Part IV: Exhibit index is on page B1 through B3. A-1 PART I Item 1. Business THE COMPANY The Company is an integrated producer of copper which operates mining, smelting and refining facilities in the southern part of Peru. Southern Peru Copper Corporation was reorganized into a holding company structure effective January 2, 1996, upon completion of a public offer to exchange newly-issued Common Stock for outstanding labor shares of the Company's Peruvian Branch ("Labor Shares"). Effective December 31, 1998, the Company's predecessor and wholly-owned operating subsidiary, Southern Peru Limited, was merged into the Company. The Company, incorporated in 1952 was reorganized in 1955 and has conducted copper mining operations since 1960. Pursuant to Peruvian law, the Company conducts its operations in Peru through a registered branch (the "Branch"). The Branch is not a corporation separate from the Company. It is, however, an establishment, registered pursuant to Peruvian law, through which the Company holds assets, incurs liabilities and conducts operations in Peru. Although it has neither its own capital nor liability separate from that of the Company, it is deemed to have an equity capital for purposes of determining the economic interest of holders of labor shares. Labor shares are non-voting ownership interests distributed to workers in accordance with former Peruvian laws. The Branch comprises substantially all the assets and liabilities of the Company associated with its copper operations in Peru. Throughout this report, unless the context otherwise requires, the terms "Southern Peru", "SPCC" and "the Company" refer to the present corporation and its consolidated subsidiaries as well as its predecessor. In addition, throughout this report, unless otherwise noted, all tonnages are in short tons and all ounces are troy ounces. At December 31, 1998 the stockholders in the Company were ASARCO Incorporated (54.3%), Cerro Trading Company, Inc. (14.2%), Phelps Dodge Overseas Capital Corporation (14.0%) and common stockholders (17.5%). Reference is made to the following Financial Statement footnote included in this report: Net Sales in Note 5. CAUTIONARY STATEMENT Forward-looking statements in this report and in other Company statements include statements regarding expected commencement dates of mining or metal production operations, projected quantities of future metal production, anticipated production rates, operating efficiencies, costs and expenditures as well as projected demand or supply for the Company's products. Actual results could differ materially depending upon factors including the availability of materials, equipment, required permits or approvals and financing, the occurrence of unusual weather or operating conditions, lower than expected ore grades, the failure of equipment or processes to operate in accordance with specifications, labor relations, environmental risks as well as political and economic risk associated with foreign operations. Results of operations are directly affected by metals prices on commodity exchanges which can be volatile. Additional business information follows: COPPER BUSINESS The copper operations of the Company involve the mining, milling and flotation of copper ore to produce copper concentrates, the smelting of copper concentrates to produce blister copper and the refining of blister copper to produce copper cathode. A-2 The Company also produces refined copper using solvent extraction/electrowinning ("SX/EW") technology. Silver, molybdenum and small amounts of other metals are contained in copper ore as by-products. Silver sold is recovered in the refining process or as an element of blister copper. Molybdenum is recovered from copper concentrate in a molybdenum by-product plant. The Company has not reported information by industry segments because substantially all of its revenues are generated from its copper production. REVIEW OF OPERATIONS SPCC operates the Toquepala and Cuajone mines, high in the Andes, approximately 400 miles southeast of Lima. It also operates a smelter and refinery west of the mines at the Pacific Coast city of Ilo, Peru. SPCC is the largest mining company in Peru and one of the 10 largest private-sector copper mining companies in the world. OVERVIEW Mine copper production at SPCC declined in 1998 due to the impact of extended heavy rains and expected interruptions associated with the startup of the expanded concentrator at Cuajone. Smelter and refinery output increased, however, due to improved operating efficiencies and the treatment of purchased concentrates. Low-cost copper production from the SX/EW facility at Toquepala increased 6%, also as a result of improved operating practices. SPCC currently has a major, $1.2 billion expansion and modernization program underway that includes expansions of the Cuajone mine, the SX/EW facility at the Toquepala mine, and the Ilo smelter. The modernization project at Ilo will use flash smelting and flash converting technology to increase production capacity and enhance environmental controls. Expansion of the mill at the Cuajone mine was completed in 1998 and commissioning is in progress. Modernization of the mining equipment at Cuajone will continue for another two years. Engineering began on modernization and expansion of the Ilo smelter. The expansion program at Cuajone and Ilo will further improve productivity, reduce operating costs, increase copper production and is expected to significantly increase the capture of sulfur dioxide to in excess of 99%. MINING OPERATIONS Total mined copper production at SPCC decreased 2.8% in 1998, compared with 1997, due to lower production at Cuajone. Cuajone production decreased 7% in 1998 to 316 million pounds due principally to production interruptions during the integration of the expansion at the concentrator and the impact of heavy rains. Normal startup delays at the concentrator reduced concentrate production at Cuajone during the year. Concentrator throughput for the year was 21.7 million tons of ore producing 570 thousand tons of copper concentrates. Flooding and power interruptions hampered mining early in 1998 but the mine recovered later in the year and fourth quarter 1998 production was 8% greater compared with the same period of the prior year. Toquepala mine production for the year was 247 million pounds equaling 1997 production. The Toquepala concentrator milled 18.0 million tons of ore. Together, the two mines produced 2.9 million ounces of silver and 9.6 million pounds of molybdenum as by-products. A-3 New drills, trucks and a shovel were added at the Cuajone mine in 1998 and older, less efficient equipment was retired. As part of the Cuajone expansion project, two grinding mills, flotation equipment, a vertical regrind mill, pressure filters, a reclaimed water pumping station and other enhancements were added to the Cuajone concentrator. SX/EW OPERATIONS The SX/EW facility at Toquepala produces refined copper from solutions obtained by leaching low-grade ore stored at the Toquepala and Cuajone mines. Higher than anticipated production through most of the year offset production losses from the first quarter when the operations were hampered by power interruptions and flooding. The facility produced 5.9 million pounds more copper in 1998 than in 1997. The SX/EW plant obtained registration during the year from the New York Commodity Exchange (COMEX), certifying cathode quality and complementing certification previously obtained from the London Metal Exchange (LME). ORE RESERVES SPCC identified substantial additional mineralized material in 1996 and continues to evaluate the extent of those resources. At year-end 1998, proven and probable sulfide reserves totaled 1,401 million tons with an average copper grade of 0.64% at Cuajone and 295 million tons with an average copper grade of 0.83% at Toquepala. An additional 209 million tons of mineralized material at an average copper grade of 0.56% at Cuajone and 330 million tons at an average copper grade of 0.65% at Toquepala still are being evaluated. Further drilling is also underway at Toquepala to define and identify additional, deeper reserves. In addition, the Company has 794 million tons of leachable, low-grade ore that can be processed economically by the SX/EW operation. SMELTING AND REFINING OPERATIONS The Ilo smelter increased its production of blister copper by 1% compared with 1997 by treating concentrates with higher copper contents. The smelter increased its purchase of concentrates from others to offset decreased concentrate production primarily at Cuajone. Improved productivity at the smelter offset the effect of production curtailments under the Company's Supplemental Control Program (SCP) to control emissions from the smelter. SPCC's total refined copper production, including the 104.0 million pounds from the SX/EW plant, increased 6% to 647.4 million pounds in 1998 from 611.5 million pounds in 1997. Refined production from the Ilo refinery reached 543.4 million pounds in 1998. SPCC has spent $20.0 million in recent years to modernize the Ilo refinery, which was purchased in 1994 from a Peruvian government-owned entity. Installation of acid-resistant polymer cells and a new rectifier in the tank house increased capacity by almost 30% to 540 million pounds of copper cathode per year. SPCC's Ilo smelter provides feed for the refinery. Blister copper produced by the smelter exceeds the refinery's capacity and the excess is sold to other refineries around the world. EXPANSION AND MODERNIZATION PROGRAM Excellent progress is being made on the $1.1 billion expansion and modernization program originally announced by the Company in 1996. The major expansion of the Cuajone mine and expansion and modernization of the Ilo smelter will increase copper production and is expected to improve the sulfur dioxide capture rate to over 99%. A-4 Most of the $245 million Cuajone mine expansion was completed in 1998. Acquisition of new mining