General [Abstract]
General	Note 1 General Basis of presentation The accompanying condensed consolidated financial statements include the accounts of The Allstate Corporation (the “Corporation”) and its wholly owned subsidiaries, primarily Allstate Insurance Company (“AIC”), a property and casualty insurance company (collectively referred to as the “Company” or “Allstate”) and variable interest entities (“VIEs”) in which the Company is considered a primary beneficiary. These condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The condensed consolidated financial statements and notes as of March 31, 2023 and for the three month periods ended March 31, 2023 and 2022 are unaudited. The condensed consolidated financial statements reflect all adjustments (consisting only of normal recurring accruals) which are, in the opinion of management, necessary for the fair presentation of the financial position, results of operations and cash flows for the interim periods. 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 annual report on Form 10-K for the year ended December 31, 2022. The results of operations for the interim periods should not be considered indicative of results to be expected for the full year. All significant intercompany accounts and transactions have been eliminated. To reflect the application of the new guidance to all in-scope long-duration insurance contracts, certain amounts in the condensed consolidated financial statements and notes for 2022 have been recast. Macroeconomic impacts The Novel Coronavirus Pandemic or COVID-19 (“Coronavirus”) and subsequent U.S. government fiscal and monetary policies have and may continue to effect economic activity through longer-term impacts such as supply chain disruptions, labor shortages and other macroeconomic factors that have increased inflation and affected our operations. These factors may continue to significantly affect results of operations, financial condition and liquidity. The impact from the pandemic and the ongoing effects should be considered when comparing the current period to prior periods. Adopted accounting standard Accounting for Long-Duration Insurance Contracts Effective January 1, 2023, the Company adopted the Financial Accounting Standards Board (”FASB”) guidance revising the accounting for certain long-duration insurance contracts using the modified retrospective approach to the transition date of January 1, 2021. Under the new guidance, measurement assumptions, including those for mortality, morbidity and policy lapses, are required to be reviewed at least annually, and updated as appropriate. In addition, reserves under the new guidance are required to be discounted using an upper-medium grade fixed income instrument yield that is updated through other comprehensive income (“OCI”) at each reporting date. Additionally, deferred policy acquisition costs (“DAC”) for all long-duration products will be amortized on a simplified basis. Also, the Company’s reserve for future policy benefits and DAC will be subject to new disclosure guidance. In addition, the Company met the conditions included in Accounting Standards Update No. 2022-05, Transition for Sold Contracts , and elected to not apply the new guidance for contracts that were part of the 2021 sales of Allstate Life Insurance Company (“ALIC”) and Allstate Life Insurance Company of New York (“ALNY”). After-tax cumulative effect of change in accounting principle on transition date ($ in millions) January 1, 2021 Decrease in retained income $ 21 Decrease in accumulated other comprehensive income (“AOCI”) 277 Total decrease in equity $ 298 The decrease in AOCI is primarily attributable to a change in the discount rate used in measuring the reserve for future policy benefits for traditional life contracts and other long-term products with guaranteed terms from a portfolio-based rate at contract issuance to an upper-medium grade fixed income-based rate at the reporting date. The decrease in retained income primarily relates to certain cohorts of long-term contracts whose expected net premiums exceeded expected gross premiums which resulted in an increase in reserves and a decrease in retained income equal to the present value of expected future benefits less the present value of expected future premiums at the transition date. Transition disclosures The following tables summarize the balance of and changes in the reserve for future policy benefits and DAC on January 1, 2021 upon the adoption of the guidance. Impact of adoption for reserve for future policy benefits ( $ in millions) Accident and health Traditional life Total Pre-adoption 12/31/2020 balance (1) $ 728 $ 311 $ 1,039 Adjustments: Effect of the remeasurement of the reserve at upper-medium grade fixed income-based rate (2) 232 153 385 Adjustments for contracts with net premiums in excess of gross premiums (3) 77 — 77 Total adjustments 309 153 462 Post-adoption 1/1/2021 balance 1,037 464 1,501 Less: reinsurance recoverables (4) 159 3 162 Post-adoption 1/1/2021 balance, after reinsurance recoverables $ 878 $ 461 $ 1,339 (1) Traditional life includes $11 million in reserves related to riders of traditional life insurance products reclassified from contractholder funds. (2) Adjustment reflected with a corresponding decrease to AOCI. (3) Adjustment reflected with a corresponding decrease to retained income. (4) Represents post-adoption January 1, 2021 balance of reinsurance recoverables. Adjustments to reinsurance recoverables for accident and health products increased January 1, 2021 AOCI by $33 million due to the remeasurement of the reserve at upper-medium grade fixed income based rate and increased January 1, 2021 retained income by $51 million due to adjustments for contracts with net premiums in excess of gross premiums. Impact of adoption for DAC ( $ in millions) Accident and health Traditional life Interest- sensitive life Total Pre-adoption 12/31/2020 balance $ 343 $ 32 $ 95 $ 470 Adjustment for removal of impact of unrealized gains or losses (1) — — 2 2 Post-adoption 1/1/2021 balance $ 343 $ 32 $ 97 $ 472 (1) Adjustment reflected with a corresponding increase to AOCI.

Under the net premium reserving model, the Company computes a net premium ratio which is the present value of insurance contract benefits divided by the present value of gross premiums. The present value of contract benefits and gross premiums are determined using the discount rate at contract inception. The net premium ratio is applied to premiums due on a periodic basis to compute the RFPB. The net premium ratio is recomputed at least annually using both actual historical cash flows and future cash flows anticipated over the life of cohort of contracts subject to measurement. Assumptions including mortality, morbidity, and lapses affect the timing and amount of estimated cash flows used to calculate the RFPB. The Company has grouped contracts into cohorts based on product type and issue year. Examples of insurance product types include whole life, term life, critical illness and disability. Issue year is based on the issuance date of the contract to the policyholder, except in the case of contracts acquired in a business combination, where the issue date is based on the acquisition date of the business combination. The RFPB is calculated for contracts in force at the end of each period, which results in the Company recognizing the effects of actual experience in the period it occurs. Annually, in the third quarter, the Company obtains historical premiums and benefits information and evaluates future cash flow assumptions that include mortality, morbidity, and terminations, and updates cash flow assumptions as necessary. The Company has elected to not update the expense assumption when annually reviewing and updating future cash flow assumptions. Actual premiums and benefits and any updates to future cash flow assumptions are incorporated into the calculation of an updated net premium ratio. Updates for actual premiums and benefits and changes to future cash flow assumptions will result in a liability remeasurement gain or loss that is recognized in net income. The first step to determining the liability remeasurement gain or loss is to calculate the RFPB using revised net premiums discounted at the locked-in discount rate set at contract issuance. The result of the first step is then compared to the carrying amount of the RFPB before the updates for actual experience and changes to future cash flow assumptions. The decrease (gain) or increase (loss) in the RFPB is reported as liability remeasurement gain or loss in net income and presented parenthetically as part of Accident, health and other policy benefits on the Consolidated Statements of Operations. The updated net premium ratio is used in future quarters to measure the RFPB until the next annual update or an earlier date if the Company determines it is necessary to revise future cash flow assumptions based on available evidence, including actual experience . The discount rate assumption is determined using a yield curve approach. The yield curve consists of U.S. dollar-denominated senior unsecured fixed-income securities issued by U.S. companies that have an A credit rating based on the ratings provided by nationally recognized rating agencies that include Moody’s, Standard & Poor’s, and Fitch. For points on the yield curve that do not have observable yields, the Company uses linear interpolation w hich calculates the unobservable yield based on the two nearest observable yields, except for any points beyond the last observable yield at 30 years, where interest rates are held constant with the last observable point on the yield curve. The Company updates the current discount rate quarterly and the change in the RFPB resulting from the updated current discount rate is recognized in OCI. Deferred policy acquisition costs Deferred policy acquisition costs are related directly to the successful acquisition of new or renewal insurance contracts and are deferred and recognized as an expense over the life of the related contracts. These costs are principally agent and broker remuneration, premium taxes and certain underwriting expenses. All other acquisition costs are expensed as incurred and included in operating costs and expenses . Long-duration voluntary accident and health insurance, traditional life insurance contracts, and interest-sensitive life insurance contracts Voluntary accident and health insurance and traditional life insurance contracts are grouped by product and issue year into cohorts consistent with the cohorts used to calculate the RFPB. Interest-sensitive life insurance contracts are grouped into cohorts by issue year, and the issue year is determined based on contract issue date. DAC is amortized on a constant level basis over the expected contract term and is included in Amortization of deferred policy acquisition costs on the Consolidated Statements of Operations. The constant level basis used for all cohorts is based on policies-in-force. The expected contract term and mortality, morbidity, and termination assumptions are used to calculate both DAC amortization and the RFPB. If actual contract terminations are greater than expected terminations for any cohort, each affected cohort’s DAC balance will be reduced in the current period based on the difference between the actual and expected terminations. No adjustments to DAC amortization are recorded if actual contract terminations are less than expected terminations for any cohort. If the Company makes an update to any of its mortality, morbidity, or termination assumptions, the Company will use the assumptions prospectively to amortize any cohort’s remaining DAC over the remaining expected contract term. The costs assigned to the right to receive future cash flows from certain business purchased from other insurers are also classified as DAC in the Consolidated Statements of Financial Position. The costs capitalized represent the present value of future profits expected to be earned over the lives of the contracts acquired. The Company amortizes the present value of future profits using the same methodology and assumptions as the amortization of DAC. The present value of future profits is subject to premium deficiency testing.

