Notes to Condensed Consolidated Financial Statements

(Unaudited)

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 with various property and casualty and life and investment subsidiaries, including Allstate Life Insurance Company (“ALIC”) (collectively referred to as the “Company” or “Allstate”). 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, 2018 and for the three month periods ended March 31, 2018 and 2017 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, 2017. 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.

Adopted accounting standards

Recognition and Measurement of Financial Assets and Financial Liabilities

Effective January 1, 2018, the Company adopted new Financial Accounting Standards Board (“FASB”) guidance requiring equity investments, including equity securities and limited partnership interests not accounted for under the equity method of accounting or that do not result in consolidation to be measured at fair value with changes in fair value recognized in net income. The guidance clarifies that an entity should evaluate the realizability of deferred tax assets related to available-for-sale fixed income securities in combination with the entity’s other deferred tax assets. The Company’s adoption of the new FASB guidance included adoption of the relevant elements of Technical Corrections and Improvements to Financial Instruments, issued in February 2018.

Upon adoption of the new guidance on January 1, 2018, $1.16 billion of pre-tax unrealized net capital gains for equity securities were reclassified from AOCI to retained income. The after-tax change in accounting for equity securities did not affect the Company’s total shareholders’ equity and the unrealized net capital

gains reclassified to retained income will never be recognized in net income.

Upon adoption of the new guidance on January 1, 2018, the carrying value of cost method limited partnership interests increased $224 million, pre-tax to fair value. The after-tax cumulative-effect increase in retained income of $177 million increased the Company’s shareholders’ equity but will never be recognized in net income thereby negatively impacting calculations of returns on equity.

Revenue from Contracts with Customers

Effective January 1, 2018, the Company adopted new FASB guidance which revises the criteria for revenue recognition. Insurance contracts are excluded from the scope of the new guidance. The Company’s principal activities impacted by the new guidance are those related to the issuance of protection plans for consumer products and automobiles and service contracts that provide roadside assistance. Under the guidance, the transaction price is attributed to underlying performance obligations in the contract and revenue is recognized as the entity satisfies performance obligations and transfers control of a good or service to the customer. Incremental costs of obtaining a contract may be capitalized to the extent the entity expects to recover those costs.

Adoption of the guidance on January 1, 2018 under the modified retrospective approach resulted in the recognition of an immaterial after-tax net cumulative effect increase to the beginning balance of retained income. In addition to the net cumulative effect, the Company also recorded in the statement of financial position an increase of approximately $160 million pre-tax in unearned premiums with a corresponding $160 million pre-tax increase in DAC for protection plans sold directly to retailers for which SquareTrade is deemed to be the principal in the transaction. These impacts offset fully and did not impact retained income at the date of adoption.

Presentation of Net Periodic Pension and Postretirement Benefits Costs

Effective January 1, 2018, the Company adopted new FASB guidance requiring identification, on the statement of operations or in disclosures, the line items in which the components of net periodic pension and postretirement benefits costs are presented. The new guidance permits only the service cost component to be eligible for capitalization where applicable. The adoption had no impact on the Company’s results of operations or financial position.

Goodwill Impairment

In January 2017, the FASB issued guidance to simplify the accounting for goodwill impairment which removes the second step of the goodwill impairment

6www.allstate.com

Notes to Condensed Consolidated Financial Statements

test that requires a hypothetical purchase price allocation. Under the new guidance, goodwill impairment will be measured and recognized as the amount by which a reporting unit’s carrying value, including goodwill, exceeds its fair value, not to exceed the carrying amount of goodwill allocated to the reporting unit. The revised guidance does not affect a reporting entity’s ability to first assess qualitative factors by reporting unit to determine whether to perform the quantitative goodwill impairment test. The guidance is to be applied on a prospective basis, with the effects, if any, recognized in net income in the period of adoption. The Company elected to early adopt the new guidance as of January 1, 2018. The adoption had no impact on the Company’s results of operations or financial position.

Changes to significant accounting policies

Investments

Changes were made to the Company’s Significant Accounting Policies upon adoption of new FASB guidance related to the recognition and measurement of financial assets. Equity securities primarily include common stocks, exchange traded and mutual funds, non-redeemable preferred stocks and real estate investment trust equity investments. Equity securities are carried at fair value. Equity securities without readily determinable or estimable fair values are measured using the measurement alternative which is cost less impairment, if any, and adjustments resulting from observable price changes in orderly transactions for the identical or similar investment of the same issuer. The periodic change in fair value of equity securities is recognized within realized capital gains and losses on the Condensed Consolidated Statements of Operations effective January 1, 2018.

Investments in limited partnership interests include interests in private equity funds, real estate funds and other funds. Where the Company’s interest is so minor that it exercises virtually no influence over operating and financial policies, investments in limited partnership interests purchased prior to January 1, 2018 are accounted for at fair value primarily utilizing the net asset value as a practical expedient (“NAV”) to determine fair value. All other investments in limited partnership interests, including those purchased subsequent to January 1, 2018, are accounted for in accordance with the equity method of accounting (“EMA”).

Investment income from limited partnership interests carried at fair value is recognized based upon the changes in fair value of the investee’s equity primarily determined using NAV. Income from EMA limited partnership interests is recognized based on the Company’s share of the partnerships’ earnings. Income from EMA limited partnership interests is generally recognized on a three month delay due to the availability of the related financial statements.

Recognition of Revenue

Revenues related to protection plans, other contracts (primarily finance and insurance products) and roadside assistance are deferred and earned over

the term of the contract in a manner that recognizes revenue as obligations under the contracts are performed. Revenues from these products are classified as premiums as the products are backed by insurance. Protection plans and finance and insurance premiums are recognized using a cost-based incurrence method. Roadside assistance premiums are recognized evenly over the term of the contract as performance obligations are fulfilled.

Tax Reform

On December 22, 2017, Public Law 115-97, known as the Tax Cuts and Jobs Act of 2017 (“Tax Legislation”) became effective, permanently reducing the U.S. corporate income tax rate from 35% to 21% beginning January 1, 2018. As a result, the corporate tax rate is not comparable between periods.

Pending accounting standards

Accounting for Leases

In February 2016, the FASB issued guidance revising the accounting for leases. Under the new guidance, lessees will be required to recognize a right-of-use asset and lease liability for all leases other than those that meet the definition of a short-term lease. The lease liability will be equal to the present value of lease payments. A right-of-use asset will be based on the lease liability adjusted for qualifying initial direct costs. Recognition of the lease liability and right-of-use asset will result in an increase in total assets and liabilities in the Condensed Consolidated Statement of Financial Position. The expense of operating leases under the new guidance will be recognized in the income statement on a straight-line basis by adjusting the amortization of the right-of-use asset to produce a straight-line expense when combined with the interest expense on the lease liability. For finance leases, the expense components are computed separately and produce greater up-front expense compared to operating leases as interest expense on the lease liability is higher in early years and the right-of-use asset is amortized on a straight-line basis. Lease classification will be based on criteria similar to those currently applied. The accounting model for lessors will be similar to the current model with modifications to reflect definition changes for components such as initial direct costs. Lessors will continue to classify leases as operating, direct financing, or sales-type. The guidance is effective for reporting periods beginning after December 15, 2018, using a modified retrospective approach applied at the beginning of the earliest period presented. The FASB has exposed for comment an optional simplified transition approach that would allow application of the transition provisions at the effective date instead of the earliest date presented. The Company is in the process of evaluating the impact of adoption, which is not expected to be material to the Company’s results of operations or financial position.

Measurement of Credit Losses on Financial Instruments

In June 2016, the FASB issued guidance which revises the credit loss recognition criteria for certain

First Quarter 2018 Form 10-Q 7

Notes to Condensed Consolidated Financial Statements

financial assets measured at amortized cost, including reinsurance recoverables. The new guidance replaces the existing incurred loss recognition model with an expected loss recognition model. The objective of the expected credit loss model is for the reporting entity to recognize its estimate of expected credit losses for affected financial assets in a valuation allowance deducted from the amortized cost basis of the related financial assets that results in presenting the net carrying value of the financial assets at the amount expected to be collected. The reporting entity must consider all relevant information available when estimating expected credit losses, including details about past events, current conditions, and reasonable and supportable forecasts over the life of an asset. Financial assets may be evaluated individually or on a pooled basis when they share similar risk characteristics. The measurement of credit losses for available-for-sale debt securities measured at fair value is not affected except that credit losses recognized are limited to the amount by which fair value is below amortized cost and the carrying value adjustment is recognized through a valuation allowance and not as a direct write-down. The guidance is effective for reporting periods beginning after December 15, 2019, and for most affected instruments must be adopted using a modified retrospective approach, with a cumulative effect adjustment recorded to beginning retained income. The Company is in the process of evaluating the impact of adoption.

Accounting for Hedging Activities

In August 2017, the FASB issued amendments intended to better align hedge accounting with an organization’s risk management activities. The

amendments expand hedge accounting for nonfinancial and financial risk components and revise the measurement methodologies to better align with an organization’s risk management activities. Separate presentation of hedge ineffectiveness is eliminated to provide greater transparency of the full impact of hedging by requiring presentation of the results of the hedged item and hedging instrument in a single financial statement line item. In addition, the amendments reduce complexity by simplifying the manner in which assessments of hedge effectiveness may be performed. The guidance is effective for reporting periods beginning after December 15, 2018. The presentation and disclosure guidance is effective on a prospective basis. The impact of adoption is not expected to be material to the Company’s results of operations or financial position.

Other revenue presentation

Concurrent with the adoption of new FASB guidance on revenue from contracts with customers and the Company’s objective of providing more information related to revenues for our Services Businesses, the Company revised the presentation of total revenue to include other revenue. Previously, components of other revenue were presented within operating costs and expenses and primarily represent fees collected from policyholders relating to premium installment payments, commissions on sales of non-proprietary products, fee-based services and other revenue transactions. Other revenue is recognized when performance obligations are fulfilled. Prior periods have been reclassified to conform to current separate presentation of other revenue.

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 and 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.

Options to purchase 1.0 million and 2.8 million Allstate common shares, with exercise prices ranging from $86.61 to $102.84 and $67.81 to $81.86, were outstanding for the three-month periods ended March 31, 2018 and 2017, respectively, but were not included in the computation of diluted earnings per common share in those periods.

Note 3 Acquisition

On January 3, 2017, the Company acquired SquareTrade Holding Company, Inc. (“SquareTrade”), a consumer product protection plan provider that distributes through many of America’s major retailers and Europe’s mobile operators, for $1.4 billion in cash. SquareTrade is a provider of consumer electronics and appliance protection plans covering products including TVs, smartphones and computers. This acquisition broadens Allstate’s unique product offerings to better meet consumers’ needs.

In connection with the acquisition, the Company recorded goodwill of $1.10 billion, commissions paid to retailers (reported in deferred policy acquisition costs) of $66 million, other intangible assets (reported in other assets) of $555 million, contractual liability

insurance policy premium expenses (reported in other assets) of $205 million, unearned premiums of $389 million and net deferred income tax liability of $138 million. These amounts reflect re-measurement adjustments to the fair value of the opening balance sheet assets and liabilities.

Of the $555 million assigned to other intangible assets, $465 million is attributable to acquired customer relationships. The $555 million assigned to other intangible assets also included $69 million assigned to the SquareTrade trade name which is considered to have an indefinite useful life. The amortization expense of intangible assets for the three months ended March 31, 2018 and 2017 was $21 million and $23 million, respectively.

The Company uses its best estimate of future cash flows expected to be collected from the fixed income security, discounted at the security’s original or current effective rate, as appropriate, to calculate a recovery value and determine whether a credit loss exists. 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, including past events, current conditions, and reasonable and supportable assumptions and forecasts, are 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, foreign exchange rates, the financial condition and future earnings potential of the issue or issuer, expected defaults, expected recoveries, the value of underlying collateral, vintage, 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, sector 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 estimated recovery value is less than the amortized cost of the security, a credit loss exists and an OTTI for the difference between the estimated recovery value and amortized cost is recorded in earnings. 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.

First Quarter 2018 Form 10-Q 15

Portfolio monitoring

The Company has a comprehensive portfolio monitoring process to identify and evaluate each fixed income security whose carrying value may be other-than-temporarily impaired.

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, the security’s decline in fair value is considered other than temporary and is 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 by discounting the best estimate of future cash flows at the security’s original or current effective rate, as appropriate, and compares this to the amortized cost of the security. If the Company does not expect to receive cash flows sufficient to recover the entire amortized cost basis of the fixed income security, the credit loss component of the impairment is recorded in earnings, with the remaining amount of the unrealized loss related to other factors recognized in other comprehensive income.

For fixed income securities managed by third parties, either the Company has contractually retained its decision-making authority as it pertains to selling securities that are in an unrealized loss position or it recognizes any unrealized loss at the end of the period through a charge to earnings.

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 established thresholds. The process also includes the monitoring of other impairment 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 OTTI using all reasonably available information relevant to the collectability or recovery of the security. Inherent in the Company’s evaluation of OTTI 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 is other than temporary 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 length of time and extent to which the fair value has been less than amortized cost.

As of March 31, 2018, $721 million of the $745 million unrealized losses are related to securities with an unrealized loss position less than 20% of amortized cost, the degree of which suggests that these securities do not pose a high risk of being other-than-temporarily impaired. Of the $721 million, $611 million are related to unrealized losses on investment grade fixed income securities. Of the remaining $110 million, $92 million have been in an unrealized loss position for less than 12 months. Investment grade is defined as a security having a rating of Aaa, Aa, A or Baa from Moody’s, a rating of AAA, AA, A or BBB from S&P Global Ratings (“S&P”), a comparable rating from another nationally recognized rating agency, 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 and/or wider credit spreads since the time of initial purchase.

As of March 31, 2018, the remaining $24 million of unrealized losses are related to securities in unrealized loss positions greater than or equal to 20% of amortized cost. Investment grade fixed income

securities comprising $12 million of these unrealized losses were 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. Of the $24 million, $12 million are related to below investment grade fixed income securities. Of these amounts, $4 million are related to below investment grade fixed income securities that had been in an unrealized loss position greater than or equal to 20% of amortized cost for a period of twelve or more consecutive months as of March 31, 2018.

ABS, RMBS and CMBS 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

First Quarter 2018 Form 10-Q 17

Notes to Condensed Consolidated Financial Statements

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, 2018, 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.

Limited partnerships

Investments in limited partnership interests include interests in private equity funds, real estate funds and other funds. As of March 31, 2018 and December 31, 2017, the carrying value of EMA limited partnerships totaled $5.77 billion and $5.41 billion, respectively, and limited partnerships carried at fair value as of March 31, 2018, while at cost method as of December 31, 2017, totaled $1.66 billion and $1.33 billion, respectively.

Mortgage loans

Mortgage loans are evaluated for impairment on a specific loan basis through a quarterly credit monitoring process and review of key credit quality indicators. Mortgage loans are considered impaired when it is probable that the Company will not collect the contractual principal and interest. Valuation allowances are established for impaired loans to reduce the carrying value to the fair value of the collateral less costs to sell or the present value of the loan’s expected future repayment cash flows

discounted at the loan’s original effective interest rate. Impaired mortgage loans may not have a valuation allowance when the fair value of the collateral less costs to sell is higher than the carrying value. Valuation allowances are adjusted for subsequent changes in the fair value of the collateral less costs to sell or present value of the loan’s expected future repayment cash flows. Mortgage loans are charged off against their corresponding valuation allowances when there is no reasonable expectation of recovery. The impairment evaluation is non-statistical in respect to the aggregate portfolio but considers facts and circumstances attributable to each loan. It is not considered probable that additional impairment losses, beyond those identified on a specific loan basis, have been incurred as of March 31, 2018.

Accrual of income is suspended for mortgage loans that are in default or when full and timely collection of principal and interest payments is not probable. Cash receipts on mortgage loans on nonaccrual status are generally recorded as a reduction of carrying value.

Debt service coverage ratio is considered a key credit quality indicator when mortgage loans are evaluated for impairment. Debt service coverage ratio represents the amount of estimated cash flows from the property available to the borrower to meet principal and interest payment obligations. Debt service coverage ratio estimates are updated annually or more frequently if conditions are warranted based on the Company’s credit monitoring process.

Mortgage loans with a debt service coverage ratio below 1.0 that are not considered impaired primarily relate to instances where the borrower has the financial capacity to fund the revenue shortfalls from the properties for the foreseeable term, the decrease in cash flows from the properties is considered temporary, or there are other risk mitigating circumstances such as additional collateral, escrow balances or borrower guarantees.

Note 6 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

First Quarter 2018 Form 10-Q 19

Notes to Condensed Consolidated Financial Statements

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. The first is where 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. The second situation where the Company classifies securities in Level 3 is where 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 investments such as mortgage loans, bank loans, agent loans and policy loans. Accordingly, such investments are only included in the fair value hierarchy disclosure when the investment is subject to remeasurement at fair value after initial recognition and the resulting remeasurement is reflected in the condensed consolidated financial statements.

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 valuation techniques for assets and liabilities measured at fair value on a recurring basis

Level 1 measurements

• Fixed income securities: Comprise certain U.S. Treasury fixed income securities. Valuation is based on unadjusted quoted prices for identical assets in active markets that the Company can access.

• Equity securities: Comprise actively traded, exchange-listed equity securities. Valuation is based on unadjusted quoted prices for identical assets in active markets that the Company can access.

• Short-term: Comprise U.S. Treasury bills valued based on unadjusted quoted prices for identical assets in active markets that the Company can access and actively traded money market funds that have daily quoted net asset values for identical assets that the Company can access.

• Separate account assets: Comprise actively traded mutual funds that have daily quoted net asset values that are readily determinable for identical assets that the Company can access. Net asset values for the actively traded mutual funds in which the separate account assets are invested are obtained daily from the fund managers.

Level 2 measurements

• Fixed income securities:

U.S. government and agencies: 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.

Municipal: 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 - public: 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: 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.

Foreign government: The primary inputs to the valuation include quoted prices for identical or similar assets in markets that are not active,

Notes to Condensed Consolidated Financial Statements

contractual cash flows, benchmark yields and credit spreads.

ABS - collateralized debt obligations (“CDO”) and ABS - consumer and other: 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, prepayment speeds, collateral performance and credit spreads. Certain ABS - CDO and ABS - consumer and other are valued based on non-binding broker quotes whose inputs have been corroborated to be market observable.

RMBS: 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, prepayment speeds, collateral performance and credit spreads.

CMBS: 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.

Redeemable preferred stock: 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, underlying stock prices and credit spreads.

• 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. For certain short-term investments, amortized cost is used as the best estimate of fair value.

• 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, 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, 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 in markets that exhibit less liquidity relative to those markets supporting Level 2 fair value measurements, 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 Corporate - privately placed: Primarily valued based on non-binding broker quotes where the inputs have not been corroborated to be market observable. Other inputs 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.

ABS - CDO, ABS - consumer and other, RMBS and CMBS: Valued based on non-binding broker quotes received from brokers who are familiar with the investments and where the inputs have not been corroborated to be market observable.

• Equity securities: The primary inputs to the valuation include quoted prices or quoted net asset values for identical or similar assets in markets that exhibit less liquidity relative to those markets supporting Level 2 fair value measurements.

• 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.

• Contractholder funds: Derivatives embedded in certain life and annuity contracts are valued internally using models widely accepted in the financial services industry that determine a single best estimate of fair value for the embedded derivatives within a block of contractholder liabilities. The models primarily use stochastically determined cash flows based on the contractual elements of embedded derivatives, projected option cost and applicable market data, such as interest rate yield curves and equity index volatility assumptions. These are categorized as Level 3 as a result of the significance of non-market observable inputs.

Assets and liabilities measured at fair value on a non-recurring basis

Mortgage loans written-down to fair value in connection with recognizing impairments are valued based on the fair value of the underlying collateral less costs to sell. EMA limited partnership interests written-down to fair value in connection with recognizing OTTI losses are generally valued using net asset values.

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. We

receive distributions of income and from liquidation of the underlying assets of the investees over the life of these investments, typically 10-12 years. As of March 31, 2018, the Company has commitments to invest $943 million in limited partnership interests valued using NAV.

The embedded derivatives are equity-indexed and forward starting options in certain life and annuity products that provide customers with interest crediting rates based on the performance of the S&P 500. If the projected option cost increased (decreased), it would result in a higher (lower) liability fair value.

As of March 31, 2018 and December 31, 2017, Level 3 fair value measurements of fixed income securities total $487 million and $606 million, respectively, and include $278 million and $271 million, respectively, of securities valued based on non-binding broker quotes where the inputs have not been corroborated to be

market observable and $54 million and $58 million, respectively, of municipal fixed income securities that are not rated by third party credit rating agencies.  The Company does not develop the unobservable inputs used in measuring fair value; therefore, these 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.

valuation source. Transfers in and out of level categorizations are reported as having occurred at the beginning of the quarter in which the transfer occurred. Therefore, for all transfers into Level 3, all realized and changes in unrealized gains and losses in

the quarter of transfer are reflected in the Level 3 rollforward table.

There were no transfers between Level 1 and Level 2 during the three months ended March 31, 2018 or 2017.

Transfers into Level 3 during the three months ended March 31, 2018 and 2017 included situations where a fair value quote was not provided by the Company’s independent third-party valuation service provider and as a result the price was stale or had been replaced with a broker quote where the inputs

had not been corroborated to be market observable resulting in the security being classified as Level 3. Transfers out of Level 3 during the three months ended March 31, 2018 and 2017 included situations where a broker quote was used in the prior period and a fair value quote became available from the Company’s independent third-party valuation service provider in the current period. A quote utilizing the new pricing source was not available as of the prior period, and any gains or losses related to the change in valuation source for individual securities were not significant.

Note 7 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 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 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. Credit default swaps are typically used to mitigate the credit risk within the Property-Liability fixed income portfolio. Equity index 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.

The Company utilizes several derivative strategies to manage risk in Allstate Life and Allstate Annuities. Asset-liability management is a risk management strategy that is principally employed by Allstate Life and Allstate Annuities to balance the respective interest-rate sensitivities of its assets and liabilities. Depending upon the attributes of the assets acquired and liabilities issued, derivative instruments such as interest rate swaps, caps, swaptions and futures are utilized to change the interest rate characteristics of existing assets and liabilities to ensure the relationship is maintained within specified ranges and to reduce exposure to rising or falling interest rates. Credit default swaps are typically used to mitigate the credit risk within the Allstate Life and Allstate Annuities fixed income portfolios. Futures and options are used for hedging the equity exposure contained in equity indexed life and annuity product contracts that offer equity returns to contractholders. In addition, the Company uses equity index futures to offset valuation losses in the equity portfolio during periods of declining equity market values. Foreign currency swaps and forwards are primarily used to reduce the foreign currency risk associated with holding foreign currency denominated investments.

The Company also has derivatives embedded in non-derivative host contracts that are 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. The Company’s primary embedded derivatives are equity options in life and annuity product contracts, which provide equity returns to contractholders.

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 Company designates certain investment risk transfer reinsurance agreements as fair value hedges when the hedging instrument is highly effective in offsetting the risk of changes in the fair value of the hedged item. The Company designates certain of its foreign currency swap contracts as cash flow hedges when the hedging instrument is highly effective in offsetting the exposure of variations in cash flows for the hedged risk that could affect net income. Amounts are reclassified to net investment income or realized capital gains and losses as the hedged item affects net income.

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 for fair value hedge accounting, net income includes the changes in the fair value of both the derivative instrument and the hedged risk, and therefore reflects any hedging ineffectiveness. 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

For the three months ended March 31, 2018 and 2017, the Company had no derivatives used in fair value hedging relationships.

The Company manages its exposure to credit risk by utilizing highly rated counterparties, establishing risk control limits, executing legally enforceable master netting agreements (“MNAs”) and obtaining collateral where appropriate. 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. As of March 31, 2018, counterparties pledged $8 million in cash to the Company, and the Company pledged $21 million in cash and securities to counterparties which includes $4 million of collateral posted under MNAs for contracts containing credit-risk-contingent provisions that are in a liability position and $17 million of collateral posted under MNAs for contracts without credit-risk-contingent features. 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.

For certain exchange traded and cleared derivatives, margin deposits are required as well as daily cash settlements of margin accounts. As of March 31, 2018, the Company pledged $15 million in the form of margin deposits.

Notes to Condensed Consolidated Financial Statements

Market risk is the risk that the Company will incur losses due to adverse changes in market rates and prices. 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 instruments contain credit-risk-contingent termination events, cross-default provisions and credit support annex agreements. Credit-risk-contingent termination events allow the counterparties to terminate the derivative agreement or a specific trade on certain dates if AIC’s, ALIC’s or Allstate Life Insurance

Company of New York’s (“ALNY”) 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. Credit-risk-contingent credit support annex agreements specify the amount of collateral the Company must post to counterparties based on AIC’s, ALIC’s or ALNY’s financial strength credit ratings by Moody’s or S&P, or in the event AIC, ALIC or ALNY are no longer rated by either Moody’s or S&P.

The following summarizes the fair value of derivative instruments with termination, cross-default or collateral credit-risk-contingent features that are in a liability position, as well as the fair value of assets and collateral that are netted against the liability in accordance with provisions within legally enforceable MNAs.

Credit derivatives - selling protection

A credit default swap (“CDS”) is a derivative instrument, representing an agreement between two parties to exchange the credit risk of a specified entity (or a group of entities), or an index based on the credit risk of a group of entities (all commonly referred to as the “reference entity” or a portfolio of “reference entities”), in return for a periodic premium. In selling

protection, CDS are used to replicate fixed income securities and to complement the cash market when credit exposure to certain issuers is not available or when the derivative alternative is less expensive than the cash market alternative. CDS typically have a five-year term.

In selling protection with CDS, the Company sells credit protection on an identified single name, a basket of names in a first-to-default (“FTD”) structure or credit derivative index (“CDX”) that is generally investment grade, and in return receives periodic premiums through expiration or termination of the agreement.

With single name CDS, this premium or credit spread generally corresponds to the difference between the yield on the reference entity’s public fixed maturity cash instruments and swap rates at the time the agreement is executed. With a FTD basket, because of the additional credit risk inherent in a basket of named

First Quarter 2018 Form 10-Q 31

Notes to Condensed Consolidated Financial Statements

reference entities, the premium generally corresponds to a high proportion of the sum of the credit spreads of the names in the basket and the correlation between the names. CDX is utilized to take a position on multiple (generally 125) reference entities. Credit events are typically defined as bankruptcy, failure to pay, or restructuring, depending on the nature of the reference entities. If a credit event occurs, the Company settles with the counterparty, either through physical settlement or cash settlement. In a physical settlement, a reference asset is delivered by the buyer of protection to the Company, in exchange for cash payment at par, whereas in a cash settlement, the Company pays the difference between par and the prescribed value of the reference asset. When a credit event occurs in a single name or FTD basket (for FTD,

the first credit event occurring for any one name in the basket), the contract terminates at the time of settlement. For CDX, the reference entity’s name incurring the credit event is removed from the index while the contract continues until expiration. The maximum payout on a CDS is the contract notional amount. A physical settlement may afford the Company with recovery rights as the new owner of the asset.

The Company monitors risk associated with credit derivatives through individual name credit limits at both a credit derivative and a combined cash instrument/credit derivative level. The ratings of individual names for which protection has been sold are also monitored.

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. In the normal course of business, 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 incurred but not reported (“IBNR”) losses, the establishment of appropriate reserves, including reserves for catastrophes and reserves and reinsurance recoverables for the Discontinued Lines and Coverages, 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 current reporting period as it contains the greatest proportion of losses that have not been reported or settled. 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 prior year 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 reinsurance 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, technology, laws and regulations.

Allstate’s reserves for asbestos claims were $866 million and $884 million, net of reinsurance recoverables of $399 million and $412 million, as of March 31, 2018 and December 31, 2017, respectively. Reserves for environmental claims were $162 million and $166 million, net of reinsurance recoverables of $33 million and $33 million, as of March 31, 2018 and December 31, 2017, respectively.

This expense includes losses from catastrophes of $361 million and $781 million in the three months ended March 31, 2018 and 2017, respectively, net of reinsurance and other recoveries. Catastrophes are an inherent risk of the property and casualty insurance business that have contributed to, and will continue to contribute to, material year-to-year fluctuations in the Company’s results of operations and financial position. During the three months ended March 31, 2018, incurred claims and claims expense included $51

million of prior year reserve reestimates, increasing net income. Prior year reserve reestimates excluding catastrophes is comprised of net decreases in auto reserves of $73 million, due to auto liability coverages development, and net increases primarily related to commercial lines of $18 million. Incurred claims and claims expense includes unfavorable catastrophe loss reestimates of $4 million, net of reinsurance and other recoveries, which include $34 million of unfavorable reestimates related to homeowners and $30 million of favorable reestimates, primarily related to auto.

Debt On March 29, 2018, the Company issued $250 million of Floating Rate Senior Notes due 2021 (“2021 Senior Notes”) and $250 million of Floating Rate Senior Notes due 2023 (“2023 Senior Notes” and, together with the 2021 Senior Notes, the “Senior Notes”). The 2021 Senior Notes bear interest at a floating rate equal to three-month LIBOR, reset quarterly on each interest reset date, plus 0.43% per

year and the 2023 Senior Notes bear interest at a floating rate equal to three-month LIBOR, reset quarterly on each interest reset date, plus 0.63% per year.  The Company will pay interest on the Senior Notes quarterly in arrears on March 29, June 29, September 29 and December 29 of each year, beginning on June 29, 2018.  The 2021 Senior Notes will mature on March 29, 2021, and the 2023 Senior Notes

will mature on March 29, 2023. The Senior Notes will not be redeemable prior to the applicable maturity dates.

Preferred stock On March 29, 2018, the Company issued 23,000 shares of 5.625% Fixed Rate Noncumulative Perpetual Preferred Stock, Series G, with a $1.00 par value per share and a liquidation preference of $25,000 per share, for gross proceeds of $575 million. The preferred stock is perpetual and has no maturity date. The preferred stock is redeemable at the Company’s option in whole or in part, on or after April 15, 2023 at a redemption price of $25,000 per share, plus declared and unpaid dividends. Prior to April 15, 2023, the preferred stock is redeemable at the Company’s option, in whole but not in part, within 90 days of the occurrence of certain rating agency events at a redemption price equal to $25,000 per share, plus declared and unpaid dividends.

The proceeds of Senior Notes and Preferred Stock issuances will be used for general corporate purposes,

including the redemption, repayment or repurchase of certain preferred stock or debt.

On April 30, 2018, the Company filed a universal shelf registration statement with the Securities and Exchange Commission that expires in 2021. The registration statement covers an unspecified amount of securities and can be used to issue debt securities, common stock, preferred stock, depositary shares, warrants, stock purchase contracts, stock purchase units and securities of trust subsidiaries.

Redemption of Debentures On April 13, 2018, the Company called for the redemption of its $224 million Series B 6.125% Fixed-to-Floating Rate Junior Subordinated Debentures (the “Subordinated Debentures”). The Subordinated Debentures will be redeemed on May 13, 2018 at a redemption price equal to 100% of the outstanding principal of $224 million plus accrued and unpaid interest of $2 million.

Note 11 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 employee severance and relocation benefits, and post-exit rent expenses in connection with these programs, and non-cash charges resulting from pension benefit payments made to agents and certain legal expenses and settlements incurred in connection with the 1999 reorganization of Allstate’s multiple

agency programs to a single exclusive agency program. The expenses related to these activities are included in the Condensed Consolidated Statements of Operations as restructuring and related charges, and totaled $22 million and $10 million during the three months ended March 31, 2018 and 2017, respectively. Restructuring expenses in 2018 primarily related to realignment of certain employees to centralized talent centers as well as legal expenses and settlements.

⁽¹⁾  Certain expenses are expensed as incurred and are not included as part of changes in the restructuring liability. During the three months ended March 31, 2018, these expenses totaled $3 million.

The payments applied against the liability for employee costs primarily reflect severance costs, and the payments for exit costs generally consist of post-exit rent expenses and contract termination penalties.

As of March 31, 2018, the cumulative amount incurred to date for active programs totaled $113 million for employee costs and $109 million for exit costs.

Note 12 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. Underwriting results related to these arrangements, which tend to be adverse, have been immaterial to the Company’s results of operations. Because of the Company’s participation, it may be exposed to losses that surpass the capitalization of

these facilities and/or assessments from these facilities.

Guarantees

Related to the sale of Lincoln Benefit Life Company (“LBL”) on April 1, 2014, ALIC agreed to indemnify Resolution Life Holdings, Inc. in connection with certain representations, warranties and covenants of ALIC, and certain liabilities specifically excluded from the transaction, subject to specific contractual limitations regarding ALIC’s maximum obligation.

First Quarter 2018 Form 10-Q 34

Notes to Condensed Consolidated Financial Statements

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 disposal through reinsurance of substantially all of its variable annuity business to Prudential in 2006, the Company and its consolidated subsidiaries, ALIC and ALNY, have agreed to indemnify Prudential for certain pre-closing contingent liabilities (including extra-contractual liabilities of ALIC and ALNY and liabilities specifically excluded from the transaction) that ALIC and ALNY have agreed to retain. In addition, the Company, ALIC and ALNY will each indemnify Prudential for certain post-closing liabilities that may arise from the acts of ALIC, ALNY and their agents, including certain liabilities arising from ALIC’s and ALNY’s provision of transition services. The reinsurance agreements contain no limitations or indemnifications with regard to insurance risk transfer and transferred all of the future risks and responsibilities for performance on the underlying variable annuity contracts to Prudential, including those related to benefit guarantees. Management does not believe this agreement will have a material effect on results of operations, cash flows or financial position of the Company.

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.

The aggregate liability balance related to all guarantees was not material as of March 31, 2018.

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 agent 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, the Financial Industry Regulatory Authority, the Department of Labor, 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.

First Quarter 2018 Form 10-Q 35

Notes to Condensed Consolidated Financial Statements

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 $150 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 case of Jack Jimenez, et al. v. Allstate Insurance Company was filed in the U.S. District Court for the Central District of California in September 2010. Plaintiffs allege off-the-clock wage and hour claims and other California Labor Code violations resulting from purported unpaid overtime. Plaintiffs seek recovery of unpaid compensation, liquidated damages, penalties, and attorneys’ fees and costs. The court certified a class that includes all adjusters in the state of California, except auto field adjusters, from September 29, 2006 to final judgment. Allstate’s appeals to the Ninth Circuit Court of Appeals and then to the U.S. Supreme Court did not result in decertification. No trial date is calendared.

The case of Maria Victoria Perez and Kaela Brown, et al. v. Allstate Insurance Company was filed in the U.S. District Court for the Eastern District of New York in April 2011. Plaintiffs allege that no-fault claim adjusters have been improperly classified as exempt employees under New York Labor Law and the Fair Labor Standards Act. Plaintiffs seek unpaid wages, liquidated damages, injunctive relief, compensatory and punitive damages, and attorneys’ fees. On September 16, 2014, the court certified a class of no-fault adjusters under New York Labor Law and refused to decertify a Fair Labor Standards Act class of no-fault adjusters. The parties have concluded discovery and the court scheduled a jury trial on June 25, 2018.

Other proceedings The Company is defending a consolidated proceeding relating to the reorganization of its agent sales force in 2000, when the Company discontinued employee agent programs, terminated the contracts of its employee agents, and offered those agents the opportunity to become Allstate Exclusive Agent independent contractors or to take severance benefits in exchange for a release of claims. The consolidated proceeding, captioned Gene Romero, et al. v. Allstate Insurance Company, et al., is pending in the United States District Court for the Eastern District of Pennsylvania. The consolidated proceeding includes three separate cases filed in August 2001, December 2001, and December 2003.

The Court opted to resolve these proceedings in 4 phases. Phases 1, 2 and 3 are complete although the Company awaits final disposition in Phase 1. On January 30, 2018, the court decided two summary judgment motions filed by Allstate with respect to the Phase 4 claims. The court (i) granted summary judgment in Allstate’s favor on the claims by twenty-seven Phase 4 plaintiffs alleging that Allstate improperly retaliated against them by filing counterclaims to their original complaint; and (ii) declined to decide whether the remaining Phase 4 plaintiffs’ age discrimination (disparate treatment) claims should be dismissed due to their failure to exhaust administrative remedies.

In March 2018, the Company reached agreements to settle the claims of additional plaintiffs on a confidential basis, subject to negotiating and executing appropriate written settlement agreements, resulting in a total of 457 individual settlements to date. As a result of these settlements, plus several voluntary and involuntary dismissals of individual plaintiffs’ claims, there are 36 individual plaintiffs with claims remaining in the litigation. On April 11, 2018, the Company filed a motion for summary judgment as to the state law breach of contract and breach of fiduciary duty claims for fourteen of the remaining plaintiffs asserting that those claims are barred by statutes of limitations.

The court has established a Phase 4 schedule contemplating resolving this matter through trial, if necessary, by the end of 2018. The court has yet to decide the proper venue for such trials. The final resolution of these matters is subject to various uncertainties and complexities including how trials, post-trial motions, possible appeals with respect to the validity of the release, and any rulings on the merits will be resolved.

The two shareholder derivative actions described below are disclosed pursuant to SEC disclosure requirements for these types of matters, and the putative class action has been disclosed because these matters involve similar allegations.

In Biefeldt v. Wilson, et al., a plaintiff alleging to be a stockholder in the Company filed a shareholder derivative complaint in the Circuit Court for Cook County, Illinois, Chancery Division on August 3, 2017. The plaintiff seeks, on behalf of the Company, an unspecified amount of damages and various forms of equitable relief. The complaint alleges breaches of fiduciary duty based on allegations similar to those asserted in Inre The Allstate Corp. Securities Litigation. The complaint names as defendants the Company’s chairman and chief executive officer, its former president, its former chief financial officer, who is now the Company’s vice chairman, and the members of the board of directors during the relevant period. The defendants’ motion to dismiss the complaint is scheduled to be heard on May 8, 2018.

In IBEW Local No. 98 Pension Fund v. Wilson, et al., another plaintiff alleging to be a stockholder in the Company filed a shareholder derivative complaint in the Circuit Court for Cook County, Illinois, Chancery Division on April 12, 2018. The plaintiff seeks, on behalf of the Company, an unspecified amount of damages and various forms of equitable relief. The complaint alleges breaches of fiduciary duty based on allegations similar to those asserted in Inre The Allstate Corp. Securities Litigation. The complaint also includes allegations concerning the exercise of stock options by the Company’s chairman and several other members of our board of directors during the relevant period.  The complaint names as defendants the Company’s chairman and chief executive officer, its former president and the members of the board of directors during the relevant period.

First Quarter 2018 Form 10-Q 37

Notes to Condensed Consolidated Financial Statements

Inre The Allstate Corp. Securities Litigation is a putative class action filed in November 2016 in the United States District Court for the Northern District of Illinois against the Company and several of its officers asserting claims under the federal securities laws. Plaintiffs seek an unspecified amount of damages, costs, attorney’s fees, and such 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.

Plaintiffs’ further allege that a senior officer engaged in stock option exercises and sales during that time allegedly while in possession of nonpublic information about claim frequency. The Company, its chairman and chief executive officer and its former president are the named defendants. Defendants answered the complaint, disputing plaintiffs’ allegations that there was any misstatement or omission or other misconduct, after the court denied their motion to dismiss on February 27, 2018.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of

The Allstate Corporation

Northbrook, Illinois 60062

Results of Review of Interim Financial Information

We have reviewed the accompanying condensed consolidated statement of financial position of The Allstate Corporation and subsidiaries (the “Company”) as of March 31, 2018, the related condensed consolidated statements of operations, comprehensive income, shareholders’ equity and cash flows for the three-month periods ended March 31, 2018 and 2017 and the related notes (collectively referred to as the “condensed consolidated financial statements”). Based on our reviews, we are not aware of any material modifications that should be made to the accompanying condensed consolidated financial statements for them to be in conformity with accounting principles generally accepted in the United States of America.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the consolidated statement of financial position of The Allstate Corporation and subsidiaries as of December 31, 2017, and the related consolidated statements of operations, comprehensive income, shareholders’ equity, and cash flows for the year then ended (not presented herein); and in our report dated February 26, 2018, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated statement of financial position as of December 31, 2017 is fairly stated, in all material respects, in relation to the consolidated statement of financial position from which it has been derived.

Basis for Review Results

These condensed consolidated financial statements are the responsibility of the Company's management. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our reviews in accordance with standards of the PCAOB. A review of the condensed consolidated financial statements consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the PCAOB, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Emphasis of a Matter

As discussed in Note 1 to the condensed consolidated financial statements, the Company changed its presentation and method of accounting for the recognition and measurement of financial assets and financial liabilities due to an adopted accounting standard.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations for the Three-Month Periods Ended March 31, 2018 and 2017

Overview

To achieve its goals in 2018, Allstate is focused on the following priorities:

•  Better serve customers

• Achieve target economic returns on capital

• Grow customer base

• Proactively manage investments

• Build long-term growth platforms

The following discussion highlights significant factors influencing the consolidated financial position and results of operations of The Allstate Corporation (referred to in this document as “we,” “our,” “us,” the “Company” or “Allstate”). It should be read in conjunction with the condensed consolidated financial statements and notes thereto found under Part I. Item 1. contained herein, and with the discussion, analysis, consolidated financial statements and notes thereto in Part I. Item 1. and Part II. Item 7. and Item 8. of The Allstate Corporation annual report on Form 10-K for 2017. Further analysis of our insurance segments is provided in the Property-Liability Operations and Segment Results sections, including Allstate Protection, Service Businesses, Allstate Life, Allstate Benefits, and Allstate Annuities, of Management’s Discussion and Analysis (“MD&A”). The segments are consistent with the way in which the chief operating decision maker reviews financial performance and makes decisions about the allocation of resources.

Measuring segment profit or loss

The measure of segment profit or loss used in evaluating performance is underwriting income for the Allstate Protection and Discontinued Lines and Coverages segments and adjusted net income for the Service Businesses, Allstate Life, Allstate Benefits, Allstate Annuities, and Corporate and Other segments.

Underwriting income is calculated as premiums earned and other revenue, less claims and claims expense (“losses”), amortization of deferred policy acquisition costs (“DAC”), operating costs and expenses and restructuring and related charges, as determined using accounting principles generally accepted in the United States of America (“GAAP”). We use this measure in our evaluation of results of operations to analyze the profitability of the Property-Liability insurance operations separately from investment results. Underwriting income is reconciled to net income applicable to common shareholders in the Property-Liability Operations section of Management’s Discussion and Analysis (“MD&A”).

Adjusted net income is net income applicable to common shareholders, excluding:

•  Realized capital gains and losses, after-tax, except for periodic settlements and accruals on non-hedge derivative instruments, which are reported with realized capital gains and losses but included in adjusted net income

• Valuation changes on embedded derivatives not hedged, after-tax

• Amortization of DAC and deferred sales inducement costs (“DSI”), to the extent they resulted from the recognition of certain realized capital gains and losses or valuation changes on embedded derivatives not hedged, after-tax

• Business combination expenses and the amortization of purchased intangible assets, after-tax

• Gain (loss) on disposition of operations, after-tax

• 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

Adjusted net income is reconciled to net income applicable to common shareholders in the Service Businesses, Allstate Life, Allstate Benefits and Allstate Annuities Segment sections of MD&A.

First Quarter 2018 Form 10-Q 41

Highlights

Consolidated Net Income

($ in millions)

First quarter 2018 vs. 2017 - Increase was primarily due to lower catastrophe losses, higher Allstate Protection insurance premiums, lower claim frequency, a lower effective tax rate from the Tax Legislation and higher net investment income, partially offset by net realized capital losses compared to net realized capital gains in the prior period. The Property-Liability combined ratio was 88.0 compared to 92.9.

Total Revenue

($ in billions)

First quarter 2018 vs. 2017 - Increase was primarily due to higher Allstate Protection insurance premiums and higher net investment income, partially offset by net realized capital losses compared to net realized capital gains in the prior period.

Net Investment Income

($ in millions)

First quarter 2018 vs. 2017 - The increase benefited from performance-based investment results, primarily from limited partnerships, partially offset by lower market-based portfolio income and higher expenses.

Allstate Protection underwriting income totaled $962 million in the first quarter of 2018, a 74.9% increase from $550 million in the first quarter of 2017, primarily due to lower catastrophe losses, increased premiums earned and lower claim frequency, partially offset by higher operating costs and expenses, higher claim severity and lower favorable prior year reserve reestimates.Premiums written increased 5.0% to $7.84 billion.

Service Businessesadjusted net loss was $5 million in the first quarter of 2018 compared to $10 million in the first quarter of 2017. The improvement was primarily due to improved loss experience at SquareTrade, partially offset by investments in research and business expansion at Arity.Total revenues increased 26.7% to $313 million. Net investment income increased 66.7% to $5 million.

Allstate Life adjusted net income was $69 million in the first quarter of 2018 compared to $59 million in the first quarter of 2017. The increase was primarily due to

a lower effective tax rate from the Tax Legislation and higher premiums and contract charges, partially offset by higher contract benefits. Premiums and contract charges increased1.9% to $327 million.

Allstate Benefits adjusted net income was $28 million in the first quarter of 2018 compared to $22 million in the first quarter of 2017. The increase was primarily due to higher premiums and contract charges, partially offset by higher contract benefits. Premiums and contract charges increased6.3% to $286 million.

Allstate Annuities adjusted net income was $35 million in 2018 compared to $29 million in 2017. The increase was primarily due to lower interest credited to contractholder funds and a lower effective tax rate from the Tax Legislation, partially offset by higher contract benefits. Net investment income increased0.3% to $290 million.

Financial Highlights

Tax Reform On December 22, 2017, Public Law 115-97, known as the Tax Cuts and Jobs Act of 2017 (“Tax Legislation”) became effective, permanently reducing the U.S. corporate income tax rate from 35% to 21% beginning January 1, 2018. The decrease in the effective tax rate will impact the comparative trends.

We anticipate utilizing a portion of the benefits from the Tax Legislation for the following initiatives:

• Accelerate growth initiatives

• Further enhance our employee value proposition

• Improve local communities

• Increase our target quarterly dividend per common share

The expenses associated with these initiatives will occur throughout 2018 and certain costs will reoccur in future periods.

Investment in our people In the first quarter of 2018, employees received either $1,000 or $2,000 of Choice Dollars (“Choice Dollars”) following a reduction in the federal tax rate, which could be taken as a cash bonus or contributed to a 401(k) or health savings account. $43 million was recorded as an expense with $21 million recorded in claims and claim expense and $22 million recorded in other costs and expenses. We expect these costs to reoccur as a component of our compensation costs in future years.

Investments totaled $83.29 billion as of March 31, 2018, increasing from $82.80 billion as of December 31, 2017.

Shareholders’ equity As of March 31, 2018, shareholders’ equity was $23.28 billion. This total included $3.86 billion in deployable assets at the parent holding company level comprising cash and investments that are generally saleable within one quarter.

Book value per diluted common share (ratio of common shareholders’ equity to total common shares outstanding and dilutive potential common shares outstanding) was $58.64 as of March 31, 2018, an increase of 11.9% from $52.41 as of March 31, 2017, and an increase of 1.8% from $57.58 as of December 31, 2017.

Return on average common shareholders’ equity For the twelve months ended March 31, 2018, return on the average of beginning and ending period common shareholders’ equity of 16.6% increased by 5.0 points from 11.6% for the twelve months ended March 31, 2017.

Adopted Accounting Standards

Recognition and Measurement of Financial Assets and Financial Liabilities (“recognition and measurement accounting standard”)Beginning January 1, 2018, equity securities are reported at fair value with changes in fair value recognized in realized capital gains and losses.

Limited partnerships previously reported using the cost method are now reported at fair value with changes in fair value recognized in net investment income. See the Investments section of this Item for further details related to the adoption.

Revenue from Contracts with Customers Beginning January 1, 2018, we adopted the revenue from contracts with customers accounting standard, which revises the criteria for revenue recognition and impacted the Service Businesses segment by increasing deferred revenue by approximately $160 million with a corresponding increase in DAC for protection plans that are sold directly to retailers. The anticipated impacts of these adjustments offset and will not impact net income, but will impact premiums and DAC comparability trends as they are recognized over the life of the policy.

See Note 1 of the condensed consolidated financial statements for additional details on the adopted accounting standards.

Other revenue presentation

Concurrent with the adoption of the Financial Accounting Standards Board’s (“FASB”) standard on revenue from contracts with customers and our objective of providing more information related to revenues for our Services Businesses, we revised the presentation of total revenue to include other revenue. Previously, components of other revenue were presented within operating costs and expenses and primarily represent fees collected from policyholders relating to premium installment payments, commissions on sales of non-proprietary products, fee-based services and other revenue transactions. Other revenue is recognized when performance obligations are fulfilled. Prior periods have been reclassified to conform to current separate presentation of other revenue.

Property-Liability Operations

Property-Liability Operations

Overview Our Property-Liability operations consist of two reportable segments: Allstate Protection and Discontinued Lines and Coverages. These segments are consistent with the groupings of financial information that management uses to evaluate performance and to determine the allocation of resources.

We do not allocate Property-Liability investment income, realized capital gains and losses, or assets to the Allstate Protection and Discontinued Lines and Coverages segments. Management reviews assets at the Property-Liability level for decision-making purposes.

The table below includes GAAP operating ratios we use to measure our profitability. We believe that they enhance an investor’s understanding of our profitability. They are calculated as follows:

• Loss ratio: the ratio of claims and claims expense to premiums earned. Loss ratios include the impact of catastrophe losses.

• Expense ratio: the ratio of amortization of DAC, operating costs and expenses and restructuring and related charges, less other revenue to premiums earned.

• Combined ratio: the ratio of claims and claims expense, amortization of DAC, operating costs and expenses, and restructuring and related charges, less other revenue to premiums earned. The combined ratio is the sum of the loss ratio and the expense ratio. The difference between 100% and the combined ratio represents underwriting income as a percentage of premiums earned, or underwriting margin.

We have also calculated the following impacts of specific items on the GAAP operating ratios because of the volatility of these items between fiscal periods.

• Effect of catastrophe losses on combined ratio: the ratio of catastrophe losses included in claims and claims expense to premiums earned. This ratio includes prior year reserve reestimates of catastrophe losses.

• Effect of prior year reserve reestimates on combined ratio: the ratio of prior year reserve reestimates included in claims and claims expense to premiums earned. This ratio includes prior year reserve reestimates of catastrophe losses.

• Effect of amortization of purchased intangible assets on combined ratio: the ratio of amortization of purchased intangible assets to premiums earned. Amortization of purchased intangible assets is reported in operating costs and expenses on the Condensed Consolidated Statements of Operations.

• Effect of restructuring and related charges on combined ratio: the ratio of restructuring and related charges to premiums earned.

• Effect of Discontinued Lines and Coverages on combined ratio: the ratio of claims and claims expense and operating costs and expenses in the Discontinued Lines and Coverages segment to Property-Liability premiums earned. The sum of the effect of Discontinued Lines and Coverages on the combined ratio and the Allstate Protection combined ratio is equal to the Property-Liability combined ratio.

Allstate Protection Segment Results

Underwriting income totaled $962 million in the first quarter of 2018 compared to $550 million in the first quarter of 2017. The increase was primarily due to lower catastrophe losses, increased premiums earned and lower claim frequency, partially offset by higher operating costs and expenses, higher claim severity and lower favorable prior year reserve reestimates.

Premiums written is the amount of premiums charged for policies issued during a fiscal period. Premiums are considered earned and are included in the financial results on a pro-rata basis over the policy period. The portion of premiums written applicable to the unexpired term of the policies is recorded as unearned premiums on our Condensed Consolidated Statements of Financial Position.

First Quarter 2018 Form 10-Q 49

Segment Results Allstate Protection

Catastrophe losseswere $361 million in the first quarter of 2018 compared to $781 million in the first quarter of 2017. Catastrophe losses in first quarter 2017 were impacted by higher than historical first quarter catastrophe losses.

Loss estimates are generally based on claim adjuster inspections and the application of historical loss development factors. Our loss estimates are calculated in accordance with the coverage provided by our policies. Auto policyholders generally have coverage for physical damage due to flood if they have purchased optional auto comprehensive coverage. Our homeowners policies specifically exclude coverage for losses caused by flood.

Over time, we have limited our aggregate insurance exposure to catastrophe losses in certain regions of the country that are subject to high levels of natural catastrophes through reinsurance and

underwriting guidelines, limited by our participation in various state facilities.

We define a “catastrophe” as an event that produces pre-tax losses before reinsurance in excess of $1 million and involves multiple first party policyholders, or a winter weather event that produces a number of claims in excess of a preset, per-event threshold of average claims in a specific area, occurring within a certain amount of time following the event. Catastrophes are caused by various natural events including high winds, winter storms and freezes, tornadoes, hailstorms, wildfires, tropical storms, tsunamis, hurricanes, earthquakes and volcanoes. We are also exposed to man-made catastrophic events, such as certain types of terrorism or industrial accidents. The nature and level of catastrophes in any period cannot be reliably predicted.

Catastrophe reinsuranceOur catastrophe reinsurance program supports our goal to have no more than a 1% likelihood of exceeding average annual aggregate catastrophe losses by $2 billion, net of reinsurance, from hurricanes and earthquakes, based on modeled assumptions and applications currently used. Except for the Florida component of the program and the Aggregate Excess Catastrophe Reinsurance Contract - Automobile - Florida and Southeast States that are expected to be placed in the second quarter of 2018, we have substantially completed the placement of our 2018 catastrophe reinsurance program.

Similar to our 2017 program, our 2018 program includes coverage for losses to personal lines property and automobile arising out of multiple perils, in

addition to hurricanes and earthquakes, in all agreements, except for two agreements placed in the insurance linked securities (“ILS”) market, forming part of our nationwide reinsurance program, and the Kentucky agreement.

The June 1, 2018 nationwide reinsurance program, excluding New Jersey and property business in the state of Florida where separate reinsurance agreements address the distinct needs of our separately capitalized legal entities in these states, provides $4.5 billion of reinsurance limits, less a $500 million retention, subject to the percentage of reinsurance placed in each of its nine layers. The nationwide reinsurance program includes reinsurance agreements with both the traditional and ILS markets as described below:

50www.allstate.com

Allstate Protection Segment Results

The traditional market placement provides limits totaling $2.6 billion for losses arising out of multiple perils and is comprised of $2.1 billion of limits with one annual reinstatement of limits; $439 million of limits with one reinstatement of limits over a seven year term; and $69 million of limits not subject to reinstatement.

ILS placements provide $1.2 billion of limits, with no reinstatement of the limits, and are comprised of a $305 million placement reinsuring losses in certain states caused by hurricanes, earthquakes and fire following earthquakes with amounts payable based on insured industry losses and further adjusted to account for our exposures in reinsured areas; $375 million placement reinsuring losses in all states except Florida and New Jersey caused by named storms, earthquakes and fire following earthquakes, severe thunderstorms, winter storms, volcanic eruptions, and meteorite impacts; and a $500 million placement reinsuring losses in all states except Florida and New Jersey caused by named storms, earthquakes and fire following earthquakes, severe weather, wildfires, and other naturally occurring or man-made events determined to be a catastrophe by the Company. The $500 million placement also provides coverage on two or more events that can be aggregated to erode the aggregate retention and qualify for coverage under the aggregate limit. Recoveries are limited to our ultimate net loss from the reinsured event.

The New Jersey agreement comprises three contracts that reinsure personal lines property and automobile catastrophe losses caused by multiple perils in New Jersey and provides 95% of $400 million of limits excess of provisional retentions of approximately $144 million. Each contract includes one annual reinstatement of limits.

The Kentucky Earthquake agreement comprises a three-year term contract that reinsures personal lines property losses caused by earthquakes and fire following earthquakes in Kentucky and provides $28 million of limits in excess of a $2 million retention.

The total cost of our property catastrophe reinsurance programs during the first quarter of 2018 and 2017 were $85 million and $93 million, respectively. The decrease is related to lower costs in Allstate brand homeowners, partially offset by costs related to Aggregate Excess Catastrophe Reinsurance Contract - Automobile - Florida and Southeast States that became effective on June 1, 2017. The total cost of our catastrophe reinsurance programs during 2017 was $355 million or an average quarterly cost of $89 million.

Expense ratio increased 0.7 points in the first quarter of 2018 compared to the same period of 2017.

When analyzing premium measures and statistics for all three brands the following calculations are used as described below.

• PIF: Policy counts are based on items rather than customers. A multi-car customer would generate multiple item (policy) counts, even if all cars were insured under one policy.

• New issued applications: Item counts of automobile or homeowner insurance applications for insurance policies that were issued during the period, regardless of whether the customer was previously insured by another Allstate Protection brand. Allstate brand includes automobiles added by existing customers when they exceed the number allowed (currently 10) on a policy.

• Average premium-gross written (“average premium”): Gross premiums written divided by issued item count. Gross premiums written include the impacts from discounts, surcharges and ceded reinsurance premiums and exclude the impacts from mid-term premium adjustments and premium refund accruals. Average premiums represent the appropriate policy term for each line. Allstate and Esurance brand policy terms are 6 months for auto and 12 months for homeowners. Encompass brand policy terms are 12 months for auto and homeowners.

• Renewal ratio: Renewal policies issued during the period, based on contract effective dates, divided by the total policies issued 6 months prior for auto (generally 12 months prior for Encompass brand) or 12 months prior for homeowners.

Auto loss ratio decreased 3.1 points in the first quarter of 2018 compared to the first quarter of 2017, primarily due to increased premiums earned, lower catastrophe losses and lower claim frequency, partially offset by higher claim severity. Frequency and severity statistics, which are influenced by driving patterns, inflation and other factors, are provided to describe the trends in loss costs of the business. Our reserving process incorporates changes in loss patterns, operational statistics and changes in claims reporting processes to determine our best estimate of recorded reserves.

Paid claim frequency is calculated as annualized notice counts closed with payment in the period divided by the average of policies in force with the applicable coverage during the period.

Gross claim frequency is calculated as annualized notice counts received in the period divided by the average of policies in force with the applicable coverage during the period. Gross claim frequency includes all actual notice counts, regardless of their current status (open or closed) or their ultimate disposition (closed with a payment or closed without payment). Frequency statistics exclude counts associated with catastrophe events.

The percent change in paid or gross claim frequency is calculated as the amount of increase or decrease in the paid or gross claim frequency in the current period compared to the same period in the prior year; divided by the prior year paid or gross claim frequency.

Paid claim frequency trends will often differ from gross claim frequency trends due to differences in the timing of when notices are received and when claims are settled. For property damage claims, paid frequency trends reflect smaller differences as timing between opening and settlement is generally less. For bodily injury, gross frequency trends reflect emerging trends since the difference in timing between opening and settlement is much greater and gross frequency does not experience the same volatility in quarterly fluctuations seen in paid frequency. In evaluating frequency, we typically rely upon paid frequency trends for physical damage coverages such as property damage and gross frequency for casualty coverages such as bodily injury to provide an indicator of emerging trends in overall claim frequency while also providing insights for our analysis of severity.

Paid claim severity is calculated by dividing the sum of paid losses and loss expenses by claims closed with a payment during the period. The percent change in paid claim severity is calculated as the amount of increase or decrease in paid claim severity in the current period compared to the same period in the prior year; divided by the prior year paid claims severity.

We are continuing to aggressively seek new technology and process solutions to provide continued loss cost accuracy, efficient processing and enhanced customer experiences that are simple, fast and produce high degrees of satisfaction. For example, we have opened several Digital Operating Centers to handle auto claims countrywide utilizing our virtual estimation capabilities, which includes estimating damage through photos and video with the use of QuickFoto Claim^®and Virtual Assist^SM. These organizational and process changes have been beneficial to our operations as they are occurring, but frequency and severity statistics may be impacted as changes in claim opening and closing practices, if any, can impact comparisons to prior periods.

Property damage paid claim frequency decreased 3.0% in the first quarter of 2018 compared to the first quarter of 2017. 38 states experienced a year over year decrease in property damage paid claim frequency in first quarter 2018 when compared to first quarter 2017.Property damage paid claim severities increased 4.7% in the first quarter of 2018 compared to the first quarter of 2017due to higher costs to repair more sophisticated, newer model vehicles and increased volume of total losses. 

Bodily injury gross claim frequency decreased 2.0% in the first quarter of 2018 compared to the first quarter of 2017. Bodily injury

paid claim frequency decreased 15.2% while bodily injury paid claim severity increased 15.8% in the first quarter of 2018 compared to the same period of 2017. Claim process changes in the second half of 2016 related to enhanced documentation of injuries and related medical treatments are having a related impact on paid claim frequency and severity due to payment mix and claim closure patterns.  These process changes and the related impacts on the percent change in paid claim frequency and severity have begun to moderate, but are still impacting comparative trends.

First Quarter 2018 Form 10-Q 57

Segment Results Allstate Protection: Allstate brand

Homeowners loss ratio decreased 13.1 points in the first quarter of 2018 compared to the first quarter of 2017, primarily due to lower catastrophe losses and increased premiums earned, partially offset by less favorable prior year reserve reestimates in first quarter 2018 compared to first quarter 2017. Paid claim frequency excluding catastrophe losses decreased 4.0% in the first quarter of 2018 compared to the first quarter of 2017. Paid claim severity excluding catastrophe losses increased 14.4% in the first quarter of 2018 compared to the first quarter of 2017, primarily due to a higher level of fire and water claims experienced in first quarter 2018, which typically have higher severities. Homeowner paid claim severity can be impacted by both the mix of perils and the magnitude of specific losses paid during the quarter.

Other personal lines loss ratiodecreased 4.0 points in the first quarter of 2018 compared to the first quarter of 2017, primarily due to lower catastrophe losses and increased premiums earned, partially offset by higher loss costs.

Commercial lines loss ratioincreased 2.6 points in the first quarter of 2018 compared to the first quarter of 2017, primarily due to higher unfavorable prior year reserve reestimates, partially offset by increased premiums earned and lower catastrophe losses.

Catastrophe losses were $329 million in the first quarter of 2018 compared to $706 million in the first quarter of 2017.

Net income applicable to common shareholders was $65 million in the first quarter of 2018 compared to $57 million in the first quarter of 2017.

Adjusted net income was $69 million in the first quarter of 2018 compared to $59 million in the first quarter of 2017. The increase was primarily due to a lower effective tax rate from the Tax Legislation and

higher premiums and contract charges, partially offset by higher contract benefits.

Premiums and contract chargesincreased 1.9% or $6 million in the first quarter of 2018 compared to the first quarter of 2017. The increase primarily relates to growth in traditional life insurance as well as lower levels of reinsurance premiums ceded.

Contract benefits increased 5.1% or $10 million in the first quarter of 2018 compared to the first quarter of 2017, primarily due to higher claim experience on both traditional and interest-sensitive life insurance.

Benefit spreadreflects our mortality and morbidity results using the difference between premiums and

contract charges earned for the cost of insurance and contract benefits (“benefit spread”). Benefit spread decreased 2.9% to $67 million in the first quarter of 2018 compared to $69 million in the first quarter of 2017, primarily due to higher claim experience, partially offset by growth in traditional life premiums.

Investment spread reflects the difference between net investment income and interest credited to contractholder funds (“investment spread”) and is used to analyze the impact of net investment income and interest credited to contractholder funds on net income. Investment spread increased 2.0% or $1 million to $52 million in the first quarter of 2018 compared to $51 million in the first quarter of 2017.

Amortization of DAC decreased 8.3% or $3 million in the first quarter of 2018 compared to the first quarter of 2017, primarily due to lower net realized capital gains and gross profits.

Net income applicable to common shareholders was $17 million in the first quarter of 2018 compared to $29 million in the first quarter of 2017.

Adjusted net income was $35 million in the first quarter of 2018 compared to $29 million in the first quarter of 2017. The increase was primarily due to lower interest credited to contractholder funds and a lower effective tax rate from the Tax Legislation, partially offset by higher contract benefits.

Net investment income increased 0.3% or $1 million in the first quarter of 2018 compared to the first quarter of 2017, primarily due to higher limited partnership income, partially offset by lower market-based portfolio income, including the impact of lower average investment balances.

Net realized capital losses in the first quarter of 2018 primarily related to declines in the valuation of equity investments.

Contract benefits increased 4.9% or $7 million in the first quarter of 2018 compared to the first quarter of 2017, primarily due to immediate annuity mortality experience.

Benefit spread reflects our mortality results using the difference between contract charges earned and contract benefits excluding the portion related to the implied interest on immediate annuities with life contingencies. This implied interest totaled $124 million and $126 million in the first quarter of 2018 and 2017, respectively. Total benefit spread was $(24) million and $(15) million in the first quarter of 2018 and 2017, respectively.

Interest credited to contractholder funds decreased 12.6% or $12 million in the first quarter of 2018 compared to the first quarter of 2017, primarily due to lower average contractholder funds. Valuation changes on derivatives embedded in equity-indexed annuity contracts that are not hedged decreased interest credited to contractholder funds by $4 million in the first quarter of 2018 and had no impact on interest credited to contractholder funds in the first quarter of 2017.

which is included as a component of contract benefits and is used to analyze the impact of net investment income and interest credited to contractholders on net income.

Investment spread before valuation changes on embedded derivatives not hedged increased 16.2% to $79 million in the first quarter of 2018 compared to $68 million the first quarter of 2017, primarily due to lower credited interest and higher investment income.

To further analyze investment spreads, the following table summarizes the weighted average investment yield on assets supporting product liabilities, interest crediting rates and investment spreads. Investment spreads may vary significantly between periods due to the variability in investment income, particularly for immediate fixed annuities where the investment portfolio includes performance-based investments.

Contractholder funds represent interest-bearing liabilities arising from the sale of products such as fixed annuities. The balance of contractholder funds is equal to the cumulative deposits received and interest credited to the contractholder less cumulative contract benefits, surrenders, withdrawals, maturities and contract charges for mortality or administrative expenses. The following table shows the changes in contractholder funds.

As a result, the net change in contractholder funds associated with products reinsured is reflected as a component of the other adjustments line.

Contractholder funds decreased 2.7% in the first quarter of 2018, primarily due to the continued runoff of our deferred fixed annuity business. We discontinued the sale of annuities over an eight year period from 2006 to 2014 but still accept additional deposits on existing contracts.

Contractholder deposits decreased $7 million in the first quarter of 2018 compared to the first quarter of 2017, primarily due to lower additional deposits on fixed annuities.

Surrenders and partial withdrawals increased 11.0% to $201 million in the first quarter of 2018 from $181 million in the first quarter of 2017. The annualized surrender and partial withdrawal rate on deferred fixed annuities, based on the beginning of year contractholder funds, was 10.7% in the first quarter of 2018 compared to 8.8% in the first quarter of 2017.

Investments totaled $83.29 billion as of March 31, 2018, increasing from $82.80 billion as of December 31, 2017, primarily due to the proceeds from the issuance of preferred stock and senior debt and positive operating cash flows, partially offset by lower fixed income and equity valuations, common share repurchases, net reductions in contractholder funds and dividends paid to shareholders.

Adopted Recognition and Measurement of Financial Assets and Financial Liabilities Beginning January 1, 2018, equity securities are reported at fair value with changes in fair value recognized in realized capital gains and losses.

Limited partnerships previously reported using the cost method are now reported at fair value with changes in fair value recognized in net investment income.

Portfolio composition by investment strategy We utilize two primary strategies to manage risks and returns and to position our portfolio to take advantage of market opportunities while attempting to mitigate adverse effects. As strategies and market conditions evolve, the asset allocation may change or assets may be moved between strategies.

Market-basedstrategies include investments primarily in public fixed income and equity securities. Market-based core seeks to deliver predictable earnings aligned to business needs and returns consistent with the markets in which we invest. Private fixed income assets, such as commercial mortgages, bank loans and privately placed debt that provide liquidity premiums are also included in this category. Market-based active seeks to outperform within the public markets through tactical positioning and by taking advantage of short-term opportunities. This category may generate results that meaningfully deviate from those achieved by market indices, both favorably and unfavorably.

Performance-basedstrategy seeks to deliver attractive risk-adjusted returns and supplement market risk with idiosyncratic risk primarily through investments in private equity and real estate.

Fixed income securities are rated by third party credit rating agencies and/or are internally rated. As of March 31, 2018, 88.4% of the consolidated fixed income securities portfolio was rated investment grade, which is defined as a security having a rating of Aaa, Aa, A or Baa from Moody’s, a rating of AAA, AA, A or BBB from S&P Global Ratings (“S&P”), a comparable rating from another nationally recognized rating agency, or a comparable internal rating if an externally provided rating is not available. Credit ratings below these

designations are considered low credit quality or below investment grade, which includes high yield bonds. Market prices for certain securities may have credit spreads which imply higher or lower credit quality than the current third party rating. Our initial investment decisions and ongoing monitoring procedures for fixed income securities are based on a thorough due diligence process which includes, but is not limited to, an assessment of the credit quality, sector, structure, and liquidity risks of each issue.

The RMBS portfolio is subject to interest rate risk, but unlike other fixed income securities, is additionally subject to prepayment risk from the underlying residential mortgage loans. RMBS consists of a U.S. Agency portfolio having collateral issued or guaranteed by U.S. government agencies and a non-agency portfolio consisting of securities collateralized by Prime, Alt-A and Subprime loans. The non-agency portfolio totaled $455 million as of March 31, 2018, with 6.2% rated investment grade and an unrealized net capital gain of $95 million.

CMBS totaled $99 million as of March 31, 2018, with 32.3% rated investment grade and an unrealized net capital gain of $4 million. The CMBS investments are primarily traditional conduit transactions collateralized by commercial mortgage loans, broadly diversified across property types and geographical area.

The consumer goods, utilities and capital goods sectors comprise 30%, 14% and 11%, respectively, of the carrying value of our corporate fixed income securities portfolio as of March 31, 2018. The consumer goods, utilities and capital goods sectors had the highest concentration of gross unrealized losses in our corporate fixed income securities portfolio as of March 31, 2018.

In general, the gross unrealized losses are related to an increase in market yields which may include increased risk-free interest rates and/or wider credit spreads since the time of initial purchase. Similarly, gross unrealized gains reflect a decrease in market yields since the time of initial purchase.

Capital Resources and Liquidity

Capital Resources and Liquidity

Capital resources consist of shareholders’ equity and debt, representing funds deployed or available to be deployed to support business operations or for general corporate purposes.

Capital resources
($ in millions)	March 31, 2018			December 31, 2017
Preferred stock, common stock, treasury stock, retained income and other shareholders’ equity items	$	24,427		$	22,245
Accumulated other comprehensive (loss) income	(1,150		)	306
Total shareholders’ equity	23,277			22,551

Ratio of debt to shareholders’ equity	29.4		%	28.2		%
Ratio of debt to capital resources	22.7		%	22.0		%

Shareholders’ equity increased in the first three months of 2018, primarily due to net income and issuance of preferred stock, partially offset by common share repurchases and dividends paid to shareholders. In the three months ended March 31, 2018, we paid dividends of $132 million and $29 million related to our common and preferred shares, respectively.

Preferred stock and debt issuances On March 29, 2018, we issued 23,000 shares of 5.625% Fixed Rate Noncumulative Perpetual Preferred Stock, Series G, for aggregate proceeds of $575 million, $250 million of Floating Rate Senior Notes due 2021 and $250 million Floating Rate Senior Notes due 2023. The proceeds of these issuances are for general corporate purposes, including the redemption, repayment or repurchase of certain preferred stock or debt.

Redemption of debt On April 13, 2018, we called for the redemption of our $224 million Series B 6.125% Fixed-to-Floating Rate Junior Subordinated Debentures (“Subordinated Debentures”). The Subordinated Debentures will be redeemed on May 13, 2018 at a redemption price equal to 100% of the outstanding principal of $224 million plus accrued and unpaid interest of $2 million.

Common share repurchases As of March 31, 2018, there was $935 million remaining on the $2.00 billion common share repurchase program that is expected to be completed by February 2019.

In December 2017, we entered into an accelerated share repurchase agreement (“ASR agreement”) with Morgan Stanley & Co. LLC to purchase $300 million of our outstanding common stock. This ASR agreement settled on January 5, 2018.

During the first three months of 2018, we repurchased 3.5 million common shares for $333 million in the market and under the ASR agreement.

Common shareholder dividends On January 2, 2018, we paid common shareholder dividends of $0.37. On February 7, 2018, we declared a common shareholder dividend of $0.46 payable on April 2, 2018.

Financial ratings and strength Our ratings are influenced by many factors including our operating and financial performance, asset quality, liquidity, asset/liability management, overall portfolio mix, financial

leverage (i.e., debt), exposure to risks such as catastrophes and the current level of operating leverage. Our preferred stock and subordinated debentures are viewed as having a common equity component by certain rating agencies and are given equity credit up to a pre-determined limit in our capital structure as determined by their respective methodologies. These respective methodologies consider the existence of certain terms and features in the instruments such as the noncumulative dividend feature in the preferred stock. In April 2018, A.M. Best upgraded The Allstate Corporation’s debt and short-term issuer ratings of a- and AMB-1 to a and AMB-1+, respectively, and affirmed the insurance financial strength ratings of A+ for Allstate Insurance Company (“AIC”), Allstate Life Insurance Company (“ALIC”) and Allstate Assurance Company. The outlook for the ratings is stable. There have been no changes to any of our ratings from S&P or Moody’s since December 31, 2017.

Liquidity sources and uses We actively manage our financial position and liquidity levels in light of changing market, economic, and business conditions. Liquidity is managed at both the entity and enterprise level across the Company, and is assessed on both base and stressed level liquidity needs. We believe we have sufficient liquidity to meet these needs. Additionally, we have existing intercompany agreements in place that facilitate liquidity management across the Company to enhance flexibility.

The Allstate Corporation is party to an Amended and Restated Intercompany Liquidity Agreement (“Liquidity Agreement”) with certain subsidiaries, which include, but are not limited to, ALIC and AIC. The Liquidity Agreement allows for short-term advances of funds to be made between parties for liquidity and other general corporate purposes. The Liquidity Agreement does not establish a commitment to advance funds on the part of any party. ALIC and AIC each serve as a lender and borrower, certain other subsidiaries serve only as borrowers, and the Corporation serves only as a lender. AIC also has a capital support agreement with ALIC. Under the capital support agreement, AIC is committed to providing capital to ALIC to maintain an adequate capital level. The maximum amount of potential

86www.allstate.com

Capital Resources and Liquidity

funding under each of these agreements is $1.00 billion.

In addition to the Liquidity Agreement, the Corporation also has an intercompany loan agreement with certain of its subsidiaries, which include, but are not limited to, AIC and ALIC. The amount of intercompany loans available to the Corporation’s subsidiaries is at the discretion of the Corporation. The maximum amount of loans the Corporation will have outstanding to all its eligible subsidiaries at any given point in time is limited to $1.00 billion. The Corporation may use commercial paper borrowings, bank lines of credit and securities lending to fund intercompany borrowings.

Parent company capital capacity At the parent holding company level, we have deployable assets totaling $3.86 billion as of March 31, 2018, comprising cash and investments that are generally saleable within one quarter. The substantial earnings capacity of the operating subsidiaries is the primary source of capital generation for the Corporation. This provides funds for the parent company’s fixed charges and other corporate purposes.

In the first three months of 2018, AIC paid dividends totaling $1.20 billion to its parent, Allstate Insurance Holdings, LLC (“AIH”), which then paid $1.20 billion of dividends to the Corporation.

Dividends may not be paid or declared on our common stock and shares of common stock may not be repurchased unless the full dividends for the latest completed dividend period on our preferred stock have been declared and paid or provided for. We are prohibited from declaring or paying dividends on our preferred stock if we fail to meet specified capital adequacy, net income or shareholders’ equity levels, except out of the net proceeds of common stock issued during the 90 days prior to the date of declaration. As of March 31, 2018, we satisfied all of the tests with no current restrictions on the payment of preferred stock dividends.

The terms of our outstanding subordinated debentures also prohibit us from declaring or paying any dividends or distributions on our common or preferred stock or redeeming, purchasing, acquiring, or making liquidation payments on our common stock or preferred stock if we have elected to defer interest payments on the subordinated debentures, subject to certain limited exceptions. In the first three months of 2018, we did not defer interest payments on the subordinated debentures.

Additional resources to support liquidity are as follows:

• The Corporation has access to a commercial paper facility with a borrowing limit of $1.00 billion to cover short-term cash needs. As of March 31, 2018, there were no balances outstanding and therefore the remaining borrowing capacity was $1.00 billion; however, the outstanding balance can fluctuate daily.

• The Corporation, AIC and ALIC have access to a $1.00 billion unsecured revolving credit facility that is available for short-term liquidity requirements. The maturity date of this facility is April 2021. The facility is fully subscribed among 11 lenders with the largest commitment being $115 million. The commitments of the lenders are several and no lender is responsible for any other lender’s commitment if such lender fails to make a loan under the facility. This facility contains an increase provision that would allow up to an additional $500 million of borrowing. This facility has a financial covenant requiring that we not exceed a 37.5% debt to capitalization ratio as defined in the agreement. This ratio was 15.6% as of March 31, 2018. Although the right to borrow under the facility is not subject to a minimum rating requirement, the costs of maintaining the facility and borrowing under it are based on the ratings of our senior unsecured, unguaranteed long-term debt. There were no borrowings under the credit facility during the first quarter of 2018.

• The Corporation has access to a universal shelf registration statement that was filed with the Securities and Exchange Commission (“SEC”) on April 30, 2018. We can use this shelf registration to issue an unspecified amount of debt securities, common stock (including 548 million shares of treasury stock as of March 31, 2018), preferred stock, depositary shares, warrants, stock purchase contracts, stock purchase units and securities of trust subsidiaries. The specific terms of any securities we issue under this registration statement will be provided in the applicable prospectus supplements.

⁽¹⁾  Includes $925 million of liabilities with a contractual surrender charge of less than 5% of the account balance.

⁽²⁾  $782 million of the contracts with market value adjusted surrenders have a 30-45 day period at the end of their initial and subsequent interest rate guarantee periods (which are typically 1, 5, 7 or 10 years) during which there is no surrender charge or market value adjustment.

⁽³⁾  89% of these contracts have a minimum interest crediting rate guarantee of 3% or higher.

⁽⁴⁾  Includes $722 million of contractholder funds on variable annuities reinsured to The Prudential Insurance Company of America, a subsidiary of Prudential Financial Inc., in 2006.

Retail life and annuity products may be surrendered by customers for a variety of reasons. Reasons unique to individual customers include a current or unexpected need for cash or a change in life insurance coverage needs. Other key factors that may impact the likelihood of customer surrender include the level of the contract surrender charge, the length of time the contract has been in force, distribution channel, market interest rates, equity market conditions and potential tax implications.

In addition, the propensity for retail life insurance policies to lapse is lower than it is for fixed annuities because of the need for the insured to be re-underwritten upon policy replacement. The annualized surrender and partial withdrawal rate on deferred fixed annuities and interest-sensitive life insurance products, based on the beginning of year contractholder funds, was 7.0% and 6.2% in the first quarter of 2018 and 2017, respectively. We strive to promptly pay customers who request cash surrenders; however, statutory regulations generally provide up to six months in most states to fulfill surrender requests.

Recent Developments

Recent Developments

The following updates the regulation disclosures included in Part I, Item 1. Regulation in our annual report on Form 10-K for the year-ended December 31, 2017.

Department of Labor. In March 2018, the U.S. Court of Appeals for the Fifth Circuit overturned the Department of Labor (“DOL”) Fiduciary Rule (“the Rule”). This ruling vacates the Rule in total, including those requirements, such as the impartial conduct standards, that became effective in June 2017. It is yet to be determined whether the DOL will file a petition for rehearing or appeal the decision. Barring any request for a rehearing or an appeal by the DOL, the Court’s ruling is expected to take effect in May 2018. Other state and federal regulators, such as the SEC, are considering implementation of impartial conduct or best interest standards. Such proposals, if effective, could impact products provided by Allstate agencies and Allstate’s broker-dealer, their sales processes, volumes, and producer compensation arrangements.

2013 EQUITY INCENTIVE PLAN

PERFORMANCE STOCK AWARD AGREEMENT

Further Terms and Conditions of Award. It is understood and agreed that the Award of PSAs evidenced by the PSA Award Agreement to which this is annexed is subject to the following additional terms and conditions:

1.    Termination of Employment, Death or Disability. Upon the Participant’s Termination of Employment, death or Disability, all unvested PSAs shall be treated as follows:

(A)    If the Participant dies or is determined to have a Disability, the number of PSAs that shall immediately vest shall be equal to the sum of:

(i)    the number of PSAs, if any, that have been earned based on the attainment of the performance goals set forth in Annex B, during such of the Performance Periods as have been completed on or prior to the Participant’s death or Disability; plus

(ii)    the Target Number of PSAs Granted for any incomplete Performance Periods in which the Participant’s death or Disability occurs and any Performance Periods that have not yet commenced by the date of the Participant’s death or Disability.

(B)    If the Participant’s Termination of Employment occurs twelve (12) months or more after the Date of Grant, and the Termination qualifies as Retirement at the Normal Retirement Date, then, except as provided in Section (D) below, the Award shall remain outstanding and the number of PSAs that vests, if any, will be determined in accordance with the terms hereof (including Annex B) in the same manner as if no Termination of Employment had occurred.

(C)    If the Participant’s Termination of Employment occurs within twelve (12) months of the Date of Grant, and the Termination qualifies as Retirement at the Normal Retirement Date, then, except as provided in Section (D) below, the Award shall remain outstanding and the number of PSAs that vests, if any, will be determined in accordance with the terms hereof (including Annex B) in the same manner as if no Termination of Employment had occurred, except that the Target Number of PSAs Granted shall be prorated (such proration to be determined by multiplying the Target Number of PSAs Granted by a fraction, the numerator of which is the number of days the Participant was employed since the Date of Grant and the denominator of which is 365). The remaining portion of the Award shall be forfeited as of the date of the Termination of Employment.

(D)    If the Participant’s Termination of Employment qualifies as Retirement at the Normal Retirement Date and the Participant dies after such Termination of Employment, but before the number of vested PSAs has been determined pursuant to Annex B, then the number of PSAs that shall immediately vest shall be equal to the sum of:

1

(i)    the number of PSAs, if any, that have been earned based on the attainment of the performance goals set forth in Annex B, during such of the Performance Periods as have been completed on or prior to the Participant’s death; plus

(ii)    the Target Number of PSAs Granted for any incomplete Performance Periods in which the Participant’s death occurs and any Performance Periods that have not yet commenced by the date of the Participant’s death.

(E)    If the Termination of Employment occurs during the Post-Change Period and

(i) the Participant’s Termination of Employment is initiated by the Employer other than for Cause, death, or Disability, or

(ii) the Participant is eligible to participate in The Allstate Corporation Change in Control Severance Plan (the “CIC Plan”) and the Participant’s Termination of Employment is initiated by the Participant for Good Reason,

then the number of PSAs, if any, that have been earned based on the attainment of the performance goals set forth in Annex B, during such of the Performance Periods as have been completed prior to the Change in Control, plus the number of PSAs as determined in accordance with Section 2, if any, shall vest as of the day prior to the Termination of Employment.

(F)    If the Participant’s Termination of Employment occurs prior to the Conversion Date for any other reason, then all PSAs shall be forfeited as of the date of such Termination of Employment.

2.    Impact of a Change in Control on the Performance Measure. Upon a Change in Control, the Committee will determine:

(A)the attainment of the performance goals set forth in Annex B, during such Performance Periods as have not been completed on the date of the Change of Control; and

(B) the number of PSAs which will vest in accordance with Section 1(E) and convert into shares of Stock following a Termination of Employment or on the Conversion Date following the end of all Performance Periods based on the attainment of the performance goals.

3.    Dividend Equivalent Right. Each PSA that vests in accordance with the PSA Award Agreement (including Annexes A and B) entitles a Participant to receive a cash Dividend Equivalent payment equal to the sum of all regular dividend payments that would have been made in respect of each share of Stock underlying such vested PSAs if the Participant were the holder of such shares during the period commencing on the Date of Grant and ending on the day prior to the Conversion Date (less applicable tax withholdings). Any Dividend Equivalents will be paid within 30 days of the Conversion Date of such PSAs.

For avoidance of doubt, Dividend Equivalents shall only be earned with respect to vested PSAs to the extent such PSAs were outstanding on the dividend record date of the dividend to which the Dividend Equivalent relates.

4.Non-Solicitation. While employed and for the one-year period starting on the date of Termination of Employment, any Participant who has received an Award under the Plan shall not, directly or indirectly:

(iii)    recover or cause to be recovered any cash paid or shares of Stock issued to the Participant in connection with any vesting, settlement, or exercise of an Award granted after May 19, 2009, if the vesting, settlement, or exercise occurred on or after the date that is one year prior to the date on which the Participant first violated any such the non-solicitation provisions.

5.    Non-Competition. Any Participant who has received an Award under the Plan on and after May 21, 2013, that remains subject to a Period of Restriction or other performance or vesting condition, shall not, for the one-year period following the date of Termination of Employment, directly or indirectly engage in, own or control an interest in, or act as principal, director, officer, or employee of, or consultant to, any firm or company that is a Competitive Business. “Competitive Business” is defined as a business that designs, develops, markets, or sells a product, product line, or service that competes with any product, product line, or service of the division in which Participant works.

6.    No Limitation on Other Rights; Blue Pencil.

If any of the covenants contained in Sections 4 and 5 or any part thereof, are held to be unenforceable, the court making such determination shall have the power to revise or modify such provision to make it enforceable to the maximum extent permitted by applicable law and, in its revised or modified form, said provision shall then be enforceable.

7.    Ratification of Actions. By accepting the PSA Award or other benefit under the Plan, the Participant and each person claiming under or through him shall be conclusively deemed to have indicated the Participant’s acceptance and ratification of, and consent to, any action taken under the Plan or the PSA Award by the Company, the Board, or the Committee.

8.    Notices. Any notice hereunder to the Company shall be addressed to its Stock Option Record Office and any notice hereunder to the Participant shall be addressed to the Participant at his or her most recent home address on file with the Company, subject to the right of either party to designate at any time hereafter in writing some other address.

9.    Governing Law and Severability. To the extent not preempted by Federal law, the PSA Award Agreement will be governed by and construed in accordance with the laws of the State of Delaware, without regard to conflicts of law provisions. In the event any provision of this PSA Award Agreement shall be held illegal or invalid for any reason, the illegality or invalidity shall not affect the remaining parts of this PSA Award Agreement, and this PSA Award Agreement shall be construed and enforced as if the illegal or invalid provision had not been included.

4

“Board Turnover” – see clause (c) of the definition of “Change in Control.”

“Cause” for those Participants who are not eligible to participate in the CIC Plan, means a Participant’s Termination of Employment for actions which would constitute conduct leading to immediate termination pursuant to Company policy. If a Participant is a participant in the CIC Plan, “Cause” means “Cause” as that term is defined in the CIC Plan on the Date of Grant.

“Change in Control” means, except as otherwise provided at the end of this definition, the occurrence of any one or more of the following:    

(a) (Voting Power) any Person or group (as such term is defined in Treasury Regulation Section 1.409A-3(i)(5)(v)(B)), other than a Subsidiary or any employee benefit plan (or any related trust) of the Company or any of its Subsidiaries, acquires or has acquired during the 12-month period ending on the date of the most recent acquisition by such Person or Persons, ownership of stock of the Company possessing 30% or more of the combined voting power of all Voting Securities of the Company (such a Person or group that is not a Similarly Owned Company (as defined below), a “More than 30% Owner”), except that no Change in Control shall be deemed to have occurred solely by reason of such ownership by a corporation with respect to which both more than 70% of the common stock of such corporation and Voting Securities representing more than 70% of the combined voting power of the Voting Securities of such corporation are then owned, directly or indirectly, by the Persons who were the direct or indirect owners of the common stock and Voting Securities of the Company immediately before such acquisition in substantially the same proportions as their ownership, immediately before such acquisition, of the common stock and Voting Securities of the Company, as the case may be (a “Similarly Owned Company”); or

(b) (Majority Ownership) any Person or group (as such term is defined in Treasury Regulation Section 1.409A-3(i)(5)(v)(B)), other than a Subsidiary or any employee benefit plan (or any related trust) of the Company or any of its Subsidiaries, acquires ownership of more than 50% of the voting power of all Voting Securities of the Company or of the total fair market value of the stock of the Company (such a Person or group that is not a Similarly Owned Company, a “Majority Owner”), except that no Change in Control shall be deemed to have occurred solely by reason of such ownership by a Similarly Owned Company; or

(c) (Board Composition) a majority of the members of the Board is replaced during any 12-month period by directors whose appointment or election is not endorsed by a majority of the members of the Board before the date of the appointment or election (“Board Turnover”); or

(d) (Reorganization) the consummation of a merger, reorganization, consolidation, or similar transaction, or of a plan or agreement for the sale or other disposition of all or substantially all of the consolidated assets of the Company, or a plan of liquidation of the Company (any of the foregoing, a “Reorganization Transaction”) that, does not qualify as an Exempt Reorganization Transaction.

Notwithstanding anything contained herein to the contrary: (i) no transaction or event shall constitute a Change in Control for purposes of this Agreement unless the transaction or event constituting the Change in Control also constitutes a change in the ownership of a corporation (as defined in Treasury Regulation Section 1.409A-3(i)(5)(v)), a change in effective control of a corporation (as defined in Treasury Regulation Section 1.409A-3(i)(5)(vi)) or a change in the ownership of a substantial portion of the assets of a corporation (as defined in Treasury Regulation Section 1.409A-3(i)(5)(vii)); and (ii) no sale or disposition of one or more Subsidiaries (“Sale

5

If any of the covenants contained in Sections 3 and 4 or any part thereof, are held to be unenforceable, the court making such determination shall have the power to revise or modify such provision to make it enforceable to the maximum extent permitted by applicable law and, in its revised or modified form, said provision shall then be enforceable.

6.    Transferability of Options. Except as set forth in this Section 6, the Option shall be exercisable during the Participant’s lifetime only by the Participant and may not be assigned or transferred other than by will or the laws of descent and distribution. The Option, to the extent vested, may be transferred by the Participant during his lifetime to any "Family Member." A transfer of the Option pursuant to this Section 6 may only be effected by the Company at the written request of a Participant and shall be effective only when recorded in the Company’s record of outstanding Options. Such transferred Option may not be subsequently transferred by the transferee except by will or the laws of descent and distribution. A transferred Option shall continue to be governed by and subject to the terms and limitations of the Plan and this Option Award Agreement, and the transferee shall be entitled to the same rights as the Participant, as if no transfer had taken place. In no event shall an Option be transferred for consideration.

In the event any provision of the Option Award Agreement shall be held illegal or invalid for any reason, the illegality or invalidity shall not affect the remaining parts of this Option Award Agreement, and this Option Award Agreement shall be construed and enforced as if the illegal or invalid provision had not been included.

"Board Turnover" – see clause (c) of the definition of “Change in Control.”

Notwithstanding anything contained herein to the contrary: (i) no transaction or event shall constitute a Change in Control for purposes of this Agreement unless the transaction or event constituting the Change in Control also constitutes a change in the ownership of a corporation (as defined in Treasury Regulation Section 1.409A-3(i)(5)(v)), a change in effective control of a corporation (as defined in Treasury Regulation Section 1.409A-3(i)(5)(vi)) or a change in the ownership of a substantial portion of the assets of a corporation (as defined in Treasury Regulation Section 1.409A-3(i)(5)(vii)); and (ii) no sale or disposition of one or more Subsidiaries (“Sale Subsidiary”) or the assets thereof shall constitute a Change in Control for purposes of this Agreement if the investments in and advances by the Company and its Subsidiaries (other than the Sale Subsidiaries) to such Sale Subsidiary as of immediately prior to the sale or disposition determined in accordance with Generally Accepted Accounting Principles (“GAAP”) (but after intercompany eliminations and net of the effect of intercompany reinsurance) are less than 51% of the Consolidated Total Shareholders’ Equity of the Company as of immediately prior to the sale or disposition. Consolidated Total Shareholders’ Equity means, at any date, the total shareholders’ equity of the Company and its Subsidiaries at such date, as reported in the consolidated financial statements prepared in accordance with GAAP.

“CIC Plan” – see subsection 2(D).

“Good Reason” means “Good Reason” as that term is defined in the CIC Plan on the Date of Grant.

"Gross Fair Market Value" means the value of the assets of the Company, or the value of the assets being disposed of, determined without regard to any liabilities associated with such assets.

The dividend equivalent payments will accrue during such period and will be paid within 30 days of the Conversion Date of such RSUs.

3

Dividend equivalent accruals shall be made only with respect to such RSUs that were outstanding on the applicable dividend record date.

8.    Ratification of Actions. By accepting the RSU Award or other benefit under the Plan, the Participant and each person claiming under or through him shall be conclusively deemed to have indicated the Participant's acceptance and ratification of, and consent to, any action taken under the Plan or the RSU Award by the Company, the Board, or the Compensation and Succession Committee.

9.    Notices. Any notice hereunder to the Company shall be addressed to its Stock Option Record Office and any notice hereunder to the Participant shall be addressed to the Participant at his or her most recent home address on file with the Company, subject to the right of either party to designate at any time hereafter in writing some other address.

10.    Governing Law and Severability. To the extent not preempted by Federal law, the RSU Award Agreement will be governed by and construed in accordance with the laws of the State of Delaware, without regard to conflicts of law provisions. In the event any provision of this RSU Award Agreement shall be held illegal or invalid for any reason, the illegality or invalidity shall not affect the remaining parts of this RSU Award Agreement, and this RSU Award Agreement shall be construed and enforced as if the illegal or invalid provision had not been included.

11.    Definitions. In addition to the following definitions, capitalized terms not otherwise defined herein shall have the meanings given them in the Plan.

"Board Turnover" – see clause (c) of the definition of "Change in Control."

"Cause" for those Participants who are not eligible to participate in the CIC Plan, means a Participant’s Termination of Employment for actions which would constitute conduct leading to immediate termination pursuant to Company policy. If a Participant is a participant in the CIC Plan, "Cause" means “Cause” as that term is defined in the CIC Plan on the Date of Grant.

"Change in Control" means, except as otherwise provided at the end of this definition, the occurrence of any one or more of the following:    

(a) (Voting Power) any Person or group (as such term is defined in Treasury Regulation Section 1.409A-3(i)(5)(v)(B)), other than a Subsidiary or any employee benefit plan (or any related trust) of the Company or any of its Subsidiaries, acquires or has acquired during the 12-month period ending on the date of the most recent acquisition by such Person or Persons, ownership of stock of the Company possessing 30% or more of the combined voting power of all Voting Securities of the Company (such a Person or group that is not a Similarly Owned Company (as defined below), a "More than 30% Owner"), except that no Change in Control shall be deemed to have occurred solely by reason of such ownership by a corporation with respect to which both more than 70% of the common stock of such corporation and Voting Securities representing more than 70% of the combined voting power of the Voting Securities of such corporation are then owned, directly or indirectly, by the Persons who were the direct or indirect owners of the common stock and Voting Securities of the Company immediately before such acquisition in substantially the same proportions as their ownership, immediately before such acquisition, of the common stock and Voting Securities of the Company, as the case may be (a "Similarly Owned Company"); or

(b) (Majority Ownership) any Person or group (as such term is defined in Treasury Regulation Section 1.409A-3(i)(5)(v)(B)), other than a Subsidiary or any employee benefit plan (or any related trust) of the Company or any of its Subsidiaries, acquires ownership of

4

more than 50% of the voting power of all Voting Securities of the Company or of the total fair market value of the stock of the Company (such a Person or group that is not a Similarly Owned Company, a "Majority Owner"), except that no Change in Control shall be deemed to have occurred solely by reason of such ownership by a Similarly Owned Company; or

(c) (Board Composition) a majority of the members of the Board is replaced during any 12-month period by directors whose appointment or election is not endorsed by a majority of the members of the Board before the date of the appointment or election ("Board Turnover"); or

(d) (Reorganization) the consummation of a merger, reorganization, consolidation, or similar transaction, or of a plan or agreement for the sale or other disposition of all or substantially all of the consolidated assets of the Company, or a plan of liquidation of the Company (any of the foregoing, a "Reorganization Transaction") that, does not qualify as an Exempt Reorganization Transaction.

Notwithstanding anything contained herein to the contrary: (i) no transaction or event shall constitute a Change in Control for purposes of this Agreement unless the transaction or event constituting the Change in Control also constitutes a change in the ownership of a corporation (as defined in Treasury Regulation Section 1.409A-3(i)(5)(v)), a change in effective control of a corporation (as defined in Treasury Regulation Section 1.409A-3(i)(5)(vi)) or a change in the ownership of a substantial portion of the assets of a corporation (as defined in Treasury Regulation Section 1.409A-3(i)(5)(vii)); and (ii) no sale or disposition of one or more Subsidiaries ("Sale Subsidiary") or the assets thereof shall constitute a Change in Control for purposes of this Agreement if the investments in and advances by the Company and its Subsidiaries (other than the Sale Subsidiaries) to such Sale Subsidiary as of immediately prior to the sale or disposition determined in accordance with Generally Accepted Accounting Principles ("GAAP") (but after intercompany eliminations and net of the effect of intercompany reinsurance) are less than 51% of the Consolidated Total Shareholders’ Equity of the Company as of immediately prior to the sale or disposition. Consolidated Total Shareholders’ Equity means, at any date, the total shareholders’ equity of the Company and its Subsidiaries at such date, as reported in the consolidated financial statements prepared in accordance with GAAP.

"Exempt Reorganization Transaction" means a Reorganization Transaction that fails to result in (a) any Person or group (as such term is defined in Treasury Regulation Section 1.409A-3(i)(5)(v)(B)) becoming a More than 30% Owner or a Majority Owner, (b) Board Turnover, or (c) a sale or disposition to any Person or group (as such term is defined in Treasury Regulation Section 1.409A-3(i)(5)(v)(B)) of the assets of the Company that have a total Gross Fair Market Value (as defined below) equal to at least forty percent (40%) of the total Gross Fair Market Value of all of the assets of the Company immediately before such transaction.

“CIC Plan” – see subsection 2(D).

"Good Reason" means “Good Reason” as that term is defined in the CIC Plan on the Date of Grant.

"Gross Fair Market Value" means the value of the assets of the Company, or the value of the assets being disposed of, determined without regard to any liabilities associated with such assets.

"Majority Owner" – see clause (b) of the definition of "Change in Control."

5

"More than 30% Owner" – see clause (a) of the definition of "Change in Control."

"Post-Change Period" means the period commencing on the date on which a Change in Control first occurs and ending on the second anniversary of the date on which a Change in Control first occurs.

"Reorganization Transaction" – see clause (d) of the definition of "Change in Control."

"Similarly Owned Company" -- see clause (a) of the definition of "Change in Control."

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.

Adopted accounting standards

Recognition and Measurement of Financial Assets and Financial Liabilities

Effective January 1, 2018, the Company adopted new Financial Accounting Standards Board (“FASB”) guidance requiring equity investments, including equity securities and limited partnership interests not accounted for under the equity method of accounting or that do not result in consolidation to be measured at fair value with changes in fair value recognized in net income. The guidance clarifies that an entity should evaluate the realizability of deferred tax assets related to available-for-sale fixed income securities in combination with the entity’s other deferred tax assets. The Company’s adoption of the new FASB guidance included adoption of the relevant elements of Technical Corrections and Improvements to Financial Instruments, issued in February 2018.

Upon adoption of the new guidance on January 1, 2018, $1.16 billion of pre-tax unrealized net capital gains for equity securities were reclassified from AOCI to retained income. The after-tax change in accounting for equity securities did not affect the Company’s total shareholders’ equity and the unrealized net capital gains reclassified to retained income will never be recognized in net income.

Upon adoption of the new guidance on January 1, 2018, the carrying value of cost method limited partnership interests increased $224 million, pre-tax to fair value. The after-tax cumulative-effect increase in retained income of $177 million increased the Company’s shareholders’ equity but will never be recognized in net income thereby negatively impacting calculations of returns on equity.

Revenue from Contracts with Customers

Effective January 1, 2018, the Company adopted new FASB guidance which revises the criteria for revenue recognition. Insurance contracts are excluded from the scope of the new guidance. The Company’s principal activities impacted by the new guidance are those related to the issuance of protection plans for consumer products and automobiles and service contracts that provide roadside assistance. Under the guidance, the transaction price is attributed to underlying performance obligations in the contract and revenue is recognized as the entity satisfies performance obligations and transfers control of a good or service to the customer. Incremental costs of obtaining a contract may be capitalized to the extent the entity expects to recover those costs.

Adoption of the guidance on January 1, 2018 under the modified retrospective approach resulted in the recognition of an immaterial after-tax net cumulative effect increase to the beginning balance of retained income. In addition to the net cumulative effect, the Company also recorded in the statement of financial position an increase of approximately $160 million pre-tax in unearned premiums with a corresponding $160 million pre-tax increase in DAC for protection plans sold directly to retailers for which SquareTrade is deemed to be the principal in the transaction. These impacts offset fully and did not impact retained income at the date of adoption.

Presentation of Net Periodic Pension and Postretirement Benefits Costs

Effective January 1, 2018, the Company adopted new FASB guidance requiring identification, on the statement of operations or in disclosures, the line items in which the components of net periodic pension and postretirement benefits costs are presented. The new guidance permits only the service cost component to be eligible for capitalization where applicable. The adoption had no impact on the Company’s results of operations or financial position.

Goodwill Impairment

In January 2017, the FASB issued guidance to simplify the accounting for goodwill impairment which removes the second step of the goodwill impairment test that requires a hypothetical purchase price allocation. Under the new guidance, goodwill impairment will be measured and recognized as the amount by which a reporting unit’s carrying value, including goodwill, exceeds its fair value, not to exceed the carrying amount of goodwill allocated to the reporting unit. The revised guidance does not affect a reporting entity’s ability to first assess qualitative factors by reporting unit to determine whether to perform the quantitative goodwill impairment test. The guidance is to be applied on a prospective basis, with the effects, if any, recognized in net income in the period of adoption. The Company elected to early adopt the new guidance as of January 1, 2018. The adoption had no impact on the Company’s results of operations or financial position.

Changes to significant accounting policies

Investments

Changes were made to the Company’s Significant Accounting Policies upon adoption of new FASB guidance related to the recognition and measurement of financial assets. Equity securities primarily include common stocks, exchange traded and mutual funds, non-redeemable preferred stocks and real estate investment trust equity investments. Equity securities are carried at fair value. Equity securities without readily determinable or estimable fair values are measured using the measurement alternative which is cost less impairment, if any, and adjustments resulting from observable price changes in orderly transactions for the identical or similar investment of the same issuer. The periodic change in fair value of equity securities is recognized within realized capital gains and losses on the Condensed Consolidated Statements of Operations effective January 1, 2018.

Investments in limited partnership interests include interests in private equity funds, real estate funds and other funds. Where the Company’s interest is so minor that it exercises virtually no influence over operating and financial policies, investments in limited partnership interests purchased prior to January 1, 2018 are accounted for at fair value primarily utilizing the net asset value as a practical expedient (“NAV”) to determine fair value. All other investments in limited partnership interests, including those purchased subsequent to January 1, 2018, are accounted for in accordance with the equity method of accounting (“EMA”).

Investment income from limited partnership interests carried at fair value is recognized based upon the changes in fair value of the investee’s equity primarily determined using NAV. Income from EMA limited partnership interests is recognized based on the Company’s share of the partnerships’ earnings. Income from EMA limited partnership interests is generally recognized on a three month delay due to the availability of the related financial statements.

Recognition of Revenue

Revenues related to protection plans, other contracts (primarily finance and insurance products) and roadside assistance are deferred and earned over the term of the contract in a manner that recognizes revenue as obligations under the contracts are performed. Revenues from these products are classified as premiums as the products are backed by insurance. Protection plans and finance and insurance premiums are recognized using a cost-based incurrence method. Roadside assistance premiums are recognized evenly over the term of the contract as performance obligations are fulfilled.

Tax Reform

On December 22, 2017, Public Law 115-97, known as the Tax Cuts and Jobs Act of 2017 (“Tax Legislation”) became effective, permanently reducing the U.S. corporate income tax rate from 35% to 21% beginning January 1, 2018. As a result, the corporate tax rate is not comparable between periods.

Pending accounting standards

Accounting for Leases

In February 2016, the FASB issued guidance revising the accounting for leases. Under the new guidance, lessees will be required to recognize a right-of-use asset and lease liability for all leases other than those that meet the definition of a short-term lease. The lease liability will be equal to the present value of lease payments. A right-of-use asset will be based on the lease liability adjusted for qualifying initial direct costs. Recognition of the lease liability and right-of-use asset will result in an increase in total assets and liabilities in the Condensed Consolidated Statement of Financial Position. The expense of operating leases under the new guidance will be recognized in the income statement on a straight-line basis by adjusting the amortization of the right-of-use asset to produce a straight-line expense when combined with the interest expense on the lease liability. For finance leases, the expense components are computed separately and produce greater up-front expense compared to operating leases as interest expense on the lease liability is higher in early years and the right-of-use asset is amortized on a straight-line basis. Lease classification will be based on criteria similar to those currently applied. The accounting model for lessors will be similar to the current model with modifications to reflect definition changes for components such as initial direct costs. Lessors will continue to classify leases as operating, direct financing, or sales-type. The guidance is effective for reporting periods beginning after December 15, 2018, using a modified retrospective approach applied at the beginning of the earliest period presented. The FASB has exposed for comment an optional simplified transition approach that would allow application of the transition provisions at the effective date instead of the earliest date presented. The Company is in the process of evaluating the impact of adoption, which is not expected to be material to the Company’s results of operations or financial position.

Measurement of Credit Losses on Financial Instruments

In June 2016, the FASB issued guidance which revises the credit loss recognition criteria for certain financial assets measured at amortized cost, including reinsurance recoverables. The new guidance replaces the existing incurred loss recognition model with an expected loss recognition model. The objective of the expected credit loss model is for the reporting entity to recognize its estimate of expected credit losses for affected financial assets in a valuation allowance deducted from the amortized cost basis of the related financial assets that results in presenting the net carrying value of the financial assets at the amount expected to be collected. The reporting entity must consider all relevant information available when estimating expected credit losses, including details about past events, current conditions, and reasonable and supportable forecasts over the life of an asset. Financial assets may be evaluated individually or on a pooled basis when they share similar risk characteristics. The measurement of credit losses for available-for-sale debt securities measured at fair value is not affected except that credit losses recognized are limited to the amount by which fair value is below amortized cost and the carrying value adjustment is recognized through a valuation allowance and not as a direct write-down. The guidance is effective for reporting periods beginning after December 15, 2019, and for most affected instruments must be adopted using a modified retrospective approach, with a cumulative effect adjustment recorded to beginning retained income. The Company is in the process of evaluating the impact of adoption.

Accounting for Hedging Activities

In August 2017, the FASB issued amendments intended to better align hedge accounting with an organization’s risk management activities. The amendments expand hedge accounting for nonfinancial and financial risk components and revise the measurement methodologies to better align with an organization’s risk management activities. Separate presentation of hedge ineffectiveness is eliminated to provide greater transparency of the full impact of hedging by requiring presentation of the results of the hedged item and hedging instrument in a single financial statement line item. In addition, the amendments reduce complexity by simplifying the manner in which assessments of hedge effectiveness may be performed. The guidance is effective for reporting periods beginning after December 15, 2018. The presentation and disclosure guidance is effective on a prospective basis. The impact of adoption is not expected to be material to the Company’s results of operations or financial position.

Other revenue presentation

Concurrent with the adoption of new FASB guidance on revenue from contracts with customers and the Company’s objective of providing more information related to revenues for our Services Businesses, the Company revised the presentation of total revenue to include other revenue. Previously, components of other revenue were presented within operating costs and expenses and primarily represent fees collected from policyholders relating to premium installment payments, commissions on sales of non-proprietary products, fee-based services and other revenue transactions. Other revenue is recognized when performance obligations are fulfilled. Prior periods have been reclassified to conform to current separate presentation of other revenue.

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 and 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.

Options to purchase 1.0 million and 2.8 million Allstate common shares, with exercise prices ranging from $86.61 to $102.84 and $67.81 to $81.86, were outstanding for the three-month periods ended March 31, 2018 and 2017, respectively, but were not included in the computation of diluted earnings per common share in those periods.

Acquisition

Note 3 Acquisition

On January 3, 2017, the Company acquired SquareTrade Holding Company, Inc. (“SquareTrade”), a consumer product protection plan provider that distributes through many of America’s major retailers and Europe’s mobile operators, for $1.4 billion in cash. SquareTrade is a provider of consumer electronics and appliance protection plans covering products including TVs, smartphones and computers. This acquisition broadens Allstate’s unique product offerings to better meet consumers’ needs.

In connection with the acquisition, the Company recorded goodwill of $1.10 billion, commissions paid to retailers (reported in deferred policy acquisition costs) of $66 million, other intangible assets (reported in other assets) of $555 million, contractual liability insurance policy premium expenses (reported in other assets) of $205 million, unearned premiums of $389 million and net deferred income tax liability of $138 million. These amounts reflect re-measurement adjustments to the fair value of the opening balance sheet assets and liabilities.

Of the $555 million assigned to other intangible assets, $465 million is attributable to acquired customer relationships. The $555 million assigned to other intangible assets also included $69 million assigned to the SquareTrade trade name which is considered to have an indefinite useful life. The amortization expense of intangible assets for the three months ended March 31, 2018 and 2017 was $21 million and $23 million, respectively.

The Company uses its best estimate of future cash flows expected to be collected from the fixed income security, discounted at the security’s original or current effective rate, as appropriate, to calculate a recovery value and determine whether a credit loss exists. 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, including past events, current conditions, and reasonable and supportable assumptions and forecasts, are 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, foreign exchange rates, the financial condition and future earnings potential of the issue or issuer, expected defaults, expected recoveries, the value of underlying collateral, vintage, 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, sector 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 estimated recovery value is less than the amortized cost of the security, a credit loss exists and an OTTI for the difference between the estimated recovery value and amortized cost is recorded in earnings. 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.

⁽³⁾  The insurance reserves adjustment represents the amount by which the reserve balance would increase if the net unrealized gains in the applicable product portfolios were realized and reinvested at current lower interest rates, resulting in a premium deficiency. This adjustment primarily relates to structured settlement annuities with life contingencies (a type of immediate fixed annuities).

⁽⁴⁾  The DAC and DSI adjustment balance represents the amount by which the amortization of DAC and DSI would increase or decrease if the unrealized gains or losses in the respective product portfolios were realized.

Portfolio monitoring

The Company has a comprehensive portfolio monitoring process to identify and evaluate each fixed income security whose carrying value may be other-than-temporarily impaired.

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, the security’s decline in fair value is considered other than temporary and is 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 by discounting the best estimate of future cash flows at the security’s original or current effective rate, as appropriate, and compares this to the amortized cost of the security. If the Company does not expect to receive cash flows sufficient to recover the entire amortized cost basis of the fixed income security, the credit loss component of the impairment is recorded in earnings, with the remaining amount of the unrealized loss related to other factors recognized in other comprehensive income.

For fixed income securities managed by third parties, either the Company has contractually retained its decision-making authority as it pertains to selling securities that are in an unrealized loss position or it recognizes any unrealized loss at the end of the period through a charge to earnings.

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 established thresholds. The process also includes the monitoring of other impairment 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 OTTI using all reasonably available information relevant to the collectability or recovery of the security. Inherent in the Company’s evaluation of OTTI 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 is other than temporary 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 length of time and extent to which the fair value has been less than amortized cost.

As of March 31, 2018, $721 million of the $745 million unrealized losses are related to securities with an unrealized loss position less than 20% of amortized cost, the degree of which suggests that these securities do not pose a high risk of being other-than-temporarily impaired. Of the $721 million, $611 million are related to unrealized losses on investment grade fixed income securities. Of the remaining $110 million, $92 million have been in an unrealized loss position for less than 12 months. Investment grade is defined as a security having a rating of Aaa, Aa, A or Baa from Moody’s, a rating of AAA, AA, A or BBB from S&P Global Ratings (“S&P”), a comparable rating from another nationally recognized rating agency, 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 and/or wider credit spreads since the time of initial purchase.

