The effective tax rate was 27.7% in the three months ended March 31, 2017 compared to 32.9% for the same period in 2016. Effective tax rates for these quarters differ from statutory federal income tax rates, due to the domestic manufacturing deduction, provisions for state and local income taxes and permanent tax differences. The decrease in the effective tax rate for the three months ended March 31, 2017 compared to the same period of 2016 is primarily due to favorable discrete items that impacted the Company's tax provision in the amount of $5.6 million, of which $3.8 million was related to a change in tax method and $1.8 million was related to the adoption of ASU 2016-09 during the most recently completed quarter, which requires prospective recognition of excess tax benefits and deficiencies from stock-based compensation arrangements in the income statement as a component of the income tax provision. The new ASU and its impacts on the Company's Consolidated Statements of Income and Statements of Cash Flows are further described in Note 2 of the Notes to the Consolidated Financial Statements in this Form 10-Q.
