A30 SOUTHERN PERU COPPER CORPORATION and SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 1. Summary of Significant Accounting Policies Principles of consolidation: The consolidated financial statements of Southern Peru Copper Corporation and Subsidiaries (the Company) include the accounts of significant subsidiaries in which the Company has voting control, and are prepared in accordance with generally accepted accounting principles in the United States (U.S. GAAP). Certain prior year amounts have been reclassified to conform to the current year's presentation. Use of estimates: The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Revenue recognition: Substantially all of the Company's copper is sold under annual contracts. Sales are recognized when title passes. Pricing is based on prevailing monthly average London Metal Exchange (LME) copper prices for a quotation period, generally being the month of, the month prior or the month following the actual or contractual month of shipment or delivery according to the terms of the contracts. Price estimates used for provisionally priced sales are based on prices in effect at the time of shipment or period end prices, if lower, and these estimates are subject to change during the settlement period. The Company sells copper in blister and refined form at industry standard commercial terms. Net sales include the invoiced value of copper, silver, molybdenum, and gains from the sale or settlement of copper put options. Cash equivalents and marketable securities: Cash equivalents include all highly liquid investments with a maturity of three months or less, when purchased. Marketable securities include short-term liquid investments with a maturity of more than three months, when purchased, and are carried at cost, which approximates market. Inventories: Metal inventories are carried at the lower of average cost or market. Costs incurred in the production of metal inventories exclude general and administrative costs. Supplies inventories are carried at average cost less a reserve for obsolescence. Property: Assets are valued at cost or net realizable value. In accordance with SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of", the Company reviews long-lived assets, certain identifiable intangibles and goodwill related to those assets for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. The impairment loss on such assets, as well as long-lived assets and certain identifiable intangibles to be disposed of, is measured as the amount by which the carrying value of the assets exceeds the fair value of the assets (less disposal costs, if applicable). The Company evaluates the carrying value of assets based on undiscounted future cash flows considering expected metal prices based on historical metal prices and price trends. A31 Betterments, renewals, costs of bringing new mineral properties into production, and the cost of major development programs at existing mines are capitalized as mineral land. Maintenance, repairs, normal development costs at existing mines, and gains or losses on assets retired or sold are reflected in earnings as incurred. Buildings and equipment are depreciated on the straight-line method over estimated lives from 5 to 40 years, or the estimated life of the mine if shorter. Depletion of mineral land is computed by the units-of-production method using proven and probable ore reserves. Exploration: Tangible and intangible costs incurred in the search for mineral properties are charged against earnings when incurred. Financial Instruments: The Company may use derivative instruments to manage its exposure to market risk from changes in commodity prices. Derivative instruments which are designated as hedges must be deemed effective at reducing the risk associated with the exposure being hedged and must be designated as a hedge at the inception of the contract. Depending on the market fundamentals of a metal and other conditions, the Company may purchase put options to reduce or eliminate the risk of metal price declines below the option strike price on a portion of its anticipated future production. The cost of options is amortized on a straight-line basis during the period in which the options are exercisable. Gains or losses from the sale or exercise of options, net of unamortized acquisition costs, are recognized in the period in which the underlying hedged production is sold and are reported as a component of the underlying transaction. The Company may enter into fuel swap agreements to limit the effect of fuel price changes on production costs. A fuel swap establishes a fixed price for the quantity of fuel covered by the agreement. The difference between the published price for fuel and the price established in the contract for the month covered by the swap is recognized in production costs. Stock Based Compensation: In 1996 the Company elected to apply the disclosure only provisions of Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based Compensation." Impact of New Accounting Standard: In 1997 the Company adopted Statement of Financial Accounting Standards No. 128, "Earnings per Share." The statement did not have a material impact on the Company's financial statements. In June 1997, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 130, "Reporting Comprehensive Income." This statement which is effective for fiscal years beginning after December 15, 1997, requires the Company to make certain disclosures but has no impact on the Company's financial statements. 2. Exchange Offer Southern Peru Copper Holding Company, (the Holding Company), was incorporated on September 7, 1995, pursuant to the General Corporation Law of the State of Delaware for the purpose of conducting an exchange offer of its common stock, par value $0.01 per share for any and all labor shares of the Peruvian Branch (the Branch) of Southern Peru Copper Corporation (the Operating Company). In connection with the exchange offer, the Operating Company changed its name to Southern Peru Limited (SP Limited) and the Holding Company changed its name to Southern Peru Copper Corporation. A32 The exchange offer expired on December 29, 1995, with 80.8% of the labor shares tendered which reduced the interest of labor shares from 17.3% to 3.3%. The common stock is listed on the New York Stock Exchange and the Lima Stock Exchange and trading commenced January 5, 1996. In addition, the stockholders of SP Limited exchanged 65,717,493 shares of their common stock for 68,750,833 shares of Class A common stock in the Company. With the completion of the exchange offer, the Company has outstanding two classes of common stock, the common stock exchanged for labor shares and Class A common stock which at December 31, 1997, represented 17.8% and 82.2% of the common equity of the Company, respectively. Holders of common stock are entitled to one vote per share and holders of Class A common stock are entitled to five votes per share except for the election of directors and as required by law. The exchange of common stock for labor shares was accounted for as a purchase of a minority interest. The value of the common stock issued in the exchange (based on the average per share trading value for the three business days ended January 9, 1996) plus issuance costs exceeded the carrying value of the minority interests acquired by $82.0 million, net of income taxes. The increase in value was assigned to proven and probable sulfide and leachable ore reserves and mineralized material which is being amortized based on the units of production method, and to metal inventory. The following table provides the comparative unaudited proforma 1995 earnings information, as if the exchange offer were completed on January 1, 1995: 1995 (Unaudited) Historical Proforma (in millions, except per share data) Net sales $ 928.8 $ 928.8 ------ ------ Earnings before taxes on income and minority interest of labor shares 380.4 370.7(a) Taxes on income 119.1 118.9(b) Minority interest of labor shares in Peruvian Branch 43.5 7.7(c) -- ---- ---- Net earnings $ 217.8 $ 244.1 ====== ====== Net earnings per share (basic and diluted) $ 3.31 $ 3.04 Cash dividends paid per share $ 1.27 $ 1.04 Weighted average number of shares outstanding 65.7 80.2 (a) The market value of the common stock issued for labor shares tendered pursuant to the exchange offer was in excess of the book value of the minority interest of such labor shares. This excess was assigned to proven and probable mineral reserves, mineralized material and to metal inventory. Proforma earnings reflect the amortization of the excess of market value over book value which was assigned to mineral reserves and mineralized material, based on actual copper production and a charge to cost of products sold of the excess amount which would have been assigned to metal inventory at January 1, 1995. (b) Reflects the reduction of the deferred income taxes related to the amortization of the excess of the market value of common stock issued for labor shares tendered pursuant to the exchange offer over the book value of the minority interest of such labor shares. (c) Reflects the reduction of the minority interest of the labor shares tendered pursuant to the exchange offer. A33 3. Foreign Exchange The functional currency of the Company is the U.S. dollar. The Company's sales, cash, trade receivables, fixed asset additions, trade payables and debt are primarily dollar-denominated. A portion of the operating costs of the Company is denominated in Peruvian soles. Gains resulting from foreign currency transactions are included in "Other income" and amounted to $2.0 million, $6.7 million and $6.0 million in 1997, 1996 and 1995, respectively. 4. Taxes on Income The components of the provision for taxes on income are as follows: For the years ended December 31, 1997 1996 1995 ---- ---- ---- (in millions) ------------------- --------------- --------------- U.S. Federal and state $ 10.6 $ 5.3 $ 4.6 ------------------- --------------- --------------- Foreign: Current 52.3 62.9 111.3 Deferred (7.3) 12.0 3.2 ------------------- --------------- --------------- Foreign 45.0 74.9 114.5 =================== =============== =============== Total provision for income taxes $ 55.6 $ 80.2 $ 119.1 =================== =============== =============== Total taxes paid were $30.1 million, $123.4 million and $80.1 million in 1997, 1996 and 1995, respectively. Reconciliation of the statutory income tax rate to the effective income tax rate is as