Part I
Item 1.  Business
The Allstate Corporation was incorporated under the laws of the State of Delaware on November 5, 1992, to serve as the holding company for Allstate Insurance Company. Its business is conducted principally through Allstate Insurance Company, Allstate Life Insurance Company and other subsidiaries (collectively, including The Allstate Corporation, “Allstate”).
Allstate protects people from life’s uncertainties with a wide array of protection for autos, homes, electronic devices and identity theft. Allstate is primarily engaged in the property and casualty insurance business in the United States and Canada. Additionally, Allstate provides customers other protection solutions such as life, accident and health insurance and protection plans that cover electronic devices and personal identities.
The Allstate Corporation is one of the largest publicly held personal lines insurers in the United States. Allstate’s personal property-liability strategy is to increase market share by offering consumers a broad suite of personal lines solutions and a competitive value proposition across distribution channels. The Allstate brand is widely known through the “You’re In Good Hands With Allstate®” slogan. Allstate is the fourth largest personal property and casualty insurer in the United States on the basis of 2019 statutory direct premiums written according to A.M. Best.
Allstate also has strong market positions in other protection solutions. Allstate Benefits provides accident, health and life insurance through employers and is one of the top voluntary benefits carriers in the market based on a 2019 voluntary/worksite industry survey. Allstate Protection Plans provides protection plans on a wide variety of consumer goods such as cell phones, tablets, computers, furniture and appliances, and has a leading position in distribution through major retailers. Allstate Identity Protection, which provides identity protection, has a leading position in worksite distribution. In total, Allstate had 175.9 million policies in force (“PIF”) as of December 31, 2020.

In this Annual Report on Form 10-K, we occasionally refer to statutory financial information. All domestic United States insurance companies are required to prepare statutory-basis financial statements. As a result, industry data is available that enables comparisons between insurance companies, including competitors that are not required to prepare financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”). We frequently use industry publications containing statutory financial information to assess our competitive position.
Subsequent event On January 26, 2021, Allstate announced an agreement to sell Allstate Life Insurance Company (“ALIC”) and certain affiliates for $2.8 billion to Antelope US Holdings Company, an affiliate of an investment fund associated with The Blackstone Group Inc. Allstate will retain ownership of Allstate Life Insurance Company of New York (“ALNY”) while pursuing alternatives to sell or otherwise transfer risk to a third party. ALIC and certain affiliates represent approximately 80% of Allstate Life and Allstate Annuity reserves for life-contingent contract benefits and contractholder funds as of December 31, 2020 and generated net income of approximately $290 million and $470 million in 2020 and 2019, respectively. A loss on disposition estimated at $3 billion, after-tax, will be recorded in the first quarter of 2021. The ultimate amount of the loss on sale will be impacted by purchase price adjustments associated with certain pre-close transactions specified in the stock purchase agreement, changes in statutory capital and surplus prior to the closing date and the closing date equity of ALIC determined under GAAP, excluding unrealized gains and losses. The transaction is expected to close in the second half of 2021, subject to regulatory approvals and other customary closing conditions.
On January 4, 2021, Allstate completed the acquisition of National General Holdings Corp. (“National General”), expanding its independent agent channel business.

Additional Information and Strategy Updates
Commercial lines strategy We continue to focus on profitable expansion of our shared economy commercial lines business, which is primarily comprised of transportation network companies. Traditional small business commercial insurance is being enhanced through new product development using technology to improve customer experience and reduce costs while leveraging enterprise capabilities. Profit improvement actions continue for our traditional commercial lines insurance products, emphasizing pricing, claims, governance and operational improvements.
Independent agent strategy On January 4, 2021, we completed the acquisition of National General, significantly enhancing our strategic position in the independent agency channel. The transaction will increase our market share in personal property-liability by over one percentage point and enhance our independent agent-facing technology. It will significantly expand our distribution footprint, leading us to be a top five personal lines carrier in the independent agency distribution channel. Additional expansion opportunities through independent agents also exist in standard auto and homeowners insurance by leveraging Allstate’s capabilities.
National General provides personal and commercial automobile, homeowners, umbrella, recreational vehicle, motorcycle, lender-placed property, supplemental health and other niche insurance products. Auto insurance represents approximately 60% of premium with a significant presence in the non-standard auto market.
As part of the acquisition, Allstate Independent Agency and Encompass organizations will be integrated into National General by:
Migrating Encompass policyholders and business operations to National General and sunset Encompass infrastructure
Transitioning Allstate Independent Agent new business to National General as mid-market products roll out
Answer Financial strategy Answer Financial is an insurance agency that sells other insurance companies’ products directly to customers online. Our strategy as a technology-enabled insurance agency is to provide comparison shopping and related services for businesses, offering customers choice, convenience and ease of use.
Allstate Protection pricing and risk management strategies Our pricing and underwriting strategies and decisions are designed to generate sustainable profitable growth.
A proprietary database of underwriting and loss experience enables sophisticated pricing algorithms and methodologies to more accurately price risks while also seeking to attract and retain customers in multiple risk segments.
For auto insurance, risk evaluation factors can include, but are not limited to: vehicle make, model and year; driver age and marital status; territory; years licensed; loss history; years insured with prior carrier; prior liability limits; prior lapse in coverage; and insurance scoring utilizing telematics data and other consumer information.
For property insurance, risk evaluation factors can include, but are not limited to: the amount of insurance purchased; geographic location of the property; loss history; age, condition and construction characteristics of the property; and characteristics of the insured including insurance scoring utilizing other consumer information.
A combination of underwriting information, pricing and discounts are also used to achieve a more competitive position and growth. The pricing strategy involves local marketplace pricing and underwriting decisions based on risk evaluation factors to the extent permissible by applicable law and an evaluation of competitors.
Pricing of property products is intended to generate risk-adjusted returns that are acceptable over a long-term period. Rate increases are pursued to keep pace with loss trends, including losses from catastrophic events and those that are weather-related (such as wind, hail, lightning and freeze not meeting our criteria to be declared a catastrophe). We also take into consideration potential customer disruption, the impact on our ability to market our products, regulatory limitations, our competitive position and profitability.
In any reporting period, loss experience from catastrophic events and weather-related losses may contribute to negative or positive underwriting performance relative to the expectations incorporated into product pricing.
Property catastrophe exposure is managed with the goal of providing shareholders an acceptable return on the risks assumed in the property business. Catastrophe exposure management includes purchasing reinsurance to provide coverage for known exposure to hurricanes, earthquakes and fires following earthquakes, wildfires and other catastrophes. Our current catastrophe reinsurance program supports our risk tolerance framework that targets less than a 1% likelihood of annual aggregate catastrophe losses from hurricanes and earthquakes, excluding other catastrophe losses and, net of reinsurance, exceeding $2 billion.
The use of different assumptions and updates to industry models and to our risk transfer program could materially change the projected loss. Growth strategies include areas where we believe diversification can be enhanced and an appropriate return can be earned for the risk. As a result, our modeled exposure may increase, but in aggregate remain lower than $2 billion as noted above. In addition, we have exposure to other severe weather events and wildfires, which impact catastrophe losses.
The Allstate Corporation 5

Exclusive agent compensation structure The compensation structure for Allstate exclusive agents rewards them for delivering high value to customers and achieving certain business outcomes such as profitable growth and household penetration. Allstate exclusive agent remuneration comprises a base commission, variable compensation and a bonus.
Agents receive a monthly base commission payment as a percentage of their total eligible written premium.
Variable compensation rewards agents for acquiring new customers by exceeding a base production goal.
Bonus compensation is based on a percentage of premiums and can be earned by agents who are meeting certain sales goals and selling additional policies to meet customer needs profitably.
Compensation for 2021 includes a shift in variable compensation toward new business, including homeowners, and eliminates variable compensation for renewing customers. We are aligning agent compensation to emphasize growth while simultaneously improving customer service consistency.
Agents have the ability to earn commissions and additional bonuses on non-proprietary products provided to customers when an Allstate product is not available through Ivantage, a leading provider of property and casualty brokerage services, and arrangements made with other companies, agencies, and brokers.

Strategy  
Our Allstate Benefits segment accounted for 2.6% of Allstate’s 2020 consolidated total revenue and 2.2% of Allstate’s December 31, 2020 PIF. The Allstate Benefits segment provides consumers with financial protection against the risk of accidents, illness and mortality.

Pending Sale of ALIC and Certain Affiliates
We announced the pending sale of ALIC and certain affiliates, which represents approximately 90% of Allstate Life and 75% of Allstate Annuities reserves for life-contingent contract benefits and contractholder funds. Allstate will retain ownership of ALNY while pursuing alternatives to sell or otherwise transfer risk to a third party. We expect to discontinue sales of proprietary life insurance products during the second quarter of 2021.
Allstate Life Segment
Strategy  
Our Allstate Life segment accounted for 4.4% of Allstate’s 2020 consolidated total revenue and 1.1% of Allstate’s December 31, 2020 PIF.
Our strategy is to broaden Allstate’s customer relationships and value proposition. Target customers are middle market consumers with family and financial protection needs. Our business consists of traditional, interest-sensitive and variable life insurance sold through Allstate exclusive agents and exclusive financial specialists. Allstate exclusive agents and exclusive financial specialists also sell certain non-proprietary products offered by third-party providers, including mutual funds, fixed and variable annuities, disability insurance, and long-term care insurance to provide a broad suite of protection and retirement products. As of December 31, 2020, Allstate agencies had approximately $17.9 billion of non-proprietary mutual funds and fixed and variable annuity account balances under management. New and additional deposits into these non-proprietary products were $2.2 billion in 2020.
We will expand the non-proprietary product suite available for distribution to include a range of life insurance products offered by third-party providers.
Competition
We compete on a variety of factors, including product offerings, brand recognition, financial strength and ratings, price, distribution and customer service. The market for life insurance continues to be highly fragmented and competitive. As of December 31, 2019, there were approximately 335 groups of life insurance companies in the United States.

