At December 31, 2014, the Company had approximately $35.28 million in state net operating loss carry forwards that expire from 2014 through 2034. The Company has a valuation allowance of $409,000 associated with U.S. state net operating losses. The valuation allowance increased by $409,000 due to uncertainty regarding the ability to utilize the losses.


The Company had unrecognized income tax benefits totaling $1.5 million as a component of accrued liabilities at December 31, 2014, and $1.0 million at December 31, 2013, the total of which, if recognized, would impact the Company’s effective tax rate. An unfavorable settlement would require a charge to income tax expense and a favorable resolution would be recognized as a reduction to income tax expense. The Company recognizes interest accrued related to unrecognized tax benefits in income tax expense. During the years ended December 31, 2014, 2013 and 2012, the Company recognized approximately $17,500, $32,000, and $2,300 in interest. No amounts were accrued for penalties. The Company had approximately $98,500, $81,000 and $49,000 for the payment of interest accrued at December 31, 2014, 2013 and 2012, respectively.


The Company does not anticipate a significant change in the amount of unrecognized tax benefits in the next 12 months. As of December 31, 2014, the tax years ended December 31, 2011 through 2014 remained subject to audit by federal tax authorities and the tax years ended December 31, 2010 through 2014, remained subject to audit by state tax authorities.
