| <b>JPMorgan Inflation Managed Bond Fund<br/>Class/Ticker: R5/JIMRX; R6/JIMMX</b> | |||||||||||||||||||||||||||||||||||||||||||||
| <b>What is the goal of the Fund? </b> | |||||||||||||||||||||||||||||||||||||||||||||
| The Fund seeks to maximize inflation protected total return. | |||||||||||||||||||||||||||||||||||||||||||||
| <b>Fees and Expenses of the Fund </b> | |||||||||||||||||||||||||||||||||||||||||||||
| The following table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. | |||||||||||||||||||||||||||||||||||||||||||||
| <b>ANNUAL FUND OPERATING EXPENSES<br/>(Expenses that you pay each year as a percentage of the value<br/>of your investment)</b> | |||||||||||||||||||||||||||||||||||||||||||||
| |||||||||||||||||||||||||||||||||||||||||||||
| <b>Example </b> | |||||||||||||||||||||||||||||||||||||||||||||
| 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 9/30/19 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower. | |||||||||||||||||||||||||||||||||||||||||||||

| <b>Portfolio Turnover </b> | |||||||||||||||||||||||||||||||||||||||||||||
| 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 68% of the average value of its portfolio. | |||||||||||||||||||||||||||||||||||||||||||||
| <b>What are the Fund’s main investment strategies? </b> | |||||||||||||||||||||||||||||||||||||||||||||
| The Fund is designed to protect the total return generated by its core fixed income holdings from inflation risk. As used in the Fund’s goal, “total return” includes income and capital appreciation. The Fund seeks to hedge this risk by using swaps that are based on the Non-Seasonally Adjusted Consumer Price Index for all Urban Consumers (CPI-U) in combination with its core portfolio of fixed income securities. This strategy is intended to create the equivalent of a portfolio of inflation-protected fixed income securities. Secondarily, the Fund may purchase other investments including actual inflation-protected securities such as Treasury Inflation Protected Securities (TIPS). “Inflation Managed” in the Fund’s name does not refer to a type of security in which the Fund invests, but rather describes the Fund’s overall strategy of creating a portfolio of inflation-protected securities. 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. As part of its main investment strategy, the Fund may principally invest in corporate bonds, U.S. government and agency debt securities, asset-backed securities, and mortgage-related and mortgage-backed securities. 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, and mortgage pass-through securities. Additional information about these types of investments may be found in “Investment Practices” in the Fund’s prospectus. The Fund may invest up to 10% of the Fund’s total assets in securities that, at the time of purchase, are rated below investment grade (also known as junk bonds or high yield securities) by Moody’s Investor Service, Inc. (Moody’s), Standard & Poor’s Corporation (S&P), Fitch Rating (Fitch) or the equivalent by another national rating organization, or securities that are unrated but are 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, 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 no more than 10% of its assets in “sub-prime” mortgage-related securities at the time of purchase. The Fund uses derivatives as a principal strategy. Derivatives are instruments that have a value based on another instrument, exchange rate or index. The Fund uses CPI-U swaps for inflation hedging purposes. In addition to CPI-U swaps, the Fund has flexibility to use swaps (including credit default swaps) and futures for hedging purposes, to increase income and gain to the Fund, and as part of its risk management process by establishing or adjusting exposure to particular securities or markets and/or to manage cash flows. The Fund may use swaps structured as credit default swaps to gain or hedge exposure to high yield securities or indexes of high yield securities. 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. | |||||||||||||||||||||||||||||||||||||||||||||
| <b>The Fund’s Main Investment Risks </b> | |||||||||||||||||||||||||||||||||||||||||||||
| 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 securities in general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for 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 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 that the Federal Reserve has been raising interest rates, the Fund may face a heightened level of interest rate risk. 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. Strategy Risk. The Fund’s investment strategies may not work to generate inflation-protected return. There is no guarantee that the use of derivatives and debt securities will mimic a portfolio of inflation-protected bonds. Derivatives Risk. The Fund may have significant exposure to derivatives. Derivatives, including swaps, credit default swaps on securities and indices of securities and futures, 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. 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 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 security 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 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. High Yield Securities Risk. The Fund invests in instruments including junk bonds and instruments that may be issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments are considered to be speculative and are 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, and lack of publicly available information. Because some instruments may have a more limited secondary market, liquidity and valuation risk is more pronounced for the Fund than for funds that invest primarily in other types of fixed income instruments or equity securities. Inflation-Protected Securities 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-protected securities such as TIPS are 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 actual 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. 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. 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 payments 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. 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. Foreign Issuer Risks. 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 foreign countries. 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. 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. 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. | |||||||||||||||||||||||||||||||||||||||||||||
| <b>The Fund’s Past Performance </b> | |||||||||||||||||||||||||||||||||||||||||||||
| 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 seven 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 Bloomberg Barclays 1-10 Year U.S. TIPS Index, the Bloomberg Barclays U.S. Intermediate Aggregate Index, the Inflation Managed Bond Composite Benchmark (a composite benchmark determined by adding the Bloomberg Barclays Intermediate Government/ Credit Index and 80% of the Bloomberg Barclays Inflation Swap 5 Year Zero Coupon Index) and the Lipper Inflation-Protected Bond 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 the Class R6 Shares is based on the performance of the Class R5 Shares prior to the inception of Class R6 Shares. The actual return of Class R6 Shares would have been different than those shown because Class R6 Shares have different expenses than Class R5 Shares. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.
