10. Income Taxes

Income tax expense totaled $22.7 million, or an effective tax rate of 32.9%, for the three months ended March 31, 2016, compared to an income tax expense of $21.4 million, or an effective tax rate of 37.3%, for the same period in 2015. The effective tax rate includes the impact of the utilization of low income housing tax credits and the utilization of alternative energy tax credits.

As of December 31, 2015, the Company had income tax refunds receivable of $28.9 million. These income tax receivables are included in other assets in the accompanying condensed consolidated balance sheets.

The Company’s tax returns are open for audit by the Internal Revenue Service back to 2012 and by the California Franchise Tax Board back to 2008. As the Company is presently under audit by a number of tax authorities, it is reasonably possible that unrecognized tax benefits could change significantly over the next twelve months. The Company does not expect that any such changes would have a material impact on its annual effective tax rate.
