Accounting Policies [Abstract]
Basis of Presentation	1. Basis of Presentation Loews Corporation is a holding company. Its subsidiaries are engaged in the following lines of business: commercial property and casualty insurance (CNA Financial Corporation (“CNA”), an 89% owned subsidiary); the operation of offshore oil and gas drilling rigs (Diamond Offshore Drilling, Inc. (“Diamond Offshore”), a 53% owned subsidiary); transportation and storage of natural gas and natural gas liquids (Boardwalk Pipeline Partners, LP (“Boardwalk Pipelines”), a wholly owned subsidiary); the operation of a chain of hotels (Loews Hotels Holding Corporation (“Loews Hotels & Co”), a wholly owned subsidiary); and the manufacture of rigid plastic packaging solutions (Consolidated Container Company LLC (“Consolidated Container”), a 99% owned subsidiary). Unless the context otherwise requires, the terms “Company,” “Loews” and “Registrant” as used herein mean Loews Corporation excluding its subsidiaries and the term “Net income attributable to Loews Corporation” as used herein means Net income attributable to Loews Corporation shareholders. In the opinion of management, the accompanying unaudited Consolidated Condensed Financial Statements reflect all adjustments (consisting of normal recurring accruals) necessary to present fairly the Company’s financial position as of September 30, 2019 and December 31, 2018 and results of operations, comprehensive income and changes in shareholders’ equity for the three and nine months ended September 30, 2019 and 2018 and cash flows for the nine months ended September 30, 2019 and 2018. Net income for the third quarter and first nine months of each of the years is not necessarily indicative of net income for that entire year. These Consolidated Condensed Financial Statements should be read in conjunction with the Consolidated Financial Statements in the Company’s Annual Report on Form 10-K The Company presents basic and diluted net income per share on the Consolidated Condensed Statements of Income. Basic net income per share excludes dilution and is computed by dividing net income attributable to common stock by the weighted average number of common shares outstanding for the period. Diluted net income per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock. There were no shares attributable to employee stock-based compensation awards excluded from the diluted weighted average shares outstanding amounts for the three and nine months ended September 30, 2019 and 2018 because the effect would have been antidilutive. Accounting changes 2016-02, 2016-02”). For leases where we are a lessee we have elected to account for lease and non-lease non-lease At adoption, the cumulative effect adjustment increased Other assets and Other liabilities by $642 million reflecting operating lease right of use assets, lease liabilities and the derecognition of deferred rent related primarily to lease agreements for office space and machinery and equipment. Subsequent to the adoption of ASU 2016-02, Recently issued ASUs 2016-13, mortgage loans, reinsurance and insurance receivables and other financing receivables and the use of the allowance method rather than the write-down method for credit losses within the available-for-sale available-for-sale The Company is currently in the process of evaluating existing impairment methodology, developing models to comply with the new guidance and accumulating the necessary internal and external information required to measure credit losses under the expected credit loss model. The Company is implementing changes to the information systems to assist with the accounting, including the recording of the allowance. The Company is also evaluating additional changes to processes to meet the reporting and disclosure requirements of the new guidance. In August of 2018, the FASB issued ASU 2018-12, This guidance is effective for interim and annual periods beginning after December 15, 2020; however, the FASB has approved are

The Company has no current intent to sell securities with unrealized losses, nor is it more likely than not that it will be required to sell prior to recovery of amortized cost; accordingly, the Company has determined that there are no additional OTTI losses to be recorded as of September 30, 2019. The following table presents the activity related to the pretax credit loss component reflected in Retained earnings on fixed maturity securities still held as of September 30, 2019 and 2018 for which a portion of an OTTI loss was recognized in OCI.