Earnings Per Share [Abstract]
Earnings per Common Share	Note 2 Earnings per Common Share Basic earnings per common share is computed using the weighted average number of common shares outstanding, including vested unissued participating restricted stock units. Diluted earnings per common share is computed using the weighted average number of common and dilutive potential common shares outstanding. For the Company, dilutive potential common shares consist of outstanding stock options, unvested non-participating restricted stock units and contingently issuable performance stock awards. The effect of dilutive potential common shares does not include the effect of options with an anti-dilutive effect on earnings per common share because their exercise prices exceed the average market price of Allstate common shares during the period or for which the unrecognized compensation cost would have an anti-dilutive effect.

Segment Reporting [Abstract]
Reportable Segments	Note 3 Reportable Segments Measuring segment profit or loss The measure of segment profit or loss used in evaluating performance is underwriting income for the Allstate Protection and Run-off Property-Liability segments and adjusted net income for the Protection Services, Allstate Health and Benefits and Corporate and Other segments. Underwriting income is calculated as premiums earned and other revenue, less claims and claims expenses (“losses”), amortization of DAC, operating costs and expenses, amortization or impairment of purchased intangibles and restructuring and related charges as determined using GAAP. Adjusted net income is net income (loss) applicable to common shareholders, excluding: • Net gains and losses on investments and derivatives • Pension and other postretirement remeasurement gains and losses • Amortization or impairment of purchased intangibles • Gain or loss on disposition • Adjustments for other significant non-recurring, infrequent or unusual items, when (a) the nature of the charge or gain is such that it is reasonably unlikely to recur within two years, or (b) there has been no similar charge or gain within the prior two years • Income tax expense or benefit on reconciling items A reconciliation of these measures to net income (loss) applicable to common shareholders is provided below.

For each fixed income security in an unrealized loss position, the Company assesses whether management with the appropriate authority has made the decision to sell or whether it is more likely than not the Company will be required to sell the security before recovery of the amortized cost basis for reasons such as liquidity, contractual or regulatory purposes. If a security meets either of these criteria, any existing credit loss allowance would be written-off against the amortized cost basis of the asset along with any remaining unrealized losses, with incremental losses recorded in earnings. If the Company has not made the decision to sell the fixed income security and it is not more likely than not the Company will be required to sell the fixed income security before recovery of its amortized cost basis, the Company evaluates whether it expects to receive cash flows sufficient to recover the entire amortized cost basis of the security. The Company calculates the estimated recovery value based on the best estimate of future cash flows considering past events, current conditions and reasonable and supportable forecasts. The estimated future cash flows are discounted at the security’s current effective rate and is compared to the amortized cost of the security. The determination of cash flow estimates is inherently subjective, and methodologies may vary depending on facts and circumstances specific to the security. All reasonably available information relevant to the collectability of the security is considered when developing the estimate of cash flows expected to be collected. That information generally includes, but is not limited to, the remaining payment terms of the security, prepayment speeds, the financial condition and future earnings potential of the issue or issuer, expected defaults, expected recoveries, the value of underlying collateral, origination vintage year, geographic concentration of underlying collateral, available reserves or escrows, current subordination levels, third-party guarantees and other credit enhancements. Other information, such as industry analyst reports and forecasts, credit ratings, financial condition of the bond insurer for insured fixed income securities, and other market data relevant to the realizability of contractual cash flows, may also be considered. The estimated fair value of collateral will be used to estimate recovery value if the Company determines that the security is dependent on the liquidation of collateral for ultimate settlement. If the Company does not expect to receive cash flows sufficient to recover the entire amortized cost basis of the fixed income security, a credit loss allowance is recorded in earnings for the shortfall in expected cash flows; however, the amortized cost, net of the credit loss allowance, may not be lower than the fair value of the security. The portion of the unrealized loss related to factors other than credit remains classified in AOCI. If the Company determines that the fixed income security does not have sufficient cash flow or other information to estimate a recovery value for the security, the Company may conclude that the entire decline in fair value is deemed to be credit related and the loss is recorded in earnings. When a security is sold or otherwise disposed or when the security is deemed uncollectible and written off, the Company removes amounts previously recognized in the credit loss allowance. Recoveries after write-offs are recognized when received. Accrued interest excluded from the amortized cost of fixed income securities totaled $400 million and $389 million as of March 31, 2023 and December 31, 2022, respectively, and is reported within the accrued investment income line of the Condensed Consolidated Statements of Financial Position. The Company monitors accrued interest and writes off amounts when they are not expected to be received. The Company’s portfolio monitoring process includes a quarterly review of all securities to identify instances where the fair value of a security compared to its amortized cost is below internally established thresholds. The process also includes the monitoring of other credit loss indicators such as ratings, ratings downgrades and payment defaults. The securities identified, in addition to other securities for which the Company may have a concern, are evaluated for potential credit losses using all reasonably available information relevant to the collectability or recovery of the security. Inherent in the Company’s evaluation of credit losses for these securities are assumptions and estimates about the financial condition and future earnings potential of the issue or issuer. Some of the factors that may be considered in evaluating whether a decline in fair value requires a credit loss allowance are: 1) the financial condition, near-term and long-term prospects of the issue or issuer, including relevant industry specific market conditions and trends, geographic location and implications of rating agency actions and offering prices; 2) the specific reasons that a security is in an unrealized loss position, including overall market conditions which could affect liquidity; and 3) the extent to which the fair value has been less than amortized cost.

