                                                             TO OUR STOCKHOLDERS

   Workers' Compensation markets nationally, and specifically in California
(where we write approximately half our business), have been an industry
pricing, expense and reserving disaster for the past several years. Even though
our strategy has been significantly different from most of our competitors, we
have been impacted to some extent. However, we began experiencing positive
change in 2000 which has continued into 2001; our operating losses not
withstanding.

   As a transaction-based Company, we have never believed in growth for
growth's sake, rather we have held steadfast to our customer service and profit
culture. And, throughout this difficult period, we have never wavered in our
resolve to support our four fundamental business objectives:

   1.  Deliver value-added Workers' Compensation services with underwriting
       discipline and at adequate rates to help our policyholders protect the
       safety and health of their employees, and to reduce their ultimate cost
       of insurance. Consistently-favorable loss ratios, regularly
       out-performing the industry, and a high rate of renewal customers are
       evidence of meeting this goal.

   2.  Attract and train a professionally managed employee team, with an
       understanding of our strategies, and the resolve and courage to execute
       our plan.

   3.  Maintain financial strength, documented by an excellent balance sheet
       and cash and securities in the holding company, and high quality ratings
       from rating agencies.

                                                                    TheZenith

                                                                               3

   THE LONG PERIOD OF INADEQUATE PRICING IS APPARENTLY COMING TO AN END; WE
   HAVE EXPERIENCED AN INCREASE IN BUSINESS FOR THE FIRST TIME IN SEVEN YEARS
   AT OUR ACTUARIAL PRICES.

   4.  Provide long-term investor value as reflected by growth in our stock
       price and stockholders' equity.

A PERIOD OF CHARACTER BUILDING

   The current period of adverse industry results has its roots in the Workers'
Compensation markets of the early 1990's. On the one hand, there was a degree
of positive legislative reform, some rate improvement in various states and
reserve adequacy. Plus, the industry's and employers' surprisingly effective
assault on fraud and abuse in the system saved hundreds of millions of dollars,
resulting in favorable frequency trends and underwriting results. On the other
hand, there was the advent of open rating in California in 1995, and adverse
insurer pricing trends elsewhere, resulting in plunging employer costs and
unsatisfactory insurer results. As I reported last year, it was the best of
times and the worst of times.

   But, the major trend of inadequate pricing was escalating and the
foreseeable catastrophic damage to insurers was becoming evident.

   Operating as if oblivious to escalating benefits and increased healthcare
and claims costs, masked, in part, by declines in claim frequency, numerous
opportunistic competitors attacked the market with selling prices below cost as
if there was no tomorrow. Market shares were built with inadequate pricing,
de-engineered policyholder services, naive reinsurance and unrealistic
reserving. It was growth for growth's sake at the expense of solvency and
financial strength, with adverse ramifications, as well, to

carriers committed to customer service and profitability like TheZenith. As
could reasonably be anticipated, the competitors' strategies did not work, and
negative financial and regulatory consequences have become apparent.

   More specifically:

- - Industry combined ratios grew to 130-135%; more than 150% in California.

- - Healthcare and claims management costs increased at a rate of 5%-6%;
  double-digit in California.

- - California's "treating physician presumption," for example, was intended to
  reduce the number of medical reports required to evaluate an injury.
  Unintended result: we are now limited in our ability to rebut a medical
  analysis that may not be accurate, leading to substantial increases in the
  cost of an average claim.

- - Industry has estimated under-reserving of $18 billion; $5 billion in
  California as prior-period loss development continues to escalate.

- - Unprecedented underwriting losses and diminishing balance sheets forced the
  California regulators to takeover a large competitor, require the sale of
  another, and restrict operations of others.

- - Competitors, fighting to survive their sins of the past, answered with
  pricing and reserving increases significantly in excess of ours; especially
  in the California marketplace.

                                                                    TheZenith

                                                                               5

   AS A TRANSACTION-BASED COMPANY, WE HAVE NEVER BELIEVED IN GROWTH FOR
   GROWTH'S SAKE, RATHER WE HAVE HELD STEADFAST TO OUR CUSTOMER SERVICE AND
   PROFIT CULTURE.

   During this period, we responded with acquisition and geographic
diversification, the sale of CalFarm at an attractive profit, recruiting an
improved management team, and substantial investment in information technology
to cost-reduce our G&A (primarily in claims management where the majority of
premium is spent). Tough-minded value propositions were applied to every
expense factor throughout our operations. We gradually reduced our employee
census, held firm to transaction-based pricing, and maintained underwriting and
reserving discipline. Of interest, we were the only company to reduce premiums
in California for six consecutive years.

   To say it was a time of character building is an understatement. With tens
of thousand of applications submitted to us throughout our national network of
offices over the years, can you imagine the frustration of our people almost
always having to say "no?" No to unprofitable pricing. No to unrealistic
underwriting. No to inadequate reserving. No to dismantling our policyholder
services. In essence, "no" to a substantial percentage of our new business
development and renewal opportunities, but in a professional manner so that
agents and employers would continue to do business with us when markets
changed. As a result, we reduced premium volume and market share. Our expenses,
as expected, were disproportionate to our revenues resulting in operating
losses. But, what if we had followed the unrealistic pricing of the market? Our
operating losses would have been far more serious and our underwriting
discipline would have been damaged. As

   [GRAPH]                                                                         [GRAPH]


a result, our loss ratios continue to be substantially better than industry
averages, and now provide a favorable starting point for future performance.

   In summary, there are indications the long period of inadequate pricing is
apparently coming to an end. During 2000, and so far in 2001, TheZenith has
experienced an increase in business for the first time in seven years at our
actuarial prices. Of significance, our value-added service strategy is more in
demand at appropriate prices in several regions of the country. Although
unrealistic pricing and underwriting continues in various markets, it is to a
lesser extent than in the past.

   Lastly, we hold firmly to our fundamental belief that operating with an eye
to the long term is the correct strategy. TheZenith is stronger in many ways
than at any time during this Management's 23-year tenure. Our 2000 Report will
discuss in detail the major issues impacting our current and future operations,
and our efforts to return to profitability.

SUMMARY OF FINANCIAL HIGHLIGHTS:

- - Workers' Compensation premiums earned increased 10% to $300.8 million.

- - Operating losses after tax were $37.7 million, or $2.19 per share in 2000,
  compared to $55.2 million, or $3.22 per share in 1999.

- - Investment income after tax was $34.2 million, or $1.98 per share in 2000,
  compared to $35.6 million, or $2.07 per share in 1999.

- - Realized losses on investments after tax were $10.1 million, or $0.58 per
  share, compared to gains of $5.0 million, or $0.29 per share in 1999.

                                                                    TheZenith

   OUR RECENT RESULTS ARE UNSATISFACTORY, BUT IF WE HAD FOLLOWED THE
   UNREALISTIC PRICING OF THE MARKET, OUR OPERATING LOSSES WOULD HAVE BEEN FAR
   MORE SERIOUS.

   Unrealized losses on fixed maturities and equity securities, recorded as a
   reduction of stockholders' equity after tax, were $8.2 million, compared to
   $20.0 million in 1999. Also, we have a deferred gain after tax of $3.3
   million, or $0.19 per share, in connection with an installment sale of real
   estate.

- - Net loss was $46.8 million, or $2.71 per share in 2000, compared to net
  income of $54.1 million, or $3.15 per share for 1999.

- - The combined ratio for the property-casualty operations was 130.2% for 2000,
  compared to 135.2% for 1999.

- - Stockholders' equity per share at December 31, 2000 was $17.76, compared to
  $20.67 at December 31, 1999.

ANALYSIS

   Net loss was $46.8 million, or $2.71 per share in 2000, compared to net
income of $54.1 million, or $3.15 per share the prior year.

                                                                         [GRAPH]

   2000 results were significantly below our goals, due primarily to continuing
underwriting losses in the Workers' Compensation operations, and adverse
reserve development of 1999 reinsurance losses. The 1999 results were impacted
by the $50.0 million purchase price adjustment in connection with the RISCORP
acquisition coupled with underwriting losses in the Workers' Compensation
operations.

   Our combined ratio for the Workers' Compensation operations was 129%,
composed of a 70% accident year loss ratio (compared to 71% for the current
estimate of last year), a 57% loss adjustment and underwriting expense ratio
and a 2% ratio of prior years' reserve strengthening. Since the beginning of
California's open-rating in 1995, our California loss ratio has averaged 68%,
compared to 101% for the California industry. Our 33-point advantage is better
than TheZenith's comparative results prior to open rating, and demonstrates the
discipline of our pricing and underwriting strategy during a period of
significant market turmoil.

   2000 accident year Reinsurance operations were excellent, but were impacted
by adverse loss development on the large losses of prior years.

   Investment income after tax decreased slightly to $34.2 million, or $1.98
per share in 2000, from $35.6 million, or $2.07 per share in 1999.

   Stockholders' equity at December 31, 2000 was $309.8 million, compared to
$354.6 million at December 31, 1999.

   Cash used in operating activities was $47.0 million in 2000, compared to
$51.6 million in 1999; primarily due to payment of claim liabilities.

                                                                    TheZenith

   QUARTERLY RESERVING REVIEWS AND RATE ADJUSTMENTS WILL
   KEEP US FOCUSED ON CHANGING TRENDS.

   We purchased 2,000 shares of Zenith common stock during 2000, leaving
authority to purchase an additional 938,000 shares. Since 1987, we have
repurchased 8,009,000 shares, or an estimated 38% of the shares then issued,
for an aggregate cost of $150.8 million, or an average of $18.82 per share.

