Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	1. BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES The Hartford Insurance Group, Inc. ("HIG") is a holding company for insurance and financial services subsidiaries that provide property and casualty ("P&C") insurance, employee group benefits insurance and services and mutual funds and exchange-traded funds ("ETF") to individual and business customers in the United States as well as in the United Kingdom and other international locations (collectively, “The Hartford”, the “Company”, “we” or “our”). Previously known as The Hartford Financial Services Group, Inc., the Company changed its name to The Hartford Insurance Group, Inc. on February 6, 2025. The Hartford conducts business principally in five reportable segments including Business Insurance (formerly "Commercial Lines"), Personal Insurance (formerly "Personal Lines"), Property & Casualty Other Operations, Employee Benefits (formerly "Group Benefits") and Hartford Funds, as well as a Corporate category. The Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) which differ materially from the accounting practices prescribed by various insurance regulatory authorities. Consolidation The Consolidated Financial Statements include the accounts of The Hartford Insurance Group, Inc., and entities in which the Company directly or indirectly has a controlling financial interest. Entities in which the Company has significant influence over the operating and financing decisions but does not control are reported using the equity method. Intercompany transactions and balances between The Hartford and its subsidiaries and affiliates have been eliminated. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The most significant estimates include those used in determining property and casualty and group long-term disability ("LTD") insurance product reserves, net of reinsurance; evaluation of goodwill for impairment; valuation of investments and derivative instruments; and contingencies relating to corporate litigation and regulatory matters. Adoption of New Accounting Standards Segment Disclosures On December 31, 2024, the Company adopted the Financial Accounting Standards Board’s (“FASB”) new guidance on Segment Reporting, that was applied on a retrospective basis for all periods presented. The new guidance requires enhanced disclosures on an annual and quarterly basis about significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”) and included within the reported measure of segment profit or loss, as well as disclosure of the title and position of the CODM and a description of how the reported measure of profit or loss is used to assess segment performance and allocate resources. The Company has included the new disclosures in Note 3 - Segment Information of Notes to Consolidated Financial Statements. The Company will also provide the quarterly disclosures beginning with the March 31, 2025 interim condensed consolidated financial statements. The new guidance did not have an impact on the consolidated financial position, results of operations, or cash flows. Future Adoption of New Accounting Standards Income Tax Disclosures The FASB issued new disclosure requirements for income taxes primarily for the income tax rate reconciliation and income taxes paid. The income tax rate reconciliation within the income taxes note will present reconciling items based on specified categories with further disaggregation of items above a prescribed threshold. Disclosure of income taxes paid (net of refunds received) in the consolidated statement of cash flows will be disaggregated by federal (national), state, and foreign taxes with further disaggregation by individual jurisdictions subject to a prescribed threshold. The Company is required to provide the new disclosure annually beginning with the December 31, 2025 consolidated financial statements. Disclosures are required to be provided on a prospective basis with retrospective application permitted. The Company is evaluating the disclosure impact of the new guidance; however, the new guidance will not have an impact on the consolidated financial position, results of operations, or cash flows. Disaggregated Income Statement Expenses The FASB issued new guidance on disclosures of disaggregated income statement expenses. The new guidance requires footnote disclosures that will disaggregate expenses included in relevant expense captions into prescribed categories, as well as narrative disclosures about selling expenses. The Company is required to provide the new disclosures beginning with the December 31, 2027 consolidated financial statements and on a quarterly basis beginning with the March 31, 2028 interim condensed consolidated financial statements. The new guidance will be applied on a prospective basis, with retrospective application or early adoption permitted. The Company is evaluating the disclosure impact of the new guidance; however, it will not have an impact on the consolidated financial position, results of operations, or cash flows. Significant Accounting Policies The Company’s significant accounting policies are as follows: Revenue Recognition Premium Revenue from Direct Insurance and Assumed Reinsurance Property and casualty premiums are earned on a pro rata basis over the policy period and include accruals for policies that have been written by agents but not yet reported to us, as well as ultimate premium revenue anticipated under auditable and retrospectively rated policies. We estimate the amount of premium not yet reported based on current and historical trends of the business being written. Such estimates are regularly reviewed and updated and any resulting adjustments are included in the current year's results. Unearned premiums represent the premiums applicable to the unexpired terms of policies in force, or period of risk. Group life, disability and accident premiums are generally due from policyholders, and recognized as revenue, on a pro rata basis over the period of the contracts. An estimated ACL is recorded on the basis of periodic evaluations of balances due from insureds and considering historical credit loss information, adjusted for current economic conditions as well as reasonable and supportable forecasts when appropriate. The Company records total credit loss expenses related to premiums receivable in insurance operating costs and other expenses. Write-offs of premiums receivable and agents' balances and any related ACL are recorded in the period in which the balance is deemed uncollectible. Refer to Note 7 - Premiums Receivable and Agents' Balances for further discussion regarding the allowance for doubtful accounts included in premiums receivable and agents’ balances. Non-Insurance Revenue from Contracts with Customers Installment fees are charged on property and casualty insurance contracts for billing the insurance customer in installments over the policy term. These fees are recognized in fee income as earned on collection. Insurance servicing revenues within Personal Insurance consist of up-front commissions earned for collecting premiums and processing claims on insurance policies for which The Hartford does not assume underwriting risk, predominantly related to the National Flood Insurance Plan program. These insurance servicing revenues are recognized in other revenues over the period of the flood program's policy terms. Employee Benefits earns fee income from employers for the administration of underwriting, implementation and claims processing for employer self-funded plans and for leave management services. Fees