What are the Fund’s main investment strategies?

Summary of Definition of Rule 35d-1 Term in Fund Name [Text Block]

As part of its main investment strategy, the Fund may principally invest in corporate bonds, U.S. treasury obligations and other U.S. government and agency securities, and asset-backed, mortgage-related and mortgage-backed securities. The Fund also may invest in bonds, convertible securities, preferred stock, loan participations and assignments (Loans) and commitments to purchase loan assignments (Unfunded Commitments), and foreign and emerging market debt securities rated below investment grade (i.e., high yield or junk bonds) or the unrated equivalent. The "unrated equivalent" refers to securities that are unrated but deemed by the adviser to be of comparable quality. As a matter of fundamental policy, the Fund will invest at least 80% of its Assets in bonds. In addition, under normal circumstances, the Fund will invest at least 80% of its Assets in “core plus bonds,” defined as U.S. investment grade (or the unrated equivalent), U.S. below investment grade (or the unrated equivalent), and foreign and emerging markets bonds (either investment grade or below investment grade (or their unrated equivalents)). For purposes of these policies, a “bond” is a debt security with a maturity of 90 days or more at the time of its issuance. “Assets” means net assets plus the amount of borrowings for investment purposes. The Fund’s average weighted maturity will ordinarily range between five and twenty years. The Fund may have a longer or shorter average weighted maturity under certain market conditions and the Fund may shorten or lengthen its average weighted maturity if deemed appropriate for temporary defensive purposes. Because of the Fund’s holdings in asset-backed, mortgage-backed and similar securities, the Fund’s average weighted maturity is equivalent to the average weighted maturity of the cash flows in the securities held by the Fund given certain prepayment assumptions (also known as weighted average life). The adviser will invest across the credit spectrum to provide the Fund exposure to various credit rating categories. Under normal conditions, at least 70% of the Fund’s total assets must be invested in securities that, at the time of purchase, are rated investment grade by a nationally recognized statistical rating organization or in securities that are unrated but are deemed by the adviser to be of comparable quality. The balance of the Fund’s assets are not required to meet any minimum quality rating although the Fund will not, under normal circumstances, invest more than 30% of its total assets in below investment grade securities (or the unrated equivalent). Such securities may include so called “distressed debt.” Distressed debt includes securities of issuers experiencing financial or operating difficulties, securities where the issuer has defaulted in the payment of interest or principal or in the performance of its covenants or agreements, securities of issuers that may be involved in bankruptcy proceedings, reorganizations or financial restructurings or securities of issuers operating in troubled industries. The Fund may also invest in loan assignments and participations (Loans) and commitments to purchase loan assignments (Unfunded Commitments) including below investment grade Loans and Unfunded Commitments. Loans will typically consist of senior floating rate loans (Senior Loans), but may also include secured and unsecured loans, second lien loans or more junior (Junior Loans) and bridge loans. Loans may be issued by obligors in the U.S. or in foreign or emerging markets. The Fund may invest a significant portion of all of its assets in mortgage-related and mortgage-backed securities at the adviser’s discretion. Mortgage-related and mortgage-backed securities may be structured as collateralized mortgage obligations (agency and non-agency), stripped mortgage-backed securities (interest-only or principal-only), commercial mortgage-backed securities, mortgage pass-through securities and cash and cash equivalents. The Fund expects to invest no more than 10% of its assets in “sub-prime” mortgage-related securities at the time of purchase. The Fund may also enter into “dollar rolls” in which the Fund sells mortgage-backed securities and at the same time contracts to buy back very similar securities on a future date. Up to 25% of the Fund’s Assets may be invested in foreign securities, including securities denominated in foreign currencies (some of which may be below investment grade securities). Foreign securities include securities issued by foreign governments or their agencies and instrumentalities and companies that are incorporated outside the United States, including securities from issuers in countries whose economies are less developed (emerging markets), but do not include collateralized loan obligations (CLOs) that are denominated in U.S. dollars. The Fund’s investments in below investment grade securities or the unrated equivalent including below investment grade foreign securities will not, under normal circumstances, exceed more than 30% of the Fund’s total assets. 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, options, swaps and forward contracts as tools in the management of portfolio assets. The Fund may use derivatives to hedge various investments, for risk management and/or to increase income or gain to the Fund. In addition to the mortgage dollar rolls as described above, the Fund may utilize other relative value strategies involving credit-oriented trades, combinations of derivatives, and combinations of derivatives and fixed income securities. The Fund may also utilize foreign currency derivatives such as currency forwards to hedge its non-dollar investments back to the U.S. dollar or use such derivatives to gain or adjust exposure to particular foreign securities, markets or currencies. The adviser allocates the Fund’s assets among a range of sectors based on strategic positioning and other tactical considerations. In buying and selling investments for the Fund, the adviser looks for market sectors and individual securities that it believes will perform well over time. The adviser selects individual securities after performing a risk/reward analysis that includes an evaluation of interest rate risk, credit risk, currency risk, legal provisions and the structure of the transactions. With respect to the high yield portion of the Fund, the adviser focuses on value in choosing securities for the Fund by looking at individual securities against the context of broader market factors. As part of its investment process, the adviser seeks to assess the impact of environmental, social and governance (ESG) factors on certain issuers or countries in the universe in which the Fund may invest. The adviser’s assessment is based on an analysis of key opportunities and risks across industries to seek to identify financially material issues with respect to the Fund’s investments in issuers and ascertain key issues that merit engagement with issuers. These assessments may not be conclusive and securities of issuers or countries that may be negatively impacted by such factors may be purchased and retained by the Fund while the Fund may divest or not invest in securities of issuers or countries that may be positively impacted by such factors. The Fund may enter into lending agreements under which the Fund would lend money for temporary purposes directly to another J.P. Morgan Fund through a credit facility, subject to meeting the conditions of an SEC exemptive order granted to the Fund permitting such interfund lending.

