Page 1 of 6 pages This amendment to the Annual Report on Form 10K of ProAssurance, Corp. (the "Registrant") for the year ended December 31, 2001 is filed to correct typographical errors in the table included under the caption "Analysis of Losses and Loss Adjustment Expense Reserve Development" in Item 1 of Part 1. The "Cumulative net paid as of: Eight years later" amount for 1993 was reported as $86,821; however, it should be $76,821. The "Re-estimated net liability as of: One year later" amount for 1995 was reported as $352,212; however, it should be $325,212. The "Net re-estimated liability - latest" for 1997 was reported as $313,202; however, it should be $323,202. The "Gross cumulative redundancy" for 1996 was reported as $538,720; however, it should be $238,720. The "Gross cumulative redundancy" for 1999 was reported as $38,064; however, it should be $48,097. The section in Part 1, Item 1 entitled "Loss Reserve Development Table" is restated in its entirety on the following pages. 2 LOSS RESERVE DEVELOPMENT TABLE The following table includes information regarding the development of the liability for unpaid losses and LAE of ProAssurance for the years ended December 31, 1991 through 2001. The table includes losses and LAE on both a direct and an assumed basis and is net of reinsurance recoverables: - the line entitled "Losses and LAE Reserves, undiscounted and net of reinsurance recoverables" reflects the amount recorded as the reserve for liability for unpaid losses and LAE in the consolidated balance sheet at the end of each year (the "Balance Sheet Reserves"); - the section entitled "Cumulative net paid, as of" reflects the cumulative amounts paid as of the end of each succeeding year with respect to the previously recorded Balance Sheet Reserves; - the section entitled "Re-estimated net liability as of" reflects the re-estimated amount of the liability previously recorded as Balance Sheet Reserves that includes the cumulative amounts paid and an estimate of additional liability based upon claims experience as of the end of each succeeding year (the "Net Re-estimated Liability"); - the line entitled "Net cumulative redundancy, (deficiency)" reflects the difference between the previously recorded Balance Sheet Reserve for each applicable year and the Net Re-estimated Liability relating thereto as of the end of the most recent fiscal year. The gross liability for losses and LAE before reinsurance, as reflected on the balance sheet and re-estimated in each of the years since 1993, and the reconciliation of the gross liability to amounts net of reinsurance are reflected below the table. Information presented in the following table is cumulative and, accordingly, each amount includes the effects of all changes in amounts for prior years. The table presents the development of ProAssurance's Balance Sheet Reserves; it does not present accident year or policy year development data. Conditions and trends that have affected the development of liabilities 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 information relating to subsidiaries other than MA-Alabama is limited to the property and casualty reserves from their respective dates of acquisition. ProAssurance does not discount its reserves. 3 ANALYSIS OF LOSSES AND LOSS ADJUSTMENT EXPENSE RESERVE DEVELOPMENT (IN THOUSANDS) December 31, -------------------------------------------------------------------------------------------------------------- 1991(a) 1992(a) 1993(a) 1994(a) 1995(a) 1996(a) 1997(a) 1998(a) 1999(a) 2000(a) 2001(b) -------- -------- -------- -------- -------- -------- -------- -------- -------- -------- ---------- Losses and LAE reserves, undiscounted and net of reinsurance recoverables $228,119 $252,739 $272,392 $295,541 $352,521 $440,040 $464,122 $480,741 $486,279 $493,457 $1,068,285 Cumulative net paid as of: One year later 19,560 19,752 21,296 24,102 27,532 48,390 67,383 89,864 133,832 143,892 Two years later 35,461 36,185 40,988 42,115 58,769 98,864 128,758 192,716 239,872 Three years later 46,417 52,550 53,186 58,793 80,061 136,992 194,139 257,913 Four years later 58,124 58,526 61,153 65,520 107,005 173,352 227,597 Five years later 62,573 63,325 66,419 76,291 120,592 191,974 Six years later 65,090 68,021 73,308 81,722 129,043 Seven years later 68,719 71,466 76,716 82,605 Eight years later 71,305 72,352 76,821 Nine years later 71,802 79,788 Ten years later 71,994 Re-estimated net liability as of: End of Year $228,119 $252,739 $272,392 $295,541 $352,521 $440,040 $464,122 $480,741 $486,279 $493,457 $1,068,285 One year later 217,558 241,655 251,445 268,154 325,212 393,363 416,814 427,095 463,779 507,275 Two years later 205,277 221,236 220,385 239,243 280,518 347,258 364,196 398,308 469,934 Three years later 185,349 190,744 194,213 200,311 237,280 294,675 333,530 400,333 Four years later 159,301 167,062 159,096 157,836 190,110 264,714 323,202 Five years later 139,570 136,996 126,379 122,570 173,148 259,195 Six years later 114,407 108,862 106,403 105,779 168,828 Seven years later 97,177 94,908 92,954 99,787 Eight years later 89,271 84,719 88,828 Nine years later 79,734 79,788 Ten years later 76,042 Net cumulative redundancy (deficiency) 152,077 172,951 183,564 195,754 183,693 180,845 140,920 80,408 16,345 (13,818) ======= ======= ======= ======= ======= ======= ======= ====== ====== ======= Original gross liability - end of year 311,394 355,735 432,937 548,732 614,720 660,631 665,786 659,659 Less: reinsurance