AQR Global Macro Fund

Fund Summary – AQR Global Macro Fund

Investment Objective

The AQR Global Macro Fund (the “Fund”) seeks positive absolute returns.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses AQR Global Macro Fund		Class I	Class N
Management Fee		1.25%	1.25%
Distribution (12b-1) fee		none	0.25%
Other Expenses	[1]	0.59%	0.62%
Total Annual Fund Operating Expenses		1.84%	2.12%
Less: Fee Waivers and/or Expense Reimbursements	[2]	0.39%	0.42%
Total Annual Fund Operating Expenses after Fee Waivers and/or Expense Reimbursements		1.45%	1.70%

Example:

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 and takes into account the effect of the Fee Waiver Agreement through April 30, 2016, as discussed in Footnote No. 2 to the Fee Table. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example AQR Global Macro Fund (USD $)	1 Year	3 Years
Class I Shares	148	497
Class N Shares	173	577

Portfolio Turnover:

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. The Fund has not commenced operations as of the date of this prospectus.

Principal Investment Strategies of the Fund

The Fund pursues its investment objective by investing globally across a wide range of asset classes, including equities, fixed income, currencies and commodities, and may take both “long” and “short” positions in each of the asset classes or Instruments (as defined below). The Fund has the flexibility to shift its allocation across asset classes and markets around the world, including emerging markets, based on the Adviser’s assessment of their relative attractiveness.

The Adviser uses a bottom up systematic process that considers four primary indicators of attractiveness in determining whether to take a long or short position in an Instrument or asset class: macroeconomic data, value, momentum, and carry.

Macroeconomic Data: The Adviser seeks to evaluate the impact of macroeconomic news and macroeconomic momentum on the attractiveness of Instruments and asset classes around the world. Macroeconomic themes considered include, but are not limited to, business cycles, international trade, monetary policy, investor sentiment and asset-specific fundamentals.

The evaluation of macroeconomic attractiveness includes both quantitative and qualitative components.

• Quantitative analysis measures an Instrument’s attractiveness based on the current level and historical evolution of key macroeconomic measures. These measures include, but are not limited to, growth and inflation forecasts, demand for exports, central bank actions and equity market performance.

• Qualitative input adds a perspective not available through quantitative analysis. These considerations include, but are not limited to, the Adviser’s assessment of fiscal and monetary policy, trade policy, geo-political risks and supply-and-demand conditions.

The Adviser combines the quantitative and qualitative components into an overall indicator of the macroeconomic attractiveness of an Instrument or asset class. When the quantitative and qualitative assessments agree, the long or short position in an Instrument or asset class will be given greater weighting within the portfolio, while conflicting assessments will result in a lesser weighting.

Value: Value strategies favor investments that appear cheap over those that appear expensive based on fundamental measures related to price, seeking to capture the tendency for relatively cheap assets to outperform relatively expensive assets. The Fund will seek to buy assets that are cheap and sell those that are expensive relative to similar investments globally and relative to their historical averages. Examples of value measures include using price-to-earnings and price-to-book ratios for selecting equities.

Momentum: Momentum strategies favor investments that have performed relatively well over those that have underperformed over the medium-term, seeking to capture the tendency that an asset’s recent performance will continue in the near future. The Fund will seek to buy assets that recently outperformed and sell those that recently underperformed relative to similar investments globally and relative to their historical averages. Examples of momentum measures include simple price momentum for selecting equities and price- and yield-based momentum for selecting bonds.

Carry: Carry strategies favor investments with higher yields over those with lower yields, seeking to capture the tendency for higher yielding assets to provide higher returns than lower-yielding assets. The Fund will seek to buy high-yielding assets and sell low-yielding assets relative to similar investments globally and relative to their historical averages. An example of carry measures includes using interest rates to select currencies and bonds.

Portfolio Construction

Each of the four primary indicators of attractiveness (macroeconomic data, value, momentum and carry) is taken into consideration in determining whether the portfolio’s position in the Instrument in question should be long or short. The owner of a “long” position in an Instrument will benefit from an increase in the price of the underlying security or instrument. The owner of a “short” position in an Instrument will benefit from a decrease in the price of the underlying security or instrument. The Fund goes long Instruments deemed overall attractive, and short Instruments deemed overall unattractive. When there is strong agreement among the four indicators, the long or short position in an Instrument or asset class will be given a greater weighting in the portfolio, while conflicting indicators will result in a lesser weighting. Individual investments are bought or sold in accordance with periodic re-ranking and rebalancing, the frequency of which is expected to vary depending on the Adviser’s assessment of the investment’s attractiveness and global market conditions.

The Adviser allocates among the different asset classes based on their contribution to the Fund’s risk budget—i.e., the targeted level of risk or volatility. The allocation process allows the Adviser to make tactical risk adjustments while maintaining long-term strategic risk weights. Within each asset class, approximately 50% of the Fund’s target risk is expected to be allocated based on the macroeconomic indicators, and the remaining 50% of target risk is expected to be allocated based on the value, momentum, and carry indicators. These relative weights, and the relative weights to each of the value, momentum and carry indicators, can vary depending on market conditions.

The Adviser generally expects that the Fund’s performance will have a low correlation to the performance of the general global equity, fixed income, currency and commodity markets over any given market cycle; however, the Fund’s performance may correlate to the performance of any one or more of those markets over short-term periods.

The Adviser will use quantitative and qualitative methods to assess the level of risk (i.e., volatility of return) for the Fund. Volatility is a statistical measurement of the dispersion of returns of a security or fund or index, as measured by the annualized standard deviation of its returns. Higher volatility generally indicates higher risk. The Fund’s returns are expected to be volatile because of the significant use of Instruments that have a leveraging effect; however, the Adviser, on average, will target an annualized volatility level for the Fund of 10%. The Adviser expects that the Fund’s targeted annualized forecasted volatility will typically range between 5% and 15%; however, the actual or realized volatility level for longer or shorter periods may be materially higher or lower depending on market conditions. Actual or realized volatility can and will differ from the forecasted or target volatility described above.

Instruments

Generally, the Fund will invest in Instruments providing exposure to a number of different countries throughout the world, one of which may be the United States. Under normal circumstances, the Fund will invest significantly (at least 40%, unless market conditions are not deemed favorable by the Adviser in which case the Fund would invest at least 30%) outside the U.S., primarily through exposure to foreign currencies and interest rates, sovereign debt, equity indices representing countries other than the U.S. and through exposure to companies (i) organized or located outside the U.S., (ii) whose primary trading market is located outside the U.S. or (iii) doing a substantial amount of business outside the U.S., which the Fund considers as a company that derives at least 50% of its revenue from business outside the U.S. or has at least 50% of its assets outside the U.S. The Fund will allocate its assets among various regions and countries, including the United States (but in no less than three different countries including the U.S.).

In seeking to achieve its investment objective, the Fund may enter into both “long” and “short” positions using derivative instruments. The Adviser generally expects that the Fund will have exposure in long and short positions across all four major asset classes (commodities, currencies, fixed income and equities), but at any one time the Fund may emphasize one or two of the asset classes or a limited number of exposures within an asset class.

