6. The first bullet under "Rights of Accumulation ("ROA")" under "Edward D. Jones & Co., L.P. ("Edward Jones")" in the "Appendix" section of the statutory portion of the prospectus is amended to read as follows:

Rights of Accumulation ("ROA")

· The applicable sales charge on a purchase of Class A shares is determined by taking into account all share classes (except certain money market funds and any assets held in group retirement plans) of American Funds and CollegeAmerica 529 Plan held by the shareholder or in an account grouped by Edward Jones with other accounts for the purpose of providing certain pricing considerations ("pricing groups"). If grouping assets as a shareholder, this includes all share classes held on the Edward Jones platform and/or held on another platform. The inclusion of eligible fund family assets in the ROA calculation is dependent on the shareholder notifying Edward Jones of such assets at the time of calculation. Money market funds are included only if such shares were sold with a sales charge at the time of purchase or acquired in exchange for shares purchased with a sales charge

7. The information under "Merrill Lynch, Pierce, Fenner & Smith ("Merrill Lynch")" in the "Appendix" section of the statutory portion of the prospectus is amended to read as follows:

Merrill Lynch, Pierce, Fenner & Smith ("Merrill Lynch")

Purchases or sales of front-end (for example, Class A) or level-load (for example, Class C) mutual fund shares through a Merrill Lynch 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 Lynch at the time of purchase or sale of any relationship or other facts that qualify the transaction for a waiver or discount. A Merrill Lynch representative may ask for reasonable documentation of such facts and Merrill Lynch may condition the granting of a waiver or discount on the timely receipt of such documentation.

Additional information on waivers, discounts, and share class exchanges is available in the Merrill Lynch Sales Load Waiver and Discounts Supplement (the "Merrill Lynch SLWD Supplement") and in the Mutual Fund Investing at Merrill Lynch 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.

Except as provided below, Class A shares are not currently available to new plans described in this waiver. Plans that invested in Class A shares of any of the funds without any sales charge before April 1, 2004, and that continue to meet the eligibility requirements in effect as of that date for purchasing Class A shares at net asset value, may continue to purchase Class A shares without any initial or contingent deferred sales charge. For purposes of this provision, employer-sponsored retirement plans do not include SEP IRAs, SIMPLE IRAs, SARSEPs or Keogh plans
· Shares purchased through a Merrill Lynch investment advisory program. Class A shares are not currently available in the programs described in this waiver
· Brokerage class shares exchanged from advisory class shares due to the holdings moving from a Merrill Lynch investment advisory program to a Merrill Lynch brokerage account
· Shares purchased through the Merrill Lynch Edge Self-Directed platform. Class A shares are not currently available in the programs described in this waiver

· 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 Lynch's account maintenance fees are not eligible for Rights of Reinstatement

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 Lynch permits to be assessed to a front-end load purchase, as described in the Merrill Lynch SLWD Supplement
· Rights of Accumulation (ROA), as described in the Merrill Lynch SLWD Supplement, which entitle clients to breakpoint discounts based on the aggregated holdings of mutual fund family assets held in accounts in their Merrill Lynch Household

On or about May 1, 2026, assets not held at Merrill Lynch will no longer be included in the ROA calculation. For more detail on the timing and calculation, please refer to the Merrill Lynch 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 Lynch, in accounts within your Merrill Lynch Household, as further described in the Merrill Lynch SLWD Supplement

On or about May 1, 2026, Merrill Lynch will no longer accept new LOIs. For more detail on the timing, please refer to the Merrill Lynch SLWD Supplement.

CollegeAmerica accounts

If clients establish or hold their CollegeAmerica 529 Plan (Plan) accounts on the Merrill Lynch omnibus platform, the features and policies related to share class sales charges (including contingent deferred sales charges (CDSC), if any), share class sales charge waivers or discounts, letters of intent (LOI) and reinstatement privileges, and Class 529-C share conversion period will be different than referenced in this document and will be governed by the Merrill Lynch 529 Account Unit Class Disclosure and Terms and Conditions (T&Cs) provided to clients by Merrill Lynch prior to establishing their Plan account.

Except as described in this Merrill Lynch specific section of this document and the T&Cs, Merrill Lynch does not offer any initial sales charge discounts, CDSC waivers, LOI or reinstatement privileges in the 529 plans offered on the Merrill Lynch omnibus platform (the "529 Discounts, Waivers and Privileges"). To receive the 529 Discounts, Waivers, and Privileges not offered by Merrill Lynch, clients will have to invest in the Plan directly or through another intermediary.

Before investing in the Plan through Merrill Lynch, clients should consider the potential benefits and importance to them of such 529 Discounts, Waivers, and Privileges.

For additional information on the Discounts, Waivers, and Privileges and Merrill Lynch's policies, clients are encouraged to contact their financial advisor or refer to the T&C.

If clients establish or hold their Plan accounts on the Merrill Lynch omnibus platform, then the share class (described as unit class in the T&Cs) their account will purchase will generally be based on their eligible assets or meeting other eligibility criteria as set forth in the T&Cs. The Plan offered by Merrill Lynch on its omnibus platform will have two share classes - Class 529-A share and Class 529-C share-each with its own fee and expense structure. Each account will purchase a specific share class when an initial or subsequent contribution is credited to the account. The share class will be automatically determined at the time of the contribution based on the participant's eligible assets and/or meeting other eligibility criteria. Clients will not be able to select the share class. Among other things, Class 529-C shares will be automatically converted to Class 529-A shares (not subject to an initial sales charge) after four years from their respective dates of purchase. If the Plan permits Class 529-C shares' conversion sooner than four years, such earlier conversion date will automatically apply.

For additional information, clients are encouraged to contact their financial advisor or refer to the T&Cs.
