("Trenwick") is a specialty insurance underwriting organization with multiple distribution platforms in insurance and reinsurance operating through its subsidiaries located in the United States and the United Kingdom. Trenwick's four principal operating units are Trenwick America Reinsurance Corporation ("Trenwick America Re"), which provides treaty reinsurance to insurers of property and casualty risks in the United States; Trenwick International Limited ("Trenwick International"), which underwrites treaty and facultative reinsurance as well as specialty insurance on a worldwide basis; Chartwell Managing Agents Limited ("Chartwell Managing Agents"), Trenwick's managing agency at Lloyd's; and Canterbury Financial Group Inc. ("Canterbury Financial"), which underwrites U.S. property and casualty insurance through specialty program administrators. Trenwick was incorporated in the State of Delaware in 1985. Trenwick America Re, a Connecticut corporation, operated as a subsidiary of Trenwick America Corporation from 1983 through 1985 and was acquired by Trenwick in 1985 as a result of a corporate restructuring. Trenwick acquired Trenwick International in February 1998 and Chartwell Re Corporation ("Chartwell") in October 1999. In connection with the acquisition of Chartwell, Trenwick acquired Chartwell Managing Agents, Chartwell Reinsurance Company ("Chartwell Reinsurance"), whose reinsurance business was assumed by Trenwick America Re, and The Insurance Corporation of New York ("INSCORP") and Dakota Specialty Insurance Company ("Dakota"), both of which are operating companies for Canterbury Financial. In addition, Trenwick owns several inactive Bermuda subsidiaries. On December 19, 1999, Trenwick announced that it had entered into a definitive agreement to combine with LaSalle Re Holdings Limited, with shareholders of each company to receive shares in a new Bermuda holding company to be named Trenwick Group Ltd. This transaction is expected to be completed in the second quarter of 2000. Each of Trenwick's operating insurance company subsidiaries is rated "A" (Excellent) by A.M. Best Company and has been assigned an A+ financial strength rating by Standard & Poor's. All of Chartwell Managing Agents' syndicates enjoy the benefit of the ratings of Lloyd's, which is rated "A" (Excellent) by A.M. Best Company and has an A+ claims paying ability rating from Standard & Poor's. These ratings are based upon factors that may be of concern to policy or contract holders, agents and intermediaries, but may not reflect the considerations applicable to an equity investment in a reinsurance or insurance company. A change in any such rating is at the discretion of the respective rating agencies. Trenwick's gross and net premium writings for its operational units are as follows: 1999 1998 1997 -------- -------- -------- Gross Premiums Written Trenwick America Re $210,921(1) $218,249 $248,662 Trenwick International 171,698 105,114(2) -- Chartwell Managing Agents 84,834(3) -- -- Canterbury Financial 38,088(4) -- -- -------- -------- -------- Total $505,541 $323,363 $248,662 ======== ======== ======== Net Premiums Written Trenwick America Re $155,108(1) $169,112 $195,230 Trenwick International 129,399 81,107(2) -- Chartwell Managing Agents 64,462(3) -- -- Canterbury Financial 5,641(4) -- -- -------- -------- -------- Total $354,610 $250,219 $195,230 ======== ======== ======== (1) Includes reinsurance business of Chartwell Reinsurance and its subsidiaries since its acquisition on October 27, 1999.

Trenwick America Reinsurance Corporation Trenwick America Re, which comprised 44% of Trenwick's total net premiums written in 1999, underwrites United States treaty reinsurance, which accounts for the majority of its business, as well as a small amount of facultative reinsurance. In this section, Trenwick America Re's 1999 results include the reinsurance business of Chartwell Reinsurance and its subsidiaries since its acquisition on October 27, 1999. Trenwick America Re generally obtains all of its business through brokers and reinsurance intermediaries which seek its participation on reinsurance being placed for their customers. In underwriting reinsurance, Trenwick America Re does not target types of clients, classes of business or types of reinsurance. Rather, it selects transactions based upon the quality of the reinsured, the attractiveness of the reinsured's insurance rates and policy conditions and the adequacy of the proposed reinsurance terms. Trenwick America Re's commitment is currently limited to $2,500,000 per contract on casualty treaty business and $1,500,000 on property business. Larger commitments are subject to Trenwick's Underwriting Committee referral process. 2 Trenwick America Re's net premiums written by line of business are set forth in the following table for the periods indicated. Trenwick America Reinsurance Corporation Net Premiums Written By Lines of Business (in thousands) 1999(1) 1998 1997 --------- --------- --------- Casualty Automobile Liability $ 17,831 $ 51,299 $ 50,187 Errors and Omissions 45,557 36,655 40,063 General Liability 22,170 17,743 20,795 Accident and Health 17,922 11,014 6,326 Medical Malpractice 3,422 7,700 10,293 Workers' Compensation 8,297 3,025 18,328 Products Liability 1,834 2,312 1,743 Other Casualty 12,431 2,697 9,133 --------- --------- --------- Total Casualty 129,464 132,445 156,868 --------- --------- --------- Property 25,644 36,667 38,362 --------- --------- --------- Total $ 155,108 $ 169,112 $ 195,230 ========= ========= ========= (1) Includes reinsurance business of Chartwell Reinsurance and its subsidiaries since its acquisition on October 27, 1999. The major lines of reinsurance currently written by Trenwick America Re are automobile liability, errors and omissions, general liability and accident and health. Together these lines account for an aggregate of at least 67% of its net premiums written in all years indicated. The overall decline in net premiums written since 1997 is a result of three principal causes. Competition among primary companies has caused cedants to reduce their own premium writings or restructure their reinsurance programs, reducing the amount of reinsurance they purchase. As a result of consolidation within the industry, many ceding companies are now larger and financially stronger, enabling them to retain more risk. In addition, increasingly intense competition in the reinsurance markets has driven reinsurance prices on a number of accounts below pricing levels which Trenwick America Re will accept. The 65% decline in automobile liability net premium writings in 1999 resulted from the non-renewal of two significant accounts, one of which was commuted in the fourth quarter of 1999. Accident and health net premiums written increased by 63% compared to 1998 as a result of Trenwick America Re's strategic alliance with Duncanson and Holt. This account was non-renewed in 2000 following the sale of Duncanson and Holt. In 1999, the amount of property business, including automobile physical damage, underwritten by Trenwick America Re remained constant as a percentage of total net written premiums. Three ceding companies accounted for approximately 25%, 38%, and 32% of Trenwick America Re's gross premiums written in 1999, 1998 and 1997, respectively. During 1999, Duncanson and Holt, American International Group and CNA Insurance Companies accounted for 11%, 7% and 7%, respectively, of Trenwick America Re's gross premiums written. While Trenwick America Re believes that the loss of these accounts will not have a material adverse effect on the business and operations of Trenwick, Trenwick does not believe that such a loss would have a long-term adverse effect because of Trenwick's 3 competitive position within the reinsurance market and the availability of business from other brokers and ceding companies. Further, Trenwick believes that it will continue to underwrite new business to replace the accounts. Trenwick International Limited Trenwick International's business, which accounted for 36% of Trenwick's total net premiums written in 1999, consists principally of insurance and facultative reinsurance of specialty classes. Trenwick International also underwrites property and casualty treaty reinsurance. In the latter part of 1998, Trenwick International opened a branch office in Paris which specializes in facultative reinsurance of large, technically complex property risks. Premiums written by the Paris branch in 1999 were not