NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

1. The condensed consolidated financial statements include the accounts of Pinnacle West and our subsidiaries: APS, Pinnacle West Energy, APS Energy Services, SunCor and El Dorado (principally NAC). All significant intercompany accounts and transactions between the consolidated companies have been eliminated. We have reclassified certain prior year amounts to conform to the current year presentation (see Notes 10 and 19).

2. Our unaudited condensed consolidated financial statements reflect all adjustments which we believe are necessary for the fair presentation of our financial position and results of operations for the periods presented. These adjustments are of a normal recurring nature with the exception of the cumulative effects of changes in accounting for derivatives and trading activities (see Note 10), the transition adjustment for asset retirement obligations (see Note 13) and real estate discontinued operations (see Note 19). We suggest that these condensed consolidated financial statements and notes to condensed consolidated financial statements be read along with the consolidated financial statements and notes to consolidated financial statements included in our 2002 10-K.

3. Weather conditions cause significant seasonal fluctuations in our revenues. In addition, trading and wholesale marketing activities can have significant impacts on our results for interim periods. Consequently, results for interim periods do not necessarily represent results to be expected for the year.

4. On April 7, 2003, APS redeemed approximately $33 million of its First Mortgage Bonds, 8% Series due 2025, and on August 1, 2003, APS redeemed approximately $54 million of its First Mortgage Bonds, 7.25% Series due 2023.

On May 12, 2003, APS issued $500 million of debt as follows: $300 million aggregate principal amount of its 4.650% Notes due 2015 and $200 million aggregate principal amount of its 5.625% Notes due 2033. Also on May 12, 2003, APS made a $500 million loan to Pinnacle West Energy, and Pinnacle West Energy distributed the net proceeds of that loan to us to fund our repayment of a portion of the debt incurred to finance the construction of the PWEC Dedicated Assets. See “ACC Financing Orders” in Note 5 for additional information. With Pinnacle West Energy’s distribution to us, on May 12, 2003, we repaid the outstanding balance ($167 million) under a credit facility. We used a portion of the remaining proceeds to redeem our $250 million Floating Rate Notes due 2003 on June 2, 2003 and to repay other short-term debt.

5. Regulatory Matters

State

Overview

On September 21, 1999, the ACC approved Rules that provide a framework for the introduction of retail electric competition in Arizona. On September 23, 1999, the ACC approved a comprehensive settlement agreement among APS and various parties related

to the implementation of retail electric competition in Arizona. On September 10, 2002, the ACC issued the Track A Order, which, among other things, directed APS not to transfer its generation assets to Pinnacle West Energy, as previously required under the Rules and the 1999 Settlement Agreement. See “Track A Order” below. The Track A Order and legal challenges to the Rules have raised considerable uncertainty about the status and pace of retail electric competition and of electric restructuring in Arizona.

On March 14, 2003, the ACC issued the Track B Order, which required APS to solicit bids for certain estimated amounts of capacity and energy for periods beginning July 1, 2003. Pinnacle West Energy bid on and entered into a contract to supply most of APS’ requirements in the summer months through September 2006. See “Track B Order” below.

On April 4, 2003, the ACC issued the Financing Order authorizing APS to lend up to $500 million to Pinnacle West Energy. See “ACC Financing Orders” below. On May 12, 2003, APS issued $500 million of debt pursuant to the Financing Order and made a $500 million loan to Pinnacle West Energy. Pinnacle West Energy distributed the net proceeds of that loan to us to fund the repayment of a portion of the debt we incurred to finance the construction of the PWEC Dedicated Assets. See Note 4.

On June 27, 2003, APS filed a general rate case with the ACC and requested a $175.1 million, or 9.8%, increase in its annual retail electricity revenues, to become effective July 1, 2004. The major components of the request are described under “APS General Rate Case and Retail Rate Adjustment Mechanisms” below.

1999 Settlement Agreement

The following are the major provisions of the 1999 Settlement Agreement, as approved by the ACC:

• APS has reduced rates for standard-offer service for customers with loads less than three MW in a series of annual retail electricity price reductions of 1.5% on July 1 for each of the years 1999 to 2003 for a total of 7.5%. Based on the price reductions authorized in the 1999 Settlement Agreement, there were retail price decreases of approximately $24 million ($14 million after taxes), effective July 1, 1999; approximately $28 million ($17 million after taxes), effective July 1, 2000; approximately $27 million ($16 million after taxes), effective July 1, 2001; approximately $28 million ($17 million after taxes), effective July 1, 2002; and approximately $29 million ($18 million after taxes), effective July 1, 2003. For customers having loads of three MW or greater, standard-offer rates have been reduced in varying annual increments that total 5% in the years 1999 through 2002.

• Unbundled rates being charged by APS for competitive direct access service (for example, distribution services) became effective upon approval of the 1999 Settlement Agreement, retroactive to July 1, 1999, and also became subject to annual reductions beginning January 1, 2000, that vary by rate class, through January 1, 2004.

• There is a moratorium on retail price changes for standard-offer and unbundled competitive direct access services until July 1, 2004, except for the price reductions described above and certain other limited circumstances. Neither the ACC nor APS is prevented from seeking or authorizing rate changes prior to July 1, 2004 in the event of conditions or circumstances that constitute an emergency, such as an inability to finance on reasonable terms; material changes in APS’ cost of service for ACC-regulated services resulting from federal, tribal, state or local laws; regulatory requirements; or judicial decisions, actions or orders.

• APS will be permitted to defer for later recovery prudent and reasonable costs of complying with the Rules, system benefits costs in excess of the levels included in then-current (1999) rates, and costs associated with the “provider of last resort” and standard-offer obligations for service after July 1, 2004. These costs are to be recovered through an adjustment clause or clauses commencing on July 1, 2004. See “APS General Rate Case and Retail Rate Adjustment Mechanisms” below.

• APS’ distribution system opened for retail access effective September 24, 1999. Customers were eligible for retail access in accordance with the phase-in adopted by the ACC under the Rules (see “Retail Electric Competition Rules” below), including an additional 140 MW being made available to eligible non-residential customers. APS opened its distribution system to retail access for all customers on January 1, 2001. The regulatory developments and legal challenges to the Rules discussed in this Note have raised considerable uncertainty about the status and pace of electric competition and of electric restructuring in Arizona. Although some very limited retail competition existed in APS’ service area in 1999 and 2000, there are currently no active retail competitors providing unbundled energy or other utility services to APS’ customers. As a result, we cannot predict when, and the extent to which, additional competitors will re-enter APS’ service territory.

• Prior to the 1999 Settlement Agreement, APS was recovering substantially all of its regulatory assets through July 1, 2004, pursuant to a 1996 regulatory agreement. In addition, the 1999 Settlement Agreement states that APS has demonstrated that its allowable stranded costs, after mitigation and exclusive of regulatory assets, are at least $533 million net present value (in 1999 dollars). The 1999 Settlement Agreement also stated that APS will not be allowed to recover $183 million net present value (in 1999 dollars) of the $533 million. The 1999 Settlement Agreement provides that APS will have the opportunity to recover $350 million net present value (in 1999 dollars) through a competitive transition charge that will remain in effect through December 31, 2004, at which time it will terminate. The costs subject to recovery under the adjustment clause described above will be decreased or increased by any over/under-recovery of the $350 million due to sales volume variances. As discussed below under “APS General Rate Case and Retail Rate Adjustment Mechanisms,” APS is seeking to recover amounts written off by APS as a result of the 1999 Settlement Agreement.

• The 1999 Settlement Agreement required APS to form, or cause to be formed, a separate corporate affiliate or affiliates and transfer to such affiliate(s) its competitive electric assets and services no later than December 31, 2002. The 1999 Settlement Agreement provided that APS would be allowed to defer and later collect, beginning July 1, 2004, 67% of its costs to accomplish the required transfer of generation assets to an affiliate. However, as noted above and discussed in greater detail below, in 2002 the ACC unilaterally modified this aspect of the 1999 Settlement Agreement by issuing an order preventing APS from transferring its generation assets. APS is seeking to recover all costs incurred by APS in preparation for the previously anticipated transfer of generation assets to Pinnacle West Energy. See “APS General Rate Case and Retail Rate Adjustment Mechanisms” below.

Retail Electric Competition Rules

The Rules approved by the ACC included the following major provisions:

• They apply to virtually all Arizona electric utilities regulated by the ACC, including APS.

• Effective January 1, 2001, retail access became available to all APS retail electricity customers.

• Electric service providers that get CC&N’s from the ACC can supply only competitive services, including electric generation, but not electric transmission and distribution.

• Affected utilities must file ACC tariffs that unbundle rates for noncompetitive services.

• The ACC shall allow a reasonable opportunity for recovery of unmitigated stranded costs.

• Absent an ACC waiver, prior to January 1, 2001, each affected utility (except certain electric cooperatives) must transfer all competitive electric assets and services to an unaffiliated party or parties or to a separate corporate affiliate or affiliates. Under the 1999 Settlement Agreement, APS received a waiver to allow transfer of its competitive electric assets and services to affiliates no later than December 31, 2002. However, as noted above and discussed in greater detail below, in 2002 the ACC reversed its decision, as reflected in the Rules, to require APS to transfer its generation assets.

Under the 1999 Settlement Agreement, the Rules are to be interpreted and applied, to the greatest extent possible, in a manner consistent with the 1999 Settlement Agreement. If the two cannot be reconciled, APS must seek, and the other parties to the 1999

Settlement Agreement must support, a waiver of the Rules in favor of the 1999 Settlement Agreement.

On November 27, 2000, a Maricopa County, Arizona, Superior Court judge issued a final judgment holding that the Rules are unconstitutional and unlawful in their entirety due to failure to establish a fair value rate base for competitive electric service providers and because certain of the Rules were not submitted to the Arizona Attorney General for certification. The judgment also invalidates all ACC orders authorizing competitive electric service providers, including APS Energy Services, to operate in Arizona. We do not believe the ruling affects the 1999 Settlement Agreement. The 1999 Settlement Agreement was not at issue in the consolidated cases before the judge. Further, the ACC made findings related to the fair value of APS’ property in the order approving the 1999 Settlement Agreement. The ACC and other parties aligned with the ACC have appealed the ruling to the Arizona Court of Appeals, as a result of which the Superior Court’s ruling is automatically stayed pending further judicial review. That appeal is still pending. In a similar appeal concerning the issuance of competitive telecommunications CC&N’s, the Arizona Court of Appeals invalidated rates for competitive carriers due to the ACC’s failure to establish a fair value rate base for such carriers. The Arizona Supreme Court agreed that the ACC had to determine a fair value rate base but vacated the Court of Appeals’ requirement that competitive rates be set based only on such fair value rate base.

Provider of Last Resort Obligation

Although the Rules allow retail customers to have access to competitive providers of energy and energy services, APS is the “provider of last resort” for standard-offer, full-service customers under rates that have been approved by the ACC. These rates are established until at least July 1, 2004. The 1999 Settlement Agreement allows APS to seek adjustment of these rates in the event of emergency conditions or circumstances, such as the inability to secure financing on reasonable terms; material changes in APS’ cost of service for ACC-regulated services resulting from federal, tribal, state or local laws; regulatory requirements; or judicial decisions, actions or orders. Energy prices in the western wholesale market vary and, during the course of the last two years, have been volatile. At various times, prices in the spot wholesale market have significantly exceeded the amount included in APS’ current retail rates. In the event of shortfalls due to unforeseen increases in load demand or generation or transmission outages, APS may need to purchase additional supplemental power in the wholesale spot market. Unless APS is able to obtain an adjustment of its rates under the emergency provisions of the 1999 Settlement Agreement, there can be no assurance that APS would be able to fully recover the costs of this power. See “APS General Rate Case and Retail Rate Adjustment Mechanisms” below for a discussion of retail rate adjustment mechanisms that were the subject of ACC hearings in April 2003.

Track A Order

On September 10, 2002, the ACC issued the Track A Order, in which the ACC, among other things:

• reversed its decision, as reflected in the Rules, to require APS to transfer its generation assets either to an unrelated third party or to a separate corporate affiliate; and

• unilaterally modified the 1999 Settlement Agreement, which authorized APS’ transfer of its generating assets, and directed APS to cancel its activities to transfer its generation assets to Pinnacle West Energy.

On November 15, 2002, APS filed appeals of the Track A Order in the Maricopa County, Arizona Superior Court and in the Arizona Court of Appeals. Arizona Public Service Company vs. Arizona Corporation Commission, CV 2002-0222 32. Arizona Public Service Company vs. Arizona Corporation Commission, 1CA CC 02-0002. On December 13, 2002, APS and the ACC Staff agreed to principles for resolving certain issues raised by APS in its appeals of the Track A Order. APS and the ACC are the only parties to the Track A Order appeals. The major provisions of the principles include, among other things, the following:

• APS and the ACC Staff agreed that it would be appropriate for the ACC to consider the following matters in APS’ general rate case, which was filed on June 27, 2003:

• the generating assets to be included in APS’ rate base, including the question of whether the PWEC Dedicated Assets should be included in APS’ rate base;

• the appropriate treatment of the $234 million pretax asset write-off agreed to by APS as part of the 1999 Settlement Agreement; and

• the appropriate treatment of costs incurred by APS in preparation for the previously anticipated transfer of generation assets to Pinnacle West Energy.

• Upon the ACC’s issuance of a final decision that is no longer subject to appeal approving APS’ request to provide $500 million of financing or credit support to Pinnacle West Energy or the Company, with appropriate conditions, APS’ appeals of the Track A Order would be limited to the issues described in the preceding bullet points, each of which would be presented to the ACC for consideration prior to any final judicial resolution. As noted below, the ACC issued the Financing Order on April 4, 2003. The Financing Order is final and no longer subject to appeal. As a result, APS’ appeals of the Track A Order will be limited to the issues described in the preceding bullet points.

On February 21, 2003, a Notice of Claim was filed with the ACC and the Arizona Attorney General on behalf of APS, Pinnacle West and Pinnacle West Energy to preserve their and our rights relating to the Track A Order. As of April 22, 2003, the Notice of Claim was deemed denied with respect to the ACC and the Arizona Attorney General, and APS, Pinnacle West and Pinnacle West Energy may now pursue the claim in court.

Track B Order

On March 14, 2003, the ACC issued the Track B Order, which required APS to solicit bids for certain estimated amounts of capacity and energy for periods beginning July 1, 2003. For 2003, APS was required to solicit competitive bids for about 2,500 MW of capacity and about 4,600 gigawatt-hours of energy, or approximately 20% of APS’ total retail energy requirements. The bid amounts were expected to increase in 2004 and 2005 based largely on growth in APS’ retail load and APS’ retail energy sales. The Track B Order also confirmed that it was “not intended to change the current rate base status of [APS’] existing assets.”

The order recognizes APS’ right to reject any bids that are unreasonable, uneconomical or unreliable. The ACC Staff and an independent monitor participated in the Track B procurement process. The Track B Order also contains requirements relating to standards of conduct between APS and any affiliate of APS participating in the competitive solicitation, requires that APS treat bidders in a non-discriminatory manner and requires APS to file a protocol regarding short-term and emergency procurements. The order permits the provision by APS of corporate oversight, support and governance as long as such activities do not favor Pinnacle West Energy in the procurement process or provide Pinnacle West Energy with confidential APS bidding information that is not available to other bidders. The order directs APS to evaluate bids on cost, reliability and reasonableness. The decision requires bidders to allow the ACC to inspect their plants and requires assurances of appropriate competitive market conduct from senior officers of such bidders. Following the solicitation, the decision requires APS to prepare a report evaluating environmental issues relating to the procurement and a series of workshops on environmental risk management will be commenced thereafter.

APS issued requests for proposals in March 2003 and by May 6, 2003, APS entered into contracts to meet all or a portion of its requirements for the years 2003 through 2006 as follows:

(1) Pinnacle West Energy agreed to provide 1,700 MW in July through September of 2003 and in June through September of 2004, 2005 and 2006, by means of a unit contingent contract.

(2) PPL EnergyPlus, LLC agreed to provide 112 MW in July through September of 2003 and 150 MW in June through September of 2004 and 2005, by means of a unit contingent contract.

(3) Panda Gila River LP agreed to provide 450 MW in October of 2003 and 2004 and May of 2004 and 2005, and 225 MW from November 2003 through April 2004 and from November 2004 through April 2005, by means of firm call options.

ACC Financing Orders

On April 4, 2003, the ACC issued the Financing Order authorizing APS to lend up to $500 million to Pinnacle West Energy, guarantee up to $500 million of Pinnacle West

Energy debt, or a combination of both, not to exceed $500 million in the aggregate (the “APS Loan”), subject to the following principal conditions:

• any debt issued by APS pursuant to the order must be unsecured;

• the APS Loan must be callable and secured by the PWEC Dedicated Assets;

• the APS Loan must bear interest at a rate equal to 264 basis points above the interest rate on APS debt that could be issued and sold on equivalent terms (including, but not limited to, maturity and security);

• the 264 basis points referred to in the previous bullet point will be capitalized as a deferred credit and used to offset retail rates in the future, with the deferred credit balance bearing an interest rate of six percent per annum;

• the APS Loan must have a maturity date of not more than four years, unless otherwise ordered by the ACC;

• any demonstrable increase in APS’ cost of capital as a result of the transaction (such as from a decline in bond rating) will be excluded from future rate cases;

• APS must maintain a common equity ratio of at least forty percent and may not pay common dividends if such payment would reduce its common equity ratio below that threshold, unless otherwise waived by the ACC. The ACC will process any waiver request within sixty days, and for this sixty-day period this condition will be suspended. However, this condition, which will continue indefinitely, will not be permanently waived without an order of the ACC; and

• certain waivers of the ACC’s affiliated interest rules previously granted to APS and its affiliates will be temporarily withdrawn and, during the term of the APS Loan, neither Pinnacle West nor Pinnacle West Energy may reorganize or restructure, acquire or divest assets, or form, buy or sell affiliates (each, a “Covered Transaction”), or pledge or otherwise encumber the Pinnacle West Energy assets without prior ACC approval, except that the foregoing restrictions will not apply to the following categories of Covered Transactions:

• Covered Transactions less than $100 million, measured on a cumulative basis over the calendar year in which the Covered Transactions are made;

• Covered Transactions by SunCor of less than $300 million through 2005, consistent with SunCor’s anticipated accelerated asset sales activity during those years;

• Covered Transactions related to the payment of ongoing construction costs for Pinnacle West Energy’s (a) West Phoenix Unit 5, located in

Phoenix, and (b) Silverhawk plant, located near Las Vegas, with an expected commercial operation date in mid-2004; and

• Covered Transactions related to the sale of 25% of the Silverhawk plant to SNWA if SNWA exercises its existing purchase option to do so.

The ACC also ordered the ACC Staff to conduct an inquiry into our and our affiliates’ compliance with the retail electric competition and related rules and decisions. On June 13, 2003, APS submitted its report on these matters to the ACC Staff.

On May 12, 2003, APS issued $500 million of debt pursuant to the Financing Order and made a $500 million loan to Pinnacle West Energy. Pinnacle West Energy distributed the net proceeds of that loan to us to fund the repayment of a portion of the debt we incurred to finance the construction of the PWEC Dedicated Assets. See Note 4.

On November 22, 2002, the ACC issued an order (the “Interim Financing Order”) approving APS’ request to permit APS to (a) make short-term advances to Pinnacle West in the form of an inter-affiliate line of credit in the amount of $125 million, or (b) guarantee $125 million of Pinnacle West’s short-term debt, subject to certain conditions. As of June 30, 2003, there were no borrowings outstanding under this financing arrangement.

APS General Rate Case and Retail Rate Adjustment Mechanisms

As noted above, on June 27, 2003, APS filed a general rate case with the ACC and requested a $175.1 million, or 9.8%, increase in its annual retail electricity revenues, to become effective July 1, 2004. In this rate case, APS updated its cost of service and rate design.

Major Components of the Request The major reasons for the request include:

• complying with the provisions of the 1999 Settlement Agreement;

• incorporating significant increases in fuel and purchased power costs, including results of purchases through the ACC’s Track B procurement process;

• recognizing changes in APS’ cost of service, cost allocation and rate design;

• obtaining rate recognition of the PWEC Dedicated Assets;

• recovering $234 million written off by APS as a result of the 1999 Settlement Agreement; and

• recovering restructuring and compliance costs associated with the ACC’s Rules.

Requested Rate Increase The requested rate increase totals $175.1 million, or 9.8%, and is comprised of the following items (dollars in millions):

	Annual Revenue		Percent

Increase in base rates	$	166.8	9.3	%
Competition rules compliance charge	8.3		0.5	%
Total increase	$	175.1	9.8	%

Test Year The filing is based on an adjusted historical test year ended December 31, 2002.

Cost of Capital The proposed weighted average cost of capital for the test year ended December 31, 2002 is 8.67%, including an 11.5% return on equity.

Rate Base The request is based on a rate base of $4.2 billion, calculated using Original Cost Less Depreciation (“OCLD”) methodology. The OCLD rate base approximates the ACC-jurisdictional portion of the net book value of utility plant, net of accumulated depreciation and deferred taxes, as of December 31, 2002, except as set forth below.

The requested rate base includes the PWEC Dedicated Assets, with a total combined capacity of approximately 1,800 MW. These assets were included at their estimated July 1, 2004 net book value. Upon approval of the request, the PWEC Dedicated Assets would be transferred to APS from Pinnacle West Energy.

The filing also includes calculated amounts for Fair Value Rate Base and Replacement Cost New Depreciated (“RCND”) rate base. The ACC is required by the Arizona Constitution to make a finding of Fair Value Rate Base, which is defined as the arithmetic average of OCLD rate base and RCND rate base.

Recovery of Previous $234 Million Write-Off The request includes recovery, over a fifteen year period, of the write-off of $234 million pretax of regulatory assets by APS as a result of the 1999 Settlement Agreement. See “1999 Settlement Agreement” above.

Estimated Timeline APS has asked the ACC to approve the requested rate increase by July 1, 2004. The Company expects the ACC to issue procedural schedules during the next several months detailing the timeline for addressing the request.

The general rate case also addresses the implementation of rate adjustment mechanisms that were the subject of ACC hearings in April 2003. The rate adjustment mechanisms, which were authorized as a result of the 1999 Settlement Agreement, would allow APS to recover several types of costs, the most significant of which are power supply costs (fuel and purchased power costs) and costs associated with complying with the Rules. We assume that the ACC will make a decision in this general rate case by the end of 2004.

Federal

In July 2002, the FERC adopted a price mitigation plan that constrains the price of electricity in the wholesale spot electricity market in the western United States. The FERC adopted a price cap of $250 per MWh for the period subsequent to October 31, 2002. Sales at prices above the cap must be justified and are subject to potential refund.

On July 31, 2002, the FERC issued a Notice of Proposed Rulemaking for Standard Market Design for wholesale electric markets. Voluminous comments and reply comments were filed on virtually every aspect of the proposed rule. On April 28, 2003, the FERC Staff issued an additional white paper on the proposed Standard Market Design. The white paper discusses several policy changes to the proposed Standard Market Design, including a greater emphasis on flexibility for regional needs. The FERC invited comments on the white paper, but has not yet set a due date for filing comments. We are reviewing the proposed rulemaking and cannot currently predict what, if any, impact there may be to the Company if the FERC adopts the proposed rule or any modifications proposed in the comments.

General

The regulatory developments and legal challenges to the Rules discussed in this Note have raised considerable uncertainty about the status and pace of retail electric competition and of electric restructuring in Arizona. Although some very limited retail competition existed in APS’ service area in 1999 and 2000, there are currently no active retail competitors providing unbundled energy or other utility services to APS’ customers. As a result, we cannot predict when, and the extent to which, additional competitors will re-enter APS’ service territory. As competition in the electric industry continues to evolve, we will continue to evaluate strategies and alternatives that will position us to compete in the new regulatory environment.

6. Nuclear Insurance

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 $300 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, APS could be assessed retrospective premium adjustments. The maximum assessment per reactor under the program for each nuclear incident is approximately $101 million, subject to an annual limit of $10 million per incident. Based on APS’ interest in the three Palo Verde units, APS’ maximum potential assessment per incident for all three units is approximately $88 million, with an annual payment limitation of approximately $9 million.

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. APS 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.

7. Business Segments

We have three principal business segments (determined by products, services and the regulatory environment):

• our regulated electricity segment, which consists of regulated traditional retail and wholesale electricity businesses and related activities, and includes electricity generation, transmission and distribution;

• our marketing and trading segment, which consists of our competitive energy business activities, including wholesale marketing and trading and APS Energy Services’ commodity-related energy services. In early 2003, we moved our marketing and trading division from Pinnacle West to APS for future marketing and trading activities (existing wholesale contracts remain at Pinnacle West) as a result of the ACC’s Track A Order prohibiting the previously required transfer of APS’ generating assets to Pinnacle West Energy; and

• our real estate segment, which consists of SunCor’s real estate development and investment activities.

The amounts in our other segment include activity principally related to NAC in the periods ended June 30, 2003 (see Note 12), as well as the parent company and other subsidiaries. Financial data for the Company’s business segments follows (dollars in millions):

	Three Months Ended June 30,					Six Months Ended June 30,					Twelve Months Ended June 30,

(a) In the twelve months ended June 30, 2003, we recorded a $66 million after tax charge as of October 1, 2002 for the cumulative effect of a change in accounting for trading activities, for the early adoption of EITF 02-3, “Issues Involved in Accounting for Derivative Contracts Held for Trading Purposes and Contracts Involved in Energy Trading and Risk Management Activities.” In the twelve months ended June 30, 2002, APS recorded a $12 million after tax charge in July 2001 for the cumulative effect of a change in accounting for derivatives as required by SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities.”

(b) Includes income from discontinued operations for the three months ended June 30 of $1 million (after tax) in 2003 and $6 million (after tax) in 2002. Includes income from discontinued operations for the six months ended June 30 of $6 million (after tax) in 2003 and $7 million (after tax) in 2002. Includes income from discontinued operations for the twelve months ended June 30 of $8 million (after tax) in 2003 and $7 million (after tax) in 2002. See Note 19 for further discussion of our real estate activities.

8. Accounting Matters

In April 2003, the FASB issued SFAS No. 149, “Amendment of Statement 133 on Derivative Instruments and Hedging Activities.” This statement amends and clarifies financial accounting and reporting for derivative instruments and for hedging activities under SFAS No. 133. The provisions of SFAS No. 149 that relate to previously issued SFAS No. 133 derivatives implementation guidance should continue to be applied in accordance with the effective dates of the original implementation guidance. In general, other provisions are applied prospectively to contracts entered into or modified after June 30, 2003, and for hedging relationships designated after June 30, 2003. We are currently evaluating the impacts of SFAS No. 149 on our financial statements.

