PART I.

ITEM 1.    BUSINESS

General

We are a leading provider of private passenger automobile insurance in Massachusetts.  In addition to private passenger automobile insurance (which represented 59.6% of our direct written premiums in 2015), we offer a portfolio of property and casualty insurance products, including commercial automobile, homeowners, dwelling fire, umbrella and business owner policies.  Operating exclusively in Massachusetts and New Hampshire through our insurance company subsidiaries, Safety Insurance Company ("Safety Insurance"), Safety Indemnity Insurance Company ("Safety Indemnity") and Safety Property and Casualty Insurance Company ("Safety P&C") (together referred to as the "Insurance Subsidiaries"), we have established strong relationships with independent insurance agents, who numbered 924 in 1,102 locations throughout Massachusetts and New Hampshire during 2015.  We have used these relationships and our extensive knowledge of the Massachusetts market to become the third largest private passenger automobile carrier, capturing an approximate 10.2% share of the Massachusetts private passenger automobile insurance market, and  the second largest commercial automobile carrier, with an 14.1% share of the Massachusetts commercial automobile insurance market in 2015 according to statistics compiled by Commonwealth Automobile Reinsurers ("CAR").  We are also the fourth largest homeowners insurance carrier in Massachusetts with a 7.2% share of the Massachusetts homeowners insurance market.  In addition, we were also ranked the 45th largest automobile writer in the country according to A.M. Best, based on 2014 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 private passenger automobile and homeowners insurance in New Hampshire during 2008, personal umbrella insurance during 2009, and commercial automobile insurance during 2011.  During the years ended December 31, 2015, 2014, and 2013, the Company wrote $22,731, $18,755, and $13,773 in direct written premiums, respectively, and approximately 24,364, 20,626 and 15,580 policies, respectively, in New Hampshire.

On February 9, 2015, the Insurance Subsidiaries each received a license to begin writing our property and casualty insurance products in the state of Maine. We anticipate that we will begin to write new business in Maine beginning in the first quarter of 2016.

Our Competitive Strengths

We Have Strong Relationships with Independent Agents.  In 2015, Independent agents accounted for approximately 63.4% of the Massachusetts automobile insurance market measured by direct written premiums as

compared to approximately 31.3%  nationwide, based on data made available by A.M. Best. For that reason, our strategy is centered around, and we sell exclusively through, a network of independent agents, who numbered 924 in 1,102 locations throughout Massachusetts and New Hampshire during 2015.  In order to support our independent agents and enhance our relationships with them, we:

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 and New Hampshire.  We must compete with other insurance carriers for the business of independent agents.

We Have a History of Profitable Operations.  In 34 out of 35 years since our inception in 1979, we have been profitable.  The lone year where we did not have profits was 2015 when we were impacted by claims related to the highest recorded snowfall totals in Massachusetts history.  We have achieved our profitability, among other things, by:

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

We Have an Experienced, Committed and Knowledgeable Management Team.  Our senior management team owns approximately 4.9% of the common stock of Safety Insurance Group, Inc. on a fully diluted basis.  Our senior management team has an average of over 29 years of experience with Safety.  The team has demonstrated an ability to operate successfully within the Massachusetts automobile and homeowner insurance markets.

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:

Property and Casualty Insurance Market

Introduction.  We are licensed by the Commissioner of Insurance (the "Commissioner") to transact property and casualty insurance in Massachusetts.  All of our Massachusetts business is extensively regulated by the Commissioner.

The Massachusetts Market for Private Passenger Automobile Insurance.  Private passenger automobile insurance is generally considered to be more heavily regulated in Massachusetts than in other states, under what the Massachusetts Commissioner of Insurance calls Managed Competition.  Since 2008, Massachusetts automobile insurance premium rates are strictly regulated under a prior approval rate review process, governed by regulations that set certain terms and conditions that insurers must comply with in establishing their rates.    Certain of the historically unique factors in Massachusetts continue to exist, including compulsory insurance, affinity group marketing, and the prominence of independent agents.

Products

Historically, we have focused on underwriting private passenger automobile insurance, which is written through our subsidiary, Safety Insurance.  In 1989, we formed Safety Indemnity to offer commercial automobile insurance at preferred rates.  Since 1997, we have expanded the breadth of our product line in order for agents to address a greater portion of their clients' insurance needs by selling multiple products. Homeowners, business owners’ policies, personal umbrella, dwelling fire and commercial umbrella insurance are written by Safety Insurance at standard rates, and written by Safety Indemnity at preferred rates.  In December 2006, we formed Safety P&C to offer homeowners and commercial automobile insurance at ultra preferred rates.

