2024 
ANNUAL 
REPORT 

Safety Insurance was founded in 1979 with a belief that we would 
succeed as a company if customers were given the best possible service. 
As we’ve grown and expanded our product line to include a full portfolio of 
property and casualty insurance products, staying committed to that belief 
has meant even more. At Safety, we do everything possible to make it easy 
for our agents and policyholders to do business with us.
Today, Safety is the third largest private passenger automobile carrier, 
the second largest commercial automobile carrier, and the third largest 
homeowners carrier in Massachusetts. We support our network of 
independent agents with state-of-the-art tools that make the ease and 
convenience of doing business with Safety second to none.
Together with our agents, Safety Insurance remains a premier provider 
of property and casualty insurance in Massachusetts, New Hampshire, and 
Maine. We’ll continue this tradition into the future.
We help you manage life’s storms
The key 
to our 
success: 
SERVICE.

Safety Insurance 2024 Annual Report  1
In 2024, Safety Insurance Group continued to achieve significant direct written 
premium growth, which increased 20.4% over the prior year, driving our top-line revenue above $1 billion for the 
first time in the company’s history. Our strong top-line growth was a result of an 8.5% increase in overall policy 
counts and a 10.9% increase in average premium per policy, blended across all lines of business.  
Along with the increased policy counts, premium rate actions are earning into our results and contributing to 
improvements in our loss ratios. For the year ended December 31, 2024, Safety Insurance posted a 101.1% 
combined ratio compared to 107.7% in the prior year. In addition, positive trends in other revenue lines contributed 
to stronger earnings per share and an increase in book value of 8.4%. While Safety achieved positive trends in all 
major revenue streams, ongoing inflationary impacts contributed to an elevated loss ratio specific to our Private 
Passenger Automobile book of business.  
The increases to direct written premiums and net written premiums were focused in our key areas of business, 
including policy count growth of 10.0%, 4.5% and 8.7% in Private Passenger Automobile, Commercial Automobile 
and Homeowners lines, respectively, compared to the same period in 2023. Average written premium per exposure 
increased 14.1%, 10.7% and 8.9% in Private Passenger Automobile, Commercial Automobile and Homeowners lines, 
respectively, compared to the same period in 2023.
The long-term commitment to strong underwriting results and enhanced investment returns, remains unchanged. 
As always, we focus on pricing our products appropriately for the risks we are insuring while generating the capital 
to grow our business. We continue to work with our agency partners toward our goal of maintaining underwriting 
discipline, while leveraging investments in our pricing and risk management areas to ensure rate adequacy.
Our investment objective focuses on maximizing total returns while investing conservatively. Net effective annual 
yield on our investment portfolio was 3.9% with net investment income of $55.7 million for the year ended 
December 31, 2024. We additionally generated $10.3 million on our partnership investments and $7.7 million in 
realized gains in 2024. The total income of $73.7 million in these three income sources represents a 16.6% increase 
as compared to the prior year. We believe that our current portfolio position and strong underlying operating cash 
flow provides sufficient liquidity to meet our needs.
Our long-standing strategy remains consistent as we look to maintain and develop strong independent agent 
relationships. In contrast to some of our competitors, 
Safety distributes its products exclusively through 
our extensive network of agents throughout 
Massachusetts, New Hampshire, and Maine. We 
support them with a full suite of insurance products 
and information technology services, which enables 
them to better serve their customers and more easily 
transact business with us.

Safety is proud of our history as an independent agency company and remains committed to the agency channel. Our 
ownership of Safety – Northeast Insurance Agency, allows us to leverage the benefits and offerings of the operation 
into our own internal Service Center. The agency also provides us the opportunity to develop new product and service 
offerings from our agency partner’s perspective. In 2024, we saw a 14.5% increase in commission income and pre-tax net 
income of $2.6 million when removing intercompany and depreciation expenses.
We continue to invest in technology enhancements for our core systems that are aimed at providing our independent 
agents and consumers with useful tools to enhance the user experience. During 2024, the Innovation Lab saw two 
of its successful proof of concepts make it into production in the claims area. The first, an electronic claims payment 
system was implemented to allow claim payments to be made 
electronically thus reducing cycle times and improving the customer 
experience and the second, a two-way texting system within the 
claims department to allow claims adjusters to correspond with 
customers via SMS text messaging. Other projects in 2024 included 
the introduction of a leak and freeze monitoring device program for 
our personal property customers. These devices provide real time 
alerts to customers if water or freezing temperatures are detected in 
the customers’ property. 
Our strategy of providing agents with value and unparalleled service 
has enabled Safety to establish strong relationships with agency partners and to capture a larger share of the total 
business written by each agent. We position ourselves as the preferred insurance carrier for those agents and are ranked 
first or second in over 70% of their agencies based on direct written premium. We have translated our competitive 
advantage and extensive knowledge of the market to become the second largest commercial automobile carrier, the third 
largest private passenger automobile carrier and the third largest homeowners carrier in Massachusetts. 
Our insurance subsidiaries ‘‘A’’ (Excellent) Financial Strength Rating was reaffirmed by A.M. Best on June 18, 2024. In 
reaffirming the rating, A.M. Best recognized our solid risk-adjusted capitalization, historically strong operating income, 
favorable loss reserve development, our market position as a leading property and casualty insurance writer in the New 
England region, and appropriate enterprise risk management. A.M. Best also noted our low investment leverage and 
disciplined underwriting approach as important strengths. 
We have a robust and formal Enterprise Risk Management Program that continuously evaluates risks in an ever-changing 
world. Through this program, our senior leadership team oversees the management and risk mitigation process and 
works with the Board of Directors to evolve our strategy and initiatives.
Direct written premium 
growth…increased 20.4% over 
the prior year, driving our 
top-line revenue above $1 
billion for the first time in the 
company’s history.

For the third consecutive year, we were named to the Ward’s 50 group of top performing property and casualty 
insurance companies. Ward Group analyzed the financial performance of nearly 3,000 property-casualty insurance 
companies based in the United States and identified the top performances based on objective data and subjective 
quality measures. Each company must pass primary safety and consistency tests and are measured and scored along 
five-year average returns on equity, assets, total revenue, growth in revenue, growth in surplus, and combined ratio.
Safety’s book value per share increased to $55.83 at December 31, 2024 from $54.37 at December 31, 2023 resulting 
from net income offset by dividends paid. Safety paid $3.60 per share in dividends to investors during the year ended 
December 31, 2024 and 2023, respectively. Our dividend yield ranks in the top three of our Performance Peer Group and 
remains a priority of the Board of Directors and management team.
We believe that Safety Insurance has a responsibility to both its 
stakeholders and the environment in which it operates. To that end, 
Safety Insurance is committed to developing conscious solutions for 
our employees, our community, our investors and our independent 
agency partners and policyholders. 
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. The Safety Insurance Charitable Foundation 
financially supports a wide array of charities in areas such as community service, veterans benefits, education, job training, 
homelessness, arts/culture, food banks, youth programs, healthcare, medical research and disaster relief.
With the support of an experienced, knowledgeable and dedicated senior management team, we continue to achieve 
financial success. The ongoing commitment of our employees, allows us to continually provide the best service possible 
to our independent agent partners and policyholders. This has resulted in a history of strong returns and enduring value 
for our stockholders. We appreciate your long-term participation as a stockholder of Safety Insurance Group.
Sincerely,

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"), Safety Property and Casualty Insurance Company ("Safety P&C"), and Safety Northeast 
Insurance Company (“Safety Northeast”) (together referred to as the "Insurance Subsidiaries"), we have established 
strong relationships with independent insurance agents, who numbered 828 in 1,079 locations throughout these three 
states during 2024.  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 9.7% and 12.9% share, respectively, of the Massachusetts private 
passenger and commercial automobile markets in 2024 according to statistics compiled by Commonwealth Automobile 
Reinsurers ("CAR").  We also are the third largest homeowners insurance carrier in Massachusetts with a 6.3% share of 
that market in 2023.  We were ranked the 55th largest automobile writer in the country according to S&P Global Market 
Intelligence, based on 2023 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 year ended December 31, 
2024, 2023, and 2022.

Our Competitive Strengths 
We Have Strong Relationships with Independent Agents.  In 2024, independent agents accounted for 
approximately 66.1% of the Massachusetts personal lines insurance market measured by direct written premiums as 
compared to approximately 39.0% nationwide, based on data made available by Independent Insurance Agents and 
Brokers of America, Inc. and CAR. 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 43 out of 44 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.   

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 provide our agents with state-of-the-art tools that make the ease and convenience 
of doing business with us second to none; and  

maintaining a high-quality investment portfolio.  
We Continue to Develop and Deploy Advanced Technology and Services for Our Business.  We have dedicated 
significant human and financial resources to the development and deployments of advanced information systems and 
technologies, customer and agent facing websites, mobile applications, and customer engagement tools including online 
chat and text.  Over the last several years we have modernized all of our core systems along with many of our surround 
systems and technology platforms in an effort to increase efficiencies within the organization and provide a better user 
experience for our employees, agents, and customers.  These modern systems and platforms position us to continue to 
take advantage of the latest in InsureTech offerings, Software as a Service (SaaS) products and cloud-based technologies 
to improve the customer experience, engage with customers on their terms, and assist with customer retention all while 
improving operational efficiencies and reducing operational costs.  We also continue to expand our usage of Robotics 
Process Automation throughout the organization to automate manual processes, streamline the software testing process 
and perform application performing testing to insure a robust technical environment.  
We Have an Experienced, Committed and Knowledgeable Management Team.  Our senior management team 
has an average of over 26 years of experience with Safety and a demonstrated ability to operate successfully within the 
property and casualty market.  

3 
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 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 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 (15.2% of 2024 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 (24.3% of 2024 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 (2.6% of 2024 direct written premiums).  We serve eligible small and medium sized 
commercial accounts with a program that covers apartments and residential condominiums; mercantile establishments, 
including 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 (0.9% of 2024 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 (1.1% of 2024 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.  
Commercial Umbrella (0.1% of 2024 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.  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 $10 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.  
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 

5 
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 828 and had 1,079 offices (some agencies 
have more than one office) and approximately 11,183 customer service representatives during 2024. 
Voluntary Agents.  In 2024, we obtained approximately 95.8% 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, 2024, we had agreements with 734 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 10.0% of our direct written premiums in 2024. 
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 for an additional five-year term effective 
January 1, 2022.  Historically, CAR ran a separate reinsurance pool for Taxi, Limousine and Car Service risks; however, 
beginning with the January 1, 2022 policy year, this pool was combined into the Commercial Automobile Program. 
Approximately $246,000 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.  
 We are assigned independent agents by CAR who can submit commercial business to us in the Commercial 
Automobile Program, and we classify those agents as Exclusive Representative Producers (“ERPs”).

In 2024, 61.3% of the private passenger automobile exposures we insure had an other than private passenger 
policy with us, compared to 64.5% and 65.2% in 2023 and 2022, respectively.  In addition, 82.2% of our homeowners’ 
policyholders had a matching automobile policy with us in 2024 compared to 83.0% in 2023 and 81.9% in 2022.  
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, paperless e-
Customer discounts, and also offering account discounts for policyholders that have more than one policy 
with us;  

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 and advertising campaign using a variety of radio, television, digital, social 
and print advertisements. 

7 
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.    
Further, we have a competitive agency incentive commission program under which we pay agents a percentage 
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 Agents Virtual Community 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 policies, billing and claims.  We are also committed to providing our agents with new information through our 
Marketing Toolkit and Resource Center articles on SafetyInsurance.com to keep their customers informed on how to best 
protect their auto, home and business.  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 and Insurance Operations
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, and commercial umbrella policies;  

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, Safety Northeast for ultra preferred rates and Safety P&C for high value homeowners 
rates. 
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 
commercial automobile policies, reinsured through the CAR residual market pool.  All commercial automobile business 
that is not written in the voluntary market in Massachusetts is apportioned to one of the servicing carriers that handles 
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. 
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 in written premium. 

8 
Policy Processing.  Our underwriting department assists in processing policy applications, endorsements, 
renewals and cancellations.  Our proprietary software applications, Safety Express and Safety Commercial Express, 
provide our agents with new business and endorsement entry, real-time policy issuance, 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) for personal lines.
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 
against our major competitors.   Product offerings, discounts, rate levels and underwriting guidelines are reviewed and 
updates are performed as required.  The department is also responsible for updating producer materials such as rate and 
rule manuals, underwriting guidelines, and promotional materials.  In conjunction with the underwriting operations area, 
the department works with third party vendors that assist with risk information, data, and rate pursuit for in-force 
policies.  The department also provides product training and general marketplace education for the organization. 
Legal.  The Legal department provides legal and compliance support to all business units within the Company.  
The department serves as the primary liaison with regulators, government, and industry trade associations. 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 unit within the Actuarial Services division is 
responsible for maintaining and improving the quality of Safety’s data, maintaining Safety’s enterprise data warehouse 
environment, and providing a suite of management reports and predictive analytical models to all departments and 
management levels at Safety. The Business Intelligence unit’s directive is to turn the daily transactional data in the 
warehouse into usable information to help Safety’s management team make more intelligent data-driven business 
decisions. 
Customer Engagement. The Customer Engagement department provides professional customer service to our 
agents and insureds by continuously identifying new ways to enhance the ease of doing business with us and by looking 
for new ways to personalize our services for each customer. 
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; 

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 

9 

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 for our employees, agents, and policyholders. In 2021, we introduced our Safety 
Commercial Express commercial auto quoting and policy issuance system in Massachusetts for new business. During 
2022, this system was updated to allow for agent processing of endorsements. In 2024, our Safety Commercial Express 
system was upgraded to the most current cloud enabled version of the system. We are continuously investing in new 
technologies, including areas such as robotic process automation, artificial intelligence, and automated testing to improve 
company efficiency.   
Cybersecurity. We continuously evolve our cybersecurity strategy to protect Safety's computer assets from a 
cybersecurity attack. Safety’s cybersecurity committee monitors the landscape for emerging threats, evaluates the latest 
preventative tools and methods, and recommends ways to increase enterprise security. An employee education program 
provides ongoing training to Safety's employees, including phishing tests and remediation training. Annual Tabletop 
exercises allow us to simulate cyber events to continuously improve our incidence response plans. 
Innovation Lab. Since 2018, we have had an Innovation Lab to foster a culture of innovative thinking, monitor 
the InsureTech landscape, and provide Safety, our independent agents, and policyholders with the tools and processes 
necessary to continuously improve the customer experience and remain competitive in both the current and future 
insurance marketplace.  During 2024, the Innovation Lab saw two of its successful proof of concepts make it into 
production in the claims area. In February, an electronic claims payment system was implemented to allow claim 
payments to be made electronically thus reducing cycle times and improving the customer experience. In the Fall of last 
year, we also implemented a two-way texting system within the claims department to allow claims adjusters to 
correspond with customers via SMS text messaging. In September of 2024, the Innovation Lab also partnered with the 
underwriting, insurance operations and marketing teams to introduce a leak and freeze monitoring device program for 
our personal property customers. These devices provide real time alerts to customers if water or freezing temperatures 
are detected in the customers’ property. During 2024, the Innovation Lab continued to perform research on Generative 
Artificial Intelligence (AI) and Large Language Models and produced working proof of concepts for internal use. In July 
of 2024, a “Generative AI In the Workplace Policy” was published governing the use of AI tools in the workplace. 
Internal Applications 
Our employees access our proprietary and vendor supplied applications through our secure corporate intranet. 
Our intranet applications streamline internal processes and improve overall operational efficiencies and customer 
experience in areas including: 
Claims. A vendor supplied claims system provides the claims department with a workload management 
application that 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 while also providing a better customer experience for the policyholder and 
claimant.   
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 payments, and receiving subrogation receipts. 
Billing. A 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. This 
billing system also allows for policyholder automatic payments (AutoPay) as well as electronic bill (eBill). We believe 
the sophistication of our direct bill system helps us to limit our bad debt expense.  Our bad debt expense as a percentage 
of direct written premiums was 0.3% and 0.2% in 2024 and 2023, respectively. 

10 
External Applications 
Our agent technology offerings are centralized within our agency portal and feature PowerDesk, Safety Express 
and Safety Commercial 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 and Safety Commercial Express 
provide 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, Vertafore's PL Rater, EZLynx and TurboRater. 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 eBill, online bill pay (including credit and debit cards), online AutoPay registration for both 
agents and customers, 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.   
Additionally, we provide policyholders with 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.  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 modern claims software provides our staff with efficient 
workplan management tools to assist our adjusters in handling claims quickly while providing high levels of customer 
service.  
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 adjusting resources are utilized for 
prompt response to large potential exposure claims and dedicated litigation staff focus on managing loss costs and 
litigation expense.  
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 handled in a proactive manner to ensure that coverages are 

11 
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 oversees 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.  Our modern claims software system and applications enables more efficient handling of the claim 
process and customer engagement 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 expense 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 professional.  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 (“IBNR”).  IBNR 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, 
2024 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 
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 $497,512 to a 

12 
high of $566,772 as of December 31, 2024.  The Company's net loss and LAE reserves, based on our actuaries' best 
estimate, were set at $540,877 as of December 31, 2024.  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, 2024, 2023 and 2022.

The following table represents the development of reserves, net of reinsurance, for calendar years 2014 through 
2024. 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, 2024. 

13 
Information with respect to the cumulative development of gross reserves (that is, without deduction for 
reinsurance ceded) also appears at the bottom portion of the table.

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 2024 estimate for a previously incurred loss was $150 and 
the loss was reserved at $100 in 2020, the $50 deficiency (later estimate minus original estimate) would be included in 
the cumulative (redundancy) deficiency in each of the years 2020-2023 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. 

14 
The table shows that we have substantially benefited in the current and prior years from releasing redundant 
reserves.  In the years ended December 31, 2024, 2023, and 2022 we decreased loss reserves related to prior years by 
$51,894, $47,381 and $57,279, 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.  
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 2024 protected us in the event of a "121-year storm" (that is, a storm of a severity expected to occur 
once in a 121-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. In 2024, we purchased three layers of excess 
catastrophe reinsurance providing $615,000 of coverage for property losses in excess of $75,000 up to a maximum of 
$690,000.  Our reinsurers’ co-participation is 80.0% of $75,000 for the 1st layer, 80.0% of $250,000 for the 2nd layer, 
and 80.0% of $290,000 for the 3rd layer.  
For 2025, we have purchased three layers of excess catastrophe reinsurance providing $675,000 of coverage for 
property losses in excess of $75,000 up to a maximum of $750,000.  Our reinsurers’ co-participation is 85.0% of 
$75,000 for the 1st layer, 85.0% of 250,000 for the 2nd layer and 85.0% of $350,000 for the 3rd layer.  
We also have casualty excess of loss reinsurance for large casualty losses occurring in our automobile, 
homeowners, dwelling fire, and business owner 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 $3,000 up to a 
maximum of $20,000, for our homeowners, and business owners.  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. 
Our reinsurance program excludes coverage for acts of terrorism. The Terrorism Risk Insurance Program 
Reauthorization Act of 2019 was signed into law on December 20, 2019 which extended the Terrorism Risk Insurance 
Act (“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.  TRIA 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 

15 
automobile insurance in Massachusetts.   
At December 31, 2024, we also had $168,538 due from CAR comprising of loss and loss adjustment expense 
reserves, unearned premiums and reinsurance recoverables. 
The Company participated in the Massachusetts Property Insurance Underwriting Association (“FAIR Plan”), 
in which premiums, expenses, losses and loss adjustment expenses on homeowners business that could not be placed in 
the voluntary market was shared by all insurers writing homeowners business in Massachusetts. On April 1, 2024, the 
Division approved a restructuring of the FAIR Plan (“FAIR Plan Restructuring”), transforming it from a partnership that 
shares profit and losses with member companies to a stand-alone, risk bearing entity, and distributing the accumulated 
members’ equity. 
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 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. 
We are the third largest writer of private passenger automobile insurance in Massachusetts with a market share 
of 9.7% in 2024. Our principal competitors within the Massachusetts private passenger automobile insurance market are 
MAPFRE SA, Government Employees Insurance Company, Progressive Casualty Insurance Company, and Plymouth 
Rock Assurance Corporation, which held 19.0%, 12.6%, 9.6% and 7.7% market shares based on premiums, respectively, 
in 2024 according to CAR. 
We are the second largest writer of commercial automobile insurance in Massachusetts with a market share of 
12.9% in 2024. Our principal competitors in the Massachusetts commercial automobile insurance market are MAPFRE 
SA, Arbella Mutual Insurance Company and Progressive Casualty Insurance Company, which held 13.1 %, 10.4% and 
9.4% market shares based on premium, respectively, according to CAR.  This includes our share of residual market 
business as one of four servicing carriers in CAR’s Commercial Automobile Program. 
We are the third largest writer of homeowners insurance business in Massachusetts, with a market share of 
6.3% in 2023.  Our principal competitors within the Massachusetts homeowners insurance market are MAPFRE SA, 
Liberty Mutual and The Andover Companies, which held 12.2%, 9.0% and 6.3% market shares, respectively, in 2023 
(according to S&P Global Market Intelligence).  

