Nature Of Operations And Basis Of Presentation
Nature Of Operations And Basis Of Presentation	LINCOLN NATIONAL CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) 1. Nature of Operations and Basis of Presentation Nature of Operations Lincoln National Corporation and its majority-owned subsidiaries (“LNC” or the “Company,” which also may be referred to as “we,” “our” or “us”) operate multiple insurance businesses through four business segments. See Note 14 for additional details. The collective group of businesses uses “Lincoln Financial Group” as its marketing identity. Through our business segments, we sell a wide range of wealth protection, accumulation and retirement income 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, indexed universal life insurance (“IUL”), term life insurance, employer-sponsored retirement plans and services, and group life, disability and dental. 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. As discussed in Note 3, on May 1, 2018, LNC and The Lincoln National Life Insurance Company (“LNL”) completed the acquisition of Liberty Life Assurance Company of Boston (“Liberty Life”). 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, 2018 (“2018 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 2018 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 six months ended June 30, 2019, are not necessarily indicative of the results that may be expected for the full year ending December 31, 2019. All material inter-company accounts and transactions have been eliminated in consolidation.

New Accounting Standards

New Accounting Standards	6 Months Ended

New Accounting Standards [Abstract]
New Accounting Standards	2. New Accounting Standards Adoption of 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 financial statements. ASUs not listed below were assessed and determined to be either not applicable or insignificant in presentation or amount. Standard Description Date of Adoption Effect on Financial Statements or Other Significant Matters ASU 2016-02, Leases and all related amendments This standard establishes a new accounting model for leases. Lessees will recognize most leases on the balance sheet as a right-of-use (“ROU”) asset and a related lease liability. The lease liability is measured as the present value of the lease payments over the lease term with the ROU asset measured at the lease liability amount and including adjustments for certain lease incentives and initial direct costs. Lease expense recognition will continue to differentiate between finance leases and operating leases resulting in a similar pattern of lease expense recognition as under current GAAP. This ASU permits a modified retrospective adoption approach that includes a number of optional practical expedients that entities may elect upon adoption. Early adoption is permitted. January 1, 2019 We adopted this standard and all related amendments, which resulted in the recognition of $ 207 million in ROU assets and $ 214 million in operating lease liabilities reported in other assets and other liabilities, respectively, on our Consolidated Balance Sheets as of January 1, 2019. Comparative periods continue to be measured and presented under historical guidance, and only the period of adoption is subject to this ASU. Also, on transition, we have elected not to reassess: 1) whether expired or existing contracts contain a lease under the new definition of a lease; 2) lease classification for expired or existing leases; and 3) whether previously capitalized initial direct costs would qualify for capitalization under this ASU. Additionally, there is not a significant difference in our pattern of lease expense recognition under this ASU, and there is no impact on cash flows. For more information, see Note 11. ASU 2017-08, Premium Amortization on Purchased Callable Debt Securities These amendments require an entity to shorten the amortization period for certain callable debt securities held at a premium so that the premium is amortized to the earliest call date. Early adoption is permitted, and the ASU requires adoption under a modified retrospective basis through a cumulative effect adjustment to the beginning balance of retained earnings. January 1, 2019 We adopted the provisions of this ASU, which did not result in a change to our existing practices; therefore, no cumulative effect adjustment was recorded. As such, there was no impact on our consolidated financial condition and results of operations. ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities These amendments change both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. These amendments retain the threshold of highly effective for hedging relationships, remove the requirement to bifurcate between the portions of the hedging relationship that are effective and ineffective, record hedge item and hedging instrument results in the same financial statement line item, require quantitative assessment initially for all hedging relationships unless the hedging relationship meets the definition of either the shortcut method or critical terms match method and allow the contractual specified index rate to be designated as the hedged risk in a cash flow hedge of interest rate risk of a variable rate financial instrument. These amendments also eliminate the benchmark interest rate concept for variable rate instruments. Early adoption is permitted. January 1, 2019 We adopted the provisions of this ASU, which did not have an impact on our consolidated financial condition and results of operations. This ASU does result in our modification of certain hedge documentation and effectiveness methods, which we have reflected in applicable disclosures in Note 6. Future Adoption of New Accounting Standards The following table provides a description of future adoptions of new accounting standards that may have an impact on our financial statements when adopted: Standard Description Projected Date of Adoption Effect on Financial Statements or Other Significant Matters ASU 2016-13, Measurement of Credit Losses on Financial Instruments These amendments adopt a new model to measure and recognize credit losses for most financial assets. The method used to measure estimated credit losses for available-for-sale (“AFS”) debt securities will be unchanged from current GAAP; however, the amendments require credit losses to be recognized through an allowance rather than as a reduction to the amortized cost of those debt securities. The amendments will permit entities to recognize improvements in credit loss estimates on AFS debt securities by reducing the allowance account immediately through earnings. The amendments will be adopted through a cumulative effect adjustment to the beginning balance of retained earnings as of the first reporting period in which the amendments are effective. Early adoption is permitted for annual periods beginning after December 15, 2018, and interim periods therein. January 1, 2020 We are currently evaluating the impact of adopting this ASU on our consolidated financial condition and results of operations, with a primary focus on our fixed maturity securities, mortgage loans and reinsurance recoverables. ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments – Credit Losses, Topic 815, Derivatives and Hedging and Topic 825, Financial Instruments These amendments clarify the measurement, recognition and presentation of the allowance for credit losses on accrued interest receivable balances; the inclusion of recoveries when estimating the allowance for credit losses; the inclusion of all ASC Topic 944 – Financial Services – Insurance reinsurance recoverables within the scope of ASC 326-20; and provide additional targeted clarifications on the calculation of the allowance for credit losses. These amendments also make targeted clarifications to ASC Topics 815 and 825. Early adoption is permitted. January 1, 2020 We are currently evaluating the impact of adopting this ASU on our consolidated financial condition and results of operations. ASU 2019-05, Financial Instruments – Credit Losses (Topic 326): Targeted Transition Relief The amendments provide entities that have certain instruments within the scope of Subtopic 326-20, Financial Instruments – Credit Losses – Measured at Amortized Cost , with an option to irrevocably elect the fair value option in Subtopic 825-10, Financial Instruments – Overall , applied on an instrument-by-instrument basis for eligible instruments , upon adoption of ASC Topic 326. January 1, 2020 We are currently evaluating the impact of adopting this ASU on our consolidated financial condition and results of operations. Standard Description Projected Date of Adoption Effect on Financial Statements or Other Significant Matters ASU 2018-12, Targeted Improvements to the Accounting for Long-Duration Contracts These 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 (“DAC”). 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, 2021, and early adoption is permitted. On July 17, 2019, the FASB, in a public meeting, voted to defer the implementation date for ASU 2018-12 for large public SEC filers to January 1, 2022. If adopted, we will update our projected date of adoption accordingly. January 1, 2021 We are currently evaluating the impact of adopting this ASU on our consolidated financial condition and results of operations.

