SunCor was a developer of residential, commercial and industrial real estate projects in Arizona, New Mexico, Idaho and Utah. All activities for SunCor are now reported as discontinued operations (see Note 22). APSES provides energy-related projects to commercial and industrial retail customers in competitive markets in the western United States. In 2008, APSES discontinued its commodity-related energy services (see Note 22). El Dorado is an investment firm. Pinnacle West Marketing &#038; Trading began operations in early 2007.

The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period.

We manage risks associated with these market fluctuations by utilizing various instruments that qualify as derivatives, including exchange-traded futures and options and over-the-counter forwards, options and swaps. As part of our overall risk management program, we use such instruments to hedge purchases and sales of electricity and fuels. The changes in market value of such contracts have a high correlation to price changes in the hedged transactions. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">We account for our derivative contracts in accordance with derivatives and hedging guidance, which requires that entities recognize all derivatives as either assets or liabilities on the balance sheet and measure those instruments at fair value.

Fair value is the price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between willing market participants on the measurement date. Inputs to fair value include observable and unobservable data. We maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">We determine fair market value using actively-quoted prices for identical instruments when available. When actively quoted prices are not available for the identical instruments we use prices for similar instruments or other corroborative market information or prices provided by other external sources. For options, long-term contracts and other contracts for which price quotes are not available, we use unobservable inputs, such as models and other valuation methods, to determine fair market value. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">The use of models and other valuation methods to determine fair market value often requires subjective and complex judgment. Actual results could differ from the results estimated through application of these methods. Our structured activities are hedged with a portfolio of forward purchases that protects the economic value of the sales transactions. Our practice is to hedge within timeframes established by our executive risk committee. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">See Note 14 for additional information about fair value measurements. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt"><b>Regulatory Accounting</b> </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">APS is regulated by the ACC and the FERC. The accompanying financial statements reflect the rate-making policies of these commissions. As a result, we capitalize certain costs that would be included as expense in the current period by unregulated companies.

Regulatory liabilities generally represent expected future costs that have already been collected from customers. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">Management continually assesses whether our regulatory assets are probable of future recovery by considering factors such as changes in the applicable regulatory environment and recent rate orders applicable to other regulated entities in the same jurisdiction.

Revenues related to the sale of electricity are generally recorded when service is rendered or electricity is delivered to customers. The billing of electricity sales to individual Native Load customers is based on the reading of their meters, which occurs on a systematic basis throughout the month. Unbilled revenues are estimated by applying an average revenue/kWh to the number of estimated kWhs delivered but not billed. Differences historically between the actual and estimated unbilled revenues are immaterial. We exclude sales taxes and franchise fees on electric revenues from both revenue and taxes other than income taxes. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">Revenues from our Native Load customers and non-derivative instruments are reported on a gross basis on Pinnacle West&#8217;s Consolidated Statements of Income. In the electricity business, some contracts to purchase energy are netted against other contracts to sell energy. This is called a &#8220;book-out&#8221; and usually occurs for contracts that have the same terms (quantities and delivery points) and for which power does not flow. We net these book-outs, which reduces both revenues and fuel and purchased power costs. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">Effective January&#160;1, 2010, electric revenues also include proceeds for line extension payments for new or upgraded service in accordance with the 2009 retail rate case settlement agreement (see Note 3). This revenue treatment continues through 2012, or until new rates are established in APS&#8217;s next general retail rate case, if that is before year end 2012. Certain proceeds received under previous versions of the line extension policy, or for activities not involving an extension or upgrade of service (e.g., service relocations at the request of governmental entities or undergrounding of overhead facilities) will continue to be treated as contributions in aid of construction and will not impact electric revenues. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt"><b>Allowance for Doubtful Accounts</b> </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">The allowance for doubtful accounts represents our best estimate of existing accounts receivable that will ultimately be uncollectible. The allowance is calculated by applying estimated write-off factors to various classes of outstanding receivables, including accrued utility revenues.

Land included acquisition costs, infrastructure costs, capitalized interest and property taxes directly associated with the acquisition and development of each project. Home inventory consisted of construction costs, improved lot costs, capitalized interest and property taxes on homes and condos under construction. Homes under construction were classified as &#8220;real estate investments&#8221; on the Consolidated Balance Sheets; upon completion of construction they transferred to &#8220;home inventory&#8221; with the expectation that they would be sold in a timely manner. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">For the purposes of evaluating impairment, in accordance with the provisions on accounting for the impairment or disposal of long-lived assets, we classified our real estate assets, such as land under development, land held for future development, and commercial property as &#8220;held and used.&#8221; When events or changes in circumstances indicated that the carrying values of real estate assets considered held and used would not be recoverable, we compared the undiscounted cash flows that we estimated would be generated by each asset to its carrying amount. If the carrying amount exceeded the undiscounted cash flows, we adjusted the asset to fair value and recognized an impairment charge. The adjusted value became the new book value (carrying amount) for held and used assets.

We file our federal income tax return on a consolidated basis and we file our state income tax returns on a consolidated or unitary basis. In accordance with our intercompany tax sharing agreement, federal and state income taxes are allocated to each first-tier subsidiary as though each first-tier subsidiary filed a separate income tax return. Any difference between that method and the consolidated (and unitary) income tax liability is attributed to the parent company. The income tax liability accounts reflect the tax and interest associated with management&#8217;s estimate of the largest amount of tax benefit that is greater than 50% likely of being realized upon settlement for all known and measurable tax exposures.

This amended guidance significantly changed the consolidation model for VIEs. Under the prior guidance the consolidation model considered risk absorption using a quantitative approach when determining the primary beneficiary. The consolidation model under the new guidance requires a qualitative assessment and focuses on the power to direct activities of the VIE when determining the primary beneficiary. As a result of applying this qualitative assessment, we have determined that APS is the primary beneficiary of certain VIEs relating to the Palo Verde Unit 2 sale leaseback transactions, and is therefore required to consolidate these VIEs. Prior to adopting this new guidance, APS was not considered the primary beneficiary of these VIEs and did not consolidate these entities. We have adopted this guidance using retrospective application and have adjusted prior periods presented to reflect consolidation of the VIEs in those periods (see Note 1).