16 
Human Capital  
At December 31, 2024, we employed 551 employees who all work in the New England region.  The 
management team establishes hiring and compensation practices for our Company.  The Board is periodically updated on 
key employee engagement and employee relations measures.  In addition, the Board’s Compensation Committee is 
responsible for reviewing performance and approving compensation paid to senior leaders.  Our Human Resources team, 
led by our Chief Financial Officer, supports the Compensation Committee in the execution of its responsibilities.  In 
addition to the day-to-day support, they provide to our management team, the Human Resources team monitors the pulse 
of our employee population.   
As noted in our Environmental, Social and Governance (“ESG”) Report, located on our Company website, 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. The Company prioritizes an 
environment where employees are respected, inspired to perform at their best, and are recognized for their contributions.  
We persistently work to improve the employee experience in support of our continuing strategic objective to attract, 
retain and develop talent in the insurance industry. Our commitment to a robust talent pool starts at the top. The Board 
engages with the Compensation Committee annually to review executive level compensation, consider key pipeline 
talent and conduct succession planning. In addition, our leadership team conducts a comprehensive annual review 
process across our organization each year.  We have a history of promotion from within as approximately 19% of our 
organization has 25 years of experience at Safety.  
We offer competitive pay and benefits to our employees.  In addition to competitive salaries, all management 
level employees are included in our long-term incentive compensation program where they can receive a combination of 
time and performance-based awards.  The Company also engages in a number of additional practices to ensure pay 
fairness, including: 

Centralized compensation function ensuring consistent programs and practices across the enterprise; 

Enterprise-wide framework for evaluating and aligning roles and compensation levels based on job 
responsibilities, strategic importance of the role, and other relevant factors; 

Prohibition against asking external job applicants for current or historical compensation information; 

Individual compensation decisions consider each employee’s experience, proficiency, and performance; 

Multiple levels of review and approval required for all compensation decisions. 
We are committed to our extensive, long-standing policies and practices to ensure fair pay across the 
organization, while also staying attuned to external best practices and insights, and leveraging input from our pay 
consultants. 
We further foster our culture through our robust learning and development program and our competitive benefit 
programs. Our extensive benefits include a variety of items, not limited to the following: 

Medical and vision plan options; 

HSA & FSA options  

Dental options; 

Company paid life-insurance; 

401(k) plan with company matching contributions of up to 8%;

Flexible work schedules, including remote work arrangements; 

Tuition reimbursement that is not capped; 

Short and long-term disability; 

Family medical leave; 

Parental leave; 

Employee assistance program. 

17 
Our employees participate 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. Our employees are not covered by any 
collective bargaining agreement.   
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, officers, and employees.  Every employee 
who is associated with Safety must play a part in maintaining our corporate reputation for the highest ethical standards.  
Management considers our relationship with our employees to be strong. 
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, 2024, 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, 2024, 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 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.

(1) Residential mortgage-backed securities consists primarily of obligations of U.S. Government agencies including collateralized mortgage obligations 
and mortgage-backed securities guaranteed and/or insured by the following issuers: Government National Mortgage Association (GNMA), Federal 
Home Loan Mortgage Corporation (FHLMC), Federal National Mortgage Association (FNMA) and the Federal Home Loan Bank (FHLB). 
(2) Equity securities include common stock, preferred stock, mutual funds and interests in mutual funds held to fund the Company's executive deferred 
compensation plan. 
(3) Other invested assets are accounted for under the equity method which approximates fair value. 
The principal risks inherent in holding mortgage-backed securities and other pass-through securities are 
prepayment and extension risks, which affect the timing of when cash flows will be received.  When interest rates 
decline, mortgages underlying mortgage-backed securities tend to be prepaid more rapidly than anticipated, causing early 
repayments.  When interest rates rise, the underlying mortgages tend to be prepaid at a slower rate than anticipated, 
causing the principal repayments to be extended.  Although early prepayments may result in acceleration of income from 
recognition of any unamortized discount, the proceeds could be reinvested at a lower current yield, resulting in a net 
reduction of future investment income.  In addition, in the current market environment, such investments can also 
contain liquidity risks. 
The Company invests in bank loans which are primarily investments in senior secured floating rate loans that 
banks have made to corporations.  The loans are generally priced at an interest rate spread over the floating rate feature; 
this asset class provides protection against rising interest rates.  However, this asset class is subject to default risk since 
these investments are typically below investment grade. 
Equity risk is the risk that we will incur economic losses due to adverse changes in equity prices. Our exposure 
to changes in equity prices results from our holdings of common stock, preferred stock, mutual funds and interests in 
mutual funds held to fund the executive deferred compensation plan.  We continuously evaluate market conditions and 
we expect in the future to purchase additional equity securities. We principally manage equity price risk through industry 
and issuer diversification and asset allocation techniques.

Ratings are generally assigned upon the issuance of the securities and are subject to revision on the basis of 
ongoing evaluations. Ratings in the table are as of the date indicated. 
The Securities Valuation Office of the National Association of Insurance Commissioners (the "SVO") evaluates 
all public and private bonds purchased as investments by insurance companies. The SVO assigns one of six investment 
categories to each security it reviews. Category 1 is the highest quality rating and Category 6 is the lowest. Categories 1 
and 2 are the equivalent of investment grade debt as defined by rating agencies such as Standard & Poor's Ratings 
Services and Moody's, while Categories 3-6 are the equivalent of below investment grade securities. SVO ratings are 
reviewed at least annually. At December 31, 2024, 66.6% of our available for sale fixed maturity investments were rated 
Category 1 and 17.5% were rated Category 2, the two highest ratings assigned by the SVO.

(1) Actual maturities of asset-backed securities may differ from contractual maturities because borrowers may have the right to call or prepay 
obligations with or without call or prepayment penalties.  Prepayment rates are influenced by a number of factors that cannot be predicted with 
certainty, including: the relative sensitivity of the underlying mortgages or other collateral to changes in interest rates; a variety of economic, 
geographic and other factors; and the repayment priority of the securities in the overall securitization structures.

Ratings  
A.M. Best, which rates insurance companies based on factors of concern to policyholders, currently assigns the 
Company an "A (Excellent)" rating.  Our "A" rating was reaffirmed by A.M. Best on June 18, 2024.  Such rating is the 
third highest rating of 13 ratings that A.M. Best assigns to solvent insurance companies, which currently range from 
"A++ (Superior)" to "D (Poor)."  Publications of A.M. Best indicate that the "A" rating is assigned to those companies 
that in A.M. Best's opinion have an excellent ability to meet their ongoing obligations to policyholders over a long period 
of time. In evaluating a company's financial and operating performance, A.M. Best reviews the Company's profitability, 
leverage and liquidity, as well as its book of business, the adequacy and soundness of its reinsurance, the quality and 
estimated fair value of its assets, the adequacy of its loss reserves, the adequacy of its surplus, its capital structure, the 
experience and competence of its management and its market presence.  A.M. Best's ratings reflect its opinion of an 
insurance company's financial strength, operating performance and ability to meet its obligations to policyholders and 
are not evaluations directed to purchasers of an insurance company's securities. 
In assigning the Company’s rating, A.M. Best recognized its solid risk-adjusted capitalization, conservative 
operating strategy, and long-standing agency relationships. A.M. Best also noted among our positive attributes our 
favorable investment leverage, our disciplined underwriting approach, and our expertise in the closely managed 
Massachusetts automobile insurance market.  A.M. Best cited other factors that partially offset these positive attributes, 
including our concentration of business in the Massachusetts private passenger automobile market which exposes our 
business to regulatory actions. 
Supervision and Regulation  
Introduction.  Our principal operations are conducted through the Insurance Subsidiaries which are subject to 
comprehensive regulation by state insurance departments, primarily through our domestic regulator, the Division, of 
which the Commissioner is the senior official.  The Commissioner is appointed by the Governor.  We are subject to the 
authority of the Commissioner in many areas of our business under Massachusetts law, including: 

our licenses to transact insurance;  

the rates and policy forms we may use;  

our financial condition including the adequacy of our reserves and provisions for unearned premium;  

the solvency standards that we must maintain;  

the type and size of investments we may make;  

the prescribed or permitted statutory accounting practices we must use; and  

the nature of the transactions we may engage in with our affiliates.  
In addition, the Commissioner periodically conducts financial and market conduct examinations of all licensees 
domiciled in Massachusetts.  Our most recent financial condition examination was for the five-year period ending 
December 31, 2018.  The Division had no material findings as a result of this examination. The Division recently began 
their review of the five-year period ended December 31, 2023.  
We are also required to be licensed by the insurance department in each state in which we do business, as well 
as to comply with the various laws and regulations of those jurisdictions, including those governing our use of rates and 
policy forms in those states. 
Insurance Holding Company Regulation.  Our principal operating subsidiaries are insurance companies, and 
therefore we are subject to certain laws in Massachusetts regulating insurance holding company systems.  These laws 
require that we file a registration statement with the Commissioner that discloses the identity, financial condition, capital 
structure and ownership of each entity within our corporate structure and any transactions among the members of our 
holding company system. In some instances, we must provide prior notice to the Commissioner for material transactions 

21 
between our insurance company subsidiaries and other affiliates in our holding company system.  These holding 
company statutes also require, among other things, prior approval of the payment of extraordinary dividends or 
distributions and any acquisition of a domestic insurer and that we file an annual Enterprise Risk Management report 
with the Commissioner. 
Insurance Regulation Concerning Dividends.  We rely on dividends from the Insurance Subsidiaries for our 
cash requirements.  The insurance holding company law of Massachusetts requires notice to the Commissioner of any 
dividend to the shareholders of an insurance company.  The Insurance Subsidiaries may not make an "extraordinary 
dividend" until thirty days after the Commissioner has received notice of the intended dividend and has not objected in 
such time.  As historically administered by the Commissioner, this provision requires the prior approval by the 
Commissioner of an extraordinary dividend.  An extraordinary dividend is defined as any dividend or distribution that, 
together with other distributions made within the preceding twelve months exceeds the greater of 10.0% of the insurer's 
surplus as of the preceding December 31, or the insurer's net income for the twelve-month period ending the preceding 
December 31, in each case determined in accordance with statutory accounting practices. Under Massachusetts law, an 
insurer may pay cash dividends only from its unassigned funds, also known as its earned surplus, and the insurer's 
remaining surplus must be both reasonable in relation to its outstanding liabilities and adequate to its financial needs.  At 
December 31, 2024, the statutory surplus of Safety Insurance was $758,789 and its net income for 2024 was $43,387.  A 
maximum of $75,879 will be available during 2025 for such dividends without prior approval of the Commissioner. 
Acquisition of Control of a Massachusetts Domiciled Insurance Company.  Massachusetts law requires advance 
approval by the Commissioner of any change in control of an insurance company that is domiciled in Massachusetts.  
That law presumes that control exists where any person, directly or indirectly, owns, controls, holds the power to vote or 
holds proxies representing 10.0% or more of our outstanding voting stock.  Even persons who do not acquire beneficial 
ownership of more than 10.0% of the outstanding shares of our common stock may be deemed to have acquired control 
if the Commissioner determines that control exists in fact.  Any purchaser of shares of common stock representing 10.0% 
or more of the voting power of our capital stock will be presumed to have acquired control of the Insurance Subsidiaries 
unless, following application by that purchaser the Commissioner determines that the acquisition does not constitute a 
change of control or is otherwise not subject to regulatory review.  These requirements may deter, delay or prevent 
transactions affecting the control of or the ownership of our common stock, including transactions that could be 
advantageous to our stockholders. 
Protection Against Insurer Insolvency.  Massachusetts law requires that insurers licensed to do business in 
Massachusetts participate in the Massachusetts Insurers Insolvency Fund ("Insolvency Fund").  The Insolvency Fund 
must pay any claim up to $300 of a policyholder of an insolvent insurer if the claim existed prior to the declaration of 
insolvency or arose within sixty days after the declaration of insolvency.  Members of the Insolvency Fund are assessed 
the amount the Insolvency Fund deems necessary to pay its obligations and expenses in connection with handling 
covered claims.  Subject to certain exceptions, assessments are made in the proportion that each member's net written 
premiums for the prior calendar year for all property and casualty lines bore to the corresponding net written premiums 
for Insolvency Fund members for the same period.  As a matter of Massachusetts law, insurance rates and premiums 
include amounts to recoup any amounts paid by insurers for the costs of the Insolvency Fund.  By statute, no insurer in 
Massachusetts may be assessed in any year an amount greater than two percent of that insurer's direct written premium 
for the calendar year prior to the assessment.  We account for allocations from the Insolvency Fund as underwriting 
expenses.  CAR also assesses its members as a result of insurer insolvencies.  Because CAR is not able to recover an 
insolvent company's share of the net CAR losses from the Insolvency Fund, CAR must increase each of its member's 
shares of the deficit in order to compensate for the insolvent carrier's inability to pay its deficit assessment.  It is 
anticipated that there will be future assessments from time to time relating to various insolvencies. 
The Insurance Regulatory Information System.  The Insurance Regulatory Information System ("IRIS") was 
developed to help state insurance regulators identify companies that may require special financial attention. IRIS consists 
of a statistical phase and an analytical phase whereby financial examiners review annual statements and financial ratios.  
The statistical phase consists of 13 key financial ratios based on year-end data that are generated annually from the 
database of the National Association of Insurance Commissioners ("NAIC").  Each ratio has an established "usual range" 
of results.  These ratios assist state insurance departments in executing their statutory mandate to oversee the financial 
condition of insurance companies. 

22 
A ratio result falling outside the usual range of IRIS ratios is not considered a failing result; rather, unusual 
values are viewed 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 will become subject to regulatory scrutiny if it falls outside the usual ranges of four or more of the ratios.  In 
2024, 2023, and 2022 all our ratios for all our Insurance Subsidiaries were within the normal range. 
Risk-Based Capital Requirements.  The NAIC has adopted a formula and model law to implement risk-based 
capital requirements for most property and casualty insurance companies, which are designed to determine minimum 
capital requirements and to raise the level of protection that statutory surplus provides for policyholder obligations.  The 
risk-based capital formula for property and casualty insurance companies measures three major areas of risk facing 
property and casualty insurers: 

underwriting, which encompasses the risk of adverse loss developments and inadequate pricing;  

declines in asset values arising from market and/or credit risk; and  

off-balance sheet risk arising from adverse experience from non-controlled assets, guarantees for affiliates 
or other contingent liabilities and reserve and premium growth.  
Under Massachusetts law, insurers having less total adjusted capital than that required by the risk-based capital 
calculation will be subject to varying degrees of regulatory action, depending on the level of capital inadequacy. 
The risk-based capital law provides for four levels of regulatory action. The extent of regulatory intervention 
and action increases as the level of total adjusted capital to risk-based capital falls.  The first level, the company action 
level, as defined by the NAIC, requires an insurer to submit a plan of corrective actions to the Commissioner if total 
adjusted capital falls below 200% of the risk-based capital amount. The regulatory action level, as defined by the NAIC 
requires an insurer to submit a plan containing corrective actions and requires the Commissioner to perform an 
examination or other analysis and issue a corrective order if total adjusted capital falls below 150.0% of the risk-based 
capital amount. The authorized control level, as defined by the NAIC, authorizes the Commissioner to take whatever 
regulatory actions he or she considers necessary to protect the best interest of the policyholders and creditors of the 
insurer which may include the actions necessary to cause the insurer to be placed under regulatory control, 
i.e., rehabilitation or liquidation, if total adjusted capital falls below 100.0% of the risk-based capital amount. The fourth 
action level is the mandatory control level, as defined by the NAIC, which requires the Commissioner to place the 
insurer under regulatory control if total adjusted capital falls below 70.0% of the risk-based capital amount. 
The formulas have not been designed to differentiate among adequately capitalized companies that operate with 
higher levels of capital.  Therefore, it is inappropriate and ineffective to use the formulas to rate or to rank these 
companies.  At December 31, 2024, our Insurance Subsidiaries had total adjusted capital in excess of amounts requiring 
company or regulatory action at any prescribed risk-based capital action level. 
Own Risk Solvency Assessment.  On January 11, 2017, the Division adopted the National Association of 
Insurance Commissioners’ Own Risk Solvency Assessment (“ORSA”) Act requiring the Company to file its assessment 
on an annual basis.  ORSA is an internal process undertaken by an insurer or insurance group to assess the adequacy of 
its risk management and current and prospective solvency positions under normal and severe stress scenarios.  We have 
completed this filing for the 2024 period.

ITEM 1A.    RISK FACTORS 
An investment in our common stock involves a number of risks. Any of the risks described below could result in 
a significant or material adverse effect on our results of operations or financial condition, and a corresponding decline 
in the market price of our common stock.
We operate in a heavily regulated industry and are subject to regulations and laws in various jurisdictions:  
We are subject to comprehensive government regulation and our ability to earn profits may be restricted by these 
regulations. 
General Regulation.   We are subject to regulation by the state insurance department of each state in which we 
do business.  In each jurisdiction, we must comply with various laws and regulations, including those involving: 

approval or filing of premium rates and policy forms;  

limitation of the right to cancel or non-renew policies in some lines;  

requirements to participate in residual markets;  

licensing of insurers and agents; and 

regulation of the right to withdraw from markets or terminate involvement with agencies;  
We also are subject to enhanced regulation by our domestic regulator, the Division, from which we must obtain 
prior approval for certain corporate actions.  Among other things, we must comply with laws and regulations governing: 

transactions between an insurance company and any of its affiliates; 

the payment of dividends;  

the acquisition of an insurance company or of any company controlling an insurance company;  

solvency standards;  

minimum amounts of capital and surplus which must be maintained;  

limitations on types and amounts of investments;  

restrictions on the size of risks which may be insured by a single company;  

deposits of securities for the benefit of policyholders; and  

reporting with respect to financial condition.  
In addition, insurance department examiners from Massachusetts perform periodic financial and market conduct 
examinations of insurance companies. Such regulation is generally intended for the protection of policyholders rather 
than security holders. 
Massachusetts, New Hampshire and Maine require that all licensed property and casualty insurers bear a portion 
of the losses suffered by some insureds as a result of impaired or insolvent insurance companies by participating in each 
state’s insolvency fund.  Members of the state’s insolvency fund are assessed a proportionate share of the obligations and 
expenses of the fund in connection with an insolvent insurer. These assessments are made by the fund to cover the cost 
of paying eligible claims of policyholders of these insolvent insurers.  Similarly, assessments are made by each state’s 
commercial automobile insurance residual market mechanism to recover the shares of net losses that would have been 
assessed to the insolvent companies but for their insolvencies. In addition, Massachusetts has established an underwriting 
association in order to ensure that property insurance is available for owners of high risk property who are not able to 

27 
obtain insurance from private insurers. The losses of this underwriting association, the Massachusetts Property Insurance 
Underwriting Association, are shared by all insurers that write property and casualty insurance in Massachusetts. We are 
assessed from time to time to pay these losses. The effect of these assessments could reduce our profitability in any given 
period and limit our ability to grow our business. 
Because we are unable to predict with certainty changes in the political, economic or regulatory environments 
of the states in which we operate in the future, there can be no assurance that existing insurance-related laws and 
regulations will not become more restrictive in the future or that new restrictive laws will not be enacted and, therefore, it 
is not possible to predict the potential effects of these laws and regulations on us. 
There are anti-takeover provisions contained in our organizational documents and in laws of the State of Delaware 
and the Commonwealth of Massachusetts that could impede an attempt to replace or remove our management or 
prevent the sale of our company, which could diminish the value of our common stock. 
Our certificate of incorporation, bylaws and the laws of Delaware contain provisions that may delay, deter or 
prevent a takeover attempt that shareholders might consider in their best interests.  For example, our organizational 
documents provide for a classified board of directors with staggered terms and provide for the filling of vacancies on our 
board of directors by the vote of a majority of the directors then in office. These provisions will render the removal of the 
incumbent board of directors or management more difficult. In addition, these provisions may prevent shareholders from 
receiving the benefit of any premium over the market price of our common stock offered by a bidder in a potential 
takeover. Even in the absence of a takeover attempt, the existence of these provisions may adversely affect the prevailing 
market price of our common stock if they are viewed as discouraging takeover attempts in the future. 
The Massachusetts insurance law prohibits any person from acquiring control of us, and thus indirect control of 
the Insurance Subsidiaries, without the prior approval of the Commissioner. That law presumes that control exists where 
any person, directly or indirectly, owns, controls, holds the power to vote or holds proxies representing 10.0% or more of 
our outstanding voting stock. Even persons who do not acquire beneficial ownership of more than 10.0% of the 
outstanding shares of our common stock may be deemed to have acquired such control if the Commissioner determines 
that such control exists in fact. Therefore, any person seeking to acquire a controlling interest in us would face regulatory 
obstacles which could delay, deter or prevent an acquisition that shareholders might consider in their best interests. 
Section 203 of the General Corporation Law of Delaware, the jurisdiction in which the Company is organized, 
may affect the ability of an "interested stockholder" to engage in certain business combinations including mergers, 
consolidations or acquisitions of additional shares, for a period of three years following the time that the stockholder 
becomes an interested stockholder. An interested stockholder is defined to include persons owning directly or indirectly 
15.0% or more of the outstanding voting stock of the corporation. 
Our private passenger automobile business is concentrated in in New England: 
With a concentration of private passenger automobile insurance, our business may be adversely affected by 
conditions in this industry. 
Approximately 55.8% of our direct written premiums for the year ended December 31, 2024 were generated 
from private passenger automobile insurance policies. As a result of our focus on that line of business, negative 
developments in the economic, competitive or regulatory conditions affecting the private passenger automobile insurance 
industry could have a material adverse effect on our results of operations and financial condition. In addition, these 
developments would have a disproportionate effect on us, compared to insurers which conduct operations in multiple 
business lines. 