follows: For the years ended December 31, 1997 1996 1995 ---- ---- ---- Peruvian income tax at maximum statutory rates 30.0% 30.0% 30.0% U.S. income tax at statutory rate 35.0 35.0 35.0 Utilization of foreign tax credits (16.9) (25.3) (27.9) Peruvian reinvestment allowance (9.0) - - Alternative minimum tax (AMT) credit (3.4) - - Percentage depletion (9.6) (9.0) (6.6) Income not deductible (not taxable) in Peru (2.6) (1.8) 0.1 Other (0.9) 1.3 0.7 ==================== =================== ==================== Effective income tax rate 22.6% 30.2% 31.3% ==================== =================== ==================== A34 Temporary differences and carryforwards which give rise to deferred tax assets, liabilities and related valuation allowances are as follows: Deferred tax assets (liabilities) At December 31, 1997 1996 ---- ---- (in millions) Current: Accounts receivable $1.6 $ 0.5 Inventories 0.1 0.1 ------------------- ------------------ Net deferred tax assets 1.7 0.6 ------------------- ------------------ Non-current: Foreign tax credit carryforwards - 69.4 AMT credit carryforwards - 6.8 Property, plant and equipment (43.5) (48.7) Other (0.8) (0.7) Valuation allowance for deferred tax assets - (76.2) ------------------- ------------------ Net deferred tax liabilities (44.3) (49.4) ------------------- ------------------ Total net deferred tax liabilities $(42.6) $ (48.8) =================== ================== The decrease in the valuation allowance of $76.2 million from 1996 to 1997 is primarily attributable to the utilization of foreign tax credits and alternative minimum tax credits in 1997. In the first quarter of 1997, the Government of Peru approved a reinvestment allowance for the Company's program to expand the Cuajone Mine. The reinvestment allowance provides SPCC with tax incentives in Peru, and as a result, certain U.S. tax credit carryforwards, for which no benefit had previously been recorded, were realized. The reduction in the effective tax rate, as a result of the reinvestment allowance for the twelve months ended December 31, 1997, lowered tax expense approximately $14.7 million. Pursuant to the reinvestment allowance SPCC has received tax deductions in Peru in amounts equal to the cost of the qualifying property (approximately $245 million). As qualifying property is acquired, the financial statement carrying value of the qualifying property will be reduced to reflect the tax benefit associated with the reinvestment allowance (approximately $73 million). As a result, financial statement depreciation expense related to the qualifying property will be reduced over its useful life (approximately 15 years). The Company obtains income tax credits in Peru for value-added taxes (VAT)paid in connection with the purchase of capital equipment and other goods and services employed in its operations and records these credits as a prepaid expense. Under current Peruvian law, the Company is entitled to use the credits against its Peruvian income tax liability or to receive a refund. The carrying value of these Peruvian tax credits approximates their market value. A35 5. Net Sales Net sales by country were as follows: For the years ended December 31, 1997 1996 1995 ---- ---- ---- (in millions) United States $132.1 $ 77.4 $ 60.3 Italy 110.0 109.4 153.0 United Kingdom 98.4 110.3 108.8 The Netherlands 83.8 94.3 189.7 Japan 72.5 82.0 102.4 Foreign - Other 317.4 279.6 314.6 ================ ============== =============== Net sales $814.2 $753.0 $928.8 ================ ============== =============== At December 31, 1997, the Company had recorded sales of 42.1 million pounds of copper at a provisional price of 78.2 cents per pound. These sales are subject to final pricing based on the average monthly LME copper price in the month of final settlement which will occur principally in the first quarter of 1998. Under the terms of a sales contract with Union Miniere, the Company is required to supply Union Miniere, through its agent, S.A. Sogem N.V., with 46,300 tons of blister copper annually for a ten year period from January 1, 1994, through December 31, 2003. The price of the copper, contained in blister, supplied under the contract is determined based on the LME monthly average settlement price less a refining allowance, which is agreed upon annually based on world market terms. Under the terms of a sales contract with Mitsui & Co. Ltd (Mitsui), the Company is required to supply to Mitsui, at its option, up to 26,455 tons of copper cathodes annually for a seven year period from January 1, 1994 through December 31, 2000. Pricing of the cathodes is based upon the LME monthly average settlement price plus a producer premium which is agreed upon annually based on world market terms. 