are recognized as services are provided and collected monthly. Hartford Funds provides investment management, administrative and distribution services to mutual funds and exchange-traded funds. The Company assesses investment advisory, distribution and other asset management fees primarily based on the average daily net asset values from mutual funds and exchange-traded funds, which are recorded in the period in which the services are provided and are collected monthly. Fluctuations in domestic and international markets and related investment performance, volume and mix of sales and redemptions of mutual funds or exchange-traded funds, and other changes to the composition of assets under management ("AUM") are all factors that ultimately have a direct effect on fee income earned. Corporate investment management and other fees are primarily for managing third party invested assets. These fees, calculated based on the average quarterly net asset values, are recorded in the period in which the services are provided and are collected quarterly. Fluctuations in markets and interest rates and other changes to the composition of assets under management are all factors that ultimately have a direct effect on fee income earned. Dividends to Policyholders Policyholder dividends are paid to certain property and casualty policyholders. Policies that receive dividends are referred to as participating policies. Participating dividends to policyholders are accrued and reported in insurance operating costs and other expenses and other liabilities using an estimate of the amount to be paid based on underlying contractual obligations under policies and applicable state laws. Net written premiums for participating property and casualty insurance policies represented 6%, 6%, and 7% of total net written premiums for each of the years ended December 31, 2024, 2023 and 2022, respectively. Participating dividends to property and casualty policyholders were $39, $39 and $29 for the years ended December 31, 2024, 2023 and 2022, respectively. There were no additional amounts of income allocated to participating policyholders. Investments Overview The Company’s investments in fixed maturities consist of bonds, including structured securities, and redeemable preferred stock. Most of these investments are classified as AFS and are carried at fair value. The after tax difference between fair value and cost or amortized cost is reflected in stockholders’ equity as a component of AOCI. Fixed maturities for which the Company elected the fair value option are classified as FVO and are carried at fair value with changes in value recorded in net realized gains and losses. These investments represent certain investments in residual interests of securitizations and other securities that contain embedded credit derivatives. Equity securities are measured at fair value with any changes in valuation reported in net realized gains and losses. Mortgage loans are recorded at the outstanding principal balance adjusted for amortization of premiums or discounts and net of an ACL. Short-term investments are carried at amortized cost, which approximates fair value. Limited partnerships and other alternative investments are reported at their carrying value and are primarily accounted for under the equity method with the Company’s share of earnings included in net investment income. Recognition of income related to limited partnerships and other alternative investments is delayed due to the availability of the related financial information, as private equity and other funds are generally received on a three-month delay. Accordingly, income for the years ended December 31, 2024, 2023, and 2022 may not include the full impact of current year changes in valuation of the underlying assets and liabilities of the funds, which are generally obtained from the limited partnerships. Other investments primarily consist of equity fund investments measured at fair value, overseas deposits which are measured at fair value using the net asset value as a practical expedient, consolidated investment funds for which the Company has provided seed money and reports the underlying investments at fair value with changes in the fair value recognized in income consistent with accounting requirements for investment companies, and derivative instruments which are carried at fair value. Net Realized Gains and Losses Net realized gains and losses from investment sales are reported as a component of revenues and are determined on a specific identification basis. Net realized gains and losses also result from fair value changes in equity securities, FVO securities, and derivatives contracts that do not qualify, or are not designated, as a hedge for accounting purposes. The Company records net credit losses on fixed maturities, AFS and changes in the ACL on mortgage loans as a component of net realized gains and losses. Future changes in the ACL resulting from improvements in expected future cash flows are recorded through net realized gains and losses. Net Investment Income Interest income from fixed maturities and mortgage loans is recognized when earned on the constant effective yield method based on the estimated timing of cash flows. Most premiums and discounts on fixed maturities are amortized to the maturity date. Premiums on callable bonds may be amortized to call dates based on call prices. For structured financial assets subject to prepayment risk, yields are recalculated and adjusted periodically to reflect historical and/or estimated future prepayments using the retrospective method. For certain other structured securities, including securities that previously had an ACL and interest only securities, any yield adjustments are made using the prospective method. Prepayment fees and make-whole payments on fixed maturities and mortgage loans are recorded in net investment income when earned. For equity securities, dividends are recognized as investment income on the ex-dividend date. Limited partnerships and other alternative investments primarily use the equity method of accounting to recognize the Company’s share of earnings. For fixed maturities with an ACL, net investment income is recognized at the original effective rate and accretion of the ACL is recognized through net realized gains and losses. The Company’s non-income producing investments were not material for the years ended December 31, 2024, 2023 and 2022. Accrued Investment Income Accrued investment income primarily includes accruals of interest and dividend income from investments that have been earned but not yet received. Derivative Instruments Overview The Company utilizes a variety of over-the-counter ("OTC") derivatives, derivatives cleared through central clearing houses ("OTC-cleared") and exchange traded derivative instruments as part of its overall risk management strategy as well as to engage in income generation covered call transactions and replication transactions. The types of instruments may include swaps, caps, floors, forwards, futures and options to achieve the following Company-approved objectives: •to hedge risk arising from interest rate, equity market, commodity market, credit spread and issuer default, price or currency exchange rates or volatility; •to manage liquidity; •to control transaction costs; and •to enter into income generation covered call transactions and synthetic replication transactions. Interest rate and credit default swaps involve the periodic exchange of cash flows with other parties, at specified intervals, calculated using agreed upon rates or other financial