Acquisition [Abstract]
Acquisition	3. Acquisition On May 1, 2018 , we completed the acquisition of 100 % of the capital stock of Liberty Life, which operates a group benefits business (“Liberty Group Business”) and individual life and individual and group annuity business (the “Liberty Life Business”), from Liberty Mutual Insurance Company in a transaction accounted for under the acquisition method of accounting pursuant to Business Combinations Topic 805 (“Topic 805”). The acquisition expanded the scale and capabilities of the Group Protection business while further diversifying the Company’s sources of earnings. In connection with the acquisition and pursuant to the Master Transaction Agreement (“MTA”), dated January 18, 2018, which was attached as Exhibit 2.1 to the Company’s Current Report on Form 8-K filed on January 22, 2018, Liberty Life sold the Liberty Life Business on May 1, 2018, by entering into reinsurance agreements and related ancillary documents (including administrative services agreements and transition services agreements) with Protective Life Insurance Company and its wholly-owned subsidiary, Protective Life and Annuity Insurance Company (together with Protective Life Insurance Company, “Protective”), providing for the reinsurance and administration of the Liberty Life Business. Since the May 1, 2018 acquisition date, we have adjusted assets acquired by $( 5 ) million and liabilities acquired by $ 23 million for an increase in goodwill of $ 28 million. Under the terms of the MTA, a final balance sheet will be agreed upon at a later date. The following table presents the adjusted fair values (in millions) of the net assets acquired related to the Liberty Group Business: Adjusted Fair Value Assets Investments $ 2,493 Mortgage loans on real estate 658 Cash and invested cash 107 Reinsurance recoverables 76 Premiums and fees receivable 83 Accrued investment income 24 Other intangible assets acquired 640 Other assets acquired 142 Separate account assets 99 Total assets acquired $ 4,322 Liabilities Future contract benefits $ 2,930 Other contract holder funds 46 Other liabilities acquired 140 Separate account liabilities 99 Total liabilities assumed $ 3,215 Net identifiable assets acquired $ 1,107 Goodwill 410 Net assets acquired $ 1,517

Variable Interest Entities [Abstract]
Variable Interest Entities	4. Variable Interest Entities Consolidated VIEs Asset information (dollars in millions) for the consolidated variable interest entities (“VIEs”) included on our Consolidated Balance Sheets was as follows: As of June 30, 2019 As of December 31, 2018 Number Number of Notional Carrying of Notional Carrying Instruments Amounts Value Instruments Amounts Value Assets Fixed maturity securities: Total return swap 1 $ 596 $ - 1 $ 600 $ - Total assets 1 $ 596 $ - 1 $ 600 $ - As of June 30, 2019, and December 31, 2018, there were no gains or losses for consolidated VIEs recognized on our Consolidated Statements of Comprehensive Income (Loss). Unconsolidated VIEs Structured Securities Through our investment activities, we make passive investments in structured securities issued by VIEs for which we are not the manager. These structured securities include our asset-backed securities (“ABS”), residential mortgage-backed securities (“RMBS”), commercial mortgage-backed securities (“CMBS”) and collateralized loan obligations (“CLOs”). 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”), including qualified affordable housing projects, that we have concluded are VIEs. 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 $ 1.9 billion and $ 1.7 billion as of June 30, 2019, and December 31, 2018, respectively. Included in these carrying amounts are our investments in qualified affordable housing projects, which were $ 16 million and $ 20 million as of June 30, 2019, and December 31, 2018, respectively. We do not have any contingent commitments to provide additional capital funding to these qualified affordable housing projects. We received returns from these qualified affordable housing projects in the form of income tax credits and other tax benefits of less than $ 1 million for the six months ended June 30, 2019 and 2018, which were recognized in federal income tax expense (benefit) on our Consolidated Statements of Comprehensive Income (Loss). Our exposure to loss is limited to the capital we invest in the LPs and LLCs, and there have been no indicators of impairment that would require us to recognize an impairment loss related to the LPs and LLCs as of June 30, 2019.

