Federal Income Taxes [Abstract]
Federal Income Taxes	17. Federal Income Taxes The effective tax rate is the ratio of tax expense (benefit) over pre-tax income (loss). The effective tax rate was 25% and 19% for the three months ended March 31, 2023 and 2022, respectively. The effective tax rate on pre-tax income is typically lower than the prevailing corporate federal income tax rate of 21% due to benefits from preferential tax items including the separate accounts dividends-received deduction and tax credits. For the three months ended March 31, 2023, the effective tax rate differed from the prevailing corporate federal income tax rate due primarily to a tax benefit at 21% from pre-tax losses in addition to the effects of preferential tax items. For the three months ended March 31, 2022, the effective tax rate differed from the prevailing corporate federal income tax rate due primarily to the effects of the preferential tax items.