Allstate Annuities Segment
Strategy
Our Allstate Annuities segment accounted for 2.3% of Allstate’s 2020 consolidated total revenue and 0.1% of Allstate’s December 31, 2020 PIF. The Allstate Annuities segment consists primarily of deferred fixed annuities and immediate fixed annuities (including standard and sub-standard structured settlements).
The segment is in run-off and is focused on increasing lifetime economic value. Both the deferred and immediate annuity businesses have been adversely impacted by the historically low interest rate environment. Our immediate annuity business has also been impacted by medical advancements that have resulted in annuitants living longer than anticipated when many of these contracts were originated.
Allstate Annuities focuses on the distinct risk and return profiles of the specific products when developing investment and liability management strategies. The level of legacy deferred annuities in force has been significantly reduced and the investment portfolio and crediting rates are proactively managed to improve profitability of the business while providing appropriate levels of liquidity.
The investment portfolio supporting our immediate annuities is managed to ensure the assets match the characteristics of the liabilities and provide the long-term returns needed to support this business. To better match the long-term nature of our immediate annuities, we use performance-based investments (primarily limited partnership investments) in which we have ownership interests and a greater proportion of return is derived from idiosyncratic asset or operating performance.

Other Business Segments
Discontinued Lines and Coverages Segment
The Discontinued Lines and Coverages segment includes results from property and casualty insurance coverage that primarily relates to policies written during the 1960s through the mid-1980s.
Strategy Management of this segment has been assigned to a designated group of professionals with expertise in claims handling, policy coverage interpretation, exposure identification, litigation and reinsurance collection. As part of its responsibilities, this group pursues settlement agreements including policy buybacks on direct excess commercial business when appropriate to improve the certainty of the liabilities.  At the end of 2020, 67.0% of the direct excess gross case reserves were attributable to settlement agreements. This group also manages other direct commercial and assumed reinsurance business in runoff and engages in reinsurance ceded and assumed commutations as required or when considered economically advantageous.
Changes in the reserves established for asbestos, environmental and other discontinued lines losses have occurred and may continue. Reserve changes can be caused by new information relating to new and additional claims, new exposures or the impact of resolving unsettled claims based on unanticipated events such as arbitrations, litigation, legislative, judicial or regulatory actions. Environmental losses may also increase as the result of additional funding for environmental site clean-up.

Item 1. Business 2020 Form 10-K

Regulation
Allstate is subject to extensive regulation, primarily at the state level. The method, extent and substance of such regulation vary by state but generally have their source in statutes that establish standards and requirements for conducting the business of insurance and that also delegate regulatory authority to a state agency. These rules have a substantial effect on our business and relate to a wide variety of matters, including insurer solvency and statutory surplus sufficiency, reserve adequacy, insurance company licensing and examination, agent and adjuster licensing, agent and broker compensation, policy forms, rate setting, the nature and amount of investments, claims practices, participation in shared markets and guaranty funds, transactions with affiliates, the payment of dividends, underwriting standards, statutory accounting methods, trade practices, privacy regulation and data security, corporate governance and risk management. In addition, state legislators and insurance regulators continue to examine the appropriate nature and scope of state insurance regulation. For a discussion of statutory financial information, see Note 16 of the consolidated financial statements.
ALL-20201231_G16.JPG For a discussion of regulatory contingencies, see Note 14 of the consolidated financial statements. Notes 14 and 16 are incorporated in this Part I, Item 1 by reference.
As part of an effort to strengthen the regulation of the financial services market, the Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd-Frank”) was enacted in 2010. Dodd-Frank created the Federal Insurance Office (“FIO”) within the U.S. Department of the Treasury (“Treasury”). The FIO monitors the insurance industry, provides advice to the Financial Stability Oversight Council (“FSOC”), represents the U.S. on international insurance matters, and studies the current regulatory system.
Additional regulations or new requirements may emerge from the activities of various regulatory entities, including the Federal Reserve Board, FIO, FSOC, the National Association of Insurance Commissioners (“NAIC”), and the International Association of Insurance Supervisors (“IAIS”), that are evaluating solvency and capital standards for insurance company groups. In addition, the NAIC has adopted amendments to its model holding company law that have been adopted by some jurisdictions. The outcome of these actions is uncertain; however, these actions may result in an increase in the level of capital and liquidity required by insurance holding companies.
We cannot predict whether any specific state or federal measures will be adopted to change the nature or scope of the regulation of insurance or what effect any such measures would have on Allstate. We are working for changes in the regulatory environment to make insurance more available and affordable for customers, encourage market innovation, improve driving safety, strengthen cybersecurity, promote better catastrophe preparedness and loss mitigation
and advocate for appropriate long-term capital standards to support optimal risk adjusted returns.
Limitations on Dividends by Insurance Subsidiaries.    As a holding company with no significant business operations of its own, The Allstate Corporation relies on dividends from Allstate Insurance Company as one of the principal sources of cash to pay dividends and to meet its obligations, including the payment of principal and interest on debt or to fund non-insurance-related businesses. Allstate Insurance Company is regulated as an insurance company in Illinois, and its ability to pay dividends is restricted by Illinois law. The laws of the other jurisdictions that generally govern our other insurance subsidiaries contain similar limitations on the payment of dividends. However, such laws in some jurisdictions may be more restrictive.
ALL-20201231_G16.JPG For additional information regarding limitations, see Part II, Item 7 - Management’s Discussion and Analysis of Financial Condition and Results of Operations of this report.
In addition, the NAIC has formed a working group for the development of a group capital calculation covering all entities of the insurance company group for use in solvency monitoring activities. The calculation is intended to provide analytical information and we do not expect potential revisions to impact our current dividend plans, any increase in the amount of capital or reserves our insurance subsidiaries are required to hold could reduce the amount of future dividends such subsidiaries are able to distribute to the holding company.  Any reduction in the RBC ratios of our insurance subsidiaries could also adversely affect their financial strength ratings as determined by statistical rating agencies.
Insurance Holding Company Regulation – Change of Control.    The Allstate Corporation and Allstate Insurance Company are insurance holding companies subject to regulation in the jurisdictions in which their insurance subsidiaries, including the insurance subsidiaries of National General, do business. In the U.S., these subsidiaries are organized under the insurance codes of Alabama, California, Florida, Illinois, Indiana, Massachusetts, Michigan, Mississippi, Missouri, New Jersey, New York, North Carolina, South Carolina and Texas. Additionally, some of these subsidiaries are considered commercially domiciled in California and Florida.
Generally, the insurance codes in these states provide that the acquisition or change of “control” of a domestic or commercially domiciled insurer or of any person that controls such an insurer cannot be consummated without the prior approval of the relevant insurance regulator. In general, a presumption of “control” arises from the ownership, control, possession with the power to vote, or possession of proxies with respect to ten percent or more of the voting securities of an insurer or of a person who controls an insurer. In addition, certain state insurance laws require pre-acquisition notification to state
The Allstate Corporation 13

2020 Form 10-K Item 1. Business
agencies of a change in control with respect to a non-domestic insurance company licensed to do business in that state. While such pre-acquisition notification statutes do not authorize the state agency to disapprove the change of control, such statutes do authorize certain remedies, including the issuance of a cease-and-desist order with respect to the non-domestic insurer if certain conditions exist, such as undue market concentration.
Thus, any transaction involving the acquisition of ten percent or more of The Allstate Corporation’s common stock would generally require prior approval by the state insurance departments in Alabama (where the threshold is five percent or more of The Allstate Corporation’s common stock), California, Florida, Illinois, Indiana, Massachusetts, Michigan, Mississippi, Missouri, New Jersey, New York, North Carolina, South Carolina and Texas. Moreover, notification would be required in those other states that have adopted pre-acquisition notification provisions and where the insurance subsidiaries are admitted to transact business. Such approval requirements may deter, delay or prevent certain transactions affecting the ownership of The Allstate Corporation’s common stock.
Rate Regulation.    Nearly all states have insurance laws requiring personal property and casualty insurers to file rating plans, policy or coverage forms, and other information with the state’s regulatory authority. In many cases, such rating plans, policy forms, or both must be approved prior to use.
The speed with which an insurer can change rates in response to competition or increasing costs depends on the state rating laws, which include the following categories:
Prior approval — Regulators must approve a rate before the insurer may use it
File-and-use — Insurers do not have to wait for the regulator’s approval to use a rate, but the rate must be filed with the regulatory authority prior to being used
Use-and-file — Requires an insurer to file rates within a certain period of time after the insurer begins using them
No approval — One state, with an immaterial amount of written premiums, does not impose a rate filing requirement
Under these rating laws, the regulator has the authority to disapprove a rate filing. The percentage of 2020 statutory direct written premiums based on state rating laws are reflected below.
ALL-20201231_G17.JPG
An insurer’s ability to adjust its rates in response to competition or to changing costs is dependent on an insurer’s ability to demonstrate to the regulator that its rates or proposed rating plan meets the requirements of the rating laws. In those states that significantly restrict an insurer’s discretion in selecting the business that it wants to underwrite, an insurer can manage its risk of loss by charging a rate that reflects the cost and expense of providing the insurance. In those states that significantly restrict an insurer’s ability to charge a rate that reflects the cost and expense of providing the insurance, the insurer can manage its risk of loss by being more selective in the type of business it underwrites. When a state significantly restricts both underwriting and pricing, it becomes more difficult for an insurer to maintain its profitability.
From time to time, the personal lines insurance industry comes under pressure from state regulators, legislators, and special-interest groups to reduce, freeze, or set rates at levels that do not correspond with our analysis of underlying costs, catastrophe loss exposure, and expenses. We expect this kind of pressure to persist. Allstate and other insurers are using increasingly sophisticated pricing models and rating plans that are reviewed by regulators and special-interest groups. State regulators may interpret existing law or rely on future legislation or regulations to impose new restrictions that adversely affect profitability or growth. We cannot predict the impact on our business of possible future legislative and regulatory measures regarding insurance rates.
Involuntary Markets.    As a condition of maintaining our licenses to write personal property and casualty insurance in various states, we are required to participate in assigned risk plans, reinsurance facilities, and joint underwriting associations that provide various types of 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 our results of operations.
ALL-20201231_G16.JPG For a discussion of these items see Note 14 of the consolidated financial statements. Note 14 is incorporated in this Part I, Item 1 by reference.
Indemnification Programs.    We are a participant in state-based industry pools, facilities or associations, mandating participation by insurers offering certain coverage in their state, including the Michigan Catastrophic Claims Association (“MCCA”), the New Jersey Property-Liability Insurance Guaranty Association, the North Carolina Reinsurance Facility and the Florida Hurricane Catastrophe Fund. We also participate in the Federal Government National Flood Insurance Program.
Recent regulatory changes have occurred related to the MCCA. At this time, we are unable to determine whether, or to what extent, these changes will have on our claims and claims expense reserves and corresponding MCCA indemnification recoverables.
On August 6, 2020, member companies of the MCCA were notified of the ratification of
14 www.allstate.com

