Accounting Policies [Abstract]  
Basis of Presentation and Accounting Policies
1. Basis of Presentation and Significant Accounting Policies
Basis of Presentation
The Hartford Insurance Group, Inc. is a holding company for subsidiaries that primarily provide property and casualty insurance, and employee group benefits insurance and services, 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”).
On June 3, 2026, the Company entered into a definitive agreement to sell Hartford Funds Management Group, Inc. ("Hartford Funds"), a subsidiary of Hartford Holdings, Inc. For further discussion of this transaction, see Note 17 - Discontinued Operations of Notes to Condensed Consolidated Financial Statements.
The Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information, which differ materially from the accounting practices prescribed by various insurance regulatory authorities. These Condensed Consolidated Financial Statements and Notes should be read in conjunction with the Consolidated Financial Statements and Notes thereto included in the Company's 2025 Form 10-K Annual Report. The results of operations for interim periods are not necessarily indicative of the results that may be expected for the full year.
The accompanying Condensed Consolidated Financial Statements and Notes are unaudited. These financial statements reflect all adjustments (generally consisting only of normal accruals) which are, in the opinion of management, necessary for the fair statement of the financial position, results of operations and cash flows for the interim periods.
Consolidation
The Condensed 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.
Discontinued Operations
The results of operations of a component of the Company are reported in discontinued operations when certain criteria are met as of the date of disposal, or earlier if classified as held-for-sale. When a component is identified for discontinued operations reporting, amounts for prior periods are retrospectively reclassified as discontinued operations. Components are identified as discontinued operations if they are a major part of an entity's operations and financial results such as a separate major line of business or a separate major geographical area of operations. Hartford Funds has met the criteria for reporting as discontinued operations and is reported in the Corporate category until closing.
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.
Reclassifications
Certain reclassifications have been made to prior period financial information to conform to the current period presentation. In particular, prior period results of operations associated with the Company's Hartford Funds business have been retrospectively reclassified to discontinued operations and assets and liabilities associated with the Hartford Funds business are classified as assets and liabilities held for sale within the Corporate category.

Fair Value Disclosures [Abstract]  
Fair Value Measurements
4. Fair Value Measurements
The Company carries certain financial assets and liabilities at estimated fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants. Our fair value framework includes a hierarchy that gives the highest priority to the use of quoted prices in active markets, followed by the use of market observable inputs, followed by the use of unobservable inputs.
The fair value hierarchy levels are as follows:
Level 1    Fair values based on unadjusted quoted prices for identical assets or liabilities, in active markets that the Company has the ability to access at the measurement date.
Level 2    Fair values primarily based on observable inputs, other than quoted prices included in Level 1, or based on prices for similar assets and liabilities.
Level 3    Fair values derived when one or more of the significant inputs are unobservable (including assumptions about risk). With little or no observable market, the determination of fair values uses considerable judgment and represents the Company’s best estimate of an amount that could be realized in a market exchange for the asset or liability. Also included are securities that are traded within illiquid markets and/or priced by independent brokers.
The Company will classify the financial asset or liability by level based upon the lowest level input that is significant to the determination of the fair value. In most cases, both observable inputs (e.g., changes in interest rates) and unobservable inputs (e.g., changes in risk assumptions) are used to determine fair values that the Company has classified within Level 3.

Fixed Maturities, Equity Securities, Short-term Investments, and Derivatives
Valuation Techniques
The Company generally determines fair values using valuation techniques that use prices, rates, and other relevant information evident from market transactions involving identical or similar
instruments. Valuation techniques also include, where appropriate, estimates of future cash flows that are converted into a single discounted amount using current market expectations. The Company uses a "waterfall" approach comprised of the following pricing sources and techniques, which are listed in priority order:
•Quoted prices, unadjusted, for identical assets or liabilities in active markets, which are classified as Level 1.
•Prices from third-party pricing services, which primarily utilize a combination of techniques. These services utilize recently reported trades of identical, similar, or benchmark securities making adjustments for market observable inputs available through the reporting date. If there are no recently reported trades, they may use a discounted cash flow technique to develop a price using expected cash flows
based upon the anticipated future performance of the underlying collateral discounted at an estimated market rate. Both techniques develop prices that consider the time value of future cash flows and provide a margin for risk, including liquidity and credit risk. Most prices provided by third-party pricing services are classified as Level 2 because the inputs used in pricing the securities are observable. However, some securities that are less liquid or trade less actively are classified as Level 3. Additionally, certain long-dated securities include benchmark interest rate or credit spread assumptions that are not observable in the marketplace and are thus classified as Level 3.
•Internal matrix pricing is a valuation process internally developed for private placement securities for which the Company is unable to obtain a price from a third-party pricing service. Internal pricing matrices determine credit spreads that, when combined with risk-free rates, are applied to contractual cash flows to develop a price. The Company develops credit spreads using market based data for public securities adjusted for credit spread differentials between public and private securities, which are obtained from a survey of multiple private placement brokers. The market-based reference credit spread considers the issuer’s sector, financial strength, and term to maturity, using an independent public security index, while the credit spread differential considers the non-public nature of the security. Securities priced using internal matrix pricing are classified as Level 2 because the significant inputs are observable or can be corroborated with observable data.
•Independent broker quotes, which are typically non-binding, use inputs that can be difficult to corroborate with observable market-based data. Brokers may use present value techniques using assumptions specific to the security types, or they may use recent transactions of similar securities. Due to the lack of transparency in the process that brokers use to develop prices, valuations that are based on independent broker quotes are classified as Level 3. As of June 30, 2026 and December 31, 2025, no significant adjustments were made by the Company to broker prices received.
•Internal valuation models are used when third-party pricing or independent broker quotes are not available. These internally developed models incorporate market-based credit spreads from independent public security indexes reflective of comparable quality, maturity, and sector, adjusted for the non-public nature of the security. These securities are classified as Level 3 since they are not observable in the marketplace.
The fair value of derivative instruments is determined primarily using a discounted cash flow model or option model technique and incorporates counterparty credit risk. In some cases, quoted market prices for exchange-traded and over-the-counter ("OTC") cleared derivatives may be used and in other cases independent broker quotes may be used. The pricing valuation models primarily use inputs that are observable in the market or can be corroborated by observable market data. The valuation of certain derivatives may include significant inputs that are unobservable, such as volatility levels, and reflect the Company’s view of what other market participants would use when pricing such instruments.
Valuation Controls
The process for determining the fair value of investments is monitored by the Valuation Committee, which is a cross-functional group of senior management within the Company. The purpose of the Valuation Committee is to provide oversight of the pricing policy, procedures, and controls, including approval of valuation methodologies and pricing sources. The Valuation Committee reviews market data trends, pricing statistics and trading statistics to ensure that prices are reasonable and consistent with our fair value framework. Controls and procedures used to assess third-party pricing services are reviewed by the Valuation Committee, including the results of annual due-diligence reviews. Controls include, but are not limited to, reviewing daily and monthly price changes, stale prices, and missing prices and comparing new trade prices to third-party pricing services, weekly price changes to published bond index prices, and daily OTC derivative market valuations to counterparty valuations. The Company has a dedicated pricing group that works with trading and investment professionals to challenge prices received by a third-party pricing source if the Company believes that the valuation received does not accurately reflect the fair value. New valuation models and changes to current models require approval by the Valuation Committee. In addition, the Company’s enterprise-wide Operational Risk Management function provides an independent review of the suitability and reliability of model inputs, as well as an analysis of significant changes to current models.
Valuation Inputs
Quoted prices for identical assets in active markets are considered Level 1 and consist of on-the-run U.S. Treasuries, money market funds, exchange-traded equity securities, open-ended mutual funds, certain short-term investments, and exchange traded derivative instruments.

