PART I.

ITEM 1. BUSINESS

A.    General

        We are a leading provider of private passenger automobile insurance in Massachusetts. In addition to private passenger automobile insurance (which represented 81.5% of our direct written premiums in 2002), 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 through our insurance subsidiaries, Safety Insurance Company and Safety Indemnity Insurance Company, we have established strong relationships with 524 independent insurance agents in 627 locations throughout Massachusetts. We have used these relationships and our extensive knowledge of the Massachusetts market to become the third largest private passenger automobile carrier, capturing a 10.4% share of the Massachusetts private passenger automobile insurance market, and the fourth largest commercial automobile carrier, with a 7.2% share of the Massachusetts commercial automobile insurance market, in 2002 according to statistics compiled by Commonwealth Automobile Reinsurers ("CAR"). In addition, we were also ranked the 53^rd largest personal automobile writer in the country according to A.M. Best, based on 2001 direct written premiums.

        Our share of the Massachusetts private passenger automobile insurance market has grown from 7.7% in 1998 to 10.4% in 2002. As a result of this increased market share and expanding our product offerings, our direct written premiums have increased by 79.7% between 1998 and 2002, from $287.5 million to $516.6 million. We have also maintained profitability in part by managing our cost structure through, for example, the use of technology.

Our Competitive Strengths

        We Have Strong Relationships with Independent Agents.    In 2001, independent agents accounted for approximately 77% of the Massachusetts private passenger automobile insurance market measured by direct written premiums as compared to only about 34% nationwide, according to A.M. Best. For that reason, our strategy is centered around, and we sell exclusively through, a network of 524 independent agents (of which 110 are Exclusive Representative Producers ("ERPs") in 627 locations throughout Massachusetts. In order to support our independent agents and enhance our relationships with them we:

•

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



•

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



•

Offer our agents competitive commission schedules and profit sharing programs.

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

        We Have an Uninterrupted Record of Profitable Operations.    In every year since our inception in 1979, we have been profitable and increased our direct written premiums from the prior year. We have achieved profitable growth by, among other things:

•

Increasing the number of private passenger automobile exposures we underwrite from 301,000 in 1998 to 436,000 in 2002 and the average premium we receive per automobile exposure from $766 to $967;



•

Maintaining an adjusted statutory combined ratio that is consistently below industry averages;



•

Taking advantage of the institutional knowledge our management has amassed during our long operating history in the unique Massachusetts market;



•

Introducing new lines of insurance products, such as homeowners, which unlike personal auto do not have state-established maximum premium rates;



•

Investing in technology, to simplify internal processes and enhance our relationships with our agents; and



•

Maintaining a high-quality investment portfolio.

        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 Safety. In our largest business line, private passenger auto insurance, our agents now submit approximately 98% of all applications for new policies or endorsements for existing policies to us electronically through our proprietary information portal, the Agents Virtual Community. Second, our investment in technology has allowed us to re-engineer internal back office processes to provide more efficient service at lower cost. Our adjusted statutory expense ratios have been below the average industry statutory expense ratio in each of the past five years. Our systems have also improved our overall productivity, as evidenced by our direct written premiums per employee increasing to $978,400 in 2002.

        We Have an Experienced, Committed and Knowledgeable Management Team.    Our Management Team owns approximately 11% of the common stock of Safety on a fully diluted basis. Our Management Team, led by our Chief Executive Officer and President David F. Brussard, has an average of over 27 years of industry experience per executive, as well as an average of over 21 years of experience with Safety. The team has demonstrated an ability to operate successfully within the regulated Massachusetts private passenger automobile insurance market.

Our Strategy

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

•

Further penetrate the Massachusetts private passenger automobile insurance market;



•

Continue to selectively cross-sell homeowners, dwelling fire, personal umbrella and business owner policies in order to capture a larger share of the total Massachusetts property and casualty insurance business written by each of our independent agents;



•

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

B.    The Massachusetts Property and Casualty Insurance Market

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

        The Massachusetts Market for Private Passenger Automobile Insurance.    Private passenger automobile insurance is heavily regulated in Massachusetts. In many respects, the private passenger automobile insurance market in Massachusetts is unique, in comparison to other states. This is due to a number of factors, including unusual regulatory conditions, the market dominance of domestic companies, the relative absence of large national companies, and the heavy reliance on independent insurance agents as the market's principal distribution channel. For many insurance companies, these factors present substantial challenges, but we believe they provide us a competitive advantage, because, as our financial history shows, we have a thorough understanding of this market.

        The principal factors that generally distinguish the Massachusetts private passenger automobile insurance market from that market in other states are as follows:

•

Compulsory Insurance.  Massachusetts motorists must obtain automobile insurance prior to registering a vehicle with the Registry of Motor Vehicles. Insurers are required to notify the Registry of Motor Vehicles when coverage is cancelled and the Registry of Motor Vehicles is authorized to seize the license plates of uninsured motor vehicles.



•

"Take All Comers."  With very few exceptions, insurers may not refuse to cover an applicant. Insurers may not refuse to issue a policy to an applicant based on the applicant's driving record or other underwriting criteria commonly used by insurers in other states to decide whether to insure a motorist.



•

Standard Policy Form.  The policy form that is used by all auto insurers is developed by the Commissioner and must be used by all companies. The policy consists of several mandatory coverages: no fault coverage (i.e., "personal injury protection"); minimum limits of bodily injury and property damage liability coverage; and coverage for accidents caused by uninsured or hit-and-run motorists. In addition to these standard mandatory coverages, several additional optional coverages (such as higher bodily injury and property damage coverages, and collision and comprehensive coverages) must be offered. No carrier may offer any other type of coverage or deductible or use any form of policy endorsement without the prior approval of the Commissioner, which can be granted only after a formal hearing.