variables and notional principal amounts. Generally, little to no cash or principal payments are exchanged at the inception of the contract. Typically, at the time a swap is entered into, the cash flow streams exchanged by the counterparties are equal in value. The Company clears certain interest rate swap and credit default swap derivative transactions through central clearing houses. OTC-cleared derivatives require initial collateral at the inception of the trade in the form of cash or highly liquid securities, such as U.S. Treasuries and government agency investments. Central clearing houses also require additional cash as variation margin based on daily market value movements. For information on collateral, see the Derivative Collateral Arrangements section in Note 6 - Derivatives. In addition, OTC-cleared transactions include price alignment amounts either received or paid on the variation margin, which is characterized as interest and reflected in net investment income. Forward contracts are customized commitments that specify a rate of interest or currency exchange rate to be paid or received on an obligation beginning on a future start date and are typically settled in cash. Financial futures are standardized commitments to either purchase or sell designated financial instruments, at a future date, for a specified price and may be settled in cash or through delivery of the underlying instrument. Futures contracts trade on organized exchanges. Margin requirements for futures are met by pledging securities or cash, and changes in the futures’ contract values are settled daily in cash. Option contracts grant the purchaser, for a premium payment, the right to either purchase from or sell to the issuer a financial instrument at a specified price, within a specified period or on a stated date. The contracts may reference commodities, which grant the purchaser the right to either purchase from or sell to the issuer commodities at a specified price, within a specified period or on a stated date. Option contracts are typically settled in cash. Foreign currency swaps exchange an initial principal amount in two currencies, agreeing to re-exchange the currencies at a future date, at an agreed upon exchange rate. There may also be a periodic exchange of payments at specified intervals calculated using the agreed upon rates and exchanged principal amounts. The Company’s derivative transactions conducted in insurance company subsidiaries are used in strategies permitted under the derivative use plans required by the State of Connecticut, the State of Illinois and the State of New York insurance regulators. Accounting and Financial Statement Presentation of Derivative Instruments and Hedging Activities Derivative instruments are recognized on the Consolidated Balance Sheets at fair value and are reported in Other Investments and Other Liabilities. For balance sheet presentation purposes, the Company has elected to offset the fair value amounts, income accruals, and related cash collateral receivables and payables of OTC derivative instruments executed in a legal entity and with the same counterparty under a master netting agreement, which provides the Company with the legal right of offset. On the date the derivative contract is entered into, the Company designates the derivative as (1) a hedge of the fair value of a recognized asset or liability (“fair value” hedge), (2) a hedge of the variability in cash flows of a forecasted transaction or of amounts to be received or paid related to a recognized asset or liability (“cash flow” hedge), (3) a hedge of a net investment in a foreign operation (“net investment” hedge) or (4) held for other investment and/or risk management purposes, which primarily involve managing asset or liability related risks and do not qualify for hedge accounting. The Company currently does not designate any derivatives as fair value or net investment hedges. Cash Flow Hedges - Changes in the fair value of a derivative that is designated and qualifies as a cash flow hedge, including foreign-currency cash flow hedges, are recorded in AOCI and are reclassified into earnings when the variability of the cash flow of the hedged item impacts earnings. Gains and losses on derivative contracts that are reclassified from AOCI to current period earnings are included in the line item in the Consolidated Statements of Operations in which the cash flows of the hedged item are recorded. Periodic derivative net coupon settlements are recorded in the line item of the Consolidated Statements of Operations in which the cash flows of the hedged item are recorded. Cash flows from cash flow hedges are presented in the same category as the cash flows from the items being hedged in the Consolidated Statement of Cash Flows. Other Investment and/or Risk Management Activities - The Company’s other investment and/or risk management activities primarily relate to strategies used to reduce economic risk or replicate permitted investments and do not receive hedge accounting treatment. Changes in the fair value, including periodic derivative net coupon settlements, of derivative instruments held for other investment and/or risk management purposes are reported in current period earnings as net realized gains and losses. Hedge Documentation and Effectiveness Testing To qualify for hedge accounting treatment, a derivative must be highly effective in mitigating the designated changes in fair value or cash flows of the hedged item. At hedge inception, the Company formally documents all relationships between hedging instruments and hedged items, as well as its risk-management objective and strategy for undertaking each hedge transaction. The documentation process includes linking derivatives that are designated as fair value, cash flow, or net investment hedges to specific assets or liabilities on the balance sheet or to specific forecasted transactions and defining the effectiveness testing methods to be used. The Company also formally assesses both at the hedge’s inception and ongoing on a quarterly basis, whether the derivatives that are used in hedging transactions have been and are expected to continue to be highly effective in offsetting changes in fair values, cash flows or net investment in foreign operations of hedged items. Hedge effectiveness is assessed primarily using quantitative methods as well as using qualitative methods. Quantitative methods include regression or other statistical analysis of changes in fair value or cash flows associated with the hedge relationship. Qualitative methods may include comparison of critical terms of the derivative to the hedged item. Discontinuance of Hedge Accounting The Company discontinues hedge accounting prospectively when (1) it is determined that the qualifying criteria are no longer met; (2) the derivative is no longer designated as a hedging instrument; or (3) the derivative expires or is sold, terminated or exercised. When cash flow hedge accounting is discontinued because the Company becomes aware that it is not probable that the forecasted transaction will occur, the derivative continues to be carried on the balance sheet at its fair value, and gains and losses that were accumulated in AOCI are recognized immediately in earnings. In other situations in which hedge accounting is discontinued, including those where the derivative is sold, terminated or exercised, amounts previously deferred in AOCI are reclassified into earnings when earnings are impacted by the hedged item. Embedded Derivatives The Company may purchase investments that contain embedded derivative