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

Our product lines are as follows:

Private Passenger Automobile (59.6% of 2015 direct written premiums).  Private passenger automobile insurance is our primary product, and we support all Massachusetts policy forms and limits of coverage.  Private passenger automobile 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.  We have priced our private passenger coverage competitively by offering group discounts since 1995 and we currently offer approximately 95 affinity group discount programs ranging from 3.0% to 8.0% discounts.  Under Massachusetts' Managed Competition regulations, we offer various new discounts including a discount of up to 10.0% when a private passenger policy is issued along with an other than private passenger policy with us, a longevity/renewal credit of up to 4.0% for policyholders who maintain continuous coverage with us, and up to a 7.0% e-Customer discount for policyholders who want electronic policy issuance with one combined bill for all of their policies with us.  We filed and were approved for a Massachusetts private passenger automobile insurance rate increase of 3.8% effective June 1, 2015.    We filed and were approved for a New Hampshire private passenger automobile rate increase of 5.0%, which was effective November 1, 2015.

Commercial Automobile (13.8% of 2015 direct written premiums).  Our commercial automobile program supports all Massachusetts policy forms and limits of coverage including endorsements that broaden coverage over and above that offered on the standard Massachusetts policy forms.  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, and insure individual vehicles as well as commercial fleets.  Commercial automobile policies are written at a standard rate through Safety Insurance.  We filed and were approved for a Massachusetts commercial automobile insurance rate increase of 3.5% effective February 1, 2015.  We filed and were approved for a New Hampshire commercial automobile insurance rate increase of 7.9% effective August 1, 2015. Qualifying risks eligible for preferred rates are written through Safety Indemnity which offers rates that are 20.0% lower than Safety Insurance.  Qualifying risks eligible for ultra preferred rates are written through Safety P&C which offers rates that are 35.0% lower than Safety Insurance.

Homeowners (21.7% of 2015 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.  We offer loss-free credits of up to 16.0% for eight years of loss-free experience, an account credit of up to 20.0% when a home is written together with an automobile, and up to a 5.0% e-Customer discount for policyholders who want electronic policy issuance with one combined bill for all of their policies with us.  We filed and were approved for a Massachusetts rate increase of 9.1% which was effective November 1, 2015. We filed and were approved for a New Hampshire homeowners rate increase of 7.9%, which was effective November 1, 2015. All forms of homeowners coverage are written at a standard rate through Safety Insurance.  Qualifying risks eligible for

preferred rates are written through Safety Indemnity which offers rates that are 13.0% lower than Safety Insurance.  Homes with high insured property values are written through Safety P&C. 

Business Owners Policies (2.8% of 2015 direct written premiums).  We serve eligible small and medium sized commercial accounts with a program that covers apartments and residential condominiums; mercantile establishments, including limited cooking restaurants; offices, including office condominiums; processing and services businesses; special trade contractors; and wholesaling businesses.  Business owner policies provide liability and property coverage for many perils, including business interruption from a covered loss.  Equipment breakdown coverage is automatically included, and a wide range of additional coverage is available to qualified customers.  We write policies for business owners at standard rates with qualifying risks eligible for preferred lower rates.

Commercial Package Policies (Included in our Business Owners Policies direct written premiums).  For larger commercial accounts or those clients that require more specialized or tailored coverages, we offer a commercial package policy program that covers a more extensive range of business enterprises.  Commercial package policies provide any combination of property, general liability, crime and inland marine insurance.  Property automatically includes equipment breakdown coverage, and a wide range of additional coverage is available to qualified customers.  We write commercial package policies at standard rates with qualifying risks eligible for preferred lower rates.

Personal Umbrella (0.9% of 2015 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 offer an account credit of 10.0% when an umbrella policy is written together with an automobile insurance policy.  We write policies at standard rates with limits of $1,000 to $5,000.

Dwelling Fire (1.1% of 2015 direct written premiums).  We underwrite dwelling fire insurance, which is a limited form of a homeowner's policy for non-owner occupied residences.  We offer superior construction and protective device credits, with an account credit of 5.0% when a dwelling fire policy is issued along with an automobile policy.  We write all forms of dwelling fire coverage at standard rates with qualifying risks eligible for preferred lower rates.

Commercial Umbrella (0.1% of 2015 direct written premiums).  We offer an excess liability product to clients for whom we underwrite both commercial automobile and business owner policies.  The program is directed at commercial automobile risks with private passenger-type automobiles or light and medium trucks.  We write commercial umbrella policies at standard rates with limits ranging from $1,000 to $5,000.