Under the RES, electric utilities that are regulated by the ACC must supply an increasing percentage of their retail electric energy sales from eligible renewable resources, including solar, wind, biomass, biogas and geothermal technologies. In order to achieve these requirements, the ACC allows APS to include a RES surcharge as part of customer bills to recover the approved amounts for use on renewable energy projects. Each year APS is required to file a five-year implementation plan with the ACC and seek approval for funding the upcoming year&#8217;s RES budget. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">During 2009, APS filed its annual RES implementation plan, covering the 2010-2014 timeframe and requesting 2010 RES funding approval. The plan provided for the acquisition of renewable generation in compliance with requirements through 2014, and requested RES funding of $87&#160;million for 2010, which was later approved by the ACC. APS also sought various other determinations in its plan, including approval of the AZ Sun Program and the Community Power Project in Flagstaff, Arizona described below. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">On March&#160;3, 2010, the ACC approved the AZ Sun Program, which contemplates the addition of 100 MW of APS-owned solar resources through 2014. Through this program, APS plans to invest up to $500 million in solar photovoltaic projects across Arizona, which APS will acquire through competitive procurement processes. The costs associated with the first 50 MW under this program will be recovered initially through the RES until such time as the costs are recovered in base rates or other mechanisms. The costs of the second 50 MW will be recovered through a mechanism to be determined in APS&#8217;s next retail rate case. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">On April&#160;1, 2010, the ACC approved the Community Power Project, a pilot program in which APS will own, operate and receive energy from approximately 1.5 MW of solar panels on the rooftops of up to 200 residential and business customers located within a certain test area in Flagstaff, Arizona. The capital carrying costs of the program will be recovered through the RES until such time as these costs are recovered in base rates. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">On July&#160;1, 2010, APS filed its annual RES implementation plan, covering the 2011-2015 timeframe and requesting 2011 RES funding of $96&#160;million. The 2011 Plan addressed enhancements to the residential distributed energy incentive program based on high customer participation, among other things. On October&#160;13, 2010, APS filed an adjusted RES implementation plan to reflect the following items, among others: 1) increased clarity relating to customer project in-service dates and related budget revisions; 2) AZ Sun Program updates; and 3) the addition of 10 MW of biomass capacity. On December&#160;10, 2010, the ACC approved the 2011 Plan and associated funding request. In January&#160;2011, the ACC voted to reconsider four aspects of the approved 2011 Plan, including: (a)&#160;approval to proceed with a feed-in tariff filing; (b)&#160;approval for APS to participate in the ownership of distributed energy facilities in the Schools and Government program; (c)&#160;denial of a Rapid Reservation program that allows customers to receive priority in the incentive reservation process in exchange for receipt of a reduced incentive amount; and (d)&#160;allocation of the budget among various programs and studies. Hearings were held on January&#160;24, 2011 and January&#160;28, 2011. The ACC amended its original decision that approved the 2011 Plan as follows: the ACC (a)&#160;reversed its approval of a feed-in tariff program; (b)&#160;restricted APS&#8217;s ownership of facilities to only economically challenged, rural schools and only after a school has received a bid from a third-party solar installer; (c)&#160;approved the Rapid Reservation program; and (d)&#160;maintained the original approved budget with some timing modifications. </div> <!-- Folio --> <!-- /Folio --> </div> <!-- PAGEBREAK --> <div style="font-family: 'Times New Roman',Times,serif; margin-left: 0in; "> <div align="center" style="font-size: 10pt; margin-top: 0pt"> <b> </b> </div> <div align="center" style="font-size: 10pt"> <b> </b> </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%"><b><i>Demand-Side Management Adjustor Charge (&#8220;DSMAC&#8221;). </i></b>The 2009 retail rate case settlement agreement requires APS to submit an annual Energy Efficiency Implementation Plan for review by and approval of the ACC. On July&#160;15, 2009, APS filed its initial Energy Efficiency Implementation Plan, requesting approval by the ACC of programs and program elements for which APS had estimated a budget in the amount of $50&#160;million for 2010. APS received ACC approval of all of its proposed programs and implemented the new DSMAC on March&#160;1, 2010. A surcharge was added to customer bills in order to recover these estimated amounts for use on certain demand-side management programs. The surcharge allows for the recovery of energy efficiency expenses and any earned incentives. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">The ACC approved recovery of all 2009 program costs plus incentives. The change from program cost recovery on a historical basis to recovery on a concurrent basis, as authorized in the settlement agreement, resulted in this one-time need to address two years (2009 and 2010) of cost recovery. As requested by APS, 2009 program cost recovery is to be spread over a three-year period. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">On June&#160;1, 2010, APS filed its 2011 Energy Efficiency Implementation Plan. In order to meet the energy efficiency goal for 2011 established by the settlement agreement of annual energy savings of 1.25%, expressed as a percent of total energy resources to meet retail load, APS proposed a total budget for 2011 of $79&#160;million. On February&#160;17, 2011, a total budget for 2011 of $80&#160;million was approved and when added to the amortization of 2009 costs discussed above less the $10&#160;million already being recovered in general rates, the DSMAC would recover approximately $75&#160;million over a twelve month period beginning March&#160;1, 2011.

A large portion of the rate represents charges for transmission services to serve APS&#8217;s retail customers (&#8220;Retail Transmission Charges&#8221;). In order to recover the Retail Transmission Charges, APS must file an application with, and obtain approval from, the ACC to reflect changes in Retail Transmission Charges through the TCA. </div> <!-- Folio --> <!-- /Folio --> </div> <!-- PAGEBREAK --> <div style="font-family: 'Times New Roman',Times,serif; margin-left: 0in; "> <div align="center" style="font-size: 10pt; margin-top: 0pt"> <b> </b> </div> <div align="center" style="font-size: 10pt"> <b> </b> </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">The formula rate is updated each year effective June 1 on the basis of APS&#8217;s actual cost of service, as disclosed in APS&#8217;s FERC Form&#160;1 report for the previous fiscal year. Items to be updated include actual capital expenditures made as compared with previous projections, transmission revenue credits and other items. The resolution of proposed adjustments can result in significant volatility in the revenues to be collected. APS reviews the proposed formula rate filing amounts with the ACC staff. Any items or adjustments which are not agreed to by APS and the ACC staff can remain in dispute until settled or litigated at FERC. Settlement or litigated resolution of disputed issues could require an extended period of time and have a significant effect on the Retail Transmission Charge because any adjustment, though applied prospectively, may be calculated to account for previously over-collected amounts. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">Effective June&#160;1, 2010, APS&#8217;s annual wholesale transmission rates for all users of its transmission system were reduced by approximately $12&#160;million in accordance with the FERC-approved formula as a result of lower costs reflected in the formula. Approximately $10&#160;million of this revenue reduction relates to transmission services used for APS&#8217;s retail customers. On May&#160;20, 2010, APS filed with the ACC an application for the related reduction of its TCA rate.

As a result of this settlement, net uncertain tax positions decreased $62&#160;million, including approximately $3 million which decreased our effective tax rate. Additionally, the settlement resulted in the recognition of net interest benefits of approximately $4&#160;million through the effective tax rate. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">Included in the balances of unrecognized tax benefits at December&#160;31, 2010, 2009 and 2008 were approximately $7&#160;million, $16&#160;million and $16&#160;million, respectively, of tax positions that, if recognized, would decrease our effective tax rate. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">As of the balance sheet date, the tax year ended December&#160;31, 2008 and all subsequent tax years remain subject to examination by the IRS. With few exceptions, we are no longer subject to state income tax examinations by tax authorities for years before 1999.

The amount of interest recognized in the Consolidated Statement of Income related to unrecognized tax benefits was a pre-tax benefit of $2&#160;million for 2010, a pre-tax expense of $2&#160;million for 2009 and a pre-tax benefit of $51&#160;million for 2008. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">The total amount of accrued liabilities for interest recognized in the consolidated Balance Sheets related to unrecognized tax benefits was $6&#160;million as of December&#160;31, 2010, $8&#160;million as of December&#160;31, 2009 and $6&#160;million as of December&#160;31, 2008. To the extent that matters are settled favorably, this amount could reverse and decrease our effective tax rate.

