(c) The Contractor shall not include in any proposal any cost that is unallowable, as defined in subpart 2.1 of the FAR, or an executive agency supplement to the FAR.
(d) If the Contracting Officer determines that a cost submitted by the Contractor in its proposal is expressly unallowable under a cost principle in the FAR, or an executive agency supplement to the FAR, that defines the allowability of specific selected costs, the Contractor shall be assessed a penalty equal to–
(1) The amount of the disallowed cost allocated to this contract; plus
(2) Simple interest, to be computed-
(i) On the amount the Contractor was paid (whether as a progress or billing payment) in excess of the amount to which the Contractor was entitled; and
(ii) Using the applicable rate effective for each six-month interval prescribed by the Secretary of the Treasury pursuant to Pub.L.92-41 (85 Stat.97).
(e) If the Contracting Officer determines that a cost submitted by the Contractor in its proposal includes a cost previously determined to be unallowable for that Contractor, then the Contractor will be assessed a penalty in an amount equal to two times the amount of the disallowed cost allocated to this contract.
(f) Determinations under paragraphs (d) and (e) of this clause are final decisions within the meaning of 41 U.S.C. chapter 71, Contract Disputes.
(g) Pursuant to the criteria in FAR 42.709-6, the Contracting Officer may waive the penalties in paragraph (d) or (e) of this clause.
