Income Taxes
The Company's effective income tax rate was 37.0% for the three months ended March 31, 2014 and differed from the U.S. federal statutory rate primarily due to state income taxes. For the three months ended March 31, 2013, the effective income tax rate was 36.4% and differed from the U.S. federal statutory rate primarily due to state income taxes.
In the ordinary course of business, the Company is subject to review by domestic and foreign taxing authorities, including the Internal Revenue Service (the “IRS”). In general, the Company is no longer subject to audit by the IRS for tax years through 2010 and state, local or foreign taxing authorities for tax years through 2008. Various other taxing authorities are in the process of auditing income tax returns of the Company and its subsidiaries. The Company does not anticipate that any adjustments from the audits would have a material impact on its consolidated financial position, results of operations or cash flows.
