BUSINESS The Company The Company was incorporated in 1920 under the laws of Arizona and is engaged principally in serving electricity in the State of Arizona. The principal executive offices of the Company are located at 400 North Fifth Street, Phoenix, Arizona 85004 (telephone 602-250-1000). Pinnacle West owns all of the outstanding shares of the Company's common stock. The Company is Arizona's largest electric utility, with 767,000 customers, and provides wholesale or retail electric service to the entire state of Arizona with the exception of Tucson and about one-half of the Phoenix area. During 1997, no single purchaser or user of energy accounted for more than 2% of total electric revenues. At December 31, 1997, the Company employed 5,981 people, which includes employees assigned to joint projects where the Company is project manager. This document contains forward-looking statements that involve risks and uncertainties. Words such as "estimates," "expects," "anticipates," "plans," "believes," "projects," and similar expressions identify forward-looking statements. These risks and uncertainties include, but are not limited to, the ongoing restructuring of the electric industry; the outcome of the regulatory proceedings relating to the restructuring; regulatory, tax and environmental legislation; the ability of the Company to successfully compete outside its traditional regulated markets; regional economic conditions, which could affect customer growth; the cost of debt and equity capital; weather variations affecting customer usage; and technological developments in the electric industry. See "Competition" in this Item for a discussion of some of these factors. Competition Retail General. Under current law, the Company is not in direct competition with any other regulated electric utility for electric service in the Company's retail service territory. Nevertheless, the Company is subject to varying degrees of competition in certain territories adjacent to or within areas that it serves that are also currently served by other utilities in its region (such as Tucson Electric Power Company, Southwest Gas Corporation, and Citizens Utility Company) as well as cooperatives, municipalities, electrical districts and similar types of governmental organizations (principally SRP). The Company faces competitive challenges from low-cost hydroelectric power and natural gas fuel, as well as the access of some utilities to preferential low-priced federal power and other subsidies. In addition, some customers, particularly industrial and large commercial, may own and operate facilities to generate their own electric energy requirements. Such facilities may be operated by the customers themselves or by other entities engaged for such purpose. The legislatures and/or the regulatory commissions in most states have considered or are considering "retail wheeling." This requirement to transmit directly to retail customers could have the result of allowing retail customers to choose to purchase electric capacity and energy from the electric utility in whose service area they are located or from other electric utilities or independent power producers or power marketers. ACC Rules Regarding Arizona Electric Industry Restructuring. The ACC Staff has been conducting an ongoing investigation into the restructuring of the Arizona electric industry. In December 1996, the ACC adopted rules that provide a framework for the introduction of retail electric competition in Arizona in phases from 1999 to 2003. The ACC ordered in the rules that numerous issues require additional consideration prior to the implementation of retail electric competition in Arizona. During 1997, the ACC held workshops to gather input from various constituencies with respect to those issues. 3 The rules indicate that the ACC will allow recovery of unmitigated stranded costs, but do not set forth the mechanisms for determining and recovering such costs. In February 1998, the ACC completed a formal, generic hearing on stranded cost determination and recovery. Based on various assumptions, estimates and methodologies, the Company currently estimates that its stranded costs to be recovered (excluding regulatory assets which have already been addressed by the ACC) will be less than $500 million. The Company is seeking full recovery of stranded costs during a transition period proposed to go through 2006. Decisions by the ACC have not yet been made with respect to this issue. An Arizona joint legislative committee studied electric utility industry restructuring issues in 1996 and 1997. In conjunction with that study, Arizona legislative counsel prepared memoranda in late 1997 related to the legal authority of the ACC to deregulate the Arizona electric utility industry. The memoranda raise a question as to the degree to which the ACC may, under the Arizona Constitution, deregulate any portion of the electric utility industry and allow rates to be determined by market forces. In February 1998, a bill was introduced in the Arizona legislature to facilitate implementation of retail electric competition in the state. The bill has progressed through several stages to date. The bill includes, among other things, a proposal that the ACC adopt provisions for public service corporations substantially consistent with some of the bill's provisions for certain government-operated electric utilities. The Company continues to believe that legislation and perhaps amendments to the Arizona Constitution will ultimately be required before significant implementation of retail electric competition can lawfully occur in Arizona. See Note 3 of Notes to Financial Statements for additional information regarding the rules and other regulatory and legal issues relating to the electric industry restructuring. Wholesale General. The Company competes with other utilities, power marketers, and independent power producers in the sale of electric capacity and energy in the wholesale market. The Company expects that competition to sell capacity will remain vigorous, and that wholesale prices will remain depressed for at least the next several years due to increased competition and surplus capacity in the western United States. The Company's rates for wholesale power sales and transmission services are subject to regulation by the FERC. During 1997, approximately 13% of the Company's electric operating revenues resulted from such sales and charges. The National Energy Policy Act of 1992 (the "Energy Act") has promoted increased competition in the wholesale electric power markets. The Energy Act reformed provisions of the Public Utility Holding Company Act of 1935 (the "1935 Act") and the Federal Power Act to remove certain barriers to competition for the supply of electricity. For example, the Energy Act permits the FERC to order transmission access for third parties to transmission facilities owned by another entity so that independent suppliers and other third parties can sell at wholesale to customers wherever located. The Energy Act does not, however, permit the FERC to issue an order requiring transmission access to retail customers. Effective July 9, 1996, a FERC decision requires all electric utilities subject to the FERC's jurisdiction to file transmission tariffs which provide competitors with access to transmission facilities comparable to the transmission owners' access for wholesale transactions, establishes information requirements and provides for recovery of certain wholesale stranded costs. Retail stranded costs resulting from a state-authorized retail direct-access program are the responsibility of the states, unless a state lacks authority to impose rates to recover such costs, in which case FERC will consider doing so. The Company has filed its revised open access tariff in accordance with this decision. The Company does not believe that this decision will have a material adverse impact on its results of operations or financial position. 4 Federal Regulation Several electric utility reform bills have been introduced during recent Congressional sessions, which as currently written, would allow consumers to choose their electric supplier by 2000 or 2003. These bills, other bills that are expected to be introduced, and ongoing discussions at the federal level suggest a wide range of opinion that will need to be narrowed before any substantial restructuring of the electric utility industry can occur. Regulatory Assets The Company's major regulatory assets are deferred income taxes and rate synchronization cost deferrals. These items, combined with miscellaneous regulatory assets and liabilities, amounted to approximately $1.0 billion at December 31, 1997. In accordance with a 1996 regulatory agreement, the ACC accelerated the amortization of substantially all of the Company's regulatory assets to an eight-year period beginning July 1, 1996. The Company's existing regulatory orders and current regulatory environment support its accounting practices related to regulatory assets. If rate recovery of these assets is no longer probable, whether due to competition or regulatory action, the Company would no longer be able to apply the provisions of SFAS No. 71 to all or some part of its operations which could have a material impact on the Company's financial statements. See Notes 1, 3 and 10 of Notes to Financial Statements in Item 8 for additional information. Competitive Strategies The Company is pursuing strategies to maintain and enhance its competitive position. These strategies include (i) cost management, with an emphasis on the reduction of variable costs (fuel, operations, and maintenance expenses) and on increased productivity through technological efficiencies; (ii) a focus on the Company's core business through customer service, distribution system reliability, business segmentation and the anticipation of market opportunities; (iii) an emphasis on good regulatory relationships; (iv) asset maximization (e.g., higher capacity factors and lower forced outage rates); (v) strengthening the Company's capital structure and financial condition; (vi) leveraging core competencies into related areas, such as energy management products and services; and (vii) establishing a trading floor and implementing a risk management program to provide for more stability of prices and the ability to retain or grow incremental margin through more competitive pricing and risk management. Underpinning the Company's competitive strategies are the strong growth characteristics of the Company's service territory. As competition in the electric utility industry continues to evolve, the Company will continue to evaluate strategies and alternatives that will position the Company to compete effectively in a more competitive, restructured industry. Generating Fuel and Purchased Power 1997 Energy Mix The Company's sources of energy during 1997 were: coal - 36.5%; nuclear - 28.2%; other - 3.1%; and purchased power - 32.2%. Coal Supply The Company believes that Cholla has sufficient reserves of low sulfur coal committed to the plant for the next two years, the term of the existing coal contract. In 1997, the current supplier experienced production and delivery problems that required Cholla to purchase coal from the spot market. The current supplier is expected to continue to provide substantially all of Cholla's low sulfur coal requirements. Contract renegotiation with the current supplier is in progress. The current supplier has sufficient reserves of low sulfur coal available to allow the continued operation of Cholla for its useful life. The Company also believes that Four Corners and NGS have sufficient reserves of low sulfur coal available for use by those plants to continue operating them for their useful lives. 