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 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 annual fund operating expenses, or in the Example, affect the Fund’s performance.

What are the Fund’s main investment strategies?

The Fund will seek to achieve its investment objective by allocating assets using a risk-parity approach. In determining portfolio construction, J.P. Morgan Investment Management Inc., the Fund’s investment adviser (the Adviser), has identified a set of market-driven investment return sources that have a low correlation to each other and unique risk and return profiles (each a “return factor”). The Adviser believes that, in general, a portfolio’s market-driven returns are attributable to the individual contributions of various return factors. By employing a return factor-based approach, the Adviser believes it can identify the desired return factors and construct a portfolio to “diversify the risk” to which the Fund is exposed while also providing enhanced risk-adjusted returns relative to a conventional asset allocation strategy. The Adviser will seek to capture these market-driven investment contributions by using a proprietary investment model to allocate assets to alternative and traditional investment strategies in order to gain targeted investment exposure to each of these selected return factors.

In determining asset allocation, a traditional risk-parity approach seeks to balance the allocation of risk (as measured by volatility) across asset classes, so that higher risk asset classes (e.g., equities) have lower allocations than lower risk asset classes (e.g., debt securities) within the portfolio. In general, an investor’s potential return on an investment is tied to the risk of the investment. Higher risk investments generally provide the potential for higher gains (or losses) while lower risk investments generally provide the potential for lower losses (or gains). Risk-parity investing seeks to equalize a portfolio’s risk level between the higher risk asset classes and the lower risk asset classes in an effort to provide more consistent risk-adjusted return levels. The Fund will use a risk-parity approach but will focus on diversifying across return factors rather than asset classes. The return factors identified by the Adviser fall into the following broad categories: equity based return factors, fixed income based return factors, convertible bond based return factors, real estate based return factors, currency based return factors and commodity based return factors. The Adviser will seek to maintain an approximately, equally weighted exposure (as measured by volatility) to each of the individual return factors, so that each return factor contributes equally to the Fund’s overall volatility over the long term. The exposure to individual return factors, however, may vary over the shorter term based on the opportunity the Adviser sees in each individual return factor.

The Fund will invest its assets globally (including in emerging markets) in various instruments, including equity securities, debt securities (including below investment grade and unrated debt securities), convertible securities, real estate investment trusts (REITs), commodities and currencies. The Fund will use derivatives instruments in investing its assets, including swaps, options, futures and forward contracts. The Fund will also engage in short sales, including through swaps. As a result of the Fund’s use of derivatives and to serve as collateral, the Fund may hold significant amounts of U.S. Treasury obligations, including Treasury bills, bonds and notes and other obligations issued or guaranteed by the U.S. Treasury, other short-term investments, including money market funds and foreign currencies. The Fund may also invest in exchange traded funds and other investment companies.

The amount that may be invested in any one instrument will vary and generally depend on the investment strategies employed by the Adviser at that time. However, there are no stated percentage limitations on the amount that can be invested in any one type of instrument and the Adviser may, at times, focus on a small number of instruments. Moreover, the Fund is generally unconstrained by any particular capitalization, style or sector and may invest in any region or country, including emerging markets.

The Fund will purchase a particular instrument when the Adviser believes that such instrument will allow the Fund to gain the desired exposure to a return factor. Conversely, the Fund will consider selling a particular instrument when it no longer provides the desired exposure to a return factor. In addition, investment decisions will take into account a return factor’s expected contribution to the Fund’s overall volatility.

The alternative investment strategies the Fund may use include equity market neutral, event driven, convertible arbitrage, relative value fixed income and currency and relative value commodity, and the traditional investment strategies include long only investing in equity securities, fixed-income securities, REITs, commodities and currencies.

The Fund will gain exposure to commodity markets by investing up to 15% of its total assets in commodity related instruments either directly or indirectly through the JPM Diversified Risk Fund Ltd., a wholly owned subsidiary of the Fund organized under the laws of the Cayman Islands (the Subsidiary). The Subsidiary is also advised by the Adviser. The Subsidiary (unlike the Fund) may invest without limitation in commodity related investments, including commodity-linked swap agreements and other commodity-linked derivative instruments, such as those linked to the value of a particular commodity, commodity index or commodity futures contract, or a subset of commodities or commodity futures contracts. The Subsidiary is otherwise subject to the same fundamental, non-fundamental and certain other investment restrictions as the Fund.

There can be no assurance that employing a “diversified risk” approach will achieve any particular level of return or will, in fact, reduce volatility or potential loss.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. Equity securities are subject to “stock market risk” meaning that stock prices in general (or in particular, the prices of the types of securities in which a Fund invests) may decline over short or extended periods of time. When the value of the Fund’s securities goes down, the value of your investment in the Fund will be affected.

Model Risk. There can be no assurance that employing a “risk parity” approach to determine the weighting of return factors in the Fund’s portfolio will achieve any particular level of return, or will, in fact, reduce volatility or potential loss. In addition, given the complexity of the investment strategies, the Adviser will make use of quantitative models to, among other things, help determine the portfolio’s asset allocation weightings. To the extent the models used by the Adviser are incorrect or incomplete, the decisions made by the Adviser in reliance thereon will expose the Fund to potential risks.

Alternative Strategies Risk. The Fund will employ various alternative investment strategies that involve the use of complicated investment techniques. There is no guarantee that these strategies will succeed and their use may subject the Fund to greater volatility and loss. Alternative strategies involve complex securities transactions that involve risks in addition to those risks with direct investments in securities described herein, including leverage risk and the risks described under “Derivatives Risk” and “Short Selling Risk”.

