Income Taxes

NOTE 3—Income Taxes:

The effective income tax rate for the first quarter of 2013 was 24.8% compared to 26.2% for the first quarter of 2012. The Company’s effective income tax rate fluctuates based on, among other factors, our level and location of income. The difference between the U.S. federal statutory income tax rate and our effective income tax rate for the 2013 and 2012 periods is mainly due to the impact of earnings from outside the U.S.
