Net Gains (Losses) Net gains (losses) comprise the difference between the amortized cost of investments and proceeds from sale and redemption, as well as losses incurred due to the credit-related and intent-related impairment of investments. Net gains (losses) are also primarily generated from changes in fair value of embedded derivatives within products and fixed maturities, changes in fair value of fixed maturities recorded at FVO and changes in fair value including accruals on derivative instruments, except for effective cash flow hedges.

Repurchase Agreements and Securities Pledged As of December 31, 2023 and 2022, the Company did not have any securities pledged in dollar rolls, repurchase agreement transactions or reverse repurchase agreements. The Company engages in securities lending whereby the initial collateral is required at a rate of 102% of the market value of the loaned securities. The lending agent retains the collateral and invests it in high quality liquid assets on behalf of the Company. The market value of the loaned securities is monitored on a daily basis with additional collateral obtained or refunded as the market value of the loaned securities fluctuates. The lending agent indemnifies the Company against losses resulting from the failure of a counterparty to return securities pledged where collateral is insufficient to cover the loss. In the normal course of business, the Company receives cash collateral and non-cash collateral in the form of securities. If cash is received as collateral, the lending agent retains the cash collateral and invests it in short-term liquid assets on behalf of the Company. Securities retained as collateral by the lending agent may not be sold or re-pledged, except in the event of default, and are not reflected on the Company’s Consolidated Balance Sheets. This collateral generally consists of U.S. Treasury, U.S. Government agency securities and MBS pools. The following table presents Securities pledged as of the dates indicated: December 31, 2023 December 31, 2022 Securities loaned to lending agent (1) $ 645 $ 690 Securities pledged as collateral (1)(2) 153 102 Total $ 798 $ 792 (1) Included in Securities pledged on the Consolidated Balance Sheets.

The Company's securities lending activities are conducted on an overnight basis, and all securities loaned can be recalled at any time. The Company does not offset assets and liabilities associated with its securities lending program. Allowance for credit losses The following table presents a rollforward of the allowance for credit losses on available-for-sale fixed maturity securities for the period presented: Year Ended December 31, 2023 Commercial mortgage-backed securities Foreign corporate public securities and foreign governments Foreign corporate private securities Other asset-backed securities Total Balance as of January 1, 2023 $ — $ 6 $ 1 $ — $ 7 Credit losses on securities for which credit losses were not previously recorded 9 — — 1 10 Reductions for securities sold during the period — (2) — — (2) Increase (decrease) on securities with allowance recorded in previous period — (1) — — (1) Balance as of December 31, 2023 $ 9 $ 3 $ 1 $ 1 $ 14 Year Ended December 31, 2022 Residential mortgage-backed securities Foreign corporate public securities and foreign governments Foreign corporate private securities Total Balance as of January 1, 2022 $ 1 $ — $ 47 $ 48 Credit losses on securities for which credit losses were not previously recorded — 6 — 6 Reductions for securities sold during the period — — (49) (49) Increase (decrease) on securities with allowance recorded in previous period (1) — 3 2 Balance as of December 31, 2022 $ — $ 6 $ 1 $ 7 For additional information about the Company’s methodology and significant inputs used in determining whether a credit loss exists, see the Business, Basis of Presentation and Significant Accounting Policies Note to these Consolidated Financial Statements. Unrealized Capital Losses The following table present available-for-sale fixed maturities, including securities pledged, for which an allowance for credit losses has not been recorded by investment category and duration as of the dates indicated: As of December 31, 2023 Twelve Months or Less More Than Twelve Months Below Amortized Cost Total Fair Unrealized Capital Losses Fair Unrealized Capital Losses Fair Unrealized Capital Losses U.S. Treasuries $ 60 $ 2 $ 105 $ 23 $ 165 $ 25 U.S. Government, agencies and authorities — — 17 2 17 2 State, municipalities and political subdivisions 16 — 528 70 544 70 U.S. corporate public securities 215 13 4,233 746 4,448 759 U.S. corporate private securities 128 5 2,653 251 2,781 256 Foreign corporate public securities and foreign governments 70 1 1,385 215 1,455 216 Foreign corporate private securities 151 4 1,744 101 1,895 105 Residential mortgage-backed 74 2 803 122 877 124 Commercial mortgage-backed 52 3 2,252 412 2,304 415 Other asset-backed 97 3 744 40 841 43 Total $ 863 $ 33 $ 14,464 $ 1,982 $ 15,327 $ 2,015 As of December 31, 2022 Twelve Months or Less More Than Twelve Months Total Fair Unrealized Capital Losses Fair Unrealized Capital Losses Fair Unrealized Capital Losses U.S. Treasuries $ 223 $ 30 $ 2 $ 1 $ 225 $ 31 U.S. Government, agencies and authorities 30 3 — — 30 3 State, municipalities and political subdivisions 545 85 15 7 560 92 U.S. corporate public securities 4,290 613 998 419 5,288 1,032 U.S. corporate private securities 2,819 264 331 64 3,150 328 Foreign corporate public securities and foreign governments 1,509 201 298 116 1,807 317 Foreign corporate private securities 2,203 173 52 11 2,255 184 Residential mortgage-backed 1,065 78 328 75 1,393 153 Commercial mortgage-backed 1,792 252 759 127 2,551 379 Other asset-backed 912 68 360 41 1,272 109 Total $ 15,388 $ 1,767 $ 3,143 $ 861 $ 18,531 $ 2,628 As of December 31, 2023, the average duration of our fixed maturities portfolio, including securities pledged, is between 6.5 and 7 years. As of December 31, 2023 and 2022, the Company concluded that an allowance for credit losses was not warranted for the securities above because the unrealized losses are interest rate related. The Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost bases. Evaluating Securities for Impairments The Company performs a regular evaluation, on a security-by-security basis, of its available-for-sale securities holdings, including fixed maturity securities, in accordance with its impairment policy in order to evaluate whether such investments are impaired. For the years ended December 31, 2023, 2022 and 2021 intent impairments included in the Consolidated Statements of Operations, but excluding impairments included in Other comprehensive income (loss), were $23, $17 and $2 respectively. The Company may sell securities during the period in which fair value has declined below amortized cost for fixed maturities. In certain situations, new factors, including changes in the business environment, can change the Company's previous intent to continue holding a security. Accordingly, these factors may lead the Company to record additional intent related capital losses. Debt Restructuring Upon the adoption of ASU 2022-02 as of January 1, 2023, the Company no longer identifies certain debt modifications as troubled debt restructuring, but instead evaluates all debt modifications to determine whether a modification results in a new loan or a continuation of an existing loan. Disclosures are required for loan modifications with borrowers experiencing financial difficulty. For the year ended December 31, 2023, the Company had no material debt modifications that require such disclosure. Mortgage Loans on Real Estate The Company diversifies its commercial mortgage loan portfolio by geographic region and property type to reduce concentration risk. The Company manages risk when originating commercial mortgage loans by generally lending only up to 75% of the estimated fair value of the underlying real estate. Subsequently, the Company continuously evaluates mortgage loans based on relevant current information including a review of loan-specific performance, property characteristics and market trends. Loan performance is monitored on a loan specific basis through the review of submitted appraisals, operating statements, rent revenues and annual inspection reports, among other items. This review ensures properties are performing at a consistent and acceptable level to secure the debt. The components to evaluate debt service coverage are received and reviewed at least annually to determine the level of risk. Loan-to-value ("LTV") and debt service coverage ("DSC") ratios are measures commonly used to assess the risk and quality of mortgage loans. The LTV ratio, calculated at time of origination, is expressed as a percentage of the amount of the loan relative to the value of the underlying property. A LTV ratio in excess of 100% indicates the unpaid loan amount exceeds the underlying collateral. The DSC ratio, based upon the most recently received financial statements, is expressed as a percentage of the amount of a property’s net income to its debt service payments. A DSC ratio of less than 1.0 indicates that a property’s operations do not generate sufficient income to cover debt payments. These ratios are utilized as part of the review process described above. The following tables present commercial mortgage loans by year of origination and LTV ratio as of the dates indicated. The information is updated as of December 31, 2023 and 2022, respectively.

Net Gains (Losses) Net gains (losses) comprise the difference between the amortized cost of investments and proceeds from sale and redemption, as well as losses incurred due to the credit-related and intent-related impairment of investments. Net gains (losses) are also primarily generated from changes in fair value of embedded derivatives within products and fixed maturities, changes in fair value of fixed maturities recorded at FVO and changes in fair value including accruals on derivative instruments, except for effective cash flow hedges. Net gains (losses) also include changes in fair value of trading debt securities and changes in fair value of equity securities. The cost of the investments on disposal is generally determined based on first-in-first-out ("FIFO") methodology.

("ISDA") agreements, the Company may receive from, or deliver to, counterparties, collateral to assure that terms of the ISDA agreements will be met with regard to the Credit Support Annex ("CSA"). The terms of the CSA call for the Company to pay interest on any cash received equal to the Federal Funds rate. To the extent cash collateral is received and delivered, it is included in Payables under securities loan agreements, including collateral held and Short-term investments under securities loan agreements, including collateral delivered, respectively, on the Consolidated Balance Sheets and is reinvested in short-term investments. Collateral held is used in accordance with the CSA to satisfy any obligations. Investment grade bonds owned by the Company are the source of noncash collateral posted, which is reported in Securities pledged on the Consolidated Balance Sheets. As of December 31, 2023, the Company held $17 and pledged $112 of net cash collateral related to OTC derivative contracts and cleared derivative contracts, respectively. As of December 31, 2022, the Company held $50 and $62 of net cash collateral related to OTC derivative contracts and cleared derivative contracts, respectively. In addition, as of December 31, 2023, the Company delivered $153 of securities and held $10 securities as collateral. As of December 31, 2022, the Company delivered $102 of securities and held $7 securities as collateral.