equipment will continue for the next two years. The expansion will increase mined copper output at Cuajone by 130 million pounds per year, increasing the Company's total production by 19%. New equipment and processes were installed at the Cuajone concentrator in 1998, testing and calibration continues and the expanded facility is expected to reach design rates of production by the end of the first quarter of 1999. Engineering for the modernization and expansion of the Ilo smelter began during the year. The $875 million Ilo smelter project consists of installation of a new single line flash smelting furnace and a single line flash converting furnace to process 1.25 million tons of concentrate per year. The project is designed so that the smelter's existing furnaces can continue to operate while the new flash furnaces are brought on-line, enabling SPCC to maintain normal production during the new facilities' startup period. The Company's use of flash converting technology will provide significant material handling advantages and will permit improved capture of sulfur dioxide. When the smelter modernization is complete, the smelter is expected to have a sulfur capture rate in excess of 99% and will meet or exceed current Peruvian standards and international environmental guidelines. Permits were received late in the year to proceed with construction of the Torata River Flood Control Project. To divert the Torata River around the proposed Cuajone pit expansion, SPCC will construct a dam and approximately eight kilometers of tunnel and pipelines. The project will protect the expanded pit from flooding during major storm events, alleviate periodic flooding for neighbors down-river from the mine and make a portion of the current river valley available for placement of mine waste material. Field construction activities for the $75.5 million project are scheduled to begin this year with completion scheduled for 2001. A third stage of the expansion and modernization program is under consideration which includes an additional expansion of the Cuajone mine and further expansion of the Ilo smelter. Additional mining equipment and a new SAG mill would be added at Cuajone to increase total annual copper production by 240 million pounds, or 30% of total production. The decision to proceed with the third stage expansion will be based on copper prices, availability of financing and completion of the current program. When all of the expansion projects are completed, SPCC will produce 930 million pounds of copper per year, or 1.4 times 1998 production. EXPLORATION SPCC has an active exploration program focusing on copper and gold-bearing properties. The Company currently has rights to conduct exploration on over 275,000 hectares of land in Peru. The Tantahuatay project, owned 44% by SPCC, has focused on defining a shallow, heap-leachable gold oxide resource, underlaid by a large, disseminated, copper-gold sulfide resource. Preliminary studies are being conducted to determine the viability of developing the gold resource. Several other copper and gold projects, wholly owned by the Company, were drilled in 1998 and show encouraging results. Those projects continue to be evaluated. SPCC's exploration activities are independent from exploration activities of its founding shareholders. A-5 ENVIRONMENT In addition to the expansion and modernization of the Ilo smelter, Southern Peru continues to install new facilities and implement new operating procedures to further reduce the impact of its operations on the environment. An expansion of the Ilo smelter acid plant commenced operations during the first quarter of 1998, capturing all of the off-gases from the Modified El Teniente Converter (CMT), or 30% of the smelter's total emissions. The original sulfuric acid plant, completed in 1995, captured 60% of the CMT off-gases, or 18% of the smelter's total emissions. With the addition, the acid plant produced 307,100 tons of sulfuric acid in 1998. Part of the acid produced is used by the Company to leach ore at its SX/EW operation; the balance is sold in regional markets. Southern Peru also uses its SCP to control sulfur dioxide emissions by curtailing production during periods of adverse weather. The acid plants and the SCP program have been effective in improving air quality in the Ilo area. PRINCIPAL PRODUCTS AND MARKETS The principal uses of copper are in the building and construction industry, electrical and electronic products and, to a lesser extent, industrial machinery and equipment, consumer products and the automotive and transportation industries. Silver is used for photographic, electrical and electronic products and, to a lesser extent, brazing alloys and solder, jewelry, coinage, silverware and catalysts. Molybdenum is used to toughen alloy steels and soften tungsten alloy and is also used in fertilizers, dyes, enamels and reagents. During 1998, 1997, and 1996, substantially all of the Company's copper production was exported from Peru and sold to customers in Europe, the Far East, the United States and elsewhere in Latin America. A substantial portion of SPCC's copper sales is made under annual contracts to industrial users. Silver is sold under annual contracts or in spot sales and molybdenum is sold in concentrate form to merchants and other refiners under annual contracts. Most customers receive shipments on a monthly basis at a constant volume throughout the year. As a result there is little seasonality in SPCC sales volumes. BACKLOG OF ORDERS Substantially all of the Company's metal production is sold under annual contracts. To the extent not sold under annual contracts, production can be sold on commodity exchanges or in spot sales. Final sales values are determined based on prevailing commodity prices for the quotation period, generally being the month of, the month prior to or the month following the actual or contractual month of shipment or delivery according to the terms of the contract. COMPETITIVE CONDITIONS Competition in the copper market is principally on a price and service basis, with price being the most important consideration when supplies of copper are ample. The Company's products compete with other materials, including aluminum and plastics. EMPLOYEES At December 31, 1998 the Company employed 4,557 persons, about fifty-five percent of whom were covered by labor agreements with nine labor unions. There were no labor strikes in 1998. A-6 ENERGY MATTERS AND WATER RESOURCES Electric power for the Company's operating facilities is generated by a thermal electric plant owned and operated by Enersur S.A. and located adjacent to the Ilo smelter. Power generation capacity is currently 150 megawatts. In addition, the Company has 30 megawatts of power generation capacity from waste heat boilers in the smelter and two small hydro-generating installations at Cuajone. Power is distributed over a 139-mile, closed loop transmission circuit. In 1997, the Company sold its Ilo power plant to Enersur S.A. and entered into a 20-year power purchase agreement. The power purchase agreement contains provisions obligating Enersur S.A. to construct additional capacity upon notice to meet the Company's increased electricity requirements from the planned expansion and modernization. The parties also entered into an agreement for the sharing of certain services between the power plant and the Company's smelter at Ilo. Under this agreement, the Company's cost of power will increase somewhat from its 1996 level, while the Company will benefit by avoiding significant capital expenditures that would be required to meet the needs of the expanded operations. SPCC has water concessions for well fields at Huaitire and Titijones and surface water rights from Lake Suches. ENVIRONMENTAL MATTERS The Company anticipates spending $75.9 million for environmental control capital expenditures in 1999. Capital expenditures in connection with environmental projects were approximately $25.3 million in 1998, $47.8 million in 1997 and $24.6 million in 1996. See "Management's Discussion and Analysis of Financial Condition and Results of Operation - Environmental Matters" which is herein incorporated by reference. CONCESSIONS The Company has concessions from the Peruvian government for its exploration, exploitation, extraction and/or production operations (collectively, the "Concessions"). The Concessions are in full force and effect under applicable Peruvian laws, and the Company believes it is in compliance with all material terms and requirements applicable to the Concessions. The Concessions have indefinite terms, subject to payment by SPCC of concession fees of up to $2 per hectare annually for the mining concessions and a fee based on nominal capacity for the processing concessions. Fees paid during 1998 were approximately $273,000. REPUBLIC OF PERU Substantially all of the Company's revenues are derived from the Toquepala mine, the Cuajone mine, the SX/EW facility and the smelter and refinery at Ilo, all of which are located within a 30-mile radius in the southern part of Peru. Risks attendant to the Company's operations in Peru include those associated with economic and political conditions, effects of currency fluctuations and inflation, effects of government regulations and the geographic concentration of the Company's operations. A-7 Item 2. Properties FACILITIES The Company's principal executive offices are located at 180 Maiden Lane, New York, New York 10038 and Avenida Caminos del Inca No. 171, Chacarilla del Estanque, Santiago de Surco, Lima 33, Peru. At December 31, 1998, the Company, through its Peruvian Branch, has 100% interest in the Toquepala and Cuajone mines, the SX/EW facility, the Ilo smelter, the sulfuric acid plant and the Ilo refinery and operates them pursuant to concessions from the Peruvian Government. See Item 1 "Business--Concessions". The Company owns, through the Branch, its offices in Lima. Its offices in New York are located in space leased to it by Asarco.