   At December 31, 2000, Zenith had long-term debt of $58.4 million, compared
to $74.7 million at December 31, 1999, with a total debt-to-equity position of
19.3%, compared to 21.1% at December 31, 1999. Also outstanding was $65.6
million of 8.55% Capital Trust Securities issued in July 1998, maturing in 28
years. We repurchased $24.5 million of debt securities in 2000. TheZenith's
parent company had $70.0 million of bank lines of credit available, and $135.7
million of investments. In order to maintain the financial strength of our
insurance subsidiaries, we contributed $25.0 million to capital in the fourth
quarter of 2000.

   Zenith's subsidiaries are rated A (Excellent) by A.M. Best Company. Moody's
Investor's Service and Standard & Poor's have assigned an insurance financial
strength rating of Baa1 (Adequate) and A (Strong), respectively.

   Information in the following table provides estimates of Zenith's net
incurred losses and loss adjustment expenses by accident year, evaluated in the

accuracy of our reserve estimates, as well as providing a guide to the setting
of fair prices and rates. The increase in estimated incurred losses between
1997 and 1998 is mainly attributable to the business acquired from RISCORP and
the increase from 1998 to 1999 is primarily a result of the reserve increase
that was part of the RISCORP purchase price adjustment referred to in prior
reports. Our reserves are not discounted.

INVESTMENTS

   Investment activities are a major part of our revenues and earnings; we
believe our portfolio is diversified to achieve a reasonable balance of risk
and a stable source of earnings. Zenith primarily invests in debt securities,
as compared to equities, and our largest holdings are U.S. Government
securities. In comparison to other insurers, we believe that our portfolio
contains a smaller percentage of equities to total assets and a larger
percentage of cash or short-term securities.

- - Consolidated investment income after tax and after interest expense was $30.6
  million, or $1.77 per share in 2000, compared to $30.3 million, or $1.76 per
  share in 1999. Average yields on this portfolio in 2000 were 5.9% before tax
  and 3.9% after tax, respectively, compared to 5.5% and 3.7%, respectively, in
  1999.

- - During 2000, we recorded net losses before tax from our investment portfolio
  of $15.5 million, compared to $7.7 million of gains the prior year. The
  losses were primarily a result of write downs of bonds originally acquired as
  investment grade securities, most of which continue to pay interest.

- - Pre-tax income during 2000 from our real estate activities was $5.5 million,
  compared to $3.6 million the prior year.

   THEZENITH IS POSITIONED TO PROVIDE COVERAGE FOR NEW AND EXISTING CUSTOMERS,

   POLICYHOLDER SERVICES.

- - Unrealized losses in our portfolio of fixed maturity investments were $14.5
  million before tax in 2000, compared to $30.1 million before tax the prior
  year.

   Our investment portfolio is recorded in the financial statements primarily
at market value. Average life of the bond portfolio was 5.3 years at December
31, 2000, compared to 6.2 years at December 31, 1999. Portfolio quality is high
with 94% and 95% rated investment grade at December 31, 2000 and 1999,
respectively.

   The major developments in the U.S. bond markets were continued low inflation
and declining interest rates on Treasury Securities. Corporate bond spreads in
relation to Treasury Securities increased, notwithstanding most high-quality
corporate categories gained in price. Since we are capable of holding these
investments to maturity, and the average maturities are relatively short,
fluctuations in bond values do not significantly impact our operations.

   Short-term investments and liquidity remained high as we searched for
intelligent investment opportunities, and avoided large losses in certain
equity markets.

*Equity securities at cost


   In 1993, we started a home-building operation in order to participate in the
growth of the Las Vegas, Nevada housing market. During 2000, we closed and
delivered 469 homes at an average selling price of $177,000, compared to 366
homes at an average selling price of $158,000 the prior year. Sales of $84.5
million and $5.5 million of pre-tax income were recorded during 2000, compared
to sales of $58.7 million and $3.6 million of pre-tax income the previous year.
Land presently owned at a cost of $34.5 million will support the construction
of an estimated 1,300 homes over the next several years.

   OUR VALUE-ADDED SERVICE STRATEGY IS MORE IN DEMAND AT APPROPRIATE PRICES IN
   SEVERAL REGIONS OF THE COUNTRY.

   Changes in interest rates or other factors could affect future home sales
(we have not seen any impact so far), but we believe the land we have acquired
is strategically located and has long-term value.

   An agreement was consummated to sell our Las Vegas strip property for a gain
of $6.0 million, of which $5.1 million will be deferred until additional
payments are received. At the closing we received $7.3 million in cash and
first mortgage notes for the balance, of which $7.7 million has been adequately
guaranteed. We will own a 25% interest in the joint venture owner of the
property which will be managed by a successful developer.

WORKERS' COMPENSATION

   TheZenith is a specialty insurer with primary operations in California,
Florida, Texas and 40 other states. Premiums written in 2000 were $308.1
million, an increase of 15% from the prior year. Underwriting losses were $87.9
million in 2000 and $122.5 million in 1999. At year-end 2000, there were 32,400
policies in force.

   Even though our underwriting losses are significant and unacceptable, they
are not a result of either inadequate rates or a lack of underwriting
discipline. In our case, TheZenith's strategy, compared to the competition,
resulted in less revenue than needed to achieve a reasonable expense ratio.

                                                                    TheZenith

   OUR ACCIDENT YEAR LOSS RATIOS ARE SUBSTANTIALLY BELOW INDUSTRY AVERAGES AND

   Our accident year loss ratios, as currently estimated, continue to be
substantially below industry averages, as follows:

1997                                 67%              101%               49%               72%

1998                                 67%              110%               59%               80%

   One of the many reasons why our loss ratios outperform the industry is that
we rely upon our actuaries to establish adequate rates. Except in Florida,
where minimum rates are established by the Insurance Commissioner, most of our
business is written at rates we establish and adjust based upon sound actuarial
data and judgment which includes estimates of future cost trends. This strategy
penalizes volume when competitors ignore data and trends, and price for growth,
but assists us in producing low loss ratios and maintaining our discipline.

   As we wrote in last year's Report, competitors (particularly in California)
began raising rates and adjusting underwriting to improve their profitability
at substantially higher prices than TheZenith. We expected these changes to
gain momentum and allow us to write more business. Our predictions were

correct, with our 2000 inforce California volume increasing 50%, from
$98.1 million to $146.7 million. Markets outside California were not as
favorable, however, we increased premium from $145.8 million to $162.4 million.

   Along with the pricing changes, the most significant development last year
was the continued deterioration in the estimated 1999 results of the industry.
At the beginning of last year, California and U.S. indications were combined
ratios in the 150% and 125% ranges, respectively, for 1999. Today these
estimates have been increased to 156% and 135%, respectively. From a historical
point of view, these are large changes in a very short period of time and are
the worst combined ratio increases on record. As a result, continuing and
significant price increases will be required to restore the industry's
financial health, and individual companies will need to be vigilant as to
pricing, underwriting and loss reserve adequacy. Firmer pricing will also be
supported by lower interest rates.

   Pricing wars, naive reinsurance capacity, and escalating claims costs of
recent years have taken their toll. Substantial increases in estimating prior-
accident-year loss reserves are commonplace. California regulators have
initiated the following actions against three large Workers' Compensation
carriers: a take-over, restrictions and reduced mandated writings, and pricing
activity intervention. Two other California competitors have ceased business,
as well as Reliance Insurance Co., a large writer in the marketplace. But,
soft-market problems may be far from over. Continuing

                                                                    TheZenith

                                                                              17

price increases, upward loss reserve adjustments, and financial difficulties
will persist. Add to this a major unknown: claim frequency trends. While they
were favorable during the first nine months of 2000, what if they increase
before the industry returns to financial stability?

   We are not aware of any definitive data as to why claim frequency trends
have been favorable for the last several years. It is possible that the positive
economy is one of the reasons. If so, we are mindful that it is slowing and, in
California, current energy problems may impact jobs and the economy.
   TheZenith is positioned to provide coverage for new and existing customers,
responsibly and profitably, while delivering quality, value-added policyholder
services. Compare January 2001 with 2000: we wrote approximately $40.0 million
of new business, compared to approximately $18.0 million the prior year, and
renewed a large percentage of existing policies at our actuarial prices. In
California, where pricing flexibility exists, we increased our sales in all
regions of the state at prices averaging 25% more than the prior year. Combined
ratio improvement will be a result of volume and price increases in concert
with continuing expense control. Profit improvement should be augmented by
increases in cash flow and investable assets. Quarterly reserving reviews and
rate adjustments (versus annual reviews as practiced by many competitors), will
keep us focused on rising healthcare and indemnity claims costs. Again, the
frequency and severity of new claims, along with reserve adequacy estimates,
will determine the timing and magnitude of our on-going performance improvement.

   EMPLOYERS WANT TO KEEP THEIR COSTS TO A MINIMUM AND OUR SERVICES, TOGETHER
   WITH SAFETY PRACTICES, ARE ESSENTIAL.

   Incredibly, there are still a number of competitors significantly under-
pricing accounts, with managing general agents, reinsurers and not-for-profit
companies the major discounters. While their impact will be far less than in
recent years, one would think the "message" would have been received by now.
Unfortunately, it is easy to predict the discounters will continue to erode
their financial performance, and their ability to provide needed services to
assist employers in controlling their costs.

   Reducing employer loss ratios, experience modifications, and ultimately the
long-term cost of their insurance is our hallmark and our mission. TheZenith's
value-added services, implemented in partnership with our policyholders, have
an excellent record of delivering against these objectives, and constitute the
Company's most valuable asset along with our highly-professional staff.

- - Expert Safety and Health programs assist with accident and illness
  prevention, incident investigation and remediation, and safe-work practices
  education for management and employees.