In addition, under normal circumstances, the Fund will invest at least 80% of its Assets in “core plus bonds,” defined as U.S. investment grade (or the unrated equivalent), U.S. below investment grade (or the unrated equivalent), and foreign and emerging markets bonds (either investment grade or below investment grade (or their unrated equivalents)). For purposes of these policies, a “bond” is a debt security with a maturity of 90 days or more at the time of its issuance. “Assets” means net assets plus the amount of borrowings for investment purposes.

Summary of Definition of Rule 35d-1 Term in Fund Name [Text Block]

The Fund principally invests in securities issued by the U.S. government and its agencies and instrumentalities and related to securities issued by the U.S. government and its agencies and instrumentalities. The Fund may also invest in securities which are guaranteed by the U.S. government and its agencies and instrumentalities so long as such securities are backed by the full faith and credit of the United States.The Fund mainly invests in government bonds with intermediate to long remaining maturities. These include U.S. mortgage-backed securities, including those issued or guaranteed by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac). Mortgage-backed securities may be structured as collateralized mortgage obligations (agency and non-agency), mortgage pass-though securities, and stripped mortgage-backed securities. These securities may be structured such that payments consist of interest-only (IO), principal-only (PO) or principal and interest. The Fund may invest a significant portion or all of its assets in mortgage-backed securities in the adviser’s discretion. Under normal circumstances, the Fund will invest at least 80% of its Assets in government bonds including bonds issued or guaranteed by the U.S. government and its agencies and instrumentalities. For purposes of this policy, “Assets” means net assets plus the amount of borrowings for investment purposes. Ordinarily, such bonds will have principal and interest guaranteed by the U.S. government or its agencies and instrumentalities, be subject to repurchase agreements, or represent an interest in or be secured by mortgages that are issued or guaranteed by certain U.S. government agencies or instrumentalities. The Fund’s average weighted maturity will ordinarily range between three and 15 years, taking into account expected prepayment of principal on certain investments. The Fund may have a longer or shorter average weighted maturity under certain market conditions and the Fund may shorten or lengthen its average weighted maturity if deemed appropriate for temporary defensive purposes. Because of the Fund’s holdings in mortgage-backed and similar securities, the Fund’s average weighted maturity is equivalent to the average number of years for which each dollar of unpaid principal on a loan or mortgage securing mortgage-backed and similar securities remains outstanding given certain prepayment assumptions (also known as weighted average life). The Fund’s adviser has flexibility with respect to the Fund’s duration. Currently, the Fund’s adviser aims to maintain a duration of between 5.00 and 5.50 years over the long term, although the adviser has the flexibility to maintain a longer or shorter duration when it believes it is advisable to do so. 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). The adviser buys and sells securities and investments for the Fund based on its view of individual securities and market 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, legal provisions and the structure of the transaction. As part of its evaluation of credit risk, the adviser seeks to assess the impact of environmental, social and governance (ESG) factors on certain issuers in the universe in which the Fund may invest. The adviser’s assessment is based on an analysis of key opportunities and risks across industries to seek to identify financially material issues with respect to the Fund’s investments in issuers and ascertain key issues that merit engagement with issuers. These assessments may not be conclusive and securities of issuers that may be negatively impacted by such factors may be purchased and retained by the Fund while the Fund may divest or not invest in securities of issuers that may be positively impacted by such factors.

