Schedule Of Unallocated Items and Eliminations

Unallocated items and eliminations includes costs not attributable to business segments as well as intercompany profit eliminations. We generally allocate costs to business segments based on the U.S. federal cost accounting standards. Unallocated pension and other postretirement expense represents the portion of pension and other postretirement costs that are not recognized by business segments for segment reporting purposes. The business segments have traditionally been allocated pension and other postretirement costs using U.S. Government Cost Accounting Standards (CAS), which employ different actuarial assumptions and accounting conventions than Generally Accepted Accounting Principles in the United States of America (GAAP). Beginning in 2013, pension costs, comprising GAAP service and prior service costs, are allocated to Commercial Airplanes. BDS continues to be allocated CAS pension costs which are allocable to government contracts. Other postretirement costs will continue to be allocated to business segments based on CAS, which is generally based on benefits paid. Prior year allocations have not been adjusted. Components of Unallocated items and eliminations are shown in the following table.
