M-35 Management's Report The accompanying financial statements of the Marathon Group are the responsibility of and have been prepared by USX Corporation (USX) in conformity with generally accepted accounting principles. They necessarily include some amounts that are based on best judgments and estimates. The Marathon Group financial information displayed in other sections of this report is consistent with these financial statements. USX seeks to assure the objectivity and integrity of its financial records by careful selection of its managers, by organizational arrangements that provide an appropriate division of responsibility and by communications programs aimed at assuring that its policies and methods are understood throughout the organization. USX has a comprehensive formalized system of internal accounting controls designed to provide reasonable assurance that assets are safeguarded and that financial records are reliable. Appropriate management monitors the system for compliance, and the internal auditors independently measure its effectiveness and recommend possible improvements thereto. In addition, as part of their audit of the financial statements, USX's independent accountants, who are elected by the stockholders, review and test the internal accounting controls selectively to establish a basis of reliance thereon in determining the nature, extent and timing of audit tests to be applied. The Board of Directors pursues its oversight role in the area of financial reporting and internal accounting control through its Audit Committee. This Committee, composed solely of nonmanagement directors, regularly meets (jointly and separately) with the independent accountants, management and internal auditors to monitor the proper discharge by each of its responsibilities relative to internal accounting controls and the consolidated and group financial statements. Thomas J. Usher Robert M. Hernandez Kenneth L. Matheny Chairman, Board of Directors Vice Chairman Vice President & Chief Executive Officer & Chief Financial Officer & Comptroller Report of Independent Accountants To the Stockholders of USX Corporation: In our opinion, the accompanying financial statements appearing on pages M-2 through M-20 present fairly, in all material respects, the financial position of the Marathon Group at December 31, 1997 and 1996, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 1997, in conformity with generally accepted accounting principles. These financial statements are the responsibility of USX's management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements in accordance with generally accepted auditing standards which 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, 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 the opinion expressed above. As discussed in Note 7, page M-9, in 1995 USX adopted a new accounting standard for the impairment of long-lived assets. The Marathon Group is a business unit of USX Corporation (as described in Note 1, page M-5); accordingly, the financial statements of the Marathon Group should be read in connection with the consolidated financial statements of USX Corporation.

The accompanying notes are an integral part of these financial statements. M-4 Notes to Financial Statements 1. BASIS OF PRESENTATION After the redemption of the USX - Delhi Group stock on January 26, 1998, USX Corporation (USX) has two classes of common stock: USX - Marathon Group Common Stock (Marathon Stock) and USX - U. S. Steel Group Common Stock (Steel Stock), which are intended to reflect the performance of the Marathon Group and the U. S. Steel Group, respectively. The financial statements of the Marathon Group include the financial position, results of operations and cash flows for the businesses of Marathon Oil Company and certain other subsidiaries of USX, and a portion of the corporate assets and liabilities and related transactions which are not separately identified with ongoing operating units of USX. The Marathon Group is involved in worldwide exploration, production, transportation and marketing of crude oil and natural gas; domestic refining, marketing and transportation of petroleum products; and power generation. The Marathon Group financial statements are prepared using the amounts included in the USX consolidated financial statements. Although the financial statements of the Marathon Group and the U. S. Steel Group separately report the assets, liabilities (including contingent liabilities) and stockholders' equity of USX attributed to each such group, such attribution of assets, liabilities (including contingent liabilities) and stockholders' equity among the Marathon Group and the U. S. Steel Group for the purpose of preparing their respective financial statements does not affect legal title to such assets or responsibility for such liabilities. Holders of Marathon Stock and Steel Stock are holders of common stock of USX and continue to be subject to all the risks associated with an investment in USX and all of its businesses and liabilities. Financial impacts arising from one Group that affect the overall cost of USX's capital could affect the results of operations and financial condition of the other Group. In addition, net losses of either Group, as well as dividends and distributions on any class of USX Common Stock or series of preferred stock and repurchases of any class of USX Common Stock or series of preferred stock at prices in excess of par or stated value, will reduce the funds of USX legally available for payment of dividends on both classes of Common Stock. Accordingly, the USX consolidated financial information should be read in connection with the Marathon Group financial information. - -------------------------------------------------------------------------------- 2. SUMMARY OF PRINCIPAL ACCOUNTING POLICIES PRINCIPLES APPLIED IN CONSOLIDATION - These financial statements include the accounts of the businesses comprising the Marathon Group. The Marathon Group and the U. S. Steel Group financial statements, taken together, comprise all of the accounts included in the USX consolidated financial statements. Investments in unincorporated oil and gas joint ventures, undivided interest pipelines and jointly-owned gas processing plants are consolidated on a pro rata basis. Investments in other entities over which the Marathon Group has significant influence are accounted for using the equity method of accounting and are carried at the Marathon Group's share of net assets plus advances. The proportionate share of income from these equity method investments is included in revenues. Investments in other companies whose stock is publicly traded are carried at market value. The difference between the cost of these investments and market value is recorded as a direct adjustment to stockholders' equity (net of tax). Investments in companies whose stock has no readily determinable fair value are carried at cost. Dividends from these investments are recognized in revenues. Gains or losses from a change in ownership interest of a consolidated subsidiary or an unconsolidated affiliate are recognized in revenues in the period of change. The proportionate share of income represented by the Retained Interest (Note 4) in the Delhi Group prior to June 15, 1995, is included in revenues. In November 1997, USX sold its stock in Delhi Gas Pipeline Corporation and other subsidiaries of USX that comprise all of the Delhi Group (Delhi Companies). USE OF ESTIMATES - Generally accepted accounting principles require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at year-end and the reported amounts of revenues and expenses during the year. CASH AND CASH EQUIVALENTS - Cash and cash equivalents include cash on hand and on deposit and highly liquid debt instruments with maturities generally of three months or less. INVENTORIES - Inventories are carried at lower of cost or market. Cost of inventories is determined primarily under the last-in, first-out (LIFO) method. M-5 DERIVATIVE INSTRUMENTS - The Marathon Group engages in commodity and currency risk management activities within the normal course of its business as an end-user of derivative instruments (Note 25). Management is authorized to manage exposure to price fluctuations related to the purchase, production or sale of crude oil, natural gas, refined products and electricity through the use of a variety of derivative financial and nonfinancial instruments. Derivative financial instruments require settlement in cash and include such instruments as over-the-counter (OTC) commodity swap agreements and OTC commodity options. Derivative nonfinancial instruments require or permit settlement by delivery of commodities and include exchange-traded commodity futures contracts and options. At times, derivative positions are closed, prior to maturity, simultaneous with the underlying physical transaction and the effects are recognized in income accordingly. The Marathon Group's practice does not permit derivative positions to remain open if the underlying physical market risk has been removed. Derivative instruments relating to fixed price sales of equity production are marked-to-market in the current period and the related income effects are included within income from operations. All other changes in the market value of derivative instruments are deferred, including both closed and open positions, and are subsequently recognized in income, as sales or cost of sales, in the same period as the underlying transaction. Premiums on all commodity-based option contracts are initially recorded based on the amount paid or received; the options' market value is subsequently recorded as a receivable or payable, as appropriate. The margin receivable accounts required for open commodity contracts reflect changes in the market prices of the underlying commodity and are settled on a daily basis. Forward currency contracts are used to manage currency risks related to anticipated revenues and operating costs, firm commitments for capital expenditures and existing assets or liabilities denominated in a foreign currency. Gains or losses related to firm commitments are deferred and included with the underlying transaction; all other gains or losses are recognized in income in the current period as sales, cost of sales, interest income or expense, or other income, as appropriate. Net contract values are included in receivables or payables, as appropriate. Recorded deferred gains or losses are reflected within other noncurrent assets or deferred credits and other liabilities. Cash flows from the use of derivative instruments are reported in the same category as the hedged item in the statement of cash flows. EXPLORATION AND DEVELOPMENT - The Marathon Group follows the successful efforts method of accounting for oil and gas exploration and development. GAS BALANCING - The Marathon Group follows the sales method of accounting for gas production imbalances. LONG-LIVED ASSETS - Depreciation and depletion of oil and gas producing properties are computed using predetermined rates based upon estimated proved oil and gas reserves applied on a units-of- production method. Other items of property, plant and equipment are depreciated principally by the straight-line method. When an entire property, major facility or facilities depreciated on an individual basis are sold or otherwise disposed of, any gain or loss is reflected in income. Proceeds from disposal of other facilities depreciated on a group basis are credited to the depreciation reserve with no immediate effect on income. The Marathon Group evaluates impairment of its oil and gas assets primarily on a field-by-field basis. Other assets are evaluated on an individual asset basis or by logical groupings of assets. Assets deemed to be impaired are written down to their fair value, including any related goodwill, using discounted future cash flows and, if available, comparable market values. ENVIRONMENTAL LIABILITIES - The Marathon Group provides for remediation costs and penalties when the responsibility to remediate is probable and the amount of associated costs is reasonably determinable. Generally, the timing of remediation accruals coincides with completion of a feasibility study or the commitment to a formal plan of action. Remediation liabilities are accrued based on estimates of known environmental exposure and could be discounted in certain instances. If recoveries of remediation costs from third parties are probable, a receivable is recorded. Estimated abandonment and dismantlement costs of offshore production platforms are accrued based upon estimated proved oil and gas reserves on a units-of-production method. INSURANCE - The Marathon Group is insured for catastrophic casualty and certain property and business interruption exposures, as well as those risks required to be insured by law or contract. Costs resulting from noninsured losses are charged against income upon occurrence. RECLASSIFICATIONS - Certain reclassifications of prior years' data have been made to conform to 1997 classifications. M-6 - -------------------------------------------------------------------------------- 3. NEW ACCOUNTING STANDARDS The following accounting standards were adopted by USX during 1997: Environmental remediation liabilities - Effective January 1, 1997, USX adopted American Institute of Certified Public Accountants Statement of Position No. 96-1, "Environmental Remediation Liabilities" (SOP 96-1), which provides additional interpretation of existing accounting standards related to recognition, measurement and disclosure of environmental remediation liabilities. As a result of adopting SOP 96-1, the Marathon Group identified additional environmental remediation liabilities of $11 million. Estimated receivables for recoverable costs related to adoption of SOP 96-1 were $4 million. The net unfavorable effect of adoption on the Marathon Group's income from operations at January 1, 1997, was $7 million. Earnings per share USX adopted Statement of Financial Accounting Standards No. 128, "Earnings per Share" (SFAS No. 128). This Statement establishes standards for computing and presenting earnings per share (EPS). SFAS No. 128 requires dual presentation of basic and diluted EPS. Basic EPS excludes dilution and is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if stock options or convertible securities were exercised or converted into common stock. The adoption of SFAS No. 128 did not materially change current and prior years' EPS of the Marathon Group. - -------------------------------------------------------------------------------- 4. CORPORATE ACTIVITIES FINANCIAL ACTIVITIES - As a matter of policy, USX manages most financial activities on a centralized, consolidated basis. Such financial activities include the investment of surplus cash; the issuance, repayment and repurchase of short-term and long-term debt; the issuance, repurchase and redemption of preferred stock; and the issuance and repurchase of common stock. Transactions related primarily to invested cash, short-term and long-term debt (including convertible debt), related net interest and other financial costs, and preferred stock and related dividends are attributed to the Marathon Group, the U. S. Steel Group and, prior to November 1, 1997, the Delhi Group based upon the cash flows of each group for the periods presented and the initial capital structure of each group. Most financing transactions are attributed to and reflected in the financial statements of all groups. See Note 9, for the Marathon Group's portion of USX's financial activities attributed to all groups. However, transactions such as leases, certain collaterized financings, certain indexed debt instruments, financial activities of consolidated entities which are less than wholly owned by USX and transactions related to securities convertible solely into any one class of common stock are or will be specifically attributed to and reflected in their entirety in the financial statements of the group to which they relate. CORPORATE GENERAL AND ADMINISTRATIVE COSTS - Corporate general and administrative costs are allocated to the Marathon Group, the U. S. Steel Group and, prior to November 1, 1997, the Delhi Group based upon utilization or other methods management believes to be reasonable and which consider certain measures of business activities, such as employment, investments and sales. The costs allocated to the Marathon Group were $37 million in 1997 and $30 million in 1996 and 1995, and primarily consist of employment costs including pension effects, professional services, facilities and other related costs associated with corporate activities. COMMON STOCK TRANSACTIONS - The USX Board of Directors, prior to June 15, 1995, had designated 14,003,205 shares of USX - Delhi Group Common Stock (Delhi Stock) to represent 100% of the common stockholders' equity value of USX attributable to the Delhi Group. The Delhi Fraction was the percentage interest in the Delhi Group represented by the shares of Delhi Stock that were outstanding at any particular time and, based on 9,438,391 outstanding shares at June 14, 1995, was approximately 67%. The Marathon Group financial statements reflected a percentage interest in the Delhi Group of approximately 33% (Retained Interest) through June 14, 1995. The financial position, results of operations and cash flows of the Delhi Group were reflected in the financial statements of the Marathon Group only to the extent of the Retained Interest. The shares deemed to represent the Retained Interest were not outstanding shares of Delhi Stock and could not be voted by the Marathon Group. As additional shares of Delhi Stock deemed to represent the Retained Interest were sold, the Retained Interest decreased. When a dividend was paid in respect to the outstanding Delhi Stock, the Marathon Group financial statements were credited, and the Delhi Group financial statements were charged, with the aggregate transaction amount times the quotient of the Retained Interest divided by the Delhi Fraction. On June 15, 1995, USX eliminated the Marathon Group's Retained Interest in the Delhi Group (equivalent to 4,564,814 shares of Delhi Stock). This was accomplished through a reallocation of assets and a corresponding adjustment to debt and equity attributed to the Marathon and Delhi Groups. The reallocation was made at a price of $12.75 per equivalent share of Delhi Stock, or an aggregate of $58 million, resulting in a corresponding reduction of the Marathon Group debt. M-7 INCOME TAXES - All members of the USX affiliated group are included in the consolidated United States federal income tax return filed by USX. Accordingly, the provision for federal income taxes and the related payments or refunds of tax are determined on a consolidated basis. The consolidated provision and the related tax payments or refunds have been reflected in the Marathon Group, the U. S. Steel Group and, prior to November 1, 1997, the Delhi Group financial statements in accordance with USX's tax allocation policy. In general, such policy provides that the consolidated tax provision and related tax payments or refunds are allocated among the Marathon Group, the U. S. Steel Group and, prior to November 1, 1997, the Delhi Group, for group financial statement purposes, based principally upon the financial income, taxable income, credits, preferences and other amounts directly related to the respective groups. For tax provision and settlement purposes, tax benefits resulting from attributes (principally net operating losses and various tax credits), which cannot be utilized by one of the groups on a separate return basis but which can be utilized on a consolidated basis in that year or in a carryback year, are allocated to the group that generated the attributes. To the extent that one of the groups is allocated a consolidated tax attribute which, as a result of expiration or otherwise, is not ultimately utilized on the consolidated tax return, the prior years' allocation of such attribute is adjusted such that the effect of the expiration is borne by the group that generated the attribute. Also, if a tax attribute cannot be utilized on a consolidated basis in the year generated or in a carryback year, the prior years' allocation of such consolidated tax effects is adjusted in a subsequent year to the extent necessary to allocate the tax benefits to the group that would have realized the tax benefits on a separate return basis. As a result, the allocated group amounts of taxes payable or refundable are not necessarily comparable to those that would have resulted if the groups had filed separate tax returns. - -------------------------------------------------------------------------------- 5. REVENUES The items below are included in revenues and costs and expenses, with no effect on income.

M-8 - ------------------------------------------------------------------------------- 7. IMPAIRMENT OF LONG-LIVED ASSETS In 1995, USX adopted Statement of Financial Accounting Standards No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of" (SFAS No. 121). SFAS No. 121 requires that long-lived assets, including related goodwill, be reviewed for impairment and written down to fair value whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Adoption of SFAS No. 121 resulted in an impairment charge included in 1995 costs and expenses of $659 million. The impaired assets primarily included certain domestic and international oil and gas properties, an idled refinery and related goodwill. The Marathon Group assessed impairment of its oil and gas properties based primarily on a field-by-field approach. The predominant method used to determine fair value was a discounted cash flow approach and where available, comparable market values were used. The impairment provision reduced capitalized costs of oil and gas properties by $533 million. In addition, the Indianapolis, Indiana refinery, which was temporarily idled in October 1993, was impaired by $126 million, including related goodwill. The impairment was based on a discounted cash flow approach and comparable market values. - ------------------------------------------------------------------------------- 8. EXTRAORDINARY LOSS On December 30, 1996, USX irrevocably called for redemption on January 30, 1997, $120 million of debt, resulting in a 1996 extraordinary loss to the Marathon Group of $7 million, net of a $4 million income tax benefit. In 1995, USX extinguished $553 million of debt prior to maturity, which resulted in an extraordinary loss to the Marathon Group of $5 million, net of a $3 million income tax benefit. - ------------------------------------------------------------------------------- 9.

DIVIDENDS In accordance with the USX Certificate of Incorporation, dividends on the Marathon Stock and Steel Stock are limited to the legally available funds of USX. Net losses of either Group, as well as dividends and distributions on any class of USX Common Stock or series of preferred stock and repurchases of any class of USX Common Stock or series of preferred stock at prices in excess of par or stated value, will reduce the funds of USX legally available for payment of dividends on both classes of Common Stock. Subject to this limitation, the Board of Directors intends to declare and pay dividends on the Marathon Stock based on the financial condition and results of operation of the Marathon Group, although it has no obligation under Delaware law to do so. In making its dividend decisions with respect to Marathon Stock, the Board of Directors considers among other things, the long-term earnings and cash flow capabilities of the Marathon Group as well as the dividend policies of similar publicly traded energy companies. - -------------------------------------------------------------------------------- 14. STOCK-BASED COMPENSATION PLANS AND STOCKHOLDER RIGHTS PLAN USX Stock-Based Compensation Plans and Stockholder Rights Plan are discussed in Note 21, and Note 23, respectively, to the USX consolidated financial statements. In 1996, USX adopted SFAS No. 123, Accounting for Stock- Based Compensation and elected to continue to follow the accounting provisions of APB No. 25, as discussed in Note 2, to the USX consolidated financial statements. The Marathon Group's actual stock-based compensation expense was $20 million in 1997, $6 million in 1996 and $2 million in 1995. Incremental compensation expense, as determined under SFAS No. 123, was not material ($.02 or less per share for all years presented). Therefore, pro forma net income and earnings per share data have been omitted. M-11 - -------------------------------------------------------------------------------- 15. PENSIONS The Marathon Group has noncontributory defined benefit plans covering substantially all employees. Benefits under these plans are based primarily upon years of service and the highest three years earnings during the last ten years before retirement. Certain subsidiaries provide benefits for employees covered by other plans based primarily upon employees' service and career earnings. The funding policy for all plans provides that payments to the pension trusts shall be equal to the minimum funding requirements of ERISA plus such additional amounts as may be approved. PENSION COST (CREDIT) - The defined benefit cost for major plans for 1997, 1996 and 1995 was determined assuming an expected long- term rate of return on plan assets of 9.5%, 10% and 10%, respectively, and was as follows: (In millions) 1997 1996 1995 -------------------------------------------------------------------------------------- Major plans: Cost of benefits earned during the period $ 31 $ 35 $ 26 Interest cost on projected benefit obligation (7.5% for 1997; 7% for 1996; and 8% for 1995) 45 45 41 Return on assets - actual return (217) (139) (197) - deferred gain 132 55 116 Net amortization of unrecognized gains (3) (3) (4) ------- ------- ------- Total major plans (12) (7) (18) Other plans 4 4 4 ------- ------- ------- Total periodic pension credit (8) (3) (14) Curtailment losses - - 2 ------- ------- ------- Total pension credit $ (8) $ (3) $ (12) -------------------------------------------------------------------------------------- FUNDS' STATUS - The assumed discount rate used to measure the benefit obligations of major plans was 7% at December 31, 1997, and 7.5% at December 31, 1996. The assumed rate of future increases in compensation levels was 5% at both year-ends. The following table sets forth the plans' funded status and the amounts reported in the Marathon Group's balance sheet: (In millions) December 31 1997 1996 ------------------------------------------------------------------------------------------- Reconciliation of funds' status to reported amounts: Projected benefit obligation (PBO)/(a)/ $ (771) $ (627) Plan assets at fair market value/(b)/ 1,150 989 -------- -------- Assets in excess of PBO/(c)/ 379 362 Unrecognized net gain from transition (40) (45) Unrecognized prior service cost 45 8 Unrecognized net gain (115) (65) Additional minimum liability/(d)/ (14) (11) -------- -------- Net pension asset included in balance sheet $ 255 $ 249 -------------------------------------------------------------------------------------------- /(a)/ PBO includes: Accumulated benefit obligation (ABO) $ (562) $ (479) Vested benefit obligation (496) (424) /(b)/ Types of assets held: Stocks of other corporations 70% 70% U.S. Government securities 9% 10% Corporate debt instruments and other 21% 20% /(c)/ Includes several small plans that have ABOs in excess of plan assets: PBO $ (82) $ (68) Plan assets 24 18 -------- -------- PBO in excess of plan assets $ (58) $ (50) /(d)/ Additional minimum liability recorded was offset by the following: Intangible asset $ 3 $ 3 Stockholders' equity adjustment - net of deferred income tax 7 5 -------------------------------------------------------------------------------------------- M-12 - -------------------------------------------------------------------------------- 16. POSTRETIREMENT BENEFITS OTHER THAN PENSIONS The Marathon Group has defined benefit retiree health and life insurance plans covering most employees upon their retirement. Health benefits are provided, for the most part, through comprehensive hospital, surgical and major medical benefit provisions subject to various cost sharing features. Life insurance benefits are provided to nonunion and most union represented retiree beneficiaries primarily based on employees' annual base salary at retirement. Benefits have not been prefunded. POSTRETIREMENT BENEFIT COST - Postretirement benefit cost for defined benefit plans for 1997, 1996 and 1995 was determined assuming discount rates of 7.5%, 7% and 8%, respectively, and was as follows: (In millions) 1997 1996 1995 ----------------------------------------------------------------------------------------- Cost of benefits earned during the period $ 6 $ 8 $ 7 Interest on accumulated postretirement benefit obligation (APBO) 22 23 22 Amortization of unrecognized gains (3) (3) (3) ----- ----- ----- Total postretirement benefit cost $ 25 $ 28 $ 26 ----------------------------------------------------------------------------------------- OBLIGATIONS - The following table sets forth the plans' obligations and the amounts reported in the Marathon Group's balance sheet: (In millions) December 31 1997 1996 ------------------------------------------------------------------------------------- Reconciliation of APBO to reported amounts: APBO attributable to: Retirees $ 196 $ 162 Fully eligible plan participants 72 53 Other active plan participants 113 84 ----- ----- Total APBO 381 299 Unrecognized net loss (73) (4) Unrecognized prior service cost 18 21 ----- ----- Accrued liability included in balance sheet $ 326 $ 316 ------------------------------------------------------------------------------------- The assumed discount rate used to measure the APBO was 7% and 7.5% at December 31, 1997, and December 31, 1996, respectively. The assumed rate of future increases in compensation levels was 5% at both year-ends. The weighted average health care cost trend rate in 1998 is approximately 8%, gradually declining to an ultimate rate in 2004 of approximately 5%. A one percentage point increase in the assumed health care cost trend rates for each future year would have increased the aggregate of the service and interest cost components of the 1997 net periodic postretirement benefit cost by $5 million and would have increased the APBO as of December 31, 1997, by $56 million. - -------------------------------------------------------------------------------- 17.

