Income Tax Provision

(6) Income Tax Provision

For the three months ended March 31, 2012, we had an effective income tax rate of 39.2% compared to 39.6% for the three months ended March 31, 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 $1.4 million in the three months ended March 31, 2012, compared to $174,000 in net payments for the same period of the prior year.
