Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in 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 71% 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 seeks to achieve its investment objective by investing across sectors in developed and emerging markets located around the world. The Fund is flexible and opportunistic. Because the Fund is not managed to a benchmark, J.P. Morgan Investment Management Inc. (JPMIM or the adviser) has broad discretion to shift the Fund’s exposure to strategies, sectors, countries or currencies based on changing market conditions and its view of the best mix of investment opportunities. In buying and selling investments for the Fund, the adviser allocates the Fund’s exposure to strategies, sectors, countries, and currencies based on the adviser’s analysis of individual investments and broader economic conditions in individual countries, regions and the world. This allows the adviser to take a conservative approach during uncertain periods and move into higher risk opportunities as market conditions improve, which may result in the Fund focusing in only a few markets and sectors. The Fund’s focus may change from time to time.

Under normal circumstances, the Fund will invest at least 80% of its Assets in bonds. “Assets” means net assets plus the amount of borrowings for investment purposes. Under normal circumstances, the Fund will invest at least 40% of its total assets in countries other than the United States. The Fund may invest in developed or emerging markets. Emerging markets currently includes most countries in the world except Australia, Canada, Japan, New Zealand, the U.S., the United Kingdom and most western European countries and Hong Kong. In managing the Fund, the adviser will invest in issuers in at least three countries other than the U.S. The Fund may invest a substantial part of its assets in just one country and is not required to allocate its investments in any set percentages in any particular countries. Currently, the Fund anticipates that it will invest no more than 50% of its total assets in non-dollar denominated securities but may invest more from time to time to take advantage of market conditions.

Although the Fund has the flexibility to invest without limit in securities that are rated below investment grade (also known as junk bonds or high yield securities), or the unrated equivalent, the Fund generally invests at least 25% of the Fund's total assets in investments that, at the time of purchase are rated investment grade or the unrated equivalent. The Fund has flexibility to decrease the percentage of assets invested in investment grade securities at any time to take advantage of higher risk opportunities when market conditions are improving.

The Fund has broad flexibility to invest in a wide variety of debt securities and instruments. The Fund currently seeks to maintain a duration of eight years or less, although the Fund has the flexibility to maintain a longer duration under certain market conditions such as significant volatility in interest rates and spreads. Duration is a measure of the price sensitivity of a debt security or a portfolio of debt securities to relative changes in interest rates. For instance, a duration of three years means that a security’s or portfolio’s price would be expected to decrease by approximately 3% with a 1% increase in interest rates (assuming a parallel shift in yield curve). As part of its principal investment strategy, the Fund may invest in fixed and floating rate debt securities issued in developed and emerging markets. These securities may include debt securities issued by governments and their agencies, state and provincial governmental entities, supranational organizations, corporations, and banks.

The Fund may also use currency-related transactions involving currency derivatives as part of its primary investment strategy. A derivative is an instrument that has a value based on another instrument, exchange rate or index. The Fund may use currency derivatives including foreign forward currency contracts (including non-deliverable forwards) and currency options for hedging or to gain or manage exposure to currencies or securities. The adviser has flexibility to significantly increase the Fund’s exposure to securities or currencies through the use of currency derivatives. The Fund is not required to hedge its non-dollar investment back to the U.S. dollar through the use of derivatives, but may do so from time to time as part of its strategy.

In addition to currency derivatives, the Fund may use other fixed income and credit derivatives including futures contracts, options, and swaps (including credit default swaps). The Fund may use derivatives as substitutes for securities in which the Fund can invest. The Fund may also use derivatives for hedging purposes (for example, to take synthetic short positions to decrease exposure to certain securities, markets or currencies), to seek to increase 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.

A significant portion of the Fund’s assets may be invested in asset-backed, mortgage-related and mortgage-backed securities. Such securities may be structured as collateralized mortgage obligations and stripped mortgage-backed securities, including those structured such that payments consist of interest-only (IO), principal-only (PO) or principal and interest. The Fund may also invest in structured investments including credit linked notes (CLNs) for which the reference instrument is an emerging markets or developed markets debt instrument, adjustable rate mortgage loans (ARMs), and custodial receipts. The Fund may invest a significant amount of its assets in “sub-prime” mortgage-related securities.

The Fund may invest in securities issued by the U.S. government and its agencies and instrumentalities including U.S. Treasury securities, treasury receipts and obligations and securities issued by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) and the Federal Home Loan Mortgage Corporation (Freddie Mac).

