INCOME TAXES
The effective income tax rate for the third quarter of 2011 was 15.2% compared to 11.7% for the third quarter of 2010 and 14.8% for the first nine months of 2011 compared to 12.0% for the first nine months of 2010. Higher effective tax rates in both the third quarter and first nine months of 2011 were primarily attributable to greater levels of income in high tax jurisdictions, particularly in the United States and Brazil, due to improved economic and market conditions.
