Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company applied an estimated annual effective tax rate (“ETR”) approach for calculating a tax provision for interim periods. The Company recorded a benefit for income taxes of $0.3 million and provision for income taxes of $0.2 million for the three months ended September 30, 2019 and 2018, respectively. The Company recorded a benefit for income taxes of $3.5 million and provision for income taxes of $0.3 million for the nine months ended September 30, 2019 and 2018, respectively. The Company’s ETR was (3.5)% and 1.7% for the three months ended September 30, 2019, and 2018, respectively. The Company’s ETR was (5.8)% and 0.5% for the nine months ended September 30, 2019, and 2018, respectively. The Company’s ETR for the three and nine months ended September 30, 2019 differs from the U.S. federal statutory tax rate of 21% primarily as a result of state income taxes, foreign income taxes, and the impact of a full valuation allowance on its deferred tax assets. In addition, the ETR for the three and nine months ended September 30, 2019 was impacted by the application of the exception to the tax intraperiod allocation rules as discussed below. The Company has evaluated the available evidence supporting the realization of its deferred tax assets, including the amount and timing of future taxable income, and has determined that it is more likely than not that the domestic and foreign deferred tax assets will not be realized. Due to such uncertainties surrounding the realization of the domestic and foreign deferred tax assets, the Company maintained a valuation allowance against a substantial portion of its deferred tax assets as of September 30, 2019. If and when the Company determines that it will be able to realize some portion or all of its deferred tax assets, an adjustment to its valuation allowance on its deferred tax assets would have the effect of increasing net income in the period(s) such determination is made. The exchange of 3.25% convertible notes for new 5.00% convertible notes in April 2019 resulted in an increase to the temporary difference between the carrying amount and tax basis of the convertible notes. The increase in the taxable temporary difference resulted in the recognition of a $4.9 million deferred tax liability (net of debt converted to equity in Q3), which was recorded as an offset to additional paid-in-capital. In accordance with ASC 740-20, Intraperiod Tax Allocation, the increase in the deferred tax liability provided an additional source of income to realize the benefit from the current year loss from continuing operations, which resulted in the recognition of a $0.3 million and $3.7 million income tax benefit during the three and nine months ended September 30, 2019, respectively. This income tax benefit is calculated based on the ratio of the Company’s year to date pre-tax losses compared to the forecasted annual pre-tax book losses for federal and state jurisdictions. The Company expects to recognize an additional $1.2 million of tax benefit during the three months ended December 31, 2019 to offset the $4.9 million tax expense recorded in additional paid-in capital during the second quarter.