M-13 - -------------------------------------------------------------------------------- 18. INCOME TAXES Income tax provisions and related assets and liabilities attributed to the Marathon Group are determined in accordance with the USX group tax allocation policy (Note 4). Provisions (credits) for estimated income taxes were: 1997 1996 1995 ------------------------------ --------------------------- --------------------------- (In millions) Current Deferred Total Current Deferred Total Current Deferred Total --------------------------------------------------------------------------------------------------------------------- Federal $171 $ (5) $166 $193 $ 13 $ 206 $ 72 $(221) $(149) State and local 3 7 10 12 9 21 10 (14) (4) Foreign 12 28 40 11 82 93 15 31 46 ---- ----- ---- ---- ----- ----- ----- ----- ----- Total $186 $ 30 $216 $216 $ 104 $ 320 $ 97 $(204) $(107) --------------------------------------------------------------------------------------------------------------------- A reconciliation of federal statutory tax rate (35%) to total provisions (credits) follows: (In millions) 1997 1996 1995 -------------------------------------------------------------------------------------------------------------------- Statutory rate applied to income (loss) before income taxes $ 235 $ 347 $ (67) State and local income taxes after federal income tax effects 6 14 (3) Effects of foreign operations, including foreign tax credits (8) (14) (36)/(a)/ Effects of partially-owned companies (6) (10) (7) Dispositions of subsidiary investments - (8) (6) Credits other than foreign tax credits (9) (8) (1) Nondeductible business and amortization expenses 3 3 10 Adjustment of prior years' income taxes (4) (6) (1) Adjustment of valuation allowances (4) - 4 Other 3 2 - ----- ----- ----- Total provisions (credits) $ 216 $ 320 $(107) -------------------------------------------------------------------------------------------------------------------- /(a)/ Includes incremental tax benefits of $44 million resulting from USX's election to credit, rather than deduct, certain foreign income taxes for federal income tax purposes. Deferred tax assets and liabilities resulted from the following: (In millions) December 31 1997 1996 ---------------------------------------------------------------------------------------------------------------------- Deferred tax assets: Minimum tax credit carryforwards $ 42 $ 110 State tax loss carryforwards (expiring in 1998 through 2012) 52 40 Foreign tax loss carryforwards (portion of which expire in 1998 through 2012) 483 519 Employee benefits 172 158 Expected federal benefit for: Crediting certain foreign deferred income taxes 249 216 Deducting state and other foreign deferred income taxes 53 51 Contingency and other accruals 148 116 Other 54 56 Valuation allowances (311) (325) ------ ------ Total deferred tax assets/(a)/ 942 941 ------ ------ Deferred tax liabilities: Property, plant and equipment 1,820 1,685 Inventory 199 306 Prepaid pensions 129 121 Other 114 118 ------ ----- Total deferred tax liabilities 2,262 2,230 ------ ----- Net deferred tax liabilities $1,320 $1,289 ---------------------------------------------------------------------------------------------------------------------- /(a)/ USX expects to generate sufficient future taxable income to realize the benefit of the Marathon Group's deferred tax assets. In addition, the ability to realize the benefit of foreign tax credits is based upon certain assumptions concerning future operating conditions (particularly as related to prevailing oil prices), income generated from foreign sources and USX's tax profile in the years that such credits may be claimed. The consolidated tax returns of USX for the years 1990 through 1994 are under various stages of audit and administrative review by the IRS. USX believes it has made adequate provision for income taxes and interest which may become payable for years not yet settled. Pretax income (loss) included $250 million, $341 million and $(50) million attributable to foreign sources in 1997, 1996 and 1995, respectively. Undistributed earnings of consolidated foreign subsidiaries at December 31, 1997, amounted to $108 million. No provision for deferred U.S. income taxes has been made because the Marathon Group intends to permanently reinvest such earnings in its foreign operations. If such earnings were not permanently reinvested, a deferred tax liability of $38 million would have been required.

INVESTMENTS AND LONG-TERM RECEIVABLES (In millions) December 31 1997 1996 ---------------------------------------------------------------------------- Equity method investments $ 366 $ 135 Other investments 32 31 Deposit in property exchange trusts - 98 Receivables due after one year 49 34 Forward currency contracts - 12 Other 8 1 ----- ----- Total $ 455 $ 311 ---------------------------------------------------------------------------- The following represents summarized financial information of affiliates accounted for by the equity method of accounting, except for the Retained Interest in the Delhi Group: (In millions) 1997 1996 1995 --------------------------------------------------------------- Income data - year: Revenues $ 562 $ 405 $ 255 Operating income 114 95 77 Net income 52 53 24 --------------------------------------------------------------- Balance sheet data - December 31: Current assets $ 170 $ 146 Noncurrent assets 1,470 1,150 Current liabilities 236 198 Noncurrent liabilities 721 737 --------------------------------------------------------------- Dividends and partnership distributions received from equity affiliates were $21 million in 1997, $24 million in 1996 and $14 million in 1995. Marathon Group purchases from equity affiliates totaled $37 million, $49 million and $52 million in 1997, 1996 and 1995, respectively. Marathon Group sales to equity affiliates were $10 million in 1997, $6 million in 1996 and immaterial in 1995. Summarized financial information of the Delhi Group, which was accounted for by the equity method of accounting follows: (In millions) 1995/(a)/ ------------------------------------------------------ Income data for the period: Revenues $ 276 Operating income 14 Net income 7 ----------------------------------------------------- /(a)/ Retained Interest in the Delhi Group was eliminated on June 15, 1995. 20.

The LIFO method accounted for 91% and 94% of total inventory value at December 31, 1997, and December 31, 1996, respectively. The inventory market valuation reserve reflects the extent that the recorded LIFO cost basis of crude oil and refined products inventories exceeds net realizable value. The reserve is decreased to reflect increases in market prices and inventory turnover and increased to reflect decreases in market prices. Changes in the inventory market valuation reserve result in noncash charges or credits to costs and expenses. M-15 - -------------------------------------------------------------------------------- 21. INTERGROUP TRANSACTIONS SALES AND PURCHASES - Marathon Group sales to other groups totaled $105 million, $87 million and $54 million in 1997, 1996 and 1995, respectively. Marathon Group purchases from the Delhi Group totaled $18 million in 1997, $9 million in 1996 and $6 million in 1995. At December 31, 1997 and 1996, Marathon Group receivables included $3 million and $19 million, respectively, related to transactions with other groups. Marathon Group accounts payable included none at December 31, 1997, and $2 million at December 31, 1996, related to transactions with the Delhi Group. These transactions were conducted on an arm's-length basis. After October 31, 1997, transactions with the Delhi Companies were treated as third-party transactions. INCOME TAXES RECEIVABLE FROM/PAYABLE TO OTHER GROUPS - At December 31, 1997 and 1996, amounts receivable from/payable to other groups for income taxes were included in the balance sheet as follows: (In millions) December 31 1997 1996 ------------------------------------------------------------------------------------------ Current: Receivables $ 2 $ 1 Accounts payable 22 30 Noncurrent: Deferred credits and other liabilities 97 83 ------------------------------------------------------------------------------------------ These amounts have been determined in accordance with the tax allocation policy described in Note 4. Amounts classified as current are settled in cash in the year succeeding that in which such amounts are accrued. Noncurrent amounts represent estimates of intergroup tax effects of certain issues for years that are still under various stages of audit and administrative review. Such tax effects are not settled among the groups until the audit of those respective tax years is closed. The amounts ultimately settled for open tax years will be different than recorded noncurrent amounts based on the final resolution of all of the audit issues for those years. - -------------------------------------------------------------------------------- 22.