28 
Because we write insurance principally in Massachusetts, our business may be adversely affected by conditions in 
Massachusetts, including the impact of additional competitors. 
Almost all of our direct written premiums are currently generated in Massachusetts. Our revenues and 
profitability are therefore subject to prevailing regulatory, economic, demographic, competitive and other conditions in 
Massachusetts. Changes in any of these conditions could make it more costly or difficult for us to conduct our business. 
The Massachusetts market has seen an increased level of competition, particularly in the private passenger automobile 
insurance line, due to prior changes in regulatory conditions.  To date, we have not had a significant decrease in our 
private passenger automobile insurance business. However, further competition and adverse results could include loss of 
market share, decreased revenue, and/or increased costs. 
As writers of property insurance, our Insurance Subsidiaries are exposed to potential losses related to severe 
weather:   
We have exposure to claims related to severe weather conditions, which may result in an increase in claims frequency 
and severity. 
We are subject to claims arising out of severe weather conditions, such as rainstorms, snowstorms and ice 
storms, that may have a significant effect on our results of operations and financial condition. The incidence and severity 
of weather conditions are inherently unpredictable. There is generally an increase in claims frequency and severity under 
the private passenger automobile insurance we write when severe weather occurs because a higher incidence of vehicular 
accidents and other insured losses tend to occur as a result of severe weather conditions. In addition, we have exposure to 
an increase in claims frequency and severity under the homeowners and other property insurance we write because 
property damage may result from severe weather conditions. 
Because some of our insureds live near the Massachusetts coastline, we also have a potential exposure to losses 
from hurricanes and major coastal storms such as Nor'easters.  Although we purchase catastrophe reinsurance to limit 
our exposure to natural catastrophes, in the event of a major catastrophe resulting in property losses to us in excess of 
$690,000 our losses would exceed the limits of this reinsurance in addition to losses from our co-participation retention 
of a portion of the risk up to $690,000. 
Climate change and increasing climate change regulation may adversely impact our results of operations. 
There are concerns that the increase in weather-related catastrophes and other losses incurred by the industry in 
recent years may be indicative of changing weather patterns. This change in weather patterns could lead to higher overall 
losses and higher reinsurance costs. Changes in climate conditions may also cause our underlying modeling data to not 
adequately reflect frequency and severity, limiting our ability to effectively evaluate and manage risks of catastrophes 
and severe weather events. Among other impacts, this could result in not charging enough premiums or not obtaining 
timely state approvals for rate increases to cover the risks we insure.  Climate change could also have an impact on 
issuers of securities in which we invest, resulting in realized and unrealized losses in future periods which could have a 
material adverse impact on our results of operations and/or financial position. 
We are also subject to complex and changing laws and regulations relating to climate change which are difficult 
to predict and quantify and may have an adverse impact on our business. Changes in regulations relating to climate 
change or our own management decisions implemented as a result of assessing the impact of climate change on our 
business may result in an increase in the cost of doing business.  
We are subject to economic and underwriting market conditions: 
The impact of inflation and supply chain delays may increase loss severity.  

29 
Economic and market conditions outside of our control, such as inflation and supply chain issues, may 
adversely impact our underwriting profitability. Inflation in recent periods has significantly increased our loss costs 
across all lines of business, especially private passenger automobile. Inflation higher than the levels that the Company 
anticipates could continue to negatively impact our loss costs in future periods. 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.  
We operate in the highly competitive property and casualty insurance industry: 
If we are not able to attract and retain independent agents, it could adversely affect our business. 
We market our insurance solely through independent agents. We must compete with other insurance carriers for 
the business of independent agents. Some of our competitors offer a larger variety of products, lower prices for insurance 
coverage or higher commissions. While we believe that the commissions and services we provide to our agents are 
competitive with other insurers, changes in commissions, services or products offered by our competitors could make it 
harder for us to attract and retain independent agents to sell our insurance products. 
Established competitors with greater resources may make it difficult for us to market our products effectively and 
offer our products at a profit. 
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. Further, our competitors include other 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 directly and negatively affect our profitability and our ability to compete with insurers that 
do not rely solely on the independent agency market to sell their products. Further, our Company and others compete on 
the basis of the commissions and other cash and non-cash incentives provided to agents. Although a number of national 
insurers that are much larger than we are do not currently compete in a material way in the Massachusetts personal auto 
market, if one or more of these companies decided to aggressively enter the market it could reduce our share of the 
Massachusetts market and thereby have a material adverse effect on us. 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. Progressive Corporation, GEICO and Allstate, large insurers that market 
directly to policyholders rather than through agents, along with other carriers have entered the Massachusetts private 
passenger automobile insurance market.  
We may enter new markets and there can be no assurance that our diversification strategy will be effective. 
Although we intend to concentrate on our core businesses in Massachusetts, New Hampshire, and Maine, we 
also may seek to take advantage of prudent opportunities to expand our core businesses into other states where we 
believe the independent agent distribution channel is strong. As a result of a number of factors, including the difficulties 
of finding appropriate expansion opportunities and the challenges of operating in an unfamiliar market, we may not be 
successful in this diversification. Additionally, in order to carry out any such strategy we would need to obtain the 
appropriate licenses from the insurance regulatory authority of any such state. 

30 
The success of our business is subject to operational risks: 
We may not be able to successfully alleviate risk through reinsurance arrangements which could cause us to reduce 
our premiums written in certain lines or could result in losses. 
In order to reduce risk, to increase our underwriting capacity, and mitigate the volatility of losses on our 
financial condition and operations, we purchase reinsurance. The availability and the cost of reinsurance protection are 
subject to market conditions, which are outside of our control. As a result, we may not be able to successfully alleviate 
risk through these arrangements. For example, if reinsurance capacity for homeowner's risks were reduced as a result of 
terrorist attacks, climate change or other causes, we might seek to reduce the amount of homeowners business we write.  
As a result, the Company may not be able to successfully purchase reinsurance and transfer a portion of the Company’s 
risk through reinsurance arrangements. In addition, we are subject to credit risk with respect to our reinsurance because 
the ceding of risk to reinsurers does not relieve us of our liability to our policyholders. A significant reinsurer's 
insolvency or inability to make payments under the terms of a reinsurance treaty could have a material adverse effect on 
our results of operations or financial condition. 
As a holding company, Safety Insurance Group, Inc. is dependent on the results of operations of the Safety Insurance 
Company. 
Safety Insurance Group, Inc. is a company and a legal entity separate and distinct from Safety Insurance 
Company, our principal operating subsidiary. As a holding company without significant operations of its own, the 
principal sources of Safety Insurance Group, Inc.'s funds are dividends and other distributions from Safety Insurance 
Company. Our rights to participate in any distribution of assets of Safety Insurance Company are subject to prior claims 
of policyholders, creditors and preferred shareholders, if any, of Safety Insurance Company (except to the extent that our 
rights, if any, as a creditor are recognized). Consequently, our ability to pay debts, expenses and cash dividends to our 
shareholders may be limited. The ability of Safety Insurance Company to pay dividends is subject to limits under 
Massachusetts insurance law. Further, the ability of Safety Insurance Group, Inc. to pay dividends, and our subsidiaries' 
ability to incur indebtedness or to use the proceeds of equity offerings, will be subject to limits under our revolving credit 
facility. 
Our failure to maintain a commercially acceptable financial strength rating would significantly and negatively affect 
our ability to implement our business strategy successfully. 
A.M. Best has currently assigned Safety Insurance an "A (Excellent)" rating. An "A" rating is A.M. Best's third 
highest rating, out of 13 possible rating classifications for solvent companies. An "A" rating is assigned to insurers that 
in A.M. Best's opinion have an excellent ability to meet their ongoing obligations to policyholders. Moreover, an "A" 
rating is assigned to companies that have, on balance, excellent balance sheet strength, operating performance and 
business profile when compared to the standards established by A.M. Best. A.M. Best bases its ratings on factors that 
concern policyholders and not upon factors concerning investor protection. Such ratings are subject to change and are not 
recommendations to buy, sell, or hold securities. An important factor in an insurer's ability to compete effectively is 
its A.M. Best rating. Our A.M. Best rating is lower than those of some of our competitors. Any future decrease in our 
rating could affect our competitive position. 
Our losses and loss adjustment expenses may exceed our reserves, which could significantly affect our business. 
The reserves for losses and loss adjustment expenses that we have established are estimates of amounts needed 
to pay reported and unreported claims and related expenses based on facts and circumstances known to us as of the time 
we established the reserves. Reserves are based on historical claims information, industry statistics and other factors. The 
establishment of appropriate reserves is an inherently uncertain process. If our reserves are inadequate and are 
strengthened, we would have to treat the amount of such increase as a charge to our earnings in the period that the 
deficiency is recognized. As a result of these factors, there can be no assurance that our ultimate liability will not 
materially exceed our reserves and have a negative effect on our results of operations or financial condition. 

31 
Due to the inherent uncertainty of estimating reserves, it has been necessary, and may over time continue to be 
necessary, to revise estimated future liabilities as reflected in our reserves for claims and policy expenses. The historic 
development of reserves for losses and loss adjustment expenses may not necessarily reflect future trends in the 
development of these amounts. Accordingly, it is not appropriate to extrapolate redundancies or deficiencies based on 
historical information. 
If we lose key personnel, our ability to implement our business strategy could be delayed or hindered.  
The loss of key personnel could prevent us from fully implementing our business strategy and could 
significantly and negatively affect our financial condition or results of operations. As we continue to grow, we will need 
to recruit and retain additional qualified management personnel, and our ability to do so will depend upon a number of 
factors, such as our results of operations and prospects and the level of competition then prevailing in the market for 
qualified personnel. 
Acquisitions may not produce the anticipated benefits and may result in unintended consequences, which could have 
a material adverse impact on our financial condition or results of operations.
              We may not be able to successfully integrate acquired businesses or achieve the expected synergies as a result of 
such acquisitions.  The process of integrating an acquired business can be complex and costly and may create unforeseen 
operating difficulties that could result in the business performing differently than we expected, including through the loss 
of customers or in our failure to realize anticipated increased revenue growth or expense-related efficiencies. 
If our agency business does not perform well, we may be required to recognize an impairment of our goodwill. 
Goodwill represents the excess of the amounts we paid to acquire businesses over the fair value of their net 
assets at the date of acquisition.  We test goodwill at least annually for impairment.  Impairment testing is performed 
based upon estimates of the fair value of the “reporting unit” to which the goodwill relates.  The fair value of the 
reporting unit could decrease if new business, customer retention, profitability or other drivers of performance differ 
from expectations.  If it is determined that the goodwill has been impaired, we must write down the goodwill by the 
amount of the impairment, with a corresponding charge to net income (loss).  These write downs could have a material 
adverse effect on our results of operations or financial condition. 
Future sales of shares of our common stock by our existing shareholders in the public market, or the possibility or 
perception of such future sales, could adversely affect the market price of our stock. 
Investors currently known to be the beneficial owners of greater than 5.0% of our outstanding common stock 
hold approximately 45.3% of the common stock of Safety Insurance Group, Inc. on a fully diluted basis.  No prediction 
can be made as to the effect, if any, that future sales of shares by our existing shareholders, or the availability of shares 
for future sale, will have on the prevailing market price of our common stock from time to time.  Sales of substantial 
amounts of our common stock in the public market by our existing shareholders, or the possibility or perception that 
such sales could occur, could cause the prevailing market prices for our common stock to decrease. If such sales reduce 
the market price of our common stock, our ability to raise additional capital in the equity markets may be adversely 
affected. 
A proxy contest with an activist shareholder could cause us to incur significant costs, divert management’s attention 
and resources, and have an adverse effect on our business 
Activist shareholders may engage in proxy solicitations, advance shareholder proposals or director nominations 
or otherwise attempt to affect changes or acquire control over us.  Responding to these actions can be costly and time-
consuming and divert the attention of our Board and management from the management of our operations and the pursuit 
of our business strategies, particularly if such activist shareholders advocate for actions that are not supported by other 
shareholders, our Board or management.  In addition, perceived uncertainties as to our future direction may result in the 

32 
loss of potential business opportunities, damage to our reputation and may make it more difficult to attract and retain 
qualified directors, personnel and business partners. These actions could also cause our stock price to experience periods 
of volatility. 
We are subject to technology, cybersecurity and privacy risks: 
Our business depends on the uninterrupted operation of our systems and business functions, including our 
information technology, telecommunications and other business systems. Our business continuity and disaster 
recovery plans may not sufficiently address all contingencies. 
Our business is highly dependent upon our ability to execute, in an efficient and uninterrupted fashion, 
necessary business functions, such as processing new and renewal business, providing customer service, and processing 
and paying claims. A shut-down of or inability to access our facility, a power outage, or a failure of one or more of our 
information technology, telecommunications or other systems could significantly impair our ability to perform such 
functions on a timely basis. If sustained or repeated, such a business interruption, systems failure or service denial could 
result in a deterioration in the level of service we provide to our agents and policyholders. We have established a 
business continuity plan in an effort to ensure the continuation of core business operations in the event that normal 
business operations could not be performed due to a catastrophic event. While we continue to test and assess our 
business continuity plan to ensure it meets the needs of our core business operations and addresses multiple business 
interruption events, there is no assurance that core business operations could be performed upon the occurrence of such 
an event, which may result in a material adverse effect on our financial position or results of operations. 
We outsource certain business and administrative functions to third parties and may do so increasingly in the 
future.  If we fail to develop and implement our outsourcing strategies or our third-party providers fail to perform as 
anticipated, we may experience operational difficulties, increased costs and a loss of business that may have a material 
adverse effect on our results of operations or financial condition. 
Our business could be materially and adversely affected by a security breach or other attack involving our computer 
systems or the systems of one or more of our agents and vendors. 
Our highly automated and networked organization is subject to cyber-terrorism and a variety of other cyber-
security threats. These threats come in a variety of forms, such as viruses and malicious software. Such threats can be 
difficult to prevent or detect, and if experienced, could interrupt or damage our operations, harm our reputation or have a 
material effect on our operations. Our technology and telecommunications systems are highly integrated and connected 
with other networks. Cyber-attacks involving these systems could be carried out remotely and from multiple sources and 
could interrupt, damage or otherwise adversely affect the operations of these critical systems. Cyber-attacks could result 
in the modification or theft of data, the distribution of false information or the denial of service to users. The risks of 
cyber-attacks could be exacerbated by geopolitical tensions, including hostile actions taken by nation-states and terrorist 
organizations. We obtain, utilize and maintain data concerning individuals and organizations with which we have a 
business relationship. Threats to data security can emerge from a variety of sources and change in rapid fashion, resulting 
in the ongoing need to expend resources to secure our data in accordance with customer expectations and statutory and 
regulatory requirements.  
Our businesses must comply with regulations to control the privacy of customer, employee and third-party data, 
and state, federal and international regulations regarding data privacy, are becoming increasingly more onerous. A 
misuse or mishandling of confidential or proprietary information could result in legal liability, regulatory action and 
reputational harm.  We could be subject to liability if confidential customer information is misappropriated from our 
technology systems. Despite the implementation of security measures, these systems may be vulnerable to physical 
break-ins, computer viruses, programming errors, attacks by third parties or similar disruptive problems. Any well-
publicized compromise of security could deter people from entering into transactions that involve transmitting 
confidential information to our systems, which could have a material adverse effect on our business and reputation. We 
rely on services and products provided by many vendors. In the event that one or more of our vendors fails to protect 
personal information of our customers, claimants or employees, we may incur operational impairments, or could be 

33 
exposed to litigation, compliance costs or reputational damage.  We maintain cyber-liability insurance coverage to offset 
certain potential losses, subject to policy limits, such as liability to others, costs of related crisis management, data 
extortion, applicable forensics and certain regulatory defense costs, fines and penalties. 
While, to date, we are not aware of having experienced a material breach of our cyber security systems, 
administrative, internal accounting and technical controls as well as other preventive actions may be insufficient to 
prevent physical and electronic break-ins, denial of service, cyber-attacks, business email compromises, ransomware or 
other security breaches to our systems or those of third parties with whom we do business. 
We believe that we have established and implemented appropriate security measures to provide reasonable 
assurance that our information technology systems are secure and appropriate controls and procedures to enable us to 
identify and respond to unauthorized access to such systems.  While we have not experienced material cyber-incidents to 
date, the occurrence and effects of cyber-incidents may remain undetected for an extended period. We periodically 
engage third parties to evaluate and test the adequacy of our security measures, controls and procedures. Despite these 
security measures, controls and procedures, disruptions to and breaches of our information technology systems are 
possible.  
We invest in securities which are subject to market risk:  
Market fluctuations and changes in interest rates can have significant and negative effects on our investment 
portfolio. 
Our results of operations depend in part on the performance of our invested assets. As of December 31, 2024, 
based upon fair value measurement, 73.8% of our investment portfolio was invested in fixed maturity securities, 14.6% 
in equity securities, 10.3% in other invested assets, and 1.3% in short term investments. Certain risks are inherent in 
connection with debt securities including loss upon default and price volatility in reaction to changes in interest rates and 
general market factors. Changes in interest rates affect the carrying value of our fixed maturity investments and returns 
on our fixed maturity investments. A decline in interest rates reduces the returns available on new fixed maturity 
investments (including those purchases 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. 
We have a significant investment portfolio and adverse capital market conditions, including but not limited to 
volatility and credit spread changes, will impact the liquidity and value of our investments, potentially resulting in higher 
realized or unrealized losses. Values of our investments can also be impacted by reductions in price transparency and 
changes in investor confidence and preferences, potentially resulting in higher realized or unrealized losses. If the 
carrying value of our investments exceeds the fair value, and the decline in fair value is deemed to be other-than-
temporary, we will be required to write down the value of our investments, which could materially harm our results of 
operations or financial condition. 
ITEM 1B.    UNRESOLVED STAFF COMMENTS 
As of the date of this report, the Company had no unresolved comments from the Commission staff regarding 
its periodic or current reports under the Exchange Act. 
ITEM 1C.    CYBERSECURITY 
The Company has implemented a cybersecurity program that oversees, assesses, and manages its cybersecurity 
risks. As a component of the Company’s formal enterprise risk management program, whose goal is to support the 
business objectives and strategy, the cybersecurity program leverages multiple security measures to protect the integrity 
of the Company’s information assets. The program's strategy aligns to the National Institute of Standards and 

34 
Technology Cybersecurity Control Framework, where controls are implemented throughout our environment to achieve 
five categorical objectives of a cybersecurity program, including identification, protection, detection, response, and 
recovery.   
Our cybersecurity program is regularly assessed to ensure it meets the ever-changing cyber risk 
environment.  This is accomplished via monthly risk assessment meetings performed by our technical cybersecurity 
committee, periodic risk assessments and audits performed by internal audit, and cyber tests and assessments performed 
by contracted consultants.   
Our cybersecurity program includes several methods to protect against intrusion by a bad actor, including such 
techniques as reputational filtering, anti-virus scans, intrusion prevention, multi-factor authentication, and account 
isolation among others. We also use numerous approaches to detect ransomware and other cyber-attacks, including 
among others, dark web searches, email sandboxing, endpoint detection, and intrusion detection. The Company 
continuously monitors and enhances its program to respond to evolving cyber threats and changes in the regulatory 
environment. 
To ensure the effectiveness of the cybersecurity program, we have implemented various assurance methods 
including ongoing internal audit control reviews, external reviews by third-party consultants including penetration 
testing, and cyber incident response team exercises.  Ongoing monitoring of our systems and security metric reviews are 
in place to manage external threats.  Our cyber monitoring and supporting metrics include such areas as intrusion 
detection, phishing attempts, cyber training results, and patch management vulnerabilities.  Additionally, the Company 
collaborates with industry associations, government authorities, peers, and external advisors to monitor the threat 
environment to ensure no gaps exist in our security practices. 
A third-party risk management program is in place ensuring those risks associated with our use of vendors to 
support our business objectives and strategic initiatives are properly understood and mitigated.  Through management’s 
oversight, third-party assessments of vendor’s information security practices and protocols, including their readiness to 
protect against and respond to cybersecurity breaches are performed. Third-party service providers are categorized into 
tiers in consideration of the risk of a vendor’s activities. Vendor due diligence questionnaires are issued seeking to 
understand a service provider’s cyber and information security control environment, as well as their resiliency in the 
event of an intrusion to their systems.  Formalized vendor incident response procedures are in place that support the 
activities required should a cyber event occur. 
We continue to improve our ability to defend against, respond to, and recover from ransomware and other cyber 
events; enhance application cybersecurity capabilities, including defenses against fraud attacks; and to ensure security 
capabilities are built into new cloud-based platforms that we adopt. We are also required to maintain strong cyber 
defense protocols in the states where we are authorized or licensed to write business.  We monitor the status of new 
cybersecurity regulations, including notification requirements. 
To the best knowledge of management, no risks from cybersecurity threats have materially affected or are 
reasonably likely to materially affect the Company, including its business strategy, results of operations, or financial 
condition. 
Our Board is ultimately responsible for the oversight of risk management strategy, business plan and 
management of financial resources. As part of these responsibilities, the Board is apprised, annually and as needed, of 
developments in the external environment and business strategies that present increased cyber risk exposure to the 
Company. On a weekly basis, The Vice President of Management Information Services (“VP of MIS”) meets with the 
Chairman of the Board of Directors, President and Chief Executive Officer (“Chairman, President and CEO”), to discuss 
developments with the Company’s IT environment, including its cybersecurity program.  The Chairman, President and 
CEO would then inform the Board of those developments, as needed.  The Board has delegated oversight of 
cybersecurity risk management to the Audit Committee of the Board of Directors.    

