above, as supplemented

At a meeting held on August 16-17, 2016, the Board of Trustees of JPMorgan Trust I, with regard to the JPMorgan Tax Aware Equity Fund and the JPMorgan Tax Aware Real Return Fund (each, an “Affected Fund”, and collectively, the “Affected Funds”), approved: (1) the conversion of Select Class Shares of each of the Affected Funds into Institutional Class Shares of the same Fund, (2) the increase in the Shareholder Service Fee of the Institutional Class Shares of the Affected Funds from 0.10% to 0.25% of its average daily net assets, (3) the reduction of the investment minimum for the Institutional Class Shares of the Affected Funds and (4) the renaming of the Institutional Class Shares of each Affected Fund to the Class I Shares on April 3, 2017. These changes were recommended by the Funds’ adviser, J.P. Morgan Investment Management Inc. (“JPMIM”).

As a result of the changes approved by the Board of Trustees, the following changes will be made:

Select Class: Share Class Conversion

Effective April 3, 2017, Select Class Shares of the Affected Funds will no longer be available for purchase.

After the close of business on March 31, 2017, the Affected Funds will automatically convert their Select Class Shares into Institutional Class Shares. Prior to the conversion, shareholders of Select Class Shares may redeem their investments as described in the Fund’s Prospectus. Depending on the tax-status of the shareholder and whether or not the account is invested through a tax-deferred arrangement such as a 401(k) plan account, such redemption may be a taxable event resulting in taxable income to the shareholder. Please consult your tax advisor on this issue. The conversion will not be considered a taxable event for federal income tax purposes.

You can obtain additional information about the Institutional Class Shares of an Affected Fund by reviewing the Affected Fund’s prospectus. You can obtain a copy of your Affected Fund’s prospectus by visiting www.jpmorganfunds.com/funddocuments or by calling 1-800-480-4111.

If shares are not redeemed prior to the conversion, following the conversion, each shareholder owning Select Class Shares of an Affected Fund will own a number of Institutional Class Shares of the same Fund equal to the aggregate value of the shareholder’s Select Class Shares at the time of automatic conversion.

Share Class Name Change

Effective April 3, 2017, the Institutional Class Shares of the Affected Funds will change their name to Class I Shares.

Investment Minimum Reduction

Effective April 3, 2017, the investment minimum for Class I (the former Institutional Class Shares) Shares of the Affected Funds will be decreased from a minimum initial investment of $3,000,000 to a minimum initial investment of $1,000,000. Beginning on April 3, 2017, employees of JPMorgan Chase and its affiliates and officers or trustees of the Affected Funds will be permitted to invest in the Class I Shares of the Affected Funds with a minimum initial investment of $1,000. In addition, employees of JPMorgan Chase and its affiliates and officers or trustees of the Funds investing in Class I Shares of the Affected Funds will be permitted to establish Systematic Purchase and Redemptions Plans. If establishing a Systematic Purchase Plan, the minimum for subsequent investments will be $50.

Shareholder Service Fee Increase

Effective April 3, 2017, the Shareholder Service Fee for the Class I Shares of each Affected Fund will be increased from 0.10% to 0.25% of its average daily net assets. Additionally, the contractual expense waivers in effect on April 3, 2017 for each of the Affected Funds will remain in effect through October 31, 2018, at which time the adviser and/or its affiliates will determine whether to renew or revise them.

The conversion will not be considered a taxable event for federal income tax purposes.

You can obtain additional information about the Institutional Class Shares of an Affected Fund by reviewing the Affected Fund’s prospectus. You can obtain a copy of your Affected Fund’s prospectus by visiting www.jpmorganfunds.com/funddocuments or by calling 1-800-480-4111.

If shares are not redeemed prior to the conversion, following the conversion, each shareholder owning Select Class Shares of an Affected Fund will own a number of Institutional Class Shares of the same Fund equal to the aggregate value of the shareholder’s Select Class Shares at the time of automatic conversion.

Share Class Name Change

Effective April 3, 2017, the Institutional Class Shares of the Affected Funds will change their name to Class I Shares.

Investment Minimum Reduction

Effective April 3, 2017, the investment minimum for Class I (the former Institutional Class Shares) Shares of the Affected Funds will be decreased from a minimum initial investment of $3,000,000 to a minimum initial investment of $1,000,000. Beginning on April 3, 2017, employees of JPMorgan Chase and its affiliates and officers or trustees of the Affected Funds will be permitted to invest in the Class I Shares of the Affected Funds with a minimum initial investment of $1,000. In addition, employees of JPMorgan Chase and its affiliates and officers or trustees of the Funds investing in Class I Shares of the Affected Funds will be permitted to establish Systematic Purchase and Redemptions Plans. If establishing a Systematic Purchase Plan, the minimum for subsequent investments will be $50.

Shareholder Service Fee Increase

Effective April 3, 2017, the Shareholder Service Fee for the Class I Shares of each Affected Fund will be increased from 0.10% to 0.25% of its average daily net assets. Additionally, the contractual expense waivers in effect on April 3, 2017 for each of the Affected Funds will remain in effect through October 31, 2018, at which time the adviser and/or its affiliates will determine whether to renew or revise them.

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. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 64% of the average value of its portfolio.

What are the Fund’s main investment strategies?

The Fund has significant flexibility to invest in a broad range of equity, fixed income and alternative asset classes in the U.S. and other markets throughout the world, both developed and emerging. J.P. Morgan Investment Management Inc. (JPMIM or adviser) uses a flexible asset allocation approach in constructing the Fund's portfolio. Under normal circumstances, the Fund will invest at least 40% of its total assets in countries other than the United States (Non-U.S. Countries) unless the adviser determines, in its sole discretion, that conditions are not favorable. If the adviser determines that conditions are not favorable, the Fund may invest under 40% of its total assets in Non-U.S. Countries provided that the Fund will not invest less than 30% of its total assets in Non-U.S. Countries under normal circumstances except for temporary defensive purposes. In managing the Fund, the adviser will invest in issuers in at least three countries other than the U.S. under normal circumstances. The Fund will invest across the full range of asset classes. Ranges for broad asset classes are:

Global Equity	10-90	%
Global Fixed Income	10-90	%
Alternatives	0-60	%
Cash and Cash Equivalents	0-80	%

The Fund's equity investments may include common stock, preferred stock, exchange traded funds (ETFs), convertible securities, depositary receipts, warrants to buy common stocks, master limited partnerships (MLPs), and J.P. Morgan Funds. The Fund is generally unconstrained by any particular capitalization with regard to its equity investments.

The Fund's fixed income investments may include bank obligations, convertible securities, U.S. government securities (including agencies and instrumentalities), mortgage-backed and mortgage-related securities (which may include securities that are issued by non-governmental entities), domestic and foreign corporate bonds, high yield securities (junk bonds), loan assignments and participations (Loans), debt obligations issued or guaranteed by a foreign sovereign government or its agencies, authorities or political subdivisions, floating rate securities, inflation-indexed bonds, inflation-linked securities such as Treasury Inflation Protected Securities (TIPS), J.P. Morgan Funds, and ETFs. The Fund is generally unconstrained with regard to the duration of its fixed income investments.

The Fund's alternative investments include securities that are not a part of the Fund's global equity or global fixed income investments. These investments may include individual securities (such as convertible securities, inflation-sensitive securities and preferred stock), J.P. Morgan Funds, ETFs, exchange traded notes (ETNs) and exchange traded commodities (ETCs). The investments in this asset class may give the Fund exposure to: market neutral strategies, long/short strategies, real estate (including real estate investment trusts (REITS)), currencies and commodities.

The Fund may invest in ETFs in order to gain exposure to particular asset classes. The Fund expects that, to the extent it invests in ETFs, it will primarily invest in passively managed ETFs. A passively managed ETF is a registered investment company that seeks to track the performance of a particular market index or security. These indexes include not only broad-based market indexes but more specific indexes as well, including those relating to particular sectors, markets, regions, industries or factors.

In addition to direct investments in securities, derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may also be used as substitutes for securities in which the Fund can invest. For example, in implementing equity market neutral strategies and macro based strategies, the Fund may use a total return swap to establish both long and short positions in order to gain the desired exposure rather than physically purchasing and selling short each instrument. The Fund may use futures contracts, options, forwards, and swaps to more effectively gain targeted equity and fixed income exposure from its cash positions, to hedge investments, for risk management and to attempt to increase the Fund's gain. The Fund may use futures contracts, forward contracts, options (including options on interest rate futures contracts and interest rate swaps), swaps, and credit default swaps to help manage duration, sector and yield curve exposure and credit and spread volatility. The Fund may utilize exchange traded futures contracts for cash management and to gain exposure to equities pending investment in individual securities. To the extent that the Fund does not utilize underlying funds to gain exposure to commodities, it may utilize commodity linked derivatives or commodity swaps to gain exposure to commodities.

The Fund may invest in securities denominated in any currency. The Fund may utilize forward currency transactions to hedge exposure to non-dollar investments back to the U.S. dollar.

As part of the underlying strategies, the Fund may enter into short sales. In short selling transactions, the Fund sells a security it does not own in anticipation of a decline in the market value of the security. To complete the transaction, the Fund must borrow the security to make delivery to the buyer. The Fund is obligated to replace the security borrowed by purchasing it subsequently at the market price at the time of replacement.

The Fund will likely engage in active and frequent trading.

Investment Process: As attractive investments across asset classes and strategies arise, the adviser attempts to capture these opportunities and has wide latitude to allocate the Fund's assets among strategies and asset classes. The adviser establishes the strategic and tactical allocation for the Fund and makes decisions concerning strategies, sectors, and overall portfolio construction. The adviser develops its investment insights through the combination of top-down macro views, together with the bottom-up views of the separate asset class specialists within J.P. Morgan Asset Management globally.

In buying and selling investments for the Fund, the adviser employs a continuous four-step process: (1) making asset allocation decisions based on JPMIM's assessment of the intermediate term (6–18 months) market outlook; (2) constructing the portfolio after considering the Fund's risk and return target, by determining the weightings of the asset classes, selecting the underlying securities, funds and other instruments; (3) analyzing the investment capabilities of the underlying portfolio managers and funds, and (4) monitoring portfolio exposures and weightings and rebalancing portfolio exposures and weightings in response to market price action and changes in JPMIM's shorter term market outlook.

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 instruments 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund's performance and ability to meet its investment objective.

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. When the value of the Fund's securities goes down, your investment in the Fund decreases in value.

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. Securities in the Fund's portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Interest Rate and Credit Risk. The Fund's investments in bonds and other debt securities will change in value based on changes in interest rates. If rates rise, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate Loans and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given the historically low interest rate environment, risks associated with rising rates are heightened. The Fund's investments are subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund's investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund's securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer's securities.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares' values may fluctuate in response to events affecting that industry or sector.

Foreign Securities, Emerging Markets, and Currency Risk. The Fund may invest all of its assets in securities denominated in foreign currencies. Investments in foreign currencies, 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, sanctions or other measures by the United States or other governments, 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 or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. 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. These risks are magnified in countries in "emerging markets." Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers. While the Fund may engage in various strategies to hedge against currency risk, it is not required to do so.

Derivatives Risk. Derivatives, including futures contracts, options, forwards, swaps, and commodity linked derivatives, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund's original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including the credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate 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.

High Yield Securities and Loan Risk. The Fund invests in instruments including junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid. No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. The inability to dispose of the Fund's securities and other investments in a timely fashion could result in losses to the Fund. Because some instruments may have a more limited secondary market, liquidity risk is more pronounced for the Fund than for funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, the Fund may have to reinvest in instruments with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these instruments, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Mortgage-Related and Other Mortgage-Backed Securities Risk. The Fund may invest in both residential or commercial mortgage-related and mortgage-backed securities that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. In periods of rising interest rates, the Fund may be subject to extension risk, and may receive principal later than expected. As a result, in periods of rising interest rates, the Fund may exhibit additional volatility. During periods of difficult or frozen credit markets, significant changes in interest rates or deteriorating economic conditions, such securities may decline in value, face valuation difficulties, become more volatile and/or become 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 credit-worthiness 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.

MLP Risk. MLPs may trade infrequently and in limited volume and they may be subject to more abrupt or erratic price movements than securities of larger or more broadly-based companies. MLPs are subject to "commodity risks" as well as the risks associated with the specific industry or industries in which the partnership invests. In addition, the managing general partner of an MLP may receive an incentive allocation based on increases in the amount and growth of cash distributions to investors in the MLP. This method of compensation may create an incentive for the managing general partner to make investments that are riskier or more speculative than would be the case in the absence of such compensation arrangements. Certain MLPs may operate in, or have exposure to, the energy sector. The energy sector can be significantly affected by changes in the prices and supplies of oil and other energy fuels, energy conservation, the success of exploration projects, and tax and other government regulations, policies of the Organization of Petroleum Exporting Countries (OPEC) and relationships among OPEC members and between OPEC and oil importing nations.

Investment Company and Pooled Investment Vehicle Risk. The Fund may invest in shares of other investment companies, including closed-end funds, ETFs and other pooled investment vehicles, including those holding commodities, currencies or commodity futures. Shareholders bear both their proportionate share of the Fund's expenses and similar expenses of the investment company or pooled investment vehicle. ETFs and other investment companies or pooled investment vehicles that invest in commodities or currencies are subject to the risks associated with direct investments in commodities or currencies. The price and movement of an ETF, closed-end fund or pooled investment vehicle designed to track an index may not track the index and may result in a loss. In addition, closed-end funds that trade on an exchange often trade at a price below their net asset value (also known as a discount). Certain ETFs, closed-end funds or pooled investment vehicles traded on exchanges may be thinly traded and experience large spreads between the "ask" price quoted by a seller and the "bid" price offered by a buyer. There may be no active market for shares of certain closed-end funds or pooled investment vehicles (especially those not traded on exchanges) and such shares may be highly illiquid. 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.

Government Securities Risk. The Fund invests in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. 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 may not have the funds to meet their payment obligations in the future.

Inflation-Linked Securities Risk. Unlike conventional bonds, the principal or interest of inflation-linked securities such as TIPS is adjusted periodically to a specified rate of inflation (e.g., Consumer Price Index for all Urban Consumers (CPI-U)). There can be no assurance that the inflation index used will accurately measure the real rate of inflation. These securities may lose value in the event that the actual rate of inflation is different than the rate of the inflation index.

ETN Risk. Generally, ETNs are structured as senior, unsecured notes in which an issuer such as a bank agrees to pay a return based on the target commodity index less any fees. ETNs are synthetic instruments that allow individual investors to have access to derivatives linked to commodities and assets such as oil, Currencies and foreign stock indexes. ETNs combine certain aspects of bond and ETFs. Similar to ETFs, ETNs are traded on a major exchange (e.g., the New York Stock Exchange) during normal trading hours. However, investors can also hold the ETN until maturity. At maturity, the issuer pays to the investor a cash amount equal to the principal amount, subject to the day's index factor. ETN returns are based upon the performance of a market index minus applicable fees. The value of an ETN may be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying commodities markets, changes in the applicable interest rates, changes in the issuer's credit rating and economic, legal, political or geographic events that affect the referenced commodity.

The value of the ETN may drop due to a downgrade in the issuer's credit rating, even if the underlying index remains unchanged. Investments in ETNs are subject to the risks facing income securities in general including the risk that a counterparty will fail to make payments when due or default. In addition, investors in ETNs generally have no right with respect to the instruments underlying the index or any right to receive delivery of the instruments underlying the index.

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 the short sale and the date on which the fund purchases the security to replace the borrowed security. In addition, a lender may request, or market conditions may dictate, that securities sold short be returned to the lender on short notice, and the Fund may have to buy the securities sold short at an unfavorable price. If this occurs, any anticipated gain to the Fund may be reduced or eliminated or the short sale may result in a loss. The Fund's losses are potentially unlimited in a short sale transaction. 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.

Commodity Risk. Exposure to commodities, commodity-related securities and 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.

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.

High Portfolio Turnover Risk. The Fund may 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.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund's performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

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.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Select Class Shares has varied from year to year for the past five calendar years. The table shows the average annual total returns for the past one year, five years and life of the Fund. The table compares that performance to the MSCI World Index (net of foreign withholding taxes), the Bloomberg Barclays Global Aggregate Index — Unhedged USD (new benchmark), the Bloomberg Barclays U.S. Aggregate Index (old benchmark), the Global Allocation Composite Benchmark, comprised of 60% MSCI World Index (net of foreign withholding taxes) and 40% Bloomberg Barclays Global Aggregate Index — Unhedged USD, and the Lipper Flexible Portfolio Funds Index. The Lipper index is based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other indexes, the Lipper index includes the fees and expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will performance in the future.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund has significant flexibility to invest in a broad range of equity, fixed income and alternative asset classes in the U.S. and other markets throughout the world, both developed and emerging. J.P. Morgan Investment Management Inc. (JPMIM or adviser) uses a flexible asset allocation approach in constructing the Fund's portfolio. Under normal circumstances, the Fund will invest at least 40% of its total assets in countries other than the United States (Non-U.S. Countries) unless the adviser determines, in its sole discretion, that conditions are not favorable. If the adviser determines that conditions are not favorable, the Fund may invest under 40% of its total assets in Non-U.S. Countries provided that the Fund will not invest less than 30% of its total assets in Non-U.S. Countries under normal circumstances except for temporary defensive purposes. In managing the Fund, the adviser will invest in issuers in at least three countries other than the U.S. under normal circumstances. The Fund will invest across the full range of asset classes. Ranges for broad asset classes are:

Global Equity	10-90	%
Global Fixed Income	10-90	%
Alternatives	0-60	%
Cash and Cash Equivalents	0-80	%

The Fund's equity investments may include common stock, preferred stock, exchange traded funds (ETFs), convertible securities, depositary receipts, warrants to buy common stocks, master limited partnerships (MLPs), and J.P. Morgan Funds. The Fund is generally unconstrained by any particular capitalization with regard to its equity investments.

The Fund's fixed income investments may include bank obligations, convertible securities, U.S. government securities (including agencies and instrumentalities), mortgage-backed and mortgage-related securities (which may include securities that are issued by non-governmental entities), domestic and foreign corporate bonds, high yield securities (junk bonds), loan assignments and participations (Loans), debt obligations issued or guaranteed by a foreign sovereign government or its agencies, authorities or political subdivisions, floating rate securities, inflation-indexed bonds, inflation-linked securities such as Treasury Inflation Protected Securities (TIPS), J.P. Morgan Funds, and ETFs. The Fund is generally unconstrained with regard to the duration of its fixed income investments.

The Fund's alternative investments include securities that are not a part of the Fund's global equity or global fixed income investments. These investments may include individual securities (such as convertible securities, inflation-sensitive securities and preferred stock), J.P. Morgan Funds, ETFs, exchange traded notes (ETNs) and exchange traded commodities (ETCs). The investments in this asset class may give the Fund exposure to: market neutral strategies, long/short strategies, real estate (including real estate investment trusts (REITS)), currencies and commodities.

The Fund may invest in ETFs in order to gain exposure to particular asset classes. The Fund expects that, to the extent it invests in ETFs, it will primarily invest in passively managed ETFs. A passively managed ETF is a registered investment company that seeks to track the performance of a particular market index or security. These indexes include not only broad-based market indexes but more specific indexes as well, including those relating to particular sectors, markets, regions, industries or factors.

In addition to direct investments in securities, derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may also be used as substitutes for securities in which the Fund can invest. For example, in implementing equity market neutral strategies and macro based strategies, the Fund may use a total return swap to establish both long and short positions in order to gain the desired exposure rather than physically purchasing and selling short each instrument. The Fund may use futures contracts, options, forwards, and swaps to more effectively gain targeted equity and fixed income exposure from its cash positions, to hedge investments, for risk management and to attempt to increase the Fund's gain. The Fund may use futures contracts, forward contracts, options (including options on interest rate futures contracts and interest rate swaps), swaps, and credit default swaps to help manage duration, sector and yield curve exposure and credit and spread volatility. The Fund may utilize exchange traded futures contracts for cash management and to gain exposure to equities pending investment in individual securities. To the extent that the Fund does not utilize underlying funds to gain exposure to commodities, it may utilize commodity linked derivatives or commodity swaps to gain exposure to commodities.

The Fund may invest in securities denominated in any currency. The Fund may utilize forward currency transactions to hedge exposure to non-dollar investments back to the U.S. dollar.

As part of the underlying strategies, the Fund may enter into short sales. In short selling transactions, the Fund sells a security it does not own in anticipation of a decline in the market value of the security. To complete the transaction, the Fund must borrow the security to make delivery to the buyer. The Fund is obligated to replace the security borrowed by purchasing it subsequently at the market price at the time of replacement.

The Fund will likely engage in active and frequent trading.

Investment Process: As attractive investments across asset classes and strategies arise, the adviser attempts to capture these opportunities and has wide latitude to allocate the Fund's assets among strategies and asset classes. The adviser establishes the strategic and tactical allocation for the Fund and makes decisions concerning strategies, sectors, and overall portfolio construction. The adviser develops its investment insights through the combination of top-down macro views, together with the bottom-up views of the separate asset class specialists within J.P. Morgan Asset Management globally.

In buying and selling investments for the Fund, the adviser employs a continuous four-step process: (1) making asset allocation decisions based on JPMIM's assessment of the intermediate term (6–18 months) market outlook; (2) constructing the portfolio after considering the Fund's risk and return target, by determining the weightings of the asset classes, selecting the underlying securities, funds and other instruments; (3) analyzing the investment capabilities of the underlying portfolio managers and funds, and (4) monitoring portfolio exposures and weightings and rebalancing portfolio exposures and weightings in response to market price action and changes in JPMIM's shorter term market outlook.

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 instruments 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund's performance and ability to meet its investment objective.

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. When the value of the Fund's securities goes down, your investment in the Fund decreases in value.

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. Securities in the Fund's portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Interest Rate and Credit Risk. The Fund's investments in bonds and other debt securities will change in value based on changes in interest rates. If rates rise, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate Loans and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given the historically low interest rate environment, risks associated with rising rates are heightened. The Fund's investments are subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund's investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund's securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer's securities.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares' values may fluctuate in response to events affecting that industry or sector.

Foreign Securities, Emerging Markets, and Currency Risk. The Fund may invest all of its assets in securities denominated in foreign currencies. Investments in foreign currencies, 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, sanctions or other measures by the United States or other governments, 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 or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. 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. These risks are magnified in countries in "emerging markets." Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers. While the Fund may engage in various strategies to hedge against currency risk, it is not required to do so.

Derivatives Risk. Derivatives, including futures contracts, options, forwards, swaps, and commodity linked derivatives, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund's original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including the credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate 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.

High Yield Securities and Loan Risk. The Fund invests in instruments including junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid. No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. The inability to dispose of the Fund's securities and other investments in a timely fashion could result in losses to the Fund. Because some instruments may have a more limited secondary market, liquidity risk is more pronounced for the Fund than for funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, the Fund may have to reinvest in instruments with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these instruments, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Mortgage-Related and Other Mortgage-Backed Securities Risk. The Fund may invest in both residential or commercial mortgage-related and mortgage-backed securities that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. In periods of rising interest rates, the Fund may be subject to extension risk, and may receive principal later than expected. As a result, in periods of rising interest rates, the Fund may exhibit additional volatility. During periods of difficult or frozen credit markets, significant changes in interest rates or deteriorating economic conditions, such securities may decline in value, face valuation difficulties, become more volatile and/or become 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 credit-worthiness 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.

MLP Risk. MLPs may trade infrequently and in limited volume and they may be subject to more abrupt or erratic price movements than securities of larger or more broadly-based companies. MLPs are subject to "commodity risks" as well as the risks associated with the specific industry or industries in which the partnership invests. In addition, the managing general partner of an MLP may receive an incentive allocation based on increases in the amount and growth of cash distributions to investors in the MLP. This method of compensation may create an incentive for the managing general partner to make investments that are riskier or more speculative than would be the case in the absence of such compensation arrangements. Certain MLPs may operate in, or have exposure to, the energy sector. The energy sector can be significantly affected by changes in the prices and supplies of oil and other energy fuels, energy conservation, the success of exploration projects, and tax and other government regulations, policies of the Organization of Petroleum Exporting Countries (OPEC) and relationships among OPEC members and between OPEC and oil importing nations.

Investment Company and Pooled Investment Vehicle Risk. The Fund may invest in shares of other investment companies, including closed-end funds, ETFs and other pooled investment vehicles, including those holding commodities, currencies or commodity futures. Shareholders bear both their proportionate share of the Fund's expenses and similar expenses of the investment company or pooled investment vehicle. ETFs and other investment companies or pooled investment vehicles that invest in commodities or currencies are subject to the risks associated with direct investments in commodities or currencies. The price and movement of an ETF, closed-end fund or pooled investment vehicle designed to track an index may not track the index and may result in a loss. In addition, closed-end funds that trade on an exchange often trade at a price below their net asset value (also known as a discount). Certain ETFs, closed-end funds or pooled investment vehicles traded on exchanges may be thinly traded and experience large spreads between the "ask" price quoted by a seller and the "bid" price offered by a buyer. There may be no active market for shares of certain closed-end funds or pooled investment vehicles (especially those not traded on exchanges) and such shares may be highly illiquid. 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.

Government Securities Risk. The Fund invests in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. 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 may not have the funds to meet their payment obligations in the future.

Inflation-Linked Securities Risk. Unlike conventional bonds, the principal or interest of inflation-linked securities such as TIPS is adjusted periodically to a specified rate of inflation (e.g., Consumer Price Index for all Urban Consumers (CPI-U)). There can be no assurance that the inflation index used will accurately measure the real rate of inflation. These securities may lose value in the event that the actual rate of inflation is different than the rate of the inflation index.

ETN Risk. Generally, ETNs are structured as senior, unsecured notes in which an issuer such as a bank agrees to pay a return based on the target commodity index less any fees. ETNs are synthetic instruments that allow individual investors to have access to derivatives linked to commodities and assets such as oil, Currencies and foreign stock indexes. ETNs combine certain aspects of bond and ETFs. Similar to ETFs, ETNs are traded on a major exchange (e.g., the New York Stock Exchange) during normal trading hours. However, investors can also hold the ETN until maturity. At maturity, the issuer pays to the investor a cash amount equal to the principal amount, subject to the day's index factor. ETN returns are based upon the performance of a market index minus applicable fees. The value of an ETN may be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying commodities markets, changes in the applicable interest rates, changes in the issuer's credit rating and economic, legal, political or geographic events that affect the referenced commodity.

The value of the ETN may drop due to a downgrade in the issuer's credit rating, even if the underlying index remains unchanged. Investments in ETNs are subject to the risks facing income securities in general including the risk that a counterparty will fail to make payments when due or default. In addition, investors in ETNs generally have no right with respect to the instruments underlying the index or any right to receive delivery of the instruments underlying the index.

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 the short sale and the date on which the fund purchases the security to replace the borrowed security. In addition, a lender may request, or market conditions may dictate, that securities sold short be returned to the lender on short notice, and the Fund may have to buy the securities sold short at an unfavorable price. If this occurs, any anticipated gain to the Fund may be reduced or eliminated or the short sale may result in a loss. The Fund's losses are potentially unlimited in a short sale transaction. 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.

Commodity Risk. Exposure to commodities, commodity-related securities and 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.

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.

High Portfolio Turnover Risk. The Fund may 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.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund's performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Select Class Shares has varied from year to year for the past five calendar years. The table shows the average annual total returns for the past one year, five years and life of the Fund. The table compares that performance to the MSCI World Index (net of foreign withholding taxes), the Bloomberg Barclays Global Aggregate Index — Unhedged USD (new benchmark), the Bloomberg Barclays U.S. Aggregate Index (old benchmark), the Global Allocation Composite Benchmark, comprised of 60% MSCI World Index (net of foreign withholding taxes) and 40% Bloomberg Barclays Global Aggregate Index — Unhedged USD, and the Lipper Flexible Portfolio Funds Index. The Lipper index is based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other indexes, the Lipper index includes the fees and expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will performance in the future.

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. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 2/28/18 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

IF YOU SELL YOUR SHARES, YOUR COST WOULD BE:

Expense Example - A, C, Select Shares - JPMorgan Income Builder Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	523	743	980	1,659
CLASS C SHARES	227	462	821	1,830
SELECT CLASS SHARES	61	238	429	982

IF YOU DO NOT SELL YOUR SHARES, YOUR COST
WOULD BE:

Expense Example, No Redemption - A, C, Select Shares - JPMorgan Income Builder Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	523	743	980	1,659
CLASS C SHARES	127	462	821	1,830
SELECT CLASS SHARES	61	238	429	982

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. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 52% of the average value of its portfolio.

What are the Fund’s main investment strategies?

The Fund has significant flexibility to achieve its investment objective and invests in a broad range of income-producing securities, including debt and equity securities in the U.S. and other markets throughout the world, both developed and emerging. There is no limit on the number of countries in which the Fund may invest, and the Fund may focus its investments in a single country or a small group of countries. As attractive investments across asset classes and strategies arise, the adviser attempts to capture these opportunities and has wide latitude to allocate the Fund’s assets among strategies and asset classes. J.P Morgan Investment Management, Inc. (JPMIM or the adviser) buys and sells securities and investments for the Fund based on the adviser’s view of strategies, sectors, and overall portfolio construction taking into account income generation, risk/return analyses, and relative value considerations.

The Fund may invest up to 100% of its total assets in debt securities and other types of investments that are below investment grade. With respect to below investment grade debt securities (known as junk bonds), the Fund currently expects to invest no more than 70% of its total assets in such securities. The Fund may also invest up to 35% of its total assets in loan assignments and participations (Loans) and commitments to purchase loan assignments (Unfunded Commitments). The Fund may invest up to 60% of its total assets in equity securities, including common stocks and equity securities of real estate investment trusts (REITs). In addition to investments in equity securities, the Fund may also invest up to 25% in preferred stocks and convertible securities that have characteristics of both equity and debt securities. The Fund has broad discretion to use other types of equity, debt, and investments that have characteristics of both debt and equity securities as part of its principal investment strategies. These include mortgage-backed, mortgage-related and asset-backed securities, including collateralized mortgage obligations and principal-only (PO) and interest-only (IO) stripped mortgage-backed securities, dollar rolls, REITs, inflation-linked securities including Treasury Inflation Protected Securities (TIPS), when-issued securities and forward commitments, exchange traded funds (ETFs), affiliated investment companies and other investment companies including closed-end funds.

In addition to direct investments in securities, derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. The Fund may use futures contracts, foreign currency transactions, options and swaps to help manage duration, sector and yield curve exposure and credit and spread volatility. The Fund may also use such derivatives to manage equity, country, regional and currency exposure, to increase income or gain to the Fund, for hedging and for risk management. The Fund may hedge its non-dollar investments back to the U.S. dollar through the use of foreign currency derivatives including forward foreign currency contracts and currency futures, but may not always do so. In addition to hedging non-dollar investments, the Fund may use such derivatives to increase income and gain to the Fund and/or as part of its risk management process by establishing or adjusting exposure to particular foreign securities, markets or currencies.

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 instruments 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

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. Securities in the Fund’s portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

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. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

High Yield Securities and Loan Risk. The Fund may invest in securities including junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid. No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. The inability to dispose of the Fund’s securities and other investments in a timely fashion could result in losses to the Fund. Because some instruments may have a more limited secondary market, liquidity risk is more pronounced for the Fund than for funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, the Fund may have to reinvest in instruments with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these instruments, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Interest Rate and Credit Risk. The Fund’s investments in bonds and other debt securities will change in value based on changes in interest rates. If rates rise, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate Loans and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given the historically low interest rate environment, risks associated with rising rates are heightened. The Fund’s investments are subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Foreign Securities, Emerging Markets, and Currency Risk. The Fund may invest all of its assets in securities denominated in foreign currencies. Investments in foreign currencies, foreign issuers and foreign securities (including depository receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, sanctions or other measures by the United States or other governments, 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 or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. 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. These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers. While the Fund may engage in various strategies to hedge against currency risk, it is not required to do so. The Fund may focus its investments in a single country or a small group of countries and be subject to greater volatility than a more geographically diversified fund.

European Market Risk. The Fund’s performance will be affected by political, social and economic conditions in Europe, such as growth of the economic output (the gross national product), the rate of inflation, the rate at which capital is reinvested into European economies, the success of governmental actions to reduce budget deficits, the resource self-sufficiency of European countries and interest and monetary exchange rates between European countries. European financial markets may experience volatility due to concerns about high government debt levels, credit rating downgrades, rising unemployment, the future of the euro as a common currency, possible restructuring of government debt and other government measures responding to those concerns, and fiscal and monetary controls imposed on member countries of the European Union. The risk of investing in Europe may be heightened due to the referendum in which the United Kingdom voted to exit the European Union. In addition, if one or more countries were to exit the European Union or abandon the use of the euro as a currency, the value of investments tied to those countries or the euro could decline significantly and unpredictably.

Asset-Backed, Mortgage-Related and Mortgage-Backed Securities Risk. The Fund may invest in asset-backed, mortgage-related and mortgage-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. In periods of rising interest rates, the Fund may be subject to extension risk, and may receive principal later than expected. As a result, in periods of rising interest rates, the Fund may exhibit additional volatility. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, such securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. Collateralized mortgage obligations (CMOs) and stripped mortgage-backed securities, including those structured as IOs and POs, are more volatile and may be more sensitive to the rate of prepayments than other mortgage-related securities.

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 generally rank senior to common stock in a corporation’s capital structure but 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.

Preferred Stock Risk. Preferred stock generally has a preference as to dividends and liquidation over an issuer’s common stock but ranks junior to debt securities in an issuer’s capital structure. Unlike interest payments on debt securities, preferred stock dividends are payable only if declared by the issuer’s board of directors. Preferred stock also may be subject to optional or mandatory redemption provisions.

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.

Derivatives Risk. Derivatives, including futures contracts, foreign currency transactions, options, swaps, forward foreign currency contracts, and currency futures, 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 expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). 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. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the currency, security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improperly valuation. Certain of the Fund’s transactions in foreign currency derivatives and other derivatives could also affect the amount, timing and character of distributions to shareholders which may result in the Fund realizing more short-term capital gain and ordinary income subject to tax at ordinary income tax rates than it would if it did not engage in such transactions, which may adversely impact the Fund’s after-tax returns. In addition, the Fund may use derivatives for non-hedging purposes, which increases the Fund’s potential for loss.

Government Securities Risk. The Fund invests in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. 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 will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

ETF and Investment Company Risk. Shareholders bear both their proportionate share of the Fund’s expenses and similar expenses of an ETF or other investment company. The price and 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).

Inflation-Linked Security Risk. Inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of an inflation-linked security tends to decline when real interest rates increase. Unlike conventional bonds, the principal and interest payments of inflation-linked securities such as TIPS are adjusted periodically to a specified rate of inflation (e.g., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). There can be no assurance that the inflation index used will accurately measure the real rate of inflation. These securities may lose value in the event that the actual rate of inflation is different than the rate of the inflation index.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

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.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how performance of the Fund’s Class A Shares has varied from year to year over the past nine calendar years. The table shows the average annual total returns for the past one year, five years and life of the Fund. The table compares that performance to the MSCI World Index (net of foreign withholding taxes), the Bloomberg Barclays U.S. Aggregate Index, the Income Builder Composite Benchmark, composed of 60% of the MSCI World Index (net of foreign withholding taxes) and 40% Bloomberg Barclays U.S. Aggregate Index, and the Lipper Flexible Portfolio Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other indexes, the Lipper index includes the fees and expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Subsequent to the inception of the Fund on 5/31/07 until 12/18/09, the Fund did not experience any shareholder purchase and sale activity. If such shareholder activity had occurred, the Fund’s performance may have been impacted. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111. The performance figures in the bar chart do not reflect any deduction for the front-end sales charge which is assessed on Class A Shares. If the sales charge were reflected, the performance figures would have been lower.

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund has significant flexibility to achieve its investment objective and invests in a broad range of income-producing securities, including debt and equity securities in the U.S. and other markets throughout the world, both developed and emerging. There is no limit on the number of countries in which the Fund may invest, and the Fund may focus its investments in a single country or a small group of countries. As attractive investments across asset classes and strategies arise, the adviser attempts to capture these opportunities and has wide latitude to allocate the Fund’s assets among strategies and asset classes. J.P Morgan Investment Management, Inc. (JPMIM or the adviser) buys and sells securities and investments for the Fund based on the adviser’s view of strategies, sectors, and overall portfolio construction taking into account income generation, risk/return analyses, and relative value considerations.

The Fund may invest up to 100% of its total assets in debt securities and other types of investments that are below investment grade. With respect to below investment grade debt securities (known as junk bonds), the Fund currently expects to invest no more than 70% of its total assets in such securities. The Fund may also invest up to 35% of its total assets in loan assignments and participations (Loans) and commitments to purchase loan assignments (Unfunded Commitments). The Fund may invest up to 60% of its total assets in equity securities, including common stocks and equity securities of real estate investment trusts (REITs). In addition to investments in equity securities, the Fund may also invest up to 25% in preferred stocks and convertible securities that have characteristics of both equity and debt securities. The Fund has broad discretion to use other types of equity, debt, and investments that have characteristics of both debt and equity securities as part of its principal investment strategies. These include mortgage-backed, mortgage-related and asset-backed securities, including collateralized mortgage obligations and principal-only (PO) and interest-only (IO) stripped mortgage-backed securities, dollar rolls, REITs, inflation-linked securities including Treasury Inflation Protected Securities (TIPS), when-issued securities and forward commitments, exchange traded funds (ETFs), affiliated investment companies and other investment companies including closed-end funds.

In addition to direct investments in securities, derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. The Fund may use futures contracts, foreign currency transactions, options and swaps to help manage duration, sector and yield curve exposure and credit and spread volatility. The Fund may also use such derivatives to manage equity, country, regional and currency exposure, to increase income or gain to the Fund, for hedging and for risk management. The Fund may hedge its non-dollar investments back to the U.S. dollar through the use of foreign currency derivatives including forward foreign currency contracts and currency futures, but may not always do so. In addition to hedging non-dollar investments, the Fund may use such derivatives to increase income and gain to the Fund and/or as part of its risk management process by establishing or adjusting exposure to particular foreign securities, markets or currencies.

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 instruments 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

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. Securities in the Fund’s portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

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. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

High Yield Securities and Loan Risk. The Fund may invest in securities including junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid. No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. The inability to dispose of the Fund’s securities and other investments in a timely fashion could result in losses to the Fund. Because some instruments may have a more limited secondary market, liquidity risk is more pronounced for the Fund than for funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, the Fund may have to reinvest in instruments with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these instruments, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Interest Rate and Credit Risk. The Fund’s investments in bonds and other debt securities will change in value based on changes in interest rates. If rates rise, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate Loans and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given the historically low interest rate environment, risks associated with rising rates are heightened. The Fund’s investments are subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Foreign Securities, Emerging Markets, and Currency Risk. The Fund may invest all of its assets in securities denominated in foreign currencies. Investments in foreign currencies, foreign issuers and foreign securities (including depository receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, sanctions or other measures by the United States or other governments, 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 or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. 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. These risks are magnified in countries in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers. While the Fund may engage in various strategies to hedge against currency risk, it is not required to do so. The Fund may focus its investments in a single country or a small group of countries and be subject to greater volatility than a more geographically diversified fund.

