Income Tax Provision

(6) Income Tax Provision

For the three and six months ended June 30, 2012, we had an effective income tax rate of 39.2% compared to 39.6% for the three and six months ended June 30, 2011.The effective income tax rates for the periods presented were different from the statutory United States federal income tax rate of 35% primarily due to state income taxes, non-deductible share-based compensation expense, the qualified manufacturing activities deduction, and non-deductible meals and entertainment costs.

We made federal and state income tax payments, net of refunds, of $8.4 million in the six months ended June 30, 2012, compared to $5.9 million in net payments for the same period of the prior year.