As of March 31, 2018, the remaining $24 million of unrealized losses are related to securities in unrealized loss positions greater than or equal to 20% of amortized cost. Investment grade fixed income securities comprising $12 million of these unrealized losses were 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. Of the $24 million, $12 million are related to below investment grade fixed income securities. Of these amounts, $4 million are related to below investment grade fixed income securities that had been in an unrealized loss position greater than or equal to 20% of amortized cost for a period of twelve or more consecutive months as of March 31, 2018.

ABS, RMBS and CMBS 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, 2018, 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.

Limited partnerships

Investments in limited partnership interests include interests in private equity funds, real estate funds and other funds. As of March 31, 2018 and December 31, 2017, the carrying value of EMA limited partnerships totaled $5.77 billion and $5.41 billion, respectively, and limited partnerships carried at fair value as of March 31, 2018, while at cost method as of December 31, 2017, totaled $1.66 billion and $1.33 billion, respectively.

Mortgage loans

Mortgage loans are evaluated for impairment on a specific loan basis through a quarterly credit monitoring process and review of key credit quality indicators. Mortgage loans are considered impaired when it is probable that the Company will not collect the contractual principal and interest. Valuation allowances are established for impaired loans to reduce the carrying value to the fair value of the collateral less costs to sell or the present value of the loan’s expected future repayment cash flows discounted at the loan’s original effective interest rate. Impaired mortgage loans may not have a valuation allowance when the fair value of the collateral less costs to sell is higher than the carrying value. Valuation allowances are adjusted for subsequent changes in the fair value of the collateral less costs to sell or present value of the loan’s expected future repayment cash flows. Mortgage loans are charged off against their corresponding valuation allowances when there is no reasonable expectation of recovery. The impairment evaluation is non-statistical in respect to the aggregate portfolio but considers facts and circumstances attributable to each loan. It is not considered probable that additional impairment losses, beyond those identified on a specific loan basis, have been incurred as of March 31, 2018.

Accrual of income is suspended for mortgage loans that are in default or when full and timely collection of principal and interest payments is not probable. Cash receipts on mortgage loans on nonaccrual status are generally recorded as a reduction of carrying value.

Debt service coverage ratio is considered a key credit quality indicator when mortgage loans are evaluated for impairment. Debt service coverage ratio represents the amount of estimated cash flows from the property available to the borrower to meet principal and interest payment obligations. Debt service coverage ratio estimates are updated annually or more frequently if conditions are warranted based on the Company’s credit monitoring process.

Mortgage loans with a debt service coverage ratio below 1.0 that are not considered impaired primarily relate to instances where the borrower has the financial capacity to fund the revenue shortfalls from the properties for the foreseeable term, the decrease in cash flows from the properties is considered temporary, or there are other risk mitigating circumstances such as additional collateral, escrow balances or borrower guarantees.

Payments on all mortgage loans were current as of March 31, 2018 and December 31, 2017.

Short-term investments

Short-term investments, including commercial paper, U.S. Treasury bills, money market funds and other short-term investments, are carried at fair value. As of March 31, 2018 and December 31, 2017, the fair value of short-term investments totaled $3.42 billion and $1.94 billion, respectively.

Other investments

Other investments primarily consist of bank loans, policy loans, agent loans, real estate and derivatives. Bank loans are primarily senior secured corporate loans and are carried at amortized cost. Policy loans are carried at unpaid principal balances. Agent loans are loans issued to exclusive Allstate agents and are carried at unpaid principal balances, net of valuation allowances and unamortized deferred fees or costs. Real estate is carried at cost less accumulated depreciation. Derivatives are carried at fair value.

Fair Value Disclosures [Abstract]

Fair Value of Assets and Liabilities

Note 6 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. The first is where 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. The second situation where the Company classifies securities in Level 3 is where 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 investments such as mortgage loans, bank loans, agent loans and policy loans. Accordingly, such investments are only included in the fair value hierarchy disclosure when the investment is subject to remeasurement at fair value after initial recognition and the resulting remeasurement is reflected in the condensed consolidated financial statements.

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 valuation techniques for assets and liabilities measured at fair value on a recurring basis

Level 1 measurements

• Fixed income securities: Comprise certain U.S. Treasury fixed income securities. Valuation is based on unadjusted quoted prices for identical assets in active markets that the Company can access.

• Equity securities: Comprise actively traded, exchange-listed equity securities. Valuation is based on unadjusted quoted prices for identical assets in active markets that the Company can access.

• Short-term: Comprise U.S. Treasury bills valued based on unadjusted quoted prices for identical assets in active markets that the Company can access and actively traded money market funds that have daily quoted net asset values for identical assets that the Company can access.

• Separate account assets: Comprise actively traded mutual funds that have daily quoted net asset values that are readily determinable for identical assets that the Company can access. Net asset values for the actively traded mutual funds in which the separate account assets are invested are obtained daily from the fund managers.

Level 2 measurements

• Fixed income securities:

U.S. government and agencies: 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.

Municipal: 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 - public: 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: 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.

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.

ABS - collateralized debt obligations (“CDO”) and ABS - consumer and other: 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, prepayment speeds, collateral performance and credit spreads. Certain ABS - CDO and ABS - consumer and other are valued based on non-binding broker quotes whose inputs have been corroborated to be market observable.

RMBS: 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, prepayment speeds, collateral performance and credit spreads.

CMBS: 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.

Redeemable preferred stock: 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, underlying stock prices and credit spreads.

• 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. For certain short-term investments, amortized cost is used as the best estimate of fair value.

• 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, 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, 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 in markets that exhibit less liquidity relative to those markets supporting Level 2 fair value measurements, 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 Corporate - privately placed: Primarily valued based on non-binding broker quotes where the inputs have not been corroborated to be market observable. Other inputs 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.

ABS - CDO, ABS - consumer and other, RMBS and CMBS: Valued based on non-binding broker quotes received from brokers who are familiar with the investments and where the inputs have not been corroborated to be market observable.

• Equity securities: The primary inputs to the valuation include quoted prices or quoted net asset values for identical or similar assets in markets that exhibit less liquidity relative to those markets supporting Level 2 fair value measurements.

• 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.

• Contractholder funds: Derivatives embedded in certain life and annuity contracts are valued internally using models widely accepted in the financial services industry that determine a single best estimate of fair value for the embedded derivatives within a block of contractholder liabilities. The models primarily use stochastically determined cash flows based on the contractual elements of embedded derivatives, projected option cost and applicable market data, such as interest rate yield curves and equity index volatility assumptions. These are categorized as Level 3 as a result of the significance of non-market observable inputs.

Assets and liabilities measured at fair value on a non-recurring basis

Mortgage loans written-down to fair value in connection with recognizing impairments are valued based on the fair value of the underlying collateral less costs to sell. EMA limited partnership interests written-down to fair value in connection with recognizing OTTI losses are generally valued using net asset values.

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. We receive distributions of income and from liquidation of the underlying assets of the investees over the life of these investments, typically 10-12 years. As of March 31, 2018, the Company has commitments to invest $943 million in limited partnership interests valued using NAV.

Derivatives embedded in life and annuity contracts – Equity-indexed and forward starting options	$	(252	)	Stochastic cash flow model	Projected option cost	1.0 - 2.2%	1.74%

The embedded derivatives are equity-indexed and forward starting options in certain life and annuity products that provide customers with interest crediting rates based on the performance of the S&P 500. If the projected option cost increased (decreased), it would result in a higher (lower) liability fair value.

As of March 31, 2018 and December 31, 2017, Level 3 fair value measurements of fixed income securities total $487 million and $606 million, respectively, and include $278 million and $271 million, respectively, of securities valued based on non-binding broker quotes where the inputs have not been corroborated to be market observable and $54 million and $58 million, respectively, of municipal fixed income securities that are not rated by third party credit rating agencies.  The Company does not develop the unobservable inputs used in measuring fair value; therefore, these 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.

Transfers between level categorizations may occur due to changes in the availability of market observable inputs, which generally are caused by changes in market conditions such as liquidity, trading volume or bid-ask spreads. Transfers between level categorizations may also occur due to changes in the valuation source. Transfers in and out of level categorizations are reported as having occurred at the beginning of the quarter in which the transfer occurred. Therefore, for all transfers into Level 3, all realized and changes in unrealized gains and losses in the quarter of transfer are reflected in the Level 3 rollforward table.

There were no transfers between Level 1 and Level 2 during the three months ended March 31, 2018 or 2017.

Transfers into Level 3 during the three months ended March 31, 2018 and 2017 included situations where a fair value quote was not provided by the Company’s independent third-party valuation service provider and as a result the price was stale or had been replaced with a broker quote where the inputs had not been corroborated to be market observable resulting in the security being classified as Level 3. Transfers out of Level 3 during the three months ended March 31, 2018 and 2017 included situations where a broker quote was used in the prior period and a fair value quote became available from the Company’s independent third-party valuation service provider in the current period. A quote utilizing the new pricing source was not available as of the prior period, and any gains or losses related to the change in valuation source for individual securities were not significant.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

Note 7 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 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 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. Credit default swaps are typically used to mitigate the credit risk within the Property-Liability fixed income portfolio. Equity index 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.

The Company utilizes several derivative strategies to manage risk in Allstate Life and Allstate Annuities. Asset-liability management is a risk management strategy that is principally employed by Allstate Life and Allstate Annuities to balance the respective interest-rate sensitivities of its assets and liabilities. Depending upon the attributes of the assets acquired and liabilities issued, derivative instruments such as interest rate swaps, caps, swaptions and futures are utilized to change the interest rate characteristics of existing assets and liabilities to ensure the relationship is maintained within specified ranges and to reduce exposure to rising or falling interest rates. Credit default swaps are typically used to mitigate the credit risk within the Allstate Life and Allstate Annuities fixed income portfolios. Futures and options are used for hedging the equity exposure contained in equity indexed life and annuity product contracts that offer equity returns to contractholders. In addition, the Company uses equity index futures to offset valuation losses in the equity portfolio during periods of declining equity market values. Foreign currency swaps and forwards are primarily used to reduce the foreign currency risk associated with holding foreign currency denominated investments.

The Company also has derivatives embedded in non-derivative host contracts that are 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. The Company’s primary embedded derivatives are equity options in life and annuity product contracts, which provide equity returns to contractholders.

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 Company designates certain investment risk transfer reinsurance agreements as fair value hedges when the hedging instrument is highly effective in offsetting the risk of changes in the fair value of the hedged item. The Company designates certain of its foreign currency swap contracts as cash flow hedges when the hedging instrument is highly effective in offsetting the exposure of variations in cash flows for the hedged risk that could affect net income. Amounts are reclassified to net investment income or realized capital gains and losses as the hedged item affects net income.

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 for fair value hedge accounting, net income includes the changes in the fair value of both the derivative instrument and the hedged risk, and therefore reflects any hedging ineffectiveness. 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.

For the three months ended March 31, 2018 and 2017, the Company had no derivatives used in fair value hedging relationships.

The Company manages its exposure to credit risk by utilizing highly rated counterparties, establishing risk control limits, executing legally enforceable master netting agreements (“MNAs”) and obtaining collateral where appropriate. 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. As of March 31, 2018, counterparties pledged $8 million in cash to the Company, and the Company pledged $21 million in cash and securities to counterparties which includes $4 million of collateral posted under MNAs for contracts containing credit-risk-contingent provisions that are in a liability position and $17 million of collateral posted under MNAs for contracts without credit-risk-contingent features. 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.

For certain exchange traded and cleared derivatives, margin deposits are required as well as daily cash settlements of margin accounts. As of March 31, 2018, the Company pledged $15 million in the form of margin deposits.

Market risk is the risk that the Company will incur losses due to adverse changes in market rates and prices. 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 instruments contain credit-risk-contingent termination events, cross-default provisions and credit support annex agreements. Credit-risk-contingent termination events allow the counterparties to terminate the derivative agreement or a specific trade on certain dates if AIC’s, ALIC’s or Allstate Life Insurance Company of New York’s (“ALNY”) 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. Credit-risk-contingent credit support annex agreements specify the amount of collateral the Company must post to counterparties based on AIC’s, ALIC’s or ALNY’s financial strength credit ratings by Moody’s or S&P, or in the event AIC, ALIC or ALNY are no longer rated by either Moody’s or S&P.

The following summarizes the fair value of derivative instruments with termination, cross-default or collateral credit-risk-contingent features that are in a liability position, as well as the fair value of assets and collateral that are netted against the liability in accordance with provisions within legally enforceable MNAs.

Credit derivatives - selling protection

A credit default swap (“CDS”) is a derivative instrument, representing an agreement between two parties to exchange the credit risk of a specified entity (or a group of entities), or an index based on the credit risk of a group of entities (all commonly referred to as the “reference entity” or a portfolio of “reference entities”), in return for a periodic premium. In selling protection, CDS are used to replicate fixed income securities and to complement the cash market when credit exposure to certain issuers is not available or when the derivative alternative is less expensive than the cash market alternative. CDS typically have a five-year term.

In selling protection with CDS, the Company sells credit protection on an identified single name, a basket of names in a first-to-default (“FTD”) structure or credit derivative index (“CDX”) that is generally investment grade, and in return receives periodic premiums through expiration or termination of the agreement. With single name CDS, this premium or credit spread generally corresponds to the difference between the yield on the reference entity’s public fixed maturity cash instruments and swap rates at the time the agreement is executed. With a FTD basket, because of the additional credit risk inherent in a basket of named reference entities, the premium generally corresponds to a high proportion of the sum of the credit spreads of the names in the basket and the correlation between the names. CDX is utilized to take a position on multiple (generally 125) reference entities. Credit events are typically defined as bankruptcy, failure to pay, or restructuring, depending on the nature of the reference entities. If a credit event occurs, the Company settles with the counterparty, either through physical settlement or cash settlement. In a physical settlement, a reference asset is delivered by the buyer of protection to the Company, in exchange for cash payment at par, whereas in a cash settlement, the Company pays the difference between par and the prescribed value of the reference asset. When a credit event occurs in a single name or FTD basket (for FTD, the first credit event occurring for any one name in the basket), the contract terminates at the time of settlement. For CDX, the reference entity’s name incurring the credit event is removed from the index while the contract continues until expiration. The maximum payout on a CDS is the contract notional amount. A physical settlement may afford the Company with recovery rights as the new owner of the asset.

The Company monitors risk associated with credit derivatives through individual name credit limits at both a credit derivative and a combined cash instrument/credit derivative level. The ratings of individual names for which protection has been sold are also monitored.

Reserve for Property-Liability Insurance Claims and Claims Expense [Abstract]

Reserve for Property-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. In the normal course of business, 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 incurred but not reported (“IBNR”) losses, the establishment of appropriate reserves, including reserves for catastrophes and reserves and reinsurance recoverables for the Discontinued Lines and Coverages, 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 current reporting period as it contains the greatest proportion of losses that have not been reported or settled. 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 prior year 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 reinsurance 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, technology, laws and regulations.

Allstate’s reserves for asbestos claims were $866 million and $884 million, net of reinsurance recoverables of $399 million and $412 million, as of March 31, 2018 and December 31, 2017, respectively. Reserves for environmental claims were $162 million and $166 million, net of reinsurance recoverables of $33 million and $33 million, as of March 31, 2018 and December 31, 2017, respectively.

Incurred claims and claims expense represents the sum of paid losses and reserve changes in the period. This expense includes losses from catastrophes of $361 million and $781 million in the three months ended March 31, 2018 and 2017, respectively, net of reinsurance and other recoveries. Catastrophes are an inherent risk of the property and casualty insurance business that have contributed to, and will continue to contribute to, material year-to-year fluctuations in the Company’s results of operations and financial position. During the three months ended March 31, 2018, incurred claims and claims expense included $51 million of prior year reserve reestimates, increasing net income. Prior year reserve reestimates excluding catastrophes is comprised of net decreases in auto reserves of $73 million, due to auto liability coverages development, and net increases primarily related to commercial lines of $18 million. Incurred claims and claims expense includes unfavorable catastrophe loss reestimates of $4 million, net of reinsurance and other recoveries, which include $34 million of unfavorable reestimates related to homeowners and $30 million of favorable reestimates, primarily related to auto.

Restructuring and Related Activities [Abstract]

Company Restructuring

Note 11 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 employee severance and relocation benefits, and post-exit rent expenses in connection with these programs, and non-cash charges resulting from pension benefit payments made to agents and certain legal expenses and settlements incurred in connection with the 1999 reorganization of Allstate’s multiple agency programs to a single exclusive agency program. The expenses related to these activities are included in the Condensed Consolidated Statements of Operations as restructuring and related charges, and totaled $22 million and $10 million during the three months ended March 31, 2018 and 2017, respectively. Restructuring expenses in 2018 primarily related to realignment of certain employees to centralized talent centers as well as legal expenses and settlements.

Guarantees and Contingent Liabilities

Guarantees and Contingent Liabilities

Guarantees and Contingent Liabilities

Note 12 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. Underwriting results related to these arrangements, which tend to be adverse, have been immaterial to the Company’s results of operations. Because of the Company’s participation, it may be exposed to losses that surpass the capitalization of these facilities and/or assessments from these facilities.

Guarantees

Related to the sale of Lincoln Benefit Life Company (“LBL”) on April 1, 2014, ALIC agreed to indemnify Resolution Life Holdings, Inc. in connection with certain representations, warranties and covenants of ALIC, and certain liabilities specifically excluded from the transaction, subject to specific contractual limitations regarding ALIC’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 disposal through reinsurance of substantially all of its variable annuity business to Prudential in 2006, the Company and its consolidated subsidiaries, ALIC and ALNY, have agreed to indemnify Prudential for certain pre-closing contingent liabilities (including extra-contractual liabilities of ALIC and ALNY and liabilities specifically excluded from the transaction) that ALIC and ALNY have agreed to retain. In addition, the Company, ALIC and ALNY will each indemnify Prudential for certain post-closing liabilities that may arise from the acts of ALIC, ALNY and their agents, including certain liabilities arising from ALIC’s and ALNY’s provision of transition services. The reinsurance agreements contain no limitations or indemnifications with regard to insurance risk transfer and transferred all of the future risks and responsibilities for performance on the underlying variable annuity contracts to Prudential, including those related to benefit guarantees. Management does not believe this agreement will have a material effect on results of operations, cash flows or financial position of the Company.

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.

The aggregate liability balance related to all guarantees was not material as of March 31, 2018.

