ITEM 1.    BUSINESS

General

We are a leading provider of private passenger automobile, commercial automobile, and homeowners insurance in Massachusetts. In addition to these coverages, we offer a portfolio of other insurance products, including dwelling fire, umbrella and business owner policies. Operating exclusively in Massachusetts, New Hampshire and Maine through our insurance company subsidiaries, Safety Insurance Company ("Safety Insurance"), Safety Indemnity Insurance Company ("Safety Indemnity"), and Safety Property and Casualty Insurance Company ("Safety P&C") (together referred to as the "Insurance Subsidiaries"), we have established strong relationships with independent insurance agents, who numbered 871 in 1,095 locations throughout these three states during 2020. We have used these relationships and, in particular, our extensive knowledge of the Massachusetts market to become the third largest private passenger automobile carrier and the second largest commercial automobile carrier in Massachusetts, capturing an approximate 8.4% and 12.8% share, respectively, of the Massachusetts private passenger and commercial automobile markets in 2020 according to statistics compiled by Commonwealth Automobile Reinsurers ("CAR"). We also are the third largest homeowners insurance carrier in Massachusetts with a 7.0% share of that market. We were ranked the 53^rd largest automobile writer in the country according to S&P Global Market Intelligence, based on 2019 direct written premiums. We were incorporated under the laws of Delaware in 2001, but through our predecessors, we have underwritten insurance in Massachusetts since 1979.

Our Insurance Subsidiaries began writing insurance in New Hampshire during 2008 and Maine in 2016. The table below shows the amount of direct written premiums written in each state during the years ended December 31, 2020, 2019, and 2018.

	Years Ended December 31,
Direct Written Premiums	2020		2019		2018
Massachusetts	$	764,479	$	819,534	$	813,857
New Hampshire		32,334		31,676		29,159
Maine		1,899		1,194		659
Total	$	798,712	$	852,404	$	843,675

In November of 2020, we formed a fourth insurance subsidiary, Safety Northeast Insurance Company (“Safety Northeast”, which became licensed to write insurance products in Massachusetts in January of 2021.

Our Competitive Strengths

We Have Strong Relationships with Independent Agents. In 2020, independent agents accounted for approximately 58.1% of the Massachusetts automobile insurance market measured by direct written premiums as compared to approximately 30.8% nationwide, based on data made available by Independent Insurance Agents and Brokers of America, Inc. and Commonwealth Automobile Reinsurers. For that reason, our strategy is centered around, and we sell exclusively through, a network of independent agents. In order to support our independent agents and enhance our relationships with them, we:

● provide our agents with a portfolio of property and casualty insurance products at competitive prices to help them effectively address the insurance needs of their clients;

● provide our agents with a variety of technological resources which enable us to deliver superior service and support to them; and

● offer our agents competitive commission schedules and profit sharing programs.

Through these measures, we strive to become the preferred provider of the independent agents in our agency network and capture a growing share of the total insurance business written by these agents in Massachusetts, New Hampshire and Maine. We must compete with other insurance carriers for the business of independent agents.

We Have a History of Profitable Operations.  In 39 out of 40 years since our inception in 1979, we have been profitable. We have achieved our profitability, among other things, by:

● operating as the third largest private passenger auto premium insurance carrier, the second largest commercial auto insurance carrier, and third largest homeowner insurance carrier in Massachusetts. We have maintained direct written premiums in a competitive market over the last five years seeing total direct written premium of $798,712 in 2020 compared to $811,559 in 2016. During the year ended December 31, 2020, as a result of the COVID-19 pandemic, the Company instituted the Safety Personal Auto Relief Credit, a 15% policyholder credit, representing $17,711 in total premium which was applied to personal auto policies for the months of April, May and June which impacted the 2020 direct written premiums by that amount. Overall, outside of this relief credit, our direct written premium has increased over this five year period.

● maintaining a combined ratio that is typically below industry averages (refer to Insurance Ratios under Item 7—Management's Discussion and Analysis of Financial Condition and Results of Operations for a discussion on insurance ratios);

● taking advantage of the institutional knowledge our management has amassed during its long tenure in the industry;

● introducing new lines and forms of insurance products;

● investing in technology to simplify internal processes and enhance our relationships with our agents; and

● maintaining a high-quality investment portfolio.

We Have Developed Advanced Technology for Our Business.  We have dedicated significant human and financial resources to the development of advanced information systems. Our technology efforts have benefited us in two distinct ways. First, we continue to develop technology that empowers our independent agent customers by making it easier for them to transact business with their clients and with the Insurance Subsidiaries. In our largest business line, private passenger automobile insurance, our agents submit approximately 99.0% of all applications for new policies or endorsements for existing policies to us electronically through our proprietary information portal, the Agents Virtual Community ("AVC"). Our agents also can submit commercial automobile and homeowners insurance policies electronically over the AVC. Second, our investment in technology has allowed us to re-engineer internal back office processes to provide more efficient service at a lower cost.

2

We Have an Experienced, Committed and Knowledgeable Management Team. Our senior management team has an average of over 24 years of experience with Safety and a demonstrated ability to operate successfully within the property and casualty market.

