Such events can include: mergers, bankruptcies, financial or operational stress, restructurings, asset sales, recapitalizations, spin-offs, litigation, regulatory and legislative changes as well as other types of corporate events. Small cap equities, high yield bonds, and the equities of distressed companies combined with credit derivatives are a proxy for the primary instruments and exposures traded by distressed and opportunistic credit funds. A merger arbitrage index offers exposure to a liquid, diversified and broadly representative set of arbitrage positions on announced American and Western European merger and acquisition deals. The illiquidity factor seeks to represent the risk premium that may be achieved by holding illiquid securities. The factors and weights of those factors identified by the algorithm may change over time and may be long or short at any given time. The Fund primarily seeks to obtain these exposures through swap agreements, but it also may invest in a combination of: domestic and foreign common stock; American Depositary Receipts (ADRs); credit or equity-linked instruments, primarily consisting of structured notes and exchange-traded notes (ETNs); exchange-traded funds (ETFs); other pooled investment vehicles; and other derivatives, primarily consisting of futures, options, and options on futures. While the Fund anticipates investing in these instruments to seek to achieve its investment objective, the extent of the Funds investment in these instruments may vary from day to day depending on a number of different factors, including price, availability, and general market conditions. The Funds use of derivatives and the leveraged investment exposure created by such use may be significant at times. Certain of the Funds derivative investments may be traded in the over-the-counter (OTC) market. From time to time, the Fund also may enter into short sales and invest in short positions of certain of its portfolio investments. The Fund may invest in derivatives to hedge or gain leveraged exposure to the components of a particular investable factor. On a day-to-day basis, the Fund may hold U.S. government securities, short-term, high quality (rated AA or higher) fixed income securities, money market instruments, overnight and fixed-term repurchase agreements, cash, and other cash equivalents with maturities of one year or less to collateralize its derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund also may engage in frequent and active trading or portfolio investments to achieve its investment objective. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund. Summarize how the Fund intends to achieve its investment objectives by identifying the Fund's principal investment strategies (including the type or types of securities in which the Fund invests or will invest principally) and any policy to concentrate in securities of issuers in a particular industry or group of industries.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection a false0Strategy Narrative [Text Block]20false 4rr_RiskHeadingrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00PRINCIPAL RISKSfalsefalsefalsexbrli:stringItemTypestringNarrative Risk Disclosure.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 1 false0Risk [Heading]21false 4rr_RiskNarrativeTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00As with all mutual funds, a shareholder is subject to the risk that his or her investment could lose money. In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: CFTC Regulatory RiskThe Commodity Futures Trading Commission (CFTC) has recently adopted amendments to certain CFTC rules, and is in the process of promulgating new rules, that will subject the Fund and the Advisor to certain CFTC disclosure, reporting, and recordkeeping requirements if the Fund does not operate within certain derivatives trading and marketing limitations. Compliance with these additional requirements will likely increase Fund expenses and may adversely affect the Funds ability to obtain exposure to certain investments and the commodities market generally. Certain of the regulatory requirements that would apply to the Fund have not yet been adopted, and it is unclear what the effect of those requirements would be on the Fund if they are adopted. Consistent with the Funds investment strategies and investment policies, the Advisor intends to maintain the flexibility to utilize certain derivatives beyond the CFTCs new trading limitations and to comply with CFTC rules to the extent required to maintain such investment flexibility. Counterparty Credit RiskThe Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Funds use of such financial instruments, including swap agreements and structured notes, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements and structured notes also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Funds investment. Credit and Equity-Linked Derivative Investment RiskThe value of the Funds investment in these securities will rise or fall in response to changes in the underlying security or related benchmark or investment. These securities expose the Fund economically to movements in the prices of the underlying credit or equity security. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. When used to generate leveraged exposure, the Funds investments in derivatives may expose the Fund to potentially dramatic losses (or gains) in the value of the derivative instruments. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Exchange-Traded Notes (ETNs) RiskThe 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 commodities or securities markets, changes in the applicable interest rates, changes in the issuers credit rating and economic, legal, political or geographic events that affect the referenced commodity or security. The Funds decision to sell its ETN holdings also may be limited by the availability of a secondary market. If the Fund must sell some or all of its ETN holdings and the secondary market is weak, it may have to sell such holdings at a discount. ETNs also are subject to counterparty credit risk and fixed income risk. Fixed Income RiskThe Funds investments in fixed income securities will change in value in response to interest rate changes and other factors, such as the perception of the issuers creditworthiness. For example, the value of fixed income securities will generally decrease when interest rates rise, which may cause the value of the Fund to decrease. In addition, the Funds investments in fixed income securities with longer maturities will fluctuate more in response to interest rate changes. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. High Yield RiskThe Fund may invest in high yield securities and unrated securities of similar credit quality (commonly known as junk bonds), which may be subject to greater levels of interest rate, credit and liquidity risk than funds that do not invest in such securities. The price of high yield securities tends to be more susceptible to issuer-specific operating results and outlook and to real or perceived adverse economic and competitive industry conditions. Investment in Investment Companies RiskInvesting in other investment companies, including ETFs, subjects the Fund to those risks affecting the investment company, including the possibility that the value of the underlying securities held by the investment company could decrease. Moreover, the Fund will incur its pro rata share of the expenses of the underlying investment companies expenses. Investment Technique RiskSome investment techniques of the Fund may be considered aggressive. Risks associated with the use of futures contracts, options, structured notes, and swap agreements include potentially dramatic price changes (losses) in the value of the instruments and imperfect correlations between the price of the contract and the underlying security or index. These instruments may increase the volatility of the Fund and may involve a small investment of cash relative to the magnitude of the risk assumed. Large-Capitalization Securities RiskThe Fund is subject to the risk that large-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Leveraging RiskThe Funds investment in derivative instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. The cost of investing in such instruments generally increases as interest rates increase, which will lower the Funds return. Liquidity RiskIn certain circumstances, it may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price. While the Fund intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a limit move, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. OTC Trading RiskCertain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts. Portfolio Turnover RiskThe Funds strategy may frequently involve buying and selling portfolio securities, which may lead to increased costs to the Fund. Portfolio turnover risk may cause the Funds performance to be less than you expect. Repurchase Agreement RiskThe Funds investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term. Short Sales RiskShort selling a security involves selling a borrowed security with the expectation that the value of the security will decline, so that the security may be purchased at a lower price when returning the borrowed security. The risk for loss on short selling is greater than the original value of the security sold short because the price of the borrowed security may rise, thereby increasing the price at which the security must be purchased. Government actions also may affect the Funds ability to engage in short selling. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell certain securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also should show the returns of an appropriate broad-based securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph
