UNITED STATES SECURITIES AND EXCHANGE COMMISSION Washington, D.C. 20549 ----------------------- FORM 8-K/A CURRENT REPORT Pursuant to Section 13 or 15(d) of The Securities Exchange Act of 1934 ----------------------- January 3, 2002 Date of Report MARATHON OIL CORPORATION ------------------------------------------------------------------------------- (Exact Name of Registrant as Specified in Charter) Delaware 1-5153 25-0996816 -------------------- ------------------------- --------------------- State or Other Jurisdiction of Commission File Number IRS Employer Incorporation Identification Number 5555 San Felipe Road, Houston, TX 77056-2723 ----------------------------------------------- (Address of Principal Executive Offices) (713) 629-6600 ------------------------------ (Registrant's telephone number, including area code) USX CORPORATION -------------------------------------------------------- (Former Name or Former Address, if Changed Since Last Report) ITEM 7. Financial Statements, Pro Forma Financial Information and Exhibits. (a) Not applicable. (b) On January 3, 2002, Marathon Oil Corporation, formerly known as USX Corporation (the "Company"), filed a current report on Form 8-K to report the completion of the separation of its steel and energy businesses pursuant to the Agreement and Plan of Reorganization, dated as of July 31, 2001, by and between the Company and United States Steel LLC (the "Plan of Reorganization"). Pursuant to Item 7 of Form 8-K, the Company indicated that it would file the unaudited pro forma financial information required to be filed under Item 7 of Form 8-K by amendment. This amendment is being filed to provide the required financial information. (c) Not applicable. UNAUDITED PRO FORMA CONDENSED FINANCIAL STATEMENTS FOR MARATHON OIL CORPORATION The following unaudited pro forma condensed financial statements give effect to the separation and significant transactions related to the separation of USX Corporation (renamed Marathon Oil Corporation) into two separate companies, Marathon Oil Corporation and United States Steel Corporation (the "Separation"). Pro forma adjustments have been made to reflect the presentation of the businesses of United States Steel Corporation as discontinued operations, the effects of the redemptions/conversion of preferred securities, costs directly attributable to the Separation, and the separation of the businesses of United States Steel Corporation through a tax-free distribution of United States Steel Corporation shares to the holders of USX--U. S. Steel Group shares. The following unaudited pro forma condensed balance sheet as of September 30, 2001 gives effect to the Separation and significant transactions related to the Separation, as if such transactions had been consummated as of September 30, 2001. The following unaudited pro forma condensed statements of operations for the nine months ended September 30, 2001 and the year ended December 31, 2000 give effect to the Separation and significant transactions related to the Separation as if such transactions were consummated at the beginning of the periods presented. The unaudited pro forma condensed statements of operations of Marathon Oil Corporation for the years ended December 31, 1999 and 1998 reflect the businesses of United States Steel Corporation as discontinued operations but do not give effect to any adjustments associated with the Separation. No pro forma adjustments were made for changes in the future level of corporate administrative costs to be incurred by Marathon Oil Corporation as compared with the historical level of such costs allocated to the Marathon Group. These costs are expected to continue at approximately the same level as previously allocated, except for insurance costs, which are estimated to increase by $5 million annually. Nonrecurring costs directly attributable to the Separation, including the costs to complete the Separation and the loss on Separation, have not been reflected in the unaudited pro forma condensed statements of operations. Pro forma adjustments have been made to remove the effects of the nonrecurring costs directly attributable to the Separation that were incurred and recorded in the historical accounts of Marathon Oil Corporation during the nine months ended September 30, 2001. However, pro forma adjustments have been made to reflect all nonrecurring costs directly attributable to the Separation in the unaudited pro forma condensed balance sheet. The pro forma adjustments included herein are based on available information and certain assumptions that management believes are reasonable and are described in the accompanying notes. The unaudited pro forma condensed financial statements do not necessarily represent Marathon Oil Corporation's financial position or results of operations had the Separation and significant transactions related to the Separation occurred at such dates or project Marathon Oil Corporation's financial position or results of operations for any future date or period. In the opinion of management, all adjustments necessary to present fairly the unaudited pro forma condensed financial statements have been made. The unaudited pro forma condensed financial statements should be read in conjunction with the historical financial statements of USX, including the notes thereto, included in USX's Form 10-K, as amended, for the year ended Decmber 31, 2000 and the Form 10-Q for the quarterly period ended September 30, 2001, which were filed with the SEC, and which are hereby incorporated in this document by reference.

(B) Reflects the establishment of revenues and the related cost of revenues for intercompany sales previously eliminated in consolidation. (C) Reflects the reversal of general corporate overhead expenses allocated to United States Steel Corporation that are not permitted to be reflected in discontinued operations. (D) Reflects the reversal of a portion of the interest expense allocated to United States Steel Corporation that is not permitted to be reflected in discontinued operations. The only period in which allocated interest exceeded the permitted amount was the nine months ended September 30, 2001. (E) Reflects the income tax effects of adjustments (C) and (D). (F) Reflects the removal of nonrecurring costs directly attributable to the Separation that were incurred during the nine months ended September 30, 2001, that were included in the historical accounts of Marathon Oil Corporation. There were no costs related to the Separation incurred prior to the nine months ended September 30, 2001. (G) Reflects an increase in net interest and other financial costs, primarily due to the increase in the amount of indebtedness of Marathon Oil Corporation following the Separation. The increase primarily reflects the $900 million value transfer with United States Steel Corporation and incremental interest effects associated with the redemptions/conversion of the preferred securities. Pro forma interest costs have been calculated based on average levels of pro forma debt for the nine months ended September 30, 2001, and the year ended December 31, 2000. Pro forma debt reflects the redemptions/conversion of the preferred securities and repayment of the Marathon Oil Corporation receivables facility with proceeds from new financings obtained by United States Steel Corporation and drawings on the Marathon Oil Corporation revolving credit facility. For the majority of the year 2000, the amount of debt that would have remained with Marathon Oil Corporation was less than the net debt levels attributed to the Marathon Group, after adjusting for the $900 million value transfer. As a result, average pro forma debt for 2000 reflects drawings on the Marathon Oil Corporation revolving credit facility to fund the redemptions/conversion of the preferred securities and to repay the receivables facility. The assumed interest rate for new financings was 5% in 2001 and 7% in 2000, which was based on the average borrowing rates on the revolving credit facility. A 1/8 percentage point change in the assumed financing rate would have changed annualized interest expense by less than $1 million. (H) Reflects the income tax effects of adjustment (F) and (G). (I) Reflects the elimination of discontinued operations as a result of the Separation. Also includes amounts related to general corporate overhead expenses and interest expense allocated to United States Steel Corporation but were not classified as discontinued operations. (J) Weighted average shares of common stock outstanding were 309,056,000 (basic) and 309,452,000 (diluted) for USX--Marathon Group and, on a pro forma basis, Marathon Oil Corporation for the nine months ended September 30, 2001. Weighted average shares of common stock outstanding were 311,531,000 (basic) and 311,761,000 (diluted) for USX--Marathon Group, and on a pro forma basis, Marathon Oil Corporation for the year ended December 31, 2000. Weighted average shares of common stock outstanding (basic and diluted) for the USX--U. S. Steel Group were 89,003,000 for the nine months ended September 30, 2001, and 88,613,000 for the year ended December 31, 2000. Preferred stock dividends of $6 million and $8 million reduced net income applicable to USX--U. S. Steel Group shares for the nine months ended September 30, 2001, and for the year ended December 31, 2000, respectively.