Our Strategy

To achieve our goal of increasing shareholder value, our strategy is to maintain and develop strong independent agent relationships by providing our agents with a full package of insurance products and information technology services. We believe this strategy will allow us to:

● further penetrate the Massachusetts, New Hampshire and Maine markets in all lines of business;

● implement rates, forms and billing options that allow us to cross-sell private passenger automobile, homeowners, dwelling fire, and personal umbrella policies in the personal lines market and commercial automobile, business owner policies, commercial property package and commercial umbrella policies in the commercial lines market in order to capture a larger share of the total Massachusetts, New Hampshire and Maine property and casualty insurance business written by each of our independent agents; and

● continue to expand our technology to enable independent agents to more easily serve their customers and conduct business with us, thereby strengthening their relationships with us.

Property and Casualty Insurance Market

Introduction.  We are licensed by the respective state insurance departments to transact property and casualty insurance in Massachusetts, New Hampshire, and Maine. All of our business is regulated by these departments, with the most extensive oversight from our domestic regulator, the Massachusetts Division of Insurance.

Products

Historically, we have focused on underwriting private passenger automobile insurance, which is written through our subsidiary, Safety Insurance. In 1989, we formed Safety Indemnity to offer commercial automobile insurance at preferred rates. Since 1997, we have expanded the breadth of our product line in order for agents to address a greater portion of their clients' insurance needs by selling multiple products. Homeowners, business owner, personal umbrella, dwelling fire and commercial umbrella insurance policies are written by Safety Insurance at standard rates and written by Safety Indemnity at preferred rates. In December 2006, we formed Safety P&C to offer homeowners and commercial automobile insurance at ultra preferred rates. In November 2020, we formed Safety Northeast to offer a fourth homeowners rate level for risks that satisfy stricter underwriting guidelines. We expect to begin writing policies through Safety Northeast in 2021.

The table below shows our premiums in each of these product lines for the periods indicated and the portions of our total premiums each product line represented.

Our product lines are as follows:

Private Passenger Automobile (54.9% of 2020 direct written premiums).  Private passenger automobile insurance is our primary product. These policies provide coverage for bodily injury and property damage to others, no-fault personal injury coverage for the insured/insured's car occupants, and physical damage coverage for an insured's own vehicle for collision or other perils.

Commercial Automobile (14.9% of 2020 direct written premiums).  Commercial automobile policies provide coverage for bodily injury and property damage to others, no-fault personal injury coverage, and physical damage coverage for an insured's own vehicle for collision or other perils resulting from the ownership or use of commercial vehicles in a business. We offer insurance for commercial vehicles used for business purposes such as private passenger-type vehicles, trucks, tractors and trailers (excluding long-haul trucking), and insure individual vehicles as well as commercial fleets.

Homeowners (25.0% of 2020 direct written premiums).  We offer a broad selection of coverage forms for qualified policyholders. Homeowners policies provide coverage for losses to a dwelling and its contents from numerous perils, and coverage for liability to others arising from ownership or occupancy. We write policies on homes, condominiums, and apartments.

Business Owner Policies (2.8% of 2020 direct written premiums).  We serve eligible small and medium sized commercial accounts with a program that covers apartments and residential condominiums; mercantile establishments, including limited cooking restaurants; offices, including office condominiums; processing and services businesses; special trade contractors; and wholesaling businesses. Business owner policies provide liability and property coverage for many perils, including business interruption from a covered loss. Equipment breakdown coverage is automatically included, and a wide range of additional coverage is available to qualified customers. We write policies for business owners at standard rates with qualifying risks eligible for preferred lower rates.

Personal Umbrella (1.0% of 2020 direct written premiums). We offer personal excess liability coverage over and above the limits of individual automobile, watercraft, and homeowner's insurance policies to clients. We write policies at standard rates with limits of $1,000 to $5,000.

Dwelling Fire (1.3% of 2020 direct written premiums).  We underwrite dwelling fire insurance, which is a limited form of a homeowner's policy for non-owner occupied residences. We write all forms of dwelling fire coverage at standard rates with qualifying risks eligible for preferred lower rates.

Commercial Umbrella (0.1% of 2020 direct written premiums).  We offer an excess liability product to clients for whom we underwrite both commercial automobile and business owner policies. The program is directed at commercial automobile risks with private passenger-type automobiles or light and medium trucks. We write commercial umbrella policies at standard rates with limits ranging from $1,000 to $5,000.

Inland Marine (Included in our Homeowners direct written premiums).  We offer inland marine coverage as an endorsement for all homeowners and business owner policies, and as part of our commercial package policy. Inland marine provides additional coverage for jewelry, fine arts and other items that a homeowners or business owner policy would limit or not cover. Scheduled items valued at more than $5 must meet our underwriting guidelines and be appraised.

Watercraft (Included in our Homeowners direct written premiums). We offer watercraft coverage for small and medium sized pleasure craft with maximum lengths of 32 feet, valued at less than $75 and maximum speed of 39 knots. We write this coverage as an endorsement to our homeowner's policies.

4

The insurance industry can also be impacted by terrorism, and we have filed and received approval for a number of terrorism endorsements, which limit our liability and property exposure according to the Terrorism Risk Insurance Act of 2002, the Terrorism Risk Insurance Extension Act of 2005, the Terrorism Risk Insurance Program Reauthorization Act of 2007, the Terrorism Risk Insurance Program Reauthorization of 2015 and the Terrorism Risk Insurance Program Reauthorization Act of 2019. See "Reinsurance," discussed below.