Fair Value

Fair Value Disclosures [Abstract]
Fair Value	4. Fair Value Fair value is the price that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The following fair value hierarchy is used in selecting inputs, with the highest priority given to Level 1, as these are the most transparent or reliable: • Level 1 – Quoted prices for identical instruments in active markets. • Level 2 – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs are observable in active markets. • Level 3 – Valuations derived from valuation techniques in which one or more significant inputs are not observable. Prices may fall within Level 1, 2 or 3 depending upon the methodology and inputs used to estimate fair value for each specific security. In general, the Company seeks to price securities using third party pricing services. Securities not priced by pricing services are submitted to independent brokers for valuation and, if those are not available, internally developed pricing models are used to value assets using a methodology and inputs the Company believes market participants would use to value the assets. Prices obtained from third-party pricing services or brokers are not adjusted by the Company. The Company performs control procedures over information obtained from pricing services and brokers to ensure prices received represent a reasonable estimate of fair value and to confirm representations regarding whether inputs are observable or unobservable. Procedures may include: (i) the review of pricing service methodologies or broker pricing qualifications, (ii) back-testing, where past fair value estimates are compared to actual transactions executed in the market on similar dates, (iii) exception reporting, where period-over-period changes in price are reviewed and challenged with the pricing service or broker based on exception criteria, (iv) detailed analysis, where the Company performs an independent analysis of the inputs and assumptions used to price individual securities and (v) pricing validation, where prices received are compared to prices independently estimated by the Company. Assets and liabilities measured at fair value on a recurring basis are summarized in the following tables.

The availability of observable market information and quoted prices varies based on market conditions and trading volume. Valuation Methodologies and Inputs The following section describes the valuation methodologies and relevant inputs used to measure different financial instruments at fair value, including an indication of the level in the fair value hierarchy in which the instruments are generally classified. Fixed Maturity Securities Level 1 securities include highly liquid and exchange traded bonds, valued using quoted market prices. Level 2 securities include most other fixed maturity securities as the significant inputs are observable in the marketplace. All classes of Level 2 fixed maturity securities are valued using a methodology based on information generated by market transactions involving identical or comparable assets, a discounted cash flow methodology or a combination of both when necessary. Common inputs for all classes of fixed maturity securities include prices from recently executed transactions of similar securities, marketplace quotes, benchmark yields, spreads off benchmark yields, interest rates and U.S. Treasury or swap curves. Specifically for asset-backed securities, key inputs include prepayment and default projections based on past performance of the underlying collateral and current market data. Fixed maturity securities are primarily assigned to Level 3 in cases where broker/dealer quotes are significant inputs to the valuation, and there is a lack of transparency as to whether these quotes are based on information that is observable in the marketplace. Level 3 securities also include private placement debt securities whose fair value is determined using internal models with inputs that are not market observable. Equity Securities Level 1 securities include publicly traded securities valued using quoted market prices. Level 2 securities are primarily valued using pricing for similar securities, recently executed transactions and other pricing models utilizing market observable inputs. Level 3 securities are primarily priced using broker/dealer quotes and internal models with inputs that are not market observable. Derivative Financial Instruments Exchange traded derivatives are valued using quoted market prices and are classified within Level 1 of the fair value hierarchy. Level 2 derivatives primarily include currency forwards valued using observable market forward rates. Over-the-counter Short Term and Other Invested Assets Securities that are actively traded or have quoted prices are classified as Level 1. These securities include money market funds, treasury bills and exchange traded open-end Significant Unobservable Inputs The following tables present quantitative information about the significant unobservable inputs utilized by the Company in the fair value measurement of Level 3 assets. Valuations for assets and liabilities not presented in the tables below are primarily based on broker/dealer quotes for which there is a lack of transparency as to inputs used to develop the valuations. The quantitative detail of unobservable inputs from these broker quotes is neither provided nor reasonably available to the Company. The weighted average rate is calculated based on fair value. September 30, 2019 Estimated Valuation Unobservable Range (In millions) Fixed maturity securities $ 496 Discounted cash flow Credit spread 1% – December 31, 2018 Fixed maturity securities $ 228 Discounted cash flow Credit spread 1% – 12% (3%) For fixed maturity securities, an increase to the credit spread assumptions would result in a lower fair value measurement. Financial Assets and Liabilities Not Measured at Fair Value The carrying amount, estimated fair value and the level of the fair value hierarchy of the Company’s financial assets and liabilities which are not measured at fair value on the Consolidated Condensed Balance Sheets are presented in the following tables. The carrying amounts and estimated fair values of short term debt and long term debt exclude capital lease obligations. The carrying amounts reported on the Consolidated Condensed Balance Sheets for cash and short term investments not carried at fair value and certain other assets and liabilities approximate fair value due to the short term nature of these items. Carrying Estimated Fair Value September 30, 2019 Amount Level 1 Level 2 Level 3 Total (In millions) Assets: Other invested assets, primarily mortgage loans $ 923 $ 950 $ 950 Liabilities: Short term debt 85 $ 9 76 85 Long term debt 11,383 10,638 595 11,233 December 31, 2018 Assets: Other invested assets, primarily mortgage loans $ 839 $ 827 $ 827 Liabilities: Short term debt 15 $ 14 14 Long term debt 11,345 10,111 653 10,764 The fair values of mortgage loans, included in Other invested assets, were based on the present value of the expected future cash flows discounted at the current interest rate for similar financial instruments, adjusted for specific loan risk.