Management's Discussion and Analysis of Financial Condition and Results of Operations OVERVIEW The Company's business is affected by the factors outlined below which should be considered in reviewing the financial position, results of operations and cash flows of the Company for the periods described herein. Inflation and Devaluation of the Peruvian Sol: A portion of the Company's operating costs are denominated in Peruvian soles. Since the revenues of the Company are primarily denominated in U.S. dollars, when inflation in Peru is not offset by a corresponding devaluation of the sol, the financial position, results of operations and cash flows of the Company could be adversely affected. The value of the net assets of the Company denominated in soles can be affected by devaluation of the sol. The recent inflation and devaluation rates are as follows: Years ended December 31, 1998 1997 1996 ---- ---- ---- Peruvian Inflation Rate 6.0% 6.5% 11.8% Sol/Dollar Devaluation Rate 15.7% 4.9% 12.1% Peruvian Branch: The consolidated financial statements included herein are prepared in U.S. dollars and in accordance with generally accepted accounting principles in the United States (US GAAP). The Peruvian Branch (the Branch) consists of substantially all the assets and liabilities of Southern Peru Copper Corporation (SPCC) associated with its copper operations in the Republic of Peru. The Branch is registered with the Peruvian government as a branch of a foreign mining company. The results of the Branch are consolidated in the financial statements of the Company. The Branch maintains its books of account in soles, prepares financial information in accordance with generally accepted accounting principles in Peru (Peruvian GAAP). Peruvian GAAP requires the inclusion in the financial statements of the Branch of the Resultado por Exposicion a la Inflacion (Result of Exposure to Inflation), which seeks to account for the effects of inflation by adjusting the value of non-monetary assets and liabilities and equity by a factor corresponding to wholesale price inflation rates during the period covered by the financial statements. Monetary assets and liabilities are not so adjusted. 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 $1.1 billion, budgeted to be spent through the year 2003. Most of the $245 million Cuajone mine expansion was completed in 1998. Acquisition of new mining equipment will continue for the next two years. When completed, the expansion will increase mined copper output at Cuajone by 130 million pounds per year, or 19% of the Company's total production. Throughput at the concentrator increased in December and is expected to reach design levels in the first quarter of 1999. Testing and calibration of the expanded facilities are ongoing and the Company officially inaugurated the project in March 1999. A-17 The second stage of the program, the expansion and modernization of the Ilo smelter will consist of installation of a new single line flash smelting furnace and a single line flash converting furnace to process 1.25 million tons of concentrate per year. A major advantage incorporated into the project is the ability to operate existing furnaces while the new flash furnaces are brought on-line, thereby minimizing production disruptions during the startup period of the new facilities. The Company has decided to use flash converting technology rather than conventional Peirce Smith converters because flash converting provides significant material handling advantages and achieves improved sulfur capture. When the modernization program is completed, the smelter is expected to have a sulfur capture rate in excess of 99% and to meet or exceed current international environmental guidelines. The estimated cost of the project is $875 million and is expected to be completed by 2003. In 1998, the Company commenced a $48 million project to expand annual SX/EW copper production by 26 million pounds. Engineering design is underway and equipment purchases are being made. The project is on schedule and completion is expected in the third quarter of 1999. Late in the year, the Peruvian government approved the Company's Torata River Control Project. The project will divert the Torata River around the Cuajone mine pit expansion. The $75.5 million project will commence in 1999 and is scheduled for completion in 2001. An optional third stage of the expansion and modernization program, would include a second expansion at Cuajone and further expansion of the Ilo smelter capacity. Consideration of whether to proceed with this third stage is dependent on copper prices, the availability of financing and other conditions at the time of decision. The Company expects that the projects will be funded from a combination of existing cash, internally generated funds and external financing. RESULTS OF OPERATIONS FOR THE YEARS ENDED DECEMBER 31, 1998, 1997 AND 1996 SPCC reported 1998 net earnings of $54.6 million, or diluted earnings per share of 68 cents, compared with net earnings of $185.7 million, or diluted earnings per share of $2.32 in 1997 and net earnings of $180.5 million, or diluted earnings per share of $2.25 in 1996. The decline in net earnings in 1998 compared with 1997 is primarily a result of lower copper prices. The average price of copper in 1998 on the London Metal Exchange declined 28 cents per pound from 1997 to 75 cents per pound, and at year end 1998 was 66 cents per pound. In addition to lower metal prices, results for 1998 also reflect an increase in the effective income tax rate compared to 1997. The earnings decrease was partially offset by savings realized from the cost reduction program instituted by the Company in 1998. In April 1998, SPCC initiated cost-reduction and production enhancement programs, including reductions in operating expenses, purchased services and general and administrative expenses, designed to reduce annual expense by $30 million when fully implemented. The program is estimated to have increased pre-tax earnings by $25.7 million in 1998, improving net after-tax earnings by $15.8 million, or 20 cents per share. In 1999, the program is expected to improve net earnings by $17 million, or 21 cents per share. In connection with the cost reduction program the Company recorded a $10 million pre-tax charge in the first quarter of 1998 for severance costs. In addition, in the fourth quarter of 1998 the Company transferred title to a major portion of the Ilo townsite to its worker occupants and the City of Ilo. Titles to 1,344 individual homesites were transferred. The Company recorded a pre-tax charge of $10.9 million in 1998 to write-off the remaining book value of the transferred A-18 property and to provide for other costs associated with the divestiture. The Company expects future savings as a result of the transfer of the townsite through reduced maintenance costs. The improvement in net earnings in 1997 compared with 1996 was largely the result of a lower effective income tax rate, offset in part by higher power costs. In 1997, the Government of Peru approved a reinvestment allowance for the Company's program to expand the Cuajone mine. Pursuant to the reinvestment allowance, the Company receives certain tax incentives in Peru. As a result, U.S. tax credit carryforwards for which no benefit had previously been recorded were utilized. Principally because of the reinvestment program, the Company's effective tax rate was lower in 1997, compared with the prior year, increasing net earnings by approximately $14.7 million. As a result of the expansion program, electric power requirements will increase significantly requiring the construction of 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 agreed to purchase its power needs for twenty years. Under the agreement, the 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. Net Sales: Net sales in 1998 were $627.9 million, compared with $814.2 million in 1997 and $753.0 million in 1996. Sales decreased in 1998 by $186.3 million, largely as a result of lower copper prices, offset somewhat by an increase in copper and molybdenum volume. Copper sales volume was 8.1 million pounds higher in 1998 compared with 1997. Sales of copper produced at Company mines, however, decreased by 6.5 million pounds in 1998 as compared with 1997. Copper sales volume was 49.7 million pounds higher in 1997 compared with 1996. Of this increase, 46.4 million pounds were from purchased concentrates. At December 31, 1998, the Company has recorded sales of 27.5 million pounds of copper at a provisional price of 66 cents per pound. These sales are subject to final pricing based on the average monthly LME copper price in the month of settlement which will occur in the first quarter of 1999. Prices: Sales prices for the Company's metals are established principally by reference to prices quoted on the London Metal Exchange (LME), the New York Commodity Exchange (COMEX) or published in Platt's Metals Week for dealer oxide mean prices for molybdenum products. Price/Volume Data 1998 1997 1996 ---- ---- ---- Average Metal Prices Copper (per pound - LME) $0.75 $1.03 $1.04 Molybdenum (per pound - Metals Week Dealer Oxide Mean) $3.41 $4.30 $3.78 Silver (per ounce - COMEX) $5.51 $4.88 $5.18 Sales Volume (in thousands) Copper (pounds) 752,114 743,984 694,290 Molybdenum (pounds)(1) 9,677 9,398 8,813 Silver (ounces) 3,288 3,086 3,110 (1) The Company's molybdenum production is sold in concentrate form. Volume represents pounds of molybdenum contained in concentrates. A-19 Financial Instruments: The Company uses 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. Earnings include pre-tax gains from option sales and exercises of $7.2 million in 1998, $10.2 million in 1997 and $9.9 million in 1996. At December 31, 1998, the Company held no copper put options. 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 as a component of cost of sales. As of December 31, 1998 and 1997, the Company has entered into the following fuel swap agreements: Weighted Average Contract Quantity Price Fuel Type Period (Barrels) (per Barrel) - ------------------ --------------------- ---------------- -------------------- 1998 Residual Oil 1/99-9/99 1,095,000 $ 9.84 Diesel Fuel 1/99-9/99 432,000 $15.80 1997 Residual Oil 1/98-12/98 540,000 $13.57 Diesel Fuel 1/98-12/98 200,000 $21.17 In the event of a hypothetical 10 percent decrease in the respective fuel prices, the Company would incur higher production costs in 1999 of approximately $3.2 million over the life of the contracts than it would have incurred had the exposure not been hedged. In 1998, the Company's production costs would have been $3.3 million lower if this exposure had not been hedged. Cost of Sales: Cost of sales was $442.2 million in 1998 compared with $474.4 million in 1997 and $400.7 million in 1996. The decrease of $32.2 million in 1998 includes the lower cost of copper processed and sold from purchased concentrates, the lower unit cost of company mined copper as a result of decreases in power and fuel costs, and benefits from the Company's cost reduction program. These decreases were offset in part by a $10 million charge for severance costs and a A-20 $10.9 million charge for Ilo townsite divestiture costs, which were part of the Company's earnings enhancement program. The increase of $73.7 million in 1997 was principally due to the higher sales volume of copper produced from purchased concentrates and higher power costs. Other Expenses: Depreciation and depletion expense was $60.9 million in 1998, compared with $46.7 million in 1997 and $41.6 million in 1996. The increase in 1998 includes depreciation of the tailings dam facility completed in late 1997, the acid plant expansion completed in 1998 and the addition of haul trucks in 1998 and 1997. The increase in 1997 reflects depreciation of the refinery expansion program completed in late 1996, and the addition of haul trucks and other mobile equipment. Exploration expense was $5.2 million, $7.4 million and $5.1 million, in 1998, 1997 and 1996, respectively. The increase in 1997 reflects an acceleration of drilling programs at the Company's exploration properties. Non-Operating Items: Interest income was $15.8 million in 1998 compared with $20.9 million in 1997 and $18.3 million in 1996. The decrease in 1998 is because of lower invested balances as funds were utilized in the Company's expansion program. The increase in 1997 reflects higher invested cash balances partially offset by lower interest rates. Interest income is expected to decrease as available cash is used to fund the Company's expansion and modernization program. Other income was $9.8 million in 1998 compared with $7.1 million in 1997 and $4.5 million in 1996. Other income in 1998 includes a $5.3 million insurance settlement related to flood damage which occurred in 1997. Total interest expense was $25.6 million in 1998, compared with $21.9 million in 1997 and $12.5 million in 1996. Increased interest expense in 1998 and 1997 reflect the cost of additional borrowings in connection with the Company's expansion program. In 1998 and 1997, the Company capitalized $10.6 million and $2.3 million of interest, respectively, principally related to expenditures on the expansion program. Taxes on Income: Taxes on income were $25.6 million, $55.6 million and $80.2 million for 1998, 1997 and 1996, respectively, and include $22.9 million, $45.0 million and $74.9 million of Peruvian income taxes and $2.7 million, $10.6 million and $5.3 million, for U.S. federal and state taxes for 1998, 1997 and 1996, respectively. U.S. income taxes are primarily attributable to investment income as well as limitations on use of foreign tax credits in determining the alternative minimum tax. In 1997, the Government of Peru approved a reinvestment