European Market Risk. The Fund’s performance will be affected by political, social and economic conditions in Europe, such as growth of the economic output (the gross national product), the rate of inflation, the rate at which capital is reinvested into European economies, the success of governmental actions to reduce budget deficits, the resource self-sufficiency of European countries and interest and monetary exchange rates between European countries. European financial markets may experience volatility due to concerns about high government debt levels, credit rating downgrades, rising unemployment, the future of the euro as a common currency, possible restructuring of government debt and other government measures responding to those concerns, and fiscal and monetary controls imposed on member countries of the European Union. The risk of investing in Europe may be heightened due to the referendum in which the United Kingdom voted to exit the European Union. In addition, if one or more countries were to exit the European Union or abandon the use of the euro as a currency, the value of investments tied to those countries or the euro could decline significantly and unpredictably.

Asset-Backed, Mortgage-Related and Mortgage-Backed Securities Risk. The Fund may invest in asset-backed, mortgage-related and mortgage-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. In periods of rising interest rates, the Fund may be subject to extension risk, and may receive principal later than expected. As a result, in periods of rising interest rates, the Fund may exhibit additional volatility. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, such securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. Collateralized mortgage obligations (CMOs) and stripped mortgage-backed securities, including those structured as IOs and POs, are more volatile and may be more sensitive to the rate of prepayments than other mortgage-related securities.

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 generally rank senior to common stock in a corporation’s capital structure but 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.

Preferred Stock Risk. Preferred stock generally has a preference as to dividends and liquidation over an issuer’s common stock but ranks junior to debt securities in an issuer’s capital structure. Unlike interest payments on debt securities, preferred stock dividends are payable only if declared by the issuer’s board of directors. Preferred stock also may be subject to optional or mandatory redemption provisions.

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.

Derivatives Risk. Derivatives, including futures contracts, foreign currency transactions, options, swaps, forward foreign currency contracts, and currency futures, 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 expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). 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. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the currency, security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improperly valuation. Certain of the Fund’s transactions in foreign currency derivatives and other derivatives could also affect the amount, timing and character of distributions to shareholders which may result in the Fund realizing more short-term capital gain and ordinary income subject to tax at ordinary income tax rates than it would if it did not engage in such transactions, which may adversely impact the Fund’s after-tax returns. In addition, the Fund may use derivatives for non-hedging purposes, which increases the Fund’s potential for loss.

Government Securities Risk. The Fund invests in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. 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 will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

ETF and Investment Company Risk. Shareholders bear both their proportionate share of the Fund’s expenses and similar expenses of an ETF or other investment company. The price and 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).

Inflation-Linked Security Risk. Inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of an inflation-linked security tends to decline when real interest rates increase. Unlike conventional bonds, the principal and interest payments of inflation-linked securities such as TIPS are adjusted periodically to a specified rate of inflation (e.g., Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U)). There can be no assurance that the inflation index used will accurately measure the real rate of inflation. These securities may lose value in the event that the actual rate of inflation is different than the rate of the inflation index.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

This section provides some indication of the risks of investing in the Fund. The bar chart shows how performance of the Fund’s Class A Shares has varied from year to year over the past nine calendar years. The table shows the average annual total returns for the past one year, five years and life of the Fund. The table compares that performance to the MSCI World Index (net of foreign withholding taxes), the Bloomberg Barclays U.S. Aggregate Index, the Income Builder Composite Benchmark, composed of 60% of the MSCI World Index (net of foreign withholding taxes) and 40% Bloomberg Barclays U.S. Aggregate Index, and the Lipper Flexible Portfolio Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other indexes, the Lipper index includes the fees and expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Subsequent to the inception of the Fund on 5/31/07 until 12/18/09, the Fund did not experience any shareholder purchase and sale activity. If such shareholder activity had occurred, the Fund’s performance may have been impacted. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111. The performance figures in the bar chart do not reflect any deduction for the front-end sales charge which is assessed on Class A Shares. If the sales charge were reflected, the performance figures would have been lower.

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. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 2/28/18 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

IF YOU SELL YOUR SHARES, YOUR COST WOULD BE:

Expense Example - A, C, Select Shares - JPMorgan Systematic Alpha Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	572	916	1,283	2,313
CLASS C SHARES	278	655	1,159	2,546
SELECT CLASS SHARES	102	410	741	1,676

IF YOU DO NOT SELL YOUR SHARES, YOUR COST
WOULD BE:

Expense Example, No Redemption - A, C, Select Shares - JPMorgan Systematic Alpha Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	572	916	1,283	2,313
CLASS C SHARES	178	655	1,159	2,546
SELECT CLASS SHARES	102	410	741	1,676

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. The Fund’s portfolio turnover rate was 151% of the average value of its portfolio.

What are the Fund’s main investment strategies?

J.P. Morgan Investment Management Inc., the Fund’s investment adviser (the adviser), believes that it has identified a set of return sources present in markets, such as equities, fixed income, convertible bonds, currencies and commodities, that result from, among other things, assuming a particular risk or taking advantage of a behavioral bias (each a “return factor”). For example, an investor may expect a higher return over time when investing in small cap stocks compared to large cap stocks due to the additional risks often posed by small cap stocks. The adviser may allocate assets to this “small cap return factor” by employing a strategy that purchases small cap stocks and shorts large cap stocks in an attempt to capture the risk premium typically associated with investing in small cap companies relative to large cap companies. Additionally, the adviser may gain exposure to a “momentum return factor” by employing a strategy that buys stocks with strong positive price momentum and shorts stocks with strong negative price momentum. This strategy would seek to exploit a behavioral bias present in the market, in which investors tend to purchase stocks that have recently performed well, thereby helping to contribute to continued positive price movement, and sell stocks that have recently performed poorly, thereby helping to contribute to continued negative price movement. Under normal market conditions, the Fund seeks to achieve its investment objective by employing alternative investment strategies to access certain of these return factors. The return factors the adviser will seek to access have historically presented a low correlation to each other and to traditional asset classes and have unique risk and return profiles, and by employing this return factor based approach, the Fund seeks to provide total returns over time while maintaining a relatively low correlation with traditional asset classes.

The adviser will use a proprietary investment model to allocate assets to a subset of return factors. The return factors identified by the adviser include equity based return factors, fixed income based return factors, convertible bond based return factors, currency based return factors and commodity based return factors. The alternative investment strategies the Fund may employ to gain exposure to return factors include equity market neutral, event driven, convertible arbitrage and macro based strategies. “Systematic” in the Fund’s name refers to the adviser’s model-driven investment process and “Alpha” in the Fund’s name refers to the adviser’s attempt to identify individual return factors that are expected to contribute to the Fund’s total return.

The instruments in which the Fund may invest, either directly or through the use of derivatives, include equity securities, debt securities, convertible securities, commodities and currencies. The amount that may be invested in any one instrument will vary and generally depends on the investment strategies employed by the adviser at that point in 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, and may invest in below investment grade instruments (junk bonds). The Fund may have both long and short exposure to these instruments.

The adviser will make use of derivatives, including swaps, futures and forwards, in implementing its strategies. Under normal market conditions, the adviser currently expects that a significant portion of the Fund’s exposure will be attained through the use of derivatives, in addition to its exposure through direct investments. Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, will primarily be used as an efficient means of implementing a particular strategy in order to gain exposure to a desired return factor. For example, in implementing equity market neutral strategies and macro based strategies, the Fund may use a total return swap to establish both long and short positions in order to gain the desired exposure rather than physically purchasing and selling short each instrument. Derivatives may also be used to increase gain, to effectively gain targeted equity exposure from its cash positions, to hedge various investments and/or for risk management. 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, and other short-term investments, including commercial paper, time deposits and money market funds.

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 contribution to the Fund’s overall volatility. In allocating assets, the adviser seeks to approximately equal risk weight to the individual return factors over the long term, although the exposure to individual return factors will vary based on, among other things, the opportunity the adviser sees in each individual return factor.

The Fund will gain exposure to commodity markets by investing up to 15% of its total assets in the Systematic Alpha Fund CS 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 related investments, including derivative instruments 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 may hold instruments described elsewhere in this prospectus that are not commodity related and 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 return factor based approach will achieve any particular level of return or will, in fact, reduce volatility or potential loss. The Fund’s returns over time or during any period may be negative and the Fund may underperform the overall security markets over time or during any particular period.

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 instruments 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

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. Securities in the Fund’s portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

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”.

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 decreases in value.

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 Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and vulnerable to economic, market and industry changes than securities of larger more established companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

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, sanctions or other measures by the United States or other governments, 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 or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. 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. These risks are magnified in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

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 declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given the historically low interest rate environment, risks associated with rising rates are heightened. The Fund’s investments are subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

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 economic changes, valuation difficulties, and potential illiquidity. 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 securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. 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 will provide financial support. Therefore, U.S. government related organizations 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.

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 impacted by that currency loses value because that currency is worth less in U.S. dollars. Currency exchange rates may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates. 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. Although the Fund may attempt to hedge its currency exposure into the U.S. dollar, it may not be successful in reducing 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.

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, 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.

Under normal market conditions, the adviser currently expects that a significant portion of the Fund’s exposure will be attained through the use of derivatives. Investing in derivatives will result in a form of leverage, which may be significant. 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 may also be subject to risks related to swap agreements, including total return swaps. Total return swaps are contracts in which one party agrees to make periodic payments based on the change in market value of the underlying assets, which may include a specified security, basket of securities or securities indices during the specified period, in return for periodic payments based on a fixed or variable interest rate or the total return from other underlying assets. Total return swaps may be used to obtain exposure to a security or market without owning or taking physical custody of such security or market and may be used 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’s returns are reduced or its losses increased by the costs associated with the swap, which may be significant. In addition, there is the risk that the swap may be terminated by the Fund or the counterparty in accordance with its terms or as a result of regulatory changes. If the swap were to terminate, the Fund may be unable to employ its investment strategy and may suffer losses. The Fund will segregate or earmark liquid assets at its custodian bank in an amount sufficient to cover its obligations under swap agreements.

Subsidiary and Tax 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 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. 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.

The Fund has not received a private letter ruling from the Internal Revenue Service (the IRS) with respect to income derived from its investment in the Subsidiary. The Fund relies on the reasoning of private letter rulings from the IRS to other taxpayers with respect to its investment in the Subsidiary. There can be no assurance that the IRS will not change its position that income derived from commodity-linked notes and wholly-owned subsidiaries is qualifying income. The tax treatment of commodity-linked notes, other commodity-linked derivatives and the Fund’s investments in the Subsidiary may be adversely affected by future legislation, Treasury regulations and/or guidance issued by the IRS that could affect whether income from such investments is qualifying income under Subchapter M of the Internal Revenue Code of 1986, as amended, or otherwise alter the character, timing and/or amount of the Fund’s taxable income or any gains and distributions made by the Fund.

Model and Data Risk. Given the complexity of the investments and strategies of the Fund, the adviser will make use of quantitative models and information and data supplied by third parties to, among other things, help determine the portfolio’s asset allocation weightings and construct sets of transactions and investments. To the extent the models used by the adviser or the information and data supplied by third parties are incorrect or incomplete, the decisions made by the adviser in reliance thereon will expose the Fund to potential risks and could lead to the Fund incurring losses on its investments.

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.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

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.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

J.P. Morgan Investment Management Inc., the Fund’s investment adviser (the adviser), believes that it has identified a set of return sources present in markets, such as equities, fixed income, convertible bonds, currencies and commodities, that result from, among other things, assuming a particular risk or taking advantage of a behavioral bias (each a “return factor”). For example, an investor may expect a higher return over time when investing in small cap stocks compared to large cap stocks due to the additional risks often posed by small cap stocks. The adviser may allocate assets to this “small cap return factor” by employing a strategy that purchases small cap stocks and shorts large cap stocks in an attempt to capture the risk premium typically associated with investing in small cap companies relative to large cap companies. Additionally, the adviser may gain exposure to a “momentum return factor” by employing a strategy that buys stocks with strong positive price momentum and shorts stocks with strong negative price momentum. This strategy would seek to exploit a behavioral bias present in the market, in which investors tend to purchase stocks that have recently performed well, thereby helping to contribute to continued positive price movement, and sell stocks that have recently performed poorly, thereby helping to contribute to continued negative price movement. Under normal market conditions, the Fund seeks to achieve its investment objective by employing alternative investment strategies to access certain of these return factors. The return factors the adviser will seek to access have historically presented a low correlation to each other and to traditional asset classes and have unique risk and return profiles, and by employing this return factor based approach, the Fund seeks to provide total returns over time while maintaining a relatively low correlation with traditional asset classes.

The adviser will use a proprietary investment model to allocate assets to a subset of return factors. The return factors identified by the adviser include equity based return factors, fixed income based return factors, convertible bond based return factors, currency based return factors and commodity based return factors. The alternative investment strategies the Fund may employ to gain exposure to return factors include equity market neutral, event driven, convertible arbitrage and macro based strategies. “Systematic” in the Fund’s name refers to the adviser’s model-driven investment process and “Alpha” in the Fund’s name refers to the adviser’s attempt to identify individual return factors that are expected to contribute to the Fund’s total return.

The instruments in which the Fund may invest, either directly or through the use of derivatives, include equity securities, debt securities, convertible securities, commodities and currencies. The amount that may be invested in any one instrument will vary and generally depends on the investment strategies employed by the adviser at that point in 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, and may invest in below investment grade instruments (junk bonds). The Fund may have both long and short exposure to these instruments.

The adviser will make use of derivatives, including swaps, futures and forwards, in implementing its strategies. Under normal market conditions, the adviser currently expects that a significant portion of the Fund’s exposure will be attained through the use of derivatives, in addition to its exposure through direct investments. Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, will primarily be used as an efficient means of implementing a particular strategy in order to gain exposure to a desired return factor. For example, in implementing equity market neutral strategies and macro based strategies, the Fund may use a total return swap to establish both long and short positions in order to gain the desired exposure rather than physically purchasing and selling short each instrument. Derivatives may also be used to increase gain, to effectively gain targeted equity exposure from its cash positions, to hedge various investments and/or for risk management. 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, and other short-term investments, including commercial paper, time deposits and money market funds.

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 contribution to the Fund’s overall volatility. In allocating assets, the adviser seeks to approximately equal risk weight to the individual return factors over the long term, although the exposure to individual return factors will vary based on, among other things, the opportunity the adviser sees in each individual return factor.

The Fund will gain exposure to commodity markets by investing up to 15% of its total assets in the Systematic Alpha Fund CS 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 related investments, including derivative instruments 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 may hold instruments described elsewhere in this prospectus that are not commodity related and 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 return factor based approach will achieve any particular level of return or will, in fact, reduce volatility or potential loss. The Fund’s returns over time or during any period may be negative and the Fund may underperform the overall security markets over time or during any particular period.

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 instruments 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

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. Securities in the Fund’s portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

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”.

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 decreases in value.

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 Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and vulnerable to economic, market and industry changes than securities of larger more established companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

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, sanctions or other measures by the United States or other governments, 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 or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. 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. These risks are magnified in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

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 declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given the historically low interest rate environment, risks associated with rising rates are heightened. The Fund’s investments are subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

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 economic changes, valuation difficulties, and potential illiquidity. 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 securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. 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 will provide financial support. Therefore, U.S. government related organizations 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.

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 impacted by that currency loses value because that currency is worth less in U.S. dollars. Currency exchange rates may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates. 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. Although the Fund may attempt to hedge its currency exposure into the U.S. dollar, it may not be successful in reducing 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.

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, 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.

Under normal market conditions, the adviser currently expects that a significant portion of the Fund’s exposure will be attained through the use of derivatives. Investing in derivatives will result in a form of leverage, which may be significant. 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 may also be subject to risks related to swap agreements, including total return swaps. Total return swaps are contracts in which one party agrees to make periodic payments based on the change in market value of the underlying assets, which may include a specified security, basket of securities or securities indices during the specified period, in return for periodic payments based on a fixed or variable interest rate or the total return from other underlying assets. Total return swaps may be used to obtain exposure to a security or market without owning or taking physical custody of such security or market and may be used 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’s returns are reduced or its losses increased by the costs associated with the swap, which may be significant. In addition, there is the risk that the swap may be terminated by the Fund or the counterparty in accordance with its terms or as a result of regulatory changes. If the swap were to terminate, the Fund may be unable to employ its investment strategy and may suffer losses. The Fund will segregate or earmark liquid assets at its custodian bank in an amount sufficient to cover its obligations under swap agreements.

Subsidiary and Tax 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 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. 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.

The Fund has not received a private letter ruling from the Internal Revenue Service (the IRS) with respect to income derived from its investment in the Subsidiary. The Fund relies on the reasoning of private letter rulings from the IRS to other taxpayers with respect to its investment in the Subsidiary. There can be no assurance that the IRS will not change its position that income derived from commodity-linked notes and wholly-owned subsidiaries is qualifying income. The tax treatment of commodity-linked notes, other commodity-linked derivatives and the Fund’s investments in the Subsidiary may be adversely affected by future legislation, Treasury regulations and/or guidance issued by the IRS that could affect whether income from such investments is qualifying income under Subchapter M of the Internal Revenue Code of 1986, as amended, or otherwise alter the character, timing and/or amount of the Fund’s taxable income or any gains and distributions made by the Fund.

Model and Data Risk. Given the complexity of the investments and strategies of the Fund, the adviser will make use of quantitative models and information and data supplied by third parties to, among other things, help determine the portfolio’s asset allocation weightings and construct sets of transactions and investments. To the extent the models used by the adviser or the information and data supplied by third parties are incorrect or incomplete, the decisions made by the adviser in reliance thereon will expose the Fund to potential risks and could lead to the Fund incurring losses on its investments.

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.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

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.

JPMorgan Global Allocation Fund

Class/Ticker: R2/GAONX

What is the goal of the Fund?

The Fund seeks to maximize long-term total return.

Fees and Expenses of the Fund

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

“Acquired Fund Fees and Expenses” are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies, including affiliated money market funds, other mutual funds, exchange-traded funds and business development companies. The impact of Acquired Fund Fees and Expenses is included in the total returns of the Fund. Acquired Fund Fees and Expenses are not direct costs of the Fund, are not used to calculate the Fund’s net asset value per share and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus.

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. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 64% of the average value of its portfolio.

What are the Fund’s main investment strategies?

The Fund has significant flexibility to invest in a broad range of equity, fixed income and alternative asset classes in the U.S. and other markets throughout the world, both developed and emerging. J.P. Morgan Investment Management Inc. (JPMIM or adviser) uses a flexible asset allocation approach in constructing the Fund’s portfolio. Under normal circumstances, the Fund will invest at least 40% of its total assets in countries other than the United States (Non-U.S. Countries) unless the adviser determines, in its sole discretion, that conditions are not favorable. If the adviser determines that conditions are not favorable, the Fund may invest under 40% of its total assets in Non-U.S. Countries provided that the Fund will not invest less than 30% of its total assets in Non-U.S. Countries under normal circumstances except for temporary defensive purposes. In managing the Fund, the adviser will invest in issuers in at least three countries other than the U.S. under normal circumstances. The Fund will invest across the full range of asset classes. Ranges for broad asset classes are:

Global Equity	10-90	%
Global Fixed Income	10-90	%
Alternatives	0-60	%
Cash and Cash Equivalents	0-80	%

The Fund’s equity investments may include common stock, preferred stock, exchange traded funds (ETFs), convertible securities, depositary receipts, warrants to buy common stocks, master limited partnerships (MLPs), and J.P. Morgan Funds. The Fund is generally unconstrained by any particular capitalization with regard to its equity investments.

The Fund’s fixed income investments may include bank obligations, convertible securities, U.S. government securities (including agencies and instrumentalities), mortgage-backed and mortgage-related securities (which may include securities that are issued by non-governmental entities), domestic and foreign corporate bonds, high yield securities (junk bonds), loan assignments and participations (Loans), debt obligations issued or guaranteed by a foreign sovereign government or its agencies, authorities or political subdivisions, floating rate securities, inflation-indexed bonds, inflation-linked securities such as Treasury Inflation Protected Securities (TIPS), J.P. Morgan Funds, and ETFs. The Fund is generally unconstrained with regard to the duration of its fixed income investments.

The Fund’s alternative investments include securities that are not a part of the Fund’s global equity or global fixed income investments. These investments may include individual securities (such as convertible securities, inflation-sensitive securities and preferred stock), J.P. Morgan Funds, ETFs, exchange traded notes (ETNs) and exchange traded commodities (ETCs). The investments in this asset class may give the Fund exposure to: market neutral strategies, long/short strategies, real estate (including real estate investment trusts (REITS)), currencies and commodities.

The Fund may invest in ETFs in order to gain exposure to particular asset classes. The Fund expects that, to the extent it invests in ETFs, it will primarily invest in passively managed ETFs. A passively managed ETF is a registered investment company that seeks to track the performance of a particular market index or security. These indexes include not only broad-based market indexes but more specific indexes as well, including those relating to particular sectors, markets, regions, industries or factors.

In addition to direct investments in securities, derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may also be used as substitutes for securities in which the Fund can invest. For example, in implementing equity market neutral strategies and macro based strategies, the Fund may use a total return swap to establish both long and short positions in order to gain the desired exposure rather than physically purchasing and selling short each instrument. The Fund may use futures contracts, options, forwards, and swaps to more effectively gain targeted equity and fixed income exposure from its cash positions, to hedge investments, for risk management and to attempt to increase the Fund’s gain. The Fund may use futures contracts, forward contracts, options (including options on interest rate futures contracts and interest rate swaps), swaps, and credit default swaps to help manage duration, sector and yield curve exposure and credit and spread volatility. The Fund may utilize exchange traded futures contracts for cash management and to gain exposure to equities pending investment in individual securities. To the extent that the Fund does not utilize underlying funds to gain exposure to commodities, it may utilize commodity linked derivatives or commodity swaps to gain exposure to commodities.

The Fund may invest in securities denominated in any currency. The Fund may utilize forward currency transactions to hedge exposure to non-dollar investments back to the U.S. dollar.

As part of the underlying strategies, the Fund may enter into short sales. In short selling transactions, the Fund sells a security it does not own in anticipation of a decline in the market value of the security. To complete the transaction, the Fund must borrow the security to make delivery to the buyer. The Fund is obligated to replace the security borrowed by purchasing it subsequently at the market price at the time of replacement.

The Fund will likely engage in active and frequent trading.

Investment Process: As attractive investments across asset classes and strategies arise, the adviser attempts to capture these opportunities and has wide latitude to allocate the Fund’s assets among strategies and asset classes. The adviser establishes the strategic and tactical allocation for the Fund and makes decisions concerning strategies, sectors, and overall portfolio construction. The adviser develops its investment insights through the combination of top-down macro views, together with the bottom-up views of the separate asset class specialists within J.P. Morgan Asset Management globally.

In buying and selling investments for the Fund, the adviser employs a continuous four-step process: (1) making asset allocation decisions based on JPMIM’s assessment of the intermediate term (6–18 months) market outlook; (2) constructing the portfolio after considering the Fund’s risk and return target, by determining the weightings of the asset classes, selecting the underlying securities, funds and other instruments; (3) analyzing the investment capabilities of the underlying portfolio managers and funds, and (4) monitoring portfolio exposures and weightings and rebalancing portfolio exposures and weightings in response to market price action and changes in JPMIM’s shorter term market outlook.

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 instruments 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

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. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

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. Securities in the Fund’s portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Interest Rate and Credit Risk. The Fund’s investments in bonds and other debt securities will change in value based on changes in interest rates. If rates rise, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate Loans and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given the historically low interest rate environment, risks associated with rising rates are heightened. The Fund’s investments are subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Foreign Securities, Emerging Markets, and Currency Risk. The Fund may invest all of its assets in securities denominated in foreign currencies. Investments in foreign currencies, 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, sanctions or other measures by the United States or other governments, 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 or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. 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. These risks are magnified in countries in “emerging markets.” Emerging Market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers. While the Fund may engage in various strategies to hedge against currency risk, it is not required to do so.

Derivatives Risk. Derivatives, including futures contracts, options, forwards, swaps and commodity linked derivatives, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including the credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate 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.

High Yield Securities and Loan Risk. The Fund invests in instruments including junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid. No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. The inability to dispose of the Fund’s securities and other investments in a timely fashion could result in losses to the Fund. Because some instruments may have a more limited secondary market, liquidity risk is more pronounced for the Fund than for funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, the Fund may have to reinvest in instruments with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these instruments, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Mortgage-Related and Other Mortgage-Backed Securities Risk. The Fund may invest in both residential or commercial mortgage-related and mortgage-backed securities that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. In periods of rising interest rates, the Fund may be subject to extension risk, and may receive principal later than expected. As a result, in periods of rising interest rates, the Fund may exhibit additional volatility. During periods of difficult or frozen credit markets, significant changes in interest rates or deteriorating economic conditions, such securities may decline in value, face valuation difficulties, become more volatile and/or become 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 credit-worthiness 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.

MLP Risk. MLPs may trade infrequently and in limited volume and they may be subject to more abrupt or erratic price movements than securities of larger or more broadly-based companies. MLPs are subject to “commodity risks” as well as the risks associated with the specific industry or industries in which the partnership invests. In addition, the managing general partner of an MLP may receive an incentive allocation based on increases in the amount and growth of cash distributions to investors in the MLP. This method of compensation may create an incentive for the managing general partner to make investments that are riskier or more speculative than would be the case in the absence of such compensation arrangements. Certain MLPs may operate in, or have exposure to, the energy sector. The energy sector can be significantly affected by changes in the prices and supplies of oil and other energy fuels, energy conservation, the success of exploration projects, and tax and other government regulations, policies of the Organization of Petroleum Exporting Countries (OPEC) and relationships among OPEC members and between OPEC and oil importing nations.

Investment Company and Pooled Investment Vehicle Risk. The Fund may invest in shares of other investment companies, including closed-end funds, ETFs and other pooled investment vehicles, including those holding commodities, currencies or commodity futures. Shareholders bear both their proportionate share of the Fund’s expenses and similar expenses of the investment company or pooled investment vehicle. ETFs and other investment companies or pooled investment vehicles that invest in commodities or currencies are subject to the risks associated with direct investments in commodities or currencies. The price and movement of an ETF, closed-end fund or pooled investment vehicle designed to track an index may not track the index and may result in a loss. In addition, closed-end funds that trade on an exchange often trade at a price below their net asset value (also known as a discount). Certain ETFs, closed-end funds or pooled investment vehicles traded on exchanges may be thinly traded and experience large spreads between the “ask” price quoted by a seller and the “bid” price offered by a buyer. There may be no active market for shares of certain closed-end funds or pooled investment vehicles (especially those not traded on exchanges) and such shares may be highly illiquid. 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.

Government Securities Risk. The Fund invests in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. 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 may not have the funds to meet their payment obligations in the future.

Inflation-Linked Securities Risk. Unlike conventional bonds, the principal or interest of inflation-linked securities such as TIPS is adjusted periodically to a specified rate of inflation (e.g., Consumer Price Index for all Urban Consumers (CPI-U)). There can be no assurance that the inflation index used will accurately measure the real rate of inflation. These securities may lose value in the event that the actual rate of inflation is different than the rate of the inflation index.

ETN Risk. Generally, ETNs are structured as senior, unsecured notes in which an issuer such as a bank agrees to pay a return based on the target commodity index less any fees. ETNs are synthetic instruments that allow individual investors to have access to derivatives linked to commodities and assets such as oil, Currencies and foreign stock indexes. ETNs combine certain aspects of bond and ETFs. Similar to ETFs, ETNs are traded on a major exchange (e.g., the New York Stock Exchange) during normal trading hours. However, investors can also hold the ETN until maturity. At maturity, the issuer pays to the investor a cash amount equal to the principal amount, subject to the day’s index factor. ETN returns are based upon the performance of a market index minus applicable fees. The value of an ETN may be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying commodities markets, changes in the applicable interest rates, changes in the issuer’s credit rating and economic, legal, political or geographic events that affect the referenced commodity. The value of the ETN may drop due to a downgrade in the issuer’s credit rating, even if the underlying index remains unchanged. Investments in ETNs are subject to the risks facing income securities in general including the risk that a counterparty will fail to make payments when due or default. In addition, investors in ETNs generally have no right with respect to the instruments underlying the index or any right to receive delivery of the instruments underlying the index.

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 the short sale and the date on which the fund purchases the security to replace the borrowed security. In addition, a lender may request, or market conditions may dictate, that securities sold short be returned to the lender on short notice, and the Fund may have to buy the securities sold short at an unfavorable price. If this occurs, any anticipated gain to the Fund may be reduced or eliminated or the short sale may result in a loss. The Fund’s losses are potentially unlimited in a short sale transaction. 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.

Commodity Risk. Exposure to commodities, commodity-related securities and 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.

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.

High Portfolio Turnover Risk. The Fund may 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.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

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.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class R2 Shares has varied from year to year for the past five calendar years. The table shows the average annual total returns for the past one year, five years and life of the Fund. The table compares that performance to the MSCI World Index (net of foreign withholding taxes), the Bloomberg Barclays Global Aggregate Index — Unhedged USD (new benchmark), the Bloomberg Barclays U.S. Aggregate Index (old benchmark), the Global Allocation Composite Benchmark, comprised of 60% MSCI World Index (net of foreign withholding taxes) and 40% Bloomberg Barclays Global Aggregate Index — Unhedged USD, and the Lipper Flexible Portfolio Funds Index. The Lipper index is based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other indexes, the Lipper index includes the fees and expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will performance in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your tax situation and may differ from those shown. The after-tax returns shown are not relevant to investors who hold their shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

[1] "Remainder of Other Expenses" has been calculated based on the actual other expenses incurred in the most recent fiscal year, except that these expenses have been adjusted to reflect the combination of sub-transfer agency expenses into "Shareholder Service Fees" effective 4/3/17.

[2] The Fund's adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, and extraordinary expenses) exceed 1.28% of the average daily net assets of Class R2 Shares. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund's adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund's investment in such money market funds. These waivers are in effect through 2/28/18, at which time the adviser and/or its affiliates will determine whether to renew or revise them.

[1] Effective November 30, 2016, the Fund's benchmark changed from the Bloomberg Barclays U.S. Aggregate Index to the Bloomberg Barclays Global Aggregate Index – Unhedged USD. The Fund's Board approved the change from the Bloomberg Barclays U.S. Aggregate Index to the Bloomberg Barclays Global Aggregate Index – Unhedged USD after determining that the investment universe of the Bloomberg Barclays Global Aggregate Index – Unhedged USD better reflects the investment universe of the Fund's investment strategies than the Bloomberg Barclays U.S. Aggregate Index.

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. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 64% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund has significant flexibility to invest in a broad range of equity, fixed income and alternative asset classes in the U.S. and other markets throughout the world, both developed and emerging. J.P. Morgan Investment Management Inc. (JPMIM or adviser) uses a flexible asset allocation approach in constructing the Fund’s portfolio. Under normal circumstances, the Fund will invest at least 40% of its total assets in countries other than the United States (Non-U.S. Countries) unless the adviser determines, in its sole discretion, that conditions are not favorable. If the adviser determines that conditions are not favorable, the Fund may invest under 40% of its total assets in Non-U.S. Countries provided that the Fund will not invest less than 30% of its total assets in Non-U.S. Countries under normal circumstances except for temporary defensive purposes. In managing the Fund, the adviser will invest in issuers in at least three countries other than the U.S. under normal circumstances. The Fund will invest across the full range of asset classes. Ranges for broad asset classes are:

Global Equity	10-90	%
Global Fixed Income	10-90	%
Alternatives	0-60	%
Cash and Cash Equivalents	0-80	%

The Fund’s equity investments may include common stock, preferred stock, exchange traded funds (ETFs), convertible securities, depositary receipts, warrants to buy common stocks, master limited partnerships (MLPs), and J.P. Morgan Funds. The Fund is generally unconstrained by any particular capitalization with regard to its equity investments.

The Fund’s fixed income investments may include bank obligations, convertible securities, U.S. government securities (including agencies and instrumentalities), mortgage-backed and mortgage-related securities (which may include securities that are issued by non-governmental entities), domestic and foreign corporate bonds, high yield securities (junk bonds), loan assignments and participations (Loans), debt obligations issued or guaranteed by a foreign sovereign government or its agencies, authorities or political subdivisions, floating rate securities, inflation-indexed bonds, inflation-linked securities such as Treasury Inflation Protected Securities (TIPS), J.P. Morgan Funds, and ETFs. The Fund is generally unconstrained with regard to the duration of its fixed income investments.

The Fund’s alternative investments include securities that are not a part of the Fund’s global equity or global fixed income investments. These investments may include individual securities (such as convertible securities, inflation-sensitive securities and preferred stock), J.P. Morgan Funds, ETFs, exchange traded notes (ETNs) and exchange traded commodities (ETCs). The investments in this asset class may give the Fund exposure to: market neutral strategies, long/short strategies, real estate (including real estate investment trusts (REITS)), currencies and commodities.

The Fund may invest in ETFs in order to gain exposure to particular asset classes. The Fund expects that, to the extent it invests in ETFs, it will primarily invest in passively managed ETFs. A passively managed ETF is a registered investment company that seeks to track the performance of a particular market index or security. These indexes include not only broad-based market indexes but more specific indexes as well, including those relating to particular sectors, markets, regions, industries or factors.

In addition to direct investments in securities, derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may also be used as substitutes for securities in which the Fund can invest. For example, in implementing equity market neutral strategies and macro based strategies, the Fund may use a total return swap to establish both long and short positions in order to gain the desired exposure rather than physically purchasing and selling short each instrument. The Fund may use futures contracts, options, forwards, and swaps to more effectively gain targeted equity and fixed income exposure from its cash positions, to hedge investments, for risk management and to attempt to increase the Fund’s gain. The Fund may use futures contracts, forward contracts, options (including options on interest rate futures contracts and interest rate swaps), swaps, and credit default swaps to help manage duration, sector and yield curve exposure and credit and spread volatility. The Fund may utilize exchange traded futures contracts for cash management and to gain exposure to equities pending investment in individual securities. To the extent that the Fund does not utilize underlying funds to gain exposure to commodities, it may utilize commodity linked derivatives or commodity swaps to gain exposure to commodities.

The Fund may invest in securities denominated in any currency. The Fund may utilize forward currency transactions to hedge exposure to non-dollar investments back to the U.S. dollar.

As part of the underlying strategies, the Fund may enter into short sales. In short selling transactions, the Fund sells a security it does not own in anticipation of a decline in the market value of the security. To complete the transaction, the Fund must borrow the security to make delivery to the buyer. The Fund is obligated to replace the security borrowed by purchasing it subsequently at the market price at the time of replacement.

The Fund will likely engage in active and frequent trading.

Investment Process: As attractive investments across asset classes and strategies arise, the adviser attempts to capture these opportunities and has wide latitude to allocate the Fund’s assets among strategies and asset classes. The adviser establishes the strategic and tactical allocation for the Fund and makes decisions concerning strategies, sectors, and overall portfolio construction. The adviser develops its investment insights through the combination of top-down macro views, together with the bottom-up views of the separate asset class specialists within J.P. Morgan Asset Management globally.

In buying and selling investments for the Fund, the adviser employs a continuous four-step process: (1) making asset allocation decisions based on JPMIM’s assessment of the intermediate term (6–18 months) market outlook; (2) constructing the portfolio after considering the Fund’s risk and return target, by determining the weightings of the asset classes, selecting the underlying securities, funds and other instruments; (3) analyzing the investment capabilities of the underlying portfolio managers and funds, and (4) monitoring portfolio exposures and weightings and rebalancing portfolio exposures and weightings in response to market price action and changes in JPMIM’s shorter term market outlook.

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 instruments 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

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. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

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. Securities in the Fund’s portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Interest Rate and Credit Risk. The Fund’s investments in bonds and other debt securities will change in value based on changes in interest rates. If rates rise, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate Loans and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given the historically low interest rate environment, risks associated with rising rates are heightened. The Fund’s investments are subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Foreign Securities, Emerging Markets, and Currency Risk. The Fund may invest all of its assets in securities denominated in foreign currencies. Investments in foreign currencies, 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, sanctions or other measures by the United States or other governments, 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 or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. 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. These risks are magnified in countries in “emerging markets.” Emerging Market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers. While the Fund may engage in various strategies to hedge against currency risk, it is not required to do so.

Derivatives Risk. Derivatives, including futures contracts, options, forwards, swaps and commodity linked derivatives, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including the credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate 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.

High Yield Securities and Loan Risk. The Fund invests in instruments including junk bonds, Loans and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and may be subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties and potential illiquidity. Such investments are subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, extended settlement periods, liquidity risks, prepayment risks, potentially less protections under the federal securities laws and lack of publicly available information. High yield securities and Loans that are deemed to be liquid at the time of purchase may become illiquid. No active trading market may exist for some instruments and certain investments may be subject to restrictions on resale. In addition, the settlement period for Loans is uncertain as there is no standardized settlement schedule applicable to such investments. The inability to dispose of the Fund’s securities and other investments in a timely fashion could result in losses to the Fund. Because some instruments may have a more limited secondary market, liquidity risk is more pronounced for the Fund than for funds that invest primarily in other types of fixed income instruments or equity securities. When Loans and other instruments are prepaid, the Fund may have to reinvest in instruments with a lower yield or fail to recover additional amounts (i.e., premiums) paid for these instruments, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. Certain Loans may not be considered securities under the federal securities laws and, therefore, investments in such Loans may not be subject to certain protections under those laws. In addition, the adviser may not have access to material non-public information to which other investors may have access.

Mortgage-Related and Other Mortgage-Backed Securities Risk. The Fund may invest in both residential or commercial mortgage-related and mortgage-backed securities that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. In periods of rising interest rates, the Fund may be subject to extension risk, and may receive principal later than expected. As a result, in periods of rising interest rates, the Fund may exhibit additional volatility. During periods of difficult or frozen credit markets, significant changes in interest rates or deteriorating economic conditions, such securities may decline in value, face valuation difficulties, become more volatile and/or become 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 credit-worthiness 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.

MLP Risk. MLPs may trade infrequently and in limited volume and they may be subject to more abrupt or erratic price movements than securities of larger or more broadly-based companies. MLPs are subject to “commodity risks” as well as the risks associated with the specific industry or industries in which the partnership invests. In addition, the managing general partner of an MLP may receive an incentive allocation based on increases in the amount and growth of cash distributions to investors in the MLP. This method of compensation may create an incentive for the managing general partner to make investments that are riskier or more speculative than would be the case in the absence of such compensation arrangements. Certain MLPs may operate in, or have exposure to, the energy sector. The energy sector can be significantly affected by changes in the prices and supplies of oil and other energy fuels, energy conservation, the success of exploration projects, and tax and other government regulations, policies of the Organization of Petroleum Exporting Countries (OPEC) and relationships among OPEC members and between OPEC and oil importing nations.