Item 1. Business 2020 Form 10-K

amendments to the MCCA’s Plan of Operation. The amendments were designed to align the Plan of Operation with Public Acts 21 and 22, which passed in 2019.
On July 2, 2020, portions of Public Acts 21 and 22 went into effect. The changes under those laws include:
Allowing insureds to choose levels of personal injury protection coverage, including the option to opt-out of personal injury protection coverage in certain circumstances.
Implementing mandated rate reductions that correspond to the level of personal injury protection coverage chosen by insureds.
Implementing or creating new processes for reviewing claims, assessing allowable expenses and setting limits on certain allowable expenses.
On July 2, 2021, legislation passed in 2019 will become effective, setting fee schedules for personal injury protection claims. Such fee schedules will be set at 200% of Medicare rates in 2021, declining to 195% in 2022 and 190% in 2023, for any providers other than certain unique categories of providers and applying to treatment on existing and new claims.
Other legislative proposals to change the MCCA operation in the future and to adjust Public Acts 21 and 22 are put forth periodically.
ALL-20201231_G16.JPG For a discussion of these items see Note 10 of the consolidated financial statements. Note 10 is incorporated in this Part I, Item 1 by reference.
Guaranty Funds.    Under state insurance guaranty fund laws, insurers doing business in a state can be assessed, up to prescribed limits, in order to cover certain obligations of insolvent insurance companies. We do not anticipate any material adverse financial impact on Allstate from these assessments.
Investment Regulation.    Our insurance subsidiaries are subject to state regulation that specifies the types of investments that can be made and concentration limits of invested assets. Failure to comply with these rules leads to the treatment of non-conforming investments as non-admitted assets for purposes of measuring statutory surplus. Further, in some instances, these rules require divestiture of non-conforming investments.
Exiting Geographic Markets; Canceling and Non-Renewing Policies.    Most states regulate an insurer’s ability to exit a market. For example, states may limit, to varying degrees, an insurer’s ability to cancel and non-renew policies. Some states restrict or prohibit an insurer from withdrawing one or more types of insurance business from the state, except pursuant to a plan that is approved by the state insurance department. Regulations that limit cancellation and non-renewal and that subject withdrawal plans to prior approval requirements may restrict an insurer’s ability to exit unprofitable markets.
Variable Life Insurance and Registered Fixed Annuities.    The sale and administration of variable life insurance and registered fixed annuities with market value adjustment features are subject to extensive regulatory oversight at the federal and state level, including regulation and supervision by the Securities and Exchange Commission (“SEC”) and the Financial Industry Regulatory Authority (“FINRA”).
Broker-Dealers, Investment Advisors and Investment Companies.    The Allstate entities that operate as broker-dealers, registered investment advisors, and investment companies are subject to regulation and supervision by the SEC, FINRA and/or, in some cases, state securities administrators. Certain state and federal regulators are considering or have implemented best interest or fiduciary standards. Such standards could impact products provided by Allstate agents and Allstate’s broker-dealers, their sales processes, sales volume, and producer compensation arrangements.
Dodd-Frank: Covered Agreement. The Secretary of the Treasury (operating through FIO) and the Office of the U.S. Trade Representative (“USTR”) are jointly authorized, pursuant to the Dodd-Frank, to negotiate Covered Agreements. A Covered Agreement is a bilateral or multilateral agreement that “relates to the recognition of prudential measures with respect to the business of insurance or reinsurance that achieves a level of protection for insurance or reinsurance consumers that is substantially equivalent to the level of protection achieved under State insurance or reinsurance regulation.”
On September 22, 2017, the U.S. and European Union (“EU”) signed a Covered Agreement. In addition to signing the Covered Agreement, Treasury and the USTR jointly issued a policy statement clarifying how the U.S. views implementation of certain provisions of the Covered Agreement. The policy statement affirms the U.S. system of insurance regulation, including the role of state insurance regulators as the primary supervisors of the business of insurance and addresses several other key provisions of the Covered Agreement for which constituents sought clarity, including prospective application to reinsurance agreements and an affirmation that the Covered Agreement does not require development of a group capital standard or group capital requirement in the U.S.
The U.S. has five years from the date of signing to amend its credit for reinsurance laws and regulations to conform with the requirements of the Covered Agreement or face federal preemption determinations by the FIO. To address the requirements of the Covered Agreement, the NAIC has formally adopted revisions to its existing credit for reinsurance model law and model regulation to conform with the requirements of the Covered Agreement with the expectation that states will adopt and implement the modified model law and regulation by September 2022.
On December 19, 2018, the U.S. and the United Kingdom (“UK”) signed a separate Covered Agreement consistent with the U.S.-EU Covered Agreement to
The Allstate Corporation 15

2020 Form 10-K Item 1. Business
coordinate regulation of the insurance industry doing business in the U.S. and UK. Consistent with the U.S.-EU Covered Agreement (the “Agreement”) signed in 2017, Treasury and the USTR also issued a policy statement regarding implementation of the Agreement affirming the role that state insurance regulators play as the primary supervisors of the U.S. insurance industry.
Division Statute. On November 27, 2018, the Illinois General Assembly passed legislation authorizing a statute that makes available a process by which a domestic insurance company may divide into two or more domestic insurance companies. The statute, which became effective January 1, 2019, can be used to divide continuing blocks of insurance business from insurance business no longer marketed, or otherwise has been discontinued, into separate companies with separate capital. The statute can also be used for sale to a third party or to manage risks associated with indemnification programs. Before a plan of division can be effected it must be approved according to the organizational documents of the dividing insurer and submitted for approval by the Illinois Department of Insurance.
Privacy Regulation and Data Security.    Federal law and the laws of many states require financial institutions to protect the security and confidentiality of consumer information and to notify consumers about their policies and practices relating to collection, use, and disclosure of consumer information and their policies relating to protecting the security and confidentiality of that information. Federal law and the laws of many states also regulate disclosures and disposal of consumer information. Congress, state legislatures, and regulatory authorities are expected to consider additional regulation relating to privacy and other aspects of consumer information.
For example, the California Consumer Privacy Act, which took effect in January 2020, adopted significant compliance requirements for businesses that collect personal information on California residents. In addition, the California Privacy Rights Act, which expands consumer privacy rights and establishes a new privacy regulatory agency, was passed in November 2020 and will become effective in January 2023. Further, the New York State Department of Financial Services cybersecurity regulation and the NAIC Insurance Data Security Model Law, which has been adopted in some form by several states, establish standards for data security and for the investigation of and notification to insurance commissioners of cybersecurity events. Additional states are also likely to adopt similarly themed cybersecurity requirements in the future. We cannot predict the impact on our business of possible future legislative measures regarding privacy or cybersecurity.
Asbestos.    Congress has repeatedly considered legislation to address asbestos claims and litigation in the past. We cannot predict the impact on our business of possible future legislative measures regarding asbestos.
Environmental.    Environmental pollution and clean-up of polluted waste sites is the subject of federal and state regulation. The Comprehensive Environmental Response Compensation and Liability Act of 1980 (the “Superfund”) and comparable state statutes (the “mini-Superfunds”) govern the clean-up and restoration of waste sites by Potentially Responsible Parties (“PRPs”). The Superfund and the mini-Superfunds (collectively, the “Environmental Clean-up Laws” or “ECLs”) establish a mechanism to assign liability to PRPs or to fund the clean-up of waste sites if PRPs fail to do so. The extent of liability to be allocated to a PRP depends on a variety of factors. The insurance industry is involved in extensive litigation regarding coverage issues arising out of the clean-up of waste sites by insured PRPs and the insured parties’ alleged liability to third parties responsible for the clean-up. The insurance industry, including Allstate, has disputed and is disputing many such claims. Key coverage issues include whether the Superfund response, investigation, and clean-up costs are considered damages under the policies; whether coverage has been triggered; whether any pollution exclusion applies; whether there has been proper notice of claims; whether administrative liability triggers the duty to defend; whether there is an appropriate allocation of liability among potentially responsible insurers; and whether the liability in question falls within the definition of an “occurrence.” Identical coverage issues exist for clean-up and waste sites not covered under the Superfund. To date, courts have been inconsistent in their rulings on these issues.
Allstate’s exposure to liability with regard to its insureds that have been, or may be, named as PRPs is uncertain. While comprehensive Superfund reform proposals have been introduced in Congress, only modest reform measures have been enacted. In May 2017, the Environmental Protection Agency created a Superfund Task Force that issued proposed reforms in a July 2018 report. These recommendations address expediting clean-up and remediation processes, reducing the financial burden of the clean-up process, encouraging private investment, promoting redevelopment and community revitalization, and building and strengthening partnerships. We cannot predict which, if any, of these reforms will be enacted.
Developments in the insurance and reinsurance industries have fostered a movement to segregate asbestos, environmental and other discontinued lines exposures into separate legal entities with dedicated capital. Regulatory bodies in certain cases have supported these actions. We are unable to determine the impact, if any, that these developments will have on the collectability of reinsurance recoverables in the future.

