The Company files income tax returns in the U.S. Federal jurisdiction and various state jurisdictions. With few exceptions, the Company is no longer subject to U.S. Federal or state income tax examinations by tax authorities for years before 2007. The Company believes it is not subject to any significant tax risk.  The Company does not have any accrued interest or penalties associated with any unrecognized tax benefits, nor were any interest expenses recognized during the six months ended June 30, 2011 or June 30, 2010.
 
As a result of the Patient Protection and Affordable Care Act, as modified by the Health Care and Education Reconciliation Act of 2010,  we will no longer be able to claim an income tax deduction related to prescription drug benefits provided to retirees and reimbursed under the Medicare Part D retiree drug subsidy beginning in 2013. This resulted in a $685,000 charge to income tax provision during the first quarter of 2010.