material. Trenwick International also obtains all of its business through brokers. Trenwick International's business consists of Specialist Risk Underwriting ("SRU") which includes direct insurance, facultative reinsurance and treaty reinsurance. The following table reflects Trenwick International's net premiums written by type of business for 1999 and 1998. International Net Premiums Written By Type of Business (dollars in thousands) 1999 1998 ----------------- ----------------- SRU 98,926 76% 83,397 83% Treaty 30,473 24% 17,385 17% ----------------- ----------------- Total $129,399 100% 100,782 100% ================= ================= Specialist Risk Underwriting SRU underwrites business in both London and Paris. Trenwick's branch office in Paris was opened in September of 1998. The principal lines of business underwritten in 1999 and 1998 include property, engineering, accident and health professional indemnity, financial institutions, liability, extended warranty and yacht hull. In 1999, approximately 53% of Trenwick International's net premiums were written directly as insurance. Trenwick's Paris branch specializes in large, complex property risks that require a high degree of underwriting expertise. Trenwick International generally underwrites this business, which includes large manufacturing facilities, construction projects as well as both onshore and offshore energy risks, as facultative reinsurance, but can also function directly as an insurer. The Paris branch benefits from a pool of underwriters trained as engineers and has emerged as a center for this type of technical underwriting. Treaty Trenwick International's treaty business includes liability business, which accounted for approximately 51% of treaty business in 1999, as well as property and credit business. Treaty is written both on a proportional and non-proportional basis. 4 Chartwell Managing Agents Trenwick participates in the Lloyd's market through Chartwell Managing Agents, which is a managing agent at Lloyd's and through four Lloyd's corporate members. Chartwell Managing Agents receives fees and profit commissions in respect of the underwriting and administrative services it provides to the Lloyd's underwriting syndicates that it manages. For the 2000 year of account, Chartwell Managing Agents manages three syndicates with a total underwriting capacity of approximately $377.1 million. In 1998 and 1999, Chartwell Managing Agents sold to third parties the rights to manage syndicates 866 (motor), 947 (non-marine) and 994 (non-marine) and combined into a single syndicate for the 2000 year of account the remaining non-life syndicates. Trenwick retains the benefits and obligations with respect to its Lloyd's corporate member participation interests in those syndicates for the open years of account at the time of the sale. Trenwick's Lloyd's corporate members participated on three Lloyd's syndicates for the 2000 year of account, providing an aggregate of approximately $350.1 million of capacity to those syndicates. Approximately 93% of Chartwell Managing Agents syndicates' 2000 year of account capacity was supplied by Trenwick. Classes of business covered by Chartwell Managing Agents' syndicates include marine, non-marine property, non-marine liability, motor, aviation and life. The table set forth below shows the gross premiums written for Trenwick's Lloyd's corporate members for the periods indicated. All amounts in the table below are presented in accordance with U.S. generally accepted accounting principles ("GAAP").

Data shown for 1998 and that portion of 1999 prior to October 27, 1999 is not included in Trenwick's financial statements because Trenwick acquired Chartwell Managing Agents and its related Lloyd's corporate members on October 27, 1999. Canterbury Financial Group Canterbury Financial Group develops insurance programs through specialty production sources with a focus on a specific line or lines of business, with a limited geographic emphasis, and where the program administrator's compensation is adjusted based on the underwriting results of the business. Canterbury Financial Group evaluates each business relationship based upon the underwriting experience and operational expertise of the production source. Canterbury Financial Group periodically performs underwriting, claims and operational audits of each of its production sources. Canterbury Financial Group's gross written premiums grew 32.7%, 4.3% and 81.3% for the years ended December 31, 1999, 1998 and 1997, respectively, over the prior year. The increases in premium reflect the 5 geographic expansion of existing programs as well as the development of new programs during the periods shown. The table set forth below shows the gross premiums written for Canterbury Financial Group for the periods indicated: Canterbury Financial Group Gross Premiums Written by Line of Business (dollars in thousands)(1) Year Ended December 31, ---------------------------------------------------------------------------------- 1999 1998 1997 --------------------- --------------------- ---------------------- Amount Total Amount Total Amount Total -------- ----- -------- ----- -------- ------ Commercial Multiple Peril $ 41,909 28.4% $ 45,737 41.2% $ 48,404 45.4% General Liability 36,743 25.0 31,575 28.4 30,418 28.6 Automobile 46,471 31.5 23,354 21.0 22,267 20.9 Workers Compensation 12,589 8.5 4,224 3.8 4,169 3.9 Homeowners and Other 9,786 6.6 6,241 5.6 1,285 1.2 -------- ----- -------- ----- -------- ----- Total $147,498 100.0% $111,131 100.0% $106,543 100.0% ======== ===== ======== ===== ======== ===== (1) Data shown for 1998 and that portion of 1999 prior to October 27, 1999 is not included in Trenwick's financial statements because Trenwick acquired Canterbury Financial on October 27, 1999. During the year ended December 31, 1999, Canterbury Financial Group underwrote approximately 64% of its gross premiums through three managing general agents, of which Florida Intracoastal Underwriters accounted for approximately 31%, HDR Insurance Services accounted for approximately 22% and Inter-Reco accounted for approximately 11%. No other managing general agent accounted for more than 10% of Canterbury Financial Group's gross insurance premiums written for such period. In order to reduce the potential adverse effect arising from the termination of any specific business relationship, Canterbury Financial Group continues to seek to establish and develop relationships with a large number of managing general agents. While management believes that its relationships with its managing general agents are satisfactory, the termination of all or a substantial number of these relationships could have a material adverse effect on the business and operations of Canterbury Financial Group. Marketing Trenwick generally obtains its business through insurance and reinsurance brokers which represent the ceding company and clients in negotiations for the purchase of insurance or reinsurance. The process of effecting a brokered placement typically begins when a client or ceding company enlists the aid of a broker in structuring an insurance or reinsurance program. Often the various parties will consult with one or more lead underwriters as to the pricing and contract terms of the protection being sought. Once the terms quoted by the lead underwriter have been approved, the broker will offer participation to qualified insurers or reinsurers until the program is fully subscribed at terms agreed to by all parties. Trenwick pays such intermediaries or brokers commissions representing negotiated percentages of the premium it writes. These commissions constitute part of Trenwick's total acquisition costs and are included 6 in its underwriting expenses. Brokers do not have the authority to bind Trenwick America Re with respect to agreements. Under certain limited circumstances, selected administrators have the authority to bind Trenwick International, Chartwell Managing Agents and Canterbury Financial Group business. These administrators are subject to periodic financial and operational reviews. Trenwick does not commit in advance to accept any portion of the business that brokers submit to it. Business from any company, whether new or renewal, is subject to acceptance by Trenwick. During 1999, three reinsurance brokers, AON Reinsurance Agency, Guy Carpenter and E. W. Blanch generated 37%, 16% and 8%, respectively, of Trenwick America Re's gross written premiums. These brokers are among the ten largest