BUSINESS. GENERAL Zenith National Insurance Corp. ("Zenith National"), a Delaware corporation incorporated in 1971, is a holding company engaged through its wholly-owned insurance subsidiaries, Zenith Insurance Company ("Zenith Insurance") CalFarm Insurance Company ("CalFarm") (through March 31, 1999, the date of its sale), ZNAT Insurance Company ("ZNAT Insurance") and Zenith Star Insurance Company ("Zenith Star") (collectively, the "P&C Operations"), in the property-casualty insurance business. Zenith National and its subsidiaries (collectively, "Zenith") also conducts Real Estate Operations through wholly-owned subsidiaries which develop land and construct private residences for sale in Las Vegas, Nevada. On April 1, 1998, Zenith Insurance acquired substantially all of the assets and certain liabilities of RISCORP, Inc. and certain of its subsidiaries (collectively, "RISCORP") related to RISCORP's workers' compensation business (the "RISCORP Acquisition"). Effective March 31, 1999, Zenith Insurance completed the sale of all of the issued and outstanding capital stock of CalFarm, for $273.0 million in cash to Nationwide Mutual Insurance Company. The 1999 edition of Best's Key Rating Guide ("Best's") assigns the P&C Operations ratings of A+ (superior). Moody's Investors Service ("Moody's") has assigned insurance financial strength ratings of Baa1 (adequate) to the P&C Operations. Standard & Poor's Corporation ("S&P") has assigned an insurer financial strength rating to the P&C Operations of A (strong). These Best's, Moody's and S&P ratings are based upon factors of concern to policyholders and insurance agents and are not directed toward the protection of investors. At December 31, 1999, Zenith had approximately 1,200 full-time employees. The principal executive offices of Zenith are located at 21255 Califa Street, Woodland Hills, California 91367-5021, telephone (818) 713-1000. GLOSSARY OF SELECTED INSURANCE TERMS The following terms when used herein have the following meanings: Assume To receive from a ceding company all or a portion of a risk in consideration of receipt of a premium. Cede To transfer to a reinsurer all or a portion of a risk in consideration of payment of a premium. Combined ratio The sum of underwriting expenses, net incurred losses, loss adjustment expenses and policyholders' dividends, expressed as a percentage of net premiums earned. The combined ratio is the key measure of underwriting profitability used in the property-casualty insurance business. Development The amount by which losses, measured subsequently by reference to payments and additional estimates, differ from those originally reported for a period. Development is favorable when losses ultimately settle for less than levels at which they were reserved or subsequent estimates indicate a basis for reserve decreases on open claims. Development is unfavorable when losses ultimately settle for more than levels at which they were reserved or subsequent estimates indicate a basis for reserve increases on open claims. 1 Excess of loss reinsurance A form of reinsurance in which the reinsurer pays all or a specified percentage of a loss caused by a particular occurrence or event in excess of a fixed amount and up to a stipulated limit. Incurred but not reported claims Claims relating to insured events that have occurred but have not yet been reported to the insurer or reinsurer. Loss adjustment expenses The expenses of investigating and settling claims, including legal and other fees, and general expenses of administering the claims adjustment process. Loss ratio Net losses incurred expressed as a percentage of net premiums earned. Net premiums earned The portion of net premiums written applicable to the expired period of policies. Participating policy A policy upon which dividends may be paid after expiration. Policyholders' surplus The amount remaining after all liabilities are subtracted from all admitted assets, as determined in accordance with statutory accounting practices. This amount is regarded as financial protection to policyholders in the event an insurance company suffers unexpected or catastrophic losses. Reinsurance A transaction in which an original insurer, or cedant, remits a portion of the premium to a reinsurer, or assuming company, as payment for the reinsurer's assumption of a portion of the risk. Reserves or loss reserves The balance sheet liability representing estimates of amounts needed to pay reported and unreported claims and related loss adjustment expenses. Retrocession A reinsurance of reinsurance assumed. Retrospectively-rated policy A policy containing a provision for determining the insurance premium for a specified policy period on the basis of the loss experience for the same period. Statutory accounting practices Accounting practices prescribed or permitted by the states' departments of insurance. In general, statutory accounting practices address policyholder protection and solvency and are more conservative in presentation of earnings, surplus and assets than generally accepted accounting principles. Treaty A contract of reinsurance. Underwriting The process whereby an insurer reviews applications submitted for insurance coverage and determines whether it will accept all or part, and at what premium, of the coverage being requested. Underwriting expenses The aggregate of policy acquisition costs and the portion of administrative, general and other expenses attributable to the underwriting process as they are accrued and expensed. DESCRIPTION OF THE BUSINESS Zenith classifies its business into six segments: Workers' Compensation, Other Property-Casualty (through March 31, 1999, the date of sale of CalFarm), Reinsurance, Real Estate Operations, Investment and Parent. Segments are designated based on the types of products and 2 services provided and based on the risks associated with the products and services. Workers' Compensation represents insurance coverage for the statutorily prescribed benefits that employers are required to pay to their employees injured in the course of employment. Prior to its sale, CalFarm operated Zenith's Other Property-Casualty business, which represented multiple product line direct insurance other than workers' compensation. Reinsurance represents the book of assumed reinsurance of principally property losses from catastrophes and the reinsurance of large property risks. Results of such operations for the three years ended December 31, 1999 are set forth in the tables in the section Management's Discussion and Analysis of Consolidated Financial Condition and Results of Operations--"Overview" on page 26 of Zenith's 1999 Annual Report to Stockholders, which table is hereby incorporated by reference. The Investment segment represents investment income and realized gains on investments, primarily from debt securities. Real Estate Operations are conducted through wholly-owned subsidiaries that develop land and construct private residences for sale in Las Vegas, Nevada. Parent represents the holding company operations of Zenith National which owns, directly or indirectly, all of the capital stock of the property-casualty insurance and non-insurance companies. Zenith's business segments are described in Notes to Consolidated Financial Statements -- Note 18 -- "Segment Information" on pages 63-64 of Zenith's 1999 Annual Report to Stockholders, which note is hereby incorporated by reference. WORKERS' COMPENSATION Workers' Compensation insurance provides coverage for the statutorily prescribed benefits that employers are required to pay to their employees injured in the course of employment. The standard workers' compensation policy issued by the P&C Operations provides payments for, among other things, temporary or permanent disability benefits, death benefits, medical and hospital expenses and expenses of vocational rehabilitation. The benefits payable and the duration of such benefits are set by statute, and vary by state and with the nature and severity of the injury or disease and the wages, occupation and age of the employee. In 1998, Zenith expanded its presence in Florida and other states through the RISCORP Acquisition (see page 5 for a discussion of the RISCORP Acquisition). During 1999, the P&C Operations wrote workers' compensation insurance in 40 states. Net premiums earned in 1999 by state are set forth in the table below: (DOLLARS IN THOUSANDS) 1999 % - ---------------------- --------- -------- California................................................ $107,929 38.7% Florida................................................... 92,562 33.2 Texas..................................................... 17,560 6.3 North Carolina............................................ 16,301 5.8 Alabama................................................... 7,687 2.8 Arkansas.................................................. 6,731 2.4 Pennsylvania.............................................. 5,639 2.0 Other..................................................... 24,445 8.8 -------- ----- $278,854 100.0% ======== ===== Excluding the impact of the RISCORP-Related Adjustment (see page 5), Zenith's low, five-year Workers' Compensation loss ratio was 59.8% through 1999, which was attributed to Zenith's pricing and underwriting strategies managed care efforts, return-to-work strategies, and safety and health, anti-fraud and litigation efforts. During the past 10 years, Zenith's Workers' Compensation combined ratio was 107.2% excluding the RISCORP-Related Adjustment. Results of operations of Zenith's Workers' Compensation Operations are being adversely impacted by severe competition and inadequate pricing. Industry results in California are at historic 3 unprofitable levels and national results are deteriorating. Except in its Southeast Operations, which principally consists of the former operations of RISCORP, Workers' Compensation premium revenues are declining as Zenith endeavors to maintain rate adequacy. In Florida, minimum premium rates for workers' compensation insurance are established by the Florida Insurance Commissioner. Minimum rates increased by 1.6% in 1999 and decreased 3.2% and 11.3% in 1998 and 1997, respectively. Since rates were deregulated in California in 1995, insurance companies file and use their own, actuarially determined rates for workers' compensation insurance in California. Companies must file such rates with the California Department of Insurance, but the use of scheduled rating credits allows companies considerable flexibility in determining the amount of premium to be charged to a policyholder or potential policyholder, resulting in intense competition. Results of January 2000 renewals and new business applications in California were favorable with Zenith renewing a substantial percentage of its maturing policies at higher rates and writing some new business. In November of 1999, the California Insurance Commissioner adopted an average 18.4% increase in the pure premium advisory rates recommended by the Workers' Compensation Insurance Rating Bureau of California -- a preliminary indication of possible changes in the California workers' compensation market. In any event, in 2000 Zenith has raised its rates by an appropriate amount, together with other actions, with a goal to improve its profitability. Generally, premiums for workers' compensation insurance policies are a function of the applicable premium rate, which includes the insured employer's experience modification factor (where applicable) and the amount of the insured employer's payroll. Payrolls may be affected significantly by changes in employment and wage levels. A deposit premium is paid at the beginning of the policy period, periodic installments are paid during the policy period and the final amount of the premium is generally determined as of the end of the policy period after the policyholder's payroll records are audited. As part of the RISCORP Acquisition, Zenith Insurance assumed approximately $32.0 million of premium in-force on retrospectively-rated policies. Retrospective rating also allows the policyholder to share in the benefits of favorable loss experience although a certain amount of less-than-favorable experience will result in additional premiums being billed to the policyholder. On April 1, 1998, Zenith Insurance completed the RISCORP Acquisition. The total purchase price for such acquired assets and liabilities was determined by a three-step process in which RISCORP and its external accounting and actuarial consultants and Zenith Insurance and its external accounting and actuarial consultants made and presented their estimates of the generally accepted accounting principles ("GAAP") basis values of the assets and liabilities acquired by Zenith Insurance to an independent third-party, acting as a Neutral Auditor and Neutral Actuary. Such estimates varied considerably, particularly with respect to the value of premiums receivable and the liability for unpaid losses and loss adjustment expenses. On March 19, 1999, the Neutral Auditor and Neutral Actuary issued its report determining the disputes between the parties. That report indicated that the value of the assets transferred to Zenith Insurance exceeded the value of the liabilities assumed by Zenith Insurance by $92.3 million. In October of 1999, Zenith Insurance completed a review of the liabilities for unpaid losses and loss adjustment expenses in its Southeast Operations, which principally consists of the operations acquired from RISCORP. The review was conducted with assistance from independent actuarial consultants. As a result of the review, Zenith Insurance recorded, in the third quarter of 1999, an increase of $46.0 million before tax in the estimated net liabilities for unpaid losses and loss adjustment expenses acquired from RISCORP. The increase results primarily from the adjustments to reserves for the years 1994 through 1997. Certain related receivables, principally contingent commissions receivable under reinsurance contracts assumed from RISCORP, were reduced by $19.0 million as a result of such increase in net liabilities. Such adjustments to the values of the net assets acquired and liabilities assumed were offset by (a) the net benefit of $34.0 million associated 4 with reinsurance protection for adverse loss development and (b) $6.0 million recovered from RISCORP to settle certain litigation (see Item 3. Legal Proceedings on page 14). The adjustments associated with the increase in the liabilities for unpaid loss and loss adjustment expenses acquired from RISCORP, net of the benefit of reinsurance protection and the effect of the Settlement Agreement, in the aggregate (collectively, the "RISCORP-Related Adjustment"), reduced income by $32.5 million after tax, or $1.89 per share in the third quarter of 1999. Deferred reinsurance benefits will be recognized over approximately the next four years and net income is expected to increase by $15.0 million. OTHER PROPERTY-CASUALTY Zenith, through CalFarm, offered a comprehensive line of property-casualty insurance for individual and commercial customers, including automobile, farmowners, commercial coverages, group health and homeowners coverage, primarily in the rural and suburban areas of California, through March 31, 1999, the effective date of the sale of CalFarm to Nationwide Mutual Insurance Company. Automobile insurance included coverage for automobile bodily injury, property damage and physical damage. Automobile bodily injury and property damage insurance provided coverage for third party liability, bodily injury and property damage arising from the ownership, maintenance or use of an automobile. Automobile physical damage coverage insured against physical loss of the insured's own vehicle. Farmowners and homeowners insurance included coverage for direct physical damage to real and personal property, loss of personal property by theft and legal liability for injury to others and damage to property of others. Commercial multiple peril provided coverage for businesses against property damage and general liability. Health insurance premiums were written under a program sponsored by the California Farm Bureau Federation which included a preferred provider organization plan and a Medicare supplement product. For the 14 years since CalFarm was acquired by Zenith, the average combined ratio of the Other Property-Casualty Operations was 100.1%. Effective March 31, 1999, Zenith Insurance completed the sale of all of the issued and outstanding capital stock of CalFarm for $273.0 million in cash to Nationwide Mutual Insurance Company. The gain on the sale after tax was $104.3 million. After accounting for applicable taxes, expenses and certain intercompany transactions, the net proceeds from the sale that were available to Zenith Insurance for investment were $211.0 million, compared to cash and investments of $226.4 million that were excluded from Zenith's Consolidated Balance Sheet upon the sale of CalFarm. As a result of the sale of CalFarm, the capitalization of the P&C Operations improved significantly and Zenith Insurance paid a dividend of $100.0 million to Zenith National which added considerably to the invested assets of Zenith National. REINSURANCE Zenith Insurance selectively underwrites a book of assumed reinsurance. Treaties come in a variety of forms, but the principal arrangements are either proportional in nature, in which the assuming company shares pro-rata in the premiums and losses of the cedant, or arrangements under which the assuming company pays losses in excess of a certain limit in return for a premium, usually determined as a percentage of the cedant's primary insurance premiums. Zenith operates its Reinsurance Operations as a participant in treaties in which, typically, the reinsurance coverage is syndicated to a number of assuming companies. Depending upon market conditions and other factors, the volume of premiums written fluctuates from year to year. Zenith's current participation in the reinsurance market emphasizes the reinsurance of world-wide property losses from catastrophes and large property risks. By diversifying its geographical spread, Zenith's assumed reinsurance business is written so as to limit exposure to losses from any one event in a worst-case scenario to a maximum of approximately 5% of consolidated stockholders' equity. Since the 5 inception of this operation in 1985, the average combined ratio of Zenith's Reinsurance Operations was 94.3%. REAL ESTATE OPERATIONS Zenith's Real Estate Operations develop, build and sell single-family residences in Las Vegas, Nevada. In 1999, these Operations closed and delivered 366 homes at an average selling price of $158,000, compared to 275 homes at an average selling price of $137,000 the prior year. Sales in 1999 were $58.7 million and pre-tax income was $3.6 million, compared to sales of $37.7 million and pre-tax income of $1.4 million the previous year. Construction in progress, including undeveloped land, was $87.9 million and $69.4 million at December 31, 1999 and 1998, respectively. In addition to continuing home construction, Zenith may use some land presently owned for commercial and multi-family dwelling construction. Changes in interest rates or other factors could affect future home sales (we have not seen any impact so far), but Zenith believes the land it has acquired is strategically located and will have long-term value. INVESTMENTS Zenith's Investment Operation provides investment income and realized gains on investments, primarily from investments in debt securities. Investment policies of Zenith are established by the Boards of Directors, taking into consideration state regulatory restrictions with respect to investments in connection with reserve obligations, as well as the nature and amount of various kinds of investments. Zenith's principal investment goals are to maintain safety and liquidity, enhance principal values and achieve increased rates of return consistent with regulatory constraints. The allocation among various types of securities is adjusted from time to time based on market conditions, credit conditions, tax policy, fluctuations in interest rates and other factors. See Management's Discussion and Analysis of Consolidated Financial Condition and Results of Operations -- "Investments" on pages 31-33 of Zenith's 1999 Annual Report to Stockholders, which discussion is hereby incorporated by reference. At December 31, 1999, the consolidated investment portfolio consisted primarily of taxable bonds and short-term investments supplemented by smaller portfolios of redeemable and other preferred and common stocks. The average life of the consolidated portfolio was 5.7 years at December 31, 1999. Stockholders' equity will fluctuate as interest rates fluctuate due to the classification of the changes in fair value of certain "available-for-sale" securities in stockholders' equity. Zenith has identified certain securities, amounting to 96% of the investments in debt securities at December 31, 1999, as available-for-sale. In 1999, stockholders' equity decreased by $25.7 million, net of deferred tax, as a result of changes in the fair values of such investments. PARENT Zenith is a holding company which owns directly or indirectly all of the capital stock of certain property-casualty insurance and non-insurance companies. 