The amortized cost and fair value of fixed maturity AFS securities by contractual maturities (in millions) as of June 30, 2019, were as follows: Amortized Fair Cost Value Due in one year or less $ 3,340 $ 3,324 Due after one year through five years 15,342 15,844 Due after five years through ten years 17,216 18,385 Due after ten years 47,823 54,381 Subtotal 83,721 91,934 Structured securities (ABS, MBS, CLOs) 7,469 7,799 Total fixed maturity AFS securities $ 91,190 $ 99,733 Actual maturities may differ from contractual maturities because issuers may have the right to call or pre-pay obligations. The fair value and gross unrealized losses, including the portion of OTTI recognized in other comprehensive income (loss) (“OCI”), of fixed maturity AFS securities (dollars in millions), aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position, were as follows: As of June 30, 2019 Less Than or Equal Greater Than to Twelve Months Twelve Months Total Gross Gross Gross Unrealized Unrealized Unrealized Fair Losses and Fair Losses and Fair Losses and Value OTTI Value OTTI Value OTTI Fixed maturity AFS securities: Corporate bonds $ 1,188 $ 42 $ 6,168 $ 309 $ 7,356 $ 351 ABS 36 - 86 10 122 10 RMBS 11 - 480 11 491 11 CLOs 481 2 204 5 685 7 State and municipal bonds 115 1 82 3 197 4 Hybrid and redeemable preferred securities 72 1 109 24 181 25 Total fixed maturity AFS securities $ 1,903 $ 46 $ 7,129 $ 362 $ 9,032 $ 408 Total number of fixed maturity AFS securities in an unrealized loss position 890 As of December 31, 2018 Less Than or Equal Greater Than to Twelve Months Twelve Months Total Gross Gross Gross Unrealized Unrealized Unrealized Fair Losses and Fair Losses and Fair Losses and Value OTTI Value OTTI Value OTTI Fixed maturity AFS securities: Corporate bonds $ 32,493 $ 1,530 $ 7,228 $ 735 $ 39,721 $ 2,265 ABS 117 2 143 14 260 16 U.S. government bonds 70 1 23 1 93 2 RMBS 472 10 863 60 1,335 70 CMBS 470 11 82 5 552 16 CLOs 1,124 21 103 3 1,227 24 State and municipal bonds 404 8 96 10 500 18 Hybrid and redeemable preferred securities 96 6 133 28 229 34 Total fixed maturity AFS securities $ 35,246 $ 1,589 $ 8,671 $ 856 $ 43,917 $ 2,445 Total number of fixed maturity AFS securities in an unrealized loss position 3,414 The fair value, gross unrealized losses, the portion of OTTI recognized in OCI (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 June 30, 2019 Number Fair Gross Unrealized of Value Losses OTTI Securities (1) Less than six months $ 44 $ 15 $ 1 15 Six months or greater, but less than nine months 47 16 - 5 Nine months or greater, but less than twelve months 2 1 - 2 Twelve months or greater 214 93 14 33.0 35 Total $ 307 $ 125 $ 15 57 As of December 31, 2018 Number Fair Gross Unrealized of Value Losses OTTI Securities (1) Less than six months $ 395 $ 124 $ 1 45 Six months or greater, but less than nine months 96 49 - 11 Nine months or greater, but less than twelve months 11 8 - 2 Twelve months or greater 143 74 8 32 Total $ 645 $ 255 $ 9 90 (1) We may reflect a security in more than one aging category based on various purchase dates. We regularly review our investment holdings for OTTI. Our gross unrealized losses, including the portion of OTTI recognized in OCI, on fixed maturity AFS securities decreased by $ 2.0 billion for the six months ended June 30, 2019. As discussed further below, we believe the unrealized loss position as of June 30, 2019, did not represent OTTI 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 estimated future cash flows were equal to or greater than the amortized cost basis of the debt securities. Based upon this evaluation as of June 30, 2019, management believes we have the ability to generate adequate amounts of cash from our normal operations (e.g., insurance premiums and fees and investment income) to meet cash requirements with a prudent margin of safety without requiring the sale of our temporarily-impaired securities. As of June 30, 2019, the unrealized losses associated with our corporate 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 temporarily-impaired security. As of June 30, 2019, the unrealized losses associated with our mortgage-backed securities (“MBS”) 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 temporarily-impaired security. As of June 30, 2019, 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 temporarily-impaired security. Changes in the amount of credit loss of OTTI recognized in net income (loss) where the portion related to other factors was recognized in OCI (in millions) on fixed maturity AFS securities were as follows: For the Three For the Six Months Ended Months Ended June 30, June 30, 2019 2018 2019 2018 Balance as of beginning-of-period $ 359 $ 378 $ 355 $ 378 Increases attributable to: Credit losses on securities for which an OTTI was not previously recognized 5 1 11 2 Credit losses on securities for which an OTTI was previously recognized - - 2 1 Decreases attributable to: Securities sold, paid down or matured ( 111 ) ( 4 ) ( 115 ) ( 6 ) Balance as of end-of-period $ 253 $ 375 $ 253 $ 375 During the three and six months ended June 30, 2019 and 2018, we recorded credit losses on securities for which an OTTI was not previously recognized as we determined the cash flows expected to be collected would not be sufficient to recover the entire amortized cost basis of the debt security. The credit losses we recorded on securities for which an OTTI was not previously recognized were attributable primarily to one or a combination of the following reasons:  Failure of the issuer of the security to make scheduled payments;  Deterioration of creditworthiness of the issuer;  Deterioration of conditions specifically related to the security;  Deterioration of fundamentals of the industry in which the issuer operates; and  Deterioration of the rating of the security by a rating agency. We recognize the OTTI attributed to the noncredit portion as a separate component in OCI referred to as unrealized OTTI on fixed maturity AFS securities. Determination of Credit Losses on Corporate Bonds As of June 30, 2019, and December 31, 2018, we reviewed our corporate bond portfolio for potential shortfalls in contractual principal and interest based on numerous subjective and objective inputs. The factors used to determine the amount of credit loss for each individual security, include, but are not limited to, near-term risk, substantial discrepancy between book and market value, sector or company-specific volatility, negative operating trends and trading levels wider than peers. Credit ratings express opinions about the credit quality of a security. Securities rated investment grade, those rated BBB- or higher by Standard & Poor’s (“S&P”) Rating Services 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 June 30, 2019, and December 31, 2018, 96 % of the fair value of our corporate bond portfolio was rated investment grade. As of June 30, 2019, and December 31, 2018, the portion of our corporate bond portfolio rated below investment grade had an amortized cost of $ 3.2 billion and a fair value of $ 3.2 billion and $ 3.0 billion, respectively. Based upon the analysis discussed above, we believe as of June 30, 2019, and December 31, 2018, that we would recover the amortized cost of each corporate bond. Determination of Credit Losses on MBS and ABS As of June 30, 2019, and December 31, 2018, default rates were projected by considering underlying MBS and ABS loan performance and collateral type. Projected default rates on existing delinquencies vary depending on loan type and severity of delinquency status. In addition, we estimate the potential contributions of currently performing loans that may become delinquent in the future based on the change in delinquencies and loan liquidations experienced in the recent history. Finally, we develop a default rate timing curve by aggregating the defaults for all loans in the pool (delinquent loans, foreclosure and real estate owned and new delinquencies from currently performing loans) and the associated loan-level loss severities. We use certain available loan characteristics such as lien status, loan sizes and occupancy to estimate the loss severity of loans. Second lien loans are assigned 100 % severity, if defaulted. For first lien loans, we assume a minimum of 30 % severity with higher severity assumed for investor properties and further adjusted by housing price assumptions. With the default rate timing curve and loan-level loss severity, we derive the future expected credit losses. Mortgage Loans on Real Estate The following provides the current and past due composition of our mortgage loans on real estate (in millions): As of June 30, 2019 As of December 31, 2018 Commercial Residential Total Commercial Residential Total Current $ 14,436 $ 645 $ 15,081 $ 13,029 $ 239 $ 13,268 60 to 90 days past due - 5 5 - 1 1 Greater than 90 days past due - 2 2 - - - Valuation allowance - ( 2 ) ( 2 ) - - - Unamortized premium (discount) ( 17 ) 21 4 ( 17 ) 8 ( 9 ) Total carrying value $ 14,419 $ 671 $ 15,090 $ 13,012 $ 248 $ 13,260 We establish a valuation allowance to provide for the risk of credit losses inherent in our portfolio. The valuation allowance includes specific valuation allowances for loans that are deemed to be impaired as well as general valuation allowances for pools of loans with similar risk characteristics where a property risk or market specific risk has not been identified but for which we anticipate a loss has occurred. For our commercial mortgage loans, no specifically identified loans were impaired as of June 30, 2019, or December 31, 2018. For our residential mortgage loans, no specifically identified loans were impaired as of June 30, 2019, or December 31, 2018. The general allowance established on residential mortgage loans as of June 30, 2019 was $ 2 million. As of December 31, 2018, the general allowance established on residential mortgage loans was less than $ 1 million. The changes in the valuation allowance associated with impaired commercial mortgage loans on real estate (in millions) were as follows: For the Three For the Six Months Ended Months Ended June 30, June 30, 2019 2018 2019 2018 Balance as of beginning-of-period $ - $ 3 $ - $ 3 Additions - - - - Charge-offs, net of recoveries - ( 1 ) - ( 1 ) Balance as of end-of-period $ - $ 2 $ - $ 2 Additional information related to impaired commercial mortgage loans on real estate (in millions) was as follows: For the Three For the Six Months Ended Months Ended June 30, June 30, 2019 2018 2019 2018 Average carrying value for impaired commercial mortgage loans on real estate $ - $ 7 $ - $ 7 Interest income recognized on impaired commercial mortgage loans on real estate - - - - Interest income collected on impaired commercial mortgage loans on real estate - - - - We use the loan-to-value and debt-service coverage ratios as credit quality indicators for our commercial mortgage loans on real estate (dollars in millions) as follows: As of June 30, 2019 As of December 31, 2018 Debt- Debt- Service Service Carrying % of Coverage Carrying % of Coverage Loan-to-Value Ratio Value Total Ratio Value Total Ratio Less than 65% $ 12,989 90.1 % 2.32 $ 11,716 90.1 % 2.30 65% to 74% 1,429 9.9 % 1.81 1,238 9.5 % 1.76 75% to 100% 1 0.0 % 1.09 58 0.4 % 0.95 Total $ 14,419 100.0 % $ 13,012 100.0 % We use loan performance status as the primary credit quality indicator for our residential mortgage loans on real estate (dollars in millions) as follows: As of June 30, 2019 As of December 31, 2018 Carrying % of Carrying % of Performance Indicator Value Total Value Total Performing $ 664 99.0 % $ 247 99.6 % Nonperforming 7 1.0 % 1 0.4 % Total $ 671 100.0 % $ 248 100.0 % Our commercial mortgage loan portfolio is geographically diversified throughout the U.S. with the largest concentrations in California, which accounted for 23 % of commercial mortgage loans on real estate as of June 30, 2019, and December 31, 2018, and Texas, which accounted for 12 % of commercial mortgage loans on real estate as of June 30, 2019, and December 31, 2018.