Valuation of Financial Assets and Liabilities at Fair Value Certain assets and liabilities are measured at estimated fair value on the Company's Consolidated Balance Sheets. The Company defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The exit price and the transaction (or entry) price will be the same at initial recognition in many circumstances. However, in certain cases, the transaction price may not represent fair value. The fair value of a liability is based on the amount that would be paid to transfer a liability to a third-party with an equal credit standing. Fair value is required to be a market-based measurement that is determined based on a hypothetical transaction at the measurement date, from a market participant's perspective. The Company considers three broad valuation approaches when a quoted price is unavailable: (i) the market approach, (ii) the income approach and (iii) the cost approach. The Company determines the most appropriate valuation technique to use, given the instrument being measured and the availability of sufficient inputs. The Company prioritizes the inputs to fair valuation approaches and allows for the use of unobservable inputs to the extent that observable inputs are not available. The Company utilizes a number of valuation methodologies to determine the fair values of its financial assets and liabilities in conformity with the concepts of exit price and the fair value hierarchy as prescribed in ASC Topic 820. Valuations are obtained from third-party commercial pricing services, brokers and industry-standard, vendor-provided software that models the value based on market observable inputs. The valuations obtained from third-party commercial pricing services are non-binding. The Company reviews the assumptions and inputs used by third-party commercial pricing services for each reporting period in order to determine an appropriate fair value hierarchy level. The documentation and analysis obtained from third-party commercial pricing services are reviewed by the Company, including in-depth validation procedures confirming the observability of inputs. The valuations are reviewed and validated monthly through the internal valuation committee price variance review, comparisons to internal pricing models, back testing to recent trades or monitoring of trading volumes. When available, the fair value of the Company's financial assets and liabilities are based on quoted prices of identical assets in active markets and therefore, reflected in Level 1. The valuation approaches and key inputs for each category of assets or liabilities that are classified within Level 2 and Level 3 of the fair value hierarchy are presented below. For fixed maturities classified as Level 2 assets, fair values are determined using a matrix-based market approach, based on prices obtained from third-party commercial pricing services and the Company’s matrix and analytics-based pricing models, which in each case incorporate a variety of market observable information as valuation inputs. The market observable inputs used for these fair value measurements, by fixed maturity asset class, are as follows: U.S. Treasuries: Fair value is determined using third-party commercial pricing services, with the primary inputs being stripped interest and principal U.S. Treasury yield curves that represent a U.S. Treasury zero-coupon curve. U.S. government agencies and authorities, State, municipalities and political subdivisions: Fair value is determined using third-party commercial pricing services, with the primary inputs being U.S. Treasury yield curves, trades of comparable securities, credit spreads off benchmark yields and issuer ratings. U.S. corporate public securities, Foreign corporate public securities and foreign governments: Fair value is determined using third-party commercial pricing services, with the primary inputs being benchmark yields, trades of comparable securities, issuer ratings, bids and credit spreads off benchmark yields. U.S. corporate private securities and Foreign corporate private securities: Fair values are determined using a matrix and analytics-based pricing model. The model incorporates the current level of risk-free interest rates, current corporate credit spreads, credit quality of the issuer and cash flow characteristics of the security. The model also considers a liquidity spread, the value of any collateral, the capital structure of the issuer, the presence of guarantees, and prices and quotes for comparably rated publicly traded securities. RMBS, CMBS and ABS: Fair value is determined using third-party commercial pricing services, with the primary inputs being credit spreads off benchmark yields, prepayment speed assumptions, current and forecasted loss severity, debt service coverage ratios, collateral type, payment priority within tranche and the vintage of the loans underlying the security. Generally, the Company does not obtain more than one vendor price from pricing services per instrument. The Company uses a hierarchy process in which prices are obtained from a primary vendor and, if that vendor is unable to provide the price, the next vendor in the hierarchy is contacted until a price is obtained or it is determined that a price cannot be obtained from a commercial pricing service. When a price cannot be obtained from a commercial pricing service, independent broker quotes are solicited. Securities priced using independent broker quotes are classified as Level 3. Fair values of privately placed bonds are determined primarily using a matrix-based pricing model and are generally classified as Level 2 assets. The model considers the current level of risk-free interest rates, current corporate spreads, the credit quality of the issuer and cash flow characteristics of the security. Also considered are factors such as the net worth of the borrower, the value of collateral, the capital structure of the borrower, the presence of guarantees and the Company's evaluation of the borrower's ability to compete in its relevant market. Using this data, the model generates estimated market values which the Company considers reflective of the fair value of each privately placed bond. Equity securities : Level 2 and Level 3 equity securities, typically private equities or equity securities not traded on an exchange, are valued by other sources such as analytics or brokers. Derivatives : Derivatives are carried at fair value, which is determined using the Company's derivative accounting system in conjunction with observable key financial data from third party sources, such as yield curves, exchange rates, S&P 500 Index prices, London Interbank Offered Rates ("LIBOR"), Overnight Index Swap ("OIS") rates, and Secured Overnight Financing Rate ("SOFR"). The Company uses SOFR discounting for valuations of interest rate derivatives; however, certain legacy positions may continue to be discounted on OIS. The Company uses OIS for valuations of collateralized interest rate derivatives, which are obtained from third-party sources. For those derivatives that are unable to be valued by the accounting system, the Company typically utilizes values established by third-party brokers. Counterparty credit risk is considered and incorporated in the Company's valuation process through counterparty credit rating requirements and monitoring of overall exposure. It is the Company's policy to transact only with investment grade counterparties with a credit rating of A- or better. The Company's nonperformance risk is also considered and incorporated in the Company's valuation process. The Company also has certain credit default swaps and options that are priced by third party vendors or by using models that primarily use market observable inputs, but contain inputs that are not observable to market participants, which have been classified as Level 3. The remaining derivative instruments are valued based on market observable inputs and are classified as Level 2. Stabilizer and MCGs: The Company records reserves for Stabilizer and MCG contracts containing guaranteed credited rates. The guarantee is treated as an embedded derivative or a stand-alone derivative (depending on the underlying product) and is required to be reported at fair value. The estimated fair value is determined based on the present value of projected future claims, minus the present value of future guaranteed premiums. At inception of the contract, the Company projects a guaranteed premium to be equal to the present value of the projected future claims. The income associated with the contracts is projected using relevant actuarial and capital market assumptions, including benefits and related contract charges, over the anticipated life of the related contracts. The cash flow estimates are produced by using stochastic techniques under a variety of risk neutral scenarios and other market implied assumptions. These derivatives are classified as Level 3 liabilities. The discount rate used to determine the fair value of the embedded derivatives and stand-alone derivative includes an adjustment for nonperformance risk. The nonperformance risk adjustment incorporates a blend of observable, similarly rated peer holding company credit spreads, adjusted to reflect the credit quality of the Company, as well as an adjustment to reflect the non-default spreads and the priority and recovery rates of policyholder claims. Level 3 Financial Instruments The fair values of certain assets and liabilities are determined using prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement (i.e., Level 3 as defined by ASC Topic 820), including but not limited to liquidity spreads for investments within markets deemed not currently active. These valuations, whether derived internally or obtained from a third-party, use critical assumptions that are not widely available to estimate market participant expectations in valuing the asset or liability. In addition, the Company has determined, for certain financial instruments, an active market is such a significant input to determine fair value that the presence of an inactive market may lead to classification in Level 3. In light of the methodologies employed to obtain the fair values of financial assets and liabilities classified as Level 3, additional information is presented below. The following table summarizes the change in fair value of the Company's Level 3 assets and liabilities and transfers in and out of Level 3 for the period indicated: Year Ended December 31, 2023 Fair Value Realized/Unrealized Purchases Issuances Sales Settlements Transfers into Level 3 Transfers out of Level 3 Fair Value as of December 31 Change in Unrealized Gains (Losses) Included in Earnings (3) Change in Unrealized Gains (Losses) Included in OCI (3) Net Income OCI Fixed maturities, including securities pledged: U.S. Corporate public securities $ 13 $ — $ — $ — $ — $ — $ — $ — $ — $ 13 $ — $ — U.S. Corporate private securities 1,356 — 20 109 — (3) (162) 57 (192) 1,185 1 18 Foreign corporate public securities and foreign governments (1) 2 — — — — — — — (2) — — — Foreign corporate private securities (1) 339 2 7 100 — (8) (125) 41 (2) 354 2 6 Residential mortgage-backed securities 20 (3) — 29 — — — 2 — 48 (3) — Other asset-backed securities 52 — — 10 — — (5) — (20) 37 — — Total fixed maturities, including securities pledged 1,782 (1) 27 248 — (11) (292) 100 (216) 1,637 — 24 Equity securities, at fair value 117 (3) — — — — (60) — — 54 — — Stabilizer and MCGs (2) (6) (1) — — (2) — — — — (9) — — Assets held in separate accounts (4) 347 1 — 8 — (21) — 14 (1) 348 — — (1) Primarily U.S. dollar denominated.

These amounts are included in Net gains (losses) in the Consolidated Statements of Operations. (3) The Company’s policy is to recognize transfers in and transfers out as of the beginning of the reporting period. (3) For financial instruments still held as of December 31, amounts are included in Net investment income and Net gains (losses) in the Consolidated Statements of Operations or Unrealized gains (losses) on securities in the Consolidated Statements of Comprehensive Income. (4) The investment income and realized gains (losses) and change in unrealized gains (losses) included in net income (loss) for separate account assets are offset by an equal amount for separate account liabilities, which results in a net zero impact on Net income (loss) for the Company. For the years ended December 31, 2023 and 2022, the transfers in and out of Level 3 for fixed maturities and separate accounts were due to the variation in inputs relied upon for valuation each quarter. Securities that are primarily valued using independent broker quotes when prices are not available from one of the commercial pricing services are reflected as transfers into Level 3. When securities are valued using more widely available information, the securities are transferred out of Level 3 and into Level 1 or 2, as appropriate. Other Financial Instruments The following disclosures are made in accordance with the requirements of ASC Topic 825 which requires disclosure of fair value information about financial instruments, whether or not recognized at fair value on the Consolidated Balance Sheets. ASC Topic 825 excludes certain financial instruments, including insurance contracts and all nonfinancial instruments from its disclosure requirements. Accordingly, the aggregate fair value amounts presented do not represent the underlying value of the Company.

Capital Contributions, Dividend

Capital Contributions, Dividends and Statutory Information	12 Months Ended

Equity [Abstract]
Capital Contributions, Dividends and Statutory Information	Capital Contributions, Dividends and Statutory Information Connecticut insurance law imposes restrictions on a Connecticut insurance company's ability to pay dividends to its parent. These restrictions are based in part on the prior year's statutory income and surplus. In general, dividends up to specified levels are considered ordinary and may be paid without prior approval. Dividends in larger amounts, or extraordinary dividends, are subject to approval by the Connecticut Insurance Commissioner. Under Connecticut insurance law, an extraordinary dividend or distribution is defined as a dividend or distribution that, together with other dividends or distributions made within the preceding twelve months, exceeds the greater of (1) ten percent (10%) of VRIAC's earned statutory surplus at the prior year end or (2) VRIAC's prior year statutory net gain from operations. Connecticut law also prohibits a Connecticut insurer from declaring or paying a dividend except out of its earned surplus unless prior insurance regulatory approval is obtained. During the year ended December 31, 2023, VRIAC declared and paid an ordinary dividend to its Parent in the aggregate amount of $310. During the year ended December 31, 2022, VRIAC declared and paid an ordinary dividend to its Parent in the aggregate amount of $48, as well as an extraordinary dividend in the aggregate amount of $809. During the years ended December 31, 2023 and 2022, VRIAC did not receive capital contributions from its Parent. The Company is subject to minimum risk-based capital ("RBC") requirements established by the Department. The formulas for determining the amount of RBC specify various weighting factors that are applied to financial balances or various levels of activity based on the perceived degree of risk. Regulatory compliance is determined by a ratio of total adjusted capital ("TAC"), as defined by the National Association of Insurance Commissioners ("NAIC"), to RBC requirements, as defined by the NAIC. The Company exceeded the minimum RBC requirements that would require any regulatory or corrective action for all periods presented herein. The Company is required to prepare statutory financial statements in accordance with statutory accounting practices prescribed or permitted by the Department. Statutory accounting practices primarily differ from U.S. GAAP by charging policy acquisition costs to expense as incurred, establishing future policy benefit liabilities using different actuarial assumptions as well as valuing investments and certain assets and accounting for deferred taxes on a different basis. Certain assets that are not admitted under statutory accounting principles are charged directly to surplus. Depending on the regulations of the Department, the entire amount or a portion of an insurance company's asset balance can be non-admitted depending on specific rules regarding admissibility. The most significant non-admitted assets of the Company are typically a portion of deferred tax assets in excess of prescribed thresholds. Statutory net income was $577, $549 and $794 for the years ended December 31, 2023, 2022 and 2021, respectively. Statutory capital and surplus was $2.0 billion and $1.8 billion for the years ended December 31, 2023 and 2022, respectively.

