APS operates the plant and owns 63% of Four Corners Units 4 and 5 following the acquisition of SCE&#8217;s interest in Units 4 and 5 described below.&#160; APS has a total entitlement from Four Corners of 970 MW.  Additionally, 4CA, a wholly-owned subsidiary of Pinnacle West, owned 7% of Units 4 and 5 from July 2016 through July 2018 following its acquisition of El Paso's interest in these units described below.</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On December 30, 2013, APS purchased SCE&#8217;s 48% interest in each of Units 4 and 5 of Four Corners.

Also occurring concurrently with the closing, the Four Corners&#8217; co-owners executed a long-term agreement for the supply of coal to Four Corners from July 2016 through 2031 (the "2016 Coal Supply Agreement").  El Paso, a 7% owner of Units 4 and 5 of Four Corners, did not sign the 2016 Coal Supply Agreement.  Under the 2016 Coal Supply Agreement, APS agreed to assume the 7% shortfall obligation.  (See Note 10 for a discussion of certain matters related to the 2016 Coal Supply Agreement.)  On February 17, 2015, APS and El Paso entered into an asset purchase agreement providing for the purchase by APS, or an affiliate of APS, of El Paso&#8217;s 7% interest in each of Units 4 and 5 of Four Corners.  4CA purchased the El Paso interest on July 6, 2016.  The purchase price was immaterial in amount, and 4CA assumed El Paso's reclamation and decommissioning obligations associated with the 7% interest.   </span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">NTEC had the option to purchase the 7% interest within a certain timeframe pursuant to an option granted to NTEC.  On December 29, 2015, NTEC provided notice of its intent to exercise the option.  The purchase did not occur during the originally contemplated timeframe.  Concurrent with the settlement of the 2016 Coal Supply Agreement matter described in Note 10, NTEC and 4CA agreed to allow for the purchase by NTEC of the 7% interest, consistent with the option.  On June 29, 2018, 4CA and NTEC entered into an asset purchase agreement providing for the sale to NTEC of 4CA's 7% interest in Four Corners.  Completion of the sale was subject to the receipt of approval by FERC, which was received on July 2, 2018, and the sale transaction closed on July 3, 2018.  NTEC purchased the 7% interest at 4CA&#8217;s book value, approximately $70 million, and will pay 4CA the purchase price over a period of four years pursuant to a secured interest-bearing promissory note.  In connection with the sale, Pinnacle West guaranteed certain obligations that NTEC will have to the other owners of Four Corners, such as NTEC's 7% share of capital expenditures and operating and maintenance expenses.  Pinnacle West's guarantee is secured by a portion of APS's payments to be owed to NTEC under the 2016 Coal Supply Agreement.</span></div><div style="line-height:174%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">The 2016 Coal Supply Agreement contained alternate pricing terms for the 7% interest in the event NTEC did not purchase the interest.  Until the time that NTEC purchased the 7% interest, the alternate pricing provisions were applicable to 4CA as the holder of the 7% interest.  These terms included a formula under which NTEC must make certain payments to 4CA for reimbursement of operations and maintenance costs and a specified rate of return, offset by revenue generated by 4CA&#8217;s power sales.  Such payments are due to 4CA at the end of each calendar year.  A $10 million payment was due to 4CA at December 31, 2017, which NTEC satisfied by directing to 4CA a prepayment from APS of a portion of a future mine reclamation obligation.  The balance of the amount under this formula due December 31, 2018 for calendar year 2017 is approximately $20 million, which was paid to 4CA on December 14, 2018.  The balance of the amount under this formula at December 31, 2018 for calendar year 2018 (up to the date that NTEC purchased the 7% interest) is approximately $10 million, which is due to 4CA at December 31, 2019.</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;&#160;</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">APS, on behalf of the Four Corners participants, negotiated amendments to an existing facility lease with the Navajo Nation, which extends the Four Corners leasehold interest from 2016 to 2041.&#160; The Navajo Nation approved these amendments in March&#160;2011.&#160; The effectiveness of the amendments also required the approval of the DOI, as did a related federal rights-of-way grant.&#160; A federal environmental review was undertaken as part of the DOI review process, and culminated in the issuance by DOI of a record of decision on July 17, 2015 justifying the agency action extending the life of the plant and the adjacent mine.  &#160; </span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On April 20, 2016, several environmental groups filed a lawsuit against OSM and other federal agencies in the District of Arizona in connection with their issuance of the approvals that extended the life of Four Corners and the adjacent mine.&#160; The lawsuit alleges that these federal agencies violated both the Endangered Species Act ("ESA") and the National Environmental Policy Act ("NEPA") in providing the </span></div><div><br/></div><div><div style="line-height:120%;text-align:center;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">5</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;font-size:8pt;"><a style="font-family:inherit;font-size:8pt;" href="#s9C4FF461B8B957B19F176BBFF325F895"><span style="font-family:inherit;font-size:8pt;">Table of Contents </span></a></div></div><div><br/></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">federal approvals necessary to extend operations at Four Corners and the adjacent Navajo Mine past July 6, 2016.&#160; APS filed a motion to intervene in the proceedings, which was granted on August 3, 2016.  </span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On September 15, 2016, NTEC, the company that owns the adjacent mine, filed a motion to intervene for the purpose of dismissing the lawsuit based on NTEC's tribal sovereign immunity.

On April 14, 2015, the ACC approved APS's plan to retire Unit 2, without expressing any view on the future recoverability of APS's remaining investment in the Unit, which was later addressed in the March 27, 2017 settlement agreement regarding APS's general retail case (the "2017 Settlement Agreement").  (See Note 3 for details related to the resulting regulatory asset and allowed recovery set forth in the 2017 Settlement Agreement.)  APS believes that the environmental benefits of this proposal are greater in the long-term than the benefits that would have resulted from adding the emissions control equipment.  APS closed Unit 2 on October 1, 2015.  Following the closure of Unit 2, APS has a total entitlement from Cholla of 387 MW.&#160; In early 2017, EPA approved a final rule incorporating APS's compromise proposal, which took effect for Cholla on April 26, 2017. </span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">APS purchases all of Cholla&#8217;s coal requirements from a coal supplier that mines all of the coal under long-term leases of coal reserves with the federal and state governments and private landholders.&#160; The Cholla coal contract runs through 2024.

On August 26, 2014, the NRC approved a final rule on the environmental effects of continued storage of spent nuclear fuel.  Renamed as the Continued Storage Rule, the NRC&#8217;s decision adopted the findings of the GEIS regarding the environmental impacts of storing spent fuel at any reactor site after the reactor&#8217;s licensed period of operations.  As a result, those generic impacts do not need to be re-analyzed in the environmental reviews for individual licenses.  Although Palo Verde had not been involved in any licensing actions affected by the D.C. Circuit&#8217;s June 8, 2012, decision, the NRC lifted its suspension on final licensing actions on all nuclear power plant licenses and renewals that went into effect when the D.C.

Additionally, APS owns 12 MW of solar photovoltaic systems installed across Arizona through the ACC-approved Schools and Government Program.  </span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;padding-bottom:13px;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">In December 2014, the ACC voted that it had no objection to APS implementing an APS-owned rooftop solar research and development program aimed at learning how to efficiently enable the integration of rooftop solar and battery storage with the grid.&#160; The first stage of the program, called the "Solar Partner Program," placed 8 MW of residential rooftop solar on strategically selected distribution feeders in an effort to maximize potential system benefits, as well as made systems available to limited-income customers who could not easily install solar through transactions with third parties.&#160;The second stage of the program, which included an additional 2 MW of rooftop solar and energy storage, placed two energy storage systems sized at 2 MW on two different high solar penetration feeders to test various grid-related operation improvements and system </span></div><div><br/></div><div><div style="line-height:120%;text-align:center;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">11</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;font-size:8pt;"><a style="font-family:inherit;font-size:8pt;" href="#s9C4FF461B8B957B19F176BBFF325F895"><span style="font-family:inherit;font-size:8pt;">Table of Contents </span></a></div></div><div><br/></div><div style="line-height:120%;padding-bottom:13px;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">interoperability, and was in operation by the end of 2016. &#160;The costs for this program have been included in APS's rate base as part of the 2017 Rate Case Decision.  </span></div><div style="line-height:120%;padding-bottom:13px;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">In the 2017 Rate Case Decision, the ACC also approved the "APS Solar Communities" program.  APS Solar Communities is a three-year program authorizing APS to spend $10 million - $15 million in capital costs each year to install utility-owned distributed generation systems on low to moderate income residential homes, buildings of non-profit entities, Title I schools and rural government facilities.  The 2017 Rate Case Decision provided that all  operations and maintenance expenses, property taxes, marketing and advertising expenses, and the capital carrying costs for this program will be recovered through the RES.</span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11pt;font-weight:bold;"></span><span style="font-family:inherit;font-size:11.5pt;font-weight:bold;">Energy Storage</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"></span><span style="font-family:inherit;font-size:11.5pt;">APS deploys a number of advanced technologies on its system, including energy storage.  Storage can provide capacity, improve power quality, be utilized for system regulation, integrate renewable generation, and can be used to defer certain traditional infrastructure investments.  Battery storage can also aid in integrating higher levels of renewables by storing excess energy when system demand is low and renewable production is high and then releasing the stored energy during peak demand hours later in the day and after sunset.  APS is utilizing grid-scale battery storage projects to evaluate the potential benefits for customers and further our understanding of how storage works with other advanced technologies and the grid.  We are preparing for additional battery storage in the future.  </span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">In early 2018, APS entered into a 15-year power purchase agreement for a 65 MW solar facility that charges a 50 MW solar-fueled battery.  Service under this agreement is scheduled to begin in 2021.  APS issued a request for proposal for approximately 106 MW of battery storage to be located at up to five of its AZ Sun sites.  Based upon our evaluation of the RFP responses, APS has decided to expand the initial phase of battery deployment to 141 MW by adding a sixth AZ Sun site.  In February 2019, we contracted for the 141 MW and anticipate such facilities could be in service by mid-2020.  Additionally, in February 2019, APS signed two 20-year power purchase agreements for energy storage totaling 150 MW.  Service under these agreements are scheduled to begin in 2021. &#160;We plan to install at least an additional 660 MW of APS-owned solar plus battery storage and stand-alone battery storage systems by the summer of 2025, with the first 260 MW being procured in 2019 (60 MW on additional AZ Sun sites and 100 MW of solar plus 100 MW of battery storage).&#160;</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-weight:bold;text-decoration:underline;">Purchased Power Contracts</span><span style="font-family:inherit;font-size:11.5pt;font-weight:bold;">  </span></div><div style="line-height:120%;padding-top:8px;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">In addition to its own available generating capacity, APS purchases electricity under various arrangements, including long-term contracts and purchases through short-term markets to supplement its owned or leased generation and hedge its energy requirements.&#160; A portion of APS&#8217;s purchased power expense is netted against wholesale sales on the Consolidated Statements of Income.&#160; (See Note 16.)&#160; APS continually assesses its need for additional capacity resources to assure system reliability.  In addition, APS has also entered into several power purchase agreements for energy storage.

style="font-family:inherit;font-size:11.5pt;">Electric power demand is generally seasonal.&#160; In Arizona, demand for power peaks during the hot summer months.&#160; APS&#8217;s 2018 peak one-hour demand on its electric system was recorded on July 24, 2018 at 7,320 MW, compared to the 2017 peak of 7,363 MW recorded on June 20, 2017.&#160; APS&#8217;s reserve margin at the time of the 2018 peak demand, calculated using system load serving capacity, was 18%.&#160; For 2019, due to expiring purchase contracts, APS is procuring market resources to maintain its minimum 15% planning reserve

APS's participation in the EIM began on October 1, 2016.&#160; The EIM allows for rebalancing supply and demand in 15-minute blocks, with dispatching every five minutes before the energy is needed, instead of the traditional one hour blocks. &#160;APS continues to expect that its participation in EIM will lower its fuel costs, improve visibility and situational awareness for system operations in the Western Interconnection power grid, and improve integration of APS&#8217;s renewable resources.</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-weight:bold;">Renewable Energy Standard </span></div><div style="line-height:120%;padding-top:8px;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">In 2006, the ACC adopted the RES.&#160; 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.&#160; The renewable energy requirement is 9% of retail electric sales in 2019 and increases annually until it reaches 15% in 2025.&#160; In APS&#8217;s 2009 general retail rate case settlement agreement (the &#8220;2009 Settlement Agreement&#8221;), APS committed to use its best efforts to have 1,700 GWh of new renewable resources in service by year-end 2015 in addition to its RES renewable resource commitments.

Neither APS nor Pinnacle West produced the information requested and instead objected to the subpoena.  On March 10, 2017, Commissioner Burns filed suit against APS and Pinnacle West in the Superior Court of Arizona for Maricopa County in an effort to enforce his subpoenas.  On March 30, 2017, APS filed a motion to dismiss Commissioner Burns' suit against APS and Pinnacle West.

In the event climate change legislation ultimately passes, the actual economic and operational impact of such legislation on APS depends on a variety of factors, none of which can be fully known until a law is written and enacted and the specifics of the resulting program are established.  These factors include the terms of the legislation with regard to allowed GHG emissions; the cost to reduce emissions; in the event a cap-and-trade program is established, whether any permitted emissions allowances will be allocated to source operators free of cost or auctioned (and, if so, the cost of those allowances in the marketplace) and whether offsets and other measures to moderate the costs of compliance will be available; and, in the event of a carbon tax, the amount of the tax per pound of carbon dioxide (&#8220;CO</span><span style="font-family:inherit;font-size:11.5pt;"><sub style="vertical-align:bottom;line-height:120%;font-size:pt">2</sub></span><span style="font-family:inherit;font-size:11.5pt;">&#8221;) equivalent emitted.</span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">In addition to federal legislative initiatives, state-specific initiatives may also impact our business.  While Arizona has no pending legislation and no proposed agency rule regulating GHGs in Arizona at this time, the California legislature enacted AB 32 and SB 1368 in 2006 to address GHG emissions.  In October 2011, the California Air Resources Board approved final regulations that established a state-wide cap on GHG emissions beginning on January 1, 2013 and established a GHG allowance trading program under that cap.  The first phase of the program, which applies to, among other entities, importers of electricity, commenced on January&#160;1, 2013.  Under the program, entities selling electricity into California, including APS, must hold carbon allowances to cover GHG emissions associated with electricity sales into California from outside the state.  APS is authorized to recover the cost of these carbon allowances through the PSA.  </span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-style:italic;font-weight:bold;">Regulatory Initiatives.</span><span style="font-family:inherit;font-size:11.5pt;">  In 2009, EPA determined that GHG emissions endanger public health and welfare.  As a result of this &#8220;endangerment finding,&#8221; EPA determined that the Clean Air Act required new regulatory requirements for new and modified major GHG emitting sources, including power plants.  APS will generally be required to consider the impact of GHG emissions as part of its traditional New Source Review ("NSR") analysis for new major sources and major modifications to existing plants.</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On June 2, 2014, EPA issued two proposed rules to regulate GHG emissions from modified and reconstructed electric generating units ("EGUs") pursuant to Section 111(b) of the Clean Air Act and existing fossil fuel-fired power plants pursuant to Clean Air Act Section 111(d).  On August 3, 2015, EPA finalized carbon pollution standards for EGUs, the "Clean Power Plan".  On October 10, 2017, EPA issued a proposal to repeal the Clean Power Plan and proposed replacement regulations on August 21, 2018.  In addition, judicial challenges to the Clean Power Plan are pending before the D.C.

The rules require states (or, for sources located on tribal land, EPA) to determine what pollution control technologies constitute the BART for certain older major stationary sources, including fossil-fired power plants.  EPA subsequently issued the Clean Air Visibility Rule, which provides guidelines on how to perform a BART analysis.</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-style:italic;">Cholla.  </span><span style="font-family:inherit;font-size:11.5pt;">APS believed that EPA&#8217;s original 2012 final rule&#160;establishing controls constituting BART for Cholla, which would require installation of selective catalytic reduction ("SCR") controls, was unsupported and that EPA had no basis for disapproving Arizona&#8217;s State Implementation Plan ("SIP") and promulgating a Federal Implementation Plan ("FIP") that was inconsistent with the state&#8217;s considered BART determinations under the regional haze program.&#160; In September 2014, APS met with EPA to propose a compromise BART strategy, whereby APS would permanently close Cholla Unit 2 and cease burning coal at Units 1 and 3 by the mid-2020s.  (See Note 3 for details related to the resulting regulatory asset.)  APS made the proposal with the understanding that additional emission control equipment is unlikely to be required in the future because retiring and/or converting the units as contemplated in the proposal is more cost effective than, and will result in increased visibility improvement over, the BART requirements for oxides of nitrogen ("NOx") imposed through EPA's BART FIP.  In early 2017, EPA approved a final rule incorporating APS's compromise proposal, which took effect for Cholla on April 26, 2017.      </span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;&#160;&#160;&#160;</span></div><div><br/></div><div><div style="line-height:120%;text-align:center;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">20</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;font-size:8pt;"><a style="font-family:inherit;font-size:8pt;" href="#s9C4FF461B8B957B19F176BBFF325F895"><span style="font-family:inherit;font-size:8pt;">Table of Contents </span></a></div></div><div><br/></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-style:italic;">Four Corners</span><span style="font-family:inherit;font-size:11.5pt;">.  Based on EPA&#8217;s final standards, APS's 63% share of the cost of required BART controls for Four Corners Units 4 and 5 is approximately $400 million, the majority of which has already been incurred.&#160; (See Note 3 for information regarding the related rate recovery.)  In addition, APS and El Paso entered into an asset purchase agreement providing for the purchase by APS, or an affiliate of APS, of El Paso's 7% interest in Four Corners Units 4 and 5.  4CA purchased the El Paso interest on July 6, 2016.  NTEC purchased the interest from 4CA on July 3, 2018.  (See "Four Corners Coal Supply Agreement - 4CA Matter" in Note 10 for a discussion of the NTEC purchase.)  The cost of the pollution controls related to the 7% interest is approximately $45 million, which was assumed by NTEC through its purchase of the 7% interest.</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;</span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-style:italic;">Navajo Plant</span><span style="font-family:inherit;font-size:11.5pt;">.

The rule regulates CCR as a non-hazardous waste under Subtitle D of the Resource Conservation and Recovery Act ("RCRA") and establishes national minimum criteria for existing and new CCR landfills and surface impoundments and all lateral expansions consisting of location restrictions, design and operating criteria, groundwater monitoring and corrective action, closure requirements and post closure care, and recordkeeping, notification, and internet posting requirements.  The rule generally requires any existing unlined CCR surface impoundment that is contaminating groundwater above a regulated constituent&#8217;s groundwater protection standard to stop receiving CCR and either retrofit or close, and further requires the closure of any CCR landfill or surface impoundment that cannot meet the applicable performance criteria for location restrictions or structural integrity.  Such closure requirements are deemed "forced closure" or "closure for cause" of unlined surface impoundments, and are the subject of recent regulatory and judicial activities described below.</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On December 16, 2016, President Obama signed the Water Infrastructure Improvements for the Nation ("WIIN") Act into law, which contains a number of provisions requiring EPA to modify the self-implementing provisions of the Agency's current CCR rules under Subtitle D.  Such modifications include new EPA authority to directly enforce the CCR rules through the use of administrative orders and providing states, like Arizona, where the Cholla facility is located, the option of developing CCR disposal unit permitting programs, subject to EPA approval.  For facilities in states that do not develop state-specific permitting programs, EPA is required to develop a federal permit program, pending the availability of congressional appropriations.  By contrast, for facilities located within the boundaries of Native American tribal reservations, such as the Navajo Nation, where the Navajo Plant and Four Corners facilities are located, EPA is required to develop a federal permit program regardless of appropriated funds.</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">ADEQ has initiated a process to evaluate how to develop a state CCR permitting program that would cover EGUs, including Cholla.  While APS has been working with ADEQ on the development of this program, we are unable to predict when Arizona will be able to finalize and secure EPA approval for a state-specific CCR permitting program.  With respect to the Navajo Nation, APS has sought clarification as to when and how EPA would be initiating permit proceedings for facilities on the reservation, including Four Corners.  We are unable to predict at this time when EPA will be issuing CCR management permits for the facilities on the Navajo Nation.  At this time, it remains unclear how the CCR provisions of the WIIN Act will affect APS and its management of CCR.</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">Based upon utility industry petitions for EPA to reconsider the RCRA Subtitle D regulations for CCR, which were premised in part on the CCR provisions of the 2016 WIIN Act, on September 13, 2017, EPA </span></div><div><br/></div><div><div style="line-height:120%;text-align:center;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">21</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;font-size:8pt;"><a style="font-family:inherit;font-size:8pt;" href="#s9C4FF461B8B957B19F176BBFF325F895"><span style="font-family:inherit;font-size:8pt;">Table of Contents </span></a></div></div><div><br/></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">agreed to evaluate whether to revise these federal CCR regulations.  On July 17, 2018, EPA finalized a revision to its RCRA Subtitle D regulations for CCR, the "Phase I, Part I" revision to its CCR regulations, deferring for future action a number of other proposed changes contemplated in a March 1, 2018 proposal.  For the final rule issued on July 17, 2018, EPA established nationwide health-based standards for certain constituents of CCR subject to groundwater corrective action, and delayed the closure deadlines for certain unlined CCR surface impoundments by 18 months (for example, those disposal units required to undergo forced closure).  These changes to the federal regulations governing CCR disposal are unlikely to have a material impact on APS.  As for those aspects of the March 2018 rulemaking proposal for which EPA has yet to take final action, it remains unclear which specific provisions of the federal CCR rules will ultimately be modified, how they will be modified, or when such modification will occur.</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">Pursuant to a June 24, 2016 order by the D.C. Circuit Court of Appeals in the litigation by industry- and environmental-groups challenging EPA&#8217;s CCR regulations, EPA is required to complete a rulemaking proceeding in the near future concerning whether or not boron must be included on the list of groundwater constituents that might trigger corrective action under EPA&#8217;s CCR rules.&#160; Simultaneously with the issuance of EPA's proposed modifications to the federal CCR rules in response to industry petitions, on March 1, 2018, EPA issued a proposed rule seeking comment as to whether or not boron should be included on this list.  EPA is not required to take final action approving the inclusion of boron.&#160; Should EPA take final action adding boron to the list of groundwater constituents that might trigger corrective action, any resulting corrective action measures may increase APS's costs of compliance with the CCR rule at our coal-fired generating facilities.&#160; At this time APS cannot predict the eventual results of this rulemaking proceeding concerning boron.</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On August 21, 2018, the D.C. Circuit Court issued its decision on the merits in this litigation.  The Court upheld the legality of EPA&#8217;s CCR regulations, though it vacated and remanded back to EPA a number of specific provisions, which are to be corrected in accordance with the Court&#8217;s order.  Among the issues affecting APS&#8217;s management of CCR, the D.C. Circuit&#8217;s decision vacated and remanded those provisions of the EPA CCR regulations that allow for the operation of unlined CCR surface impoundments, even where those unlined impoundments have not otherwise violated a regulatory location restriction or groundwater protection standard (i.e., otherwise triggering forced closure).  At this time, it remains unclear how this D.C. Circuit Court decision will affect APS&#8217;s operations or financial results, as EPA has yet to take regulatory action on remand to revise its 2015 CCR regulations consistent with the Court&#8217;s order.</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">Based on this decision, on December 17, 2018, certain environmental groups filed an emergency motion with the D.C. Circuit to either stay or summarily vacate EPA's July 17, 2018 final rule extending the closure-initiation deadline for certain unlined CCR surface impoundments until October 2020.  In response, EPA filed a motion to remand but not vacate that deadline extension regulation.  We cannot predict the outcome of the D.C.

APS estimates that its share of incremental costs to comply with the CCR rule for Four Corners is approximately $22 million and its share of incremental costs to comply with the CCR rule for Cholla is approximately $20 million.  The Navajo Plant currently disposes of CCR in a dry landfill storage area.  APS estimates that its share of incremental costs to comply with the CCR rule for the Navajo Plant is approximately $1 million.  Additionally, the CCR rule requires ongoing, phased groundwater monitoring.  By October 17, 2017, electric utility companies that own or operate CCR disposal units, such as APS, must have collected sufficient groundwater sampling data to initiate a detection monitoring program.&#160; To the extent that certain threshold constituents are identified through this initial detection monitoring at levels above the CCR rule&#8217;s standards, the rule required the initiation of an assessment monitoring program by April 15, 2018.</span></div><div><br/></div><div><div style="line-height:120%;text-align:center;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">22</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;font-size:8pt;"><a style="font-family:inherit;font-size:8pt;" href="#s9C4FF461B8B957B19F176BBFF325F895"><span style="font-family:inherit;font-size:8pt;">Table of Contents </span></a></div></div><div><br/></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">APS recently completed the statistical analyses for its CCR disposal units that triggered assessment monitoring.  APS determined that several of its CCR disposal units at Cholla and Four Corners will need to undergo corrective action.  In addition, all such units must cease operating and initiate closure by October of 2020.  APS currently estimates that the additional incremental costs to complete this corrective action and closure work, along with the costs to develop replacement CCR disposal capacity, could be approximately $5 million for both Cholla and Four Corners.  APS initiated an assessment of corrective measures on January 14, 2019, and anticipates completing this assessment during the summer of 2019.  During this assessment, APS will gather additional groundwater data, solicit input from the public, host public hearings, and select remedies.  As such, this $5 million cost estimate may change based upon APS&#8217;s performance of the CCR rule&#8217;s corrective action assessment process.  Given uncertainties that may exist until we have fully completed the corrective action assessment process, we cannot predict any ultimate impacts to the Company; however, at this time we do not believe any potential change to the cost estimate would have a material impact on our financial position, results of operations or cash flows.</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-style:italic;font-weight:bold;">Effluent Limitation Guidelines.</span><span style="font-family:inherit;font-size:11.5pt;">  On September 30, 2015, EPA finalized revised effluent limitation guidelines establishing technology-based wastewater discharge limitations for fossil-fired EGUs.&#160; EPA&#8217;s final regulation targets metals and other pollutants in wastewater streams originating from fly ash and bottom ash handling activities, scrubber activities, and coal ash disposal leachate.&#160; Based upon an earlier set of preferred alternatives, the final effluent limitations generally require chemical precipitation and biological treatment for flue gas desulfurization scrubber wastewater, &#8220;zero discharge&#8221; from fly ash and bottom ash handling, and impoundment for coal ash disposal leachate.&#160; </span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On August 11, 2017, EPA announced that it would be initiating rulemaking proceedings to potentially revise the September 2015 effluent limitation guidelines. On September 18, 2017, EPA finalized a regulation postponing the earliest date on which compliance with the effluent limitation guidelines for these waste-streams would be required from November 1, 2018 until November 1, 2020.  Until EPA issues a proposal describing how it intends to change the effluent limitation guidelines for bottom ash transport water and flue gas desulfurization wastewater, it is unclear how EPA&#8217;s reconsideration process will affect how the Four Corners plant manages these waste-streams.   We expect that compliance with these limitations will be required in connection with National Pollution Discharge Elimination System ("NPDES") discharge permit renewals.&#160;  APS anticipates that, in connection with EPA's current reconsideration of the NPDES permit for Four Corners (see "Four Corners National Pollutant Discharge Elimination System Permit" below), EPA will propose a compliance deadline for the effluent limitation guidelines governing bottom ash transport water during March of 2019.  Until EPA proposes a new NPDES permit reissuance for Four Corners, it is unclear what date EPA will assign as a compliance deadline for Four Corners.  Cholla and the Navajo Plant do not require NPDES permitting. </span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-style:italic;font-weight:bold;">Ozone National Ambient Air Quality Standards.  </span><span style="font-family:inherit;font-size:11.5pt;">On October 1, 2015, EPA finalized revisions to the primary ground-level ozone national ambient air quality standards (&#8220;NAAQS&#8221;) at a level of 70 parts per billion (&#8220;ppb&#8221;).&#160; With ozone standards becoming more stringent, our fossil generation units will come under increasing pressure to reduce emissions of NOx and volatile organic compounds, and to generate emission offsets for new projects or facility expansions located in ozone nonattainment areas.&#160; EPA was expected to designate attainment and nonattainment areas relative to the new 70 ppb standard by October 1, 2017.&#160;  While EPA took action designating attainment and unclassifiable areas on November 6, 2017, the Agency's final action designating non-attainment areas was not issued until April 30, 2018.  At that time, EPA designated the geographic areas containing Yuma and Phoenix, Arizona as in non-attainment with the 2015 70 ppb ozone NAAQS. The vast majority of APS's natural gas-fired EGUs are located in these jurisdictions.

We estimate that our costs related to this investigation and study will be approximately $2 million.&#160; 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 expenditures related to this matter cannot be reasonably estimated.</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On August&#160;6, 2013, the Roosevelt Irrigation District ("RID") filed a lawsuit in Arizona District Court against APS and 24 other defendants, alleging that RID&#8217;s groundwater wells were contaminated by the release of hazardous substances from facilities owned or operated by the defendants.&#160; The lawsuit also alleges that, under Superfund laws, the defendants are jointly and severally liable to RID.&#160; The allegations against APS arise out of APS&#8217;s current and former ownership of facilities in and around OU3.&#160; As part of a state governmental investigation into groundwater contamination in this area, on January 25, 2015, ADEQ sent a letter to APS seeking information concerning the degree to which, if any, APS&#8217;s current and former ownership of these facilities may have contributed to groundwater contamination in this area.&#160; APS responded to ADEQ on May 4, 2015.  On December 16, 2016, two RID environmental and engineering contractors filed an ancillary lawsuit for recovery of costs against APS and the other defendants in the RID litigation.  That same day, another RID service provider filed an additional ancillary CERCLA lawsuit against certain of the defendants in the main RID litigation, but excluded APS and certain other parties as named defendants.  Because the ancillary lawsuits concern past costs allegedly incurred by these RID vendors, which were ruled unrecoverable directly by RID in November of 2016, the additional lawsuits do not increase APS's exposure or risk related to these matters.</span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On April 5, 2018, RID and the defendants in that particular litigation executed a settlement agreement, fully resolving RID's CERCLA claims concerning both past and future cost recovery.  APS's share of this settlement was immaterial.  In addition, the two environmental and engineering vendors voluntarily dismissed their lawsuit against APS and the other named defendants without prejudice.  An order to this effect was entered on April 17, 2018.  With this disposition of the case, the vendors may file their lawsuit again in the future.  In addition, APS and certain other parties not named in the remaining RID service provider lawsuit may be brought into the litigation via third-party complaints filed by the current direct defendants.

Withdrawal of the permit moots the EAB appeal, and EPA filed a motion to dismiss on that basis.  EPA indicated that it anticipates proposing a replacement NPDES permit by March 2019 and, depending on the extent of public comments concerning that proposal, taking final action on a new NPDES permit by June 2019.

At the present time, APS has adequate water to meet its operating needs.  The Four Corners region, in which Four Corners is located, has historically experienced drought conditions that may affect the water supply for the plants if adequate moisture is not received in the watershed that supplies the area.  However, during the past 12 months the region has received snowfall and precipitation sufficient to recover the Navajo Reservoir to an optimum operating level, reducing the probability of shortage in future years.  Although the watershed and reservoirs are in a good condition at this time, APS is continuing to work with area stakeholders to implement agreements to minimize the effect, if any, on future drought conditions that could have an impact on operations of its plants.  </span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">Conflicting claims to limited amounts of water in the southwestern United States have resulted in numerous court actions, which, in addition to future supply conditions, have the potential to impact APS&#8217;s operations.</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-style:italic;font-weight:bold;">San Juan River Adjudication.  </span><span style="font-family:inherit;font-size:11.5pt;">Both groundwater and surface water in areas important to APS&#8217;s operations have been the subject of inquiries, claims, and legal proceedings, which will require a number of years to resolve.  APS is one of a number of parties in a proceeding, filed March&#160;13, 1975, before the Eleventh Judicial District Court in New Mexico to adjudicate rights to a stream system from which water for Four Corners is derived.  An agreement reached with the Navajo Nation in 1985, however, provides that if Four Corners loses a portion of its rights in the adjudication, the Navajo Nation will provide, for an agreed upon cost, sufficient water from its allocation to offset the loss.  In addition, APS is a party to a water contract that allows the company to secure water for Four Corners in the event of a water shortage and is a party to a shortage sharing agreement, which provides for the apportionment of water supplies to Four Corners in the event of a water shortage in the San Juan River Basin.</span></div><div style="line-height:174%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-style:italic;font-weight:bold;">Gila River Adjudication.  </span><span style="font-family:inherit;font-size:11.5pt;">A summons served on APS in early 1986 required all water claimants in the Lower Gila River Watershed in Arizona to assert any claims to water on or before January 20, 1987, in an action pending in Arizona Superior Court.  Palo Verde is located within the geographic area subject to the summons.  APS&#8217;s rights and the rights of the other Palo Verde participants to the use of groundwater and effluent at Palo Verde are potentially at issue in this adjudication.  As operating agent of Palo Verde, APS filed claims that dispute the court&#8217;s jurisdiction over the Palo Verde participants&#8217; groundwater rights and their contractual rights to effluent relating to Palo Verde.  Alternatively, APS seeks confirmation of such rights.  Several of APS&#8217;s other power plants are also located within the geographic area subject to the summons, including a number of gas-fired power plants located within Maricopa and Pinal Counties.

In addition, in September 2000, the Arizona Supreme Court issued a decision affirming the lower court&#8217;s criteria for resolving groundwater claims.  Litigation on both of these issues has continued in the trial court.  In December 2005, APS and other parties filed a petition with the Arizona Supreme Court requesting interlocutory review of a September 2005 trial court order regarding procedures for determining whether groundwater pumping is affecting surface water rights.  The Arizona Supreme Court denied the petition in May 2007, and the trial court is now proceeding with implementation of its 2005 order.

A hearing to determine this jurisdictional test question was held in March of 2018 in front of a special master, and a draft decision based on the evidence heard during that hearing was issued on May 17, 2018.  The decision of the special master, which was finalized on November 14, 2018, but which is subject to further review by the trial court judge, accepts the proposed hydro-geologic testing protocols supported by APS and other industrial users of groundwater.  Upon a final decision by the trial court judge in this matter, further proceedings thereafter will be dedicated to determining the specific hydro-geologic testing protocols for subflow depletion determinations.  The determinations made in this final stage of the proceedings will ultimately govern the adjudication of rights for parties, such as APS, that rely on groundwater extraction to support their industrial operations.

These agencies regulate many aspects of APS&#8217;s utility operations, including safety and performance, emissions, siting and construction of facilities, customer service and the rates that APS can charge retail and wholesale customers.&#160; Failure to comply can subject APS to, among other things, fines and penalties.&#160; For example, under the Energy Policy Act of 2005, FERC can impose penalties (approximately $1.2 million dollars per day per violation) for failure to comply with mandatory electric reliability standards.&#160; APS is also required to have numerous permits, approvals and certificates from these agencies.&#160; APS believes the necessary permits, approvals and certificates have been obtained for its existing operations and that APS&#8217;s business is conducted in accordance with applicable laws in all material respects.&#160;

The rule regulates CCR as a non-hazardous waste.  APS currently disposes of CCR in ash ponds and dry storage areas at Cholla and Four Corners and in a dry landfill storage area at the Navajo Plant.  To the extent the rule requires the closure or modification of these CCR units or the construction of new CCR units beyond what we currently anticipate, APS would incur significant additional costs for CCR disposal.  In addition, the rule may also require corrective action to address releases from CCR disposal units or the presence of CCR constituents within groundwater near CCR disposal units above certain regulatory thresholds. </span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-style:italic;">Ozone National Ambient Air Quality Standards. </span><span style="font-family:inherit;font-size:11pt;font-style:italic;font-weight:bold;"> </span><span style="font-family:inherit;font-size:11.5pt;">In 2015, EPA finalized revisions to the national ambient air quality standards for nitrogen oxides, which set new, more stringent standards intended to protect human health and human welfare.

