Income Taxes [Abstract]
Income Taxes	(14) Income Taxes The tax years 2008 through 2011 remain open to examination by the major taxing jurisdictions to which the Company is subject. Audits of the Company’s 2008 and 2009 U.S. federal income tax returns are in process as of March 31, 2012. To date, no material issues have been raised. Due to the potential for resolution of the examination or expiration of statutes of limitations, it is reasonably possible that the Company’s gross unrecognized tax benefits may change within the next 12 months by a range of zero to $861. The Company received its 2010 federal tax refund of $2,025 during February 2012 and its 2009 federal income tax refund of $6,344 during January 2011.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