•

Premium Rates are "fixed and established" by the Commissioner.  In Massachusetts, automobile insurance companies are obligated to use premium rates that are determined on an annual basis by the Commissioner. As a matter of law, the Commissioner's rate must be adequate, which the Massachusetts courts have ruled requires that the rate be sufficient to allow insurers the opportunity to earn a reasonable rate of return. The rate setting process involves a lengthy and complex administrative proceeding in which the Commissioner considers historic information related to claim costs as well as outside factors affecting insurance costs. Different data is presented for the Commissioner's consideration by the Automobile Insurers Bureau (on behalf of the insurance industry), the State Rating Bureau, and the Massachusetts Attorney General. At the close of this proceeding, the Commissioner sets a premium rate for each of several classes of drivers, many different types of vehicles, and twenty-seven different geographic territories within Massachusetts. The Commissioner usually sets the rate during the last quarter of the year. The Commissioner mandated no rate change in personal automobile premiums for 2002, an average 8.3% decrease in 2001, and an average rate increase of 0.7% in 2000. The Commissioner announced on December 13, 2002, a 2.7% statewide average rate increase for 2003. In addition, the Commissioner annually establishes the minimum commission rate that insurers must pay their private passenger auto insurance agents. The Commissioner approved a decrease in the

3

commission rate, as a percentage of premiums to 11.7% in 2002 from 12.3% in 2001, and 11.8% in 2000. The Commissioner approved a decrease in the commission rate to 11.0% in 2003.

•

Safe Driver Insurance Plan.  In other states, insurance companies are free to design their own systems for rewarding drivers with superior driving records by providing lower prices to such drivers and charging higher prices for drivers who have caused claims or who have poor driving records. In Massachusetts, all companies must use the system the Commissioner has developed. Known as the Safe Driver Insurance Plan, the system consists of a series of steps, ranging from Step 9 to Step 35, with each step above or below Step 15 granting premium credits to motorists in lower steps (Steps 9 to 14) or imposing surcharges on motorists in higher steps (Steps 16 to 35). Each driver is assigned a step classification by the state. The Safe Driver Insurance Plan system is revenue neutral, which means that the aggregate cost of the discounts must be funded by the aggregate income of the surcharges. The effect of this system is that bad drivers actually pay less than the actuarially appropriate premium and are subsidized by better drivers, who pay more than the actuarially appropriate premium. At Safety, we have a number of strategies that we use to maximize the number of lower step (credit eligible) drivers that we insure.



•

Price competition is limited.  An insurer may charge less than the Commissioner's fixed and established premium rates by offering discounts to all members of a particular class of motorists but only if the discount is approved by the Commissioner after a public hearing. During the years 1996 to 2001, most insurance companies offered rate discounts for drivers with the best driving records. We offered competitively priced discounts during the 1996 to 2001 time period, but like most of our competitors, we have discontinued using these discounts for 2002 and 2003. Only five companies are offering such discounts in 2003.



•

Affinity Group Marketing.  In addition to the use of class discounts, insurers can charge lower rates than the Commissioner's fixed rate by providing discounts to all members of an affinity group. An affinity group consists of all of the employees of a particular employer or the members of a trade union, association or other organization. These discounts must be filed with the Commissioner and are subject to the Commissioner's disapproval. We currently offer discounts to 211 groups representing approximately 13.0% of the private passenger policies we issue, with discounts ranging from 3% to 5%.



•

Exclusive Representative Producers.  As noted above, the Commissioner sets a different rate for each of twenty-seven territories in Massachusetts. The methodology the Commissioner uses to adjust the rates among each territory results in the reduction of rates in high cost urban communities from the actuarially appropriate rate while increasing rates in suburban and rural parts of Massachusetts. As a result, in the aggregate, rates in urban communities are considered inadequate by most insurers. In order to ensure that motorists living in such communities have access to automobile insurance, licensed insurance brokers located in such areas who have not been appointed as a voluntary agent of a company may apply to CAR, to be appointed as an involuntary agent of an insurer selected by CAR. ERPs are randomly assigned to all insurers writing personal auto insurance in Massachusetts. ERP assignments are intended to be based upon an insurer's market share.



•

Commonwealth Automobile Reinsurers.  In order to protect insurers from the potential adverse effect of the Commonwealth's take-all-comers law and the random assignment of ERPs, the Massachusetts Legislature created CAR, which runs a reinsurance pool. CAR is governed by a committee that is appointed by the Commissioner, but its rules and decisions are subject to the review and approval of the Commissioner. Companies may cede to the reinsurance pool policies that they determine are not likely to be profitable. As a result, CAR operates at an underwriting deficit. This deficit is allocated among every automobile insurance company based on a complex formula that takes into consideration a company's voluntary market share, the amount of

4

business it cedes to CAR and credits the company earns under a system CAR has designed to encourage carriers to voluntarily write business in selected under priced classes and territories. We have developed underwriting and actuarial analysis systems to evaluate the profitability of ceding a risk to CAR or writing it voluntarily. Proposals to change certain of CAR's rules are currently under consideration.

•

Dominance of Domestic Companies.  Many large national private passenger automobile insurance writers, such as State Farm, Allstate, Nationwide, and Farmers, write very little or no personal automobile insurance business in Massachusetts. We actively participate in major industry policy-making organizations in Massachusetts, such as the Automobile Insurers Bureau and CAR, where our employees serve on a number of committees.



•

Prominence of Independent Insurance Agents.  Finally, and perhaps most importantly to our Company's success, approximately 77% of the direct written premiums in the Massachusetts private passenger automobile insurance market were placed by independent agents in 2001, according to A.M. Best. Nationally, independent agents wrote only about 34% of the private passenger automobile insurance market in 2001, according to A.M. Best. Accordingly, to be successful, a company must have a strategy designed to encourage the best agents to place their best business with that company. At Safety, we have designed a system of agent commissions, profit sharing, bonuses and other strategies, such as our information technology capabilities, that we believe favorably distinguishes our company among agents. We aggressively market our company among the independent agents in attempting to get the best agents and the best business.