Value Investing Risk. A value stock may decrease in price or may not increase in price as anticipated by the Adviser if other investors fail to recognize the company’s value or the factors that the Adviser believes will cause the stock price to increase do not occur.

Smaller Cap Company Risk. Investments in securities of mid cap and small cap companies may be riskier, more volatile and more vulnerable to economic, market and industry changes than investments in larger, more established companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Foreign Securities and Emerging Market Risk. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. These risks are magnified in “emerging markets.” Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

Interest Rate and Credit Risk. The Fund’s investments in bonds, bank obligations, commercial paper and other debt securities will change in value based on changes in interest rates. If rates rise, the value of these investments generally drops. The Fund’s investments are subject to the risk that a counterparty will fail to make payments when due or default completely. If an issuer’s financial condition worsens, the credit quality of the issuer may deteriorate making it difficult for the Fund to sell such investments.

High Yield Securities Risk. The Fund may invest in debt securities that are considered to be speculative (commonly known as junk bonds). These securities are issued by companies which may be highly leveraged, less creditworthy or financially distressed. These securities are subject to greater risk of loss, greater sensitivity to interest rate and economic changes, valuation difficulties, and a potential lack of a secondary or public market for such securities. The market price of these securities can change suddenly and unexpectedly.

Government Securities Risk. The Fund may invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac) securities). Unlike Ginnie Mae securities, securities issued or guaranteed by U.S. government related organizations such as Fannie Mae and Freddie Mac are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government would provide financial support. Therefore, U.S. government related organizations such as Fannie Mae or Freddie Mac may not have the funds to meet their payment obligations in the future.

Sovereign Debt Risk. Sovereign debt securities are issued or guaranteed by foreign governmental entities. 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. There is no legal process for collecting sovereign debts 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.

Convertible Securities Risk. The value of convertible securities tends to decline as interest rates rise and, because of the conversion feature, tends to vary with fluctuations in the market value of the underlying securities. Convertible securities are usually subordinated to comparable nonconvertible securities. Convertible securities generally do not participate directly in any dividend increases or decreases of the underlying securities, although the market prices of convertible securities may be affected by any dividend changes or other changes in the underlying securities.

Commodity Risk. Exposure to commodities, commodity-related securities and commodity-linked derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity. Use of leveraged commodity-linked derivatives creates an opportunity for increased return but, at the same time, creates the possibility for greater loss (including the likelihood of greater volatility of the Fund’s net asset value), and there can be no assurance that the Fund’s use of leverage will be successful. In addition, to the extent that the Fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Subsidiary Risk. By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The derivatives and other investments held by the Subsidiary are generally similar to those commodity related investments that are permitted to be held by the Fund and are subject to the same risks that apply to such related commodity investments if held directly by the Fund. These risks are described elsewhere in this prospectus. There can be no assurance that the investment objective of the Subsidiary will be achieved. The Subsidiary is not registered under the Investment Company Act of 1940 (1940 Act), and is not subject to all the investor protections of the 1940 Act. 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 could adversely affect the Fund.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets, may be riskier than other types of investments and may increase the volatility of the Fund. To the extent that the Fund hedges its currency exposure into the U.S. dollar, it may reduce the effects of currency fluctuations. The Fund may also hedge from one foreign currency to another. In addition, the Fund’s use of currency hedging may not be successful and the use of such strategies may lower the Fund’s potential returns.

Investment Company and Pooled Investment Vehicle Risks. The Fund may invest in shares of other investment companies, exchange traded funds (ETFs) and other pooled investment vehicles, including those that invest in commodities. Shareholders bear both their proportionate share of the Fund’s expenses and similar expenses of the investment company or pooled investment vehicle. The price movement of an index-based ETF may not track the underlying index and may result in a loss. ETFs may trade at a price below their net asset value (also known as a discount). Certain pooled investment vehicles do not have the protections applicable to other types of investments under federal securities or commodities laws and may be subject to counterparty or credit risk. There may be no active market for shares of certain ETFs or pooled investment vehicles and such shares may be highly illiquid.

Real Estate Securities Risk. The Fund’s investments in real estate securities, including REITs, are subject to the same risks as direct investments in real estate and mortgages, and their value will depend on the value of the underlying real estate interests. These risks include default, prepayments, changes in value resulting from changes in interest rates and demand for real and rental property, and the management skill and creditworthiness of REIT issuers. The Fund will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the Fund.

Short Selling Risk. The Fund will incur a loss as a result of a short sale if the price of the security sold short increases in value between the date of entering into the short sale and the date on which the Fund purchases the security to replace the borrowed security or is required to pay under the swap agreement. Short sales are speculative transactions and involve special risks, including greater reliance on the Adviser’s ability to accurately anticipate the future value of a security. Furthermore, taking short positions in securities results in a form of leverage which may cause the Fund to be more volatile. The Fund’s loss on a short sale is potentially unlimited because there is no upward limit on the price the security subject to the short could attain. The Fund’s use of short sales in combination with long positions may not be successful and may result in greater losses or lower positive returns than if a Fund held only long positions.

The Securities and Exchange Commission (SEC) and financial industry regulatory authorities in other countries may impose prohibitions, restrictions or other regulatory requirements on short sales, which could inhibit the ability of the Adviser to enter into short sale transactions on behalf of the Fund.

