        The difference between the U.S. federal statutory tax rate of 35% and the Company's effective tax rates for the three and nine months ended September 30, 2012 and 2011 was principally due to state income taxes.

        The Company is subject to taxation in various jurisdictions. The Company's federal tax returns for 2010 and 2009 are currently under examination by the Internal Revenue Service. The Company's tax returns continue to remain subject to examination by the Internal Revenue Service for 2011 and by various state authorities for the years 2008 through 2011.
