[1]	Other Expenses and Acquired Fund Fees and Expenses are based on estimated expenses for the current fiscal year.
[2]	The Fund invests in a wholly owned subsidiary organized under Delaware law (the "Delaware Subsidiary"). The Delaware Subsidiary's financial statements are consolidated with those of the Fund. The Delaware Subsidiary is classified for federal income tax purposes as a taxable regular corporation or so-called Subchapter "C" corporation. As a "C" corporation, the Delaware Subsidiary accrues deferred tax liability for its future tax liability associated with any gains that the Delaware Subsidiary may recognize on future sales of its sole investment, which is shares of the Bitcoin Investment Trust, a Delaware statutory trust that invests in bitcoin. The deferred tax expense represents an estimate of the Delaware Subsidiary's potential tax expense if it were to recognize the unrealized gains in its portfolio. An estimate of deferred tax expense is dependent upon the Delaware Subsidiary's net investment income and realized and unrealized gains on investments. Such expenses may vary greatly from year to year and from day to day depending on the performance of the Bitcoin Investment Trust. Therefore, any estimate of the Delaware Subsidiary's deferred tax expense cannot be reliably predicted from year to year. As described in Footnote 4 below, American Beacon Advisors, Inc. (the "Manager") has contractually agreed to reimburse the Fund for the amount of any tax liability incurred by the Delaware Subsidiary in connection with the sale of shares of the Bitcoin Investment Trust currently held by the Delaware Subsidiary. Therefore, the Fund's accrued deferred tax liability, if any, does not impact the Fund's net asset value per share.
[3]	American Beacon Advisors, Inc. (the "Manager") has contractually agreed to waive fees and/or reimburse expenses of the Fund's Y Class, Institutional Class and Investor Class shares through December 31, 2018 to the extent that Total Annual Fund Operating Expenses exceed 1.09% for the Y Class, 0.99% for the Institutional Class and 1.37% 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. 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 after the Manager's own waiver or 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.
[4]	The Manager has contractually agreed to reimburse the Fund for the amount of any tax liability incurred by the Delaware Subsidiary in connection with the sale of the Bitcoin Investment Trust shares currently held by the Delaware Subsidiary for so long as the Delaware Subsidiary continues to hold this investment. The contractual agreement can be changed or terminated only in the discretion and with the approval of a majority of the Fund's Board of Trustees.

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same, except that the Example reflects the fee waiver/expense reimbursement arrangement for each share class through December 31, 2018, and the tax liability reimbursement arrangement. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:
