INCOME TAXES
The effective income tax rate for the second quarter of 2011 was 14.7% compared to 9.0% for the second quarter of 2010 and 14.6% for the first six months of 2011 compared to 12.2% for the first six months of 2010. Higher effective tax rates in both the second quarter and first six months of 2011 were primarily attributable to greater levels of income in high tax jurisdictions, particularly in the United States, due to improved economic conditions.