Pinnacle West and APS comply with this covenant and each anticipates it will continue to meet this and other significant covenant requirements. For both Pinnacle West and APS, this covenant requires that the ratio of consolidated debt to total consolidated capitalization not exceed 65%. At December&#160;31, 2010, the ratio was approximately 49% for Pinnacle West and 46% for APS. 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 and could cross-default other debt. See further discussion of &#8220;cross-default&#8221; provisions below. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">Neither Pinnacle West&#8217;s nor APS&#8217;s financing agreements contain &#8220;rating triggers&#8221; that would result in an acceleration of the required interest and principal payments in the event of a rating downgrade.

All of APS&#8217;s bank agreements contain cross-default provisions that would result in defaults and the potential acceleration of payment under these bank agreements if APS were to default under certain other material agreements. Pinnacle West and APS do not have a material adverse change restriction for credit facility borrowings. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">An existing ACC order requires APS to maintain a common equity ratio of at least 40%. As defined in the ACC order, the common equity ratio is total shareholder equity divided by the sum of total shareholder equity and long-term debt, including current maturities of long-term debt. At December&#160;31, 2010, APS&#8217;s common equity ratio, as defined, was 53%. Its total shareholder equity was approximately $3.8&#160;billion, and total capitalization was approximately $7.2&#160;billion. APS would be prohibited from paying dividends if the payment would reduce its total shareholder equity below approximately $2.9&#160;billion, assuming APS&#8217;s total capitalization remains the same.

All new employees participate in the account balance plan. Defined benefit plans specify the amount of benefits a plan participant is to receive using information about the participant. The pension plan covers nearly all employees. The supplemental excess benefit retirement plan covers officers of the Company and highly compensated employees designated for participation by the Board of Directors. Our employees do not contribute to the plans. Generally, we calculate the benefits based on age, years of service and pay. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">We also sponsor other postretirement benefits for the employees of Pinnacle West and our subsidiaries. We provide medical and life insurance benefits to retired employees. Employees must retire to become eligible for these retirement benefits, which are based on years of service and age. For the medical insurance plans, retirees make contributions to cover a portion of the plan costs. For the life insurance plan, retirees do not make contributions. We retain the right to change or eliminate these benefits. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">Pinnacle West uses a December&#160;31 measurement date each year for its pension and other postretirement benefit plans. The market-related value of our plan assets is their fair value at the measurement date. See Note 14 for discussion of how fair values are determined. Due to subjective and complex judgments, which may be required in determining fair values, actual results could differ from the results estimated through the application of these methods. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">A significant portion of the changes in the actuarial gains and losses of our pension and postretirement plans is attributable to APS and therefore is recoverable in rates. Accordingly, these changes are recorded as a regulatory asset. In its 2009 retail rate case settlement, APS received approval to defer a portion of pension and other postretirement benefit cost increases incurred in 2011 and 2012. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">On March&#160;23, 2010, the President signed into law comprehensive health care reform legislation under the Patient Protection and Affordable Care Act (the &#8220;Act&#8221;). One feature of the Act is the elimination of the tax deduction for prescription drug costs that are reimbursed as part of the Medicare Part&#160;D subsidy. Although this tax increase does not take effect until 2013, we are required to recognize the full accounting impact in our financial statements in the period in which the Act is signed. In accordance with accounting for regulated companies, the loss of this deduction is substantially offset by a regulatory asset that will be recovered through future electric revenues. In the first quarter of 2010, Pinnacle West charged regulatory assets and liabilities for a total of $42&#160;million, with a corresponding increase in accumulated deferred income tax liabilities, to reflect the impact of this change in tax law. </div> <!-- Folio --> <!-- /Folio --> </div> <!-- PAGEBREAK --> <div style="font-family: 'Times New Roman',Times,serif;

The investment policy&#8217;s overall strategy is to achieve an adequate level of trust assets relative to the benefit obligation. To achieve this objective, the plans&#8217; investment policies provide for a mix of investments in long-term fixed income assets and return-generating assets. Long-term fixed income assets are designed to offset changes in benefit obligations due to changes in discount rates and inflation. Return-generating assets are intended to provide a reasonable long-term rate of investment return with a prudent level of volatility. The determination of total allocation between return-generating and long-term fixed income assets is reviewed on at least an annual basis. Other investment strategies include the prohibition of investments in Pinnacle West securities and the external management of the plans&#8217; assets. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">Long-term fixed income assets consist primarily of fixed income debt securities issued by the U.S. Treasury, other government agencies, and corporations. Long-term fixed income assets may also include interest rate swaps, U.S. Treasury futures and other instruments. The investment policy does not provide for a specific mix of long-term fixed income assets, but does require the average credit rating of such assets to be considered upper medium grade or above. The 2010&#160;year-end long-term fixed income asset strategy focused on investments in corporate bonds of primarily investment-grade U.S. issuers and long-term treasuries, with total long-term fixed income assets representing 41% of total pension plan assets and 39% of other benefit plans assets. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">Return-generating assets in the pension plan and other benefit plans target a mix of approximately 64% U.S. equities, 27% international equities, and 9% alternative investments. The 2010&#160;year-end U.S. equity holdings were invested primarily in large-cap companies in diverse industries. International equities include investments in emerging and developing markets. Return-generating assets also include investments in securities through commingled funds in common and collective trusts. Alternative investments primarily include investments in real estate. The 2010&#160;year-end return-generating assets represented 59% of total pension plan assets and 61% of other benefit plans assets. </div> <!-- Folio --> <!-- /Folio --> </div> <!-- PAGEBREAK --> <div style="font-family: 'Times New Roman',Times,serif; margin-left: 0in; "> <div align="center" style="font-size: 10pt; margin-top: 0pt"> <b> </b> </div> <div align="center" style="font-size: 10pt"> <b> </b> </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">See Note 14 for a discussion on the fair value hierarchy and how fair value methodologies are applied.

