Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company maintains a valuation allowance for substantially all of its deferred tax assets. A valuation allowance is established or maintained when it is “more likely than not” that all or a portion of deferred tax assets will not be realized. The Company will continue to record a valuation allowance for the substantial majority of its deferred tax assets until there is sufficient evidence to warrant reversal. The tax provision for the nine months ended September 30, 2019 has been calculated using the Company’s overall estimated annual effective tax rate based on projected 2019 full year results. The Company’s effective tax rates for the three months ended September 30, 2019 and 2018 were 822.1% and (38.6)%, respectively. The Company’s effective tax rates for the nine months ended September 30, 2019 and 2018 were (31.7)% and (6.9)%, respectively. The Company’s effective tax rates for the three and nine months ended September 30, 2019 and 2018 were negatively impacted by the change in valuation allowance related to U.S. operating losses for which the Company cannot currently recognize a tax benefit. The Company’s income tax expense for the nine months ended September 30, 2019 of $7.9 million primarily relates to results from the Company’s non-U.S. businesses. As of September 30, 2019, the Company has approximately $0.4 million of unrecognized tax benefits and does not expect to recognize significant increases in unrecognized tax benefits during the next twelve-month period.
