Code of Federal Regulations Title 45. Public Welfare § 45.75.411 Adjustment of previously negotiated indirect (F & A) cost rates containing unallowable costs

(a) Negotiated indirect (F & A) cost rates based on a proposal later found to have included costs that:

(b) For rates covering a future fiscal year of the non–Federal entity, the unallowable costs will be removed from the indirect (F & A) cost pools and the rates appropriately adjusted.

(c) For rates covering a past period, the Federal share of the unallowable costs will be computed for each year involved and a cash refund (including interest chargeable in accordance with applicable regulations) will be made to the Federal Government. If cash refunds are made for past periods covered by provisional or fixed rates, appropriate adjustments will be made when the rates are finalized to avoid duplicate recovery of the unallowable costs by the Federal Government.

(d) For rates covering the current period, either a rate adjustment or a refund, as described in paragraphs (b) and (c) of this section, must be required by the cognizant agency for indirect costs. The choice of method must be at the discretion of the cognizant agency for indirect costs, based on its judgment as to which method would be most practical.

(e) The amount or proportion of unallowable costs included in each year's rate will be assumed to be the same as the amount or proportion of unallowable costs included in the base year proposal used to establish the rate.