In June 2003, the FASB’s Derivatives Implementation Group (DIG) issued DIG Issue C20, “Scope Exceptions: Interpretation of the Meaning of ‘Not Clearly and Closely Related’ in Paragraph 10(b) regarding Contracts with a Price Adjustment Feature.” To qualify for a normal purchases and sales scope exception under SFAS No. 133 the pricing in a contract must be clearly and closely related to the item being purchased or sold. DIG Issue C20 provides guidance on the clearly and closely related criterion and supercedes previous guidance. The new rules allow the use of broad-based market indicators in certain circumstances.

DIG Issue C20 is effective for us on October 1, 2003. It is to be applied prospectively to existing and future contracts. A special transition adjustment is required for an entity that had been applying the normal scope exception to a derivative contract that contained a price adjustment feature that was not based on the fair value of the item being purchased or sold or was not an ingredient or direct factor in its production. That entity should record a cumulative effect adjustment to net income for the fair value of the contract at the implementation date of DIG Issue C20. While we continue to evaluate this new guidance, we currently do not expect DIG Issue C20 to have a material impact on our financial statements.

In May 2003, the FASB ratified EITF 01-8, “Determining Whether an Arrangement Contains a Lease.” This issue provides guidance for determining whether an arrangement contains a lease that is within the scope of SFAS No. 13, “Accounting for Leases.” Under EITF 01-8, an arrangement contains a lease if the specific property, plant or equipment has been explicitly or implicitly identified and the arrangement conveys to the purchaser the right to use the property, plant or equipment as defined in this issue. For us, the new guidance is effective for arrangements committed to or modified after June 30, 2003. We currently do not expect EITF 01-8 to have a material impact on our financial statements.

In May 2003, the FASB issued SFAS No. 150, “Accounting for Certain Financial Instruments with Characteristics of Both Liabilities and Equity.” This statement requires that an issuer classify certain financial instruments, which were previously classified as equity, as liabilities (or assets in some circumstances). This statement was effective immediately for financial instruments entered into or modified after May 31, 2003 and otherwise is effective for all other financial instruments beginning July 1, 2003. While we continue to evaluate this new guidance, we currently do not expect SFAS No. 150 to have a material impact on our financial statements.

In November 2002, the EITF reached a consensus on EITF 00-21, “Revenue Arrangements with Multiple Deliverables.” EITF 00-21 addresses certain aspects of the accounting by a vendor for arrangements under which it will perform multiple revenue-generating activities. EITF 00-21 specifically addresses how to determine whether an arrangement has identifiable, separable revenue-generating activities. EITF 00-21 does not address when the criteria for revenue recognition are met or provide guidance on the appropriate revenue recognition convention. For us, EITF 00-21 is effective for revenue arrangements entered into after June 30, 2003. We currently do not expect EITF 00-21 to have a material impact on our financial statements.

In 2001, the American Institute of Certified Public Accountants (AICPA) issued an exposure draft of a proposed Statement of Position (SOP), “Accounting for Certain Costs Related to Property, Plant, and Equipment.” This proposed SOP would create a project timeline framework for capitalizing costs related to property, plant and equipment construction. It would require that property, plant and equipment assets be accounted for at the component level and require administrative and general costs incurred in support of capital projects to be expensed in the current period. We are waiting for further guidance from the FASB and the AICPA on the timing of the final guidance.

See the following Notes for other new accounting standards:

• Note 9 for a new interpretation (FIN No. 46) related to VIEs;

• Note 10 for a new EITF issue (EITF 02-3) related to accounting for energy trading contracts;

• Note 13 for a new accounting standard (SFAS No. 143) on asset retirement obligations;

• Note 15 for a new accounting standard (SFAS No. 148) on stock-based compensation; and

• Note 17 for a new interpretation (FIN No. 45) on guarantees.

9. Variable Interest Entities

In January 2003, the FASB issued FIN No. 46, “Consolidation of Variable Interest Entities.” FIN No. 46 requires that we consolidate a VIE if we have a majority of the risk of loss from the VIE’s activities or we are entitled to receive a majority of the VIE’s residual returns or both. A VIE is a corporation, partnership, trust or any other legal structure that either does not have equity investors with voting rights or has equity investors that do not provide sufficient financial resources for the entity to support its activities. FIN No. 46 is effective immediately for any VIE created after January 31, 2003 and is effective July 1, 2003 for VIEs created before February 1, 2003. We currently do not expect FIN No. 46 to have a material impact on our financial statements.

In 1986, APS entered into agreements with three separate SPE lessors in order to sell and lease back interests in Palo Verde Unit 2. The leases are accounted for as operating leases in accordance with GAAP. While we continue to evaluate the guidance, we currently do not expect that we will be required to consolidate the Palo Verde SPEs under FIN No. 46.

APS is exposed to losses under the Palo Verde sale-leaseback agreements upon the occurrence of certain events that APS does not consider to be reasonably likely to occur. Under certain circumstances (for example, the NRC issuing specified violation orders with respect to Palo Verde or the occurrence of specified nuclear events), APS would be required to assume the debt associated with the transactions, make specified payments to the equity participants, and take title to the leased Unit 2 interests, which, if appropriate, may be required to be written down in value. If such an event had occurred as of June 30, 2003, APS would have been required to assume approximately $268 million of debt and pay the equity participants approximately $200 million.

10. Derivative Instruments and Energy Trading Activities

changes in market value of such contracts have a high correlation to price changes in the hedged commodities. In addition, subject to specified risk parameters monitored by the ERMC, we engage in marketing and trading activities intended to profit from market price movements.

For the twelve months ended June 30, 2002, we recorded a $12 million after tax charge in net income and a $8 million after tax credit in common stock equity (as a component of other comprehensive income (loss)), both as cumulative effects of a change in accounting for derivatives, as required by SFAS No. 133. The charge primarily resulted from electricity option contracts. The credit resulted from unrealized gains on cash flow hedges.

We adopted the EITF 02-3 guidance for all contracts in the fourth quarter of 2002. In 2002, we recorded a $66 million after tax charge in net income as a cumulative effect adjustment for the previously recorded accumulated unrealized mark-to-market on energy trading contracts that did not meet the accounting definition of a derivative. Our energy trading contracts that are derivatives are accounted for at fair value under SFAS No. 133. Contracts that do not meet the definition of a derivative are accounted for on an accrual basis with the associated revenues and costs recorded at the time the contracted commodities are delivered or received. Additionally, all gains and losses (realized and unrealized) on energy trading contracts that qualify as derivatives are included in marketing and trading segment revenues on the Condensed Consolidated Statements of Income on a net basis. Derivative instruments used for non-trading activities are accounted for in accordance with SFAS No. 133.

EITF 02-3 requires that derivatives held for trading purposes, whether settled financially or physically, be reported in the income statement on a net basis. Conversely, all non-trading contracts and derivatives are to be reported gross on the income statement.

The mark-to-market related to our risk management and trading activities are presented in two categories, consistent with our business segments:

• System - non-trading derivative instruments that hedge our purchases and sales of electricity and fuel for APS’ Native Load requirements of our regulated electricity business segment; and

• Marketing and Trading - both non-trading and trading derivative instruments of our competitive business segment.

The changes in derivative fair value of our system positions included in the Condensed Consolidated Statements of Income for the three, six and twelve months ended June 30, 2003 and 2002 are comprised of the following (dollars in thousands):

	Three Months Ended June 30,						Six Months Ended June 30,					Twelve Months Ended June 30,
	2003			2002			2003		2002			2003			2002
Gains (losses) on the ineffective portion of derivatives qualifying for hedge accounting (a)	$	4,329		$	4,471		$	7,107	$	1,923		$	16,381		$	(263	)
Losses from the discontinuance of cash flow hedges	—			—			—		(45		)	(8,776		)	(1,870		)
Gains (losses) from non-hedge derivatives	948			(724		)	841		(1,579		)	(1,903		)	(954		)
Prior period mark-to-market losses (gains) realized upon delivery of commodities	(5,989		)	2,209			4,454		6,022			6,437			25,491
Total pretax gain (loss)	$	(712	)	$	5,956		$	12,402	$	6,321		$	12,139		$	22,404

(a) Time value component of options excluded from assessment of hedge effectiveness.

As of June 30, 2003, the maximum length of time over which we are hedging our exposure to the variability in future cash flows for forecasted transactions is approximately six years. During the twelve months ending June 30, 2004, we estimate that a net gain of $14 million before income taxes will be reclassified from accumulated other comprehensive loss as an offset to the effect on earnings of market price changes for the related hedged transactions.

The following table summarizes our assets and liabilities from risk management and trading activities at June 30, 2003 and December 31, 2002 (dollars in thousands):

Cash or collateral may be required to serve as collateral against our open positions on certain energy-related contracts. Collateral provided is $5 million at June 30, 2003 and at December 31, 2002 and is included in investments and other assets on the Condensed Consolidated Balance Sheet. Collateral held is $42 million at June 30, 2003 and $22 million at December 31, 2002 and is included in other liabilities on the Condensed Consolidated Balance Sheet.

11. Comprehensive Income

Components of comprehensive income for the three, six and twelve months ended June 30, 2003 and 2002, are as follows (dollars in thousands):

12. Commitments and Contingencies

California Energy Market Issues and Refunds in the Pacific Northwest

In July 2001, the FERC ordered an expedited fact-finding hearing to calculate refunds for spot market transactions in California during a specified time frame. This order calls for a hearing, with findings of fact due to the FERC after the CAISO and PX provide necessary historical data. The FERC directed an ALJ to make findings of fact with respect to: (1) the mitigated price in each hour of the refund period; (2) the amount of refunds owed by each supplier according to the methodology established in the order; and (3) the amount currently owed to each supplier (with separate quantities due from each entity) by the CAISO, the California Power Exchange, the investor-owned utilities and the State of California.

APS was a seller and a purchaser in the California markets at issue, and to the extent that refunds are ordered, APS should be a recipient as well as a payor of such amounts. On December 12, 2002, an ALJ issued Proposed Findings of Fact with respect to the refunds. On March 26, 2003, the FERC adopted the great majority of the proposed findings, revising only the calculation of natural gas prices for the final determination of mitigated prices in the California markets. Sellers who may actually have paid more for natural gas than the proxy prices adopted by the FERC are required to submit necessary data to the FERC, after which a technical conference will be held. Finalization of refund calculations is expected by the end of 2003. Subsequent to the foregoing refund decision by the FERC, the California parties filed a request for rehearing asking the FERC to expand the time period and transactions covered by the refund proceeding and provide for approximately $3 billion in additional refunds relating to sales by all sellers in the California markets. APS does not anticipate material changes in its exposure and still believes, subject to the finalization of the revised proxy prices, that it will be entitled to a net refund.

On November 20, 2002, the FERC reopened discovery in these proceedings pursuant to instructions of the United States Court of Appeals for the Ninth Circuit that the FERC permit parties to offer additional evidence of potential market manipulation for the period January 1, 2000 through June 20, 2001. Parties submitted additional evidence and proposed findings, which the FERC continues to consider. On a parallel track, in March 2003, FERC made public a final report on price manipulation in Western markets, prepared by its staff and covering spot markets in the West in 2000 and 2001. The report stated that a significant number of entities who participated in the California markets during the 2000 to 2001 time period, including APS, may potentially have been involved in arbitrage transactions that allegedly violated certain provisions of the CAISO tariff. The report also recommended that the FERC issue an order to show cause why these transactions did not violate the CAISO tariff with potential disgorgement of any unjust profits.

On June 25, 2003, the FERC issued an order finding that certain identified entities appear to have potentially participated in activities that constitute gaming and/or anomalous market behavior in violation of the CAISO’s and PX’s tariffs during the period of January 1, 2000 to June 20, 2001. The FERC directed the CAISO, within 21 days of the date of the order to provide the identified entities with all of the specific transaction data for each of the specified potential gaming practices, and directed the identified entities to file responses within 45 days thereafter, absent a settlement. The FERC also established a hearing proceeding to be held before an ALJ for the identified entities to show cause, why they should not be found to have engaged in gaming practices in violation of the CAISO and PX tariffs. APS was named as an identified entity in this order because of evidence of possible use of “paper trading” (the buy back of ancillary services) and “false import” (ricochet or megawatt laundering) strategies. The show cause submissions are due to the FERC on September 2, 2003. Based on its review of the allegations, as outlined in the terms of the order, APS believes that it was not improperly engaged in any of the identified gaming practices.

Also in June 2003, the FERC initiated an investigation of all bids in the CAISO and PX markets above $250 per MWh during the period May 1, 2000 through October 1, 2000. The FERC Office of Market Oversight and Investigations has issued data requests and is required to report back to the FERC by year-end 2003. Although APS bid over $250 per MWh during the time period in question, APS believes that its bids were not improper.

With regard to the Pacific Northwest, the FERC, in 2001, ordered an evidentiary proceeding to discuss and evaluate possible refunds. The FERC required that the record establish the volume of the transactions, the identification of the net sellers and net buyers, the price and terms and conditions of the sales contracts and the extent of potential refunds. On September 24, 2001, an ALJ concluded that prices in the Pacific Northwest during the period December 25, 2000 through June 20, 2001 were the result of a number of factors in addition to price signals from the California markets, including the shortage of supply, excess demand, drought and increased natural gas prices. Under these circumstances, the ALJ ultimately concluded that the prices in the Pacific Northwest were not unreasonable or unjust and refunds should not be ordered in this proceeding. On December 19, 2002, the FERC opened a new discovery period to permit the parties to offer additional evidence for the period January 1, 2000 through June 20, 2001. Additional evidence was submitted in March 2003. In June 2003, the FERC issued a final order terminating this proceeding without refunds. Certain parties have sought rehearing of the FERC’s final order.