SALES OF RECEIVABLES The Marathon Group, prior to December 1997, participated in an agreement (the program) to sell an undivided interest in certain accounts receivable. At December 31, 1997, the amount sold under the program that had not been collected was zero, since the program was terminated in December 1997. The amount sold under the program averaged $314 million in 1997, $340 million in 1996 and $361 million in 1995. - -------------------------------------------------------------------------------- 24. INCOME PER COMMON SHARE The method of calculating net income per share for the Marathon Stock, the Steel Stock and, prior to November 1, 1997, the Delhi Stock reflects the USX Board of Directors' intent that the separately reported earnings and surplus of the Marathon Group, the U. S. Steel Group and the Delhi Group, as determined consistent with the USX Certificate of Incorporation, are available for payment of dividends to the respective classes of stock, although legally available funds and liquidation preferences of these classes of stock do not necessarily correspond with these amounts. Basic net income (loss) per share is calculated by adjusting net income (loss) for dividend requirements of preferred stock and is based on the weighted average number of common shares outstanding. Diluted net income (loss) per share assumes conversion of convertible securities for the applicable periods outstanding and assumes exercise of stock options, provided in each case, the effect is not antidilutive. 1997 1996 1995 ------------------ -------------------- -------------------- COMPUTATION OF INCOME PER SHARE BASIC DILUTED Basic Diluted Basic Diluted ------------------------------- -------- -------- --------- --------- --------- --------- Net income (loss) (millions): Income (loss) before extraordinary loss $ 456 $ 456 $ 671 $ 671 $ (83) $ (83) Dividends on preferred stock - - - - (4) (4) Extraordinary loss - - (7) (7) (5) (5) -------- -------- -------- -------- -------- -------- Net income (loss) applicable to Marathon Stock 456 456 664 664 (92) (92) Effect of dilutive securities - Convertible debentures - 3 - 14 - - -------- -------- -------- -------- -------- -------- Net income (loss) assuming conversions $ 456 $ 459 $ 664 $ 678 $ (92) $ (92) ======== ======== ======== ======== ======== ======== Shares of common stock outstanding (thousands): Average number of common shares outstanding 288,038 288,038 287,460 287,460 287,271 287,271 Effect of dilutive securities: Convertible debentures - 1,936 - 8,975 - - Stock options - 546 - 133 - - -------- -------- -------- -------- -------- -------- Average common shares and dilutive effect 288,038 290,520 287,460 296,568 287,271 287,271 -------- -------- -------- -------- -------- -------- Per share: Income (loss) before extraordinary loss $ 1.59 $ 1.58 $ 2.33 $ 2.31 $ (.31) $ (.31) Extraordinary loss - - (.02) (.02) (.02) (.02) -------- -------- -------- -------- -------- -------- Net income (loss) $ 1.59 $ 1.58 $ 2.31 $ 2.29 $ (.33) $ (.33) ======== ======== ======== ======== ======== ======== - -------------------------------------------------------------------------------- 25. DERIVATIVE INSTRUMENTS The Marathon Group uses commodity-based derivative instruments to manage exposure to price fluctuations related to the anticipated purchase or production and sale of crude oil, natural gas, refined products and electricity. The derivative instruments used, as a part of an overall risk management program, include exchange-traded futures contracts and options, and instruments which require settlement in cash such as OTC commodity swaps and OTC options. While risk management activities generally reduce market risk exposure due to unfavorable commodity price changes for raw material purchases and products sold, such activities can also encompass strategies which assume certain price risk in isolated transactions. USX has used forward currency contracts to hedge foreign denominated debt, a portion of which has been attributed to the Marathon Group. The Marathon Group remains at risk for possible changes in the market value of the derivative instrument; however, such risk should be mitigated by price changes in the underlying hedged item. The Marathon Group is also exposed to credit risk in the event of nonperformance by counterparties. The credit worthiness of counterparties is subject to continuing review, including the use of master netting agreements to the extent practical, and full performance is anticipated. M-17 The following table sets forth quantitative information by class of derivative instrument: FAIR CARRYING RECORDED VALUE AMOUNT DEFERRED AGGREGATE ASSETS ASSETS GAIN OR CONTRACT (In millions) (LIABILITIES) /(A)/ (LIABILITIES) (LOSS) VALUES /(B)/ ----------------------------------------------------------------------------------------------------- DECEMBER 31, 1997: Exchange-traded commodity futures $ - $ - $ - $ 30 Exchange-traded commodity options 1 /(c)/ 1 2 129 OTC commodity swaps /(d)/ (2) /(e)/ (2) (3) 30 OTC commodity options - - - 6 ------ ------- ------ -------- Total commodities $ (1) $ (1) $ (1) $ 195 ------ ------- ------ -------- Forward currency contract /(f)/: - receivable $ 10 $ 9 $ - $ 52 - payable (1) (1) (1) 5 ------ ------- ------ -------- Total currencies $ 9 $ 8 $ (1) $ 57 ----------------------------------------------------------------------------------------------------- December 31, 1996: Exchange-traded commodity futures $ - $ - $ (2) $ 38 Exchange-traded commodity options (1) /(c)/ (1) (2) 251 OTC commodity swaps (3) /(e)/ (2) - 32 OTC commodity options (7) (7) (1) 80 ------ ------- ------ -------- Total commodities $ (11) $ (10) $ (5) $ 401 ------ ------- ------ -------- Forward currency contract: - receivable $ 14 $ 12 $ - $ 43 - payable (1) (1) (1) 7 ------ ------- ------ -------- Total currencies $ 13 $ 11 $ (1) $ 50 ----------------------------------------------------------------------------------------------------- /(a)/ The fair value amounts for OTC positions are based on various indices or dealer quotes. The fair value amounts for currency contracts are based on dealer quotes of forward prices covering the remaining duration of the foreign exchange contract. The exchange-traded futures contracts and certain option contracts do not have a corresponding fair value since changes in the market prices are settled on a daily basis. /(b)/ Contract or notional amounts do not quantify risk exposure, but are used in the calculation of cash settlements under the contracts. The contract or notional amounts do not reflect the extent to which positions may offset one another. /(c)/ Includes fair values as of December 31, 1997 and 1996, for assets of $3 million and $1 million and liabilities of $(2) million and $(2) million, respectively. /(d)/ The OTC swap arrangements vary in duration with certain contracts extending into mid 2000. /(e)/ Includes fair values as of December 31, 1997 and 1996, for assets of $1 million and $1 million and liabilities of $(3) million and $(4) million, respectively. /(f)/ The forward currency contract matures in 1998. - -------------------------------------------------------------------------------- 26. FAIR VALUE OF FINANCIAL INSTRUMENTS Fair value of the financial instruments disclosed herein is not necessarily representative of the amount that could be realized or settled, nor does the fair value amount consider the tax consequences of realization or settlement. The following table summarizes financial instruments, excluding derivative financial instruments disclosed in Note 25, by individual balance sheet account. As described in Note 4, the Marathon Group's specifically attributed financial instruments and the Marathon Group's portion of USX's financial instruments attributed to all groups are as follows: 1997 1996 ------------------------ ---------------------- FAIR CARRYING Fair Carrying (In millions) December 31 VALUE AMOUNT Value Amount ---------------------------------------------------------------------------------------------------------- FINANCIAL ASSETS: Cash and cash equivalents $ 36 $ 36 $ 32 $ 32 Receivables 856 856 613 613 Investments and long-term receivables 143 86 204 163 ------ ------ ------ ------ Total financial assets $1,035 $ 978 $ 849 $ 808 ---------------------------------------------------------------------------------------------------------- FINANCIAL LIABILITIES: Notes payable $ 108 $ 108 $ 59 $ 59 Accounts payable 1,348 1,348 1,385 1,385 Accrued interest 84 84 75 75 Long-term debt (including amounts due within one year) 3,198 2,869 3,062 2,882 Preferred stock of subsidiary 187 184 185 182 ------ ------ ------ ------ Total financial liabilities $4,925 $4,593 $4,766 $4,583 ---------------------------------------------------------------------------------------------------------- M-18 Fair value of financial instruments classified as current assets or liabilities approximates carrying value due to the short-term maturity of the instruments. Fair value of investments and long-term receivables was based on discounted cash flows or other specific instrument analysis. Fair value of preferred stock of subsidiary was based on market prices. Fair value of long-term debt instruments was based on market prices where available or current borrowing rates available for financings with similar terms and maturities. The Marathon Group's unrecognized financial instruments consist of accounts receivables sold and financial guarantees. It is not practicable to estimate the fair value of these forms of financial instrument obligations because there are no quoted market prices for transactions which are similar in nature. For details relating to sales of receivables see Note 23, and for details relating to financial guarantees see Note 27. - -------------------------------------------------------------------------------- 27. CONTINGENCIES AND COMMITMENTS USX is the subject of, or party to, a number of pending or threatened legal actions, contingencies and commitments relating to the Marathon Group involving a variety of matters, including laws and regulations relating to the environment. Certain of these matters are discussed below. The ultimate resolution of these contingencies could, individually or in the aggregate, be material to the Marathon Group financial statements. However, management believes that USX will remain a viable and competitive enterprise even though it is possible that these contingencies could be resolved unfavorably to the Marathon Group. ENVIRONMENTAL MATTERS - The Marathon Group is subject to federal, state, local and foreign laws and regulations relating to the environment. These laws generally provide for control of pollutants released into the environment and require responsible parties to undertake remediation of hazardous waste disposal sites. Penalties may be imposed for noncompliance. At December 31, 1997, and December 31, 1996, accrued liabilities for remediation totaled $52 million and $37 million, respectively. It is not presently possible to estimate the ultimate amount of all remediation costs that might be incurred or the penalties that may be imposed. Receivables for recoverable costs from certain states, under programs to assist companies in cleanup efforts related to underground storage tanks at retail marketing outlets, were $42 million at December 31, 1997, and $23 million at December 31, 1996. For a number of years, the Marathon Group has made substantial capital expenditures to bring existing facilities into compliance with various laws relating to the environment. In 1997 and 1996, such capital expenditures totaled $81 million and $66 million, respectively. The Marathon Group anticipates making additional such expenditures in the future; however, the exact amounts and timing of such expenditures are uncertain because of the continuing evolution of specific regulatory requirements. At December 31, 1997, and December 31, 1996, accrued liabilities for platform abandonment and dismantlement totaled $128 million and $118 million, respectively. GUARANTEES - Guarantees by USX and its consolidated subsidiaries of the liabilities of affiliated entities of the Marathon Group totaled $23 million and $46 million at December 31, 1997, and December 31, 1996, respectively. As of December 31, 1997, the largest guarantee for a single affiliate was $23 million. At December 31, 1997, and December 31, 1996, the Marathon Group's pro rata share of obligations of LOOP LLC and various pipeline affiliates secured by throughput and deficiency agreements totaled $165 million and $176 million, respectively. Under the agreements, the Marathon Group is required to advance funds if the affiliates are unable to service debt. Any such advances are prepayments of future transportation charges. COMMITMENTS - At December 31, 1997, and December 31, 1996, contract commitments for the Marathon Group's capital expenditures for property, plant and equipment totaled $268 million and $388 million, respectively. M-19 - -------------------------------------------------------------------------------- 28. SUBSEQUENT EVENT - BUSINESS COMBINATIONS On December 12, 1997, the Marathon Group and Ashland Inc. (Ashland) signed definitive agreements to combine the major elements of their refining, marketing and transportation (RM&T) operations. Pursuant to those agreements, on January 1, 1998, the Marathon Group transferred certain RM&T net assets to a new consolidated subsidiary, which was named Marathon Ashland Petroleum LLC (MAP). Also on January 1, 1998, the Marathon Group acquired certain RM&T net assets from Ashland in exchange for a 38% interest in MAP. The acquisition will be accounted for under the purchase method of accounting. The purchase price was determined to be $1.9 billion, based upon an external valuation. The change in the Marathon Group's ownership interest in MAP resulted in a change in interest gain which will be recognized in the first quarter 1998. In connection with the formation of MAP, the Marathon Group and Ashland entered into a Limited Liability Company Agreement dated January 1, 1998 (the LLC Agreement). The LLC Agreement provides for an initial term of MAP expiring on December 31, 2022 (25 years from its formation). The term will automatically be extended for ten-year periods, unless a termination notice is given by either party. Also in connection with the formation of MAP, the parties entered into a Put/Call, Registration Rights and Standstill Agreement (the Put/Call Agreement). The Put/Call Agreement provides that at any time after December 31, 2004, Ashland will have the right to sell to the Marathon Group all of Ashland's ownership interest in MAP, for an amount in cash and/or the Marathon Oil Company or USX debt or equity securities equal to the product of 85% (90% if equity securities are used) of the fair market value of MAP at that time, multiplied by Ashland's percentage interest in MAP. Payment could be made at closing, or at the Marathon Group's option, in three equal annual installments, the first of which would be payable at closing. At any time after December 31, 2004, the Marathon Group will have the right to purchase all of Ashland's ownership interests in MAP, for an amount in cash equal to the product of 115% of the fair market value of MAP at that time, multiplied by Ashland's percentage interest in MAP. The following unaudited pro forma data for the Marathon Group includes the results of operations for the Ashland RM&T net assets, giving effect to the acquisition as if it had been consummated at the beginning of the year presented. The pro forma data is based on historical information and does not necessarily reflect the actual results that would have occurred nor is it necessarily indicative of future results of operations.