(4) Evaluated based on factors such as discounted cash flows and the financial condition and near-term and long-term prospects of the issue or issuer and were determined to have adequate resources to fulfill contractual obligations. Investment grade is defined as a security having a National Association of Insurance Commissioners (“NAIC”) designation of 1 or 2, which is comparable to a rating of Aaa, Aa, A or Baa from Moody’s or AAA, AA, A or BBB from S&P Global Ratings (“S&P”), or a comparable internal rating if an externally provided rating is not available. Market prices for certain securities may have credit spreads which imply higher or lower credit quality than the current third-party rating. Unrealized losses on investment grade securities are principally related to an increase in market yields which may include increased risk-free interest rates or wider credit spreads since the time of initial purchase. The unrealized losses are expected to reverse as the securities approach maturity. ABS in an unrealized loss position were evaluated based on actual and projected collateral losses relative to the securities’ positions in the respective securitization trusts, security specific expectations of cash flows, and credit ratings. This evaluation also takes into consideration credit enhancement, measured in terms of (i) subordination from other classes of securities in the trust that are contractually obligated to absorb losses before the class of security the Company owns, and (ii) the expected impact of other structural features embedded in the securitization trust beneficial to the class of securities the Company owns, such as overcollateralization and excess spread. Municipal bonds in an unrealized loss position were evaluated based on the underlying credit quality of the primary obligor, obligation type and quality of the underlying assets. As of March 31, 2023, the Company has not made the decision to sell and it is not more likely than not the Company will be required to sell fixed income securities with unrealized losses before recovery of the amortized cost basis. Loans The Company establishes a credit loss allowance for mortgage loans and bank loans when they are originated or purchased, and for unfunded commitments unless they are unconditionally cancellable by the Company. The Company uses a probability of default and loss given default model for mortgage loans and bank loans to estimate current expected credit losses that considers all relevant information available including past events, current conditions, and reasonable and supportable forecasts over the life of an asset. The Company also considers such factors as historical losses, expected prepayments and various economic factors. For mortgage loans the Company considers origination vintage year and property level information such as debt service coverage, property type, property location and collateral value. For bank loans, the Company considers the credit rating of the borrower, credit spreads and type of loan. After the reasonable and supportable forecast period, the Company’s model reverts to historical loss trends. Loans are evaluated on a pooled basis when they share similar risk characteristics. The Company monitors loans through a quarterly credit monitoring process to determine when they no longer share similar risk characteristics and are to be evaluated individually when estimating credit losses. Loans are written off against their corresponding allowances when there is no reasonable expectation of recovery. If a loan recovers after a write-off, the estimate of expected credit losses includes the expected recovery. Accrual of income is suspended for loans that are in default or when full and timely collection of principal and interest payments is not probable. Accrued income receivable is monitored for recoverability and when not expected to be collected is written off through net investment income. Cash receipts on loans on non-accrual status are generally recorded as a reduction of amortized cost. Accrued interest is excluded from the amortized cost of loans and is reported within the accrued investment income line of the Condensed Consolidated Statements of Financial Position. Accrued interest ($ in millions) March 31, December 31, 2023 2022 Mortgage loans $ 3 $ 3 Bank Loans 4 3 Mortgage loans When it is determined a mortgage loan shall be evaluated individually, the Company uses various methods to estimate credit losses on individual loans such as using collateral value less estimated costs to sell where applicable, including when foreclosure is probable or when repayment is expected to be provided substantially through the operation or sale of the collateral and the borrower is experiencing financial difficulty. When collateral value is used, the mortgage loans may not have a credit loss allowance when the fair value of the collateral exceeds the loan’s amortized cost. An alternative approach may be utilized to estimate credit losses using the present value of the loan’s expected future repayment cash flows discounted at the loan’s current effective interest rate. Individual loan credit loss allowances are adjusted for subsequent changes in the fair value of the collateral less costs to sell, when applicable, or present value of the loan’s expected future repayment cash flows. Debt service coverage ratio is considered a key credit quality indicator when mortgage loan credit loss allowances are estimated.

Fair Value of Assets and Liabil

Fair Value of Assets and Liabilities	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value of Assets and Liabilities	Note 5 Fair Value of Assets and Liabilities Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The hierarchy for inputs used in determining fair value maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that observable inputs be used when available. Assets and liabilities recorded on the Condensed Consolidated Statements of Financial Position at fair value are categorized in the fair value hierarchy based on the observability of inputs to the valuation techniques as follows: Level 1: Assets and liabilities whose values are based on unadjusted quoted prices for identical assets or liabilities in an active market that the Company can access. Level 2: Assets and liabilities whose values are based on the following: (a) Quoted prices for similar assets or liabilities in active markets; (b) Quoted prices for identical or similar assets or liabilities in markets that are not active; or (c) Valuation models whose inputs are observable, directly or indirectly, for substantially the full term of the asset or liability. Level 3: Assets and liabilities whose values are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. Unobservable inputs reflect the Company’s estimates of the assumptions that market participants would use in valuing the assets and liabilities. The availability of observable inputs varies by instrument. In situations where fair value is based on internally developed pricing models or inputs that are unobservable in the market, the determination of fair value requires more judgment. The degree of judgment exercised by the Company in determining fair value is typically greatest for instruments categorized in Level 3. In many instances, valuation inputs used to measure fair value fall into different levels of the fair value hierarchy. The category level in the fair value hierarchy is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The Company uses prices and inputs that are current as of the measurement date, including during periods of market disruption. In periods of market disruption, the ability to observe prices and inputs may be reduced for many instruments. The Company is responsible for the determination of fair value and the supporting assumptions and methodologies. The Company gains assurance that assets and liabilities are appropriately valued through the execution of various processes and controls designed to ensure the overall reasonableness and consistent application of valuation methodologies, including inputs and assumptions, and compliance with accounting standards. For fair values received from third parties or internally estimated, the Company’s processes and controls are designed to ensure that the valuation methodologies are appropriate and consistently applied, the inputs and assumptions are reasonable and consistent with the objective of determining fair value, and the fair values are accurately recorded. For example, on a continuing basis, the Company assesses the reasonableness of individual fair values that have stale security prices or that exceed certain thresholds as compared to previous fair values received from valuation service providers or brokers or derived from internal models. The Company performs procedures to understand and assess the methodologies, processes and controls of valuation service providers. In addition, the Company may validate the reasonableness of fair values by comparing information obtained from valuation service providers or brokers to other third-party valuation sources for selected securities. The Company performs ongoing price validation procedures such as back-testing of actual sales, which corroborate the various inputs used in internal models to market observable data. When fair value determinations are expected to be more variable, the Company validates them through reviews by members of management who have relevant expertise and who are independent of those charged with executing investment transactions. The Company has two types of situations where investments are classified as Level 3 in the fair value hierarchy: (1) Specific inputs significant to the fair value estimation models are not market observable. This primarily occurs in the Company’s use of broker quotes to value certain securities where the inputs have not been corroborated to be market observable, and the use of valuation models that use significant non-market observable inputs. (2) Quotes continue to be received from independent third-party valuation service providers and all significant inputs are market observable; however, there has been a significant decrease in the volume and level of activity for the asset when compared to normal market activity such that the degree of market observability has declined to a point where categorization as a Level 3 measurement is considered appropriate. The indicators considered in determining whether a significant decrease in the volume and level of activity for a specific asset has occurred include the level of new issuances in the primary market, trading volume in the secondary market, the level of credit spreads over historical levels, applicable bid-ask spreads, and price consensus among market participants and other pricing sources. Certain assets are not carried at fair value on a recurring basis, including mortgage loans, bank loans and policy loans and are only included in the fair value hierarchy disclosure when the individual investment is reported at fair value. In determining fair value, the Company principally uses the market approach which generally utilizes market transaction data for the same or similar instruments. To a lesser extent, the Company uses the income approach which involves determining fair values from discounted cash flow methodologies. For the majority of Level 2 and Level 3 valuations, a combination of the market and income approaches is used. Summary of significant inputs and valuation techniques for Level 2 and Level 3 assets and liabilities measured at fair value on a recurring basis Level 2 measurements • Fixed income securities: U.S. government and agencies, municipal, corporate - public and foreign government: The primary inputs to the valuation include quoted prices for identical or similar assets in markets that are not active, contractual cash flows, benchmark yields and credit spreads. Corporate - privately placed: Privately placed are valued using a discounted cash flow model that is widely accepted in the financial services industry and uses market observable inputs and inputs derived