Although the FERC has not calculated the specific refund amounts due in California, concluded newly established investigations of behavior in the Western markets, or ruled upon the requests for rehearing in the Pacific Northwest cases, we do not expect that the resolution of these issues will have a material adverse impact on our financial position, results of operations or liquidity.

SCE and PG&E have publicly disclosed that their liquidity has been materially and adversely affected because of, among other things, their inability to pass on to ratepayers the prices each has paid for energy and ancillary services procured through the PX and the CAISO. PG&E filed for bankruptcy protection in 2001.

We are closely monitoring developments in the California energy market and the potential impact of these developments on us and our subsidiaries. Based on our evaluations, we previously reserved $10 million before income taxes for our credit exposure related to the California energy situation, $5 million of which was recorded in the fourth quarter of 2000 and $5 million of which was recorded in the first quarter of 2001. Our evaluations took into consideration our range of exposure of approximately zero to $38 million before income taxes and review of likely recovery rates in bankruptcy situations.

In the second quarter of 2002, PG&E filed its Modified Second Amended Disclosure Statement and the CPUC filed its Alternative Plan of Reorganization. Both plans generally indicated that PG&E would, at the close of bankruptcy proceedings, be able to pay in full all outstanding, undisputed debts. As a result of these developments, the probable range of our total exposure is approximately zero to $27 million before income taxes, and our best estimate of the probable loss is now approximately $6 million before income taxes. Consequently, we reversed $4 million of the $10 million reserve in the second quarter of 2002. We cannot predict with certainty, however, the impact that any future resolution or attempted resolution, of the California energy market situation may have on us, our subsidiaries or the regional energy market in general.

California Energy Market Litigation On March 19, 2002, the State of California filed a complaint with the FERC alleging that wholesale sellers of power and energy, including the Company, failed to properly file rate information at the FERC in connection with sales to California from 2000 to the present. State of California v. British Columbia Power Exchange et al., Docket No. EL02-71-000. The complaint requests the FERC to require the wholesale sellers to refund any rates that are “found to exceed just and reasonable levels.” This complaint has been dismissed by the FERC and the State of California is now appealing the matter to the Ninth Circuit Court of Appeals. In addition, the State of California and others have filed various claims, which have now been consolidated, against several power suppliers to California alleging antitrust violations. Wholesale Electricity Antitrust Cases I and II, Superior Court in and for the County of San Diego, Proceedings Nos. 4204-00005 and 4204-00006. Two of the suppliers who were named as defendants in those matters, Reliant Energy Services, Inc. (and other Reliant entities) and Duke Energy and Trading, LLP (and other Duke entities), filed cross-claims against various other participants in the PX and CAISO markets, including APS, attempting to expand those matters to such other participants. APS has not yet filed a responsive pleading in the matter, but APS believes the claims by Reliant and Duke as they relate to APS are without merit.

APS was also named in a lawsuit regarding wholesale contracts in California. James Millar, et al. v. Allegheny Energy Supply, et al., United States District Court in and for the District of Northern California, Case No. C02-2855 EMC. The complaint alleges basically that the contracts entered into were the result of an unfair and unreasonable market. The PX has filed a lawsuit against the State of California regarding the seizure of forward contracts and the State has filed a cross complaint against APS and numerous other PX participants. Cal PX v. The State of California Superior Court in and for the County of Sacramento, JCCP No. 4203. Various preliminary motions are being filed and we cannot currently predict the outcome of this matter. The “United States Justice Foundation” is suing numerous wholesale energy contract suppliers to California, including us, as well as the California Department of Water Resources, based upon an alleged conflict of interest

arising from the activities of a consultant for Edison International who also negotiated long-term contracts for the California Department of Water Resources. McClintock, et al. v. Yudhraja, Superior Court in and for the County of Los Angeles, Case No. GC 029447. The California Attorney General has indicated that an investigation by his office did not find evidence of improper conduct by the consultant. We believe the claims against APS and us in the lawsuits mentioned in this paragraph are without merit and will have no material adverse impact on our financial position, results of operations or liquidity.

The Citizens Power Service Agreement

APS has a long history of contractual relations with Citizens relating to providing electricity and ancillary services to the utility in Arizona owned by Citizens. Under the current power sale agreement, we provide for deliveries of electricity and ancillary services through May 31, 2008. On August 11, 2003, Citizens sold its Arizona utility to a subsidiary of UniSource, UNS Electric, Inc. (“UNS Electric”). In connection with that sale, the above referenced power sale agreement was amended and assigned to UNS Electric. The Company does not expect any potential claims relating to the agreement and/or any prior related agreements, including as to any claims previously raised by Citizens, to have a material adverse impact on its financial statements.

El Dorado’s Investment in NAC

Through our unregulated wholly-owned subsidiary, El Dorado, we own a majority interest in NAC, a company that develops, markets and contracts for the manufacture of cask designs for spent nuclear fuel storage and transportation. Prior to the third quarter of 2002, our investment in NAC was accounted for under the equity method and our share of NAC’s earnings and losses was recorded in other income or expense in our Condensed Consolidated Statements of Income. Beginning in the third quarter of 2002, we fully consolidated NAC’s financial statements after acquiring a controlling interest in NAC as a result of increased voting representation on NAC’s Board of Directors. During the second and third quarters of 2002, we recorded cumulative losses of approximately $21 million before tax ($13 million after tax) related to NAC, primarily as a result of expected losses under contracts with two customers, including a contract between NAC and Maine Yankee Atomic Power Company (Maine Yankee).

On January 15, 2003, Maine Yankee notified NAC of its intention to terminate its contract with NAC. We recorded additional NAC losses of approximately $38 million before tax ($23 million after tax) in the fourth quarter of 2002, the substantial majority of which related to the termination of the Maine Yankee contract. As a result, in 2002, we recorded NAC losses of approximately $59 million before tax ($35 million after tax).

On March 4, 2003, Maine Yankee filed suit against Pinnacle West, NAC and a surety company in federal court in Portland, Maine. Maine Yankee Atomic Power Company v. United States Fire Insurance Company, Civil Action Docket No. 03-58-PC, United States District Court, District of Maine. The lawsuit and a related arbitration proceeding initiated by NAC were dismissed in April 2003 as part of a settlement among the parties. We reversed $5 million of loss reserves in the first quarter of 2003 related to NAC’s contract settlement. We believe we have reserved our exposure with respect to NAC’s contracts in all material respects and, as a result, we consider these charges non-recurring. We do not expect material losses for the year 2003 related to NAC.

Natural Gas Supply

APS and Pinnacle West Energy purchase the majority of their natural gas requirements for their gas-fired plants under contracts with a number of natural gas suppliers. APS’ and Pinnacle West Energy’s natural gas supply is transported pursuant to a firm, full requirements transportation service agreement with El Paso Natural Gas Company. The transportation agreement features a 10-year rate moratorium established in a comprehensive rate case settlement entered into in 1996.

On July 9, 2003 the FERC issued an order that alters the existing contractual obligations and the rights of parties to the 1996 settlement. Most importantly, the July 9 order requires the conversion of all firm, full requirements contracts to contract demand contracts effective September 1, 2003. This conversion will impact all full requirements contract holders by placing additional limitations on their ability to nominate firm transportation capacity. In order for APS to meet its natural gas supply and capacity requirements, APS must make market purchases, which APS expects to increase costs by approximately $5 million per year for natural gas supply and by approximately $14 million per year for capacity, both of which amounts are reflected in the Company’s budgets. APS and Pinnacle West Energy have sought appellate review of the FERC's July 9 order, on the grounds that the FERC decision to abrogate the full requirements contracts is arbitrary and capricious and is not supported by substantial evidence. Arizona Public Service Company and Pinnacle West Energy Corporation v. Federal Energy Regulatory Commission, United States Court of Appeals for the District of Columbia Circuit, No. 03-1206. This petition for review was consolidated with a petition filed by the ACC and other full requirements contract holders. We are continuing to analyze the market to determine the most favorable source and method of meeting our natural gas requirements.

13. Asset Retirement Obligations

On January 1, 2003, we adopted SFAS No. 143, “Accounting for Asset Retirement Obligations.” SFAS No. 143 provides accounting requirements for the recognition and measurement of liabilities associated with the retirement of tangible long-lived assets. The standard requires that these liabilities be recognized at fair value as incurred and capitalized as part of the related tangible long-lived assets. Accretion of the liability due to the passage of time is an operating expense and the capitalized cost is depreciated over the useful life of the long-lived asset. Prior to January 1, 2003 we accrued asset retirement obligations over the life of the related asset through depreciation expense.

APS has asset retirement obligations for its Palo Verde nuclear facilities and certain other generation, transmission and distribution assets. The Palo Verde asset retirement obligation primarily relates to final plant decommissioning. This obligation is based on the NRC’s requirements for disposal of radiated property or plant and agreements APS reached with the ACC for final decommissioning of the plant. The non-nuclear generation asset retirement obligations primarily relate to requirements for removing portions of those plants at the end of the plant life or lease term. Some of APS' transmission and distribution assets have asset retirement obligations because they are subject to right of way and easement agreements that require final removal. These agreements have a history of uninterrupted renewal that APS expects will continue for the foreseeable future. As a result, APS cannot

reasonably estimate the fair value of the asset retirement obligation related to such distribution and transmission assets. The asset retirement obligations associated with our non-regulated assets are immaterial.

On January 1, 2003, APS recorded a liability of $219 million for its asset retirement obligations, including the accretion impacts; a $67 million increase in the carrying amount of the associated assets; and a net reduction of $192 million in accumulated depreciation related primarily to the reversal of previously recorded accumulated decommissioning and other removal costs related to these obligations. Additionally, APS recorded a net regulatory liability of $40 million for the asset retirement obligations related to its regulated assets. This regulatory liability represents the difference between the amount currently being recovered in regulated rates and the amount calculated under SFAS No. 143. APS believes it can recover in regulated rates the transition costs and ongoing current period costs calculated in accordance with SFAS No. 143. The adoption of SFAS No. 143 did not have a material impact on our net income for the quarters ended March 31, 2003 and June 30, 2003.

In accordance with SFAS No. 71, APS will continue to accrue for removal costs for its regulated assets, even if there is no legal obligation for removal. At June 30, 2003, accumulated depreciation shown on our Condensed Consolidated Balance Sheets included approximately $379 million of estimated future removal costs that are not considered legal obligations.

The following schedule shows the change in our asset retirement obligations during the six-month period ended June 30, 2003 (dollars in millions):

Balance at January 1, 2003	$	219
Changes attributable to:
Liabilities incurred	—
Liabilities settled	—
Accretion expense	8
Estimated cash flow revisions	—
Balance at June 30, 2003	$	227

The following schedule shows the change in our pro forma liability for the years ended December 31, 2002 and 2001, as if we had recorded an asset retirement obligation based on the guidance in SFAS No. 143 (dollars in millions):

	2002	2001
Balance at beginning of year	$204	$190
Accretion expense	15	14
Balance at end of year	$219	$204

The pro forma effects on net income for 2002 and 2001 are immaterial.

To fund the costs APS expects to incur to decommission the plant, APS established external decommissioning trusts in accordance with NRC regulations. APS invests the trust funds primarily in fixed income securities and domestic stock and classifies them as

available for sale. The following table shows the cost and fair value of APS’ nuclear decommissioning trust fund assets which are reported in investments and other assets on the Condensed Consolidated Balance Sheets at June 30, 2003 and December 31, 2002 (dollars in millions):

	June 30, 2003		December 31, 2002
Trust fund assets — at cost
Fixed income securities	$	116	$	113
Domestic stock	73		68
Total	$	189	$	181

Trust fund assets — at fair value
Fixed income securities	$	117	$	117
Domestic stock	89		77
Total	$	206	$	194

14. Intangible Assets

The Company’s gross intangible assets (which are primarily software) were $241 million at June 30, 2003 and $214 million at December 31, 2002. The increase in gross intangible assets is primarily new software. The related accumulated amortization was $118 million at June 30, 2003 and $104 million at December 31, 2002. Amortization expense for the three months ended June 30 was $7 million in 2003 and $5 million in 2002. Amortization expense for the six months ended June 30 was $14 million in 2003 and $9 million in 2002. Amortization expense for the twelve months ended June 30 was $26 million in 2003 and $21 million in 2002. Estimated amortization expense on existing intangible assets over the next five years is $28 million in 2003, $27 million in 2004, $26 million in 2005, $23 million in 2006 and $16 million in 2007.

15. Stock-Based Compensation

In 2002, we began applying the fair value method of accounting for stock-based compensation, as provided for in SFAS No. 123, “Accounting for Stock-Based Compensation.” In accordance with the transition requirements of SFAS No. 123, as amended by SFAS No. 148, “Accounting for Stock-Based Compensation — Transition and Disclosure,” we applied the fair value method prospectively, beginning with 2002 stock grants. In prior years, we recognized stock compensation expense based on the intrinsic value method allowed in Accounting Principles Board Opinion (APB) No. 25, “Accounting for Stock Issued to Employees.”

The following chart compares our net income, stock compensation expense and earnings per share for the three, six and twelve months ended June 30, 2003 and 2002 to what those items would have been if we had recorded stock compensation expense based on the fair value method for all stock grants through June 30, 2003 (dollars in thousands, except per share amounts):

	Three Months Ended June 30,				Six Months Ended June 30,				Twelve Months Ended June 30,

(a) Primarily related to El Dorado’s investment in NAC in 2002 (see Note 12).

(b) As defined by the FERC, includes below-the-line non-operating utility costs (primarily community relations and environmental compliance).