See the Business, Basis of Presentation and Significant Accounting Policies Note to these Consolidated Financial Statements for additional information The following table sets forth the federal and credit carryforwards for tax purposes as of the dates indicated: December 31, 2023 2022 Federal net operating loss carryforward $ 873 (1) $ 1,065 Credit carryforward 65 (2) 59 (1) NOL not subject to expiration (2) Expires between 2025 and 2032 Valuation allowances are provided when it is considered more likely than not that some portion or all of the deferred tax assets ("DTA") will not be realized. As of December 31, 2023 and 2022, the Company had no valuation allowance. However, the application of intra-period tax allocation rules to benefits associated with capital deferred tax assets resulted in a valuation allowance as of December 31, 2023 and 2022 of $128 and $128, respectively, in continuing operations, offset by a corresponding benefit in Other comprehensive income. The Company reviews all available positive and negative evidence to determine if a valuation allowance is recorded, including historical and projected pre-tax book income, tax planning strategies and reversals of temporary differences. As of December 31, 2023, the Company had year-to-date gains primarily on securities of $661 in Other comprehensive income, decreasing the related DTAs. Additionally, operating income remained positive for the period and was largely consistent with the 2022 year-end valuation allowance analysis. After evaluating the positive and negative evidence, the Company did not change its judgement regarding the realization of deferred tax assets and did not establish a valuation allowance in 2023. Other Tax Matters On January 4, 2021, Voya Financial completed a series of transactions pursuant to a Master Transaction Agreement ("MTA") with Resolution Life U.S. Holdings Inc. ("Resolution Life US"). As a part of these transactions, Resolution Life US acquired the Voya Financial's wholly owned subsidiary, Security Life of Denver Company ("SLD"). SLD generated capital losses in the 2022 tax year, which were included in a carryback claim for Voya Financial in accordance with the MTA and resulted in a $23 tax benefit to the Company and decrease to the effective tax rate (the "Security Life of Denver Company capital loss carryback"). Tax Sharing Agreement As of December 31, 2023 and 2022, the Company had a (payable)/receivable to/from Voya Financial of $(16) and $4, respectively, for federal income taxes under the intercompany tax sharing agreement. The results of the Company's operations are included in the consolidated tax return of Voya Financial. Generally, the Company's consolidated financial statements recognize the current and deferred income tax consequences that result from the Company's activities during the current and preceding periods pursuant to the provisions of Income Taxes (ASC 740) as if the Company were a separate taxpayer rather than a member of Voya Financial's consolidated income tax return group with the exception of any net operating loss carryforwards and capital loss carryforwards, which are recorded pursuant to the tax sharing agreement. If the Company instead were to follow a separate taxpayer approach without any exceptions, there would be no impact to income tax expense (benefit) for the periods indicated above. However, any current tax benefit related to the Company's tax attributes realized by virtue of its inclusion in the consolidated tax return of Voya Financial would have been recorded directly to equity rather than income. Under the tax sharing agreement, Voya Financial will pay the Company for the tax benefits of ordinary and capital losses only in the event that the consolidated tax group actually uses the tax benefit of losses generated. Unrecognized Tax Benefits The Company had no unrecognized tax benefits as of December 31, 2023 and 2022. Interest and Penalties The Company recognizes accrued interest and penalties related to unrecognized tax benefits in current income taxes and Income tax expense on the Consolidated Balance Sheets and the Consolidated Statements of Operations, respectively. The Company had no accrued interest as of December 31, 2023 and 2022. Tax Regulatory Matters For the tax years 2021 through 2023, the Company participated in the Internal Revenue Service ("IRS") Compliance Assurance Process ("CAP"), which is a continuous audit program provided by the IRS. For the 2023 tax year, the Company was in the Compliance Maintenance Bridge ("Bridge") phase of CAP. In the Bridge phase, the IRS did not conduct any review or provide any letters of assurance for that tax year. Tax Legislative Matters

Benefit Plans

Benefit Plans	12 Months Ended

Retirement Benefits [Abstract]
Benefit Plans	Benefit Plans Defined Benefit Plan Voya Services Company sponsors the Voya Retirement Plan (the "Retirement Plan"). Substantially all employees of Voya Services Company and its affiliates (excluding certain employees) are eligible to participate. The Retirement Plan is a tax qualified defined benefit plan, the benefits of which are guaranteed (within certain specified legal limits) by the Pension Benefit Guaranty Corporation (“PBGC”). Beginning January 1, 2012, the Retirement Plan adopted a cash balance pension formula instead of a final average pay ("FAP") formula, allowing all eligible employees to participate in the Retirement Plan. Participants will earn an annual credit equal to 4% of eligible compensation. Interest is credited monthly based on a 30-year U.S. Treasury securities bond rate published by the Internal Revenue Service in the preceding August of each year. The accrued vested cash pension balance benefit is portable; participants can take it if they leave the Company. The costs allocated to the Company for its employees' participation in the Retirement Plan were $12, $14 and $13 for the years ended December 31, 2023, 2022 and 2021, respectively, and are included in Operating expenses in the Consolidated Statements of Operations. Defined Contribution Plan Voya Services Company sponsors the Voya Savings Plan (the "Savings Plan"). Substantially all employees of Voya Services Company and its affiliates (excluding certain employees, including but not limited to Career Agents) are eligible to participate, including the Company's employees other than Company agents. Career Agents are certain, full-time insurance salespeople who have entered into a career agent agreement with the Company and certain other individuals who meet specified eligibility criteria ("Career Agents"). The Savings Plan is a tax qualified defined contribution plan. Savings Plan benefits are not guaranteed by the PBGC. The Savings Plan allows eligible participants to defer into the Savings Plan a specified percentage of eligible compensation on a pre-tax basis. Voya Services Company matches such pre-tax contributions, up to a maximum of 6% of eligible compensation. Matching contributions are subject to a 4-year graded vesting schedule. Contributions made to the Savings Plan are subject to certain limits imposed by applicable law. The costs allocated to the Company for the Savings Plan were $21, $19 and $18, for the years ended December 31, 2023, 2022 and 2021, respectively, and are included in Operating expenses in the Consolidated Statements of Operations. Non-Qualified Retirement Plans The Company, in conjunction with Voya Services Company, offers certain eligible employees (other than Career Agents) a Supplemental Executive Retirement Plan and an Excess Plan (collectively, the "SERPs"). Benefit accruals under Aetna Financial Services SERPs ceased, effective as of December 31, 2001 and participants began accruing benefits under Voya Services SERPs. Benefits under the SERPs are determined based on an eligible employee's years of service and average annual compensation for the highest five years during the last ten years of employment. Effective January 1, 2012, the Supplemental Executive Retirement Plan was amended to coordinate with the amendment of the Retirement Plan from its current final average pay formula to a cash balance formula. The Company, in conjunction with Voya Services Company, sponsors the Pension Plan for Certain Producers of Voya Retirement Insurance and Annuity Company (the "Agents Non-Qualified Plan"). This plan covers Career Agents. The Agents Non-Qualified Plan was frozen effective January 1, 2002. In connection with the termination, all benefit accruals ceased and all accrued benefits were frozen. The SERPs and Agents Non-Qualified Plan are non-qualified defined benefit pension plans, which means all the SERPs benefits are payable from the general assets of the Company and Agents Non-Qualified Plan benefits are payable from the general assets of the Company and Voya Services Company. These non-qualified defined benefit pension plans are not guaranteed by the PBGC. Obligations and Funded Status The following table summarizes the benefit obligations for the SERPs and Agents Non-Qualified Plan as of December 31, 2023 and 2022: Year Ended December 31, 2023 2022 Change in benefit obligation: Benefit obligation, January 1 $ 61 $ 78 Interest cost 3 2 Benefits paid (5) (6) Actuarial (gains) losses on obligation 1 (13) Benefit obligation, December 31 $ 60 $ 61 (1) Includes actuarial loss of $1 due to change in discount rate for the year ended December 31, 2023. The discount rate decreased 0.19% during 2023 driven by a decrease in corporate AA yields. Amounts recognized on the Consolidated Balance Sheets in Other liabilities and in AOCI were as follows as of December 31, 2023 and 2022: December 31, 2023 2022 Accrued benefit cost $ (60) $ (61) Net amount recognized $ (60) $ (61) (1) Accrued benefit cost is included in Other liabilities on the Consolidated Balance Sheets. Assumptions The discount rate used in the measurement of the December 31, 2023 and 2022 benefit obligation for the SERPs and Agents Non-Qualified Plan, were as follows: 2023 2022 Discount rate 5.28 % 5.47 % In determining the discount rate assumption, the Company utilizes current market information provided by its plan actuaries, including a discounted cash flow analysis of the Company's pension obligation and general movements in the current market environment. The discount rate modeling process involves selecting a portfolio of high quality, noncallable bonds that will match the cash flows of the SERPs and Agents Non-Qualified Plan. The weighted-average discount rate used in calculating the net pension cost was as follows: 2023 2022 2021 Discount rate 5.47 % 3.00 % 2.67 % Since the benefit plans of the Company are unfunded, an assumption for return on plan assets is not required. Net Periodic Benefit Costs Net periodic benefit costs for the SERPs and Agents Non-Qualified Plan were as follows for the years ended December 31, 2023, 2022 and 2021: Year Ended December 31, 2023 2022 2021 Interest cost $ 3 $ 2 $ 2 Net (gain) loss recognition 1 (13) (3) Net periodic (benefit) cost $ 4 $ (11) $ (1) Expected Future Benefit Payments The following table summarizes the expected benefit payments related to the SERPs and Agents Non-Qualified Plan for the years indicated: 2024 $ 6 2025 6 2026 6 2027 5 2028 5 2029-2033 23 In 2024, the Company is expected to contribute $6 to the SERPs and Agents Non-Qualified Plan. Share Based Compensation Plans Certain employees of the Company participate in the 2013, 2014 and 2019 Omnibus Employee Incentive Plans ("the Omnibus Plans") sponsored by Voya Financial. The Omnibus Plans each permit the granting of a wide range of equity-based awards, including restricted stock units ("RSUs"), performance share units ("PSUs"), and stock options. The Company was allocated compensation expense from Voya Financial of $34, $35 and $34 for the years ended December 31, 2023, 2022 and 2021, respectively. The Company recognized tax benefits of $7, $8 and $8 for the years ended 2023, 2022 and 2021, respectively. All excess tax benefits and tax deficiencies related to share-based compensation are reported in Net Income. Other Benefit Plans In addition, the Company, in conjunction with Voya Services Company, sponsors the following benefit plans: • The Voya 401(k) Plan for VRIAC Agents, which allows participants to defer a specified percentage of eligible compensation on a pre-tax basis. Effective January 1, 2006, the Company match equals 60% of a participant's pre-tax deferral contribution, with a maximum of 6% of the participant's eligible pay. A request for a determination letter on the qualified status of the Voya 401(k) Plan for VRIAC Agents was filed with the IRS on January 1, 2014. A favorable determination letter was received dated August 28, 2014. • The Producers' Incentive Savings Plan, which allows participants to defer up to a specified portion of their eligible compensation on a pre-tax basis. The Company matches such pre-tax contributions at specified amounts. • The Producers' Deferred Compensation Plan, which allows participants to defer up to a specified portion of their eligible compensation on a pre-tax basis. • Certain health care and life insurance benefits for retired employees and their eligible dependents. The postretirement health care plan is contributory, with retiree contribution levels adjusted annually and the Company subsidizes a portion of the monthly per-participant premium. Prior to April 1, 2017, coverage for Medicare eligible retirees was provided through a fully insured Medicare Advantage plan. Effective April 1, 2017, the fully insured Medicare Advantage Plan was replaced with access to individual coverage through a private exchange. The Company's premium subsidy ended and was replaced with a monthly HRA contribution. The Company continues to offer access to medical coverage until retirees become eligible for Medicare. The life insurance plan provides a flat amount of noncontributory coverage and optional contributory coverage. • The Voya Financial Deferred Compensation Savings Plan, which is a non-qualified deferred compensation plan that includes a 401(k) excess component. The benefit charges incurred by the Company related to these plans were immaterial for the years ended December 31, 2023, 2022, and 2021.

