 Such proportion is solely decided by the federal government, but usually the recipient decides how that contribution is provided and to which expenses, so long as the contribution is verifiable, generally does not originate from another federal program, and is considered in the operating budget.The expenses must be necessary and reasonable, allowed under cost principles (see B section above), and not used for another federal program.Matching may be in the form of contributing the recipient's own funds or money to suffrage program allowable costs (e.g., paying program utility bills, paying part of program personnel payroll, etc.)
