Business General Background and History Trenwick Group Ltd., is a holding company whose principal subsidiaries underwrite specialty insurance and reinsurance. Trenwick Group Ltd. was formed as a Bermuda company in 1999 to acquire two publicly held companies, Trenwick Group Inc. and LaSalle Re Holdings Limited, and the minority interest in LaSalle Re Limited, a subsidiary of LaSalle Re Holdings Limited. That transaction, in which Trenwick Group Ltd. issued common shares to acquire LaSalle Re Holdings Limited, Trenwick Group Inc. and the minority interest in LaSalle Re Limited, was completed on September 27, 2000 and was accounted for as a purchase by LaSalle Re Holdings Limited. Accordingly in the financial statements, the assets and liabilities and the revenues and expenses of LaSalle Re Holdings Limited were included for all periods presented; the minority interest in common shares and minority interest in net income of LaSalle Re were eliminated as of September 30, 2000 and from October 1, 2000, respectively, and the assets and liabilities and the revenues and expenses of Trenwick Group Inc. were included as of September 30, 2000 and from October 1, 2000, respectively. Trenwick Group Inc. had earlier acquired another publicly held company, Chartwell Re Corporation, on October 27, 1999. Each of Trenwick Group Ltd.'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 Limited's syndicates enjoy the benefit of the ratings of Lloyd's, which is rated "A-" (Excellent) by A.M. Best Company and has an A financial strength 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. Business Segment Information Trenwick Group Ltd. conducts its specialty insurance and reinsurance business in the following five business segments: o Worldwide property catastrophe reinsurance; o United States treaty reinsurance; o International specialty insurance and reinsurance; o Lloyd's insurance and reinsurance; and o United States specialty program insurance. Trenwick Group Ltd. operates through the following five principal operating platforms: o LaSalle Re Limited, which is located in Hamilton, Bermuda, underwrites property catastrophe reinsurance on a worldwide basis; o Trenwick America Reinsurance Corporation, which is located in Stamford Connecticut, underwrites treaty reinsurance on United States property and casualty risks, including United States reinsurance business previously written by Chartwell Re Corporation's subsidiaries; o Trenwick International Limited, which is located in London, England, underwrites specialty insurance and facultative reinsurance on a world wide basis; o Chartwell Managing Agents Limited, which is located in London, England, manages underwriting syndicates in the Lloyd's market, principally for Trenwick Group Ltd.'s own account; and 1 o Canterbury Financial Group Inc., which is located in Stamford, Connecticut, underwrites specialty insurance in the United States through its operating subsidiaries, Chartwell Insurance Company, The Insurance Corporation of New York and Dakota Specialty Insurance Company. The table below presents gross and net premium writings by business segment as though Trenwick Group Inc. and LaSalle Re Holdings Limited had combined as of January 1, 1999. Thus, the full calendar year premium writings for LaSalle Re Holdings Limited and Trenwick Group Inc. are included for each period presented, including the premium writings of Chartwell Re Corporation's subsidiaries from October 27, 1999, the date Trenwick Group Inc. acquired Chartwell Re Corporation. The amounts presented in the table are different from gross and net premium writings in Trenwick Group Ltd.'s consolidated financial statements because LaSalle Re Holdings Limited was determined to be the accounting acquiror in the Trenwick/LaSalle business combination. Accordingly, the consolidated financial statements of Trenwick Group Ltd. include the premium writings of LaSalle Re Holdings Limited for all periods presented and include the premium writings of Trenwick Group Inc. from September 27, 2000, the date of the Trenwick/LaSalle business combination. 2001 2000 1999 ---------- ---------- -------- (expressed in thousands of United States dollars) Gross Premiums Written - ---------------------- Worldwide property catastrophe reinsurance $ 138,173 $ 101,026 $115,485 U.S. treaty reinsurance 339,257 338,794 210,921 International specialty insurance and reinsurance 234,966 231,062 171,698 Lloyd's syndicates - continuing 443,977 351,229 74,336 Lloyd's syndicates - runoff 4,449 36,794 32,519 U.S. specialty program insurance 291,433 187,545 38,088 ---------- ---------- -------- Total $1,452,255 $1,246,450 $643,047 ========== ========== ======== Net Premiums Written - -------------------- Worldwide property catastrophe reinsurance $ 89,509 $ 76,289 $ 97,129 U.S. treaty reinsurance 319,145 251,830 165,744 International specialty insurance and reinsurance 191,875 180,600 129,399 Lloyd's syndicates - continuing 264,270 245,738 55,859 Lloyd's syndicates - runoff 3,047 25,467 20,875 U.S. specialty program insurance 102,472 54,028 5,641 ---------- ---------- -------- Total $ 970,318 $ 833,952 $474,647 ========== ========== ======== The following discussion of segments addresses changes in gross and net premium writings as presented in the table above. For additional financial information regarding Trenwick Group Ltd.'s business segments, see note 3 to Trenwick Group Ltd.'s consolidated financial statements. Worldwide Property Catastrophe Reinsurance Catastrophe reinsurance contracts cover unpredictable events such as hurricanes, windstorms, hailstorms, earthquakes, fires, industrial explosions, freezes, riots, floods and other man-made or natural disasters. These contracts are written on an excess of loss and a pro rata basis. The largest portion of Trenwick Group Ltd.'s property catastrophe business consists of excess of loss contracts. Property catastrophe excess of loss reinsurance provides coverage when total losses and loss expenses from a single occurrence of a covered peril under a portfolio of primary insurance contracts exceed the attachment point specified in the reinsurance contract with the primary insurer. 2 Trenwick Group Ltd. also writes property catastrophe pro rata reinsurance treaties. In these programs, Trenwick Group Ltd. assumes a specified proportion of the exposure under a portfolio of excess of loss property catastrophe reinsurance contracts written by the ceding reinsurer and receives an equal proportion of the premium received by the cedent. Trenwick Group Ltd.'s worldwide property catastrophe segment's principal underwriting strategy is to underwrite property catastrophe exposures within clearly defined parameters that permit thorough analysis and appropriate pricing of each reinsurance contract. In many cases, this includes analysis of a reinsurance contract based on the expected incremental return on equity in relation to the segment's overall portfolio of reinsurance contracts. Because Trenwick Group Ltd. underwrites property catastrophe reinsurance and has large aggregate exposures to natural and man-made disasters, Trenwick Group Ltd.'s claims experience in its worldwide property catastrophe reinsurance segment generally will involve infrequent events of great severity. Trenwick Group Ltd. seeks to diversify its reinsurance portfolio to moderate the impact of this severity. The principal