instruments. When it is determined that (1) the embedded derivative possesses economic characteristics that are not clearly and closely related to the economic characteristics of the host contract and (2) a separate instrument with the same terms would qualify as a derivative instrument, the embedded derivative is bifurcated from the host for measurement purposes. The embedded derivative, which is reported with the host instrument in the Consolidated Balance Sheets, is carried at fair value with changes in fair value reported in net realized gains and losses. Credit Risk of Derivative Instruments Credit risk is defined as the risk of financial loss due to uncertainty of an obligor’s or counterparty’s ability or willingness to meet its obligations in accordance with agreed upon terms. Credit exposures are measured using the market value of the derivatives, resulting in amounts owed to the Company by its counterparties or potential payment obligations from the Company to its counterparties. The Company generally requires that OTC derivative contracts, other than certain forward contracts, be governed by International Swaps and Derivatives Association agreements which are structured by legal entity and by counterparty, and permit right of offset. Some agreements require daily collateral settlement based upon agreed upon thresholds. For purposes of daily derivative collateral maintenance, credit exposures are generally quantified based on the prior business day’s market value and collateral is pledged to and held by, or on behalf of, the Company to the extent the current value of the derivatives is greater than zero, subject to minimum transfer thresholds, if applicable. The Company also minimizes the credit risk of derivative instruments by entering into transactions with high quality counterparties primarily rated A or better, which are monitored and evaluated by the Company’s risk management team and reviewed by senior management. OTC-cleared derivatives are governed by clearing house rules. Transactions cleared through a central clearing house reduce risk due to their ability to require daily variation margin and act as an independent valuation source. In addition, the Company monitors counterparty credit exposure on a monthly basis to ensure compliance with Company policies and statutory limitations. Cash and Restricted Cash Cash represents cash on hand and demand deposits with banks or other financial institutions. Restrictions on cash primarily relate to funds that are held to support regulatory and contractual obligations. Reinsurance The Company cedes insurance to other insurers in order to limit its maximum losses, to diversify its exposures and provide statutory surplus relief. Such arrangements do not relieve the Company of its primary liability to policyholders. Failure of reinsurers to honor their obligations could result in losses to the Company. The Company also assumes reinsurance from other insurers and is a member of and participates in reinsurance pools and associations. Assumed reinsurance refers to the Company’s acceptance of certain insurance risks that other insurance companies or pools have underwritten. Reinsurance accounting is followed for ceded and assumed transactions that provide indemnification against loss or liability relating to insurance risk (i.e., risk transfer). To meet risk transfer requirements, a reinsurance agreement must include insurance risk, consisting of underwriting and timing risk, and a reasonable possibility of a significant loss to the reinsurer. If the ceded and assumed transactions do not meet risk transfer requirements, the Company accounts for these transactions as deposit transactions. The Company had no deposit liability as of December 31, 2024 or and 2023 reported in other liabilities. Premiums, benefits, losses and loss adjustment expenses reflect the net effects of ceded and assumed reinsurance transactions. Included in other assets are prepaid reinsurance premiums, which represent the portion of premiums ceded to reinsurers applicable to the unexpired terms of the reinsurance contracts. Reinsurance recoverables are balances due from reinsurers for ceded paid and unpaid losses and loss adjustment expenses and are presented net of an allowance for uncollectible reinsurance. Changes in the allowance for uncollectible reinsurance are reported in benefits, losses and loss adjustment expenses in the Company's Consolidated Statements of Operations. The Company periodically evaluates the recoverability of its reinsurance recoverable assets and establishes an allowance for uncollectible reinsurance. The allowance for uncollectible reinsurance reflects management’s best estimate of reinsurance cessions that may be uncollectible in the future due to reinsurers’ unwillingness or inability to pay. The allowance for uncollectible reinsurance comprises an ACL and an allowance for disputed balances. Based on this analysis, the Company may adjust the allowance for uncollectible reinsurance or charge off reinsurer balances that are determined to be uncollectible. The Company records credit losses related to reinsurance recoverables in benefits, losses and loss adjustment expenses. Write-offs of reinsurance recoverables and any related ACL are recorded in the period in which the balance is deemed uncollectible. Expected recoveries are included in the estimate of the ACL. Retroactive reinsurance agreements, including adverse development covers ("ADC"), are reinsurance agreements under which our reinsurer agrees to reimburse us as a result of loss development related to past insurable events. For these agreements, the consideration paid in excess of the estimated ultimate losses to be recovered under the agreement at inception is recognized as a loss on reinsurance transaction. The benefit of subsequent adverse development ceded up to the total consideration paid is recognized as ceded losses, which are a reduction of incurred losses and loss adjustment expenses. The excess of the estimated amounts ultimately to be recovered under the agreement over the consideration paid is recognized as a deferred gain liability and amortized into income over the period the ceded losses are recovered in cash from the reinsurer. The amount of the deferred gain liability is recalculated each period based on cumulative recoveries not yet collected relative to the latest estimate of ultimate losses to be recovered. Ceded loss reserves under retroactive agreements were $1.6 billion and $1.7 billion, and the deferred gain liability reported in other liabilities was $914 and $997, as of December 31, 2024 and 2023, respectively. In any given period, the change in deferred gain included in net income includes amortization of the deferred gain based on the percentage of ultimate ceded losses collected plus any change in the deferred gain liability due to changes in the estimated ultimate losses to be recovered. The effect on income from change in the deferred gain was a net charge or (benefit) to earnings of $(83), $194 and $229 before tax for the years ended December 31, 2024, 2023, and 2022 respectively. Deferred Policy Acquisition Costs DAC represents costs that are directly related to the acquisition of new and renewal insurance contracts and incremental direct costs of contract acquisition that are incurred in transactions with independent third parties or in compensation to employees. Such costs primarily include commissions, premium taxes, costs and certain other expenses that are directly related to successfully issued contracts, including a portion of policy issuance and underwriting