The Fund invests primarily in a portfolio of futures contracts, futures-related instruments, forwards and swaps, including, but not limited to, global developed and emerging market equity index futures, swaps on equity index futures, equity swaps and options on equity indices, global developed and emerging market currency forwards, commodity futures and swaps, global developed fixed income futures, and bond and interest rate futures and swaps (collectively, the “Instruments”), either by investing directly in those Instruments, or indirectly by investing in the Subsidiary (as described below) that invests in those Instruments. The Fund may also invest in exchange traded funds or exchange traded notes.

Futures and forward contracts are contractual agreements to buy or sell a particular currency, commodity or financial instrument at a pre-determined price in the future. The Fund’s use of futures contracts, forward contracts, swaps and certain other Instruments will have the economic effect of financial leverage. Financial leverage magnifies exposure to the swings in prices of an asset class underlying an Instrument and results in increased volatility, which means the Fund will have the potential for greater gains, as well as the potential for greater losses, than if the Fund does not use Instruments that have a leveraging effect. Leveraging tends to magnify, sometimes significantly, the effect of any increase or decrease in the Fund’s exposure to an asset class and may cause the Fund’s NAV to be volatile. For example, if the Adviser seeks to gain enhanced exposure to a specific asset class through an Instrument providing leveraged exposure to the class and that Instrument increases in value, the gain to the Fund will be magnified; however, if that investment decreases in value, the loss to the Fund will be magnified. As a result of the Fund’s strategy, the Fund may have highly leveraged exposure to one or more asset classes at times. A decline in the Fund’s assets due to losses magnified by the Instruments providing leveraged exposure may require the Fund to liquidate portfolio positions to satisfy its obligations, to meet redemption requests or to meet asset segregation requirements when it may not be advantageous to do so. There is no assurance that the Fund’s use of Instruments providing enhanced exposure will enable the Fund to achieve its investment objective.

When taking into account Instruments and investments with a maturity of one year or less at the time of acquisition, the Fund’s strategy will result in frequent portfolio trading and high portfolio turnover (typically greater than 300%). The Adviser utilizes portfolio optimization techniques to determine the frequency of trading, taking into account the transaction costs associated with trading each Instrument. A higher portfolio turnover rate results in correspondingly greater brokerage commissions and other transactional expenses, which are borne by the Fund, and may have adverse tax consequences. The Fund employs sophisticated proprietary trading techniques in an effort to mitigate trading costs and execution impact on the Fund.

A significant portion of the assets of the Fund may be invested directly or indirectly in money market instruments, which may include, but are not limited to, U.S. Government securities, U.S. government agency securities, short-term fixed income securities, overnight and/or fixed term repurchase agreements, money market mutual fund shares, and cash and cash equivalents with one year or less term to maturity. These cash or cash equivalent holdings serve as collateral for the positions the Fund takes and also earn income for the Fund. While the Fund normally does not engage in any direct borrowing, leverage is implicit in the futures and other derivatives it trades.

The Fund intends to make investments through the Subsidiary and may invest up to 25% of its total assets in the Subsidiary. The Subsidiary is a wholly-owned and controlled subsidiary of the Fund, organized under the laws of the Cayman Islands as an exempted company. Generally, the Subsidiary will invest primarily in commodity futures, commodity forwards, commodity swaps, swaps on commodity futures and other commodity-linked derivative Instruments but it may also invest in financial futures, option and swap contracts, fixed income securities, pooled investment vehicles, including those that are not registered pursuant to the 1940 Act, and other investments intended to serve as margin or collateral for the Subsidiary’s derivative positions. The Fund will invest in the Subsidiary in order to gain exposure to the commodities markets within the limitations of the federal tax laws, rules and regulations that apply to registered investment companies. Unlike the Fund, the Subsidiary may invest without limitation in commodity-linked derivatives, however, the Subsidiary will comply with the same 1940 Act asset coverage requirements with respect to its investments in commodity-linked derivatives that are applicable to the Fund’s transactions in derivatives. In addition, to the extent applicable to the investment activities of the Subsidiary, the Subsidiary will be subject to the same fundamental investment restrictions and will follow the same compliance policies and procedures as the Fund. Unlike the Fund, the Subsidiary will not seek to qualify as a regulated investment company under Subchapter M of the Code. The Fund is the sole shareholder of the Subsidiary and does not expect shares of the Subsidiary to be offered or sold to other investors.

Principal Risks of Investing in the Fund

Risk is inherent in all investing. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The Fund is not a complete investment program and should be considered only as one part of an investment portfolio. The Fund is more appropriate for long-term investors who can bear the risk of short-term NAV fluctuations, which at times, may be significant and rapid. The following is a summary description of certain risks of investing in the Fund.

Commodities Risk: Exposure to the commodities markets may subject the Fund to greater volatility than investments in traditional securities. The value of commodity-linked derivative investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or sectors affecting a particular industry or commodity, such as drought, floods, weather, embargoes, tariffs and international economic, political and regulatory developments.

Common Stock Risk: The Fund may invest in, or have exposure to, common stocks. Common stocks are subject to greater fluctuations in market value than certain other asset classes as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

Counterparty Risk: The Fund may enter into various types of derivative contracts. Many of these derivative contracts may be privately negotiated in the over-the-counter market. These contracts also involve exposure to credit risk, since contract performance depends in part on the financial condition of the counterparty. If a privately negotiated over-the-counter contract calls for payments by the Fund, the Fund must be prepared to make such payments when due. In addition, if a counterparty’s creditworthiness declines, the Fund may not receive payments owed under the contract, or such payments may be delayed under such circumstances and the value of agreements with such counterparty can be expected to decline, potentially resulting in losses by the Fund.

Credit Risk: Credit risk refers to the possibility that the issuer of a security or the issuer of the reference asset of a derivative instrument will not be able to make principal and interest payments when due. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also affect the value of the Fund’s investment in that issuer. Securities rated in the four highest categories by the rating agencies are considered investment grade but they may also have some speculative characteristics. Investment grade ratings do not guarantee that bonds will not lose value.

Currency Risk: The risk that changes in currency exchange rates will negatively affect securities denominated in, and/or receiving revenues in, foreign currencies. The liquidity and trading value of foreign currencies could be affected by global economic factors, such as inflation, interest rate levels, and trade balances among countries, as well as the actions of sovereign governments and central banks. Adverse changes in currency exchange rates (relative to the U.S. dollar) may erode or reverse any potential gains from the Fund’s investments in securities denominated in a foreign currency or may widen existing losses. The Fund’s net currency positions may expose it to risks independent of its securities positions.

Derivatives Risk: In general, a derivative contract typically involves leverage, i.e., it provides exposure to potential gain or loss from a change in the level of the market price of the underlying security, currency or commodity (or a basket or index) in a notional amount that exceeds the amount of cash or assets required to establish or maintain the derivative contract. The use of derivative instruments also exposes the Fund to additional risks and transaction costs. Adverse changes in the value or level of the underlying asset or index can result in a loss to the Fund substantially greater than the amount invested in the derivative itself. These instruments come in many varieties and have a wide range of potential risks and rewards, and may include futures contracts, options, swaps and forwards. A risk of the Fund’s use of derivatives is that the fluctuations in their values may not correlate perfectly with the overall securities markets.