means of diversification are by geographic coverage and by varying attachment points and imposing coverage limits per program. Trenwick Group Ltd. also establishes zonal accumulation limits to avoid concentrations of risk within particular geographic areas. Trenwick Group Ltd.'s worldwide property catastrophe segment uses computer-based modeling systems to estimate exposure to loss and evaluate pricing adequacy of its reinsurance programs. These models are also used in the analysis of projected return on equity and the monitoring of aggregate exposures within geographic zones. U.S. Treaty Reinsurance Trenwick Group Ltd.'s U.S. treaty reinsurance segment underwrites United States treaty reinsurance. This segment 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 Group Ltd.'s U.S. treaty reinsurance segment 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. The U.S. treaty reinsurance segment's commitment is currently limited to $3.0 million per contract on casualty treaty business and $2.5 million on property business. Larger commitments are subject to Trenwick Group Ltd.'s underwriting committee referral process. The major lines of reinsurance currently underwritten by the U.S. treaty reinsurance segment are accident and health, property, errors and omissions, environmental liability and general liability. Together these lines accounted for an aggregate of at least 65% of its net premiums written in each of 2001, 2000 and 1999. Trenwick Group Ltd.'s U.S. treaty reinsurance segment also underwrites medical malpractice, workers' compensation, products liability and automobile liability lines of reinsurance. 3 Three ceding companies generated a majority of the U.S. treaty reinsurance business shown on the table on page 2, accounting for 22%, 31% and 25% of this segment's gross premiums written in 2001, 2000 and 1999, respectively. During 2001, Travelers Group, Avemco Group and American International Group accounted for 9%, 7% and 6%, respectively, of the segment's gross premiums written. Trenwick Group Ltd. does not believe that the loss of these accounts would have a long-term material adverse effect on the results and operations of the U.S. treaty reinsurance segment because of its competitive position within the reinsurance market and the availability of business from other brokers and ceding companies. Further, Trenwick Group Ltd. believes that this segment would continue to underwrite new business to replace the accounts. International Specialty Insurance and Reinsurance Trenwick Group Ltd.'s international specialty insurance and reinsurance segment's business consists principally of insurance and facultative reinsurance of specialty classes as well as property and casualty treaty reinsurance. Treaty reinsurance includes liability business, which accounted for approximately 40% of treaty business in 2001, as well as property and credit business. Treaty is written both on a proportional and non-proportional basis. Effective January 1, 2002, the international specialty insurance and reinsurance platform's property and casualty treaty reinsurance will be underwritten in Trenwick Group Ltd.'s Lloyd's operation. The international specialty insurance and reinsurance segment obtains all of its business through brokers, and consists of specialist risk underwriting, which includes direct insurance and facultative reinsurance, and treaty reinsurance. Specialist risk business is underwritten in both London and Paris. The principal lines of business underwritten include property, engineering, latent defects, professional indemnity, financial institutions, liability, extended warranty, credit and bonds and general aviation. In 2001, approximately 59% of Trenwick International Limited's gross premiums were written directly as insurance. Trenwick Group Ltd.'s Paris branch specializes in large, complex property risks that require a high degree of underwriting expertise. The international specialty insurance and reinsurance segment 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. The Paris branch also underwrites cargo insurance. Lloyd's Syndicates Trenwick Group Ltd. participates in the Lloyd's market principally through Chartwell Managing Agents Limited, which is a managing agent at Lloyd's and through five Lloyd's corporate members. Chartwell Managing Agents Limited 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 2002 year of account, Chartwell Managing Agents Limited manages three syndicates with a total underwriting capacity of approximately $329.5 million, which is primarily supplied by Trenwick Group Ltd. Classes of business covered by Chartwell Managing Agents Limited's syndicates include marine, property, non-marine liability, aviation and life. 4 In 1998 and 1999, Chartwell Managing Agents Limited 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. These remaining non-life syndicates included property, marine, aviation and non-marine liability segments. Trenwick Group Ltd. 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, and has classified these results as Lloyd's runoff. In conjunction with the sale of syndicate 866, Trenwick Group Ltd. purchased a reinsurance to close cover which terminated any further exposure to that syndicate. LaSalle Re Limited provided capital support through a subsidiary to three Lloyd's syndicates for the 2000 and 1999 underwriting years of approximately $14.6 million and $31.9 million, respectively. Following the Trenwick/LaSalle business combination, LaSalle Re Limited withdrew its capital support for the 2001 underwriting year. This decision is in line with Trenwick Group Ltd.'s strategy of returning LaSalle Re Limited to its core business of property catastrophe reinsurance. The Lloyd's business written on behalf of LaSalle Re Limited has been classified as Lloyd's runoff. U.S. Specialty Program Insurance U.S. specialty program insurance, written through Canterbury Financial Group Inc.'s insurance companies, 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 Inc. evaluates each business relationship based upon the underwriting experience and operational expertise of the production source and periodically performs underwriting, claims and operational audits of each of its production sources. During the 2001 calendar year, the U.S. specialty program insurance segment underwrote approximately 68% of the gross premiums ascribed to it in the table on page 2 through four managing general agents, of which Florida Intracoastal Underwriters accounted for 27%, HDR Insurance Services accounted for 16%, Inter-Reco accounted for 14% and Risk Control Services accounted for 11%. The Inter-Reco casualty program was non-renewed in October of 2001. No other managing general agent accounted for more than 10% of the specialty program insurance segment'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, Trenwick Group Ltd. 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 the U.S. specialty program insurance segment. Marketing Each of Trenwick Group Ltd.'s business segments 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. 5 Trenwick Group Ltd. pays such intermediaries or brokers commissions representing negotiated percentages of the premium it writes. These commissions constitute part of Trenwick Group Ltd.'s total acquisition costs and are included in its underwriting expenses. Under certain limited circumstances, selected administrators have the authority to bind a portion of Trenwick Group Ltd. business. These administrators are subject to periodic financial and operational reviews. Trenwick Group Ltd. 