C.    Products

        Historically, we have focused on underwriting private passenger automobile insurance. 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 through selling multiple Safety products. 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 (81.5% of 2002 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 Safe Driver Insurance Plan rate deviations since 1996. In 2002 and 2003, we did not file for any Safe Driver

5

Insurance Plan deviation. We currently offer approximately 211 affinity group discount programs ranging from 3% to 5% discounts.

        Commercial Automobile (9.9% of 2002 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 with qualifying risks eligible for preferred lower rates. We received approval for a rate increase of 7.1% for our commercial automobile line effective December 16, 2002.

        Homeowners (7.4% of 2002 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% for eight years of loss free experience, along with a discount of 10% when a home is written together with an automobile. All forms of homeowner's coverage are written at a standard rate with qualifying risks eligible for preferred lower rates. We received approval for a rate increase of 9.3% effective February 19, 2003.

        Business Owner (Less than 1.0% of 2002 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 (Less than 1.0% of 2002 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 (Less than 1.0% of 2002 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 a discount of 10% when an umbrella policy is written together with an automobile insurance policy. We write policies at standard rates with limits of $1.0 million to $5.0 million.

        Dwelling Fire (Less than 1.0% of 2002 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 a discount of 5% 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.

6

        Commercial Umbrella (Less than 1.0% of 2002 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 $1.0 million to $5.0 million.

        Inland Marine (Less than 1.0% of 2002 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 $5,000 must meet our underwriting guidelines and be appraised.

        Watercraft (Less than 1.0% of 2002 direct written premiums).    We offer watercraft coverage for small and medium sized pleasure craft with maximum lengths of 32 feet, values less than $75,000, and maximum speeds of 39 knots. We write this coverage as an endorsement to our homeowner's policies.

        One of the emerging issues in the insurance industry is mold liability and property coverage under homeowners and similar property-related policies. Property damage as a result of mold is uncommon in Massachusetts, unlike in the southern sections of the United States, most notably Texas. Generally, insurance policies exclude mold coverage unless it is the result of a covered loss. However, as a result of the increased public perception that mold liability is a concern for insurers, we have filed and received approval for a number of mold endorsements from the Division of Insurance which limit our mold property exposure to $10,000 on each of our homeowners and dwelling fire policies and limit our liability exposure to $50,000 on these policies. On business owner and commercial package policies, the property coverage is limited to $15,000 per policy and liability coverage is eliminated. We have eliminated mold coverage on our personal umbrella and commercial umbrella polices. These endorsements cover all new and renewal policies in these lines effective on or after September 1, 2002. In addition, 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 Division of Insurance, which limit our liability and property exposure. See "J. Reinsurance", discussed below.

D.    Distribution

        We distribute our products exclusively through independent agents, unlike some of our competitors, which use multiple distribution channels. We believe this gives us a competitive advantage with the agents. We have two types of independent agents, those with which we have voluntarily entered into an agreement, which we refer to as voluntary agents, and those that CAR has assigned to us as ERPs. Our voluntary agents have authority pursuant to our voluntary agency agreement to bind Safety Insurance 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 have 627 offices (some agencies have more than one office) and approximately 3,000 customer service representatives.

        Voluntary Agents.    In 2002, we obtained approximately 75% 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, 2002, we had agreements with 414 voluntary agents. Our voluntary agents are located in all regions of Massachusetts.

        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 average loss ratio (excluding loss adjustment expenses) of 64.0% or less on the portion of the agent's portfolio that we would underwrite; (iii) currently write policies for a minimum

7

of two automobile carriers; (iv) make a commitment for us to underwrite at least 500 policies from the agency during the first twelve months after entering an agreement with us; and (v) 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 3% of our direct written premiums in 2002.

        Exclusive Representative Producers.    In 2002, our ERPs generated approximately 25% of our direct written premiums for automobile insurance. As of December 31, 2002, we had 80 private passenger automobile ERPs. CAR defines ERPs as licensed dwelling fire or casualty insurance agents or brokers who have a place of business in Massachusetts, but have no existing voluntary independent agency relationship with an automobile insurer conducting business in Massachusetts. An ERP's policy portfolio typically includes a significant percentage of what are considered to be under-priced automobile policies.

        Massachusetts law guarantees the provision of motor vehicle insurance coverage to all qualified applicants. To facilitate this system, any independent agent that is unable to obtain a voluntary automobile relationship with an insurer becomes an ERP and is assigned to an insurer, which is then required to write that agent's policies. The number of mandated ERP policies assigned to a Massachusetts insurance carrier is intended to be proportionate to its voluntary market share. However, because no insurer can control the relative volumes of voluntary and ERP business with certainty, carriers are usually either relatively oversubscribed or undersubscribed with ERP policies. Periodically, CAR assigns or re-assigns an ERP to the most undersubscribed insurer.

        We continuously monitor our ERP subscription level to attempt to reduce our exposure to becoming oversubscribed with ERP business. By properly managing our ERP subscription levels, we reduce the probability that we will be forced to write excessive levels of ERP business, which is usually unprofitable. According to the February 2003 CAR Private Passenger Subscription Report, as of November 30, 2002, our ERP policies totaled 111,929, or approximately 99.51% of our market share percentage of ERP policies, making us the fourth most undersubscribed carrier as of that date.

        From time to time, as our market share grows, we are required to add a new ERP. When we need to add an ERP, we can either negotiate an agreement to obtain one we select from an oversubscribed carrier or have CAR assign one to us.

E.    Marketing

        We view the independent agent as our customer and business partner. As a result, our marketing efforts focus on developing interdependent relationships with leading Massachusetts 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. We do not market ourselves to potential policyholders.