6 YEAR 2000 The Year 2000 Problem refers to the inability of information technology ("IT") systems and non-information technology ("non-IT") systems to accurately process dates during and after 1999. IT systems include computer hardware and software. Non-IT systems include equipment, such as elevators, security systems and HVAC systems that incorporate embedded micro controllers. If not corrected, the processes of IT and non-IT systems that are date sensitive could fail or miscalculate data resulting in disruptions of operations, such as a temporary inability to process transactions, send and receive electronic data with third parties or otherwise engage in normal business activities. There could also be a negative impact on the economic and social infrastructure on which Zenith depends. At the end of 1999, Zenith was prepared for the date change from 1999 to 2000. Zenith systematically replaced and modified its internal non-IT and IT systems to function correctly with dates from 1999 forward, thereby rendering them "Year 2000 Compliant." Zenith also had in place contingency plans to substantially reduce material business disruptions from failures of Zenith's internal systems, a failure of one or more critical third parties upon which Zenith relies in its business operations ("Key External Dependencies") and/or the contamination of Zenith's IT systems due to receipt of corrupted data. Zenith did not suffer any disruption of its business due to any impact of the date change from 1999 to 2000 on its internal non-IT systems, its internal IT systems or its Key External Dependencies. However, at the end of 1999, Zenith was cautious about the state of readiness of its Key External Dependencies and also recognized that despite its Year 2000-related efforts negative impact on its operations from Year 2000-related failures was possible. Accordingly, as a precaution, Zenith did implement elements of its contingency plans prior to the end of 1999. Those elements are no longer in effect. Although the date change from 1999 to 2000 occurred without disruption to Zenith's business, Zenith remains alert both as to potential issues in its internal systems and the state of readiness of its Key External Dependencies. All companies were, and to a lesser extent are still, faced with unknown risks arising from Year 2000 issues that may impact them negatively. Zenith believes, at this time, that the most reasonably-likely, worst-case, Year 2000 scenarios could include a failure of a part of Zenith's internal IT systems, the isolated inability of one or more of its critical Key External Dependencies, such as financial institutions, agents/brokers or reinsurers, to respond to Zenith's needs, and/or the contamination of Zenith's IT systems due to receipt of corrupted data. Such a scenario could result in a disruption of Zenith's normal business activities and could have a material adverse effect on its financial condition and results of operations. However, nothing has come to Zenith's attention leading it to conclude that there would be future Year 2000-related failures having a material adverse impact on Zenith. Further, because of the general nature of the Year 2000 Problem and how it may manifest itself, Zenith will continue to monitor its internal systems and its Key External Dependencies for Year 2000-related anomalies. Monitoring of some situations will extend into 2001, so as to cover twelve months of Year 2000 processes. However, it is expected that substantially all monitoring will decrease over the next few months and end by the second quarter of 2000. Contingency plans remain in place, ready to be implemented. The majority of Zenith's Year 2000 compliance efforts were staffed internally, although Zenith engaged technical consultants to assist its internal staff, as well as to assist Zenith in reviewing its progress. All Year 2000-related costs were funded from internal sources. The costs associated with non-IT systems and contingency planning were not significant. The costs associated with IT systems (namely, core information technology systems; computer network and communications infrastructure; and personal and laptop computers, including applications) was $11.1 million, of which $5.9 million, $2.7 million and $2.5 million were expended in 1999, 1998 and 1997, 7 respectively. The following table shows the portions of the $11.1 million that were expended for repairing Zenith's IT systems ("IT Repair Costs") and replacing them ("IT Replacement Costs"). (DOLLARS IN THOUSANDS) TOTAL IT EXPENDITURE - ---------------------- -------------------- IT Repair Costs............................................. $ 7,562 IT Replacement Costs: Software.................................................. 881 Hardware.................................................. 2,234 Related Expenditures...................................... 417 ------- Total................................................... $11,094 ======= - ------------------------ The above table includes $1.8 million incurred for the Other Property--Casualty Operations through March 31, 1999, the date on which such operations were disposed of through the sale of the capital stock of CalFarm. IT Repair Costs and IT Replacement Costs include external costs and the cost of dedicated information technology personnel. IT Repair Costs are expensed as they are incurred; IT Replacement Costs are capitalized in accordance with Statement of Position 98-1 "Accounting for the Costs of Computer Software Developed or Obtained for Internal Use." The internal cost of user participation in acceptance testing was not measured and is not included. In addition to the amounts shown in the table, Zenith will be expending funds in the first quarter of 2000 to close out and refine its Year 2000 efforts. This amount is not expected to be material. Zenith had been planning to upgrade its computer network and communications infrastructure, as well as its personal and laptop computers (including applications), for some time; however, because of the Year 2000 Problem, certain components of those plans were accelerated and completed by mid-1999. No planned information technology projects were deferred because of Year 2000-related efforts. LOSS AND LOSS EXPENSE RESERVES AND CLAIMS, AND LOSS DEVELOPMENTS The P&C Operations maintain reserves for the payment of losses and for the expenses of settling both reported and unreported claims that have been incurred under their insurance policies and reinsurance contracts. The amount of such reserves, as related to reported claims, is based upon periodic case-by-case evaluation