The Fund invests in all types of high yield, high risk debt securities. The Fund also may invest in convertible securities, preferred stock, common stock and loan participations and assignments and commitments to purchase loan assignments.Under normal circumstances, the Fund invests at least 80% of its Assets in bonds, other debt securities, loan assignments and participations (Loans), commitments to purchase loan assignments (Unfunded Commitments) and preferred stocks that are rated below investment grade or unrated. For purposes of this policy, “Assets” means net assets plus the amount of borrowings for investment purposes. Up to 20% of the Fund’s total assets may be invested in other securities, including investment grade securities. The Fund’s average weighted maturity ordinarily will range between three and ten years, although the Fund may shorten its weighted average maturity to as little as two years if deemed appropriate for temporary defensive purposes. The Fund may have a longer or shorter average weighted maturity under certain market conditions. The Fund may invest no more than 30% of its net assets in Loans and Unfunded Commitments. Loans will typically consist of senior floating rate loans (Senior Loans), but may also include secured and unsecured loans, second lien loans or more junior (Junior Loans) and bridge loans. Loans may be issued by obligors in the U.S. or in foreign or emerging markets. The Fund may invest up to 100% of the Fund’s total assets in below investment grade or unrated securities. Such securities are also known as “junk bonds,” “high yield bonds” and “non-investment grade bonds.” Such securities may include so called “distressed debt”. Distressed debt includes securities of issuers experiencing financial or operating difficulties, securities where the issuer has defaulted in the payment of interest or principal or in the performance of its covenants or agreements, securities of issuers that may be involved in bankruptcy proceedings, reorganizations or financial restructurings or securities of issuers operating in troubled industries. All securities will be U.S. dollar-denominated although they may be issued by a foreign corporation, government or its agencies and instrumentalities. 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, options and swaps to hedge various investments, for risk management and/or to increase income or gain to the Fund. In particular, the Fund may invest in swaps structured as credit default swaps related to individual Loans or other securities or indexes of Loans or other securities to gain exposure to such Loans and other securities, to mitigate risk exposure or to manage cash flow needs. Although the Fund predominantly invests in debt securities and income producing securities, it may also invest in common stock from time to time. In addition, the Fund may acquire and hold such securities (or rights to acquire such securities) in connection with an amendment, waiver, conversion or exchange of fixed income securities, in connection with the bankruptcy or workout of distressed fixed income securities, or upon the exercise of a right or warrant obtained on account of a fixed income security. The adviser focuses on value in buying and selling securities for the Fund by looking at individual securities against the context of broader market factors. For each issuer, the adviser performs an in-depth analysis of the issuer, including business prospects, management, capital requirements, capital structure, enterprise value and security structure and covenants. In addition, the adviser monitors investments on an ongoing basis by staying abreast of positive and negative credit developments expediting the review of the Fund’s investments that are considered to be the most risky. Generally, the adviser will sell a security when, based on fundamental credit analysis and the considerations described above, the adviser believes the issuer’s credit quality will deteriorate materially or when the adviser believes that there is better relative value available in the market in securities of comparable quality. As part of its credit analysis, the adviser seeks to assess the impact of environmental, social and governance (ESG) factors on certain issuers in the universe in which the Fund may invest. The adviser’s assessment is based on an analysis of key opportunities and risks across industries to seek to identify financially material issues with respect to the Fund’s investments in issuers and ascertain key issues that merit engagement with issuers. These assessments may not be conclusive and securities of issuers that may be negatively impacted by such factors may be purchased and retained by the Fund while the Fund may divest or not invest in securities of issuers that may be positively impacted by such factors.