- - Claims and Medical/Disability Management procedures facilitate prompt injury
  reporting, the use of recommended physicians (where permitted
  state-by-state), nurse case management of serious claims, analysis and
  negotiation of hospital and medical bills, and continuing communications and
  reviews to monitor and manage recoveries, costs and reserving.

- - Special Investigation Unit and specialized Workers' Compensation Legal

  prudent, and represent policyholders throughout the litigation process as
  appropriate.

   WE DO NOT FORECAST FUTURE FINANCIAL RESULTS AS A MATTER OF POLICY, BUT IT
   WOULD APPEAR REASONABLE TO SEE IMPROVED OPERATING RESULTS IN THE SHORT TERM.

- - Return to Work programs place recovering employees in transitional duties
  with physician approval, improving employer morale and productivity, while
  containing costs.

- - Premium Auditors provide proper payroll classifications to assure accuracy
  and avoid unanticipated retroactive billing.

   Politically, significant changes affecting our operations were minimal. In
California, a major benefit increase bill with sorely needed reforms was
understandably vetoed by the Governor for the second year in a row. Future
efforts towards reform of the system will be made this year, hopefully with the
cooperation of the Governor. We are mindful this task has been made more
difficult by the enactment of musculoskeletal regulations and ergonomic
standards by the Occupational Safety and Health Association (OSHA) in
Washington. These regulations add significant costs to employers over and above
the price of Workers' Compensation, and it is anticipated until the legality
and costs of these regulations is determined, it may be difficult for labor and
business to negotiate with the politicians for needed Workers' Compensation
changes. Obviously, employers are sensitive to the cost of any benefit package;
we too are concerned with the need for a gradual phase-in of benefits and its
equitable distribution among disability ratings in order that claim frequency
not be increased. We continue to be active in these negotiations because it is
essential to eliminate the treating physician presumption from the California
system in order to control

   MOST VALUABLE ASSETS.

escalating costs. Also, we desire changes that will speed up the dispute
resolution process and make it less costly.

   Lastly, legislative consideration should be given to the role played by the
State Fund in the California marketplace. The State Fund is the largest writer,
a fierce competitor in certain risks, and during this past year, seems to be
the most growth-oriented participant. Since the spread between their rates and
the general market rates is so large, it is quite likely they are not in
compliance with statutes requiring them to be "fairly competitive." These
statutes predate open rating in California, and at the least the Legislature
should provide some objective criteria of "fairly competitive," since it is the
legislative intent that the State Fund "become neither more nor less than
self-supporting." At present the State Fund continues to report operating
losses, and if this continues or escalates, there will be an adverse impact on
the California market. Our concerns are not about competing with the State
Fund, but about the rules under which they operate and are regulated.

   As a result of the large insolvency of one of the competitors, it is
expected that the California Insurance Guarantee Association will be required
to fund hundreds of millions of dollars of losses. Each of our policyholders
(all policyholders in the State) will be assessed, under current law, at 1% of
their premiums for these losses. Furthermore, we expect there will be efforts
to obtain an increase in the assessment amount. Obviously, if other companies
become insolvent there will be additional serious financial and political
problems.

                                                                    TheZenith

   REINSURANCE PREMIUM INCREASES AND MORE FAVORABLE TERMS ARE OCCURRING FROM
   THE 1999 LOSSES, PARTICULARLY IN THE RETROCESSION MARKET WHERE WE ARE ACTIVE.

REINSURANCE

   For the past 15 years, Zenith Insurance has been selectively underwriting
assumed treaty and facultative reinsurance. Reinsurance represents 11% of our
property-casualty volume, while Reinsurance reserves represent 15% of our total
property-casualty reserves.

   During 2000, the net written premium of this operation was $39.3 million,
compared to $35.9 million in 1999. Earned premium was $37.9 million, compared
to $36.4 million in 1999. Underwriting losses of $14.5 million were recorded in
2000, resulting in a combined ratio of 138.3%, compared to an underwriting loss
of $7.3 million and a combined ratio of 120.1% the prior year. Since the
inception of this operation in 1985, the combined ratio has averaged 97.4%.
During 2000 and 1999, the majority of written premium was derived from
worldwide property catastrophe business.

   Accounting for the property catastrophe reinsurance business has a different
result from our other property-casualty business. At the end of each reporting
period, income is recognized without reserves being established if no major
catastrophe has occurred. In our other businesses, reserves are mandated based
upon actual events as well as expected loss patterns. As a result, there may be
large fluctuations (positive or negative) in underwriting results for the
property catastrophe reinsurance business in the short-term, since only actual
events are considered. In 1999, the largest storm impacts were Hurricanes Floyd
and Anatol, Typhoon Bart in Japan,

and French windstorm losses on December 26, 27 and 28, 1999. It was difficult
to evaluate our losses from these events in 1999 and, therefore, additional
losses were recorded this past year. Fortunately in 2000, there do not appear
to have been significant events causing losses. Nevertheless, premium increases
and more favorable terms are occurring from the 1999 losses, particularly in
the retrocession market where we are active.

INFORMATION TECHNOLOGY

   We focused on two areas this past year: first, improving the functionality
of our claims systems with technology and second, our Intranet capability.
Additionally, we are making progress toward consolidating our three separate
systems into a single national network. Work in all these areas will continue
in 2001 and beyond as we insist on improving productivity.

DIRECTORS AND OFFICERS

   Significant strength was added to our Board of Directors and management team
this past year. Leon Panetta, Founder and Director of the Leon & Sylvia Panetta
Institute for Public Policy, and formerly White House Chief of Staff, joined
our Board. His wisdom and judgement, along with all of our Directors, have
already made valuable contributions.

   Wes Heyward and Kari Van Gundy, formerly President and Financial Senior Vice
President, respectively, of CalFarm Insurance, have re-joined us in senior
management positions. Also, Steve Pratt was appointed as Senior Vice President,
Claims to supervise our claims operation nationwide.

                                                                    TheZenith

   WE HAVE THE FINANCIAL AND INTELLECTUAL STRENGTH TO TAKE ADVANTAGE OF THE
   CURRENT MORE POSITIVE PRICING TRENDS.

CONCLUSION

   We are optimistic about the opportunities available in the Workers'
Compensation market at our actuarial prices after many years of significantly
inadequate pricing and turmoil. Our intellectual and financial strengths are
excellent and we are benefiting from the patience and discipline we
demonstrated during the last several years. And, we are constantly focused on
improving the quality of the services provided to our customers and improving
our productivity, since both are essential to our continued success.

   While it is not our policy to forecast future financial results, it would
appear reasonable to predict improved operating results in the short term.

   We appreciate the confidence of our long-term investors and welcome our new
Shareholders as we navigate through the more favorable market conditions to
restore profitability. The support, guidance and good judgment of our
distinguished Directors provide assistance and confidence to our management
team in our efforts to enhance Shareholder value.

controlling medical, legal and rehabilitation costs, as well as fraud and abuse;
and (7) other risks detailed herein and from time to time in Zenith's other
reports and filings with the Securities and Exchange Commission.

OVERVIEW

   Zenith's long-term source of consolidated earnings is principally the income
and investment income from the operation of its property-casualty insurance
businesses ("P&C Operations") and its investment portfolio. The P&C Operations
comprise Workers' Compensation, Reinsurance and Other Property-Casualty (through
March 31, 1999). 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. During 2000, the P&C Operations
wrote workers' compensation insurance in 43 states but the largest
concentrations, 45.7% and 28.2% of the Workers' Compensation premiums earned
during 2000, were in California and Florida, respectively. Reinsurance
principally consists of world-wide, assumed reinsurance of property losses from
catastrophes and large property risks. Results of the Reinsurance Operations can
be adversely impacted in periods that sustain large catastrophe losses. Other
Property-Casualty, which was operated by CalFarm Insurance Company ("CalFarm"),
formerly a wholly-owned subsidiary of Zenith Insurance Company ("Zenith
Insurance"), a wholly-owned subsidiary of Zenith National Insurance Corp.
("Zenith National"), represents multiple product line direct insurance other
than workers' compensation, principally in California. Effective March 31, 1999,
Zenith sold CalFarm. Results of the P&C Operations for the three years ended
December 31, 2000 are set forth in the table on page 27. The Real Estate
Operations develop land and primarily construct single-family residences in Las
Vegas, Nevada. Investment operations provide income and realized gains on
investments, primarily in debt securities. The Parent operations represent
Zenith National, a holding company which owns, directly or indirectly, all of
the capital stock of

                                                                    TheZenith 25

the P&C Operations, non-insurance companies and securities.

   The comparability of the results of operations between each of the three
years ended December 31, 2000, 1999 and 1998 is affected by several items.
First, 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"-- for a full description of the RISCORP Acquisition,
see Note 14 to the Consolidated Financial Statements on pages 58-59). Second, in
the third quarter of 1999, Zenith recorded net charges of $50.0 million before
tax ($32.5 million after tax, or $1.89 per share) associated with an increase in
the estimated net liabilities for unpaid losses and loss adjustment expenses
acquired from RISCORP (the "RISCORP Purchase Adjustment"-- for a full
description of the RISCORP Purchase Adjustment, see Note 14 to the Consolidated
Financial Statements on pages 58-59). Third, effective March 31, 1999, Zenith
sold CalFarm which had previously operated Zenith's Other Property-Casualty
Operations. The sale of CalFarm resulted in a gain of $104.3 million after tax
(see Note 13 to the Consolidated Financial Statements on pages 57-58).

ended December 31, 2000 are set forth in the following table:

   Zenith's key operating goal for the P&C Operations is to achieve a combined
ratio of 100% or lower. The combined ratio, expressed as a percentage, is the
key measure of underwriting profitability traditionally used in the
property-casualty insurance business. It is the sum of net incurred loss and
loss adjustment expenses, underwriting expenses and policyholders' dividends,
expressed as a percentage of net premiums earned.