allowance for the Company's program to expand the Cuajone mine. The reinvestment allowance provides the Company 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 Company's effective tax rate, as a result of the reinvestment allowance, lowered tax expense by approximately $14.7 million in 1997. Pursuant to the reinvestment allowance the Company receives 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 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 A-21 current Peruvian law, the Company is entitled to use the credits against its Peruvian income tax liability or to receive a refund. Minority Interest of Labor Shares: The minority interest of labor shares was $0.5 million in 1998, compared to $4.4 million in 1997 and $5.2 million in 1996. The provision for minority interest of labor shares represents an accrual of 2.0%, 2.4% and 3.1% for 1998, 1997 and 1996, respectively, of the Branch's after-tax earnings. The reductions in the percentage of minority interest of labor shares in 1998 and 1997 is a result of purchases of labor shares by the Company. Cash Flows - Operating Activities: Net cash provided from operating activities was $181.4 million in 1998, compared with $277.6 million in 1997 and $158.4 million in 1996. The decrease in 1998 was primarily attributable to lower copper prices. The decrease in 1998 reflects lower earnings of $131.1 million partially offset by higher depreciation and deferrred tax provisions of $14.1 million and $21.7 million, respectively. The increase in 1997 reflects higher earnings of $5.1 million, higher depreciation of $5.1 million and changes in operating assets and liabilities. The increase in cash provided from operating assets and liabilities reflects a decrease in trade accounts receivable due to the decline in copper prices in the final months of 1997 and a reduction in the Company's income tax payments, due to the reinvestment allowance in Peru. Cash Flows - Investing Activities: Net cash used for investing activities was $70.7 million in 1998, compared with $337.6 million in 1997 and $79.4 million in 1996. Capital expenditures in 1998 were $258.7 million, compared with $184.0 million in 1997 and $120.8 million in 1996. The increase in capital expenditures in 1998 from 1997 reflects the expansion project at the Cuajone mine and the Ilo smelter modernization program as well as increased capitalization of mine stripping. Other investment activities in 1998 include net proceeds of $182.4 million from held-to-maturity investments. The increase in 1997 capital expenditures reflects $51.1 million for the Cuajone mine expansion and $14.4 million for a new gas turbine, which was later sold with the Company's Ilo power plant. The Company's planned capital expenditures in 1999 are estimated to be approximately $285 million, which includes expenditures related to the completion of the expansion of the Cuajone mine, completion of the SX/EW plant expansion, the Torata River Flood Control project and the Ilo smelter modernization. Cash Flows - Financing Activities: Financing activities used cash of $59.5 million in 1998 compared with providing cash of $11.8 million in 1997 and a use of cash of $127.3 million in 1996. Included in 1998 activity are debt repayments of $13.7 million, and purchases of labor shares and net treasury stock transactions of $3.8 million and $2.7 million, respectively. Included in 1997 are proceeds from the sale of $150 million of Secured Export Notes (SENS) and the placement of $50 million of bonds in the Peruvian market. Debt repaid in 1997 was $58.7 million, including the prepayment of a $35.0 million loan from Mitsui & Co., Ltd. In 1997, purchases of labor shares and treasury stock were $8.9 million and $1.7 million, respectively. On February 2, 1999 a dividend of $0.03 a share, totaling $2.4 million was declared, payable March 3, 1999. It has been the Company's policy to distribute approximately 50% of net earnings as dividends. A-22 LIQUIDITY AND CAPITAL RESOURCES Financing: In 1997, the Company entered into a $600 million seven year loan facility with a group of international financial institutions. The facility consists of a $400 million term loan and a $200 million revolving credit line. 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, 1998. Also, in 1997, the Company privately placed $150 million SENS in the United States and international markets. These notes, which have been registered with the Securities and Exchange Commission, have 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 1997, the Company sold $50 million of bonds, due June 2004 to investors in Peru. The bonds have a fixed interest rate of 8.25%. The Company expects that it will meet its cash requirements for 1999 and beyond from internally generated funds, cash on hand, borrowings under the seven-year loan facility signed in April 1997, and from additional external financing. The Company also has a loan outstanding with Corporacion Andina de Fomento (CAF) of $19.6 million with interest based on LIBOR and an outstanding loan from the United States Export - Import (EXIM) Bank of $14.6 million, with interest at a 6.43% fixed rate. Both loans are payable in semi-annual installments through 2001. At December 31, 1998, the Company had outstanding borrowings of $234.2 million, compared with $247.9 million at December 31, 1997. Certain 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 the net income of the Company for any fiscal quarter as long as such dividends are paid by June 30 of the following year. Net assets of the Company unavailable for the payment of dividends totaled $1,106 million at December 31, 1998. In accordance with the most restrictive covenant of the Company's loan agreements, additional indebtedness of $874.4 million would have been permitted at December 31, 1998. The EXIM Bank credit agreement is collateralized by pledges of receivables from 7,700 tons of copper per year. The CAF loan is collateralized by liens on the SX/EW facility. The SENS 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 SENS 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 collections 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, 1998. Included in Other assets are $11.2 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. At December 31, 1998, the Company's debt as a percentage of total capitalization (the total of debt, minority interest of labor shares and stockholders' equity) was 17.2% as compared with 18.2% at December 31, 1997. A-23 At December 31, 1998, the Company's cash and marketable securities amounted to $198.1 million compared with $331.1 million at December 31, 1997. DIVIDENDS AND CAPITAL STOCK The Company paid dividends to stockholders of $40.7 million, or $0.51 per share, in 1998, $101.1 million, or $1.26 per share, in 1997 and $117.9 million, or $1.47 per share in 1996. Distributions to the labor share minority interest were $0.9 million, $2.5 million and $4.1 million in 1998, 1997 and 1996, respectively. At the end of 1998 and 1997, the authorized and outstanding capital stock of the Company consisted of 65,900,833 shares of Class A common stock, par value $0.01 per share; and 34,099,167 authorized shares of common stock, par value $0.01 per share, of which 13,949,812 were outstanding at December 31, 1998 and 14,157,107 shares were outstanding at December 31, 1997. ENVIRONMENTAL MATTERS 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, approved in January 1997, 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 within a period of five years, except for environmental controls applicable to its smelter operation which must be put in place within ten 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. See "Management's Discussion and Analysis of Financial Condition and Results of Operations - Expansion and Modernization Project." Under current Peruvian law and regulations, compliance with the PAMA will satisfy environmental requirements pertaining to the Company's operations during the applicable five-or-ten year implementation period. The Company remains, however, subject to other environmental requirements applicable to its operations. Environmental capital expenditures were $25.3 million, $47.8 million and $24.6 million in 1998, 1997 and 1996, respectively. In addition, the Company estimates spending $75.9 million for environmental control capital expenditures in 1999. YEAR 2000 The Company has implemented a three phase program to identify and resolve Year 2000 (Y2K) issues related to the integrity and reliability of its computerized information systems as well as computer systems embedded in its production processes. Phase one of the Company's program which involved an assessment of Y2K compliance of the Company's computerized information systems and embedded computer systems has been completed. In phase two of the program the Company is modifying or replacing all non-compliant systems. The Company has identified two computerized information systems that are not Y2K compliant. These systems are being replaced and are expected to be operational by the second quarter of 1999. In addition, the Company has identified one embedded computer system that is not Y2K compliant. This system is being replaced and is expected to be operational in the third quarter of 1999. As of December 31, 1998, approximately 60% of the Company's computerized information systems have been tested and are Y2K compliant A-24 with the remainder expected to be tested and be Y2K compliant by the second quarter of 1999. The Company continues to test these systems where appropriate. In addition, the Company continues to test its computer systems embedded in the production processes and expects to be completed and Y2K compliant by the third quarter of 1999. As of December 31, 1998, the Company had spent approximately $0.9 million in addition to its normal internal information technology costs in connection with its Y2K program. The Company expects to incur additional costs of $0.3 million to complete phases two and three of the program. Under the third phase of the program the Company has sent detailed information requests to its principal customers, suppliers and service providers to determine the status of their Y2K compliance. As of December 31, 1998, the Company received confirmations from approximately 50% indicating that they are or will be Y2K compliant. The Company expects to have further communications with those who have not responded or have indicated further work was required to achieve Y2K compliance. The third phase of the program is expected to be completed in the first quarter of 1999. Among other things, the Company's operations depend on the availability of utility services, principally electricity, and reliable performance by international transportation services. A substantial disruption in any of these services due to providers of these services failing to achieve Y2K compliance would have an adverse impact on the Company's financial results the significance of which would depend on the length and severity of the disruption. In response to a request from the Company, a detailed plan to ensure Y2K compliance by the Company's principal electrical power supplier was received. The Company is monitoring the progress of this plan. The Company will complete a contingency plan for each of its principal operations during the second quarter of 1999. The purpose of the contingency plan is to identify possible alternatives which could be used in the event of a disruption in the delivery of essential goods or services and to minimize the effect of such a disruption. The above estimates and conclusions contain forward-looking statements and are based on management's best estimate of future events. Actual results could differ materially depending on the availability of resources and the Company's ability to identify and correct all Y2K issues. IMPACT OF NEW ACCOUNTING STANDARDS In March 1998, the American Institute of Certified Public Accountants' Accounting Standards Executive Committee issued statement of Position No. 98-1 "Accounting for the Cost of Computer Software Developed or Obtained for Internal Use." This statement which is effective for fiscal years beginning after December 15, 1998, provides guidance on accounting for the costs of computer software developed or obtained for internal use. This statement will not have a material impact on the Company's financial statements. In June 1998, the Financial Accounting Standards Board issued SFAS No. 133 "Accounting for Derivative Instruments and Hedging Activities". This statement which is effective for fiscal years beginning after June 15, 1999, establishes accounting and reporting standards for derivative instruments and hedging activities. The Company is currently assessing the impact of this statement. A-25 CAUTIONARY STATEMENT Forward-looking statements in this report and in other Company statements include statements regarding expected commencement dates of mining or metal production operations, projected quantities of future metal production, anticipated production rates, operating efficiencies, costs and expenditures as well as projected demand or supply for the Company's products. Actual results could differ materially depending upon factors including the availability of materials, equipment, required permits or approvals and financing, the occurrence of unusual weather or operating conditions, lower than expected ore grades, the failure of equipment or processes to operate in accordance with specifications, labor relations, environmental risks as well as political and economic risk associated with foreign operations. Results of operations are directly affected by metals prices on commodity exchanges which can be volatile. A-26 Item 8. Financial Statements and Supplementary Data.

