Related Party Transactions [Abstract]
Related Party Transactions Disclosure [Text Block]	Parent Company Transactions (Successor Company) As of December 31, 2020 and 2019, the Company had no direct employees as we are managed by TLI, the Company's parent, pursuant to an Intercompany Services and Cost Allocation Agreement effective as of June 1, 2018 (the “Management Agreement”) between the Company, TLI and other Company affiliates. Pursuant to the Management Agreement, the parties provide a variety of operating services to each other to conduct their day to day business, including employee compensation and management services. Expenses incurred by TLI in providing these services are reimbursed by the Company based on TLI’s actual cost incurred. For information related to capital contributions to the parent company, see the Dividends section of Note 13 - Statutory Results of Notes to Consolidated Financial Statements. Parent Company Transactions (Predecessor Company) Prior to the sale of the Company, substantially all general insurance expenses related to the Company were initially paid by The Hartford. Expenses were allocated to the Company using specific identification if available, or other applicable methods, that would include a blend of revenue, expense and capital. Reinsurance Ceded to Affiliates (Predecessor Company) The Company maintained a reinsurance agreement with Hartford Life and Accident Insurance Company ("HLA") whereby the Company ceded both group life and group accident and health risk business. Under this agreement, the Company ceded group life premiums of $9 for the period of January 1, 2018 to May 31, 2018 (Predecessor Company). The Company also ceded accident and health premiums of $25 for the period of January 1, 2018 to May 31, 2018 (Predecessor Company).

Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies [Text Block]	Basis of Presentation and Significant Accounting Policies Basis of Presentation Talcott Resolution Life Insurance Company, formerly Hartford Life Insurance Company, (together with its subsidiaries, “TL,” “Company,” “we” or “our”) is a provider of insurance and investment products in the United States (“U.S.”) and is a wholly-owned subsidiary of Talcott Resolution Life, Inc., a Delaware corporation ("TLI"). Hopmeadow Holdings LP (“Hopmeadow Holdings", or "HHLP ”) is the ultimate parent of the Company. The Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”), which differ materially from the accounting practices prescribed by various insurance regulatory authorities. On May 31, 2018 the Company's indirect parent, Hartford Holding, Inc. ("HHI") completed the sale of the Company's parent to a group of investors led by Cornell Capital LLC, Atlas Merchant Capital LLC, TRB Advisors LP, Global Atlantic Financial Group ("Global Atlantic"), Pine Brook and J. Safra Group. Although Talcott Resolution Life Insurance Company is no longer affiliated with The Hartford Financial Services Group, Inc. ("The Hartford") or any of its subsidiaries, The Hartford retained a 9.7 percent ownership interest in HHLP ("Talcott Resolution Sale Transaction"). In conjunction with the sale, the Company entered into a transition services agreement with The Hartford for a period up to three years to provide general ledger, cash management, and information technology infrastructure services. In 2020, the transition services agreement was completed as all supported services have fully transitioned to the Company. In March, 2019, a five year administrative services agreement was entered into for investment accounting services which replaced the services previously provided under the transition services agreement. HHLP’s May 31, 2018 acquisition of TLI was accounted for by HHLP using business combination accounting. Under this method, the purchase price paid by the investor group was assigned to the identifiable assets acquired and liabilities assumed as of the acquisition date based on their fair value. The Company elected to apply "pushdown" accounting by applying the guidance permitted under Accounting Standards Codification (“ASC”) Topic 805 Business Combinations . By the application of pushdown accounting, the Company’s assets, liabilities and equity were accordingly adjusted to fair value on May 31, 2018 which generated both intangible assets and Value of Business Acquired (“VOBA”). Determining the fair value of certain assets acquired and liabilities assumed is judgmental in nature and often involves the use of significant estimates and assumptions. Due to the application of pushdown accounting, TL’s financial statements and footnote disclosures are presented in two distinct periods to indicate the application of two different bases of accounting. The periods prior to June 1, 2018 are identified herein as “Predecessor,” while the periods subsequent to HHLP’s acquisition of TLI are identified as “Successor.” As a result of the change in the basis of accounting from historical GAAP to reflect HHLP’s purchase cost, the financial statements for the Predecessor period are not comparable to the Successor periods. On June 1, 2018, TL executed reinsurance agreements to reinsure certain fixed immediate and deferred annuity contracts, variable payout separate account annuity contracts, standard mortality structured settlements, and period certain structured settlement annuity contracts ("Commonwealth Annuity Reinsurance Agreement") to Commonwealth Annuity and Life Insurance Company ("Commonwealth"), a subsidiary of Global Atlantic which is a member of the acquiring investment group. TL reinsured an 85% quota share, except 75% for standard mortality structured settlements, in exchange for a $357 ceding commission that was fixed based on reinsuring approximately $9.3 billion of reserves as of December 31, 2016, plus annuitizations through closing and annuitizations from market value adjusted annuities post-close. The reinsurance agreement was executed after the Talcott Resolution Sale Transaction, and as such, the accounting for the agreement was recorded after the TL balance sheet was adjusted to fair value in purchase and pushdown accounting. A deferred gain, net of amortization, of $878 is recorded in Other liabilities on the Consolidated Balance Sheet related to this reinsurance agreement and will be amortized over the life of the underlying policies reinsured. COVID 19 Update The impact of the outbreak and continuing spread of the novel coronavirus (“COVID-19”) and the related disruption to the worldwide economy continues to affect companies across all industries. For the year ended December 31, 2020 (Successor Company), the COVID-19 pandemic did have varying impacts on components of revenue, however, there was no overall impact as revenues were flat year over year. The duration and impact of the COVID-19 public health crisis on financial markets, overall economy and our operations remain uncertain, as is the efficacy of government and central bank interventions. The Company successfully transitioned to a fully remote work environment in March of 2020 and remains fully remote with minimal disruption to our operations. As further discussed in this document, the Company’s financial performance is dependent on financial market conditions and potential newly emergent trends in mortality and policyholder behavior as a result of the COVID-19 public health crisis. As such, the Company continues to be unable to quantify its impact on the financial results and operations in future periods. Consolidation The Consolidated Financial Statements include the accounts of TL and entities the Company directly or indirectly has a controlling financial interest in which the Company is required to consolidate. Entities in which TL has significant influence over the operating and financing decisions but is not required to consolidate are reported using the equity method. All intercompany transactions and balances between TL and its subsidiaries have been eliminated. 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 the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates. The most significant estimates include those used in determining estimated gross profits used in the valuation and amortization of assets (including VOBA) and liabilities associated with variable annuity and other universal life-type contracts; evaluation of credit losses on fixed maturities, AFS and ACL on mortgage loans; living benefits required to be fair valued; valuation of investments and derivative instruments; valuation allowance on deferred tax assets; amortization of the deferred gain on reinsurance; and contingencies relating to corporate litigation and regulatory matters. Certain of these estimates are particularly sensitive to market conditions, and deterioration and/or volatility in the worldwide debt or equity markets could have a material impact on the Consolidated Financial Statements. The ultimate extent to which the COVID-19 pandemic will directly impact the Company's business, results of operations and financial condition will depend on future developments that are highly uncertain. Actual results may differ from these estimates. Reclassifications Certain reclassifications have been made to prior year financial information to conform to the current year presentation. Adoption of New Accounting Standards Reclassification of Effect of Tax Rate Change from AOCI to Retained Earnings In February 2018, the FASB issued new accounting guidance for the effect on deferred tax assets and liabilities related to items recorded in AOCI resulting from legislated tax reform enacted on December 22, 2017. The tax reform reduced the federal tax rate applied to the Company’s deferred tax balances from 35% to 21% on enactment. Under U.S. GAAP, the Company recorded the total effect of the change in enacted tax rates on deferred tax balances as a charge to income tax expense within net income, including the change in deferred tax balances related to components of AOCI. The new accounting guidance permitted the Company to reclassify the “stranded” tax effects out of AOCI and into retained earnings that resulted from recording the tax effects of unrealized investment gains at a 35% tax rate because the 14 point reduction in tax rate was recognized in net income instead of other comprehensive income. On January 1, 2018, the Company (Predecessor Company) adopted the new guidance and recorded a reclassification of $193 which increased AOCI and reduced retained earnings. Financial Instruments - Recognition and Measurement On January 1, 2018, the Company (Predecessor Company) adopted updated guidance issued by the FASB for the recognition and measurement of financial instruments through a cumulative effect adjustment to the opening balances of retained earnings and AOCI. The new guidance requires investments in equity securities to be measured at fair value with any changes in valuation reported in net income except for investments that are consolidated or are accounted for under the equity method of accounting. The new guidance also requires a deferred tax asset resulting from net unrealized losses on available-for-sale fixed maturities that are recognized in AOCI to be evaluated for recoverability in combination with the Company’s other deferred tax assets. Under prior guidance, the Company reported equity securities, available for sale ("AFS"), at fair value with changes in fair value reported in other comprehensive income. As of January 1, 2018, the Company (Predecessor Company) reclassified from AOCI to retained earnings net unrealized gains of $11, after tax, related to equity securities having a fair value of $154. Beginning in 2018, the Company reports equity securities at fair value with changes in fair value reported in net realized capital gains and losses. Revenue Recognition On January 1, 2018, the Company (Predecessor Company) adopted the FASB’s updated guidance for recognizing revenue from contracts with customers, which excludes insurance contracts and financial instruments. Revenue subject to the guidance is recognized when, or as, goods or services are transferred to customers in an amount that reflects the consideration that an entity is expected to receive in exchange for those goods or services. The updated guidance is consistent with previous guidance for the Company’s transactions and did not have an effect on the Company’s financial position, cash flows or net income. Revenue from customers for other than insurance and investment contracts was $80 and $84 for the years ended December 31, 2020 and 2019, respectively (Successor Company), $54 for the period of June 1, 2018 to December 31, 2018 (Successor Company) and $40 for the period of January 1, 2018 to May 31, 2018 (Predecessor Company). The Company earns revenues from these contracts primarily for administrative and distribution services fees from offering certain fund families as investment options in its variable annuity products. Fees are primarily based on the average daily net asset values of the funds and are recorded in the period in which the services are provided and collected monthly. Fluctuations in domestic and international markets and related investment performance, volume and mix of sales and redemptions of the funds, and other changes to the composition of assets under management are all factors that ultimately have a direct effect on fee income earned. Hedging Activities The FASB issued updated guidance on hedge accounting. The updates allow hedge accounting for new types of interest rate hedges of financial instruments and simplify documentation requirements to qualify for hedge accounting. In addition, any gain or loss from hedge ineffectiveness will be reported in the same income statement line with the effective hedge results and the hedged transaction. For cash flow hedges, the ineffectiveness will be recognized in earnings only when the hedged transaction affects earnings; otherwise, the ineffectiveness gains or losses will remain in AOCI. Under previous accounting, total hedge ineffectiveness was reported separately in realized gains and losses apart from the hedged transaction. The updated guidance was effective January 1, 2019 through a cumulative effect adjustment that will reclassify cumulative ineffectiveness on open cash flow hedges from retained earnings to AOCI. As a result of pushdown accounting, derivative instruments that qualified for hedge accounting were recorded at fair value through adjustments to additional paid in capital at the acquisition date. As of December 31, 2018 (Successor Company), the Company had no derivative instruments that qualify for hedge accounting, therefore there was no impact on the Company's financial statements upon adoption. Changes to the Disclosure Requirements for Fair Value Measurement On August 28, 2018 the FASB issued Accounting Standards Update ("ASU") 2018-13 which removes, modifies and adds certain disclosure requirements related to fair value measurements in ASC 820, Fair Value Measurements . As permitted by the guidance, the Company early adopted amendments in this guidance effective December 31, 2019. The adoption of ASU 2018-13 did not have a material impact on the Company's consolidated financial statements. Financial Instruments - Credit Losses On January 1, 2020 the Company adopted ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments, ("ASU 2016-13", or "CECL") together with related updated guidance for recognition and measurement of credit losses on certain financial instruments not carried at fair value, including reinsurance recoverables. This guidance replaces the “incurred loss” approach with an “expected loss” model for recognizing credit losses for instruments carried at amortized cost, which resulted in the recognition of greater allowances for losses. Under the new model, an allowance for credit losses ("ACL") is recognized as an estimate of credit losses expected over the life of financial instruments, such as mortgage loans, reinsurance recoverables and off-balance sheet credit exposures that the Company cannot unconditionally cancel. The measurement of the expected credit loss estimate is based on historical loss data, current conditions, and reasonable and supportable forecasts. Credit losses on fixed maturities, AFS carried at fair value continue to be measured similar to previous guidance for other-than-temporary impairments ("OTTI"); however, losses are now recognized through the ACL and no longer as an adjustment to the amortized cost. Recoveries of OTTI on fixed maturities, AFS are recognized as reversals of the ACL recognized through net realized capital gains and losses and no longer accreted as net investment income through an adjustment to the investment yield. For fixed maturities, AFS this guidance is applied prospectively. Additionally, the new guidance requires purchased financial assets with a more-than-insignificant amount of credit deterioration since original issuance to establish an ACL at acquisition, which is recorded with the purchase price to establish the initial amortized cost of the investment. The Company adopted the guidance through a cumulative-effect adjustment that decreased retained earnings by $11, after tax, primarily related to the Company's mortgage loan investments. No ACL was recognized at adoption for fixed maturities, AFS as those provisions of the guidance are applied prospectively. Upon adoption, the Company did not have any purchased financial assets with a more-than-insignificant amount of credit deterioration since original issuance. Summary of Adoption Impacts ACL on mortgage loans $ (9) ACL on reinsurance recoverables (5) Deferred income tax asset 3 Net decrease to retained earnings $ (11) Future Adoption of New Accounting Standards Targeted Improvements to the Accounting for Long Duration Contracts The FASB issued ASU 2018-12 on August 15, 2018 which impacts the existing recognition, measurement, presentation and disclosure requirements for certain long duration contracts issued by an insurance company. The guidance is intended to improve the timeliness of recognizing changes in the liability for future policy benefits by requiring annual or more frequent updates of insurance assumptions and modifying the rate used to discount future cash flows. Cash flows under the new guidance are required to be discounted using an upper-medium grade fixed income instrument yield. The discount rate is required to be updated at each reporting date, with the effect of discount rate changes on the liability recorded in OCI. This is a change from current GAAP which utilizes assumptions, including discount rate, "locked in" at policy issuance and until such time significant changes in experience or assumptions may require the Company to establish premium deficiency reserves. When this occurs, premium deficiency reserves are recognized by unlocking reserve assumptions to eliminate a reserve deficiency under current GAAP. Further, the guidance seeks to improve the accounting for certain market-based options or guarantees associated with account balance contracts and improve the effectiveness of the required disclosures. These market risk benefit features are required to be measured at fair value with changes in fair value recorded in net income with the exception of changes in the fair value attributable to a change in the instrument's credit risk, which are required to be recognized in OCI. Additionally, this ASU requires new disclosures including liability rollforwards and information about significant inputs, judgments, assumptions, and methods used in the measurement. This guidance was amended through the issuance of ASU 2020-11, which deferred the effective date the Company is required to adopt the guidance to January 1, 2023, with early adoption permitted. The Company continues to assess its policies, processes, and applicable systems to determine the impact this standard will have on its operations and financial results. While it is not possible to reasonably estimate the expected impact of adoption at this time, given the nature and extent of the required changes to a significant portion of the Company’s operations, adoption is expected to have a material impact on our consolidated financial statements and related disclosures. This guidance represents a significant change from existing GAAP; however, it does not change the underlying economics of the business or its related cash flows. Significant Accounting Policies The Company’s significant accounting policies are as follows: Segment Information The Company has no reportable segments and its principal products and services are comprised of variable annuities, fixed and payout annuities, and private-placement life insurance. The Company's determination that it has no reportable segments is based on the fact that the Company's chief operating decision maker reviews the Company's financial performance at a consolidated level. Revenue Recognition For investment and universal life-type contracts, the amounts collected from policyholders are considered deposits and are not included in revenue. Fee income for variable annuity and other universal life-type contracts consists of policy charges for policy administration, cost of insurance charges and surrender charges assessed against policyholders’ account balances and are recognized in the period in which services are provided. For the Company’s traditional life products, premiums are recognized as revenue when due from policyholders. Income Taxes The Company recognizes taxes payable or refundable for the current year and deferred taxes for the tax consequences of temporary differences between the financial reporting and tax basis of assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years the temporary differences are expected to reverse. A deferred tax provision is recorded for the tax effects of differences between the Company's current taxable income and its income before tax under generally accepted accounting principles in the Consolidated Statements of Operations. For deferred tax assets, the Company records a valuation allowance that is adequate to reduce the total deferred tax asset to an amount that will more likely than not be realized. Investments Overview The Company’s investments in fixed maturities include bonds, structured securities, redeemable preferred stock and commercial paper. Most of these investments are classified as AFS and are carried at fair value, net of ACL, in accordance with new guidance adopted January 1, 2020 regarding expected credit losses. The after-tax difference between fair value and cost or amortized cost is reflected in stockholder's equity as a component of AOCI, after adjustments for the effect of VOBA (Successor Company) and reserve adjustments. Equity securities are measured at fair value with any changes in valuation reported in net income. For further information, see Financial Instruments - Recognition and Measurement discussion above. Policy loans are carried at outstanding balance. Mortgage loans are recorded at the outstanding principal balance adjusted for amortization of premiums or discounts and net of ACL. Short-term investments are carried at amortized cost, which approximates fair value. Limited partnerships and other alternative investments are reported at their carrying value and are primarily accounted for under the equity method with the Company’s share of earnings included in net investment income. Recognition of income related to limited partnerships and other alternative investments is delayed due to the availability of the related financial information, as private equity and other funds are generally on a three-month lag and hedge funds on a one-month lag. Accordingly, income for the years ended December 31, 2020 and 2019 (Successor Company), the period of June 1, 2018 to December 31, 2018 (Successor Company) and and the period of January 1, 2018 to May 31, 2018 (Predecessor Company) may not include the full impact of current year changes in valuation of the underlying assets and liabilities of the funds, which are generally obtained from the limited partnerships and other alternative investments’ general partners. Other investments consist of derivative instruments which are carried at fair value and real estate acquired in satisfaction of debt. Net Realized Capital Gains and Losses Net realized capital gains and losses from investment sales are reported as a component of revenues and are determined on a specific identification basis. Net realized capital gains and losses also result from fair value changes in equity securities and derivatives contracts (both free-standing and embedded) that do not qualify, or are not designated, as a hedge for accounting purposes. Impairments and changes in the ACL on fixed maturities, AFS; mortgage loans; and reinsurance recoverables are recognized as net realized capital losses in accordance with the Company’s impairment and ACL policies as discussed in Note 3 - Investments of Notes to Consolidated Financial Statements. Foreign currency transaction remeasurements are also included in net realized capital gains and losses. Net Investment Income Interest income from fixed maturities and mortgage loans is recognized when earned on the constant effective yield method based on estimated timing of cash flows. The amortization of premium and accretion of discount for fixed maturities also takes into consideration call and maturity dates that produce the lowest yield. For securitized financial assets subject to prepayment risk, yields are recalculated and adjusted periodically to reflect historical and/or estimated future prepayments using the retrospective method; however, if these investments have previously recognized an ACL and for certain other asset-backed securities, any yield adjustments are made using the prospective method. Prepayment fees and make-whole payments on fixed maturities and mortgage loans are recorded in net investment income when earned. For equity securities, dividends are recognized as investment income on the ex-dividend date. Limited partnerships and other alternative investments primarily use the equity method of accounting to recognize the Company’s share of earnings. Prior to January 1, 2020 the Company applied OTTI guidance to debt securities in an unrealized loss position and accreted the new cost basis to the estimated future cash flows over the expected remaining life of the security by prospectively adjusting the security’s yield, if necessary. In accordance with accounting guidance adopted January 1, 2020 regarding expected credit losses, the losses are now recognized through an ACL and no longer as an adjustment to amortized cost. The Company’s non-income producing investments were not material for the years ended December 31, 2020 and 2019, (Successor Company), the period of June 1, 2018 to December 31, 2018 (Successor Company) and the period of January 1, 2018 to May 31, 2018 (Predecessor Company). Derivative Instruments Overview The Company utilizes a variety of over-the-counter ("OTC") transactions cleared through central clearing houses ("OTC-cleared") and exchange traded derivative instruments as part of its overall risk management strategy as well as to enter into replication transactions. The types of instruments may include swaps, caps, floors, forwards, futures and options to achieve one of four Company-approved objectives: • to hedge risk arising from interest rate, equity market, commodity market, credit spread and issuer default, price or currency exchange rate risk or volatility; • to manage liquidity; • to control transaction costs; • to enter into synthetic replication transactions. Interest rate and credit default swaps involve the periodic exchange of cash flows with other parties, at specified intervals, calculated using agreed upon rates or other financial variables and notional principal amounts. Generally, little to no cash or principal payments are exchanged at the inception of the contract. Typically, at the time a swap is entered into, the cash flow streams exchanged by the counterparties are equal in value. Interest rate cap and floor contracts entitle the purchaser to receive from the issuer at specified dates, the amount, if any, by which a specified market rate exceeds the cap strike interest rate or falls below the floor strike interest rate, applied to a notional principal amount. A premium payment determined at inception is made by the purchaser of the contract and no principal payments are exchanged. Forward contracts are customized commitments that specify a rate of interest or currency exchange rate to be paid or received on an obligation beginning on a future start date and are typically settled in cash. Financial futures are standardized commitments to either purchase or sell designated financial instruments, at a future date, for a specified price and may be settled in cash or through delivery of the underlying instrument. Futures contracts trade on organized exchanges. Margin requirements for futures are met by pledging securities or cash, and changes in the futures’ contract values are settled daily in cash. Option contracts grant the purchaser, for a premium payment, the right to either purchase from or sell to the issuer a financial instrument at a specified price, within a specified period or on a stated date. The contracts may reference commodities, which grant the purchaser the right to either purchase from or sell to the issuer commodities at a specified price, within a specified period or on a stated date. Option contracts are typically settled in cash. Foreign currency swaps exchange an initial principal amount in two currencies, agreeing to re-exchange the currencies at a future date, at an agreed upon exchange rate. There may also be a periodic exchange of payments at specified intervals calculated using the agreed upon rates and exchanged principal amounts. The Company’s derivative transactions conducted in insurance company subsidiaries are used in strategies permitted under the derivative use plans required by the State of Connecticut and the State of New York insurance departments. Accounting and Financial Statement Presentation of Derivative Instruments and Hedging Activities Derivative instruments are recognized on the Consolidated Balance Sheets at fair value and are reported in Other Investments and Other Liabilities. For balance sheet presentation purposes, the Company has elected to offset the fair value amounts, income accruals, and related cash collateral receivables and payables of OTC derivative instruments executed in a legal entity and with the same counterparty or under a master netting agreement, which provides the Company with the legal right of offset. The Company clears certain interest rate swap and credit default swap derivative transactions through central clearing houses. OTC-cleared derivatives require initial collateral at the inception of the trade in the form of cash or highly liquid securities, such as U.S. Treasuries and government agency investments. Central clearing houses also require additional cash as variation margin based on daily market value movements. For information on collateral, see the derivative collateral arrangements section in Note 4 - Derivative Instruments of Notes to Consolidated Financial Statements. In addition, OTC-cleared transactions include price alignment amounts either received or paid on the variation margin, which are reflected in realized capital gains and losses or, if characterized as interest, in net investment income. On the date the derivative contract is entered into, the Company designates the derivative as (1) a hedge of the variability in cash flows of a forecasted transaction or of amounts to be received or paid related to a recognized asset or liability (“cash flow” hedge), (2) a hedge of a net investment in a foreign operation (“net investment” hedge) or (3) held for other investment and/or risk management purposes, which primarily involve managing asset or liability related risks and do not qualify for hedge accounting. Cash Flow Hedges - Changes in the fair value of a derivative that is designated and qualifies as a cash flow hedge, including foreign-currency cash flow hedges, are recorded in AOCI and are reclassified into earnings when the variability of the cash flow of the hedged item impacts earnings. Gains and losses on derivative contracts that are reclassified from AOCI to current period earnings are included in the line item in the Consolidated Statements of Operations in which the cash flows of the hedged item are recorded. For periods prior to 2019, hedge ineffectiveness was recorded immediately in current period earnings as net realized capital gains and losses. With the January 1, 2019 adoption of the updated FASB hedging guidance, ineffectiveness is recognized in earnings only when the hedged transaction affects earnings; otherwise, the ineffectiveness gains and losses remain in AOCI. Periodic derivative net coupon settlements are recorded in the line item of the Consolidated Statements of Operations in which the cash flows of the hedged item are recorded. Cash flows from cash flow hedges are presented in the same category as the cash flows from the items being hedged on the Consolidated Statements of Cash Flows. Other Investment and/or Risk Management Activities - The Company’s other investment and/or risk management activities primarily relate to strategies used to reduce economic risk or replicate permitted investments and do not receive hedge accounting treatment. Changes in the fair value, including periodic derivative net coupon settlements, of derivative instruments held for other investment and/or risk management purposes are reported in current period earnings as net realized capital gains and losses.