5 The current sulfur content of coal being used at Four Corners, NGS and Cholla is approximately 0.78%, 0.55% and 0.44%, respectively. In 1997, average prices paid for coal supplied from the reserves dedicated under the existing contracts were comparable to 1996. Escalation components of existing long-term coal contracts impact future coal prices. In addition, major price adjustments can occur from time to time as a result of contract renegotiation. NGS and Four Corners are located on the Navajo Reservation and held under easements granted by the federal government as well as leases from the Navajo Nation. See "Properties- Plant Sites Leased from the Navajo Nation" in Item 2. The Company purchases all of the coal which fuels Four Corners from a coal supplier with a long-term lease of coal reserves owned by the Navajo Nation and for NGS from a coal supplier with a long-term lease with the Navajo Nation and the Hopi Tribe. Coal is supplied to Cholla from a coal supplier who mines all of the coal under a long-term lease of coal reserves owned by the Navajo Nation, the federal government, and private landholders. See Note 12 of Notes to Financial Statements in Item 8 for information regarding the Company's obligation for coal mine reclamation. Natural Gas Supply The Company is a party to contracts with a number of natural gas operators and marketers which allow the Company to purchase natural gas in the method it determines to be most economic. The Company is currently purchasing the majority of its natural gas requirements from twelve companies pursuant to contracts. The Company's natural gas supply is transported pursuant to a firm transportation service contract between the Company and El Paso Natural Gas Company. The Company continues to analyze the market to determine the source and method of meeting its natural gas requirements. Nuclear Fuel Supply The fuel cycle for Palo Verde is comprised of the following stages: (1) the mining and milling of uranium ore to produce uranium concentrates, (2) the conversion of uranium concentrates to uranium hexafluoride, (3) the enrichment of uranium hexafluoride, (4) the fabrication of fuel assemblies, (5) the utilization of fuel assemblies in reactors and (6) the storage of spent fuel and the disposal thereof. The Palo Verde participants have made arrangements through contract flexibilities to obtain quantities of uranium concentrates anticipated to be sufficient to meet operational requirements through 2000. Existing contracts and options could be utilized to meet approximately 80% of requirements in 2001 and 2002 and 50% of requirements from 2003 through 2007. Spot purchases in the uranium market will be made, as appropriate, in lieu of any uranium that might be obtained through contract flexibilities and options. The Palo Verde participants have contracted for all conversion services required through 1998 and for up to 60% through 2002. The Palo Verde participants, including the Company, have an enrichment services contract with USEC which obligates USEC to furnish enrichment services required for the operation of the three Palo Verde units over a term expiring in September 2002, with options to continue through September 2007. In addition, existing contracts will provide fuel assembly fabrication services until at least 2003 for each Palo Verde unit, and through contract options, approximately fifteen additional years are available. Spent Nuclear Fuel and Waste Disposal. Pursuant to the Nuclear Waste Policy Act of 1982, as amended in 1987 (the "Waste Act"), DOE is obligated to accept and dispose of all spent nuclear fuel and other high-level radioactive wastes generated by all domestic power reactors. The NRC, pursuant to the Waste Act, requires operators of nuclear power reactors to enter into spent fuel disposal contracts with DOE, and the Company, on its own behalf and on behalf of the other Palo Verde participants, has done so. Under the Waste Act, DOE was to develop the facilities necessary for the storage and disposal of spent nuclear fuel and to have the first such facility in operation by 1998. That facility was to be a permanent repository, but DOE has announced that such a repository now cannot be completed before 2010. In July 1996, the United States Court of Appeals for the District of Columbia Circuit (D.C. Circuit) ruled that the DOE has an obligation to start disposing of spent nuclear fuel no 6 later than January 31, 1998. By way of letter dated December 17, 1996, DOE informed contract holders, including the Company, that DOE anticipates that it will be unable to begin acceptance of spent nuclear fuel for disposal in a repository or interim storage facility by January 31, 1998. In November 1997, the D.C. Circuit issued a Writ of Mandamus precluding DOE from excusing its own delay on the grounds that DOE has not yet prepared a permanent repository or interim storage facility. Several bills have been introduced in Congress contemplating the construction of a central interim storage facility which could be available in the latter part of the current decade; however, there is resistance to certain features of these bills both in Congress and the Administration. Facility funding is a further complication. While all nuclear utilities pay into a so-called nuclear waste fund an amount calculated on the basis of the output of their respective plants, the annual Congressional appropriations for the permanent repository have been for amounts less than the amounts paid into the waste fund (the balance of which is being used for other purposes) and, according to DOE spokespersons, may now be at a level less than needed to achieve a 2010 operational date for a permanent repository. No funding will be available for a central interim facility until one is authorized by Congress. The Company has storage capacity in existing fuel storage pools at Palo Verde which, with certain modifications, could accommodate all fuel expected to be discharged from normal operation of Palo Verde through about 2002, and believes it could augment that wet storage with new facilities for on-site dry storage of spent fuel for an indeterminate period of operation beyond 2002, subject to obtaining any required governmental approvals. One way or another, the Company currently believes that spent fuel storage or disposal methods will be available for use by Palo Verde to allow its continued operation beyond 2002. A new low-level waste facility was built in 1995 on-site which could store an amount of waste equivalent to ten years of normal operation at Palo Verde. Although some low-level waste has been stored on-site, the Company is currently shipping low-level waste to off-site facilities. The Company currently believes that interim low-level waste storage methods are or will be available for use by Palo Verde to allow its continued operation and to safely store low-level waste until a permanent disposal facility is available. While believing that scientific and financial aspects of the issues of spent fuel and low-level waste storage and disposal can be resolved satisfactorily, the Company acknowledges that their ultimate resolution in a timely fashion will require political resolve and action on national and regional scales which it is less able to predict. Purchased Power Agreements In addition to that available from its own generating capacity (see "Properties" in Item 2), the Company purchases electricity from other utilities under various arrangements. One of the most important of these is a long-term contract with SRP which may be canceled by SRP on three years' notice and which requires SRP to make available, and the Company to pay for, certain amounts of electricity that are based in large part on customer demand within certain areas now served by the Company pursuant to a related territorial agreement. The generating capacity available to the Company pursuant to the contract was 297 MW through May 1997, at which time the capacity decreased to 292 MW. In 1997, the Company received approximately 610,400 MWh of energy under the contract and paid approximately $37 million for capacity availability and energy received. In September 1990, the Company and PacifiCorp entered into certain agreements relating principally to sales and purchases of electric power and electric utility assets, and in July 1991 the Company sold Cholla 4 to PacifiCorp. As part of the transaction, PacifiCorp agreed to make a firm system sale to the Company for thirty years during the Company's summer peak season in the amount of 175 megawatts for the first five years, increasing thereafter, at the Company's option, up to a maximum amount equal to the rated capacity of Cholla 4 (380 megawatts). The Company also had the option to convert these firm system sales to one-for-one seasonal capacity exchanges with PacifiCorp. The Company's agreements with PacifiCorp currently provide for the following Company purchases and one-for-one seasonal capacity exchanges during the indicated years: 1998 (175 megawatt firm capacity purchase, converting to capacity exchange in the summer of 1998; and 100 megawatt 7 capacity exchange); 1999 and beyond (275 megawatt capacity exchange; and 205 megawatt capacity exchange beginning in the summer of 1999). In 1997, the generating capacity available to the Company from PacifiCorp was 175 MW. The Company received approximately 486,000 MWh of energy and paid approximately $17.4 million for capacity availability and the energy received. During 1996, the Company entered into an agreement with Citizens Utilities Company to build, own, operate and maintain a combustion turbine in northwest Arizona. Pursuant to a twenty-year purchase power agreement, the Company will recover the cost of the turbine and CUC will pay for the output requested by CUC. The Company has the right to secondary use of the output for cost of fuel and variable operations and maintenance. The Company expects that the combustion turbine will be in service during the first quarter of 2001. Construction Program During the years 1995 through 1997, the Company incurred approximately $824 million in capitalized expenditures. Utility capitalized expenditures for the years 1998 through 2000 are expected to be primarily for expanding transmission and distribution capabilities to meet customer growth, upgrading existing facilities, and for environmental purposes. Capitalized expenditures, including expenditures for environmental control facilities, for the years 1998 through 2000 have been estimated as follows: (Millions of Dollars) By Year By Major Facilities - -------------------------------- ---------------------------------------- 1998 $323 Production $235 1999 313 Transmission and Distribution 565 2000 306 General 119 ---- Other Projects 23 $942 ---- ==== $942 ==== The amounts for 1998 through 2000 exclude capitalized interest costs and include capitalized property taxes and about $30- $35 million each year for nuclear fuel. The Company conducts a continuing review of its construction program. Mortgage Replacement Fund Requirements So long as any of the Company's first mortgage bonds are outstanding, the Company is required for each calendar year to deposit with the trustee under its Mortgage cash in a formularized amount related to net additions to the Company's mortgaged utility plant; however, the Company may satisfy all or any part of this "replacement fund" requirement by utilizing redeemed or retired bonds, net property additions, or property retirements. For 1997, the replacement fund requirement amounted to approximately $134 million. All of the bonds issued by the Company under the Mortgage which are callable prior to maturity are redeemable at their par value plus accrued interest with cash deposited by the Company in the replacement fund, subject in many cases to a period of time after the original issuance of the bonds during which they may not be so redeemed and/or to other restrictions on any such redemption. Environmental Matters EPA Environmental Regulation Clean Air Act. Pursuant to the 1977 amendments to the Clean Air Act, the EPA adopted regulations that address visibility impairment in certain federally-protected areas which can be reasonably attributed to specific sources. In September 1991, the EPA issued a final rule that would limit sulfur dioxide emissions at NGS. Compliance with the emission limitation became applicable to one NGS unit in 1997 and becomes applicable to another unit in 1998 and to the last unit in 1999. SRP, the NGS operating agent, has estimated a capital cost of 8 $440 million and annual operations and maintenance costs of approximately $14 million for all three units, for NGS to meet these requirements. The Company is required to fund 14% of these expenditures. Approximately 80% of these capital costs have been incurred through 1997. The Clean Air Act Amendments of 1990 (the "Amendments") address, among other things, "acid rain," visibility in certain specified areas, toxic air pollutants and the nonattainment of national ambient air quality standards. With respect to "acid rain," the Amendments establish a system of sulfur dioxide emissions "allowances." Each existing utility unit is granted a certain number of "allowances." For Phase II plants, which includes Company-owned plants, allowances will be required beginning in the year 2000 to operate the plants. On March 5, 1993, the EPA promulgated rules listing allowance allocations applicable to Company-owned plants. Based on those allocations, the Company will have sufficient allowances to permit continued operation of its plants at current levels without installing additional equipment. In addition, the Amendments require the EPA to set nitrogen oxides emissions limitations which would require certain plants to install additional pollution control equipment. In December 1996, the EPA issued rules for nitrogen oxides emissions limitations that may require the Company to install additional pollution control equipment at Four Corners by January 1, 2000. Based on its initial evaluation, the Company currently estimates its capital cost of complying with the rules may be approximately $4 million. On February 14, 1997, the Company filed a Petition for Review in the United States Court of Appeals for the District of Columbia alleging that the EPA improperly classified Four Corners Unit 4 in these rules, thereby subjecting Unit 4 to a more stringent emission limitation. Arizona Public Service Company v. United States Environmental Protection Agency, No. 97-1091. In