Derivatives Risk. Derivatives, including swaps, options, futures, and forward contracts, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Investing in derivatives will result in a form of leverage. Leverage involves special risks. The Fund may be more volatile than if the Fund had not been leveraged because leverage tends to exaggerate the effect of any increase or decrease in the value of the Fund’s portfolio securities. The Fund cannot assure you that the use of leverage will result in a higher return on your investment, and using leverage could result in a net loss on your investment.

In addition to the risks associated with derivatives in general, the Fund will also be subject to risks related to swap agreements. The Fund may use swaps to establish both long and short positions in order to gain the desired exposure. Because swap agreements are not exchange-traded, but are private contracts into which the Fund and a swap counterparty enter as principals, the Fund may experience a loss or delay in recovering assets if the counterparty defaults on its obligations. The Fund will segregate or earmark liquid assets at its custodian bank in an amount sufficient to cover its obligations under swap agreements.

High Portfolio Turnover Risk. The Fund will likely engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

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 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 annual fund operating expenses, or in the Example, affect the Fund’s performance.

What are the Fund’s main investment strategies?

The Fund will seek to achieve its investment objective by allocating assets using a risk-parity approach. In determining portfolio construction, J.P.

The Fund will use derivative instruments in investing its assets, including swaps, options, futures and forward contracts. The Fund will also engage in short sales, including through swaps. As a result of the Fund’s use of derivatives and to serve as collateral, the Fund may hold significant amounts of U.S. Treasury obligations, including Treasury bills, bonds and notes and other obligations issued or guaranteed by the U.S. Treasury, other short-term investments, including money market funds and foreign currencies.

The Subsidiary is otherwise subject to the same fundamental, non-fundamental and certain other investment restrictions as the Fund.

There can be no assurance that employing a “diversified risk” approach will achieve any particular level of return or will, in fact, reduce volatility or potential loss.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. Equity securities are subject to “stock market risk” meaning that stock prices in general (or in particular, the prices of the types of securities in which a Fund invests) may decline over short or extended periods of time. When the value of the Fund’s securities goes down, the value of your investment in the Fund will be affected.

Model Risk. There can be no assurance that employing a “risk parity” approach to determine the weighting of return factors in the Fund’s portfolio will achieve any particular level of return, or will, in fact, reduce volatility or potential loss. In addition, given the complexity of the investment strategies, the Adviser will make use of quantitative models to, among other things, help determine the portfolio’s asset allocation weightings. To the extent the models used by the Adviser are incorrect or incomplete, the decisions made by the Adviser in reliance thereon will expose the Fund to potential risks.

Alternative Strategies Risk. The Fund will employ various alternative investment strategies that involve the use of complicated investment techniques. There is no guarantee that these strategies will succeed and their use may subject the Fund to greater volatility and loss. Alternative strategies involve complex securities transactions that involve risks in addition to those risks with direct investments in securities described herein, including leverage risk and the risks described under “Derivatives Risk” and “Short Selling Risk”.

Value Investing Risk. A value stock may decrease in price or may not increase in price as anticipated by the Adviser if other investors fail to recognize the company’s value or the factors that the Adviser believes will cause the stock price to increase do not occur.

Smaller Cap Company Risk. Investments in securities of mid cap and small cap companies may be riskier, more volatile and more vulnerable to economic, market and industry changes than investments in larger, more established companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Foreign Securities and Emerging Market Risk. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. These risks are magnified in “emerging markets.” Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

Interest Rate and Credit Risk. The Fund’s investments in bonds, bank obligations, commercial paper and other debt securities will change in value based on changes in interest rates. If rates rise, the value of these investments generally drops. The Fund’s investments are subject to the risk that a counterparty will fail to make payments when due or default completely. If an issuer’s financial condition worsens, the credit quality of the issuer may deteriorate making it difficult for the Fund to sell such investments.

High Yield Securities Risk. The Fund may invest in debt securities that are considered to be speculative (commonly known as junk bonds). These securities are issued by companies which may be highly leveraged, less creditworthy or financially distressed. These securities are subject to greater risk of loss, greater sensitivity to interest rate and economic changes, valuation difficulties, and a potential lack of a secondary or public market for such securities. The market price of these securities can change suddenly and unexpectedly.

Government Securities Risk. The Fund may invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac) securities). Unlike Ginnie Mae securities, securities issued or guaranteed by U.S. government related organizations such as Fannie Mae and Freddie Mac are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government would provide financial support. Therefore, U.S. government related organizations such as Fannie Mae or Freddie Mac may not have the funds to meet their payment obligations in the future.

Sovereign Debt Risk. Sovereign debt securities are issued or guaranteed by foreign governmental entities. 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. There is no legal process for collecting sovereign debts 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.

Convertible Securities Risk. The value of convertible securities tends to decline as interest rates rise and, because of the conversion feature, tends to vary with fluctuations in the market value of the underlying securities. Convertible securities are usually subordinated to comparable nonconvertible securities. Convertible securities generally do not participate directly in any dividend increases or decreases of the underlying securities, although the market prices of convertible securities may be affected by any dividend changes or other changes in the underlying securities.