brokers in the insurance and reinsurance industry. Loss of all or a substantial portion of the business provided by Trenwick's brokers could have a material adverse effect on the business and operations of Trenwick. Trenwick does not believe, however, that the loss of such business would have a long-term adverse effect because of Trenwick's competitive position within the broker insurance and reinsurance market and the availability of business from other brokers. Underwriting Trenwick's underwriting philosophy emphasizes a transactional approach to underwriting in which any insurance or reinsurance transaction for any line of property or casualty business is considered on its own merits. The underwriter's primary objective is to assess the potential for an underwriting profit. The risk assessment process undertaken by Trenwick's underwriters involves a comprehensive analysis of historical data, when available, and estimates of future value of loss costs which may not be evident in the historical data. The factors which Trenwick considers include the type of risk, details of the underlying insurance coverage provided, adequacy of pricing using actuarial analysis and the terms and conditions. With respect to its domestic operations which comprises fewer but significantly larger accounts, Trenwick frequently conducts underwriting and claims audits of ceding companies to assist it in evaluating the information submitted by the ceding companies, before agreeing to participate in a reinsurance transaction. Trenwick has established formal underwriting policy standards for both domestic and international operations. This process involves pre-binding reviews of individual material transactions by its senior underwriting staff. Underwriting policies for insurance and reinsurance transactions are supplemented by conducting periodic internal audits of each underwriting department to ensure compliance with underwriting policies and procedures. Competition Trenwick competes with numerous major international and domestic insurance and reinsurance companies. These competitors, many of which have substantially greater financial and staff resources than Trenwick, include independent insurance and reinsurance companies, subsidiaries or affiliates of established insurance companies, reinsurance departments of certain commercial insurance companies and underwriting syndicates. Competition in the types of business which Trenwick underwrites is based on many factors. These factors include the perceived overall financial strength of the insurer or reinsurer, rates charged, other terms and conditions, agency ratings (including A.M. Best Company and Standard & Poor's), service offered, speed of service (including claims payment) and perceived technical ability and experience of staff. The number of jurisdictions in which an insurer or reinsurer is licensed or authorized to do business is also a factor. 7 The financial security of insurers and reinsurers has emerged as a key issue throughout the 1990's. To be accepted by clients, and by ceding companies and their brokers, insurers and reinsurers must demonstrate higher levels of financial security and solvency than were previously required. Transactions tend to have fewer and larger participants, which may negatively affect the availability of underwriting opportunities for Trenwick. Trenwick's management believes that the insurance and reinsurance industry, including the broker market, will continue to undergo further consolidation and that size and financial strength will continue to be significant factors in effective competition. Claims Administration Claims are managed by Trenwick's professional claims staff whose responsibilities include the review of initial loss reports, creation of claim files, determination of whether further investigation is required, establishment and adjustment of case reserves and payment of claims. In addition, the claims staff conducts comprehensive claims audits of both specific claims and overall claims procedures at the offices of selected brokers and ceding companies. In certain instances, a claims audit may be performed prior to assuming reinsurance business as part of a comprehensive risk evaluation process. For insurance business, Trenwick's claim staff uses their own judgement as well as advice from lawyers and loss adjusters where appropriate. In connection with the acquisition of Chartwell, Trenwick acquired an environmental claims unit to evaluate the complex toxic tort and latent injury claims resident in one of Chartwell's subsidiaries, The Insurance Corporation of New York. Unpaid Claims and Claims Expenses General Insurers and reinsurers establish claims and claims expense reserves representing estimates of future amounts needed to pay claims and related expenses with respect to insured events which have occurred. Claims and claims expense reserves have two components: case reserves, which are reserves for reported claims, and incurred but not reported ("IBNR") reserves, which are reserves for claims not yet reported. Significant periods of time may elapse between the occurrence of an insured claim, the reporting of the claims to the insurer and the subsequent reporting of the claims to the reinsurer, the insurer's payment of that claim, and later payments by the reinsurer. Trenwick first establishes its case reserves for reported claims when it receives notice of the claim. It is Trenwick's policy to establish reserves for reported claims in an amount equal to the greater of the reserve recommended by the ceding company or the claim as estimated by Trenwick's claims personnel. Trenwick periodically conducts investigations to determine if the amount reserved by the ceding company is appropriate or should be adjusted. During the claim settlement period, which may be many years, additional facts regarding individual claims may become known. As Trenwick learns additional facts, it may become 8 necessary to refine and adjust upward or downward the estimated reserves on a claim, and even then the ultimate net reserve may be less than or greater than the revised estimates. Trenwick does not discount any of its reserves for reported or unreported claims in any line of its business for anticipated investment income. Actuarial Methods Trenwick utilizes the two most common methods of actuarial evaluation used within the insurance industry, the Bornhuetter-Ferguson method and the loss development method. The Bornhuetter-Ferguson method involves the application of selected loss ratios to Trenwick's earned premiums to determine estimates of ultimate expected loss and loss adjustment expenses for each underwriting year. Multiplying expected losses by underwriting year by a selected loss reporting pattern gives an estimate of reported and unreported IBNR losses. When the IBNR is added to the loss and loss adjustment expense amounts with respect to claims that have been reported to date, an estimated ultimate expected loss results. This method provides a more stable estimate of IBNR that is insulated from wide variations in reported losses. In contrast, the loss development method extrapolates the current value of reported losses to ultimate expected losses by using selected reporting patterns of losses over time. The selected reporting patterns are based on historical information (organized into loss development triangles) and are adjusted to reflect the changing characteristics of the book of business written by Trenwick. Trenwick provides capital to its Lloyd's corporate members, which support the underwriting capacity of the Lloyd's syndicates managed by Chartwell Managing Agents. Loss reserves for this business are established using methods similar to those used by Trenwick for its operating insurance company subsidiaries. Chartwell Managing Agents has engaged Bacon & Woodrow London Market Services Ltd. ("B&W"), an independent actuarial consulting firm, to review the loss reserves and prepare an actuarial opinion for each of its syndicates, including the actuarial opinion required by Lloyd's solvency regulations. The B&W opinions, which are prepared solely for the use of Lloyd's regulators and are only to be relied upon by Chartwell Managing Agents, assist its syndicates in establishing appropriate reserve estimates for both the reinsurance to close and the open years of account. In the reserve setting process, Trenwick includes provisions for inflation and "social inflation" if appropriate, as losses are generally not determined until some time in the future. Trenwick continually monitors legislative activity and evaluates the potential effect of any legislative changes on its reserve liabilities. Trenwick's reserves are carried at the full amount estimated for ultimate expected losses and loss adjustment expense without any discount to reflect the time value of money in accordance with both statutory accounting practices and GAAP. Trenwick's actuarial department regularly performs loss reserve analyses for its operating insurance company subsidiaries. 