As of December 31, 2011 and 2012, the Company does not have any material unrecognized tax benefits and accordingly has not recorded any interest or penalties related to unrecognized tax benefits. The Company and its subsidiaries file a consolidated federal income tax return and various state returns. These returns remain subject to examination by taxing authorities for all years after 2008.
