PART I
Item 1. Business
General
      ProCentury Corporation (“ProCentury,”) is a specialty property and casualty insurance holding company. We market and underwrite general liability, commercial property, multi-peril insurance and garage liability for small and mid-sized businesses primarily through Century Surety Company (“Century”), our operating insurance subsidiary. References to “Company”, “we”, “us”, and “our” refer to ProCentury and its subsidiaries, unless the context requires otherwise. We are either authorized as an admitted insurer or approved as an excess and surplus lines insurer by the state insurance regulators in 48 states plus the District of Columbia. We primarily write specialty excess and surplus lines insurance through a select group of general agents. The excess and surplus lines market provides an alternative market for customers with hard-to-place risks that insurance companies licensed by the state in which the insurance policy is sold, which are also referred to as “admitted insurers,” typically do not cover. Our goal is to be selective in the classes of business and the coverages we write within the excess and surplus lines market. The insurance needs of this market are serviced by retail insurance brokers who maintain relationships with the general agents with whom we do business.
      As a “niche” company, we offer specialty insurance products designed to meet specific insurance needs of targeted insured groups. These targeted insured markets are often not served or are underserved by standard companies. We focus on serving the insurance needs of small and mid-sized businesses, including habitational risks, hospitality businesses, artisan contractors, daycare facilities, retail and wholesale stores, fitness centers and special event providers. Typically, the development of these specialty insurance products is generated through proposals brought to us by an agent or broker seeking coverage for a specific group of clients. We have disciplined underwriting that considers all of our applicants for insurance coverages on an individual basis. For each class we insure, we employ a number of customized limiting endorsements, rating surcharges and decreased limits to align our product offerings to the risk profile of the class and the specific insured being underwritten.
      We seek to achieve a balance between our property and casualty premiums. Property business has an inherently shorter tail than casualty business, and we emphasize short tail classes of casualty business in order to reduce pricing and reserving risk. For example, our primary casualty business is dominated by premises liability risks known in the industry as Owners, Landlords & Tenants (“OL&T”) risks, which presents a much shorter tail than a traditional excess and surplus lines book of business, which is predominated by Manufacturers & Contractors (“M&C”) risks. Short tail risks are generally known to occur at a definite point in time, and while the extent of the injury and associated costs may be unknown for some period of time, the actual occurrence is usually reported fairly quickly. In contrast, with longer tail risk the injury occurs away from the premises owned by the insured, may not be known for some period of time and may result in cumulative or progressive damage.
      We avoid high-hazard, long tail lines of business such as product liability, occurrence coverage for general contractor liability and construction contractor liability business and medical malpractice. We believe that construction trades may no longer be profitably underwritten on an occurrence general liability form in any state.
      As of December 31, 2004, we had consolidated assets of $394.9 million and consolidated shareholders’ equity of $115.2 million. For the year ended December 31, 2004, we produced gross written premiums of $191.4 million, and we had net income of $15.0 million
      Our principal executive offices are located at 465 Cleveland Ave., Westerville, Ohio 43082, and the telephone number at that address is (614) 895-2000. The Company files annual, quarterly, special reports and proxy statements with the SEC. These filings are available to the public over the Internet on the SEC’s Web site at http://www.sec.gov and at our Web site at http://www.procentury.com.

