**TO THE PROSPECTUS DATED MAY 9, 2025**

Effective November 19, 2025, the following disclosure is added to the "Appendix A—Financial Intermediary—Specific Sales Charge Waivers and Discounts" section of the Prospectus:

The following information is provided by J.P. Morgan Securities LLC

**<u>J.P. MORGAN SECURITIES LLC</u>**

If you purchase or hold fund shares through an applicable J.P. Morgan Securities LLC brokerage account, you will be eligible for the following sales charge waivers (front-end sales charge waivers and contingent deferred sales charge ("CDSC"), or back-end sales charge, waivers), share class conversion policy and discounts, which may differ from those disclosed elsewhere in this fund's prospectus or Statement of Additional Information ("SAI").

**Front-end sales charge waivers on Class A shares available at J.P. Morgan Securities LLC** 

&nbsp;&nbsp;&nbsp;&nbsp;· Shares exchanged from Class C (i.e., level-load) shares that are no longer
subject to a CDSC and are exchanged into Class A shares of the same fund pursuant to J.P. Morgan Securities LLC's share class exchange
policy.

&nbsp;&nbsp;&nbsp;&nbsp;· Qualified employer-sponsored defined contribution and defined benefit retirement
plans, nonqualified deferred compensation plans, other employee benefit plans and trusts used to fund those plans. For purposes
of this provision, such plans do not include SEP IRAs, SIMPLE IRAs, SAR-SEPs or 501(c)(3) accounts.

&nbsp;&nbsp;&nbsp;&nbsp;· Shares of funds purchased through J.P. Morgan Securities LLC Self-Directed
Investing accounts.

&nbsp;&nbsp;&nbsp;&nbsp;· Shares purchased through rights of reinstatement.

&nbsp;&nbsp;&nbsp;&nbsp;· Shares purchased through reinvestment of capital gains distributions and
dividend reinvestment when purchasing shares of the same fund (but not any other fund within the fund family).

&nbsp;&nbsp;&nbsp;&nbsp;· Shares purchased by employees and registered representatives of J.P. Morgan
Securities LLC or its affiliates and their spouse or financial dependent as defined by J.P. Morgan Securities LLC.

**Class C to Class A share conversion**

&nbsp;&nbsp;&nbsp;&nbsp;· A shareholder in the fund's Class C shares will have their shares converted
by J.P. Morgan Securities LLC to Class A shares (or the appropriate share class) of the same fund if the shares are no longer subject
to a CDSC and the conversion is consistent with J.P. Morgan Securities LLC's policies and procedures.

**CDSC waivers on Class A and C shares available at J.P. Morgan Securities LLC** 

&nbsp;&nbsp;&nbsp;&nbsp;· Shares sold upon the death or disability of the shareholder.

&nbsp;&nbsp;&nbsp;&nbsp;· Shares sold as part of a systematic withdrawal plan as described in the fund's
prospectus.

&nbsp;&nbsp;&nbsp;&nbsp;· Shares purchased in connection with a return of excess contributions from
an IRA account.

&nbsp;&nbsp;&nbsp;&nbsp;· Shares sold as part of a required minimum distribution for IRA and retirement
accounts pursuant to the Internal Revenue Code.

&nbsp;&nbsp;&nbsp;&nbsp;· Shares acquired through a right of reinstatement.

**Front-end load discounts available at J.P. Morgan Securities LLC: breakpoints, rights of accumulation & letters of intent**

&nbsp;&nbsp;&nbsp;&nbsp;· Breakpoints as described in the prospectus.

&nbsp;&nbsp;&nbsp;&nbsp;· Rights of Accumulation ("ROA") which entitle shareholders to
breakpoint discounts as described in the fund's prospectus will be automatically calculated based on the aggregated holding of fund
family assets held by accounts within the purchaser's household at J.P. Morgan Securities LLC. Eligible fund family assets not held
at J.P. Morgan Securities LLC (including 529 program holdings, where applicable) may be included in the ROA calculation only if the shareholder
notifies their financial advisor about such assets.

&nbsp;&nbsp;&nbsp;&nbsp;· Letters of Intent ("LOI") which allow for breakpoint discounts
based on anticipated purchases within a fund family, through J.P. Morgan Securities LLC, over a 13-month period of time (if applicable).
