Nature of Operations and Basis of Presentation [Abstract]
Nature of Operations and Basis of Presentation	1. Nature of Operations and Basis of Presentation 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 two insurance company subsidiaries, Lincoln Life & Annuity Company of New York (“LLANY”) and Lincoln Life Assurance Company of Boston (“LLACB”). Effective October 1, 2021, LLACB was merged into LNL. 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. Through our business segments, we sell a wide range of wealth protection, accumulation, retirement income and group protection products and solutions. These products primarily include fixed and indexed annuities, variable annuities, universal life insurance (“UL”), variable universal life insurance (“VUL”), linked-benefit UL and VUL, indexed universal life insurance (“IUL”), term life insurance, employer-sponsored retirement plans and services, and group life, disability and dental. LNL is licensed and sells its products throughout the U.S. and several U.S. territories. See Note 15 for additional information. 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, 2020 (“2020 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 in our 2020 Form 10-K. 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 nine months ended September 30, 2021, are not necessarily indicative of the results that may be expected for the full year ending December 31, 2021, especially when considering the risks and uncertainties associated with the COVID-19 pandemic and the future impacts of the pandemic on our business, results of operations and financial condition. All material inter-company accounts and transactions have been eliminated in consolidation.

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 Financial Accounting Standards Board (“FASB”) and the impact of the adoption on our consolidated financial statements. ASUs not listed below were assessed and determined to be either not applicable or insignificant in presentation or amount. StandardDescriptionEffective DateEffect on Financial Statements or Other Significant MattersASU 2020-04, Reference Rate Reform (Topic 848) and related amendmentsThe 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, 2022, with certain exceptions. The amendments are effective for contract modifications made between March 12, 2020, and December 31, 2022. March 12, 2020 through December 31, 2022This standard may be elected and applied prospectively as reference rate reform unfolds. We have elected practical expedients to maintain hedge accounting for certain derivatives. We will continue to evaluate our options under this guidance as our reference rate reform adoption process continues. 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 amendmentsThese amendments make changes to the accounting and reporting for long-duration contracts issued by an insurance entity that will significantly change how insurers account for long-duration contracts, including how they measure, recognize and make disclosures about insurance liabilities and deferred acquisition costs. Under this ASU, insurers will be required to review cash flow assumptions at least annually and update them if necessary. They also will have to make quarterly updates to the discount rate assumptions they use to measure the liability for future policyholder benefits. The ASU creates a new category of market risk benefits (i.e., features that protect the contract holder from capital market risk and expose the insurer to that risk) that insurers will have to measure at fair value. The ASU provides various transition methods by topic that entities may elect upon adoption. The ASU is currently effective January 1, 2023, and early adoption is permitted. January 1, 2023We are currently evaluating the impact of adopting this ASU on our consolidated financial condition and results of operations.

Variable Interest Entities

Variable Interest Entities [Abstract]
Variable Interest Entities	‎ 3. Variable Interest 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 4. Limited Partnerships and Limited Liability Companies We invest in certain limited partnerships (“LPs”) and limited liability companies (“LLCs”), including qualified affordable housing projects, 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 $2.7 billion and $2.1 billion as of September 30, 2021, and December 31, 2020, respectively. Included in these carrying amounts are our investments in qualified affordable housing projects, which were $5 million and $7 million as of September 30, 2021, and December 31, 2020, respectively. We received affordable housing tax credits of less than $1 million and $1 million for the three months ended September 30, 2021 and 2020, respectively, and $1 million and $4 million for the nine months ended September 30, 2021 and 2020, respectively. These returns were recognized in federal income tax expense (benefit) on our Consolidated Statements of Comprehensive Income (Loss).

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 September 30, 2021 Gross Number Fair Unrealized of Value Losses Securities (1)Less than six months$ 9 $ 2 4 Six months or greater, but less than nine months 17 5 1 Twelve months or greater 60 9 25 Total$ 86 $ 16 30 As of December 31, 2020 Gross Number Fair Unrealized of Value Losses Securities (1)Less than six months$ 63 $ 23 14 Six months or greater, but less than nine months 2 1 4 Nine months or greater, but less than twelve months 22 6 13 Twelve months or greater 30 11 20 Total$ 117 $ 41 51 (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 increased by $188 million for the nine months ended September 30, 2021. As discussed further below, we believe the unrealized loss position as of September 30, 2021, 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 September 30, 2021, 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 September 30, 2021, 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 widening credit spreads and rising interest rates 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 September 30, 2021, and December 31, 2020, 96% of the fair value of our corporate bond portfolio was rated investment grade. As of September 30, 2021, and December 31, 2020, the portion of our corporate bond portfolio rated below investment grade had an amortized cost of $3.6 billion and $3.8 billion, respectively, and a fair value of $3.8 billion and $4.0 billion, respectively. Based upon the analysis discussed above, we believe that as of September 30, 2021, and December 31, 2020, we would have recovered the amortized cost of each corporate bond. As of September 30, 2021, the unrealized losses associated with our mortgage-backed securities and ABS were attributable primarily to widening credit spreads and rising interest rates 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 September 30, 2021, 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 September 30, 2021 Corporate Bonds RMBS ABS Total Balance as of beginning-of-period$ 8 $ 1 $ - $ 9 Additions for securities for which credit losses were not previously recognized 8 - - 8 Additions from purchases of PCD debt securities (1) - - - - Balance as of end-of-period (2)$ 16 $ 1 $ - $ 17 For the Nine Months Ended September 30, 2021 Corporate Bonds RMBS ABS Total Balance as of beginning-of-period$ 12 $ 1 $ - $ 13 Additions for securities for which credit losses were not previously recognized 8 - - 8 Additions from purchases of PCD debt securities (1) - - - - Additions (reductions) for securities for which credit losses were previously recognized 2 - - 2 Reductions for securities charged-off (6) - - (6)Balance as of end-of-period (2)$ 16 $ 1 $ - $ 17 For the Three Months Ended September 30, 2020 Corporate Bonds RMBS ABS Total Balance as of beginning-of-period$ 19 $ 1 $ 1 $ 21 Additions for securities for which credit losses were not previously recognized 5 - - 5 Additions from purchases of PCD debt securities (1) - - - - Additions (reductions) for securities for which credit losses were previously recognized (3) - (1) (4)Reductions for securities charged-off (10) - - (10)Balance as of end-of-period (2)$ 11 $ 1 $ - $ 12 For the Nine Months Ended September 30, 2020 Corporate Bonds RMBS ABS Total Balance as of beginning-of-period$ - $ - $ - $ - Additions for securities for which credit losses were not previously recognized 39 1 1 41 Additions from purchases of PCD debt securities (1) - - - - Additions (reductions) for securities for which credit losses were previously recognized (3) - (1) (4)Reductions for securities disposed (15) - - (15)Reductions for securities charged-off (10) - - (10)Balance as of end-of-period (2)$ 11 $ 1 $ - $ 12 (1)Represents purchased credit-deteriorated (“PCD”) fixed maturity AFS securities.(2)Accrued interest receivable on fixed maturity AFS securities totaled $1.0 billion as of September 30, 2021 and 2020, and was excluded from the estimate of credit losses.