costs. For P&C insurance products and group life, disability and accident contracts, costs are deferred and amortized ratably over the period the related premiums are earned. Deferred acquisition costs are reviewed to determine if they are recoverable from future income, and if not, are charged to expense. Anticipated investment income is considered in the determination of the recoverability of DAC. Income Taxes The Company recognizes taxes payable or refundable for the current year and deferred taxes for the tax consequences of temporary differences between the financial reporting and tax basis of assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years the temporary differences are expected to reverse. A deferred tax provision is recorded for the tax effects of temporary differences between the Company's current taxable income and its income before tax under generally accepted accounting principles in the Consolidated Statements of Operations. For deferred tax assets, the Company records a valuation allowance that is adequate to reduce the total deferred tax asset to an amount that will more likely than not be realized. Goodwill Goodwill represents the excess of the cost to acquire a business over the acquisition date fair value of net assets acquired. Goodwill is not amortized but is reviewed for impairment at least annually or more frequently if events occur or circumstances change that would indicate that a triggering event for a potential impairment has occurred. Goodwill is tested for impairment by comparing the fair value of a reporting unit to its carrying value. Goodwill is impaired up to the amount that the carrying value of the reporting unit exceeds the fair value. A reporting unit is defined as an operating segment or one level below an operating segment. The Company’s reporting units, for which goodwill has been allocated consist of Business Insurance, Personal Insurance, Employee Benefits, and Hartford Funds. Management’s determination of the fair value of each reporting unit incorporates multiple inputs into discounted cash flow calculations, including assumptions that market participants would make in valuing the reporting unit. Assumptions include levels of economic capital required to support the business, future business growth, earnings projections, the weighted average cost of capital used for purposes of discounting and, for the Hartford Funds segment, assets under management. Decreases in business growth, decreases in earnings projections and increases in the weighted average cost of capital will all cause a reporting unit’s fair value to decrease, increasing the possibility of impairments. Intangible Assets Acquired intangible assets on the Consolidated Balance Sheets include purchased customer relationship and agency or other distribution rights and licenses measured at fair value at acquisition. The Company amortizes finite-lived other intangible assets over their useful lives generally on a straight-line basis over the period of expected benefit, ranging from 1 to 15 years. Management revises amortization periods if it believes there has been a change in the length of time that an intangible asset will continue to have value. Indefinite-lived intangible assets are not subject to amortization. Intangible assets are assessed for impairment generally when events or circumstances indicate a potential impairment and at least annually for indefinite-lived intangibles. Finite-lived intangible assets are impaired if the carrying amount is not recoverable from undiscounted cash flows. Indefinite-lived intangible assets are impaired if the carrying amount exceeds fair value. Impaired intangible assets are written down to fair value. Property and Equipment Property and equipment, which includes capitalized software and right-of-use lease assets, is carried at cost net of accumulated depreciation. Depreciation is based on the estimated useful lives of the various classes of property and equipment and is recognized principally on the straight-line method. Accumulated depreciation was $2.5 billion and $2.4 billion as of December 31, 2024 and 2023, respectively. Depreciation expense was $177, $204, and $213 for the years ended December 31, 2024, 2023 and 2022, respectively, and is reported in insurance operating costs and other expenses. The costs to access and develop hosted software arrangements, where The Hartford has the right to access and use the software, but not take possession, and the cost of certain software licenses are reported in other assets on a straight-line basis over the service period. Amortization of hosted software and certain software licenses was $108, $85, and $78 for the years ended December 31, 2024, 2023, and 2022, respectively, and is reported in insurance operating costs and other expenses. Leases Leases are classified as financing or operating leases. Where the lease is economically similar to a purchase because The Hartford obtains control of the underlying asset, the lease is classified as a financing lease and the Company recognizes amortization of the right of use asset and interest expense on the liability. Where the lease is not economically similar to a purchase as the lease provides The Hartford with only the right to control the use of the underlying asset over the lease term and the lease term is greater than one year, the lease is an operating lease and the lease cost is recognized as rental expense over the lease term on a straight-line basis. Leases with a term of one year or less are also expensed over the lease term but not recognized on the Consolidated Balance Sheets. Unpaid Losses and Loss Adjustment Expenses For property and casualty and group life, disability and accident insurance and assumed reinsurance products, the Company establishes reserves for unpaid losses and loss adjustment expenses to provide for the estimated costs of paying claims under insurance policies written by the Company. These reserves include estimates for both claims that have been reported and those that have not yet been reported, and include estimates of all losses and loss adjustment expenses associated with processing and settling these claims. Estimating the ultimate cost of future losses and loss adjustment expenses is an uncertain and complex process. This estimation process is based significantly on the assumption that past developments are an appropriate predictor of future events, and involves a variety of actuarial techniques that analyze experience, trends and other relevant factors. The effects of inflation are implicitly considered in the reserving process. In addition, a number of complex factors influence the uncertainties involved with the reserving process including social and economic trends and changes in the concepts of legal liability and damage awards. Accordingly, final claim settlements may vary from the present estimates, particularly when those payments may not occur until well into the future. The Company regularly reviews the adequacy of its estimated losses and loss adjustment expense reserves by reserve line within the various reportable segments. Adjustments to previously established reserves are reflected in the operating results of the period in which the adjustment is determined to be necessary. Such adjustments could possibly be significant, reflecting any variety of new and adverse or favorable trends. Most of the Company’s property and casualty insurance products reserves are not discounted. However, the Company has discounted to present value certain reserves for indemnity payments that are due to claimants under