A chart in yesterday's Federal Report incorrectly identified the source of the names of defense contractors whose public relations expenses were challenged by Pentagon auditors. The source was Rep. Fortney H. (Pete) Stark Jr. (D-Calif.).

These are public relations expenditures by defense contractors that have been challenged by the Defense Contract Audit Agency in recent years. In July 1984, the agency supplied the list, which covers expenditures in fiscal 1981 in some cases and 1982 in others, to the House Government Operations subcommittee on legislation and national security. The agency did not identify the contractors by name, but the subcommittee staff did.

The Defense Department allows contractors to include certain kinds of public relations expenses in the payments they receive for overhead costs associated with defense contracts. The challenged expenses include. among other things, the sponsorship of a theater at Marriott's Great America theme park, a relocation bonus for an employe, press club dinners, gifts and advertising. In the case of Martin Marietta's Denver Aerospace Division, the DCAA subsequently authorized the payment of $90,985. Contractor..Amount Challenged by DCAA . . .