APS&#8217;s share is approximately 98% of both plans. </div> <!-- Folio --> <!-- /Folio --> </div> <!-- PAGEBREAK --> <div style="font-family: 'Times New Roman',Times,serif; margin-left: 0in; "> <div align="center" style="font-size: 10pt; margin-top: 0pt"> <b> </b> </div> <div align="center" style="font-size: 10pt"> <b> </b> </div> <div align="left" style="font-size: 10pt; margin-top: 10pt"><b>Estimated Future Benefit Payments</b> </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">Benefit payments, which reflect estimated future employee service, for the next five years and the succeeding five years thereafter are estimated to be as follows (dollars in thousands): </div> <div align="center"> <table style="font-size: 10pt; text-align: left" cellspacing="0" border="0" cellpadding="0" width="100%"> <!-- Begin Table Head --> <tr valign="bottom"> <td width="72%">&#160;</td> <td width="3%">&#160;</td> <td width="1%">&#160;</td> <td width="9%">&#160;</td> <td width="1%">&#160;</td> <td width="3%">&#160;</td> <td width="1%">&#160;</td> <td width="9%">&#160;</td> <td width="1%">&#160;</td> </tr> <tr style="font-size: 10pt" valign="bottom"> <td nowrap="nowrap" align="left" style="border-bottom: 1px solid #000000">Year</td> <td>&#160;</td> <td nowrap="nowrap" align="center" colspan="2" style="border-bottom: 1px solid #000000">Pension</td> <td>&#160;</td> <td>&#160;</td> <td nowrap="nowrap" align="center" colspan="2" style="border-bottom: 1px solid #000000">Other Benefits (a)</td> <td>&#160;</td> </tr> <!-- End Table Head --> <!-- Begin Table Body --> <tr valign="bottom" style="background: #cceeff"> <td> <div style="margin-left:15px; text-indent:-15px">2011 </div></td> <td>&#160;</td> <td align="left">$</td> <td align="right">106,556</td> <td>&#160;</td> <td>&#160;</td> <td align="left">$</td> <td align="right">23,197</td> <td>&#160;</td> </tr> <tr valign="bottom"> <td> <div style="margin-left:15px; text-indent:-15px">2012 </div></td> <td>&#160;</td> <td>&#160;</td> <td align="right">116,615</td> <td>&#160;</td> <td>&#160;</td> <td>&#160;</td> <td align="right">25,713</td> <td>&#160;</td> </tr> <tr valign="bottom" style="background: #cceeff"> <td> <div style="margin-left:15px; text-indent:-15px">2013 </div></td> <td>&#160;</td> <td>&#160;</td> <td align="right">129,031</td> <td>&#160;</td> <td>&#160;</td> <td>&#160;</td> <td align="right">28,619</td> <td>&#160;</td> </tr> <tr valign="bottom"> <td> <div style="margin-left:15px; text-indent:-15px">2014 </div></td> <td>&#160;</td> <td>&#160;</td> <td align="right">141,815</td> <td>&#160;</td> <td>&#160;</td> <td>&#160;</td> <td align="right">31,484</td> <td>&#160;</td> </tr> <tr valign="bottom" style="background: #cceeff"> <td> <div style="margin-left:15px; text-indent:-15px">2015 </div></td> <td>&#160;</td> <td>&#160;</td> <td align="right">154,185</td> <td>&#160;</td> <td>&#160;</td> <td>&#160;</td> <td align="right">34,176</td> <td>&#160;</td> </tr> <tr valign="bottom"> <td> <div style="margin-left:15px; text-indent:-15px">Years 2016-2020 </div></td> <td>&#160;</td> <td>&#160;</td> <td align="right">972,338</td> <td>&#160;</td> <td>&#160;</td> <td>&#160;</td> <td align="right">216,736</td> <td>&#160;</td> </tr> <!-- End Table Body --> </table> </div> <table width="100%" border="0" cellpadding="0" cellspacing="0" style="font-size: 10pt; text-align: left"> <tr style="font-size: 6pt"> <td width="3%">&#160;</td> <td width="1%">&#160;</td> <td width="96%">&#160;</td> </tr> <tr valign="top"> <td nowrap="nowrap" align="left">(a)</td> <td>&#160;</td> <td>The expected future other benefit payments take into account the Medicare Part D subsidy.</td> </tr> </table> <div align="left" style="font-size: 10pt; margin-top: 10pt"><b>Employee Savings Plan Benefits</b> </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">Pinnacle West sponsors a defined contribution savings plan for eligible employees of Pinnacle West and its subsidiaries. In 2010, costs related to APS&#8217;s employees represented 98% of the total cost of this plan. In a defined contribution savings plan, the benefits a participant receives result from regular contributions participants make to their own individual account, the Company&#8217;s matching contributions and earnings or losses on their investments. Under this plan, the Company matches a percentage of the participants&#8217; contributions in cash which is then invested in the same investment mix as participants elect to invest their own future contributions. Pinnacle West recorded expenses for this plan of approximately $9&#160;million for 2010, $9&#160;million for 2009 and $8 million for 2008. </div> </div> <span></span> </td> </tr> </table> <div style="display: none;"> <table border="0" cellpadding="0" cellspacing="0" class="authRefData" style="display: none;" id="defref_us-gaap_GeneralDiscussionOfPensionAndOtherPostretirementBenefitsAbstract"> <tr><td class="hide"><a style="color: white;" href="javascript:void(0);" onclick="top.Show.hideAR();">X</a></td></tr> <tr><td><div class="body" style="padding: 2px;"> <a href="javascript:void(0);" onclick="top.Show.toggleNext( this );">- References</a><div><p>No definition available.</p></div> <a href="javascript:void(0);" onclick="top.Show.toggleNext( this );">+ Details</a><div style="display: none;"><table border="0" cellpadding="0" cellspacing="0"> <tr> <td><strong> Name:</strong></td> <td style="white-space:nowrap;">us-gaap_GeneralDiscussionOfPensionAndOtherPostretirementBenefitsAbstract</td> </tr> <tr> <td style="padding-right: 4px;white-space:nowrap;"><strong> Namespace Prefix:</strong></td> <td>us-gaap_</td> </tr> <tr> <td><strong> Data Type:</strong></td> <td>xbrli:stringItemType</td> </tr> <tr> <td><strong> Balance Type:</strong></td> <td>na</td> </tr> <tr> <td><strong> Period Type:</strong></td> <td>duration</td> </tr> </table></div> </div></td></tr> </table> <table border="0" cellpadding="0" cellspacing="0" class="authRefData" style="display: none;" id="defref_us-gaap_PensionAndOtherPostretirementBenefitsDisclosureTextBlock"> <tr><td class="hide"><a style="color: white;" href="javascript:void(0);" onclick="top.Show.hideAR();">X</a></td></tr> <tr><td><div class="body" style="padding: 2px;"> <a href="javascript:void(0);" onclick="top.Show.toggleNext( this );">- References</a><div><p>No definition available.</p></div> <a href="javascript:void(0);" onclick="top.Show.toggleNext( this );">+ Details</a><div style="display: none;"><table border="0" cellpadding="0" cellspacing="0"> <tr> <td><strong> Name:</strong></td> <td style="white-space:nowrap;">us-gaap_PensionAndOtherPostretirementBenefitsDisclosureTextBlock</td> </tr> <tr> <td style="padding-right: 4px;white-space:nowrap;"><strong> Namespace Prefix:</strong></td> <td>us-gaap_</td> </tr> <tr> <td><strong> Data Type:</strong></td> <td>us-types:textBlockItemType</td> </tr> <tr> <td><strong> Balance Type:</strong></td> <td>na</td> </tr> <tr> <td><strong> Period Type:</strong></td> <td>duration</td> </tr> </table></div> </div></td></tr> </table> </div> </body> </html> </div><div id="xbrl_R17" style="display:none"><html> <head> <title></title></link> </head> <body> <span style="display: none;">v3.19.3</span><table class="report" border="0" cellspacing="2" id="idm140525593170440"> <tr> <th class="tl" colspan="1" rowspan="2"><div style="width: 200px;"><strong>Leases<br></strong></div></th> <th class="th" colspan="1">12 Months Ended</th> </tr> <tr><th class="th"><div>Dec. 31, 2010</div></th></tr> <tr class="re"> <td class="pl " style="border-bottom: 0px;" valign="top"><a class="a" href="javascript:void(0);" onclick="top.Show.showAR( this, 'defref_us-gaap_LeasesAbstract', window );"><strong>Leases [Abstract]</strong></a></td> <td class="text">&#160;<span></span> </td> </tr> <tr class="ro"> <td class="pl " style="border-bottom: 0px;" valign="top"><a class="a" href="javascript:void(0);" onclick="top.Show.showAR( this, 'defref_us-gaap_OperatingLeasesOfLesseeDisclosureTextBlock', window );">Leases</a></td> <td class="text"><!--DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" --> <!-- Begin Block Tagged Note 9 - us-gaap:OperatingLeasesOfLesseeDisclosureTextBlock--> <div style="font-family: 'Times New Roman',Times,serif; margin-left: 0in; "> <div align="left" style="font-size: 10pt; margin-top: 10pt"><b>9.

