[1] | Net sales and operating profit vary from the amounts previously reported on Form 10-Q as a result of our former IS&GS business being classified as discontinued operations in the third quarter of 2016, which is reflected for all periods presented.
[2] | The third quarter of 2016 includes the results of AWE from August 26, 2016, the date we obtained controlling interest, including approximately $103 million in net sales and $104 million in net earnings. Third quarter net earnings includes a non-cash gain on the step acquisition of AWE (see "Note 3 - Acquisitions and Divestitures"). The fourth quarter of 2016 includes the results of AWE for the entire quarter, including approximately $307 million in net sales and $2.9 million in net earnings.
[3] | The third quarter of 2016 includes a net gain of $1.2 billion related to the divestiture of our former IS&GS business.
[4] | The first quarter of 2016 varies from the amounts previously reported on Form 10-Q as a result of adopting ASU No. 2016-09 (see "Note 1 - Significant Accounting Policies").
[5] | AOCL related to postretirement benefit plans is shown net of tax benefits at December 31, 2016, 2015 and 2014 of $6.5 billion, $6.2 billion and $6.4 billion. These tax benefits include amounts recognized on our income tax returns as current deductions and deferred income taxes, which will be recognized on our tax returns in future years. See "Note 9 - Income Taxes" and "Note 11 -Postretirement Plans" for more information on our income taxes and postretirement benefit plans.
[6] | The fourth quarter of 2015 includes the results of Sikorsky since the November 6, 2015 acquisition date through December 31, 2015, including approximately $400 million in net sales and about $45 million in operating loss, inclusive of intangible amortization and adjustments required to account for the acquisition.
[7] | FAS pension expense, CAS pension costs and severance charges reflect the reclassification for discontinued operations presentation of benefits related to former IS&GS salaried employees (see "Note 11 - Postretirement Plans").
[8] | The higher CAS pension cost primarily reflects the impact of phasing in CAS Harmonization.
[9] | See "Note 15 - Restructuring Charges" for information on charges related to certain severance actions at our business segments. Severance charges for initiatives that are not significant are included in business segment operating profit.
[10] | Other, net in 2015 includes a non-cash asset impairment charge of approximately $90 million related to our decision in 2015 to divest our LMCFT business (see "Note 3 - Acquisitions and Divestitures"). This charge was partially offset by a net deferred tax benefit of about $80 million, which is recorded in income tax expense. The net impact reduced net earnings by about $10 million.
[11] | Other, net in 2015 includes approximately $38 million of non-recoverable transaction costs associated with the acquisition of Sikorsky.
[12] | Total depreciation and amortization in the table above excludes $48 million, $81 million and $67 million for the years ended December 31, 2016, 2015 and 2014 related to the former IS&GS business segment. These amounts are included in depreciation and amortization in our consolidated statements of cash flows as we did not reclassify our cash flows to exclude the IS&GS business segment. See "Note 3 - Acquisitions and Divestitures" for more information.
[13] | Total capital expenditures in the table above excludes $9 million, $31 million and $18 million for the years ended December 31, 2016, 2015 and 2014 related to the former IS&GS business segment. These amounts are included in capital expenditures in our consolidated statements of cash flows as we did not reclassify our cash flows to exclude the IS&GS business segment. See "Note 3 - Acquisitions and Divestitures" for more information.
[14] | Total net periodic benefit cost associated with our qualified defined benefit plans represents pension expense calculated in accordance with GAAP (FAS pension expense). We are required to calculate pension expense in accordance with both GAAP and CAS rules, each of which results in a different calculated amount of pension expense. The CAS pension cost is recovered through the pricing of our products and services on U.S. Government contracts and, therefore, is recognized in net sales and cost of sales for products and services. We include the difference between FAS pension expense and CAS pension cost, referred to as the FAS/CAS pension adjustment, as a component of other unallocated, net on our consolidated statements of earnings. The FAS/CAS pension adjustment, which was $902 million in 2016, $400 million in 2015, and $317 million in 2014, effectively adjusts the amount of CAS pension cost in the business segment operating profit so that pension expense recorded on our consolidated statements of earnings is equal to FAS pension expense. FAS pension expense and CAS pension costs reflect the reclassification for discontinued operations presentation of benefits related to former IS&GS salaried employees.
[15] | We have no long-lived assets with material carrying values located in foreign countries.
[16] | Corporate assets primarily include cash and cash equivalents, deferred income taxes, environmental receivables and investments held in a separate trust.