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 Group Ltd. During 2001, five brokers generated 51% of the gross written premiums reflected in the table on page 2. Aon Reinsurance Agency accounted for 19%, Marsh and MacLennan accounted for 16%, Reinsurance Alternatives accounted for 8%, Heath Lambert accounted for 6%, and Benfield Blanch accounted for 2% of those gross written premiums. During the 2000 year, the 1999 period and the 1999 year, Marsh and MacLennan provided 13%, 40%, and 20% of the gross written premiums reflected in Trenwick Group Ltd.'s consolidated financial statements, respectively, and Aon Reinsurance Agency provided 18%, 4%, and 18%, respectively. Loss of all or a substantial portion of the business provided by these brokers could have a material adverse effect on the business and operations of Trenwick Group Ltd. or one or more of its business segments. Trenwick Group Ltd. does not believe, however, that the loss of such business would have a long-term adverse effect because of Trenwick Group Ltd.'s competitive position within the reinsurance market and the availability of business from other brokers. Geographic Information Trenwick Group Ltd. seeks to diversify its insurance and reinsurance exposures across geographic zones in order to optimize its spread of risk. The following table presents Trenwick Group Ltd.'s gross premiums written as included in its consolidated financial statements for the years ended December 31, 2001 and 2000, the three month period ended December 31, 1999 and the year ended September 30, 1999 allocated to the geographic region in which the risks originate: 2001 Year 2000 Year 1999 Period 1999 Year ---------- --------- ----------- --------- Gross premiums written: (amounts in thousands of United States dollars) United States $ 797,262 $205,819 $ 719 $ 60,074 United Kingdom 317,895 115,273 3,337 32,161 Europe, excluding United Kingdom 133,762 20,429 -- 9,555 Australia, New Zealand and Far East 31,578 13,934 647 7,383 Worldwide 171,758 73,189 5,604 29,837 ---------- -------- ------- -------- Gross premiums written $1,452,255 $428,644 $10,307 $139,010 ========== ======== ======= ======== 6 Underwriting Trenwick Group Ltd.'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 Group Ltd.'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 Group Ltd. 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 U.S. operations, which comprises fewer but significantly larger accounts, Trenwick Group Ltd. 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 Group Ltd. has established formal underwriting policy standards for both U.S. 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 Group Ltd. competes with numerous major international and domestic insurance and reinsurance companies in each of its business segments. These competitors, many of which have substantially greater financial and staff resources than Trenwick Group Ltd., 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 Group Ltd. 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. The financial security of insurers and reinsurers has emerged as a key issue throughout the past ten years. 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 Group Ltd. 7 Claims Administration Claims are managed by Trenwick Group Ltd.'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 Group Ltd.'s claim staff uses their own judgment as well as advice from lawyers and loss adjusters where appropriate. Trenwick Group Ltd. has a separate environmental claims unit to evaluate the complex toxic tort and latent injury claims resident in one of its U.S. insurance subsidiaries. Unpaid Claims and Claims Expenses General Insurers and reinsurers establish claims and claims expense liabilities representing estimates of future amounts needed to pay claims and related expenses with respect to insured events which have occurred. Claims and claims expense liabilities have two components: case liabilities, which are liabilities for reported claims, and incurred but not reported, or IBNR liabilities, which are liabilities 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 Group Ltd. first establishes its case liabilities for reported claims when it receives notice of the claim. It is Trenwick Group Ltd.'s general policy to establish liabilities for reported claims in an amount equal to the greater of the liability recommended by the ceding company or the claim as estimated by its claims personnel. Trenwick Group Ltd. 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 additional facts become known, it may become necessary to refine and adjust upward or downward the estimated liabilities on a claim, and even then the ultimate net liabilities may be less than or greater than the revised estimates. Actuarial Methods Trenwick Group Ltd. utilizes several actuarial evaluation methods including 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 Group Ltd.'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 Group Ltd. 8 Trenwick Group Ltd. provides capital to its Lloyd's corporate members, which support the underwriting capacity of the Lloyd's syndicates managed by Chartwell Managing Agents Limited. Claim liabilities for this business are established using methods similar to those used by Trenwick Group for its operating insurance company subsidiaries. Chartwell Managing Agents Limited has engaged Bacon & Woodrow Deloitte, an independent actuarial consulting firm, to review the claim liabilities and prepare an actuarial opinion for each of its syndicates, including the actuarial opinion required by Lloyd's solvency regulations. The Bacon & Woodrow Deloitte opinions, which are prepared solely for the use of Lloyd's regulators and are only to be relied upon by Chartwell Managing Agents Limited, assist its syndicates in establishing appropriate liability estimates for both the reinsurance to close and the open years of account. In the liability setting process, Trenwick Group Ltd. includes provisions for inflation and "social inflation" if appropriate, as losses are generally not determined until some time in the future. Trenwick Group Ltd. continually monitors legislative activity and evaluates the potential effect of any legislative changes on its reserve liabilities. Trenwick Group Ltd.'s claim liabilities are carried at management's best estimate of the ultimate expected claim liabilities and claim adjustment expense, generally without any discount to reflect the time value of money in accordance with both statutory accounting practices and U.S. GAAP. Certain workers' compensation indemnity claim liabilities are discounted using an interest rate of 3.5%. Trenwick Group Ltd.'s actuarial department regularly performs claim liability analyses for its operating insurance company subsidiaries. Loss Development Analysis The following table presents the development of Trenwick Group Ltd.'s net liabilities for unpaid claims and claims expenses for 1994 (the date of inception of LaSalle Re Limited) through 2001. The top line of the table shows the net liabilities for 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 Group Ltd. 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 liabilities for 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, 1994 through 2001. 