principally from, or corroborated by, observable market data. The primary inputs to the discounted cash flow model include an interest rate yield curve, as well as published credit spreads for similar assets in markets that are not active that incorporate the credit quality and industry sector of the issuer. Corporate - privately placed also includes redeemable preferred stock that are valued using quoted prices for identical or similar assets in markets that are not active, contractual cash flows, benchmark yields, underlying stock prices and credit spreads. ABS: The primary inputs to the valuation include quoted prices for identical or similar assets in markets that are not active, contractual cash flows, benchmark yields, collateral performance and credit spreads. Certain ABS are valued based on non-binding broker quotes whose inputs have been corroborated to be market observable. Residential mortgage-backed securities (“MBS”), included in ABS, use prepayment speeds as a primary input for valuation. • Equity securities: The primary inputs to the valuation include quoted prices or quoted net asset values for identical or similar assets in markets that are not active. • Short-term: The primary inputs to the valuation include quoted prices for identical or similar assets in markets that are not active, contractual cash flows, benchmark yields and credit spreads. • Other investments: Free-standing exchange listed derivatives that are not actively traded are valued based on quoted prices for identical instruments in markets that are not active. Over-the-counter (“OTC”) derivatives, including interest rate swaps, foreign currency swaps, total return swaps, foreign exchange forward contracts, certain options and certain credit default swaps, are valued using models that rely on inputs such as interest rate yield curves, implied volatilities, index price levels, currency rates, and credit spreads that are observable for substantially the full term of the contract. The valuation techniques underlying the models are widely accepted in the financial services industry and do not involve significant judgment. Level 3 measurements • Fixed income securities: Municipal: Comprise municipal bonds that are not rated by third-party credit rating agencies. The primary inputs to the valuation of these municipal bonds include quoted prices for identical or similar assets that are not market observable, contractual cash flows, benchmark yields and credit spreads. Also included are municipal bonds valued based on non-binding broker quotes where the inputs have not been corroborated to be market observable and municipal bonds in default valued based on the present value of expected cash flows. Corporate - public and privately placed and ABS: Primarily valued based on non-binding broker quotes where the inputs have not been corroborated to be market observable. Other inputs for corporate fixed income securities include an interest rate yield curve, as well as published credit spreads for similar assets that incorporate the credit quality and industry sector of the issuer. • Equity securities: The primary inputs to the valuation include quoted prices or quoted net asset values for identical or similar assets that are not market observable. • Short-term: For certain short-term investments, amortized cost is used as the best estimate of fair value. • Other investments: Certain OTC derivatives, such as interest rate caps, certain credit default swaps and certain options (including swaptions), are valued using models that are widely accepted in the financial services industry. These are categorized as Level 3 as a result of the significance of non-market observable inputs such as volatility. Other primary inputs include interest rate yield curves and credit spreads, and quoted prices for identical or similar assets in markets that exhibit less liquidity relative to those markets supporting Level 2 fair value measurements. • Other assets: Includes the contingent consideration provision in the sale agreement for ALIC which meets the definition of a derivative. This derivative is valued internally using a model that includes stochastically determined cash flows and inputs that include spot and forward interest rates, volatility, corporate credit spreads and a liquidity discount. This derivative is categorized as Level 3 due to the significance of non-market observable inputs. Assets measured at fair value on a non-recurring basis Comprise long-lived assets to be disposed of by sale, including real estate, that are written down to fair value less costs to sell. Investments excluded from the fair value hierarchy Limited partnerships carried at fair value, which do not have readily determinable fair values, use NAV provided by the investees and are excluded from the fair value hierarchy. These investments are generally not redeemable by the investees and generally cannot be sold without approval of the general partner. The Company receives distributions of income and proceeds from the liquidation of the underlying assets of the investees, which usually takes place in years 4-9 of the typical contractual life of 10-12 years. As of March 31, 2023, the Company has commitments to invest $204 million in these limited partnership interests.

As the Company does not develop the Level 3 fair value unobservable inputs for these fixed income securities, they are not included in the table above. However, an increase (decrease) in credit spreads for fixed income securities valued based on non-binding broker quotes would result in a lower (higher) fair value, and an increase (decrease) in the credit rating of municipal bonds that are not rated by third-party credit rating agencies would result in a higher (lower) fair value.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Note 6 Derivative Financial Instruments The Company uses derivatives for risk reduction and to increase investment portfolio returns through asset replication. Risk reduction activity is focused on managing the risks with certain assets and liabilities arising from the potential adverse impacts from changes in risk-free interest rates, changes in equity market valuations, increases in credit spreads and foreign currency fluctuations. Asset replication refers to the “synthetic” creation of assets through the use of derivatives. The Company replicates fixed income securities using a combination of a credit default swap, index total return swap, options, futures, or a foreign currency forward contract and one or more highly rated fixed income securities, primarily investment grade host bonds, to synthetically replicate the economic characteristics of one or more cash market securities. The Company replicates equity securities using futures, index total return swaps, and options to increase equity exposure. Property-Liability may use interest rate swaps, swaptions, futures and options to manage the interest rate risks of existing investments. These instruments are utilized to change the duration of the portfolio in order to offset the economic effect that interest rates would otherwise have on the fair value of its fixed income securities. Fixed income index total return swaps are used to offset valuation losses in the fixed income portfolio during periods of declining market values. Credit default swaps are typically used to mitigate the credit risk within the Property-Liability fixed income portfolio. Equity index total return swaps, futures and options are used by Property-Liability to offset valuation losses in the equity portfolio during periods of declining equity market values. In addition, equity futures are used to hedge the market risk related to deferred compensation liability contracts. Forward contracts are primarily used by Property-Liability to hedge foreign currency risk associated with holding foreign currency denominated investments and foreign operations. In 2022, the Company also had derivatives embedded in non-derivative host contracts that were required to be separated from the host contracts and accounted for at fair value with changes in fair value of embedded derivatives reported in net income. When derivatives meet specific criteria, they may be designated as accounting hedges and accounted for as fair value, cash flow, foreign currency fair value or foreign currency cash flow hedges. The notional amounts specified in the contracts are used to calculate the exchange of contractual payments under the agreements and are generally not representative of the potential for gain or loss on these agreements. However, the notional amounts specified in credit default swaps where the Company has sold credit protection represent the maximum amount of potential loss, assuming no recoveries. Fair value, which is equal to the carrying value, is the estimated amount that the Company would receive or pay to terminate the derivative contracts at the reporting date. The carrying value amounts for OTC derivatives are further adjusted for the effects, if any, of enforceable master netting agreements and are presented on a net basis, by counterparty agreement, in the Condensed Consolidated Statements of Financial Position. For those derivatives which qualify and have been designated as fair value accounting hedges, net income includes the changes in the fair value of both the derivative instrument and the hedged risk. For cash flow hedges, gains and losses are amortized from AOCI and are reported in net income in the same period the forecasted transactions being hedged impact net income. Non-hedge accounting is generally used for “portfolio” level hedging strategies where the terms of the individual hedged items do not meet the strict homogeneity requirements to permit the application of hedge accounting. For non-hedge derivatives, net income includes changes in fair value and accrued periodic settlements, when applicable. With the exception of non-hedge derivatives used for asset replication and non-hedge embedded derivatives, all of the Company’s derivatives are evaluated for their ongoing effectiveness as either accounting hedge or non-hedge derivative financial instruments on at least a quarterly basis. In connection with the sale of ALIC and certain affiliates in 2021, the sale agreement included a provision related to contingent consideration that may be earned over a ten-year period with the first potential payment date commencing on January 1, 2026 and a final potential payment date of January 1, 2035. The contingent consideration is determined annually based on the average 10-year Treasury rate over the preceding 3-year period compared to a designated rate. The contingent consideration meets the definition of a derivative and is accounted for on a fair value basis with periodic changes in fair value reflected in earnings. There are no collateral requirements related to the contingent consideration.

The Company uses MNAs for OTC derivative transactions that permit either party to net payments due for transactions and collateral is either pledged or obtained when certain predetermined exposure limits are exceeded. OTC cash and securities collateral pledged ($ in millions) March 31, 2023 Pledged by the Company $ 19 Pledged to the Company (1) 3 (1) $1 million of collateral was posted under MNAs for contracts containing credit-risk-contingent provisions that are in a liability provision. The Company has not incurred any losses on derivative financial instruments due to counterparty nonperformance. Other derivatives, including futures and certain option contracts, are traded on organized exchanges which require margin deposits and guarantee the execution of trades, thereby mitigating any potential credit risk. Counterparty credit exposure represents the Company’s potential loss if all of the counterparties concurrently fail to perform under the contractual terms of the contracts and all collateral, if any, becomes worthless. This exposure is measured by the fair value of OTC derivative contracts with a positive fair value at the reporting date reduced by the effect, if any, of legally enforceable master netting agreements.

