Interest and other financial costs. Interest on borrowing (such as mortgages or other loans, however represented), bond discounts, points, costs of financing and refinancing operations, mortgage insurance, credit reports, and legal and professional fees paid in connection therewith are unallowable, except when authorized by Federal legislation.
Payment of interest penalties for late payment of bills to contractors is prohibited by the Prompt Payment Act (P.L. 97-177). The act specifies:
"(A) in no case shall an obligation to pay such interest penalties be construed to be an obligation of the United States," and
"(B) Any payment of such interest penalties shall not be made from funds provided to the grant recipient by a Federal agency, nor shall any non-Federal funds expended for such interest penalties be counted toward any matching requirement applicable to that grant."
