The decrease in the effective tax rate in the second quarter of 2013 compared to the second quarter of 2012 was primarily due to higher earnings in certain foreign jurisdictions where the effective tax rate is less than 35%, higher tax benefits from the U.S. research tax credit and lower losses at certain foreign subsidiaries where no tax benefit could be recorded. These factors were partially offset by a lower U.S. manufacturing deduction and certain discrete tax expenses.

The decrease in the effective tax rate in the first six months of 2013 compared to the first six months of 2012 was primarily due to higher earnings in certain foreign jurisdictions where the effective tax rate is less than 35%, higher tax benefits from the U.S. research tax credit and other discrete net income tax benefits. These factors were partially offset by U.S. state and local taxes and lower U.S. manufacturing deduction.
