Income Tax Disclosure [Abstract] |
Income Taxes | 13. Income Taxes Recent appellate court decisions have required us to remeasure certain of our uncertain tax positions. Consequently, we increased our unrecognized tax benefit for these positions during the nine months ended September 30, 2017. We had $21.1 million and $9.7 million of unrecognized tax benefits at September 30, 2017 and December 31, 2016, respectively, of which $16.0 million and $9.7 million, respectively, would affect the effective tax rate if recognized. We also recorded $1.5 million and $0.2 million of potential interest expense and penalties related to unrecognized tax benefits associated with uncertain tax positions as of September 30, 2017 and December 31, 2016, respectively. In addition, our income tax provision reflects a federal benefit of $0.1 million and $2.4 million in the three and nine months ended September 30, 2017, respectively, and a deferred state release of $4.3 million in the nine months ended September 30, 2017 related to the increase in our unrecognized tax benefit.
