## Abstract

The Civilian Agency Acquisition Council and the Defense Acquisition Regulations Council (Councils) have agreed on a final rule amending the Federal Acquisition Regulation (FAR) by revising language pertaining to the Cost Accounting Standards Administration, and the related FAR contract clause, Administration of Cost Accounting Standards. In addition, a new contract clause is added, Proposal Disclosure--Cost Accounting Practice Changes. The rule describes the process for determining and resolving the cost-impact on contracts and subcontracts when a contractor makes a compliant change to a cost accounting practice or follows a noncompliant practice. To assist in understanding the changes between the current FAR rule and this final FAR rule, a matrix that summarizes the major changes is provided in Section C, Supplementary Information, below.