      Pursuant to Rule 12b-23 under the Securities and Exchange Act of 1934, as amended, the industry segment information included in Item 8, note 14 of Notes to Consolidated Financial Statements, is incorporated by reference in partial response to this Item 1.
Company History
      Century was formed in 1978 as a specialty insurance carrier for inland marine, surety and fidelity coverages for the surface mining industry. In 1984, Century expanded its original focus and initiated a business strategy centered on hard to place property/casualty risks. In 1992, Century acquired Continental Heritage Insurance Company (“Continental”), which wrote specialty surety and bail bond business. In 1993, Century acquired Evergreen National Indemnity Company (“Evergreen”), which wrote landfill and specialty surety business. These combined entities constituted the Century Insurance Group®.
      In 1996, Century was acquired by Century Business Services, Inc. (Nasdaq: CBIZ). In 1997, as part of a growth initiative by its former parent, Century Insurance Group® acquired the assets of the managed care workers’ compensation business of the Anthem Casualty Insurance Group.
      ProCentury was formed as an Ohio corporation in July 2000 by certain of our current shareholders and members of management. Pursuant to our management-led buyout in October 2000, ProCentury acquired Century and its subsidiaries, including Evergreen and Continental, from Century Business Services, Inc. The financing of this transaction included equity investments by five community bank holding companies, a private equity firm and other private investors, including members of current management.
      Following this transaction, the strategic direction of ProCentury focused primarily on the excess and surplus lines and involved exiting certain unprofitable businesses such as commercial automobile beginning in May 2000 and workers’ compensation in January 2002. As a result of this change in strategy, we sought to take advantage of the increase in volume and rates in the excess and surplus lines market, which began in 2001.
      On April 26, 2004, we issued 8,000,000 common shares at $10.50 per share in an initial public offering (“IPO”) and received net proceeds (before expenses) of $77.9 million. Immediately prior to the IPO, Evergreen and Continental, were spun-off to ProCentury’s existing Class A shareholders. The operations of Evergreen and Continental consisted of ProCentury’s historical surety and assumed workers’ compensation lines of insurance, which were re-classified (net of minority interest and income taxes) as discontinued operations in the accompanying financial information for all periods presented. As a result of these transactions, Century is the remaining operating subsidiary of ProCentury.
Industry Overview
      The excess and surplus lines insurance market differs significantly from the standard market. In the standard market, insurance products and coverages are largely uniform with broad coverage grants due to highly regulated rates and forms. Standard market companies tend to compete for customers primarily on the basis of rate, retain close relationships with retail insurance agents and make accommodations to the insureds to maintain the marketability of their product for their contracted direct agent.
      In contrast, the excess and surplus lines market provides coverage for risks that either do not fit the underwriting criteria of standard carriers with which the retail agent has a direct relationship, or they are of a class or risk that the standard market generally avoids since the regulated nature of that market does not allow for customized terms or rates. Non-standard risks can be underwritten profitably, however, by the excess and surplus market, by using highly specific coverage forms with terms based on individual risk assessment, rather than the risk profile of the most desirable members of the class. When a certain risk has been excluded from the standard market, the retail agents needs quick placement with the excess and surplus lines market in order to maintain coverage for the insured. As a result, the primary basis for competition within the excess and surplus lines industry can be focused more on service and availability than rate.
      The insurance industry has historically been cyclical. From 1987 to 2001, the industry generally experienced intensified competition for standard and excess and surplus lines insurers, resulting in rate decreases in many lines. In early 2001, a return to risk-based underwriting disciplines in the standard market

Table of Contents

caused a noticeable increase in submissions to the excess and surplus lines market of risks that no longer qualified for coverage from the standard carriers and higher premium rates. Since 2001, we have benefited from this increase in rates and volume, as well as reduced capacity in the excess and surplus lines market, insurance industry consolidation, corporate downsizing and the increased use of communications technology and personal computers, which, among other factors, have contributed to the high growth in the number of small businesses. In addition, low interest rates have resulted in increased rates and more conservative coverage terms because, as investment returns have moderated over the past few years, property and casualty carriers have been forced to adopt more profitable underwriting practices. For property business, this pattern continued until the second half of 2003, when rates first plateaued, and then slowly began to decline. This moderate decline continued throughout much of 2004, with some stabilization seen after the October hurricanes in Florida. For casualty business, rates remained firm throughout 2003 and stabilized in 2004 with only slight declines.
      We expect that rate adequacy for our specialty and excess and surplus lines products will continue, as a result of the following factors:
  •  our commitment to underwriting profitability;
 
  •  our re-underwriting of our binding policies;
 
  •  continued low interest rates;
 
  •  close monitoring or downgrading of many insurers and reinsurers by rating agencies;
 
  •  new corporate governance requirements; and
 
  •  industry focus on rate adequacy and the negative effects of under-priced business on the industry as a whole.