workers’ compensation policies because the payment pattern and the ultimate costs are reasonably fixed and determinable on an individual claim basis. The discount rate is based on the risk free rate for the expected claim duration as determined in the year the claims were incurred. The Company also has discounted liabilities for structured settlement agreements that provide fixed periodic payments to claimants. These structured settlements include annuities purchased to fund unpaid losses for permanently disabled claimants. These structured settlement liabilities are discounted to present value using the rate implicit in the purchased annuities and the purchased annuities are accounted for within reinsurance recoverables. Group life and disability contracts with long-tail claim liabilities are discounted because the payment pattern and the ultimate costs are reasonably fixed and determinable on an individual claim basis. The discount rates are estimated based on investment yields expected to be earned on the cash flows net of investment expenses and expected credit losses. The Company establishes discount rates for these reserves in the year the claims are incurred (the incurral year) which is when the estimated settlement pattern is determined. The discount rate for life and disability reserves acquired from Aetna's U.S. group life and disability business were based on interest rates in effect at the acquisition date of November 1, 2017. For further information about how unpaid losses and loss adjustment expenses are established, see Note 10 - Reserve for Unpaid Losses and Loss Adjustment Expenses. Reserve for Future Policy Benefits The Company’s reserves for future policy benefits includes paid-up life insurance and whole-life policies resulting from conversion from group life policies included within the Employee Benefits segment and reserves for run-off structured settlement and terminal funding agreement liabilities, which are reported in the Corporate category. Contracts are grouped into cohorts by contract type and issue year. The Company establishes reserves for future policy benefits using the net premium approach, which represents the present value of future policyholder benefits and related expenses less the present value of future net premiums. Net premiums are calculated by multiplying gross premiums for the contracts in a specific cohort by a net premium ratio. The net premium ratio is determined for the lifetime of a given cohort as the present value of net benefits divided by the present value of gross premiums. Related expenses include termination and settlement costs and exclude acquisition costs and non-claim related costs, such as costs relating to investments, general administration, policy maintenance, product development, market research and general overhead or any other costs, which are expensed as incurred. The Company estimates premiums, benefits and related expense cash flows using methods that include assumptions, such as estimates of mortality, lapse, and claim-related expenses, and the possible impact of inflation on those expenses. Benefits include all guaranteed cash flows to be paid to the policyholder. The reserve for future policy benefits is adjusted for differences between actual and expected experience. Each quarter, the Company updates its estimates of cash flows expected over the life of a group of contracts using actual historical experience. These updated cash flows are used to calculate the revised net premiums and net premium ratio, which are used to derive an updated reserve for future policy benefits. In subsequent periods, the revised net premiums are used to measure the reserve for future policy benefits, subject to future revisions. Future cash flow assumptions, including mortality, lapse and expense are reviewed and, if a change is indicated, updated at least annually in the third quarter. The difference between the newly calculated reserve balance and the reserve balance before updating for actual experience and/or future cash flow assumptions is the remeasurement gain or loss, which is immaterial for each of the years ended December 31, 2024, 2023 and 2022, and is presented in benefits losses and loss adjustments expense in the Consolidated Statements of Operations. Changes to the reserve due to updates to cash flow assumptions, discounted at the discount rate used when each annual cohort was established, are recognized on a catch-up basis in the Consolidated Statement of Operations. The discount rate assumption is an equivalent single rate that is based on a current market observable, upper-medium grade fixed maturity yield. This has been interpreted to represent a yield based on single-A credit rated fixed maturity instruments with similar duration to the liability. The Company uses the yield of a market observable index of single-A credit rated fixed maturities as the basis for setting the discount rate. The discount rate assumption is updated quarterly and the change in the reserve estimate resulting from updating the discount rate assumption is recognized in other comprehensive income. Treasury Stock Treasury stock is the cost of common stock repurchased, which includes the purchase price of shares acquired and direct costs to acquire shares, including commissions and excise taxes. Issuance and retirement of treasury stock is recognized at the average cost of shares held in treasury. Foreign Currency Foreign currency translation gains and losses are reflected in stockholders’ equity as a component of AOCI. The Company’s foreign subsidiaries’ balance sheet accounts are translated at the exchange rates in effect at each year end and income statement accounts are translated at the average rates of exchange prevailing during the year. The national currencies of the international operations are generally their functional currencies; however, the U.S. dollar is the functional currency of Lloyd's Syndicate 1221 ("Lloyd's Syndicate"), for which the Company is the sole corporate member. Gains and losses resulting from the remeasurement of foreign currency transactions are reflected in earnings in net realized gains (losses) in the period in which they occur.
Commitments and Contingencies Disclosure [Text Block]	14. COMMITMENTS AND CONTINGENCIES Management evaluates each contingent matter separately. A loss is recorded if probable and reasonably estimable. Management establishes liabilities for these contingencies at its “best estimate,” or, if no one number within the range of possible losses is more probable than any other, the Company records an estimated liability at the low end of the range of losses. The Hartford is involved in claims litigation arising in the ordinary course of business, both as a liability insurer defending or providing indemnity for third-party claims brought against insureds and as an insurer defending coverage claims brought against it. The Hartford accounts for such activity through the establishment of unpaid loss and loss adjustment expense reserves. Subject to the uncertainties related to sexual molestation and sexual abuse claims, including those discussed in Note 10, Reserve for Unpaid Losses and Loss Adjustment Expenses, and in the following discussion under the caption “Run-off Asbestos and Environmental Claims,” management expects that the ultimate liability, if any, with respect to such ordinary-course claims litigation, after consideration of provisions made for potential losses and costs of defense, will not be material to the consolidated financial condition, results of operations or cash flows of The Hartford. The