Supplement dated December 15, 2022

to the Summary Prospectuses, Prospectuses and Statements of Additional Information as dated above

At a meeting held on December 12, 2022, the Boards of Trustees agreed to consider in February 2023 the conversion of the following four mutual funds to newly created exchange-traded funds (the “ETFs”) (each, a “Conversion”):

Each new ETF will be managed in a substantially similar manner as the current mutual funds. If approved by the Boards of Trustees, it is currently proposed that the Conversions would occur on the following dates:

By converting these strategies to ETFs, J.P. Morgan Investment Management Inc. (“JPMIM”), the investment adviser for the mutual funds, believes shareholders in these mutual funds could benefit from reduced costs, including lower transfer agency costs for certain classes and no Rule 12b-1 or service fees. JPMIM is communicating the proposed plans prior to board approval in order to provide shareholders with ample notice of the proposed Conversions and allow them time to engage with JPMIM on the implications of the proposed transactions, including the need to have a brokerage account prior to the Conversion. It is possible that the Conversions will not be approved or will not occur for other reasons, in which case the changes described herein would not take effect.

Each Conversion generally would consist of (1) the transfer of the mutual fund’s assets, subject to its liabilities, to the corresponding shell ETF for shares of the ETF; and (2) the distribution of the ETF shares to the mutual fund shareholders in complete liquidation of the mutual fund. If approved by the Boards of Trustees, no shareholder approval will be required prior to each Conversion; existing shareholders of each mutual fund will receive prior to the Conversion a combined information statement/prospectus describing in detail both the Conversion and the surviving ETF, and summarizing the Board’s considerations in approving the Conversion.

When the Conversions are considered, each Board of Trustees, including the Trustees not deemed to be “interested persons” of the mutual funds pursuant to Section 2(a)(19) of the Investment Company Act of 1940, as amended, will need to determine whether the Conversion is in the best interests of the target mutual fund and that the Conversion would not dilute the interests of the mutual fund’s shareholders.

The new ETFs have not commenced investment operations, and it is anticipated that each will not have shareholders prior to the Conversion.

It is anticipated that each Conversion will qualify as a tax-free reorganization for federal income tax purposes and that shareholders will not recognize any gain or loss in connection with the Conversion, except to the extent that they receive cash in connection with the Conversion.

If (and only if) the Conversions are approved, the following changes will take effect on March 1, 2023 (the “Effective Date”):

Further information regarding these changes is included in the table below. As noted above, each of these changes will be implemented only if the Boards of Trustees approve the Conversions.

*         *         *         *         *

If the Conversions are approved by the Board, an information statement/prospectus that will be included in a registration statement on Form N-14 will be filed with the Securities and Exchange Commission (the “SEC”). After the registration statement is filed with the SEC, it may be amended or withdrawn and the information statement/prospectus will not be distributed to shareholders unless and until the registration statement is declared effective by the SEC. Investors are urged to read the materials and any other relevant documents when they become available because they will contain important information about the Conversions. After they are filed, free copies of the materials will be available on the SEC’s web site at www.sec.gov. These materials also will be available at www.jpmorganfunds.com and a paper copy can be obtained at no charge by calling 1-800-480-4111.

J.P. Morgan Asset Management Proposes Conversion

of Select Mutual Funds to ETFs

NEW YORK, December 15, 2022: J.P. Morgan Asset Management has announced plans to convert select U.S. mutual funds to ETFs in 2023, following the successful conversion of four mutual funds to ETFs earlier in 2022.

The proposed conversions, which are subject to fund board approval, are expected to provide benefits for investors of the mutual funds, including lower net expenses (for at least three years from the date of each conversion). The additional trading flexibility, increased portfolio holdings transparency and potential for enhanced tax efficiency that come with ETFs carry significant value to many investors, and J.P. Morgan believes these particular strategies are well suited for the ETF structure. The combined assets of the funds proposed for conversion are approximately $2 billion (as of 11/30/2022).

The board expects to consider these conversions in February 2023. If approved, the following mutual funds would be converted to actively managed transparent ETFs with substantially the same investment strategies as the current mutual funds:

By converting these four mutual funds to actively managed ETFs, J.P. Morgan would provide investors with active investment options in spaces that traditionally have seen mostly passive ETF solutions. If the board does not approve the conversions for any reason, then they will not occur.

Subject line: Proposed mutual fund conversions to ETFs

Dear [insert name here]:

Following the successful conversion of four mutual funds to ETFs earlier this year, J.P. Morgan Asset Management’s Funds board of directors recently agreed to consider the conversion of additional mutual funds into ETFs. Pending board approval, we plan to convert the following funds into actively-managed, transparent ETFs – while maintaining a substantially similar investment strategy – in July 2023.

While the conversions are subject to Board approval, we are communicating our proposed plans in advance so that, if approved and implemented, you have ample time to consider and discuss with us the potential implications of this important effort.

If approved and implemented, the conversion of these four funds to actively-managed ETFs can provide investors with active investment options in markets traditionally available to ETF investors mostly through passive solutions. In addition, shareholders may potentially benefit from greater tax-efficiency, intra-day trading, increased liquidity and reduced fees.

For additional information related to these changes, please refer to the latest supplement in each Fund’s prospectus by clicking on the Fund name above.

If you’d like to discuss these changes further, please don’t hesitate to contact me or simply click here to schedule a meeting with me:
