(d) The contractor has a duty to ensure that financing payments to subcontractors conform to the standards and principles prescribed in paragraph (j) of the Progress Payments clause in the prime contract. Although the contracting officer should, to the extent appropriate, review the subcontract as part of the overall administration of progress payments in the prime contract, there is no special requirement for contracting officer review or consent merely because the subcontract includes financing payments, except as provided in paragraph (c) of this section. However, the contracting officer must ensure that the contractor has installed the necessary management control systems, including internal audit procedures.
