Income Taxes
Income Taxes	7.  Income Taxes Our effective income tax rates for the three-month periods ended June 30, 2016 and 2015 were 32.7% and 32.6%, respectively. Our effective income tax rates for the six-month periods ended June 30, 2016 and 2015 were 25.0% and 32.1%, respectively. Our 2016 six-month period effective income tax rate was favorably impacted by the resolution of a tax position that was previously uncertain, which lowered our 2016 six-month effective income tax rate by 6.7%. Permanent items that lowered our effective income tax rates from the federal statutory rate were not materially different during both years and relate mainly to company-owned life insurance policies, domestic production activities deductions and foreign income levels that are taxed at rates lower than the U.S. statutory rate of 35%.
