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 auditing standards generally accepted in the United States. 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 Plan at December 31, 2002 and 2001, and the changes in its net assets available for benefits for the year then ended, in conformity with accounting principles generally accepted in the United States. Our audits were performed for the purpose of forming an opinion on the financial statements taken as a whole. The accompanying supplemental schedule of assets (held at end of year) as of December 31, 2002, is presented for purposes of additional analysis and is not a required part of the financial statements but is 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 schedule is the responsibility of the Plan's management. The supplemental schedule has been subjected to the auditing procedures applied in our audit of the financial statements and, in our opinion, is fairly stated in all material respects in relation to the financial statements taken as a whole. /s/Ernst & Yount LLP Ernst & Young LLP Cincinnati, Ohio June 13, 2003 				 6 	 The Ohio Casualty Insurance Company Employee Savings Plan 	 Statements of Net Assets Available For Benefits 						 December 31, 					 2002 2001 					-------------- -------------- Assets Cash $ 1,460,516 $ 1,930,469 Investments, at fair value 106,359,413 128,352,033 Accrued interest 1,681 3,408 Contribution receivables: Employer 96,303 - Participants 256,666 - 					-------------- -------------- Total receivables 352,969 ------------- -------------- Net assets available for benefits $108,174,579 $130,285,910 					============= ============== 			 See accompanying notes 				 7 	 The Ohio Casualty Insurance Company Employee Savings Plan 	 Statement of Changes in Net Assets Available for Benefits 			Year Ended December 31, 2002 Additions Investment income: Net depreciation in fair value of investment $ (16,111,986) Interest and dividends 2,062,919 						 --------------- 							 (14,049,067) Contributions: Participants 9,075,438 Employer 2,965,134 						 --------------- 							 12,040,572 						 --------------- Total additions (2,008,495) Deductions Benefits paid directly to participants 20,085,866 Administrative expenses 16,970 						 --------------- 							 20,102,836 						 --------------- Net decrease (22,111,331) Net assets available for benefits: Beginning of year 130,285,910 -------------- End of year $ 108,174,579 						 =============== 				 See accompanying notes 					 8 	 The Ohio Casualty Insurance Company Employee Savings Plan 			 Notes To Financial Statements 				December 31, 2002 1. Accounting Policies: ------------------- The accompanying financial statements have been prepared on the accrual basis of accounting. A. Investment securities are stated at fair value. Shares of mutual 	funds are valued at quoted market prices, which represent the net 	asset values of shares held by the Ohio Casualty Insurance Company 	Employee Savings Plan (the Plan) at year-end. 	Securities traded on a national securities exchange, including Ohio 	Casualty Corporation common stock, are valued at the last recorded 	sales price of the last business day of the plan year. 	The fair value of the participation units owned by the Plan in common 	trust funds, are valued by the Trustees best efforts to maintain a 	stable net asset value of $1.00. Investments in the Managed Income 	Portfolio II Fund are valued at their estimated fair values, as 	determined in good faith by the Trustee. B. Interest income is recorded as earned. Dividend income is recorded 	on the ex-dividend date. C. Purchases and sales of securities are recorded on a trade-date basis. D. The Plan presents in the statement of changes in net assets available 	for benefits the net appreciation (depreciation) in the fair value of 	its investments which consists of the realized gains or losses and 	the unrealized appreciation (depreciation) on those investments. E. Contributions from participants and the Company are recorded in the 	month the Company makes payroll deductions from Plan participants. 	Participant contributions are accrued, if applicable, for the last 	pay period of the Plan year. F. Benefits are recorded by the Trustee when paid. G. The preparation of financial statements in conformity with accounting 	principles generally accepted in the United States requires 	management to make significant estimates and assumptions that affect 	the amounts reported in the financial statements and accompanying 	notes. Actual results could differ from those estimates. 				 