Income Taxes

The effective tax rates for the three months ended December 29, 2012 and December 31, 2011 of 30.5% and 31.3%, respectively, are lower than would be expected by applying the U.S. federal statutory tax rate to earnings before income taxes primarily as a result of a significant portion of our earnings that come from foreign operations with lower tax rates.
