Amounts appropriated in any fiscal year to carry out the provisions of sections
450ss to
450ss–7 may only be expended on a matching basis in a ratio of at least one non-Federal dollar to every Federal dollar. For the purposes of this provision, each non-Federal dollar donated to the Foundation for the creation, maintenance, operation, or endowment of the Memorial shall satisfy the matching dollar requirement without regard to the fiscal year in which such donation is made.