        Our principal marketing strategies are:

•

To offer a range of products, which we believe enables our agents to meet the insurance needs of their clients, and overcomes agents' resistance to placing their clients' auto insurance and other coverages with different insurers;



•

To price our products competitively, including offering discounts when and where appropriate for safer drivers and for affinity groups, and also offering account discounts for policyholders that have both an automobile and homeowners policy with us;

8

•

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



•

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

        Commission Schedule and Profit Sharing Plan.    We have several programs designed to attract profitable new personal auto business from agents by paying them more than the minimum commission the law requires (which is 11.7% of premiums for 2002, and 11.0% in 2003). We recognize our top performing agents by making them members of our President's Club or Executive Club. In 2002 and 2003, President's Club members receive a commission equal to 15.0% of premiums for each new policy with a driver in Safe Driver Insurance Plan step 9 or 10, while Executive Club members receive a commission equal to 13% of premiums for such policies. President's Club members can earn an additional bonus of 5% of premiums, and Executive Club members can earn an additional bonus of up to 3% of premiums, on all new step 9 and 10 business, in each case if the average of the Safe Driver Insurance Plan steps of all new business based on automobile exposures they submit during the year is 11.5 or less. In part as a result of these programs, in 2001, 69.9% of our drivers were in Safe Driver Insurance Plan steps 9 or 10, as compared to 68.9% for the Massachusetts personal auto industry as a whole, based on the number of drivers per month in each step according to the Automobile Insurers Bureau.

        Further, we have a competitive profit sharing program under which we pay agents up to 50% of the underwriting profits 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. This investment includes providing each of our agents with high-speed access to the Internet through a network, which we own. In addition, our Agents Virtual Community website helps agents manage their work efficiently. We provide a substantial amount of information online that agents need to serve their customers, such as information about the status of new policies, bill payments and claims. Providing this type of content reduces the number of customer calls we receive and empowers the agency'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 enhance the quality of support we provide.

F.    Underwriting

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

•

Pricing of discounts offered on our policies;



•

Determining which policies to cede to CAR's reinsurance pool and which to retain; and



•

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

        In addition to our private passenger auto underwriting unit, our underwriting department includes a separate unit of underwriters for homeowners, dwelling fire, personal umbrella and inland marine coverages, as well as a separate unit for commercial coverages, including commercial auto, business owner, commercial umbrella and commercial package policies.

        Pricing.    Our pricing strategy for personal auto insurance primarily depends on the maximum permitted premium rates and minimum permitted commission levels mandated by the Division of Insurance. For several years prior to 2002, we offered discounts off the state-mandated rates to drivers

9

in the lower Safe Driver Insurance Plan steps, as did a number of other insurers. However, starting in 1998, we began to reduce the discounts we offered, in light of the reductions or minimal increases in average rates the Commissioner has mandated in each year since 1998. We currently do not offer any Safe Driver Insurance Plan step-based discounts. As a result primarily of reducing discounts and of our insureds purchasing new cars (for which we are permitted to charge higher premiums), our average premium received per policy increased 7.4% in 2000, did not change in 2001, and increased 5.2% in 2002.

        In addition to Safe Driver Insurance Plan discounts, we also offer group discounts to members of 211 affinity groups, including the Boston College Alumni Association, the Massachusetts Bar Association and the Massachusetts Medical Society. In general, we target affinity groups with a mature and stable membership base along with favorable driving records, offering between a 3% and 5% discount (with 4% being the average discount offered). Approximately 13.0% of the private passenger policies we issue receive an affinity group discount.

        CAR and the Division of Insurance set the premium rates for commercial automobile policies reinsured through CAR. Subject to Division of Insurance review, we set rates for 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. We base our rates on industry loss cost data, our own loss experience, catastrophe modeling and prices charged by our competitors in the Massachusetts market. We received approval for a rate increase of 7.1% for our commercial automobile line effective December 16, 2002, and also received approval for a rate increase of 9.3% for our homeowners line effective February 19, 2003.

        Cede/Retain Decisions.    Under CAR's rules, we must decide, within 23 days after the effective date of a new policy or before renewing an existing policy, whether to cede it to CAR's reinsurance pool. Each Massachusetts auto insurer must bear a portion of the losses of the reinsurance pool. Under CAR's rules, we are able to reduce our total allocated share of the losses of the reinsurance pool by ceding less business to the pool than our proportionate share. As a result, in determining whether to cede an underpriced policy to CAR's personal auto reinsurance pool, we attempt to evaluate whether we are likely to incur greater total losses by ceding it to the pool or by retaining it. In 2001, we ceded approximately 5% of our personal auto business, based on automobile exposures, to the pool, compared to an average of 7.7% for the rest of the industry. According to the February 28, 2003 CAR Cession Volume Analysis—Private Passenger Report, as of December 31, 2002, we have ceded 7.2% of our personal auto business to the pool in 2002, compared to an average of 7.5% for the industry. Our goal is still to cede less than the industry average to the pool.

        CAR also runs a reinsurance pool for commercial auto policies. We analyze whether to cede or retain our business in that line in a similar fashion.

        Bulk Policy Transfers and New Voluntary Agents.    From time to time, we receive proposals from existing voluntary agents 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 portfolio have a pure loss ratio (which refers to the ratio of losses, excluding loss adjustment expenses, to net earned premiums) of not more than approximately 64%. In addition, we require any new voluntary agent to commit to transfer a portfolio to us consisting of at least 500 policies.

        Policy Processing and Rate Pursuit.    Our underwriting department assists in processing policy applications, endorsements, renewals and cancellations. In the past three years, we have introduced new proprietary software that enables agents to connect to our network and enter policy and endorsement applications for personal auto insurance from their office computers. In our personal automobile

10

insurance line, our agents now submit approximately 98% of all applications for new policies or endorsements for existing policies through our proprietary information portal, the Agents Virtual Community.