Market risk exists for all of the derivative financial instruments the Company currently holds, as these instruments may become less valuable due to adverse changes in market conditions. To limit this risk, the Company’s senior management has established risk control limits. In addition, changes in fair value of the derivative financial instruments that the Company uses for risk management purposes are generally offset by the change in the fair value or cash flows of the hedged risk component of the related assets, liabilities or forecasted transactions. Certain of the Company’s derivative transactions contain credit-risk-contingent termination events and cross-default provisions. Credit-risk-contingent termination events allow the counterparties to terminate the derivative agreement or a specific trade on certain dates if AIC’s financial strength credit ratings by Moody’s or S&P fall below a certain level. Credit-risk-contingent cross-default provisions allow the counterparties to terminate the derivative agreement if the Company defaults by pre-determined threshold amounts on certain debt instruments.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entities	Note 7 Variable Interest Entities Consolidated VIEs, of which the Company is the primary beneficiary, primarily include Adirondack Insurance Exchange, a New York reciprocal insurer, and New Jersey Skylands Insurance Association, a New Jersey reciprocal insurer (together “Reciprocal Exchanges”). The Reciprocal Exchanges are insurance carriers organized as unincorporated associations. The Company does not own the equity of the Reciprocal Exchanges, which is owned by their respective policyholders. The Company manages the business operations of the Reciprocal Exchanges and has the power to direct their activities that most significantly impact their economic performance. The Company receives a management fee for the services provided to the Reciprocal Exchanges. In addition, as of March 31, 2023 and December 31, 2022, the Company holds interests of $123 million in the form of surplus notes included in other liabilities and expenses on the Statement of Assets and Liabilities of the Reciprocal Exchanges that provide capital to the Reciprocal Exchanges and would absorb any expected losses. The Company is therefore the primary beneficiary. In addition, the Company provides quota share reinsurance on the property business of the Reciprocal Exchanges. In the event of dissolution, policyholders would share any residual unassigned surplus but are not subject to assessment for any deficit in unassigned surplus of the Reciprocal Exchanges. The assets of the Reciprocal Exchanges can be used only to settle the obligations of the Reciprocal Exchanges and general creditors have no recourse to the Company. The results of operations of the Reciprocal Exchanges are included in the Company’s Allstate Protection segment and generated $57 million of earned premiums for the three months ended March 31, 2023 compared to $42 million for the three months ended March 31, 2022. Claims and claims expenses were $40 million for the three months ended March 31, 2023 compared to $34 million for the three months ended March 31, 2022.

Reserve for Property-Liability Insurance Claims and Claims Expense [Abstract]
Reserve for Property and Liability Insurance Claims and Claims Expense	Note 8 Reserve for Property and Casualty Insurance Claims and Claims Expense The Company establishes reserves for claims and claims expense on reported and unreported claims of insured losses. The Company’s reserving process takes into account known facts and interpretations of circumstances and factors including the Company’s experience with similar cases, actual claims paid, historical trends involving claim payment patterns and pending levels of unpaid claims, loss management programs, product mix and contractual terms, changes in law and regulation, judicial decisions, and economic conditions. When the Company experiences changes in the mix or type of claims or changing claim settlement patterns or data, it applies actuarial judgment in the determination and selection of development factors to develop reserve liabilities. Supply chain disruptions and inflation have resulted in higher part costs, used car values and longer time to claim resolution, which have combined with labor shortages to increase physical damage loss costs. Medical inflation, treatment trends, attorney representation, litigation costs and more severe accidents have contributed to higher third-party bodily injury loss costs. The Company has also digitized and modified claim processes to increase effectiveness and efficiency. These factors may lead to historical development trends being less predictive of future loss development, potentially creating additional reserve variability. Generally, the initial reserves for a new accident year are established based on claim frequency and severity assumptions for different business segments, lines and coverages based on historical relationships to relevant inflation indicators. Reserves for prior accident years are statistically determined using several different actuarial estimation methods. Changes in auto claim frequency may result from changes in mix of business, driving behaviors, miles driven or other factors. Changes in auto current year claim severity are generally influenced by inflation in the medical and auto repair sectors, the effectiveness and efficiency of claim practices and changes in mix of claim types. The Company mitigates these effects through various loss management programs. When such changes in claim data occur, actuarial judgment is used to determine appropriate development factors to establish reserves. The Company’s reserving process incorporates changes in loss patterns, operational statistics and changes in claims reporting processes to determine its best estimate of recorded reserves. As part of the reserving process, the Company may also supplement its claims processes by utilizing third-party adjusters, appraisers, engineers, inspectors, and other professionals and information sources to assess and settle catastrophe and non-catastrophe related claims. The effects of inflation are implicitly considered in the reserving process. Because reserves are estimates of unpaid portions of losses that have occurred, including IBNR losses, the establishment of appropriate reserves, including reserves for catastrophes, Run-off Property-Liability and reinsurance and indemnification recoverables, is an inherently uncertain and complex process. The ultimate cost of losses may vary materially from recorded amounts, which are based on management’s best estimates. The highest degree of uncertainty is associated with reserves for losses incurred in the initial reporting period as it contains the greatest proportion of losses that have not been reported or settled as well as heightened uncertainty for claims that involve litigation or take longer to settle during periods of rapidly increasing loss costs. The Company also has uncertainty in the Run-off Property-Liability reserves that are based on events long since passed and are complicated by lack of historical data, legal interpretations, unresolved legal issues and legislative intent based on establishment of facts. The Company regularly updates its reserve estimates as new information becomes available and as events unfold that may affect the resolution of unsettled claims. Changes in reserve estimates, which may be material, are reported in property and casualty insurance claims and claims expense in the Condensed Consolidated Statements of Operations in the period such changes are determined. Management believes that the reserve for property and casualty insurance claims and claims expense, net of recoverables, is appropriately established in the aggregate and adequate to cover the ultimate net cost of reported and unreported claims arising from losses which had occurred by the date of the Condensed Consolidated Statements of Financial Position based on available facts, laws and regulations.

Company Restructuring	Note 13 Company Restructuring The Company undertakes various programs to reduce expenses. These programs generally involve a reduction in staffing levels, and in certain cases, office closures. Restructuring and related charges primarily include the following costs related to these programs: • Employee - severance and relocation benefits • Exit - contract termination penalties and real estate costs primarily related to accelerated amortization of right-of-use assets and related leasehold improvements at facilities to be vacated The expenses related to these activities are included in the Condensed Consolidated Statements of Operations as restructuring and related charges and totaled $27 million and $12 million during the three months ended March 31, 2023 and 2022, respectively. Restructuring expenses during the first quarter of 2023 are primarily due to real estate costs related to facilities being vacated.