Commodity Risk. Exposure to commodities, commodity-related securities and commodity-linked derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity. Use of leveraged commodity-linked derivatives creates an opportunity for increased return but, at the same time, creates the possibility for greater loss (including the likelihood of greater volatility of the Fund’s net asset value), and there can be no assurance that the Fund’s use of leverage will be successful. In addition, to the extent that the Fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Subsidiary Risk. By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The derivatives and other investments held by the Subsidiary are generally similar to those commodity related investments that are permitted to be held by the Fund and are subject to the same risks that apply to such related commodity investments if held directly by the Fund. These risks are described elsewhere in this prospectus. There can be no assurance that the investment objective of the Subsidiary will be achieved. The Subsidiary is not registered under the Investment Company Act of 1940 (1940 Act), and is not subject to all the investor protections of the 1940 Act. 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 could adversely affect the Fund.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets, may be riskier than other types of investments and may increase the volatility of the Fund. To the extent that the Fund hedges its currency exposure into the U.S. dollar, it may reduce the effects of currency fluctuations. The Fund may also hedge from one foreign currency to another. In addition, the Fund’s use of currency hedging may not be successful and the use of such strategies may lower the Fund’s potential returns.

Investment Company and Pooled Investment Vehicle Risks. The Fund may invest in shares of other investment companies, exchange traded funds (ETFs) and other pooled investment vehicles, including those that invest in commodities. Shareholders bear both their proportionate share of the Fund’s expenses and similar expenses of the investment company or pooled investment vehicle. The price movement of an index-based ETF may not track the underlying index and may result in a loss. ETFs may trade at a price below their net asset value (also known as a discount). Certain pooled investment vehicles do not have the protections applicable to other types of investments under federal securities or commodities laws and may be subject to counterparty or credit risk. There may be no active market for shares of certain ETFs or pooled investment vehicles and such shares may be highly illiquid.

Real Estate Securities Risk. The Fund’s investments in real estate securities, including REITs, are subject to the same risks as direct investments in real estate and mortgages, and their value will depend on the value of the underlying real estate interests. These risks include default, prepayments, changes in value resulting from changes in interest rates and demand for real and rental property, and the management skill and creditworthiness of REIT issuers. The Fund will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the Fund.

Short Selling Risk. The Fund will incur a loss as a result of a short sale if the price of the security sold short increases in value between the date of entering into the short sale and the date on which the Fund purchases the security to replace the borrowed security or is required to pay under the swap agreement. Short sales are speculative transactions and involve special risks, including greater reliance on the Adviser’s ability to accurately anticipate the future value of a security. Furthermore, taking short positions in securities results in a form of leverage which may cause the Fund to be more volatile. The Fund’s loss on a short sale is potentially unlimited because there is no upward limit on the price the security subject to the short could attain. The Fund’s use of short sales in combination with long positions may not be successful and may result in greater losses or lower positive returns than if a Fund held only long positions.

The Securities and Exchange Commission (SEC) and financial industry regulatory authorities in other countries may impose prohibitions, restrictions or other regulatory requirements on short sales, which could inhibit the ability of the Adviser to enter into short sale transactions on behalf of the Fund.

Derivatives Risk. Derivatives, including swaps, options, futures, and forward contracts, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Investing in derivatives will result in a form of leverage. Leverage involves special risks. The Fund may be more volatile than if the Fund had not been leveraged because leverage tends to exaggerate the effect of any increase or decrease in the value of the Fund’s portfolio securities. The Fund cannot assure you that the use of leverage will result in a higher return on your investment, and using leverage could result in a net loss on your investment.

In addition to the risks associated with derivatives in general, the Fund will also be subject to risks related to swap agreements. The Fund may use swaps to establish both long and short positions in order to gain the desired exposure. Because swap agreements are not exchange-traded, but are private contracts into which the Fund and a swap counterparty enter as principals, the Fund may experience a loss or delay in recovering assets if the counterparty defaults on its obligations. The Fund will segregate or earmark liquid assets at its custodian bank in an amount sufficient to cover its obligations under swap agreements.

High Portfolio Turnover Risk. The Fund will likely engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund will seek to achieve its investment objective by allocating assets using a risk-parity approach. In determining portfolio construction, J.P. Morgan Investment Management Inc., the Fund’s investment adviser (the Adviser), has identified a set of market-driven investment return sources that have a low correlation to each other and unique risk and return profiles (each a “return factor”). The Adviser believes that, in general, a portfolio’s market-driven returns are attributable to the individual contributions of various return factors. By employing a return factor-based approach, the Adviser believes it can identify the desired return factors and construct a portfolio to “diversify the risk” to which the Fund is exposed while also providing enhanced risk-adjusted returns relative to a conventional asset allocation strategy. The Adviser will seek to capture these market-driven investment contributions by using a proprietary investment model to allocate assets to alternative and traditional investment strategies in order to gain targeted investment exposure to each of these selected return factors.

In determining asset allocation, a traditional risk-parity approach seeks to balance the allocation of risk (as measured by volatility) across asset classes, so that higher risk asset classes (e.g., equities) have lower allocations than lower risk asset classes (e.g., debt securities) within the portfolio. In general, an investor’s potential return on an investment is tied to the risk of the investment. Higher risk investments generally provide the potential for higher gains (or losses) while lower risk investments generally provide the potential for lower losses (or gains). Risk-parity investing seeks to equalize a portfolio’s risk level between the higher risk asset classes and the lower risk asset classes in an effort to provide more consistent risk-adjusted return levels. The Fund will use a risk-parity approach but will focus on diversifying across return factors rather than asset classes. The return factors identified by the Adviser fall into the following broad categories: equity based return factors, fixed income based return factors, convertible bond based return factors, real estate based return factors, currency based return factors and commodity based return factors. The Adviser will seek to maintain an approximately, equally weighted exposure (as measured by volatility) to each of the individual return factors, so that each return factor contributes equally to the Fund’s overall volatility over the long term. The exposure to individual return factors, however, may vary over the shorter term based on the opportunity the Adviser sees in each individual return factor.

