Acquisitions	9 Months Ended
Sep. 30, 2018
Business Combinations [Abstract]
Acquisitions	Acquisitions From time to time, we acquire and invest in companies throughout the world, including franchises. For the nine months ended September 30, 2018, the total cash consideration for acquisitions, net of cash acquired, was $50.9, the majority of which took place in the Netherlands. This balance includes initial acquisition payments of $8.2 and contingent consideration payments of $42.7 ($18.6 of which was recognized as a liability at the acquisition date). During the nine months ended September 30, 2017, the total cash consideration for acquisitions, net of cash acquired, was $40.2, which includes initial acquisition payments of $27.3 and contingent consideration related to previous acquisitions of $12.9, of which $10.3 was related to our 2015 acquisition of 7S Group GmbH ("7S") in Germany. On April 26, 2017, the sellers of 7S formally disputed the contingent consideration related to the acquisition and are claiming an additional $24.1 (€20.8), plus interest. We believe no further amounts are due and intend to vigorously dispute their claims in arbitration. We are not currently able to predict the outcome of the arbitration or the timing of any resolution, and consequently, no amounts have been recorded in the Consolidated Financial Statements. As of January 1, 2018, we adopted the new accounting guidance on statement of cash flows. The guidance provides classification requirements for certain cash receipts and cash payments. During the first nine months of 2018, we classified $24.1 of payments which were in excess of the contingent consideration liabilities initially recognized on the acquisition date as operating cash flows. The excess cash payments for contingent consideration liabilities made during the first nine months of 2017 were not material.