Distribution

We distribute our products exclusively through independent agents, unlike some of our competitors who use multiple distribution channels. We believe this gives us a competitive advantage with the agents. With the exception of personal automobile business assigned to us by the Massachusetts Automobile Insurance Plan (“MAIP”) or written through CAR’s commercial automobile Servicing Carrier program, we do not accept business from insurance brokers. Our voluntary agents have authority pursuant to our voluntary agency agreement to bind our Insurance Subsidiaries for any coverage that is within the scope of their authority. We reserve the ability to cancel any coverage bound, in accordance with applicable law. In total, our independent agents numbered 871 and had 1,095 offices (some agencies have more than one office) and approximately 9,476 customer service representatives during 2020.

Voluntary Agents.  In 2020, we obtained approximately 96.2% of our direct written premiums for automobile insurance and 100% of our direct written premiums for all of our other lines of business through our voluntary agents. As of December 31, 2020, we had agreements with 740 voluntary agents. Our voluntary agents are located in all regions of Massachusetts, New Hampshire and Maine.

We look for agents with profitable portfolios of business. To become a voluntary agent for our Company, we generally require that an agency: (i) have been in business for at least five years; (ii) have exhibited a three year private passenger average ratio of losses, excluding loss adjustment expenses, to net earned premiums ("pure loss ratio") of 65.0% or less on the portion of the agent's portfolio that we would underwrite; (iii) make a commitment for us to underwrite at least 300 policies from the agency during the first twelve months after entering an agreement with us; and (iv) offer multiple product lines. Every year, we review the prior year performance of our agents. If an agent fails to meet our profitability standards, we try to work with the agent to improve the profitability of the business it places with us. We generally terminate contracts each year with a few agencies, which, despite our efforts, have been consistently unable to meet our standards. Although independent agents usually represent several unrelated insurers, our goal is to be one of the top two insurance companies represented in each of our agencies, as measured by direct written premiums. No individual agency generated more than 8.8% of our direct written premiums in 2020.

Massachusetts law guarantees that CAR provides motor vehicle insurance coverage to all eligible risks. Under the MAIP, personal automobile policies are assigned to us for three years, unless the policyholder is offered a voluntary policy by another insurer. All Massachusetts agents are authorized to submit eligible business to the MAIP for random assignment to a carrier such as Safety Insurance. We are allocated all private passenger residual market business through the MAIP.

CAR runs a reinsurance pool for ceded commercial automobile policies through the Commercial Automobile Program (the “Commercial Automobile Program”).  CAR has appointed Safety and three other servicing carriers to process ceded commercial automobile insurance.  Safety was reappointed for this program on January 1, 2017 for an additional five-year term.  Approximately $174,400 of ceded premium is spread equitably among the four servicing carriers.  Subject to the review of the Massachusetts Commissioner of Insurance (“the Commissioner”), CAR sets the premium rates for commercial automobile policies reinsured through CAR and this reinsurance pool can generate an underwriting result that is a profit or deficit based upon CAR's rate level.  This underwriting result is allocated among every Massachusetts commercial automobile insurance company, including us, based on a company's commercial automobile voluntary market share.

5

CAR also runs a reinsurance pool for Taxi, Limousine and Car Service risks (the "Taxi/Limo Program"). CAR reappointed Safety as one of the two servicing carriers for this program on January 1, 2017 for an additional five-year term. Approximately $5,520 of ceded premium was spread equitably between the two servicing carriers.

We are assigned independent agents by CAR who can submit commercial business to us in the Commercial Automobile Program and the Taxi/Limo Program, and we classify those agents as Exclusive Representative Producers (“ERPs”).

In 2020, the COVID-19 pandemic had an impact on our voluntary exposure counts as some of our independent agency partners were forced to close during the year, affecting normal new business production. In addition, the 2020 commercial automobile exposures decreased when compared to the prior year as a result of a redistribution of agents among Servicing Carriers in the CAR Commercial Auto Program as well as changes made by CAR to eligibility requirements which impacted the number of policies that we handle as a Servicing Carrier.

In 2020, 66.1% of the private passenger automobile exposures we insure had an other than private passenger policy with us, compared to 64.2% and 61.7% in 2019 and 2018, respectively. In addition, 82.8% of our homeowners’ policyholders had a matching automobile policy with us in 2020 compared to 82.5% in 2019 and 81.9% in 2018.

Marketing

We view the independent agent as our customer and business partner. As a result, a component of our marketing efforts focuses on developing interdependent relationships with leading Massachusetts, New Hampshire and Maine agents that write profitable business and positioning ourselves as the preferred insurance carrier of those agents, thereby receiving a larger portion of each agent's aggregate business. Our principal marketing strategies to agents are:

● to offer a range of products, which we believe enables our agents to meet the insurance needs of their clients;

● to price our products competitively, including offering discounts when and where appropriate for safer drivers for our personal automobile products, loss-free credits for our homeowner products and also offering account discounts for policyholders that have more than one policy with us;

6

● to design, price and market our products to our agents for their customers to place all their insurance with us;

● to offer agents competitive commissions, with incentives for placing their more profitable business with us; and

● to provide a level of support and service that enhances the agent's ability to do business with its clients and with us.

We have a comprehensive branding campaign using a variety of radio, television, digital and print advertisements.

