What is a problem disbursement in Foreign Military Sales, and how is it resolved?
A problem disbursement is a payment that the accounting office cannot match to the obligation or receivable it should liquidate: an unmatched disbursement, or a where payments exceed the obligation recorded. The fund holder and the accounting office research it, then resolve it against its obligation source in a set order, with the Comptroller deciding the cases that cannot be matched. Every problem disbursement must be resolved before the case can close.
What is a problem disbursement in Foreign Military Sales, and how is it resolved?
Reconciliation starts when a case is implemented, not when it is ready to close: logistics and financial records are reconciled as material is delivered and services are performed, and each annual case review checks them against the LOA. A case becomes Supply/Services Complete (SSC) when everything is delivered and performed; reconciliation for closure then runs until nothing is left unmatched, and only then can the case be certified and submitted for closure. What follows is shown in How a Foreign Military Sales case closes, on the Reconciliation & Closure stage.
