James River Group

Who We Are

James River is an insurance holding company that owns and manages specialty property/casualty insurance companies with the objective of consistently earning underwriting profits. We were founded in September 2002 and wrote our first insurance policy in July 2003. We currently underwrite in two specialty areas:

•  excess and surplus lines in 48 states and the District of Columbia; and
•  workers' compensation primarily for the residential construction industry in North Carolina.

Our underwriters evaluate and price each policy individually, and we do not extend underwriting or claims handling authority to third parties. For the year ended December 31, 2004, our first full year of insurance operations, we wrote $142.5 million in direct written premiums, earned net income of $8.8 million and had a combined ratio (a measure of underwriting profitability calculated by dividing the sum of losses incurred, including loss adjustment expenses, and other operating expenses by net earned premiums) of 90.1%. A combined ratio of less than 100% generally indicates profitable underwriting prior to the consideration of investment income.

The executives and professional investors who founded our company have significant experience managing, acquiring or investing in insurance operations. Key members of our management team, including J. Adam Abram, our President and Chief Executive Officer, five of our directors and a number of the managers in our excess and surplus lines business, were previously involved together at Front Royal, Inc., another insurance holding company with a similar business focus. Because we wrote our first policy in July 2003, we are not burdened by material loss exposures for years prior to 2003. We did not write any insurance during the 1990's when pricing was more competitive and policy terms were less restrictive than in the current environment. We craft our excess and surplus lines policy language to manage our exposure to expanding theories of legal liability like those which have given rise to claims for lead paint, asbestos, mold and construction defects.

Our Products

Our subsidiary James River Insurance Company writes excess and surplus lines insurance. Excess and surplus lines insurance covers risks that do not fit the underwriting criteria of standard carriers due, usually, to the perceived risk associated with aspects of the insured's business. In contrast to standard carriers that are required to be licensed in the state where the insurance is written, James River Insurance has significantly expanded regulatory freedom to craft policy terms and charge negotiated prices. Generally, James River Insurance offers more restrictive coverage at higher prices than would be offered by the standard market, which is necessary because insureds in the excess and surplus market are generally considered higher risk than those in the standard market. For the year ended December 31, 2004, James River Insurance had $133.4 million in direct written premiums.

Our subsidiary Stonewood Insurance Company writes workers' compensation insurance in North Carolina, primarily for the residential construction industry. Workers' compensation insurance provides coverage for the statutory obligations of employers to pay for medical care and lost wages for employees who are injured in the course of their employment. We focus on the residential construction industry because this hazardous class has relatively high premium rates and we believe we can successfully underwrite these accounts through proactive loss control. This approach requires us to rely on our underwriting and loss control staff to assess the risk of potential insureds. Stonewood Insurance was licensed in late 2003 and began writing business in January 2004. For the year ended December 31, 2004, Stonewood Insurance had $9.2 million in direct written premiums.

Both James River Insurance and Stonewood Insurance are rated "A−" (Excellent) by A.M. Best Company, Inc., a leading insurance rating agency, which we refer to in this prospectus as A.M. Best. "A−" (Excellent) is the fourth highest of 16 A.M. Best ratings. These ratings are based on matters of concern to policyholders but are not designed or intended for use by investors in evaluating our securities.

Our Approach to Our Business

We believe our approach will help us achieve our goal of delivering superior returns to our stockholders. This approach involves the following:

Generate Underwriting Profits.    We intend to generate underwriting profits by minimizing our underwriting expenses and focusing on underwriting specialty insurance risks where we can use our expertise to price and structure policies to minimize our claims expenses.

•  Operate at a Lower Expense Ratio Than Many of Our Competitors.    We believe that we are able to achieve a lower expense ratio than many of our competitors because of our assertive management of costs, including commissions. In 2004, our Excess and Surplus Insurance segment had a statutory expense ratio (a measure of our underwriting profitability calculated by dividing our underwriting expenses by net written premiums, in each case determined on a statutory accounting basis) of 19.95%. According to the 2004 edition of Best's Aggregates & Averages – Property/Casualty, from 1999 through 2003, which we believe is the latest data available, the United States excess and surplus lines sector had an average statutory expense ratio of 30.9%.
•  Focus on Specialty Insurance Markets.    By focusing on specialty markets in which our underwriters have particular expertise and in which we have fewer competitors than in standard markets, we have greater freedom to price and structure our products and to utilize loss control measures to target maximum profitability. For example, in our Excess and Surplus Insurance segment, we seek an underwriting profit by generally offering a combination of higher prices and more restrictive policy terms than standard carriers. Our insureds, on the other hand, generally present higher risk than that presented by the insureds of standard carriers.
•  Underwrite Each Risk Individually.    We believe our goal of earning underwriting profits is best accomplished through careful risk selection combined with a thoughtful approach to setting the terms and conditions of the policies for these risks. We individually underwrite each risk and do not extend underwriting authority to brokers, agents or other third parties. Our underwriting team leaders have an average of 27 years of insurance industry experience. A substantial portion of our underwriters' compensation is linked to the underwriting profit produced by the policies they underwrite. This approach has the potential drawback of requiring us to rely heavily on experienced underwriters who can tailor coverages and to be particularly careful in selecting the policies we bind. Our underwriters regularly interact with our claims personnel to aid in underwriting decisions and policy form development. In our Workers' Compensation Insurance segment, we supplement the underwriting process through on-site inspection of insureds and proactive loss control measures.

2




•  Use Timely and Accurate Data.    We design our internal processing and data collection systems to provide our management team with accurate and relevant information in real-time. Our data warehouse collects premium, commission and claims data, including detailed information regarding policy price, terms, conditions and the insured's business. This data allows us to analyze trends in our business, including results by individual agent or broker, underwriter and class of business. We rely on our technology systems in this process.
•  Actively Manage Claims.    We believe that actively managing our claims is an important aspect of keeping loss and loss adjustment expenses low and accurately setting reserves. We promptly and thoroughly investigate all claims, generally through direct contact with the insured and other affected parties. When we believe claims are not validly covered under the policy form, we vigorously contest payment and are willing to pursue prosecution for claims fraud.

Opportunistically Grow Our Business.    We plan to opportunistically grow our business in markets where we can use our specialized expertise to generate consistent underwriting profits.

•  Expand Existing Operations.    We intend to expand our existing insurance operations to increase our market share in our chosen markets. Both our Excess and Surplus Insurance and Workers' Compensation Insurance segments are relatively new, and we believe they can capture more market share. A potential drawback of our specialized approach is that we may be more vulnerable to adverse events that affect the excess and surplus lines and workers' compensation insurance business than companies that have more diversified business.
•  Excess and Surplus Insurance Segment.    We seek to grow the business of our Excess and Surplus Insurance segment by taking advantage of opportunities for enhanced product offerings, additional coverages, geographic expansion and increased penetration in our existing markets. We have expanded the Excess and Surplus Insurance segment from seven underwriting divisions at inception to ten divisions at December 31, 2004, added an additional underwriting division in May 2005 and anticipate adding another underwriting division in 2005. We continue to make selective broker appointments which helps drive our market penetration. In 2004, our Excess and Surplus Insurance segment wrote $133.4 million in direct written premiums. A.M. Best estimated total premiums in this market to be $32.8 billion in 2003.
•  Workers' Compensation Insurance Segment.    We seek to expand our Workers' Compensation Insurance segment by adding selected agents and achieving greater market penetration. Our Workers' Compensation Insurance segment wrote $9.2 million in direct written premiums in 2004, its first year of operation, and we estimate, based in part on 2001 data (the latest we believe to be available) from the North Carolina Rate Bureau, that the North Carolina workers' compensation market for the portions of the construction industry in which we compete is approximately $450 million in direct written premiums.
•  Acquire Additional Specialty Insurance Businesses.    We intend to pursue acquisitions of specialty insurance businesses which have particular expertise in operating profitably in their markets. Our management team has significant industry experience in acquisitions of insurance companies and managing general agencies.

Manage Specialized Insurance Operations on a Decentralized Basis.    Our holding company structure allows our specialized insurance operations to focus on achieving an underwriting profit in their markets. Our decentralized underwriting and claims handling personnel are able to respond effectively to changing conditions in the particular markets in which they operate. We handle capital raising, mergers and acquisitions, investor and rating agency relations, financial reporting and other support functions at the holding company level. This decentralized approach means our company must make special efforts to ensure the company is coordinated as a whole.

Manage Capital Actively.    We intend to expand our business and capital base to capitalize on opportunities to earn an underwriting profit, and reduce our business and capital base if attractive underwriting opportunities are not available. We expect to finance our future operations with a

3




combination of debt and equity and do not intend to raise or retain more capital than we believe we can profitably deploy in a reasonable time frame. We may not, however, always be able to raise capital when needed. Our ratings from A.M. Best are very important to us, and maintaining them will be a principal consideration in our decisions regarding capital.

Maintain a Strong Balance Sheet.    We intend to set reserves conservatively and monitor reinsurance recoverables exposure carefully in order to maintain a strong balance sheet. We focus on making our profits from underwriting and do not expect above-market returns or risks in our investment portfolio. As a consequence, our investment returns may not be as high as those earned by some of our competitors. Our balance sheet is not burdened with material legacy liabilities related to loss exposures for years prior to 2003.

Our Challenges

As part of your evaluation of our business, you should take into account the challenges we face in implementing our strategies, including but not limited to the following:

A Downgrade in Our A.M. Best Rating Would Negatively Affect Our Business.    We believe that the A.M. Best rating of "A−" (Excellent) of our insurance subsidiaries has a significant influence on our business and that many brokers, agents and customers would not place business with us if we experienced a downgrade in our rating. As a result, a downgrade in our rating could cause a substantial reduction in the number of policies we write, which would have a material adverse effect on our results of operations and our financial position.