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

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

In the wake of the September 11, 2001 tragedies, the insurance industry is also impacted by terrorism, and we have filed and received approval for a number of terrorism endorsements from the Commissioner, which limit our liability and property exposure according to the Terrorism Risk Insurance Act of 2002, the Terrorism Risk Insurance Extension Act of 2005, the Terrorism Risk Insurance Program Reauthorization Act of 2007 and the Terrorism Risk Insurance Program Reauthorization of 2014.  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 Limited 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 under Massachusetts law to cancel any coverage, other than private passenger automobile insurance, within the first 30 days after it is bound.  In total, our independent agents numbered 924 and had 1,102 offices (some agencies have more than one office) and approximately 8,118 customer service representatives during 2015.

Voluntary Agents.  In 2015, we obtained approximately 93.2% of our direct written premiums for automobile insurance and 100% of our direct written premiums for all of our other lines of business through our voluntary agents.  As of December 31, 2015, we had agreements with 749 voluntary agents.  Our voluntary agents are located in all regions of Massachusetts and New Hampshire.

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 performance of our agents during the prior year.  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 premiums.  No individual agency generated more than 5.0% of our direct written premiums in 2015.

Massachusetts law guarantees that CAR provides motor vehicle insurance coverage to all qualified applicants.  Under 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 servicing 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 a Limited Servicing Carrier Program ("LSC"). CAR has approved Safety and three other servicing carriers to process ceded commercial automobile insurance.  Approximately $140,000 of ceded premium is spread equitably among the four servicing carriers.  Subject to the Commissioner's review, 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.

CAR also runs a reinsurance pool for Taxi, Limousine and Car Service risks (the "Taxi/Limo Program").  CAR approved Safety as one of the two servicing carriers for this program beginning January 1, 2011 for a five-year term.  Approximately $10,000 of ceded premium was spread equitably between the two servicing carriers.

We are assigned independent agents by CAR who can submit commercial business to us in the LSC and Taxi/Limo Program, and we classify those agents as commercial LSC producers. 

The table below shows our direct written exposures in each of our product lines for the periods indicated and the change in exposures for each product line.

Our total written exposures increased by 0.1% for the year ended December 31, 2015.   Our commercial automobile exposures increased by 5.8% in 2015 due to additional exposures from voluntary agents. Our other than auto exposures increased by 2.6% in 2015 primarily as a result of our voluntary agents' efforts to sell multiple products to their clients and our pricing strategy of offering account discounts to policyholders who insure both their home and automobile with us.  In 2015, 55.8% of the private passenger automobile exposures we insure had an other than private passenger policy with us, compared to 55.4% and 52.4% in 2014 and 2013, respectively.  In addition, 81.8% of our homeowners’ policyholders had a matching automobile policy with us in 2015 compared to 83.2% in 2014 and 83.6% in 2013.

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 and New Hampshire 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:

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

Commission Schedule and Profit Sharing Plan.  We have several programs designed to attract profitable new business from agents by paying them competitive commissions. We recognize our top performing agents by making them members of either our Chairman's Elite, Chairman's, President's, Executive's or Preferred Agent's Club.  In 2015, members of these Clubs received a commission of up to 18.0% of premiums for each new private passenger auto policy, up to 22.0% of premiums for each new homeowner policy, up to 20.0% for each new commercial auto policy and up to 22.0% for each new commercial property policy.

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

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

Underwriting

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

Pricing.  Subject to the Commissioner's review, we set rates for our private passenger business using industry loss cost data, our own loss experience, residual market deficits, catastrophe modeling and prices charged by our competitors in the Massachusetts market.  Additionally subject to the Commissioner's review, Commonwealth Automobile Reinsurers (“CAR”) establishes the rates for personal automobile policies assigned to carriers through the Massachusetts Automobile Insurance Plan (“MAIP”).  In accordance with Massachusetts law, insurers may only charge MAIP policyholders the lower of the CAR/MAIP rate or the company's competitive voluntary market rate.  We offer group discounts to private passenger auto policyholder who are members of 95 affinity groups.  In general, we target affinity groups with a mature and stable membership base along with favorable driving records, offering between a 3.0% and 8.0% discount (with 4.7% being the average discount offered).

Subject to the Commissioner's review, CAR sets the premium rates for commercial automobile policies reinsured through the CAR residual market pool.  We set rates for voluntary commercial automobile policies that are not reinsured through CAR, and for all other insurance lines we offer, including homeowners, dwelling fire, personal umbrella, commercial umbrella, commercial package policies and business owner policies.  All of these rates are subject to the approval of the Commissioner of Insurance.  In each line of business, we base our rates on our own loss experience, residual market deficits, catastrophe modeling, industry loss cost data and prices charged by our competitors in the Massachusetts market.  We have three pricing segments for most products, utilizing Safety Insurance for standard rates, Safety Indemnity for preferred rates and Safety Property and Casualty for ultra preferred rates.