A-30 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 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. Revenue is recognized primarily in the month product is shipped to customers based on prices as provided in sales contracts. When the price is not determinable at the time of shipment to customers, revenue is recognized based on prices prevailing at the time of shipment with final pricing generally occurring within three months of shipment. Revenues with respect to these sales are adjusted in the period of settlement to reflect final pricing and in periods prior to settlement to reflect any decline in market prices which may occur between shipment and settlement. The Company sells copper in blister and refined form at industry standard commercial terms. Net sales include the invoiced value of copper, silver, molybdenum, acid, 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 the lower of 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. Any 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. A-31 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. Hedging Activities: Derivative instruments may be used to manage exposure to market risk from changes in commodity prices, interest rates or the value of the Company's assets and liabilities. 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. The Company may purchase put options or create synthetic 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. Swap Agreements: Fuel swap agreements limit the effect of changes in the price of fuel. The differential to be paid or received as fuel prices change is recorded as a component of cost of sales. Stock Based Compensation: The Company applies the disclosure only provisions of Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based Compensation." Impact of New Accounting Standards: In March 1998, the American Institute of Certified Public Accountants' Accounting Standards Executive Committee issued Statement of Position No. 98-1 "Accounting for the Cost of Computer Software Developed or Obtained for Internal Use." This statement which is effective for fiscal years beginning after December 15, 1998, provides guidance on accounting for the costs of computer software developed or obtained for internal use. This statement will not have a material impact on the Company's financial statements. In June 1998, the Financial Accounting Standards Board issued SFAS No. 133 "Accounting for Derivative Instruments and Hedging Activities". This statement which is effective for fiscal years beginning after June 15, 1999, establishes accounting and reporting standards for derivative instruments and hedging activities. The Company is currently assessing the impact of this statement. 2. Merger of Subsidiary Company Southern Peru Copper Corporation was reorganized into a holding company structure effective January 2, 1996, upon completion of a public offer to exchange newly-issued Common Stock for outstanding labor shares of the Company's Peruvian Branch. Effective December 31, 1998, the Company's predecessor and wholly-owned operating subsidiary, Southern Peru Limited, was merged into the Company. A-32 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 and (losses) resulting from foreign currency transactions are included in "Cost of sales" and amounted to ($3.0) million, $2.0 million and $6.7 million in 1998, 1997 and 1996, respectively. 4. Taxes on Income The components of the provision for taxes on income are as follows: For the years ended December 31, 1998 1997 1996 ---- ---- ---- (in millions) U.S. Federal and state Current $ 2.2 $ 10.2 $ 5.0 Deferred 0.5 0.4 0.3 ------------ --------------- --------------- U.S. Federal and state 2.7 10.6 5.3 ------------ --------------- --------------- Foreign: Current 8.5 52.3 62.9 Deferred 14.4 (7.3) 12.0 ------------ --------------- --------------- Foreign 22.9 45.0 74.9 ------------ --------------- --------------- Total provision for income taxes $25.6 $ 55.6 $80.2 ============ =============== =============== Total taxes paid were $10.4 million, $30.1 million and $123.4 million in 1998, 1997 and 1996, respectively. Reconciliation of the statutory income tax rate to the effective income tax rate is as follows: For the years ended December 31, 1998 1997 1996 ---- ---- ---- 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 (20.8) (16.9) (25.3) Peruvian reinvestment allowance - (9.0) - Alternative minimum tax (AMT) credit - (3.4) - Percentage depletion (10.5) (9.6) (9.0) Income not taxable in Peru (1.8) (2.6) (1.8) Other (0.2) (0.9) 1.3 ---------- --------- --------- Effective income tax rate 31.7% 22.6% 30.2% ========== ========= ========= A-33 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, 1998 1997 ---- ---- (in millions) Current: Accounts receivable $ 1.7 $ 1.6 Inventories 0.1 0.1 ------------------------------- Net deferred tax assets 1.8 1.7 ------------------------------- Non-current: Foreign tax credit carryforwards 23.4 26.1 AMT credit carryforwards 12.2 11.5 Property, plant and equipment (58.5) (43.5) Other 1.8 (0.8) Valuation allowance for deferred tax assets (35.6) (37.6) ------------------------------- Net deferred tax liabilities (56.7) (44.3) ------------------------------- Total net deferred tax liabilities $(54.9) $(42.6) =============================== At December 31, 1998, the foreign tax credit carryforward available to reduce possible future U.S. income tax amounted to approximately $23.4 million all of which expires in 2000. In 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 is 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 has not recorded the benefit of foreign tax credit carryforwards because of both the expiration dates and the rules governing the order in which such credits are utilized. The Company also has not recorded a benefit for the AMT credits, which are not available to reduce AMT. Because of limitations on both percentage depletion and foreign tax credits under the AMT, the Company expects an AMT liability for the foreseeable future. Thus, while such credits do not expire, it is unlikely they will be utilized. Accordingly, a valuation allowance has been established for the full amount of the foreign tax credit carryforward and the AMT credit carryforward. The Company obtains income tax credits in Peru for value-added taxes 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. A-34 5. Net Sales Net sales by country were as follows: For the years ended December 31, 1998 1997 1996 ---- ---- ---- (in millions) United States $127.5 $132.1 $ 77.4 Italy 86.9 110.0 109.4 United Kingdom 96.1 98.4 110.3 The Netherlands 57.7 83.8 94.3 Japan 44.7 72.5 82.0 Foreign - Other 215.0 317.4 279.6 ------------- ----------- ------------ Net sales $627.9 $814.2 $753.0 ============= =========== ============ At December 31, 1998, the Company had recorded sales of 27.5 million pounds of copper at a provisional price of 66 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 in the first quarter of 1999. 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 Mitsui, at its option up to 26,455 tons of copper cathodes annually for a seven year period from 1994 through 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 uses 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. Earnings include pre-tax gains from option sales and exercises of $7.2 million in 1998, $10.2 million in 1997 and $9.9 million in 1996. At December 31, 1998, the Company held no copper put options. A-35 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 as a component of cost of sales. As of December 31, 1998 and 1997, the Company has entered into the following fuel swap agreements: Weighted Average Contract Quantity Price Fuel Type Period (Barrels) (per Barrel) - ----------------- --------------- --------------------- ---------------- 1998 Residual Oil 1/99-9/99 1,095,000 $ 9.84 Diesel Fuel 1/99-9/99 432,000 $15.80 1997 Residual Oil 1/98-12/98 540,000 $13.57 Diesel Fuel 1/98-12/98 200,000 $21.17 In the event of a hypothetical 10 percent decrease in the respective fuel prices, the Company would incur higher production costs in 1999 of approximately $3.2 million over the life of the contracts than it would have incurred had the exposure not been hedged. In 1998, the Company's production cost would have been $3.3 million lower if this exposure had not been hedged. The estimated fair value of the Company's financial instruments is: At December 31, 1998 1997 (in millions) Carrying Fair Carrying Fair Value Value Value Value ----- ----- ----- ----- Assets: Cash and cash equivalents $175.9 $175.9 $126.5 $126.5 Marketable securities - held to maturity 22.2 22.2 204.6 204.6 Put options - - 0.6 7.2 Fuel swap agreements - (1.6) - (0.5) Liabilities: Long-term debt $234.2 $225.0 $247.9 $248.3 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. Put options - Fair value is an estimate based on relevant market information such as: volatility of similar options, futures prices and the strike price. Fuel swap agreements - Fair value is based on quoted market prices. A-36 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 earnings and are included in "Cost of sales" on the earnings statement. The current portion of this participation which is accrued during the year is based on Branch taxable income and is 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. The Company acquired 1.0 million, 2.0 million and 1.8 million labor shares at a cost of $3.8 million, $8.9 million and $7.1 million in the years 1998, 1997 and 1996, respectively. The carrying value of the minority interest was reduced by $2.5 million, $5.1 million and $4.4 million in 1998, 1997 and 1996, respectively, and the excess paid over the carrying value 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 these acquisitions, the remaining labor shareholders hold a 1.9% interest in the Branch at December 31, 1998, 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. Inventories At December 31, 1998 1997 ---- ---- (in millions) Metals: Finished goods $ 1.5 $ 0.6 Work-in-process 37.9 45.0 Supplies, net of reserves 49.5 63.1 ----------------- ----------------- Total inventories $88.9 $108.7 ----------------- ----------------- 10.