ALL-20201231_G18.JPG Human Capital
Allstate’s success is highly dependent on human capital. The wellbeing of our employees is a key priority, and Allstate strives to promote a dynamic and welcoming workplace that promotes inclusive diversity and equity, fosters collaboration and encourages employees to bring their best ideas to work every day. As of December 31, 2020, Allstate had approximately 41,860 full-time employees and 300 part-time employees.
Allstate’s human capital management focuses on the following priorities:
Inclusive Diversity and Equity (“IDE”) We strive for a workforce where the breadth of our diversity makes us a better company. IDE is one of Allstate’s core values and serves as a foundation of Our Shared Purpose.
U.S. workforce diversity as of December 31, 2020
Women 55%
Racially and ethnically diverse 39%
We track our workforce composition data over time to determine if we are making appropriate progress in advancing gender and racial representation in our employee population and we disclose our progress. In our Sustainability Report, we provide, among other things, five years of workforce composition data that shows a breakdown of salaried, hourly and management employees by gender and race.
As part of our commitment to fair and equitable compensation practices, we complete an annual pay equity analysis. Over the past two years, we engaged an external firm to provide a more detailed analysis to identify potential pay gaps across substantially similar employee groups as well as identify policies, practices or systematic issues that may contribute to pay gaps now or over time. The external analyses found that Allstate’s results compared well to benchmarks for companies of similar size and scope.
Allstate’s Employee Resource Group (“ERG”) Program and the Enterprise Diversity Leadership Council (“EDLC”) help advance IDE.
ERGs: We support and fund 11 ERGs. ERGs offer specific opportunities for employees to partner and collaborate with each other through professional development workshops, recruiting events, volunteer projects and mentoring. Officers from across the enterprise, leverage their time, networks and resources to support the ERGs and advance IDE at Allstate.
EDLC: The EDLC is made up of senior leaders throughout the organization and focuses on driving targeted results for IDE by identifying and prioritizing action, taking accountability for achieving targeted results and ensuring
clarity and understanding of the business relevance of IDE. The EDLC provides updates to our chief executive officer.
In 2020, employees completed 30,827 courses on IDE. The number of courses completed in June through December 2020 comprised more than double the total of IDE courses completed in all of 2019. Three new virtual, instructor-led sessions were launched in July 2020, in line with our focus on reflection, learning and action.
Allstate continues to look for ways to build awareness and drive action. In response to the unprecedented events in 2020, we:
Began observing Juneteenth as an annual company holiday
Launched an Anti-Racism Resource Center for employees
Expanded the “Inclusive Conversations” series to monthly, hosted, enterprise-level sessions to build off themes of racial inequity, allyship, privilege and other relevant topics
Founding member of OneTen (with other leading CEOs and organizations), an organization committed to upskilling, hiring and promoting one million Black Americans over the next 10 years into family-sustaining jobs with opportunities for advancement
An external comprehensive IDE assessment will be completed in 2021 and will include a full assessment of our programs, policies, processes, procedures, and practices to ensure that we are building, maintaining and supporting fully sustainable and equitable programs at Allstate.
Employee Wellbeing and Safety We take seriously our responsibility to care for employees’ well-being, devoting resources to employee health and safety.
The Coronavirus made Allstate even more focused on employees’ health and safety.
In just one week, we transitioned 95% of our workforce to working remotely.
As part of the Good Office program, we shipped over 50,000 office items to our employees to help them work more productively at home.
We established Coronavirus hotlines for employees and continued to pay employees who could not work remotely under shelter-in-place orders.
During the fourth quarter of 2020, we announced the Holiday Support Program, which helped provide financial relief to approximately 5,000 employees experiencing financial hardships due to the Coronavirus.
Enhanced safety guidelines, cleaning protocols and social distancing practices remain in place for in-office workers.
The Allstate Corporation 17

2020 Form 10-K Item 1. Business
We conduct wellbeing assessments for employees to help determine which services, programming and benefits to offer the workforce. The assessment asks about physical, emotional, mental and financial wellbeing. Completing the assessment lowers the cost of benefits to employees.
We offer resilience and stress management programs to improve employee wellbeing, including Energy for Life, a workshop on employee wellness to help employees articulate and pursue their individual purpose and embrace new challenges with ease. Over 39,000 employees have taken this wellness workshop since 2010.
The ERGs provided multiple forums in 2020 to share wellness resources and support for their members.
Wellbeing Champions promote Allstate’s health and wellness resources across the enterprise, including yoga and meditation classes and flu shots.
Talent Recruitment and Management We seek to provide employees with rewarding work, professional growth and educational opportunities.
Our flexible work and equal opportunity policies support talent attraction and retention.
Employees receive an annual performance review, with additional performance conversations taking place throughout the year. Allstate invests in training and re-skilling opportunities so employees can be successful throughout their careers. In 2020:
Employees completed over 139,000 hours in formal learning opportunities.
7,000 employees attended Allstate’s Global Learning Week, with over 2,000 development commitments made to grow one new skill by the end of the year.
Over 1,000 employees attended Quarterly Skill Builders featuring external experts facilitating topics including data visualization, storytelling and talent development.
702 employees participated in Allstate’s tuition reimbursement program, with $3.3 million paid in tuition reimbursement.
42% of open positions were filled with internal applicants.
The Power of Mentoring for Inclusive Diversity (“MInD”) program engaged 74 women and racially and ethnically diverse high potential managers, senior managers and directors who were nominated to receive sponsorship, job shadowing, and networking opportunities.
Organizational Culture At Allstate, we believe that when your passion fuels your purpose, you can achieve anything. We expect all employees to be leaders and dedicate extensive resources to developing leaders at all levels.
Allstate defines culture as a self-sustaining system of shared values, priorities and principles that shape beliefs and drive behaviors and decision-making within an organization.
In 2020, we updated Our Shared Purpose to reflect the evolution of our culture to drive our business strategy.

Item 1A.  Risk Factors
Summary Risks are categorized by (1) insurance and financial services, (2) business, strategy and operations and (3) macro, regulatory and risk environment. Many risks may affect more than one category and are included where the impact is most significant. If some of these risk factors occur, they may cause the emergence of or exacerbate the impact of other risk factors, which could materially increase the severity of the impact of these risks on our business, results of operations, financial condition or liquidity. The table below includes examples of risks from each category.

Consider these cautionary statements carefully together with other factors discussed elsewhere in this document, in filings with the Securities and Exchange Commission (“SEC”) or in materials incorporated therein by reference.
ALL-20201231_G19.JPG
Insurance and financial services
Unexpected increases in the frequency or severity of property and casualty claims may adversely affect our results of operations and financial condition
A significant increase in claim frequency could adversely affect our results of operations and financial condition. Changes in mix of business, miles driven, weather, distracted driving or other factors can lead to changes in auto claim frequency. We may experience volatility in claim frequency, and short-term trends may not be predictive of future losses over the longer term.
Increases in claim severity can arise from numerous causes that are inherently difficult to predict. The following factors may impact claim severity for auto bodily injury, property damage and homeowners coverages:
Bodily injury — inflation in medical costs, litigation trends and precedents and regulation
Vehicle property damage — inflation in repair costs, including parts and labor rates, mix of total losses declared, costs associated with repairing sophisticated newer vehicles, model year and used-car values
Homeowners — inflation in the construction industry, building materials and home furnishings, changes in the mix of loss type, and other economic and environmental factors, including
short-term supply imbalances for services and supplies in areas affected by catastrophes
Catastrophes and severe weather events may subject us to significant losses
Catastrophic events could adversely affect operating results and cause them to vary significantly from one period to the next. Also, our liquidity could be constrained by a catastrophe, or multiple catastrophes, which could result in extraordinary losses, sales of investments or a downgrade of our debt or financial strength ratings.
Catastrophic losses are caused by wind and hail, wildfires, tornadoes, hurricanes, tropical storms, earthquakes, volcanic eruptions, terrorism and industrial accidents and other such events.
Our personal property insurance business may incur catastrophe losses greater than:
Those experienced in prior years
The average expected level used in pricing
Current reinsurance coverage limits
Loss estimates from hurricane and earthquake models at various levels of probability
Property and casualty businesses are subject to claims arising from severe weather events such as winter storms, rain, hail and high winds. The incidence and severity of weather conditions resulting in claims are unpredictable.
The total number of policyholders affected by the event, the severity of the event and the coverage
22 www.allstate.com

                     Part I - Item 1A. Risk Factors and Other Disclosures 2020 Form 10-K
provided contribute to catastrophe and severe weather losses. Increases in the insured values of covered property, geographic concentration and the number of policyholders exposed to certain events could increase the severity of claims from catastrophic and severe weather events.
Limitations in analytical models used to assess and predict the exposure to catastrophe losses may adversely affect our results of operations and financial condition
We use internally developed and third-party vendor models along with our own historical data to assess exposure to catastrophe losses. The models assume various conditions and probability scenarios and may not accurately predict future losses or measure losses currently incurred.
Price competition and changes in underwriting standards in property and casualty businesses may adversely affect our results of operations and financial condition
The personal property-liability market is highly competitive with carriers competing through underwriting, advertising, price, customer service, innovation and distribution.  Companies can alter underwriting standards, lower prices and increase advertising, which could result in lower growth or profitability for Allstate.   A decline in the growth or profitability of the property and casualty businesses could have a material effect on our results of operations and financial condition.
Property and casualty actual claims costs may exceed current reserves established for claims due to changes in the inflationary, regulatory and litigation environment
Estimating claim reserves is an inherently uncertain and complex process as losses are unknown at the time policies are sold. We continually refine our best estimates of losses after considering known facts and interpretations of the circumstances.
Our reserving methodology may be impacted by the following:
Models that rely on the assumption that past loss development patterns will persist into the future
Internal factors including experience with similar cases, actual claims paid, historical trends involving claim payment patterns, pending levels of unpaid claims, loss management programs, product mix, contractual terms and changes in claim reporting and settlement practices
External factors such as inflation, court decisions, changes in law or litigation imposing unintended coverage, regulatory requirements, changes in driving patterns and economic conditions
The ultimate cost of losses may vary materially from recorded reserves and such variance may adversely affect our results of operations and financial condition as the reserves and amounts due from reinsurers are reestimated.
ALL-20201231_G16.JPG See MD&A, Application of Critical Accounting Estimates for further details.
Our investment portfolios are subject to market risk and declines in quality which may adversely affect or create volatility in our investment income and cause realized and unrealized losses
We continually evaluate investment management strategies since we are subject to risk of loss due to adverse changes in interest rates, credit spreads, equity prices, real estate values, currency exchange rates and liquidity. Adverse changes may occur due to changes in monetary and fiscal policy and the economic climate, liquidity of a market or market segment, investor return expectations or risk tolerance, insolvency or financial distress of key market makers or participants, or changes in market perceptions of credit worthiness. Adverse changes in market conditions could cause the value of our investments to decrease significantly and impact our results of operations and financial condition.
Our investments are subject to risks associated with economic and capital market conditions and factors that may be unique to our portfolio, including:
General weakening of the economy, which is typically reflected through higher credit spreads and lower equity and real estate valuations
Declines in credit quality
Declines in market interest rates, credit spreads or sustained low interest rates could lead to further declines in portfolio yields and investment income
Increases in market interest rates, credit spreads or a decrease in liquidity could have an adverse effect on the value of our fixed income securities that form a substantial majority of our investment portfolios
Weak performance of general and joint venture partners and underlying investments unrelated to general market or economic conditions could lead to declines in investment income and cause realized losses in our limited partnership interests
Concentration in any particular issuer, industry, collateral type, group of related industries, geographic sector or risk type
The amount and timing of net investment income, capital contributions and distributions from our performance-based investments, which primarily include limited partnership interests, can fluctuate significantly due to the underlying investments’ performance or changes in market or economic conditions. Additionally, these investments are less liquid than similar, publicly-traded investments and a decline in market liquidity could impact our ability to sell them at their current carrying values.
Declining equity markets or increases in interest rates or credit spreads could cause the value of the investments in our pension plans to decrease. Declines in interest rates could cause the funding ratio to decline and the value of the obligations for our pension and postretirement plans to increase. These factors could decrease the funded status of our pension and postretirement plans, increasing the likelihood or magnitude of future benefit expense and contributions.
The Allstate Corporation 23