The implementation of this rule within the jurisdictions where APS operates could result in a shift in in-state generation from coal to natural gas and renewable generation.  Such a substantial change in APS&#8217;s generation portfolio could require additional capital investments and increased operating costs, and thus have a significant financial impact on the Company.  EPA took action in October 2017 to repeal these regulations and in August 2018 EPA proposed the Affordable Clean Energy Rule to replace the Clean Power Plan with a new set of regulations.   </span></div><div><br/></div><div><div style="line-height:120%;text-align:center;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">31</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;font-size:8pt;"><a style="font-family:inherit;font-size:8pt;" href="#s9C4FF461B8B957B19F176BBFF325F895"><span style="font-family:inherit;font-size:8pt;">Table of Contents </span></a></div></div><div><br/></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">Depending on the final outcome of a pending judicial review of the Clean Power Plan, along with related regulatory activity to repeal or replace these regulations, the utility industry may face alternative efforts from private parties seeking to establish alternative GHG emission limitations from power plants.  Alternative GHG emission limitations may arise from litigation under either federal or state common laws or citizen suit provisions of federal environmental statutes that attempt to force federal agency rulemaking or imposing direct facility emission limitations.  Such lawsuits may also seek damages from harm alleged to have resulted from power plant GHG emissions.  </span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-style:italic;">Physical and Operational Risks.</span><span style="font-family:inherit;font-size:11pt;font-style:italic;font-weight:bold;">  </span><span style="font-family:inherit;font-size:11.5pt;">Weather extremes such as drought and high temperature variations are common occurrences in the Southwest&#8217;s desert area, and these are risks that APS considers in the normal course of business in the engineering and construction of its electric system.

Changes in the nature of our industry and the economic viability of certain plants, including impacts resulting from types and availability of other resources, fuel costs, legislation and regulation, together with timing considerations related to expiration of leases or other agreements for such facilities, could result in unaligned positions among co-owners.  Such differences in the co-owners&#8217; willingness or ability to continue their participation could ultimately lead to disagreements among the parties as to how and whether to continue operation of such plants, which could lead to eventual shut down of units or facilities and uncertainty related to the resulting cost recovery of such assets.

The ruling also voided the operating authority of all the competitive providers previously authorized by the ACC.  On May&#160;9, 2013, the ACC voted to re-examine the facilitation of a deregulated retail electric market in Arizona.&#160; The ACC subsequently opened a docket for this matter and received comments from a number of interested parties on the considerations involved in establishing retail electric deregulation in the state.&#160; One of these considerations is whether various aspects of a deregulated market, including setting utility rates on a &#8220;market&#8221; basis, would be consistent with the requirements of the Arizona Constitution.&#160; On September&#160;11, 2013, after receiving legal advice from the ACC staff, the ACC voted 4-1 to close the current docket and await full Arizona Constitutional authority before any further examination of this matter.&#160; The motion approved by the ACC also included opening one or more new dockets in the future to explore options to offer more rate choices to customers and innovative changes within the existing cost-of-service regulatory model that could include elements of competition.&#160; </span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">One of these options would be a continuation or expansion of APS&#8217;s existing AG (Alternative Generation)-X program, which essentially allows up to 200 MW of cumulative load to be served via a buy-</span></div><div><br/></div><div><div style="line-height:120%;text-align:center;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">32</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;font-size:8pt;"><a style="font-family:inherit;font-size:8pt;" href="#s9C4FF461B8B957B19F176BBFF325F895"><span style="font-family:inherit;font-size:8pt;">Table of Contents </span></a></div></div><div><br/></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">through arrangement with competitive suppliers of generation.&#160; The AG-X program was approved by the ACC as part of the 2017 Settlement Agreement.</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">In November 2018, the ACC voted to again re-examine retail competition.  Interested parties were asked to submit written comments, which are still being submitted.  In addition, proposals to enable or support retail electric competition may be made from time to time through ballot initiatives, legislative action or other forums in Arizona.  The ACC held one workshop on retail competition in December 2018 and is planning at least one more workshop on the issue in 2019.

Weather conditions directly influence the demand for electricity and affect the price of energy commodities.&#160; Electric power demand is generally a seasonal business.&#160; In Arizona, demand for power peaks during the hot summer months, with market prices also peaking at that time.&#160; As a result, APS&#8217;s overall operating results fluctuate substantially on a seasonal basis.&#160; In addition, APS has historically sold less power, and consequently earned less income, when weather conditions are milder.&#160;

The ACC has enacted rules&#160;regarding energy efficiency that mandate a 22% cumulative annual energy savings requirement by 2020.&#160; This will likely increase participation by APS customers in energy efficiency and conservation programs and other demand-side management efforts, which in turn will impact the demand for electricity.&#160; The rules&#160;also include a requirement for the ACC to review and address financial disincentives, recovery of fixed costs and the recovery of net lost income/revenue that would result from lower sales due to increased energy efficiency requirements.&#160;

A portion of APS&#8217;s total renewable energy requirement must be met with an increasing percentage of distributed energy resources (generally, small scale renewable technologies located on customers&#8217; properties).&#160; The distributed energy requirement was 25% of the overall RES requirement of 3% in 2011 and increased to 30% of the applicable RES requirement for 2012 and subsequent years.&#160; Customer participation in distributed energy programs would result in lower demand, since customers would be meeting some of their own energy needs.&#160;

Each year APS prepares and files with the ACC a ten-year transmission plan.&#160; In APS&#8217;s 2019 plan, APS projects it will develop 15 miles of new transmission lines over the next ten years.  One significant project, the Palo Verde to Morgan project recently completed all phases and is a new 500kV path that spans from the Palo Verde hub around the western and northern edges of the Phoenix metropolitan area and terminates at a bulk substation in the northeast part of Phoenix.  The Palo Verde to Morgan project includes Palo Verde-Delaney-Sun Valley-Morgan-Pinnacle Peak.  The project consisted of four phases and the fourth phase, Morgan to Sun Valley 500kV, was energized in April of 2018.  In total, the project consisted of over 100 miles of new 500kV lines, with many of those miles constructed with the capability to string a 230kV line as a second circuit.</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">APS continues to work with regulators to identify transmission projects necessary to support renewable energy facilities.

The North Gila to Hassayampa line went into service in May 2015 and the Delaney to Palo Verde line went into service in May 2016.</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-style:italic;font-weight:bold;">Physical Security Standards. </span><span style="font-family:inherit;font-size:11.5pt;"> On July 14, 2015, FERC approved version 2 of the proposed Physical Security Reliability Standard CIP-014.&#160; APS completed its initial implementation in 2018.&#160; No additional significant financial or operational impacts on APS are anticipated.</span></div><div style="line-height:120%;text-align:left;font-size:11pt;"><span style="font-family:inherit;font-size:11pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11pt;"></span><span style="font-family:inherit;font-size:11pt;font-style:italic;font-weight:bold;">NERC Critical Infrastructu</span><span style="font-family:inherit;font-size:11.5pt;font-style:italic;font-weight:bold;">re Protection Reliability Standards</span><span style="font-family:inherit;font-size:11.5pt;">.&#160; Since 2014, APS has been implementing a comprehensive project to ensure compliance with NERC's Critical Infrastructure Protection Reliability Standards ("CIP").&#160; As a result of recent revisions to the CIP standards, the final compliance date is now January 1, 2020.&#160; APS is 95% complete in its compliance implementation activities with total expenditures of $60.4 million incurred by APS as of December 31, 2018.&#160; APS anticipates an additional expenditure of approximately $0.2 million with a final completion date in September 2019.</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-weight:bold;">Plant and Transmission Line Leases and Rights-of-Way on Indian Lands</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;</span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">The Navajo Plant and Four Corners are located on land held under leases from the Navajo Nation and also under rights-of-way from the federal government.&#160;&#160; The co-owners of the Navajo Plant and the Navajo </span></div><div><br/></div><div><div style="line-height:120%;text-align:center;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">45</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;font-size:8pt;"><a style="font-family:inherit;font-size:8pt;" href="#s9C4FF461B8B957B19F176BBFF325F895"><span style="font-family:inherit;font-size:8pt;">Table of Contents </span></a></div></div><div><br/></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">Nation agreed that the Navajo Plant will remain in operation until December 2019 under the existing plant lease.

In recent negotiations, certain of the affected Indian tribes have required payments substantially in excess of amounts that we have paid in the past for such rights-of-way.&#160; The ultimate cost of renewal of certain of the rights-of-way for our transmission lines is therefore uncertain.</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div><a id="s4E4D7A94C9595ED8B56A5A4F0974890D"></a></div><div style="line-height:120%;text-align:center;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-weight:bold;">ITEM 3.&#160;

EPA is considering a proposed replacement to the Clean Power Plan, which was published on August 21, 2018.  This new proposal, the "Affordable Clean Energy Rule," is more narrow than its predecessor regulation, and is based entirely upon heat-rate improvements at steam-electric power plants.  See "Business - Environmental Matters - Climate Change - Regulatory Initiatives" for additional information on the current status of EPA's carbon pollution standards for EGUs.  APS continually analyzes its long-range capital management plans to assess the potential effects of such proposals, understanding that any resulting regulation and legislation could impact the economic viability of certain plants, as well as the willingness or ability of power plant participants to continue participation in such plants. </span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div><br/></div><div><div style="line-height:120%;text-align:center;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">51</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;font-size:8pt;"><a style="font-family:inherit;font-size:8pt;" href="#s9C4FF461B8B957B19F176BBFF325F895"><span style="font-family:inherit;font-size:8pt;">Table of Contents </span></a></div></div><div><br/></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-weight:bold;">Cholla</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On September 11, 2014, APS announced that it would close its 260 MW Unit 2 at Cholla and cease burning coal at the other APS-owned units (Units 1 and 3) at the plant by the mid-2020s, if EPA approves a compromise proposal offered by APS to meet required environmental and emissions standards and rules.  On April 14, 2015, the ACC approved APS's plan to retire Unit 2, without expressing any view on the future recoverability of APS's remaining investment in the Unit, which was later addressed in the 2017 Settlement Agreement.  (See Note 3 for details related to the resulting cost recovery.)  APS believes that the environmental benefits of this proposal are greater in the long-term than the benefits that would have resulted from adding emissions control equipment.  APS closed Unit 2 on October 1, 2015.  In early 2017, EPA approved a final rule incorporating APS's compromise proposal, which took effect for Cholla on April 26, 2017.

The final purchase price for the interest was approximately $182 million.  In connection with APS&#8217;s prior general retail rate case with the ACC, the ACC reserved the right to review the prudence of the Four Corners transaction for cost recovery purposes upon the closing of the transaction.  On December 23, 2014, the ACC approved rate adjustments related to APS&#8217;s acquisition of SCE&#8217;s interest in Four Corners resulting in a revenue increase of $57.1 million on an annual basis.  This decision was appealed and, on September 26, 2017, the Arizona Court of Appeals affirmed the ACC's decision on the Four Corners rate adjustment.  </span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;padding-bottom:13px;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">Concurrently with the closing of the SCE transaction described above, BHP Billiton, the parent company of BNCC, the coal supplier and operator of the mine that served Four Corners, transferred its ownership of BNCC to NTEC, a company formed by the Navajo Nation to own the mine and develop other energy projects.  Also occurring concurrently with the closing, the Four Corners&#8217; co-owners executed the 2016 Coal Supply Agreement for the supply of coal to Four Corners from July 2016 through 2031.  El Paso, a 7% owner in Units 4 and 5 of Four Corners, did not sign the 2016 Coal Supply Agreement.  Under the 2016 Coal Supply Agreement, APS agreed to assume the 7% shortfall obligation.  (See Note 10 for a discussion of a settlement related to the 2016 Coal Supply Agreement and an advance purchase of coal inventory made under the agreement.)  On February 17, 2015, APS and El Paso entered into an asset purchase agreement providing for the purchase by APS, or an affiliate of APS, of El Paso&#8217;s 7% interest in each of Units 4 and 5 of Four Corners.  4CA purchased the El Paso interest on July 6, 2016.  The purchase price was immaterial in amount, and 4CA assumed El Paso's reclamation and decommissioning obligations associated with the 7% interest.</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">NTEC had the option to purchase the 7% interest within a certain timeframe pursuant to an option granted to NTEC.  On December 29, 2015, NTEC provided notice of its intent to exercise the option.  The purchase did not occur during the originally contemplated timeframe.  Concurrent with the settlement of the 2016 Coal Supply Agreement matter described in Note 10, NTEC and 4CA agreed to allow for the purchase by NTEC of the 7% interest, consistent with the option.  On June 29, 2018, 4CA and NTEC entered into an asset purchase agreement providing for the sale to NTEC of 4CA's 7% interest in Four Corners.  Completion of the sale was subject to the receipt of approval by FERC, which was received on July 2, 2018, and the sale transaction closed on July 3, 2018.  NTEC purchased the 7% interest at 4CA&#8217;s book value, approximately $70 million, and will pay 4CA the purchase price over a period of four years pursuant to a secured interest-bearing promissory note.  In connection with the sale, Pinnacle West guaranteed certain obligations that NTEC will have to the other owners of Four Corners, such as NTEC's 7% share of capital expenditures and operating and maintenance expenses.  Pinnacle West's guarantee is secured by a portion of APS's payments to be owed to NTEC under the 2016 Coal Supply Agreement.</span></div><div><br/></div><div><div style="line-height:120%;text-align:center;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">52</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;font-size:8pt;"><a style="font-family:inherit;font-size:8pt;" href="#s9C4FF461B8B957B19F176BBFF325F895"><span style="font-family:inherit;font-size:8pt;">Table of Contents </span></a></div></div><div><br/></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">  &#160;&#160;&#160;&#160;The 2016 Coal Supply Agreement contained alternate pricing terms for the 7% interest in the event NTEC did not purchase the interest.  Until the time that NTEC purchased the 7% interest, the alternate pricing provisions were applicable to 4CA, as the holder of the 7% interest.  These terms included a formula under which NTEC must make certain payments to 4CA for reimbursement of operations and maintenance costs and a specified rate of return, offset by revenue generated by 4CA&#8217;s power sales.  Such payments are due to 4CA at the end of each calendar year.  A $10 million payment was due to 4CA at December 31, 2017, which NTEC satisfied by directing to 4CA a prepayment from APS of a portion of a future mine reclamation obligation.  The balance of the amount due under this formula at December 31, 2018 for calendar year 2017 was approximately $20 million, which was paid to 4CA on December 14, 2018.  The balance of the amount under this formula for calendar year 2018 (up to the date that NTEC purchased the 7% interest) is approximately $10 million, which is due to 4CA at December 31, 2019.</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-style:italic;font-weight:bold;">Lease Extension.</span><span style="font-family:inherit;font-size:11.5pt;">&#160; APS, on behalf of the Four Corners participants, negotiated amendments to an existing facility lease with the Navajo Nation, which extends the Four Corners leasehold interest from 2016 to 2041.&#160; The Navajo Nation approved these amendments in March&#160;2011.&#160; The effectiveness of the amendments also required the approval of the DOI, as did a related federal rights-of-way grant.&#160; A federal environmental review was undertaken as part of the DOI review process, and culminated in the issuance by DOI of a record of decision on July 17, 2015 justifying the agency action extending the life of the plant and the adjacent mine.  &#160; </span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On April 20, 2016, several environmental groups filed a lawsuit against OSM and other federal agencies in the District of Arizona in connection with their issuance of the approvals that extended the life of Four Corners and the adjacent mine.&#160; The lawsuit alleges that these federal agencies violated both the ESA and NEPA in providing the federal approvals necessary to extend operations at the Four Corners Power Plant and the adjacent Navajo Mine past July 6, 2016.&#160; APS filed a motion to intervene in the proceedings, which was granted on August 3, 2016.  </span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On September 15, 2016, NTEC, the company that owns the adjacent mine, filed a motion to intervene for the purpose of dismissing the lawsuit based on NTEC's tribal sovereign immunity.  On September 11, 2017, the Arizona District Court issued an order granting NTEC's motion, dismissing the litigation with prejudice, and terminating the proceedings.  On November 9, 2017, the environmental group plaintiffs appealed the district court order dismissing their lawsuit.  Oral argument for this appeal has been scheduled for March 2019.  We cannot predict whether this appeal will be successful and, if it is successful, the outcome of further district court proceedings.</span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;&#160;&#160;&#160;</span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"></span><span style="font-family:inherit;font-size:11.5pt;font-style:italic;font-weight:bold;">Wastewater Permit.  </span><span style="font-family:inherit;font-size:11.5pt;">On July 16, 2018, several environmental groups filed a petition for review before the EPA EAB concerning the NPDES wastewater discharge permit for Four Corners, which was reissued on June 12, 2018.&#160; The environmental groups allege that the permit was reissued in contravention of several requirements under the Clean Water Act and did not contain required provisions concerning EPA&#8217;s 2015 revised effluent limitation guidelines for steam-electric EGUs, 2014 existing-source regulations governing cooling-water intake structures, and effluent limits for surface seepage and subsurface discharges from coal-ash disposal facilities.&#160; To address certain of these issues through a reconsidered permit, EPA took action on December 19, 2018 to withdraw the NPDES permit reissued in June 2018.  Withdrawal of the permit moots the EAB appeal, and EPA filed a motion to dismiss on that basis.  EPA indicated that it anticipates proposing a replacement NPDES permit by March 2019 and, depending on the extent of public comments concerning that proposal, taking final action on a new NPDES permit by June 2019.  At this time, we cannot predict the outcome of EPA's reconsideration of the NPDES permit and whether reconsideration will have a material impact on our financial position, results of operations or cash flows.  </span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div><br/></div><div><div style="line-height:120%;text-align:center;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">53</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;font-size:8pt;"><a style="font-family:inherit;font-size:8pt;" href="#s9C4FF461B8B957B19F176BBFF325F895"><span style="font-family:inherit;font-size:8pt;">Table of Contents </span></a></div></div><div><br/></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">For additional information, see "Business of Arizona Public Service Company - Energy Sources and Resource Planning - Generation Facilities - Coal-Fueled Generating Facilities - Four Corners."&#160; </span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11pt;"><span style="font-family:inherit;font-size:11pt;font-weight:bold;">&#160;&#160;&#160;&#160;</span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11pt;"><span style="font-family:inherit;font-size:11pt;font-weight:bold;">Navajo Plant</span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">The co-owners of the Navajo Plant and the Navajo Nation agreed that the Navajo Plant will remain in operation until December 2019 under the existing plant lease.

Storage can provide capacity, improve power quality, be utilized for system regulation, integrate renewable generation, and can be used to defer certain traditional infrastructure investments.  Battery storage can also aid in integrating higher levels of renewables by storing excess energy when system demand is low and renewable production is high and then releasing the stored energy during peak demand hours later in the day and after sunset.  APS is utilizing grid-scale battery storage projects to evaluate the potential benefits for customers and further our understanding of how storage works with other advanced technologies and the grid.  We are preparing for additional battery storage in the future.  </span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">In early 2018, APS entered into a 15-year power purchase agreement for a 65 MW solar facility that charges a 50 MW solar-fueled battery.  Service under this agreement is scheduled to begin in 2021.  APS issued a request for proposal for approximately 106 MW of battery storage to be located at up to five of its AZ Sun sites.  Based upon our evaluation of the RFP responses, APS has decided to expand the initial phase of battery deployment to 141 MW by adding a sixth AZ Sun site.  In February 2019, we contracted for the 141 MW and anticipate such facilities could be in service by mid-2020.  Additionally, in February 2019, APS signed two 20-year power purchase agreements for energy storage totaling 150 MW.  Service under these agreements are scheduled to begin in 2021. &#160;We plan to install at least an additional 660 MW of APS-owned solar plus battery storage and stand-alone battery storage systems by the summer of 2025, with the first 260 MW being procured in 2019 (60 MW on additional AZ Sun sites and 100 MW of solar plus 100 MW of battery storage).&#160;</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-weight:bold;">Regulatory Matters</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-style:italic;font-weight:bold;">Rate Matters.</span><span style="font-family:inherit;font-size:11.5pt;"> &#160;APS needs timely recovery through rates of its capital and operating expenditures to maintain its financial health.&#160; APS&#8217;s retail rates are regulated by the ACC and its wholesale electric rates (primarily for transmission) are regulated by FERC.&#160; See Note 3 for information on APS&#8217;s FERC rates.</span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On June&#160;1, 2016, APS filed an application with the ACC for an annual increase in retail base rates of $165.9 million.

See Note 3 for more information on the RES and the Energy Modernization Plan.</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-style:italic;font-weight:bold;">Demand Side Management.&#160;</span><span style="font-family:inherit;font-size:11.5pt;"> In December&#160;2009, Arizona regulators placed an increased focus on energy efficiency and other demand side management programs to encourage customers to conserve energy, while incentivizing utilities to aid in these efforts that ultimately reduce the demand for energy.&#160; The ACC initiated an Energy Efficiency rulemaking, with a proposed EES of 22% cumulative annual energy savings by 2020.&#160; The 22% figure represents the cumulative reduction in future energy usage through 2020 attributable to energy efficiency initiatives.&#160; This standard became effective on January&#160;1, 2011.  </span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On June 1, 2016, APS filed its 2017 Demand Side Management Implementation Plan ("DSM Plan"), in which APS proposed programs and measures that specifically focus on reducing peak demand, shifting load to off-peak periods and educating customers about strategies to manage their energy and demand.&#160; The requested budget in the 2017 DSM Plan was $62.6 million.&#160; On January 27, 2017, APS filed an updated and modified 2017 DSM Plan that incorporated the proposed $4 million Residential Demand Response, Energy Storage and Load Management Program that was filed with the ACC on December 5, 2016 and requested that the budget for the 2017 DSM Plan be increased to $66.6 million.  On August 15, 2017, the ACC approved the amended 2017 DSM Plan.  </span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On September 1, 2017, APS filed its 2018 DSM Plan, which proposes modifications to the demand side management portfolio to better meet system and customer needs by focusing on peak demand reductions, storage, load shifting and demand response programs in addition to traditional energy savings measures.  The 2018 DSM Plan seeks a reduced requested budget of $52.6 million and requests a waiver of the EES for 2018.  On November 14, 2017, APS filed an amended 2018 DSM Plan, which revised the allocations between budget items to address customer participation levels, but kept the overall budget at $52.6 million.  The ACC has not yet ruled on the APS 2018 amended DSM Plan.  </span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On December 31, 2018, APS filed its 2019 DSM Plan, which requests a budget of $34.1 million and continues APS's focus on DSM strategies such as peak demand reduction, load shifting, storage and electrification strategies.  The ACC has not yet ruled on the APS 2019 DSM Plan.

On December 22, 2017 the Tax Cuts and Jobs Act (&#8220;Tax Act&#8221;) was enacted.&#160; This legislation made significant changes to the federal income tax laws including a reduction in the corporate tax rate from 35% to 21% effective January 1, 2018. </span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;&#160;&#160;&#160;</span></div><div><br/></div><div><div style="line-height:120%;text-align:center;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">58</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;font-size:8pt;"><a style="font-family:inherit;font-size:8pt;" href="#s9C4FF461B8B957B19F176BBFF325F895"><span style="font-family:inherit;font-size:8pt;">Table of Contents </span></a></div></div><div><br/></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On January 8, 2018, APS filed an application with the ACC requesting that the TEAM be implemented in two steps. The first addresses the change in the marginal federal tax rate from 35% to 21% resulting from the Tax Act and, if approved, would reduce rates by $119.1 million annually through an equal cents per kWh credit. APS asked that this decrease become effective February 1, 2018.  On February 22, 2018, the ACC approved the reduction of rates by $119.1 million for the remainder of 2018 through an equal cents per kWh credit applied to all but a small subset of customers who are taking service under specially-approved tariffs. The rate reduction was effective the first billing cycle in March 2018. </span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">The impact of the TEAM, over time, is expected to be earnings neutral.  However, on a quarterly basis, there is a difference between the timing and amount of the income tax benefit and the reduction in revenues refunded through the TEAM related to the lower federal income tax rate. The amount of the benefit of the lower federal income tax rate is based on quarterly pre-tax results, while the reduction in revenues from the prior year due to lower customer rates through the TEAM is based on a per kWh sales credit which follows our seasonal kWh sales pattern and is not impacted by earnings of the Company.</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;padding-bottom:13px;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On August 13, 2018, APS filed a second request with the ACC to return an additional $86.5 million in tax savings to customers. This second request addresses amortization of non-depreciation related excess deferred taxes previously collected from customers.  The ACC has not yet approved this request.</span></div><div style="line-height:120%;padding-bottom:13px;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">Additionally, as part of this second request, APS informed the ACC of its intent to file a third future request to address the amortization of depreciation related excess deferred taxes, as the Company is currently in the process of seeking IRS guidance regarding the amortization method and period applicable to these depreciation related excess deferred taxes.  </span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">The TEAM expressly applies to APS's retail rates with the exception of a small subset of customers taking service under specially-approved tariffs noted above.  As discussed in Note 3, FERC issued an order on May 22, 2018 authorizing APS to provide for the cost reductions resulting from the income tax changes in its wholesale transmission rates.</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">See Note 3 for additional details.  </span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-style:italic;font-weight:bold;">Net Metering.</span><span style="font-family:inherit;font-size:11.5pt;">&#160; &#160;&#160;&#160;&#160;In 2015, the ACC voted to conduct a generic evidentiary hearing on the value and cost of DG to gather information that will inform the ACC on net metering issues and cost of service studies in upcoming utility rate cases.&#160; A hearing was held in April 2016.  On October 7, 2016, an Administrative Law Judge issued a recommendation in the docket concerning the value and cost of DG solar installations.  On December 20, 2016, the ACC completed its open meeting to consider the recommended opinion and order by the Administrative Law Judge.  After making several amendments, the ACC approved the recommended opinion and order by a 4-1 vote.  As a result of the ACC&#8217;s action, effective with APS&#8217;s 2017 Rate Case Decision, the net metering tariff that governs payments for energy exported to the grid from residential rooftop solar systems was replaced by a more formula-driven approach that utilizes inputs from historical wholesale solar power until an avoided cost methodology is developed by the ACC.</span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">As amended, the decision provides that payments by utilities for energy exported to the grid from DG solar facilities will be determined using a resource comparison proxy methodology, a method that is based on the most recent five-year rolling average price that APS pays for utility-scale solar projects, while a forecasted avoided cost methodology is being developed.&#160; The price established by this resource comparison proxy method will be updated annually (between general retail rate cases) but will not be decreased by more than 10% per year.  Once the avoided cost methodology is developed, the ACC will determine in APS's subsequent general retail rate cases which method (or a combination of methods) is appropriate to determine the actual price to be paid by APS for exported distributed energy.</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div><br/></div><div><div style="line-height:120%;text-align:center;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">59</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;font-size:8pt;"><a style="font-family:inherit;font-size:8pt;" href="#s9C4FF461B8B957B19F176BBFF325F895"><span style="font-family:inherit;font-size:8pt;">Table of Contents </span></a></div></div><div><br/></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">In addition, the ACC made the following determinations:</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman; font-size:10pt;"><tr><td style="width:66px;"></td><td></td></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:11.5pt;padding-left:48px;"><span style="font-family:inherit;font-size:11.5pt;">&#8226;</span></div></td><td style="vertical-align:top;"><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">Customers who have interconnected a DG system or submitted an application for interconnection for DG systems prior to September 1, 2017, the date new rates were effective based on APS's 2017 Rate Case Decision, will be grandfathered for a period of 20 years from the date the customer&#8217;s interconnection application was accepted by the utility;</span></div></td></tr></table><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman; font-size:10pt;"><tr><td style="width:66px;"></td><td></td></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:11.5pt;padding-left:48px;"><span style="font-family:inherit;font-size:11.5pt;">&#8226;</span></div></td><td style="vertical-align:top;"><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">Customers with DG solar systems are to be considered a separate class of customers for ratemaking purposes; and</span></div></td></tr></table><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman; font-size:10pt;"><tr><td style="width:66px;"></td><td></td></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:11.5pt;padding-left:48px;"><span style="font-family:inherit;font-size:11.5pt;">&#8226;</span></div></td><td style="vertical-align:top;"><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">Once an export price is set for APS, no netting or banking of retail credits will be available for new DG customers, and the then-applicable export price will be guaranteed for new customers for a period of 10 years.</span></div></td></tr></table><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">This decision of the ACC addresses policy determinations only.

TASC asserted that the ACC improperly ignored the Administrative Procedure Act, failed to give adequate notice regarding the scope of the proceedings, and relied on information that was not submitted as evidence, among other alleged defects.  TASC filed a Notice of Appeal in the Arizona Court of Appeals and filed a Complaint and Statutory Appeal in the Maricopa County Superior Court on March 10, 2017.  As part of the 2017 Settlement Agreement described above, TASC agreed to withdraw these appeals when the ACC decision implementing the 2017 Settlement Agreement is no longer subject to appellate review.</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-style:italic;font-weight:bold;">Subpoena from Arizona Corporation Commissioner Robert Burns.   </span><span style="font-family:inherit;font-size:11.5pt;">On August 25, 2016, Commissioner Burns, individually and not by action of the ACC as a whole, served subpoenas in APS&#8217;s then current retail rate proceeding on APS and Pinnacle West for the production of records and information relating to a range of expenditures from 2011 through 2016.  The subpoenas requested information concerning marketing and advertising expenditures, charitable donations, lobbying expenses, contributions to 501(c)(3) and (c)(4) nonprofits and political contributions.  The return date for the production of information was set as September 15, 2016.

On March 10, 2017, Commissioner Burns filed suit against APS and Pinnacle West in the Superior Court of Arizona for Maricopa County in an effort to enforce his subpoenas.  On March 30, 2017, APS filed a motion to dismiss Commissioner Burns' suit against APS and Pinnacle West.  In response to the motion to dismiss, the court stayed the suit and ordered Commissioner Burns to file a motion to compel the production of the information sought by the subpoenas with the ACC.

All defendants moved to dismiss the amended complaint.  On February 15, 2018, the Superior Court dismissed Commissioner Burns&#8217; amended complaint.  On March 6, 2018, Commissioner Burns filed an objection to the proposed final order from the Superior Court and a motion to further amend his complaint.  The Superior Court permitted Commissioner Burns to amend his complaint to add a claim regarding his attempted investigation into whether his fellow commissioners should have been disqualified from voting on APS&#8217;s 2017 rate case.  Commissioner Burns filed his second amended complaint, and all defendants filed responses opposing the second amended complaint and requested that it be dismissed.  Oral argument occurred in November 2018 regarding the motion to dismiss.  On December 18, 2018, the trial court granted the defendants&#8217; motions to dismiss and entered final judgment on January 18, 2019.

On January 30, 2018, ACC Commissioner Tobin proposed the Energy Modernization Plan, which consists of a series of energy policies tied to clean energy sources such as energy storage, biomass, energy efficiency, electric vehicles, and expanded energy planning through the IRP process.  The Energy Modernization Plan includes replacing the current RES standard with a new standard called the CREST, which incorporates the proposals in the Energy Modernization Plan.  On February 22, 2018, the ACC Staff filed a Notice of Inquiry to further examine the matter.  As a part of this proposal, the ACC voted in March 2018 to direct utilities to develop a comprehensive biomass generation plan to be included in each utility&#8217;s RES Implementation Plan.  On July 5, 2018, Commissioner Tobin&#8217;s office issued a set of draft CREST rules for the ACC&#8217;s consideration.</span></div><div style="line-height:120%;padding-bottom:13px;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">In August 2018, the ACC directed ACC Staff to open a new rulemaking docket which will address a wide range of energy issues, including the Energy Modernization Plan proposals.&#160; The rulemaking will consider possible modifications to existing ACC rules, such as the Renewable Energy Standard, Electric and Gas Energy Efficiency Standards, Net Metering, Resource Planning, and the Biennial Transmission Assessment, as well as the development of new rules regarding forest bioenergy, electric vehicles, interconnection of distributed generation, baseload security, blockchain technology and other technological developments, retail competition, and other energy-related topics.&#160; Workshops on these energy issues are scheduled to be held throughout 2019.

On July 1, 2016, FERC issued an order denying APS&#8217;s request to recover the regulatory asset through its FERC-jurisdictional rates.&#160; APS and SCE completed the termination of the Transmission Agreement on July 6, 2016.  APS made the required payment to SCE and wrote-off the $12 million regulatory asset and charged operating revenues to reflect the effects of this order in the second quarter of 2016. &#160;On July 29, 2016, APS filed for a rehearing with FERC.  In its order denying recovery, FERC also referred to its enforcement division a question of whether the agreement between APS and SCE relating to the settlement of obligations under the Transmission Agreement was a jurisdictional contract that should have been filed with FERC.  On October 5, 2017, FERC issued an order denying APS's request for rehearing.  FERC also upheld its prior determination that the agreement relating to the settlement was a jurisdictional contract and should have been filed with FERC.  APS cannot predict whether or if the enforcement division will take any action.  APS filed an appeal of FERC's July 1, 2016 and October 5, 2017 orders with the United States Court of Appeals for the Ninth Circuit on December 4, 2017.  That proceeding is pending and APS cannot predict the outcome of the proceeding.  </span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-weight:bold;">Financial Strength and Flexibility</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">Pinnacle West and APS currently have ample borrowing capacity under their respective credit facilities, and may readily access these facilities ensuring adequate liquidity for each company.&#160; Capital expenditures will be funded with internally generated cash and external financings, which may include issuances of long-term debt and Pinnacle West common stock.</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-weight:bold;">Other Subsidiaries</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"></span><span style="font-family:inherit;font-size:11.5pt;font-style:italic;font-weight:bold;">Bright Canyon Energy.</span><span style="font-family:inherit;font-size:11.5pt;font-weight:bold;">  </span><span style="font-family:inherit;font-size:11.5pt;">On July&#160;31, 2014, Pinnacle West announced its creation of a wholly-owned subsidiary, BCE.&#160; BCE's focus is on new growth opportunities that leverage the Company&#8217;s core expertise in the electric energy industry.&#160; BCE&#8217;s first initiative is a 50/50 joint venture with BHE U.S. Transmission LLC, a subsidiary of Berkshire Hathaway Energy Company.&#160; The joint venture, named TransCanyon, is pursuing independent transmission opportunities within the eleven states that comprise the Western Electricity Coordinating Council, excluding opportunities related to transmission service that would otherwise be provided under the tariffs of the retail service territories of the venture partners&#8217; utility affiliates.&#160; TransCanyon continues to pursue transmission development opportunities in the western United States consistent with its strategy. </span></div><div><br/></div><div><div style="line-height:120%;text-align:center;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">62</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;font-size:8pt;"><a style="font-family:inherit;font-size:8pt;" href="#s9C4FF461B8B957B19F176BBFF325F895"><span style="font-family:inherit;font-size:8pt;">Table of Contents </span></a></div></div><div><br/></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On March 29, 2016, TransCanyon entered into a strategic alliance agreement with PG&amp;E to jointly pursue competitive transmission opportunities solicited by the CAISO, the operator for the majority of California's transmission grid.

