Income Tax Disclosure [Abstract]
Income taxes	Note 19. Income taxes Our consolidated effective income tax rate for the first quarter was 21.2% in 2020 and 21.4% in 2019. Our effective income tax rate normally reflects recurring benefits from dividends-received deductions applicable to investments in equity securities and production tax credits related to wind-powered electricity generation placed in service in the U.S. Our periodic effective income tax rate will also vary due to the changes in mix of pre-tax earnings, the magnitude of gains or losses included in earnings with respect to our investments in equity securities, and underlying income tax rates applicable in the various taxing jurisdictions.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