The Fund will invest its assets globally (including in emerging markets) in various instruments, including equity securities, debt securities (including below investment grade and unrated debt securities), convertible securities, real estate investment trusts (REITs), commodities and currencies. The Fund will use derivative instruments in investing its assets, including swaps, options, futures and forward contracts. The Fund will also engage in short sales, including through swaps. As a result of the Fund’s use of derivatives and to serve as collateral, the Fund may hold significant amounts of U.S. Treasury obligations, including Treasury bills, bonds and notes and other obligations issued or guaranteed by the U.S. Treasury, other short-term investments, including money market funds and foreign currencies. The Fund may also invest in exchange traded funds and other investment companies.

The amount that may be invested in any one instrument will vary and generally depend on the investment strategies employed by the Adviser at that time. However, there are no stated percentage limitations on the amount that can be invested in any one type of instrument and the Adviser may, at times, focus on a small number of instruments. Moreover, the Fund is generally unconstrained by any particular capitalization, style or sector and may invest in any region or country, including emerging markets.

The Fund will purchase a particular instrument when the Adviser believes that such instrument will allow the Fund to gain the desired exposure to a return factor. Conversely, the Fund will consider selling a particular instrument when it no longer provides the desired exposure to a return factor. In addition, investment decisions will take into account a return factor’s expected contribution to the Fund’s overall volatility.

The alternative investment strategies the Fund may use include equity market neutral, event driven, convertible arbitrage, relative value fixed income and currency, and relative value commodity, and the traditional investment strategies include long only investing in equity securities, fixed-income securities, REITs, commodities and currencies.

The Fund will gain exposure to commodity markets by investing up to 15% of its total assets in commodity related instruments either directly or indirectly through the JPM Diversified Risk Fund Ltd., a wholly owned subsidiary of the Fund organized under the laws of the Cayman Islands (the Subsidiary). The Subsidiary is also advised by the Adviser. The Subsidiary (unlike the Fund) may invest without limitation in commodity related investments, including commodity-linked swap agreements and other commodity-linked derivative instruments, such as those linked to the value of a particular commodity, commodity index or commodity futures contract, or a subset of commodities or commodity futures contracts. The Subsidiary is otherwise subject to the same fundamental, non-fundamental and certain other investment restrictions as the Fund.

There can be no assurance that employing a “diversified risk” approach will achieve any particular level of return or will, in fact, reduce volatility or potential loss.

Risk [Heading]

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. Equity securities are subject to “stock market risk” meaning that stock prices in general (or in particular, the prices of the types of securities in which a Fund invests) may decline over short or extended periods of time. When the value of the Fund’s securities goes down, the value of your investment in the Fund will be affected.

Model Risk. There can be no assurance that employing a “risk parity” approach to determine the weighting of return factors in the Fund’s portfolio will achieve any particular level of return, or will, in fact, reduce volatility or potential loss. In addition, given the complexity of the investment strategies, the Adviser will make use of quantitative models to, among other things, help determine the portfolio’s asset allocation weightings. To the extent the models used by the Adviser are incorrect or incomplete, the decisions made by the Adviser in reliance thereon will expose the Fund to potential risks.

Alternative Strategies Risk. The Fund will employ various alternative investment strategies that involve the use of complicated investment techniques. There is no guarantee that these strategies will succeed and their use may subject the Fund to greater volatility and loss. Alternative strategies involve complex securities transactions that involve risks in addition to those risks with direct investments in securities described herein, including leverage risk and the risks described under “Derivatives Risk” and “Short Selling Risk”.

Value Investing Risk. A value stock may decrease in price or may not increase in price as anticipated by the Adviser if other investors fail to recognize the company’s value or the factors that the Adviser believes will cause the stock price to increase do not occur.

Smaller Cap Company Risk. Investments in securities of mid cap and small cap companies may be riskier, more volatile and more vulnerable to economic, market and industry changes than investments in larger, more established companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Foreign Securities and Emerging Market Risk. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. These risks are magnified in “emerging markets.” Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

Interest Rate and Credit Risk. The Fund’s investments in bonds, bank obligations, commercial paper and other debt securities will change in value based on changes in interest rates. If rates rise, the value of these investments generally drops. The Fund’s investments are subject to the risk that a counterparty will fail to make payments when due or default completely. If an issuer’s financial condition worsens, the credit quality of the issuer may deteriorate making it difficult for the Fund to sell such investments.

High Yield Securities Risk. The Fund may invest in debt securities that are considered to be speculative (commonly known as junk bonds). These securities are issued by companies which may be highly leveraged, less creditworthy or financially distressed. These securities are subject to greater risk of loss, greater sensitivity to interest rate and economic changes, valuation difficulties, and a potential lack of a secondary or public market for such securities. The market price of these securities can change suddenly and unexpectedly.

Government Securities Risk. The Fund may invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac) securities). Unlike Ginnie Mae securities, securities issued or guaranteed by U.S. government related organizations such as Fannie Mae and Freddie Mac are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government would provide financial support. Therefore, U.S. government related organizations such as Fannie Mae or Freddie Mac may not have the funds to meet their payment obligations in the future.

Sovereign Debt Risk. Sovereign debt securities are issued or guaranteed by foreign governmental entities. 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. There is no legal process for collecting sovereign debts 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.

