Income Taxes

13. Income Taxes – Income tax expense for the three and six months ended June 30, 2012 of $86.6 million and $162.2 million was recorded, representing an effective tax rate of 32.5% and 32.3%, respectively. The prior year three and six month provisions for income tax were $77.5 million and $156.5 million, representing effective tax rates of 33.8% and 34.1%, respectively. The prior year periods’ effective tax rates were higher primarily due to certain restructuring, acquisition, and integration related expenses attributable to lower tax rate jurisdictions. The prior year six month period also included adjustments to deferred tax reserves as a result of an Illinois corporate income tax rate increase enacted in January 2011.