Emerging Market Risk: The Fund intends to have exposure to emerging markets. Emerging markets are riskier than more developed markets because they tend to develop unevenly and may never fully develop. Investments in emerging markets may be considered speculative. Emerging markets are more likely to experience hyperinflation and currency devaluations, which adversely affect returns to U.S. investors. In addition, many emerging securities markets have far lower trading volumes and less liquidity than developed markets.

Foreign Investments Risk: Foreign investments often involve special risks not present in U.S. investments that can increase the chances that the Fund will lose money. These risks include:

• The Fund generally holds its foreign securities and cash in foreign banks and securities depositories, which may be recently organized or new to the foreign custody business and may be subject to only limited or no regulatory oversight.

• Changes in foreign currency exchange rates can affect the value of the Fund’s portfolio.

• The economies of certain foreign markets may not compare favorably with the economy of the United States with respect to such issues as growth of gross national product, reinvestment of capital, resources and balance of payments position.

• The governments of certain countries may prohibit or impose substantial restrictions on foreign investments in their capital markets or in certain industries.

• Many foreign governments do not supervise and regulate stock exchanges, brokers and the sale of securities to the same extent as does the United States and may not have laws to protect investors that are comparable to U.S. securities laws.

• Settlement and clearance procedures in certain foreign markets may result in delays in payment for or delivery of securities not typically associated with settlement and clearance of U.S. investments.

Forward and Futures Contract Risk: The successful use of forward and futures contracts draws upon the Adviser’s skill and experience with respect to such instruments and are subject to special risk considerations. The primary risks associated with the use of forward and futures contracts, which may adversely affect the Fund’s NAV and total return, are (a) the imperfect correlation between the change in market value of the instruments held by the Fund and the price of the forward or futures contract; (b) possible lack of a liquid secondary market for a forward or futures contract and the resulting inability to close a forward or futures contract when desired; (c) losses caused by unanticipated market movements, which are potentially unlimited; (d) the Adviser’s inability to predict correctly the direction of securities prices, interest rates, currency exchange rates and other economic factors; (e) the possibility that the counterparty will default in the performance of its obligations; and (f) if the Fund has insufficient cash, it may have to sell securities from its portfolio to meet daily variation margin requirements, and the Fund may have to sell securities at a time when it may be disadvantageous to do so.

Hedging Transactions Risk: The Adviser from time to time employs various hedging techniques. The success of the Fund’s hedging strategy will be subject to the Adviser’s ability to correctly assess the degree of correlation between the performance of the instruments used in the hedging strategy and the performance of the investments in the portfolio being hedged. Since the characteristics of many securities change as markets change or time passes, the success of the Fund’s hedging strategy will also be subject to the Adviser’s ability to continually recalculate, readjust, and execute hedges in an efficient and timely manner. For a variety of reasons, the Adviser may not seek to establish a perfect correlation between such hedging instruments and the portfolio holdings being hedged. Such imperfect correlation may prevent the Fund from achieving the intended hedge or expose the Fund to risk of loss. In addition, it is not possible to hedge fully or perfectly against any risk, and hedging entails its own costs.

High Portfolio Turnover Risk: The investment techniques and strategies utilized by the Fund, including investments made on a shorter-term basis or in derivative instruments or instruments with a maturity of one year or less at the time of acquisition, will result in frequent portfolio trading and high portfolio turnover. High portfolio turnover rates will cause the Fund to incur higher levels of brokerage fees and commissions, which may reduce performance, and may cause higher levels of current tax liability to shareholders in the Fund.

Interest Rate Risk: Interest rate risk is the risk that prices of fixed income securities generally increase when interest rates decline and decrease when interest rates increase. The Fund may lose money if short term or long term interest rates rise sharply or otherwise change in a manner not anticipated by the Adviser.

Investment in Other Investment Companies Risk: As with other investments, investments in other investment companies, including exchange-traded funds (“ETFs”), are subject to market and selection risk. In addition, if the Fund acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Fund (including management and advisory fees) and, indirectly, the expenses of the investment companies. The Fund may invest in money market mutual funds. An investment in a money market mutual fund is not insured or guaranteed by a Federal Deposit Insurance Corporation or any other government agency. Although such funds seek to preserve the value of the Fund’s investment at $1.00 per share, it is possible to lose money by investing in a money market mutual fund.

Leverage Risk: As part of the Fund’s principal investment strategy, the Fund will make investments in futures contracts, forward contracts, options, swaps and other derivative instruments. These derivative instruments provide the economic effect of financial leverage by creating additional investment exposure, as well as the potential for greater loss. If the Fund uses leverage through purchasing derivative instruments, the Fund has the risk of capital losses that exceed the net assets of the Fund. The net asset value of a Fund employing leverage will be more volatile and sensitive to market movements. Leverage may involve the creation of a liability that requires the Fund to pay interest.

The 1940 Act and the rules and interpretations thereunder impose certain limitations on the Fund’s ability to use leverage; however, the Fund is not subject to any additional limitations on its net long and short exposures. For example, the Fund could hold instruments that provide five times the net return of a broad- or narrow-based securities index.

Manager Risk: If the Fund’s portfolio managers make poor investment decisions, it will negatively affect the Fund’s investment performance.

Market Risk: Market risk is the risk that the markets on which the Fund’s investments trade will increase or decrease in value. Prices may fluctuate widely over short or extended periods in response to company, market or economic news. Markets also tend to move in cycles, with periods of rising and falling prices. If there is a general decline in the securities and other markets, your investment in the Fund may lose value, regardless of the individual results of the securities and other instruments in which the Fund invests.

Mid Cap Securities Risk: The prices of securities of mid cap companies generally are more volatile than those of large capitalization companies and are more likely to be adversely affected than large cap companies by changes in earnings results and investor expectations or poor economic or market conditions, including those experienced during a recession.

Model and Data Risk: Given the complexity of the investments and strategies of the Fund, the Adviser relies heavily on quantitative models (both proprietary models developed by the Adviser, and those supplied by third parties) and information and data supplied by third parties (“Models and Data”). Models and Data are used to construct sets of transactions and investments, to provide risk management insights, and to assist in hedging the Fund’s investments.

When Models and Data prove to be incorrect or incomplete, any decisions made in reliance thereon expose the Fund to potential risks. Similarly, any hedging based on faulty Models and Data may prove to be unsuccessful. Some of the models used by the Adviser for the Fund are predictive in nature. The use of predictive models has inherent risks. Because predictive models are usually constructed based on historical data supplied by third parties, the success of relying on such models may depend heavily on the accuracy and reliability of the supplied historical data.

The Fund bears the risk that the proprietary quantitative models used by the portfolio managers will not be successful in identifying trends or in determining the size and direction of investment positions that will enable the Fund to achieve its investment objective.

All models rely on correct market data inputs. If incorrect market data is entered into even a well-founded model, the resulting information will be incorrect. However, even if market data is input correctly, “model prices” will often differ substantially from market prices, especially for instruments with complex characteristics, such as derivative instruments.

Momentum Style Risk: Investing in or having exposure to securities with positive momentum entails investing in securities that have had above-average recent returns. These securities may be more volatile than a broad cross-section of securities. In addition, there may be periods when the momentum style is out of favor, and during which the investment performance of a Fund using a momentum strategy may suffer.

New Fund Risk: The Fund is newly-formed. Accordingly, investors in the Fund bear the risk that the Fund may not be successful in implementing its investment strategy, and may not employ a successful investment strategy, any of which could result in the Fund being liquidated at any time without shareholder approval and at a time that may not be favorable for all shareholders. Such a liquidation could have negative tax consequences for shareholders.

