Nature of Operations, Basis of Presentation and Summary of Significant Accounting Policies [Abstract]
Nature of Operations, Basis of Presentation and Summary of Significant Accounting Policies	1. Na ture of Operations, Basis of Presentation and Summary of Significant Accounting Policies Nature of Operations The Lincoln National Life Insurance Company (“LNL” or the “Company,” which also may be referred to as “we,” “our” or “us”), a wholly-owned subsidiary of Lincoln National Corporation (“LNC” or the “Parent Company”), is domiciled in the state of Indiana. We own 100% of the outstanding common stock of one insurance company subsidiary, Lincoln Life & Annuity Company of New York (“LLANY”). We also own several non-insurance companies, including Lincoln Financial Distributors, our wholesale distributor, and Lincoln Financial Advisors Corporation, part of LNC’s retail distributor, Lincoln Financial Network. LNL is licensed and sells its products throughout the U.S. and several U.S. territories. Through our business segments, we sell a wide range of wealth protection, accumulation, group protection and retirement income products and solutions. These products primarily include universal life insurance (“UL”), variable universal life insurance (“VUL”), linked-benefit UL and VUL, indexed universal life insurance (“IUL”), term life insurance, fixed and indexed annuities, variable annuities, group life, disability and dental and employer-sponsored retirement plans and services. For more information on our segments and the products and solutions we provide, see Note 15. Basis of Presentation The accompanying unaudited consolidated financial statements are prepared in accordance with United States of America generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions for the Securities and Exchange Commission (“SEC”) Quarterly Report on Form 10-Q, including Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. The information contained in the Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, as amended by Amendment No. 1 thereto (“2022 Form 10-K”), should be read in connection with the reading of these interim unaudited consolidated financial statements. Certain GAAP policies, which significantly affect the determination of financial condition, results of operations and cash flows, are summarized below. In the opinion of management, these statements include all normal recurring adjustments necessary for a fair presentation of the Company’s results. Operating results for the three months ended March 31, 2023, are not necessarily indicative of the results that may be expected for the full year ending December 31, 2023. All material inter-company accounts and transactions have been eliminated in consolidation. Certain amounts reported in prior periods’ consolidated financial statements have been reclassified to conform to the presentation adopted in the current period. We present disaggregated disclosures in the Notes below for long-duration insurance balances, applying the level of aggregation by reportable segment as follows: Reportable Segment Level of Aggregation Life Insurance Traditional Life UL and Other Annuities Variable Annuities Fixed Annuities Payout Annuities Group Protection Group Protection Retirement Plan Services Retirement Plan Services The fixed annuities level of aggregation represents deferred fixed annuities. We have excluded amounts reported in Other Operations from our disaggregated disclosures that are attributable to the indemnity reinsurance agreements with Protective Life Insurance Company (“Protective”) and Swiss Re Life & Health America, Inc (“Swiss Re”) as these contracts are fully reinsured, run-off institutional pension business in the form of group annuity and the results of certain disability income business and not reflected in the results of the reportable segments listed above. Summary of Significant Accounting Policies Principles of Consolidation The accompanying consolidated financial statements include the accounts of LNL and all other entities in which we have a controlling financial interest and any variable interest entities (“VIEs”) in which we are the primary beneficiary. We use the equity method of accounting to recognize all of our investments in limited liability partnerships. All material inter-company accounts and transactions have been eliminated in consolidation. Our involvement with VIEs is primarily to invest in assets that allow us to gain exposure to a broadly diversified portfolio of asset classes. A VIE is an entity that does not have sufficient equity to finance its own activities without additional financial support or where investors lack certain characteristics of a controlling financial interest. We assess our contractual, ownership or other interests in a VIE to determine if our interest participates in the variability the VIE was designed to absorb and pass onto variable interest holders. We perform an ongoing qualitative assessment of our variable interests in VIEs to determine whether we have a controlling financial interest and would therefore be considered the primary beneficiary of the VIE. If we determine we are the primary beneficiary of a VIE, we consolidate the assets and liabilities of the VIE in the consolidated financial statements. Accounting Estimates and Assumptions The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions affecting the reported amounts of assets and liabilities and the disclosures of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses for the reporting period. In applying these estimates and assumptions, management makes subjective and complex judgments that frequently require assumptions about matters that are uncertain and inherently subject to change, including matters related to or impacted by the COVID-19 pandemic. Actual results could differ from these estimates and assumptions. Included among the material (or potentially material) reported amounts and disclosures that require use of estimates are: fair value of certain financial assets, derivatives, allowances for credit losses, deferred acquisition costs (“DAC”), value of business acquired (“VOBA”), DSI, goodwill and other intangibles, market risk benefits (“MRBs”), future contract benefits, DFEL, pension plans, stock-based incentive compensation, income taxes including the recoverability of our deferred tax assets, and the potential effects of resolving litigated matters. Business Combinations We use the acquisition method of accounting for all business combination transactions, and accordingly, recognize the fair values of assets acquired, liabilities assumed and any noncontrolling interests in the consolidated financial statements. The allocation of fair values may be subject to adjustment after the initial allocation for up to a one-year period as more information becomes available relative to the fair values as of the acquisition date. The consolidated financial statements include the results of operations of any acquired company since the acquisition date. Fair Value Measurement Our measurement of fair value is 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 non-performance risk, which would include our own credit risk. Our estimate of an exchange price is the price in an orderly transaction between market participants to sell the asset or transfer the liability (“exit price”) in the principal market, or the most advantageous market in the absence of a principal market, for that asset or liability, as opposed to the price that would be paid to acquire the asset or receive a liability (“entry price”). Pursuant to the Fair Value Measurements and Disclosures Topic of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification TM (“ASC”), we categorize our financial instruments carried at fair value into a three-level fair value hierarchy, based on the priority of inputs to the respective valuation technique. The three-level hierarchy for fair value measurement is defined as follows:  Level 1 – inputs to the valuation methodology are quoted prices available in active markets for identical investments as of the reporting date, except for large holdings subject to “blockage discounts” that are excluded;  Level 2 – inputs to the valuation methodology are other than quoted prices in active markets, which are either directly or indirectly observable as of the reporting date, and fair value can be determined through the use of models or other valuation methodologies; and  Level 3 – inputs to the valuation methodology are unobservable inputs in situations where there is little or no market activity for the asset or liability, and we make estimates and assumptions related to the pricing of the asset or liability, including assumptions regarding risk. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the investment. When a determination is made to classify an asset or liability within Level 3 of the fair value hierarchy, the determination is based upon the significance of the unobservable inputs to the overall fair value measurement. Because certain securities trade in less liquid or illiquid markets with limited or no pricing information, the determination of fair value for these securities is inherently more difficult. However, Level 3 fair value investments may include, in addition to the unobservable or Level 3 inputs, observable components, which are components that are actively quoted or can be validated to market-based sources. Fixed Maturity Available-For-Sale Securities – Fair Valuation Methodologies and Associated Inputs Securities classified as available-for-sale (“AFS”) consist of fixed maturity securities and are stated at fair value with unrealized gains and losses included within accumulated other comprehensive income (loss) (“AOCI”). We measure the fair value of our securities classified as fixed maturity AFS based on assumptions used by market participants in pricing the security. The most appropriate valuation methodology is selected based on the specific characteristics of the fixed maturity security, and we consistently apply the valuation methodology to measure the security’s fair value. Our fair value measurement is based on a market approach that utilizes prices and other relevant information generated by market transactions involving identical or comparable securities. Sources of inputs to the market approach primarily include third-party pricing services, independent broker quotations or pricing matrices. We do not adjust prices received from third parties; however, we do analyze the third-party pricing services’ valuation methodologies and related inputs and perform additional evaluation to determine the appropriate level within the fair value hierarchy. The observable and unobservable inputs to our valuation methodologies are based on a set of standard inputs that we generally use to evaluate all of our fixed maturity AFS securities. Observable inputs include benchmark yields, reported trades, broker-dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers and reference data. In addition, market indicators, industry and economic events are monitored, and further market data is acquired if certain triggers are met. For certain security types, additional inputs may be used, or some of the inputs described above may not be applicable. For private placement securities, we use pricing matrices that utilize observable pricing inputs of similar public securities and Treasury yields as inputs to the fair value measurement. Depending on the type of security or the daily market activity, standard inputs may be prioritized differently or may not be available for all fixed maturity AFS securities on any given day. For broker-quoted only securities, non-binding quotes from market makers or broker-dealers are obtained from sources recognized as market participants. For securities trading in less liquid or illiquid markets with limited or no pricing information, we use unobservable inputs to measure fair value. The following summarizes our fair valuation methodologies and associated inputs, which are particular to the specified security type and are in addition to the defined standard inputs to our valuation methodologies for all of our fixed maturity AFS securities discussed above:  Corporate bonds and U.S. government bonds – We also use Trade Reporting and Compliance Engine TM reported tables for our corporate bonds and vendor trading platform data for our U.S. government bonds.  Mortgage and asset-backed securities (“ABS”) – We also utilize additional inputs, which include new issues data, monthly payment information and monthly collateral performance, including prepayments, severity, delinquencies, step-down features and over collateralization features for each of our mortgage-backed securities (“MBS”), which include collateralized mortgage obligations and mortgage pass through securities backed by residential mortgages (“RMBS”), commercial mortgage-backed securities (“CMBS”) and collateralized loan obligations (“CLOs”).  State and municipal bonds – We also use additional inputs that include information from the Municipal Securities Rule Making Board, as well as material event notices, new issue data, issuer financial statements and Municipal Market Data benchmark yields for our state and municipal bonds.  Hybrid and redeemable preferred securities – We also utilize additional inputs of exchange prices (underlying and common stock of the same issuer) for our hybrid and redeemable preferred securities. In order to validate the pricing information and broker-dealer quotes, we employ, where possible, procedures that include comparisons with similar observable positions, comparisons with subsequent sales and observations of general market movements for those security classes. We have policies and procedures in place to review the process that is utilized by our third-party pricing service and the output that is provided to us by the pricing service. On a periodic basis, we test the pricing for a sample of securities to evaluate the inputs and assumptions used by the pricing service, and we perform a comparison of the pricing service output to an alternative pricing source. We also evaluate prices provided by our primary pricing service to ensure that they are not stale or unreasonable by reviewing the prices for unusual changes from period to period based on certain parameters or for lack of change from one period to the next. Fixed Maturity AFS Securities – Evaluation for Recovery of Amortized Cost We regularly review our fixed maturity AFS securities (also referred to as “debt securities”) for declines in fair value that we determine to be impairment-related, including those attributable to credit risk factors that may require a credit loss allowance. For our debt securities, we generally consider the following to determine whether our debt securities with unrealized losses are credit impaired:  The estimated range and average period until recovery;  The estimated range and average holding period to maturity;  Remaining payment terms of the security;  Current delinquencies and nonperforming assets of underlying collateral;  Expected future default rates;  Collateral value by vintage, geographic region, industry concentration or property type;  Subordination levels or other credit enhancements as of the balance sheet date as compared to origination; and  Contractual and regulatory cash obligations. For a debt security, if we intend to sell a security, or it is more likely than not we will be required to sell a debt security before recovery of its amortized cost basis and the fair value of the debt security is below amortized cost, we conclude that an impairment has occurred and the amortized cost is written down to current fair value, with a corresponding charge to realized gain (loss) on the Consolidated Statements of Comprehensive Income (Loss). If we do not intend to sell a debt security, or it is not more likely than not we will be required to sell a debt security before recovery of its amortized cost basis but the present value of the cash flows expected to be collected is less than the amortized cost of the debt security (referred to as the credit loss), we conclude that an impairment has occurred, and a credit loss allowance is recorded, with a corresponding charge to realized gain (loss) on the Consolidated Statements of Comprehensive Income (Loss). The remainder of the decline to fair value related to factors other than credit loss is recorded in other comprehensive income (“OCI”) to unrealized losses on fixed maturity AFS securities on the Consolidated Statements of Stockholder’s Equity, as this amount is considered a noncredit impairment. When assessing our intent to sell a debt security, or if it is more likely than not we will be required to sell a debt security before recovery of its cost basis, we evaluate facts and circumstances such as, but not limited to, decisions to reposition our security portfolio, sales of securities to meet cash flow needs and sales of securities to capitalize on favorable pricing. Management considers the following as part of the evaluation:  The current economic environment and market conditions;  Our business strategy and current business plans;  The nature and type of security, including expected maturities and exposure to general credit, liquidity, market and interest rate risk;  Our analysis of data from financial models and other internal and industry sources to evaluate the current effectiveness of our hedging and overall risk management strategies;  The current and expected timing of contractual maturities of our assets and liabilities, expectations of prepayments on investments and expectations for surrenders and withdrawals of life insurance policies and annuity contracts;  The capital risk limits approved by management; and  Our current financial condition and liquidity demands. In order to determine the amount of the credit loss for a debt security, we calculate the recovery value by performing a discounted cash flow analysis based on the current cash flows and future cash flows we expect to recover. The discount rate is the effective interest rate implicit in the underlying debt security. The effective interest rate is the original yield, or the coupon if the debt security was previously impaired. See the discussion below for additional information on the methodology and significant inputs, by security type, that we use to determine the amount of a credit loss. To determine the recovery period of a debt security, we consider the facts and circumstances surrounding the underlying issuer including, but not limited to, the following:  Historical and implied volatility of the security;  The extent to which the fair value has been less than amortized cost;  Adverse conditions specifically related to the security or to specific conditions in an industry or geographic area;  Failure, if any, of the issuer of the security to make scheduled payments; and  Recoveries or additional declines in fair value subsequent to the balance sheet date. In periods subsequent to the recognition of a credit loss impairment through a credit loss allowance, we continue to reassess the expected cash flows of the debt security at each subsequent measurement date as necessary. If the measurement of credit loss changes, we recognize a provision for (or reversal of) credit loss expense through realized gain (loss) on the Consolidated Statements of Comprehensive Income (Loss), limited by the amount that amortized cost exceeds fair value. Losses are charged against the allowance for credit losses when management believes the uncollectibility of a debt security is confirmed or when either of the criteria regarding intent or requirement to sell is met. Accrued interest on debt securities is written-off when deemed uncollectible. To determine the recovery value of a corporate bond or CLO, we perform additional analysis related to the underlying issuer including, but not limited to, the following:  Fundamentals of the issuer to determine what we would recover if they were to file bankruptcy versus the price at which the market is trading;  Fundamentals of the industry in which the issuer operates;  Earnings multiples for the given industry or sector of an industry that the underlying issuer operates within, divided by the outstanding debt to determine an expected recovery value of the security in the case of a liquidation;  Expected cash flows of the issuer (e.g., whether the issuer has cash flows in excess of what is required to fund its operations);  Expectations regarding defaults and recovery rates;  Changes to the rating of the security by a rating agency; and  Additional market information (e.g., if there has been a replacement of the corporate debt security). Each quarter, we review the cash flows for the MBS portfolio, including current credit enhancements and trends in the underlying collateral performance to determine whether or not they are sufficient to provide for the recovery of our amortized cost. To determine recovery value of a MBS, we perform additional analysis related to the underlying issuer including, but not limited to, the following:  Discounted cash flow analysis based on the current cash flows and future cash flows we expect to recover;  Level of borrower creditworthiness of the home equity loans or residential mortgages that back an RMBS or commercial mortgages that back a CMBS;  Susceptibility to fair value fluctuations for changes in the interest rate environment;  Susceptibility to reinvestment risks, in cases where market yields are lower than the securities’ book yield earned;  Susceptibility to reinvestment risks, in cases where market yields are higher than the book yields earned on a security;  Expectations of sale of such a security where market yields are higher than the book yields earned on a security; and  Susceptibility to variability of prepayments. When evaluating MBS and mortgage-related ABS, we consider a number of pool-specific factors as well as market level factors when determining whether or not the impairment on the security requires a credit loss allowance. The most important factor is the performance of the underlying collateral in the security and the trends of that performance in the prior periods. We use this information about the collateral to forecast the timing and rate of mortgage loan defaults, including making projections for loans that are already delinquent and for those loans that are currently performing but may become delinquent in the future. Other factors used in this analysis include the credit characteristics of borrowers, geographic distribution of underlying loans and timing of liquidations by state. Once default rates and timing assumptions are determined, we then make assumptions regarding the severity of a default if it were to occur. Factors that impact the severity assumption include expectations for future home price appreciation or depreciation, loan size, first lien versus second lien, existence of loan level private mortgage insurance, type of occupancy and geographic distribution of loans. Once default and severity assumptions are determined for the security in question, cash flows for the underlying collateral are projected including expected defaults and prepayments. These cash flows on the collateral are then translated to cash flows on our tranche based on the cash flow waterfall of the entire capital security structure. If this analysis indicates the entire principal on a particular security will not be returned, the security is reviewed for a credit loss by comparing the expected cash flows to amortized cost. To the extent that the security has already been impaired through a credit loss allowance or was purchased at a discount, such that the amortized cost of the security is less than or equal to the present value of cash flows expected to be collected, no credit loss allowance is required. Otherwise, if the amortized cost of the security is greater than the present value of the cash flows expected to be collected, and the security was not purchased at a discount greater than the expected principal loss, then an impairment through a credit loss allowance is recognized. We further monitor the cash flows of all of our debt securities backed by mortgages on an ongoing basis. We also perform detailed analysis on all of our subprime, Alt-A, non-agency residential MBS and on a significant percentage of our debt securities backed by pools of commercial mortgages. The detailed analysis includes revising projected cash flows by updating the cash flows for actual cash received and applying assumptions with respect to expected defaults, foreclosures and recoveries in the future. These revised projected cash flows are then compared to the amount of credit enhancement (subordination) in the structure to determine whether the amortized cost of the security is recoverable. If it is not recoverable, we record an impairment through a credit loss allowance for the security. Trading Securities Trading securities consist of fixed maturity securities in designated portfolios, some of which support modified coinsurance and coinsurance with funds withheld reinsurance agreements. Investment results for the portfolios that support modified coinsurance and coinsurance with funds withheld reinsurance agreements, including gains and losses from sales, are passed directly to the reinsurers pursuant to contractual terms of the reinsurance agreements. Trading securities are carried at fair value, and changes in fair value and changes in the fair value of embedded derivative liabilities associated with the underlying reinsurance agreements are recorded in realized gain (loss) on the Consolidated Statements of Comprehensive Income (Loss) as they occur. Equity Securities Equity securities are carried at fair value, and changes in fair value are recorded in realized gain (loss) on the Consolidated Statements of Comprehensive Income (Loss) as they occur. Equity securities consist primarily of common stock of publicly-traded companies, privately placed securities and mutual fund shares. We measure the fair value of our equity securities based on assumptions used by market participants in pricing the security. The most appropriate valuation methodology is selected based on the specific characteristics of the equity security. Fair values of publicly-traded equity securities are determined using quoted prices in active markets for identical or comparable securities. When quoted prices are not available, we use valuation methodologies most appropriate for the specific asset. Fair values for private placement securities are determined using discounted cash flow, earnings multiple and other valuation models. The fair values of mutual fund shares that transact regularly are based on transaction prices of identical fund shares. Mortgage Loans on Real Estate Mortgage loans on real estate consist of commercial and residential mortgage loans and are generally carried at unpaid principal balances adjusted for amortization of premiums and accretion of discounts and are net of allowance for credit losses. We carry certain commercial mortgage loans associated with modified coinsurance agreements at fair value where the fair value option has been elected. Interest income is accrued on the principal balance of the loan based on the loan’s contractual interest rate. Premiums and discounts are amortized using the effective yield method over the life of the loan. Interest income and amortization of premiums and discounts are reported in net investment income on the Consolidated Statements of Comprehensive Income (Loss) along with mortgage loan fees, which are recorded as they are incurred. Our policy for commercial mortgage loans is to report loans that are 60 or more days past due, which equates to two or more payments missed, as delinquent. Our policy for residential mortgage loans is to report loans that are 90 or more days past due, which equates to three or more payments missed, as delinquent. We do not accrue interest on loans 90 days past due, and any interest received on these loans is either applied to the principal or recorded in net investment income on the Consolidated Statements of Comprehensive Income (Loss) when received, depending on the assessment of the collectability of the loan. We resume accruing interest once a loan complies with all of its original terms or restructured terms. Mortgage loans deemed uncollectible are charged against the allowance for credit losses, and subsequent recoveries, if any, are likewise credited to the allowance for credit losses. Accrued interest on mortgage loans is written-off when deemed uncollectible. In connection with our recognition of an allowance for credit losses for mortgage loans on real estate, we perform a quantitative analysis using a probability of default/loss given default/exposure at default approach to estimate expected credit losses in our mortgage loan portfolio as well as unfunded commitments related to commercial mortgage loans, exclusive of certain mortgage loans held at fair value. Our model estimates expected credit losses over the contractual terms of the loans, which are the periods over which we are exposed to credit risk, adjusted for expected prepayments. Credit loss estimates are segmented by commercial mortgage loans, residential mortgage loans, and unfunded commitments related to commercial mortgage loans. The allowance for credit losses for pooled loans of similar risk (i.e., commercial and residential mortgage loans) is estimated using relevant historical credit loss information adjusted for current conditions and reasonable and supportable forecasts of future conditions. Historical credit loss experience provides the basis for the estimation of expected credit losses with adjustments for differences in current loan-specific risk characteristics, such as differences in underwriting standards, portfolio mix, delinquency level, or term lengths as well as adjustments for changes in environmental conditions, such as unemployment rates, property values, or other factors that management deems relevant. We apply probability weights to the positive, base and adverse scenarios we use. For periods beyond our reasonable and supportable forecast, we use implicit mean reversion over the remaining life of the recoverable, meaning our model will inherently revert to the baseline scenario as the baseline is representative of the historical average over a longer period of time. Loans are considered impaired when it is probable that, based upon current information and events, we will be unable to collect all amounts due under the contractual terms of the loan agreement. When we determine that a loan is impaired, a specific credit loss allowance is established for the excess carrying value of the loan over its estimated value. The loan’s estimated value is based on: the present value of expected future cash flows discounted at the loan’s effective interest rate; the loan’s observable market price; or the fair value of the loan’s collateral. Allowance for credit losses are maintained at a level we believe is adequate to absorb current expected lifetime credit losses. Our periodic evaluation of the adequacy of the allowance for credit losses is based on historical loss experience, known and inherent risks in the portfolio, adverse situations that may affect the borrower’s ability to repay (including the timing of future payments), the estimated value of the underlying collateral, composition of the loan portfolio, current economic conditions, reasonable and supportable forecasts about the future and other relevant factors. Mortgage loans on real estate are presented net of the allowance for credit losses on the Consolidated Balance Sheets. Changes in the allowance are reported in realized gain (loss) on the Consolidated Statements of Compreh