Property/ Casualty
      Casualty Business. We target shorter tail classes of casualty business focusing on what are commonly referred to as “OL&T” (owners, landlords and tenants) classes of business and have de-emphasized what are commonly referred to as “M&C” (manufacturers and contractors) classes of business. We believe these shorter tail OL&T classes of business present less rating and reserving risk to us compared to longer tail casualty lines. At the time of our management-led buyout in October 2000, 46.5% of our property/casualty gross written premiums comprised OL&T or shorter tail classes. For the year ended December 31, 2004, 71.8% of our property/casualty gross written premiums comprised OL&T or shorter tail classes. With respect to the M&C classes of business we continue to write, we focus on artisan contractors and light manufacturers that present no significant durable products liability exposure.

      Our insurance policies provide coverage limits generally ranging from $25,000 to $1.0 million per occurrence, with the majority of our policies having limits between $500,000 and $1.0 million. Generally, through reinsurance, we are subject to the first $500,000 of an individual loss for the current accident year. Our general liability policies usually provide coverage for defense and related expenses in addition to per occurrence and aggregate policy limits. For certain products, defense expenses are included in the policy limits.
      Other Casualty Business. We also offer garage liability and commercial umbrella policies to supplement our commercial multi-peril and commercial general liability writings. On garage liability we write up to a maximum of $1.0 million per occurrence or accident. This product is only offered by surplus lines carriers. Commercial umbrella policies provide excess liability coverage above the limits of standard liability policies and may also provide coverage for risks not covered under standard liability policies. We write commercial umbrella insurance for limits up to $5.0 million total aggregate above the minimum underlying limits of $1.0 million per occurrence and $2.0 million aggregate. Although most of our umbrella and excess business is written to support our primary policies, we will occasionally accept other carriers as primary, provided they are rated “A-” or better by A.M. Best.
      Property Business. Following our management-led buyout in October 2000, we have increased our property gross written premiums as a percentage of our total property/casualty written premiums. For the nine months ended September 30, 2000, property business and casualty business accounted for 17.9% and 82.1%, respectively, of our total property/casualty gross written premiums. For the year ended December 31, 2004, 35.5% and 64.5% of our total property/casualty gross written premiums comprised property business and casualty business, respectively. Consistent with our focus on shorter tail casualty lines, we believe that the inherent short tail property business presents less rating and reserving risk to us. Our property business represents classes of business that were chronically under-priced by the standard market admitted insurers in the late 1990s and have since been pushed to the excess and surplus lines market. These classes include apartments, commercial buildings and low value dwellings
      Our commercial property lines provide coverage limits of up to $25.0 million, but the vast majority of our written premiums in 2004 were written at limits of less than $2.0 million. Through the use of reinsurance, we retain the first $500,000 of each individual loss for the current accident year.
      Package Business. We write commercial multi-peril policies that provide our insureds with commercial property and general liability coverages bundled together as a “package.” The targeted classes, limits and pricing on these policies are the same as if written separately.
      Other (Including Exited Lines) We write a limited amount of landfill and specialty surety bond business on a direct and assumed basis. As of December 31, 2004, these bonds are ceded through a 100% quota share reinsurance agreement with Evergreen. We continue to write surety business in order to maintain our U.S. Treasury Listing. We do not expect our surety segment to exceed 4% of our total gross written premium for any given year.
      In addition, in connection with our management-led buyout in October 2000, we changed our strategic direction to focus primarily on the excess and surplus lines and the exiting of certain unprofitable business. As a result, we exited the commercial automobile line in May 2000 and the workers’ compensation line effective as of January 1, 2002.

