For Fiscal Year Ended December 31, 2022

PART I
Item 1.  BUSINESS
The Travelers Companies, Inc. (together with its consolidated subsidiaries, the Company) is a holding company principally engaged, through its subsidiaries, in providing a wide range of commercial and personal property and casualty insurance products and services to businesses, government units, associations and individuals. The Company is incorporated as a general business corporation under the laws of the State of Minnesota and is one of the oldest insurance organizations in the United States, dating back to 1853. The principal executive offices of the Company are located at 485 Lexington Avenue, New York, New York 10017, and its telephone number is (917) 778-6000. The Company also maintains executive offices in Hartford, Connecticut, and St. Paul, Minnesota. The term “TRV” in this document refers to The Travelers Companies, Inc., the parent holding company excluding subsidiaries.

PROPERTY AND CASUALTY INSURANCE OPERATIONS
The property and casualty insurance industry is highly competitive in the areas of price, service, product offerings, agent and broker relationships and other methods of distribution. Distribution methods include the use of local and national independent agents and brokers, agency aggregators and carrier-based agencies, as well as direct to consumer, affinity and other partner platforms. According to A.M. Best, there are approximately 1,100 property and casualty groups in the United States, comprising approximately 2,600 property and casualty companies. Of those groups, the top 150 accounted for approximately 94% of the consolidated industry’s total net written premiums in 2021. The Company competes with both foreign and domestic insurers. In addition, some property and casualty insurers writing commercial lines of business, including the Company, offer products for alternative forms of risk protection in addition to traditional insurance products. These products include large deductible programs and various forms of self-insurance, some of which utilize captive insurance companies and risk retention groups. The Company’s competitive position in the marketplace is based on many factors, including the following:

ability to profitably price business, retain existing customers and obtain new business;
premiums charged, contract terms and conditions, products and services offered (including the ability to design customized programs);
agent, broker and policyholder relationships;
ability to keep pace relative to competitors with changes in technology and information systems;
ability to use data and analytics to make decisions;
speed of claims payment;
ability to provide a positive customer experience;
ability to provide products and services in a cost effective manner;
ability to provide new products and services to meet changing customer needs;
ability to adapt to changes in business models, technology, customer preferences or regulation impacting the markets in which the Company operates;
perceived overall financial strength and corresponding ratings assigned by independent rating agencies;
ability to recruit and retain qualified employees;
geographic scope of business; and
local presence.

In addition, the marketplace is affected by the available capacity of the insurance industry, as measured by statutory capital and surplus, and the availability of reinsurance from both traditional sources, such as reinsurance companies and capital markets (through catastrophe bonds), and non-traditional sources, such as hedge funds and pension plans. Industry capacity as measured by statutory capital and surplus expands and contracts primarily in conjunction with profit levels generated by the industry, less amounts returned to shareholders through dividends and share repurchases. Capital raised by debt and equity offerings may also increase statutory capital and surplus.

Pricing and Underwriting
Pricing of the Company’s property and casualty insurance products is generally developed based upon an estimation of expected losses, the expenses associated with producing, issuing and servicing business and managing claims, the time value of money related to the expected loss and expense cash flows, and a reasonable profit margin that considers the capital needed to support the Company’s business. The Company has a disciplined approach to underwriting and risk management that emphasizes product returns and profitable growth over time rather than premium volume or market share. The Company’s insurance subsidiaries are subject to state laws and regulations regarding rate and policy form approvals. The applicable state laws and regulations establish standards in certain lines of business to ensure that rates are not excessive, inadequate, unfairly
3


discriminatory, or used to engage in unfair price competition. The Company’s ability to increase rates and the relative timing of the process are dependent upon each respective state’s requirements, as well as the competitive market environment.

(2)No other single state accounted for 3.0% or more of the Company’s consolidated direct written premiums written in 2022.
Catastrophe Exposure
The Company’s property and casualty insurance operations expose it to claims arising out of catastrophes. The Company uses various analyses and methods, including proprietary and third-party modeling processes, to monitor and analyze underwriting risks of business in natural catastrophe-prone areas and target risk areas for conventional terrorist attacks (defined as attacks other than nuclear, biological, chemical or radiological events). The Company relies, in part, upon these analyses to make underwriting decisions designed to manage its exposure on catastrophe-exposed business. For example, as a result of these analyses, the Company has at various times limited the writing of new property and homeowners business in some markets and has selectively taken underwriting actions on new and existing business. These underwriting actions on new and existing business include tightening underwriting standards, selective price increases and changes to policy terms specific to hurricane-, tornado-, wind-, wildfire- and hail-prone areas. See “Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations—Catastrophe Modeling” and “—Changing Climate Conditions.” The Company also utilizes reinsurance to manage its aggregate exposures to catastrophes. See “—Reinsurance.”

Principal Markets and Methods of Distribution
Business Insurance markets and distributes products through thousands of independent agencies and brokers. Agencies and brokers are serviced by 86 field offices and supported by customer service centers where the Company performs services for agents for a fee and centralized business centers where the Company processes new and renewal business that meet certain underwriting criteria.

Business Insurance builds relationships with well-established, independent insurance agencies and brokers. In selecting new independent agencies and brokers to distribute its products, Business Insurance considers, among other factors, each agency’s or broker’s financial strength, staff experience and strategic fit with the Company’s operating and marketing plans. Once an agency or broker is appointed, Business Insurance regularly monitors its performance. The majority of products offered in the United States are distributed through independent agents and brokers, many of whom also sell the Company’s Personal Insurance and Bond & Specialty Insurance products. Business Insurance continues to make significant investments to enable real-time interface capabilities with its independent agencies and brokers.

Domestic 
Select Accounts markets and distributes products and services to small businesses, generally with fewer than 50 employees, through a large network of independent agents and brokers. Products offered by Select Accounts are guaranteed-cost policies, including packaged products covering property and liability exposures.  Each small business risk is independently evaluated via an automated underwriting platform which in turn enables agents to quote, bind and issue a substantial amount of new small business risks in an efficient manner. Risks with more complex characteristics are underwritten with the assistance of Company personnel.
Middle Market markets and distributes products and services primarily to mid-sized businesses with 50 to 1,000 employees through a large network of independent agents and brokers. The Company offers a full line of products to its Middle Market customers with an emphasis on guaranteed-cost programs. Each account is underwritten based on the unique risk characteristics, loss history and coverage needs of the account. The ability to underwrite at this detailed level allows Middle Market to have a broad risk appetite and a diversified customer base. Within Middle Market, products and services are tailored to certain targeted industry segments of significant size and complexity that require unique underwriting, claims handling services, risk management or other insurance-related products and services.
6


National Accounts markets and distributes products and services to large companies through a large network of national and regional brokers. Products offered by National Accounts are primarily casualty programs that utilize loss-sensitive products, such as large deductible, and to a lesser extent, retrospectively rated insurance and self-insured retention plans. National Accounts also offers insurance-related services, such as claims administration, risk management, loss control and risk management information services through Constitution State Services LLC, a wholly-owned subsidiary of the Company. The commercial residual market business of National Accounts services approximately 38% of the total workers’ compensation assigned risk market, making the Company one of the largest servicing carriers in the industry.
National Property and Other markets and distributes products and services to a wide customer base, providing traditional and customized insurance programs to a broad range of customer sizes through a large network of agents and brokers. National Property and Other also provides insurance coverage to the excess and surplus lines market, which is characterized by the absence of regulation related to rate and form, and allows for more pricing and coverage flexibility to write certain classes of business. In working with agents or program managers on a brokerage basis, National Property and Other underwrites the business internally and sets the premium level. In working with agents or program managers with delegated underwriting authority, the agents produce and underwrite business subject to pricing and underwriting guidelines that have been specifically designed for each facility or program.
International markets and distributes products and services principally through brokers in each of the countries in which it operates. International also writes business at Lloyd’s, where its products are distributed through Lloyd’s wholesale and retail brokers. By virtue of Lloyd’s worldwide licenses, Business Insurance has access to international markets across the world.

Effective January 1, 2023, the Company entered into a quota share reinsurance agreement with subsidiaries of Fidelis Insurance Holdings Limited (Fidelis) pursuant to which the Company will assume 20% of the business written by Fidelis during 2023, subject to a loss ratio cap.  The Company’s portion of net written premiums from Fidelis is expected to be approximately $550 million to $600 million for the full year and will be reported as part of the International results of Business Insurance. The Company also has a minority investment in Fidelis.

Pricing and Underwriting
Business Insurance utilizes underwriting, claims, engineering, actuarial and product development disciplines for particular industries, together with extensive amounts of proprietary data gathered and analyzed over many years, as well as third-party data, to facilitate its risk selection process and develop pricing parameters. Business Insurance utilizes both proprietary forms and standard industry forms for the insurance policies it issues.

A portion of business in this segment, particularly in National Accounts and Construction, is written with large deductible insurance policies. Under workers’ compensation insurance contracts with large deductible features, the Company is obligated to pay the claimant the full amount of the claim. The Company is subsequently reimbursed by the contractholder for the deductible amount and, as a result, is subject to credit risk until such reimbursement is made. At December 31, 2022, contractholder payables on unpaid losses within the deductible layer of large deductible policies were approximately $3.60 billion, and the associated receivables (net of allowance for expected credit losses) were approximately $3.58 billion. Business Insurance also utilizes retrospectively rated policies for a portion of its business, primarily for workers’ compensation coverage.  Although the retrospectively rated feature of the policy substantially reduces insurance risk for the Company, it introduces additional credit risk to the Company. Premiums receivable from holders of retrospectively rated policies totaled approximately $70 million at December 31, 2022.  Significant collateral, primarily letters of credit and, to a lesser extent, cash collateral, trusts or surety bonds, is generally obtained for large deductible plans and/or retrospectively rated policies that provide for deferred collection of deductible recoveries and/or ultimate premiums. The amount of collateral requested is based upon the creditworthiness of the customer and the nature of the insured risks.  Business Insurance regularly monitors the credit exposure on individual accounts and the adequacy of collateral.   For additional information concerning credit risk in certain of the Company’s businesses, see “Item 1A—Risk Factors—We are exposed to credit risk in certain of our insurance operations and with respect to certain guarantee or indemnification arrangements that we have with third parties.”
Product Lines
Business Insurance provides the following types of coverages:

Domestic
Workers’ Compensation. Provides coverage for employers for specified benefits payable under state or federal law for workplace injuries to employees. There are typically four types of benefits payable under workers’ compensation policies:
7


medical benefits, disability benefits, death benefits and vocational rehabilitation benefits. The Company emphasizes managed care cost containment strategies, which involve employers, employees and care providers in a collaborative effort that focuses on the injured employee’s early return to work and cost-effective quality care.
Commercial Automobile. Provides coverage for businesses against losses incurred from personal bodily injury, bodily injury to third parties, property damage to an insured’s vehicle and property damage to other vehicles and other property resulting from the ownership, maintenance or use of automobiles and trucks in a business.
Commercial Property. Provides coverage for loss of or damage to buildings, inventory and equipment resulting from a variety of events, including, among others, hurricanes and other windstorms, tornadoes, earthquakes, hail, wildfires, severe winter weather, floods, volcanic eruptions, tsunamis, theft, vandalism, fires, explosions, terrorism and financial loss due to business interruption resulting from covered property damage. Commercial property also includes specialized equipment insurance, which provides coverage for loss or damage resulting from the mechanical breakdown of boilers and machinery, and ocean and inland marine insurance, which provides coverage for goods in transit and unique, one-of-a-kind exposures.
General Liability. Provides coverages for businesses against third-party claims arising from accidents occurring on their premises or arising out of their operations, including as a result of injuries sustained from products sold. Coverages may also include directors’ and officers’ liability arising in their official capacities, employment practices liability insurance, fiduciary liability for trustees and sponsors of pension, health and welfare, and other employee benefit plans, errors and omissions insurance for employees, agents, professionals and others arising from acts or failures to act under specified circumstances, cyber liability, as well as umbrella and excess insurance.
Commercial Multi-Peril.  Provides a combination of the property and liability coverages described in the foregoing product line descriptions.
The Company offers the above coverages through the following types of products and services:
guaranteed-cost insurance products, where the premiums charged are not adjusted for actual loss experience during the covered period;
loss-sensitive insurance products, including large deductible and retrospectively rated policies, where fees or premiums are adjusted based on actual loss experience of the insured during the policy period; and
service programs, which are generally sold to the Company’s National Accounts customers, where the Company receives fees rather than premiums for providing insurance-related services, such as claims administration, risk management, loss control and risk management information services.
The Company also participates in state assigned risk pools as a servicing carrier and pool participant.
International
Provides coverage for employers’ liability (similar to workers’ compensation coverage in the United States), public and product liability (the equivalent of general liability), professional indemnity (similar to professional liability coverage), commercial property, commercial automobile, marine, aviation, onshore and offshore energy, construction, terrorism, personal accident and kidnap & ransom. Marine provides coverage for ship hulls, cargoes carried, private yachts, marine-related liability, ports and terminals, and fine art. Aviation provides coverage for worldwide aviation risks, including physical damage and liabilities for airline, aerospace, general aviation, aviation war and space risks. Personal accident provides financial protection in the event of death or disablement due to accidental bodily injury, while kidnap & ransom provides financial protection against kidnap, hijack, illegal detention and extortion. While the covered hazards may be similar to those in the U.S. market, the different legal environments can make the product risks and coverage terms very different from those the Company faces in the United States.
Net Retention Policy Per Risk
The following discussion reflects the Company’s retention policy with respect to Business Insurance as of January 1, 2023. For third-party liability, Business Insurance generally limits its net retention, through the use of reinsurance, to a maximum of $14.0 million per insured, per occurrence, subject further to a significant aggregate annual deductible. For property exposures, Business Insurance generally limits its net retention, through the use of reinsurance, to a maximum amount per risk of $21.0
8


million per occurrence. Business Insurance generally retains its workers' compensation exposures. Reinsurance treaties often have aggregate limits or caps which may result in larger net per-risk retentions if the aggregate limits or caps are reached. Business Insurance utilizes facultative reinsurance to provide additional limits capacity or to reduce retentions on an individual risk basis. Business Insurance may also retain amounts greater than those described herein based upon the individual characteristics of the risk.

Competition
The insurance industry is represented in the commercial marketplace by many insurance companies of varying size as well as other entities offering risk alternatives, such as self-insured retentions or captive programs. Market competition operates within the insurance regulatory framework to set the price charged for insurance products and the levels of coverage and service provided. A company’s success in the competitive commercial insurance landscape is largely measured by its ability to profitably provide insurance and services, including claims handling and risk management, at prices and terms that retain existing customers and attract new customers, as well as its financial strength. See “Item 1A—Risk Factors—The intense competition that we face, including with respect to attracting and retaining employees, and the impact of innovation, technological change and changing customer preferences on the insurance industry and the markets in which we operate, could harm our ability to maintain or increase our business volumes and our profitability.”
Domestic
Competitors typically write Select Accounts business through independent agents and brokers and, to a lesser extent, as direct writers, including through affinity and other partner platforms. Both national (including international companies doing business in the U.S.) and regional property and casualty insurance companies compete in the Select Accounts market which generally comprises lower-hazard, “Main Street” business customers. Risks are underwritten and priced using standard industry practices and a combination of proprietary and standard industry product offerings. Competition in this market is focused on ease and speed of doing business and price.

Competitors typically write Middle Market business through independent agents and brokers. Several of Middle Market’s operations require unique combinations of industry knowledge, customized coverage, specialized risk control and loss handling services, along with partnerships with agents and brokers that also focus on these markets. Competitors in this market are
9


primarily national property and casualty insurance companies (including international companies doing business in the U.S.) that write most classes of business using traditional products and pricing, and regional insurance companies. Companies compete based on product offerings, service levels, price, claim and loss prevention services and ease and speed of doing business. Efficiency through automation and response time to agent, broker and customer needs is one key to success in this market.
In the National Accounts market, competition is based on price, product offerings, claim and loss prevention services, managed care cost containment, risk management information systems and collateral requirements. National Accounts primarily competes with national property and casualty insurance companies (including international companies doing business in the U.S.), as well as with other underwriters of property and casualty insurance in the alternative risk transfer market, such as self-insurance plans, captives managed by others, third-party administrators and a variety of other risk-financing vehicles and mechanisms. The residual market division competes for state contracts to provide claims and policy management services.

National Property and Other competes in focused target markets. Each of these markets is different and requires unique combinations of industry knowledge, customized coverage, specialized risk management and claims handling services, along with partnerships with agents and brokers that also focus on these markets. Some of these businesses compete with national carriers (including international companies doing business in the U.S.) with similarly dedicated underwriting and marketing groups, whereas others compete with smaller regional companies. Specialized agents and brokers, including wholesale agents and program managers, supplement this focused target market approach. National Property and Other’s competitive strategy typically is based on the application of focused industry knowledge to insurance and risk needs.

International
International competes with numerous international and domestic insurers in Canada, the United Kingdom and the Republic of Ireland. Companies compete on the basis of price, product offerings, distribution partnerships, the level of claim and risk management services provided and the ease and speed of doing business. The Company has developed expertise in various markets in these countries similar to those served in the United States and provides both property and casualty coverage for these markets.

At Lloyd’s, International competes with other syndicates operating in the Lloyd’s market as well as international and domestic insurers in the various markets where the Lloyd’s operation writes business worldwide, with an emphasis on short-tail insurance lines. Competition is based on price, product and service.

BOND & SPECIALTY INSURANCE
Bond & Specialty Insurance offers surety, fidelity, management liability, professional liability, and other property and casualty coverages and related risk management services to its customers, primarily in the United States, and certain surety and specialty insurance products in Canada, the United Kingdom, the Republic of Ireland and Brazil (through a joint venture as described below), in each case utilizing various degrees of financially-based underwriting approaches.  The range of coverages includes performance, payment and commercial surety bonds for construction and general commercial enterprises; management liability coverages including directors’ and officers’ liability, employment practices liability, fidelity liability, fiduciary liability and cyber risk for public corporations, private companies, not-for-profit organizations and financial institutions; professional liability coverage for a variety of professionals including, among others, lawyers and design professionals; in the United States only, property, workers’ compensation, auto and general liability for financial institutions; and transactional liability coverages to public and private companies.

Bond & Specialty Insurance's surety business in Brazil and Colombia is conducted through Junto Holding Brasil S.A. (Junto) and Junto Holding Latam S.A. in Brazil. The Company owns 49.5% of both Junto, a market leader in surety coverages in Brazil, and Junto Holding Latam S.A., which owns a majority interest in JMalucelli Travelers Seguros S.A., a Colombian surety provider. These joint venture investments are accounted for using the equity method and are included in “other investments” on the consolidated balance sheet.

Principal Markets and Methods of Distribution

Bond & Specialty Insurance markets and distributes the vast majority of its products in the United States through many of the same independent agencies and brokers that distribute Business Insurance’s products in the United States. Bond & Specialty Insurance builds relationships with well-established, independent insurance agencies and brokers. In selecting new independent agencies and brokers to distribute its products, Bond & Specialty Insurance considers, among other factors, each agency’s or broker’s profitability, financial stability, staff experience and strategic fit with its operating and marketing plans. Once an agency or broker is appointed, its ongoing performance is regularly monitored. Bond & Specialty Insurance continues to make investments to enable real-time interface capabilities with its independent agencies and brokers.

Pricing and Underwriting
Bond & Specialty Insurance utilizes underwriting, claims, engineering, actuarial and product development disciplines for specific accounts and industries, together with extensive amounts of proprietary data gathered and analyzed over many years, as well as third-party data, to facilitate its risk selection process and develop pricing parameters. Bond & Specialty Insurance utilizes both proprietary forms and standard industry forms for the insurance policies and bonds it issues.

Product Lines
Bond & Specialty Insurance writes the following types of coverages:
Domestic
Fidelity and Surety. Provides fidelity insurance coverage, which protects an insured for loss due to embezzlement or misappropriation of funds by an employee, and surety, which is a three-party agreement whereby the surety company agrees to pay a third party or to complete an obligation in response to the default, acts or omissions of a bonded party. Surety bonds are generally provided for construction performance; legal matters, such as appeals; trustees in bankruptcy and probate; and other performance obligations.

General Liability. Provides coverage for specialized liability exposures as described above in more detail in the “Business Insurance” section of this report, as well as transactional liability coverages.

Other. Coverages include Commercial Property, Workers’ Compensation, Commercial Automobile and Commercial Multi-Peril, which are described above in more detail in the “Business Insurance” section of this report.

International
Fidelity and Surety and certain General Liability products are provided internationally to various customer groups.