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 1994 through 2001 represents the aggregate change in the initial gross estimates over all subsequent calendar years. 9 DEVELOPMENT OF UNPAID CLAIMS AND CLAIMS EXPENSES (monetary amounts expressed in thousands of United States dollars) 2001 2000 1999 1998 ---------------------------------------------------------- Net unpaid claims and claims expenses, beginning of year $ 1,621,970 $ 1,375,156 $ 172,576 $ 100,534 Cumulative amount of net liability paid as of: One year later 473,703 77,618 57,224 Two years later 130,425 86,267 Three years later 107,340 Four years later Five years later Six years later Seven years later Net liability re-estimated as of: One year later 1,501,406 193,552 144,490 Two years later 192,359 141,733 Three years later 141,561 Four years later Five years later Six years later Seven years later Net cumulative deficiency (126,250) (20,976) (41,199) Percentage (9.2)% (12.2)% (41.0)% Gross liability, end of year 2,375,124 190,352 100,534 Reinsurance recoverable 999,968 17,776 0 Net liability, end of year 1,375,156 172,576 100,534 Gross re-estimated liability-latest 2,521,602 209,551 141,733 Re-estimated recoverable-latest 1,020,196 15,999 0 Net re-estimated liability-latest 1,501,406 193,552 141,733 Gross cumulative deficiency (146,478) (19,199) (41,199) 1997 1996 1995 1994 ----------------------------------------------------- Net unpaid claims and claims expenses, beginning of year $ 45,186 $ 45,981 $ 60,887 $ 31,089 Cumulative amount of net liability paid as of: One year later 34,805 21,171 54,147 19,030 Two years later 52,184 39,432 65,618 30,825 Three years later 68,343 44,519 72,269 34,119 Four years later 69,517 47,100 72,923 37,350 Five years later 48,776 73,734 37,383 Six years later 74,196 38,022 Seven years later 38,230 Net liability re-estimated as of: One year later 81,811 43,053 76,344 41,967 Two years later 88,458 54,184 72,537 41,757 Three years later 88,259 56,814 80,131 38,899 Four years later 87,476 56,411 79,111 41,012 Five years later 55,600 78,858 39,955 Six years later 78,105 40,359 Seven years later 40,222 Net cumulative deficiency (43,073) (10,430) (17,971) (9,270) Percentage (95.3)% (22.7)% (29.5)% (29.8)% Gross liability, end of year 45,186 45,981 60,887 31,089 Reinsurance recoverable 0 0 0 0 Net liability, end of year 45,186 45,981 60,887 31,089 Gross re-estimated liability-latest 88,259 56,411 78,858 40,359 Re-estimated recoverable-latest 0 0 0 0 Net re-estimated liability-latest 88,259 56,411 78,858 40,359 Gross cumulative deficiency (43,073) (10,430) (17,971) (9,270) 10 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 1999 to be $150,000 was first reserved in 1994 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 1994-2000 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, 1999 have developed unfavorably due to LaSalle Re Holdings Limited's unfavorable development for catastrophe losses relating to the European storms in accident year 1999. Net unpaid claims and claims expenses at December 31, 2001 includes reinsurance recoverable of $92.0 million under the adverse development cover purchased by Chartwell Re Corporation in connection with its acquisition by Trenwick Group Inc. For further discussion of unpaid claims and claims expenses, see Note 4 of Notes to the Consolidated Financial Statements of Trenwick Group Ltd. Management believes that Trenwick Group Ltd.'s claim and claim expense liabilities are adequate. However, the process of estimating claims and claim expense liabilities 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 Group Ltd.'s ultimate liability will not vary significantly from amounts reserved. The inherent uncertainties of estimating such liabilities 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. Claims liabilities 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 Group Ltd.'s exposure to such latent losses is lessened because of its relatively recent entry into the reinsurance business (other than one of the U.S. insurance subsidiaries), 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 the contingent interest notes, the payment of which is subject to reduction in the event of such adverse reserve development related to a U.S. insurance subsidiary's business. Reserves for Trenwick Group Ltd.'s participation in Lloyd's syndicates through its Lloyd's corporate members are included in the 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 1999, 2000 and 2001. Consequently, there can be no assurance as to the adequacy of reserves and the risk of future developments, both favorable and unfavorable, exists. Trenwick Group Ltd.'s unpaid claims and claims expense liability at December 31, 2001 and 2000 includes an estimate of Trenwick Group Ltd.'s ultimate liability for asbestos and environmental claims of $91.0 million and $70.5 million, respectively, comprising gross liabilities for unpaid claims and claims expenses of $118.7 million and $99.5 million, respectively, net of reinsurance recoverable on unpaid claims and claims expenses of $27.6 million and $28.9 million. The balance sheet prior to the Trenwick/LaSalle business combination did not include liabilities for asbestos and environmental reserves, as LaSalle Re Holdings Limited's business did not provide for such coverage. Under Trenwick Group Ltd.'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. 11 Contingent Interest Notes Upon consummation of the acquisition of Chartwell Re Corporation in 1999, Trenwick Group Inc. became the successor obligor under Chartwell Re Corporation's Contingent Interest Notes due June 30, 2006. Effective September 27, 2000, Trenwick America Corporation assumed Trenwick Group Inc.'s obligations under the contingent interest notes in connection with the Trenwick/LaSalle business combination. The contingent interest notes were issued immediately prior to Chartwell Re Corporation's acquisition of Piedmont Management Company Inc. to protect Chartwell Re Corporation against increases in unpaid claims and claims expenses and long-tail casualty exposures at the company being acquired. The contingent interest notes were issued in an aggregate principal amount of $1 million, which accrues interest at a rate of 8% per annum, compounded annually. The interest is not payable until the maturity or earlier redemption of the contingent interest notes. In addition, the contingent interest notes entitle their holders to receive at maturity, in proportion to the principal amount of the contingent interest notes held by them, an aggregate of from $1 million up to $55 million in contingent interest. The amount of contingent interest payable under the contingent interest notes is dependent upon the level of loss and loss adjustment expense reserves related to business written by Trenwick Group Ltd.'s subsidiary, The Insurance Corporation of New York, prior to 1996. Settlement of the contingent interest notes may be made by payment of cash or, under certain specified conditions, by delivery of Trenwick Group Ltd.'s common shares. In order for the contingent interest notes to be settled in common shares of Trenwick Group Ltd., Trenwick Group Ltd.'s common shares must be registered under the Securities Act of 1933 and listed on a national securities exchange or the NASDAQ National Market. For purposes of any settlement of the