These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with generally accepted auditing standards. Those standards 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. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of The Zenith Investment Partnership 401(k) Plan as of December 31, 1993 and 1992 and the changes in net assets available for benefits for the years then ended in conformity with generally accepted accounting principles. Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedules of the Plan, listed in the index on page 1, are presented for purposes of additional analysis and are not a required part of the basic financial statements, but are supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. The supplemental schedules have been subjected to the auditing procedures applied in the audit of the basic financial statements and, in our opinion are fairly stated in all material respects, in relation to the basic financial statements taken as a whole.

THE PLAN: The following is a general description of The Zenith Investment Partnership 401(k) Plan (the "Plan"). GENERAL The Plan is a qualified stock bonus plan offered to all eligible employees of Zenith National Insurance Corp. ("ZNIC") and its affiliates ("the Company"), who are age twenty-one or older as of the enrollment dates. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 ("ERISA") and Section 401(a) and Section 401(k) of the Internal Revenue Code of 1986, as amended ("IRC"). At December 31, 1993 and December 31, 1992 there were, respectively, 1,004 and 863 participants in the Plan. Of those participants, 825 and 726 in 1993 and 628 and 471 in 1992 elected to invest, either wholly or partially, in the Short-Term Investment Fund and Company Stock Fund, respectively. CONTRIBUTIONS Participants may elect to contribute between 1% to 12% of their basic compensation up to a maximum of $8,994 for 1993 and $8,728 for 1992 (Salary Reduction Contributions). The maximum is adjusted each year for increases in the cost of living as provided in applicable regulations. This annual amount is an aggregate limitation that applies to all of an individual's Salary Reduction Contributions and similar contributions under other plans. The Company contributes 33-1/3% of the participant's "matched" contribution amount (matched contributions are defined as the first 6% of each participant's monthly contributions). The Company's contribution is invested exclusively in the common stock of ZNIC ("Company Stock"). 5 THE ZENITH INVESTMENT PARTNERSHIP 401(k) PLAN NOTES TO FINANCIAL STATEMENTS, CONTINUED ________________ 1. THE PLAN, CONTINUED: The Salary Reduction Contributions, made on behalf of each participant, are paid to the Trustee on or immediately after the last day of each month, and are subsequently deposited to the investment funds as directed by the participant. PARTICIPANT ACCOUNTS Each participant's account is credited with: (1) the participant's contributions, (2) participant rollover contributions from non-Company plans, (3) the related Company matching contributions, and (4) fund earnings. These accounts are summarized in the accompanying financial statements as net assets available for benefits. VESTING Each participant has an immediate, fully vested right to receive all Salary Reduction Contributions, all Company matching contributions made prior to January 1, 1991, and earnings thereon, upon termination from the Company, or upon separation caused by death of the participant. All Company matching contributions made after January 1, 1991 are subject to a five year graduated vesting schedule with respect to participants who became employed by the Company on or after April 1, 1988. However, irrespective of the vesting schedule, a participant is fully vested upon his death, disability or attainment of Normal Retirement Age. WITHDRAWALS PRIOR TO TERMINATION OF EMPLOYMENT Except in limited circumstances, withdrawals may not be made by a participant while employed by the Company. Hardship withdrawals of a participant's Salary Reduction Contributions are permitted where a participant has an immediate and heavy financial need 6 THE ZENITH INVESTMENT PARTNERSHIP 401(k) PLAN NOTES TO FINANCIAL STATEMENTS, CONTINUED __________________ 1. THE PLAN, CONTINUED: (as determined under Section 401(k)(2)(B)(IV) of the IRC) and that need cannot be satisfied from other resources of the participant. In addition, any participant who is 59-1/2 years old may only withdraw his Salary Reduction Contributions. INVESTMENTS Each participant directs that Salary Reduction Contributions for his benefit and any earnings thereon be invested in one or both of the following funds: a. A Short-Term Investment Fund which invests in a no-load diversified open-end management investment company whose objective is maximum current income consistent with liquidity and the maintenance of a portfolio of high quality, short-term "money-market" instruments; or b. A Company Stock Fund which invests solely in Company stock. The Company's contributions and any earnings thereon will be invested in the Company Stock Fund and are not subject to participant direction until such participant reaches age fifty-five (55). PAYMENT OF BENEFITS Upon termination of employment, if a distribution is made, a participant (1) receives cash with respect to his interest in the Short-Term Investment Fund and (2) may elect to receive cash or shares of Company Stock plus cash in lieu of any fractional shares, with respect to his interest in the Company Stock Fund. EXPENSES Expenses in connection with the purchase or sale of stock or other securities are charged to the fund for which such purchase or sale is made. The Trust Agreement stipulates that expenses incurred by the Trustee in the performance 7 THE ZENITH INVESTMENT PARTNERSHIP 401(k) PLAN NOTES TO FINANCIAL STATEMENTS, CONTINUED __________________ 