   The profitability of the P&C Operations is principally dependent upon the
adequacy of rates charged to the insured for insurance protection; the frequency
and severity of claims and catastrophes; the ability to accurately estimate and
accrue reported and

                                                                    TheZenith 27

unreported losses in the correct period; and the ability to manage claim costs
and keep operating expenses in line with premium volume. Some of the factors
that continue to impact the business and economic environment in which Zenith
operates include: intense price competition; poor operating results and reports
of substantial under estimation of reported loss reserves in the national
workers' compensation insurance industry; an uncertain political and regulatory
environment, both state and federal; the outlook for economic growth in
geographic areas where Zenith operates; the frequency and severity of claims and
catastrophes; and the changing environment for controlling medical, legal and
rehabilitation costs, as well as fraud and abuse. Fluctuations in interest rates
cause fluctuations in Zenith's investment income and the fair values of its
investments. Although management is currently unable to predict the effect of
any of the foregoing, these factors, related trends and uncertainties could have
a material effect on Zenith's future operations and financial condition.

   The amount by which estimated losses, measured subsequently by reference to
payments and additional estimates, differ from those originally reported for a
period is known as "development." Development is favorable when losses
ultimately settle for less than the amount reserved or subsequent estimates
indicate a basis for reducing reserves on open claims. The following shows the
one-year loss reserve development for loss and loss adjustment expense for the
P&C Operations:

   Zenith continually monitors loss development trends and data to establish
adequate premium rates and loss reserves. In 2000, Zenith increased its estimate
of unpaid Workers' Compensation losses for principally the 1999 accident year by
about $8.0 million. The Workers' Compensation reserve strengthening in 1999 is
attributable to the RISCORP Purchase Adjustment. Adverse development in 2000 in
the Reinsurance Operations is attributable to additional estimates of the impact
of the events in 1999 but there do not appear to be any major catastrophic
events in 2000. Adverse development in the Reinsurance Operations in 1999 was
principally attributable to increased estimates in 1999 of the loss associated
with Hurricane Georges, the principal catastrophe in 1998.

   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
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 and exclusions are applied and determined,
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 the Workers' Compensation
Operations for medical, indemnity and loss adjustment expenses associated with
covered workers' long-term exposure to asbestos or asbestos-containing
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 workers'
compensation-related 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 Operations but the
business reinsured by Zenith in its Reinsurance Operations contains exclusion
clauses for environmental and asbestos losses. CalFarm (through March 31, 1999)
wrote liability coverage under farmowners' and small commercial policies,
however any such liabilities associated with CalFarm were retained by CalFarm
when it was sold and Zenith retains no exposure to any such liabilities. All
claims for damages resulting from 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 decisions on
coverage, plaintiffs' 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.

   Inflation rates may impact the financial statements and operating results in
several areas. Fluctuations in inflation rates impact the market value of the
investment portfolio and yields on new investments. Inflation also impacts the
portion of the loss reserves that relates to hospital and medical expenses and
property claims and loss adjustment expenses, but not the portion of loss
reserves that relates to workers' compensation indemnity payments for lost wages
which are fixed by statute. Adjustments for inflationary impacts are implicitly
included as part of the P&C Operations' continual review of property-casualty
reserve estimates. Actuarial account of increased costs is considered in setting
adequate rates, and this is particularly important in the health care area where
hospital and medical inflation rates have exceeded general inflation rates.
Operating expenses, including payrolls, are impacted to a certain degree by the
inflation rate.

WORKERS' COMPENSATION

   The following is a discussion of results of the Workers' Compensation
Operations as set forth on page 27 excluding the impact of the RISCORP Purchase
Adjustment in 1999.

   In the three years ended December 31, 2000, intense competition and
inadequate premium rates adversely affected the national workers' compensation
industry. Industry data indicates a national trend of increasing claims
severity, and premium rates have not kept pace with the trend of increasing
severity. Industry organizations such as the National Council on Compensation
Insurance, Inc. and the California Workers' Compensation Insurance Rating Bureau
have reported that their analyses of the data show that the liabilities for
unpaid loss and loss adjustment expenses as estimated and reported by the
industry are significantly inadequate. The estimated accident year combined
ratio in 1999 was about 135% for the national workers' compensation industry and
about 156% for the California workers' compensation industry, including a 1999
accident year loss ratio of about 118%.

                                                                    TheZenith 29

   Zenith's inforce Workers' Compensation premiums decreased consistently in the
several years ended December 31, 1999 as a result of Zenith's endeavors during
that period to maintain rate adequacy in the face of intense competition in the
national workers' compensation insurance industry and, as a result, premiums
earned in the Workers' Compensation Operations decreased in 1999 compared to
1998. In the year ended December 31, 2000, competitive pricing conditions
improved somewhat in California and Zenith increased its inforce premiums in
California by about 50% at December 31, 2000 compared to December 31, 1999.
Outside of California, where competition and pricing are improving only
moderately and only in certain states, Zenith's inforce premiums increased by
about 11% at December 31, 2000 compared to December 31, 1999. As a result,
Zenith's Workers' Compensation premiums earned increased in 2000 compared to
1999. In January 2001, Zenith continued to increase its inforce premiums in
California and other selected states.

   Zenith increased its premium rates in California by about 8% effective
January 1, 2000 and by about 9% effective September 1, 2000. Rates were
increased again in California by about 8% effective January 1, 2001 and Zenith
implemented other rate increases in most of the states in which it does
business. Minimum rates in Florida, which are set by the Department of
Insurance, were unchanged at January 1, 2001.

   Underwriting losses in the Workers' Compensation Operations increased in 2000
compared to 1999 principally because of a higher loss ratio in 2000. The
increase in the loss ratio is due to the trend of increasing severity of claims
in Zenith's Workers' Compensation Operations offset partially by a decrease in
frequency of claims and by rate increases in California. Zenith continually
monitors loss development trends and data to establish adequate rates and loss
reserves. Zenith also increased its estimate of California losses for prior
years, principally for 1999, and about $8.0 million of reserve strengthening is
included in the loss ratio and underwriting loss in 2000. Underwriting losses in
the Workers' Compensation Operations increased in 1999 compared to 1998
principally because of a higher loss ratio in 1999 and the impact of reduced
premium volumes in 1999 relative to operating expenses.

   Zenith expects that the profitability of its Workers' Compensation Operations
will be dependent upon general levels of competition, industry pricing and
management's ability to estimate the impact of claim frequency and severity
trends on the adequacy of loss reserves and premium rates. Zenith is unable to
predict when its Workers' Compensation Operations will return to underwriting
profitability, although it anticipates improvement in the short-run with
increases in volume and prices.

   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 Insurance 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, 2000
and 1999, the receivable from the Fund was $31.1 million and $37.0 million,
respectively, related to the pre-January 1, 1998 claims.

REINSURANCE

   Results of the Reinsurance Operations may be adversely impacted in years when
large catastrophes occur. However, since its inception in 1985, the combined
ratio of the Reinsurance Operations through December 31, 2000 was 97.4%. In the
three years ended December 31, 2000, the Reinsurance Operations were adversely
impacted by catastrophe losses. Catastrophe losses were $22.6 million,
$18.9 million and $11.5 million before tax in 2000, 1999 and 1998, respectively.
Catastrophe losses in 2000 were attributable to additional estimates of the
impact of the events in 1999, but there do not appear to have been any major
catastrophes in 2000. There were frequent catastrophes of a moderate size
culminating in severe storms in Europe at the end of 1999. Catastrophe losses in
1998 were attributable principally to a single large event--Hurricane Georges.
Estimates of the impact of catastrophes on the Reinsurance Operations are based
on the information that is currently available and such estimates could change
based on new information that becomes available or based upon reinterpretation
of existing information.

OTHER PROPERTY-CASUALTY

   The Other Property-Casualty Operations, through CalFarm, offered automobile,
farmowners, commercial coverages, group health and homeowners coverage,
primarily in California. CalFarm was sold, effective March 31, 1999, to
Nationwide Mutual Insurance Company resulting in a gain of $104.3 million after
tax.

   Underwriting results for 1999 and 1998 were impacted by intense competition
and increased expenses, primarily due to computer upgrade costs. In 1998,
CalFarm sustained catastrophe losses before tax of $5.0 million in conjunction
with California wind and storm damage. The Other Property-Casualty Operations
underwriting results in 1999 and 1998 were also adversely impacted by losses in
the group health line of business because of higher health care costs and
increased utilization.

REAL ESTATE OPERATIONS

   Total revenues recognized in the Real Estate Operations in 2000, 1999 and
1998 were $84.5 million, $58.7 million and $37.7 million, respectively, and
pre-tax income was $5.5 million, $3.6 million and $1.4 million, respectively.
Revenues and operating income increased in 2000 compared to 1999 and in 1999
compared to 1998 due to an increase in the number of home sales (number of sales
were 469, 366 and 275 for the years ended December 31, 2000, 1999 and 1998,
respectively). Revenues also increased in 2000 compared to 1999 and in 1999
compared to 1998 because of an increase in the average selling price per home
(average selling price was $177,000, $158,000 and $137,000 for the years ended
December 31, 2000, 1999 and 1998, respectively). Land presently owned at a cost
of $34.5 million will support the construction of an estimated 1,300 homes over
the next several years. Changes in interest rates and 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

   At December 31, 2000 and 1999, Zenith's consolidated investment portfolio
emphasized high quality, taxable bonds and short-term investments, supplemented
by smaller portfolios of redeemable and other preferred and common stocks. Bonds
constituted 68% and 71%, and short-term investments constituted 19% and 20% of
the carrying value of Zenith's consolidated investment portfolio at
December 31, 2000 and 1999, respectively. Bonds with an investment grade rating
represented 94% and 95% of the consolidated carrying values of bonds at
December 31, 2000 and 1999, respectively. The average life of the consolidated
portfolio was 5.1 and 5.7 years at December 31, 2000 and 1999, respectively.

