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 minor exceptions, we are no longer subject to income tax examinations by any of the taxing jurisdictions for years before 2012. We currently have one foreign income tax examination in process. As of June 30, 2017 and December 31, 2016, unrecognized tax benefits related to federal, state and foreign jurisdictions were $0.7 million and $0.6 million, respectively, all of which may impact our effective tax rate, if recognized. The unrecognized tax benefits are netted against their related noncurrent deferred tax assets that are carried forward as net operating losses and tax credits. When appropriate, we accrue penalties and interest related to unrecognized tax benefits through income tax expense. Included in the unrecognized tax benefits is $0.2 million interest and penalties as of June 30, 2017 and December 31, 2016. During the six months ended June 30, 2017, there was no material change to our tax reserves. Events 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 June 30, 2017, due to cumulative losses and other factors, we continue to carry valuation allowances against the deferred assets primarily in the United Kingdom and Luxembourg. Additionally, we continue to carry valuation allowances related to certain state deferred assets that we believe to be 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. During the six months ended June 30, 2017, we recognized income tax benefit of $0.6 million relating to the write-off of deferred financing fees associated with the redemption of our 7.875% notes, as discussed in Note 11.