Financing Agreements

Financing Agreements	12 Months Ended

Debt Disclosure [Abstract]
Financing Agreements	Reciprocal Loan Agreement The Company maintains a reciprocal loan agreement with Voya Financial, an affiliate, to facilitate the handling of unanticipated short-term cash requirements that arise in the ordinary course of business. Under this agreement, which became effective in June 2001 and expires on April 1, 2026, either party can borrow from the other up to 3.0% of the Company's statutory admitted assets as of the preceding December 31. During the years ended December 31, 2023, 2022, and 2021, interest on any borrowing by either the Company or Voya Financial was charged at a rate based on the prevailing market rate for similar third-party borrowings for securities.

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Leases All of the Company's expenses for leased and subleased office properties are paid for by an affiliate and allocated back to the Company, as all remaining operating leases were executed by Voya Services Company as of December 31, 2008, which resulted in the Company no longer being party to any operating leases. For the years ended December 31, 2023, 2022 and 2021, rent expense for leases was $2, $3 and $3, respectively. Commitments Through the normal course of investment operations, the Company commits to either purchase or sell securities, mortgage loans, or money market instruments, at a specified future date and at a specified price or yield. The inability of counterparties to honor these commitments may result in either a higher or lower replacement cost. Also, there is likely to be a change in the value of the securities underlying the commitments. As of December 31, 2023 the Company had off-balance sheet commitments to acquire mortgage loans of $56 and purchase limited partnerships and private placement investments of $689. Restricted Assets The Company is required to maintain assets on deposit with various regulatory authorities to support its insurance operations. The Company may also post collateral in connection with certain securities lending, repurchase agreements, funding agreements, letter of credit ("LOC") and derivative transactions as described further in this note. The components of the fair value of the restricted assets were as follows as of the dates indicated: December 31, 2023 2022 Fixed maturity collateral pledged to FHLB (1) $ 1,205 $ 997 FHLB restricted stock (2) 33 35 Other fixed maturities-state deposits 11 11 Cash and cash equivalents 2 2 Securities pledged (3) 798 792 Total restricted assets $ 2,049 $ 1,837 (1) Included in Fixed maturities, available for sale, at fair value, on the Consolidated Balance Sheets. (2) Included in Other investments on the Consolidated Balance Sheets. (3) Includes the fair value of loaned securities of $645 and $690 as of December 31, 2023 and 2022, respectively. In addition, as of December 31, 2023 and 2022, the Company delivered securities as collateral of $153 and $102, respectively. Loaned securities and securities delivered as collateral are included in Securities pledged on the Consolidated Balance Sheets. Federal Home Loan Bank Funding The Company is a member of the Federal Home Loan Bank of Boston (“FHLB”) and is required to pledge collateral to back funding agreements issued to the FHLB. As of December 31, 2023 and 2022, the Company had $671 and $730, respectively, in non-putable funding agreements, which are included in Future policy benefits and contract owner account balances on the Consolidated Balance sheets. As of December 31, 2023 and 2022, assets with a market value of approximately $1,205 and $997, respectively, collateralized the FHLB funding agreements. Assets pledged to the FHLB are included in Fixed maturities, available for sale, at fair value on the Consolidated Balance Sheets. Litigation, Regulatory Matters and Loss Contingencies Litigation, regulatory and other loss contingencies arise in connection with the Company's activities as a diversified financial services firm. The Company is a defendant in a number of litigation matters arising from the conduct of its business, both in the ordinary course and otherwise. In some of these matters, claimants seek to recover very large or indeterminate amounts, including compensatory, punitive, treble and exemplary damages. Modern pleading practice in the U.S. permits considerable variation in the assertion of monetary damages and other relief. Claimants are not always required to specify the monetary damages they seek or they may be required only to state an amount sufficient to meet a court's jurisdictional requirements. Moreover, some jurisdictions allow claimants to allege monetary damages that far exceed any reasonably possible verdict. The variability in pleading requirements and past experience demonstrates that the monetary and other relief that may be requested in a lawsuit or claim often bears little relevance to the merits or potential value of a claim. Litigation against the Company includes a variety of claims including negligence, breach of contract, fraud, violation of regulation or statute, breach of fiduciary duty, negligent misrepresentation, failure to supervise, elder abuse and other torts. As with other financial services companies, the Company periodically receives informal and formal requests for information from various state and federal governmental agencies and self-regulatory organizations in connection with inquiries and investigations of the products and practices of the Company or the financial services industry. It is the practice of the Company to cooperate fully in these matters. The outcome of a litigation or regulatory matter is difficult to predict and the amount or range of potential losses associated with these or other loss contingencies requires significant management judgment. It is not possible to predict the ultimate outcome or to provide reasonably possible losses or ranges of losses for all pending regulatory matters, litigation and other loss contingencies. While it is possible that an adverse outcome in certain cases could have a material adverse effect upon the Company's financial position, based on information currently known, management believes that neither the outcome of pending litigation and regulatory matters, nor potential liabilities associated with other loss contingencies, are likely to have such an effect. However, given the large and indeterminate amounts sought in certain litigation and the inherent unpredictability of all such matters, it is possible that an adverse outcome in certain of the Company's litigation or regulatory matters, or liabilities arising from other loss contingencies, could, from time to time, have a material adverse effect upon the Company's results of operations or cash flows in a particular quarterly or annual period. For some matters, the Company is able to estimate a possible range of loss. For such matters in which a loss is probable, an accrual has been made. For matters where the Company, however, believes a loss is reasonably possible, but not probable, no accrual is required. For matters for which an accrual has been made, but there remains a reasonably possible range of loss in excess of the amounts accrued or for matters where no accrual is required, the Company develops an estimate of the unaccrued amounts of the reasonably possible range of losses. As of December 31, 2023, the Company estimates the aggregate range of reasonably possible losses, in excess of any amounts accrued for these matters as of such date, as not material to the Company. For other matters, the Company is currently not able to estimate the reasonably possible loss or range of loss. The Company is often unable to estimate the possible loss or range of loss until developments in such matters have provided sufficient information to support an assessment of the range of possible loss, such as quantification of a damage demand from plaintiffs, discovery from plaintiffs and other parties, investigation of factual allegations, rulings by a court on motions or appeals, analysis by experts and the progress of settlement discussions. On a quarterly and annual basis, the Company reviews relevant information with respect to litigation and regulatory contingencies and updates the Company's accruals, disclosures and reasonably possible losses or ranges of loss based on such reviews. Litigation includes Ravarino, et al. v. Voya Financial, Inc., et al. (USDC District of Connecticut, No. 3:21-cv-01658)(filed December 14, 2021). In this putative class action, the plaintiffs allege that the named defendants, which include the Company, breached their fiduciary duties of prudence and loyalty in the administration of the Voya 401(k) Savings Plan. The plaintiffs claim that the named defendants did not exercise proper prudence in their management of allegedly poorly performing investment options, including proprietary funds, and passed excessive investment-management and other administrative fees for proprietary and non-proprietary funds onto plan participants. The plaintiffs also allege that the defendants engaged in self-dealing through the inclusion of the Voya Stable Value Option into the plan offerings and by setting the “crediting rate” for participants’ investment in the Stable Value Fund artificially low in relation to Voya’s general account investment returns in order to maximize the spread and Voya’s profits at the participants’ expense. The complaint seeks disgorgement of unjust profits as well as costs incurred. On June 13, 2023, the Court issued a ruling granting in part and denying in part Voya's motion to dismiss. The court largely dismissed the claims for breach of fiduciary duty. The remaining claims concern allegations of breaches of the ERISA prohibited transactions rule and a claim for failure to monitor the Voya Small Cap Growth fund. The Company denies the allegations, which it believes are without merit, and intends to defend the case vigorously.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying Consolidated Financial Statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP").
Estimates and Assumptions	Significant Accounting Policies Estimates and Assumptions The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting period. Those estimates are inherently subject to change and actual results could differ from those estimates, and the differences may be material to the Consolidated Financial Statements. The Company has identified the following accounts and policies as the most significant in that they involve a higher degree of judgment, are subject to a significant degree of variability or contain significant accounting estimates: • Valuation of investments and derivatives; • Investment impairments; • Income taxes; and •
Fair Value Measurement	Fair Value Measurement The Company measures the fair value of its financial assets and liabilities based on assumptions used by market participants in pricing the asset or liability, which may include inherent risk, restrictions on the sale or use of an asset, or nonperformance risk, including the Company's own credit risk. The estimate of fair value is the price that would be received to sell an asset or transfer a liability ("exit price") in an orderly transaction between market participants in the principal market, or the most advantageous market in the absence of a principal market, for that asset or liability. The Company uses a number of valuation sources to determine the fair values of its financial assets and liabilities, including quoted market prices, third-party commercial pricing services, third-party brokers, industry-standard, vendor-provided software that models the value based on market observable inputs, and other internal modeling techniques based on projected cash flows.
