Income Tax Disclosure [Abstract]
Income Taxes	9. Income Taxes. Our overall effective tax rate for the three months ended September 30, 2019 and 2018 was 40.3% and 14.3%, respectively, which resulted in income tax expense (benefit) of approximately $(2.3) million and $2.8 million, respectively. Our overall effective tax rate for the nine months ended September 30, 2019 and 2018 was 4.9% and 12.0%, respectively, which resulted in a provision for income taxes of approximately $0.5 million and $4.5 million, respectively. The income tax benefit and corresponding increase in the effective tax rate for the three-month period ended September 30, 2019, when compared to the prior-year period, was primarily due to a pre-tax loss during the period, as well as a change in the jurisdictional mix of earnings. The decrease in the effective tax rate for the nine-month period ended September 30, 2019, when compared to the prior-year period, was primarily the result of discrete items in the current-year period, which generated a greater tax benefit due to lower pre-tax income.