Changes in Our Operating Environment May Adversely Affect Our Performance.    Our operating results may fluctuate significantly quarter to quarter and year to year due to various factors generally out of our control, including changes in competition, market conditions, catastrophe losses, severe weather conditions, general economic conditions (including interest rate changes), court decisions, legislative initiatives, frequency of litigation and the size of judgments.

The Failure of Any of Our Loss Limitations or Exclusions Could Harm Our Business.    Various provisions of our excess and surplus lines policies, such as limitations or exclusions from coverage, have been negotiated to limit our risks and may not be enforceable in the manner we intend. Court decisions, legislation or regulatory actions could interpret or regulate the use of such endorsements and limitations in a way that would adversely effect our loss experience, which could have a material adverse effect on our financial condition or results of operations.

We Rely on a Select Group of Brokers and Agents To Distribute Our Products.    Two brokers accounted for approximately 34.9% of 2004 direct written premiums for James River Insurance, and one agent accounted for approximately 11.0% of 2004 direct written premiums for Stonewood Insurance. These relationships could terminate or fail to be profitable in the future, which could have a material adverse effect on us.

Our Reinsurers May Not Pay Our Claims in a Timely Fashion.    We cede a part of the policy risk we assume to reinsurers in exchange for part of the premium we receive in connection with the risk. If our reinsurers do not pay claims made by us on a timely basis, or they fail to pay some or all of these claims, we will be responsible for additional payments to our policyholders. This would increase our costs and could have a material adverse effect on our business.

We Are Dependent on Our Key Employees.    Because we are dependent on certain key executives, the loss of any of these executives or our inability to retain other key personnel could adversely affect our business.

Our Premium and Loss Reserves May Be Inadequate to Cover Our Actual Losses.    If we fail to accurately assess the risks associated with the business we insure, we may fail to establish appropriate premium rates, and our reserves for unpaid losses and loss adjustment expenses (which we refer to as loss reserves) may be inadequate to cover our actual losses. Our loss reserves are estimates and are inherently

4




uncertain. If our loss reserves are inadequate to cover our actual losses and loss adjustment expenses, any changes in our estimates will be reflected in our results of operations during the period in which the changes are made, with increases in our loss reserves resulting in a reduction to our earnings.

We Have a Short Operating History.    We have completed only six quarters of operations and our historical financial results may not accurately indicate our future performance.

Our Business is Subject to Extensive Regulation.    Our business is subject to extensive regulation by applicable federal and state agencies in the jurisdictions in which we operate. The extensive regulation or changes in the regulation governing our business may affect the cost or demand for our products and may limit our ability to obtain rate increases or take other actions, including those that relate to the terms of our coverage, that we may wish to take to increase our profitability.

(4) The loss ratio is the ratio, expressed as a percentage, of losses and loss adjustment expenses to net earned premiums, net of the effects of reinsurance.
(5) The expense ratio is the ratio, expressed as a percentage, of other operating expenses to net earned premiums.
(6) The combined ratio is the sum of the loss ratio and the expense ratio.
(7) Return on average stockholders' equity is the ratio, expressed as a percentage, of net income (loss) to the average of the beginning of period and end of period total stockholders' equity. The calculations for the three months ended March 31, 2005 and 2004 use annualized net income as the numerator in the calculation. Annualized results are not necessarily indicative of our actual results for the full year.
(8) The debt to total capitalization ratio is the ratio, expressed as a percentage, of total indebtedness for borrowed money to the sum of total indebtedness for borrowed money and stockholders' equity.
(9) The net written premiums to surplus ratio is the ratio of net written premiums to statutory-basis capital and surplus. We believe this measure is useful in evaluating our insurance subsidiaries' operating leverage. It may not be comparable to the definition of net written premiums to surplus ratio for other companies. The calculations for the three months ended March 31, 2005 and 2004 use annualized net written premiums as the numerator in the calculation. Annualized results are not necessarily indicative of our actual results for the full year.

Income before tax equaled net income for the three and six months ended June 30, 2004 because we used net operating loss carryforwards to fully offset our taxable income for those periods. We did not have net operating loss carryforwards available to offset our taxable income for the three and six months ended June 30, 2005.

We entered into a quota share reinsurance contract effective January 1, 2005 that transfers a portion of the risk related to certain property/casualty business written by James River Insurance in 2005 to reinsurers in exchange for a portion of our direct written premiums on that business. See "Management's Discussion and Analysis of Financial Condition and Results of Operations — Overview". For the three months ended June 30, 2005, ceded earned premiums related to this quota share treaty were $8.5 million, ceded losses and loss adjustment expenses were $5.8 million and our reinsurance ceding commission was $2.2 million. For the six months ended June 30, 2005, ceded earned premiums related to this quota share treaty were $16.0 million, ceded losses and loss adjustment expenses were $11.1 million and our reinsurance ceding commission was $4.1 million.

Operating results for the three and six months ended June 30, 2005 benefited from $457,000 and $2.8 million, respectively, of favorable reserve development on the direct business that we wrote related to prior accident years. The impact of our share of the operating results related to our participation in the involuntary workers' compensation pool for North Carolina was a reduction to net income of $174,000 for the three months and six months ended June 30, 2005, and included $709,000 of incurred losses on our share of the involuntary pool's 2004 accident year results. A change in estimate related to the premium earned in the Workers' Compensation Insurance segment as a result of the payroll audit process resulted in an increase in net income of $272,000 for the three months and six months ended June 30, 2005.

Direct written premiums for the Excess and Surplus Insurance segment were $91.2 million for the six months ended June 30, 2005 compared to $51.1 million for the six months ended June 30, 2004. Direct written premiums for the Workers' Compensation Insurance segment were $13.6 million for the six months ended June 30, 2005 compared to $2.4 million for the six months ended June 30, 2004. The combined ratio for the Excess and Surplus Insurance segment for the six months ended June 30, 2005 was 75.1% compared to 88.6% for the six months ended June 30, 2004. The combined ratio for the Workers' Compensation Insurance segment for the six months ended June 30, 2005 was 92.9% compared to 230% for the six months ended June 30, 2004.

Return on average stockholders' equity is the ratio, expressed as a precentage, of net income (loss) to the average of the beginning of period and end of period total stockholders' equity. The calculations for the three and six month periods ended June 30, 2005 and 2004 use annualized net income as the numerator in the calculation. Annualized results are not necessarily indicative of our actual results for the full year.

RISK FACTORS

Investing in our common stock involves a high degree of risk. Before you invest in our common stock, you should carefully consider each of the following risks and cautionary statements, together with the other information contained in this prospectus. If any of the events described in the following risks actually occurs, our business, financial condition or results of operations may suffer. As a result, the trading price of our common stock could decline, and you could lose all or a substantial portion of your investment.

Risks Related To Our Business

  A decline in our financial strength rating may result in a reduction of new or renewal business.

Each of our insurance subsidiaries currently is rated "A−" (Excellent) by A.M. Best, which is the fourth highest of 16 A.M. Best ratings. A.M. Best assigns ratings that are intended to provide an independent opinion of an insurance company's ability to meet its obligations to policyholders and is not an evaluation directed to investors. A.M. Best focuses on balance sheet strength (including capital adequacy, and loss and loss expense reserve adequacy), operating performance and business profile. A reduction in our performance in these criteria could result in a downgrade of our rating. A downgrade of this rating could cause our current and future brokers and agents, retail brokers and insureds to choose other, more highly rated competitors. A downgrade of this rating could also increase the cost or reduce the availability of reinsurance to us.

  The failure of any of the loss limitations or exclusions we employ, or changes in other claim or coverage issues, could have a material adverse effect on our financial condition or our results of operations.

Various provisions of our policies, such as limitations or exclusions from coverage or choice of forum, which have been negotiated to limit our risks, may not be enforceable in the manner we intend. At the present time, we employ a variety of endorsements to our policies that limit exposure to known risks. As industry practices and legal, judicial, social and other conditions change, unexpected and unintended issues related to claims and coverage may emerge. These issues may adversely affect our business by either extending coverage beyond our underwriting intent or by increasing the size or number of claims.

In addition, we craft our excess and surplus lines policy language to manage our exposure to expanding theories of legal liability like those which have given rise to claims for lead paint, asbestos, mold and construction defects. Many of the policies we issue also include conditions requiring the prompt reporting of claims to us and our right to decline coverage in the event of a violation of that condition, In addition, many of our policies limit the period during which a policyholder may bring a claim under the policy, which in many cases is shorter than the statutory period under which such claims can be brought against our policyholders. While these exclusions and limitations help us assess and reduce our loss exposure and help eliminate known exposures to certain risks, it is possible that a court or regulatory authority could nullify or void an exclusion or legislation could be enacted modifying or barring the use of such endorsements and limitations. This could result in higher than anticipated losses and loss adjustment expenses which could have a material adverse effect on our financial condition or results of operations. In some instances, these changes may not become apparent until some time after we have issued insurance policies that are affected by the changes. As a result, the full extent of liability under our insurance contracts may not be known for many years after a contract is issued.

  We distribute our products through a select group of brokers and agents, three of which account for a significant part of our business, and there can be no assurance that such relationships will continue.