A-37 11. Other Current Liabilities At December 31, 1998 1997 ---- ---- (in millions) Accrued workers' participation $ 1.2 $13.8 Accrued severance pay, current portion 1.8 1.7 Salaries and wages 7.8 8.0 Taxes on income 22.0 18.0 Other 2.0 - ----------------- ----------------- Total other current liabilities $34.8 $41.5 ----------------- ----------------- 12. Debt and Available Credit Facilities Long-term debt at December 31, 1998 1997 ---- ---- (in millions) 6.43% EXIM Bank credit agreement $ 14.6 $ 20.4 CAF credit agreement - 8.9% 19.6 27.5 7.9% Secured Export Notes (SENS) due 2007 150.0 150.0 8.25% Corporate bonds due 2004 50.0 50.0 --------------- ----------------- Total debt 234.2 247.9 Less, current portion 13.7 13.7 --------------- ----------------- Total long-term debt $220.5 $234.2 --------------- ----------------- Interest paid by the Company (excluding amounts capitalized of $10.6 million and $2.3 million in 1998 and 1997, respectively) was $12.5 million, $19.0 million and $10.8 million in 1998, 1997 and 1996, respectively. Fees paid for loan agreements of $13.9 million in 1997 are included in other assets and amortized over the respective terms of the loans. Aggregate maturities of the borrowings outstanding at December 31, 1998, are as follows (in millions): 1999 $ 13.7 2000 23.3 2001 24.3 2002 18.9 2003 20.5 Thereafter 133.5 -------------------- Total $234.2 -------------------- In 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, 1998. Also in 1997, the Company privately placed $150 million of SENS 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. A-38 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 $1,106 million at December 31, 1998. In accordance with the most restrictive covenant of the Company's loan agreements, additional indebtedness of $874.4 million would have been permitted at December 31, 1998. 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 SENS 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 SENS 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 collections 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, 1998. Included in Other assets are $11.2 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 a noncontributory, defined benefit pension plan 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 invested in commingled stock and bond funds. 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. A-39 The components of net periodic benefit costs are as follows: For the years ended December 31, 1998 1997 1996 ---- ---- ---- (in millions) Service cost $ 0.6 $ 0.4 $ 0.5 Interest cost 0.7 0.5 0.5 Expected return on plan assets (0.7) (0.5) (0.4) Amortization of prior service cost 0.1 - - Amortization of transitional obligation 0.2 0.2 0.2 ------------------------------------ Net periodic benefit cost $ 0.9 $ 0.6 $ 0.8 ------------------------------------ The change in benefit obligation and plan assets and a reconciliation of funded status are as follows: At December 31, 1998 1997 ---- ---- (in millions) Change in Benefit Obligation Projected benefit obligation at beginning of year $ 8.5 $ 5.9 Service cost 0.6 0.4 Interest cost 0.7 0.5 Plan amendments 1.1 2.6 Benefits paid (0.6) (0.4) Actuarial loss (gain) 0.8 (0.5) ----------------------------- Projected benefit obligation at end of year $ 11.1 $ 8.5 ============================= Change in Plan Assets Fair value of plan assets at beginning of year $ 7.7 $ 3.7 Actual return on plan assets 2.5 0.5 Plan amendment - 2.5 Employer contributions 1.5 1.4 Benefits paid (0.5) (0.4) ----------------------------- Fair value of plan assets at end of year $ 11.2 $ 7.7 ============================= Reconciliation of Funded Status Funded status $ 0.1 $ (0.8) Unrecognized actuarial gain (1.7) (0.6) Unrecognized transition obligation 1.6 1.8 Unrecognized prior service cost 1.0 - ----------------------------- Net amount reflected in consolidated Balance sheet $ 1.0 $ 0.4 ============================= Weighted Average Assumptions Discount rate 7.0% 7.0% Expected long-term rate of return on plan assets 8.0% 8.0% Rate of compensation increase 4.0% 4.0% A-40 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. The components of net periodic benefit costs are as follows: For the years ended December 31, 1998 1997 1996 ---- ---- ---- (in millions) Service cost $ 0.1 $ 0.1 $ 0.1 Interest cost 0.1 - - Amortization of prior service cost 0.1 0.1 0.1 Recognized actuarial loss - - - -------------------------------------- Net periodic benefit cost $ 0.3 $ 0.2 $ 0.2 ====================================== The change in benefit obligation and plan assets and a reconciliation of funded status are as follows: At December 31, 1998 1997 ---- ---- (in millions) Change in Benefit Obligation Benefit obligation at beginning of year $ 0.9 $ 0.9 Service cost 0.1 0.1 Interest cost 0.1 - Plan amendments 0.1 - Benefits paid - - Actuarial (gain) loss - (0.1) ------------------------------------ Benefit obligation at end of year $ 1.2 $ 0.9 ==================================== Reconciliation of Funded Status Funded status $(1.2) $(0.9) Unrecognized actuarial loss (0.1) (0.1) Unrecognized prior service cost 0.6 0.6 ----------------------------------- Postretirement benefit obligation $(0.7) $(0.4) ==================================== Weighted-Average Assumptions Discount rate 7% 7% Expected long-term rate of return on plan assets N/A N/A Rate of compensation increase 4% 4% A-41 The annual assumed rate of increase in the per capita cost of covered benefits (i.e., health care cost trend rate) is assumed to be 5% in 1999 and 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 would increase the accumulated postretirement benefit obligation costs for 1998 by $0.1 million and the service and interest cost components of net periodic postretirement benefit would have an insignificant change. Decreasing the assumed health care cost trend rates by one percentage point in each year would decrease the accumulated postretirement benefit obligation for 1998 by $0.1 million and the service and interest cost components of net periodic postretirement benefit costs would have an insignificant change. 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 1998 and 1997. A-42 14. Stockholders' Equity Common Stock: The stockholders of the Company at December 31, 1998 were: Percent of Total Number Shares of Shares -------------------- -------------------- Class A Common Shares: ASARCO Incorporated 43,348,949 54.3% Cerro Trading Company, Inc. 11,378,088 14.2 Phelps Dodge Overseas Capital Corporation 11,173,796 14.0 -------------------- -------------------- Total Class A 65,900,833 82.5 Common Shares 13,949,812 17.5 -------------------- -------------------- Total 79,850,645 100.0% -------------------- -------------------- Class A common shares are entitled to five votes per share. Common shares are entitled to one vote per share. 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, 1998, 737,610 shares are available for future grants under this plan (836,635 shares at December 31, 1997). The weighted average remaining contractual life of stock option's outstanding as of December 31, 1998 was 8.3 years. 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, 1998, 11,400 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 incentive 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 1998, 1997 and 1996, consistent A-43 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) 1998 1997 1996 ---- ---- ---- Net earnings - as reported $54.6 $185.7 $180.5 Net earnings - pro forma $54.4 $185.5 $180.4 Earnings per share (Basic) - as reported $0.68 $ 2.32 $ 2.25 Earnings per share (Diluted) - as reported $0.68 $ 2.32 $ 2.25 Earnings per share (Basic) - pro forma $0.68 $ 2.32 $ 2.25 Earnings per share (Diluted) - pro forma $0.68 $ 2.32 $ 2.25 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: 1998 1997 1996 ---- ---- ---- (in millions) Basic and diluted 79.9 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 1998: dividend yield of 4.8% (4.05%-1997, 6.57%-1996); expected volatility of 40.4% (29.2%-1997, 28.4%-1996); risk-free interest rate of 5.6% (6.31%-1997, 6.17%-1996); and expected life of 7.1 years (7.0 years-1997, 6.9 years-1996). Stock option activity over the past three 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 at January 1, 1998 158,785 16.20 16.06 to 17.06 Granted 99,025 12.78 12.78 Exercised - - - Canceled or expired (960) 16.16 16.06 to 16.25 ------------------ Outstanding and exercisable at December 31, 1998 256,850 $14.88 $12.78 to $17.06 15. Related Party Transactions Asarco, a 54.3% stockholder of the Company, provides legal, tax, treasury and administrative support services to the Company. The amounts paid to Asarco for these services were $1.0 million, $1.6 million and $0.8 million in 1998, 1997, and 1996, respectively. A-44 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 Company's products are exported from Peru to customers principally in Europe, Asia, South America and the United States. 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, 1998, the Company had invested 28.6% of its cash equivalents and marketable securities with Peruvian banks, of which 54.0% 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 58.3% of the trade accounts receivable at December 31, 1998, of which one customer represented 12.1%. 17. Commitments and Contingencies 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 $1.1 billion, budgeted to be spent through the year 2003. The Cuajone mine expansion which consists of an expansion in annual copper production by 130 million pounds at an estimated capital investment of $245 million was substantially completed at December 31, 1998, however, some new mining equipment will continue to be received over the next two years. The second stage of the program, the expansion and modernization of the Ilo smelter is expected to be completed over the period 1998-2003 at an estimated cost of $875 million. In 1998, the Company commenced a $48 million project to expand annual SX/EW copper production by 26 million pounds. Project completion is expected in the third quarter of 1999. As a result of the expansion program, electric power requirements will increase significantly, requiring the construction of substantial additional generating capacity. In 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 agreed to purchase its power needs for the next twenty years. A-45 Environmental: 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, approved in January 1997, 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 within a period of five years, except for environmental controls applicable to its smelter operation which must be put in place within ten 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. See "Management's Discussion and Analysis of Financial Condition and Results of Operations - Expansion and Modernization Project." Under current Peruvian law and regulations, compliance with the PAMA will satisfy environmental requirements pertaining to the Company's operations during the applicable five-or-ten year implementation period. The Company remains, however, subject to other environmental requirements applicable to its operations. Environmental capital expenditures were $25.3 million, $43.8 million and $24.6 million in 1998, 1997 and 1996, respectively. In addition, the Company estimates spending $75.9 million for environmental control capital expenditures in 1999. Litigation: In April 1996, 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 the Company. The Superior Court remanded the case for a new trial. Plaintiffs 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 the Company a similar lawsuit filed by 127 additional former employees. In the third quarter of 1997, the court of first instance dismissed their complaint. Upon appeal filed by the plaintiffs, the Superior Court of Lima, in the third quarter of 1998, nullified the lower court's decision on technical grounds and remanded the case to the lower court for further proceedings. 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.