Derivative Instruments [Abstract]
Derivative Instruments	5. 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 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 14 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 designated and qualifying as cash flow hedges to hedge our exposure to interest rate fluctuations related to the forecasted purchases of certain assets. We also use forward-starting interest rate swaps to hedge the interest rate exposure within our life products related to the forecasted purchases of certain assets. 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 products and indexed variable annuity 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. Contract holders 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 contract holders, 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 products. Put options are contracts that require counterparties to pay us 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. 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 contract holders and investors. The CDSs hedge the contract holders 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 Lincoln National Reinsurance Company (Barbados) Limited (“LNBAR”), an affiliated insurer, assumes the risk under certain UL contracts for lapse protection riders (“LPR”). If the contract holder’s account value is insufficient to pay the cost of insurance charges required to keep the policy in force, and the contract holder has made the required deposits, we will be reimbursed for those charges. Embedded Derivatives We have embedded derivatives that include: GLB Reserves Embedded Derivatives Certain features of these guarantees have elements of both insurance benefits accounted for under the Financial Services – Insurance – Claim Costs and Liabilities for Future Policy Benefits Subtopic of the FASB Accounting Standards Codification (“ASC”) (“benefit reserves”) and embedded derivatives accounted for under the Derivatives and Hedging and the Fair Value Measurements and Disclosures Topics of the FASB ASC (“embedded derivative reserves”). We calculate the value of the benefit reserves and the embedded derivative reserves based on the specific characteristics of each guaranteed living benefit (“GLB”) feature. We use a hedging strategy designed to mitigate the risk and income statement volatility caused by changes in the equity markets, interest rates and volatility associated with GLBs offered in our variable annuity products, including products with guaranteed withdrawal benefit and guaranteed income benefit features. These GLB features are reinsured among various reinsurance counterparties on a coinsurance basis. We cede a portion of the GLB features to LNBAR, a wholly-owned subsidiary of LNC, on a funds withheld coinsurance basis. The funds withheld arrangement includes a dynamic hedging strategy designed to mitigate selected risks. Changes in the value of the hedge contracts due to changes in equity markets, interest rates and implied volatilities hedge the income statement effect of changes in embedded derivative GLB reserves assumed by LNBAR caused by those same factors. We rebalance our hedge positions based upon changes in these factors as needed. While we actively manage our hedge positions, these hedge positions may not be totally effective in offsetting changes in the embedded derivative reserve assumed by LNBAR due to, among other things, differences in timing between when a market exposure changes and corresponding changes to the hedge positions, extreme swings in the equity markets and interest rates, market volatility, contract holder behavior, divergence between the performance of the underlying funds and the hedging indices, divergence between the actual and expected performance of the hedge instruments and our ability to purchase hedging instruments at prices consistent with our desired risk and return trade-off. However, the hedging results do not impact LNL due to a funds withheld agreement with LNBAR, which causes the financial impact of the derivatives, as well as the cash flow activity, to be reflected on LNBAR. 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. Contract holders 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 contract holders, 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 (“Modco”) and coinsurance with funds withheld reinsurance agreements with embedded derivatives related to the withheld assets of the related funds.

This reclassification would be due primarily to interest rate variances related to our interest rate swap agreements. For the nine months ended September 30, 2021 and 2020, 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 September 30, 2021, we did not have any exposure related to CDSs for which we are the seller.‎ Information related to our CDSs for which we are the seller (dollars in millions) was as follows: As of December 31, 2020 Credit Reason Nature Rating of Number Maximum for of Underlyingof Fair PotentialCredit Contract Type Maturity Entering Recourse Obligation (1) Instruments Value (2) PayoutBasket CDSs 12/20/2025 (3) (4) BBB+ 1 $ 1 $ 51 (1)Represents average credit ratings based on the midpoint of the applicable ratings among Moody’s, S&P and Fitch Ratings, as scaled to the corresponding S&P ratings.(2)Broker quotes are used to determine the market value of our CDSs.(3)CDSs were entered into in order to hedge the liability exposure on certain variable annuity products.(4)Sellers do not have the right to demand indemnification or compensation from third parties in case of a loss (payment) on the contract.

If these netting agreements were not in place, we would have been required to post collateral if the market value was less than zero. 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 (“NPR”). The NPR 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 September 30, 2021, the NPR 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 not have any exposure as of September 30, 2021, or December 31, 2020. ‎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 September 30, 2021 As of December 31, 2020 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- $ 1,940 $ - $ 1,232 $ (7)A+ 2,527 (40) 1,112 (175)A 60 - 53 - A- 421 - 572 - $ 4,948 $ (40)$ 2,969 $ (182) Balance Sheet Offsetting Information related to the effects of offsetting (in millions) was as follows: As of September 30, 2021 Embedded DerivativeDerivative InstrumentsInstruments Total Financial Assets Gross amount of recognized assets $ 7,393 $ 2,248 $ 9,641 Gross amounts offset (1,914) - (1,914)Net amount of assets (1) 5,479 2,248 7,727 Gross amounts not offset: Cash collateral (4,948) - (4,948)Non-cash collateral (224) - (224)Net amount $ 307 $ 2,248 $ 2,555 Financial Liabilities Gross amount of recognized liabilities $ 663 $ 7,245 $ 7,908 Gross amounts offset (3) - (3)Net amount of liabilities 660 7,245 7,905 Gross amounts not offset: Cash collateral (40) - (40)Non-cash collateral - - - Net amount $ 620 $ 7,245 $ 7,865  (1)Includes deferred premiums of $651 million reported in other assets on our Consolidated Balance Sheets.