2020 Form 10-K Part I - Item 1A. Risk Factors and Other Disclosures

Determination of the fair value and amount of credit losses for investments includes subjective judgments and could materially impact our results of operations and financial condition
The valuation of the portfolio is subjective, and the value of assets may differ from the actual amount received upon the sale of an asset. The degree of judgment required in determining fair values increases when:
Market observable information is less readily available
The use of different valuation assumptions may have a material effect on the assets’ fair values
Changing market conditions could materially affect the fair value of investments
The determination of the amount of credit losses varies by investment type and is based on ongoing evaluation and assessment of known and inherent risks associated with the respective asset class or investment.
Such evaluations and assessments are highly judgmental and are revised as conditions change and new information becomes available.
We update our evaluations regularly and reflect changes in credit losses in our results of operations. Our conclusions may ultimately prove to be incorrect as assumptions, facts and circumstances change. Historical loss trends, consideration of current conditions, and forecasts may not be indicative of future changes in credit losses and additional amounts may need to be recorded in the future.
Changes in market interest rates or performance-based investment returns may lead to a significant decrease in the profitability of our annuity business
Spread-based products, such as fixed annuities, are dependent upon maintaining profitable spreads between investment returns and interest crediting rates. When market interest rates decrease or remain at low levels, investment income may decline. Lowering interest crediting rates on some products in such an environment can partially offset decreases in investment yield. However, these changes could be limited by regulatory minimum rates or contractual minimum rate guarantees on many contracts and may not match the timing or magnitude of changes in investment yields.
Increases in market interest rates can lead to increased surrenders at a time when fixed income investment asset values are lower due to the increase in interest rates. Liquidating investments to fund surrenders could result in a loss that would adversely impact results of operations.
Performance-based net investment income, capital contributions and distributions can fluctuate significantly due to the underlying investments’ performance or changes in market or economic conditions.
Changes in reserve estimates and amortization of deferred acquisition costs (“DAC”) could materially affect results of operations and financial condition of our life, voluntary benefits and annuity businesses
We use long-term assumptions, including future investment yields, mortality, morbidity, persistency and expenses in pricing and valuation. If experience differs significantly from assumptions, adjustments to reserves and amortization of DAC may be required that could have a material adverse effect on our results of operations and financial condition.
ALL-20201231_G16.JPG See MD&A, Application of Critical Accounting Estimates and Note 2 of the consolidated financial statements for further details.
Our participation in indemnification programs subjects us to the risk that reimbursement for qualifying claims and claims expenses may not be received
Participation in state-based industry pools, facilities and associations as well as the National Flood Insurance Program may have a material, adverse effect on our results of operations and financial condition. Our largest exposure is associated with the Michigan Catastrophic Claim Association (“MCCA”), a state-mandated indemnification mechanism for qualified personal injury protection losses that exceed a specified level. To the extent the MCCA’s current and future assessments are insufficient to reimburse its ultimate obligation on existing claims to member companies, our ability to obtain the 100% indemnification of ultimate loss could be impaired.
ALL-20201231_G16.JPG For further discussion of these items, see Regulation section, Indemnification Programs and Note 10 of the consolidated financial statements.
We may not be able to mitigate the capital impact associated with statutory reserving and capital requirements
Regulatory capital and reserving requirements affect the amount of capital required to be maintained by our subsidiary insurance companies.  Changes to capital or reserving requirements or regulatory interpretations may result in additional capital held in our insurance companies and could require us to increase prices, reduce our sales of certain products, or accept a return on equity below original levels assumed in pricing.
A downgrade in financial strength ratings may have an adverse effect on our business
Financial strength ratings are important factors in establishing the competitive position of insurance companies and their access to capital markets. Rating agencies could downgrade or change the outlook on our ratings due to:
Changes in the financial profile of one of our insurance companies
Changes in a rating agency’s determination of the amount of capital required to maintain a particular rating
Increases in the perceived risk of our investment portfolio, a reduced confidence in management or
24 www.allstate.com

                     Part I - Item 1A. Risk Factors and Other Disclosures 2020 Form 10-K
our business strategy, or other considerations that may or may not be under our control
A downgrade in our ratings could have a material effect on our sales, competitiveness, customer retention, the marketability of our product offerings, liquidity, access to and cost of borrowing, results of operations and financial condition.
Changes in tax laws may adversely affect the sales and profitability of life insurance products
Changes in taxation of life insurance products could reduce sales and result in the surrender of some existing contracts and policies, which may have a material effect on our profitability and financial condition.
ALL-20201231_G20.JPG
Business, strategy and operations
We operate in markets that are highly competitive and may be impacted by new or changing technologies
Markets in which we operate are highly competitive, and we must continually allocate resources to refine and improve products and services to remain competitive. If we are unsuccessful in generating new business, retaining customers or renewing contracts, our ability to maintain or increase premiums written or the ability to sell our products could be adversely impacted.
Determining competitive position is complicated in the auto and homeowners insurance business as companies use different underwriting standards to accept new customers and quotes and close rates can fluctuate across companies and locations.  Pricing of products is driven by multiple factors, including loss expectations, expense structure and dissimilar return targets.  Additionally, sophisticated pricing algorithms make it difficult to determine what price potential customers would pay across competitors.
There is also significant competition for producers, such as exclusive and independent agents and their licensed sales professionals. Growth and retention may be materially affected if we are unable to attract and retain effective producers or if those producers are unable to attract and retain their licensed sales professionals or customers. Similarly, growth and retention may be impacted if customer preferences change and we are unable to effectively adapt our business model and processes.
Our business could also be affected by technological changes, such as autonomous or partially autonomous vehicles or technologies that facilitate ride, car or home sharing. Such changes could disrupt the demand for products from current customers, create coverage issues, impact the frequency or severity of losses, or reduce the size of the automobile insurance market causing our auto insurance business to decline. Since auto insurance constitutes a significant portion of our overall business, we may be more sensitive than other insurers and more adversely affected by trends that could decrease auto insurance rates or reduce demand for auto insurance over time.
Technological advancements and innovation are occurring in distribution, underwriting, claims and operations at a rapid pace that may continue to accelerate. Nontraditional competitors could enter the insurance market and further accelerate these trends. Innovations must be implemented in compliance with applicable insurance regulations and may require extensive modifications to our systems and processes and extensive coordination with and reliance on the systems of third parties. If we are unable to adapt to or bring such advancements and innovations to market, the quality of our products, our relationships with customers and agents, competitive position and business prospects may be materially affected. Changes in technology related to collection and analysis of data regarding customers could expose us to regulatory or legal actions and may have a material adverse effect on our business, reputation, results of operations and financial condition.
Technology and customer preference changes may impact the ways in which we interact, do business with our customers and design our products. We may not be able to respond effectively to these changes, which could have a material effect on our results of operations and financial condition.
Our ability to adequately and effectively price our products and services is affected by the evolving nature of consumer needs and preferences, market and regulatory dynamics, broader use of telematics-based rate segmentation and potential reduction in consumer demand.
Many voluntary benefits contracts are renewed annually. There is a risk that employers may be able to obtain more favorable terms from competitors than they could by renewing coverage with us. These competitive pressures may adversely affect the renewal of these contracts, as well as our ability to sell products.
Transformative Growth may not be effectively implemented
Transformative Growth is intended to accelerate growth by expanding customer access, improving customer value and investing in marketing and technology.  The strategy encompasses all aspects of Allstate’s customer experience and business model, spanning product distribution and sales, operations and servicing, and claims processing. If the strategy is not implemented effectively, customer retention and policy growth objectives could be adversely impacted. Lost business opportunities may result due to slower than anticipated speed to market.  External forces including competitor actions or regulatory changes may also have an adverse effect on the value generated from the transformation.
Our catastrophe management strategy may adversely affect premium growth
Catastrophe risk management actions have negatively impacted the size of our homeowners business and customer retention, including customers with auto and other personal lines products and may negatively impact future sales if further actions are
The Allstate Corporation 25