We distribute our products through a select group of brokers and agents. For the year ended December 31, 2004, 34.9% of James River Insurance's direct written premiums were distributed through two brokers, CRC Insurance Services, Inc. and Swett & Crawford, and approximately 11.0% of Stonewood Insurance's direct written premiums were distributed through one agent, SIA Group, Inc. Because our agreements with our agents and brokers do not require mimumum premium volumes and are terminable upon 30 or 60 days notice, we cannot assure you that such relationships will continue. If they do continue, it is possible they may not be profitable for us. The termination of our relationship with one or more of these brokers or agents could result in lower direct written premiums and have a material adverse effect on us.

11




  We may not be successful in reducing our risk through reinsurance arrangements and our reinsurers may not pay claims made by us in a timely fashion.

We purchase reinsurance by transferring part of the risk we have assumed (known as ceding) to reinsurers in exchange for part of the premium we receive in connection with the risk. Ceded premiums amounted to 15.7% of our direct written premiums in 2004. The availability, cost and structure of reinsurance protection are subject to changing market conditions, which are outside our control. If we are not able to obtain reinsurance protection on favorable terms, or at all, our potential losses could exceed our ability to pay and our business, financial condition or results of operations could suffer. Although reinsurance makes the reinsurer liable to us to the extent the risk is transferred or ceded to the reinsurer, it does not relieve us (the reinsured) of our liability to our policyholders. Accordingly, we bear risk with respect to our reinsurers. That is, our reinsurers may not pay claims made by us on a timely basis, or they may not pay some or all of these claims. Either of these events would increase our costs and could have a material adverse effect on our business. As of December 31, 2004, we had $15.2 million of reinsurance recoverable on unpaid losses and no reinsurance recoverable on paid losses.

  If we lose key personnel or are unable to recruit qualified personnel, our ability to implement our business strategies could be delayed or hindered.

Our future success will depend, in part, upon the efforts of our executive officers and other key personnel, including J. Adam Abram, President and Chief Executive Officer; Michael T. Oakes, Executive Vice President and Chief Financial Officer; Michael E. Crow, Senior Vice President—Finance and Chief Accounting Officer; Michael P. Kehoe, President and Chief Executive Officer of James River Management Company, Inc.; and C. Kenneth Mitchell, President and Chief Executive Officer of Stonewood Insurance Management Company, Inc. The loss of any of these officers or other key personnel could prevent us from fully implementing our business strategies and materially and adversely affect our business, financial condition and results of operations. We have employment agreements with four of our executive officers. We do not have key person insurance on the lives of any of our key management personnel. As we continue to grow, we will need to recruit and retain additional qualified management personnel, but we may not be able to do so. Our ability to recruit and retain such personnel will depend upon a number of factors, such as our results of operations, prospects and the level of competition then prevailing in the market for qualified personnel.

  Our actual incurred losses may be greater than our loss and loss adjustment expense reserves, which could have a material adverse effect on our financial condition and results of operations.

We are liable for losses and loss adjustment expenses under the terms of the insurance policies we underwrite. In many cases, several years may elapse between the occurrence of an insured loss, the reporting of the loss to us and our payment of the loss. We establish loss and loss adjustment expense reserves for the ultimate payment of all losses and loss adjustment expenses incurred. We estimate the reserve for losses and loss adjustment expenses using individual case-basis valuations of reported claims. We also use statistical analyses to estimate the cost of losses that have been incurred but not reported to us. These estimates are based on historical information and on estimates of future trends that may affect the frequency of claims and changes in the average cost of claims that may arise in the future. They are by their nature imprecise, and our ultimate losses and loss adjustment expenses may vary from established reserves. If any of our reserves should prove to be inadequate, we will be required to increase reserves resulting in a reduction in our net income and stockholders' equity in the period in which the deficiency is identified. Future loss experience substantially in excess of established reserves could also have a material effect on future earnings and liquidity and our financial rating.

Furthermore, factors that are difficult to predict, such as:

•  claims inflation,
•  claims development patterns,
•  legislative activity,
•  social and economic patterns and
•  litigation and regulatory trends

12




may have a substantial impact on our future losses and loss adjustment expenses. As of December 31, 2004, unpaid loss and loss adjustment expense reserves (net of reserves ceded to our reinsurers) were $47.0 million.

  Since we have a limited operating history, it is difficult to predict our future performance.

James River was organized in September 2002 and formed or acquired its two insurance subsidiaries in 2003. James River Insurance wrote its first policy effective July 1, 2003. Stonewood Insurance commenced writing insurance as of January 1, 2004. We therefore have limited operating and financial history available to help you evaluate our past performance or to make a decision about an investment in our common stock. In addition, because we focus our efforts on certain specialized sectors of the insurance market, and because we do not have an extensive claims history to date, our limited historical financial results may not accurately predict our future performance. Moreover, companies in their initial stages of development present substantial business and financial risks and may suffer significant losses. For example, early stage companies must generally develop business relationships, establish operating procedures, hire staff, install information and other management systems, establish facilities and obtain licenses in order to conduct their intended business activities. They are not always able to find the necessary resources at a reasonable cost, or at all. As a result of the risks specific to our business and those associated with new companies in general, it is possible that we may not be successful in implementing our business strategy. You should carefully consider our prospects in light of the risks and difficulties frequently encountered by early stage companies with limited operating histories.

  We are subject to extensive regulation, which may adversely affect our ability to achieve our business objectives. In addition, if we fail to comply with these regulations, we may be subject to penalties, including fines and suspensions, which may adversely affect our financial condition and results of operations.

Our subsidiaries are subject to extensive regulation, primarily by Ohio, the domiciliary state for James River Insurance, and North Carolina, the domiciliary state for Stonewood Insurance, and to a lesser degree, the other states in which we operate. Most insurance regulations are designed to protect the interests of insurance policyholders, as opposed to the interests of stockholders. These regulations generally are administered by a department of insurance in each state and relate to, among other things, authorizations to write excess and surplus lines of business, capital and surplus requirements, rate and form approvals, investment, underwriting limitations, affiliate transactions, dividend limitations, changes in control, solvency and a variety of other financial and non-financial aspects of our business. Significant changes in these laws and regulations could further limit our discretion or make it more expensive to conduct our business. State insurance departments also conduct periodic examinations of the affairs of insurance companies and require the filing of annual and other reports relating to financial condition, holding company issues and other matters. These regulatory requirements may impose timing and expense constraints that could adversely affect our ability to achieve some or all of our business objectives.

In addition, regulatory authorities have broad discretion to deny or revoke licenses for various reasons, including the violation of regulations. In some instances, where there is uncertainty as to applicability, we follow practices based on our interpretations of regulations or practices that we believe generally to be followed by the industry. These practices may turn out to be different from the interpretations of regulatory authorities. If we do not have the requisite licenses and approvals or do not comply with applicable regulatory requirements, insurance regulatory authorities could preclude or temporarily suspend us from carrying on some or all of our activities or otherwise penalize us. This could adversely affect our ability to operate our business. Further, changes in the level of regulation of the insurance industry or changes in laws or regulations themselves or interpretations by regulatory authorities could interfere with our operations and require us to bear additional costs of compliance, which could adversely affect our ability to operate our business.

The National Association of Insurance Commissioners has adopted a system to test the adequacy of statutory capital, known as "risk-based capital." This system establishes the minimum amount of risk-based capital necessary for a company to support its overall business operations. It identifies property/casualty insurers that may be inadequately capitalized by looking at certain inherent risks of

13




each insurer's assets and liabilities and its mix of net written premiums. Insurers falling below a calculated threshold may be subject to varying degrees of regulatory action, including supervision, rehabilitation or liquidation. Failure to maintain our risk-based capital at the required levels could adversely affect the ability of our insurance subsidiaries to maintain regulatory authority to conduct our business.

  Stonewood Insurance's business is heavily concentrated in workers' compensation insurance for the residential construction industry in North Carolina.

Stonewood Insurance's business is heavily concentrated in workers' compensation insurance in North Carolina and is further concentrated in the residential construction business. This makes Stonewood Insurance vulnerable to changes affecting the economy of North Carolina and in particular the residential construction business in North Carolina. By concentrating a substantial portion of its business in construction operations, Stonewood Insurance is exposed to substantial losses due to accidents and occupational hazards. We attempt to moderate these risks by the purchase of reinsurance and by underwriting and pricing accounts with these risks in mind. However, there can be no assurance that these precautions are adequate and that we will not be exposed to greater than anticipated losses arising from the hazardous nature of the business conducted by its insureds.

  We may require additional capital in the future, which may not be available or only available on unfavorable terms.

Our future capital requirements depend on many factors, including our ability to write new business successfully and to establish premium rates and reserves at levels sufficient to cover losses. To the extent that the funds generated by this offering are insufficient to fund future operating requirements and/or cover claim losses, we may need to raise additional funds through financings or curtail our growth. Based on our current operating plan, we believe that the net proceeds to us from this offering, together with our anticipated retained earnings, will support our operations through 2006 without the need to raise additional capital. However, we cannot provide any assurance in that regard, since many factors will affect our capital needs and their amount and timing, including our growth and profitability, our claims experience, and the availability of reinsurance, as well as possible acquisition opportunities, market disruptions and other unforeseeable developments. If we have to raise additional capital, equity or debt financing may not be available at all or may be available only on terms that are not favorable to us. In the case of equity financings, dilution to our stockholders could result. In any case, such securities may have rights, preferences and privileges that are senior to those of the shares offered hereby. In the case of debt financings, we may be subject to covenants that restrict our ability to freely operate our business. If we cannot obtain adequate capital on favorable terms or at all, we may not have sufficient funds to implement our operating plans and our business, financial condition or results of operations could be materially adversely affected.