These financial statements are the responsibility of the Company'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. PricewaterhouseCoopers LLP New York, New York January 22, 1999 A-48 Item 9.

Section 5. Payment of Benefits.

(b) At any time subsequent to the Benefit Commencement Date, an Eligible Employee who made an election pursuant to Section 7(a) and who has suffered a severe financial hardship which has resulted from events beyond the Eligible Employee's control ("Hardship Event"), may request a payment of all or a portion of the value of his Deferral Amount which is not yet payable. If such a request shall be approved by the Committee payment of all or a portion of the value of the Deferral Amount shall be made as soon as practicable to the Eligible Employee but only in an amount reasonably needed to satisfy such Hardship Event. Whether a Hardship Event has occurred shall be determined in accordance with Treasury Regulation Sections 1.457- 2(h)(4) and (5). B-21 (c) At any time subsequent to the Benefit Commencement Date, an Eligible Employee who made an election pursuant to Section 7(a) may elect the acceleration of payment of all or a portion of the Deferral Amount not yet payable subject to a 6% penalty. Payment of such amount, less such penalty (which shall be forfeited), shall be paid in cash in a single lump sum as soon as practicable after the requested payment date. (d) At any time subsequent to the Benefit Commencement Date, an Eligible Employee who has made an election pursuant to Section 7(a) may file an election to amend such prior election affecting any amount payable at least 12 months subsequent to such amendment, provided no such election may accelerate any payment to a date earlier than 12 months from the date of amendment. The amended form of payment may be a single sum payment of any amounts not yet due and payable or annual installments of any such amounts, or a combination thereof, provided no payments may be extended longer than the time specified in Section 7(a). Section 8. Investment of Deferral Amounts. (a) Any Deferral Amount shall be deemed invested in accordance with an election to be made by the Eligible Employee in such investment vehicles as are provided under rules established by the Committee. SPCC will attempt to follow the Eligible Employee's elections, but will not be required to do so. Regardless of whether the Eligible Employee's elections are followed, the Deferral Amount shall be credited with deemed earnings, gains, losses, expenses, and changes in the fair market value of such Deferral Amount as if SPCC had followed such investment designations. All elections and amendments to elections shall be in accordance with rules, if any, as shall be established by the Committee. (b) The election of a deemed investment option is the sole responsibility of each Eligible Employee. Neither SPCC, nor the Committee that administers the Plan, nor any trustee of any trust that may be established in connection with the Plan are authorized or permitted to advise (or shall have any liability with respect to) an Eligible Employee as to the election of any option or the manner in which his Deferral Amount shall be deemed to be invested. Section 9. Value of Benefits. The amount of the lump sum referred to in Section 5(a) shall be the present value of the Benefit amount determined under Section 4 (after taking into account, if applicable, any reductions as set forth in the Pension Plan to reflect the commencement of payments prior to age 65) by assuming that the Eligible Employee has elected a single life annuity under the Pension Plan and by using the following actuarial assumptions: (a) Discount Rate. The discount rate used in computing the present value of benefits payable under the Plan is the yield on 10-year treasury notes on the Eligible Employee's Benefit Commencement Date, or if a legal holiday, the first business day immediately following the Benefit Commencement Date. At any time during a thirteen month period ending with the Benefit Commencement Date, an Eligible Employee may designate an alternative date for fixing the interest rate (the Alternative Date) used to calculate the value of the lump sum distribution. The designation must be in writing, and the Alternative Date must be within 7 calendar days of the date the designation is received by the Company. The designation of the Alternative Date for fixing the interest rate, once made, may not be changed for any reason. Notwithstanding the foregoing, if an Eligible Employee designates an Alternative Date under this subsection in contemplation of commencing benefits under the Pension Plan, such designation will survive a subsequent postponement of the commencement of benefits under the Pension Plan by such Eligible Employee, except that, if the yield on 10-year treasury notes on the Benefit Commencement Date is higher than on the Alternative Date, the yield on the Benefit Commencement Date will be used. B-22 (b) Mortality Table. The Mortality Table used will be that contained in U.S. Internal Revenue Service Revenue Ruling 95-6 or any succeeding Revenue Ruling issued by the Internal Revenue Service for use in applying the provisions of Sections 415 and 417(e) of the Internal Revenue Code. Section 10. Employee's Rights Unsecured. The right of any Eligible Employee to receive benefits under the provisions of the Plan shall be contractual in nature only; however, the amounts of such benefits may be held in a trust, the assets of which shall be subject to the claims of the Company's general creditors in the event of bankruptcy or insolvency only. Any amounts paid from such trust shall reduce the amount of benefits owed by the Company. Section 11. Severability. The provisions of this Plan shall be severable, and if any one or more provisions shall be considered or held to be invalid or unenforceable, or shall result in a portion of the Plan being treated as a pension plan under Title I of ERISA, the remaining provisions shall continue to be valid and enforceable. Section 12. Participation in Other Plans. Nothing in this Plan will affect any right which an Eligible Employee may otherwise have to participate in any other retirement plan, or agreement, which the Company may have now or hereafter. Section 13. Discretion of Company and Board. Any decision made or action taken by the Company or by the Board arising out of or in connection with the construction, administration, interpretation, and effect of the Plan shall lie within the absolute discretion of the Company or the Board, as the case may be, and shall be final, conclusive and binding upon all persons. Section 14. Assignment. No right or interest of the Eligible Employee under this Plan shall be subject to voluntary or involuntary alienation, assignment or transfer of any kind. B-23 Section 15. Cost to be Borne by Subsidiary. If any payment under this Plan is to be made to an Eligible Employee on account of any employee's service for a subsidiary of the Company, the cost of such payment shall be borne in such proportions as the Company and such subsidiary shall determine. Section 16. Amendment. This Plan may at any time or from time to time be amended, modified, discontinued or terminated by the Board if, in its sole discretion, such a change is deemed necessary and desirable. Section 17. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York. IN WITNESS WHEREOF, the Company has caused this Amendment to its Supplemental Retirement Plan to be duly adopted and executed by its duly authorized officers and its corporate seal affixed hereto on the 30th day of April, 1998.

An election to participate must be received by the Company prior to January 1 of the calendar year during which the election is to be effective and shall be irrevocable for the entire year. Notwithstanding the foregoing, a Director may elect to become a Participant in the Plan for the calendar year in which he first becomes eligible by filing a written election to participate within 30 days of becoming eligible. The election will be effective on a prospective basis and only as to remuneration not yet earned. An election shall remain in effect for subsequent years unless amended or terminated in writing prior to January 1 of any subsequent year.

