The effective rate for the three months ended December 31, 2016 increased compared to the prior year period primarily due to the impact of lower qualifying production activity deductions in the current period, certain non-deductible acquisition-related costs, and a discrete valuation allowance, offset by federal and state research and development credit and other discrete adjustments.
