When the Appropriation act has passed and the Army begins to use budgetary resources, the funding progresses through various statuses.
These statuses are tracked through specific budgetary accounts.
The first budgetary status is Appropriation from Congress.
Apportionment further limits spending by quarters or by Annual Funded Programming (AFP)
Budget Authority cannot be allotted until apportionment by OMB
The third status is Allocation. After the transfer from Apportionment to Allocation, funds are distributed to the Command (Level 1 to Level 2 Funds Centers).