Investments	The Company's fixed maturities are generally designated as available-for-sale. In addition, the Company has fixed maturities accounted for using the fair value option ("FVO"). Available-for-sale securities are reported at fair value and unrealized capital gains (losses) on these securities are recorded directly in Accumulated other comprehensive income ("AOCI") and presented net of Deferred income taxes. Trading securities are valued at fair value, with the changes in fair value recorded in Net gains (losses) and interest income recorded in Net investment income in the Consolidated Statements of Operations. In addition, certain fixed maturities have embedded derivatives, which are reported with the host contract on the Consolidated Balance Sheets. Certain collateralized mortgage obligations ("CMOs"), primarily interest-only and principal-only strips, are accounted for as hybrid instruments and valued at fair value with changes in the fair value recorded in Net gains (losses). Changes in fair value associated with derivatives purchased to hedge CMOs are also recorded in Net gains (losses). Purchases and sales of fixed maturities and equity securities, excluding private placements, are recorded on the trade date. Purchases and sales of private placements and mortgage loans are recorded on the closing date. Investment gains and losses on sales of securities are generally determined on a first-in-first-out ("FIFO") basis. Interest income on fixed maturities is recorded when earned using an effective yield method, giving effect to amortization of premiums and accretion of discounts. Dividends on equity securities are recorded when declared. Such dividends and interest income are recorded in Net investment income. Included within fixed maturities are loan-backed securities, including residential mortgage-backed securities ("RMBS"), commercial mortgage-backed securities ("CMBS") and asset-backed securities ("ABS"). Amortization of the premium or discount from the purchase of these securities considers the estimated timing and amount of prepayments of the underlying loans. Actual prepayment experience is periodically reviewed and effective yields are recalculated when differences arise between the prepayments originally anticipated and the actual prepayments received and currently anticipated. Prepayment assumptions for single-class and multi-class mortgage-backed securities ("MBS") and ABS are estimated by management using inputs obtained from third-party specialists, including broker-dealers, and based on management's knowledge of the current market. For prepayment-sensitive securities such as interest-only and principal-only strips, inverse floaters and credit-sensitive MBS and ABS securities, which represent beneficial interests in securitized financial assets that are not of high credit quality or that have been credit impaired, the effective yield is recalculated on a prospective basis. For all other MBS and ABS, the effective yield is recalculated on a retrospective basis. Short-term Investments : Short-term investments include investments with remaining maturities of one year or less, but greater than three months, at the time of purchase. These investments are stated at fair value. Mortgage Loans on Real Estate : The Company's mortgage loans on real estate are all commercial mortgage loans, which are reported at amortized cost, net of allowance for credit losses. Amortized cost is the principal balance outstanding, net of deferred loan fees and costs. Accrued interest receivable is reported in Accrued investment income on the Consolidated Balance Sheets. Mortgage loans are evaluated by the Company's investment professionals, including an appraisal of loan-specific credit quality, property characteristics and market trends. Loan performance is continuously monitored on a loan-specific basis throughout the year. The Company's review includes submitted appraisals, operating statements, rent revenues and annual inspection reports, among other items. This review evaluates whether the properties are performing at a consistent and acceptable level to secure the debt. Management estimates the credit loss allowance balance using a factor-based method of probability of default and loss given default which incorporates relevant available information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. Included in the factor-based method are the consideration of debt type, capital market factors, and market vacancy rates, and loan-specific risk characteristics such as debt service coverage ratios (“DSC”), loan-to-value (“LTV”), collateral size, seniority of the loan, segmentation, and property types. The allowance for credit losses is a valuation account that is deducted from the loans’ amortized cost basis to present the net amount expected to be collected on the loans. The change in the allowance for credit losses is recorded in Net gains (losses). Loans are written off against the allowance when management believes the uncollectability of a loan balance is confirmed. Expected recoveries do not exceed the aggregate of amounts previously written-off and expected to be written-off. Mortgages are rated for the purpose of quantifying the level of risk. Those loans with higher risk are placed on a watch list and are closely monitored for collateral deficiency or other credit events that may lead to a potential loss of principal or interest. The Company defines delinquent mortgage loans consistent with industry practice as 60 days past due. Commercial mortgage loans are placed on non-accrual status when 90 days in arrears if the Company has concerns regarding the collectability of future payments, or if a loan has matured without being paid off or extended. Factors considered may include conversations with the borrower, loss of major tenant, bankruptcy of borrower or major tenant, decreased property cash flow, number of days past due, or various other circumstances. Based on an assessment as to the collectability of the principal, a determination is made either to apply against the book value or apply according to the contractual terms of the loan. Funds recovered in excess of book value would then be applied to recover expenses, impairments, and then interest. Accrual of interest resumes after factors resulting in doubts about collectability have improved. For those mortgages that are determined to require foreclosure, expected credit losses are based on the fair value of the underlying collateral, net of estimated costs to obtain and sell at the point of foreclosure. Property obtained from foreclosed mortgage loans is recorded in Other investments on the Consolidated Balance Sheets. Policy Loans : Policy loans are carried at an amount equal to the unpaid balance. Interest income on such loans is recorded as earned in Net investment income using the contractually agreed upon interest rate. Generally, interest is capitalized on the policy's anniversary date. Valuation allowances are not established for policy loans, as these loans are collateralized by the cash surrender value of the associated insurance contracts. Any unpaid principal or interest on the loan is deducted from the account value or the death benefit prior to settlement of the policy. Limited Partnerships/Corporations : The Company uses the equity method of accounting for investments in limited partnership interests, which consist primarily of private equity and hedge funds. Generally, the Company records its share of earnings using a lag methodology, relying on the most recent financial information available, typically not to exceed three months. The Company's earnings from limited partnership interests accounted for under the equity method are recorded in Net investment income. Other Investments : Other investments are comprised primarily of the Company's investment in outstanding common stock of an affiliate, Voya Special Investments, Inc., which is accounted for as an equity method investment. Other investments also include Federal Home Loan Bank ("FHLB") stock and property obtained from foreclosed mortgage loans, as well as other miscellaneous investments. The Company is a member of the FHLB system and is required to own a certain amount of FHLB stock based on the level of borrowings and other factors. FHLB stock is carried at cost, classified as a restricted security and periodically evaluated for impairment based on ultimate recovery of par value. Securities Pledged : The Company engages in securities lending whereby certain securities from its portfolio are loaned to other institutions, through a lending agent, for short periods of time. The Company has the right to approve any institution with whom the lending agent transacts on its behalf. Initial collateral, primarily cash, is required at an agreed-upon percentage of the market value of the loaned securities. The lending agent retains the collateral and invests it in short-term liquid assets on behalf of the Company. The market value of the loaned securities is monitored on a daily basis with additional collateral obtained or refunded as the market value of the loaned securities fluctuates. The lending agent indemnifies the Company against losses resulting from the failure of a counterparty to return securities pledged where collateral is insufficient to cover the loss. See also Repurchase Agreements below. Investment Impairments The Company evaluates its available-for-sale investments quarterly to determine whether a decline in fair value below the amortized cost basis has resulted from credit loss or other factors. This evaluation process entails considerable judgment and estimation. Factors considered in this analysis include, but are not limited to, the extent to which the fair value has been less than amortized cost, the issuer's financial condition and near-term prospects, future economic conditions and market forecasts, interest rate changes and changes in ratings of the security. A severe unrealized loss position on a fixed maturity may not have any impact on (a) the ability of the issuer to service all scheduled interest and principal payments and (b) the evaluation of recoverability of all contractual cash flows or the ability to recover an amount at least equal to its amortized cost based on the present value of the expected future cash flows to be collected. When assessing the Company's intent to sell a security, or if it is more likely than not it will be required to sell a security before recovery of its amortized cost basis, management evaluates facts and circumstances such as, but not limited to, decisions to rebalance the investment portfolio and sales of investments to meet cash flow or capital needs. When the Company has determined it has the intent to sell, or if it is more likely than not that the Company will be required to sell a security before recovery of its amortized cost basis, and the fair value has declined below amortized cost ("intent impairment"), the individual security is written down from amortized cost to fair value, and a corresponding charge is recorded in Net gains (losses) as impairments in the Consolidated Statements of Operations. For available-for-sale securities that do not meet the intent impairment criteria but the Company has determined that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss allowance is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in Other comprehensive income (loss). The Company uses the following methodology and significant inputs in determining whether a credit loss exists: • When determining collectability and the period over which the value is expected to recover for U.S. and foreign corporate securities, foreign government securities and state and political subdivision securities, the Company applies the same considerations utilized in its overall impairment evaluation process, which incorporates information regarding the specific security, the industry and geographic area in which the issuer operates and overall macroeconomic conditions. Projected future cash flows are estimated using assumptions derived from the Company's best estimates of likely scenario-based outcomes, after giving consideration to a variety of variables that includes, but is not limited to: general payment terms of the security; the likelihood that the issuer can service the scheduled interest and principal payments; the quality and amount of any credit enhancements; the security's position within the capital structure of the issuer; possible corporate restructurings or asset sales by the issuer; and changes to the rating of the security or the issuer by rating agencies. • Additional considerations are made when assessing the unique features that apply to certain structured securities, such as subprime, Alt-A, non-agency RMBS, CMBS and ABS. These additional factors for structured securities include, but are not limited to: the quality of underlying collateral; expected prepayment speeds; loan-to-value ratios; debt service coverage ratios; current and forecasted loss severity; consideration of the payment terms of the underlying assets backing a particular security; and the payment priority within the tranche structure of the security. • When determining the amount of the credit loss for U.S. and foreign corporate securities, foreign government securities and state and political subdivision securities, the Company considers the estimated fair value as the recovery value when available information does not indicate that another value is more appropriate. When information is identified that indicates a recovery value other than estimated fair value, the Company considers in the determination of recovery value the same considerations utilized in its overall impairment evaluation process, which incorporates available information and the Company's best estimate of scenario-based outcomes regarding the specific security and issuer; possible corporate restructurings or asset sales by the issuer; the quality and amount of any credit enhancements; the security's position within the capital structure of the issuer; fundamentals of the industry and geographic area in which the security issuer operates; and the overall macroeconomic conditions. • The Company performs a discounted cash flow analysis comparing the current amortized cost of a security to the present value of future cash flows expected to be received, including estimated defaults and prepayments. The discount rate is generally the effective interest rate of the fixed maturity prior to impairment. Changes in the allowance for credit losses are recorded in Net gains (losses) as impairments. Losses are charged against the allowance when the Company believes the uncollectability of an available-for-sale security is confirmed or when either of the criteria regarding intent or requirement to sell is met.