                                                                    TheZenith 31

   Zenith's investment portfolio decreased in the year ended December 31, 2000
principally to fund the use of cash in operations and the repurchases of
outstanding debt described in the Liquidity and Capital Resources section on
page 35.
   Zenith has identified certain securities, amounting to 96% of the investments
in debt securities at December 31, 2000 and 1999, as "available-for-sale."
Stockholders' equity increased by $9.6 million after deferred tax from
December 31, 1999 to December 31, 2000 and decreased by $25.7 million after
deferred tax from December 31, 1998 to December 31, 1999 as a result of changes
in the fair values of such investments. Stockholders' equity will fluctuate with
changes in the fair values of "available-for-sale" securities. The total fair
value of fixed maturity investments, including short-term investments, was
$753.8 million and $834.3 million at December 31, 2000 and 1999, repectively.
The unrealized gain (loss) on held-to-maturity and available-for-sale fixed
maturity investments were as follows:

   The yields on invested assets, which vary with the general level of interest
rates, the average life of invested assets and the amount of funds available for
investment, for the three years ended December 31, 2000 were as follows:



- ---------------------------------------------------
                       2000       1999       1998

- ---------------------------------------------------


   When, in the opinion of management, a decline in market value of investments
is considered to be "other than temporary," such investment is written down to
its net realizable value. The determination of "other than temporary" includes,
in addition to other relevant factors, a presumption that if the market value is
below cost by a significant amount for a period of time, a write down is
necessary. During the years ended December 31, 2000 and 1999, there were
$22.5 million and $1.7 million, respectively, of such write downs, including
$7.3 million during the fourth quarter of 2000.

   In December 2000, Zenith sold approximately 183 acres of land located in Las
Vegas, Nevada. The gain on the sale was $6.0 million, of which $5.1 million was
deferred at December 31, 2000.

PARENT

   Parent expenses in 2000 include $1.8 million before tax of severance costs
associated with the termination provisions of an employment contract of a
company officer.

MARKET RISK OF FINANCIAL INSTRUMENTS

   The fair value of the fixed maturity investment portfolio is exposed to
interest rate risk -- the risk of loss in fair value resulting from changes in
prevailing market rates of interest for similar financial instruments. However,
Zenith has the ability to hold fixed maturity investments to maturity. Zenith
relies on the experience and judgment of senior management to monitor and
mitigate the effects of market risk. Zenith does not utilize financial
instrument hedges or derivative financial instruments to manage risks, nor does
it enter into any swap, forward or options contracts, but will attempt to
mitigate its exposure through active portfolio management. 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. In addition, Zenith places the majority of its investments in
high quality, liquid securities and limits the amount of credit exposure to any
one issuer.

   The table below provides information about Zenith's financial instruments as
of December 31, 2000 for which fair values are subject to changes in interest
rates. For fixed maturity investments, the table presents fair value of
investments held and weighted average interest rates on such investments by
expected maturity dates. Such investments include redeemable preferred stock,
corporate bonds, municipal bonds, government bonds and mortgage-backed
securities. For debt obligations, the table presents principal cash flows by
expected maturity dates (including interest).

LIQUIDITY AND CAPITAL RESOURCES

   The P&C Operations generally create liquidity because insurance premiums are
collected prior to disbursements for claims and other policy benefits. Collected
premiums may be invested, principally in fixed maturity securities, prior to
their use in such disbursements, and investment income provides additional cash
receipts. Claim payments may take place many years after the collection of
premiums. In periods in which disbursements for claims and benefits, current
acquisition costs and current operating and other expenses exceed operating cash
receipts, cash flow is negative. Such negative cash flow is offset by cash flow
from investments, principally from short-term investments and maturities of
longer-term investments. The exact timing of the payment of claims and benefits
cannot be predicted with certainty. The P&C Operations maintain portfolios of
invested assets with varying maturities and a substantial amount of short-term
investments to provide adequate cash for the payment of claims. At December 31,
2000 and 1999, cash and short-term investments in the P&C Operations amounted to
$112.6 million and $92.1 million, respectively.

   In the year ended December 31, 2000, payment of income taxes for 1999,
including $56.0 million associated with the gain on sale of CalFarm, reduced
cash flow from operations. In the year ended December 31, 1999, $54.3 million of
cash was used to pay the balance of the purchase price for the RISCORP
Acquisition and net proceeds of approximately $211.0 million were received in
connection with the sale of CalFarm.

   Zenith National requires cash to pay any dividends declared to its
stockholders, make interest and principal payments on its outstanding debt
obligations and fund its operating expenses. Such cash requirements are
generally funded in the long run by dividends received from Zenith Insurance and
financing or refinancing activities by Zenith National. Investment income from
its investment portfolio also provides a current source of cash to Zenith
National.

   The P&C Operations are subject to insurance regulations which restrict their
ability to distribute dividends. Such dividend capabilities are set forth in
Note 17 to the Consolidated Financial Statements on page 62. Such restrictions
have not had, and under current regulations are not expected to have, a material
adverse impact on Zenith. The maximum dividend which can be paid to Zenith
National without prior approval of the California Department of Insurance in
2001 is $26.2 million. In 2000, Zenith National received $10.0 million of
dividend payments from Zenith Insurance. In 1999, Zenith National received
$130.0 million of such dividend payments, including a dividend of $100.0 million
paid from the gain on the sale of CalFarm and with the prior approval of the
California Department of Insurance. Zenith National has available cash,
short-term investments and other investments, which currently significantly
exceed its short-term cash requirements. Cash, short-term investments and other
investments in Zenith National amounted to $135.7 million and $171.7 million at
December 31, 2000 and 1999, respectively.

   At December 31, 2000, Zenith National had two revolving, unsecured lines of
credit in an aggregate amount of $70.0 million, all of which was available at
December 31, 2000. Under these agreements certain restrictive covenants apply
including the maintenance of certain financial ratios.

   The amount of capital in the P&C Operations is maintained relative to
standardized capital adequacy measures such as risk based capital where ratios
such as net premiums written to statutory surplus measure capital adequacy. Risk
based capital is used by regulators for regulatory financial surveillance
purposes and by rating agencies

34

to assign financial strength ratings to the P&C Operations and ratings for the
debt issued by Zenith National. From time to time, the level of capitalization
of the P&C Operations may be increased by contributions from Zenith National.
Zenith National made contributions of $25.0 million and $65.0 million in 2000
and 1998, respectively, to the capital and surplus of Zenith Insurance.

   In the first quarter of 2000, Zenith's financial strength and debt ratings
were reduced by Moody's Investors Service ("Moody's") and by Standard & Poor's
("S&P"), principally over concerns about continuing operating losses in the P&C
Operations. In August 2000, S&P affirmed its ratings of Zenith, but changed its
outlook for Zenith to "negative" and Moody's also changed its outlook for Zenith
to "negative" at the same time making no changes to Zenith's ratings. Both
rating agencies cited continuing concerns about the operating performance of the
P&C Operations. In the second quarter of 2000, A. M. Best Company reduced the
rating of the P&C Operations from A+ (Superior) to A (Excellent). The actions of
such rating agencies have had no material impact on Zenith's operations. Because
of the available invested assets and available lines of credit in Zenith
National, Zenith National has the flexibility, if necessary, to contribute
capital to the P&C Operations.

   From time to time, Zenith may make repurchases of its outstanding common
shares or outstanding debt. At December 31, 2000, Zenith National was authorized
to repurchase up to 938,000 shares of its common stock at prevailing market
prices pursuant to a share purchase program authorized by its Board of
Directors. These purchases are discretionary and can be adequately funded from
Zenith National's existing sources of liquidity. In 2000, Zenith National paid
$22.8 million to repurchase $16.5 million aggregate principal amount of the
outstanding 9% Senior Notes due 2002 and $8.0 million aggregate liquidation
amount of the outstanding 8.55% Capital Securities of the Zenith National
Insurance Capital Trust I, a Delaware statutory business trust, all of the
voting securities of which are owned by Zenith National (the "Trust"). The
repurchases resulted in an extraordinary gain before tax of $1.5 million. Zenith
National used its available cash balances to fund these purchases.

   The Real Estate Operations maintain certain bank credit facilities to provide
financing for development and construction of single-family residences for sale.
Each agreement pertains to a separate residential housing project. The
agreements provide that funding and repayment of development and construction
loans are made in tandem for each project. A development loan will always
precede a construction loan for a project and the proceeds of the construction
loan are required to first be used to pay off the respective development loan.
At December 31, 2000 and 1999, the maximum credit available was $29.7 million
and $37.1 million, respectively. At December 31, 2000 and 1999, $15.7 million
and $19.1 million, respectively, was outstanding under these facilities. Zenith
National also finances the land acquisitions of its Real Estate Operations
through inter-company loans.

   Insurance companies are required to have securities on deposit for the
protection of policyholders in accordance with various states' regulations. At
December 31, 2000 and 1999, investments carried at their fair value of
$235.9 million and $205.5 million, respectively, were on deposit to comply with
such regulations.

