NOTE 5 – BUSINESS SEGMENTS INFORMATION

We operate in five business segments: Aeronautics, IS&GS, Missiles and Fire Control (MFC), MST and Space Systems. We organize our business segments based on the nature of the products and services offered. The results of our MST business segment include the operations of Sikorsky since its November 6, 2015 acquisition date. Accordingly, the financial results of Sikorsky operations are included in the financial results of our MST business segment for the quarter and six months ended June 26, 2016 but not for the quarter and six months ended June 28, 2015.

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. United Launch Alliance (ULA), which is part of our Space Systems business segment, is our primary equity method investee. Operating profit of our business segments excludes the FAS/CAS pension adjustment described below; 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 goodwill impairments and significant severance actions; gains or losses from 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 10 (under the caption “Changes in 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. Since our consolidated financial statements must present pension expense calculated in accordance with the financial accounting standards (FAS) requirements under GAAP, which we refer to as FAS pension expense, the FAS/CAS pension adjustment increases or decreases the CAS pension cost recorded in our business segments’ results of operations to equal the FAS pension expense.