The &#8220;Blue Book&#8221; provides clarification that the intent of the Tax Act was to exclude from the definition of bonus depreciation qualified property any property placed in service by a regulated public utility after December 31, 2017.  As a result, the Company currently does not anticipate recognizing any cash tax benefits related to bonus depreciation for property placed in service on or after January 1, 2018 (See Note 4).

The increase of $159 million in net cash provided is primarily due to higher cash receipts from operating activities as a result of the retail regulatory settlement effective August 19, 2017, higher transmission receipts and higher receipts due to customer growth and higher average effective prices.  These items are partially offset by higher payments for operations and maintenance, income taxes, other taxes and interest.

See Note 7 for additional details.  The assets in the plan are comprised of fixed-income, equity, real estate, and short-term investments.&#160; Future year contribution amounts are dependent on plan asset performance and plan actuarial assumptions.&#160; We made contributions to our pension plan totaling </span><span style="font-family:inherit;font-size:11.5pt;">$50 million</span><span style="font-family:inherit;font-size:11.5pt;"> in </span><span style="font-family:inherit;font-size:11.5pt;">2018</span><span style="font-family:inherit;font-size:11.5pt;">, </span><span style="font-family:inherit;font-size:11.5pt;">$100 million</span><span style="font-family:inherit;font-size:11.5pt;"> in </span><span style="font-family:inherit;font-size:11.5pt;">2017</span><span style="font-family:inherit;font-size:11.5pt;">, and </span><span style="font-family:inherit;font-size:11.5pt;">$100 million</span><span style="font-family:inherit;font-size:11.5pt;"> in </span><span style="font-family:inherit;font-size:11.5pt;">2016</span><span style="font-family:inherit;font-size:11.5pt;">.&#160; The minimum required contributions for the pension plan are </span><span style="font-family:inherit;font-size:11.5pt;">zero</span><span style="font-family:inherit;font-size:11.5pt;"> for the next three years.&#160; We expect to make voluntary contributions up to a total of </span><span style="font-family:inherit;font-size:11.5pt;">$350 million</span><span style="font-family:inherit;font-size:11.5pt;"> during the 2019-2021 period.&#160; With regard to contributions to our other postretirement benefit plan, we did not make a contribution in </span><span style="font-family:inherit;font-size:11.5pt;">2018</span><span style="font-family:inherit;font-size:11.5pt;">.

In 2018, the Company was reimbursed </span><span style="font-family:inherit;font-size:11.5pt;">$72 million</span><span style="font-family:inherit;font-size:11.5pt;"> for prior years retiree medical claims from the other postretirement benefit plan trust assets.</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">Because of plan changes in 2014, the Company sought IRS approval to move approximately </span><span style="font-family:inherit;font-size:11.5pt;">$186 million</span><span style="font-family:inherit;font-size:11.5pt;"> of other postretirement benefit trust assets into a new trust account to pay for active union employee medical costs. In December 2016, FERC approved a methodology for determining the amount of other postretirement benefit trust assets to transfer into a new trust account to pay for active union employee medical costs.  On January 2, 2018, these funds were moved to the new trust account, which is included in the other special use funds on the Consolidated Balance Sheets.  The Company and the IRS executed a final Closing Agreement on March 2, 2018.  The Company made an informational filing with FERC during February 2018.

and our ability to access the markets for liquidity and long-term debt.&#160; The ratings reflect the respective views of the rating agencies, from which an explanation of the significance of their ratings may be obtained.&#160; There is no assurance that these ratings will continue for any given period of time.&#160; The ratings may be revised or withdrawn entirely by the rating agencies if, in their respective judgments, circumstances so warrant.&#160; Any downward revision or withdrawal may adversely affect the market price of Pinnacle West&#8217;s or APS&#8217;s securities and/or result in an increase in the cost of, or limit access to, capital.&#160; Such revisions may also result in substantial additional cash or other collateral requirements related to certain derivative

style="font-family:inherit;font-size:11.5pt;">Regulatory accounting allows for the actions of regulators, such as the ACC and FERC, to be reflected in our financial statements.&#160; Their actions may cause us to capitalize costs that would otherwise be included as an expense in the current period by unregulated companies.&#160; Regulatory assets represent incurred costs that have been deferred because they are probable of future recovery in customer rates.&#160; Regulatory liabilities generally represent amounts collected in rates to recover costs expected to be incurred in the future or amounts collected in excess of costs incurred and are refundable to customers.  Management continually assesses whether our regulatory assets are probable of future recovery by considering factors such as applicable regulatory environment changes and recent rate orders to other regulated entities in the same jurisdiction.&#160; This determination reflects the current political and regulatory climate in Arizona and is subject to change in the future.&#160; If future recovery of costs ceases to be probable, the assets would be written off as a charge in current period earnings, except for pension benefits which would be charged to OCI and result in lower future earnings.&#160; We had $1,510 million of regulatory assets and $2,492 million of regulatory liabilities on the Consolidated Balance Sheets at December&#160;31, 2018.</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">See Notes 1 and 3 for more information.</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-weight:bold;">Pensions and Other Postretirement Benefit Accounting</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">Changes in our actuarial assumptions used in calculating our pension and other postretirement benefit liability and expense can have a significant impact on our earnings and financial position.&#160; The most relevant actuarial assumptions are the discount rate used to measure our liability and net periodic cost, the expected long-term rate of return on plan assets used to estimate earnings on invested funds over the long-term, the mortality assumptions, and the assumed healthcare cost trend rates.&#160; We review these assumptions on an annual basis and adjust them as necessary.</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On January 1, 2018, we adopted new accounting standard ASU 2017-07, Compensation-Retirement Benefits: Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.

We utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs.&#160; The significance of a particular input determines how the instrument is classified in a fair value hierarchy.&#160; The determination of fair value sometimes requires subjective and complex judgment.&#160; Our assessment of the inputs and the significance of a particular input to fair value measurement may affect the valuation of the instruments and their placement within a fair value hierarchy.&#160; Actual results could differ from our estimates of fair value.&#160; See Note 1 for a discussion of accounting policies and Note 13 for fair value measurement disclosures.</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-weight:bold;">Asset Retirement Obligations</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">We recognize an ARO for the future decommissioning or retirement of our tangible long-lived assets for which a legal obligation exists. The ARO liability represents an estimate of the fair value of the current obligation related to decommissioning and the retirement of those assets. ARO measurements inherently involve uncertainty in the amount and timing of settlement of the liability. We use an expected cash flow approach to measure the amount we recognize as an ARO. This approach applies probability weighting to discounted future cash flow scenarios that reflect a range of possible outcomes. The scenarios consider settlement of the ARO at the expiration of the asset&#8217;s current license or lease term and expected decommissioning dates. The fair value of an ARO is recognized in the period in which it is incurred. The associated asset retirement costs are capitalized as part of the carrying value of the long-lived asset and are depreciated over the life of the related assets. In addition, we accrete the ARO liability to reflect the passage of time. Changes in these estimates and assumptions could materially affect the amount of the recorded ARO for these assets. In accordance with GAAP accounting, APS accrues removal costs for its regulated utility assets, even if there is no legal obligation for removal. </span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">AROs as of December 31, 2018 are described further in Note 11.</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-weight:bold;">Income Taxes</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;padding-bottom:13px;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">Our income tax expense, deferred tax assets and liabilities, and liabilities for unrecognized tax benefits reflect management&#8217;s best estimate of current and future taxes to be paid.  </span></div><div style="line-height:120%;padding-bottom:13px;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On December 22, 2017, the Tax Act was enacted, and is generally effective January 1, 2018. This legislation made significant changes to the federal income tax laws. Changes which impact the Company include, but are not limited to, a reduction in the corporate tax rate to 21%, revisions to the rules related to tax bonus depreciation, limitations on interest deductibility and an associated exception for certain public utility property, and requirements that certain excess deferred tax amounts of regulated utilities be normalized. </span></div><div style="line-height:120%;padding-bottom:13px;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">Deferred tax assets or liabilities are recognized for the estimated future tax effects attributable to temporary differences between the financial statement basis and the tax basis of assets and liabilities as well as tax credit carryforwards and net operating loss carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period the change is enacted.

Interpretations and guidance surrounding income tax laws and regulations change over time. Tax positions taken by Pinnacle West on its income tax returns that are recognized in the financial statements must satisfy a "more likely than not" recognition threshold, assuming that the position will be sustained upon examination by taxing authorities with full knowledge of all relevant information, including resolutions of any related appeals or litigation processes, on the basis of the technical merits.  Additional guidance may be issued through legislation, Treasury regulations, or other technical guidance, which may materially affect amounts the Company has recognized in its financial statements.</span></div><div style="line-height:120%;padding-bottom:13px;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">We record unrecognized tax benefits for tax positions that may not satisfy this "more likely than not" recognition threshold as liabilities in accordance with generally accepted accounting principles.  These liabilities are adjusted when management judgment changes as a result of the evaluation of new information not previously available. These changes will be reflected as an increase or decrease to income tax expense in the period in which new information is available.</span></div><div><a

Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk.

A company&#8217;s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company&#8217;s assets that could have a material effect on the financial statements. </span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;&#160;&#160;&#160;</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.

Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions. </span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div><br/></div><div><div style="line-height:120%;text-align:center;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">97</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;font-size:8pt;"><a style="font-family:inherit;font-size:8pt;" href="#s9C4FF461B8B957B19F176BBFF325F895"><span style="font-family:inherit;font-size:8pt;">Table of Contents </span></a></div></div><div><br/></div><div style="line-height:120%;padding-bottom:10px;text-align:justify;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-weight:bold;">Definition and Limitations of Internal Control over Financial Reporting</span><span style="font-family:inherit;font-size:9pt;font-weight:bold;"> </span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">A company&#8217;s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company&#8217;s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company&#8217;s assets that could have a material effect on the financial statements. </span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;&#160;&#160;&#160;</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.

Minor changes were made in the description of certain income statement line items and the amounts presented in the comparable prior period also changed by immaterial amounts due to the change from a utility to a non-utility format and also from the adoption of the new accounting guidance for net periodic pension cost and net periodic postretirement benefit cost.

Revenues related to the sale of electricity are generally recognized 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.  We obtain customers' meter data on a systematic basis throughout the month, and generally bill customers within a month from when service was provided. Customers are generally required to pay for services within 15 days of when the services are billed. Unbilled revenues are estimated by applying an average revenue/kWh by customer class to the number of estimated kWhs delivered but not billed.  Differences historically between the actual and estimated unbilled revenues are immaterial.

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.&#160; These agreements have a history of uninterrupted renewal that APS expects to continue.&#160; As a result, APS cannot reasonably estimate the fair value of the asset retirement obligation related to such transmission and distribution assets.

May 2014, a new revenue recognition accounting standard was issued. This standard provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance. Since the issuance of the new revenue standard, additional guidance was issued to clarify certain aspects of the new revenue standard, including principal versus agent considerations, identifying performance obligations, and other narrow scope improvements. The new revenue standard, and related amendments, became effective for us on January 1, 2018.  The standard may be adopted using a full retrospective application or a simplified transition method that allows entities to record a cumulative effect adjustment in retained earnings at the date of initial application.</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">We adopted this standard and related amendments on January 1, 2018 using the modified retrospective transition approach.

The guidance is intended to eliminate diversity in practice in how entities classify these specific activities between cash flows from operating activities, investing activities and financing activities. The specific activities addressed include debt prepayments and extinguishment costs, proceeds from the settlement of insurance claims, proceeds from corporate-owned life insurance policies, and other activities. The standard also addresses how entities should apply the predominance principle when a transaction includes separately identifiable cash flows.  The new standard was effective for us, and was adopted on January 1, 2018, using a retrospective transition method.  The adoption of this guidance did not have a significant impact on our financial statements, as either our statement of cash flow presentation is consistent with the new prescribed guidance or we do not have significant activities relating to the specific transactions that are addressed by the new standard.</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-weight:bold;">ASU 2016-18, Statement of Cash Flows: Restricted Cash</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">In November 2016, a new accounting standard was issued that clarifies how restricted cash and restricted cash equivalents should be presented on the statement of cash flows.

The presentation changes  require net benefit costs to be disaggregated on the income statement by the various components that comprise these costs. Specifically, only the service cost component is eligible for presentation as an operating income item, and all other cost components are now presented as non-operating items. This presentation change was applied retrospectively. Furthermore, the new standard allows only the service cost component to be eligible for capitalization. The change in capitalization requirements was applied prospectively.

As a result of adopting this standard we have presented the non-service cost components of net benefits costs in other income instead of operating income.  Prior year non-service cost components have also been reclassified to conform to this new presentation.  We elected to apply the practical expedient guidance.  As such, prior period costs have been estimated based on amounts previously disclosed in our pension and other postretirement benefit plan notes.  The changes impacting capitalization have been adopted prospectively.

To determine which implementation costs should be capitalized, the new guidance aligns the accounting with existing guidance pertaining to internal-use software. As a result of this new standard, certain cloud computing service arrangement implementation costs will now be subject to capitalization and amortized on a straight-line basis over the cloud computing service arrangement term. The new standard is effective for us on January 1, 2020, with early application permitted, and may be applied using either a retrospective or prospective transition approach.

The subpoenas requested information concerning marketing and advertising expenditures, charitable donations, lobbying expenses, contributions to 501(c)(3) and (c)(4) nonprofits and political contributions.  The return date for the production of information was set as September 15, 2016.

Neither APS nor Pinnacle West produced the information requested and instead objected to the subpoena.  On March 10, 2017, Commissioner Burns filed suit against APS and Pinnacle West in the Superior Court of Arizona for Maricopa County in an effort to enforce his subpoenas.  On March 30, 2017, APS filed a motion to dismiss Commissioner Burns' suit against APS and Pinnacle West.

On March 6, 2018, Commissioner Burns filed an objection to the proposed final order from the Superior Court and a motion to further amend his complaint.  The Superior Court permitted Commissioner Burns to amend his complaint to add a claim regarding his attempted investigation into whether his fellow commissioners should have been disqualified from voting on APS&#8217;s 2017 rate case. Commissioner Burns filed his second amended complaint, and all defendants filed responses opposing the second amended complaint and requested that it be dismissed.  Oral argument occurred in November 2018 regarding the motion to dismiss.  On December 18, 2018, the trial court granted the defendants&#8217; motions to dismiss and entered final judgment on January 18, 2019.

On February 22, 2018, the ACC Staff filed a Notice of Inquiry to further examine the matter. As a part of this proposal, the ACC voted in March 2018 to direct utilities to develop a comprehensive biomass generation plan to be included in each utility&#8217;s RES Implementation Plan.

On December 20, 2018, the Joint Committee on Taxation (&#8220;JCT&#8221;)  released the general explanation of the Tax Act. The document - commonly referred to as the "Blue Book" - provides a comprehensive technical description of the Tax Act and includes the legislative intent of Congress with respect to the changes made by provisions of the Tax Act. The &#8220;Blue Book&#8221; provides clarification that the intent of the Tax Act was to exclude from the definition of bonus depreciation qualified property any property placed in service by a regulated public utility after December 31, 2017.  In a footnote, the JCT indicated that a technical correction bill may be necessary to reflect this intent.  </span></div><div style="line-height:120%;text-indent:48px;font-size:11pt;"><span style="font-family:inherit;font-size:11pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11pt;"><span style="font-family:inherit;font-size:11pt;">Management recognizes tax positions which it believes are "more likely than not" to be sustained upon examination. In applying this "more likely than not" assessment, the Company is required to consider the technical merits of a position, including legislative intent.  As a result, while no legislation has been passed which clarifies the ambiguities related to bonus depreciation for property placed in service on or after January 1, 2018, the Company currently believes the continued availability of bonus depreciation is not "more likely than not" to be sustained upon examination. As a result, the Company has not recognized any current or deferred tax benefits related to bonus depreciation for property placed in service on or after January 1, 2018.</span></div><div style="line-height:120%;text-indent:48px;font-size:11pt;"><span style="font-family:inherit;font-size:11pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11pt;"><span style="font-family:inherit;font-size:11pt;">For the quarter ending March 31, 2018, the Company early adopted &#160;ASU 2018-02, Income Statement-Reporting Comprehensive Income: Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income and elected to reclassify the income tax effects of the Tax Act on items within accumulated other comprehensive income to retained earnings.

investment policy statements (&#8220;IPS&#8221;) for the pension and the other postretirement benefit plans&#8217; assets.

trust assets relative to the benefit obligations.&#160; To achieve this objective, the plan&#8217;s investment policy provides for mixes of investments including long-term fixed income assets and return-generating assets.&#160; The target allocation between return-generating and long-term fixed income assets is defined in the IPS and is a function of the plan&#8217;s funded status.&#160; The plan&#8217;s funded status is reviewed on at least a monthly basis.</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span

value of long-term fixed income assets, also known as liability-hedging assets, are intended to offset changes in the benefit obligations due to changes in interest rates.&#160; Long-term fixed income assets consist primarily of fixed income debt securities issued by the U.S. Treasury and other government agencies, U.S. Treasury Futures Contracts, and fixed income debt securities issued by corporations.&#160; Long-term fixed income assets may also include interest rate swaps, and other instruments.</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span

assets are intended to provide a reasonable long-term rate of investment return with a prudent level of volatility.&#160; Return-generating assets are composed of U.S. equities, international equities, and alternative investments.&#160; International equities include investments in both developed and emerging markets.&#160; Alternative investments include investments in real estate, private equity and various other strategies.&#160; The plan may also hold investments in return-generating assets by holding securities in partnerships, common and collective trusts and mutual

The rule regulates CCR as a non-hazardous waste under Subtitle D of the Resource Conservation and Recovery Act ("RCRA") and establishes national minimum criteria for existing and new CCR landfills and surface impoundments and all lateral expansions consisting of location restrictions, design and operating criteria, groundwater monitoring and corrective action, closure requirements and post closure care, and recordkeeping, notification, and internet posting requirements.  The rule generally requires any existing unlined CCR surface impoundment that is contaminating groundwater above a regulated constituent&#8217;s groundwater protection standard to stop receiving CCR and either retrofit or close, and further requires the closure of any CCR landfill or surface impoundment that cannot meet the applicable performance criteria for location restrictions or structural integrity.  Such closure requirements are deemed "forced closure" or "closure for cause" of unlined surface impoundments, and are the subject of recent regulatory and judicial activities described below.</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On December 16, 2016, President Obama signed the Water Infrastructure Improvements for the Nation ("WIIN") Act into law, which contains a number of provisions requiring EPA to modify the self-implementing provisions of the Agency's current CCR rules under Subtitle D.  Such modifications include new EPA authority to directly enforce the CCR rules through the use of administrative orders and providing states, like Arizona, where the Cholla facility is located, the option of developing CCR disposal unit permitting programs, subject to EPA approval.  For facilities in states that do not develop state-specific permitting programs, EPA is required to develop a federal permit program, pending the availability of congressional appropriations.  By contrast, for facilities located within the boundaries of Native American tribal reservations, such as the Navajo Nation, where the Navajo Plant and Four Corners facilities are located, EPA is required to develop a federal permit program regardless of appropriated funds.  </span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">ADEQ has initiated a process to evaluate how to develop a state CCR permitting program that would cover electric generating units ("EGUs"), including Cholla.  While APS has been working with ADEQ on the development of this program, we are unable to predict when Arizona will be able to finalize and secure EPA approval for a state-specific CCR permitting program.  With respect to the Navajo Nation, APS has sought clarification as to when and how EPA would be initiating permit proceedings for facilities on the reservation, including Four Corners.  We are unable to predict at this time when EPA will be issuing CCR management permits for the facilities on the Navajo Nation.  At this time, it remains unclear how the CCR provisions of the WIIN Act will affect APS and its management of CCR.  </span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">Based upon utility industry petitions for EPA to reconsider the RCRA Subtitle D regulations for CCR, which were premised in part on the CCR provisions of the 2016 WIIN Act, on September 13, 2017 EPA agreed to evaluate whether to revise these federal CCR regulations.  On July 17, 2018, EPA finalized a revision to its RCRA Subtitle D regulations for CCR, the "Phase I, Part I" revision to its CCR regulations, deferring for future action a number of other proposed changes contemplated in a March 1, 2018 proposal.  For the final rule issued on July 17, 2018, EPA established nationwide health-based standards for certain constituents of CCR subject to groundwater corrective action and delayed the closure deadlines for certain unlined CCR surface impoundments by 18 months (for example, those disposal units required to undergo forced closure).  These changes to the federal regulations governing CCR disposal are unlikely to have a material impact on APS.  As for those aspects of the March 2018 rulemaking proposal for which EPA has yet to take final action, it remains unclear which specific provisions of the federal CCR rules will ultimately be modified, how they will be modified, or when such modification will occur.  </span></div></ix:continuation><div><br/></div><div><div style="line-height:120%;text-align:center;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">154</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;text-align:left;font-size:8pt;"><a style="font-family:inherit;font-size:8pt;" href="#s9C4FF461B8B957B19F176BBFF325F895"><span style="font-family:inherit;font-size:8pt;">Table of Contents </span></a></div><div style="line-height:120%;text-align:center;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:center;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-weight:bold;">COMBINED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS</span></div><div style="line-height:120%;text-align:left;font-size:8pt;"><span style="font-family:inherit;font-size:8pt;"><br/></span></div></div><div><br/></div><ix:continuation id="TextSelection-11DD24698A55D4CCD0F6EB7E6EF9E417-6" continuedAt="TextSelection-11DD24698A55D4CCD0F6EB7E6EF9E417-7"><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">Pursuant to a June 24, 2016 order by the D.C.

EPA is not required to take final action approving the inclusion of boron.&#160; Should EPA take final action adding boron to the list of groundwater constituents that might trigger corrective action, any resulting corrective action measures may increase APS's costs of compliance with the CCR rule at our coal-fired generating facilities.&#160; At this time APS cannot predict the eventual results of this rulemaking proceeding concerning boron.</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On August 21, 2018, the D.C. Circuit Court issued its decision on the merits in this litigation.  The Court upheld the legality of EPA&#8217;s CCR regulations, though it vacated and remanded back to EPA a number of specific provisions, which are to be corrected in accordance with the Court&#8217;s order.  Among the issues affecting APS&#8217;s management of CCR, the D.C. Circuit&#8217;s decision vacated and remanded those provisions of the EPA CCR regulations that allow for the operation of unlined CCR surface impoundments, even where those unlined impoundments have not otherwise violated a regulatory location restriction or groundwater protection standard (i.e., otherwise triggering forced closure).  At this time, it remains unclear how this D.C. Circuit Court decision will affect APS&#8217;s operations or any financial impacts, as EPA has yet to take regulatory action on remand to revise its 2015 CCR regulations consistent with the Court&#8217;s order. </span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">Based on this decision, on December 17, 2018, certain environmental groups filed an emergency motion with the D.C.

In response, EPA filed a motion to remand but not vacate that deadline extension regulation.  We cannot predict the outcome of the D.C.

On August 3, 2015, EPA finalized carbon pollution standards for EGUs, the "Clean Power Plan".  On October 10, 2017, EPA issued a proposal to repeal the Clean Power Plan and proposed replacement regulations on August 21, 2018.

In contrast with the Clean Power Plan, EPA's proposed "Affordable Clean Energy Rule" would not involve utility-level generation dispatch shifting away from coal-fired generation and toward renewable energy resources and natural gas-fired combined cycle power plants.  In addition, to address the New Source Review ("NSR") implications of power plant upgrades potentially necessary to achieve compliance with the proposed Affordable Clean Energy Rule standards, EPA also proposed to revise EPA's NSR regulations to more readily authorize the implementation of EGU efficiency upgrades.</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">We cannot predict the outcome of EPA's regulatory actions related to the August 2015 carbon pollution standards for EGU's, including any actions related to EPA's repeal proposal for the Clean Power Plan or additional rulemaking actions to approve the EPA's recently proposed Affordable Clean Energy Rule.

assessment of the inputs and the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of fair value assets and liabilities as well as their

These include valuation adjustments for liquidity and credit risks.&#160; The liquidity valuation adjustment represents the cost that would be incurred if all unmatched positions were closed out or hedged.&#160; The credit valuation adjustment represents estimated credit losses on our net exposure to counterparties, taking into account netting agreements, expected default experience for the credit rating of the counterparties and the overall diversification of the portfolio.&#160;

transportation costs of electricity, natural gas, coal, emissions allowances and interest rates.&#160; Risks associated with market volatility are managed by utilizing various physical and financial derivative instruments, including futures, forwards, options and swaps.&#160; As part of our overall risk management program, we may use derivative instruments to hedge purchases and sales of electricity and fuels.&#160; Derivative instruments that meet certain hedge accounting criteria may be designated as cash flow hedges and are used to limit our exposure to cash flow variability on forecasted transactions.&#160; The changes in market value of such instruments have a high correlation to price changes in the hedged transactions.&#160; Derivative instruments are also entered into for economic hedging purposes.&#160; While economic hedges may mitigate exposure to fluctuations in commodity prices, these instruments have not been designated as accounting hedges.&#160; Contracts that have the same terms (quantities, delivery points and delivery periods) and for which power does not flow are netted, which reduces both revenues and fuel and purchased power costs in our

As of </span><span style="font-family:inherit;font-size:11.5pt;">December&#160;31, 2018</span><span style="font-family:inherit;font-size:11.5pt;">, Pinnacle West has no counterparties with positive exposures of greater than 10% of risk management assets.  Our risk management process assesses and monitors the financial exposure of all counterparties.&#160; Despite the fact that the great majority of trading counterparties' debt is rated as investment grade by the credit rating agencies, there is still a possibility that one or more of these counterparties 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.&#160; We maintain credit policies that we believe minimize overall credit risk to within acceptable limits.&#160; 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.&#160; 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.&#160; Valuation adjustments are established representing our estimated credit losses on our overall exposure to counterparties.</span></div><div

features including, among other things, investment grade credit rating provisions, credit-related cross-default provisions, and adequate assurance provisions.&#160; Adequate assurance provisions allow a counterparty with reasonable grounds for uncertainty to demand additional collateral based on subjective events and/or conditions.&#160; 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&#160;&amp;

January&#160;1, 2018, we adopted new revenue guidance in ASU 2014-09 and related amendments. The new revenue guidance requires entities to recognize revenue when control of the promised good or service is transferred to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. We applied the new guidance using the modified retrospective method applied to contracts which were not completed as of January 1, 2018. The adoption of the new revenue guidance resulted in expanded disclosures but otherwise did not have a material impact on our financial statements. New revenue disclosures required by the standard are included below, and in Note 1.  See Note 2 for additional information regarding the new accounting standard.  </span></div></ix:continuation><div><br/></div><div><div

Earnings impacts of actions of the Arizona Corporation Commission ("ACC") in the PNW Plan year are excluded.</font></div><div style="line-height:120%;font-size:11.5pt;"><font style="font-family:inherit;font-size:11.5pt;"><br></font></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><font style="font-family:inherit;font-size:11.5pt;">Mr. Brandt&#8217;s incentive award opportunity is based 62.5% on Pinnacle West&#8217;s 2019 earnings, and 37.5% on the achievement of performance goals established for all business units of APS. Mr.&#160;Brandt has an award opportunity of 50% of his base salary if the threshold earnings level is met. If Pinnacle West&#8217;s 2019 earnings exceed the threshold level, Mr. Brandt&#8217;s award opportunity increases proportionately by up to an additional 75% of his base salary. To the extent certain business unit performance goals are met, Mr. Brandt has a further award opportunity of up to 75% of base salary. The business unit performance indicators for Mr.&#160;Brandt are in the functional areas of customer service, transmission and distribution, fossil generation, corporate resources and performance of the Palo Verde Generating Station. In no event may Mr.&#160;Brandt&#8217;s award exceed 200% of his base salary.</font></div><div style="line-height:120%;font-size:11.5pt;"><font style="font-family:inherit;font-size:11.5pt;"><br></font></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><font style="font-family:inherit;font-size:11.5pt;">The award opportunities for Mr.&#160;Hatfield under the APS Plan are based on the achievement of specified 2019 APS earnings levels and specified business unit performance goals.&#160; Mr. Hatfield has a target award opportunity of up to 75% of his base salary.&#160; Mr.&#160;Hatfield may earn less or more than the target amount, up to a maximum award opportunity of 150% of base salary, depending on the achievement of the earnings and business unit performance goals separately or in combination, and before adjustment for individual performance.&#160; The business unit performance indicators that will be considered for Mr.&#160;Hatfield are derived from the APS critical areas of focus, as provided in its &#8220;Core&#8221; strategic framework, in the functional areas of&#160;employees, operational excellence, and shareholder value.&#160; The Committee may adjust targets under the APS Plan to reflect unanticipated events or unusual or nonrecurring adjustments to earnings that arise in the APS Plan year, including ACC rate-related impacts on earnings.</font></div><div style="line-height:120%;font-size:11.5pt;"><font style="font-family:inherit;font-size:11.5pt;"><br></font></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><font style="font-family:inherit;font-size:11.5pt;">The award opportunity for Mr.&#160;Bement under the Palo Verde Plan is based on the achievement of specified 2019 APS earnings levels and specified business unit performance goals. No incentive payment will be awarded to Mr. Bement under the APS earnings portion of the Palo Verde Plan unless Palo Verde achieves specified business unit performance goals and APS achieves a target threshold earnings level.&#160; The business unit performance indicators for Mr.&#160;Bement under the Palo Verde Plan are in the functional areas of employees, operational excellence, performance improvement and shareholder value.&#160; Mr.&#160;Bement has a threshold award opportunity of 18.8% of his base salary, a target of 75% of his base salary, and up to a maximum of 150% of his base salary, depending on the achievement of the earnings and business unit performance goals, separately or in combination, and before adjustment for individual performance.</font></div><div style="line-height:120%;font-size:11.5pt;"><font style="font-family:inherit;font-size:11.5pt;"><br></font></div><div><br></div><div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div></div><hr style="page-break-after:always"><div><div style="line-height:120%;text-align:right;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-weight:bold;">Exhibit 10.6.4</font></div></div><div><br></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><font style="font-family:inherit;font-size:11.5pt;">Any awards for Messrs.&#160;Brandt, Hatfield and Bement are subject to potential forfeiture or recovery to the extent required by the Company&#8217;s clawback policy.</font></div><div style="line-height:120%;font-size:11.5pt;"><font style="font-family:inherit;font-size:11.5pt;"><br></font></div><div><br></div><div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div></div>	</body>

BCE is a subsidiary that was formed in 2014 that focuses on growth opportunities that leverage the Company's core expertise in the electric energy industry.  BCE is currently pursuing transmission opportunities through a joint venture arrangement.  4CA is a subsidiary that was formed in 2016 as a result of the purchase of El Paso's &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;7%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; interest in Four Corners.

Beginning in the quarter ended March 31, 2018, APS changed the format of presentation of its Consolidated Statements of Income from a utility ratemaking format to a commercial format.  Minor changes were made in the description of certain income statement line items and the amounts presented in the comparable prior period also changed by immaterial amounts due to the change from a utility to a non-utility format and also from the adoption of the new accounting guidance for net periodic pension cost and net periodic postretirement benefit cost.  In addition, the prior year amounts were reclassified to conform to the current year presentation for the other special use funds in the investment and other assets section on the Consolidated Balance Sheets.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:96px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;Accounting Records and Use of Estimates&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;Our accounting records are maintained in accordance with accounting principles generally accepted in the United States of America ("GAAP").&#160; 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.&#160; Actual results could differ from those estimates.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:center;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;Regulatory Accounting&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;APS is regulated by the ACC and FERC.&#160; The accompanying financial statements reflect the rate-making policies of these commissions.&#160; As a result, we capitalize certain costs that would be included as expense in the current period by unregulated companies.&#160; Regulatory assets represent incurred costs that have been deferred because they are probable of future recovery in customer rates.  Regulatory liabilities generally represent amounts collected in rates to recover costs expected to be incurred in the future or amounts collected in excess of costs incurred and are refundable to customers. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;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 APS or other regulated entities in the same jurisdiction.&#160; This determination reflects the current political and regulatory climate in Arizona and is subject to change in the future.&#160; If future recovery of costs ceases to be probable, the assets would be written off as a charge in current period earnings.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;See Note &lt;/span&gt;&lt;span style="font-size:11.5pt;"&gt;3&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; for additional information.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;Electric Revenues&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;We derive electric revenues primarily from sales of electricity to our regulated Native Load customers. Revenues related to the sale of electricity are generally recognized 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.  We obtain customers' meter data on a systematic basis throughout the month, and generally bill customers within a month from when service was provided. Customers are generally required to pay for services within 15 days of when the services are billed. Unbilled revenues are estimated by applying an average revenue/kWh by customer class 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.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;On January 1, 2018, we adopted new revenue guidance ASU 2014-09, Revenue from contracts with customers, accordingly our 2018 electric revenues primarily consist of activities that now are classified as revenues from contracts with customers. Our electric revenues generally represent a single performance obligation delivered over time. We have elected to apply the invoice practical expedient and, as such, we recognize revenue based on the amount to which we have a right to invoice for services performed. See Note 2.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;Revenues from our Native Load customers and non-derivative instruments are reported on a gross basis on Pinnacle West&#x2019;s Consolidated Statements of Income.&#160; In the electricity business, some contracts to purchase electricity are netted against other contracts to sell electricity.  This is called a "book-out" and usually occurs for contracts that have the same terms (quantities, delivery points and delivery periods) and for which &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;power does not flow. We net these book-outs, which reduces both wholesale revenues and fuel and purchased power costs.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;Some of our cost recovery mechanisms are alternative revenue programs.&#160; For alternative revenue programs that meet specified accounting criteria, we recognize revenues when the specific events permitting billing of the additional revenues have been completed.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span

style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;The allowance for doubtful accounts represents our best estimate of existing accounts receivable that will ultimately be uncollectible.&#160; The allowance is calculated by applying estimated write-off factors to various classes of outstanding receivables, including accrued utility revenues.&#160; The write-off factors used to estimate uncollectible accounts are based upon consideration of both historical collections experience and management&#x2019;s best estimate of future collections success given the existing collections environment.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span

Some of APS&#x2019;s transmission and distribution assets have asset retirement obligations because they are subject to right of way and easement agreements that require final removal.&#160; These agreements have a history of uninterrupted renewal that APS expects to continue.&#160; As a result, APS cannot reasonably estimate the fair value of the asset retirement obligation related to such transmission and distribution assets.  Additionally, APS has aquifer protection permits for some of its generation sites that require the closure of certain facilities at those sites.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;See Note &lt;/span&gt;&lt;span style="font-size:11.5pt;"&gt;11&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;

APS materials, supplies and fossil fuel inventories are carried at the lower of weighted-average cost or market, unless evidence indicates that the weighted-average cost (even if in excess of market) will be recovered.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;Fair Value Measurements&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;We apply recurring fair value measurements to cash equivalents, derivative instruments, investments held in the nuclear decommissioning trust and other special use funds.  On an annual basis, we apply fair value measurements to plan assets&#160;held in our retirement and other benefits plans.  Due to the short-term nature of short-term borrowings, the carrying values of these instruments approximate fair value.&#160; Fair value measurements may also be applied on a nonrecurring basis to other assets and liabilities in certain circumstances such as impairments.&#160; We also disclose fair value information for our long-term debt, which is carried at amortized cost (see Note 6).&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;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 which we can access for the asset or liability in an orderly transaction between willing market participants on the measurement date.&#160; Inputs to fair value may include observable and unobservable data.&#160; We maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;We determine fair market value using observable inputs such as actively-quoted prices for identical instruments when available.&#160; When actively-quoted prices are not available for the identical instruments, we use other observable inputs, such as prices for similar instruments, other corroborative market information, or prices provided by other external sources.&#160; For options, long-term contracts and other contracts for which observable price data are not available, we use models and other valuation methods, which may incorporate unobservable inputs to determine fair market value.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:center;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;The use of models and other valuation methods to determine fair market value often requires subjective and complex judgment.&#160; Actual results could differ from the results estimated through application of these methods.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;See Note &lt;/span&gt;&lt;span style="font-size:11.5pt;"&gt;13&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;

We manage risks associated with market volatility by utilizing various physical and financial instruments including futures, forwards, options and swaps.&#160; As part of our overall risk management program, we may use derivative instruments to hedge purchases and sales of electricity and fuels.&#160; The changes in market value of such contracts have a high correlation to price changes in the hedged transactions.&#160; We also enter into derivative instruments for economic hedging purposes.&#160; Contracts that have the same terms (quantities, delivery points and delivery periods) and for which power does not flow are netted, which reduces both revenues and fuel and purchased power expenses in our Consolidated Statements of Income, but does not impact our financial condition, net income or cash flows.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;We account for our derivative contracts in accordance with derivatives and hedging guidance, which requires all derivatives not qualifying for a scope exception to be measured at fair value on the balance sheet as either assets or liabilities.&#160; Transactions with counterparties that have master netting arrangements are reported net on the balance sheet.&#160; See Notes &lt;/span&gt;&lt;span style="font-size:11.5pt;"&gt;2&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;

Contingent losses and environmental liabilities are recorded when it is determined that it is probable that a loss has occurred and the amount of the loss can be reasonably estimated.&#160; When a range of the probable loss exists and no amount within the range is a better estimate than any other amount, Pinnacle West and APS record a loss contingency at the minimum amount in the range.&#160; Unless otherwise required by GAAP, legal fees are expensed as incurred.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;Retirement Plans and Other Postretirement Benefits&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;Pinnacle West sponsors a qualified defined benefit and account balance pension plan for the employees of Pinnacle West and its subsidiaries.&#160; We also sponsor another postretirement benefit plan for the employees of Pinnacle West and its subsidiaries that provides medical and life insurance benefits to retired employees.&#160; Pension and other postretirement benefit expense are determined by actuarial valuations, based on assumptions that are evaluated annually.&#160;

BCE is a subsidiary that was formed in 2014 that focuses on growth opportunities that leverage the Company's core expertise in the electric energy industry.  BCE is currently pursuing transmission opportunities through a joint venture arrangement.  4CA is a subsidiary that was formed in 2016 as a result of the purchase of El Paso's &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;7%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; interest in Four Corners.