Claim and Claim Adjustment Expe

Claim and Claim Adjustment Expense Reserves	9 Months Ended

Insurance [Abstract]
Claim and Claim Adjustment Expense Reserves	5. Claim and Claim Adjustment Expense Reserves CNA’s property and casualty insurance claim and claim adjustment expense reserves represent the estimated amounts necessary to resolve all outstanding claims, including incurred but not reported (“IBNR”) claims as of the reporting date. CNA’s reserve projections are based primarily on detailed analysis of the facts in each case, CNA’s experience with similar cases and various historical development patterns. Consideration is given to historical patterns such as claim reserving trends and settlement practices, loss payments, pending levels of unpaid claims and product mix, as well as court decisions and economic conditions, including inflation and public attitudes. All of these factors can affect the estimation of claim and claim adjustment expense reserves. Establishing claim and claim adjustment expense reserves, including claim and claim adjustment expense reserves for catastrophic events that have occurred, is an estimation process. Many factors can ultimately affect the final settlement of a claim and, therefore, the necessary reserve. Changes in the law, results of litigation, medical costs, the cost of repair materials and labor rates can affect ultimate claim costs. In addition, time can be a critical part of reserving determinations since the longer the span between the incidence of a loss and the payment or settlement of the claim, the more variable the ultimate settlement amount can be. Accordingly, short-tail claims, such as property damage claims, tend to be more reasonably estimable than long-tail claims, such as workers’ compensation, general liability and professional liability claims. Adjustments to prior year reserve estimates, if necessary, are reflected in the results of operations in the period that the need for such adjustments is determined. There can be no assurance that CNA’s ultimate cost for insurance losses will not exceed current estimates. Catastrophes are an inherent risk of the property and casualty insurance business and have contributed to material period-to-period an d 2018 Liability for Unpaid Claim and Claim Adjustment Expenses The following table presents a reconciliation between beginning and ending claim and claim adjustment expense reserves, including claim and claim adjustment expense reserves of Other Insurance Operations. Nine Months Ended September 30 2019 2018 (In millions) Reserves, beginning of year: Gross $ 21,984 $ 22,004 Ceded 4,019 3,934 Net reserves, beginning of year 17,965 18,070 Net incurred claim and claim adjustment expenses: Provision for insured events of current year 3,968 3,866 Increase (decrease) in provision for insured events of prior years (65 ) (173 ) Amortization of discount 143 136 Total net incurred (a) 4,046 3,829 Net payments attributable to: Current year events (599 ) (658 ) Prior year events (3,547 ) (3,415 ) Total net payments (4,146 ) (4,073 ) Foreign currency translation adjustment and other 29 (80 ) Net reserves, end of period 17,894 17,746 Ceded reserves, end of period 3,702 3,858 Gross reserves, end of period $ 21,596 $ 21,604 (a) Total net incurred above does not agree to Insurance claims and policyholders’ benefits as reflected on the Consolidated Condensed Statements of Income due to amounts related to retroactive reinsurance deferred gain accounting, uncollectible reinsurance and loss deductible receivables and benefit expenses related to future policy benefits, which are not reflected in the table above. Net Prior Year Development Changes in estimates of claim and claim adjustment expense reserves net of reinsurance, for prior years are defined as net prior year loss reserve development. These changes can be favorable or unfavorable. CNA’s commercial property and casualty operations (“Property & Casualty Operations”) recorded unfavorable net prior year development of and fav orable net prior year development of September 30, 2019 and 2018, and favorable net prior year development of $ million and $ million for the nine months ended September 30, 2019 and 2018 . The following table and discussion present details of the net prior year claim and claim adjustment expense reserve development in CNA’s Property & Casualty Operations: Three Months Ended Nine Months Ended September 30, September 30, 2019 2018 2019 2018 (In millions) Medical professional liability $ 29 $ 15 $ 59 $ 38 Other professional liability and management liability (18 ) (45 ) (37 ) (113 ) Surety (43 ) (20 ) (83 ) (50 ) Commercial auto (16 ) 1 (24 ) General liability 43 (5 ) 36 13 Workers’ compensation 7 (2 ) 2 (14 ) Other 14 (6 ) 18 (34 ) Total pretax (favorable) unfavorable development $ 16 $ (62 ) $ (29 ) $ (160 ) Three Months 2019 Unfavorable development in medical professional liability was primarily due to higher than expected indemnity severity in accident years 2016 through 2018 in CNA’s aging services business. Favorable development in other professional liability and management liability was due to lower than expected large claim losses in recent accident years in CNA’s public company directors and officers liability (“D&O”) business. Favorable development in surety was due to lower than expected frequency for accident years 2015 through 2018. Favorable development in commercial auto was primarily due to a decline in bodily injury frequency in accident year 2018 and continued lower than expected severity across accident years 2013 through 2016. Unfavorable development in general liability was primarily due to higher than expected emergence in mass tort related to accident years 2009 and prior, 2015 and 2016. Unfavorable development in other was primarily due to higher than expected severity in aging services related to auto liability coverages. 2018 Unfavorable development in medical professional liability was primarily driven by higher than expected frequency and severity in aging services in accident years 2014 through 2017. Favorable development in other professional liability and management liability was primarily driven by favorable outcomes on individual claims in accident years 2013 and prior in financial institutions. Favorable development in surety was due to continued lower than expected loss emergence for accident years 2017 and prior. Nine Months 2019 Unfavorable development in medical professional liability was primarily due to higher than expected indemnity severity in accident years 2016 through 2018 in CNA’s aging services business, higher than expected severity in accident year 2013 in CNA’s allied healthcare business, unfavorable outcomes on individual claims and higher than expected severity in accident year 2017 in CNA’s dentists business. Favorable development in other professional liability and management liability was primarily due to lower than expected claim frequency and favorable outcomes on individual claims in accident years 2017 and prior related to financial institutions and lower than expected large claim losses in recent accident years in CNA’s public company D&O business. Favorable development in surety was due to lower than expected frequency for accident years 2018 and prior. Favorable development in commercial auto was primarily due to a decline in bodily injury frequency in accident year 2018 and continued lower than expected severity across accident years 2016 and prior. Unfavorable development in general liability was primarily due to higher than expected emergence in mass tort as well as higher than expected large loss experience in CNA’s excess and umbrella business in accident year 2017. Unfavorable development in other was primarily due to higher than expected severity in aging services related to auto liability coverages and higher than expected claims in Hardy on 2018 accident year catastrophes in property partially offset by favorable development in casualty driven by lower than expected large losses and claim severity in accident years 2014 and prior in Hardy and Europe. 2018 Unfavorable development in Favorable development in other professional liability and management liability was primarily due to lower than expected claim frequency for accident years 2013 through 2017 related to financial institutions and professional liability errors and omissions (“E&O”) , Favorable development in Favorable development for other coverages was due to lower than expected claim severity in catastrophes in accident year 2017 for property, better than expected frequency in the liability portion of the package business in Canada and general liability in Europe for casualty, better than expected large loss frequency in the energy book in recent accident years for energy and marine and lower than expected frequency in accident years 2015 and prior related to healthcare in Europe for healthcare and technology. This favorable development was partially offset by unfavorable development driven by higher than expected severity in Canada and higher than expected frequency in Hardy, both in accident year 2017, for property and increased severity in accident year 2017 related to professional indemnity. Asbestos and Environmental Pollution (“A&EP”) Reserves In 2010, Continental Casualty Company (“CCC”) together with several of CNA’s insurance subsidiaries completed a transaction with National Indemnity Company (“NICO”), a subsidiary of Berkshire Hathaway Inc., under