 Program income is sometimes directly generated by the federally funded program . This type of income includes , but is not limited to , income from fees for services performed , the use or rental of property acquired with program funds , the sale of items fabricated under the program , and payments of principal and interest on loans made by the recipient to others with program funds . However , it generally does not include interest on program funds ( which is covered under “ Cash Management ” , see above ) ; nor does it cover rebates , credits , discounts , and refunds ( covered under “ Allowable Costs / Cost Principles ” ) ; nor proceeds from the sale of equipment or real property ( covered under “ Equipment and Real Property Management ” ) . The uses or treatment of program income are either deducted by the federal agency from the current program budget ( e.g. , the program income substitutes part of the original budget ) , added to the current program budget , or used to meet matching requirements .