Prior to January&#160;1, 2010 the arrangements were accounted for as operating leases. On January&#160;1, 2010, due to the adoption of amended accounting guidance related to VIE&#8217;s these agreements were deemed variable interests and consolidated. We adopted this accounting change using retrospective application and have adjusted prior periods presented. Consolidation of the lessor trust entities eliminates the lease accounting we previously reported and results in changes in our consolidated assets, debt, equity, and net income. The above disclosures exclude the impacts of these transactions, as lease accounting for these agreements is eliminated upon consolidation.

As required by the Price Anderson Nuclear Industries Indemnity Act, Palo Verde maintains the maximum available nuclear liability insurance in the amount of $375 million, which is provided by commercial insurance carriers. The remaining balance of $12.2 billion is provided through a mandatory industry wide retrospective assessment program. If losses at any nuclear power plant covered by the program 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 $118&#160;million, subject to an annual limit of $18&#160;million per incident, to be periodically adjusted for inflation. Based on APS&#8217;s interest in the three Palo Verde units, APS&#8217;s maximum potential assessment per incident for all three units is approximately $103&#160;million, with an annual payment limitation of approximately $15&#160;million. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">The Palo Verde participants maintain &#8220;all risk&#8221; (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 accidental outage of any of the three units. The property damage, decontamination, and replacement power coverages are provided by Nuclear Electric Insurance Limited (&#8220;NEIL&#8221;). APS is subject to retrospective assessments under all NEIL policies if NEIL&#8217;s losses in any policy year exceed accumulated funds. The maximum amount APS could incur under the current NEIL policies totals approximately $16&#160;million for each retrospective assessment declared by NEIL&#8217;s Board of Directors due to losses. In addition, NEIL policies contain rating triggers that would result in APS providing approximately $44&#160;million of collateral assurance within 20 business days of a rating downgrade to non-investment grade. The insurance coverage discussed in this and the previous paragraph is subject to certain policy conditions and exclusions. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt"><b>Fuel and Purchased Power Commitments and Purchase Obligations</b> </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">APS is party to purchase obligations and various fuel and purchased power contracts with terms expiring between 2011 and 2042 that include required purchase provisions.

In addition, on September&#160;23, 2009, APS agreed with the EPA and one other PRP to voluntarily assist with the funding and management of the site-wide groundwater remedial investigation and feasibility study work plan. We estimate that our costs related to this investigation and study will be approximately $1&#160;million, which is reserved as a liability on our financial statements. We anticipate incurring additional expenditures in the future, but because the overall investigation is not complete and ultimate remediation requirements are not yet finalized, at the present time we cannot accurately estimate our total expenditures. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt"><b>Landlord Bankruptcy</b> </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">On April&#160;16, 2009, the landlord for our corporate headquarters building announced that it is seeking relief under Chapter&#160;11 of the United States Bankruptcy Code. We currently have several assets on our books related to our landlord, the most significant of which is an asset related to levelized rent payments for the building of approximately $71&#160;million. This amount will continue to increase to approximately $93&#160;million as a result of the lease terms until 2015, when this amount will begin to decrease over the remaining life of the lease. In November&#160;2010, our landlord exited bankruptcy and our leases were assumed and reinstated.

Asset Retirement Obligations</b> </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">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&#8217;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. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">Some of APS&#8217;s 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 to continue. As a result, APS cannot reasonably estimate the fair value of the asset retirement obligation related to such distribution and transmission assets. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">Additionally, APS has aquifer protection permits for some of its generation sites that require the closure of certain facilities at those sites.

Fair Value Measurements</b> </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">We disclose the fair value of certain assets and liabilities according to a fair value hierarchy. This hierarchy ranks the quality and reliability of the inputs used to determine fair values, which are then classified and disclosed in one of three categories. The three levels of the fair value hierarchy are: </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; margin-left: 4%">Level 1 &#8212; Quoted prices in active markets for identical assets or liabilities. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide information on an ongoing basis. This category includes derivative instruments that are exchange-traded such as futures, cash equivalents invested in exchange-traded money market funds, exchange-traded equities, and nuclear decommissioning trust investments in Treasury securities. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; margin-left: 4%">Level 2 &#8212; Quoted prices in active markets for similar assets or liabilities; quoted prices in markets that are not active; and model-derived valuations whose inputs are observable. This category includes nonexchange-traded contracts such as forwards, options, and swaps. This category also includes investments, in common and commingled funds that are redeemable and valued based on the funds&#8217; net asset values. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; margin-left: 4%">Level 3 &#8212; Model-derived valuations with significant unobservable inputs that are supported by little or no market activity. Instruments in this category include long-dated derivative transactions where models are required due to the length of the transaction, options, transactions in locations where observable market data does not exist, and common and collective trusts with significant restrictions on our ability to transact in the fund. The valuation models we employ utilize spot prices, forward prices, historical market data and other factors to forecast future prices. The primary valuation technique we use to calculate the fair value of contracts where price quotes are not available is based on the extrapolation of forward pricing curves using observable market data for more liquid delivery points in the same region and actual transactions at the more illiquid delivery points. </div> <!-- Folio --> <!-- /Folio --> </div> <!-- PAGEBREAK --> <div style="font-family: 'Times New Roman',Times,serif; margin-left: 0in; "> <div align="center" style="font-size: 10pt; margin-top: 0pt"> <b> </b> </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. We maximize the use of observable inputs and minimize the use of unobservable inputs. If market data is not readily available, inputs may reflect our own assumptions about the inputs market participants would use. Our assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy levels. Thus, a valuation may be classified in Level 3 even though the valuation may include significant inputs that are readily observable. We assess whether a market is active by obtaining observable broker quotes, reviewing actual market transactions, and assessing the volume of transactions. We consider broker quotes observable inputs when the quote is binding on the broker, we can validate the quote with market transactions, or we can determine that the inputs the broker used to arrive at the quoted price are observable. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt"><b>Recurring Fair Value Measurements</b> </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">We apply recurring fair value measurements to derivative instruments, nuclear decommissioning trusts, certain cash equivalents and plan assets held in our retirement and other benefit plans (see Note 8). </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%"><b><i>Cash Equivalents</i></b> </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">Cash equivalents represent short-term investments in exchange-traded money market funds that are valued using quoted prices in active markets. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%"><b><i>Risk Management Activities</i></b> </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">Exchange-traded contracts are valued using quoted prices in active markets. For non-exchange traded contracts, we calculate fair market value based on the average of the bid and offer price, discounted to reflect net present value. We maintain certain valuation adjustments for a number of risks associated with the valuation of future commitments. These include valuation adjustments for liquidity and credit risks based on the financial condition of counterparties. The liquidity valuation adjustment represents the cost that would be incurred if all unmatched positions were closed-out or hedged. </div> <!-- Folio --> <!-- /Folio --> </div> <!-- PAGEBREAK --> <div style="font-family: 'Times New Roman',Times,serif; margin-left: 0in; "> <div align="center" style="font-size: 10pt; margin-top: 0pt"> <b> </b> </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">The credit valuation adjustment represents estimated credit losses on our overall exposure to counterparties, taking into account netting arrangements, expected default experience for the credit rating of the counterparties and the overall diversification of the portfolio. Counterparties in the portfolio consist principally of major energy companies, municipalities, local distribution companies and financial institutions. We maintain credit policies that management believes minimize overall credit risk. Determination of the credit quality of counterparties is based upon a number of factors, including credit ratings, financial condition, project economics and collateral requirements. When applicable, we employ standardized agreements that allow for the netting of positive and negative exposures associated with a single counterparty. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">Some of our derivative instrument transactions are valued based on unobservable inputs due to the long-term nature of contracts or the unique location of the transactions. Our long-dated energy transactions consist of observable valuations for the near term portion and unobservable valuations for the long-term portions of the transaction. When the unobservable portion is significant to the overall valuation of the transaction, the entire transaction is classified as Level 3. Our classification of instruments as Level 3 is primarily reflective of the long-term nature of our energy transactions, and is not reflective of material inactive markets. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%"><b><i>Nuclear Decommissioning Trust</i></b> </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">The nuclear decommissioning trust invests in fixed income securities directly and equity securities indirectly through commingled funds. The commingled equity funds are valued based on the fund&#8217;s net asset value (&#8220;NAV&#8221;) and are classified within Level 2. We may transact in the fund on a semi-monthly basis. Our trustee provides valuation of our nuclear decommissioning trust assets by using pricing services to determine fair market value. We assess these valuations and verify that pricing can be supported by actual recent market transactions. The trust fund investments have been established to satisfy APS&#8217;s nuclear decommissioning obligations. </div> <!-- Folio --> <!-- /Folio --> </div> <!-- PAGEBREAK --> <div style="font-family: 'Times New Roman',Times,serif;

