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 18.8% and 23.4% for the three and nine months ended September 30, 2021, respectively, and 23.9% and (38.4)% for the three and nine months ended September 30, 2020, respectively. The difference in the effective tax rate for the three and nine months ended September 30, 2021 compared to the same period of prior year primarily results from 1) a significantly higher tax loss than book loss in connection with our sale of Prime Turbines stock and a full valuation allowance established in 2020 to offset the capital loss benefit due to a lack of anticipated capital gain income in the carryforward period, 2) goodwill impairment loss recognized in 2020 that was not deductible for tax purposes, and 3) book loss in 2020 compared to book income in the same period in 2021. The tax rate for the current year benefited from tax deductions for foreign derived intangible income ("FDII") and COLI income, and various federal and state income tax incentives.