1. THE PLAN, CONTINUED: of its duties shall be paid from the Trust Fund unless paid by the Company at its sole discretion. During 1993 and 1992, the Company elected to pay the Trustee's expenses in excess of the interest earned during the year on temporary invested cash. The total Trustee expenses for 1993 and 1992 were $24,197 and $18,523, of which $959 and $1,136 respectively, were offset by income on unallocated cash temporarily invested. The balances of $23,238 and $17,387 were paid by the Company. In addition, certain administrative expenses such as accounting, legal and recordkeeping fees, were paid by the Company during 1993 and 1992. TERMINATION While the Company has not expressed an intent to terminate the Plan, it may do so at any time. Upon such termination, each participant shall be fully (100%) vested in his account balances, determined as of the date of such termination. ADMINISTRATION The Plan is administered by an Administrative Committee appointed by the Board of Directors of ZNIC. The Committee has responsibility for administration of the Plan, including supervision of the collection of contributions, delivery of such contributions to the trustee, and maintenance of necessary records. The Trustee is City National Bank, Beverly Hills, California. The Trustee's responsibilities include receipt of Plan contributions, investment and maintenance of trust assets in the available funds, and distributions under the Plan of such amounts as the Committee shall direct from time to time. RECLASSIFICATIONS Certain amounts in the 1992 financial statements have been reclassified to conform to the 1993 presentation. 8 THE ZENITH INVESTMENT PARTNERSHIP 401(k) PLAN NOTES TO FINANCIAL STATEMENTS, CONTINUED ___________________ 1. THE PLAN, CONTINUED: PLAN AMENDMENTS A plan amendment was adopted by the Board of Directors of ZNIC on March 17, 1994 with an effective date of March 31, 1994. The amendment provides that after March 31, 1994 no future additions to any Participant Matched Contributions or Unmatched Contributions Account are to be invested in Company Stock, except that dividends on shares of Company Stock comprising March 31, 1994 balances shall continue to be added to such accounts. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: INVESTMENTS Investments are stated at fair value. The value ("net asset value") of a share of the no-load diversified open- end management investment company ("Management Company") in which the Short-Term Investment Fund invests is determined by adding the value of all securities and other assets in the Management Company's portfolio, deducting the Management Company's liabilities and dividing by the number of shares outstanding. The Management Company intends to use its best efforts to maintain a constant net asset value of $1 per share. The value of the Company Stock is determined using the December 31, 1993 and 1992 closing price on the New York Stock Exchange. Purchases and sales of securities are reflected on a trade date basis (the date when the order to buy or sell is executed). Gains or losses on sales of securities are computed on an average cost basis. Dividend income is accrued on the ex-dividend date. The net appreciation (depreciation) in the fair value of the Plan's investments disclosed in the Statement of Changes in Net Assets Available For Benefits consists of realized gains or losses and unrealized appreciation (depreciation) on investments. 9 THE ZENITH INVESTMENT PARTNERSHIP 401(k) PLAN NOTES TO FINANCIAL STATEMENTS, CONTINUED _________________ 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED: CONTRIBUTIONS Company and participant contributions are recorded in the period that a participant's payroll deduction is made. 3. TAX STATUS: The Plan was designed to qualify under Sections 401(a) and 401(k) of the IRC such that the Trust is exempt from federal income taxes under Section 501(a) of the IRC. The Plan has received a favorable determination letter from the Internal Revenue Service as to the above. 4. NET ASSET ALLOCATION: As of December 31, 1993 net assets available for plan benefits of the Company Stock Fund and Short-Term Investment Fund were $6,840,593 and $5,652,808, respectively, and as of December 31, 1992 were $5,007,424 and $4,237,307, respectively. 5. FEDERAL INCOME TAXES APPLICABLE TO PARTICIPANTS: The income tax rules affecting Plan participation are complex, subject to interpretation by the Secretary of the Treasury and subject to change. A general summary of the Federal tax consequences of participation in the Plan 10 THE ZENITH INVESTMENT PARTNERSHIP 401(k) PLAN NOTES TO FINANCIAL STATEMENTS, CONTINUED ___________________ 5. FEDERAL INCOME TAXES, CONTINUED: follows. An expanded discussion of tax consequences is available in the prospectus dated June 26, 1988, as amended March 18, 1994 related to the Plan. In general, 401(k) Company and Salary Reduction Contributions are not subject to tax when made. In addition, earnings and gains on a participant's account are not subject to tax when credited. Generally, distributions from the Plan are subject to tax in the year received from the Plan. However, under certain circumstances, a distribution, or part thereof, may not be taxed if rolled over to an Individual Retirement Account or other qualified plan. If taxable, a distribution may be eligible for special tax treatment under the IRC. In addition to regular taxes, most distributions received before a participant is age 59-1/2 will be subject to a 10% additional tax. Under limited circumstances, distributions in excess of IRC determined limits will be subject to a 15% excise tax. 11 THE ZENITH INVESTMENT PARTNERSHIP 401(k) PLAN ITEM 27A SCHEDULE OF ASSETS HELD FOR INVESTMENT PURPOSES AS OF DECEMBER 31, 1993 ___________ Current Description Cost Value - - ----------- ---- ------- Zenith National Insurance Corp.