contingent interest notes in Trenwick Group Ltd.'s common shares, the value ascribed to each common share shall be 85% of the average of the closing sales prices of the common shares for the 20 trading days immediately preceding the fifth trading day prior to the settlement date. Catastrophe Equity Put On September 27, 2000, Trenwick Group Ltd. assumed the benefits and obligations of LaSalle Re Holdings Limited under a catastrophe equity put option program and as of January 1, 2001 and January 25, 2002 amended and restated the catastrophe equity put. As amended, the catastrophe equity put enables Trenwick Group Ltd. to raise up to $55 million of equity through the issue of convertible preferred shares to the option writer in the event there is a qualifying catastrophic event or events occurring prior to January 1, 2002. The preferred shares can be redeemed by Trenwick Group Ltd. at any time following their issue. In addition, the option writer can convert its preferred shares into common shares of Trenwick Group Ltd. at any time after they have been outstanding for five years or upon a change in control of Trenwick Group Ltd. or a decline in Trenwick Group Ltd.'s net worth below a specified level. Conversion is at the greater of the book value of Trenwick Group Ltd. at the date of conversion or the market value of the common shares based on the 30-day trading average prior to conversion. Trenwick Group Ltd. was obligated to pay an annual net option premium for the catastrophe equity put. As a result of the terrorist attacks of September 11, 2001, Trenwick Group Ltd. has incurred $120 million in catastrophe losses as defined under the option agreement. If these losses develop to $140 million prior to March 11, 2003, Trenwick Group Ltd. will be entitled to exercise the catastrophe equity put and raise $55 million of equity, subject to regulatory approvals. Reinsurance and Retrocessional Agreements Trenwick Group Ltd. enters into reinsurance and retrocessional agreements to reduce its net liability on individual risks, protect against catastrophic losses and maintain acceptable loss ratios. In 2001, LaSalle Re Limited has purchased three excess of loss programs which provide coverage of $20 million in excess of the first $30 million of losses per occurrence, $5 million in excess of the first $50 million of losses per occurrence and $25 million in excess of the first $75 million of losses per occurrence. 12 LaSalle Re Limited had purchased an excess of loss program which provides coverage of $75.0 million in excess of the first $75.0 million of losses per occurrence for a first loss event and $60.0 million excess of $75.0 million per occurrence on the second loss event and $52.5 million excess of $125.0 million per occurrence on the third loss event over a three-year period ended December 31, 2001 subject to a maximum aggregate recovery of $187.5 million. This contract was cancelled effective December 31, 2000. The coverage was provided by a company that held a claims paying ability rating of AA from Standard and Poor's. As part of its overall protection against catastrophe losses, LaSalle Re Limited has also purchased the catastrophe equity put option discussed above. LaSalle Re Limited has also purchased other non-proportional excess of loss protections, which provide for the recovery of losses from reinsurers in excess of certain retentions that are related to the magnitude of market losses. LaSalle Re Limited reviews the claims paying ability of each reinsurer for adequacy before each cover is placed. Trenwick America Reinsurance Corporation has various retrocessional facilities, all of which are on a treaty basis. These retrocessional facilities include three treaties 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 Reinsurance Corporation's maximum retention generally does not exceed $4.3 million per occurrence on property catastrophe business. From 1989 to 1999, Trenwick America Reinsurance Corporation has purchased aggregate excess of loss ratio treaties from several reinsurers. These facilities provided Trenwick America Reinsurance Corporation with a layer of protection against adverse results from its domestic casualty business in excess of specified loss ratios on an accident year basis. Trenwick America Reinsurance Corporation did not purchase an aggregate excess of loss ratio treaty after 1999. Trenwick International Limited, 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 Limited increased its retention of business by reducing the amount of reinsurance it buys, principally proportional reinsurance treaties with its former parent. Chartwell Managing Agents Limited, 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 Inc. purchases reinsurance specifically tailored to each of the specialty programs underwritten by its insurance subsidiaries. In connection with the acquisition of Chartwell Re Corporation by Trenwick Group Ltd., Chartwell Re Corporation's insurance company subsidiaries purchased an aggregate excess of loss reinsurance agreement providing up to $100 million in coverage against unanticipated increases in Chartwell Re Corporation's reserves for business written on or before October 27, 1999, the date of completion of the acquisition of Chartwell Re Corporation. Within the $100 million maximum, the protection was limited to $100 million for increased reserves attributable to Chartwell Re Corporation'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 Scandinavian Re, and their obligations have been secured by a trust account. The premium paid for this aggregate excess of loss reinsurance agreement was $56 million, and the $100 million coverage limit was exhausted during the 2000 year. 13 Trenwick Group Ltd. remains liable with respect to insurance and reinsurance ceded in the event that the reinsurer 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 Group Ltd. 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 Group Ltd. Business may not be conducted with reinsurers or retrocessionaires who are not currently approved by the security committees. Of Trenwick Group Ltd.'s $1.4 billion in reinsurance recoverable balances, $719 million relates to Chartwell Managing Agents Limited's insurance underwriting operations at Lloyd's, which rely heavily on reinsurance in its insurance underwriting, particularly for the aviation business it underwrites. Approximately $200 million of this $719 million comes directly from the aviation losses from the September 11th terrorist attacks. Of LaSalle Re Limited's $57 million in reinsurance recoverable balances, all but $2 million also relate to the September 11th losses. Canterbury Financial Group Inc., the U.S. program insurer, has $166 million in reinsurance recoverable balances. Canterbury also relies on reinsurance in its underwriting, while maintaining an average retention of 34% in the business it underwrites. Finally, $180 million of the total relates to finite reinsurance coverage and $289 million relates to operational reinsurance for Trenwick America Reinsurance Corporation ($198 million) and Trenwick International Limited ($91 million). The finite reinsurance balances of $180 million, net are due from five reinsurers and are collateralized, both with funds held and letters of credit. The operational reinsurance balances of $1.2 billion are for paid losses ($156 million, or 13%) and unpaid losses, including both incurred, reported losses and incurred, but not reported losses ($1,075 million, or 87%). Allowances for uncollectible balances of $55 million have been recorded, including $23 million on paid losses (13% of the paid losses) and $32 million on unpaid losses (3% of the unpaid losses). In the ordinary course of business, losses are paid to insureds prior to any recovery on reinsurance. Except for allowances provided against recoverable balances for paid losses, no losses are expected on collection of these balances. The operational reinsurance balances are recoverable from a broadly diversified group of companies with 61 reinsurers comprising 80% of the total of $1.2 billion. Of these 61 reinsurers, 88% are rated A- or better by Standard & Poor's, or A.M. Best if no S&P rating is available. 