Income Taxes
Income Taxes	6.  Income Taxes Our effective income tax rates for the three-month periods ended June 30, 2012 and 2011 were 34.3% and 35.0%, respectively. Our effective income tax rates for the six-month periods ended June 30, 2012 and 2011 were 33.7% and 34.2%, respectively. Permanent items that lowered our effective income tax rates from the federal statutory rate were not materially different in amounts during these periods and relate mainly to company-owned life insurance policies, domestic production activities deductions and foreign income levels that are taxed at lower rates.
