Restructuring and Other Reorganization-Related Costs [Abstract] |
Restructuring and Related Activities Disclosure [Text Block] | Restructuring and Other Reorganization-Related Liabilities 2013 Restructuring Plan In the fourth quarter of 2013, we implemented a cost savings initiative (the "2013 Plan") to better align our cost structure with our revenue, primarily in Continental Europe. During the three months ended March 31, 2015, we recorded $0.1 of net reversals for the 2013 Plan within the IAN segment related to changes in the estimate of lease termination costs, which was included in office and general expenses within our unaudited Consolidated Statements of Operations. All restructuring actions were substantially completed by the end of the first quarter of 2014, with remaining payments expected to be made through 2021. A summary of the 2013 Plan restructuring liability activity is listed below.
