Income Taxes	7. Income Taxes Our effective income tax rates for the first quarter of 2016 and 2015 were 14.4% and 31.7%, respectively. During the first quarter of 2016, favorable developments occurred toward the resolution of a tax position that was previously uncertain. The re-measurement of that tax position lowered our effective tax rate by 16.1% in the first quarter of 2016, which is not expected to occur in subsequent periods. 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%.
