See pages 15 - B thru 15 - C 15 - A ANNUAL REPORT OF AMEREN SERVICES COMPANY For Year Ended December 31, 2003 Schedule XIV - Notes to Financial Statements NOTE 1 - Summary of Significant Accounting Policies Organization and Nature of Operations Ameren Services Company (the Company) is a wholly-owned subsidiary of Ameren Corporation (Ameren), registered under the Public Utility Holding Company Act of 1935 (PUHCA). The Company was authorized to conduct business as a service company for Ameren and its various subsidiaries by order of the Securities and Exchange Commission (SEC) dated December 30, 1997. The Company is organized along functional lines to accomplish its purpose of providing management, administrative, and technical services. These services are priced so that the Company operates on a break-even basis. The Company maintains its accounts in accordance with PUHCA, as administered by the SEC, and has adopted a system of accounts consistent with that prescribed by the Federal Energy Regulatory Commission. The accounting policies of the Company conform to U.S. generally accepted accounting principles (GAAP). Property and Plant The cost of additions to, and betterments of, units of property and plant is capitalized. Cost includes labor, material, applicable taxes and overheads. Maintenance expenditures and the renewal of items not considered units of property are charged to income as incurred. When units of depreciable property are retired, the original cost, less salvage value, are charged to accumulated depreciation. Asset removal costs incurred by our non rate-regulated operations, which do not constitute legal obligations, were expensed as incurred beginning in 2003. Asset removal costs accrued by our rate-regulated operations, which do not constitute legal obligations, are classified as a regulatory liability. Depreciation Depreciation is provided over the estimated lives of the various classes of depreciable property by applying composite rates on a straight-line basis. Cash and Cash Equivalents Cash and cash equivalents include cash on hand and temporary investments purchased with an original maturity of three months or less. Income Taxes Ameren and its subsidiaries file a consolidated federal tax return. Deferred tax assets and liabilities are recognized for the tax consequences of transactions that have been treated differently for financial reporting and tax return purposes, measured using statutory tax rates. The Company's expenses are billed to the other subsidiaries of Ameren and taxes are computed on those entities. The Company had no deferred tax assets or liabilities at December 31, 2003 and 2002. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions. Such estimates and assumptions affect reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reported periods. Actual results could differ from those estimates. Fair Value of Financial Instruments The carrying amounts of financial instruments on the Company's books are a reasonable estimate of their fair value. Pg 15 - B ANNUAL REPORT OF AMEREN SERVICES COMPANY For Year Ended December 31, 2003 Schedule XIV - Notes to Financial Statements NOTE 2 - Common Stock The Company is authorized to issue 30,000 shares of common stock at a par value of one cent ($.01) per share.

NOTE 3 - Financing Arrangements Ameren has money pool agreements among its subsidiaries to coordinate and provide for certain short-term cash and working capital requirements. The money pools are administered by the Company (see Note 4). Ameren also has bank credit agreements totaling $829 million , excluding the EEI facilities and the nuclear fuel lease facility, expiring at various dates between 2004 and 2005 that support a portion of Ameren's commercial paper programs. At December 31, 2003, $679 million of the bank credit agreements were unused and available. NOTE 4 - Related Party Transactions The Company has transactions in the normal course of business with other Ameren subsidiaries. These transactions are primarily comprised of services received or rendered. Intercompany receivables were approximately $52 million and $100 million, respectively, as of December 31, 2003 and 2002. Intercompany payables totaled approximately $24 million and $14 million, respectively, as of December 31, 2003 and 2002. Ameren's subsidiaries have the ability to invest excess funds or borrow funds as needed from Ameren's money pools. Interest is calculated at varying rates of interest depending on the composition of internal and external funds in the money pools. Excess funds that are not borrowed by other subsidiaries are invested externally by the Company and recorded as an intercompany note payable on the Company's balance sheet. Intercompany notes payable were approximately $603 million and $452 million, respectively, as of December 31, 2003 and 2002. NOTE 5 - Retirement Benefits The Ameren retirement plans cover substantially all employees of the Company. Benefits are based on the employees' years of service and compensation. The Ameren plans are funded in compliance with income tax regulations and federal funding requirements. The Company, along with the other subsidiaries of Ameren, is a participant in the Ameren plans and is responsible for its proportional share of the costs. The Company's share of the pension costs for 2003 and 2002 was approximately $11 million and $4 million, respectively. In addition to providing pension benefits, the Company provides certain health care and life insurance benefits for retired employees. The Ameren Postretirement Plans cover substantially all employees of the Company.
