[1] American Beacon Advisors, Inc. (the “Manager”) has contractually agreed to waive fees and/or reimburse expenses of the Fund’s A Class, C Class, Y Class, R5 Class, and Investor Class shares, as applicable, through April 30, 2026, to the extent that Total Annual Fund Operating Expenses exceed 1.85% for the A Class, 2.62% for the C Class, 1.65% for the Y Class, 1.53% for the R5 Class, and 1.94% for the Investor Class (excluding taxes, interest, brokerage commissions, acquired fund fees and expenses, securities lending fees, expenses associated with securities sold short, litigation, and other extraordinary expenses). The contractual expense reimbursement can be changed or terminated only in the discretion and with the approval of a majority of the Fund’s Board of Trustees (“Board”). The Manager will itself waive fees and/or reimburse expenses of the Fund to maintain the contractual expense ratio caps for each applicable class of shares or make arrangements with other service providers to do so. The Manager can be reimbursed by the Fund for any contractual fee waivers or expense reimbursements if reimbursement to the Manager (a) occurs within three years from the date of the Manager’s waiver/reimbursement and (b) does not cause the Total Annual Fund Operating Expenses of a class to exceed the lesser of the contractual percentage limit in effect at the time of the waiver/reimbursement or the time of the recoupment.
