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 the standards of the Public Company Accounting Oversight Board (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, 2003 and 2002, and the changes in its net assets available for benefits for the year ended December 31, 2003, in conformity with U.S. generally accepted accounting principles. 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, 2003, 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 & Young LLP Ernst & Young LLP Cincinnati, Ohio June 18, 2004 				 6 	 The Ohio Casualty Insurance Company Employee Savings Plan 		Statements of Net Assets Available For Benefits 						December 31, 					 2003 2002 				 -------------- -------------- Assets Cash: Noninterest-bearing cash $ 34,765 $ - Investments, at fair value 135,092,955 107,819,929 Receivables: Employer contributions - 96,303 Participants contributions - 256,666 Due from broker for securities sold 197,340 - Accrued interest 1,380 1,681 					------------- ------------- Total receivables 198,720 354,650 					------------- ------------- Net assets available for benefits $135,326,440 $108,174,579 					============= ============= 			 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, 2003 Additions Investment income: Net appreciation in fair value of investments $ 23,459,431 Interest and dividends 2,194,039 						 ------------- 							25,653,470 Contributions: Participants 8,090,849 Employer 2,859,518 						 ------------- 							10,950,367 						 ------------- Total additions 36,603,837 Deductions Benefits paid directly to participants 9,430,166 Administrative expenses 21,810 						 ------------- Total deductions 9,451,976 						 ------------- Net increase in net assets available for benefits 27,151,861 Net assets available for benefits: Beginning of year 108,174,579 						 -------------- End of year $135,326,440 						 ============== 			 See accompanying notes 				 8 	 The Ohio Casualty Insurance Company Employee Savings Plan 			Notes To Financial Statements 			 December 31, 2003 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 market 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 at quoted redemption value as of the last 	business day of the plan year. 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 Ohio Casualty Insurance 	Company (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 when paid. G. The preparation of financial statements in conformity with U.S. 	generally accepted accounting principles 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. 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 eligible employees of the Company who have elected to 	participate. 				 9 	 The Ohio Casualty Insurance Company Employee Savings Plan 		 Notes To Financial Statements, Continued 				December 31, 2003 2. Description of Plan, continued: ------------------------------ B. Participants of the Plan must be at least 18 years of age and be a 	Full-time or Part-time employee of the Company working 20 or more 	hours per week, or work 1,000 or more hours in a calendar year, to be 	eligible. C. Participants direct the investment of their contributions into 	various fund options available. Participants may contribute between 	1-32% of eligible compensation to the Plan on a before-tax and/or 	after-tax basis. The Company matches 50% of the first 6% of the 	participant's semi-monthly contribution. Effective since July 1, 	2002, the Company match is invested according to the participants' 	investment direction. Prior to this date all Company match was 	invested as directed by the Company into the Ohio Casualty Stock 	Fund. Also effective after July 1, 2002, participants can diversify 	up to 25% of their employer contributions and investment earnings in 	the Ohio Casualty Stock Fund once per calendar quarter. The Ohio 	Casualty Stock Fund is an Employee Stock Ownership Plan (ESOP). 	Participants are 100% vested in the value of their own contributions 	and related investment earnings, as well as 100% vested in the value 	of the Company match contributions and related 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 	participants' account balances, as defined by the Plan. The benefit 	to which a participant is entitled is the benefit that can be 	provided from his/her fully vested account balance. E. Certain costs of administering the Plan are paid by the Company. 	These costs totaled $55,363 for the year ended December 31, 2003. 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. 3. Plan Termination: ---------------- Although it has not expressed any intent 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. 				 10 	 The Ohio Casualty Insurance Company Employee Savings Plan 		 Notes To Financial Statements, Continued 				December 31, 2003 4. Income 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. Subsequent to this determination by the Internal Revenue Service, the Plan was amended. Once qualified, the Plan is required to operate in conformity with the Code to maintain its qualification. The Plan Administrator believes that 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. Investments: ----------- The following investments represent 5% or more of the Plan's net assets: 								 Fair Value 						 ------------------------------- 							December 31, December 31, 							 2003 2002 						 ------------------------------- Common Stock - ------------ Ohio Casualty Stock Fund $33,005,492 $27,627,296 Mutual Funds - ------------ T.