        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 Massachusetts 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 preinspection requirements and in some cases the validity of discounts. In our homeowners and dwelling fire lines, our team is currently completing a project to update the replacement costs for each dwelling. We are using newly acquired third-party software to assist in this appraisal effort.

G.    Technology

        The focus of our information technology effort is:

•

constant reengineering of internal processes to allow more efficient operations, resulting in lower operating costs;



•

making it easier for independent agents to transact business with us; and



•

enabling agents to efficiently provide their clients with a high level of service.

        We believe that our technology initiatives have increased revenue and decreased cost. 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 our overall increases in productivity. In 1990, we had 399 employees and $155.0 million in direct written premiums. As of December 31, 2002, we had 528 employees and $516.6 million in direct written premiums, which represents an increase from $388,500 direct written premiums per employee in 1990 to $978,400 direct written premiums per employee in 2002.

        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.

        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. In 2002, our bad debt expense as a percentage of direct written premiums was 0.2%.

        External Applications.    Agency employees can securely access business critical applications through our corporate extranet, which we call Agents Virtual Community. Agents Virtual Community includes

11

Web-enabled applications, advanced security and an Internet-enabled communications network, which we believe constitutes many of our agents' only high-speed Internet connection. We believe that Agents Virtual Community is unique to the Massachusetts private passenger automobile insurance industry because using Agents Virtual Community allows an agent to access a variety of vendors and other carriers over the Internet through a single portal. We currently have a patent application pending on Agents Virtual Community. The patent application pertains to the method and system by which Agents Virtual Community delivers customer services to independent insurance agents. The capability for agency personnel to schedule online appointments with third-party vendors (such as glass repair retailers and rental car agencies) for their clients is also available. We designed Agents Virtual Community to be scalable so that these types of vendors and potentially, other insurers, can link to the network and create a "once and done" environment for the independent agent.

        Listed below are examples of the business critical applications agents may access through Agents Virtual Community.

        New Business and Endorsement Processing.    Agents can perform new business and endorsement processing with our point of sale application. Agents can upload policy data to our system directly from their agency system or rate quote software in Agents Virtual Community's secure Web environment without having to re-enter policy information.

        Inquiry Access.    Inquiry Access is a customer service application designed to provide agency customer service representatives with real-time access to our database of insured information. This application allows agents to view the status of claims, billing and policy detail.

        Policyholder Inquiry.    Policyholder Inquiry provides 24 hours a day, 7 days a week self-service account information to our policyholders through our website or through their independent agent's website. This application provides policyholders with round-the-clock access to billing and claims information.

        Other Tools and Services.    Agents Virtual Community gives agents access to electronic versions of underwriting manuals, which include updated guidelines for acceptable risks, commission levels and product pricing. Further, we have recently launched a new initiative to have our agents use third-party software (the XNET Cost Estimator from Marshall Swift/Boeck) that we make available through Agents Virtual Community to help assess home replacement costs. This initiative helps ensure that we receive the correct premium with respect to homeowners policies and provide the correct level of coverage against home loss. Finally, we provide agents a daily report of all their insurance transactions processed through Agents Virtual Community. This report allows our agents to monitor their performance and review profitability goals.

H.    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 a proven record of settling casualty claims below the industry average in Massachusetts. According to the Automobile Insurers Bureau, our average casualty claim settlement during the period from January 1994 through December 31, 2001 was $5,200, approximately 8% lower than the Massachusetts industry average of $5,660.

        We have adopted stringent claims settlement procedures, which include guidelines that establish maximum settlement offers for soft tissue injuries, which constituted approximately 75% of our bodily injury claims. If we are unable to settle these claims within our guidelines, we generally take the claim to litigation. We believe that these procedures result in providing our adjusters with a uniform approach to negotiation.

12

        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 Bodily Injury Hotline is a telephone and fax system 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. After business hours and on Saturdays, we outsource claims adjustment support to an independent firm whose employees contact third-party claimants and other witnesses. 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 the Commonwealth. Comprising 115 people, the department is organized geographically by territories, each with a territorial claims unit located at our headquarters in Boston and a claims adjuster in the field. Our casualty claims unit makes limited use of independent adjusters.

        Additionally, we utilize a special unit to investigate fraud in connection with casualty claims. This special unit has one manager and seven employees. 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 personal and commercial auto, homeowners and other insurance lines. Process automation has streamlined our property claims function. Many of our property claims are now handled by the agents through Agents Virtual Community 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. Our agents also have the authority to order auto glass or body repair or reserve a rental car for our insureds without getting pre-approval from us. 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 the 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. 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. 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.

I.    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 our reserves internally. Regulations of the Division of Insurance require us to annually obtain a certification from either a qualified actuary or an approved loss reserve specialist that our loss and loss adjustment expenses reserves are reasonable.

13

        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, 2002 is adequate to cover the ultimate net cost of losses and claims incurred as of that date. The ultimate liability may be greater or less than reserves. 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.

        Under purchase accounting in connection with the Company's acquisition of all of the issued and outstanding stock of Thomas Black Corporation ("TBC") on October 16, 2001 ("the Acquisition"), the fair value of our reserves for losses and loss adjustment expenses and related reinsurance recoverables was estimated as of the date of the Acquisition based on the present value of the expected underlying cash flows of the loss reserves and reinsurance recoverables, and included a profit and risk margin. In determining the fair value estimate, management adjusted our historical GAAP undiscounted net loss reserves to present value assuming a 4.0% discount rate, which approximated the U.S. Treasury rate on the date of the Acquisition. The discounting pattern was actuarially developed from our historical loss data. A profit and risk margin of 6.0% was applied to the discounted loss reserves, to reflect management's estimate of the cost we would incur to reinsure the full amount of our net loss and loss adjustment expense reserves with a third party reinsurer. This margin was based upon management's assessment of the uncertainty inherent in the net loss reserves and their knowledge of the reinsurance marketplace. Management determined that there was no material difference between the historical carrying basis of the reserves for losses and loss adjustment expenses and related reinsurance recoverables at the date of Acquisition and their fair value. Accordingly, loss and loss adjustment expense reserves and related reinsurance recoverables on unpaid losses as of October 16, 2001 are recorded at estimated fair value as at October 16, 2001, which approximated carrying value at that date.