9 Reserve Analysis The following table presents the development of Trenwick's net unpaid claims and claims expenses for 1989 through 1999. The top line of the table shows the net unpaid claims and claims expenses at the balance sheet date for each of the indicated years. This reflects the net estimated amounts of claims and claims expenses for claims arising in that year and in all prior years that are unpaid at the balance sheet date, including claims that had been incurred but not yet reported to Trenwick. The upper portion of the table shows the net cumulative subsequently paid amounts as of successive years with respect to that liability. The middle portion of the table shows the net re-estimated amount of the previously recorded net unpaid claims and claims expenses based on experience as of the end of each succeeding year. The estimates change as more information becomes known about the frequency and severity of claims for individual years. A redundancy (deficiency) exists when the net re-estimated liability at each December 31 is less (greater) than the prior net liability estimate. The net "Cumulative Redundancy (Deficiency)" depicted in the table for any particular calendar year represents the aggregate change in the initial net estimates over all subsequent calendar years. The lower portion of the table presents a reconciliation of the net unpaid claims and claims expenses as of the end of the year with the related gross unpaid claims and claims expenses as of December 31, 1991 through 1999. Additionally, the table presents a reconciliation of the gross re-estimated unpaid claims and claims expenses as of the end of the latest re-estimation year, with separate disclosure of the related re-estimated reinsurance recoverable on unpaid claims and claims expenses. The "gross cumulative redundancy" depicted in the table for the calendar years 1991 through 1999 represents the aggregate change in the initial gross estimates over all subsequent calendar years. 10 DEVELOPMENT OF UNPAID CLAIMS AND CLAIMS EXPENSES (in thousands) - - ---------------------------------------------------------------------------------------------------------------------------------- 1999 1998 1997 1996 1995 1994 1993 1992 - - ---------------------------------------------------------------------------------------------------------------------------------- Net unpaid claims and claims expenses, end of year $1,207,436 $449,264 $ 379,351 $386,887 $327,001 $294,008 $268,091 $266,685 Cumulative amount of net liability paid as of: One year later 172,674 104,718 94,197 46,860 61,804 52,300 52,260 Two years later 194,188 162,565 110,289 81,417 90,382 93,312 Three years later -- 215,803 149,810 121,133 89,445 118,345 Four years later -- -- 178,919 142,485 112,119 111,174 Five years later -- -- -- 156,204 124,096 125,847 Six years later -- -- -- -- 134,535 133,502 Seven years later -- -- -- -- -- 139,779 Eight years later -- -- -- -- -- -- Nine years later -- -- -- -- -- -- Ten years later -- -- -- -- -- -- Net liability re-estimated as of: One year later 463,892 372,176 381,521 322,562 291,943 267,644 255,379 Two years later 383,584 374,336 317,199 279,561 263,473 255,379 Three years later 381,463 308,700 274,283 246,367 252,458 Four years later -- -- 309,282 265,041 241,478 236,009 Five years later -- -- -- 266,583 229,742 230,488 Six years later -- -- -- -- 230,824 222,094 Seven years later -- -- -- -- -- 223,473 Eight years later -- -- -- -- -- -- Nine years later -- -- -- -- -- -- Ten years later -- -- -- -- -- -- Net cumulative redundancy (deficiency) (14,628) (4,233) 5,424 17,719 27,425 37,267 43,212 Percentage (1)% 1% 5% 9% 14% 16% Gross Liability, end of year 682,428 518,387 467,177 411,874 389,298 354,582 351,897 Reinsurance recoverable 233,164 139,036 80,290 84,873 95,290 86,491 85,212 Net liability, end of year 449,264 379,351 386,887 327,001 294,008 268,091 266,685 Gross re-estimated liability-latest 719,143 521,011 462,384 393,765 339,514 293,613 288,355 Re-estimated recoverable-latest 255,251 137,427 80,921 84,483 72,931 62,789 64,882 Net re-estimated liability-latest 463,892 383,584 381,463 309,282 266,583 230,824 223,473 Gross cumulative redundancy (deficiency) (36,715) (2,624) 4,793 18,109 49,784 60,969 63,542 - - -------------------------------------------------------------------------- 1991 1990 1989 - - -------------------------------------------------------------------------- Net unpaid claims and claims expenses, end of year $258,774 $245,105 $214,391 Cumulative amount of net liability paid as of: One year later 44,930 42,234 29,407 Two years later 80,725 77,183 60,888 Three years later 111,225 102,590 84,283 Four years later 127,431 124,129 101,597 Five years later 116,224 134,657 116,047 Six years later 127,130 122,089 124,465 Seven years later 132,194 129,100 110,656 Eight years later 137,401 132,888 115,017 Nine years later -- 136,959 117,364 Ten years later -- -- 120,895 Net liability re-estimated as of: One year later 253,781 238,324 206,724 Two years later 243,488 233,565 199,864 Three years later 243,586 223,417 196,232 Four years later 241,600 224,171 188,052 Five years later 225,592 223,172 189,148 Six years later 217,852 213,327 188,884 Seven years later 208,701 205,179 180,619 Eight years later 211,487 199,948 176,778 Nine years later -- 202,578 172,846 Ten years later -- -- 175,362 Net cumulative redundancy (deficiency) 47,287 42,527 39,029 Percentage 18% 17% 18% Gross Liability, end of year 332,503 Reinsurance recoverable 73,729 Net liability, end of year 258,774 Gross re-estimated liability-latest 268,217 Re-estimated recoverable-latest 56,730 Net re-estimated liability-latest 211,487 Gross cumulative redundancy (deficiency) 64,286 11 In evaluating the information in the table on the preceding page, it should be noted that each amount includes the effects of all changes in amounts for prior periods. For example, if a claim determined in 1991 to be $150,000 was first reserved in 1986 at $100,000, the $50,000 deficiency (actual claim minus original estimate) would be included in the gross cumulative redundancy (deficiency) in each of the years 1986-1991 shown on the preceding page. This table does not present accident or policy year development data. Conditions and trends that have affected the development of liability in the past may not necessarily occur in the future. Accordingly, it may not be appropriate to extrapolate future redundancies or deficiencies based on this table. The trend depicted in the table indicates that net unpaid claims and claims expense liability at December 31, 1998 and 1997 have developed unfavorably due to Trenwick America Re's unfavorable development for claims occurring in accident years 1996 through 1998. For further discussion of unpaid claims and claims expenses, see Note 4 of Notes to the Consolidated Financial Statements of Trenwick. Management believes that Trenwick's reserves are adequate. However, the process of estimating reserves is inherently imprecise and involves an evaluation of many variables, including potentially unpredictable social and economic conditions. Accordingly, there can be no assurance that Trenwick's ultimate liability will not vary significantly from amounts reserved. The inherent uncertainties of estimating such reserves are greater for reinsurers than for primary insurers, primarily due to the longer-term reporting nature of the reinsurance business, the diversity of development patterns among different types of reinsurance, the necessary reliance on ceding companies for information regarding reported claims and differing reserving practices among ceding companies. Reserves also include provisions for latent injury or toxic tort claims that cannot be estimated with traditional reserving techniques. Due to inconsistent court decisions in federal and state jurisdictions and the wide variation among insureds with respect to underlying facts and coverage, uncertainty exists with respect to these claims as to liabilities of ceding companies and, consequently, reinsurance coverage. Management believes that Trenwick's exposure to such latent losses is lessened because of its relatively recent entry into the reinsurance business (other than INSCORP), its low historical levels of premium volume prior to the application of exclusions for asbestos and environmental liabilities, its retrocessional programs and the protection afforded by Trenwick's Contingent Interest Notes due June 30, 2006 (the "Contingent Interest Notes") the payment of which is subject to reduction in the event of such adverse reserve development related to INSCORP's business. Reserves for Trenwick's participation in Lloyd's syndicates through its Lloyd's corporate members are included in the 1999 year end reserves. Part of the reserve represents reinsurance to close balances brought forward to the open years of account (for example, 1996 reinsured into the 1997 open year). Favorable or unfavorable development of the prior year's reserves can influence the results of the open years of 1997, 1998 and 1999. Consequently, there can be no assurance as to the adequacy of reserves and the risk of future developments, both favorable and unfavorable, exists. 