Investment Company and Pooled Investment Vehicle Risk. The Fund may invest in shares of other investment companies, including closed-end funds, ETFs and other pooled investment vehicles, including those holding commodities, currencies or commodity futures. Shareholders bear both their proportionate share of the Fund’s expenses and similar expenses of the investment company or pooled investment vehicle. ETFs and other investment companies or pooled investment vehicles that invest in commodities or currencies are subject to the risks associated with direct investments in commodities or currencies. The price and movement of an ETF, closed-end fund or pooled investment vehicle designed to track an index may not track the index and may result in a loss. In addition, closed-end funds that trade on an exchange often trade at a price below their net asset value (also known as a discount). Certain ETFs, closed-end funds or pooled investment vehicles traded on exchanges may be thinly traded and experience large spreads between the “ask” price quoted by a seller and the “bid” price offered by a buyer. There may be no active market for shares of certain closed-end funds or pooled investment vehicles (especially those not traded on exchanges) and such shares may be highly illiquid. 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.

Government Securities Risk. The Fund invests in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. 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 may not have the funds to meet their payment obligations in the future.

Inflation-Linked Securities Risk. Unlike conventional bonds, the principal or interest of inflation-linked securities such as TIPS is adjusted periodically to a specified rate of inflation (e.g., Consumer Price Index for all Urban Consumers (CPI-U)). There can be no assurance that the inflation index used will accurately measure the real rate of inflation. These securities may lose value in the event that the actual rate of inflation is different than the rate of the inflation index.

ETN Risk. Generally, ETNs are structured as senior, unsecured notes in which an issuer such as a bank agrees to pay a return based on the target commodity index less any fees. ETNs are synthetic instruments that allow individual investors to have access to derivatives linked to commodities and assets such as oil, Currencies and foreign stock indexes. ETNs combine certain aspects of bond and ETFs. Similar to ETFs, ETNs are traded on a major exchange (e.g., the New York Stock Exchange) during normal trading hours. However, investors can also hold the ETN until maturity. At maturity, the issuer pays to the investor a cash amount equal to the principal amount, subject to the day’s index factor. ETN returns are based upon the performance of a market index minus applicable fees. The value of an ETN may be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying commodities markets, changes in the applicable interest rates, changes in the issuer’s credit rating and economic, legal, political or geographic events that affect the referenced commodity. The value of the ETN may drop due to a downgrade in the issuer’s credit rating, even if the underlying index remains unchanged. Investments in ETNs are subject to the risks facing income securities in general including the risk that a counterparty will fail to make payments when due or default. In addition, investors in ETNs generally have no right with respect to the instruments underlying the index or any right to receive delivery of the instruments underlying the index.

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 the short sale and the date on which the fund purchases the security to replace the borrowed security. In addition, a lender may request, or market conditions may dictate, that securities sold short be returned to the lender on short notice, and the Fund may have to buy the securities sold short at an unfavorable price. If this occurs, any anticipated gain to the Fund may be reduced or eliminated or the short sale may result in a loss. The Fund’s losses are potentially unlimited in a short sale transaction. 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.

Commodity Risk. Exposure to commodities, commodity-related securities and 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.

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.

High Portfolio Turnover Risk. The Fund may 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.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

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.

R6 Shares | JPMorgan Systematic Alpha Fund

JPMorgan Systematic Alpha Fund

Class/Ticker: R6/JALPX

What is the goal of the Fund?

The Fund seeks to provide total return.

Fees and Expenses of the Fund

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

“Acquired Fund Fees and Expenses” are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies, including affiliated money market funds, other mutual funds, exchange-traded funds and business development companies. The impact of Acquired Fund Fees and Expenses is included in the total returns of the Fund. Acquired Fund Fees and Expenses are not direct costs of the Fund, are not used to calculate the Fund’s net asset value per share and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus.

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. The Fund’s portfolio turnover rate was 151% of the average value of its portfolio.

What are the Fund’s main investment strategies?

J.P. Morgan Investment Management Inc., the Fund’s investment adviser (the adviser), believes that it has identified a set of return sources present in markets, such as equities, fixed income, convertible bonds, currencies and commodities, that result from, among other things, assuming a particular risk or taking advantage of a behavioral bias (each a “return factor”). For example, an investor may expect a higher return over time when investing in small cap stocks compared to large cap stocks due to the additional risks often posed by small cap stocks. The adviser may allocate assets to this “small cap return factor” by employing a strategy that purchases small cap stocks and shorts large cap stocks in an attempt to capture the risk premium typically associated with investing in small cap companies relative to large cap companies. Additionally, the adviser may gain exposure to a “momentum return factor” by employing a strategy that buys stocks with strong positive price momentum and shorts stocks with strong negative price momentum. This strategy would seek to exploit a behavioral bias present in the market, in which investors tend to purchase stocks that have recently performed well, thereby helping to contribute to continued positive price movement, and sell stocks that have recently performed poorly, thereby helping to contribute to continued negative price movement. Under normal market conditions, the Fund seeks to achieve its investment objective by employing alternative investment strategies to access certain of these return factors. The return factors the adviser will seek to access have historically presented a low correlation to each other and to traditional asset classes and have unique risk and return profiles, and by employing this return factor based approach, the Fund seeks to provide total returns over time while maintaining a relatively low correlation with traditional asset classes.

The adviser will use a proprietary investment model to allocate assets to a subset of return factors. The return factors identified by the adviser include equity based return factors, fixed income based return factors, convertible bond based return factors, currency based return factors and commodity based return factors. The alternative investment strategies the Fund may employ to gain exposure to return factors include equity market neutral, event driven, convertible arbitrage and macro based strategies. “Systematic” in the Fund’s name refers to the adviser’s model-driven investment process and “Alpha” in the Fund’s name refers to the adviser’s attempt to identify individual return factors that are expected to contribute to the Fund’s total return.

The instruments in which the Fund may invest, either directly or through the use of derivatives, include equity securities, debt securities, convertible securities, commodities and currencies. The amount that may be invested in any one instrument will vary and generally depends on the investment strategies employed by the adviser at that point in 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, and may invest in below investment grade instruments (junk bonds). The Fund may have both long and short exposure to these instruments.

The adviser will make use of derivatives, including swaps, futures and forwards, in implementing its strategies. Under normal market conditions, the adviser currently expects that a significant portion of the Fund’s exposure will be attained through the use of derivatives, in addition to its exposure through direct investments. Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, will primarily be used as an efficient means of implementing a particular strategy in order to gain exposure to a desired return factor. For example, in implementing equity market neutral strategies and macro based strategies, the Fund may use a total return swap to establish both long and short positions in order to gain the desired exposure rather than physically purchasing and selling short each instrument. Derivatives may also be used to increase gain, to effectively gain targeted equity exposure from its cash positions, to hedge various investments and/or for risk management. 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, and other short-term investments, including commercial paper, time deposits and money market funds.

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 contribution to the Fund’s overall volatility. In allocating assets, the adviser seeks to approximately equal risk weight to the individual return factors over the long term, although the exposure to individual return factors will vary based on, among other things, the opportunity the adviser sees in each individual return factor.

The Fund will gain exposure to commodity markets by investing up to 15% of its total assets in the Systematic Alpha Fund CS 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 related investments, including derivative instruments 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 may hold instruments described elsewhere in this prospectus that are not commodity related and 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 return factor based approach will achieve any particular level of return or will, in fact, reduce volatility or potential loss. The Fund’s returns over time or during any period may be negative and the Fund may underperform the overall security markets over time or during any particular period.

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 instruments 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

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. Securities in the Fund’s portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

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”.

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 decreases in value.

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 Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and vulnerable to economic, market and industry changes than securities of larger more established companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

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, sanctions or other measures by the United States or other governments, 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 or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. 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. These risks are magnified in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

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 declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given the historically low interest rate environment, risks associated with rising rates are heightened. The Fund’s investments are subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

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 economic changes, valuation difficulties, and potential illiquidity. 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 securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. 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 will provide financial support. Therefore, U.S. government related organizations 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.

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 impacted by that currency loses value because that currency is worth less in U.S. dollars. Currency exchange rates may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates. 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. Although the Fund may attempt to hedge its currency exposure into the U.S. dollar, it may not be successful in reducing 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.

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, 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.

Under normal market conditions, the adviser currently expects that a significant portion of the Fund’s exposure will be attained through the use of derivatives. Investing in derivatives will result in a form of leverage, which may be significant. 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 may also be subject to risks related to swap agreements, including total return swaps. Total return swaps are contracts in which one party agrees to make periodic payments based on the change in market value of the underlying assets, which may include a specified security, basket of securities or securities indices during the specified period, in return for periodic payments based on a fixed or variable interest rate or the total return from other underlying assets. Total return swaps may be used to obtain exposure to a security or market without owning or taking physical custody of such security or market and may be used 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’s returns are reduced or its losses increased by the costs associated with the swap, which may be significant. In addition, there is the risk that the swap may be terminated by the Fund or the counterparty in accordance with its terms or as a result of regulatory changes. If the swap were to terminate, the Fund may be unable to employ its investment strategy and may suffer losses. The Fund will segregate or earmark liquid assets at its custodian bank in an amount sufficient to cover its obligations under swap agreements.

Subsidiary and Tax 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 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. 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.

The Fund has not received a private letter ruling from the Internal Revenue Service (the IRS) with respect to income derived from its investment in the Subsidiary. The Fund relies on the reasoning of private letter rulings from the IRS to other taxpayers with respect to its investment in the Subsidiary.

There can be no assurance that the IRS will not change its position that income derived from commodity-linked notes and wholly-owned subsidiaries is qualifying income. The tax treatment of commodity-linked notes, other commodity-linked derivatives and the Fund’s investments in the Subsidiary may be adversely affected by future legislation, Treasury regulations and/or guidance issued by the IRS that could affect whether income from such investments is qualifying income under Subchapter M of the Internal Revenue Code of 1986, as amended, or otherwise alter the character, timing and/or amount of the Fund’s taxable income or any gains and distributions made by the Fund.

Model and Data Risk. Given the complexity of the investments and strategies of the Fund, the adviser will make use of quantitative models and information and data supplied by third parties to, among other things, help determine the portfolio’s asset allocation weightings and construct sets of transactions and investments. To the extent the models used by the adviser or the information and data supplied by third parties are incorrect or incomplete, the decisions made by the adviser in reliance thereon will expose the Fund to potential risks and could lead to the Fund incurring losses on its investments.

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.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

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.

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

J.P. Morgan Investment Management Inc., the Fund’s investment adviser (the adviser), believes that it has identified a set of return sources present in markets, such as equities, fixed income, convertible bonds, currencies and commodities, that result from, among other things, assuming a particular risk or taking advantage of a behavioral bias (each a “return factor”). For example, an investor may expect a higher return over time when investing in small cap stocks compared to large cap stocks due to the additional risks often posed by small cap stocks. The adviser may allocate assets to this “small cap return factor” by employing a strategy that purchases small cap stocks and shorts large cap stocks in an attempt to capture the risk premium typically associated with investing in small cap companies relative to large cap companies. Additionally, the adviser may gain exposure to a “momentum return factor” by employing a strategy that buys stocks with strong positive price momentum and shorts stocks with strong negative price momentum. This strategy would seek to exploit a behavioral bias present in the market, in which investors tend to purchase stocks that have recently performed well, thereby helping to contribute to continued positive price movement, and sell stocks that have recently performed poorly, thereby helping to contribute to continued negative price movement. Under normal market conditions, the Fund seeks to achieve its investment objective by employing alternative investment strategies to access certain of these return factors. The return factors the adviser will seek to access have historically presented a low correlation to each other and to traditional asset classes and have unique risk and return profiles, and by employing this return factor based approach, the Fund seeks to provide total returns over time while maintaining a relatively low correlation with traditional asset classes.

The adviser will use a proprietary investment model to allocate assets to a subset of return factors. The return factors identified by the adviser include equity based return factors, fixed income based return factors, convertible bond based return factors, currency based return factors and commodity based return factors. The alternative investment strategies the Fund may employ to gain exposure to return factors include equity market neutral, event driven, convertible arbitrage and macro based strategies. “Systematic” in the Fund’s name refers to the adviser’s model-driven investment process and “Alpha” in the Fund’s name refers to the adviser’s attempt to identify individual return factors that are expected to contribute to the Fund’s total return.

The instruments in which the Fund may invest, either directly or through the use of derivatives, include equity securities, debt securities, convertible securities, commodities and currencies. The amount that may be invested in any one instrument will vary and generally depends on the investment strategies employed by the adviser at that point in 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, and may invest in below investment grade instruments (junk bonds). The Fund may have both long and short exposure to these instruments.

The adviser will make use of derivatives, including swaps, futures and forwards, in implementing its strategies. Under normal market conditions, the adviser currently expects that a significant portion of the Fund’s exposure will be attained through the use of derivatives, in addition to its exposure through direct investments. Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, will primarily be used as an efficient means of implementing a particular strategy in order to gain exposure to a desired return factor. For example, in implementing equity market neutral strategies and macro based strategies, the Fund may use a total return swap to establish both long and short positions in order to gain the desired exposure rather than physically purchasing and selling short each instrument. Derivatives may also be used to increase gain, to effectively gain targeted equity exposure from its cash positions, to hedge various investments and/or for risk management. 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, and other short-term investments, including commercial paper, time deposits and money market funds.

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 contribution to the Fund’s overall volatility. In allocating assets, the adviser seeks to approximately equal risk weight to the individual return factors over the long term, although the exposure to individual return factors will vary based on, among other things, the opportunity the adviser sees in each individual return factor.

The Fund will gain exposure to commodity markets by investing up to 15% of its total assets in the Systematic Alpha Fund CS 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 related investments, including derivative instruments 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 may hold instruments described elsewhere in this prospectus that are not commodity related and 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 return factor based approach will achieve any particular level of return or will, in fact, reduce volatility or potential loss. The Fund’s returns over time or during any period may be negative and the Fund may underperform the overall security markets over time or during any particular period.

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 instruments 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

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. Securities in the Fund’s portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

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”.

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 decreases in value.

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 Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and vulnerable to economic, market and industry changes than securities of larger more established companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

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, sanctions or other measures by the United States or other governments, 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 or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. 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. These risks are magnified in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

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 declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given the historically low interest rate environment, risks associated with rising rates are heightened. The Fund’s investments are subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

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 economic changes, valuation difficulties, and potential illiquidity. 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 securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. 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 will provide financial support. Therefore, U.S. government related organizations 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.

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 impacted by that currency loses value because that currency is worth less in U.S. dollars. Currency exchange rates may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates. 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. Although the Fund may attempt to hedge its currency exposure into the U.S. dollar, it may not be successful in reducing 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.

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, 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.

Under normal market conditions, the adviser currently expects that a significant portion of the Fund’s exposure will be attained through the use of derivatives. Investing in derivatives will result in a form of leverage, which may be significant. 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 may also be subject to risks related to swap agreements, including total return swaps. Total return swaps are contracts in which one party agrees to make periodic payments based on the change in market value of the underlying assets, which may include a specified security, basket of securities or securities indices during the specified period, in return for periodic payments based on a fixed or variable interest rate or the total return from other underlying assets. Total return swaps may be used to obtain exposure to a security or market without owning or taking physical custody of such security or market and may be used 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’s returns are reduced or its losses increased by the costs associated with the swap, which may be significant. In addition, there is the risk that the swap may be terminated by the Fund or the counterparty in accordance with its terms or as a result of regulatory changes. If the swap were to terminate, the Fund may be unable to employ its investment strategy and may suffer losses. The Fund will segregate or earmark liquid assets at its custodian bank in an amount sufficient to cover its obligations under swap agreements.

Subsidiary and Tax 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 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. 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.

The Fund has not received a private letter ruling from the Internal Revenue Service (the IRS) with respect to income derived from its investment in the Subsidiary. The Fund relies on the reasoning of private letter rulings from the IRS to other taxpayers with respect to its investment in the Subsidiary.

There can be no assurance that the IRS will not change its position that income derived from commodity-linked notes and wholly-owned subsidiaries is qualifying income. The tax treatment of commodity-linked notes, other commodity-linked derivatives and the Fund’s investments in the Subsidiary may be adversely affected by future legislation, Treasury regulations and/or guidance issued by the IRS that could affect whether income from such investments is qualifying income under Subchapter M of the Internal Revenue Code of 1986, as amended, or otherwise alter the character, timing and/or amount of the Fund’s taxable income or any gains and distributions made by the Fund.

Model and Data Risk. Given the complexity of the investments and strategies of the Fund, the adviser will make use of quantitative models and information and data supplied by third parties to, among other things, help determine the portfolio’s asset allocation weightings and construct sets of transactions and investments. To the extent the models used by the adviser or the information and data supplied by third parties are incorrect or incomplete, the decisions made by the adviser in reliance thereon will expose the Fund to potential risks and could lead to the Fund incurring losses on its investments.

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.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

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.

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. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 189% of the average value of its portfolio.

What are the Fund’s main investment strategies?

The Fund invests primarily in debt investments that it believes have the potential to provide total return from countries whose economies or bond markets are less developed (emerging markets). The Fund's adviser, J.P. Morgan Investment Management Inc. (JPMIM or the adviser) uses a flexible asset allocation approach to invest the Fund opportunistically among different emerging market sectors and instruments. Under normal circumstances, the Fund invests at least 80% of its Assets in emerging market debt investments. "Emerging market debt investments" are securities and instruments of issuers located in or tied economically to emerging markets. "Assets" means net assets, plus the amount of borrowings for investment purposes. Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. Emerging markets currently include most countries in the world except Australia, Canada, Japan, New Zealand, the U.S., the United Kingdom, and most of the countries of western Europe and Hong Kong. A security will be deemed to be tied economically to emerging markets if: (1) the issuer is organized under the laws of, or has a principal place of business in an emerging market; or (2) the principal listing of the issuer's securities is in a market that is in an emerging market; or (3) the issuer derives at least 50% of its total revenues or profits from goods that are produced or sold, investments made, or services performed in an emerging market; or (4) the issuer has at least 50% of its assets located in an emerging market.

The Fund is unconstrained and may invest in a broad array of emerging market debt securities and sectors including corporate debt and sovereign debt. These securities may be denominated in U.S. and other developed market currencies as well as emerging markets currencies (local currencies). Sovereign debt securities are securities that are issued or guaranteed by foreign sovereign governments or their agencies, authorities or political subdivisions or instrumentalities, and supranational agencies. The Fund may invest in debt securities issued or guaranteed by foreign corporations and foreign financial institutions.

The Fund's securities may be of any maturity, duration or quality. The Fund does not have any minimum quality rating requirement and may invest without limit in securities that are rated below investment grade (commonly known as junk bonds) or the unrated equivalent. As part of its principal investment strategies, the Fund may invest in foreign municipal securities, including foreign provincial securities, fixed and floating or variable rate instruments, inflation-linked securities, corporate debt securities, private placements, zero-coupon securities and loan participation notes. The Fund may also invest in structured investments such as credit linked notes (CLNs) involving U.S. or non-U.S. counterparties for which the reference instrument is an emerging markets debt instrument denominated in an emerging markets currency. CLNs are typically structured as a limited purpose trust or other vehicle that, in turn, invests in a derivative or basket of derivative instruments, such as credit default swaps, interest rate swaps and/or other securities, in order to provide exposure to emerging markets.

Derivatives are instruments that have a value based on another instrument, exchange rate or index. In addition to direct investments in securities, the Fund will use derivatives as a substitute for securities in which the Fund can invest. The Fund may use derivatives including foreign currency transactions such as currency forwards including non-deliverable forwards, futures contracts, options, swaps such as interest rate swaps and credit default swaps, and securities with embedded derivatives such as CLNs. The Fund may use swaps structured as credit default swaps related to individual securities or indexes of securities to gain or to limit exposure to securities, to mitigate risk exposure and to manage cash flow needs. The Fund may also use foreign currency transactions, futures contracts, options, credit default swaps and currency options to help manage duration, sector and yield curve exposure and credit and spread volatility and to establish or adjust exposure to particular foreign securities, markets or currencies. The Fund also may use derivatives to hedge an investment in one currency back to another currency, to increase income and gain to the Fund, and/or as part of its risk management process by establishing or adjusting exposure to particular foreign securities, markets or currencies.

The Fund may invest in registered investment companies including J.P. Morgan money market funds, securities issued by the U.S. government and its agencies, or other investments to maintain asset coverage for the Fund's derivative positions and for cash management purposes.

The adviser buys and sells securities and investments for the Fund based on its view of individual securities and market sectors, combining macro-economic research with bottom up fundamental country and credit analysis. The adviser analyzes rates and foreign exchanges separately using a quantitative assessment with a qualitative overlay. Taking a long-term approach, the adviser looks for individual fixed income investments that it believes will perform well over market cycles. The adviser is value oriented and makes decisions to purchase and sell individual securities and instruments after performing a risk/reward analysis that includes an evaluation of interest rate risk, currency risk, credit risk, duration, liquidity and the complex legal and technical structure of the transaction.

The Fund is non-diversified.

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 instruments 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund's performance and ability to meet its investment objective.

Foreign Securities and Emerging Markets Risk. Investments in foreign issuers and foreign securities are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, sanctions or other measures by the United States or other governments, 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 or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. 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. These risks are magnified in countries in "emerging markets." Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

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. Securities in the Fund's portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

European Market Risk. The Fund's performance will be affected by political, social and economic conditions in Europe, such as growth of the economic output (the gross national product), the rate of inflation, the rate at which capital is reinvested into European economies, the success of governmental actions to reduce budget deficits, the resource self-sufficiency of European countries and interest and monetary exchange rates between European countries. European financial markets may experience volatility due to concerns about high government debt levels, credit rating downgrades, rising unemployment, the future of the euro as a common currency, possible restructuring of government debt and other government measures responding to those concerns, and fiscal and monetary controls imposed on member countries of the European Union. The risk of investing in Europe may be heightened due to the referendum in which the United Kingdom voted to exit the European Union. In addition, if one or more countries were to exit the European Union or abandon the use of the euro as a currency, the value of investments tied to those countries or the euro could decline significantly and unpredictably.

Sovereign Debt Risk. Sovereign debt investments are subject to the risk of payment delays or defaults, due, for example, to cash flow problems, insufficient foreign currency reserves, political considerations, large debt positions relative to the country's economy or failure to implement economic reforms. There is no legal or bankruptcy process for collecting sovereign debt.

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 impacted by that currency loses value because that currency is worth less in U.S. dollars. Currency exchange rates may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates. 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. Although the Fund may attempt to hedge its currency exposure into the U.S. dollar, it may not be successful in reducing 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.

Interest Rate Risk. The Fund's investments in bonds and other debt securities will change in value based on changes in interest rates. If rates rise, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given the historically low interest rate environment, risks associated with rising rates are heightened.

Credit Risk. The Fund's investments are subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund's investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund's securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer's securities.

Derivatives Risk. Derivatives, including currency forwards, interest rate swaps and currency options, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be particularly 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 expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). 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. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the currency, security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation. Certain of the Fund's transactions in foreign currency derivatives and other derivatives could also affect the amount, timing and character of distributions to shareholders which may result in the Fund realizing more short-term capital gain and ordinary income subject to tax at ordinary income tax rates than it would if it did not engage in such transactions, which may adversely impact the Fund's after-tax returns.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares' values may fluctuate in response to events affecting that industry or sector.

High Yield Securities Risk. The Fund may invest in securities that are obligations of companies that are highly leveraged, less creditworthy or financially distressed. These investments (known as junk bonds) are considered to be speculative and are subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties and potential illiquidity.

Foreign Municipal Securities Risk. The risk of a foreign municipal security generally depends on the financial and credit status of the issuer, which in turn will depend on the local economic, regulatory, political and other factors and conditions. Changes in a municipality's financial health may make it difficult for the municipality to make interest and principal payments when due. This could decrease the Fund's income or hurt the ability to preserve capital and liquidity. Under some circumstances, municipal securities might not pay interest unless the applicable legislature or municipality authorizes money for that purpose. In addition, the issuer of the obligations may be unable or unwilling to make interest and principal payments when due. These securities are also subject to foreign and emerging markets risks based on the location of the issuer.

Privately Placed Securities Risk. Privately placed securities generally are less liquid than publicly traded securities and the Fund may not always be able to sell such securities without experiencing delays in finding buyers or reducing the sale price for such securities. The disposition of some of the securities held by the Fund may be restricted under federal securities laws. As a result, the Fund may not be able to dispose of such investments at a time when, or at a price at which, it desires to do so and may have to bear expenses of registering these securities, if necessary. These securities may also be difficult to value.

CLN Risk. CLNs are synthetic instruments that are subject to the counterparty risk described above under "Credit Risk." In the event of a default, the Fund does not have a right in the underlying reference debt obligation. Generally, payments under the CLN are conditioned on the CLN's receipt of payments from, and the CLN's potential obligations, to the counterparties to the derivative instruments and other securities in which the CLN invests. If a default were to occur, the stream of payments may stop and the CLN would be obligated to pay the counterparty the par value (or other agreed upon value) of the referenced debt obligation. This, in turn, would reduce the amount of income and principal that the Fund would receive as an investor in the CLN.

Zero-Coupon, Pay-In-Kind and Deferred Payment Securities Risk. The market value of a zero-coupon, pay-in-kind or deferred payment security is generally more volatile than the market value of, and is more likely to respond to a greater degree to changes in interest rates than, other fixed income securities with similar maturities and credit quality that pay interest periodically. In addition, federal income tax law requires that the holder of a zero-coupon security accrue a portion of the discount at which the security was purchased as taxable income each year. The Fund may consequently have to dispose of portfolio securities under disadvantageous circumstances to generate cash to satisfy its requirement as a regulated investment company to distribute all of its net income.

Inflation-Linked Security Risk. Inflation-linked emerging markets debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of an inflation-linked security tends to decline when real interest rates increase. Unlike conventional bonds, the principal and interest payments of inflation-linked securities may be adjusted periodically to a specified rate of inflation. There can be no assurance that the inflation index used will accurately measure the real rate of inflation in a particular emerging market or in the emerging markets in which the Fund invests or in the United States. These securities may lose value in the event that the actual rate of inflation is different than the rate of the inflation index. In addition, changes in foreign exchange rates may negate the impact of any adjustments to interest rates payable on the securities for non-U.S. dollar denominated inflation-linked securities.

Investment Company Risk. Shareholders bear both their proportionate share of the Fund's expenses and similar expenses of another investment company in which the Fund may invest.

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.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund's performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Non-Diversified Fund Risk. Since the Fund is non-diversified, it may invest a greater percentage of its assets in a particular issuer or group of issuers than a diversified fund would. This increased investment in fewer issuers may result in the Fund's shares being more sensitive to economics results of those issuing the securities.

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.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how performance of the Fund’s Select Class Shares varied from year to year over the past four calendar years. The table shows the average annual total returns over the past one year and life of the Fund. The table compares that performance to the J.P. Morgan Emerging Markets Bond Index (EMBI) Global Diversified, the J.P. Morgan Government Bond Index-Emerging Markets (GBI-EM) Global Diversified, the Emerging Markets Strategic Debt Composite Benchmark (a composite benchmark of the equally weighted average of J.P. Morgan EMBI Global Diversified, J.P. Morgan GBI-EM Global Diversified and J.P. Morgan Corporate Emerging Markets Bond Index (CEMBI) Broad Diversified) and the Lipper Emerging Markets Local Currency Debt Funds Index. The Lipper index is based on the total return of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other indexes, the Lipper index includes the fees and expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

Effective September 30, 2016 (the "Effective Date"), some of the Fund's investment strategies changed. The Fund's past performance would have been different if the Fund were managed using the current strategies. On the Effective Date, the Fund's broad based securities market index changed from the J.P. Morgan GBI-EM Global Diversified to the J.P. Morgan Emerging Markets Bond Index (EMBI) Global Diversified to reflect the change in the Fund's investment strategies.

The Fund invests primarily in debt investments that it believes have the potential to provide total return from countries whose economies or bond markets are less developed (emerging markets). The Fund's adviser, J.P. Morgan Investment Management Inc. (JPMIM or the adviser) uses a flexible asset allocation approach to invest the Fund opportunistically among different emerging market sectors and instruments. Under normal circumstances, the Fund invests at least 80% of its Assets in emerging market debt investments. "Emerging market debt investments" are securities and instruments of issuers located in or tied economically to emerging markets. "Assets" means net assets, plus the amount of borrowings for investment purposes. Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. Emerging markets currently include most countries in the world except Australia, Canada, Japan, New Zealand, the U.S., the United Kingdom, and most of the countries of western Europe and Hong Kong. A security will be deemed to be tied economically to emerging markets if: (1) the issuer is organized under the laws of, or has a principal place of business in an emerging market; or (2) the principal listing of the issuer's securities is in a market that is in an emerging market; or (3) the issuer derives at least 50% of its total revenues or profits from goods that are produced or sold, investments made, or services performed in an emerging market; or (4) the issuer has at least 50% of its assets located in an emerging market.

The Fund is unconstrained and may invest in a broad array of emerging market debt securities and sectors including corporate debt and sovereign debt. These securities may be denominated in U.S. and other developed market currencies as well as emerging markets currencies (local currencies). Sovereign debt securities are securities that are issued or guaranteed by foreign sovereign governments or their agencies, authorities or political subdivisions or instrumentalities, and supranational agencies. The Fund may invest in debt securities issued or guaranteed by foreign corporations and foreign financial institutions.

The Fund's securities may be of any maturity, duration or quality. The Fund does not have any minimum quality rating requirement and may invest without limit in securities that are rated below investment grade (commonly known as junk bonds) or the unrated equivalent. As part of its principal investment strategies, the Fund may invest in foreign municipal securities, including foreign provincial securities, fixed and floating or variable rate instruments, inflation-linked securities, corporate debt securities, private placements, zero-coupon securities and loan participation notes. The Fund may also invest in structured investments such as credit linked notes (CLNs) involving U.S. or non-U.S. counterparties for which the reference instrument is an emerging markets debt instrument denominated in an emerging markets currency. CLNs are typically structured as a limited purpose trust or other vehicle that, in turn, invests in a derivative or basket of derivative instruments, such as credit default swaps, interest rate swaps and/or other securities, in order to provide exposure to emerging markets.

Derivatives are instruments that have a value based on another instrument, exchange rate or index. In addition to direct investments in securities, the Fund will use derivatives as a substitute for securities in which the Fund can invest. The Fund may use derivatives including foreign currency transactions such as currency forwards including non-deliverable forwards, futures contracts, options, swaps such as interest rate swaps and credit default swaps, and securities with embedded derivatives such as CLNs. The Fund may use swaps structured as credit default swaps related to individual securities or indexes of securities to gain or to limit exposure to securities, to mitigate risk exposure and to manage cash flow needs. The Fund may also use foreign currency transactions, futures contracts, options, credit default swaps and currency options to help manage duration, sector and yield curve exposure and credit and spread volatility and to establish or adjust exposure to particular foreign securities, markets or currencies. The Fund also may use derivatives to hedge an investment in one currency back to another currency, to increase income and gain to the Fund, and/or as part of its risk management process by establishing or adjusting exposure to particular foreign securities, markets or currencies.

The Fund may invest in registered investment companies including J.P. Morgan money market funds, securities issued by the U.S. government and its agencies, or other investments to maintain asset coverage for the Fund's derivative positions and for cash management purposes.

The adviser buys and sells securities and investments for the Fund based on its view of individual securities and market sectors, combining macro-economic research with bottom up fundamental country and credit analysis. The adviser analyzes rates and foreign exchanges separately using a quantitative assessment with a qualitative overlay. Taking a long-term approach, the adviser looks for individual fixed income investments that it believes will perform well over market cycles. The adviser is value oriented and makes decisions to purchase and sell individual securities and instruments after performing a risk/reward analysis that includes an evaluation of interest rate risk, currency risk, credit risk, duration, liquidity and the complex legal and technical structure of the transaction.

The Fund is non-diversified.

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 instruments 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund's performance and ability to meet its investment objective.

Foreign Securities and Emerging Markets Risk. Investments in foreign issuers and foreign securities are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, sanctions or other measures by the United States or other governments, 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 or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. 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. These risks are magnified in countries in "emerging markets." Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

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. Securities in the Fund's portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

European Market Risk. The Fund's performance will be affected by political, social and economic conditions in Europe, such as growth of the economic output (the gross national product), the rate of inflation, the rate at which capital is reinvested into European economies, the success of governmental actions to reduce budget deficits, the resource self-sufficiency of European countries and interest and monetary exchange rates between European countries. European financial markets may experience volatility due to concerns about high government debt levels, credit rating downgrades, rising unemployment, the future of the euro as a common currency, possible restructuring of government debt and other government measures responding to those concerns, and fiscal and monetary controls imposed on member countries of the European Union. The risk of investing in Europe may be heightened due to the referendum in which the United Kingdom voted to exit the European Union. In addition, if one or more countries were to exit the European Union or abandon the use of the euro as a currency, the value of investments tied to those countries or the euro could decline significantly and unpredictably.

Sovereign Debt Risk. Sovereign debt investments are subject to the risk of payment delays or defaults, due, for example, to cash flow problems, insufficient foreign currency reserves, political considerations, large debt positions relative to the country's economy or failure to implement economic reforms. There is no legal or bankruptcy process for collecting sovereign debt.

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 impacted by that currency loses value because that currency is worth less in U.S. dollars. Currency exchange rates may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates. 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. Although the Fund may attempt to hedge its currency exposure into the U.S. dollar, it may not be successful in reducing 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.

Interest Rate Risk. The Fund's investments in bonds and other debt securities will change in value based on changes in interest rates. If rates rise, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given the historically low interest rate environment, risks associated with rising rates are heightened.

Credit Risk. The Fund's investments are subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund's investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund's securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer's securities.

Derivatives Risk. Derivatives, including currency forwards, interest rate swaps and currency options, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be particularly 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 expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). 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. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the currency, security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation. Certain of the Fund's transactions in foreign currency derivatives and other derivatives could also affect the amount, timing and character of distributions to shareholders which may result in the Fund realizing more short-term capital gain and ordinary income subject to tax at ordinary income tax rates than it would if it did not engage in such transactions, which may adversely impact the Fund's after-tax returns.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares' values may fluctuate in response to events affecting that industry or sector.

High Yield Securities Risk. The Fund may invest in securities that are obligations of companies that are highly leveraged, less creditworthy or financially distressed. These investments (known as junk bonds) are considered to be speculative and are subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties and potential illiquidity.

Foreign Municipal Securities Risk. The risk of a foreign municipal security generally depends on the financial and credit status of the issuer, which in turn will depend on the local economic, regulatory, political and other factors and conditions. Changes in a municipality's financial health may make it difficult for the municipality to make interest and principal payments when due. This could decrease the Fund's income or hurt the ability to preserve capital and liquidity. Under some circumstances, municipal securities might not pay interest unless the applicable legislature or municipality authorizes money for that purpose. In addition, the issuer of the obligations may be unable or unwilling to make interest and principal payments when due. These securities are also subject to foreign and emerging markets risks based on the location of the issuer.

Privately Placed Securities Risk. Privately placed securities generally are less liquid than publicly traded securities and the Fund may not always be able to sell such securities without experiencing delays in finding buyers or reducing the sale price for such securities. The disposition of some of the securities held by the Fund may be restricted under federal securities laws. As a result, the Fund may not be able to dispose of such investments at a time when, or at a price at which, it desires to do so and may have to bear expenses of registering these securities, if necessary. These securities may also be difficult to value.

CLN Risk. CLNs are synthetic instruments that are subject to the counterparty risk described above under "Credit Risk." In the event of a default, the Fund does not have a right in the underlying reference debt obligation. Generally, payments under the CLN are conditioned on the CLN's receipt of payments from, and the CLN's potential obligations, to the counterparties to the derivative instruments and other securities in which the CLN invests. If a default were to occur, the stream of payments may stop and the CLN would be obligated to pay the counterparty the par value (or other agreed upon value) of the referenced debt obligation. This, in turn, would reduce the amount of income and principal that the Fund would receive as an investor in the CLN.

Zero-Coupon, Pay-In-Kind and Deferred Payment Securities Risk. The market value of a zero-coupon, pay-in-kind or deferred payment security is generally more volatile than the market value of, and is more likely to respond to a greater degree to changes in interest rates than, other fixed income securities with similar maturities and credit quality that pay interest periodically. In addition, federal income tax law requires that the holder of a zero-coupon security accrue a portion of the discount at which the security was purchased as taxable income each year. The Fund may consequently have to dispose of portfolio securities under disadvantageous circumstances to generate cash to satisfy its requirement as a regulated investment company to distribute all of its net income.

Inflation-Linked Security Risk. Inflation-linked emerging markets debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of an inflation-linked security tends to decline when real interest rates increase. Unlike conventional bonds, the principal and interest payments of inflation-linked securities may be adjusted periodically to a specified rate of inflation. There can be no assurance that the inflation index used will accurately measure the real rate of inflation in a particular emerging market or in the emerging markets in which the Fund invests or in the United States. These securities may lose value in the event that the actual rate of inflation is different than the rate of the inflation index. In addition, changes in foreign exchange rates may negate the impact of any adjustments to interest rates payable on the securities for non-U.S. dollar denominated inflation-linked securities.

Investment Company Risk. Shareholders bear both their proportionate share of the Fund's expenses and similar expenses of another investment company in which the Fund may invest.

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.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund's performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Non-Diversified Fund Risk. Since the Fund is non-diversified, it may invest a greater percentage of its assets in a particular issuer or group of issuers than a diversified fund would. This increased investment in fewer issuers may result in the Fund's shares being more sensitive to economics results of those issuing the securities.

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.

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. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 189% of the average value of its portfolio.

What are the Fund’s main investment strategies?

The Fund invests primarily in debt investments that it believes have the potential to provide total return from countries whose economies or bond markets are less developed (emerging markets). The Fund's adviser, J.P. Morgan Investment Management Inc. (JPMIM or the adviser) uses a flexible asset allocation approach to invest the Fund opportunistically among different emerging market sectors and instruments. Under normal circumstances, the Fund invests at least 80% of its Assets in emerging market debt investments. "Emerging market debt investments" are securities and instruments of issuers located in or tied economically to emerging markets. "Assets" means net assets, plus the amount of borrowings for investment purposes. Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. Emerging markets currently include most countries in the world except Australia, Canada, Japan, New Zealand, the U.S., the United Kingdom, and most of the countries of western Europe and Hong Kong. A security will be deemed to be tied economically to emerging markets if: (1) the issuer is organized under the laws of, or has a principal place of business in an emerging market; or (2) the principal listing of the issuer's securities is in a market that is in an emerging market; or (3) the issuer derives at least 50% of its total revenues or profits from goods that are produced or sold, investments made, or services performed in an emerging market; or (4) the issuer has at least 50% of its assets located in an emerging market.

The Fund is unconstrained and may invest in a broad array of emerging market debt securities and sectors including corporate debt and sovereign debt. These securities may be denominated in U.S. and other developed market currencies as well as emerging markets currencies (local currencies). Sovereign debt securities are securities that are issued or guaranteed by foreign sovereign governments or their agencies, authorities or political subdivisions or instrumentalities, and supranational agencies. The Fund may invest in debt securities issued or guaranteed by foreign corporations and foreign financial institutions.

