Income Taxes

Our effective income tax rate for continuing operations for the three months ended March 31, 2014 was 10.5%, or an expense of $2.2 million, as compared to an effective tax rate of (1.2)%, or benefit of $1.1 million, for the corresponding prior-year period. Our tax rate differs from the statutory rate of 35.0% due to the effects of permanent items, deferred tax expense on tax amortization of indefinite-lived intangible assets, state taxes and a reserve for unrecognized tax benefits. Our state tax provision represents taxes in the jurisdiction of Indiana, Louisiana and the city jurisdictions of Missouri where we have no valuation allowance.
