Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The provision or benefit for income taxes for the periods presented differs from the 34% U.S. Federal statutory rate primarily due to maintaining a valuation allowance for U.S. losses and tax assets, which we do not consider to be realizable. We recorded a tax benefit of $1.0 million and $1.8 million for the three and six months ended June 30, 2016, respectively, which was primarily attributable to the amortization of our acquisition related deferred tax liability, partially offset by tax provision and discrete items from our foreign operations. We recorded a tax benefit of $0.3 million and $0.9 million for the three and six months ended June 30, 2015, respectively, which was primarily attributable to the amortization of our acquisition-related deferred tax liability, partially offset by tax provision and provision for uncertain tax liabilities related to our foreign operations.