14

        The following table presents development information on changes in the reserve for losses and loss adjustment expenses ("LAE") of our insurance subsidiaries for the three years ended December 31, 2002.

        The following table represents the development of reserves, net of reinsurance, for calendar years 1992 through 2002. 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, 2002.

        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 1998 estimate for a previously incurred loss was $150,000 and the loss was reserved at $100,000 in 1994, the $50,000 deficiency (later estimate minus original estimate) would be included in the cumulative redundancy (deficiency) in each of the years 1995-1998 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

15

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.

16

        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, we used to conduct substantial business as a servicing carrier for other insurers, in which we would service the residual market personal 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 prior years from releasing redundant reserves. Massachusetts private passenger automobile insurance pricing was very favorable in the early to mid-1990s and the reserves we established for business written during that period developed favorably, allowing us to release substantial reserves in following years. As maximum permitted rates declined in the latter part of the 1990s through 2002, and the redundancies resulting from favorable development of earlier years were released, our redundancies in subsequent years began to diminish. In the year ended December 31, 2000 we released $27.0 million in reserves relating to prior years, compared to $7.3 million in 2001. For the year ended December 31, 2002, we released loss reserves related to prior years of $2.3 million.

        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.

J.    Reinsurance

        We reinsure with other insurance companies a portion of our potential liability under the policies we have underwritten, thereby protecting us against an unexpectedly large loss or a catastrophic occurrence that could produce large losses. 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 are very 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 continuously evaluate and review the financial condition of our reinsurers. All of our reinsurers have an A.M. Best rating of "A" or better, except for Lloyd's of London, Folksamerica Reinsurance Company, and Montpelier Reinsurance Limited that are all rated "A-." Swiss Re, our primary reinsurer, maintains an A.M. Best rating of "A++" (Superior).

        We maintain reinsurance coverage to help lessen the effect of losses from catastrophic events, maintaining coverage that protects us in the event of a "100-year storm" (that is, a storm of a severity

17

expected to occur once in a 100 year period). We use Catalyst software provided under license by our reinsurance broker, Benfield Blanch, to model the probable maximum loss to us for catastrophe losses such as hurricanes. At present, we have excess catastrophe reinsurance contracts for 95.0% of catastrophic property losses in excess of $5.0 million up to a maximum of $100.0 million.

        We also have a casualty excess of loss reinsurance contract for large casualty losses occurring in our automobile, homeowners, dwelling fire, business owners policies, commercial package policies, personal umbrella and commercial umbrella lines of business in excess of $1.0 million up to a maximum of $5.0 million, with an annual aggregate deductible of $0.5 million. In addition, we have a quota share reinsurance agreement under which we cede 90.0% of the premiums and losses under our personal and commercial umbrella policies. We also have a reinsurance agreement with Hartford Steam Boiler Inspection and Insurance Company, which 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. We have property excess of loss reinsurance coverage for large property losses, with coverage in excess of $1.0 million up to a maximum of $10.0 million, for our homeowners, business owner, and commercial package policies.

        In the wake of the September 11, 2001 tragedies, reinsurers have begun to exclude coverage for claims in connection with any act of terrorism. Our reinsurance program for 2002 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. For business owner policies and commercial package policies, terrorism is excluded if the total insured value is greater than $20.0 million. We received approval from the Division of Insurance effective January 1, 2002 to exclude terrorism coverage for our business owner, commercial umbrella and commercial package policies.

        The Terrorism Risk Insurance Act of 2002 (TRIA) was signed into law on November 26, 2002. 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 TRIA provides reinsurance for certified acts of terrorism. We have filed and been approved by the Division of Insurance to issue policy endorsements for all commercial policyholders to comply with TRIA effective February 24, 2003.

        As of December 31, 2002, we had no material amounts recoverable from any reinsurer, excluding the residual markets described below.

        In addition to the above mentioned reinsurance programs, we are a participant in CAR, the Massachusetts mandated residual market 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 Massachusetts Property Insurance Underwriting Association in which premiums, expenses, losses and loss adjustment expenses on homeowners business that cannot be placed in the voluntary market are shared by insurers writing homeowners insurance in Massachusetts.

K.    Competition

        The property and casualty insurance business is highly competitive and many of our competitors have substantially greater financial and other resources than us. We compete with both large national writers and smaller regional companies. In Massachusetts in 2001, we competed across all our lines of business as the fifth largest property and casualty insurer, according to A.M. Best, with 270 other property and casualty insurers. According to A.M. Best, of the 271 insurers, 20 are national companies which use independent agents to sell their products, 163 are regional or Massachusetts-only companies which use independent agents to sell their products (including us), and 88 are national and Massachusetts-only companies which sell their products directly to policyholders. 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

18

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. In the past, competition in the Massachusetts personal auto market has included offering significant discounts from the maximum permitted rates, and there can be no assurance that these conditions will not recur. Further, we 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 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. There can be no assurance that we will be able to compete effectively against these companies in the future.

        In Massachusetts as of November 30, 2002, 20 insurers actively wrote private passenger auto insurance, according to CAR. Of these 20 insurers, 4 are national companies which use independent agents to sell their products, 8 are regional or Massachusetts-only companies which use independent agents to sell their products (including us) and 8 are national, regional or Massachusetts-only companies which sell their products directly to policyholders. Our principal competitors within the Massachusetts private passenger automobile insurance industry are Commerce Group, Inc. and Arbella Mutual Insurance Company which held 25.9% and 10.4% market shares based on automobile exposures, respectively, in 2002 according to CAR.