The Company will establish a Participant Account for each Participant. Each Participant Account will have an SPCC Stock Subaccount and/or an Investment Subaccount. A Participant must allocate his Deferral Amounts, in increments of 25 percent, to one or both of the Subaccounts. (a) Deferral Amounts Allocated to SPCC Stock Subaccounts 1) A Participant's SPCC Stock Subaccount shall be deemed invested in accordance with the Participant's election in whole shares of Company common stock which could be purchased at Fair Market Value with the Deferral Amounts credited to a Participant's SPCC Stock Subaccount on the last business day of each calendar quarter. 2) The Stock Subaccount also shall be credited with a bookkeeping entry indicating the number of additional whole shares which could be purchased at Fair Market Value with any dividends payable on the deemed shares held in the SPCC Stock Subaccount on the day such dividends are payable to shareholders of Company common stock. 3) Any amounts that are insufficient to permit the crediting of a whole share of Company common stock shall be carried as a cash balance bookkeeping entry in such Stock Subaccount. On any date on which new funds are available for deemed investment in Company stock (either due to an additional deferral or the availability of deemed dividends), the cash amount will be added to any such other funds, and the maximum number of whole shares that could be purchased at Fair Market Value will be deemed invested. The remaining amount, if any, will be held as cash. No interest shall be credited on any such Stock Subaccount cash balance. 4) The SPCC Stock Subaccount shall be adjusted to reflect any stock split, stock dividend, recapitalization, merger, consolidation, reorganization or other similar change in the Company's common stock. B-26 (b) Deferral Amounts Allocated to Investment Subaccounts A Participant's Deferral Amounts will be credited to his Investment Subaccount except to the extent he has elected in writing to credit his Deferral Amounts to his Stock Subaccount. Each Investment Subaccount will be credited with interest from the date on which deferred compensation would normally have been paid, until payment, at a rate equal to the yield rate for U.S. Treasury debt obligations with a 10-year maturity effective for the last business day in each quarter, on the first day of each calendar quarter in which such interest is credited to the Participant's Investment Subaccount. Interest will be compounded quarterly. Section 6. Transfers. No election may be made to have amounts previously credited to a Participant's Investment Subaccount transferred to his Stock Subaccount. Amounts previously credited to a Participant's Stock Subaccount may not be transferred to his Investment Subaccount, except on or after the earlier in time of (a) one year prior to Normal Retirement Date, or (b) the date of termination. Section 7. Payment of Deferred Compensation. (a) Retirement at Normal Retirement Date A Participant who retires at his Normal Retirement Date will receive the entire value of his Participant Account in cash on January 15 of the year following the year of retirement. (b) Termination at Other than Normal Retirement Date A Participant who terminates service as a Director at a date other than Normal Retirement Date will receive the entire value of his Participant Account in cash on the 15th day of the 13th month following the date of termination. (c) Further Deferral Notwithstanding (a) and (b) of this section, a Participant may elect to further defer receipt of all or a portion of his Participant Account for a period of up to 10 years from the earlier in time of the Deemed Retirement Date or the date of termination. In order to defer a payment of benefits under the Plan, a Participant must file a written election at least one year in advance of the date that a payment of benefits under the Plan would otherwise be made. The Participant may elect to receive the amount deferred in a single cash payment or in annual cash installments. Any further elections to defer the receipt of benefits under the Plan must also be filed at least one year prior to the scheduled payment date. Acceleration of any benefits deferred pursuant to this paragraph can only be made by filing a request for payment at least one year in advance of the requested accelerated payment date. B-27 (d) Financial Hardship of Participants At any time a Participant may request a payment of all or a portion of the value of his Participant Account. Such a request shall be approved by the Company only upon a finding that the Participant has suffered a severe financial hardship which has resulted from events beyond the Participant's control ("Hardship Event"), and only in the amount reasonably needed to satisfy such Hardship Event. Whether a Hardship Event has occurred shall be determined in accordance with Treasury Regulation Sections 1.457- 2(h)(4) and (5). In the event such a payment is approved, payment of all or a portion of the value of the Participant Account shall be made as soon as practicable to the Participant. (e) Other Withdrawals Absent a Hardship Event or adequate prior notice (in accordance with paragraph (c) above), a request for a payment of all or a portion of the value of a Participant Account may be made by a Participant subject to a 6% penalty of the amount of the requested payment, which penalty shall be deducted from the requested payment. The requested payment, less such penalty, shall be paid in cash in a single lump sum as soon as practicable after the requested payment date. Section 8. Designation of Beneficiary. (a) A Participant may designate a beneficiary by giving written notice to the Company. If no beneficiary is designated, the beneficiary will be the Participant's estate. If more than one beneficiary statement has been filed, the beneficiary or beneficiaries designated in the statement bearing the most recent date will be deemed the valid beneficiary. (b) In the event of a Participant's death before he has received all of the benefits to which he is entitled hereunder, the value of the Participant's Participant Account shall be paid to the estate or designated beneficiary of the deceased Participant in one cash lump sum as soon as practicable after the first January 15 or July 15 following such date of death, unless the Participant has elected to continue without change the schedule for payment of benefits, in which case the beneficiary shall have the right to transfer amounts previously credited to a Participant's Stock Subaccount to his Investment Subaccount. (c) If a distribution is to be made to a beneficiary and such beneficiary dies before such distribution has been made, the amount of the distribution will be paid to the estate of the beneficiary in one lump sum. Section 9. Participant's Rights Unsecured. The right of any Participant to receive benefits under the provisions of the Plan shall be contractual in nature only; however, the amounts of such benefits may be held in a trust, the assets of which shall be subject to the claims of the Company's general creditors only in the event of bankruptcy or insolvency. Any amounts paid to a Participant from such trust shall reduce the amount of benefits owed by the Company. B-28 Section 10. Assignability. No right to receive payments hereunder shall be transferable or assignable by a Participant or beneficiary. Section 11. Participation in Other Plans. Nothing in this Plan will affect any right which a Participant may otherwise have to participate in any other retirement plan or agreement which the Company may have now or hereafter. Section 12. Discretion of Company and Board.

Section 13. Amendment. This Plan may at any time or from time to time be amended, modified or terminated by the Board. No amendment, modification or termination shall, without the consent of a Participant, adversely affect such Participant's accruals in his Participant Account. Section 14. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York.

If a Participant terminates service with the Company prior to qualifying for normal Retirement, the value of his Participant Account will be distributed in cash on the 15th day of the 13th month following the date of termination (subject to Section 15). In the event of the death of a Participant before receiving the value of his Participant Account, such distribution shall be paid to his beneficiary or beneficiaries designated pursuant to Section 7 as soon as practicable under the Plan. b) Further Deferral Notwithstanding subsection (a) of this section, a Participant who retires from the Company, and who at the time of retirement has a balance in his Participant's Account of at least $50,000, may elect to further defer receipt of all or a portion of his Participant Account, but not less than $50,000 for a period of up to 20 years from his date of retirement from the Company. To defer a payment of benefits under the Plan, a Participant must file a written election at least one year in advance of the date that payment of benefits under the Plan would otherwise be made. The Participant may elect to receive the amount deferred in a single cash payment or in annual cash installments. Any further elections to defer the receipt of benefits under the Plan must also be filed at least one year prior to the scheduled payment date. Acceleration of any benefits deferred pursuant to this paragraph can be made by filing a request for payment at least one year in advance of the requested accelerated payment date. c) Financial Hardship of Participants Except as may otherwise be provided by the terms of a Special Incentive Award, at any time prior to commencement of payment of benefits pursuant to paragraph (b) of this Section 6, a Participant may request a payment of all or a portion of the value of his Participant Account. Such a request shall be approved by the Committee only upon a finding that the Participant has suffered a severe financial hardship which has resulted from events beyond the Participant's control ("Hardship Event"), and only in the amount reasonably needed to satisfy such Hardship Event. Whether a Hardship Event has occurred shall be determined in accordance with Treasury Regulation Sections 1.457- 2(h)(4) and (5). In the event such a payment is approved, payment of all or a portion of the value of the Participant Account shall be made as soon as practicable to the Participant. d) Other Withdrawals Absent a Hardship Event or adequate prior notice (in accordance with paragraph (b) above), a request for a payment of all or a portion of the value of a Participant Account may be made by a Participant subject to a 6% penalty of the amount of the requested payment, which penalty shall be deducted from the requested payment. The requested payment, less such penalty, shall be paid in cash in a single lump sum as soon as practicable after the requested payment date. Section 7 - Designation of Beneficiary. A Participant may designate one or more beneficiaries by giving written notice to the Committee. If no beneficiary is so designated, the Participant's beneficiary will be the Participant's estate. If more than one beneficiary statement has been filed the beneficiary or beneficiaries designated in the statement bearing the most recent date will be deemed the valid beneficiary. B-35 Section 8 - Participant's Rights Unsecured. The right of any Participant to receive benefits under the provisions of the Plan shall be contractual in nature only; however, the amounts of such benefits may be held in a trust, the assets of which shall be subject to the claims of the Company's general creditors only in the event of bankruptcy or insolvency. Any amounts paid to a Participant from such trust shall reduce the amount of benefits owed by the Company. Section 9 - Participation in Other Plans. Nothing in this Plan will affect any right which a Participant may otherwise have to participate in any other retirement plan or agreement which the Company may have now or hereafter. Section 10 - Non-Alienation of Benefits. No right to receive payments hereunder shall be transferable or assignable by a Participant or beneficiary. Section 11 - Administration of the Plan. The Plan shall be administered by the Committee. The Committee shall construe and interpret the Plan and may adopt rules and regulations governing the administration of the Plan, as well as exercise any duties and powers conferred on it by the terms of the Plan. The Committee shall act by vote or written consent of a majority of its members or otherwise as in accordance with its general procedures as in effect from time to time. Section 12 - Amendment or Termination of the Plan. This Plan may at any time or from time to time be amended, modified or terminated by the Board. No amendment, modification or termination shall, without the consent of a Participant, adversely affect such Participant's accruals in his Participant Account. Section 13 - No Entitlement to Awards or Right of Continued Employment. Neither the establishment of the Plan nor the payment of any benefits hereunder nor any action of the Company, a subsidiary of the Company, or the Committee shall be held or construed to confer upon any person any legal right to be awarded any amounts under the Incentive Plan or the Incentive Compensation Plan or to continue in the employ of the Company or a subsidiary of the Company. The Company and its subsidiaries expressly reserve the right to discharge any Participant whenever the interest of any such company in its sole discretion may so require without liability to such company or the Committee except as to any rights which may be expressly conferred upon such Participant under the Plan. Section 14 - Discretion of Company, Committee, and Board. Any decision made or action taken by the Company or by the Committee or by the Board arising out of or in connection with the construction, administration, interpretation and effect of the Plan shall lie within the absolute discretion of the Company, the Committee or the Board, as the case may be, and shall be final, conclusive and binding upon all persons. B-36 Section 15 - Tax Withholding. There shall be deducted from all deferrals or payments made under this Plan the amount of any taxes required to be withheld by any Federal, state, local or foreign government, including any employment taxes required to be withheld under Code Section 3121(v). The Participants and their beneficiaries, distributees, and personal representatives will bear any and all Federal, foreign, state, local or other income or other taxes imposed on amounts paid under the Plan, and the Company may take whatever actions are necessary and proper to satisfy all obligations of such persons for payment of all such taxes. Section 17 - Severability. In the event any provision of this Plan would serve to invalidate the Plan, that provision shall be deemed to be null and void, and the Plan shall be construed as if it did not contain the particular provision that would make it invalid. Section 18 - Governing Law; Binding Effect; Miscellaneous. The Plan shall be governed and construed and enforceable in accordance with the laws of the State of New York, except as superseded by applicable Federal law. Where appearing in the Plan, the masculine gender shall include the feminine gender.