Summary of Selection Criteria for Rule 35d-1 Term in Fund Name [Text Block]

As part of its main investment strategy, the Fund may principally invest in U.S. treasury obligations, U.S. government agency securities, corporate bonds, asset-backed securities, mortgage-backed securities, mortgage-related securities, and structured instruments. These investments may be structured as collateralized mortgage obligations (agency and non-agency), commercial mortgage-backed securities and mortgage pass-through securities. U.S. government agency securities may be issued or guaranteed by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac). Under normal circumstances, the Fund invests at least 80% of its Assets in bonds. For purposes of this policy, “Assets” means net assets plus the amount of borrowings for investment purposes. The Fund seeks to maintain a duration of three years or less, although under certain market conditions such as in periods of significant volatility in interest rates and spreads, the Fund’s duration may be longer than three years. Duration is a measure of 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). Consistent with the Fund’s short duration strategy, the Fund’s effective average weighted maturity ordinarily will be three years or less taking into account expected amortization and prepayment of principal on certain investments. The Fund may have a longer or shorter average weighted maturity under certain market conditions and the Fund may shorten or lengthen its average weighted maturity if deemed appropriate for temporary defensive purposes. Because of the Fund’s holdings in asset-backed, mortgage-backed and similar securities, the Fund’s average weighted maturity is equivalent to the average weighted maturity of the cash flows in the securities held by the Fund given certain prepayment assumptions (also known as weighted average life). Securities purchased by the Fund will be rated investment grade (or the unrated equivalent) at the time of purchase. The "unrated equivalent" refers to securities that are unrated but deemed by the adviser to be of comparable quality. In addition, all securities will be U.S. dollar-denominated although they may be issued by a foreign corporation or a U.S. affiliate of a foreign corporation or a foreign government or its agencies and instrumentalities. The Fund may invest a significant portion or all of its assets in mortgage-related and mortgage-backed securities at the adviser’s discretion. The Fund expects to invest less than 5% of its assets in “sub-prime” mortgage-related securities at the time of purchase. The adviser buys and sells securities and investments for the Fund based on its view of individual securities and market sectors. 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, legal provisions and the structure of the transaction.

Summary of Selection Criteria for Rule 35d-1 Term in Fund Name [Text Block]

Under normal circumstances, the Fund invests at least 80% of its net Assets in municipal bonds, the income from which is exempt from federal income tax. This is a fundamental policy. For purposes of this policy, “Assets” means net assets, plus the amount of borrowings for investment purposes. Up to 25% of the Fund's Assets may be invested in municipal securities, the interest on which may be subject to the federal alternative minimum tax for individuals. The Fund invests in a portfolio of municipal bonds with an average weighted maturity of one to five 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. Municipal bonds are debt securities with maturities of 90 days or more at the time of issuance issued by states, territories and possessions of the United States, including the District of Columbia, and their respective authorities, political subdivisions, agencies and instrumentalities, the interest on which is exempt from federal income tax. The securities are issued to raise funds for various public and private purposes. Municipal bonds include private activity and industrial development bonds, tax anticipation notes and participations in pools of municipal securities. The Fund also invests in municipal mortgage-backed and asset-backed securities, as well as auction rate securities and restricted securities. The Fund may invest a significant portion or all of its assets in municipal mortgage-backed securities at the adviser’s discretion. The securities in which the Fund invests may have fixed rates of return or floating or variable rates. The Fund may invest more than 25% of its total assets in municipal housing authority obligations. Up to 20% of the Fund’s assets may be held in cash and cash equivalents. The Fund may invest up to 20% of its total assets in securities rated below investment grade. Such securities are known as “junk bonds,” “high yield bonds” and “non-investment grade bonds.” Junk bonds also include unrated securities that the adviser believes to be of comparable quality to debt securities that are rated below investment grade. 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, following the time of purchase, they would be deemed to be below investment grade. The "unrated equivalent" refers to securities that are unrated but deemed by the adviser to be of comparable quality. 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 may also invest in zero-coupon securities. Investment Process: The adviser buys and sells securities and investments for the Fund based on its view of individual securities and market 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. As part of its investment process, the adviser seeks to assess the impact of environmental, social and governance (ESG) factors on certain issuers in the universe in which the Fund may invest. The adviser’s assessment is based on an analysis of key opportunities and risks across industries to seek to identify financially material issues with respect to the Fund’s investments in municipal issues and ascertain key issues that merit engagement with municipal issuers.
