Business, Basis of Presentation and Summary of Significant Accounting Policies	1. Business, Basis of Presentation and Summary of Significant Accounting Policies Business “BLIC” and the “Company” refer to Brighthouse Life Insurance Company, a Delaware corporation originally incorporated in Connecticut in 1863, and its subsidiaries. Brighthouse Life Insurance Company is a wholly-owned subsidiary of Brighthouse Holdings, LLC (“BH Holdings”) and an indirect wholly-owned subsidiary of Brighthouse Financial, Inc. (“BHF” and together with its subsidiaries, “Brighthouse Financial”). BLIC offers a range of annuity and life insurance products to individuals. The Company is organized into three segments: Annuities; Life; and Run-off. In addition, the Company reports certain of its results of operations in Corporate & Other. Basis of Presentation The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to adopt accounting policies and make estimates and assumptions that affect amounts reported on the interim condensed consolidated financial statements. In applying these policies and estimates, management makes subjective and complex judgments that frequently require assumptions about matters that are inherently uncertain. Many of these policies, estimates and related judgments are common in the insurance and financial services industries; others are specific to the Company’s business and operations. Actual results could differ from these estimates. Consolidation The accompanying interim condensed consolidated financial statements include the accounts of Brighthouse Life Insurance Company and its subsidiaries, as well as partnerships and limited liability companies (“LLC”) that the Company controls. Intercompany accounts and transactions have been eliminated. The Company uses the equity method of accounting for investments in limited partnerships and LLCs when it has more than a minor ownership interest or more than a minor influence over the investee’s operations. The Company generally recognizes its share of the investee’s earnings on a three-month lag in instances where the investee’s financial information is not sufficiently timely or when the investee’s reporting period differs from the Company’s reporting period. When the Company has virtually no influence over the investee’s operations, the investment is carried at fair value. Since the Company is a member of a controlled group of affiliated companies, its results may not be indicative of those of a standalone entity. The accompanying interim condensed consolidated financial statements are unaudited and reflect all adjustments (including normal recurring adjustments) necessary to present fairly the financial position, results of operations and cash flows for the interim periods presented in conformity with GAAP. Interim results are not necessarily indicative of full year performance. The December 31, 2021 consolidated balance sheet data was derived from audited consolidated financial statements included in Brighthouse Life Insurance Company’s Annual Report on Form 10-K for the year ended December 31, 2021 (the “2021 Annual Report”), which include all disclosures required by GAAP. Therefore, these interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements of the Company included in the 2021 Annual Report. Adoption of New Accounting Pronouncements Changes to GAAP are established by the Financial Accounting Standards Board (“FASB”) in the form of accounting standards updates (“ASU”) to the FASB Accounting Standards Codification. The Company considers the applicability and impact of all ASUs. There were no significant ASUs adopted during the period ended March 31, 2022. Future Adoption of New Accounting Pronouncements In August 2018, the FASB issued new guidance on long-duration contracts (ASU 2018-12, Financial Services-Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts). This new guidance is effective for fiscal years beginning after January 1, 2023. The amendments to Topic 944 will result in significant changes to the measurement, presentation and disclosure requirements for long-duration insurance contracts. A summary of the most significant changes is provided below: (1) Guaranteed benefits associated with variable annuity and certain fixed annuity contracts will be classified and presented separately on the consolidated balance sheets as market risk benefits (“MRB”). MRBs will be measured at fair value through net income and reported separately on the consolidated statements of operations, except for instrument-specific credit risk changes, which will be recognized in other comprehensive income (loss) (“OCI”). (2) Cash flow assumptions used to measure the liability for future policy benefits on traditional long-duration contracts (including term and non-participating whole life insurance and immediate annuities) will be updated on an annual basis using a retrospective method. The resulting remeasurement gain or loss will be reported separately on the consolidated statements of operations along with the remeasurement gain or loss on universal life-type contract liabilities. (3) The discount rate assumption used to measure the liability for traditional long-duration contracts will be based on an upper-medium grade fixed income yield, updated quarterly, with changes recognized in OCI. (4) Deferred policy acquisition costs (“DAC”) for all insurance products are required to be amortized on a constant-level basis over the expected term of the contracts, using amortization methods that are not a function of revenue or profit emergence. Changes in assumptions used to amortize DAC will be recognized as a revision to future amortization amounts. (5) There will be a significant increase in required disclosures, including disaggregated rollforwards of insurance contract assets and liabilities supplemented by qualitative and quantitative information regarding the cash flows, assumptions, methods and judgements used to measure those balances. The amendments to Topic 944 will be applied to the earliest period presented in the financial statements, making the transition date January 1, 2021. The MRB guidance is required to be applied on a retrospective basis, while the guidance for insurance liability assumption updates and DAC amortization will be applied to existing carrying amounts on the transition date. The new guidance will have a significant impact on the Company’s financial statements upon adoption, and will change the pattern and market sensitivity of the Company’s earnings after the transition date. The most significant impact will be the requirement that all variable annuity guarantees be considered MRBs and measured at fair value, because a significant amount of variable annuity guarantees are classified as insurance liabilities under current guidance. The impacts to the financial statements at adoption are highly dependent on market conditions, especially interest rates. The Company is, therefore, unable to currently estimate the ultimate impact of the new guidance on the financial statements; however, at prevailing interest rate levels at the end of 2021, the Company expects the new guidance, upon adoption, would likely result in a material decrease in stockholder’s equity.
