Segment Reporting [Abstract]

Segment Information

Segment Information

Our primary profitability measurements to review a segment’s operating results are Earnings from operations and operating margins. See page 6 for a Summary of Business Segment Data, which is an integral part of this note.

In November 2016, we announced plans for the formation of Boeing Global Services (BGS), which will bring together certain Commercial Aviation Services businesses, currently included in the Commercial Airplanes segment, and certain BDS businesses (primarily those currently included in the Global Services & Support (GS&S) segment). We expect Boeing Global Services to be operational during the second half of 2017. We will continue to report using the existing segment structure until BGS is operational and has discrete financial information that is being provided to the Chief Operating Decision Maker.

Intersegment revenues, eliminated in Unallocated items, eliminations and other, are shown in the following table.

	Three months ended March 31
	2017		2016
Commercial Airplanes		$597		$428
Boeing Capital	5		5
Total		$602		$433

Unallocated Items, Eliminations and other

Unallocated items, eliminations and other 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. Components of Unallocated items, eliminations and other are shown in the following table.

Unallocated Pension and Other Postretirement Benefit Expense

Unallocated pension and other postretirement benefit expense represent the portion of pension and other postretirement benefit costs that are not recognized by business segments for segment reporting purposes. Pension costs, comprising Generally Accepted Accounting Principles in the United States of America (GAAP) service and prior service costs, are allocated to Commercial Airplanes. Pension costs are allocated to BDS using U.S. Government Cost Accounting Standards (CAS), which employ different actuarial assumptions and accounting conventions than GAAP. These costs are allocable to government contracts. Other postretirement benefit costs are allocated to business segments based on CAS, which is generally based on benefits paid.
