Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The effective tax rate on earnings (loss) from Cont Ops was 38.4% for the 2021 Quarter and 97.8% for the 2021 Period compared to 52.6% and (5.3)% for the corresponding periods of 2020. For all periods, the effective tax rate was unfavorably impacted by increases in the valuation allowances against foreign tax credit carryforwards and certain foreign net operating loss carryforwards. The 2021 Period unfavorable impact was partially offset by favorable foreign tax rate differentials. The effective tax rate in the 2020 Period was favorably impacted by the release of valuation allowances and rate benefits resulting from the carryback of our 2019 federal net operating loss as allowed by the CARES Act. Earnings attributable to non-controlling interests from continuing operations, for which income taxes are not typically our responsibility, favorably impacted the effective tax rate for the 2021 Period.
