¹American Beacon Advisors has contractually agreed to reduce and/or reimburse the A Class, C Class, Y Class and Investor Class of the Fund for distribution fees and other expenses, as applicable, through February 28, 2013.

Important Information: There is no guarantee that the investment objectives will be met. Indices are unmanaged and one cannot invest directly in an index.

For any Class of the Fund that began operating within the ten-year/since inception period shown, the performance shown prior to the inception date of the Class is that of a class (or series of classes) previously in operation. The combined returns have not been adjusted for any difference between the fees and expenses of the Class and the historical fees and expenses of the included previous class (or classes). If the previous class(es) had lower expenses, the resulting performance would be better than the Class would have realized during the same period. If the previous class(es) had higher expenses, the resulting performance would be lower than the Class would have realized during the same period. For the Investor Class, a portion of the fees charged to the Fund has been waived. Performance prior to waiving fees was lower than the actual returns shown. Class C shares may be subject to a contingent deferred sales charge of up to 1% on certain redemptions made within 12 months of purchase. Performance presented at NAV, which does not include these sales charges, would be lower if these charges were reflected. Specific information about any Fund may be found at americanbeaconfunds.com or in the prospectus.
