GAO commented on proposed revisions to the Federal Acquisition Regulation (FAR) that would: (1) allow contractors the costs of postretirement benefits other than pensions only if paid currently; (2) provide for the government to receive an equitable share of amounts reverting to a contractor upon termination or reduction of a previously funded plan for postretirement benefits; (3) affect the timing of reimbursements and progress payments with respect to certain fringe benefits; and (4) revise the minimum dollar threshold from $100 to $250 in contract clauses relating to taxes. GAO had no objection to the proposed changes.
