Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The provision for income taxes is based upon the estimated annual effective tax rates for the year applied to the current period income (loss) before tax plus the tax effect of any significant unusual items, discrete events or changes in tax law. Our operating subsidiaries are exposed to statutory effective tax rates ranging from zero to approximately 40%. Fluctuations in the distribution of pre-tax income (loss) among our operating subsidiaries can lead to fluctuations of the effective tax rate in the consolidated financial statements. For the three and nine months ended September 30, 2017, the actual effective tax rates were (3.1)% and (2.1)%, respectively. For the three and nine months ended September 30, 2016, the actual effective tax rates were 25.4% and 20.3%, respectively. We assess uncertain tax positions in accordance with ASC 740-10, Accounting for Uncertainties in Tax. As of September 30, 2017, our net unrecognized tax benefits totaled $0.5 million of which the entire portion would impact our effective tax rate if recognized. We anticipate that the amount of reasonably possible unrecognized tax benefits that could decrease over the next 12 months due to the expiration of certain statutes of limitations and settlement of tax audits is not material to our consolidated financial statements. We file income tax returns in the United States federal jurisdiction and in many state and foreign jurisdictions. The tax years 2013 through 2016 remain open to examination by the major taxing jurisdictions to which we are subject. No material examinations are currently open.

Income Taxes

The provision for income taxes is based upon the estimated annual effective tax rates for the year applied to the current period income (loss) before tax plus the tax effect of any significant unusual items, discrete events or changes in tax law. Our operating subsidiaries are exposed to statutory effective tax rates ranging from zero to approximately 40%. Fluctuations in the distribution of pre-tax income (loss) among our operating subsidiaries can lead to fluctuations of the effective tax rate in the consolidated financial statements. For the three and nine months ended September 30, 2017, the actual effective tax rates were (3.1)% and (2.1)%, respectively. For the three and nine months ended September 30, 2016, the actual effective tax rates were 25.4% and 20.3%, respectively.

We assess uncertain tax positions in accordance with ASC 740-10, Accounting for Uncertainties in Tax. As of September 30, 2017, our net unrecognized tax benefits totaled $0.5 million of which the entire portion would impact our effective tax rate if recognized. We anticipate that the amount of reasonably possible unrecognized tax benefits that could decrease over the next 12 months due to the expiration of certain statutes of limitations and settlement of tax audits is not material to our consolidated financial statements.

We file income tax returns in the United States federal jurisdiction and in many state and foreign jurisdictions. The tax years 2013 through 2016 remain open to examination by the major taxing jurisdictions to which we are subject. No material examinations are currently open.