Non-Diversified Status Risk: The Fund is a non-diversified fund. Because the Fund may invest in securities of a smaller number of issuers, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer than a fund that invests more widely, which may, therefore, have a greater impact on the Fund’s performance.

Options Risk: An option is an agreement that, for a premium payment or fee, gives the option holder (the purchaser) the right but not the obligation to buy (a “call option”) or sell (a “put option”) the underlying asset (or settle for cash an amount based on an underlying asset, rate, or index) at a specified price (the “exercise price”) during a period of time or on a specified date. Investments in options are considered speculative. When the Fund purchases an option, it may lose the premium paid for it if the price of the underlying security or other assets decreased or remained the same (in the case of a call option) or increased or remained the same (in the case of a put option). If a put or call option purchased by the Fund were permitted to expire without being sold or exercised, its premium would represent a loss to the Fund.

Short Sale Risk: The Fund may take a short position in a derivative instrument, such as a future, forward or swap. A short position on a derivative instrument involves the risk of a theoretically unlimited increase in the value of the underlying instrument. Short sales also involve transaction and other costs that will reduce potential Fund gains and increase potential Fund losses.

Small Cap Securities Risk: Investments in the stocks of companies with smaller market capitalizations involve higher risks in some respects than do investments in stocks of larger companies. For example, prices of such stocks are often more volatile than prices of large capitalization stocks. In addition, due to thin trading in some such stocks, an investment in these stocks may be more illiquid (i.e., harder to sell) than that of larger capitalization stocks. Smaller capitalization companies also fail more often than larger companies and may have more limited management and financial resources than larger companies.

Sovereign Debt Risk: The Fund may invest in, or have exposure to, sovereign debt instruments. These investments are subject to the risk that a governmental entity may delay or refuse to pay interest or repay principal on its sovereign debt, due, for example, to cash flow problems, insufficient foreign currency reserves, political considerations, the relative size of the governmental entity’s debt position in relation to the economy or the failure to put in place economic reforms required by the International Monetary Fund or other multilateral agencies. If a governmental entity defaults, it may ask for more time in which to pay or for further loans. There is no legal process for collecting sovereign debt that a government does not pay nor are there bankruptcy proceedings through which all or part of the sovereign debt that a governmental entity has not repaid may be collected.

Subsidiary Risk: By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The commodity-related instruments held by the Subsidiary are generally similar to those that are permitted to be held by the Fund and are subject to the same risks that apply to similar investments if held directly by the Fund. There can be no assurance that the investment objective of the Subsidiary will be achieved. The Subsidiary is not registered under the 1940 Act, and, unless otherwise noted in this prospectus, is not subject to all the investor protections of the 1940 Act. However, the Fund wholly owns and controls the Subsidiary, and the Fund and the Subsidiary are both managed by the Adviser, making it unlikely that the Subsidiary will take action contrary to the interests of the Fund and its shareholders. The Board of Trustees has oversight responsibility for the investment activities of the Fund, including its investment in the Subsidiary, and the Fund’s role as sole shareholder of the Subsidiary. To the extent applicable to the investment activities of the Subsidiary, the Subsidiary will be subject to the same investment restrictions and limitations, and follow the same compliance policies and procedures, as the Fund. Unlike the Fund, the Subsidiary will not seek to qualify as a regulated investment company under Subchapter M of the Code. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as described in this prospectus and the statement of additional information (“SAI”) and could adversely affect the Fund.

Swap Agreements Risk: Swap agreements involve the risk that the party with whom the Fund has entered into the swap will default on its obligation to pay the Fund and the risk that the Fund will not be able to meet its obligations to pay the other party to the agreement.

Tax Risk: In order for the Fund to qualify as a regulated investment company under Subchapter M of the Code, the Fund must derive at least 90 percent of its gross income each taxable year from qualifying income, which is described in more detail in the SAI. Income from certain commodity-linked derivative instruments in which the Fund invests is not considered qualifying income. The Fund will therefore restrict its income from direct investments in commodity-linked derivative instruments that do not generate qualifying income, such as commodity-linked swaps, to a maximum of 10 percent of its gross income.

The Fund’s investment in the Subsidiary is expected to provide the Fund with exposure to the commodities markets within the limitations of the federal tax requirements of Subchapter M. The Fund intends to request a private letter ruling from the Internal Revenue Service confirming that the annual net profit, if any, realized by the Subsidiary and imputed for income tax purposes to the Fund should constitute “qualifying income” for purposes of the Fund remaining qualified as a regulated investment company for U.S. federal income tax purposes. The Internal Revenue Service has indicated that the granting of private letter rulings like the one the Fund intends to request is currently suspended, pending further internal discussion. As a result, there can be no expectation that the Internal Revenue Service will grant the private letter ruling requested. If the Internal Revenue Service does not grant the private letter ruling request, there is a risk that the Internal Revenue Service could assert that the annual net profit realized by the Subsidiary and imputed for income tax purposes to the Fund will not be considered “qualifying income” for purposes of the Fund remaining qualified as a regulated investment company for U.S. federal income tax purposes. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or its Subsidiary to operate as described in this prospectus and the SAI and could adversely affect the Fund. For example, the Cayman Islands does not currently impose any income, corporate or capital gains tax, estate duty, inheritance tax, gift tax or withholding tax on the Subsidiary. If Cayman Islands law changes such that the Subsidiary must pay Cayman Islands taxes, Fund shareholders would likely suffer decreased investment returns.

U.S. Government Securities Risk: Treasury obligations may differ in their interest rates, maturities, times of issuance and other characteristics. Obligations of U.S. Government agencies and authorities are supported by varying degrees of credit but generally are not backed by the full faith and credit of the U.S. Government. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so. Certain of the government agency securities the Fund may purchase are backed only by the credit of the government agency and not by full faith and credit of the United States.

Value Style Risk: Investing in or having exposure to “value” stocks presents the risk that the stocks may never reach what the Adviser believes are their full market values, either because the market fails to recognize what the Adviser considers to be the companies’ true business values or because the Adviser misjudged those values. In addition, value stocks may fall out of favor with investors and underperform growth stocks during given periods.

Volatility Risk: The Fund may have investments that appreciate or decrease significantly in value over short periods of time. This may cause the Fund’s net asset value per share to experience significant increases or declines in value over short periods of time.

[1] Other expenses are estimated for the current fiscal year because the Fund had not commenced operations as of the date of this prospectus.