14 Tables that set forth the distribution of Trenwick Group Ltd.'s reinsurance recoverable balances, net, by source, type and credit quality rating follow: Total Finite Operational ---------- -------- ----------- Worldwide property catastrophe reinsurance $ 57,179 $ -- $ 57,179 U.S. treaty reinsurance 395,062 180,058 215,004 International specialty insurance and reinsurance 94,399 -- 94,399 Lloyd's syndicates 753,011 -- 753,011 U.S. specialty program insurance 166,398 -- 166,398 ---------- -------- ---------- Total before allowance for uncollectible balances 1,466,049 180,058 1,285,991 Allowance for uncollectible balances 54,580 -- 54,580 ---------- -------- ---------- Total $1,411,469 $180,058 $1,231,411 ========== ======== ========== Total Paid Unpaid Operational Losses Losses ----------- --------- ---------- Worldwide property catastrophe reinsurance $ 57,179 $ -- $ 57,179 U.S. treaty reinsurance 215,004 60,029 154,975 International specialty insurance and reinsurance 94,399 43,505 50,894 Lloyd's syndicates 753,011 53,903 699,108 U.S. specialty program insurance 166,398 21,833 144,565 ---------- -------- ---------- Total before allowance for uncollectible balances 1,285,991 179,270 1,106,721 Allowance for uncollectible balances 54,580 22,896 31,684 ---------- -------- ---------- Total $1,231,411 $156,374 $1,075,037 ========== ======== ========== % of 61 Number Total Largest ------------ ------------- ----------- Collateralized or AAA 13 $ 214,898 20.8% AA+ to AA- 11 190,684 18.4% A++ to A- 24 485,876 47.0% -- ---------- ----------- Total collateralized or A- or better 48 891,458 86.2% BBB to BBB- 2 31,372 3.1% Not rated 10 96,653 9.3% In rehabilitation 1 14,531 1.4% -- ---------- ----------- Total - 61 largest 61 1,034,014 100% == ========== =========== All others 251,977 ------------- Totals before allowance for uncollectible balances 1,285,991 Allowance for uncollectible balances 54,580 ------------- Total $1,231,411 ============= Investments The Investment Committee of Trenwick Group Ltd.'s Board of Directors oversees investments and sets procedures and guidelines for investment strategy. Trenwick Group Ltd.'s internal staff manage these investments and utilize the services of investment advisers, using an investment strategy which focuses on capital preservation and income predictability. This strategy also requires that the risks associated with these objectives are properly managed. Accordingly, Trenwick Group Ltd. emphasizes investment grade debt investments. At year end 2001, 74% of Trenwick Group Ltd.'s investments in debt securities were rated Aa or better. Trenwick Group Ltd.'s investment strategy permits an allocation for equity securities. At year end 2001, 1% of Trenwick Group Ltd.'s total investments and cash were invested in common and preferred equities. The primary risk associated with these securities is the exposure to daily market fluctuations. 15 The investments of each of Trenwick Group Ltd.'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 Group Ltd. invests in three types of structured securities: collateralized mortgage obligations ("CMOs"), mortgage-backed securities not backed by U.S. government agencies ("Non-agency MBS") and asset-backed securities ("ABS"), each accounting for 2.9%, 6.9% and 8.8%, respectively, of Trenwick Group Ltd.'s debt security investments at year end 2001. 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 is therefore higher than expected prepayments, or decelerated, because of higher interest rates and is 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 that is contingent on the structure of each security and its underlying collateral. The asset-backed securities owned by Trenwick Group Ltd. 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. Trenwick Group Ltd. also invests in agency pass-through securities that account for 15.5% of Trenwick Group Ltd.'s portfolio at December 31, 2001. As with CMOs, these securities are subject to prepayment risk. Of the structured securities and agency pass-through securities held by Trenwick Group Ltd. at December 31, 2001, 99.0% have a rating of A or better from various nationally recognized statistical rating organizations. Trenwick Group Ltd. holds debt securities and cash in a number of currencies. At year end 2001, approximately 79% and 16%, respectively, of Trenwick Group Ltd.'s debt securities and cash were held in U.S. dollars and U.K. sterling, and the remainder in eleven other currencies. 16 The tables below set forth the distribution of Trenwick Group Ltd.'s debt securities at year end 2001 by type, average maturity and quality rating.

Quarterly ratings for these other securities are as assigned by Fitch Investors Services, Standard and Poor's or Duff and Phelps. Ratings are generally assigned upon the issuance of the securities, subject to revision on the basis of majority evaluations certificates of deposit of $140 with a Moody's rating of "P-1" have been included with "Aaa" securities. Unrated securities are in default and have been written-down from their original cost basis. Regulation Trenwick Group Ltd. 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, Bermuda 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 Group Ltd.'s financial integrity and solvency in its business transactions and operations. Many of the insurance statutes and regulations applicable to Trenwick Group Ltd.'s subsidiaries relate to reporting and enable regulators to closely monitor Trenwick Group Ltd.'s performance. Typical required reports include information concerning Trenwick Group Ltd.'s capital structure, ownership, financial condition, and general business operations. United States Trenwick Group Ltd.'s U.S. operations are subject to extensive regulation under statutes that delegate regulatory, supervisory and administrative powers to state insurance commissioners. The extent of regulation varies from state to state, but generally has its source in statutes that delegate regulatory, supervisory and administrative authority to a department of insurance in each state. Among other things, state insurance commissioners regulate insurer solvency standards, insurer licensing, authorized investments, premium rates, restrictions on the size of risks that may be insured under a single policy, loss and expense reserves and provisions for unearned premiums, deposits of securities for the benefit of policyholders, policy form approval, and market conduct regulation, including the use of credit information in underwriting and other underwriting and claims practices. State insurance departments