Impairment Of Goodwill And Other Assets [Abstract]
Impairment Of Goodwill And Other Long-Lived Assets	Note N — Impairment of Goodwill and Other Assets We test our goodwill and other indefinite-lived intangible assets for impairment annually, or under certain circumstances, more frequently, such as when events or circumstances indicate there may be impairment. 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 and review of our financial statements for the quarter ended January 1, 2016, we performed an interim review 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 a preliminary 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 preliminarily 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 review, we also conducted a review 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 review. 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 reviews, we concluded that goodwill and other assets related to Harris CapRock Communications were impaired as of the end of the quarter ended January 1, 2016, and we recorded an estimated non-cash impairment charge of $367 million ($328 million after-tax), of which $290 million related to goodwill. Due to the length of time necessary to measure the impairment of goodwill and other assets, our impairment analysis is not complete and is subject to change. We expect to complete our analysis prior to reporting our financial results for the third quarter of fiscal 2016 and will record any adjustments to our preliminary estimate at that time. Most of the $367 million estimated impairment charge is not deductible for tax purposes. The tax effect of that non-deductibility was treated as a discrete item in the quarter ended January 1, 2016 for purposes of calculating our effective tax rate. We do not expect to make any current or future cash expenditures as a result of the impairment. The estimated impairment will 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.