   On July 30, 1998, Zenith National issued $75.0 million of 8.55% Capital
Securities at a price of $996.24 per security through the Trust. (See Note 10 to
the Consolidated Financial Statements on pages 56-57 for a full description of
the Capital Securities).

                                                                    TheZenith 35

CODIFICATION OF STATUTORY ACCOUNTING PRINCIPLES

   In 1998, the National Association of Insurance Commissioners ("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 for insurance
companies 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 established January 1, 2001 as the effective
date of the Codification and the California and Texas Departments of Insurance
have adopted the Codification. Zenith believes that the Codification, as
currently constituted, will not have a material impact on the statutory capital
and surplus of the P&C Operations.

RECENTLY ISSUED ACCOUNTING STANDARDS

   On June 15, 1998, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 133 ("SFAS No. 133") "Accounting
for Derivative Instruments and Hedging Activities". SFAS No. 133 is effective
for all fiscal years beginning after June 15, 2000. SFAS No. 133 requires, among
other things, that companies record all derivative instruments on the balance
sheet at fair value. Changes in the fair value of derivatives will be required
to be recorded each period in current earnings or other comprehensive income,
depending on the nature of the derivative. Zenith believes that adoption of SFAS
No. 133 will not have a material effect on its results of operations or its
financial position.

   The analysis above presents the development of Zenith National Insurance
Corp. and subsidiaries' balance sheet liabilities for 1990 through 2000. The
first line in the table shows the liability for unpaid loss and loss adjustment
expense, net of reinsurance, as estimated at the end of each calendar year. The
first section shows the actual payments of loss and loss adjustment expenses
that relate to each year-end liability as they were paid during subsequent
annual periods. The second section shows revised estimates of the original
unpaid amounts, net of reinsurance, including the subsequent payments. The next
line shows the favorable or deficient developments of the original estimates for
each year, net of reinsurance. This loss reserve development table is cumulative
and, therefore, ending balances should not be added since the amount at the end
of each calendar year includes activity for both the current and prior years.
The liability at the end of each year includes an estimate of the amount yet
unpaid and still due at the subsequent re-evaluation date for all previously
estimated liabilities. For example, the liability at the end of 1997 includes an
estimate of the amount still due on the 1996 and prior liabilities. Information
for 1998 includes the results of the acquisition of substantially all assets and
certain liabilities from RISCORP, Inc. and subsidiaries (See Note 14 to the
Consolidated Financial Statements on pages 58-59). The data prior to 1999 has
been restated to exclude the results of CalFarm Insurance Company, which was
sold effective March 31, 1999 (See Note 13 to the Consolidated Financial
Statements on pages 57-58).
Since conditions and trends that have affected loss and loss adjustment expense
development in the past may not occur in the future in exactly the same manner,
if at all, future results may not be reliably predicted by extrapolation of the
data presented.
   Adverse development in 2000 on the reserves established at December 31, 1999
is attributable, principally, to additional estimates of 1999 catastrophe
losses. Adverse development in 1999 on the reserves established at December 31,
1998 is attributable, principally, to an increase in the reserves acquired from
RISCORP (see Note 14 to the Consolidated Financial Statements on pages 58-59).

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
ZENITH NATIONAL INSURANCE CORP. AND SUBSIDIARIES

NOTE 1

SUMMARY OF ACCOUNTING POLICIES, OPERATIONS AND PRINCIPLES OF CONSOLIDATION

   Zenith National Insurance Corp. ("Zenith National") is engaged through its
wholly-owned property-casualty insurance subsidiaries (the "P&C Operations") in
Workers' Compensation insurance; Reinsurance, principally of world-wide, assumed
reinsurance of property losses from catastrophes and large property risks; and
Other Property-Casualty insurance, consisting of automobile, farmowners,
commercial coverages, group health and homeowners coverage, primarily in
California, operated by CalFarm Insurance Company ("CalFarm"), which was sold
effective March 31, 1999 by Zenith Insurance Company ("Zenith Insurance"), a
wholly owned subsidiary of Zenith National. The P&C Operations sell insurance
and reinsurance through agents and brokers and not directly to consumers. The
Real Estate Operations develop land and primarily construct single-family
residences in Las Vegas, Nevada. Investment operations provide income and
realized gains on investments, primarily from debt securities. The Parent
operations represent Zenith National, a holding company which owns, directly or
indirectly, all of the capital stock of the P&C Operations, non-insurance
companies and securities.

   The financial statements have been prepared in accordance with generally
accepted accounting principles ("GAAP") in the United States and include Zenith
National and its subsidiaries (collectively, "Zenith"). GAAP requires the use of
assumptions and estimates in reporting certain assets and liabilities and
related disclosures and actual results could differ from those estimates. All
significant intercompany transactions and balances have been eliminated in
consolidation.

   The comparability of the results of operations between each of the three
years ended December 31, 2000, 1999, 1998 is affected by several items. First,
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"-- see Note 14). Second, in the third quarter of 1999,
Zenith recorded net charges of $50.0 million before tax ($32.5 million after tax
or $1.89 per share) associated with an increase in the estimated net liabilities
for unpaid losses and loss adjustment expenses acquired from RISCORP (the
"RISCORP Purchase Adjustment"-- see Note 14). Third, effective March 31, 1999,
Zenith sold CalFarm which had previously operated Zenith's Other
Property-Casualty Operations (see Note 13). The sale of CalFarm resulted in a
gain of $104.3 million after tax.

Investments

   Zenith's investments in debt and equity securities are identified in three
categories as follows: held-to-maturity -- those securities, which by their
terms must be redeemed by the issuing company and that Zenith has the positive
intent and ability to hold to maturity, and are reported at amortized cost;
trading -- those securities that are held principally for the purpose of selling
in the near term and are reported at fair value with unrealized gains and losses
included in earnings; and available-for-sale -- those securities not classified
as either held-to-maturity or trading and are reported at fair value with
unrealized gains and losses excluded from earnings and reported as a separate
component of stockholders' equity, net of deferred tax. Other investments are
carried at cost.

48

   Short-term investments include debt securities such as corporate, municipal
and treasury securities with maturities of less than one year at the time of
purchase. For these short-term investments, the amortized cost is a reasonable
estimate of fair value. Investment income is recorded when earned. Realized
capital gains and losses are calculated based on the cost of securities sold,
which is determined by the "identified cost" method.

Cash

   Cash includes currency on hand and demand deposits with financial
institutions.

Recognition of Property-Casualty
Revenue and Expense

   Premiums are earned on a pro rata basis over the terms of the policies.
Premiums applicable to the unexpired terms of policies in force are recorded as
unearned premiums. Included with premiums earned is an estimate for earned but
unbilled audit premiums. Workers' Compensation premiums are determined based
upon the payroll of the insured and applicable premium rates and are recorded as
written when billed. Premiums for retrospectively-rated policies are also
determined by the loss experience incurred by the policyholder.

   Policy acquisition costs, consisting of commissions, premium taxes and
certain other underwriting costs, are deferred and amortized as the related
premiums are earned.

   The P&C Operations make provisions for the settlement of all incurred claims,
both reported and unreported. The liabilities for unpaid loss and loss
adjustment expenses are estimates of the eventual costs of claims incurred but
not settled, less estimates of salvage and subrogation. Estimates for reported
claims are primarily determined by evaluation of individual reported claims and
amounts reported by ceding companies. Estimates for claims incurred but not
reported are based on experience with respect to the probable number and nature
of such claims. The methods for making such estimates and for establishing the
resulting liabilities are continually reviewed and updated and any adjustments
resulting therefrom are reflected in earnings currently. Estimates of losses
from environmental and asbestos-related claims are included in overall loss
reserves and to date have not been material. Due to the significant
uncertainties inherent in establishing such reserves, the ultimate exposure may
vary from the amounts currently reserved.

   An estimated provision for Workers' Compensation policyholders' dividends is
accrued as the related premiums are earned. Such dividends do not become a fixed
liability unless and until declared by the respective Boards of Directors of
Zenith's insurance subsidiaries. Zenith's policyholder dividends have not been
material in the three years ended December 31, 2000 due to competitive
conditions in the workers' compensation industry.

   Property insurance and reinsurance coverages expose Zenith to the risk of
significant loss in the event of major adverse natural phenomena, known in the
insurance industry as catastrophes. Catastrophes may cause significant
contemporaneous financial statement losses since catastrophe losses may not be
accrued in advance of the event.

   Approximately 45.7% and 28.2% of the premiums earned in the Workers'
Compensation Operations in 2000 was in California and Florida, respectively. The
concentration of Zenith's business in these states makes the results of
operations highly dependent upon the states' economies, social and cultural
trends, legislative and regulatory changes, and catastrophic events such as
windstorms and earthquakes.

                                                                    TheZenith 49

Reinsurance

   In accordance with general industry practices, the P&C Operations annually
purchase, principally from large United States reinsurance companies, excess of
loss reinsurance to protect Zenith against the impact of large, irregularly
occurring losses. Such reinsurance reduces the magnitude of sudden and
unpredictable changes in net income and the capitalization of the P&C
Operations. 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.
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. Historically, no material amounts due from reinsurers have been
written off as uncollectable. At December 31, 2000, Reliance Insurance Company
("Reliance") owed Zenith Insurance approximately $6.3 million in reinsurance
recoverables for paid and unpaid losses in connection with reinsurance
arrangements assumed by Zenith Insurance in the 1996 acquisition of the
Associated General Contractors Self-Insurance Fund. On January 29, 2001,
Reliance entered into an Order of Supervision with the Pennsylvania Insurance
Department under which its business and operations will be monitored and
reviewed by the Department. Zenith Insurance considered its receivables from
Reliance in the normal course of assessing the collectibility of reinsurance
recoverables. Zenith Insurance believes this matter will not have a material
adverse effect on its financial condition or results of operations.

