NOTE 9 - INCOME TAXES
The provision for income taxes was $146 million and $91 million for the three months ended June 30, 2013 and 2012, respectively, representing effective tax rates of 28% and 25%, respectively. For the six months ended June 30, 2013 and 2012, the provision for income taxes was $297 million and $160 million, respectively, representing effective tax rates of 29% and 23%, respectively. The Company calculated the provision for income taxes for the three and six months ended June 30, 2013, by applying the estimated annual effective tax rate to year-to-date pre-tax income. For the three and six months ended June 30, 2012, the provision for income taxes was calculated discretely based on actual year-to-date results. Interest and penalties related to tax matters are recorded as a component of the income tax provision.
