| GOODWILL                | GOODWILLAs discussed in Note 1: Significant Accounting Policies and Note 24: Business Segments, we implemented a new organizational structure effective at the beginning of fiscal 2016, which resulted in changes to our operating segments, which are also our reportable segments and are referred to as our business segments. In accordance with GAAP, we reassigned goodwill using a relative fair value approach. Immediately before and after our goodwill assignments, we completed an assessment of any potential goodwill impairment under our former and new reporting structure and determined that no impairment existed. Indications of potential impairment of goodwill related to Harris CapRock Communications (which is part of our Critical Networks segment) were present at the end of the quarter ended January 1, 2016 due to the downturn in the energy market and its impact on customer operations, which also resulted in a decrease in the fiscal 2016 outlook for Harris CapRock Communications. Consequently, in connection with the preparation of our financial statements for the quarter ended January 1, 2016, we performed an interim test of Harris CapRock Communications’ goodwill for impairment as of the end of the quarter ended January 1, 2016. To test for potential impairment of goodwill related to Harris CapRock Communications, we prepared an estimate of the fair value of the reporting unit based on projected discounted cash flows. The current carrying value of the Harris CapRock Communications reporting unit exceeded its estimated fair value, and accordingly, we allocated the estimated fair value to the assets and liabilities of the Harris CapRock Communications reporting unit to estimate the implied fair value of goodwill.In conjunction with the above-described impairment test, we also conducted a test for impairment of other assets related to Harris CapRock Communications, including amortizable intangible assets and fixed assets, and impairment of these assets was considered prior to the conclusion of the goodwill impairment test. The estimated fair value of these other assets related to Harris CapRock Communications was determined based, in part, on an analysis of projected cash flows.As a result of these impairment tests, we concluded that goodwill and other assets related to Harris CapRock Communications were impaired as of January 1, 2016, and we recorded an estimated non-cash impairment charge of $367 million, of which $290 million related to goodwill, in the quarter ended January 1, 2016. Due to the length of time necessary to measure the impairment of goodwill and other assets, our impairment analysis as of January 1, 2016 was preliminary. During the quarter ended April 1, 2016, we completed our impairment analysis which indicated that no adjustment was necessary to the impairment charge recorded during the quarter ended January 1, 2016. Most of the $367 million impairment charge is not deductible for tax purposes. See Note 23: Income Taxes for the tax impact related to this impairment charge. The impairment does not cause us to be in noncompliance with the covenants under our credit arrangements, and we do not expect the impairment to impact our ongoing financial performance, although no assurances can be given.The assignment of goodwill by business segment, and changes in the carrying amount of goodwill for the fiscal years ended July 1, 2016 and July 3, 2015, by business segment, were as follows: Communication Systems Space and Intelligence Systems Electronic Systems Critical Networks Total           (In millions)Balance at June 27, 2014$439 $131 $85 $1,056 $1,711Goodwill acquired326 1,313 1,632 1,424 4,695Goodwill decrease from divestitures— — — (24) (24)Currency translation adjustments(5) 2 1 (32) (34)Balance at July 3, 2015760 1,446 1,718 2,424 6,348Impairment of goodwill— — — (290) (290)Goodwill decrease from divestitures (1)— — (61) — (61)Currency translation adjustments7 (1) (28) (40) (62)Other (including adjustments to previously estimated fair value of assets acquired and liabilities assumed)14 33 21 (28) 40Balance at July 1, 2016$781 $1,478 $1,650 $2,066 $5,975 (1)  During the fourth quarter of fiscal 2016, we completed the divestiture of Aerostructures. In accordance with GAAP, we determined $61 million of goodwill to be a part of the carrying value of Aerostructures in determining the gain or loss on divestiture. See Note 3: Discontinued Operations and Divestitures for additional information.See Note 4: Business Combinations for additional information regarding adjustments to previously estimated fair value of assets acquired and liabilities assumed. |
