Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES For the three and six months ended June 30, 2019, we recorded an income tax benefit of $0.4 million and $0.3 million, respectively, compared with income tax expense of $0.3 million and $0.4 million for the three and six months ended June 30, 2018, respectively. Our effective tax rate was (6.1%) for the three months ended June 30, 2019 compared with 19.9% in the prior year period. Our effective tax rate was (4.0%) for the six months ended June 30, 2019 compared with 20.5% in the prior year period. The change in our income tax (benefit) expense was primarily due to a pretax loss during the three and six months ended June 30, 2019 compared to pretax income in the same periods of 2018, partially offset by a $0.9 million increase in our reserve for uncertain tax positions recorded during the three months ended June 30, 2019 due to a change in our judgment on the recognition of a tax position during the quarter. Our quarterly estimate of our annual effective tax rate, and our quarterly provision for income tax (benefit) expense, are subject to significant variation due to numerous factors, including variability in accurately predicting our pretax and taxable income or loss and the mix of jurisdictions to which they relate, as well as the amount of pretax income or loss recognized during the quarter.