Derivatives	Derivatives The Company's use of derivatives is limited mainly to economic hedging to reduce the Company's exposure to cash flow variability of assets and liabilities, interest rate risk, credit risk, exchange rate risk and market risk. It is the Company's policy not to offset amounts recognized for derivative instruments and amounts recognized for the right to reclaim cash collateral or the obligation to return cash collateral arising from derivative instruments executed with the same counterparty under a master netting arrangement, which provides the Company with the legal right of offset. However, in accordance with the Chicago Mercantile Exchange ("CME") rules related to the variation margin payments, the Company is required to adjust the derivative balances with the variation margin payments related to its cleared derivatives executed through CME. The Company enters into interest rate, equity market, credit default and currency contracts, including swaps, futures, forwards, caps, floors and options, to reduce and manage various risks associated with changes in value, yield, price, cash flow or exchange rates of assets or liabilities held or intended to be held, or to assume or reduce credit exposure associated with a referenced asset, index or pool. The Company also utilizes options and futures on equity indices to reduce and manage risks associated with its annuity products. Derivative contracts are reported as Derivatives assets or liabilities on the Consolidated Balance Sheets at fair value. Changes in the fair value of derivatives are recorded in Net gains (losses) in the Consolidated Statements of Operations. Gains (losses) and net investment income related to derivatives are reflected as adjustments to reconcile Net cash flows from operating activities, and the net cash activity from derivatives is reflected in Net cash flows from investing activities, in the Consolidated Statements of Cash Flows. Any noncash activity, to the extent it is material, is excluded and reflected in a noncash supplementary schedule related to investing and financing activities. To qualify for hedge accounting, at the inception of the hedging relationship, the Company formally documents its risk management objective and strategy for undertaking the hedging transaction, as well as its designation of the hedge as either (a) a hedge of the exposure to changes in the estimated fair value of a recognized asset or liability or an identified portion thereof that is attributable to a particular risk ("fair value hedge") or (b) a hedge of a forecasted transaction or of the variability of cash flows that is attributable to interest rate risk to be received or paid related to a recognized asset or liability ("cash flow hedge"). In this documentation, the Company sets forth how the hedging instrument is expected to hedge the designated risks related to the hedged item and sets forth the method that will be used to retrospectively and prospectively assess the hedging instrument's effectiveness and the method that will be used to measure ineffectiveness. A derivative designated as a hedging instrument must be assessed as being highly effective in offsetting the designated risk of the hedged item. Hedge effectiveness is formally assessed at inception and periodically throughout the life of the designated hedging relationship. • Fair Value Hedge : For derivative instruments that are designated and qualify as a fair value hedge, the entire change in the fair value of the hedging instrument included in the assessment of hedge effectiveness is recorded in the same line item in the Consolidated Statements of Operations as impacted by the hedged item. • Cash Flow Hedge : For derivative instruments that are designated and qualify as a cash flow hedge, the entire change in the fair value of the hedging instrument included in the assessment of hedge effectiveness is reported as a component of AOCI. Those amounts are subsequently reclassified to earnings when the hedged item affects earnings, and are reported in the same line item in the Consolidated Statements of Operations as impacted by the hedged item. Even if a derivative qualifies for hedge accounting treatment, there may be an element of ineffectiveness of the hedge. The ineffective portion of a hedging relationship subject to hedge accounting is recognized in Net gains (losses). When hedge accounting is discontinued because it is determined that the derivative is no longer expected to be highly effective in offsetting changes in the estimated fair value or cash flows of a hedged item, the derivative continues to be carried on the Consolidated Balance Sheets at its estimated fair value, with subsequent changes in estimated fair value recognized currently in Net gains (losses). The carrying value of the hedged asset or liability under a fair value hedge is no longer adjusted for changes in its estimated fair value due to the hedged risk, and the cumulative adjustment to its carrying value is amortized into income over the remaining life of the hedged item. Provided the hedged forecasted transaction is still probable of occurrence, the changes in estimated fair value of derivatives recorded in Other comprehensive income (loss) related to discontinued cash flow hedges are released into the Consolidated Statements of Operations when the Company's earnings are affected by the variability in cash flows of the hedged item. When hedge accounting is discontinued because it is no longer probable that the forecasted transactions will occur on the anticipated date, or within two months of that date, the derivative continues to be carried on the Consolidated Balance Sheets at its estimated fair value, with changes in estimated fair value recognized currently in Net gains (losses). Derivative gains and losses recorded in Other comprehensive income (loss) pursuant to the discontinued cash flow hedge of a forecasted transaction that is no longer probable are recognized immediately in Net gains (losses).
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash on hand, amounts due from banks and other highly liquid investments, such as money market instruments and debt instruments with maturities of three months or less at the time of purchase. Cash and cash equivalents are stated at fair value.
Deferred Policy Acquisition Costs and Value of Business Acquired	Deferred Policy Acquisition Costs and Value of Business Acquired DAC represents policy acquisition costs that have been capitalized and are subject to amortization. Capitalized costs are incremental, direct costs of contract acquisition and certain other costs related directly to successful acquisition activities. Such costs consist principally of commissions, underwriting, sales and contract issuance and processing expenses directly related to the successful acquisition of new and renewal business. Indirect or unsuccessful acquisition costs, maintenance, product development and overhead expenses are charged to expense as incurred. VOBA represents the outstanding value of in-force business acquired and is subject to amortization. The value is based on the present value of estimated net cash flows embedded in the insurance contracts at the time of the acquisition and increased for subsequent deferrable expenses on purchased policies. DAC/VOBA amortization is recorded in Net amortization of Deferred policy acquisition costs and Value of business acquired in the Consolidated Statements of Operations. Amortization Methodologies The Company amortizes DAC/VOBA related to deferred annuity contracts on a constant level basis over the expected term of the related contracts. Contracts are grouped for amortization purposes by market type and issue year cohort using assumptions on a basis consistent with those used in estimating the associated liability or other related balance, where applicable. The principal assumption deemed critical to the DAC/VOBA amortization is the estimated contract term, which incorporates mortality and persistency, and represents management’s best estimate of future outcome. The Company periodically reviews this assumption against actual experience and, based on additional information that becomes available, updates the assumption. Changes in contract term estimates are reflected prospectively in amortization expense as of the beginning of the reporting period in which the change is made. VOBA is subject to recoverability testing; DAC is not. The Company performs testing to assess the recoverability of VOBA on an annual basis, or more frequently if circumstances indicate a potential loss recognition issue exists. If VOBA is not deemed recoverable, charges will be applied against the VOBA balance before an additional reserve is established. Internal Replacements Contract owners may periodically exchange one contract for another, or make modifications to an existing contract. These transactions are identified as internal replacements. Internal replacements that are determined to result in substantially unchanged contracts are accounted for as continuations of the replaced contracts. Any costs associated with the issuance of the new contracts are considered maintenance costs and expensed as incurred. Unamortized DAC/VOBA related to the replaced contracts continue to be deferred and amortized in connection with the new contracts. Internal replacements that are determined to result in contracts that are substantially changed are accounted for as extinguishments of the replaced contracts, and any unamortized DAC/VOBA related to the replaced contracts are written off to Net amortization of Deferred policy acquisition costs and Value of business acquired in the Consolidated Statements of Operations. Contract Costs Associated with Certain Revenue Contracts Contract cost assets represent costs incurred to obtain or fulfill contracts for non-insurance financial services that are expected to be recovered and, thus, have been capitalized and are subject to amortization. Capitalized contract costs include incremental costs of obtaining a contract and fulfillment costs that relate directly to a contract and generate or enhance resources of the Company that are used to satisfy performance obligations. Capitalized contract costs are amortized on a straight-line basis over the estimated lives of the contracts, which typically range from 5 to 15 years. Capitalized contract costs are included in Other assets on the Consolidated Balance Sheets, and costs expensed as incurred are included in Operating expenses in the Consolidated Statements of Operations. As of December 31, 2023 and 2022, contract cost assets were $99 and $100, respectively. For the years ended December 31, 2023, 2022 and 2021, amortization expenses of $21, $22 and $23, respectively, were recorded in Operating expenses in the Consolidated Statements of Operations. There was no impairment loss in relation to the contract costs capitalized.
Future Policy Benefits and Contract Owner Accounts	Future Policy Benefits and Contract Owner Account Balances Future Policy Benefits The Company establishes and carries actuarially-determined reserves that are calculated to meet its future obligations, including estimates of unpaid claims and claims that the Company believes have been incurred but have not yet been reported as of the balance sheet date. Reserves for payout contracts with life contingencies are equal to the present value of future payments. Principal assumptions used to establish liabilities for future policy benefits include interest rate, mortality, morbidity, policy lapse, contract renewal, payment of subsequent premiums or deposits by the contract owner, retirement, inflation, and benefit utilization. Other than interest rate assumptions, these assumptions are based on Company experience and periodically reviewed against industry standards. The Company reviews these assumptions at least annually and updates them if necessary. In addition to assumption updates, the Company adjusts reserves for actual experience in the period in which the experience occurs. Changes in, or deviations from, the assumptions used can significantly affect the Company's reserve levels and related results of operations. Remeasurements of the reserves as a result of assumption updates and adjustments for actual experience are recognized in Interest credited and other benefits to contract owners/policyholders in the Consolidated Statements of Operations. Interest rates used in discounting the reserves are based on an upper-medium grade (low-credit-risk) fixed-income instrument yield derived from observable market data. A 30-year forward rate is used for periods beyond the last observable market point. Reserves are remeasured quarterly to reflect changes in the discount rate, with the resulting change recorded in AOCI. Locked-in interest rates used to determine interest accretion on reserves for new contracts sold after January 1, 2021 are based on the upper-medium grade (low-credit-risk) fixed-income instrument yield applicable at the time the contract was issued. Locked-in interest accretion rates for contracts in force as of the January 1, 2021 transition date for ASU 2018-12 are based on the locked-in interest rates in effect for those contracts immediately before the transition date. Interest accretion is recorded in Interest credited and other benefits to contract owners/policyholders. Contract Owner Account Balances Contract owner account balances relate to investment-type contracts, as follows: • Account balances for funding agreements with fixed maturities are calculated using the amount deposited with the Company, less withdrawals, plus interest accrued to the ending valuation date. Interest on these contracts is accrued by a predetermined index, plus a spread or a fixed rate, established at the issue date of the contract. • Account balances for fixed annuities and payout contracts without life contingencies are equal to cumulative deposits, less charges and withdrawals, plus credited interest thereon. Credited interest rates vary by product and range up to 4.5%. Account balances for group immediate annuities without life contingent payouts are equal to the discounted value of the payment at the implied break-even rate.