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 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 13 for additional disclosures related to the fair value of our derivative instruments. We adopted ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities, in 2019. See Note 2 for additional information. 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 and anticipated issuances of fixed-rate securities. 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-rate long-term debt and fixed maturity securities due to interest rate risks. Treasury and Reverse Treasury Locks We use treasury locks designated and qualifying as cash flow hedges to hedge the interest rate exposure related to our issuance of fixed-rate securities or the anticipated future cash flows of floating-rate fixed maturity securities due to changes in interest rates. In addition, 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 We use call options to hedge the liability exposure on certain options in 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. Contract holders may elect to rebalance index options at renewal dates, either annually or biannually. As of each renewal date, we have the opportunity to re-price the indexed component by establishing participation rates, caps, spreads and specified rates, subject to contractual guarantees. We purchase 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. 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. Variance Swaps We use variance swaps to hedge the liability exposure on certain options in variable annuity products. Variance swaps are contracts entered into at no cost whose payoff is the difference between the realized variance rate of an underlying index and the fixed variance rate determined as of inception of the contract. 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 to hedge the liability exposure on certain options in variable annuity products. We buy credit default swaps to hedge against a drop in bond prices due to credit concerns of certain bond issuers. A credit default swap 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. Credit Default Swaps – Selling Protection We use credit default swaps to hedge the liability exposure on certain options in variable annuity products. We sell credit default swaps to offer credit protection to contract holders and investors. The credit default swaps hedge the contract holders and investors against a drop in bond prices due to credit concerns of certain bond issuers. A credit default swap 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. Embedded Derivatives We have embedded derivatives that include: GLB Reserves Embedded Derivatives 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 GWB and GIB features. 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 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 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. 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 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 GLB feature. 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. Contract holders may elect to rebalance index options at renewal dates, either annually or biannually. As of each renewal date, we have the opportunity to re-price the indexed component by establishing participation rates, caps, spreads and specified rates, subject to contractual guarantees. We purchase S&P 500 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. Reinsurance Related Embedded Derivatives We have certain modified coinsurance arrangements and coinsurance with funds withheld reinsurance arrangements 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 arrangements. 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 June 30, 2019 As of December 31, 2018 Notional Fair Value Notional Fair Value Amounts Asset Liability Amounts Asset Liability Qualifying Hedges Cash flow hedges: Interest rate contracts (1) $ 2,437 $ 127 $ 184 $ 2,741 $ 70 $ 9 Foreign currency contracts (1) 2,519 226 38 2,326 167 39 Total cash flow hedges 4,956 353 222 5,067 237 48 Fair value hedges: Interest rate contracts (1) 1,261 115 196 1,268 55 137 Non-Qualifying Hedges Interest rate contracts (1) 98,765 883 125 100,628 464 138 Foreign currency contracts (1) 284 - 1 47 - - Equity market contracts (1) 36,021 774 429 30,487 676 162 Embedded derivatives: GLB direct (2) (3) - - 1 - 123 - GLB ceded (2) - 111 - - 72 - Reinsurance related (4) - - 310 - - 3 Indexed annuity and IUL contracts (2) (5) - 903 1,973 - 902 1,305 Total derivative instruments $ 141,287 $ 3,139 $ 3,257 $ 137,497 $ 2,529 $ 1,793 (1) Reported in derivative investments and other liabilities on our Consolidated Balance Sheets.

