Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the three months ended June 30, 2019 and 2018, we recorded a provision for income taxes of $0.3 million on a pre-tax loss of $67.0 million for an effective tax rate of (0.4)%, and a provision for income taxes of $0.1 million on a pre-tax loss of $50.1 million for an effective tax rate of (0.3)%, respectively. For the six months ended June 30, 2019 and 2018, we recorded a provision for income taxes of $0.5 million on a pre-tax loss of $155.0 million for an effective tax rate of (0.3)%, and a provision for income taxes of $0.5 million on a pre-tax loss of $72.1 million for an effective tax rate of (0.6)%, respectively. The effective tax impact for the three and six months ended June 30, 2019 and 2018 is lower than the statutory federal tax rate primarily due to a full valuation allowance against U.S. deferred tax assets.