which substantially all of CNA’s legacy A&EP liabilities were ceded to NICO through a loss portfolio transfer (“loss portfolio transfer” or “LPT”). At the effective date of the transaction, CNA ceded approximately $1.6 billion of net A&EP claim and allocated claim adjustment expense reserves to NICO under a retroactive reinsurance agreement with an aggregate limit of $4.0 billion. The $1.6 billion of claim and allocated claim adjustment expense reserves ceded to NICO was net of $1.2 billion of ceded claim and allocated claim adjustment expense reserves under existing third party reinsurance contracts. The NICO LPT aggregate reinsurance limit also covers credit risk on the existing third party reinsurance related to these liabilities. CNA paid NICO a reinsurance premium of $2.0 billion and transferred to NICO billed third party reinsurance receivables related to A&EP claims with a net book value of $215 million, resulting in total consideration of $2.2 billion. In years subsequent to the effective date of the LPT, CNA recognized adverse prior year development on its A&EP reserves resulting in additional amounts ceded under the LPT. As a result, the cumulative amounts ceded under the LPT have exceeded the $2.2 billion consideration paid, resulting in the NICO LPT moving into a gain position, requiring retroactive reinsurance accounting. Under retroactive reinsurance accounting, this gain is deferred and only recognized in earnings in proportion to actual paid recoveries under the LPT. Over the life of the contract, there is no economic impact as long as any additional losses incurred are within the limit of the LPT. In a period in which CNA recognizes a change in the estimate of A&EP reserves that increases or decreases the amounts ceded under the LPT, the proportion of actual paid recoveries to total ceded losses is affected and the change in the deferred gain is recognized in earnings as if the revised estimate of ceded losses was available at the effective date of the LPT. The effect of the deferred retroactive reinsurance benefit is recorded in Insurance claims and policyholders’ benefits on the Consolidated Condensed Statements of Income. The following table presents the impact of the loss portfolio transfer on the Consolidated Condensed Statements of Income. Three Months Ended Nine Months Ended September 30, September 30, 2019 2018 2019 2018 (In millions) Additional amounts ceded under LPT: Net A&EP adverse development before consideration of LPT $ 113 Provision for uncollectible third-party reinsurance on A&EP (16 ) Total additional amounts ceded under LPT $ - $ - $ - 97 Retroactive reinsurance benefit recognized (7 ) (12 ) (43 ) (84 ) Pretax impact of deferred retroactive reinsurance $ (7 ) $ (12 ) $ (43 ) $ 13 CNA intends to complete its annual A&EP reserve review in the fourth quarter of 2019 and maintain this timing for all future annual A&EP reserve reviews. CNA completed A&EP reserve reviews in both the first and fourth quarters of 2018. Based upon CNA’s 2018 first quarter A&EP reserve review, net unfavorable prior year development of $113 million was recognized before consideration of cessions to the LPT for the nine months ended September 30, 2018. The 2018 unfavorable development was driven by higher than anticipated defense costs on direct asbestos and environmental accounts and paid losses on assumed reinsurance exposures. Additionally, in 2018, CNA released a portion of its provision for uncollectible third party reinsurance. As of September 30, 2019 and December 31, 2018, the cumulative amounts ceded under the LPT were $3.1 billion. The unrecognized deferred retroactive reinsurance benefit was $331 million and $374 million as of September 30, 2019 and December 31, 2018 and is included within Other liabilities on the Consolidated Condensed Balance Sheets. NICO established a collateral trust account as security for its obligations to CNA. The fair value of the collateral trust account was $3.3 billion and $2.7 billion as of September 30, 2019 and December 31, 2018. In addition, Berkshire Hathaway Inc. guaranteed the payment obligations of NICO up to the aggregate reinsurance limit as well as certain of NICO’s performance obligations under the trust agreement. NICO is responsible for claims handling and billing and collection from third-party reinsurers related to the majority of CNA’s A&EP claims. Long Term Care Policyholder Reserves CNA’s operations include its run-off long term care business as well as structured settlement obligations not funded by annuities related to certain property and casualty claimants. Long term care policies provide benefits for nursing homes, assisted living facilities and home health care subject to various daily and lifetime