The Department issued a Final Rule revising the regulations covering contractor legal management requirements at 10 C.F.R. 719 (Federal Register May 3, 2013; http://www.gpo.gov/fdsys/pkg/FR-2013-05-03/pdf/2013-10485.pdf). It requires Contracting Officers to attempt to execute bilateral modifications to existing affected contracts. Attached is Acquisition Letter 2013-07, which provides suggested modification language. (The Final Rule's revisions are administrative in nature. Regarding costs contractors have not yet incurred, the revisions could have been communicated to contractors without using a Final Rule to incorporate them into existing contracts. Consequently, the modifications do not require equitable adjustments.)
