Income Tax Disclosure [Abstract]  
INCOME TAXES INCOME TAXES The effective income tax rates for the three months ended March 31, 2021 and 2020 were 19.3% and 28.7%, respectively. The period-over-period decrease in the effective income tax rates is due to the effect of rate-regulated accounting for income taxes and the benefit of foreign tax rate differentials relative to the change in earnings.