M-24 Management's Discussion and Analysis The Marathon Group includes Marathon Oil Company ("Marathon") and certain other subsidiaries of USX Corporation ("USX"), which are engaged in worldwide exploration, production, transportation and marketing of crude oil and natural gas; domestic refining, marketing and transportation of petroleum products; and power generation. Effective January 1, 1998, the USX - Marathon Group and Ashland Inc. formed a new refining, marketing and transportation company, Marathon Ashland Petroleum LLC ("MAP"). For further discussion of MAP, see Note 28 to the Marathon Group Financial Statements and Management's Discussion and Analysis of Operations - Outlook herein. Management's Discussion and Analysis should be read in conjunction with the Marathon Group's Financial Statements and Notes to Financial Statements. During 1997, the Marathon Group's financial performance was primarily led by strong refined product margins, which significantly offset the unfavorable effects of lower worldwide liquid hydrocarbon prices and volumes. In addition, Marathon increased its 1997 capital and investment expenditures by $507 million, or 66%, from 1996 levels, substantially funding its spending with cash provided by operating activities. Certain sections of Management's Discussion and Analysis include forward-looking statements concerning trends or events potentially affecting the businesses of the Marathon Group. These statements typically contain words such as "anticipates", "believes", "estimates", "expects" or similar words indicating that future outcomes are uncertain. In accordance with "safe harbor" provisions of the Private Securities Litigation Reform Act of 1995, these statements are accompanied by cautionary language identifying important factors, though not necessarily all such factors, that could cause future outcomes to differ materially from those set forth in forward-looking statements. For additional risk factors affecting the businesses of the Marathon Group, see Supplementary Data - Disclosures About Forward-Looking Statements in USX's 1997 Form 10-K. MANAGEMENT'S DISCUSSION AND ANALYSIS OF INCOME REVENUES for each of the last three years are summarized in the following table: (Dollars in millions) 1997 1996 1995 ----------------------------------------------------------------------------------- Refined products $ 7,012 $ 7,132 $ 6,127 Merchandise 1,045 1,000 941 Liquid hydrocarbons 941 1,111 881 Natural gas 1,331 1,194 950 Transportation and other/(a)/(c)/ 253 277 239 -------- -------- -------- Subtotal 10,582 10,714 9,138 -------- -------- -------- Matching buy/sell transactions/(b)/ 2,436 2,912 2,067 Excise taxes/(b)/ 2,736 2,768 2,708 -------- -------- -------- Total revenues/(c)/ $ 15,754 $ 16,394 $ 13,913 ----------------------------------------------------------------------------------- /(a)/ Includes dividend and affiliate income, net gains on disposal of assets and other income. /(b)/ Included in both revenues and operating costs, resulting in no effect on income. /(c)/ Amounts in 1996 and 1995 were reclassified in 1997 to include dividend and affiliate income and other income, and to conform to other 1997 classifications. Revenues (excluding matching buy/sell transactions and excise taxes) decreased by $132 million in 1997 from 1996 and increased by $1,576 million in 1996 from 1995. The decrease in 1997 mainly reflected lower average refined product prices and lower worldwide liquid hydrocarbon prices and volumes, partly offset by increased volumes of refined products and higher domestic natural gas volumes and prices. The increase in 1996 primarily resulted from higher average refined product, worldwide liquid hydrocarbon and natural gas prices, partially offset by lower worldwide liquid hydrocarbon volumes. M-25 Management's Discussion and Analysis CONTINUED INCOME FROM OPERATIONS and certain items included in income from operations for each of the last three years are summarized in the following table: (Dollars in millions) 1997 1996 1995 -------------------------------------------------------------------------------------------------- Income from operations/(a)/ $ 932 $ 1,296 $ 147 Less: Certain favorable (unfavorable) items IMV reserve adjustment/(b)/ (284) 209 70 Net gains on certain asset sales/(c)/ - 35 - Charges for withdrawal from MPA/(d)/ - (10) - Certain state tax adjustments/(e)/ - (11) - Impairment of long-lived assets/(f)/ - - (659) Expected environmental remediation recoveries/(g)/ - - 15 ------- ------- ------- Subtotal (284) 223 (574) ------- ------- ------- Income from operations excluding above items $ 1,216 $ 1,073 $ 721 -------------------------------------------------------------------------------------------------- /(a)/ Consists of operating income, dividend and affiliate income, net gains on disposal of investments and other income. Amounts for 1996 and 1995 were reclassified in 1997 to include dividend and affiliate income and other income, and to conform to other 1997 classifications. See Note 9 to the Consolidated Financial Statements for a discussion of operating income. /(b)/ The inventory market valuation ("IMV") reserve reflects the extent to which the recorded LIFO cost basis of crude oil and refined products inventories exceeds net realizable value. For additional details of this noncash adjustment, see discussion below. /(c)/ Includes net gains on sales of interests in a domestic pipeline company and certain production properties. /(d)/ Marine Preservation Association ("MPA") is a non-profit oil spill response group. /(e)/ Accrual of domestic production taxes for prior years. /(f)/ Related to adoption of Statement of Financial Accounting Standards No. 121 - "Accounting for the Impairment of Long- Lived Assets and for Long-Lived Assets to be Disposed Of " ("SFAS No. 121"). /(g)/ Expected recoveries from state governments of expenditures related to underground storage tanks at retail marketing outlets. Adjusted income from operations increased by $143 million in 1997 from 1996 and by $352 million in 1996 from 1995. The improvement in 1997 was primarily due to higher average refined product margins and higher worldwide natural gas prices, partially offset by reduced worldwide liquid hydrocarbon production and prices, higher worldwide exploration expense and increased administrative expenses. The improvement in 1996 from 1995 was primarily due to higher worldwide liquid hydrocarbon and natural gas prices, reduced depreciation, depletion and amortization ("DD&A") expense, resulting mainly from the fourth quarter 1995 adoption of SFAS No. 121 and property sales, and increased worldwide volumes of natural gas. These favorable effects were partially offset by lower worldwide liquid hydrocarbon volumes, net losses on production hedging activities (primarily occurring in the fourth quarter of 1996) and lower refined product margins. For additional details, see Management's Discussion and Analysis of Operations. With respect to the IMV reserve adjustment, when U. S. Steel Corporation acquired Marathon Oil Company in March 1982, crude oil and refined product prices were at historically high levels. In applying the purchase method of accounting, Marathon's crude oil and refined product inventories were revalued by reference to current prices at the time of acquisition. This became the new LIFO cost basis of the inventories, which has been maintained since the 1982 acquisition. Generally accepted accounting principles require that inventories be valued at lower of cost or market. Accordingly, Marathon has established an IMV reserve to reduce the LIFO cost basis of these inventories on a quarterly basis, to the extent necessary, to current market value. Adjustments to the IMV reserve result in noncash charges or credits to income from operations. These adjustments affect the comparability of financial results from period to period as well as comparisons with other energy companies, which may not have such adjustments. The IMV reserve adjustments have been separately reported, on a consistent basis, as a component of operating results and separately identified in management's discussion of operations. Commodity prices have fluctuated widely and, since 1986, have generally remained below prices that existed at the time of the 1982 acquisition, resulting in periodic adjustments to the LIFO cost basis of the inventories. At December 31, 1997, LIFO cost exceeded market prices by $284 million, resulting in a corresponding charge to income from operations for total year 1997. During 1996 and 1995, favorable market price movements resulted in credits to income from operations of $209 million M-26 Management's Discussion and Analysis CONTINUED and $70 million, respectively. The $493 million variance in income from operations between 1997 and 1996 for the IMV reserve adjustments (and $139 million variance between 1996 and 1995) affects the comparability of reported financial results. In management's opinion, the Marathon Group's operating performance should be evaluated exclusive of the IMV reserve adjustments, which management believes provides a more indicative view of the profit and cash flow performance of the Group. NET INTEREST AND OTHER FINANCIAL COSTS decreased by $45 million in 1997 from 1996, following a decrease of $32 million in 1996 from 1995. The decrease in both periods was mainly due to lower average debt levels, while 1997 also reflected an increase in capitalized interest on worldwide exploration and production projects. For additional details, see Note 6 to the Marathon Group Financial Statements. The CREDIT FOR ESTIMATED INCOME TAXES in 1995 included incremental tax benefits of $44 million resulting from USX's election to credit, rather than deduct, foreign income taxes for U.S. federal income tax purposes. For reconciliation of the federal statutory tax rate to total provisions (credits), see Note 18 to the Marathon Group Financial Statements. An EXTRAORDINARY LOSS on extinguishment of debt of $7 million in 1996 and $5 million in 1995 represents the portion of the loss on early extinguishment of USX debt attributed to the Marathon Group. For additional information, see Note 8 to the Marathon Group Financial Statements. NET INCOME decreased by $208 million in 1997 from 1996, following an increase of $752 million in 1996 from 1995. Excluding the aftertax effects of the IMV reserve adjustment and other special items, financial results increased by $106 million in 1997 from 1996 and by $300 million in 1996 from 1995, primarily reflecting the factors discussed above. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION, CASH FLOWS AND LIQUIDITY CURRENT ASSETS declined $28 million from year-end 1996, primarily due to a decrease in inventories, offset by an increase in receivables. The reduced inventory values were due mainly to lower year-end refined product prices, which resulted in an IMV reserve of $284 million. The increase in receivables was primarily due to the termination of the accounts receivable sales program (see Note 23 to the Marathon Group Financial Statements), partly offset by a reduction in trade receivables from lower year-end commodity prices. CURRENT LIABILITIES increased $120 million from year-end 1996, primarily due to an increase in long-term debt due within one year. NET PROPERTY, PLANT AND EQUIPMENT increased by $268 million from year-end 1996, primarily reflecting property additions in excess of DD&A and dry well write-offs. Net property, plant and equipment for each of the last three years is summarized in the following table: (Dollars in millions) 1997 1996 1995 --------------------------------------------------------------------------- Exploration and production United States $ 3,452 $ 3,172 $ 3,220 International 2,165 2,197 2,419 Refining 751 758 766 Marketing 834 802 753 Transportation 271 285 276 Other 93 84 87 ------- ------- ------- Total $ 7,566 $ 7,298 $ 7,521 --------------------------------------------------------------------------- TOTAL LONG-TERM DEBT AND NOTES PAYABLE at December 31, 1997 was $3.0 billion, essentially unchanged from year-end 1996, mainly reflecting that cash required for Marathon's expanded capital and investment expenditure program and for dividend payments was substantially provided by cash from operating activities, trust withdrawals and asset disposals. Virtually all of the debt is a direct obligation of, or is guaranteed by, USX. Net cash provided from operating activities totaled $1,246 million in 1997, compared with $1,503 million in 1996 and $1,044 million in 1995. Cash provided from operating activities in 1997 included the impact of terminating Marathon's participation in an accounts receivable sales program, resulting in a cash outflow of $340 million. Operating cash flow in 1996 included payments of $39 million related to certain state tax issues, while 1995 included payments of $96 million M-27 Management's Discussion and Analysis CONTINUED representing the Marathon Group's share of the amortized discount on USX's zero coupon debentures. Excluding the effects of these items, net cash from operating activities increased by $44 million in 1997 from 1996 and by $402 million in 1996 from 1995. The increase in 1997 mainly reflected improved net income (excluding the IMV reserve adjustment and other noncash items), partially offset by increased income tax payments. The increase in 1996 was primarily due to favorable working capital changes and improved net income (excluding the IMV reserve adjustment and other noncash items). CAPITAL EXPENDITURES for each of the last three years are summarized