The Company had no provision for uncertain income tax positions at March 31, 2015 or December 31, 2014. The Company did not recognize any interest expense or other penalties related to U.S. federal or state income taxes during the three months ended March 31, 2015 or 2014. It is the Company’s accounting policy to reflect income tax penalties as other expense, and interest as interest expense.

The Company files a U.S. federal income tax return, along with various state income tax returns. The Company is no longer subject to U.S. federal and state income tax examinations by tax authorities for years before 2011. The Company’s 2011 income tax return has been audited and no adjustments were proposed.