The Fund's securities may be of any maturity, duration or quality. The Fund does not have any minimum quality rating requirement and may invest without limit in securities that are rated below investment grade (commonly known as junk bonds) or the unrated equivalent. As part of its principal investment strategies, the Fund may invest in foreign municipal securities, including foreign provincial securities, fixed and floating or variable rate instruments, inflation-linked securities, corporate debt securities, private placements, zero-coupon securities and loan participation notes. The Fund may also invest in structured investments such as credit linked notes (CLNs) involving U.S. or non-U.S. counterparties for which the reference instrument is an emerging markets debt instrument denominated in an emerging markets currency. CLNs are typically structured as a limited purpose trust or other vehicle that, in turn, invests in a derivative or basket of derivative instruments, such as credit default swaps, interest rate swaps and/or other securities, in order to provide exposure to emerging markets.

Derivatives are instruments that have a value based on another instrument, exchange rate or index. In addition to direct investments in securities, the Fund will use derivatives as a substitute for securities in which the Fund can invest. The Fund may use derivatives including foreign currency transactions such as currency forwards including non-deliverable forwards, futures contracts, options, swaps such as interest rate swaps and credit default swaps, and securities with embedded derivatives such as CLNs. The Fund may use swaps structured as credit default swaps related to individual securities or indexes of securities to gain or to limit exposure to securities, to mitigate risk exposure and to manage cash flow needs. The Fund may also use foreign currency transactions, futures contracts, options, credit default swaps and currency options to help manage duration, sector and yield curve exposure and credit and spread volatility and to establish or adjust exposure to particular foreign securities, markets or currencies. The Fund also may use derivatives to hedge an investment in one currency back to another currency, to increase income and gain to the Fund, and/or as part of its risk management process by establishing or adjusting exposure to particular foreign securities, markets or currencies.

The Fund may invest in registered investment companies including J.P. Morgan money market funds, securities issued by the U.S. government and its agencies, or other investments to maintain asset coverage for the Fund's derivative positions and for cash management purposes.

The adviser buys and sells securities and investments for the Fund based on its view of individual securities and market sectors, combining macro-economic research with bottom up fundamental country and credit analysis. The adviser analyzes rates and foreign exchanges separately using a quantitative assessment with a qualitative overlay. Taking a long-term approach, the adviser looks for individual fixed income investments that it believes will perform well over market cycles. The adviser is value oriented and makes decisions to purchase and sell individual securities and instruments after performing a risk/reward analysis that includes an evaluation of interest rate risk, currency risk, credit risk, duration, liquidity and the complex legal and technical structure of the transaction.

The Fund is non-diversified.

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 instruments 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund's performance and ability to meet its investment objective.

Foreign Securities and Emerging Markets Risk. Investments in foreign issuers and foreign securities are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, sanctions or other measures by the United States or other governments, 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 or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. 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. These risks are magnified in countries in "emerging markets." Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

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. Securities in the Fund's portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

European Market Risk. The Fund's performance will be affected by political, social and economic conditions in Europe, such as growth of the economic output (the gross national product), the rate of inflation, the rate at which capital is reinvested into European economies, the success of governmental actions to reduce budget deficits, the resource self-sufficiency of European countries and interest and monetary exchange rates between European countries. European financial markets may experience volatility due to concerns about high government debt levels, credit rating downgrades, rising unemployment, the future of the euro as a common currency, possible restructuring of government debt and other government measures responding to those concerns, and fiscal and monetary controls imposed on member countries of the European Union. The risk of investing in Europe may be heightened due to the referendum in which the United Kingdom voted to exit the European Union. In addition, if one or more countries were to exit the European Union or abandon the use of the euro as a currency, the value of investments tied to those countries or the euro could decline significantly and unpredictably.

Sovereign Debt Risk. Sovereign debt investments are subject to the risk of payment delays or defaults, due, for example, to cash flow problems, insufficient foreign currency reserves, political considerations, large debt positions relative to the country's economy or failure to implement economic reforms. There is no legal or bankruptcy process for collecting sovereign debt.

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 impacted by that currency loses value because that currency is worth less in U.S. dollars. Currency exchange rates may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates. 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. Although the Fund may attempt to hedge its currency exposure into the U.S. dollar, it may not be successful in reducing 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.

Interest Rate Risk. The Fund's investments in bonds and other debt securities will change in value based on changes in interest rates. If rates rise, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given the historically low interest rate environment, risks associated with rising rates are heightened.

Credit Risk. The Fund's investments are subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund's investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund's securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer's securities.

Derivatives Risk. Derivatives, including currency forwards, interest rate swaps and currency options, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be particularly 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 expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). 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. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the currency, security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation. Certain of the Fund's transactions in foreign currency derivatives and other derivatives could also affect the amount, timing and character of distributions to shareholders which may result in the Fund realizing more short-term capital gain and ordinary income subject to tax at ordinary income tax rates than it would if it did not engage in such transactions, which may adversely impact the Fund's after-tax returns.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares' values may fluctuate in response to events affecting that industry or sector.

High Yield Securities Risk. The Fund may invest in securities that are obligations of companies that are highly leveraged, less creditworthy or financially distressed. These investments (known as junk bonds) are considered to be speculative and are subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties and potential illiquidity.

Foreign Municipal Securities Risk. The risk of a foreign municipal security generally depends on the financial and credit status of the issuer, which in turn will depend on the local economic, regulatory, political and other factors and conditions. Changes in a municipality's financial health may make it difficult for the municipality to make interest and principal payments when due. This could decrease the Fund's income or hurt the ability to preserve capital and liquidity. Under some circumstances, municipal securities might not pay interest unless the applicable legislature or municipality authorizes money for that purpose. In addition, the issuer of the obligations may be unable or unwilling to make interest and principal payments when due. These securities are also subject to foreign and emerging markets risks based on the location of the issuer.

Privately Placed Securities Risk. Privately placed securities generally are less liquid than publicly traded securities and the Fund may not always be able to sell such securities without experiencing delays in finding buyers or reducing the sale price for such securities. The disposition of some of the securities held by the Fund may be restricted under federal securities laws. As a result, the Fund may not be able to dispose of such investments at a time when, or at a price at which, it desires to do so and may have to bear expenses of registering these securities, if necessary. These securities may also be difficult to value.

CLN Risk. CLNs are synthetic instruments that are subject to the counterparty risk described above under "Credit Risk." In the event of a default, the Fund does not have a right in the underlying reference debt obligation. Generally, payments under the CLN are conditioned on the CLN's receipt of payments from, and the CLN's potential obligations, to the counterparties to the derivative instruments and other securities in which the CLN invests. If a default were to occur, the stream of payments may stop and the CLN would be obligated to pay the counterparty the par value (or other agreed upon value) of the referenced debt obligation. This, in turn, would reduce the amount of income and principal that the Fund would receive as an investor in the CLN.

Zero-Coupon, Pay-In-Kind and Deferred Payment Securities Risk. The market value of a zero-coupon, pay-in-kind or deferred payment security is generally more volatile than the market value of, and is more likely to respond to a greater degree to changes in interest rates than, other fixed income securities with similar maturities and credit quality that pay interest periodically. In addition, federal income tax law requires that the holder of a zero-coupon security accrue a portion of the discount at which the security was purchased as taxable income each year. The Fund may consequently have to dispose of portfolio securities under disadvantageous circumstances to generate cash to satisfy its requirement as a regulated investment company to distribute all of its net income.

Inflation-Linked Security Risk. Inflation-linked emerging markets debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of an inflation-linked security tends to decline when real interest rates increase. Unlike conventional bonds, the principal and interest payments of inflation-linked securities may be adjusted periodically to a specified rate of inflation. There can be no assurance that the inflation index used will accurately measure the real rate of inflation in a particular emerging market or in the emerging markets in which the Fund invests or in the United States. These securities may lose value in the event that the actual rate of inflation is different than the rate of the inflation index. In addition, changes in foreign exchange rates may negate the impact of any adjustments to interest rates payable on the securities for non-U.S. dollar denominated inflation-linked securities.

Investment Company Risk. Shareholders bear both their proportionate share of the Fund's expenses and similar expenses of another investment company in which the Fund may invest.

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.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund's performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Non-Diversified Fund Risk. Since the Fund is non-diversified, it may invest a greater percentage of its assets in a particular issuer or group of issuers than a diversified fund would. This increased investment in fewer issuers may result in the Fund's shares being more sensitive to economics results of those issuing the securities.

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.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how performance of the Fund’s Class R6 Shares has varied from year to year over the past four calendar years. The table shows the average annual total returns over the past one year and life of the Fund. The table compares that performance to the J.P. Morgan Emerging Markets Bond Index (EMBI) Global Diversified, the J.P. Morgan Government Bond Index-Emerging Markets (GBI-EM) Global Diversified, the Emerging Markets Strategic Debt Composite Benchmark (a composite benchmark of the equally weighted average of J.P. Morgan EMBI Global Diversified, J.P. Morgan GBI-EM Global Diversified and J.P. Morgan Corporate Emerging Markets Bond Index (CEMBI) Broad Diversified) and the Lipper Emerging Markets Local Currency Debt Funds Index. The Lipper index is based on the total return of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other indexes, the Lipper index includes the fees and expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

Effective September 30, 2016 (the “Effective Date”), some of the Fund’s investment strategies changed. The Fund’s past performance would have been different if the Fund were managed using the current strategies. On the Effective Date, the Fund’s broad based securities market index changed from the J.P. Morgan GBI-EM Global Diversified to the J.P. Morgan Emerging Markets Bond Index (EMBI) Global Diversified to reflect the change in the Fund’s investment strategies.

Emerging markets currently include most countries in the world except Australia, Canada, Japan, New Zealand, the U.S., the United Kingdom, and most of the countries of western Europe and Hong Kong. A security will be deemed to be tied economically to emerging markets if: (1) the issuer is organized under the laws of, or has a principal place of business in an emerging market; or (2) the principal listing of the issuer's securities is in a market that is in an emerging market; or (3) the issuer derives at least 50% of its total revenues or profits from goods that are produced or sold, investments made, or services performed in an emerging market; or (4) the issuer has at least 50% of its assets located in an emerging market.

These securities may be denominated in U.S. and other developed market currencies as well as emerging markets currencies (local currencies). Sovereign debt securities are securities that are issued or guaranteed by foreign sovereign governments or their agencies, authorities or political subdivisions or instrumentalities, and supranational agencies. The Fund may invest in debt securities issued or guaranteed by foreign corporations and foreign financial institutions.

The Fund's securities may be of any maturity, duration or quality. The Fund does not have any minimum quality rating requirement and may invest without limit in securities that are rated below investment grade (commonly known as junk bonds) or the unrated equivalent. As part of its principal investment strategies, the Fund may invest in foreign municipal securities, including foreign provincial securities, fixed and floating or variable rate instruments, inflation-linked securities, corporate debt securities, private placements, zero-coupon securities and loan participation notes. The Fund may also invest in structured investments such as credit linked notes (CLNs) involving U.S. or non-U.S. counterparties for which the reference instrument is an emerging markets debt instrument denominated in an emerging markets currency. CLNs are typically structured as a limited purpose trust or other vehicle that, in turn, invests in a derivative or basket of derivative instruments, such as credit default swaps, interest rate swaps and/or other securities, in order to provide exposure to emerging markets.

Derivatives are instruments that have a value based on another instrument, exchange rate or index. In addition to direct investments in securities, the Fund will use derivatives as a substitute for securities in which the Fund can invest. The Fund may use derivatives including foreign currency transactions such as currency forwards including non-deliverable forwards, futures contracts, options, swaps such as interest rate swaps and credit default swaps, and securities with embedded derivatives such as CLNs. The Fund may use swaps structured as credit default swaps related to individual securities or indexes of securities to gain or to limit exposure to securities, to mitigate risk exposure and to manage cash flow needs. The Fund may also use foreign currency transactions, futures contracts, options, credit default swaps and currency options to help manage duration, sector and yield curve exposure and credit and spread volatility and to establish or adjust exposure to particular foreign securities, markets or currencies. The Fund also may use derivatives to hedge an investment in one currency back to another currency, to increase income and gain to the Fund, and/or as part of its risk management process by establishing or adjusting exposure to particular foreign securities, markets or currencies.

The Fund may invest in registered investment companies including J.P. Morgan money market funds, securities issued by the U.S. government and its agencies, or other investments to maintain asset coverage for the Fund's derivative positions and for cash management purposes.

The adviser buys and sells securities and investments for the Fund based on its view of individual securities and market sectors, combining macro-economic research with bottom up fundamental country and credit analysis. The adviser analyzes rates and foreign exchanges separately using a quantitative assessment with a qualitative overlay. Taking a long-term approach, the adviser looks for individual fixed income investments that it believes will perform well over market cycles. The adviser is value oriented and makes decisions to purchase and sell individual securities and instruments after performing a risk/reward analysis that includes an evaluation of interest rate risk, currency risk, credit risk, duration, liquidity and the complex legal and technical structure of the transaction.

The Fund is non-diversified.

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 instruments 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund's performance and ability to meet its investment objective.

Foreign Securities and Emerging Markets Risk. Investments in foreign issuers and foreign securities are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, sanctions or other measures by the United States or other governments, 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 or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. 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. These risks are magnified in countries in "emerging markets." Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

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. Securities in the Fund's portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

European Market Risk. The Fund's performance will be affected by political, social and economic conditions in Europe, such as growth of the economic output (the gross national product), the rate of inflation, the rate at which capital is reinvested into European economies, the success of governmental actions to reduce budget deficits, the resource self-sufficiency of European countries and interest and monetary exchange rates between European countries. European financial markets may experience volatility due to concerns about high government debt levels, credit rating downgrades, rising unemployment, the future of the euro as a common currency, possible restructuring of government debt and other government measures responding to those concerns, and fiscal and monetary controls imposed on member countries of the European Union. The risk of investing in Europe may be heightened due to the referendum in which the United Kingdom voted to exit the European Union. In addition, if one or more countries were to exit the European Union or abandon the use of the euro as a currency, the value of investments tied to those countries or the euro could decline significantly and unpredictably.

Sovereign Debt Risk. Sovereign debt investments are subject to the risk of payment delays or defaults, due, for example, to cash flow problems, insufficient foreign currency reserves, political considerations, large debt positions relative to the country's economy or failure to implement economic reforms. There is no legal or bankruptcy process for collecting sovereign debt.

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 impacted by that currency loses value because that currency is worth less in U.S. dollars. Currency exchange rates may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates. 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. Although the Fund may attempt to hedge its currency exposure into the U.S. dollar, it may not be successful in reducing 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.

Interest Rate Risk. The Fund's investments in bonds and other debt securities will change in value based on changes in interest rates. If rates rise, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Given the historically low interest rate environment, risks associated with rising rates are heightened.

Credit Risk. The Fund's investments are subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund's investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund's securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer's securities.

Derivatives Risk. Derivatives, including currency forwards, interest rate swaps and currency options, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be particularly 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 expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). 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. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the currency, security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation. Certain of the Fund's transactions in foreign currency derivatives and other derivatives could also affect the amount, timing and character of distributions to shareholders which may result in the Fund realizing more short-term capital gain and ordinary income subject to tax at ordinary income tax rates than it would if it did not engage in such transactions, which may adversely impact the Fund's after-tax returns.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares' values may fluctuate in response to events affecting that industry or sector.

High Yield Securities Risk. The Fund may invest in securities that are obligations of companies that are highly leveraged, less creditworthy or financially distressed. These investments (known as junk bonds) are considered to be speculative and are subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties and potential illiquidity.

Foreign Municipal Securities Risk. The risk of a foreign municipal security generally depends on the financial and credit status of the issuer, which in turn will depend on the local economic, regulatory, political and other factors and conditions. Changes in a municipality's financial health may make it difficult for the municipality to make interest and principal payments when due. This could decrease the Fund's income or hurt the ability to preserve capital and liquidity. Under some circumstances, municipal securities might not pay interest unless the applicable legislature or municipality authorizes money for that purpose. In addition, the issuer of the obligations may be unable or unwilling to make interest and principal payments when due. These securities are also subject to foreign and emerging markets risks based on the location of the issuer.

Privately Placed Securities Risk. Privately placed securities generally are less liquid than publicly traded securities and the Fund may not always be able to sell such securities without experiencing delays in finding buyers or reducing the sale price for such securities. The disposition of some of the securities held by the Fund may be restricted under federal securities laws. As a result, the Fund may not be able to dispose of such investments at a time when, or at a price at which, it desires to do so and may have to bear expenses of registering these securities, if necessary. These securities may also be difficult to value.

CLN Risk. CLNs are synthetic instruments that are subject to the counterparty risk described above under "Credit Risk." In the event of a default, the Fund does not have a right in the underlying reference debt obligation. Generally, payments under the CLN are conditioned on the CLN's receipt of payments from, and the CLN's potential obligations, to the counterparties to the derivative instruments and other securities in which the CLN invests. If a default were to occur, the stream of payments may stop and the CLN would be obligated to pay the counterparty the par value (or other agreed upon value) of the referenced debt obligation. This, in turn, would reduce the amount of income and principal that the Fund would receive as an investor in the CLN.

Zero-Coupon, Pay-In-Kind and Deferred Payment Securities Risk. The market value of a zero-coupon, pay-in-kind or deferred payment security is generally more volatile than the market value of, and is more likely to respond to a greater degree to changes in interest rates than, other fixed income securities with similar maturities and credit quality that pay interest periodically. In addition, federal income tax law requires that the holder of a zero-coupon security accrue a portion of the discount at which the security was purchased as taxable income each year. The Fund may consequently have to dispose of portfolio securities under disadvantageous circumstances to generate cash to satisfy its requirement as a regulated investment company to distribute all of its net income.

Inflation-Linked Security Risk. Inflation-linked emerging markets debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of an inflation-linked security tends to decline when real interest rates increase. Unlike conventional bonds, the principal and interest payments of inflation-linked securities may be adjusted periodically to a specified rate of inflation. There can be no assurance that the inflation index used will accurately measure the real rate of inflation in a particular emerging market or in the emerging markets in which the Fund invests or in the United States. These securities may lose value in the event that the actual rate of inflation is different than the rate of the inflation index. In addition, changes in foreign exchange rates may negate the impact of any adjustments to interest rates payable on the securities for non-U.S. dollar denominated inflation-linked securities.

Investment Company Risk. Shareholders bear both their proportionate share of the Fund's expenses and similar expenses of another investment company in which the Fund may invest.

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.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund's performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Non-Diversified Fund Risk. Since the Fund is non-diversified, it may invest a greater percentage of its assets in a particular issuer or group of issuers than a diversified fund would. This increased investment in fewer issuers may result in the Fund's shares being more sensitive to economics results of those issuing the securities.

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.

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. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 41% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal circumstances, the Fund invests at least 80% of its Assets in equity securities. “Assets” means net assets, plus the amount of borrowings for investment purposes. In implementing its main strategy, the Fund primarily invests in common stocks of large and medium capitalization U.S. companies, but it may also invest up to 20% of its Assets in common stocks of foreign companies, including depositary receipts. Large and medium capitalization companies are companies with market capitalizations equal to those within the universe of the S&P 500 Index at the time of purchase. As of December 31, 2016, the market capitalizations of the companies in the S&P 500 Index ranged from $2.3 billion to $617.6 billion.

Sector by sector, the Fund’s weightings are similar to those of the S&P 500 Index. Within each sector, the Fund focuses on those equity securities that it considers undervalued and seeks to outperform the S&P 500 through superior stock selection. By emphasizing undervalued securities, the Fund seeks to produce returns that exceed those of the S&P 500 Index. At the same time, by controlling the sector weightings of the Fund so that they can differ only moderately from the sector weightings of the S&P 500 Index, the Fund seeks to limits its volatility to that of the overall market, as represented by this index.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

The Fund seeks to minimize shareholders’ tax liability in connection with the Fund’s distribution of realized capital gain by minimizing the net gains available for distribution. As part of its tax aware strategy, the Fund typically sells securities when the anticipated performance benefit justifies the resulting gain. This strategy often includes minimizing the sale of securities with large unrealized gain, holding securities long enough to avoid short-term capital gains taxes, selling securities with a higher cost basis first and offsetting capital gains realized in one security by selling another security at a capital loss. In addition, the Fund seeks to minimize distributions that are taxed as ordinary income and not qualified dividend income.

Investment Process: In managing the Fund, the adviser employs a three-step process that combines research, valuation and stock selection. The adviser takes an in-depth look at company prospects over a period as long as five years, which is designed to provide insight into a company’s real growth potential. The research findings allow the adviser to rank the companies in each sector group according to what it believes to be their relative value.

On behalf of the Fund, the adviser then buys and sells equity securities, using the research and valuation rankings as a basis. In general, the adviser buys equity securities that are identified as undervalued and considers selling them when they appear overvalued. Along with attractive valuation, the adviser often considers a number of other criteria:

• catalysts that could trigger a rise in a stock’s price

• high perceived potential reward compared to perceived potential risk

• possible temporary mispricings caused by apparent market overreactions

The frequency with which the Fund buys and sells securities will vary from year to year, depending on market conditions and the implementation of the tax aware strategy.

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 instruments 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

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. When the value of the Fund’s securities does down, your investment in the Fund decreases in value.

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. Securities in the Fund’s portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Mid Cap Company Risk. The Fund may invest in large and mid capitalization companies, and the Fund’s risks increase as it invests more heavily in mid capitalization companies. Investments in mid cap companies may be riskier, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of mid-cap companies may trade less frequently and in smaller volumes than securities of larger 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.

Value Strategy Risk. An undervalued 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.

Tax Aware Investing Risk. The Fund’s tax aware strategies may reduce your taxable income, but will not eliminate it. These strategies may require trade-offs that reduce pretax income. Managing the Fund to maximize after-tax returns may also potentially have a negative effect on the Fund’s performance. Because tax consequences are considered in managing the Fund, the Fund’s pre-tax performance may be lower than that of a similar fund that is not tax-managed.

Smaller Company Risk. Investments in securities of smaller companies may be riskier, less liquid, more volatile and vulnerable to economic, market and industry changes than securities of larger more established companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Real Estate Securities Risk. The value of real estate securities in general, and REITs in particular, are subject to the same risks as direct investments in real estate and mortgages which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy and environmental factors. The underlying mortgage loans may be subject to the risks of default or of prepayments that occur earlier or later than expected, and such loans may also include so-called “sub-prime” mortgages.

Derivatives Risk. Derivatives, including futures, 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 expose the Fund to counterparty risk which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). 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.

Foreign Securities 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, sanctions or other measures by the United States or other governments, 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 or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. 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.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

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.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Institutional Class Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years and ten years. The table compares that performance to the S&P 500 Index and the Lipper Large-Cap Core Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the fees and expenses of the mutual funds included in the index. The performance of Class A and Class C Shares shown in the table is based on the performance of the Institutional Class Shares prior to the inception of the Class A and Class C Shares. The actual returns of Class A and Class C Shares would have been lower because each of these classes has higher expenses than Institutional Class Shares. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

The bar chart shows how the performance of the Fund’s Institutional Class Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years and ten years. The table compares that performance to the S&P 500 Index and the Lipper Large-Cap Core Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the fees and expenses of the mutual funds included in the index. The performance of Class A and Class C Shares shown in the table is based on the performance of the Institutional Class Shares prior to the inception of the Class A and Class C Shares. The actual returns of Class A and Class C Shares would have been lower because each of these classes has higher expenses than Institutional Class Shares. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

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. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/18 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

IF YOU SELL YOUR SHARES, YOUR COST WOULD BE:

Expense Example - A, C, Institutional Shares - JPMorgan Tax Aware Real Return Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	449	635	852	1,477
CLASS C SHARES	227	427	763	1,716
INSTITUTIONAL CLASS SHARES	51	170	306	702

IF YOU DO NOT SELL YOUR SHARES, YOUR COST
WOULD BE:

Expense Example, No Redemption - A, C, Institutional Shares - JPMorgan Tax Aware Real Return Fund - USD ($)	1 Year	3 Years	5 Years	10 Years

INSTITUTIONAL CLASS SHARES	51	170	306	702

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. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 7% of the average value of its portfolio.

What are the Fund’s main investment strategies?

The Fund is designed to protect after-tax return by, under normal circumstances, primarily investing in a portfolio of municipal obligations whose interest payments are excluded from federal income taxes. The Fund is also designed to maximize inflation-protected return, which means maximizing the “real return.” Real Return is the total return of a security less the actual rate of inflation. Because of the limited supply of inflation-protected municipal securities, the Fund seeks to synthetically create inflation protection by investing in a combination of conventional (i.e., non-inflation protected) municipal securities and inflation-linked derivatives such as Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U) swaps. The adviser may use other strategies to achieve the Fund’s objective including investments in other types of securities which provide after-tax return and direct investments in inflation-linked securities such as Treasury Inflation Protected Securities (TIPS) and municipal inflation-linked securities, if available.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may also be used as substitutes for securities in which the Fund may invest. As part of its principal investment strategy, the Fund will invest substantially in swaps in which the Fund receives inflation- linked payments that provide inflation protection.

The Fund also may invest in taxable debt securities, including but not limited to, asset-backed and mortgage-related securities, U.S. government and agency securities, domestic corporate bonds and money market instruments and repurchase agreements. The Fund may engage in short sales including short sales of forward commitments. The Fund may also invest in repurchase agreements.

The average weighted maturity of the Fund’s portfolio will be between three and ten years. Average weighted maturity is the average of all the current maturities (that is, the term of the securities) of the individual bonds in a Fund calculated so as to count most heavily those securities with the highest dollar value. Average weighted maturity is important to investors as an indication of a Fund’s sensitivity to changes in interest rates. Usually, the longer the average weighted maturity, the more fluctuation in share price you can expect.

The Fund will invest primarily in securities that, at the time of purchase, are rated as investment grade by Moody’s Investors Service Inc. (Moody’s), Standard & Poor’s Corporation (S&P), or Fitch Rating (Fitch), meaning that such securities will carry a minimum rating of Baa3, BBB–, or BBB–, respectively or the equivalent by another national rating organization, or are unrated but deemed by the adviser to be of comparable quality. No more than 10% of total assets may be invested in securities below investment grade (also known as junk bonds). A “junk bond” is a debt security that is rated below investment grade. Junk bonds also include unrated securities that the adviser believes to be of comparable quality to debt securities that are rated below investment grade. Junk bonds are also called “high yield bonds” and “non-investment grade bonds.” These securities generally are rated in the fifth or lower rating categories (for example, BB+ or lower by S&P and Ba1 or lower by Moody’s). These securities generally offer a higher yield than investment grade securities, but involve a high degree of risk. A security’s quality is determined at the time of purchase and securities that are rated investment grade or the unrated equivalent may be downgraded or decline in credit quality such that subsequently they would be deemed to be below investment grade. If the quality of an investment grade security is downgraded subsequent to purchase to below investment grade, the Fund may continue to hold the security.

The Fund seeks to minimize shareholders’ tax liability in connection with the Fund’s distribution of realized capital gain by minimizing the net gains available for distribution. As part of its tax aware strategy, the Fund typically sells securities when the anticipated performance benefit justifies the resulting gain. This strategy often includes minimizing the sale of securities with large unrealized gain, holding securities long enough to avoid short-term capital gains taxes, selling securities with a higher cost basis first and offsetting capital gains realized in one security by selling another security at a capital loss. In addition, the Fund seeks to minimize distributions that are taxed as ordinary income.

Investment Process: The adviser buys and sells securities and investments for the Fund based on its view of individual securities and sectors. Taking a long-term approach, the adviser looks for individual fixed income investments that it believes will perform well over market cycles. The adviser is value oriented and makes decisions to purchase and sell individual securities and instruments after performing a risk/reward analysis that includes an evaluation of interest rate risk, credit risk, duration, liquidity and the complex legal and technical structure of the transaction.

The frequency with which the Fund buys and sells securities will vary from year to year, depending on market conditions and the implementation of the tax aware strategy.

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 instruments 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Municipal Obligations Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Changes in a municipality’s financial health may make it difficult for the municipality to make interest and principal payments when due. This could decrease the Fund’s income or hurt its ability to preserve capital and liquidity. Under some circumstances, municipal obligations might not pay interest unless the state legislature or municipality authorizes money for that purpose.

Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. In addition, since some municipal obligations may be secured or guaranteed by banks and other institutions, the risk to the Fund could increase if the banking or financial sector suffers an economic downturn and/or if the credit ratings of the institutions issuing the guarantee are downgraded or at risk of being downgraded by a national rating organization. Such a downward revision or risk of being downgraded may have an adverse effect on the market prices of the bonds and thus the value of the Fund’s investments.

In addition to being downgraded, an insolvent municipality may file for bankruptcy. The reorganization of a municipality’s debts may significantly affect the rights of creditors and the value of the securities issued by the municipality and the value of the Fund’s investments. Interest on municipal obligations, while generally exempt from federal income tax, may not be exempt from federal alternative minimum tax.

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. Securities in the Fund’s portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Derivatives Risk. Derivatives, including swaps, 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 expose the Fund to counterparty risk which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). 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.

In addition to risks associated with derivatives in general, the Fund will also be subject to risks related to swap agreements. 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.

Strategy Risk. The Fund’s investments may not work to achieve the Fund’s objective. There is no guarantee that the use of derivatives and debt securities will mimic a portfolio of inflation-protected municipal securities.

Inflation-Linked Securities Risk. Inflation-linked securities, including CPI-U swaps, are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of an inflation-linked security tends to decline when real interest rates increase. Unlike conventional bonds, the principal or interest of inflation-linked securities such as TIPS is adjusted periodically to a specified rate of inflation (e.g., CPI-U). There can be no assurance that the inflation index used will accurately measure the real rate of inflation. These securities may lose value in the event that the actual rate of inflation is different than the rate of the inflation index.

Debt Securities and Other Callable Securities Risk. As part of its investment strategy, the Fund invests in debt securities. The issuers of these securities and other callable securities may be able to repay principal in advance, especially when interest rates fall. Changes in prepayment rates can affect the return on investment and yield of these securities. When debt obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield. The Fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss.

Government Securities Risk. The Fund invests in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Securities issued or guaranteed by U.S. government-related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

Interest Rate Risk. The Fund’s investments in bonds and other debt securities will change in value based on changes in interest rates. If rates rise, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Given the historically low interest rate environment, risks associated with rising rates are heightened.

Credit Risk. The Fund’s investments are subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

High Yield Securities Risk. The Fund may invest in high yield, high risk securities (also known as junk bonds) which are considered to be speculative. These investments may be issued by companies which are highly leveraged, less creditworthy or financially distressed. Although these investments generally provide a higher yield than higher-rated debt securities, the high degree of risk involved in these investments can result in substantial or total losses. These securities are subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and a potential lack of a secondary or public market for securities. The market price of these securities can change suddenly and unexpectedly.

Tax Aware Investing Risk. The Fund’s tax aware strategies may reduce your taxable income, but will not eliminate it. These strategies may require trade-offs that reduce pretax income. Managing the Fund to maximize after-tax returns may also potentially have a negative effect on the Fund’s performance. Because tax consequences are considered in managing the Fund, the Fund’s pre-tax performance may be lower than that of a similar fund that is not tax-managed.

Mortgage-Related and Other Asset-Backed Securities Risk. Mortgage-related and asset-backed securities, including certain municipal housing authority obligations, are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the assets underlying such securities. As a result, during periods of declining asset values, difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to prepayment and call risk. In periods of declining interest rates, the Fund may be subject to contraction risk which is the risk that borrowers will increase the rate at which they prepay the maturity value of mortgages and other obligations. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividend and yield. In periods of rising interest rates, the Fund may be subject to extension risk which is the risk that the expected maturity of an obligation will lengthen in duration due to a decrease in prepayments. As a result, in certain interest rate environments, the Fund may exhibit additional volatility. Collateralized mortgage obligations (CMOs), interest-only (IOs) and principal-only (POs) stripped mortgage-backed securities are more volatile and may be subject to a higher risk of non-payment than other mortgage related securities.

Short Selling Risk. The Fund may enter into short sales of certain securities and must borrow the securities to make delivery to the buyer. The Fund may not always be able to borrow a security it wants to sell short. The Fund also may be unable to close out an established short position at an acceptable price, and it may have to sell long positions at disadvantageous times to cover its short positions. In addition, the Fund may enter into short sales of instruments such as mortgage TBAs which do not involve borrowing a security. Furthermore, taking short positions in securities results in a form of leverage. Leverage involves special risks described under “Derivatives Risk.” The Fund’s loss on a short sale is potentially unlimited because there is no upward limit on the price a borrowed security could attain.

Taxability Risk. The Fund’s investments in municipal securities rely on the opinion of the issuer’s bond counsel that the interest paid on those securities will not be subject to federal income tax. Tax opinions are generally provided at the time the municipal security is initially issued. However, after the Fund buys a security, the Internal Revenue Service may determine that a bond issued as tax-exempt should in fact be taxable and the Fund’s dividends with respect to that bond might be subject to federal income tax.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Repurchase Agreement Risk. Repurchase agreements involve some risk to the Fund that the counterparty does not meet its obligation under the agreement.

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.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how performance of the Fund’s Class A Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years, and ten years. The table compares that performance to the Bloomberg Barclays U.S. 1–15 Year Blend (1–17) Municipal Bond Index, the Tax Aware Real Return Composite Benchmark, a composite benchmark which is comprised of unmanaged indexes that correspond to the Fund’s objective of after-tax inflation protected return, and the Lipper Intermediate Municipal Debt Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other indexes, the Lipper index includes the fees and expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is designed to protect after-tax return by, under normal circumstances, primarily investing in a portfolio of municipal obligations whose interest payments are excluded from federal income taxes. The Fund is also designed to maximize inflation-protected return, which means maximizing the “real return.” Real Return is the total return of a security less the actual rate of inflation. Because of the limited supply of inflation-protected municipal securities, the Fund seeks to synthetically create inflation protection by investing in a combination of conventional (i.e., non-inflation protected) municipal securities and inflation-linked derivatives such as Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U) swaps. The adviser may use other strategies to achieve the Fund’s objective including investments in other types of securities which provide after-tax return and direct investments in inflation-linked securities such as Treasury Inflation Protected Securities (TIPS) and municipal inflation-linked securities, if available.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may also be used as substitutes for securities in which the Fund may invest. As part of its principal investment strategy, the Fund will invest substantially in swaps in which the Fund receives inflation- linked payments that provide inflation protection.

The Fund also may invest in taxable debt securities, including but not limited to, asset-backed and mortgage-related securities, U.S. government and agency securities, domestic corporate bonds and money market instruments and repurchase agreements. The Fund may engage in short sales including short sales of forward commitments. The Fund may also invest in repurchase agreements.

The average weighted maturity of the Fund’s portfolio will be between three and ten years. Average weighted maturity is the average of all the current maturities (that is, the term of the securities) of the individual bonds in a Fund calculated so as to count most heavily those securities with the highest dollar value. Average weighted maturity is important to investors as an indication of a Fund’s sensitivity to changes in interest rates. Usually, the longer the average weighted maturity, the more fluctuation in share price you can expect.

The Fund will invest primarily in securities that, at the time of purchase, are rated as investment grade by Moody’s Investors Service Inc. (Moody’s), Standard & Poor’s Corporation (S&P), or Fitch Rating (Fitch), meaning that such securities will carry a minimum rating of Baa3, BBB–, or BBB–, respectively or the equivalent by another national rating organization, or are unrated but deemed by the adviser to be of comparable quality. No more than 10% of total assets may be invested in securities below investment grade (also known as junk bonds). A “junk bond” is a debt security that is rated below investment grade. Junk bonds also include unrated securities that the adviser believes to be of comparable quality to debt securities that are rated below investment grade. Junk bonds are also called “high yield bonds” and “non-investment grade bonds.” These securities generally are rated in the fifth or lower rating categories (for example, BB+ or lower by S&P and Ba1 or lower by Moody’s). These securities generally offer a higher yield than investment grade securities, but involve a high degree of risk. A security’s quality is determined at the time of purchase and securities that are rated investment grade or the unrated equivalent may be downgraded or decline in credit quality such that subsequently they would be deemed to be below investment grade. If the quality of an investment grade security is downgraded subsequent to purchase to below investment grade, the Fund may continue to hold the security.

The Fund seeks to minimize shareholders’ tax liability in connection with the Fund’s distribution of realized capital gain by minimizing the net gains available for distribution. As part of its tax aware strategy, the Fund typically sells securities when the anticipated performance benefit justifies the resulting gain. This strategy often includes minimizing the sale of securities with large unrealized gain, holding securities long enough to avoid short-term capital gains taxes, selling securities with a higher cost basis first and offsetting capital gains realized in one security by selling another security at a capital loss. In addition, the Fund seeks to minimize distributions that are taxed as ordinary income.

Investment Process: The adviser buys and sells securities and investments for the Fund based on its view of individual securities and sectors. Taking a long-term approach, the adviser looks for individual fixed income investments that it believes will perform well over market cycles. The adviser is value oriented and makes decisions to purchase and sell individual securities and instruments after performing a risk/reward analysis that includes an evaluation of interest rate risk, credit risk, duration, liquidity and the complex legal and technical structure of the transaction.

The frequency with which the Fund buys and sells securities will vary from year to year, depending on market conditions and the implementation of the tax aware strategy.

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 instruments 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Municipal Obligations Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Changes in a municipality’s financial health may make it difficult for the municipality to make interest and principal payments when due. This could decrease the Fund’s income or hurt its ability to preserve capital and liquidity. Under some circumstances, municipal obligations might not pay interest unless the state legislature or municipality authorizes money for that purpose.

Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. In addition, since some municipal obligations may be secured or guaranteed by banks and other institutions, the risk to the Fund could increase if the banking or financial sector suffers an economic downturn and/or if the credit ratings of the institutions issuing the guarantee are downgraded or at risk of being downgraded by a national rating organization. Such a downward revision or risk of being downgraded may have an adverse effect on the market prices of the bonds and thus the value of the Fund’s investments.

In addition to being downgraded, an insolvent municipality may file for bankruptcy. The reorganization of a municipality’s debts may significantly affect the rights of creditors and the value of the securities issued by the municipality and the value of the Fund’s investments. Interest on municipal obligations, while generally exempt from federal income tax, may not be exempt from federal alternative minimum tax.

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. Securities in the Fund’s portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Derivatives Risk. Derivatives, including swaps, 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 expose the Fund to counterparty risk which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). 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.

In addition to risks associated with derivatives in general, the Fund will also be subject to risks related to swap agreements. 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.

Strategy Risk. The Fund’s investments may not work to achieve the Fund’s objective. There is no guarantee that the use of derivatives and debt securities will mimic a portfolio of inflation-protected municipal securities.

Inflation-Linked Securities Risk. Inflation-linked securities, including CPI-U swaps, are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of an inflation-linked security tends to decline when real interest rates increase. Unlike conventional bonds, the principal or interest of inflation-linked securities such as TIPS is adjusted periodically to a specified rate of inflation (e.g., CPI-U). There can be no assurance that the inflation index used will accurately measure the real rate of inflation. These securities may lose value in the event that the actual rate of inflation is different than the rate of the inflation index.