Fair Value Disclosures [Abstract]
Fair Value Measurements	The Company carries certain financial assets and liabilities at estimated fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants. Our fair value framework includes a hierarchy that gives the highest priority to the use of quoted prices in active markets, followed by the use of market observable inputs, followed by the use of unobservable inputs. The fair value hierarchy levels are as follows: Level 1 Fair values based primarily on unadjusted quoted prices for identical assets, or liabilities, in active markets that the Company has the ability to access at the measurement date. Level 2 Fair values primarily based on observable inputs, other than quoted prices included in Level 1, or based on prices for similar assets and liabilities. Level 3 Fair values derived when one or more of the significant inputs are unobservable (including assumptions about risk). With little or no observable market, the determination of fair values uses considerable judgment and represents the Company’s best estimate of an amount that could be realized in a market exchange for the asset or liability. Also included are securities that are traded within illiquid markets and/or priced by independent brokers. The Company will classify the financial asset or liability by level based upon the lowest level input that is significant to the determination of the fair value. In most cases, both observable inputs (e.g., changes in interest rates) and unobservable inputs (e.g., changes in risk assumptions) are used to determine fair values that the Company has classified within Level 3.

See footnote 3 to this table for derivative liabilities. [2] Approximately $877 and $2.4 billion of investment sales receivables, as of December 31, 2020 and 2019 (Successor Company), respectively, are excluded from this disclosure requirement because they are trade receivables in the ordinary course of business where the carrying amount approximates fair value. Included in the total fair value amount are $441 and $461 of investments, as of December 31, 2020 and 2019 (Successor Company), respectively, for which the fair value is estimated using the net asset value per unit as a practical expedient which are excluded from the disclosure requirement to classify amounts in the fair value hierarchy. [3] Includes derivative instruments in a net negative fair value position (derivative liability) after consideration of the accrued interest and impact of collateral posting requirements which may be imposed by agreements and applicable law. Fixed Maturities, Equity Securities, Short-term Investments, and Free-standing Derivatives Valuation Techniques The Company generally determines fair values using valuation techniques that use prices, rates, and other relevant information evident from market transactions involving identical or similar instruments. Valuation techniques also include, where appropriate, estimates of future cash flows that are converted into a single discounted amount using current market expectations. The Company uses a "waterfall" approach comprised of the following pricing sources and techniques, which are listed in priority order: • Quoted prices, unadjusted, for identical assets or liabilities in active markets, which are classified as Level 1. • Prices from third-party pricing services, which primarily utilize a combination of techniques. These services utilize recently reported trades of identical, similar, or benchmark securities making adjustments for market observable inputs available through the reporting date. If there are no recently reported trades, they may use a discounted cash flow technique to develop a price using expected cash flows based upon the anticipated future performance of the underlying collateral discounted at an estimated market rate. Both techniques develop prices that consider the time value of future cash flows and provide a margin for risk, including liquidity and credit risk. Most prices provided by third-party pricing services are classified as Level 2 because the inputs used in pricing the securities are observable. However, some securities that are less liquid or trade less actively are classified as Level 3. Additionally, certain long-dated securities, such as municipal securities and bank loans, include benchmark interest rate or credit spread assumptions that are not observable in the marketplace and are thus classified as Level 3. • Internal matrix pricing, which is a valuation process internally developed for private placement securities for which the Company is unable to obtain a price from a third-party pricing service. Internal pricing matrices determine credit spreads that, when combined with risk-free rates, are applied to contractual cash flows to develop a price. The Company develops credit spreads using market based data for public securities adjusted for credit spread differentials between public and private securities, which are obtained from a survey of multiple private placement brokers. The market-based reference credit spread considers the issuer’s financial strength and term to maturity, using an independent public security index, while the credit spread differential considers the non-public nature of the security. Securities priced using internal matrix pricing are classified as Level 2 because the inputs are observable or can be corroborated with observable data. • Independent broker quotes, which are typically non-binding use inputs that can be difficult to corroborate with observable market based data. Brokers may use present value techniques using assumptions specific to the security types, or they may use recent transactions of similar securities. Due to the lack of transparency in the process that brokers use to develop prices, valuations that are based on independent broker quotes are classified as Level 3. The fair value of free-standing derivative instruments is determined primarily using a discounted cash flow model or option model technique and incorporates counterparty credit risk. In some cases, quoted market prices for exchange-traded and OTC cleared derivatives may be used and in other cases independent broker quotes may be used. The pricing valuation models primarily use inputs that are observable in the market or can be corroborated by observable market data. The valuation of certain derivatives may include significant inputs that are unobservable, such as volatility levels, and reflect the Company’s view of what other market participants would use when pricing such instruments. Unobservable market data is used in the valuation of customized derivatives that are used to hedge certain GMWB variable annuity riders. See the section “GMWB Embedded, Customized, and Reinsurance Derivatives” below for further discussion of the valuation model used to value these customized derivatives. Valuation Inputs Quoted prices for identical assets in active markets are considered Level 1 and consist of on-the-run U.S. Treasuries, money market funds, exchange-traded equity securities, open-ended mutual funds, certain short-term investments, and exchange traded futures and option contracts. Valuation Inputs Used in Levels 2 and 3 Measurements for Securities and Freestanding Derivatives Level 2 Level 3 Fixed Maturity Investments Structured securities (includes ABS, CLOs, CMBS and RMBS) • Benchmark yields and spreads Other inputs for ABS, CLOs, and RMBS: • Independent broker quotes Other inputs for less liquid securities or those that trade less actively, including subprime RMBS: Corporates • Benchmark yields and spreads Other inputs for investment grade privately placed securities that utilize internal matrix pricing: • Independent broker quotes Other inputs for below investment grade privately placed securities: U.S Treasuries, Municipals, and Foreign government/government agencies • Benchmark yields and spreads • Credit spreads beyond observable curve Equity Securities • Quoted prices in markets that are not active • For privately traded equity securities, internal discounted cash flow models utilizing earnings multiples or other cash flow assumptions that are not observable Short-term Investments • Benchmark yields and spreads • Independent broker quotes Derivatives Credit derivatives • Swap yield curve Not applicable Equity derivatives • Equity index levels • Independent broker quotes Foreign exchange derivatives • Swap yield curve Not applicable Interest rate derivatives • Swap yield curve • Independent broker quotes Significant Unobservable Inputs for Level 3 - Securities As of December 31, 2020 (Successor Company) Assets Accounted for at Fair Value on a Recurring Basis Fair Value Predominant Significant Unobservable Input Minimum Maximum Weighted Average [1] Impact of Increase in Input on Fair Value [2] CLOs [3] $ 259 Discounted cash flows Spread 249bps 305bps 304bps Decrease CMBS [3] 49 Discounted cash flows Spread (encompasses 255bps 1,582bps 570bps Decrease Corporate [4] 269 Discounted cash flows Spread 116bps 1,210bps 304bps Decrease RMBS [3] 154 Discounted cash flows Spread [6] 7bps 592bps 119bps Decrease Constant prepayment rate [6] —% 10% 5% Decrease [5] Constant default rate [6] 2% 6% 3% Decrease Loss severity [6] —% 100% 81% Decrease As of December 31, 2019 (Successor Company) Assets accounted for at Fair Value on a Recurring Basis Fair Value Predominant Significant Unobservable Input Minimum Maximum Weighted Average [1] Impact of Increase in Input on Fair Value [2] CLOs [3] $ 58 Discounted cash flows Spread 113bps 246bps 243bps Decrease CMBS [3] 37 Discounted cash flows Spread (encompasses 9bps 1,832bps 266bps Decrease Corporate [4] 309 Discounted cash flows Spread 93bps 823bps 236bps Decrease RMBS [3] 247 Discounted cash flows Spread [6] 5bps 233bps 82bps Decrease Constant prepayment rate [6] —% 13% 6% Decrease [5] Constant default rate [6] 2% 5% 3% Decrease Loss severity [6] —% 100% 70% Decrease [1] The weighted average is determined based on the fair value of the securities.

[6] Generally, a change in the assumption used for the constant default rate would have been accompanied by a directionally similar change in the assumption used for the loss severity and a directionally opposite change in the assumption used for constant prepayment rate and would have resulted in wider spreads. The tables below exclude certain securities for which fair values are predominately based on independent broker quotes.

Changes in fair value will be inversely impacted for short positions. [3] Excludes derivatives for which the Company bases fair value on broker quotations. [4] Includes activity previously reported as GMWB hedging instruments. For further discussion please refer to GMWB Derivatives, net in Footnote 4 - Derivative Instruments of Notes to Consolidated Financial Statements. GMWB Embedded, Customized and Reinsurance Derivatives GMWB Embedded Derivatives The Company formerly offered certain variable annuity products with GMWB riders that provide the policyholder with a guaranteed remaining balance ("GRB") which is generally equal to premiums less withdrawals. If the policyholder’s account value is reduced to a specified level through a combination of market declines and withdrawals but the GRB still has value, the Company is obligated to continue to make annuity payments to the policyholder until the GRB is exhausted. When payments of the GRB are not life-contingent, the GMWB represents an embedded derivative carried at fair value reported in other policyholder funds and benefits payable on the Consolidated Balance Sheets with changes in fair value reported in net realized capital gains and losses. Free-standing Customized Derivatives The Company holds free-standing customized derivative contracts to provide protection from certain capital markets risks for the remaining term of specified blocks of non-reinsured GMWB riders. These customized derivatives are based on policyholder behavior assumptions specified at the inception of the derivative contracts. The Company retains the risk for differences between assumed and actual policyholder behavior and between the performance of the actively managed funds underlying the separate accounts and their respective indices. These derivatives are reported on the Consolidated Balance Sheets within other investments or other liabilities, as appropriate, after considering the impact of master netting agreements. GMWB Reinsurance Derivative The Company has reinsurance arrangements in place to transfer a portion of its risk of loss due to GMWB. These arrangements are recognized as derivatives carried at fair value and reported in reinsurance recoverables on the Consolidated Balance Sheets. Changes in the fair value of the reinsurance agreements are reported in net realized capital gains and losses. Valuation Techniques Fair values for GMWB embedded derivatives, free-standing customized derivatives and reinsurance derivatives are classified as Level 3 in the fair value hierarchy and are calculated using internally developed models that utilize significant unobservable inputs because active, observable markets do not exist for these items. In valuing the GMWB embedded derivative, the Company attributes to the derivative a portion of the expected fees to be collected over the expected life of the contract from the contract holder equal to the present value of future GMWB claims. The excess of fees collected from the contract holder in the current period over the portion of fees attributed to the embedded derivative in the current period are associated with the host variable annuity contract and reported in fee income. Valuation Inputs The fair value for each of the non-life contingent GMWBs, the free-standing customized derivatives and the GMWB reinsurance derivative is calculated as an aggregation of the following components: Best Estimate Claim Payments; Credit Standing Adjustment; and Margins. The Company believes the aggregation of these components results in an amount that a market participant in an active liquid market would require, if such a market existed, to assume the risks associated with the guaranteed minimum benefits and the related reinsurance and customized derivatives. Each component described in the following discussion is unobservable in the marketplace and requires subjectivity by the Company in determining its value. Best Estimate Claim Payments The Best Estimate Claim Payments are calculated based on actuarial and capital market assumptions related to projected cash flows, including the present value of benefits and related contract charges, over the lives of the contracts, incorporating unobservable inputs including expectations concerning policyholder behavior. Credit Standing Adjustment The credit standing adjustment is an estimate of the adjustment to the fair value that market participants would require in determining fair value to reflect the risk that GMWB benefit obligations or the GMWB reinsurance recoverables will not be fulfilled. The Company incorporates a blend of estimates of peer company and reinsurer bond spreads and credit default spreads from capital markets, adjusted for market recoverability. Margins The behavior risk margin adds a margin that market participants would require, in determining fair value, for the risk that the Company’s assumptions about policyholder behavior could differ from actual experience. The behavior risk margin is calculated by taking the difference between adverse policyholder behavior assumptions and best estimate assumptions. Valuation Inputs Used in Levels 2 and 3 Measurements for GMWB Embedded, Customized and Reinsurance Derivatives Level 2 Level 3 • Risk-free rates as represented by the Eurodollar futures, LIBOR deposits and swap rates to derive forward curve rates • Market implied equity volatility assumptions Assumptions about policyholder behavior, including: Significant Unobservable Inputs for Level 3 GMWB Embedded Customized and Reinsurance Derivatives As of December 31, 2020 (Successor Company) Unobservable Inputs (Minimum) Unobservable Inputs (Maximum) Weighted Impact of Increase in Input Withdrawal Utilization [2] —% 100% 62% Increase Withdrawal Rates [3] 4% 8% 6% Increase Lapse Rates [4] —% 55% 5% Decrease [8] Reset Elections [5] —% 99% 8% Decrease [8] Equity Volatility [6] 16% 28% 21% Increase Credit standing adjustment [7] 0.18% 0.45% 0.34% Decrease As of December 31, 2019 (Successor Company) Unobservable Inputs (Minimum) Unobservable Inputs (Maximum) Weighted Impact of Increase in Input Withdrawal Utilization [2] 19% 100% 69% Increase Withdrawal Rates [3] —% 7% 6% Increase Lapse Rates [4] —% 61% 6% Decrease [8] Reset Elections [5] —% 100% 11% Increase Equity Volatility [6] 10% 25% 19% Increase Credit standing adjustment [7] 0.07% 0.26% 0.17% Decrease [1] Conversely, the impact of a decrease in input would have the opposite impact to the fair value as that presented in the table. [2] Range represents assumed percentages of policyholders taking withdrawals. [3] Range represents assumed annual percentage of allowable amount withdrawn. [4] Range represents assumed annual percentages of policyholders electing a full surrender. [5] Range represents assumed annual percentages of eligible policyholders electing to reset their guaranteed benefit base. [6] Range represents implied market volatilities for equity indices based on multiple pricing sources. [7] Range represents Company credit spreads, adjusted for market recoverability. [8] The impact may be an increase for some contracts, particularly those with out of the money guarantees. Separate Account Assets Separate account assets are primarily invested in mutual funds. Other separate account assets include fixed maturities, limited partnerships, equity securities, short-term investments and derivatives that are valued in the same manner, and using the same pricing sources and inputs, as those investments held by the Company. For limited partnerships in which fair value represents the separate account’s share of the NAV, 43% and 49% were subject to significant liquidation restrictions as of December 31, 2020 and 2019 (Successor Company), respectively. Total limited partnerships that do not allow any form of redemption were 0% as of December 31, 2020 and 2019 (Successor Company), respectively. Separate account assets classified as Level 3 primarily include long-dated bank loans, subprime RMBS and commercial mortgage loans. Level 3 Assets and Liabilities Measured at Fair Value on a Recurring Basis Using Significant Unobservable Inputs The Company uses derivative instruments to manage the risk associated with certain assets and liabilities. However, the derivative instrument may not be classified with the same fair value hierarchy level as the associated asset or liability. Therefore, the realized and unrealized gains and losses on derivatives reported in the Level 3 roll-forward may be offset by realized and unrealized gains and losses of the associated assets and liabilities in other line items of the financial statements. The following table presents a reconciliation of the beginning and ending balances for fair value measurements for the year ended December 31, 2020 (Successor Company), for which the Company had used significant unobservable inputs (Level 3): Fair Value Roll-forwards for Financial Instruments Classified as Level 3 Total Realized/Unrealized Gains (Losses) Fair Value as of January 1, 2020 Included in Net Income [1] [2] [6] Included in OCI [3] Purchases Settlements Sales Transfers into Transfers out of Level 3 [4] Fair Value as of December 31, 2020 Assets Fixed maturities, AFS ABS $ 13 $ — $ (1) $ 40 $ — $ — $ — $ (52) $ — CLOs 58 — 2 237 (28) — — (10) 259 CMBS 37 — (3) 18 — — 2 — 54 Corporate 387 2 12 51 (40) (24) 357 (417) 328 RMBS 247 — — 57 (64) (28) — (58) 154 Total fixed maturities, AFS 742 2 10 403 (132) (52) 359 (537) 795 Equity securities, at fair value 33 — — 1 — (2) — — 32 Freestanding derivatives Interest rate (2) 4 — — — — — — 2 GMWB hedging instruments 38 (38) — — — — — — — Total freestanding derivatives [5] 36 (34) — — — — — — 2 Reinsurance recoverable for GMWB 17 (21) — — 11 — — — 7 Separate accounts 23 — — 12 — (7) — (8) 20 Short-term investments 6 — — 22 (6) — — — 22 Total assets $ 857 $ (53) $ 10 $ 438 $ (127) $ (61) $ 359 $ (545) $ 878 (Liabilities) Freestanding derivatives Macro hedge program (113) (456) — 339 (211) — — — (441) Total freestanding derivatives [5] (113) (456) — 339 (211) — — — (441) Other policyholder funds and benefits payable Guaranteed withdrawal benefits 5 67 — — (51) — — — 21 Total other policyholder funds and benefits payable 5 67 — — (51) — — — 21 Total liabilities $ (108) $ (389) $ — $ 339 $ (262) $ — $ — $ — $ (420) The following table presents a reconciliation of the beginning and ending balances for fair value measurements for the year ended December 31, 2019 (Successor Company), for which the Company had used significant unobservable inputs (Level 3): Fair Value Roll-forwards for Financial Instruments Classified as Level 3 Total Realized/Unrealized Gains (Losses) Fair Value as of January 1, 2019 Included in Net Income [1] [2] [6] Included in OCI [3] Purchases Settlements Sales Transfers into Transfers out of Level 3 [4] Fair Value as of December 31, 2019 Assets Fixed maturities, AFS ABS $ 2 $ — $ — $ 13 $ — $ — $ — $ (2) $ 13 CLOs 77 — — 155 (91) (5) — (78) 58 CMBS 41 — 2 53 (1) — — (58) 37 Corporate 327 (3) 16 41 (15) (106) 138 (11) 387 RMBS 443 — 1 — (75) (105) — (17) 247 Total fixed maturities, AFS 890 (3) 19 262 (182) (216) 138 (166) 742 Equity securities, at fair value 46 (4) — 2 (1) (10) — — 33 Freestanding derivatives Equity — (1) — 1 — — — — — GMWB hedging instruments 45 (35) — — 28 — — — 38 Total freestanding derivatives [5] 45 (36) — 1 28 — — — 38 Reinsurance recoverable for GMWB 40 (34) — — 11 — — — 17 Separate accounts 40 — — 82 — (14) 12 (97) 23 Short-term investments — — — 6 — — — — 6 Total assets $ 1,061 $ (77) $ 19 $ 353 $ (144) $ (240) $ 150 $ (263) $ 859 (Liabilities) Freestanding derivatives Interest rate $ (27) $ (6) $ — $ — $ 31 $ — $ — $ — $ (2) Macro hedge program 247 (359) — (1) — — — — (113) Total freestanding derivatives [5] 220 (365) — (1) 31 — — — (115) Other policyholder funds and benefits payable Guaranteed withdrawal benefits (80) 134 — — (49) — — — 5 Total other policyholder funds and benefits payable (80) 134 — — (49) — — — 5 Total liabilities $ 140 $ (231) $ — $ (1) $ (18) $ — $ — $ — $ (110) [1] The Company classifies realized and unrealized gains (losses) on GMWB reinsurance derivatives and GMWB embedded derivatives as unrealized gains (losses) for purposes of disclosure in this table because it is impracticable to track on a contract-by-contract basis the realized gains (losses) for these derivatives and embedded derivatives. [2] Amounts in these columns are generally reported in net realized capital gains (losses). The realized/unrealized gains (losses) included in net income for separate account assets are offset by an equal amount for separate account liabilities, which results in a net zero impact on net income for the Company. All amounts are before income taxes and amortization. [3] All amounts are before income taxes and amortization. [4] Transfers in and/or (out) of Level 3 are primarily attributable to the availability of market observable information and the re-evaluation of the observability of pricing inputs. Transfers into and out of Level 3 for the year ended December 31, 2020, were primarily related to private securities that were priced using internal matrix pricing in the prior period, but changed to broker pricing in the current period and inversely, private securities that were priced using broker pricing in the prior period, but changed to internal matrix pricing in the current period.

