The information in this Supplement amends certain information contained in the currently effective Prospectus for the Funds, dated November 1, 2025, as supplemented on January 27, 2026, and should be read in conjunction with such Prospectus.
Effective May 1, 2026, the following information replaces the Merrill Lynch disclosure under the section of the Funds’ Prospectus entitled “APPENDIX A: INTERMEDIARY-SPECIFIC SALES CHARGE REDUCTIONS AND WAIVERS”:
MERRILL LYNCH
Purchases or sales of front-end (i.e. Class A) or level-load (i.e., Class C) mutual fund shares through a Merrill platform or account will be eligible only for the following sales load waivers (front-end, contingent deferred, or back-end waivers) and discounts, which differ from those disclosed elsewhere in this Fund’s prospectus. Purchasers will have to buy mutual fund shares directly from the mutual fund company or through another intermediary to be eligible for waivers or discounts not listed below.
It is the client’s responsibility to notify Merrill at the time of purchase or sale of any relationship or other facts that qualify the transaction for a waiver or discount. A Merrill representative may ask for reasonable documentation of such facts and Merrill may condition the granting of a waiver or discount on the timely receipt of such documentation.
Additional information on waivers and discounts is available in the Merrill Sales Load Waiver and Discounts Supplement (the “Merrill SLWD Supplement") and in the Mutual Fund Investing at Merrill pamphlet at ml.com/funds. Clients are encouraged to review these documents and speak with their financial advisor to determine whether a transaction is eligible for a waiver or discount.
Front-end Load Waivers on Class A Shares available at Merrill Lynch
| · | Shares of mutual funds available for purchase by employer-sponsored retirement, deferred compensation, and employee benefit plans (including health savings accounts) and trusts used to fund those plans provided the shares are not held in a commission-based brokerage account and shares are held for the benefit of the plan. For purposes of this provision, employer-sponsored retirement plans do not include SEP IRAs, Simple IRAs, SAR-SEPs or Keogh plans |
| · | Shares purchased through a Merrill investment advisory program |
| · | Brokerage class shares exchanged from advisory class shares due to the holdings moving from a Merrill investment advisory program to a Merrill brokerage account |
| · | Shares purchased through the Merrill Edge Self-Directed platform |
| · | Shares purchased through the systematic reinvestment of capital gains distributions and dividend reinvestment when purchasing shares of the same mutual fund in the same account |
| · | Shares exchanged from level-load shares to front-end load shares of the same mutual fund in accordance with the description in the Merrill SLWD Supplement |
| · | Shares purchased by eligible employees of Merrill or its affiliates and their family members who purchase shares in accounts within the employee’s Merrill Household (as defined in the Merrill SLWD Supplement) |
| · | Shares purchased by eligible persons associated with the fund as defined in this prospectus (e.g. the fund’s officers or trustees) |
| · | Shares purchased from the proceeds of a mutual fund redemption in front-end load shares provided (1) the repurchase is in a mutual fund within the same fund family; (2) the repurchase occurs within 90 calendar days from the redemption trade date, and (3) the redemption and purchase occur in the same account (known as Rights of Reinstatement). Automated transactions (i.e. systematic purchases and withdrawals) and purchases made after shares are automatically sold to pay Merrill’s account maintenance fees are not eligible for Rights of Reinstatement |

Class A Shares Front-end load Discounts Available at Merrill Lynch: Breakpoints, Rights of Accumulation & Letters of Intent
| · | Breakpoint discounts, as described in this prospectus, where the sales load is at or below the maximum sales load that Merrill permits to be assessed to a front-end load purchase, as described in the Merrill SLWD Supplement |
| · | Rights of Accumulation (ROA), as described in the Merrill SLWD Supplement, which entitles clients to breakpoint discounts based on the aggregated holdings of mutual fund family assets held in accounts in their Merrill Household |
On or about May 1, 2026, assets not held at Merrill will no longer be included in the ROA calculation. For more detail on the timing and calculation, please refer to the Merrill SLWD Supplement.
| · | Letters of Intent (LOI), which allow for breakpoint discounts on eligible new purchases based on anticipated future eligible purchases within a fund family at Merrill, in accounts within your Merrill Household, as further described in the Merrill SLWD Supplement. |
On or about May 1, 2026, Merrill will no longer accept new LOIs. For more detail on the timing, please refer to the Merrill SLWD Supplement.