Debt Securities and Other Callable Securities Risk. As part of its investment strategy, the Fund invests in debt securities. The issuers of these securities and other callable securities may be able to repay principal in advance, especially when interest rates fall. Changes in prepayment rates can affect the return on investment and yield of these securities. When debt obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield. The Fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss.

Government Securities Risk. The Fund invests in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Securities issued or guaranteed by U.S. government-related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

Interest Rate Risk. The Fund’s investments in bonds and other debt securities will change in value based on changes in interest rates. If rates rise, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Given the historically low interest rate environment, risks associated with rising rates are heightened.

Credit Risk. The Fund’s investments are subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

High Yield Securities Risk. The Fund may invest in high yield, high risk securities (also known as junk bonds) which are considered to be speculative. These investments may be issued by companies which are highly leveraged, less creditworthy or financially distressed. Although these investments generally provide a higher yield than higher-rated debt securities, the high degree of risk involved in these investments can result in substantial or total losses. These securities are subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and a potential lack of a secondary or public market for securities. The market price of these securities can change suddenly and unexpectedly.

Tax Aware Investing Risk. The Fund’s tax aware strategies may reduce your taxable income, but will not eliminate it. These strategies may require trade-offs that reduce pretax income. Managing the Fund to maximize after-tax returns may also potentially have a negative effect on the Fund’s performance. Because tax consequences are considered in managing the Fund, the Fund’s pre-tax performance may be lower than that of a similar fund that is not tax-managed.

Mortgage-Related and Other Asset-Backed Securities Risk. Mortgage-related and asset-backed securities, including certain municipal housing authority obligations, are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the assets underlying such securities. As a result, during periods of declining asset values, difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to prepayment and call risk. In periods of declining interest rates, the Fund may be subject to contraction risk which is the risk that borrowers will increase the rate at which they prepay the maturity value of mortgages and other obligations. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividend and yield. In periods of rising interest rates, the Fund may be subject to extension risk which is the risk that the expected maturity of an obligation will lengthen in duration due to a decrease in prepayments. As a result, in certain interest rate environments, the Fund may exhibit additional volatility. Collateralized mortgage obligations (CMOs), interest-only (IOs) and principal-only (POs) stripped mortgage-backed securities are more volatile and may be subject to a higher risk of non-payment than other mortgage related securities.

Short Selling Risk. The Fund may enter into short sales of certain securities and must borrow the securities to make delivery to the buyer. The Fund may not always be able to borrow a security it wants to sell short. The Fund also may be unable to close out an established short position at an acceptable price, and it may have to sell long positions at disadvantageous times to cover its short positions. In addition, the Fund may enter into short sales of instruments such as mortgage TBAs which do not involve borrowing a security. Furthermore, taking short positions in securities results in a form of leverage. Leverage involves special risks described under “Derivatives Risk.” The Fund’s loss on a short sale is potentially unlimited because there is no upward limit on the price a borrowed security could attain.

Taxability Risk. The Fund’s investments in municipal securities rely on the opinion of the issuer’s bond counsel that the interest paid on those securities will not be subject to federal income tax. Tax opinions are generally provided at the time the municipal security is initially issued. However, after the Fund buys a security, the Internal Revenue Service may determine that a bond issued as tax-exempt should in fact be taxable and the Fund’s dividends with respect to that bond might be subject to federal income tax.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Repurchase Agreement Risk. Repurchase agreements involve some risk to the Fund that the counterparty does not meet its obligation under the agreement.

JPMorgan Tax Aware Equity Fund

Class/Ticker: Select/JPESX

What is the goal of the Fund?

The Fund’s goal is to provide high after-tax total return from a portfolio of selected equity securities.

Fees and Expenses of the Fund

The following 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	Select Shares JPMorgan Tax Aware Equity Fund Select Class
Management Fees	0.35%
Distribution (Rule 12b-1) Fees	none
Other Expenses	0.36%
Shareholder Service Fees	0.25%
Remainder of Other Expenses	0.11%	[1]
Total Annual Fund Operating Expenses	0.71%
Fee Waivers and Expense Reimbursements	(0.16%)	[2]
Total Annual Fund Operating Expenses After Fee Waivers and Expense Reimbursements	0.55%	[2]

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. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/18 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

WHETHER OR NOT YOU SELL YOUR SHARES, YOUR
COST WOULD BE:

Expense Example	1 Year	3 Years	5 Years	10 Years
Select Shares | JPMorgan Tax Aware Equity Fund | SELECT CLASS SHARES | USD ($)	56	199	368	857

WHETHER OR NOT YOU SELL YOUR SHARES, YOUR
COST WOULD BE:

Expense Example, No Redemption	1 Year	3 Years	5 Years	10 Years
Select Shares | JPMorgan Tax Aware Equity Fund | SELECT CLASS SHARES | USD ($)	56	199	368	857

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. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 41% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal circumstances, the Fund invests at least 80% of its Assets in equity securities. “Assets” means net assets, plus the amount of borrowings for investment purposes. In implementing its main strategy, the Fund primarily invests in common stocks of large and medium capitalization U.S. companies, but it may also invest up to 20% of its Assets in common stocks of foreign companies, including depositary receipts. Large and medium capitalization companies are companies with market capitalizations equal to those within the universe of the S&P 500 Index at the time of purchase. As of December 31, 2016, the market capitalizations of the companies in the S&P 500 Index ranged from $2.3 billion to $617.6 billion.

Sector by sector, the Fund’s weightings are similar to those of the S&P 500 Index. Within each sector, the Fund focuses on those equity securities that it considers undervalued and seeks to outperform the S&P 500 through superior stock selection. By emphasizing undervalued securities, the Fund seeks to produce returns that exceed those of the S&P 500 Index. At the same time, by controlling the sector weightings of the Fund so that they can differ only moderately from the sector weightings of the S&P 500 Index, the Fund seeks to limits its volatility to that of the overall market, as represented by this index.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

The Fund seeks to minimize shareholders’ tax liability in connection with the Fund’s distribution of realized capital gain by minimizing the net gains available for distribution. As part of its tax aware strategy, the Fund typically sells securities when the anticipated performance benefit justifies the resulting gain. This strategy often includes minimizing the sale of securities with large unrealized gain, holding securities long enough to avoid short-term capital gains taxes, selling securities with a higher cost basis first and offsetting capital gains realized in one security by selling another security at a capital loss. In addition, the Fund seeks to minimize distributions that are taxed as ordinary income and not qualified dividend income.

Investment Process: In managing the Fund, the adviser employs a three-step process that combines research, valuation and stock selection. The adviser takes an in-depth look at company prospects over a period as long as five years, which is designed to provide insight into a company’s real growth potential. The research findings allow the adviser to rank the companies in each sector group according to what it believes to be their relative value.

On behalf of the Fund, the adviser then buys and sells equity securities, using the research and valuation rankings as a basis. In general, the adviser buys equity securities that are identified as undervalued and considers selling them when they appear overvalued. Along with attractive valuation, the adviser often considers a number of other criteria:

• catalysts that could trigger a rise in a stock’s price

• high perceived potential reward compared to perceived potential risk

• possible temporary mispricings caused by apparent market overreactions

The frequency with which the Fund buys and sells securities will vary from year to year, depending on market conditions and the implementation of the tax aware strategy.

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 instruments 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

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. When the value of the Fund’s securities does down, your investment in the Fund decreases in value.

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. Securities in the Fund’s portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Mid Cap Company Risk. The Fund may invest in large and mid capitalization companies, and the Fund’s risks increase as it invests more heavily in mid capitalization companies. Investments in mid cap companies may be riskier, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of mid-cap companies may trade less frequently and in smaller volumes than securities of larger 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.

Value Strategy Risk. An undervalued 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.

Tax Aware Investing Risk. The Fund’s tax aware strategies may reduce your taxable income, but will not eliminate it. These strategies may require trade-offs that reduce pretax income. Managing the Fund to maximize after-tax returns may also potentially have a negative effect on the Fund’s performance. Because tax consequences are considered in managing the Fund, the Fund’s pre-tax performance may be lower than that of a similar fund that is not tax-managed.

Smaller Company Risk. Investments in securities of smaller companies may be riskier, less liquid, more volatile and vulnerable to economic, market and industry changes than securities of larger more established companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Real Estate Securities Risk. The value of real estate securities in general, and REITs in particular, are subject to the same risks as direct investments in real estate and mortgages which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy and environmental factors. The underlying mortgage loans may be subject to the risks of default or of prepayments that occur earlier or later than expected, and such loans may also include so-called “sub-prime” mortgages.

Derivatives Risk. Derivatives, including futures, 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 expose the Fund to counterparty risk which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). 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.

Foreign Securities 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, sanctions or other measures by the United States or other governments, 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 or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. 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.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

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.

Along with attractive valuation, the adviser often considers a number of other criteria:

• catalysts that could trigger a rise in a stock’s price

• high perceived potential reward compared to perceived potential risk

• possible temporary mispricings caused by apparent market overreactions

The frequency with which the Fund buys and sells securities will vary from year to year, depending on market conditions and the implementation of the tax aware strategy.

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 instruments 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

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. When the value of the Fund’s securities does down, your investment in the Fund decreases in value.

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. Securities in the Fund’s portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Mid Cap Company Risk. The Fund may invest in large and mid capitalization companies, and the Fund’s risks increase as it invests more heavily in mid capitalization companies. Investments in mid cap companies may be riskier, more volatile and more vulnerable to economic, market and industry changes than investment in larger, more established companies. The securities of mid-cap companies may trade less frequently and in smaller volumes than securities of larger 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.

Value Strategy Risk. An undervalued 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.

Tax Aware Investing Risk. The Fund’s tax aware strategies may reduce your taxable income, but will not eliminate it. These strategies may require trade-offs that reduce pretax income. Managing the Fund to maximize after-tax returns may also potentially have a negative effect on the Fund’s performance. Because tax consequences are considered in managing the Fund, the Fund’s pre-tax performance may be lower than that of a similar fund that is not tax-managed.

Smaller Company Risk. Investments in securities of smaller companies may be riskier, less liquid, more volatile and vulnerable to economic, market and industry changes than securities of larger more established companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Real Estate Securities Risk. The value of real estate securities in general, and REITs in particular, are subject to the same risks as direct investments in real estate and mortgages which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy and environmental factors. The underlying mortgage loans may be subject to the risks of default or of prepayments that occur earlier or later than expected, and such loans may also include so-called “sub-prime” mortgages.

Derivatives Risk. Derivatives, including futures, 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 expose the Fund to counterparty risk which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). 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.

Foreign Securities 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, sanctions or other measures by the United States or other governments, 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 or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. 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.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

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.

COST WOULD BE:

Expense Example, No Redemption	1 Year	3 Years	5 Years	10 Years
Select Shares | JPMorgan Tax Aware Real Return Fund | SELECT CLASS SHARES | USD ($)	51	191	360	849

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. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 7% of the average value of its portfolio.

What are the Fund’s main investment strategies?

The Fund is designed to protect after-tax return by, under normal circumstances, primarily investing in a portfolio of municipal obligations whose interest payments are excluded from federal income taxes. The Fund is also designed to maximize inflation-protected return, which means maximizing the “real return.” Real Return is the total return of a security less the actual rate of inflation. Because of the limited supply of inflation-protected municipal securities, the Fund seeks to synthetically create inflation protection by investing in a combination of conventional (i.e., non-inflation protected) municipal securities and inflation-linked derivatives such as Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U) swaps. The adviser may use other strategies to achieve the Fund’s objective including investments in other types of securities which provide after-tax return and direct investments in inflation-linked securities such as Treasury Inflation Protected Securities (TIPS) and municipal inflation-linked securities, if available.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may also be used as substitutes for securities in which the Fund may invest. As part of its principal investment strategy, the Fund will invest substantially in swaps in which the Fund receives inflation- linked payments that provide inflation protection.

The Fund also may invest in taxable debt securities, including but not limited to, asset-backed and mortgage-related securities, U.S. government and agency securities, domestic corporate bonds and money market instruments and repurchase agreements. The Fund may engage in short sales including short sales of forward commitments. The Fund may also invest in repurchase agreements.

The average weighted maturity of the Fund’s portfolio will be between three and ten years. Average weighted maturity is the average of all the current maturities (that is, the term of the securities) of the individual bonds in a Fund calculated so as to count most heavily those securities with the highest dollar value. Average weighted maturity is important to investors as an indication of a Fund’s sensitivity to changes in interest rates. Usually, the longer the average weighted maturity, the more fluctuation in share price you can expect.

The Fund will invest primarily in securities that, at the time of purchase, are rated as investment grade by Moody’s Investors Service Inc. (Moody’s), Standard & Poor’s Corporation (S&P), or Fitch Rating (Fitch), meaning that such securities will carry a minimum rating of Baa3, BBB–, or BBB–, respectively or the equivalent by another national rating organization, or are unrated but deemed by the adviser to be of comparable quality. No more than 10% of total assets may be invested in securities below investment grade (also known as junk bonds). A “junk bond” is a debt security that is rated below investment grade. Junk bonds also include unrated securities that the adviser believes to be of comparable quality to debt securities that are rated below investment grade. Junk bonds are also called “high yield bonds” and “non-investment grade bonds.” These securities generally are rated in the fifth or lower rating categories (for example, BB+ or lower by S&P and Ba1 or lower by Moody’s). These securities generally offer a higher yield than investment grade securities, but involve a high degree of risk. A security’s quality is determined at the time of purchase and securities that are rated investment grade or the unrated equivalent may be downgraded or decline in credit quality such that subsequently they would be deemed to be below investment grade. If the quality of an investment grade security is downgraded subsequent to purchase to below investment grade, the Fund may continue to hold the security.

The Fund seeks to minimize shareholders’ tax liability in connection with the Fund’s distribution of realized capital gain by minimizing the net gains available for distribution. As part of its tax aware strategy, the Fund typically sells securities when the anticipated performance benefit justifies the resulting gain. This strategy often includes minimizing the sale of securities with large unrealized gain, holding securities long enough to avoid short-term capital gains taxes, selling securities with a higher cost basis first and offsetting capital gains realized in one security by selling another security at a capital loss. In addition, the Fund seeks to minimize distributions that are taxed as ordinary income.

Investment Process: The adviser buys and sells securities and investments for the Fund based on its view of individual securities and sectors. Taking a long-term approach, the adviser looks for individual fixed income investments that it believes will perform well over market cycles. The adviser is value oriented and makes decisions to purchase and sell individual securities and instruments after performing a risk/reward analysis that includes an evaluation of interest rate risk, credit risk, duration, liquidity and the complex legal and technical structure of the transaction.

The frequency with which the Fund buys and sells securities will vary from year to year, depending on market conditions and the implementation of the tax aware strategy.

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 instruments 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Municipal Obligations Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Changes in a municipality’s financial health may make it difficult for the municipality to make interest and principal payments when due. This could decrease the Fund’s income or hurt its ability to preserve capital and liquidity. Under some circumstances, municipal obligations might not pay interest unless the state legislature or municipality authorizes money for that purpose.

Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. In addition, since some municipal obligations may be secured or guaranteed by banks and other institutions, the risk to the Fund could increase if the banking or financial sector suffers an economic downturn and/or if the credit ratings of the institutions issuing the guarantee are downgraded or at risk of being downgraded by a national rating organization. Such a downward revision or risk of being downgraded may have an adverse effect on the market prices of the bonds and thus the value of the Fund’s investments.

In addition to being downgraded, an insolvent municipality may file for bankruptcy. The reorganization of a municipality’s debts may significantly affect the rights of creditors and the value of the securities issued by the municipality and the value of the Fund’s investments. Interest on municipal obligations, while generally exempt from federal income tax, may not be exempt from federal alternative minimum tax.

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. Securities in the Fund’s portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Derivatives Risk. Derivatives, including swaps, 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 expose the Fund to counterparty risk which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). 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.

In addition to risks associated with derivatives in general, the Fund will also be subject to risks related to swap agreements. 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.

Strategy Risk. The Fund’s investments may not work to achieve the Fund’s objective. There is no guarantee that the use of derivatives and debt securities will mimic a portfolio of inflation-protected municipal securities.

Inflation-Linked Securities Risk. Inflation-linked securities, including CPI-U swaps, are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of an inflation-linked security tends to decline when real interest rates increase. Unlike conventional bonds, the principal or interest of inflation-linked securities such as TIPS is adjusted periodically to a specified rate of inflation (e.g., CPI-U). There can be no assurance that the inflation index used will accurately measure the real rate of inflation. These securities may lose value in the event that the actual rate of inflation is different than the rate of the inflation index.

Debt Securities and Other Callable Securities Risk. As part of its investment strategy, the Fund invests in debt securities. The issuers of these securities and other callable securities may be able to repay principal in advance, especially when interest rates fall. Changes in prepayment rates can affect the return on investment and yield of these securities. When debt obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield. The Fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss.

Government Securities Risk. The Fund invests in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Securities issued or guaranteed by U.S. government-related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

Interest Rate Risk. The Fund’s investments in bonds and other debt securities will change in value based on changes in interest rates. If rates rise, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Given the historically low interest rate environment, risks associated with rising rates are heightened.

Credit Risk. The Fund’s investments are subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

High Yield Securities Risk. The Fund may invest in high yield, high risk securities (also known as junk bonds) which are considered to be speculative. These investments may be issued by companies which are highly leveraged, less creditworthy or financially distressed. Although these investments generally provide a higher yield than higher-rated debt securities, the high degree of risk involved in these investments can result in substantial or total losses. These securities are subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and a potential lack of a secondary or public market for securities. The market price of these securities can change suddenly and unexpectedly.

Tax Aware Investing Risk. The Fund’s tax aware strategies may reduce your taxable income, but will not eliminate it. These strategies may require trade-offs that reduce pretax income. Managing the Fund to maximize after-tax returns may also potentially have a negative effect on the Fund’s performance. Because tax consequences are considered in managing the Fund, the Fund’s pre-tax performance may be lower than that of a similar fund that is not tax-managed.

Mortgage-Related and Other Asset-Backed Securities Risk. Mortgage-related and asset-backed securities, including certain municipal housing authority obligations, are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the assets underlying such securities. As a result, during periods of declining asset values, difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to prepayment and call risk. In periods of declining interest rates, the Fund may be subject to contraction risk which is the risk that borrowers will increase the rate at which they prepay the maturity value of mortgages and other obligations. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividend and yield. In periods of rising interest rates, the Fund may be subject to extension risk which is the risk that the expected maturity of an obligation will lengthen in duration due to a decrease in prepayments. As a result, in certain interest rate environments, the Fund may exhibit additional volatility. Collateralized mortgage obligations (CMOs), interest-only (IOs) and principal-only (POs) stripped mortgage-backed securities are more volatile and may be subject to a higher risk of non-payment than other mortgage related securities.

Short Selling Risk. The Fund may enter into short sales of certain securities and must borrow the securities to make delivery to the buyer. The Fund may not always be able to borrow a security it wants to sell short. The Fund also may be unable to close out an established short position at an acceptable price, and it may have to sell long positions at disadvantageous times to cover its short positions. In addition, the Fund may enter into short sales of instruments such as mortgage TBAs which do not involve borrowing a security. Furthermore, taking short positions in securities results in a form of leverage. Leverage involves special risks described under “Derivatives Risk.” The Fund’s loss on a short sale is potentially unlimited because there is no upward limit on the price a borrowed security could attain.

Taxability Risk. The Fund’s investments in municipal securities rely on the opinion of the issuer’s bond counsel that the interest paid on those securities will not be subject to federal income tax. Tax opinions are generally provided at the time the municipal security is initially issued. However, after the Fund buys a security, the Internal Revenue Service may determine that a bond issued as tax-exempt should in fact be taxable and the Fund’s dividends with respect to that bond might be subject to federal income tax.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Repurchase Agreement Risk. Repurchase agreements involve some risk to the Fund that the counterparty does not meet its obligation under the agreement.

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.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how performance of the Fund’s Select Class Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years, and ten years. The table compares that performance to the Bloomberg Barclays U.S. 1–15 Year Blend (1–17) Municipal Bond Index, the Tax Aware Real Return Composite Benchmark, a composite benchmark which is comprised of unmanaged indexes that correspond to the Fund’s objective of after-tax inflation protected return, and the Lipper Intermediate Municipal Debt Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other indexes, the Lipper index includes the fees and expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is designed to protect after-tax return by, under normal circumstances, primarily investing in a portfolio of municipal obligations whose interest payments are excluded from federal income taxes. The Fund is also designed to maximize inflation-protected return, which means maximizing the “real return.” Real Return is the total return of a security less the actual rate of inflation. Because of the limited supply of inflation-protected municipal securities, the Fund seeks to synthetically create inflation protection by investing in a combination of conventional (i.e., non-inflation protected) municipal securities and inflation-linked derivatives such as Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U) swaps. The adviser may use other strategies to achieve the Fund’s objective including investments in other types of securities which provide after-tax return and direct investments in inflation-linked securities such as Treasury Inflation Protected Securities (TIPS) and municipal inflation-linked securities, if available.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may also be used as substitutes for securities in which the Fund may invest. As part of its principal investment strategy, the Fund will invest substantially in swaps in which the Fund receives inflation- linked payments that provide inflation protection.

The Fund also may invest in taxable debt securities, including but not limited to, asset-backed and mortgage-related securities, U.S. government and agency securities, domestic corporate bonds and money market instruments and repurchase agreements. The Fund may engage in short sales including short sales of forward commitments. The Fund may also invest in repurchase agreements.

The average weighted maturity of the Fund’s portfolio will be between three and ten years. Average weighted maturity is the average of all the current maturities (that is, the term of the securities) of the individual bonds in a Fund calculated so as to count most heavily those securities with the highest dollar value. Average weighted maturity is important to investors as an indication of a Fund’s sensitivity to changes in interest rates. Usually, the longer the average weighted maturity, the more fluctuation in share price you can expect.

The Fund will invest primarily in securities that, at the time of purchase, are rated as investment grade by Moody’s Investors Service Inc. (Moody’s), Standard & Poor’s Corporation (S&P), or Fitch Rating (Fitch), meaning that such securities will carry a minimum rating of Baa3, BBB–, or BBB–, respectively or the equivalent by another national rating organization, or are unrated but deemed by the adviser to be of comparable quality. No more than 10% of total assets may be invested in securities below investment grade (also known as junk bonds). A “junk bond” is a debt security that is rated below investment grade. Junk bonds also include unrated securities that the adviser believes to be of comparable quality to debt securities that are rated below investment grade. Junk bonds are also called “high yield bonds” and “non-investment grade bonds.” These securities generally are rated in the fifth or lower rating categories (for example, BB+ or lower by S&P and Ba1 or lower by Moody’s). These securities generally offer a higher yield than investment grade securities, but involve a high degree of risk. A security’s quality is determined at the time of purchase and securities that are rated investment grade or the unrated equivalent may be downgraded or decline in credit quality such that subsequently they would be deemed to be below investment grade. If the quality of an investment grade security is downgraded subsequent to purchase to below investment grade, the Fund may continue to hold the security.

The Fund seeks to minimize shareholders’ tax liability in connection with the Fund’s distribution of realized capital gain by minimizing the net gains available for distribution. As part of its tax aware strategy, the Fund typically sells securities when the anticipated performance benefit justifies the resulting gain. This strategy often includes minimizing the sale of securities with large unrealized gain, holding securities long enough to avoid short-term capital gains taxes, selling securities with a higher cost basis first and offsetting capital gains realized in one security by selling another security at a capital loss. In addition, the Fund seeks to minimize distributions that are taxed as ordinary income.

Investment Process: The adviser buys and sells securities and investments for the Fund based on its view of individual securities and sectors. Taking a long-term approach, the adviser looks for individual fixed income investments that it believes will perform well over market cycles. The adviser is value oriented and makes decisions to purchase and sell individual securities and instruments after performing a risk/reward analysis that includes an evaluation of interest rate risk, credit risk, duration, liquidity and the complex legal and technical structure of the transaction.

The frequency with which the Fund buys and sells securities will vary from year to year, depending on market conditions and the implementation of the tax aware strategy.

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 instruments 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Municipal Obligations Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Changes in a municipality’s financial health may make it difficult for the municipality to make interest and principal payments when due. This could decrease the Fund’s income or hurt its ability to preserve capital and liquidity. Under some circumstances, municipal obligations might not pay interest unless the state legislature or municipality authorizes money for that purpose.

Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. In addition, since some municipal obligations may be secured or guaranteed by banks and other institutions, the risk to the Fund could increase if the banking or financial sector suffers an economic downturn and/or if the credit ratings of the institutions issuing the guarantee are downgraded or at risk of being downgraded by a national rating organization. Such a downward revision or risk of being downgraded may have an adverse effect on the market prices of the bonds and thus the value of the Fund’s investments.

In addition to being downgraded, an insolvent municipality may file for bankruptcy. The reorganization of a municipality’s debts may significantly affect the rights of creditors and the value of the securities issued by the municipality and the value of the Fund’s investments. Interest on municipal obligations, while generally exempt from federal income tax, may not be exempt from federal alternative minimum tax.

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. Securities in the Fund’s portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Derivatives Risk. Derivatives, including swaps, 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 expose the Fund to counterparty risk which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). 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.

In addition to risks associated with derivatives in general, the Fund will also be subject to risks related to swap agreements. 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.

Strategy Risk. The Fund’s investments may not work to achieve the Fund’s objective. There is no guarantee that the use of derivatives and debt securities will mimic a portfolio of inflation-protected municipal securities.

Inflation-Linked Securities Risk. Inflation-linked securities, including CPI-U swaps, are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of an inflation-linked security tends to decline when real interest rates increase. Unlike conventional bonds, the principal or interest of inflation-linked securities such as TIPS is adjusted periodically to a specified rate of inflation (e.g., CPI-U). There can be no assurance that the inflation index used will accurately measure the real rate of inflation. These securities may lose value in the event that the actual rate of inflation is different than the rate of the inflation index.

Debt Securities and Other Callable Securities Risk. As part of its investment strategy, the Fund invests in debt securities. The issuers of these securities and other callable securities may be able to repay principal in advance, especially when interest rates fall. Changes in prepayment rates can affect the return on investment and yield of these securities. When debt obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield. The Fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss.

Government Securities Risk. The Fund invests in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. Securities issued or guaranteed by U.S. government-related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

Interest Rate Risk. The Fund’s investments in bonds and other debt securities will change in value based on changes in interest rates. If rates rise, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Given the historically low interest rate environment, risks associated with rising rates are heightened.

Credit Risk. The Fund’s investments are subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

High Yield Securities Risk. The Fund may invest in high yield, high risk securities (also known as junk bonds) which are considered to be speculative. These investments may be issued by companies which are highly leveraged, less creditworthy or financially distressed. Although these investments generally provide a higher yield than higher-rated debt securities, the high degree of risk involved in these investments can result in substantial or total losses. These securities are subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and a potential lack of a secondary or public market for securities. The market price of these securities can change suddenly and unexpectedly.

Tax Aware Investing Risk. The Fund’s tax aware strategies may reduce your taxable income, but will not eliminate it. These strategies may require trade-offs that reduce pretax income. Managing the Fund to maximize after-tax returns may also potentially have a negative effect on the Fund’s performance. Because tax consequences are considered in managing the Fund, the Fund’s pre-tax performance may be lower than that of a similar fund that is not tax-managed.

Mortgage-Related and Other Asset-Backed Securities Risk. Mortgage-related and asset-backed securities, including certain municipal housing authority obligations, are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the assets underlying such securities. As a result, during periods of declining asset values, difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to prepayment and call risk. In periods of declining interest rates, the Fund may be subject to contraction risk which is the risk that borrowers will increase the rate at which they prepay the maturity value of mortgages and other obligations. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividend and yield. In periods of rising interest rates, the Fund may be subject to extension risk which is the risk that the expected maturity of an obligation will lengthen in duration due to a decrease in prepayments. As a result, in certain interest rate environments, the Fund may exhibit additional volatility. Collateralized mortgage obligations (CMOs), interest-only (IOs) and principal-only (POs) stripped mortgage-backed securities are more volatile and may be subject to a higher risk of non-payment than other mortgage related securities.

Short Selling Risk. The Fund may enter into short sales of certain securities and must borrow the securities to make delivery to the buyer. The Fund may not always be able to borrow a security it wants to sell short. The Fund also may be unable to close out an established short position at an acceptable price, and it may have to sell long positions at disadvantageous times to cover its short positions. In addition, the Fund may enter into short sales of instruments such as mortgage TBAs which do not involve borrowing a security. Furthermore, taking short positions in securities results in a form of leverage. Leverage involves special risks described under “Derivatives Risk.” The Fund’s loss on a short sale is potentially unlimited because there is no upward limit on the price a borrowed security could attain.

Taxability Risk. The Fund’s investments in municipal securities rely on the opinion of the issuer’s bond counsel that the interest paid on those securities will not be subject to federal income tax. Tax opinions are generally provided at the time the municipal security is initially issued. However, after the Fund buys a security, the Internal Revenue Service may determine that a bond issued as tax-exempt should in fact be taxable and the Fund’s dividends with respect to that bond might be subject to federal income tax.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Repurchase Agreement Risk. Repurchase agreements involve some risk to the Fund that the counterparty does not meet its obligation under the agreement.

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. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 7% of the average value of its portfolio.

What are the Fund’s main investment strategies?

The Fund is designed to protect after-tax return by, under normal circumstances, primarily investing in a portfolio of municipal obligations whose interest payments are excluded from federal income taxes. The Fund is also designed to maximize inflation-protected return, which means maximizing the "real return." Real Return is the total return of a security less the actual rate of inflation. Because of the limited supply of inflation-protected municipal securities, the Fund seeks to synthetically create inflation protection by investing in a combination of conventional (i.e., non-inflation protected) municipal securities and inflation-linked derivatives such as Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U) swaps. The adviser may use other strategies to achieve the Fund's objective including investments in other types of securities which provide after-tax return and direct investments in inflation-linked securities such as Treasury Inflation Protected Securities (TIPS) and municipal inflation-linked securities, if available.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may also be used as substitutes for securities in which the Fund may invest. As part of its principal investment strategy, the Fund will invest substantially in swaps in which the Fund receives inflation-linked payments that provide inflation protection.

The Fund also may invest in taxable debt securities, including but not limited to, asset-backed and mortgage-related securities, U.S. government and agency securities, domestic corporate bonds and money market instruments and repurchase agreements. The Fund may engage in short sales including short sales of forward commitments. The Fund may also invest in repurchase agreements.

The average weighted maturity of the Fund's portfolio will be between three and ten years. Average weighted maturity is the average of all the current maturities (that is, the term of the securities) of the individual bonds in a Fund calculated so as to count most heavily those securities with the highest dollar value. Average weighted maturity is important to investors as an indication of a Fund's sensitivity to changes in interest rates. Usually, the longer the average weighted maturity, the more fluctuation in share price you can expect.

The Fund will invest primarily in securities that, at the time of purchase, are rated as investment grade by Moody's Investors Service Inc. (Moody's), Standard & Poor's Corporation (S&P), or Fitch Rating (Fitch), meaning that such securities will carry a minimum rating of Baa3, BBB–, or BBB–, respectively or the equivalent by another national rating organization, or are unrated but deemed by the adviser to be of comparable quality. No more than 10% of total assets may be invested in securities below investment grade (also known as junk bonds).

A "junk bond" is a debt security that is rated below investment grade. Junk bonds also include unrated securities that the adviser believes to be of comparable quality to debt securities that are rated below investment grade. Junk bonds are also called "high yield bonds" and "non-investment grade bonds." These securities generally are rated in the fifth or lower rating categories (for example, BB+ or lower by S&P and Ba1 or lower by Moody's). These securities generally offer a higher yield than investment grade securities, but involve a high degree of risk. A security's quality is determined at the time of purchase and securities that are rated investment grade or the unrated equivalent may be downgraded or decline in credit quality such that subsequently they would be deemed to be below investment grade. If the quality of an investment grade security is downgraded subsequent to purchase to below investment grade, the Fund may continue to hold the security.

The Fund seeks to minimize shareholders' tax liability in connection with the Fund's distribution of realized capital gain by minimizing the net gains available for distribution. As part of its tax aware strategy, the Fund typically sells securities when the anticipated performance benefit justifies the resulting gain. This strategy often includes minimizing the sale of securities with large unrealized gain, holding securities long enough to avoid short-term capital gains taxes, selling securities with a higher cost basis first and offsetting capital gains realized in one security by selling another security at a capital loss. In addition, the Fund seeks to minimize distributions that are taxed as ordinary income.

Investment Process: The adviser buys and sells securities and investments for the Fund based on its view of individual securities and sectors. Taking a long-term approach, the adviser looks for individual fixed income investments that it believes will perform well over market cycles. The adviser is value oriented and makes decisions to purchase and sell individual securities and instruments after performing a risk/reward analysis that includes an evaluation of interest rate risk, credit risk, duration, liquidity and the complex legal and technical structure of the transaction.

The frequency with which the Fund buys and sells securities will vary from year to year, depending on market conditions and the implementation of the tax aware strategy.

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 instruments 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund's performance and ability to meet its investment objective.

Municipal Obligations Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Changes in a municipality's financial health may make it difficult for the municipality to make interest and principal payments when due. This could decrease the Fund's income or hurt its ability to preserve capital and liquidity. Under some circumstances, municipal obligations might not pay interest unless the state legislature or municipality authorizes money for that purpose.

Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. In addition, since some municipal obligations may be secured or guaranteed by banks and other institutions, the risk to the Fund could increase if the banking or financial sector suffers an economic downturn and/or if the credit ratings of the institutions issuing the guarantee are downgraded or at risk of being downgraded by a national rating organization. Such a downward revision or risk of being downgraded may have an adverse effect on the market prices of the bonds and thus the value of the Fund's investments.

In addition to being downgraded, an insolvent municipality may file for bankruptcy. The reorganization of a municipality's debts may significantly affect the rights of creditors and the value of the securities issued by the municipality and the value of the Fund's investments. Interest on municipal obligations, while generally exempt from federal income tax, may not be exempt from federal alternative minimum tax.

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. Securities in the Fund's portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares' values may fluctuate in response to events affecting that industry or sector.

Derivatives Risk. Derivatives, including swaps, 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 expose the Fund to counterparty risk which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). 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.

In addition to risks associated with derivatives in general, the Fund will also be subject to risks related to swap agreements. 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.

Strategy Risk. The Fund's investments may not work to achieve the Fund's objective. There is no guarantee that the use of derivatives and debt securities will mimic a portfolio of inflation-protected municipal securities.

Inflation-Linked Securities Risk. Inflation-linked securities, including CPI-U swaps, are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general the price of an inflation-linked security tends to decline when real interest rates increase. Unlike conventional bonds, the principal or interest of inflation-linked securities such as TIPS is adjusted periodically to a specified rate of inflation (e.g., CPI-U). There can be no assurance that the inflation index used will accurately measure the real rate of inflation. These securities may lose value in the event that the actual rate of inflation is different than the rate of the inflation index.

Debt Securities and Other Callable Securities Risk. As part of its investment strategy, the Fund invests in debt securities. The issuers of these securities and other callable securities may be able to repay principal in advance, especially when interest rates fall. Changes in prepayment rates can affect the return on investment and yield of these securities. When debt obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield. The Fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss.

Government Securities Risk. The Fund invests in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. 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 will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

Interest Rate Risk. The Fund's investments in bonds and other debt securities will change in value based on changes in interest rates. If rates rise, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Given the historically low interest rate environment, risks associated with rising rates are heightened.

Credit Risk. The Fund's investments are subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund's investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund's securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer's securities.

High Yield Securities Risk. The Fund may invest in high yield, high risk securities (also known as junk bonds) which are considered to be speculative. These investments may be issued by companies which are highly leveraged, less creditworthy or financially distressed. Although these investments generally provide a higher yield than higher-rated debt securities, the high degree of risk involved in these investments can result in substantial or total losses. These securities are subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and a potential lack of a secondary or public market for securities. The market price of these securities can change suddenly and unexpectedly.

Tax Aware Investing Risk. The Fund's tax aware strategies may reduce your taxable income, but will not eliminate it. These strategies may require trade-offs that reduce pretax income. Managing the Fund to maximize after-tax returns may also potentially have a negative effect on the Fund's performance. Because tax consequences are considered in managing the Fund, the Fund's pre-tax performance may be lower than that of a similar fund that is not tax-managed.

Mortgage-Related and Other Asset-Backed Securities Risk. Mortgage-related and asset-backed securities, including certain municipal housing authority obligations, are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the assets underlying such securities. As a result, during periods of declining asset values, difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to prepayment and call risk. In periods of declining interest rates, the Fund may be subject to contraction risk which is the risk that borrowers will increase the rate at which they prepay the maturity value of mortgages and other obligations. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividend and yield. In periods of rising interest rates, the Fund may be subject to extension risk which is the risk that the expected maturity of an obligation will lengthen in duration due to a decrease in prepayments. As a result, in certain interest rate environments, the Fund may exhibit additional volatility. Collateralized mortgage obligations (CMOs), interest-only (IOs) and principal-only (POs) stripped mortgage-backed securities are more volatile and may be subject to a higher risk of non-payment than other mortgage related securities.

Short Selling Risk. The Fund may enter into short sales of certain securities and must borrow the securities to make delivery to the buyer. The Fund may not always be able to borrow a security it wants to sell short. The Fund also may be unable to close out an established short position at an acceptable price, and it may have to sell long positions at disadvantageous times to cover its short positions. In addition, the Fund may enter into short sales of instruments such as mortgage TBAs which do not involve borrowing a security. Furthermore, taking short positions in securities results in a form of leverage. Leverage involves special risks described under "Derivatives Risk." The Fund's loss on a short sale is potentially unlimited because there is no upward limit on the price a borrowed security could attain.

Taxability Risk. The Fund's investments in municipal securities rely on the opinion of the issuer's bond counsel that the interest paid on those securities will not be subject to federal income tax. Tax opinions are generally provided at the time the municipal security is initially issued. However, after the Fund buys a security, the Internal Revenue Service may determine that a bond issued as tax-exempt should in fact be taxable and the Fund's dividends with respect to that bond might be subject to federal income tax.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund's performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Repurchase Agreement Risk. Repurchase agreements involve some risk to the Fund that the counterparty does not meet its obligation under the agreement.

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.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class R6 Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years and ten years. The table compares that performance to the Bloomberg Barclays U.S. 1–15 Year Blend (1–17) Municipal Bond Index, the Tax Aware Real Return Composite Benchmark, a composite benchmark which is comprised of unmanaged indexes that correspond to the Fund’s objective of after-tax inflation protected return, and the Lipper Intermediate Municipal Debt Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other indexes, the Lipper index includes the fees and expenses of the mutual funds included in the index. The performance of Class R6 Shares is based on the performance of Institutional Class Shares of the Fund prior to the inception of Class R6 Shares. The actual returns of Class R6 Shares would have been different than those shown because Class R6 Shares have different expenses than Institutional Class Shares. Prior class performance for Class R6 Shares has been adjusted to reflect differences in expenses between Class R6 Shares and Institutional Shares. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

The Fund may engage in short sales including short sales of forward commitments. The Fund may also invest in repurchase agreements.