  Our investment results and, therefore, our results and operations and financial condition may be impacted by changes in the business, financial condition or operating results of the entities in which we invest, as well as changes in interest rates, government monetary policies, general economic conditions and overall capital market conditions.

Our results of operations depend, in part, on the performance of our invested assets. Fluctuations in interest rates affect our returns on, and the fair value of, fixed-income securities. Unrealized gains and losses on fixed-income securities are recognized in accumulated other comprehensive income, net of taxes and minority interest, and increase or decrease our stockholders' equity. Interest rates in the United States are currently low relative to historical levels. An increase in interest rates could reduce the fair value of our investments in fixed-income securities. In addition, defaults by third parties who fail to pay or perform obligations could reduce our investment income and realized investment gains and could result in investment losses in our portfolio.

We had fixed-income and equity investments (consisting of a bond mutual fund) with a fair value of $175.0 million as of December 31, 2004 that are subject to:

•  credit risk, which is the risk that our invested assets will decrease in value due to unfavorable changes in the financial prospects or a downgrade in the credit rating of an entity in which we have invested;

14




•  equity price risk, which is the risk that we will incur economic loss due to a decline in the bond mutual fund share price; and
•  interest rate risk, which is the risk that our invested assets may decrease in value due to changes in interest rates.

Our fixed-income investment portfolio includes mortgage-backed securities. As of December 31, 2004, mortgage-backed securities constituted 18.1% of our fixed maturity securities. As with other fixed-income securities, the fair value of these securities fluctuates depending on market and other general economic conditions and the interest rate environment. Changes in interest rates can expose us to prepayment risks on these investments. In periods of declining interest rates, mortgage prepayments generally increase and mortgage-backed securities and other asset-backed securities are paid more quickly, requiring us to reinvest the proceeds at the then current market rates. Conversely, during periods of rising interest rates, the rate of prepayment generally slows. Mortgage-backed securities that have an amortized cost that is less than par (i.e. purchased at a discount) may incur a decrease in yield as a result of a slower rate of prepayment.

Our equity portfolio totaled $2.3 million as of December 31, 2004, which is invested in one bond mutual fund. The bond mutual fund in which we invest is highly diversified, and all of the securities in its portfolio are rated "AAA" by Standard & Poor's Rating Services, a division of The McGraw Hill Companies, Inc., which we refer to in this prospectus as Standard & Poor's, or received an equivalent rating from another nationally recognized rating agency. The fund's portfolio has an average duration of less than one year.

Since the end of 2002, the United States financial markets have experienced a high degree of volatility in interest rates, which affect the value of our fixed-income securities. As of December 31, 2004, our investment portfolio had a net unrealized investment loss, before the effect of income taxes, of $168,000.

  We rely on our information technology and telecommunication systems, and the failure of these systems could materially and adversely affect our business.

Our business is highly dependent upon the successful and uninterrupted functioning of our information technology and telecommunications systems. We rely on these systems to process new and renewal business, provide customer service, make claims payments and facilitate collections and cancellations. These systems also enable us to perform actuarial and other modeling functions necessary for underwriting and rate development. The failure of these systems, or the termination of a third-party software license upon which any of these systems is based, could interrupt our operations or materially impact our ability to evaluate and write new business. Because our information technology and telecommunications systems interface with and depend on third-party systems, we could experience service denials if demand for such services exceeds capacity or such third-party systems fail or experience interruptions. If sustained or repeated, a system failure or service denial could result in a deterioration of our ability to write and process new and renewal business and provide customer service or compromise our ability to pay claims in a timely manner. This could result in a material adverse effect on our business.

  Our growth may be dependent upon our successful acquisitions of other insurance businesses.

Following the offering, we will continue to pursue acquisitions of specialty insurance businesses that can be acquired on acceptable terms. Some of these acquisitions could be material in size and scope. Our future growth may depend, in part, upon the successful implementation of this strategy. While we will continually be searching for acquisition opportunities, there can be no assurance that we will be successful in identifying suitable acquisitions. If any potential acquisition opportunities are identified, there can be no assurance that we will consummate such acquisitions, or, if any such acquisition does occur, that it will be successful in enhancing our business, be accretive to either our profitability or book value or generate an underwriting profit. We may in the future face increased competition for acquisition opportunities which may inhibit our ability to consummate suitable acquisitions. In addition, to the extent that our acquisition strategy results in the acquisition of businesses, such acquisitions could pose a number of special risks, including the diversion of management's attention, the unsuccessful integration of the operations and personnel of the acquired companies, adverse short-term effects on reported operating results, the impairment of acquired intangible assets and the loss of key employees.

15




We may, in the future, issue additional common stock in connection with one or more acquisitions, which may dilute our stockholders, including the investors in this offering. Alternatively, we may issue debt, which could limit our future financial flexibility. Additionally, with respect to future acquisitions, our stockholders may not have an opportunity to review the financial statements of the entity being acquired or to vote on such acquisitions.

  If North Carolina drastically increases the assessments Stonewood Insurance is required to pay, our results of operations and financial condition will suffer.

Stonewood Insurance, our admitted insurance subsidiary, is subject to assessments in North Carolina, its domiciliary state, for various purposes, including the provision of funds necessary to fund the operations of the North Carolina insurance department and the state fund that pays covered claims under certain policies provided by impaired, insolvent or failed insurance companies. These assessments are generally set based on an insurer's percentage of the total premiums written in the insurer's state within a particular line of business. As Stonewood Insurance grows, our share of any assessments may increase. However, we cannot predict with certainty the amount of future assessments because they depend on factors outside our control, such as insolvencies of other insurance companies. Significant assessments could result in higher than expected operating expenses and have a material adverse effect on our financial condition or results of operations.

  Our reliance on brokers and agents subjects us to their credit risk.

With respect to the premiums produced by our brokers and agents, certain premiums from the policyholders are collected directly by the brokers or agents and forwarded to our insurance subsidiaries. In certain jurisdictions, when the insured pays premiums for these policies to brokers or agents for payment over to our insurance subsidiaries, the premiums might be considered to have been paid under applicable insurance laws and regulations and the insured will no longer be liable to us for those amounts, whether or not we have actually received the premiums from the broker or agent. Consequently, we assume a degree of credit risk associated with brokers and agents. Although brokers' and agents' failures to remit premiums to us have not had a material adverse effect on us to date, there may be instances where brokers and agents collect premium but do not remit it to us and we may be nonetheless required under applicable law to provide the coverage set forth in the policy despite the absence of premium. Because the possibility of these events is dependent in large part upon the financial condition and internal operations of our brokers and agents, which in most cases are not public information, we are not able to quantify the exposure presented by this risk. If we are unable to collect premiums from our brokers and agents in the future, our underwriting profits may decline and our financial condition and results of operations could be materially and adversely affected.

Risks Related to Our Industry

  Our business is cyclical in nature, which may affect our financial performance.

Historically, the financial performance of the property/casualty insurance industry has tended to fluctuate in cyclical periods of price competition and excess capacity (known as a soft market) followed by periods of high premium rates and shortages of underwriting capacity (known as a hard market). Although an individual insurance company's financial performance is dependent on its own specific business characteristics, the profitability of most property/casualty insurance companies tends to follow this cyclical market pattern. Further, this cyclical market pattern can be more pronounced in the excess and surplus market than in the standard insurance market. When the standard insurance market hardens, the excess and surplus market hardens, and growth in the excess and surplus market can be significantly more rapid than growth in the standard insurance market. Similarly, when conditions begin to soften, many customers that were previously driven into the excess and surplus market may return to the admitted market, exacerbating the effects of rate decreases. Beginning in 2000 and accelerating in 2001, the property/casualty insurance industry has been experiencing a market reflecting increasing rates, more restrictive coverage terms and more conservative risk selection. We believe these trends slowed beginning in 2004 and that the current insurance market is becoming generally more competitive in terms of pricing, policy terms and conditions. Since this cyclicality is due in large part to the actions of our competitors and

16




general economic factors, we cannot predict the timing or duration of changes in the market cycle. These cyclical patterns cause our revenues and net income to fluctuate, which may cause the price of our common stock to be volatile.

  If we are not able to renew our existing reinsurance or obtain new reinsurance, either our net exposure would increase or we would have to reduce the level of our underwriting commitment.

We currently purchase excess of loss reinsurance to stop our loss from a single occurrence on any one coverage part from any one policy. For our excess casualty and workers' compensation lines of business, we retain $500,000 of loss. For our workers' compensation line, we also retain the risk of loss for claims above a $20.0 million limit and $10.0 million for any one life. For our property and primary casualty lines of business, we retain $1.0 million in loss. Further, we purchase catastrophe reinsurance to cover losses arising from any single occurrence, regardless of how many policyholders are involved or the extent of their loss, from $2.0 million per occurrence up to $7.0 million per occurrence. However, we may choose in the future to re-evaluate the use of reinsurance to increase, decrease or eliminate the amount of liability we cede to reinsurers, depending upon the cost and availability of reinsurance.

Market conditions beyond our control determine the availability and cost of the reinsurance protection that we purchase. The reinsurance market has changed dramatically over the past few years as a result of inadequate pricing, poor underwriting and the significant losses incurred as a consequence of the terrorist attacks on September 11, 2001. As a result, reinsurers have exited some lines of business, reduced available capacity and implemented provisions in their contracts designed to reduce their exposure to loss. In addition, the historical results of reinsurance programs and the availability of capital also affect the availability of reinsurance. Our reinsurance facilities generally are subject to annual renewal. We cannot provide any assurance that we will be able to maintain our current reinsurance facilities or that we will be able to obtain other reinsurance facilities in adequate amounts and at favorable rates. If we are unable to renew our expiring contracts or to make new arrangements, either our net exposures would increase, which could increase our costs, or, if we were unwilling to bear an increase in net exposures, we would have to reduce the level of our underwriting commitments, especially catastrophe exposed risks, which would reduce our revenues.