Federal Income Taxes [Abstract]
Federal Income Taxes	6. Federal Income Taxes The effective tax rate is the ratio of tax expense (benefit) over pre-tax income (loss). The effective tax rate was 15% and 16% for the three and nine months ended September 30, 2021, respectively, compared to 29% and 137%, respectively, for the corresponding periods in 2020. 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 and nine months ended September 30, 2021, the effective tax rate differed from the prevailing corporate federal income tax rate of 21% due primarily to the effects of the preferential tax items. For the three and nine months ended September 30, 2020, the effective tax rate differed from the prevailing corporate federal income tax rate of 21% due primarily to a tax benefit at 21% from pre-tax losses in addition to the effects of preferential tax items.

Reinsurance [Abstract]
Reinsurance	7. Reinsurance Credit Losses on Reinsurance-related Assets In connection with our recognition of an allowance for credit losses for reinsurance-related assets, we perform a quantitative analysis using a probability of loss approach to estimate expected credit losses for reinsurance recoverables, inclusive of similar assets recognized using the deposit method of accounting. As of September 30, 2021, our allowance for credit losses for reinsurance-related assets was $196 million. There have been no material changes to the allowance for credit losses for the nine months ended September 30, 2021.  Modco Agreements Some portions of our annuity business have been reinsured on a Modco basis with other companies. In a Modco agreement, we as the ceding company retain the reserves, as well as the assets backing those reserves, and the reinsurer shares proportionally in all financial terms of the reinsured policies based on their respective percentage of the risk. Effective October 1, 2018, we entered into one such Modco agreement with Athene Holding Ltd. (“Athene”) to reinsure fixed annuity products, which resulted in a deposit asset of $5.1 billion and $5.8 billion as of September 30, 2021, and December 31, 2020, respectively, within other assets on our Consolidated Balance Sheets. We held assets in support of reserves associated with the transaction in a Modco investment portfolio, which consisted of the following (in millions): As ofAs of September 30,December 31, 20212020 Fixed maturity AFS securities $ 1,114 $ 1,531 Trading securities 3,096 3,357 Equity securities 27 17 Mortgage loans on real estate 792 832 Derivative investments 86 103 Other investments 251 167 Cash and invested cash 207 92 Accrued investment income 36 42 Other assets 25 3 Total $ 5,634 $ 6,144 In addition, the portfolio was supported by $166 million of over-collateralization and a $152 million letter of credit as of September 30, 2021. Reinsurance Transaction Our previously announced reinsurance transaction with Security Life of Denver Insurance Company, a subsidiary of Resolution Life, to reinsure liabilities under a block of in-force executive benefit and universal life policies in our Life Insurance business became effective as of October 1, 2021. The agreement is structured as coinsurance for the general account reserves and Modco for the separate account reserves. The $1.2 billion in proceeds from the transaction will predominantly be used by LNC to fund incremental share repurchases that we expect to be completed by the end of the first quarter of 2022, with the remainder to be used for general corporate purposes, primarily paying down debt.

The determination of GDB liabilities is based on models that involve a range of scenarios and assumptions, including those regarding expected market rates of return and volatility, contract surrender rates and mortality experience. The following summarizes the balances of and changes in the liabilities for GDBs (in millions), which were recorded in future contract benefits on our Consolidated Balance Sheets: For the Nine Months Ended September 30, 2021 2020 Balance as of beginning-of-year$ 121 $ 117 Changes in reserves 31 46 Benefits paid (16) (21) Balance as of end-of-period$ 136 $ 142 Variable Annuity Contracts Account balances of variable annuity contracts, including those with guarantees, (in millions) were invested in separate account investment options as follows: As ofAs of September 30,December 31, 2021 2020 Asset Type Domestic equity $ 73,503 $ 70,362 International equity 21,041 20,855 Fixed income 44,627 43,521 Total $ 139,171 $ 134,738 Percent of total variable annuity separate account values 98% 98% Secondary Guarantee Products Future contract benefits and other contract holder funds include reserves for our secondary guarantee products sold through our Life Insurance segment. Reserves on UL and VUL products with secondary guarantees represented 37% of total life insurance in-force reserves as of September 30, 2021, and December 31, 2020. UL and VUL products with secondary guarantees represented 17% and 15% of total life insurance sales for the three and nine months ended September 30, 2021, respectively, compared to 32% for the corresponding periods in 2020.