also conduct periodic examinations of the affairs of insurance companies and require the filing of annual and other reports relating to the financial condition of companies and other matters. In general, regulated insurers must file all rates for directly underwritten insurance with the insurance department of each state in which they operate on an admitted basis; however, reinsurance generally is not subject to rate regulation. Trenwick Group Ltd.'s U.S. insurance subsidiaries are subject to guaranty fund laws which can result in assessments, up to prescribed limits, for losses incurred by policyholders as a result of the impairment or insolvency of unaffiliated insurance companies. Typically, an insurance company is subject to the guaranty fund laws of the states in which it conducts insurance business; however, Trenwick Group Ltd.'s U.S. insurance subsidiaries that conduct business on a surplus lines basis in a particular state are generally exempt from that state's guaranty fund laws. Trenwick Group Ltd. does not expect the amount of any such guaranty fund assessments to be paid by Trenwick Group Ltd., if any, in 2002 to be material. Bermuda LaSalle Re Limited and LaSalle Re Corporate Capital Ltd. are regulated by the Bermuda Insurance Act 1978, which provides that no person shall carry on an insurance business in or from within Bermuda unless registered as an insurer under the Insurance Act by the Minister of Finance. Under the Insurance Act, insurance business includes reinsurance business. The Minister of Finance, in deciding whether to grant registration, has broad discretion to act as he thinks fit in the public interest. The Minister of Finance is required by the Insurance Act to determine whether the applicant is a fit and proper body to be engaged in the insurance business and, in 18 particular, whether it has, or has available to it, adequate knowledge and expertise. The registration of an applicant as an insurer is subject to its complying with the terms of its registration and such other conditions as the Minister of Finance may impose at any time. The Insurance Act distinguishes between insurers carrying on long-term business and insurers carrying on general business. There are four classifications of insurers carrying on general business, with Class 4 insurers subject to the strictest regulation. LaSalle Re Limited is registered as a Class 4 insurer in Bermuda and is regulated as such under the Insurance Act. The Insurance Act imposes on Bermuda insurance companies solvency, and liquidity standards and auditing and reporting requirements and grants to the Minister of Finance powers to supervise, investigate and intervene in the affairs of insurance companies. Although LaSalle Re Corporate Capital Ltd. is governed by the Insurance Act, it is exempted from complying with most of the filings required to be made by insurance companies by section 57 of the Insurance Act. United Kingdom Trenwick International Limited is subject to the regulatory authority of the United Kingdom Financial Services Authority. Both Chartwell Managing Agents Limited and Trenwick Group Ltd.'s dedicated Lloyd's underwriting entities, as a Lloyd's managing 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. 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. In 2000, the Financial Services and Markets Bill established the Financial Services Authority as a single regulator to supervise securities, banking and insurance business, including Lloyd's. In 2001, the Financial Services Authority gained wider authorization and intervention powers in relation to Lloyd's as part of the implementation of the Financial Services and Markets Act. NAIC The National Association of Insurance Commissioners, or NAIC, is an organization which assists state insurance supervisory officials in the United States to achieve 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 Group Ltd. is unable to predict what effect, if any, these developments may have on its operations and financial condition. In March 1998, the NAIC adopted the Codification of Statutory Accounting Principles, which is intended to standardize regulatory accounting and reporting for the insurance industry. 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 Reinsurance Corporation and Chartwell Insurance Company), and North Dakota (domicile of Dakota Specialty Insurance Company) adopted codification. New York (domicile of The Insurance Corporation of New York and ReCor 19 Insurance Company Inc.) adopted codification as well as certain prescribed accounting practices that differ from codification. The cumulative effect of adoption of the codification was an increase in aggregate statutory surplus of approximately $14 million, primarily due to the recording of net deferred income tax assets. Risk Based Capital The NAIC has adopted Risk-Based Capital, or 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 requires specific corrective action. The ratios of total adjusted capital to authorized control level RBC for each of Trenwick Group Ltd.'s United States insurance company subsidiaries exceeded all the RBC trigger points at December 31, 2001, 2000 and 1999. Holding Company Regulation Trenwick Group Ltd. is subject to regulation under the insurance holding company statutes of various states, including Connecticut, New York and North Dakota, the domicile states of its U.S. insurance companies. The insurance holding company 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 Group Ltd. 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. Dividends Because Trenwick Group Ltd.'s operations are conducted through its operating subsidiaries, it 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 Group Ltd.'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 Connecticut, the state of domicile of Trenwick America Reinsurance Corporation and Chartwell Insurance Company, 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 20 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. During 2001, the Connecticut Insurance Department approved Chartwell Insurance Company's extraordinary dividend of all of the common shares of The Insurance Corporation of New York to Canterbury Financial Group as part of a restructuring of Trenwick Group Ltd.'s U.S. subsidiaries. Under New York law, which is applicable to The Insurance Corporation of New York and ReCor Insurance Company Inc. 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 Group Ltd. to commit to preclude the acquired New York-domiciled insurers, The Insurance Corporation of New York and ReCor Insurance Company Inc., from paying any dividends for two years after the Trenwick/Chartwell merger without prior regulatory approval. The foregoing restriction expired on October 27, 2001. Under the applicable provisions of the insurance holding company laws of North Dakota, the state of domicile of Dakota Specialty Insurance Company, payment of dividends in any year without prior regulatory approval is limited to the greater of (i) 100% of statutory net income excluding realized capital gains for the previous year, or (ii) 10% of the insurer's policyholder's surplus, excluding surplus arising from unrealized appreciation on investments or other assets. 