35 
The Audit Committee meets on a quarterly basis.  A set agenda of risk matters includes detailed updates of the 
Company’s preparedness and significant cybersecurity activities. The topics covered by these updates have included 
discussions of policies and procedures to prevent, detect and respond to cybersecurity incidents, modifications to on-line 
platforms, and the use of cloud-based applications.  Lessons learned from cybersecurity incidents and the internal and 
external testing of our cyber defenses are provided quarterly.  The Board is also provided with an annual cybersecurity 
technology risk and control update.  
A management level risk committee exists and oversees the management of the Company’s highest-level risks, 
including cybersecurity. This committee consists of representatives from the Risk, Financial, Underwriting, Information 
Technology and Legal Departments. The Risk Committee, as supported by the Cybersecurity Committee, is responsible 
for keeping the audit committee apprised of the Company’s cybersecurity preparedness and cyber incidents. The 
Cybersecurity Committee oversees and ensures the Company’s cyber-related controls are sufficient to protect the 
Company’s information and proprietary assets, in accordance with the acceptable risk policies and risk tolerances. 
The VP of MIS has expertise assessing and managing cybersecurity risks, and is a member of both the Risk 
Committee and Cybersecurity Committee.  He has served in his current role since 2014 and has held several senior-level 
information technology roles in his 32-year tenure with the Company. In his various roles, he has been responsible for 
providing senior leadership in the areas of information security, IT governance risk & compliance, business continuity, 
and disaster recovery.  
ITEM 2.    PROPERTIES  
We conduct most of our operations in approximately 72 thousand square feet of leased space at 20 Custom 
House Street in downtown Boston, Massachusetts.  Our lease will expire on December 31, 2028.  This real estate space 
was remodeled in 2018 and included capital expenditures to update lighting as well as heating, ventilation and air 
condition systems with state of the art and environmentally focused technologies.   
ITEM 3.    LEGAL PROCEEDINGS  
Our Insurance Subsidiaries are parties to a number of lawsuits arising in the ordinary course of their insurance 
business.  We believe that the ultimate resolution of these lawsuits will not, individually or in the aggregate, have a 
material adverse effect on our financial condition. 
On October 19, 2021, the Supreme Judicial Court of Massachusetts (the “SJC”) unanimously ruled that property 
and casualty insurers must compensate third-party claimants under property damage coverage, part 4 of the standard 
Massachusetts automobile insurance policy, 2008 edition (standard policy), for the inherent diminished value (“IDV”) 
that occurs when their vehicles are damaged in a crash. This ruling overturned a previous decision by the Massachusetts 
Superior Court (the “Superior Court”), which found that a Massachusetts auto insurance policy did not provide property 
damage coverage for inherent diminished value damages for third-party claimants. The SJC placed the burden of proof 
on the individual claimant by explicitly specifying that the claimant must establish that the vehicle has suffered IDV 
damages and also the amount of IDV damages at issue. The SJC further ruled that an insurer’s previous denial of 
coverage for such damages could not serve as the basis for a claim of unfair business practices. On June 20, 2023, the 
Superior Court denied a motion brought by the plaintiffs seeking class certification. The plaintiffs had filed a motion to 
amend the complaint, seeking to address the concerns raised by the Superior Court in denying their motion for class 
certification, which Safety had opposed. The motion was denied, thus at this point, there will not be a renewed motion 
for class certification. Safety has not accrued for a specific loss contingency.

PART II. 
ITEM 5.    MARKET FOR THE REGISTRANT'S COMMON EQUITY, RELATED STOCKHOLDER MATTERS 
AND ISSUER PURCHASES OF EQUITY SECURITIES 
As of February 14, 2025, there were 7 holders of record of the Company's common stock, par value $0.01 per 
share, and we estimate another 19,346 held in "Street Name." 
The closing price of the Company's common stock on February 14, 2025 was $77.96 per share. The Company’s 
common stock trades on the NASDAQ stock exchange under the symbol SAFT. 
During 2024 and 2023, the Company’s Board declared four quarterly cash dividends to shareholders, which 
were paid and accrued in the amounts of $53,166 and $52,992, respectively.  On February 25, 2025, the Company's 
Board of Directors declared a quarterly cash dividend of $0.90 per share to shareholders of record on March 3, 2025 
payable on March 14, 2025. The Company plans to continue to declare and pay quarterly cash dividends in 2025, 
depending on the Company's financial position and the regularity of its cash flows. 
The Company relies on dividends from its Insurance Subsidiaries for a portion of its cash requirements. The 
payment by the Company of any cash dividends to the holders of common stock therefore depends on the receipt of 
dividend payments from its Insurance Subsidiaries. The payment of dividends by the Insurance Subsidiaries is subject to 
limitations imposed by Massachusetts law, as discussed in Item 1—Business, Supervision and Regulation, Insurance 
Regulation Concerning Dividends, and also in Item 7—Management's Discussion and Analysis of Financial Condition 
and Results of Operations, Liquidity and Capital Resources. 
The information called for by Item 201 (d) of Regulation S-K regarding securities authorized for issuance under 
equity compensation plans will be contained in the Company's Proxy Statement for its Annual Meeting of Shareholders, 
which the Company intends to file with the U.S. Securities and Exchange Commission within 120 days after 
December 31, 2024 (the Company's fiscal year end), and such information is incorporated herein by reference. 
For information regarding our share repurchase program, refer to Item 8—Financial Statements and 
Supplementary Data, Note 14, Share Repurchase Program, of this Form 10-K. 
COMMON STOCK PERFORMANCE GRAPH 
Set forth below is a line graph comparing the dollar change in the cumulative total shareholder return on the 
Company's Common Stock, for the period beginning on December 31, 2019 and ending on December 31, 2024 with the 
cumulative total return of the NASDAQ Stock Market Index and a peer group comprised of seven selected property & 
casualty insurance companies over the same period. The peer group consists of Donegal Group, Inc., Erie Indemnity 
Company, Horace Mann Educators Corporation, The Hanover Insurance Group, Inc., Mercury General Corp., Selective 
Insurance Group, Inc., and United Fire Group. Note that this peer group has changed from prior years due to acquisition 
activity. The graph shows the change in value of an initial one-hundred-dollar investment over the period indicated, 
assuming re-investment of all dividends.

ISSUER PURCHASES OF EQUITY SECURITIES  
On February 23, 2022, the Board of Directors approved an additional share repurchase of up to $50,000 of the 
Company’s outstanding common shares.  The Board of Directors has cumulatively authorized increases to the existing 
share repurchase program of up to $200,000 of its outstanding common shares.  Under the program, the Company may 
repurchase shares of its common stock for cash in public or private transactions, in the open market or otherwise.  The 
timing of such repurchases and actual number of shares repurchased will depend on a variety of factors including price, 
market conditions and applicable regulatory and corporate requirements.  The program does not require the Company to 
repurchase any specific number of shares and it may be modified, suspended or terminated at any time without prior 
notice.  No shares were repurchased during the three months ended December 31, 2024.

ITEM 6.    [RESERVED] 
ITEM 7.  MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF 
OPERATIONS 
The following discussion should be read in conjunction with our accompanying consolidated financial 
statements and notes thereto, which appear elsewhere in this document. In this discussion, all dollar amounts are 
presented in thousands, except share and per share data.
The following discussion contains forward-looking statements.  We intend statements which are not historical in 
nature to be, and are hereby identified as “forward-looking statements” to be covered by the safe harbor provisions of 
the Private Securities Litigation Reform Act of 1995. In addition, the Company’s senior management may make forward-
looking statements orally to analysts, investors, the media and others.  This safe harbor requires that we specify 
important factors that could cause actual results to differ materially from those contained in forward-looking statements 
made by or on behalf of us. We cannot promise that our expectations in such forward-looking statements will turn out to 
be correct. Our actual results could be materially different from and worse than our expectations. See “Forward-
Looking Statements” below for specific important factors that could cause actual results to differ materially from those 
contained in forward-looking statements.
Executive Summary and Overview
In this discussion, “Safety” refers to Safety Insurance Group, Inc. and “our Company,” “we,” “us” and “our” 
refer to Safety Insurance Group, Inc. and its consolidated subsidiaries. Our subsidiaries consist of Safety Insurance 
Company (“Safety Insurance”), Safety Indemnity Insurance Company (“Safety Indemnity”), Safety Property and 
Casualty Insurance Company (“Safety P&C”), Safety Northeast Insurance Company (“Safety Northeast”), Safety 
Northeast Insurance Agency, Inc. (“SNIA”), and Safety Management Corporation (“SMC”), which is SNIA’s holding 
company. 
We are a leading provider of private passenger automobile (55.8% of our direct written premiums in 2024), 
commercial automobile, (15.2% of 2024 direct written premiums), and homeowners (24.3% of 2024 direct written 
premiums) insurance.  In addition to these coverages, we offer a portfolio of other insurance products, including dwelling 
fire, umbrella and business owner policies (totaling 4.7% of 2024 direct written premiums).  Operating exclusively in 
Massachusetts, New Hampshire and Maine through our insurance company subsidiaries, Safety Insurance, Safety 
Indemnity, Safety P&C, and Safety Northeast (together referred to as the “Insurance Subsidiaries”), we have established 
strong relationships with independent insurance agents, who numbered 828 in 1,079 locations throughout these three 
states during 2024. We have used these relationships and our extensive knowledge of the market to become the third 
largest private passenger automobile carrier and the second largest commercial automobile carrier in Massachusetts, 
capturing an approximate 9.7% and 12.9% share, respectively, of the Massachusetts private passenger and commercial 
automobile markets in 2024, according to statistics compiled by the Commonwealth Automobile Reinsurers (“CAR”) 
based on automobile exposures.  We are the third largest homeowners insurance carrier in Massachusetts, with a market 
share of 6.3% in 2023. 
A.M. Best, which rates insurance companies based on factors of concern to policyholders, currently assigns 
Safety Insurance an “A (Excellent)” rating.  Our “A” rating was reaffirmed by A.M. Best on June 18, 2024. 
Our Insurance Subsidiaries began writing insurance in New Hampshire during 2008 and Maine in 2016.  In 
November 2020, we formed a fourth insurance subsidiary, Safety Northeast, which became licensed to write insurance 
products in Massachusetts.  The table below shows the amount of direct written premiums in each state during the years 
ended December 31, 2024, 2023, and 2022.

Recent Trends and Events
Direct and Net Written Premiums. For the quarter ended December 31, 2024, the Company achieved its ninth 
consecutive quarter of double-digit growth in direct and net written premiums. For the three months ended December 31, 
2024, direct written premium growth and net written premium growth were 18.7% and 12.9%, respectively. For the year 
ended December 31, 2024, direct written premium growth and net written premium growth were 20.4% and 18.2%, 
respectively. The increase in premium is driven by new business production, improved retention, and rate increases. For 
the year ended December 31, 2024, the Company achieved policy count growth across all lines of business, including 
10.0%, 4.5% and 8.7% in Private Passenger Automobile, Commercial Automobile and Homeowners lines, respectively, 
compared to the same period in 2023.  Additionally, for the year ended December 31, 2024, average written premium per 
policy increased 14.1%, 10.7% and 8.9% in Private Passenger Automobile, Commercial Automobile and Homeowners 
lines, respectively, compared to the same period in 2023. 
The following rate changes have been filed and approved by the insurance regulators of Massachusetts, New

Losses and Loss Adjustment Expenses. Losses and loss adjustment expenses incurred for the three months ended 
December 31, 2024 increased by $20,902, or 12.1%, to $193,007 from $172,105 for the comparable 2023 period. Losses 
and loss adjustment expenses incurred for the year ended December 31, 2024 increased by $74,335, or 11.6%, to 
$716,637 from $642,302 for the comparable 2023 period. The increase in losses for the three months ended and year 
ended December 31, 2024 is primarily driven by larger policy counts.  
Loss, expense, and combined ratios calculated under U.S. generally accepted accounting principles for the 
quarter ended December 31, 2024 were 71.7%, 30.2%, and 101.9%, respectively, compared to 76.1%, 30.4%, and 
106.5%, respectively, for the comparable 2023 period. Loss, expense, and combined ratios calculated under U.S. 
generally accepted accounting principles for the year ended December 31, 2024 were 70.9%, 30.2%, and 101.1%, 
respectively, compared to 77.0%, 30.7%, and 107.7%, respectively, for the comparable 2023 period. The 2024 decrease 

41 
in loss ratio is primarily due to the moderation of loss severity in Private Passenger Automobile, growth in earned 
premiums, and favorable prior year development. Additionally, the prior year loss ratio for the year ended December 31, 
2023 was impacted by two severe weather events, totaling $41,178. The 2024 decrease in the expense ratios in both 
periods is primarily driven by the increase in net earned premium.  
We define a “catastrophe” as an event that produces pre-tax losses before reinsurance in excess of $1,000 and 
involves multiple first-party policyholders, or an event that produces a number of claims in excess of a preset, per-event 
threshold of average claims in a specific area, occurring within a certain amount of time following the event.  
Catastrophes are caused by various natural events including high winds, winter storms, tornadoes, hailstorms, and 
hurricanes.  The nature and level of catastrophes in any period cannot be reliably predicted.   
Catastrophe losses incurred by the type of event are shown in the following table.

Statutory Accounting Principles 
Our results are reported in accordance with generally accepted accounting principles (“GAAP”), which differ 
from amounts reported in accordance with statutory accounting principles ("SAP") as prescribed by insurance regulatory 
authorities, which in general reflect a liquidating, rather than going concern concept of accounting.  Specifically, under 
GAAP:  

Policy acquisition costs such as commissions, premium taxes and other variable costs incurred which are 
directly related to the successful acquisition of a new or renewal insurance contract are capitalized and 
amortized on a pro rata basis over the period in which the related premiums are earned, rather than expensed as 
incurred, as required by SAP.  

Certain assets are included in the consolidated balance sheets whereas, under SAP, such assets are designated as 
"nonadmitted assets," and charged directly against statutory surplus. These assets consist primarily of premium 
receivables that are outstanding over ninety days, federal deferred tax assets in excess of statutory limitations, 
furniture, equipment, leasehold improvements and prepaid expenses.  

Amounts related to ceded reinsurance are shown gross of ceded unearned premiums and reinsurance 
recoverables, rather than netted against unearned premium reserves and loss and loss adjustment expense 
reserves, respectively, as required by SAP.  

Fixed maturities securities, which are classified as available-for-sale, are reported at current fair values, rather 
than at amortized cost, or the lower of amortized cost or market, depending on the specific type of security, as 
required by SAP.  

The differing treatment of income and expense items results in a corresponding difference in federal income tax 
expense. Changes in deferred income taxes are reflected as an item of income tax benefit or expense, rather than 
recorded directly to surplus as regards policyholders, as required by SAP.  Admittance testing may result in a 
charge to unassigned surplus for non-admitted portions of deferred tax assets.  Under GAAP reporting, a 
valuation allowance may be recorded against the deferred tax asset and reflected as an expense.  

42 
Insurance Ratios
The property and casualty insurance industry uses the combined ratio as a measure of underwriting 
profitability.  The combined ratio is the sum of the loss ratio (losses and loss adjustment expenses incurred as a percent 
of net earned premiums) plus the expense ratio (underwriting and other expenses as a percent of net earned premiums, 
calculated on a GAAP basis).  The combined ratio reflects only underwriting results and does not include income from 
investments or finance and other service income.  Underwriting profitability is subject to significant fluctuations due to 
competition, catastrophic events, weather, economic and social conditions, and other factors.   
Our GAAP insurance ratios are presented in the following table for the periods indicated.

Share-Based Compensation 
On March 24, 2022, the Company’s Board of Directors adopted the Amended and Restated Safety Insurance 
Group, Inc. 2018 Long-Term Incentive Plan (the “Amended 2018 Plan”), which was subsequently approved by our 
shareholders at the 2022 Annual Meeting of Shareholders. The Amended 2018 Plan increases the share pool limit by 
adding 350,000 common shares to the previously adopted Safety Insurance Group, Inc. 2018 Long-Term Incentive Plan.  
The Amended 2018 Plan enables the grant of stock awards, performance shares, cash-based performance units, other 
stock-based awards, stock options, stock appreciation rights, and stock unit awards, each of which may be granted 
separately or in tandem with other awards. Eligibility to participate includes officers, directors, employees and other 
individuals who provide bona fide services to the Company. The Amended 2018 Plan supersedes the Company’s 2002 
Management Omnibus Incentive Plan (“the 2002 Incentive Plan”).  
The Amended 2018 Plan establishes a pool of 700,000 shares of common stock available for issuance to our 
employees and other eligible participants.  The Board of Directors and the Compensation Committee intend to issue 
awards under the Amended 2018 Plan in the future.  
The maximum number of shares of common stock between both the 2018 Amended Plan and 2002 Incentive 
Plan with respect to which awards may be granted is 3,200,000. No further grants will be allowed under the 2002 
Incentive Plan. At December 31, 2024, there were 364,912 shares available for future grant. Grants outstanding under the 
plans as of December 31, 2024, were comprised of 136,754 restricted shares.

(1)  The fair value per share of the restricted stock grant is equal to the closing price of our common stock on the grant date. 
(2)  Board of Director members must maintain stock ownership equal to at least four times their annual cash retainer. This requirement must be met 
within five years of becoming a director.  
(3) The shares represent performance-based restricted shares award.  Vesting of these shares is dependent upon the attainment of pre-established 
performance objectives, and any difference between shares granted and shares earned at the end of the performance period will be reported at the 
conclusion of the performance period. 
(4)  The shares represent a true-up of previously awarded performance-based restricted share awards. The updated shares were calculated based on the 
attainment of pre-established performance objectives and granted under the Amended 2018 Plan. 
Reinsurance
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 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 reinsurance 
market has seen from the various software modelers, increases in the estimate of damage from hurricanes in the southern 
and northeast portions of the United States due to revised estimations of increased hurricane activity and increases in the 
estimation of demand surge in the periods following a significant event. We continue to manage and model our exposure 
and adjust our reinsurance programs as a result of the changes to the models. As of January 1, 2024, we purchased three 
layers of excess catastrophe reinsurance providing $615,000 of coverage for property losses in excess of $75,000 up to a 
maximum of $690,000.  Our reinsurers’ co-participation is 80.0% of $75,000 for the 1st layer, 80.0% of $250,000 for the 
2nd layer, and 80.0% of $290,000 for the 3rd layer.  As a result of the changes to the models, our catastrophe reinsurance 
in 2024 protects us in the event of a “121-year storm” (that is, a storm of a severity expected to occur once in a 121-year 
period).  Most of our reinsurers have an A.M. Best rating of “A+” (Superior) or “A” (Excellent). 
We are a participant in CAR, a state-established body that 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 commercial automobile insurance in Massachusetts.    
We also had $168,538 due from CAR comprising of loss and loss adjustment expense reserves, unearned 
premiums and reinsurance recoverables. 
Non-GAAP Measures 
Management has included certain non-generally accepted accounting principles (“non-GAAP”) financial 
measures in presenting the Company’s results. Management believes that these non-GAAP measures better explain the 

44 
Company’s results of operations and allow for a more complete understanding of the underlying trends in the Company’s 
business. These measures should not be viewed as a substitute for those determined in accordance with GAAP.  In 
addition, our definitions of these items may not be comparable to the definitions used by other companies. 
Non-GAAP operating income and non-GAAP operating income per diluted share consist of our GAAP net 
income adjusted by the net realized gains on investments, net impairment losses on investments, changes in net 
unrealized gains on equity securities, credit loss benefit (expense) and taxes related thereto. Net income and earnings per 
diluted share are the GAAP financial measures that are most directly comparable to non-GAAP operating income and 
non-GAAP operating income per diluted share, respectively. A reconciliation of the GAAP financial measures to these 
non-GAAP measures is included in the financial highlights below.