Accrued Interest Receivable on Fixed Maturities, AFS and Mortgage Loans As of December 31, 2020 and 2019 (Successor Company), the Company reported accrued interest receivable related to fixed maturities, AFS of $114 and $122, respectively, and accrued interest receivable related to mortgage loans of $7 and $8, respectively. These amounts are recorded in other assets on the Consolidated Balance Sheets and are not included in the amortized cost or fair value of the fixed maturities or mortgage loans. The Company does not include the current accrued interest receivable balance when estimating the ACL. The Company has a policy to write-off accrued interest receivable balances that are more than 90 days past due. Write-offs of accrued interest receivable are recorded as a credit loss component of realized capital gains and losses. Interest income on fixed maturities and mortgage loans is accrued unless it is past due over 90 days or management deems the interest uncollectible. Recognition and Presentation of Intent-to-Sell Impairments and ACL on Fixed Maturities, AFS The Company will record an "intent-to-sell impairment" as a reduction to the amortized cost of fixed maturities, AFS in an unrealized loss position if the Company intends to sell or it is more likely than not that the Company will be required to sell the fixed maturity before a recovery in value. A corresponding charge is recorded in net realized capital losses equal to the difference between the fair value on the impairment date and the amortized cost basis of the fixed maturity before recognizing the impairment. When fixed maturities are in an unrealized loss position and the Company does not record an intent-to-sell impairment, the Company will record an ACL, through net realized capital gains and losses, for the portion of the unrealized loss due to a credit loss. Any remaining unrealized loss on a fixed maturity after recording an ACL is the non-credit amount and is recorded in OCI. The ACL is the excess of the amortized cost over the greater of the Company's best estimate of the present value of expected future cash flows or the security's fair value. Cash flows are discounted at the effective yield that is used to record interest income. The ACL cannot exceed the unrealized loss and, therefore, it may fluctuate with changes in the fair value of the fixed maturity if the fair value is greater than the Company's best estimate of the present value of expected future cash flows. The initial ACL and any subsequent changes are recorded in net realized capital gains and losses. The ACL is written off against the amortized cost in the period in which all or a portion of the related fixed maturity investment is determined to be uncollectible. Prior to January 1, 2020, the Company recorded an OTTI for those fixed maturities for which the Company did not expect to recover the entire amortized cost basis. For these securities, the excess of the amortized cost basis over its fair value was separated into the portion representing a credit OTTI, which was recorded in net realized capital losses, and the remaining non-credit amount, which was recorded in OCI. The credit OTTI amount is the excess of its amortized cost basis over the Company’s best estimate of discounted expected future cash flows. The non-credit amount is the excess of the best estimate of the discounted expected future cash flows over the fair value.The Company’s best estimate of discounted expected future cash flows became the new cost basis and accreted prospectively into net investment income over the estimated remaining life of the security. Amounts previously recognized in accumulated other comprehensive income as of the ASU 2016-13 guidance adoption date that relate to improvements in cash flows expected to be collected will continue to be accreted into income over the asset's remaining life. Developing the Company’s best estimate of expected future cash flows is a quantitative and qualitative process that incorporates information received from third-party sources along with certain internal assumptions regarding the future performance. The Company's considerations include, but are not limited to (a) changes in the financial condition of the issuer and/or the underlying collateral, (b) whether the issuer is current on contractually obligated interest and principal payments, (c) credit ratings, (d) payment structure of the security and (e) the extent to which the fair value has been less than the amortized cost of the security. For non-structured securities, assumptions include, but are not limited to, economic and industry-specific trends and fundamentals, instrument-specific developments including changes in credit ratings, industry earnings multiples and the issuer’s ability to restructure, access capital markets, and execute asset sales. For structured securities, assumptions include, but are not limited to, various performance indicators such as historical and projected default and recovery rates, credit ratings, current and projected delinquency rates, loan-to-value ratios ("LTVs"), average cumulative collateral loss rates that vary by vintage year, prepayment speeds, and property value declines. These assumptions require the use of significant management judgment and include the probability of issuer default and estimates regarding timing and amount of expected recoveries which may include estimating the underlying collateral value.

Due to the potential for variability in payment speeds (i.e. prepayments or extensions), mortgage-backed and asset-backed securities are not categorized by contractual maturity. Concentration of Credit Risk The Company aims to maintain a diversified investment portfolio including issuer, sector and geographic stratification, where applicable, and has established certain exposure limits, diversification standards and review procedures to mitigate credit risk. The Company had no investment exposure to any credit concentration risk of a single issuer greater than 10% of the Company's stockholder's equity, other than the U.S. government and certain U.S. government agencies as of December 31, 2020 or 2019 (Successor Company). As of December 31, 2020 (Successor Company), other than U.S. government and certain U.S. government agencies, the Company’s three largest exposures by issuer were the IBM Corporation, Walt Disney Company, and Wells Fargo & Company, which each comprised less than 1% of total invested assets. As of December 31, 2019 (Successor Company), other than U.S. government and certain U.S. government agencies, the Company’s three largest exposures by issuer were the IBM Corporation, Walt Disney Company, and the Microsoft Corporation, which each comprised less than 1% of total invested assets. The Company’s three largest exposures by sector as of December 31, 2020 (Successor Company), were financial services, utilities, and the CLO sector which comprised approximately 8%, 8%, and 7%, respectively, of total invested assets. The Company’s three largest exposures by sector as of December 31, 2019 (Successor Company) were utilities, CMBS, and financial services which comprised approximately 7%, 7%, and 7%, respectively, of total invested assets.

As of December 31, 2020 (Successor Company), 99% of these fixed maturities were depressed less than 20% of cost or amortized cost. The increase in unrealized losses during 2020 was primarily attributable to wider credit spreads within higher yielding corporates and CMBS and higher interest rates on U.S. Treasuries purchased earlier in the year. Most of the fixed maturities depressed for twelve months or more relate to CLOs and corporates. CLO securities and corporate fixed maturities were primarily depressed because current market spreads are wider than at the respective purchase dates. The Company neither has an intention to sell nor does it expect to be required to sell the fixed maturities outlined in the preceding discussion. The decision to record credit losses on fixed maturities, AFS in the form of an ACL requires us to make qualitative and quantitative estimates of expected future cash flows. Actual cash flows could deviate significantly from our expectations resulting in realized losses in future periods. Mortgage Loans ACL on Mortgage Loans The Company reviews mortgage loans on a quarterly basis to estimate the ACL, with changes in the ACL recorded in net realized capital gains and losses. Apart from an ACL recorded on individual mortgage loans where the borrower is experiencing financial difficulties, the Company records an ACL on the pool of mortgage loans based on lifetime expected credit losses. The Company utilizes a third-party forecasting model to estimate lifetime expected credit losses at a loan level under multiple economic scenarios. The scenarios use macroeconomic data provided by an internationally recognized economics firm that generates forecasts of varying economic factors such as GDP growth, unemployment and interest rates. The economic scenarios are projected over 10 years. The first two to four years of the 10-year period assume a specific modeled economic scenario (including moderate upside, moderate recession and severe recession scenarios) and then revert to historical long-term assumptions over the remaining period. Using these economic scenarios, the forecasting model projects property-specific operating income and capitalization rates used to estimate the value of a future operating income stream. The operating income and the property valuations derived from capitalization rates are compared to loan payment and principal amounts to create debt-service coverage ratios ("DSCRs") and LTVs over the forecast period. The model overlays historical data about mortgage loan performance based on DSCRs and LTVs and projects the probability of default, amount of loss given a default and resulting expected loss through maturity for each loan under each economic scenario. Economic scenarios are probability-weighted based on a statistical analysis of the forecasted economic factors and qualitative analysis. The Company records the change in the ACL on mortgage loans based on the weighted-average expected credit losses across the selected economic scenarios. In response to significant economic stress experienced as a result of the COVID-19 pandemic during 2020 the Company increased the weight of both a moderate and severe recession in our estimate of the ACL. The Company continues to monitor economic uncertainty including rising COVID-19 infections leading to short-term lockdowns and the corresponding impact that this might have on the mortgage loan portfolio. The ultimate impact to the Company’s financial statements could vary significantly from our estimates depending on, among other things, the duration and severity of the pandemic, the duration and severity of the economic downturn and the degree to which federal, state and local government actions to mitigate the economic impact of COVID-19 are effective. The impact on our commercial mortgage loan portfolio will also be impacted by borrower behavior in response to the economic stress. Borrowers with lower LTVs have an incentive to continue to make payments of principal and/or interest in order to preserve the equity they have in the underlying commercial real estate properties. As property values decline, borrowers have less incentive to continue to make payments. When a borrower is experiencing financial difficulty, including when foreclosure is probable, the Company measures an ACL on individual mortgage loans.The ACL is established for any shortfall between the amortized cost of the loan and the fair value of the collateral less costs to sell. Estimates of collectibility from an individual borrower require the use of significant management judgment and include the probability and timing of borrower default and loss severity estimates. In addition, cash flow projections may change based upon new information about the borrower's ability to pay and/or the value of underlying collateral such as changes in projected property value estimates. As of December 31, 2020 (Successor Company), the Company did not have any mortgage loans for which an ACL was established on an individual basis. There were no mortgage loans held-for-sale as of December 31, 2020 or 2019 (Successor Company). As of December 31, 2020 (Successor Company), the Company had no mortgage loans that have had extensions or restructurings other than what is allowable under the original terms of the contract. Prior to January 1, 2020, the accounting model was based on an incurred loss approach. Mortgage loans were considered to be impaired when management estimated that, based upon current information and events, it was probable that the Company would be unable to collect amounts due according to the contractual terms of the loan agreement. For mortgage loans that were deemed impaired, a valuation allowance was established for the difference between the carrying amount and estimated value. Changes in valuation allowances were recorded in net realized capital gains and losses.

For further information, refer to Note 1 - Basis of Presentation and Significant Accounting Policies. [2] Prior to adoption of accounting guidance for credit losses on January 1, 2020, amounts were presented as a valuation allowance on mortgage loans. The increase in the allowance for the year-ended December 31, 2020 (Successor Company) is the result of the COVID-19 pandemic and its impacts on the economic forecasts, as discussed above, as well as lower estimated property values and operating income as compared to the prior year. The weighted-average LTV ratio of the Company’s mortgage loan portfolio was 54% as of December 31, 2020 (Successor Company), while the weighted-average LTV ratio at origination of these loans was 62%. LTV ratios compare the loan amount to the value of the underlying property collateralizing the loan with property values based on appraisals updated no less than annually. Factors considered in estimating property values include, among other things, actual and expected property cash flows, geographic market data and the ratio of the property's net operating income to its value. DSCR compares a property’s net operating income to the borrower’s principal and interest payments and are updated no less than annually through reviews of underlying properties.

Past-Due Mortgage Loans Mortgage loans are considered past due if a payment of principal or interest is not received according to the contractual terms of the loan agreement, which typically includes a grace period. As of December 31, 2020 and 2019 (Successor Company), the Company held no mortgage loans considered past due. Purchased Financial Assets with Credit Deterioration Purchased financial assets with credit deterioration ("PCD") are purchased financial assets with a “more-than-insignificant” amount of credit deterioration since origination. PCD assets are assessed only at initial acquisition date and for any investments identified, the Company records an allowance at acquisition with a corresponding increase to the amortized cost basis. As of December 31, 2020 (Successor Company), the Company held no PCD fixed maturities, AFS or mortgage loans. Variable Interest Entities The Company is engaged with various special purpose entities and other entities that are deemed to be variable interest entities ("VIEs") primarily as an investor through normal investment activities. A VIE is an entity that either has investors that lack certain essential characteristics of a controlling financial interest, such as simple majority kick-out rights, or lacks sufficient funds to finance its own activities without financial support provided by other entities. The Company performs ongoing qualitative assessments of its VIEs to determine whether the Company has a controlling financial interest in the VIE and therefore is the primary beneficiary. The Company is deemed to have a controlling financial interest when it has both the ability to direct the activities that most significantly impact the economic performance of the VIE and the obligation to absorb losses or right to receive benefits from the VIE that could potentially be significant to the VIE. Based on the Company’s assessment, if it determines it is the primary beneficiary, the Company consolidates the VIE on the Company’s Consolidated Financial Statements. As of December 31, 2020 and 2019 (Successor Company), the Company did not hold any VIEs for which it was the primary beneficiary. Non-Consolidated VIEs The Company, through normal investment activities, makes passive investments in limited partnerships and other alternative investments. For these non-consolidated VIEs, the Company has determined it is not the primary beneficiary as it has no ability to direct activities that could significantly affect the economic performance of the investments. The Company’s maximum exposure to loss as of December 31, 2020 and 2019 (Successor Company) is limited to the total carrying value of $975 and $914, respectively, which are included in limited partnerships and other alternative investments on the Company's Consolidated Balance Sheets. As of December 31, 2020 and 2019 (Successor Company), the Company had outstanding commitments totaling $461 and $474, respectively, whereby the Company is committed to fund these investments and may be called by the partnership during the commitment period to fund the purchase of new investments and partnership expenses. These investments are generally of a passive nature in that the Company does not take an active role in management. In addition, the Company also makes passive investments in structured securities issued by VIEs for which the Company is not the manager. These investments are included in ABS, CLOs, CMBS and RMBS in the Available-for-Sale Securities table on the Company’s Consolidated Balance Sheets. The Company has not provided financial or other support with respect to these investments other than its original investment. For these investments, the Company determined it is not the primary beneficiary due to the relative size of the Company’s investment in comparison to the principal amount of the structured securities issued by the VIEs, the level of credit subordination which reduces the Company’s obligation to absorb losses or right to receive benefits and the Company’s inability to direct the activities that most significantly impact the economic performance of the VIEs. The Company’s maximum exposure to loss on these investments is limited to the amount of the Company’s investment. Repurchase Agreements and Other Collateral Transactions The Company enters into securities financing transactions as a way to earn additional income or manage liquidity, primarily through repurchase agreements. Repurchase Agreements From time to time, the Company enters into repurchase agreements to manage liquidity or to earn incremental income. A repurchase agreement is a transaction in which one party (transferor) agrees to sell securities to another party (transferee) in return for cash (or securities), with a simultaneous agreement to repurchase the same securities at a specified price at a later date. The maturity of these transactions is generally of ninety days or less. Repurchase agreements include master netting provisions that provide both parties the right to offset claims and apply securities held by them with respect to their obligations in the event of a default. Although the Company has the contractual right to offset claims, the Company's current positions do not meet the specific conditions for net presentation. Under repurchase agreements, the Company transfers collateral of U.S. government and government agency securities and receives cash. For repurchase agreements, the Company obtains cash in an amount equal to at least 95% of the fair value of the securities transferred. The agreements require additional collateral to be transferred under specified conditions and provide the counterparty the right to sell or re-pledge the securities transferred. The cash received from the repurchase program is typically invested in short-term investments or fixed maturities and is reported as an asset on the Company's Consolidated Balance Sheets. The Company accounts for the repurchase agreements as collateralized borrowings. The securities transferred under repurchase agreements are included in fixed maturities, AFS with the obligation to repurchase those securities recorded in other liabilities on the Company's Consolidated Balance Sheets. From time to time, the Company enters into reverse repurchase agreements where the Company purchases securities and simultaneously agrees to resell the same or substantially the same securities. The maturity of these transactions is generally within one year. The agreements require additional collateral to be transferred to the Company under specified conditions and the Company has the right to sell or re-pledge the securities received. The Company accounts for reverse repurchase agreements as collateralized financing. The receivable for reverse repurchase agreements is included within short-term investments in the Company's Consolidated Balance Sheets.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities Disclosure [Text Block]	Derivative Instruments The Company utilizes a variety of OTC, OTC-cleared and exchange traded derivative instruments as a part of its overall risk management strategy as well as to enter into replication transactions. Derivative instruments are used to manage risk associated with interest rate, equity market, credit spread, issuer default, price, and currency exchange rate risk or volatility. Replication transactions are used as an economical means to synthetically replicate the characteristics and performance of assets that are permissible investments under the Company’s investment policies. The Company also may enter into and has previously issued financial instruments and products that either are accounted for as free-standing derivatives, such as certain reinsurance contracts, or as embedded derivative instruments, such as certain GMWB riders included with certain variable annuity products. Strategies that Qualify for Hedge Accounting Some of the Company's derivatives satisfy hedge accounting requirements as outlined in Note 1 of these financial statements. Typically, these hedging instruments include interest rate swaps and, to a lesser extent, foreign currency swaps where the terms or expected cash flows of the hedged item closely match the terms of the swap. The interest rate swaps are typically used to manage interest rate duration of certain fixed maturity securities or liability contracts. As a result of pushdown accounting, derivative instruments that previously qualified for hedge accounting were de-designated and recorded at fair value through adjustments to additional paid in capital at the acquisition date. The hedge strategies by hedge accounting designation include: Cash Flow Hedges Interest rate swaps are predominantly used to manage portfolio duration and better match cash receipts from assets with cash disbursements required to fund liabilities. These derivatives primarily convert interest receipts on floating-rate fixed maturity securities to fixed rates. Foreign currency swaps are used to convert foreign currency-denominated cash flows related to certain investment receipts and liability payments to U.S. dollars in order to reduce cash flow fluctuations due to changes in currency rates. Non-qualifying Strategies Derivative relationships that do not qualify for hedge accounting (“non-qualifying strategies”) primarily include the hedge program for the Company's variable annuity products as well as the hedging and replication strategies that utilize credit default swaps. In addition, hedges of interest rate, foreign currency and equity risk of certain fixed maturities, equities and liabilities do not qualify for hedge accounting. The non-qualifying strategies include: Interest Rate Swaps, Swaptions and Futures The Company uses interest rate swaps, swaptions and futures to manage interest rate duration between assets and liabilities in certain investment portfolios. In addition, the Company enters into interest rate swaps to terminate existing swaps, thereby offsetting the changes in value of the original swap. As of December 31, 2020 and 2019 (Successor Company), the notional amount of interest rate swaps in offsetting relationships was $1.3 billion for both years. Foreign Currency Swaps and Forwards The Company enters into foreign currency swaps to convert the foreign currency exposures of certain foreign currency-denominated fixed maturity investments to U.S. dollars. The Company also enters into foreign currency forwards to hedge non-U.S. dollar denominated cash. Fixed Payout Annuity Hedge The Company previously had obligations for certain yen denominated fixed payout annuities under an assumed reinsurance contract. The Company had in place swap contracts to hedge the currency and yen interest rate exposure between the U.S. dollar denominated assets and the yen denominated fixed liability reinsurance payments. The last swap matured on October 31, 2019. Credit Contracts Credit default swaps are used to purchase credit protection on an individual entity or referenced index to economically hedge against default risk and credit-related changes in the value of fixed maturity securities. Credit default swaps are also used to assume credit risk related to an individual entity or referenced index as a part of replication transactions. These contracts require the Company to pay or receive a periodic fee in exchange for compensation from the counterparty or the Company should the referenced security issuers experience a credit event, as defined in the contract. In addition, the Company enters into credit default swaps to terminate existing credit default swaps, thereby offsetting the changes in value of the original swap going forward. Equity Index Swaps and Options The Company enters into equity index options to hedge the impact of a decline in the equity markets on the investment portfolio. Macro Hedge Program The Company utilizes equity swaps, options and futures as well as interest rate swaps to provide protection against the statutory tail scenario risk to the Company's statutory surplus arising from higher GMWB and guaranteed minimum death benefits ("GMDB") claims as well as lower variable annuity fee revenue. GMWB Derivatives, net The Company formerly offered certain variable annuity products with GMWB riders. The GMWB product is a bifurcated embedded derivative (“GMWB product derivatives”) that has a notional value equal to the GRB. The Company uses reinsurance contracts to transfer a portion of its risk of loss due to GMWB. The reinsurance contracts covering GMWB (“GMWB reinsurance contracts”) are accounted for as free-standing derivatives with a notional amount equal to the GRB reinsured. During 2020, the Company closed the dynamic hedging program as the targeted risk exposure was no longer significant. Any risks covered previously under the dynamic hedging program are now covered by the macro hedge program. The Company previously utilized derivatives (“GMWB hedging instruments”) as part of a dynamic hedging program designed to hedge a portion of the capital market risk exposures of the non-reinsured GMWB riders. The GMWB hedging instruments hedged changes in interest rates, equity market levels, and equity volatility. These derivatives included customized swaps, interest rate swaps and futures, and equity swaps, options and futures, on certain indices including the S&P 500 index, EAFE index and NASDAQ index. The Company retained the risk for differences between assumed and actual policyholder behavior and between the performance of the actively managed funds underlying the separate accounts and their respective indices.