2020 Form 10-K Part I - Item 1A. Risk Factors and Other Disclosures

taken. Adjustments to our business structure, size and underwriting practices in markets with significant severe weather and catastrophe risk exposure could adversely impact premium growth rates and retention.
The ability of our subsidiaries to pay dividends may affect our liquidity and ability to meet our obligations
The Allstate Corporation is a holding company with no significant operations. Its principal assets are the stock of its subsidiaries and its directly held cash and investment portfolios. Its liabilities include debt and pension and other postretirement benefit obligations related to Allstate Insurance Company employees. State insurance regulatory authorities limit the payment of dividends by insurance subsidiaries, as described in Note 16 of the consolidated financial statements. The limitations are based on statutory income and surplus. In addition, competitive pressures generally require the subsidiaries to maintain insurance financial strength ratings. These restrictions and other regulatory requirements may affect the ability of subsidiaries to make dividend payments. Limits on the ability of the subsidiaries to pay dividends could adversely affect holding company liquidity, including the ability to pay dividends to shareholders, service debt or complete share repurchase programs as planned.
Changes in regulatory capital requirements could decrease deployable capital and potentially reduce future dividends paid by our insurance companies.
ALL-20201231_G16.JPG For a discussion of capital requirements, including a potential change to a group capital calculation, see Regulation section, Limitations on Dividends by Insurance Subsidiaries.
Our ability to pay dividends or repurchase stock is subject to limitations under terms of certain of our securities
The terms of the outstanding subordinated debentures 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.
We are prohibited from declaring or paying dividends on our Series G preferred stock if we fail to meet specified capital adequacy, net income or shareholders’ equity levels. The prohibition is subject to an exception permitting us to declare dividends out of the net proceeds of common stock issued by us during the 90 days before the date of declaration even if we fail to meet such levels.
If the full preferred stock dividends for all preceding dividend periods have not been declared and paid, we generally may not repurchase or pay dividends on common stock during any dividend period while our preferred stock is outstanding.
ALL-20201231_G16.JPG See Note 12 of the consolidated financial statements.
Reinsurance may be unavailable at current levels and prices, which may limit our ability to write new business
Market conditions beyond our control impact the availability and cost of the reinsurance we purchase. Reinsurance may not remain continuously available to us to the same extent and on the same terms and rates as is currently available. Our ability to economically justify reinsurance to reduce our catastrophe risk in designated areas may depend on our ability to adjust premium rates to fully or partially recover cost. If we cannot maintain our current level of reinsurance or purchase new reinsurance protection in amounts we consider sufficient at acceptable prices, we would have to either accept an increase in our catastrophe exposure, reduce our insurance exposure or seek other alternatives.
Reinsurance subjects us to counterparty risk and may not be adequate to protect us against losses arising from ceded insurance
Collecting from reinsurers is subject to uncertainty arising from factors that include:
Whether reinsurers, their affiliates or certain indemnitors have the financial capacity and willingness to make payments under the terms of a reinsurance treaty or contract
Whether insured losses meet the qualifying conditions of the reinsurance contract
Our inability to recover from a reinsurer could have a material effect on our results of operations and financial condition.
Disruption, volatility or uncertainty in the insurance linked securities market may decrease our ability to access such market on favorable terms or at all.
Acquisitions or divestitures of businesses may not produce anticipated benefits, resulting in operating difficulties, unforeseen liabilities or asset impairments
The ability to achieve certain anticipated financial benefits from the acquisition of National General or other businesses depends in part on our ability to successfully grow and integrate the businesses consistent with our anticipated acquisition economics. Financial results could be adversely affected by unanticipated performance issues, unforeseen liabilities, transaction-related charges, diversion of management time and resources to acquisition integration challenges or growth strategies, loss of key employees, challenges in integrating information technology systems of acquired companies with our own, amortization of expenses related to intangibles, charges for impairment of long-term assets or goodwill and indemnifications.

Acquired businesses may not perform as projected, cost savings anticipated from the acquisition may not materialize, and costs associated with the integration may be greater than anticipated. As a result, if we do not manage these transitions effectively, the quality of our products as well as our relationships with customers and partners may result in the company not achieving returns on its investment at the level projected at acquisition.
26 www.allstate.com

                     Part I - Item 1A. Risk Factors and Other Disclosures 2020 Form 10-K
We also may divest businesses from time to time, including the pending sale of ALIC and certain affiliates. These transactions may result in continued financial involvement in the divested businesses, such as through reinsurance, guarantees or other financial arrangements, following the transaction. If the acquiring companies do not perform under the arrangements, our financial results could be negatively impacted.
We may be subject to the risks and costs associated with intellectual property infringement, misappropriation and third-party claims
We rely on a combination of contractual rights and copyright, trademark, patent and trade secret laws to establish and protect our intellectual property. Third parties may infringe or misappropriate our intellectual property. We may have to litigate to enforce and protect intellectual property and to determine its scope, validity or enforceability, which could divert significant resources and prove unsuccessful. An inability to protect intellectual property or an inability to successfully defend against a claim of intellectual property infringement could have a material effect on our business.
We may be subject to claims by third parties for patent, trademark or copyright infringement or breach of usage rights. Any such claims and any resulting litigation could result in significant expense and liability. If third-party providers or we are found to have infringed a third-party intellectual property right, either of us could be enjoined from providing certain products or services or from utilizing and benefiting from certain methods, processes, copyrights, trademarks, trade secrets or licenses. Alternatively, we could be required to enter into costly licensing arrangements with third parties or implement costly work-arounds. Any of these scenarios could have a material effect on our business and results of operations.
ALL-20201231_G21.JPG
Macro, regulatory and risk environment
Conditions in the global economy and capital markets could adversely affect our business and results of operations
Global economic and capital market conditions could adversely impact demand for our products, returns on our investment portfolio and results of operations. The conditions that would have the largest impact on our business include:
Low or negative economic growth
Sustained low interest rates
Rising inflation increasing claims and claims expense
Substantial increases in delinquencies or defaults on debt
Significant downturns in the market value or liquidity of our investment portfolio
Reduced consumer spending and business investment
Stressed conditions, volatility and disruptions in global capital markets or financial asset classes could adversely affect our investment portfolio.
Adverse capital and credit market conditions may significantly affect our ability to meet liquidity needs or obtain credit on acceptable terms
In periods of extreme volatility and disruption in the capital and credit markets, liquidity and credit capacity may be severely restricted. Our access to additional financing depends on a variety of factors such as market conditions, the general availability of credit, the overall availability of credit to our industry, our credit ratings and credit capacity, as well as lenders’ perception of our long- or short-term financial prospects. In such circumstances, our ability to obtain capital to fund operating expenses, financing costs, capital expenditures or acquisitions may be limited, and the cost of any such capital may be significant.
A large-scale pandemic, the occurrence of terrorism, military actions, social unrest or other actions may have an adverse effect on our business
A large-scale pandemic, such as the Coronavirus and its impacts, the occurrence of terrorism, military actions, social unrest or other actions, may result in loss of life, property damage, and disruptions to commerce and reduced economic activity. Some of the assets in our investment portfolio may be adversely affected by declines in the equity markets, changes in interest rates, reduced liquidity and economic activity caused by a large-scale pandemic. Additionally, a large-scale pandemic or terrorist act could have a material effect on sales, liquidity and operating results.
The Coronavirus resulted in governments worldwide enacting emergency measures to combat the spread of the virus. These measures, which have included the implementation of travel restrictions, government-imposed shelter-in-place orders, quarantine periods, social distancing, and restrictions on large gatherings, have caused material disruption to businesses globally, resulting in increased unemployment, a recession and increased economic uncertainty. Additionally, there is no way of predicting with certainty how long the pandemic might last, including the potential for restrictions being restored or new restrictions being implemented that could result in further economic volatility.
The Coronavirus has affected our operations and depending on its length and severity may continue to significantly affect our results of operations, financial condition and liquidity, including:
Sales of new and retention of existing policies
Shared economy demand
Claim severity costs, driving behavior and auto accident frequency
Life insurance mortality, hospital and outpatient claim costs and annuity reserves
Investment valuations and returns
Bad debt and credit allowance exposure

ALL-20201231_G16.JPG See MD&A, Highlights for a summary of the impacts of the Coronavirus on our operations, each of our segments and investments that may continue, emerge, evolve or accelerate into 2021.
The failure in cyber or other information security controls, as well as the occurrence of events unanticipated in our disaster recovery processes and business continuity planning, could result in a loss or disclosure of confidential information, damage to our reputation, additional costs and impair our ability to conduct business effectively
We depend heavily on computer systems, mathematical algorithms and data to perform necessary business functions. There are threats that could impact our ability to protect our data and systems; if the threats are successful, they could impact confidentiality, integrity and availability:
Confidentiality — protecting our data from disclosure to unauthorized parties
Integrity — ensuring data is not changed accidentally or without authorization and is accurate
Availability — ensuring our data and systems are accessible to meet our business needs
We collect, use, store or transmit a large amount of confidential, proprietary and other information (including personal information of customers, claimants or employees) in connection with the operation of our business. Systems are subject to increased attempted cyberattacks and unauthorized access, such as physical and electronic break-ins or unauthorized tampering.
We constantly defend against threats to our data and systems, including malware and computer virus attacks, unauthorized access, system failures and disruptions. Events like these could jeopardize the information processed and stored in, and transmitted through, our computer systems and networks, or otherwise cause interruptions or malfunctions in our operations, which could result in damage to our reputation, financial losses, litigation, increased costs, regulatory penalties or customer dissatisfaction.
These risks may increase in the future as threats become more sophisticated and we continue to expand internet and mobile strategies, develop additional remote connectivity solutions to serve our employees and customers, develop and expand products and services designed to protect customers’ digital footprint, and build and maintain an integrated digital enterprise.
Our increased use of third-party services (e.g., cloud technology and software as a service) can make it more difficult to identify and respond to cyberattacks in any of the above situations. Although we may review and assess third-party vendor cyber security controls, our efforts may not be successful in preventing or mitigating the effects of such events. Third parties to whom we outsource certain functions are also subject to cybersecurity risks.
Personal information is subject to an increasing number of federal, state, local and international laws and regulations regarding privacy and data security, as well as contractual commitments. Any failure or perceived failure by us to comply with such obligations may result in governmental enforcement actions and fines, litigation or public statements against us by consumer advocacy groups or others and could cause our employees and customers to lose trust in us, which could have an adverse effect on our reputation and business.
ALL-20201231_G16.JPG See the Regulation section, Privacy Regulation and Data Security, for additional information.
The occurrence of a disaster, such as a natural catastrophe, pandemic, industrial accident, blackout, terrorist attack, war, cyberattack, computer virus, insider threat, unanticipated problems with our disaster recovery processes, or a support failure from external providers, could have an adverse effect on our ability to conduct business and on our results of operations and financial condition, particularly if those events affect our computer-based data processing, transmission, storage, and retrieval systems or destroy data. If a significant number of employees were unavailable in the event of a disaster, our ability to effectively conduct business could be severely compromised. Our systems are also subject to compromise from internal threats.
Losses from changing climate and weather conditions may adversely affect our financial condition, profitability or cash flows
Climate change may affect the occurrence of certain natural events, such as an increase in the frequency or severity of wind, tornado, hailstorm and thunderstorm events due to increased convection in the atmosphere. There could also be more frequent wildfires in certain geographies, more flooding and the potential for increased severity of hurricanes due to higher sea surface temperatures. As a result, incurred losses from such events and the demand, price and availability of reinsurance coverages for automobile and homeowners insurance may be affected.
Climate change may also impact insurability by impairing our ability to identify and quantify potential hazards that will result in losses and offer our customers products at an affordable price.  Our investment portfolio is also subject to the effects of climate change as economic shifts alter the return dynamic of long-term investments and reduce valuations.
Due to significant variability associated with future changing climate conditions, we are unable to predict the impact climate change will have on our businesses.
We are subject to extensive regulation, and potential further restrictive regulation may increase operating costs and limit growth
Many of our affiliates operate in the highly regulated insurance and broader financial services sector and are subject to extensive laws and regulations that are complex and subject to change.
28 www.allstate.com