12 Trenwick's reserves include an estimate of Trenwick's ultimate liability for asbestos and environmental claims. The gross and net unpaid claims and claims expenses for asbestos and environmental claims are as follows: 1999 1998 1997 - - ------------------------------------------------------------------------------------------------ (in thousands) Unpaid claims and claims expenses gross of reinsurance recoverable, end of year $ 100,131 $ 8,476 $ 8,924 Unpaid claims and claims expenses, net of reinsurance recoverable, end of year 72,092 8,428 8,814 Reinsurance recoverable on unpaid claims and claims expenses, end of year 28,039 48 110 The increase of the gross and net unpaid claims and claims expenses reflect the inclusion of the reserves related to the Chartwell acquisition. Under Trenwick's current interpretation of policy language, management does not believe that it has a material exposure to environmental claims that requires additional reserves beyond its current estimates. Contingent Interest Notes Upon consummation of the acquisition of Chartwell, Trenwick assumed all of Chartwell's obligations under the Contingent Interest Notes, which were originally issued by Piedmont Management Company Inc. to its stockholders just prior to its acquisition by Chartwell in 1995. The Contingent Interest Notes, which mature on June 30, 2006, are designed to provide Trenwick with protection against adverse development of INSCORP's reserves for losses and loss adjustment expenses. In the event there is no adverse development, Trenwick will be required to pay the holders of the CI Notes approximately $55 million in contingent interest. This contingent interest payment is in addition to the $1 million principal amount of the Contingent Interest Notes and interest on such principal amount at 8% per annum (collectively, the "Fixed Amount") which Trenwick in any event must pay at maturity or earlier redemption of the Contingent Interest Notes. In general, assuming the Contingent Interest Notes are settled at maturity, the contingent interest will be equal to $55 million (a) less an amount equal to (i) the amount of any adverse development of the loss and loss adjustment expense reserves and related accounts (including certain reinsurance recoverable, commissions and unearned premiums) of INSCORP recorded as of March 31, 1995, minus (ii) $25 million, (b) plus the amount of certain tax benefits received or recorded by Trenwick as a result of the amount determined pursuant to clause (a) above. The amount so calculated may not be greater than $55 million nor less than a minimum amount equal to the lesser of (a) $10 million less the Fixed Amount and (b) the tax benefits referred to above. In the event that the Contingent Interest Notes are settled prior to maturity, the foregoing formula will in general apply, except that the $55 million maximum amount of the Contingent Interest Notes will be reduced to an amount equal to $55 million discounted back from June 30, 2006 at a discount rate of 8% per annum, compounded annually, and the tax benefits will be calculated in a prescribed manner. The carrying value of the Contingent Interest Notes on Trenwick's consolidated financial statements at December 31, 1999 was $34.7 million, representing the sum of the aggregate principal amount of the Contingent Interest Notes and the present value as of such date of the maximum amount of contingent interest payable on the Contingent Interest Notes at their stated maturity in 2006. During the term of the Contingent Interest Notes, the discounted carrying value of the Contingent Interest Notes will be increased to reflect accretion of (i) interest on the principal amount and (ii) the discounted contingent interest. To the 13 extent that adverse development of INSCORP's reserves (including IBNR reserves) occurs prior to the maturity or redemption of the Contingent Interest Notes, the contingent interest payable on the Contingent Interest Notes (and, therefore, the then-current carrying value of such Contingent Interest Notes) will be reduced. Such reductions in the carrying value of the Contingent Interest Notes would offset in part, in the period in which such adverse development occurs, any reduction in Trenwick's GAAP net income and stockholders' equity resulting from such adverse reserve development (that would, however, still be reflected in Trenwick's statutory underwriting results and in the policyholders' surplus of INSCORP and any parent insurer of INSCORP). At its option, Trenwick may settle the Contingent Interest Notes with shares of common stock of Trenwick instead of payment of cash. For purposes of settlement of the Contingent Interest Notes, such common stock would be valued at 85% of its average closing market price over a specified period prior to the settlement date. However, Trenwick may not settle the Contingent Interest Notes in its common stock unless (i) such stock is registered under the Securities Act of 1933 (or is otherwise freely tradeable other than by certain affiliates of Trenwick), (ii) such stock is listed on a national securities exchange or the NASDAQ National Market and (iii) all Contingent Interest Notes are settled in such common stock. Moreover, Trenwick may not settle the Contingent Interest Notes in its common stock if the Contingent Interest Notes are being settled following acceleration thereof due to an event of default under the Contingent Interest Notes. Reinsurance and Retrocessional Agreements Trenwick enters into reinsurance and retrocessional agreements to reduce its net liability on individual risks, protect against catastrophic losses and maintain acceptable ratios. Trenwick America Re has various retrocessional facilities, all of which are on a treaty basis. These retrocessional facilities include one treaty for Trenwick America Re's facultative casualty reinsurance business, which applies on a risk or account basis, and two for its treaty property business, which protect it against multiple claims arising out of a single occurrence or event. As a result of these facilities, Trenwick America Re's maximum retention generally does not exceed $500,000 per occurrence on facultative business and $2,300,000 per occurrence on property catastrophe business. From 1989 to 1999, Trenwick America Re has purchased aggregated excess of loss ratio treaties from several reinsurers. These facilities provided Trenwick with a layer of protection against adverse results from its domestic casualty business in excess of specified loss ratios. Trenwick did not purchase an aggregate excess of loss ratio treaty for 2000. Trenwick International, as customary with companies operating in the London market, buys large amounts of reinsurance. Reinsurance and retrocessional coverage is customized for each class of business. During 1998, following an increase in its share capital, Trenwick International increased its retention of business by reducing the amount of reinsurance it buys, principally proportional reinsurance treaties with its former parent. Chartwell Managing Agency, as part of its business strategy, has historically purchased a significant amount of reinsurance for the Lloyd's syndicates it manages. Reinsurance is generally purchased to protect the syndicates against extraordinary loss or loss involving one or more underwriting classes. The amount purchased is determined with reference to the syndicates' aggregate exposure and potential loss scenarios. Canterbury Financial Group purchases reinsurance specifically tailored to each of the specialty programs underwritten by its insurance subsidiaries. 