  We compete with a large number of companies in the insurance industry for underwriting revenues.

We compete with a large number of other companies in our selected lines of business. Our principal competitors in the excess and surplus lines sector are Scottsdale Insurance Company (Nationwide Mutual Insurance Company), Markel Corporation, Burlington Insurance Group, Admiral Insurance Company (W. R. Berkley Corporation), Colony Insurance Company (The Argonaut Group) and RLI Corp., and in the workers' compensation insurance sector are Builders Mutual Insurance Company, Key Risk (W. R. Berkley Corporation) and Amerisure. We face competition both from specialty insurance companies, underwriting agencies and intermediaries, as well as diversified financial services companies that are significantly larger than we are and that have significantly greater financial, marketing, management and other resources than we do. Some of these competitors also have significantly greater experience and market recognition than we do. Larger carriers may have lower expense ratios, allowing them to price their products more competitively than us. We may incur increased costs in competing for underwriting revenues. If we are unable to compete effectively in the markets in which we operate or to expand our operations into new markets, our underwriting revenues and net income may decline.

A number of new, proposed or potential legislative and industry developments could further increase competition in our industry. These developments include:

•  an increase in capital-raising by companies in our lines of business, which could result in new entrants to our markets and an excess of capital in the industry;
•  programs in which state-sponsored entities provide property insurance in catastrophe prone areas or other "alternative markets" types of coverage;
•  changing practices caused by the internet, which may lead to greater competition in the insurance business; and
•  consolidation in the insurance industry, which could lead to lower margins for us.

17




New competition from these developments could cause the supply and/or demand for insurance or reinsurance to change, which could affect our ability to price our products at attractive rates and thereby affect our underwriting results. In addition, deregulation of commercial lines insurance has been adopted in many states and may be adopted in others. In some states, the deregulation of commercial lines generally enables admitted insurers to underwrite certain commercial property/casualty risks without the necessity of obtaining prior approval for rates and/or forms, although the content of policy forms is still regulated. In others states, the terms and conditions of commercial insurance policy forms have been deregulated. The deregulation of commercial lines may permit risks that would not otherwise be considered attractive by standard market carriers to be underwritten by such carriers using forms and rates that are attractive to them. Although no assurance can be given that further deregulation will occur, the extent to which it may occur or the form it will take, it is possible that deregulation of commercial lines insurance will increase competition in our markets, which could reduce our written premiums or make our products less profitable to us and adversely affect our results of operations and financial position.

We also may compete with new entrants in the future. Competition is based on many factors, including:

•  the perceived market strength of the insurer;
•  pricing and other terms and conditions;
•  services provided;
•  the speed of claims payment;
•  the reputation and experience of the insurer; and
•  ratings assigned by independent rating organizations such as A.M. Best.

Ultimately, this competition could affect our ability to attract business at premium rates that are likely to generate underwriting profits.

  As a holding company, we are dependent on the results of operations of our insurance subsidiaries and are likely to rely on the regulatory and financial capacity of our subsidiaries to pay dividends to us. The domiciliary states of our insurance subsidiaries limit the aggregate amount of dividends our subsidiaries may pay to us in any twelve-month period, thereby limiting our funds to pay expenses and dividends.

We are an insurance holding company and our principal asset is the shares we hold in our subsidiaries. Payments from our insurance company subsidiaries pursuant to management agreements and tax sharing agreements are our primary source of funds to pay holding company expenses. We anticipate that such payments, together with dividends paid to us by our subsidiaries, will be the primary source of funds for our holding company following this offering. The payment of dividends by our subsidiaries to us is limited by statute. In general, these restrictions limit the aggregate amount of dividends or other distributions that our subsidiaries may declare or pay within any 12 month period without advance regulatory approval. In Ohio, the domiciliary state of James River Insurance, this limitation is the greater of statutory net income for the preceding calendar year or 10% of the statutory surplus at the end of the preceding calendar year, and dividends may be paid only out of James River Insurance's earned surplus. In North Carolina, the domiciliary state of Stonewood Insurance, this limitation is the lesser of statutory net income for the preceding calendar year or 10% of the statutory surplus at the end of the preceding calendar year. For Stonewood Insurance, pursuant to the dividend limitations under North Carolina law, we are not currently allowed to pay dividends without the prior permission of the North Carolina Department of Insurance. In addition, insurance regulators have broad powers to prevent reduction of statutory surplus to inadequate levels and could refuse to permit the payment of dividends calculated under any applicable formula. As a result, we may not be able to receive dividends from our subsidiaries at times and in amounts necessary to pay corporate expenses or meet other obligations. Subject to the foregoing, the maximum amount of dividends available to us from our insurance subsidiaries during 2005 without regulatory approval is $5.8 million.

18




  Litigation and legal proceedings against our insurance subsidiaries could have an adverse effect on our business, results of operations and/or financial condition.

Our insurance subsidiaries have been named as defendants in various legal actions in the course of their insurance operations. Our subsidiaries have responded to the lawsuits, and we believe that there are meritorious defenses and intend to vigorously contest these claims. Adverse judgments in one or more of such lawsuits could require us to pay significant damage amounts or to change aspects of our operations, which could have a material adverse effect on our financial results.

  Severe weather conditions and other catastrophes may result in an increase in the number and amount of claims filed against us.

Our business is exposed to the risk of severe weather conditions and other catastrophes. Catastrophes can be caused by various events, including natural events such as severe winter weather, tornadoes, windstorms, earthquakes, hailstorms, severe thunderstorms and fires, and other events such as explosions, terrorist attacks and riots. The incidence and severity of catastrophes and severe weather conditions are inherently unpredictable. Severe weather conditions and catastrophes can cause losses in a variety of our property/casualty lines and generally result in an increase in the number of claims filed as well as the amount of compensation sought by claimants. It is possible that a catastrophic event or multiple catastrophic events could have a material adverse effect on our results of operations, liquidity and financial condition. It is possible that losses could exceed our catastrophe reinsurance coverage.

Risks Related to This Offering

  Applicable insurance laws and certain provisions in our amended and restated certificate of incorporation make it difficult to effect a change of control.

Under applicable Ohio and North Carolina insurance laws and regulations, no person may acquire control of our company unless that person has filed a statement containing specified information with both the Ohio Department of Insurance and North Carolina Department of Insurance and obtains advance approval for such acquisition. Under applicable laws and regulations, any person acquiring, directly or indirectly (by revocable proxy or otherwise), 10% or more of the voting shares of any other person is presumed to have acquired control of such person, and a person who beneficially acquires 10% or more of our common shares without obtaining advance approval would be in violation of Ohio and North Carolina insurance laws and may be subject to injunctive action enjoining the acquisition and the voting of such shares, and seizure of the shares, as well as other action as determined by the Director of the Ohio Department of Insurance and the Commissioner of the North Carolina Department of Insurance.

In addition, many state insurance laws require prior notification to the state insurance department of a change of control of a non-domiciliary insurance company licensed to transact insurance in that state. While these pre-notification statutes do not authorize the state insurance departments to disapprove the change of control, they authorize regulatory action (including a possible revocation of our authority to do business) in the affected state if particular conditions exist, such as undue market concentration. Any future transactions that would constitute a change of control of us may require prior notification in the states that have pre-acquisition notification laws.

Certain provisions of Delaware law and our certificate of incorporation as it will be amended and restated prior to the effectiveness of this offering make it more difficult to effect the acquisition of control of our company by means of a tender offer, open market purchase, proxy fight or otherwise. The provisions in our certificate of incorporation that will make it difficult to effect a change of control include the authority of our board of directors to issue series of preferred shares with such voting rights and other powers as the board of directors may determine and notice requirements in our by-laws relating to nominations to the board of directors and to the raising of business matters at stockholders' meetings. See "Description of Capital Stock."

  Future sales of our common stock by our existing stockholders in the public market, or the possibility or perception of such future sales, could adversely affect the market price of our common stock.

After giving effect to this offering, our existing stockholders will beneficially own approximately 69.1% of our outstanding common stock (approximately 66.0% if the underwriters' over-allotment option

19




is exercised in full), not including any common stock they or related parties may purchase in this offering. Of these shares, 64.9% are subject to lock-up agreements that prohibit the owners from disposing of our shares for 180 days after the date of this prospectus. See "Shares Eligible for Future Sale." We cannot predict what effect, if any, future sales of shares by these persons, their affiliates or our other stockholders, or the availability of shares for future sale, may have on the prevailing market price of our common stock from time to time. Sales of substantial amounts of our common stock in the public market by these persons, their affiliates or our other stockholders, or the possibility or perception that such sales could occur, could adversely affect prevailing market prices for our common stock. See "Shares Eligible for Future Sale." If such sales reduce the market price of our common stock, our ability to raise additional capital in the equity markets may be adversely affected, and it may be difficult for you to sell your shares at a time and price which you deem appropriate.

  Our directors, executive officers and principal stockholders will own a large percentage of our common stock after this offering, which will allow them to control substantially all matters requiring stockholder approval.