February 1998, the Court vacated the Unit 4 emission limitation and remanded the issue to EPA for reconsideration. The Company cannot currently predict how the EPA will respond. With respect to protection of visibility in certain specified areas, the Amendments require the EPA to conduct a study concerning visibility impairment in those areas and identification of sources contributing to such impairment. Interim findings of this study have indicated that any beneficial effect on visibility as a result of the Amendments would be offset by expected population and industry growth. The EPA has established a "Grand Canyon Visibility Transport Commission" to complete a study on visibility impairment in the "Golden Circle of National Parks" in the Colorado Plateau. NGS, Cholla and Four Corners are located near the "Golden Circle of National Parks." The Commission completed its study and on June 10, 1996 submitted its final recommendations to the EPA. The Commission recommended that, beginning in 2000 and every 5 years thereafter, if actual sulfur dioxide emissions from all stationary sources in an eight-state region (including Arizona, New Mexico, Utah, Nevada and California) exceed the projected emissions, which are projected to decline under the current regulatory scheme, the projected total emissions will be changed to a "regional emissions cap" and an emissions trading program would be implemented to limit total sulfur dioxide emissions in the region. The EPA will consider these recommendations before promulgating final requirements on a regional haze regulatory program which is under EPA review, which is expected by June 1998. If such a program were implemented, industry, including the Company's coal plants, could be subject to further emissions limits. The Company cannot currently estimate the capital expenditures, if any, which may be required as a result of the EPA studies and the Commission's recommendations. In July 1997, the EPA proposed regulations on regional haze. The proposal would require states to submit plans to meet "presumptive reasonable progress targets" for achieving perceptible improvements in visibility conditions in Federal Class I areas (e.g., national parks) every 10-15 years. The proposal also calls for states to conduct three year "best available retrofit technology" ("BART") review on point sources which became operational between 1962 and 1977 and which may normally be anticipated to contribute to regional haze visibility impairment. EPA is currently reviewing public comments and final regulations are expected to be promulgated by June 1998. Because the actual level of emissions controls, if any, for any unit cannot be determined at this time, the Company currently cannot estimate the capital expenditures, if any, which would result from the final rules. With respect to hazardous air pollutants emitted by electric utility steam generating units, the Amendments require two studies. The results of the first study indicated an impact from mercury emissions from such units in 9 certain unspecified areas; however, the EPA has not yet stated whether or not emissions limitations will be imposed. Next, the EPA will complete a general study by 1999 concerning the necessity of regulating such units under the Amendments. Due to the lack of historical data, and because the Company cannot speculate as to the ultimate requirements by the EPA, the Company cannot currently estimate the capital expenditures, if any, which may be required as a result of these studies. Certain aspects of the Amendments may require related expenditures by the Company, such as permit fees, none of which the Company expects to have a material impact on its financial position or results of operations. Also, in July 1997, EPA promulgated final National Ambient Air Quality Standards for ozone and particulate matter. Pursuant to the rules, the ozone standard is more stringent and a new ambient standard for very fine particles has been established. The Company does not currently expect these rules to have a material adverse effect on its financial position or results of operations. Superfund. The Comprehensive Environmental Response, Compensation, and Liability Act ("Superfund") establishes liability for the cleanup of hazardous substances found contaminating the soil, water or air. Those who generated, transported or disposed of hazardous substances at a contaminated site are among those who are potentially responsible parties ("PRP's") and may be each strictly, and often jointly and severally, liable for the cost of any necessary remediation of the substances. The EPA had previously advised the Company that the EPA considers the Company to be a PRP in the Indian Bend Wash Superfund Site, South Area, where the Company's Ocotillo Power Plant is located. The Company is in the process of conducting a voluntary investigation to determine the extent and scope of contamination at the plant site. Based on the information to date, the Company does not expect this matter to have a material impact on its financial position or results of operations. MGP Sites. The Company currently is investigating properties, either presently or previously owned by the Company, which were at one time sites of, or sites associated with, manufactured gas plants. The purpose of this investigation is to determine if waste materials are present, if such materials constitute an environmental or health risk, and if the Company has any responsibility for remedial action. Where appropriate, the Company has begun remediation of certain of these sites. The Company does not expect these matters to have a material adverse effect on its financial position or results of operations. Purported Navajo Environmental Regulation Four Corners and NGS are located on the Navajo Reservation and are held under easements granted by the federal government as well as leases from the Navajo Nation. The Company is the Four Corners operating agent and owns a 100% interest in Four Corners Units 1, 2 and 3, and a 15% interest in Four Corners Units 4 and 5. The Company owns a 14% interest in NGS Units 1, 2 and 3. In July 1995, the Navajo Nation enacted the Navajo Nation Air Pollution Prevention and Control Act, the Navajo Nation Safe Drinking Water Act, and the Navajo Nation Pesticide Act (collectively, the "Acts"). Pursuant to the Acts, the Navajo Nation Environmental Protection Agency is authorized to promulgate regulations covering air quality, drinking water and pesticide activities, including those that occur at Four Corners and NGS. By separate letters dated October 12 and October 13, 1995, the Four Corners participants and the NGS participants requested the United States Secretary of the Interior to resolve their dispute with the Navajo Nation regarding whether or not the Acts apply to operations of Four Corners and NGS. On October 17, 1995, the Four Corners participants and the NGS participants each filed a lawsuit in the District Court of the Navajo Nation, Window Rock District, seeking, among other things, a declaratory judgment that (i) their respective leases and federal easements preclude the application of the Acts to the operations of Four Corners and NGS, and (ii) the Navajo Nation and its agencies and courts lack adjudicatory jurisdiction to determine the enforceability of the Acts as applied to Four Corners and NGS. On October 18, 1995, the Navajo Nation and the Four Corners and NGS participants agreed to indefinitely stay the proceedings referenced in the preceding two sentences so that the parties may attempt to resolve the dispute without litigation, and the Secretary and the Court have stayed these 10 proceedings pursuant to a request by the parties. The Company cannot currently predict the outcome of this matter. In February 1998, the EPA promulgated regulations specifying those provisions of the Clean Air Act for which it is appropriate to treat Indian tribes in the same manner as states. The EPA indicated that it believes that the Clean Air Act generally would supersede pre-existing binding agreements that may limit the scope of tribal authority over reservations. The Company is reviewing the regulations to determine what effect they might have on the application of the Navajo Nation Air Pollution Prevention and Control Act on Four Corners and NGS. Water Supply Assured supplies of water are important both to the Company (for its generating plants) and to its customers and, at the present time, the Company has adequate water to meet its needs. However, conflicting claims to limited amounts of water in the southwestern United States have resulted in numerous court actions in recent years. Both groundwater and surface water in areas important to the Company's operations have been the subject of inquiries, claims and legal proceedings which will require a number of years to resolve. The Company is one of a number of parties in a proceeding before a state court in New Mexico to adjudicate rights to a stream system from which water for Four Corners is derived. (State of New Mexico, in the relation of S.E. Reynolds, State Engineer vs. United States of America, City of Farmington, Utah International, Inc., et al., San Juan County, New Mexico, District Court No. 75-184). An agreement reached with the Navajo Nation in 1985, however, provides that if Four Corners loses a portion of its rights in the adjudication, the Navajo Nation will provide, for a then-agreed upon cost, sufficient water from its allocation to offset the loss. A summons served on the Company in early 1986 required all water claimants in the Lower Gila River Watershed in Arizona to assert any claims to water on or before January 20, 1987, in an action pending in Maricopa County Superior Court. (In re The General Adjudication of All Rights to Use Water in the Gila River System and Source, Supreme Court Nos. WC-79-0001 through WC 79-0004 (Consolidated) [WC-1, WC-2, WC-3 and WC-4 (Consolidated)], Maricopa County Nos. W-1, W-2, W-3 and W-4 (Consolidated)). Palo Verde is located within the geographic area subject to the summons, and the rights of the Palo Verde participants, including the Company, to the use of groundwater and effluent at Palo Verde is potentially at issue in this action. The Company, as project manager of Palo Verde, filed claims that dispute the court's jurisdiction over the Palo Verde participants' groundwater rights and their contractual rights to effluent relating to Palo Verde and, alternatively, seek confirmation of such rights. Three of the Company's less-utilized power plants are also located within the geographic area subject to the summons. The Company's claims dispute the court's jurisdiction over the Company's groundwater rights with respect to these plants and, alternatively, seek confirmation of such rights. On December 10, 1992, the Arizona Supreme Court heard oral argument on certain issues in this matter which are pending on interlocutory appeal. Issues important to the Company's claims were remanded to the trial court for further action and the trial court certified its decision for interlocutory appeal to the Arizona Supreme Court. On September 28, 1994, the Arizona Supreme Court granted review of the trial court decision. No trial date concerning the water rights claims of the Company has been set in this matter. The Company has also filed claims to water in the Little Colorado River Watershed in Arizona in an action pending in the Apache County Superior Court. (In re The General Adjudication of All Rights to Use Water in the Little Colorado River System and Source, Supreme Court No. WC-79-0006 WC-6, Apache County No. 6417). The Company's groundwater resource utilized at Cholla is within the geographic area subject to the adjudication and is therefore potentially at issue in the case. The Company's claims dispute the court's jurisdiction over the Company's groundwater rights and, alternatively, seek confirmation of such rights. The parties are in the process of settlement negotiations with respect to this matter. No trial date concerning the water rights claims of the Company has been set in this matter. Although the foregoing matters remain subject to further evaluation, the Company expects that the described litigation will not have a material adverse impact on its financial position or results of operations. 11 ITEM 2. PROPERTIES Accredited Capacity The Company's present generating facilities have an accredited capacity aggregating 3,986,900 kW, comprised as follows: Capacity(kW) ------------ Coal: Units 1, 2 and 3 at Four Corners, aggregating...................................... 560,000 15% owned Units 4 and 5 at Four Corners, representing.............................. 222,000 Units 1, 2 and 3 at Cholla Plant, aggregating...................................... 615,000 14% owned Units 1, 2 and 3 at the Navajo Plant, representing....................... 315,000 --------- 1,712,000 ========= Gas or Oil: Two steam units at Ocotillo and two steam units at Saguaro, aggregating............ 435,000(1) Eleven combustion turbine units, aggregating....................................... 493,000 Three combined cycle units, aggregating............................................ 