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. We were not engaged to perform an audit of the Plan's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Plan's internal control over financial reporting. Accordingly, we express no such opinion. An audit also 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. 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, 2004 and 2003, and the changes in its net assets available for benefits for the years then ended, 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, 2004, 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. This supplemental schedule is the responsibility of the Plan's management. The supplemental schedule has been subjected to the auditing procedures applied in our audits 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 St. Louis, Missouri June 2, 2005 1 Lee Ranch Coal Company Retirement and Savings Plan Statements of Net Assets Available for Benefits DECEMBER 31 2004 2003 ----------- ----------- ASSETS Investments, at fair value: Investments in mutual funds $ 9,921,462 $ 8,732,976 Investment in common/collective trust 6,605,823 6,211,073 Investment in Peabody Energy Stock Fund 100,203 13,907 Participant notes receivable 1,383,011 1,321,047 ----------- ----------- Net assets available for benefits $18,010,499 $16,279,003 =========== =========== See accompanying notes. 2 Lee Ranch Coal Company Retirement and Savings Plan Statements of Changes in Net Assets Available for Benefits YEAR ENDED DECEMBER 31 2004 2003 ------------ ------------ ADDITIONS Interest and dividends $ 540,701 $ 460,869 Net realized and unrealized appreciation of investments 785,158 1,435,460 ------------ ------------ Net investment income 1,325,859 1,896,329 ------------ ------------ Contributions: Employee 1,026,216 1,113,086 Employer 425,173 462,342 Rollovers 9,302 87,959 ------------ ------------ Total contributions 1,460,691 1,663,387 ------------ ------------ Total additions 2,786,550 3,559,716 ------------ ------------ DEDUCTIONS Withdrawals by participants (1,051,540) (654,354) Administrative expenses (3,514) (3,270) ------------ ------------ Total deductions (1,055,054) (657,624) ------------ ------------ Net increase in net assets available for benefits 1,731,496 2,902,092 Net assets available for benefits at beginning of year 16,279,003 13,376,911 ------------ ------------ Net assets available for benefits at end of year $ 18,010,499 $ 16,279,003 ============ ============ See accompanying notes. 3 Lee Ranch Coal Company Retirement and Savings Plan Notes to Financial Statements Years Ended December 31, 2004 and 2003 1. DESCRIPTION OF THE PLAN The following description of the Lee Ranch Coal Company (the "Company") Retirement and Savings Plan (the "Plan") provides only general information. Participants should refer to the plan documents for a more complete description of the Plan's provisions. The Company is an indirect, wholly-owned subsidiary of Peabody Energy Corporation. GENERAL The Plan is a defined contribution plan covering all employees of the Company. Participation in the Plan is voluntary, and employees are eligible for participation on the date of their employment or at any time afterward. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 ("ERISA"). The Plan allows participants to invest in a selection of mutual funds, a common/collective trust, and the Peabody Energy Stock Fund. All investments in the Plan are participant-directed. CONTRIBUTIONS Each year, participants may contribute any whole percentage from 2% to 50% of pre-tax base compensation, as defined in the Plan. After-tax contributions are allowed only after a participant has exceeded the annual IRC 402(g) limits. Participants may also contribute distributions from other qualified defined benefit or defined contribution plans. In the calendar year that a participant is age 50 or older and each year thereafter, certain participants meeting additional specific criteria are permitted to make catch-up contributions to the Plan. These participants are able to contribute amounts in excess of the maximum otherwise permitted by the Plan, subject to certain limitations. The Company makes matching contributions equal to 100% of the first 4% of base compensation that a participant contributes to the Plan on a pretax basis. After a participant's pretax contributions reach the pretax limit established by the Internal Revenue Service ("IRS"), the Company matches 100% of the first 4% of base compensation that a participant contributes to the Plan on an after-tax basis. Participants direct the investment of employee and employer matching contributions into various investment options offered by the Plan. All contributions are subject to certain limitations as defined by the Plan and the IRS. 4 Lee Ranch Coal Company Retirement and Savings Plan Notes to Financial Statements (continued) 1. DESCRIPTION OF THE PLAN (CONTINUED) FORFEITED ACCOUNTS Employer contributions are reduced by forfeitures of non-vested amounts. The forfeiture credits, net of holding gains or losses, amounted to $12,114 and $43,966 for the years ended December 31, 2004 and 2003, respectively. As of December 31, 2004 and 2003, the forfeiture credits that were available for future use amounted to $20,667 and $8,369, respectively. PARTICIPANT LOANS Participants may borrow up to 50% of their vested account balance from their fund accounts, subject to a minimum of $1,000 and a maximum of $50,000. The loans are secured by the balance in the participant's account and bear interest at the prime interest rate as published in The Wall Street Journal on the first business day of the month in which the loan was made, plus 1%. Principal and interest are paid ratably through payroll deductions. A maximum of two loans may be outstanding at any time. PARTICIPANT ACCOUNTS Each participant's account is credited with the participant's contributions, the Company's contributions, and plan earnings. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested account. PAYMENT OF BENEFITS Participants are eligible for distributions of their vested account balance upon termination of employment. Participants are eligible for distribution of their entire account balance at death, disability or retirement after age 65. Generally, participants may elect to receive their distribution as a lump sum or annual installment. A beneficiary distribution is available as a lump sum only. Participants who have attained the age of 59 1/2 have the right to receive a partial or complete distribution of their vested account balance upon request, without penalty. Withdrawals in cases of hardship, as defined in the Plan, are also permitted. Other withdrawals of after-tax contributions are also available as defined in the Plan. 5 Lee Ranch Coal Company Retirement and Savings Plan Notes to Financial Statements (continued) 1. DESCRIPTION OF THE PLAN (CONTINUED) VESTING Participants are immediately vested in their contributions and actual earnings thereon. Vesting in Company matching contributions occurs ratably based on years of continuous service (20% for each year of service, as defined, with 100% vesting after five years of service), and automatically vests completely when the participant attains the age of 65. PLAN TERMINATION The Plan is voluntary on the part of the Company. The Company may terminate the Plan in whole or in part subject to the provisions of ERISA. Upon termination or complete discontinuance of all contributions to the Plan, participants' accounts become fully vested. Currently, the Company has no intention to terminate the Plan. ADMINISTRATIVE EXPENSES All significant administrative expenses of the Plan are paid by the Company. Participants are required to pay their own loan fees. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES BASIS OF PRESENTATION The financial statements of the Plan are prepared under the accrual method of accounting. USE OF ESTIMATES The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. VALUATION OF INVESTMENTS AND INCOME RECOGNITION The Plan's investments are stated at fair value. Shares of mutual funds are valued at quoted market prices which represent the net asset value of shares held by the Plan at year-end. Units in the common/collective trust are valued at net asset value at year-end. The stock fund is valued at year-end unit closing price (comprised of the year-end market price plus any uninvested cash position). Participant loans are valued at cost, which approximates market value. 6 Lee Ranch Coal Company Retirement and Savings Plan Notes to Financial Statements (continued) 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded when earned. Dividends are recorded on the ex-dividend date. Capital gain distributions are included in dividend income. PAYMENT OF BENEFITS Benefits are recorded when paid. 3. RELATED PARTY TRANSACTIONS The Plan invests in shares of mutual funds managed by an affiliate of its trustee, Vanguard Fiduciary Trust Company, a party-in-interest with respect to the Plan. These transactions are covered by an exemption from the "prohibited transaction" provisions of ERISA and the Internal Revenue Code of 1986 (the "Code"), as amended. The Plan also invests in Peabody Energy Corporation stock, through the Peabody Energy Stock Fund, which is a permitted party-in-interest transaction. 4. INVESTMENTS The Plan's investments, including those purchased, sold or held during the year, appreciated in fair value as determined by quoted market prices as follows: 2004 2003 ---------- ---------- Mutual funds $ 746,072 $1,431,603 Peabody Energy Stock Fund 39,086 3,857 ---------- ---------- $ 785,158 $1,435,460 ========== ========== 7 Lee Ranch Coal Company Retirement and Savings Plan Notes to Financial Statements (continued) 4. INVESTMENTS (CONTINUED) Investments representing 5% or more of the fair value of the Plan's net assets at December 31 were as follows: 2004 2003 ------------ ---------- Mutual funds: Vanguard 500 Index Fund $ 3,603,523 $3,314,204 Vanguard Prime Money Market LESS THAN 5% 977,803 Vanguard U.S. Growth Portfolio LESS THAN 5% 816,432 Vanguard Wellington Fund 1,115,443 931,446 Vanguard Windsor II Fund 1,354,069 1,071,250 Common/collective trust: Vanguard Retirement Savings Trust 6,605,823 6,211,073 5. INCOME TAX STATUS The Plan received a determination letter from the IRS dated May 2, 2003, stating that the Plan is qualified under Section 401(a) of the Code and, therefore, the related trust is exempt from taxation. Once qualified, the Plan is required to operate in conformity with the Code to maintain its qualification. The Plan was amended subsequent to the IRS determination letter. The Plan's administrator believes the Plan is being operated in compliance with the applicable requirements of the Code and, therefore, believes the Plan, as amended, is qualified and the related trust is tax-exempt. The Plan's sponsor has indicated that it will take the necessary steps, if any, to maintain the Plan's qualified status. 6. RISKS AND UNCERTAINTIES The Plan invests in various investment securities. Investment securities are exposed to various risks such as interest rate, market and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect participants' account balances and the amounts reported in the statements of net assets available for benefits. 8 Lee Ranch Coal Company Retirement and Savings Plan Notes to Financial Statements (continued) 7. SUBSEQUENT EVENT Effective January 1, 2005, Peabody Investments Corp. became the sponsor of the Lee Ranch Coal Company Retirement and Savings Plan.
