Information on Business Segments

We operate in four business segments: Aeronautics, MFC, RMS and Space. We organize our business segments based on the nature of the products and services offered. Following is a brief description of the activities of our business segments:


•	Aeronautics – Engaged in the research, design, development, manufacture, integration, sustainment, support and upgrade of advanced military aircraft, including combat and air mobility aircraft, unmanned air vehicles and related technologies.


•	Missiles and Fire Control – Provides air and missile defense systems; tactical missiles and air-to-ground precision strike weapon systems; logistics; fire control systems; mission operations support, readiness, engineering support and integration services; manned and unmanned ground vehicles; and energy management solutions.

•

Rotary and Mission Systems – Provides design, manufacture, service and support for a variety of military and commercial helicopters; ship and submarine mission and combat systems; mission systems and sensors for rotary and fixed-wing aircraft; sea and land-based missile defense systems; radar systems; the Littoral Combat Ship (LCS); simulation and training services; and unmanned systems and technologies. In addition, RMS supports the needs of customers in cybersecurity and delivers communications and command and control capability through complex mission solutions for defense applications.

•

Space – Engaged in the research and development, design, engineering and production of satellites, space transportation systems, and strategic, advanced strike, and defensive systems. Space provides network-enabled situational awareness and integrates complex space and ground global systems to help our customers gather, analyze and securely distribute critical intelligence data. Space is also responsible for various classified systems and services in support of vital national security systems. Prior to August 24, 2016, the date we obtained control of AWE we accounted for the venture using the equity method of accounting with 33% of AWE’s earnings or losses recognized by Space. Subsequent to August 24, 2016, we obtained control of AWE and 100% of AWE’s sales and 51% of AWE’s earnings have been included in our consolidated results of operations. Accordingly, the consolidated results of operations for the year ended December 31, 2016 do not reflect a full year of AWE operations. Operating profit for our Space business segment also includes our share of earnings for our investment in ULA, which provides expendable launch services to the U.S. Government.

The financial information in the following tables includes the results of businesses we have acquired from their respective dates of acquisition and excludes businesses included in discontinued operations (see “Note 3 – Acquisition and Divestitures”) for all years presented. Net sales of our business segments exclude intersegment sales as these activities are eliminated in consolidation.

Operating profit of our business segments includes our share of earnings or losses from equity method investees as the operating activities of the equity method investees are closely aligned with the operations of our business segments. ULA, results of which are included in our Space business segment, is our primary equity method investee. Operating profit of our business segments excludes the FAS/CAS operating adjustment for our qualified defined benefit pension plans (described below); the adjustment from CAS to FAS service cost component for all other postretirement benefit plans; expense for stock-based compensation; the effects of items not considered part of management’s evaluation of segment operating performance, such as charges related to significant severance and restructuring actions (see “Note 15 – Severance and Restructuring Charges”) and goodwill impairments; gains or losses from significant divestitures; the effects of certain legal settlements; corporate costs not allocated to our business segments; and other miscellaneous corporate activities. These items are included in the reconciling item “Unallocated items” between operating profit from our business segments and our consolidated operating profit. See “Note 1 – Significant Accounting Policies” (under the caption “Use of Estimates”) for a discussion related to certain factors that may impact the comparability of net sales and operating profit of our business segments.

Our business segments’ results of operations include pension expense only as calculated under U.S. Government Cost Accounting Standards (CAS), which we refer to as CAS pension cost. We recover CAS pension cost through the pricing of our products and services on U.S. Government contracts and, therefore, the CAS pension cost is recognized in each of our business segments’ net sales and cost of sales. Our consolidated operating profit in our consolidated financial statements must present the service cost component of FAS pension and other postretirement benefit plan expense calculated in accordance with FAS requirements under U.S. GAAP. The operating portion of the net FAS/CAS operating adjustment represents the difference between the service cost component of FAS pension expense and the CAS pension cost recorded in our business segments’ results of operations. The non-service FAS pension and other postretirement benefit plan cost component is included in other non-operating expenses, net on our consolidated statement of earnings.

^(a)

On August 24, 2016, our ownership interest in the AWE joint venture increased from 33% to 51% and we were required to change our accounting for this investment from the equity method to consolidation. As a result of the increased ownership interest, we recognized a non-cash gain of $127 million at our Space business segment, which increased net earnings from continuing operations by $104 million ($0.34 per share) in 2016. See “Note 3 – Acquisition and Divestitures” for more information.


^(b)	The FAS/CAS operating adjustment represents the difference between the service cost component of FAS pension expense and total pension costs recoverable on U.S. Government contracts as determined in accordance with CAS. For a detail of the FAS/CAS operating adjustment and the total net FAS/CAS pension adjustment, see the table below.


^(c)	See “Note 15 – Severance and Restructuring Charges” for information on charges related to certain severance actions at our business segments. Severance and restructuring charges for initiatives that are not significant are included in business segment operating profit.

^(d)

Other, net in 2018 includes a non-cash asset impairment charge of $110 million related to our equity method investee, AMMROC (see “Note 1 – Significant Accounting Policies”). Other, net in 2017 includes a previously deferred non-cash gain of $198 million related to properties sold in 2015 as a result of completing our remaining obligations (see “Note 8 – Property, Plant and Equipment, net”) and a $64 million charge, which represents our portion of a non-cash asset impairment charge recorded by AMMROC (see “Note 1 – Significant Accounting Policies”).

Total net FAS/CAS pension adjustments, including the service and non-service cost components of FAS pension expense, were as follows (in millions):



	2018			2017			2016
Total FAS expense and CAS costs
FAS pension expense	$	(1,431	)	$	(1,372	)	$	(1,019	)
Less: CAS pension cost	2,433			2,248			1,921
Net FAS/CAS pension adjustment	$	1,002		$	876		$	902

Service and non-service cost reconciliation
FAS pension service cost	(630		)	(635		)	(671		)

Net FAS/CAS pension adjustment	$	1,002		$	876		$	902

^(a)

We record the non-service cost components of net periodic benefit cost as part of other non-operating expense, net in the consolidated statement of earnings. The non-service cost components in the table above relate only to our qualified defined benefit pension plans. We incurred total non-service costs for our qualified defined benefit pension plans in the table above, along with similar costs for our other postretirement benefit plans of $67 million, $109 million, and $123 million for the years ended 2018, 2017 and 2016.

We recover CAS pension cost through the pricing of our products and services on U.S. Government contracts and, therefore, recognize CAS pension cost in each of our business segment’s net sales and cost of sales. Our consolidated financial statements must present FAS pension and other postretirement benefit plan expense calculated in accordance with FAS requirements under U.S. GAAP. The operating portion of the net FAS/CAS pension adjustment represents the difference between the service cost component of FAS pension expense and CAS pension cost. The non-service FAS pension cost component is included in other non-operating expense, net on our consolidated statements of earnings. The net FAS/CAS pension adjustment increases or decreases CAS pension cost to equal total FAS pension expense (both service and non-service).