6. Financial Instruments Hedging Activities: The Company may use derivative instruments to manage its exposure to market risk from changes in commodity prices. Derivative instruments which are designated as hedges must be deemed effective at reducing the risk associated with the exposure being hedged and must be designated as a hedge at the inception of the contract. Copper: Depending on the market fundamentals and other conditions, the Company may purchase put options to reduce or eliminate the risk of price declines below the option strike price on a portion of its anticipated future production. Put options purchased by the Company establish a minimum sales price for the production covered by such put options and permit the Company to participate in price increases above the option price. The cost of options is amortized on a straight-line basis during the period in which the options are exercisable. Depending upon market conditions the Company may either sell options it holds or exercise the options at maturity. Gains or losses from the sale or exercise of options, net of unamortized acquisition costs, are recognized in the period in which the underlying production is sold and are reported as a component of the underlying transaction. A36 Earnings include gains from option sales and exercises of $10.2 million in 1997, $9.9 million in 1996 and losses of $2.1 million in 1995. At December 31, 1997, the Company held the following copper put options: (in millions, except per pound amounts) Percent of Strike Price Unamortized Estimated Pounds Period Per Pound Cost Production - ------------ ------------------- ---------------------- --------------------- ------------------------------- 44.0 1/98-3/98 $0.95 $0.6 27% Fuel Swaps: The Company may enter into fuel swap agreements to limit the effect of changes in fuel prices on its production costs. A fuel swap establishes a fixed price for the quantity of fuel covered by the agreement. The difference between the published price for fuel and the price established in the contract for the month covered by the swap is recognized in production costs. As of December 31, 1997, the Company has entered into the following fuel swap agreements: Percent of Quantity Contract Estimated Fuel Fuel Type Period (Barrels) Price Requirement - --------------------------- ----------------------- ------------------------ ------------------------ ------------------------ Residual Oil #6: 1/98-3/98 270,000 $13.21 88% 4/98-12/98 270,000 $13.93 30% Diesel Fuel #2: 1/98-3/98 80,500 $20.83 54% 4/98-12/98 120,000 $21.40 27% The estimated fair value of the Company's financial instruments is: At December 31, 1997 1996 (in millions) Carrying Fair Carrying Fair Value Value Value Value Assets: Cash and cash equivalents $126.5 $126.5 $ 173.2 $ 173.2 Marketable securities - held to maturity 204.6 204.6 1.0 1.0 Put options 0.6 7.2 - - Fuel swap agreements - (0.5) - - Liabilities: Long-term debt $247.9 $248.3 $ 106.6 $ 102.3 The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value: Cash and cash equivalents - The carrying amount approximates fair value because of the short maturity of these instruments. Marketable securities - The carrying amount and fair value are reported at amortized cost, which approximates market, since these securities are to be held to maturity. A37 Put options - Fair value is an estimate based on relevant market information such as: volatility of similar options, futures prices and the contracted strike price. Fuel swap agreements - Fair value is based on quoted market prices. Long-term debt - Fair value is based on the quoted market prices for the same or similar issues. 7. Workers' Participation Provisions for workers' participation are calculated at 8% of pre-tax Branch earnings as required by Peruvian law. This participation is accrued during the year and distributed to workers following determination of final results for the year. 8. Minority Interest of Labor Shares The minority interest of the labor shares is based on the earnings of the Company's Peruvian Branch. During 1997 and 1996, the Company acquired approximately 2.0 million (1.8 million in 1996) labor shares representing a 0.6% (0.5% in 1996) interest in the Branch at a total cost of $8.9 million ($7.1 million in 1996). The carrying value of the minority interest was reduced by $5.1 million and the excess paid over the carrying value of $3.8 million was assigned primarily to proven and probable sulfide and leachable ore reserves and mineralized material and is being amortized based on production. As a result of the acquisition, the remaining labor shareholders hold a 2.2% interest in the Branch at December 31, 1997, and are entitled to a pro rata participation in the cash distributions made by the Branch. The labor shares are recorded as a minority interest in the Company's financial statements. 9.

Fees paid for loan agreements of $13.9 million and $1.6 million in 1997 and 1995, respectively, are included in other assets and amortized over the respective terms of the loans. Aggregate maturities of the borrowings outstanding at December 31, 1997, are as follows (in millions): 1998 $13.7 1999 13.7 2000 23.3 2001 24.3 2002 18.9 Thereafter 154.0 -------------------- Total $247.9 -------------------- In April 1997, the Company entered into a $600 million seven-year credit agreement with a group of international financial institutions. The agreement consists of a $400 million term loan facility and a $200 million revolving credit facility. The interest rate during the first three years of the agreement on any loans outstanding is LIBOR plus 1.75% per annum for term loans and LIBOR plus 2.0% for revolving credit loans. A commitment fee of 0.5% per annum is payable on the undrawn portion of the