8.	Income Taxes

The effective income tax rates for continuing operations for the quarters ended June 30, 2017 and 2016, were 22.4% and 36.6%, respectively. For the six-month periods ended June 30, 2017 and 2016, the effective income tax rates for continuing operations were 25.3% and 31.6%, respectively. The effective tax rates in both 2017 and 2016 were impacted by restructuring activities, changes in estimates associated with the finalization of prior year foreign and domestic tax items, audit settlements, adjustments to valuation allowances, and mix of foreign earnings. The tax rate for the three-month period ended June 30, 2017, was also impacted by a tax planning opportunity that expires in 2017. The six-month period ended June 30, 2017, was also impacted by the limited tax deductibility of losses related to the divestitures discussed in Note 11, Restructuring and Note 13, Divestiture.
