Federal Income Taxes [Abstract]
Federal Income Taxes	7. Federal Income Taxes The effective tax rate is a ratio of tax expense over pre-tax income (loss). The effective tax rate was 24% and 23% for the three and nine months ended September 30, 2013, respectively. The effective tax rate was 4% and 17% for the three and nine months ended September 30, 2012, respectively. The effective tax rate on pre-tax income from continuing operations was lower than the prevailing corporate U.S. federal income statutory rate of 35% as a result of certain tax preferred investment income, separate account dividends-received deduction, foreign tax credits and other tax preference items. A benefit to the effective tax rate was recognized in 2012 from a release of liability for uncertain tax positions related to the lapse of statute of limitations for prior year tax returns.

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.