255,000 --------- 1,183,000 ========= Nuclear: 29.1% owned or leased Units 1, 2 and 3 at Palo Verde, representing................. 1,086,300 ========= Other................................................................................... 5,600 ========= - --------------- (1) West Phoenix steam units (108,300 kW) are currently mothballed. ----------------------------------------------------- Reserve Margin The Company's peak one-hour demand on its electric system was recorded on August 22, 1997 at 4,608,600 kW, compared to the 1996 peak of 4,574,700 kW recorded on July 31. Taking into account additional capacity then available to it under purchase power contracts as well as its own generating capacity, the Company's capability of meeting system demand on August 22, 1997, computed in accordance with accepted industry practices, amounted to 4,544,600 kW, for an installed reserve margin of (1.5%). The power actually available to the Company from its resources fluctuates from time to time due in part to planned outages and technical problems. The available capacity from sources actually operable at the time of the 1997 peak amounted to 5,877,600 kW, for a margin of 9.1%. Firm purchases from neighboring utilities totaling 1,603,000 kW were in place at the time of the peak ensuring the ability to meet the load requirement. Plant Sites Leased from Navajo Nation NGS and Four Corners are located on land held under easements from the federal government and also under leases from the Navajo Nation. The risk with respect to enforcement of these easements and leases is not deemed by the Company to be material. The lease for Four Corners contains a waiver until 2001 of the requirement that the Company and its fuel supplier pay certain taxes to the Navajo Nation. In September 1997, a settlement agreement was finalized between the Company, the coal supplier to Four Corners, and the Navajo Nation which settled certain issues in the Four Corners lease regarding the obligation of the fuel supplier to pay taxes prior to the expiration of tax waivers in 2001. Pursuant to the agreement, the Company recognized approximately $14 million of pretax earnings related to a partial refund of possessory interest taxes paid by the fuel supplier. The parties also 12 agreed to renegotiate their business relationship before 2001 in an effort to permit the electricity generated at Four Corners to be priced competitively. The Company cannot currently predict the outcome of this matter. Certain of the Company's transmission lines and almost all of its contracted coal sources are also located on Indian reservations. See "Generating Fuel and Purchased Power - --- Coal Supply" in Item 1. Palo Verde Nuclear Generating Station Palo Verde Leases On August 18, 1986 and December 19, 1986, the Company entered into a total of three sale and leaseback transactions under which it sold and leased back approximately 42% of its 29.1% ownership interest in Palo Verde Unit 2. The leases under each of the sale and leaseback transactions have initial lease terms expiring on December 31, 2015. Each of the leases also allows the Company to extend the term of the lease and/or to repurchase the leased Unit 2 interest under certain circumstances at fair market value. The leases in the aggregate require annual payments of approximately $40 million through 1999, approximately $46 million in 2000 and approximately $49 million through 2015 (see Note 9 of Notes to Financial Statements in Item 8). Regulatory Operation of each of the three Palo Verde units requires an operating license from the NRC. Full power operating licenses for Units 1, 2 and 3 were issued by the NRC in June 1985, April 1986 and November 1987, respectively. The full power operating licenses, each valid for a period of approximately 40 years, authorize the Company, as operating agent for Palo Verde, to operate the three Palo Verde units at full power. Nuclear Decommissioning Costs See Note 13 of Notes to Financial Statements in Item 8 for a discussion of the Company's nuclear decommissioning costs. Steam Generators See "Palo Verde Nuclear Generating Station" in Note 12 of Notes to Financial Statements in Item 8 for a discussion of issues relating to the Palo Verde steam generators. Palo Verde Liability and Insurance Matters See "Palo Verde Nuclear Generating Station" in Note 12 of Notes to Financial Statements in Item 8 for a discussion of the insurance maintained by the Palo Verde participants, including the Company, for Palo Verde.

The Company's major transmission lines shown on such map are reflected as running between the power plants named above and certain major cities in the State of Arizona. The transmission lines operated for others shown on such map are reflected as running from the Four Corners Plant through a portion of northern Arizona to the California border. 14 ITEM 3. LEGAL PROCEEDINGS Property Taxes See "Environmental Matters" and "Water Supply" in Item 1 in regard to pending or threatened litigation and other disputes. See "Regulatory Matters" in Note 3 of Notes to Financial Statements in Item 8 for a discussion of competition and the Rules regarding the introduction of retail electric competition in Arizona. On February 28, 1997, a lawsuit was filed by the Company to protect its legal rights regarding the Rules and in its complaint the Company asked the Court for (i) a judgment vacating the retail electric competition rules, (ii) a declaratory judgment that the rules are unlawful because, among other things, they were entered into without proper legal authorization, and (iii) a permanent injunction barring the ACC from enforcing or implementing the rules and from promulgating any other regulations without lawful authority (Arizona Public Service Company v. The Arizona Corporation Commission, in the Superior Court of the State of Arizona in and for the County of Maricopa, No. CV97-03753, and Arizona Public Service Company v. The Arizona Corporation Commission, in the Court of Appeals, State of Arizona, Division One, No. 1 CA-CC-97-0002, ACC Docket No. R-0000-94-165). That lawsuit is pending but two related cases filed by other utilities have been decided adversely to the utilities' positions. ITEM 4.

FINANCIAL REVIEW References to "Notes" in the following discussion refer to Notes to Financial Statements. Results of Operations 1997 Compared with 1996 The Company's 1997 earnings increased $12.3 million (5.4%) over 1996 earnings primarily because of customer growth; a $32 million pretax charge in 1996 for a voluntary severance program; two fuel-related settlements; and lower financing costs. These positive factors more than offset the effects of the Company's 1996 regulatory agreement with the ACC, which during 1997 resulted in approximately $60 million of additional regulatory asset amortization and a $35 million revenue decrease caused by two retail price reductions. See Note 3 and "Results of Operations --- Regulatory Agreements" below for additional information about the 1996 regulatory agreement. In 1996, the Company also recognized $12 million of income tax benefits, which were not repeated in 1997. The Company's operating revenues increased $160 million primarily because of increases in sales for resale ($128 million); customer growth ($58 million); and weather effects ($7 million). As mentioned in the preceding paragraph, these positive factors were partially offset by a $35 million revenue decrease caused by retail price reductions. Sales for resale are wholesale electricity sales to third parties who resell the electricity to their customers. The increase in sales for resale was a result of increased activity in competitive bulk power markets. The increase in sales for resale did not significantly affect earnings because it was substantially offset by power purchases. The two fuel-related settlements increased the Company's 1997 pretax earnings by approximately $21 million. The Company's income statement reflects these settlements as reductions in fuel expense and as other income. Approximately $16 million of these settlements related to years prior to 1997 and $5 million related to 1997. For at least the next several years, the total annual savings from the settlements are expected to be about $10 million before income taxes. The Company does not have a fuel adjustment clause as part of its retail rate structure. As a result, changes in fuel and purchased power expenses are reflected in current earnings. Operations and maintenance expenses were lower in 1997 because of the charge for the voluntary severance program recorded in 1996 and related savings in 1997. These savings were partially offset by increased expenses for marketing, information technology and power plant maintenance. The Company's financing costs decreased $12 million during 1997 because of lower amounts of outstanding debt and preferred stock. 1996 Compared with 1995 The Company's 1996 earnings increased $5.9 million (2.7%) over 1995 earnings primarily because of customer growth and higher residential usage; weather effects; tax and interest savings; and a $21 million pretax write-down of certain assets in 1995. These positive factors more than offset the earnings effects of the Company's 1996 regulatory agreement with the ACC, which during 1996 resulted in $60 million of additional regulatory asset amortization and a $30 million revenue decrease caused by a retail price reduction. See Note 3 and "Results of Operations --- Regulatory Agreements" below for additional information about the 1996 regulatory agreement. Other important factors that made the comparison of 1996 earnings with 1995 earnings less favorable were a $32 million pretax charge for a voluntary severance program; the recognition in 1995 of a $5 million after-tax gain on the sale of a small subsidiary; and increased fuel expenses of $56 million primarily because of increased retail and wholesale sales, higher natural gas costs, and higher coal prices. 19 The Company's operating revenues increased $103 million primarily because of retail customer growth and higher residential usage ($75 million); weather effects ($40 million); increases in sales for resale ($9 million); and other ($9 million). As mentioned above, these positive factors were partially offset by a $30 million revenue decrease caused by a retail price reduction. Other taxes decreased $21 million primarily because of a change in property tax law. Income tax expense was lower because of the Company's recognition of $12 million of income tax benefits associated with capital loss carryforwards. The Company's financing costs decreased $12 million during 1996 because of lower average interest rates and lower amounts of outstanding debt. Regulatory Agreements The Company's results of operations are affected, and will be affected, by the impacts of existing regulatory agreements between the Company and the ACC. As part of the 1996 regulatory agreement with the ACC, the Company is recovering substantially all of its present regulatory assets through accelerated amortization over an eight-year period that began July 1, 1996. See Note 3. This accelerated amortization increases annual amortization expense by approximately $120 million ($72 million after taxes). Also as part of the 1996 regulatory agreement, the Company agreed to decrease retail prices effective July 1, 1996 by approximately $48.5 million annually ($29 million after income taxes), or 3.4%. In addition, the Company agreed to share future cost savings with its customers through potential additional retail price reductions. Pursuant to the agreed-upon price reduction formula, on July 1, 1997, the Company reduced its retail prices by approximately $17.6 million annually ($10.5 million after income taxes), or 1.2%. Additionally, in March 1998, the Company filed with the ACC its calculation of an additional retail price decrease of approximately $17 million annually ($10 million after income taxes), or 1%, to become effective July 1, 1998. The amount and timing of the price decrease are subject to ACC approval. The factors that offset the earnings impact of the accelerated regulatory asset amortization and the 1997 and 1996 price decreases are discussed above in "Results of Operations." As part of a 1994 rate settlement with the ACC, the Company accelerated amortization of substantially all deferred investment tax credits (ITCs) over a five-year period that ends on December 31, 1999. The amortization of ITCs is shown on the Company's income statement as Other Income --- Income Taxes and decreases annual income tax expense by approximately $28 million. See Note 10. Capital Needs and Resources The Company's capital requirements consist primarily of capital expenditures and optional and mandatory redemptions of long-term debt and preferred stock. The Company funds its capital requirements from cash provided by operations, annual equity infusions from its parent company of $50 million from 1996 through 1999 (see Note 3), and, to the extent necessary, external financing. During the period 1995 through 1997, the Company funded all of its capital expenditures