Net Retention Policy Per Risk
The following discussion reflects the Company’s retention policy with respect to Bond & Specialty Insurance as of January 1, 2023. For management liability coverages, including but not limited to directors’ and officers’ liability, professional liability, employment practices liability, fidelity liability, fiduciary liability and cyber risk liability, Bond & Specialty Insurance generally limits net retentions to $25.0 million per policy. For surety, where limits are often significant, Bond & Specialty Insurance generally retains up to $132.5 million probable maximum loss (PML) per principal, after reinsurance, but may retain higher amounts based on the type of obligation, credit quality and other credit risk factors. Reinsurance treaties often have
11


aggregate limits or caps which may result in larger net per risk retentions if the aggregate limits or caps are reached. Bond & Specialty Insurance utilizes facultative reinsurance to provide additional limits capacity or to reduce retentions on an individual risk basis. Bond & Specialty Insurance may also retain amounts greater than those described herein based upon the individual characteristics of the risk.

Competition
The competitive landscape in which Bond & Specialty Insurance operates is affected by many of the same factors described above for Business Insurance. Competitors in this market are primarily national property and casualty insurance companies (including international companies doing business in the U.S.) that write most classes of business and, to a lesser extent, regional insurance companies and companies that have developed niche programs for specific industry segments.

Domestic
Bond & Specialty Insurance underwrites and markets its products to all sizes of businesses and other organizations, as well as individuals. The Company believes that its reputation for timely and consistent decision making and financial stability, a nationwide network of local underwriting, claims and industry experts and strong producer and customer relationships, as well as its ability to offer its customers a full range of products and services, provides Bond & Specialty Insurance an advantage over many of its competitors and enables it to compete effectively in a complex, dynamic marketplace. The Company believes that the ability of Bond & Specialty Insurance to cross-sell its products to customers of Business Insurance and Personal Insurance also provides the Company with a competitive advantage. See “Item 1A—Risk Factors—The intense competition that we face, including with respect to attracting and retaining employees, and the impact of innovation, technological change and changing customer preferences on the insurance industry and the markets in which we operate, could harm our ability to maintain or increase our business volumes and our profitability.”

International
International competes with numerous international and domestic insurers in Canada, the United Kingdom, the Republic of Ireland, and in Brazil and Colombia through joint ventures. Companies compete on the basis of price, product offerings, the
12


level of claim and risk management services provided, the ease and speed of doing business and stability of the insurer. The Company has developed expertise in various markets in these countries similar to those served in the United States and provides certain specialty coverages for these markets.

PERSONAL INSURANCE
Personal Insurance offers a broad range of property and casualty insurance products and services covering individuals’ personal risks, primarily in the United States, as well as in Canada.

Principal Markets and Methods of Distribution
Domestic 
Personal Insurance products are marketed and distributed primarily through thousands of independent agents and brokers located throughout the United States, supported by personnel in eight sales regions. In addition, sales and service are provided to customers through five contact centers. Principal markets for Personal Insurance products are spread throughout the contiguous United States.

In selecting new independent agencies to distribute its products, Personal Insurance considers many factors, including financial stability, staff experience, customer facing online and digital capabilities and operating and marketing plans. Once an agency is appointed, Personal Insurance regularly monitors its performance.

Agents can access the Company’s agency service portal for a number of resources, including customer service, marketing and claims management. In addition, agencies can choose to shift the ongoing service responsibility for Personal Insurance’s customers to the Company’s Customer Care Program, where the Company provides, on behalf of an agency, a comprehensive array of customer service needs, including billing inquiries, coverage discussions and account changes. Approximately two thousand agents take advantage of this service alternative, for which they generally pay a fee.

Personal Insurance also markets and distributes its products directly to consumers, largely through digital marketing, and additional channels, including corporations that make the Company’s product offerings available to their employees primarily through payroll deductions, consumer associations and affinity groups. Personal Insurance handles the sales and service for these programs either through a sponsoring independent agent or through the Company’s contact center locations. Personal Insurance also markets and distributes its products on other distribution platforms, including carrier partnerships. Since 1995, the Company has had a distribution agreement with the agency affiliate of GEICO to underwrite a portion of their homeowners business.

International
In Canada, the Company markets and distributes its personal insurance products principally through hundreds of brokers located throughout the country.

Pricing and Underwriting
Personal Insurance has developed a product management methodology that integrates the disciplines of underwriting, claims, actuarial and product development. This approach is designed to maintain high-quality underwriting discipline and pricing segmentation. Proprietary and third-party data accumulated over many years is analyzed, and Personal Insurance uses a variety of risk differentiation models to facilitate its pricing segmentation and underwriting. The Company’s product management area establishes underwriting guidelines integrated with its filed pricing and rating plans, which enable Personal Insurance to effectively execute its risk selection and pricing processes.

Domestic
Pricing for personal automobile insurance is driven in large part by changes in the frequency of claims and changes in severity, including inflation in the cost of automobile replacements and repairs (including parts and labor), medical care and resolution of liability claims. Pricing in the homeowners business is driven in large part by changes in the frequency of claims and changes in severity, including inflation in the cost of materials, labor and household possessions. In addition to the normal risks associated with any multiple peril coverage, the profitability and pricing of both homeowners and automobile insurance are affected by the incidence of catastrophes and other weather-related events, as well as other unusual circumstances, such as the impact of supply chain disruptions, labor shortages and inflation. Insurers writing personal lines property and casualty policies may be unable to change prices until some time after the costs associated with coverage have changed, primarily because of state insurance rate regulation. The pace at which an insurer can change rates in response to changing costs depends, in part, on whether the applicable state law requires prior approval of rate changes or notification to the regulator either before or after a rate change is imposed. In states with prior approval laws, rates must be approved by the regulator before being used by the insurer. In states having “file-and-use” laws, the insurer must file rate changes with the regulator, but does not need to wait for approval before using the new rates. A “use-and-file” law requires an insurer to file rates within a period of time after the insurer begins using the new rate. Approximately one-half of the states require prior approval of most rate changes. In addition, changes to methods of marketing and underwriting in some jurisdictions are subject to state-imposed restrictions, which can make it more difficult for an insurer to significantly manage catastrophe exposures.

The Company’s ability or willingness to change prices, modify underwriting terms or reduce exposure to certain geographies may be limited due to a number of factors, including public policy, the competitive environment, the evolving political and legislative environment and/or changes in the general economic climate. The Company also may choose to write business it might not otherwise write in some states for strategic purposes, such as improving access to other commercial or personal underwriting opportunities. In choosing to write business in some states, the Company also considers the costs and benefits of those states’ residual markets and guaranty funds, as well as other property and casualty business the Company writes in those states.

International
Pricing and underwriting for personal automobile and homeowners insurance in Canada is driven in large part by the same factors as in the United States. For personal automobile insurance, all provinces in Canada require prior approval before rates are implemented.

Product Lines
Domestic
The primary coverages in Personal Insurance are personal automobile and homeowners and other insurance sold to individuals.  Personal Insurance had approximately 9.2 million active policies (i.e., policies-in-force) in the United States at December 31, 2022.
Personal Insurance writes the following types of coverages:
Automobile provides coverage for liability to others for both bodily injury and property damage, uninsured motorist protection, and for physical damage to an insured’s own vehicle from collision, fire, flood, hail and theft. In addition, many states require policies to provide first-party personal injury protection, frequently referred to as no-fault coverage.

Homeowners and Other provides protection against losses to dwellings and contents from a variety of perils (excluding flooding) as well as coverage for personal liability. The Company writes homeowners insurance for dwellings,
14


condominiums and tenants, and rental properties. The Company also writes coverage for boats and yachts, valuable personal items such as jewelry, umbrella liability, and weddings and special events.
International
International provides automobile and homeowners and other coverages in Canada (similar to coverages in the United States).  Personal Insurance had approximately 449,000 active policies in Canada at December 31, 2022.
Net Retention Policy Per Risk
The following discussion reflects the Company’s retention policy with respect to Personal Insurance as of January 1, 2023. Personal Insurance generally retains its primary personal auto exposures in their entirety. For personal property insurance, there is an $8.0 million maximum retention per risk, net of reinsurance. Personal Insurance uses facultative reinsurance to provide additional limits capacity or to reduce retentions on an individual risk basis. Personal Insurance issues umbrella policies up to a maximum limit of $10.0 million per risk. Personal Insurance may also retain amounts greater than those described herein based upon the individual characteristics of the risk.

Competition
Domestic
Although national companies (including international companies doing business in the U.S.) write the majority of this business, Personal Insurance also faces competition from many regional and local companies. Competitors write business in both traditional and alternative distribution platforms through independent agents and as direct writers, either through the use of exclusive agents, salaried employees or direct marketing strategies. Personal Insurance primarily competes based on breadth of product offerings, price, service (including claims handling), partner and customer experience, stability of the insurer and name recognition. In the independent agent channel, Personal Insurance competes for business within each independent agency since these agencies also offer policies from competing companies. Most independent personal insurance agents utilize price comparison rating technology, sometimes referred to as “comparative raters,” as a cost-efficient means of obtaining quotes from multiple companies. Because the use of this technology facilitates the process of generating multiple quotes, the technology has increased price comparison on new and renewal business.

International
Personal Insurance competes with numerous international and domestic insurers in Canada. Companies compete based on similar factors to those described above for domestic operations. The Company has developed expertise in various markets in Canada similar to those served in the United States and provides both automobile and homeowners and other coverages for this market.

See “Item 1A—Risk Factors—The intense competition that we face, including with respect to attracting and retaining employees, and the impact of innovation, technological change and changing customer preferences on the insurance industry and the markets in which we operate, could harm our ability to maintain or increase our business volumes and our profitability.”

CLAIMS MANAGEMENT
The Company’s claim functions are managed through its Claims Services organization, with locations in the United States and in the other countries where it does business. With approximately 13,000 employees, Claims Services employs a group of professionals with diverse skills, including claim adjusters, appraisers, attorneys, investigators, engineers, accountants, nurses, data and analytics professionals, system specialists and training, management and support personnel. Approved external service providers, such as investigators, attorneys and, when necessary, independent adjusters and appraisers, are available for use as appropriate.

United States field claim management teams located in 16 claim centers and 55 satellite and specialty-only offices in 42 states are organized to maintain focus on the specific claim characteristics unique to the businesses within the Company’s business segments. Claim teams with specialized skills, required licenses, resources and workflows are matched to the unique exposures of those businesses, with local claims management dedicated to achieving optimal results within each segment, including acting as a third party administrator for large customers who self-insure and retain the Company to handle their claims process on a fee-for-service basis. The Company’s home office operations provide additional support in the form of workflow design, quality management, information technology, advanced management information and data analysis, training, financial reporting and control, and human resources strategy. This structure permits the Company to maintain the economies of scale of a large, established company while retaining the agility to respond promptly to the needs of customers, brokers, agents and underwriters. Claims management for International, while generally provided locally by staff in the respective international locations due to local knowledge of applicable laws and regulations, is also managed by the Company’s Claims Services organization in the United States to leverage that knowledge base and to share best practices.

An integral part of the Company’s strategy to benefit customers and shareholders is its continuing industry leadership in the fight against insurance fraud through its Investigative Services unit. The Company has a nationwide staff of experts who investigate a wide array of insurance fraud schemes using in-house forensic resources and other technological tools. This staff also has specialized expertise in fire scene examinations, medical provider fraud schemes, law firm fraud schemes and data mining. The Company also dedicates investigative resources to ensure that violations of law are reported to and prosecuted by law enforcement agencies.

Claims Services uses technology, management information and data analysis to assist the Company in reviewing its claim practices and results in order to evaluate and improve its claims management performance. The Company’s claims-management strategy is focused on segmentation of claims and appropriate technical specialization to drive effective claim resolution. The Company regularly monitors its investment in claim resources to maintain an effective focus on claim outcomes and a
16


disciplined approach to continual improvement. The Company operates a state-of-the-art claims-training facility which offers hands-on experiential learning to help ensure that its claim professionals are properly trained. In recent years, the Company has invested significant additional resources in many of its claims handling operations, including digital, analytics, artificial intelligence and automation capabilities, and regularly monitors the effect of those investments to ensure a consistent optimization among outcomes, cost and service.

Claims Services’ catastrophe response strategy is to respond to a significant catastrophic event using its own personnel, enabling it to minimize reliance on independent adjusters and appraisers. The Company has developed a large dedicated catastrophe response team and trained a large Enterprise Response Team of existing employees who can be deployed on short notice in the event of a catastrophe that generates claim volume exceeding the capacity of the dedicated catastrophe response team. In recent years, these internal resources were successfully deployed to respond to a significant level of catastrophe claims.

REINSURANCE
The Company reinsures a portion of the risks it underwrites in order to manage its exposure to losses and to protect its capital. The Company cedes to reinsurers a portion of these risks and pays premiums based upon the risk and exposure of the policies subject to such reinsurance. The Company utilizes a variety of reinsurance agreements to manage its exposure to large property and casualty losses, including facultative as well as catastrophe and individual risk treaties. Ceded reinsurance involves credit risk, except with regard to mandatory pools and associations, and is predominantly subject to aggregate loss limits. Although the reinsurer is liable to the Company to the extent of the reinsurance ceded, the Company remains liable as the direct insurer on all risks reinsured. Reinsurance recoverables are reported after reductions for known insolvencies and after allowances for uncollectible amounts. The Company also holds collateral, including trust agreements, escrow funds and letters of credit, under certain reinsurance agreements. The Company monitors the financial condition of reinsurers on a regular basis and reviews its reinsurance arrangements periodically. Reinsurers are selected based on their financial condition, business practices, the price of their product offerings and the value of collateral provided. After reinsurance is purchased, the Company has limited ability to manage the credit risk of a reinsurer. In addition, in a number of jurisdictions, particularly the European Union and the United Kingdom and a small number of U.S. states, a reinsurer is permitted to transfer a reinsurance arrangement to another reinsurer, which may be less creditworthy, without a counterparty’s consent, provided that the transfer has been approved by the applicable regulatory and/or court authority.

For additional information regarding reinsurance, see note 6 of the notes to the consolidated financial statements and “Item 1A—Risk Factors—We may not be able to collect all amounts due to us from reinsurers, reinsurance coverage may not be available to us in the future at commercially reasonable rates or at all and we are exposed to credit risk related to our structured settlements.” For a description of reinsurance-related litigation, see note 17 of the notes to the consolidated financial statements.

Catastrophe Reinsurance
Catastrophes include hurricanes, tornadoes and other windstorms, earthquakes, hail, wildfires, severe winter weather, floods, tsunamis, volcanic eruptions, solar flares and other naturally-occurring events. Catastrophes can also result from terrorist attacks and other intentionally destructive acts including those involving cyber events, nuclear, biological, chemical and radiological events, civil unrest, explosions and destruction of infrastructure. The incidence and severity of catastrophes are inherently unpredictable. The extent of losses from a catastrophe is a function of both the total amount of insured exposure affected by the event and the severity of the event. Most catastrophes are restricted to small geographic areas; however, hurricanes, earthquakes, wildfires, cyber attacks and other events may produce significant damage or loss in larger areas, especially those areas that are heavily populated. For additional information regarding catastrophes, see “Item 1A—Risk Factors—High levels of catastrophe losses, including as a result of factors such as increased concentrations of insured exposures in catastrophe-prone areas and changing climate conditions, could materially and adversely affect our results of operations, our financial position and/or liquidity, and could adversely impact our ratings, our ability to raise capital and the availability and cost of reinsurance." The Company generally seeks to manage its exposure to catastrophes through individual risk selection and the purchase of catastrophe reinsurance. In addition to the Company’s catastrophe reinsurance coverages, the Company is also party to other reinsurance treaties that can provide additional coverage for losses arising from catastrophes, as described in the “Net Retention Policy Per Risk” sections of the respective segment discussions above. The Company conducts reviews of its risk and catastrophe coverages on a regular basis and makes changes as it deems appropriate. On January 1, 2023, the Company did not renew the 2022 Underlying Property Aggregate Catastrophe Excess-of-Loss Reinsurance Treaty, the terms of which were disclosed in the “Reinsurance - Catastrophe Reinsurance” section in Part I, Item 1 of the Company's Annual Report on Form 10-K for the year ended December 31, 2021. The following discussion summarizes the Company’s catastrophe reinsurance coverage at January 1, 2023.
17


Corporate Catastrophe Excess-of-Loss Reinsurance Treaty. This treaty covers the accumulation of certain property losses arising from one or multiple occurrences for the period January 1, 2023 through and including December 31, 2023. The treaty provides for recovery of 100% of the dollar amount of each qualifying loss in excess of a $3.5 billion retention, up to a maximum amount of qualifying losses of $5.5 billion. Therefore, the maximum recovery under the treaty would be $2.0 billion. Qualifying losses for each occurrence are after a $100 million deductible.  The treaty covers all of the Company’s exposures in North America and all waters contiguous thereto. The treaty only provides coverage for terrorism events in limited circumstances and excludes entirely losses arising from nuclear, biological, chemical or radiological attacks. The treaty only provides coverage for cyber events in limited circumstances and excludes losses arising from communicable disease. The Company's underlying insurance coverages generally exclude coverage for communicable disease.

Catastrophe Bonds. The Company has catastrophe protection through an indemnity reinsurance agreement with Long Point Re IV Ltd. (Long Point Re IV), an independent Bermuda company registered as a special purpose insurer under the Bermuda Insurance Act of 1978 and related regulations. The reinsurance agreement meets the requirements to be accounted for as reinsurance in accordance with the guidance for reinsurance contracts. In connection with the reinsurance agreement, Long Point Re IV issued notes (generally referred to as “catastrophe bonds”) to investors in amounts equal to the full coverage provided under the reinsurance agreement as described below. The proceeds of the issuance were deposited in a reinsurance trust account. The businesses covered by this reinsurance agreement are subsets of the Company’s overall insurance portfolio, comprising specified property coverages spread across the following geographic locations: Connecticut, Delaware, District of Columbia, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, Virginia and Vermont.

The reinsurance agreement was entered into in May 2022 and provides coverage of up to $575 million to the Company through May 24, 2026 for certain losses from tropical cyclones, earthquakes, severe thunderstorms or winter storms in the locations listed above. The attachment point and maximum limit under this agreement are reset annually to adjust the expected loss of the layer within a predetermined range. For events up to and including May 24, 2023, this treaty provides up to $575 million part of $700 million coverage, subject to a $2.20 billion retention (i.e., for every dollar of loss between $2.20 billion and $2.90 billion, this treaty provides 82 cents of coverage). The coverage under the reinsurance agreement is limited to specified property coverage written in Personal Insurance; Select Accounts, Middle Market (excluding Excess Casualty and Boiler & Machinery) and National Property and Other in Business Insurance; and Other in Bond & Specialty Insurance. 

Under the terms of the reinsurance agreement, the Company is obligated to pay annual reinsurance premiums to Long Point Re IV for the reinsurance coverage. Amounts payable to the Company under the reinsurance agreement with respect to any covered event cannot exceed the Company's actual losses from such event. The principal amount of the catastrophe bonds will be reduced by any amounts paid to the Company under the reinsurance agreement.

As with any reinsurance agreement, there is credit risk associated with collecting amounts due from reinsurers. With regard to Long Point Re IV, the credit risk is mitigated by a reinsurance trust account that has been funded by Long Point Re IV with money market funds that invest solely in direct government obligations and obligations backed by the U.S. government with maturities of no more than 13 months. The money market funds must have a principal stability rating of at least AAAm by Standard & Poor’s or AAAmmf by Fitch Ratings on the issuance date of the bonds and thereafter must be rated by Standard & Poor’s or Fitch Ratings, as applicable. Other permissible investments include money market funds which invest in repurchase and reverse repurchase agreements collateralized by direct government obligations and obligations of any agency backed by the U.S. government with terms of no more than 397 calendar days, and cash.

At the time the agreement was entered into with Long Point Re IV, the Company evaluated the applicability of the accounting guidance that addresses variable interest entities or VIEs. Under this guidance, an entity that is formed for business purposes is considered a VIE if: (a) the equity investors lack the direct or indirect ability through voting rights or similar rights to make decisions about an entity's activities that have a significant effect on the entity’s operations or (b) the equity investors do not provide sufficient financial resources for the entity to support its activities. Additionally, a company that absorbs a majority of the expected losses from a VIE’s activities or is entitled to receive a majority of the entity’s expected residual returns, or both, is considered to be the primary beneficiary of the VIE and is required to consolidate the VIE in the company’s financial statements.

As a result of the evaluation of the reinsurance agreement with Long Point Re IV, the Company concluded that it was a VIE because the conditions described in items (a) and (b) above were present. However, while Long Point Re IV was determined to be a VIE, the Company concluded that it did not have a variable interest in the entity, as the variability in its results, caused by the reinsurance agreement, is expected to be absorbed entirely by the investors in the catastrophe bonds issued by Long Point Re IV and residual amounts earned by it, if any, are expected to be absorbed by the equity investors (the Company has neither an equity nor a residual interest in Long Point Re IV).
18



Accordingly, the Company is not the primary beneficiary of Long Point Re IV and does not consolidate that entity in the Company’s consolidated financial statements. Additionally, because the Company has no intention to pursue any transaction that would result in it acquiring interest in and becoming the primary beneficiary of Long Point Re IV, the consolidation of that entity in the Company’s consolidated financial statements in future periods is unlikely.

