12. 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 three months ended March 31, 2017. We had $19.6 million and $9.7 million of unrecognized tax benefits at March 31, 2017 and December 31, 2016, respectively, of which $15.3 million and $9.7 million, respectively, would affect the effective tax rate if recognized. We also recorded $1.0 million and $0.2 million of potential interest expense and penalties related to unrecognized tax benefits associated with uncertain tax positions as of March 31, 2017 and December 31, 2016, respectively. In addition, our income tax provision reflects a federal benefit of $1.8 million and a deferred state release of $4.3 million related to the increase in our unrecognized tax benefit.