Liability For Unpaid Claims [Abstract]
Liability For Unpaid Claims	9. Liability for Unpaid Claims The liability for unpaid claims consists primarily of long-term disability claims and is reported in future contract benefits on our Consolidated Balance Sheets. Changes in the liability for unpaid claims (in millions) were as follows: For the Nine Months Ended September 30, 2021 2020 Balance as of beginning-of-year$ 5,934 $ 5,552 Reinsurance recoverable 151 152 Net balance as of beginning-of-year 5,783 5,400 Incurred related to: Current year 2,999 2,615 Prior years: Interest 112 116 All other incurred (1) (284) (157)Total incurred 2,827 2,574 Paid related to: Current year (1,393) (1,184)Prior years (1,222) (1,118)Total paid (2,615) (2,302)Net balance as of end-of-period 5,995 5,672 Reinsurance recoverable 145 149 Balance as of end-of-period$ 6,140 $ 5,821 (1)All other incurred is primarily impacted by the level of claim resolutions in the period compared to that which is expected by the reserve assumption. A negative number implies a favorable result where claim resolutions were more favorable than assumed. Our claim resolution rate assumption used in determining reserves is our expectation of the resolution rate we will experience over the long-term life of the block of claims. It will vary from actual experience in any one period, both favorably and unfavorably. The interest rate assumption used for discounting long-term claim reserves is an important part of the reserving process due to the long benefit period for these claims. Interest accrued on prior years’ reserves has been calculated on the opening reserve balance less one-half of the prior years’ incurred claim payments at our average reserve discount rate. Long-term disability benefits may extend for many years, and claim development schedules do not reflect these longer benefit periods. As a result, we use longer term retrospective runoff studies, experience studies and prospective studies to develop our liability estimates.

Debt [Abstract]
Debt	10. Debt Credit Facility On June 21, 2021, LNC entered into an amended and restated credit agreement with a syndicate of banks, which amended and restated LNC’s existing credit facility agreement, dated as of July 31, 2019. The amended credit facility, which is unsecured, allows for the issuance of letters of credit (“LOCs”) and borrowing of up to $2.5 billion and has a commitment termination date of June 19, 2026. The LOCs under the credit facility are used primarily to satisfy reserve credit requirements of (i) LNL and LNC’s other domestic insurance companies for which reserve credit is provided by our captive reinsurance subsidiaries and LNBAR and (ii) certain ceding companies of our legacy reinsurance business.‎ The amended credit facility agreement contains: Customary terms and conditions, including covenants restricting the ability of LNC and its subsidiaries to incur liens and the ability of LNC to merge or consolidate with another entity where it is not the surviving entity and dispose of all or substantially all of its assets;Financial covenants including maintenance by LNC of a minimum consolidated net worth equal to the sum of $10.0 billion plus 50% of the aggregate net proceeds of equity issuances received by LNC or any of its subsidiaries in accordance with the terms of the agreement; and a debt-to-capital ratio as defined in accordance with the agreement not to exceed 0.35 to 1.00;A cap on LNC’s secured non-operating indebtedness and non-operating indebtedness of LNC’s subsidiaries equal to 7.5% of total capitalization, as defined in accordance with the agreement; andCustomary events of default, subject to certain materiality thresholds and grace periods for certain of those events of default. Upon an event of default, the amended credit facility agreement provides that, among other things, the commitments may be terminated and the loans then outstanding may be declared due and payable. As of September 30, 2021, LNC was in compliance with all such covenants.