Our directors, executive officers and principal stockholders will beneficially own approximately 37.9% of our outstanding common stock (after giving effect to the conversion of all of our outstanding convertible preferred stock, including shares representing accrued dividends, warrants and options exercisable within 60 days as of July 31, 2005) immediately following completion of this offering. This does not take into account shares of common stock that may be purchased by certain of our directors, executive officers and principal stockholders or related parties in this offering. See "Management—Management and Principal Stockholder Participation in this Offering." Accordingly, these directors, executive officers and principal stockholders will have substantial influence, if they act as a group, over the election of directors and the outcome of other corporate actions requiring stockholder approval or may seek to arrange a sale of our company at a time or under conditions that are not favorable to our other stockholders. These stockholders may also delay or prevent a change of control, even if such a change of control would benefit our other stockholders, if they act as a group. This significant concentration of stock ownership may adversely affect the trading price of our common stock due to investors' perception that conflicts of interest may exist or arise.

  Being a public company will increase our administrative costs and may add other burdens.

As a public company, we will incur significant legal, accounting and other expenses that we did not incur as a private company. In addition, the Sarbanes-Oxley Act of 2002, rules implemented by the Securities and Exchange Commission and new listing requirements of the Nasdaq National Market have required changes in corporate governance practices of public companies. We expect these new rules and regulations to increase our legal and financial compliance costs and to make some activities more time consuming and costly. We also expect these new rules and regulations to make it more difficult and more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced coverage or incur substantially higher costs to obtain coverage. These new rules and regulations could also make it more difficult for us to attract and retain qualified members of our board of directors, particularly to serve on our audit committee.

  You will experience immediate and substantial dilution upon your purchase of our common stock.

Based on an initial offering price of $18.00 per share and after deducting the estimated underwriting discount and estimated offering expenses we must pay in connection with this offering, our adjusted pro forma net tangible book value per share as of March 31, 2005, after giving effect to this offering and the conversion of all of our outstanding convertible preferred stock into common stock, would be $10.87. Accordingly, purchasers of our common stock through this offering will suffer immediate dilution in pro forma net tangible book value per share of $7.13. In the event that we issue additional shares of common stock in the future, including shares that may be issued upon exercise of options and other rights granted under our employee benefit plans, purchasers of our common stock in this offering may experience future dilution. See "Dilution."

20




  We cannot assure you that a public market for our common stock will develop, and our share price may be volatile.

Prior to this offering, there has been no public market for our common stock, and we cannot provide you with any assurance that an active trading market will develop and continue upon the closing of this offering or that the market price for our common stock will not decline below the initial public offering price. The initial public offering price will be determined through negotiations between us and the underwriters. The initial public offering price of our common stock will be based on numerous factors and may not be indicative of the market price for our common stock after the initial public offering. Factors such as variations in our actual or anticipated operating results, changes in or failure to meet earnings estimates of securities analysts, market conditions in the insurance industry, regulatory actions and general economic and securities market conditions, among other factors, could cause the market price of our common stock to decline below the initial public offering price.

SOURCES OF CERTAIN STATISTICAL AND OTHER INFORMATION

USE OF PROCEEDS

We estimate the net proceeds from this offering will be approximately $73.5 million, based on an initial public offering price of $18.00 per share of common stock, and after deducting the underwriting discount and our estimated net offering expenses of $6.5 million. If the underwriters exercise their over-allotment option in full, we estimate our net proceeds will be approximately $84.7 million.

We intend to use the net proceeds from our sale of common shares in this offering to make contributions to the capital of our insurance subsidiaries and for other general corporate purposes, which may include potential acquisitions of companies in the specialty insurance business. We anticipate that we will contribute $60.0 to $65.0 million of the net proceeds to the capital of our insurance subsidiaries in 2005. We do not intend to use these proceeds to discontinue our quota share reinsurance agreement in 2005. See "Management's Discussion and Analysis of Financial Condition and Results of Operations — Outlook" for our future plans with respect to this agreement. We are not currently engaged in discussions regarding any potential acquisition.

DIVIDEND POLICY

We do not anticipate paying any cash dividends on our common stock in the foreseeable future. We cannot assure you that we will declare and pay dividends in the future. Any future determination to pay dividends will be at the discretion of our board of directors and will depend upon our results of operations, financial condition, cash requirements, business prospects, regulatory and contractual restrictions on the payment of dividends by our subsidiaries and other factors our board of directors deems relevant. We currently intend to retain any future earnings to fund the development and growth of our business. For a discussion of our cash resources and needs, see "Management's Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources."

Our status as a holding company and a legal entity separate and distinct from our subsidiaries affects our ability to pay dividends and make other payments. As a holding company without significant operations of our own, the principal sources of our funds are dividends and other payments from our subsidiaries. The ability of our insurance subsidiaries to pay dividends to us is subject to limits under insurance laws of the states in which our insurance subsidiaries are domiciled. Furthermore, dividends from our subsidiaries are limited to minimum capital requirements in state regulations. See "Management's Discussion and Analysis of Financial Condition and Results of Operations – Liquidity and Capital Resources" and "Regulation."

DILUTION

Our net tangible book value — historical and net tangible book value per share — historical as of March 31, 2005 was approximately $78.9 million, prior to the effect of the 10 for 1 split of our common stock which we intend to effect prior to the completion of this offering. Our pro forma net tangible book value as of March 31, 2005 was approximately $78.9 million, or $8.09 per share of common stock, based on 9,760,450 shares of common stock outstanding after giving effect to the conversion of all outstanding shares of our convertible preferred stock into common stock, including shares representing accrued dividends, immediately prior to the effectiveness of this offering and the 10 for 1 split of our common stock which we intend to effect prior to the completion of this offering. Pro forma net tangible book value per share is determined by dividing our net tangible book value (total tangible assets less total liabilities) by the pro forma number of shares of common stock outstanding before giving effect to this offering.

After giving effect to the sale of 4,444,000 shares of common stock offered by us at an initial public offering price of $18.00 per share and after deducting the estimated underwriting discount and offering expenses, our pro forma adjusted net tangible book value as of March 31, 2005 would have been $154.4 million, or $10.87 per share. This represents an immediate increase in the net tangible book value of $2.78 per share to existing stockholders, and an immediate dilution of $7.13 per share to new investors. The following table illustrates the per share dilution:


Net tangible book value per share as of March 31, 2005 — historical       $ 78,917,634.00  
Pro forma net tangible book value per share as of March 31, 2005         8.09

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and the related notes included elsewhere in this prospectus. The discussion and analysis below includes certain forward-looking statements that are subject to risks, uncertainties and other factors described in "Risk Factors" beginning on page 11 and elsewhere in this prospectus that could cause actual results to differ materially from those expressed in, or implied by, those forward-looking statements. See "Forward-Looking Statements".

Overview

James River Group, Inc. is a holding company that owns and manages property/casualty insurance companies focused on specialty insurance niches. We were organized in September 2002. We seek to earn a profit from underwriting. This means that we intend for the premiums we earn in any period to be sufficient to pay all of the losses and loss adjustment expenses we incur during the period as well as all of the expenses associated with our operations. Our insurance companies individually underwrite each risk that we issue a policy for, and our companies do not grant any underwriting authority to our insurance agents and brokers.

Our consolidated results include the results for our holding company and five wholly-owned subsidiaries:

James River Insurance Company (formerly Fidelity Excess and Surplus Insurance Company) underwrites property/casualty insurance on an excess and surplus lines basis in 48 states and the District of Columbia. James River Insurance sells its policies through a network of independent wholesale and retail brokers throughout the United States.

James River Management Company, Inc. employs professionals with experience operating a property/casualty insurance company writing business on an excess and surplus basis to manage James River Insurance.

Stonewood Insurance Company underwrites workers' compensation insurance for the construction industry in North Carolina. Stonewood Insurance was licensed to write insurance in North Carolina in November 2003, and its first insurance policies were written effective January 1, 2004. Stonewood Insurance sells its policies through a retail network of independent insurance agencies.

Stonewood Insurance Management Company, Inc. employs professionals with experience operating a workers' compensation insurance company to manage Stonewood Insurance.

Potomac Risk Services, Inc. was formed in 2004 to provide surplus lines brokerage services. Potomac had no operating activities in 2004 or in the first quarter of 2005.

The table shows an increase in our net income and stockholders' equity and a reduction in our combined ratio for each quarter over the period shown. Our combined ratios declined over the period shown principally because of reductions in our expense ratios. The expense ratios declined primarily due to the fact that the infrastructure that we built to process our insurance business in 2003 and early 2004 allowed us to increase production throughout 2004 and the first quarter of 2005 without experiencing a proportional increase in expenses.

Our loss ratio improved for the three months ended March 31, 2005 primarily due to $2.3 million of favorable loss and loss adjustment expense reserve development that we experienced for the quarter. The majority of this favorable reserve development, approximately $1.7 million, was reported on James River Insurance's property lines related to the 2004 accident year. This favorable development on the property lines resulted from reductions in our estimates of incurred but not reported losses and loss adjustment expenses. Excluding the effects of the $2.3 million of favorable reserve development from our results, our loss ratio for the three months ended March 31, 2005 was 63.3%.

We entered into a quota share reinsurance contract effective January 1, 2005 that transfers a portion of the risk related to certain property/casualty business written by James River Insurance in 2005 to reinsurers in exchange for a portion of our direct written premiums on that business. Under terms of the agreement, James River Insurance cedes a portion of its other liability occurrence and primary property business, which includes business written by the General Casualty, Manufacturers and Contractors and Primary Property divisions. By transferring risk to the reinsurers, we also reduced the amount of capital required to support the insurance operations of James River Insurance.

