[Funding for Air Force Cost Plus Fixed Fee Level of Effort Contract]

GAO commented on a request from an Air Force contracting officer to determine whether a contract for support services is severable or nonseverable for obligational purposes. GAO noted that the Air Force treatment of modifications to cost-plus-fixed-fee level of effort contracts for Launch Vehicle Integration analysis and support as severable services and charging the cost against appropriations current when the services were rendered was presumptively reasonable and nothing in the record overcomes presumption.