The Company has not incurred any losses that have resulted or are expected to result in a recovery under the Long Point Re IV agreement since its inception.

Northeast Property Catastrophe Excess-of-Loss Reinsurance Treaty. This treaty provides up to $750 million part of $850 million of coverage, subject to a $2.25 billion retention (i.e., for every dollar of loss between $2.25 billion and $3.10 billion, this treaty provides 88 cents of coverage), for losses arising from a single occurrence and allows for one reinstatement. Coverage is provided on an all perils basis, including but not limited to hurricanes, tornadoes, hail storms, earthquakes, winter storms and/or freeze losses (coverage is included for terrorism events in limited circumstances). Coverage for cyber events applies only in limited circumstances, and coverage for communicable disease and nuclear, biological and radiological terrorism attacks is excluded from this treaty. The treaty covers territory from Virginia to Maine for the period from July 1, 2022 through and including June 30, 2023. Losses from a covered event anywhere in North America and waters contiguous thereto may be used to satisfy the retention. Recoveries under the catastrophe bonds (if any) would be first applied to reduce losses subject to this treaty.

Middle Market Earthquake Catastrophe Excess-of-Loss Reinsurance Treaty. This treaty provides for up to $248 million part of $275 million of coverage, subject to a $110 million retention (i.e., for every dollar of loss between $110 million and $385 million, this treaty provides 90 cents of coverage), for losses arising from an earthquake, including other ensuing causes of loss such as fire following and sprinkler leakage, incurred under policies written by Technology, Public Sector Services and Commercial Accounts in Business Insurance for the period from July 1, 2022 through and including June 30, 2023. The treaty covers the United States and Canada, their territories, possessions and waters contiguous thereto.

Personal Insurance Earthquake Catastrophe Excess-of-Loss Reinsurance Treaty. This treaty provides for up to $160 million part of $200 million of coverage, subject to a $170 million retention, for losses occurring from an earthquake, including fire following and sprinkler leakage, incurred by Personal Insurance from January 1, 2023 through and including December 31, 2023. The treaty covers the United States, its territories, possessions and waters contiguous thereto.

Canadian Property Catastrophe Excess-of-Loss Reinsurance Treaty.  This treaty provides coverage for 50% of losses in excess of C$100 million (US$74 million at December 31, 2022) up to C$200 million (US$148 million at December 31, 2022) and for 100% of losses in excess of C$200 million (US$148 million at December 31, 2022) up to C$500 million (US$369 million at December 31, 2022), in each case with respect to the accumulation of net property losses arising out of one occurrence on business written by the Company’s Canadian businesses for the period from July 1, 2022 through and including June 30, 2023. The treaty covers all property written by the Company’s Canadian businesses, including, but not limited to, habitational property, commercial property, inland marine, ocean marine and auto physical damages exposures. Coverage for cyber events applies only in limited circumstances, and coverage for communicable disease and nuclear, biological and radiological terrorism attacks is excluded from this treaty.

Other International Reinsurance Treaties. For other business underwritten in Canada, as well as for business written in the United Kingdom and the Republic of Ireland and in the Company’s operations at Lloyd’s, separate reinsurance protections are purchased locally that have lower net retentions more commensurate with the size of the respective local balance sheet.

Terrorism Risk Insurance Program. The Terrorism Risk Insurance Program is a Federal program administered by the Department of the Treasury authorized through December 31, 2027 that provides for a system of shared public and private compensation for certain insured losses resulting from certified acts of terrorism. For a further description of the program, including the Company’s estimated deductible under the program in 2023, see note 6 of the notes to the consolidated financial statements and “Item 1A—Risk Factors—High levels of catastrophe losses, including as a result of factors such as increased concentrations of insured exposures in catastrophe-prone areas and changing climate conditions, could materially and adversely affect our results of operations, our financial position and/or liquidity, and could adversely impact our ratings, our ability to raise capital and the availability and cost of reinsurance.”

CLAIMS AND CLAIM ADJUSTMENT EXPENSE RESERVES
Claims and claim adjustment expense reserves represent management’s estimate of the ultimate liability for unpaid losses and loss adjustment expenses for claims that have been reported and claims that have been incurred but not yet reported as of the balance sheet date.
 
The Company refines its reserve estimates as part of its regular ongoing process that includes reviews of key assumptions, underlying variables and historical loss experience. The Company reflects adjustments to reserves in the results of operations in the periods in which the estimates are changed. In establishing reserves, the Company takes into account estimated recoveries for reinsurance, salvage and subrogation. The reserves are reviewed regularly by qualified actuaries employed by the Company. For additional information on the process of estimating reserves and a discussion of underlying variables and risk factors, see “Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Estimates.”

The process of estimating loss reserves involves a high degree of judgment and is subject to a number of variables. These variables (discussed by product line in the “Critical Accounting Estimates” section of “Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations”) are affected by both internal and external events, such as changes in claims handling procedures, inflation, judicial trends, the tort environment and the legislative landscape, among others. The impact of many of these items on ultimate costs for claims and claim adjustment expenses is difficult to estimate. Reserve estimation difficulties also differ significantly by product line due to differences in the underlying insurance contract (e.g., claims-made versus occurrence), claim complexity, the volume of claims, the potential severity of individual claims, the determination of the occurrence date for a claim, and reporting lags (the time between the occurrence of the insured event and when it is actually reported to the insurer). Informed judgment is applied throughout the process.

The Company derives estimates for unreported claims and development with respect to reported claims principally from actuarial analyses of historical patterns of loss development by accident year for each business unit, product line and type of exposure. Similarly, the Company derives estimates of unpaid loss adjustment expenses principally from actuarial analyses of historical development patterns and the relationship of loss adjustment expenses to losses for each product line and type of exposure. For a description of the Company’s reserving methods for asbestos and environmental claims, see “Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations—Asbestos Claims and Litigation,” and “—Environmental Claims and Litigation.”

Certain of the Company’s claims and claim adjustment expense reserves are discounted to present value.  See note 8 of the notes to the consolidated financial statements for further discussion.
Reserves on Statutory Accounting Basis
At December 31, 2022, 2021 and 2020, claims and claim adjustment expense reserves (net of reinsurance) prepared in accordance with U.S. generally accepted accounting principles (GAAP reserves) were $91 million higher, $99 million higher and $110 million higher, respectively, than those reported in the Company’s respective annual financial reports filed with insurance regulators, which are prepared in accordance with statutory accounting practices (statutory reserves).
The differences between the amount of reserves reported for GAAP and statutory reporting are primarily due to the differences in accounting for: (i) fee reimbursements associated with large deductible business, (ii) the impact of updated accounting guidance for credit losses adopted January 1, 2020 applicable to structured settlements and (iii) the accounting for reinsurance.

For large deductible business, the Company pays the deductible portion of a casualty insurance claim and then seeks reimbursement from the insured, plus a fee. The associated reserves for claim adjustment expenses are reported gross of the expected fee income (i.e., the reserves are not net of the expected fees) for GAAP reporting. For statutory reporting, the associated reserves are reported net of the expected fee income.

For GAAP reporting, amounts payable under structured settlements for which the Company did not receive a release of its obligation from the claimant are reported in loss reserves and reinsurance recoverables, net of an allowance for estimated uncollectible amounts. The allowance was impacted by the updated accounting guidance for credit losses adopted January 1, 2020 that requires the allowance to be based on expected credit losses. For statutory reporting, structured settlements for which the Company has not obtained a release are disclosed as a contingent liability and not recorded as part of loss reserves.

Reserves for claims and claim adjustment expenses are reported gross of reinsurance recoverables (i.e., without reduction for amounts recoverable for reinsurance) for GAAP reporting. For statutory reporting, the reserves are reported net of reinsurance
20


recoverables. Additionally, reinsurance balances resulting from reinsurance placed to cover losses on insured events occurring prior to the inception of a reinsurance contract (retroactive reinsurance) are included in reinsurance recoverables for GAAP reporting. Statutory accounting practices require retroactive reinsurance balances to be recorded in other liabilities as contra-liabilities rather than in loss reserves.

Asbestos and Environmental Claims
Asbestos and environmental claims are segregated from other claims and are handled separately within the Company’s Strategic Resolution Group, a separate unit staffed by dedicated legal, claim, finance and engineering professionals which also has responsibility for enterprise-wide major case activity. For additional information on asbestos and environmental claims, see “Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations—Asbestos Claims and Litigation” and “—Environmental Claims and Litigation.”

INTERCOMPANY REINSURANCE POOLING ARRANGEMENTS
Most of the Company’s domestic insurance subsidiaries are members of an intercompany property and casualty reinsurance pooling arrangement. Pooling arrangements permit the participating companies to rely on the capacity of the entire pool’s statutory capital and surplus rather than just on its own statutory capital and surplus. Under such arrangements, the members share substantially all insurance business that is written and allocate the combined premiums, losses and expenses.

RATINGS
Ratings are an important factor in assessing the Company’s competitive position in the insurance industry. The Company receives ratings from the following major rating agencies: A.M. Best Company (A.M. Best), Fitch Ratings (Fitch), Moody’s Investors Service (Moody’s) and S&P Global Ratings (S&P). Rating agencies typically issue two types of ratings for insurance companies: claims-paying (or financial strength) ratings, which reflect the rating agency’s assessment of an insurer’s ability to meet its financial obligations to policyholders, and debt ratings, which reflect the rating agency’s assessment of a company’s prospects for repaying its debts and are considered by lenders in connection with the setting of interest rates and terms for a company’s short- and long-term borrowings. Agency ratings are not a recommendation to buy, sell or hold any security, and they may be revised or withdrawn at any time by the rating agency. Each agency’s rating should be evaluated independently of any other agency’s rating. The system and the number of rating categories can vary widely from rating agency to rating agency. Customers usually focus on claims-paying ratings, while creditors focus on debt ratings. Investors use both to evaluate a company’s overall financial strength. The ratings issued on the Company or its subsidiaries by any of these agencies are announced publicly and are available on the Company’s website and from the agencies.

A downgrade in one or more of the Company’s claims-paying ratings could negatively impact the Company’s business volumes and competitive position because demand for certain of its products may be reduced, particularly because some customers require that the Company maintain minimum ratings to enter into, maintain or renew business with it. 

Additionally, a downgrade in one or more of the Company’s debt ratings could adversely impact the Company’s ability to access the capital markets and other sources of funds, including in the syndicated bank loan market, and/or result in higher financing costs.  For example, downgrades in the Company’s debt ratings could result in higher interest expense under the Company’s revolving credit agreement (under which the cost of borrowing could range from the Secured Overnight Financing Rate (SOFR) plus 85 basis points (including a credit spread adjustment) to SOFR plus 147.5 basis points (including a credit spread adjustment), depending on the Company’s debt ratings), the Company’s commercial paper program, or in the event that the Company were to access the capital markets by issuing debt or similar types of securities.  See note 9 of the notes to the consolidated financial statements for a discussion of the Company’s revolving credit agreement and commercial paper program. The Company considers the level of increased cash funding requirements in the event of a ratings downgrade as part of the evaluation of the Company’s liquidity requirements.  The Company currently believes that a one- to two-notch downgrade in its debt ratings would not result in a material increase in interest expense under its existing credit agreement and commercial paper programs. In addition, the Company considers the impact of a ratings downgrade as part of the evaluation of its common share repurchases.

S&P has announced that it intends to change its capital adequacy model. While the proposed model has not been finalized, it could increase the level of capital S&P requires for a particular financial strength rating. As part of its capital management strategy, the Company will continue to make its own assessment of the appropriate level of capital to support the Company’s business operations. For a discussion of the risks to the Company's claims-paying and financial strength ratings, see the risk factor entitled “A downgrade in our claims-paying and financial strength ratings could adversely impact our business volumes,
21


adversely impact our ability to access the capital markets and increase our borrowing costs” included in “Part I—Item 1A—Risk Factors."

INVESTMENT OPERATIONS
The majority of funds available for investment are deployed in a widely diversified portfolio of high quality, liquid, taxable U.S. government, tax-exempt and taxable U.S. municipal and taxable corporate and U.S. agency mortgage-backed bonds. The Company regularly monitors the effective duration of its fixed maturity investments, and the Company’s investment purchases and sales are executed with the objective of having adequate funds available to satisfy its insurance and debt obligations. Generally, the expected principal and interest payments produced by the Company’s fixed maturity portfolio adequately fund the estimated runoff of the Company’s insurance reserves. The Company manages the investment duration relative to its liability duration. In 2022, the estimated effective duration of the Company's portfolio of fixed maturity and short-term security investments increased and the estimated effective duration of the Company’s net insurance liabilities decreased, both changes primarily reflecting the impact of higher interest rates. As a result, at December 31, 2022, the estimated effective duration of the Company's portfolio of fixed maturity and short-term security investments was greater than the estimated effective duration of the Company’s net insurance liabilities. The substantial amount by which the fair value of the fixed maturity portfolio exceeds the value of the net insurance liabilities, as well as the positive cash flow from newly sold policies and the large amount of high-quality liquid bonds, contributes to the Company’s ability to fund claim payments without having to sell illiquid assets or access its credit facilities.

The Company also invests much smaller amounts in equity securities, real estate, private equity limited partnerships, hedge funds, and real estate partnerships and joint ventures. These investment classes have the potential for higher returns but also involve varying degrees of risk, including less stable rates of return and less liquidity.

See note 3 of the notes to the consolidated financial statements for additional information regarding the Company’s investment portfolio.

REGULATION

U.S. State and Federal Regulation

The Company's domestic insurance subsidiaries are collectively licensed to transact insurance business in all U.S. states, the District of Columbia, Guam, Puerto Rico, the U.S. Virgin Islands and the Northern Mariana Islands and are subject to regulation in the various states and jurisdictions in which the subsidiaries transact business. The extent of regulation varies, but generally derives from statutes that delegate regulatory, supervisory, and administrative authority to a department of insurance or finance in each state and jurisdiction. The regulation, supervision, and administration relate, among other things, to standards of solvency that must be met and maintained, the nature of and limitations on investments, premium rates, restrictions on the type and size of risks that may be insured under a single policy, reserves and provisions for unearned premiums, losses and other obligations, deposits of securities for the benefit of policyholders, the licensing of insurers and their agents, approval of policy forms and the regulation of market conduct, including the use of credit and other information in underwriting as well as other underwriting and claims practices. State insurance departments also conduct periodic examinations of the financial condition and market conduct of insurance companies and require the filing of financial and other reports on a quarterly and annual basis.

State insurance regulation continues to evolve in response to the changing economic and business environment as well as efforts by regulators internationally to develop a consistent approach to regulation. While the U.S. federal government has not historically regulated the insurance business, the Federal Insurance Office (or FIO) was established within the U.S. Treasury Department with limited authority as part of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010. FIO has been active in the efforts to develop international regulatory standards for the insurance industry. In response to these international efforts, the state insurance regulators, through the National Association of Insurance Commissioners (NAIC), along with the Federal Reserve and the FIO, are working to consider and develop changes to the U.S. regulatory framework, including the development of regulatory tools to evaluate risks and the availability of capital on a groupwide basis in addition to the current requirements imposed on a legal-entity basis.
These changes are evidenced by the incorporation of supervisory colleges into the U.S. regulatory framework. A supervisory college is a forum of the regulators having jurisdictional authority over a holding company’s various insurance subsidiaries, including foreign insurance subsidiaries, convened to meet with the insurer’s executive management, to evaluate the insurer's business strategies, approach to enterprise risk management and corporate governance from both a groupwide and legal-entity perspective.
23



While insurance in the United States is regulated on a legal-entity basis, the NAIC has adopted changes to its Model Holding Company Act that some states, including the State of Connecticut, have enacted to allow the insurance commissioner to be designated as the groupwide supervisor (i.e., lead regulator) for the insurance holding company system based upon certain criteria, including the jurisdiction of domicile of the insurance subsidiaries holding the majority of the insurance group’s premiums, assets, or liabilities. Based upon these criteria, the State of Connecticut Insurance Department is designated as the Company's lead regulator and coordinates supervisory colleges for the Company. Additionally, the NAIC has recently adopted changes to its Model Holding Company Act to require certain insurance groups to file a Group Capital Calculation to allow the groupwide supervisor (lead state) to evaluate the risks and available capital on a groupwide basis in addition to the risk-based capital requirements currently imposed on a legal-entity basis. The State of Connecticut amended its holding company act to incorporate the recent changes to the NAIC Model Holding Company Act and will require insurers, including the Company, to file a Group Capital Calculation beginning in 2023. These changes could result in an increase in the amount of capital the Company's insurance subsidiaries are required to have and could subject the Company to increased regulation.

Insurance Regulation Concerning Dividends from Insurance Subsidiaries. The Company's principal domestic insurance subsidiaries are domiciled in the State of Connecticut. The Connecticut insurance holding company laws require notice to, and approval by, the state insurance commissioner for the declaration or payment of any dividend from an insurance subsidiary that, together with other distributions made within the preceding twelve months, exceeds the greater of 10% of the insurance subsidiary’s statutory capital and surplus as of the preceding December 31, or the insurance subsidiary’s net income for the twelve-month period ending the preceding December 31, in each case determined in accordance with statutory accounting practices and by state regulation. This declaration or payment is further limited by the amount of adjusted unassigned surplus held by the insurance subsidiaries, as determined in accordance with statutory accounting practices.

The insurance holding company laws of states in which the Company's other domestic insurance subsidiaries are domiciled generally contain similar, although in some instances somewhat more restrictive, limitations on the payment of dividends. These insurance subsidiaries, as well as the insurance subsidiaries domiciled in Connecticut, may also be subject to similar dividends limitations imposed by states in which those subsidiaries are considered commercially domiciled as a result of the amount of business written in those states.

Rate and Rule Approvals. TRV’s domestic insurance subsidiaries are subject to each state’s laws and regulations regarding rate and rule approvals. The applicable laws and regulations generally establish standards to ensure that rates are not excessive, inadequate, unfairly discriminatory or used to engage in unfair price competition. An insurer’s ability to adjust rates and the relative timing of the process are dependent upon each state’s requirements. Many states have enacted variations of competitive ratemaking laws, which allow insurers to set certain premium rates for certain classes of insurance without having to obtain the prior approval of the state insurance department.

Requirements for Exiting Geographic Markets and/or Canceling or Nonrenewing Policies. Many states have laws and regulations which may impact the timing and/or the ability of an insurer to either discontinue or substantially reduce its writings in that state. These laws and regulations typically require prior notice and in some instances insurance department approval prior to discontinuing a line of business or withdrawing from that state. In addition, all states impose limitations on cancellations or non-renewals of certain policies, including in particular, limitations on the reasons for cancellations and on the timing of non-renewals.

Regulatory and Legislative Responses to Catastrophes. States have from time to time passed legislation, and regulators have taken action, that have the effect of limiting the ability of insurers to manage catastrophe risk, such as legislation restricting insurers from reducing exposures or withdrawing from catastrophe-prone areas or mandating that insurers participate in residual markets involving catastrophe-prone areas. Participation in residual market mechanisms has resulted in, and may in the future result in, significant losses or assessments to insurers, including the Company, and, in certain states, those losses or assessments may not be commensurate with the Company's direct catastrophe exposure in those states. If the Company's competitors leave states that have residual market mechanisms, the remaining insurers, including the Company, may be subject to significant increases in losses or assessments following a catastrophe. In addition, following catastrophes, there have been, and may in the future be, legislative and administrative initiatives and court decisions that seek to expand insurance coverage for catastrophe claims beyond the original intent of the policies, seek to prevent the application of deductibles included in the policies or seek to limit the exercise of certain rights available to insurers under the policies. Also, the Company's ability to adjust policy language or terms, including deductible levels, or to increase pricing to the extent necessary to offset rising claim costs related to catastrophes requires approval of insurance regulatory authorities in certain states. The Company's ability or its willingness to manage its catastrophe exposure by raising prices, modifying policy terms or reducing exposure to certain geographies may be limited due to considerations of public policy, an evolving political environment and/or changes in general economic
24


conditions. Furthermore, reduction or elimination of the National Flood Insurance Program could result in an increase in the Company's exposure to flood risk if insurers become required to cover flood risk under certain types of policies.
Assessments for Guaranty Funds and Second-Injury Funds and Other Mandatory Assigned Risk and Reinsurance Arrangements. As a condition of their authority to transact insurance in virtually all states, property and casualty insurers, including the Company’s domestic insurance subsidiaries, are required to be a member of each state’s guaranty association and to bear a portion of the losses covered by the guaranty association (subject to a statutory maximum covered loss amount which varies by state) suffered by claimants of insurers that become insolvent. Additionally, many states also have laws that establish second-injury funds to provide compensation to injured employees for the aggravation of a prior injury or disability.

