Acquisitions	3 Months Ended
Mar. 31, 2019
Business Combinations [Abstract]
Acquisitions	Acquisitions From time to time, we acquire and invest in companies throughout the world, including franchises. For the three months ended March 31, 2019, the total cash consideration paid for acquisitions, net of cash acquired, was $0.6, which represents contingent consideration payments related to previous acquisitions. For the three months ended March 31, 2018, the total cash consideration for acquisitions, net of cash acquired, was $41.0, the majority of which took place in the Netherlands. This balance includes initial acquisition payments of $8.2 and contingent consideration payments of $32.8 ($8.7 of which had been recognized as a liability at the acquisition date). On April 26, 2017, the sellers of 7S Group GmbH, a company we acquired in 2015, formally disputed the contingent consideration related to the acquisition and are claiming an additional $23.3 (€20.8), plus interest. The dispute has been heard by an arbitration tribunal in Germany, which is expected to render its decision during 2019. We have vigorously defended these claims in the arbitration, and we believe no further amounts are due. We are not currently able to predict the outcome of the arbitration, and consequently, no amounts have been recorded in the Consolidated Financial Statements.