Guarantees and Contingent Liabilities
Guarantees and Contingent Liabilities	Note 14 Guarantees and Contingent Liabilities Shared markets and state facility assessments The Company is required to participate in assigned risk plans, reinsurance facilities and joint underwriting associations in various states that provide insurance coverage to individuals or entities that otherwise are unable to purchase such coverage from private insurers. The Company routinely reviews its exposure to assessments from these plans, facilities and government programs. Underwriting results related to these arrangements, which tend to be adverse, have been immaterial to the Company’s results of operations in the last two years. Because of the Company’s participation, it may be exposed to losses that surpass the capitalization of these facilities or assessments from these facilities. Guarantees In the normal course of business, the Company provides standard indemnifications to contractual counterparties in connection with numerous transactions, including acquisitions and divestitures. The types of indemnifications typically provided include indemnifications for breaches of representations and warranties, taxes and certain other liabilities, such as third-party lawsuits. The indemnification clauses are often standard contractual terms and are entered into in the normal course of business based on an assessment that the risk of loss would be remote. The terms of the indemnifications vary in duration and nature. In many cases, the maximum obligation is not explicitly stated and the contingencies triggering the obligation to indemnify have not occurred and are not expected to occur. Consequently, the maximum amount of the obligation under such indemnifications is not determinable. Historically, the Company has not made any material payments pursuant to these obligations. Related to the sale of ALNY on October 1, 2021, AIC agreed to indemnify Wilton Reassurance Company in connection with certain representations, warranties and covenants of AIC, and certain liabilities specifically excluded from the transaction, subject to specific contractual limitations regarding AIC’s maximum obligation. Management does not believe these indemnifications will have a material effect on results of operations, cash flows or financial position of the Company. Related to the sale of ALIC and Allstate Assurance Company on November 1, 2021, AIC and Allstate Financial Insurance Holdings Corporation (collectively, the “Sellers”) agreed to indemnify Everlake US Holdings Company in connection with certain representations, warranties and covenants of the Sellers, and certain liabilities specifically excluded from the transaction, subject to specific contractual limitations regarding the Sellers’ maximum obligation. Management does not believe these indemnifications will have a material effect on results of operations, cash flows or financial position of the Company. The aggregate liability balance related to all guarantees was not material as of March 31, 2023. Regulation and compliance The Company is subject to extensive laws, regulations, administrative directives, and regulatory actions. From time to time, regulatory authorities or legislative bodies seek to influence and restrict premium rates, require premium refunds to policyholders, require reinstatement of terminated policies, prescribe rules or guidelines on how affiliates compete in the marketplace, restrict the ability of insurers to cancel or non-renew policies, require insurers to continue to write new policies or limit their ability to write new policies, limit insurers’ ability to change coverage terms or to impose underwriting standards, impose additional regulations regarding agency and broker compensation, regulate the nature of and amount of investments, impose fines and penalties for unintended errors or mistakes, impose additional regulations regarding cybersecurity and privacy, and otherwise expand overall regulation of insurance products and the insurance industry. In addition, the Company is subject to laws and regulations administered and enforced by federal agencies, international agencies, and other organizations, including but not limited to the Securities and Exchange Commission (“SEC”), the Financial Industry Regulatory Authority, the U.S. Equal Employment Opportunity Commission, and the U.S. Department of Justice. The Company has established procedures and policies to facilitate compliance with laws and regulations, to foster prudent business operations, and to support financial reporting. The Company routinely reviews its practices to validate compliance with laws and regulations and with internal procedures and policies. As a result of these reviews, from time to time the Company may decide to modify some of its procedures and policies. Such modifications, and the reviews that led to them, may be accompanied by payments being made and costs being incurred. The ultimate changes and eventual effects of these actions on the Company’s business, if any, are uncertain. Legal and regulatory proceedings and inquiries The Company and certain subsidiaries are involved in a number of lawsuits, regulatory inquiries, and other legal proceedings arising out of various aspects of its business. Background These matters raise difficult and complicated factual and legal issues and are subject to many uncertainties and complexities, including the underlying facts of each matter; novel legal issues; variations between jurisdictions in which matters are being litigated, heard, or investigated; changes in assigned judges; differences or developments in applicable laws and judicial interpretations; judges reconsidering prior rulings; the length of time before many of these matters might be resolved by settlement, through litigation, or otherwise; adjustments with respect to anticipated trial schedules and other proceedings; developments in similar actions against other companies; the fact that some of the lawsuits are putative class actions in which a class has not been certified and in which the purported class may not be clearly defined; the fact that some of the lawsuits involve multi-state class actions in which the applicable law(s) for the claims at issue is in dispute and therefore unclear; and the challenging legal environment faced by corporations and insurance companies. The outcome of these matters may be affected by decisions, verdicts, and settlements, and the timing of such decisions, verdicts, and settlements, in other individual and class action lawsuits that involve the Company, other insurers, or other entities and by other legal, governmental, and regulatory actions that involve the Company, other insurers, or other entities. The outcome may also be affected by future state or federal legislation, the timing or substance of which cannot be predicted. In the lawsuits, plaintiffs seek a variety of remedies which may include equitable relief in the form of injunctive and other remedies and monetary relief in the form of contractual and extra-contractual damages. In some cases, the monetary damages sought may include punitive or treble damages. Often specific information about the relief sought, such as the amount of damages, is not available because plaintiffs have not requested specific relief in their pleadings. When specific monetary demands are made, they are often set just below a state court jurisdictional limit in order to seek the maximum amount available in state court, regardless of the specifics of the case, while still avoiding the risk of removal to federal court. In Allstate’s experience, monetary demands in pleadings bear little relation to the ultimate loss, if any, to the Company. In connection with regulatory examinations and proceedings, government authorities may seek various forms of relief, including penalties, restitution, and changes in business practices. The Company may not be advised of the nature and extent of relief sought until the final stages of the examination or proceeding. Accrual and disclosure policy The Company reviews its lawsuits, regulatory inquiries, and other legal proceedings on an ongoing basis and follows appropriate accounting guidance when making accrual and disclosure decisions. The Company establishes accruals for such matters at management’s best estimate when the Company assesses that it is probable that a loss has been incurred and the amount of the loss can be reasonably estimated. The Company does not establish accruals for such matters when the Company does not believe both that it is probable that a loss has been incurred and the amount of the loss can be reasonably estimated. The Company’s assessment of whether a loss is reasonably possible or probable is based on its assessment of the ultimate outcome of the matter following all appeals. The Company does not include potential recoveries in its estimates of reasonably possible or probable losses. Legal fees are expensed as incurred. The Company continues to monitor its lawsuits, regulatory inquiries, and other legal proceedings for further developments that would make the loss contingency both probable and estimable, and accordingly accruable, or that could affect the amount of accruals that have been previously established. There may continue to be exposure to loss in excess of any amount accrued. Disclosure of the nature and amount of an accrual is made when there have been sufficient legal and factual developments such that the Company’s ability to resolve the matter would not be impaired by the disclosure of the amount of accrual. When the Company assesses it is reasonably possible or probable that a loss has been incurred, it discloses the matter. When it is possible to estimate the reasonably possible loss or range of loss above the amount accrued, if any, for the matters disclosed, that estimate is aggregated and disclosed. Disclosure is not required when an estimate of the reasonably possible loss or range of loss cannot be made. For certain of the matters described below in the “Claims related proceedings” and “Other proceedings” subsections, the Company is able to estimate the reasonably possible loss or range of loss above the amount accrued, if any. In determining whether it is possible to estimate the reasonably possible loss or range of loss, the Company reviews and evaluates the disclosed matters, in conjunction with counsel, in light of potentially relevant factual and legal developments. These developments may include information learned through the discovery process, rulings on dispositive motions, settlement discussions, information obtained from other sources, experience from managing these and other matters, and other rulings by courts, arbitrators or others. When the Company possesses sufficient appropriate information to develop an estimate of the reasonably possible loss or range of loss above the amount accrued, if any, that estimate is aggregated and disclosed below. There may be other disclosed matters for which a loss is probable or reasonably possible, but such an estimate is not possible. Disclosure of the estimate of the reasonably possible loss or range of loss above the amount accrued, if any, for any individual matter would only be considered when there have been sufficient legal and factual developments such that the Company’s ability to resolve the matter would not be impaired by the disclosure of the individual estimate. The Company currently estimates that the aggregate range of reasonably possible loss