The Company's domestic insurance subsidiaries are also required to participate in various involuntary assigned risk pools, principally involving workers’ compensation, automobile insurance, property damage due to wind (windpools) in states prone to property damage from hurricanes and Fair Access to Insurance Requirements (FAIR) plans, as well as automobile assigned risk plans the results of which are not pooled with other carriers, which provide various insurance coverages to individuals or other entities that otherwise are unable to purchase that coverage in the voluntary market.

Other assessments include charges mandated by statute or regulatory authority that are related directly or indirectly to underwriting activities. Examples of such mechanisms include, but are not limited to, the Florida Hurricane Catastrophe Fund, Florida Citizens Property Insurance Corporation, National Workers’ Compensation Reinsurance Pool, various workers’ compensation related funds (e.g., the Florida Special Disability Trust), North Carolina Beach Plan, Louisiana Citizens Property Insurance Corporation, and the Texas Windstorm Insurance Association. Amounts payable or paid as a result of arrangements that are in substance reinsurance, including certain involuntary pools where insurers are required to assume premiums and losses from those pools, are accounted for as reinsurance (e.g., National Workers’ Compensation Reinsurance Pool, North Carolina Beach Plan). Amounts related to assessments from arrangements that are not reinsurance are reported as part of “General and Administrative Expenses,” such as the Florida Special Disability Trust. For additional information concerning assessments for guaranty funds and second-injury funds and other mandatory assigned risk and reinsurance agreements including state-funding mechanisms, see “Item 1A—Risk Factors.”

Insurance Regulatory Information System (IRIS). The NAIC developed the IRIS to help state regulators identify companies that may require regulatory attention. Financial examiners review annual financial statements and the results of key financial ratios based on year-end data with the goal of identifying insurers that appear to require immediate regulatory attention. Each ratio has an established “usual range” of results. A ratio result falling outside the usual range, however, is not necessarily considered adverse; rather, unusual values are used as part of the regulatory early monitoring system. Furthermore, in some years, it may not be unusual for financially sound companies to have several ratios with results outside the usual ranges. Generally, an insurance company may become subject to regulatory scrutiny or, depending on the company’s financial condition, regulatory action if certain of its key IRIS ratios fall outside the usual ranges and the insurer’s financial condition is trending downward.

Based on preliminary 2022 IRIS ratios calculated by the Company for its lead domestic insurance subsidiaries, The Travelers Indemnity Company had results outside the normal range for one IRIS ratio due to the size of its investments in certain non-fixed maturity securities, while Travelers Casualty and Surety Company had results outside the normal range for one IRIS ratio due to the amount of dividends received from its subsidiaries. In 2021, The Travelers Indemnity Company and Travelers Casualty and Surety Company had results outside the normal range for these same ratios.
Management does not anticipate regulatory action as a result of the 2022 IRIS ratio results for the lead insurance subsidiaries or their insurance subsidiaries. In all instances in prior years, regulators have been satisfied upon follow-up that no regulatory action was required.

Risk-Based Capital (RBC) Requirements. The NAIC has an RBC requirement which sets forth minimum capital standards for most U.S.-based property and casualty insurance companies that is intended to raise the level of protection for policyholder obligations. The Company’s U.S. insurance subsidiaries are subject to these NAIC RBC requirements based on laws that have been adopted by individual states. These requirements subject insurers having policyholders’ surplus less than that required by the RBC calculation to varying degrees of regulatory action, depending on the level of capital inadequacy. Each of the Company’s U.S. insurance subsidiaries had policyholders’ surplus at December 31, 2022 and 2021 significantly above the level at which any RBC regulatory action would occur.

While there is currently no group regulatory capital requirement in place for insurers in the United States, a comparison of an insurer’s policyholders’ surplus on a combined basis to the legal entity NAIC RBC requirements on a combined basis can provide useful information regarding an insurance group’s overall capital adequacy in the U.S. The amount of policyholders’ surplus held by the Company’s U.S. insurance subsidiaries at December 31, 2022, determined on a combined basis,
25


significantly exceeded the level at which the subsidiaries would be subject to RBC regulatory action (company action level) on a combined basis at that date.

The RBC formulas have not been designed to differentiate among adequately capitalized companies that operate with levels of capital above the RBC requirement. Therefore, it is inappropriate and ineffective to use the formulas to rate or to rank these companies.
Investment Regulation. Insurance company investments must comply with applicable laws and regulations which prescribe the kind, quality and concentration of investments. In general, these laws and regulations permit investments in federal, state and municipal obligations, corporate bonds, preferred and common equity securities, mortgage loans, real estate and certain other investments, subject to specified limits and certain other qualifications, depending on the type of investment. At December 31, 2022 and 2021, the Company was in compliance with these laws and regulations.

Federal Regulation. As mentioned above, the Dodd-Frank Act established a Federal Insurance Office (FIO) within the U.S. Department of the Treasury. The FIO has limited regulatory authority and is empowered to gather data and information regarding the insurance industry and insurers, but it has in the past recommended an expanded federal role in some circumstances. The Dodd-Frank Act also gives the Federal Reserve supervisory authority over a number of non-bank financial services holding companies, including holding companies with insurance company subsidiaries, if they are designated by a two-thirds vote of a Financial Stability Oversight Council (the FSOC) as “systemically important financial institutions” (SIFI) or own a bank or thrift. The Company, based upon the FSOC’s rules and interpretive guidance, has not been designated as a SIFI and is not subject to regulation by the Federal Reserve. Nonetheless, it is possible that FSOC may change its rules or interpretations in the future and conclude that the Company is a SIFI. If the Company were designated as a SIFI, the Federal Reserve’s supervisory authority could include the ability to impose heightened financial regulation and could impact requirements regarding the Company's capital, liquidity and leverage as well as its business and investment conduct. The Dodd-Frank Act also authorizes assessments to pay for the resolution of SIFIs that have become insolvent. The Company (as a financial company with more than $50 billion in assets) could be assessed, and although any such assessment is required to be risk weighted (i.e., riskier firms pay more), such costs could be material and are not currently estimable. As a result of the foregoing, the Dodd-Frank Act, including any changes thereto, or other additional federal regulation that is adopted in the future, could impose additional burdens on the Company, including impacting the ways in which the Company conducts its business, increasing compliance costs and duplicating state regulation, and could result in a competitive disadvantage, particularly relative to other competitors that may not be subject to the same level of regulation.

International Regulation

The Company's insurance subsidiaries based in Canada, and the Canadian branch of one of the Company’s U.S. insurance subsidiaries, are regulated for solvency purposes by the Office of the Superintendent of Financial Institutions (OSFI) under the provisions of the Insurance Companies Act (Canada). These Canadian subsidiaries and the Canadian branch are also subject to Canadian provincial and territorial insurance legislation and regulation, governing market conduct, including pricing, underwriting, coverage and claim conduct, in varying degrees by province/territory and by product line.

The Company's insurance subsidiaries based in the United Kingdom (U.K.) are regulated by two regulatory bodies, The Prudential Regulation Authority (PRA) and The Financial Conduct Authority (FCA). The PRA’s primary objective is to promote the safety and soundness of insurers for the protection of policyholders, while the FCA has three operational objectives: (i) to secure an appropriate degree of protection for consumers, (ii) to protect and enhance the integrity of the U.K. financial system, and (iii) to promote effective competition in the interests of consumers. One of the Company's U.K. insurance subsidiaries is also authorized in the U.S. as a surplus lines insurer subject to U.S. state regulation applicable to such insurers.

The Company's managing agency (Travelers Syndicate Management Limited) (TSML) of its Lloyd’s syndicate (Syndicate 5000 at Lloyd's) is also regulated by the PRA and the FCA, which have delegated certain regulatory responsibilities to the Council of Lloyd's. Travelers Syndicate 5000 is able to write business in over 200 countries and territories throughout the world by virtue of Lloyd's international licenses. In each such jurisdiction, the policies written by TSML, as part of Lloyd’s, are subject to the laws and insurance regulations of that jurisdiction. Travelers Underwriting Agency Limited, which as an insurance intermediary is regulated by the FCA, produces insurance business for Travelers Syndicate 5000. Xbridge Limited, operating under the trade name Simply Business, is an insurance broker that provides products for small commercial customers in the U.K. via a panel of insurance companies and is also regulated by the FCA.
Travelers is conducting its insurance operations in the Republic of Ireland and across the EU through an insurance subsidiary that is incorporated in the Republic of Ireland and authorized and regulated by the Central Bank of Ireland. Certain operations are conducted in the U.K. through a U.K. branch of the Irish subsidiary, which is supervised by the PRA and FCA as well as the
26


Central Bank of Ireland. Since January 1, 2019, the Company has used a Lloyd's insurance subsidiary in Brussels, Belgium (Lloyd's Brussels) to cover its Lloyd's customers' risks in the EU. Lloyd’s Brussels is regulated by the National Bank of Belgium.

During 2022, the Company's operations in the Republic of Ireland were also subject to regulation by the European Union (EU). Generally, EU requirements are adopted by the EU and then implemented by enabling legislation in the member countries. Significant areas of oversight and influence from the EU include capital and solvency requirements (Solvency II), competition law and antitrust regulation, intermediary and distribution regulation, gender discrimination and data security and privacy. Under Solvency II, it is possible that the U.S. parent of a European Union subsidiary could be subject to certain Solvency II requirements if the regulator determines that the subsidiary’s capital position is dependent on the parent company and the U.S. Parent is not already subject to regulations deemed “equivalent” to Solvency II. Currently, as a result of the Covered Agreements described below, the state regulatory system governing U.S. insurers is deemed “equivalent” for purposes of Solvency II.

Beginning December 31, 2020, the Company's operations in the U.K. were no longer subject to EU regulations. The applicability of the EU requirements to the Company's businesses in the U.K. may change in ways yet to be determined as a result of the U.K.’s exit from the EU. It is expected that the U.K. will continue to apply the requirements of Solvency II to insurers operating in the U.K.

Each of the Company’s foreign insurance subsidiaries had capital significantly above their respective regulatory requirements at December 31, 2022.

Regulators in countries where the Company has operations are working with the International Association of Insurance Supervisors (IAIS) (and with the NAIC, the Federal Reserve and FIO in the U.S.) to consider changes to insurance company supervision, including group supervision and group capital requirements.

The IAIS has developed a methodology for identifying “global systemically important insurers” (G-SIIs) and high-level policy measures that will apply to the G-SIIs. The methodology and measures were endorsed by the Financial Stability Board (FSB) which was created by the Group of Twenty (or G-20); however, identification of G-SIIs was suspended at the beginning of 2020. In December 2022, the FSB, in consultation with the IAIS, decided to discontinue the annual identification of G-SIIs. Going forward the FSB will utilize a newly developed framework to inform its considerations of systemic risk in the insurance sector. The Company has not previously been designated as a G-SII by the FSB; however, it is possible that the designation of G-SIIs could be reinstituted, the methodologies or framework could be amended or interpreted differently in the future and the Company could be named as a G-SII.

The IAIS completed its Common Framework for the Supervision of Internationally Active Insurance Groups (known as ComFrame). ComFrame is intended to apply heightened regulatory requirements similar to those being developed for G-SIIs to internationally active insurance groups (or “IAIGs”), including group supervision, group capital requirements, and resolution planning, i.e., a written plan developed by a financial group detailing how it would be wound down in the event of an insolvency. While the Company would not be considered an IAIG under the current criteria in ComFrame, it is possible that the criteria could be changed. If the Company is designated as an IAIG or the NAIC and individual states adopt ComFrame or similar provisions for large insurers, the Company could be subject to increased supervision and higher capital standards.

Covered Agreements

The U.S. Department of the Treasury and the Office of the U.S. Trade Representative have signed covered agreements (the Covered Agreements) regarding prudential (solvency) insurance and reinsurance measures with both the EU and the U.K. The Covered Agreements include three areas of prudential insurance supervision: reinsurance contracts, group supervision, and the exchange of information between U.S. and U.K. regulators and between U.S. and EU regulators on insurers and reinsurers that operate in the U.S., U.K. and EU markets. The Covered Agreement with the EU went into effect in April 2018, while the Covered Agreement with the U.K. took full effect upon the U.K.'s exit from the EU on January 31, 2020. The Covered Agreements are intended to promote cooperation between U.S. insurance regulators and EU and U.K. insurance regulators and to limit the ability of the EU and the U.K. to apply solvency and group capital requirements to the worldwide operations of any U.S. insurer operating in the EU or the U.K. It is possible that individual members of the EU could differ in how they adopt or implement the Covered Agreement, resulting in greater regulation and higher capital standards as well as inconsistent regulatory requirements among the jurisdictions in which the Company does business. While it is not yet known how or if these actions will impact the Company, such regulation could result in increased costs of compliance, increased disclosure and less flexibility in capital management, and could adversely impact the Company's results of operations and limit its growth.

27


The Covered Agreements eliminate the collateral and local presence requirements for EU and U.K. reinsurers operating in the U.S., and for U.S. reinsurers operating in the EU and U.K., as a condition for credit for reinsurance in regulatory reporting and capital requirements. The prospective elimination of the collateral requirements is conditioned on the reinsurer meeting capital and solvency standards and maintaining a record of prompt payments to ceding insurers. While the collateral requirement is removed for reinsurers meeting these standards, insurers and reinsurers are not prohibited from negotiating and putting into place collateral as part of reinsurance agreements. The Covered Agreements include a five-year transition period to full compliance in the impacted jurisdictions.

Insurance Holding Company Statutes

As a holding company, TRV is not regulated as an insurance company. However, since TRV owns capital stock in insurance subsidiaries, it is subject to state insurance holding company statutes, as well as certain other laws, of each of its insurance subsidiaries’ states of domicile. All holding company statutes, as well as other laws, require disclosure and, in some instances, prior approval of certain transactions between an insurance company and an affiliate. The holding company statutes and other laws also require, among other things, prior approval for acquiring control of a domestic insurer and the payment of extraordinary dividends or distributions.

Insurance Regulations Concerning Change of Control. Many state insurance regulatory laws contain provisions that require advance approval by state agencies of any change in control of an insurance company that is domiciled, or, in some cases, having substantial business in a state such that the insurance company is deemed to be commercially domiciled in that state.

The laws of many states also contain provisions requiring pre-notification to state agencies prior to any change in control of a non-domestic insurance company admitted to transact business in that state. While these pre-notification statutes do not authorize the state agency to disapprove the change of control, they do authorize issuance of cease-and-desist orders with respect to the non-domestic insurer if it is determined that some conditions, such as undue market concentration, would result from the acquisition.

Any transactions that would constitute a change in control of any of TRV’s insurance subsidiaries would generally require prior approval by the insurance departments of the states in which the insurance subsidiaries are domiciled or commercially domiciled. Pre-acquisition notification may also be required in those states that have adopted pre-acquisition notification provisions and in which such insurance subsidiaries are admitted to transact business.

One of TRV’s insurance subsidiaries and its operations at Lloyd’s are domiciled in the United Kingdom and one of its insurance subsidiaries is domiciled in the Republic of Ireland. Insurers in the United Kingdom and the Republic of Ireland are subject to change of control restrictions, including approval of the PRA and FCA and of the Central Bank of Ireland, respectively. TRV’s insurance subsidiaries domiciled in, or authorized to conduct insurance business in, Canada are also subject to regulatory change of control restrictions, including approval of OSFI. TRV’s Brazilian joint venture is subject to regulatory change of control and other share transfer restrictions, including approval of the Superintendência de Seguros Privados (SUSEP).

These requirements may deter, delay or prevent transactions affecting the control of or the ownership of common stock, including transactions that could be advantageous to TRV’s shareholders.

Regulatory Developments

The state insurance regulatory framework has been under continuing scrutiny, and some state legislatures have considered or enacted laws that may alter or increase state authority to regulate insurance companies and insurance holding companies. Further, the NAIC and state insurance regulators continually re-examine existing laws and regulations, specifically focusing on modifications to holding company statutes, regulations, interpretations of existing laws and the development of new laws and regulations.

As part of these changes, insurance holding company regulations were amended to require insurers who are part of a holding company system to file an enterprise risk report to provide the lead insurance regulator with a summary of the company’s Enterprise Risk Management (ERM) framework, including the material risks within the insurance holding company system that could pose risk to the insurance entities within the holding company system. Insurers having premium volume above certain thresholds, including the Company, are also required to perform at least annually a self-assessment of their current and future risks, including their likely future solvency position (known as an own risk and solvency assessment or ORSA) and file a confidential report with the insurer’s lead insurance regulator. The requirement for an insurer to conduct an ORSA is intended to foster an effective level of ERM for all insurers within a holding company system, and to provide a group-wide perspective
28


on risks and capital as a supplement to the legal entity view. ORSA is now included in the International Association of Insurance Supervisors (IAIS) standards and is in various stages of implementation in the United States, the U.K., Europe, Canada, and other jurisdictions. It is possible that, as a result of ORSA and the manner in which it may be used by insurance regulators, the Company's states of domicile or other regulatory bodies may require changes in its ERM process (e.g., prescribe the use of specific models or the application of certain assumptions or scenarios in the Company’s models) that have the effect of limiting the Company's ability to write certain risks, limit its risk appetite or reduce its capital management flexibility. See “Item 1—Business—Enterprise Risk Management” for further discussion of the Company’s ERM.

ENTERPRISE RISK MANAGEMENT
The Company's Enterprise Risk Management (ERM) activities involve both the identification and assessment of a broad range of risks and the execution of coordinated strategies to effectively manage these risks. Since certain risks can be correlated with other risks, an event or a series of events can impact multiple areas of the Company simultaneously and have a material effect on the Company’s results of operations, financial position and/or liquidity. This requires an entity-wide view of risk and an understanding of the potential impact on all aspects of the Company’s operations. It also requires the Company to manage its risk-taking to be within its risk appetite in a prudent and balanced effort to create and preserve value for all of the Company’s stakeholders. ERM also includes an evaluation of the Company’s risk capital needs, which takes into account regulatory requirements and credit rating considerations, in addition to economic and other factors. ERM at the Company is an integral part of its business operations. All risk owners across all functions, all corporate leaders and the Board of Directors are engaged in ERM. ERM involves risk-based analytics, as well as reporting and feedback throughout the enterprise in support of the Company’s long-term financial strategies and objectives.

The Company uses various analyses and methods, including proprietary and third-party modeling processes, to make underwriting and reinsurance decisions designed to manage its exposure to catastrophic events. In addition to catastrophe modeling and analysis, the Company also models and analyzes its exposure to other extreme events. The Company also utilizes proprietary and third-party modeling processes to evaluate capital adequacy. These analytical techniques are an integral component of the Company’s ERM process and further support the Company’s long-term financial strategies and objectives.

In addition to the day-to-day ERM activities within the Company’s operations, key internal risk management functions include, among others, the Management and Operating Committees (comprised of the Company’s Chief Executive Officer and the other most senior members of management); the Enterprise, Segment and Function (including Catastrophe, Cyber, etc.) Risk Committees of management; the Executive Crisis Management Team; the Committee on Climate, Energy and the Environment; and the Credit Committee. A senior executive team comprised of the Chief Risk Officer and the Enterprise Chief Underwriting Officer oversees the ERM process.  The mission of this team is to facilitate risk assessment and to collaborate in implementing effective risk management strategies throughout the Company. Another strategic ERM objective of this team includes working across the Company to enhance effective and realistic risk modeling capabilities as part of the Company’s overall effort to understand and manage its portfolio of risks to be within its risk appetite. Board oversight of ERM is provided by the Risk Committee of the Board of Directors, which reviews the strategies, processes and controls pertaining to the Company’s insurance operations and oversees the implementation, execution and performance of the Company’s ERM program. The Risk Committee of the Board of Directors meets with senior management at least four times a year to discuss ERM activities and provides a report to the full Board of Directors after each such meeting.

The Company’s ERM efforts build upon the foundation of an effective internal control environment.  ERM expands the internal control objectives of effective and efficient operations, reliable financial reporting and compliance with applicable laws and regulations, to foster, lead and support an integrated, risk-based culture within the Company that focuses on value creation and preservation.  However, the Company can provide only reasonable, not absolute, assurance that these objectives will be met.  Further, the design of any risk management or control system must reflect the fact that there are resource constraints, and the benefits must be considered relative to their costs.  As a result, the possibility of material financial loss remains in spite of the Company’s significant and comprehensive ERM efforts.  An investor should carefully consider the risks and all of the other information set forth in this annual report, including the discussions included in “Item 1A—Risk Factors,” “Item 7A—Quantitative and Qualitative Disclosures About Market Risk,” and “Item 8—Financial Statements and Supplementary Data.”

The average employee tenure at the Company is 11 years, and over 20 years for the Company’s approximately 700 most senior leaders. The Company’s average global voluntary turnover rate over the past three years was approximately 9%. The Company believes that these employee tenure and voluntary turnover rates are due, in part, to the resources and support the Company provides to employees throughout their careers, as discussed below.