Non-cash investing activities for both the three and six months ended June 30, 2026, included $264 related to a reclass from short term to fixed maturities driven by an extension. There were no non-cash investing activities for both the three and six months ended June 30, 2025.
Accrued Investment Income on Fixed Maturities, AFS and Mortgage Loans
As of June 30, 2026 and December 31, 2025, the Company reported accrued investment income related to fixed maturities, AFS of $448 and $439, respectively, and accrued investment income related to mortgage loans of $27 and $25, respectively. These amounts are not included in the carrying value of the fixed maturities or mortgage loans. Investment income on fixed maturities and mortgage loans is accrued unless it is past due over 90 days or management deems the interest uncollectible. The Company does not include the current accrued investment income balance when estimating the ACL. The Company has a policy to write-off accrued investment income balances that are more than 90 days past due. Write-offs of accrued investment income are recorded as a credit loss component of net realized gains and losses.
Recognition and Presentation of Intent-to-Sell Impairments and ACL on Fixed Maturities, AFS
The Company will record an "intent-to-sell impairment" as a reduction to the amortized cost of fixed maturities, AFS in an unrealized loss position if the Company intends to sell or it is
more likely than not that the Company will be required to sell the fixed maturity before a recovery in value. A corresponding charge is recorded in net realized losses equal to the difference between the fair value on the impairment date and the amortized cost basis of the fixed maturity before recognizing the impairment.
For fixed maturities where a credit loss has been identified and no intent-to-sell impairment has been recorded, the Company will record an ACL for the portion of the unrealized loss related to the credit loss. Any remaining unrealized loss on a fixed maturity after recording an ACL is the non-credit amount and is recorded in OCI. The ACL is the excess of the amortized cost over the greater of the Company's best estimate of the present value of expected future cash flows or the security's fair value. Cash flows are discounted at the effective yield that is used to record interest income. The ACL cannot exceed the unrealized loss and, therefore, it may fluctuate with changes in the fair value of the fixed maturity if the fair value is greater than the Company's best estimate of the present value of expected future cash flows. The initial ACL and any subsequent changes are recorded in net realized gains and losses. The ACL is written off against the amortized cost in the period in which all or a portion of the related fixed maturity is determined to be uncollectible.
Developing the Company’s best estimate of expected future cash flows is a quantitative and qualitative process that incorporates information received from third-party sources along with certain internal assumptions regarding the future performance. The Company's considerations include, but are not limited to, (a) changes in the financial condition of the issuer and/or the underlying collateral, (b) whether the issuer is current on contractually obligated interest and principal payments, (c) credit ratings, (d) payment structure of the security and (e) the
extent to which the fair value has been less than the amortized cost of the security.
For non-structured securities, assumptions include, but are not limited to, economic and industry-specific trends and fundamentals, instrument-specific developments including changes in credit ratings, industry earnings multiples and the issuer’s ability to restructure, access capital markets, and execute asset sales.
For structured securities, assumptions include, but are not limited to, various performance indicators such as historical and
projected default and recovery rates, credit ratings, current and projected delinquency rates, loan-to-value ("LTV") ratios, average cumulative collateral loss rates that vary by vintage year, prepayment speeds, and property value declines. These assumptions require the use of significant management judgment and include the probability of issuer default and estimates regarding timing and amount of expected recoveries, which may include estimating the underlying collateral value.