The average weighted maturity of the Fund's portfolio will be between three and ten years. Average weighted maturity is the average of all the current maturities (that is, the term of the securities) of the individual bonds in a Fund calculated so as to count most heavily those securities with the highest dollar value. Average weighted maturity is important to investors as an indication of a Fund's sensitivity to changes in interest rates. Usually, the longer the average weighted maturity, the more fluctuation in share price you can expect.

The Fund will invest primarily in securities that, at the time of purchase, are rated as investment grade by Moody's Investors Service Inc. (Moody's), Standard & Poor's Corporation (S&P), or Fitch Rating (Fitch), meaning that such securities will carry a minimum rating of Baa3, BBB–, or BBB–, respectively or the equivalent by another national rating organization, or are unrated but deemed by the adviser to be of comparable quality. No more than 10% of total assets may be invested in securities below investment grade (also known as junk bonds).

A "junk bond" is a debt security that is rated below investment grade. Junk bonds also include unrated securities that the adviser believes to be of comparable quality to debt securities that are rated below investment grade. Junk bonds are also called "high yield bonds" and "non-investment grade bonds." These securities generally are rated in the fifth or lower rating categories (for example, BB+ or lower by S&P and Ba1 or lower by Moody's). These securities generally offer a higher yield than investment grade securities, but involve a high degree of risk. A security's quality is determined at the time of purchase and securities that are rated investment grade or the unrated equivalent may be downgraded or decline in credit quality such that subsequently they would be deemed to be below investment grade. If the quality of an investment grade security is downgraded subsequent to purchase to below investment grade, the Fund may continue to hold the security.

The Fund seeks to minimize shareholders' tax liability in connection with the Fund's distribution of realized capital gain by minimizing the net gains available for distribution. As part of its tax aware strategy, the Fund typically sells securities when the anticipated performance benefit justifies the resulting gain. This strategy often includes minimizing the sale of securities with large unrealized gain, holding securities long enough to avoid short-term capital gains taxes, selling securities with a higher cost basis first and offsetting capital gains realized in one security by selling another security at a capital loss. In addition, the Fund seeks to minimize distributions that are taxed as ordinary income.

Investment Process: The adviser buys and sells securities and investments for the Fund based on its view of individual securities and sectors. Taking a long-term approach, the adviser looks for individual fixed income investments that it believes will perform well over market cycles. The adviser is value oriented and makes decisions to purchase and sell individual securities and instruments after performing a risk/reward analysis that includes an evaluation of interest rate risk, credit risk, duration, liquidity and the complex legal and technical structure of the transaction.

The frequency with which the Fund buys and sells securities will vary from year to year, depending on market conditions and the implementation of the tax aware strategy.

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 instruments 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund's performance and ability to meet its investment objective.

Municipal Obligations Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Changes in a municipality's financial health may make it difficult for the municipality to make interest and principal payments when due. This could decrease the Fund's income or hurt its ability to preserve capital and liquidity. Under some circumstances, municipal obligations might not pay interest unless the state legislature or municipality authorizes money for that purpose.

Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. In addition, since some municipal obligations may be secured or guaranteed by banks and other institutions, the risk to the Fund could increase if the banking or financial sector suffers an economic downturn and/or if the credit ratings of the institutions issuing the guarantee are downgraded or at risk of being downgraded by a national rating organization. Such a downward revision or risk of being downgraded may have an adverse effect on the market prices of the bonds and thus the value of the Fund's investments.

In addition to being downgraded, an insolvent municipality may file for bankruptcy. The reorganization of a municipality's debts may significantly affect the rights of creditors and the value of the securities issued by the municipality and the value of the Fund's investments. Interest on municipal obligations, while generally exempt from federal income tax, may not be exempt from federal alternative minimum tax.

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. Securities in the Fund's portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares' values may fluctuate in response to events affecting that industry or sector.

Derivatives Risk. Derivatives, including swaps, 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 expose the Fund to counterparty risk which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). 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.

In addition to risks associated with derivatives in general, the Fund will also be subject to risks related to swap agreements. 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.

Strategy Risk. The Fund's investments may not work to achieve the Fund's objective. There is no guarantee that the use of derivatives and debt securities will mimic a portfolio of inflation-protected municipal securities.

Inflation-Linked Securities Risk. Inflation-linked securities, including CPI-U swaps, are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general the price of an inflation-linked security tends to decline when real interest rates increase. Unlike conventional bonds, the principal or interest of inflation-linked securities such as TIPS is adjusted periodically to a specified rate of inflation (e.g., CPI-U). There can be no assurance that the inflation index used will accurately measure the real rate of inflation. These securities may lose value in the event that the actual rate of inflation is different than the rate of the inflation index.

Debt Securities and Other Callable Securities Risk. As part of its investment strategy, the Fund invests in debt securities. The issuers of these securities and other callable securities may be able to repay principal in advance, especially when interest rates fall. Changes in prepayment rates can affect the return on investment and yield of these securities. When debt obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield. The Fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss.

Government Securities Risk. The Fund invests in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. 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 will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

Interest Rate Risk. The Fund's investments in bonds and other debt securities will change in value based on changes in interest rates. If rates rise, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Given the historically low interest rate environment, risks associated with rising rates are heightened.

Credit Risk. The Fund's investments are subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund's investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund's securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer's securities.

High Yield Securities Risk. The Fund may invest in high yield, high risk securities (also known as junk bonds) which are considered to be speculative. These investments may be issued by companies which are highly leveraged, less creditworthy or financially distressed. Although these investments generally provide a higher yield than higher-rated debt securities, the high degree of risk involved in these investments can result in substantial or total losses. These securities are subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and a potential lack of a secondary or public market for securities. The market price of these securities can change suddenly and unexpectedly.

Tax Aware Investing Risk. The Fund's tax aware strategies may reduce your taxable income, but will not eliminate it. These strategies may require trade-offs that reduce pretax income. Managing the Fund to maximize after-tax returns may also potentially have a negative effect on the Fund's performance. Because tax consequences are considered in managing the Fund, the Fund's pre-tax performance may be lower than that of a similar fund that is not tax-managed.

Mortgage-Related and Other Asset-Backed Securities Risk. Mortgage-related and asset-backed securities, including certain municipal housing authority obligations, are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the assets underlying such securities. As a result, during periods of declining asset values, difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to prepayment and call risk. In periods of declining interest rates, the Fund may be subject to contraction risk which is the risk that borrowers will increase the rate at which they prepay the maturity value of mortgages and other obligations. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividend and yield. In periods of rising interest rates, the Fund may be subject to extension risk which is the risk that the expected maturity of an obligation will lengthen in duration due to a decrease in prepayments. As a result, in certain interest rate environments, the Fund may exhibit additional volatility. Collateralized mortgage obligations (CMOs), interest-only (IOs) and principal-only (POs) stripped mortgage-backed securities are more volatile and may be subject to a higher risk of non-payment than other mortgage related securities.

Short Selling Risk. The Fund may enter into short sales of certain securities and must borrow the securities to make delivery to the buyer. The Fund may not always be able to borrow a security it wants to sell short. The Fund also may be unable to close out an established short position at an acceptable price, and it may have to sell long positions at disadvantageous times to cover its short positions. In addition, the Fund may enter into short sales of instruments such as mortgage TBAs which do not involve borrowing a security. Furthermore, taking short positions in securities results in a form of leverage. Leverage involves special risks described under "Derivatives Risk." The Fund's loss on a short sale is potentially unlimited because there is no upward limit on the price a borrowed security could attain.

Taxability Risk. The Fund's investments in municipal securities rely on the opinion of the issuer's bond counsel that the interest paid on those securities will not be subject to federal income tax. Tax opinions are generally provided at the time the municipal security is initially issued. However, after the Fund buys a security, the Internal Revenue Service may determine that a bond issued as tax-exempt should in fact be taxable and the Fund's dividends with respect to that bond might be subject to federal income tax.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund's performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Repurchase Agreement Risk. Repurchase agreements involve some risk to the Fund that the counterparty does not meet its obligation under the agreement.

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class R6 Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years and ten years. The table compares that performance to the Bloomberg Barclays U.S. 1–15 Year Blend (1–17) Municipal Bond Index, the Tax Aware Real Return Composite Benchmark, a composite benchmark which is comprised of unmanaged indexes that correspond to the Fund’s objective of after-tax inflation protected return, and the Lipper Intermediate Municipal Debt Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other indexes, the Lipper index includes the fees and expenses of the mutual funds included in the index. The performance of Class R6 Shares is based on the performance of Institutional Class Shares of the Fund prior to the inception of Class R6 Shares. The actual returns of Class R6 Shares would have been different than those shown because Class R6 Shares have different expenses than Institutional Class Shares. Prior class performance for Class R6 Shares has been adjusted to reflect differences in expenses between Class R6 Shares and Institutional Shares. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

SMA Shares | JPMorgan International Value SMA Fund

JPMorgan International Value SMA Fund

Ticker: JTIVX

What is the goal of the Fund?

The Fund seeks to provide high total return from a portfolio of foreign company equity securities.

Fees and Expenses of the Fund

The following table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. You should be aware that, as shown under “Management Fees” in the table below, the Fund pays no fees under its advisory agreement to the Fund’s adviser. However, Fund shareholders are all participants in separately managed account programs and pay fees to program sponsors for costs and expenses of the programs, including fees for investment advice.

ANNUAL FUND OPERATING EXPENSES
(Expenses that you pay each year as a percentage of the
value of your investment)

Annual Fund Operating Expenses	SMA Shares JPMorgan International Value SMA Fund SMA
Management Fees	none
Distribution (Rule 12b-1) Fees	none
Other Expenses	0.32%
Shareholder Service Fees	none
Remainder of Other Expenses	0.32%	[1]
Total Annual Fund Operating Expenses	0.32%
Fee Waivers and Expense Reimbursements	(0.32%)	[2]
Total Annual Fund Operating Expenses After Fee Waivers and Expense Reimbursements	none	[2]

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. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 2/28/18 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

WHETHER OR NOT YOU SELL YOUR SHARES, YOUR

WHETHER OR NOT YOU SELL YOUR SHARES, YOUR
COST WOULD BE:

Expense Example, No Redemption	1 Year	3 Years	5 Years	10 Years
SMA Shares | JPMorgan International Value SMA Fund | SMA | USD ($)		70	148	374

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. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 70% of the average value of its portfolio.

What are the Fund’s main investment strategies?

The Fund is offered as a component of the JPMorgan International Value SMA Managed Account Strategy (“SMA Strategy”) to participants in separately managed account programs. As a result, the Fund’s holdings will depend on whether a particular security or instrument can be purchased directly on behalf of the participants in the separately managed account programs investing in the SMA Strategy. “International Value” in the Fund’s name is used to identify the Fund as a component of the SMA Strategy. The Fund is intended to be used as part of the SMA Strategy and not as a stand-alone international value strategy.

The Fund invests primarily in equity securities from developed countries included in the Morgan Stanley Capital International (MSCI) Europe, Australasia and Far East (EAFE) Value Index (net of foreign withholding taxes), which is the Fund’s benchmark. The Fund typically does not invest in U.S. companies.

Equity securities in which the Fund invests are common stocks, preferred stocks, convertible securities, depositary receipts, rights and warrants to buy common stocks and privately placed securities.

The Fund’s sector weightings generally approximate those of the MSCI EAFE Value Index, although the Fund does not seek to mirror the index in its choice of individual securities. In choosing securities, the Fund emphasizes those that are ranked as undervalued according to the proprietary research of the adviser while underweighting or avoiding those that appear overvalued.

The Fund may invest in securities denominated in U.S. dollars, other major reserve currencies, such as the euro, yen and pound sterling, and currencies of other countries in which it can invest.

The Fund may invest in securities across all market capitalizations, although the Fund may invest a significant portion of its assets in companies of any one particular market capitalization category.

The Fund may utilize currency forwards to reduce currency deviations, where practical, for the purpose of risk management. The Fund may also use exchange-traded futures for the efficient management of cash flows.

Investment Process: In managing the Fund, the adviser employs a process that combines fundamental research for identifying portfolio securities and currency management decisions.

Various models are used to quantify the adviser’s fundamental stock research, producing a ranking of companies in each industry group according to their relative value. The Fund’s management team then buys and sells securities, using the research and valuation rankings as well as its assessment of other factors, including:

• value characteristics such as low price-to-book and price-to-earnings ratios;

• catalysts that could trigger a change in a security’s price;

• potential reward compared to potential risk; and

• temporary mispricings caused by market overreactions.

The Fund has access to the adviser’s currency specialists in determining the extent and nature of the Fund’s exposure to various foreign currencies.

The Fund may invest a substantial part of its assets in just one region or country.

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 instruments or markets are not met. Because the Fund is managed as a component of the SMA Strategy, the Fund is subject to the risks associated with the particular securities and instruments that it holds, which may be more pronounced than those associated with the SMA Strategy or with other mutual funds that have similar strategies.

Because the Fund is offered as a component of the SMA Strategy to participants in separately managed account programs, it is designed to complement the investments purchased directly on behalf of participants in the separately managed account programs invested in the SMA Strategy. Therefore, the Fund represents only a portion of the overall SMA Strategy. 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

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. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

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. Securities in the Fund’s portfolio may underperform securities in comparison to general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, regulatory events and government controls.

Foreign Securities and Emerging Markets 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, sanctions or other measures by the United States or other governments, 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 or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely.

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. These risks are magnified in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. Emerging market countries typically have less-established economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

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.

Geographic Focus Risk. The Fund may focus its investments in one or more regions or small groups of countries. As a result, the Fund’s performance may be subject to greater volatility than a more geographically diversified fund.

Depositary Receipt Risk. The Fund’s investments may take the form of depositary receipts, including unsponsored depositary receipts. Unsponsored depositary receipts may not provide as much information about the underlying issuer and may not carry the same voting privileges as sponsored depositary receipts. Unsponsored depositary receipts are issued by one or more depositaries in response to market demand, but without a formal agreement with the company that issues the underlying securities.

Smaller Company Risk. Investments in securities of smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than securities of larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Derivatives Risk. Derivatives, including forward currency contracts and futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including the credit risk of the derivative counterparty. 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.

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 impacted by that currency loses value because that currency is worth less in U.S. dollars. Currency exchange rates may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates. 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. Although the Fund may attempt to hedge its currency exposure into the U.S. dollar, it may not be successful in reducing 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.

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. However, the Fund does not typically use this hedging strategy for its emerging markets currency exposure.

Credit Risk. The Fund’s investments are subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

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.

Real Estate Securities Risk. The Fund’s investments in real estate securities 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 issuers.

High Portfolio Turnover Risk. The Fund may 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.

Industry and Sector Focus Risk. At times, the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

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.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Shares has varied from year to year over the past nine calendar years. The table shows the average annual total returns over the past one year, five years and life of the Fund. The table compares that performance to the Morgan Stanley Capital International (MSCI), Europe, Australasia and Far East (EAFE) Value Index (net of foreign withholding taxes), and the Lipper International Large-Cap Value Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the fees and expenses of the mutual funds included in the average. The Fund’s performance information does not reflect fees paid to separately managed account program sponsors by participants. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on the investor’s tax situation and may differ from those shown, and the after-tax returns shown are not relevant to investors who hold their shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

[1] "Remainder of Other Expenses" has been calculated based on the actual other expenses incurred in the most recent fiscal year, except that these expenses have been adjusted to reflect the elimination of sub-transfer fees paid directly by the Fund effective 4/3/17.

[2] The Fund's adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding acquired fund fees and expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, and extraordinary expenses) exceed 0.00% of the average daily net assets of Shares. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund's adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund's investment in such money market funds. These waivers are in effect through 2/28/18, at which time the adviser and/ or its affiliates will determine whether to renew or revise them.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is offered as a component of the JPMorgan International Value SMA Managed Account Strategy (“SMA Strategy”) to participants in separately managed account programs. As a result, the Fund’s holdings will depend on whether a particular security or instrument can be purchased directly on behalf of the participants in the separately managed account programs investing in the SMA Strategy. “International Value” in the Fund’s name is used to identify the Fund as a component of the SMA Strategy. The Fund is intended to be used as part of the SMA Strategy and not as a stand-alone international value strategy.

The Fund invests primarily in equity securities from developed countries included in the Morgan Stanley Capital International (MSCI) Europe, Australasia and Far East (EAFE) Value Index (net of foreign withholding taxes), which is the Fund’s benchmark. The Fund typically does not invest in U.S. companies.

Equity securities in which the Fund invests are common stocks, preferred stocks, convertible securities, depositary receipts, rights and warrants to buy common stocks and privately placed securities.

The Fund’s sector weightings generally approximate those of the MSCI EAFE Value Index, although the Fund does not seek to mirror the index in its choice of individual securities. In choosing securities, the Fund emphasizes those that are ranked as undervalued according to the proprietary research of the adviser while underweighting or avoiding those that appear overvalued.

The Fund may invest in securities denominated in U.S. dollars, other major reserve currencies, such as the euro, yen and pound sterling, and currencies of other countries in which it can invest.

The Fund may invest in securities across all market capitalizations, although the Fund may invest a significant portion of its assets in companies of any one particular market capitalization category.

The Fund may utilize currency forwards to reduce currency deviations, where practical, for the purpose of risk management. The Fund may also use exchange-traded futures for the efficient management of cash flows.

Investment Process: In managing the Fund, the adviser employs a process that combines fundamental research for identifying portfolio securities and currency management decisions.

Various models are used to quantify the adviser’s fundamental stock research, producing a ranking of companies in each industry group according to their relative value. The Fund’s management team then buys and sells securities, using the research and valuation rankings as well as its assessment of other factors, including:

• value characteristics such as low price-to-book and price-to-earnings ratios;

• catalysts that could trigger a change in a security’s price;

• potential reward compared to potential risk; and

• temporary mispricings caused by market overreactions.

The Fund has access to the adviser’s currency specialists in determining the extent and nature of the Fund’s exposure to various foreign currencies.

The Fund may invest a substantial part of its assets in just one region or country.

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 instruments or markets are not met. Because the Fund is managed as a component of the SMA Strategy, the Fund is subject to the risks associated with the particular securities and instruments that it holds, which may be more pronounced than those associated with the SMA Strategy or with other mutual funds that have similar strategies.

Because the Fund is offered as a component of the SMA Strategy to participants in separately managed account programs, it is designed to complement the investments purchased directly on behalf of participants in the separately managed account programs invested in the SMA Strategy. Therefore, the Fund represents only a portion of the overall SMA Strategy. 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

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. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

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. Securities in the Fund’s portfolio may underperform securities in comparison to general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, regulatory events and government controls.

Foreign Securities and Emerging Markets 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, sanctions or other measures by the United States or other governments, 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 or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely.

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. These risks are magnified in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. Emerging market countries typically have less-established economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

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.

Geographic Focus Risk. The Fund may focus its investments in one or more regions or small groups of countries. As a result, the Fund’s performance may be subject to greater volatility than a more geographically diversified fund.

Depositary Receipt Risk. The Fund’s investments may take the form of depositary receipts, including unsponsored depositary receipts. Unsponsored depositary receipts may not provide as much information about the underlying issuer and may not carry the same voting privileges as sponsored depositary receipts. Unsponsored depositary receipts are issued by one or more depositaries in response to market demand, but without a formal agreement with the company that issues the underlying securities.

Smaller Company Risk. Investments in securities of smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than securities of larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of debt or equity issued by such companies may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Derivatives Risk. Derivatives, including forward currency contracts and futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including the credit risk of the derivative counterparty. 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.

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 impacted by that currency loses value because that currency is worth less in U.S. dollars. Currency exchange rates may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates. 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. Although the Fund may attempt to hedge its currency exposure into the U.S. dollar, it may not be successful in reducing 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.

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. However, the Fund does not typically use this hedging strategy for its emerging markets currency exposure.

Credit Risk. The Fund’s investments are subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

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.

Real Estate Securities Risk. The Fund’s investments in real estate securities 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 issuers.

High Portfolio Turnover Risk. The Fund may 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.

Industry and Sector Focus Risk. At times, the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

SMA Shares | JPMorgan Tax Aware Real Return SMA Fund

JPMorgan Tax Aware Real Return SMA Fund

Ticker: JTARX

What is the goal of the Fund?

The Fund seeks to maximize after-tax inflation protected return.

Fees and Expenses of the Fund

The following table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. As shown under “Management Fees” in the table below, the Fund pays no fees under its advisory agreement to the Fund’s adviser. However, Fund shareholders are all participants in separately managed account programs and pay fees to program sponsors for costs and expenses of the programs, including fees for investment advice.

“Acquired Fund Fees and Expenses” are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies, including affiliated money market funds, other mutual funds, exchange-traded funds and business development companies. The impact of Acquired Fund Fees and Expenses is included in the total returns of the Fund. Acquired Fund Fees and Expenses are not direct costs of the Fund, are not used to calculate the Fund’s net asset value per share and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus.

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. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was less than 32% of the average value of its portfolio.

What are the Fund’s main investment strategies?

The Fund is offered as a component of the Tax Aware Real Return SMA Managed Account Strategy ("SMA Strategy") to participants in separately managed account programs. As a result, the Fund's holdings will consist primarily of those securities or instruments which cannot be easily purchased directly on behalf of the participants in the separately managed account programs investing in the SMA Strategy. Since the Fund will be used as part of a SMA Strategy, it is not intended to be a stand-alone municipal investment strategy.

The Fund is designed to protect after-tax return by, under normal circumstances, primarily investing in a portfolio of municipal obligations whose interest payments are excluded from federal income taxes. The Fund is also designed to maximize inflation-protected return, which means maximizing the "real return." Real Return is the total return of a security less the actual rate of inflation. Because of the limited supply of inflation-protected municipal securities, the Fund seeks to synthetically create inflation protection by investing in a combination of conventional (i.e., non-inflation protected) municipal securities and inflation-linked derivatives such as Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U) swaps. The adviser may use other strategies to achieve the Fund's objective including investments in other types of securities which provide after-tax return and direct investments in inflation-linked securities such as Treasury Inflation Protected Securities (TIPS) and municipal inflation-linked securities, if available.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may also be used as substitutes for securities in which the Fund will invest. As part of its principal investment strategy, the Fund may invest substantially in swaps in which the Fund receives inflation-linked payments that provide inflation protection.

The Fund also may invest in taxable debt securities, including but not limited to asset-backed and mortgage-related securities, U.S. government and agency securities, domestic corporate bonds and money market instruments and repurchase agreements. The Fund may engage in short sales including short sales of forward commitments. The Fund may also invest in repurchase agreements.

The average weighted maturity of the Fund's portfolio will be between three and ten years. Average weighted maturity is the average of all the current maturities (that is, the term of the securities) of the individual bonds in a Fund calculated so as to count most heavily those securities with the highest dollar value. Average weighted maturity is important to investors as an indication of a Fund's sensitivity to changes in interest rates. Usually, the longer the average weighted maturity, the more fluctuation in share price you can expect.

The Fund will invest primarily in securities that, at the time of purchase, are rated as investment grade by Moody's Investors Service Inc. (Moody's), Standard & Poor's Corporation (S&P), or Fitch Rating (Fitch), meaning that such securities will carry a minimum rating of Baa3, BBB–, or BBB–, respectively or the equivalent by another national rating organization, or are unrated but deemed by the adviser to be of comparable quality. No more than 10% of total assets may be invested in securities below investment grade (also known as junk bonds). A "junk bond" is a debt security that is rated below investment grade. Junk bonds also include unrated securities that the adviser believes to be of comparable quality to debt securities that are rated below investment grade. Junk bonds are also called "high yield bonds" and "non-investment grade bonds." These securities generally are rated in the fifth or lower rating categories (for example, BB+ or lower by S&P and Ba1 or lower by Moody's). These securities generally offer a higher yield than investment grade securities, but involve a high degree of risk. A security's quality is determined at the time of purchase and securities that are rated investment grade or the unrated equivalent may be downgraded or decline in credit quality such that subsequently they would be deemed to be below investment grade. If the quality of an investment grade security is downgraded subsequent to purchase to below investment grade, the Fund may continue to hold the security.

The Fund seeks to minimize shareholders' tax liability in connection with the Fund's distribution of realized capital gain by minimizing the net gains available for distribution. As part of its tax aware strategy, the Fund typically sells securities when the anticipated performance benefit justifies the resulting gain. This strategy often includes minimizing the sale of securities with large unrealized gain, holding securities long enough to avoid short-term capital gains taxes, selling securities with a higher cost basis first and offsetting capital gains realized in one security by selling another security at a capital loss. In addition, the Fund seeks to minimize distributions that are taxed as ordinary income.

Investment Process: The adviser buys and sells securities and investments for the Fund based on its view of individual securities and sectors. Taking a long-term approach, the adviser looks for individual fixed income investments that it believes will perform well over market cycles. The adviser is value oriented and makes decisions to purchase and sell individual securities and instruments after performing a risk/reward analysis that includes an evaluation of interest rate risk, credit risk, duration, liquidity and the legal and technical structure of the transaction.

The frequency with which the Fund buys and sells securities will vary from year to year, depending on market conditions and the implementation of the tax aware strategy.

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 instruments or markets are not met. Because the Fund is managed as a component of the SMA Strategy, the Fund is subject to the risks associated with the particular securities and instruments that it holds, which may be more pronounced than those associated with the SMA Strategy or with other mutual funds that have similar strategies.

Because the Fund is offered as a component of the SMA Strategy to participants in separately managed account programs, it is designed to complement the investments purchased directly on behalf of participants in the separately managed account programs invested in the SMA Strategy. Therefore, the Fund represents only a portion of the overall SMA Strategy. 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund's performance and ability to meet its investment objective.

Municipal Obligations Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Changes in a municipality's financial health may make it difficult for the municipality to make interest and principal payments when due. This could decrease the Fund's income or hurt its ability to preserve capital and liquidity. Under some circumstances, municipal obligations might not pay interest unless the state legislature or municipality authorizes money for that purpose.

Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. In addition, since some municipal obligations may be secured or guaranteed by banks and other institutions, the risk to the Fund could increase if the banking or financial sector suffers an economic downturn and/or if the credit ratings of the institutions issuing the guarantee are downgraded or at risk of being downgraded by a national rating organization. Such a downward revision or risk of being downgraded may have an adverse effect on the market prices of the bonds and thus the value of the Fund's investments.

In addition to being downgraded, an insolvent municipality may file for bankruptcy. The reorganization of a municipality's debts may significantly affect the rights of creditors and the value of the securities issued by the municipality and the value of the Fund's investments. Interest on municipal obligations, while generally exempt from federal income tax, may not be exempt from federal alternative minimum tax.

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. Securities in the Fund's portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares' values may fluctuate in response to events affecting that industry or sector.

Derivatives Risk. Derivatives, including swaps, 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 expose the Fund to counterparty risk which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes the credit risk associated with the counterparty.) 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.

In addition to risks associated with derivatives in general, the Fund will also be subject to risks related to swap agreements. 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.

Strategy Risk. The Fund's investments may not work to achieve the Fund's objective. There is no guarantee that the use of derivatives and debt securities will mimic a portfolio of inflation-protected municipal securities.

Inflation-Linked Securities Risk. Inflation-linked securities, including CPI-U swaps, are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of an inflation-linked security tends to decline when real interest rates increase. Unlike conventional bonds, the principal or interest of inflation-linked securities such as TIPS is adjusted periodically to a specified rate of inflation (e.g., CPI-U). There can be no assurance that the inflation index used will accurately measure the real rate of inflation. These securities may lose value in the event that the actual rate of inflation is different than the rate of the inflation index.

Debt Securities and Other Callable Securities Risk. As part of its investment strategy, the Fund invests in debt securities. The issuers of these securities and other callable securities may be able to repay principal in advance, especially when interest rates fall. Changes in prepayment rates can affect the return on investment and yield of these securities. When debt obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield. The Fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss.

Government Securities Risk. The Fund invests in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. 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 will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

Interest Rate Risk. The Fund's investments in bonds and other debt securities will change in value based on changes in interest rates. If rates rise, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Given the historically low interest rate environment, risks associated with rising rates are heightened.

Credit Risk. The Fund's investments are subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund's investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund's securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer's securities.

High Yield Securities Risk. The Fund may invest in high yield, high risk securities (also known as junk bonds) which are considered to be speculative. These investments may be issued by companies which are highly leveraged, less creditworthy or financially distressed. Although these investments generally provide a higher yield than higher-rated debt securities, the high degree of risk involved in these investments can result in substantial or total losses. These securities are subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and a potential lack of a secondary or public market for securities. The market price of these securities can change suddenly and unexpectedly.

Tax Aware Investing Risk. The Fund's tax aware strategies may reduce your taxable income, but will not eliminate it. These strategies may require trade-offs that reduce pretax income. Managing the Fund to maximize after-tax returns may also potentially have a negative effect on the Fund's performance. Because tax consequences are considered in managing the Fund, the Fund's pre-tax performance may be lower than that of a similar fund that is not tax-managed.

Mortgage-Related and Other Asset-Backed Securities Risk. Mortgage-related and asset-backed securities, including certain municipal housing authority obligations, are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the assets underlying such securities. As a result, during periods of declining asset values, difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to prepayment and call risk. In periods of declining interest rates, the Fund may be subject to contraction risk which is the risk that borrowers will increase the rate at which they prepay the maturity value of mortgages and other obligations. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividend and yield. In periods of rising interest rates, the Fund may be subject to extension risk which is the risk that the expected maturity of an obligation will lengthen in duration due to a decrease in prepayments. As a result, in certain interest rate environments, the Fund may exhibit additional volatility. Collateralized mortgage obligations (CMOs), interest-only (IOs) and principal-only (POs) stripped mortgage-backed securities are more volatile and may be subject to a higher risk of non-payment than other mortgage related securities.

Short Selling Risk. The Fund may enter into short sales of certain securities and must borrow the securities to make delivery to the buyer. The Fund may not always be able to borrow a security it wants to sell short. The Fund also may be unable to close out an established short position at an acceptable price, and it may have to sell long positions at disadvantageous times to cover its short positions. In addition, the Fund may enter into short sales of instruments such as mortgage TBAs which do not involve borrowing a security. Furthermore, taking short positions in securities results in a form of leverage. Leverage involves special risks described under "Derivatives Risk." The Fund's loss on a short sale is potentially unlimited because there is no upward limit on the price a borrowed security could attain.

Taxability Risk. The Fund's investments in municipal securities rely on the opinion of the issuer's bond counsel that the interest paid on those securities will not be subject to federal income tax. Tax opinions are generally provided at the time the municipal security is initially issued. However, after the Fund buys a security, the Internal Revenue Service may determine that a bond issued as tax-exempt should in fact be taxable and the Fund's dividends with respect to that bond might be subject to federal income tax.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund's performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Repurchase Agreement Risk. Repurchase agreements involve some risk to the Fund that the counterparty does not meet its obligation under the agreement.

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.

(Moody's), Standard & Poor's Corporation (S&P), or Fitch Rating (Fitch), meaning that such securities will carry a minimum rating of Baa3, BBB–, or BBB–, respectively or the equivalent by another national rating organization, or are unrated but deemed by the adviser to be of comparable quality. No more than 10% of total assets may be invested in securities below investment grade (also known as junk bonds). A "junk bond" is a debt security that is rated below investment grade. Junk bonds also include unrated securities that the adviser believes to be of comparable quality to debt securities that are rated below investment grade. Junk bonds are also called "high yield bonds" and "non-investment grade bonds." These securities generally are rated in the fifth or lower rating categories (for example, BB+ or lower by S&P and Ba1 or lower by Moody's). These securities generally offer a higher yield than investment grade securities, but involve a high degree of risk. A security's quality is determined at the time of purchase and securities that are rated investment grade or the unrated equivalent may be downgraded or decline in credit quality such that subsequently they would be deemed to be below investment grade. If the quality of an investment grade security is downgraded subsequent to purchase to below investment grade, the Fund may continue to hold the security.

The Fund seeks to minimize shareholders' tax liability in connection with the Fund's distribution of realized capital gain by minimizing the net gains available for distribution. As part of its tax aware strategy, the Fund typically sells securities when the anticipated performance benefit justifies the resulting gain. This strategy often includes minimizing the sale of securities with large unrealized gain, holding securities long enough to avoid short-term capital gains taxes, selling securities with a higher cost basis first and offsetting capital gains realized in one security by selling another security at a capital loss. In addition, the Fund seeks to minimize distributions that are taxed as ordinary income.

Investment Process: The adviser buys and sells securities and investments for the Fund based on its view of individual securities and sectors. Taking a long-term approach, the adviser looks for individual fixed income investments that it believes will perform well over market cycles. The adviser is value oriented and makes decisions to purchase and sell individual securities and instruments after performing a risk/reward analysis that includes an evaluation of interest rate risk, credit risk, duration, liquidity and the legal and technical structure of the transaction.

The frequency with which the Fund buys and sells securities will vary from year to year, depending on market conditions and the implementation of the tax aware strategy.

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 instruments or markets are not met. Because the Fund is managed as a component of the SMA Strategy, the Fund is subject to the risks associated with the particular securities and instruments that it holds, which may be more pronounced than those associated with the SMA Strategy or with other mutual funds that have similar strategies.

Because the Fund is offered as a component of the SMA Strategy to participants in separately managed account programs, it is designed to complement the investments purchased directly on behalf of participants in the separately managed account programs invested in the SMA Strategy. Therefore, the Fund represents only a portion of the overall SMA Strategy. 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund's performance and ability to meet its investment objective.

Municipal Obligations Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Changes in a municipality's financial health may make it difficult for the municipality to make interest and principal payments when due. This could decrease the Fund's income or hurt its ability to preserve capital and liquidity. Under some circumstances, municipal obligations might not pay interest unless the state legislature or municipality authorizes money for that purpose.

Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. In addition, since some municipal obligations may be secured or guaranteed by banks and other institutions, the risk to the Fund could increase if the banking or financial sector suffers an economic downturn and/or if the credit ratings of the institutions issuing the guarantee are downgraded or at risk of being downgraded by a national rating organization. Such a downward revision or risk of being downgraded may have an adverse effect on the market prices of the bonds and thus the value of the Fund's investments.

In addition to being downgraded, an insolvent municipality may file for bankruptcy. The reorganization of a municipality's debts may significantly affect the rights of creditors and the value of the securities issued by the municipality and the value of the Fund's investments. Interest on municipal obligations, while generally exempt from federal income tax, may not be exempt from federal alternative minimum tax.

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. Securities in the Fund's portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares' values may fluctuate in response to events affecting that industry or sector.

Derivatives Risk. Derivatives, including swaps, 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 expose the Fund to counterparty risk which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes the credit risk associated with the counterparty.) 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.

In addition to risks associated with derivatives in general, the Fund will also be subject to risks related to swap agreements. 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.

Strategy Risk. The Fund's investments may not work to achieve the Fund's objective. There is no guarantee that the use of derivatives and debt securities will mimic a portfolio of inflation-protected municipal securities.

Inflation-Linked Securities Risk. Inflation-linked securities, including CPI-U swaps, are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of an inflation-linked security tends to decline when real interest rates increase. Unlike conventional bonds, the principal or interest of inflation-linked securities such as TIPS is adjusted periodically to a specified rate of inflation (e.g., CPI-U). There can be no assurance that the inflation index used will accurately measure the real rate of inflation. These securities may lose value in the event that the actual rate of inflation is different than the rate of the inflation index.

Debt Securities and Other Callable Securities Risk. As part of its investment strategy, the Fund invests in debt securities. The issuers of these securities and other callable securities may be able to repay principal in advance, especially when interest rates fall. Changes in prepayment rates can affect the return on investment and yield of these securities. When debt obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield. The Fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss.

Government Securities Risk. The Fund invests in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. 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 will provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

Interest Rate Risk. The Fund's investments in bonds and other debt securities will change in value based on changes in interest rates. If rates rise, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Given the historically low interest rate environment, risks associated with rising rates are heightened.

Credit Risk. The Fund's investments are subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Fund's investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund's securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer's securities.

High Yield Securities Risk. The Fund may invest in high yield, high risk securities (also known as junk bonds) which are considered to be speculative. These investments may be issued by companies which are highly leveraged, less creditworthy or financially distressed. Although these investments generally provide a higher yield than higher-rated debt securities, the high degree of risk involved in these investments can result in substantial or total losses. These securities are subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and a potential lack of a secondary or public market for securities. The market price of these securities can change suddenly and unexpectedly.

Tax Aware Investing Risk. The Fund's tax aware strategies may reduce your taxable income, but will not eliminate it. These strategies may require trade-offs that reduce pretax income. Managing the Fund to maximize after-tax returns may also potentially have a negative effect on the Fund's performance. Because tax consequences are considered in managing the Fund, the Fund's pre-tax performance may be lower than that of a similar fund that is not tax-managed.

Mortgage-Related and Other Asset-Backed Securities Risk. Mortgage-related and asset-backed securities, including certain municipal housing authority obligations, are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the assets underlying such securities. As a result, during periods of declining asset values, difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to prepayment and call risk. In periods of declining interest rates, the Fund may be subject to contraction risk which is the risk that borrowers will increase the rate at which they prepay the maturity value of mortgages and other obligations. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividend and yield. In periods of rising interest rates, the Fund may be subject to extension risk which is the risk that the expected maturity of an obligation will lengthen in duration due to a decrease in prepayments. As a result, in certain interest rate environments, the Fund may exhibit additional volatility. Collateralized mortgage obligations (CMOs), interest-only (IOs) and principal-only (POs) stripped mortgage-backed securities are more volatile and may be subject to a higher risk of non-payment than other mortgage related securities.

Short Selling Risk. The Fund may enter into short sales of certain securities and must borrow the securities to make delivery to the buyer. The Fund may not always be able to borrow a security it wants to sell short. The Fund also may be unable to close out an established short position at an acceptable price, and it may have to sell long positions at disadvantageous times to cover its short positions. In addition, the Fund may enter into short sales of instruments such as mortgage TBAs which do not involve borrowing a security. Furthermore, taking short positions in securities results in a form of leverage. Leverage involves special risks described under "Derivatives Risk." The Fund's loss on a short sale is potentially unlimited because there is no upward limit on the price a borrowed security could attain.

Taxability Risk. The Fund's investments in municipal securities rely on the opinion of the issuer's bond counsel that the interest paid on those securities will not be subject to federal income tax. Tax opinions are generally provided at the time the municipal security is initially issued. However, after the Fund buys a security, the Internal Revenue Service may determine that a bond issued as tax-exempt should in fact be taxable and the Fund's dividends with respect to that bond might be subject to federal income tax.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund's performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Repurchase Agreement Risk. Repurchase agreements involve some risk to the Fund that the counterparty does not meet its obligation under the agreement.