This reclassification would be due primarily to interest rate variances related to our interest rate swap agreements. For the six months ended June 30, 2019 and 2018 , 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 June 30, 2019, and December 31, 2018, we did not have any exposure related to credit default swaps 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 (“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 June 30, 2019, 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, our insurance subsidiaries 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. As of June 30, 2019, and December 31, 2018, our exposure was zero . 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 June 30, 2019 As of December 31, 2018 Collateral Collateral Collateral Collateral Posted by Posted by Posted by Posted by S&P Counter- LNC Counter- LNC Credit Party (Held by Party (Held by Rating of (Held by Counter- (Held by Counter- Counterparty LNC) Party) LNC) Party) AA- $ 306 $ ( 186 ) $ 33 $ ( 3 ) A+ 466 ( 212 ) 296 ( 96 ) A 12 ( 30 ) 106 ( 56 ) A- 18 - 4 - BBB+ 337 ( 33 ) 197 - $ 1,139 $ ( 461 ) $ 636 $ ( 155 ) Balance Sheet Offsetting Information related to the effects of offsetting (in millions) was as follows: As of June 30, 2019 Embedded Derivative Derivative Instruments Instruments Total Financial Assets Gross amount of recognized assets $ 1,938 $ 1,014 $ 2,952 Gross amounts offset ( 428 ) - ( 428 ) Net amount of assets 1,510 1,014 2,524 Gross amounts not offset: Cash collateral ( 1,139 ) - ( 1,139 ) Non-cash collateral ( 133 ) - ( 133 ) Net amount $ 238 $ 1,014 $ 1,252 Financial Liabilities Gross amount of recognized liabilities $ 1,066 $ 2,284 $ 3,350 Gross amounts offset ( 186 ) - ( 186 ) Net amount of liabilities 880 2,284 3,164 Gross amounts not offset: Cash collateral ( 461 ) - ( 461 ) Non-cash collateral ( 209 ) - ( 209 ) Net amount $ 210 $ 2,284 $ 2,494 As of December 31, 2018 Embedded Derivative Derivative Instruments Instruments Total Financial Assets Gross amount of recognized assets $ 1,330 $ 1,097 $ 2,427 Gross amounts offset ( 223 ) - ( 223 ) Net amount of assets 1,107 1,097 2,204 Gross amounts not offset: Cash collateral ( 636 ) - ( 636 ) Non-cash collateral ( 58 ) - ( 58 ) Net amount $ 413 $ 1,097 $ 1,510 Financial Liabilities Gross amount of recognized liabilities $ 784 $ 1,308 $ 2,092 Gross amounts offset ( 103 ) - ( 103 ) Net amount of liabilities 681 1,308 1,989 Gross amounts not offset: Cash collateral ( 155 ) - ( 155 ) Non-cash collateral ( 190 ) - ( 190 ) Net amount $ 336 $ 1,308 $ 1,644

Federal Income Taxes

Federal Income Taxes [Abstract]
Federal Income Taxes	7. Federal Income Taxes The effective tax rate is the ratio of tax expense over pre-tax income (loss). The effective tax rate was 14 % and 11 % for the three and six months ended June 30, 2019, respectively, compared to 15 % for each of the corresponding periods in 2018. The effective tax rate on pre-tax income was lower than the prevailing corporate federal income tax rate of 21 %. Differences between the effective rates and the corporate federal income tax rate were primarily the result of the separate account dividends-received deduction, certain tax preferred investment income, foreign tax credits and other tax preference items. The six months ended June 30, 2019, effective tax rate is lower than the corresponding period in 2018 as a result of an increased level of realized losses and the associated tax benefit resulting from the application of the corporate federal income tax rate of 21 %.

Reinsurance [Abstract]
Reinsurance	8. Reinsurance Modified Coinsurance Reinsurance Transaction Some portions of our annuity business have been reinsured on a modified coinsurance (“Modco”) basis with other companies. In a Modco program, 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. to reinsure fixed and fixed indexed annuity products. We held investments of $ 7.6 billion as of June 30, 2019, in support of reserves associated with the transaction in a Modco portfolio. As of June 30, 2019, the portfolio included fixed maturity AFS securities, trading securities, equity securities, commercial mortgage loans, derivative investments and cash that had carrying values of $ 3.3 billion, $ 3.2 billion, $ 81 million, $ 583 million, $ 119 million and $ 350 million, respectively, as of June 30, 2019. In addition, the portfolio was supported by $ 233 million of over-collateralization and a $ 205 million letter of credit as of June 30, 2019. In repositioning the Modco investment portfolio, purchases of securities classified as trading during the first half of 2019 primarily resulted in negative cash flows from operating activities that were largely offset by sales of securities classified as AFS within investing activities in our Consolidated Statements of Cash Flows. See “Realized Gain (Loss)” in Note 5 for information on reinsurance related embedded derivatives.

Guaranteed Benefit Features Information on the guaranteed death benefit (“GDB”) features outstanding (dollars in millions) was as follows: As of As of June 30, December 31, 2019 (1) 2018 (1) Return of Net Deposits Total account value $ 97,434 $ 89,783 Net amount at risk (2) 112 1,002 Average attained age of contract holders 65 years 65 years Minimum Return Total account value $ 94 $ 88 Net amount at risk (2) 15 18 Average attained age of contract holders 77 years 77 years Guaranteed minimum return 5 % 5 % Anniversary Contract Value Total account value $ 25,166 $ 23,365 Net amount at risk (2) 445 2,007 Average attained age of contract holders 71 years 71 years (1) Our variable contracts with guarantees may offer more than one type of guarantee in each contract; therefore, the amounts listed are not mutually exclusive. (2) Represents the amount of death benefit in excess of the account balance that is subject to market fluctuations. 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 Six Months Ended June 30, 2019 2018 Balance as of beginning-of-year $ 161 $ 100 Changes in reserves ( 35 ) 18 Benefits paid ( 11 ) ( 7 ) Balance as of end-of-period $ 115 $ 111 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 of As of June 30, December 31, 2019 2018 Asset Type Domestic equity $ 60,173 $ 54,060 International equity 20,072 18,359 Fixed income 40,134 37,942 Total $ 120,379 $ 110,361 Percent of total variable annuity separate account values 98 % 99 % 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 % and 35 % of total life insurance in-force reserves as of June 30, 2019, and December 31, 2018, respectively. UL and VUL products with secondary guarantees represented 29 % of total life insurance sales for the three and six months ended June 30, 2019, compared to 30 % and 33 %, respectively, for the corresponding periods in 2018.

Liability For Unpaid Claims [Abstract]
Liability For Unpaid Claims	10. 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 Six Months Ended June 30, 2019 2018 Balance as of beginning-of-year $ 5,335 $ 2,222 Reinsurance recoverable 143 57 Net balance as of beginning-of-year 5,192 2,165 Business acquired (1) - 2,836 Incurred related to: Current year 1,577 986 Prior years: Interest 80 50 All other incurred (2) ( 144 ) ( 87 ) Total incurred 1,513 949 Paid related to: Current year ( 593 ) ( 393 ) Prior years ( 810 ) ( 517 ) Total paid ( 1,403 ) ( 910 ) Net balance as of end-of-period 5,302 5,040 Reinsurance recoverable 147 136 Balance as of end-of-period $ 5,449 $ 5,176 (1) Represents Liberty group life and disability reserves, net, as of May 1, 2018. See Note 3 for additional information. (2) 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.