As of June 30, 2026, fixed maturities, AFS in an unrealized loss position consisted of 3,266 instruments and were primarily depressed due to higher interest rates and/or wider credit spreads since the purchase date. As of June 30, 2026, 95% of these fixed maturities were depressed less than 20% of cost or amortized cost. The increase in unrealized losses during the six months ended June 30, 2026, was primarily attributable to higher interest rates.
Most of the fixed maturities depressed for twelve months or more relate to the corporate sector, RMBS, and municipal bonds, which were primarily depressed because current rates are higher and/or market spreads are wider than at the respective purchase dates. The Company neither has an intention to sell nor does it expect to be required to sell the fixed maturities outlined in the preceding discussion. The decision to record credit losses on fixed maturities, AFS in the form of an ACL requires us to make qualitative and quantitative estimates of expected future cash flows.
Mortgage Loans
ACL on Mortgage Loans
The Company reviews mortgage loans on a quarterly basis to estimate the ACL with changes in the ACL recorded in net realized gains and losses. Apart from an ACL recorded on individual mortgage loans where the borrower is experiencing financial difficulties, the Company records an ACL on the pool of mortgage loans based on lifetime expected credit losses. The Company utilizes a third-party forecasting model to estimate lifetime expected credit losses at a loan level under multiple economic scenarios. The scenarios use macroeconomic data provided by an internationally recognized economics firm that generates forecasts of varying economic factors such as GDP growth, unemployment and interest rates. The economic scenarios are projected over 10 years. The first two to four years of the 10-year period assume a specific modeled economic scenario (including moderate upside, moderate recession and severe recession scenarios) and then revert to historical long-term assumptions over the remaining period. Using these economic scenarios, the forecasting model projects property-specific operating income and capitalization rates used to estimate the value of a future operating income stream. The operating income and the property valuations derived from capitalization rates are compared to loan payment and principal amounts to create debt service coverage ratios ("DSCRs") and LTVs over the forecast period. The Company's process also considers qualitative factors. The model overlays historical data about mortgage loan performance based on DSCRs and LTVs and projects the probability of default, amount of loss given a default and resulting expected loss through maturity for each loan under each economic scenario. Economic scenarios are probability-weighted based on a statistical analysis of the forecasted economic factors and qualitative analysis. The Company records the change in the ACL on mortgage loans based on the weighted-average expected credit losses across the selected economic scenarios.
When a borrower is experiencing financial difficulty, including when foreclosure is probable, the Company measures an ACL on individual mortgage loans. The ACL is established for any shortfall between the amortized cost of the loan and the fair value of the collateral less costs to sell. Estimates of collectibility
from an individual borrower require the use of significant management judgment and include the probability and timing of borrower default and loss severity estimates. In addition, cash flow projections may change based upon new information about the borrower's ability to pay and/or the value of underlying collateral such as changes in projected property value estimates. During the period in which all or a portion of the mortgage loan is determined to be uncollectible, the ACL is written off against the amortized cost.
There were no mortgage loans held-for-sale as of June 30, 2026 or December 31, 2025. For the three and six months ended June 30, 2026 and 2025, the Company had no mortgage loans that have had extensions or restructurings other than what is allowable under the original terms of the contract or with borrowers experiencing financial difficulties.

The weighted-average LTV ratio of the Company’s mortgage loan portfolio was 56% as of June 30, 2026, while the weighted-average LTV ratio at origination of these loans was 58%. LTV ratios compare the loan amount to the value of the underlying property collateralizing the loan with property values based on appraisals updated no less than annually. Factors considered in estimating property values include, among other things, actual and expected property cash flows, geographic market data and the ratio of the property's net operating income to its value. DSCR compares a property’s net operating income to the borrower’s principal and interest payments and are updated no less than annually through reviews of underlying properties.

Past-Due Mortgage Loans
Mortgage loans are considered past due if a payment of principal or interest is not received according to the contractual terms of the loan agreement, which typically includes a grace period. As of June 30, 2026, the Company held one commercial mortgage loan that was 60 days past due, with an amortized cost of $8 and an ACL of $4. The loan is on non-accrual status and is not accruing interest income. As of December 31, 2025, the Company held no mortgage loans considered past due.
Mortgage Servicing
The Company originates, sells and services commercial mortgage loans on behalf of third parties and recognizes servicing fee income over the period that services are
performed. As of June 30, 2026, under this program, the Company serviced mortgage loans with a total outstanding principal of $10.7 billion, of which $4.8 billion was serviced on behalf of third parties and $5.9 billion was retained and reported in total investments on the Company's Condensed Consolidated Balance Sheets. As of December 31, 2025, the Company serviced mortgage loans with a total outstanding principal balance of $10.4 billion, of which $4.8 billion was serviced on behalf of third parties and $5.6 billion was retained and reported in total investments on the Company's Condensed Consolidated Balance Sheets. Servicing rights are carried at the lower of cost or fair value and were $0 as of June 30, 2026 and December 31, 2025, because servicing fees were market-level fees at origination and remain adequate to compensate the Company for servicing the loans.
Variable Interest Entities
The Company is engaged with various special purpose entities and other entities that are deemed to be variable interest entities ("VIEs") primarily as an investor through normal investment activities or, at times, as an investment manager.
A VIE is an entity that either has investors that lack certain essential characteristics of a controlling financial interest, such as simple majority kick-out rights, or lacks sufficient funds to finance its own activities without financial support provided by other entities. The Company performs ongoing qualitative assessments of its VIEs to determine whether the Company has a controlling financial interest in the VIE and therefore is the primary beneficiary. The Company is deemed to have a controlling financial interest when it has both the ability to direct the activities that most significantly impact the economic performance of the VIE and the obligation to absorb losses or right to receive benefits from the VIE that could potentially be significant to the VIE. Based on the Company’s assessment, if it determines it is the primary beneficiary, the Company consolidates the VIE in the Company’s Condensed Consolidated Financial Statements.
Consolidated VIEs
As of June 30, 2026 and December 31, 2025, the Company did not hold any securities for which it is the primary beneficiary.
Non-Consolidated VIEs
The Company, through normal investment activities, makes passive investments in limited partnerships and other alternative investments. For these non-consolidated VIEs, the Company has determined it is not the primary beneficiary as it has no ability to direct activities that could significantly affect the economic performance of the investments. The Company’s maximum exposure to loss as of June 30, 2026 and December 31, 2025 was limited to the total carrying value of $4.3 billion and $4.0 billion, respectively, which are a portion of the investments in limited partnerships and other alternative investments in the Company's Condensed Consolidated Balance Sheets that are primarily recorded using the equity method of accounting. As of June 30, 2026 and December 31, 2025, the Company has outstanding commitments totaling $2.8 billion and $2.4 billion, respectively, whereby the Company is committed to fund these investments and may be called by the partnership during the commitment period to fund the purchase of new investments and partnership expenses. These
investments are generally of a passive nature in that the Company does not take an active role in management. For further discussion of these investments, see Equity Method Investments within Note 5 - Investments of Notes to Consolidated Financial Statements included in the Company’s 2025 Form 10-K Annual Report.
Furthermore, the Company makes investments in entities that sponsor affordable housing projects. Similarly, for these non-consolidated VIEs, the Company has determined it is not the primary beneficiary as it has no ability to direct activities that could significantly affect the economic performance of the investments. The Company applies the proportional amortization method to subsequently measure its investments in such qualified affordable housing projects, where costs are amortized over the period in which the investor expects to receive tax credits and the resulting amortization is recognized as a component of income tax expense on the Company's Condensed Consolidated Statements of Operations. For the three and six months ended June 30, 2026, the Company recognized amortization of $7 and $13, respectively, and related tax benefits of $10 and $19. For the three and six months ended June 30, 2025, the Company recognized amortization of $4 and $8, respectively, and related tax benefits of $7 and $13, respectively. The income tax credits and other income tax benefits are recognized in operating activities in the Condensed Consolidated Statement of Cash Flows. The carrying value of these investments, which are reported in other assets on the Company’s Condensed Consolidated Balance Sheets was $166 and $121 as of June 30, 2026, and December 31, 2025, respectively. As of June 30, 2026 and December 31, 2025, the Company has outstanding commitments related to affordable housing projects of $199 and $259, respectively, that are contingent on various conditions precedent to funding.
In addition, the Company makes passive investments in structured securities issued by VIEs for which the Company is not the manager. These investments are included in ABS, CLOs, CMBS, and RMBS and are reported in fixed maturities, AFS, and FVO securities on the Company's Condensed Consolidated Balance Sheets. The Company has not provided financial or other support with respect to these investments other than its original investment. For these investments, the Company determined it is not the primary beneficiary due to the relative size of the Company’s investment in comparison to the principal amount of the structured securities issued by the VIEs, the Company’s inability to direct the activities that most significantly impact the economic performance of the VIEs, and, where applicable, the level of credit subordination which reduces the Company’s obligation to absorb losses or right to receive benefits. The Company’s maximum exposure to loss on these investments is limited to the amount of the Company’s investment.
Reverse Repurchase Agreements, Collateral Transactions and Restricted Investments
Reverse Repurchase Agreements
The Company enters into reverse repurchase agreements where the Company purchases securities and simultaneously agrees to resell the same or substantially the same securities. The maturity of these transactions is generally within one year. The agreements require additional collateral to be transferred to the Company under specified conditions and the Company has the right to sell or re-pledge the securities received. The Company accounts for reverse repurchase agreements as collateralized financing. As of June 30, 2026 and December 31, 2025, the Company reported $287 and $87, respectively, within short-term investments on the Condensed Consolidated Balance Sheets representing a receivable for the amount of cash transferred to purchase securities.
Collateral Transactions
For disclosure of collateral in support of derivative transactions, refer to the Derivative Collateral Arrangements section in Note 6 - Derivatives of Notes to Condensed Consolidated Financial Statements.
Other Restricted Investments
The Company is required by law to deposit securities with government agencies in certain states in which it conducts business. In addition, the Company is required to hold fixed maturities and short-term investments in trust for the benefit of syndicate policyholders, hold fixed maturities in a Lloyd's of London ("Lloyd's") trust account to provide a portion of the required capital, and maintain other investments primarily consisting of overseas deposits in various countries with Lloyd's to support underwriting activities in those countries. Lloyd's is an insurance market-place operating worldwide. Lloyd's does not underwrite risks. The Company accepts risks as the sole member of Lloyd's Syndicate 1221 ("Lloyd's Syndicate").

