Do not pay a request for equitable adjustment exceeding the simplified acquisition threshold unless the contractor certifies the request per clause 252.243-7002.
For unpriced change orders exceeding $5 million, ensure definitization schedules provide for definitization within 180 days of issuance or by the date obligations reach 50 percent of the not-to-exceed price, whichever is earlier.
Do not obligate more than 50 percent of the not-to-exceed price on an unpriced change order before definitization. If the contractor submits a qualifying proposal before that threshold, you may increase the limit to 75 percent.

Inquiries: Send questions about this deviation to osd.pentagon.ousd-a-s.mbx.dfars@mail.mil.

FMS and Special Access Programs: Unpriced change orders for FMS and special access programs are exempt from the definitization requirements at 243.370. Contracting officers must still apply the policy to the maximum extent practicable. Prior notice to the Office of the Principal Director, Defense Pricing, Contracting, and Acquisition Policy is required when adherence is impracticable.

Waiver Authority: The head of the agency may waive limitations on price ceiling, definitization schedule and obligations for unpriced change orders supporting a contingency operation or a humanitarian or peacekeeping operation.

Allowable Profit on Late Definitization: When a final price is negotiated after substantial performance, the head of the contracting activity must ensure profit reflects reduced cost risk and the extent of costs incurred before definitization. Document the risk assessment in the price negotiation memorandum.