in the following table: (Dollars in millions) 1997 1996 1995 ------------------------------------------------------------------------------------------------ Exploration and production ("Upstream") United States $ 647 $ 424 $ 322 International 163 80 141 ------- ------- ------- Total exploration and production 810 504 463 Refining, marketing and transportation ("Downstream") 216 222 169 Other 12 25 10 ------- ------- ------- Total $ 1,038 $ 751 $ 642 ------------------------------------------------------------------------------------------------ During 1997, domestic upstream capital spending mainly included development of Gulf of Mexico properties, including Viosca Knoll 786 (Petronius), Green Canyon 244 (Troika), Ewing Bank 963 (Arnold) and Ewing Bank 917 (Oyster). International upstream spending included development of the West Brae field in the U.K. North Sea and projects in Egypt and offshore Gabon. Downstream spending in 1997 mainly consisted of upgrading and expanding Emro Marketing Company's network of retail outlets, and refinery modification projects. Contract commitments for capital expenditures at year-end 1997 were $268 million, compared with $388 million at year-end 1996. Capital expenditures in 1998 are expected to increase to approximately $1.3 billion, with the increase from 1997 levels mainly due to the inclusion of 100% of the capital requirements for MAP, which commenced operations on January 1, 1998. Domestic upstream projects planned for 1998 include continuing development of Petronius and Green Canyon 112/113 (Stellaria) in the Gulf of Mexico, while international upstream projects include development of the Tchatamba South field, offshore Gabon. Downstream spending by MAP will primarily consist of upgrades and expansions of retail marketing outlets and refinery modifications. INVESTMENTS IN EQUITY AFFILIATES of $233 million in 1997 mainly reflected funding of equity affiliates' capital projects, primarily the Sakhalin II project in the Russian Far East Region and the Nautilus natural gas pipeline system in the Gulf of Mexico. Also included were Marathon's acquisition of an additional 7.5% interest in Sakhalin Energy Investment Company Ltd. ("Sakhalin Energy"), bringing its total interest to 37.5%, investment in the Odyssey crude oil pipeline system in the Gulf of Mexico (with a 29% interest) and acquisition of a 50% ownership in a power generation company in Ecuador. In 1998, investments in equity affiliates are expected to be approximately $150 million, primarily reflecting additional funding of Sakhalin Energy's spending on the Sakhalin II project and funding of power generation projects. Although project expenditures for the Sakhalin II project remain high, third-party financing arranged by Sakhalin Energy is expected to reduce the need for direct investment by Marathon in 1998. The above statements with respect to future capital expenditures and investments are forward-looking statements, reflecting management's best estimates, based on information currently available. To the extent this information proves to be inaccurate, the timing and levels of future spending could differ materially from those included in the forward-looking statements. Factors that could cause future capital expenditures and investments to differ materially from present expectations include industry supply and demand factors, general economic conditions, levels of cash flow from operations, available business opportunities, unforeseen hazards such as weather conditions, and/or by delays in obtaining government or partner approval. In addition, levels of investments may be affected by the ability of equity affiliates to obtain third-party financing. Cash from disposal of assets was $60 million in 1997, compared with $282 million in 1996 and $77 million in 1995. Proceeds in 1997 were mainly from the sales of interests in various domestic upstream properties, certain cost-basis investments and an interest in a domestic pipeline company. Proceeds in 1996 primarily reflected the sales of interests in certain domestic and international oil M-28 Management's Discussion and Analysis CONTINUED and gas production properties and the sale of an equity interest in a domestic pipeline company. Proceeds in 1995 were mainly from the sales of certain domestic oil and gas production properties. WITHDRAWAL FROM PROPERTY EXCHANGE TRUSTS of $98 million in 1997 mainly represented cash withdrawn from an interest-bearing escrow account that was established in 1996 in connection with the disposal of oil production properties in Alaska. FINANCIAL OBLIGATIONS increased $58 million in 1997 as net cash provided from operating activities, trust withdrawals and asset sales was slightly exceeded by cash used for capital expenditures, investments in equity affiliates and dividend payments. Financial obligations consist of the Marathon Group's portion of USX debt and preferred stock of a subsidiary attributed to both groups, as well as debt specifically attributed to the Marathon Group. For discussion of USX financing activities attributed to both groups, see Management's Discussion and Analysis of USX Consolidated Financial Condition, Cash Flows and Liquidity. DIVIDENDS PAID in 1997 increased by $18 million from 1996, mainly due to a two-cents-per-share increase in the quarterly USX - Marathon Group Common Stock dividend rate, initially declared in October 1996. In January 1998, the USX Board of Directors declared a fourth quarter dividend on the USX - Marathon Group Common Stock of 21 cents per share, an increase of two cents per share over the previous quarterly dividend. Total dividends paid on the USX Marathon Group Common Stock in the first quarter of 1998 will increase by approximately $6 million as a result of this increase. DERIVATIVE INSTRUMENTS See Quantitative and Qualitative Disclosures About Market Risk for a discussion of derivative instruments and associated market risk. LIQUIDITY For discussion of USX's liquidity and capital resources, see Management's Discussion and Analysis of USX Consolidated Financial Condition, Cash Flows and Liquidity. MANAGEMENT'S DISCUSSION AND ANALYSIS OF ENVIRONMENTAL MATTERS, LITIGATION AND CONTINGENCIES The Marathon Group has incurred and will continue to incur substantial capital, operating and maintenance, and remediation expenditures as a result of environmental laws and regulations. To the extent these expenditures, as with all costs, are not ultimately reflected in the prices of the Marathon Group's products and services, operating results will be adversely affected. The Marathon Group believes that substantially all of its competitors are subject to similar environmental laws and regulations. However, the specific impact on each competitor may vary depending on a number of factors, including the age and location of its operating facilities, marketing areas, production processes and whether or not it is engaged in the petrochemical or power business or the marine transportation of crude oil and refined products. Marathon Group environmental expenditures for each of the last three years were/(a)/: (Dollars in millions) 1997 1996 1995 ---------------------------------------------------------------------- Capital $ 81 $ 66 $ 50 Compliance Operating & maintenance 84 75 102 Remediation/(b)/ 19 26 37 ------ ------ ------ Total $ 184 $ 167 $ 189 ---------------------------------------------------------------------- /(a)/ Amounts are based on American Petroleum Institute survey guidelines. /(b)/ These amounts do not include noncash provisions recorded for environmental remediation, but include spending charged against such reserves, net of recoveries, where permissible. The Marathon Group's environmental capital expenditures accounted for 8% of total capital expenditures in 1997 and 1995 and 9% in 1996. During 1995 through 1997, compliance expenditures represented 1% of the Marathon Group's total operating costs. Remediation spending during this period was primarily related to retail M-29 Management's Discussion and Analysis CONTINUED marketing outlets which incur ongoing clean-up costs for soil and groundwater contamination associated with underground storage tanks and piping. USX has been notified that it is a potentially responsible party ("PRP") at 20 waste sites related to the Marathon Group under the Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA") as of December 31, 1997. In addition, there are 11 sites related to the Marathon Group where USX has received information requests or other indications that USX may be a PRP under CERCLA but where sufficient information is not presently available to confirm the existence of liability. There are also 71 additional sites, excluding retail marketing outlets, related to the Marathon Group where remediation is being sought under other environmental statutes, both federal and state, or where private parties are seeking remediation through discussions or litigation. At many of these sites, USX is one of a number of parties involved and the total cost of remediation, as well as USX's share thereof, is frequently dependent upon the outcome of investigations and remedial studies. The Marathon Group accrues for environmental remediation activities when the responsibility to remediate is probable and the amount of associated costs is reasonably determinable. As environmental remediation matters proceed toward ultimate resolution or as additional remediation obligations arise, charges in excess of those previously accrued may be required. See Note 27 to the Marathon Group Financial Statements. Effective January 1, 1997, USX adopted the American Institute of Certified Public Accountants Statement of Position No. 96-1 - "Environmental Remediation Liabilities" - which requires that companies include direct costs in accruals for remediation liabilities. Income from operations in 1997 included first quarter charges of $7 million (net of expected recoveries) related to such adoption, primarily for accruals of post-closure monitoring costs, study costs and administrative costs. See Note 3 to the Marathon Group Financial Statements for additional discussion. New or expanded environmental requirements, which could increase the Marathon Group's environmental costs, may arise in the future. USX intends to comply with all legal requirements regarding the environment, but since many of them are not fixed or presently determinable (even under existing legislation) and may be affected by future legislation, it is not possible to predict accurately the ultimate cost of compliance, including remediation costs which may be incurred and penalties which may be imposed. However, based on presently available information, and existing laws and regulations as currently implemented, the Marathon Group does not anticipate that environmental compliance expenditures (including operating and maintenance and remediation) will materially increase in 1998. The Marathon Group's capital expenditures for environmental controls are expected to be approximately $100 million in 1998. Predictions beyond 1998 can only be broad-based estimates which have varied, and will continue to vary, due to the ongoing evolution of specific regulatory requirements, the possible imposition of more stringent requirements and the availability of new technologies, among other matters. Based upon currently identified projects, the Marathon Group anticipates that environmental capital expenditures will be approximately $70 million in 1999; however, actual expenditures may vary as the number and scope of environmental projects are revised as a result of improved technology or changes in regulatory requirements and could increase if additional projects are identified or additional requirements are imposed. USX is the subject of, or party to, a number of pending or threatened legal actions, contingencies and commitments relating to the Marathon Group involving a variety of matters, including laws and regulations relating to the environment, certain of which are discussed in Note 27 to the Marathon Group Financial Statements. The ultimate resolution of these contingencies could, individually or in the aggregate, be material to the Marathon Group financial statements. However, management believes that USX will remain a viable and competitive enterprise even though it is possible that these contingencies could be resolved unfavorably to the Marathon Group. See Management's Discussion and Analysis of USX Consolidated Financial Condition, Cash Flows and Liquidity. M-30 Management's Discussion and Analysis CONTINUED MANAGEMENT'S DISCUSSION AND ANALYSIS OF OPERATIONS The Marathon Group's income from operations and average volumes and selling prices for each of the last three years were as follows: INCOME FROM OPERATIONS/(a)/ (Dollars in millions) 1997 1996 1995 ------------------------------------------------------------------------------------------------- Exploration and production (Upstream) Domestic $ 500 $ 530 $ 306 International 273 374 178 ------- ------- ------ Total exploration and production 773 904 484 Refining, marketing and transportation (Downstream) 563 239 274 Other energy related businesses/(b)/ 48 77 60 Administrative/(c)/ (168) (133) (82) ------- ------- ------ 1,216 1,087 736 Impairment of long-lived assets/(d)/ - - (659) IMV reserve adjustment (284) 209 70 ------- ------- ------ Total $ 932 $ 1,296 $ 147 ------------------------------------------------------------------------------------------------- /(a)/ Consists of operating income, dividend and affiliate income, net gains on disposal of investments and other income.