Derivative Instruments and Hedging Activities Disclosure [Abstract]  
Derivatives Instruments
6. Derivatives
The Company utilizes a variety of OTC, OTC-cleared and exchange traded derivative instruments as a part of its overall risk management strategy as well as to enter into replication transactions or income generation covered call transactions. Derivative instruments are used to manage risk associated with interest rate, equity market, credit spread, issuer default, price, and currency exchange rate or volatility. Replication transactions may be used as an economical means to synthetically replicate the characteristics and performance of assets that are permissible investments under the Company’s investment policies.
Strategies that Qualify for Hedge Accounting
Some of the Company's derivatives satisfy hedge accounting requirements as outlined in Note 1 - Basis of Presentation and Significant Accounting Policies of Notes to Consolidated Financial Statements, included in The Hartford’s 2025 Form 10-K Annual Report. Typically, these hedging instruments include interest rate swaps and, to a lesser extent, foreign currency swaps where the terms or expected cash flows of the hedged item closely match the terms of the swap.
Cash Flow Hedges
Interest rate swaps are predominantly used to manage portfolio duration and better match cash receipts from assets with cash disbursements required to fund liabilities. These derivatives primarily convert interest receipts on variable-rate fixed maturity securities to fixed rates. The Company has also entered into interest rate swaps to convert the variable interest payments on the $500 junior subordinated debentures due 2067 to fixed interest payments. For further information, see the Junior Subordinated Debentures section within Note 13 - Debt of Notes to Consolidated Financial Statements, included in The Hartford's 2025 Form 10-K Annual Report.
Foreign currency swaps are used to convert foreign currency denominated cash flows related to certain investment receipts to U.S. dollars in order to reduce cash flow fluctuations due to changes in currency rates.
Non-qualifying Strategies
Derivative relationships that do not qualify for hedge accounting (“non-qualifying strategies”) primarily include hedges of interest rate, foreign currency, and equity risk of certain fixed maturities and equities. In addition, hedging and replication strategies that utilize credit default swaps do not qualify for hedge accounting. The non-qualifying strategies include:
Credit Contracts
Credit default swaps are used to purchase credit protection on an individual entity or referenced index to economically hedge against default risk and credit-related changes in the value of fixed maturity securities. Credit default swaps are also used to assume credit risk related to an individual entity or referenced index as a part of replication transactions. These contracts require the Company to pay or receive a periodic fee in exchange for compensation from the counterparty or the Company should the referenced security issuers experience a credit event, as defined in the contract. The Company also enters into credit default swaps to terminate existing credit default swaps, thereby offsetting the changes in value of the original swap going forward.
Interest Rate Swaps and Futures
The Company uses interest rate swaps and, to a lesser extent, futures to manage interest rate duration between assets and liabilities. In addition, the Company enters into interest rate swaps to terminate existing swaps, thereby offsetting the changes in value of the original swap going forward. As of June 30, 2026 and December 31, 2025, the notional amount of interest rate swaps in offsetting relationships was $333 for both periods.
Foreign Currency Swaps
The Company enters into foreign currency swaps to convert the foreign currency exposures of certain foreign currency-denominated fixed maturity investments to U.S. dollars.
Equity Index Options
The Company may enter into equity index options to hedge the impact of a decline in the equity markets on the investment portfolio.
Derivative Balance Sheet Classification
For reporting purposes, the Company has elected to offset within assets or liabilities based upon the net of 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. The following fair value amounts do not include income accruals or related cash collateral receivables and payables, which are netted with derivative fair value amounts to determine balance sheet presentation. The Company’s derivative instruments are held for risk management purposes, unless otherwise noted in the following table. The notional amount of derivative contracts represents the basis upon which payments or receipts are calculated and is presented in the table to quantify the volume of the Company’s derivative activity. Notional amounts are not necessarily reflective of credit risk.

