Commitments and Contingencies Disclosure [Abstract]
Commitments And Contingencies	COMMITMENTS AND CONTINGENCIES Commitments At June 30, 2017, the Company had outstanding letters of credit and bond obligations of $22.4 related to performance guarantees. The Company believes that any guarantee obligation that may arise will not be material. The Company also has future purchase commitments with telecommunication and transportation providers of $8.4 for the remainder of 2017. Contingencies The Company, from time to time, is subject to various loss contingencies, including tax and legal contingencies that arise in the ordinary course of business. The Company accrues for a loss contingency when it is probable that a liability has been incurred and the amount of such loss can be reasonably estimated. At this time, the Company believes that any such contingencies, either individually or in the aggregate, will not have a materially adverse effect on the Company’s results of operations or financial condition. However, the outcome of litigation cannot be predicted with certainty, and unfavorable resolution of one or more pending matters could have a materially adverse impact on the Company’s results of operations or financial condition in the future.
