Before award, the contracting officer and all other members of the acquisition team must limit access to information concerning the Government cost estimate to Government personnel whose official duties require knowledge of the estimate and to non-Government personnel with a need to know and who have signed a non-disclosure agreement (contracting officers may tailor the non-disclosure agreement at Figure  1 for these purposes). After award, the contracting officer may reveal the total amount of the Government estimate upon request. The contracting officer is not authorized to release the basis for calculating the estimate at any time.