14 In connection with the acquisition of Chartwell by Trenwick, Chartwell's insurance company subsidiaries purchased an aggregate excess of loss reinsurance agreement providing up to $100 million in coverage against unanticipated increases in Chartwell's reserves for business written on or before October 27, 1999, the date of completion of the acquisition of Chartwell. Within the $100 million maximum, the protection is limited to $100 million for increased reserves attributable to Chartwell's Lloyd's operations, $25 million for increased reserves attributable to catastrophe and year 2000 losses and $50 million for increased reserves attributable to asbestos and environmental coverage losses. The aggregate excess of loss reinsurance agreement is not cancelable by the reinsurers, London Life and Scandanavian Re and their obligations have been secured by a trust account. The premium payable for this aggregate excess of loss reinsurance agreement was approximately $56 million. Trenwick remains liable with respect to insurance and reinsurance ceded in the event that the insurer or retrocessionaire is unable to meet its obligations. All reinsurers and retrocessionaires must be formally approved by the operating company's Security Committee. The Security Committees re-evaluate the financial condition of Trenwick reinsurers and retrocessionaires at least annually. The evaluation process involves financial analysis of current audited financial data and comparative analysis of such data in accordance with guidelines established by Trenwick. Business may not be conducted with retrocessionaires who are not currently approved by the Security Committees. Trenwick America Re's principal retrocessionaires are Zurich Reinsurance, Continental Casualty Company, Unum Life Insurance Company of America and National Union Fire Insurance Company. Chartwell Re's principal retrocessionaires are Centre Reinsurance (Bermuda) Limited and London Life and Casualty Reinsurance Corp. and Scandinavian Reinsurance Company Limited. INSCORP's largest reinsurers in 1999 were American Reinsurance company, Navigators Insurance Company and European International Reinsurance Company Limited. Trenwick International has two principal retrocessionaires, Lloyds of London and Transatlantic Re. All these retrocessionaires are rated A (Excellent) or better by A.M. Best Company. At December 31, 1999, Trenwick had no material uncollectible amounts due from its retrocessionaires. Investments The Investment Committee of Trenwick's Board of Directors oversees investments and sets procedures and guidelines for investment strategy. Trenwick's internal staff manage these investments and utilize the services of investment advisers. Trenwick's investment strategy focuses on capital preservation and income predictability. This strategy also requires that the risks associated with these objectives are properly managed. Accordingly, Trenwick emphasizes investment grade debt investments. At December 31, 1999, 79% of Trenwick's investments in debt securities were rated Aa or better. In October 1998, certain securities had their ratings withdrawn by various nationally recognized statistical rating organizations. The servicer of these securities, Commercial Financial Services, Inc., filed for protection under Chapter 11 of the Federal Bankruptcy Code in December 1998. During 1999, Trenwick wrote down the value of these securities by $5.2 million. Trenwick's investment strategy permits an allocation for equity securities. At December 31, 1999, 6% of Trenwick's total investments and cash were invested in common and preferred equities, which consist primarily of securities issued by U.S. and United Kingdom corporations. The primary risk associated with these securities is the exposure to daily market fluctuations. 15 The investments of each of Trenwick's insurance company subsidiaries must comply with the respective insurance laws of the jurisdiction of domicile of that insurance company, and of the other jurisdictions in which it is licensed or authorized. These laws prescribe the kind, quality and concentration of investments which may be made by insurance companies. In general, these laws permit investments, within specified limits and subject to certain qualifications, in federal, state and municipal obligations, corporate bonds, preferred and common stock, real estate mortgages and real estate. These laws generally penalize high concentrations of riskier types of assets and high exposures to certain types of issuers. Trenwick invests in three types of structured securities, collateralized mortgage obligations ("CMO"), mortgage-backed securities not backed by U.S. government agencies ("non-agency MBS") and asset-backed securities ("ABS"), each accounting for 5%, 5% and 2%, respectively, of Trenwick's portfolio at December 31, 1999. CMOs consist of planned amortization classes ("PACs") which have been constructed with a certain amount of call protection and CMOs that have lost their PAC protection (sometimes called "broken" or "busted" PACs), due to actual prepayments being significantly higher or lower than originally forecast. These agency backed CMOs are not subject to credit risk, as all holdings are backed indirectly or directly by the Federal government or one of its agencies. The material risk inherent to holding these CMOs is prepayment risk, which relates to the timing of cash flows that result from amortization, whether it accelerated, because of lower interest rates and therefore higher than expected prepayments, or decelerated, because of higher interest rates and therefore lower than expected prepayments. Changes in principal repayments could negatively affect investment income due to the timing of the reinvested funds. Non-agency MBSs are constructed primarily from the securitization of mortgages on commercial or residential real estate and, lacking any agency backing, are inherently subject to credit risk. They also have an element of prepayment risk which is contingent on the structure of each security and its underlying collateral. 93% of the non-agency MBS issues Trenwick has purchased have a rating of A or better from various Nationally Recognized Statistical Rating Organizations. The asset-backed securities owned by Trenwick have primarily credit card and home equity receivables as collateral and are subject also to credit risk. These securities have less cash flow uncertainty than non-agency MBS and CMO issues, because the issuer has the ability to add in new collateral should the asset-backed security experience faster prepayments, or in the event of default on the underlying collateral. 94% of the asset-backed securities owned by Trenwick are rated A or better by various Nationally Recognized Statistical Rating Organizations. The remaining 6% include the asset-backed securities serviced by Commercial Financial Services, Inc. for which ratings have been withdrawn. Trenwick also invests in agency pass-through securities which account for 7% of Trenwick's portfolio at December 31, 1999. As with CMOs, these securities are subject to prepayment risk. Trenwick holds debt securities and cash in a number of currencies. At December 31, 1999, approximately 16% of Trenwick's debt securities and cash were held in U.K. sterling, and the remainder in six other currencies. 16 The table below sets forth the distribution of Trenwick's investments available for sale at December 31, 1999 by type, maturity and quality rating.

