For each of the three months ended March 31, 2013 and 2012, the Company's effective tax rate, excluding income attributable to the noncontrolling interest, was 37 percent. The Company's effective tax rate differed from the U.S. statutory rate of 35 percent due to state income taxes and nondeductible expenses.

The Company files income tax returns in the U.S. federal and various state and foreign jurisdictions. The Internal Revenue Service has closed examinations of the 2011 and prior tax years and, with few exceptions, the Company believes that it is no longer subject to examinations by state and foreign tax authorities for years before 2008. As of March 31, 2013, no adjustments had been proposed in any jurisdiction that would have a significant effect on the Company's liquidity, future results of operations or financial position.