Hartford is also involved in other kinds of legal actions, some of which assert claims for substantial amounts. In addition to the matter described below, these actions include putative class actions seeking certification of a state or national class. Such putative class actions have alleged, for example, underpayment of claims or improper sales or underwriting practices in connection with various kinds of insurance policies, such as personal and commercial automobile and property. The Hartford also is involved in individual actions in which punitive damages are sought, such as claims alleging bad faith in the handling of insurance claims or other allegedly unfair or improper business practices. Management expects that the ultimate liability, if any, with respect to such lawsuits, after consideration of provisions made for estimated losses, will not be material to the consolidated financial condition of The Hartford. Nonetheless, given the large or indeterminate amounts sought in certain of these actions, and the inherent unpredictability of litigation, the outcome in certain matters could, from time to time, have a material adverse effect on the Company’s results of operations or cash flows in particular quarterly or annual periods. Run-off Asbestos and Environmental Claims The Company continues to receive A&E claims. Asbestos claims relate primarily to bodily injuries asserted by people who came in contact with asbestos or products containing asbestos. Environmental claims relate primarily to pollution and related clean-up costs. The vast majority of the Company's exposure to A&E relates to accident years prior to 1986 that are reported in Property & Casualty Other Operations ("Run-off A&E"). In addition, since 1986, the Company has written asbestos and environmental exposures under general liability policies and pollution liability under homeowners policies, which are reported in the Business Insurance and Personal Insurance segments, respectively. Prior to 1986, the Company wrote several different categories of insurance contracts that may cover A&E claims. First, the Company wrote primary policies providing the first layer of coverage in an insured’s liability program. Second, the Company wrote excess and umbrella policies providing higher layers of coverage for losses that exhaust the limits of underlying coverage. Third, the Company acted as a reinsurer assuming a portion of those risks assumed by other insurers writing primary, excess, umbrella and reinsurance coverages. Significant uncertainty limits the ability of insurers and reinsurers to estimate the ultimate reserves necessary for unpaid gross losses and expenses related to environmental and asbestos claims. The degree of variability of gross reserve estimates for these exposures is significantly greater than for other more traditional exposures. In the case of the reserves for asbestos exposures, factors contributing to the high degree of uncertainty include inadequate loss development patterns, plaintiffs’ expanding theories of liability, the risks inherent in major litigation, and inconsistent and emerging legal doctrines with respect to the underlying claims and with respect to the Company's coverage obligations. Furthermore, over time, insurers, including the Company, have experienced significant changes in the rate at which asbestos claims are brought, the claims experience of particular insureds, and the value of claims, making predictions of future exposure from past experience uncertain. Plaintiffs and insureds also have sought to use bankruptcy proceedings, including “pre-packaged” bankruptcies, to accelerate and increase loss payments by insurers. In addition, some policyholders have asserted new classes of claims for coverages to which an aggregate limit of liability may not apply. Further uncertainties include insolvencies of other carriers, insolvencies of insureds and unanticipated developments pertaining to the Company’s ability to recover reinsurance for A&E claims. Management believes these issues are not likely to be resolved in the near future. In the case of the reserves for environmental exposures, factors contributing to the high degree of uncertainty include expanding theories of liability and damages against insureds, emerging risks from products and substances alleged to cause damage, such as per-and polyfluoroalkyl substances ("PFAS"), the risks inherent in major litigation, inconsistent and emerging legal doctrines concerning the existence and scope of coverage for environmental claims, and the scope and level of complexity of the remediation required by regulators. The reporting pattern for assumed reinsurance claims, including those related to A&E claims, is much longer than for direct claims. In many instances, it takes months or years to determine that the policyholder’s own obligations have been met and how the reinsurance in question may apply to such claims. The delay in reporting reinsurance claims and exposures adds to the uncertainty of estimating the related reserves. It is also not possible to predict changes in the legal and legislative environment and their effect on the future development of A&E claims. Given the factors described above, the Company believes the actuarial tools and other techniques it employs to estimate the ultimate cost of claims for more traditional kinds of insurance exposure are less precise in estimating reserves for A&E exposures. For this reason, the Company principally relies on exposure-based analysis to estimate the ultimate costs of these claims, both gross and net of reinsurance, and regularly evaluates new account information in assessing its potential A&E exposures. The Company supplements this exposure-based analysis with evaluations of the Company’s historical direct net loss and expense paid and reported experience, and net loss and expense paid and reported experience by calendar and/or report year, to assess any emerging trends, fluctuations or characteristics suggested by the aggregate paid and reported activity. For its Run-off A&E claims, as of December 31, 2024, the Company reported $224 of net asbestos and environmental reserves, including the benefit of losses ceded to the A&E ADC with NICO. In addition, the Company has recorded $850, including $62 in 2024, of a deferred gain within other liabilities for losses economically ceded to NICO but for which the benefit is not recognized in earnings until later periods. While the Company believes that its current Run-off A&E reserves are appropriate, significant uncertainties limit our ability to estimate the ultimate reserves necessary for unpaid losses and related expenses. The ultimate liabilities, thus, could exceed the currently recorded reserves, and any such additional liability, while not reasonably estimable now, could be material to The Hartford's consolidated operating results or liquidity. The Company’s A&E ADC reinsurance agreement reinsures substantially all A&E reserve development for 2016 and prior accident years, including Run-off A&E and A&E reserves included in Business Insurance and Personal Insurance. The A&E ADC has a coverage limit of $1.5 billion above the Company’s existing net A&E reserves as of December 31, 2016 of approximately $1.7 billion. As of December 31, 2024, the Company has incurred $1.5 billion in cumulative adverse development on A&E reserves that have been ceded under the A&E ADC treaty, leaving no remaining coverage available for future adverse net reserve development, if any. Cumulative adverse development of A&E claims for accident years 2016 and prior in excess of the