&gt; &lt;br /&gt;In addition, the Fund may invest in commodity-linked derivative instruments &lt;br /&gt;and investment vehicles that exclusively invest in various commodities or have&lt;br /&gt;economic exposure to commodities, such as ETFs that invest in securities of&lt;br /&gt;companies in the commodity sector and/or ETNs, including leveraged ETNs, linked&lt;br /&gt;to one or more commodity indices through commodity futures contracts.&lt;/tt&gt;</rr:StrategyNarrativeTextBlock>

All investments&lt;br /&gt;carry a certain amount of risk and the Fund cannot guarantee that it will&lt;br /&gt;achieve its investment objective. An investment in the Fund is not a deposit or&lt;br /&gt;obligation of any bank, is not endorsed or guaranteed by any bank, and is not&lt;br /&gt;insured by the Federal Deposit Insurance Corporation ("FDIC") or any other&lt;br /&gt;government agency. Below are some of the risks of investing in the Fund. The&lt;br /&gt;Fund may gain exposure to the instruments mentioned below directly, by investing&lt;br /&gt;in securities, or indirectly through the use of derivatives, ETFs and ETNs.&lt;br /&gt; &lt;br /&gt;Asset Allocation Risk -the Fund's investments may not be allocated in the best&lt;br /&gt;performing asset classes.&lt;br /&gt; &lt;br /&gt;Commodities Exposure Risk -exposure to commodities through investments exposed to&lt;br /&gt;companies in the commodities sector or commodity futures or otherwise may result&lt;br /&gt;in losses for the Fund. Commodity prices, and the value of stocks of companies&lt;br /&gt;exposed to commodities, and commodity futures prices, and therefore ETNs exposed&lt;br /&gt;to such commodity futures, can be extremely volatile and are affected by a wide&lt;br /&gt;range of factors, including market movements, supply and demand imbalances and&lt;br /&gt;inflationary trends.&lt;br /&gt; &lt;br /&gt;Credit and Counterparty Risk -the issuer of bonds, ETNs or other debt securities&lt;br /&gt;or a counterparty to a derivatives contract may not be able to meet interest,&lt;br /&gt;principal or settlement payments or otherwise honor its obligations.&lt;br /&gt; &lt;br /&gt;Currency Risk -fluctuations in exchange rates may affect the total loss or gain&lt;br /&gt;on a non-U.S. dollar investment when converted back to U.S. dollars.&lt;br /&gt; &lt;br /&gt;Derivatives Risk -the complexity and rapidly changing structure of derivatives&lt;br /&gt;markets may increase the possibility of market losses.&lt;br /&gt; &lt;br /&gt;Emerging Markets Risk -investments in emerging markets can be subject to the&lt;br /&gt;general risks of foreign investments, as well as additional risks which can&lt;br /&gt;result in greater price volatility.&lt;br /&gt; &lt;br /&gt;Exchange-Traded Fund Risk -because exchange-traded funds incur their own costs,&lt;br /&gt;investing in them could result in a higher cost to the investor.&lt;br /&gt; &lt;br /&gt;Exchange-Traded Note Risk -the value of an ETN may be influenced by fluctuations&lt;br /&gt;in the values of the underlying assets or instruments, time to maturity, level&lt;br /&gt;of supply and demand for the ETN, volatility and lack of liquidity in the&lt;br /&gt;underlying markets, changes in applicable interest rates, and changes in the&lt;br /&gt;issuer's credit rating. The Fund bears any fees and expenses associated with&lt;br /&gt;investment in ETNs. There may be restrictions on the Fund's right to redeem its&lt;br /&gt;investment in an ETN meant to be held to maturity, and it may be difficult for&lt;br /&gt;the Fund to sell its ETN holdings.&lt;br /&gt; &lt;br /&gt;Foreign Investment Risk -securities or other investments of foreign issuers&lt;br /&gt;involve additional risks (such as risks arising from less frequent trading,&lt;br /&gt;changes in political or social conditions, and less publicly available&lt;br /&gt;information about non-U.S. issuers) that differ from those associated with&lt;br /&gt;investing in securities of U.S. issuers and may result in greater price&lt;br /&gt;volatility.&lt;br /&gt; &lt;br /&gt;Hedging Risk -there is no guarantee that hedging strategies, if any, will be&lt;br /&gt;successful.&amp;#xA0;&amp;#xA0;&lt;br /&gt;&lt;br /&gt;High Yield Risk -below-investment grade debt securities and unrated securities &lt;br /&gt;of similar credit quality (commonly known as "junk bonds" or "high yield&lt;br /&gt;securities") may be subject to greater levels of interest rate, credit, and&lt;br /&gt;liquidity risk.&lt;br /&gt; &lt;br /&gt;Inflation Risk -the price of an asset, or the income generated by an asset, may&lt;br /&gt;not keep up with the cost of living.