Beginning in the quarter ended March 31, 2018, APS changed the format of presentation of its Consolidated Statements of Income from a utility ratemaking format to a commercial format.  Minor changes were made in the description of certain income statement line items and the amounts presented in the comparable prior period also changed by immaterial amounts due to the change from a utility to a non-utility format and also from the adoption of the new accounting guidance for net periodic pension cost and net periodic postretirement benefit cost.  In addition, the prior year amounts were reclassified to conform to the current year presentation for the other special use funds in the investment and other assets section on the Consolidated Balance Sheets.</us-gaap:BasisOfAccountingPolicyPolicyTextBlock>

Revenues related to the sale of electricity are generally recognized 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.  We obtain customers' meter data on a systematic basis throughout the month, and generally bill customers within a month from when service was provided. Customers are generally required to pay for services within 15 days of when the services are billed. Unbilled revenues are estimated by applying an average revenue/kWh by customer class 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.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;On January 1, 2018, we adopted new revenue guidance ASU 2014-09, Revenue from contracts with customers, accordingly our 2018 electric revenues primarily consist of activities that now are classified as revenues from contracts with customers. Our electric revenues generally represent a single performance obligation delivered over time. We have elected to apply the invoice practical expedient and, as such, we recognize revenue based on the amount to which we have a right to invoice for services performed. See Note 2.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;Revenues from our Native Load customers and non-derivative instruments are reported on a gross basis on Pinnacle West&#x2019;s Consolidated Statements of Income.&#160; In the electricity business, some contracts to purchase electricity are netted against other contracts to sell electricity.  This is called a "book-out" and usually occurs for contracts that have the same terms (quantities, delivery points and delivery periods) and for which &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;power does not flow.

Some of APS&#x2019;s transmission and distribution assets have asset retirement obligations because they are subject to right of way and easement agreements that require final removal.&#160; These agreements have a history of uninterrupted renewal that APS expects to continue.&#160; As a result, APS cannot reasonably estimate the fair value of the asset retirement obligation related to such transmission and distribution assets.  Additionally, APS has aquifer protection permits for some of its generation sites that require the closure of certain facilities at those sites.</us-gaap:AssetRetirementObligationsPolicy>

This standard provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance. Since the issuance of the new revenue standard, additional guidance was issued to clarify certain aspects of the new revenue standard, including principal versus agent considerations, identifying performance obligations, and other narrow scope improvements. The new revenue standard, and related amendments, became effective for us on January 1, 2018.  The standard may be adopted using a full retrospective application or a simplified transition method that allows entities to record a cumulative effect adjustment in retained earnings at the date of initial application.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;We adopted this standard and related amendments on January 1, 2018 using the modified retrospective transition approach. The adoption of the new revenue guidance resulted in expanded disclosures, but otherwise did not have a material impact on our financial statements.  See Note 20.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:center;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;ASU 2016-01, Financial Instruments: Recognition and Measurement&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; In January 2016, a new accounting standard was issued relating to the recognition and measurement of financial instruments. The new guidance requires certain investments in equity securities to be measured at fair value with changes in fair value recognized in net income, and modifies the impairment assessment of certain equity securities.  The new standard was effective for us on January 1, 2018. The standard required modified retrospective application, with the exception of certain aspects of the standard that required prospective &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;application.  We adopted this standard on January 1, 2018, using primarily a retrospective approach.  Due to regulatory accounting treatment, the adoption of this standard did not have a material impact on our financial statements.  See Notes 13 and 19 for disclosures relating to our investments in debt and equity securities.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;ASU 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;In August 2016, a new accounting standard was issued that clarifies how entities should present certain specific cash flow activities on the statement of cash flows. The guidance is intended to eliminate diversity in practice in how entities classify these specific activities between cash flows from operating activities, investing activities and financing activities. The specific activities addressed include debt prepayments and extinguishment costs, proceeds from the settlement of insurance claims, proceeds from corporate-owned life insurance policies, and other activities. The standard also addresses how entities should apply the predominance principle when a transaction includes separately identifiable cash flows.  The new standard was effective for us, and was adopted on January 1, 2018, using a retrospective transition method.  The adoption of this guidance did not have a significant impact on our financial statements, as either our statement of cash flow presentation is consistent with the new prescribed guidance or we do not have significant activities relating to the specific transactions that are addressed by the new standard.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;ASU 2016-18, Statement of Cash Flows: Restricted Cash&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;In November 2016, a new accounting standard was issued that clarifies how restricted cash and restricted cash equivalents should be presented on the statement of cash flows. The new guidance requires entities to include restricted cash and restricted cash equivalents as a component of the beginning and ending cash and cash equivalent balances on the statement of cash flows. The new standard is effective for us, and was adopted on January 1, 2018, using a retrospective transition method. The adoption of this guidance did not impact our financial statements, as our holdings and activities designated as restricted cash and restricted cash equivalents at transition and in prior periods are insignificant.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;ASU 2017-01, Business Combinations:  Clarifying the Definition of a Business&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;In January 2017, a new accounting standard was issued that clarifies the definition of a business. This standard is intended to assist entities with evaluating whether a transaction should be accounted for as an acquisition (or disposal) of assets or a business. &#160;The definition of a business affects many areas of accounting, including acquisitions, disposals, goodwill, and consolidation.  The new standard was effective for us and was adopted on January 1, 2018 using a prospective transition approach. This standard did not have an impact on our financial statements on the date of adoption.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;ASU 2017-05, Other Income: Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;In February 2017, a new accounting standard was issued that intended to clarify the scope of accounting guidance pertaining to gains and losses from the derecognition of nonfinancial assets, and to add guidance for partial sales of nonfinancial assets.  The new standard was effective for us, and was adopted on January 1, 2018, using a modified retrospective transition approach.  This standard did not have a significant impact on our financial statements on the date of adoption.

The presentation changes  require net benefit costs to be disaggregated on the income statement by the various components that comprise these costs. Specifically, only the service cost component is eligible for presentation as an operating income item, and all other cost components are now presented as non-operating items. This presentation change was applied retrospectively. Furthermore, the new standard allows only the service cost component to be eligible for capitalization. The change in capitalization requirements was applied prospectively. The new guidance was effective for us on January 1, 2018.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;We adopted this new accounting standard on January 1, 2018. As a result of adopting this standard we have presented the non-service cost components of net benefits costs in other income instead of operating income.  Prior year non-service cost components have also been reclassified to conform to this new presentation.  We elected to apply the practical expedient guidance.  As such, prior period costs have been estimated based on amounts previously disclosed in our pension and other postretirement benefit plan notes.  The changes impacting capitalization have been adopted prospectively.  As such, upon adoption, we are no longer capitalizing a portion of the non-service cost components of net benefit costs.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; In 2018 the non-service credit components are a reduction to total benefit costs.  Excluding non-service credits from eligible capitalization costs resulted in the capitalization of an additional &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$15 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; of net benefit costs, with a corresponding increase to pretax income for the year.

Amounts eligible for reclassification must relate to the effects from the Tax Act remaining in accumulated other comprehensive income. The new guidance also requires expanded disclosures. This guidance is effective for us on January 1, 2019 with early application permitted. The guidance should be applied either in the period of adoption or retrospectively to each period in which the effect of the Tax Act was recognized.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;We early adopted this guidance in the quarter ended March 31, 2018, and we have elected to reclassify the income tax effects of the Tax Act related to other comprehensive income to retained earnings.  As of December 31, 2018, on a consolidated basis our accumulated other comprehensive income decreased &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$9 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;, and APS's accumulated other comprehensive income decreased &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$5 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;, as a result of adopting this guidance.  Amounts were reclassified from accumulated other comprehensive income to retained earnings, and related to tax rate changes.  The adoption of this guidance did not impact our income from continuing operations. See Note 4 for additional discussion of the Tax Act.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:174%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-style:italic;font-weight:bold;"&gt;Standards Adopted in 2019 &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;ASU 2016-02, Leases&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; In February 2016, a new lease accounting standard was issued. This new standard supersedes the existing lease accounting model, and modifies both lessee and lessor accounting. The new standard requires a lessee to reflect most operating lease arrangements on the balance sheet by recording a right-of-use asset and a lease liability that is initially measured at the present value of lease payments. Among other changes, the new standard also modifies the definition of a lease, and requires expanded lease disclosures. Since the issuance of the new lease standard, additional lease related guidance has been issued relating to land easements and how entities may elect to account for these arrangements at transition, among other items.  The new lease standard and related amendments were effective for us on January 1, 2019, with early application permitted. The standard must be adopted using a modified retrospective approach with a cumulative-effect adjustment to the opening balance of retained earnings determined at either the date of adoption, or the earliest period presented in the financial statements.  The standard includes various optional practical expedients provided to facilitate transition.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;We adopted this standard, and related amendments, on January 1, 2019.  We elected the transition method that allows us to apply the guidance on the date of adoption, January 1, 2019, and will not retrospectively adjust prior periods.  We also elected certain transition practical expedients that allow us to not reassess (a) whether any expired or existing contracts are or contain leases, (b) the lease classification for any expired or existing leases and (c) initial direct costs for any existing leases.  These practical expedients apply to leases that commenced prior to January 1, 2019.  Furthermore, we elected the practical expedient transition provisions relating to the treatment of existing land easements.  &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;On January 1, 2019 the adoption of this new accounting standard resulted in the recognition on our Consolidated Balance Sheets of approximately &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$194 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; of right-of-use lease assets and &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$119 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; of lease liabilities relating to our operating lease arrangements. The right-of-use lease assets include &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$85 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; of prepaid lease costs that have been reclassified from other deferred debits, and &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$10 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; of deferred lease costs that have been reclassified from other current liabilities. In addition to these balance sheet impacts the adoption of the guidance will also result in expanded lease related disclosures in our 2019 financial statements. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;ASU 2017-12, Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;In August 2017, a new accounting standard was issued that modifies hedge accounting guidance with the intent of simplifying the application of hedge accounting. The new standard became effective for us on January 1, 2019, with early application permitted.  At transition, the guidance requires the changes to be applied to hedging relationships existing on the date of adoption, with the effect of adoption reflected as of the beginning of the fiscal year of adoption using a cumulative effect adjustment approach.  The presentation and disclosure changes may be applied prospectively. We adopted this standard on January 1, 2019 and because we are not currently applying hedge accounting, the adoption of the standard did not impact our financial statements.  &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-style:italic;font-weight:bold;"&gt;Standards Pending Adoption&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;ASU 2016-13, Financial Instruments:  Measurement of Credit Losses&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;In June 2016, a new accounting standard was issued that amends the measurement of credit losses on certain financial instruments.

To determine which implementation costs should be capitalized, the new guidance aligns the accounting with existing guidance pertaining to internal-use software. As a result of this new standard, certain cloud computing service arrangement implementation costs will now be subject to capitalization and amortized on a straight-line basis over the cloud computing service arrangement term. The new standard is effective for us on January 1, 2020, with early application permitted, and may be applied using either a retrospective or prospective transition approach.

This standard provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance. Since the issuance of the new revenue standard, additional guidance was issued to clarify certain aspects of the new revenue standard, including principal versus agent considerations, identifying performance obligations, and other narrow scope improvements. The new revenue standard, and related amendments, became effective for us on January 1, 2018.

The new guidance requires certain investments in equity securities to be measured at fair value with changes in fair value recognized in net income, and modifies the impairment assessment of certain equity securities.

The guidance is intended to eliminate diversity in practice in how entities classify these specific activities between cash flows from operating activities, investing activities and financing activities. The specific activities addressed include debt prepayments and extinguishment costs, proceeds from the settlement of insurance claims, proceeds from corporate-owned life insurance policies, and other activities. The standard also addresses how entities should apply the predominance principle when a transaction includes separately identifiable cash flows.  The new standard was effective for us, and was adopted on January 1, 2018, using a retrospective transition method.  The adoption of this guidance did not have a significant impact on our financial statements, as either our statement of cash flow presentation is consistent with the new prescribed guidance or we do not have significant activities relating to the specific transactions that are addressed by the new standard.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;ASU 2016-18, Statement of Cash Flows: Restricted Cash&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;In November 2016, a new accounting standard was issued that clarifies how restricted cash and restricted cash equivalents should be presented on the statement of cash flows. The new guidance requires entities to include restricted cash and restricted cash equivalents as a component of the beginning and ending cash and cash equivalent balances on the statement of cash flows. The new standard is effective for us, and was adopted on January 1, 2018, using a retrospective transition method. The adoption of this guidance did not impact our financial statements, as our holdings and activities designated as restricted cash and restricted cash equivalents at transition and in prior periods are insignificant.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;ASU 2017-01, Business Combinations:  Clarifying the Definition of a Business&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;In January 2017, a new accounting standard was issued that clarifies the definition of a business. This standard is intended to assist entities with evaluating whether a transaction should be accounted for as an acquisition (or disposal) of assets or a business. &#160;The definition of a business affects many areas of accounting, including acquisitions, disposals, goodwill, and consolidation.  The new standard was effective for us and was adopted on January 1, 2018 using a prospective transition approach. This standard did not have an impact on our financial statements on the date of adoption.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;ASU 2017-05, Other Income: Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;In February 2017, a new accounting standard was issued that intended to clarify the scope of accounting guidance pertaining to gains and losses from the derecognition of nonfinancial assets, and to add guidance for partial sales of nonfinancial assets.  The new standard was effective for us, and was adopted on January 1, 2018, using a modified retrospective transition approach.  This standard did not have a significant impact on our financial statements on the date of adoption.  On July 3, 2018, 4CA sold its &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;7%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; interest in Four Corners.

The presentation changes  require net benefit costs to be disaggregated on the income statement by the various components that comprise these costs. Specifically, only the service cost component is eligible for presentation as an operating income item, and all other cost components are now presented as non-operating items. This presentation change was applied retrospectively. Furthermore, the new standard allows only the service cost component to be eligible for capitalization. The change in capitalization requirements was applied prospectively. The new guidance was effective for us on January 1, 2018.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;We adopted this new accounting standard on January 1, 2018. As a result of adopting this standard we have presented the non-service cost components of net benefits costs in other income instead of operating income.  Prior year non-service cost components have also been reclassified to conform to this new presentation.  We elected to apply the practical expedient guidance.  As such, prior period costs have been estimated based on amounts previously disclosed in our pension and other postretirement benefit plan notes.  The changes impacting capitalization have been adopted prospectively.  As such, upon adoption, we are no longer capitalizing a portion of the non-service cost components of net benefit costs.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; In 2018 the non-service credit components are a reduction to total benefit costs.  Excluding non-service credits from eligible capitalization costs resulted in the capitalization of an additional &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$15 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; of net benefit costs, with a corresponding increase to pretax income for the year. See Note 7 for additional information related to our pension plans and other postretirement benefits.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;ASU 2018-02, Income Statement-Reporting Comprehensive Income: Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;In February 2018, new accounting guidance was issued that allows entities an optional election to reclassify the income tax effects of the Tax Act on items within accumulated other comprehensive income to retained earnings. Amounts eligible for reclassification must relate to the effects from the Tax Act remaining in accumulated other comprehensive income. The new guidance also requires expanded disclosures. This guidance is effective for us on January 1, 2019 with early application permitted. The guidance should be applied either in the period of adoption or retrospectively to each period in which the effect of the Tax Act was recognized.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;We early adopted this guidance in the quarter ended March 31, 2018, and we have elected to reclassify the income tax effects of the Tax Act related to other comprehensive income to retained earnings.  As of December 31, 2018, on a consolidated basis our accumulated other comprehensive income decreased &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$9 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;, and APS's accumulated other comprehensive income decreased &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$5 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;, as a result of adopting this guidance.  Amounts were reclassified from accumulated other comprehensive income to retained earnings, and related to tax rate changes.  The adoption of this guidance did not impact our income from continuing operations. See Note 4 for additional discussion of the Tax Act.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:174%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-style:italic;font-weight:bold;"&gt;Standards Adopted in 2019 &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;ASU 2016-02, Leases&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; In February 2016, a new lease accounting standard was issued. This new standard supersedes the existing lease accounting model, and modifies both lessee and lessor accounting. The new standard requires a lessee to reflect most operating lease arrangements on the balance sheet by recording a right-of-use asset and a lease liability that is initially measured at the present value of lease payments. Among other changes, the new standard also modifies the definition of a lease, and requires expanded lease disclosures. Since the issuance of the new lease standard, additional lease related guidance has been issued relating to land easements and how entities may elect to account for these arrangements at transition, among other items.  The new lease standard and related amendments were effective for us on January 1, 2019, with early application permitted. The standard must be adopted using a modified retrospective approach with a cumulative-effect adjustment to the opening balance of retained earnings determined at either the date of adoption, or the earliest period presented in the financial statements.  The standard includes various optional practical expedients provided to facilitate transition.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;We adopted this standard, and related amendments, on January 1, 2019.  We elected the transition method that allows us to apply the guidance on the date of adoption, January 1, 2019, and will not retrospectively adjust prior periods.  We also elected certain transition practical expedients that allow us to not reassess (a) whether any expired or existing contracts are or contain leases, (b) the lease classification for any expired or existing leases and (c) initial direct costs for any existing leases.  These practical expedients apply to leases that commenced prior to January 1, 2019.  Furthermore, we elected the practical expedient transition provisions relating to the treatment of existing land easements.  &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;On January 1, 2019 the adoption of this new accounting standard resulted in the recognition on our Consolidated Balance Sheets of approximately &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$194 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; of right-of-use lease assets and &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$119 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; of lease liabilities relating to our operating lease arrangements. The right-of-use lease assets include &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$85 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; of prepaid lease costs that have been reclassified from other deferred debits, and &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$10 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; of deferred lease costs that have been reclassified from other current liabilities. In addition to these balance sheet impacts the adoption of the guidance will also result in expanded lease related disclosures in our 2019 financial statements. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;ASU 2017-12, Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;In August 2017, a new accounting standard was issued that modifies hedge accounting guidance with the intent of simplifying the application of hedge accounting. The new standard became effective for us on January 1, 2019, with early application permitted.  At transition, the guidance requires the changes to be applied to hedging relationships existing on the date of adoption, with the effect of adoption reflected as of the beginning of the fiscal year of adoption using a cumulative effect adjustment approach.  The presentation and disclosure changes may be applied prospectively. We adopted this standard on January 1, 2019 and because we are not currently applying hedge accounting, the adoption of the standard did not impact our financial statements.  &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-style:italic;font-weight:bold;"&gt;Standards Pending Adoption&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;ASU 2016-13, Financial Instruments:  Measurement of Credit Losses&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;In June 2016, a new accounting standard was issued that amends the measurement of credit losses on certain financial instruments.

To determine which implementation costs should be capitalized, the new guidance aligns the accounting with existing guidance pertaining to internal-use software. As a result of this new standard, certain cloud computing service arrangement implementation costs will now be subject to capitalization and amortized on a straight-line basis over the cloud computing service arrangement term. The new standard is effective for us on January 1, 2020, with early application permitted, and may be applied using either a retrospective or prospective transition approach.

This amount excluded amounts that were then collected on customer bills through adjustor mechanisms.  The application requested that some of the balances in these adjustor accounts (aggregating to approximately &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$267.6 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; as of December 31, 2015) be transferred into base rates through the ratemaking process.  This transfer would not have had an incremental effect on average customer bills.  The average annual customer bill impact of APS&#x2019;s request was an increase of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;5.74%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; (the average annual bill impact for a typical APS residential customer was &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;7.96%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;).  &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;padding-left:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;On March 27, 2017, a majority of the stakeholders in the general retail rate case, including the ACC Staff, the Residential Utility Consumer Office, limited income advocates and private rooftop solar organizations signed a settlement agreement (the "2017 Settlement Agreement") and filed it with the ACC.  The 2017 Settlement Agreement provides for a net retail base rate increase of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$94.6 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;, excluding the transfer of adjustor balances, consisting of: (1) a non-fuel, non-depreciation, base rate increase of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$87.2 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; per year; (2) a base rate decrease of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$53.6 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; attributable to reduced fuel and purchased power costs; and (3) a base rate increase of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$61.0 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; due to changes in depreciation schedules.  The average annual customer bill impact under the 2017 Settlement Agreement was calculated as an increase of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;3.28%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; (the average annual bill impact for a typical APS residential customer was calculated as &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;4.54%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;).&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;Other key provisions of the agreement include the following:&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;table cellpadding="0" cellspacing="0" style="font-family:Times New Roman;

The notice raises a single issue related to the application of certain rate schedules to new APS residential customers after May 1, 2018. Mr. Woodward filed a second notice of appeal on November 13, 2017 challenging APS&#x2019;s &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$5&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; per month automated metering infrastructure opt-out program. Mr. Woodward&#x2019;s two appeals have been consolidated, and APS requested and was granted intervention.  Mr. Woodward filed his opening brief on March 28, 2018.&#160; The ACC and APS filed responsive briefs on June 21, 2018.  The Arizona Court of Appeals issued a Memorandum Decision on December 11, 2018 affirming the ACC decisions challenged by Mr. Woodward.&#160; Mr. Woodward filed a petition for review with the Arizona Supreme Court on January 9, 2019. Review by the Arizona Supreme Court is discretionary. APS cannot predict the outcome of this consolidated appeal but does not believe it will have a material impact on our financial position, results of operations or cash flows. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;On January 3, 2018, an APS customer filed a petition with the ACC that was determined by the ACC Staff to be a complaint filed pursuant to Arizona Revised Statute &#xa7;40-246 (the &#x201c;Complaint&#x201d;) and not a request for rehearing. Arizona Revised Statute &#xa7;40-246 requires the ACC to hold a hearing regarding any complaint alleging that a public service corporation is in violation of any commission order or that the rates being charged are not just and reasonable if the complaint is signed by at least &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;twenty-five&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; customers of the public &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;service corporation.  The Complaint alleged that APS is &#x201c;in violation of commission order&#x201d; [sic].  On February 13, 2018, the complainant filed an amended Complaint alleging that the rates and charges in the 2017 Rate Case Decision are not just and reasonable.&#160; The complainant requested that the ACC hold a hearing on the amended Complaint to determine if the average bill impact on residential customers of the rates and charges approved in the 2017 Rate Case Decision is greater than 4.54% (the average annual bill impact for a typical APS residential customer estimated by APS,) and, if so, what effect the alleged greater bill impact has on APS's revenues and the overall reasonableness and justness of APS's rates and charges, in order to determine if there is sufficient evidence to warrant a full-scale rate hearing.&#160; The ACC held a hearing on this matter beginning in September 2018 and the hearing was concluded on October 1, 2018.   Post-hearing briefing was concluded on December 14, 2018.  APS expects a recommended opinion and order from the judge within the first quarter of 2019.  APS cannot predict the outcome of this matter.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;On December 24, 2018, certain ACC Commissioners filed a letter stating that because the ACC had received a substantial number of complaints that the rate increase authorized by the 2017 Rate Case Decision was much more than anticipated, they believe there is a possibility that APS is earning more than was authorized by the 2017 Rate Case Decision.&#160; Accordingly, the ACC Commissioners requested the ACC Staff to perform a rate review of APS using calendar year 2018 as a test year and file a report by May 3, 2019.&#160; The ACC Commissioners also asked the ACC Staff to evaluate APS&#x2019;s efforts to educate its customers regarding the new rates approved in the 2017 Rate Case Decision.&#160; On January 9, 2019, the ACC Commissioners voted to open a docket for this matter.&#160; APS does not believe that the rate review will have a material impact on our financial position, results of operations or cash flows.&#160; However, depending upon the results of the rate review, the ACC may take further actions, including potentially attempting to reopen the 2017 Rate Case Decision.&#160; APS cannot predict the outcome of this matter.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;Prior Rate Case Filing with the Arizona Corporation Commission&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;On June&#160;1, 2011, APS filed an application with the ACC for a net retail base rate increase of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$95.5 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;.&#160; On January&#160;6, 2012, APS and other parties to the general retail rate case entered into an agreement (the "2012 Settlement Agreement") detailing the terms upon which the parties agreed to settle the rate case.&#160; On May&#160;15, 2012, the ACC approved the 2012 Settlement Agreement without material modifications.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;Cost Recovery Mechanisms &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;APS has received regulatory decisions that allow for more timely recovery of certain costs outside of a general retail rate case through the following recovery mechanisms.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-style:italic;font-weight:bold;"&gt;Renewable Energy Standard&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;.&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160; In 2006, the ACC approved the RES.&#160; 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.&#160; 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.&#160; Each year APS is required to file a five-year implementation plan with the ACC and seek approval for funding the upcoming year&#x2019;s RES budget.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;In 2013, the ACC conducted a hearing to consider APS&#x2019;s proposal to establish compliance with distributed energy requirements by tracking and recording distributed energy, rather than acquiring and retiring renewable energy credits. On February&#160;6, 2014, the ACC established a proceeding to modify the renewable energy rules&#160;to establish a process for compliance with the renewable energy requirement that is not based solely on the use of renewable energy credits. On September 9, 2014, the ACC authorized a rulemaking process to modify the RES rules. The proposed changes would permit the ACC to find that utilities have &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;complied with the distributed energy requirement in light of all available information. The ACC adopted these changes on December 18, 2014.&#160; The revised rules went into effect on April 21, 2015.&#160;&#160;&#160;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11pt;"&gt;&lt;span style="font-family:inherit;font-size:11pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;In December 2014, the ACC voted that it had no objection to APS implementing an APS-owned rooftop solar research and development program aimed at learning how to efficiently enable the integration of rooftop solar and battery storage with the grid.&#160; The first stage of the program, called the "Solar Partner Program," placed &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;8&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; MW of residential rooftop solar on strategically selected distribution feeders in an effort to maximize potential system benefits, as well as made systems available to limited-income customers who could not easily install solar through transactions with third parties.&#160;The second stage of the program, which included an additional &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;2&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; MW of rooftop solar and energy storage, placed &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;two&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; energy storage systems sized at &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;2&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; MW on &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;two&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; different high solar penetration feeders to test various grid-related operation improvements and system interoperability, and was in operation by the end of 2016. &#160;The costs for this program have been included in APS's rate base as part of the 2017 Rate Case Decision.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;On July 1, 2016, APS filed its 2017 RES Implementation Plan and proposed a budget of approximately &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$150 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;.  APS&#x2019;s budget request included additional funding to process the high volume of residential rooftop solar interconnection requests and also requested a permanent waiver of the residential distributed energy requirement for 2017 contained in the RES rules.  On April 7, 2017, APS filed an amended 2017 RES Implementation Plan and updated budget request which included the revenue neutral transfer of specific revenue requirements into base rates in accordance with the 2017 Settlement Agreement.&#160; On August 15, 2017, the ACC approved the 2017 RES Implementation Plan.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;On June 30, 2017, APS filed its 2018 RES Implementation Plan and proposed a budget of approximately &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$90 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;.&#160; APS&#x2019;s budget request supports existing approved projects and commitments and includes the anticipated transfer of specific revenue requirements into base rates in accordance with the 2017 Settlement Agreement and also requests a permanent waiver of the residential distributed energy requirement for 2018 contained in the RES rules.  APS's 2018 RES budget request is lower than the 2017 RES budget due in part to a certain portion of the RES being collected by APS in base rates rather than through the RES adjustor. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;On November 20, 2017, APS filed an updated 2018 RES budget to include budget adjustments for APS Solar Communities (formerly known as AZ Sun II), which was approved as part of the 2017 Rate Case Decision.  APS Solar Communities is a &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;3&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;-year program authorizing APS to spend &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$10&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; million to &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$15 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; in capital costs each year to install utility-owned DG systems for low to moderate income residential homes, buildings of non-profit entities, Title I schools and rural government facilities.  The 2017 Rate Case Decision provided that all operations and maintenance expenses, property taxes, marketing and advertising expenses, and the capital carrying costs for this program will be recovered through the RES.  On June 12, 2018, the ACC approved the 2018 RES Implementation Plan.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;On June 29, 2018, APS filed its 2019 RES Implementation Plan and proposed a budget of approximately &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$89.9 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;.&#160; APS&#x2019;s budget request supports existing approved projects and commitments and requests a permanent waiver of the residential distributed energy requirement for 2019 contained in the RES rules.  The ACC has not yet ruled on the 2019 RES Implementation Plan.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11pt;color:#009644;"/&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;In September 2016, the ACC initiated a proceeding which will examine the possible modernization and expansion of the RES.  On January 30, 2018, ACC Commissioner Tobin proposed a plan in this proceeding which would broaden the RES to include a series of energy policies tied to clean energy sources (the "Energy Modernization Plan").  The Energy Modernization Plan includes replacing the current RES standard with a new standard called the Clean Resource Energy Standard and Tariff ("CREST"), which incorporates the &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;proposals in the Energy Modernization Plan.&#160; A set of draft CREST rules for the ACC&#x2019;s consideration was issued by Commissioner Tobin&#x2019;s office on July 5, 2018.  See "Energy Modernization Plan" below for more information on CREST.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-style:italic;font-weight:bold;"&gt;Demand Side Management Adjustor Charge&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;.  &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;The ACC EES requires APS to submit a Demand Side Management Implementation Plan ("DSM Plan") annually for review by and approval of the ACC.  On March 20, 2015, APS filed an application with the ACC requesting a budget of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$68.9 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; for 2015 and minor modifications to its DSM portfolio going forward, including for the first time &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;three&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; resource savings projects which reflect energy savings on APS's system.  The ACC approved APS&#x2019;s 2015 DSM budget on November 25, 2015.  In its decision, the ACC also ruled that verified energy savings from APS's resource savings projects could be counted toward compliance with the EES; however, the ACC ruled that APS was not allowed to count savings from systems savings projects toward determination of the achievement of performance incentives, nor may APS include savings from conservation voltage reduction in the calculation of its LFCR mechanism.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;On June 1, 2016, APS filed its 2017 DSM Plan, in which APS proposed programs and measures that specifically focus on reducing peak demand, shifting load to off-peak periods and educating customers about strategies to manage their energy and demand.&#160; The requested budget in the 2017 DSM Plan was &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$62.6 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;.  On January 27, 2017, APS filed an updated and modified 2017 DSM Plan that incorporated the proposed Residential Demand Response, Energy Storage and Load Management Program and requested that the budget be increased to &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$66.6 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;.  On August 15, 2017, the ACC approved the amended 2017 DSM Plan.  &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;On September 1, 2017, APS filed its 2018 DSM Plan, which proposes modifications to the demand side management portfolio to better meet system and customer needs by focusing on peak demand reductions, storage, load shifting and demand response programs in addition to traditional energy savings measures. The 2018 DSM Plan seeks a reduced requested budget of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$52.6 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; and requests a waiver of the EES for 2018.&#160;&#160; On November 14, 2017, APS filed an amended 2018 DSM Plan, which revised the allocations between budget items to address customer participation levels, but kept the overall budget at &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$52.6 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;.

