Program Income means gross in- come earned by the recipient that is di- rectly generated by a supported activ- ity or earned as a result of the award (see exclusions in § 215.24(e) and (h)). Program income includes, but is not limited to, income from fees for serv- ices performed, the use or rental of real or personal property acquired under federally-funded projects, the sale of commodities or items fabricated under an award, license fees and royalties on patents and copyrights, and interest on loans made with award funds. Interest earned on advances of Federal funds is not program income. Except as other- wise provided in Federal awarding agency regulations or the terms and conditions of the award, program in- come does not include the receipt of principal on loans, rebates, credits, dis- counts, etc., or interest earned on any of them.