and judgment by the P&C Operations' claims departments, with actuarial review. The estimate of unreported claims arising from accidents which have not yet been reported to the P&C Operations, commonly known in the industry as "incurred but not reported," is based upon the experience of the P&C Operations and statistical information with respect to the probable number and nature of such claims. The P&C Operations monitor these factors and revise their reserves as they deem appropriate. Reserves are based on estimates, and no assurance can be given that the ultimate liability will not be more or less than such estimates. Reference is made to Property-Casualty Loss Development on pages 40-41 of Zenith's 1999 Annual Report to Stockholders, which is hereby incorporated by reference, and the table setting forth the reconciliation of changes in the liabilities for loss and loss adjustment expenses included in Notes to Consolidated Financial Statements -- Note 16 -- "Loss and Loss Adjustment Expense Reserves" on page 62 of Zenith's 1999 Annual Report to Stockholders, both of which are hereby incorporated by reference. These tables show the development of loss and loss adjustment expense liabilities as originally estimated under GAAP at December 31 of each year presented. The accounting methods used to estimate these liabilities are described in Notes to Consolidated Financial Statements -- Note 1 -- "Summary of Accounting Policies, Operations and Principles of Consolidation" on pages 48-51 of Zenith's 1999 Annual Report to Stockholders, which note is hereby incorporated by reference. The one year loss and loss adjustment expense reserve development for Zenith's three segments of property-casualty business is set forth in the table in the Management's Discussion and Analysis of Consolidated Financial Condition and Results of 8 Operations on page 27 of Zenith's 1999 Annual Report to Stockholders, which table is hereby incorporated by reference. WORKERS' COMPENSATION Zenith's Workers' Compensation reserves, on the average, are paid within 3 years. Zenith regards the timely settlement of its Workers' Compensation claims as important to its profitability and makes use of compromises and releases for claim settlements to expedite this process. Zenith Insurance maintains three regional offices in California and offices outside of California in Florida, Texas, Arkansas, Pennsylvania, Utah, Illinois, North Carolina and Alabama, each of which is fully staffed to conduct all workers' compensation claims operations, including review of initial reports of work injury, assignment of appropriate field investigation and determination of whether subrogation should be pursued. Workers' Compensation claims operations are supported by computer systems that provide immediate access to policy coverage verification and claims records and enable Zenith Insurance to detail claims payment histories and policy loss experience reports. In 1999, loss and loss adjustment expense reserves in the former RISCORP operations were strengthened by $46.0 million as part of the RISCORP-Related Adjustment. The 1998 underwriting results include $2.0 million before tax of catastrophic workers' compensation losses. In 1997, loss and loss adjustment expense reserves were strengthened by $11.8 million for accident years 1995 and 1996. In Florida, the Special Disability Trust Fund (the "Fund") assesses workers' compensation insurers to pay for what are commonly referred to as "Second Injuries". Historic assessments have been inadequate to completely fund obligations of the Fund. In late 1997, the Florida statute was amended so that the Fund will not be liable for and will not reimburse employers or carriers for Second Injuries occurring on or after January 1, 1998. Zenith has recorded its receivable from the Fund for Second Injuries based on specific claims and historical experience prior to January 1, 1998. At December 31, 1999 and 1998, the receivable from the Fund was $37.0 million and $39.1 million, respectively, related to the pre-January 1, 1998 claims, of which $5.6 million was collected in 1999. OTHER PROPERTY-CASUALTY Zenith's Other Property-Casualty business was operated primarily by CalFarm, which was sold effective March 31, 1999. Zenith retained no liabilities with respect to the unpaid loss and loss adjustment expenses of CalFarm. In 1998 and 1997, CalFarm sustained losses before tax of $5.0 million and $1.5 million, respectively, in conjunction with California wind and storm damage. REINSURANCE Zenith expects that, on the average, its Reinsurance reserves related to casualty business will be paid in 4 years and reserves related to its property business will be paid within 1 year. In addition to information supplied by ceding companies, Zenith makes use of industry experience in arriving at estimates of ultimate losses for certain reinsurance assumed arrangements. The 1999 and 1998 Reinsurance underwriting results include catastrophe losses before tax of $18.9 million and $4.5 million, respectively. The major events of 1999 and 1998 were hurricane "Georges" and other Caribbean storms, earthquakes in Turkey and Taiwan and French storms in December of 1999. There were no catastrophes reported in Reinsurance in 1997. ENVIRONMENTAL AND ASBESTOS LOSSES The process of evaluating an insurance company's exposure to the cost of environmental and asbestos damage is subject to significant uncertainties. Among the complications are lack of historical data, long reporting delays, uncertainty as to the number and identity of insureds with potential exposure and unresolved legal issues regarding policy coverage. The legal issues 9 concerning the interpretations of various insurance policy provisions and whether environmental and asbestos losses are, or were ever intended to be, covered are complex. Courts have reached different and sometimes inconsistent conclusions regarding such issues as: when the loss occurred and which policies provide coverage, how policy limits are applied and determined, how policy exclusions are applied and interpreted, whether clean-up costs are covered as insured property damage and whether site assessment costs are either indemnity payments or adjusting costs. Zenith has exposure to asbestos losses in its Workers' Compensation Operations for medical, indemnity and loss adjustment expenses associated with covered workers' long-term exposure to asbestos or asbestos-contained materials. Most of these claims date back to the 1970's and early 1980's and Zenith's exposure is generally limited to a pro rata share of the loss for the period of time coverage was provided. Zenith also has potential exposure to environmental and asbestos losses and loss adjustment expenses beginning in 1985 through its Reinsurance Operation and through CalFarm (through March 31, 1999), which wrote liability coverage under farmowners' and small commercial policies, however such losses are substantially excluded from all such coverage. Any such