Ratings are generally assigned upon the issuance of the securities, subject to revision on the basis of ongoing evaluations. 18 Regulation Trenwick and its insurance company subsidiaries are subject to regulatory oversight under the insurance statutes and regulations of the jurisdictions in which they conduct business, including all states of the United States and the United Kingdom. These regulations vary from jurisdiction to jurisdiction and are generally designed to protect ceding insurance companies and policyholders by regulating Trenwick's financial integrity and solvency in its business transactions and operations. Many of the insurance statutes and regulations applicable to Trenwick's subsidiaries relate to reporting and enable regulators to closely monitor Trenwick's performance. Typical required reports include information concerning Trenwick's capital structure, ownership, financial condition, and general business operations. Trenwick International is subject to the regulatory authority of the United Kingdom Financial Services Authority. Both Chartwell Managing Agents and Trenwick's dedicated Lloyd's underwriting entities, as a Lloyd's managing general agent and Lloyd's corporate members, respectively, are subject to regulation and supervision by the Council of Lloyd's. Lloyd's operates under a self-regulatory regime under the Lloyd's Act 1982 and has the power to set, interpret and change the rules which govern the operation of the Lloyd's market, subject to regulation for solvency purposes by the Financial Services Authority. Lloyd's prescribes, in respect of its managing agents and corporate members, certain minimum standards relating to their management and control, solvency and various other requirements. In addition, Lloyd's imposes restrictions against persons becoming controllers and major shareholders of managing agents and corporate members without the consent of Lloyd's first having been obtained. The United Kingdom government has established the Financial Services Authority as a single regulator to supervise securities, banking and insurance business, including Lloyd's. When the Financial Services and Market Bill becomes law, probably in late 2000, the Financial Services Authority will have wide authorization and intervention powers in relation to Lloyd's. A consultation process has commenced in relation to Lloyd's regulatory framework. NAIC The National Association of Insurance Commissioners ("NAIC") is an organization which assists state insurance supervisory officials in achieving insurance regulatory objectives, including the maintenance and improvement of state regulation. From time to time various regulatory and legislative changes have been proposed in the insurance industry, some of which could have an effect on reinsurers. Among the proposals that have in the past been or are at present being considered are the possible introduction of federal regulation in addition to, or in lieu of, the current system of state regulation of insurers, and proposals in various state legislatures (some of which proposals have been enacted) to conform portions of their insurance laws and regulations to various model acts adopted by the NAIC. Trenwick is unable to predict what effect, if any, these developments may have on its operations and financial condition. See Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations. Risk Based Capital The NAIC has adopted Risk-Based Capital ("RBC") requirements for property and casualty insurance companies to evaluate the adequacy of statutory capital and surplus in relation to investment and insurance risks such as asset quality, asset and liability matching, loss reserve adequacy and other business factors. The RBC formula is used by state insurance regulators as an early warning tool to identify, for the purpose of initiating regulatory action, insurance companies that potentially are inadequately capitalized. In addition, the formula defines minimum capital standards that supplement the system of low fixed minimum capital and surplus requirements on a state-by-state basis. Regulatory compliance is determined by a ratio of the enterprise's regulatory total adjusted capital to its authorized control level RBC, as defined by the NAIC. Enterprises below specific trigger points or ratios are classified within certain levels, each of which 19 requires specific corrective action. The ratios of Total Adjusted Capital to Authorized Control Level RBC for each of Trenwick's United States insurance company subsidiaries exceeded all the RBC trigger points at December 31, 1999, 1998 and 1997. State Insurance Regulation The premium rates and policy terms of Trenwick's reinsurance agreements generally are not subject to regulation by any government authority. This contrasts with Trenwick's property and casualty insurance operations where the premium rates and policy terms are generally closely regulated by state insurance departments. As a practical matter, however, the premium rates charged by insurers may place a limit on the rates which can be charged by reinsurers. The regulation and supervision to which Trenwick's insurance subsidiaries are subject relate primarily to the standards of solvency that must be met and maintained, licensing requirements for reinsurers, the nature of and limitations on investments, restrictions on the size of risks which may be insured, deposits of securities for the benefit of insureds or reinsureds, methods of accounting, periodic examinations of the financial condition and affairs of reinsurers, the form and content of reports of financial condition required to be filed, and reserves for unearned premiums, losses and other purposes. In general, such regulation is for the protection of the insureds and reinsureds, rather than Trenwick's security holders. Trenwick believes that it is in compliance with all such material regulations. Trenwick is subject to regulation under the insurance statutes and insurance holding company statutes of various states, including Connecticut, New York and North Dakota, the domicile states of its U.S. insurance companies. These laws and regulations vary from state to state, but generally require an insurance holding company, and insurers and reinsurers that are subsidiaries of an insurance holding company, to register with the state regulatory authorities and to file with those authorities certain reports including information concerning their capital structure, ownership, financial condition and general business operations. State laws also require prior notice or regulatory agency approval of direct or indirect changes in control of an insurer, reinsurer or its holding company and of certain significant intercorporate transfers of assets within the holding company structure. An investor who acquires securities representing or convertible into more than 10% of the voting power of the securities of Trenwick would become subject to at least some of such regulations and would be subject to approval by the Connecticut, New York and North Dakota Insurance Commissioners prior to acquiring such shares. Such investor would also be required to file certain notices and reports with the Insurance Commissioners prior to such acquisition. Codification of Statutory Accounting Principles In March 1998, the NAIC adopted the Codification of Statutory Accounting Principles ("Codification"). The Codification, which is intended to standardize regulatory accounting and reporting for the insurance industry, is proposed to be January 1, 2001. The Codification provides guidance for areas where statutory accounting has been silent and changes current statutory accounting in some areas. However, statutory accounting principles will continue to be established by individual state laws and permitted practices. Effective January 1, 2001, the states of Connecticut (domicile of Trenwick America Re), Minnesota (domicile of Chartwell Reinsurance), New York (domicile of INSCORP and ReCor) and North Dakota (domicile of Dakota) will adopt the Codification. It is uncertain what effect adoption of the Codification for the preparation of statutory financial statements would have on those statutory financial statements. 