Product Guarantees and Additional Reserves	Product Guarantees and Additional Reserves The Company calculates additional reserve liabilities for certain variable annuity guaranteed benefits and variable funding products. The Company periodically evaluates its estimates and adjusts the additional liability balance, with a related charge or credit to benefit expense, if actual experience or other evidence suggests that earlier assumptions should be revised. Changes in, or deviations from, the assumptions used can significantly affect the Company's reserve levels and related results of operations. Stabilizer and MCG: Guaranteed credited rates give rise to an embedded derivative in the stabilizer ("Stabilizer") products and a stand-alone derivative for managed custody guarantee products ("MCG"). These derivatives are measured at estimated fair value and recorded in Future policy benefits and contract owner account balances. Changes in estimated fair value, that are not related to attributed fees collected or payments made, are reported in Net gains (losses) in the Consolidated Statements of Operations. The estimated fair value of the Stabilizer embedded derivative and MCG stand-alone derivative is determined based on the present value of projected future claims, minus the present value of future guaranteed premiums. At inception of the contract, the Company projects a guaranteed premium to be equal to the present value of the projected future claims. The income associated with the contracts is projected using actuarial and capital market assumptions, including benefits and related contract charges, over the anticipated life of the related contracts. The cash flow estimates are projected under multiple capital market scenarios using observable risk-free rates and other best estimate assumptions. The liabilities for the Stabilizer embedded derivative and the MCG stand-alone derivative include a risk margin to capture uncertainties related to policyholder behavior assumptions. The margin represents additional compensation a market participant would require to assume these risks. The discount rate used to determine the fair value of the liabilities for the Stabilizer embedded derivative and the MCG stand-alone derivative includes an adjustment to reflect the risk that these obligations will not be fulfilled ("nonperformance risk").
Separate Accounts	Separate Accounts Separate account assets and liabilities generally represent funds maintained to meet specific investment objectives of contract owners or participants who bear the investment risk, subject, in limited cases, to minimum guaranteed rates. Investment income and investment gains and losses generally accrue directly to such contract owners. The assets of each account are legally segregated and are not subject to claims that arise out of any other business of the Company or its affiliates. Separate account assets supporting variable options under variable annuity contracts are invested, as designated by the contract owner or participant under a contract, in shares of mutual funds that are managed by the Company, or its affiliates, or in other selected mutual funds not managed by the Company, or its affiliates. The Company reports separately, as assets and liabilities, investments held in the separate accounts and liabilities of separate accounts if: • Such separate accounts are legally recognized; • Assets supporting the contract liabilities are legally insulated from the Company's general account liabilities; • Investments are directed by the contract owner or participant; and • All investment performance, net of contract fees and assessments, is passed through to the contract owner. The Company reports separate account assets that meet the above criteria at fair value on the Consolidated Balance Sheets based on the fair value of the underlying investments. The underlying investments include mutual funds, short term investments, cash and fixed maturities. Separate account liabilities equal separate account assets. Investment income and net realized and unrealized capital gains (losses) of the separate accounts, however, are not reflected in the Consolidated Statements of Operations, and the Consolidated Statements of Cash Flows do not reflect investment activity of the separate accounts.
Repurchase Agreements	Repurchase Agreements The Company engages in dollar repurchase agreements with MBS ("dollar rolls") and repurchase agreements with other collateral types to increase its return on investments and improve liquidity. Such arrangements meet the requirements to be accounted for as financing arrangements. The Company enters into dollar roll transactions by selling existing MBS and concurrently entering into an agreement to repurchase similar securities within a short time frame at a lower price. Under repurchase agreements, the Company borrows cash from a counterparty at an agreed upon interest rate for an agreed upon time frame and pledges collateral in the form of securities. At the end of the agreement, the counterparty returns the collateral to the Company, and the Company, in turn, repays the loan amount along with the additional agreed upon interest. The Company's policy requires that at all times during the term of the dollar roll and repurchase agreements that cash or other collateral types obtained is sufficient to allow the Company to fund substantially all of the cost of purchasing replacement assets. Cash received is generally invested in short-term investments, which are included in Short-term investments under securities loan agreements, including collateral delivered, with the offsetting obligation to repay the loan included within Payables under securities loan agreements, including collateral held, on the Consolidated Balance Sheets. The carrying value of the securities pledged in dollar rolls and repurchase agreement transactions is included in Securities pledged on the Consolidated Balance Sheets.
Recognition of Insurance Revenue and Related Benefits	Recognition of Revenue Insurance Revenue and Related Benefits Premiums related to payouts contracts with life contingencies are recognized in Premiums in the Consolidated Statements of Operations when due from the contract owner. When premiums are due over a significantly shorter period than the period over which benefits are provided, any gross premium in excess of the net premium (i.e., the portion of the gross premium required to provide for all expected future benefits and expenses) is deferred and recognized into revenue in a constant relationship to insurance in force. Benefits are recorded in Interest credited and other benefits to contract owners/policyholders in the Consolidated Statements of Operations when incurred. Amounts received as payment for investment-type, fixed annuities, and payout contracts without life contingencies are reported as deposits to contract owner account balances. Revenues from these contracts consist primarily of fees assessed against the contract owner account balance for mortality and policy administration charges and are reported in Fee income in the Consolidated Statements of Operations. Surrender charges are reported in Other revenue in the Consolidated Statements of Operations. In addition, the Company earns investment income from the investment of contract deposits in the Company's general account portfolio, which is reported in Net investment income in the Consolidated Statements of Operations. Benefits and expenses for these products include claims in excess of related account balances, expenses of contract administration and interest credited to contract owner account balances. Revenue from Contracts with Customers Revenue for various financial services is measured based on consideration specified in a contract with a customer and is recognized when the Company has satisfied a performance obligation, unless the transaction price includes variable consideration that is constrained; in such case, we recognize revenue when the uncertainty associated with the constrained amount is subsequently resolved. For advisory and recordkeeping and administration ("R&A") services, the Company recognizes revenue as services are provided, generally over time. The Company provides distribution services at a point in time and recognizes the related revenue as consideration is received. Revenue from shareholder servicing is recognized as services are provided over time. Contract terms are typically less than one year, and consideration is variable. Revenue for financial service is recorded in Fee income and Other revenue in the Consolidated Statements of Operations. For a description of principal activities from which the Company generates revenue, see the Business section above for further information. See the Revenue from Contracts with Customers Note in these Consolidated Financial Statements for revenue disaggregated by type of service.
Income Tax	Income Taxes The Company uses certain assumptions and estimates in determining (a) the income taxes payable or refundable to/from Voya Financial, Inc. for the current year, (b) the provision for income taxes and (c) the deferred income tax assets and liabilities. The provision for income taxes is based on income and expense reported in the financial statements after adjustments for permanent differences between our financial statements and consolidated federal income tax return. Permanent differences include the dividends received deduction. As a result of permanent differences, the effective tax rate reflected in the financial statements may be different than the actual rate in the income tax return. Current income tax receivable or payable is recognized within Other assets or Other liabilities, respectively, in the Consolidated Balance Sheets. Temporary differences between the Company's financial statements and income tax return create deferred tax assets and liabilities. Deferred tax assets represent the tax benefit of future deductible temporary differences, net operating loss carryforwards and tax credit carryforwards. The Company's deferred tax assets and liabilities are measured at the balance sheet date using enacted tax rates expected to apply to taxable income in the years the temporary differences are expected to reverse. The Company evaluates and tests the recoverability of its deferred tax assets. Deferred tax assets are reduced by a valuation allowance if, based on the weight of evidence, it is more likely than not that some portion, or all, of the deferred tax assets will not be realized. Considerable judgment and the use of estimates are required in determining whether a valuation allowance is necessary and, if so, the amount of such valuation allowance. In evaluating the need for a valuation allowance, the Company considers many factors, including the nature and character of the deferred tax assets and liabilities, the amount and character of book income or losses in recent years, projected future taxable income and future reversals of temporary differences, tax planning strategies we would employ to avoid a tax benefit from expiring unused, and the length of time carryforwards can be utilized. The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not to be sustained under examination by the applicable taxing authority. The Company also considers positions that have been reviewed and agreed to as part of an examination by the applicable taxing authority. For items that meet the more-likely-than-not recognition threshold, the Company measures the tax position as the largest amount of benefit that is more than 50% likely to be realized upon ultimate resolution with the applicable tax authority that has full knowledge of all relevant information.
Reinsurance	Reinsurance The Company utilizes reinsurance agreements in most aspects of its insurance business to reduce its exposure to large losses. Such reinsurance permits recovery of a portion of losses from reinsurers, although it does not discharge the primary liability of the Company as direct insurer of the risks reinsured. For each of its reinsurance agreements, the Company determines whether the agreement provides indemnification against loss or liability relating to insurance risk. The Company reviews contractual features, particularly those that may limit the amount of insurance risk to which the reinsurer is subject or features that delay the timely reimbursement of claims. The assumptions used to account for long-duration reinsurance agreements are consistent with those used for the underlying contracts with the exception of the interest accretion rate on reinsurance recoverable assets associated with in-force business reinsured. Ceded Future policy benefits and contract owner account balances are reported gross on the Consolidated Balance Sheets. For reinsurance of long-duration contracts that transfer significant insurance risk, the difference, if any, between the amounts paid and benefits received related to the underlying contracts is included in the expected net cost of reinsurance, which is recorded in Premiums receivable and reinsurance recoverable or Other liabilities, as appropriate, on the Consolidated Balance Sheets. If the Company determines that a reinsurance agreement does not expose the reinsurer to a reasonable possibility of a significant loss from insurance risk, the Company records the agreement using the deposit method of accounting. Deposits received are included in Other liabilities, and deposits made are included in Other assets on the Consolidated Balance Sheets. As amounts are paid or received, consistent with the underlying contracts, the deposit assets or liabilities are adjusted. Accounting for reinsurance requires use of assumptions and estimates, particularly related to the future performance of the underlying business and the potential impact of counterparty credit risks. The Company reviews assumptions used to establish assets and liabilities relating to ceded and assumed reinsurance at least annually and updates them if necessary. In addition to the assumption updates, the Company adjusts these assets or liabilities for actual experience in the period in which the experience occurs. The Company also evaluates the financial strength of potential reinsurers and continually monitors the financial condition of reinsurers. Reinsurance recoverable and deposit asset balances are reported net of the allowance for credit losses in the Company’s Consolidated Balance Sheets. Management estimates the credit loss allowance balance using a factor-based method of probability of default and loss given default which incorporates relevant available information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. Included in the factor-based method are the consideration of capital market factors, counterparty financial information and ratings, and reinsurance agreement-specific risk characteristics such as collateral type, collateral size, and covenant strength. The allowance for credit losses is a valuation account that is deducted from the reinsurance recoverable balance to present the net amount expected to be collected on the reinsurance recoverable. The change in the allowance for credit losses is recorded in Policyholder benefits in the Consolidated Statements of Operations. Current reinsurance recoverable balances deemed probable of recovery and payable balances under reinsurance agreements are included in Premiums receivable and reinsurance recoverable and Other liabilities, respectively. Such assets and liabilities relating to reinsurance agreements with the same reinsurer are recorded net on the Consolidated Balance Sheets if a right of offset exists within the reinsurance agreement. Premiums, Fee income and Interest credited and other benefits to contract owners/policyholders are reported net of reinsurance ceded. The Company currently has a significant concentration of ceded reinsurance with a subsidiary of Lincoln National Corporation ("Lincoln") and Security Life of Denver ("SLD") arising from the disposition of its individual life and annuity business.