James River Insurance receives a ceding commission equal to 25% of ceded earned premium and pays a reinsurer margin equal to 4.5% of ceded earned premium. The ceding commission cannot be reduced, although under certain circumstances, based on underwriting results, James River Insurance is entitled to an additional profit contingent commission up to an amount equal to all of the reinsurer's profits above the margin. James River Insurance maintains a funds-held account which is credited interest at a fixed rate of 3.75% annually. The funds-held account balance is recorded as a liability on our balance sheet, and at March 31, 2005 the balance of the account was $5.2 million. Assets supporting the funds-held liability are not segregated or restricted. The contract has a loss ratio cap of 115%, which means that we cannot cede any losses in excess of a 115% loss ratio to the reinsurer. For the three months ended March 31, 2005, ceded earned premiums related to this quota share treaty were $7.6 million, ceded loss and loss adjustment expenses were $5.3 million and our reinsurance ceding commission was $1.9 million.

During 2004, our agency network grew significantly. James River Insurance added two new underwriting divisions, and Stonewood Insurance initiated its insurance operations. The addition of renewal premiums at James River Insurance starting July 1, 2004 as the first policies issued July 1, 2003 came up for renewal contributed to the growth in direct written premiums, net written premiums and net earned premiums in the quarters ended September 30, 2004 and December 31, 2004.

We issued 13,500 shares of Series B convertible preferred stock during the second quarter of 2004, with proceeds of $1.3 million.

We issued 200,000 shares of Series B convertible preferred stock during the fourth quarter of 2003, with proceeds, net of notes receivable from employees and directors, of $19.7 million. This transaction was the primary reason for the increase in stockholders' equity from September 30, 2003 to December 31, 2003.

Critical Accounting Policies

We have identified the accounting policies below as critical to the understanding of our results of operations and financial position. We use significant judgments and estimates concerning future results and developments in applying these accounting policies and in preparing our financial statements. Actual results may differ from these estimates. We evaluate our estimates on a continual basis using information that we believe to be relevant. For a detailed discussion of our significant accounting policies, see Note 1 to the 2004 audited consolidated financial statements included in this prospectus.

Reserve for Losses and Loss Adjustment Expenses

The reserve for losses and loss adjustment expenses represents our estimated ultimate cost of all reported and unreported losses and loss adjustment expenses incurred and unpaid at the balance sheet date. We do not discount the reserve for losses and loss adjustment expenses. We estimate the reserve for losses and loss adjustment expenses using individual case-basis valuations of reported claims. We also use statistical analyses to estimate the cost of losses that have been incurred but not reported to us. Those estimates are based on historical information and on estimates of future trends that may affect the frequency of claims and changes in the average cost of claims that may arise in the future. As a relatively new company, our historical loss experience is limited.

We utilize two primary actuarial methods to arrive at our loss reserve estimates for each line of business. One of the primary methods, the incurred Bornhuetter-Ferguson method, utilizes our initial expected loss ratio (the ratio of losses and loss adjustment expenses incurred to net earned premiums), expected reporting patterns for losses based on industry data and our actual reported losses and loss adjustment expenses to estimate the reserve. The other primary method, the loss ratio method, estimates the reserve by applying an expected loss ratio to net earned premiums by line of business. For both methods, the expected loss ratio is established using judgment, and is based primarily on industry data and the experience of our management team in writing similar insurance coverages. The expected loss ratio used in the loss ratio method is judgmentally adjusted up or down when the level of reported losses for a specific accident year for a line of business leads us to conclude that the ultimate loss ratio will differ from our initial expected loss ratio. The expected loss ratio used in the incurred Bornhuetter-Ferguson method is typically not adjusted after it is initially set, because the mechanics of that method already incorporate departures from expected reported losses into the reserve calculations. We did not change our actuarial methods during the three months ended March 31, 2005. We have generally selected the method that yields the highest reserve for each line of business. At March 31, 2005, our aggregate reserve is the sum of the selected estimates for each line of business. This aggregate reserve reflects our best estimate. Since we have selected the higher of the two methods at each financial statement date, the aggregate reserve includes components calculated using the incurred Bornhuetter-Ferguson method and components calculated using the loss ratio method. This combination of methods varies by line of business and period. The primary factor contributing to the difference between the methods is that the incurred Bornhuetter-Ferguson method incorporates assumptions regarding industry reporting patterns for losses and our reported loss and loss adjustment expenses which are not reflected in the loss ratio method. This means that the incurred Bornhuetter-Ferguson method is more sensitive to our level of reported losses than the loss ratio method.

The estimated net reserve at March 31, 2005 using the incurred Bornhuetter-Ferguson method was $48.2 million, and the estimated net reserve at March 31, 2005 using the loss ratio method was $55.6 million. Each of these reserve estimates are individual point estimates and do not constitute an actuarial range. Given that our insurance companies have limited historical experience and that our two primary actuarial methods utilize industry data, that losses on our casualty business often take a number of years

31




to develop and that we write difficult classes of business which typically do not meet the risk criteria of standard carriers, we believe that we do not have sufficient evidence at this time to conclude that our ultimate loss ratios will be significantly better than our expected loss ratios. In most instances we have recorded the reserve estimate derived using the loss ratio method as our best reserve estimate because the expected loss ratio used in this method is derived from our management's experience in the lines of business that we write and our current underwriting criteria. We record the reserve estimate derived from the incurred Bornhuetter-Ferguson method as our best estimate when the level of actual reported losses provides sufficient evidence that the ultimate loss ratio will exceed our expected loss ratio. When the level of actual reported losses provides sufficient evidence that the ultimate loss ratio will be less than our expected loss ratio, we generally reduce the expected loss ratio used in the loss ratio method. We believe that generally selecting the higher of our two primary methods by line of business as the basis for our best reserve estimates at this early stage in our history is appropriate because more evidence is needed before we can reasonably conclude that our loss ratios will be significantly better than our expectations. In the future as more information becomes available to us and we develop more experience in our casualty business, we may adjust or change our actuarial methods. Such future methods may not necessarily result in selecting the highest estimate of our actuarial methods.

Reserve estimates derived using the incurred Bornhuetter-Ferguson method are driven by our assumptions related to the expected loss ratio and the expected reporting pattern for losses, while reserve estimates derived using the loss ratio method are driven by our assumptions related to the expected loss ratio and are not sensitive to reporting patterns. Reporting pattern means the estimated percentage of the ultimate losses for a particular line of business that have been reported at the valuation date. The table below quantifies the impact that reasonably likely changes in these two variables, the expected loss ratio and the expected reporting pattern for losses, would have on the recorded reserve for losses and loss adjustment expenses at March 31, 2005. The reporting pattern scenarios below only apply to the incurred Bornhuetter-Ferguson analysis. In the table below, the expected loss ratio and the expected reporting pattern refer to assumptions related to those two variables that we made in calculating the net reserves that we recorded at March 31, 2005.

The sensitivity analysis above was based on the weighted-average assumptions presented in the table below. For the expected loss ratio assumptions, the expected loss ratio represents a weighted average of the expected loss ratios used for each of our lines of business, with the expected loss ratio for each line weighted based on net earned premiums. For the expected reporting pattern assumptions, the expected reporting pattern represents a weighted average of the percentage of ultimate losses assumed to be reported to us at March 31, 2005 for each of our lines of business weighted based on net earned premiums.

We believe that loss ratios 5% above or below our expected loss ratio constitute a reasonable range of expectations for each major line of business. In addition, we believe that the adjustments that we made to speed up or slow down the reporting patterns in the sensitivity analysis above are reasonably likely outcomes. Under the incurred Bornhuetter-Ferguson method, slowing the reporting pattern results in an increase in the estimate of reserves, because reported losses are seen as a smaller percentage of the ultimate reported losses, resulting in an increase in estimated unreported losses. Similarly, using a faster reporting pattern results in a decrease in the estimate of reserves. In determining the amounts by which to slow or accelerate the reporting patterns for the sensitivity analysis presented above, we applied judgment to reflect the fact that the variability of reasonably likely reporting pattern outcomes varies by major line of business. There is very little variability around our expected reporting patterns for our excess and surplus insurance property lines, because property claims are typically reported relatively quickly. Conversely, there is considerably more variability around our expected reporting patterns for our excess and surplus insurance casualty lines, because losses on casualty business often take a number of years to develop. Reporting patterns for workers' compensation insurance are generally slower than reporting patterns for our excess and surplus insurance property lines and generally faster than reporting patterns for our excess and surplus insurance casualty lines. Accordingly, the variability around our expected reporting patterns for workers' compensation insurance is greater than it is for our excess and surplus insurance property lines and less than it is for our excess and surplus insurance casualty lines. The impact of recording the net reserve for losses at the highest value from the sensitivity analysis above would be to reduce net income by $3.6 million and to reduce stockholders' equity at March 31, 2005 by 4.4%. The impact of recording the net reserve for losses at the lowest value from the sensitivity analysis above would be to increase net income by $3.6 million and increase stockholders' equity at March 31, 2005 by 4.3%. Such changes in the net reserve for losses and loss adjustment expenses would not have an immediate impact on our liquidity, but would affect cash flow in future periods as the incremental or reduced amount of losses are paid.

Our reserves are driven by a number of important assumptions including litigation and regulatory trends, legislative activity, social and economic patterns and claims inflation assumptions. Our reserve estimates reflect current inflation in legal claims settlements and assume we will not be subject to losses from significant new legal liability theories. Our reserve estimates also assume that we will not experience significant losses from mass torts and that we will not incur losses from future mass torts not known to us today. While it is not possible to predict the impact of changes in this environment, if new mass torts or expanded legal theories of liability emerge, our incurred but not reported, commonly referred to as IBNR, claims may differ substantially from our IBNR reserves. Our reserve estimates assume that there will not be significant changes in the regulatory and legislative environment. The impact of potential changes in the regulatory or legislative environment is difficult to quantify in the absence of specific, significant new regulation or legislation. In the event of significant new regulation or legislation, we will attempt to quantify its impact on our business.

