Income Taxes INCOME TAXES
Our effective tax rates were 15.0% and 27.4% in the three months and 14.6% and 23.2% in the six months 2019 and 2018. The decrease in the effective tax rate for the three and six months was primarily due to a favorable United States audit settlement for tax years 2012 and 2013.