Commission Schedule and Profit Sharing Plan.  We have several programs designed to attract profitable new business from agents by paying them competitive commissions. We recognize our top performing agents by making them members of either our Chairman's Elite, Chairman's, President's, Executive's or Preferred Agent's Club. In 2020, members of these Clubs received a commission of up to 18.0% of premiums for each new private passenger auto policy, up to 22.0% of premiums for each new homeowner policy, up to 20.0% for each new commercial auto policy and up to 20.0% for each new commercial property policy.

Further, we have a competitive agency incentive commission program under which we pay agents up to 7.5% of premiums based on the loss ratio on their business.

Service and Support. We believe that the level and quality of service and support we provide helps differentiate us from other insurers. We have made a significant investment in information technology designed to facilitate our agents' business. Our AVC website helps agents manage their work efficiently. We provide a substantial amount of information online that agents need to serve their customers, such as information about the status of new policies, bill payments and claims. Providing this type of content reduces the number of customer calls we receive and empowers the agent's customer service representatives by enabling them to respond to customers' inquiries while the customer is on the telephone. Finally, we believe that the knowledge and experience of our employees enhances the quality of support we provide.

Underwriting

Our underwriting department is responsible for a number of key decisions affecting the profitability of our business, including:

● pricing of our private passenger automobile, commercial automobile, homeowners, dwelling fire, personal umbrella, business owner, commercial umbrella and commercial package products;

● developing new products, coverages, forms and discounts, as well as expansion into new states;

● determining underwriting guidelines for all our products; and

● evaluating whether to accept transfers of a portion of an existing or potential new agent's portfolio from another insurer.

Pricing.  Subject to the applicable state insurance department’s review, we set rates for all of our products using our own loss experience, industry loss cost data, residual market deficits, catastrophe modeling and prices charged by our competitors. We have four pricing segments for most products, utilizing Safety Insurance for standard rates, Safety Indemnity for preferred rates and, Safety P&C for ultra preferred rates. We expect to begin offering a fourth homeowners rate level for risks that satisfy stricter underwriting guidelines through Safety Northeast in 2021.

Massachusetts Residual Automobile Insurance Markets. CAR establishes the rates for personal automobile policies assigned to carriers through the MAIP. In accordance with Massachusetts law, insurers may only charge MAIP policyholders the lower of the MAIP rate or the company's competitive voluntary market rate. CAR also sets rates for

7

commercial automobile policies, including taxi/limousine/car service policies, reinsured through the CAR residual market pool. All commercial automobile business and taxi/limousine/car service business that is not written in the voluntary market in Massachusetts is apportioned to one of these servicing carriers which handles that business on behalf of CAR. Every Massachusetts commercial automobile insurer must bear a portion of the losses of the total commercial reinsurance pool that is serviced by the approved servicing carriers. We are one of four servicing carriers in CAR’s Commercial Automobile Program and one of two servicing carriers in CAR’s Taxi/Limo Program.

Bulk Policy Transfers and New Voluntary Agents.  From time to time, we receive proposals from an existing voluntary agent to transfer a portfolio of the agent's business from another insurer to us. Our underwriters model the profitability of these portfolios before we accept these transfers. We generally require any new voluntary agent to commit to transfer a portfolio to us consisting of at least 300 policies.

Policy Processing.  Our underwriting department assists in processing policy applications, endorsements, renewals and cancellations. Our proprietary software, Safety Express, provides our agents with new business and endorsement entry, real-time policy issuance for personal lines, immediate printing of declarations pages in agents' offices, policy downloads to most major agency management systems and data imports from Boston Software's SinglePoint (Massachusetts) and Vertafore's PL Rater (Massachusetts, New Hampshire and Maine).

Rate Pursuit. We aggressively monitor all insurance transactions to make sure we receive the correct premium for the risk insured. We accomplish this by verifying pricing criteria. For automobile policies, we verify proper classification of drivers, the make, model, and age of insured vehicles, and the availability of discounts. We also verify that operators are properly listed and classified, assignment of operators to vehicles, and vehicle garaging. In our homeowners and dwelling fire lines, we use third party software to evaluate property characteristics and we conduct property inspections. We have a premium audit program in our business owner program, as well as other loss control reviews for additional commercial lines of business.

Product Management. The Product Management department is responsible for the overall review and updating of our products. The department maintains an annual schedule where each line of business is reviewed and benchmarked with our major competitors. Product offerings, discounts, rate levels and underwriting guidelines are reviewed and updates are performed as required. The department also is responsible for updating producer materials such as rate and rule manuals, and underwriting guidelines as well as promotional materials. In conjunction with the underwriting operations area, the department works with third party vendors that assist with risk information gathering and rate pursuit for in force policies. The department also provides product training and general marketplace education for the organization.

Legal and Regulatory Compliance. The Legal and Regulatory Compliance department provides legal and compliance support to all business units within the company. The department serves as the primary liaison with regulators, government, industry trade associations and residual market mechanisms. The department also provides legal support to all areas of the company, including general corporate matters and vendor contracting. The department monitors legal and regulatory changes affecting the enterprise and provides guidance on how to comply with those changes. The department additionally reviews business unit operations to identify and address compliance vulnerabilities.

Business Intelligence.  The Business Intelligence department uses Safety’s data assets to support decision-making in areas including underwriting, pricing, claims, reserving, reinsurance and assessing catastrophe risks.  Data analytics are used to analyze and estimate exposures, loss trends and other risks, and are leveraged to improve company business performance and customer satisfaction.

