(c)(90) When a contractor submits additional cost or pricing data after the date of agreement on price, but before contract award (commonly referred to as a sweep), which is current as of the date of agreement on price, the contracting officer shall:
(i) require the contractor to provide a price impact summary which separately reflects price increase and price decrease impacts on the negotiated price;
(ii) allow only a downward price adjustment; a net zero adjustment may be considered when valid price increase offsets are present; and
(iii) require that the “as of” date on the Certificate of Current Cost or Pricing Data be the date of agreement on price rather than the date the additional data was submitted.
