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 year ended December 31, 2004, 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 1 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 June 20, 2005 2 Apache Corporation 401(k) Savings Plan Statements of Net Assets Available for Benefits DECEMBER 31 2004 2003 --------------- --------------- ASSETS Receivables: Securities sold $ 36,588 $ 75,546 Investments 206,392,999 168,781,076 --------------- --------------- Net assets available for benefits $ 206,429,587 $ 168,856,622 =============== =============== See accompanying notes. 3 Apache Corporation 401(k) Savings Plan Statement of Changes in Net Assets Available for Benefits Year ended December 31, 2004 Additions: Participant contributions $ 8,578,504 Employer contributions 6,075,750 Rollover contributions 2,378,298 Investment income 3,941,584 Net appreciation in fair value of investments 24,138,542 ---------------- Total additions 45,112,678 Deductions: Administrative fees 51,383 Benefits paid to participants 7,488,330 ---------------- Total deductions 7,539,713 ---------------- Net increase 37,572,965 Net assets available for benefits at: Beginning of year 168,856,622 ---------------- End of year $ 206,429,587 ================ See accompanying notes. 4 Apache Corporation 401(k) Savings Plan Notes to Financial Statements December 31, 2004 1. DESCRIPTION OF PLAN The following brief description of the Apache Corporation 401(k) Savings Plan (the "Plan") is provided only for general information purposes. Participants should refer to the Summary Plan Description for more complete information, a copy of which is available from Apache Corporation (the "Company") or is accessible through the Company's internet site. The Plan is a defined contribution plan established on January 1, 1989, open to all eligible employees and is subject to the provisions of the Employee Retirement Income Security Act of 1974 ("ERISA"). CONTRIBUTIONS Participants may contribute up to 25% of their eligible compensation. The Company makes a basic contribution equal to 100% of the first 6% of each participant's contributions. Participants direct the investment of all contributions to their accounts into various fund options offered by the Plan. Only participant contributions are eligible to be invested in the self directed brokerage account. VESTING Participants are fully vested in their contributions and all related earnings. Vesting in the employer contribution portion of their accounts and related earnings is based on years of credited service. A participant becomes 20% vested after completion of one year of service and continues to vest 20% per year, becoming fully vested after completion of five years of credited service. Forfeitures of unvested accounts may be used by the Company to reduce future employer contributions to the Plan or pay administrative expenses of the Plan. PARTICIPANT LOANS Participants may borrow from their own contributions a minimum of $500, up to the lesser of $50,000 less the participant's highest outstanding loan balance during the preceding 12 months or 50% of their vested account balance. Loans are charged at a rate of interest equal to the current prime lending rate plus 1%. Loans must generally be repaid through payroll deductions within four years. 5 Apache Corporation 401(k) Savings Plan Notes to Financial Statements (continued) 1. DESCRIPTION OF PLAN (CONTINUED) BENEFIT PAYMENTS Participants are eligible to receive lump-sum benefits equal to the vested value of their account in the event of retirement, disability, death, or termination of employment. 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 of ERISA. In the event of Plan termination, participants become fully vested. ADMINISTRATIVE EXPENSES Certain administrative expenses of the Plan are paid by the Company. 2. SUMMARY OF ACCOUNTING POLICIES BASIS OF ACCOUNTING The accompanying financial statements of the Plan have been prepared on the accrual basis of accounting in accordance with U.S. generally accepted accounting principles. Benefit payments are recorded when paid. 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 reported amounts in the financial statements, accompanying notes and supplemental schedule. Actual results could differ from those estimates. INVESTMENT VALUATION AND INCOME RECOGNITION Fidelity Management Trust Company serves as the Plan's trustee and holds all investments of the Plan, except for the self-directed brokerage account which is held by Fidelity Brokerage Services. Investments in mutual funds and common stock are stated at fair value based on quotations obtained from national securities exchanges. The 6 Apache Corporation 401(k) Savings Plan Notes to Financial Statements (continued) 2. SUMMARY OF ACCOUNTING POLICIES (CONTINUED) INVESTMENT VALUATION AND INCOME RECOGNITION (CONTINUED) investment in the common collective trust fund is stated at fair value as determined by the issuer, based on quoted market values of the underlying investments. The money market fund and participant loans are stated at cost, which approximates fair value. Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date. RISKS AND UNCERTAINTIES The Plan provides for investments in various investment securities which, in general, are exposed to various risks, such as interest rate, credit, and overall market volatility. Due to the level of risk associated with certain investments securities, it is reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect the amounts reported in the statements of net assets available for benefits and participant account balances. 3. INVESTMENTS Individual investments that represent 5% or more of the Plan's net assets are as follows: DECEMBER 31 2004 2003 ---------------- ---------------- Apache Corporation common stock $ 89,509,075 $ 71,092,288 Fidelity Blue Chip Growth Fund 9,795,186 9,609,072 Fidelity Magellan Fund 20,794,027 20,214,961 Fidelity Managed Income Portfolio 16,426,244 14,072,304 Fidelity Retirement Money Market Portfolio 8,822,802 8,591,870 Fidelity Equity-Income Fund 11,979,213 9,547,067 Fidelity Low-Priced Stock Fund 13,327,374 8,989,694 7 Apache Corporation 401(k) Savings Plan Notes to Financial Statements (continued) 3. INVESTMENTS (CONTINUED) During 2004, the Plan's investments (including investments bought, sold, and held during the year) appreciated in value as follows: YEAR ENDED DECEMBER 31 2004 ------------- Mutual funds $ 5,445,596 Common stocks 18,692,946 ------------- $ 24,138,542 ============= 4. INCOME TAX STATUS The Plan received a determination letter from the Internal Revenue Service ("IRS") dated July 22, 2002, stating that the Plan is qualified under Section 401(a) of the Internal Revenue Code (the "IRC") and, therefore, the related trust is exempt from taxation. Subsequent to this determination by the IRS, the Plan was amended and restated. Once qualified, the Plan is required to operate in conformity with the IRC to maintain its Section 401(a) qualification. The plan administrator believes the Plan is being operated in compliance with the applicable requirements of the IRC and, therefore, believes that the Plan, as amended and restated, is qualified and the related trust is tax exempt. 8 Supplemental Schedule Apache Corporation 401(k) Savings Plan Schedule H, Line 4(i) - Schedule of Assets (Held At End of Year) EIN: 41-0747868 PN: 002 December 31, 2004 IDENTITY OF ISSUE, BORROWER, LESSOR, OR SIMILAR PARTY DESCRIPTION OF INVESTMENT CURRENT VALUE -------------------------------------------------------------------------------------------------------- * Apache Corporation 1,770,003 shares of common stock $ 89,509,075 * Fidelity Investments Fidelity Puritan Fund 4,620,310 * Fidelity Investments Fidelity Equity-Income Fund 11,979,213 * Fidelity Investments Fidelity Intermediate Bond Fund 7,369,927 * Fidelity Investments Fidelity Blue Chip Growth Fund 9,795,186 * Fidelity Investments Fidelity Magellan Fund 20,794,027 * Fidelity Investments Fidelity Growth Company Fund 4,622,419 * Fidelity Investments Fidelity Retirement Money Market Portfolio 8,822,802 Morgan Stanley Morgan Stanley Institutional Fund, Inc. - Intermediate Equity Portfolio 4,532,382 * Fidelity Investments Fidelity Managed Income Portfolio 16,426,244 * Fidelity Investments Spartan U.