The assets are primarily held in a trust established by the Company. The Company pays or receives cash quarterly to settle the operating results of the reinsured business, including the investment results. As a result of this modified coinsurance arrangement, the Company has an embedded derivative that transfers to the reinsurer certain unrealized changes in fair value of investments subject to interest rate and credit risk. The notional amount of the embedded derivative reinsurance contracts are the invested assets which are carried at fair value and support the reinsured reserves. Derivative Balance Sheet Classification For reporting purposes, the Company has elected to offset within assets or liabilities based upon the net of the fair value amounts, income accruals, and related cash collateral receivables and payables of OTC derivative instruments executed in a legal entity and with the same counterparty under a master netting agreement, which provides the Company with the legal right of offset. The following fair value amounts do not include income accruals or related cash collateral receivables and payables, which are netted with derivative fair value amounts to determine balance sheet presentation. Derivatives in the Company’s separate accounts, where the associated gains and losses accrue directly to policyholders are not included in the table below. The Company’s derivative instruments are held for risk management purposes, unless otherwise noted in the following table. The notional amount of derivative contracts represents the basis upon which pay or receive amounts are calculated and is presented in the table to quantify the volume of the Company’s derivative activity. Notional amounts are not necessarily reflective of credit risk. The following tables exclude investments that contain an embedded credit derivative for which the Company has elected the fair value option.

Offsetting of Derivative Assets/Liabilities The following tables present the gross fair value amounts, the amounts offset, and net position of derivative instruments eligible for offset on the Company's Consolidated Balance Sheets. Amounts offset include fair value amounts, income accruals and related cash collateral receivables and payables associated with derivative instruments that are traded under a common master netting agreement, as described in the preceding discussion. Also included in the tables are financial collateral receivables and payables, which are contractually permitted to be offset upon an event of default, although are disallowed for offsetting under U.S. GAAP.

Cash Flow Hedges For derivative instruments that are designated and qualify as cash flow hedges, the gain or loss on the derivative is reported as a component of OCI and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. All components of each derivative’s gain or loss were included in the assessment of hedge effectiveness.

This expectation is based on the anticipated interest payments on hedged investments in fixed maturity securities that will occur over the next twelve months, at which time the Company will recognize the deferred net gains (losses) as an adjustment to net investment income over the term of the investment cash flows. For all periods presented, the Company had no net reclassifications from AOCI to earnings resulting from the discontinuance of cash-flow hedges due to forecasted transactions that were no longer probable of occurring. Non-qualifying Strategies For non-qualifying strategies, including embedded derivatives that are required to be bifurcated from their host contracts and accounted for as derivatives, the gain or loss on the derivative is recognized currently in earnings within net realized capital gains (losses).

Credit Risk Assumed through Credit Derivatives The Company enters into credit default swaps that assume credit risk of a single entity or referenced index in order to synthetically replicate investment transactions that are permissible under the Company's investment policies. The Company will receive periodic payments based on an agreed upon rate and notional amount and will only make a payment if there is a credit event. A credit event payment will typically be equal to the notional value of the swap contract less the value of the referenced security issuer’s debt obligation after the occurrence of the credit event. A credit event is generally defined as a default on contractually obligated interest or principal payments or bankruptcy of the referenced entity. The credit default swaps in which the Company assumes credit risk primarily reference investment grade single corporate issuers and baskets, which include standard diversified portfolios of corporate and CMBS issuers. The diversified portfolios of corporate issuers are established within sector concentration limits and may be divided into tranches that possess different credit ratings. As of December 31, 2020 and 2019 (Successor Company), the Company did not hold any credit derivatives that assume credit risk. Derivative Collateral Arrangements The Company enters into various collateral arrangements in connection with its derivative instruments, which require both the pledging and accepting of collateral. As of December 31, 2020 and 2019 (Successor Company), the Company pledged cash collateral with a fair value of $48 and $10, respectively, associated with derivative instruments. The collateral receivable has been recorded in other assets or other liabilities on the Company's Consolidated Balance Sheets, as determined by the Company's election to offset on the balance sheet. As of December 31, 2020 and 2019 (Successor Company), the Company also pledged securities collateral associated with derivative instruments with a fair value of $526 and $214, respectively, which have been included in fixed maturities on the Consolidated Balance Sheets. The counterparties generally have the right to sell or re-pledge these securities. In addition, as of December 31, 2020 and 2019 (Successor Company), the Company has pledged initial margin of securities related to OTC-cleared and exchange traded derivatives with a fair value of $215 and $165, respectively. As of December 31, 2020 and 2019 (Successor Company), the Company accepted cash collateral associated with derivative instruments of $65 and $188, respectively, which was invested and recorded on the Consolidated Balance Sheets in fixed maturities and short-term investments with corresponding amounts recorded in other investments or other liabilities as determined by the Company's election to offset on the balance sheet. The Company also accepted securities collateral as of December 31, 2020 and 2019 (Successor Company) with a fair value of $0 and $9, respectively, all of which the Company has the right to sell or repledge. As of December 31, 2020 (Successor Company), the Company has not repledged securities and did not sell any securities. The non-cash collateral accepted was held in separate custodial accounts and was not included on the Company's Consolidated Balance Sheets.

Reinsurance Disclosures [Abstract]
Reinsurance	The Company cedes insurance to unaffiliated insurers to enable the Company to manage capital and risk exposure. Such arrangements do not relieve the Company of its primary liability to policyholders. Failure of reinsurers to honor their obligations could result in losses to the Company. The Company regularly monitors the financial condition and ratings of its reinsurers and structures agreements to provide collateral funds where necessary. Reinsurance Recoverables Reinsurance recoverables include balances due from reinsurance companies and are presented net of allowances for uncollectible reinsurance in 2019 and net of ACL in 2020, upon adoption of ASU 2016-13. For further information, see Note 1 - Basis of Presentation and Significant Accounting Policies of Notes to Consolidated Financial Statements. The ACL represents an estimate of expected credit losses over the lifetime of the contracts that reflect management’s best estimate of reinsurance cessions that may be uncollectible in the future due to reinsurers’ inability to pay. Reinsurance recoverables include an estimate of the amount of policyholder benefits that may be ceded under the terms of the reinsurance agreements. Amounts recoverable from reinsurers are estimated in a manner consistent with assumptions used for the underlying policy benefits. Accordingly, the Company’s estimate of reinsurance recoverables is subject to similar risks and uncertainties as the estimate of the gross reserve for future policy benefits. Reinsurance Recoverables, net (Successor Company) As of December 31, 2020 2019 Reserve for future policy benefits and other policyholder funds and benefits payable Sold businesses (MassMutual and Prudential) $ 18,807 $ 19,534 Commonwealth 7,579 8,147 Other reinsurers 1,076 1,143 Gross reinsurance recoverables 27,462 28,824 Less: ACL 7 Reinsurance recoverables, net [1] $ 27,455 $ 28,824 [1] As of December 31, 2019 (Successor Company), no allowance for uncollectible reinsurance was required. As of December 31, 2020 (Successor Company), the Company had reinsurance recoverables from Commonwealth, Massachusetts Mutual Life Insurance Company ("MassMutual") and Prudential Financial, Inc. ("Prudential") of approximately $7.6 billion, $7.0 billion and $11.8 billion, respectively. As of December 31, 2019 (Successor Company), the Company had reinsurance recoverables from Commonwealth, MassMutual and Prudential of $8.1 billion, $8.0 billion and $11.5 billion, respectively. The Company's obligations to its direct policyholders that have been reinsured to Commonwealth, MassMutual and Prudential are primarily secured by invested assets held in trust. As of December 31, 2020 (Successor Company), the ACL increased to $7 from $5 at January 1, 2020, upon adoption of ASU 2016-13. The Company closely monitors the financial condition, ratings and current market information of all its counterparty reinsurers and records an ACL considering the credit quality of the reinsurer, the invested assets in trust, and the period over which the recoverable balances are expected to be collected. Counterparty risk is assessed on a pooled basis in cases of shared risk characteristics, and separately for individual reinsurers when it is more relevant. The Company evaluates historical events, current conditions, and reasonable and supportable forecasts in developing its ACL estimate. Where its contracts permit, the Company secures future claim obligations with various forms of collateral, including irrevocable letters of credit, secured trusts and funds held accounts. The ACL is estimated using a probability of default and loss given default model applied to the amount of reinsurance recoverables, net of collateral, exposed to loss. The probability of default factor is assigned based on each reinsurer's credit rating. The Company reassesses and updates credit ratings on a quarterly basis. The probability of default factors encompass historical industry defaults for liabilities with similar durations to the reinsured liabilities as estimated through multiple economic cycles. The loss given default factors are based on a study of historical recovery rates for general creditors of corporations through multiple economic cycles.

Insurance recoveries on ceded reinsurance agreements, which reduce death and other benefits, were $1.5 billion and $1.4 billion for the years ended December 31, 2020 and 2019 (Successor Company), respectively, $731 for the period of June 1, 2018 to December 31, 2018 (Successor Company) and $546 for the period of January 1, 2018 to May 31, 2018 (Predecessor Company). In addition, the Company has reinsured a portion of the risk associated with U.S. variable annuities and the associated GMDB and GMWB riders.

Debt	Collateralized Advances The Company is a member of the Federal Home Loan Bank of Boston (“FHLBB”). Membership allows the Company access to collateralized advances, which may be used to support various spread-based business and enhance liquidity management. FHLBB membership requires the Company to own member stock and advances require the purchase of activity stock. The amount of advances that can be taken are dependent on the asset types pledged to secure the advances. The Connecticut Insurance Department ("CTDOI") will permit the Company to pledge up to approximately $940 in qualifying assets to secure FHLBB advances for 2021. The pledge limit is recalculated annually based on statutory admitted assets and capital and surplus. The Company would need to seek the prior approval of the CTDOI in order to exceed these limits. As of December 31, 2020, the Company had no advances outstanding under the FHLBB facility.

The statute of limitations is closed through the 2016 tax year with the exception of net operating loss ("NOL") carryforwards utilized in open tax years. Management believes that adequate provision has been made on the consolidated financial statements for any potential adjustments that may result from tax examinations and other tax-related matters for all open tax years. For periods ending December 31, 2020 and 2019 (Successor Company), the Company had no reserves for uncertain tax positions. At December 31, 2020 and 2019 (Successor Company), there was no unrecognized tax benefit that if recognized would affect the effective tax rate and that is reasonably possible of significantly increasing or decreasing within the next 12 months. The Company classifies interest and penalties (if applicable) as income tax expense on the consolidated financial statements. The Company recognized no interest expense for the years ended December 31, 2020 and 2019 (Successor Company), the period of June 1, 2018 to December 31, 2018 (Successor Company) and the period of January 1, 2018 to May 31, 2018 (Predecessor Company). The Company had no interest payable as of December 31, 2020 and 2019 (Successor Company). The Company does not believe it would be subject to any penalties in any open tax years and, therefore, has not recorded any accrual for penalties. The application of purchase and pushdown accounting resulted in market value adjustments to the Company’s assets and liabilities, which resulted in a corresponding increase in the Company’s deferred tax asset. For further information, see Note 1- Basis of Presentation and Significant Accounting Policies of Notes to Consolidated Financial Statements. The Company believes it is more likely than not that all deferred tax assets will be fully realized. In assessing the need for a valuation allowance, management considered future taxable temporary difference reversals, future taxable income exclusive of reversing temporary differences and carryovers, taxable income in open carry back years and other tax planning strategies. From time to time, tax planning strategies could include holding a portion of debt securities with market value losses until recovery, making investments which have specific tax characteristics and business considerations such as asset-liability matching. Net deferred income taxes include the future tax benefits associated with the net operating loss carryover and foreign tax credit carryover as follows: Net Operating Loss Carryover As of December 31, 2020 and 2019 (Successor Company), the net deferred tax asset included the expected tax benefit attributable to net operating losses of $484 and $790, respectively. The totals include U.S. losses that were generated prior to 2017 of $121 and $437, respectively. These losses are subject to limits on the period for which they can be carried forward. If not utilized, these losses will expire from 2028-2030. Utilization of these loss carryovers is dependent upon the generation of sufficient future taxable income. The totals also include U.S. losses that were generated in 2018 of $363 and $353, respectively, primarily due to the Commonwealth Annuity Reinsurance Agreement. These losses do not expire, but their utilization in any carryforward year is limited to 80% of taxable income in that year. Given the continued decline of the U.S. fixed and variable annuity business, the exposure to taxable losses is significantly lessened, and given the Company's expected future earnings, the Company believes sufficient taxable income will be generated in the future to utilize its net operating loss carryover. Although the Company believes there will be sufficient future taxable income to fully recover the remainder of the loss carryover, the Company's estimate of the likely realization may change over time. Foreign Tax Credit Carryover As of December 31, 2020 and 2019 (Successor Company), the net deferred tax asset included the expected tax benefit attributable to foreign tax credit carryovers of $18 and $13 respectively.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Contingencies Relating to Corporate Litigation and Regulatory Matters Management evaluates each contingent matter separately. A loss is recorded if probable and reasonably estimable. Management establishes reserves for these contingencies at its “best estimate,” or, if no one number within the range of possible losses is more probable than any other, the Company records an estimated liability at the low end of the range of losses. Litigation The Company is involved in claims litigation arising in the ordinary course of business with respect to life and annuity contracts. The Company accounts for such activity through the establishment of reserves for future policy benefits. Management expects that the ultimate liability, if any, with respect to such ordinary-course claims litigation, after consideration of provisions made for potential losses and costs of defense, will not be material to the consolidated financial condition, results of operations or cash flows of the Company. The Company is also involved in other kinds of legal actions, some of which assert claims for substantial amounts. Such actions have alleged, for example, bad faith in the handling of insurance claims and improper sales practices in connection with the sale of insurance and investment products. Some of these actions also seek punitive damages. Management expects that the ultimate liability, if any, with respect to such lawsuits, after consideration of provisions made for estimated losses, will not be material to the consolidated financial condition of the Company. Nonetheless, given the large or indeterminate amounts sought in certain of these actions, and the inherent unpredictability of litigation, it is possible that an adverse outcome in certain matters could, from time to time, have a material adverse effect on the Company’s consolidated financial condition, results of operations or cash flows in particular quarterly or annual periods. Lease Commitments The rent paid to Hartford Fire Insurance Company ("Hartford Fire") for operating leases was $2 and $2 for the years ended December 31, 2020 and 2019, respectively (Successor Company), $1 for the period of June 1, 2018 to December 31, 2018 (Successor Company) and $1 for the period of January 1, 2018 to May 31, 2018 (Predecessor Company). Future Minimum Lease Payments (Successor Company) 2021 $ 1 2022 1 2023 1 2024 — 2025 — Thereafter — Total minimum lease payments $ 3 Unfunded Commitments As of December 31, 2020 (Successor Company), the Company had outstanding commitments totaling $567, of which $463 was committed to fund limited partnership and other alternative investments, which may be called by the partnership during the commitment period to fund the purchase of new investments and partnership expenses. Additionally, $4 of the outstanding commitments is primarily related to various funding obligations associated with private debt securities. The remaining outstanding commitments of $100 relate to mortgage loans. Of the $567 in total outstanding commitments, $66 are related to mortgage loan commitments which the Company can cancel unconditionally. Guaranty Fund and Other Insurance-related Assessments In all states, insurers licensed to transact certain classes of insurance are required to become members of a guaranty fund. In most states, in the event of the insolvency of an insurer writing any such class of insurance in the state, members of the funds are assessed to pay certain claims of the insolvent insurer. A particular state’s fund assesses its members based on their respective written premiums in the state for the classes of insurance in which the insolvent insurer was engaged. Assessments are generally limited for any year to one or two percent of premiums written per year depending on the state. Derivative Commitments Certain of the Company’s derivative agreements contain provisions that are tied to the financial strength ratings, as set by nationally recognized statistical agencies or risked-based capital ("RBC") tests, of the individual legal entity that entered into the derivative agreement. If the legal entity’s financial strength were to fall below certain ratings, the counterparties to the derivative agreements could demand immediate and ongoing full collateralization and in certain instances enable the counterparties to terminate the agreements and demand immediate settlement of all outstanding derivative positions traded under each impacted bilateral agreement. The settlement amount is determined by netting the derivative positions transacted under each agreement. If the termination rights were to be exercised by the counterparties, it could impact the legal entity’s ability to conduct hedging activities by increasing the associated costs and decreasing the willingness of counterparties to transact with the legal entity. The aggregate fair value of all derivative instruments with credit-risk-related contingent features that are in a net liability position as of December 31, 2020 (Successor Company) was $539. Of this $539, the legal entities have posted collateral of $572, which is inclusive of initial margin requirements in the normal course of business. In addition, the Company has posted collateral of $23 associated with a customized GMWB derivative. These collateral amounts could change as derivative market values change, as a result of changes in our hedging activities or to the extent changes in contractual terms are negotiated. The nature of the collateral that we post, when required, would be primarily in the form of U.S. Treasury bills, U.S. Treasury notes and government agency securities.