facility. No amounts have been drawn under this agreement as of December 31, 1997. A39 In May 1997, the Company privately placed $150 million of Secured Export Notes in the United States and international markets. These notes were issued with an average maturity of seven years and a final maturity in 2007 and were priced at par with a coupon rate of 7.9%. In addition, in June 1997 the Company sold $50 million of 8.25% bonds due June 2004 to investors in Peru. Some financing agreements contain covenants which limit the payment of dividends to stockholders. Under the most restrictive covenant, the Company may pay dividends to stockholders equal to 50% of its net income for any fiscal quarter as long as such dividends are paid by June 30 of the following year. As a result, net assets of the Company unavailable for the payment of dividends totaled $1,082 million at December 31, 1997. In accordance with the most restrictive covenant of the Company's loan agreements, additional indebtedness of $849.7 million would have been permitted at December 31, 1997. The EXIM Bank credit agreement is collateralized by pledges of receivables from sales of 7,700 tons of copper per year. The CAF loan is collateralized by liens on the SX/EW facility. The Secured Export Notes and the seven-year loan facility require that most of the collections of export copper sales be deposited into a trust account in the United States. Twenty percent of these collections are used as collateral for the outstanding Secured Export Notes with the balance of the collections remitted directly to the Company. The excess funds in the collateral account are remitted to the Company, if all financial requirements are met. As part of these agreements, the Company must maintain three month and six month collection ratios, as defined (aggregate collection as a specified multiple of debt service). Both facilities require escrow deposits of three months debt service. In addition, certain of the agreements require the Company to maintain a minimum stockholders' equity of $750 million, specified ratios of debt to equity, current assets to current liabilities and an interest coverage test. Reduction of ASARCO Incorporated's (Asarco) voting interest in the Company to less than a majority would constitute an event of default under one of the financing agreements. The Company is in compliance with the various loan covenants at December 31, 1997. Included in Other Assets are $13.5 million held in escrow accounts as required by the Company's loan agreements. The funds will be released from escrow as scheduled loan repayments are made. 13. Benefit Plans The Company has two noncontributory, defined benefit pension plans covering salaried employees in the United States and certain employees in Peru. Benefits are based on salary and years of service. The Company's funding policy is to contribute amounts to the plans sufficient to meet the minimum funding requirements set forth in the Employee Retirement Income Security Act of 1974, plus such additional amounts as the Company may determine to be appropriate. Plan assets are primarily invested in immediate participation guarantee contracts, mutual funds, stock index funds and deposit administration contracts. Effective January 1, 1997 one of the Company's pension plans, which provides benefits to non-U.S. expatriate employees, was amended to cease future benefit accruals. Accordingly, those participants became eligible for future benefits under the Company's other pension plan. A40 Net pension costs consisted of: For the years ended December 31, 1997 1996 1995 (in millions) ---- ---- ---- Service cost $ 0.4 $ 0.5 $ 0.3 Interest cost on projected benefit obligations 0.6 0.5 0.4 Actual return on plan assets (0.6) (0.6) (0.4) Other items - 0.4 0.3 ------------------- ------------------- -------------------- Net pension cost $ 0.4 $ 0.8 $ 0.6 ------------------- ------------------- -------------------- The funded status of the plans using the projected unit credit method is: At December 31, 1997 1996 (in millions) ---- ---- Assets and obligations: Vested benefit obligation $7.8 $ 5.3 Nonvested benefits 0.5 0.5 ------------------- ----------------- Accumulated benefit obligation 8.3 5.8 Plan assets at fair value 9.0 5.0 ------------------- ----------------- ------------------- ----------------- Plan assets in excess of (less than) accumulated benefit obligation 0.7 (0.8) ------------------- ----------------- ------------------- ----------------- Projected benefit obligation (PBO) 9.7 7.2 Plan assets at fair value 9.0 5.0 ------------------- ----------------- Plan assets less than PBO (0.7) (2.2) Minimum liability - (0.5) Prior service cost (0.1) (0.1) Initial net plan obligation 1.8 2.1 Effect of changes in assumptions and actuarial gains and losses (0.6) (0.2) ------------------- ----------------- Pension asset (liability) reflected in consolidated balance sheet $0.4 $(0.9) =================== ================= The actuarial computations for 1997 and 1996 are based upon a discount rate on benefit obligations of 7%, an expected long-term rate of return on plan assets of 8% and expected annual salary increases of 4%. Post-retirement Benefits: The post-retirement health care plan for retired salaried employees