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 agent 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, the Financial Industry Regulatory Authority, the Department of Labor, 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 $150 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 case of Jack Jimenez, et al. v. Allstate Insurance Company was filed in the U.S. District Court for the Central District of California in September 2010. Plaintiffs allege off-the-clock wage and hour claims and other California Labor Code violations resulting from purported unpaid overtime. Plaintiffs seek recovery of unpaid compensation, liquidated damages, penalties, and attorneys’ fees and costs. The court certified a class that includes all adjusters in the state of California, except auto field adjusters, from September 29, 2006 to final judgment. Allstate’s appeals to the Ninth Circuit Court of Appeals and then to the U.S. Supreme Court did not result in decertification. No trial date is calendared.

The case of Maria Victoria Perez and Kaela Brown, et al. v. Allstate Insurance Company was filed in the U.S. District Court for the Eastern District of New York in April 2011. Plaintiffs allege that no-fault claim adjusters have been improperly classified as exempt employees under New York Labor Law and the Fair Labor Standards Act. Plaintiffs seek unpaid wages, liquidated damages, injunctive relief, compensatory and punitive damages, and attorneys’ fees. On September 16, 2014, the court certified a class of no-fault adjusters under New York Labor Law and refused to decertify a Fair Labor Standards Act class of no-fault adjusters. The parties have concluded discovery and the court scheduled a jury trial on June 25, 2018.

Other proceedings The Company is defending a consolidated proceeding relating to the reorganization of its agent sales force in 2000, when the Company discontinued employee agent programs, terminated the contracts of its employee agents, and offered those agents the opportunity to become Allstate Exclusive Agent independent contractors or to take severance benefits in exchange for a release of claims. The consolidated proceeding, captioned Gene Romero, et al. v. Allstate Insurance Company, et al., is pending in the United States District Court for the Eastern District of Pennsylvania. The consolidated proceeding includes three separate cases filed in August 2001, December 2001, and December 2003.

The Court opted to resolve these proceedings in 4 phases. Phases 1, 2 and 3 are complete although the Company awaits final disposition in Phase 1. On January 30, 2018, the court decided two summary judgment motions filed by Allstate with respect to the Phase 4 claims. The court (i) granted summary judgment in Allstate’s favor on the claims by twenty-seven Phase 4 plaintiffs alleging that Allstate improperly retaliated against them by filing counterclaims to their original complaint; and (ii) declined to decide whether the remaining Phase 4 plaintiffs’ age discrimination (disparate treatment) claims should be dismissed due to their failure to exhaust administrative remedies.

In March 2018, the Company reached agreements to settle the claims of additional plaintiffs on a confidential basis, subject to negotiating and executing appropriate written settlement agreements, resulting in a total of 457 individual settlements to date. As a result of these settlements, plus several voluntary and involuntary dismissals of individual plaintiffs’ claims, there are 36 individual plaintiffs with claims remaining in the litigation. On April 11, 2018, the Company filed a motion for summary judgment as to the state law breach of contract and breach of fiduciary duty claims for fourteen of the remaining plaintiffs asserting that those claims are barred by statutes of limitations.

The court has established a Phase 4 schedule contemplating resolving this matter through trial, if necessary, by the end of 2018. The court has yet to decide the proper venue for such trials. The final resolution of these matters is subject to various uncertainties and complexities including how trials, post-trial motions, possible appeals with respect to the validity of the release, and any rulings on the merits will be resolved.

The two shareholder derivative actions described below are disclosed pursuant to SEC disclosure requirements for these types of matters, and the putative class action has been disclosed because these matters involve similar allegations.

In Biefeldt v. Wilson, et al., a plaintiff alleging to be a stockholder in the Company filed a shareholder derivative complaint in the Circuit Court for Cook County, Illinois, Chancery Division on August 3, 2017. The plaintiff seeks, on behalf of the Company, an unspecified amount of damages and various forms of equitable relief. The complaint alleges breaches of fiduciary duty based on allegations similar to those asserted in Inre The Allstate Corp. Securities Litigation. The complaint names as defendants the Company’s chairman and chief executive officer, its former president, its former chief financial officer, who is now the Company’s vice chairman, and the members of the board of directors during the relevant period. The defendants’ motion to dismiss the complaint is scheduled to be heard on May 8, 2018.

In IBEW Local No. 98 Pension Fund v. Wilson, et al., another plaintiff alleging to be a stockholder in the Company filed a shareholder derivative complaint in the Circuit Court for Cook County, Illinois, Chancery Division on April 12, 2018. The plaintiff seeks, on behalf of the Company, an unspecified amount of damages and various forms of equitable relief. The complaint alleges breaches of fiduciary duty based on allegations similar to those asserted in Inre The Allstate Corp. Securities Litigation. The complaint also includes allegations concerning the exercise of stock options by the Company’s chairman and several other members of our board of directors during the relevant period.  The complaint names as defendants the Company’s chairman and chief executive officer, its former president and the members of the board of directors during the relevant period.

Inre The Allstate Corp. Securities Litigation is a putative class action filed in November 2016 in the United States District Court for the Northern District of Illinois against the Company and several of its officers asserting claims under the federal securities laws. Plaintiffs seek an unspecified amount of damages, costs, attorney’s fees, and such 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. Plaintiffs’ further allege that a senior officer engaged in stock option exercises and sales during that time allegedly while in possession of nonpublic information about claim frequency. The Company, its chairman and chief executive officer and its former president are the named defendants. Defendants answered the complaint, disputing plaintiffs’ allegations that there was any misstatement or omission or other misconduct, after the court denied their motion to dismiss on February 27, 2018.

General [Abstract]

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 with various property and casualty and life and investment subsidiaries, including Allstate Life Insurance Company (“ALIC”) (collectively referred to as the “Company” or “Allstate”). 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, 2018 and for the three month periods ended March 31, 2018 and 2017 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, 2017. 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.

New Accounting Pronouncements

Adopted accounting standards

Recognition and Measurement of Financial Assets and Financial Liabilities

Effective January 1, 2018, the Company adopted new Financial Accounting Standards Board (“FASB”) guidance requiring equity investments, including equity securities and limited partnership interests not accounted for under the equity method of accounting or that do not result in consolidation to be measured at fair value with changes in fair value recognized in net income. The guidance clarifies that an entity should evaluate the realizability of deferred tax assets related to available-for-sale fixed income securities in combination with the entity’s other deferred tax assets. The Company’s adoption of the new FASB guidance included adoption of the relevant elements of Technical Corrections and Improvements to Financial Instruments, issued in February 2018.

Upon adoption of the new guidance on January 1, 2018, $1.16 billion of pre-tax unrealized net capital gains for equity securities were reclassified from AOCI to retained income. The after-tax change in accounting for equity securities did not affect the Company’s total shareholders’ equity and the unrealized net capital gains reclassified to retained income will never be recognized in net income.

Upon adoption of the new guidance on January 1, 2018, the carrying value of cost method limited partnership interests increased $224 million, pre-tax to fair value. The after-tax cumulative-effect increase in retained income of $177 million increased the Company’s shareholders’ equity but will never be recognized in net income thereby negatively impacting calculations of returns on equity.

Revenue from Contracts with Customers

Effective January 1, 2018, the Company adopted new FASB guidance which revises the criteria for revenue recognition. Insurance contracts are excluded from the scope of the new guidance. The Company’s principal activities impacted by the new guidance are those related to the issuance of protection plans for consumer products and automobiles and service contracts that provide roadside assistance. Under the guidance, the transaction price is attributed to underlying performance obligations in the contract and revenue is recognized as the entity satisfies performance obligations and transfers control of a good or service to the customer. Incremental costs of obtaining a contract may be capitalized to the extent the entity expects to recover those costs.

Adoption of the guidance on January 1, 2018 under the modified retrospective approach resulted in the recognition of an immaterial after-tax net cumulative effect increase to the beginning balance of retained income. In addition to the net cumulative effect, the Company also recorded in the statement of financial position an increase of approximately $160 million pre-tax in unearned premiums with a corresponding $160 million pre-tax increase in DAC for protection plans sold directly to retailers for which SquareTrade is deemed to be the principal in the transaction. These impacts offset fully and did not impact retained income at the date of adoption.

Presentation of Net Periodic Pension and Postretirement Benefits Costs

Effective January 1, 2018, the Company adopted new FASB guidance requiring identification, on the statement of operations or in disclosures, the line items in which the components of net periodic pension and postretirement benefits costs are presented. The new guidance permits only the service cost component to be eligible for capitalization where applicable. The adoption had no impact on the Company’s results of operations or financial position.

Goodwill Impairment

In January 2017, the FASB issued guidance to simplify the accounting for goodwill impairment which removes the second step of the goodwill impairment test that requires a hypothetical purchase price allocation. Under the new guidance, goodwill impairment will be measured and recognized as the amount by which a reporting unit’s carrying value, including goodwill, exceeds its fair value, not to exceed the carrying amount of goodwill allocated to the reporting unit. The revised guidance does not affect a reporting entity’s ability to first assess qualitative factors by reporting unit to determine whether to perform the quantitative goodwill impairment test. The guidance is to be applied on a prospective basis, with the effects, if any, recognized in net income in the period of adoption. The Company elected to early adopt the new guidance as of January 1, 2018. The adoption had no impact on the Company’s results of operations or financial position.

Changes to significant accounting policies

Investments

Changes were made to the Company’s Significant Accounting Policies upon adoption of new FASB guidance related to the recognition and measurement of financial assets. Equity securities primarily include common stocks, exchange traded and mutual funds, non-redeemable preferred stocks and real estate investment trust equity investments. Equity securities are carried at fair value. Equity securities without readily determinable or estimable fair values are measured using the measurement alternative which is cost less impairment, if any, and adjustments resulting from observable price changes in orderly transactions for the identical or similar investment of the same issuer. The periodic change in fair value of equity securities is recognized within realized capital gains and losses on the Condensed Consolidated Statements of Operations effective January 1, 2018.

Investments in limited partnership interests include interests in private equity funds, real estate funds and other funds. Where the Company’s interest is so minor that it exercises virtually no influence over operating and financial policies, investments in limited partnership interests purchased prior to January 1, 2018 are accounted for at fair value primarily utilizing the net asset value as a practical expedient (“NAV”) to determine fair value. All other investments in limited partnership interests, including those purchased subsequent to January 1, 2018, are accounted for in accordance with the equity method of accounting (“EMA”).

Investment income from limited partnership interests carried at fair value is recognized based upon the changes in fair value of the investee’s equity primarily determined using NAV. Income from EMA limited partnership interests is recognized based on the Company’s share of the partnerships’ earnings. Income from EMA limited partnership interests is generally recognized on a three month delay due to the availability of the related financial statements.

Recognition of Revenue

Revenues related to protection plans, other contracts (primarily finance and insurance products) and roadside assistance are deferred and earned over the term of the contract in a manner that recognizes revenue as obligations under the contracts are performed. Revenues from these products are classified as premiums as the products are backed by insurance. Protection plans and finance and insurance premiums are recognized using a cost-based incurrence method. Roadside assistance premiums are recognized evenly over the term of the contract as performance obligations are fulfilled.

Tax Reform

On December 22, 2017, Public Law 115-97, known as the Tax Cuts and Jobs Act of 2017 (“Tax Legislation”) became effective, permanently reducing the U.S. corporate income tax rate from 35% to 21% beginning January 1, 2018. As a result, the corporate tax rate is not comparable between periods.

Pending accounting standards

Accounting for Leases

In February 2016, the FASB issued guidance revising the accounting for leases. Under the new guidance, lessees will be required to recognize a right-of-use asset and lease liability for all leases other than those that meet the definition of a short-term lease. The lease liability will be equal to the present value of lease payments. A right-of-use asset will be based on the lease liability adjusted for qualifying initial direct costs. Recognition of the lease liability and right-of-use asset will result in an increase in total assets and liabilities in the Condensed Consolidated Statement of Financial Position. The expense of operating leases under the new guidance will be recognized in the income statement on a straight-line basis by adjusting the amortization of the right-of-use asset to produce a straight-line expense when combined with the interest expense on the lease liability. For finance leases, the expense components are computed separately and produce greater up-front expense compared to operating leases as interest expense on the lease liability is higher in early years and the right-of-use asset is amortized on a straight-line basis. Lease classification will be based on criteria similar to those currently applied. The accounting model for lessors will be similar to the current model with modifications to reflect definition changes for components such as initial direct costs. Lessors will continue to classify leases as operating, direct financing, or sales-type. The guidance is effective for reporting periods beginning after December 15, 2018, using a modified retrospective approach applied at the beginning of the earliest period presented. The FASB has exposed for comment an optional simplified transition approach that would allow application of the transition provisions at the effective date instead of the earliest date presented. The Company is in the process of evaluating the impact of adoption, which is not expected to be material to the Company’s results of operations or financial position.

Measurement of Credit Losses on Financial Instruments

In June 2016, the FASB issued guidance which revises the credit loss recognition criteria for certain financial assets measured at amortized cost, including reinsurance recoverables. The new guidance replaces the existing incurred loss recognition model with an expected loss recognition model. The objective of the expected credit loss model is for the reporting entity to recognize its estimate of expected credit losses for affected financial assets in a valuation allowance deducted from the amortized cost basis of the related financial assets that results in presenting the net carrying value of the financial assets at the amount expected to be collected. The reporting entity must consider all relevant information available when estimating expected credit losses, including details about past events, current conditions, and reasonable and supportable forecasts over the life of an asset. Financial assets may be evaluated individually or on a pooled basis when they share similar risk characteristics. The measurement of credit losses for available-for-sale debt securities measured at fair value is not affected except that credit losses recognized are limited to the amount by which fair value is below amortized cost and the carrying value adjustment is recognized through a valuation allowance and not as a direct write-down. The guidance is effective for reporting periods beginning after December 15, 2019, and for most affected instruments must be adopted using a modified retrospective approach, with a cumulative effect adjustment recorded to beginning retained income. The Company is in the process of evaluating the impact of adoption.

Accounting for Hedging Activities

In August 2017, the FASB issued amendments intended to better align hedge accounting with an organization’s risk management activities. The amendments expand hedge accounting for nonfinancial and financial risk components and revise the measurement methodologies to better align with an organization’s risk management activities. Separate presentation of hedge ineffectiveness is eliminated to provide greater transparency of the full impact of hedging by requiring presentation of the results of the hedged item and hedging instrument in a single financial statement line item. In addition, the amendments reduce complexity by simplifying the manner in which assessments of hedge effectiveness may be performed. The guidance is effective for reporting periods beginning after December 15, 2018. The presentation and disclosure guidance is effective on a prospective basis. The impact of adoption is not expected to be material to the Company’s results of operations or financial position.

Other revenue presentation

Concurrent with the adoption of new FASB guidance on revenue from contracts with customers and the Company’s objective of providing more information related to revenues for our Services Businesses, the Company revised the presentation of total revenue to include other revenue. Previously, components of other revenue were presented within operating costs and expenses and primarily represent fees collected from policyholders relating to premium installment payments, commissions on sales of non-proprietary products, fee-based services and other revenue transactions. Other revenue is recognized when performance obligations are fulfilled. Prior periods have been reclassified to conform to current separate presentation of other revenue.

Fair Value Measurement

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. The first is where 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. The second situation where the Company classifies securities in Level 3 is where 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 investments such as mortgage loans, bank loans, agent loans and policy loans. Accordingly, such investments are only included in the fair value hierarchy disclosure when the investment is subject to remeasurement at fair value after initial recognition and the resulting remeasurement is reflected in the condensed consolidated financial statements.

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 valuation techniques for assets and liabilities measured at fair value on a recurring basis

Level 1 measurements

• Fixed income securities: Comprise certain U.S. Treasury fixed income securities. Valuation is based on unadjusted quoted prices for identical assets in active markets that the Company can access.

• Equity securities: Comprise actively traded, exchange-listed equity securities. Valuation is based on unadjusted quoted prices for identical assets in active markets that the Company can access.

• Short-term: Comprise U.S. Treasury bills valued based on unadjusted quoted prices for identical assets in active markets that the Company can access and actively traded money market funds that have daily quoted net asset values for identical assets that the Company can access.

• Separate account assets: Comprise actively traded mutual funds that have daily quoted net asset values that are readily determinable for identical assets that the Company can access. Net asset values for the actively traded mutual funds in which the separate account assets are invested are obtained daily from the fund managers.

Level 2 measurements

• Fixed income securities:

U.S. government and agencies: 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.

Municipal: 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 - public: 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: 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.

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.

ABS - collateralized debt obligations (“CDO”) and ABS - consumer and other: 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, prepayment speeds, collateral performance and credit spreads. Certain ABS - CDO and ABS - consumer and other are valued based on non-binding broker quotes whose inputs have been corroborated to be market observable.

RMBS: 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, prepayment speeds, collateral performance and credit spreads.

CMBS: 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.

Redeemable preferred stock: 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, underlying stock prices and credit spreads.

• 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. For certain short-term investments, amortized cost is used as the best estimate of fair value.

• 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, 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, 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 in markets that exhibit less liquidity relative to those markets supporting Level 2 fair value measurements, 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 Corporate - privately placed: Primarily valued based on non-binding broker quotes where the inputs have not been corroborated to be market observable. Other inputs 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.

ABS - CDO, ABS - consumer and other, RMBS and CMBS: Valued based on non-binding broker quotes received from brokers who are familiar with the investments and where the inputs have not been corroborated to be market observable.

• Equity securities: The primary inputs to the valuation include quoted prices or quoted net asset values for identical or similar assets in markets that exhibit less liquidity relative to those markets supporting Level 2 fair value measurements.

• 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.

• Contractholder funds: Derivatives embedded in certain life and annuity contracts are valued internally using models widely accepted in the financial services industry that determine a single best estimate of fair value for the embedded derivatives within a block of contractholder liabilities. The models primarily use stochastically determined cash flows based on the contractual elements of embedded derivatives, projected option cost and applicable market data, such as interest rate yield curves and equity index volatility assumptions. These are categorized as Level 3 as a result of the significance of non-market observable inputs.

Assets and liabilities measured at fair value on a non-recurring basis

Mortgage loans written-down to fair value in connection with recognizing impairments are valued based on the fair value of the underlying collateral less costs to sell. EMA limited partnership interests written-down to fair value in connection with recognizing OTTI losses are generally valued using net asset values.

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. We receive distributions of income and from liquidation of the underlying assets of the investees over the life of these investments, typically 10-12 years. As of March 31, 2018, the Company has commitments to invest $943 million in limited partnership interests valued using NAV.

⁽²⁾  Unrealized net capital gains and losses for limited partnership interests represent the Company’s share of EMA limited partnerships’ other comprehensive income. Fair value and gross unrealized gains and losses are not applicable.

⁽³⁾  The insurance reserves adjustment represents the amount by which the reserve balance would increase if the net unrealized gains in the applicable product portfolios were realized and reinvested at current lower interest rates, resulting in a premium deficiency. This adjustment primarily relates to structured settlement annuities with life contingencies (a type of immediate fixed annuities).

⁽⁴⁾  The DAC and DSI adjustment balance represents the amount by which the amortization of DAC and DSI would increase or decrease if the unrealized gains or losses in the respective product portfolios were realized.