      We attempt to minimize catastrophic risk by diversifying in different geographical regions. Our primary catastrophic risk is structural property exposures as a result of hurricanes, tornados, hail storms, winter storms and freezing. We maintain property catastrophe coverage by evaluating the probable maximum loss using a catastrophe exposure model developed by independent experts. We do not write wind coverage in Florida or within two counties of the Gulf of Mexico and the eastern seaboard states.
Underwriting and Pricing
      We underwrite our commercial property/casualty business on a binding authority and a brokerage basis.
      Binding Authority. Binding authority business represents risks that may be quoted and bound with a policy subsequently issued on our behalf by our general agents. This business is produced in accordance with specific and detailed rules set forth in our Electronic Underwriting Manual (“EUM”) that is provided to our general agents. There are limited classes and no premium credits available to the general agency underwriter. We monitor the classes of business subject to agents’ binding authority, considering market conditions, competition, underwriting results and other factors and we frequently change these guidelines by amending our EUM.
      Our EUM provides that some prospective insureds must be submitted to our underwriters for specific approval prior to the agent quoting or binding the risk. The most frequent reason for this specific approval requirement is the size of the risk involved. Any prospective property risk with a total insured value (“TIV”) over $1.0 million is automatically required to be submitted for prior approval. Similarly, any prospective casualty risk with a premium of $25,000 or greater is required to be submitted for prior approval.
      The economics of the binding business are generally different than those of the brokerage business due to the differing characteristics of each type of business. It is important to provide binding authority for the less difficult binding classes because the binding book has greater persistency than the brokerage business and is less likely to be “shopped” at renewal as a result of our general agent’s authority to issue the policy immediately.
      Binding authority business accounted for 56.5% of our total core property/casualty gross written premiums for the year ended December 31, 2004. Our EUM outlines our risk eligibility, pricing, underwriting guidelines and policy issuance instructions. We monitor the underwriting quality of our business by re-underwriting each piece of business produced by our general agents in accordance with their underwriting authority.
      We provide additional incentives to our general agents to produce profitable business through a contingent profit commission structure that is tied directly to underwriting profitability. This contingent profit commission applies only to business produced pursuant to our general agents’ underwriting authority (i.e., binding business) where the agent plays a role in underwriting the risk. In addition, beginning in 2005, we are

Table of Contents

providing a bonus incentive to agents based the overall growth of the book of business that the agent places with us.
      Brokerage Business. Brokerage business represents risks that exceed the limits of underwriting authority that we are willing to grant to our general agents. Many of our brokerage accounts are classes of insurance that are not permitted to be written at all by our general agents pursuant to their binding authority. However, most of our brokerage business is produced on risks that produce individual TIV or premium above levels we believe prudent to allow for agency binding and issuance authority. For property business, any risk with a TIV over $1,000,000 is automatically classified as a brokerage account. For casualty business, the threshold is $25,000 in premium. If there is a package policy where either the property or casualty portion is indicated as a brokerage account, the entire account is classified as brokerage business. Commissions on brokerage policies are 3.5% lower than on binding contracts, and there is no contingent profit commission available to our general agents on brokerage business. Brokerage business accounted for approximately 43.5% of our total core property/casualty gross written premiums for the year ended December 31, 2004.
      Pricing. In the commercial property and casualty market, the rates and terms of coverage provided by property and casualty insurance carriers are frequently based on benchmarks and forms promulgated by the Insurance Services Office, also known as ISO. ISO makes available to its members advisory rating, statistical and actuarial services, policy language and other related services. ISO currently provides these services to more than 1,500 property and casualty insurance companies in the United States. One of the services that ISO provides is an actuarial-based estimate of the expected loss cost for risks in each of approximately 1,000 risk classifications. These benchmark loss costs reflect an analysis of the loss and allocated loss adjustment expenses on claims reported to ISO. ISO statistics, however, include only claims and policy information reported to ISO, and therefore do not reflect all of the loss experience for each class.
      We primarily use ISO loss costs as the foundation for establishing our rates for all lines of business. We then develop “loss cost multipliers,” or LCMs, which are designed to support our operating expenses, acquisition expenses and targeted return on equity. On our property business, we employ a proprietary class rating matrix that employs a series of ISO commercial fire rating schedule-based charges determined by construction, occupancy, protection and geographical concerns. We multiply our LCMs by ISO loss cost to produce our final rates. We also employ minimum premiums based on the limit and coverage provided that can only increase the effective rate. Our final rates are regionalized to incorporate variables such as historic loss experience, the types and lines of business written, competition and state regulatory considerations. For business that we write on an admitted, or licensed, basis, we must obtain advance regulatory approval of rates in a number of states. We do not provide our general agents with downward pricing flexibility on a per policy basis. All agency underwritten business is re-underwritten by our binding unit to check for mistakes or other results that may be inconsistent with the rules set forth in our EUM.
Marketing and Distribution
      As of December 31, 2004, we marketed our products through 104 agents, including 84 agents with binding authority. These agents maintain 117 offices in 35 states. This wholesale general agency force makes our products available to licensed retail agencies throughout the United States. We believe that our distribution network enables us to efficiently access at a relatively low fixed cost the numerous small markets our product offerings target. These general agents and their retail insurance agents and brokers have local market knowledge and expertise that enable us to more effectively access these markets. We generally confine our general agents marketing territory to three or fewer states.
      We strive to preserve each general agent’s franchise value with us in that general agent’s marketing territory. We seek to increase our written premiums with these general agents and to develop long-term, profitable relationships by providing a high level of service and support. For example, we try to respond to our general agents’ requests for quotes on their proposals within 48 hours. We believe that the performance of the business that we ultimately write is measurably improved when produced by general agents who have increased familiarity and experience with our underwriting requirements.