That rate was &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$0.001658&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; per kWh and consisted of a forward component of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$0.000536&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; per kWh and a historical component of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$0.001122&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; per kWh.  The 2019 PSA rate is a &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$0.002897&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; per kWh decrease compared to 2018.  These rates went into effect as filed on February 1, 2019.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-style:italic;font-weight:bold;"&gt;Transmission Rates, Transmission Cost Adjustor and Other Transmission Matters&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;.&#160;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;  In July&#160;2008, FERC approved an Open Access Transmission Tariff for APS to move from fixed rates to a formula rate-setting methodology in order to more accurately reflect and recover the costs that APS incurs in providing transmission services.&#160; A large portion of the rate represents charges for transmission services to serve APS's retail customers ("Retail Transmission Charges").&#160; In order to recover the Retail Transmission Charges, APS was previously required to file an application with, and obtain approval from, the ACC to reflect changes in Retail Transmission Charges through the TCA.&#160; Under the terms of the 2012 Settlement Agreement, however, an adjustment to rates to recover the Retail Transmission Charges will be made annually each June&#160;1 and will go into effect automatically unless suspended by the ACC.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;The formula rate is updated each year effective June&#160;1 on the basis of APS's actual cost of service, as disclosed in APS's FERC Form&#160;1 report for the previous fiscal year.&#160; Items to be updated include actual capital expenditures made as compared with previous projections, transmission revenue credits and other items.&#160; The resolution of proposed adjustments can result in significant volatility in the revenues to be collected.&#160; APS reviews the proposed formula rate filing amounts with the ACC Staff.&#160; 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.&#160; Settlement or litigated resolution of disputed issues could require an extended period of time and could have a significant effect on the Retail Transmission Charges because any adjustment, though applied prospectively, may be calculated to account for previously over- or under-collected amounts.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:12pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"/&gt;&lt;span style="font-family:inherit;font-size:12pt;"&gt;Effective June&#160;1, 2017, APS's annual wholesale transmission rates for all users of its transmission system increased by approximately &lt;/span&gt;&lt;span style="font-family:inherit;font-size:12pt;"&gt;&lt;span&gt;$35.1 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:12pt;"&gt; for the twelve-month period beginning June 1, 2017 in accordance with the FERC-approved formula.&#160; An adjustment to APS&#x2019;s retail rates to recover FERC approved transmission charges went into effect automatically on June&#160;1, 2017.  Effective June&#160;1, 2018, APS's annual wholesale transmission rates for all users of its transmission system decreased by approximately &lt;/span&gt;&lt;span style="font-family:inherit;font-size:12pt;"&gt;&lt;span&gt;$22.7 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:12pt;"&gt; for the twelve-month period beginning June 1, 2018 in accordance with the FERC-approved formula.&#160; An adjustment to APS&#x2019;s retail rates to recover FERC approved transmission charges went into effect automatically on June&#160;1, 2018.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:12pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"/&gt;&lt;span style="font-family:inherit;font-size:12pt;"&gt;On January 31, 2017, APS made a filing with FERC to reduce the Post-Employment Benefits Other than Pension expense reflected in its FERC transmission formula rate calculation to recognize certain savings resulting from plan design changes to the other postretirement benefit plans.&#160; A transmission customer intervened and protested certain aspects of APS&#x2019;s filing.&#160; FERC initiated a proceeding under Section 206 of the Federal Power Act to evaluate the justness and reasonableness of the revised formula rate filing APS proposed.&#160; APS entered into a settlement agreement with the intervening transmission customer, which was filed with FERC for approval on September 26, 2017.  FERC approved the settlement agreement without modification or condition on December 21, 2017.  &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:12pt;"&gt;&lt;span style="font-family:inherit;font-size:12pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:12pt;"&gt;&lt;span style="font-family:inherit;font-size:12pt;"&gt;On March 7, 2018, APS made a filing to make modifications to its annual transmission formula to provide transmission customers the benefit of the reduced federal corporate income tax rate resulting from the Tax Act beginning in its 2018 annual transmission formula rate update filing. These modifications were approved by FERC on May 22, 2018 and reduced APS&#x2019;s transmission rates compared to the rate that would have gone into effect absent these changes.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:12pt;"&gt;&lt;span style="font-family:inherit;font-size:12pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-style:italic;font-weight:bold;"&gt;Lost Fixed Cost Recovery Mechanism&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;.  &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;The LFCR mechanism permits APS to recover on an after-the-fact basis a portion of its fixed costs that would otherwise have been collected by APS in the kWh sales lost due to APS energy efficiency programs and to DG such as rooftop solar arrays.&#160; The fixed costs recoverable by the LFCR mechanism were first established in the 2012 Settlement Agreement and amount to approximately &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;3.1 cent&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;s per residential kWh lost and &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;2.3 cents&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; per non-residential kWh lost.&#160; These amounts were revised in the 2017 Settlement Agreement to &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;2.5 cents&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; for both lost residential and non-residential kWh.  The LFCR adjustment has a year-over-year cap of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;1%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; of retail revenues.&#160; Any amounts left unrecovered in a particular year because of this cap can be carried over for recovery in a future year.&#160; The kWh&#x2019;s lost from energy efficiency are based on a third-party evaluation of APS&#x2019;s energy efficiency programs.&#160; DG sales losses are determined from the metered output from the DG units.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;APS filed its 2016 annual LFCR adjustment on January 15, 2016, requesting an LFCR adjustment of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$46.4 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; (a &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$7.9 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; annual increase).  The ACC approved the 2016 annual LFCR effective beginning in May 2016.  APS filed its 2017 LFCR adjustment on January 13, 2017 requesting an LFCR adjustment of &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$63.7 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; (a &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$17.3 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; per year increase over 2016 levels).  On April 5, 2017, the ACC approved the 2017 annual LFCR adjustment as filed, effective with the first billing cycle of April 2017.  On February 15, 2018, APS filed its 2018 annual LFCR Adjustment, requesting that effective May 1, 2018, the LFCR be adjusted to &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$60.7 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; (a &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$3 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; per year decrease from 2017 levels).  On February 6, 2019, the ACC approved the 2018 annual LFCR adjustment to become effective March 1, 2019.  On February 15, 2019, APS filed its 2019 annual LFCR adjustment, requesting that effective May 1, 2019, the annual LFCR recovery amount be reduced to &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$36.2 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; (a &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$24.5 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; decrease from previous levels).  Because the LFCR mechanism has a balancing account that trues up any under or over recoveries, the delay in implementation does not have an adverse effect on APS. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11pt;"&gt;&lt;span style="font-family:inherit;font-size:11pt;color:#ff0000;"&gt;&#160;&#160;&#160;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11pt;"/&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-style:italic;font-weight:bold;"&gt;Tax Expense Adjustor Mechanism and FERC Tax Filing.&#160; &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;As part of the 2017 Settlement Agreement, the parties agreed to a rate adjustment mechanism to address potential federal income tax reform and enable the pass-through of certain income tax effects to customers. On December 22, 2017, the Tax Act was enacted.&#160; This legislation made significant changes to the federal income tax laws including a reduction in the corporate tax rate from 35% to 21% effective January 1, 2018.  &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;On January 8, 2018, APS filed an application with the ACC requesting that the TEAM be implemented in two steps.&#160; The first addresses the change in the marginal federal tax rate from &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;35%&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; to &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;21%&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; resulting from the Tax Act and, if approved, would reduce rates by &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$119.1 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; annually through an equal cents per kWh credit.&#160; APS asked that this decrease become effective February 1, 2018.  On February 22, 2018, the ACC approved the reduction of rates by &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$119.1 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; for the remainder of 2018 through an equal cents per kWh credit applied to all but a small subset of customers who are taking service under specially-approved tariffs. The rate reduction was effective &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11pt;"&gt;for the first billing cycle in &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;March 2018. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;The impact of the TEAM, over time, is expected to be earnings neutral. However, on a quarterly basis, there is a difference between the timing and amount of the income tax benefit and the reduction in revenues refunded through the TEAM related to the lower federal income tax rate. The amount of the benefit of the lower federal income tax rate is based on quarterly pre-tax results, while the reduction in revenues from the prior year due to lower customer rates through the TEAM is based on a per kWh sales credit which follows our seasonal kWh sales pattern and is not impacted by earnings of the Company.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;On August 13, 2018, APS filed a second request with the ACC to return an additional &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$86.5 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; in tax savings to customers. This second request addresses amortization of non-depreciation related excess deferred taxes previously collected from customers. The ACC has not yet approved this request.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;Additionally, as part of this second request, APS informed the ACC of its intent to file a third future request to address the amortization of depreciation related excess deferred taxes, as the Company is currently in the process of seeking IRS guidance regarding the amortization method and period applicable to these depreciation related excess deferred taxes.  &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;The TEAM expressly applies to APS's retail rates with the exception of a small subset of customers taking service under specially-approved tariffs noted above.  As discussed under "Transmission Rates, Transmission Cost Adjustor and Other Transmission Matters" above, FERC issued an order on May 22, 2018 authorizing APS to provide for the cost reductions resulting from the income tax changes in its wholesale transmission rates.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;Net Metering&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;In 2015, the ACC voted to conduct a generic evidentiary hearing on the value and cost of DG to gather information that will inform the ACC on net metering issues and cost of service studies in upcoming utility rate cases.&#160; A hearing was held in April 2016.  On October 7, 2016, the Administrative Law Judge issued a recommendation in the docket concerning the value and cost of DG solar installations.  On December 20, 2016, the ACC completed its open meeting to consider the recommended opinion and order by the Administrative Law Judge.  After making several amendments, the ACC approved the recommended decision by a 4-1 vote.  As a result of the ACC&#x2019;s action, effective with APS&#x2019;s 2017 Rate Case Decision, the net metering tariff that governs payments for energy exported to the grid from residential rooftop solar systems was replaced by a more formula-driven approach that utilizes inputs from historical wholesale solar power until an avoided cost methodology &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11pt;"&gt;is developed by the ACC&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;As amended, the decision provides that payments by utilities for energy exported to the grid from DG solar facilities will be determined using a RCP methodology, a method that is based on the &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11pt;"&gt;most recent five-year rolling average &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;price that APS pays for utility-scale solar projects, while a forecasted avoided cost methodology is being developed.&#160; The price established by this RCP method will be updated annually (between general retail rate cases) but will not be decreased by more than &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;10%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; per year. Once the avoided cost methodology is developed, the ACC will determine in APS's subsequent rate cases which method (or a combination of methods) is appropriate to determine the actual price to be paid by APS for exported distributed energy.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;In addition, the ACC made the following determinations:&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;table cellpadding="0" cellspacing="0" style="font-family:Times New Roman; font-size:10pt;"&gt;&lt;tr&gt;&lt;td style="width:48px;"/&gt;&lt;td/&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td style="vertical-align:top"&gt;&lt;div style="line-height:120%;font-size:11.5pt;padding-left:24px;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#x2022;&lt;/span&gt;&lt;/div&gt;&lt;/td&gt;&lt;td style="vertical-align:top;"&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;Customers who have interconnected a DG system or submitted an application for interconnection for DG systems prior to September 1, 2017, the date new rates were effective based on APS's 2017 Rate Case Decision, will be grandfathered for a period of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;20&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; years from the date the customer&#x2019;s interconnection application was accepted by the utility;&lt;/span&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;div style="line-height:120%;text-align:left;padding-left:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;table cellpadding="0" cellspacing="0" style="font-family:Times New Roman; font-size:10pt;"&gt;&lt;tr&gt;&lt;td style="width:48px;"/&gt;&lt;td/&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td style="vertical-align:top"&gt;&lt;div style="line-height:120%;font-size:11.5pt;padding-left:24px;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#x2022;&lt;/span&gt;&lt;/div&gt;&lt;/td&gt;&lt;td style="vertical-align:top;"&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;Customers with DG solar systems are to be considered a separate class of customers for ratemaking purposes; and&lt;/span&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;div style="line-height:120%;text-align:left;padding-left:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;table cellpadding="0" cellspacing="0" style="font-family:Times New Roman; font-size:10pt;"&gt;&lt;tr&gt;&lt;td style="width:48px;"/&gt;&lt;td/&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td style="vertical-align:top"&gt;&lt;div style="line-height:120%;font-size:11.5pt;padding-left:24px;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#x2022;&lt;/span&gt;&lt;/div&gt;&lt;/td&gt;&lt;td style="vertical-align:top;"&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;Once an export price is set for APS, no netting or banking of retail credits will be available for new DG customers, and the then-applicable export price will be guaranteed for new customers for a period of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;10&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; years. &lt;/span&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;This decision of the ACC addresses policy determinations only.  The decision states that its principles will be applied in future general retail rate cases, and the policy determinations themselves may be subject to future change, as are all ACC policies.  A first-year export energy price of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;12.9 cents&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; per kWh is included in the 2017 Settlement Agreement and became effective on September 1, 2017. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&#160;&#160;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;In accordance with the 2017 Rate Case Decision, APS filed its request for a second-year export energy price of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;11.6 cents&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; per kWh on May 1, 2018.&#160; This price reflects the 10% annual reduction discussed above.  The new tariff became effective on October 1, 2018.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;On January 23, 2017, TASC sought rehearing of the ACC's decision regarding the value and cost of DG. TASC asserted that the ACC improperly ignored the Administrative Procedure Act, failed to give adequate notice regarding the scope of the proceedings, and relied on information that was not submitted as evidence, among other alleged defects. TASC filed a Notice of Appeal in the Arizona Court of Appeals and filed a Complaint and Statutory Appeal in the Maricopa County Superior Court on March 10, 2017.  As part of the &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;2017 Settlement Agreement described above, TASC agreed to withdraw these appeals when the ACC decision implementing the 2017 Settlement Agreement is no longer subject to appellate review.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;Subpoena from Arizona Corporation Commissioner Robert Burns&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;On August 25, 2016, Commissioner Burns, individually and not by action of the ACC as a whole, served subpoenas in APS&#x2019;s then current retail rate proceeding on APS and Pinnacle West for the production of records and information relating to a range of expenditures from 2011 through 2016. The subpoenas requested information concerning marketing and advertising expenditures, charitable donations, lobbying expenses, contributions to 501(c)(3) and (c)(4) nonprofits and political contributions.  The return date for the production of information was set as September 15, 2016. The subpoenas also sought testimony from Company personnel having knowledge of the material, including the Chief Executive Officer. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;On September 9, 2016, APS filed with the ACC a motion to quash the subpoenas or, alternatively to stay APS's obligations to comply with the subpoenas and decline to decide APS's motion pending court proceedings. Contemporaneously with the filing of this motion, APS and Pinnacle West filed a complaint for special action and declaratory judgment in the Superior Court of Arizona for Maricopa County, seeking a declaratory judgment that Commissioner Burns&#x2019; subpoenas are contrary to law.  On September 15, 2016, APS produced all non-confidential and responsive documents and offered to produce any remaining responsive documents that are confidential after an appropriate confidentiality agreement is signed.  &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;On February 7, 2017, Commissioner Burns opened a new ACC docket and indicated that its purpose is to study and rectify problems with transparency and disclosure regarding financial contributions from regulated monopolies or other stakeholders who may appear before the ACC that may directly or indirectly benefit an ACC Commissioner, a candidate for ACC Commissioner, or key ACC Staff.&#160; As part of this docket, Commissioner Burns set March 24, 2017 as a deadline for the production of all information previously requested through the subpoenas. Neither APS nor Pinnacle West produced the information requested and instead objected to the subpoena.  On March 10, 2017, Commissioner Burns filed suit against APS and Pinnacle West in the Superior Court of Arizona for Maricopa County in an effort to enforce his subpoenas.  On March 30, 2017, APS filed a motion to dismiss Commissioner Burns' suit against APS and Pinnacle West.   In response to the motion to dismiss, the court stayed the suit and ordered Commissioner Burns to file a motion to compel the production of the information sought by the subpoenas with the ACC.  On June 20, 2017, the ACC denied the motion to compel.   &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;On August 4, 2017, Commissioner Burns amended his complaint to add all of the ACC Commissioners and the ACC itself as defendants.  All defendants moved to dismiss the amended complaint.  On February 15, 2018, the Superior Court dismissed Commissioner Burns&#x2019; amended complaint. On March 6, 2018, Commissioner Burns filed an objection to the proposed final order from the Superior Court and a motion to further amend his complaint.  The Superior Court permitted Commissioner Burns to amend his complaint to add a claim regarding his attempted investigation into whether his fellow commissioners should have been disqualified from voting on APS&#x2019;s 2017 rate case. Commissioner Burns filed his second amended complaint, and all defendants filed responses opposing the second amended complaint and requested that it be dismissed.  Oral argument occurred in November 2018 regarding the motion to dismiss.  On December 18, 2018, the trial court granted the defendants&#x2019; motions to dismiss and entered final judgment on January 18, 2019.  On February 13, 2019, Commissioner Burns filed a notice of appeal.  APS and Pinnacle West cannot predict the outcome of this matter. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:13px;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;Renewable Energy Ballot Initiative&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:13px;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;On February 20, 2018, a renewable energy advocacy organization filed with the Arizona Secretary of State a ballot initiative for an Arizona constitutional amendment requiring Arizona public service corporations to provide at least &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;50%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; of their annual retail sales of electricity from renewable sources by 2030.  For purposes of the proposed amendment, eligible renewable sources would not include nuclear generating facilities.  The initiative was placed on the November 2018 Arizona elections ballot.  On November 6, 2018, the initiative failed to receive adequate voter support and was defeated.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;Energy Modernization Plan&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;On January 30, 2018, ACC Commissioner Tobin proposed the Energy Modernization Plan, which consists of a series of energy policies tied to clean energy sources such as energy storage, biomass, energy efficiency, electric vehicles, and expanded energy planning through the IRP process. The Energy Modernization Plan includes replacing the current RES standard with a new standard called the CREST, which incorporates the proposals in the Energy Modernization Plan.  On February 22, 2018, the ACC Staff filed a Notice of Inquiry to further examine the matter. As a part of this proposal, the ACC voted in March 2018 to direct utilities to develop a comprehensive biomass generation plan to be included in each utility&#x2019;s RES Implementation Plan. On July 5, 2018, Commissioner Tobin&#x2019;s office issued a set of draft CREST rules for the ACC&#x2019;s consideration.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&#160;&#160;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;In August 2018, the ACC directed ACC Staff to open a new rulemaking docket which will address a wide range of energy issues, including the Energy Modernization Plan proposals.&#160; The rulemaking will consider possible modifications to existing ACC rules, such as the Renewable Energy Standard, Electric and Gas Energy Efficiency Standards, Net Metering, Resource Planning, and the Biennial Transmission Assessment, as well as the development of new rules regarding forest bioenergy, electric vehicles, interconnection of distributed generation, baseload security, blockchain technology and other technological developments, retail competition, and other energy-related topics.&#160; Workshops on these energy issues are scheduled to be held throughout 2019.  APS cannot predict the outcome of this matter.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;Integrated Resource Planning&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;ACC rules require utilities to develop fifteen-year IRPs which describe how the utility plans to serve customer load in the plan timeframe.&#160; The ACC reviews each utility&#x2019;s IRP to determine if it meets the necessary requirements and whether it should be acknowledged.&#160; In March of 2018, the ACC reviewed the 2017 IRPs of its jurisdictional utilities and voted to not acknowledge any of the plans.&#160; APS does not believe that this lack of acknowledgment will have a material impact on our financial position, results of operations or cash flows.&#160; Based on an ACC decision, APS is required to file a Preliminary Resource Plan by April 1, 2019 and its final IRP by April 1, 2020.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;Four Corners&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"/&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-style:italic;font-weight:bold;"&gt;SCE-Related Matters&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;.   On December&#160;30, 2013, APS purchased SCE&#x2019;s &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;48%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; ownership interest in each of Units 4 and 5 of Four Corners.&#160; The 2012 Settlement Agreement includes a procedure to allow APS to request rate adjustments prior to its next general retail rate case related to APS&#x2019;s acquisition of the additional interests in Units 4 and 5 and the related closure of Units 1-3 of Four Corners.&#160; APS made its filing under this provision on December&#160;30, 2013.  On December 23, 2014, the ACC approved rate adjustments resulting in a revenue increase of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$57.1 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; on an annual basis.&#160; This included the deferral for future recovery of all non-fuel operating costs for the acquired SCE interest in Four Corners, net of the non-fuel operating costs savings &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;resulting from the closure of Units 1-3 from the date of closing of the purchase through its inclusion in rates.&#160; The 2012 Settlement Agreement also provided for deferral for future recovery of all unrecovered costs incurred in connection with the closure of Units 1-3.&#160; The deferral balance related to the acquisition of SCE&#x2019;s interest in Units 4 and 5 and the closure of Units 1-3 was &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$48 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; as of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;December&#160;31, 2018&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; and is being amortized in rates over a total of  &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;10&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; years. The ACC's rate adjustment decision was appealed and on September 26, 2017, the Court of Appeals affirmed the ACC's decision on the Four Corners rate adjustment.  &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;As part of APS&#x2019;s acquisition of SCE&#x2019;s interest in Units 4 and 5, APS and SCE agreed, via a "Transmission Termination Agreement" that, upon closing of the acquisition, the companies would terminate an existing transmission agreement ("Transmission Agreement") between the parties that provides transmission capacity on a system (the "Arizona Transmission System") for SCE to transmit its portion of the output from Four Corners to California.&#160; APS previously submitted a request to FERC related to this termination, which resulted in a FERC order denying rate recovery of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$40 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; that APS agreed to pay SCE associated with the termination.  On December 22, 2015, APS and SCE agreed to terminate the Transmission Termination Agreement and allow for the Transmission Agreement to expire according to its terms, which includes settling obligations in accordance with the terms of the Transmission Agreement.  APS established a regulatory asset of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$12 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; in 2015 in connection with the payment required under the terms of the Transmission Agreement.  On July 1, 2016, FERC issued an order denying APS&#x2019;s request to recover the regulatory asset through its FERC-jurisdictional rates.&#160; APS and SCE completed the termination of the Transmission Agreement on July 6, 2016.  APS made the required payment to SCE and wrote-off the &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$12 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; regulatory asset and charged operating revenues to reflect the effects of this order in the second quarter of 2016. &#160;On July 29, 2016, APS filed a request for rehearing with FERC.  In its order denying recovery, FERC also referred to its enforcement division a question of whether the agreement between APS and SCE relating to the settlement of obligations under the Transmission Agreement was a jurisdictional contract that should have been filed with FERC.  On October 5, 2017, FERC issued an order denying APS's request for rehearing.  FERC also upheld its prior determination that the agreement relating to the settlement was a jurisdictional contract and should have been filed with FERC.  APS cannot predict whether or if the enforcement division will take any action.  APS filed an appeal of FERC's July 1, 2016 and October 5, 2017 orders with the United States Court of Appeals for the Ninth Circuit on December 4, 2017.  That proceeding is pending, and APS cannot predict the outcome of the proceeding.  &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-style:italic;font-weight:bold;"&gt;SCR Cost Recovery&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;.  On December 29, 2017, in accordance with the 2017 Rate Case Decision, APS filed a Notice of Intent to file its SCR Adjustment to permit recovery of costs associated with the installation of SCR equipment at Four Corners Units 4 and 5.&#160; APS filed the SCR Adjustment request in April 2018.&#160; Consistent with the 2017 Rate Case Decision, the request was narrow in scope and addressed only costs associated with this specific environmental compliance equipment.&#160; The SCR Adjustment request provided that there would be a &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$67.5 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; annual revenue impact that would be applied as a percentage of base rates for all applicable customers.&#160; Also, as provided for in the 2017 Rate Case Decision, APS requested that the adjustment become effective no later than January 1, 2019.&#160; The hearing for this matter occurred in September 2018.&#160; At the hearing, APS accepted ACC Staff's recommendation of a lower annual revenue impact of approximately &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$58.5 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;.  The Administrative Law Judge issued a Recommended Opinion and Order finding that  the costs for the SCR project were prudently incurred and recommending authorization of the &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$58.5 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; annual revenue requirement related to the installation and operation of the SCRs.  Exceptions to the Recommended Opinion and Order were filed by the parties and intervenors on December 7, 2018.&#160; The ACC has not issued a decision on this matter.&#160; APS anticipates a decision later in 2019.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;Cholla&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;On September 11, 2014, APS announced that it would close Unit 2 of Cholla and cease burning coal at the other APS-owned units (Units 1 and 3) at the plant by the mid-2020s, if  EPA approves a compromise proposal offered by APS to meet required environmental and emissions standards and rules.  On April 14, 2015, the ACC approved APS's plan to retire Unit 2, without expressing any view on the future recoverability of APS's remaining investment in the Unit.  APS closed Unit 2 on October 1, 2015.  In early 2017, EPA approved a final rule incorporating APS's compromise proposal, which took effect on April 26, 2017.  &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;Previously, APS estimated Cholla Unit 2&#x2019;s end of life to be 2033.  APS has been recovering a return on and of the net book value of the unit in base rates.  Pursuant to the 2017 Settlement Agreement described above, APS will be allowed continued recovery of the net book value of the unit and the unit&#x2019;s decommissioning and other retirement-related costs (&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$89 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; as of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;December&#160;31, 2018&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;), in addition to a return on its investment.  In accordance with GAAP, in the third quarter of 2014, Unit 2&#x2019;s remaining net book value was reclassified from property, plant and equipment to a regulatory asset.  The 2017 Settlement Agreement also shortened the depreciation lives of Cholla Units 1 and 3 to 2026.  &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;font-size:11pt;"&gt;&lt;span style="font-family:inherit;font-size:11pt;font-weight:bold;"&gt;Navajo Plant&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;The co-owners of the Navajo Plant and the Navajo Nation agreed that the Navajo Plant will remain in operation until December 2019 under the existing plant lease.  The co-owners and the Navajo Nation executed a lease extension on November 29, 2017 that will allow for decommissioning activities to begin after the plant ceases operations in December 2019.  Various stakeholders including regulators, tribal representatives, the plant's coal supplier and the U.S. Department of the Interior have been meeting to determine if an alternate solution can be reached that would permit continued operation of the plant beyond 2019.  Although we cannot predict whether any alternate plans will be found that would be acceptable to all of the stakeholders and feasible to implement, we believe it is probable that the current owners of the Navajo Plant will cease operations in December 2019.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;On February 14, 2017, the ACC opened a docket titled "ACC Investigation Concerning the Future of the Navajo Generating Station" with the stated goal of engaging stakeholders and negotiating a sustainable pathway for the Navajo Plant to continue operating in some form after December 2019.  APS cannot predict the outcome of this proceeding.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;APS is currently recovering depreciation and a return on the net book value of its interest in the Navajo Plant over its previously estimated life through 2026.  APS will seek continued recovery in rates for the book value of its remaining investment in the plant (&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$88 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; as of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;December&#160;31, 2018&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;) plus a return on the net book value as well as other costs related to retirement and closure, which are still being assessed and may be material.  APS believes it will be allowed recovery of the net book value, in addition to a return on its investment.  In accordance with GAAP, in the second quarter of 2017, APS's remaining net book value of its interest in the Navajo Plant was reclassified from property, plant and equipment to a regulatory asset.  If the ACC does not allow full recovery of the remaining net book value of this interest, all or a portion of the regulatory asset will be written off and APS's net income, cash flows, and financial position will be negatively impacted.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span

This legislation made significant changes to the federal income tax laws, including a reduction in the corporate tax rate to &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11pt;"&gt;21%&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11pt;"&gt; effective January 1, 2018.

As of December 31, 2017, to reflect the&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$1.14 billion&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11pt;"&gt;reduction in its net deferred income tax liabilities caused by the rate reduction, APS has recorded a net regulatory liability of &lt;/span&gt;&lt;span style="font-family:Times New Roman;font-size:11pt;color:#000000;font-style:normal;font-weight:normal;text-decoration:none;"&gt;&lt;span&gt;$1.52 billion&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11pt;"&gt; and a new &lt;/span&gt;&lt;span style="font-family:Times New Roman;font-size:11pt;color:#000000;font-style:normal;font-weight:normal;text-decoration:none;"&gt;&lt;span&gt;$377 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11pt;"&gt; net deferred tax asset.  The Company will amortize the net regulatory liability in accordance with applicable federal income tax laws, which require the amortization of a majority of the balance over the remaining regulatory life of the related property.  As a result of the modifications made to the annual transmission formula rate during the second quarter, the Company has recorded amortization of FERC jurisdictional net excess deferred tax liabilities, retroactive to January 1, 2018.  The Company continues to work with the ACC on a plan to amortize the remaining net excess deferred tax liabilities subject to its jurisdiction. See Note 3 for more details.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11pt;"&gt;&lt;span style="font-family:inherit;font-size:11pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11pt;"&gt;&lt;span style="font-family:inherit;font-size:11pt;"&gt;In August 2018, Treasury proposed regulations that clarify bonus depreciation transition rules under the Tax Act for regulated public utility property placed in service after September 27, 2017 and before January 1, 2018.  During the third quarter the Company recorded deferred tax liabilities of approximately &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11pt;"&gt;&lt;span&gt;$11 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11pt;"&gt; and an increase in its net regulatory liability for excess deferred taxes of approximately &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11pt;"&gt;&lt;span&gt;$9 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11pt;"&gt;, primarily related to bonus depreciation benefits claimed on the Company&#x2019;s 2017 tax return as a result of this clarifying guidance. However, the proposed regulations are ambiguous with respect to regulated public utility property placed in service on or after January 1, 2018. On December 20, 2018, the Joint Committee on Taxation (&#x201c;JCT&#x201d;)  released the general explanation of the Tax Act. The document - commonly referred to as the "Blue Book" - provides a comprehensive technical description of the Tax Act and includes the legislative intent of Congress with respect to the changes made by provisions of the Tax Act. The &#x201c;Blue Book&#x201d; provides clarification that the intent of the Tax Act was to exclude from the definition of bonus depreciation qualified property any property placed in service by a regulated public utility after December 31, 2017.  In a footnote, the JCT indicated that a technical correction bill may be necessary to reflect this intent.  &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11pt;"&gt;&lt;span style="font-family:inherit;font-size:11pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11pt;"&gt;&lt;span style="font-family:inherit;font-size:11pt;"&gt;Management recognizes tax positions which it believes are "more likely than not" to be sustained upon examination. In applying this "more likely than not" assessment, the Company is required to consider the technical merits of a position, including legislative intent.  As a result, while no legislation has been passed which clarifies the ambiguities related to bonus depreciation for property placed in service on or after January 1, 2018, the Company currently believes the continued availability of bonus depreciation is not "more likely than not" to be sustained upon examination. As a result, the Company has not recognized any current or deferred tax benefits related to bonus depreciation for property placed in service on or after January 1, 2018.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11pt;"&gt;&lt;span style="font-family:inherit;font-size:11pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11pt;"&gt;&lt;span style="font-family:inherit;font-size:11pt;"&gt;For the quarter ending March 31, 2018, the Company early adopted &#160;ASU 2018-02, Income Statement-Reporting Comprehensive Income: Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income and elected to reclassify the income tax effects of the Tax Act on items within accumulated other comprehensive income to retained earnings.

In December 2016, FERC approved a methodology for determining the amount of other postretirement benefit trust assets to transfer into a new trust account to pay for active union employee medical costs.  On January 2, 2018, these funds were moved to the new trust account, which is included in the other special use funds on the Consolidated Balance Sheets.  The Company and the IRS executed a final Closing Agreement on March 2, 2018.   The Company made an informational filing with FERC during February 2018.  It is the Company&#x2019;s understanding that completion of these regulatory requirements permits access to approximately &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$186 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; for the sole purpose of paying active union employee medical benefits.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;Pinnacle West uses a December&#160;31 measurement date each year for its pension and other postretirement benefit plans.&#160; The market-related value of our plan assets is their fair value at the measurement date.&#160; See Note 13 for further discussion of how fair values are determined.&#160; 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.&lt;/span&gt;&lt;/div&gt;&lt;div

style="font-family:inherit;font-size:11.5pt;"&gt;The Board of Directors has delegated oversight of the pension and other postretirement benefit plans&#x2019; assets to an Investment Management Committee (&#x201c;Committee&#x201d;).&#160; The Committee has adopted investment policy statements (&#x201c;IPS&#x201d;) for the pension and the other postretirement benefit plans&#x2019; assets.  The investment strategies for these plans include external management of plan assets, and prohibition of investments in Pinnacle West securities.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;The overall strategy of the pension plan&#x2019;s IPS is to achieve an adequate level of trust assets relative to the benefit obligations.&#160; To achieve this objective, the plan&#x2019;s investment policy provides for mixes of investments including long-term fixed income assets and return-generating assets.&#160; The target allocation between return-generating and long-term fixed income assets is defined in the IPS and is a function of the plan&#x2019;s funded status.&#160; The plan&#x2019;s funded status is reviewed on at least a monthly basis.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;Changes in the value of long-term fixed income assets, also known as liability-hedging assets, are intended to offset changes in the benefit obligations due to changes in interest rates.&#160; Long-term fixed income assets consist primarily of fixed income debt securities issued by the U.S. Treasury and other government agencies, U.S. Treasury Futures Contracts, and fixed income debt securities issued by corporations.&#160; Long-term fixed income assets may also include interest rate swaps, and other instruments.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;Return-generating assets are intended to provide a reasonable long-term rate of investment return with a prudent level of volatility.&#160; Return-generating assets are composed of U.S. equities, international equities, and alternative investments.&#160; International equities include investments in both developed and emerging markets.&#160; Alternative investments include investments in real estate, private equity and various other strategies.&#160; The plan may also hold investments in return-generating assets by holding securities in partnerships, common and collective trusts and mutual funds.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span

style="font-family:inherit;font-size:11.5pt;"&gt;See Note 13 for a discussion on the fair value hierarchy and how fair value methodologies are applied.&#160; The plans invest directly in fixed income, U.S. Treasury Futures Contracts, and equity securities, in addition to investing indirectly in fixed income securities, equity securities and real estate through the use of mutual funds, partnerships and common and collective trusts.&#160; Equity securities held directly by the plans are valued using quoted active market prices from the published exchange on which the equity security trades, and are classified as Level 1.&#160; U.S. Treasury Futures Contracts are valued using the quoted active market prices from the exchange on which they trade, and are classified as Level 1.  Fixed income securities issued by the U.S. Treasury held directly by the plans are valued using quoted active market prices, and are classified as Level 1.&#160; Fixed income securities issued by corporations, municipalities, and other agencies are primarily valued using quoted inactive market prices, or quoted active market prices for similar securities, or by utilizing calculations which incorporate observable inputs such as yield, maturity and credit quality.&#160; These instruments are classified as Level 2.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;Mutual funds, partnerships, and common and collective trusts are valued utilizing a net asset value (NAV) concept or its equivalent.  Mutual funds, &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11pt;"&gt;which includes exchange traded funds (ETFs), are &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;classified as Level 1 and valued using a NAV that is observable and based on the active market in which the fund trades.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; Common and collective trusts are maintained by banks or investment companies and hold certain investments in accordance with a stated set of objectives (such as tracking the performance of the S&amp;amp;P 500 Index).&#160; The trust's shares are offered to a limited group of investors, and are not traded in an active market.  Investments in common and collective trusts are valued using NAV as a practical expedient and, accordingly, are not classified in the fair value hierarchy.  The NAV for trusts investing in exchange traded equities, and fixed income securities is derived from the market prices of the underlying securities held by the trusts. The &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;NAV for trusts investing in real estate is derived from the appraised values of the trust's underlying real estate assets.&#160; As of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;December&#160;31, 2018&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;, the plans were able to transact in the common and collective trusts at NAV. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;Investments in partnerships are also valued using the concept of NAV as a practical expedient and, accordingly, are not classified in the fair value hierarchy.  The NAV for these investments is derived from the value of the partnerships' underlying assets.  The plan's partnerships holdings relate to investments in high-yield fixed income instruments and assets of privately held portfolio companies.  Certain partnerships also include funding commitments that may require the plan to contribute up to &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$75 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; to these partnerships; as of &lt;/span&gt;&lt;span

style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$62 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; of these commitments have been funded.

pricing services that utilize methodologies described to determine fair market value.&#160; We have internal control procedures to ensure this information is consistent with fair value accounting guidance.&#160; These procedures include assessing valuations using an independent pricing source, verifying that pricing can be supported by actual recent market transactions, assessing hierarchy classifications, comparing investment returns with benchmarks, and obtaining and reviewing independent audit reports on the trustee&#x2019;s internal operating controls and valuation processes.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:center;font-size:11.5pt;"&gt;&lt;span

earnings or losses on their investments.&#160; Under this plan, the Company matches a percentage of the participants&#x2019; contributions in cash which is then invested in the same investment mix as participants elect to invest their own future contributions.&#160; Pinnacle West recorded expenses for this plan of approximately &lt;/span&gt;&lt;span

style="font-family:inherit;font-size:11.5pt;"&gt;In 1986, APS entered into agreements with &lt;/span&gt;&lt;span

and lease back interests in Palo Verde Unit 2 and related common facilities.&#160; These lessor trust entities have been deemed VIEs for which APS is the primary beneficiary.&#160; As the primary beneficiary, APS consolidated these lessor trust entities.&#160; The impacts of these sale leaseback transactions are excluded from our lease disclosures as lease accounting is eliminated upon consolidation.&#160; See Note 18 for a discussion of VIEs.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span

lease for accounting purposes. This generally occurs when a purchased power contract designates a specific power plant from which the buyer purchases substantially all of the output and also meets other required lease accounting criteria.  APS has certain purchased power contracts that contain lease arrangements. The future minimum lease payments due under these contracts are &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$54 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;, all of which relate to 2019.  Due to the inherent uncertainty associated with the reliability of the fuel source, payments under most renewable purchased power lease contracts are considered contingent rents and are excluded from future minimum lease payments. See Note 10 for additional information on our purchased power contract estimated commitments. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:13px;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;Operating lease cost for purchased power lease contracts was &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$47 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; in 2018, &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$60 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; in 2017 and &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$82 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; in 2016. In addition, contingent rents for purchased power lease contracts was &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$109 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; in 2018, &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$100 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; in 2017, and &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$88 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; in 2016. These costs are recorded in fuel and purchased power on the Consolidated Statements of Income, and are subject to recovery under the PSA or RES. See Note 3.&lt;/span&gt;&lt;/div&gt;See Note 2 for a discussion of the new lease accounting standard we adopted on January 1, 2019.</us-gaap:LesseeOperatingLeasesTextBlock>

Amounts recovered in the lawsuit and settlement were recorded as adjustments to a regulatory liability and had no impact on the amount of reported net income.  &lt;/span&gt;&lt;span style="font-family:inherit;font-size:12pt;"&gt;In addition, the settlement agreement, as amended, provides APS with a method for submitting claims and getting recovery for costs incurred through December 31, 2019.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;APS has submitted four claims pursuant to the terms of the August 18, 2014 settlement agreement, for four separate time periods during July 1, 2011 through June 30, 2018. The DOE has approved and paid &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$74.2 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; for these claims (APS&#x2019;s share is &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$21.6 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;).   The amounts recovered were primarily recorded as adjustments to a regulatory liability and had no impact on reported net income.  In accordance with the 2017 Rate Case Decision, this regulatory liability is being refunded to customers (see Note 3).  APS's next claim pursuant to the terms of the August 18, 2014 settlement agreement was submitted to the DOE on October 31, 2018 in the amount of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$10.2 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; (APS's share is &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$3.0 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;).