17. Guarantees

On January 1, 2003 we adopted FIN No. 45, “Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others.” FIN No. 45 elaborates on the disclosures to be made by a guarantor in its financial statements about its obligations under certain guarantees. It also clarifies that a guarantor is required to recognize, at inception of a guarantee, a liability for the fair value of the obligation undertaken in issuing the guarantee. The disclosure provisions are effective for the year ended December 31, 2002. The initial recognition and measurement provisions of FIN No. 45 are effective on a prospective basis to guarantees issued or modified after December 31, 2002.

We have issued parental guarantees and letters of credit and obtained surety bonds on behalf of our unregulated subsidiaries. Our parental guarantees related to Pinnacle West Energy primarily consist of equipment and performance guarantees related to our generation construction program, transmission service guarantees for West Phoenix Units 4 and 5 and long-term service agreement guarantees for new power plants. Our credit support instruments enable APS Energy Services to provide commodity energy and energy-related products and enable El Dorado to support the activities of NAC. SunCor has a debt guarantee on behalf of an affiliated joint venture. Non-performance or payment under the

original contract by our unregulated subsidiaries would require us to perform under the guarantee or surety bond. No liability is currently recorded on the Condensed Consolidated Balance Sheets related to Pinnacle West’s guarantees on behalf of its subsidiaries. Our guarantees have no recourse (except NAC) or collateral provisions to allow us to recover amounts paid under the guarantee. The amounts and approximate terms of our guarantees and surety bonds for each subsidiary at June 30, 2003 are as follows (dollars in millions):

	Guarantees			Surety Bonds			Letters of Credit
	Amount		Term (in years)	Amount		Term (in years)	Amount		Term (in years)
Parental:
Pinnacle West Energy	$	103	1 to 2	$	—		$	36	1 to 2
APS Energy Services	74		1 to 2	47		2	—
El Dorado (all NAC)	44		1 to 3	—			3		1
SunCor guarantees	34		1	—			—
Total	$	255		$	47		$	39

At June 30, 2003, we had entered into approximately $36 million of letters of credit which support various construction agreements. These letters of credit expire in 2003 and 2004. We have approximately $4 million of letters of credit related to worker's compensation expiring in 2004. We intend to provide from either existing or new facilities for the extension, renewal or substitution of the letters of credit to the extent required.

APS has entered into various agreements that require letters of credit for financial assurance purposes. At June 30, 2003, approximately $200 million of letters of credit were outstanding to support existing pollution control bonds of approximately $200 million. The letters of credit are available to fund the payment of principal and interest of such debt obligations. These letters of credit have expiration dates in 2003. APS has also entered into approximately $113 million of letters of credit to support certain equity lessors in the Palo Verde sale-leaseback transactions. These letters of credit expire in 2005. Additionally, APS has approximately $5 million of letters of credit related to counterparty collateral requirements expiring in 2003. APS intends to provide from either existing or new facilities for the extension, renewal or substitution of the letters of credit to the extent required.

In conjunction with our financing agreements, including our sale-leaseback transactions, we generally provide indemnifications relating to liabilities arising from or related to the agreements, except with certain limited exceptions depending on the particular agreement. APS has also provided indemnifications to the equity participants and other parties in the Palo Verde sale-leaseback transactions with respect to certain tax matters. Generally, a maximum obligation is not explicitly stated in the indemnification and therefore, the overall maximum amount of the obligation under such indemnifications cannot be reasonably estimated. Based on historical experience and evaluation of the specific indemnities, we do not believe that any material loss related to such indemnifications is likely and therefore no related liability has been recorded.

18. Earnings Per Share

The following table presents earnings per weighted average common share outstanding for the three, six and twelve months ended June 30, 2003 and 2002:

	Three Months Ended June 30,				Six Months Ended June 30,				Twelve Months Ended June 30

The following table reconciles weighted-average common shares outstanding — basic to weighted-average common shares outstanding — diluted that are used in the earnings per share calculation in the Condensed Consolidated Statements of Income for the three, six and twelve months ended June 30, 2003 and 2002 (in thousands):

	Three Months Ended June 30,		Six Months Ended June 30,		Twelve Months Ended June 30,
	2003	2002	2003	2002	2003	2002
Weighted-average common shares outstanding — basic	91,258	84,794	91,257	84,769	88,121	84,734

Weighted-average common shares outstanding — diluted	91,450	84,926	91,402	84,910	88,276	84,888

Options to purchase 1,784,168 shares for the three month period ended June 30, 2003, 2,026,228 shares for the six month period ended June 30, 2003 and 2,064,575 shares for the twelve month period ended June 30, 2003 were outstanding but were not included in the computation of earnings per share because the options’ exercise prices were greater than the average market price of the common shares. Options to purchase shares of common stock that were not included in the computation of diluted earnings per share were 1,070,045 shares for the three months ended June 30, 2002, 1,072,572 shares for the six months ended June 30, 2002 and 928,152 shares for the twelve months ended June 30, 2002.

19. Real Estate Activities — Discontinued Operations

On January 1, 2002 we adopted SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets.” Among other things, SFAS No. 144 prescribes accounting for discontinued operations and defines certain real estate activities as discontinued operations.

In the first quarter of 2003, SunCor sold its water utility company, which resulted in an after tax gain of $5 million ($8 million pretax). The gain on the sale and operating income in the current and prior periods are classified as discontinued operations on our Condensed Consolidated Statements of Income.

In the second quarter of 2002, SunCor sold a retail center, but maintained a significant continuing involvement through a management contract. In the first quarter of 2003, this management contract was canceled. As a result, the gain on the 2002 sale and the operating income related to this property have been reclassified as discontinued operations. The income from discontinued operations in the three, six and twelve months ended June 30, 2002 primarily reflects this sale.

The following chart provides a summary of SunCor’s earnings (after income taxes) for the three, six and twelve months ended June 30, 2003 and the comparable prior year periods (dollars in millions):

	Three Months Ended June 30,				Six Months Ended June 30,				Twelve Months Ended June 30,

PINNACLE WEST CAPITAL CORPORATION

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

Introduction

In this Item, we explain the results of operations, general financial condition and outlook for Pinnacle West and our subsidiaries: APS, Pinnacle West Energy, APS Energy Services, SunCor and El Dorado, including:

• the changes in our earnings for the three, six and twelve months ended June 30, 2003 and 2002;

• our capital needs, liquidity and capital resources;

• our business outlook and major factors that affect our financial outlook (see Note 5 and “Business Outlook” below); and

• our management of market risks.

We suggest this section be read along with the 2002 10-K and the March 2003 10-Q. Throughout this Item, we refer to specific “Notes” in the Notes to Condensed Consolidated Financial Statements in this report. These Notes add further details to the discussion. Operating statistics for the three, six and twelve months ended June 30, 2003 and 2002 are available on our website (www.pinnaclewest.com) and in our Current Report on Form 8-K dated June 30, 2003.

Overview of Our Business

The Company owns all of the outstanding common stock of APS. APS is an electric utility that provides either retail or wholesale electric service to substantially all of the state of Arizona, with the major exceptions of the Tucson metropolitan area and about one-half of the Phoenix metropolitan area. Electricity is delivered through a distribution system owned by APS. APS also generates, sells and delivers electricity to wholesale customers in the western United States. APS does not distribute any products. The marketing and trading segment sells, in the wholesale market, APS and Pinnacle West Energy generation output that is not needed for APS’ Native Load, which includes loads for retail customers and traditional cost-of-service wholesale customers. In early 2003, we moved our marketing and trading division from Pinnacle West to APS for future marketing and trading activities (existing wholesale contracts remain at Pinnacle West) as a result of the ACC’s Track A Order prohibiting the previously required transfer of APS’ generating assets to Pinnacle West Energy.

Our other major subsidiaries are:

• Pinnacle West Energy, through which we conduct our competitive electricity generation operations;

• APS Energy Services, which provides competitive commodity-related energy services (such as direct access commodity contracts, energy procurement and energy supply consultation) and energy-related products and services (such as energy master planning, energy use consultation and facility audits, cogeneration analysis and installation and project management) to commercial, industrial and institutional retail customers in the western United States;

• SunCor, a developer of residential, commercial and industrial real estate projects in Arizona, New Mexico and Utah; and

• El Dorado, which owns a majority interest in NAC (specializing in spent nuclear fuel technology) and holds miscellaneous small investments, including interests in Arizona community-based ventures.

Earnings Contributions By Subsidiary And Business Segment

We have three principal business segments (determined by products, services and the regulatory environment):

• our regulated electricity segment, which consists of regulated traditional retail and wholesale electricity businesses and related activities and includes electricity generation, transmission and distribution;

• our real estate segment, which consists of SunCor’s real estate development and investment activities.

The following tables summarize net income and segment details for the three, six and twelve months ended June 30, 2003 and the comparable prior periods for Pinnacle West and each of our subsidiaries (dollars in millions):

(a) See “Real Estate Activities” discussion below and Note 19.

(b) Consistent with APS’ October 2001 ACC filing, APS entered into contracts with its affiliates to buy power through June 2003. The contracts reflect a price based on the fully-dispatchable dedication of the Pinnacle West Energy generating assets to APS’ Native Load customers (customers receiving power under traditional cost-based rate regulation). Beginning July 1, 2003, under the ACC Track B order, APS was required to solicit bids for certain estimated capacity and energy requirements. Pinnacle West Energy bid on and entered into a contract to supply most of these purchase power requirements in summer months through September 2006. See “Track B Order” in Note 5 for more information.

(c) APS Energy Services’ net income prior to 2003 and El Dorado’s net income are primarily reported before income taxes. The income tax expense or benefit for these subsidiaries was recorded at the parent company.

(d) Primarily includes activities related to El Dorado in the twelve months ended June 30, 2003, principally El Dorado’s investment in NAC. For the twelve months ended June 30, 2003, we recorded a pretax loss of $47 million related to NAC contracts with two customers. See Note 12.

(e) In the fourth quarter of 2002, Pinnacle West Energy recorded a charge related to the cancellation of Redhawk Units 3 and 4 of approximately $30 million after income taxes ($49 million pretax).

(f) We recorded a $66 million after tax charge as of October 1, 2002 for the cumulative effect of a change in accounting for trading activities, for the early adoption of EITF 02-3.

(g) APS recorded a $12 million after tax charge in July 2001 for the cumulative effect of a change in accounting for derivatives related to the adoption of SFAS No. 133.

Results of Operations

General

Throughout the following explanations of our results of operations, we refer to “gross margin.” With respect to our regulated electricity segment and our marketing and trading segment, gross margin refers to electric operating revenues less purchased power and fuel costs. Our real estate segment gross margin refers to real estate revenues less real estate operations costs of SunCor. Other gross margin refers to other operating revenues less other operating expenses, which includes El Dorado’s investment in NAC, which we began consolidating in our financial statements in July 2002. Other gross margin also includes amounts related to APS Energy Services’ energy consulting services.

Operating Results — Three-month period ended June 30, 2003 compared with three-month period ended June 30, 2002

Our consolidated net income for the three months ended June 30, 2003 was $56 million compared with $75 million for the prior year. The period-to-period decrease of $19 million was primarily due to (amounts after tax):

• $13 million of higher purchased power and fuel costs primarily due to higher hedged gas and power prices;

• $5 million of higher depreciation, operations and maintenance and net interest expense, net of decreased purchased power costs and increased generation sales other than Native Load, related to new power plants in service;

• $5 million of lower SunCor earnings contributions primarily due to the sale of a retail center in the prior year period which was reported as discontinued operations on the Condensed Consolidated Statements of Income, see “Real Estate Activities” below for further discussion;

• a $4 million earnings decrease due to a retail electricity price reduction;

• $4 million of higher operating costs primarily related to higher pension and other benefit costs;

• $3 million of higher depreciation expense primarily related to increased plant assets in service; and

• $1 million of miscellaneous factors, net.

The above decreases were partially offset by (amounts after tax):

• $8 million of higher retail sales primarily due to customer growth, excluding weather effects;

• $4 million of lower regulatory asset amortization; and

• $4 million of higher income as a result of the absence of NAC losses in 2003.

For additional details, see the following discussion.

The major factors that increased (decreased) net income were as follows (dollars in millions)

Regulated Electricity Segment Gross Margin

Regulated electricity segment revenues related to our regulated retail and wholesale electricity businesses were $10 million higher in the three months ended June 30, 2003, compared with the same period in the prior year as a result of:

• a $7 million decrease in retail revenues related to a reduction in retail electricity prices;

• a $20 million increase in retail revenues related to customer growth, excluding weather effects;

• a $2 million decrease in retail revenues related to weather; and

• a $1 million net decrease due to other miscellaneous factors.

Regulated electricity segment purchased power and fuel costs were $20 million higher in the three months ended June 30, 2003, compared with the same period in the prior year as a result of:

• a $22 million increase in purchased power and fuel costs primarily due to higher hedged gas and power prices;

• a $6 million increase related to customer growth, excluding weather effects;

• a $1 million decrease related to the effects of weather on retail sales;

• a $6 million decrease in purchased power costs due to new power plants in service; and

• a $1 million decrease due to other miscellaneous factors.

Marketing and Trading Segment Gross Margin

Marketing and trading segment revenues were $118 million higher in the three months ended June 30, 2003, compared with the same period in the prior year as a result of:

• $77 million of higher realized wholesale revenues primarily due to higher volumes and higher prices;

• $2 million in lower mark-to-market gains for future delivery primarily as a result of lower market liquidity;

• $8 million of higher revenues related to the adoption of EITF 02-3;

• a $17 million increase from higher competitive retail sales in California by APS Energy Services; and

• an $18 million increase from generation sales other than Native Load primarily due to higher sales volumes and higher prices.

