Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	We are involved in litigation from time to time in the ordinary course of business. A portion of the defense and/or settlement costs associated with such litigation is covered by various commercial liability insurance policies purchased by us and, in limited cases, indemnification from third parties. Our policy is to establish reserves for loss contingencies when the losses are both probable and reasonably able to be estimated. We record legal costs associated with loss contingencies as expenses in the period in which they are incurred. There have been no material updates or changes to the matters disclosed in Note 10 to Notes to Consolidated Financial Statements included in our Annual Report. We believe that the resolution of the matters disclosed in Note 10 to Notes to Consolidated Financial Statements included in our Annual Report will not have a material impact on our consolidated financial condition, results of operations or cash flows. We have estimated a reasonably possible range for all loss contingencies, including those disclosed in Note 10 to Notes to Consolidated Financial Statements included in our Annual Report and the item below, and believe it is reasonably possible that we could incur aggregate losses in addition to amounts currently accrued for all matters up to an additional $17,000 over the next several years, of which certain amounts would be covered by insurance or indemnity arrangements. In June 2019, we received a notification of assessment from tax and customs authorities in the Netherlands related to a VAT liability of approximately 16,800 Euros. The notification of assessment is related to our customs clearing and logistics business in the Netherlands, which we acquired through the acquisition of Bonded Services of America, Inc. and Bonded Services Acquisition, Ltd. (collectively, “Bonded”) in September 2017. As part of the import and declaration services we provide in the Netherlands, we file import declaration forms to the customs authorities for all goods imported in a particular month and calculate the amount of VAT that is due on the goods being imported. In certain instances, we remit import VAT to the Dutch tax authorities and subsequently are reimbursed by the entity the goods are being imported on behalf of. In other instances, however, the payment of VAT may be deferred and paid upon the sale of the goods to the ultimate end customer in cases where the entity receiving the goods holds a valid license allowing for the deferment of VAT (referred to as an Article 23 license). In the notification of assessment, the Dutch tax authorities have asserted that (i) we inappropriately deferred VAT for goods imported under Article 23 for certain of our customers between March 2017 and August 2018 and (ii) we are liable for the amount of VAT related to those goods for which VAT was inappropriately deferred. We have responded to the notification of assessment and have requested additional information regarding the matter from the Dutch tax authorities. We believe that the amount, if assessed, would be subject to interest and potential penalties. We have established a reserve for this matter based upon our estimate of the amount of loss that is both probable and estimable. We are in the process of exploring potential recoveries (including insurance recoveries and/or claims against other third parties) against any losses we incur associated with this matter.