Nonparticipant-Directed Investments: ----------------------------------- Effective July 1, 2002, the Company amended the Plan to allow participants the opportunity to direct the investments of all Company match contributions. The amendment also granted all participants the opportunity to diversify (up to 25% once per calendar quarter) their Company match account balances that, prior to the amendment, were initially invested entirely in the Ohio Casualty Stock Fund by the Company under nonparticipant-direction. In all plan years subsequent to the current plan year ended December 31, 2003, investments in the Ohio Casualty Stock Fund can be considered participant-directed. In the current plan year, however, the participant-directed and nonparticipant- directed components of the Ohio Casualty Stock Fund cannot be separately determined; therefore, the fund activity is deemed to be nonparticipant- directed for purposes of this disclosure as defined in Statement of Position 99-3, "Accounting for and Reporting of Certain Defined Contribution Benefit Plan Investments and Other Disclosure Matters." Accordingly, the information about the net assets and the significant components of changes in net assets as is required for disclosure for nonparticipant-directed investments is as follows: 						 December 31, 						 2003 2002 						 ---- ---- Investments, at fair value; Nonparticipant-Directed: Ohio Casualty Stock Fund $ 0 $27,531,834 					 =========== =========== Investments, at fair value; Participant-Directed: Ohio Casualty Stock Fund $33,005,492 $ 0 					 =========== =========== 								 Year ended 								 December 31, 2003 								 ----------------- Change in nonparticipant-directed net assets: 	Interest income $ 15,473 	Contributions 520,297 	Interfund transfers (1,379,246) 	Net loan activity 11,068 	Net appreciation in fair value of investments 8,548,316 	Benefits paid directly to participants (2,242,250) 	Transfers to participant-directed investments (33,005,492) 								 ------------- Net decrease in nonparticipant-directed investments $(27,531,834) 								 ============= 7. Loans Receivable - Participants: ------------------------------- Participants are permitted to borrow from the trust using their vested account balance as collateral. The minimum loan amount is $1,000 and the maximum loan amount is the lesser of $50,000 reduced by the participant's highest outstanding aggregate balance of loans from the Plan during the previous twelve months, the total value of the participant's before-tax, after-tax, and rollover accounts, or 50% of the vested value of the participant's accounts. Interest is charged at Chase Manhattan Bank's commercial rate plus 1%. Repayment of loans are arranged through payroll deductions with a maximum repayment term of 5 years, or 15 years for a home loan. Terminated employees can continue loan repayments following termination of employment. 				 12 	 The Ohio Casualty Insurance Company Employee Savings Plan 		 Notes To Financial Statements, Continued 				December 31, 2003 8.

Subsequent Events: ----------------- Effective January 1, 2005, the Company will match 100% of the participant's contribution for the first 3% of eligible pay and 50% of the participant's contribution for the next 2% of eligible pay. Employees with 10 or more years of service as of July 1, 2004 will be eligible for a temporary, discretionary, additional Company contribution of 2.5% percent of eligible compensation. Additionally, a discretionary profit sharing contribution may be made by the Company each year beginning in 2005 if certain profitability levels are achieved. Employees will not have to contribute to the Plan to be eligible for the profit sharing contribution but must be employed by the Company on December 31st of the applicable Plan year. 				 13 			 Supplemental Schedule 	 Schedule H, Line 4i - Schedule of Assets (Held at End of Year) The Ohio Casualty Insurance Company Employee Savings Plan Schedule H, Line 4i - Schedule of Assets (Held At End of Year) EIN 31-0396250 Plan Number 002 INVESTMENTS UNITS/SHARE FAIR VALUE - ---------------------------- ------------ ------------ Cash: Interest-bearing cash 15,814 $ 1,471,079 Common Stock: Ohio Casualty Corporation* 354,803 33,005,492 Mutual Funds: PIMCO Tot Return Adm 74,308 795,834 Franklin Small Cap Growth 61,189 1,849,132 T.