In 2010, non-officer members of the Board of Directors were given the option to elect to receive a stock grant, or to defer receipt and receive restricted stock units in lieu of the stock grant. The 2010 stock grants and deferred restricted stock units were issued under the 2007 Plan. The election to receive a stock grant or to defer, and the related elections were made on or before December&#160;31, 2009. Participants had to elect to receive their deferred grant as of the last business day of the month following the month in which they separate service from the Board of Directors, or as of a date specified by them in 2011 or later. The deferral has the election to receive payment in either 50% cash and 50% fully transferable shares of stock, or 100% in fully transferable shares of stock, in exchange for each restricted stock unit. Each restricted stock unit payable in cash represents the right to receive a cash payment equal to the fair market value of one share of Pinnacle West&#8217;s common stock.

We manage risks associated with these market fluctuations by utilizing various derivative instruments, including futures, forwards, options and swaps. As part of our overall risk management program, we may use such instruments to hedge purchases and sales of electricity, fuels, and emissions allowances and credits. Derivative instruments that are designated as cash flow hedges are used to limit our exposure to cash flow variability on forecasted transactions. The changes in market value of such contracts have a high correlation to price changes in the hedged transactions. We may also invest in derivative instruments for trading purposes; however, for the year ended December 31, 2010, there was no material trading activity. </div> <!-- Folio --> <!-- /Folio --> </div> <!-- PAGEBREAK --> <div style="font-family: 'Times New Roman',Times,serif; margin-left: 0in; "> <div align="center" style="font-size: 10pt; margin-top: 0pt"> <b> </b> </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">Our derivative instruments are accounted for at fair value; see Note 14 for a discussion of fair value measurements. Derivative instruments for the physical delivery of purchase and sale quantities transacted in the normal course of business qualify for the normal purchase and sales scope exception and are accounted for under the accrual method of accounting. Due to the scope exception, these derivative instruments are excluded from our derivative instrument discussion and disclosures below. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">We also enter into derivative instruments for economic hedging purposes. While we believe the economic hedges mitigate exposure to fluctuations in commodity prices, some of these instruments may not meet the specific hedge accounting requirements and are not designated as accounting hedges. Economic hedges not designated as accounting hedges are recorded at fair value on our balance sheet with changes in fair value recognized in the statement of income as incurred. These instruments are included in the &#8220;non-designated hedges&#8221; discussion and disclosure below. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">Hedge effectiveness is the degree to which the derivative instrument contract and the hedged item are correlated and is measured based on the relative changes in fair value of the derivative instrument contract and the hedged item over time. We assess hedge effectiveness both at inception and on a continuing basis. These assessments exclude the time value of certain options. For accounting hedges that are deemed an effective hedge, the effective portion of the gain or loss on the derivative instrument is reported as a component of accumulated other comprehensive income (&#8220;AOCI&#8221;) and reclassified into earnings in the same period during which the hedged transaction affects earnings. We recognize in current earnings, subject to the PSA, the gains and losses representing hedge ineffectiveness, and the gains and losses on any hedge components which are excluded from our effectiveness assessment. As of December&#160;31, 2010, we hedged the majority of certain exposures to the price variability of commodities for a maximum of 39&#160;months. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">In the electricity business, some contracts to purchase energy are netted against other contracts to sell energy. This is called &#8220;book-out&#8221; and usually occurs in contracts that have the same terms (quantities and delivery points) and for which power does not flow. We net these book-outs, which reduces both revenues and fuel and purchased power costs in our Consolidated Statements of Income, but this does not impact our financial condition, net income or cash flows. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">For its regulated operations, APS defers for future rate treatment approximately 90% of unrealized gains and losses on certain derivatives pursuant to the PSA mechanism that would otherwise be recognized in income. Realized gains and losses on derivatives are deferred in accordance with the PSA to the extent the amounts are above or below the Base Fuel Rate (see Note 3). Gains and losses from derivatives in the following tables represent the amounts reflected in income before the effect of PSA deferrals. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt;