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. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 2/28/18 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

IF YOU SELL YOUR SHARES, YOUR COST WOULD BE:

Expense Example - A, C, Select Shares - JPMorgan Commodities Strategy Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	646	1,161	1,702	3,175
CLASS C SHARES	278	867	1,580	3,472
SELECT CLASS SHARES	102	566	1,057	2,411

IF YOU DO NOT SELL YOUR SHARES, YOUR COST
WOULD BE:

Expense Example, No Redemption - A, C, Select Shares - JPMorgan Commodities Strategy Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	646	1,161	1,702	3,175
CLASS C SHARES	178	867	1,580	3,472
SELECT CLASS SHARES	102	566	1,057	2,411

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. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 0% of the average value of its portfolio.

What are the Fund’s main investment strategies?

The Fund seeks to achieve its objective by investing in a diversified portfolio of commodity-linked derivatives. The Fund will also invest in fixed income securities.

Commodity Investments
The Fund invests in commodity-linked derivative instruments, such as commodity-linked notes, swap agreements, commodity options, futures and options on futures that provide exposure to the investment returns of the commodities markets without investing directly in physical commodities. Commodities are assets that have tangible properties, such as oil, metals, and agricultural products. Derivatives are instruments that have a value based on another instrument, exchange rate or index and will generally be used as substitutes for commodities.

The Fund will gain exposure to commodity markets by investing up to 25% of its total assets in the Commodities Strategy Fund CS Ltd., a wholly owned subsidiary of the Fund organized under the laws of the Cayman Islands (the Subsidiary). The Subsidiary is also advised by J.P. Morgan Investment Management Inc. (JPMIM or Adviser) and has the same investment objective as the Fund. The Subsidiary (unlike the Fund) may invest without limitation in commodity futures contracts, commodity-linked swap agreements and other commodity-linked derivative instruments, including derivative instruments linked to the value of a particular commodity, commodity index or commodity futures contract, or a subset of commodities or commodity futures contracts. However, the Subsidiary is otherwise subject to the same fundamental, non-fundamental and certain other investment restrictions as the Fund.

The Fund intends to provide long exposure to the commodities markets. In addition, the Subsidiary may use short positions in commodities to reduce exposure to the commodities market. Although the long and short positions held by the Subsidiary will vary in size as market opportunities change, the Fund intends to maintain a net exposure to the commodities market within a range of 70% to 130% of the value of the Fund’s net assets. The Subsidiary may use derivatives to obtain long or short exposure in an attempt to increase the Subsidiary’s income or gain, to hedge various investments and for risk management. In rising markets, the Fund expects that the value of the long positions will appreciate more rapidly than the short positions, and in declining markets, that the value of the short positions will appreciate more rapidly than the long positions.

The Fund’s or the Subsidiary’s investments in commodity-linked derivative instruments may deviate from the returns of any particular commodity index. The Fund or the Subsidiary may also overweight or underweight its exposure to a subset of commodities, such that the Fund has greater or lesser exposure to a subset of commodities than is represented by a particular commodity index.

Fixed Income Investments
Assets not invested in commodity-linked derivatives, currency-linked derivatives or the Subsidiary will be invested in high quality, short term fixed income securities. The fixed income portion of the Fund is intended to provide liquidity and preserve capital. The Fund’s fixed income securities may include: obligations of the U.S. Treasury, including Treasury bills, bonds and notes and other obligations issued or guaranteed by the U.S. Treasury; Treasury Inflation Protected Securities (TIPS); securities issued or guaranteed by the U.S. government, its agencies or instrumentalities; high quality commercial paper and other short-term debt securities, including floating and variable rate demand notes, of U.S. and foreign corporations; debt securities issued or guaranteed by U.S., foreign, and supranational banks, including certificates of deposit, time deposits and other short-term securities; repurchase agreements fully collateralized by U.S. Treasury and U.S. government securities; and corporate debt obligations. The Fund generally will only buy securities that have remaining maturities of 397 days or less. The dollar-weighted average maturity of the Fund’s fixed income investments will generally be 90 days or less. The Fund may also invest in affiliated money market funds.

The Subsidiary will also invest in fixed income securities, either as investments or to serve as margin or collateral for its derivative positions.

Investment Process:

JPMIM uses a global quarterly and weekly investment process that applies fundamental, quantitative, and technical analysis to develop investment themes in each commodity market. The process includes a global team of investors across markets and sectors. JPMIM utilizes the output of the global investment process to position the Fund’s exposure to the broader commodities market. JPMIM uses sector investment specialists to perform fundamental and quantitative analysis on each commodity and utilizes their inputs in its decision to over/underweight individual commodity holdings relative to the Fund’s benchmark. JPMIM seeks to enhance returns by using its analysis of each commodity to decide the time to delivery of each holding.

Fixed Income Investments Process
JPMIM seeks to develop an appropriate fixed income portfolio and buys and sells securities by considering the differences in yields among securities of different maturities, market sectors and issuers.

The frequency with which the Fund buys and sells securities will vary from year to year, depending on market conditions.

The Fund is non-diversified.

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 instruments 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

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. Securities in the Fund’s portfolio may underperform securities in comparison to general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Commodity Risk. Because the Fund will have a significant portion of its assets concentrated in commodity-linked securities, developments affecting commodities will have a disproportionate impact on the Fund. The Fund’s investment in commodity-linked derivative instruments may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked derivative instruments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. 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.

CFTC Regulation Risk. The Fund is subject to regulation by the Commodity Futures Trading Commission (CFTC) as a “commodity pool” and the Adviser is subject to regulation as a “commodity pool operator” with respect to the Fund. As a result, the Fund is subject to various CFTC requirements, including certain registration, disclosure and operational requirements. Compliance with these requirements may increase Fund expenses.

Derivatives Risk. Derivatives, including commodity-linked notes, swap agreements, commodity options, futures and options on futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations) and to the credit risk of the derivative counterparty. 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.

Swap Agreement Risk. In addition to the risks associated with derivatives in general, the Fund will also be subject to risks related to swap agreements. The Subsidiary may use swaps to establish both long and short positions in order to gain the desired exposure. The Fund’s losses are potentially unlimited in short sale positions. Short sales are speculative transactions and involve special risks, including greater reliance on the Adviser’s ability to accurately anticipate the future value of an instrument. 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.

Counterparty Risk. Commodity-linked derivatives, repurchase agreements, swap agreements and other forms of financial instruments that involve counterparties subject the Fund to the risk that the counterparty could default on its obligations under the agreement, either through the counterparty’s bankruptcy or failure to perform its obligations. In the event of default, the Fund could experience lengthy delays in recovering some or all of its assets or no recovery at all.

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 impacted by that currency loses value because that currency is worth less in U.S. dollars. Currency exchange rates may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates. 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. Although the Fund may attempt to hedge its currency exposure into the U.S. dollar, it may not be successful in reducing the effects of currency fluctuations. The Fund may also hedge from one foreign currency to another. 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.

Interest Rate Risk. The Fund’s investments in bonds and other debt securities will change in value based on changes in interest rates. If rates increase, the value of the Fund’s investments generally declines. On the other hand, if rates fall, the value of the investments generally increases. Your investment will decline in value if the value of the investments decreases. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Usually, the changes in the value of fixed income securities will not affect cash income generated, but may affect the value of your investment. Given the historically low interest rate environment, risks associated with rising rates are heightened.

Credit Risk. There is a risk that issuers and/or counterparties will not make payments on securities, repurchase agreements or other investments held by the Fund. Such defaults could result in losses to the Fund. In addition, the credit quality of securities held by the Fund may be lowered if an issuer’s or a counterparty’s financial condition changes. Lower credit quality may lead to greater volatility in the price of a security and in shares of the Fund. Lower credit quality also may affect liquidity and make it difficult for the Fund to sell the security. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Inflation-Linked Security Risk. Inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of an inflation-linked security tends to decrease when real interest rates increase and can increase when real interest rates decrease. Interest payments on inflation-linked securities are unpredictable and will fluctuate as the principal and interest are adjusted for inflation. Any increase in the principal amount of an inflation-linked debt security will be considered taxable ordinary income, even though the Fund will not receive the principal until maturity. There can also be no assurance that the inflation index used will accurately measure the real rate of inflation in the prices of goods and services. The Fund’s investments in inflation-linked securities may lose value in the event that the actual rate of inflation is different than the rate of the inflation index. In addition, inflation-linked securities are subject to the risk that the Consumer Price Index for all Urban Consumers (CPI-U) or other relevant pricing index may be discontinued, fundamentally altered in a manner materially adverse to the interests of an investor in the securities, altered by legislation or Executive Order in a materially adverse manner to the interests of an investor in the securities or substituted with an alternative index.

Government Securities Risk. The Fund invests in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac)).

U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. 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 will provide financial support. Therefore, U.S. government related organizations may not have the funds to meet their payment obligations in the future.

Tax Risk. The Fund gains exposure to the commodities markets through investments in commodity-linked derivative instruments, including commodity index-linked notes, swap agreements, commodity options, futures, and options on futures. The Fund intends to gain exposure indirectly to commodity markets by investing in its Subsidiary, which invests primarily in commodity-linked derivative instruments. In order for the Fund to qualify as a regulated investment company under Subchapter M of Internal Revenue Code, as amended (the Code), the Fund must derive at least 90 percent of its gross income each taxable year from certain qualifying sources of income. The Fund’s intention to qualify as a regulated investment company may limit its ability to make certain investments including, without limitation, investments in certain commodity-linked derivatives. The IRS has issued a revenue ruling which holds that income derived from certain commodity-linked swaps is not qualifying income under Subchapter M of the Code. The IRS has issued private letter rulings to other taxpayers in which the IRS concluded that income from certain commodity-linked notes is qualifying income and that income derived from a wholly-owned subsidiary will also constitute qualifying income. There can be no assurance that the IRS will not change its position that income derived from commodity-linked notes and wholly-owned subsidiaries is qualifying income. The IRS recently issued proposed regulations that, if finalized, would generally treat the Fund’s income inclusion with respect to its Subsidiary as qualifying income only if there is a distribution out of the earnings and profits of the Subsidiary that are attributable to such income inclusion. The proposed regulations, if adopted, would apply to taxable years beginning on or after 90 days after the regulations are published as final. The IRS also recently issued a revenue procedure, which states that the IRS will not in the future issue private letter rulings that would require a determination of whether an asset (such as a commodity index-linked note) is a “security” under the 1940 Act. The tax treatment of commodity-linked notes, other commodity-linked derivatives and the Fund’s investments in the Subsidiary may be adversely affected by future legislation, court decisions, Treasury regulations and/or guidance issued by the IRS that could affect whether income from such investments is qualifying income under Subchapter M of the Code, or otherwise alter the character, timing and/or amount of the Fund’s taxable income or any gains and distributions made by the Fund. The Fund’s investment in the Subsidiary and its use of commodity-linked notes involve specific risks. See “Subsidiary Risk” for further information regarding the Subsidiary, including the risks associated with investing in the Subsidiary. See “Commodity Risk” and “Derivatives Risk” for further information regarding commodity-linked notes, including the risks associated with these instruments.

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 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. 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.

Short Selling Risk. The Fund’s strategy may involve more risk than other funds that do not engage in short selling. The Fund’s use of short sales in combination with long positions in Fund’s portfolio in an attempt to improve performance or to reduce overall portfolio risk may not be successful and may result in greater losses or lower positive returns than if the Fund held only long positions. It is possible that the Fund’s long positions will decline in value at the same time that the value of its short positions increase, thereby increasing potential losses to that Fund.

Non-Diversified Fund Risk. Since the Fund is non-diversified, it may invest a greater percentage of its assets in a particular issuer or group of issuers than a diversified fund would. This increased investment in fewer issuers may result in the Fund’s shares being more sensitive to economic results of those issuing the securities.

Investment Company Risk. The Fund may invest in shares of other investment companies. Shareholders bear both their proportionate share of the Fund’s expenses and similar expenses of the underlying investment company when the Fund invests in shares of another investment company.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

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 seeks to achieve its objective by investing in a diversified portfolio of commodity-linked derivatives. The Fund will also invest in fixed income securities.

Commodity Investments
The Fund invests in commodity-linked derivative instruments, such as commodity-linked notes, swap agreements, commodity options, futures and options on futures that provide exposure to the investment returns of the commodities markets without investing directly in physical commodities. Commodities are assets that have tangible properties, such as oil, metals, and agricultural products. Derivatives are instruments that have a value based on another instrument, exchange rate or index and will generally be used as substitutes for commodities.

The Fund will gain exposure to commodity markets by investing up to 25% of its total assets in the Commodities Strategy Fund CS Ltd., a wholly owned subsidiary of the Fund organized under the laws of the Cayman Islands (the Subsidiary). The Subsidiary is also advised by J.P. Morgan Investment Management Inc. (JPMIM or Adviser) and has the same investment objective as the Fund. The Subsidiary (unlike the Fund) may invest without limitation in commodity futures contracts, commodity-linked swap agreements and other commodity-linked derivative instruments, including derivative instruments linked to the value of a particular commodity, commodity index or commodity futures contract, or a subset of commodities or commodity futures contracts. However, the Subsidiary is otherwise subject to the same fundamental, non-fundamental and certain other investment restrictions as the Fund.

The Fund intends to provide long exposure to the commodities markets. In addition, the Subsidiary may use short positions in commodities to reduce exposure to the commodities market. Although the long and short positions held by the Subsidiary will vary in size as market opportunities change, the Fund intends to maintain a net exposure to the commodities market within a range of 70% to 130% of the value of the Fund’s net assets. The Subsidiary may use derivatives to obtain long or short exposure in an attempt to increase the Subsidiary’s income or gain, to hedge various investments and for risk management. In rising markets, the Fund expects that the value of the long positions will appreciate more rapidly than the short positions, and in declining markets, that the value of the short positions will appreciate more rapidly than the long positions.

The Fund’s or the Subsidiary’s investments in commodity-linked derivative instruments may deviate from the returns of any particular commodity index. The Fund or the Subsidiary may also overweight or underweight its exposure to a subset of commodities, such that the Fund has greater or lesser exposure to a subset of commodities than is represented by a particular commodity index.

Fixed Income Investments
Assets not invested in commodity-linked derivatives, currency-linked derivatives or the Subsidiary will be invested in high quality, short term fixed income securities. The fixed income portion of the Fund is intended to provide liquidity and preserve capital. The Fund’s fixed income securities may include: obligations of the U.S. Treasury, including Treasury bills, bonds and notes and other obligations issued or guaranteed by the U.S. Treasury; Treasury Inflation Protected Securities (TIPS); securities issued or guaranteed by the U.S. government, its agencies or instrumentalities; high quality commercial paper and other short-term debt securities, including floating and variable rate demand notes, of U.S. and foreign corporations; debt securities issued or guaranteed by U.S., foreign, and supranational banks, including certificates of deposit, time deposits and other short-term securities; repurchase agreements fully collateralized by U.S. Treasury and U.S. government securities; and corporate debt obligations. The Fund generally will only buy securities that have remaining maturities of 397 days or less. The dollar-weighted average maturity of the Fund’s fixed income investments will generally be 90 days or less. The Fund may also invest in affiliated money market funds.

The Subsidiary will also invest in fixed income securities, either as investments or to serve as margin or collateral for its derivative positions.

Investment Process:

JPMIM uses a global quarterly and weekly investment process that applies fundamental, quantitative, and technical analysis to develop investment themes in each commodity market. The process includes a global team of investors across markets and sectors. JPMIM utilizes the output of the global investment process to position the Fund’s exposure to the broader commodities market. JPMIM uses sector investment specialists to perform fundamental and quantitative analysis on each commodity and utilizes their inputs in its decision to over/underweight individual commodity holdings relative to the Fund’s benchmark. JPMIM seeks to enhance returns by using its analysis of each commodity to decide the time to delivery of each holding.

Fixed Income Investments Process
JPMIM seeks to develop an appropriate fixed income portfolio and buys and sells securities by considering the differences in yields among securities of different maturities, market sectors and issuers.

The frequency with which the Fund buys and sells securities will vary from year to year, depending on market conditions.

The Fund is non-diversified.

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 instruments 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

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. Securities in the Fund’s portfolio may underperform securities in comparison to general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Commodity Risk. Because the Fund will have a significant portion of its assets concentrated in commodity-linked securities, developments affecting commodities will have a disproportionate impact on the Fund. The Fund’s investment in commodity-linked derivative instruments may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked derivative instruments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. 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.

CFTC Regulation Risk. The Fund is subject to regulation by the Commodity Futures Trading Commission (CFTC) as a “commodity pool” and the Adviser is subject to regulation as a “commodity pool operator” with respect to the Fund. As a result, the Fund is subject to various CFTC requirements, including certain registration, disclosure and operational requirements. Compliance with these requirements may increase Fund expenses.

Derivatives Risk. Derivatives, including commodity-linked notes, swap agreements, commodity options, futures and options on futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations) and to the credit risk of the derivative counterparty. 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.

Swap Agreement Risk. In addition to the risks associated with derivatives in general, the Fund will also be subject to risks related to swap agreements. The Subsidiary may use swaps to establish both long and short positions in order to gain the desired exposure. The Fund’s losses are potentially unlimited in short sale positions. Short sales are speculative transactions and involve special risks, including greater reliance on the Adviser’s ability to accurately anticipate the future value of an instrument. 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.

Counterparty Risk. Commodity-linked derivatives, repurchase agreements, swap agreements and other forms of financial instruments that involve counterparties subject the Fund to the risk that the counterparty could default on its obligations under the agreement, either through the counterparty’s bankruptcy or failure to perform its obligations. In the event of default, the Fund could experience lengthy delays in recovering some or all of its assets or no recovery at all.

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 impacted by that currency loses value because that currency is worth less in U.S. dollars. Currency exchange rates may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates. 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. Although the Fund may attempt to hedge its currency exposure into the U.S. dollar, it may not be successful in reducing the effects of currency fluctuations. The Fund may also hedge from one foreign currency to another. 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.

Interest Rate Risk. The Fund’s investments in bonds and other debt securities will change in value based on changes in interest rates. If rates increase, the value of the Fund’s investments generally declines. On the other hand, if rates fall, the value of the investments generally increases. Your investment will decline in value if the value of the investments decreases. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Usually, the changes in the value of fixed income securities will not affect cash income generated, but may affect the value of your investment. Given the historically low interest rate environment, risks associated with rising rates are heightened.

Credit Risk. There is a risk that issuers and/or counterparties will not make payments on securities, repurchase agreements or other investments held by the Fund. Such defaults could result in losses to the Fund. In addition, the credit quality of securities held by the Fund may be lowered if an issuer’s or a counterparty’s financial condition changes. Lower credit quality may lead to greater volatility in the price of a security and in shares of the Fund. Lower credit quality also may affect liquidity and make it difficult for the Fund to sell the security. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Inflation-Linked Security Risk. Inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of an inflation-linked security tends to decrease when real interest rates increase and can increase when real interest rates decrease. Interest payments on inflation-linked securities are unpredictable and will fluctuate as the principal and interest are adjusted for inflation. Any increase in the principal amount of an inflation-linked debt security will be considered taxable ordinary income, even though the Fund will not receive the principal until maturity. There can also be no assurance that the inflation index used will accurately measure the real rate of inflation in the prices of goods and services. The Fund’s investments in inflation-linked securities may lose value in the event that the actual rate of inflation is different than the rate of the inflation index. In addition, inflation-linked securities are subject to the risk that the Consumer Price Index for all Urban Consumers (CPI-U) or other relevant pricing index may be discontinued, fundamentally altered in a manner materially adverse to the interests of an investor in the securities, altered by legislation or Executive Order in a materially adverse manner to the interests of an investor in the securities or substituted with an alternative index.

Government Securities Risk. The Fund invests in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac)).

U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. 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 will provide financial support. Therefore, U.S. government related organizations may not have the funds to meet their payment obligations in the future.

Tax Risk. The Fund gains exposure to the commodities markets through investments in commodity-linked derivative instruments, including commodity index-linked notes, swap agreements, commodity options, futures, and options on futures. The Fund intends to gain exposure indirectly to commodity markets by investing in its Subsidiary, which invests primarily in commodity-linked derivative instruments. In order for the Fund to qualify as a regulated investment company under Subchapter M of Internal Revenue Code, as amended (the Code), the Fund must derive at least 90 percent of its gross income each taxable year from certain qualifying sources of income. The Fund’s intention to qualify as a regulated investment company may limit its ability to make certain investments including, without limitation, investments in certain commodity-linked derivatives. The IRS has issued a revenue ruling which holds that income derived from certain commodity-linked swaps is not qualifying income under Subchapter M of the Code. The IRS has issued private letter rulings to other taxpayers in which the IRS concluded that income from certain commodity-linked notes is qualifying income and that income derived from a wholly-owned subsidiary will also constitute qualifying income. There can be no assurance that the IRS will not change its position that income derived from commodity-linked notes and wholly-owned subsidiaries is qualifying income. The IRS recently issued proposed regulations that, if finalized, would generally treat the Fund’s income inclusion with respect to its Subsidiary as qualifying income only if there is a distribution out of the earnings and profits of the Subsidiary that are attributable to such income inclusion. The proposed regulations, if adopted, would apply to taxable years beginning on or after 90 days after the regulations are published as final. The IRS also recently issued a revenue procedure, which states that the IRS will not in the future issue private letter rulings that would require a determination of whether an asset (such as a commodity index-linked note) is a “security” under the 1940 Act. The tax treatment of commodity-linked notes, other commodity-linked derivatives and the Fund’s investments in the Subsidiary may be adversely affected by future legislation, court decisions, Treasury regulations and/or guidance issued by the IRS that could affect whether income from such investments is qualifying income under Subchapter M of the Code, or otherwise alter the character, timing and/or amount of the Fund’s taxable income or any gains and distributions made by the Fund. The Fund’s investment in the Subsidiary and its use of commodity-linked notes involve specific risks. See “Subsidiary Risk” for further information regarding the Subsidiary, including the risks associated with investing in the Subsidiary. See “Commodity Risk” and “Derivatives Risk” for further information regarding commodity-linked notes, including the risks associated with these instruments.

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 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. 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.

Short Selling Risk. The Fund’s strategy may involve more risk than other funds that do not engage in short selling. The Fund’s use of short sales in combination with long positions in Fund’s portfolio in an attempt to improve performance or to reduce overall portfolio risk may not be successful and may result in greater losses or lower positive returns than if the Fund held only long positions. It is possible that the Fund’s long positions will decline in value at the same time that the value of its short positions increase, thereby increasing potential losses to that Fund.

Non-Diversified Fund Risk. Since the Fund is non-diversified, it may invest a greater percentage of its assets in a particular issuer or group of issuers than a diversified fund would. This increased investment in fewer issuers may result in the Fund’s shares being more sensitive to economic results of those issuing the securities.

Investment Company Risk. The Fund may invest in shares of other investment companies. Shareholders bear both their proportionate share of the Fund’s expenses and similar expenses of the underlying investment company when the Fund invests in shares of another investment company.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

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.

R6 Shares | JPMorgan Commodities Strategy Fund

JPMorgan Commodities Strategy Fund

Class/Ticker: R6/CSFVX

What is the goal of the Fund?

The Fund seeks total return.

Fees and Expenses of the Fund

The following table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. “Acquired Fund Fees and Expenses” are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies, including affiliated money market funds, other mutual funds, exchange-traded funds and business development companies. The impact of Acquired Fund Fees and Expenses is included in the total returns of the Fund. Acquired Fund Fees and Expenses are not direct costs of the Fund, are not used to calculate the Fund’s net asset value per share and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus.

ANNUAL FUND OPERATING EXPENSES
(Expenses that you pay each year as a percentage of the value
of your investment)

Annual Fund Operating Expenses	R6 Shares JPMorgan Commodities Strategy Fund Class R6	[1]
Management Fees	0.85%
Distribution (Rule 12b-1) Fees	none
Other Expenses	1.00%
Shareholder Service Fees	none
Remainder of Other Expenses	1.00%	[2]
Acquired Fund Fees and Expenses	0.03%
Total Annual Fund Operating Expenses	1.88%
Fee Waivers and Expense Reimbursements	(1.03%)	[3],[4]
Total Annual Fund Operating Expenses After Fee Waivers and Expense Reimbursements	0.85%	[3],[4]

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. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 2/28/18 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

WHETHER YOU SELL YOUR SHARES, YOUR COST
WOULD BE:

Expense Example	1 Year	3 Years	5 Years	10 Years
R6 Shares | JPMorgan Commodities Strategy Fund | CLASS R6 SHARES | USD ($)	87	491	920	2,117

WHETHER YOU SELL YOUR SHARES, YOUR COST
WOULD BE:

Expense Example, No Redemption	1 Year	3 Years	5 Years	10 Years
R6 Shares | JPMorgan Commodities Strategy Fund | CLASS R6 SHARES | USD ($)	87	491	920	2,117

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. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 0% of the average value of its portfolio.

What are the Fund’s main investment strategies?

The Fund seeks to achieve its objective by investing in a diversified portfolio of commodity-linked derivatives. The Fund will also invest in fixed income securities.

Commodity Investments
The Fund invests in commodity-linked derivative instruments, such as commodity-linked notes, swap agreements, commodity options, futures and options on futures that provide exposure to the investment returns of the commodities markets without investing directly in physical commodities. Commodities are assets that have tangible properties, such as oil, metals, and agricultural products. Derivatives are instruments that have a value based on another instrument, exchange rate or index and will generally be used as substitutes for commodities.

The Fund will gain exposure to commodity markets by investing up to 25% of its total assets in the Commodities Strategy Fund CS Ltd., a wholly owned subsidiary of the Fund organized under the laws of the Cayman Islands (the Subsidiary). The Subsidiary is also advised by J.P. Morgan Investment Management Inc. (JPMIM or Adviser) and has the same investment objective as the Fund. The Subsidiary (unlike the Fund) may invest without limitation in commodity futures contracts, commodity-linked swap agreements and other commodity-linked derivative instruments, including derivative instruments linked to the value of a particular commodity, commodity index or commodity futures contract, or a subset of commodities or commodity futures contracts. However, the Subsidiary is otherwise subject to the same fundamental, non-fundamental and certain other investment restrictions as the Fund.

The Fund intends to provide long exposure to the commodities markets. In addition, the Subsidiary may use short positions in commodities to reduce exposure to the commodities market. Although the long and short positions held by the Subsidiary will vary in size as market opportunities change, the Fund intends to maintain a net exposure to the commodities market within a range of 70% to 130% of the value of the Fund’s net assets. The Subsidiary may use derivatives to obtain long or short exposure in an attempt to increase the Subsidiary’s income or gain, to hedge various investments and for risk management. In rising markets, the Fund expects that the value of the long positions will appreciate more rapidly than the short positions, and in declining markets, that the value of the short positions will appreciate more rapidly than the long positions.

The Fund’s or the Subsidiary’s investments in commodity-linked derivative instruments may deviate from the returns of any particular commodity index. The Fund or the Subsidiary may also overweight or underweight its exposure to a subset of commodities, such that the Fund has greater or lesser exposure to a subset of commodities than is represented by a particular commodity index.

Fixed Income Investments
Assets not invested in commodity-linked derivatives, currency-linked derivatives or the Subsidiary will be invested in high quality, short-term fixed income securities. The fixed income portion of the Fund is intended to provide liquidity and preserve capital. The Fund’s fixed income securities may include: obligations of the U.S. Treasury, including Treasury bills, bonds and notes and other obligations issued or guaranteed by the U.S. Treasury; Treasury Inflation Protected Securities (TIPS); securities issued or guaranteed by the U.S. government, its agencies or instrumentalities; high quality commercial paper and other short-term debt securities, including floating and variable rate demand notes, of U.S. and foreign corporations; debt securities issued or guaranteed by U.S., foreign, and supranational banks, including certificates of deposit, time deposits and other short-term securities; repurchase agreements fully collateralized by U.S. Treasury and U.S. government securities; and corporate debt obligations. The Fund generally will only buy securities that have remaining maturities of 397 days or less. The dollar-weighted average maturity of the Fund’s fixed income investments will generally be 90 days or less. The Fund may also invest in affiliated money market funds.

The Subsidiary will also invest in fixed income securities, either as investments or to serve as margin or collateral for its derivative positions.

Investment Process:

JPMIM uses a global quarterly and weekly investment process that applies fundamental, quantitative, and technical analysis to develop investment themes in each commodity market. The process includes a global team of investors across markets and sectors. JPMIM utilizes the output of the global investment process to position the Fund’s exposure to the broader commodities market. JPMIM uses sector investment specialists to perform fundamental and quantitative analysis on each commodity and utilizes their inputs in its decision to over/underweight individual commodity holdings relative to the Fund’s benchmark. JPMIM seeks to enhance returns by using its analysis of each commodity to decide the time to delivery of each holding.

Fixed Income Investments Process
JPMIM seeks to develop an appropriate fixed income portfolio and buys and sells securities by considering the differences in yields among securities of different maturities, market sectors and issuers.

The frequency with which the Fund buys and sells securities will vary from year to year, depending on market conditions.

The Fund is non-diversified.

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 instruments 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

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. Securities in the Fund’s portfolio may underperform securities in comparison to general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Commodity Risk. Because the Fund will have a significant portion of its assets concentrated in commodity-linked securities, developments affecting commodities will have a disproportionate impact on the Fund. The Fund’s investment in commodity-linked derivative instruments may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked derivative instruments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. 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.

CFTC Regulation Risk. The Fund is subject to regulation by the Commodity Futures Trading Commission (CFTC) as a “commodity pool” and the Adviser is subject to regulation as a “commodity pool operator” with respect to the Fund. As a result, the Fund is subject to various CFTC requirements, including certain registration, disclosure and operational requirements. Compliance with these requirements may increase Fund expenses.

Derivatives Risk. Derivatives, including commodity-linked notes, swap agreements, commodity options, futures and options on futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations) and to the credit risk of the derivative counterparty. 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.

Swap Agreement Risk. In addition to the risks associated with derivatives in general, the Fund will also be subject to risks related to swap agreements. The Subsidiary may use swaps to establish both long and short positions in order to gain the desired exposure. The Fund’s losses are potentially unlimited in short sale positions. Short sales are speculative transactions and involve special risks, including greater reliance on the Adviser’s ability to accurately anticipate the future value of an instrument. 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.

Counterparty Risk. Commodity-linked derivatives, repurchase agreements, swap agreements and other forms of financial instruments that involve counterparties subject the Fund to the risk that the counterparty could default on its obligations under the agreement, either through the counterparty’s bankruptcy or failure to perform its obligations. In the event of default, the Fund could experience lengthy delays in recovering some or all of its assets or no recovery at all.

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 impacted by that currency loses value because that currency is worth less in U.S. dollars. Currency exchange rates may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates. 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. Although the Fund may attempt to hedge its currency exposure into the U.S. dollar, it may not be successful in reducing the effects of currency fluctuations. The Fund may also hedge from one foreign currency to another. 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.

Interest Rate Risk. The Fund’s investments in bonds and other debt securities will change in value based on changes in interest rates. If rates increase, the value of the Fund’s investments generally declines. On the other hand, if rates fall, the value of the investments generally increases. Your investment will decline in value if the value of the investments decreases. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Usually, the changes in the value of fixed income securities will not affect cash income generated, but may affect the value of your investment. Given the historically low interest rate environment, risks associated with rising rates are heightened.

Credit Risk. There is a risk that issuers and/or counterparties will not make payments on securities, repurchase agreements or other investments held by the Fund. Such defaults could result in losses to the Fund. In addition, the credit quality of securities held by the Fund may be lowered if an issuer’s or a counterparty’s financial condition changes. Lower credit quality may lead to greater volatility in the price of a security and in shares of the Fund. Lower credit quality also may affect liquidity and make it difficult for the Fund to sell the security. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Inflation-Linked Security Risk. Inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of an inflation-linked security tends to decrease when real interest rates increase and can increase when real interest rates decrease. Interest payments on inflation-linked securities are unpredictable and will fluctuate as the principal and interest are adjusted for inflation. Any increase in the principal amount of an inflation-linked debt security will be considered taxable ordinary income, even though the Fund will not receive the principal until maturity. There can also be no assurance that the inflation index used will accurately measure the real rate of inflation in the prices of goods and services. The Fund’s investments in inflation-linked securities may lose value in the event that the actual rate of inflation is different than the rate of the inflation index. In addition, inflation-linked securities are subject to the risk that the Consumer Price Index for all Urban Consumers (CPI-U) or other relevant pricing index may be discontinued, fundamentally altered in a manner materially adverse to the interests of an investor in the securities, altered by legislation or Executive Order in a materially adverse manner to the interests of an investor in the securities or substituted with an alternative index.

Government Securities Risk. The Fund invests in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. 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 will provide financial support. Therefore, U.S. government related organizations may not have the funds to meet their payment obligations in the future.

Tax Risk. The Fund gains exposure to the commodities markets through investments in commodity-linked derivative instruments, including commodity index-linked notes, swap agreements, commodity options, futures, and options on futures. The Fund intends to gain exposure indirectly to commodity markets by investing in its Subsidiary, which invests primarily in commodity-linked derivative instruments. In order for the Fund to qualify as a regulated investment company under Subchapter M of Internal Revenue Code, as amended (the Code), the Fund must derive at least 90 percent of its gross income each taxable year from certain qualifying sources of income. The Fund’s intention to qualify as a regulated investment company may limit its ability to make certain investments including, without limitation, investments in certain commodity-linked derivatives. The IRS has issued a revenue ruling which holds that income derived from certain commodity-linked swaps is not qualifying income under Subchapter M of the Code. The IRS has issued private letter rulings to other taxpayers in which the IRS concluded that income from certain commodity-linked notes is qualifying income and that income derived from a wholly-owned subsidiary will also constitute qualifying income. There can be no assurance that the IRS will not change its position that income derived from commodity-linked notes and wholly-owned subsidiaries is qualifying income. The IRS recently issued proposed regulations that, if finalized, would generally treat the Fund’s income inclusion with respect to its Subsidiary as qualifying income only if there is a distribution out of the earnings and profits of the Subsidiary that are attributable to such income inclusion. The proposed regulations, if adopted, would apply to taxable years beginning on or after 90 days after the regulations are published as final. The IRS also recently issued a revenue procedure, which states that the IRS will not in the future issue private letter rulings that would require a determination of whether an asset (such as a commodity index-linked note) is a “security” under the 1940 Act. The tax treatment of commodity-linked notes, other commodity-linked derivatives and the Fund’s investments in the Subsidiary may be adversely affected by future legislation, court decisions, Treasury regulations and/or guidance issued by the IRS that could affect whether income from such investments is qualifying income under Subchapter M of the Code, or otherwise alter the character, timing and/or amount of the Fund’s taxable income or any gains and distributions made by the Fund. The Fund’s investment in the Subsidiary and its use of commodity-linked notes involve specific risks. See “Subsidiary Risk” for further information regarding the Subsidiary, including the risks associated with investing in the Subsidiary. See “Commodity Risk” and “Derivatives Risk” for further information regarding commodity-linked notes, including the risks associated with these instruments.

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 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. 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.

Short Selling Risk. The Fund’s strategy may involve more risk than other funds that do not engage in short selling. The Fund’s use of short sales in combination with long positions in Fund’s portfolio in an attempt to improve performance or to reduce overall portfolio risk may not be successful and may result in greater losses or lower positive returns than if the Fund held only long positions. It is possible that the Fund’s long positions will decline in value at the same time that the value of its short positions increase, thereby increasing potential losses to that Fund.

Non-Diversified Fund Risk. Since the Fund is non-diversified, it may invest a greater percentage of its assets in a particular issuer or group of issuers than a diversified fund would. This increased investment in fewer issuers may result in the Fund’s shares being more sensitive to economic results of those issuing the securities.

Investment Company Risk. The Fund may invest in shares of other investment companies. Shareholders bear both their proportionate share of the Fund’s expenses and similar expenses of the underlying investment company when the Fund invests in shares of another investment company.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

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.

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its objective by investing in a diversified portfolio of commodity-linked derivatives. The Fund will also invest in fixed income securities.

Commodity Investments
The Fund invests in commodity-linked derivative instruments, such as commodity-linked notes, swap agreements, commodity options, futures and options on futures that provide exposure to the investment returns of the commodities markets without investing directly in physical commodities. Commodities are assets that have tangible properties, such as oil, metals, and agricultural products. Derivatives are instruments that have a value based on another instrument, exchange rate or index and will generally be used as substitutes for commodities.

The Fund will gain exposure to commodity markets by investing up to 25% of its total assets in the Commodities Strategy Fund CS Ltd., a wholly owned subsidiary of the Fund organized under the laws of the Cayman Islands (the Subsidiary). The Subsidiary is also advised by J.P. Morgan Investment Management Inc. (JPMIM or Adviser) and has the same investment objective as the Fund. The Subsidiary (unlike the Fund) may invest without limitation in commodity futures contracts, commodity-linked swap agreements and other commodity-linked derivative instruments, including derivative instruments linked to the value of a particular commodity, commodity index or commodity futures contract, or a subset of commodities or commodity futures contracts. However, the Subsidiary is otherwise subject to the same fundamental, non-fundamental and certain other investment restrictions as the Fund.

The Fund intends to provide long exposure to the commodities markets. In addition, the Subsidiary may use short positions in commodities to reduce exposure to the commodities market. Although the long and short positions held by the Subsidiary will vary in size as market opportunities change, the Fund intends to maintain a net exposure to the commodities market within a range of 70% to 130% of the value of the Fund’s net assets. The Subsidiary may use derivatives to obtain long or short exposure in an attempt to increase the Subsidiary’s income or gain, to hedge various investments and for risk management. In rising markets, the Fund expects that the value of the long positions will appreciate more rapidly than the short positions, and in declining markets, that the value of the short positions will appreciate more rapidly than the long positions.

The Fund’s or the Subsidiary’s investments in commodity-linked derivative instruments may deviate from the returns of any particular commodity index. The Fund or the Subsidiary may also overweight or underweight its exposure to a subset of commodities, such that the Fund has greater or lesser exposure to a subset of commodities than is represented by a particular commodity index.

Fixed Income Investments
Assets not invested in commodity-linked derivatives, currency-linked derivatives or the Subsidiary will be invested in high quality, short-term fixed income securities. The fixed income portion of the Fund is intended to provide liquidity and preserve capital. The Fund’s fixed income securities may include: obligations of the U.S. Treasury, including Treasury bills, bonds and notes and other obligations issued or guaranteed by the U.S. Treasury; Treasury Inflation Protected Securities (TIPS); securities issued or guaranteed by the U.S. government, its agencies or instrumentalities; high quality commercial paper and other short-term debt securities, including floating and variable rate demand notes, of U.S. and foreign corporations; debt securities issued or guaranteed by U.S., foreign, and supranational banks, including certificates of deposit, time deposits and other short-term securities; repurchase agreements fully collateralized by U.S. Treasury and U.S. government securities; and corporate debt obligations. The Fund generally will only buy securities that have remaining maturities of 397 days or less. The dollar-weighted average maturity of the Fund’s fixed income investments will generally be 90 days or less. The Fund may also invest in affiliated money market funds.

The Subsidiary will also invest in fixed income securities, either as investments or to serve as margin or collateral for its derivative positions.