[2] The Adviser has contractually agreed to waive its management fee and/or to reimburse expenses of the Fund to the extent necessary to maintain the total annual fund operating expenses (excluding interest, taxes, dividends on short sales, borrowing costs, acquired fund fees and expenses, interest expense relating to short sales and extraordinary expenses) at no more than 1.45% for Class I Shares and 1.70% for Class N Shares (the "Fee Waiver Agreement"). This arrangement will continue at least through April 30, 2016. The Fee Waiver Agreement may only be terminated with the consent of the Board of Trustees, including a majority of the Trustees of the Trust who are not "interested persons" of the Trust within the meaning of the 1940 Act. Under the Fee Waiver Agreement, the Adviser is entitled to recapture the fees waived and/or expenses reimbursed, only to the extent that such recapture can be made during the thirty-six months following the applicable period during which the Adviser waived fees or reimbursed expenses. In no case will the Adviser recapture any amount that would cause the aggregate operating expenses of the Fund attributable to a share class during a year in which a repayment is made to exceed the applicable limits described above during such year.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies of the Fund
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund pursues its investment objective by investing globally across a wide range of asset classes, including equities, fixed income, currencies and commodities, and may take both “long” and “short” positions in each of the asset classes or Instruments (as defined below). The Fund has the flexibility to shift its allocation across asset classes and markets around the world, including emerging markets, based on the Adviser’s assessment of their relative attractiveness. The Adviser uses a bottom up systematic process that considers four primary indicators of attractiveness in determining whether to take a long or short position in an Instrument or asset class: macroeconomic data, value, momentum, and carry. Macroeconomic Data: The Adviser seeks to evaluate the impact of macroeconomic news and macroeconomic momentum on the attractiveness of Instruments and asset classes around the world. Macroeconomic themes considered include, but are not limited to, business cycles, international trade, monetary policy, investor sentiment and asset-specific fundamentals. The evaluation of macroeconomic attractiveness includes both quantitative and qualitative components. Quantitative analysis measures an Instrument’s attractiveness based on the current level and historical evolution of key macroeconomic measures. These measures include, but are not limited to, growth and inflation forecasts, demand for exports, central bank actions and equity market performance. Qualitative input adds a perspective not available through quantitative analysis. These considerations include, but are not limited to, the Adviser’s assessment of fiscal and monetary policy, trade policy, geo-political risks and supply-and-demand conditions. The Adviser combines the quantitative and qualitative components into an overall indicator of the macroeconomic attractiveness of an Instrument or asset class. When the quantitative and qualitative assessments agree, the long or short position in an Instrument or asset class will be given greater weighting within the portfolio, while conflicting assessments will result in a lesser weighting. Value: Value strategies favor investments that appear cheap over those that appear expensive based on fundamental measures related to price, seeking to capture the tendency for relatively cheap assets to outperform relatively expensive assets. The Fund will seek to buy assets that are cheap and sell those that are expensive relative to similar investments globally and relative to their historical averages. Examples of value measures include using price-to-earnings and price-to-book ratios for selecting equities. Momentum: Momentum strategies favor investments that have performed relatively well over those that have underperformed over the medium-term, seeking to capture the tendency that an asset’s recent performance will continue in the near future. The Fund will seek to buy assets that recently outperformed and sell those that recently underperformed relative to similar investments globally and relative to their historical averages. Examples of momentum measures include simple price momentum for selecting equities and price- and yield-based momentum for selecting bonds. Carry: Carry strategies favor investments with higher yields over those with lower yields, seeking to capture the tendency for higher yielding assets to provide higher returns than lower-yielding assets. The Fund will seek to buy high-yielding assets and sell low-yielding assets relative to similar investments globally and relative to their historical averages. An example of carry measures includes using interest rates to select currencies and bonds. Portfolio Construction Each of the four primary indicators of attractiveness (macroeconomic data, value, momentum and carry) is taken into consideration in determining whether the portfolio’s position in the Instrument in question should be long or short. The owner of a “long” position in an Instrument will benefit from an increase in the price of the underlying security or instrument. The owner of a “short” position in an Instrument will benefit from a decrease in the price of the underlying security or instrument. The Fund goes long Instruments deemed overall attractive, and short Instruments deemed overall unattractive. When there is strong agreement among the four indicators, the long or short position in an Instrument or asset class will be given a greater weighting in the portfolio, while conflicting indicators will result in a lesser weighting. Individual investments are bought or sold in accordance with periodic re-ranking and rebalancing, the frequency of which is expected to vary depending on the Adviser’s assessment of the investment’s attractiveness and global market conditions. The Adviser allocates among the different asset classes based on their contribution to the Fund’s risk budget—i.e., the targeted level of risk or volatility. The allocation process allows the Adviser to make tactical risk adjustments while maintaining long-term strategic risk weights. Within each asset class, approximately 50% of the Fund’s target risk is expected to be allocated based on the macroeconomic indicators, and the remaining 50% of target risk is expected to be allocated based on the value, momentum, and carry indicators. These relative weights, and the relative weights to each of the value, momentum and carry indicators, can vary depending on market conditions. The Adviser generally expects that the Fund’s performance will have a low correlation to the performance of the general global equity, fixed income, currency and commodity markets over any given market cycle; however, the Fund’s performance may correlate to the performance of any one or more of those markets over short-term periods. The Adviser will use quantitative and qualitative methods to assess the level of risk (i.e., volatility of return) for the Fund. Volatility is a statistical measurement of the dispersion of returns of a security or fund or index, as measured by the annualized standard deviation of its returns. Higher volatility generally indicates higher risk. The Fund’s returns are expected to be volatile because of the significant use of Instruments that have a leveraging effect; however, the Adviser, on average, will target an annualized volatility level for the Fund of 10%. The Adviser expects that the Fund’s targeted annualized forecasted volatility will typically range between 5% and 15%; however, the actual or realized volatility level for longer or shorter periods may be materially higher or lower depending on market conditions. Actual or realized volatility can and will differ from the forecasted or target volatility described above. Instruments Generally, the Fund will invest in Instruments providing exposure to a number of different countries throughout the world, one of which may be the United States. Under normal circumstances, the Fund will invest significantly (at least 40%, unless market conditions are not deemed favorable by the Adviser in which case the Fund would invest at least 30%) outside the U.S., primarily through exposure to foreign currencies and interest rates, sovereign debt, equity indices representing countries other than the U.S. and through exposure to companies (i) organized or located outside the U.S., (ii) whose primary trading market is located outside the U.S. or (iii) doing a substantial amount of business outside the U.S., which the Fund considers as a company that derives at least 50% of its revenue from business outside the U.S. or has at least 50% of its assets outside the U.S. The Fund will allocate its assets among various regions and countries, including the United States (but in no less than three different countries including the U.S.). In seeking to achieve its investment objective, the Fund may enter into both “long” and “short” positions using derivative instruments. The Adviser generally expects that the Fund will have exposure in long and short positions across all four major asset classes (commodities, currencies, fixed income and equities), but at any one time the Fund may emphasize one or two of the asset classes or a limited number of exposures within an asset class. The Fund invests primarily in a portfolio of futures contracts, futures-related instruments, forwards and swaps, including, but not limited to, global developed and emerging market equity index futures, swaps on equity index futures, equity swaps and options on equity indices, global developed and emerging market currency forwards, commodity futures and swaps, global developed fixed income futures, and bond and interest rate futures and swaps (collectively, the “Instruments”), either by investing directly in those Instruments, or indirectly by investing in the Subsidiary (as described below) that invests in those Instruments. The Fund may also invest in exchange traded funds or exchange traded notes. Futures and forward contracts are contractual agreements to buy or sell a particular currency, commodity or financial instrument at a pre-determined price in the future. The Fund’s use of futures contracts, forward contracts, swaps and certain other Instruments will have the economic effect of financial leverage. Financial leverage magnifies exposure to the swings in prices of an asset class underlying an Instrument and results in increased volatility, which means the Fund will have the potential for greater gains, as well as the potential for greater losses, than if the Fund does not use Instruments that have a leveraging effect. Leveraging tends to magnify, sometimes significantly, the effect of any increase or decrease in the Fund’s exposure to an asset class and may cause the Fund’s NAV to be volatile. For example, if the Adviser seeks to gain enhanced exposure to a specific asset class through an Instrument providing leveraged exposure to the class and that Instrument increases in value, the gain to the Fund will be magnified; however, if that investment decreases in value, the loss to the Fund will be magnified. As a result of the Fund’s strategy, the Fund may have highly leveraged exposure to one or more asset classes at times. A decline in the Fund’s assets due to losses magnified by the Instruments providing leveraged exposure may require the Fund to liquidate portfolio positions to satisfy its obligations, to meet redemption requests or to meet asset segregation requirements when it may not be advantageous to do so. There is no assurance that the Fund’s use of Instruments providing enhanced exposure will enable the Fund to achieve its investment objective. When taking into account Instruments and investments with a maturity of one year or less at the time of acquisition, the Fund’s strategy will result in frequent portfolio trading and high portfolio turnover (typically greater than 300%). The Adviser utilizes portfolio optimization techniques to determine the frequency of trading, taking into account the transaction costs associated with trading each Instrument. A higher portfolio turnover rate results in correspondingly greater brokerage commissions and other transactional expenses, which are borne by the Fund, and may have adverse tax consequences. The Fund employs sophisticated proprietary trading techniques in an effort to mitigate trading costs and execution impact on the Fund. A significant portion of the assets of the Fund may be invested directly or indirectly in money market instruments, which may include, but are not limited to, U.S. Government securities, U.S. government agency securities, short-term fixed income securities, overnight and/or fixed term repurchase agreements, money market mutual fund shares, and cash and cash equivalents with one year or less term to maturity. These cash or cash equivalent holdings serve as collateral for the positions the Fund takes and also earn income for the Fund. While the Fund normally does not engage in any direct borrowing, leverage is implicit in the futures and other derivatives it trades. The Fund intends to make investments through the Subsidiary and may invest up to 25% of its total assets in the Subsidiary. The Subsidiary is a wholly-owned and controlled subsidiary of the Fund, organized under the laws of the Cayman Islands as an exempted company. Generally, the Subsidiary will invest primarily in commodity futures, commodity forwards, commodity swaps, swaps on commodity futures and other commodity-linked derivative Instruments but it may also invest in financial futures, option and swap contracts, fixed income securities, pooled investment vehicles, including those that are not registered pursuant to the 1940 Act, and other investments intended to serve as margin or collateral for the Subsidiary’s derivative positions. The Fund will invest in the Subsidiary in order to gain exposure to the commodities markets within the limitations of the federal tax laws, rules and regulations that apply to registered investment companies. Unlike the Fund, the Subsidiary may invest without limitation in commodity-linked derivatives, however, the Subsidiary will comply with the same 1940 Act asset coverage requirements with respect to its investments in commodity-linked derivatives that are applicable to the Fund’s transactions in derivatives. In addition, to the extent applicable to the investment activities of the Subsidiary, the Subsidiary will be subject to the same fundamental investment restrictions and will follow the same compliance policies and procedures as the Fund. Unlike the Fund, the Subsidiary will not seek to qualify as a regulated investment company under Subchapter M of the Code. The Fund is the sole shareholder of the Subsidiary and does not expect shares of the Subsidiary to be offered or sold to other investors.
Risk [Heading]	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Risk is inherent in all investing. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The Fund is not a complete investment program and should be considered only as one part of an investment portfolio. The Fund is more appropriate for long-term investors who can bear the risk of short-term NAV fluctuations, which at times, may be significant and rapid. The following is a summary description of certain risks of investing in the Fund. Commodities Risk: Exposure to the commodities markets may subject the Fund to greater volatility than investments in traditional securities. The value of commodity-linked derivative investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or sectors affecting a particular industry or commodity, such as drought, floods, weather, embargoes, tariffs and international economic, political and regulatory developments. Common Stock Risk: The Fund may invest in, or have exposure to, common stocks. Common stocks are subject to greater fluctuations in market value than certain other asset classes as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions. Counterparty Risk: The Fund may enter into various types of derivative contracts. Many of these derivative contracts may be privately negotiated in the over-the-counter market. These contracts also involve exposure to credit risk, since contract performance depends in part on the financial condition of the counterparty. If a privately negotiated over-the-counter contract calls for payments by the Fund, the Fund must be prepared to make such payments when due. In addition, if a counterparty’s creditworthiness declines, the Fund may not receive payments owed under the contract, or such payments may be delayed under such circumstances and the value of agreements with such counterparty can be expected to decline, potentially resulting in losses by the Fund. Credit Risk: Credit risk refers to the possibility that the issuer of a security or the issuer of the reference asset of a derivative instrument will not be able to make principal and interest payments when due. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also affect the value of the Fund’s investment in that issuer. Securities rated in the four highest categories by the rating agencies are considered investment grade but they may also have some speculative characteristics. Investment grade ratings do not guarantee that bonds will not lose value. Currency Risk: The risk that changes in currency exchange rates will negatively affect securities denominated in, and/or receiving revenues in, foreign currencies. The liquidity and trading value of foreign currencies could be affected by global economic factors, such as inflation, interest rate levels, and trade balances among countries, as well as the actions of sovereign governments and central banks. Adverse changes in currency exchange rates (relative to the U.S. dollar) may erode or reverse any potential gains from the Fund’s investments in securities denominated in a foreign currency or may widen existing losses. The Fund’s net currency positions may expose it to risks independent of its securities positions. Derivatives Risk: In general, a derivative contract typically involves leverage, i.e., it provides exposure to potential gain or loss from a change in the level of the market price of the underlying security, currency or commodity (or a basket or index) in a notional amount that exceeds the amount of cash or assets required to establish or maintain the derivative contract. The use of derivative instruments also exposes the Fund to additional risks and transaction costs. Adverse changes in the value or level of the underlying asset or index can result in a loss to the Fund substantially greater than the amount invested in the derivative itself. These instruments come in many varieties and have a wide range of potential risks and rewards, and may include futures contracts, options, swaps and forwards. A risk of the Fund’s use of derivatives is that the fluctuations in their values may not correlate perfectly with the overall securities markets. Emerging Market Risk: The Fund intends to have exposure to emerging markets. Emerging markets are riskier than more developed markets because they tend to develop unevenly and may never fully develop. Investments in emerging markets may be considered speculative. Emerging markets are more likely to experience hyperinflation and currency devaluations, which adversely affect returns to U.S. investors. In addition, many emerging securities markets have far lower trading volumes and less liquidity than developed markets. Foreign Investments Risk: Foreign investments often involve special risks not present in U.S. investments that can increase the chances that the Fund will lose money. These risks include: The Fund generally holds its foreign securities and cash in foreign banks