treaty limit, including $141 recognized in 2024, are absorbed as a charge to earnings by the Company. The effect of future charges could be material to the Company’s consolidated operating results or liquidity. For more information on the A&E ADC, refer to Note 10, Reserve for Unpaid Losses and Loss Adjustment Expenses Unfunded Commitments As of December 31, 2024, the Company has outstanding commitments totaling $3.8 billion, of which $2.1 billion is committed to fund limited partnerships and other alternative investments, which may be called by the partnership during the commitment period to fund the purchase of new investments and partnership expenses. The funding of purchase investments in limited partnerships and other alternative investments are at the discretion of the general partner or manager and may be called at any time. Additionally, $1.0 billion of the outstanding commitments relate to various funding obligations associated with private debt and equity securities, as well as tax credits. The remaining outstanding commitments of $636 relate to mortgage loans. Of the $3.8 billion in total outstanding commitments, $53 are related to mortgage loan commitments which the Company can cancel unconditionally. Guaranty Funds and Other Insurance-related Assessments In all states, insurers licensed to transact certain classes of insurance are required to become members of a guaranty fund. In most states, in the event of the insolvency of an insurer writing any such class of insurance in the state, a guaranty fund may assess its members to pay covered claims of the insolvent insurers. Assessments are based on each member's proportionate share of written premiums in the state for the classes of insurance in which the insolvent insurer was engaged. Assessments are generally limited for any year to one or two percent of the premiums written per year depending on the state. Some states permit member insurers to recover assessments paid through surcharges on policyholders or through full or partial premium tax offsets, while other states permit recovery of assessments through the rate filing process. Liabilities for guaranty fund and other insurance-related assessments are accrued when an assessment is probable, when it can be reasonably estimated, and when the event obligating the Company to pay an imposed or probable assessment has occurred. Liabilities for guaranty funds and other insurance-related assessments are not discounted and are included as part of other liabilities in the Consolidated Balance Sheets. As of December 31, 2024 and 2023 the liability balance was $70 and $77, respectively. As of December 31, 2024 and 2023, there were $0 of premium tax offsets related to guaranty fund or other insurance-related assessments for both periods. Derivative Commitments Certain of the Company’s derivative agreements contain provisions that are tied to the financial strength ratings, as set by nationally recognized statistical agencies, of the individual legal entity that entered into the derivative agreement. If the legal entity’s financial strength were to fall below certain ratings, the counterparties to the derivative agreements could, in certain instances, terminate the agreements and demand immediate settlement of all outstanding derivative positions traded under each impacted bilateral agreement. The settlement amount is determined by netting the derivative positions transacted under each agreement. If the termination rights were to be exercised by the counterparties, it could impact the legal entity’s ability to conduct hedging activities by increasing the associated costs and decreasing the willingness of counterparties to transact with the legal entity. The aggregate fair value of all derivative instruments with credit-risk-related contingent features that are in a net liability position as of December 31, 2024 was $33 for which the legal entities have posted collateral of $31 in the normal course of business. Based on derivative contractual terms as of December 31, 2024, a downgrade of the current financial strength ratings by either Moody's or S&P would not require additional assets to be posted as collateral. This requirement could change as a result of changes in our hedging activities or to the extent changes in contractual terms are negotiated. The nature of the additional collateral that we would post, if required, would be primarily in the form of U.S. Treasury bills, U.S. Treasury notes and government agency securities. Guarantees In the ordinary course of selling businesses or entities to third parties, the Company has agreed to indemnify purchasers for losses arising subsequent to the closing due to breaches of representations and warranties with respect to the business or entity being sold or with respect to covenants and obligations of the Company and/or its subsidiaries. These obligations are typically subject to various time limitations, defined by the contract or by operation of law, such as statutes of limitation. In some cases, the maximum potential obligation is subject to contractual limitations, while in other cases such limitations are not specified or applicable. The Company does not expect to make any material payments on these guarantees and is not carrying any material liabilities associated with these guarantees. The Hartford has guaranteed the timely payment of contractual claims under certain life, accident and health and annuity contracts issued by its former life and annuity business with most of the guaranteed contracts issued between 1990 and 1997 (the "Talcott Guarantees"). Upon the sale of the life and annuity business in May 2018, the purchaser indemnified the Company for any liability arising under the guarantees. The Talcott Guarantees cover contractual obligations only but otherwise have no limitation as to maximum potential future payments. The liability for credit losses ("LCL") for Talcott Guarantees is calculated for the estimated amount payable under guaranteed contracts multiplied by the probability of default and the amount of loss given a default. The probability of default is assigned by credit rating of the applicable insurance company that issued the contract and is based on historical insurance industry defaults for liabilities with similar durations estimated through multiple economic cycles. Credit ratings are current and forward-looking and consider a variety of economic outcomes. Because annuities represent the majority of the contracts issued, the loss given default factors are based on a historical study of annuity policyholder recoveries from insolvent estate assets. The Company's exposure is expected to run off over a period that will include more than one economic cycle. The Company's evaluation of the required LCL for the Talcott Guarantees considers the current economic environment as well as macroeconomic scenarios similar to the approach used to estimate the ACL for mortgage loans. See Note 5 - Investments. In 2022, the LCL decreased from $25 to $22 primarily reflecting a decrease in the estimated amount payable under guaranteed contracts. In 2023, the LCL decreased to $9 primarily due to an upgrade of Talcott's credit rating, as well as a decrease in the estimated amount payable under guaranteed contracts. During 2024, the LCL decreased to $7 primarily due to an improvement of Talcott's assumed liquidation rate, as well as a decrease in the estimated amount payable under guaranteed contracts. The Company has never experienced a loss on financial guarantees similar to the Talcott Guarantees and we believe the risk of loss is remote.