Investment Process:

JPMIM uses a global quarterly and weekly investment process that applies fundamental, quantitative, and technical analysis to develop investment themes in each commodity market. The process includes a global team of investors across markets and sectors. JPMIM utilizes the output of the global investment process to position the Fund’s exposure to the broader commodities market. JPMIM uses sector investment specialists to perform fundamental and quantitative analysis on each commodity and utilizes their inputs in its decision to over/underweight individual commodity holdings relative to the Fund’s benchmark. JPMIM seeks to enhance returns by using its analysis of each commodity to decide the time to delivery of each holding.

Fixed Income Investments Process
JPMIM seeks to develop an appropriate fixed income portfolio and buys and sells securities by considering the differences in yields among securities of different maturities, market sectors and issuers.

The frequency with which the Fund buys and sells securities will vary from year to year, depending on market conditions.

The Fund is non-diversified.

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 instruments 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

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. Securities in the Fund’s portfolio may underperform securities in comparison to general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Commodity Risk. Because the Fund will have a significant portion of its assets concentrated in commodity-linked securities, developments affecting commodities will have a disproportionate impact on the Fund. The Fund’s investment in commodity-linked derivative instruments may subject the Fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked derivative instruments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. 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.

CFTC Regulation Risk. The Fund is subject to regulation by the Commodity Futures Trading Commission (CFTC) as a “commodity pool” and the Adviser is subject to regulation as a “commodity pool operator” with respect to the Fund. As a result, the Fund is subject to various CFTC requirements, including certain registration, disclosure and operational requirements. Compliance with these requirements may increase Fund expenses.

Derivatives Risk. Derivatives, including commodity-linked notes, swap agreements, commodity options, futures and options on futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations) and to the credit risk of the derivative counterparty. 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.

Swap Agreement Risk. In addition to the risks associated with derivatives in general, the Fund will also be subject to risks related to swap agreements. The Subsidiary may use swaps to establish both long and short positions in order to gain the desired exposure. The Fund’s losses are potentially unlimited in short sale positions. Short sales are speculative transactions and involve special risks, including greater reliance on the Adviser’s ability to accurately anticipate the future value of an instrument. 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.

Counterparty Risk. Commodity-linked derivatives, repurchase agreements, swap agreements and other forms of financial instruments that involve counterparties subject the Fund to the risk that the counterparty could default on its obligations under the agreement, either through the counterparty’s bankruptcy or failure to perform its obligations. In the event of default, the Fund could experience lengthy delays in recovering some or all of its assets or no recovery at all.

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 impacted by that currency loses value because that currency is worth less in U.S. dollars. Currency exchange rates may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates. 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. Although the Fund may attempt to hedge its currency exposure into the U.S. dollar, it may not be successful in reducing the effects of currency fluctuations. The Fund may also hedge from one foreign currency to another. 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.

Interest Rate Risk. The Fund’s investments in bonds and other debt securities will change in value based on changes in interest rates. If rates increase, the value of the Fund’s investments generally declines. On the other hand, if rates fall, the value of the investments generally increases. Your investment will decline in value if the value of the investments decreases. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. Usually, the changes in the value of fixed income securities will not affect cash income generated, but may affect the value of your investment. Given the historically low interest rate environment, risks associated with rising rates are heightened.

Credit Risk. There is a risk that issuers and/or counterparties will not make payments on securities, repurchase agreements or other investments held by the Fund. Such defaults could result in losses to the Fund. In addition, the credit quality of securities held by the Fund may be lowered if an issuer’s or a counterparty’s financial condition changes. Lower credit quality may lead to greater volatility in the price of a security and in shares of the Fund. Lower credit quality also may affect liquidity and make it difficult for the Fund to sell the security. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

Inflation-Linked Security Risk. Inflation-linked debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the price of an inflation-linked security tends to decrease when real interest rates increase and can increase when real interest rates decrease. Interest payments on inflation-linked securities are unpredictable and will fluctuate as the principal and interest are adjusted for inflation. Any increase in the principal amount of an inflation-linked debt security will be considered taxable ordinary income, even though the Fund will not receive the principal until maturity. There can also be no assurance that the inflation index used will accurately measure the real rate of inflation in the prices of goods and services. The Fund’s investments in inflation-linked securities may lose value in the event that the actual rate of inflation is different than the rate of the inflation index. In addition, inflation-linked securities are subject to the risk that the Consumer Price Index for all Urban Consumers (CPI-U) or other relevant pricing index may be discontinued, fundamentally altered in a manner materially adverse to the interests of an investor in the securities, altered by legislation or Executive Order in a materially adverse manner to the interests of an investor in the securities or substituted with an alternative index.

Government Securities Risk. The Fund invests in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), or the Federal Home Loan Mortgage Corporation (Freddie Mac)). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Fund. 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 will provide financial support. Therefore, U.S. government related organizations may not have the funds to meet their payment obligations in the future.

Tax Risk. The Fund gains exposure to the commodities markets through investments in commodity-linked derivative instruments, including commodity index-linked notes, swap agreements, commodity options, futures, and options on futures. The Fund intends to gain exposure indirectly to commodity markets by investing in its Subsidiary, which invests primarily in commodity-linked derivative instruments. In order for the Fund to qualify as a regulated investment company under Subchapter M of Internal Revenue Code, as amended (the Code), the Fund must derive at least 90 percent of its gross income each taxable year from certain qualifying sources of income. The Fund’s intention to qualify as a regulated investment company may limit its ability to make certain investments including, without limitation, investments in certain commodity-linked derivatives. The IRS has issued a revenue ruling which holds that income derived from certain commodity-linked swaps is not qualifying income under Subchapter M of the Code. The IRS has issued private letter rulings to other taxpayers in which the IRS concluded that income from certain commodity-linked notes is qualifying income and that income derived from a wholly-owned subsidiary will also constitute qualifying income. There can be no assurance that the IRS will not change its position that income derived from commodity-linked notes and wholly-owned subsidiaries is qualifying income. The IRS recently issued proposed regulations that, if finalized, would generally treat the Fund’s income inclusion with respect to its Subsidiary as qualifying income only if there is a distribution out of the earnings and profits of the Subsidiary that are attributable to such income inclusion. The proposed regulations, if adopted, would apply to taxable years beginning on or after 90 days after the regulations are published as final. The IRS also recently issued a revenue procedure, which states that the IRS will not in the future issue private letter rulings that would require a determination of whether an asset (such as a commodity index-linked note) is a “security” under the 1940 Act. The tax treatment of commodity-linked notes, other commodity-linked derivatives and the Fund’s investments in the Subsidiary may be adversely affected by future legislation, court decisions, Treasury regulations and/or guidance issued by the IRS that could affect whether income from such investments is qualifying income under Subchapter M of the Code, or otherwise alter the character, timing and/or amount of the Fund’s taxable income or any gains and distributions made by the Fund. The Fund’s investment in the Subsidiary and its use of commodity-linked notes involve specific risks. See “Subsidiary Risk” for further information regarding the Subsidiary, including the risks associated with investing in the Subsidiary. See “Commodity Risk” and “Derivatives Risk” for further information regarding commodity-linked notes, including the risks associated with these instruments.

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 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. 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.

Short Selling Risk. The Fund’s strategy may involve more risk than other funds that do not engage in short selling. The Fund’s use of short sales in combination with long positions in Fund’s portfolio in an attempt to improve performance or to reduce overall portfolio risk may not be successful and may result in greater losses or lower positive returns than if the Fund held only long positions. It is possible that the Fund’s long positions will decline in value at the same time that the value of its short positions increase, thereby increasing potential losses to that Fund.

Non-Diversified Fund Risk. Since the Fund is non-diversified, it may invest a greater percentage of its assets in a particular issuer or group of issuers than a diversified fund would. This increased investment in fewer issuers may result in the Fund’s shares being more sensitive to economic results of those issuing the securities.

Investment Company Risk. The Fund may invest in shares of other investment companies. Shareholders bear both their proportionate share of the Fund’s expenses and similar expenses of the underlying investment company when the Fund invests in shares of another investment company.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

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.

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. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 2/28/18 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

IF YOU SELL YOUR SHARES, YOUR COST WOULD BE:

Expense Example - A, C, Select Shares - JPMorgan Research Market Neutral Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	846	1,553	2,279	4,185
CLASS C SHARES	488	1,225	2,077	4,275
SELECT CLASS SHARES	313	1,005	1,720	3,615

IF YOU DO NOT SELL YOUR SHARES, YOUR COST
WOULD BE:

Expense Example, No Redemption - A, C, Select Shares - JPMorgan Research Market Neutral Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	846	1,553	2,279	4,185
CLASS C SHARES	388	1,225	2,077	4,275
SELECT CLASS SHARES	313	1,005	1,720	3,615

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. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate (including short sales) was 298% of the average value of its portfolio.

What are the Fund’s main investment strategies?

The Fund takes long and short positions in different securities, selecting from a universe of mid- to large-capitalization stocks with characteristics similar to those of the Russell 1000 and/or Standard & Poor’s 500 (S&P 500) Indexes, in an effort to insulate the Fund’s performance from the effects of general stock market movements. As of the last reconstitution of the Russell 1000 Index on June 24, 2016, the companies in the index included companies with market capitalizations ranging from $1.5 billion to $504.1 billion. As of the last reconstitution of the S&P 500 Index on September 30, 2016, the companies in the index included companies with market capitalizations of $1.1 billion to $609.2 billion.

In rising markets, the Fund expects that the long positions will appreciate more rapidly than the short positions, and in declining markets that the short positions will decline faster than the long positions. The Fund expects that this difference in rates of appreciation, along with any returns on cash generated by short sales, will generate a positive return; the Fund pursues returns exceeding those of 90-day U.S. Treasury Bills.

The Fund purchases securities that it believes are undervalued and sells short securities that it believes are overvalued. The long and short positions are matched on a variety of risk characteristics in order to limit exposure to macroeconomic factors.

In each sector in which the Fund invests, it balances the dollars invested in long and short positions to remain sector neutral. In attempting to neutralize market and sector risks, the Fund emphasizes stock selection as the primary means of generating returns.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. The Fund may use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: In managing the Fund the adviser employs a three-step process that combines research, valuation and stock selection.

The research findings allow the adviser to rank the companies according to what it believes to be their relative value. The greater a company’s estimated worth compared to the current market price of its stock, the more undervalued the company. The valuation rankings are produced with the help of a variety of models that quantify the research team’s findings.

The Fund buys and sells securities according to its own policies, using the research and valuation rankings as a basis. In general, the team selects securities that are identified as undervalued and considers selling them when they appear overvalued. Along with attractive valuation, the team often considers a number of other criteria:

• catalysts that could trigger a rise in a stock’s price

• impact on the overall risk of the portfolio relative to the benchmark

• temporary mispricings caused by market overreactions

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 instruments 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Strategy Risk. There is no guarantee that the use of long and short positions will succeed in limiting the Fund’s exposure to domestic stock market movements, capitalization, sector-swings or other risk factors.

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. When the value of the Fund’s securities goes down, the value of your investment in the Fund decreases in value.

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. Securities in the Fund’s portfolio may underperform securities in comparison to general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

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 the short sale and the date on which the Fund purchases the security to replace the borrowed security. In addition, a lender may request, or market conditions may dictate, that securities sold short be returned to the lender on short notice, and the Fund may have to buy the securities sold short at an unfavorable price. If this occurs, any anticipated gain to the Fund may be reduced or eliminated or the short sale may result in a loss. The Fund’s losses are potentially unlimited in a short sale transaction. 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.

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.

Derivatives Risk. Derivatives, including futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including the credit risk of the derivative counterparty. 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. Certain of the Fund’s transactions in derivatives could also affect the amount, timing and character of distributions to shareholders which may result in the Fund realizing more short-term capital gain and ordinary income subject to tax at ordinary income tax rates than it would if it did not engage in such transactions, which may adversely impact the Fund’s after-tax returns.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

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.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how performance of the Fund’s Class A Shares has varied from year to year over the past ten calendar years. The table shows the average annual total returns over the past one year, five years and ten years. The performance of Class C Shares prior to their inception is based on Class B Shares (all of which converted to Class A Shares on 6/19/15). The actual returns of the Class C Shares would have been similar to those shown because Class B Shares had similar expenses to Class C Shares. The performance of the Select Class Shares is based on the performance of Class L Shares prior to their inception. The actual returns of the Select Class Shares would have been lower than the returns shown because Select Class Shares have higher expenses than Class L Shares. The table compares that performance to the BofA Merrill Lynch 3-Month U.S. Treasury Bill Index and the Lipper Alternative Equity Market Neutral Funds Index, an average based on the total returns of all funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the fees and expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

The performance figures in the bar chart do not reflect any deduction for the front-end sales charge which is assessed on Class A Shares. If the sales charge were reflected, the performance figures would have been lower.

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. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate (including short sales) was 298% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund takes long and short positions in different securities, selecting from a universe of mid- to large-capitalization stocks with characteristics similar to those of the Russell 1000 and/or Standard & Poor’s 500 (S&P 500) Indexes, in an effort to insulate the Fund’s performance from the effects of general stock market movements. As of the last reconstitution of the Russell 1000 Index on June 24, 2016, the companies in the index included companies with market capitalizations ranging from $1.5 billion to $504.1 billion. As of the last reconstitution of the S&P 500 Index on September 30, 2016, the companies in the index included companies with market capitalizations of $1.1 billion to $609.2 billion.

In rising markets, the Fund expects that the long positions will appreciate more rapidly than the short positions, and in declining markets that the short positions will decline faster than the long positions. The Fund expects that this difference in rates of appreciation, along with any returns on cash generated by short sales, will generate a positive return; the Fund pursues returns exceeding those of 90-day U.S. Treasury Bills.

The Fund purchases securities that it believes are undervalued and sells short securities that it believes are overvalued. The long and short positions are matched on a variety of risk characteristics in order to limit exposure to macroeconomic factors.

In each sector in which the Fund invests, it balances the dollars invested in long and short positions to remain sector neutral. In attempting to neutralize market and sector risks, the Fund emphasizes stock selection as the primary means of generating returns.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. The Fund may use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: In managing the Fund the adviser employs a three-step process that combines research, valuation and stock selection.

The research findings allow the adviser to rank the companies according to what it believes to be their relative value. The greater a company’s estimated worth compared to the current market price of its stock, the more undervalued the company. The valuation rankings are produced with the help of a variety of models that quantify the research team’s findings.

The Fund buys and sells securities according to its own policies, using the research and valuation rankings as a basis. In general, the team selects securities that are identified as undervalued and considers selling them when they appear overvalued. Along with attractive valuation, the team often considers a number of other criteria:

• catalysts that could trigger a rise in a stock’s price

• impact on the overall risk of the portfolio relative to the benchmark

• temporary mispricings caused by market overreactions

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 instruments 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Strategy Risk. There is no guarantee that the use of long and short positions will succeed in limiting the Fund’s exposure to domestic stock market movements, capitalization, sector-swings or other risk factors.

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. When the value of the Fund’s securities goes down, the value of your investment in the Fund decreases in value.

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. Securities in the Fund’s portfolio may underperform securities in comparison to general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

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 the short sale and the date on which the Fund purchases the security to replace the borrowed security. In addition, a lender may request, or market conditions may dictate, that securities sold short be returned to the lender on short notice, and the Fund may have to buy the securities sold short at an unfavorable price. If this occurs, any anticipated gain to the Fund may be reduced or eliminated or the short sale may result in a loss. The Fund’s losses are potentially unlimited in a short sale transaction. 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.

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.

Derivatives Risk. Derivatives, including futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including the credit risk of the derivative counterparty. 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. Certain of the Fund’s transactions in derivatives could also affect the amount, timing and character of distributions to shareholders which may result in the Fund realizing more short-term capital gain and ordinary income subject to tax at ordinary income tax rates than it would if it did not engage in such transactions, which may adversely impact the Fund’s after-tax returns.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Performance Narrative [Text Block]

This section provides some indication of the risks of investing in the Fund. The bar chart shows how performance of the Fund’s Class A Shares has varied from year to year over the past ten calendar years. The table shows the average annual total returns over the past one year, five years and ten years. The performance of Class C Shares prior to their inception is based on Class B Shares (all of which converted to Class A Shares on 6/19/15). The actual returns of the Class C Shares would have been similar to those shown because Class B Shares had similar expenses to Class C Shares. The performance of the Select Class Shares is based on the performance of Class L Shares prior to their inception. The actual returns of the Select Class Shares would have been lower than the returns shown because Select Class Shares have higher expenses than Class L Shares. The table compares that performance to the BofA Merrill Lynch 3-Month U.S. Treasury Bill Index and the Lipper Alternative Equity Market Neutral Funds Index, an average based on the total returns of all funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the fees and expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

L Shares | JPMorgan Research Market Neutral Fund

JPMorgan Research Market Neutral Fund

Class/Ticker: L/JPMNX

Until December 1, 2016, the Class L Shares were named Institutional Class Shares. Currently, Class L Shares of the Fund are publicly offered only on a limited basis. (See “Investing with J.P. Morgan Funds — LIMITED OFFERING OF THE CLASS L SHARES” in the prospectus for more information.)

What is the goal of the Fund?

The Fund seeks to provide long-term capital appreciation from a broadly diversified portfolio of U.S. stocks while neutralizing the general risks associated with stock market investing.

Fees and Expenses of the Fund

The following tables describe the fees and expenses that you may pay if you buy and hold shares of the Fund. “Acquired Fund Fees and Expenses” are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies, including affiliated money market funds, other mutual funds, exchange-traded funds and business development companies. The impact of Acquired Fund Fees and Expenses is included in the total returns of the Fund. Acquired Fund Fees and Expenses are not direct costs of the Fund, are not used to calculate the Fund’s net asset value per share and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus.

ANNUAL FUND OPERATING EXPENSES
(Expenses that you pay each year as a percentage of the value
of your investment)

Annual Fund Operating Expenses	L Shares JPMorgan Research Market Neutral Fund Class L
Management Fees	0.80%
Distribution (Rule 12b-1) Fees	none

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. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 2/28/18 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

WHETHER OR NOT YOU SELL YOUR SHARES, YOUR
COST WOULD BE:

Expense Example	1 Year	3 Years	5 Years	10 Years
L Shares | JPMorgan Research Market Neutral Fund | CLASS L SHARES | USD ($)	299	960	1,645	3,470

WHETHER OR NOT YOU SELL YOUR SHARES, YOUR
COST WOULD BE:

Expense Example, No Redemption	1 Year	3 Years	5 Years	10 Years
L Shares | JPMorgan Research Market Neutral Fund | CLASS L SHARES | USD ($)	299	960	1,645	3,470

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. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate (including short sales) was 298% of the average value of its portfolio.

What are the Fund’s main investment strategies?

The Fund takes long and short positions in different securities, selecting from a universe of mid- to large-capitalization stocks with characteristics similar to those of the Russell 1000 and/or Standard & Poor’s 500 (S&P 500) Indexes, in an effort to insulate the Fund’s performance from the effects of general stock market movements. As of the last reconstitution of the Russell 1000 Index on June 24, 2016, the companies in the index included companies with market capitalizations ranging from $1.5 billion to $504.1 billion. As of the last reconstitution of the S&P 500 Index on September 30, 2016, the companies in the index included companies with market capitalizations of $1.1 billion to $609.2 billion.

In rising markets, the Fund expects that the long positions will appreciate more rapidly than the short positions, and in declining markets that the short positions will decline faster than the long positions. The Fund expects that this difference in rates of appreciation, along with any returns on cash generated by short sales, will generate a positive return; the Fund pursues returns exceeding those of 90-day U.S. Treasury Bills.

The Fund purchases securities that it believes are undervalued and sells short securities that it believes are overvalued. The long and short positions are matched on a variety of risk characteristics in order to limit exposure to macroeconomic factors.

In each sector in which the Fund invests, it balances the dollars invested in long and short positions to remain sector neutral. In attempting to neutralize market and sector risks, the Fund emphasizes stock selection as the primary means of generating returns.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. The Fund may use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: In managing the Fund the adviser employs a three-step process that combines research, valuation and stock selection.

The research findings allow the adviser to rank the companies according to what it believes to be their relative value. The greater a company’s estimated worth compared to the current market price of its stock, the more undervalued the company. The valuation rankings are produced with the help of a variety of models that quantify the research team’s findings.

The Fund buys and sells securities according to its own policies, using the research and valuation rankings as a basis. In general, the team selects securities that are identified as undervalued and considers selling them when they appear overvalued. Along with attractive valuation, the team often considers a number of other criteria:

• catalysts that could trigger a rise in a stock’s price

• impact on the overall risk of the portfolio relative to the benchmark

• temporary mispricings caused by market overreactions

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 instruments 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Strategy Risk. There is no guarantee that the use of long and short positions will succeed in limiting the Fund’s exposure to domestic stock market movements, capitalization, sector-swings or other risk factors.

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. When the value of the Fund’s securities goes down, the value of your investment in the Fund decreases in value.

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. Securities in the Fund’s portfolio may underperform securities in comparison to general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

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 the short sale and the date on which the Fund purchases the security to replace the borrowed security. In addition, a lender may request, or market conditions may dictate, that securities sold short be returned to the lender on short notice, and the Fund may have to buy the securities sold short at an unfavorable price. If this occurs, any anticipated gain to the Fund may be reduced or eliminated or the short sale may result in a loss. The Fund’s losses are potentially unlimited in a short sale transaction. 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.

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.

Derivatives Risk. Derivatives, including futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including the credit risk of the derivative counterparty. 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. Certain of the Fund’s transactions in derivatives could also affect the amount, timing and character of distributions to shareholders which may result in the Fund realizing more short-term capital gain and ordinary income subject to tax at ordinary income tax rates than it would if it did not engage in such transactions, which may adversely impact the Fund’s after-tax returns.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

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.

The Fund’s Past Performance

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. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 2/28/18, and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

IF YOU SELL YOUR SHARES, YOUR COST WOULD BE:

Expense Example - A, C, Select Shares - JPMorgan Opportunistic Equity Long/Short Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	748	1,241	1,759	3,173
CLASS C SHARES	385	908	1,557	3,296
SELECT CLASS SHARES	210	680	1,176	2,543

IF YOU DO NOT SELL YOUR SHARES, YOUR COST
WOULD BE:

Expense Example, No Redemption - A, C, Select Shares - JPMorgan Opportunistic Equity Long/Short Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	748	1,241	1,759	3,173
CLASS C SHARES	285	908	1,557	3,296
SELECT CLASS SHARES	210	680	1,176	2,543

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. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate (including short sales) was 749% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal circumstances, the Fund will invest at least 80% of its Assets in long and short positions in equity securities, selecting from a universe of equity securities with market capitalizations similar to those included in the Russell 1000 and/or S&P 500 Index, at the time of purchase. As of the reconstitution of the Russell 1000 Index on June 24, 2016, the companies in the index included companies with market capitalizations ranging from $1.5 billion to $504.1 billion. As of the reconstitution of the S&P 500 Index on September 30, 2016 the companies in the index included companies with market capitalizations of $1.1 billion to $609.2 billion. “Assets” means net assets plus the amount of borrowings for investment purposes.

Part of the Fund’s investment strategy is to attempt to achieve lower volatility than that of its primary benchmark, the S&P 500 Index. Volatility management starts during the stock selection research process before inclusion in the portfolio. The Fund’s adviser will employ a number of strategies to manage the Fund’s volatility, including altering the Fund’s portfolio composition, adjusting the Fund’s gross exposure or net exposure, holding significant cash balances, or investing in options (to attempt to limit losses from stock positions).

In implementing its strategy, the Fund primarily will buy or sell short common stocks, including real estate investment trusts (REITs) and depositary receipts.

As the set of investment opportunities is constantly evolving, the Fund’s net exposure (the value of the Fund’s aggregate long positions minus its short positions) will vary over time. While in most instances the net exposure will be positive (more long exposure than short exposure), it is possible that the investment opportunities result in a net short exposure. Net exposure will range from -30% to +80%. The Fund’s gross equity market exposure is limited to 200%.

Short sales involve the sale of a security which the Fund does not own in hopes of purchasing the same security at a later date at a lower price. To make delivery to the buyer, the Fund must borrow the security, and the Fund is obligated to return the security to the lender, which is accomplished by a later purchase of the security by the Fund.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use equity index futures contracts and options, both long and short, to gain or reduce exposure to specific investments or the overall equity market. The Fund may also invest in exchange traded funds (ETFs) for these purposes.

The Fund is non-diversified.

Investment Process: J.P. Morgan Investment Management Inc., the Fund’s adviser, employs a process that combines research, valuation and stock selection to identify investments. Long and short positions are vetted through a disciplined research process and valuation framework which leverages the insights of the adviser’s fundamental analyst platform that actively analyzes approximately 800 stocks. The adviser buys long positions in companies with strong management teams, strong competitive positions and earnings growth rates in excess of peers. Long purchases may also be companies that the adviser believes have improving investment factors, such as business drivers (revenues, profitability, capital intensity, and capital allocation), industry structure, regulatory environment and/or legal risk. Short sales generally are characterized by companies with deteriorating incremental changes in such investment factors. The adviser may also take short positions as part of its volatility management. The adviser may sell a long position or cover a short position due to a change in the company’s fundamentals, a change in the original reason for purchase of an investment, or if the adviser no longer considers the security to be reasonably valued. Investments may also be sold or covered if the adviser identifies another investment that it believes offers a better opportunity.

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 instruments 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

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. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

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. Securities in the Fund’s portfolio may underperform securities in comparison to general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

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 the short sale and the date on which the Fund purchases the security to replace the borrowed security. In addition, a lender may request, or market conditions may dictate, that securities sold short be returned to the lender on short notice, and the Fund may have to buy the securities sold short at an unfavorable price. If this occurs, any anticipated gain to the Fund may be reduced or eliminated or the short sale may result in a loss. The Fund’s losses are potentially unlimited in a short sale transaction. 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.

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 credit-worthiness 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.

ETF and Investment Company Risk. The Fund may invest in shares of other investment companies, including ETFs. Shareholders will indirectly bear the expenses charged by the underlying ETFs. The price movement of an index-based ETF may not track the underlying index and may result in a loss. ETFs and closed-end investment companies may trade at a price below their net asset value (also known as a discount).

Derivatives Risk. Derivatives, including futures and options, 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 expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). 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. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Depositary Receipts Risk. The Fund’s investments may take the form of depositary receipts, including unsponsored depositary receipts. 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, sanctions and other measures by the United States or other governments, currency fluctuations, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign 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. Unsponsored depositary receipts may not provide as much information about the underlying issuer and may not carry the same voting privileges as sponsored depositary receipts. Unsponsored depositary receipts are issued by one or more depositaries in response to market demand, but without a formal agreement with the company that issues the underlying securities.

High Portfolio Turnover Risk. The Fund may 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.

Non-Diversified Fund Risk. Since the Fund is non-diversified, it may invest a greater percentage of its assets in a particular issuer or group of issuers than a diversified fund would. This increased investment in fewer issuers may result in the Fund’s shares being more sensitive to economic results among those issuing the securities.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

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.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund will invest at least 80% of its Assets in long and short positions in equity securities, selecting from a universe of equity securities with market capitalizations similar to those included in the Russell 1000 and/or S&P 500 Index, at the time of purchase. As of the reconstitution of the Russell 1000 Index on June 24, 2016, the companies in the index included companies with market capitalizations ranging from $1.5 billion to $504.1 billion. As of the reconstitution of the S&P 500 Index on September 30, 2016 the companies in the index included companies with market capitalizations of $1.1 billion to $609.2 billion. “Assets” means net assets plus the amount of borrowings for investment purposes.

Part of the Fund’s investment strategy is to attempt to achieve lower volatility than that of its primary benchmark, the S&P 500 Index. Volatility management starts during the stock selection research process before inclusion in the portfolio. The Fund’s adviser will employ a number of strategies to manage the Fund’s volatility, including altering the Fund’s portfolio composition, adjusting the Fund’s gross exposure or net exposure, holding significant cash balances, or investing in options (to attempt to limit losses from stock positions).

In implementing its strategy, the Fund primarily will buy or sell short common stocks, including real estate investment trusts (REITs) and depositary receipts.

As the set of investment opportunities is constantly evolving, the Fund’s net exposure (the value of the Fund’s aggregate long positions minus its short positions) will vary over time. While in most instances the net exposure will be positive (more long exposure than short exposure), it is possible that the investment opportunities result in a net short exposure. Net exposure will range from -30% to +80%. The Fund’s gross equity market exposure is limited to 200%.

Short sales involve the sale of a security which the Fund does not own in hopes of purchasing the same security at a later date at a lower price. To make delivery to the buyer, the Fund must borrow the security, and the Fund is obligated to return the security to the lender, which is accomplished by a later purchase of the security by the Fund.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use equity index futures contracts and options, both long and short, to gain or reduce exposure to specific investments or the overall equity market. The Fund may also invest in exchange traded funds (ETFs) for these purposes.

The Fund is non-diversified.

Investment Process: J.P. Morgan Investment Management Inc., the Fund’s adviser, employs a process that combines research, valuation and stock selection to identify investments. Long and short positions are vetted through a disciplined research process and valuation framework which leverages the insights of the adviser’s fundamental analyst platform that actively analyzes approximately 800 stocks. The adviser buys long positions in companies with strong management teams, strong competitive positions and earnings growth rates in excess of peers. Long purchases may also be companies that the adviser believes have improving investment factors, such as business drivers (revenues, profitability, capital intensity, and capital allocation), industry structure, regulatory environment and/or legal risk. Short sales generally are characterized by companies with deteriorating incremental changes in such investment factors. The adviser may also take short positions as part of its volatility management. The adviser may sell a long position or cover a short position due to a change in the company’s fundamentals, a change in the original reason for purchase of an investment, or if the adviser no longer considers the security to be reasonably valued. Investments may also be sold or covered if the adviser identifies another investment that it believes offers a better opportunity.

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 instruments 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

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. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

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. Securities in the Fund’s portfolio may underperform securities in comparison to general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

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 the short sale and the date on which the Fund purchases the security to replace the borrowed security. In addition, a lender may request, or market conditions may dictate, that securities sold short be returned to the lender on short notice, and the Fund may have to buy the securities sold short at an unfavorable price. If this occurs, any anticipated gain to the Fund may be reduced or eliminated or the short sale may result in a loss. The Fund’s losses are potentially unlimited in a short sale transaction. 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.

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 credit-worthiness 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.

ETF and Investment Company Risk. The Fund may invest in shares of other investment companies, including ETFs. Shareholders will indirectly bear the expenses charged by the underlying ETFs. The price movement of an index-based ETF may not track the underlying index and may result in a loss. ETFs and closed-end investment companies may trade at a price below their net asset value (also known as a discount).

Derivatives Risk. Derivatives, including futures and options, 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 expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). 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. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Depositary Receipts Risk. The Fund’s investments may take the form of depositary receipts, including unsponsored depositary receipts. 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, sanctions and other measures by the United States or other governments, currency fluctuations, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign 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. Unsponsored depositary receipts may not provide as much information about the underlying issuer and may not carry the same voting privileges as sponsored depositary receipts. Unsponsored depositary receipts are issued by one or more depositaries in response to market demand, but without a formal agreement with the company that issues the underlying securities.

High Portfolio Turnover Risk. The Fund may 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.

Non-Diversified Fund Risk. Since the Fund is non-diversified, it may invest a greater percentage of its assets in a particular issuer or group of issuers than a diversified fund would. This increased investment in fewer issuers may result in the Fund’s shares being more sensitive to economic results among those issuing the securities.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

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.

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. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 2/28/18, and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

WHETHER OR NOT YOU SELL YOUR SHARES, YOUR
COST WOULD BE:

CLASS R5 SHARES	190	1,069	1,962	4,255
CLASS R6 SHARES	185	637	1,116	2,438

WHETHER OR NOT YOU SELL YOUR SHARES, YOUR
COST WOULD BE:

Expense Example, No Redemption - R2, R5, R6 Shares - JPMorgan Opportunistic Equity Long/Short Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
CLASS R2 SHARES	260	1,261	2,264	4,783
CLASS R5 SHARES	190	1,069	1,962	4,255
CLASS R6 SHARES	185	637	1,116	2,438

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. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate (including short sales) was 749% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal circumstances, the Fund will invest at least 80% of its Assets in long and short positions in equity securities, selecting from a universe of equity securities with market capitalizations similar to those included in the Russell 1000 and/or S&P 500 Index, at the time of purchase. As of the reconstitution of the Russell 1000 Index on June 24, 2016, the companies in the index included companies with market capitalizations ranging from $1.5 billion to $504.1 billion. As of the reconstitution of the S&P 500 Index on September 30, 2016 the companies in the index included companies with market capitalizations of $1.1 billion to $609.2 billion. “Assets” means net assets plus the amount of borrowings for investment purposes.

Part of the Fund’s investment strategy is to attempt to achieve lower volatility than that of its primary benchmark, the S&P 500 Index. Volatility management starts during the stock selection research process before inclusion in the portfolio. The Fund’s adviser will employ a number of strategies to manage the Fund’s volatility, including altering the Fund’s portfolio composition, adjusting the Fund’s gross exposure or net exposure, holding significant cash balances, or investing in options (to attempt to limit losses from stock positions).

In implementing its strategy, the Fund primarily will buy or sell short common stocks, including real estate investment trusts (REITs) and depositary receipts.

As the set of investment opportunities is constantly evolving, the Fund’s net exposure (the value of the Fund’s aggregate long positions minus its short positions) will vary over time. While in most instances the net exposure will be positive (more long exposure than short exposure), it is possible that the investment opportunities result in a net short exposure. Net exposure will range from -30% to +80%. The Fund’s gross equity market exposure is limited to 200%.

Short sales involve the sale of a security which the Fund does not own in hopes of purchasing the same security at a later date at a lower price. To make delivery to the buyer, the Fund must borrow the security, and the Fund is obligated to return the security to the lender, which is accomplished by a later purchase of the security by the Fund.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use equity index futures contracts and options, both long and short, to gain or reduce exposure to specific investments or the overall equity market. The Fund may also invest in exchange traded funds (ETFs) for these purposes.

The Fund is non-diversified.

Investment Process: J.P. Morgan Investment Management Inc., the Fund’s adviser, employs a process that combines research, valuation and stock selection to identify investments. Long and short positions are vetted through a disciplined research process and valuation framework which leverages the insights of the adviser’s fundamental analyst platform that actively analyzes approximately 800 stocks. The adviser buys long positions in companies with strong management teams, strong competitive positions and earnings growth rates in excess of peers. Long purchases may also be companies that the adviser believes have improving investment factors, such as business drivers (revenues, profitability, capital intensity, and capital allocation), industry structure, regulatory environment and/or legal risk. Short sales generally are characterized by companies with deteriorating incremental changes in such investment factors. The adviser may also take short positions as part of its volatility management. The adviser may sell a long position or cover a short position due to a change in the company’s fundamentals, a change in the original reason for purchase of an investment, or if the adviser no longer considers the security to be reasonably valued. Investments may also be sold or covered if the adviser identifies another investment that it believes offers a better opportunity.

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 instruments 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

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. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

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. Securities in the Fund’s portfolio may underperform securities in comparison to general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

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 the short sale and the date on which the Fund purchases the security to replace the borrowed security. In addition, a lender may request, or market conditions may dictate, that securities sold short be returned to the lender on short notice, and the Fund may have to buy the securities sold short at an unfavorable price. If this occurs, any anticipated gain to the Fund may be reduced or eliminated or the short sale may result in a loss. The Fund’s losses are potentially unlimited in a short sale transaction. 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.

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 credit-worthiness 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.

ETF and Investment Company Risk. The Fund may invest in shares of other investment companies, including ETFs. Shareholders will indirectly bear the expenses charged by the underlying ETFs. The price movement of an index-based ETF may not track the underlying index and may result in a loss. ETFs and closed-end investment companies may trade at a price below their net asset value (also known as a discount).

Derivatives Risk. Derivatives, including futures and options, 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 expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). 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. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Depositary Receipts Risk. The Fund’s investments may take the form of depositary receipts, including unsponsored depositary receipts. 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, sanctions and other measures by the United States or other governments, currency fluctuations, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign 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. Unsponsored depositary receipts may not provide as much information about the underlying issuer and may not carry the same voting privileges as sponsored depositary receipts. Unsponsored depositary receipts are issued by one or more depositaries in response to market demand, but without a formal agreement with the company that issues the underlying securities.

High Portfolio Turnover Risk. The Fund may 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.

Non-Diversified Fund Risk. Since the Fund is non-diversified, it may invest a greater percentage of its assets in a particular issuer or group of issuers than a diversified fund would. This increased investment in fewer issuers may result in the Fund’s shares being more sensitive to economic results among those issuing the securities.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

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.

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. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate (including short sales) was 749% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund will invest at least 80% of its Assets in long and short positions in equity securities, selecting from a universe of equity securities with market capitalizations similar to those included in the Russell 1000 and/or S&P 500 Index, at the time of purchase. As of the reconstitution of the Russell 1000 Index on June 24, 2016, the companies in the index included companies with market capitalizations ranging from $1.5 billion to $504.1 billion. As of the reconstitution of the S&P 500 Index on September 30, 2016 the companies in the index included companies with market capitalizations of $1.1 billion to $609.2 billion. “Assets” means net assets plus the amount of borrowings for investment purposes.

Part of the Fund’s investment strategy is to attempt to achieve lower volatility than that of its primary benchmark, the S&P 500 Index. Volatility management starts during the stock selection research process before inclusion in the portfolio. The Fund’s adviser will employ a number of strategies to manage the Fund’s volatility, including altering the Fund’s portfolio composition, adjusting the Fund’s gross exposure or net exposure, holding significant cash balances, or investing in options (to attempt to limit losses from stock positions).

In implementing its strategy, the Fund primarily will buy or sell short common stocks, including real estate investment trusts (REITs) and depositary receipts.

As the set of investment opportunities is constantly evolving, the Fund’s net exposure (the value of the Fund’s aggregate long positions minus its short positions) will vary over time. While in most instances the net exposure will be positive (more long exposure than short exposure), it is possible that the investment opportunities result in a net short exposure. Net exposure will range from -30% to +80%. The Fund’s gross equity market exposure is limited to 200%.

Short sales involve the sale of a security which the Fund does not own in hopes of purchasing the same security at a later date at a lower price. To make delivery to the buyer, the Fund must borrow the security, and the Fund is obligated to return the security to the lender, which is accomplished by a later purchase of the security by the Fund.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use equity index futures contracts and options, both long and short, to gain or reduce exposure to specific investments or the overall equity market. The Fund may also invest in exchange traded funds (ETFs) for these purposes.

The Fund is non-diversified.

Investment Process: J.P. Morgan Investment Management Inc., the Fund’s adviser, employs a process that combines research, valuation and stock selection to identify investments.

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular instruments 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.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

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. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

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. Securities in the Fund’s portfolio may underperform securities in comparison to general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation, interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

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 the short sale and the date on which the Fund purchases the security to replace the borrowed security. In addition, a lender may request, or market conditions may dictate, that securities sold short be returned to the lender on short notice, and the Fund may have to buy the securities sold short at an unfavorable price.
