What is a Foreign Military Sales payment schedule?
payment schedules (when applicable per Table C9.T17 Requirements) provide forecasted financial requirements for an case and project the timing and/or amounts of international partner deposits needed to meet the requirements. Payment schedules for documents are prepared by the Case Writing and Development Division (CWD) during the case development process based upon inputs (i.e., source of supply, lead time, delivery schedules, period of performance, progress payment schedules) provided by the . Implementing DoW components are expected to continually monitor case-level cash advances and validate the accuracy of payment schedules. The estimated normally includes specific dates when each payment is due and consists of two financial categories:

The terms of sale and the estimated payment schedule on the sample LOA in SAMM Figure C5.F8. Bandaria is the manual's fictional training country; the figures are the SAMM's example, not a real case. The first page states the estimated cost, the initial deposit and the terms of sale; the second sets out the payments the purchaser should plan for, quarter by quarter.
Payment schedules, to include initial deposits, are built upon assumptions and inputs such as source of supply, lead time, delivery schedules, period of performance, progress payment schedules, etc. Payment schedules are built, using , at the line level (or sub-line or delivery-set level), and rolled-up, to a case-level schedule. Payment schedules are prepared using pricing estimates and estimated dates for the following: acceptance, case implementation, requisition initiation, contract awards, contractor payments, physical deliveries, and incurrence of personnel costs. Other information required to prepare the include contractor termination schedules (used in the ), lead times and/or availability, periods of performance, and disbursement histories for like-item cases or lines already implemented. Each deposit amount covers all costs estimated to be incurred on the international partner’s behalf during the payment period, plus a reserve to cover (for sales from procurement). Costs may include such items as anticipated deliveries of services and stock items, and on contracts. This information is needed at the line level and must be provided by the to (IOPS/GEX/CWD) for preparation.
Typically, the projects quarterly payments due by the 15th day of March, June, September, and December per Table C9.T16. Exceptions to these dates must be approved by the Office of Business Operations (OBO).
updates are necessary to reflect revisions to delivery schedules, scope changes, pricing updates, actual dates, contractor payment milestone revisions, etc. To determine whether an update is needed, reviews occur at least annually as part of the case review and reconciliation process. Payment schedules must be evaluated for possible changes when a modification or amendment is processed.