Maintaining an Ethical Culture

The Company’s culture of honesty, integrity and accountability is critical to its long-term success. To support this culture, the Company promotes ethics and compliance awareness across its operations. On an annual basis, all employees of the Company’s wholly owned subsidiaries are required to complete the Company’s ethics training and certify that they have reviewed, understand and agree to comply with the Company’s Code of Business Conduct and Ethics and other applicable Company policies.

The Company provides employees with multiple channels to raise concerns, including the Human Resources, Employee Relations and Compliance functions, as well as the Travelers Ethics Helpline. The Company’s independently administered Ethics Helpline is available to employees and others 24 hours a day, seven days a week to report issues or seek guidance confidentially and anonymously. Trained professionals investigate each concern and, where appropriate, escalate it internally. In addition, the Company maintains a formal Whistleblowing and Non-Retaliation Policy that prohibits retaliation against, or discipline of, an employee who raises concerns in good faith.

Employee Engagement

The Company strives to deliver an employee experience that engages its workforce and strengthens the organization. The Company maintains an Employee Experience function that is responsible for, among other things, an employee experience program that is designed to help drive superior business performance. This function helps the Company create and enhance programs designed to improve employee engagement, reduce attrition and support the retention, growth and satisfaction of the Company’s employees.

The Company uses various methods to evaluate the employee experience and the success of its employee engagement efforts, as well as to inform the strategies the Company uses to enhance those efforts. In addition, the Company’s Chief Human Resources Officer meets regularly with the Chief Executive Officer and other senior leaders to discuss employee engagement strategies and the Company’s progress.

Based on the Company’s employee tenure and voluntary turnover rates, as discussed above, as well as other means the Company uses to evaluate the employee experience and the success of its engagement efforts, the Company believes that its engagement efforts are effective.

Learning and Development

The Company offers various learning and development opportunities to provide its employees with the skills and capabilities they need to be successful. For example, managers participate in the Company’s leadership workshop, Leadership Challenge©, which provides an overview of key leadership practices at the Company. These practices are designed to enable leaders to increase engagement and inclusion, lead change, drive innovation, tie business goals to a greater purpose and coach people to higher levels of performance. The Company also offers three additional foundational workshops centered on leadership: Leadership Principles, Coaching for Performance Excellence, and Leading World Class Teams.

In addition, the Company offers career mentorship and development programs for both entry-level and experienced professionals. For example, the Company’s Development Programs provide employees with an opportunity to progress through a steady career path in a specific discipline such as Actuarial, Business Insights & Analytics, Data Science, Finance, Human Resources, Technology, Operations, Underwriting, Investments or Product Management. Participants complete assignments and rotations designed to help them build upon their strategic thinking skills and business acumen, provide the foundational knowledge and technical skills necessary for success and include on-the-job training, classroom instruction, self-study materials and independent work in an assigned business area. These programs have been a part of the Company’s talent strategy for many years and remained robust through the pandemic.

The Company also maintains a senior-level position responsible for monitoring the development of talented employees to support them in developing the skills necessary to advance their careers and expanding their relationships to ensure their success.

Diversity and Inclusion

The Company believes that its diversity and inclusion efforts are important to its success. The Vice President of Diversity and Inclusion leads the Company’s diversity and inclusion efforts. The Company also has a Diversity Council that is chaired by the Chairman and Chief Executive Officer, comprising the 41 members of the Company’s Operating Committee.

The Company provides training, development and cultural events to encourage an inclusive culture among its employees, including the Company’s leadership. Among others, the Company offers training with respect to conscious inclusion, unconscious bias, and harassment awareness, as ways to ensure a respectful work environment and adherence to applicable legal requirements.
The Company also has eight Diversity Networks – voluntary groups led by employees, dedicated to fostering a diverse and inclusive work environment. The networks help foster the retention, development and success of the Company’s employees through networking, mentorship and community volunteer opportunities. In addition, these groups are a resource for the Company’s business leaders, providing them with important insights and perspectives. More than 12,000 employees – nearly 40% of the Company's employee population – are members of one or more of the Company's Diversity Networks.
The Company also continues to improve its diverse talent pipeline. The Company has established deliberate recruiting, retention and development practices that are tailored to deepen diverse talent pools and broaden advancement opportunities. These practices include matching upcoming leaders with mentors within the organization and offering workshops to advance their careers within the Company. The Company also uses various talent acquisition strategies, including sourcing strategies and initiatives and partnerships with college diversity groups and other organizations, to help create a pipeline of diverse candidates.

The Company has made significant progress over the past decade in increasing its diverse talent. In each of the last 10 years, the Company has increased the percentage of people of color (as defined by the U.S. Equal Employment Opportunity Commission's EEO-1 race and ethnicity categories for the U.S.) in its U.S. workforce. As of December 31, 2022, women and people of color represented approximately 54% and 27% of its U.S. workforce, respectively. The Company continues to make
31


progress in promoting women and people of color. In each of the last 10 years, the Company has increased the percentage of women and people of color in U.S. management-level positions.

Performance and Succession

The Company’s performance management strategy is designed to develop the Company’s talent and equip employees with the skills and resources necessary to ensure the Company’s continued success. To that end, managers assist with setting and monitoring goals, planning, development and discussing opportunities for improvement throughout the year.
The Company also conducts a comprehensive annual talent review, which includes succession planning, to identify and prepare talented employees for future leadership positions. Each line of business identifies talented employees and succession candidates for targeted development and advancement opportunities. This talent review process culminates with the Chief Executive Officer and those reporting directly to him meeting to review succession plans for key positions. In addition, the Chief Executive Officer regularly meets with the Nominating and Governance Committee of the Board of Directors and the full Board of Directors to discuss succession-related matters.
Compensation and Benefits

The Company’s compensation and benefits programs are designed to attract, motivate and retain high performing employees and to help employees be healthy and productive in all aspects of their lives.

Paying employees equitably is the foundation of the Company’s performance-based culture. The Company has comprehensive processes and controls in place and reviews its compensation practices annually with independent, outside experts, in each case to help ensure equitable pay across the Company. Based in part on these measures, the Company believes that it pays its employees equitably, regardless of gender, race or any other protected classification.

The Company’s minimum hourly wage in the United States is $18. As calculated and reported in the Company’s most recent Proxy Statement filed in April 2022, excluding the Company's Chairman and Chief Executive Officer, (i) the median of the annual total compensation of all the Company’s employees was nearly $110,000, and (ii) the median of the annual total compensation of the Company’s full-time U.S. employees who worked for the Company for the entire year, who comprised over 90% of its U.S. workforce, was more than $115,000.

The costs of the risks associated with these pools are charged back to insurance carriers in proportion to their direct writings.
Assumed reinsuranceInsurance risks acquired from a ceding company.
Book value per shareTotal common shareholders’ equity divided by the number of common shares outstanding.
BrokerOne who negotiates contracts of insurance or reinsurance on behalf of an insured party, receiving a commission from the insurer or reinsurer for placement and other services rendered.
CapacityThe percentage of statutory capital and surplus, or the dollar amount of exposure, that an insurer or reinsurer is willing or able to place at risk. Capacity may apply to a single risk, a program, a line of business or an entire book of business. Capacity may be constrained by legal restrictions, corporate restrictions or indirect restrictions.

It excludes certain types of losses that by law or custom are considered as being exclusively within the scope of other types of insurance, such as fire or marine.
34


Catastrophe
A severe loss designated a catastrophe by internationally recognized organizations that track and report on insured losses resulting from catastrophic events, such as Property Claim Services (PCS) for events in the United States and Canada. Catastrophes include hurricanes, tornadoes and other windstorms, earthquakes, hail, wildfires, severe winter weather, floods, tsunamis, volcanic eruptions, solar flares and other naturally-occurring events. Catastrophes can also be man-made, such as terrorist attacks and other intentionally destructive acts, including those involving nuclear, biological, chemical and radiological events, cyber events, civil unrest, explosions and destruction of infrastructure. Each catastrophe has unique characteristics and catastrophes are not predictable as to timing or amount. Their effects are included in net and core income and claims and claim adjustment expense reserves upon occurrence. A catastrophe may result in the payment of reinsurance reinstatement premiums and assessments from various pools. The Company’s threshold for disclosing catastrophes is primarily determined at the reportable segment level. If a threshold for one segment or a combination thereof is exceeded and the other segments have losses from the same event, losses from the event are identified as catastrophe losses in the segment results and for the consolidated results of the Company. Additionally, an aggregate threshold is applied for International business across all reportable segments. For 2022, the threshold ranged from approximately $20 million to $30 million of losses before reinsurance and taxes.
Catastrophe lossLoss and directly identified loss adjustment expenses from catastrophes, as well as related reinsurance reinstatement premiums and assessments from various pools.
Catastrophe reinsuranceA form of excess-of-loss reinsurance which, subject to a specified limit, indemnifies the ceding company for the amount of loss in excess of a specified retention with respect to an accumulation of losses and related reinsurance reinstatement premiums resulting from a catastrophic event. The actual reinsurance document is called a “catastrophe cover.” These reinsurance contracts are typically designed to cover property insurance losses but can be written to cover casualty insurance losses such as from workers’ compensation policies.
Cede; ceding companyWhen an insurer reinsures its liability with another insurer or a “cession,” it “cedes” business and is referred to as the “ceding company.”
Ceded reinsuranceInsurance risks transferred to another company as reinsurance. See “Reinsurance.”
ClaimRequest by an insured for indemnification by an insurance company for loss incurred from an insured peril.
Claim adjustment expensesSee “Loss adjustment expenses (LAE).”
Claims and claim adjustment expenses
See “Loss” and “Loss adjustment expenses (LAE).”
Claims and claim adjustment expense reserves
See “Loss reserves.”
CohortA group of items or individuals that share a particular statistical or demographic characteristic. For example, all claims for a given product in a given market for a given accident year would represent a cohort of claims.
35


Combined ratio
For Statutory Accounting Practices (SAP), the combined ratio is the sum of the SAP loss and LAE ratio and the SAP underwriting expense ratio as defined in the statutory financial statements required by insurance regulators. The combined ratio as used in this report is the equivalent of, and is calculated in the same manner as, the SAP combined ratio except that the SAP underwriting expense ratio is based on net written premium and the underwriting expense ratio as used in this report is based on net earned premiums.
The combined ratio is an indicator of the Company’s underwriting discipline, efficiency in acquiring and servicing its business and overall underwriting profitability. A combined ratio under 100% generally indicates an underwriting profit. A combined ratio over 100% generally indicates an underwriting loss.
 Other companies’ method of computing a similarly titled measure may not be comparable to the Company’s method of computing this ratio.
Commercial multi-peril policiesRefers to policies which cover both property and third-party liability exposures.
Commutation agreementAn agreement between a reinsurer and a ceding company whereby the reinsurer pays an agreed-upon amount in exchange for a complete discharge of all obligations, including future obligations, between the parties for reinsurance losses incurred.
Core income (loss)Consolidated net income (loss) excluding the after-tax impact of net realized investment gains (losses), discontinued operations, the effect of a change in tax laws and tax rates at enactment date, and cumulative effect of changes in accounting principles when applicable. Financial statement users consider core income when analyzing the results and trends of insurance companies.
Debt-to-total capital ratioThe ratio of debt to total capitalization.
Debt-to-total capital ratio excluding net unrealized gain (loss) on investments
The ratio of debt to total capitalization excluding the after-tax impact of net unrealized investment gains and losses included in shareholders' equity.
DeductibleThe amount of loss that an insured retains.
Deferred acquisition costs (DAC)Incremental direct costs of acquired and renewal insurance contracts, consisting of commissions (other than contingent commissions) and premium-related taxes that are deferred and amortized to achieve a matching of revenues and expenses when reported in financial statements prepared in accordance with U.S. Generally Accepted Accounting Principles (GAAP).
DeficiencyWith regard to reserves for a given liability, a deficiency exists when it is estimated or determined that the reserves are insufficient to pay the ultimate settlement value of the related liabilities. Where the deficiency is the result of an estimate, the estimated amount of deficiency (or even the finding of whether or not a deficiency exists) may change as new information becomes available.
Demand surgeSignificant short-term increases in building material and labor costs due to a sharp increase in demand for those materials and services, commonly as a result of a large catastrophe resulting in significant widespread property damage.
Direct written premiumsThe amounts charged by an insurer to insureds in exchange for coverages provided in accordance with the terms of an insurance contract. The amounts exclude the impact of all reinsurance premiums, either assumed or ceded.
36


Earned premiums or premiums earned
That portion of property casualty premiums written that applies to the expired portion of the policy term. Earned premiums are recognized as revenues under both SAP and GAAP.
 Excess and surplus lines insurance
Insurance for risks not covered by standard insurance due to the unique nature of the risk. Risks could be placed in excess and surplus lines markets due to any number of characteristics, such as loss experience, unique or unusual exposures, or insufficient experience in business.  Excess and surplus lines are less regulated by the states, allowing greater flexibility to design specific insurance coverage and negotiate pricing based on the risks to be secured.
Excess liabilityAdditional casualty coverage above a layer of insurance exposures.
Excess-of-loss reinsuranceReinsurance that indemnifies the reinsured against all or a specified portion of losses over a specified dollar amount or “retention.”
ExposureThe measure of risk used in the pricing of an insurance product.  The change in exposure is the amount of change in premium on policies that renew attributable to the change in portfolio risk.
Facultative reinsuranceThe reinsurance of all or a portion of the insurance provided by a single policy. Each policy reinsured is separately negotiated.
Fair Access to Insurance Requirements (FAIR) Plan
A residual market mechanism which provides property insurance to those unable to obtain such insurance through the regular (voluntary) market. FAIR plans are set up on a state-by-state basis to cover only those risks in that state. For more information, see “residual market (involuntary business).”
Fidelity and surety programsFidelity insurance coverage protects an insured for loss due to embezzlement or misappropriation of funds by an employee. Surety is a three-party agreement in which the insurer agrees to pay a third party or make complete an obligation in response to the default, acts or omissions of an insured.
Gross written premiumsThe direct and assumed contractually determined amounts charged to the policyholders for the effective period of the contract based on the terms and conditions of the insurance contract.
Ground-up analysisA method to estimate ultimate claim costs for a given cohort of claims such as an accident year/product line component. It involves analyzing the exposure and claim activity at an individual insured level and then through the use of deterministic or stochastic scenarios and/or simulations, estimating the ultimate losses for those insureds. The total losses for the cohort are then the sum of the losses for each individual insured.
In practice, the method is sometimes simplified by performing the individual insured analysis only for the larger insureds, with the costs for the smaller insureds estimated via sampling approaches (extrapolated to the rest of the smaller insured population) or aggregate approaches (using assumptions consistent with the ground-up larger insured analysis).
Guaranteed-cost productsAn insurance policy where the premiums charged will not be adjusted for actual loss experience during the covered period.
Guaranty fundA state-regulated mechanism that is financed by assessing insurers doing business in those states. Should insolvencies occur, these funds are available to meet some or all of the insolvent insurer’s obligations to policyholders.

Lloyd’sAn insurance marketplace based in London, England, where brokers, representing clients with insurable risks, deal with Lloyd’s underwriters, who represent investors. The investors are grouped together into syndicates that provide capital to insure the risks.
LossAn occurrence that is the basis for submission and/or payment of a claim. Losses may be covered, limited or excluded from coverage, depending on the terms of the policy.
Loss adjustment expenses (LAE)The expenses of settling claims, including legal and other fees and the portion of general expenses allocated to claim settlement costs.
Loss and LAE ratioFor SAP, the loss and LAE ratio is the ratio of incurred losses and loss adjustment expenses less certain administrative services fee income to net earned premiums as defined in the statutory financial statements required by insurance regulators. The loss and LAE ratio as used in this report is calculated in the same manner as the SAP ratio.
The loss and LAE ratio is an indicator of the Company’s underwriting discipline and underwriting profitability.
Other companies’ method of computing a similarly titled measure may not be comparable to the Company’s method of computing this ratio.
Loss reservesLiabilities established by insurers and reinsurers to reflect the estimated cost of claims incurred that the insurer or reinsurer will ultimately be required to pay in respect of insurance or reinsurance it has written. Reserves are established for losses and for LAE, and consist of case reserves and IBNR reserves. As the term is used in this document, “loss reserves” is meant to include reserves for both losses and LAE.

Residual market (involuntary business)
Insurance market which provides coverage for risks for those unable to purchase insurance in the voluntary market. Possible reasons for this inability include the risks being too great or the profit potential too small under the required insurance rate structure. Residual markets are frequently created by state legislation either because of lack of available coverage such as: property coverage in a windstorm prone area or protection of the accident victim as in the case of workers’ compensation. The costs of the residual market are usually charged back to the direct insurance carriers in proportion to the carriers’ voluntary market shares for the type of coverage involved.
RetentionThe amount of exposure a policyholder company retains on any one risk or group of risks. The term may apply to an insurance policy, where the policyholder is an individual, family or business, or a reinsurance policy, where the policyholder is an insurance company.

The cost is shared by the insurance industry and self-insureds, funded through assessments to insurance companies and self-insureds based on either premiums or losses.
40


Segment income (loss)Determined in the same manner as core income (loss) on a segment basis. Management uses segment income (loss) to analyze each segment’s performance and as a tool in making business decisions. Financial statement users also consider segment income when analyzing the results and trends of insurance companies.
Self-insured retentionsThat portion of the risk retained by an insured for its own account.

SubrogationA principle of law incorporated in insurance policies, which enables an insurance company, after paying a claim under a policy, to recover the amount of the loss from another person or entity who is legally liable for it.
Tenure impactAs new business volume increases and accounts for a greater percentage of earned premiums, the loss and LAE ratio generally worsens initially, as the loss and LAE ratio for new business is generally higher than the ratio for business that has been retained for longer periods. As poorer performing business leaves and pricing segmentation improves on renewal of the business that is retained, the loss and LAE ratio is expected to improve in future years.
Third-party liabilityA liability owed to a claimant (third party) who is not one of the two parties to the insurance contract. Insured liability claims are referred to as third-party claims.
Total capitalizationThe sum of total shareholders’ equity and debt.
Treaty reinsuranceThe reinsurance of a specified type or category of risks defined in a reinsurance agreement (a “treaty”) between a primary insurer or other reinsured and a reinsurer.

UnderwriterAn employee of an insurance company who examines, accepts or rejects risks and classifies accepted risks in order to charge an appropriate premium for each accepted risk. The underwriter is expected to select business that will produce an average risk of loss no greater than that anticipated for the class of business.
UnderwritingThe insurer’s or reinsurer’s process of reviewing applications for insurance coverage, and the decision as to whether to accept all or part of the coverage and determination of the applicable premiums; also refers to the acceptance of that coverage.
Underwriting expense ratio
For SAP, the underwriting expense ratio is the ratio of underwriting expenses incurred (including commissions paid), less certain administrative services fee income and billing and policy fees, to net written premiums as defined in the statutory financial statements required by insurance regulators. The underwriting expense ratio as used in this report is the ratio of underwriting expenses (including the amortization of deferred acquisition costs), less certain administrative services fee income, billing and policy fees and other, to net earned premiums.

The underwriting expense ratio is an indicator of the Company’s efficiency in acquiring and servicing its business.
Other companies’ method of computing a similarly titled measure may not be comparable to the Company’s method of computing this ratio.
Underwriting gain or lossNet earned premiums and fee income less claims and claim adjustment expenses and insurance-related expenses.
Unearned premiumThe portion of premiums written that is allocable to the unexpired portion of the policy term.
Voluntary marketThe market in which a person seeking insurance obtains coverage without the assistance of residual market mechanisms.
Wholesale brokerAn independent or exclusive agent that represents both admitted and non-admitted insurers in market areas, which include standard, non-standard, specialty and excess and surplus lines of insurance. The wholesaler does not deal directly with the insurance consumer. The wholesaler deals with the retail agent or broker.

Item 1A. RISK FACTORS

You should carefully consider the following risks and all of the other information set forth in this report, including without limitation our consolidated financial statements and the notes thereto and "Item 7—Management's Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Estimates." The following risk factors have been organized by category for ease of use; however, many of the risks may have impacts in more than one category.

Insurance-Related Risks

High levels of catastrophe losses, including as a result of factors such as increased concentrations of insured exposures in catastrophe-prone areas and changing climate conditions, could materially and adversely affect our results of operations, our financial position and/or liquidity, and could adversely impact our ratings, our ability to raise capital and the availability and cost of reinsurance. Our property and casualty insurance operations expose us to claims arising out of catastrophes in each of the geographies where we write business and to varying peak catastrophe perils in different countries and regions. Catastrophes can be caused by various natural events, including, among others, hurricanes, tornadoes and other windstorms, earthquakes, hail, wildfires, severe winter weather, floods, tsunamis, volcanic eruptions, solar flares and other naturally-occurring events. Catastrophes can also be man-made, such as terrorist attacks and other intentionally destructive acts including those involving cyber events, nuclear, biological, chemical and radiological events, civil unrest, explosions and destruction of infrastructure.