CAR Reinsurance Pool.  CAR operates a reinsurance pool for commercial automobile policies and we are one of four approved servicing carriers.  CAR also operates a reinsurance pool for taxi/limousine/car service commercial automobile policies, and we are one of two servicing carriers that service these policies for CAR.  All commercial automobile business and taxi/limousine/car service business that is not written in the voluntary market in Massachusetts is apportioned to one of these servicing carriers who handle that business on behalf of CAR.  Every Massachusetts commercial automobile insurer must bear a portion of the losses of the total commercial reinsurance pool that is serviced by the approved servicing carriers.

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.  Among other things, we usually require that the private passenger portion of the portfolio have a pure loss ratio of 65.0% or less on the portion of the agent's portfolio that we would underwrite.  In addition, we require any new voluntary agent to commit to transfer a portfolio to us consisting of at least 300 policies.

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

In personal lines, our agents now submit approximately 99% of all applications for new policies or endorsements for existing policies through Safety Express.

Our rate pursuit team aggressively monitors all insurance transactions to make sure we receive the correct premium for the risk insured.  We accomplish this by verifying pricing criteria, such as proper classification of drivers, the make, model, and age of insured vehicles, and the availability of discounts.  We verify that operators are properly listed and classified, assignment of operators to vehicles, vehicle garaging, vehicle pre-inspection requirements, and in some cases the validity of discounts.  In our homeowners and dwelling fire lines, our team has completed a project to update the replacement costs for each dwelling.  We use third-party software to assist in these appraisal efforts.

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

Legal and Regulatory Compliance.  The Legal and Regulatory Compliance department provides general legal and compliance support to all business units within the company.  The department monitors legal and regulatory changes affecting the company and provides guidance on how to comply with those changes.  The department reviews business unit operations to identify and address compliance vulnerabilities.  It serves as the primary liaison for company regulators on regulatory matters, including complaints, inquiries, data requests and the like.  The department also provides general legal support to all areas of the company, including the review of contracts and legal agreements with vendors and consultants. Legal and Regulatory Compliance additionally is responsible for the rate and form filing function at the company, across all states and lines of business.

Technology

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

We believe that our technology initiatives have increased revenue and decreased costs.  For example, these initiatives have allowed us to reduce the number of call-center transactions which we perform, and to transfer many manual processing functions from our internal operations to our independent agents.  We also believe that these initiatives have contributed to overall increases in productivity.

Internal Applications (Intranet)

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

Claims.  Our claims workload management application allows our claims and subrogation adjusters to better manage injury claims.  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 casualty claims, which we believe helps reduce the total amount of our claims expense.

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

The RadicalGlass.com application allows our claims department to contain glass costs by increasing the windshield repair to replacement ratio.  For every windshield that is repaired rather than replaced there is an average savings of approximately $316 per windshield claim.

Our first VIP Claims Center was introduced during 2006 to provide increased service levels to our independent insurance agents and their clients.  We currently operate three VIP Claims Centers which use a network of rental car centers and auto body repair shops to provide a higher level of service to the clients of the independent insurance agents while reducing costs, such as rental expense, through reduced cycle times.

Billing.  Proprietary billing systems, integrated with the systems of our print and lock-box vendors, expedite the processing and collection of premium receipts and finance charges from agents and policyholders.  We believe the sophistication of our direct bill system helps us to limit our bad debt expense.  Our bad debt expense as a percentage of direct written premiums was 0.1% in both 2015 and 2014.

External Applications

Our Agent Technology offerings are centralized within our agency portal and feature PowerDesk and Safety Express.  PowerDesk is a web based application that allows for billing inquiry, agent payments on behalf of their policyholders, policy inquiry and claims inquiry.  Safety Express provides agents with new business and endorsement entry, real time policy issuance for personal lines, immediate printing of declarations pages in agents' offices, policy

downloads to most major agency management systems and data imports from Boston Software's WinRater (Massachusetts) and Vertafore's PL Rater (New Hampshire). In addition, we provide our agents with commission and claims download for all lines of business, Transformation Station and Transact Now Inquires, e-Claims online claims reporting, e-View daily transaction reports and e-Docs online electronic document file cabinet. 

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

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

Claims

Because of the unique differences between the management of casualty claims and property claims, we use separate departments for each of these types of claims.