Insurance [Abstract]
Insurance Disclosure [Text Block]	The domestic insurance subsidiaries of the Company prepare their statutory financial statements in conformity with statutory accounting practices prescribed or permitted by the applicable state insurance department which vary materially from U.S. GAAP. Prescribed statutory accounting practices include publications of the National Association of Insurance Commissioners (“NAIC”), as well as state laws, regulations and general administrative rules. The differences between statutory financial statements and financial statements prepared in accordance with U.S. GAAP vary between domestic and foreign jurisdictions. The principal differences are that statutory financial statements do not reflect deferred policy acquisition and value of business acquired costs and limit deferred income taxes, predominately use interest rate and mortality assumptions prescribed by the NAIC for life benefit reserves, generally carry bonds at amortized cost and present reinsurance assets and liabilities net of reinsurance. For reporting purposes, statutory capital and surplus is referred to collectively as "statutory capital". Statutory Net Income (Loss) Successor Company Predecessor Company For the Years Ended December 31, June 1, 2018 to December 31, 2018 January 1, 2018 to May 31, 2018 2020 2019 Combined statutory net income (loss) $ 245 $ 488 $ (126) $ 181 Statutory Capital Successor Company As of December 31, 2020 2019 Statutory capital [1] $ 3,142 $ 3,194 [1] The Company relies upon a prescribed practice allowed by Connecticut state laws that allow the Company to receive a reinsurance reserve credit for reinsurance treaties that provide for a limited right of unilateral cancellation by the reinsurer. The benefit from this prescribed practice was approximately $51 and $37 as of December 31, 2020 and 2019 (Successor Company), respectively. Statutory accounting practices do not consolidate the net income (loss) of subsidiaries that report under U.S. GAAP. The combined statutory net income (loss) above represents the total statutory net income (loss) of the Company and its other insurance subsidiaries. Regulatory Capital Requirements The Company's U.S. insurance companies' states of domicile impose RBC requirements. The requirements provide a means of measuring the minimum amount of statutory capital appropriate for an insurance company to support its overall business operations based on its size and risk profile. Regulatory compliance is determined by a ratio of a company's total adjusted capital (“TAC”) to its authorized control level RBC (“ACL RBC”). Companies below specific trigger points or ratios are classified within certain levels, each of which requires specified corrective action. The minimum level of TAC before corrective action commences (“Company Action Level”) is two times the ACL RBC. The adequacy of a company's capital is determined by the ratio of a company's TAC to its Company Action Level, known as the "RBC ratio". The Company and all of its operating insurance subsidiaries had RBC ratios in excess of the minimum levels required by the applicable insurance regulations. The RBC ratios for the Company and its principal life insurance operating subsidiaries were all in excess of 300% of their Company Action Levels as of December 31, 2020 and 2019 (Successor Company). The reporting of RBC ratios is not intended for the purpose of ranking any insurance company, or for use in connection with any marketing, advertising or promotional activities. Dividends Dividends to the Company from its insurance subsidiaries and dividends from the Company to its parent are restricted by insurance regulation. The payment of dividends by Connecticut-domiciled insurers is limited under the insurance holding company laws of Connecticut. These laws require notice to and approval by the state insurance commissioner for the declaration or payment of any dividend, which, together with other dividends or distributions made within the preceding twelve months, exceeds the greater of (i) 10% of the insurer’s policyholder surplus as of December 31 of the preceding year or (ii) net income (or net gain from operations, if such company is a life insurance company) for the twelve-month period ending on the thirty-first day of December last preceding, in each case determined under statutory insurance accounting principles. In addition, if any dividend of a domiciled insurer exceeds the insurer’s earned surplus or certain other thresholds as calculated under applicable state insurance law, the dividend requires the prior approval of the domestic regulator. In addition to statutory limitations on paying dividends, the Company also takes other items into consideration when determining dividends from subsidiaries. These considerations include, but are not limited to, expected earnings and capitalization of the subsidiary, regulatory capital requirements and liquidity requirements of the individual operating company. As a condition of the sale, Talcott Resolution Life Insurance Company and its affiliates were required to gain pre-approval from the state insurance commissioner for any dividends, regardless of size, through May 31, 2020. On September 18, 2020 (Successor Company), TL received a $400 dividend from its subsidiary, Talcott Resolution Life and Annuity Insurance Company ("TLA"). On the same date, TL subsequently declared and paid a $319 dividend to its parent, Talcott Resolution Life, Inc. ("TLI"). On September 16, 2019 (Successor Company), TL received a $250 dividend from its subsidiary, TLA. On the same date, TL subsequently declared and paid a $700 dividend to its parent, TLI. Prior to the close of the Talcott Resolution Sale Transaction, the Hartford Life Insurance Company (Predecessor Company) paid approximately $619 in dividends to its parent and subsequently to The Hartford. TL, formerly known as Hartford Life Insurance Company, contributed $309 and TLA, formerly known as Hartford Life and Annuity Insurance Company, contributed $308 including other intercompany transactions net settled between TL and The Hartford prior to closing. After September 18, 2021, the Company is permitted to pay up to a maximum of $597 in dividends and the Company's subsidiaries are permitted to pay up to a maximum of $335 in dividends without prior approval from the state insurance commissioner.

Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Basis of Presentation Talcott Resolution Life Insurance Company, formerly Hartford Life Insurance Company, (together with its subsidiaries, “TL,” “Company,” “we” or “our”) is a provider of insurance and investment products in the United States (“U.S.”) and is a wholly-owned subsidiary of Talcott Resolution Life, Inc., a Delaware corporation ("TLI"). Hopmeadow Holdings LP (“Hopmeadow Holdings", or "HHLP ”) is the ultimate parent of the Company. The Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”), which differ materially from the accounting practices prescribed by various insurance regulatory authorities. On May 31, 2018 the Company's indirect parent, Hartford Holding, Inc. ("HHI") completed the sale of the Company's parent to a group of investors led by Cornell Capital LLC, Atlas Merchant Capital LLC, TRB Advisors LP, Global Atlantic Financial Group ("Global Atlantic"), Pine Brook and J. Safra Group. Although Talcott Resolution Life Insurance Company is no longer affiliated with The Hartford Financial Services Group, Inc. ("The Hartford") or any of its subsidiaries, The Hartford retained a 9.7 percent ownership interest in HHLP ("Talcott Resolution Sale Transaction"). In conjunction with the sale, the Company entered into a transition services agreement with The Hartford for a period up to three years to provide general ledger, cash management, and information technology infrastructure services. In 2020, the transition services agreement was completed as all supported services have fully transitioned to the Company. In March, 2019, a five year administrative services agreement was entered into for investment accounting services which replaced the services previously provided under the transition services agreement. HHLP’s May 31, 2018 acquisition of TLI was accounted for by HHLP using business combination accounting. Under this method, the purchase price paid by the investor group was assigned to the identifiable assets acquired and liabilities assumed as of the acquisition date based on their fair value. The Company elected to apply "pushdown" accounting by applying the guidance permitted under Accounting Standards Codification (“ASC”) Topic 805 Business Combinations . By the application of pushdown accounting, the Company’s assets, liabilities and equity were accordingly adjusted to fair value on May 31, 2018 which generated both intangible assets and Value of Business Acquired (“VOBA”). Determining the fair value of certain assets acquired and liabilities assumed is judgmental in nature and often involves the use of significant estimates and assumptions. Due to the application of pushdown accounting, TL’s financial statements and footnote disclosures are presented in two distinct periods to indicate the application of two different bases of accounting. The periods prior to June 1, 2018 are identified herein as “Predecessor,” while the periods subsequent to HHLP’s acquisition of TLI are identified as “Successor.” As a result of the change in the basis of accounting from historical GAAP to reflect HHLP’s purchase cost, the financial statements for the Predecessor period are not comparable to the Successor periods.
Pushdown Accounting [Policy Text Block]	HHLP’s May 31, 2018 acquisition of TLI was accounted for by HHLP using business combination accounting. Under this method, the purchase price paid by the investor group was assigned to the identifiable assets acquired and liabilities assumed as of the acquisition date based on their fair value.