YEAR ENDED DECEMBER 31, 2024 COMPARED TO YEAR ENDED DECEMBER 31, 2023 
Direct Written Premiums.  Direct written premiums for the year ended December 31, 2024 increased by 
$201,833, or 20.4%, to $1,193,057 from $991,224 for the comparable 2023 period.  The increase in direct written 
premium is the result of new business production, improved retention, and rate increases. For the year ended December 
31, 2024, the Company achieved policy count growth across all lines of business, including 10.0%, 4.5% and 8.7% in 
Private Passenger Automobile, Commercial Automobile and Homeowners lines, respectively, compared to the same 
period in 2023.  Additionally, for the year ended December 31, 2024, average written premium per policy increased 
14.1%, 10.7% and 8.9% in Private Passenger Automobile, Commercial Automobile and Homeowners lines, respectively, 
compared to the same period in 2023. 
Net Written Premiums.  Net written premiums for the year ended December 31, 2024 increased by $168,110, or 
18.2%, to $1,093,405 from $925,295 for the comparable 2023 period.  The 2024 increase was primarily due to the 
factors that increased direct written premiums. 
Net Earned Premiums.  Net earned premiums for the year ended December 31, 2024 increased by $176,290, or 
21.1%, to $1,010,704 from $834,414 for the comparable 2023 period.  The 2024 increase was primarily due to the 
factors that increased direct written premiums.

Net Investment Income.  Net investment income for the year ended December 31, 2024 decreased by $657, or 
1.2%, to $55,720 from $56,377 for the comparable 2023 period. The decrease is a result of decreases due to the earned 
interest from our higher yield bonds and variable rate secured and senior bank loans. Net effective annual yield on the 
investment portfolio was 3.9% for the year ended December 31, 2024, compared to 4.0% for comparable 2023 period. 
Our duration was 3.5 years at December 31, 2024, compared to 3.6 years at December 31, 2023.   
Earnings from Partnership Investments.  Earnings from partnership investments were $10,271 for the year 
ended December 31, 2024 compared to $5,540 for the year ended December 31, 2023. The 2024 earnings reflect an 
increase in investment appreciation and distribution of investment returns compared to the prior year.  Timing and 
generation of these returns on capital can vary based on the results and transactions of the underlying partnerships.  
Net Realized Gains on Investments.  Net realized gains on investments were $7,720 for the year ended 
December 31, 2024 compared to $1,327 for the comparable 2023 period. The increase is driven by higher realized gains 
from the sale of equity securities compared to prior years.  
The gross unrealized gains and losses on investments in fixed maturity securities, including redeemable 
preferred stocks that have characteristics of fixed maturities, equity securities, including interests in mutual funds, and 
other invested assets were as follows:

The Company’s analysis of its fixed maturity portfolio at December 31, 2024 concluded that $1,198 of 
unrealized losses were due to credit factors and were recorded as an allowance for expected credit losses at December 
31, 2024, compared to $1,208 at December 31, 2023. The Company concluded that outside of the securities that were 
recognized as credit impaired, the unrealized losses recorded on the fixed maturity portfolio at December 31, 2024 and 
2023 resulted from fluctuations in market interest rates and other temporary market conditions as opposed to 
fundamental changes in the credit quality of the issuers of such securities.  Based upon the analysis performed, the 
Company’s decision to hold these securities, the Company’s current level of liquidity and our history of positive 
operating cash flows, management believes it is more likely than not that it will not be required to sell any of its 
securities before the anticipated recovery in the fair value to its amortized cost basis. 
Specific qualitative analysis was also performed for securities appearing on our “Watch List,” if any.  
Qualitative analysis considered such factors as the financial condition and the near term prospects of the issuer, whether 
the debtor is current on its contractually obligated interest and principal payments, changes to the rating of the security 
by a rating agency and the historical volatility of the fair value of the security. 
The majority of unrealized losses recorded on the investment portfolio at December 31, 2024 resulted from 
fluctuations in market interest rates and other temporary market conditions as opposed to fundamental changes in the 
credit quality of the issuers of such securities.  Given our current level of liquidity, the fact that we do not intend to sell 
these securities, and that it is more likely than not that we will not be required to sell these securities prior to recovery of 
the cost basis of these securities, these decreases in values are viewed as being temporary. 
For information regarding fair value measurements of our investment portfolio, refer to Item 8—Financial 
Statements and Supplementary Data, Note 16, Fair Value of Financial Instruments, of this Form 10-K. 
Commission Income: Commission income includes revenues from new and renewal commissions paid by 
insurance carriers, which we recognize when earned. Commission income was $7,942 and $6,932 for the years ended 
December 31, 2024 and 2023, respectively.  
Finance and Other Service Income.  Finance and other service income includes revenues from premium 
installment charges, which we recognize when earned, and other miscellaneous income and fees.  Finance and other 
service income increased by $4,306, or 22.2%, to $23,700 for the year ended December 31, 2024 from $19,394 for the 
comparable 2023 period. The increase is primarily driven by the increase in policy counts and changes to our fee 
assessment policies.   
Losses and Loss Adjustment Expenses.  Losses and loss adjustment expenses incurred for the year ended 
December 31, 2024 increased by $74,335, or 11.6%, to $716,637 from $642,302 for the comparable 2023 period.   
Our GAAP loss ratio for the years ended December 31, 2024 and 2023 were 70.9% and 77.0%, respectively. 
Our GAAP loss ratio excluding loss adjustment expenses was 62.6% and 67.9% for the years ended December 31, 2024 
and 2023, respectively. Total prior year favorable development included in the pre-tax results for the year ended 
December 31, 2024 was $51,894, compared to $47,381 for the comparable 2023 period.   

48 
Underwriting, Operating and Related Expenses.  Underwriting, operating and related expenses for the year 
ended December 31, 2024 increased by $48,742, or 19.0%, to $305,322 from $256,580 for the comparable 2023 period. 
The increase is driven by an increase in base commissions resulting from the increase in written premiums, offset by a 
decrease in contingent commission expense. Our GAAP expense ratio for the year ended December 31, 2024 decreased 
to 30.2% from 30.7% for the comparable 2023 period.   
Other Expense: Other expense includes the operating and related expenses associated with SNIA. 
Interest Expense.  Interest expense was $509 and $818 for the years ended December 31, 2024 and 2023, 
respectively. Interest expense primarily relates to the borrowing from the FHLB as noted within Item 8 – Financial 
Statements and Supplementary Data, Note 10, Debt, of this Form 10-K. The credit facility commitment fee included in 
interest expense was $60 and $75 for the years ended December 31, 2024 and 2023, respectively. 
Income Tax Expense.  Our effective tax rates were 21.3% and 22.7% for the years ended December 31, 2024 
and 2023, respectively. The effective rates for the year ended December 31, 2024 and 2023 were higher than the 
statutory rate primary due to the impact of stock-based and executive compensation.  
The comparison of results for the year ended December 31, 2023 compared to the year ended December 31, 
2022 can be found in the Company’s 2023 Annual Report on Form 10-K filed with the SEC on February 28, 2024. 
Liquidity and Capital Resources
As a holding company, Safety’s assets consist primarily of the stock of our direct and indirect subsidiaries.  
Our principal source of funds to meet our obligations and pay dividends to shareholders, therefore, is dividends and other 
permitted payments from our subsidiaries, principally Safety Insurance.  Safety is the borrower under our credit facility. 
Safety Insurance’s sources of funds primarily include premiums received, investment income and proceeds 
from sales and redemptions of investments.  Safety Insurance’s principal uses of cash are the payment of claims, 
operating expenses and taxes, the purchase of investments and payment of dividends to Safety. 
Net cash provided by operating activities was $128,688, $52,114, and $44,326 during the years ended 
December 31, 2024, 2023, and 2022, respectively.  Our operations typically generate positive cash flows from operations 
as most premiums are received in advance of the time when claim and benefit payments are required. These positive 
operating cash flows are expected to continue to meet our liquidity requirements. 
Net cash used for investing activities was $54,541 during the year ended December 31, 2024 compared to net 
cash provided by investing activities of $24,269 for December 31, 2023, and net cash used for investing activities of 
$19,988 for the year ended December 31, 2022. This fluctuation was driven by purchases exceeding proceeds from sales, 
paydowns, calls and maturities of fixed maturity and equity securities in 2024.   
Net cash used for financing activities was $53,325, $63,531, and $62,641 during the years ended December 31, 
2024, 2023 and 2022, respectively. Net cash used for financing activities during the year ended December 31, 2024 
consisted of dividend payments to shareholders.  
The Insurance Subsidiaries maintain a high degree of liquidity within their respective investment portfolios in 
fixed maturity and short-term investments.  We do not anticipate the need to sell these securities to meet the Insurance 
Subsidiaries cash requirements.  We expect the Insurance Subsidiaries to generate sufficient operating cash to meet all 
short-term and long-term cash requirements. However, there can be no assurance that unforeseen business needs or other 
items will not occur causing us to have to sell securities before their values fully recover; thereby causing us to recognize 
additional impairment charges in that time period.

For information regarding Recent Accounting Pronouncements, please refer to Item 8—Financial Statements 
and Supplementary Data, Note 2, Summary of Significant Accounting Policies, of this Form 10-K. 
Regulatory Matters
Our insurance company’s 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 the Commissioner.  The Massachusetts 
statute limits the dividends an insurer may pay in any twelve-month period, without the prior permission of the 
Commissioner, to the greater of (i) 10% of the insurer’s surplus as of the preceding December 31 or (ii) the insurer’s net 
income for the twelve-month period ending the preceding December 31, in each case determined in accordance with 
statutory accounting practices. Our Insurance Subsidiaries may not declare an “extraordinary dividend” (defined as any 
dividend or distribution that, together with other distributions made within the preceding twelve months, exceeds the 
limits established by Massachusetts statute) until thirty days after the Commissioner has received notice of the intended 
dividend and has not objected.  As historically administered by the Commissioner, this provision requires the 
Commissioner’s prior approval of an extraordinary dividend. Under Massachusetts law, an insurer may pay cash 
dividends only from its unassigned funds, also known as earned surplus, and the insurer’s remaining surplus must be 
both reasonable in relation to its outstanding liabilities and adequate to its financial needs.  At year-end 2024, the 
statutory surplus of Safety Insurance was $758,789, and its net income for 2024 was $43,387.  As a result, a maximum 
of $75,879 is available in 2024 for such dividends without prior approval of the Commissioner. As a result of this 
Massachusetts statute, the Insurance Subsidiaries had restricted net assets in the amount of $682,910 at December 31, 
2024. During the twelve months ended December 31, 2024, Safety Insurance recorded dividends to Safety of $51,123. 
The maximum dividend permitted by law is not indicative of an insurer’s actual ability to pay dividends, which 
may be constrained by business and regulatory considerations, such as the impact of dividends on surplus, which could 
affect an insurer’s ratings or competitive position, the amount of premiums that can be written and the ability to pay 
future dividends. 
Since the initial public offering of its common stock in November 2002, the Company has paid regular quarterly 
dividends to shareholders of its common stock. Quarterly dividends paid during 2024 and 2023 were as follows:

On February 14, 2025, our Board approved and declared a quarterly cash dividend on our common stock of 
$0.90 per share to be paid on March 14, 2025 to shareholders of record on March 3, 2025. We plan to continue to declare 
and pay quarterly cash dividends in 2025, depending on our financial position and the regularity of our cash flows. 

50 
On February 23, 2022, the Board approved a share repurchase program of up to $50,000 of the Company’s 
outstanding common shares.  The Board of Directors had cumulatively authorized increases to the existing share 
repurchase program of up to $200,000 of its outstanding common shares.  Under the program, the Company may 
repurchase shares of its common stock for cash in public or private transactions, in the open market or otherwise.  The 
timing of such repurchases and actual number of shares repurchased will depend on a variety of factors including price, 
market conditions and applicable regulatory and corporate requirements.  The program does not require the Company to 
repurchase any specific number of shares and may be modified, suspended or terminated at any time without prior 
notice.   
No share purchases were made by the Company during the year ended December 31, 2024. During the year 
ended December 31, 2023, the Company purchased 74,213 shares at a cost of $5,240. As of December 31, 2024 and 
2023, the Company had purchased 3,215,690 shares on the open market at a cost of $155,240.   
Management believes that the current level of cash flow from operations provides us with sufficient liquidity to 
meet our operating needs over the next 12 months.  We expect to be able to continue to meet our operating needs after 
the next 12 months from internally generated funds.  Since our ability to meet our obligations in the long term (beyond 
such twelve-month period) is dependent upon such factors as market changes, insurance regulatory changes and 
economic conditions, no assurance can be given that the available net cash flow will be sufficient to meet our operating 
needs.  We expect that we would need to borrow or issue capital stock if we needed additional funds, for example, to pay 
for an acquisition or a significant expansion of our operations.  There can be no assurance that sufficient funds for any of 
the foregoing purposes would be available to us at such time. 
Contractual Obligations 
We have obligations to make future payments under contracts and credit-related financial instruments and 
commitments.   
As of December 31, 2024, the Company had loss and LAE reserves of $671,669, unpaid reinsurance 
recoverables of $130,792 and net loss and LAE reserves of $540,877.  Our loss and LAE reserves are estimates as 
described in more detail under Critical Accounting Policies and Estimates.  The specific amounts and timing of 
obligations related to case reserves, IBNR reserves and related LAE reserves are not set contractually, and the amounts 
and timing of these obligations are unknown.  While management believes that historical performance of loss payment 
patterns is a reasonable source for projecting future claims payments, there is inherent uncertainty in this estimated 
projected settlement of loss and LAE reserves, and as a result these estimates will differ, perhaps significantly, from 
actual future payments.  
As part of the Company’s investment activity, we have committed $170,000 to investments in limited 
partnerships.  The Company has contributed $144,682 to these commitments as of December 31, 2024.  As of 
December 31, 2024, the remaining committed capital that could be called is $34,033, which includes potential recallable 
capital distributions. 
Critical Accounting Policies and Estimates
Loss and Loss Adjustment Expense Reserves
Significant periods of time can elapse between the occurrence of an insured loss, the reporting to us of that loss 
and our final payment of that loss.  To recognize liabilities for unpaid losses, we establish reserves as balance sheet 
liabilities.  Our reserves represent estimates of amounts needed to pay reported and estimated losses incurred but not yet 
reported (“IBNR”) and the expenses of investigating and paying those losses, or loss adjustment expenses.  Every 
quarter, we review our previously established reserves and adjust them, if necessary. 
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 the informed 

51 
judgment of such personnel based on general insurance reserving practices and on the experience and knowledge of the 
claims professional.  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.  When a claim is closed with or 
without a payment, the difference between the case reserve and the settlement amount creates a reserve deficiency if the 
payment exceeds the case reserve or a reserve redundancy if the payment is less than the case reserve. 
In accordance with industry practice, we also maintain reserves for IBNR.  IBNR reserves are determined in 
accordance with commonly accepted actuarial reserving techniques on the basis of our historical information and 
experience.  We review and make adjustments to incurred but not yet reported reserves quarterly.  In addition, IBNR 
reserves can also be expressed as the total loss reserves required less the case reserves on reported claims. 
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, trends in claims frequency and severity, our mix of 
business, our claims processing procedures, legislative enactments, judicial decisions, legal developments in imposition 
of damages, and changes and trends in general economic conditions, including the effects of inflation.  A change in any 
of these factors from the assumption implicit in our estimate can cause our actual loss experience to be better or worse 
than our reserves, and the difference can be material.  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. 
In estimating all our loss reserves, we follow the guidance prescribed by ASC 944, Financial Services – 
Insurance. 
Management determines our loss and loss adjustment expense reserves estimate based upon the analysis of our 
actuaries.  A reasonable estimate is derived by selecting a point estimate within a range of indications as calculated by 
our actuaries using generally accepted actuarial techniques. The key assumption in most actuarial analysis is that past 
patterns of frequency and severity will repeat in the future, unless a significant change in the factors described above 
takes place.  Our key factors and resulting assumptions are the ultimate frequency and severity of claims, based upon the 
most recent ten years of claims reported to the Company, and the data CAR reports to us to calculate our share of the 
residual market, as of the date of the applicable balance sheet.  For each accident year and each coverage within a line of 
business our actuaries calculate the ultimate losses incurred.  Our total reserves are the difference between the ultimate 
losses incurred and the cumulative loss and loss adjustment payments made to date.  Our IBNR reserves are calculated as 
the difference between our total reserves and the outstanding case reserves at the end of the accounting period.  To 
determine ultimate losses, our actuaries calculate a range of indications and select a point estimation using such actuarial 
techniques as: 

Paid Loss Indications: This method projects ultimate loss estimates based upon extrapolations of 
historic paid loss trends. This method tends to be used on short tail lines such as automobile physical 
damage. 

Incurred Loss Indications: This method projects ultimate loss estimates based upon extrapolations of 
historic incurred loss trends.  This method tends to be used on long tail lines of business such as 
automobile liability and homeowner’s liability. 

Bornhuetter-Ferguson Indications: This method projects ultimate loss estimates based upon 
extrapolations of an expected amount of IBNR, which is added to current incurred losses or paid 
losses.  This method tends to be used on small, immature, or volatile lines of business, such as our 
BOP and umbrella lines of business. 

Bodily Injury Code Indications: This method projects ultimate loss estimates for our private passenger 
and commercial automobile bodily injury coverage based upon extrapolations of the historic number of 
accidents and the historic number of bodily injury claims per accident. Projected ultimate bodily injury 
claims are then segregated into expected claims by type of injury (e.g. soft tissue injury vs. hard tissue 
injury) based on past experience.  An ultimate severity, or average paid loss amounts, is estimated 
based upon extrapolating historic trends. Projected ultimate loss estimates using this method are the 
aggregate of estimated losses by injury type. 

52 
 Such techniques assume that past experience, adjusted for the effects of current developments and anticipated 
trends, is an appropriate basis for predicting our ultimate losses, total reserves and resulting IBNR reserves.  It is possible 
that the final outcome may fall above or below these amounts as a result of a number of factors, including immature data, 
sparse data, or significant growth in a line of business.  Using these methodologies our actuaries established a range of 
reasonably possible estimations for net reserves of approximately $497,512 to $566,772 as of December 31, 2024 
compared to a range of $449,272 to $511,724 as of December 31, 2023.  In general, the low and high values of the 
ranges represent reasonable minimum and maximum values of the indications based on the techniques described above. 
Our selected point estimate of net loss and loss adjustment expense reserves based upon the analysis of our actuaries was 
$540,877 as of December 31, 2024 compared to $490,458 as of December 31, 2023. 
 The following table presents the point estimation of the recorded reserves and the range of estimations by line

At December 31, 2024 and 2023, our total IBNR reserves for our private passenger automobile line of business 
were comprised of ($98,528) and ($87,456) related to estimated ultimate decreases in the case reserves, including 
anticipated recoveries (i.e. salvage and subrogation), and $41,462 and $34,170 related to our estimation for not yet 
reported losses, respectively. 
Our IBNR reserves consist of our estimate of the total loss reserves required less our case reserves.  The IBNR 
reserves for CAR assumed commercial automobile business are 37.9% of our total reserves for CAR assumed 
commercial automobile business as of December 31, 2024 due to the reporting delays in the information we receive from 
CAR, as described further in the section on Residual Market Loss and Loss Adjustment Expense Reserves.
 The following table presents information by line of business for our total net reserves and the corresponding

Residual Market Loss and Loss Adjustment Expense Reserves
We are a participant in CAR and other various residual markets and assume a portion of losses and LAE on 
business ceded by the industry participants to the residual markets. We were a participant in the FAIR Plan until the 
recent FAIR Plan Restructuring.  We estimate reserves for assumed losses and LAE that have not yet been reported to us 
by the residual markets.  Our estimations are based upon the same factors we use for our own reserves, plus additional 
factors due to the nature of and the information we receive.   
Residual market deficits consist of premium ceded to the various residual markets less losses and LAE and is 
allocated among insurance companies based on a various formulas (the “Participation Ratio”) that take into consideration 
a company’s voluntary market share. 
Because of the lag in the various residual market estimations, and in order to try to validate to the extent 
possible the information provided, we estimate the effects of the actions of our competitors in order to establish our 
Participation Ratio.  
Although we rely to a significant extent in setting our reserves on the information the various residual markets 
provide, we are cautious in our use of that information, because of the delays in receiving data from the various residual 
markets.  As a result, we have to estimate our Participation Ratio and these reserves are subject to significant judgments 
and estimates. 
Sensitivity Analysis
Establishment of appropriate reserves is an inherently uncertain process.  There can be no certainty that 
currently established reserves based on our key assumptions regarding frequency and severity in our lines of business, or 
our assumptions regarding our share of the CAR loss 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.  For the twelve months ended 
December 31, 2024, a 1 percentage-point change in the loss and LAE ratio would result in a change in reserves of 
$10,110.  Each 1 percentage-point change in the loss and loss expense ratio would have had a $7,987 effect on net 
income, or $0.54 per diluted share. 
Our assumptions consider that past experience, adjusted for the effects of current developments and anticipated 
trends, are an appropriate basis for establishing our reserves.  Our individual key assumptions could each have a 
reasonable possible range of plus or minus 5 percentage-points for each estimation, although there is no guarantee that 
our assumptions will not have more than a 5 percentage point variation.  The following sensitivity tables present 
information for each of our primary lines of business on the effect each 1 percentage-point change in each of our key 
assumptions on unpaid frequency and severity could have on our retained (i.e., direct minus ceded) loss and LAE 
reserves and net income for the twelve months ended December 31, 2024.  In evaluating the information in the table, it 
should be noted that a 1 percentage-point change in a single assumption would change estimated reserves by 1 

54 
percentage-point.  A 1 percentage-point change in both our key assumptions would change estimated reserves within a 
range of plus or minus 2 percentage-points.