Technology

The focuses of our information technology (“IT”) efforts are:

● to support the strategic goals, objectives and business needs of the Company by aligning our IT annual goals with those of the business assuring that IT resources are being utilized efficiently;

8

● to constantly re-engineer internal processes to allow more efficient operations, resulting in lower operating costs;

● to continuously improve the customer experience making it easier for independent agents and policyholders to transact business with us;

● to enable agents to efficiently provide their clients with a high level of service; and

● to maintain and support a secure computing environment.

We believe that our technology initiatives have increased revenue and decreased costs while at the same time improving the customer experience of both our agents and policyholders. We are continuously investing in new technologies including areas such as robotic process automation and a new claims system which we began using for other than auto lines of business in 2020 and we plan to begin using for auto lines of business in 2021.

Innovation Lab. In 2018 we established an Innovation Lab. The purpose of the Innovation Lab is to foster a culture of innovative thinking, monitor the InsureTech landscape and provide Safety and our independent agents with the tools and processes necessary to continuously improve the customer experiences and remain competitive in both the current and future insurance marketplace. During 2020, the Innovation Lab explored Omnichannel for Customer Service offerings from both InsureTech and more established companies and we will look to implement a solution in 2021. The Innovation Lab also partnered with Safety’s Product Management department to explore home sensor devices to detect both water leakage and freeze. In late December 2020 an InsureTech was selected and Safety will be performing an internal Home Sensor Proof of Concept program in 2021 including freeze and water detection sensors along with a Smartphone Mobile app allowing participants to monitor the status of their sensors remotely. Finally during 2020, the Innovation Lab partnered with the Claims department to introduce electronic appraisals program using Smartphone technology that guides a consumer through a remote, touchless appraisal process that not only speeds the claims settlement process but proved very timely during the current social distancing environment.

Internal Applications

Our employees access our proprietary and vendor supplied applications through our corporate intranet. Our intranet applications streamline internal processes and improve overall operational efficiencies in areas including:

Claims.  Our claims workload management application allows our claims and subrogation adjusters to better manage the claims process. Subrogation refers to the process by which we are reimbursed by other insurers for claims costs we incur due to the fault of their insureds. The use of this application has reduced the time it takes for us to respond to and settle claims, which we believe helps reduce the total amount of our claims expense.

The automated adjuster assignment system categorizes our new claims by severity and assigns them to the appropriate adjuster responsible for investigation. Once assigned, the integrated workload management tools facilitate the work of promptly assigning appraisers, investigating liability, issuing checks and receiving subrogation receipts.

The RadicalGlass.com application allows our claims department to contain glass costs by increasing the windshield repair to replacement ratio.

We currently operate three VIP Claims Centers which use a network of rental car centers and auto body repair shops to provide a higher level of service to the clients of the independent insurance agents while reducing costs, such as rental expense, through reduced cycle times.

Billing.  Proprietary and vendor supplied billing systems, integrated with the systems of our print and lock-box vendors, expedite the processing and collection of premium receipts and finance charges from agents and policyholders. We believe the sophistication of our direct bill systems help us to limit our bad debt expense. Our bad debt expense as a percentage of direct written premiums was 0.4% in 2020 compared to 0.2% in 2019.

External Applications

Our agent technology offerings are centralized within our agency portal and feature PowerDesk and Safety Express. PowerDesk is a web-based application that allows for billing inquiry, agent payments on behalf of their policyholders, policy inquiry and claims inquiry. Safety Express provides agents with new business and endorsement entry, real-time policy issuance for personal lines, immediate printing of declarations pages in agents' offices, policy downloads to most major agency management systems and data imports from Boston Software's SinglePoint (Massachusetts) and Vertafore's PL Rater (Massachusetts, New Hampshire and Maine). In addition, we provide our agents with commission and claims download for all lines of business, Transformation Station and Transact Now Inquires, e-Claims online claims reporting, e-View daily transaction reports and e-Docs online electronic document file cabinet.

We also provide electronic billing (“eBill”), online bill pay (including credit and debit cards), online declarations pages, billing inquiry, claims inquiry, auto and homeowners claims first notice of loss, online auto insurance cards, and bill pay reminder alerts to our agents’ policyholders through our public website, SafetyInsurance.com. We have also updated our telephone system to provide a voice activated phone directory, automated billing inquiry and payments, and call center screen pop-up technology.

We additionally provide policyholders mobile technology through our Safety Mobile App for iPhone and Android devices. Safety Mobile provides consumers with access to their agent information, bill pay capabilities, the ability to report an automobile or homeowners claim and access to their insurance card, among other features.

Claims

On casualty claims we utilize stringent claims settlement procedures, which include guidelines that establish settlement ranges for soft tissue injuries, which constituted approximately 65% of our bodily injury claims in 2020. If we are unable to settle these claims within our pricing guidelines, we explore other cost-effective options including alternative dispute resolutions and/or litigation. We believe that these procedures result in providing our adjusting staff with a uniform approach to negotiation.

We believe an important component of handling claims efficiently is prompt investigation and settlement. We find that faster claims settlements often result in less expensive claims settlements. Our E-Claim reporting system is an online product that reduces the time it takes for agents to notify our adjusters about claims, thereby enabling us to contact third-party claimants and other witnesses quickly. Our insureds can report claims directly by phone, web, or mobile application. In addition, we utilize an after-hours reporting vendor to ensure that new claims can be reported 24 hours per day and 365 days per year.

