(B) Agency determination (i) In general Upon receipt of a notice described under subparagraph (A), the OSDBU shall verify whether such lack of payment has occurred and determine whether such lack of payment is due to an undue restriction placed on the prime contractor by an action of the Federal agency. (ii) Response during determination During the period in which the OSDBU is making the determination under clause (i), the prime contractor may respond to both the subcontractor and the OSDBU with relevant verifying documentation to either prove payment or allowable status of nonpayment. (C) Cure period If the OSDBU verifies the lack of payment under subparagraph (B) and determines that such lack of payment is not due to an action of the Federal agency, the OSDBU shall notify the prime contractor and provide the prime contractor with a 15-day period in which the prime contractor may make the payment owed to the subcontractor. (D) Result of nonpayment If, after notifying the prime contractor under subparagraph (C), the OSDBU determines that the prime contractor has not fully paid the amount owed within the 15-day cure period described under subparagraph (C), the OSDBU shall ensure that such failure to pay is reflected in the Contractor Performance Assessment Reporting system (or any successor system). . 3.