New Accounting Standards [Abstract]
New Accounting Standards	2. New Accounting Standards The following table provides a description of our adoption of new Accounting Standards Updates (“ASUs”) issued by the FASB and the impact of the adoption on the consolidated financial statements. ASUs not listed below were assessed and determined to be either not applicable or insignificant in presentation or amount. Standard Description Effective Date Effect on Financial Statements or Other Significant Matters ASU 2020-04, Reference Rate Reform (Topic 848) and related amendments The amendments in this update provide optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments provide optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions impacted by reference rate reform. If certain criteria are met, an entity will not be required to remeasure or reassess contracts impacted by reference rate reform. Additionally, changes to the critical terms of a hedging relationship affected by reference rate reform will not require entities to de-designate the relationship if certain requirements are met. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2024, with certain exceptions. The amendments are effective for contract modifications made between March 12, 2020, and December 31, 2024. March 12, 2020 through December 31, 2024 This standard may be elected and applied prospectively. We have elected practical expedients under this guidance to maintain hedge accounting for certain derivatives. This ASU has not had a material impact to our consolidated financial condition and results of operations, but we will continue to evaluate those impacts as our transition progresses. ASU 2018-12, Targeted Improvements to the Accounting for Long-Duration Contracts and related amendments See Note 3 for information about ASU 2018-12. January 1, 2023 We adopted this ASU effective January 1, 2023, with a transition date of January 1, 2021, using a modified retrospective approach, except for market risk benefits for which we applied a full retrospective transition approach. See Note 3 for transition disclosures related to the adoption of this ASU.

Adoption of ASU 2018-12 [Abstract]
Adoption of ASU 2018-12	3. Adoption of ASU 2018-12 On January 1, 2023, we adopted FASB Accounting Standards Update (“ASU”) 2018-12, Targeted Improvements to the Accounting for Long-Duration Contracts and related amendments (“ASU 2018-12”) with a transition date of January 1, 2021. ASU 2018-12 updated accounting and reporting requirements for long-duration contracts and certain investment contracts issued by insurance entities. We adopted ASU 2018-12 under the modified retrospective approach, except for MRBs, which applied the full retrospective approach. Our consolidated financial statements are presented under the new guidance for reporting periods beginning January 1, 2021. Under ASU 2018-12, we include actual historical cash flows along with best estimate future cash flows to derive the net premium ratio when calculating the LFPB associated with our traditional and limited-payment long-duration contracts. We review and update, if necessary, assumptions used to measure future cash flows included in the net premium ratio at least annually. Historical cash flows included in the net premium ratio are updated for actual experience quarterly and as assumptions are updated. Changes in the measurement of our LFPB result from updates to cash flow assumptions and actual experience, which impacts are reported within policyholder remeasurement gain (loss) on our Consolidated Statements of Comprehensive Income (Loss). We use an upper-medium grade (low credit risk) fixed-income instrument yield (single-A) discount rate when calculating the LFPB. This discount rate is updated quarterly at each reporting date with the impact recognized in OCI. ASU 2018-12 also eliminated loss recognition testing, premium deficiency testing and the provision for adverse deviation for LFPB. ASU 2018-12 introduced the category of MRBs, which are contracts or contract features that provide protection to the policyholder from other-than-nominal capital market risk and expose us to other-than-nominal capital market risk upon the occurrence of a specific event or circumstance, such as death, annuitization or periodic withdrawal. MRBs are required to be measured at fair value, with periodic changes in fair value reported within MRB gain (loss) on our Consolidated Statements of Comprehensive Income (Loss), except for periodic changes to instrument-specific credit risk related to direct policies, which are recognized in OCI. Changes in the fair value of ceded MRB assets and liabilities are also reported within MRB gain (loss) on our Consolidated Statements of Comprehensive Income (Loss). ASU 2018-12 simplified the amortization model for DAC and DAC-like intangible balances, including VOBA, DSI and DFEL. Historically these balances were amortized in proportion to premium or over expected gross profits. They are now amortized on a constant-level basis over the expected term of the contract. Loss recognition testing and impairment testing are no longer applicable for DAC. ASU 2018-12 requires disaggregated rollforwards of the beginning of year to the end of the reporting period balances. We also disclose information about inputs, judgments, assumptions, methods, changes during the period and the effect of these changes on the measurement of applicable balances. In determining the appropriate level of aggregation, we considered our reportable segments, nature and risk characteristics of our products and level of aggregation we used in disclosures presented outside the financial statements. The following table presents the cumulative effect adjustments (in millions), after-tax and shown as increase (decrease), to the components of stockholder’s equity due to the adoption of ASU 2018-12 as of January 1, 2021, by primary accounting topic: Total Retained Stockholder’s Earnings AOCI Equity Shadow impacts: DAC, VOBA, DSI and DFEL $ - $ 2,271 $ 2,271 Additional liabilities for other insurance benefits - 1,197 1,197 LFPB and Other (1) ( 121 ) ( 1,520 ) ( 1,641 ) MRBs (2) ( 1,699 ) 2,874 1,175 Total $ ( 1,820 ) $ 4,822 $ 3,002 (1) Includes impacts to reserves and ceded reserves reported within future contract benefits and reinsurance recoverables, respectively on the Consolidated Balance Sheets, excluding shadow impacts on additional liabilities for other insurance benefits.

The fair value, gross unrealized losses (in millions) and number of fixed maturity AFS securities where the fair value had declined and remained below amortized cost by greater than 20% were as follows: As of March 31, 2023 Gross Number Fair Unrealized of Value Losses Securities (1) Less than six months $ 2,411 $ 690 359 Six months or greater, but less than nine months 4,356 1,429 691 Nine months or greater, but less than twelve months 4,300 1,924 627 Twelve months or greater 374 226 85 Total $ 11,441 $ 4,269 1,762 As of December 31, 2022 Gross Number Fair Unrealized of Value Losses Securities (1) Less than six months $ 10,895 $ 3,514 1,489 Six months or greater, but less than nine months 4,256 2,150 640 Nine months or greater, but less than twelve months 362 243 73 Twelve months or greater 2 - 15 Total $ 15,515 $ 5,907 2,217 (1) We may reflect a security in more than one aging category based on various purchase dates. Our gross unrealized losses on fixed maturity AFS securities decreased by $ 1.9 billion for the three months ended March 31 , 2023. As discussed further below, we believe the unrealized loss position as of March 31 , 2023, did not require an impairment recognized in earnings as (i) we did not intend to sell these fixed maturity AFS securities; (ii) it is not more likely than not that we will be required to sell the fixed maturity AFS securities before recovery of their amortized cost basis; and (iii) the difference in the fair value compared to the amortized cost was due to factors other than credit loss. Based upon this evaluation as of March 31 , 2023, management believes we have the ability to generate adequate amounts of cash from our normal operations (e.g., insurance premiums, fee income and investment income) to meet cash requirements with a prudent margin of safety without requiring the sale of our impaired securities. As of March 31, 2023, the unrealized losses associated with our corporate bond, U.S. government bond, state and municipal bond and foreign government bond securities were attributable primarily to rising interest rates and widening credit spreads since purchase. We performed a detailed analysis of the financial performance of the underlying issuers and determined that we expected to recover the entire amortized cost of each impaired security. Credit ratings express opinions about the credit quality of a security. Securities rated investment grade (those rated BBB- or higher by S&P Global Ratings (“S&P”) or Baa3 or higher by Moody’s Investors Service (“Moody’s”)) are generally considered by the rating agencies and market participants to be low credit risk. As of March 31, 2023, and December 31, 2022, 96 % of the fair value of our corporate bond portfolio was rated investment grade. As of March 31, 2023, and December 31, 2022, the portion of our corporate bond portfolio rated below investment grade had an amortized cost of $ 3.3 billion and $ 3.5 billion, respectively, and a fair value of $ 3.1 billion and $ 3.3 billion, respectively. Based upon the analysis discussed above, we believe that as of March 31, 2023, and December 31, 2022, we would have recovered the amortized cost of each corporate bond. As of March 31, 2023, the unrealized losses associated with our MBS and ABS were attributable primarily to rising interest rates and widening credit spreads since purchase. We assessed for credit impairment using a cash flow model that incorporates key assumptions including default rates, severities and prepayment rates. We estimated losses for a security by forecasting the underlying loans in each transaction. The forecasted loan performance was used to project cash flows to the various tranches in the structure, as applicable. Our forecasted cash flows also considered, as applicable, independent industry analyst reports and forecasts and other independent market data. Based upon our assessment of the expected credit losses of the security given the performance of the underlying collateral compared to our subordination or other credit enhancement, we expected to recover the entire amortized cost of each impaired security. As of March 31 , 2023, the unrealized losses associated with our hybrid and redeemable preferred securities were attributable primarily to wider credit spreads caused by illiquidity in the market and subordination within the capital structure, as well as credit risk of underlying issuers. For our hybrid and redeemable preferred securities, we evaluated the financial performance of the underlying issuers based upon credit performance and investment ratings and determined that we expected to recover the entire amortized cost of each impaired security. Credit Loss Impairment on Fixed Maturity AFS Securities We regularly review our fixed maturity AFS securities for declines in fair value that we determine to be impairment-related, including those attributable to credit risk factors that may require an allowance for credit losses. Changes in the allowance for credit losses on fixed maturity AFS securities (in millions), aggregated by investment category, were as follows: For the Three Months Ended March 31, 2023 Corporate Bonds RMBS Other Total Balance as of beginning-of-year $ 9 $ 7 $ 5 $ 21 Additions from purchases of PCD debt securities (1) - - - - Additions for securities for which credit losses were not previously recognized 18 - - 18 Additions (reductions) for securities for which credit losses were previously recognized - ( 1 ) - ( 1 ) Reductions for securities disposed ( 1 ) - - ( 1 ) Balance as of end-of-period (2) $ 26 $ 6 $ 5 $ 37 For the Three Months Ended March 31, 2022 Corporate Bonds RMBS Other Total Balance as of beginning-of-year $ 17 $ 1 $ 1 $ 19 Additions from purchases of PCD debt securities (1) - - - - Additions for securities for which credit losses were not previously recognized - 1 1 2 Reductions for securities disposed ( 1 ) - - ( 1 ) Balance as of end-of-period (2) $ 16 $ 2 $ 2 $ 20 (1) Represents purchased credit-deteriorated (“PCD”) fixed maturity AFS securities.

Variable Interest Entities

Variable Interest Entities	3 Months Ended

Variable Interest Entities [Abstract]
Variable Interest Entities	5. Variable Inte rest Entities Unconsolidated Variable Interest Entities Structured Securities Through our investment activities, we make passive investments in structured securities issued by variable interest entities (“VIEs”) for which we are not the manager. These structured securities include our asset-backed securities (“ABS”), residential mortgage-backed securities (“RMBS”) and commercial mortgage-backed securities (“CMBS”). We have not provided financial or other support with respect to these VIEs other than our original investment. We have determined that we are not the primary beneficiary of these VIEs due to the relative size of our investment in comparison to the principal amount of the structured securities issued by the VIEs and the level of credit subordination that reduces our obligation to absorb losses or right to receive benefits. Our maximum exposure to loss on these structured securities is limited to the amortized cost for these investments. We recognize our variable interest in these VIEs at fair value on our Consolidated Balance Sheets. For information about these structured securities, see Note 5. Limited Partnerships and Limited Liability Companies We invest in certain limited partnerships (“LPs”) and limited liability companies (“LLCs”) that we have concluded are VIEs. Our exposure to loss is limited to the capital we invest in the LPs and LLCs. We do not hold any substantive kick-out or participation rights in the LPs and LLCs, and we do not receive any performance fees or decision maker fees from the LPs and LLCs. Based on our analysis of the LPs and LLCs, we are not the primary beneficiary of the VIEs as we do not have the power to direct the most significant activities of the LPs and LLCs. The carrying amounts of our investments in the LPs and LLCs are recognized in other investments on our Consolidated Balance Sheets and were $ 3.0 billion as of March 31 , 2023, and December 31, 2022.