Portions of these funds will be held in an escrow account and distributed to certain coal providers under the terms of the applicable coal supply agreements. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:center;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;Superfund-Related Matters&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;The Comprehensive Environmental Response Compensation and Liability Act ("CERCLA" or "Superfund") establishes liability for the cleanup of hazardous substances found contaminating the soil, water or air.&#160; Those who released, generated, transported to, or disposed of hazardous substances at a contaminated site are among the parties who are potentially responsible ("PRPs").&#160; PRPs may be strictly, and often are jointly and severally, liable for clean-up.  On September&#160;3, 2003, EPA advised APS that EPA considers APS to be a PRP in the Motorola 52&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;sup style="vertical-align:top;line-height:120%;font-size:pt"&gt;nd&lt;/sup&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;Street Superfund Site, Operable Unit 3 ("OU3") in Phoenix, Arizona.&#160; APS has facilities that are within this Superfund site.&#160; APS and Pinnacle West have agreed with EPA to perform certain investigative activities of the APS facilities within OU3.&#160; In addition, on September&#160;23, 2009, APS agreed with EPA and one other PRP to voluntarily assist with the funding and management of the site-wide groundwater remedial investigation and feasibility study ("RI/FS").&#160; Based upon discussions between the OU3 working group parties and EPA, along with the results of recent technical analyses prepared by the OU3 working group to supplement the RI/FS for OU3, APS anticipates finalizing the RI/FS in the fall or winter of 2019.  We estimate that our costs related to this investigation and study will be approximately &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$2 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;.&#160; 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 expenditures related to this matter cannot be reasonably estimated.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;On August&#160;6, 2013, Roosevelt Irrigation District ("RID") filed a lawsuit in Arizona District Court against APS and &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;24&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; other defendants, alleging that RID&#x2019;s groundwater wells were contaminated by the release of hazardous substances from facilities owned or operated by the defendants.&#160; The lawsuit also alleges that, under Superfund laws, the defendants are jointly and severally liable to RID.&#160; The allegations against APS arise out of APS&#x2019;s current and former ownership of facilities in and around OU3.&#160; As part of a state governmental investigation into groundwater contamination in this area, on January 25, 2015, ADEQ sent a letter to APS seeking information concerning the degree to which, if any, APS&#x2019;s current and former ownership of these facilities may have contributed to groundwater contamination in this area.&#160; APS responded to ADEQ on May 4, 2015.  On December 16, 2016, &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;two&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; RID environmental and engineering contractors filed an ancillary lawsuit for recovery of costs against APS and the other defendants in the RID litigation.  That same day, another RID service provider filed an additional ancillary CERCLA lawsuit against certain of the defendants in the main RID litigation, but excluded APS and certain other parties as named defendants.  Because the ancillary lawsuits concern past costs allegedly incurred by these RID vendors, which were ruled unrecoverable directly by RID in November of 2016, the additional lawsuits do not increase APS's exposure or risk related to these matters.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;On April 5, 2018, RID and the defendants in that particular litigation executed a settlement agreement, fully resolving RID's CERCLA claims concerning both past and future cost recovery.  APS's share of this settlement was immaterial.  In addition, the &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;two&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; environmental and engineering vendors voluntarily dismissed their lawsuit against APS and the other named defendants without prejudice.  An order to this effect was entered on April 17, 2018.  With this disposition of the case, the vendors may file their lawsuit again in the future.  In addition, APS and certain other parties not named in the remaining RID service provider lawsuit may be brought into the litigation via third-party complaints filed by the current direct defendants.  We are unable to predict the outcome of these matters; however, we do not expect the outcome to have a material impact on our financial position, results of operations or cash flows.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;Environmental Matters&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;APS is subject to numerous environmental laws and regulations affecting many aspects of its present and future operations, including air emissions of both conventional pollutants and greenhouse gases, water quality, wastewater discharges, solid waste, hazardous waste, and CCRs.&#160; These laws and regulations can change from time to time, imposing new obligations on APS resulting in increased capital, operating, and other costs.&#160; Associated capital expenditures or operating costs could be material.&#160; APS intends to seek recovery of any such environmental compliance costs through our rates, but cannot predict whether it will obtain such recovery.&#160; The following proposed and final rules&#160;involve material compliance costs to APS.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-style:italic;font-weight:bold;"&gt;Regional Haze Rules.&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;&#160;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; APS has received the final rulemaking imposing new pollution control requirements on Four Corners and the Navajo Plant.  EPA will require these plants to install pollution control equipment that constitutes BART to lessen the impacts of emissions on visibility surrounding the plants.  In addition, EPA issued a final rule for Regional Haze compliance at Cholla that does not involve the installation of new pollution controls and that will replace an earlier BART determination for this facility.  See below for details of the Cholla BART approval.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-style:italic;"&gt;Four Corners.  &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;Based on EPA&#x2019;s final standards, APS's &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;63%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; share of the cost of required controls for Four Corners Units 4 and 5 is approximately &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$400 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;, the majority of which has already been incurred.&#160; In addition, APS and El Paso entered into an asset purchase agreement providing for the purchase by APS, or an affiliate of APS, of El Paso's &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;7%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; interest in Four Corners Units 4 and 5.  4CA purchased the El Paso interest on July 6, 2016.  NTEC purchased the interest from 4CA on July 3, 2018.  See "Four Corners Coal Supply Agreement - 4CA Matter" below for a discussion of the NTEC purchase.  The cost of the pollution controls related to the &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;7%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; interest is approximately &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$45 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;, which was assumed by NTEC through its purchase of the &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;7%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; interest.  &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-style:italic;"&gt;Navajo Plant.  &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;APS estimates that its share of costs for upgrades at the Navajo Plant, based on EPA&#x2019;s Federal Implementation Plan ("FIP"), could be up to approximately &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$200 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;; however, given the future plans for the Navajo Plant, we do not expect to incur these costs.&#160; See "Navajo Plant" in Note 3 for information regarding future plans for the Navajo Plant.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-style:italic;"&gt;Cholla&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;.  APS believed that EPA&#x2019;s original 2012 final rule&#160;establishing controls constituting BART for Cholla, which would require installation of SCR controls, was unsupported and that EPA had no basis for disapproving Arizona&#x2019;s State Implementation Plan ("SIP") and promulgating a FIP that was inconsistent with the state&#x2019;s considered BART determinations under the regional haze program.&#160; In September 2014, APS met with EPA to propose a compromise BART strategy, whereby APS would permanently close Cholla Unit 2 and cease burning coal at Units 1 and 3 by the mid-2020s.  (See Note 3 for details related to the resulting regulatory asset.)  APS made the proposal with the understanding that additional emission control equipment is unlikely to be required in the future because retiring and/or converting the units as contemplated in the proposal is more &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;cost effective than, and will result in increased visibility improvement over, the BART requirements for oxides of nitrogen ("NOx") imposed through EPA's BART FIP.  In early 2017, EPA approved a final rule incorporating APS's compromise proposal, which took effect for Cholla on April 26, 2017.  &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-style:italic;font-weight:bold;"&gt;Coal Combustion Waste&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;.&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;  On December 19, 2014, EPA issued its final regulations governing the handling and disposal of CCR, such as fly ash and bottom ash.  The rule regulates CCR as a non-hazardous waste under Subtitle D of the Resource Conservation and Recovery Act ("RCRA") and establishes national minimum criteria for existing and new CCR landfills and surface impoundments and all lateral expansions consisting of location restrictions, design and operating criteria, groundwater monitoring and corrective action, closure requirements and post closure care, and recordkeeping, notification, and internet posting requirements.  The rule generally requires any existing unlined CCR surface impoundment that is contaminating groundwater above a regulated constituent&#x2019;s groundwater protection standard to stop receiving CCR and either retrofit or close, and further requires the closure of any CCR landfill or surface impoundment that cannot meet the applicable performance criteria for location restrictions or structural integrity.  Such closure requirements are deemed "forced closure" or "closure for cause" of unlined surface impoundments, and are the subject of recent regulatory and judicial activities described below.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;On December 16, 2016, President Obama signed the Water Infrastructure Improvements for the Nation ("WIIN") Act into law, which contains a number of provisions requiring EPA to modify the self-implementing provisions of the Agency's current CCR rules under Subtitle D.  Such modifications include new EPA authority to directly enforce the CCR rules through the use of administrative orders and providing states, like Arizona, where the Cholla facility is located, the option of developing CCR disposal unit permitting programs, subject to EPA approval.  For facilities in states that do not develop state-specific permitting programs, EPA is required to develop a federal permit program, pending the availability of congressional appropriations.  By contrast, for facilities located within the boundaries of Native American tribal reservations, such as the Navajo Nation, where the Navajo Plant and Four Corners facilities are located, EPA is required to develop a federal permit program regardless of appropriated funds.  &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;ADEQ has initiated a process to evaluate how to develop a state CCR permitting program that would cover electric generating units ("EGUs"), including Cholla.  While APS has been working with ADEQ on the development of this program, we are unable to predict when Arizona will be able to finalize and secure EPA approval for a state-specific CCR permitting program.  With respect to the Navajo Nation, APS has sought clarification as to when and how EPA would be initiating permit proceedings for facilities on the reservation, including Four Corners.  We are unable to predict at this time when EPA will be issuing CCR management permits for the facilities on the Navajo Nation.  At this time, it remains unclear how the CCR provisions of the WIIN Act will affect APS and its management of CCR.  &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;Based upon utility industry petitions for EPA to reconsider the RCRA Subtitle D regulations for CCR, which were premised in part on the CCR provisions of the 2016 WIIN Act, on September 13, 2017 EPA agreed to evaluate whether to revise these federal CCR regulations.  On July 17, 2018, EPA finalized a revision to its RCRA Subtitle D regulations for CCR, the "Phase I, Part I" revision to its CCR regulations, deferring for future action a number of other proposed changes contemplated in a March 1, 2018 proposal.  For the final rule issued on July 17, 2018, EPA established nationwide health-based standards for certain constituents of CCR subject to groundwater corrective action and delayed the closure deadlines for certain unlined CCR surface impoundments by 18 months (for example, those disposal units required to undergo forced closure).  These changes to the federal regulations governing CCR disposal are unlikely to have a material impact on APS.  As for those aspects of the March 2018 rulemaking proposal for which EPA has yet to take final action, it remains unclear which specific provisions of the federal CCR rules will ultimately be modified, how they will be modified, or when such modification will occur.  &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;Pursuant to a June 24, 2016 order by the D.C. Circuit Court of Appeals in the litigation by industry- and environmental-groups challenging EPA&#x2019;s CCR regulations, EPA is required to complete a rulemaking proceeding in the near future concerning whether or not boron must be included on the list of groundwater constituents that might trigger corrective action under EPA&#x2019;s CCR rules.&#160; Simultaneously with the issuance of EPA's proposed modifications to the federal CCR rules in response to industry petitions, on March 1, 2018, EPA issued a proposed rule seeking comment as to whether or not boron should be included on this list.  EPA is not required to take final action approving the inclusion of boron.&#160; Should EPA take final action adding boron to the list of groundwater constituents that might trigger corrective action, any resulting corrective action measures may increase APS's costs of compliance with the CCR rule at our coal-fired generating facilities.&#160; At this time APS cannot predict the eventual results of this rulemaking proceeding concerning boron.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;On August 21, 2018, the D.C. Circuit Court issued its decision on the merits in this litigation.  The Court upheld the legality of EPA&#x2019;s CCR regulations, though it vacated and remanded back to EPA a number of specific provisions, which are to be corrected in accordance with the Court&#x2019;s order.  Among the issues affecting APS&#x2019;s management of CCR, the D.C. Circuit&#x2019;s decision vacated and remanded those provisions of the EPA CCR regulations that allow for the operation of unlined CCR surface impoundments, even where those unlined impoundments have not otherwise violated a regulatory location restriction or groundwater protection standard (i.e., otherwise triggering forced closure).  At this time, it remains unclear how this D.C. Circuit Court decision will affect APS&#x2019;s operations or any financial impacts, as EPA has yet to take regulatory action on remand to revise its 2015 CCR regulations consistent with the Court&#x2019;s order. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;Based on this decision, on December 17, 2018, certain environmental groups filed an emergency motion with the D.C. Circuit to either stay or summarily vacate EPA's July 17, 2018 final rule extending the closure-initiation deadline for certain unlined CCR surface impoundments until October 2020.  In response, EPA filed a motion to remand but not vacate that deadline extension regulation.  We cannot predict the outcome of the D.C. Circuit's consideration of these dueling motions, and whether or how such a ruling would affect APS's operations.  &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;APS currently disposes of CCR in ash ponds and dry storage areas at Cholla and Four Corners.  APS estimates that its share of incremental costs to comply with the CCR rule for Four Corners is approximately &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$22 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; and its share of incremental costs to comply with the CCR rule for Cholla is approximately &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$20 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;.  The Navajo Plant currently disposes of CCR in a dry landfill storage area.  APS estimates that its share of incremental costs to comply with the CCR rule for the Navajo Plant is approximately &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$1 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;.  Additionally, the CCR rule requires ongoing, phased groundwater monitoring.  By October 17, 2017, electric utility companies that own or operate CCR disposal units, such as APS, must have collected sufficient groundwater sampling data to initiate a detection monitoring program.&#160; To the extent that certain threshold constituents are identified through this initial detection monitoring at levels above the CCR rule&#x2019;s standards, the rule required the initiation of an assessment monitoring program by April 15, 2018.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;APS recently completed the statistical analyses for its CCR disposal units that triggered assessment monitoring.  APS determined that several of its CCR disposal units at Cholla and Four Corners will need to undergo corrective action.  In addition, all such units must cease operating and initiate closure by October of 2020.  APS currently estimates that the additional incremental costs to complete this corrective action and closure work, along with the costs to develop replacement CCR disposal capacity, could be approximately &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$5 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; for both Cholla and Four Corners.  APS initiated an assessment of corrective measures on January 14, 2019, and anticipates completing this assessment during the summer of 2019.  During this assessment, APS will gather additional groundwater data, solicit input from the public, host public hearings, and select remedies.  As such, this &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$5 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; cost estimate may change based upon APS&#x2019;s performance of the CCR rule&#x2019;s corrective action assessment process.  Given uncertainties that may exist until we have fully completed the corrective &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;action assessment process, we cannot predict any ultimate impacts to the Company; however, at this time we do not believe any potential change to the cost estimate would have a material impact on our financial position, results of operations or cash flows.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-style:italic;font-weight:bold;"&gt;Clean Power Plan.&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;  On June 2, 2014, EPA issued two proposed rules to regulate greenhouse gas ("GHG") emissions from modified and reconstructed EGUs pursuant to Section 111(b) of the Clean Air Act and existing fossil fuel-fired power plants pursuant to Clean Air Act Section 111(d).  On August 3, 2015, EPA finalized carbon pollution standards for EGUs, the "Clean Power Plan".  On October 10, 2017, EPA issued a proposal to repeal the Clean Power Plan and proposed replacement regulations on August 21, 2018.  In addition, judicial challenges to the Clean Power Plan are pending before the D.C. Circuit, though that litigation is currently in abeyance while EPA develops regulatory action to potentially repeal and replace that regulation.  &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;EPA's pending proposal to regulate carbon emissions from EGUs replaces the Clean Power Plan with standards that are based entirely upon measures that can be implemented to improve the heat rate of steam-electric power plants, specifically coal-fired EGUs.  In contrast with the Clean Power Plan, EPA's proposed "Affordable Clean Energy Rule" would not involve utility-level generation dispatch shifting away from coal-fired generation and toward renewable energy resources and natural gas-fired combined cycle power plants.  In addition, to address the New Source Review ("NSR") implications of power plant upgrades potentially necessary to achieve compliance with the proposed Affordable Clean Energy Rule standards, EPA also proposed to revise EPA's NSR regulations to more readily authorize the implementation of EGU efficiency upgrades.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;We cannot predict the outcome of EPA's regulatory actions related to the August 2015 carbon pollution standards for EGU's, including any actions related to EPA's repeal proposal for the Clean Power Plan or additional rulemaking actions to approve the EPA's recently proposed Affordable Clean Energy Rule.  In addition, we cannot predict whether the D.C. Circuit Court will continue to hold the litigation challenging the original Clean Power Plan in abeyance in light of EPA's repeal proposal, which is still pending.  &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;Other environmental rules&#160;that could involve material compliance costs include those related to effluent limitations, the ozone national ambient air quality standard and other rules&#160;or matters involving the Clean Air Act, Clean Water Act, Endangered Species Act, RCRA, Superfund, the Navajo Nation, and water supplies for our power plants.&#160; The financial impact of complying with current and future environmental rules&#160;could jeopardize the economic viability of our coal plants or the willingness or ability of power plant participants to fund any required equipment upgrades or continue their participation in these plants.&#160; The economics of continuing to own certain resources, particularly our coal plants, may deteriorate, warranting early retirement of those plants, which may result in asset impairments.&#160; APS would seek recovery in rates for the book value of any remaining investments in the plants as well as other costs related to early retirement, but cannot predict whether it would obtain such recovery.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;Federal Agency Environmental Lawsuit Related to Four Corners &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"/&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;On April 20, 2016, several environmental groups filed a lawsuit against OSM and other federal agencies in the District of Arizona in connection with their issuance of the approvals that extended the life of Four Corners and the adjacent mine.&#160; The lawsuit alleges that these federal agencies violated both the Endangered Species Act ("ESA") and the National Environmental Policy Act ("NEPA") in providing the federal approvals necessary to extend operations at the Four Corners Power Plant and the adjacent Navajo Mine past July 6, 2016.&#160; APS filed a motion to intervene in the proceedings, which was granted on August 3, 2016.  &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;On September 15, 2016, NTEC, the company that owns the adjacent mine, filed a motion to intervene for the purpose of dismissing the lawsuit based on NTEC's tribal sovereign immunity.  On September 11, 2017, the Arizona District Court issued an order granting NTEC's motion, dismissing the litigation with prejudice, and terminating the proceedings.  On November 9, 2017, the environmental group plaintiffs appealed the district court order dismissing their lawsuit.  Oral argument for this appeal has been scheduled for March 2019.  We cannot predict whether this appeal will be successful and, if it is successful, the outcome of further district court proceedings.  &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;Four Corners National Pollutant Discharge Elimination System ("NPDES") Permit&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-style:italic;font-weight:bold;"/&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;On July 16, 2018, several environmental groups filed a petition for review before the EPA Environmental Appeals Board ("EAB") concerning the NPDES wastewater discharge permit for Four Corners, which was reissued on June 12, 2018.&#160; The environmental groups allege that the permit was reissued in contravention of several requirements under the Clean Water Act and did not contain required provisions concerning EPA&#x2019;s 2015 revised effluent limitation guidelines for steam-electric EGUs, 2014 existing-source regulations governing cooling-water intake structures, and effluent limits for surface seepage and subsurface discharges from coal-ash disposal facilities.&#160; To address certain of these issues through a reconsidered permit, EPA took action on December 19, 2018 to withdraw the NPDES permit reissued in June 2018.  Withdrawal of the permit moots the EAB appeal, and EPA filed a motion to dismiss on that basis.  EPA indicated that it anticipates proposing a replacement NPDES permit by March 2019 and, depending on the extent of public comments concerning that proposal, taking final action on a new NPDES permit by June 2019.  At this time, we cannot predict the outcome of EPA's reconsideration of the NPDES permit and whether reconsideration will have a material impact on our financial position, results of operations or cash flows. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;Four Corners Coal Supply Agreement &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;Arbitration&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;On June 13, 2017, APS received a Demand for Arbitration from NTEC in connection with the Coal Supply Agreement, dated December 30, 2013, under which NTEC supplies coal to APS and the other Four Corners owners (collectively, the &#x201c;Buyer&#x201d;) for use at the Four Corners Power Plant (the "2016 Coal Supply Agreement").  NTEC was originally seeking a declaratory judgment to support its interpretation of a provision regarding uncontrollable forces in the agreement that relates to annual minimum quantities of coal to be purchased by the Buyer.  NTEC also alleged a shortfall in the Buyer&#x2019;s purchases for the initial contract year of approximately &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$30 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;.  APS&#x2019;s share of this amount is approximately &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$17 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;.  On September 20, 2017, NTEC amended its Demand for Arbitration, removing its request for a declaratory judgment and at such time was only seeking relief for the alleged shortfall in the Buyer's purchases for the initial contract year. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;On June 29, 2018, the parties settled the dispute for &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$45 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;, which includes settlement for the initial contract year and the current contract year.  APS&#x2019;s share of this amount is approximately &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$34 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;.  In connection with the settlement, the parties amended the 2016 Coal Supply Agreement, including modifying the provisions that gave rise to this dispute.   (See &#x201c;4CA Matter&#x201d; below for additional matters agreed to between 4CA and NTEC in the settlement arrangement.)  The arbitration was dismissed on July 9, 2018.  &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"/&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;Coal Advance Purchase&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;On March 12, 2018, APS paid to NTEC approximately &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$24 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; as an advance payment for APS&#x2019;s share of coal under the 2016 Coal Supply Agreement.  The coal inventory purchased represents an amount that APS expects to use for its plant operations within the next year.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;4CA Matter&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:13px;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;On July 6, 2016, 4CA purchased El Paso&#x2019;s &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;7%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; interest in Four Corners.  NTEC had the option to purchase the &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;7%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; interest within a certain timeframe pursuant to an option granted to NTEC.  On December 29, 2015, NTEC provided notice of its intent to exercise the option.  The purchase did not occur during the originally contemplated timeframe.  Concurrent with the settlement of the 2016 Coal Supply Agreement matter described above, NTEC and 4CA agreed to allow for the purchase by NTEC of the &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;7%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; interest, consistent with the option.  On June 29, 2018, 4CA and NTEC entered into an asset purchase agreement providing for the sale to NTEC of 4CA's &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;7%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; interest in Four Corners.  Completion of the sale was subject to the receipt of approval by FERC, which was received on July 2, 2018, and the sale transaction closed on July 3, 2018.  NTEC purchased the &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;7%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; interest at 4CA&#x2019;s book value, approximately &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$70 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;, and will pay 4CA the purchase price over a period of four years pursuant to a secured interest-bearing promissory note.  In connection with the sale, Pinnacle West guaranteed certain obligations that NTEC will have to the other owners of Four Corners, such as NTEC's &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;7%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; share of capital expenditures and operating and maintenance expenses.  Pinnacle West's guarantee is secured by a portion of APS's payments to be owed to NTEC under the 2016 Coal Supply Agreement.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:13px;text-align:left;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;The 2016 Coal Supply Agreement contained alternate pricing terms for the &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;7%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; interest in the event NTEC did not purchase the interest.  Until the time that NTEC purchased the &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;7%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; interest, the alternate pricing provisions were applicable to 4CA as the holder of the &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;7%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; interest.  These terms included a formula under which NTEC must make certain payments to 4CA for reimbursement of operations and maintenance costs and a specified rate of return, offset by revenue generated by 4CA&#x2019;s power sales.  Such payments are due to 4CA at the end of each calendar year.  A &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$10 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; payment was due to 4CA at December 31, 2017, which NTEC satisfied by directing to 4CA a prepayment from APS of a portion of a future mine reclamation obligation.  The balance of the amount under this formula due December 31, 2018 for calendar year 2017 is approximately &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$20 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;, which was paid to 4CA on December 14, 2018.  The balance of the amount under this formula at December 31, 2018 for calendar year 2018 (up to the date that NTEC purchased the &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;7%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; interest) is approximately &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;$10 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;, which is due to 4CA at December 31, 2019.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;Financial Assurances&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;In the normal course of business, we obtain standby letters of credit and surety bonds from financial institutions and other third parties.

A maximum obligation is not&lt;/span&gt;&lt;/div&gt;explicitly stated in the guarantee and, therefore, the overall maximum amount of the obligation under such guarantee cannot be reasonably estimated; however, we consider the fair value of this guarantee to be immaterial.</us-gaap:CommitmentsAndContingenciesDisclosureTextBlock>

These instruments are typically structured as investment companies offering shares or units to multiple investors for the purpose of providing a return. These instruments are similar to mutual funds; however, their NAV is generally not published and publicly available, nor are these instruments traded on an exchange.  Instruments valued using NAV, as a practical expedient are included in our fair value disclosures however, in accordance with GAAP are not classified within the fair value hierarchy levels.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;Recurring Fair Value Measurements&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;We apply recurring fair value measurements to cash equivalents, derivative instruments, and investments held in the nuclear decommissioning trust and other special use funds.

Derivative Instruments&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;Exchange traded commodity contracts are valued using unadjusted quoted prices.&#160; For non-exchange traded commodity contracts, we calculate fair value based on the average of the bid and offer price, discounted to reflect net present value.&#160; We maintain certain valuation adjustments for a number of risks associated with the valuation of future commitments.&#160; These include valuation adjustments for liquidity and credit risks.&#160; The liquidity valuation adjustment represents the cost that would be incurred if all unmatched positions were closed out or hedged.&#160; The credit valuation adjustment represents estimated credit losses on our net exposure to counterparties, taking into account netting agreements, expected default experience for the credit rating of the counterparties and the overall diversification of the portfolio.&#160; We maintain credit policies that management believes minimize overall credit risk.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;Certain non-exchange traded commodity contracts are valued based on unobservable inputs due to the long-term nature of contracts, characteristics of the product, or the unique location of the transactions.&#160; 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.&#160; We rely primarily on broker quotes to value these instruments.&#160; When our valuations utilize broker quotes, we perform various control procedures to ensure the quote has been developed consistent with fair value accounting guidance.&#160; These controls include assessing the quote for reasonableness by comparison against other broker quotes, reviewing historical price relationships, and assessing market activity.&#160; When broker quotes are not available, the primary valuation technique used to calculate the fair value is the extrapolation of forward pricing curves using observable market data for more liquid delivery points in the same region and actual transactions at more illiquid delivery points.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;When the unobservable portion is significant to the overall valuation of the transaction, the entire transaction is classified as Level 3.&#160; Our classification of instruments as Level 3 is primarily reflective of the long-term nature of our energy transactions.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;Our energy risk management committee, consisting of officers and key management personnel, oversees our energy risk management activities to ensure compliance with our stated energy risk management policies.&#160; We have a risk control function that is responsible for valuing our derivative commodity instruments in accordance with established policies and procedures.&#160; The risk control function reports to the chief financial officer&#x2019;s organization.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;Investments Held in Nuclear Decommissioning Trust and Other Special Use Funds&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;The nuclear decommissioning trust and other special use funds invest in fixed income and equity securities.  Other special use funds include the coal reclamation escrow account and the active union medical trust.

Our trustees and escrow agent use pricing services that utilize the valuation methodologies described below to determine fair market value. We have internal control procedures designed to ensure this information is consistent with fair value accounting guidance. These procedures include assessing valuations using an independent pricing source, verifying that pricing can be supported by actual recent market transactions, assessing hierarchy classifications, comparing investment returns with benchmarks, and obtaining and reviewing independent audit reports on the trustees&#x2019; and escrow agent's internal operating controls and valuation processes.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-style:italic;font-weight:bold;"&gt;Fixed Income Securities&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;Fixed income securities issued by the U.S. Treasury are valued using quoted active market prices and are typically classified as Level 1.&#160; Fixed income securities issued by corporations, municipalities, and other agencies, including mortgage-backed instruments, are valued using quoted inactive market prices, quoted active market prices for similar securities, or by utilizing calculations which incorporate observable inputs such as yield curves and spreads relative to such yield curves.&#160; These fixed income instruments are classified as Level 2.&#160; Whenever possible, multiple market quotes are obtained which enables a cross-check validation.&#160; A primary price source is identified based on asset type, class, or issue of securities.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;Fixed income securities may also include short-term investments in certificates of deposit, variable rate notes, time deposit accounts, U.S. Treasury and Agency obligations, U.S. Treasury repurchase agreements, commercial paper, and other short term instruments. These instruments are valued using active market prices or utilizing observable inputs described above.  &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-style:italic;font-weight:bold;"&gt;Equity Securities&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;The nuclear decommissioning trust's equity security investments are held indirectly through commingled funds.&#160; The commingled funds are valued using the funds' NAV as a practical expedient.  The funds' NAV is primarily derived from the quoted active market prices of the underlying equity securities held by the funds.  We may transact in these commingled funds on a semi-monthly basis at the NAV.&#160; The commingled funds are maintained by a bank and hold investments in accordance with the stated objective of tracking the performance of the S&amp;amp;P 500 Index.&#160; Because the commingled funds' shares are offered to a limited group of investors, they are not considered to be traded in an active market.  As these instruments are valued using NAV, as a practical expedient, they have not been classified within the fair value hierarchy.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;The nuclear decommissioning trust and other special use funds may also hold equity securities that include exchange traded mutual funds and money market accounts for short-term liquidity purposes.  These short-term, highly-liquid, investments are valued using active market prices. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span

Awardees elect to receive payment in either &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;100%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; stock, &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;100%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; cash, or &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;50%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; in cash and &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;50%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; in stock.&#160;Restricted stock unit awards typically include a dividend equivalent feature. This feature allows each award to accrue dividend rights equal to the dividends they would have received had they directly owned the stock. Interest on dividend rights compounds quarterly. If the award is forfeited the employee is not entitled to the dividends on those shares.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;In December&#160;2012, the Company granted a retention award of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;50,617&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; performance-linked restricted stock units to the Chairman of the Board and Chief Executive Officer of Pinnacle West.&#160; This award vested on December&#160;31, 2016, because he remained employed with the Company through that date. &#160;The Board did increase the number of awards that vested by &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;33,745&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; restricted stock units, payable in stock because certain performance requirements were met.  In February 2017, &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;84,362&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; restricted stock units were released.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;Compensation cost for restricted stock unit awards is based on the fair value of the award, with the fair value being the market price of our stock on the measurement date.  Restricted stock unit awards that will be settled in cash are accounted for as liability awards, with compensation cost initially calculated on the date of grant using the Company&#x2019;s closing stock price, and remeasured at each balance sheet date. Restricted stock unit awards that will be settled in shares are accounted for as equity awards, with compensation cost calculated using the Company's closing stock price on the date of grant.  Compensation cost is recognized over the requisite service period based on the fair value of the award. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;Stock grants are issued to non-officer members of the Board of Directors.  They may elect to receive the stock grant, or to defer receipt until a later date and receive stock units in lieu of the stock grant.&#160; The members of the Board of Directors who elect to defer may elect to receive payment in either &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;100%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; stock,   &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;100%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; cash, or &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;50%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; in cash and &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;50%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; in stock.&#160; Each stock unit is convertible to one share of stock. The stock units accrue dividend rights, equal to the amount of dividends the Directors would have received had they directly owned stock equal to the number of vested restricted stock units or stock units from the date of grant to the date of payment, plus interest compounded quarterly.&#160; The dividends and interest are paid, based on the Director&#x2019;s election, in either stock, cash, or &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;50%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; in cash and &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;50%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; in stock.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;Performance Share Awards&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;Performance share awards are granted to officers and key employees.&#160; The awards contain &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;two&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; separate performance criteria that affect the number of shares that may be received if after the end of a &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;3&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;-year performance period the performance criteria are met.  For the first criteria, the number of shares that will vest is based on non-financial performance metrics (i.e., the metric component). The other criteria is based upon Pinnacle West's total shareholder return ("TSR") in relation to the TSR of other companies in a specified utility index (i.e., the TSR component). The exact number of shares issued will vary from &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;0%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; to &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&lt;span&gt;200%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; of the target award.&#160; Shares received include dividend rights paid in stock equal to the amount of dividends that recipients would have received had they directly owned stock, equal to the number of vested performance shares from the date of grant to the date of payment plus interest compounded quarterly.  If the award is forfeited or if the performance criteria are not achieved, the employee is not entitled to the dividends on those shares.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;Performance share awards are accounted for as equity awards, with compensation cost based on the fair value of the award on the grant date. Compensation cost relating to the metric component of the award is based on the Company&#x2019;s closing stock price on the date of grant, with compensation cost recognized over the requisite service period based on the number of shares expected to vest. Management evaluates the probability of meeting the metric component at each balance sheet date. If the metric component criteria are not ultimately achieved, no compensation cost is recognized relating to the metric component, and any previously recognized compensation cost is reversed.  Compensation cost relating to the TSR component of the award is determined using a Monte Carlo simulation valuation model, with compensation cost recognized ratably over the requisite service period, regardless of the number of shares that actually vest.</us-gaap:DisclosureOfCompensationRelatedCostsShareBasedPaymentsTextBlock>

style="font-family:inherit;font-size:11.5pt;"&gt;Derivative financial instruments are used to manage exposure to commodity price and transportation costs of electricity, natural gas, coal, emissions allowances and interest rates.&#160; Risks associated with market volatility are managed by utilizing various physical and financial derivative instruments, including futures, forwards, options and swaps.&#160; As part of our overall risk management program, we may use derivative instruments to hedge purchases and sales of electricity and fuels.&#160; Derivative instruments that meet certain hedge accounting criteria may be designated as cash flow hedges and are used to limit our exposure to cash flow variability on forecasted transactions.&#160; The changes in market value of such instruments have a high correlation to price changes in the hedged transactions.&#160; Derivative instruments are also entered into for economic hedging purposes.&#160; While economic hedges may mitigate exposure to fluctuations in commodity prices, these instruments have not been designated as accounting hedges.&#160; Contracts that have the same terms (quantities, delivery points and delivery periods) and for which power does not flow are netted, which reduces both revenues and fuel and purchased power costs in our Consolidated Statements of Income, but does not impact our financial condition, net income or cash flows.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:center;font-size:11.5pt;"&gt;&lt;span

style="font-family:inherit;font-size:11.5pt;"&gt;Our derivative instruments, excluding those qualifying for a scope exception, are recorded on the balance sheet as an asset or liability and are measured at fair value.&#160; See Note 13 for a discussion of fair value measurements.&#160; Derivative instruments may qualify for the normal purchases and normal sales scope exception if they require physical delivery and the quantities represent those transacted in the normal course of business.&#160; Derivative instruments qualifying for the normal purchases and sales scope exception are accounted for under the accrual method of accounting and excluded from our derivative instrument discussion and disclosures below.&lt;/span&gt;&lt;/div&gt;&lt;div

losses on derivatives pursuant to the PSA mechanism that would otherwise be recognized in income.&#160; 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).&#160; Gains and losses from derivatives in the following tables represent the amounts reflected in income before the effect of PSA

style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;Our derivative transactions are typically executed under standardized or

Agreements that allow for the offsetting of positive and negative exposures associated with a single counterparty are considered master netting arrangements.&#160; Transactions with counterparties that have master netting arrangements are offset and reported net on the Consolidated Balance Sheets.&#160; Transactions that do not allow for offsetting of positive and negative positions are

receivables and trade payables arising from settled positions, and other forms of non-cash collateral (such as letters of credit).&#160; These types of transactions are excluded from the offsetting

Counterparties in the portfolio consist principally of financial institutions, major energy companies, municipalities and local distribution companies.&#160; We maintain credit policies that we believe minimize overall credit risk to within acceptable limits.&#160; 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.&#160; 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.&#160; Valuation adjustments are established representing our estimated credit losses on our overall exposure to counterparties.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;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.&#160; Adequate assurance provisions allow a counterparty with reasonable grounds for uncertainty to demand additional collateral based on subjective events and/or conditions.&#160; 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&#160;&amp;amp; Poor&#x2019;s or Fitch or Baa3 for Moody&#x2019;s).&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;The following table provides information about our derivative instruments that have credit-risk-related contingent features at &lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;December&#160;31, 2018&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;

payments to the VIEs&#x2019; noncontrolling equity participants and take title to the leased Unit 2 interests, which, if appropriate, may be required to be written down in value.&#160; If such an

Because of the ability of APS to recover decommissioning costs in rates, and in accordance with the regulatory treatment, APS has deferred realized and unrealized gains and losses (including other-than-temporary impairments) in other regulatory liabilities. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:11.5pt;"&gt;&lt;span style="font-family:inherit;font-size:11.5pt;font-weight:bold;"&gt;Coal Reclamation Escrow Accounts -&lt;/span&gt;&lt;span style="font-family:inherit;font-size:11.5pt;"&gt; APS has investments restricted for the future coal mine reclamation funding related to Four Corners. This escrow account is primarily invested in fixed income securities. Earnings and proceeds from sales of securities are reinvested in the escrow account. Because of the ability of APS to recover coal reclamation costs in rates, and in accordance with the regulatory treatment, APS has deferred realized and unrealized gains and losses (including other-than-temporary impairments) in other regulatory liabilities.