Claims Management and Administration
      Our approach to claims management is to:
  •  investigate reported incidents as soon as possible;
 
  •  select, manage and supervise all legal and adjustment aspects of the claim; and
 
  •  provide a high level of service and support to agents and insureds throughout the claims process.
Our general agents have no authority to settle claims or otherwise exercise control over the claims process. Our claims management staff supervises and processes all claims. Claims adjusters have reserving authority based upon their skill level and experience. We have a formal claims review process, and changes in loss and loss expense reserves on all claims valued greater than $25,000 are reviewed on a weekly basis by senior claims and underwriting management and the President of Century.
Loss and Loss Expense Reserves
      We are liable for loss and loss expense reserves under the terms of the insurance policies that we write. In many cases, several years may lapse between the occurrence of an insured loss, the reporting of the loss to us and our settlement of that loss. We reflect our liability for the ultimate payment of all incurred losses and loss expenses by establishing loss and loss expense reserves as balance sheet liabilities for both reported and unreported claims. We do not use discounting (recognition of the time value of money) in reporting our estimated reserves for losses and loss expenses.
      When a claim is reported, our claim department establishes a “case reserve” for the estimated amount of the ultimate payment within 90 days of the receipt of the claim. The estimate of the amount of the ultimate loss is based upon various factors such as:
  •  the type of loss;
 
  •  the jurisdiction of the occurrence;
 
  •  our knowledge of the circumstances surrounding the claim;
 
  •  the severity of injury or damage;
 
  •  the potential for covered loss; and
 
  •  policy provisions relating to the claim.
      In addition to case reserves, we establish reserves on an aggregate basis to provide for losses and loss expenses that have been incurred but not reported, commonly referred to as “IBNR.” Case reserves and IBNR comprise the total loss and loss expense reserves.
      Our internal actuaries apply multiple traditional actuarial techniques to compute loss and loss expense reserve estimates for claim liabilities other than construction defect. Each individual technique produces a unique loss and loss expense reserve estimate for the line being analyzed. The set of techniques applied together produces a range of loss and loss expense reserve estimates. From these estimates, the actuaries form a best estimate which considers the assumptions and factors discussed below that influence ultimate claim costs. For construction defect claim liabilities, our internal actuaries apply one actuarial technique, under various sets of assumptions, which considers the factors that influence ultimate claim costs as discussed below. The actuarial technique for construction defect claims includes several variables relating to the number of IBNR claims and the average cost per IBNR claim. In addition to computing best estimate parameter values for the actuarial projection, the actuaries also consider the impact on resulting IBNR related to reasonably foreseeable fluctuations in these variables.

