The effective tax rates for the three months ended March 31, 2017 and 2016 were 30.5% and 31.1%. The decrease in the effective tax rate during the three months ended March 31, 2017 was primarily due to an increase in the reserve for unrecognized tax benefits that occurred in 2016 but did not repeat in 2017 and the tax benefit recognized on share-based compensation in 2017. These favorable items were partially offset by a reduction of the tax benefit from the domestic manufacturer’s deduction that resulted from the contribution to the Plan as described above and an unfavorable geographic mix of pretax income. The effective tax rates for the six months ended March 31, 2017 and 2016 were 27.9% and 30.3%. The decrease in the effective tax rate during the six months ended March 31, 2017 was primarily due to the tax benefit recognized on share-based compensation in 2017 and an increase in the reserve for unrecognized tax benefits that occurred in 2016 but did not repeat in 2017. These favorable items were partially offset by a reduction of the tax benefit from the domestic manufacturer’s deduction that resulted from the funding of our U.S. defined benefit pension plan.