Offsetting of Derivative Assets/Liabilities
The following tables present the gross fair value amounts, the offsetting amounts, and net position of derivative instruments eligible for offset in the Company's Condensed Consolidated Balance Sheets. Offsetting amounts include fair value amounts, income accruals and related cash collateral receivables and payables associated with derivative instruments that are traded under a common master netting agreement, as described in the preceding discussion. Also included in the tables are financial collateral receivables and payables, which are contractually permitted to be offset upon an event of default, although are disallowed for offsetting under U.S. GAAP.

Cash Flow Hedges
For derivative instruments that are designated and qualify as cash flow hedges, the gain or loss on the derivative is reported as a component of OCI and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. All components of each derivative’s gain or loss were included in the assessment of hedge effectiveness.

As of June 30, 2026, the before tax deferred net losses on derivative instruments recorded in AOCI that are expected to be reclassified to earnings during the next twelve months are $2. This expectation is based on the anticipated interest payments on hedged investments in fixed maturity securities and long-term debt that will occur over the next twelve months. At that time, the Company will recognize the deferred net gains (losses) as an adjustment to net investment income or interest expense, as applicable, over the term of the hedged instrument cash flows.
During the three and six months ended June 30, 2026 and 2025, the Company had no net reclassifications from AOCI to earnings resulting from the discontinuance of cash-flow hedges due to forecasted transactions that were no longer probable of occurring.
Non-qualifying Strategies
For non-qualifying strategies, including embedded derivatives that are required to be bifurcated from their host contracts and accounted for as derivatives, the gain or loss on the derivative is recognized currently in earnings within net realized gains (losses).

Credit Risk Assumed through Credit Derivatives
The Company enters into credit default swaps that assume credit risk of a single entity or referenced index in order to synthetically replicate investment transactions that are permissible under the Company's investment policies. The Company will receive periodic payments based on an agreed upon rate and notional amount and will only make a payment if there is a credit event. A credit event payment will typically be equal to the notional value of the swap contract less the value of the referenced security issuer’s debt obligation after the occurrence of the credit event. A credit event is generally defined as a default on contractually obligated interest or principal payments or bankruptcy of the referenced entity. The credit default swaps in which the Company assumes credit risk may primarily reference investment grade single corporate issuers and baskets, which include standard diversified portfolios of corporate and CMBS issuers.

Derivative Collateral Arrangements
The Company enters into various collateral arrangements in connection with its derivative instruments, which require both the pledging and accepting of collateral. As of June 30, 2026 and December 31, 2025, the Company has pledged cash collateral associated with derivative instruments of $23 and $27, respectively. In general, collateral receivable is recorded in other assets or other liabilities on the Company's Condensed Consolidated Balance Sheets as determined by the Company's election to offset on the balance sheet. As of June 30, 2026 and December 31, 2025, the Company pledged securities collateral associated with derivative instruments with a fair value of $15 and $22, respectively, which have been included in fixed maturities on the Company's Condensed Consolidated Balance Sheets. The counterparties generally have the right to sell or re-pledge these securities.
In addition, as of June 30, 2026 and December 31, 2025, the Company has pledged initial margin of cash related to OTC-cleared and exchange traded derivatives with a fair value of $9 and $7, respectively, which is recorded in other investments or other assets on the Company's Condensed Consolidated Balance Sheets.
As of June 30, 2026 and December 31, 2025, the Company has pledged initial margin of securities related to OTC-cleared and exchange traded derivatives with a fair value of $257 and $98, respectively, which are included within fixed maturities on the Company's Condensed Consolidated Balance Sheets.
As of June 30, 2026 and December 31, 2025, the Company accepted cash collateral associated with derivative instruments of $49 and $50, respectively, which was invested and recorded in the Company's Condensed Consolidated Balance Sheets in fixed maturities and short-term investments with corresponding amounts recorded in other investments or other liabilities as determined by the Company's election to offset on the balance sheet. The Company also accepted securities collateral, as of June 30, 2026 and December 31, 2025, with a fair value of $10 and $2, respectively, which the Company has the right to repledge or sell. As of June 30, 2026 and December 31, 2025, the Company had no repledged securities. In addition, as of June 30, 2026 and December 31, 2025, non-cash collateral accepted was held in separate custodial accounts and was not included in the Company's Condensed Consolidated Balance Sheets.
Derivatives, Policy [Policy Text Block] For reporting purposes, the Company has elected to offset within assets or liabilities based upon the net of 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.