Derivative Instruments

Derivative Instruments	3 Months Ended

Derivative Instruments [Abstract]
Derivative Instruments	6. Derivative Instruments We maintain an overall risk management strategy that incorporates the use of derivative instruments to minimize significant unplanned fluctuations in earnings that are caused by interest rate risk, foreign currency exchange risk, equity market risk, basis risk, commodity risk and credit risk. We assess these risks by continually identifying and monitoring changes in our exposures that may adversely affect expected future cash flows and by evaluating hedging opportunities. Derivative activities are monitored by various management committees. The committees are responsible for overseeing the implementation of various hedging strategies that are developed through the analysis of financial simulation models and other internal and industry sources. The resulting hedging strategies are incorporated into our overall risk management strategies. See Note 12 for additional disclosures related to the fair value of our derivative instruments. Interest Rate Contracts We use derivative instruments as part of our interest rate risk management strategy. These instruments are economic hedges unless otherwise noted and include: Forward-Starting Interest Rate Swaps We use forward-starting interest rate swaps to hedge the interest rate exposure within our life and annuity products. Interest Rate Cap Corridors We use interest rate cap corridors to provide a level of protection from the effect of rising interest rates for certain life insurance products and annuity contracts. Interest rate cap corridors involve purchasing an interest rate cap at a specific cap rate and selling an interest rate cap with a higher cap rate. For each corridor, the amount of quarterly payments, if any, is determined by the rate at which the underlying index rate resets above the original capped rate. The corridor limits the benefit the purchaser can receive as the related interest rate index rises above the higher capped rate. There is no additional liability to us other than the purchase price associated with the interest rate cap corridor. Interest Rate Futures We use interest rate futures contracts to hedge the liability exposure on certain options in variable annuity products. These futures contracts require payment between our counterparty and us on a daily basis for changes in the futures index price. Interest Rate Swap Agreements We use interest rate swap agreements to hedge the liability exposure on certain options in variable annuity products. We also use interest rate swap agreements designated and qualifying as cash flow hedges to hedge the interest rate risk of floating-rate bond coupon payments by replicating a fixed-rate bond. Finally, we use interest rate swap agreements designated and qualifying as fair value hedges to hedge against changes in the fair value of certain fixed maturity securities due to interest rate risks. Reverse Treasury Locks We use reverse treasury locks designated and qualifying as cash flow hedges to hedge the interest rate exposure related to the anticipated purchase of fixed-rate securities or the anticipated future cash flows of floating-rate fixed maturity securities due to changes in interest rates. These derivatives are primarily structured to hedge interest rate risk inherent in the assumptions used to price certain liabilities. Foreign Currency Contracts We use derivative instruments as part of our foreign currency risk management strategy. These instruments are economic hedges unless otherwise noted and include: Currency Futures We use currency futures to hedge foreign exchange risk associated with certain options in variable annuity products. Currency futures exchange one currency for another at a specified date in the future at a specified exchange rate. Foreign Currency Swaps We use foreign currency swaps to hedge foreign exchange risk of investments in fixed maturity securities denominated in foreign currencies. A foreign currency swap is a contractual agreement to exchange one currency for another at specified dates in the future at a specified exchange rate. We also use foreign currency swaps designated and qualifying as cash flow hedges to hedge foreign exchange risk of investments in fixed maturity securities denominated in foreign currencies. Foreign Currency Forwards We use foreign currency forwards to hedge foreign exchange risk of investments in fixed maturity securities denominated in foreign currencies. A foreign currency forward is a contractual agreement to exchange one currency for another at specified dates in the future at a specified current exchange rate. Equity Market Contracts We use derivative instruments as part of our equity market risk management strategy that are economic hedges and include: Call Options Based on the S&P 500 ® Index and Other Indices We use call options to hedge the liability exposure on certain options in variable annuity, indexed variable annuity, fixed indexed annuity, IUL and VUL products. Our indexed annuity and IUL contracts permit the holder to elect an interest rate return or an equity market component, where interest credited to the contracts is linked to the performance of the S&P 500 Index or other indices. Policyholders may elect to rebalance index options at renewal dates. At the end of each indexed term, which can be up to six years, we have the opportunity to re-price the indexed component by establishing participation rates, caps, spreads and specified rates, subject to contractual guarantees. We use call options that are highly correlated to the portfolio allocation decisions of our policyholders, such that we are economically hedged with respect to equity returns for the current reset period. Consumer Price Index Swaps We use consumer price index swaps to hedge the liability exposure on certain options in fixed annuity products. Consumer price index swaps are contracts entered into at no cost and whose payoff is the difference between the consumer price index inflation rate and the fixed-rate determined as of inception. Equity Futures We use equity futures contracts to hedge the liability exposure on certain options in variable annuity products. These futures contracts require payment between our counterparty and us on a daily basis for changes in the futures index price. Put Options We use put options to hedge the liability exposure on certain options in variable annuity, indexed variable annuity and VUL products. Put options are contracts that require buyers to pay at a specified future date the amount, if any, by which a specified equity index is less than the strike rate stated in the agreement, applied to a notional amount. Total Return Swaps We use total return swaps to hedge the liability exposure on certain options in variable annuity products and indexed variable annuity products. In addition, we use total return swaps to hedge a portion of the liability related to our deferred compensation plans. We receive the total return on a portfolio of indexes and pay a floating-rate of interest. Commodity Contracts We use commodity contracts to economically hedge certain investments that are closely tied to the changes in commodity values. The commodity contract is an over-the-counter contract that combines a purchase put/sold call to lock in a commodity price within a predetermined range in exchange for a net premium. Credit Contracts We use derivative instruments as part of our credit risk management strategy that are economic hedges and include: Credit Default Swaps – Buying Protection We use credit default swaps (“CDSs”) to hedge the liability exposure on certain options in variable annuity products. We buy CDSs to hedge against a drop in bond prices due to credit concerns of certain bond issuers. A CDS allows us to put the bond back to the counterparty at par upon a default event by the bond issuer. A default event is defined as bankruptcy, failure to pay, obligation acceleration or restructuring. CDSs – Selling Protection We use CDSs to hedge the liability exposure on certain options in variable annuity products. We sell CDSs to offer credit protection to policyholders and investors. The CDSs hedge the policyholders and investors against a drop in bond prices due to credit concerns of certain bond issuers. A CDS allows the investor to put the bond back to us at par upon a default event by the bond issuer. A default event is defined as bankruptcy, failure to pay, obligation acceleration or restructuring. Other Derivatives Lapse Protection Rider Ceded Derivative We also have an inter-company agreement through which LNBAR, an affiliated insurer, assumes the risk under certain UL contracts for lapse protection riders (“LPR”). If the policyholder’s account balance is insufficient to pay the cost of insurance charges required to keep the policy in force, and the policyholder has made the required deposits, we will be reimbursed for those charges. Embedded Derivatives We have embedded derivatives that include: Indexed Annuity and IUL Contracts Embedded Derivatives Our indexed annuity and IUL contracts permit the holder to elect an interest rate return or an equity market component, where interest credited to the contracts is linked to the performance of the S&P 500 ® Index or other indices. Policyholders may elect to rebalance index options at renewal dates. At the end of each indexed term, which can be up to six years , we have the opportunity to re-price the indexed component by establishing participation rates, caps, spreads and specified rates, subject to contractual guarantees. We use options that are highly correlated to the portfolio allocation decisions of our policyholders, such that we are economically hedged with respect to equity returns for the current reset period. Reinsurance-Related Embedded Derivatives We have certain modified coinsurance and coinsurance with funds withheld reinsurance agreements with embedded derivatives related to the withheld assets of the related funds. These derivatives are considered total return swaps with contractual returns that are attributable to various assets and liabilities associated with these reinsurance agreements. We have derivative instruments with off-balance-sheet risks whose notional or contract amounts exceed the related credit exposure. Outstanding derivative instruments with off-balance-sheet risks (in millions) were as follows: As of March 31, 2023 As of December 31, 2022 Notional Fair Value Notional Fair Value Amounts Asset Liability Amounts Asset Liability Qualifying Hedges Cash flow hedges: Interest rate contracts (1) $ 1,082 $ 6 $ 143 $ 1,377 $ 4 $ 232 Foreign currency contracts (1) 4,400 637 19 4,383 643 18 Total cash flow hedges 5,482 643 162 5,760 647 250 Fair value hedges: Interest rate contracts (1) 484 1 61 524 2 44 Non-Qualifying Hedges Interest rate contracts (1) 83,299 607 764 105,977 709 935 Foreign currency contracts (1) 363 19 2 395 27 2 Equity market contracts (1) 215,376 6,372 2,837 142,653 5,135 2,035 Commodity contracts (1) 13 23 - 13 14 3 Credit contracts (1) 122 - - - - - LPR ceded derivative (2) - 199 - - 212 - Embedded derivatives: Reinsurance-related (3) - 614 - - 681 - Indexed annuity and IUL contracts (3) (4) - 305 5,796 - 525 4,783 Total derivative instruments $ 305,139 $ 8,783 $ 9,622 $ 255,322 $ 7,952 $ 8,052 (1) These asset and liability balances are presented on a gross basis.

(2) As of March 31, 2023, the latest maturity date for which we were hedging our exposure to the variability in future cash flows for these instruments was June 16, 2061 . The following amounts (in millions) were recorded on the Consolidated Balance Sheets related to cumulative basis adjustments for fair value hedges: Cumulative Fair Value Hedging Adjustment Included in the Amortized Cost of the Amortized Cost of the Hedged Hedged Assets / (Liabilities) Assets / (Liabilities) As of As of As of As of March 31, December 31, March 31, December 31, 2023 2022 2023 2022 Line Item in the Consolidated Balance Sheets in which the Hedged Item is Included Fixed maturity AFS securities, at fair value $ 556 $ 587 $ 60 $ 44 The change in our unrealized gain (loss) on derivative instruments within accumulated other comprehensive income (loss) (“AOCI”) (in millions) was as follows: For the Three Months Ended March 31, 2023 2022 Unrealized Gain (Loss) on Derivative Instruments Balance as of beginning-of-year $ 301 $ 258 Other comprehensive income (loss): Unrealized holding gains (losses) arising during the period: Cash flow hedges: Interest rate contracts 110 ( 142 ) Foreign currency contracts 76 ( 17 ) Change in foreign currency exchange rate adjustment ( 67 ) 75 Income tax benefit (expense) ( 25 ) 18 Less: Reclassification adjustment for gains (losses) included in net income (loss): Cash flow hedges: Interest rate contracts (1) - 1 Foreign currency contracts (1) 14 13 Foreign currency contracts (2) 2 3 Income tax benefit (expense) ( 3 ) ( 4 ) Balance as of end-of-period $ 382 $ 179 (1) The OCI offset is reported within net investment income on the Consolidated Statements of Comprehensive Income (Loss). (2) The OCI offset is reported within realized gain (loss) on the Consolidated Statements of Comprehensive Income (Loss).

This reclassification would be due primarily to interest rate variances related to our interest rate swap agreements. For the three months ended March 31, 2023 and 2022, there were no material reclassifications to earnings due to hedged firm commitments no longer deemed probable or due to hedged forecasted transactions that had not occurred by the end of the originally specified time period. As of March 31, 2023 and December 31, 2022, we did not have any exposure related to CDSs for which we are the seller. Credit Risk We are exposed to credit losses in the event of non-performance by our counterparties on various derivative contracts and reflect assumptions regarding the credit or non-performance risk. The non-performance risk is based upon assumptions for each counterparty’s credit spread over the estimated weighted average life of the counterparty exposure, less collateral held. As of March 31, 2023 , the non-performance risk adjustment was zero . The credit risk associated with such agreements is minimized by entering into agreements with financial institutions with long-standing, superior performance records. Additionally, we maintain a policy of requiring derivative contracts to be governed by an International Swaps and Derivatives Association (“ISDA”) Master Agreement. We are required to maintain minimum ratings as a matter of routine practice in negotiating ISDA agreements. Under some ISDA agreements, we and LLANY have agreed to maintain certain financial strength or claims-paying ratings. A downgrade below these levels could result in termination of derivative contracts, at which time any amounts payable by us would be dependent on the market value of the underlying derivative contracts. In certain transactions, we and the counterparty have entered into a credit support annex requiring either party to post collateral when net exposures exceed pre-determined thresholds. These thresholds vary by counterparty and credit rating. The amount of such exposure is essentially the net replacement cost or market value less collateral held for such agreements with each counterparty if the net market value is in our favor. We did no t have any exposure as of March 31, 2023 , or December 31, 2022. The amounts recognized (in millions) by S&P credit rating of counterparty, for which we had the right to reclaim cash collateral or were obligated to return cash collateral, were as follows: As of March 31, 2023 As of December 31, 2022 Collateral Collateral Collateral Collateral Posted by Posted by Posted by Posted by S&P Counter- LNL Counter- LNL Credit Party (Held by Party (Held by Rating of (Held by Counter- (Held by Counter- Counterparty LNL) Party) LNL) Party) AA- $ 510 $ ( 5 ) $ 383 $ ( 6 ) A+ 1,781 ( 97 ) 1,718 ( 151 ) A 1,229 ( 5 ) 1,099 - $ 3,520 $ ( 107 ) $ 3,200 $ ( 157 ) Balance Sheet Offsetting Information related to the effects of offsetting on the Consolidated Balance Sheets (in millions) was as follows: As of March 31, 2023 Embedded Derivative Derivative Instruments Instruments Total Financial Assets Gross amount of recognized assets $ 7,664 $ 919 $ 8,583 Gross amounts offset ( 3,676 ) - ( 3,676 ) Net amount of assets 3,988 919 4,907 Gross amounts not offset: Cash collateral ( 3,520 ) - ( 3,520 ) Non-cash collateral (1) ( 468 ) - ( 468 ) Net amount $ - $ 919 $ 919 Financial Liabilities Gross amount of recognized liabilities $ 150 $ 5,796 $ 5,946 Gross amounts offset ( 1 ) - ( 1 ) Net amount of liabilities 149 5,796 5,945 Gross amounts not offset: Cash collateral ( 107 ) - ( 107 ) Non-cash collateral (2) - - - Net amount $ 42 $ 5,796 $ 5,838 (1) Excludes excess non-cash collateral received of $ 730 million, as the collateral offset is limited to the net estimated fair value of derivatives after application of netting arrangements.

(2) Consists primarily of the update of fund mapping, volatility and other capital market assumptions. (3) Net amount at risk (“NAR”) is the current guaranteed minimum benefit in excess of the current account balance as of the balance sheet date. For GLBs, the guaranteed minimum benefit is calculated based on the present value of GLB payments. Our variable annuity products may offer more than one type of guaranteed benefit rider to a policyholder. In instances where more than one guaranteed benefit feature exists in a contract, the guaranteed benefit rider that provides the highest NAR is used in the calculation. For the year ended December 31, 2022, Variable Annuities had a favorable impact from updates to policyholder benefit utilization behavior and fund mapping and volatility assumptions. Fixed Annuities and Retirement Plan Services did not have any significant assumption updates. See “MRBs” in Note 1 and Note 12 for details related to our fair value judgments, assumptions, inputs and valuation methodology.