20 Dividends Because Trenwick's operations are conducted through its operating subsidiaries, Trenwick is dependent upon the ability of its operating subsidiaries, to transfer funds, principally in the form of cash dividends, tax reimbursements and other statutorily permissible payments. In addition to general legal restrictions on payments of dividends and other distributions to shareholders applicable to all corporations, Trenwick's insurance subsidiaries are subject to further regulations that, among other things, restrict the amount of dividends and other distributions that may be paid to their parent corporations. Under the applicable provisions of the insurance holding company laws of the states of domicile of Trenwick America Re, Chartwell Reinsurance and Dakota, such companies may only pay dividends without the approval of the applicable state insurance regulator, if such dividends, together with other dividends paid within the preceding twelve months, are less than the greater of (i) 10% of the insurer's policyholders' surplus as of the end of the prior calendar year or (ii) the insurer's statutory net income, excluding realized capital gains, for the prior calendar year. As a further restriction, the maximum amount of dividends most U.S. insurers may pay is limited to its earned surplus, also known as its unassigned funds. Any dividend in excess of the amount determined pursuant to the foregoing formula would be characterized as an "extraordinary dividend" requiring the prior approval of the state insurance regulator. Under New York law, which is applicable to INSCORP and ReCor Insurance Company Inc. ("ReCor") the maximum ordinary dividend payable in any twelve month period without the approval of the New York Insurance Department is the lesser of (i) 10% of policyholders surplus as shown on the company's last annual statement or any more recent quarterly statement or (ii) the company's adjusted net investment income. Adjusted net investment income is defined as net investment income for the twelve months preceding the declaration of the dividend plus the excess, if any, of net investment income over dividends declared or distributed during the period commencing thirty-six months prior to the declaration or distribution of the current dividend and ending twelve months prior thereto. In any case, New York law permits the payment of an ordinary dividend by an insurer or reinsurer only out of earned surplus. In addition to the foregoing limitations, the New York Insurance Department, as is its practice in any change of control situation, required Trenwick to commit to preclude the acquired New York-domiciled insurers, INSCORP and ReCor, from paying any dividends for two years after the merger with Chartwell without prior regulatory approval. The foregoing restriction will expire on October 27, 2001. Neither INSCORP nor ReCor paid any dividends in 1997, 1998 or 1999. Moreover, insurance holding company laws generally provide that, notwithstanding the receipt of any dividend from a subsidiary insurer, an insurer may make dividend payments to its parent only to the extent it is permitted to do so under its applicable dividend restrictions. In other words, the ability of a subsidiary insurer to pay dividends without restriction may be impaired if its parent insurer cannot pay dividends without restriction. The maximum dividend permitted by law may not be indicative of an insurer's actual ability to pay dividends, which may be constrained by business and other regulatory considerations, such as the impact of dividends on surplus, which could affect an insurer's ratings or competitive position, the amount of premiums that can be written and the ability to pay future dividends. Furthermore, beyond the limits described in the preceding paragraph, insurance regulatory authorities often have the discretion to limit the payment of dividends by insurance companies domiciled in their jurisdictions. In 2000, of Trenwick's U.S. insurance subsidiaries, only Dakota could pay a dividend or other distribution without prior approval of the applicable insurance regulatory authority. In 2000, Dakota Specialty could pay a dividend of $2.8 milion without prior approval. During 1999, 1998 and 1997, Trenwick America Re paid dividends of $53.4 million, $30.1 21 million and $8.3 million,respectively. Chartwell Reinsurance paid dividends of $30.3 million in 1999 and $3.0 million in 1997. Chartwell Reinsurance did not pay any dividends in 1998. None of Trenwick's other U.S. insurance subsidiaries paid any dividends in 1999, 1998 or 1997. Under the applicable laws of the United Kingdom, Trenwick's U.K. subsidiaries may make shareholder distributions only from accumulated realized profits, net of accumulated realized losses. In addition, under the UK Insurance Companies Act, Trenwick International is not permitted to make any distribution that would reduce its net assets below the required minimum margin of solvency which, as determined under the U.K. Financial Service Authority's rules, is approximately $16.7 million as of December 31, 1999. Trenwick International must also notify the United Kingdom Financial Services Authority of any proposal to declare or pay a dividend on any of its share capital. Under Lloyd's regulations, Chartwell Managing Agents is not permitted to make any distribution that would cause its assets to fall below any of Chartwell Managing Agents' share capital, minimum net current asset margin or minimum net asset margin. As of December 31, 1999, the highest of the three tests required Chartwell Managing Agents to maintain approximately $1.1 million of capital. Investment Limitations Connecticut, New York and North Dakota laws and regulations govern the types and amounts of investments which are permissible for Trenwick's insurance company subsidiaries. These rules are designated to ensure the safety and liquidity of the insurers' investment portfolio. In general, these rules permit insurers to purchase only investments which are interest bearing, interest accruing, entitled to dividends or otherwise income earning and not then in default in any respect, and insurers must be entitled to receive for its exclusive account and benefit the interest or income accruing thereon. No security or investment is eligible for purchase at a price above its fair value or market value. In addition, these rules require investments by Trenwick to be diversified. The U.K. Financial Services Authority governs the types and amounts of investments which are permissible for insurers in the United Kingdom, including Trenwick International. Likewise, Lloyd's regulations govern the types and amounts of investments that are permissible for Chartwell Managing Agents to make with the assets of the Lloyd's syndicates that it manages. These laws penalize high concentrations of riskier types of assets and high exposures to certain types of issuers. Trenwick believes that it is in compliance with all material applicable investment laws. Employees At December 31, 1999, Trenwick employed a total of 124 and 284 persons in its domestic and international operations, respectively. Trenwick has no employees represented by a labor union and believes that its employee relations are good. Item 2. Properties Trenwick's corporate headquarters and Trenwick America Re's offices are located in approximately 46,000 total square feet of leased office space at One Canterbury Green, Stamford, Connecticut. In connection with the acquisition of Chartwell, Trenwick assumed a lease of approximately 53,000 square feet of space at Four Stamford Plaza in Stamford, Connecticut. Chartwell Managing Agents leases approximately 39,000 square feet of space in London, England and Trenwick International leases office space in London, England and Paris, France. Management believes Trenwick's current office space is adequate for its needs. See Note 8 of Notes to the Consolidated Financial Statements of Trenwick. 22 Item 3. Legal Proceedings Trenwick is party to various legal proceedings generally arising in the normal course of its business. Trenwick does not believe that the eventual outcome of any such proceeding will have a material effect on its financial condition or business. Trenwick's subsidiaries are regularly engaged in the investigation and the defense of claims arising out of the conduct of their business. Pursuant to Trenwick's insurance and reinsurance arrangements, disputes are generally required to be finally settled by arbitration. Item 4. Submission of Matters to a Vote of Security Holders A special meeting of stockholders of Trenwick was held in Old Greenwich, Connecticut on October 7, 1999. Shareholders holding 8,680,216 shares of Trenwick's common stock, 82.8% of the then outstanding shares, were represented in person or by proxy. The proposal to adopt the merger agreement between Trenwick and Chartwell and approve the merger of Chartwell with and into Trenwick and the issuance of Trenwick common stock to Chartwell stockholders upon completion of the merger was approved: 7,881,754 shares voted in favor; 7,884 shares voted against; and 1,155 shares abstained (including broker non-votes). The proposal to amend Trenwick 1993 Stock Option Plan to increase the aggregate number of shares of Common Stock subject to awards under such plan by 125,000 shares was approved: 7,584,123 shares voted in favor; 294,381 shares voted against; and 801,712 shares abstained (including broker non-votes). 23 PART II Item 5.
