Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The Unaudited Interim Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) on a basis consistent with reporting interim financial information in accordance with instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission (“SEC”). The accompanying Unaudited Consolidated Financial Statements present the consolidated results of operations, financial condition, and cash flows of the Successor Company and a variable interest entity ("VIE") that meets the requirements for consolidation. All intercompany transactions have been eliminated in consolidation. The financial statements of the Predecessor Company were not consolidated as it was a single entity prior to acquisition. Following the acquisition of FLIAC, purchase accounting was applied to FGH's financial statements and we elected to "push down" the basis to FLIAC in accordance with Accounting Standards Codification ("ASC") 805, Business Combinations. The application of push-down accounting created a new basis of accounting for all assets and liabilities based on fair value at the date of acquisition. As a result, FLIAC's financial position, results of operations, and cash flows subsequent to the acquisition are not comparable with those prior to April 1, 2022, and therefore have been segregated to indicate pre-acquisition and post-acquisition periods. The pre-acquisition period through March 31, 2022 is referred to as the Predecessor Company. The post-acquisition period, April 1, 2022 and forward, includes the impact of push-down accounting and is referred to as the Successor Company. See Notes 1 and 2 in the Company's Annual Report on Form 10-K for the year ended December 31, 2022 for further information regarding the acquisition and our application of push-down accounting. In the opinion of management, all adjustments necessary for a fair statement of the financial position and results of operations have been made. All such adjustments are of a normal, recurring nature. Interim results are not necessarily indicative of the results that may be expected for the full year. These financial statements should be read in conjunction with the Company’s Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Reclassifications	Reclassifications Certain amounts in prior periods have been reclassified to conform to the current period presentation.
Fair Value Option	Fair Value Option We have elected to prospectively apply the fair value option to several of FLIAC's assets and liabilities. We have made this election as it improves our operational efficiency and better aligns the recognition and measurement of our investments, insurance liabilities, and associated reinsurance activity with how we expect to manage the business. See Note 6 herein and Notes 2 and 6 in the Company's Annual Report on Form 10-K for the year ended December 31, 2022 for further information.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Changes to U.S. GAAP are established by the Financial Accounting Standards Board ("FASB") in the form of an Accounting Standards Update ("ASU") to the ASC. We consider the applicability and impact of all ASUs. ASUs listed below include those that have been adopted during the current fiscal year and/or those that have been issued but not yet adopted as of the date of this filing. ASUs not listed below were assessed and determined to be either not applicable or not material. Effective ASUs - June 30, 2023 ASU 2018-12, Financial Services - Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts, was issued by the FASB. This update became effective January 1, 2023 but is not applicable due to our election to adopt the fair value option on all of our insurance liabilities, which includes our separate account liabilities. ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures, was issued by the FASB. This update became effective January 1, 2023 but is not applicable due to our election to adopt the fair value option on financial instruments that are within the scope of this update.
