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 6/30/14 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

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 24% of the average value of its portfolio.

What are the Fund’s main investment strategies?

The Fund mainly invests in mortgage-backed securities, asset-backed securities, mortgage-related securities, adjustable rate mortgages, money market instruments, and structured investments. These investments may be structured as collateralized mortgage obligations (agency and non-agency), stripped mortgage-backed securities, commercial mortgage-backed securities, and mortgage pass-through securities. These securities may be structured such that payments consist of interest-only (IO), principal-only (PO) or principal and interest. Under normal circumstances, the Fund will invest 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 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” 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 Fund invests in fixed and floating rate debt securities representing an interest in or secured by residential mortgage loans. These securities often are issued or guaranteed by the U.S. government, its agencies or instrumentalities such as the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac). However, the Fund may also purchase mortgage-backed securities and asset-backed securities that are issued by nongovernmental entities. Such securities may or may not have private insurer guarantees of timely payments.

Securities purchased by the Fund will be rated investment grade (or the unrated equivalent) at the time of purchase. 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 may invest up to 25% of its assets in “sub-prime” mortgage-related securities at the time of purchase.

The Fund has flexibility to invest in derivatives and may use such instruments to manage duration, sector and yield curve exposure, credit and spread volatility and to respond to volatile market conditions. Derivatives, which are instruments which 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. The Fund may use futures contracts, options, and swaps in connection with its principal strategies in order to hedge various investments, for risk management purposes and/or to increase income or gain to the Fund.

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.

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.

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 drops. 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 a counterparty will fail to make payments when due or default completely. If an issuer’s financial condition worsens, the credit quality of the issuer may deteriorate making it difficult for the Fund to sell such investments.

Government Securities Risk. The Fund invests in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as 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 would 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 IOs and 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.

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, 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.

Derivatives Risk. Derivatives, including futures contracts, options and 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.

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.

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

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 over 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 Barclays 1–3 Year U.S. Government/Credit Bond Index and Lipper Short-Intermediate Investment Grade Debt Funds Index. The Lipper index is based on the total returns of certain mutual funds within the designated category as determined by Lipper. Unlike the other index, the Lipper index includes the 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 perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

The Fund’s year-to-date total return through 3/31/13 was 0.92%.

After-tax returns are shown for only the Select Class Shares and after-tax returns for the other classes will vary. 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.

In general, you may purchase or redeem shares on any business day

Tax Information

The Fund intends to make distributions that may be taxed as ordinary income or capital gains, except when your investment is in an IRA, 401(k) plan or other tax-advantaged investment plan in which case you may be subject to federal income tax upon withdrawal from the tax-advantaged investment plan.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and its related companies may pay the financial intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or financial intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.
