10.	Income Taxes

The provision for income taxes for the three months and nine months ended September 30, 2011 reflects an estimated annual effective tax rate of 25 percent compared to 24 percent for the first nine months of 2010 and 19 percent for the full year of 2010. The increase from the full-year 2010 effective tax rate is primarily due to expected changes in the geographic mix of pre-tax profits and the absence of $22 million of benefits included in the 2010 full-year effective tax rate related to prior years. The 2011 estimated annual effective tax rate is expected to be less than the U.S. corporate tax rate of 35 percent primarily due to profits in tax jurisdictions with lower tax rates.