Considerable judgment is required to develop these assumptions used to measure fair value. Accordingly, the estimates shown are not necessarily indicative of the amounts that would be realized in a one-time, current market exchange of all of our financial instruments. Mortgage Loans on Real Estate The fair value of mortgage loans on real estate, excluding mortgage loans accounted for using the fair value option, is established using a discounted cash flow method based on credit rating, maturity and future income. The ratings for mortgages in good standing are based on property type, location, market conditions, occupancy, debt-service coverage, loan-to-value, quality of tenancy, borrower and payment record. The fair value for impaired mortgage loans is based on the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s market price or the fair value of the collateral if the loan is collateral dependent. The inputs used to measure the fair value of our mortgage loans on real estate, excluding mortgage loans accounted for using the fair value option, are classified as Level 2 within the fair value hierarchy. Other Investments The carrying value of our assets classified as other investments, excluding short-term investments, approximates fair value. Other investments includes primarily LPs and other privately held investments that are accounted for using the equity method of accounting and the carrying value is based on our proportional share of the net assets of the LPs. Other investments also includes FHLB stock carried at cost and periodically evaluated for impairment based on ultimate recovery of par value. The inputs used to measure the fair value of our LPs, other privately held investments and FHLB stock are classified as Level 3 within the fair value hierarchy. The remaining assets in other investments include cash collateral receivables and securities that are not LPs or other privately held investments. The inputs used to measure the fair value of these assets are classified as Level 2 within the fair value hierarchy. Separate Account Assets Separate account assets are primarily carried at fair value. A portion of our separate account assets includes LPs, which are accounted for using the equity method of accounting. The carrying value is based on our proportional share of the net assets of the LPs and approximates fair value. The inputs used to measure the fair value of the separate account asset LPs are classified as Level 3 within the fair value hierarchy. Policyholder Account Balances Policyholder account balances include account balances of certain investment contracts. The fair value of the account balances of certain investment contracts is based on their approximate surrender value as of the balance sheet date. The inputs used to measure the fair value of these policyholder account balances are classified as Level 3 within the fair value hierarchy. Other Liabilities Other liabilities include remaining guaranteed interest and similar contracts. The fair value for the remaining guaranteed interest and similar contracts is estimated using discounted cash flow calculations as of the balance sheet date. These calculations are based on interest rates currently offered on similar contracts with maturities that are consistent with those remaining for the contracts being valued. As of March 31, 2023, and December 31, 2022, the remaining guaranteed interest and similar contracts carrying value approximated fair value. The inputs used to measure the fair value of these other liabilities are classified as Level 3 within the fair value hierarchy. Short-Term and Long-Term Debt The fair value of short-term and long-term debt is based on quoted market prices. The inputs used to measure the fair value of our short-term and long-term debt are classified as Level 2 within the fair value hierarchy. Fair Value Option Mortgage loans on real estate, net of allowance for credit losses, as reported on the Consolidated Balance Sheets, includes mortgage loans on real estate for which the fair value option was elected. The fair value option allows us to elect fair value as an alternative measurement for mortgage loans not otherwise reported at fair value. We have made these elections for certain mortgage loans associated with modified coinsurance agreements to help mitigate the inconsistency in earnings that would otherwise result from the use of embedded derivatives included with these loans. Changes in fair value are reflected in realized gain (loss) on the Consolidated Statement of Comprehensive Income (Loss). Changes in fair value due to instrument-specific credit risk are estimated using changes in credit spreads and quality ratings for the period reported. Mortgage loans on real estate for which the fair value option was elected are valued using third-party pricing services. We have procedures in place to review the valuations each quarter to ensure they are reasonable, including utilizing a separate third party to reperform the valuation for a selection of mortgage loans on an annual basis. Due to lack of observable inputs, mortgage loans electing the fair value option are classified as Level 3 within the fair value hierarchy. The fair value and aggregate contractual principal for mortgage loans on real estate where the fair value option was elected (in millions) were as follows: As of As of March 31, December 31, 2023 2022 Fair value $ 490 $ 487 Aggregate contractual principal 515 514 As of March 31, 2023, and December 31, 2022, no loans for which the fair value option was elected were in non-accrual status, and no ne were more than 90 days past due and still accruing interest. Financial Instruments Carried at Fair Value We did no t have any assets or liabilities measured at fair value on a nonrecurring basis as of March 31, 2023, or December 31, 2022.

(2) The liquidity/duration adjustment input represents an estimated market participant composite of adjustments attributable to liquidity premiums, expected durations, structures and credit quality that would be applied to the market observable information of an investment. (3) The lapse input represents the estimated probability of a contract surrendering during a year, and thereby forgoing any future benefits. The range for indexed annuity contracts represents the lapses during the surrender charge period. (4) The utilization of GLB withdrawals input represents the estimated percentage of policyholders that utilize the GLB withdrawal riders. (5) The utilization factors are applied to the present value of claims or premiums, as appropriate, in the MRB calculation to estimate the impact of inefficient GLB withdrawal behavior, including taking less than or more than the maximum GLB withdrawal. (6) The non-performance risk input represents the estimated additional credit spread that market participants would apply to the market observable discount rate when pricing a contract. The non-performance risk input was weighted by the absolute value of the sensitivity of the reserve to the non-performance risk assumption. The non-performance risk input for LPR ceded derivative was weighted using a simple average. (7) The mortality input represents the estimated probability of when an individual belonging to a particular group, categorized according to age or some other factor such as gender, will die. (8) The volatility input represents overall volatilities assumed for the underlying variable annuity funds, which include a mixture of equity and fixed-income assets. Volatility assumptions vary by fund due to the benchmarking of different indices. The volatility input was weighted by the relative account value assigned to each index. (9) The mortality is based on a combination of company and industry experience, adjusted for improvement factors. (10) A weighted average input range is not a meaningful measurement for lapse, utilization factors or mortality. From the table above, we have excluded Level 3 fair value measurements obtained from independent, third-party pricing sources. We do not develop the significant inputs used to measure the fair value of these assets and liabilities, and the information regarding the significant inputs is not readily available to us. Independent broker-quoted fair values are non-binding quotes developed by market makers or broker-dealers obtained from third-party sources recognized as market participants. The fair value of a broker-quoted asset or liability is based solely on the receipt of an updated quote from a single market maker or a broker-dealer recognized as a market participant as we do not adjust broker quotes when used as the fair value measurement for an asset or liability. Significant increases or decreases in any of the quotes received from a third-party broker-dealer may result in a significantly higher or lower fair value measurement. Changes in any of the significant inputs presented in the table above would have resulted in a significant change in the fair value measurement of the asset or liability as follows:  Investments – An increase in the liquidity/duration adjustment input would have resulted in a decrease in the fair value measurement.  Indexed annuity contracts embedded derivatives – For direct embedded derivatives, an increase in the lapse or mortality inputs would have resulted in a decrease in the fair value measurement.  LPR ceded derivative – Assuming our LPR ceded derivative is in an asset position: an increase in our lapse, non-performance risk or mortality inputs would have resulted in an increase in the fair value measurement.  MRBs – Assuming our market risk benefits are in a liability position: an increase in our lapse, non-performance risk or mortality inputs would have resulted in a decrease in the fair value measurement except for policies with GDB riders only, an increase in mortality would have resulted in an increase in the fair value measurement. For each category discussed above, the unobservable inputs are not inter-related; therefore, a directional change in one input would not have affected the other inputs. As part of our ongoing valuation process, we assess the reasonableness of our valuation techniques or models and make adjustments as necessary.

Contingencies and Commitments [Abstract]
Contingencies and Commitments	13. Contingencies and Commit ments Contingencies Reinsurance Disputes Certain reinsurers have sought rate increases on certain yearly renewable term agreements. We are disputing the requested rate increases under these agreements. We may initiate legal proceedings, as necessary, under these agreements in order to protect our contractual rights. Additionally, reinsurers have initiated, and may in the future initiate, legal proceedings against us. While this may impact the Life Insurance segment, we believe it is unlikely the outcome of these disputes would have a material impact on the consolidated financial statements. Regulatory and Litigation Matters Regulatory bodies, such as state insurance departments, the SEC, Financial Industry Regulatory Authority and other regulatory bodies regularly make inquiries and conduct examinations or investigations concerning our compliance with, among other things, insurance laws, securities laws, laws governing the activities of broker-dealers, registered investment advisers and unclaimed property laws. LNL and its affiliates are involved in various pending or threatened legal or regulatory proceedings, including purported class actions, arising from the conduct of business both in the ordinary course and otherwise. In some of the matters, very large and/or indeterminate amounts, including punitive and treble damages, are sought. Modern pleading practice in the U.S. permits considerable variation in the assertion of monetary damages or other relief. Jurisdictions may permit claimants not to specify the monetary damages sought or may permit claimants to state only that the amount sought is sufficient to invoke the jurisdiction of the trial court. In addition, jurisdictions may permit plaintiffs to allege monetary damages in amounts well exceeding verdicts obtained in the jurisdiction for similar matters. This variability in pleadings, together with the actual experiences of LNL in litigating or resolving through settlement numerous claims over an extended period of time, demonstrates to management that the monetary relief which may be specified in a lawsuit or claim bears little relevance to its merits or disposition value. Due to the unpredictable nature of litigation, the outcome of a litigation matter and the amount or range of potential loss at particular points in time is normally difficult to ascertain. Uncertainties can include how fact finders will evaluate documentary evidence and the credibility and effectiveness of witness testimony, and how trial and appellate courts will apply the law in the context of the pleadings or evidence presented, whether by motion practice, or at trial or on appeal. Disposition valuations are also subject to the uncertainty of how opposing parties and their counsel will themselves view the relevant evidence and applicable law. We establish liabilities for litigation and regulatory loss contingencies when information related to the loss contingencies shows both that it is probable that a loss has been incurred and the amount of the loss can be reasonably estimated. It is possible that some matters could require us to pay damages or make other expenditures or establish accruals in amounts that could not be estimated as of March 31, 2023. For some matters, the Company is able to estimate a reasonably possible range of loss. For such matters in which a loss is probable, an accrual has been made. For such matters where a loss is believed to be reasonably possible, but not probable, no accrual has been made. Accordingly, the estimate contained in this paragraph reflects two types of matters. For some matters included within this estimate, an accrual has been made, but there is a reasonable possibility that an exposure exists in excess of the amount accrued. In these cases, the estimate reflects the reasonably possible range of loss in excess of the accrued amount. For other matters included within this estimation, no accrual has been made because a loss, while potentially estimable, is believed to be reasonably possible but not probable. In these cases, the estimate reflects the reasonably possible loss or range of loss. As of March 31, 2023 , we estimate the aggregate range of reasonably possible losses, including amounts in excess of amounts accrued for these matters as of such date, to be up to approximately $ 190 million, after-tax. Any estimate is not an indication of expected loss, if any, or of the Company’s maximum possible loss exposure on such matters. For other matters, we are not currently able to estimate the reasonably possible loss or range of loss. We are 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 other parties and investigation of factual allegations, rulings by the court on motions or appeals, analysis by experts and the progress of settlement negotiations. On a quarterly and annual basis, we review relevant information with respect to litigation contingencies and update our accruals, disclosures and estimates of reasonably possible losses or ranges of loss based on such reviews . Among other matters, we are presently engaged in litigation, including relating to cost of insurance rates (“Cost of Insurance and Other Litigation”), as described below. No accrual has been made for some of these matters. Although a loss is believed to be reasonably possible for these matters, for some of these matters, we are not able to estimate a reasonably possible amount or range of potential liability. An adverse outcome in one or more of these matters may have a material impact on the consolidated financial statements, but, based on information currently known, management does not believe those cases are likely to have such an impact. Cost of Insurance and Other Litigation Cost of Insurance Litigation Glover v. Connecticut General Life Insurance Company and The Lincoln National Life Insurance Company , filed in the U.S. District Court for the District of Connecticut, No. 3:16-cv-00827, is a putative class action that was served on LNL on June 8, 2016. Plaintiff is the owner of a universal life insurance policy who alleges that LNL charged more for non-guaranteed cost of insurance than permitted by the policy. Plaintiff seeks to represent all universal life and variable universal life policyholders who owned policies containing non-guaranteed cost of insurance provisions that are similar to those of Plaintiff’s policy and seeks damages on behalf of all such policyholders. On January 11, 2019, the court dismissed Plaintiff’s complaint in its entirety. In response, Plaintiff filed a motion for leave to amend the complaint, which we have opposed . EFG Bank AG, Cayman Branch, et al. v. The Lincoln National Life Insurance Company , pending in the U.S. District Court for the Eastern District of Pennsylvania, No. 2:17-cv-02592, is a civil action filed on February 1, 2017. Plaintiffs own universal life insurance policies originally issued by Jefferson-Pilot (now LNL). Plaintiffs allege that LNL breached the terms of policyholders’ contracts when it increased non-guaranteed cost of insurance rates beginning in 2016. We are vigorously defending this matter. In re: Lincoln National COI Litigation , pending in the U.S. District Court for the Eastern District of Pennsylvania, Case No. 2:16-cv-06605-GJP, is a consolidated litigation matter related to multiple putative class action cases that were consolidated by an order dated March 20, 2017. Plaintiffs purport to own certain universal life insurance policies originally issued by Jefferson-Pilot (now LNL). Among other things, plaintiffs allege that LNL and LNC breached the terms of policyholders’ contracts by increasing non-guaranteed cost of insurance rates beginning in 2016. Plaintiffs sought to represent classes of policyowners and sought damages on their behalf. On August 9, 2022, the court denied plaintiffs’ motion for class certification. The parties participated in a mediation on December 13, 2022, and subsequently reached a settlement. On January 26, 2023, the parties informed the presiding judge of a class settlement in this action, subject to final documentation and court approval. On March 24, 2023, plaintiffs filed a motion for preliminary approval of the class settlement. The provisional settlement, which is subject to both preliminary and final approval of the court, consists of $ 117.75 million in pre-tax cash (in the aggregate for both this litigation and the In re: Lincoln National 2017 COI Rate Litigation matter discussed immediately below) and a five-year cost of insurance rate freeze, among other terms. In re: Lincoln National 2017 COI Rate Litigation , pending in the U.S. District Court for the Eastern District of Pennsylvania, Case No. 2:17-cv-04150, is a consolidated litigation matter related to multiple putative class action cases that were consolidated by an order dated March 28, 2018. Plaintiffs purport to own certain universal life insurance policies originally issued by Jefferson-Pilot (now LNL). Among other things, plaintiffs allege that LNL and LNC breached the terms of policyholders’ contracts by increasing non-guaranteed cost of insurance rates beginning in 2017. Plaintiffs sought to represent classes of policyholders and sought damages on their behalf. On August 9, 2022, the court denied plaintiffs’ motion for class certification. The parties participated in a mediation on December 13, 2022, and subsequently reached a settlement. On January 26, 2023, the parties informed the presiding judge of a class settlement in this action, subject to final documentation and court approval. On March 24, 2023, plaintiffs filed a motion for preliminary approval of the class settlement. The provisional settlement, which is subject to both preliminary and final approval of the court, consists of $ 117.75 million in pre-tax cash (in the aggregate for both this litigation and the In re: Lincoln National COI Litigation matter discussed immediately above) and a five-year cost of insurance rate freeze, among other terms. TVPX ARS INC., as Securities Intermediary for Consolidated Wealth Management, LTD. v. The Lincoln National Life Insurance Company , filed in the U.S. District Court for the Eastern District of Pennsylvania, No. 2:18-cv-02989, is a putative class action that was filed on July 17, 2018. Plaintiff alleges that LNL charged more for non-guaranteed cost of insurance than permitted by the policy. Plaintiff seeks to represent all universal life and variable universal life policyholders who own policies issued by LNL or its predecessors containing non-guaranteed cost of insurance provisions that are similar to those of Plaintiff’s policy and seeks damages on behalf of all such policyholders. We are vigorously defending this matter. LSH Co. and Wells Fargo Bank, National Association, as securities intermediary for LSH Co. v. Lincoln National Corporation and The Lincoln National Life Insurance Company , pending in the U.S. District Court for the Eastern District of Pennsylvania, No. 2:18-cv-05529, is a civil action filed on December 21, 2018. Plaintiffs own universal life insurance policies originally issued by Jefferson-Pilot (now LNL). Plaintiffs allege that LNL breached the terms of policyholders’ contracts when it increased non-guaranteed cost of insurance rates in 2016 and 2017. We are vigorously defending this matter. Vida Longevity Fund, LP v. Lincoln Life & Annuity Company of New York , pending in the U.S. District Court for the Southern District of New York, No. 1:19-cv-06004, is a putative class action that was filed on June 27, 2019. Plaintiff alleges that LLANY charged more for non-guaranteed cost of insurance than was permitted by the policies. On March 31, 2022, the court issued an order granting plaintiff’s motion for class certification and certified a class of all current or former owners of six universal life insurance products issued by LLANY that were assessed a cost of insurance charge any time on or after June 27, 2013. Plaintiff seeks damages on behalf of the class. We are vigorously defending this matter. Angus v. The Lincoln National Life Insurance Company , pending in the U.S. District Court for the Eastern District of Pennsylvania, No. 2:22-cv-01878, is a putative class action filed on May 13, 2022. Plaintiff alleges that defendant LNL breached the terms of her life insurance policy by deducting non-guaranteed cost of insurance charges in excess of what is permitted by the policies. Plaintiff seeks to represent all owners of universal life insurance policies issued or insured by LNL or its predecessors containing non-guaranteed cost of insurance provisions that are similar to those of plaintiff’s policy and seeks damages on their behalf. Breach of contract is the only cause of action asserted. On August 26, 2022, LNL filed a motion to dismiss. We are vigorously defending this matter. Brighton Trustees, LLC, et al. v. The Lincoln National Life Insurance Company , pending in the U.S. District Court for the Northern District of Indiana, Fort Wayne Division, Case No. 1:23-cv-00171 (“ Brighton ”), is a civil action filed on April 20, 2023. Plaintiffs purport to own universal life insurance policies originally issued by Jefferson-Pilot (now LNL). Plaintiffs allege that LNL breached the terms of policyholders’ contracts and converted property when it increased non-guaranteed cost of insurance rates beginning in 2016. We are vigorously defending this matter. As we have previously disclosed, LNL and LNC reached a provisional class settlement agreement (the “Settlement”) with the plaintiffs in In re Lincoln National COI Litigation , pending in the U.S. District Court for the Eastern District of Pennsylvania, 2:16-cv-06605, and in In re Lincoln National 2017 COI Rate Litigation , pending in the U.S. District Court for the Eastern District of Pennsylvania, 2:17-cv-04150. The policies at issue in Brighton are “Class Policies” under the terms of the Settlement. A motion for preliminary approval of the Settlement was filed with the court on March 24, 2023, and remains pending. If the Settlement is approved by the court, the policies at issue in Brighton will not be “Final Settlement Class Policies” under the terms of the Settlement. Other Litigation Andrew Nitkewicz v. Lincoln Life & Annuity Company of New York, pending in the U.S. District Court for the Southern District of New York, No. 1:20-cv-06805, is a putative class action that was filed on August 24, 2020. Plaintiff Andrew Nitkewicz, as trustee of the Joan C. Lupe Trust, seeks to represent all current and former owners of universal life (including variable universal life) policies who own or owned policies issued by LLANY and its predecessors in interest that were in force at any time on or after June 27, 2013, and for which planned annual, semi-annual, or quarterly premiums were paid for any period beyond the end of the policy month of the insured’s death. Plaintiff alleges LLANY failed to refund unearned premium in violation of New York Insurance Law Section 3203(a)(2) in connection with the payment of death benefit claims for certain insurance policies. Plaintiff seeks compensatory damages and pre-judgment interest on behalf of the various classes and sub-class. On July 2, 2021, the court granted, with prejudice, LLANY’s November 2020 motion to dismiss this matter. Plaintiff filed a notice of appeal on July 28, 2021, and on September 26, 2022, the U.S. Court of Appeals for the Second Circuit reserved its decision and certified a question to the New York Court of Appeals. On October 20, 2022, the New York Court of Appeals accepted the question, and has set a briefing schedule. Henry Morgan et al. v. Lincoln National Corporation d/b/a Lincoln Financial Group, et al , filed in the District Court of the 14 th Judicial District of Dallas County, Texas, No. DC-23-02492, is a putative class action that was filed on February 22, 2023. Plaintiffs Henry Morgan, Susan Smith, Charles Smith, Laura Seale, Terri Cogburn, Laura Baesel, Kathleen Walton, Terry Warner, and Toni Hale (“Plaintiffs”) allege on behalf of a putative class that Lincoln National Corporation d/b/a Lincoln Financial Group, The Lincoln National Life Insurance Company and Lincoln Life & Annuity Company of New York (together, “Lincoln”), FMR, LLC, and Fidelity Product Services, LLC (“Fidelity”) created and marketed misleading and deceptive insurance products with attributes of investment products. The putative class comprises all individuals and entities who purchased Lincoln OptiBlend products that allocated account monies to the 1-Year Fidelity AIM Dividend Participation Account, between January 1, 2020, to December 31, 2022. Plaintiffs assert the following claims individually and on behalf of the class, (1) violations of the Texas Deceptive Trade Practices Act against Lincoln; (2) common-law fraud against Lincoln; (3) negligent misrepresentation against Lincoln and Fidelity; and (4) aiding and abetting fraud against Fidelity. Plaintiffs allege they suffered damages from “a missed investment return of approximately 5-6%” and mitigation damages. They seek actual, consequential and punitive damages, as well as pre-judgment and post-judgment interest, attorney’s fees, and litigation costs. On March 31, 2023, the Lincoln defendants filed a notice of removal removing the action from the 14 th Judicial District of Dallas County, Texas, to the United States District Court for the Northern District of Texas, Dallas Division. We are vigorously defending this matter.

