Obviously, part of your review will be to determine if the proposed items and costs meet your country’s needs and budgetary constraints. If you want to request any changes to the offer based on your review, your change request must be submitted to the IA for consideration prior to your acceptance (signature) on the LOA. “Pen and ink” changes to the LOA should be discussed with the IA if they are minor administrative or corrective changes. “Pen and ink” changes to a LOA may be accepted by the IA prior to FMS case signature. If the “pen and ink” change alters the scope or revises the terms of sale or total costs, this will normally be considered a counter offer that will require a new LOR.

If your government signs an LOA and includes any changes that have not been authorized by the IA, we will consider this to be a "counter-offer." Depending on the extent of the proposed changes, the LOA may be re-stated and re-offered, or a new LOA might be prepared.

The initial deposit is an integral part of acceptance and is also required on or before the OED. The LOA contains instructions for sending the required initial payment to the Defense Finance and Accounting Service (DFAS). Payment must be in U.S. dollars and may be transmitted by check or wire transfer.
