INCOME TAXES INCOME TAXES

The effective income tax rates for the three months ended March 31, 2020 and 2019 were 28.7% and 22.4%, respectively. The period-over-period increase in the effective income tax rate is due to the benefit of rate-regulated accounting for income taxes being partially offset by higher United States minimum tax.