Our estimated share of CAR loss and LAE reserves is based on assumptions about our Participation Ratio, the 
size of CAR, and the resulting deficit.  Our assumptions consider that past experience, adjusted for the effects of current 
developments and anticipated trends, is an appropriate basis for establishing our CAR reserves.  Each of our assumptions 
could have a reasonably possible range of plus or minus 5 percentage-points for each estimation. 
The following sensitivity table presents information of the effect each 1 percentage-point change in our 
assumptions on our share of reserves for CAR and other residual markets could have on our assumed loss and LAE 
reserves and net income for the year ended December 31, 2024.  In evaluating the information in the table, it should be 
noted that a 1 percentage-point change in our assumptions would change estimated reserves by 1 percentage-point.

Reserve Development Summary
The changes we have recorded in our reserves in the past illustrate the uncertainty of estimating reserves.  Our 
prior year reserves decreased by $51,894, $47,381 and $57,279 during the years ended December 31, 2024, 2023, and 
2022, respectively. 
The following table presents a comparison of prior year development of our net reserves for losses and LAE for 
the years ended December 31, 2024, 2023 and 2022, respectively. Each accident year represents all claims for an annual 
accounting period in which loss events occurred, regardless of when the losses are actually reported, booked or 
paid.  Our financial statements reflect the aggregate results of the current and all prior accident years.

At the end of each period, the reserves were re-estimated for all prior accident years. Our prior year reserves 
decreased by $51,894, $47,381, and $57,279 for the years ended 2024, 2023, and 2022, respectively. The decreases in 
prior year reserves in 2024 resulted from re-estimations of prior years’ ultimate loss and LAE liabilities and are primarily 
composed of reductions of $12,742 in our retained automobile reserves and $29,286 in our retained other than auto and 
homeowner’s reserves. The decreases in prior year reserves in 2023 resulted from re-estimations of prior year’s ultimate 
loss and LAE liabilities and are primarily composed of reductions of $15,451 in our retained automobile reserves and 
$29,782 in our retained other than auto and homeowner reserves. The decrease in prior year reserves during 2022 are 
primarily composed of reductions of $20,241 in our retained automobile reserves and $32,963 in our retained 
homeowners reserves. It is not appropriate to extrapolate future favorable or unfavorable development of reserves from 
this past experience.

The improved retained private passenger and commercial automobile results were primarily due to fewer IBNR 
claims than previously estimated and better than previously estimated severity on our established bodily injury and 

57 
property damage case reserves.   Our retained other than auto and homeowners line of business prior year reserves 
decreased, due primarily to fewer IBNR claims than previously estimated.  
 In estimating all our loss reserves, we follow the guidance prescribed by ASC 944, Financial Services-
Insurance.

facts.  They often include words such as “believe,” “expect,” “anticipate,” “intend,” “plan,” “estimate,” “aim,” 
“projects,” or words of similar meaning and expressions that indicate future events and trends, or future or conditional 
verbs such as “will,” “would,” “should,” “could,” or “may.”  All statements that address expectations or projections 
about the future, including statements about the Company’s strategy for growth, product development, market position, 
expenditures and financial results, are forward-looking statements. 
Forward-looking statements are not guarantees of future performance.  By their nature, forward-looking 
statements are subject to risks and uncertainties.  There are a number of factors, many of which are beyond our control, 
that could cause actual future conditions, events, results or trends to differ significantly and/or materially from historical 
results or those projected in the forward-looking statements.  These factors include but are not limited to: 

The competitive nature of our industry and the possible adverse effects of such competition;   

Conditions for business operations and restrictive regulations in Massachusetts; 

The possibility of losses due to claims resulting from severe weather; 

The impact of inflation and supply chain delays on loss severity; 

The possibility that the Commissioner may approve future rule changes that change the operation of 
the residual market; 

The possibility that existing insurance-related laws and regulations will become further restrictive in 
the future; 

Our possible need for and availability of additional financing, and our dependence on strategic 
relationships, among others;  

Other risks and factors identified from time to time in our reports filed with the SEC.  Refer to 
Part I, Item 1A — Risk Factors. 
Some other factors, such as market, operational, liquidity, interest rate, equity and other risks, are described 
elsewhere in this Annual Report on Form 10-K. Factors relating to the regulation and supervision of our Company are 
also described or incorporated in this report.  There are other factors besides those described or incorporated in this 
report that could cause actual conditions, events or results to differ from those in the forward-looking statements.

statements to reflect circumstances or events that occur after the date the forward-looking statements are made. 
ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Market Risk.  Market risk is the risk that we will incur losses due to adverse changes in market rates and prices.  
We have exposure to market risk through our investment activities and our financing activities. Our primary market risk 
exposure is to changes in interest rates. We use both fixed and variable rate debt as sources of financing.  We have not 
entered, and do not plan to enter, into any derivative financial instruments for trading or speculative purposes. 
Interest Rate Risk.  Interest rate risk is the risk that we will incur economic losses due to adverse changes in 
interest rates.  Our exposure to interest rate changes primarily results from our significant holdings of fixed rate 
investments and from our financing activities. Our fixed maturity investments include U.S. and foreign government 
bonds, securities issued by government agencies, obligations of state and local governments and governmental 
authorities, corporate bonds and asset-backed securities, most of which are exposed to changes in prevailing interest 
rates. 
We manage our exposure to risks associated with interest rate fluctuations through active review of our 
investment portfolio by our management and Board and consultation with third-party financial advisors.  As a general 
matter, we do not attempt to match the durations of our assets with the durations of our liabilities, and the majority of our 
liabilities are “short tail.”  Our goal is to maximize the total after-tax return on all of our investments. An important 
strategy that we employ to achieve this goal is to try to hold enough in cash and short-term investments in order to avoid 
liquidating longer-term investments to pay claims. 
Based upon the results of interest rate sensitivity analysis, the following table shows the interest rate risk of our 
investments in fixed maturities, measured in terms of fair value (which is equal to the carrying value for all our fixed 
maturity securities).

With respect to floating rate debt, we are exposed to the effects of changes in prevailing interest rates.  At 
December 31, 2024, we had no debt outstanding under our credit facility.  Assuming the full utilization of our current 
available credit facility, a 2.0% increase in the prevailing interest rate on our variable rate debt would result in interest 
expense increasing approximately $600 for 2024, assuming that all of such debt is outstanding for the entire year. 
In addition, in the current market environment, our investments can also contain liquidity risks. 
Equity Risk.  Equity risk is the risk that we will incur economic losses due to adverse changes in equity prices.  
Our exposure to changes in equity prices results from our holdings of common stock and mutual funds held to fund the 
executive deferred compensation plan.  We continuously evaluate market conditions and we expect in the future to 
purchase additional equity securities.  We principally manage equity price risk through industry and issuer diversification 
and asset allocation techniques.

Report of Independent Registered Public Accounting Firm 
To the shareholders and the Board of Directors of Safety Insurance Group, Inc. 
Opinions on the Financial Statements and Internal Control over Financial Reporting 
We have audited the accompanying consolidated balance sheets of Safety Insurance Group, Inc. and subsidiaries (the 
"Company") as of December 31, 2024 and 2023, the related consolidated statements of operations, comprehensive 
income (loss), changes in shareholders’ equity, and cash flows, for each of the three years in the period ended December 
31, 2024, and the related notes and the schedules listed in the Index at Item 15 (collectively referred to as the "financial 
statements"). We also have audited the Company’s internal control over financial reporting as of December 31, 2024, 
based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring 
Organizations of the Treadway Commission (COSO). 
In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of 
the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the three 
years in the period ended December 31, 2024, in conformity with accounting principles generally accepted in the United 
States of America. Also, in our opinion, the Company maintained, in all material respects, effective internal control over 
financial reporting as of December 31, 2024, based on criteria established in Internal Control — Integrated Framework 
(2013) issued by COSO. 
Basis for Opinions 
The Company’s management is responsible for these financial statements, for maintaining effective internal control over 
financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the 
accompanying Item 9A. Controls and Procedures. Our responsibility is to express an opinion on these financial 
statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a 
public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and 
are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the 
applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. 
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and 
perform the audits to obtain reasonable assurance about whether the financial statements are free of material 
misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was 
maintained in all material respects. 
Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the 
financial statements, whether due to error or fraud, and performing procedures to respond to those risks. Such procedures 
included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our 
audits also included evaluating the accounting principles used and significant estimates made by management, as well as 
evaluating the overall presentation of the financial statements. Our audit of internal control over financial reporting 
included obtaining an understanding of internal control over financial reporting, assessing the risk that a material 
weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the 
assessed risk. Our audits also included performing such other procedures as we considered necessary in the 
circumstances. We believe that our audits provide a reasonable basis for our opinions. 
Definition and Limitations of Internal Control over Financial Reporting 
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding 
the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with 
generally accepted accounting principles. A company’s internal control over financial reporting includes those policies 
and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the 
transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are 
recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting 
principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of 

61 
management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely 
detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the 
financial statements. 
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. 
Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become 
inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may 
deteriorate. 
Critical Audit Matter 
The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements 
that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or 
disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or 
complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial 
statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate 
opinion on the critical audit matter or on the accounts or disclosures to which it relates. 
Losses and Loss Adjustment Expense Reserves – Refer to Notes 2 and 12 to the financial statements 
Critical Audit Matter Description 
The Company establishes loss and loss adjustment expense 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. The loss and loss adjustment expense reserves are determined in accordance with 
commonly accepted actuarial reserving techniques on the basis of the Company’s historical information and experience. 
In determining the loss and loss adjustment expense reserves, the Company analyzes historical data and estimates the 
impact of various loss development factors, such as the Company’s historical loss experience and that of the industry, 
trends in claims frequency and severity, the Company’s mix of business, the Company’s claims processing procedures, 
legislative enactments, judicial decisions, legal developments in imposition of damages, and changes and trends in 
general economic conditions, including the effects of inflation.   
Given the subjectivity associated with assumptions and methodologies used in determining the estimated ultimate cost to 
settle the liabilities for certain long tail reported and unreported losses due to uncertainties caused by various factors 
including frequency and severity of claims, as well as future legislative, judicial, and legal uncertainties, performing 
audit procedures to evaluate whether the ultimate cost of loss and loss adjustment expense reserves were appropriately 
recorded as of December 31, 2024, required a high degree of auditor judgment and an increased extent of effort, 
including the need to involve our actuarial specialists. 
How the Critical Audit Matter was Addressed in the Audit 
Our audit procedures related to certain loss and loss adjustment expense reserves included the following, among others:  
1. We tested the effectiveness of the Company’s controls related to loss and loss adjustment expense reserves, 
including controls over inputs, methods, and assumptions used in the Company’s estimation process. 
2. We tested the underlying data that served as the basis for the Company’s analysis, including historical claims, to 
test that the inputs to the actuarial estimate were complete and accurate.  
3. With the assistance of our actuarial specialists, we evaluated the methods and assumptions used by the 
Company to estimate ultimate losses incurred in determining loss and loss adjustment expense reserves by: 
a. 
Assessing the reasonableness of the Company’s analysis, developing independent estimates of loss and 
loss adjustment expense reserves and comparing such estimates to the Company’s recorded loss and 
loss adjustment expense reserves.  

62 
b. Comparing the Company’s prior year estimates of expected incurred losses to actual experience during 
the current year to identify potential management bias in the determination of loss and loss adjustment 
expense reserves.

1. 
Basis of Presentation 
The consolidated financial statements have been prepared on the basis of accounting principles generally

Group, Inc. and its subsidiaries (the “Company”). The subsidiaries consist of Safety Insurance Company, Safety 
Indemnity Insurance Company, Safety Property and Casualty Insurance Company, Safety Northeast Insurance Company, 
Safety Northeast Insurance Agency, Inc. (“SNIA”), and Safety Management Corporation (“SMC”), which is SNIA’s 
holding company.  
The Company was incorporated on June 25, 2001 in the State of Delaware. On October 16, 2001, the Company 
acquired all of the issued and outstanding common stock of Thomas Black Corporation (“TBC”) and its property and 
casualty subsidiaries. TBC subsequently merged with and into Safety Insurance Group, Inc. with Safety Insurance 
Group, Inc. being the corporation surviving the merger.

Maine. The Company’s principal product line is private passenger automobile insurance, which accounted for 55.8% of 
its direct written premiums in 2024. The Company primarily operates through its insurance company subsidiaries, Safety 
Insurance Company, Safety Indemnity Insurance Company, Safety Property and Casualty Insurance Company, and 
Safety Northeast Insurance Company (together referred to as the “Insurance Subsidiaries”). 
SNIA was established on December 1, 2022, when the Company acquired the assets and operations of 
Northeast Metrowest Insurance Agency, Inc. (“Northeast / Metrowest”), an independent insurance agency, through its 
wholly-owned subsidiary, SMC.  SNIA provides personal and commercial property and casualty insurance products to 
customers on behalf of the Insurance Subsidiaries and third-party insurance carriers.  All intercompany commission 
transactions, including commission income and underwriting, operating and related expenses, have been eliminated. 
Eliminated commission income totaled $1,069 and $963 for the years ended December 31, 2024 and 2023, respectively. 
As of December 31, 2024, fiduciary assets held by SNIA were immaterial and less than $150.  
As part of the purchase of SNIA, the Company paid cash and reissued treasury stock of $5,000.      
Since 1998, the Company had been a member of the Massachusetts Property Insurance Underwriting 
Association (“FAIR Plan”). The FAIR Plan was a residual market insurance association in which all companies writing 
basic property insurance in the Commonwealth of Massachusetts were required to participate, with profits and losses 
shared among member companies on a written premium basis. On April 1, 2024, the Massachusetts Division of 
Insurance approved a restructuring of the FAIR Plan (“FAIR Plan Restructuring”), transforming it from a partnership 
that shares profit and losses with member companies to a stand-alone, risk bearing entity, and distributing the 
accumulated members’ equity. As a result of the FAIR Plan Restructuring, the Company recognized an underwriting 
gain through the release of prior year loss reserves, (“FAIR Plan Development”) and established a new invested asset, 
(“Investment in FAIR Plan Trust”).

Summary of Significant Accounting Policies 
Investments 
Investments in fixed maturities, which include taxable and non-taxable bonds and redeemable preferred stocks, 
are reported at fair value. Fair values for fixed maturity securities are based on estimates obtained from independent 
pricing services. Unrealized gains or losses on fixed maturity securities reported at fair value are excluded from earnings 
and reported in a separate component of shareholder’s equity known as “accumulated other comprehensive income net of 
taxes” until realized. For fixed maturities that the Company does not intend to sell or for which it is more likely than not 

69 
that the Company would not be required to sell before an anticipated recovery in value, the Company separates the credit 
loss component of the impairment from the amount related to all other factors and reports the credit loss component as 
credit loss expense.  The impairment related to all other factors (non-credit factors) is reported in accumulated other 
comprehensive income. The allowance for expected credit losses is adjusted for any additional credit losses and 
subsequent recoveries. Upon recognizing a credit loss, the cost basis is not adjusted. See Note 3 for further details of the 
Company’s accounting for impairments of available-for-sale investments. 
Investments in equity securities, which include interests in common stocks, mutual funds and a real estate 
investment trust (“REIT”), are reported at fair value. Fair values for equity securities are derived from external market 
quotations, with the exception of the REIT whose fair value was determined using the trust’s net asset value obtained 
from its audited financial statements. Changes in unrealized gains or losses on equity securities are recognized in 
earnings. 
Other invested assets consist of investments in limited partnerships. The partnership interest is accounted for 
using the equity method of accounting and recorded in earnings from partnership investments. The carrying value of 
these investments are written down, or impaired, to fair value when a decline in value is considered to be 
other-than-temporary. In applying the equity method (including assessment for other-than-temporary impairment), the 
Company uses financial information provided by the investee, generally on a three-month lag.  
As an element of the FAIR Plan Restructuring, in a non-cash transaction, the Company liquidated its net asset 
position in the FAIR Plan and established Investment in FAIR Plan Trust. The Company’s Investment in FAIR Plan 
Trust is adjusted to its current fair value on a quarterly basis based on information from the FAIR Plan, with changes 
recognized through earnings. As of December 31, 2024, the Company’s Investment in FAIR Plan Trust of $14,477 was 
included in other invested assets. As of December 31, 2024, the Company recognized $247 of income in earnings from 
partnership investments from its Investment in FAIR Plan Trust.   
Realized gains or losses on the sale or maturity of investments are determined based on the specific cost 
identification method.  
Investment income is recognized on an accrual basis of accounting. Bonds not backed by other loans are 
amortized using the interest method. Loan-backed bonds and structured securities are amortized using the interest 
method and significant changes in estimated cash flows from the original purchase assumptions are accounted for using 
the retrospective method. 
Cash and Cash Equivalents 
Cash and cash equivalents includes money market accounts and U.S. Treasury bills with original maturities of 
three months or less from the date of purchase. U.S. Treasury bills are stated at amortized cost, which approximates fair 
value. 
Accounts Receivable 
Amounts included in accounts receivable represent premiums as well as finance charges, the majority of which 
are billed on a monthly installment basis. Accounts receivable are stated net of allowances for doubtful accounts. At 
December 31, 2024 and 2023, these allowances were $918 and $1,053, respectively. Uncollected premium balances over 
ninety days past due are written off. 
Deferred Policy Acquisition Costs 
Amounts that vary with and are primarily related to the successful acquisition of a new or renewal insurance 
contract, principally commissions, premium taxes and certain other costs, are deferred and amortized ratably over the 
effective period of the policy. All other acquisition expenses are expensed as incurred. Deferred policy acquisition costs 
are reviewed to determine if they are recoverable from future income, and if not, are charged to expense. Future 
investment income attributable to related premiums is not taken into account in measuring the recoverability of the 

70 
carrying value of this asset. Amortization of acquisition costs in the amount of $207,016, $161,630 and $146,013 were 
included in underwriting, operating and other expenses for the years ended 2024, 2023 and 2022, respectively. 
Equity and Deposits in Pools 
Equity and deposits in pools represents the net receivable amounts from the residual market mechanisms, 
Commonwealth Automobile Reinsurers (“CAR”) for automobile and Massachusetts Property Insurance Underwriting 
Association (“FAIR Plan”) for homeowners insurance in Massachusetts. See Note 11 for a discussion of the Company’s 
accounting for amounts assumed from residual markets. 
As an element of the FAIR Plan Restructuring, the Company eliminated its net asset position in FAIR Plan, 
which was included within equity and deposits in pools. As a result, the Company’s equity and deposits in pools balance 
no longer includes a net receivable balance from FAIR Plan as of December 31, 2024.  
Equipment and Leasehold Improvements 
Property, equipment, leasehold improvements, and software which are included in other assets are carried at 
cost less accumulated depreciation. Depreciation is provided using the straight- line or accelerated method over the 
estimated useful lives of the related assets, which range from 3 to 10 years. Amortization of leasehold improvements is 
provided using the straight-line method over the term of the lease. The costs of computer software developed or obtained 
for internal use are capitalized and amortized over the estimated life of the business system, beginning when the software 
is ready for its intended use. Maintenance and repairs are charged to expense as incurred. 
Business Combinations 
The Company accounts for acquisitions of entities that qualify as businesses using the acquisition method of 
accounting in accordance with Accounting Standards Codification (“ASC”) 805, Business Combinations.  Purchase 
consideration is allocated to the assets acquired, including customer relationship intangible assets, and liabilities assumed 
based on their estimated fair values at acquisition.  Management estimated the fair value of such intangible assets using 
an income approach that considered cash flows expected to be generated by the acquired business relationships, a 
weighted average cost of capital discount rate reflecting the relative risk of achieving the anticipated cash flows, profits, 
the time value of money, and other relevant inputs.  The excess of the total purchase consideration over the fair value of 
the identified net assets acquired is recognized as goodwill.  The results of acquired businesses are included in the results 
of operations beginning from the date of acquisition.  Acquisition related costs are expensed as incurred.  During the 
measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the 
allocation of purchase consideration and to the fair values of assets acquired and liabilities assumed to the extent that 
additional information becomes available.  After this period, any subsequent adjustments are recorded in earnings.  
Goodwill  
Goodwill generated through acquisition is carried at cost, net of impairments.  Goodwill is not amortized but is 
reviewed for impairment at least annually or more frequently when indicators of potential impairment exist.  
Management first evaluates impairment of goodwill by assessing qualitative factors to determine whether it is more 
likely than not that the fair value of a reporting unit is less than its carrying amount.  If after performing the qualitative 
assessment, management determines it is more likely than not that the fair value of the reporting unit is less than its 
carrying amount, a quantitative assessment to determine the fair value of the reporting unit.  Management’s 
determination of the fair value of the reporting unit incorporates multiple inputs into discounted cash flow calculations, 
including levels of economic capital required to support the business, future business growth, earnings projections, and 
the weighted average cost of capital used for purposes of discounting.  Goodwill is impaired up to the amount that the 
carrying value of the reporting unit exceeds the fair value.  The Company did not recognize any goodwill impairments 
during the year ended December 31, 2024.

