(a) Disagreement Constitutes a Dispute.—
(b) Amount of Adjustment.—
A contract price adjustment undertaken under section 1502(f)(2) of this title shall be made, where applicable, on relevant contracts between the Federal Government and the contractor that are subject to the cost accounting standards so as to protect the Federal Government from payment, in the aggregate, of increased costs, as defined by the Cost Accounting Standards Board. The Federal Government may not recover costs greater than the aggregate increased cost to the Federal Government, as defined by the Board, on the relevant contracts subject to the price adjustment unless the contractor made a change in its cost accounting practices of which it was aware or should have been aware at the time of the price negotiation and which it failed to disclose to the Federal Government.
The interest rate applicable to a contract price adjustment is the annual rate of interest established under section 6621 of the Internal Revenue Code of 1986 (26 U.S.C. 6621) for the period. Interest accrues from the time payments of the increased costs were made to the contractor or subcontractor to the time the Federal Government receives full compensation for the price adjustment.