from cash provided by operations and expects to do so in 1998 through 2000 as well. During 1997, the Company redeemed approximately $240 million of long-term debt and $47 million of preferred stock, including premiums, with cash from operations and long- and short-term debt. The Company's projected capital expenditures for the next three years are: 1998, $323 million; 1999, $313 million; and 2000, $306 million. These amounts include about $30-$35 million each year for nuclear fuel. In general, most of the projected capital expenditures are for expanding transmission and distribution capabilities to 20 meet customer growth, for upgrading existing facilities and for environmental purposes. In addition, the Company is considering expanding certain of its businesses over the next several years, which may result in increased expenditures. The Company's construction plans through the year 2007 do not include any major baseload generating plants. The Company's long-term debt and preferred stock redemption requirements and payment obligations on a capitalized lease for the next three years are: 1998, $114 million; 1999, $174 million; and 2000, $114 million. Based on cash provided by operations and the Company's capital requirements, the Company may make optional redemptions of long-term debt and preferred stock from time to time. As of December 31, 1997, the Company had credit commitments from various banks totaling approximately $400 million, which were available either to support the issuance of commercial paper or to be used as bank borrowings. At the end of 1997, there were $130.8 million of commercial paper and $150 million of bank borrowings outstanding. During 1997, the Company incurred $60 million of long-term debt under credit agreements and issued $50 million of its senior notes. Until the Company has repaid all of its first mortgage bonds (other than those that secure senior notes), the senior notes are secured by first mortgage bonds that have the same interest rate, interest payment dates, maturity and redemption provisions as the senior notes. See Note 5 for additional information regarding the senior notes. In January 1998, the Company issued $100 million of unsecured debt. Although provisions in the Company's first mortgage bond indenture, articles of incorporation, and ACC financing orders establish maximum amounts of additional first mortgage bonds and preferred stock that the Company may issue, management does not expect any of these provisions to limit the Company's ability to meet its capital requirements. Competition and Industry Restructuring The electric industry is undergoing significant change to a competitive, market-based structure from a highly-regulated, cost-based environment in which companies have been entitled to recover their costs and to earn fair returns on their invested capital in exchange for commitments to serve all customers within designated service territories. In December 1996, the ACC adopted rules that provide a framework for the introduction of retail electric competition in Arizona in phases from 1999 to 2003. See Note 3 for additional information about these rules and other competitive developments. The ACC ordered in the rules that numerous issues require additional consideration prior to the implementation of retail electric competition in Arizona. During 1997, the ACC held workshops to gather input from various constituencies with respect to those issues. The rules indicate that the ACC will allow recovery of unmitigated stranded costs, but do not set forth the mechanisms for determining and recovering such costs. In February 1998, the ACC completed a formal, generic hearing on stranded cost determination and recovery. Based on various assumptions, estimates and methodologies, the Company currently estimates that its stranded costs to be recovered (excluding regulatory assets which have already been addressed by the ACC) will be less than $500 million. The Company is seeking full recovery of stranded costs during a transition period proposed to go through 2006. Decisions by the ACC have not yet been made with respect to this issue. An Arizona joint legislative committee studied electric utility restructuring issues in 1996 and 1997. In February 1998, a bill was introduced in the Arizona legislature to facilitate implementation of retail electric competition in the state. The bill has progressed through several stages to date. Additionally, legislation related to electric competition has been proposed in the United States Congress. See Note 3 for a discussion of legislative developements. 21 The Company believes that further ACC decisions, legislation at the Arizona and federal levels and perhaps amendments to the Arizona Constitution will ultimately be required before significant implementation of retail electric competition can lawfully occur in Arizona. Until it has been determined how competition will be implemented in Arizona, including the manner in which stranded costs will be addressed, the Company cannot accurately predict the impact of full retail competition on its financial position, cash flows or results of operations. As competition in the electric industry continues to evolve, the Company will continue to evaluate strategies and alternatives that will position the Company to compete effectively in a restructured industry. The Company prepares its financial statements in accordance with the provisions of Statement of Financial Accounting Standards (SFAS) No. 71, "Accounting for the Effects of Certain Types of Regulation." SFAS No. 71 requires a cost-based, rate-regulated enterprise to reflect the impact of regulatory decisions in its financial statements. The Company's existing regulatory orders and current regulatory environment support its accounting practices related to regulatory assets which amounted to approximately $1.0 billion at December 31, 1997. In accordance with the 1996 regulatory agreement, the ACC accelerated the amortization of substantially all of the Company's regulatory assets to an eight-year period that began July 1, 1996. If the Company ceases to be cost-based regulated, it would no longer be able to apply the provisions of SFAS No. 71 to all or some part of its operations, which could have a material impact on the Company's financial statements. See Note 1 for additional information on regulatory accounting. Year 2000 Technology Issues The Company has made, and will continue to make, certain modifications to its computer hardware and software systems and applications to ensure they are capable of handling dates in the year 2000 and thereafter. The Company's major computer systems have been updated and other systems are being analyzed for potential modifications. The financial impact on the Company is not anticipated to be material to is financial position, cash flows or results of operations. The Company is in the process of formal communications with its significant suppliers, business partners, and large customers to determine the extent to which it may be affected by these third parties' plans to remediate their own year 2000 issues in a timely manner. Accounting Matters Note 2 describes three new accounting standards related to comprehensive income, segment disclosures and disclosures about pensions and other postretirement benefits, which are effective in 1998. These standards are not expected to have a material effect on the Company's financial position, cash flows or results of operation. Also, see Note 13 for a description of a proposed standard on accounting for certain liabilities related to closure or removal of long-lived assets. Risk Management The Company's operations include managing market risks related to changes in interest rates, commodity prices and investments held by the nuclear decommissioning trust fund. Interest Rate and Equity Risk The Company's major financial market risk exposure is changing interest rates. Changing interest rates will affect interest paid on variable rate debt and interest earned by the nuclear decommissioning trust fund. The Company's policy is to manage interest rates through the use of a combination of fixed and floating rate debt. The nuclear decommissioning fund also has risks associated with changing market values of equity investments. Nuclear decommissioning costs are recovered in rates. 22 The table below presents contractual balances of the Company's long-term debt and commercial paper at the expected maturity dates as well as the fair value of those instruments on December 31, 1997. The weighted average interest rates for the various debt presented are actual as of December 31, 1997.

Most of these agreements are settled in physical delivery, with the balance settled in cash at or prior to expiration. Under certain of these agreements, payments are sometimes made or received based on the differential between a fixed and a variable product price. The Company does not obtain collateral to support the agreements, but monitors the financial viability of counterparties and believes it has minimized its credit risk on these transactions. In the event of nonperformance by counterparties, the Company would be exposed to price risk. The Company may recognize an accounting gain or loss where actual delivery occurs and the price in the contract may differ from the prevailing price at the delivery point in completing the transaction. The Company defers the impact of changes in the market value of contracts that serve as hedges until the related transaction is completed. Forward-Looking Statements The above discussion contains forward-looking statements that involve risks and uncertainties. Words such as "estimates," "expects," "anticipates," "plans," "believes," "projects," and similar expressions identify forward-looking statements. These risks and uncertainties include, but are not limited to, the ongoing restructuring of the electric industry; the outcome of the regulatory proceedings relating to the restructuring; regulatory, tax and environmental legislation; the ability of the Company to successfully compete outside its traditional regulated markets; regional economic conditions, which could affect customer growth; the cost of debt and equity capital; weather variations affecting customer usage; and technological developments in the electric industry. These factors and the other matters discussed above may cause future results to differ materially from historical results, or from results or outcomes currently expected or sought by the Company. 23 ITEM 8.

Such information was prepared in accordance with generally accepted accounting principles appropriate in the circumstances, based on management's best estimates and judgments and giving due consideration to materiality. These financial statements have been audited by independent auditors and their report is included. Management maintains and relies upon systems of internal accounting controls. A limiting factor in all systems of internal accounting control is that the cost of the system should not exceed the benefits to be derived. Management believes that the Company's system provides the appropriate balance between such costs and benefits. Periodically the internal accounting control system is reviewed by both the Company's internal auditors and its independent auditors to test for compliance. Reports issued by the internal auditors are released to management, and such reports or summaries thereof are transmitted to the Audit Review Committee of the Board of Directors and the independent auditors on a timely basis. The Audit Review Committee, composed solely of outside directors, meets periodically with the internal auditors and independent auditors (as well as management) to review the work of each. The internal auditors and independent auditors have free access to the Audit Review Committee, without management present, to discuss the results of their audit work. Management believes that the Company's systems, policies and procedures provide reasonable assurance that operations are conducted in conformity with the law and with management's commitment to a high standard of business conduct. William J. Post George A. Schreiber, Jr. William J. Post George A. Schreiber, Jr. President and Executive Vice President Chief Executive Officer and Chief Financial Officer 25 INDEPENDENT AUDITORS' REPORT We have audited the accompanying balance sheets of Arizona Public Service Company as of December 31, 1997 and 1996 and the related statements of income, retained earnings and cash flows for each of the three years in the period ended December 31, 1997. 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 in accordance with generally accepted auditing standards. Those standards 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. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, such financial statements present fairly, in all material respects, the financial position of the Company at December 31, 1997 and 1996 and the results of its operations and its cash flows for each of the three years in the period ended December 31, 1997 in conformity with generally accepted accounting principles.