Contingencies and Commitments

Contingencies and Commitments	6 Months Ended

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. LNC is 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 LNC 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 June 30, 2019. While the potential future charges could be material in the particular quarterly or annual periods in which they are recorded, based on information currently known by management, management does not believe any such charges are likely to have a material adverse effect on LNC’s financial condition. 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 June 30, 2019 , we estimate the aggregate range of reasonably possible losses to be up to approximately $ 50 million. 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 . Certain reinsurers have sought rate increases on certain yearly renewable term treaties. We are disputing the requested rate increases under these treaties. We have initiated and will initiate arbitration proceedings, as necessary, under these treaties in order to protect our contractual rights. Additionally, reinsurers may initiate arbitration proceedings against us. We believe it is unlikely the outcome of these disputes will have a material adverse effect on our financial condition. Cost of Insurance Litigation Glover v.

Commitments Leases Effective January 1, 2019, we adopted ASU 2016-02, which resulted in a new measurement and recognition of our long-term operating leases on our Consolidated Balance Sheets. See Note 2 for additional information. We lease office space and certain equipment under various long-term lease agreements, and we also enter into sale-leaseback transactions. 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 initial lease liability amount, plus any lease payments made at or before the commencement date, minus any lease incentives received, plus any initial direct costs incurred. Our lease terms may include options to extend or terminate the lease when it is 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. We recognized operating lease ROU assets of $ 189 million and associated lease liabilities of $ 198 million as of June 30, 2019. We classified the operating lease ROU assets within other assets and the lease liabilities within other liabilities on our Consolidated Balance Sheets. The weighted-average discount rate and remaining lease term on our operating leases was 3.3 % and 6 years, respectively, as of June 30, 2019. Operating lease expense for the three and six months ended June 30, 2019, was $ 13 million and $ 27 million, respectively, and reported in commissions and other expenses on our Consolidated Statements of Comprehensive Income (Loss) . As of June 30, 2019, the net book value of assets recorded as finance leases under sale-leaseback transactions was $ 159 million, and the associated accumulated amortization was $ 318 million. These transactions have been classified as other assets on our Consolidated Balance Sheets. These assets will continue to be amortized on a straight-line basis over the assets’ remaining lives. The weighted-average discount rate and remaining lease term on our sale-leaseback transactions was 2.7 % and 3 years, respectively, as of June 30, 2019. Finance lease expense (in millions) was as follows: For the Three For the Six Months Months Ended Ended June 30, 2019 June 30, 2019 Amortization of ROU assets (1) $ 19 $ 37 Interest on lease liabilities (2) 4 7 Total $ 23 $ 44 (1) Amortization of ROU assets is reported in commissions and other expenses on our Consolidated Statements of Comprehensive Income (Loss) . (2) Interest on lease liabilities is reported in interest and debt expense on our Consolidated Statements of Comprehensive Income (Loss) . The table below presents cash flow information (in millions) related to leases: For the Six Months Ended June 30, 2019 Supplemental Cash Flow Information Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 30 Financing cash flows from finance leases 7 Supplemental Non-cash Information ROU assets obtained in exchange for new lease obligations: Operating leases $ 13 Our future minimum lease payments (in millions) under non-cancellable leases as of June 30, 2019, were as follows: Operating Finance Leases Leases Remainder of 2019 $ 21 $ 90 2020 39 58 2021 38 67 2022 33 67 2023 30 91 Thereafter 67 28 Total future minimum lease payments 228 401 Less: Amount representing interest 30 37 Present value of minimum lease payments $ 198 $ 364 As of June 30, 2019, we had additional office space leases that had not yet commenced totaling $ 40 million. These leases will commence in the third and fourth quarters of 2019 and have lease terms of 7 to 11 years.

