Hello I'm hoping to gain some understanding in the contract administration process when it comes to submitting a final invoice to the government on cost reimbursible contracts when final indirect cost rates have been settled.
In my scenario, I have cost reimbursible (CPFF) contracts that are physically complete. Final indirect cost rate for a particular fiscal year have been settled between the contractor and government. Per FAR 52.216-7(d)(5) the contractor has 120 days to submit a completion invoice to reflect settled amounts/rates. Unless final rates are equal to provisional billing rates, the rates will be adjusted and actual contract cost will more or less than prior to the final indirect rate settlement. If actual contract cost after rate adjustment is less than what the contractor has nvoiced, the contractor has "overbilled". If the actual contract cost after rate adjustment is more than what the contractor has invoiced, the contractor has "underbilled". Schedule I in the incurred cost proposal calls out these amounts.
My question is how these overbillings and underbillings are handled in the final invoice in situations where there is no additional funding on the contract. If the contractor overbilled, I expect the government wants the amount paid back to them. If the contractor underbilled, and with no funding, I'm not sure what happens.
Also what happens in the same scenario if the final indirect rates are settled for a fiscal year greater than 6 years ago?
Thanks.
