As discussed in Note O — Business Segments, we adjusted our segment reporting in the first quarter of fiscal 2016 to reflect our new organizational structure that was 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 have reassigned goodwill using a relative fair value approach. Because our accounting for our acquisition of Exelis Inc. and its subsidiaries (collectively, “Exelis”) in the fourth quarter of fiscal 2015 is still preliminary, we assigned the goodwill acquired as a result of the acquisition on a provisional basis. Immediately before and after our goodwill assignments, we completed an assessment of any potential goodwill impairment under our former and new segment reporting structure and determined that no impairment existed.

(1) Our accounting for the Exelis acquisition is still preliminary. The fair value estimates for the assets acquired and liabilities assumed were based on preliminary calculations, and our estimates and assumptions are subject to change as we obtain additional information for our estimates during the measurement period (up to one year from the acquisition date). The primary areas of these preliminary estimates that are not yet finalized relate to certain tangible assets and liabilities acquired, identifiable intangible assets and tax-related items. During the quarter ended October 2, 2015, we recorded several purchase price adjustments which impacted goodwill, the largest of which was a $31 million reduction in current liabilities related to unrecognized tax benefits.