Casualty Claims

We have adopted stringent claims settlement procedures, which include guidelines that establish settlement ranges for soft tissue injuries, which constituted approximately 70% of our bodily injury claims in 2015.  If we are unable to settle these claims within our pricing guidelines, we explore other cost effective options including alternative disputes 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 are able to report claims directly by phone, web or mobile application.  In addition, we utilize an after- hours reporting vendor to ensure that new claims can be reported 24 hours per day and 365 days per year.

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

We believe the structure of our casualty claims unit allows us to respond quickly to claimants anywhere in Massachusetts and New Hampshire.  Comprising 120 people, the department is organized into distinct claim units that contain loss costs on injury claims.  Field adjusters are located geographically for prompt response to claims, with our litigation unit focused on managing loss costs and litigation expenses for serious injury claims.

Additionally, we utilize a special unit to investigate fraud in connection with casualty claims.  This special unit has seven dedicated employees including five field investigators.  In cases where adjusters suspect fraud in connection with a claim, we deploy this special unit to conduct investigations.  We deny payment to claimants in cases in which we have succeeded in accumulating sufficient evidence of fraud.

Property Claims

Our property claims unit handles property claims arising in our private passenger and commercial automobile, homeowners and other insurance lines.  Process automation has streamlined our property claims function.  Many of our property claims are now handled by our agents through AVC using our Power Desk software application.  As agents receive calls from claimants, Power Desk permits the agent to immediately send information related to the claim directly to us and to an independent appraiser selected by the agent to value the claim.  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.  We benefit from decreased labor expenses from the need for fewer employees to handle the reduced property claims call volume.

Another important factor in keeping our overall property claims costs low is collecting subrogation recoveries.  We track the amounts we pay out in claims costs and identify cases in which we believe we can reclaim some or all of those costs through the use of our automated workload management tools.

Reserves

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

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

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

When reviewing reserves, we analyze historical data and estimate the impact of various loss development factors, such as our historical loss experience and that of the industry, legislative enactments, judicial decisions, legal developments in imposition of damages, and changes and trends in general economic conditions, including the effects of inflation.  There is no precise method, however, for evaluating the impact of any specific factor on the adequacy of reserves, because the eventual development of reserves is affected by many factors.  After taking into account all relevant factors, management believes that our provision for unpaid losses and loss adjustment expenses at December 31, 2015 is adequate to cover the ultimate net cost of losses and claims incurred as of that date.

Management determines its loss and loss adjustment expense ("LAE") reserves 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 $446,368 to a high of $495,541 as of December 31, 2015.  The Company's net loss and LAE reserves, based on our actuaries' best estimate, were set at $485,716 as of December 31, 2015.  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, 2015.

At the end of each period, the reserves were re-estimated for all prior accident years. Our prior year reserves decreased by $30,313, $37,368, and $28,889 for the years ended 2015, 2014, and 2013, respectively. The decreases in prior year reserves in 2015 resulted from re-estimations of prior year’s ultimate loss and LAE liabilities and are primarily composed of reductions of $18,644 in our retained automobile reserves and $7,964 in our retained homeowner’s reserves.  The decreases in prior year reserves in 2014 resulted from re-estimations of prior year’s ultimate loss and LAE liabilities and is primarily composed of reductions of $23,272 in our retained automobile reserves and $8,804 in our retained homeowner reserves. The decrease in prior year reserves during 2013 is primarily composed of reductions of $23,938 in our retained automobile reserves and $4,740 in our retained homeowners reserves. It is not appropriate to extrapolate future favorable or unfavorable development of reserves from this past experience.

Our private passenger automobile line of business prior year reserves decreased by $14,411 for the year ended December 31, 2015, primarily due to improved retained private passenger results of $12,716 for  the accident years 2009 through 2013. Our private passenger automobile line of business prior year reserves decreased by $20,815 for the year ended December 31, 2014, primarily due to improved retained private passenger results of $17,789 for accident years 2007 through 2012. Our private passenger automobile line of business reserves decreased by $21,090 for the year ended December 31, 2013, primarily due to improved retained private passenger results of $18,116 for accident years 2007 through 2012.  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. Our homeowners line of business prior year reserves decreased by $7,255 for the year ended December 31, 2015, primarily due to improved retained homeowner results of $7,354 for the years 2010 through 2013.

The following table represents the development of reserves, net of reinsurance, for calendar years 2005 through 2015.  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, 2015.

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 2012 estimate for a previously incurred loss was $150 and the loss was reserved at $100 in 2008, the $50 deficiency (later estimate minus original estimate) would be included in the cumulative (redundancy) deficiency in each of the years 2008-2012 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.

As the table shows, our net reserves grew at a faster rate than our gross reserves over the ten-year period.  As we have grown, we have been able to retain a greater percentage of our direct business.  Additionally, in the past we conducted substantial business as a servicing carrier for other insurers, in which we would service the residual market automobile insurance business assigned to other carriers for a fee.  All business generated through this program was ceded to the other carriers.  As we reduced the amount of our servicing carrier business, our proportion of reinsurance ceded diminished.