Our reserve estimates assume that the inflation assumption implicitly built into our expected loss ratio will continue into the future. Unexpected changes in loss cost inflation can occur through changes in general inflationary trends, changes in medical technology and procedures and changes in legal theories of liability. The estimated impact of an additional one percent increase in loss cost inflation as of March

33




31, 2005 is to increase loss and loss adjustment expense reserves by approximately $500,000, decrease net income by $325,000 and reduce stockholders' equity by 0.4%. Such an increase in reserves would not have an immediate impact on our liquidity, but would reduce cash flow over time as those incremental losses are paid. IBNR reserve estimates are inherently less precise than case reserve estimates. A 5% change in net IBNR reserves at March 31, 2005 would equate to a $2.5 million change in the reserve for losses and loss adjustment expenses, which we sometimes refer to as LAE, a $1.6 million change in net income and a 1.9% change in stockholders' equity at March 31, 2005. Although we believe that our reserve estimates are reasonable, it is possible that our actual loss experience may not conform to our assumptions. Specifically, our actual ultimate loss ratio could differ from our initial expected loss ratio or our actual reporting patterns for losses could differ from the expected reporting patterns based on industry data. Accordingly, the ultimate settlement of losses and the related loss adjustment expenses may vary significantly from the estimates included in our financial statements. We continually review our estimates and adjust them as necessary as experience develops or new information becomes known to us. Such adjustments are included in current operations.

Losses and loss adjustment expenses for 2004 reflect $156,000 of favorable development on the reserve for losses and loss adjustment expenses at December 31, 2003. Losses and loss adjustment expenses for the three months ended March 31, 2005 reflect $2.3 million of favorable development on the reserve for losses and loss adjustment expenses at December 31, 2004. The majority of this favorable development, approximately $1.7 million, was reported for James River Insurance's property lines and related to the 2004 accident year. Losses and loss adjustment expenses for the three months ended March 31, 2004 reflect $93,000 of favorable development on the reserve for losses and loss adjustment expenses at December 31, 2003.

Investments

We evaluate our investments regularly to determine whether there are declines in value that are other-than-temporary. When we determine that a security has experienced an other-than-temporary impairment, the impairment is recognized as a realized investment loss. We consider a number of factors in assessing whether an impairment is other-than-temporary, including the amount and percentage that fair value is below amortized cost, the length of time that fair value has been below amortized cost and the credit quality ratings for the securities, with a special emphasis on securities downgraded below investment grade.

We carry securities classified as "available-for-sale" at fair value and unrealized gains and losses on such securities, net of deferred taxes, are reported as a separate component of accumulated other comprehensive income. We do not have any securities classified as "held-to-maturity" or "trading."

We report short-term investments at cost. Short-term investments include investments both readily convertible to known amounts of cash and having maturities of 12 months or less upon our acquisition of the investment.

Income Taxes

We review the need for a valuation allowance related to our deferred tax assets each quarter. We reduce our deferred tax assets by a valuation allowance when we determine that it is more likely than not that some portion or all of the deferred tax assets will not be realized. The assessment of whether or not a valuation allowance is needed requires us to use significant judgment. Our assessment includes consideration of the amount of taxable income generated since we were formed in 2002, trends in earnings and future expectations. Income tax expense for 2004 reflects a reduction in the deferred tax valuation allowance of $1.9 million.

The effective tax rate for the three months ended March 31, 2005 is 33.5%. Income tax expense for the three months ended March 31, 2005 differs from the amount computed by applying the Federal statutory income tax rate to income before income taxes primarily due to interest on tax-advantaged state and municipal securities. There was no income tax expense for the three months ended March 31, 2004 because taxable income for the quarter was fully offset by net operating loss carryforwards.

34




Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to our taxable income in the years in which temporary differences between the financial statement carrying amounts of assets and liabilities and their respective tax bases are expected to be recovered or settled.

Reinsurance

Some of the reinsurance treaties of James River Insurance contain retrospective experience rated provisions in which the cost of reinsurance purchased by James River Insurance or the amount of ceding commission James River Insurance receives from its reinsurers varies based on the level of incurred losses ceded to the reinsurers, subject to a maximum and a minimum specified in the reinsurance contract. We estimate the ultimate loss experience in determining the amounts to record in the financial statements for premiums ceded to reinsurers and ceding commissions earned by James River Insurance. As loss experience develops, we adjust the ceded premium rates and ceding commission rates to reflect the loss experience. Although we believe that our estimates are reasonable, it is possible that our actual loss experience may not conform to our assumptions. We continually review our estimates and adjust them as necessary as experience develops or new information becomes known; such adjustments are included in current operations. The impact of these adjustments in 2004 was to increase net earned premiums for 2004 by $484,000 for the true-up of premiums earned in 2003 and to increase losses and loss adjustment expenses by approximately $290,000. There were no adjustments to our assumptions related to retrospective experience rated reinsurance provisions for the three month periods ended March 31, 2005 and 2004.

Reinsurance premiums, commissions, losses and loss adjustment expenses on reinsured business are accounted for on a basis consistent with that used in accounting for the original policies issued and the terms of the reinsurance contracts. Reinsurance recoverables and prepaid reinsurance premiums are reported as assets. Other amounts payable to reinsurers or receivable from reinsurers are netted where the right of offset exists.

We receive ceding commissions in connection with certain ceded reinsurance. The ceding commissions are recorded as a reduction of other operating expenses.

Intangible Insurance Assets

We possess intangible insurance assets with an indefinite life. Financial Accounting Standards Board (FASB) Statement No. 142, Goodwill and Other Intangible Assets, prescribes that an intangible asset with an indefinite useful life should not be amortized but instead should be tested for impairment on at least an annual basis, based on a comparison of its fair value and its carrying value. In performing the impairment evaluation for these intangible assets, we first determine that the intangible assets purchased continue to have an indefinite life. Next, we determine the fair value of the intangible assets and compare this fair value to the carrying value. If the carrying value exceeds the fair value, we recognize an impairment writedown to fair value on the intangible asset, and the impairment is reported through earnings. We have had no such impairment writedowns for the years ended December 31, 2004 and December 31, 2003 or for the three month periods ended March 31, 2005 and 2004.

See Note 1 to our audited consolidated financial statements included elsewhere in this prospectus for a discussion of our other significant accounting policies.

Acquisition Summary

On June 30, 2003, we acquired Fidelity Excess and Surplus Insurance Company (Fidelity), which we renamed James River Insurance Company, from American Empire Surplus Lines Insurance Company (American Empire), a member of the American Financial Group. The purchase price totaled $28.9 million, including $84,000 of acquisition expenses.

Our goal in making this acquisition was to acquire a company having regulatory approvals to write business on an excess and surplus lines basis in as many states as possible. With the purchase of Fidelity, we acquired surplus lines approval in 40 states and the District of Columbia and insurance licenses in four states. We recorded intangible insurance assets of $4.2 million in connection with the purchase. The

35




intangible insurance assets arise from regulatory approvals granted by the various state insurance departments to write insurance business on an excess and surplus lines basis in their states. Once these regulatory approvals are granted, we can routinely renew them at little cost provided that we have complied with rules and regulations. We expect cash flows related to the regulatory approvals to transact insurance business to continue indefinitely, so we have concluded that these intangible assets have indefinite lives.

At the time of our acquisition of Fidelity, Fidelity had a reinsurance agreement with its parent, American Empire. Under this reinsurance agreement, Fidelity ceded all of its liabilities on all insurance business it wrote or assumed through June 30, 2003 to American Empire. American Empire and Fidelity also entered into a trust agreement under which American Empire established a trust account with Fidelity as the beneficiary. Under the trust agreement, American Empire must maintain assets with a current fair value greater than or equal to the ultimate net aggregate losses recoverable under the reinsurance agreement. At March 31, 2005 and December 31, 2004, we had $2.8 million and $2.6 million, respectively, of reinsurance recoverables from American Empire related to the reinsurance agreement. Cessions under the reinsurance agreement are net of third party reinsurance. As of March 31, 2005 and December 31, 2004, there were $2.3 million and $1.9 million, respectively, of recoverables from third party reinsurers associated with the business that Fidelity wrote before we acquired it. In the event that these third party reinsurers default on their obligations, the recoverables would become subject to our reinsurance agreement with American Empire and, accordingly, American Empire will indemnify us for any such uncollectible third party reinsurance recoverables. At March 31, 2005 and December 31, 2004, trust assets had a fair value of $7.6 million and $7.7 million, respectively, which exceeded the ultimate net aggregate losses recoverable under the reinsurance agreement as required by the trust agreement. The trust assets are limited to cash and investments permitted by Ohio insurance laws. None of the trust assets can be in capital stock or in fixed income securities that are below investment grade. As additional security, Great American Insurance Company, an affiliate of American Empire, has irrevocably and unconditionally guaranteed the performance by American Empire of all of its obligations under the reinsurance agreement and trust agreement. Great American Insurance Company and American Empire have financial strength ratings of "A" (Excellent) from A.M. Best. We remain liable for the liabilities ceded under the reinsurance agreement in the event that the trust assets are insufficient to cover the ultimate net aggregate losses recoverable under the reinsurance agreement and American Empire and Great American Insurance Company default on their respective obligations.
