The time limit is available for new obligations for three (3) fiscal years. This appropriation is controlled at the command level on a program-year and line-item basis. Under the program-year concept, new procurement programs should be obligated during the first year of availability to the extent possible. A program year consists of all programs budgeted and approved for funding in a specific budget year. Each procurement action is charged to the program year under which it was budgeted. Subsequently, within scope program cost changes are funded from the program-year account under which the basic transaction occurred.
Types of Costs
Investment costs and intrinsic items of expense when included in the production item/modified item.
Production quantities, when specified, must match Conference Appropriations Committee tables unless Congressional language allows for the procurement of additional quantities or approval is obtained to buy-to-budget. The majority of these programs do not have quantities specified and may accelerate procurement buys so long as inventory objectives are not exceeded and sponsor approval is obtained.