      The actuarial techniques for computing loss and loss expense reserve estimates use the following factors, among others:
  •  our experience and the industry’s experience;
 
  •  historical trends in reserving patterns and loss payments;
 
  •  the impact of claim inflation;
 
  •  the pending level of unpaid claims;
 
  •  the cost of claim settlements;
 
  •  the line of business mix; and
 
  •  the environment in which property and casualty insurance companies operate.
      Although many factors influence the actual cost of claims and our corresponding reserve estimates, we do not measure and estimate values for all of these variables individually. This is due to the fact that many of the factors that are known to impact the cost of claims cannot be measured directly, such as the impact on claim costs due to economic inflation, coverage interpretations and jury determinations. In most instances, we rely on our historical experience or industry information to estimate values for the variables that are explicitly used in our reserve analyses. We assume that the historical effect of these unmeasured factors, which is embedded in our experience or industry experience, is representative of future effects of these factors. Where we have reason to expect a change in the effect of one of these factors, we perform analysis to quantify the necessary adjustments.
      We periodically review these estimates and, based on new developments and information, we include adjustments of the probable ultimate liability in operating results for the periods in which the adjustments are made. In general, our initial reserves are based upon the actuarial and underwriting data utilized to set pricing levels and are reviewed as additional information, including claims experience, becomes available. The establishment of loss and loss expense reserves makes no provision for the broadening of coverage by legislative action or judicial interpretation or for the extraordinary future emergence of new types of losses not sufficiently represented in our historical experience or which cannot yet be quantified. We regularly analyze our reserves and review our pricing and reserving methodologies so that future adjustments to prior year reserves can be minimized. However, given the complexity of this process, reserves will require continual updates and the ultimate liability may be higher or lower than previously indicated.
      Our Actuarial Unit has three actuaries, each of whom is a Fellow of the Casualty Actuarial Society and Member of the American Academy of Actuaries. The duties of the Actuarial Unit include:
  •  performing an actuarial analysis of loss and loss expense reserves on a quarterly basis;
 
  •  assisting our Underwriting Department in evaluating pricing adequacy;
 
  •  assisting our Loss Reserve Committee, which includes our Vice President and Chief Actuary, Senior Claims Officer, Chief Financial Officer (Chairman), Chief Operating Officer and the President of Century, in establishing management’s best estimate of loss and loss expense reserves; and
 
  •  working with our independent external actuary in the year-end loss and loss expense reserves statement of actuarial opinion process.
Due to the inherent uncertainty in estimating reserves for losses and loss expenses, there can be no assurance that the ultimate liability will not exceed amounts reserved, with a resulting adverse effect on our results of operations and financial condition. Based on the current assumptions used in calculating reserves, management believes our overall reserve levels at December 31, 2004 make a reasonable provision for our future obligations.

An explanation of significant components of loss and loss expense reserve development by segment (net of reinsurance, unless otherwise indicated) follows.
Property/ Casualty
      Casualty. Our changes in the reserve estimates related to prior accident years for the years ended December 31, 2004, 2003 and 2002 for the casualty lines resulted in increases in incurred losses and loss expenses of $12.8 million, $22.2 million, and $13.5 million respectively. A significant portion of our casualty reserves relate to construction defect claims in certain states. See “Business — General.” Starting with California in December 2000, we began to exit contractors’ liability business. By the end of the first quarter of 2001, we had significantly reduced our contractors’ liability underwriting in all states, and completely eliminated contractors’ liability underwriting in Arizona, California, Colorado, Hawaii, Louisiana, Nevada, New Jersey, North Carolina, Oregon, South Carolina and Washington. Reserves and claim frequency on this business may also be impacted by legislation recently enacted in California, which generally provides consumers who experience construction defects a method other than litigation to obtain reimbursement for construction defect repairs. This legislation may impact claim severity, frequency and length to settlement assumptions underlying our reserves. Accordingly, our ultimate liability may exceed or be less than current estimates due to this variable, among others.

