Income Taxes

The effective tax rates of 27.2% and 29.1% for the three and nine months ended June 30, 2012 and 25.9% and 27.4% for the three and nine months ended July 2, 2011 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.