liabilities associated with CalFarm were retained by CalFarm when it was sold in 1999 and Zenith retains no exposure to any such liabilities. The business reinsured by Zenith contains exclusion clauses for environmental and asbestos losses, and in 1988 an absolute pollution exclusion was incorporated into CalFarm's policy forms. All claims for damages resulting from environmental or asbestos losses are identified and handled by Zenith's most experienced claims/ legal professionals. Environmental and asbestos losses have not been material and Zenith believes that its reserves for environmental and asbestos losses are appropriately established based on currently available facts, technology, laws and regulations. However, due to the long-term nature of these claims, the inconsistencies of court coverage decisions, plaintiff's expanded theories of liability, the risks inherent in major litigation and other uncertainties, the ultimate exposure from these claims may vary from the amounts currently reserved. REINSURANCE CEDED In accordance with general industry practices, the P&C Operations annually purchase excess of loss reinsurance. Reinsurance makes the assuming reinsurer liable to the ceding company to the extent of the reinsurance. It does not, however, discharge the ceding company from its primary liability to its policyholders in the event the reinsurer is unable to meet its obligations under such reinsurance treaty. Historically, no material costs have been incurred by the P&C Operations from uncollected reinsurance. The purpose of such reinsurance is to protect Zenith from the impact of large, irregularly occuring losses. Such reinsurance reduces the magnitude of sudden and unpredictable changes in net income and the capitalization of the P&C Operations. Zenith monitors the financial condition of its reinsurers and does not believe that it is exposed to any material credit risk through its ceded reinsurance arrangements. Insurance premiums ceded by the P&C Operations amounted to $16.3 million, $54.5 million and $26.2 million in 1999, 1998 and 1997, respectively, or 4.2%, 9.3% and 5.3% of gross earned premiums in 1999, 1998 and 1997, respectively. Recoverable from reinsurers on unpaid losses amounted to $233.1 million and $245.6 million at December 31, 1999 and 1998, respectively, or 26.5% and 24.6% of gross reserves for unpaid losses and loss adjustment expenses in 1999 and 1998, respectively. The P&C Operations maintained reinsurance arrangements as follows during 1999: Workers' Compensation -- Reinsurance covered all claims between $550,000 and $100,000,000 per occurrence. The coverage from $550,000 to $5,000,000 is placed with General Reinsurance Corporation, the coverage from $5,000,000 to $10,000,000 with Employers Reinsurance Corporation and the remaining three layers from $10,000,000 to $60,000,000 primarily with NAC Reinsurance Corporation, Transatlantic Reinsurance Company, Zurich Reinsurance and the London reinsurance market (primarily Lloyd's syndicates and certain United Kingdom reinsurance companies). Catastrophe reinsurance covered an additional $40,000,000 in excess of $60,000,000 and was placed with UNUM Life Insurance Company, ReliaStar Life Insurance Company and Connecticut General Life. 10 In connection with the RISCORP Acquisition, Zenith Insurance entered into an aggregate excess of loss reinsurance agreement with Inter-Ocean Reinsurance Company, Ltd. which provides ceded reinsurance for unpaid loss and allocated loss adjustment expenses assumed by Zenith from RISCORP at April 1, 1998 up to $50,000,000 in excess of $182,000,000. Reinsurance recoverable from Inter-Ocean Reinsurance Company is secured by a trust account and an irrevocable letter of credit. Also, in connection with the RISCORP Acquisition, Zenith Insurance acquired approximately $244.3 million of reinsurance recoverables from principally quota share arrangements entered into by RISCORP. The principal reinsurers from which such amounts are recoverable are: American Re-Insurance Company, Chartwell Reinsurance Company, Continental Casualty Co., Swiss Re-Insurance Company, Trenwick Reinsurance Company and TIG Reinsurance Company. Reinsurance -- Catastrophe reinsurance covered losses of approximately $20,000,000 in excess of approximately $4,000,000 arising out of certain assumed reinsurance treaties for non-United States catastrophes. All of such catastrophe reinsurance is placed with Renaissance Reinsurance Company Limited. Zenith's exposure to losses from assumed reinsurance is limited by the terms upon which it is written to a maximum probable loss from any one event of approximately 5% of Zenith's consolidated stockholders' equity. Pooling Agreement -- The P&C Operations are parties to a pooling agreement. Under such agreement, the results of underwriting operations are ceded (the risks are transferred) to Zenith Insurance and are then reapportioned, or retro-ceded (the risks are transferred back), to the companies. At December 31, 1999, the proportions of the pooling were as follows: Zenith Insurance, 97.5%; ZNAT Insurance, 2.0%; and Zenith Star, 0.5%. Transactions pursuant to the pooling agreement are eliminated on consolidation and have no impact on Zenith's consolidated financial statements. MARKETING AND STAFF The business in the Workers' Compensation Operations is produced by approximately 2,600 independent licensed insurance agents and brokers throughout California, Florida, Texas and other states in which Zenith conducts its Workers' Compensation Operations. Zenith Insurance's assumed reinsurance premiums are generated nationally by brokers and reinsurance intermediaries. Applications for insurance submitted by all agents and brokers are evaluated by professional underwriters based upon numerous factors, including underwriting criteria and standards, geographic areas of underwriting concentration, actuarial judgments of rate adequacy, economic considerations, and review of known data on the particular risk. The P&C Operations, as opposed to their agents and brokers, retain authority over underwriting, claims processing, safety engineering and auditing. COMPETITION Competition in the insurance business is based upon price, product design and quality of service. The insurance industry is highly competitive, and competition is particularly intense in the California workers' compensation market which was deregulated with respect to prices in 1995. The P&C Operations compete not only with other stock companies, but with mutual companies and other underwriting organizations such as the State Compensation Insurance Fund in California. Competition also exists with self-insurance and captive insurers. Many companies in competition with the P&C Operations have been in business for a much longer time, have a larger volume of business, are more widely known, and/or possess substantially greater financial resources. 