Restructuring and Related Activities [Abstract]
Restructuring Costs	Restructuring Costs Restructuring costs are reported by the same name in the accompanying consolidated statements of income. IT Restructuring Plan Management is focused on a margin recovery plan that includes identification and implementation of various profit improvement initiatives. To that end, we began a plan to restructure our information technology department (the “IT Restructuring Plan”) in 2018. In early 2019, we have entered into services agreements with Infosys Limited under which Infosys manages certain of our information technology services. We expect to complete the IT Restructuring Plan by the end of 2019, incurring cumulative total costs of approximately $15 million in the Other segment. This total has decreased compared with the $20 million reported in the 2018 Form 10-K due to more of our IT employees transitioned to Infosys than originally contemplated, resulting in lower one-time termination benefit costs. As of March 31, 2019, we had incurred cumulative restructuring costs under the IT Restructuring Plan of $11 million, including $7 million of one-time termination benefits and $4 million of other restructuring costs (consulting fees). As of December 31, 2018, there was $6 million accrued under the IT Restructuring Plan, primarily for one-time termination benefits that require cash settlement. In the first quarter of 2019, we incurred $2 million of other restructuring costs, and paid $2 million to settle one-time termination benefits and $1 million to settle other restructuring costs. As of March 31, 2019, there was $5 million accrued under the IT Restructuring Plan. 2017 Restructuring Plan As of December 31, 2018, we had $18 million of accrued liabilities for the 2017 Restructuring Plan. In the first quarter of 2019, we incurred $1 million of restructuring costs for adjustments to previously recorded lease contract termination costs implemented pursuant to the restructuring and profitability improvement plan approved by our Board in June 2017 (the “2017 Restructuring Plan”), and paid $3 million to settle one-time termination and lease contract termination costs. As of March 31, 2019, there was $16 million accrued for lease contract termination costs under the 2017 Restructuring Plan. We expect to continue to settle these liabilities through 2025, unless the leases are terminated sooner.