caps. Generally, policyholders must continue to make periodic premium payments to keep the policy in force and CNA has the ability to increase policy premiums, subject to state regulatory approval. CNA maintains both claim and claim adjustment expense reserves as well as future policy benefit reserves for policyholder benefits for its long term care business. Claim and claim adjustment expense reserves consist of estimated reserves for long term care policyholders that are currently receiving benefits, including claims that have been incurred but are not yet reported. In developing the claim and claim adjustment expense reserve estimates for long term care policies, CNA’s actuaries perform a detailed claim experience study on an annual basis. The study reviews the sufficiency of existing reserves for policyholders currently on claim and includes an evaluation of expected benefit utilization and claim duration. CNA’s recorded claim and claim adjustment expense reserves reflect management’s best estimate after incorporating the results of the most recent study. In addition, claim and claim adjustment expense reserves are also maintained for the structured settlement obligations. CNA’s most recent annual long term care claim experience study was completed in the third quarter of 2019 and resulted in a $56 million pretax reduction in claim and claim adjustment expense reserves primarily due to lower claim severity than anticipated in the reserve estimates. CNA’s 2018 annual long term care claim experience study was completed in the third quarter of 2018 and resulted in a $31 million pretax reduction in claim and claim adjustment expense reserves. Future policy benefit reserves represent the active life reserves related to CNA’s long term care policies which are the present value of expected future benefit payments and expenses less expected future premium. The determination of these reserves is fundamental to CNA’s financial results and requires management to make estimates and assumptions about expected investment and policyholder experience over the life of the contract. Since many of these contracts may be in force for several decades, these assumptions are subject to significant estimation risk. The actuarial assumptions that management believes are subject to the most variability are morbidity, persistency, discount rate and anticipated future premium rate increases. Morbidity is the frequency and severity of injury, illness, sickness and diseases contracted. Persistency is the percentage of policies remaining in force and can be affected by policy lapses, benefit reductions and death. Discount rate is influenced by the investment yield on assets supporting long term care reserves which is subject to interest rate and market volatility and may also be affected by changes to the Internal Revenue Code. As future premium rate increases are generally subject to regulatory approval, the exact timing and size of the approved rate increases are unknown. As a result of this variability, CNA’s long term care reserves may be subject to material increases if actual experience develops adversely to CNA’s expectations. Annually, management assesses the adequacy of its long term care future policy benefit reserves by performing a gross premium valuation (“GPV”) to determine if there is a premium deficiency. Management also uses the GPV process to evaluate the adequacy of its claim and claim adjustment expense reserves for structured settlement obligations. Under the GPV, management estimates required reserves using best estimate assumptions as of the date of the assessment without provisions for adverse deviation. The GPV required reserves are then compared to the existing recorded reserves. If the GPV required reserves are greater than the existing recorded reserves, the existing assumptions are unlocked and future policy benefit reserves are increased to the greater amount. Any such increase is reflected in the Company’s results of operations in the period in which the need for such adjustment is determined. Periodically, management engages independent third parties to assess the appropriateness of its best estimate assumptions. The most recent third party assessment, performed earlier this year, validated the assumption setting process and confirmed the best estimate assumptions appropriately reflected the experience data at that time. In the third quarter of 2019, CNA performed the GPV for the long term care future policy benefit reserves. This GPV indicated a premium deficiency primarily driven by lower discount rate assumptions. Recognition of the premium deficiency resulted in a $216 million pretax increase in policyholders’ benefits reflected in the Company’s results of operations.