Re-estimates of prior accident year reserves for the six months ended June 30, 2026
Workers’ compensation reserves were decreased within accident years 2017 to 2021, driven by lower than previously estimated claim severity in small business.
General liability reserves were increased for the three months ended March 31, 2026 to reflect legacy sexual molestation and sexual abuse exposures related to polices written in the 1970s and 1980s, which includes a provision for a settlement in principle in one bankruptcy proceeding involving a religious institution. In addition, reserves were increased for the three months ended June 30, 2026, primarily to reflect a higher frequency of large losses in excess casualty and umbrella lines across multiple accident years.
Commercial property reserves were decreased within accident years 2021 to 2025 as a result of lower than expected severity.
Bond reserves were decreased primarily due to favorable development on commercial and contract surety and fidelity bonds driven by accident years 2022 and prior.
Commercial automobile liability reserves were increased primarily due to adverse loss development within accident years 2023 and 2024, driven by higher severity than previously estimated.
Personal automobile liability reserves were decreased primarily within accident years 2021 to 2024 as a result of lower than expected severity and lower estimated allocated loss adjustment expenses.
Homeowners reserves were decreased primarily due to favorable severity impacting accident years 2023 to 2025.
Catastrophe reserves were decreased across Business Insurance and Personal Insurance, primarily within accident years 2021 to 2024, driven by lower than expected development on hail and hurricane claims.
Other reserve re-estimates, net, were decreased due to lower than expected severity on Personal Insurance automobile physical damage for accident year 2025, partially offset by unfavorable development from participation in involuntary market pools.
Re-estimates of prior accident year reserves for the six months ended June 30, 2025
Workers’ compensation reserves were decreased within the 2016 to 2021 accident years primarily in small business, driven by lower than previously estimated claim severity.
Commercial property reserves were decreased primarily within accident years 2023 and 2024 as a result of lower than expected severity.
Professional liability reserves were decreased due to favorable development on directors and officers ("D&O") claims driven by the 2020 to 2023 accident years, partially offset by deterioration in employment practices liability and errors and omissions ("E&O") claims across multiple accident years.
Bond reserves decreased due primarily to favorable development on commercial and contract surety bonds driven by accident years 2019 to 2021.
Personal automobile liability reserves were decreased primarily within accident years 2020 to 2023 as a result of lower than expected severity.
Homeowners reserves were decreased primarily due to favorable severity impacting accident year 2024.
Catastrophes reserves were decreased across Business Insurance and Personal Insurance primarily driven by a reduction in reserves in accident years 2021 to 2024, including favorable emergence related to various hail events.
Other reserve re-estimates, net, were decreased due to lower than expected severity on Personal Insurance automobile physical damage for accident year 2024, partially offset by unfavorable development from participation in involuntary market pools.
Change in Deferred Gain on Retroactive Reinsurance
The Company has two ADC reinsurance agreements with National Indemnity Company ("NICO"), a subsidiary of Berkshire Hathaway Inc., both accounted for as retroactive reinsurance. One agreement covered substantially all asbestos and environmental ("A&E") reserve development for accident years prior to 2016 up to an aggregate limit of $1.5 billion and the other covered substantially all reserve development of Navigators Insurance Company and certain of its affiliates for 2018 and prior accident years up to an aggregate limit of $300. The Company had previously ceded all available limits under the agreements. As such, no remaining limit was available under the A&E ADC as of December 31, 2025, and no remaining limit was available under the Navigators' ADC as of December 31, 2023.
During the three months ended March 31, 2026, the Company collected recoveries from NICO under the A&E ADC and, as a result, amortized $36 of the deferred gain within benefits, losses and loss adjustment expenses. Subsequently during the first quarter of 2026, NICO suspended any further payment under the A&E ADC due to a dispute that is the subject of an arbitration proceeding. The timing of any resolution or outcome of the arbitration is not yet known and there may be impacts to the Company's cash flows or operating results as a result of the dispute. The deferred gain on the A&E ADC was $814 and $850, as of June 30, 2026 and December 31, 2025, respectively, and is included in other liabilities on the Condensed Consolidated Balance Sheets.
During the three and six months ended June 30, 2025, the Company collected recoveries from NICO under the Navigators ADC and, as a result, amortized $24 and $56 of the deferred gain within benefits, losses and loss adjustment expenses. As of September 30, 2025, the deferred gain on the Navigators ADC had been fully amortized and the limit fully collected.

Re-estimates of prior incurral years reserves for the six months ended June 30, 2026
Group disability - Prior period reserve estimates decreased by approximately $227 driven by favorable long-term disability claim recoveries and a higher New York paid family leave risk adjustment benefit than expected.
Group life and accident (including group life premium waiver) - Prior period reserve estimates decreased by approximately $55 driven by favorable mortality emergence in both group term life and group accidental death and dismemberment, and continued low incidence in group life premium waiver.
Re-estimates of prior incurral years reserves for the six months ended June 30, 2025
Group disability- Prior period reserve estimates decreased by approximately $307 driven by strong long-term disability claim recoveries, paid family medical leave incidence lower than prior assumptions, as well as a higher New York paid family leave risk adjustment benefit than expected.
Group life and accident (including group life premium waiver)- Prior period reserve estimates decreased by approximately $69 driven by favorable mortality emergence in both group term life and group accidental death and dismemberment, and continued low incidence in group life premium waiver.

12. Income Taxes
The effective tax rate was 20.4% and 19.7% for the three and six months ended June 30, 2026 and 20.1% and 19.8% for the three and six months ended June 30, 2025, respectively. The effective tax rate differs from the U.S. federal statutory tax rate of 21% primarily due to net excess tax benefits on stock-based compensation, tax credits and non-taxable net investment income.
The Company's effective tax rate is based on income from continuing operations. See Note 17 - Discontinued Operations of Notes to Condensed Consolidated Financial Statements for information on tax impacts from discontinued operations.

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]  
Commitments and Contingencies Disclosure [Text Block]
13. 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.
Litigation
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 and benefits 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, 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 individual and class actions, some of which assert claims for substantial amounts. Individual actions may include claims alleging bad faith in the handling of insurance claims or other allegedly unfair or improper business practices and may seek punitive damages. In putative class actions, plaintiffs may be seeking certification of a state or national class and 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. 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 allegedly 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 A&E 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, new targets, 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.
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. 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.
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 June 30, 2026, the Company reported $281 of net A&E reserves, net of the benefit of losses ceded to the A&E ADC with NICO. 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. For more information on the A&E ADC, refer to Note 9 - Reserve for Unpaid Losses and Loss Adjustment Expenses of Notes to Condensed Consolidated Financial Statements and Note 10 - Reserve for Unpaid Losses and Loss Adjustment Expenses of Notes to Consolidated Financial Statements included in the Company's 2025 Form 10-K Annual Report.
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 rating organizations, 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 June 30, 2026 was $47 for which the legal entities have posted collateral of $38 in the normal course of business. Based on derivative contractual terms as of June 30, 2026, 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.