The Fund may invest in mortgage pass-through securities including mortgage securities eligible to be sold in the “to-be-announced” or TBA market (Mortgage TBAs). The Fund may enter into dollar rolls, in which the Fund sells mortgage-backed securities including mortgage TBAs and at the same time contracts to buy back very similar securities on a future date. The Fund may also sell mortgage TBAs short.

The Fund may invest in inflation-linked debt securities including fixed and floating rate debt securities of varying maturities issued by the U.S. government, its agencies and instrumentalities, such as Treasury Inflation Protected Securities (TIPS). The Fund may also invest in inflation-linked debt securities issued by other entities such as corporations, foreign governments and foreign issuers.

The Fund may also invest in synthetic variable rate instruments, when-issued securities, delayed delivery securities, forward commitments, zero-coupon securities, pay-in-kind securities, inverse floating rate securities, short-term funding agreements, and deferred payment securities.

As part of its principal investment strategy and for temporary defensive purposes, any portion of the Fund’s total assets may be invested in cash and cash equivalents.
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.

Foreign Securities and Emerging Markets Risk. U.S. dollar-denominated securities of foreign issuers or U.S. affiliates of foreign issuers may be subject to additional risks not faced by domestic issuers. These risks include 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, and regulatory issues facing issuers in such countries. The Fund may also invest in non-dollar denominated securities. Investments in non-dollar denominated securities are subject to risks in addition to those summarized above including currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, liquidity risks, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payments,” 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 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.

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 these investments generally declines. Securities with greater interest rate sensitivity and long 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 other fixed rate instruments, the value of floating rate securities may decline if their interest rates do not raise as quickly, or as much, as general interest rates. Given the historically low interest rate environment, risks associated with rising rates are heightened. Securities with greater interest rate sensitivity and longer maturities tend to produce higher yields, but are subject to greater fluctuations in value.

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.

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 action 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.

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.

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.

Sovereign Debt Risk. The Fund may invest in securities issued or guaranteed by foreign governmental entities (known as sovereign debt securities). These 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 in that country loses value because that currency is worth fewer 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.

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

Derivatives Risk. Derivatives, including foreign forward currency contracts, options, futures contracts and swaps, 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). 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.

Strategy Risk. The Fund uses a flexible asset allocation approach which may result in the adviser focusing on only a few strategies, sectors, countries or currencies. Due to the Fund’s flexible allocation approach, the Fund’s risk exposure may vary and risk associated with an individual strategy, sector, country or currency may become more pronounced particularly when the Fund utilizes only a few strategies or types of investments. The Fund’s currency management strategies may substantially change the Fund’s exposure to currency exchange rates and could result in losses to the Fund if currencies do not perform as the adviser expects. In addition, currency management strategies, to the extent that they reduce the Fund’s exposure to currency risks, may also reduce the Fund’s ability to benefit from favorable changes in currency exchange rates. Using currency derivative strategies for purposes other than hedging further increases the Fund’s exposure to foreign investment losses. Currency markets generally are not as regulated as securities markets. In addition, currency rates may fluctuate significantly over short periods of time, and can reduce returns.

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 Ginnie Mae, Fannie Mae, or 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.

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 interest-only (IOs) and principal-only (POs), are more volatile and may be more sensitive to the rate of prepayments than other mortgage-related securities. The risk of default, as described under “Credit Risk”, for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.

Prepayment Risk. The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or 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 coupons, resulting in an unexpected capital loss.

Structured Investment Risk. Certain structured investments including CLNs are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such instruments, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

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.

Mortgage Dollar Roll Risk. The Fund may enter into mortgage dollar rolls involving mortgage pass-through securities including mortgage TBAs and other mortgage-backed securities. During the period between the sale and repurchase in a mortgage dollar roll transaction, the Fund will not be entitled to receive interest and principal payments on the securities sold. Losses may arise due to changes in the value of the securities or if the counterparty does not perform under the terms of the agreement. If the counterparty files for bankruptcy or becomes insolvent, the Fund’s right to repurchase or sell securities may be limited. Short sales of Mortgage TBAs and engaging in mortgage dollar rolls may be subject to leverage risks as described under “Derivatives Risk.” In addition, mortgage dollar rolls may increase interest rate risk and result in an increased portfolio turnover rate which increases costs and may increase taxable gains.

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.

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.
