Income Taxes

The Company records income tax expense or benefit each quarter based on its estimated full-year effective tax rate. Income tax expense of $309 and income tax benefit of $16 were recognized in the three months ended March 31, 2015 and March 31, 2014, respectively. Tax expense in the first quarter of 2015 includes $427 of adjustments related to temporary differences. The Company agreed to these adjustments as a result of an ongoing audit by the IRS related to the 2012 and 2013 tax years. The impact of these adjustments was offset by a current tax benefit of $118. The Company continues to carry a full valuation allowance on its net deferred tax assets, which totaled $12,676 at both March 31, 2015 and December 31, 2014.