APS NOTES TO FINANCIAL STATEMENTS 1. Summary of Significant Accounting Policies Nature of Operations The Company is Arizona's largest electric utility, with 767,000 customers, and provides wholesale or retail electric service to the entire state of Arizona with the exception of Tucson and about one-half of the Phoenix area. Accounting Records The accounting records are maintained in accordance with generally accepted accounting principles (GAAP). The preparation of financial statements in accordance with GAAP requires the use of estimates by management. Actual results could differ from those estimates. Regulatory Accounting The Company is regulated by the ACC and the FERC and the accompanying financial statements reflect the rate-making policies of these commissions. The Company prepares its financial statements in accordance with the provisions of Statement of Financial Accounting Standards (SFAS) No. 71, "Accounting for the Effects of Certain Types of Regulation." SFAS No. 71 requires a cost-based, rate-regulated enterprise to reflect the impact of regulatory decisions in its financial statements. The Company's major regulatory assets are deferred income taxes (see Note 10) and rate synchronization cost deferrals (see "Rate Synchronization Cost Deferrals" in this note). These items, combined with miscellaneous regulatory assets and liabilities, amounted to approximately $1.0 billion and $1.1 billion at December 31, 1997 and 1996, respectively, most of which are included in "Deferred Debits" on the Balance Sheets. In accordance with the 1996 regulatory agreement (see Note 3), the ACC accelerated the amortization of substantially all of the Company's regulatory assets to an eight-year period that began July 1, 1996. The accelerated portion of the regulatory asset amortization, approximately $120 million pretax in 1997 and $60 million pretax in 1996, is included in depreciation and amortization expense on the Statements of Income. 31 APS NOTES TO FINANCIAL STATEMENTS During 1997, the Emerging Issues Task Force (EITF) of the Financial Accounting Standards Board (FASB) issued EITF 97-4, which requires that SFAS No. 71 be discontinued no later than when legislation is passed or a rate order is issued that contains sufficient detail to determine its effect on the portion of the business being deregulated, which could result in write-downs or write-offs of physical and/or regulatory assets. Additionally, the EITF determined that regulatory assets should not be written off if they are to be recovered from a portion of the entity which continues to apply SFAS No. 71. Although the ACC has issued rules for transitioning generation services to competition, there are many unresolved issues. The Company continues to apply SFAS No. 71 to all of its operations. If rate recovery of regulatory assets is no longer probable, whether due to competition or regulatory action, the Company would be required to write off the remaining balance as an extraordinary charge to expense. Common Stock All of the outstanding shares of common stock of the Company are owned by Pinnacle West. See Note 4. Utility Plant and Depreciation Utility plant represents the buildings, equipment and other facilities used to provide electric service. The cost of utility plant includes labor, materials, contract services, other related items and capitalized interest or an allowance for funds used during construction. The cost of retired depreciable utility plant, plus removal costs less salvage realized, is charged to accumulated depreciation. See Note 13 for information on a proposed accounting standard which impacts accounting for removal costs. Depreciation on utility property is recorded on a straight-line basis. The applicable rates as prescribed by regulators for 1995 through 1997 ranged from 1.51% to 20%, which resulted in an annual composite rate of 3.35% for 1997. Depreciation and amortization of non-utility property and equipment are provided over the estimated useful lives of the related assets, ranging from 3 to 50 years. Capitalized Interest In 1997 the Company began capitalizing interest in accordance with SFAS No. 34, "Capitalization of Interest Cost." Capitalized interest represents the cost of debt funds used to finance construction of utility plant. Plant construction costs, including capitalized interest, are recovered in authorized rates through depreciation when completed projects are placed into commercial operation. Capitalized interest does not represent current cash earnings. The rate used to calculate capitalized interest for 1997 was 7.25%. Prior to 1997 the Company accrued an allowance for funds used during construction (AFUDC). AFUDC represented the cost of debt and equity funds used to finance construction of utility plant, and did not represent current cash earnings. AFUDC has been calculated using composite rates of 7.75% for 1996 and 8.52% for 1995. Revenues Electric operating revenues are recognized on the accrual basis and include estimated amounts for service rendered but unbilled at the end of each accounting period. Rate Synchronization Cost Deferrals As authorized by the ACC, operating costs (excluding fuel) and financing costs of Palo Verde Units 2 and 3 were deferred from the commercial operation dates (September 1986 and January 1988, respectively) until the date the units were included in a rate order (April 1988 and December 1991, respectively). Beginning July 1, 1996, the deferrals are being amortized over an eight-year period in accordance with the 1996 regulatory agreement (see Note 3). Prior to July 1, 1996 the deferrals were amortized over thirty-five year periods. Amortization of the deferrals is included in depreciation and amortization expense on the Statements of Income. 32 APS NOTES TO FINANCIAL STATEMENTS Nuclear Fuel Nuclear fuel is charged to fuel expense using the unit-of-production method under which the number of units of thermal energy produced in the current period is related to the total thermal units expected to be produced over the remaining life of the fuel. Under federal law, the United States Department of Energy (DOE) is responsible for the permanent disposal of spent nuclear fuel and assesses $0.001 per kWh of nuclear generation. This amount is charged to nuclear fuel expense. See Note 12 for information on spent fuel disposal and Note 13 for information on nuclear decommissioning costs. Reacquired Debt Costs The Company amortizes gains and losses on reacquired debt over the remaining life of the original debt, consistent with ratemaking. In accordance with the 1996 regulatory agreement (see Note 3), the ACC accelerated the Company's amortization of the regulatory asset for reacquired debt costs to an eight-year period that began July 1, 1996. The accelerated portion of the regulatory asset amortization is included in depreciation and amortization expense on the Statements of Income. Cash and Cash Equivalents For purposes of the statements of cash flows, the Company considers all highly liquid debt instruments purchased with an initial maturity of three months or less to be cash equivalents. Reclassifications Certain prior year balances have been restated to conform to the 1997 presentation. 2. Accounting Matters The Financial Accounting Standards Board has issued SFAS No. 130 "Reporting Comprehensive Income," SFAS No. 131 "Disclosures about Segments of an Enterprise and Related Information" and SFAS No. 132 "Employers' Disclosures about Pensions and Other Postretirement Benefits," all of which are effective in 1998. SFAS No. 130 changes the reporting of certain items currently reported in the common stock equity section of the balance sheet and is not expected to have a material effect on the Company's financial statements. SFAS No. 131 requires that public companies report certain information about operating segments in their financial statements. It also establishes related disclosures about products and services, geographic areas, and major customers. The Company is currently evaluating what impact this standard will have on its disclosures. SFAS No. 132 standardizes the disclosure requirements for pensions and other postretirement benefits to provide information that is more comparable, understandable and concise. It is not expected to have a material effect on the Company's financial statement disclosures. 3. Regulatory Matters Electric Industry Restructuring State The ACC has been conducting an ongoing investigation into the restructuring of the Arizona electric industry. In December 1996, the ACC adopted rules that provide a framework for the introduction of retail electric competition. The ACC framework rules include the following major provisions: o The rules are intended to apply to virtually all of the Arizona electric utilities regulated by the ACC, including the Company. 33 APS NOTES TO FINANCIAL STATEMENTS o Each affected utility would be required to make available at least 20% of its 1995 system retail peak demand for competitive generation supply to all customer classes not later than January 1, 1999; at least 50% not later than January 1, 2001; and all of its retail demand not later than January 1, 2003. o Electric service providers that obtain Certificates of Convenience and Necessity (CC&Ns) from the ACC would be allowed to supply, market, and/or broker specified electric services at retail. These services would include electric generation, but exclude electric transmission and distribution. o On or before December 31, 1997, each affected utility was required to file with the ACC proposed tariffs for bundled service, if different than current tariffs, and unbundled service. Bundled service means electric service elements (i.e., generation, transmission, distribution, and ancillary services) provided as a package to consumers within an affected utility's current service area. Unbundled service means electric service elements provided and priced separately. o The rules indicate that the ACC will allow recovery of unmitigated stranded costs. Stranded costs are the costs of generating plants, other assets and contract commitments that were prudently incurred to serve power customers that could go unrecovered if these customers are allowed to use open access to move to another supplier. Each affected utility would be required to file with the ACC its estimates of unmitigated stranded costs. The ACC would then, after hearing and consideration of various factors, determine the magnitude of stranded costs and appropriate stranded cost recovery mechanisms and charges. The ACC ordered in the rules that numerous issues (including reliability; stranded cost measurement and recovery; the phase-in process, bundled, unbundled and metering services; legal issues; and independent system operator and spot market development) require additional consideration prior to implementation of retail electric competition. During 1997, the ACC conducted workshops to gather input from various constituencies with respect to those issues. In February 1998, the ACC completed a formal, generic hearing on stranded cost determination and recovery. Based on various assumptions, estimates and methodologies, the Company currently estimates that its stranded costs to be recovered (excluding regulatory assets which have already been addressed by the ACC) will be less than $500 million. The Company is seeking full recovery of stranded costs during a transition period proposed to go through 2006. Decisions by the ACC have not yet been made with respect to this issue. An Arizona joint legislative committee studied electric utility industry restructuring issues in 1996 and 1997. In conjunction with that study, Arizona legislative counsel prepared memoranda in late 1997 related to the legal authority of the ACC to deregulate the Arizona electric utility industry. The memoranda raise a question as to the degree to which the ACC may, under the Arizona Constitution, deregulate any portion of the electric utility industry and allow rates to be determined by market forces. In February 1998, a bill to facilitate implementation of retail electric competition in the state was introduced in the Arizona legislature. The bill has progressed through several stages to date. The bill includes the following major provisions: (a) requirements that large government-operated electric utilities (i) enter into intergovernmental agreements with the ACC to promote consistent statewide practices; (ii) implement retail electric generation competition for 20% of each utility's 1995 retail peak demand by December 31, 1998 and for all customers by December 31, 1999; (iii) decrease rates by at least 10% over a ten- year period beginning as early as January 1, 1991; and (iv) recover unmitigated stranded costs through a surcharge on distribution prices; and (b) a proposal that the ACC adopt provisions for public service corporations (including investor-owned utilities such as APS) consistent with some of the bill's provisions for certain government-operated electric utilities as described above. 34 APS NOTES TO FINANCIAL STATEMENTS The Company believes that certain provisions of the ACC framework rules are deficient. In February 1997, a lawsuit was filed by the Company to protect its legal rights regarding those rules. That lawsuit is pending but two related cases filed by other utilities have been decided adversely to the utilities' positions. The Company believes that further ACC decisions, legislation at the Arizona and federal levels and perhaps amendments to the Arizona Constitution (which amendments would require a vote of the people) will ultimately be required before significant implementation of retail electric competition can lawfully occur in Arizona. Until the manner of implementation of competition, including addressing stranded costs, is determined, the Company cannot accurately predict the impact of full retail competition on its financial position, cash flows or results of operation. As competition in the electric industry continues to evolve, the Company will continue to evaluate strategies and alternatives that will position the Company to compete in the new regulatory environment. Federal The Energy Policy Act of 1992 and recent rulemakings by FERC have promoted increased competition in the wholesale electric power markets. The Company does not expect these rules to have a material impact on its financial statements. Several electric utility reform bills have been introduced during recent congressional sessions, which as currently written, would allow consumers to choose their electricity suppliers by 2000 or 2003. These bills, other bills that are expected to be introduced, and ongoing discussions at the federal level suggest a wide range of opinion that will need to be narrowed before any substantial restructuring of the electric utility industry can occur. 1996 Regulatory Agreement In April 1996, the ACC approved a regulatory agreement between the Company and the ACC Staff. The major provisions of this agreement are: o An annual rate reduction of approximately $48.5 million ($29 million after income taxes), or 3.4% on average for all customers except certain contract customers, effective July 1, 1996. o Recovery of substantially all of the Company's present regulatory assets through accelerated amortization over an eight-year period that began July 1, 1996, increasing annual amortization by approximately $120 million ($72 million after income taxes). See Note 1. o A formula for sharing future cost savings between customers and shareholders (price reduction formula) referencing a return on equity (as defined) of 11.25%. o A moratorium on filing for permanent rate changes prior to July 2, 1999, except under the price reduction formula and under certain other limited circumstances. o Infusion of $200 million of common equity into the Company by Pinnacle West, in annual payments of $50 million starting in 1996. Pursuant to the price reduction formula, in May 1997, the ACC approved a retail price decrease of approximately $17.6 million ($10.5 million after income taxes), or 1.2%, effective July 1, 1997. In March 1998, the Company filed with the ACC its calculation of an annual price reduction of approximately $17 million ($10 million after income taxes), or 1%, to become effective July 1, 1998. The amount and timing of the price decrease are subject to ACC approval. 35 APS NOTES TO FINANCIAL STATEMENTS 4.

