Income Taxes

NOTE 3—Income Taxes:

The effective income tax rate for the three-month and six-month periods ended June 30, 2013 was 20.9% and 22.9%, respectively, compared to 34.9% and 28.8% for the three-month and six-month periods ended June 30, 2012, respectively. 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. Our effective income tax rate for the 2012 periods was also impacted by $94.7 million in pre-tax charges ($73.6 million after income taxes) associated with our exit of the phosphorus flame retardants business (see Note 13).