These investments were transferred from APS other postretirement benefit trust assets into the active union employee medical trust in January 2018 (see Note 7). These investments may be used to pay active union employee medical costs incurred in the current period and in future periods. The account is invested primarily in fixed income securities. In accordance with the ratemaking treatment, APS has deferred the unrealized gains and losses (including other-than-temporary impairments) in other regulatory assets. &lt;/span&gt;&lt;span

The new revenue guidance requires entities to recognize revenue when control of the promised good or service is transferred to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. We applied the new guidance using the modified retrospective method applied to contracts which were not completed as of January 1, 2018. The adoption of the new revenue guidance resulted in expanded disclosures but otherwise did not have a material impact on our financial statements. New revenue disclosures required by the standard are included below, and in Note 1.  See Note 2 for additional information regarding the new accounting standard.  &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;padding-left:48px;font-size:11pt;"&gt;&lt;span

This includes sales of electricity to our regulated retail customers and wholesale and transmission activities.

This relates primarily to certain regulatory cost recovery mechanisms that are considered alternative revenue programs. We recognize revenue associated with alternative revenue programs when specific events permitting recognition are completed. Certain amounts associated with alternative revenue programs will subsequently be billed to customers; however, we do not reclassify billed amounts into revenue from contracts with customers.

Such costs are capitalized if they meet both of the following criteria: a. It is probable that future revenue in an amount at least equal to the capitalized cost will result from inclusion of that cost in allowable costs for rate-making purposes. b. Based on available evidence, the future revenue will be provided to permit recovery of the previously incurred cost rather than to provide for expected levels of similar future costs. If the revenue will be provided through an automatic rate-adjustment clause, this criterion requires that the regulator's intent clearly be to permit recovery of the previously incurred cost.</p></div>

BCE is a subsidiary that was formed in 2014 that focuses on growth opportunities that leverage the Company's core expertise in the electric energy industry.  BCE is currently pursuing transmission opportunities through a joint venture arrangement.  4CA is a subsidiary that was formed in 2016 as a result of the purchase of El Paso's </span><span style="font-family:inherit;font-size:11.5pt;"><span>7%</span></span><span style="font-family:inherit;font-size:11.5pt;"> interest in Four Corners.

Beginning in the quarter ended March 31, 2018, APS changed the format of presentation of its Consolidated Statements of Income from a utility ratemaking format to a commercial format.  Minor changes were made in the description of certain income statement line items and the amounts presented in the comparable prior period also changed by immaterial amounts due to the change from a utility to a non-utility format and also from the adoption of the new accounting guidance for net periodic pension cost and net periodic postretirement benefit cost.  In addition, the prior year amounts were reclassified to conform to the current year presentation for the other special use funds in the investment and other assets section on the Consolidated Balance Sheets.</span></div><div style="line-height:120%;text-indent:96px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-weight:bold;">Accounting Records and Use of Estimates</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">Our accounting records are maintained in accordance with accounting principles generally accepted in the United States of America ("GAAP").&#160; 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.&#160; Actual results could differ from those estimates.</span></div><div style="line-height:120%;text-align:center;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-weight:bold;">Regulatory Accounting</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">APS is regulated by the ACC and FERC.&#160; The accompanying financial statements reflect the rate-making policies of these commissions.&#160; As a result, we capitalize certain costs that would be included as expense in the current period by unregulated companies.&#160; Regulatory assets represent incurred costs that have been deferred because they are probable of future recovery in customer rates.  Regulatory liabilities generally represent amounts collected in rates to recover costs expected to be incurred in the future or amounts collected in excess of costs incurred and are refundable to customers. </span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">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 APS or other regulated entities in the same jurisdiction.&#160; This determination reflects the current political and regulatory climate in Arizona and is subject to change in the future.&#160; If future recovery of costs ceases to be probable, the assets would be written off as a charge in current period earnings.</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">See Note </span><span style="font-size:11.5pt;">3</span><span style="font-family:inherit;font-size:11.5pt;"> for additional information.</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-weight:bold;">Electric Revenues</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;</span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">We derive electric revenues primarily from sales of electricity to our regulated Native Load customers. Revenues related to the sale of electricity are generally recognized 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.  We obtain customers' meter data on a systematic basis throughout the month, and generally bill customers within a month from when service was provided. Customers are generally required to pay for services within 15 days of when the services are billed. Unbilled revenues are estimated by applying an average revenue/kWh by customer class 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.</span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;</span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On January 1, 2018, we adopted new revenue guidance ASU 2014-09, Revenue from contracts with customers, accordingly our 2018 electric revenues primarily consist of activities that now are classified as revenues from contracts with customers. Our electric revenues generally represent a single performance obligation delivered over time. We have elected to apply the invoice practical expedient and, as such, we recognize revenue based on the amount to which we have a right to invoice for services performed. See Note 2.</span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">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.&#160; In the electricity business, some contracts to purchase electricity are netted against other contracts to sell electricity.  This is called a "book-out" and usually occurs for contracts that have the same terms (quantities, delivery points and delivery periods) and for which </span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">power does not flow.

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.&#160; These agreements have a history of uninterrupted renewal that APS expects to continue.&#160; As a result, APS cannot reasonably estimate the fair value of the asset retirement obligation related to such transmission and distribution assets.

This standard provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance. Since the issuance of the new revenue standard, additional guidance was issued to clarify certain aspects of the new revenue standard, including principal versus agent considerations, identifying performance obligations, and other narrow scope improvements. The new revenue standard, and related amendments, became effective for us on January 1, 2018.  The standard may be adopted using a full retrospective application or a simplified transition method that allows entities to record a cumulative effect adjustment in retained earnings at the date of initial application.</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">We adopted this standard and related amendments on January 1, 2018 using the modified retrospective transition approach. The adoption of the new revenue guidance resulted in expanded disclosures, but otherwise did not have a material impact on our financial statements.

The new guidance requires certain investments in equity securities to be measured at fair value with changes in fair value recognized in net income, and modifies the impairment assessment of certain equity securities.  The new standard was effective for us on January 1, 2018. The standard required modified retrospective application, with the exception of certain aspects of the standard that required prospective </span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">application.  We adopted this standard on January 1, 2018, using primarily a retrospective approach.  Due to regulatory accounting treatment, the adoption of this standard did not have a material impact on our financial statements.

The guidance is intended to eliminate diversity in practice in how entities classify these specific activities between cash flows from operating activities, investing activities and financing activities. The specific activities addressed include debt prepayments and extinguishment costs, proceeds from the settlement of insurance claims, proceeds from corporate-owned life insurance policies, and other activities. The standard also addresses how entities should apply the predominance principle when a transaction includes separately identifiable cash flows.  The new standard was effective for us, and was adopted on January 1, 2018, using a retrospective transition method.  The adoption of this guidance did not have a significant impact on our financial statements, as either our statement of cash flow presentation is consistent with the new prescribed guidance or we do not have significant activities relating to the specific transactions that are addressed by the new standard.</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-weight:bold;">ASU 2016-18, Statement of Cash Flows: Restricted Cash</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">In November 2016, a new accounting standard was issued that clarifies how restricted cash and restricted cash equivalents should be presented on the statement of cash flows.

The new standard is effective for us, and was adopted on January 1, 2018, using a retrospective transition method. The adoption of this guidance did not impact our financial statements, as our holdings and activities designated as restricted cash and restricted cash equivalents at transition and in prior periods are insignificant.</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-weight:bold;">ASU 2017-01, Business Combinations:  Clarifying the Definition of a Business</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">In January 2017, a new accounting standard was issued that clarifies the definition of a business. This standard is intended to assist entities with evaluating whether a transaction should be accounted for as an acquisition (or disposal) of assets or a business. &#160;The definition of a business affects many areas of accounting, including acquisitions, disposals, goodwill, and consolidation.

The presentation changes  require net benefit costs to be disaggregated on the income statement by the various components that comprise these costs. Specifically, only the service cost component is eligible for presentation as an operating income item, and all other cost components are now presented as non-operating items. This presentation change was applied retrospectively. Furthermore, the new standard allows only the service cost component to be eligible for capitalization. The change in capitalization requirements was applied prospectively. The new guidance was effective for us on January 1, 2018.</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">We adopted this new accounting standard on January 1, 2018. As a result of adopting this standard we have presented the non-service cost components of net benefits costs in other income instead of operating income.  Prior year non-service cost components have also been reclassified to conform to this new presentation.  We elected to apply the practical expedient guidance.  As such, prior period costs have been estimated based on amounts previously disclosed in our pension and other postretirement benefit plan notes.  The changes impacting capitalization have been adopted prospectively.  As such, upon adoption, we are no longer capitalizing a portion of the non-service cost components of net benefit costs.</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"> In 2018 the non-service credit components are a reduction to total benefit costs.

Amounts eligible for reclassification must relate to the effects from the Tax Act remaining in accumulated other comprehensive income. The new guidance also requires expanded disclosures. This guidance is effective for us on January 1, 2019 with early application permitted. The guidance should be applied either in the period of adoption or retrospectively to each period in which the effect of the Tax Act was recognized.</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">We early adopted this guidance in the quarter ended March 31, 2018, and we have elected to reclassify the income tax effects of the Tax Act related to other comprehensive income to retained earnings.

This new standard supersedes the existing lease accounting model, and modifies both lessee and lessor accounting. The new standard requires a lessee to reflect most operating lease arrangements on the balance sheet by recording a right-of-use asset and a lease liability that is initially measured at the present value of lease payments. Among other changes, the new standard also modifies the definition of a lease, and requires expanded lease disclosures. Since the issuance of the new lease standard, additional lease related guidance has been issued relating to land easements and how entities may elect to account for these arrangements at transition, among other items.  The new lease standard and related amendments were effective for us on January 1, 2019, with early application permitted. The standard must be adopted using a modified retrospective approach with a cumulative-effect adjustment to the opening balance of retained earnings determined at either the date of adoption, or the earliest period presented in the financial statements.  The standard includes various optional practical expedients provided to facilitate transition.</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">We adopted this standard, and related amendments, on January 1, 2019.  We elected the transition method that allows us to apply the guidance on the date of adoption, January 1, 2019, and will not retrospectively adjust prior periods.  We also elected certain transition practical expedients that allow us to not reassess (a) whether any expired or existing contracts are or contain leases, (b) the lease classification for any expired or existing leases and (c) initial direct costs for any existing leases.  These practical expedients apply to leases that commenced prior to January 1, 2019.

Arizona Revised Statute &#167;40-246 requires the ACC to hold a hearing regarding any complaint alleging that a public service corporation is in violation of any commission order or that the rates being charged are not just and reasonable if the complaint is signed by at least </span><span style="font-family:inherit;font-size:11.5pt;"><span>twenty-five</span></span><span style="font-family:inherit;font-size:11.5pt;"> customers of the public </span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">service corporation.

On February 13, 2018, the complainant filed an amended Complaint alleging that the rates and charges in the 2017 Rate Case Decision are not just and reasonable.&#160; The complainant requested that the ACC hold a hearing on the amended Complaint to determine if the average bill impact on residential customers of the rates and charges approved in the 2017 Rate Case Decision is greater than 4.54% (the average annual bill impact for a typical APS residential customer estimated by APS,) and, if so, what effect the alleged greater bill impact has on APS's revenues and the overall reasonableness and justness of APS's rates and charges, in order to determine if there is sufficient evidence to warrant a full-scale rate hearing.&#160; The ACC held a hearing on this matter beginning in September 2018 and the hearing was concluded on October 1, 2018.   Post-hearing briefing was concluded on December 14, 2018.  APS expects a recommended opinion and order from the judge within the first quarter of 2019.

APS&#8217;s budget request included additional funding to process the high volume of residential rooftop solar interconnection requests and also requested a permanent waiver of the residential distributed energy requirement for 2017 contained in the RES rules.  On April 7, 2017, APS filed an amended 2017 RES Implementation Plan and updated budget request which included the revenue neutral transfer of specific revenue requirements into base rates in accordance with the 2017 Settlement Agreement.&#160; On August 15, 2017, the ACC approved the 2017 RES Implementation Plan.</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On June 30, 2017, APS filed its 2018 RES Implementation Plan and proposed a budget of approximately </span><span style="font-family:inherit;font-size:11.5pt;"><span>$90 million</span></span><span style="font-family:inherit;font-size:11.5pt;">.&#160; APS&#8217;s budget request supports existing approved projects and commitments and includes the anticipated transfer of specific revenue requirements into base rates in accordance with the 2017 Settlement Agreement and also requests a permanent waiver of the residential distributed energy requirement for 2018 contained in the RES rules.  APS's 2018 RES budget request is lower than the 2017 RES budget due in part to a certain portion of the RES being collected by APS in base rates rather than through the RES adjustor. </span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On November 20, 2017, APS filed an updated 2018 RES budget to include budget adjustments for APS Solar Communities (formerly known as AZ Sun II), which was approved as part of the 2017 Rate Case Decision.

The ACC approved APS&#8217;s 2015 DSM budget on November 25, 2015.  In its decision, the ACC also ruled that verified energy savings from APS's resource savings projects could be counted toward compliance with the EES; however, the ACC ruled that APS was not allowed to count savings from systems savings projects toward determination of the achievement of performance incentives, nor may APS include savings from conservation voltage reduction in the calculation of its LFCR mechanism.</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On June 1, 2016, APS filed its 2017 DSM Plan, in which APS proposed programs and measures that specifically focus on reducing peak demand, shifting load to off-peak periods and educating customers about strategies to manage their energy and demand.&#160; The requested budget in the 2017 DSM Plan was </span><span style="font-family:inherit;font-size:11.5pt;"><span>$62.6 million</span></span><span style="font-family:inherit;font-size:11.5pt;">.

However, on a quarterly basis, there is a difference between the timing and amount of the income tax benefit and the reduction in revenues refunded through the TEAM related to the lower federal income tax rate. The amount of the benefit of the lower federal income tax rate is based on quarterly pre-tax results, while the reduction in revenues from the prior year due to lower customer rates through the TEAM is based on a per kWh sales credit which follows our seasonal kWh sales pattern and is not impacted by earnings of the Company.</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On August 13, 2018, APS filed a second request with the ACC to return an additional </span><span style="font-family:inherit;font-size:11.5pt;"><span>$86.5 million</span></span><span style="font-family:inherit;font-size:11.5pt;"> in tax savings to customers.

As a result of the ACC&#8217;s action, effective with APS&#8217;s 2017 Rate Case Decision, the net metering tariff that governs payments for energy exported to the grid from residential rooftop solar systems was replaced by a more formula-driven approach that utilizes inputs from historical wholesale solar power until an avoided cost methodology </span><span style="font-family:inherit;font-size:11pt;">is developed by the ACC</span><span style="font-family:inherit;font-size:11.5pt;">.</span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">As amended, the decision provides that payments by utilities for energy exported to the grid from DG solar facilities will be determined using a RCP methodology, a method that is based on the </span><span style="font-family:inherit;font-size:11pt;">most recent five-year rolling average </span><span style="font-family:inherit;font-size:11.5pt;">price that APS pays for utility-scale solar projects, while a forecasted avoided cost methodology is being developed.&#160; The price established by this RCP method will be updated annually (between general retail rate cases) but will not be decreased by more than </span><span style="font-family:inherit;font-size:11.5pt;"><span>10%</span></span><span style="font-family:inherit;font-size:11.5pt;"> per year. Once the avoided cost methodology is developed, the ACC will determine in APS's subsequent rate cases which method (or a combination of methods) is appropriate to determine the actual price to be paid by APS for exported distributed energy.</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">In addition, the ACC made the following determinations:</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman; font-size:10pt;"><tr><td style="width:48px;"/><td/></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:11.5pt;padding-left:24px;"><span style="font-family:inherit;font-size:11.5pt;">&#8226;</span></div></td><td style="vertical-align:top;"><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">Customers who have interconnected a DG system or submitted an application for interconnection for DG systems prior to September 1, 2017, the date new rates were effective based on APS's 2017 Rate Case Decision, will be grandfathered for a period of </span><span style="font-family:inherit;font-size:11.5pt;"><span>20</span></span><span style="font-family:inherit;font-size:11.5pt;"> years from the date the customer&#8217;s interconnection application was accepted by the utility;</span></div></td></tr></table><div style="line-height:120%;text-align:left;padding-left:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman; font-size:10pt;"><tr><td style="width:48px;"/><td/></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:11.5pt;padding-left:24px;"><span style="font-family:inherit;font-size:11.5pt;">&#8226;</span></div></td><td style="vertical-align:top;"><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">Customers with DG solar systems are to be considered a separate class of customers for ratemaking purposes; and</span></div></td></tr></table><div style="line-height:120%;text-align:left;padding-left:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman; font-size:10pt;"><tr><td style="width:48px;"/><td/></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:11.5pt;padding-left:24px;"><span style="font-family:inherit;font-size:11.5pt;">&#8226;</span></div></td><td style="vertical-align:top;"><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">Once an export price is set for APS, no netting or banking of retail credits will be available for new DG customers, and the then-applicable export price will be guaranteed for new customers for a period of </span><span style="font-family:inherit;font-size:11.5pt;"><span>10</span></span><span style="font-family:inherit;font-size:11.5pt;"> years. </span></div></td></tr></table><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">This decision of the ACC addresses policy determinations only.

The subpoenas requested information concerning marketing and advertising expenditures, charitable donations, lobbying expenses, contributions to 501(c)(3) and (c)(4) nonprofits and political contributions.  The return date for the production of information was set as September 15, 2016. The subpoenas also sought testimony from Company personnel having knowledge of the material, including the Chief Executive Officer. </span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On September 9, 2016, APS filed with the ACC a motion to quash the subpoenas or, alternatively to stay APS's obligations to comply with the subpoenas and decline to decide APS's motion pending court proceedings. Contemporaneously with the filing of this motion, APS and Pinnacle West filed a complaint for special action and declaratory judgment in the Superior Court of Arizona for Maricopa County, seeking a declaratory judgment that Commissioner Burns&#8217; subpoenas are contrary to law.  On September 15, 2016, APS produced all non-confidential and responsive documents and offered to produce any remaining responsive documents that are confidential after an appropriate confidentiality agreement is signed.  </span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On February 7, 2017, Commissioner Burns opened a new ACC docket and indicated that its purpose is to study and rectify problems with transparency and disclosure regarding financial contributions from regulated monopolies or other stakeholders who may appear before the ACC that may directly or indirectly benefit an ACC Commissioner, a candidate for ACC Commissioner, or key ACC Staff.&#160; As part of this docket, Commissioner Burns set March 24, 2017 as a deadline for the production of all information previously requested through the subpoenas. Neither APS nor Pinnacle West produced the information requested and instead objected to the subpoena.  On March 10, 2017, Commissioner Burns filed suit against APS and Pinnacle West in the Superior Court of Arizona for Maricopa County in an effort to enforce his subpoenas.  On March 30, 2017, APS filed a motion to dismiss Commissioner Burns' suit against APS and Pinnacle West.   In response to the motion to dismiss, the court stayed the suit and ordered Commissioner Burns to file a motion to compel the production of the information sought by the subpoenas with the ACC.  On June 20, 2017, the ACC denied the motion to compel.   </span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On August 4, 2017, Commissioner Burns amended his complaint to add all of the ACC Commissioners and the ACC itself as defendants.  All defendants moved to dismiss the amended complaint.  On February 15, 2018, the Superior Court dismissed Commissioner Burns&#8217; amended complaint. On March 6, 2018, Commissioner Burns filed an objection to the proposed final order from the Superior Court and a motion to further amend his complaint.  The Superior Court permitted Commissioner Burns to amend his complaint to add a claim regarding his attempted investigation into whether his fellow commissioners should have been disqualified from voting on APS&#8217;s 2017 rate case. Commissioner Burns filed his second amended complaint, and all defendants filed responses opposing the second amended complaint and requested that it be dismissed.  Oral argument occurred in November 2018 regarding the motion to dismiss.  On December 18, 2018, the trial court granted the defendants&#8217; motions to dismiss and entered final judgment on January 18, 2019.  On February 13, 2019, Commissioner Burns filed a notice of appeal.  APS and Pinnacle West cannot predict the outcome of this matter. </span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;padding-bottom:13px;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-weight:bold;">Renewable Energy Ballot Initiative</span></div><div style="line-height:120%;padding-bottom:13px;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On February 20, 2018, a renewable energy advocacy organization filed with the Arizona Secretary of State a ballot initiative for an Arizona constitutional amendment requiring Arizona public service corporations to provide at least </span><span style="font-family:inherit;font-size:11.5pt;"><span>50%</span></span><span style="font-family:inherit;font-size:11.5pt;"> of their annual retail sales of electricity from renewable sources by 2030.

The Energy Modernization Plan includes replacing the current RES standard with a new standard called the CREST, which incorporates the proposals in the Energy Modernization Plan.  On February 22, 2018, the ACC Staff filed a Notice of Inquiry to further examine the matter. As a part of this proposal, the ACC voted in March 2018 to direct utilities to develop a comprehensive biomass generation plan to be included in each utility&#8217;s RES Implementation Plan. On July 5, 2018, Commissioner Tobin&#8217;s office issued a set of draft CREST rules for the ACC&#8217;s consideration.</span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;&#160;&#160;&#160;</span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">In August 2018, the ACC directed ACC Staff to open a new rulemaking docket which will address a wide range of energy issues, including the Energy Modernization Plan proposals.&#160; The rulemaking will consider possible modifications to existing ACC rules, such as the Renewable Energy Standard, Electric and Gas Energy Efficiency Standards, Net Metering, Resource Planning, and the Biennial Transmission Assessment, as well as the development of new rules regarding forest bioenergy, electric vehicles, interconnection of distributed generation, baseload security, blockchain technology and other technological developments, retail competition, and other energy-related topics.&#160; Workshops on these energy issues are scheduled to be held throughout 2019.

On December 23, 2014, the ACC approved rate adjustments resulting in a revenue increase of </span><span style="font-family:inherit;font-size:11.5pt;"><span>$57.1 million</span></span><span style="font-family:inherit;font-size:11.5pt;"> on an annual basis.&#160; This included the deferral for future recovery of all non-fuel operating costs for the acquired SCE interest in Four Corners, net of the non-fuel operating costs savings </span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">resulting from the closure of Units 1-3 from the date of closing of the purchase through its inclusion in rates.&#160; The 2012 Settlement Agreement also provided for deferral for future recovery of all unrecovered costs incurred in connection with the closure of Units 1-3.&#160; The deferral balance related to the acquisition of SCE&#8217;s interest in Units 4 and 5 and the closure of Units 1-3 was </span><span style="font-family:inherit;font-size:11.5pt;"><span>$48 million</span></span><span style="font-family:inherit;font-size:11.5pt;"> as of </span><span style="font-family:inherit;font-size:11.5pt;">December&#160;31, 2018</span><span style="font-family:inherit;font-size:11.5pt;"> and is being amortized in rates over a total of  </span><span style="font-family:inherit;font-size:11.5pt;"><span>10</span></span><span style="font-family:inherit;font-size:11.5pt;"> years.

On December 22, 2015, APS and SCE agreed to terminate the Transmission Termination Agreement and allow for the Transmission Agreement to expire according to its terms, which includes settling obligations in accordance with the terms of the Transmission Agreement.  APS established a regulatory asset of </span><span style="font-family:inherit;font-size:11.5pt;"><span>$12 million</span></span><span style="font-family:inherit;font-size:11.5pt;"> in 2015 in connection with the payment required under the terms of the Transmission Agreement.  On July 1, 2016, FERC issued an order denying APS&#8217;s request to recover the regulatory asset through its FERC-jurisdictional rates.&#160; APS and SCE completed the termination of the Transmission Agreement on July 6, 2016.  APS made the required payment to SCE and wrote-off the </span><span style="font-family:inherit;font-size:11.5pt;"><span>$12 million</span></span><span style="font-family:inherit;font-size:11.5pt;"> regulatory asset and charged operating revenues to reflect the effects of this order in the second quarter of 2016. &#160;On July 29, 2016, APS filed a request for rehearing with FERC.  In its order denying recovery, FERC also referred to its enforcement division a question of whether the agreement between APS and SCE relating to the settlement of obligations under the Transmission Agreement was a jurisdictional contract that should have been filed with FERC.  On October 5, 2017, FERC issued an order denying APS's request for rehearing.  FERC also upheld its prior determination that the agreement relating to the settlement was a jurisdictional contract and should have been filed with FERC.  APS cannot predict whether or if the enforcement division will take any action.  APS filed an appeal of FERC's July 1, 2016 and October 5, 2017 orders with the United States Court of Appeals for the Ninth Circuit on December 4, 2017.

On April 14, 2015, the ACC approved APS's plan to retire Unit 2, without expressing any view on the future recoverability of APS's remaining investment in the Unit.

Pursuant to the 2017 Settlement Agreement described above, APS will be allowed continued recovery of the net book value of the unit and the unit&#8217;s decommissioning and other retirement-related costs (</span><span style="font-family:inherit;font-size:11.5pt;"><span>$89 million</span></span><span style="font-family:inherit;font-size:11.5pt;"> as of </span><span style="font-family:inherit;font-size:11.5pt;">December&#160;31, 2018</span><span style="font-family:inherit;font-size:11.5pt;">), in addition to a return on its investment.  In accordance with GAAP, in the third quarter of 2014, Unit 2&#8217;s remaining net book value was reclassified from property, plant and equipment to a regulatory asset.  The 2017 Settlement Agreement also shortened the depreciation lives of Cholla Units 1 and 3 to 2026.  </span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;font-size:11pt;"><span style="font-family:inherit;font-size:11pt;font-weight:bold;">Navajo Plant</span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">The co-owners of the Navajo Plant and the Navajo Nation agreed that the Navajo Plant will remain in operation until December 2019 under the existing plant lease.  The co-owners and the Navajo Nation executed a lease extension on November 29, 2017 that will allow for decommissioning activities to begin after the plant ceases operations in December 2019.  Various stakeholders including regulators, tribal representatives, the plant's coal supplier and the U.S. Department of the Interior have been meeting to determine if an alternate solution can be reached that would permit continued operation of the plant beyond 2019.  Although we cannot predict whether any alternate plans will be found that would be acceptable to all of the stakeholders and feasible to implement, we believe it is probable that the current owners of the Navajo Plant will cease operations in December 2019.</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;&#160;</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On February 14, 2017, the ACC opened a docket titled "ACC Investigation Concerning the Future of the Navajo Generating Station" with the stated goal of engaging stakeholders and negotiating a sustainable pathway for the Navajo Plant to continue operating in some form after December 2019.  APS cannot predict the outcome of this proceeding.</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">APS is currently recovering depreciation and a return on the net book value of its interest in the Navajo Plant over its previously estimated life through 2026.  APS will seek continued recovery in rates for the book value of its remaining investment in the plant (</span><span style="font-family:inherit;font-size:11.5pt;"><span>$88 million</span></span><span style="font-family:inherit;font-size:11.5pt;"> as of </span><span style="font-family:inherit;font-size:11.5pt;">December&#160;31, 2018</span><span style="font-family:inherit;font-size:11.5pt;">) plus a return on the net book value as well as other costs related to retirement and closure, which are still being assessed and may be material.  APS believes it will be allowed recovery of the net book value, in addition to a return on its investment.  In accordance with GAAP, in the second quarter of 2017, APS's remaining net book value of its interest in the Navajo Plant was reclassified from property, plant and equipment to a regulatory asset.  If the ACC does not allow full recovery of the remaining net book value of this interest, all or a portion of the regulatory asset will be written off and APS's net income, cash flows, and financial position will be negatively impacted.</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-weight:bold;">Regulatory Assets and

This legislation made significant changes to the federal income tax laws, including a reduction in the corporate tax rate to </span><span style="font-family:inherit;font-size:11pt;">21%</span><span style="font-family:inherit;font-size:11pt;"> effective January 1, 2018.  As a result of this rate reduction, the Company recognized a </span><span style="font-family:inherit;font-size:11pt;"><span>$1.14 billion</span></span><span style="font-family:inherit;font-size:11pt;"> reduction in its net deferred income tax liabilities as of December 31, 2017. </span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11pt;">In accordance with accounting for regulated companies, the effect of this rate reduction is substantially offset by a net regulatory liability.

The Company will amortize the net regulatory liability in accordance with applicable federal income tax laws, which require the amortization of a majority of the balance over the remaining regulatory life of the related property.  As a result of the modifications made to the annual transmission formula rate during the second quarter, the Company has recorded amortization of FERC jurisdictional net excess deferred tax liabilities, retroactive to January 1, 2018.  The Company continues to work with the ACC on a plan to amortize the remaining net excess deferred tax liabilities subject to its jurisdiction. See Note 3 for more details.</span></div><div style="line-height:120%;text-indent:48px;font-size:11pt;"><span style="font-family:inherit;font-size:11pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11pt;"><span style="font-family:inherit;font-size:11pt;">In August 2018, Treasury proposed regulations that clarify bonus depreciation transition rules under the Tax Act for regulated public utility property placed in service after September 27, 2017 and before January 1, 2018.  During the third quarter the Company recorded deferred tax liabilities of approximately </span><span style="font-family:inherit;font-size:11pt;"><span>$11 million</span></span><span style="font-family:inherit;font-size:11pt;"> and an increase in its net regulatory liability for excess deferred taxes of approximately </span><span style="font-family:inherit;font-size:11pt;"><span>$9 million</span></span><span style="font-family:inherit;font-size:11pt;">, primarily related to bonus depreciation benefits claimed on the Company&#8217;s 2017 tax return as a result of this clarifying guidance. However, the proposed regulations are ambiguous with respect to regulated public utility property placed in service on or after January 1, 2018. On December 20, 2018, the Joint Committee on Taxation (&#8220;JCT&#8221;)  released the general explanation of the Tax Act. The document - commonly referred to as the "Blue Book" - provides a comprehensive technical description of the Tax Act and includes the legislative intent of Congress with respect to the changes made by provisions of the Tax Act. The &#8220;Blue Book&#8221; provides clarification that the intent of the Tax Act was to exclude from the definition of bonus depreciation qualified property any property placed in service by a regulated public utility after December 31, 2017.  In a footnote, the JCT indicated that a technical correction bill may be necessary to reflect this intent.  </span></div><div style="line-height:120%;text-indent:48px;font-size:11pt;"><span style="font-family:inherit;font-size:11pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11pt;"><span style="font-family:inherit;font-size:11pt;">Management recognizes tax positions which it believes are "more likely than not" to be sustained upon examination. In applying this "more likely than not" assessment, the Company is required to consider the technical merits of a position, including legislative intent.  As a result, while no legislation has been passed which clarifies the ambiguities related to bonus depreciation for property placed in service on or after January 1, 2018, the Company currently believes the continued availability of bonus depreciation is not "more likely than not" to be sustained upon examination. As a result, the Company has not recognized any current or deferred tax benefits related to bonus depreciation for property placed in service on or after January 1, 2018.</span></div><div style="line-height:120%;text-indent:48px;font-size:11pt;"><span style="font-family:inherit;font-size:11pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11pt;"><span style="font-family:inherit;font-size:11pt;">For the quarter ending March 31, 2018, the Company early adopted &#160;ASU 2018-02, Income Statement-Reporting Comprehensive Income: Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income and elected to reclassify the income tax effects of the Tax Act on items within accumulated other comprehensive income to retained earnings.