(b) The weighted-average rate for the years ended December 31, 1997 and 1996 was 3.62% and 3.40%, respectively. Changes in short-term interest rates would affect the costs associated with this debt. (c) The Company has issued $150 million of first mortgage bonds ("senior note mortgage bonds") to the senior note trustee as collateral for the senior notes. The senior note mortgage bonds have the same interest rate, interest payment dates, maturity, and redemption provisions as the senior notes. The Company's payments of principal, premium, and/or interest on the senior notes satisfy the Company's corresponding payment obligations on the senior note mortgage bonds. As long as the senior note mortgage bonds secure the senior notes, the senior notes will effectively rank pari passu with the first mortgage bonds. On the date that the Company has repaid all of its first mortgage bonds, other than those that secure senior notes, the senior note mortgage bonds will no longer secure the senior notes and will cease to be outstanding. 38 APS NOTES TO FINANCIAL STATEMENTS (d) The weighted-average rate at December 31, 1997 and 1996 was 6.25% and 5.76%, respectively. Changes in short-term interest rates would affect the costs associated with this debt. (e) Represents the present value of future lease payments (discounted at an interest rate of 7.48%) on a combined cycle plant sold and leased back from the independent owner-trustee formed to own the facility (see Note 9). Aggregate annual principal payments due on total long-term debt and for sinking fund requirements through 2002 are as follows: 1998, $104.1 million; 1999, $164.4 million; 2000, $104.7 million; 2001, $2.5 million; and 2002, $275 million. See Note 4 for redemption and sinking fund requirements of redeemable preferred stock of the Company. Substantially all utility plant (other than nuclear fuel, transportation equipment and the combined cycle plant) is subject to the lien of the mortgage bond indenture. The mortgage bond indenture includes provisions which would restrict the payment of common stock dividends under certain conditions which did not exist at December 31, 1997. 6. Lines of Credit The Company had committed lines of credit with various banks of $400 million at December 31, 1997 and 1996, which were available either to support the issuance of commercial paper or to be used for bank borrowings. The commitment fees at December 31, 1997 and 1996 for these lines of credit ranged from .07% to .15% per annum. The Company had long-term bank borrowings of $150 million and $100 million outstanding at December 31, 1997 and 1996, respectively, under these lines of credit. The Company had commercial paper borrowings outstanding of $130.8 million and $16.9 million at December 31, 1997 and 1996, respectively. The weighted average interest rate on commercial paper borrowings was 6.27% and 6.40% on December 31, 1997 and 1996, respectively. By Arizona statute, the Company's short-term borrowings cannot exceed 7% of its total capitalization without the consent of the ACC. 7. Fair Value of Financial Instruments The Company estimates that the carrying amounts of its cash equivalents and commercial paper are reasonable estimates of their fair values at December 31, 1997 and 1996 due to their short maturities. Investments in debt and equity securities are held for purposes other than trading. The December 31, 1997 and 1996 fair values of such investments, determined by using quoted market values or by discounting cash flows at rates equal to the Company's cost of capital, approximate their carrying amounts. The carrying value of long-term debt (excluding a capitalized lease obligation) on December 31, 1997 and 1996 was $2.04 billion and $2.16 billion, respectively, and the estimated fair value was $2.08 billion and $2.13 billion, respectively. The fair value estimates are based on quoted market prices of the same or similar issues. 39 APS NOTES TO FINANCIAL STATEMENTS 8. Jointly-Owned Facilities At December 31, 1997, the Company owned interests in the following jointly-owned electric generating and transmission facilities. The Company's share of related operating and maintenance expenses is included in utility operations and maintenance.

(b) The Company is the operating agent for Cholla Unit 4, which is owned by PacifiCorp. The common facilities at the Cholla Plant are jointly-owned. (c) Weighted average of interests. 9. Leases In 1986, the Company entered into sale and leaseback transactions under which it sold approximately 42% of its share of Palo Verde Unit 2 and certain common facilities. The gain of approximately $140.2 million has been deferred and is being amortized to operations expense over the original lease term. The leases are being accounted for as operating leases. The amounts to be paid each year approximate $40.1 million through 1999, $46.3 million in 2000 and $49.0 million through 2015. Options to renew for two additional years and to purchase the property at fair market value at the end of the lease terms are also included. Consistent with the 40 APS NOTES TO FINANCIAL STATEMENTS ratemaking treatment, an amount equal to the annual lease payments is included in rent expense. A regulatory asset is recognized for the difference between lease payments and rent expense calculated on a straight-line basis. In accordance with the 1996 regulatory agreement (see Note 3), the ACC accelerated the Company's amortization of the regulatory asset for leases to an eight-year period that began July 1, 1996. The accelerated amortization is included in depreciation and amortization expense on the Statements of Income. The balance of this regulatory asset at December 31, 1997 was $53.2 million. Lease expense was approximately $42 million in each of the years 1995 through 1997. The Company has a capital lease on a combined cycle plant which it sold and leased back. The lease requires semiannual payments of $2.6 million through June 2001, and includes renewal and purchase options based on fair market value. This plant is included in plant in service at its original cost of $54.4 million; accumulated amortization at December 31, 1997 was $46.5 million. In addition, the Company leases certain land, buildings, equipment and miscellaneous other items through operating rental agreements with varying terms, provisions and expiration dates. Rent expense for 1997, 1996 and 1995 was approximately $7.8 million, $9.7 million and $9.9 million, respectively. Annual future minimum rental commitments, excluding the Palo Verde and combined cycle leases, for the period 1998 through 2002 range between $13 million and $15 million. Total rental commitments after the year 2002 are estimated at $99 million. 10. Income Taxes The Company is included in the consolidated income tax returns of Pinnacle West. Income taxes are allocated to the Company based on its separate company taxable income or loss. Beginning in 1995, substantially all ITCs are being amortized over a five-year period in accordance with a 1994 rate settlement agreement. The Company follows the liability method of accounting for income taxes which requires that deferred income taxes be recorded for all temporary differences between the tax bases of assets and liabilities and the amounts recognized for financial reporting. Deferred taxes are recorded using currently enacted tax rates. In accordance with SFAS No. 71, a regulatory asset has been established for certain temporary differences, primarily AFUDC equity, to reflect the ratemaking treatment. This regulatory asset is being amortized as the related differences reverse. In accordance with the 1996 regulatory agreement (see Note 3), the ACC accelerated the Company's amortization of the regulatory asset for income taxes to an eight-year period beginning July 1, 1996. The accelerated portion of the regulatory asset amortization is included in depreciation and amortization expense on the Statements of Income. 41 APS NOTES TO FINANCIAL STATEMENTS The components of income tax expense are as follows: Year Ended December 31, --------------------------------------- 1997 1996 1995 --------- --------- --------- (Thousands of Dollars) Current: Federal ................................................. $ 187,701 $ 137,531 $ 120,196 State ................................................... 48,531 35,777 33,368 --------- --------- --------- Total current ............................ 236,232 173,308 153,564 Deferred ...................................................

