Income Taxes	7. Income Taxes Our effective income tax rates for the first quarter of 2017 and 2016 were 32.7% and 14.4%, 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 income tax provision by $17.6 million and our effective income tax rate by 16.1% in the first quarter of 2016. Other 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%.