Employee Benefits Plans	Employee Benefits Plans The Company, in conjunction with Voya Services Company, sponsors non-qualified defined benefit pension plans covering eligible employees, sales representatives, and other individuals. A defined benefit plan is a pension plan that defines an amount of pension benefit that an employee will receive upon retirement, usually dependent on one or more factors such as age, years of service and compensation. The liability recognized in respect of non-qualified defined benefit pension plans is the present value of the projected pension benefit obligation ("PBO") at the balance sheet date, together with adjustments for unrecognized past service costs. This liability is included in Other liabilities on the Consolidated Balance Sheets. The PBO is defined as the actuarially calculated present value of vested and non-vested pension benefits accrued based on future salary levels. The Company recognizes the funded status of the PBO for pension plans on the Consolidated Balance Sheets. Net periodic benefit cost for the non-qualified defined benefit pension plans is determined using management estimates and actuarial assumptions to derive service cost and interest cost for a particular year and is included in Operating expenses in the Consolidated Statements of Operations. The obligations and expenses associated with these plans require use of assumptions, such as discount rate and rate of future compensation increases and healthcare cost trend rates, as well as assumptions regarding participant demographics, such as age of retirement, withdrawal rates, and mortality. Management determines these assumptions based on a variety of factors, such as currently available market and industry data and expected benefit payout streams. Actual results could vary significantly from assumptions based on changes, such as economic and market conditions, demographics of participants in the plans, and amendments to benefits provided under the plans. These differences may have a significant effect on the Company's Consolidated Financial Statements and liquidity. Actuarial gains (losses) are immediately recognized in Operating expenses in the Consolidated Statements of Operations.
Contingencies	Contingencies A loss contingency is an existing condition, situation or set of circumstances involving uncertainty as to possible loss that will ultimately be resolved when one or more future events occur or fail to occur. Examples of loss contingencies include pending or threatened adverse litigation, threat of expropriation of assets and actual or possible claims and assessments. Amounts related to loss contingencies are accrued and recorded in Other liabilities on the Consolidated Balance Sheets if it is probable that a loss has been incurred and the amount can be reasonably estimated, based on the Company's best estimate of the ultimate outcome.
Adoption of New Pronouncements and Future Adoption of Accounting Pronouncements	Adoption of New Pronouncements Long-Duration Contracts The following section provides a description of the Company's adoption of ASU 2018-12 issued by the Financial Accounting Standards Board ("FASB") and the impact of the adoption on the Company's financial statements: This standard, issued in August 2018, changes the measurement and disclosures of insurance liabilities and DAC for long-duration contracts issued by insurers. In addition to expanded disclosures, the standard’s requirements include: • Annual review and, if necessary, update of cash flow assumptions used to measure the liability for future policy benefits for nonparticipating traditional and limited payment insurance contracts, measured on a retrospective catch-up basis and recognized in the period the update is made. The rate used is required to be updated quarterly, with related changes in the liability recorded in AOCI. • Fair value measurement of contract guarantee features qualifying as Market Risk Benefits ("MRB"), with changes in fair value recognized in the Statement of Operations. Changes in the instrument-specific credit risk will be recorded in AOCI. • Amortization of DAC on a constant level basis over the expected term of the contracts, without reference to revenue or profitability. An accounting election may be made to apply the DAC requirements to VOBA. The Company adopted ASU 2018-12 on January 1, 2023, on a modified retrospective basis for the liability for future policy benefits and DAC and on a full retrospective basis for MRBs. The January 1, 2021 transition impact increased Total shareholder’s equity. This increase was primarily driven by the removal of DAC/VOBA and premium deficiency reserve adjustment balances, and partially offset by the impact of remeasurement of future policy benefits and reinsurance recoverable using the discount rate at January 1, 2021. Total shareholder’s equity was also impacted by the establishment of MRB liabilities related to guaranteed minimum benefits on certain deferred annuity contracts. Disclosures and post-transition comparative information have been restated to conform to the requirements of ASU 2018-12. The following tables provide additional information related to the transition adjustments: DAC VOBA Wealth Solutions Deferred and Individual Annuities Balance, December 31, 2020 $ 129 $ 40 Adjustment for removal of related balances in AOCI 439 386 Balance, January 1, 2021 $ 568 $ 426 The following table presents information on transition adjustments, net of tax, related to the adoption of ASU 2018-12 for retained earnings and AOCI to arrive at the opening balances as of January 1, 2021: Total Shareholder's equity December 31, 2020 $ 4,897 AOCI Reversal of AOCI adjustments 1,018 Effect of remeasurement of liability at current discount rate (339) Total AOCI adjustments $ 679 Retained Earnings Establishment of MRBs $ (61) Other adjustments 3 Total Retained earnings $ (58) Total adjustment for the adoption of ASU 2018-12 $ 621 Total Shareholder's equity January 1, 2021 $ 5,518 The following table provides a description of the Company's adoption of new ASUs issued by the FASB and the impact of the adoption on the Company's financial statements: Standard Description of Requirements Effective Date and Method of Adoption Effect on the Financial Statements or Other Significant Matters ASU 2022-02, Troubled Debt Restructurings ("TDRs") and Vintage Disclosures This standard, issued in March 2022, eliminates the accounting guidance on troubled debt restructurings for creditors, requires enhanced disclosures for creditors about loan modifications when a borrower is experiencing financial difficulty, and requires public business entities to include current-period gross write-offs in the vintage disclosure tables. January 1, 2023 on a prospective basis. Adoption of the ASU did not have an impact on the Company's financial condition, results of operations, or cash flows. Required disclosure changes have been included in the Investments Note to these Consolidated Financial Statements. ASU 2020-04, Reference Rate Reform This standard, issued in March 2020, provides temporary optional expedients and exceptions for applying U.S. GAAP principles to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments were effective as of March 12, 2020, the issuance date of the ASU. An entity may elect to apply the amendments prospectively through December 31, 2024. Effective December 31, 2023, the Company completed its implementation of ASU 2020-04 and applied the expedient provided for qualifying contract modifications. Adoption of the guidance did not have a material impact on the Company’s financial condition, results of operations, or cash flows. Future Adoption of Accounting Pronouncements The following table provides a description of future adoptions of new accounting standards that may have an impact on the Company's financial statements when adopted: Standard Description of Requirements Effective Date and Transition Provisions Effect on the Financial Statements or Other Significant Matters ASU 2023-09, Improvements to Income Tax Disclosures This standard, issued in December 2023, requires the following disclosures: • A tabular rate reconciliation of (1) reported income tax expense/benefit from continuing operations, to (2) the product of the income/loss from continuing operations before income taxes and the statutory federal income tax rate, using specific categories, as well as disclosure of certain reconciling items based on a 5% threshold. • Year-to-date net income taxes paid, disaggregated by federal, state, and foreign, as well as disaggregated information on net income taxes paid to an individual jurisdiction based on a 5% threshold. The amendments are effective for annual periods beginning after December 15, 2024, and should be applied prospectively, with retrospective application permitted. The Company is currently in the process of determining the impact of adoption of the provisions of ASU 2023-09. ASU 2023-07, Improvements to Reportable Segment Disclosure This standard, issued in November 2023, requires all current annual disclosures about profit/loss and assets to be reported in interim periods, as well as enhanced disclosures about significant segment expenses, including: • Significant expenses regularly provided to the chief operating decision maker (“CODM”) and included within each reported measure of profit/loss • Amount and composition of “other segment items” (difference between revenue less significant expenses disclosed, and each reported measure of segment profit/loss) • May report additional measures of profit/loss if the CODM uses more than one measure; however, at least one should be the measure that is most consistent with the principles used in measuring corresponding financial statement amounts • Title and position of the CODM and how the CODM uses the reported measure(s) in assessing segment performance and resource allocation An entity with a single reportable segment must provide all the disclosures required by the amendments in ASU 2023-07 and all existing segment disclosures in ASC 280. The amendments are effective for fiscal years beginning after December 15, 2023, and interim periods beginning after December 15, 2024, and are required to be applied retrospectively. Restated prior period disclosures should be based on the significant segment expense categories disclosed in the period of adoption The Company is currently in the process of determining the impact of adoption of the provisions of ASU 2023-07. ASU 2022-03, Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions This standard, issued in June 2022, clarifies that contractual restrictions on equity security sales are not considered part of the security unit of account and, therefore, are not considered in measuring fair value. In addition, the restrictions cannot be recognized and measured as separate units of account. Disclosures on such restrictions are also required. The amendments are effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years, and are required to be applied prospectively, with any adjustments from the adoption recognized in earnings and disclosed. The Company is currently in the process of determining the impact of adoption of the provisions of ASU 2022-03; however, the Company does not expect the adoption to have a material impact on the Company's financial condition and results of operations.

Fair Value Disclosures [Abstract]
Fair Value Measurement	Fair Value Measurement The Company measures the fair value of its financial assets and liabilities based on assumptions used by market participants in pricing the asset or liability, which may include inherent risk, restrictions on the sale or use of an asset, or nonperformance risk, including the Company's own credit risk. The estimate of fair value is the price that would be received to sell an asset or transfer a liability ("exit price") in an orderly transaction between market participants in the principal market, or the most advantageous market in the absence of a principal market, for that asset or liability. The Company uses a number of valuation sources to determine the fair values of its financial assets and liabilities, including quoted market prices, third-party commercial pricing services, third-party brokers, industry-standard, vendor-provided software that models the value based on market observable inputs, and other internal modeling techniques based on projected cash flows.