Marketing and trading segment purchased power and fuel costs were $117 million higher in the three months ended June 30, 2003, compared to the same period in the prior year as a result of:

• an $83 million increase in purchased power costs related to other realized marketing activities in the current period primarily due to higher volumes and higher prices;

• a $2 million increase in mark-to-market fuel costs for future delivery;

• a $15 million increase in purchased power costs related to higher competitive retail sales in California by APS Energy Services; and

• a $17 million increase in fuel costs related to generation sales other than Native Load primarily because of higher natural gas prices and higher sales volumes.

Other Income Statement Items

The increase in operations and maintenance expense of $13 million was due to increased pension and other benefit costs, new power plants in service, a prior period reversal of APS Energy Services’ California reserve and other costs.

Net interest expense increased $7 million primarily because of higher debt balances and lower capitalized interest related to our generation construction program, including completion of Redhawk Units 1 and 2 in mid-2002.

The increase in depreciation and amortization expense of $5 million primarily related to increased plant assets and new power plants, partially offset by lower regulatory asset amortization.

The increase in other gross margin of $2 million was primarily due to increased NAC gross margins.

The decrease in other expense of $8 million primarily related to the absence of NAC losses of $6 million in 2003 and lower other expenses.

The increase in real estate segment gross margin of $2 million was primarily due to higher home sales. In addition, in the 2003 period, discontinued operations of $1 million after tax primarily related to SunCor’s sale of its water utility company. In the 2002 period, discontinued operations of $6 million after tax primarily related to SunCor’s sale of a retail center (see “Real Estate Activities” below and Note 19).

Operating Results — Six-month period ended June 30, 2003 compared with six-month period ended June 30, 2002

Our consolidated net income for the six months ended June 30, 2003 was $81 million compared with $129 million for the prior year. Both periods include income from discontinued operations related to our real estate segment. The period-to-period decrease of $48 million was primarily due to (amounts after tax):

• $20 million of lower earnings contributions from our marketing and trading activities, reflecting lower liquidity and higher price volatility in the wholesale power markets in the western United States, partially offset by higher revenues related to the adoption of EITF 02-3;

• $16 million of higher depreciation, operations and maintenance and net interest expense, net of decreased purchased power costs and increased generation sales other than Native Load, related to new power plants in service;

• $14 million of higher purchased power and fuel costs primarily due to higher hedged gas and power prices;

• $8 million of higher operating costs primarily related to higher pension and other benefit costs;

• a $7 million earnings decrease due to a retail electricity price reduction;

• $7 million of higher depreciation expense related to increased plant assets in service;

• $4 million from the effects of weather on retail sales; and

• $6 million of miscellaneous factors, net.

The above decreases were partially offset by (amounts after tax):

• $13 million of higher retail sales primarily due to customer growth, excluding weather effects;

• $8 million of lower regulatory asset amortization;

• $7 million related to the absence of NAC losses in 2003 and the current period settlement of an NAC contract dispute (see Note 12); and

• $6 million in higher competitive retail sales in California by APS Energy Services.

• a $38 million increase in purchased power costs related to higher competitive retail sales in California by APS Energy Services; and

• a $52 million increase in fuel costs related to generation sales other than Native Load primarily because of higher natural gas prices and higher sales volumes.

Other Income Statement Items

The increase in operations and maintenance expense of $28 million was due to increased pension and other benefit costs, new power plants in service and increased customer service costs.

Net interest expense increased $14 million primarily because of higher debt balances and lower capitalized interest related to our generation construction program, including completion of Redhawk Units 1 and 2 in mid-2002.

The increase in depreciation and amortization expense of $11 million primarily related to new power plants and increased plant assets, partially offset by lower regulatory asset amortization.

The increase in other gross margin of $8 million was primarily due to NAC’s $5 million reversal of loss reserves related to the settlement of a contract (see Note 12).

The decrease in other expense of $7 million primarily related to prior period NAC losses (see Note 12).

Operating Results — Twelve-month period ended June 30, 2003 compared with twelve-month period ended June 30, 2002

Our consolidated net income for the twelve months ended June 30, 2003 was $102 million compared with $315 million for the prior year. The period-to-period decrease of $213 million was primarily due to (amounts after tax):

• a $66 million charge for the cumulative effect of a change in accounting for trading activities for the early adoption of EITF 02-3 on October 1, 2002;

• $61 million of lower earnings contributions from our marketing and trading activities, reflecting lower liquidity and lower price volatility in the wholesale power markets in the western United States, partially offset by higher revenues related to the adoption of EITF 02-3;

• $37 million of higher purchased power and fuel prices primarily due to higher hedged gas and power prices;

• $34 million of higher operations and maintenance expenses related to the Redhawk Units 3 and 4 cancellation charge and 2002 severance costs, partially offset by lower generation reliability costs;

• $25 million in losses related to our investment in NAC;

• $19 million of higher depreciation, operations and maintenance and net interest expense, net of decreased purchased power costs and increased generation sales other than Native Load, related to new power plants in service;

The above decreases were partially offset by (amounts after tax):

• $26 million of higher retail sales primarily due to customer growth, excluding weather effects;

• $17 million in higher competitive retail sales in California by APS Energy Services;

• $17 million of lower regulatory asset amortization;

• $13 million of 2001 charges related to Enron and its affiliates; and

• a $12 million charge for the cumulative effect of a change in accounting for derivatives, as required by SFAS No. 133, recorded in the twelve months ended June 30, 2002.

Regulated Electricity Segment Gross Margin

Regulated electricity segment revenues related to our regulated retail and wholesale electricity businesses were $259 million lower in the twelve months ended June 30, 2003, compared with the same period in the prior year as a result of:

• an $18 million increase related to traditional wholesale sales as a result of higher prices and higher sales volumes;

• a $281 million decrease related to retail load hedge management wholesale sales primarily as a result of lower prices and lower sales volumes;

• a $27 million decrease in retail revenues related to reductions in retail electricity prices;

• a $37 million decrease in retail revenues related to milder weather;

• a $63 million increase in retail revenues related to customer growth and higher average usage, excluding weather effects; and

• a $5 million net increase due to other miscellaneous factors.

Regulated electricity segment purchased power and fuel costs were $230 million lower in the twelve months ended June 30, 2003, compared with the same period in the prior year as a result of:

• an $18 million increase related to traditional wholesale sales as a result of higher prices and higher sales volumes;

• a $257 million decrease related to retail load hedge management wholesale sales primarily as a result of lower prices and lower sales volumes;

• a $37 million increase in purchased power and fuel costs due to higher hedged gas and power prices;

• a $14 million decrease related to the effects of milder weather on retail sales;

• a $19 million increase related to customer growth, excluding weather effects;

• a $13 million net decrease for charges in 2001 related to purchased power contracts with Enron and its affiliates; and

• a $20 million decrease in purchased power costs due to new power plants in service.

Marketing and Trading Segment Gross Margin

Marketing and trading segment revenues were $247 million higher in the twelve months ended June 30, 2003, compared with the same period in the prior year as a result of:

• $98 million in lower mark-to-market gains for future delivery primarily as a result of lower market liquidity and lower price volatility;

• $117 million of higher realized wholesale revenues primarily due to higher volumes, partially offset by lower prices;

• a $111 million increase from higher competitive retail sales in California by APS Energy Services;

• $25 million of higher revenues related to the adoption of EITF 02-3;

• an $84 million increase from generation sales other than Native Load primarily due to higher sales volumes and higher prices; and

• an $8 million increase due to the 2001 write-off of prior period mark-to-market value related to trading with Enron and its affiliates.

Marketing and trading segment purchased power and fuel costs were $306 million higher in the twelve months ended June 30, 2003, compared to the same period in the prior year as a result of:

• a $147 million increase in purchased power costs related to other realized marketing activities in the current period primarily due to higher volumes and higher prices;

• an $83 million increase in purchased power costs related to higher competitive retail sales in California by APS Energy Services; and

• a $76 million increase in fuel costs related to generation sales other than Native Load primarily because of higher sales volumes and higher natural gas prices.

Other Income Statement Items

The increase in operations and maintenance expense of $94 million was due to a $47 million write-off related to the cancellation of Redhawk Units 3 and 4, severance costs of $36 million related to a 2002 voluntary workforce reduction, increased pension and other benefit costs of $18 million, new power plants in service of $17 million and other costs of $1 million, partially offset by lower costs related to generation reliability of $25 million.

The decrease in other gross margin of $37 million was primarily due to losses on El Dorado’s investment in NAC, partially offset by increased margin on APS Energy Services’ non-commodity sales. Total NAC losses for the twelve month period ended June 30, 2003 totaled approximately $47 million on a pretax basis and were primarily related to contracts with two customers. We reversed $5 million of loss reserves in the first quarter of 2003 related to NAC’s settlement of one of those contracts. We believe we have reserved our exposure with respect to these contracts in all material respects and, as a result, we consider these charges to be non-recurring. See Note 12.

The decrease in other expense of $7 million is primarily related to the absence of NAC losses of $4 million in 2003 recorded as other expense and prior period non-operating costs.

Net interest expense increased $30 million primarily because of higher debt balances related to our generation construction program and lower capitalized interest on our generation construction program due to completion of Redhawk Units 1 and 2 in mid-2002.

The increase in depreciation and amortization expense of $17 million primarily related to new power plants and increased plant assets, partially offset by lower regulatory amortization.

The increase in taxes other than income taxes of $6 million is primarily due to increased property taxes on higher property balances.

The decrease in real estate segment gross margin of $4 million was primarily due to lower commercial and property management sales, partially offset by higher home sales activities. In addition, as discussed in “Real Estate Activities” below and Note 19, SunCor had a $14 million ($8 million after tax) gain on the sale of its water utility company included in discontinued operations for the twelve months ended June 30, 2003 and a $12 million ($7 million after tax) gain related primarily to the sale of a retail center included in discontinued operations in the twelve months ended June 30, 2002.

Real Estate Activities

As discussed in our 2002 10-K, we have undertaken an aggressive effort to accelerate asset sales activities to approximately double SunCor’s annual earnings in 2003 to 2005 compared with the $19 million in earnings recorded in 2002.

Certain components of SunCor’s real estate sales activities, which are included in the real estate segment, may be required to be reported as discontinued operations on our Condensed Consolidated Statements of Income in accordance with SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets.” Among other things, SFAS No. 144 prescribes accounting for discontinued operations and defines certain real estate activities as discontinued operations. We adopted SFAS No. 144 effective January 1, 2002 and determined that activities that would have required discontinued operations reporting in 2002, 2001 and 2000 were immaterial. We currently estimate that 15% to 30% of SunCor’s net income in 2003 will be reported in discontinued operations; however, this ultimately depends on the specific properties sold.

The following chart provides a summary of SunCor’s earnings (after income taxes) for the three, six and twelve months ended June 30, 2003 and the comparable prior periods (dollars in millions):

	Three Months Ended June 30,				Six Months Ended June 30,				Twelve Months Ended June 30,

(a) As discussed in Note 5 under “APS General Rate Case and Retail Rate Adjustment Mechanisms,” as part of its 2003 general rate case, APS requested rate base treatment of the PWEC Dedicated Assets.

(b) See “Capital Resources and Cash Requirements — Pinnacle West Energy” below for further discussion of Pinnacle West Energy’s generation construction program. These amounts do not include an expected reimbursement in 2004 by SNWA of about $100 million, assuming SNWA exercises its option to purchase a 25% interest in the Silverhawk project at that time.

(c) Consists primarily of capital expenditures for land development and retail and office building construction reflected in the “Change in real estate investments” in the Condensed Consolidated Statements of Cash Flows.

(d) Primarily related to the parent company and APS Energy Services.

Delivery capital expenditures are comprised of T&D infrastructure additions and upgrades, capital replacements, new customer construction and related information systems and facility costs. Examples of the types of projects included in the forecast

include T&D lines and substations, line extensions to new residential and commercial developments and upgrades to customer information systems. In addition, APS began several major transmission projects in 2001, with additional major projects scheduled to begin over the next several years. These projects are periodic in nature and are driven by strong regional customer growth. APS expects to spend about $100 million on major transmission projects during the 2003 to 2005 time frame, and these amounts are included in “APS-Delivery” in the table above.

Generation capital expenditures are comprised of various improvements for APS’ existing fossil and nuclear plants and the replacement of Palo Verde steam generators. Examples of the types of projects included in this category are additions, upgrades and capital replacements of various power plant equipment such as turbines, boilers and environmental equipment. Generation also contains nuclear fuel expenditures of approximately $30 million annually for 2003 to 2005.

Replacement of the steam generators in Palo Verde Unit 2 is presently scheduled for completion during the fall outage of 2003. The Palo Verde owners have approved the manufacture of two additional sets of steam generators. We expect that these generators will be installed in Units 1 and 3 in the 2005 to 2007 time frame. Our portion of steam generator expenditures for Units 1, 2 and 3 is approximately $155 million, which will be spent from 2003 through 2008. In 2003 through 2005, $106 million of the costs are included in the generation capital expenditures table above and would be funded with internally-generated cash or external financings.

Capital Resources and Cash Requirements

Contractual Obligations The following table summarizes actual contractual requirements for the six months ended June 30, 2003 and estimated contractual commitments for the next five years and thereafter (dollars in millions):

Off-Balance Sheet Arrangements

APS is exposed to losses under the Palo Verde sale-leaseback agreements upon the occurrence of certain events that APS does not consider to be reasonably likely to occur. Under certain circumstances (for example, the NRC issuing specified violation orders with respect to Palo Verde or the occurrence of specified nuclear events), APS would be required to assume the debt associated with the transactions, make specified payments to the equity participants and take title to the leased Unit 2 interests, which, if appropriate, may be required to be written down in value. If such an event had occurred as of June 30, 2003, APS would have been required to assume approximately $268 million of debt and pay the equity participants approximately $200 million.