Convertible Securities Risk. The value of convertible securities tends to decline as interest rates rise and, because of the conversion feature, tends to vary with fluctuations in the market value of the underlying securities. Convertible securities are usually subordinated to comparable nonconvertible securities. Convertible securities generally do not participate directly in any dividend increases or decreases of the underlying securities, although the market prices of convertible securities may be affected by any dividend changes or other changes in the underlying securities.

Commodity Risk. Exposure to commodities, commodity-related securities and commodity-linked derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity. Use of leveraged commodity-linked derivatives creates an opportunity for increased return but, at the same time, creates the possibility for greater loss (including the likelihood of greater volatility of the Fund’s net asset value), and there can be no assurance that the Fund’s use of leverage will be successful. In addition, to the extent that the Fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Subsidiary Risk. By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The derivatives and other investments held by the Subsidiary are generally similar to those commodity related investments that are permitted to be held by the Fund and are subject to the same risks that apply to such related commodity investments if held directly by the Fund. These risks are described elsewhere in this prospectus. There can be no assurance that the investment objective of the Subsidiary will be achieved. The Subsidiary is not registered under the Investment Company Act of 1940 (1940 Act), and is not subject to all the investor protections of the 1940 Act. 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 could adversely affect the Fund.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets, may be riskier than other types of investments and may increase the volatility of the Fund. To the extent that the Fund hedges its currency exposure into the U.S. dollar, it may reduce the effects of currency fluctuations. The Fund may also hedge from one foreign currency to another. In addition, the Fund’s use of currency hedging may not be successful and the use of such strategies may lower the Fund’s potential returns.

Investment Company and Pooled Investment Vehicle Risks. The Fund may invest in shares of other investment companies, exchange traded funds (ETFs) and other pooled investment vehicles, including those that invest in commodities. Shareholders bear both their proportionate share of the Fund’s expenses and similar expenses of the investment company or pooled investment vehicle. The price movement of an index-based ETF may not track the underlying index and may result in a loss. ETFs may trade at a price below their net asset value (also known as a discount). Certain pooled investment vehicles do not have the protections applicable to other types of investments under federal securities or commodities laws and may be subject to counterparty or credit risk. There may be no active market for shares of certain ETFs or pooled investment vehicles and such shares may be highly illiquid.

Real Estate Securities Risk. The Fund’s investments in real estate securities, including REITs, are subject to the same risks as direct investments in real estate and mortgages, and their value will depend on the value of the underlying real estate interests. These risks include default, prepayments, changes in value resulting from changes in interest rates and demand for real and rental property, and the management skill and creditworthiness of REIT issuers. The Fund will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the Fund.

Short Selling Risk. The Fund will incur a loss as a result of a short sale if the price of the security sold short increases in value between the date of entering into the short sale and the date on which the Fund purchases the security to replace the borrowed security or is required to pay under the swap agreement. Short sales are speculative transactions and involve special risks, including greater reliance on the Adviser’s ability to accurately anticipate the future value of a security. Furthermore, taking short positions in securities results in a form of leverage which may cause the Fund to be more volatile. The Fund’s loss on a short sale is potentially unlimited because there is no upward limit on the price the security subject to the short could attain. The Fund’s use of short sales in combination with long positions may not be successful and may result in greater losses or lower positive returns than if a Fund held only long positions.

The Securities and Exchange Commission (SEC) and financial industry regulatory authorities in other countries may impose prohibitions, restrictions or other regulatory requirements on short sales, which could inhibit the ability of the Adviser to enter into short sale transactions on behalf of the Fund.

Derivatives Risk. Derivatives, including swaps, options, futures, and forward contracts, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Investing in derivatives will result in a form of leverage. Leverage involves special risks. The Fund may be more volatile than if the Fund had not been leveraged because leverage tends to exaggerate the effect of any increase or decrease in the value of the Fund’s portfolio securities. The Fund cannot assure you that the use of leverage will result in a higher return on your investment, and using leverage could result in a net loss on your investment.

In addition to the risks associated with derivatives in general, the Fund will also be subject to risks related to swap agreements. The Fund may use swaps to establish both long and short positions in order to gain the desired exposure. Because swap agreements are not exchange-traded, but are private contracts into which the Fund and a swap counterparty enter as principals, the Fund may experience a loss or delay in recovering assets if the counterparty defaults on its obligations. The Fund will segregate or earmark liquid assets at its custodian bank in an amount sufficient to cover its obligations under swap agreements.

High Portfolio Turnover Risk. The Fund will likely engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund will seek to achieve its investment objective by allocating assets using a risk-parity approach. In determining portfolio construction, J.P. Morgan Investment Management Inc., the Fund’s investment adviser (the Adviser), has identified a set of market-driven investment return sources that have a low correlation to each other and unique risk and return profiles (each a “return factor”). The Adviser believes that, in general, a portfolio’s market-driven returns are attributable to the individual contributions of various return factors. By employing a return factor-based approach, the Adviser believes it can identify the desired return factors and construct a portfolio to “diversify the risk” to which the Fund is exposed while also providing enhanced risk-adjusted returns relative to a conventional asset allocation strategy. The Adviser will seek to capture these market-driven investment contributions by using a proprietary investment model to allocate assets to alternative and traditional investment strategies in order to gain targeted investment exposure to each of these selected return factors.