11 REGULATION STATE DEPARTMENTS OF INSURANCE Insurance companies are primarily subject to regulation and supervision by the department of insurance in the state in which they are domiciled and, to a lesser extent, other states in which they conduct business. The P&C Operations are primarily subject to regulation and supervision by the California Department of Insurance, except for Zenith Star, which is primarily subject to regulation and supervision by the Texas Department of Insurance. These states have broad regulatory, supervisory and administrative powers. Such powers relate to, among other things, the grant and revocation of licenses to transact business; the licensing of agents; the standards of solvency to be met and maintained; the nature of and limitations on investments; approval of policy forms and rates; periodic examination of the affairs of insurance companies; and the form and content of required financial statements. In California, Zenith Insurance and ZNAT Insurance are required to maintain on deposit investments meeting specified standards that have an aggregate market value equal to the companies' loss reserves. For this purpose, loss reserves are defined as the current estimate of reported and unreported claims net of reinsurance, plus a statutory formula reserve based on a minimum of 65% of earned premiums for the latest three years. Zenith Insurance and ZNAT Insurance are subject to similar deposit requirements in certain other states based on those states' retaliatory statutes. Detailed annual and quarterly reports are required to be filed by the P&C Operations with the Departments of Insurance in which they are licensed to transact business, and their businesses and accounts are subject to periodic examination by such agencies, usually at three year intervals. Zenith Insurance, CalFarm and ZNAT Insurance were examined by the California Department of Insurance as of December 31, 1996, and the Report of Examination contained no material findings. Zenith Star was examined by the Texas Department of Insurance as of December 31, 1996, and the Report of Examination contained no material findings. THE NATIONAL ASSOCIATION OF INSURANCE COMMISSIONERS The National Association of Insurance Commissioners ("NAIC") is a group formed by state Insurance Commissioners to discuss issues and formulate policy with respect to regulation, reporting and accounting of insurance companies. Although the NAIC has no legislative authority and insurance companies are at all times subject to the laws of their respective domiciliary states and, to a lesser extent, other states in which they conduct business, the NAIC is influential in determining the form in which such laws are enacted. In particular, Model Insurance Laws, Regulations and Guidelines (the "Model Laws") have been promulgated by the NAIC as a minimum standard by which state regulatory systems and regulations are measured. Adoption of state laws which provide for substantially similar regulations to those described in the Model Laws is a requirement for accreditation by the NAIC. In 1998, the NAIC adopted the Codification of Statutory Accounting Principles guidance (the "Codification"), which will replace the current Accounting Practices and Procedures manual as the NAIC's primary guidance on statutory accounting. (Statutory accounting is a comprehensive basis of accounting based on prescribed accounting practices, which include state laws, regulations and general administrative rules, as well as a variety of publications of the NAIC.) The Codification provides guidance for the areas where statutory accounting has been silent and changes current statutory accounting in some areas. The NAIC is now considering amendments to the Codification that would also be effective upon implementation. The NAIC has established January 1, 2001 as the effective date of the Codification. The California Department of Insurance has adopted the Codification. Implementation of the Codification may affect the surplus level and the capitalization requirements of the P&C Operations on a statutory basis. Zenith has not determined the impact of the Codification. 12 Under NAIC model regulations, insurers are required to maintain minimum levels of capital based on their investments and operations, known as "risk based capital" ("RBC") requirements. At December 31, 1999, adjusted capital under the RBC regulations for the Zenith Insurance Group (consisting of the P&C Operations) was 250%, significantly above the RBC control, or required, level of capital under the regulations. The NAIC Insurance Regulatory Information System ("IRIS") key financial ratios (11 ratios for property-casualty companies), developed to assist insurance departments in overseeing the financial condition of insurance companies, are reviewed by experienced financial examiners of the NAIC to select those companies that merit highest priority in the allocation of the regulators' resources. The 1999 IRIS results for the P&C Operations showed three results outside the "normal" range for such ratios, as such range is determined by the NAIC. These results were mainly due to decreased premium volume due to the sale of CalFarm, operating losses in the Workers' Compensation Operations and the impact of the RISCORP-Related Adjustment. INSURANCE HOLDING COMPANY SYSTEM REGULATORY ACT The P&C Operations are subject to the California and Texas Insurance Holding Company System Regulatory Acts ("Holding Company Acts"), which contain certain reporting requirements, including the requirement that such subsidiaries file information relating to capital structure, ownership, financial condition and general business operation. The Holding Company Acts also limit dividend payments and material transactions by the P&C Operations. See Item 5. for a discussion of dividend restrictions related to the Holding Company Acts. ITEM 2. PROPERTIES. Zenith Insurance owns a 120,000 square foot office facility in Woodland Hills, California which is the corporate home office of Zenith National, Zenith Insurance and ZNAT Insurance. Zenith Insurance also owns a 176,000 square foot branch office facility in Sarasota, Florida. In the regular conduct of business, Zenith Insurance, leases offices in various cities. See Notes to Consolidated Financial Statements -- Note 11 -- "Commitments and Contingent Liabilities" on pages 57-58 of Zenith's 1999 Annual Report to Stockholders, which note is hereby incorporated by reference. Zenith considers its owned and leased facilities to be adequate for the needs of the organization. ITEM 3. LEGAL PROCEEDINGS. Zenith Insurance and RISCORP entered into a settlement agreement, dated July 7, 1999 (the "Settlement Agreement"), providing for the resolution of certain claims arising out of the RISCORP Acquisition. Pursuant to the Settlement Agreement, Zenith Insurance and RISCORP (i) dismissed litigation pending between them in the United States District Courts for the Middle District of Florida, Tampa Division, and the Southern District of New York; (ii) agreed that RISCORP may request that the Neutral Auditor