eligible for Medicare was adopted by the Company on May 1, 1996. Secondary coverage under the Company's plan is available for all retired salaried employees who permanently reside in the United States and who contribute amounts as defined by the plan. Net periodic post-retirement benefit costs include: For the year ended December 31, 1997 1996 (in millions) ---- ---- Service and interest cost $0.1 $0.1 Amortization of prior service cost 0.1 0.1 --- --- Net periodic post-retirement benefit costs $0.2 $0.2 ==== ==== A41 The following sets forth the plan's status reconciled with amounts reported in the Consolidated Balance Sheet: At December 31, 1997 1996 (in millions) ---- ---- Accumulated post-retirement benefit obligation (APBO): Retirees $0.2 $0.2 Fully eligible active plan participants 0.1 0.1 Other plan participants 0.6 0.6 --- --- Total APBO 0.9 0.9 Item not yet recognized in earnings: Prior service cost (0.5) (0.7) ----- ----- Post-retirement benefit obligation $0.4 $0.2 ==== ==== The annual assumed rate of increase in the per capita cost of covered benefits (i.e. health cost trend rate) is 6% for 1997 and 1996 and is assumed to decrease gradually to 5% by 1999 and remain at that level thereafter. The health care cost trend rate assumption has a significant effect on the amounts reported. For example, increasing the assumed health care cost trend rates by one percentage point in each year would increase the accumulated post-retirement benefit obligation at December 31, 1997 by $0.1 million and would have no material effect on the net periodic post-retirement benefit costs for 1997. The discount rate used in determining the accumulated post-retirement benefit obligation was 7% at December 31, 1997 and 1996. The plan is unfunded. Employee Savings Plan: The Company maintains an employee savings plan for employees working in the United States and expatriate employees in Peru which permits employees to make contributions by salary reduction pursuant to section 401(k) of the Internal Revenue Code. The plan was amended, effective January 1, 1997, to include a Company matching contribution equal to 50% of the first 6% of employee contributions. In connection with the required match, the Company's contributions charged against earnings were $0.2 million in 1997. 14. Stockholders' Equity Common Stock: The stockholders of the Company at December 31, 1997 were: Percent of Total Number of -------------------- -------------------- Class A Common Shares: ASARCO Incorporated 43,348,949 54.1% Cerro Trading Company, Inc. 11,378,088 14.2% Phelps Dodge Overseas Capital Corporation 11,173,796 14.0% -------------------- -------------------- -------------------- -------------------- Total Class A Common Shares 65,900,833 82.3% Common Shares 14,157,107 17.7% -------------------- -------------------- Total 80,057,940 100.0% -------------------- -------------------- -------------------- -------------------- A42 On March 3, 1997, Cerro Trading Company, Inc. transferred 650,000 Class A common shares to The Pritzker Family Philanthropic Fund. In accordance with the Company's Certificate of Incorporation these shares were automatically converted into common stock of the Company. Stock Options: The Company has two stockholder approved plans, a Stock Incentive Plan and a Directors' Stock Award Plan. The Stock Incentive Plan provides for the granting of nonqualified or incentive stock options, as defined under the Internal Revenue Code of 1986, as amended, as well as for the award of restricted stock and bonuses payable in stock. The price at which options may be granted under the Stock Incentive Plan shall not be less than 100% of the fair market value of the common stock on the date of grant in the case of incentive stock options, or 50% in the case of other options. In general, options are not exercisable for six months and expire after 10 years from the date of grant. Options granted may provide for Stock Appreciation Rights (SAR). An SAR permits an optionee, in lieu of exercising the option, to receive from the Company payment of an amount equal to the difference between the market value of the stock on the date of election of the SAR and the purchase price of the stock under the terms of the option. The authorized number of shares under the Stock Incentive Plan is 1,000,000 of which 300,000 may be awarded as restricted stock. At December 31, 1997, 836,635 shares are available for future grants under this plan (927,110 shares at December 31, 1996). The Directors' Stock Award Plan provides that directors who are not compensated as employees of the Company will be automatically awarded 200 shares of common stock upon election and 200 additional shares following each annual meeting of stockholders thereafter. Under the directors plan, 100,000 shares have been reserved for awards. At December 31, 1997, 8,400 shares have been awarded under this plan. The Company has adopted the disclosure-only provisions of SFAS No. 123, "Accounting for Stock-Based Compensation". Accordingly, no compensation cost has been recognized for awards under the stock option plan. If compensation cost for the Company's Stock Incentive Plan had been determined based on the fair value at the grant date for awards in 1997 and 