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 any of the taxing jurisdictions for years before 2011. We currently have two income tax examinations in process. As of June 30, 2016, we had $0.5 million of unrecognized tax benefits related to federal, state and foreign jurisdictions, all of which impact our effective tax rate, if accrued. 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, 2016. During the six months ended June 30, 2016, we did not release any tax reserves associated with items falling outside the statute of limitations and the closure of certain tax years for examination purposes. 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 June 30, 2016, due to cumulative losses and other factors, we continued to carry valuation allowances against the deferred assets primarily in the following foreign jurisdictions: United Kingdom, China, India 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.