recoverables (39,002) (60,194) (80,416) (108,692) (150,598) (179,890) (179,507) (166,202) ------- ------- ------- -------- -------- -------- -------- -------- Original net liability - end of year 272,392 295,541 352,521 440,040 464,122 480,741 486,279 493,457 ======= ======= ======= ======= ======= ======= ======= ======= Gross re-estimated liability - latest 98,152 130,718 197,555 310,012 424,519 542,396 617,689 651,359 Re-estimated reinsurance recoverables (9,324) (30,931) (28,727) (50,817) (101,317) (142,063) (147,755) (144,084) ------ ------- ------- ------- -------- -------- -------- ------- Net re-estimated liability - latest 88,828 99,787 168,828 259,195 323,202 400,333 469,934 507,275 ====== ====== ======= ======= ======= ======= ======= ======= Gross cumulative redundancy 213,242 225,017 235,382 238,720 190,201 118,235 48,097 8,300 ======= ======= ======= ======= ======= ======= ====== ===== (a) Reflects reserves of Medical Assurance excluding Professionals Group reserves, which were acquired on June 27, 2001. Accordingly, the gross and net reserve development (reserves recorded at the end of the year, as originally estimated, less reserves re-estimated as of subsequent years) relates only to the operations of Medical Assurance and does not include Professionals Group. (b) Reflects combined reserves of Medical Assurance and Professionals Group as December 31, 2001. 4 Medical professional liability loss experience is volatile and cyclical. Over the past twenty-five years, the industry has experienced several periods of increasing claim frequency and severity, followed by periods of relative stability. At other times, due to tort reform, favorable judicial decisions, favorable economic conditions or other unknown factors, claim frequency and/or severity have decreased. Malpractice claims generally require an extended period of time to resolve, and in many jurisdictions, the average life of a claim is five years or longer. The combination of changing conditions and the extended time required for claim resolution result in a loss cost estimation process that requires actuarial skill and good judgment, and such estimates require periodic revision. Management believes it is prudent to establish initial loss and loss expense reserves that are reasonable and are based on historical experience as well as on facts and circumstances known at the balance sheet date. To the extent that actual results deviate from expectations, reserve estimates are subsequently adjusted and ultimate paid losses and loss expenses are more or less than the original estimates. ProAssurance's loss and loss expense reserves developed favorably in many prior years for several reasons. First, ProAssurance utilizes a rigorous and disciplined approach to investigating, managing and defending claims. This philosophy, especially in Alabama, has generally produced results that are better than industry averages in terms of loss payments and the proportion of claims closed without indemnity payment. Second, ProAssurance's volume of business, while substantial, is not of a sufficient size to fully support the projection process, thus ProAssurance's data is supplemented with industry-based data. Ultimately, actual payments on these reserves have often been less than originally projected, creating redundancies. Third, reserves established in the late 1980's and early 1990's were strongly influenced by the dramatically increased frequency and severity experienced by ProAssurance, and the industry as a whole, during the mid-1980's. Some of these trends moderated, and in some cases, reversed, by the late 1980's or early 1990's. However, the ability to recognize the improved environment was delayed due to the extended time required for claims resolution. When these trends moderated, the reserves established during those periods proved to be redundant. Finally, ProAssurance believed that its overall loss experience would be worse than that which was anticipated by many of its competitors. As a result, ProAssurance prudently established accident year reserves, resulting in accident year loss ratios in excess of 100% of earned premium. In some instances, these loss ratios proved to be accurate, while in other cases, experience has been better than expected and redundancies have developed. The professional liability legal environment has deteriorated once again during the past several years. Beginning in 2000, ProAssurance recognized adverse trends in claim severity, causing increased estimates of certain loss liabilities. As a result, favorable development of prior year loss reserves slowed during 2000 and some amount of adverse development occurred during 2001. ProAssurance has addressed these trends through increased rates, stricter underwriting and modifications to claims-handling procedures. In each year, ProAssurance has utilized a consistent approach in establishing reserve levels. The actuarial methodologies utilized include incurred loss development, paid loss development and frequency-severity projections. These techniques are applied to the data and the resulting projections are evaluated by management to establish a best estimate of reserves. 5 SIGNATURES Pursuant to the requirements of Section 13 of 15(d) of the Securities Exchange Act of 1934, the Registrant has duly caused Amendment No. 1 to this report to be signed on its behalf by the undersigned, thereunto duly authorized, on this the 4th day of April 2002.