and Neutral Actuary (a) review an alleged error concerning the proper treatment of certain reinsurance treaties in its determinations with respect to the purchase price for the RISCORP Acquisition, without waiving whatever rights RISCORP may have to litigation of such issue, (b) determine whether the issue was properly in dispute before the Neutral Auditor and Neutral Actuary and (c), if so, determine the merits of the issue and whether a correction is appropriate; (iii) agreed that any other disputes arising under the Asset Purchase Agreement or the Settlement Agreement, including any future claims for indemnification by either Zenith Insurance or RISCORP, are to be resolved by binding arbitration; (iv) agreed that Zenith Insurance receives $6.0 million from an escrow account established pursuant to the Asset Purchase Agreement, and RISCORP receives the balance of the escrow account; and (v) agreed to an allocation between them of any recovery received as a result of refund claims that RISCORP has made to the Florida 13 Department of Labor and Employment Security, Division of Workers' Compensation. In a submission made to the Neutral Auditor and Neutral Actuary, RISCORP claimed that the purchase price for the RISCORP Acquisition should be adjusted by either $5.9 million or $23.4 million as a result of alleged errors in the original determination of the Neutral Auditor and Neutral Actuary with respect to the purchase price. On October 7, 1999, the Neutral Auditor and Neutral Actuary advised Zenith and RISCORP that they would not consider the additional issue raised by RISCORP because the issue had not previously been raised as a dispute pursuant to the procedures set forth in their engagement letter. On January 13, 2000, RISCORP filed a complaint against Zenith Insurance and the Neutral Auditor and Neutral Actuary in the Superior Court of Fulton County in the State of Georgia. The complaint alleges breach of contract against both Zenith Insurance and the Neutral Auditor and Neutral Actuary and seeks recovery of the amounts previously described to have resulted from the alleged errors by the Neutral Auditor and Neutral Actuary. Zenith is unable to predict the outcome of this litigation. Zenith National and its subsidiaries are defendants in various other litigation. In the opinion of management, after consultation with legal counsel, such litigation is either without merit or the ultimate liability, if any, will not have a material adverse effect on the consolidated financial condition or results of operations of Zenith.

In addition, any such dividend must be paid from policyholders' surplus attributable to accumulated earnings. During 1999, Zenith Insurance paid $130.0 million of dividends to Zenith National, including a $100.0 million dividend from the proceeds of the sale of CalFarm for which it received prior approval from the California Department of Insurance. During 2000, Zenith Insurance will be able to pay $29.8 million in dividends to Zenith National without prior approval. In 2000, ZNAT 15 Insurance and Zenith Star, together, will be able to pay $1.0 million in dividends to Zenith Insurance without prior approval. ITEM 6. SELECTED FINANCIAL DATA.

F-6 SCHEDULE II -- CONDENSED FINANCIAL INFORMATION OF REGISTRANT ZENITH NATIONAL INSURANCE CORP. NOTES TO CONDENSED FINANCIAL INFORMATION The accompanying condensed financial statements and the related notes should be read in conjunction with the consolidated financial statements and notes thereto of Zenith National Insurance Corp. ("Zenith National") and subsidiaries. Certain 1998 amounts have been restated to conform to the 1999 presentation. A. Investment In Subsidiaries Zenith National owns, directly or indirectly, 100% of the outstanding stock of Zenith Insurance Company ("Zenith Insurance"); CalFarm Insurance Company (through March 31, 1999, the date of its sale to Nationwide Mutual Insurance Company); ZNAT Insurance Company; Zenith Star Insurance Company; Perma-Bilt, A Nevada Corporation ("Perma-Bilt"); Zenith Development Corp. ("ZDC"); and Zenith National Insurance Capital Trust I (the "Trust"). These investments are included in the financial statements on the equity basis of accounting. Temporary advances in the ordinary course of business are included in other assets. Included in investment in subsidiaries is $2.0 million of the unamortized excess of cost over underlying net tangible assets of companies acquired prior to 1970, which is considered to have continuing value. Zenith National partially funds the cash flow requirements of its Real Estate Operations. Intercompany interest charges to such subsidiaries reduce Zenith National's interest expense. The receivable from subsidiaries mainly comprises principal and capitalized interest on loans to Perma-Bilt and ZDC of $56.8 million and $45.0 million in 1999 and 1998, respectively. Zenith National files a consolidated federal income tax return. The equity in the income of subsidiaries is net of a provision for federal income tax expense of $32.2 million in 1999, $13.2 million in 1998 and $17.5 million in 1997. Zenith has formulated tax allocation procedures with its subsidiaries and the 1999, 1998 and 1997 condensed financial information reflect Zenith's portion of the consolidated tax. Zenith Insurance paid $130.0 million of dividends to Zenith National in 1999 including a dividend of $100.0 million for which prior approval was obtained from the California Department of Insurance. Zenith Insurance paid no dividends to Zenith National in 1998 and paid dividends to Zenith National of $22.8 million in 1997. B. Senior Notes Payable Zenith National had $75.0 million of its 9% Senior Notes due 2002 (the "9% Notes") issued and outstanding as of December 31, 1999 and 1998. Interest on the 9% Notes is payable semi-annually. The 9% Notes are general unsecured obligations of Zenith National. Issue costs of $1.2 million are being amortized over the term of the 9% Notes. In each of the three years ended December 31, 1999, 1998 and 1997, $6.9 million of interest and issue costs were expended. C. Subordinated Debentures On July 30, 1998, Zenith National sold $77.3 million of 8.55% Subordinated Deferrable Interest Debentures due 2028 (the "Subordinated Debentures") to the Zenith National Insurance Capital Trust 1 (the "Trust"). The semi-annual interest payments on the Subordinated Debentures may be deferred by Zenith National for up to ten consecutive semi-annual periods. The Subordinated Debentures are redeemable at any time by Zenith at the then present value of the remaining scheduled payments of principal and interest. In 1998 Zenith used $65.0 million from the net proceeds to make a capital contribution to Zenith Insurance and used $2.3 million to acquire all of the issued voting stock of the Trust. The remaining net proceeds were used for general corporate purposes. The issue cost on the Subordinated Debentures of $0.3 million is being amortized over the term of the Subordinated Debentures.