in excess of the amount accrued, if any, for the disclosed matters where such an estimate is possible is zero to $148 million, pre-tax. This disclosure is not an indication of expected loss, if any. Under accounting guidance, an event is “reasonably possible” if “the chance of the future event or events occurring is more than remote but less than likely” and an event is “remote” if “the chance of the future event or events occurring is slight.” This estimate is based upon currently available information and is subject to significant judgment and a variety of assumptions and known and unknown uncertainties. The matters underlying the estimate will change from time to time, and actual results may vary significantly from the current estimate. The estimate does not include matters or losses for which an estimate is not possible. Therefore, this estimate represents an estimate of possible loss only for certain matters meeting these criteria. It does not represent the Company’s maximum possible loss exposure. Information is provided below regarding the nature of all of the disclosed matters and, where specified, the amount, if any, of plaintiff claims associated with these loss contingencies. Due to the complexity and scope of the matters disclosed in the “Claims related proceedings” and “Other proceedings” subsections below and the many uncertainties that exist, the ultimate outcome of these matters cannot be predicted and in the Company’s judgment, a loss, in excess of amounts accrued, if any, is not probable. In the event of an unfavorable outcome in one or more of these matters, the ultimate liability may be in excess of amounts currently accrued, if any, and may be material to the Company’s operating results or cash flows for a particular quarterly or annual period. However, based on information currently known to it, management believes that the ultimate outcome of all matters described below, as they are resolved over time, is not likely to have a material effect on the financial position of the Company. Claims related proceedings The Company is managing various disputes in Florida that raise challenges to the Company’s practices, processes, and procedures relating to claims for personal injury protection benefits under Florida auto policies. Medical providers continue to pursue litigation under various theories that challenge the amounts that the Company pays under the personal injury protection coverage, seeking additional benefit payments, as well as applicable interest, penalties and fees. There is a pending lawsuit, Revival Chiropractic v. Allstate Insurance Company, et al. (M.D. Fla. filed January 2019; appeal pending, 11 th Circuit Court of Appeals), where the federal district court denied class certification and plaintiff’s request to file a renewed motion for class certification. In Revival , on June 2, 2022, the 11 th Circuit certified to the Florida Supreme Court Allstate’s appeal of the federal district court’s interpretation of the state personal injury protection statute. The 11 th Circuit is holding determination on plaintiff’s class certification appeal pending the outcome of the Florida Supreme Court certification. The oral argument before the Florida Supreme Court was on March 8, 2023. The Company is also defending litigation involving individual plaintiffs. The Company is defending putative class actions in various courts that raise challenges to the Company’s depreciation practices in homeowner property claims. In these lawsuits, plaintiffs generally allege that, when calculating actual cash value, the costs of “non-materials” such as labor, general contractor’s overhead and profit, and sales tax should not be subject to depreciation. The Company is currently defending the following lawsuits on this issue: Clark v. Allstate Vehicle and Property Insurance Company (Circuit Court of Independence Co., Ark. filed February 2016); Sims, et al. v. Allstate Fire and Casualty Insurance Company, et al. (W.D. Tex. filed June 2022); Thompson, et al. v. Allstate Insurance Company (Circuit Court of Cole Co., Mo. filed June 2022); Hill v. Allstate Vehicle and Property Insurance Compan y (Circuit Court of Cole Co., Mo. filed October 2022); Tabuga v. Allstate Vehicle and Property Insurance Company (D. Md. filed April 2023); and Shumway, et al. v Allstate Vehicle and Property Insurance Company (D. Ariz. filed April 2023). No classes have been certified in any of these matters. The court granted preliminary approval of a class-wide settlement in the following cases: Perry v. Allstate Indemnity Company, et al . (N.D. Ohio filed May 2016); Lado v. Allstate Vehicle and Property Insurance Company (S.D. Ohio filed March 2020); Maniaci v. Allstate Insurance Company (N.D. Ohio filed March 2020); Ferguson-Luke, et al. v. Allstate Property and Casualty Insurance Company (N.D. Ohio filed April 2020); Mitchell, et al. v. Allstate Vehicle and Property Insurance Company, et al . (S.D. Ala. filed August 2021); and Hester, et al. v. Allstate Vehicle and Property Insurance Company, et al . (St. Clair Co., Ill. filed June 2020) (as part of the proposed class-wide settlement, the plaintiff and defendant in Thaxton v. Allstate Indemnity Company (Madison Co., Ill. filed July 2020) were added to the Hester complaint). The Company is defending putative class actions pending in multiple states alleging that the Company underpays total loss vehicle physical damage claims on auto policies. The alleged systematic underpayments result from one or more of the following theories: (a) the third party valuation tool used by the Company as part of a comprehensive adjustment process is allegedly flawed, biased, or contrary to applicable law; or (b) the Company allegedly does not pay sales tax, title fees, registration fees, and/or other specified fees that are allegedly mandatory under policy language or state legal authority. The following cases are currently pending against the Company: Kronenberg v. Allstate Insurance Company and Allstate Fire and Casualty Insurance Company (E.D.N.Y. filed December 2018); Durgin v. Allstate Property and Casualty Insurance Company (W.D. La. filed June 2019); Cotton v. Allstate Fire and Casualty Insurance Company (Cir. Ct. of Cook Co. Ill., Chancery Div. filed October 2020); Bass v. Imperial Fire and Casualty Insurance Company (W.D. La. filed February 2022); Cummings v. Allstate Property and Casualty Insurance Company (M.D. La. filed April 2022); Slaughter v. Esurance Property and Casualty Insurance Company (Cir. Ct. of Cook Co, Ill., Chancery Div. filed September 2022); and Kanak v. Allstate Fire and Casualty Insurance Company (Cir. Ct. of Cook Co., Ill., Chancery Div. filed September 2022). None of the courts in any of the pending matters has ruled on class certification. Other proceedings The Company is defending against an investigatory hearing before the California Insurance Commissioner concerning the private passenger automobile insurance rating practices of Allstate Insurance Company and Allstate Indemnity Company in California. The investigatory hearing is captioned: In the Matter of the Rating Practices of Allstate Insurance Company and Allstate Indemnity Company. Pursuant to the Notice of Hearing issued by the California Insurance Commissioner, the California Insurance Commissioner is investigating: (1) whether Allstate has potentially violated California insurance law by using illegal price optimization; (2) how Allstate implemented any such potentially illegal price optimization in its private passenger auto insurance rates and/or class plans; and (3) how such potentially illegal price optimization impacted Allstate’s private passenger auto insurance policyholders. Fact discovery has been completed in the investigatory hearing. The hearing is scheduled for May 22, 2023. In re The Allstate Corp. Securities Litigation is a certified class action filed on November 11, 2016 in the United States District Court for the Northern District of Illinois against the Company and two of its officers asserting claims under the federal securities laws. Plaintiffs allege that they purchased Allstate common stock during the class period and suffered damages as the result of the conduct alleged. Plaintiffs seek an unspecified amount of damages, costs, attorney’s fees, and other relief as the court deems appropriate. Plaintiffs allege that the Company and certain senior officers made allegedly material misstatements or omissions concerning claim frequency statistics and the reasons for a claim frequency increase for Allstate brand auto insurance between October 2014 and August 3, 2015. Plaintiffs further allege that a senior officer engaged in stock option exercises during that time allegedly while in possession of material nonpublic information about Allstate brand auto insurance claim frequency. The Company, its chairman, president and chief executive officer, and its former president are the named defendants. After the court denied their motion to dismiss on February 27, 2018, defendants answered the complaint, denying plaintiffs’ allegations that there was any misstatement or omission or other misconduct. On June 22, 2018, plaintiffs filed their motion for class certification. The court allowed the lead plaintiffs to amend their complaint to add the City of Providence Employee Retirement System as a proposed class representative and on September 12, 2018, the amended complaint was filed. A class was certified on March 26, 2019, vacated by the U.S. Court of Appeals for the Seventh Circuit on July 16, 2020 and remanded for further consideration by the district court. On December 21, 2020, the district court again granted plaintiffs’ motion for class certification and certified a class consisting of all persons who purchased Allstate common stock between October 29, 2014 and August 3, 2015. Defendants’ petition for permission to appeal this ruling was denied on January 28, 2021. Following the close of discovery, defendants moved for summary judgment on March 23, 2022. On July 26, 2022, the court entered its order granting summary judgment in part (as to plaintiffs’ claims relating to certain statements made in October 2014) and denying it as to the remainder of plaintiffs’ claims. On January 10, 2023, the parties filed a joint pre-trial order. There is no date currently set for a pre-trial conference. The Company is continuing to defend two putative class actions in California federal court, Holland Hewitt v. Allstate Life Insurance Company (E.D. Cal. filed May 2020) and Farley v. Lincoln Benefit Life Compan y (E.D. Cal. filed Dec. 2020), following the sale of ALIC. On April 19, 2023, the court certified a class in Farley. There has been no ruling on plaintiff’s motion for class certification in Hewitt. In these cases, plaintiffs generally allege that the defendants failed to comply with certain California statutes which address contractual grace periods and lapse notice requirements for certain life insurance policies. Plaintiffs claim that these statutes apply to life insurance policies that existed before the statutes’ effective date. The plaintiffs seek damages and injunctive relief. Similar litigation is pending against other insurance carriers. In August 2021, the California Supreme Court in McHugh v. Protective Life , a matter involving another insurer, determined that the statutory notice requirements apply to life insurance policies issued before the statutes’ effective date. The Company asserts various defenses to plaintiffs’ claims and to class certification.

