Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We file federal and state income tax returns in the U.S. and income tax returns in foreign jurisdictions. With a few exceptions, we are no longer subject to income tax examinations by the taxing jurisdictions for years prior to 2014. As of March 31, 2018 and December 31, 2017, the Company had $0.5 million in unrecognized tax benefits related to U.S. federal, state and foreign jurisdictions which may impact our effective tax rate, if recognized. The domestic unrecognized tax benefits are netted against their related long-term deferred tax assets. We accrue penalties and interest related to unrecognized tax benefits through income tax expense. Included in the unrecognized tax benefits is $0.3 million of interest and penalties as of March 31, 2018 and December 31, 2017. We are not aware of any events that could occur within the next twelve months that would have an impact on the amount of unrecognized tax benefits that would require a reserve. At March 31, 2018, due to cumulative losses and other factors, we continue to carry valuation allowances against the deferred tax assets, primarily in the United Kingdom and Luxembourg. Additionally, we continue to carry valuation allowances related to certain state deferred tax assets that we believe are more likely than not to expire before they can be utilized. We evaluate the need for valuation allowances in each of our jurisdictions on a quarterly basis. The enactment of U.S. Tax Reform brought about significant changes to the U.S. tax code, including implementing a new provision designed to tax global intangible low-taxed income (“GILTI”) of foreign subsidiaries but allowing for the possibility to utilize foreign tax credits to offset the associated tax liability (subject to certain limitations). Pursuant to SAB 118, the Company is allowed to make an accounting policy of either (1) treating taxes due on future U.S. taxable income inclusions related to GILTI as a current-period expense when incurred (the “period cost method”) or (2) factoring such amounts into the measurement of the Company’s deferred taxes (the “deferred method”). Although we included an estimate of the current period impact of GILTI in our tax provision for the period ended March 31, 2018, we are still in the process of evaluating and have not yet made a policy decision as to how the Company will account for the tax implications of GILTI in future periods. Under SAB 118, we have until December 31, 2018, to formalize our policy.
