NOTE G – Income Taxes

The effective income tax rate in the first quarter of 2013 of 30.0% decreased from 31.7% in the first quarter of 2012. The decrease in the current quarter effective tax rate was primarily due to the impact of U.S. tax law changes enacted on January 2, 2013 that had a retroactive effect to January 1, 2012 for research and development and undistributed foreign finance income.
