Income Taxes	Note 14 – Income Taxes Our effective income tax rate was 14.2% and 15.4% for the three months ended March 31, 2019 and 2018, respectively. The decrease from the first quarter of 2018 was primarily due to the beneficial impact of the international tax provisions from U.S. tax reform as a result of administrative guidance issued during 2018, excess tax deductions on equity compensation and a lower tax impact on unremitted foreign earnings and profits, partially offset by a one-time impact from R&D credits and a decrease in current quarter reversals of uncertain tax positions.

The total amount of unrecognized tax benefits as of March 31, 2019 was $9.2 million, of which $8.9 million would affect our effective tax rate if recognized.