The incidence and severity of catastrophes are inherently unpredictable, and it is possible that both the frequency and severity of natural and man-made catastrophic events could increase. Severe weather events over the last two decades have underscored the unpredictability of climate trends. For example, the frequency and/or severity of hurricane, tornado, hail and wildfire events in the United States have been more volatile during this time period. The insurance industry has experienced increased catastrophe losses due to a number of potential factors, including, in addition to weather/climate variability, aging infrastructure, more people living in, and moving to, high-risk areas, population growth in areas with weaker enforcement of building codes, urban expansion, an increase in the number of amenities included in, and the average size of, a home and higher inflation, including as a result of post-event demand surge. We believe that changing climate conditions have also likely added to the frequency and severity of natural disasters and created additional uncertainty as to future trends and exposures. Climate studies by government agencies, academic institutions, catastrophe modeling organizations and other groups indicate that an increase in the frequency and/or intensity of hurricanes, heavy precipitation events, flash flooding, sea level rise, droughts, heat waves and wildfires has occurred, and can be expected into the future. See "Item 7—Management's Discussion and Analysis of Financial Condition and Results of Operations—Catastrophe Modeling" and "—Changing Climate Conditions."

All of the catastrophe modeling tools that we use or rely on to evaluate our catastrophe exposures are based on significant assumptions and judgments and are subject to error and mis-estimation. As a result, our estimated exposures could be materially different than our actual results. See "Item 7—Management's Discussion and Analysis of Financial Condition and Results of Operations—Catastrophe Modeling" and "—Changing Climate Conditions."

The extent of losses from a catastrophe is a function of the total amount of insured exposure affected by the event, the severity of the event and the coverage provided. For example, the specific location impacted by tornadoes is inherently random and unpredictable, and the specific location impacted by a tornado may or may not be highly populated and may or may not have a high concentration of our insured exposures. Similarly, the potential for losses from a cyber event can be magnified to the extent that the event impacts geographies, platforms, systems or vulnerabilities shared by a large number of policyholders, such as cloud-based software platforms. In addition, increases in the value and geographic concentration of insured property, the number of policyholders exposed to certain events and the effects of inflation could increase the severity of claims resulting from a catastrophe. For example, in recent periods, the effects of inflation, including as a result of post-event demand surge, have increased catastrophe losses, and this could continue in the future. Disruptions to electrical power supplies have also increased losses arising from natural events, a dynamic which may become more frequent as dependency on electricity increases and/or if the reliability of the electric grid decreases.

States have from time to time passed legislation, and regulators have taken action, that have the effect of limiting the ability of insurers to manage catastrophe risk, such as by restricting insurers from reducing exposures or withdrawing from catastrophe-prone areas or mandating that insurers participate in residual markets. Residual markets have resulted in, and may in the future
43


result in, significant losses or assessments to insurers, including us. In addition, legislative, regulatory and legal actions have sought to expand insurance coverage for catastrophe claims beyond the original intent of the policies, prevent the application of deductibles or limit other rights of insurers. We may not be able to adjust terms or adequately raise prices to offset the costs of catastrophes. See "Item 1—Business—U.S. State and Federal Regulation – Regulatory and Legislative Responses to Catastrophes.”

The estimation of claims and claim adjustment expense reserves related to catastrophe losses can be affected by, among other things, the nature of the information available at the time of estimation, coverage issues, and legal, regulatory and economic uncertainties. The estimates related to catastrophe losses are adjusted in subsequent periods as actual claims emerge and additional information becomes available, and these adjustments could be material.

Exposure to catastrophe losses could adversely affect our financial strength and claims-paying ratings and could impair our ability to raise capital on acceptable terms or at all. Also, as a result of our exposure to catastrophe losses, rating agencies may further increase capital requirements, which may require us to raise capital to maintain our ratings. A ratings downgrade could hurt our ability to compete effectively or attract new business. In addition, catastrophic events could cause us to exhaust our available reinsurance limits and could adversely impact the cost and availability of reinsurance on a going-forward basis. Such events can also impact the credit of our reinsurers. For a discussion of our catastrophe reinsurance coverage, see "Item 1—Business—Reinsurance—Catastrophe Reinsurance." Catastrophic events could also adversely impact the credit of the issuers of securities held in our investment portfolio, such as states or municipalities.

In addition, coverage in our reinsurance program for terrorism is limited. Although the Terrorism Risk Insurance Program provides benefits in the event of certain acts of terrorism, those benefits are subject to a deductible and other limitations, and the program is scheduled to expire on December 31, 2027. Under current provisions of this program, once our losses exceed 20% of our eligible direct commercial earned premiums for the preceding calendar year, the federal government will reimburse us for 80% of our losses attributable to certain acts of terrorism which exceed this deductible up to a total industry program cap of $100 billion. Our estimated deductible under the program is $3.15 billion for 2023. For a further description of the Terrorism Risk Insurance Program, see note 6 of the notes to the consolidated financial statements.

Because of the risks set forth above, catastrophes could materially and adversely affect our results of operations, financial position and/or liquidity. Further, we may not have sufficient resources to respond to claims arising from a high frequency of high-severity natural catastrophes and/or of man-made catastrophic events involving conventional means or claims arising out of one or more man-made catastrophic events involving “unconventional” means, such as nuclear, biological, chemical or radiological events.

If actual claims exceed our claims and claim adjustment expense reserves, or if changes in the estimated level of claims and claim adjustment expense reserves are necessary, including as a result of, among other things, changes in the legal/tort, regulatory and economic environments in which the Company operates, our financial results could be materially and adversely affected. Claims and claim adjustment expense reserves (“loss reserves”) represent management estimates of what the ultimate settlement and administration of claims will cost, generally utilizing actuarial expertise and projection techniques, at a given accounting date. The process of estimating loss reserves involves a high degree of judgment and is subject to a number of variables. These variables can be affected by both internal and external events, such as: changes in claims handling procedures, including automation; adverse changes in loss cost trends, including inflationary pressures, technology or other changes that may impact medical, auto and home repair costs (e.g., more costly technology in vehicles, labor shortages, higher costs of used vehicles and parts, and increased demand and decreased supply for raw materials, all of which results in increased severity of claims); economic conditions, including general and wage inflation; legal trends, including adverse changes in the tort environment that have continued to persist at elevated levels for a number of years (e.g., increased and more aggressive attorney involvement in insurance claims, increased litigation, expanded theories of liability, higher jury awards, lawsuit abuse and third-party litigation finance, among others); labor shortages, which can result in companies hiring less experienced workers; and legislative changes, among others. The impact of many of these items on ultimate costs for loss reserves could be material and is difficult to estimate, particularly in light of the recent disruptions to the judicial system, supply chain and labor market. For example, the ongoing backlog of cases in the courts due to shutdowns related to COVID-19 has resulted in claims being unresolved for longer periods of time, which the Company believes has contributed, and will continue to contribute, to increased loss costs. Loss reserve estimation difficulties also differ significantly by product line due to differences in claim complexity, the volume of claims, the potential severity of individual claims, the determination of occurrence date for a claim and lags in reporting of events to insurers, among other factors.

The increase in inflation in recent periods has significantly increased our loss costs in our auto and property businesses. It is possible that inflation could remain at high levels for a prolonged period, or increase from these high levels, which could in turn lead to further increases in our loss costs. The impact of inflation on loss costs could be more pronounced for those lines of
44


business that are considered “long tail,” such as general liability and workers' compensation, as they require a relatively long period of time to finalize and settle claims for a given accident year or require payouts over a long period of time. In addition, a significant portion of claims costs, including those in “long tail” lines of business, consists of medical costs. As a result, an increase in medical inflation could materially and adversely impact our loss costs and our claims and claim adjustment expense reserves. Recent changes in the macroeconomic environment have impacted medical labor and materials costs, the potential persistency of which could result in future loss costs which are higher than our current expectations. In addition to the impact of inflation on reserves, on a going forward basis, we may not be able to offset the impact of inflation on our loss costs with sufficient price increases. The estimation of loss reserves may also be more difficult during extreme events, such as a pandemic, or during volatile or uncertain economic conditions, due to unexpected changes in behavior of claimants and policyholders, including an increase in fraudulent reporting of exposures and/or losses, reduced maintenance of insured properties, increased frequency of small claims or delays in the reporting or adjudication of claims.

We refine our loss reserve estimates as part of a regular, ongoing process as historical loss experience develops, additional claims are reported and settled, and the legal, regulatory and economic environment evolves. Business judgment is applied throughout the process, including the application of various individual experiences and expertise to multiple sets of data and analyses. Different experts may apply different assumptions and judgments when faced with material uncertainty, based on their individual backgrounds, professional experiences and areas of focus. As a result, these experts may at times produce estimates materially different from each other. This risk may be exacerbated in the context of an extreme event or an acquisition. Experts providing input to the various estimates and underlying assumptions include actuaries, underwriters, claim personnel and lawyers, as well as other members of management. Therefore, management often considers varying individual viewpoints as part of its estimation of loss reserves.

Due to the inherent uncertainty underlying loss reserve estimates, the final resolution of the estimated liability for claims and claim adjustment expenses will likely be higher or lower than the related loss reserves at the reporting date. In addition, our estimate of claims and claim adjustment expenses may change. These additional liabilities or increases in estimates, or a range of either, could vary significantly from period to period and could materially and adversely affect our results of operations and/or our financial position. For a discussion of loss reserves by product line, including examples of common factors that can affect reserves, see "Item 7—Management's Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Estimates—Claims and Claim Adjustment Expense Reserves."

Our business could be harmed because of our potential exposure to asbestos and environmental claims and related litigation. We continue to receive a significant number of asbestos claims. Factors underlying these claim filings include continued intensive advertising by lawyers seeking asbestos claimants and the continued focus by plaintiffs on defendants, such as manufacturers of talcum powder, who were not traditionally primary targets of asbestos litigation. We also continue to be involved in coverage litigation concerning a number of policyholders, some of whom have filed for bankruptcy, who in some instances have asserted that all or a portion of their asbestos-related claims are not subject to aggregate limits on coverage and/or that each individual bodily injury claim should be treated as a separate occurrence under the policy. To the extent both issues are resolved in a policyholder’s favor and our other defenses are not successful, our coverage obligations under the policies at issue would be materially increased and bounded only by the applicable per-occurrence limits and the number of asbestos bodily injury claims against the policyholders. Although we have seen a moderation in the overall risk associated with these lawsuits, it remains difficult to predict the ultimate cost of these claims. Further, in addition to claims against policyholders, proceedings have been launched directly against insurers, including us, by individuals challenging insurers’ conduct with respect to the handling of past asbestos claims and by individuals seeking damages arising from alleged asbestos-related bodily injuries. It is possible that the filing of other direct actions against insurers, including us, could be made in the future.

We also continue to receive claims from policyholders who allege that they are liable for injury or damage arising out of their alleged disposition of toxic substances. Liability for investigation and cleanup of environmental contamination and for some related losses under federal laws, such as the Comprehensive Environmental Response, Compensation and Liability Act, and under similar state laws, may be imposed on certain parties even if they did not cause the release or threatened release of hazardous substances and may be joint and several with other responsible parties.

The Company has been, and continues to be, involved in litigation involving insurance coverage issues pertaining to asbestos and environmental claims. The Company believes that some court decisions have interpreted the insurance coverage to be broader than the original intent of the insurers and policyholders. These decisions continue to be inconsistent and vary from jurisdiction to jurisdiction. Uncertainties surrounding the final resolution of these asbestos and environmental claims continue, and it is difficult to estimate our ultimate liability for such claims and related litigation. As a result, these reserves are subject to revision as new information becomes available and as claims develop. It is also not possible to predict changes in the legal, regulatory and legislative environment and their impact on the future development of asbestos and environmental claims. This environment could be affected by changes in applicable legislation and future court and regulatory decisions and interpretations,
45


including the outcome of legal challenges to legislative and/or judicial reforms establishing medical criteria for the pursuit of asbestos claims. It is also difficult to predict the ultimate outcome of complex coverage disputes until settlement negotiations near completion and significant legal questions are resolved or, failing settlement, until the dispute is adjudicated. This is particularly the case with policyholders in bankruptcy where negotiations often involve a large number of claimants and other parties and require court approval to be effective.

It is possible that the outcome of the continued uncertainties regarding these claims could result in liability in future periods that differs from current reserves by an amount that could materially and adversely affect our results of operations. See the "Asbestos Claims and Litigation," "Environmental Claims and Litigation" and “Uncertainty Regarding Adequacy of Asbestos and Environmental Reserves” sections of "Item 7—Management's Discussion and Analysis of Financial Condition and Results of Operations." Also see "Item 3—Legal Proceedings."

We are exposed to, and may face adverse developments involving, mass tort claims such as those relating to exposure to potentially harmful products or substances. We face potential exposure to mass tort claims, including claims related to exposure to potentially harmful products or substances, such as lead paint, perfluoroalkyl and polyfluoroalkyl substances (PFAS), talc and opioids. Establishing loss reserves for mass tort claims is subject to significant uncertainties because of many factors, including adverse changes to the tort environment that have continued to persist at elevated levels for a number of years (e.g., increased and more aggressive attorney involvement in insurance claims, increased litigation, expanded theories of liability, higher jury awards, lawsuit abuse and third-party litigation finance, among others); evolving judicial interpretations, including application of various theories of joint and several liabilities; disputes concerning medical causation with respect to certain diseases; geographical concentration of the lawsuits asserting the claims; and the potential for a large rise in the total number of claims without underlying epidemiological developments suggesting an increase in disease rates. Because of the uncertainties set forth above, additional liabilities may arise for amounts in excess of the current loss reserves. In addition, our estimate of loss reserves may change. These additional liabilities or increases in estimates, or a range of either, could vary significantly from period to period and could materially and adversely affect our results of operations and/or our financial position.

The effects of emerging claim and coverage issues on our business are uncertain, and court decisions or legislative changes that take place after we issue our policies can result in an unexpected increase in the number of claims and have a material adverse impact on our results of operations. As industry practices and legal, judicial, social and other environmental conditions change, unexpected and unintended issues related to claim and coverage may emerge. These issues may adversely affect our business, including by extending coverage beyond our underwriting intent, by increasing the number, size or types of claims or by mandating changes to our underwriting practices. Examples of such claims and coverage issues include, but are not limited to:

judicial expansion of policy coverage and the impact of new or expanded theories of liability;
plaintiffs targeting insurers in purported class action litigation relating to claims handling and other practices;
claims relating to construction defects, which often present complex coverage and damage valuation questions;
claims related to data and network security breaches, information system failures or cyber events, including cases where coverage was not intended to be provided;
the assertion of “public nuisance” or similar theories of liability, pursuant to which plaintiffs, including governmental entities, seek to recover monies spent to respond to harm caused to members of the public, abate hazards to public health and safety and/or recover expenditures purportedly attributable to a “public nuisance,” such as litigation against manufacturers or distributors of lead paint, opioids, perfluoroalkyl and polyfluoroalkyl substances (PFAS) and other allegedly harmful products, and entities that caused or contributed to harm to the environment;
claims related to liability, business interruption or workers’ compensation arising out of infectious disease or pandemic;
claims related to vaccine mandates, testing protocols or other matters related to employees returning to the workplace;
claims relating to abuse by an employee or a volunteer of an insured;
claims that link health issues to particular causes (for example, cumulative traumatic head injury from sports or other causes), resulting in liability or workers’ compensation claims;
claims alleging that one or more of our underwriting criteria have a disparate impact on persons belonging to a protected class in violation of the law, including the Fair Housing Act;
claims arising out of modern techniques and practices used in connection with the extraction of natural resources, such as hydraulic fracturing or wastewater injection;
claims arising out of the use of personal property in commercial transactions, such as ride or home sharing;
claims against fiduciaries of retirement plans, including allegations regarding excessive fees;
claims under laws protecting biometric data;
46


claims relating to unanticipated consequences of current or new technologies or business models or processes, including as a result of related behavioral changes; and
claims relating to changing climate conditions, including claims alleging that our policyholders cause or contribute to changing climate conditions.

In some instances, emerging issues may not become apparent for some time after we have issued the affected insurance policies. As a result, the full extent of liability under our insurance policies may not be known for many years after the policies are issued.

In addition, the passage of new legislation designed to expand the right to sue, to remove limitations on recovery, to deem by statute the existence of a covered occurrence, to extend or eliminate the statutes of limitations or otherwise to repeal or weaken tort reforms could have a material and adverse effect on our results of operations. For example, over the past few years, a number of states have enacted legislation allowing victims of sexual molestation to file or proceed with claims that otherwise would have been time-barred and additional states are considering similar legislative changes.

The effects of these and other unforeseen emerging claim and coverage issues are extremely hard to predict and could harm our business and materially and adversely affect our results of operations.

Financial, Economic and Credit Risks

During or following a period of financial market disruption or an economic downturn, our business could be materially and adversely affected. If financial markets experience significant disruption or if economic conditions deteriorate, such as in a period of recession or stagflation, our results of operations, financial position and/or liquidity likely would be adversely impacted. For example, financial market disruptions and economic downturns in the past have resulted in, among other things, reduced business volume, heightened credit risk, reduced valuations for certain of our investments and heightened vulnerability for smaller vendors with whom we do business. Future actions or inactions of the United States government related to the “debt-ceiling” could increase the actual or perceived risk that the United States may not ultimately pay its obligations when due. This could result in downgrades to the credit rating of the United States and potential disruption to financial markets, including capital markets.

Several of the risk factors discussed above and below identify risks that could result from, or be exacerbated by, financial market disruption, an economic slowdown or economic uncertainty. These include risks discussed above related to our estimates of claims and claim adjustment expense reserves and emerging claim and coverage issues, and those discussed below related to our investment portfolio, the competitive environment, reinsurance arrangements, other credit exposures, regulatory developments and the impact of rating agency actions. See also "Item 7—Management's Discussion and Analysis of Financial Condition and Results of Operations," particularly the "Outlook" section, for additional information about these risks and the potential impact on our business.

Our investment portfolio is subject to credit and interest rate risk, and may suffer reduced or low returns or material realized or unrealized losses. Investment returns are an important part of our overall profitability. Fixed maturity and short-term investments comprised approximately 93% of the carrying value of our investment portfolio as of December 31, 2022. Changes in interest rates affect the carrying value of our fixed maturity investments and returns on our fixed maturity and short-term investments. A decline in interest rates reduces the returns available on short-term investments and new fixed maturity investments (including those purchased to re-invest maturities from the existing portfolio), thereby negatively impacting our net investment income on a going-forward basis, while rising interest rates reduce the market value of existing fixed maturity investments, thereby negatively impacting our book value, as we experienced in 2022. While interest rates have risen rapidly during 2022, they continue to remain at low levels relative to historical experience, and rates may remain at low levels relative to historical experience for a prolonged period. See also “Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations—Outlook.” The value of our fixed maturity and short-term investments is also subject to the risk that certain investments may default or become impaired due to a deterioration in the financial condition of one or more issuers of the securities held in our portfolio, or due to a deterioration in the financial condition of an insurer that guarantees an issuer’s payments of such investments. Such defaults and impairments could reduce our net investment income and result in realized investment losses. During an economic downturn, fixed maturity and short-term investments could be subject to a higher risk of default, and our non-fixed income investments could be negatively impacted as well.

A significant portion of our fixed maturity investment portfolio is invested in obligations of states, municipalities and political subdivisions. This municipal bond portfolio could be subject to default or impairment. In particular:

47


Many state and local governments have from time to time operated under deficits or projected deficits, particularly during and after a financial market disruption or economic downturn. The severity and duration of these deficits could have an adverse impact on the collectability and valuation of our municipal bond portfolio. These deficits may also be exacerbated by the impact of unfunded pension plan obligations and other postretirement obligations or by declining municipal tax bases and revenues in times of financial stress.

Some municipal bond issuers may be unwilling to increase tax rates, or to reduce spending, to fund interest or principal payments on their municipal bonds, or may be unable to access the municipal bond market to fund such payments. The risk of widespread defaults may increase if some issuers voluntarily choose to default, instead of implementing difficult fiscal measures, and the actual or perceived consequences are less severe than expected.

The risk of widespread defaults may also increase if there are changes in legislation that permit states, municipalities and political subdivisions to file for bankruptcy protection where they were not permitted before. In addition, the collectability and valuation of municipal bonds may be adversely affected if there are judicial interpretations in a bankruptcy or other proceeding that lessen the value of structural protections. For example, debtors may challenge the effectiveness of structural protections thought to be provided by municipal securities backed by a dedicated source of revenue. The collectability and valuation may also be adversely affected if there are judicial interpretations in a bankruptcy or other proceeding that question the payment priority of municipal bonds.

