Under FDP, most agencies do not require carry-overs to be approved. However, award documents may indicate if unobligated balances are restricted or require agency approval to carry over. Unrestricted balances at the end of a budget year will be carried forward to the following budget year, except for the final budgeted year of the award. Unexpended funds remaining at the award termination date are relinquished to the agency.
