Income Taxes	11. INCOME TAXES The effective income tax rate was 36.3% for the three months ended September 30, 2011 compared to 36.8% for the three months ended September 30, 2010. For the nine months ended September 30, 2011, the effective tax rate was 36.5% compared to 37.0% for the nine months ended September 30, 2010. The higher tax rate for the nine months ended September 30, 2010 primarily was due to the cumulative adjustment associated with estimating the retrospective aspect of new limitations on the deductibility of annual compensation in excess of $500,000 per employee as mandated by the Health Insurance Reform Legislation.