We believe that early notification results in our adjusters conducting prompt investigations of claims and compiling more accurate information about those claims. Our claims workload management software also assists our adjusters in handling claims quickly.

We believe the structure of our claims department allows us to respond quickly to claimants. The department is organized into distinct claim units that contain loss costs on injury claims. Field adjusters are located geographically for prompt response to claims, with our litigation unit focused on managing loss costs and litigation expenses for serious injury claims.

Additionally, we utilize a special investigation unit to investigate potential fraud in connection with claims presented. In cases where adjusters suspect fraud in connection with a claim, we deploy this special unit to conduct investigations. We deny payment in cases in which we have succeeded in accumulating sufficient evidence of fraud.

Our auto physical damage claims units handle physical damage claims arising in our private passenger and commercial automobile lines. Process automation has streamlined our claims function and in combination with established policy and procedures newly reported claims are handling in a proactive manner to ensure that coverages are

10

verified, damages are appraised and claim payments are issued in a timely and efficient manner. This ensures the highest level of customer service to our insureds while reducing claim cycle times and mitigating claim handling expenses. We continue to vet and implement new methods of appraisal for vehicle damage, including vehicle photo only appraisals within the regulatory established guidelines. Once we receive this information, an automated system redirects the claim to the appropriate internal adjuster responsible for investigating the claim to determine liability. Upon determination of liability, the system automatically begins the process of seeking a subrogation recovery from another insurer, if liable. We believe this process results in a shorter time period from when the claimant first contacts the agent to when the claimant receives a claim payment, while enabling our agents to build credibility with their clients by responding to claims in a timely and efficient manner.

Our property claims division handles physical damage claims arising in our homeowners and other than auto insurance lines. Property Field Adjusters are located remotely across our service areas to handle larger more complex property losses. In 2020, we implemented a new claim handling software system that enables more efficient handling of the claim process from first notice of loss through settlement and potential subrogation. We also utilize house counsel on subrogation recoveries to reduce collection expenses and maximize damage recoveries.

Reserves

Significant periods of time can elapse between the occurrence of an insured loss, the reporting of the loss to the insurer and the insurer's payment of that loss. To recognize liabilities for unpaid losses, insurers establish reserves as balance sheet liabilities representing estimates of amounts needed to pay reported and unreported losses and the expenses associated with investigating and paying the losses, or loss adjustment expenses. Every quarter, we review and establish our reserves. Regulations promulgated by the Commissioner require us to annually obtain a certification from either a qualified actuary or an approved loss reserve specialist who may be one of our employees that our loss and loss adjustment expenses reserves are reasonable.

When a claim is reported, claims personnel establish a "case reserve" for the estimated amount of the ultimate payment. The amount of the reserve is primarily based upon an evaluation of the type of claim involved, the circumstances surrounding each claim and the policy provisions relating to the loss. The estimate reflects informed judgment of such personnel based on general insurance reserving practices and on the experience and knowledge of the claims person. During the loss adjustment period, these estimates are revised as deemed necessary by our claims department based on subsequent developments and periodic reviews of the cases.

In accordance with industry practice, we also maintain reserves for estimated losses incurred but not yet reported. Incurred but not yet reported reserves are determined in accordance with commonly accepted actuarial reserving techniques on the basis of our historical information and experience. We make adjustments to incurred but not yet reported reserves quarterly to take into account changes in the volume of business written, claims frequency and severity, our mix of business, claims processing and other items that can be expected to affect our liability for losses and loss adjustment expenses over time.

When reviewing reserves, we analyze historical data and estimate the impact of various loss development factors, such as our historical loss experience and that of the industry, legislative enactments, judicial decisions, legal developments in imposition of damages, and changes and trends in general economic conditions, including the effects of inflation. There is no precise method, however, for evaluating the impact of any specific factor on the adequacy of reserves, because the eventual development of reserves is affected by many factors. After taking into account all relevant factors, management believes that our provision for unpaid losses and loss adjustment expenses at December 31, 2020 is adequate to cover the ultimate cost of losses and claims incurred as of that date.

Management determines its loss and loss adjustment expense ("LAE") reserve estimates based upon the analysis of the Company's actuaries. Management has established a process for the Company's actuaries to follow in establishing reasonable reserves. The process consists of meeting with our claims department, establishing ultimate incurred losses

11

by using development models accepted by the actuarial community, and reviewing the analysis with management. The Company's estimate for loss and LAE reserves, net of the effect of ceded reinsurance, ranges from a low of $424,437 to a high of $478,251 as of December 31, 2020. The Company's net loss and LAE reserves, based on our actuaries' best estimate, were set at $461,270 as of December 31, 2020. The ultimate liability may be greater or less than reserves carried at the balance sheet date. Establishment of appropriate reserves is an inherently uncertain process, and there can be no certainty that currently established reserves will prove adequate in light of subsequent actual experience. To the extent that reserves are inadequate and are strengthened, the amount of such increase is treated as a charge to earnings in the period that the deficiency is recognized. To the extent that reserves are redundant and are released, the amount of the release is a credit to earnings in the period the redundancy is recognized. We do not discount any of our reserves.