                     Part I - Item 1A. Risk Factors and Other Disclosures 2020 Form 10-K
Changes may lead to additional expenses, increased legal exposure, or increased reserve or capital requirements limiting our ability to grow or to achieve targeted profitability. Moreover, laws and regulations are administered and enforced by governmental authorities that exercise interpretive latitude, including:
State insurance regulators
State securities administrators
State attorneys general
Federal agencies including the SEC, the Financial Industry Regulatory Authority, the Department of Labor, the U.S. Department of Justice and the National Labor Relations Board
Consequently, compliance with one regulator’s or enforcement authority’s interpretation of a legal issue may not result in compliance with another’s interpretation of the same issue.
In addition, there is risk that one regulator’s or enforcement authority’s interpretation of a legal issue may change to our detriment. There is also a risk that changes in the overall legal environment may cause us to change our views regarding the actions we need to take from a legal risk management perspective. This could necessitate changes to our practices that may adversely impact our business. In some cases, state insurance laws and regulations are generally intended to protect or benefit purchasers or users of insurance products, not holders of securities that we issue. These laws and regulations may limit our ability to grow or to improve the profitability of our business.
A regulatory environment that requires rate increases to be approved, can dictate underwriting practices and mandate participation in loss sharing arrangements may adversely affect results of operations and financial condition
Political events and positions can affect the insurance market, including efforts to suppress rates to a level that may not allow us to reach targeted levels of profitability. Regulatory challenges to rate increases may restrict rate changes that may be required to achieve targeted levels of profitability and returns on equity. If we are unsuccessful, our results of operations could be negatively impacted.    
In addition, certain states have enacted laws that require an insurer conducting business in that state to participate in assigned risk plans, reinsurance facilities and joint underwriting associations. Certain states also require the insurer to offer coverage to all consumers, often restricting an insurer’s ability to charge the price it might otherwise charge for the risk acceptance. In these markets, we may be compelled to underwrite significant amounts of business at lower-than-desired rates, possibly leading to an unacceptable return on equity. Alternatively, as the facilities recognize a financial deficit, they could have the ability to assess participating insurers, adversely affecting our results of operations and financial condition. Laws and regulations of many states also limit an insurer’s ability to withdraw from one or more lines of insurance, except pursuant to a plan that is approved by the state
insurance department. Certain states require an insurer to participate in guaranty funds for impaired or insolvent insurance companies. These funds periodically assess losses against all insurance companies doing business in the state. Our results of operations and financial condition could be adversely affected by any of these factors.
Regulatory reforms, and the more stringent application of existing regulations, may make it more expensive for us to conduct our business
The federal government has enacted comprehensive regulatory reforms for financial services entities. As part of a larger effort to strengthen the regulation of the financial services market, certain reforms are applicable to the insurance industry.
The Federal Insurance Office (“FIO”) and Financial Stability Oversight Council have been established, and the federal government may enact reforms that affect the state insurance regulatory framework. The potential impact of state or federal measures that change the nature or scope of insurance and financial regulation is uncertain but may make it more expensive for us to conduct business and limit our ability to grow or achieve profitability.
We have business process and information technology operations in Canada, India and the United Kingdom that are subject to operating, regulatory and political risks in those countries. We may incur substantial costs and other negative consequences if any of these occur, including an adverse effect on our business, results of operations and financial condition.
Losses from legal and regulatory actions may be material to our results of operations, cash flows and financial condition
We are involved in various legal actions, including class-action litigation challenging a range of company practices and coverage provided by our insurance products, some of which involve claims for substantial or indeterminate amounts. We are also involved in various regulatory actions and inquiries, including market conduct exams by state insurance regulatory agencies. In the event of an unfavorable outcome in any of these matters, the ultimate liability may be more than amounts currently accrued or disclosed in our reasonably possible loss range and may be material to our results of operations, cash flows and financial condition.
ALL-20201231_G16.JPG See Note 14 of the consolidated financial statements.
Changes in or the application of accounting standards issued by standard-setting bodies and changes in tax laws may adversely affect our results of operations and financial condition
Our financial statements are subject to the application of accounting principles generally accepted in the United States of America, which are periodically revised, interpreted or expanded. Accordingly, we may be required to adopt new guidance or interpretations, which may have a material effect on our results of

operations and financial condition and could adversely impact financial strength ratings.
Market declines, changes in business strategies or other events impacting the fair value of goodwill or purchased intangible assets could result in an impairment charge to income
Pending changes to accounting for long-duration insurance contracts such as traditional life, life-contingent immediate annuities and certain voluntary accident and health insurance products will have a material effect on reserves and shareholders’ equity and could adversely impact financial strength ratings
Realization of our deferred tax assets assumes that we can fully utilize the deductions recognized for tax purposes; we may recognize additional tax expense if these assets are not fully utilized
New tax legislative initiatives may be enacted that may impact our effective tax rate and could adversely affect our tax positions or tax liabilities
ALL-20201231_G16.JPG See MD&A, Application of Critical Accounting Estimates and Note 2 of the consolidated financial statements for further details.
Loss of key vendor relationships or failure of a vendor to protect our data, confidential and proprietary information, or personal information of our customers, claimants or employees could adversely affect our operations
We rely on services and products provided by many vendors in the U.S. and abroad. These include vendors of computer hardware, software, cloud technology and software as a service, as well as vendors or outsourcing of services such as:
Claim adjustment or call center services
Human resource benefits management
Information technology support
Investment management services
If any vendor becomes unable to continue to provide products or services, or fails to protect our confidential, proprietary, and other information, we may suffer operational impairments and financial losses.
Our ability to attract, develop, and retain talent to maintain appropriate staffing levels and establish a successful work culture is critical to our success
Competition from within the insurance industry and from other industries, including the technology sector, for qualified employees with highly specialized knowledge in areas such as underwriting, data and analytics, technology and e-commerce, has often been intense and we have experienced increased competition in hiring and retaining employees.
Factors that affect our ability to attract and retain such employees include:
Compensation and benefits
Training and re-skilling programs
Reputation as a successful business with a culture
of fair hiring, and of training and promoting qualified employees
Recognition of and response to changing trends and other circumstances that affect employees
The unexpected loss of key personnel could have a material adverse impact on our business because of the loss of their skills, knowledge of our products and offerings and years of industry experience and, in some cases, the difficulty of promptly finding qualified replacement personnel.
Misconduct or fraudulent acts by employees, agents and third parties may expose us to financial loss, disruption of business, regulatory assessments and reputational harm
The company and the insurance industry are inherently susceptible to past and future misconduct or fraudulent activities by employees, representative agents, vendors, customers and other third parties.  These activities could include:
Fraud against the company, its employees and its customers through illegal or prohibited activities
Unauthorized acts or representations, unauthorized use or disclosure of personal or proprietary information, deception, and misappropriation of funds or other benefits

2020 Highlights
Overview
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 consolidated financial statements and related notes found under Item 8. contained herein.
A discussion of strategy, including updates to the multi-year Transformative Growth initiative, can be found in Part 1, Item 1. Business.
This section of this Form 10-K generally discusses 2020 and 2019 results and year-to-year comparisons between 2020 and 2019. Discussions of 2018 results and year-to-year comparisons between 2019 and 2018 that are not included in this Form 10-K can be found in Management’s Discussion and Analysis (“MD&A”) in Part II, Item 7 of our annual report on Form 10-K for 2019, filed February 21, 2020.
The most important factors we monitor to evaluate the financial condition and performance for our reportable segments and the Company include:
Allstate Protection: premium, policies in force (“PIF”), new business sales, policy retention, price changes, claim frequency and severity, catastrophes, loss ratio, expenses, underwriting results, and relative competitive position.
Protection Services: revenues, premium written, PIF, adjusted net income and net income.
Allstate Life: premiums and contract charges, new business sales, PIF, benefit spread, investment spread, expenses, adjusted net income and net income.
Allstate Benefits: premiums, new business sales, PIF, benefit ratio, expenses, adjusted net income and net income.
Allstate Annuities: investment spread, asset-liability matching, contract benefits, expenses, adjusted net income, net income and invested assets.
Investments: exposure to market risk, asset allocation, credit quality/experience, total return, net investment income, cash flows, realized capital gains and losses, unrealized capital gains and losses, long-term returns, and asset and liability duration.
Financial condition: liquidity, parent holding company deployable assets, financial strength ratings, operating leverage, debt levels, book value per share and return on equity.
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 Protection Services, 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”), Shelter-in-Place Payback expense, amortization of deferred policy acquisition costs (“DAC”), operating costs and expenses, restructuring and related charges and amortization or impairment of purchased intangibles, 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 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
Pension and other postretirement remeasurement gains and losses, after-tax
Valuation changes on embedded derivatives that are 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 that are not hedged, after-tax
Business combination expenses and the amortization or impairment 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 Protection Services, Allstate Life, Allstate Benefits and Allstate Annuities Segment sections of MD&A.