Retirement Plans and Other Benefits Voluntary Severance Plan The Company sponsored a voluntary severance plan in 1996, which resulted in a pretax charge of $31.7 million (including pension and postretirement benefit expense) recorded primarily as operations and maintenance expense. Employees participating in the plan were credited with an additional year of age and service for purposes of calculating pension and postretirement benefits. The total additional pension and postretirement benefit expense recorded in 1996 for this program was $2.3 million and $5.4 million, respectively. Pension Plan The Company sponsors a defined benefit pension plan covering substantially all employees. Benefits are based on years of service and compensation utilizing a final average pay benefit formula. Company policy is to fund not less than the minimum required contribution nor greater than the maximum tax-deductible contribution. Plan assets consist primarily of domestic and international common stocks and bonds and real estate. Pension expense, including administrative and severance costs, for 1997, 1996 and 1995 was approximately $8.7 million, $14.9 million and $9.6 million, respectively. 43 APS NOTES TO FINANCIAL STATEMENTS The components of net periodic pension costs before consideration of amounts capitalized or billed to others and excluding severance costs of $2.9 million in 1996 are as follows: 1997 1996 1995 -------- -------- -------- (Thousands of Dollars) Service cost --- benefits earned during the period ............. $ 19,881 $ 22,861 $ 16,038 Interest cost on projected benefit obligation .................. 47,824 44,602 39,328 Return on plan assets ..........................................

Collectively, these plans cover substantially all employees. The plans provide for employee contributions and partial employer matching contributions after certain eligibility requirements are met. Expenses related to these plans for 1997, 1996 and 1995 were $3.7 million, $3.4 million and $3.1 million, respectively. Postretirement Plans The Company provides medical and life insurance benefits to its retired employees. Employees must retire to become eligible for these retirement benefits, which are based on years of service and age. The retiree medical insurance plans are contributory; the retiree life insurance plans are noncontributory. In accordance with the governing plan documents, the Company retains the right to change or eliminate these benefits. 44 APS NOTES TO FINANCIAL STATEMENTS Funding is based upon actuarially determined contributions that take tax consequences into account. Plan assets consist primarily of domestic stocks and bonds. The postretirement benefit expense for 1997, 1996 and 1995 was approximately $9.4 million, $15.8 million and $13.3 million, respectively. The components of net periodic postretirement benefit costs before consideration of amounts capitalized or billed to others and excluding severance costs of $9.6 million in 1996 are as follows: 1997 1996 1995 -------- -------- -------- (Thousands of Dollars) Service cost --- benefits earned during the period.............. $ 6,865 $ 7,974 $ 6,735 Interest cost on accumulated benefit obligation ................ 14,315 13,395 13,743 Return on plan assets ..........................................

Commitments and Contingencies Litigation The Company is a party to various claims, legal actions and complaints arising in the ordinary course of business. In the opinion of management, the ultimate resolution of these matters will not have a material adverse effect on the Company's financial statements. Palo Verde Nuclear Generating Station The Company has encountered tube cracking in steam generators and has taken, and will continue to take, remedial actions that it believes have slowed the rate of tube degradation. The projected service life of the steam generators is reassessed periodically and these analyses indicate that it will be economically desirable for the Company to replace the Unit 2 steam generators between 2003 and 2008. The Company estimates that its share of the replacement costs (in 1997 dollars and including installation and replacement power costs) will be approximately $50 million, most of which will be incurred after the year 2000. During the fourth quarter of 1997, the Palo Verde participants, including the Company, entered into a contract for the fabrication of two replacement steam generators. The cost to the Company is estimated at approximately $26 million. These generators will be used as replacements if performance of existing generators deteriorates to less than acceptable levels. The generators are expected on site in 2002. The Company's share of installation costs is approximately $24 million. Based on the latest available data, the Company estimates that the Unit 1 and Unit 3 steam generators should operate for the license periods (until 2025 and 2027, respectively), although the Company will continue its normal periodic assessment of these steam generators. Under the Nuclear Waste Policy Act, DOE was to develop the facilities necessary for the storage and disposal of spent fuel and to have the first such facility in operation by 1998. That facility was to be a permanent repository, but DOE has announced that such a repository now cannot be completed before 2010. In November 1997 the Court of Appeals for the D.C. Circuit affirmed its previous decision that DOE must begin accepting spent fuel by 1998 and issued an order precluding DOE from excusing its own delay on the grounds that DOE has not yet prepared a permanent repository or interim storage facility. The Company has capacity in existing fuel storage pools at Palo Verde which, with certain modifications, could accommodate all fuel expected to be discharged from normal operation of Palo Verde through about 2002, and believes it could augment that wet storage with new facilities for on-site dry storage of spent fuel for an indeterminate period of operation beyond 2002, subject to obtaining any required governmental approvals. The Company currently believes that spent fuel storage or disposal methods will be available for use by Palo Verde to allow its continued operation beyond 2002. The Palo Verde participants have insurance for public liability resulting from nuclear energy hazards to the full limit of liability under federal law. This potential liability is covered by primary liability insurance provided by commercial insurance carriers in the amount of $200 million and the balance by an industry-wide retrospective assessment program. If losses at any nuclear power plant covered by the programs exceed the accumulated funds, the Company could be assessed retrospective premium adjustments. The maximum assessment per reactor under the program for each nuclear incident is approximately $79 million, subject to an annual limit of $10 million per incident. Based upon the Company's 29.1% interest in the three Palo Verde units, the Company's maximum potential assessment per incident for all three units is approximately $69 million, with an annual payment limitation of approximately $9 million. 46 APS NOTES TO FINANCIAL STATEMENTS The Palo Verde participants maintain "all risk" (including nuclear hazards) insurance for property damage to, and decontamination of, property at Palo Verde in the aggregate amount of $2.75 billion, a substantial portion of which must first be applied to stabilization and decontamination. The Company has also secured insurance against portions of any increased cost of generation or purchased power and business interruption resulting from a sudden and unforeseen outage of any of the three units. The insurance coverage discussed in this and the previous paragraph is subject to certain policy conditions and exclusions. Fuel and Purchased Power Commitments The Company is a party to various fuel and purchased power contracts with terms expiring from 1998 through 2020 that include required purchase provisions. The Company estimates its 1998 contract requirements to be approximately $136 million. However, this amount may vary significantly pursuant to certain provisions in such contracts which permit the Company to decrease its required purchases under certain circumstances. The Company is contractually obligated to reimburse certain coal providers for amounts incurred for coal mine reclamation. The Company's share of the total obligation is estimated at $110 million. The portion of the coal mine reclamation obligation related to coal already burned is approximately $66 million at December 31, 1997 and is included in "Deferred Credits --- Other" in the Balance Sheet. A regulatory asset has been established for amounts not yet recovered from ratepayers. In accordance with the 1996 regulatory agreement (see Note 3), the ACC began accelerated amortization of the Company's regulatory asset for coal mine reclamation costs over an eight-year period beginning July 1, 1996. Amortization is included in depreciation and amortization expense on the Statements of Income. The balance of the regulatory asset at December 31, 1997 was approximately $60 million. Construction Program Total capital expenditures in 1998 are estimated at $323 million. 13. Nuclear Decommissioning Costs The Company recorded $11.4 million for decommissioning expense in each of the years 1997 and 1996. The Company estimates it will cost approximately $2.0 billion ($460 million in 1997 dollars), over a 14 year period beginning in 2024, to decommission its 29.1% interest in the three Palo Verde units. Decommissioning costs are charged to expense over the respective unit's operating license term and are included in the accumulated depreciation balance until each unit is retired. Nuclear decommissioning costs are recovered in rates. The Company is utilizing a 1995 site-specific study for Palo Verde, prepared for the Company by an independent consultant, that assumes the prompt removal/dismantlement method of decommissioning. The Company is required to update the study every three years. As required by regulation, the Company has established external trust accounts into which quarterly deposits are made for decommissioning. As of December 31, 1997 and 1996, the Company had deposited a total of $79.5 million and $68.1 million, respectively. The trust accounts are included in "Investments and Other Assets" on the Balance Sheets at a market value of $124.6 million and $95.5 million on December 31, 1997 and 1996, respectively. The trust funds are invested primarily in fixed-income securities and domestic stock and are classified as available for sale. Realized and unrealized gains and losses are reflected in accumulated depreciation. In February 1996, the FASB issued an exposure draft "Accounting for Certain Liabilities Related to Closure or Removal of Long-Lived Assets" which would require the estimated present value of the cost of decommissioning and certain other removal costs to be recorded as a liability, along with an offsetting plant asset when a decommissioning or other removal obligation is incurred. The FASB has not determined when a revised exposure draft or a final statement will be issued. 47 APS NOTES TO FINANCIAL STATEMENTS 14.

(b) Net loss for the fourth quarter of 1996 includes an after-tax charge of $18.9 million for a voluntary severance program. 48 APS NOTES TO FINANCIAL STATEMENTS 15. Stock Options Pinnacle West, the Company's parent, has incentive plans under which it may grant non-qualified stock options (NQSOs), incentive stock options (ISOs) and restricted stock awards to Pinnacle West and APS officers and key employees. The plans provide for the granting of new options or awards of up to 3.5 million shares at a price per option not less than fair market value on the date the option is granted. The plans also provide for the granting of any combination of stock appreciation rights or dividend equivalents. The awards outstanding under the various incentive plans at December 31, 1997 approximate 1,486,417 NQSOs, 183,190 restricted shares, and no dividend equivalent shares, ISOs or stock appreciation rights. The FASB issued SFAS No. 123 "Accounting for Stock-Based Compensation" which was effective for 1996. The statement encourages, but does not require, companies to recognize compensation expense based on the fair value method. The Company continues to recognize expense based on Accounting Principles Board Opinion No. 25. Had the Company determined compensation expense based on the fair value method, the Company's net income would have been reduced to the pro forma amounts indicated below: 1997 1996 1995 -------- -------- -------- (Thousands of Dollars) Net income As reported ............ $251,493 $243,471 $239,570 Pro forma .............. $251,142 $243,291 $239,547 The fair value of each fixed stock option is estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions: 1997 1996 1995 ------ ------ ------ Risk-free interest rate ....... 5.66% 5.77% 5.43% Dividend growth ............... 4.50% 4.50% 4.50% Volatility .................... 15.63% 17.10% 12.60% Expected life (months) ........ 60 58 56 The effects of applying SFAS No. 123 for disclosing compensation cost may not be representative of the effects on reported net income for future years because pro forma net income does not consider compensation costs for stock options granted prior to January 1, 1995. 49 ITEM 9.