Contingencies and Commitments [Abstract]
Contingencies and Commitments	11.  Contingencies and Commitments Contingencies 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 September 30, 2021. 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 September 30, 2021, 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 $120 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 several of these matters. Although a loss is believed to be reasonably possible for 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 our consolidated financial statements, but, based on information currently known, management does not believe those cases are likely to have such an impact. 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 will initiate arbitration proceedings, as necessary, under these agreements in order to protect our contractual rights. Additionally, reinsurers have initiated, and may in the future initiate, arbitration proceedings against us. We believe it is unlikely the outcome of these disputes would have a material impact on our consolidated financial statements. For more information about reinsurance, see Note 7. 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. Hanks v. Lincoln Life & Annuity Company of New York (“LLANY”) and Voya Retirement Insurance and Annuity Company (“Voya”), filed in the U.S. District Court for the Southern District of New York, No. 1:16-cv-6399, is a putative class action that was served on LLANY on August 12, 2016. Plaintiff owns a universal life policy originally issued by Aetna (now Voya) and alleges that (i) Voya breached the terms of the policy when it increased non-guaranteed cost of insurance rates on Plaintiff’s policy; and (ii) LLANY, as reinsurer and administrator of Plaintiff’s policy, engaged in wrongful conduct related to the cost of insurance increase and was unjustly enriched as a result. Plaintiff seeks to represent all owners of Aetna life insurance policies that were subject to non-guaranteed cost of insurance rate increases in 2016 and seeks damages on their behalf. On March 13, 2019, the court issued an order granting plaintiff’s motion for class certification for the breach of contract claim and denying such motion with respect to the unjust enrichment claim against LLANY, and, on September 12, 2019, the court issued an order approving the parties’ joint stipulation of dismissal with respect to the unjust enrichment claim and dismissed LLANY as a defendant in the case. In light of LLANY’s role as reinsurer and administrator under the 1998 coinsurance agreement with Aetna (now Voya), and of the parties’ rights and obligations thereunder, LLANY continues to be actively engaged in the defense of this case. On September 30, 2020, the court denied plaintiff’s motion for summary judgment and granted in part Voya’s motion for summary judgment. On October 22, 2021, the parties informed the presiding judge that they have reached a settlement of the action, subject to court approval. The parties requested the suspension of the current case-schedule, including trial date, and 45 days to prepare a final settlement agreement and motion for preliminary approval. On October 25, 2021, the presiding judge approved the parties’ request. The terms of the provisional settlement remain confidential. EFG Bank AG, Cayman Branch, et al. v.

Valuation Methodologies and Associated Inputs for Financial Instruments Not Carried at Fair Value The following discussion outlines the methodologies and assumptions used to determine the fair value of our financial instruments not carried at fair value on our Consolidated Balance Sheets. 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 Federal Home Loan Bank (“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. Other Contract Holder Funds Other contract holder funds include remaining guaranteed interest and similar contracts and account values of certain investment 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 September 30, 2021, and December 31, 2020, the remaining guaranteed interest and similar contracts carrying value approximated fair value. The fair value of the account values 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 our other contract holder funds 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 our 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 Modco 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 our 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 as a result of a change to a third-party pricing source during 2020, mortgage loans electing the fair value option were categorized as Level 3 as of September 30, 2021, and December 31, 2020. 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 September 30, December 31, 2021 2020 Fair value$ 792 $ 832 Aggregate contractual principal 795 839 As of September 30, 2021, and December 31, 2020, no loans for which the fair value option was elected were in non-accrual status, and none were more than 90 days past due and still accruing interest. Financial Instruments Carried at Fair Value Short-Term Investments Short-term investments consist of securities with original maturities of one year or less, but greater than three months, and are included in other investments on our Consolidated Balance Sheets. 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. We did not have any assets or liabilities measured at fair value on a nonrecurring basis as of September 30, 2021, or December 31, 2020.