Table of Contents

      Of our construction defect net loss and loss expense reserves at December 31, 2004, 61.0% was for incurred but not reported losses (which are referred to as IBNR) and 52.5% of our construction defect net loss and loss expense reserves at December 31, 2003 was for IBNR. As of December 31, 2004, we had 566 open claims relating to construction defects, compared to 597 open claims as of December 31, 2003. During 2004, 986 new claims were reported and 1,017 existing claims were settled or dismissed. Our net loss and loss expense reserves for construction defects as of December 31, 2004 were $19.0 million. The adverse development recognized in 2004 and 2003, related to construction defect was $8.3 million and $13.4 million, respectively. The re-estimation of construction defect reserves primarily affected the 1996 and 1997 accident years and the 1999 to 2001 accident years.
      In addition, during 2004 and 2003, we also experienced development above expectations on our non-construction defect casualty reserves for the 2000 to 2002 years that led to reassessments of the initial loss ratio expectations and the claim reporting and settlement patterns. The adverse development recognized in 2004 and 2003, related to our non-construction defect casualty reserves was $4.6 million and $8.8 million, respectively.
      As of December 31, 2004, the projected loss and loss expense ratios, after the effects of reinsurance, for the casualty lines were 48.9%, 44.0% and 57.8% for accident periods 2004, 2003, and 2002, respectively.
      Property. Our changes in estimate for the years ended December 31, 2004, 2003 and 2002 for the property lines resulted in increases (decreases) of ($3.2) million, $2.3 million and ($22,000), respectively. These amounts primarily relate to changes in the selected development patterns on all accident years, as the number of claims and claim severity exceeded expectations at December 31, 2002, and were below expectations at December 31, 2003 and 2001.
      As of December 31, 2004, the projected loss and loss expense ratios, after the effects of reinsurance, for the property lines were 58.8%, 50.3% and 57.2% for accident periods 2004, 2003 and 2002, respectively.
Other (Including Exited Lines)
      We began writing commercial automobile coverage for commercial vehicles and trucks in 1997. In 2000, we exited the commercial automobile line of business due to unsatisfactory underwriting results. At December 31, 2004, all of our net loss and loss expense reserves related to commercial automobile was for case reserves. At December 31, 2003, 0.6% of our commercial automobile net loss and loss expense reserves was for IBNR and 99.4% was for case reserves. As of December 31, 2004, we had 38 open claims relating to commercial automobile, compared to 63 open claims as of December 31, 2003. During 2004, eight new claims were reported and 33 existing claims were settled or dismissed. Our net loss and loss expense reserves for commercial automobile as of December 31, 2004 were $1.8 million.
      We offered workers’ compensation coverage from 1997 through January 2002. We exited this line of business beginning January 1, 2002 due to unsatisfactory underwriting results and the lack of availability of acceptable reinsurance. Until July 2000, we purchased 100% quota share reinsurance on this book of business. Beginning in 2000, we started to retain some risk. No new policies have been written since the first quarter of 2002. Of our net loss and loss expense reserves at December 31, 2004, 49.8% related to workers’ compensation claims IBNR, and 2.3% of our net loss and loss expense reserves at December 31, 2003 was for workers’ compensation IBNR. As of December 31, 2004, we had 257 open claims relating to workers’ compensation compared to 414 open claims as of December 31, 2003. During 2004, 13 new claims were reported, and 170 existing claims were settled or dismissed. Our net loss and loss expense reserves for workers’ compensation as of December 31, 2004 were $3.4 million.
      The table provided below presents the development of reserves, net of reinsurance, from 1995 through 2004. The top line of the table presents the reserves at the balance sheet date for each of the periods indicated. This represents the estimated amounts of loss and loss expenses for claims arising in the period 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 presents the re-estimated amount of the previously recorded reserves based on experience as of the end of each succeeding period, including cumulative payments made since the end of the respective

period. The estimate changes as more information becomes known about the payments, as well as the frequency and severity of claims for individual periods. Favorable loss development, shown as a cumulative redundancy in the table, exists when the original reserve estimate is greater than the re-estimated reserves. The lower portion of the table presents the cumulative amounts paid as of the end of each successive period with respect to those claims. 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 provided below, note that each amount entered incorporates the cumulative effects of all changes in amounts entered for prior periods. The table does not present accident or policy year development data. In addition, conditions and trends that have affected the development of liability in the past may not necessarily recur in the future.
