Portfolio Turnover, Heading	rr_PortfolioTurnoverHeading	PORTFOLIO TURNOVER
Portfolio Turnover	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Example, affect the Fund's performance. The Fund's portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund's portfolio turnover rate might be significantly higher.
Acquired Fund Fees and Expenses, Based on Estimates	rr_AcquiredFundFeesAndExpensesBasedOnEstimates	"Other Expenses," "Other Expenses of the Fund," and "Other Expenses of the Subsidiary" are based on estimated amounts for the current fiscal year.
Expense Example, Heading	rr_ExpenseExampleHeading	EXAMPLE
Expense Example, Narrative	rr_ExpenseExampleNarrativeTextBlock	This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
Investment Strategy, Heading	rr_StrategyHeading	PRINCIPAL INVESTMENT STRATEGIES
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund's investment strategy focuses on the use of a systematic, price-based statistical process to identify and profit from price trends in a diverse selection of commodity and financial futures markets. The strategy's universe of markets includes all of the major liquid, exchanged-traded futures and foreign exchange markets principally in the commodity, currency, fixed income, and equity index sectors. The Advisor uses proprietary methods of comparing current prices to historical prices over varying periods of time to identify trends of varying lengths in the commodity and financial markets. When a price trend in a particular market for a specific time frame is identified, the strategy will take either a long or short position in the related futures or forward contract. If the strategy does not identify a trend, the Fund's portfolio will not establish a position with exposure to that particular market segment. The size of each position is determined by the estimated risk of each position as measured by recent volatility. Position sizes also may be constrained by position margin requirements, liquidity needs, leverage limits, and other portfolio or market measures. The Advisor may employ systematic relative value trading strategies and other risk-management strategies in an effort to mitigate declines in the market price of the Fund's shares, reduce risk, and improve returns over time. Such strategies may reduce the Fund's level of investment during periods of declining Fund performance. The Fund will implement the strategy's targeted exposures principally through the use of futures, forwards, and swap agreements. The Fund may invest in a variety of futures, forwards and swap agreements, including those based on interest rates, commodities, currencies, fixed income securities, equities and equity indices. Options on futures and options will be employed principally for hedging purposes, especially as tools of the risk management strategies. In the course of implementing the Fund's investment strategy, the Advisor may purchase and sell options and futures contracts. Certain of the Fund's derivative investments may be traded in the over-the-counter ("OTC") market. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in "managed futures." For these purposes, managed futures are investments in equity-linked, commodity-linked, currency-linked and financial-linked instruments, as well as U.S. government securities and money market instruments, that taken together have economic characteristics similar or equivalent to those of the listed commodity, currency and financial futures contracts described above. On a day-to-day basis, the Fund may hold U.S. government securities, short-term fixed-income securities (generally rated AA or higher), money market instruments, overnight and fixed-term repurchase agreements, cash, and other cash equivalents with maturities of one year or less to collateralize it derivatives positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. The Fund may invest up to 25% of its total assets in a wholly-owned and controlled Cayman Islands subsidiary (the "Subsidiary"). The Subsidiary is advised by the Advisor, and has the same investment objective as the Fund. Unlike the Fund, however, the Subsidiary may invest to a greater extent in commodity-linked derivative instruments. The Subsidiary's investments in such instruments are subject to limits on leverage imposed by the Investment Company Act of 1940 (the "Investment Company Act"). The Fund's investment in the Subsidiary is expected to provide the Fund with an effective means of obtaining exposure to the investment returns of global commodities markets. 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 is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund. The Fund has adopted an investment policy to not invest 25% or more of the value of its assets in the securities of one or more issuers conducting their principal business activities in the same industry.
Risk, Heading	rr_RiskHeading	PRINCIPAL RISKS
Risk, Narrative	rr_RiskNarrativeTextBlock	As 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: Active Trading Risk - Active trading, also called "high portfolio turnover," may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance and result in short-term capital gains, which have a negative tax effect. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Fund's ability to achieve its investment objective. Commodity-linked Derivative Investment Risk - The Fund may invest in commodity-linked derivative instruments. The value of a commodity-linked derivative investment typically is based upon the price movements of a physical commodity (such as heating oil, livestock, or agricultural products), a commodity futures contract or commodity index, or some other readily measurable economic variable dependent upon changes in the value of commodities or the commodities markets. The value of these securities will rise or fall in response to changes in the underlying commodity or related benchmark or investment. These securities expose the Fund economically to movements in commodity prices. The Fund's investment in commodity-related investment products may lead to losses in excess of the Fund's investment in such products. Such losses can significantly and adversely affect the net asset value of the Fund and, consequently, a shareholder's interest in the Fund. Counterparty Credit Risk - The Fund may make investments 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 Fund's use of such financial instruments, including swap agreements, 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 also may be considered to be illiquid. Currency Risk - The Fund's indirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of short positions, that the U.S. dollar will decline in value relative to the currency being hedged. The Fund also may incur transaction costs in connection with conversions between various currencies. Derivatives Risk - The Fund's 