&lt;br /&gt; &lt;br /&gt;Interest Rate Risk -fixed-coupon payments (cash flows) of bonds and debt&lt;br /&gt;securities may become less competitive with the market in periods of rising&lt;br /&gt;interest rates and cause prices to decline.&lt;br /&gt; &lt;br /&gt;Leverage Risk -borrowing, leveraged ETNs, futures, forward commitment&lt;br /&gt;transactions and other derivative investments may magnify smaller adverse market&lt;br /&gt;movements into relatively larger losses.&lt;br /&gt; &lt;br /&gt;Liquidity Risk -particular investments, such as illiquid securities, may not be&lt;br /&gt;able to be sold at the price the Fund would like or the Fund may have to sell&lt;br /&gt;them at a loss.&lt;br /&gt; &lt;br /&gt;Market Risk -market prices of investments held by the Fund may fall rapidly or&lt;br /&gt;unpredictably due to a variety of factors, including changing economic,&lt;br /&gt;political, or market conditions.&lt;br /&gt; &lt;br /&gt;Political Risk -changes in the political status of any country can have profound&lt;br /&gt;effects on the value of investments exposed to that country.&lt;br /&gt; &lt;br /&gt;Prepayment Risk -many bonds and debt securities have call provisions that may&lt;br /&gt;result in debtors paying back the debt prior to maturity during periods of&lt;br /&gt;decreasing interest rates.&lt;br /&gt; &lt;br /&gt;Real Estate Industry Risk -investments in the Fund may be subject to many of &lt;br /&gt;the same risks as a direct investment in real estate; in addition, equity REITs &lt;br /&gt;may be affected by changes in the value of their underlying properties.&lt;br /&gt; &lt;br /&gt;Reinvestment Risk -investors may have difficulty reinvesting payments from&lt;br /&gt;debtors and may receive lower rates than from their original investments.&lt;br /&gt; &lt;br /&gt;Sector Risk -issuers that are in similar industry sectors may be similarly&lt;br /&gt;affected by particular economic or market events; to the extent the Fund has&lt;br /&gt;substantial holdings within a particular sector, the risks associated with that&lt;br /&gt;sector increase.&lt;br /&gt; &lt;br /&gt;Small-Capitalization Stock Risk -the stocks of small-capitalization companies&lt;br /&gt;often have greater price volatility, lower trading volume, and less liquidity&lt;br /&gt;than the stocks of larger, more established companies.&lt;br /&gt; &lt;br /&gt;Tax Risk -although the Fund is expected to qualify as a regulated investment&lt;br /&gt;company, it may not qualify, which could result in higher taxes to shareholders&lt;br /&gt;and imposition of tax at the Fund level.&lt;br /&gt; &lt;br /&gt;U.S. Government Securities Risk -obligations issued by some U. S. Government&lt;br /&gt;agencies, authorities, instrumentalities, or sponsored enterprises such as&lt;br /&gt;Government National Mortgage Association ("GNMA"), are backed by the full faith&lt;br /&gt;and credit of the U.S. Government, while obligations issued by others, such as&lt;br /&gt;Federal National Mortgage Association ("FNMA"), Federal Home Loan Mortgage&lt;br /&gt;Corporation ("FHLMC"), and Federal Home Loan Banks ("FHLBs") are not backed by&lt;br /&gt;the full faith and credit of the U.S. Government and are backed solely by the&lt;br /&gt;entity's own resources or by the ability of the entity to borrow from the U.S.&lt;br /&gt;Treasury. If one of these agencies defaulted on a loan, there is no guarantee&lt;br /&gt;that the U.S. Government will provide financial support.&lt;/tt&gt;</rr:RiskNarrativeTextBlock>

The&lt;br /&gt;Benchmark measures the performance of the largest 3,000 U.S. companies based &lt;br /&gt;on total market capitalization, which represents approximately 98% of the&lt;br /&gt;investable U.S. equity market. As of June 27, 2011, the Benchmark had a market&lt;br /&gt;capitalization range of approximately $32 million to $383.8 billion.&amp;#xA0;&amp;#xA0;First &lt;br /&gt;Quadrant will manage the Fund's portfolio to minimize taxable distributions &lt;br /&gt;to shareholders and will apply a variety of tax-sensitive investment techniques. &lt;br /&gt;The Fund can be expected to distribute a smaller percentage of its returns each &lt;br /&gt;year than other equity mutual funds that are managed without regard to tax &lt;br /&gt;considerations. The Fund may use derivatives, such as futures and options, &lt;br /&gt;for any reason, including to enhance return, earn income or reduce exposure &lt;br /&gt;to other risks.&lt;/tt&gt;</rr:StrategyNarrativeTextBlock>
