INCOME TAXES INCOME TAXES
The effective income tax rates for the three months ended September 30, 2020 and 2019 were 17.3% and 19.4%, respectively and for the nine months ended September 30, 2020 and 2019 were 15.3% and 20.6%, respectively.

The period-over-period change in the effective income tax rates is due to the effect of rate-regulated accounting for income taxes and the benefit of foreign rate differentials being partially offset by higher United States minimum tax relative to the change in earnings period-over-period.