Equity Repurchase Program
During the six months ended June 30, 2026 and 2025, the Company repurchased $900 (6.7 million shares) and $800 (6.8 million shares), respectively, of common stock under Board authorized share repurchase programs covering the applicable periods. As of June 30, 2026, the Company has $648 remaining for equity repurchases under the current $3.3 billion share repurchase program, which is effective until December 31, 2026. During the period July 1, 2026 through July 22, 2026, the Company repurchased $109 (0.8 million common shares) under this repurchase program.
In addition to the authorization covering the period from August 1, 2024 to December 31, 2026, the Board of Directors approved a share repurchase authorization for up to $4.2 billion effective from August 1, 2026 to December 31, 2028. The timing of any repurchases of shares is dependent on several factors, including the market price of the Company's securities, the Company's capital position, consideration of the effect of any repurchases on the Company's financial strength or credit ratings, the Company's blackout periods, and other considerations

Sale of Hartford Funds Business
On June 3, 2026, the Company and Wellington Management ("Wellington") entered into a definitive agreement under which Wellington will acquire Hartford Funds Management Group, Inc. ("Hartford Funds"), a subsidiary of Hartford Holdings, Inc. This transaction represents an exit from the Company's mutual fund, exchange-traded funds and third-party life and annuity separate account asset management business. Under the terms of the agreement, Wellington will operate Hartford Funds and serve as investment advisor to all funds following closing.
Transaction consideration consists of $300 of cash payable at closing and contingent consideration in the form of quarterly payments representing 95% of after tax available cash generated by the combination of Hartford Funds’ business and Wellington’s business supporting Hartford Funds, including the sale of certain other Wellington-sponsored products in the U.S. wealth market, for an expected period of seven years following closing, which period may be shortened or extended based on specified performance thresholds. Beginning five years after closing, if the net present value ("NPV") of the quarterly cash flows, discounted at 11%, together with the upfront proceeds, equals or exceeds $2.1 billion, quarterly payment obligations will terminate. If, at the end of the initial seven-year period, the NPV of the quarterly cash flows, discounted at 11%, together with the upfront proceeds, is less than $1.5 billion, quarterly payments will continue until the earlier of the quarter in which the $1.5 billion threshold is met or the end of eight additional quarters.
During the term of the contingent consideration, the Company will retain certain limited protective and information rights designed to preserve the value of the contingent payments; however, such rights do not provide the Company with the ability to direct the activities that most significantly impact the economic performance of the business. In addition, the Company expects to provide transition services for a limited period following closing.
Upon being classified as held for sale, the Hartford Funds reporting unit goodwill of $272 was tested for impairment. The
fair value of the reporting unit significantly exceeded its carrying value; therefore, no impairment was recognized. The estimated fair value incorporates multiple inputs into discounted cash flow calculations including assumptions that market participants would make in valuing the reporting unit. Assumptions include projected growth, earnings forecasts, assets under management, and the weighted average cost of capital used for the purposes of discounting.
Upon being classified as held for sale in the second quarter of 2026, the Company recognized a $251 deferred tax asset and related income tax benefit within discontinued operations associated with the transaction representing the difference between the tax basis and U.S. GAAP carrying value of Hartford Funds.
Prior to closing, the Company expects to receive a pre-closing dividend of approximately $170 from Hartford Funds, subject to market and operating performance through closing.
At closing, the Company expects to recognize an estimated after tax realized loss of approximately $150 in discontinued operations, reflecting the difference between the carrying value of Hartford Funds and the cash consideration recognized upon deconsolidation, subject to future operating performance and market conditions. The Company will account for the contingent consideration as a gain contingency, which is not deemed realizable until it is received, and therefore is not recognized on the closing date. Following closing, contingent consideration payments will be made to the Company on a quarterly basis and recognized in net income in the period received.
The transaction is expected to close in the first quarter of 2027, subject to customary closing conditions, including regulatory and fund approvals. Hartford Funds has met the criteria for reporting as discontinued operations and is reported in the Corporate category until closing.

Basis of Presentation
The Hartford Insurance Group, Inc. is a holding company for subsidiaries that primarily provide property and casualty insurance, and employee group benefits insurance and services, 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”).
On June 3, 2026, the Company entered into a definitive agreement to sell Hartford Funds Management Group, Inc. ("Hartford Funds"), a subsidiary of Hartford Holdings, Inc. For further discussion of this transaction, see Note 17 - Discontinued Operations of Notes to Condensed Consolidated Financial Statements.
The Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information, which differ materially from the accounting practices prescribed by various insurance regulatory authorities. These Condensed Consolidated Financial Statements and Notes should be read in conjunction with the Consolidated Financial Statements and Notes thereto included in the Company's 2025 Form 10-K Annual Report. The results of operations for interim periods are not necessarily indicative of the results that may be expected for the full year.
The accompanying Condensed Consolidated Financial Statements and Notes are unaudited. These financial statements reflect all adjustments (generally consisting only of normal accruals) which are, in the opinion of management, necessary for the fair statement of the financial position, results of operations and cash flows for the interim periods.

