Note 12—Income Taxes

The effective tax rate was 16.5% and 17.2% for the three months ended March 31, 2019 and 2018, respectively. The change in the effective tax rate for the three months ended March 31, 2019 was primarily due to the increased recognition of windfall tax benefits from stock awards in the current year, partially offset by a proportionate change in the composition of income before income taxes from foreign and domestic tax jurisdictions.
