Income Taxes

NOTE 3—Income Taxes:

The effective income tax rate for the first quarter of 2012 was 25.5% compared with 24.2% for the first quarter of 2011. 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 2012 and 2011 periods is mainly due to the impact of earnings from outside the U.S.