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
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.
Commitments and Contingencies, Policy [Policy Text Block]
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.
Fair Value Measurement, Policy
The Company carries certain financial assets and liabilities at estimated fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants. Our fair value framework includes a hierarchy that gives the highest priority to the use of quoted prices in active markets, followed by the use of market observable inputs, followed by the use of unobservable inputs.
The fair value hierarchy levels are as follows:
Level 1    Fair values based on unadjusted quoted prices for identical assets or liabilities, in active markets that the Company has the ability to access at the measurement date.
Level 2    Fair values primarily based on observable inputs, other than quoted prices included in Level 1, or based on prices for similar assets and liabilities.
Level 3    Fair values derived when one or more of the significant inputs are unobservable (including assumptions about risk). With little or no observable market, the determination of fair values uses considerable judgment and represents the Company’s best estimate of an amount that could be realized in a market exchange for the asset or liability. Also included are securities that are traded within illiquid markets and/or priced by independent brokers.
The Company will classify the financial asset or liability by level based upon the lowest level input that is significant to the determination of the fair value. In most cases, both observable inputs (e.g., changes in interest rates) and unobservable inputs (e.g., changes in risk assumptions) are used to determine fair values that the Company has classified within Level 3.
Fair Value of Financial Instruments, Policy [Policy Text Block]
Valuation Techniques
The Company generally determines fair values using valuation techniques that use prices, rates, and other relevant information evident from market transactions involving identical or similar
instruments. Valuation techniques also include, where appropriate, estimates of future cash flows that are converted into a single discounted amount using current market expectations. The Company uses a "waterfall" approach comprised of the following pricing sources and techniques, which are listed in priority order:
•Quoted prices, unadjusted, for identical assets or liabilities in active markets, which are classified as Level 1.
•Prices from third-party pricing services, which primarily utilize a combination of techniques. These services utilize recently reported trades of identical, similar, or benchmark securities making adjustments for market observable inputs available through the reporting date. If there are no recently reported trades, they may use a discounted cash flow technique to develop a price using expected cash flows
based upon the anticipated future performance of the underlying collateral discounted at an estimated market rate. Both techniques develop prices that consider the time value of future cash flows and provide a margin for risk, including liquidity and credit risk. Most prices provided by third-party pricing services are classified as Level 2 because the inputs used in pricing the securities are observable. However, some securities that are less liquid or trade less actively are classified as Level 3. Additionally, certain long-dated securities include benchmark interest rate or credit spread assumptions that are not observable in the marketplace and are thus classified as Level 3.
•Internal matrix pricing is a valuation process internally developed for private placement securities for which the Company is unable to obtain a price from a third-party pricing service. Internal pricing matrices determine credit spreads that, when combined with risk-free rates, are applied to contractual cash flows to develop a price. The Company develops credit spreads using market based data for public securities adjusted for credit spread differentials between public and private securities, which are obtained from a survey of multiple private placement brokers. The market-based reference credit spread considers the issuer’s sector, financial strength, and term to maturity, using an independent public security index, while the credit spread differential considers the non-public nature of the security. Securities priced using internal matrix pricing are classified as Level 2 because the significant inputs are observable or can be corroborated with observable data.
•Independent broker quotes, which are typically non-binding, use inputs that can be difficult to corroborate with observable market-based data. Brokers may use present value techniques using assumptions specific to the security types, or they may use recent transactions of similar securities. Due to the lack of transparency in the process that brokers use to develop prices, valuations that are based on independent broker quotes are classified as Level 3. As of June 30, 2026 and December 31, 2025, no significant adjustments were made by the Company to broker prices received.
•Internal valuation models are used when third-party pricing or independent broker quotes are not available. These internally developed models incorporate market-based credit spreads from independent public security indexes reflective of comparable quality, maturity, and sector, adjusted for the non-public nature of the security. These securities are classified as Level 3 since they are not observable in the marketplace.
The fair value of derivative instruments is determined primarily using a discounted cash flow model or option model technique and incorporates counterparty credit risk. In some cases, quoted market prices for exchange-traded and over-the-counter ("OTC") cleared derivatives may be used and in other cases independent broker quotes may be used. The pricing valuation models primarily use inputs that are observable in the market or can be corroborated by observable market data. The valuation of certain derivatives may include significant inputs that are unobservable, such as volatility levels, and reflect the Company’s view of what other market participants would use when pricing such instruments.
Valuation Controls
The process for determining the fair value of investments is monitored by the Valuation Committee, which is a cross-functional group of senior management within the Company. The purpose of the Valuation Committee is to provide oversight of the pricing policy, procedures, and controls, including approval of valuation methodologies and pricing sources. The Valuation Committee reviews market data trends, pricing statistics and trading statistics to ensure that prices are reasonable and consistent with our fair value framework. Controls and procedures used to assess third-party pricing services are reviewed by the Valuation Committee, including the results of annual due-diligence reviews. Controls include, but are not limited to, reviewing daily and monthly price changes, stale prices, and missing prices and comparing new trade prices to third-party pricing services, weekly price changes to published bond index prices, and daily OTC derivative market valuations to counterparty valuations. The Company has a dedicated pricing group that works with trading and investment professionals to challenge prices received by a third-party pricing source if the Company believes that the valuation received does not accurately reflect the fair value. New valuation models and changes to current models require approval by the Valuation Committee. In addition, the Company’s enterprise-wide Operational Risk Management function provides an independent review of the suitability and reliability of model inputs, as well as an analysis of significant changes to current models.
Valuation Inputs
Quoted prices for identical assets in active markets are considered Level 1 and consist of on-the-run U.S. Treasuries, money market funds, exchange-traded equity securities, open-ended mutual funds, certain short-term investments, and exchange traded derivative instruments.

Reclassification, Comparability Adjustment
Reclassifications
Certain reclassifications have been made to prior period financial information to conform to the current period presentation. In particular, prior period results of operations associated with the Company's Hartford Funds business have been retrospectively reclassified to discontinued operations and assets and liabilities associated with the Hartford Funds business are classified as assets and liabilities held for sale within the Corporate category.
Discontinued Operations, Policy
Discontinued Operations
The results of operations of a component of the Company are reported in discontinued operations when certain criteria are met as of the date of disposal, or earlier if classified as held-for-sale. When a component is identified for discontinued operations reporting, amounts for prior periods are retrospectively reclassified as discontinued operations. Components are identified as discontinued operations if they are a major part of an entity's operations and financial results such as a separate major line of business or a separate major geographical area of operations. Hartford Funds has met the criteria for reporting as discontinued operations and is reported in the Corporate category until closing.

[1]The weighted average is determined based on the fair value of the securities.
[2]Conversely, the impact of a decrease in input would have the opposite impact to the fair value as that presented in the table.
[3]Excludes securities for which the Company bases fair value on broker quotations.
[4]Excludes securities for which the Company bases fair value on broker quotations; however, included are broker priced lower-rated private placement securities for which the Company receives spread and yield information to corroborate the fair value.
[5]Decrease for above market rate coupons and increase for below market rate coupons.
[6]Generally, a change in the assumption used for the constant default rate would have been accompanied by a directionally similar change in the assumption used for the loss severity and a directionally opposite change in the assumption used for constant prepayment rate and would have resulted in wider spreads.
The table above excludes certain securities for which fair values are predominately based on independent broker quotes. As of June 30, 2026 and December 31, 2025, the fair values of the Company's level 3 derivatives were less than $1 for both periods.