M-31 Management's Discussion and Analysis CONTINUED DOMESTIC UPSTREAM income from operations decreased by $30 million in 1997 from 1996 following an increase of $224 million in 1996 from 1995. The decrease in 1997 was primarily due to lower liquid hydrocarbon prices and production and higher exploration expense, partially offset by increased natural gas production and prices. In addition, results in 1996 included net losses of $38 million on production hedging activities (see Quantitative and Qualitative Disclosures About Market Risk for the Marathon Group for additional details). The lower liquid hydrocarbon volumes were mostly due to the fourth quarter 1996 disposal of oil producing properties in Alaska, while the increase in natural gas volumes was mainly attributable to properties in east Texas, Oklahoma and Wyoming. The increase in 1996 from 1995 was primarily due to higher average liquid hydrocarbon and natural gas prices, reduced DD&A expense resulting, in part, from the fourth quarter 1995 adoption of SFAS No. 121, and increased natural gas volumes, partially offset by lower liquid hydrocarbon volumes, net losses on hedging activities, higher exploration expense and an unfavorable production tax adjustment for prior years. INTERNATIONAL UPSTREAM income from operations decreased by $101 million in 1997 following an increase of $196 million in 1996. The decrease in 1997 was mainly due to lower liquid hydrocarbon liftings, lower natural gas volumes and lower liquid hydrocarbon prices. These items were partially offset by reduced pipeline and terminal expenses and reduced DD&A expenses, due largely to the lower volumes. The lower liquid hydrocarbon liftings primarily reflected lower production in the U.K. North Sea, while the lower natural gas volumes were mainly due to natural field declines in Ireland and Norway. The increase in 1996 from 1995 primarily reflected higher average liquid hydrocarbon and natural gas prices, reduced DD&A expense resulting, mainly, from property sales and the adoption of SFAS No. 121, lower exploration expense and increased natural gas volumes, partially offset by lower liquid hydrocarbon liftings. Income from operations in 1996 also included a gain on the sale of certain production properties in the U.K. North Sea. DOWNSTREAM income from operations increased by $324 million in 1997 following a decrease of $35 million in 1996. The increase in 1997 was predominantly due to an improvement in refined product margins as favorable effects of reduced crude oil and other feedstock costs more than offset a decrease in refined product sales prices. The decrease in 1996 from 1995 was mainly due to lower refined product margins as increases in wholesale and retail prices were unable to keep up with the increased costs of acquiring crude oil and other feedstocks. In addition, 1996 results included a $10 million charge for the withdrawal from the MPA, a non-profit oil response group, while 1995 results included a $15 million favorable noncash adjustment for expected environmental remediation recoveries. OTHER ENERGY RELATED BUSINESSES income from operations decreased by $29 million in 1997 following an increase of $17 million in 1996. The decrease in 1997 and the increase in 1996 were mainly due to a 1996 gain on the sale of an equity interest in a domestic pipeline company. In the fourth quarter of 1997, the Marathon Group began reporting "Other energy related businesses" as an operating category. This category includes income from operations of Carnegie Natural Gas Company (formerly reported as "Gas Gathering and Processing"), Marathon Power Company, Ltd. and certain activities that were excluded from MAP (such as Marathon's natural gas and crude oil marketing operations and interests in various pipeline companies). ADMINISTRATIVE expenses increased by $35 million in 1997 following an increase of $51 million in 1996 from 1995. The increase in 1997 mainly reflected higher accruals for stock appreciation rights and increased accruals for other employee benefit and compensation plans, including Marathon's performance- based variable pay plan. The increase in 1996 from 1995 primarily resulted from a change in the methodology for distributing costs of certain administrative services to other operating components. M-32 Management's Discussion and Analysis CONTINUED OUTLOOK The outlook regarding the Marathon Group's sales levels, margins and income is largely dependent upon future prices and volumes of crude oil, natural gas and refined products. Prices have historically been volatile and have frequently been driven by unpredictable changes in supply and demand resulting from fluctuations in economic activity and political developments in the world's major oil and gas producing areas, including OPEC member countries. Any substantial decline in such prices could have a material adverse effect on the Marathon Group's results of operations. A prolonged decline in such prices could also adversely affect the quantity of crude oil and natural gas reserves that can be economically produced and the amount of capital available for exploration and development. With respect to Marathon's upstream operations, worldwide liquid hydrocarbon volumes are expected to increase by twenty- five percent in 1998, with most of the increase anticipated in the second half of the year. This primarily reflects projected new production from fields in the Gulf of Mexico (such as Green Canyon 244 and Ewing Bank Blocks 963 and 917), the Tchatamba Marine field in Gabon and the West Brae field in the U.K. North Sea, partially offset by natural production declines of mature fields. Marathon's worldwide natural gas volumes in 1998 are expected to remain consistent with 1997 volumes at around 1.2 billion cubic feet per day, as natural declines in mature international fields, primarily in Ireland and Norway, are anticipated to be offset by increases in domestic production (mainly in the Austin Chalk area in Texas, Green Canyon 244 and the Vermillion Basin in Wyoming). These projections are based on known discoveries and do not include any additions from acquisitions or future exploratory drilling. Other major upstream projects, which are currently underway or under evaluation and are expected to improve future income streams, include Viosca Knoll Block 786 and Green Canyon Blocks 112 and 113 in the Gulf of Mexico, the Tchatamba South field, located offshore Gabon, and the Sakhalin II project in Russia (discussed below). The Marathon Group holds a 37.5% interest in Sakhalin Energy, an incorporated joint venture company responsible for the overall management of the Sakhalin II project. This project includes development of the Piltun-Astokhskoye ("P-A") oil field and the Lunskoye gas field located offshore Sakhalin Island in the Russian Far East Region. During 1997, authorized representatives of the Russian Government approved the Development Plan for the P-A License Area, Phase 1: Astokh Feature. Appraisal work for the remainder of the P-A field was also authorized. The P-A full field development plan is scheduled to be completed and submitted to the Russian Government by June 1999. First production of oil from the Astokh Feature, which will be developed using an arctic-class drilling vessel called the Molikpaq, remains on target for the summer of 1999. Late in 1997, the Sakhalin Energy consortium arranged for a limited recourse project financing facility of $348 million with a group of international financial institutions. Subject to various conditions, initial borrowings by Sakhalin Energy under this facility are anticipated in 1998 to partially fund Phase 1 expenditure requirements. Looking at downstream operations, Marathon and Ashland Inc. officially formed MAP, which commenced operations on January 1, 1998. Major elements of both firms' refining, marketing and transportation operations were combined, with Marathon having a 62% ownership interest in MAP and Ashland holding a 38% interest. MAP has seven refineries with a combined capacity of 935,000 barrels per day ("bpd"), 84 light products and asphalt terminals in the Midwest and Southeast United States, about 5,400 retail marketing outlets in 20 states and significant pipeline holdings. Potential efficiencies derived by MAP have been broadly estimated to be in excess of $200 million annually on a pretax basis. While a modest part of these efficiencies will be achieved in mid- to late 1998, full realization of efficiencies should occur over the next few years as MAP's integration plans are implemented. In conjunction with the formation of MAP, the Marathon Group is expected to recognize an estimated $250 million one-time, pretax change in interest gain in the first quarter of 1998. For additional details of the agreements and the one-time financial gain, see Note 28 to the Marathon Group Financial Statements. MAP's refined product sales volumes for 1998 are expected to increase slightly from 1997 levels of Marathon's and Ashland's separate downstream operations, which were a combined volume of approximately 1.2 million bpd. A major maintenance shutdown ("turnaround") was completed at the Garyville (La.) refinery in early 1998, and major turnarounds are planned for the Canton (Ohio) refinery in the fourth quarter of 1998, the Catlettsburg (Ky.) refinery in the first quarter of 1999 and the Detroit (Mich.) refinery in the fourth quarter of 1999. Each turnaround is expected to last about one month. M-33 Management's Discussion and Analysis CONTINUED The above forward-looking statements of projects, expected production and sales levels, and dates of initial production are based on a number of assumptions, including (among others) prices, supply and demand, regulatory constraints, reserve estimates, production decline rates for mature fields, reserve replacement rates, and geological and operating considerations. In addition, development of new production properties in countries outside the United States may require protracted negotiations with host governments and is frequently subject to political considerations, such as tax regulations, which could adversely affect the economics of projects. With respect to the Sakhalin II project in Russia, Sakhalin Energy continues to seek to have certain Russian laws and normative acts at the Russian Federation and local levels brought into compliance with the existing Production Sharing Agreement Law. To the extent these assumptions prove inaccurate and/or negotiations, legal developments and other considerations are not satisfactorily resolved, actual results could be materially different than present expectations. The above discussion also contains forward-looking statements with respect to the amount and timing of efficiencies to be realized by MAP. Some factors that could potentially cause actual results to differ materially from present expectations include unanticipated costs to implement shared technology, difficulties in integrating corporate structures, delays in leveraging volume procurement advantages or delays in personnel rationalization. YEAR 2000 The Marathon Group continues to identify, analyze, modify and/or replace non-compliant systems, equipment and other devices that utilize date/time-oriented software or computer chips. Marathon has contacted all of its vendors from which systems have been purchased and has requested that appropriate corrections be provided by mid-1998. Modifications to internally developed systems are being handled in-house. In addition, during 1997, Marathon began including Year 2000 provisions in a variety of its contracts. In management's opinion, the incremental costs associated with these efforts will not be material to the operating results of the Marathon Group. This discussion of Marathon's efforts and management's expectations relating to the effect of Year 2000 compliance on operating results are forward-looking statements. Actual results could be materially different because Marathon's ability to achieve Year 2000 compliance and the level of incremental costs associated therewith could be adversely affected by unanticipated problems identified in the ongoing compliance review. In addition, Marathon has limited or no control over comparable corrective actions by proprietary software vendors and other entities with which it interacts. Therefore, Year 2000 compliance problems experienced by these entities could adversely affect the operating results of the Marathon Group. ACCOUNTING STANDARDS In June 1997, the Financial Accounting Standards Board issued two new accounting standards: Statement of Financial Accounting Standards No. 130, "Reporting Comprehensive Income" requires that companies report all recognized changes in assets and liabilities that are not the result of transactions with owners, including those that are not reported in net income. USX plans to adopt the standard, effective with its 1998 financial statements, as required. Statement of Financial Accounting Standards No. 131, "Disclosures about Segments of an Enterprise and Related Information" introduces a "management approach" for identifying reportable industry segments of an enterprise. USX plans to adopt the standard, effective with its 1998 financial statements, as required. M-34 The Marathon Group Quantitative and Qualitative Disclosures About Market Risk MANAGEMENT OPINION CONCERNING DERIVATIVE INSTRUMENTS USX employs a strategic approach of limiting its use of derivative instruments principally to hedging activities, whereby gains and losses are generally offset by price changes in the underlying commodity. Based on this approach, combined with risk assessment procedures and internal controls, management believes that its use of derivative instruments