9 	 The Ohio Casualty Insurance Company Employee Savings Plan 		 Notes To Financial Statements, Continued 				 December 31, 2002 2. Description of Plan: ------------------- The following brief description of the Plan is provided for general information purposes only. Reference should be made to the Plan Document and The Ohio Casualty Insurance Company Benefits Manual for a complete description of the Plan. A. General: 	The Plan, which is subject to provisions of the Employee Retirement 	Income Security Act of 1974 (ERISA), is a defined contribution plan 	covering all employees of the Company who have elected to participate. B. Participants of the Plan must be at least 18 years of age and be a 	full-time or part-time employee working 20 hours or more per week to 	be eligible. C. Participants direct the investment of their contributions into the 	fund options available. Participants may contribute between 1-32% of 	eligible compensation to the Plan on a before and/or after-tax basis. 	From January 1 through June 30, 2002, the Company matched 50% of the 	first 6% of eligible compensation contributed to the Plan and all of 	the employer contributions were directed to the Ohio Casualty Stock 	Fund. Effective July 1, 2002, employer contributions are invested 	according to the participant's investment direction. The Ohio 	Casualty Stock Fund is an Employee Stock Ownership Plan (ESOP). 	Eligible Plan participants can diversify a portion of these 	contributions after meeting the Plan's eligibility requirements (age 	55 and 10 years of Plan participation). Effective July 1, 2002, 	participants can diversify up to 25% of the employer contributions 	and investment earnings in the Ohio Casualty Stock Fund once per 	calendar quarter. In addition, participants are 100% vested in the 	value of their contributions and their investment earnings, as well 	as 100% vested in the value of the Company contributions and their 	investment earnings. D. Each participant's account is credited with his/her contributions, 	his/her share of the Company's contributions and an allocation of 	fund earnings. Allocations of fund earnings are based on 	participant's account balances, as defined by the Plan. The 	participant is entitled to his/her fully vested account balance. E. Certain costs of administering the Plan are paid by the Company. 	These costs totaled $74,158 and $70,464 for the years ended December 	31, 2002 and 2001. F. Benefits are payable to participants upon termination of employment, 	retirement, disability retirement, and/or death. In-service 	withdrawals, including withdrawals due to financial hardship as 	defined by the Internal Revenue Service, are also available. G. Effective January 1, 2001, Fidelity Investments became the 	recordkeeper and trustee for the Employee Savings Plan. All of the 	investment options, with the exception of the Interest Income Fund and 	the Ohio Casualty Stock Fund, were sold and reinvested on January 2, 	2001 in comparable funds offered by Fidelity Investments. The T. Rowe 	Price Small Cap Core Equity Fund Plan assets were transferred to 	the T. Rowe Price Small Cap Value Fund; the Vanguard Institutional 	Index Fund Plan assets were transferred to the Fidelity US Equity 	Index Pool Fund; ICAP FDS Equity Fund Plan assets were transferred to 	the Fidelity Equity Income Fund; 				 10 	 The Ohio Casualty Insurance Company Employee Savings Plan 		 Notes To Financial Statements, Continued 			 December 31, 2002 2. Description of Plan, Continued: ------------------------------ Vanguard Balanced Index Fund Plan assets were transferred to the Fidelity Balanced Fund; and CT&T FDS Montag & Caldwell Growth Fund Plan assets were transferred to the Fidelity Blue Chip Fund. 3. Plan Termination: ---------------- Although it has not expressed any intention to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions set forth in ERISA. In the event of Plan termination, the Plan's assets will be used to provide benefits for participants and beneficiaries in accordance with federal law. 4. Tax Status: ---------- The Plan has received a determination letter from the Internal Revenue Service dated February 4, 2003, stating that the Plan is qualified under Section 401(a) of the Internal Revenue Code (the Code) and, therefore, the related trust is exempt from taxation. However, subsequent to the issuance of the favorable determination letter, the Plan was amended. Once qualified, the Plan, as amended, is required to operate in conformity with the Code to maintain its qualification. The Plan Administrator believes the Plan, as amended, is being operated in compliance with the applicable requirements of the Code and, therefore, believes that the Plan is qualified and the related trust is tax exempt. 5.