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 Fund's other portfolio holdings, lack of availability and counterparty risk. While the majority of the Fund's derivative investments will be used to obtain exposure to the commodities markets, certain of the Fund's derivative investments will be employed to hedge risk and limit leveraged exposure. There is no guarantee that such hedging strategies will be effective at managing risk. Early Closing Risk - The Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Fund's inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Fixed Income Risk - The Fund's investments in fixed income securities will change in value in response to interest rate changes and other factors, such as the perception of the issuer's 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 Fund's investments in fixed income securities with longer maturities will fluctuate more in response to interest rate changes. Foreign Issuer Exposure Risk - The Fund may invest in securities of foreign companies directly, or indirectly through the use of other investment companies and financial instruments that are 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. Investment In The Subsidiary Risk - The Subsidiary is not registered under the Investment Company Act and, unless otherwise noted in this Prospectus, is not subject to all of the investor protections of the Investment Company Act. Thus, the Fund, as the sole investor in the Subsidiary, will not have all of the protections offered to shareholders of registered investment companies. By investing in the Subsidiary, the Fund is exposed to the risks of the Subsidiary's investments, which in turn will be exposed primarily to the risks of investing in the commodities markets. The Fund also will incur its pro rata share of the expenses of the Subsidiary. In addition, changes in the laws of the United States or the Cayman Islands, under which the Fund and the Subsidiary, respectively, are organized, could result in the inability of the Fund and/or the Subsidiary to operate as intended and could negatively affect the Fund and its shareholders. Investment Technique Risk - Some investment techniques of the Fund, such as its use of derivatives and other commodity-linked financial instruments to seek to achieve its investment objective, may be considered aggressive. 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. Such investment techniques may not consistently produce desired results and may be limited by legislative, regulatory, or tax developments. Leveraging Risk - The Fund derives substantially all of its commodities exposure from its investment in derivatives and other financial instruments that provide leveraged exposure. The Fund's investment in these 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. Because such instruments are an integral part of the Fund's investment strategy, the use of such instruments may expose the Fund to potentially dramatic losses or gains in the value of its portfolio. The cost of investing in such instruments generally increases as interest rates increase, which will lower the Fund's return. Liquidity Risk - In 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 only 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 an investment. 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 these investments. Market Risk - The Fund's investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Fund's value, to fluctuate over time. An investment in the Fund may lose money. Non-Diversification Risk - The 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 Risk - Certain 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 Risk - The Fund's strategy may frequently involve buying and selling portfolio securities, which may lead to increased costs to the Fund. Portfolio turnover risk may cause the Fund's performance to be less than you expect. Repurchase Agreement Risk - The Fund's 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 Risk - Short 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 Fund's ability to engage in short selling. Tax Risk - The Fund currently gains most of its exposure to the commodities markets through its investment in the Subsidiary which may invest in commodity-linked derivative instruments and other similar instruments. However, to the extent the Fund invests in such instruments directly, it may be subject to the risk that such instruments will not generate qualifying income and, thus, may compromise the Fund's ability to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code of 1986, as amended. If the Fund invests in such instruments directly, it intends to restrict its income from commodity-linked derivative instruments that do not generate qualifying income, such as commodity-linked swaps, to a maximum of 10% of its gross income (when combined with its other investments that produce non-qualifying income), to ensure its continued ability to qualify as a regulated investment company. The tax treatment of certain commodity-linked derivative instruments may be affected by future regulatory or legislative changes that could affect the character, timing and/or amount of the Fund's taxable income or gains and distributions. Temporary Defensive Investment Risk - The Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets. Trading Halt Risk - If 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 Fund's ability to use leverage and may prevent the Fund from achieving its investment objective.

[1] "Other Expenses," "Other Expenses of the Fund," and "Other Expenses of the Subsidiary" are based on estimated amounts for the current fiscal year.

[2] The Advisor has contractually agreed to waive the management fee it receives from the Fund in an amount equal to the management fee paid to the Advisor by the Subsidiary. This fee waiver amounts to 0.23%. This undertaking will continue in effect for so long as the Fund invests in the Subsidiary, and may be terminated only with the approval of the Fund's Board of Trustees. In any event, this undertaking will continue for at least twelve months from the date of this Prospectus.

[3] The Advisor has contractually agreed to reduce fees and/or reimburse expenses to the extent necessary to keep net operating expenses for Institutional Class Shares (excluding interest, taxes, brokerage commissions, Acquired Fund Fees and Expenses, dividends on securities sold short, and extraordinary expenses ("Excluded Expenses")) from exceeding 1.25% of the Fund's Institutional Class Shares average daily net assets. The Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement includes Excluded Expenses and, thus, from time to time may be higher than 1.25%. This Agreement may be terminated only with the approval of the Fund's Board of Trustees. In any event, this undertaking will continue for at least twelve months from the date of this Prospectus.