In determining asset allocation, a traditional risk-parity approach seeks to balance the allocation of risk (as measured by volatility) across asset classes, so that higher risk asset classes (e.g., equities) have lower allocations than lower risk asset classes (e.g., debt securities) within the portfolio. In general, an investor’s potential return on an investment is tied to the risk of the investment. Higher risk investments generally provide the potential for higher gains (or losses) while lower risk investments generally provide the potential for lower losses (or gains). Risk-parity investing seeks to equalize a portfolio’s risk level between the higher risk asset classes and the lower risk asset classes in an effort to provide more consistent risk-adjusted return levels. The Fund will use a risk-parity approach but will focus on diversifying across return factors rather than asset classes. The return factors identified by the Adviser fall into the following broad categories: equity based return factors, fixed income based return factors, convertible bond based return factors, real estate based return factors, currency based return factors and commodity based return factors. The Adviser will seek to maintain an approximately, equally weighted exposure (as measured by volatility) to each of the individual return factors, so that each return factor contributes equally to the Fund’s overall volatility over the long term. The exposure to individual return factors, however, may vary over the shorter term based on the opportunity the Adviser sees in each individual return factor.

The Fund will invest its assets globally (including in emerging markets) in various instruments, including equity securities, debt securities (including below investment grade and unrated debt securities), convertible securities, real estate investment trusts (REITs), commodities and currencies. The Fund will use derivatives instruments in investing its assets, including swaps, options, futures and forward contracts. The Fund will also engage in short sales, including through swaps. As a result of the Fund’s use of derivatives and to serve as collateral, the Fund may hold significant amounts of U.S. Treasury obligations, including Treasury bills, bonds and notes and other obligations issued or guaranteed by the U.S. Treasury, other short-term investments, including money market funds and foreign currencies. The Fund may also invest in exchange traded funds and other investment companies.

The amount that may be invested in any one instrument will vary and generally depend on the investment strategies employed by the Adviser at that time. However, there are no stated percentage limitations on the amount that can be invested in any one type of instrument and the Adviser may, at times, focus on a small number of instruments. Moreover, the Fund is generally unconstrained by any particular capitalization, style or sector and may invest in any region or country, including emerging markets.

The Fund will purchase a particular instrument when the Adviser believes that such instrument will allow the Fund to gain the desired exposure to a return factor. Conversely, the Fund will consider selling a particular instrument when it no longer provides the desired exposure to a return factor. In addition, investment decisions will take into account a return factor’s expected contribution to the Fund’s overall volatility.

The alternative investment strategies the Fund may use include equity market neutral, event driven, convertible arbitrage, relative value fixed income and currency and relative value commodity, and the traditional investment strategies include long only investing in equity securities, fixed-income securities, REITs, commodities and currencies.

The Fund will gain exposure to commodity markets by investing up to 15% of its total assets in commodity related instruments either directly or indirectly through the JPM Diversified Risk Fund Ltd., a wholly owned subsidiary of the Fund organized under the laws of the Cayman Islands (the Subsidiary). The Subsidiary is also advised by the Adviser. The Subsidiary (unlike the Fund) may invest without limitation in commodity related investments, including commodity-linked swap agreements and other commodity-linked derivative instruments, such as those linked to the value of a particular commodity, commodity index or commodity futures contract, or a subset of commodities or commodity futures contracts. The Subsidiary is otherwise subject to the same fundamental, non-fundamental and certain other investment restrictions as the Fund.

There can be no assurance that employing a “diversified risk” approach will achieve any particular level of return or will, in fact, reduce volatility or potential loss.

Risk [Heading]

rr_RiskHeading

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the Adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. Equity securities are subject to “stock market risk” meaning that stock prices in general (or in particular, the prices of the types of securities in which a Fund invests) may decline over short or extended periods of time. When the value of the Fund’s securities goes down, the value of your investment in the Fund will be affected.

Model Risk. There can be no assurance that employing a “risk parity” approach to determine the weighting of return factors in the Fund’s portfolio will achieve any particular level of return, or will, in fact, reduce volatility or potential loss. In addition, given the complexity of the investment strategies, the Adviser will make use of quantitative models to, among other things, help determine the portfolio’s asset allocation weightings. To the extent the models used by the Adviser are incorrect or incomplete, the decisions made by the Adviser in reliance thereon will expose the Fund to potential risks.

Alternative Strategies Risk. The Fund will employ various alternative investment strategies that involve the use of complicated investment techniques. There is no guarantee that these strategies will succeed and their use may subject the Fund to greater volatility and loss. Alternative strategies involve complex securities transactions that involve risks in addition to those risks with direct investments in securities described herein, including leverage risk and the risks described under “Derivatives Risk” and “Short Selling Risk”.

Value Investing Risk. A value stock may decrease in price or may not increase in price as anticipated by the Adviser if other investors fail to recognize the company’s value or the factors that the Adviser believes will cause the stock price to increase do not occur.

Smaller Cap Company Risk. Investments in securities of mid cap and small cap companies may be riskier, more volatile and more vulnerable to economic, market and industry changes than investments in larger, more established companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Foreign Securities and Emerging Market Risk. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. These risks are magnified in “emerging markets.” Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

Interest Rate and Credit Risk. The Fund’s investments in bonds, bank obligations, commercial paper and other debt securities will change in value based on changes in interest rates. If rates rise, the value of these investments generally drops. The Fund’s investments are subject to the risk that a counterparty will fail to make payments when due or default completely. If an issuer’s financial condition worsens, the credit quality of the issuer may deteriorate making it difficult for the Fund to sell such investments.