Our portfolio has benefited from tax exemptions (such as those related to interest from municipal bonds) and certain other tax laws, including, but not limited to, those governing dividends-received deductions and tax credits. Changes in these laws could adversely impact the value of our investment portfolio.

Our investment portfolio includes: residential mortgage-backed securities; collateralized mortgage obligations; pass-through securities and asset-backed securities collateralized by sub-prime mortgages; commercial mortgage-backed securities; and wholly-owned real estate and real estate partnerships, all of which could be adversely impacted by declines in real estate valuations, including as a result of changes in the use of commercial office and retail space since the COVID-19 pandemic.

We also invest a portion of our assets in equity securities, private equity limited partnerships, hedge funds and real estate partnerships. From time to time, we may also invest in other types of non-fixed maturity investments, including investments with exposure to commodity price risk. All of these asset classes are subject to greater volatility in their investment returns than fixed maturity investments. General economic and market conditions, changes in applicable tax laws and many other factors beyond our control can adversely affect the value of our non-fixed maturity investments and the realization of net investment income, and/or result in realized investment losses. As a result of these factors, we may realize reduced returns on these investments, incur losses on sales of these investments and be required to write down the value of these investments, which could reduce our net investment income and result in realized investment losses. From time to time, the Company enters into short positions in U.S. Treasury futures contracts to manage the duration of its fixed maturity portfolio, which can result in realized investment losses.

Our investment portfolio is also subject to increased valuation uncertainties when investment markets are illiquid. The valuation of investments is more subjective when markets are illiquid, thereby increasing the risk that the estimated fair value (i.e., the carrying amount) of the portion of the investment portfolio that is carried at fair value as reflected in our financial statements is not reflective of prices at which actual transactions could occur.

We may, depending on circumstances in the future, including as a result of changes in economic and market conditions, make changes to the mix of investments in our investment portfolio as part of our ongoing efforts to seek appropriate risk-adjusted returns. These changes may impact the duration, volatility and risk of our investment portfolio.

Because of the risks set forth above, the value of our investment portfolio could decrease, we could experience reduced net investment income and we could experience realized and/or unrealized investment losses, which could materially and adversely affect our results of operations, financial position and/or liquidity.

We may not be able to collect all amounts due to us from reinsurers, reinsurance coverage may not be available to us in the future at commercially reasonable rates or at all and we are exposed to credit risk related to our structured settlements. Although the reinsurer is liable to us to the extent of the reinsurance, we remain liable as the direct insurer on all risks reinsured. As a result, reinsurance arrangements do not eliminate our obligation to pay claims. Accordingly, we are subject to credit risk with respect to our ability to recover amounts due from reinsurers. In the past, certain reinsurers have ceased writing business and entered into runoff. Some of our reinsurance claims may be disputed by the reinsurers, and we may ultimately receive partial or no payment. This is a particular risk in the case of claims that relate to insurance policies written
48


many years ago, including those relating to asbestos and environmental claims. In addition, in a number of jurisdictions a reinsurer is permitted to transfer a reinsurance arrangement to another reinsurer, which may be less creditworthy, without a counterparty’s consent. Also, the reinsurance that we purchase may not cover all of the risks covered by the policies that we issue.

Included in reinsurance recoverables are amounts related to certain structured settlements. Structured settlements are annuities purchased from various life insurance companies to settle certain personal physical injury claims, of which workers’ compensation claims comprise a significant portion. In cases where we did not receive a release from the claimant, the structured settlement is included in reinsurance recoverables and the related claim cost is included in the liability for loss reserves, as we retain the contingent liability to the claimant. Some of the life insurance companies from which we have purchased annuities have been downgraded to below investment grade credit ratings subsequent to the time of the purchase. If it is expected that the life insurance company is not able to pay, we would recognize an impairment of the related reinsurance recoverable if, and to the extent, the purchased annuities are not covered by state guaranty associations. In the event that the life insurance company fails to make the required annuity payments, we would be required to make such payments. For a discussion of the top five providers of our reinsurance and structured settlements, see "Item 7—Management's Discussion and Analysis of Financial Condition and Results of Operations—Reinsurance Recoverables."

Both the availability of reinsurance capacity and its cost can be impacted, and in recent periods have been impacted, by general economic conditions and conditions in the reinsurance market, such as the occurrence of significant reinsured events or unexpected adverse trends. The availability and cost of reinsurance could affect our business volume and profitability. In addition, the Covered Agreements between the U.S. and each of the EU and U.K. eliminate the requirement for European and U.K. reinsurers operating in the U.S. to provide collateral, which could make it more difficult for U.S. companies, including us, to obtain collateral from European and U.K. reinsurers.

Because of the risks set forth above, we may not be able to collect all amounts due to us from reinsurers, and reinsurance coverage may not be available to us in the future at commercially reasonable rates or at all, and/or life insurance companies may fail to make required annuity payments, and thus our results of operations could be materially and adversely affected.

We are exposed to credit risk in certain of our insurance operations and with respect to certain guarantee or indemnification arrangements that we have with third parties. We are exposed to credit risk in several areas of our business operations, including credit risk relating to policyholders, independent agents and brokers. To a significant degree, the extent of the credit risk that we face is a function of the health of the economy; accordingly, we face an increased credit risk in an economic downturn.

We are exposed to credit risk in our surety insurance operations, where we guarantee to a third party that our customer will satisfy certain performance obligations (e.g., a construction contract) or certain financial obligations, including exposure to large customers who may have obligations to multiple third parties. If our customer defaults, we may suffer losses and not be reimbursed by that customer, even though we are entitled to indemnification from such customer. In addition, it is customary practice for multiple insurers to participate as co-sureties on large surety bonds. Under these arrangements, the co-surety obligations are typically joint and several, in which case we are also exposed to credit risk with respect to our co-sureties.

In addition, a portion of our business is written with large deductible insurance policies. Under casualty insurance contracts with deductible features, we are obligated to pay the claimant the full amount of the settled claim. We are subsequently reimbursed by the contractholder for the deductible amount, and, as a result, we are exposed to credit risk to the policyholder. Moreover, certain policyholders purchase retrospectively rated policies (i.e., where premiums are adjusted after the policy period based on the actual loss experience of the policyholder during the policy period). Retrospectively rated policies expose us to additional credit risk to the extent that the adjusted premium is greater than the original premium.

Our efforts to mitigate the credit risk that we have to our insureds may not be successful. For example, we may not be able to obtain collateral and any collateral obtained may subsequently have little or no value.

In accordance with industry practice, when policyholders purchase insurance policies from us through independent agents and brokers, the premiums relating to those policies are often paid to the agents and brokers for payment to us. In most jurisdictions, the premiums will be deemed to have been paid to us whether or not they are actually received by us. Consequently, we assume a degree of credit risk associated with amounts due from independent agents and brokers.

We are also exposed to credit risk related to certain guarantee or indemnification arrangements that we have with third parties. See note 17 of the notes to the consolidated financial statements. Our exposure to the above credit risks could materially and adversely affect our results of operations.

A downgrade in our claims-paying and financial strength ratings could adversely impact our business volumes, adversely impact our ability to access the capital markets and increase our borrowing costs. Claims-paying and financial strength ratings are important to an insurer’s competitive position. A downgrade in one or more of our ratings could negatively impact our business volumes or make it more difficult or costly for us to access the capital markets or borrow money. If significant losses, including, but not limited to, those resulting from one or more major catastrophes, or significant reserve additions or significant investment losses were to cause our capital position to deteriorate significantly, or if one or more rating agencies substantially increase their capital requirements, we may need to raise equity capital in the future (which we may not be able to do at a reasonable cost or at all, especially at a time of financial market disruption) in order to maintain our ratings or limit the extent of a downgrade. A continued trend of more frequent and severe catastrophes or a prolonged financial market disruption or economic downturn may lead rating agencies to substantially increase their capital requirements. Furthermore, S&P has proposed changes to its capital model that could adversely impact such agency's assessment of capital adequacy for participants in the insurance industry, including the Company. See also "Item 1—Business—Ratings."

The inability of our insurance subsidiaries to pay dividends to our holding company in sufficient amounts would harm our ability to meet our obligations, pay future shareholder dividends and/or make future share repurchases. Our holding company relies on dividends from our U.S. insurance subsidiaries to meet our obligations for payment of interest and principal on outstanding debt, to pay dividends to shareholders, to make contributions to our qualified domestic pension plan, to pay other corporate expenses and to make share repurchases. The ability of our insurance subsidiaries to pay dividends to our holding company in the future will depend on their statutory capital and surplus, earnings and regulatory restrictions.

We are subject to state insurance regulation as an insurance holding company system. Our U.S. insurance subsidiaries are subject to various regulatory restrictions that limit the maximum amount of dividends available to be paid to their parent without prior approval of insurance regulatory authorities. In a time of prolonged economic downturn or otherwise, insurance regulators may choose to further restrict the ability of insurance subsidiaries to make payments to their parent companies. The ability of our insurance subsidiaries to pay dividends to our holding company is also restricted by regulations that set standards of solvency that must be met and maintained.

The inability of our insurance subsidiaries to pay dividends to our holding company in an amount sufficient to meet our debt service obligations and other cash requirements could harm our ability to meet our obligations, to pay future shareholder dividends and to make share repurchases.

Business and Operational Risks

The ongoing impact of COVID-19 and related risks, and any future pandemics (including new variants of COVID-19), could materially affect our results of operations, financial position and/or liquidity. While the Company believes that many of the risks related to COVID-19 have moderated, some significant risks remain, such as inflation; supply chain disruption; labor shortages; backlogs in the court system (which increase the time and costs to resolve claims); regulators rejecting rate increases in the face of claim frequency rates returning to pre-pandemic levels and increased severity due to inflation; behavioral changes that began to manifest during the pandemic and have continued, such as driving at faster speeds, which have resulted in the increased frequency and severity of claims; “long-COVID” and other claims in our workers compensation line; and litigation seeking business interruption coverage. Risks related to future pandemics (including new variants of COVID-19) include, in addition to those discussed above, reduced earned premiums; higher claim and claim adjustment expenses in certain lines of business; adverse legislative or regulatory actions; operational disruptions; increased general and administrative expenses; financial market disruption; and an economic downturn. These risks could materially and adversely impact our results of operations, financial position and/or liquidity. For a further discussion of risks that can impact us as a result of financial market disruption or an economic downturn, see “During or following a period of financial market disruption or an economic downturn, our business could be materially and adversely affected” above and “Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations—Outlook.”

The intense competition that we face, including with respect to attracting and retaining employees, and the impact of innovation, technological change and changing customer preferences on the insurance industry and the markets in which we operate, could harm our ability to maintain or increase our business volumes and our profitability. The property and casualty insurance industry is highly competitive, and we believe that it will remain highly competitive for the foreseeable future. We compete with both domestic and foreign insurers, including start-ups, which may offer products at prices and on terms that are not consistent with our economic standards in an effort to maintain or increase their business. The competitive environment in which we operate could also be impacted by current general economic conditions, which could reduce the volume of business available to us as well as to our competitors. Pension and hedge funds and other entities with substantial available capital, more flexible legal structures and/or potentially lower return objectives have increasingly sought to participate in the property and casualty insurance and reinsurance businesses. Well-capitalized new entrants to the property and
50


casualty insurance and reinsurance industries and existing competitors that receive substantial infusions of capital may conduct business in ways that adversely impact our business volumes and profitability. In addition, the competitive environment could be impacted by changes in customer preferences, including customer demand for direct distribution channels and/or greater choice, not only in personal lines, but also in commercial lines (where direct writers may become a more significant source of competition in the future, particularly in the small commercial market). Similarly, comparative rating technology has impacted competition in personal lines and is now being used to access comparative rates for small commercial business as well, and that trend is likely to continue and may accelerate. In recent years, there have been new entrants into the small commercial business, and this trend may continue. Customer behavior could also evolve in the future towards buying insurance in point-of-sale or other non-traditional distribution channels where we may not have a meaningful presence or which are designed to sell products that we currently do not provide. Consolidation within the insurance industry also could impact our business volumes and/or the rates or terms of our products.

Other technological changes also present competitive risks. For example, our competitive position could be impacted if we are unable to deploy, in a cost effective and competitive manner, technology such as artificial intelligence and machine learning that collects and analyzes a wide variety of data points (so-called “big data” analysis) to make underwriting or other decisions, or if our competitors collect and use data which we do not have the ability to access or use. In addition, innovations, such as telematics and other usage-based methods of determining premiums, can impact product design and pricing and are becoming an increasingly important competitive factor.

Competitive dynamics may impact the success of efforts to improve our underwriting margins on our insurance products. These efforts could include seeking improved rates or improved terms and conditions, and could also include other initiatives, such as reducing operating expenses and acquisition costs. These efforts may not be successful and/or may result in lower business volumes. In addition, if our underwriting is not effective, further efforts to increase rates could also lead to “adverse selection”, whereby accounts retained have higher losses, and are less profitable, than accounts lost. For more detail, see "Item 7—Management's Discussion and Analysis of Financial Condition and Results of Operations—Outlook."

Similar to other industries, the insurance industry is undergoing rapid and significant technological and other change. Traditional insurance industry participants, technology companies, “InsurTech” start-up companies, the number of which has increased significantly in recent years and some of which are supported by traditional insurance industry participants, and others are focused on using technology and innovation to simplify and improve the customer experience, increase efficiencies, redesign products, alter business or distribution models and effect other potentially disruptive changes in the insurance industry. If we do not anticipate, keep pace with and adapt to technological and other changes impacting the insurance industry, it will harm our ability to compete, decrease the value of our products to customers, and materially and adversely affect our business. Furthermore, innovation, technological change and changing customer preferences in the markets in which we operate also pose risks to our business. For example, technologies such as driverless vehicles, assisted-driving or accident prevention technologies, technologies that facilitate ride, car or home sharing, smart homes or automation could reduce the number of vehicles in use and/or the demand for, or profitability of, certain of our products, create coverage issues or impact the frequency or severity of losses, and we may not be able to respond effectively. While there is substantial uncertainty as to the timing of any impact, in the case of driverless vehicles in particular, new legal frameworks or business practices could be adopted that reduce the size of the auto insurance market. If competition or technological or other changes to the markets in which we operate limit our ability to retain existing business or write new business at adequate rates or on appropriate terms, our results of operations could be materially and adversely affected. See "Competition" sections of the discussion on business segments in "Item 1—Business." Technological change can impact us in other ways as well. For example, rapid changes in the sophistication and use of certain types of cyber-attacks, such as ransomware and social engineering attacks, on our insureds have increased the frequency and severity of losses under our policies. The risk of cyber attacks could be exacerbated by geopolitical tensions, including hostile actions taken by nation-states and terrorist organizations.

There is significant competition from within the property and casualty insurance industry and from businesses outside the industry for qualified employees, especially those in key positions and those possessing highly specialized knowledge in areas such as underwriting, data and analytics, technology and e-commerce. This competition has increased in recent periods and, with the increase in remote work, is taking place on a broader geographic scale. In addition, the competition for talent and the difficulty in attracting and retaining employees has also increased due to the increase in the number of individuals exiting the workforce since the onset of the pandemic and to the retirement of members of the “baby boomer” generation. This dynamic has also impacted our agents, brokers, regulators, vendors and other business partners. If we and our business partners are not able to successfully attract, train, retain and motivate our respective employees, our business, financial results and reputation could be materially and adversely affected.

51


Disruptions to our relationships with our independent agents and brokers or our inability to manage effectively a changing distribution landscape could adversely affect us. We market our insurance products primarily through independent agents and brokers. An important part of our business is written through less than a dozen such intermediaries, including the agency affiliate of GEICO, with whom we have had a distribution arrangement for homeowners' business since 1995. Further, there has been a trend of increased consolidation by agents and brokers, which could impact our relationships with, and fees paid to, some agents and brokers, and/or otherwise negatively impact the pricing or distribution of our products. Agents and brokers may increasingly compete with us to the extent that markets increasingly provide them with direct access to providers of capital seeking exposure to insurance risk or if they become affiliated with carriers that compete with us. In all of the foregoing situations, loss of all or a substantial portion of the business provided through such agents and brokers could materially and adversely affect our future business volume and results of operations.

Our efforts or the efforts of agents and brokers with respect to new products or markets, alternate distribution channels, changes to commission terms as well as changes in the way agents and brokers utilize data and technology, including in ways that may be in direct competition with us, could adversely impact our business relationship with independent agents and brokers who currently market our products, resulting in a lower volume and/or profitability of business generated from these sources.

In certain markets, brokers increasingly have been packaging portfolios of risks together and offering them to fewer carriers. In these and other situations, agents and brokers have an increased influence over policy language and compensation structure which, if we participate on that basis, could adversely impact our ability to profitably manage underwriting risk. It could also lead to commoditization of products, which could increase the focus on price and cost management and decrease our ability to differentiate our products in the marketplace with customers based on other factors.

Customers in the past have brought claims against us for the actions of our agents. Even with proper controls in place, actual or alleged errors or inaccuracies by our agents could result in our involvement in disputes, litigation or regulatory actions.

Our efforts to develop new products or services, expand in targeted markets, improve business processes and workflows or make acquisitions may not be successful and may create enhanced risks. From time to time, to protect and grow market share and/or improve our productivity and efficiency, we invest in strategic initiatives and pursue acquisitions. These efforts may require us to make substantial expenditures and not be successful, and even if successful, they may create additional risks:

Changes to our business processes or workflow, including the use of new technologies, may give rise to execution risk;
Models underlying automated underwriting and pricing decisions may not be effective;
Demand for new products or expansion into new markets may not meet our expectations;
New products or services and expansion into new markets may change our risk exposures, and the data and models we use to manage such exposures may not be as effective as those we use in existing markets or with existing products;
Acquisitions may not be successfully integrated, resulting in substantial disruption, costs or delays and adversely affecting our ability to compete, and may also result in unforeseen liabilities or impact our credit ratings; and
In connection with the conversion of policyholders to a new product, some policyholders’ pricing may increase while the pricing for other policyholders may decrease, the net impact of which could negatively impact retention and profit margins.

These efforts may require us to make substantial expenditures, which may negatively impact results in the near term, and if not successful, could materially and adversely affect our results of operations.

We may be adversely affected if our pricing and capital models provide materially different indications than actual results. Our profitability substantially depends on the extent to which our actual claims experience is consistent with the assumptions we use in pricing our policies. We utilize proprietary and third-party models to help us price business in a manner that is intended to be consistent, over time, with actual results and return objectives. We incorporate our historical loss experience, external industry and other data, and economic indices into our modeling processes, and we use various methods, including predictive modeling, forecasting and sophisticated simulation modeling techniques, to analyze loss trends and the risks associated with our assets and liabilities. We also use these modeling processes, analyses and methods in making underwriting, pricing and reinsurance decisions as part of managing our exposure to catastrophes and other extreme adverse events. These modeling processes incorporate numerous assumptions and forecasts about the future level and variability of the frequency and severity of losses, inflation, interest rates and capital requirements, among others, that are difficult to make and may differ materially from actual results. In addition, as the number of third-party models increases, it becomes more difficult to validate, manage and integrate such models as they evolve over time, and the risk associated with assimilating the output from such models into our decisions increases.

If we fail to appropriately price the risks we insure or fail to change our pricing models to appropriately reflect our experience, or if our claims experience is more frequent or severe than our underlying risk assumptions, for example due to inflation,
52


changing climate conditions, legislative or regulatory changes, changes in behavior such as distracted or faster driving or a more aggressive tort environment, our profit margins may be negatively affected. If we underestimate the frequency and/or severity of extreme adverse events occurring, our financial condition may be adversely affected. If we overestimate the risks we are exposed to, we may overprice our products, and new business growth and retention of our existing business may be adversely affected. See "Item 7—Management's Discussion and Analysis of Financial Condition and Results of Operations—Catastrophe Modeling."

We are subject to additional risks associated with our business outside the United States. We conduct business outside the United States primarily in Canada, the United Kingdom and the Republic of Ireland. In addition, we conduct business in Brazil and Colombia through joint ventures. We may also explore opportunities in other countries. In conducting business outside of the United States, we are subject to a number of risks, particularly in emerging economies. These risks include restrictions such as price controls, capital controls, currency exchange limits, ownership limits and other restrictive or anti-competitive governmental actions or requirements, which could have an adverse effect on our business and our reputation. A portion of our premiums from outside of the United States is generated in Canada, a substantial portion of which consists of automobile premiums from the province of Ontario, which is a highly regulated market that can result in rate inadequacy. Our business activities outside the United States may also subject us to currency risk and, in some markets, it may be difficult to effectively hedge that risk, or we may choose not to hedge that risk. In addition, in some markets, we invest as part of a joint venture with a local counterparty. Because our governance rights may be limited, we may not have control over the ability of the joint venture to make certain decisions and/or mitigate risks it faces, and significant disagreements with a joint venture counterparty may adversely impact our investment and/or reputation. Our business activities outside the United States could subject us to increased volatility in earnings resulting from the need to recognize and subsequently revise a valuation allowance associated with income taxes if we became unable to fully utilize any deferred tax assets, including loss carry-forwards from those foreign operations. Also, political instability and geopolitical tensions could result in financial market disruption or an economic downturn in such regions. The U.K.'s withdrawal from the European Union, for example, has by some estimates resulted in reduced trade levels in the U.K. In addition, supply chain disruptions and the war in Ukraine have resulted in increased inflation and reduced growth in the U.K. and the European Union. For certain specialty business, we give managing general agents binding authority, which exposes us to additional risks.

