Income Taxes	(12) Income Taxes *Effective Income Tax Rate and Income Tax Provision* Our effective income tax rate was 26.4% for the three months ended September 30, 2011 and 27.5% for the same period in 2010. Our effective income tax rate was 27.1% for the nine months ended September 30, 2011 and 28.0% for the same period in 2010. For the three and nine months ended September 30, 2011 and 2010, our effective income tax rate was lower than the statutory U.S. federal income tax rate of 35% primarily due to our lower net effective income tax rate on foreign earnings and our domestic manufacturing deduction, partially offset by state income taxes. The rate for the three and nine months ended September 30, 2011 was also reduced by certain U.S. tax credits that were not available for the three and nine months ended September 30, 2010. *Unrecognized Tax Benefits* There have been no material changes to the Company’s unrecognized tax benefits as reported at September 30, 2011, nor have we changed our policy with regard to the reporting of penalties and interest related to unrecognized tax benefits.

Effective Income Tax Rate and Income Tax Provision

Our effective income tax rate was 26.4% for the three months ended September 30, 2011 and 27.5% for the same period in 2010. Our effective income tax rate was 27.1% for the nine months ended September 30, 2011 and 28.0% for the same period in 2010.

For the three and nine months ended September 30, 2011 and 2010, our effective income tax rate was lower than the statutory U.S. federal income tax rate of 35% primarily due to our lower net effective income tax rate on foreign earnings and our domestic manufacturing deduction, partially offset by state income taxes. The rate for the three and nine months ended September 30, 2011 was also reduced by certain U.S. tax credits that were not available for the three and nine months ended September 30, 2010.

Unrecognized Tax Benefits

Therefore, a reconciliation of unrecognized tax benefits from January 1, 2011 through September 30, 2011 has not been provided.