does not expose the Marathon Group to material risk. The Marathon Group's use of derivative instruments for hedging activities could materially affect the Marathon Group's results of operations in particular quarterly or annual periods. This is primarily because use of such instruments may limit the company's ability to benefit from favorable price movements. However, management believes that use of these instruments will not have a material adverse effect on financial position or liquidity. For a summary of accounting policies related to derivative instruments, see Note 2 to the Marathon Group Financial Statements. COMMODITY PRICE RISK AND RELATED RISKS In the normal course of its business, the Marathon Group is exposed to market risk, or price fluctuations related to the purchase, production or sale of crude oil, natural gas and refined products. To a lesser extent, the Marathon Group is exposed to the risk of price fluctuations on natural gas liquids, electricity, and petroleum feedstocks used as raw materials. The Marathon Group is also exposed to effects of price fluctuations on the value of its commodity inventories. The Marathon Group's market risk strategy has generally been to obtain competitive prices for its products and services and allow operating results to reflect market price movements dictated by supply and demand. However, the Marathon Group uses fixed-price contracts and derivative commodity instruments to manage a relatively small portion of its commodity price risk. The Marathon Group uses fixed-price contracts to manage market risk exposure related to the sale of portions of its natural gas production. In addition, the Marathon Group uses derivative commodity instruments such as exchange-traded futures contracts and options, and over- the-counter ("OTC") commodity swaps and options to manage exposure related to the purchase, production or sale of crude oil, natural gas, refined products and electricity. The Marathon Group's strategic approach is to limit the use of these instruments principally to hedging activities. Accordingly, gains and losses on derivative commodity instruments are generally offset by the effects of price changes in the underlying commodity. However, certain derivative commodity instruments have the effect of restoring the equity portion of fixed-price sales of natural gas to variable market-based prices. These instruments are used as part of Marathon's overall risk management programs. M-35 Quantitative and Qualitative Disclosures About Market Risk CONTINUED Sensitivity analyses of the incremental effects on pretax income of hypothetical 10% and 25% changes in commodity prices for open derivative commodity instruments for the Marathon Group as of December 31, 1997, are provided in the following table:/(a)/ (Dollars in millions) -------------------------------------------------------------------------------- INCREMENTAL DECREASE IN PRETAX INCOME ASSUMING A HYPOTHETICAL PRICE CHANGE OF/(a)/ Derivative Commodity Instruments 10% 25% -------------------------------------------------------------------------------- Crude oil (price increase)/(b)/ $2.7 $ 8.6 Natural gas (price decrease)/(b)/ 2.9 7.1 Refined products (price decrease)/(b)/ .4 1.1 ---- ----- Total $6.0 $16.8 -------------------------------------------------------------------------------- /(a)/ Gains and losses on derivative commodity instruments are generally offset by price changes in the underlying commodity. Effects of these offsets are not reflected in the sensitivity analyses. Amounts reflect the estimated incremental effect on pretax income of hypothetical 10% and 25% changes in closing commodity prices for each open contract position at December 31, 1997. The Marathon Group evaluates its portfolio of derivative commodity instruments on an ongoing basis and adds or revises strategies to reflect anticipated market conditions and changes in risk profiles. Changes to the size or composition of the portfolio subsequent to December 31, 1997, would cause future pretax income effects to differ from those presented in the table. The number of net open contracts varied throughout 1997, from a low of 637 contracts at December 31, to a high of 9,307 contracts at June 11, and averaged 5,400 for the year. The derivative commodity instruments used and hedging positions taken also varied throughout 1997, and will continue to vary in the future. Because of these variations in the composition of the portfolio over time, the number of open contracts, by itself, cannot be used to predict future income effects. During 1998, the size of the portfolio is expected to increase above average 1997 levels as a result of increased volumes for Marathon Ashland Petroleum LLC, on a basis consistent with guidelines established in previously existing downstream hedging programs. The calculation of sensitivity amounts for basis swaps assumes that the physical and paper indices are perfectly correlated. Gains and losses on options are based on the difference between the strike price and the underlying commodity price. /(b)/ The direction of the price change used in calculating the sensitivity amount for each commodity reflects that which would result in the largest incremental decrease in pretax income when applied to the derivative commodity instruments used to hedge that commodity. While derivative commodity instruments are generally used to reduce risks from unfavorable commodity price movements, they also may limit the opportunity to benefit from favorable movements. During the fourth quarter of 1996, certain hedging strategies matured which limited the Marathon Group's ability to benefit from favorable market price increases on the sales of equity crude oil and natural gas production, resulting in pretax hedging losses of $33 million. In total, Marathon's upstream operations recorded pretax hedging losses of $3 million in 1997, compared with net losses of $38 million in 1996, and net gains of $10 million in 1995. Marathon's downstream operations generally use derivative commodity instruments to lock-in costs of certain raw material purchases, to protect carrying values of inventories and to protect margins on fixed-price sales of refined products. In total, downstream operations recorded net pretax hedging gains of $29 million in 1997, compared with net losses of $22 million in 1996 and $4 million in 1995. Essentially, all of these upstream and downstream gains and losses were offset by changes in the prices of the underlying hedged commodities, with the net effect approximating the targeted results of the hedging strategies. For additional information relating to derivative commodity instruments, including aggregate contract values, and fair values, where appropriate, see Note 25 to the Marathon Group Financial Statements. The Marathon Group is subject to basis risk, caused by factors that affect the relationship between commodity futures prices reflected in derivative commodity instruments and the cash market price of the underlying commodity. Natural gas transaction prices are frequently based on industry reference prices that may vary from prices experienced in local markets. For example, New York Mercantile Exchange ("NYMEX") contracts for natural gas are priced at Louisiana's Henry Hub, while the underlying quantities of natural gas may be produced and sold in the Western United States at prices that do not move in strict correlation with NYMEX prices. To the extent that commodity price changes M-36 Quantitative and Qualitative Disclosures About Market Risk CONTINUED in one region are not reflected in other regions, derivative commodity instruments may no longer provide the expected hedge, resulting in increased exposure to basis risk. These regional price differences could yield favorable or unfavorable results. OTC transactions are being used to manage exposure to most of the basis risk. The Marathon Group is subject to liquidity risk, caused by timing delays in liquidating contract positions due to a potential inability to identify a counterparty willing to accept an offsetting position. Due to the large number of active participants, exposure to liquidity risk is relatively low for exchange-traded transactions. INTEREST RATE RISK USX is subject to the effects of interest rate fluctuations on certain of its non-derivative financial instruments. A sensitivity analysis of the projected incremental effect of a hypothetical 10% decrease in year-end 1997 interest rates on the fair value of the Marathon Group's specifically attributed non-derivative financial instruments and the Marathon Group's portion of USX's non- derivative financial instruments attributed to all groups, is provided in the following table: (Dollars in millions) --------------------------------------------------------------------------------------------------------- Incremental Increase in Carrying Fair Fair Non-Derivative Financial Instruments/(a)/ Value /(b)/ Value /(b)/ Value /(c)/ --------------------------------------------------------------------------------------------------------- Financial assets: Investments and long-term receivables/(d)/ $ 86 $ 143 $ -- --------------------------------------------------------------------------------------------------------- Financial liabilities: Long-term debt (including amounts due within one year)/(e)/ $2,869 $3,198 $ 106 Preferred stock of subsidiary/(f)/ 184 187 18 ----- ----- ------- Total $3,053 $3,385 $ 124 --------------------------------------------------------------------------------------------------------- /(a)/ Fair values of cash and cash equivalents, receivables, notes payable, accounts payable and accrued interest, approximate carrying value and are relatively insensitive to changes in interest rates due to the short-term maturity of the instruments. Accordingly, these instruments are excluded from the table. /(b)/ At December 31, 1997. For further discussion, see Note 26 to the Marathon Group Financial Statements. /(c)/ Reflects, by class of financial instrument, the estimated incremental effect of a hypothetical 10% decrease in interest rates at December 31, 1997, on the fair value of non- derivative financial instruments. For financial liabilities this assumes a 10% decrease in the weighted average yield to maturity of USX's long-term debt at December 31, 1997. /(d)/ For additional information, see Note 19 to the Marathon Group Financial Statements. /(e)/ Fair value was based on market prices where available, or current borrowing rates for financings with similar terms and maturities. For additional information, see Note 11 to the Marathon Group Financial Statements. /(f)/ In 1994, USX Capital LLC, a wholly owned subsidiary of USX, sold 10,000,000 shares of 8-3/4% Cumulative Monthly Income Preferred Shares. For further discussion, see Note 25 to the Consolidated Financial Statements. At December 31, 1997, USX's portfolio of long-term debt was comprised primarily of fixed-rate instruments. Therefore, the fair value of the portfolio is relatively sensitive to effects of interest rate fluctuations. This sensitivity is illustrated by the $106 million increase in the fair value of long-term debt assuming a hypothetical 10% decrease in interest rates. However, USX's sensitivity to interest rate declines and corresponding increases in the fair value of its debt portfolio would unfavorably affect USX's results and cash flows only to the extent that USX elected to repurchase or otherwise retire all or a portion of its fixed-rate debt portfolio at prices above carrying value. FOREIGN CURRENCY EXCHANGE RATE RISK The Marathon Group is subject to the risk of price fluctuations related to anticipated revenues and operating costs, firm commitments for capital expenditures and existing assets or liabilities denominated in currencies other than U.S. dollars. USX has not generally used derivative instruments to manage this risk. However, USX has made limited use of forward currency contracts to manage exposure to certain currency price fluctuations. At December 31, 1997, a forward currency contract with a fair value of $10 million was outstanding. The Marathon Group's attributed portion of the contract was $9 million. This contract hedges exposure to currency price fluctuations relating to a Swiss franc debt obligation with a fair value of $69 million at December 31, 1997. The debt obligation and forward contract mature in 1998. M-37 Quantitative and Qualitative Disclosures About Market Risk CONTINUED EQUITY PRICE RISK The Marathon Group holds investments in common stock and warrants of certain third parties. The fair value of these investments ($17 million at December 31, 1997) has not been material. SAFE HARBOR The Marathon Group's quantitative and qualitative disclosures about market risk include forward-looking statements as defined in the Private Securities Litigation Reform Act of 1995. These statements are accompanied by cautionary language identifying important factors (particularly the underlying assumptions and limitations disclosed in footnotes to the tables), though not necessarily all such factors, that could cause future outcomes to differ materially from those projected. Forward-looking statements with respect to management's opinion about risks associated with USX's use of derivative instruments, and projected increases in the size of the Marathon Group's hedge portfolio are based on certain assumptions with respect to market prices and industry supply of and demand for crude oil, refined products and certain raw materials. To the extent that these assumptions prove to be inaccurate, future outcomes with respect to the Marathon Group's hedging programs may differ materially from those discussed in the forward-looking statements.