Consolidation	Consolidation The Consolidated Financial Statements include the accounts of TL and entities the Company directly or indirectly has a controlling financial interest in which the Company is required to consolidate. Entities in which TL has significant influence over the operating and financing decisions but is not required to consolidate are reported using the equity method. All intercompany transactions and balances between TL and its subsidiaries have been eliminated.
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 the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates.
Reclassification	Reclassifications Certain reclassifications have been made to prior year financial information to conform to the current year presentation.
New Accounting Pronouncements, Policy [Policy Text Block]	Adoption of New Accounting Standards Reclassification of Effect of Tax Rate Change from AOCI to Retained Earnings In February 2018, the FASB issued new accounting guidance for the effect on deferred tax assets and liabilities related to items recorded in AOCI resulting from legislated tax reform enacted on December 22, 2017. The tax reform reduced the federal tax rate applied to the Company’s deferred tax balances from 35% to 21% on enactment. Under U.S. GAAP, the Company recorded the total effect of the change in enacted tax rates on deferred tax balances as a charge to income tax expense within net income, including the change in deferred tax balances related to components of AOCI. The new accounting guidance permitted the Company to reclassify the “stranded” tax effects out of AOCI and into retained earnings that resulted from recording the tax effects of unrealized investment gains at a 35% tax rate because the 14 point reduction in tax rate was recognized in net income instead of other comprehensive income. On January 1, 2018, the Company (Predecessor Company) adopted the new guidance and recorded a reclassification of $193 which increased AOCI and reduced retained earnings. Financial Instruments - Recognition and Measurement On January 1, 2018, the Company (Predecessor Company) adopted updated guidance issued by the FASB for the recognition and measurement of financial instruments through a cumulative effect adjustment to the opening balances of retained earnings and AOCI. The new guidance requires investments in equity securities to be measured at fair value with any changes in valuation reported in net income except for investments that are consolidated or are accounted for under the equity method of accounting. The new guidance also requires a deferred tax asset resulting from net unrealized losses on available-for-sale fixed maturities that are recognized in AOCI to be evaluated for recoverability in combination with the Company’s other deferred tax assets. Under prior guidance, the Company reported equity securities, available for sale ("AFS"), at fair value with changes in fair value reported in other comprehensive income. As of January 1, 2018, the Company (Predecessor Company) reclassified from AOCI to retained earnings net unrealized gains of $11, after tax, related to equity securities having a fair value of $154. Beginning in 2018, the Company reports equity securities at fair value with changes in fair value reported in net realized capital gains and losses. Revenue Recognition On January 1, 2018, the Company (Predecessor Company) adopted the FASB’s updated guidance for recognizing revenue from contracts with customers, which excludes insurance contracts and financial instruments. Revenue subject to the guidance is recognized when, or as, goods or services are transferred to customers in an amount that reflects the consideration that an entity is expected to receive in exchange for those goods or services. The updated guidance is consistent with previous guidance for the Company’s transactions and did not have an effect on the Company’s financial position, cash flows or net income. Revenue from customers for other than insurance and investment contracts was $80 and $84 for the years ended December 31, 2020 and 2019, respectively (Successor Company), $54 for the period of June 1, 2018 to December 31, 2018 (Successor Company) and $40 for the period of January 1, 2018 to May 31, 2018 (Predecessor Company). The Company earns revenues from these contracts primarily for administrative and distribution services fees from offering certain fund families as investment options in its variable annuity products. Fees are primarily based on the average daily net asset values of the funds and are recorded in the period in which the services are provided and collected monthly. Fluctuations in domestic and international markets and related investment performance, volume and mix of sales and redemptions of the funds, and other changes to the composition of assets under management are all factors that ultimately have a direct effect on fee income earned. Hedging Activities The FASB issued updated guidance on hedge accounting. The updates allow hedge accounting for new types of interest rate hedges of financial instruments and simplify documentation requirements to qualify for hedge accounting. In addition, any gain or loss from hedge ineffectiveness will be reported in the same income statement line with the effective hedge results and the hedged transaction. For cash flow hedges, the ineffectiveness will be recognized in earnings only when the hedged transaction affects earnings; otherwise, the ineffectiveness gains or losses will remain in AOCI. Under previous accounting, total hedge ineffectiveness was reported separately in realized gains and losses apart from the hedged transaction. The updated guidance was effective January 1, 2019 through a cumulative effect adjustment that will reclassify cumulative ineffectiveness on open cash flow hedges from retained earnings to AOCI. As a result of pushdown accounting, derivative instruments that qualified for hedge accounting were recorded at fair value through adjustments to additional paid in capital at the acquisition date. As of December 31, 2018 (Successor Company), the Company had no derivative instruments that qualify for hedge accounting, therefore there was no impact on the Company's financial statements upon adoption. Changes to the Disclosure Requirements for Fair Value Measurement On August 28, 2018 the FASB issued Accounting Standards Update ("ASU") 2018-13 which removes, modifies and adds certain disclosure requirements related to fair value measurements in ASC 820, Fair Value Measurements . As permitted by the guidance, the Company early adopted amendments in this guidance effective December 31, 2019. The adoption of ASU 2018-13 did not have a material impact on the Company's consolidated financial statements. Financial Instruments - Credit Losses On January 1, 2020 the Company adopted ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments, ("ASU 2016-13", or "CECL") together with related updated guidance for recognition and measurement of credit losses on certain financial instruments not carried at fair value, including reinsurance recoverables. This guidance replaces the “incurred loss” approach with an “expected loss” model for recognizing credit losses for instruments carried at amortized cost, which resulted in the recognition of greater allowances for losses. Under the new model, an allowance for credit losses ("ACL") is recognized as an estimate of credit losses expected over the life of financial instruments, such as mortgage loans, reinsurance recoverables and off-balance sheet credit exposures that the Company cannot unconditionally cancel. The measurement of the expected credit loss estimate is based on historical loss data, current conditions, and reasonable and supportable forecasts. Credit losses on fixed maturities, AFS carried at fair value continue to be measured similar to previous guidance for other-than-temporary impairments ("OTTI"); however, losses are now recognized through the ACL and no longer as an adjustment to the amortized cost. Recoveries of OTTI on fixed maturities, AFS are recognized as reversals of the ACL recognized through net realized capital gains and losses and no longer accreted as net investment income through an adjustment to the investment yield. For fixed maturities, AFS this guidance is applied prospectively. Additionally, the new guidance requires purchased financial assets with a more-than-insignificant amount of credit deterioration since original issuance to establish an ACL at acquisition, which is recorded with the purchase price to establish the initial amortized cost of the investment. The Company adopted the guidance through a cumulative-effect adjustment that decreased retained earnings by $11, after tax, primarily related to the Company's mortgage loan investments. No ACL was recognized at adoption for fixed maturities, AFS as those provisions of the guidance are applied prospectively. Upon adoption, the Company did not have any purchased financial assets with a more-than-insignificant amount of credit deterioration since original issuance. Summary of Adoption Impacts ACL on mortgage loans $ (9) ACL on reinsurance recoverables (5) Deferred income tax asset 3 Net decrease to retained earnings $ (11) Future Adoption of New Accounting Standards Targeted Improvements to the Accounting for Long Duration Contracts The FASB issued ASU 2018-12 on August 15, 2018 which impacts the existing recognition, measurement, presentation and disclosure requirements for certain long duration contracts issued by an insurance company. The guidance is intended to improve the timeliness of recognizing changes in the liability for future policy benefits by requiring annual or more frequent updates of insurance assumptions and modifying the rate used to discount future cash flows. Cash flows under the new guidance are required to be discounted using an upper-medium grade fixed income instrument yield. The discount rate is required to be updated at each reporting date, with the effect of discount rate changes on the liability recorded in OCI. This is a change from current GAAP which utilizes assumptions, including discount rate, "locked in" at policy issuance and until such time significant changes in experience or assumptions may require the Company to establish premium deficiency reserves. When this occurs, premium deficiency reserves are recognized by unlocking reserve assumptions to eliminate a reserve deficiency under current GAAP. Further, the guidance seeks to improve the accounting for certain market-based options or guarantees associated with account balance contracts and improve the effectiveness of the required disclosures. These market risk benefit features are required to be measured at fair value with changes in fair value recorded in net income with the exception of changes in the fair value attributable to a change in the instrument's credit risk, which are required to be recognized in OCI. Additionally, this ASU requires new disclosures including liability rollforwards and information about significant inputs, judgments, assumptions, and methods used in the measurement. This guidance was amended through the issuance of ASU 2020-11, which deferred the effective date the Company is required to adopt the guidance to January 1, 2023, with early adoption permitted. The Company continues to assess its policies, processes, and applicable systems to determine the impact this standard will have on its operations and financial results. While it is not possible to reasonably estimate the expected impact of adoption at this time, given the nature and extent of the required changes to a significant portion of the Company’s operations, adoption is expected to have a material impact on our consolidated financial statements and related disclosures. This guidance represents a significant change from existing GAAP; however, it does not change the underlying economics of the business or its related cash flows.
Segment Information	Segment Information The Company has no reportable segments and its principal products and services are comprised of variable annuities, fixed and payout annuities, and private-placement life insurance. The Company's determination that it has no reportable segments is based on the fact that the Company's chief operating decision maker reviews the Company's financial performance at a consolidated level.
Revenue Recognition	Revenue Recognition For investment and universal life-type contracts, the amounts collected from policyholders are considered deposits and are not included in revenue. Fee income for variable annuity and other universal life-type contracts consists of policy charges for policy administration, cost of insurance charges and surrender charges assessed against policyholders’ account balances and are recognized in the period in which services are provided. For the Company’s traditional life products, premiums are recognized as revenue when due from policyholders.
Income Taxes	Income Taxes The Company recognizes taxes payable or refundable for the current year and deferred taxes for the tax consequences of temporary differences between the financial reporting and tax basis of assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years the temporary differences are expected to reverse. A deferred tax provision is recorded for the tax effects of differences between the Company's current taxable income and its income before tax under generally accepted accounting principles in the Consolidated Statements of Operations. For deferred tax assets, the Company records a valuation allowance that is adequate to reduce the total deferred tax asset to an amount that will more likely than not be realized.
Investments	Investments Overview The Company’s investments in fixed maturities include bonds, structured securities, redeemable preferred stock and commercial paper. Most of these investments are classified as AFS and are carried at fair value, net of ACL, in accordance with new guidance adopted January 1, 2020 regarding expected credit losses. The after-tax difference between fair value and cost or amortized cost is reflected in stockholder's equity as a component of AOCI, after adjustments for the effect of VOBA (Successor Company) and reserve adjustments. Equity securities are measured at fair value with any changes in valuation reported in net income. For further information, see Financial Instruments - Recognition and Measurement discussion above. Policy loans are carried at outstanding balance. Mortgage loans are recorded at the outstanding principal balance adjusted for amortization of premiums or discounts and net of ACL. Short-term investments are carried at amortized cost, which approximates fair value. Limited partnerships and other alternative investments are reported at their carrying value and are primarily accounted for under the equity method with the Company’s share of earnings included in net investment income. Recognition of income related to limited partnerships and other alternative investments is delayed due to the availability of the related financial information, as private equity and other funds are generally on a three-month lag and hedge funds on a one-month lag. Accordingly, income for the years ended December 31, 2020 and 2019 (Successor Company), the period of June 1, 2018 to December 31, 2018 (Successor Company) and and the period of January 1, 2018 to May 31, 2018 (Predecessor Company) may not include the full impact of current year changes in valuation of the underlying assets and liabilities of the funds, which are generally obtained from the limited partnerships and other alternative investments’ general partners. Other investments consist of derivative instruments which are carried at fair value and real estate acquired in satisfaction of debt. Net Realized Capital Gains and Losses Net realized capital gains and losses from investment sales are reported as a component of revenues and are determined on a specific identification basis. Net realized capital gains and losses also result from fair value changes in equity securities and derivatives contracts (both free-standing and embedded) that do not qualify, or are not designated, as a hedge for accounting purposes. Impairments and changes in the ACL on fixed maturities, AFS; mortgage loans; and reinsurance recoverables are recognized as net realized capital losses in accordance with the Company’s impairment and ACL policies as discussed in Note 3 - Investments of Notes to Consolidated Financial Statements. Foreign currency transaction remeasurements are also included in net realized capital gains and losses.
Derivatives	Derivative Instruments Overview The Company utilizes a variety of over-the-counter ("OTC") transactions cleared through central clearing houses ("OTC-cleared") and exchange traded derivative instruments as part of its overall risk management strategy as well as to enter into replication transactions. The types of instruments may include swaps, caps, floors, forwards, futures and options to achieve one of four Company-approved objectives: • to hedge risk arising from interest rate, equity market, commodity market, credit spread and issuer default, price or currency exchange rate risk or volatility; • to manage liquidity; • to control transaction costs; • to enter into synthetic replication transactions. Interest rate and credit default swaps involve the periodic exchange of cash flows with other parties, at specified intervals, calculated using agreed upon rates or other financial variables and notional principal amounts. Generally, little to no cash or principal payments are exchanged at the inception of the contract. Typically, at the time a swap is entered into, the cash flow streams exchanged by the counterparties are equal in value. Interest rate cap and floor contracts entitle the purchaser to receive from the issuer at specified dates, the amount, if any, by which a specified market rate exceeds the cap strike interest rate or falls below the floor strike interest rate, applied to a notional principal amount. A premium payment determined at inception is made by the purchaser of the contract and no principal payments are exchanged. Forward contracts are customized commitments that specify a rate of interest or currency exchange rate to be paid or received on an obligation beginning on a future start date and are typically settled in cash. Financial futures are standardized commitments to either purchase or sell designated financial instruments, at a future date, for a specified price and may be settled in cash or through delivery of the underlying instrument. Futures contracts trade on organized exchanges. Margin requirements for futures are met by pledging securities or cash, and changes in the futures’ contract values are settled daily in cash. Option contracts grant the purchaser, for a premium payment, the right to either purchase from or sell to the issuer a financial instrument at a specified price, within a specified period or on a stated date. The contracts may reference commodities, which grant the purchaser the right to either purchase from or sell to the issuer commodities at a specified price, within a specified period or on a stated date. Option contracts are typically settled in cash. Foreign currency swaps exchange an initial principal amount in two currencies, agreeing to re-exchange the currencies at a future date, at an agreed upon exchange rate. There may also be a periodic exchange of payments at specified intervals calculated using the agreed upon rates and exchanged principal amounts. The Company’s derivative transactions conducted in insurance company subsidiaries are used in strategies permitted under the derivative use plans required by the State of Connecticut and the State of New York insurance departments. Accounting and Financial Statement Presentation of Derivative Instruments and Hedging Activities Derivative instruments are recognized on the Consolidated Balance Sheets at fair value and are reported in Other Investments and Other Liabilities. For balance sheet presentation purposes, the Company has elected to offset the fair value amounts, income accruals, and related cash collateral receivables and payables of OTC derivative instruments executed in a legal entity and with the same counterparty or under a master netting agreement, which provides the Company with the legal right of offset. The Company clears certain interest rate swap and credit default swap derivative transactions through central clearing houses. OTC-cleared derivatives require initial collateral at the inception of the trade in the form of cash or highly liquid securities, such as U.S. Treasuries and government agency investments. Central clearing houses also require additional cash as variation margin based on daily market value movements. For information on collateral, see the derivative collateral arrangements section in Note 4 - Derivative Instruments of Notes to Consolidated Financial Statements. In addition, OTC-cleared transactions include price alignment amounts either received or paid on the variation margin, which are reflected in realized capital gains and losses or, if characterized as interest, in net investment income. On the date the derivative contract is entered into, the Company designates the derivative as (1) a hedge of the variability in cash flows of a forecasted transaction or of amounts to be received or paid related to a recognized asset or liability (“cash flow” hedge), (2) a hedge of a net investment in a foreign operation (“net investment” hedge) or (3) held for other investment and/or risk management purposes, which primarily involve managing asset or liability related risks and do not qualify for hedge accounting. Cash Flow Hedges - Changes in the fair value of a derivative that is designated and qualifies as a cash flow hedge, including foreign-currency cash flow hedges, are recorded in AOCI and are reclassified into earnings when the variability of the cash flow of the hedged item impacts earnings. Gains and losses on derivative contracts that are reclassified from AOCI to current period earnings are included in the line item in the Consolidated Statements of Operations in which the cash flows of the hedged item are recorded. For periods prior to 2019, hedge ineffectiveness was recorded immediately in current period earnings as net realized capital gains and losses. With the January 1, 2019 adoption of the updated FASB hedging guidance, ineffectiveness is recognized in earnings only when the hedged transaction affects earnings; otherwise, the ineffectiveness gains and losses remain in AOCI. Periodic derivative net coupon settlements are recorded in the line item of the Consolidated Statements of Operations in which the cash flows of the hedged item are recorded. Cash flows from cash flow hedges are presented in the same category as the cash flows from the items being hedged on the Consolidated Statements of Cash Flows. Other Investment and/or Risk Management Activities - The Company’s other investment and/or risk management activities primarily relate to strategies used to reduce economic risk or replicate permitted investments and do not receive hedge accounting treatment. Changes in the fair value, including periodic derivative net coupon settlements, of derivative instruments held for other investment and/or risk management purposes are reported in current period earnings as net realized capital gains and losses. Hedge Documentation and Effectiveness Testing To qualify for hedge accounting treatment, a derivative must be highly effective in mitigating the designated changes in fair value or cash flow of the hedged item. At hedge inception, the Company formally documents all relationships between hedging instruments and hedged items, as well as its risk-management objective and strategy for undertaking each hedge transaction. The documentation process includes linking derivatives that are designated as fair value, cash flow, or net investment hedges to specific assets or liabilities on the balance sheet or to specific forecasted transactions and defining the effectiveness testing methods to be used. The Company also formally assesses both at the hedge’s inception and ongoing on a quarterly basis, whether the derivatives that are used in hedging transactions have been and are expected to continue to be highly effective in offsetting changes in fair values, cash flows or net investment in foreign operations of hedged items. Hedge effectiveness is assessed primarily using quantitative methods as well as using qualitative methods. Quantitative methods include regression or other statistical analysis of changes in fair value or cash flows associated with the hedge relationship. Qualitative methods may include comparison of critical terms of the derivative to the hedged item. Discontinuance of Hedge Accounting The Company discontinues hedge accounting prospectively when (1) it is determined that the qualifying criteria are no longer met; (2) the derivative is no longer designated as a hedging instrument; or (3) the derivative expires or is sold, terminated or exercised. When cash flow hedge accounting is discontinued because the Company becomes aware that it is not probable that the forecasted transaction will occur, the derivative continues to be carried on the balance sheet at its fair value, and gains and losses that were accumulated in AOCI are recognized immediately in earnings. In other situations in which hedge accounting is discontinued, including those where the derivative is sold, terminated or exercised, amounts previously deferred in AOCI are reclassified into earnings when earnings are impacted by the hedged item. Embedded Derivatives The Company purchases investments and has previously issued financial products that contain embedded derivative instruments. When it is determined that (1) the embedded derivative possesses economic characteristics that are not clearly and closely related to the economic characteristics of the host contract and (2) a separate instrument with the same terms would qualify as a derivative instrument, the embedded derivative is bifurcated from the host for measurement purposes. The embedded derivative, which is reported with the host instrument on the Consolidated Balance Sheets, is carried at fair value with changes in fair value reported in net realized capital gains and losses. Credit Risk Credit risk is defined as the risk of financial loss due to uncertainty of an obligor’s or counterparty’s ability or willingness to meet its obligations in accordance with agreed upon terms. Credit exposures are measured using the market value of the derivatives, resulting in amounts owed to the Company by its counterparties or potential payment obligations from the Company to its counterparties. The Company generally requires that OTC derivative contracts, other than certain forward contracts, be governed by International Swaps and Derivatives Association ("ISDA") agreements which are structured by legal entity and by counterparty, and permit right of offset. Some agreements require daily collateral settlement based upon agreed upon thresholds. For purposes of daily derivative collateral maintenance, credit exposures are generally quantified based on the prior business day’s market value and collateral is pledged to and held by, or on behalf of, the Company to the extent the current value of the derivatives exceed the contractual thresholds. For the Company’s domestic derivative programs, the maximum uncollateralized threshold for a derivative counterparty for a single legal entity is $10. The Company also minimizes the credit risk of derivative instruments by entering into transactions with high quality counterparties primarily rated A or better, which are monitored and evaluated by the Company’s risk management team and reviewed by senior management. OTC-cleared derivatives are governed by clearing house rules. Transactions cleared through a central clearing house reduce risk due to their ability to require daily variation margin and act as an independent valuation source. In addition, the Company monitors counterparty credit exposure on a monthly basis to ensure compliance with Company policies and statutory limitations. Derivative Instruments The Company utilizes a variety of OTC, OTC-cleared and exchange traded derivative instruments as a part of its overall risk management strategy as well as to enter into replication transactions. Derivative instruments are used to manage risk associated with interest rate, equity market, credit spread, issuer default, price, and currency exchange rate risk or volatility. Replication transactions are used as an economical means to synthetically replicate the characteristics and performance of assets that are permissible investments under the Company’s investment policies. The Company also may enter into and has previously issued financial instruments and products that either are accounted for as free-standing derivatives, such as certain reinsurance contracts, or as embedded derivative instruments, such as certain GMWB riders included with certain variable annuity products.
Cash	Cash Cash represents cash on hand and demand deposits with banks or other financial institutions.
Reinsurance	Reinsurance The Company cedes insurance to unaffiliated insurers to enable the Company to manage capital and risk exposure. Such arrangements do not relieve the Company of its primary liability to policyholders. Failure of reinsurers to honor their obligations could result in losses to the Company. The Company also assumes reinsurance from other insurers. Reinsurance accounting is followed for ceded and assumed transactions that provide indemnification against loss or liability relating to insurance risk (i.e., risk transfer). To meet risk transfer requirements, a reinsurance agreement must include insurance risk, consisting of underwriting, investment, and timing risk, and a reasonable possibility of a significant loss to the reinsurer. If the ceded and assumed transactions do not meet risk transfer requirements, the Company accounts for these transactions as financing transactions. Premiums, benefits, losses and loss adjustment expenses reflect the net effects of ceded and assumed reinsurance transactions. Included in other assets are prepaid reinsurance premiums, which represent the portion of premiums ceded to reinsurers applicable to the unexpired terms of the reinsurance agreements. Included in reinsurance recoverables are balances due from reinsurance companies for paid and unpaid losses and loss adjustment expenses and are presented net of an ACL which is based on the expectation of lifetime credit loss. The Company reinsures certain of its risks to other reinsurers under yearly renewable term, coinsurance, and modified coinsurance arrangements, and variations thereof. The cost of reinsurance related to long-duration contracts is accounted for over the life of the underlying reinsured policies using assumptions consistent with those used to account for the underlying policies.
Deferred Policy Acquisition Costs and Present Value of Future Profits	Deferred Policy Acquisition Costs (Predecessor Company)/Value of Business Acquired (Successor Company) Deferred policy acquisition costs ("DAC") represent costs that are directly related to the acquisition of new and renewal insurance contracts and incremental direct costs of contract acquisition that are incurred in transactions with either independent third parties or employees. Such costs primarily include commissions, premium taxes, costs of policy issuance and underwriting, and certain other expenses that are directly related to successfully issued contracts. As a result of the Talcott Resolution Sale Transaction being recorded at fair value, DAC which does not represent future cash flows, was eliminated in pushdown accounting. VOBA represents the estimated value assigned to the right to receive future gross profits from cash flows and earnings of acquired insurance and investment contracts as of the date of the transaction. It is based on the actuarially estimated present value of future cash flows from the acquired insurance and investment contracts in-force as of the date of the transaction. The principal assumptions used in estimating the fair value calculation of VOBA include mortality, persistency, expenses, and interest rates, in addition to other factors that the Company expects to experience in future years. Actual experience on the acquired contracts may vary from these projections and the recovery of VOBA is dependent upon the future profitability of the related business. The Company amortizes VOBA over estimated gross profits ("EGPs") and it is reviewed for recoverability quarterly. Prior to June 2018, for universal life-type contracts (including variable annuities), the DAC asset was amortized over the estimated life of the contracts acquired in proportion to the present value of EGPs. The Company also uses the present value EGPs to determine reserves for universal life type contracts (including variable annuities) with death or other insurance benefits such as guaranteed minimum death, life-contingent guaranteed minimum withdrawal and universal life insurance secondary guarantee benefits. These benefits are accounted for and collectively referred to as death and other insurance benefit reserves and are held in addition to the account value liability representing policyholder funds. For most life insurance product contracts, including variable annuities, the Company estimates gross profits over 20 years as EGPs emerging subsequent to that time frame are immaterial. Future gross profits are projected over the estimated lives of the underlying contracts, based on future account value projections for variable annuity products. The projection of future account values requires the use of certain assumptions including: separate account returns; separate account fund mix; fees assessed against the contract holder’s account balance; f ull and partial surrender rates; interest credited; mortality; and annuitization rates. Changes in these assumptions and changes to other assumptions such as expenses and hedging costs cause EGPs to fluctuate, which impacts earnings. The Company determines EGPs using a set of stochastic reversion to mean ("RTM") separate account return projections which is an estimation technique commonly used by insurance entities to project future separate account returns. Through this estimation technique, the Company’s VOBA model is adjusted to reflect actual market returns at the end of each quarter. Through a consideration of recent market returns, the Company will unlock ("Unlock"), or adjust, projected returns over a future period so that the account value returns to the long-term expected rate of return, providing that those projected returns do not exceed certain caps. This Unlock for future separate account returns is determined each quarter.
Reserves for Future Policy Benefits and Unpaid Losses and Loss Adjustment	Reserve for Future Policy Benefits Reserve for Future Policy Benefits on Universal Life-type Contracts Certain contracts classified as universal life-type include death and other insurance benefit features including guaranteed minimum death benefit ("GMDB") and the life-contingent portion of guaranteed minimum withdrawal benefit ("GMWB") riders offered with variable annuity contracts, as well as secondary guarantee benefits offered with universal life insurance contracts. Universal life insurance secondary guarantee benefits ensure that the policy will not terminate, and will continue to provide a death benefit, even if there is insufficient policy value to cover the monthly deductions and charges. GMDB riders on variable annuities provide a death benefit during the accumulation phase that is generally equal to the greater of (a) the contract value at death or (b) premium payments less any prior withdrawals and may include adjustments that increase the benefit, such as for maximum anniversary value ("MAV"). For the Company's products with life-contingent GMWB riders, the withdrawal benefit can exceed the guaranteed remaining balance ("GRB"), which is generally equal to premiums less withdrawals. In addition to recording an account value liability that represents policyholder funds, the Company records a death and other insurance benefit liability for GMDBs, the life-contingent portion of GMWBs and the universal life insurance secondary guarantees. This death and other insurance benefit liability is reported in reserve for future policy benefits on the Company’s Consolidated Balance Sheets. Changes in the death and other insurance benefit reserves are recorded in benefits, losses and loss adjustment expenses on the Company’s Consolidated Statements of Operations. The death and other insurance benefit liability is determined by estimating the expected present value of the benefits in excess of the policyholder’s expected account value in proportion to the present value of total expected assessments and investment margin. Total expected assessments are the aggregate of all contract charges, including those for administration, mortality, expense, and surrender. The liability is accrued as actual assessments are earned. The expected present value of benefits and assessments are generally derived from a set of stochastic scenarios that have been calibrated to our RTM separate account returns and assumptions including market rates of return, volatility, discount rates, lapse rates and mortality experience. Consistent with the Company’s policy on the Unlock, the Company regularly evaluates estimates used and adjusts the liability, with a related charge or credit to benefits, losses and loss adjustment expenses. For further information on the Unlock, see the Deferred Policy Acquisition Costs (Predecessor Company)/Value of Business Acquired (Successor Company) accounting policy section within this footnote. The Company reinsures a portion of its in-force GMDB, GMWB, and all of its universal life insurance secondary guarantees. Net reinsurance costs are recognized ratably over the accumulation period based on total expected assessments. Reserve for Future Policy Benefits on Traditional Annuity and Other Contracts Traditional annuities recorded within the reserve for future policy benefits primarily include life-contingent contracts in the payout phase such as structured settlements and terminal funding agreements. Other contracts within the reserve for policyholder benefits include whole life and guaranteed term life insurance contracts. The reserve for future policy benefits is calculated using standard actuarial methods considering the present value of future benefits and related expenses to be paid less the present value of the portion of future premiums required using assumptions “locked in” at the time the policies were issued, including discount rate, withdrawal, mortality and expense assumptions deemed appropriate at the issue date. Future policy benefits are computed at amounts that, with additions from any estimated premiums to be received and with interest on such reserves compounded annually at assumed rates, are expected to be sufficient to meet the Company’s policy obligations at their maturities or in the event of an insured’s death. While assumptions are locked in upon issuance of new contracts and annuitizations of existing contracts, significant changes in experience or assumptions may require the Company to establish premium deficiency reserves. Premium deficiency reserves, if any, are established based on current assumptions without considering a provision for adverse deviation. Changes in or deviations from the assumptions used can significantly affect the Company’s reserve levels and results from operations. The Company uses reinsurance for a portion of its fixed and payout annuity businesses and its life insurance business.
Other Policyholder Funds and Benefits Payable	Other Policyholder Funds and Benefits Payable Other policyholder funds and benefits payable primarily include the non-variable account values associated with variable annuity and other universal life-type contracts, investment contracts, the non-life contingent portion of GMWBs that are accounted for as embedded derivatives at fair value as well as other policyholder account balances associated with our life insurance businesses. Investment contracts are non-life contingent and include institutional and governmental deposits, structured settlements and fixed annuities. The liability for investment contracts is equal to the balance that accrues to the benefit of the contract holder as of the financial statement date, which includes the accumulation of deposits plus credited interest, less withdrawals, payments and assessments through the financial statement date. For discussion of fair value of GMWBs that represent embedded derivatives, see Note 2 - Fair Value Measurements of Notes to Consolidated Financial Statements. Separate Account Liabilities The Company records the variable account value portion of variable annuities, variable life insurance products and individual, institutional, and governmental investment contracts within separate accounts. Separate account assets are reported at fair value and separate account liabilities are reported at amounts consistent with separate account assets. Investment income and gains and losses from those separate account assets accrue directly to the policyholder, who assumes the related investment risk, and are offset by change in the related liability. Changes in the value of separate account assets and separate account liabilities are reported in the same line item on the Consolidated Statements of Operations. The Company earns fee income for investment management, certain administrative services and mortality and expense risks.
Fair Value of Financial Instruments, Policy [Policy Text Block]	Valuation Techniques The Company generally determines fair values using valuation techniques that use prices, rates, and other relevant information evident from market transactions involving identical or similar instruments. Valuation techniques also include, where appropriate, estimates of future cash flows that are converted into a single discounted amount using current market expectations. The Company uses a "waterfall" approach comprised of the following pricing sources and techniques, which are listed in priority order: • Quoted prices, unadjusted, for identical assets or liabilities in active markets, which are classified as Level 1. • Prices from third-party pricing services, which primarily utilize a combination of techniques. These services utilize recently reported trades of identical, similar, or benchmark securities making adjustments for market observable inputs available through the reporting date. If there are no recently reported trades, they may use a discounted cash flow technique to develop a price using expected cash flows based upon the anticipated future performance of the underlying collateral discounted at an estimated market rate. Both techniques develop prices that consider the time value of future cash flows and provide a margin for risk, including liquidity and credit risk. Most prices provided by third-party pricing services are classified as Level 2 because the inputs used in pricing the securities are observable. However, some securities that are less liquid or trade less actively are classified as Level 3. Additionally, certain long-dated securities, such as municipal securities and bank loans, include benchmark interest rate or credit spread assumptions that are not observable in the marketplace and are thus classified as Level 3. • Internal matrix pricing, which is a valuation process internally developed for private placement securities for which the Company is unable to obtain a price from a third-party pricing service. Internal pricing matrices determine credit spreads that, when combined with risk-free rates, are applied to contractual cash flows to develop a price. The Company develops credit spreads using market based data for public securities adjusted for credit spread differentials between public and private securities, which are obtained from a survey of multiple private placement brokers. The market-based reference credit spread considers the issuer’s financial strength and term to maturity, using an independent public security index, while the credit spread differential considers the non-public nature of the security. Securities priced using internal matrix pricing are classified as Level 2 because the inputs are observable or can be corroborated with observable data. • Independent broker quotes, which are typically non-binding use inputs that can be difficult to corroborate with observable market based data. Brokers may use present value techniques using assumptions specific to the security types, or they may use recent transactions of similar securities. Due to the lack of transparency in the process that brokers use to develop prices, valuations that are based on independent broker quotes are classified as Level 3. The fair value of free-standing derivative instruments is determined primarily using a discounted cash flow model or option model technique and incorporates counterparty credit risk. In some cases, quoted market prices for exchange-traded and OTC cleared derivatives may be used and in other cases independent broker quotes may be used. The pricing valuation models primarily use inputs that are observable in the market or can be corroborated by observable market data. The valuation of certain derivatives may include significant inputs that are unobservable, such as volatility levels, and reflect the Company’s view of what other market participants would use when pricing such instruments. Unobservable market data is used in the valuation of customized derivatives that are used to hedge certain GMWB variable annuity riders. See the section “GMWB Embedded, Customized, and Reinsurance Derivatives” below for further discussion of the valuation model used to value these customized derivatives. Valuation Inputs Quoted prices for identical assets in active markets are considered Level 1 and consist of on-the-run U.S. Treasuries, money market funds, exchange-traded equity securities, open-ended mutual funds, certain short-term investments, and exchange traded futures and option contracts. Valuation Inputs Used in Levels 2 and 3 Measurements for Securities and Freestanding Derivatives Level 2 Level 3 Fixed Maturity Investments Structured securities (includes ABS, CLOs, CMBS and RMBS) • Benchmark yields and spreads Other inputs for ABS, CLOs, and RMBS: • Independent broker quotes Other inputs for less liquid securities or those that trade less actively, including subprime RMBS: Corporates • Benchmark yields and spreads Other inputs for investment grade privately placed securities that utilize internal matrix pricing: • Independent broker quotes Other inputs for below investment grade privately placed securities: U.S Treasuries, Municipals, and Foreign government/government agencies • Benchmark yields and spreads • Credit spreads beyond observable curve Equity Securities • Quoted prices in markets that are not active • For privately traded equity securities, internal discounted cash flow models utilizing earnings multiples or other cash flow assumptions that are not observable Short-term Investments • Benchmark yields and spreads • Independent broker quotes Derivatives Credit derivatives • Swap yield curve Not applicable Equity derivatives • Equity index levels • Independent broker quotes Foreign exchange derivatives • Swap yield curve Not applicable Interest rate derivatives • Swap yield curve • Independent broker quotes GMWB Embedded, Customized and Reinsurance Derivatives GMWB Embedded Derivatives The Company formerly offered certain variable annuity products with GMWB riders that provide the policyholder with a guaranteed remaining balance ("GRB") which is generally equal to premiums less withdrawals. If the policyholder’s account value is reduced to a specified level through a combination of market declines and withdrawals but the GRB still has value, the Company is obligated to continue to make annuity payments to the policyholder until the GRB is exhausted. When payments of the GRB are not life-contingent, the GMWB represents an embedded derivative carried at fair value reported in other policyholder funds and benefits payable on the Consolidated Balance Sheets with changes in fair value reported in net realized capital gains and losses. Free-standing Customized Derivatives The Company holds free-standing customized derivative contracts to provide protection from certain capital markets risks for the remaining term of specified blocks of non-reinsured GMWB riders. These customized derivatives are based on policyholder behavior assumptions specified at the inception of the derivative contracts. The Company retains the risk for differences between assumed and actual policyholder behavior and between the performance of the actively managed funds underlying the separate accounts and their respective indices. These derivatives are reported on the Consolidated Balance Sheets within other investments or other liabilities, as appropriate, after considering the impact of master netting agreements. GMWB Reinsurance Derivative The Company has reinsurance arrangements in place to transfer a portion of its risk of loss due to GMWB. These arrangements are recognized as derivatives carried at fair value and reported in reinsurance recoverables on the Consolidated Balance Sheets. Changes in the fair value of the reinsurance agreements are reported in net realized capital gains and losses. Valuation Techniques Fair values for GMWB embedded derivatives, free-standing customized derivatives and reinsurance derivatives are classified as Level 3 in the fair value hierarchy and are calculated using internally developed models that utilize significant unobservable inputs because active, observable markets do not exist for these items. In valuing the GMWB embedded derivative, the Company attributes to the derivative a portion of the expected fees to be collected over the expected life of the contract from the contract holder equal to the present value of future GMWB claims. The excess of fees collected from the contract holder in the current period over the portion of fees attributed to the embedded derivative in the current period are associated with the host variable annuity contract and reported in fee income. Valuation Inputs The fair value for each of the non-life contingent GMWBs, the free-standing customized derivatives and the GMWB reinsurance derivative is calculated as an aggregation of the following components: Best Estimate Claim Payments; Credit Standing Adjustment; and Margins. The Company believes the aggregation of these components results in an amount that a market participant in an active liquid market would require, if such a market existed, to assume the risks associated with the guaranteed minimum benefits and the related reinsurance and customized derivatives. Each component described in the following discussion is unobservable in the marketplace and requires subjectivity by the Company in determining its value. Best Estimate Claim Payments The Best Estimate Claim Payments are calculated based on actuarial and capital market assumptions related to projected cash flows, including the present value of benefits and related contract charges, over the lives of the contracts, incorporating unobservable inputs including expectations concerning policyholder behavior. Credit Standing Adjustment The credit standing adjustment is an estimate of the adjustment to the fair value that market participants would require in determining fair value to reflect the risk that GMWB benefit obligations or the GMWB reinsurance recoverables will not be fulfilled. The Company incorporates a blend of estimates of peer company and reinsurer bond spreads and credit default spreads from capital markets, adjusted for market recoverability. Margins The behavior risk margin adds a margin that market participants would require, in determining fair value, for the risk that the Company’s assumptions about policyholder behavior could differ from actual experience. The behavior risk margin is calculated by taking the difference between adverse policyholder behavior assumptions and best estimate assumptions. Valuation Inputs Used in Levels 2 and 3 Measurements for GMWB Embedded, Customized and Reinsurance Derivatives Level 2 Level 3 • Risk-free rates as represented by the Eurodollar futures, LIBOR deposits and swap rates to derive forward curve rates • Market implied equity volatility assumptions Assumptions about policyholder behavior, including:
Derivatives, Methods of Accounting, Hedge Documentation [Policy Text Block]	Strategies that Qualify for Hedge Accounting Some of the Company's derivatives satisfy hedge accounting requirements as outlined in Note 1 of these financial statements. Typically, these hedging instruments include interest rate swaps and, to a lesser extent, foreign currency swaps where the terms or expected cash flows of the hedged item closely match the terms of the swap. The interest rate swaps are typically used to manage interest rate duration of certain fixed maturity securities or liability contracts. As a result of pushdown accounting, derivative instruments that previously qualified for hedge accounting were de-designated and recorded at fair value through adjustments to additional paid in capital at the acquisition date. The hedge strategies by hedge accounting designation include: Cash Flow Hedges Interest rate swaps are predominantly used to manage portfolio duration and better match cash receipts from assets with cash disbursements required to fund liabilities. These derivatives primarily convert interest receipts on floating-rate fixed maturity securities to fixed rates. Foreign currency swaps are used to convert foreign currency-denominated cash flows related to certain investment receipts and liability payments to U.S. dollars in order to reduce cash flow fluctuations due to changes in currency rates. Non-qualifying Strategies Derivative relationships that do not qualify for hedge accounting (“non-qualifying strategies”) primarily include the hedge program for the Company's variable annuity products as well as the hedging and replication strategies that utilize credit default swaps. In addition, hedges of interest rate, foreign currency and equity risk of certain fixed maturities, equities and liabilities do not qualify for hedge accounting. The non-qualifying strategies include: Interest Rate Swaps, Swaptions and Futures The Company uses interest rate swaps, swaptions and futures to manage interest rate duration between assets and liabilities in certain investment portfolios. In addition, the Company enters into interest rate swaps to terminate existing swaps, thereby offsetting the changes in value of the original swap. As of December 31, 2020 and 2019 (Successor Company), the notional amount of interest rate swaps in offsetting relationships was $1.3 billion for both years. Foreign Currency Swaps and Forwards The Company enters into foreign currency swaps to convert the foreign currency exposures of certain foreign currency-denominated fixed maturity investments to U.S. dollars. The Company also enters into foreign currency forwards to hedge non-U.S. dollar denominated cash. Fixed Payout Annuity Hedge The Company previously had obligations for certain yen denominated fixed payout annuities under an assumed reinsurance contract. The Company had in place swap contracts to hedge the currency and yen interest rate exposure between the U.S. dollar denominated assets and the yen denominated fixed liability reinsurance payments. The last swap matured on October 31, 2019. Credit Contracts Credit default swaps are used to purchase credit protection on an individual entity or referenced index to economically hedge against default risk and credit-related changes in the value of fixed maturity securities. Credit default swaps are also used to assume credit risk related to an individual entity or referenced index as a part of replication transactions. These contracts require the Company to pay or receive a periodic fee in exchange for compensation from the counterparty or the Company should the referenced security issuers experience a credit event, as defined in the contract. In addition, the Company enters into credit default swaps to terminate existing credit default swaps, thereby offsetting the changes in value of the original swap going forward. Equity Index Swaps and Options The Company enters into equity index options to hedge the impact of a decline in the equity markets on the investment portfolio. Macro Hedge Program The Company utilizes equity swaps, options and futures as well as interest rate swaps to provide protection against the statutory tail scenario risk to the Company's statutory surplus arising from higher GMWB and guaranteed minimum death benefits ("GMDB") claims as well as lower variable annuity fee revenue. GMWB Derivatives, net The Company formerly offered certain variable annuity products with GMWB riders. The GMWB product is a bifurcated embedded derivative (“GMWB product derivatives”) that has a notional value equal to the GRB. The Company uses reinsurance contracts to transfer a portion of its risk of loss due to GMWB. The reinsurance contracts covering GMWB (“GMWB reinsurance contracts”) are accounted for as free-standing derivatives with a notional amount equal to the GRB reinsured. During 2020, the Company closed the dynamic hedging program as the targeted risk exposure was no longer significant. Any risks covered previously under the dynamic hedging program are now covered by the macro hedge program. The Company previously utilized derivatives (“GMWB hedging instruments”) as part of a dynamic hedging program designed to hedge a portion of the capital market risk exposures of the non-reinsured GMWB riders. The GMWB hedging instruments hedged changes in interest rates, equity market levels, and equity volatility. These derivatives included customized swaps, interest rate swaps and futures, and equity swaps, options and futures, on certain indices including the S&P 500 index, EAFE index and NASDAQ index. The Company retained the risk for differences between assumed and actual policyholder behavior and between the performance of the actively managed funds underlying the separate accounts and their respective indices.
Commitments and Contingencies, Policy [Policy Text Block]	Contingencies Relating to Corporate Litigation and Regulatory Matters Management evaluates each contingent matter separately. A loss is recorded if probable and reasonably estimable. Management establishes reserves for these contingencies at its “best estimate,” or, if no one number within the range of possible losses is more probable than any other, the Company records an estimated liability at the low end of the range of losses.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments, Policy [Policy Text Block]	Valuation Techniques The Company generally determines fair values using valuation techniques that use prices, rates, and other relevant information evident from market transactions involving identical or similar instruments. Valuation techniques also include, where appropriate, estimates of future cash flows that are converted into a single discounted amount using current market expectations. The Company uses a "waterfall" approach comprised of the following pricing sources and techniques, which are listed in priority order: • Quoted prices, unadjusted, for identical assets or liabilities in active markets, which are classified as Level 1. • Prices from third-party pricing services, which primarily utilize a combination of techniques. These services utilize recently reported trades of identical, similar, or benchmark securities making adjustments for market observable inputs available through the reporting date. If there are no recently reported trades, they may use a discounted cash flow technique to develop a price using expected cash flows based upon the anticipated future performance of the underlying collateral discounted at an estimated market rate. Both techniques develop prices that consider the time value of future cash flows and provide a margin for risk, including liquidity and credit risk. Most prices provided by third-party pricing services are classified as Level 2 because the inputs used in pricing the securities are observable. However, some securities that are less liquid or trade less actively are classified as Level 3. Additionally, certain long-dated securities, such as municipal securities and bank loans, include benchmark interest rate or credit spread assumptions that are not observable in the marketplace and are thus classified as Level 3. • Internal matrix pricing, which is a valuation process internally developed for private placement securities for which the Company is unable to obtain a price from a third-party pricing service. Internal pricing matrices determine credit spreads that, when combined with risk-free rates, are applied to contractual cash flows to develop a price. The Company develops credit spreads using market based data for public securities adjusted for credit spread differentials between public and private securities, which are obtained from a survey of multiple private placement brokers. The market-based reference credit spread considers the issuer’s financial strength and term to maturity, using an independent public security index, while the credit spread differential considers the non-public nature of the security. Securities priced using internal matrix pricing are classified as Level 2 because the inputs are observable or can be corroborated with observable data. • Independent broker quotes, which are typically non-binding use inputs that can be difficult to corroborate with observable market based data. Brokers may use present value techniques using assumptions specific to the security types, or they may use recent transactions of similar securities. Due to the lack of transparency in the process that brokers use to develop prices, valuations that are based on independent broker quotes are classified as Level 3. The fair value of free-standing derivative instruments is determined primarily using a discounted cash flow model or option model technique and incorporates counterparty credit risk. In some cases, quoted market prices for exchange-traded and OTC cleared derivatives may be used and in other cases independent broker quotes may be used. The pricing valuation models primarily use inputs that are observable in the market or can be corroborated by observable market data. The valuation of certain derivatives may include significant inputs that are unobservable, such as volatility levels, and reflect the Company’s view of what other market participants would use when pricing such instruments. Unobservable market data is used in the valuation of customized derivatives that are used to hedge certain GMWB variable annuity riders. See the section “GMWB Embedded, Customized, and Reinsurance Derivatives” below for further discussion of the valuation model used to value these customized derivatives. Valuation Inputs Quoted prices for identical assets in active markets are considered Level 1 and consist of on-the-run U.S. Treasuries, money market funds, exchange-traded equity securities, open-ended mutual funds, certain short-term investments, and exchange traded futures and option contracts. Valuation Inputs Used in Levels 2 and 3 Measurements for Securities and Freestanding Derivatives Level 2 Level 3 Fixed Maturity Investments Structured securities (includes ABS, CLOs, CMBS and RMBS) • Benchmark yields and spreads Other inputs for ABS, CLOs, and RMBS: • Independent broker quotes Other inputs for less liquid securities or those that trade less actively, including subprime RMBS: Corporates • Benchmark yields and spreads Other inputs for investment grade privately placed securities that utilize internal matrix pricing: • Independent broker quotes Other inputs for below investment grade privately placed securities: U.S Treasuries, Municipals, and Foreign government/government agencies • Benchmark yields and spreads • Credit spreads beyond observable curve Equity Securities • Quoted prices in markets that are not active • For privately traded equity securities, internal discounted cash flow models utilizing earnings multiples or other cash flow assumptions that are not observable Short-term Investments • Benchmark yields and spreads • Independent broker quotes Derivatives Credit derivatives • Swap yield curve Not applicable Equity derivatives • Equity index levels • Independent broker quotes Foreign exchange derivatives • Swap yield curve Not applicable Interest rate derivatives • Swap yield curve • Independent broker quotes GMWB Embedded, Customized and Reinsurance Derivatives GMWB Embedded Derivatives The Company formerly offered certain variable annuity products with GMWB riders that provide the policyholder with a guaranteed remaining balance ("GRB") which is generally equal to premiums less withdrawals. If the policyholder’s account value is reduced to a specified level through a combination of market declines and withdrawals but the GRB still has value, the Company is obligated to continue to make annuity payments to the policyholder until the GRB is exhausted. When payments of the GRB are not life-contingent, the GMWB represents an embedded derivative carried at fair value reported in other policyholder funds and benefits payable on the Consolidated Balance Sheets with changes in fair value reported in net realized capital gains and losses. Free-standing Customized Derivatives The Company holds free-standing customized derivative contracts to provide protection from certain capital markets risks for the remaining term of specified blocks of non-reinsured GMWB riders. These customized derivatives are based on policyholder behavior assumptions specified at the inception of the derivative contracts. The Company retains the risk for differences between assumed and actual policyholder behavior and between the performance of the actively managed funds underlying the separate accounts and their respective indices. These derivatives are reported on the Consolidated Balance Sheets within other investments or other liabilities, as appropriate, after considering the impact of master netting agreements. GMWB Reinsurance Derivative The Company has reinsurance arrangements in place to transfer a portion of its risk of loss due to GMWB. These arrangements are recognized as derivatives carried at fair value and reported in reinsurance recoverables on the Consolidated Balance Sheets. Changes in the fair value of the reinsurance agreements are reported in net realized capital gains and losses. Valuation Techniques Fair values for GMWB embedded derivatives, free-standing customized derivatives and reinsurance derivatives are classified as Level 3 in the fair value hierarchy and are calculated using internally developed models that utilize significant unobservable inputs because active, observable markets do not exist for these items. In valuing the GMWB embedded derivative, the Company attributes to the derivative a portion of the expected fees to be collected over the expected life of the contract from the contract holder equal to the present value of future GMWB claims. The excess of fees collected from the contract holder in the current period over the portion of fees attributed to the embedded derivative in the current period are associated with the host variable annuity contract and reported in fee income. Valuation Inputs The fair value for each of the non-life contingent GMWBs, the free-standing customized derivatives and the GMWB reinsurance derivative is calculated as an aggregation of the following components: Best Estimate Claim Payments; Credit Standing Adjustment; and Margins. The Company believes the aggregation of these components results in an amount that a market participant in an active liquid market would require, if such a market existed, to assume the risks associated with the guaranteed minimum benefits and the related reinsurance and customized derivatives. Each component described in the following discussion is unobservable in the marketplace and requires subjectivity by the Company in determining its value. Best Estimate Claim Payments The Best Estimate Claim Payments are calculated based on actuarial and capital market assumptions related to projected cash flows, including the present value of benefits and related contract charges, over the lives of the contracts, incorporating unobservable inputs including expectations concerning policyholder behavior. Credit Standing Adjustment The credit standing adjustment is an estimate of the adjustment to the fair value that market participants would require in determining fair value to reflect the risk that GMWB benefit obligations or the GMWB reinsurance recoverables will not be fulfilled. The Company incorporates a blend of estimates of peer company and reinsurer bond spreads and credit default spreads from capital markets, adjusted for market recoverability. Margins The behavior risk margin adds a margin that market participants would require, in determining fair value, for the risk that the Company’s assumptions about policyholder behavior could differ from actual experience. The behavior risk margin is calculated by taking the difference between adverse policyholder behavior assumptions and best estimate assumptions. Valuation Inputs Used in Levels 2 and 3 Measurements for GMWB Embedded, Customized and Reinsurance Derivatives Level 2 Level 3 • Risk-free rates as represented by the Eurodollar futures, LIBOR deposits and swap rates to derive forward curve rates • Market implied equity volatility assumptions Assumptions about policyholder behavior, including:

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Derivative Instruments Overview The Company utilizes a variety of over-the-counter ("OTC") transactions cleared through central clearing houses ("OTC-cleared") and exchange traded derivative instruments as part of its overall risk management strategy as well as to enter into replication transactions. The types of instruments may include swaps, caps, floors, forwards, futures and options to achieve one of four Company-approved objectives: • to hedge risk arising from interest rate, equity market, commodity market, credit spread and issuer default, price or currency exchange rate risk or volatility; • to manage liquidity; • to control transaction costs; • to enter into synthetic replication transactions. Interest rate and credit default swaps involve the periodic exchange of cash flows with other parties, at specified intervals, calculated using agreed upon rates or other financial variables and notional principal amounts. Generally, little to no cash or principal payments are exchanged at the inception of the contract. Typically, at the time a swap is entered into, the cash flow streams exchanged by the counterparties are equal in value. Interest rate cap and floor contracts entitle the purchaser to receive from the issuer at specified dates, the amount, if any, by which a specified market rate exceeds the cap strike interest rate or falls below the floor strike interest rate, applied to a notional principal amount. A premium payment determined at inception is made by the purchaser of the contract and no principal payments are exchanged. Forward contracts are customized commitments that specify a rate of interest or currency exchange rate to be paid or received on an obligation beginning on a future start date and are typically settled in cash. Financial futures are standardized commitments to either purchase or sell designated financial instruments, at a future date, for a specified price and may be settled in cash or through delivery of the underlying instrument. Futures contracts trade on organized exchanges. Margin requirements for futures are met by pledging securities or cash, and changes in the futures’ contract values are settled daily in cash. Option contracts grant the purchaser, for a premium payment, the right to either purchase from or sell to the issuer a financial instrument at a specified price, within a specified period or on a stated date. The contracts may reference commodities, which grant the purchaser the right to either purchase from or sell to the issuer commodities at a specified price, within a specified period or on a stated date. Option contracts are typically settled in cash. Foreign currency swaps exchange an initial principal amount in two currencies, agreeing to re-exchange the currencies at a future date, at an agreed upon exchange rate. There may also be a periodic exchange of payments at specified intervals calculated using the agreed upon rates and exchanged principal amounts. The Company’s derivative transactions conducted in insurance company subsidiaries are used in strategies permitted under the derivative use plans required by the State of Connecticut and the State of New York insurance departments. Accounting and Financial Statement Presentation of Derivative Instruments and Hedging Activities Derivative instruments are recognized on the Consolidated Balance Sheets at fair value and are reported in Other Investments and Other Liabilities. For balance sheet presentation purposes, the Company has elected to offset the fair value amounts, income accruals, and related cash collateral receivables and payables of OTC derivative instruments executed in a legal entity and with the same counterparty or under a master netting agreement, which provides the Company with the legal right of offset. The Company clears certain interest rate swap and credit default swap derivative transactions through central clearing houses. OTC-cleared derivatives require initial collateral at the inception of the trade in the form of cash or highly liquid securities, such as U.S. Treasuries and government agency investments. Central clearing houses also require additional cash as variation margin based on daily market value movements. For information on collateral, see the derivative collateral arrangements section in Note 4 - Derivative Instruments of Notes to Consolidated Financial Statements. In addition, OTC-cleared transactions include price alignment amounts either received or paid on the variation margin, which are reflected in realized capital gains and losses or, if characterized as interest, in net investment income. On the date the derivative contract is entered into, the Company designates the derivative as (1) a hedge of the variability in cash flows of a forecasted transaction or of amounts to be received or paid related to a recognized asset or liability (“cash flow” hedge), (2) a hedge of a net investment in a foreign operation (“net investment” hedge) or (3) held for other investment and/or risk management purposes, which primarily involve managing asset or liability related risks and do not qualify for hedge accounting. Cash Flow Hedges - Changes in the fair value of a derivative that is designated and qualifies as a cash flow hedge, including foreign-currency cash flow hedges, are recorded in AOCI and are reclassified into earnings when the variability of the cash flow of the hedged item impacts earnings. Gains and losses on derivative contracts that are reclassified from AOCI to current period earnings are included in the line item in the Consolidated Statements of Operations in which the cash flows of the hedged item are recorded. For periods prior to 2019, hedge ineffectiveness was recorded immediately in current period earnings as net realized capital gains and losses. With the January 1, 2019 adoption of the updated FASB hedging guidance, ineffectiveness is recognized in earnings only when the hedged transaction affects earnings; otherwise, the ineffectiveness gains and losses remain in AOCI. Periodic derivative net coupon settlements are recorded in the line item of the Consolidated Statements of Operations in which the cash flows of the hedged item are recorded. Cash flows from cash flow hedges are presented in the same category as the cash flows from the items being hedged on the Consolidated Statements of Cash Flows. Other Investment and/or Risk Management Activities - The Company’s other investment and/or risk management activities primarily relate to strategies used to reduce economic risk or replicate permitted investments and do not receive hedge accounting treatment. Changes in the fair value, including periodic derivative net coupon settlements, of derivative instruments held for other investment and/or risk management purposes are reported in current period earnings as net realized capital gains and losses. Hedge Documentation and Effectiveness Testing To qualify for hedge accounting treatment, a derivative must be highly effective in mitigating the designated changes in fair value or cash flow of the hedged item. At hedge inception, the Company formally documents all relationships between hedging instruments and hedged items, as well as its risk-management objective and strategy for undertaking each hedge transaction. The documentation process includes linking derivatives that are designated as fair value, cash flow, or net investment hedges to specific assets or liabilities on the balance sheet or to specific forecasted transactions and defining the effectiveness testing methods to be used. The Company also formally assesses both at the hedge’s inception and ongoing on a quarterly basis, whether the derivatives that are used in hedging transactions have been and are expected to continue to be highly effective in offsetting changes in fair values, cash flows or net investment in foreign operations of hedged items. Hedge effectiveness is assessed primarily using quantitative methods as well as using qualitative methods. Quantitative methods include regression or other statistical analysis of changes in fair value or cash flows associated with the hedge relationship. Qualitative methods may include comparison of critical terms of the derivative to the hedged item. Discontinuance of Hedge Accounting The Company discontinues hedge accounting prospectively when (1) it is determined that the qualifying criteria are no longer met; (2) the derivative is no longer designated as a hedging instrument; or (3) the derivative expires or is sold, terminated or exercised. When cash flow hedge accounting is discontinued because the Company becomes aware that it is not probable that the forecasted transaction will occur, the derivative continues to be carried on the balance sheet at its fair value, and gains and losses that were accumulated in AOCI are recognized immediately in earnings. In other situations in which hedge accounting is discontinued, including those where the derivative is sold, terminated or exercised, amounts previously deferred in AOCI are reclassified into earnings when earnings are impacted by the hedged item. Embedded Derivatives The Company purchases investments and has previously issued financial products that contain embedded derivative instruments. When it is determined that (1) the embedded derivative possesses economic characteristics that are not clearly and closely related to the economic characteristics of the host contract and (2) a separate instrument with the same terms would qualify as a derivative instrument, the embedded derivative is bifurcated from the host for measurement purposes. The embedded derivative, which is reported with the host instrument on the Consolidated Balance Sheets, is carried at fair value with changes in fair value reported in net realized capital gains and losses. Credit Risk Credit risk is defined as the risk of financial loss due to uncertainty of an obligor’s or counterparty’s ability or willingness to meet its obligations in accordance with agreed upon terms. Credit exposures are measured using the market value of the derivatives, resulting in amounts owed to the Company by its counterparties or potential payment obligations from the Company to its counterparties. The Company generally requires that OTC derivative contracts, other than certain forward contracts, be governed by International Swaps and Derivatives Association ("ISDA") agreements which are structured by legal entity and by counterparty, and permit right of offset. Some agreements require daily collateral settlement based upon agreed upon thresholds. For purposes of daily derivative collateral maintenance, credit exposures are generally quantified based on the prior business day’s market value and collateral is pledged to and held by, or on behalf of, the Company to the extent the current value of the derivatives exceed the contractual thresholds. For the Company’s domestic derivative programs, the maximum uncollateralized threshold for a derivative counterparty for a single legal entity is $10. The Company also minimizes the credit risk of derivative instruments by entering into transactions with high quality counterparties primarily rated A or better, which are monitored and evaluated by the Company’s risk management team and reviewed by senior management. OTC-cleared derivatives are governed by clearing house rules. Transactions cleared through a central clearing house reduce risk due to their ability to require daily variation margin and act as an independent valuation source. In addition, the Company monitors counterparty credit exposure on a monthly basis to ensure compliance with Company policies and statutory limitations. Derivative Instruments The Company utilizes a variety of OTC, OTC-cleared and exchange traded derivative instruments as a part of its overall risk management strategy as well as to enter into replication transactions. Derivative instruments are used to manage risk associated with interest rate, equity market, credit spread, issuer default, price, and currency exchange rate risk or volatility. Replication transactions are used as an economical means to synthetically replicate the characteristics and performance of assets that are permissible investments under the Company’s investment policies. The Company also may enter into and has previously issued financial instruments and products that either are accounted for as free-standing derivatives, such as certain reinsurance contracts, or as embedded derivative instruments, such as certain GMWB riders included with certain variable annuity products.
Derivatives, Methods of Accounting, Hedge Documentation [Policy Text Block]	Strategies that Qualify for Hedge Accounting Some of the Company's derivatives satisfy hedge accounting requirements as outlined in Note 1 of these financial statements. Typically, these hedging instruments include interest rate swaps and, to a lesser extent, foreign currency swaps where the terms or expected cash flows of the hedged item closely match the terms of the swap. The interest rate swaps are typically used to manage interest rate duration of certain fixed maturity securities or liability contracts. As a result of pushdown accounting, derivative instruments that previously qualified for hedge accounting were de-designated and recorded at fair value through adjustments to additional paid in capital at the acquisition date. The hedge strategies by hedge accounting designation include: Cash Flow Hedges Interest rate swaps are predominantly used to manage portfolio duration and better match cash receipts from assets with cash disbursements required to fund liabilities. These derivatives primarily convert interest receipts on floating-rate fixed maturity securities to fixed rates. Foreign currency swaps are used to convert foreign currency-denominated cash flows related to certain investment receipts and liability payments to U.S. dollars in order to reduce cash flow fluctuations due to changes in currency rates. Non-qualifying Strategies Derivative relationships that do not qualify for hedge accounting (“non-qualifying strategies”) primarily include the hedge program for the Company's variable annuity products as well as the hedging and replication strategies that utilize credit default swaps. In addition, hedges of interest rate, foreign currency and equity risk of certain fixed maturities, equities and liabilities do not qualify for hedge accounting. The non-qualifying strategies include: Interest Rate Swaps, Swaptions and Futures The Company uses interest rate swaps, swaptions and futures to manage interest rate duration between assets and liabilities in certain investment portfolios. In addition, the Company enters into interest rate swaps to terminate existing swaps, thereby offsetting the changes in value of the original swap. As of December 31, 2020 and 2019 (Successor Company), the notional amount of interest rate swaps in offsetting relationships was $1.3 billion for both years. Foreign Currency Swaps and Forwards The Company enters into foreign currency swaps to convert the foreign currency exposures of certain foreign currency-denominated fixed maturity investments to U.S. dollars. The Company also enters into foreign currency forwards to hedge non-U.S. dollar denominated cash. Fixed Payout Annuity Hedge The Company previously had obligations for certain yen denominated fixed payout annuities under an assumed reinsurance contract. The Company had in place swap contracts to hedge the currency and yen interest rate exposure between the U.S. dollar denominated assets and the yen denominated fixed liability reinsurance payments. The last swap matured on October 31, 2019. Credit Contracts Credit default swaps are used to purchase credit protection on an individual entity or referenced index to economically hedge against default risk and credit-related changes in the value of fixed maturity securities. Credit default swaps are also used to assume credit risk related to an individual entity or referenced index as a part of replication transactions. These contracts require the Company to pay or receive a periodic fee in exchange for compensation from the counterparty or the Company should the referenced security issuers experience a credit event, as defined in the contract. In addition, the Company enters into credit default swaps to terminate existing credit default swaps, thereby offsetting the changes in value of the original swap going forward. Equity Index Swaps and Options The Company enters into equity index options to hedge the impact of a decline in the equity markets on the investment portfolio. Macro Hedge Program The Company utilizes equity swaps, options and futures as well as interest rate swaps to provide protection against the statutory tail scenario risk to the Company's statutory surplus arising from higher GMWB and guaranteed minimum death benefits ("GMDB") claims as well as lower variable annuity fee revenue. GMWB Derivatives, net The Company formerly offered certain variable annuity products with GMWB riders. The GMWB product is a bifurcated embedded derivative (“GMWB product derivatives”) that has a notional value equal to the GRB. The Company uses reinsurance contracts to transfer a portion of its risk of loss due to GMWB. The reinsurance contracts covering GMWB (“GMWB reinsurance contracts”) are accounted for as free-standing derivatives with a notional amount equal to the GRB reinsured. During 2020, the Company closed the dynamic hedging program as the targeted risk exposure was no longer significant. Any risks covered previously under the dynamic hedging program are now covered by the macro hedge program. The Company previously utilized derivatives (“GMWB hedging instruments”) as part of a dynamic hedging program designed to hedge a portion of the capital market risk exposures of the non-reinsured GMWB riders. The GMWB hedging instruments hedged changes in interest rates, equity market levels, and equity volatility. These derivatives included customized swaps, interest rate swaps and futures, and equity swaps, options and futures, on certain indices including the S&P 500 index, EAFE index and NASDAQ index. The Company retained the risk for differences between assumed and actual policyholder behavior and between the performance of the actively managed funds underlying the separate accounts and their respective indices.

