Income Tax Disclosure [Abstract]  
Income Taxes Income TaxesIncome tax expense during interim periods is based on our estimated annual effective income tax rate plus any discrete items that are recorded in the period in which they occur. Our tax rate is affected by discrete items that may occur in any given year, but may not be consistent from year to year. Our effective tax rate was 22.2% and 46.7% for three months ended March 31, 2021 and 2020, respectively. The difference in the effective tax rate for the three months ended March 31, 2021 compared to the same period of prior year primarily results from 1) a full valuation allowance established in 2020 to offset the capital loss benefit in connection with our sale of Prime Turbines due to a lack of anticipated capital gain income in the carryforward period, 2) higher estimated Foreign Derived Intangible Income ("FDII") deduction in 2021, and 3) a favorable deduction in 2021 in connection with the fair value increase in our COLI assets..
