Income taxes for the three and six months ended June 30, 2011 includes the impact of a $10.5 million charge resulting from the enactment on May 25, 2011 of the Michigan Corporate Income Tax which eliminated certain future tax deductions.  Income taxes for the six months ended June 30, 2010 includes the impact of a $4.1 million charge resulting from health care reform legislation associated with the passage of the Patient Protection and Affordable Care Act and of the Health Care and Education Reconciliation Act of 2010 (the Acts).  The health care reform legislation enacted in March 2010 under the Acts eliminated the tax deduction for the subsidy that the Company receives under Medicare Part D for prescription drug costs.

The amount of our uncertain tax positions whose statute of limitations are expected to expire during the next twelve months and which would affect our effective tax rate is $17.4 million as of June 30, 2011.