1996, consistent with the provisions of SFAS No. 123, the Company's net earnings and earnings per share would have been reduced to the proforma amounts indicated below: (in millions, except per share amounts) 1997 1996 ---- ---- Net earnings - as reported $185.7 $180.5 Net earnings - pro forma $185.5 $180.4 Earnings per share (Basic) - as reported $ 2.32 $ 2.25 Earnings per share (Diluted) - as reported $ 2.32 $ 2.25 Earnings per share (Basic) - pro forma $ 2.32 $ 2.25 Earnings per share (Diluted) - pro forma $ 2.32 $ 2.25 A43 For purposes of computing earnings per share, basic and diluted, the dilutive effect of stock options on common shares outstanding is as follows: Weighted average common shares outstanding: 1997 1996 (in millions) ---- ---- Basic 80.2 80.2 Dilutive effect of stock options - - ================= ============== Diluted 80.2 80.2 ================= ============== The fair value of each option grant was estimated on the date of grant using the Black-Scholes option-pricing model with the following assumptions used for grants in 1997: dividend yield of 4.05% (6.57%-1996); expected volatility of 29.2% (28.4%-1996); risk-free interest rate of 6.31% (6.17%-1996); and expected life of 7.0 years (6.9 years-1996). Stock option activity over the past two years under the Stock Incentive Plan was: Weighted Number of Average Option Price Shares Price (Range Per Share) ----------------- ----------------- ---------------------------------- Outstanding at January 1, 1996 - - - Granted 72,890 16.06 $16.06 Exercised - - - Canceled or expired - - - ----------------- Outstanding at January 1, 1997 72,890 16.06 16.06 Granted 90,475 16.30 16.25 to 17.06 Exercised (3,238) 16.06 16.06 Canceled or expired (1,342) 16.15 16.06 to 16.25 ----------------- Outstanding and exercisable at December 31, 1997 158,785 $16.20 $16.06 to $17.06 15. Related Party Transactions Asarco, a 54.1% stockholder of the Company, provides legal, tax, treasury and administrative support services to the Company. The amounts paid to Asarco for these services were $1.6 million, $0.8 million and $0.3 million in 1997, 1996 and 1995, respectively. 16. Concentration of Risk The Company operates two copper mines, a smelter and two refineries in Peru and substantially all of its assets are located there. There can be no assurances that the Company's operations and assets that are subject to the jurisdiction of the Government of Peru may not be adversely affected by future actions of such government. Substantially all of the sales of the Company's products are exported from Peru to customers principally in Europe, Asia, South America and the United States. In 1995, one customer represented 13% of net sales. A44 Financial instruments which potentially subject the Company to a concentration of credit risk consist primarily of cash and cash equivalents, marketable securities and trade accounts receivable. The Company invests or maintains available cash with various high-quality banks, principally in the U.S., Canada and Peru, or in commercial paper of highly rated companies. As part of its cash management process, the Company regularly monitors the relative credit standing of these institutions, and by policy, limits the amount of credit exposure to any one institution. At December 31, 1997, the Company had invested 19.7% of its cash equivalents and marketable securities with Peruvian banks, of which 41.3% of this amount was invested with one institution. During the normal course of business, the Company provides credit to its customers. Although the receivables resulting from these transactions are not collateralized, the Company has not experienced significant problems with the collection of receivables. The largest ten trade receivable balances accounted for 60.9% of the trade accounts receivable at December 31, 1997, of which one customer represented 12.2%. 17. Commitments and Contingencies Expansion and Modernization Project: In September 1996, the Company announced a two stage project which includes an expansion of the Cuajone mine and an expansion and modernization of the copper smelter at Ilo. Total capital cost for this project is estimated at $1.0 billion, budgeted to be spent over the next six years. The Cuajone mine expansion is expected to increase annual copper production by 130 million pounds at an estimated capital investment of $245 million. Construction contracts for the expansion have been awarded and site construction commenced in mid-1997 and completion of this stage of the expansion program is expected in early 1999. Engineering for the second stage of the program, the expansion and modernization of the Ilo smelter, began in 1997. Following completion of preliminary engineering, SPCC plans to modernize and increase the capacity of its existing copper smelter at Ilo. The expected cost of the second stage, based on the Company's preliminary engineering studies, is approximately $787 million and is expected to be completed in 2003. The Company has planned a third stage of the expansion and modernization plan, consisting of a second expansion at Cuajone and further expansion of the Ilo smelter capacity. The Company expects to consider a decision to proceed with this third stage in 1999, dependent on the availability