Guarantees

We and certain of our subsidiaries have issued guarantees and letters of credit in support of our unregulated businesses. We have also obtained surety bonds on behalf of APS Energy Services. We have not recorded any liability on our Condensed Consolidated Balance Sheets with respect to these obligations. See Note 17 for additional information regarding guarantees.

Credit Ratings

The ratings of securities of Pinnacle West and APS as of August 13, 2003 are shown below and are considered to be “investment-grade” ratings. The ratings reflect the respective views of the rating agencies, from which an explanation of the significance of their ratings may be obtained. There is no assurance that these ratings will continue for any given period of time. The ratings may be revised or withdrawn entirely by the rating agencies, if, in their respective judgments, circumstances so warrant. Any downward revision or withdrawal may adversely affect the market price of Pinnacle West’s or APS’ securities and serve to increase those companies’ cost of and access to capital.

Debt Provisions

Pinnacle West’s and APS’ significant debt covenants related to their respective financing arrangements include a debt-to-total-capitalization ratio and an interest coverage test (as defined in the agreements). Pinnacle West and APS are in compliance with such covenants and each anticipates it will continue to meet all the significant covenant requirement levels. The ratio of debt to total capitalization cannot exceed 65% for both the Company and APS. At June 30, 2003, the ratios were appr oximately 56% for the parent company and 54% for APS. The provisions regarding interest coverage require a minimum cash coverage of two times the interest requirements for both the Company and APS. The coverages are approximately 4 times for the parent company, 4 times for the APS bank agreements and 13 times for the APS mortgage indenture. Failure to comply with such covenant levels would result in an event of default which, generally speaking, would require the immediate repayment of the debt subject to the covenants.

Neither Pinnacle West’s nor APS’ financing agreements contain “ratings triggers” that would result in an acceleration of the required interest and principal payments in the event of a ratings downgrade. However, in the event of a ratings downgrade, Pinnacle West and/or APS may be subject to increased interest costs under certain financing agreements.

All of Pinnacle West’s bank agreements contain cross-default provisions that would result in defaults and the potential acceleration of payment under these agreements if Pinnacle West or APS were to default under other agreements. All of APS’ bank agreements contain cro ss-default provisions that would result in defaults and the potential acceleration of payment under these bank agreements if APS were to default under other agreements. Pinnacle West’s and APS’ credit agreements generally contain provisions under which the lenders could refuse to advance loans in the event of a material adverse change in our financial condition or financial prospects.

Pinnacle West (Parent Company)

Our primary cash needs are for dividends to our shareholders; equity infusions into our subsidiaries, primarily Pinnacle West Energy; and interest payments and optional and mandatory repayments of principal on our long-term debt (see the table above for our contractual requirements, including our debt repayment obligations, but excluding optional repayments). The level of our common dividends and future dividend growth will be dependent on a number of factors including, but not limited to, payout ratio trends, free cash flow and financial market conditions.

Our primary sources of cash are dividends from APS, external financings and cash distributions from our other subsidiaries, primarily SunCor. For the years 2000 through 2002, total dividends from APS were $510 million and total distributions from SunCor were $33 million. We expect SunCor to make cash distributions to the parent company of $80 to $100 million annually in 2003 through 2005 due to anticipated accelerated asset sales activity. As discussed in Note 5, APS must maintain a common equity ratio of at least 40% and may not pay common dividends if the payment would reduce its common equity below that threshold. As defined in the Financing Order, common equity ratio is common equity divided by common equity plus long-term debt, including current maturities of long-term debt. At June 30, 2003, APS’ common equity ratio was approximately 45%.

On November 22, 2002, the ACC issued the Interim Financing Order, which permits APS to (a) make short-term advances to Pinnacle West in the form of an inter-affiliate line of credit in the amount of $125 million, or (b) guarantee $125 million of Pinnacle West’s short-term debt, subject to certain conditions. As of June 30, 2003, there were no borrowings outstanding under this financing arrangement.

repaid the outstanding balance ($167 million) under a credit facility. We used a portion of the remaining proceeds to redeem our $250 million Floating Rate Notes due 2003 on June 2, 2003 and to repay other short-term debt.

As part of a multi-employer pension plan sponsored by Pinnacle West, we contribute at least the minimum amount required under IRS regulations, but no more than the maximum tax-deductible amount. The minimum required funding takes into consideration the value of the fund assets and our pension obligation. We elected to contribute cash to our pension plan in each of the last five years; our minimum required contributions during each of those years was zero. Specifically, we contributed $73 million for 2002 ($46 million of which was contributed in June 2003), $24 million for 2001, $44 million for 2000 ($20 million of which was contributed in 2001), $25 million for 1999 and $14 million for 1998. APS and other subsidiaries fund their share of the pension contribution, of which APS represents approximately 90% of the total funding amounts described above. The assets in the plan are mostly domestic common stocks, bonds and real estate. Future year contribution amounts are dependent on fund performance and fund valuation assumptions.

APS

APS’ capital requirements consist primarily of capital expenditures and optional and mandatory redemptions of long-term debt. See “Business Outlook - Regulatory Matters” below and Notes 4 and 5 for discussion of the $500 million financing arrangement between APS and Pinnacle West Energy authorized by the ACC pursuant to the Financing Order and APS’ related issuance of $500 million of debt. See “Pinnacle West (Parent Company)” above and Note 5 for discussion of a $125 million interim financing arrangement between APS and Pinnacle West.

APS pays for its capital requirements with cash from operations and, to the extent necessary, external financings. APS has historically paid for its dividends to Pinnacle West with cash from operations.

On April 7, 2003, APS redeemed approximately $33 million of its First Mortgage Bonds, 8% Series due 2025, and on August 1, 2003, APS redeemed approximately $54 million of its First Mortgage Bonds, 7.25% Series due 2023.

Although provisions in APS’ first mortgage bond indenture, articles of incorporation and ACC financing orders establish maximum amounts of additional first mortgage bonds, debt and preferred stock that APS may issue, APS does not expect any of these provisions to limit its ability to meet its capital requirements.

Pinnacle West Energy

The costs of Pinnacle West Energy’s construction of 2,360 MW of generating capacity from 2000 through 2004 are expected to be about $1.4 billion, of which $1.2 billion has been incurred through June 30, 2003. This does not reflect the proceeds from an anticipated sale in 2004 to SNWA of a 25% interest in the plant, which would equal about $100 million of Pinnacle West Energy’s cumulative capital expenditures in the Silverhawk project. SNWA has committed to purchase a 25% interest in the project upon completion,

subject to an appropriation of funds by SNWA. Pinnacle West Energy is currently funding its capital requirements through capital infusions from Pinnacle West, which finances those infusions through debt and equity financings and internally-generated cash. See the capital expenditures table above for actual capital expenditures in the six months ended June 30, 2003 and projected capital expenditures for the next three years.

Pinnacle West Energy’s generation construction plan is as follows:

• A 650 MW combined cycle expansion of the West Phoenix Power Plant in Phoenix. The 120 MW West Phoenix Unit 4 began commercial operation in June 2001. The 530 MW West Phoenix Unit 5 began commercial operation in July 2003.

• Development of the 570 MW Silverhawk combined-cycle plant 20 miles north of Las Vegas, Nevada. Construction of the plant began in August 2002, with an expected commercial operation date of mid-2004. Pinnacle West Energy has signed an agreement with Las Vegas-based SNWA under which SNWA has an option to purchase a 25% interest in the project for approximately $100 million.

• The Redhawk Power Plant, two 530 MW combined cycle units, near Palo Verde. Commercial operation began in July 2002.

• The construction of an 80 MW simple-cycle power plant at Saguaro in Southern Arizona. Commercial operation began in July 2002.

• Pinnacle West Energy owns a 50% interest in Copper Eagle Gas Storage, a limited liability company established for the purpose of evaluating and developing an underground natural gas storage facility west of Phoenix. The Company is currently evaluating the feasibility of the project and its level of future participation in development.

See Notes 4 and 5 and “Pinnacle West (Parent Company)” above for a discussion of the $500 million financing arrangement between APS and Pinnacle West Energy authorized by the ACC pursuant to the Financing Order.

Other Subsidiaries

During the past three years, SunCor funded its cash requirements with cash from operations and its own external financings. SunCor’s capital needs consist primarily of capital expenditures for land development and retail and office building construction. See the capital expenditures table above for actual capital expenditures in the six months ended June 30, 2003 and projected capital expenditures through 2005. SunCor expects to fund its capital requirements with cash from operations and external financings.

We expect SunCor to make cash distributions to the parent company of $80 to $100 million annually in 2003 through 2005 due to anticipated accelerated asset sales activity.

SunCor has made cash distributions to the parent company in the amount of $33 million through June 30, 2003. See “Real Estate Activities” above and Note 19.

El Dorado funded its cash requirements during the past three years, primarily for NAC in 2002, with cash infused by the parent company and with cash from operations. El Dorado expects minimal capital requirements through 2005.

APS Energy Services’ cash requirements during the past three years were funded with cash infusions from the parent company. APS Energy Services’ capital expenditures and other cash requirements are increasingly funded by operations, with some funding from cash infused by Pinnacle West. See the capital expenditures table above regarding APS Energy Services’ actual capital expenditures for the six months ended June 30, 2003 and projected capital expenditures through 2005.

Critical Accounting Policies

In preparing the financial statements in accordance with GAAP, management must often make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures at the date of the financial statements and during the reporting period. Some of those judgments can be subjective and complex, and actual results could differ from those estimates. Our most critical accounting policies include the impacts of regulatory accounting and the determination of the appropriate accounting for our pension and other postretirement benefits, derivatives and mark-to-market accounting. There have been no changes to our critical accounting policies since our 2002 10-K, except for the discussion related to SFAS No. 143 (see Note 13). See “Critical Accounting Policies” in Item 7 of the 2002 10-K for further details about our critical accounting policies.

Business Outlook

In this section we discuss a number of factors affecting our business outlook.

Regulatory Matters

See Note 5 for a discussion of ACC regulatory matters, including the APS general rate case filed on June 27, 2003.

Wholesale Power Market Conditions

The marketing and trading division focuses primarily on managing APS’ purchased power and fuel risks in connection with its costs of serving retail customer demand. We moved this division to APS in early 2003 for future marketing and trading activities (existing wholesale contracts remain at Pinnacle West) as a result of the ACC’s Track A Order prohibiting APS’ transfer of generating assets to Pinnacle West Energy. Additionally, the marketing and trading division, subject to specified parameters, markets, hedges and trades in electricity, fuels, and emission allowances and credits. Our future earnings will be affected by the strength or weakness of the wholesale power market. The market has suffered a substantial reduction in overall liquidity because there are fewer creditworthy counterparties and because several key participants have exited the market or scaled back their activities. Based on the erosion in the market and on the market outlook for the

remainder of the year, we currently believe that the contribution from our trading activities will be significantly lower in 2003 than in 2002, and will remain at about the 2003 level in 2004.

Generation Construction Plan

See “Liquidity and Capital Resources — Pinnacle West Energy” for information regarding Pinnacle West Energy’s generation construction plan. The planned additional generation is expected to increase revenues, fuel expenses, operating expenses and financing costs.

Factors Affecting Operating Revenues

General Electric operating revenues are derived from sales of electricity in regulated retail markets in Arizona and from competitive retail and wholesale bulk power markets in the western United States. These revenues are expected to be affected by electricity sales volumes related to customer mix, customer growth and average usage per customer as well as electricity prices and variations in weather from period to period. Competitive sales of energy and energy-related products and services are made by APS Energy Services in western states that have opened to competitive supply.

Customer Growth Customer growth in APS’ service territory averaged about 3.6% a year for the three years 2000 through 2002; we currently expect customer growth to average about 3.5% per year from 2003 to 2005. We currently estimate that retail electricity sales in kilowatt-hours will grow 3.5% to 5.5% a year in 2003 through 2005, before the retail effects of weather variations. The customer and sales growth referred to in this paragraph applies to energy delivery customers. Customer growth for the six month period ended June 30, 2003 compared with the prior year period was 3.2%.

Retail Rate Changes As part of the 1999 Settlement Agreement, APS agreed to a series of annual retail electricity price reductions of 1.5% on July 1 for each of the years 1999 to 2003 for a total of 7.5%. The final price reduction was implemented July 1, 2003. See “1999 Settlement Agreement” in Note 5 for further information. In addition, the Company has requested a 9.8% retail rate increase to be effective July 1, 2004. See “APS General Rate Case and Retail Rate Adjustment Mechanisms” in Note 5 for further information.

Other Factors Affecting Future Financial Results

Purchased Power and Fuel Costs Purchased power and fuel costs are impacted by our electricity sales volumes, existing contracts for purchased power and generation fuel, our power plant performance, prevailing market prices, new generating plants being placed in service and our hedging program for managing such costs. See “Natural Gas Supply” in Note 12 for more information on fuel costs.

On August 2, 2003, Unit 3 of the Cholla Power Plant tripped due to a generator failure. Based on testing and unit inspection to date, APS expects the cost to repair the generator to be approximately $7 million, most of which should be covered by insurance, and expects the unit to be back in service by the end of November, 2003. The Company is continuing to evaluate the damage to the unit; however, the Company currently estimates replacement power costs to be approximately $20 million.

Operations and Maintenance Expenses Operations and maintenance expenses are expected to be affected by sales mix and volumes, power plant additions and operations, inflation, outages, higher trending pension and other postretirement benefit costs and other factors. In July 2002, we implemented a voluntary workforce reduction as

part of our cost reduction program. We recorded $36 million before taxes in voluntary severance costs in the second half of 2002.