The table also shows that we have substantially benefited in the current and prior years from releasing redundant reserves.  In the years ended December 31, 2015, 2014, and 2013 we decreased loss reserves related to prior years by $30,313, $37,368 and $28,889, 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 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.  Swiss Re, our primary reinsurer, maintains an A.M. Best rating of "A+" (Excellent). Most of our other reinsurers have an A.M. Best rating of “A+” (Excellent) or “A” (Excellent).

We maintain reinsurance coverage to help lessen the effect of losses from catastrophic events, maintaining coverage that during 2015 protected us in the event of a "115-year storm" (that is, a storm of a severity expected to occur once in a 115-year period).  We use various software products to measure our exposure to catastrophe losses and the probable maximum loss to us for catastrophe losses such as hurricanes.  The models include estimates for our share of the catastrophe losses generated in the residual market for property insurance by the Massachusetts Property Insurance Underwriting Association ("FAIR Plan").  In 2015, we purchased three layers of excess catastrophe reinsurance providing $515,000 of coverage for property losses in excess of $50,000 up to a maximum of $565,000.  Our reinsurers’ co-participation is 65.0% of $100,000 for the 1st layer, 80.0% of $280,000 for the 2nd layer, and 80.0% of $135,000 for the 3rd layer.

For 2016, we have increased our reinsurance coverage by buying a 4th layer at the top end of the reinsuance program.  We purchased four layers of excess catastrophe reinsurance providing $615,000 of coverage for property losses in excess of $50,000 up to a maximum of $665,000.  Our reinsurers’ co-participation is 65.0% of $100,000 for the 1st layer, 80.0% of $280,000 for the 2nd layer, 80.0% of $135,000 for the 3rd layer and 80% of $100,000 for the 4th layer. As a result of the changes to the models, and our revised reinsurance program, our catastrophe reinsurance in 2016 protects us in the event of a “133-year storm” (that is, a storm of a severity expected to occur once in a 133-year period). 

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

In the wake of the September 11, 2001 tragedies, reinsurers began to exclude coverage for claims in connection with any act of terrorism.  Our reinsurance program excludes coverage for acts of terrorism, except for fire or collapse losses as a result of terrorism, under homeowners, dwelling fire, private passenger automobile and commercial automobile policies.

The Terrorism Risk Insurance Act of 2002 ("TRIA") was signed into law on November 26, 2002, and expired December 31, 2005.  The Terrorism Risk Insurance Extension Act of 2005 was signed into law on December 22, 2005, and expired December 31, 2007.  The Terrorism Risk Insurance Extension Act of 2007 ("TRIEA") was signed into law on December 26, 2007 which reauthorized TRIA for seven years, expanded the definition of an "Act of Terrorism" while expanding the private sector role and reducing the federal share of compensation for insured losses under the program.  TRIA expired on December 31, 2014, but on January 12, 2015 Congress reauthorized TRIA retroactive to January 1, 2015 with the program now lasting through 2020.  The intent of this legislation is to provide federal assistance to the insurance industry for the needs of commercial insurance policyholders with the potential exposure for losses due to acts of terrorism.  The TRIEA provides reinsurance for certified acts of terrorism.

In addition to the above mentioned reinsurance programs and as described in more detail above under The Massachusetts Property and Casualty Insurance Market, we are a participant in CAR, a state-established body that runs the residual market reinsurance programs for commercial automobile insurance in Massachusetts under which premiums, expenses, losses and loss adjustment expenses on ceded business are shared by all insurers writing automobile insurance in Massachusetts.  We also participate in the FAIR Plan in which premiums, expenses, losses and loss adjustment expenses on homeowners business that cannot be placed in the voluntary market are shared by all insurers writing homeowners insurance in Massachusetts.  The FAIR Plan’s exposure to catastrophe losses increased and as a result, the FAIR Plan decided to buy reinsurance to reduce their exposure to catastrophe losses.  On July 1, 2015, the FAIR Plan purchased $1,325,000 of catastrophe reinsurance for property losses with retention of $100,000. 

For the year ended December 31, 2015, our total expected reinsurance recovery from reinsurers under our catastrophe reinsurance program related to the 2015 snow event as discussed in the Recent Trends and Event section is $67,934.  Amounts recoverable from reinsurers are billed to the reinsurer as claims are paid by the Company.  At December 31, 2015, the reinsurance recoverable on paid and unpaid loss and loss adjustment expenses related to the 2015 snow event is $39,553. 