We have risk management contracts with many counterparties, including two counterparties for which our exposure represents approximately 44% of Pinnacle West&#8217;s $113&#160;million of risk management assets as of December&#160;31, 2010. This exposure relates to long-term traditional wholesale contracts with counterparties that have very high credit quality. Our risk management process assesses and monitors the financial exposure of all counterparties. Despite the fact that the great majority of trading counterparties&#8217; debt is rated as investment grade by the credit rating agencies, 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 financial institutions, 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. To manage credit risk, we employ collateral requirements and standardized agreements that allow for the netting of positive and negative exposures associated with a single counterparty. Valuation adjustments are established representing our estimated credit losses on our overall exposure to counterparties. </div> <!-- Folio --> <!-- /Folio --> </div> <!-- PAGEBREAK --> <div style="font-family: 'Times New Roman',Times,serif; margin-left: 0in; "> <div align="center" style="font-size: 10pt; margin-top: 0pt"> <b> </b> </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">Certain of our derivative instrument contracts contain credit-risk-related contingent features including, among other things, investment grade credit rating provisions, credit-related cross default provisions, and adequate assurance provisions. Adequate assurance provisions allow a counterparty with reasonable grounds for uncertainty to demand additional collateral based on subjective events and/or conditions. The aggregate fair value of all derivative instruments with credit-risk-related contingent features that were in a liability position on December&#160;31, 2010 was $349&#160;million, for which we had posted collateral of $192&#160;million in the normal course of business. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">For those derivative instruments in a net liability position, with investment grade credit contingencies, the counterparties could demand additional collateral if our debt credit rating were to fall below investment grade (below BBB- for Standard &#038; Poor&#8217;s or Fitch or Baa3 for Moody&#8217;s), which would be a violation of the credit rating provisions. If the investment grade contingent features underlying these agreements had been triggered on December&#160;31, 2010, after off-setting asset positions under master netting arrangements we would have been required to post approximately an additional $125&#160;million of collateral to our counterparties; this amount includes those contracts which qualify for scope exceptions, which are excluded from the derivative details in the above footnote. We also have energy related non-derivative instrument contracts with investment grade credit-related contingent features which could also require us to post additional collateral of approximately $205&#160;million if our debt credit ratings were to fall below investment grade. </div> </div> <span></span> </td> </tr> </table> <div style="display: none;"> <table border="0" cellpadding="0" cellspacing="0" class="authRefData" style="display: none;" id="defref_us-gaap_DerivativeInstrumentsAndHedgesAbstract"> <tr><td class="hide"><a style="color: white;" href="javascript:void(0);" onclick="top.Show.hideAR();">X</a></td></tr> <tr><td><div class="body" style="padding: 2px;"> <a href="javascript:void(0);" onclick="top.Show.toggleNext( this );">- References</a><div><p>No definition available.</p></div> <a href="javascript:void(0);" onclick="top.Show.toggleNext( this );">+ Details</a><div style="display: none;"><table border="0" cellpadding="0" cellspacing="0"> <tr> <td><strong> Name:</strong></td> <td style="white-space:nowrap;">us-gaap_DerivativeInstrumentsAndHedgesAbstract</td> </tr> <tr> <td style="padding-right: 4px;white-space:nowrap;"><strong> Namespace Prefix:</strong></td> <td>us-gaap_</td> </tr> <tr> <td><strong> Data Type:</strong></td> <td>xbrli:stringItemType</td> </tr> <tr> <td><strong> Balance Type:</strong></td> <td>na</td> </tr> <tr> <td><strong> Period Type:</strong></td> <td>duration</td> </tr> </table></div> </div></td></tr> </table> <table border="0" cellpadding="0" cellspacing="0" class="authRefData" style="display: none;" id="defref_us-gaap_DerivativeInstrumentsAndHedgingActivitiesDisclosureTextBlock"> <tr><td class="hide"><a style="color: white;" href="javascript:void(0);" onclick="top.Show.hideAR();">X</a></td></tr> <tr><td><div class="body" style="padding: 2px;"> <a href="javascript:void(0);" onclick="top.Show.toggleNext( this );">- References</a><div><p>No definition available.</p></div> <a href="javascript:void(0);" onclick="top.Show.toggleNext( this );">+ Details</a><div style="display: none;"><table border="0" cellpadding="0" cellspacing="0"> <tr> <td><strong> Name:</strong></td> <td style="white-space:nowrap;">us-gaap_DerivativeInstrumentsAndHedgingActivitiesDisclosureTextBlock</td> </tr> <tr> <td style="padding-right: 4px;white-space:nowrap;"><strong> Namespace Prefix:</strong></td> <td>us-gaap_</td> </tr> <tr> <td><strong> Data Type:</strong></td> <td>us-types:textBlockItemType</td> </tr> <tr> <td><strong> Balance Type:</strong></td> <td>na</td> </tr> <tr> <td><strong> Period Type:</strong></td> <td>duration</td> </tr> </table></div> </div></td></tr> </table> </div> </body> </html> </div><div id="xbrl_R27" style="display:none"><html> <head> <title></title></link> </head> <body> <span style="display: none;">v3.19.3</span><table class="report" border="0" cellspacing="2" id="idm140525550432184"> <tr> <th class="tl" colspan="1" rowspan="2"><div style="width: 200px;"><strong>Other Income and Other Expense<br></strong></div></th> <th class="th" colspan="1">12 Months Ended</th> </tr> <tr><th class="th"><div>Dec. 31, 2010</div></th></tr> <tr class="re"> <td class="pl " style="border-bottom: 0px;" valign="top"><a class="a" href="javascript:void(0);" onclick="top.Show.showAR( this, 'defref_us-gaap_NonoperatingIncomeExpenseAbstract', window );"><strong>Other Income and Other Expense [Abstract]</strong></a></td> <td class="text">&#160;<span></span> </td> </tr> <tr class="ro"> <td class="pl " style="border-bottom: 0px;" valign="top"><a class="a" href="javascript:void(0);" onclick="top.Show.showAR( this, 'defref_us-gaap_OtherIncomeAndOtherExpenseDisclosureTextBlock', window );">Other Income and Other Expense</a></td> <td class="text"><!--DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" --> <!-- Begin Block Tagged Note 19 - us-gaap:OtherIncomeAndOtherExpenseDisclosureTextBlock--> <div style="font-family: 'Times New Roman',Times,serif; margin-left: 0in; "> <div align="left" style="font-size: 10pt; margin-top: 10pt"><b>19.

The VIE lessor trusts are single-asset leasing entities. APS will pay approximately $49&#160;million per year for the years 2010 to 2015 related to these leases. The leases do not contain fixed price purchase options or residual value guarantees. However, the lease agreements include fixed rate renewal periods which may have a significant impact on the VIEs&#8217; economic performance. We have concluded that these fixed rate renewal periods may give APS the ability to utilize the asset for a significant portion of the asset&#8217;s economic life, and therefore provide APS with the power to direct activities of the VIEs that most significantly impact the VIEs&#8217; economic performance. In addition to the fixed rate renewal periods, our primary beneficiary analysis also considered that APS is the operating agent for Palo Verde, is obligated to decommission the leased assets and has fair value purchase options. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">Under the previous quantitative VIE consolidation model, APS was not considered the primary beneficiary of the lessor trusts, as APS did not absorb the majority of the entities&#8217; expected losses or did not receive a majority of the residual returns. Prior to January&#160;1, 2010 the arrangements were accounted for as operating leases. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">Consolidation of these VIEs eliminates the lease accounting we previously reported and results in changes in our consolidated assets, debt, equity, and net income. Assets of the VIEs are restricted and may only be used to settle the VIEs&#8217; debt obligations and for payment to the noncontrolling interest holders. Other than the VIEs&#8217; assets now reported on our consolidated financial statements, the creditors of the VIEs have no other recourse to the assets of APS or Pinnacle West, except in certain circumstances such as a default by APS under the lease. As a result of consolidation we have eliminated rent expense, and have recognized depreciation and interest expense, resulting in an increase in net income for 2010 of $20&#160;million entirely attributable to the noncontrolling interests. Income attributable to Pinnacle West shareholders remains the same. Consolidation of these VIEs also results in changes to our Consolidated Statements of Cash Flows, but does not impact net cash flows. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">Our Consolidated Balance Sheets at December&#160;31, 2010 and December&#160;31, 2009 include the following amounts relating to the VIEs (in millions): </div> <div align="center"> <table style="font-size: 10pt; text-align: left" cellspacing="0" border="0" cellpadding="0" width="100%"> <!-- Begin Table Head --> <tr valign="bottom"> <td width="72%">&#160;</td> <td width="3%">&#160;</td> <td width="1%">&#160;</td> <td width="9%">&#160;</td> <td width="1%">&#160;</td> <td width="3%">&#160;</td> <td width="1%">&#160;</td> <td width="9%">&#160;</td> <td width="1%">&#160;</td> </tr> <tr style="font-size: 10pt" valign="bottom"> <td>&#160;</td> <td>&#160;</td> <td nowrap="nowrap" align="center" colspan="2">December 31,</td> <td>&#160;</td> <td>&#160;</td> <td nowrap="nowrap" align="center" colspan="2">December 31,</td> <td>&#160;</td> </tr> <tr style="font-size: 10pt" valign="bottom"> <td>&#160;</td> <td>&#160;</td> <td nowrap="nowrap" align="center" colspan="2" style="border-bottom: 1px solid #000000">2010</td> <td>&#160;</td> <td>&#160;</td> <td nowrap="nowrap" align="center" colspan="2" style="border-bottom: 1px solid #000000">2009</td> <td>&#160;</td> </tr> <!-- End Table Head --> <!-- Begin Table Body --> <tr valign="bottom" style="background: #cceeff"> <td> <div style="margin-left:15px; text-indent:-15px">Property plant and equipment, net of accumulated depreciation </div></td> <td>&#160;</td> <td align="left">$</td> <td align="right">138</td> <td>&#160;</td> <td>&#160;</td> <td align="left">$</td> <td align="right">147</td> <td>&#160;</td> </tr> <tr valign="bottom"> <td> <div style="margin-left:15px; text-indent:-15px">Long-term debt including current maturities </div></td> <td>&#160;</td> <td>&#160;</td> <td align="right">126</td> <td>&#160;</td> <td>&#160;</td> <td>&#160;</td> <td align="right">152</td> <td>&#160;</td> </tr> <tr valign="bottom" style="background: #cceeff"> <td> <div style="margin-left:15px; text-indent:-15px">Equity- Noncontrolling interests </div></td> <td>&#160;</td> <td>&#160;</td> <td align="right">91</td> <td>&#160;</td> <td>&#160;</td> <td>&#160;</td> <td align="right">82</td> <td>&#160;</td> </tr> <!-- End Table Body --> </table> </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">For regulatory ratemaking purposes the leases continue to be treated as operating leases and, as a result, we have recorded a regulatory asset of $33&#160;million as of December&#160;31, 2010 and $31 million at December&#160;31, 2009. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">APS is exposed to losses relating to these lessor trust VIEs upon the occurrence of certain events that APS does not consider to be reasonably likely to occur.