Our business activities outside the United States also subject us to additional domestic and foreign laws and regulations, including the Foreign Corrupt Practices Act and similar laws in other countries that prohibit the making of improper payments to foreign officials. Although we have policies and controls in place that are designed to ensure compliance with these laws, if those controls are ineffective and/or an employee or intermediary fails to comply with applicable laws and regulations, we could suffer civil and criminal penalties and our business and our reputation could be adversely affected. Some countries, particularly emerging economies, have laws and regulations that lack clarity and, even with local expertise and effective controls, it can be difficult to determine the exact requirements of, and potential liability under, the local laws. In some jurisdictions, including Brazil, parties to a joint venture may, in some circumstances, have liability for some obligations of the venture, and that liability may extend beyond the capital invested. Failure to comply with local laws in a particular market may result in substantial liability and could have a significant and negative effect not only on our business in that market but also on our reputation generally.

Loss of or significant restrictions on the use of particular types of underwriting criteria, such as credit scoring, or other data or methodologies, in the pricing and underwriting of our products could reduce our future profitability. Our underwriting profitability depends in large part on our ability to competitively price our products at a level that will adequately compensate us for the risks assumed. As a result, risk selection and pricing through the application of actuarially sound and segmented underwriting criteria is critical. However, laws or regulations, or judicial or administrative findings, could significantly curtail the use of particular types of underwriting criteria. For example, we may use credit scoring as a factor in pricing decisions where allowed by state law. Some consumer groups and/or regulators have alleged that the use of credit scoring violates the law by discriminating against persons belonging to a protected class and are calling for the prohibition or restrictions on the use of credit scoring in underwriting and pricing. A variety of other underwriting criteria and other data or methodologies used in personal and commercial insurance have been and continue to be criticized by regulators, government agencies, consumer groups or individuals on similar or other grounds, such as the impact of external data sources, artificial intelligence, algorithms and predictive models on protected classes of customers, and a number of states have begun rulemaking efforts in response or are considering doing so. Resulting legislative or regulatory actions or litigation could result in negative publicity and/or generate adverse rules or findings, such as curtailing the use of important underwriting criteria, or other data or methodologies, which could materially and adversely affect our results of operations.

53


Technology and Intellectual Property Risks

Our business success and profitability depend, in part, on effective information technology systems and on continuing to develop and implement improvements in technology, particularly as our business processes become more digital. We depend in large part on our technology systems for conducting business and processing claims, as well as for providing the data and analytics we utilize to manage our business. As a result, our business success is dependent on maintaining the effectiveness of existing technology systems and on continuing to develop and enhance technology systems that support our business processes and strategic initiatives in an efficient manner, particularly as our business processes become more digital and certain of our products, such as cyber insurance, are more technology-based. Some system development projects are long-term in nature, may negatively impact our expense ratios as we invest in the projects and may cost more than we expect to complete. In addition, system development projects may not deliver the benefits or perform as expected, or may be replaced or become obsolete more quickly than expected, which could result in operational difficulties, additional costs or accelerated recognition of expenses. Attracting and retaining technology personnel has also become significantly more challenging in recent periods. If we do not effectively and efficiently manage and upgrade our technology portfolio, or if the costs of doing so are higher than we expect, our ability to provide competitive services to, and conduct business with, new and existing customers in a cost effective manner and our ability to implement our strategic initiatives could be adversely impacted.

If we experience difficulties with technology, data and network security (including as a result of cyber attacks), outsourcing relationships or cloud-based technology, our ability to conduct our business could be negatively impacted. A shut-down of, or inability to access, one or more of our facilities (including our primary data processing facility); a power outage; or a failure of one or more of our systems could significantly impair our ability to perform necessary business functions on a timely basis. In the event of a computer virus or natural or other disaster, our systems could be inaccessible for an extended period of time, including as a result of hostile actions taken by nation-states or terrorist organizations. In addition, because our systems increasingly interface with and depend on third-party systems, including cloud-based, we could experience service denials or failures of controls if demand for our service exceeds capacity or a third-party system fails or experiences an interruption. Business interruptions and failures of controls could also result if our internal systems do not interface with each other as intended or if changes to such systems or our other business processes, such as new payment technologies, are not effectively implemented. Business continuity can also be disrupted by an event, such as a pandemic, that renders large numbers of a workforce unable to work as needed, particularly at critical locations. If our business continuity plans do not sufficiently address a business interruption, system failure or service denial, this could result in a deterioration of our ability to write and process new and renewal business, provide customer service, pay claims in a timely manner or perform other necessary business functions. In addition, should internet disruptions occur, or frustration with our business platforms or distribution initiatives develop among our independent agents and brokers, any resulting loss of business could materially and adversely affect our future business volume and results of operations.

Our operations rely on the secure processing, storage and transmission of confidential and other information in our computer systems and networks. Computer viruses, hackers and employee or vendor misconduct, and other external hazards (such as social engineering attacks), could expose our data systems to security breaches, cyber-attacks or other disruptions. Increased use of data supplied by third parties in our business increases our exposure to this risk. While we attempt to develop secure transmission capabilities with third-party vendors and others with whom we do business, we may not be successful and, in addition, these third parties may not have appropriate controls in place to protect the confidentiality of the information.

Like other global companies, our computer systems are regularly subject to and will continue to be the target of computer viruses, malware or other malicious codes (including ransomware), unauthorized access, cyber-attacks or other computer-related penetrations. The Company, like other property and casualty insurers, may be under greater threat from cybercriminals seeking sensitive personal or other insurance-related information. The risk of cyber attacks could be exacerbated by geopolitical tensions, including hostile actions taken by nation-states or terrorist organizations.

While we have experienced cyber-attacks, to date, we are not aware that we have experienced a material cyber-security breach. The sophistication of these threats continues to increase, and the preventative actions we take to reduce the risk of cyber incidents and protect our systems and information may be insufficient. In addition, new technology that could result in greater operational efficiency may further expose our computer systems to the risk of cyber-attacks. Also, our increased use of open source software, cloud technology and software as a service can make it more difficult to identify and remedy such situations due to the disparate location of code utilized in our operations.

We have outsourced certain technology and business process functions to third parties and may increasingly do so in the future. If we do not effectively develop, implement and monitor our vendor relationships, if third party providers do not perform as anticipated, if we experience technological or other problems with a transition, or if vendor relationships relevant to our business process functions are terminated, we may not realize expected productivity improvements or cost efficiencies and may
54


experience operational difficulties, increased costs and a loss of business. Our outsourcing of certain technology and business process functions to third parties may expose us to increased risk related to data and cyber security, service disruptions or the effectiveness of our control system. These risks could increase as additional functions move to the cloud and as dependencies and interconnections with the third parties with whom we do business increase.

The increased risks identified above could expose us to data loss or manipulation, disruption of service, monetary and reputational damages, competitive disadvantage and significant increases in compliance costs and costs to improve the security and resiliency of our computer systems. The compromise of personal, confidential or proprietary information could also subject us to legal liability or regulatory action under evolving cyber-security, data protection and privacy laws and regulations enacted by the U.S. federal and state governments, Canada, the European Union or other jurisdictions or by various regulatory organizations or exchanges. As a result, our ability to conduct our business and our results of operations might be materially and adversely affected.

Intellectual property is important to our business, and we may be unable to protect and enforce our own intellectual property or we may be subject to claims for infringing the intellectual property of others. Our success depends in part upon our ability to protect our proprietary trademarks, technology and other intellectual property. See "Item 1—Business—Other Information—Intellectual Property." We may not, however, be able to protect our intellectual property from unauthorized use and disclosure by others. Further, the intellectual property laws may not prevent our competitors from independently developing trademarks, products and services that are similar to ours. We may incur significant costs in our efforts to protect and enforce our intellectual property, including the initiation of expensive and protracted litigation, and we may not prevail. Any inability to enforce our intellectual property rights could have a material adverse effect on our business and our ability to compete.

We may be subject to claims by third parties from time to time that our products, services and technologies infringe on their intellectual property rights. In recent years, certain entities have acquired patents in order to allege claims of infringement against companies, including in some cases, us. Any intellectual property infringement claims brought against us could cause us to spend significant time and money to defend ourselves, regardless of the merits of the claims. If we are found to infringe any third-party intellectual property rights, it could result in reputational harm, payment of significant monetary damages or fees and/or substantial time and expense to redesign our products, services or technologies to avoid the infringement. In addition, we use third-party software in some of our products, services and technologies. If any of our software vendors or licensors are faced with infringement claims, we may lose our ability to use such software until the dispute is resolved. If we cannot successfully redesign an infringing product, service or technology (or procure a substitute version), this could have a material adverse effect on our business and ability to compete.

Regulatory and Compliance Risks

Our businesses are heavily regulated by the states and countries in which we conduct business, including licensing, market conduct and financial supervision, and changes in regulation, including higher tax rates, may reduce our profitability and limit our growth. These regulatory systems are generally designed to protect the interests of policyholders, and not necessarily the interests of insurers, their shareholders and other investors. For example, to protect policyholders whose insurance company becomes financially insolvent, guaranty funds have been established in all 50 states to pay the covered claims of policyholders in the event of an insolvency of an insurer, subject to applicable state limits. The funding of guaranty funds is provided through assessments levied against remaining insurers in the marketplace. As a result, the insolvency of one or more insurance companies or an increase in amounts paid by guaranty funds could result in additional assessments levied against us.

These regulatory systems also address authorization for lines of business, statutory capital and surplus requirements, limitations on the types and amounts of certain investments, underwriting limitations, transactions with affiliates, dividend limitations, changes in control, premium rates and a variety of other financial and non-financial components of an insurer’s business including, recently, cyber-security. In addition, many jurisdictions restrict the timing and/or the ability of an insurer to discontinue writing a line of business or to cancel or non-renew certain policies. Insurance regulators may also increase the statutory capital and surplus requirements for our insurance subsidiaries or, as has happened recently in certain states, reject rate increases or other terms and conditions due to the economic environment or other factors. In addition, state tax laws that specifically impact the insurance industry, such as premium taxes, or more general tax laws, such as U.S. federal corporate taxes, could be enacted or changed and could have a material adverse impact on us. Other legislative actions could impact our business as well. For example, changes to state law regarding workers' compensation insurance could impact the demand for our products, and the legalization of cannabis in certain states has, according to some studies, resulted in more automobile accidents. In addition, the potential repeal of the McCarran-Ferguson Act (which exempts insurance from most federal regulation) or a change to the federal health care system that eliminates or reduces the need for the medical coverage
55


component of workers' compensation insurance, could also significantly harm the insurance industry, including us. Changes in applicable legislation and regulations and future court and regulatory decisions may be more restrictive and may result in lower revenues and/or higher costs of compliance and, as a result, could materially and adversely affect our results of operations. See also “Item 1 – Business – Regulation.”

We could be adversely affected if our controls designed to ensure compliance with guidelines, policies and legal and regulatory standards are not effective. Our business is highly dependent on our ability to engage on a real-time basis in a large number of insurance underwriting, claim processing, treasury and investment activities, many of which are highly complex and constantly evolving, including from a systems perspective. These activities often are subject to internal guidelines and policies, as well as legal and regulatory standards. A control system, no matter how well designed and operated, can provide only reasonable assurance that the control system’s objectives will be met. If our controls, or the controls of our joint ventures or recently acquired businesses, are not effective (including with respect to the prevention or identification of misconduct by employees or others with whom we do business), it could lead to financial loss, unanticipated risk exposure (including underwriting, credit and investment risk), errors in financial reporting, litigation, regulatory proceedings or damage to our reputation.

The Company’s Board of Directors has approved common share repurchase authorizations under which repurchases may be made from time to time in the open market, pursuant to pre-set trading plans meeting the requirements of Rule 10b5-1 under the Securities Exchange Act of 1934, in private transactions or otherwise. The most recent authorization was approved by the Board of Directors on April 20, 2021 and added $5.0 billion of repurchase capacity to the $805 million capacity remaining at that date. The authorizations do not have a stated expiration date. The timing and actual number of shares to be repurchased in the future will depend on a variety of factors, including the Company’s financial position, earnings, share price, catastrophe losses, maintaining capital levels appropriate for the Company’s business operations, changes in levels of written premiums, funding of the Company’s qualified pension plan, capital requirements of the Company’s operating subsidiaries, legal requirements, regulatory constraints, other investment opportunities (including mergers and acquisitions and related financings), market conditions, changes in tax laws (including the Inflation Reduction Act) and other factors.

The Company acquired 6,366 shares for a total cost of approximately $1 million during the three months ended December 31, 2022 that were not part of the publicly announced share repurchase authorization. These shares consisted of shares retained to cover payroll withholding taxes in connection with the vesting of restricted stock unit awards and performance share awards, and shares used by employees to cover the price of certain stock options that were exercised.

For additional information regarding the Company's share repurchases, see "Item 7—Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources."
Information relating to compensation plans under which the Company's equity securities are authorized for issuance is set forth in "Part III—Item 12" of this Report.

The following discussions of the Company’s net income and segment income (loss) are presented on an after-tax basis.  Discussions of the components of net income and segment income (loss) are presented on a pre-tax basis, unless otherwise noted.  Discussions of earnings per common share are presented on a diluted basis.

Overview
Diluted net income per share of $11.77 in 2022 decreased by 19% from diluted net income per share of $14.49 in 2021. Net income of $2.84 billion in 2022 decreased by 22% from net income of $3.66 billion in 2021. The lower rate of decrease in diluted net income per share reflected the impact of share repurchases in recent periods. The decrease in income before income taxes primarily reflected the pre-tax impacts of (i) lower net investment income, (ii) net realized investment losses compared to net realized investment gains in 2021 and (iii) lower underwriting margins excluding catastrophe losses and prior year reserve development ("underlying underwriting margins"), partially offset by (iv) higher net favorable prior year reserve development. Net favorable prior year reserve development in 2022 and 2021 was $649 million and $538 million, respectively. Catastrophe losses in 2022 and 2021 were $1.88 billion and $1.85 billion, respectively. The lower underlying underwriting margins in 2022 were driven by Personal Insurance, partially offset by Business Insurance and Bond & Specialty Insurance. Underlying underwriting margins in 2021 reflected a net favorable impact associated with the pandemic. Income tax expense in 2022 was lower than in 2021, primarily reflecting the impact of the decrease in income before income taxes and a $47 million reduction in income tax expense in the first quarter of 2022 as a result of the resolution of prior year tax matters.

The Company has insurance operations in Canada, the United Kingdom, the Republic of Ireland and throughout other parts of the world as a corporate member of Lloyd’s, as well as in Brazil and Colombia, primarily through joint ventures. Because these operations are conducted in local currencies other than the U.S. dollar, the Company is subject to changes in foreign currency exchange rates. For the years ended December 31, 2022 and 2021, changes in foreign currency exchange rates had the impact of lowering the reported line items in the statement of income by insignificant amounts. The impact of these changes was not material to the Company’s net income or segment income for the periods reported.

Revenues
Earned Premiums
Earned premiums in 2022 were $33.76 billion, $2.91 billion or 9% higher than in 2021. In Business Insurance, earned premiums in 2022 increased by 9% over 2021. Earned premiums in Business Insurance in 2021 were negatively impacted by lower net written premiums primarily in the latter half of 2020 due to a modest reduction in exposures and a decrease in new business volume, in each case impacted by COVID-19 and related economic conditions. In Bond & Specialty Insurance, earned premiums in 2022 increased by 9% over 2021. In Personal Insurance, earned premiums in 2022 increased by 11% over 2021. Earned premiums in Bond & Specialty Insurance and Personal Insurance in 2021 were not materially impacted by COVID-19 and related economic conditions. Factors contributing to the change in earned premiums in each segment in 2022 as compared with 2021 are discussed in more detail in the segment discussions that follow.

Net investment income in 2022 was $2.56 billion, $471 million or 16% lower than in 2021. Net investment income from fixed maturity investments in 2022 was $2.11 billion, $124 million higher than in 2021. The increase primarily resulted from a higher average level of fixed maturity investments and higher average yields. Net investment income from short-term securities in 2022 was $73 million, $66 million higher than in 2021. The increase primarily resulted from higher short-term average yields, partially offset by a lower level of short-term investments. The Company's remaining investment portfolios had net investment income of $419 million in 2022, $658 million lower than in 2021, primarily reflecting the impact of lower returns from private equity partnerships as compared to very strong returns in 2021. Included in other investments are private equity, hedge fund and real estate partnerships that are accounted for under the equity method of accounting and typically report their financial statement information to the Company one month to three months following the end of the reporting period. Accordingly, net investment income from these other investments is generally reflected in the Company's financial statements on a quarter lag basis.

Fee Income
Fee income in 2022 was $412 million, $10 million higher than in 2021. The National Accounts market in Business Insurance is the primary source of the Company’s fee-based business and is discussed in the Business Insurance segment discussion that follows.

Net Realized Investment Gains (Losses)
The following table sets forth information regarding the Company’s net pre-tax realized investment gains (losses).

Total$(204)$171 $
Net realized investment losses on equity securities still held of $61 million in 2022 were driven by the impact of changes in fair value attributable to unfavorable equity markets. Net realized investment gains on equity securities still held of $78 million in 2021 were driven by the impact of changes in fair value attributable to favorable equity markets.
Other net realized investment losses in 2022 included $72 million of net realized investment losses related to fixed maturity investments, $8 million of net realized investment losses related to equity securities sold and $25 million of net realized investment losses related to other investments. Other net realized investment gains in 2021 included $69 million of net realized investment gains related to fixed maturity investments, $17 million of net realized investment gains related to equity securities sold and $9 million of net realized investment gains related to other investments.
Other Revenues
Other revenues in 2022 were $351 million, $4 million lower than 2021. Other revenues include revenues from Simply Business, installment premium charges and other policyholder service charges. Other revenues from Simply Business were negatively impacted by changes in foreign currency exchange rates.
Claims and Expenses
Claims and Claim Adjustment Expenses
Claims and claim adjustment expenses in 2022 were $22.85 billion, $2.56 billion or 13% higher than 2021, primarily reflecting the impacts of (i) higher business volumes, (ii) loss cost trends, including elevated losses in both the automobile and homeowners and other product lines in Personal Insurance and (iii) favorable loss activity associated with the pandemic in 2021 in Business Insurance, partially offset by (iv) higher net favorable prior year reserve development. Catastrophes in 2022 primarily resulted from a significant winter storm that impacted most of the U.S. and parts of Canada and Hurricanes Ian and Fiona, as well as severe wind and hail storms in several regions of the United States. Catastrophes in 2021 primarily resulted from winter storms, Hurricane Ida, tornado activity in Kentucky and severe wind and hail storms in several regions of the United States, as well as a wildfire in Colorado. Catastrophe and non-catastrophe weather-related losses in 2021 were reduced by the full $350 million of recoveries available under the Company's 2021 Underlying Property Aggregate Catastrophe Excess-of-Loss Reinsurance Treaty.

Factors contributing to net favorable prior year reserve development during the years ended December 31, 2022, 2021 and 2020 are discussed in more detail in note 8 of the notes to the consolidated financial statements.
Significant Catastrophe Losses
The Company defines a “catastrophe” as an event:
that is designated a catastrophe by internationally recognized organizations that track and report on insured losses resulting from catastrophic events, such as Property Claim Services (PCS) for events in the United States and Canada; and
for which the Company’s estimates of its ultimate losses before reinsurance and taxes exceed a pre-established dollar threshold.
62


The Company’s threshold for disclosing catastrophes is primarily determined at the reportable segment level. If a threshold for one segment or a combination thereof is exceeded and the other segments have losses from the same event, losses from the event are identified as catastrophe losses in the segment results and for the consolidated results of the Company. Additionally, an aggregate threshold is applied for International business across all reportable segments. The threshold for 2022 ranged from approximately $20 million to $30 million of losses before reinsurance and taxes.

The following table presents the amount of losses recorded by the Company for significant catastrophes that occurred in 2022, 2021 and 2020, the amount of net unfavorable (favorable) prior year reserve development recognized in 2022 and 2021 for catastrophes that occurred in 2021 and 2020, and the estimate of ultimate losses for those catastrophes at December 31, 2022, 2021 and 2020. For purposes of the table, a significant catastrophe is an event for which the Company estimates its ultimate losses will be $100 million or more after reinsurance and before taxes.