   Earned premiums and loss and loss adjustment expenses incurred are stated in
the Consolidated Statement of Operations after deduction of amounts ceded to
reinsurers. Balances due from reinsurers on unpaid losses, including an estimate
of such recoverables related to reserves for incurred but not reported losses,
are reported as assets and are included in receivable from reinsurers even
though amounts due on unpaid losses are not recoverable from the reinsurer until
such losses are paid. Receivable from reinsurers on unpaid losses amounted to
$264.6 million and $292.8 million at December 31, 2000 and 1999, respectively,
of which approximately $185.4 million and $216.2 million, respectively, were
reinsurance recoverables relating to reinsurance arrangements entered into by
RISCORP. Such RISCORP-related amounts are primarily recoverable from large
United States reinsurance companies. Also included in reinsurance recoverable on
unpaid losses is $50.0 million of reinsurance recoverable under reinsurance
entered into by Zenith Insurance in connection with the RISCORP Acquisition (see
Note 14). Such reinsurance recoverable is secured by a trust account and an
irrevocable letter of credit.

Real Estate Operations

   Land, land development costs and construction costs, including costs of
acquisition and development, property taxes and related interest, are
capitalized. Such costs, and an estimate of the costs to complete a project, are
recognized pro rata against sales of completed units (see Note 9). Such
capitalized costs are included in other assets. The profitability of the Real
Estate Operations is dependent upon real estate values, interest rates,
construction costs, competition and management ability.

   Included in other assets is land and real estate construction in progress
carried at a cost of $61.1 million and $87.9 million at December 31, 2000 and
1999, respectively.

50

Properties and Equipment

   Properties and equipment are stated at cost less accumulated depreciation.
Depreciation is calculated principally on a straight-line basis using the
following useful lives: buildings, 10 to 40 years; and furniture, fixtures and
equipment, 3 to 10 years.

   Expenditures for maintenance and repairs are charged to operations as
incurred. Additions and improvements to buildings and other fixed assets are
capitalized and depreciated over the useful lives of the properties and
equipment. Upon disposition, the asset cost and related depreciation are removed
from the accounts and the resulting gain or loss is included in income.

Intangible Assets

   Intangible assets include the costs in excess of tangible assets acquired,
including those related to the RISCORP Acquisition discussed in Note 14. The
amounts assigned to assets acquired since 1970 are being amortized on a
straight-line basis over 25 years. Amortization expense was $0.8 million,
$0.9 million and $1.1 million in 2000, 1999 and 1998, respectively. Accumulated
amortization was $2.7 million and $1.9 million at December 31, 2000 and 1999,
respectively. Of the intangible assets at December 31, 2000 and 1999, $20.4
million and $21.2 million, respectively, were amortizable. Management
periodically assesses the recoverability of these intangible assets based on a
review of projected, undiscounted cash flows of the operations acquired.

Codification of Statutory
Accounting Principles

   In 1998, the National Association of Insurance Commissioners ("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 for insurance
companies 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 established January 1, 2001 as the effective
date of the Codification and the California and Texas Departments of Insurance
have adopted the Codification. Zenith believes that the Codification, as
currently constituted, will not have a material impact on the statutory capital
and surplus of the P&C Operations.

Recently Issued Accounting Standards

   On June 15, 1998, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 133 ("SFAS No. 133") "Accounting
for Derivative Instruments and Hedging Activities". SFAS No. 133 is effective
for all fiscal years beginning after June 15, 2000. SFAS No. 133 requires, among
other things, that companies record all derivative instruments on the balance
sheet at fair value. Changes in the fair value of derivatives will be required
to be recorded each period in current earnings or other comprehensive income,
depending on the nature of the derivative. Zenith believes that adoption of SFAS
No. 133 will not have a material effect on its results of operations or its
financial position.

                                                                    TheZenith 51

   Fluctuating interest rates will impact stockholders' equity, profitability
and maturities of certain debt and preferred securities. Expected maturities may
differ from contractual maturities because borrowers may have the right to call
or prepay obligations with or without call or prepayment penalties.
Mortgage-backed securities are shown as being due at their average expected
maturity dates. Redeemable preferred stocks with sinking fund redemption periods
are shown as being due at the mid-point of the sinking fund period.

   When, in the opinion of management, a decline in market value of an
investment is considered to be "other than temporary," such investment is
written down to its net realizable value. The determination of "other than
temporary" includes, in addition to other relevant factors, a presumption that
if the market value is below cost by a significant amount for a period of time,
a write down is necessary. Such write downs are reflected as a reduction of net
realized gains on investments. During the years ended December 31, 2000 and
1999, there were $22.5 million and $1.7 million, respectively, of such write
downs.

   The gross realized gains on sales of investments classified as
available-for-sale during 2000, 1999 and 1998 were $8.7 million, $8.2 million
and $9.9 million, respectively, and the gross realized losses were
$2.4 million, $5.5 million and $3.0 million, respectively. The change in net
unrealized holding (losses) gains on trading securities, which is included in
realized gains, was $10,000, $(96,000) and $54,000 for the years ended December
31, 2000, 1999 and 1998, respectively.

   At December 31, 2000 and 1999, 96% of Zenith's consolidated portfolio of
fixed maturity investments were classified as available-for-sale with the
unrealized appreciation or depreciation recorded as a separate component of
stockholders' equity. The change in fair value of fixed maturity investments
classified as available-for-sale resulted in an increase in stockholders' equity
of $9.6 million after deferred tax from December 31, 1999 to December 31, 2000,
compared to a decrease of $25.7 million from 1998 to 1999.

   Realized and unrealized investment gains and losses on fixed maturity
investments and equity securities are summarized as follows:

FAIR VALUES OF FINANCIAL INSTRUMENTS

   Financial instruments are contractual obligations that result in the delivery
of cash or an ownership interest in an entity. Disclosures regarding the fair
value of financial instruments have been derived using external market sources
or estimates using present value and other valuation techniques.

   The following summarizes the carrying amounts and fair value of Zenith's
financial instruments. For financial instruments not discussed below, the
carrying amount is a reasonable estimate of the fair value.

   Zenith's net deferred tax asset is expected to be fully recoverable because
all future deductible amounts can be offset by reversing deferred tax
liabilities, recovery of federal income taxes paid within the statutory
carryback period or anticipated future taxable income, including investment
income. Property-casualty loss reserves are not discounted for book purposes,
however the Tax Reform Act of 1986 requires property and casualty loss reserves
to be discounted for tax purposes.

   Zenith files a consolidated federal income tax return. The P&C Operations pay
premium taxes on gross premiums written in lieu of most state income or
franchise taxes.

PAYABLE TO BANKS

   At December 31, 2000, Zenith National had two revolving, unsecured lines of
credit in an aggregate amount of $70.0 million, all of which was available at
December 31, 2000. Under these agreements, certain restrictive covenants apply
including the maintenance of certain financial ratios.

   The Real Estate Operations maintain certain bank credit facilities to provide
financing for development and construction of single-family residences for sale.
At December 31, 2000, these loans bear interest at the rates of prime plus 0.75%
or prime plus 1.0% and mature between June 2001 and April

                                                                    TheZenith 55

2002. Each agreement pertains to a separate residential housing project and the
maximum credit available was $29.7 million and $27.1 million at December 31,
2000 and 1999, respectively. The agreements provide that funding and repayment
of development and construction loans are made in tandem for each project. A
development loan will always precede a construction loan for a project and the
proceeds of the construction loan are required to first be used to pay off the
respective development loan. At December 31, 2000 and 1999, $15.7 million and
$19.1 million, respectively, was outstanding under these facilities.

   Zenith National also finances the land acquisitions of its Real Estate
Operations through inter-company loans.
NOTE 8
SENIOR NOTES PAYABLE

   Zenith National had $58.5 million and $75.0 million of the $75.0 million
issued of its 9% Senior Notes due 2002 (the "9% Notes") at December 31, 2000 and
1999, respectively (see Note 11). 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 the years ended December 31, 2000, 1999 and 1998, $5.8 million,
$6.9 million and $6.9 million, respectively, of interest and issue costs were
expended. Covenants contained in the indenture include restrictions on the
ability of Zenith National to incur secured debt and the right of holders of the
9% Notes to require Zenith National to repurchase the 9% Notes upon a decline in
the rating of the 9% Notes within ninety days after the occurrence of certain
events. Those events are: (a) a person or group becomes the beneficial owner of
more than 50% of Zenith National common stock; (b) 10% or more of Zenith
National common stock is acquired by Zenith National within any 12-month period;
or (c) the sum of the fair market value of distributions (other than regular
dividends or distributions of capital stock) and the consideration for purchases
of Zenith National common stock by Zenith National during a 12-month period is
30% or more of the fair market value of outstanding Zenith National common
stock.

NOTE 10

REDEEMABLE SECURITIES

   On July 30, 1998, Zenith issued $75.0 million of 8.55% Capital Securities at
a price of $996.24 per security through Zenith National Insurance Capital Trust
I, a Delaware statutory business trust (the "Trust"), all of the voting
securities of which are owned by Zenith National. Each Capital Security pays
semi-annual cumulative cash distributions at the annual rate of 8.55% of the
$1,000 liquidation amount per security.