L.    Employees

        At March 26, 2003, we employed 513 employees. Our employees are not covered by any collective bargaining agreement. Management considers our relationship with our employees to be good.

M.  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, 2002, there were no securities below investment grade (i.e., rated Category 3 or lower by the Securities Valuation Office of the National Association of Insurance Commissioners) in our fixed income securities portfolio. According to our investment guidelines, no more than 1% of our portfolio may be invested in the securities of any one issuer (excluding U.S. government-backed securities), and no more than 0.5% of our portfolio may be invested in securities rated "BBB," or the lowest investment grade assigned 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, our investment manager has been Deutsche Asset Management, formerly known as Scudder Investments.

19

        The following table reflects the composition of our investment portfolio at December 31, 2002, 2001 and 2000:

(1)

Obligations of U.S. Government agencies include collateralized mortgage obligations issued, guaranteed and/or insured by the following issuers: Government National Mortgage Association (GNMA), Federal Home Loan Mortgage Corporation (FHLMC), and Federal National Mortgage Association (FNMA). As such, the asset-backed securities presented exclude such issuers already presented under U.S. Treasury securities and obligations of U.S. Government Agencies.

        While we have held common equity securities in our investment portfolio in the past, as of December 31, 2002 we held no such securities in our investment portfolio. We made the decision to divest common equity securities in order to maximize the current investment income earned by our portfolio and to reduce our overall investment risk. We continuously evaluate market conditions and we expect in the future to purchase common equity securities.

        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.

20

        The following table reflects our investment results for each year in the three-year period ended December 31, 2002:

Investment Results

(1)

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

(2)

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

(3)

Net investment income plus realized capital gains (losses) for the period divided by average invested securities and cash for the same period.

        Net effective yield declined as a result of a change in management's investment strategy to shorten the duration of our portfolio, shift to higher rated securities, and increase our tax-exempt holdings.

        The following table indicates the composition of our fixed income security portfolio (at carrying value) by rating, as of December 31, 2002:

Composition of Fixed Income Security Portfolio by Rating⁽¹⁾

(1)

Rating as assigned by Moody's Investors Services, Inc., or Moody's. Such 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, Ca and C) are considered to be too speculative to be of investment quality.

21

        The Securities Valuation Office of the National Association of Insurance Commissioners evaluates all public and private bonds purchased as investments by insurance companies. The Securities Valuation Office 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. Securities Valuation Office ratings are reviewed at least annually. At December 31, 2002, approximately 93.4% of our fixed maturity investments were rated Category 1, and 6.6% of our fixed maturity investments were rated Category 2, the two highest ratings assigned by the Securities Valuation Office. At December 31, 2002, we had no fixed maturity investments rated Category 3 or lower by the Securities Valuation Office.

        The following table indicates the composition of our fixed income security portfolio (at carrying value) by time to maturity as of December 31, 2002:

Composition of Fixed Income Security Portfolio by Maturity

(1)

Actual maturities of asset-backed securities 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.

N.    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 November 19, 2002. 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 market 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 reaffirming Safety Insurance's rating, A.M. Best recognized the occurrence of the Acquisition and IPO and noted certain of our positive attributes, including our conservative reserving philosophy,

22

our strict underwriting discipline, our favorable market position as the third largest automobile writer in Massachusetts, our efforts at product diversification, our long-term commitment to the independent agency force, our proven track record of dealing successfully with the changes in the Massachusetts automobile insurance market and our substantial reinsurance protection. A.M. Best cited certain factors that partially offset these attributes, including our geographic concentration in Massachusetts and our focus in the private passenger automobile market. We are subject to the competitive and highly regulated Massachusetts personal automobile market, which has been characterized by aggressive discount programs and mandated rate reductions by the Division of Insurance.

O.    Supervision and Regulation

        Introduction.    Our principal operating subsidiaries, Safety Insurance and Safety Indemnity, are subject to comprehensive regulation by the Division of Insurance ("the Division"), of which the Commissioner is the senior official. The Commissioner is appointed by the Governor and serves at the pleasure of the Governor. We are subject to the authority of the Commissioner in many areas of our business under Massachusetts law, including:

•

our licenses to transact insurance;



•

the premium rates and policy forms we may use;



•

our financial condition including the adequacy of our reserves and provisions for unearned premium;



•

the solvency standards that we must maintain;



•

the type and size of investments we may make;



•

the prescribed or permitted statutory accounting practices we must use; and



•

the nature of the transactions we may engage in with our affiliates.

        In addition, the Division periodically conducts a financial examination of all licensees domiciled in Massachusetts. We were most recently examined for the five-year period ending December 31, 1998. 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 obtain the prior approval of 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.

        Insurance Regulation Concerning Dividends.    We rely on dividends from our insurance company subsidiaries for our cash requirements. The insurance holding company law of Massachusetts requires notice to the Commissioner of any dividend to the stockholders of an insurance company. Our insurance company 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% 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

23

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 year-end 2002, the statutory surplus of the Company was $234.2 million and its net income for 2002 was $20.4 million. A maximum of $23.4 million will be available by the end of 2003 for such dividends without prior approval of the Division.