Federal Income Taxes

Federal Income Taxes	3 Months Ended
	Mar. 31, 2023
Federal Income Taxes [Abstract]
Federal Income Taxes	17. Fed eral Income Taxes The effective tax rate is the ratio of tax expense (benefit) over pre-tax income (loss). The effective tax rate was 25 % and 14 % for the three months ended March 31, 2023 and 2022, respectively. The effective tax rate on pre-tax income is typically lower than the prevailing corporate federal income tax rate of 21 % due to benefits from preferential tax items including the separate accounts dividends-received deduction and tax credits. For the three months ended March 31, 2023, the effective tax rate differed from the prevailing corporate federal income tax rate due primarily to a tax benefit at 21 % from pre-tax losses in addition to the effects of preferential tax items. For the three months ended March 31, 2022, the effective tax rate differed from the prevailing corporate federal income tax rate due primarily to the effects of the preferential tax items.

Nature of Operations, Basis of Presentation and Summary of Significant Accounting Policies [Abstract]
Nature Of Operations	Nature of Operations The Lincoln National Life Insurance Company (“LNL” or the “Company,” which also may be referred to as “we,” “our” or “us”), a wholly-owned subsidiary of Lincoln National Corporation (“LNC” or the “Parent Company”), is domiciled in the state of Indiana. We own 100% of the outstanding common stock of one insurance company subsidiary, Lincoln Life & Annuity Company of New York (“LLANY”). We also own several non-insurance companies, including Lincoln Financial Distributors, our wholesale distributor, and Lincoln Financial Advisors Corporation, part of LNC’s retail distributor, Lincoln Financial Network. LNL is licensed and sells its products throughout the U.S. and several U.S. territories. Through our business segments, we sell a wide range of wealth protection, accumulation, group protection and retirement income products and solutions. These products primarily include universal life insurance (“UL”), variable universal life insurance (“VUL”), linked-benefit UL and VUL, indexed universal life insurance (“IUL”), term life insurance, fixed and indexed annuities, variable annuities, group life, disability and dental and employer-sponsored retirement plans and services. For more information on our segments and the products and solutions we provide, see Note 15.
Basis Of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements are prepared in accordance with United States of America generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions for the Securities and Exchange Commission (“SEC”) Quarterly Report on Form 10-Q, including Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. The information contained in the Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, as amended by Amendment No. 1 thereto (“2022 Form 10-K”), should be read in connection with the reading of these interim unaudited consolidated financial statements. Certain GAAP policies, which significantly affect the determination of financial condition, results of operations and cash flows, are summarized below. In the opinion of management, these statements include all normal recurring adjustments necessary for a fair presentation of the Company’s results. Operating results for the three months ended March 31, 2023, are not necessarily indicative of the results that may be expected for the full year ending December 31, 2023. All material inter-company accounts and transactions have been eliminated in consolidation. Certain amounts reported in prior periods’ consolidated financial statements have been reclassified to conform to the presentation adopted in the current period. We present disaggregated disclosures in the Notes below for long-duration insurance balances, applying the level of aggregation by reportable segment as follows: Reportable Segment Level of Aggregation Life Insurance Traditional Life UL and Other Annuities Variable Annuities Fixed Annuities Payout Annuities Group Protection Group Protection Retirement Plan Services Retirement Plan Services The fixed annuities level of aggregation represents deferred fixed annuities. We have excluded amounts reported in Other Operations from our disaggregated disclosures that are attributable to the indemnity reinsurance agreements with Protective Life Insurance Company (“Protective”) and Swiss Re Life & Health America, Inc (“Swiss Re”) as these contracts are fully reinsured, run-off institutional pension business in the form of group annuity and the results of certain disability income business and not reflected in the results of the reportable segments listed above.
Principles Of Consolidation	Principles of Consolidation The accompanying consolidated financial statements include the accounts of LNL and all other entities in which we have a controlling financial interest and any variable interest entities (“VIEs”) in which we are the primary beneficiary. We use the equity method of accounting to recognize all of our investments in limited liability partnerships. All material inter-company accounts and transactions have been eliminated in consolidation. Our involvement with VIEs is primarily to invest in assets that allow us to gain exposure to a broadly diversified portfolio of asset classes. A VIE is an entity that does not have sufficient equity to finance its own activities without additional financial support or where investors lack certain characteristics of a controlling financial interest. We assess our contractual, ownership or other interests in a VIE to determine if our interest participates in the variability the VIE was designed to absorb and pass onto variable interest holders. We perform an ongoing qualitative assessment of our variable interests in VIEs to determine whether we have a controlling financial interest and would therefore be considered the primary beneficiary of the VIE. If we determine we are the primary beneficiary of a VIE, we consolidate the assets and liabilities of the VIE in the consolidated financial statements.
Accounting Estimates and Assumptions	Accounting Estimates and Assumptions The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions affecting the reported amounts of assets and liabilities and the disclosures of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses for the reporting period. In applying these estimates and assumptions, management makes subjective and complex judgments that frequently require assumptions about matters that are uncertain and inherently subject to change, including matters related to or impacted by the COVID-19 pandemic. Actual results could differ from these estimates and assumptions. Included among the material (or potentially material) reported amounts and disclosures that require use of estimates are: fair value of certain financial assets, derivatives, allowances for credit losses, deferred acquisition costs (“DAC”), value of business acquired (“VOBA”), DSI, goodwill and other intangibles, market risk benefits (“MRBs”), future contract benefits, DFEL, pension plans, stock-based incentive compensation, income taxes including the recoverability of our deferred tax assets, and the potential effects of resolving litigated matters.
Business Combinations	Business Combinations We use the acquisition method of accounting for all business combination transactions, and accordingly, recognize the fair values of assets acquired, liabilities assumed and any noncontrolling interests in the consolidated financial statements. The allocation of fair values may be subject to adjustment after the initial allocation for up to a one-year period as more information becomes available relative to the fair values as of the acquisition date. The consolidated financial statements include the results of operations of any acquired company since the acquisition date.
Fair Value Measurement	Fair Value Measurement Our measurement of fair value is 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 non-performance risk, which would include our own credit risk. Our estimate of an exchange price is the price in an orderly transaction between market participants to sell the asset or transfer the liability (“exit price”) in the principal market, or the most advantageous market in the absence of a principal market, for that asset or liability, as opposed to the price that would be paid to acquire the asset or receive a liability (“entry price”). Pursuant to the Fair Value Measurements and Disclosures Topic of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification TM (“ASC”), we categorize our financial instruments carried at fair value into a three-level fair value hierarchy, based on the priority of inputs to the respective valuation technique. The three-level hierarchy for fair value measurement is defined as follows:  Level 1 – inputs to the valuation methodology are quoted prices available in active markets for identical investments as of the reporting date, except for large holdings subject to “blockage discounts” that are excluded;  Level 2 – inputs to the valuation methodology are other than quoted prices in active markets, which are either directly or indirectly observable as of the reporting date, and fair value can be determined through the use of models or other valuation methodologies; and  Level 3 – inputs to the valuation methodology are unobservable inputs in situations where there is little or no market activity for the asset or liability, and we make estimates and assumptions related to the pricing of the asset or liability, including assumptions regarding risk. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the investment. When a determination is made to classify an asset or liability within Level 3 of the fair value hierarchy, the determination is based upon the significance of the unobservable inputs to the overall fair value measurement. Because certain securities trade in less liquid or illiquid markets with limited or no pricing information, the determination of fair value for these securities is inherently more difficult. However, Level 3 fair value investments may include, in addition to the unobservable or Level 3 inputs, observable components, which are components that are actively quoted or can be validated to market-based sources.
Fixed Maturity Available-For-Sale Securities – Fair Valuation Methodologies and Associated Inputs	Fixed Maturity Available-For-Sale Securities – Fair Valuation Methodologies and Associated Inputs Securities classified as available-for-sale (“AFS”) consist of fixed maturity securities and are stated at fair value with unrealized gains and losses included within accumulated other comprehensive income (loss) (“AOCI”). We measure the fair value of our securities classified as fixed maturity AFS based on assumptions used by market participants in pricing the security. The most appropriate valuation methodology is selected based on the specific characteristics of the fixed maturity security, and we consistently apply the valuation methodology to measure the security’s fair value. Our fair value measurement is based on a market approach that utilizes prices and other relevant information generated by market transactions involving identical or comparable securities. Sources of inputs to the market approach primarily include third-party pricing services, independent broker quotations or pricing matrices. We do not adjust prices received from third parties; however, we do analyze the third-party pricing services’ valuation methodologies and related inputs and perform additional evaluation to determine the appropriate level within the fair value hierarchy. The observable and unobservable inputs to our valuation methodologies are based on a set of standard inputs that we generally use to evaluate all of our fixed maturity AFS securities. Observable inputs include benchmark yields, reported trades, broker-dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers and reference data. In addition, market indicators, industry and economic events are monitored, and further market data is acquired if certain triggers are met. For certain security types, additional inputs may be used, or some of the inputs described above may not be applicable. For private placement securities, we use pricing matrices that utilize observable pricing inputs of similar public securities and Treasury yields as inputs to the fair value measurement. Depending on the type of security or the daily market activity, standard inputs may be prioritized differently or may not be available for all fixed maturity AFS securities on any given day. For broker-quoted only securities, non-binding quotes from market makers or broker-dealers are obtained from sources recognized as market participants. For securities trading in less liquid or illiquid markets with limited or no pricing information, we use unobservable inputs to measure fair value. The following summarizes our fair valuation methodologies and associated inputs, which are particular to the specified security type and are in addition to the defined standard inputs to our valuation methodologies for all of our fixed maturity AFS securities discussed above:  Corporate bonds and U.S. government bonds – We also use Trade Reporting and Compliance Engine TM reported tables for our corporate bonds and vendor trading platform data for our U.S. government bonds.  Mortgage and asset-backed securities (“ABS”) – We also utilize additional inputs, which include new issues data, monthly payment information and monthly collateral performance, including prepayments, severity, delinquencies, step-down features and over collateralization features for each of our mortgage-backed securities (“MBS”), which include collateralized mortgage obligations and mortgage pass through securities backed by residential mortgages (“RMBS”), commercial mortgage-backed securities (“CMBS”) and collateralized loan obligations (“CLOs”).  State and municipal bonds – We also use additional inputs that include information from the Municipal Securities Rule Making Board, as well as material event notices, new issue data, issuer financial statements and Municipal Market Data benchmark yields for our state and municipal bonds.  Hybrid and redeemable preferred securities – We also utilize additional inputs of exchange prices (underlying and common stock of the same issuer) for our hybrid and redeemable preferred securities. In order to validate the pricing information and broker-dealer quotes, we employ, where possible, procedures that include comparisons with similar observable positions, comparisons with subsequent sales and observations of general market movements for those security classes. We have policies and procedures in place to review the process that is utilized by our third-party pricing service and the output that is provided to us by the pricing service. On a periodic basis, we test the pricing for a sample of securities to evaluate the inputs and assumptions used by the pricing service, and we perform a comparison of the pricing service output to an alternative pricing source. We also evaluate prices provided by our primary pricing service to ensure that they are not stale or unreasonable by reviewing the prices for unusual changes from period to period based on certain parameters or for lack of change from one period to the next.
Fixed Maturity AFS Securities – Evaluation for Recovery of Amortized Cost	Fixed Maturity AFS Securities – Evaluation for Recovery of Amortized Cost We regularly review our fixed maturity AFS securities (also referred to as “debt securities”) for declines in fair value that we determine to be impairment-related, including those attributable to credit risk factors that may require a credit loss allowance. For our debt securities, we generally consider the following to determine whether our debt securities with unrealized losses are credit impaired:  The estimated range and average period until recovery;  The estimated range and average holding period to maturity;  Remaining payment terms of the security;  Current delinquencies and nonperforming assets of underlying collateral;  Expected future default rates;  Collateral value by vintage, geographic region, industry concentration or property type;  Subordination levels or other credit enhancements as of the balance sheet date as compared to origination; and  Contractual and regulatory cash obligations. For a debt security, if we intend to sell a security, or it is more likely than not we will be required to sell a debt security before recovery of its amortized cost basis and the fair value of the debt security is below amortized cost, we conclude that an impairment has occurred and the amortized cost is written down to current fair value, with a corresponding charge to realized gain (loss) on the Consolidated Statements of Comprehensive Income (Loss). If we do not intend to sell a debt security, or it is not more likely than not we will be required to sell a debt security before recovery of its amortized cost basis but the present value of the cash flows expected to be collected is less than the amortized cost of the debt security (referred to as the credit loss), we conclude that an impairment has occurred, and a credit loss allowance is recorded, with a corresponding charge to realized gain (loss) on the Consolidated Statements of Comprehensive Income (Loss). The remainder of the decline to fair value related to factors other than credit loss is recorded in other comprehensive income (“OCI”) to unrealized losses on fixed maturity AFS securities on the Consolidated Statements of Stockholder’s Equity, as this amount is considered a noncredit impairment. When assessing our intent to sell a debt security, or if it is more likely than not we will be required to sell a debt security before recovery of its cost basis, we evaluate facts and circumstances such as, but not limited to, decisions to reposition our security portfolio, sales of securities to meet cash flow needs and sales of securities to capitalize on favorable pricing. Management considers the following as part of the evaluation:  The current economic environment and market conditions;  Our business strategy and current business plans;  The nature and type of security, including expected maturities and exposure to general credit, liquidity, market and interest rate risk;  Our analysis of data from financial models and other internal and industry sources to evaluate the current effectiveness of our hedging and overall risk management strategies;  The current and expected timing of contractual maturities of our assets and liabilities, expectations of prepayments on investments and expectations for surrenders and withdrawals of life insurance policies and annuity contracts;  The capital risk limits approved by management; and  Our current financial condition and liquidity demands. In order to determine the amount of the credit loss for a debt security, we calculate the recovery value by performing a discounted cash flow analysis based on the current cash flows and future cash flows we expect to recover. The discount rate is the effective interest rate implicit in the underlying debt security. The effective interest rate is the original yield, or the coupon if the debt security was previously impaired. See the discussion below for additional information on the methodology and significant inputs, by security type, that we use to determine the amount of a credit loss. To determine the recovery period of a debt security, we consider the facts and circumstances surrounding the underlying issuer including, but not limited to, the following:  Historical and implied volatility of the security;  The extent to which the fair value has been less than amortized cost;  Adverse conditions specifically related to the security or to specific conditions in an industry or geographic area;  Failure, if any, of the issuer of the security to make scheduled payments; and  Recoveries or additional declines in fair value subsequent to the balance sheet date. In periods subsequent to the recognition of a credit loss impairment through a credit loss allowance, we continue to reassess the expected cash flows of the debt security at each subsequent measurement date as necessary. If the measurement of credit loss changes, we recognize a provision for (or reversal of) credit loss expense through realized gain (loss) on the Consolidated Statements of Comprehensive Income (Loss), limited by the amount that amortized cost exceeds fair value. Losses are charged against the allowance for credit losses when management believes the uncollectibility of a debt security is confirmed or when either of the criteria regarding intent or requirement to sell is met. Accrued interest on debt securities is written-off when deemed uncollectible. To determine the recovery value of a corporate bond or CLO, we perform additional analysis related to the underlying issuer including, but not limited to, the following:  Fundamentals of the issuer to determine what we would recover if they were to file bankruptcy versus the price at which the market is trading;  Fundamentals of the industry in which the issuer operates;  Earnings multiples for the given industry or sector of an industry that the underlying issuer operates within, divided by the outstanding debt to determine an expected recovery value of the security in the case of a liquidation;  Expected cash flows of the issuer (e.g., whether the issuer has cash flows in excess of what is required to fund its operations);  Expectations regarding defaults and recovery rates;  Changes to the rating of the security by a rating agency; and  Additional market information (e.g., if there has been a replacement of the corporate debt security). Each quarter, we review the cash flows for the MBS portfolio, including current credit enhancements and trends in the underlying collateral performance to determine whether or not they are sufficient to provide for the recovery of our amortized cost. To determine recovery value of a MBS, we perform additional analysis related to the underlying issuer including, but not limited to, the following:  Discounted cash flow analysis based on the current cash flows and future cash flows we expect to recover;  Level of borrower creditworthiness of the home equity loans or residential mortgages that back an RMBS or commercial mortgages that back a CMBS;  Susceptibility to fair value fluctuations for changes in the interest rate environment;  Susceptibility to reinvestment risks, in cases where market yields are lower than the securities’ book yield earned;  Susceptibility to reinvestment risks, in cases where market yields are higher than the book yields earned on a security;  Expectations of sale of such a security where market yields are higher than the book yields earned on a security; and  Susceptibility to variability of prepayments. When evaluating MBS and mortgage-related ABS, we consider a number of pool-specific factors as well as market level factors when determining whether or not the impairment on the security requires a credit loss allowance. The most important factor is the performance of the underlying collateral in the security and the trends of that performance in the prior periods. We use this information about the collateral to forecast the timing and rate of mortgage loan defaults, including making projections for loans that are already delinquent and for those loans that are currently performing but may become delinquent in the future. Other factors used in this analysis include the credit characteristics of borrowers, geographic distribution of underlying loans and timing of liquidations by state. Once default rates and timing assumptions are determined, we then make assumptions regarding the severity of a default if it were to occur. Factors that impact the severity assumption include expectations for future home price appreciation or depreciation, loan size, first lien versus second lien, existence of loan level private mortgage insurance, type of occupancy and geographic distribution of loans. Once default and severity assumptions are determined for the security in question, cash flows for the underlying collateral are projected including expected defaults and prepayments. These cash flows on the collateral are then translated to cash flows on our tranche based on the cash flow waterfall of the entire capital security structure. If this analysis indicates the entire principal on a particular security will not be returned, the security is reviewed for a credit loss by comparing the expected cash flows to amortized cost. To the extent that the security has already been impaired through a credit loss allowance or was purchased at a discount, such that the amortized cost of the security is less than or equal to the present value of cash flows expected to be collected, no credit loss allowance is required. Otherwise, if the amortized cost of the security is greater than the present value of the cash flows expected to be collected, and the security was not purchased at a discount greater than the expected principal loss, then an impairment through a credit loss allowance is recognized. We further monitor the cash flows of all of our debt securities backed by mortgages on an ongoing basis. We also perform detailed analysis on all of our subprime, Alt-A, non-agency residential MBS and on a significant percentage of our debt securities backed by pools of commercial mortgages. The detailed analysis includes revising projected cash flows by updating the cash flows for actual cash received and applying assumptions with respect to expected defaults, foreclosures and recoveries in the future. These revised projected cash flows are then compared to the amount of credit enhancement (subordination) in the structure to determine whether the amortized cost of the security is recoverable. If it is not recoverable, we record an impairment through a credit loss allowance for the security.
Trading Securities	Trading Securities Trading securities consist of fixed maturity securities in designated portfolios, some of which support modified coinsurance and coinsurance with funds withheld reinsurance agreements. Investment results for the portfolios that support modified coinsurance and coinsurance with funds withheld reinsurance agreements, including gains and losses from sales, are passed directly to the reinsurers pursuant to contractual terms of the reinsurance agreements. Trading securities are carried at fair value, and changes in fair value and changes in the fair value of embedded derivative liabilities associated with the underlying reinsurance agreements are recorded in realized gain (loss) on the Consolidated Statements of Comprehensive Income (Loss) as they occur.
Equity Securities	Equity Securities Equity securities are carried at fair value, and changes in fair value are recorded in realized gain (loss) on the Consolidated Statements of Comprehensive Income (Loss) as they occur. Equity securities consist primarily of common stock of publicly-traded companies, privately placed securities and mutual fund shares. We measure the fair value of our equity securities based on assumptions used by market participants in pricing the security. The most appropriate valuation methodology is selected based on the specific characteristics of the equity security. Fair values of publicly-traded equity securities are determined using quoted prices in active markets for identical or comparable securities. When quoted prices are not available, we use valuation methodologies most appropriate for the specific asset. Fair values for private placement securities are determined using discounted cash flow, earnings multiple and other valuation models. The fair values of mutual fund shares that transact regularly are based on transaction prices of identical fund shares.