Shares and Stockholders' Equity	12. Shares and Stockholders’ Equity Common Shares The changes in our common stock (number of shares) were as follows: For the Three For the Six Months Ended Months Ended June 30, June 30, 2019 2018 2019 2018 Common Stock Balance as of beginning-of-period 202,987,229 218,695,476 205,862,760 218,090,114 Stock issued for exercise of warrants 18,493 2,826 222,023 22,866 Stock compensation/issued for benefit plans 83,405 51,644 893,075 636,966 Retirement/cancellation of shares ( 2,313,396 ) ( 1,455,895 ) ( 6,202,127 ) ( 1,455,895 ) Balance as of end-of-period 200,775,731 217,294,051 200,775,731 217,294,051 Common Stock as of End-of-Period Basic basis 200,775,731 217,294,051 200,775,731 217,294,051 Diluted basis 202,245,662 220,722,270 202,245,662 220,722,270 Our common stock is without par value. Average Shares A reconciliation of the denominator (number of shares) in the calculations of basic and diluted earnings (loss) per common share was as follows: For the Three For the Six Months Ended Months Ended June 30, June 30, 2019 2018 2019 2018 Weighted-average shares, as used in basic calculation 201,498,137 217,997,297 202,886,733 218,182,118 Shares to cover exercise of outstanding warrants 57,189 639,071 115,513 640,929 Shares to cover non-vested stock 831,385 1,475,976 940,471 1,534,469 Average stock options outstanding during the period 1,647,523 1,752,403 1,583,354 1,860,997 Assumed acquisition of shares with assumed proceeds from exercising outstanding warrants ( 8,610 ) ( 91,876 ) ( 18,893 ) ( 86,482 ) Assumed acquisition of shares with assumed proceeds and benefits from exercising stock options (at average market price for the period) ( 1,119,711 ) ( 1,086,798 ) ( 1,080,671 ) ( 1,094,976 ) Shares repurchasable from measured but unrecognized stock option expense - ( 16,356 ) ( 434 ) ( 20,467 ) Average deferred compensation shares - 934,869 - 928,466 Weighted-average shares, as used in diluted calculation 202,905,913 221,604,586 204,426,073 221,945,054 In the event the average market price of LNC common stock exceeds the issue price of stock options and the options have a dilutive effect to our earnings per share (“EPS”), such options will be shown in the table above. We have participants in our deferred compensation plans who selected LNC stock as the measure for the investment return attributable to all or a portion of their deferral amounts. For the three and six months ended June 30, 2018, the effect of settling this obligation in LNC stock (“equity classification”) was more dilutive than the scenario of settling in cash (“liability classification”). Therefore, for our EPS calculation for these periods, we added these shares to the denominator and adjusted the numerator to present net income as if the shares had been accounted for under equity classification by removing the mark-to-market adjustment included in net income attributable to these deferred units of LNC stock. The amount of this adjustment was $ 8 million and $ 10 million for the three and six months ended June 30, 2018, respectively. AOCI The following summarizes the components and changes in AOCI (in millions): For the Six Months Ended June 30, 2019 2018 Unrealized Gain (Loss) on AFS Securities Balance as of beginning-of-year $ 557 $ 3,486 Cumulative effect from adoption of new accounting standards - 674 Unrealized holding gains (losses) arising during the period 6,933 ( 4,891 ) Change in foreign currency exchange rate adjustment 3 ( 50 ) Change in DAC, VOBA, DSI, future contract benefits and other contract holder funds ( 1,903 ) 1,395 Income tax benefit (expense) ( 1,070 ) 749 Less: Reclassification adjustment for gains (losses) included in net income (loss) ( 12 ) ( 29 ) Associated amortization of DAC, VOBA, DSI and DFEL ( 5 ) ( 10 ) Income tax benefit (expense) 4 8 Balance as of end-of-period $ 4,533 $ 1,394 Unrealized OTTI on AFS Securities Balance as of beginning-of-year $ 33 $ 44 (Increases) attributable to: Cumulative effect from adoption of new accounting standards - 9 Gross OTTI recognized in OCI during the period ( 16 ) - Change in DAC, VOBA, DSI and DFEL 1 - Income tax benefit (expense) 3 - Decreases attributable to: Changes in fair value, sales, maturities or other settlements of AFS securities 19 ( 7 ) Change in DAC, VOBA, DSI and DFEL ( 3 ) ( 11 ) Income tax benefit (expense) ( 3 ) 4 Balance as of end-of-period $ 34 $ 39 Unrealized Gain (Loss) on Derivative Instruments Balance as of beginning-of-year $ 139 $ ( 29 ) Cumulative effect from adoption of new accounting standard - ( 6 ) Unrealized holding gains (losses) arising during the period ( 32 ) 87 Change in foreign currency exchange rate adjustment ( 5 ) 50 Change in DAC, VOBA, DSI and DFEL ( 5 ) 4 Income tax benefit (expense) 8 ( 29 ) Less: Reclassification adjustment for gains (losses) included in net income (loss) 20 11 Associated amortization of DAC, VOBA, DSI and DFEL ( 2 ) ( 1 ) Income tax benefit (expense) ( 4 ) ( 2 ) Balance as of end-of-period $ 91 $ 69 Foreign Currency Translation Adjustment Balance as of beginning-of-year $ ( 23 ) $ ( 14 ) Foreign currency translation adjustment arising during the period - ( 4 ) Balance as of end-of-period $ ( 23 ) $ ( 18 ) Funded Status of Employee Benefit Plans Balance as of beginning-of-year $ ( 299 ) $ ( 257 ) Cumulative effect from adoption of new accounting standard - ( 35 ) Adjustment arising during the period - 9 Balance as of end-of-period $ ( 299 ) $ ( 283 ) The following summarizes the reclassifications out of AOCI (in millions) and the associated line item in the Consolidated Statements of Comprehensive Income (Loss): For the Six Months Ended June 30, 2019 2018 Unrealized Gain (Loss) on AFS Securities Gross reclassification $ ( 12 ) $ ( 29 ) Total realized gain (loss) Associated amortization of DAC, VOBA, DSI and DFEL ( 5 ) ( 10 ) Total realized gain (loss) Reclassification before income Income (loss) from continuing tax benefit (expense) ( 17 ) ( 39 ) operations before taxes Income tax benefit (expense) 4 8 Federal income tax expense (benefit) Reclassification, net of income tax $ ( 13 ) $ ( 31 ) Net income (loss) Unrealized OTTI on AFS Securities Gross reclassification $ 5 $ - Total realized gain (loss) Change in DAC, VOBA, DSI and DFEL - - Total realized gain (loss) Reclassification before income Income (loss) from continuing tax benefit (expense) 5 - operations before taxes Income tax benefit (expense) ( 1 ) - Federal income tax expense (benefit) Reclassification, net of income tax $ 4 $ - Net income (loss) Unrealized Gain (Loss) on Derivative Instruments Gross reclassifications: Interest rate contracts $ 2 $ 2 Net investment income Interest rate contracts ( 1 ) ( 2 ) Interest and debt expense Foreign currency contracts 15 11 Net investment income Foreign currency contracts 4 - Total realized gain (loss) Total gross reclassifications 20 11 Associated amortization of DAC, VOBA, DSI and DFEL ( 2 ) ( 1 ) Commissions and other expenses Reclassifications before income Income (loss) from continuing tax benefit (expense) 18 10 operations before taxes Income tax benefit (expense) ( 4 ) ( 2 ) Federal income tax expense (benefit) Reclassifications, net of income tax $ 14 $ 8 Net income (loss)

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 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 are classified as Level 2 within the fair value hierarchy. Other Investments The carrying value of our assets classified as other 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 1 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 June 30, 2019, and December 31, 2018, 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. 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 June 30, 2019, or December 31, 2018, and we noted no changes in our valuation methodologies between these periods.