of financing and other conditions at the time. The Company expects that the projects will be funded from a combination of existing cash, internally-generated funds and external financing. As a result of the $1 billion expansion program, electric power requirements will increase significantly, requiring the construction of substantial additional generating capacity. In the second quarter of 1997, the Company sold its existing power plant to an independent power company for $33.6 million. In connection with the sale, a power purchase agreement was also completed, under which the Company will purchase its power needs for the next twenty years. Under the agreement, cost of power will increase somewhat from its 1996 level, however, the company will avoid the significant capital expenditures that would be required to meet the needs of expanded operations and its power costs will be favorably affected by benefits available to independent power companies in Peru. A45 Environmental: As part of the 1991 Agreement, the Company has made a significant number of environmental capital expenditures, including a sulfuric acid plant at the Ilo smelter for partial recapture of emissions of sulfur dioxide, completed in 1995 at a cost of $103.0 million, a sewage treatment plant at Ilo, completed in 1994 at a cost of $2.0 million, and a tailings storage facility at Quebrada Honda, completed in 1996 at a cost of $40.8 million. The Company also has incurred capital costs of $3.0 million for environmental projects committed with the Ilo refinery acquisition in 1994. In addition, in April 1996 the Company began a $35 million expansion of the Ilo sulfuric acid plant. The expansion will increase the capture of sulfur dioxide emissions from the smelter from 18% to 30% and will also increase sulfuric acid production at the smelter to 330,000 tons per year in 1998, the expected year of expanded plant operation. Capital expenditures in connection with environmental projects were approximately $43.8 million in 1997. The Company's exploration, mining, milling, smelting and refining activities are subject to Peruvian laws and regulations, including environmental laws and regulations, which change from time to time. The Company's environmental compliance and management plan, PAMA, sets forth the investment to be made by the Company to comply with current Peruvian environmental regulations applicable to its operations. To implement the PAMA, the Company is required to make a minimum annual investment of 1% of net annual sales until compliance is met. The PAMA will require the Company to make significant additional capital expenditures to achieve compliance with the maximum permissible levels for its emissions and waste discharges (MPLs) within a period of five years, except for environmental controls applicable to its smelter operation which must be put in place within 10 years. The PAMA contemplates a number of environmental projects, the largest and most capital intensive of which is the planned modernization of the Ilo smelter. Management believes that under current Peruvian law and regulations, compliance with the PAMA will satisfy the MPL requirements pertaining to the Company's operations during the applicable five- or 10-year implementation period. The Company remains, however, subject to other environmental requirements applicable to its operations. Litigation: In April 1996, Southern Peru Limited, a wholly owned subsidiary of the Company, was served with a complaint filed in Peru by approximately 800 former employees seeking the delivery of a substantial number of labor shares of its Peruvian Branch plus dividends. In October 1997, the Superior Court of Lima nullified a decision of a court of first instance, which had been adverse to Southern Peru Limited. The Superior Court remanded the case for a new trial. Plaintiff filed an extraordinary appeal before the Peruvian Supreme Court. The Supreme Court may grant discretionary review in limited cases. The Supreme Court has not yet ruled as to whether it will accept the appeal. There is also pending against Southern Peru Limited a similar lawsuit filed by 127 additional former employees. In the third quarter of 1997, the court of first instance dismissed their complaint. The plaintiffs have appealed to the Superior Court of Lima. It is the opinion of management that the outcome of the legal proceedings mentioned, as well as other miscellaneous litigation and proceedings now pending, will not materially adversely affect the financial position of the Company and its consolidated subsidiaries. However, it is possible that litigation matters could have a material effect on quarterly or annual operating results, when they are resolved in future periods. A46 18. Summarized Financial Information of Significant Subsidiary The condensed consolidated financial information for Southern Peru Limited, a wholly owned subsidiary of Southern Peru Copper Corporation, included in the consolidated financial statements of the Company, is summarized below. Separate financial statements and other disclosures for Southern Peru Limited are not presented because management has determined that such information is not material to holders of Southern Peru Limited's debt securities.
