Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies Litigation In the normal course of business, the Company is named as a defendant in various legal proceedings in which claims are asserted against the Company. We record accruals for loss contingencies based on the circumstances of each claim, when it is probable that a loss has been incurred as of the balance sheet date and can be reasonably estimated.

On April 26, 2017, the sellers of 7S, a company we acquired in 2015, formally disputed the contingent consideration related to the acquisition and are claiming an additional $23.9 (€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.

The guarantees primarily relate to operating leases and indebtedness. The stand-by letters of credit relate to insurance requirements and debt facilities.
