Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company (“FGL Holdings, Cayman”) is a Cayman-domiciled corporation that has operations in Bermuda and the U.S. Neither the Cayman Islands nor Bermuda impose a corporate income tax. The Company’s U.S. non-life subsidiaries file a consolidated non-life U.S. Federal income tax return. For tax years prior to December 1, 2017, the non-life members were included in former parent company HRG’s consolidated U.S. Federal income tax return. The income tax liabilities of the Company as former members of the consolidated HRG return were calculated using the separate return method as prescribed in ASC 740. The Company’s US life insurance subsidiaries file a separate life consolidated U.S. Federal income tax return. The life insurance companies will be eligible to join in a consolidated filing with the U.S. non-life companies in 2022. The Company’s Bermuda insurance subsidiary, F&G Life Re Ltd., is party to a ModCo reinsurance agreement with its US Life sister company, FGL Insurance. The Tax Cut and Jobs Act (“TCJA”) enacted on December 22 2017, contained a Base-Erosion and Anti-Abuse Tax (“BEAT”). The BEAT provisions apply a minimum tax (5% in 2018) to certain reinsurance payments settled between FGL Insurance and F&G Life Re Ltd. Absent clarifying guidance, the current language in the Act suggests that the tax is applied without regard to deduction or offset under a typical ModCo reinsurance agreement (i.e. a “Gross application”). Without clarifying guidance from Regulatory authorities in regards to allowing for a “Net application” in the calculation of BEAT, the Company will make an election under IRC Code Section 953(d) for the 2018 tax year, which will result in F&G Re Ltd. being treated as if it were a US Tax Payer. The effect of the election would be retroactive to the beginning of the Tax calendar year. The current period financial statements reflect an assumed 953(d) election with regard to F&G Life Re Ltd. As a result of the assumed election, which would occur in the event that clarifying language allowing a "net application" is not determined, an opening balance sheet deferred tax liability was set up resulting in a discrete expense being recorded in the first quarter of 2018. The provision for income taxes represents federal income taxes. The effective tax rate for the three and nine months ended September 30, 2018 was 21% and 29%, respectively. The effective tax rate for the three and nine months ended September 30, 2017 was 30% and 32%, respectively. The effective tax rate on pre-tax income for the current nine months ended September 30, 2018 differs from the U.S Federal statutory rate for 2018 of 21% primarily due to the impact of F&G Life Re Ltd. making an election to be a US taxpayer. As a result of the election, an opening balance sheet deferred tax liability was set up resulting in a discrete expense being recorded in the first quarter. The effective tax rate on pre-tax income for the nine months ended September 30, 2017 differed from the U.S. Federal statutory rate for 2017 of 35% primarily due to a valuation allowance release within the non-life companies and favorable permanent adjustments, including low income housing credits and dividends received deduction. The effective tax rate on pre-tax income for the three months ended September 30, 2017 differed from the U.S Federal statutory rate for 2017 of 35% primarily due to a valuation allowance release within the non-life companies and the impact of favorable permanent adjustments. The TCJA amended many provisions of the Internal Revenue Code that effect on the Company. The SEC’s Staff Accounting Bulletin No. 118 (“SAB 118”) provides guidance on accounting for the effects of U.S. tax reform in circumstances in which an exact calculation cannot be made, but for which a reasonable estimate can be determined. As internal systems are updated and additional guidance becomes available, the estimate will be updated in accordance with instruction outlined in the standard and within the measurement period, which is not to extend beyond one year from the enactment date. The only provisional amount utilized in the preparation of the Company’s financial statements was tax reserves. As of the reporting date, the Company has not yet finalized the reserve impact of the TCJA. A reasonable estimate, prepared by the Company's Actuarial department, was calculated at December 31, 2017 and refined during the period ending June 30, 2018. The refinement had no impact on the Company’s ETR as the book\tax difference on tax reserves is a timing difference. No other provisions of the U.S. tax reform had a significant impact on our 2018 income tax provisions. The Company maintains a valuation allowance against most of the deferred tax assets of its non-life insurance company subsidiaries, FSRC, and the unrealized capital losses on F&G Life Re Ltd.. The Company has also placed a partial valuation allowance on its unrealized capital losses on the US life insurance subsidiaries. The non-life insurance company subsidiaries have a history of losses and insufficient sources of future income that would allow for recognition of all of their deferred tax assets. FSRC is in a cumulative loss position and does not have a sufficient track record of earnings to recognize any portion of its deferred tax assets. F&G Life Re Ltd. does not have a source of capital gain income needed to recognize its unrealized loss deferred tax assets. The Company’s US life insurance subsidiaries have sources of capital gain income, but not enough to cover all of its unrealized loss deferred tax assets. All other deferred tax assets are more likely than not to be realized based on expectations as to our future taxable income and considering all other available evidence, both positive and negative. The valuation allowance is reviewed quarterly and will be maintained until there is sufficient positive evidence to support a release. At each reporting date, management considers new evidence, both positive and negative, that could impact the future realization of deferred tax assets. Management will consider a release of the valuation allowance once there is sufficient positive evidence that it is more likely than not that the deferred tax assets will be realized. Any release of the valuation allowance will be recorded as a tax benefit increasing net income or other comprehensive income. As of September 30, 2018, the Company had a partial valuation allowance of $82 against its gross deferred tax assets of $367. The valuation allowance is an offset to most of the non-life company deferred tax assets, FSRC deferred tax assets, and F&G Life Re Ltd. and US Life Insurance Company deferred tax assets on unrealized capital losses that are considered more likely than not to be unrecoverable due to insufficient sources of future income.