The following table presents development information on changes in the reserves for losses and LAE of our Insurance Subsidiaries for each year in the three year period ended December 31, 2020, 2019 and 2018.

The following table represents the development of reserves, net of reinsurance, for calendar years 2010 through 2020. The top line of the table shows the reserves at the balance sheet date for each of the indicated years. This represents the estimated amounts of losses and loss adjustment expenses for claims arising in all years that were unpaid at the balance sheet date, including losses that had been incurred but not yet reported to us. The upper portion of the table shows the cumulative amounts paid as of the end of each successive year with respect to those claims. The lower portion of the table shows the re-estimated amount of the previously recorded reserves based on experience as of the end of each succeeding year, including cumulative payments made since the end of the respective year. The estimate changes as more information becomes known about the payments, frequency and severity of claims for individual years. Favorable loss development, shown as a cumulative redundancy in the table, exists when the original reserve estimate is greater than the re-estimated reserves at December 31, 2020.

In evaluating the information in the table, it should be noted that each amount entered incorporates the effects of all changes in amounts entered for prior periods. Thus, if the 2020 estimate for a previously incurred loss was $150 and the loss was reserved at $100 in 2016, the $50 deficiency (later estimate minus original estimate) would be included in the cumulative (redundancy) deficiency in each of the years 2016-2020 shown in the table. It should further be noted that the table does not present accident or policy year development data. In addition, conditions and trends that have affected the development of liability in the past may not necessarily recur in the future. Accordingly, it is not appropriate to extrapolate future redundancies or deficiencies from the table.

The table shows that we have substantially benefited in the current and prior years from releasing redundant reserves. In the years ended December 31, 2020, 2019, and 2018 we decreased loss reserves related to prior years by $54,844, $42,049 and $56,488, respectively. Reserves and development are discussed further in Item 7—Management's Discussion and Analysis of Financial Condition and Results of Operations, Executive Summary and Overview.

As a result of our focus on core business lines since our founding in 1979, we believe we have no specific exposure to asbestos or environmental pollution liabilities.

​
Reinsurance

Reinsurance involves an insurance company transferring (ceding) a portion of its exposure on insurance underwritten by it to another insurer (reinsurer). The reinsurer assumes a portion of the exposure in return for a share of the premium. Reinsurance does not legally discharge an insurance company from its primary liability for the full amount of the policies, but it does make the reinsurer liable to the company for the reinsured portion of any loss realized.

13

We reinsure with other insurance companies a portion of our potential liability under the policies we have underwritten, thereby protecting us against an unexpectedly large loss or a catastrophic occurrence that could produce large losses, primarily in our homeowners line of business. We are selective in choosing our reinsurers, seeking only those companies that we consider to be financially stable and adequately capitalized. In an effort to minimize exposure to the insolvency of a reinsurer, we continually evaluate and review the financial condition of our reinsurers. Most of our reinsurers have an A.M. Best rating of “A+” (Superior) or “A” (Excellent).

We maintain reinsurance coverage to help lessen the effect of losses from catastrophic events, maintaining coverage that during 2020 protected us in the event of a "137-year storm" (that is, a storm of a severity expected to occur once in a 137-year period). We use various software products to measure our exposure to catastrophe losses and the probable maximum loss to us for catastrophe losses such as hurricanes. The models include estimates for our share of the catastrophe losses generated in the residual market for property insurance by the Massachusetts Property Insurance Underwriting Association ("FAIR Plan"). In 2020, we purchased four layers of excess catastrophe reinsurance providing $615,000 of coverage for property losses in excess of $50,000 up to a maximum of $665,000.  Our reinsurers’ co-participation is 50.0% of $50,000 for the 1st layer, 80.0% of $50,000 for the 2nd layer, 80.0% of $250,000 for the 3rd layer, and 80.0% of $265,000 for the 4th layer.

For 2021, we have purchased the same four layers of excess catastrophe reinsurance providing $615,000 of coverage for property losses in excess of $50,000 up to a maximum of $665,000. Our reinsurers’ co-participation is 50.0% of $50,000 for the 1st layer, 80.0% of $50,000 for the 2nd layer, 80.0% of $250,000 for the 3rd layer and 80% of $265,000 for the 4th layer. As a result of the changes to the models, our catastrophe reinsurance in 2021 protects us in the event of a “135-year storm.”

We also have casualty excess of loss reinsurance for large casualty losses occurring in our automobile, homeowners, dwelling fire, business owner, and commercial package lines of business in excess of $2,000 up to a maximum of $10,000. We have property excess of loss reinsurance coverage for large property losses, with coverage in excess of $2,000 up to a maximum of $20,760, for our homeowners, business owners, and commercial package policies. In addition, we have liability excess of loss reinsurance for umbrella large losses in excess of $1,000 up to a maximum of $10,000. We also have various reinsurance agreements with Hartford Steam Boiler Inspection and Insurance Company, of which the primary contract is a quota share agreement under which we cede 100% of the premiums and losses for the equipment breakdown coverage under our business owner policies and commercial package policies.

Our reinsurance program excludes coverage for acts of terrorism. The Terrorism Risk Insurance Program Reauthorization Act of 2019 (“TRIPRA”) was signed into law on December 20, 2019 which extended TRIA through the year 2027. The intent of this legislation is to provide federal assistance to the insurance industry for the needs of commercial insurance policyholders with the potential exposure for losses due to acts of terrorism. The TRIEA provides reinsurance for certified acts of terrorism.