For the three and six months ended June 30, 2019 and 2018, transfers in and out of Level 3 were attributable primarily to the securities’ observable market information no longer being available or becoming available. In 2018, transfers into or out of Level 3 also included FHLB stock between equity securities and other investments at cost on our Consolidated Balance Sheets. Transfers into and out of Levels 1 and 2 are generally the result of a change in the type of input used to measure the fair value of an asset or liability at the end of the reporting period. When quoted prices in active markets become available, transfers from Level 2 to Level 1 will result. When quoted prices in active markets become unavailable, but we are able to employ a valuation methodology using significant observable inputs, transfers from Level 1 to Level 2 will result. For the three and six months ended June 30, 2019 and 2018, the transfers between Levels 1 and 2 of the fair value hierarchy were less than $ 1 million for our financial instruments carried at fair value. The following summarizes the fair value (in millions), valuation techniques and significant unobservable inputs of the Level 3 fair value measurements as of June 30, 2019: Fair Valuation Significant Assumption or Value Technique Unobservable Inputs Input Ranges Assets Investments: Fixed maturity AFS and trading securities: Corporate bonds $ 2,708 Discounted cash flow Liquidity/duration adjustment (1) 0.9 % - 32.2 % ABS 23 Discounted cash flow Liquidity/duration adjustment (1) 3.0 % - 3.0 % Foreign government bonds 77 Discounted cash flow Liquidity/duration adjustment (1) 1.0 % - 2.7 % Hybrid and redeemable preferred securities 4 Discounted cash flow Liquidity/duration adjustment (1) 1.6 % - 1.6 % Equity securities 21 Discounted cash flow Liquidity/duration adjustment (1) 4.5 % - 5.2 % Other assets – GLB ceded embedded derivatives 111 Discounted cash flow Long-term lapse rate (2) 1 % - 30 % Utilization of guaranteed withdrawals (3) 85 % - 100 % Claims utilization factor (4) 60 % - 100 % Premiums utilization factor (4) 80 % - 115 % NPR (5) 0.02 % - 0.27 % Mortality rate (6) (8) Volatility (7) 1 % - 28 % Indexed annuity ceded embedded derivatives 903 Discounted cash flow Lapse rate (2) 1 % - 9 % Mortality rate (6) (8) Liabilities Future contract benefits – indexed annuity and IUL contracts embedded derivatives $ ( 1,973 ) Discounted cash flow Lapse rate (2) 1 % - 9 % Mortality rate (6) (8) Other liabilities – GLB direct embedded derivatives ( 1 ) Discounted cash flow Long-term lapse rate (2) 1 % - 30 % Utilization of guaranteed withdrawals (3) 85 % - 100 % Claims utilization factor (4) 60 % - 100 % Premiums utilization factor (4) 80 % - 115 % NPR (5) 0.02 % - 0.27 % Mortality rate (6) (8) Volatility (7) 1 % - 28 % (1) 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. (2) 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 and IUL contracts represents the lapse rates during the surrender charge period. (3) The utilization of guaranteed withdrawals input represents the estimated percentage of contract holders that utilize the guaranteed withdrawal feature. (4) 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. (5) The NPR input represents the estimated additional credit spread that market participants would apply to the market observable discount rate when pricing a contract. (6) 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. (7) 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. (8) The mortality rate is based on a combination of company and industry experience, adjusted for improvement factors. 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 may result 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 result in a decrease in the fair value measurement.  Indexed annuity and IUL contracts embedded derivatives – For direct embedded derivatives, an increase in the lapse rate or mortality rate inputs would result in a decrease in the fair value measurement.  GLB embedded derivatives – Assuming our GLB direct embedded derivatives are in a liability position: an increase in our lapse rate, NPR or mortality rate inputs would result in a decrease in the fair value measurement; and an increase in the utilization of guaranteed withdrawal or volatility inputs would result 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 will not affect 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.

Segment Information [Abstract]
Segment Information	14. Segment Information We provide products and services and report results through our Annuities, Retirement Plan Services, Life Insurance and Group Protection segments. As discussed in Note 3, we completed the acquisition of Liberty Life during the second quarter of 2018. Related results are included within the Group Protection segment. We also have Other Operations, which includes the financial data for operations that are not directly related to the business segments. Our reporting segments reflect the manner by which our chief operating decision makers view and manage the business. A discussion of these segments and Other Operations is found in Note 21 of our 2018 Form 10-K. Segment operating revenues and income (loss) from operations are internal measures used by our management and Board of Directors to evaluate and assess the results of our segments. Income (loss) from operations is GAAP net income excluding the after-tax effects of the following items, as applicable:  Realized gains and losses associated with the following (“excluded realized gain (loss)”):  Sales or disposals and impairments of securities;  Changes in the fair value of derivatives, embedded derivatives within certain reinsurance arrangements and trading securities (“gain (loss) on the mark-to-market on certain instruments”);  Changes in the fair value of the derivatives we own to hedge our GDB riders reflected within our variable annuities;  Changes in the fair value of the embedded derivatives of our GLB riders reflected within variable annuity net derivative results accounted for at fair value;  Changes in the fair value of the derivatives we own to hedge our GLB riders reflected within variable annuity net derivative results;  Changes in the fair value of the embedded derivative liabilities related to index call options we may purchase in the future to hedge contract holder index allocations applicable to future reset periods for our indexed annuity products accounted for at fair value (“indexed annuity forward-starting option”); and  Changes in the fair value of equity securities;  Changes in reserves resulting from benefit ratio unlocking on our GDB and GLB riders (“benefit ratio unlocking”);  Income (loss) from reserve changes, net of related amortization, on business sold through reinsurance;  Gains (losses) on early extinguishment of debt;  Losses from the impairment of intangible assets;  Income (loss) from discontinued operations;  Acquisition and integration costs related to mergers and acquisitions; and  Income (loss) from the initial adoption of new accounting standards, regulations, and policy changes including the net impact from the Tax Cuts and Jobs Act. Operating revenues represent GAAP revenues excluding the pre-tax effects of the following items, as applicable:  Excluded realized gain (loss);  Revenue adjustments from the initial adoption of new accounting standards;  Amortization of DFEL arising from changes in GDB and GLB benefit ratio unlocking; and  Amortization of deferred gains arising from reserve changes on business sold through reinsurance.

Subsequent Events [Abstract]
Subsequent Events	15. Subsequent Event On July 31, 2019, we entered into a credit agreement with a syndicate of banks. This agreement (the “credit facility”) allows for the issuance of letters of credit and borrowing of up to $ 2.25 billion. The credit facility is unsecured and has a commitment termination date of July 31, 2024. Under the credit facility, we pay a fee of 0.875 % per annum on issued syndicated letters of credit and a facility fee of 0.125 % per annum on the aggregate commitment. These fees adjust automatically in the event of a change in our credit ratings. Effective as of July 31, 2019, the credit facility replaced our credit agreement dated as of June 30, 2016, and the commitments under that agreement have been terminated.

Nature Of Operations And Basis Of Presentation
Nature Of Operations	Nature of Operations Lincoln National Corporation and its majority-owned subsidiaries (“LNC” or the “Company,” which also may be referred to as “we,” “our” or “us”) operate multiple insurance businesses through four business segments. See Note 14 for additional details. The collective group of businesses uses “Lincoln Financial Group” as its marketing identity. Through our business segments, we sell a wide range of wealth protection, accumulation and retirement income 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, indexed universal life insurance (“IUL”), term life insurance, employer-sponsored retirement plans and services, and group life, disability and dental.
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. As discussed in Note 3, on May 1, 2018, LNC and The Lincoln National Life Insurance Company (“LNL”) completed the acquisition of Liberty Life Assurance Company of Boston (“Liberty Life”). 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, 2018 (“2018 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 2018 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 six months ended June 30, 2019, are not necessarily indicative of the results that may be expected for the full year ending December 31, 2019. All material inter-company accounts and transactions have been eliminated in consolidation.

See Note 3 for additional information. (2) 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.

(2) 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 and IUL contracts represents the lapse rates during the surrender charge period. (3) The utilization of guaranteed withdrawals input represents the estimated percentage of contract holders that utilize the guaranteed withdrawal feature. (4) 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. (5) The NPR input represents the estimated additional credit spread that market participants would apply to the market observable discount rate when pricing a contract. (6) 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. (7) 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. (8) The mortality rate is based on a combination of company and industry experience, adjusted for improvement factors.