        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% or more of our outstanding voting stock. Even persons who do not acquire beneficial ownership of more than 10% 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% or more of the voting power of our capital stock will be presumed to have acquired control of our Massachusetts 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. The Massachusetts Insurers Insolvency Fund must pay any claim up to $0.3 million 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 Massachusetts Insurers Insolvency Fund are assessed the amount the Massachusetts Insurers Insolvency Fund deems necessary to pay its obligations and its 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 Massachusetts Insurers 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 Massachusetts Insurers Insolvency Fund. With respect to private passenger auto insurance rates and premiums, the Commissioner has historically made an adjustment in his or her annual rate decision reflecting any Massachusetts Insurers Insolvency Fund-related costs reported by the industry in its rate filing. 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. In 2001, we were assessed $1.4 million, primarily as the result of the insolvencies of The Trust Insurance Company and Reliance Insurance Company. In 2002, we were assessed $2.1 million for these insolvencies, as well as the insolvencies of other insurers. We account for allocations from the Massachusetts Insurers Insolvency Fund as underwriting expenses. Underwriting expenses in 2002 and 2001 included $2.1 million and $1.4 million of charges representing our allocation from the Massachusetts Insurers Insolvency Fund for the insolvencies of The Trust Insurance Company and Reliance Insurance Company. 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 Massachusetts Insurers Insolvency Fund, CAR must increase each of its member's share 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 additional assessments from time to time relating to various insolvencies.

        The Insurance Regulatory Information System.    The Insurance Regulatory Information System was developed to help state regulators identify companies that may require special financial attention. The Insurance Regulatory Information System consists of a statistical phase and an analytical phase whereby

24

financial examiners review annual statements and financial ratios. The statistical phase consists of 12 key financial ratios based on year-end data that are generated from the National Association of Insurance Commissioners' database annually; 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 Insurance Regulatory Information System 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. For 2002, all our ratios for both our insurance companies were within the normal range. However, for 2001, our subsidiaries had one ratio falling outside the normal range. The test that measures estimated current reserve deficiency to surplus generated a value for 2001 of 30.3% for Safety Insurance and 27.6% for Safety Indemnity Insurance Company, each exceeding the normal value of 25%. The value is partially a result of our adoption of statutory accounting principles promulgated by the National Association of Insurance Commissioners in 2001. In particular, our treatment for assumed obligations for underwriting pool business from CAR and the Massachusetts Property Insurance Underwriting Association plan changed from "netting" (recording the combined obligation from premiums, expenses and losses) to "gross" (recording separate amounts for premiums, expenses and losses, which resulted in reporting a net loss). The level of premiums earned for 2001 is thereby increased relative to the levels reported during 1999 and 2000, influencing the results of this ratio. This same test resulted in a ratio of 5.0% for both our insurance companies for 2002, within the normal range.

        Risk Based Capital Requirements.    The National Association of Insurance Commissioners has adopted a formula and model law to implement risk based capital requirements for most property and casualty insurance companies, which are designed to determine minimum capital requirements and to raise the level of protection that statutory surplus provides for policyholder obligations. The risk based capital formula for property and casualty insurance companies measures three major areas of risk facing property and casualty insurers:

•

underwriting, which encompasses the risk of adverse loss developments and inadequate pricing;



•

declines in asset values arising from market and/or credit risk; and



•

off-balance sheet risk arising from adverse experience from non-controlled assets, guarantees for affiliates or other contingent liabilities and reserve and premium growth.

        Under Massachusetts law, insurers having less total adjusted capital than that required by the risk based capital calculation will be subject to varying degrees of regulatory action, depending on the level of capital inadequacy.

        The risk based capital law provides for four levels of regulatory action. The extent of regulatory intervention and action increases as the level of total adjusted capital to risk based capital falls. The first level, the company action level as defined by the National Association of Insurance Commissioners, 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 National Association of Insurance Commissioners 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% of the risk based capital amount. The authorized control level, as defined by the National Association of Insurance Commissioners, 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.,

25

rehabilitation or liquidation, if total adjusted capital falls below 100% of the risk based capital amount. The fourth action level is the mandatory control level as defined by the National Association of Insurance Commissioners, which requires the Commissioner to place the insurer under regulatory control if total adjusted capital falls below 70% 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, 2002, 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. As described in more detail above under "B. The Massachusetts Property and Casualty Insurance Market", regulation of private passenger automobile insurance in Massachusetts differs significantly from how this line of insurance is regulated in other states. These differences include the requirements that we not deny coverage to any applicant; that the premium rate we and all insurers must charge is fixed and established by the Commissioner; that our ability and that of our competitors to deviate from the rate set by the Commissioner is restricted, and that some of our insurance producers are assigned to us as a matter of law. See "B. The Massachusetts Property and Casualty Insurance Market", discussed above.

ITEM 2. PROPERTIES

        We conduct our operations in approximately 86,930 square feet of leased space at 20 Custom House Street in downtown Boston, Massachusetts. Our lease expires in December 2008.

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. Other than these lawsuits, we are not involved in any legal proceedings.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

        There were no matters submitted to a vote of the Company's shareholders during the fourth quarter of 2002.

PART II.

ITEM 5. MARKET FOR THE REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS

        As of March 28, 2003, there were 39 holders of record of the Company's common stock, par value $0.01 per share, not including stock held in "Street Name".

        The Company's common stock (symbol: SAFT) is listed on the NASDAQ National Market. The quarterly range of the daily high and low sales price for Common Shares during 2002 is presented below:

        The closing price of the Company's common stock on March 28, 2003 was $13.00 per share.

        During 2002 the Company did not declare or pay any cash dividends to stockholders. The Company's Board of Directors declared a quarterly cash dividend on February 20, 2003 of $0.07 per share to stockholders of record on March 3, 2003, payable on March 17, 2003. The Company plans to continue to declare and pay quarterly cash dividends in 2003, depending on the Company's financial position and the regularity of its cash flows.

        The Company relies on dividends from its insurance company subsidiaries, Safety Insurance Company and Safety Indemnity Insurance Company (the "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 subsidiaries. The payment of dividends by the subsidiaries is subject to limitations imposed by Massachusetts law, as discussed in Item 1.O., Business, Supervision and Regulation, "Insurance Regulation Concerning Dividends", and also in Item 7.D., Management's Discussion and Analysis of Financial Condition and Results of Operations, Liquidity and Capital Resources.
