        The difference between the U.S. federal statutory tax rate of 35% and the Company's effective tax rates for the three and six months ended June 30, 2011 and 2010 was principally due to state income taxes.

        The Company had approximately $0.6 million of total unrecognized tax benefits as of June 30, 2011 and December 31, 2010, which was included in other liabilities in the accompanying consolidated balance sheets.

        The Company's policy is to recognize interest and penalties related to income tax liabilities as a component of income tax expense in the consolidated statements of operations. The amount of interest and penalties charged to income tax expense as a result of the unrecognized tax benefits was a benefit of less than $0.1 million for both of the six-month periods ended June 30, 2011 and 2010.

        The Company is subject to taxation in various jurisdictions. The Company continues to remain subject to examination by U.S. federal authorities for certain open tax years (2009 and 2010), and by various state authorities for the years 2006 through 2010.