On December 15, 2015, the Company filed for arbitration with a reinsurer in regards to the reinsurance recoverable resulting from the 2015 winter storm losses that are admissible under our contract.  The total amount of recoverable in dispute, which is based on our total incurred loss, is $22,838.  No provision for collectability has been recorded in the financial statements as we believe the recoverable is valid and will be recovered.

At December 31, 2015, we also had $70,812 due from CAR comprising of loss and loss adjustment expense reserves, unearned premiums and reinsurance recoverables.

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

Competition

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

than we are have chosen not to compete in a material way in the Massachusetts private passenger automobile market, if one or more of these companies decided to aggressively enter the market it could have a material adverse effect on us.  The Commissioner announced that Managed Competition reforms were, in part, designed to make Massachusetts more appealing to these companies.  Since then, new companies have entered the market including Progressive Insurance Company, Peerless  and Safeco (subsidiaries of Liberty Mutual), AIG, Vermont Mutual, Preferred Mutual, IDS, Occidental, GEICO, Harleysville, Foremost and Allstate (including their subsidiary Esurance).  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.

Our principal competitors within the Massachusetts private passenger automobile insurance market are  Commerce Insurance Company, Liberty Mutual (including Peerless) and Arbella Insurance Group, which held 25.7%, 11.5% and 10.0% market shares based on automobile exposures, respectively, in 2015 according to CAR.

Employees

At December 31, 2015, we employed 622 employees.  Our employees are not covered by any collective bargaining agreement.  Management considers our relationship with our employees to be good.

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, 2015, 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. We have no exposure to European sovereign debt.

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).  This one issuer must be rated "A" or above by Moody's.  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 10.0% of our portfolio invested in senior bank loans and high yield bonds at December 31, 2015, 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.  Since 1986, we have utilized the services of a third-party investment manager.

The following table reflects the composition of our investment portfolio as of December 31, 2015 and 2014.

(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 interests in mutual funds held to fund the Company's executive deferred compensation plan.

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 typically are 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 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.

The following table reflects our investment results for each year in the three-year period ended December 31, 2015.

(1) After investment expenses, excluding realized investment gains or losses.

(2) Net investment income for the period divided by average invested securities and cash for the same period.

As of December 31, 2015, 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, senior bank loans and high yield bonds. We have no exposure to European sovereign debt.

The composition of our fixed income security portfolio by Moody's rating is presented in the following table.

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.

Moody's rating system utilizes nine symbols to indicate the relative investment quality of a rated bond. “Aaa” rated bonds are judged to be of the best quality and are considered to carry the smallest degree of investment risk. “Aa” rated bonds are also judged to be of high quality by all standards. Together with “Aaa” bonds, these bonds comprise what are generally known as high grade bonds. Bonds rated “A” possess many favorable investment attributes and are considered to be upper medium grade obligations. “Baa” rated bonds are considered as medium grade obligations; they are neither highly protected nor poorly secured. Bonds rated “Ba” or lower (those rated “B”, “Caa”,  “C” and “D”) are considered to be too speculative to be of investment quality.

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, 2015, 79.4% of our available for sale fixed maturity investments were rated Category 1 and 10.2% were rated Category 2, the two highest ratings assigned by the SVO.

The following table indicates the composition of our fixed income security portfolio (at carrying value) by time to maturity as of December 31, 2015.

(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 Safety Insurance an "A (Excellent)" rating.  Our "A" rating was reaffirmed by A.M. Best on April 13, 2015.  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 (Very Vulnerable)."  Publications of A.M. Best indicate that the "A" rating is assigned to those companies that in A.M. Best's opinion have a strong ability to meet their 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 Safety Insurance'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, where rates, until recently, were historically established by the Commissioner.  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 the Division of Insurance, 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:

In addition, the Commissioner periodically conducts a financial examination of all licensees domiciled in Massachusetts.  We were most recently examined for the five-year period ending December 31, 2013.  The Division had no material findings as a result of this examination.

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 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, 2015, the statutory surplus of Safety Insurance was $571,038 and its net loss for 2015 was $12,209.  A maximum of $57,104 will be available during 2016 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 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.

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 2015, 2014, and 2013 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:

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, 2015, our Insurance Subsidiaries had total adjusted capital in excess of amounts requiring company or regulatory action at any prescribed risk-based capital action level.

Regulation of Private Passenger Automobile Insurance in Massachusetts.  Our principal line of business is Massachusetts private passenger automobile insurance.  Automobile insurance in Massachusetts is regulated under what the Commissioner terms "managed competition", which subjects automobile insurance rates to generally stricter standards that apply in many other states.   Certain of the historically unique factors, also apply in Massachusetts, including compulsory insurance, affinity group marketing, and the prominence of independent agents.

