Restructuring and Related Activities [Abstract]
Restructuring	Restructuring In the fourth quarter of 2016, we committed to a restructuring plan to lower our operating costs (the “Cost Alignment Plan”). The Cost Alignment Plan primarily consists of a reduction in workforce, and business process initiatives that will be substantially implemented prior to the end of 2019. Business process initiatives primarily include plans to reduce operating costs of our distribution and pharmacy operations, administrative support functions, and technology platforms, as well as the disposal and abandonment of certain non-core businesses. As a result of the Cost Alignment Plan, we expect to record total pre-tax charges of approximately $250 million to $270 million, of which $246 million of pre-tax charges were recorded to date. Estimated remaining charges primarily consist of exit-related costs and accelerated depreciation and amortization, which are largely attributed to our Distribution Solutions segment. During the first quarter of 2017, we recorded a pre-tax charge of $9 million as part of the Cost Alignment Plan. There were no material restructuring charges recorded during the first quarter of 2018. During the first quarters of 2018 and 2017, we made $14 million and $45 million of cash payments, primarily related to severance. The reserve balances as of June 30, 2017 and March 31, 2017 include $64 million and $71 million recorded in other accrued liabilities, and $35 million recorded in other noncurrent liabilities in our condensed consolidated balance sheet.