Basis of presentation	Basis of presentation The accompanying condensed consolidated financial statements include the accounts of The Allstate Corporation (the “Corporation”) and its wholly owned subsidiaries, primarily Allstate Insurance Company (“AIC”), a property and casualty insurance company (collectively referred to as the “Company” or “Allstate”) and variable interest entities (“VIEs”) in which the Company is considered a primary beneficiary. These condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The condensed consolidated financial statements and notes as of March 31, 2023 and for the three month periods ended March 31, 2023 and 2022 are unaudited. The condensed consolidated financial statements reflect all adjustments (consisting only of normal recurring accruals) which are, in the opinion of management, necessary for the fair presentation of the financial position, results of operations and cash flows for the interim periods. 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 annual report on Form 10-K for the year ended December 31, 2022. The results of operations for the interim periods should not be considered indicative of results to be expected for the full year. All significant intercompany accounts and transactions have been eliminated. To reflect the application of the new guidance to all in-scope long-duration insurance contracts, certain amounts in the condensed consolidated financial statements and notes for 2022 have been recast.
Accounting standard	Adopted accounting standard Accounting for Long-Duration Insurance Contracts Effective January 1, 2023, the Company adopted the Financial Accounting Standards Board (”FASB”) guidance revising the accounting for certain long-duration insurance contracts using the modified retrospective approach to the transition date of January 1, 2021. Under the new guidance, measurement assumptions, including those for mortality, morbidity and policy lapses, are required to be reviewed at least annually, and updated as appropriate. In addition, reserves under the new guidance are required to be discounted using an upper-medium grade fixed income instrument yield that is updated through other comprehensive income (“OCI”) at each reporting date. Additionally, deferred policy acquisition costs (“DAC”) for all long-duration products will be amortized on a simplified basis. Also, the Company’s reserve for future policy benefits and DAC will be subject to new disclosure guidance. In addition, the Company met the conditions included in Accounting Standards Update No. 2022-05, Transition for Sold Contracts , and elected to not apply the new guidance for contracts that were part of the 2021 sales of Allstate Life Insurance Company (“ALIC”) and Allstate Life Insurance Company of New York (“ALNY”). After-tax cumulative effect of change in accounting principle on transition date ($ in millions) January 1, 2021 Decrease in retained income $ 21 Decrease in accumulated other comprehensive income (“AOCI”) 277 Total decrease in equity $ 298 The decrease in AOCI is primarily attributable to a change in the discount rate used in measuring the reserve for future policy benefits for traditional life contracts and other long-term products with guaranteed terms from a portfolio-based rate at contract issuance to an upper-medium grade fixed income-based rate at the reporting date. The decrease in retained income primarily relates to certain cohorts of long-term contracts whose expected net premiums exceeded expected gross premiums which resulted in an increase in reserves and a decrease in retained income equal to the present value of expected future benefits less the present value of expected future premiums at the transition date. Changes to significant accounting policies Reserve for future policy benefits Long-duration voluntary accident and health insurance and traditional life insurance contracts The reserve for future policy benefits (“RFPB”) is calculated using the net premium reserving model, which uses the present value of insurance contract benefits less the present value of net premiums. Under the net premium reserving model, the Company computes a net premium ratio which is the present value of insurance contract benefits divided by the present value of gross premiums. The present value of contract benefits and gross premiums are determined using the discount rate at contract inception. The net premium ratio is applied to premiums due on a periodic basis to compute the RFPB. The net premium ratio is recomputed at least annually using both actual historical cash flows and future cash flows anticipated over the life of cohort of contracts subject to measurement. Assumptions including mortality, morbidity, and lapses affect the timing and amount of estimated cash flows used to calculate the RFPB. The Company has grouped contracts into cohorts based on product type and issue year. Examples of insurance product types include whole life, term life, critical illness and disability. Issue year is based on the issuance date of the contract to the policyholder, except in the case of contracts acquired in a business combination, where the issue date is based on the acquisition date of the business combination. The RFPB is calculated for contracts in force at the end of each period, which results in the Company recognizing the effects of actual experience in the period it occurs. Annually, in the third quarter, the Company obtains historical premiums and benefits information and evaluates future cash flow assumptions that include mortality, morbidity, and terminations, and updates cash flow assumptions as necessary. The Company has elected to not update the expense assumption when annually reviewing and updating future cash flow assumptions. Actual premiums and benefits and any updates to future cash flow assumptions are incorporated into the calculation of an updated net premium ratio. Updates for actual premiums and benefits and changes to future cash flow assumptions will result in a liability remeasurement gain or loss that is recognized in net income. The first step to determining the liability remeasurement gain or loss is to calculate the RFPB using revised net premiums discounted at the locked-in discount rate set at contract issuance. The result of the first step is then compared to the carrying amount of the RFPB before the updates for actual experience and changes to future cash flow assumptions. The decrease (gain) or increase (loss) in the RFPB is reported as liability remeasurement gain or loss in net income and presented parenthetically as part of Accident, health and other policy benefits on the Consolidated Statements of Operations. The updated net premium ratio is used in future quarters to measure the RFPB until the next annual update or an earlier date if the Company determines it is necessary to revise future cash flow assumptions based on available evidence, including actual experience . The discount rate assumption is determined using a yield curve approach. The yield curve consists of U.S. dollar-denominated senior unsecured fixed-income securities issued by U.S. companies that have an A credit rating based on the ratings provided by nationally recognized rating agencies that include Moody’s, Standard & Poor’s, and Fitch. For points on the yield curve that do not have observable yields, the Company uses linear interpolation w hich calculates the unobservable yield based on the two nearest observable yields, except for any points beyond the last observable yield at 30 years, where interest rates are held constant with the last observable point on the yield curve. The Company updates the current discount rate quarterly and the change in the RFPB resulting from the updated current discount rate is recognized in OCI.
Deferred policy acquisition costs	Deferred policy acquisition costs Deferred policy acquisition costs are related directly to the successful acquisition of new or renewal insurance contracts and are deferred and recognized as an expense over the life of the related contracts. These costs are principally agent and broker remuneration, premium taxes and certain underwriting expenses. All other acquisition costs are expensed as incurred and included in operating costs and expenses . Long-duration voluntary accident and health insurance, traditional life insurance contracts, and interest-sensitive life insurance contracts Voluntary accident and health insurance and traditional life insurance contracts are grouped by product and issue year into cohorts consistent with the cohorts used to calculate the RFPB. Interest-sensitive life insurance contracts are grouped into cohorts by issue year, and the issue year is determined based on contract issue date. DAC is amortized on a constant level basis over the expected contract term and is included in Amortization of deferred policy acquisition costs on the Consolidated Statements of Operations. The constant level basis used for all cohorts is based on policies-in-force. The expected contract term and mortality, morbidity, and termination assumptions are used to calculate both DAC amortization and the RFPB. If actual contract terminations are greater than expected terminations for any cohort, each affected cohort’s DAC balance will be reduced in the current period based on the difference between the actual and expected terminations. No adjustments to DAC amortization are recorded if actual contract terminations are less than expected terminations for any cohort. If the Company makes an update to any of its mortality, morbidity, or termination assumptions, the Company will use the assumptions prospectively to amortize any cohort’s remaining DAC over the remaining expected contract term. The costs assigned to the right to receive future cash flows from certain business purchased from other insurers are also classified as DAC in the Consolidated Statements of Financial Position. The costs capitalized represent the present value of future profits expected to be earned over the lives of the contracts acquired. The Company amortizes the present value of future profits using the same methodology and assumptions as the amortization of DAC. The present value of future profits is subject to premium deficiency testing.
Earnings per common share	Basic earnings per common share is computed using the weighted average number of common shares outstanding, including vested unissued participating restricted stock units. Diluted earnings per common share is computed using the weighted average number of common and dilutive potential common shares outstanding. For the Company, dilutive potential common shares consist of outstanding stock options, unvested non-participating restricted stock units and contingently issuable performance stock awards. The effect of dilutive potential common shares does not include the effect of options with an anti-dilutive effect on earnings per common share because their exercise prices exceed the average market price of Allstate common shares during the period or for which the unrecognized compensation cost would have an anti-dilutive effect.
