Some sponsored programs generate income (e.g., from registration fees for conferences, the sale of materials developed with sponsor funds, etc.). Sponsors, especially federal agencies, may have regulations and policies about how program-generated income should be accounted for and spent.
If the products or resources provided by the grant/contract are or may be involved in the generation of income, the PI/PD should contact the Accounting Office to identify procedures for the accounting for and spending of sponsored program-generated funds.