71 
Intangible Assets 
Acquired intangible assets are amortized over their useful lives on a straight-line basis over the period of 
expected benefit, generally 10 years.  The Company recognized $885, $816 and $44 of amortization expense for the 
years ended December 31, 2024, 2023 and 2022, respectively, and expects to recognize $885 of amortization expense 
annually.  Intangible assets are assessed for impairment generally when events or circumstances indicate a potential 
impairment.  If it is determined that the carrying amount of the asset is not recoverable, the asset is written down to fair 
value and an impairment loss is recognized.  The Company did not identify any impairment indicators during the year 
ended December 31, 2024.
Revenue Recognition 
The Company recognizes revenue under both ASC 944, Financial Services – Insurance (“ASC 944”) and ASC 
606, Revenue from Contracts with Customers (“ASC 606”). 
Premiums are earned over the terms of the respective policies, which are generally one year.  Unearned 
premiums represent the portion of premiums written applicable to the unexpired terms of the policies. 
Ceded premiums are charged to income over the terms of the respective policies and the applicable term of the 
reinsurance contracts with third-party reinsurers. Ceded unearned premiums represent the unexpired portion of premiums 
ceded to CAR and other reinsurers. 
Premiums received in advance of the policy effective date are recorded as a liability and not recognized as 
income until earned. Such amounts are included in accounts payable and accrued liabilities and totaled $10,144 and 
$11,983 at December 31, 2024 and 2023, respectively. 
Finance and other service income primarily include revenues from premium installment charges, which are 
recognized when earned. 
Commission revenue includes new and renewal commissions paid by insurance carriers.  These commissions 
are earned at the later of the effective date or billing date, as all rights are passed to the insured, the obligation to pay a 
claim resides with the insurance carrier, and no further performance obligation exists for the Company. Under the terms 
of its contracts with insurance carriers, the Company can earn additional, variable commission revenue in the form of 
annual contingent underwriting commissions (“CUC”) based on the underwriting performance of the insurance book of 
business.  Each carrier contract and related CUC is calculated independently.  Under ASC 606, the Company must 
estimate the amount of consideration that will be received in the coming year such that a significant reversal of revenue 
is not probable.  As such, CUC is recognized as a contract asset as policies are issued using applicable premium and 
payout factors based on the estimated loss ratio from the contract.      
Losses and Loss Adjustment Expenses 
Liabilities for losses and loss adjustment expenses (“LAE”) include case basis estimates for open claims 
reported prior to year-end and estimates of unreported claims and claim adjustment expenses, net of salvage and 
subrogation. The estimates are continually reviewed and modified to reflect current conditions, and any resulting 
adjustments are reflected in current operating results. Adjustments for anticipated salvage and subrogation are recorded 
on incurred and reported and incurred but not reported losses.   
The Company determines its loss and LAE reserves estimate based upon the analysis of our actuaries.  A 
reasonable estimate is derived by selecting a point estimate within a range of indications as calculated by our actuaries 
using generally accepted actuarial techniques. The key assumption in most actuarial analysis is that past patterns of 
frequency and severity will repeat in the future, unless a significant change in the factors described above takes place.  
Our key factors and resulting assumptions are the ultimate frequency and severity of claims, based upon the most recent 
ten years of claims reported to the Company, and the data reported to us to calculate our share of the residual market.  
For each accident year and each coverage within a line of business our actuaries calculate the ultimate losses incurred. 

72 
Reinsurance 
Liabilities for unearned premiums and unpaid losses are stated before deductions for ceded reinsurance. The 
ceded amounts are carried as receivables. Earned premiums are stated net of deductions for ceded reinsurance. 
The Company, as primary insurer, will be required to pay losses in their entirety in the event that the reinsurers 
are unable to discharge their obligations under the reinsurance agreements. 
Advertising Costs 
Advertising costs are charged to expense when they are incurred. Total advertising costs were $2,125, $2,405 
and $2,399 for the years ended December 31, 2024, 2023, and 2022, respectively, and are included in underwriting, 
operating and related expenses.   
Income Taxes 
The Company and its subsidiaries file a consolidated U.S. federal income tax return. The method of allocation 
among members of the consolidated group is subject to a written agreement approved by the Board of Directors (the 
“Board”). The consolidated tax liability is allocated on the basis of the members’ proportionate contribution to 
consolidated taxable income. 
Deferred income taxes are generally recognized when assets and liabilities have different values for financial 
statement and tax reporting purposes, and for other temporary taxable and deductible differences as defined by ASC 740, 
Income Taxes. A valuation allowance is established where management has assessed that it is more likely than not that 
the Company will not be able to utilize the full deferred tax asset. 
Earnings per Weighted Average Common Share 
Basic earnings per weighted average common share (“EPS”) are calculated by dividing net income by the 
weighted average number of basic common shares outstanding during the period.  Diluted earnings per share amounts 
are based on the weighted average number of common shares including non-vested performance stock grants.

Diluted EPS excludes non vested performance stock grants with exercise prices and exercise tax benefits greater 
than the average market price of the Company’s common stock during the period because their inclusion would be 
anti-dilutive. There were no anti-dilutive non-vested performance stock grants for the years ended December 31, 2024, 
2023 and 2022. 
Share-Based Compensation 
ASC 718, Compensation —Stock Compensation (“ASC 718”), requires the Company to measure and recognize 
the cost of employee services received in exchange for an award of equity instruments.  Under the provisions of ASC 
718, share-based compensation cost is measured at the grant date, based on the fair value of the award, and is recognized 
as an expense over the requisite service period (generally the vesting period of the equity grant). 
See Note 7 for further information regarding share-based compensation. 
Use of Estimates 
The preparation of financial statements in conformity with GAAP requires management to make estimates and 
assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at 
the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Actual 
results could differ from those estimates. 
Recent Accounting Pronouncements 
In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 
(“ASU”) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. This ASU 
updates reportable segment disclosures primarily through enhanced disclosures about significant segment expenses. This 
ASU does not change how a Company identifies its operating segments, aggregates those operating segments, or applies 
the quantitative thresholds to determine its reportable segments. This ASU is effective for fiscal years starting January 1, 
2024, and for interim periods starting January 1, 2025, and will be applied on a retrospective basis. The Company 
implemented this guidance effective January 1, 2024. The effect of implementing this guidance was not material to the 

74 
Company’s consolidated financial position, results of operations or cash flows.  
In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax 
Disclosures. This ASU updates the required income tax disclosures to include disclosure of income taxes paid 
disaggregated by jurisdiction and greater disaggregation of information in the required rate reconciliation. This ASU is 
effective for fiscal years starting January 1, 2025 and will be applied on a prospective basis. The Company is evaluating 
the disclosure impact of this new guidance; however, it will not have an impact on the consolidated financial position, 
results of operations, or cash flows. 
In November 2024, the FASB issued ASU 2024-03, Income Statement – Reporting of Comprehensive Income – 
Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. This ASU 
requires disaggregated disclosure of income statement expenses. This ASU does not change how a Company presents 
expense captions on the face of the income statement; however, it requires disaggregation of certain expense captions 
into specified categories in disclosures in the footnotes to the financial statements. This ASU is effective for fiscal years 
starting January 1, 2027, and for interim periods starting January 1, 2028 and will be applied on a prospective basis. The 
Company is evaluating the disclosure impact of this new guidance; however, it will not have an impact on the 
consolidated financial position, results of operations, or cash flows.  
Segments 
The Company has one reportable operating segment, property and casualty insurance operations. Property and 
casualty insurance operations accounted for substantially all of the Company’s operations in 2024, 2023, and 2022. The 
Company’s business is organized around private passenger automobile insurance in Massachusetts sold exclusively 
through independent agents and offers other personal and commercial insurance as complementary products. The 
accounting policies of the segment are the same as those described in the summary of significant accounting policies.  
The Company’s chief operating decision maker (“CODM”) is the chief executive officer. The CODM assesses 
performance for the property and casualty insurance operations segment and decides how to allocate resources based on 
consolidated net income, which is reported in the consolidated statements of operations. The significant segment 
expenses regularly provided and reviewed by the CODM are the consolidated expenses as reported in the consolidated 
statements of operations. The measure of segment assets is reported on the consolidated balance sheets as total assets. 
The CODM uses consolidated net income in deciding whether to reinvest profits into the property and casualty insurance 
operations or into other parts of the entity, such as for acquisitions or to pay dividends.

In the normal course of business, the Company enters into transactions involving various types of financial 
instruments, including investments in fixed maturities and equity securities. Investment transactions have credit exposure 
to the extent that a counter party may default on an obligation to the Company. Credit risk is a consequence of carrying, 
trading and investing in securities. To manage credit risk, the Company focuses on higher quality fixed income 
securities, reviews the credit strength of all companies in which it invests, limits its exposure in any one investment and 
monitors the portfolio quality, taking into account credit ratings assigned by recognized statistical rating organizations.

At December 31, 2024, U.S. Government residential mortgage backed securities with a fair value of $47,341 
are pledged as collateral for a borrowing with the Federal Home Loan Bank of Boston (“FHLB-Boston”) as described in 
Note 10 – Debt. These securities are included in fixed maturity securities on the Company’s Consolidated Balance 
Sheets.  
Impairments 
For fixed maturities that the Company does not intend to sell or for which it is more likely than not that the 
Company would not be required to sell before an anticipated recovery in value, the Company separates the credit loss 
component of the impairment from the amount related to all other factors. The expected credit loss component is 
recognized as an allowance for expected credit losses. The allowance is adjusted for any additional credit losses and 
subsequent recoveries, which are booked in income as either credit loss expense or credit loss benefit, respectively. Upon 
recognizing a credit loss, the cost basis is not adjusted. The impairment related to all other factors (non-credit factors) is 
reported in other comprehensive income. 
For fixed maturities where the Company records a credit loss, a determination is made as to the cause of the 
impairment and whether the Company expects a recovery in the value.  For fixed maturities where the Company expects 
a recovery in value, the constant effective yield method is utilized, and the investment is amortized to par. 
For fixed maturity investments the Company intends to sell or for which it is more likely than not that the 
Company will be required to sell before an anticipated recovery in value, the full amount of the impairment is included 
in credit loss expense. The new cost basis of the investment is the previous amortized cost basis less the impairment 
recognized in credit loss expense.  The new cost basis is not adjusted for any subsequent recoveries in fair value. 

77 
The Company uses a systematic methodology to evaluate declines in fair values below cost or amortized cost of 
our investments. Some of the factors considered in assessing impairment of fixed maturities due to credit losses include 
the extent to which the fair value is less than amortized cost, the financial condition of and the near and long-term 
prospects of the issuer, whether the debtor is current on its contractually obligated interest and principal payments, 
changes to the rating of the security by a rating agency, the historical volatility of the fair value of the security and 
whether it is more like than not that the Company will be required to sell the investment prior to an anticipated recovery 
in value.  
As of December 31, 2024, the Company concluded that $1,198 of unrealized losses were due to credit factors 
and were recorded as an allowance for expected credit losses, compared to $1,208 as of December 31, 2023. The 
Company concluded that outside of the securities that were recognized as credit impaired, the unrealized losses recorded 
on the fixed maturity portfolio at December 31, 2024 and 2023 resulted from fluctuations in market interest rates and 
other temporary market conditions as opposed to fundamental changes in the credit quality of the issuers of such 
securities.  Based upon the analysis performed, the Company’s decision to hold these securities, the Company’s current 
level of liquidity and our history of positive operating cash flows, management believes it is more likely than not that it 
will not be required to sell any of its securities before the anticipated recovery in the fair value to its amortized cost basis. 
The following tables represent a reconciliation of the beginning and ending balances of the allowance for 
expected credit losses on fixed maturities classified as available for sale.

Allowance for Expected Credit Losses 
 
The Company’s financial instruments include premiums and accounts receivable, and reinsurance recoverables. 
Premiums and accounts receivable are reported net of an allowance for expected credit losses. The allowance is 
based upon the Company’s ongoing review of amounts outstanding, historical loss data, including delinquencies and 
write-offs, current and forecasted economic conditions and other relevant factors. Credit risk is partially mitigated by the 

78 
Company’s ability to cancel the policy if the policyholder does not pay the premium and the Company writes off 
premiums receivable balances that are more than 90 days overdue. 
The following tables present the balances of premiums receivable, net of the allowance for expected credit 
losses, for the years ended December 31, 2024 and 2023, and changes in the allowance for expected credit losses for the 
years ended December 31, 2024 and 2023.

Reinsurance recoverables include amounts due from reinsurers for both paid and unpaid losses. The Company 
cedes insurance to CAR and to other reinsurers. The Company has a property catastrophe excess of loss agreement and a 
casualty excess of loss agreement that qualify as reinsurance treaties and are designed to protect against large or unusual 
loss and LAE activity. Reinsurance contracts do not relieve the Company from its obligations to policyholders. Failure of 
reinsurers to honor their obligations could result in losses to the Company. The Company evaluates the financial 
condition of its reinsurers and monitors economic characteristics of the reinsurers to minimize its exposure to significant 
losses from reinsurer insolvencies. The Company reports its reinsurance recoverables net of an allowance for estimated 
uncollectable reinsurance. A probability-of-default methodology which reflects current and forecasted economic 
conditions is used to estimate the amount of uncollectible reinsurance due to credit-related factors and the estimate is 
reported in an allowance for estimated uncollectible reinsurance. Amounts deemed to be uncollectible, including 
amounts due from known insolvent reinsurers, are written off against the allowance. Changes in the allowance, as well as 
any subsequent collections of amounts previously written off, are reported as part of claims and claim adjustment 
expenses.   
The majority of the Company’s reinsurance recoverable on paid and unpaid losses is a result of our participation 
as a servicing carrier in the CAR Commercial Automobile Program, which represents 93% and 94% of the total 
reinsurance recoverable on paid and unpaid losses at December 31, 2024 and 2023, respectively. The remaining 7% and 
6%, respectively, of amounts due from reinsurers are related to our other excess of loss and quota share contracts. For 
amounts due under these contracts, the Company utilizes updated A.M. Best credit ratings on a quarterly basis to 
determine the allowance for expected credit losses. As of December 31, 2024 and 2023, all reinsurers under these 
programs are rated “A” or better by A.M. Best. Certain of the Company's reinsurance recoverables are collateralized by 
letters of credit, funds held or trust agreements. The Company’s analysis concludes that there are no expected credit 
losses at December 31, 2024 or 2023.

6. 
Employee Benefit Plan 
The Company sponsors the Safety Insurance Company 401(k) qualified defined contribution retirement plan 
(the “Retirement Plan”).  The Retirement Plan is available to all eligible employees of the Company.  An employee must 
be 21 years of age to be eligible to participate in the Retirement Plan and is allowed to contribute on a pre-tax basis up to 
the maximum allowed under federal law.  The Retirement Plan is administered by the Company and is subject to the 
provisions of the Employee Retirement Income Security Act of 1974.  At the close of each Retirement Plan year, the 
Company makes a matching contribution equal to 100% of the amount each participant contributed during the plan year 
from their total pay, up to a maximum amount of 8% of the participant’s base salary, to those participants who have 
contributed to the Retirement Plan and were employed on the last day of the Retirement Plan year.  Compensation 
expense related to the Retirement Plan was $3,761, $3,788, and $3,382 for the years ended December 31, 2024, 2023, 
and 2022, respectively. 
7. 
Share-Based Compensation  
2018 Long Term Incentive Plan
On March 24, 2022, the Company’s Board of Directors adopted the Amended and Restated Safety Insurance 
Group, Inc. 2018 Long-Term Incentive Plan (“the Amended 2018 Plan”), which was subsequently approved by our 
shareholders at the 2022 Annual Meeting of Shareholders.  The Amended 2018 Plan increases the share pool limit by 
adding 350,000 common shares to the previously adopted Safety Insurance Group, Inc. 2018 Long-Term Incentive Plan.  
The Amended 2018 Plan enables the grant of stock awards, performance shares, cash-based performance units, other 
stock-based awards, stock options, stock appreciation rights, and stock unit awards, each of which may be granted 
separately or in tandem with other awards.  Eligibility to participate includes officers, directors, employees and other 
individuals who provide bona fide services to the Company.  The Amended 2018 Plan supersedes the Company’s 2002 
Management Omnibus Incentive Plan (“the 2002 Incentive Plan”).  
The Amended 2018 Plan establishes a pool of 700,000 shares of common stock available for issuance to our 
employees and other eligible participants. The Board of Directors and the Compensation Committee intend to issue 
awards under the Amended 2018 Plan in the future. 
The maximum number of shares of common stock between the Amended 2018 Plan and the 2002 Incentive 
Plan with respect to which awards may be granted is 3,200,000.  No further grants will be allowed under the 2002 
Incentive Plan.  At December 31, 2024, there were 364,912 shares available for future grant. 

80 
Restricted Stock  
Service-based restricted stock awarded in the form of unvested shares is recorded at the market value of the 
Company’s common stock on the grant date and amortized ratably as compensation expense over the requisite service 
period.  Service-based restricted stock awards generally vest over a three-year period and vest 30% on the first and 
second anniversaries of the grant date and 40% on the third anniversary of the grant date, except for non-executive 
employees’ restricted stock awards granted prior to 2018 which vest ratably over a five-year service period and 
independent directors’ stock awards which vest immediately.  Our independent directors are subject to stock ownership 
guidelines, which require them to have a value equal to four times their annual cash retainer. 
In addition to service-based awards, the Company grants performance-based restricted shares to certain 
employees.  These performance shares cliff vest after a three-year performance period provided certain performance 
measures are attained.  A portion of these awards, which contain a market condition, vest according to the level of total 
shareholder return achieved by the Company compared to its property-casualty insurance peers over a three-year period.  
The remainder, which contain a performance condition, vest according to the level of Company’s combined ratio results 
compared to a target based on its property-casualty insurance peers. 
Actual payouts can range from 0% to 200% of target shares awarded depending upon the level of achievement 
of the respective market and performance conditions during a three calendar-year performance period.  Compensation 
expense for share awards with a performance condition is based on the probable number of awards expected to vest 
using the performance level most likely to be achieved at the end of the performance period. 
Performance-based awards with market conditions are accounted for and measured differently from awards that 
have a performance or service condition.  The effect of a market condition is reflected in the award’s fair value on the 
grant date.  That fair value is recognized as compensation cost over the requisite service period regardless of whether the 
market-based performance objective has been satisfied. 
All of the Company’s restricted stock awards are issued as incentive compensation and are equity classified. 
The following table summarizes restricted stock activity under the Amended 2018 Plan assuming a target 
payout for the performance-based shares.

81 
 As of December 31, 2024, there was $4,884 of unrecognized compensation expense related to non-vested 
restricted stock awards that is expected to be recognized over a weighted average period of 1.5 years. The total fair value 
of the shares that were vested and unrestricted during the years ended December 31, 2024, 2023, and 2022 was $4,495, 
$5,456 and $5,749, respectively. For the years ended December 31, 2024, 2023, and 2022, the Company recorded 
compensation expense related to awards under the Incentive Plan of $3,542, $3,422, and $4,724, net of income tax 
benefit of $942, $910, and $1,256, respectively. 
8. 
Commitments and Contingencies  
Commitments 
As part of the Company’s investment activity, we have committed $170,000 to investments in limited 
partnerships.  The Company has contributed $144,682 to these commitments as of December 31, 2024.  As of 
December 31, 2024, the remaining committed capital that could be called is $34,033, which includes potential recallable 
capital distributions. 
Contingencies 
 Various claims, generally incidental to the conduct of normal business, are pending or alleged against the 
Company from time to time. In the opinion of management, based in part on the advice of legal counsel, the ultimate 
resolution of such claims will not have a material adverse effect on the Company’s consolidated financial statements. 
However, if estimates of the ultimate resolutions of those proceedings are revised, liabilities related to those proceedings 
could be adjusted in the near term.   
On October 19, 2021, the Supreme Judicial Court of Massachusetts (the “SJC”) unanimously ruled that property 
and casualty insurers must compensate third-party claimants under property damage coverage, part 4 of the standard 
Massachusetts automobile insurance policy, 2008 edition (standard policy), for the inherent diminished value (“IDV”) 
that occurs when their vehicles are damaged in a crash. This ruling overturned a previous decision by the Massachusetts 
Superior Court (the “Superior Court”), which found that a Massachusetts auto insurance policy did not provide property 
damage coverage for inherent diminished value damages for third-party claimants. The SJC placed the burden of proof 
on the individual claimant by explicitly specifying that the claimant must establish that the vehicle has suffered IDV 
damages and also the amount of IDV damages at issue. The SJC further ruled that an insurer’s previous denial of 
coverage for such damages could not serve as the basis for a claim of unfair business practices. On June 20, 2023, the 
Superior Court denied a motion brought by the plaintiffs seeking class certification. The plaintiffs had filed a motion to 
amend the complaint, seeking to address the concerns raised by the Superior Court in denying their motion for class 
certification, which Safety had opposed. The motion was denied, thus at this point, there will not be a renewed motion 
for class certification. Safety has not accrued for a specific loss contingency.  
Massachusetts law requires that insurers licensed to do business in Massachusetts participate in the 
Massachusetts Insurers Insolvency Fund (“Insolvency Fund”). Members of the Insolvency Fund are assessed a 
proportionate share of the obligations and expenses of the Insolvency Fund in connection with an insolvent insurer. It is 
anticipated that there will be additional assessments from time to time relating to various insolvencies. Although the 
timing and amounts of any future assessments are not known, based upon existing knowledge, management’s opinion is 
that such future assessments will not have a material effect upon the financial position of the Company. 

