10.Income Taxes

The following table includes the Company’s income before income tax provision, income tax provision and effective tax rate:

The Company’s effective tax rate in the three months ended March 31, 2015, was higher than the effective tax rate in the three months ended March 31, 2014, primarily due to the increase in tax rate for federal purposes from 34% to 35%, the true-up on India unremitted earnings that was recorded in the three months ended March 31, 2014 and not in the same period in 2015, and the release of certain uncertain tax position reserves in the three months ended March 31, 2014 that were not repeated in the same period in 2015.

The liability for unrecognized tax benefits reported in other non-current liabilities was $2,081 and $2,092 at March 31, 2015 and December 31, 2014, respectively. At March 31, 2015, the amount of unrecognized tax benefits that would benefit the Company’s effective tax rate, if recognized, was $1,962. At this time, the Company estimates it is reasonably possible that the liability for unrecognized tax benefits will decrease by as much as $1,217 in the next twelve months due to the completion of reviews by tax authorities, the voluntary filing of certain state income taxes 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 $568 and $594 as of March 31, 2015 and December 31, 2014, respectively.

The Company files a consolidated federal income tax return and separate tax returns with various states. Additionally, foreign subsidiaries of the Company file tax returns in foreign jurisdictions. The Company’s tax returns for the calendar years ended December 31, 2013, 2012, and 2011 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, 2013, 2012, 2011, 2010 and 2009 remain open to examination by various state revenue services.

The Company’s Indian subsidiary is currently under examination by the India Tax Authority for the fiscal year ended March 31, 2009, 2011 and 2012. It is possible that one or more of these audits may be finalized within the next twelve months.

Included in prepaid expenses and other current assets on the condensed consolidated balance sheet as of March 31, 2015 is $13,355 primarily related to excess tax benefits from stock-based compensation.