Market Conduct Regulation. Our sales and rating practices are subject to regulation by both the Commissioner and the Massachusetts Attorney General, pursuant to M.G.L. c. 93A. Among other requirements, the premiums we charge must comply with our filed rating plans, which must satisfy Massachusetts law.  The Commissioner has the power to conduct examinations to review our market conduct and the Attorney General can investigate our market conduct through the use of Civil Investigative Demands.

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.

Because we are primarily a private passenger automobile insurance carrier, our business may be adversely affected by conditions in this industry.

Approximately 59.6% of our direct written premiums for the year ended December 31, 2015, 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.

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 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.

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 icestorms, 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 $565,000 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 $565,000.

Climate change 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 which we may not be able to recover, particularly in light of the current competitive environment, and higher reinsurance costs. 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.

There is uncertainty involved in the availability of reinsurance and the collectability of reinsurance recoverable.

 The Company reinsures a portion of its potential losses on the policies it issues to mitigate the volatility of the losses on its financial condition and results of operations. The availability and cost of reinsurance is subject to market conditions, which are outside of the Company’s control. From time to time, market conditions have limited, and in some cases, prevented insurers from obtaining the types and amounts of reinsurance that they consider adequate for their business needs. 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, as is customary, the Company initially pays all claims and seeks to recover the reinsured losses from its reinsurers. Although the Company reports as assets the amount of claims paid which the Company expects to recover from reinsurers, no assurance can be given that the Company will be able to collect from its reinsurers. If the amounts actually recoverable under the Company’s reinsurance treaties are ultimately determined to be less than the amount it has reported as recoverable, the Company may incur a loss during the period in which that determination is made.

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.

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.

We are subject to comprehensive regulation by Massachusetts and our ability to earn profits may be restricted by these regulations.

General Regulation.    We are subject to regulation by government agencies in Massachusetts, and we must obtain prior approval for certain corporate actions. We must comply with regulations involving:

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 requires 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 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. These assessments are made by the Insolvency Fund to cover the cost of paying eligible claims of policyholders of these insolvent insurers, and by CAR, to recover the shares of net CAR 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 obtain insurance from private insurers. The losses of this 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 in Massachusetts 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.

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, we expect beginning in 2016, 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.

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 a strong 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 and financial condition.

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 and 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.

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, 2015, based upon fair value measurement, 89.4% of our investment portfolio was invested in fixed maturity securities, 9.1% in common equity securities and 1.5% in other invested assets. 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.

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 and financial condition.

Developments in the global financial markets may adversely affect our investment portfolio and overall performance.  Global financial markets have recently experienced unprecedented and challenging conditions. If conditions further deteriorate, our business could be affected in different ways. Continued turbulence in the U.S. economy and contraction in the credit markets could adversely affect our profitability, demand for our products or our ability to raise rates, and could also result in declines in market value and future impairments of our investment assets.

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 and to increase our underwriting capacity, 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. 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 and financial condition.

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, prevent shareholders from taking action by written consent, prevent shareholders from calling a special meeting of shareholders, provide for supermajority voting requirements to amend our certificate of incorporation and certain provisions of our bylaws 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.

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 41.6% 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.

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 and 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. 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. 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 exposed to litigation, compliance costs or reputational damage. 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 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.

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 2.    PROPERTIES

We conduct most of our operations in approximately 104 thousand square feet of leased space at 20 Custom House Street in downtown Boston, Massachusetts.  Our lease expires in December 2018.

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 December 15, 2015, the Company filed for arbitration with a reinsurer in regards to the reinsurance recoverable resulting from the 2015 winter storm losses that are admissible under our contract.

ITEM 5.    MARKET FOR THE REGISTRANT'S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

As of February 17, 2016, there were 25 holders of record of the Company's common stock, par value $0.01 per share, and we estimate another 9,400 held in "Street Name."

The closing price of the Company's common stock on February 17, 2016 was $56.80 per share.

During 2015 and 2014, the Company’s Board of Directors declared four quarterly cash dividends to shareholders, which were paid and accrued in the amounts of $41,994 and $39,499, respectively.  On February 16, 2016, the Company's Board of Directors declared a quarterly cash dividend of $.70 per share to shareholders of record on March 1, 2016 payable on March 15, 2016. The Company plans to continue to declare and pay quarterly cash dividends in 2016, 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, to be held on May 18, 2016 in Boston, MA, which the Company intends to file with the U.S. Securities and Exchange Commission within 120 days after December 31, 2015 (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 12, Share Repurchase Program, of this Form 10-K.