Mortgage Loans on Real Estate	Mortgage Loans on Real Estate Mortgage loans on real estate consist of commercial and residential mortgage loans and are generally carried at unpaid principal balances adjusted for amortization of premiums and accretion of discounts and are net of allowance for credit losses. We carry certain commercial mortgage loans associated with modified coinsurance agreements at fair value where the fair value option has been elected. Interest income is accrued on the principal balance of the loan based on the loan’s contractual interest rate. Premiums and discounts are amortized using the effective yield method over the life of the loan. Interest income and amortization of premiums and discounts are reported in net investment income on the Consolidated Statements of Comprehensive Income (Loss) along with mortgage loan fees, which are recorded as they are incurred. Our policy for commercial mortgage loans is to report loans that are 60 or more days past due, which equates to two or more payments missed, as delinquent. Our policy for residential mortgage loans is to report loans that are 90 or more days past due, which equates to three or more payments missed, as delinquent. We do not accrue interest on loans 90 days past due, and any interest received on these loans is either applied to the principal or recorded in net investment income on the Consolidated Statements of Comprehensive Income (Loss) when received, depending on the assessment of the collectability of the loan. We resume accruing interest once a loan complies with all of its original terms or restructured terms. Mortgage loans deemed uncollectible are charged against the allowance for credit losses, and subsequent recoveries, if any, are likewise credited to the allowance for credit losses. Accrued interest on mortgage loans is written-off when deemed uncollectible. In connection with our recognition of an allowance for credit losses for mortgage loans on real estate, we perform a quantitative analysis using a probability of default/loss given default/exposure at default approach to estimate expected credit losses in our mortgage loan portfolio as well as unfunded commitments related to commercial mortgage loans, exclusive of certain mortgage loans held at fair value. Our model estimates expected credit losses over the contractual terms of the loans, which are the periods over which we are exposed to credit risk, adjusted for expected prepayments. Credit loss estimates are segmented by commercial mortgage loans, residential mortgage loans, and unfunded commitments related to commercial mortgage loans. The allowance for credit losses for pooled loans of similar risk (i.e., commercial and residential mortgage loans) is estimated using relevant historical credit loss information adjusted for current conditions and reasonable and supportable forecasts of future conditions. Historical credit loss experience provides the basis for the estimation of expected credit losses with adjustments for differences in current loan-specific risk characteristics, such as differences in underwriting standards, portfolio mix, delinquency level, or term lengths as well as adjustments for changes in environmental conditions, such as unemployment rates, property values, or other factors that management deems relevant. We apply probability weights to the positive, base and adverse scenarios we use. For periods beyond our reasonable and supportable forecast, we use implicit mean reversion over the remaining life of the recoverable, meaning our model will inherently revert to the baseline scenario as the baseline is representative of the historical average over a longer period of time. Loans are considered impaired when it is probable that, based upon current information and events, we will be unable to collect all amounts due under the contractual terms of the loan agreement. When we determine that a loan is impaired, a specific credit loss allowance is established for the excess carrying value of the loan over its estimated value. The loan’s estimated value is based on: the present value of expected future cash flows discounted at the loan’s effective interest rate; the loan’s observable market price; or the fair value of the loan’s collateral. Allowance for credit losses are maintained at a level we believe is adequate to absorb current expected lifetime credit losses. Our periodic evaluation of the adequacy of the allowance for credit losses is based on historical loss experience, known and inherent risks in the portfolio, adverse situations that may affect the borrower’s ability to repay (including the timing of future payments), the estimated value of the underlying collateral, composition of the loan portfolio, current economic conditions, reasonable and supportable forecasts about the future and other relevant factors. Mortgage loans on real estate are presented net of the allowance for credit losses on the Consolidated Balance Sheets. Changes in the allowance are reported in realized gain (loss) on the Consolidated Statements of Comprehensive Income (Loss). Mortgage loans on real estate deemed uncollectible are charged against the allowance for credit losses, and subsequent recoveries, if any, are credited to the allowance for credit losses, limited to the aggregate of amounts previously charged-off and expected to be charged-off. Our commercial loan portfolio is primarily comprised of long-term loans secured by existing commercial real estate. We believe all of the commercial loans in our portfolio share three primary risks: borrower credit worthiness; sustainability of the cash flow of the property; and market risk; therefore, our methods of monitoring and assessing credit risk are consistent for our entire portfolio. For our commercial mortgage loan portfolio, trends in market vacancy and rental rates are incorporated into the analysis that we perform for monitored loans and may contribute to the establishment of (or an increase or decrease in) an allowance for credit losses. In addition, we review each loan individually in our commercial mortgage loan portfolio on an annual basis to identify emerging risks. We focus on properties that experienced a reduction in debt-service coverage or that have significant exposure to tenants with deteriorating credit profiles. Where warranted, we establish or increase a credit loss allowance for a specific loan based upon this analysis. We measure and assess the credit quality of our commercial mortgage loans by using loan-to-value and debt-service coverage ratios. The loan-to-value ratio compares the principal amount of the loan to the fair value at origination of the underlying property collateralizing the loan and is commonly expressed as a percentage. Loan-to-value ratios greater than 100 % indicate that the principal amount is greater than the collateral value. Therefore, all else being equal, a lower loan-to-value ratio generally indicates a higher quality loan. The debt-service coverage ratio compares a property’s net operating income to its debt-service payments. Debt-service coverage ratios of less than 1.0 indicate that property operations do not generate enough income to cover its current debt payments. Therefore, all else being equal, a higher debt-service coverage ratio generally indicates a higher quality loan. These credit quality metrics are monitored and reviewed at least annually. We have off-balance sheet commitments related to commercial mortgage loans. As such, an allowance for credit losses is developed based on the commercial mortgage loan process outlined above, along with an internally developed conversion factor. Our residential loan portfolio is primarily comprised of first lien mortgages secured by existing residential real estate. In contrast to the commercial mortgage loan portfolio, residential mortgage loans are primarily smaller-balance homogenous loans that share similar risk characteristics. Therefore, these pools of loans are collectively evaluated for inherent credit losses. Such evaluations consider numerous factors, including, but not limited to borrower credit scores, collateral values, loss forecasts, geographic location, delinquency rates and economic trends. These evaluations and assessments are revised as conditions change and new information becomes available, including updated forecasts, which can cause the allowance for credit losses to increase or decrease over time as such evaluations are revised. Generally, residential mortgage loan pools exclude loans that are nonperforming, as those loans are evaluated individually using the evaluation framework for specific allowance for credit losses described above. For residential mortgage loans, our primary credit quality indicator is whether the loan is performing or nonperforming. We generally define nonperforming residential mortgage loans as those that are 90 or more days past due and/or in nonaccrual status. There is generally a higher risk of experiencing credit losses when a residential mortgage loan is nonperforming. We monitor and update aging schedules and nonaccrual status on a monthly basis.
Policy Loans	Policy Loans Policy loans represent loans we issue to policyholders that use the cash surrender value of their life insurance policy as collateral. Policy loans are carried at unpaid principal balances.
Derivative Instruments	Derivative Instruments We hedge certain portions of our exposure to interest rate risk, foreign currency exchange risk, equity market risk and credit risk by entering into derivative transactions. Our derivative instruments are recognized as either assets or liabilities on the Consolidated Balance Sheets at estimated fair value. We have master netting agreements with each of our derivative counterparties that allow for the netting of our derivative asset and liability positions by counterparty. We categorize derivatives into a three-level hierarchy, based on the priority of the inputs to the respective valuation technique as discussed above in “Fair Value Measurement.” The accounting for changes in the estimated fair value of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship, and further, on the type of hedging relationship. For those derivative instruments that are designated and qualify as hedging instruments, we designate the hedging instrument based upon the exposure being hedged: as a cash flow hedge or a fair value hedge. For derivative instruments that are designated and qualify as a cash flow hedge, the effective portion of the gain or loss on the derivative instrument is reported as a component of AOCI and reclassified into net income in the same period or periods during which the hedged transaction affects net income. The remaining gain or loss on the derivative instrument in excess of the cumulative change in the present value of designated future cash flows of the hedged item (hedge ineffectiveness), if any, is recognized in net income during the period of change. For derivative instruments that are designated and qualify as a fair value hedge, the gain or loss on the derivative instrument, as well as the offsetting gain or loss on the hedged item attributable to the hedged risk are recognized in net income during the period of change in estimated fair values. For derivative instruments not designated as hedging instruments, but that are economic hedges, the gain or loss is recognized in net income. We purchase and issue financial instruments and products that contain embedded derivative instruments that are recorded with the associated host contract. When it is determined that the embedded derivative possesses economic characteristics that are not clearly and closely related to the economic characteristics of the host contract, and a separate instrument with the same terms would qualify as a derivative instrument, the embedded derivative is bifurcated from the host for measurement purposes and reported within other assets or other liabilities on the Consolidated Balance Sheets. The embedded derivative is carried at fair value with changes in fair value recognized in net income during the period of change. We employ several different methods for determining the fair value of our derivative instruments. The fair value of our derivative contracts are measured based on current settlement values, which are based on quoted market prices, industry standard models that are commercially available and broker quotes. These techniques project cash flows of the derivatives using current and implied future market conditions. We calculate the present value of the cash flows to measure the current fair market value of the derivative.
Other Investments	Other Investments Other investments consist primarily of alternative investments, cash collateral receivables related to our derivative instruments, Federal Home Loan Bank (“FHLB”) common stock and short-term investments. Alternative investments consist primarily of investments in limited partnerships (“LPs”). We account for our investments in LPs using the equity method to determine the carrying value. Recognition of alternative investment income is delayed due to the availability of the related financial statements, which are generally obtained from the partnerships’ general partners. As a result, our private equity investments are generally on a three-month delay and our hedge funds are on a one-month delay. In addition, the impact of audit adjustments related to completion of calendar-year financial statement audits of the investees are typically received during the second quarter of each calendar year. Accordingly, our investment income from alternative investments for any calendar-year period may not include the complete impact of the change in the underlying net assets for the partnership for that calendar-year period. In uncleared derivative transactions, we and the counterparty enter into a credit support annex requiring either party to post collateral, which may be in the form of cash, equal to the net derivative exposure. Cash collateral we have posted to a counterparty is recorded within other investments. Cash collateral a counterparty has posted is recorded within payables for collateral on investments. We also have investments in FHLB common stock, carried at cost, that enable access to the FHLB lending program. For more information on our collateralized financing arrangements, see “Payables for Collateral on Investments” below. Short-term investments consist of securities with original maturities of one year or less, but greater than three months. Securities included in short-term investments are carried at fair value, with valuation methods and inputs consistent with those applied to fixed maturity AFS securities.
Cash and Invested Cash	Cash and Invested Cash Cash and invested cash is carried at cost and includes all highly liquid debt instruments purchased with an original maturity of three months or less.
DAC, VOBA, DSI and DFEL	DAC, VOBA, DSI and DFEL Acquisition costs directly related to successful contract acquisitions or renewals of UL, VUL, traditional life insurance, group life and disability insurance, annuities and other investment contracts have been deferred (i.e., DAC). Such acquisition costs are capitalized in the period they are incurred and primarily include commissions, certain bonuses, portion of total compensation and benefits of certain employees involved in the acquisition process and medical and inspection fees. VOBA is an intangible asset that reflects the estimated fair value of in-force contracts in a life insurance company acquisition and represents the portion of the purchase price that is allocated to the value of the right to receive future cash flows from the business in force at the acquisition date. Bonus credits and excess interest for dollar cost averaging contracts are considered DSI and reported in deferred acquisition costs, value of business acquired and deferred sales inducements on the Consolidated Balance Sheets. Contract sales charges that are collected in the early years of an insurance contract are deferred and reported as deferred front-end loads (i.e., DFEL) on the Consolidated Balance Sheets. DAC, VOBA, DSI and DFEL amortization is reported within the following financial statement line items on the Consolidated Statements of Comprehensive Income (Loss):  DAC and VOBA – commissions and other expenses  DSI – interest credited  DFEL – fee income DAC, VOBA, DSI and DFEL are amortized on a constant level basis relative to the insurance in force over the expected term of the related contracts using the groupings and actuarial assumptions that are consistent with those used for calculating the related policyholder liability balances. Actuarial assumptions include, but are not limited to, mortality, morbidity and certain policyholder behaviors such as persistency, which are adjusted for emerging experience and expected trends of the related long-duration insurance contracts and certain investment contracts by each reportable segment. During the third quarter of each year, we conduct our comprehensive review and update these actuarial assumptions. We may update our actuarial assumptions in other quarters as we become aware of information that warrants updating outside of our comprehensive review. These resulting changes are applied prospectively. The following provides a summary of our DAC, VOBA, DSI and DFEL amortization basis and expected amortization period by reportable segment: Reportable Segment Amortization Basis Expected Amortization Period Life Insurance Policy count of policies in force On average 60 years Annuities Total deposits paid to date on policies in force Between 30 to 40 years Group Protection Group certificate contracts in force 4 years Retirement Plan Services Lives in force Between 40 to 50 years We account for modifications of insurance contracts that result in a substantially unchanged contract as a continuation of the replaced contract. We account for modifications of insurance contracts that result in a substantially changed contract as an extinguishment of the replaced contract. For reinsurance transactions where we receive proceeds that represent recovery of our previously incurred acquisition costs, we reduce the applicable unamortized acquisition cost such that net acquisition costs are capitalized and charged to commissions and other expenses.
Reinsurance	Reinsurance We and LLANY enter into reinsurance agreements in the normal course of business to limit our exposure to the risk of loss and to enhance our capital management. In order for a reinsurance agreement to qualify for reinsurance accounting, the agreement must satisfy certain risk transfer conditions that include, among other items, a reasonable possibility of a significant loss for the assuming entity. When we apply reinsurance accounting, premiums, benefits and DAC amortization are reported net of reinsurance ceded, as applicable, on the Consolidated Statements of Comprehensive Income (Loss). Amounts currently recoverable, such as ceded reserves, other than ceded MRBs, are reported in reinsurance recoverables, and amounts currently payable to the reinsurers, such as premiums, are included in other liabilities on the Consolidated Balance Sheets. We use deposit accounting to recognize reinsurance agreements that do not transfer significant insurance risk. This accounting treatment results in amounts paid or received by us to be considered on deposit with the reinsurer and such amounts are reported in other assets and other liabilities, respectively, on the Consolidated Balance Sheets. As amounts are paid or received, consistent with the underlying contracts, deposit assets or liabilities are adjusted. When there is a contractual right of offset, assets and liabilities and revenues and expenses from certain reinsurance contracts that grant statutory surplus relief to our insurance companies are netted on the Consolidated Balance Sheets and Consolidated Statements of Comprehensive Income (Loss), respectively. Reinsurance recoverables are measured and recognized consistent with the liabilities related to the underlying contracts. The interest assumption used for discounting reinsurance recoverables associated with non-participating traditional life insurance contracts and limited payment life-contingent annuity contracts is the upper-medium grade fixed income instrument (“single-A”) interest rate locked-in at the reinsurance contract issuance date. We remeasure reinsurance recoverables associated with non-participating traditional life insurance contracts and limited payment life-contingent annuity contracts with the current single-A interest rate as of the end of each reporting period. Ceded MRBs are accounted for separately from reinsurance recoverables. See “MRBs” below for additional information. The cost of reinsurance related to long-duration contracts is accounted for over the life of the underlying reinsured policies using assumptions consistent with those used to account for the underlying policies and is reported within other assets on the Consolidated Balance Sheets. We estimated an allowance for credit losses for all reinsurance recoverables and related reinsurance deposit assets held by our subsidiaries, other than ceded MRB assets. As such, we performed a quantitative analysis using a probability of loss model approach to estimate expected credit losses for reinsurance recoverables, inclusive of similar assets recognized using the deposit method of accounting. The credit loss allowance is a general allowance for pools of receivables with similar risk characteristics segmented by credit risk ratings and receivables assessed on an individual basis that do not share similar risk characteristics where we anticipate a credit loss over the life of reinsurance-related assets, other than ceded MRB assets. Our model uses relevant internal or external historical loss information adjusted for current conditions and reasonable and supportable forecasts of future events and conditions in developing our credit loss estimate. We utilized historical credit rating data to form an estimation of probability of default of counterparties by means of a transition matrix that provides the rates of credit migration for credit ratings transitioning to impairment. We updated reinsurer credit ratings during the period to incorporate the most up-to-date information on the current state of the financial stability of our reinsurers. To simulate changes in economic conditions, we used positive, base and adverse scenarios that include varying levels of loss given default assumptions to reflect the impact of changes in severity of losses. We applied probability weights to the positive, base and adverse scenarios. For periods beyond our reasonable and supportable forecasts, we used implicit mean reversion over the remaining life of the recoverable. Additionally, we considered factors that impact our exposure at default that are driven by actuarial expectations around term assumptions rather than being directly driven by market or economic environment. Our model estimates the expected credit losses over the life of the reinsurance asset. Credit loss estimates are segmented based on counterparty credit risk. Our modeling process utilizes counterparty credit ratings, collateral types and amounts, and term and run-off assumptions. For reinsurance recoverables that do not share similar risk characteristics, we assessed on an individual basis to determine a specific credit loss allowance. We estimated expected credit losses over the contractual term of the recoverable, which is the period during which we are exposed to the credit risk. Reinsurance recoverables may not have explicit contractual lives, but are tied to the underlying insurance products; as a result, we estimated the contractual life by utilizing actuarial estimates of the timing of payouts related to those underlying products. Reinsurance agreements often require the reinsurer to collateralize the recoverable with funds in a trust account or with a letter of credit for the benefit of the ceding insurance entity that can reduce the expected credit losses on a given agreement. As such, we review reinsurance collateral by individual agreement to sensitize risk of loss based on level of collateralization. This review is driven by the assumption that non-collateralized reinsurance recoverables would have materially higher losses in times of default. Therefore, reinsurance recoverables are pooled as either fully-collateralized or non-collateralized. Reinsurance recoverables are presented net of the allowance for credit losses on the Consolidated Balance Sheets. Changes in the allowance for credit losses are reported in realized gain (loss) on the Consolidated Statements of Comprehensive Income (Loss). Reinsurance recoverables deemed uncollectible are charged against the allowance for credit losses, and subsequent recoveries, if any, are credited to the allowance for credit losses, limited to the aggregate of amounts previously charged-off and expected to be charged-off. In the first quarter of 2023, the reinsurance arrangement with LNBAR for certain variable annuity guaranteed benefit riders was modified from a coinsurance funds withheld arrangement to a modified coinsurance arrangement.
Goodwill	Goodwill We recognize the excess of the purchase price, plus the fair value of any noncontrolling interest in the acquiree, over the fair value of identifiable net assets acquired as goodwill. Goodwill is not amortized, but is reviewed for impairment annually as of October 1 and more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. We perform a quantitative goodwill impairment test where the fair value of the reporting unit is determined and compared to the carrying value of the reporting unit. If the carrying value of the reporting unit is greater than the reporting unit’s fair value, goodwill is impaired and written down to the reporting unit’s fair value; and a charge is reported in impairment of intangibles on the Consolidated Statements of Comprehensive Income (Loss). The results of one goodwill impairment test on one reporting unit cannot subsidize the results of another reporting unit.
Other Assets and Other Liabilities	Other Assets and Other Liabilities Other assets consist primarily of certain reinsurance assets, net of allowance for credit losses, ceded MRB liabilities, specifically identifiable intangible assets, current taxes and deferred taxes, premiums and fees receivable, property and equipment, balances associated with corporate-owned and bank-owned life insurance, receivables resulting from sales of securities that had not yet settled as of the balance sheet date, operating lease right-of-use (“ROU”) assets, finance lease assets and other receivables and prepaid expenses. Other liabilities consist primarily of certain reinsurance payables, deferred taxes, other policyholder liabilities, pension and other employee benefit liabilities, deferred gain on business sold through reinsurance, derivative instrument liabilities, payables resulting from purchases of securities that had not yet settled as of the balance sheet date, long-term operating lease liabilities, certain financing arrangements, finance lease liabilities, ceded MRB assets and other accrued expenses. The carrying values of specifically identifiable intangible assets are reviewed at least annually for indicators of impairment in value that are related to credit loss or non-credit, including unexpected or adverse changes in the following: the economic or competitive environments in which the company operates; profitability analyses; cash flow analyses; and the fair value of the relevant business operation. If there was an indication of impairment, then the discounted cash flow method would be used to measure the impairment, and the carrying value would be adjusted as necessary and reported in impairment of intangibles on the Consolidated Statements of Comprehensive Income (Loss). Sales force intangibles are attributable to the value of the new business distribution system acquired through business combinations. These assets are amortized on a straight-line basis over their useful life of 25 years. Specifically identifiable intangible assets also includes the value of customer relationships acquired (“VOCRA”) and value of distribution agreements (“VODA”). The carrying values of VOCRA and VODA are amortized using a straight-line basis over their weighted average life of 20 years and 13 years, respectively. Property and equipment owned for company use is carried at cost less allowances for depreciation. Provisions for depreciation of investment real estate and property and equipment owned for company use are computed principally on the straight-line method over the estimated useful lives of the assets, which include buildings, computer hardware and software and other property and equipment. Certain assets on the Consolidated Balance Sheets are related to finance leases and certain financing arrangements and are depreciated in a manner consistent with our current depreciation policy for owned assets. We periodically review the carrying value of our long-lived assets, including property and equipment, for impairment whenever events or circumstances indicate that the carrying amount of such assets may not be fully recoverable. For long-lived assets to be held and used, impairments are recognized when the carrying amount of a long-lived asset is not recoverable and exceeds its fair value. The carrying amount of a long-lived asset is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. An impairment loss is measured as the amount by which the carrying amount of a long-lived asset exceeds its fair value. Long-lived assets to be disposed of by abandonment or in an exchange for a similar productive long-lived asset are classified as held-for-use until they are disposed. Long-lived assets to be sold are classified as held-for-sale and are no longer depreciated. Certain criteria have to be met in order for the long-lived asset to be classified as held-for-sale, including that a sale is probable and expected to occur within one year. Long-lived assets classified as held-for-sale are recorded at the lower of their carrying amount or fair value less cost to sell. We lease office space and certain equipment under various long-term lease agreements. We determine if an arrangement is a lease at inception. Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at the commencement date. Our leases do not provide an implicit rate; therefore, we use our incremental borrowing rate at the commencement date in determining the present value of future payments. The ROU asset is calculated using the lease liability carrying amount, plus or minus prepaid/accrued lease payments, minus the unamortized balance of lease incentives received, plus unamortized initial direct costs. Lease terms used to calculate our lease obligation include options when we are reasonably certain that we will exercise such options. Our lease agreements may contain both lease and non-lease components, which are accounted for separately. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. Other assets includes deferred losses on business sold through reinsurance attributable to our 2012 and 2014 reinsurance transactions where we ceded closed blocks of UL contracts with secondary guarantees to Lincoln National Reinsurance Company (Barbados) Limited (“LNBAR”), a wholly-owned subsidiary of LNC. We are recognizing the losses related to these transactions over a period of 30 years. Other liabilities includes deferred gains on business sold through reinsurance. During 2009, we completed a reinsurance transaction whereby we assumed a closed block of term contracts from First Penn-Pacific Life Insurance Company, a wholly-owned subsidiary of LNC. We are recognizing the gain related to this transaction over a period of 15 years. During 2012, we completed a reinsurance transaction whereby we ceded a closed block of UL contracts with secondary guarantees to LNBAR. We are recognizing the gain related to the transaction over a period of 30 years. During 2013, we completed a reinsurance transaction whereby we ceded a closed block of UL contracts with secondary guarantees to LNBAR. During 2019, we amended the 2013 reinsurance transaction by recapturing the underlying base policy from LNBAR while continuing to cede the associated riders. We are recognizing the gain related to this transaction over the expected life of the underlying business, or 20 years. Effective October 1, 2018, we entered into a reinsurance agreement with Athene Holding Ltd. (“Athene”). We are recognizing the gain related to this transaction over the period in which the majority of account values is expected to run off, or 20 years. Effective October 1, 2021, we entered into a reinsurance agreement with Security Life of Denver Insurance Company (a subsidiary of Resolution Life that we refer to herein as “Resolution Life”). We are recognizing the gain related to this transaction over the projected life of the policies, or 30 years.