   The Trust used the proceeds from its offering to purchase $75.0 million of
Zenith National's 8.55% Subordinated Deferrable Interest Debentures due 2028
(the "Subordinated Debentures"), which constitute the principal asset of 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

56

are redeemable at any time by Zenith National at the then present value of the
remaining scheduled payments of principal and interest. Payments on the Capital
Securities, including distributions and redemptions, follow those of the
Subordinated Debentures. Zenith National used $65.0 million from the net
proceeds to make a capital contribution to Zenith Insurance. The remaining net
proceeds were used for general corporate purposes. Zenith National fully and
unconditionally guaranteed the distributions on, and the liquidation amount
generally of, the Capital Securities to the extent the Trust has funds legally
available therefor. Zenith National's guarantee of the Capital Securities, as
well as the Subordinated Debentures, are subordinated to all other indebtedness
of Zenith National. At December 31, 2000 and 1999, $67.0 million and
$75.0 million, respectively, was outstanding (see Note 11).

   The issue cost and discount on the Subordinated Debentures of $1.7 million
are being amortized over the term of the Subordinated Debentures. During the
years ended December 31, 2000, 1999 and 1998, $5.9 million, $6.5 million and
$2.7 million, respectively, of interest, issue costs and discount were expensed.

NOTE 11

EXTRAORDINARY ITEM--GAIN ON EXTINGUISHMENT OF DEBT

   In 2000, Zenith National paid $22.8 million to repurchase $16.5 million
aggregate principal amount of the outstanding 9% Notes and $8.0 million
aggregate liquidation amount of the outstanding 8.55% Capital Securities. The
repurchases resulted in an extraordinary gain before tax of $1.5 million. Zenith
National used its available cash balances to fund these purchases.

SALE OF CALFARM INSURANCE COMPANY

   Effective March 31, 1999, Zenith Insurance completed the sale of CalFarm for
$273.0 million in cash to Nationwide Mutual Insurance Company. CalFarm wrote
Zenith's Other Property-Casualty business, principally in California. 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.

RISCORP ACQUISITION AND THE RISCORP PURCHASE ADJUSTMENT

   On April 1, 1998, pursuant to an Asset Purchase Agreement dated June 17, 1997
(as amended from time to time, the "Asset Purchase Agreement") between Zenith
Insurance and RISCORP, 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 GAAP 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. Zenith Insurance recorded the assets and
liabilities acquired from RISCORP at their estimated fair values consistent with
the values determined by the Neutral Auditor and Neutral Actuary. Zenith
Insurance indicated that any new information that might become available with
respect to certain assets and liabilities acquired from RISCORP may change the
estimates of the carrying values of such amounts and such changes, if any, would
be reflected in the results of operations for the period in which they occur.

   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,
the RISCORP Purchase Adjustment, which mainly comprises an increase of
$46.0 million before tax ($29.9 million after tax) in the estimated net
liabilities for unpaid losses and loss adjustment expenses acquired from
RISCORP. The increase resulted primarily from 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 net ($12.4 million after tax) as a result of such
increase in net liabilities. Zenith Insurance purchased reinsurance protection
relating to adverse development of the unpaid loss and loss adjustment expense
reserves acquired from RISCORP. Such reinsurance allows Zenith Insurance to
recover up to $50.0 million in excess of $182.0 million for net unpaid losses
and allocated loss adjustment expenses acquired from RISCORP. In the third
quarter of 1999, Zenith Insurance recorded an increase in the amount recoverable
to $50.0

58

million and a benefit of $9.0 million ($5.9 million after tax) associated with
such reinsurance.

   The RISCORP Purchase Adjustment, net of the benefit of reinsurance protection
and the recovery of $6.0 million pursuant to the "settlement agreement" (see
"RISCORP Litigation" in Note 15), in the aggregate, reduced income by
$50.0 million ($32.5 million after tax, or $1.89 per share) in 1999.

   The remaining deferred benefit associated with the reinsurance relating to
the RISCORP reserves before tax was $14.7 million and $23.0 million at
December 31, 2000 and 1999, respectively.

$5.7 million and $5.8 million, respectively.

   Other than the RISCORP litigation described below, 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.

RISCORP Litigation
   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 agreed, among other things,
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. Zenith
Insurance and RISCORP also agreed that Zenith Insurance would receive
$6.0 million from an escrow account established pursuant to the Asset Purchase
Agreement, and RISCORP would receive the balance of the escrow account. 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
informed Zenith Insurance and RISCORP that it would not consider the issue
raised by RISCORP because the issue had not previously been raised as a dispute
pursuant to the procedures set forth in the 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. On October 9, 2000, RISCORP filed a First Amended Complaint in the
Superior Court of

                                                                    TheZenith 59

Fulton County. RISCORP's First Amended Complaint alleges causes of action for
breach of contract against the Neutral Auditor and Neutral Actuary and, in
conjunction, seeks a declaration that could have the effect of requiring Zenith
to pay either $18.1 million (and related charges) or $5.9 million. RISCORP also
has asserted causes of action for professional negligence solely against the
Neutral Auditor and Neutral Actuary in which it seeks damages of either
$18.1 million (and related charges) or $5.9 million. Zenith is unable to predict
the outcome of this litigation.

Contingencies Surrounding Recoverability of Special Disability Trust Fund
Receivable

   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 Insurance 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, 2000
and 1999, the receivable from the Fund was $31.1 million and $37.0 million,
respectively, related to the pre-January 1, 1998 claims.
NOTE 16

COMMON STOCK
   Under employee non-qualified stock option plans adopted by the Board of
Directors and Stockholders of Zenith National in 1978 and in 1996, options are
granted to certain officers and key employees for the purchase of Zenith
National's common stock at 100% of the market price at the date of grant. The
majority of the options outstanding at December 31, 2000 and 1999 expire five
years after the date of the grant or three months after termination of
employment and vest one-fourth per year after the first year. One grant for
1,000,000 shares is for a term of ten years and vests one-fifth per year after
the first year.

   Zenith has adopted the disclosure-only provisions of Statement of Financial
Accounting Standards No. 123 ("SFAS No. 123") "Accounting for Stock-Based
Compensation." Accordingly, no compensation cost has been recognized for the
stock option plans. Had compensation cost for Zenith's stock option plans been
determined based on the fair value at the grant date for awards in 2000, 1999
and 1998 consistent with the provisions of SFAS No. 123, Zenith's net (loss)
income and per share amounts would have been reduced to the pro-forma amounts
indicated as follows:

   From time to time, Zenith may make repurchases of its outstanding common
shares or outstanding debt. At December 31, 2000, Zenith National was authorized
to repurchase up to 938,000 shares of its common stock at prevailing market
prices pursuant to a share purchase program authorized by its Board of
Directors. These purchases are discretionary and can be adequately funded from
Zenith National's existing sources of liquidity.

                                                                    TheZenith 61

NOTE 17

DIVIDEND RESTRICTIONS

   The California and Texas Insurance Holding Company System Regulatory Acts
limit the ability of Zenith Insurance to pay dividends to Zenith National, and
of the insurance subsidiaries of Zenith Insurance to pay dividends to Zenith
Insurance, by providing that the appropriate insurance regulatory authorities in
the states of California and Texas must approve any dividend that, together with
all other such dividends paid during the preceding twelve months, exceeds the
greater of: (a) 10% of the paying company's statutory surplus as regards
policyholders at the preceding December 31; or (b) 100% of the net income for
the preceding year. In addition, any such dividend must be paid from
policyholders' surplus attributable to accumulated earnings. During 2000, Zenith
Insurance paid $10.0 million of dividends to Zenith National. 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.
Stockholder's equity of the P&C Operations, in accordance with GAAP, amounted to
$315.0 million as of December 31, 2000, of which $26.2 million can be paid in
2001 to Zenith National in dividends without prior approval.

   The insurance business is subject to state-by-state regulation and
legislation focused on solvency, pricing, market conduct, claims practices,
underwriting, accounting, investment criteria and other areas. Such regulation
and legislation is constantly changing and compliance is essential and is an
inherent risk of the business.

common stock at an average price of $27.64 and $24.90 per share, respectively,
were outstanding as of December 31, 2000 and 1999 but were not included in the
computation of diluted earnings per share because the options' exercise prices
were greater than the average market price of the common shares, and, therefore,
the effect would be anti-dilutive.

SEGMENT INFORMATION

   Zenith classifies its business into the following segments: Workers'
Compensation, Reinsurance, Other Property-Casualty (through March 31, 1999, the
date of the sale of CalFarm), Real Estate, Investment and Parent. Segments are
designated based on the types of products and services provided. 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. Reinsurance principally consists of world-wide, assumed
reinsurance of property losses from catastrophes and large property risks. Other
Property-Casualty, which was operated by CalFarm and was sold effective
March 31, 1999, represented multiple product line direct insurance other than
workers' compensation primarily in California. The Real Estate Operations
develop land and primarily construct single-family residences in Las Vegas,
Nevada. Investment operations provide income and realized gains on investments,
primarily from debt securities. The Parent operations represent Zenith National,
a holding company which owns, directly or indirectly, all of the capital stock
of the P&C Operations, non-insurance companies and securities.
   The accounting policies of the segments are the same as those described in
Note 1. Zenith evaluates insurance segment performance based on the combined
ratios and income or loss from operations before income tax, and not including
investment income or realized gains or losses.

Information as to the operations of the segments is set forth below:

   REPORT OF INDEPENDENT ACCOUNTANTS

To the Stockholders and Board of Directors of
Zenith National Insurance Corp.:

   In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of operations, cash flows, and stockholders' equity
present fairly, in all material respects, the financial position of Zenith
National Insurance Corp. and subsidiaries (the "Company") at December 31, 2000
and 1999, and the results of their operations and their cash flows for each of
the three years in the period ended December 31, 2000, in conformity with
accounting principles generally accepted in the United States of America. These
financial statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these statements in accordance with
auditing standards generally accepted in the United States of America, which
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.