High Yield Securities Risk. The Fund may invest in debt securities that are considered to be speculative (commonly known as junk bonds). These securities are issued by companies which may be highly leveraged, less creditworthy or financially distressed. These securities are subject to greater risk of loss, greater sensitivity to interest rate and economic changes, valuation difficulties, and a potential lack of a secondary or public market for such securities. The market price of these securities can change suddenly and unexpectedly.

Government Securities Risk. The Fund may invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac) securities). Unlike Ginnie Mae securities, securities issued or guaranteed by U.S. government related organizations such as Fannie Mae and Freddie Mac are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government would provide financial support. Therefore, U.S. government related organizations such as Fannie Mae or Freddie Mac may not have the funds to meet their payment obligations in the future.

Sovereign Debt Risk. Sovereign debt securities are issued or guaranteed by foreign governmental entities. 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. There is no legal process for collecting sovereign debts 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.

Convertible Securities Risk. The value of convertible securities tends to decline as interest rates rise and, because of the conversion feature, tends to vary with fluctuations in the market value of the underlying securities. Convertible securities are usually subordinated to comparable nonconvertible securities. Convertible securities generally do not participate directly in any dividend increases or decreases of the underlying securities, although the market prices of convertible securities may be affected by any dividend changes or other changes in the underlying securities.

Commodity Risk. Exposure to commodities, commodity-related securities and commodity-linked derivatives may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity. Use of leveraged commodity-linked derivatives creates an opportunity for increased return but, at the same time, creates the possibility for greater loss (including the likelihood of greater volatility of the Fund’s net asset value), and there can be no assurance that the Fund’s use of leverage will be successful. In addition, to the extent that the Fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Subsidiary Risk. By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The derivatives and other investments held by the Subsidiary are generally similar to those commodity related investments that are permitted to be held by the Fund and are subject to the same risks that apply to such related commodity investments if held directly by the Fund. These risks are described elsewhere in this prospectus. There can be no assurance that the investment objective of the Subsidiary will be achieved. The Subsidiary is not registered under the Investment Company Act of 1940 (1940 Act), and is not subject to all the investor protections of the 1940 Act. 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 could adversely affect the Fund.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets, may be riskier than other types of investments and may increase the volatility of the Fund. To the extent that the Fund hedges its currency exposure into the U.S. dollar, it may reduce the effects of currency fluctuations. The Fund may also hedge from one foreign currency to another. In addition, the Fund’s use of currency hedging may not be successful and the use of such strategies may lower the Fund’s potential returns.

Investment Company and Pooled Investment Vehicle Risks. The Fund may invest in shares of other investment companies, exchange traded funds (ETFs) and other pooled investment vehicles, including those that invest in commodities. Shareholders bear both their proportionate share of the Fund’s expenses and similar expenses of the investment company or pooled investment vehicle. The price movement of an index-based ETF may not track the underlying index and may result in a loss. ETFs may trade at a price below their net asset value (also known as a discount). Certain pooled investment vehicles do not have the protections applicable to other types of investments under federal securities or commodities laws and may be subject to counterparty or credit risk. There may be no active market for shares of certain ETFs or pooled investment vehicles and such shares may be highly illiquid.

Real Estate Securities Risk. The Fund’s investments in real estate securities, including REITs, are subject to the same risks as direct investments in real estate and mortgages, and their value will depend on the value of the underlying real estate interests. These risks include default, prepayments, changes in value resulting from changes in interest rates and demand for real and rental property, and the management skill and creditworthiness of REIT issuers. The Fund will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the Fund.

Short Selling Risk. The Fund will incur a loss as a result of a short sale if the price of the security sold short increases in value between the date of entering into the short sale and the date on which the Fund purchases the security to replace the borrowed security or is required to pay under the swap agreement. Short sales are speculative transactions and involve special risks, including greater reliance on the Adviser’s ability to accurately anticipate the future value of a security. Furthermore, taking short positions in securities results in a form of leverage which may cause the Fund to be more volatile. The Fund’s loss on a short sale is potentially unlimited because there is no upward limit on the price the security subject to the short could attain. The Fund’s use of short sales in combination with long positions may not be successful and may result in greater losses or lower positive returns than if a Fund held only long positions.

The Securities and Exchange Commission (SEC) and financial industry regulatory authorities in other countries may impose prohibitions, restrictions or other regulatory requirements on short sales, which could inhibit the ability of the Adviser to enter into short sale transactions on behalf of the Fund.

Derivatives Risk. Derivatives, including swaps, options, futures, and forward contracts, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Investing in derivatives will result in a form of leverage. Leverage involves special risks. The Fund may be more volatile than if the Fund had not been leveraged because leverage tends to exaggerate the effect of any increase or decrease in the value of the Fund’s portfolio securities. The Fund cannot assure you that the use of leverage will result in a higher return on your investment, and using leverage could result in a net loss on your investment.

In addition to the risks associated with derivatives in general, the Fund will also be subject to risks related to swap agreements. The Fund may use swaps to establish both long and short positions in order to gain the desired exposure. Because swap agreements are not exchange-traded, but are private contracts into which the Fund and a swap counterparty enter as principals, the Fund may experience a loss or delay in recovering assets if the counterparty defaults on its obligations. The Fund will segregate or earmark liquid assets at its custodian bank in an amount sufficient to cover its obligations under swap agreements.

High Portfolio Turnover Risk. The Fund will likely engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.