Subsequent event
On January 26, 2021, Allstate announced an agreement to sell Allstate Life Insurance Company (“ALIC”) and certain affiliates for $2.8 billion to Antelope US Holdings Company, an affiliate of an investment fund associated with The Blackstone Group Inc. Allstate will retain ownership of Allstate Life Insurance Company of New York (“ALNY”) while pursuing alternatives to sell or otherwise transfer risk to a third party. ALIC and certain affiliates represent approximately 80% of Allstate Life and Allstate Annuity reserves for life-contingent contract benefits and contractholder funds as of December 31, 2020 and generated net income of approximately $290 million and $470 million in 2020 and 2019, respectively. A loss on disposition estimated at $3 billion, after-tax, will be recorded in the first quarter of 2021. The ultimate amount of the loss on sale will be impacted by purchase price adjustments associated with certain pre-close transactions specified in the stock purchase agreement, changes in statutory capital and surplus prior to the closing date and the closing date equity of ALIC determined under GAAP, excluding unrealized gains and losses. The transaction is expected to close in the second half of 2021, subject to regulatory approvals and other customary closing conditions. Additional information about this transaction can be found in Allstate Life and Allstate Annuities sections of Part 1, Item 1. Business, MD&A and Note 3 of the consolidated financial statements of this report.
The Novel Coronavirus Pandemic or COVID-19 (“Coronavirus”)
The Coronavirus resulted in governments worldwide enacting emergency measures to combat the spread of the virus. These measures, which have included the implementation of travel restrictions, government-imposed shelter-in-place orders, quarantine periods, social distancing, and restrictions on large gatherings, have caused material disruption to businesses globally, resulting in increased unemployment, a recession and increased economic uncertainty. Additionally, there is no way of predicting with certainty how long the pandemic might last, including the potential for restrictions being restored or new restrictions being implemented that could result in further economic volatility.
We have been proactive in protecting the health and safety of our employees and agents, while delivering on our commitment to protect our customers. We executed business continuity plans, maximized work from home, including the use of virtual tools to allow for safe claims handling, provided financial relief to employees experiencing financial hardship, developed exposure escalation protocols and a return to office framework.
A pandemic such as the Coronavirus and its impacts are disclosed in Part 1 “Item 1A. Risk Factors’’, including the risk factors titled “A large-scale pandemic, the occurrence of terrorism, military actions, social unrest or other actions may have an adverse effect on our business” and “Conditions in the global economy and capital markets could adversely affect our business and results of operations”.
The magnitude and duration of the global pandemic and the impact of actions taken by governmental authorities, businesses and consumers, including timing of vaccine distribution, to mitigate health risks create significant uncertainty. We will continue to closely monitor and proactively adapt to developments and changing conditions. Currently, it is not possible to reliably estimate the length and severity of the pandemic or its impact to our operations, but the effects could be material.
We have continued to support our customers during the Coronavirus pandemic as we:
Provided our Shelter-in-Place Payback of over $948 million to customers in 2020, as the significant decline in the number of auto accidents contributed favorably to our underwriting results
Offered the Allstate Special Payment plan to provide more flexible payment options, including the option to delay payments
Extended auto insurance coverage to customers using their personal vehicles to deliver food, medicine and other goods for commercial purposes; coverage for these activities is typically excluded
Continued to provide prompt payments for life insurance and health claims related to Coronavirus
Offered free Allstate Identity Protection to U.S. residents through December 31, 2020, regardless of whether they were already Allstate customers
Increased the utilization of virtual tools such as QuickFoto Claim® and Virtual Assist® to allow for a simple, fast and safe claims handling process for customers and our employees
The following sections summarize the potential impacts of the Coronavirus on our operations, each of our segments and investments that may continue, emerge, evolve or accelerate in 2021. This list is not inclusive of all potential impacts and should not be treated as such. Within the MD&A we have included further disclosures related to the impacts of the Coronavirus on our 2020 results.

ALL-20201231_G23.JPG

Consolidated net income applicable to common shareholders increased 16.7% or $783 million to $5.46 billion in 2020 compared to 2019, primarily due to higher Allstate Protection underwriting income and higher Protection Services adjusted net income, partially offset by Shelter-in-Place Payback expense, lower net realized capital gains and lower net investment income.

Net Investment Income
($ in millions)
ALL-20201231_G25.JPG
Net investment income decreased 9.7% to $2.85 billion in 2020 compared to 2019, primarily due to a decline in market-based income driven by lower interest-bearing portfolio yields and lower performance-based results, primarily from limited partnerships.

Segment Highlights
Allstate Protection underwriting income totaled $4.57 billion in 2020, a 56.8% increase from $2.91 billion in 2019, primarily due to lower auto non-catastrophe losses, increased premiums earned and favorable catastrophe reserve reestimates in personal lines homeowners driven by subrogation settlements, partially offset by Shelter-in-Place Payback expense and higher catastrophe losses.
Catastrophe losses were $2.81 billion in 2020 compared $2.56 billion in 2019.
Subrogation settlements Allstate recognized favorable prior year catastrophe reserve reestimates of approximately $450 million and $45 million, pre-tax, net of expenses and adjustments to reinsurance, in the third quarter of 2020 related to PG&E Corporation and Southern California Edison (together “subrogation settlements”), respectively. See Note 8 of the consolidated financial statements for additional details.
Premiums written increased 1.0% to $35.77 billion in 2020 compared to 2019.
Protection Services adjusted net income was $153 million in 2020 compared to $38 million in 2019. The improvement in 2020 was primarily due to growth of Allstate Protection Plans and improved profitability at Allstate Roadside, partially offset by investments at Allstate Identity Protection.
Total revenues increased 16.6% or $273 million to $1.92 billion in 2020 from $1.65 billion in 2019 due to Allstate Protection Plan’s growth through its U.S. retail and international channels, partially offset by declines in revenue at Allstate Roadside.
Allstate Life adjusted net income was $194 million in 2020 compared to $261 million in 2019. The decrease was primarily due to higher contract benefits due to mortality associated with the Coronavirus, partially offset by lower operating costs and expenses.
Premiums and contract charges totaled $1.34 billion in both 2020 and 2019.
Allstate Benefits adjusted net income was $96 million in 2020 compared to $115 million in 2019. The decrease was primarily due to lower premiums and higher operating costs and expenses driven by a $41 million, pre-tax, write-off of capitalized software costs associated with a billing system in the second quarter of 2020, partially offset by lower contract benefits.
Premiums and contract charges totaled $1.09 billion in 2020, a decrease of 4.5% from $1.15 billion in 2019.
Allstate Annuities adjusted net loss was $53 million in 2020 compared to adjusted net income of $10 million in 2019, primarily due to lower net investment income, partially offset by lower contract benefits.
Net investment income decreased 17.0% to $761 million in 2020 from $917 million in 2019. The decrease was primarily due to a decline in market-based income driven by lower interest-bearing portfolio yields as well as lower performance-based investment results and lower average investment balances.

Book value per diluted common share (ratio of common shareholders’ equity to total common shares outstanding and dilutive potential common shares outstanding) was $91.50 as of December 31, 2020, an increase of 25.1% from $73.12 as of December 31, 2019.
Return on average common shareholders’ equity For the twelve months ended December 31, 2020, return on common shareholders’ equity was 21.0%, a decrease of 0.7 points from 21.7% for the twelve months ended December 31, 2019, primarily due to an increase in average common shareholders’ equity, partially offset by higher net income applicable to common shareholders.
Pension and other postretirement remeasurement gains and losses We recorded pension and other postretirement remeasurement gains of $51 million in 2020, primarily related to favorable asset performance compared to the expected return on plan assets, partially offset by a decrease in the discount rate and changes in actuarial assumptions. See Note 17 of the consolidated financial statements and Application of Critical Accounting Estimates section of the MD&A for further information.
Adopted accounting standard
Effective January 1, 2020, we adopted the measurement of credit losses on financial instruments accounting standard that primarily affected mortgage loans, bank loans and reinsurance recoverables. Subsequent to the adoption, we measure credit losses on financial instruments, including losses related to mortgage loans, bank loans and reinsurance recoverables, using the expected credit loss model. This model requires us to recognize an estimate of expected credit losses for affected financial assets in a valuation allowance that when deducted from the amortized cost basis of the related financial assets results in a net carrying value at the amount expected to be collected.
See Note 2 of the consolidated financial statements for additional details on the adopted accounting standard.

Property-Liability Operations
Overview 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, amortization or impairment of purchased intangibles, restructuring and related charges and Shelter-in-Place Payback expense, less other revenue to premiums earned.
Combined ratio: 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 intangibles on combined ratio: the ratio of amortization of purchased intangibles to premiums earned.
Effect of impairment of purchased intangibles on combined ratio: the ratio of impairment of purchased intangibles to premiums earned.
Effect of restructuring and related charges on combined ratio: the ratio of restructuring and related charges to premiums earned.
Effect of Shelter-in-Place Payback expense on combined and expense ratios: the ratio of Shelter-in-Place Payback expense 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.

(1)Auto and commercial lines customers received a Shelter-in-Place Payback due to the significant declines in the number of auto accidents caused by mandated stay-at-home orders, other pandemic containment actions and reduced economic activity.
(2)As a result of the Coronavirus, we offered customers the Allstate Special Payment plan to provide more flexible payment options, including the option to delay payments, resulting in increased bad debt expense of $60 million in 2020. This increase added 0.2 points to the expense ratio in 2020.
(3)Restructuring and related charges in 2020 primarily related to Transformative Growth. See Note 13 of the consolidated financial statements for additional details.

Net investment income decreased 7.3% or $112 million in 2020 compared to 2019, due to a decline in market-based income driven by lower interest-bearing portfolio yields as well as lower performance-based investment results, mainly from limited partnerships.