Separate Account Assets and Liabilities	Separate Account Assets and Liabilities Separate accounts represent segregated funds that are maintained to meet specific investment objectives of policyholders who direct the investments and bear the investment risk, except to the extent of minimum guarantees made by the Company with respect to certain accounts. The assets of each account are legally segregated and are not subject to claims that arise out of any other business of the Company. We report separate account assets as a summary total on the Consolidated Balance Sheets based on the fair value of the underlying investments. The underlying investments consist primarily of mutual funds, fixed maturity AFS securities, short-term investments and cash. Investment income and net realized and unrealized gains (losses) of the separate accounts generally accrue directly to the policyholders; therefore, they are not reflected on the Consolidated Statements of Comprehensive Income (Loss), and the Consolidated Statements of Cash Flows do not reflect investment activity of the separate accounts. Asset-based fees and contract administration charges (collectively referred to as “policyholder assessments”) are assessed against the accounts and included within fee income on the Consolidated Statements of Comprehensive Income (Loss). An amount equivalent to the separate account assets is recorded as separate account liabilities, representing the account balance obligated to be returned to the policyholder.
Future Contract Benefits	Future Contract Benefits Future contract benefits represent liability reserves, including liability for future policy benefits (“LFPB”), liability for future claims reserves and additional liability for other insurance benefits that we have established and carry based on estimates of how much we will need to pay for future benefits and claims. The LFPB associated with non-participating traditional life insurance contracts and limited payment life-contingent annuity contracts is measured using a net premium ratio approach. This approach accrues expected benefits and claims in proportion to the premium revenue recognized. For life-contingent payout annuity contracts with limited premium payments, as premium collection is not the completion of the earnings process, gross premiums in excess of net premiums are deferred. This excess of gross premiums received over the related net premiums is referred to as the deferred profit liability (“DPL”). The DPL is included in the LFPB, and profits are recognized over the life of the contracts. In measuring our LFPB, we establish cohorts, which are groupings of long-duration contracts. Factors that we consider in determining cohorts include, but are not limited to, our contract classification and issue year requirements, product risk characteristics, assumptions and modeling level used in the valuation systems. The net premium ratio is capped at 100 % at the individual cohort level. Expected benefits and claims in excess of premium revenue recognized are expensed immediately. We use actuarial assumptions to best estimate future premium and benefit cash flows (“cash flow assumptions”) as well as the actual historical cash flows received and paid to derive a net premium ratio in measuring the LFPB. These actuarial assumptions include mortality rates, morbidity, policyholder behavior (e.g., persistency) and withdrawals based principally on generally accepted actuarial methods and assumptions. During the third quarter of each year, we conduct our comprehensive review of the cash flow assumptions and projection models used in estimating these liabilities and update these assumptions (excluding the claims settlement expense assumption that is locked in at inception) in the calculation of the net premium ratio. We may also update these assumptions in other quarters as we become aware of information that is indicative of such update. On a quarterly basis, we retrospectively update the net premium ratio for actual experience. The remeasurement of LFPB for both assumption updates and actual experience are reported within policyholder liability remeasurement gain (loss) on the Consolidated Statements of Comprehensive Income (Loss). For all contract cohorts issued after January 1, 2021, interest is accrued on LFPB at the single-A interest rate on the contract cohort inception date. For contract cohorts issued prior to January 1, 2021, interest remains accruing at the original discount rate in effect on the contract cohort inception date due to the modified retrospective transition method. We also remeasure the LFPB using the single-A interest rate as of the end of each reporting period, which is reported within policyholder liability discount rate remeasurement gain (loss) on the Consolidated Statements of Comprehensive Income (Loss). We evaluate the liability for future claims on our long-term life and disability group products. Given the term and renewal features of our product and funding nature of the associated premiums, we have determined that the liability value is generally zero for policies that are not on claim. Therefore, the liability for future claims represents future payments on claims for which a disability event has occurred as of the valuation date. In measuring the liability for future claims, we establish cohorts similar to the process described above and use actuarial assumptions primarily based on claim termination rates, offsets for other insurance including social security and long-term disability incidence and severity assumptions. Cash flow assumptions are subject to the comprehensive review process discussed above. On a quarterly basis, the liability for future claims is updated for actual claims experience. The remeasurement of the liability for future claims for both assumption updates and actual experience are reported within policyholder liability remeasurement gain (loss) on the Consolidated Statements of Comprehensive Income (Loss). We remeasure the liability for future claims using a single-A interest rate as of the end of each reporting period, which is reported within policyholder liability discount rate remeasurement gain (loss) on the Consolidated Statements of Comprehensive Income (Loss). We use the single-A interest rate curve to discount cash flows used to calculate the LFPB and the liability for future claims. This curve is developed using the upper-medium grade (low credit risk) fixed-income instrument yields that are intended to reflect the duration characteristics of the applicable insurance liabilities. We issue UL contracts with separate accounts that may include various types of guaranteed benefits that are not accounted for as MRBs or embedded derivatives. These guaranteed benefits require an additional liability that is calculated by estimating the present value of total expected benefit payments over the life of the contract from inception divided by the present value of total expected assessments over the life of the contract (“benefit ratio”) multiplied by the cumulative assessments recorded from the contract inception through the balance sheet date less the cumulative payments plus interest on the liability. Cash flow assumptions incorporated in a benefit ratio in measuring these additional liabilities for other insurance benefits include mortality rates, morbidity, policyholder behavior (e.g., persistency) and withdrawals based principally on generally accepted actuarial methods and assumptions. During the third quarter of each year, we conduct our comprehensive review of the cash flow assumptions and projection models used in estimating these liabilities and update these assumptions in the calculation of the benefit ratio. We may also update these assumptions in other quarters as we become aware of information that is indicative of such update. On a quarterly basis, we retrospectively update the benefit ratio for actual experience. The remeasurement of additional liability for both assumptions and actual experience are reported within policyholder liability remeasurement gain (loss) on the Consolidated Statements of Comprehensive Income (Loss). As future cash flow assumption and experience updates result in changes in expected benefit payments or assessments, the benefit ratio is recalculated using the updated expected benefit payments and assessments over the life of the contract since inception. The revised benefit ratio is then applied to the liability calculation described above. Premium deficiency testing is performed for interest-sensitive life products periodically using best estimate assumptions as of the testing date to test the adequacy and appropriateness of the established net reserve (i.e., GAAP reserves net of any DSI or VOBA assets). The premium deficiency test is also performed using a discount rate based on the average crediting rate. A premium deficiency exists when the net reserve plus the present value of expected future gross premiums are determined to be insufficient to cover expected future benefits and non-level expenses. The business written or assumed by us includes participating life insurance contracts, under which the policyholder is entitled to share in the earnings of such contracts via receipt of dividends. The dividend scale for participating policies is reviewed annually and may be adjusted to reflect recent experience and future expectations.
MRBs	MRBs MRBs are contracts or contract features that provide protection to the policyholder from other-than-nominal capital market risk and expose us to other-than-nominal capital market risk upon the occurrence of a specific event or circumstance, such as death, annuitization or periodic withdrawal. MRBs do not include the death benefit component of a life insurance contract (i.e., the difference between the account balance and the death benefit amount). All long-duration insurance contracts and certain investment contracts are subject to MRB evaluation. An MRB can be in either an asset or a liability position. Our MRB assets and MRB liabilities are reported at fair value separately on the Consolidated Balance Sheets. We issue variable and fixed annuity contracts that may include various types of guaranteed living benefit (“GLB”) and guaranteed death benefit (“GDB”) riders that we have classified as MRBs. For contracts that contain multiple features that qualify as MRBs, the MRBs are valued on a combined basis using an integrated model. We have entered into reinsurance agreements to cede certain GLB and GDB riders where the reinsurance agreements themselves are accounted for as MRBs or contain MRBs. We therefore record ceded MRB assets and ceded MRB liabilities associated with these reinsurance agreements. Ceded MRB liabilities are included in other assets and ceded MRB assets are included in other liabilities on the Consolidated Balance Sheets. MRBs are valued based on a stochastic projection of risk neutral scenarios that incorporate a spread reflecting our non-performance risk. Ceded MRBs are valued based on a stochastic projection of risk neutral scenarios that incorporate a spread reflecting our counterparties’ non-performance risk. The scenario assumptions, at each valuation date, are those we view to be appropriate for a hypothetical market participant and include assumptions for capital markets, policyholder behavior (e.g., policy lapse, rider utilization, etc.) mortality, risk margin and administrative expenses. These assumptions are based on a combination of historical data and actuarial judgments. During the third quarter of each year, we conduct our comprehensive review of the actuarial assumptions and projection models used in estimating these MRBs and update these assumptions on a prospective basis as needed. We may also update these assumptions in other quarters as we become aware of information that is indicative of the need for such an update. The assumptions for our own non-performance risk and our counterparties’ non-performance risk for MRBs and ceded MRBs, respectively, are determined at each valuation date and reflect our and our counterparties’ risks of not fulfilling the obligations of the underlying liability. The spread for the non-performance risk is added to the discount rates used in determining the fair value from the net cash flows. For information on fair value inputs, see Note 12.
Policyholder Account Balances	Policyholder Account Balance s Policyholder account balances include the contract value that has accrued to the benefit of the policyholder as of the balance sheet date. The liability for policyholder account balances includes UL and VUL and investment-type annuity products where account balances are equal to deposits plus interest credited less withdrawals, surrender charges, policyholder assessments, as well as amounts representing the fair value of embedded derivative instruments associated with our IUL and indexed annuity products. During the third quarter of each year, we conduct our comprehensive review of the assumptions and projection models used in estimating these embedded derivatives and update assumptions as needed. We may also update these assumptions in other quarters as we become aware of information that is indicative of the need for such an update.
Short-Term and Long-Term Debt	Short-Term and Long-Term Debt Short-term debt has contractual or expected maturities of one year or less. Long-term debt has contractual or expected maturities greater than one year.
Payables for Collateral on Investments	Payables for Collateral on Investments When we enter into collateralized financing transactions on our investments, a liability is recorded equal to the cash or non-cash collateral received. This liability is included within payables for collateral on investments on the Consolidated Balance Sheets. Income and expenses associated with these transactions are recorded as investment income and investment expenses within net investment income on the Consolidated Statements of Comprehensive Income (Loss). Changes in payables for collateral on investments are reflected within cash flows from investing activities on the Consolidated Statements of Cash Flows.
Contingencies and Commitments	Contingencies and Commitments 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. Contingencies arising from environmental remediation costs, regulatory judgments, claims, assessments, guarantees, litigation, recourse reserves, fines, penalties and other sources are recorded when deemed probable and reasonably estimable, based on our best estimate.
Fee Income	Fee Income Fee income for investment and interest-sensitive life insurance contracts consists of asset-based fees, percent of premium charges, contract administration charges and surrender charges that are assessed against policyholder account balances. Investment products consist primarily of individual and group variable and fixed annuities. Interest-sensitive life insurance products include UL, VUL, linked-benefit UL and VUL and other interest-sensitive life insurance policies. These products include life insurance sold to individuals, corporate-owned life insurance and bank-owned life insurance. The timing of revenue recognition as it relates to fees assessed on investment contracts is determined based on the nature of such fees. Asset-based fees and contract administration charges are assessed on a daily or monthly basis and recognized as revenue as performance obligations are met, over the period underlying customer assets are owned or advisory services are provided. Percent of premium charges are assessed at the time of premium payment and recognized as revenue when assessed and earned. Certain amounts assessed that represent compensation for services to be provided in future periods are reported as unearned revenue and recognized in income over the periods benefited. Surrender charges are recognized upon surrender of a contract by the policyholder in accordance with contractual terms. For investment and interest-sensitive life insurance contracts, the amounts collected from policyholders are considered deposits and are not included in revenue. Wholesaling-related 12b-1 fees received from separate account fund sponsors as compensation for servicing the underlying mutual funds are recorded as revenues based on a contractual percentage of the market value of mutual fund assets over the period shares are owned by customers. Net investment advisory fees related to asset management of certain separate account funds are recorded as revenues based on a contractual percentage of the customer’s managed assets over the period advisory services are provided.
Insurance Premiums	Insurance Premiums Insurance premiums consist primarily of group insurance products, traditional life insurance and payout annuities with life contingencies. These insurance premiums are recognized as revenue when due.
Net Investment Income	Net Investment Income We earn investment income on the underlying general account investments supporting our fixed products less related expenses. Dividends and interest income, recorded in net investment income, are recognized when earned. Amortization of premiums and accretion of discounts on investments in debt securities are reflected in net investment income over the contractual terms of the investments in a manner that produces a constant effective yield. For CLOs and MBS, included in the trading and fixed maturity AFS securities portfolios, we recognize income using a constant effective yield based on anticipated prepayments and the estimated economic life of the securities. When actual prepayments differ significantly from originally anticipated prepayments, the retrospective effective yield is recalculated to reflect actual payments to date and a catch up adjustment is recorded in the current period. In addition, the new effective yield, which reflects anticipated future payments, is used prospectively. Any adjustments resulting from changes in effective yield are reflected in net investment income on the Consolidated Statements of Comprehensive Income (Loss).
Realized Gain (Loss)	Realized Gain (Loss) Realized gain (loss) includes realized gains and losses from the sale of investments, write-downs for impairments of investments and changes in the allowance for credit losses for financial assets, changes in fair value of mortgage loans on real estate accounted for under the fair value option, changes in fair value of equity securities, certain derivative and embedded derivative gains and losses, gains and losses on the sale of subsidiaries and businesses and net gains and losses on reinsurance-related embedded derivatives and trading securities. Realized gains and losses on the sale of investments are determined using the specific identification method. Realized gain (loss) is reported net of allocations of investment gains and losses to certain policyholders, certain funds withheld on reinsurance arrangements and certain modified coinsurance arrangements for which we have a contractual obligation.
MRB Gain (Loss)	MRB Gain (Loss) MRB gain (loss) includes the change in fair value of MRB and ceded MRB assets and liabilities. Changes in the fair value of MRB assets and liabilities are recognized in net income (loss), except for the portion attributable to the change in non-performance risk that is recognized in OCI. Changes in the fair value of ceded MRB assets and liabilities, including the changes in our counterparties’ non-performance risks, are recognized in net income (loss).
Other Revenues	Other Revenues Other revenues consist primarily of fees attributable to broker-dealer services recorded as performance obligations are met, either at the time of sale or over time based on a contractual percentage of customer account values, and proceeds from reinsurance recaptures. The broker-dealer services primarily relate to our retail sales network and consist of commission revenue for the sale of non-affiliated securities recorded on a trade date basis and advisory fee income. Advisory fee income is asset-based revenues recorded as earned based on a contractual percentage of customer account values. Other revenues earned by our Group Protection segment consist of fees from administrative services performed, which are recognized as performance obligations are met over the terms of the underlying agreements.
Interest Credited	Interest Credited We credit interest to our policyholder account balances based on the contractual terms supporting our products.
Benefits	Benefits Benefits for UL and other interest-sensitive life insurance products include benefit claims incurred during the period in excess of contract account balances. Benefits also include the change in reserves for life insurance products with secondary guarantee benefits, annuity products with guaranteed death and living benefits and certain annuities with life contingencies. For traditional life, group life and disability income products, benefits are recognized when incurred in a manner consistent with the related premium recognition policies.
Policyholder Liability Remeasurement Gain (Loss)	Policyholder Liability Remeasurement Gain (Loss) Policyholder liability remeasurement gain (loss) recognized in net income (loss) includes remeasurement gains and losses resulting from updates in cash flow assumptions and actual variance from expected experience used in the net premium ratio or benefit ratio calculation for future policy benefits associated with traditional life insurance and limited payment life-contingent annuity products, liabilities for future claims associated with our group products, and additional liabilities for other insurance benefits on certain guaranteed benefits associated with our UL products. Policyholder liability remeasurement gain (loss) recognized in OCI includes any changes resulting from the discount rate remeasurement of future policy benefits associated with traditional life insurance and limited payment life-contingent annuity products and liabilities for future claims associated with our group products as of each reporting period.
Spark Program Expense	Spark Program Expense Spark program expense consists primarily of costs related to our Spark Initiative.
Pension and Other Postretirement Benefit Plans	Pension and Other Postretirement Benefit Plans Pursuant to the accounting rules for our obligations to employees and agents under our various pension and other postretirement benefit plans, we are required to make a number of assumptions to estimate related liabilities and expenses. The mortality assumption is based on actual and anticipated plan experience, determined using acceptable actuarial methods. We use assumptions for the weighted-average discount rate and expected return on plan assets to estimate pension expense. The discount rate assumptions are determined using an analysis of current market information and the projected benefit flows associated with these plans. The expected long-term rate of return on plan assets is based on historical and projected future rates of return on the funds invested in the plan. The calculation of our accumulated postretirement benefit obligation also uses an assumption of weighted-average annual rate of increase in the per capita cost of covered benefits, which reflects a health care cost trend rate.
Stock-Based Compensation	Stock-Based Compensation In general, we expense the fair value of stock awards included in our incentive compensation plans. As of the date LNC’s Board of Directors approves stock awards, the fair value of stock options is determined using a Black-Scholes options valuation methodology, and the fair value of other stock awards is based upon the market value of the stock. The fair value of the awards is expensed over the performance or service period, which generally corresponds to the vesting period, and is recognized as an increase to common stock in stockholder’s equity. We apply an estimated forfeiture rate to our accrual of compensation cost. We classify certain stock awards as liabilities. For these awards, the settlement value is classified as a liability on the Consolidated Balance Sheets, and the liability is marked-to-market through net income at the end of each reporting period. Stock-based compensation expense is reflected in commissions and other expenses on the Consolidated Statements of Comprehensive Income (Loss).
Interest and Debt Expense	Interest and Debt Expense Interest expense on our short-term and long-term debt is recognized as due and any associated premiums, discounts and debt issuance costs are amortized (accreted) over the term of the related borrowing utilizing the effective interest method. In addition, gains or losses related to certain derivative instruments associated with debt are recognized in interest and debt expense during the period of the change.
Income Taxes	Income Taxes LNC files a U.S. consolidated income tax return that includes us and LNC’s other eligible subsidiaries. Ineligible subsidiaries file separate individual corporate tax returns. Deferred income taxes are recognized, based on enacted rates, when assets and liabilities have different values for financial statement and tax reporting purposes. A valuation allowance is recorded to the extent required. 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, we consider many factors, including: the nature and character of the deferred tax assets and liabilities; taxable income in prior carryback years; future reversals of temporary differences; the length of time carryovers can be utilized; and any tax planning strategies we would employ to avoid a tax benefit from expiring unused.

