INCOME TAXES	NOTE 11—INCOME TAXES The effective tax rate was 30.3 percent and 29.7 percent for the second quarter and first six months of 2011, respectively, and 29.9 percent and 32.8 percent for the second quarter and the first six months of 2010, respectively. The decrease in the effective tax rate for the first six months of 2011 compared to 2010 was primarily due to the impact of an $11.4 million Federal and State income tax charge in the first six months of 2010 related to the Patient Protection and Affordable Care Act and the Health Care and Education Reconciliation Act signed into law in March 2010. At December 31, 2010, the Company had $31.3 million in unrecognized tax benefits, the recognition of which would have an effect of $27.4 million on the current provision for income taxes. Included in the balance of unrecognized tax benefits at December 31, 2010, was $6.0 million related to tax positions for which it is reasonably possible that the total amounts could significantly change during the next twelve months. This amount represents a decrease in unrecognized tax benefits comprised of items related to assessed state income tax audits, state settlement negotiations currently in progress and expiring statutes in foreign jurisdictions.

The IRS subsequently added the 2009 year to its audit for excise taxes. The IRS is auditing transactions related to the Company’s ESOP (the “Leveraged ESOP Transactions”).

The Company believes that the IRS’s proposed adjustments are incorrect, intends to vigorously defend its positions and is examining various procedural alternatives for resolution of this matter. Given the nature of these procedures, the Company is unable to predict with certainty the ultimate outcome or whether it will be required to make material payments of tax, interest and penalties to the IRS. During the IRS’s examination of the transactions, it requested the Department of Labor to also review the transactions. Following the Department of Labor’s initial examination, it is coordinating its response with the IRS. The Company has retained counsel to assist with the audit process and to respond to any claims or assessments the IRS or Department of Labor issues. No accrual has been made for any contingency related to the Leveraged ESOP Transactions. As of June 30, 2011, the Company is subject to non-U.S. income tax examinations for the tax years of 2004 through 2010. In addition, the Company is subject to state and local income tax examinations for the tax years 2001 through 2010.