If such an event had occurred as of December&#160;31, 2010, APS would have been required to pay the noncontrolling equity participants approximately $146&#160;million and assume $126&#160;million of debt.

Based on historical experience and evaluation of the specific indemnities, we do not believe that any material loss related to such indemnification provisions is likely. </div> <!-- Folio --> <!-- /Folio --> </div> <!-- PAGEBREAK --> <div style="font-family: 'Times New Roman',Times,serif; margin-left: 0in; "> <div align="center" style="font-size: 10pt; margin-top: 0pt"> <b> </b> </div> </div> <span></span> </td> </tr> </table> <div style="display: none;"> <table border="0" cellpadding="0" cellspacing="0" class="authRefData" style="display: none;" id="defref_pnw_GuaranteesAndSuretyBondsAbstract"> <tr><td class="hide"><a style="color: white;" href="javascript:void(0);" onclick="top.Show.hideAR();">X</a></td></tr> <tr><td><div class="body" style="padding: 2px;"> <a href="javascript:void(0);" onclick="top.Show.toggleNext( this );">- Definition</a><div><p>Guarantees and Surety Bonds.</p></div> <a href="javascript:void(0);" onclick="top.Show.toggleNext( this );">+ References</a><div style="display: none;"><p>No definition available.</p></div> <a href="javascript:void(0);" onclick="top.Show.toggleNext( this );">+ Details</a><div style="display: none;"><table border="0" cellpadding="0" cellspacing="0"> <tr> <td><strong> Name:</strong></td> <td style="white-space:nowrap;">pnw_GuaranteesAndSuretyBondsAbstract</td> </tr> <tr> <td style="padding-right: 4px;white-space:nowrap;"><strong> Namespace Prefix:</strong></td> <td>pnw_</td> </tr> <tr> <td><strong> Data Type:</strong></td> <td>xbrli:stringItemType</td> </tr> <tr> <td><strong> Balance Type:</strong></td> <td>na</td> </tr> <tr> <td><strong> Period Type:</strong></td> <td>duration</td> </tr> </table></div> </div></td></tr> </table> <table border="0" cellpadding="0" cellspacing="0" class="authRefData" style="display: none;" id="defref_us-gaap_ScheduleOfGuaranteeObligationsTextBlock"> <tr><td class="hide"><a style="color: white;" href="javascript:void(0);" onclick="top.Show.hideAR();">X</a></td></tr> <tr><td><div class="body" style="padding: 2px;"> <a href="javascript:void(0);" onclick="top.Show.toggleNext( this );">- References</a><div><p>No definition available.</p></div> <a href="javascript:void(0);" onclick="top.Show.toggleNext( this );">+ Details</a><div style="display: none;"><table border="0" cellpadding="0" cellspacing="0"> <tr> <td><strong> Name:</strong></td> <td style="white-space:nowrap;">us-gaap_ScheduleOfGuaranteeObligationsTextBlock</td> </tr> <tr> <td style="padding-right: 4px;white-space:nowrap;"><strong> Namespace Prefix:</strong></td> <td>us-gaap_</td> </tr> <tr> <td><strong> Data Type:</strong></td> <td>us-types:textBlockItemType</td> </tr> <tr> <td><strong> Balance Type:</strong></td> <td>na</td> </tr> <tr> <td><strong> Period Type:</strong></td> <td>duration</td> </tr> </table></div> </div></td></tr> </table> </div> </body> </html> </div><div id="xbrl_R30" style="display:none"><html> <head> <title></title></link> </head> <body> <span style="display: none;">v3.19.3</span><table class="report" border="0" cellspacing="2" id="idm140525554302360"> <tr> <th class="tl" colspan="1" rowspan="2"><div style="width: 200px;"><strong>Discontinued Operations<br></strong></div></th> <th class="th" colspan="1">12 Months Ended</th> </tr> <tr><th class="th"><div>Dec. 31, 2010</div></th></tr> <tr class="re"> <td class="pl " style="border-bottom: 0px;" valign="top"><a class="a" href="javascript:void(0);" onclick="top.Show.showAR( this, 'defref_us-gaap_DisposalGroupIncludingDiscontinuedOperationAdditionalDisclosuresAbstract', window );"><strong>Discontinued Operations [Abstract]</strong></a></td> <td class="text">&#160;<span></span> </td> </tr> <tr class="ro"> <td class="pl " style="border-bottom: 0px;" valign="top"><a class="a" href="javascript:void(0);" onclick="top.Show.showAR( this, 'defref_us-gaap_DisposalGroupsIncludingDiscontinuedOperationsDisclosureTextBlock', window );">Discontinued Operations</a></td> <td class="text"><!--DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" --> <!-- Begin Block Tagged Note 22 - us-gaap:DisposalGroupsIncludingDiscontinuedOperationsDisclosureTextBlock--> <div style="font-family: 'Times New Roman',Times,serif; margin-left: 0in; "> <div align="left" style="font-size: 10pt; margin-top: 10pt"><b>22.
