8 – Income Taxes

The Company included accruals for unrecognized income tax benefits totaling $1.4 million as a component of accrued liabilities as of March 31, 2013, and $1.3 million as of March 31, 2012.  Unrecognized tax benefits of $1.0 million at March 31, 2013, and $1.3 million as of March 31, 2012, if recognized, would impact the Company’s effective tax rate.  An unfavorable settlement could require a charge to income tax expense and a favorable resolution would be recognized as a reduction to income tax expense.  The Company records interest and penalties related to unrecognized income tax benefits in income tax expense.  The Company had accrued interest of $49,000 at March 31, 2013 and $51,000 at March 31, 2012 related to unrecognized tax benefits.  No amounts were accrued for penalties.

The Company does not anticipate a significant change in the amount of unrecognized tax benefits in the next 12 months.  As of March 31, 2013, the tax years ended December 31, 2009 through 2012 remained subject to audit by federal tax authorities and the tax years ended December 31, 2008 through 2012, remained subject to audit by state tax authorities.