For the three and nine months ended September 30, 2021 and 2020, transfers in and out of Level 3 were attributable primarily to the financial instruments’ observable market information no longer being available or becoming available. During the second and third quarters of 2021, transfers into and out of Level 3 included free-standing and embedded derivative instruments for which we changed valuation techniques. This change in valuation technique was primarily from unobservable inputs in counterparty models to a mathematical model provided by a third party. The updated valuation technique is considered industry standard and provides us with greater visibility into the economic valuation inputs. The following summarizes the fair value (in millions), valuation techniques and significant unobservable inputs of the Level 3 fair value measurements as of September 30, 2021: Weighted Average Fair Valuation Significant Assumption or Input Value Technique Unobservable Inputs Input Ranges Range (1)Assets Investments: Fixed maturity AFS and trading securities: Corporate bonds$ 3,594 Discounted cash flow Liquidity/duration adjustment (2) 0.0% -6.8% 1.4% Foreign government bonds 106 Discounted cash flow Liquidity/duration adjustment (2) 1.0% -8.8% 3.5% ABS 19 Discounted cash flow Liquidity/duration adjustment (2) 2.2% -2.2% 2.2% Hybrid and redeemable preferred securities 7 Discounted cash flow Liquidity/duration adjustment (2) 1.7% -1.7% 1.7% Equity securities 21 Discounted cash flow Liquidity/duration adjustment (2) 4.5% -6.6% 6.1% Other assets: GLB direct and ceded embedded derivatives 1,753 Discounted cash flow Long-term lapse rate (3) 1% -30% (10) Utilization of guaranteed withdrawals (4)85% -100% 94% Claims utilization factor (5) 60% -100% (10) Premiums utilization factor (5) 80% -115% (10) NPR (6) 0.08% -1.37% 0.93% Mortality rate (7) (9) (10) Volatility (8) 1% -28% 14.55% Indexed annuity ceded embedded derivatives 495 Discounted cash flow Lapse rate (3) 0% -9% (10) Mortality rate (7) (9) (10) LPR ceded derivative 293 Discounted cash flow Long-term lapse rate (3) 0% -1.65% (10) NPR (6) 0.08% -1.37% 0.9% Mortality rate (7) (9) (10) Liabilities Future contract benefits – indexed annuity contracts embedded derivatives$ (4,758)Discounted cash flow Lapse rate (3) 0% -9% (10) Mortality rate (7) (9) (10) Other liabilities – GLB ceded embedded derivatives (1,749)Discounted cash flow Long-term lapse rate (3) 1% -30% (10) Utilization of guaranteed withdrawals (4)85% -100% 94% Claims utilization factor (5) 60% -100% (10) Premiums utilization factor (5) 80% -115% (10) NPR (6) 0.08% -1.37% 0.93% Mortality rate (7) (9) (10) Volatility (8) 1% -28% 14.55% (1)Unobservable inputs were weighted by the relative fair value of the instruments, unless otherwise noted.(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 rate 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 lapse rates during the surrender charge period. (4)The utilization of guaranteed withdrawals input represents the estimated percentage of contract holders that utilize the guaranteed withdrawal feature.(5)The utilization factors are applied to the present value of claims or premiums, as appropriate, in the GLB reserve calculation to estimate the impact of inefficient withdrawal behavior, including taking less than or more than the maximum guaranteed withdrawal.(6)The NPR input represents the estimated additional credit spread that market participants would apply to the market observable discount rate when pricing a contract. The NPR input for direct and ceded embedded derivatives was weighted by the absolute value of the sensitivity of the reserve to the NPR assumption. The NPR input for LPR ceded derivative was weighted using a simple average.(7)The mortality rate 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. Fair value of the variable annuity GLB embedded derivatives would increase if higher volatilities were used for valuation. Volatility assumptions vary by fund due to the benchmarking of different indices. The volatility input was weighted by the relative acco

A negative number implies a favorable result where claim resolutions were more favorable than assumed. Our claim resolution rate assumption used in determining reserves is our expectation of the resolution rate we will experience over the long-term life of the block of claims. It will vary from actual experience in any one period, both favorably and unfavorably.

The range for indexed annuity contracts represents the lapse rates during the surrender charge period. (4)The utilization of guaranteed withdrawals input represents the estimated percentage of contract holders that utilize the guaranteed withdrawal feature.(5)The utilization factors are applied to the present value of claims or premiums, as appropriate, in the GLB reserve calculation to estimate the impact of inefficient withdrawal behavior, including taking less than or more than the maximum guaranteed withdrawal.(6)The NPR input represents the estimated additional credit spread that market participants would apply to the market observable discount rate when pricing a contract. The NPR input for direct and ceded embedded derivatives was weighted by the absolute value of the sensitivity of the reserve to the NPR assumption. The NPR input for LPR ceded derivative was weighted using a simple average.(7)The mortality rate 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. Fair value of the variable annuity GLB embedded derivatives would increase if higher volatilities were used for valuation. 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 rate 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 rate, utilization factors or mortality rate.