(2) The liquidity/duration adjustment input represents an estimated market participant composite of adjustments attributable to liquidity premiums, expected durations, structures and credit quality that would be applied to the market observable information of an investment. (3) The lapse input represents the estimated probability of a contract surrendering during a year, and thereby forgoing any future benefits. The range for indexed annuity contracts represents the lapses during the surrender charge period. (4) The utilization of GLB withdrawals input represents the estimated percentage of policyholders that utilize the GLB withdrawal riders. (5) The utilization factors are applied to the present value of claims or premiums, as appropriate, in the MRB calculation to estimate the impact of inefficient GLB withdrawal behavior, including taking less than or more than the maximum GLB withdrawal. (6) The non-performance risk input represents the estimated additional credit spread that market participants would apply to the market observable discount rate when pricing a contract. The non-performance risk input was weighted by the absolute value of the sensitivity of the reserve to the non-performance risk assumption. The non-performance risk input for LPR ceded derivative was weighted using a simple average. (7) The mortality input represents the estimated probability of when an individual belonging to a particular group, categorized according to age or some other factor such as gender, will die. (8) The volatility input represents overall volatilities assumed for the underlying variable annuity funds, which include a mixture of equity and fixed-income assets. Volatility assumptions vary by fund due to the benchmarking of different indices. The volatility input was weighted by the relative account value assigned to each index. (9) The mortality is based on a combination of company and industry experience, adjusted for improvement factors. (10) A weighted average input range is not a meaningful measurement for lapse, utilization factors or mortality.