Depreciation and Amortization Expenses Depreciation and amortization expenses are expected to be affected by net additions to existing utility plant and other property, changes in regulatory asset amortization and our generation construction program. West Phoenix Unit 4 was placed in service in June 2001. Redhawk Units 1 and 2 and the new Saguaro Unit 3 began commercial operations in July 2002. West Phoenix Unit 5 was placed in service in July 2003 and Silverhawk is expected to be in service in mid-2004. The regulatory assets to be recovered under the 1999 Settlement Agreement are currently being amortized as follows (dollars in millions):

1999		2000		2001		2002		2003		2004		Total
$	164	$	158	$	145	$	115	$	86	$	18	$	686

Property Taxes Taxes other than income taxes consist primarily of property taxes, which are affected by tax rates and the value of property in-service and under construction. The average property tax rate for APS, which currently owns the majority of our property, was 9.7% of assessed value for 2002 and 9.3% for 2001. We expect property taxes to increase primarily due to our generation construction program, as the plants phase-in to the property tax base over a five-year period, and our additions to existing facilities.

Interest Expense Interest expense is affected by the amount of debt outstanding and the interest rates on that debt. The primary factors affecting borrowing levels in the next several years are expected to be our capital requirements and our internally generated cash flow. Capitalized interest offsets a portion of interest expense while capital projects are under construction. We stop recording capitalized interest on a project when it is placed in commercial operation. As noted above, we placed new power plants in commercial operation in 2001, 2002 and 2003 and we expect to bring an additional plant on-line in 2004. Interest expense is also affected by interest rates on variable-rate debt and interest rates on the refinancing of the Company’s future liquidity needs.

Retail Competition The regulatory developments and legal challenges to the Rules discussed in Note 5 have raised considerable uncertainty about the status and pace of retail electric competition and of electric restructuring in Arizona. Although some very limited retail competition existed in APS’ service area in 1999 and 2000, there are currently no active retail competitors providing unbundled energy or other utility services to APS’ customers. As a result, we cannot predict when, and the extent to which, additional competitors will re-enter APS’ service territory.

Subsidiaries In the case of SunCor, we are undertaking an aggressive effort to accelerate asset sales activities, which we expect to approximately double SunCor’s annual earnings in 2003 to 2005 compared with the $19 million in earnings recorded in 2002. A portion of these sales have been, and additional amounts may be required to be, reported as discontinued operations on the Condensed Consolidated Statements of Income. See “Real Estate Activities” above and Note 19 for further discussion.

The annual earnings contribution from APS Energy Services is expected to be positive over the next several years due primarily to a number of retail electricity contracts in California. APS Energy Services’ had pretax earnings of $28 million in 2002.

El Dorado’s historical results are not necessarily indicative of future performance for El Dorado. In addition, we do not currently expect material losses related to NAC in the future.

General Our financial results may be affected by a number of broad factors. See “Forward-Looking Statements” below for further information on such factors, which may cause our actual future results to differ from those we currently seek or anticipate.

Risk Factors

Exhibit 99.1, which is hereby incorporated by reference, contains a discussion of risk factors involving the Company.

Forward-Looking Statements

This document contains forward-looking statements based on current expectations and we assume no obligation to update these statements or make any further statements on any of these issues, except as required by applicable law. These forward-looking statements are often identified by words such as “hope,” “may,” “believe,” “anticipate,” “plan,” “expect,” “require,” “intend,” “assume” and similar words. Because actual results may differ materially from expectations, we caution readers not to place undue reliance on these statements. A number of factors could cause future results to differ materially from historical results, or from results or outcomes currently expected or sought by us. These factors include, but are not limited to, the ongoing restructuring of the electric industry, including the introduction of retail electric competition in Arizona and decisions impacting wholesale competition; the outcome of regulatory and legislative proceedings relating to the restructuring; state and federal regulatory and legislative decisions and actions, including the outcome of the rate case we filed with the ACC on June 27, 2003 and the wholesale electric price mitigation plan adopted by the FERC; regional economic and market conditions, including the results of litigation and other proceedings resulting from the California energy situation, volatile purchased power and fuel costs and the completion of generation and transmission construction in the region, which could affect customer growth and the cost of power supplies; the cost of debt and equity capital and access to capital markets; weather variations affecting local and regional customer energy usage; conservation programs; power plant performance; the successful completion of our generation construction program; regulatory issues associated with generation construction, such as permitting and licensing; our ability to compete successfully outside traditional regulated markets (including the wholesale market); our ability to manage our marketing and trading activities and the use of derivative contracts in our business; technological developments in the electric industry; the performance of the stock market, which affects the amount of our required contributions to our pension plan and nuclear decommissioning trust funds; the strength of the real estate market in SunCor’s market areas, which include Arizona, New Mexico and Utah; and other uncertainties, all of which are difficult to predict and many of which are beyond our control.

Item 3. Market Risks

Our operations include managing market risks related to changes in interest rates, commodity prices and investments held by the nuclear decommissioning trust fund and our pension plans.

Commodity Price Risk

We are exposed to the impact of market fluctuations in the commodity price and transportation costs of electricity, natural gas, coal and emissions allowances. We manage risks associated with these market fluctuations by utilizing various commodity derivatives, including exchange-traded futures and options and over-the-counter forwards, options and swaps. The ERMC, consisting of senior officers, oversees company-wide energy risk management activities and monitors the results of marketing and trading activities to ensure compliance with our stated energy risk management and trading policies. As part of our risk management program, we enter into derivative transactions to hedge purchases and sales of electricity, fuels, and emissions allowances and credits. The changes in market value of such contracts have a high correlation to price changes in the hedged commodities. In addition, subject to specified risk parameters monitored by the ERMC, we engage in marketing and trading activities intended to profit from market price movements.

We adopted the EITF 02-3 guidance for all contracts in the fourth quarter of 2002. Our energy trading contracts that are derivatives are accounted for at fair value under SFAS No. 133. Contracts that do not meet the definition of a derivative are accounted for on an accrual basis with the associated revenues and costs recorded at the time the contracted commodities are delivered or received. Additionally, all gains and losses (realized and unrealized) on energy trading contracts that qualify as derivatives are included in marketing and trading segment revenues on the Condensed Consolidated Statements of Income on a net basis. Derivative instruments used for non-trading activities are accounted for in accordance with SFAS No. 133. See Note 10 for details on the change in accounting for energy trading contracts.

Both non-trading and trading derivatives are classified as assets and liabilities from risk management and trading activities in the Condensed Consolidated Balance Sheets. For non-trading derivative instruments that qualify for hedge accounting treatment, changes in the fair value of the effective portion are recognized in common stock equity (as a component of accumulated other comprehensive income (loss)). Non-trading derivatives, or any portion thereof, that are not effective hedges are adjusted to fair value through income. Gains and losses related to non-trading derivatives that qualify as cash flow hedges of expected transactions are recognized in revenue or purchased power and fuel expense as an offset to the related item being hedged when the underlying hedged physical transaction impacts earnings. If it becomes probable that a forecasted transaction will not occur, we discontinue the use of hedge accounting and recognize in income the unrealized gains and losses that were previously recorded in other comprehensive income (loss). In the event a non-trading derivative is terminated or settled, the unrealized gains and losses remain in other comprehensive income (loss) and are recognized in income when the underlying transaction impacts earnings.

Derivatives associated with trading activities are adjusted to fair value through income. Derivative commodity contracts for the physical delivery of purchase and sale quantities transacted in the normal course of business are exempt from the requirements of SFAS No. 133 under the normal purchase and sales exception and are not reflected on the balance sheet at fair value. Most of our non-trading electricity purchase and sales agreements qualify as normal purchases and sales and are exempted from recognition in the financial statements until the electricity is delivered.

Our assets and liabilities from risk management and trading activities are presented in two categories consistent with our business segments:

• System - non-trading derivative instruments that hedge our purchases and sales of electricity and fuel for APS’ Native Load requirements of our regulated electricity business segment; and

• Marketing and Trading - both non-trading and trading derivative instruments of our competitive business segment.

The following tables show the changes in mark-to-market of our system and marketing and trading derivative positions for the six months ended June 30, 2003 and 2002 (dollars in millions):

	Six Months Ended June 30, 2003						Six Months Ended June 30, 2002
	System			Marketing and Trading			System			Marketing and Trading
Mark-to-market of net positions at beginning of period	$	(49	)	$	57		$	(107	)	$	138
Change in mark-to-market gains (losses) for future period deliveries	6			(5		)	(2		)	17
Changes in cash flow hedges recorded in OCI	33			46			47			—
Ineffective portion of changes in fair value recorded in earnings	6			1			2			—
Mark-to-market losses (gains) realized during the period	7			(14		)	7			(22		)
Mark-to-market of net positions at end of period	$	3		$	85		$	(53	)	$	133

Since July 1, 2002, the Company has not recognized a dealer profit or unrealized gain or loss at the inception of a derivative unless the fair value of that instrument (in its entirety) is evidenced by quoted market prices or current market transactions. Prior to the change in our policy, we recorded net gains at inception of $9 million in the six months ended June 30, 2002. These amounts included a reasonable

marketing margin. No net gains at inception were recorded in the six months ended June 30, 2003.

The tables below show the fair value of the system and marketing and trading derivative contracts (dollars in millions) at June 30, 2003 by maturities and by the type of valuation that is performed to calculate the fair values. See “Critical Accounting Policies - Mark-to-Market Accounting” in Item 7 of our 2002 10-K for more discussion on our valuation methods.

The table below shows the impact that hypothetical price movements of 10% would have on the market value of our risk management and trading assets and liabilities included on the Condensed Consolidated Balance Sheets at June 30, 2003 and 2002 (dollars in millions).

	June 30, 2003 Gain (Loss)						June 30, 2002 Gain (Loss)
Commodity	Price Up 10%			Price Down 10%			Price Up 10%			Price Down 10%
Mark-to-market changes reported in earnings (a):
Electricity	$	(3	)	$	3		$	(2	)	$	2
Natural gas	(3		)	3			(1		)	1
Other	1			—			2			(1		)
Mark-to-market changes reported in OCI (b):
Electricity	36			(36		)	—			—
Natural gas	22			(21		)	18			(16		)

Total	$	53		$	(51	)	$	17		$	(14	)

(a) These contracts are structured sales activities hedged with a portfolio of forward purchases that protects the economic value of the sales transactions.

(b) These contracts are hedges of our forecasted purchases of natural gas and electricity. The impact of these hypothetical price movements would substantially offset the impact that these same price movements would have on the physical exposures being hedged.

Credit and Counterparty Risk

We are exposed to losses in the event of nonperformance or nonpayment by counterparties. We have risk management and trading contracts with many counterparties, including one counterparty for which a worst case exposure represents approximately 19% of our $402 million of risk management and trading assets as of June 30, 2003. Our risk management process assesses and monitors the financial exposure of this counterparty and all other counterparties. Despite the fact that the great majority of trading counterparties are rated as investment grade by the credit rating agencies, including the counterparty noted above, there is still a possibility that one or more of these companies could default, resulting in a material impact on consolidated earnings for a given period. Counterparties in the portfolio consist principally of major energy companies, municipalities and local distribution companies. We maintain credit policies that we believe minimize overall credit risk to within acceptable limits. Determination of the credit quality of our counterparties is based upon a number of factors, including credit ratings and our evaluation of their financial condition. In many contracts, we employ collateral requirements and standardized agreements that allow for the netting of positive and negative exposures associated with a single counterparty. We also enter into credit default swap instruments to limit our credit risk related to certain counterparties. Valuation adjustments are established representing our estimated credit losses on our overall exposure to counterparties. See “Critical Accounting Policies — Mark-to-Market Accounting” in Item 7 of our 2002 10-K for more discussion on our valuation methods.

Item 4. Controls and Procedures

(a) Evaluation of Disclosure Controls and Procedures

The Company’s management, with the participation of the Company’s Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness the Company’s disclosure controls and procedures as of the end of the period covered by this report. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures as of the end of the period covered by this report have been designed and are functioning effectively to provide reasonable assurance that the information required to be disclosed by the Company in reports filed under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

(b) Change in Internal Control over Financial Reporting

No change in the Company’s internal control over financial reporting occurred during the Company’s most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

Item 5. Other Information

Construction and Financing Programs

See “Liquidity and Capital Resources” in Part I, Item 2 of this report for a discussion of construction and financing programs of the Company and its subsidiaries.

Regulatory Matters

See Note 5 of Notes to Condensed Consolidated Financial Statements in Part I, Item 1 of this report for a discussion of regulatory developments.

Environmental Matters

Clean Air Act

As previously reported, the EPA has reviewed an “Annex” to the Visibility Commission recommendations that specify the regional sulfur dioxide emission milestones. See “Environmental Matters — Clean Air Act” in Part I, Item 1 of the 2002 10-K. The EPA approved the Annex and issued final rules implementing it in June 2003.

Water Supply

The Four Corners region, in which the Four Corners power plant is located, has been experiencing drought conditions that may affect the water supply for the plants in 2003, as well as later years if adequate moisture is not received in the watershed that supplies the area. See “Environmental Matters — Water Supply” in Item I, Part 1 of the 2002 10-K. We have entered into agreements with various parties to provide additional temporary supplies of water, if required, and are continuing to work with area stakeholders to minimize the effect, if any on operations of the plant. The effect of the drought cannot be fully assessed at this time, and we cannot predict the ultimate outcome, if any, of the drought or whether the drought will adversely affect the amount of power available, or the price thereof, from the Four Corners power plant.

Natural Gas Supply