82 
9.  Leases 
The Company has various non-cancelable, long-term operating leases, the largest of which are for office space 
including the corporate headquarters, agency locations, VIP claims centers and law offices.  Other operating leases 
consist of auto leases and various office equipment.  The Company has no finance leases.  Our leases have remaining 
lease terms of one year to five years, some of which also include options to extend the leases for an additional five-year 
period. 
Certain lease agreements contain renewal options and, in addition to the minimum annual rentals, generally 
provide for payment of a share of the real estate taxes and operating expenses in excess of a base amount. Rental expense 
for our office space, law offices and VIP claims centers was $4,832, $4,294 and $3,948 for the years ended 
December 31, 2024, 2023, and 2022, respectively. All leases expire prior to 2029. The Company expects that in the 
normal course of business, leases that expire will be renewed. 
In calculating lease liabilities the Company uses its incremental borrowing rate as of the application date based 
on original lease terms. The components of lease expense were as follows:

Debt 
On August 10, 2023, the Company extended its Revolving Credit Agreement (the “Credit Agreement”) with 
Citizens Bank, N.A. (“Citizens Bank”) to a maturity date of August 10, 2028. The Credit Agreement provides a $30,000 
revolving credit facility with an accordion feature allowing for future expansion of the committed amount up to $50,000.  
Loans under the credit facility bear interest at the Company’s option at the higher of Citizens Bank prime rate, the SOFR 
rate plus 1.25% per annum, or 0.5% above the federal funds rate. Interest only is payable prior to maturity. 
The Company’s obligations under the credit facility are secured by pledges of its assets and the capital stock of 
its operating subsidiaries. The credit facility is guaranteed by the Company’s non-insurance company subsidiaries. The 
credit facility contains covenants including requirements to maintain minimum risk-based capital ratios and statutory 

83 
surplus of Safety Insurance Company as well as limitations or restrictions on indebtedness, liens, and other matters. As 
of December 31, 2024, the Company was in compliance with all covenants. In addition, the credit facility includes 
customary events of default, including a cross-default provision permitting the lenders to accelerate the facility if the 
Company (i) defaults in any payment obligation under debt having a principal amount in excess of $10,000 or (ii) fails to 
perform any other covenant permitting acceleration of all such debt. 
The Company had no amounts outstanding on its credit facility at December 31, 2024 or 2023.  The credit 
facility commitment fee included in interest expense was computed at a rate of 0.20% and 0.25% per annum on the 
$30,000 commitment at December 31, 2024 and 2023, respectively. 
The Company is a member of the FHLB-Boston.  Membership in the FHLB-Boston allows the Company to 
borrow money at competitive interest rates provided the loan is collateralized by specific U.S Government residential 
mortgage backed securities.  At December 31, 2024, the Company has the ability to borrow approximately $226,082 
using eligible invested assets that would be used as collateral.  
On March 17, 2020, the Company borrowed $30,000 from the FHLB-Boston for a term of five-years, bearing 
interest at a rate of 1.42%. Interest is payable monthly and the principal is due on the maturity date of March 17, 2025 
but may be prepaid in whole or in part by the Company in advance with a minor penalty for prepayment.

respectively.  The loans are fully collateralized by specific U.S. Government residential mortgage-backed securities with 
a fair value of $47,341 and $53,503 at year ended December 31, 2024 and 2023, respectively. The borrowing is 
outstanding from the FHLB-Boston at year ended December 31, 2024 and 2023. 
Interest expense was $509 and $818 for the years ended December 31, 2024 and 2023, respectively. 
11. 
Reinsurance 
The Company cedes insurance to CAR and to other reinsurers. The Company has various excess of loss and 
quota share agreements that qualify as reinsurance treaties and are designed to protect against large or unusual loss and 
LAE activity. Reinsurance contracts do not relieve the Company from its obligations to policyholders. Failure of 
reinsurers to honor their obligations could result in losses to the Company. The Company evaluates the financial 
condition of its reinsurers and monitors economic characteristics of the reinsurers to minimize its exposure to significant 
losses from reinsurer insolvencies. 

84 
The Company is subject to concentration of credit risk with respect to reinsurance ceded. At December 31, 
2024, reinsurance receivables on paid and unpaid loss and LAE with a carrying value of $145,927 and ceded unearned 
premiums of $38,335 were associated with CAR. At December 31, 2023, reinsurance receivables on paid and unpaid 
loss and LAE with a carrying value of $116,008 and ceded unearned premiums of $29,890 were associated with CAR. 
The Company assumes a proportionate share of the obligations from CAR. The Company makes an estimate of its share 
of assumed activity from the most recent quarter reported by CAR and records adjustments to the reported activity to 
reflect its anticipated final assumed obligations. The Company’s participation in CAR resulted in assumed net income of 
$2,738, $100 and $3,326 for the years ended December 31, 2024, 2023 and 2022, respectively. 
CAR has been, with few exceptions, required by law to issue a policy to any applicant who seeks it. As a 
servicing carrier of CAR, this requirement has applied to the Company. 
The effect of assumed and ceded premiums on net written and earned premiums and losses and LAE incurred is 
as follows.

At the end of each period, the reserves were re-estimated for all prior accident years. The Company’s prior year 
reserves decreased by $51,894, $47,381, and $57,279, for the years ended December 31, 2024, 2023, and 2022, 
respectively, and resulted from re-estimations of prior years’ ultimate loss and LAE liabilities. The decrease in prior year 

85 
reserves during 2024 was primarily composed of reductions of $12,742 in the Company’s retained automobile and 
$29,286 in the Company’s retained other than auto and homeowners reserves. The decrease in prior year reserves during 
2023 was primarily composed of reductions of $15,451 in the Company’s retained automobile and $29,782 in the 
Company’s retained other than auto and homeowners reserves. The decrease in prior year reserves during 2022 was 
primarily composed of reductions of $20,241 in the Company’s retained automobile and $32,963 in the Company’s 
retained other than auto and homeowners reserves. 
As of June 30, 2024, the Company carried $11,802 of reserves for losses and LAE related to participation in the 
FAIR Plan, and a total net asset of $13,254 representing its estimated share of members’ equity based on the estimated 
profitability of the FAIR Plan. As an element of the FAIR Plan Restructuring, the Company recognized an underwriting 
gain of $10,057 for the year ended December 31, 2024, through the release of prior and current years loss reserves. 
The Company’s private passenger automobile line of business prior year reserves decreased during the years 
ended December 31, 2024, 2023 and 2022 primarily due to improved retained private passenger results. The improved 
retained private passenger results were primarily due to fewer incurred but not yet reported claims than previously 
estimated and better than previously estimated severity on the Company’s established bodily injury and property damage 
case reserves. 
The following is information about incurred and paid claims development as of December 31, 2024, net of 
reinsurance, as well as cumulative claim frequency and the total of incurred-but-not-reported liabilities plus expected 
development on reported claims included within the net incurred claims amounts for our three largest lines of business. 
The cumulative number of reported claims include claims closed with payment, claims closed without payment and all 
open claims.  It does not include anticipated IBNR claims.  For the Private Passenger Automobile and Commercial 
Automobile lines of business, claim count is defined on a claimant basis where several claim counts may arise from a 
single auto accident.  For Homeowners and all other lines of business, claim count is defined on an accident basis. 
The information about incurred claims and allocated claim adjustment expense, net of reserves and paid 
ultimate claims development for the years ended December 31, 2015 to 2024 is presented as required supplementary 
information.

The Company believes that the positions taken on its income tax returns for open tax years will be sustained 
upon examination by the Internal Revenue Service.  Therefore, the Company has not recorded any liability for uncertain 

94 
tax positions under ASC 740, Income Taxes. 
During the years ended December 31, 2024 and 2023 there were no material changes to the amount of the 
Company’s unrecognized tax benefits or to any assumptions regarding the amount of its ASC 740 liability. 
As of December 31, 2024 and 2023, the Company had no unrecognized tax benefits, and none which if 
recognized would affect the effective tax rate. The Company does not currently anticipate significant changes in the 
amount of unrecognized income tax benefits during the next twelve months. 
The Company records interest and penalties associated with audits as a component of income before income 
taxes. Penalties are recorded in underwriting, operating and other expenses, and interest expense is recorded in interest 
expenses in the consolidated statements of operations. The Company had no interest and penalties related to income 
taxes accrued as of December 31, 2024 and 2023. 
 In the Company’s opinion, adequate tax liabilities have been established for all open years. However, the 
amount of these tax liabilities could be revised in the near term if estimates of the Company’s ultimate liability are 
revised. All tax years prior to 2021 are closed.

Share Repurchase Program 
On August 3, 2007, the Board approved a share repurchase program of up to $30,000 of the Company’s 
outstanding common shares.  The Board had cumulatively authorized increases to the existing share repurchase program 
of up to $200,000 of its outstanding common shares.  Under the program, the Company may repurchase shares of its 
common stock for cash in public or private transactions, in the open market or otherwise.  The timing of such 
repurchases and actual number of shares repurchased will depend on a variety of factors including price, market 
conditions and applicable regulatory and corporate requirements.  The program does not require the Company to 
repurchase any specific number of shares and it may be modified, suspended or terminated at any time without prior

Statutory Net Income and Surplus 
Statutory Accounting Practices 
The Company’s insurance company subsidiaries, domiciled in the Commonwealth of Massachusetts, prepare 
statutory financial statements in accordance with the accounting practices prescribed or permitted by the Division. 
Prescribed statutory accounting practices are those practices that are incorporated directly or by reference in state laws, 
regulations, and general administrative rules applicable to all insurance enterprises domiciled in a particular state. 
Permitted statutory accounting practices include practices not prescribed by the Division but allowed by the Division. 
For the year ended December 31, 2024, statutory net income was $43,387. Statutory net loss was $4,022 and statutory 
net income was $66,197 for the years ended December 31, 2023 and 2022, respectively. Statutory capital and surplus of 
the Company’s insurance subsidiaries was $758,789 and $744,904 at December 31, 2024 and 2023, respectively. 

95 
Dividends  
The 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 the Commonwealth of Massachusetts 
Commissioner of Insurance (the “Commissioner”). Massachusetts statute limits the dividends an insurer may pay in any 
twelve month period, without the prior permission of the Commissioner, to the greater of (i) 10% of the insurer’s surplus 
as of the preceding December 31 or (ii) the insurer’s net income for the twelve- month period ending the preceding 
December 31, in each case determined in accordance with statutory accounting practices. Our insurance company 
subsidiaries may not declare an “extraordinary dividend” (defined as any dividend or distribution that, together with 
other distributions made within the preceding twelve months, exceeds the limits established by Massachusetts statute) 
until thirty days after the Commissioner has received notice of the intended dividend and has not objected. As 
historically administered by the Commissioner, this provision requires the Commissioner’s prior approval of an 
extraordinary dividend. Under Massachusetts law, an insurer may pay cash dividends only from its unassigned funds, 
also known as earned surplus, and the insurer’s remaining surplus must be both reasonable in relation to its outstanding 
liabilities and adequate to its financial needs. At December 31, 2024, the statutory capital and surplus of Safety Insurance 
was $758,789 and its net income for 2024 was $43,387. As a result, a maximum of $75,879 is available in 2024 for such 
dividends without prior approval of the Commissioner. During the year ended December 31, 2024, Safety Insurance 
recorded dividends of $51,123. As result of this Massachusetts statute, the Insurance Subsidiaries had restricted net 
assets in the amount of $682,910 at December 31, 2024. 
Risk-Based Capital Requirements 
The NAIC has adopted a formula and model law to implement risk-based capital requirements for most 
property and casualty insurance companies, which are designed to determine minimum capital requirements and to raise 
the level of protection that statutory surplus provides for policyholder obligations. Under Massachusetts law, insurers 
having less total adjusted capital than that required by the risk-based capital calculation will be subject to varying 
degrees of regulatory action, depending on the level of capital inadequacy. The risk-based capital law provides for four 
levels of regulatory action. The extent of regulatory intervention and action increases as the level of total adjusted capital 
to risk-based capital falls. As of December 31, 2024, the Insurance Subsidiaries had total adjusted capital of $758,789, 
which is in excess of amounts requiring company or regulatory action at any prescribed risk-based capital action level. 
Minimum statutory capital and surplus, or company action level risk-based capital, was $236,219 at December 31, 2024. 
16. 
Fair Value of Financial Instruments 
ASC 820, Fair Value Measurements and Disclosure provides a revised definition of fair value, establishes a 
framework for measuring fair value and expands financial statement disclosure requirements for fair value 
information.  Under ASC 820, fair value is defined as the price that would be received to sell an asset or paid to transfer 
a liability in an orderly transaction between market participants (an exit price).  ASC 820 establishes a fair value 
hierarchy that distinguishes between inputs based on market data from independent sources (“observable inputs”) and a 
reporting entity’s internal assumptions based upon the best information available when external market data is limited or 
unavailable (“unobservable inputs”).  The fair value hierarchy in ASC 820 prioritizes fair value measurements into three 
levels based on the nature of the inputs as follows: 
Level 1 — Valuations based on quoted prices in active markets for identical assets and liabilities; 
Level 2 — Valuations based on observable inputs that do not meet the criteria for Level 1, including quoted 
prices in inactive markets and quoted prices in active markets for similar, but not identical instruments; and 
Level 3 — Valuations based on unobservable inputs. 
Fair values for the Company’s fixed maturity securities are based on prices provided by its custodian bank and 
its investment managers.  Both the Company’s custodian bank and investment managers use a variety of independent, 
nationally recognized pricing services to determine market valuations.  If the pricing service cannot provide fair value 

96 
determinations, the Company obtains non-binding price quotes from broker-dealers.  A minimum of two quoted prices is 
obtained for the majority of the Company’s available-for-sale fixed maturity securities in its investment portfolio.  The 
Company uses a third-party pricing service as its primary provider of quoted prices from third-party pricing services and 
broker-dealers.  To provide reasonable assurance of the validity of each price or quote, a secondary third-party pricing 
service or broker-dealer quote is obtained from the Company’s custodian or investment managers.  An examination of 
the pricing data is then performed for each security.  If the variance between the primary and secondary price quotes for 
a security is within an accepted tolerance level, the quoted price obtained from the Company’s primary source is used for 
the security.  If the variance between the primary and secondary price quotes exceeds an accepted tolerance level, the 
Company obtains a quote from an alternative source, if possible, and documents and resolves any differences between 
the pricing sources.  In addition, the Company may request that its investment managers and its traders provide input as 
to which vendor is providing prices that its traders believe are reflective of fair value for the security.  Following this 
process, the Company may decide to value the security in its financial statements using the secondary or alternative 
source if it believes that pricing is more reflective of the security’s value than the primary pricing provided by its 
custodian bank.  The Company analyzes market valuations received to verify reasonableness, to understand the key 
assumptions used and their sources, and to determine an appropriate ASC 820 fair value hierarchy level based upon 
trading activity and the observability of market inputs.  Based on this evaluation and investment class analysis, each 
price is classified into Level 1, 2 or 3. 
Fair values of instruments are based on (i) quoted prices in active markets for identical assets (Level 1), 
(ii) quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets 
that are not active and model-derived valuations in which all significant inputs are observable in active markets (Level 2) 
or (iii) valuations derived from valuation techniques in which one or more significant inputs are unobservable in the 
marketplace (Level 3). 
The Company’s Level 1 securities consist of equity securities whose values are based on quoted prices in active 
markets for identical assets.  The Company’s Level 2 securities are comprised of available-for-sale fixed maturity 
securities whose fair value was determined using observable market inputs.  The Company’s Level 3 security consists of 
an investment in the Federal Home Loan Bank of Boston related to Safety Insurance Company’s membership stock, 
which is not redeemable in a short-term time frame.  Fair values for securities for which quoted market prices were 
unavailable were estimated based upon reference to observable inputs such as benchmark interest rates, market 
comparables, and other relevant inputs.  Investments valued using these inputs include U.S. Treasury securities, 
obligations of states and political subdivisions, corporate and other securities, commercial and residential mortgage-
backed securities, and other asset-backed securities.  Inputs into the fair value application that are utilized by asset class 
include but are not limited to: 

Obligations of states and political subdivisions:  overall credit quality, including assessments of market 
sectors and the level and variability of sources of payment such as general obligation, revenue or lease; 
credit support such as insurance, state or local economic and political base, prefunded and escrowed to 
maturity covenants. 

Corporate and other securities: overall credit quality, the establishment of a risk adjusted credit spread 
over the applicable risk-free yield curve for discounted cash flow valuations; assessments of the level of 
industry economic sensitivity, company financial policies, indenture restrictive covenants, and/or security 
and collateral. 

Residential mortgage-backed securities: U.S. agency pass-throughs, collateralized mortgage obligations 
(“CMOs”), non U.S. agency CMOs:  estimates of prepayment speeds based upon historical prepayment rate 
trends, underlying collateral interest rates, original weighted average maturity, vintage year, borrower 
credit quality characteristics, interest rate and yield curve forecasts, U.S. government support programs, tax 
policies, and delinquency/default trends. 

Commercial mortgage-backed securities:  overall credit quality, including assessments of the level and 
variability of credit support and collateral type such as office, retail, or lodging, predictability of cash flows 
for the deal structure, prevailing economic market conditions. 

97 

Other asset-backed securities:  overall credit quality, estimates of prepayment speeds based upon historical 
trends and characteristics of underlying loans, including assessments of the level and variability of 
collateral, revenue generating agreements, area licenses agreements, product sourcing agreements and 
equipment and property leases. 

FHLB-Boston: value is equal to the cost of the member stock purchased. 
In order to ensure the fair value determination is representative of an exit price (consistent with ASC 820), the 
Company’s procedures for validating quotes or prices obtained from third parties include, but are not limited to, 
obtaining a minimum of two price quotes for each fixed maturity security if possible, as discussed above, the periodic 
testing of sales activity to determine if there are any significant differences between the market price used to value the 
security as of the balance sheet date and the sales price of the security for sales that occurred around the balance sheet 
date, and the periodic review of reports provided by its external investment manager regarding those securities with 
ratings changes and securities placed on its “Watch List.” In addition, valuation techniques utilized by pricing services 
and prices obtained from external sources are reviewed by the Company’s external investment manager, whose 
investment professionals are familiar with the securities being priced and the markets in which they trade, to ensure the 
fair value determination is representative of an exit price. 
All unadjusted estimates of fair value for our fixed maturities priced by the pricing services as described above 
are included in the amounts disclosed in Level 2.  With the exception of the FHLB-Boston security, which is categorized 
as a Level 3 security, the Company’s entire portfolio was priced based upon quoted market prices or other observable 
inputs as of December 31, 2024. There were no significant changes to the valuation process during the year ended 
December 31, 2024. As of December 31, 2024 and 2023, no quotes or prices obtained were adjusted by management. All 
broker quotes obtained were non-binding. 
At December 31, 2024 and 2023, investments in fixed maturities classified as available-for-sale had a fair value 
which equaled carrying value of $1,115,218 and $1,052,145, respectively. At December 31, 2024, short-term 
investments had a fair value of $19,975. The Company held no short-term investments during the year ended December 
31, 2023.  The carrying values of cash and cash equivalents and investment income accrued approximated fair value. 
The following tables summarize the Company’s total fair value measurements for investments for the periods 
indicated.

Transfers in and out of Level 3 are attributable to changes in the ability to observe significant inputs in 
determining fair value exit pricing.  As noted in the table above, no transfers were made in or out of Level 3 during 2024, 
2023 and 2022.  The Company held one Level 3 security at December 31, 2024. 
As of December 31, 2024 and 2023, there were approximately $31,754 and $33,173 in a REIT and is included 
in equity securities in the consolidated balance sheets.  The REIT is excluded from the fair value hierarchy because the 
fair value is recorded using the net asset value per share practical expedient.  The net asset value per share of this REIT is 
derived from member ownership in the capital venture to which a proportionate share of independently appraised net 
assets is attributed.  The fair value was determined using the trust’s net asset value obtained from its audited financial 
statements.  The Company is required to submit a request 45 days before a quarter end to dispose of the security.
