^(a)	In the first quarter of 2017, we recognized a $64 million charge, which represents our portion of a noncash asset impairment charge recorded by an international equity method investee. See “Note 9 – Other” (under the caption “Equity Method Investee Impairment”) for more information.

^(b)

As a result of the IS&GS divestiture in August 2016, we reclassified $35 million of general corporate overhead costs incurred in the first quarter of 2016 and previously allocated to the IS&GS business segment. These costs were not reported as discontinued operations because they were not directly attributable to the IS&GS business and will continue to be incurred by us. See “Note 3 – Divestitures” for more information.