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. As of December 31, 2001, Trenwick Group Ltd.'s U.S. insurance subsidiaries could pay a dividend of $14.5 million without prior approval of the applicable insurance regulatory authority. During 2001, 2000 and 1999, Trenwick America Reinsurance Corporation paid cash dividends of $20.0 million, $19.3 million and $53.4 million, respectively. Chartwell Insurance Company paid cash dividends of $33.3 million in 2001 and $30.3 million in 1999. Chartwell Insurance Company did not pay any dividends in 2000. The Insurance Corporation of New York paid $10.0 million of cash dividends in 2001; it did not pay any dividends in 2000 or 1999. Trenwick Group Ltd.'s other U.S. insurance subsidiaries did not pay any dividends in 2001, 2000 or 1999. 21 Under The Companies Act 1981 of Bermuda, LaSalle Re Holdings Limited, LaSalle Re Limited and LaSalle Re Corporate Capital Ltd. are prohibited from declaring or paying a dividend or making a distribution out of contributed surplus and retained earnings if there are reasonable grounds for believing that (i) such company is, or would offer the payment be, unable to pay its liabilities as they come due or (ii) the realizable value of such company's assets would thereby be less than the aggregate of its liabilities and shareholders' equity. In addition, The Insurance Act 1978, as amended, the related regulations of Bermuda (the Insurance Act) would prohibit the payment of a dividend by LaSalle Re Limited or LaSalle Re Corporate Capital Ltd. if the payment of such dividend would result in either company no longer meeting its minimum solvency margin or minimum liquidity ratio. As a registered Class 4 insurer, LaSalle Re Limited is required to maintain a minimum solvency margin equal to the greatest of (1) $100 million, (2) 50% of its net premiums written (without deducting more than 25% of gross premiums written when computing net premiums written) and (3) 15% of its loss and other certain insurance reserves. The minimum liquidity ratio requires LaSalle Re Limited and LaSalle Re Corporate Capital Ltd. to maintain the value of their respective relevant assets at not less than 75% of the amount of their respective relevant liabilities. Under the applicable laws of the United Kingdom, Trenwick Group Ltd.'s U.K. subsidiaries may make shareholder distributions only from accumulated realized profits, net of accumulated realized losses. In addition, under the U.K. Insurance Companies Act, Trenwick International Limited 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 $27.0 million as of December 31, 2001. Trenwick International Limited 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 Limited is not permitted to make any distribution that would cause its assets to fall below any of Chartwell Managing Agents Limited's share capital, minimum net current asset margin or minimum net asset margin. As of December 31, 2001, the highest of the three tests required Chartwell Managing Agents Limited to maintain approximately $1.0 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 Group Ltd.'s United States insurance 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 Group Ltd. 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 Limited. Likewise, Lloyd's regulations govern the types and amounts of investments that are permissible for Chartwell Managing Agents Limited 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 Group Ltd. believes that it is in compliance with all material applicable investment laws. U.S. Financial Services Reform In 1999, new U.S. federal legislation was passed which implemented fundamental changes in the regulation of the financial services industry in the United States. The new law permits mergers that combine commercial banks, insurers and securities firms under one holding company, a "financial holding company." Bank holding companies and other entities that qualify and elect to be treated as a financial holding company may engage in activities, and acquire companies engaged in activities that are "financial" in nature or "incidental" or 22 "complementary" to such financial activities. These financial activities include acting as principal, agent or broker in the underwriting and sale of life, property, casualty and other forms of insurance and annuities. Until the passage of this new legislation, the Bank Holding Company Act of 1956, as amended, had restricted banks from being affiliated with insurers. The ability of banks to affiliate with insurers may materially affect our U.S. subsidiaries' product lines by substantially increasing the number, size and financial strength of potential competitors. United States Taxation Under current Bermuda law, no income, withholding or capital gains taxes are imposed upon Trenwick Group Ltd. and its Bermuda subsidiaries. Trenwick Group Ltd. and its Bermuda subsidiaries have received an undertaking from the Minister of Finance in Bermuda that, in the event of any taxes being imposed, Trenwick Group Ltd. and its Bermuda subsidiaries will be exempt from taxation in Bermuda until March 2016. Trenwick Group Ltd.'s U.S. subsidiaries carry on business in, and are subject to taxation in the United States. Trenwick Group Ltd. and its Bermuda subsidiaries believe that they have operated and will continue to operate their business in a manner that will not cause its Bermuda subsidiaries to generate income treated as effectively connected with the conduct of a trade or business within the United States. On this basis, Trenwick Group Ltd. does not expect that its Bermuda subsidiaries will be required to pay U.S. corporate income taxes other than withholding taxes on certain investment income and premium excise taxes. If Trenwick Group Ltd.'s Bermuda subsidiaries were subject to U.S. income tax, there could be a material adverse effect on Trenwick Group Ltd.'s financial condition, results of operations or cash flows. Employees At December 31, 2001, Trenwick Group Ltd. employed a total of 29, 143 and 257 persons in its Bermuda, United States and other international operations, respectively. Trenwick Group Ltd. has no employees represented by a labor union and believes that its employee relations are good. Item 2. Properties Trenwick Group Ltd.'s corporate headquarters and LaSalle Re Limited's operations are located in approximately 10,000 square feet of leased office space in Hamilton, Bermuda. Trenwick Group Ltd.'s United States operations are located in approximately 46,000 total square feet of leased office space at Stamford, Connecticut. Trenwick International Limited and Chartwell Managing Agents Limited leases approximately 29,000 square feet of space in London, England and Trenwick International Limited also leases 875 square feet of office space in Paris, France. Management believes Trenwick Group Ltd.'s current office space is adequate for its needs. Item 3. Legal Proceedings Trenwick Group Ltd. is party to various legal proceedings generally arising in the normal course of its business. Trenwick Group Ltd. does not believe that the eventual outcome of any such proceeding will have a material effect on its financial condition or business. Trenwick Group Ltd.'s subsidiaries are regularly engaged in the investigation and the defense of claims arising out of the conduct of their business. Pursuant to Trenwick Group Ltd.'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 No matters were submitted to a vote of shareholders of Trenwick Group Ltd. during the fourth quarter of 2001. 23 PART II Item 5.
