Authority provided in an appropriations act to obligate and disburse during a Fiscal Year (FY) before that in which the related end item is procured. The funds are added to the Budget Authority (BA) for the FY and deducted from the BA of the succeeding FY. AP is used in major acquisition programs to obtain components whose Long Lead Time (LLT) requires early purchase in order to reduce the overall Procurement Lead Time (PLT) of the major end item. AP of long-lead components is an exception to the DoD “full funding” policy and must be part of the President's Budget (PB) request.