In addition to the above mentioned reinsurance programs and as described in more detail above under The Massachusetts Property and Casualty Insurance Market, we are a participant in CAR, a state-established body that, in part, runs the residual market reinsurance programs for commercial automobile insurance in Massachusetts under which premiums, expenses, losses and loss adjustment expenses on ceded business are shared by all insurers writing automobile insurance in Massachusetts. We also participate in the FAIR Plan in which premiums, expenses, losses and loss adjustment expenses on homeowners business that cannot be placed in the voluntary market are shared by all insurers writing homeowners insurance in Massachusetts. The FAIR Plan’s exposure to catastrophe losses increased and as a result, the FAIR Plan decided to buy reinsurance to reduce their exposure to catastrophe losses. On July 1, 2020, the FAIR Plan purchased $1,800,000 of catastrophe reinsurance for property losses with retention of $100,000.

At December 31, 2020, we also had $129,766 due from CAR comprising of loss and loss adjustment expense reserves, unearned premiums and reinsurance recoverables.

14

On March 10, 2005, our Board of Directors (the “Board”) adopted a resolution that prohibits Safety from purchasing finite reinsurance (reinsurance that transfers only a relatively finite or limited amount of risk to the reinsurer) without approval by the Board. To date, the Company has never purchased a finite reinsurance contract.

Competition

The property and casualty insurance business is highly competitive and many of our competitors have substantially greater financial and other resources than we do. We compete with both large national writers and smaller regional companies. Our competitors include companies which, like us, serve the independent agency market, as well as companies which sell insurance directly to customers. Direct writers may have certain competitive advantages over agency writers, including increased name recognition, loyalty of the customer base to the insurer rather than to an independent agency, and potentially, lower cost structures. A material reduction in the amount of business independent agents sell would adversely affect us. Further, we and others compete on the basis of the commissions and other cash and non-cash incentives provided to agents.

Although, historically, a number of national insurers that are much larger than we are have chosen not to compete in a material way in the Massachusetts private passenger automobile market, since 2008, several new companies have entered the market. These companies include some that would be able to sustain significant losses in order to acquire market share, as well as others which use distribution methods that compete with the independent agent channel. There can be no assurance that we will be able to compete effectively against these companies in the future.

Human Capital

At December 31, 2020, we employed 586 employees who all work in the New England region. Prior to COVID-19, approximately half of our employees particpated in a work from home program that helps contribute to a flexible work-life balance and allows the Company to minimize the real estate rented at our home office. In response to the pandemic, we quickly transitioned all other employees to a work from home environment and have the capacity for 100% of our workforce to work in a remote setting. Our employees are not covered by any collective bargaining agreement.

We create a workplace where all employees are treated with dignity and respect, and individual differences are valued, all with the goal of securing the trust and satisfaction of our employees. The Company is committed to a policy of inclusiveness and is committed to actively seeking out highly-qualified candidates with diverse gender, race, color, religion, ethnicity, age, marital status, handicap, sexual orientation, gender identity or expression, and backgrounds. 

We foster this culture through our robust learning and development program and our competitive compensation and health and benefit programs.

Our employees give both their time and their financial resources to charities of all types, and the company promotes corporate citizenship through charitable donations and company-sponsored volunteer activities. Safety is committed to making a positive impact on the communities where our employees live and work through our matching gift program, corporate giving and employee volunteerism. We help employees amplify their community impact by providing our employees with a 1:1 match on their donations to recognized charitable organizations. The Safety Insurance Charitable Foundation was established in 2005 and has provided financial support for a wide array of charities in areas such as community service, education, job training, homelessness, arts/culture, food banks, youth programs, healthcare, medical research and disaster relief.

The reputation of the Company depends on the conduct of its Board of Directors, officers, and employees.

Investments

Investment income is an important source of revenue for us and the return on our investment portfolio has a material effect on our net earnings. Our investment objective is to focus on maximizing total returns while investing conservatively. We maintain a high-quality investment portfolio consistent with our established investment policy. As of December 31, 2020, our portfolio of fixed maturity investments was comprised principally of investment grade corporate fixed maturity securities, U.S. government and agency securities, and asset-backed securities. The portion of our non-investment grade portfolio of fixed maturity investments is primarily comprised of variable rate secured and senior bank loans and high yield bonds.

According to our investment guidelines, no more than 2.0% of our portfolio may be invested in the securities of any one issuer (excluding U.S. government-backed securities). In addition, no more than 0.5% of our portfolio may be invested in securities of any one issuer rated "Baa," or the lowest investment grade assigned by Moody's. Of the less than 15.0% of our portfolio invested in senior bank loans and high yield bonds at December 31, 2020, no more than 5.0% may be invested in the securities of any one issuer, no more than 10.0% may be invested in any issuers total outstanding debt issue, and a maximum of 10.0% may be invested in securities unrated or rated "B-" or below by Moody's. We continually monitor the mix of taxable and tax-exempt securities in an attempt to maximize our total after-tax return. We utilize the services of third-party investment managers.

We believe that the incorporation of material, non-financial factors into investment selection and risk management has the potential to enhance long-term investment returns. We incorporate Environmental, Social & Governance (“ESG”) factors managed for us by third-party investment managers. We measure our exposure to ESG risks at both individual asset classes and total portfolio levels.