and securities depositories, which may be recently organized or new to the foreign custody business and may be subject to only limited or no regulatory oversight. Changes in foreign currency exchange rates can affect the value of the Fund’s portfolio. The economies of certain foreign markets may not compare favorably with the economy of the United States with respect to such issues as growth of gross national product, reinvestment of capital, resources and balance of payments position. The governments of certain countries may prohibit or impose substantial restrictions on foreign investments in their capital markets or in certain industries. Many foreign governments do not supervise and regulate stock exchanges, brokers and the sale of securities to the same extent as does the United States and may not have laws to protect investors that are comparable to U.S. securities laws. Settlement and clearance procedures in certain foreign markets may result in delays in payment for or delivery of securities not typically associated with settlement and clearance of U.S. investments. Forward and Futures Contract Risk: The successful use of forward and futures contracts draws upon the Adviser’s skill and experience with respect to such instruments and are subject to special risk considerations. The primary risks associated with the use of forward and futures contracts, which may adversely affect the Fund’s NAV and total return, are (a) the imperfect correlation between the change in market value of the instruments held by the Fund and the price of the forward or futures contract; (b) possible lack of a liquid secondary market for a forward or futures contract and the resulting inability to close a forward or futures contract when desired; (c) losses caused by unanticipated market movements, which are potentially unlimited; (d) the Adviser’s inability to predict correctly the direction of securities prices, interest rates, currency exchange rates and other economic factors; (e) the possibility that the counterparty will default in the performance of its obligations; and (f) if the Fund has insufficient cash, it may have to sell securities from its portfolio to meet daily variation margin requirements, and the Fund may have to sell securities at a time when it may be disadvantageous to do so. Hedging Transactions Risk: The Adviser from time to time employs various hedging techniques. The success of the Fund’s hedging strategy will be subject to the Adviser’s ability to correctly assess the degree of correlation between the performance of the instruments used in the hedging strategy and the performance of the investments in the portfolio being hedged. Since the characteristics of many securities change as markets change or time passes, the success of the Fund’s hedging strategy will also be subject to the Adviser’s ability to continually recalculate, readjust, and execute hedges in an efficient and timely manner. For a variety of reasons, the Adviser may not seek to establish a perfect correlation between such hedging instruments and the portfolio holdings being hedged. Such imperfect correlation may prevent the Fund from achieving the intended hedge or expose the Fund to risk of loss. In addition, it is not possible to hedge fully or perfectly against any risk, and hedging entails its own costs. High Portfolio Turnover Risk: The investment techniques and strategies utilized by the Fund, including investments made on a shorter-term basis or in derivative instruments or instruments with a maturity of one year or less at the time of acquisition, will result in frequent portfolio trading and high portfolio turnover. High portfolio turnover rates will cause the Fund to incur higher levels of brokerage fees and commissions, which may reduce performance, and may cause higher levels of current tax liability to shareholders in the Fund. Interest Rate Risk: Interest rate risk is the risk that prices of fixed income securities generally increase when interest rates decline and decrease when interest rates increase. The Fund may lose money if short term or long term interest rates rise sharply or otherwise change in a manner not anticipated by the Adviser. Investment in Other Investment Companies Risk: As with other investments, investments in other investment companies, including exchange-traded funds (“ETFs”), are subject to market and selection risk. In addition, if the Fund acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Fund (including management and advisory fees) and, indirectly, the expenses of the investment companies. The Fund may invest in money market mutual funds. An investment in a money market mutual fund is not insured or guaranteed by a Federal Deposit Insurance Corporation or any other government agency. Although such funds seek to preserve the value of the Fund’s investment at $1.00 per share, it is possible to lose money by investing in a money market mutual fund. Leverage Risk: As part of the Fund’s principal investment strategy, the Fund will make investments in futures contracts, forward contracts, options, swaps and other derivative instruments. These derivative instruments provide the economic effect of financial leverage by creating additional investment exposure, as well as the potential for greater loss. If the Fund uses leverage through purchasing derivative instruments, the Fund has the risk of capital losses that exceed the net assets of the Fund. The net asset value of a Fund employing leverage will be more volatile and sensitive to market movements. Leverage may involve the creation of a liability that requires the Fund to pay interest. The 1940 Act and the rules and interpretations thereunder impose certain limitations on the Fund’s ability to use leverage; however, the Fund is not subject to any additional limitations on its net long and short exposures. For example, the Fund could hold instruments that provide five times the net return of a broad- or narrow-based securities index. Manager Risk: If the Fund’s portfolio managers make poor investment decisions, it will negatively affect the Fund’s investment performance. Market Risk: Market risk is the risk that the markets on which the Fund’s investments trade will increase or decrease in value. Prices may fluctuate widely over short or extended periods in response to company, market or economic news. Markets also tend to move in cycles, with periods of rising and falling prices. If there is a general decline in the securities and other markets, your investment in the Fund may lose value, regardless of the individual results of the securities and other instruments in which the Fund invests. Mid Cap Securities Risk: The prices of securities of mid cap companies generally are more volatile than those of large capitalization companies and are more likely to be adversely affected than large cap companies by changes in earnings results and investor expectations or poor economic or market conditions, including those experienced during a recession. Model and Data Risk: Given the complexity of the investments and strategies of the Fund, the Adviser relies heavily on quantitative models (both proprietary models developed by the Adviser, and those supplied by third parties) and information and data supplied by third parties (“Models and Data”). Models and Data are used to construct sets of transactions and investments, to provide risk management insights, and to assist in hedging the Fund’s investments. When Models and Data prove to be incorrect or incomplete, any decisions made in reliance thereon expose the Fund to potential risks. Similarly, any hedging based on faulty Models and Data may prove to be unsuccessful. Some of the models used by the Adviser for the Fund are predictive in nature. The use of predictive models has inherent risks. Because predictive models are usually constructed based on historical data supplied by third parties, the success of relying on such models may depend heavily on the accuracy and reliability of the supplied historical data. The Fund bears the risk that the proprietary quantitative models used by the portfolio managers will not be successful in identifying trends or in determining the size and direction of investment positions that will enable the Fund to achieve its investment objective. All models rely on correct market data inputs. If incorrect market data is entered into even a well-founded model, the resulting information will be incorrect. However, even if market data is input correctly, “model prices” will often differ substantially from market prices, especially for instruments with complex characteristics, such as derivative instruments. Momentum Style Risk: Investing in or having exposure to securities with positive momentum entails investing in securities that have had above-average recent returns. These securities may be more volatile than a broad cross-section of securities. In addition, there may be periods when the momentum style is out of favor, and during which the investment performance of a Fund using a momentum strategy may suffer. New Fund Risk: The Fund is newly-formed. Accordingly, investors in the Fund bear the risk that the Fund may not be successful in implementing its investment strategy, and may not employ a successful investment strategy, any of which could result in the Fund being liquidated at any time without shareholder approval and at a time that may not be favorable for all shareholders. Such a liquidation could have negative tax consequences for shareholders. Non-Diversified Status Risk: The Fund is a non-diversified fund. Because the Fund may invest in securities of a smaller number of issuers, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer than a fund that invests more widely, which may, therefore, have a greater impact on the Fund’s performance. Options Risk: An option is an agreement that, for a premium payment or fee, gives the option holder (the purchaser) the right but not the obligation to buy (a “call option”) or sell (a “put option”) the underlying asset (or settle for cash an amount based on an underlying asset, rate, or index) at a specified price (the “exercise price”) during a period of time or on a specified date. Investments in options are considered speculative. When the Fund purchases an option, it may lose the premium paid for it if the price of the underlying security or other assets decreased or remained the same (in the case of a call option) or increased or remained the same (in the case of a put option). If a put or call option purchased by the Fund were permitted to expire without being sold or exercised, its premium would represent a loss to the Fund. Short Sale Risk: The Fund may take a short position in a derivative instrument, such as a future, forward or swap. A short position on a derivative instrument involves the risk of a theoretically unlimited increase in the value of the underlying instrument. Short sales also involve transaction and other costs that will reduce potential Fund gains and increase potential Fund losses. Small Cap Securities Risk: Investments in the stocks of companies with smaller market capitalizations involve higher risks in some respects than do investments in stocks of larger companies. For example, prices of such stocks are often more volatile than prices of large capitalization stocks. In addition, due to thin trading in some such stocks, an investment in these stocks may be more illiquid (i.e., harder to sell) than that of larger capitalization stocks. Smaller capitalization companies also fail more often than larger companies and may have more limited management and financial resources than larger companies. Sovereign Debt Risk: The Fund may invest in, or have exposure to, sovereign debt instruments. These investments are subject to the risk that a governmental entity may delay or refuse to pay interest or repay principal on its sovereign debt, due, for example, to cash flow problems, insufficient foreign currency reserves, political considerations, the relative size of the governmental entity’s debt position in relation to the economy or the failure to put in place economic reforms required by the International Monetary Fund or other multilateral agencies. If a governmental entity defaults, it may ask for more time in which to pay or for further loans. There is no legal process for collecting sovereign debt that a government does not pay nor are there bankruptcy proceedings through which all or part of the sovereign debt that a governmental entity has not repaid may be collected. Subsidiary Risk: By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The commodity-related instruments held by the Subsidiary are generally similar to those that are permitted to be held by the Fund and are subject to the same risks that apply to similar investments if held directly by the Fund. There can be no assurance that the investment objective of the Subsidiary will be achieved. The Subsidiary is not registered under the 1940 Act, and, unless otherwise noted in this prospectus, is not subject to all the investor protections of the 1940 Act. However, the Fund wholly owns and controls the Subsidiary, and the Fund and the Subsidiary are both managed by the Adviser, making it unlikely that the Subsidiary will take action contrary to the interests of the Fund and its shareholders. The Board of Trustees has oversight responsibility for the investment activities of the Fund, including its investment in the Subsidiary, and the Fund’s role as sole shareholder of the Subsidiary. To the extent applicable to the investment activities of the Subsidiary, the Subsidiary will be subject to the same investment restrictions and limitations, and follow the same compliance policies and procedures, as the Fund. Unlike the Fund, the Subsidiary will not seek to qualify as a regulated investment company under Subchapter M of the Code. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as described in this prospectus and the statement of additional information (“SAI”) and could adversely affect the Fund. Swap Agreements Risk: Swap agreements involve the risk that the party with whom the Fund has entered into the swap will default on its obligation to pay the Fund and the risk that the Fund will not be able to meet its obligations to pay the other party to the agreement. Tax Risk: In order for the Fund to qualify as a regulated investment company under Subchapter M of the Code, the Fund must derive at least 90 percent of its gross income each taxable year from qualifying income, which is described in more detail in the SAI. Income from certain commodity-linked derivative instruments in which the Fund invests is not considered qualifying income. The Fund will therefore restrict its income from direct investments in commodity-linked derivative instruments that do not generate qualifying income, such as commodity-linked swaps, to a maximum of 10 percent of its gross income. The Fund’s investment in the Subsidiary is expected to provide the Fund with exposure to the commodities markets within the limitations of the federal tax requirements of Subchapter M. The Fund intends to request a private letter ruling from the Internal Revenue Service confirming that the annual net profit, if any, realized by the Subsidiary and imputed for income tax purposes to the Fund should constitute “qualifying income” for purposes of the Fund remaining qualified as a regulated investment company for U.S. federal income tax purposes. The Internal Revenue Service has indicated that the granting of private letter rulings like the one the Fund intends to request is currently suspended, pending further internal discussion. As a result, there can be no expectation that the Internal Revenue Service will grant the private letter ruling requested. If the Internal Revenue Service does not grant the private letter ruling request, there is a risk that the Internal Revenue Service could assert that the annual net profit realized by the Subsidiary and imputed for income tax purposes to the Fund will not be considered “qualifying income” for purposes of the Fund remaining qualified as a regulated investment company for U.S. federal income tax purposes. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or its Subsidiary to operate as described in this prospectus and the SAI and could adversely affect the Fund. For example, the Cayman Islands does not currently impose any income, corporate or capital gains tax, estate duty, inheritance tax, gift tax or withholding tax on the Subsidiary. If Cayman Islands law changes such that the Subsidiary must pay Cayman Islands taxes, Fund shareholders would likely suffer decreased investment returns. U.S. Government Securities Risk: Treasury obligations may differ in their interest rates, maturities, times of issuance and other characteristics. Obligations of U.S. Government agencies and authorities are supported by varying degrees of credit but generally are not backed by the full faith and credit of the U.S. Government. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so. Certain of the government agency securities the Fund may purchase are backed only by the credit of the government agency and not by full faith and credit of the United States. Value Style Risk: Investing in or having exposure to “value” stocks presents the risk that the stocks may never reach what the Adviser believes are their full market values, either because the market fails to recognize what the Adviser considers to be the companies’ true business values or because the Adviser misjudged those values. In addition, value stocks may fall out of favor with investors and underperform growth stocks during given periods. Volatility Risk: The Fund may have investments that appreciate or decrease significantly in value over short periods of time. This may cause the Fund’s net asset value per share to experience significant increases or declines in value over short periods of time.
Risk Lose Money [Text]	rr_RiskLoseMoney	You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments.
Risk Nondiversified Status [Text]	rr_RiskNondiversifiedStatus	Non-Diversified Status Risk: The Fund is a non-diversified fund. Because the Fund may invest in securities of a smaller number of issuers, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer than a fund that invests more widely, which may, therefore, have a greater impact on the Fund’s performance.
Risk Not Insured Depository Institution [Text]	rr_RiskNotInsuredDepositoryInstitution	An investment in a money market mutual fund is not insured or guaranteed by a Federal Deposit Insurance Corporation or any other government agency.

[1] Other expenses are estimated for the current fiscal year because the Fund had not commenced operations as of the date of this prospectus.

[2] The Adviser has contractually agreed to waive its management fee and/or to reimburse expenses of the Fund to the extent necessary to maintain the total annual fund operating expenses (excluding interest, taxes, dividends on short sales, borrowing costs, acquired fund fees and expenses, interest expense relating to short sales and extraordinary expenses) at no more than 1.45% for Class I Shares and 1.70% for Class N Shares (the "Fee Waiver Agreement"). This arrangement will continue at least through April 30, 2016. The Fee Waiver Agreement may only be terminated with the consent of the Board of Trustees, including a majority of the Trustees of the Trust who are not "interested persons" of the Trust within the meaning of the 1940 Act. Under the Fee Waiver Agreement, the Adviser is entitled to recapture the fees waived and/or expenses reimbursed, only to the extent that such recapture can be made during the thirty-six months following the applicable period during which the Adviser waived fees or reimbursed expenses. In no case will the Adviser recapture any amount that would cause the aggregate operating expenses of the Fund attributable to a share class during a year in which a repayment is made to exceed the applicable limits described above during such year.