Leases [Abstract]
Leases	6. Leases The Company’s lease agreements primarily cover office facilities and machinery and equipment and expire at various dates. The Company’s leases are predominantly operating leases, which are included in Other assets and Other liabilities on the Consolidated Condensed Balance Sheet. The Company’s lease agreements do not contain significant residual value guarantees, restrictions or covenants. Operating lease right of use assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. The discount rate used to determine the commencement date present value of lease payments is the interest rate implicit in the lease, or when that is not readily determinable, the Company utilizes its incremental borrowing rate. The Company’s operating lease right of use asset was $612 million and the Company’s operating lease liability was $694 million at September 30, 2019. Operating lease cost was $31 million and $90 million, variable lease cost was $5 million and $14 million and short term lease cost was $1 million and $5 million for the three and nine months ended September 30, 2019. Cash paid for amounts included in operating lease liabilities was $28 million and $87 million for the three and nine months ended September 30, 2019.

Legal Proceedings	11. Legal Proceedings On May 25, 2018, plaintiffs Tsemach Mishal and Paul Berger (on behalf of themselves and the purported class, “Plaintiffs”) initiated a purported class action in the Court of Chancery of the State of Delaware (the “Court”) against the following defendants: Boardwalk Pipelines, Boardwalk GP, LP (“General Partner”), Boardwalk GP, LLC and Boardwalk Pipelines Holding Corp. (“BPHC”) (together, “Defendants”), regarding the potential exercise by the General Partner of its right to purchase all of the issued and outstanding common units representing limited partnership interests in Boardwalk Pipelines not already owned by the General Partner or its affiliates. On June 25, 2018, Plaintiffs and Defendants entered into a Stipulation and Agreement of Compromise and Settlement, subject to the approval of the Court (the “Proposed Settlement”). Under the terms of the Proposed Settlement, the lawsuit would be dismissed, and related claims against the Defendants would be released by the Plaintiffs, if BPHC, the sole member of the General Partner, elected to cause the General Partner to exercise its right to purchase the issued and outstanding common units of Boardwalk Pipelines pursuant to Boardwalk Pipelines’ Third Amended and Restated Agreement of Limited Partnership, as amended (“Limited Partnership Agreement”), within a period specified by the Proposed Settlement. On June 29, 2018, the General Partner elected to exercise its right to purchase all of the issued and outstanding common units representing limited partnership interests in Boardwalk Pipelines not already owned by the General Partner or its affiliates pursuant to the Limited Partnership Agreement within the period specified by the Proposed Settlement. The transaction was completed on July 18, 2018 . On September 28, 2018, the Court denied approval of the Proposed Settlement. On February 11, 2019, a substitute verified class action complaint was filed in this proceeding. The Defendants filed a motion to dismiss, which was heard by the Court in July of 2019. In October of 2019, the Court ruled on the motion and granted a partial dismissal, with certain aspects of the case proceeding to trial. The case will be set for trial in early 2021. The Company and its subsidiaries are from time to time parties to other litigation arising in the ordinary course of business. While it is difficult to predict the outcome or effect of any such litigation, management does not believe that the outcome of any such pending litigation will materially affect the Company’s results of operations or equity.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	12. Commitments and Contingencies CNA Guarantees In the course of selling business entities and assets to third parties, CNA indemnified purchasers for certain losses, some of which are not limited by a contractual monetary amount. As of September 30, 2019, CNA had outstanding unlimited indemnifications that included tax liabilities arising prior to a purchaser’s ownership of an entity or asset, defects in title at the time of sale, employee claims arising prior to closing and in some cases losses arising from certain litigation and undisclosed liabilities. Certain provisions of the indemnification agreements survive indefinitely while others survive until the applicable statutes of limitation expire, or until the agreed upon contract terms expire. CNA also provided guarantees, if the primary obligor fails to perform, to holders of structured settlement annuities provided by a previously owned subsidiary. As of September 30, 2019, the potential amount of future payments CNA could be required to pay under these guarantees was approximately $1.7 billion, which will be paid over the lifetime of the annuitants. CNA does not believe any payment is likely under these guarantees, as CNA is the beneficiary of a trust that must be maintained at a level that approximates the discounted reserves for these annuities.
