10.                Income Taxes

The following table includes income tax provision and the effective tax rate for the Company’s income from operations:

The Company’s effective tax rate in the three and nine months ended September 30, 2013, was lower than the effective tax rate in the three and nine months ended September 30, 2012, primarily due to the effect of research and development tax credits.

The liability for unrecognized tax benefits reported in other non-current liabilities was $2,625 and $1,739 at September 30, 2013 and December 31, 2012, respectively. At September 30, 2013, the amount of unrecognized tax benefits that would benefit the Company’s effective tax rate, if recognized, was $1,785. At this time, the Company estimates it is reasonably possible that the liability for unrecognized tax benefits will decrease by as much as $261 in the next twelve months due to the completion of reviews by tax authorities, the voluntary filing of certain state income tax returns and the expiration of certain statutes of limitations.

The Company recognizes potential interest and penalties related to unrecognized tax benefits in income tax expense. The Company had accrued interest and penalties of $661 and $642 as of September 30, 2013 and December 31, 2012, respectively.

The Company files a consolidated federal income tax return and separate tax returns with various states. Additionally, a subsidiary of the Company files a tax return in a foreign jurisdiction. The Company’s tax returns for the calendar years ended December 31, 2012, 2011 and 2010 remain open to examination by the Internal Revenue Service in their entirety. With respect to state taxing jurisdictions, the Company’s tax returns for calendar years ended December 31, 2012, 2011 and 2010 remain open to examination by various state revenue services.

The Company’s India subsidiary is currently under examination by the India Taxing Authority for the fiscal years ended March 31, 2009 and March 31, 2010. Based on the outcome of examinations of the Company’s subsidiary or the result of the expiration of statutes of limitations, it is reasonably possible that the related unrecognized tax benefits could change from those recorded in the condensed consolidated balance sheets. It is possible that one or more of these audits may be finalized within the next twelve months. The Company’s subsidiary’s tax returns for the fiscal years ended March 31, 2007 through March 31, 2012 remain open to examination by the India Taxing Authority in their entirety.