Roll-forward of Financial Instruments Measured at Fair Value on a Recurring Basis Using Significant Unobservable Inputs (Level 3)	Level 3 Assets and Liabilities Measured at Fair Value on a Recurring Basis Using Significant Unobservable Inputs The Company uses derivative instruments to manage the risk associated with certain assets and liabilities. However, the derivative instrument may not be classified with the same fair value hierarchy level as the associated asset or liability. Therefore, the realized and unrealized gains and losses on derivatives reported in the Level 3 roll-forward may be offset by realized and unrealized gains and losses of the associated assets and liabilities in other line items of the financial statements.

Financing Receivable, Allowance for Credit Loss	Mortgage Loans ACL on Mortgage Loans The Company reviews mortgage loans on a quarterly basis to estimate the ACL, with changes in the ACL recorded in net realized capital gains and losses. Apart from an ACL recorded on individual mortgage loans where the borrower is experiencing financial difficulties, the Company records an ACL on the pool of mortgage loans based on lifetime expected credit losses. The Company utilizes a third-party forecasting model to estimate lifetime expected credit losses at a loan level under multiple economic scenarios. The scenarios use macroeconomic data provided by an internationally recognized economics firm that generates forecasts of varying economic factors such as GDP growth, unemployment and interest rates. The economic scenarios are projected over 10 years. The first two to four years of the 10-year period assume a specific modeled economic scenario (including moderate upside, moderate recession and severe recession scenarios) and then revert to historical long-term assumptions over the remaining period. Using these economic scenarios, the forecasting model projects property-specific operating income and capitalization rates used to estimate the value of a future operating income stream. The operating income and the property valuations derived from capitalization rates are compared to loan payment and principal amounts to create debt-service coverage ratios ("DSCRs") and LTVs over the forecast period. The model overlays historical data about mortgage loan performance based on DSCRs and LTVs and projects the probability of default, amount of loss given a default and resulting expected loss through maturity for each loan under each economic scenario. Economic scenarios are probability-weighted based on a statistical analysis of the forecasted economic factors and qualitative analysis. The Company records the change in the ACL on mortgage loans based on the weighted-average expected credit losses across the selected economic scenarios. In response to significant economic stress experienced as a result of the COVID-19 pandemic during 2020 the Company increased the weight of both a moderate and severe recession in our estimate of the ACL. The Company continues to monitor economic uncertainty including rising COVID-19 infections leading to short-term lockdowns and the corresponding impact that this might have on the mortgage loan portfolio. The ultimate impact to the Company’s financial statements could vary significantly from our estimates depending on, among other things, the duration and severity of the pandemic, the duration and severity of the economic downturn and the degree to which federal, state and local government actions to mitigate the economic impact of COVID-19 are effective. The impact on our commercial mortgage loan portfolio will also be impacted by borrower behavior in response to the economic stress. Borrowers with lower LTVs have an incentive to continue to make payments of principal and/or interest in order to preserve the equity they have in the underlying commercial real estate properties. As property values decline, borrowers have less incentive to continue to make payments. When a borrower is experiencing financial difficulty, including when foreclosure is probable, the Company measures an ACL on individual mortgage loans.The ACL is established for any shortfall between the amortized cost of the loan and the fair value of the collateral less costs to sell. Estimates of collectibility from an individual borrower require the use of significant management judgment and include the probability and timing of borrower default and loss severity estimates. In addition, cash flow projections may change based upon new information about the borrower's ability to pay and/or the value of underlying collateral such as changes in projected property value estimates. As of December 31, 2020 (Successor Company), the Company did not have any mortgage loans for which an ACL was established on an individual basis. There were no mortgage loans held-for-sale as of December 31, 2020 or 2019 (Successor Company). As of December 31, 2020 (Successor Company), the Company had no mortgage loans that have had extensions or restructurings other than what is allowable under the original terms of the contract. Prior to January 1, 2020, the accounting model was based on an incurred loss approach. Mortgage loans were considered to be impaired when management estimated that, based upon current information and events, it was probable that the Company would be unable to collect amounts due according to the contractual terms of the loan agreement. For mortgage loans that were deemed impaired, a valuation allowance was established for the difference between the carrying amount and estimated value. Changes in valuation allowances were recorded in net realized capital gains and losses.

Reinsurance [Text Block]			The Company cedes insurance to unaffiliated insurers to enable the Company to manage capital and risk exposure. Such arrangements do not relieve the Company of its primary liability to policyholders. Failure of reinsurers to honor their obligations could result in losses to the Company. The Company regularly monitors the financial condition and ratings of its reinsurers and structures agreements to provide collateral funds where necessary. Reinsurance Recoverables Reinsurance recoverables include balances due from reinsurance companies and are presented net of allowances for uncollectible reinsurance in 2019 and net of ACL in 2020, upon adoption of ASU 2016-13. For further information, see Note 1 - Basis of Presentation and Significant Accounting Policies of Notes to Consolidated Financial Statements. The ACL represents an estimate of expected credit losses over the lifetime of the contracts that reflect management’s best estimate of reinsurance cessions that may be uncollectible in the future due to reinsurers’ inability to pay. Reinsurance recoverables include an estimate of the amount of policyholder benefits that may be ceded under the terms of the reinsurance agreements. Amounts recoverable from reinsurers are estimated in a manner consistent with assumptions used for the underlying policy benefits. Accordingly, the Company’s estimate of reinsurance recoverables is subject to similar risks and uncertainties as the estimate of the gross reserve for future policy benefits. Reinsurance Recoverables, net (Successor Company) As of December 31, 2020 2019 Reserve for future policy benefits and other policyholder funds and benefits payable Sold businesses (MassMutual and Prudential) $ 18,807 $ 19,534 Commonwealth 7,579 8,147 Other reinsurers 1,076 1,143 Gross reinsurance recoverables 27,462 28,824 Less: ACL 7 Reinsurance recoverables, net [1] $ 27,455 $ 28,824 [1] As of December 31, 2019 (Successor Company), no allowance for uncollectible reinsurance was required. As of December 31, 2020 (Successor Company), the Company had reinsurance recoverables from Commonwealth, Massachusetts Mutual Life Insurance Company ("MassMutual") and Prudential Financial, Inc. ("Prudential") of approximately $7.6 billion, $7.0 billion and $11.8 billion, respectively. As of December 31, 2019 (Successor Company), the Company had reinsurance recoverables from Commonwealth, MassMutual and Prudential of $8.1 billion, $8.0 billion and $11.5 billion, respectively. The Company's obligations to its direct policyholders that have been reinsured to Commonwealth, MassMutual and Prudential are primarily secured by invested assets held in trust. As of December 31, 2020 (Successor Company), the ACL increased to $7 from $5 at January 1, 2020, upon adoption of ASU 2016-13. The Company closely monitors the financial condition, ratings and current market information of all its counterparty reinsurers and records an ACL considering the credit quality of the reinsurer, the invested assets in trust, and the period over which the recoverable balances are expected to be collected. Counterparty risk is assessed on a pooled basis in cases of shared risk characteristics, and separately for individual reinsurers when it is more relevant. The Company evaluates historical events, current conditions, and reasonable and supportable forecasts in developing its ACL estimate. Where its contracts permit, the Company secures future claim obligations with various forms of collateral, including irrevocable letters of credit, secured trusts and funds held accounts. The ACL is estimated using a probability of default and loss given default model applied to the amount of reinsurance recoverables, net of collateral, exposed to loss. The probability of default factor is assigned based on each reinsurer's credit rating. The Company reassesses and updates credit ratings on a quarterly basis. The probability of default factors encompass historical industry defaults for liabilities with similar durations to the reinsured liabilities as estimated through multiple economic cycles. The loss given default factors are based on a study of historical recovery rates for general creditors of corporations through multiple economic cycles.

Insurance recoveries on ceded reinsurance agreements, which reduce death and other benefits, were $1.5 billion and $1.4 billion for the years ended December 31, 2020 and 2019 (Successor Company), respectively, $731 for the period of June 1, 2018 to December 31, 2018 (Successor Company) and $546 for the period of January 1, 2018 to May 31, 2018 (Predecessor Company). In addition, the Company has reinsured a portion of the risk associated with U.S. variable annuities and the associated GMDB and GMWB riders.

In assessing the need for a valuation allowance, management considered future taxable temporary difference reversals, future taxable income exclusive of reversing temporary differences and carryovers, taxable income in open carry back years and other tax planning strategies. From time to time, tax planning strategies could include holding a portion of debt securities with market value losses until recovery, making investments which have specific tax characteristics and business considerations such as asset-liability matching.

Description of Regulatory Capital Requirements under Insurance Regulations		Dividends to the Company from its insurance subsidiaries and dividends from the Company to its parent are restricted by insurance regulation. The payment of dividends by Connecticut-domiciled insurers is limited under the insurance holding company laws of Connecticut. These laws require notice to and approval by the state insurance commissioner for the declaration or payment of any dividend, which, together with other dividends or distributions made within the preceding twelve months, exceeds the greater of (i) 10% of the insurer’s policyholder surplus as of December 31 of the preceding year or (ii) net income (or net gain from operations, if such company is a life insurance company) for the twelve-month period ending on the thirty-first day of December last preceding, in each case determined under statutory insurance accounting principles. In addition, if any dividend of a domiciled insurer exceeds the insurer’s earned surplus or certain other thresholds as calculated under applicable state insurance law, the dividend requires the prior approval of the domestic regulator. In addition to statutory limitations on paying dividends, the Company also takes other items into consideration when determining dividends from subsidiaries. These considerations include, but are not limited to, expected earnings and capitalization of the subsidiary, regulatory capital requirements and liquidity requirements of the individual operating company. As a condition of the sale, Talcott Resolution Life Insurance Company and its affiliates were required to gain pre-approval from the state insurance commissioner for any dividends, regardless of size, through May 31, 2020.