In December 2016, FERC approved a methodology for determining the amount of other postretirement benefit trust assets to transfer into a new trust account to pay for active union employee medical costs.  On January 2, 2018, these funds were moved to the new trust account, which is included in the other special use funds on the Consolidated Balance Sheets.  The Company and the IRS executed a final Closing Agreement on March 2, 2018.   The Company made an informational filing with FERC during February 2018.  It is the Company&#8217;s understanding that completion of these regulatory requirements permits access to approximately </span><span style="font-family:inherit;font-size:11.5pt;"><span>$186

trust assets relative to the benefit obligations.&#160; To achieve this objective, the plan&#8217;s investment policy provides for mixes of investments including long-term fixed income assets and return-generating assets.&#160; The target allocation between return-generating and long-term fixed income assets is defined in the IPS and is a function of the plan&#8217;s funded status.&#160; The

corporations.&#160; Long-term fixed income assets may also include interest rate swaps, and other instruments.</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span

assets are intended to provide a reasonable long-term rate of investment return with a prudent level of volatility.&#160; Return-generating assets are composed of U.S. equities, international equities, and alternative investments.&#160; International equities include investments in both developed and emerging markets.&#160; Alternative investments include investments in real estate, private equity and various other strategies.&#160; The plan may also hold investments in return-generating assets by holding securities in partnerships, common and collective trusts and mutual

equity securities and real estate through the use of mutual funds, partnerships and common and collective trusts.&#160; Equity securities held directly by the plans are valued using quoted active market prices from the published exchange on which the equity security trades, and are classified as Level 1.&#160; U.S. Treasury Futures Contracts are valued using the quoted active market prices from the exchange on which they trade, and are classified as Level 1.  Fixed income securities issued by the U.S. Treasury held directly by the plans are valued using quoted active market prices, and are classified as Level 1.&#160; Fixed income securities issued by corporations, municipalities, and other agencies are primarily valued using quoted inactive market prices, or quoted active market prices for similar securities, or by utilizing calculations which incorporate observable inputs such as yield, maturity and credit quality.&#160; These instruments are classified as Level 2.</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">Mutual funds, partnerships, and common and collective trusts are valued utilizing a net asset value (NAV) concept or its equivalent.

accounting purposes. This generally occurs when a purchased power contract designates a specific power plant from which the buyer purchases substantially all of the output and also meets other required lease accounting criteria.  APS has certain purchased power contracts that contain lease arrangements.

Amounts recovered in the lawsuit and settlement were recorded as adjustments to a regulatory liability and had no impact on the amount of reported net income.  </span><span style="font-family:inherit;font-size:12pt;">In addition, the settlement agreement, as amended, provides APS with a method for submitting claims and getting recovery for costs incurred through December 31, 2019.</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">APS has submitted four claims pursuant to the terms of the August 18, 2014 settlement agreement, for four separate time periods during July 1, 2011 through June 30, 2018. The DOE has approved and paid </span><span style="font-family:inherit;font-size:11.5pt;"><span>$74.2 million</span></span><span style="font-family:inherit;font-size:11.5pt;"> for these claims (APS&#8217;s share is </span><span style="font-family:inherit;font-size:11.5pt;"><span>$21.6 million</span></span><span style="font-family:inherit;font-size:11.5pt;">).   The amounts recovered were primarily recorded as adjustments to a regulatory liability and had no impact on reported net income.  In accordance with the 2017 Rate Case Decision, this regulatory liability is being refunded to customers (see Note 3).  APS's next claim pursuant to the terms of the August 18, 2014 settlement agreement was submitted to the DOE on October 31, 2018 in the amount of </span><span style="font-family:inherit;font-size:11.5pt;"><span>$10.2 million</span></span><span style="font-family:inherit;font-size:11.5pt;"> (APS's share is </span><span style="font-family:inherit;font-size:11.5pt;"><span>$3.0 million</span></span><span style="font-family:inherit;font-size:11.5pt;">).

On September&#160;3, 2003, EPA advised APS that EPA considers APS to be a PRP in the Motorola 52</span><span style="font-family:inherit;font-size:11.5pt;"><sup style="vertical-align:top;line-height:120%;font-size:pt">nd</sup></span><span style="font-family:inherit;font-size:11.5pt;">&#160;Street Superfund Site, Operable Unit 3 ("OU3") in Phoenix, Arizona.&#160; APS has facilities that are within this Superfund site.&#160; APS and Pinnacle West have agreed with EPA to perform certain investigative activities of the APS facilities within OU3.&#160; In addition, on September&#160;23, 2009, APS agreed with EPA and one other PRP to voluntarily assist with the funding and management of the site-wide groundwater remedial investigation and feasibility study ("RI/FS").&#160; Based upon discussions between the OU3 working group parties and EPA, along with the results of recent technical analyses prepared by the OU3 working group to supplement the RI/FS for OU3, APS anticipates finalizing the RI/FS in the fall or winter of 2019.  We estimate that our costs related to this investigation and study will be approximately </span><span style="font-family:inherit;font-size:11.5pt;"><span>$2 million</span></span><span style="font-family:inherit;font-size:11.5pt;">.&#160; 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 expenditures related to this matter cannot be reasonably estimated.</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On August&#160;6, 2013, Roosevelt Irrigation District ("RID") filed a lawsuit in Arizona District Court against APS and </span><span style="font-family:inherit;font-size:11.5pt;"><span>24</span></span><span style="font-family:inherit;font-size:11.5pt;"> other defendants, alleging that RID&#8217;s groundwater wells were contaminated by the release of hazardous substances from facilities owned or operated by the defendants.&#160; The lawsuit also alleges that, under Superfund laws, the defendants are jointly and severally liable to RID.&#160; The allegations against APS arise out of APS&#8217;s current and former ownership of facilities in and around OU3.&#160; As part of a state governmental investigation into groundwater contamination in this area, on January 25, 2015, ADEQ sent a letter to APS seeking information concerning the degree to which, if any, APS&#8217;s current and former ownership of these facilities may have contributed to groundwater contamination in this area.&#160; APS responded to ADEQ on May 4, 2015.  On December 16, 2016, </span><span style="font-family:inherit;font-size:11.5pt;"><span>two</span></span><span style="font-family:inherit;font-size:11.5pt;"> RID environmental and engineering contractors filed an ancillary lawsuit for recovery of costs against APS and the other defendants in the RID litigation.  That same day, another RID service provider filed an additional ancillary CERCLA lawsuit against certain of the defendants in the main RID litigation, but excluded APS and certain other parties as named defendants.  Because the ancillary lawsuits concern past costs allegedly incurred by these RID vendors, which were ruled unrecoverable directly by RID in November of 2016, the additional lawsuits do not increase APS's exposure or risk related to these matters.</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On April 5, 2018, RID and the defendants in that particular litigation executed a settlement agreement, fully resolving RID's CERCLA claims concerning both past and future cost recovery.  APS's share of this settlement was immaterial.  In addition, the </span><span style="font-family:inherit;font-size:11.5pt;">two</span><span style="font-family:inherit;font-size:11.5pt;"> environmental and engineering vendors voluntarily dismissed their lawsuit against APS and the other named defendants without prejudice.  An order to this effect was entered on April 17, 2018.  With this disposition of the case, the vendors may file their lawsuit again in the future.  In addition, APS and certain other parties not named in the remaining RID service provider lawsuit may be brought into the litigation via third-party complaints filed by the current direct defendants.

APS believed that EPA&#8217;s original 2012 final rule&#160;establishing controls constituting BART for Cholla, which would require installation of SCR controls, was unsupported and that EPA had no basis for disapproving Arizona&#8217;s State Implementation Plan ("SIP") and promulgating a FIP that was inconsistent with the state&#8217;s considered BART determinations under the regional haze program.&#160; In September 2014, APS met with EPA to propose a compromise BART strategy, whereby APS would permanently close Cholla Unit 2 and cease burning coal at Units 1 and 3 by the mid-2020s.  (See Note 3 for details related to the resulting regulatory asset.)  APS made the proposal with the understanding that additional emission control equipment is unlikely to be required in the future because retiring and/or converting the units as contemplated in the proposal is more </span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">cost effective than, and will result in increased visibility improvement over, the BART requirements for oxides of nitrogen ("NOx") imposed through EPA's BART FIP.  In early 2017, EPA approved a final rule incorporating APS's compromise proposal, which took effect for Cholla on April 26, 2017.  </span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;</span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-style:italic;font-weight:bold;">Coal Combustion Waste</span><span style="font-family:inherit;font-size:11.5pt;font-weight:bold;">.</span><span style="font-family:inherit;font-size:11.5pt;">  On December 19, 2014, EPA issued its final regulations governing the handling and disposal of CCR, such as fly ash and bottom ash.  The rule regulates CCR as a non-hazardous waste under Subtitle D of the Resource Conservation and Recovery Act ("RCRA") and establishes national minimum criteria for existing and new CCR landfills and surface impoundments and all lateral expansions consisting of location restrictions, design and operating criteria, groundwater monitoring and corrective action, closure requirements and post closure care, and recordkeeping, notification, and internet posting requirements.  The rule generally requires any existing unlined CCR surface impoundment that is contaminating groundwater above a regulated constituent&#8217;s groundwater protection standard to stop receiving CCR and either retrofit or close, and further requires the closure of any CCR landfill or surface impoundment that cannot meet the applicable performance criteria for location restrictions or structural integrity.  Such closure requirements are deemed "forced closure" or "closure for cause" of unlined surface impoundments, and are the subject of recent regulatory and judicial activities described below.</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On December 16, 2016, President Obama signed the Water Infrastructure Improvements for the Nation ("WIIN") Act into law, which contains a number of provisions requiring EPA to modify the self-implementing provisions of the Agency's current CCR rules under Subtitle D.  Such modifications include new EPA authority to directly enforce the CCR rules through the use of administrative orders and providing states, like Arizona, where the Cholla facility is located, the option of developing CCR disposal unit permitting programs, subject to EPA approval.  For facilities in states that do not develop state-specific permitting programs, EPA is required to develop a federal permit program, pending the availability of congressional appropriations.  By contrast, for facilities located within the boundaries of Native American tribal reservations, such as the Navajo Nation, where the Navajo Plant and Four Corners facilities are located, EPA is required to develop a federal permit program regardless of appropriated funds.  </span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">ADEQ has initiated a process to evaluate how to develop a state CCR permitting program that would cover electric generating units ("EGUs"), including Cholla.  While APS has been working with ADEQ on the development of this program, we are unable to predict when Arizona will be able to finalize and secure EPA approval for a state-specific CCR permitting program.  With respect to the Navajo Nation, APS has sought clarification as to when and how EPA would be initiating permit proceedings for facilities on the reservation, including Four Corners.  We are unable to predict at this time when EPA will be issuing CCR management permits for the facilities on the Navajo Nation.  At this time, it remains unclear how the CCR provisions of the WIIN Act will affect APS and its management of CCR.  </span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">Based upon utility industry petitions for EPA to reconsider the RCRA Subtitle D regulations for CCR, which were premised in part on the CCR provisions of the 2016 WIIN Act, on September 13, 2017 EPA agreed to evaluate whether to revise these federal CCR regulations.  On July 17, 2018, EPA finalized a revision to its RCRA Subtitle D regulations for CCR, the "Phase I, Part I" revision to its CCR regulations, deferring for future action a number of other proposed changes contemplated in a March 1, 2018 proposal.  For the final rule issued on July 17, 2018, EPA established nationwide health-based standards for certain constituents of CCR subject to groundwater corrective action and delayed the closure deadlines for certain unlined CCR surface impoundments by 18 months (for example, those disposal units required to undergo forced closure).  These changes to the federal regulations governing CCR disposal are unlikely to have a material impact on APS.  As for those aspects of the March 2018 rulemaking proposal for which EPA has yet to take final action, it remains unclear which specific provisions of the federal CCR rules will ultimately be modified, how they will be modified, or when such modification will occur.  </span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">Pursuant to a June 24, 2016 order by the D.C. Circuit Court of Appeals in the litigation by industry- and environmental-groups challenging EPA&#8217;s CCR regulations, EPA is required to complete a rulemaking proceeding in the near future concerning whether or not boron must be included on the list of groundwater constituents that might trigger corrective action under EPA&#8217;s CCR rules.&#160; Simultaneously with the issuance of EPA's proposed modifications to the federal CCR rules in response to industry petitions, on March 1, 2018, EPA issued a proposed rule seeking comment as to whether or not boron should be included on this list.  EPA is not required to take final action approving the inclusion of boron.&#160; Should EPA take final action adding boron to the list of groundwater constituents that might trigger corrective action, any resulting corrective action measures may increase APS's costs of compliance with the CCR rule at our coal-fired generating facilities.&#160; At this time APS cannot predict the eventual results of this rulemaking proceeding concerning boron.</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On August 21, 2018, the D.C. Circuit Court issued its decision on the merits in this litigation.  The Court upheld the legality of EPA&#8217;s CCR regulations, though it vacated and remanded back to EPA a number of specific provisions, which are to be corrected in accordance with the Court&#8217;s order.  Among the issues affecting APS&#8217;s management of CCR, the D.C. Circuit&#8217;s decision vacated and remanded those provisions of the EPA CCR regulations that allow for the operation of unlined CCR surface impoundments, even where those unlined impoundments have not otherwise violated a regulatory location restriction or groundwater protection standard (i.e., otherwise triggering forced closure).  At this time, it remains unclear how this D.C. Circuit Court decision will affect APS&#8217;s operations or any financial impacts, as EPA has yet to take regulatory action on remand to revise its 2015 CCR regulations consistent with the Court&#8217;s order. </span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">Based on this decision, on December 17, 2018, certain environmental groups filed an emergency motion with the D.C. Circuit to either stay or summarily vacate EPA's July 17, 2018 final rule extending the closure-initiation deadline for certain unlined CCR surface impoundments until October 2020.  In response, EPA filed a motion to remand but not vacate that deadline extension regulation.  We cannot predict the outcome of the D.C. Circuit's consideration of these dueling motions, and whether or how such a ruling would affect APS's operations.  </span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">APS currently disposes of CCR in ash ponds and dry storage areas at Cholla and Four Corners.  APS estimates that its share of incremental costs to comply with the CCR rule for Four Corners is approximately </span><span style="font-family:inherit;font-size:11.5pt;"><span>$22 million</span></span><span style="font-family:inherit;font-size:11.5pt;"> and its share of incremental costs to comply with the CCR rule for Cholla is approximately </span><span style="font-family:inherit;font-size:11.5pt;"><span>$20 million</span></span><span style="font-family:inherit;font-size:11.5pt;">.  The Navajo Plant currently disposes of CCR in a dry landfill storage area.

Additionally, the CCR rule requires ongoing, phased groundwater monitoring.  By October 17, 2017, electric utility companies that own or operate CCR disposal units, such as APS, must have collected sufficient groundwater sampling data to initiate a detection monitoring program.&#160; To the extent that certain threshold constituents are identified through this initial detection monitoring at levels above the CCR rule&#8217;s standards, the rule required the initiation of an assessment monitoring program by April 15, 2018.</span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">APS recently completed the statistical analyses for its CCR disposal units that triggered assessment monitoring.  APS determined that several of its CCR disposal units at Cholla and Four Corners will need to undergo corrective action.  In addition, all such units must cease operating and initiate closure by October of 2020.  APS currently estimates that the additional incremental costs to complete this corrective action and closure work, along with the costs to develop replacement CCR disposal capacity, could be approximately </span><span style="font-family:inherit;font-size:11.5pt;"><span>$5 million</span></span><span style="font-family:inherit;font-size:11.5pt;"> for both Cholla and Four Corners.  APS initiated an assessment of corrective measures on January 14, 2019, and anticipates completing this assessment during the summer of 2019.  During this assessment, APS will gather additional groundwater data, solicit input from the public, host public hearings, and select remedies.  As such, this </span><span style="font-family:inherit;font-size:11.5pt;"><span>$5 million</span></span><span style="font-family:inherit;font-size:11.5pt;"> cost estimate may change based upon APS&#8217;s performance of the CCR rule&#8217;s corrective action assessment process.

On August 3, 2015, EPA finalized carbon pollution standards for EGUs, the "Clean Power Plan".  On October 10, 2017, EPA issued a proposal to repeal the Clean Power Plan and proposed replacement regulations on August 21, 2018.  In addition, judicial challenges to the Clean Power Plan are pending before the D.C. Circuit, though that litigation is currently in abeyance while EPA develops regulatory action to potentially repeal and replace that regulation.  </span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">EPA's pending proposal to regulate carbon emissions from EGUs replaces the Clean Power Plan with standards that are based entirely upon measures that can be implemented to improve the heat rate of steam-electric power plants, specifically coal-fired EGUs.  In contrast with the Clean Power Plan, EPA's proposed "Affordable Clean Energy Rule" would not involve utility-level generation dispatch shifting away from coal-fired generation and toward renewable energy resources and natural gas-fired combined cycle power plants.  In addition, to address the New Source Review ("NSR") implications of power plant upgrades potentially necessary to achieve compliance with the proposed Affordable Clean Energy Rule standards, EPA also proposed to revise EPA's NSR regulations to more readily authorize the implementation of EGU efficiency upgrades.</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">We cannot predict the outcome of EPA's regulatory actions related to the August 2015 carbon pollution standards for EGU's, including any actions related to EPA's repeal proposal for the Clean Power Plan or additional rulemaking actions to approve the EPA's recently proposed Affordable Clean Energy Rule.

NTEC also alleged a shortfall in the Buyer&#8217;s purchases for the initial contract year of approximately </span><span style="font-family:inherit;font-size:11.5pt;"><span>$30 million</span></span><span style="font-family:inherit;font-size:11.5pt;">.  APS&#8217;s share of this amount is approximately </span><span style="font-family:inherit;font-size:11.5pt;"><span>$17 million</span></span><span style="font-family:inherit;font-size:11.5pt;">.  On September 20, 2017, NTEC amended its Demand for Arbitration, removing its request for a declaratory judgment and at such time was only seeking relief for the alleged shortfall in the Buyer's purchases for the initial contract year. </span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On June 29, 2018, the parties settled the dispute for </span><span style="font-family:inherit;font-size:11.5pt;"><span>$45 million</span></span><span style="font-family:inherit;font-size:11.5pt;">, which includes settlement for the initial contract year and the current contract year.

In connection with the settlement, the parties amended the 2016 Coal Supply Agreement, including modifying the provisions that gave rise to this dispute.   (See &#8220;4CA Matter&#8221; below for additional matters agreed to between 4CA and NTEC in the settlement arrangement.)

NTEC had the option to purchase the </span><span style="font-family:inherit;font-size:11.5pt;"><span>7%</span></span><span style="font-family:inherit;font-size:11.5pt;"> interest within a certain timeframe pursuant to an option granted to NTEC.  On December 29, 2015, NTEC provided notice of its intent to exercise the option.  The purchase did not occur during the originally contemplated timeframe.  Concurrent with the settlement of the 2016 Coal Supply Agreement matter described above, NTEC and 4CA agreed to allow for the purchase by NTEC of the </span><span style="font-family:inherit;font-size:11.5pt;"><span>7%</span></span><span style="font-family:inherit;font-size:11.5pt;"> interest, consistent with the option.  On June 29, 2018, 4CA and NTEC entered into an asset purchase agreement providing for the sale to NTEC of 4CA's </span><span style="font-family:inherit;font-size:11.5pt;"><span>7%</span></span><span style="font-family:inherit;font-size:11.5pt;"> interest in Four Corners.  Completion of the sale was subject to the receipt of approval by FERC, which was received on July 2, 2018, and the sale transaction closed on July 3, 2018.  NTEC purchased the </span><span style="font-family:inherit;font-size:11.5pt;"><span>7%</span></span><span style="font-family:inherit;font-size:11.5pt;"> interest at 4CA&#8217;s book value, approximately </span><span style="font-family:inherit;font-size:11.5pt;"><span>$70 million</span></span><span style="font-family:inherit;font-size:11.5pt;">, and will pay 4CA the purchase price over a period of four years pursuant to a secured interest-bearing promissory note.  In connection with the sale, Pinnacle West guaranteed certain obligations that NTEC will have to the other owners of Four Corners, such as NTEC's </span><span style="font-family:inherit;font-size:11.5pt;"><span>7%</span></span><span style="font-family:inherit;font-size:11.5pt;"> share of capital expenditures and operating and maintenance expenses.  Pinnacle West's guarantee is secured by a portion of APS's payments to be owed to NTEC under the 2016 Coal Supply Agreement.</span></div><div style="line-height:120%;padding-bottom:13px;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">The 2016 Coal Supply Agreement contained alternate pricing terms for the </span><span style="font-family:inherit;font-size:11.5pt;"><span>7%</span></span><span style="font-family:inherit;font-size:11.5pt;"> interest in the event NTEC did not purchase the interest.  Until the time that NTEC purchased the </span><span style="font-family:inherit;font-size:11.5pt;"><span>7%</span></span><span style="font-family:inherit;font-size:11.5pt;"> interest, the alternate pricing provisions were applicable to 4CA as the holder of the </span><span style="font-family:inherit;font-size:11.5pt;"><span>7%</span></span><span style="font-family:inherit;font-size:11.5pt;"> interest.  These terms included a formula under which NTEC must make certain payments to 4CA for reimbursement of operations and maintenance costs and a specified rate of return, offset by revenue generated by 4CA&#8217;s power sales.  Such payments are due to 4CA at the end of each calendar year.  A </span><span style="font-family:inherit;font-size:11.5pt;"><span>$10 million</span></span><span style="font-family:inherit;font-size:11.5pt;"> payment was due to 4CA at December 31, 2017, which NTEC satisfied by directing to 4CA a prepayment from APS of a portion of a future mine reclamation obligation.  The balance of the amount under this formula due December 31, 2018 for calendar year 2017 is approximately </span><span style="font-family:inherit;font-size:11.5pt;"><span>$20 million</span></span><span style="font-family:inherit;font-size:11.5pt;">, which was paid to 4CA on December 14, 2018.  The balance of the amount under this formula at December 31, 2018 for calendar year 2018 (up to the date that NTEC purchased the </span><span style="font-family:inherit;font-size:11.5pt;"><span>7%</span></span><span style="font-family:inherit;font-size:11.5pt;"> interest) is approximately </span><span style="font-family:inherit;font-size:11.5pt;"><span>$10 million</span></span><span style="font-family:inherit;font-size:11.5pt;">, which is due to 4CA at December 31, 2019.</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-weight:bold;">Financial Assurances</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">In the normal course of business, we obtain standby letters of credit and surety bonds from financial institutions and other third parties.

In addition, due to the sale of 4CA assets to NTEC in 2018 (see Note 10 for more information on 4CA matters) there was a decrease to the ARO of </span><span style="font-family:inherit;font-size:11.5pt;"><span>$9 million</span></span><span style="font-family:inherit;font-size:11.5pt;">.

These instruments are typically structured as investment companies offering shares or units to multiple investors for the purpose of providing a return. These instruments are similar to mutual funds; however, their NAV is generally not published and publicly available, nor are these instruments traded on an exchange.  Instruments valued using NAV, as a practical expedient are included in our fair value disclosures however, in accordance with GAAP are not classified within the fair value hierarchy levels.</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-weight:bold;">Recurring Fair Value Measurements</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">We apply recurring fair value measurements to cash equivalents, derivative instruments, and investments held in the nuclear decommissioning trust and other special use funds. On an annual basis we apply fair value measurements to plan assets held in our retirement and other benefit plans.&#160; See Note 7 for fair value discussion of plan assets held in our retirement and other benefit plans.</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-style:italic;font-weight:bold;">Cash Equivalents</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">Cash equivalents represent certain investments in money market funds that are valued using quoted prices in active markets.</span></div><div style="line-height:120%;text-align:center;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-style:italic;font-weight:bold;">Risk Management Activities &#8212;

For non-exchange traded commodity contracts, we calculate fair value based on the average of the bid and offer price, discounted to reflect net present value.&#160; We maintain certain valuation adjustments for a number of risks associated with the valuation of future commitments.&#160; These include valuation adjustments for liquidity and credit risks.&#160; The liquidity valuation adjustment represents the cost that would be incurred if all unmatched positions were closed out or hedged.&#160; The credit valuation adjustment represents estimated credit losses on our net exposure to counterparties, taking into account netting agreements, expected default experience for the credit rating of the counterparties and the overall diversification of the portfolio.&#160; We maintain credit policies that management believes minimize overall credit risk.</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">Certain non-exchange traded commodity contracts are valued based on unobservable inputs due to the long-term nature of contracts, characteristics of the product, or the unique location of the transactions.&#160; 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.&#160; We rely primarily on broker quotes to value these instruments.&#160; When our valuations utilize broker quotes, we perform various control procedures to ensure the quote has been developed consistent with fair value accounting guidance.&#160; These controls include assessing the quote for reasonableness by comparison against other broker quotes, reviewing historical price relationships, and assessing market activity.&#160; When broker quotes are not available, the primary valuation technique used to calculate the fair value is the extrapolation of forward pricing curves using observable market data for more liquid delivery points in the same region and actual transactions at more illiquid delivery points.</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">When the unobservable portion is significant to the overall valuation of the transaction, the entire transaction is classified as Level 3.&#160; Our classification of instruments as Level 3 is primarily reflective of the long-term nature of our energy transactions.</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">Our energy risk management committee, consisting of officers and key management personnel, oversees our energy risk management activities to ensure compliance with our stated energy risk management policies.&#160;

Our trustees and escrow agent use pricing services that utilize the valuation methodologies described below to determine fair market value. We have internal control procedures designed to ensure this information is consistent with fair value accounting guidance. These procedures include assessing valuations using an independent pricing source, verifying that pricing can be supported by actual recent market transactions, assessing hierarchy classifications, comparing investment returns with benchmarks, and obtaining and reviewing independent audit reports on the trustees&#8217; and escrow agent's internal operating controls and valuation processes.</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-style:italic;font-weight:bold;">Fixed Income Securities</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">Fixed income securities issued by the U.S. Treasury are valued using quoted active market prices and are typically classified as Level 1.&#160; Fixed income securities issued by corporations, municipalities, and other agencies, including mortgage-backed instruments, are valued using quoted inactive market prices, quoted active market prices for similar securities, or by utilizing calculations which incorporate observable inputs such as yield curves and spreads relative to such yield curves.&#160; These fixed income instruments are classified as Level 2.&#160; Whenever possible, multiple market quotes are obtained which enables a cross-check validation.&#160; A primary price source is identified based on asset type, class, or issue of securities.</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">Fixed income securities may also include short-term investments in certificates of deposit, variable rate notes, time deposit accounts, U.S. Treasury and Agency obligations, U.S. Treasury repurchase agreements, commercial paper, and other short term instruments.

The funds' NAV is primarily derived from the quoted active market prices of the underlying equity securities held by the funds.  We may transact in these commingled funds on a semi-monthly basis at the NAV.&#160; The commingled funds are maintained by a bank and hold investments in accordance with the stated objective of tracking the performance of the S&amp;P 500 Index.&#160; Because the commingled funds' shares are offered to a limited group of investors, they are not considered to be traded in an active market.

Restricted stock unit awards that will be settled in cash are accounted for as liability awards, with compensation cost initially calculated on the date of grant using the Company&#8217;s closing stock price, and remeasured at each balance sheet date. Restricted stock unit awards that will be settled in shares are accounted for as equity awards, with compensation cost calculated using the Company's closing stock price on the date of grant.  Compensation cost is recognized over the requisite service period based on the fair value of the award. </span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">Stock grants are issued to non-officer members of the Board of Directors.  They may elect to receive the stock grant, or to defer receipt until a later date and receive stock units in lieu of the stock grant.&#160; The members of the Board of Directors who elect to defer may elect to receive payment in either </span><span style="font-family:inherit;font-size:11.5pt;"><span>100%</span></span><span style="font-family:inherit;font-size:11.5pt;"> stock,   </span><span style="font-family:inherit;font-size:11.5pt;"><span>100%</span></span><span style="font-family:inherit;font-size:11.5pt;"> cash, or </span><span style="font-family:inherit;font-size:11.5pt;"><span>50%</span></span><span style="font-family:inherit;font-size:11.5pt;"> in cash and </span><span style="font-family:inherit;font-size:11.5pt;"><span>50%</span></span><span style="font-family:inherit;font-size:11.5pt;"> in stock.&#160; Each stock unit is convertible to one share of stock. The stock units accrue dividend rights, equal to the amount of dividends the Directors would have received had they directly owned stock equal to the number of vested restricted stock units or stock units from the date of grant to the date of payment, plus interest compounded quarterly.&#160; The dividends and interest are paid, based on the Director&#8217;s election, in either stock, cash, or </span><span style="font-family:inherit;font-size:11.5pt;"><span>50%</span></span><span style="font-family:inherit;font-size:11.5pt;"> in cash and </span><span style="font-family:inherit;font-size:11.5pt;"><span>50%</span></span><span style="font-family:inherit;font-size:11.5pt;"> in stock.</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-weight:bold;">Performance Share Awards</span></div><div style="line-height:120%;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">Performance share awards are granted to officers and key employees.&#160; The awards contain </span><span style="font-family:inherit;font-size:11.5pt;"><span>two</span></span><span style="font-family:inherit;font-size:11.5pt;"> separate performance criteria that affect the number of shares that may be received if after the end of a </span><span style="font-family:inherit;font-size:11.5pt;"><span>3</span></span><span style="font-family:inherit;font-size:11.5pt;">-year performance period the performance criteria are met.  For the first criteria, the number of shares that will vest is based on non-financial performance metrics (i.e., the metric component). The other criteria is based upon Pinnacle West's total shareholder return ("TSR") in relation to the TSR of other companies in a specified utility index (i.e., the TSR component). The exact number of shares issued will vary from </span><span style="font-family:inherit;font-size:11.5pt;"><span>0%</span></span><span style="font-family:inherit;font-size:11.5pt;"> to </span><span style="font-family:inherit;font-size:11.5pt;"><span>200%</span></span><span style="font-family:inherit;font-size:11.5pt;"> of the target award.&#160; Shares received include dividend rights paid in stock equal to the amount of dividends that recipients would have received had they directly owned stock, equal to the number of vested performance shares from the date of grant to the date of payment plus interest compounded quarterly.  If the award is forfeited or if the performance criteria are not achieved, the employee is not entitled to the dividends on those shares.</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;</span></div>Performance share awards are accounted for as equity awards, with compensation cost based on the fair value of the award on the grant date. Compensation cost relating to the metric component of the award is based on the Company&#8217;s closing stock price on the date of grant, with compensation cost recognized over the requisite service period based on the number of shares expected to vest. Management evaluates the probability of meeting the metric component at each balance sheet date. If the metric component criteria are not ultimately achieved, no compensation cost is recognized relating to the metric component, and any previously recognized compensation cost is reversed.  Compensation cost relating to the TSR component of the award is determined using a Monte Carlo simulation valuation model, with compensation cost recognized ratably over the requisite service period, regardless of the number of shares that actually vest.<span></span>

style="font-family:inherit;font-size:11.5pt;">Derivative financial instruments are used to manage exposure to commodity price and transportation costs of electricity, natural gas, coal, emissions allowances and interest rates.&#160; Risks associated with market volatility are managed by utilizing various physical and financial derivative instruments, including futures, forwards, options and swaps.&#160; As part of our overall risk management program, we may use derivative instruments to hedge purchases and sales of electricity and fuels.&#160; Derivative instruments that meet certain hedge accounting criteria may be designated as cash flow hedges and are used to limit our exposure to cash flow variability on forecasted transactions.&#160; The changes in market value of such instruments have a high correlation to price changes in the hedged transactions.&#160; Derivative instruments are also entered into for economic hedging purposes.&#160; While economic hedges may mitigate exposure to fluctuations in commodity prices, these instruments have not been designated as accounting hedges.&#160; Contracts that have the same terms (quantities, delivery points and delivery periods) and for which power does not flow are netted, which reduces both revenues and fuel and purchased power costs in our Consolidated Statements of Income, but does not impact our financial condition, net income or cash flows.</span></div><div style="line-height:120%;text-align:center;font-size:11.5pt;"><span

derivative instruments, excluding those qualifying for a scope exception, are recorded on the balance sheet as an asset or liability and are measured at fair value.&#160; See Note 13 for a discussion of fair value measurements.&#160; Derivative instruments may qualify for the normal purchases and normal sales scope exception if they require physical delivery and the quantities represent those transacted in the normal course of business.&#160; Derivative instruments qualifying for the normal purchases and sales scope exception are accounted for under the accrual method of accounting and

losses in the event of nonperformance or nonpayment by counterparties and have risk management contracts with many counterparties.  As of </span><span style="font-family:inherit;font-size:11.5pt;">December&#160;31, 2018</span><span style="font-family:inherit;font-size:11.5pt;">, Pinnacle West has no counterparties with positive exposures of greater than 10% of risk management assets.  Our risk management process assesses and monitors the financial exposure of all counterparties.&#160; Despite the fact that the great majority of trading counterparties' debt is rated as investment grade by the credit rating agencies, there is still a possibility that one or more of these counterparties 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.&#160; We maintain credit policies that we believe minimize overall credit risk to within acceptable limits.&#160; 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.&#160; 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.&#160; Valuation adjustments are established representing our estimated credit losses on our overall exposure to counterparties.</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;</span></div><div style="line-height:120%;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">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.&#160; Adequate assurance provisions allow a counterparty with reasonable grounds for uncertainty to demand additional collateral based on subjective events and/or conditions.&#160; 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&#160;&amp;

The new revenue guidance requires entities to recognize revenue when control of the promised good or service is transferred to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. We applied the new guidance using the modified retrospective method applied to contracts which were not completed as of January 1, 2018. The adoption of the new revenue guidance resulted in expanded disclosures but otherwise did not have a material impact on our financial statements. New revenue disclosures required by the standard are included below, and in Note 1.

APS, our wholly-owned subsidiary, is a vertically-integrated electric utility that provides either retail or wholesale electric service to substantially all of the state of Arizona, with the major exceptions of about one-half of the Phoenix metropolitan area, the Tucson metropolitan area and Mohave County in northwestern Arizona.&#160; APS accounts for essentially all of our revenues and earnings, and is expected to continue to do so.&#160; El Dorado is an investment firm.  BCE is a subsidiary that was formed in 2014 that focuses on growth opportunities that leverage the Company's core expertise in the electric energy industry.  BCE is currently pursuing transmission opportunities through a joint venture arrangement.  4CA is a subsidiary that was formed in 2016 as a result of the purchase of El Paso's </span><span style="font-family:inherit;font-size:11.5pt;"><span>7%</span></span><span style="font-family:inherit;font-size:11.5pt;"> interest in Four Corners.

Beginning in the quarter ended March 31, 2018, APS changed the format of presentation of its Consolidated Statements of Income from a utility ratemaking format to a commercial format.  Minor changes were made in the description of certain income statement line items and the amounts presented in the comparable prior period also changed by immaterial amounts due to the change from a utility to a non-utility format and also from the adoption of the new accounting guidance for net periodic pension cost and net periodic postretirement benefit cost.  In addition, the prior year amounts were reclassified to conform to the current year presentation for the other special use funds in the investment and other assets section on the Consolidated Balance Sheets.<span></span>

Revenues related to the sale of electricity are generally recognized 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.  We obtain customers' meter data on a systematic basis throughout the month, and generally bill customers within a month from when service was provided. Customers are generally required to pay for services within 15 days of when the services are billed. Unbilled revenues are estimated by applying an average revenue/kWh by customer class 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.</span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">&#160;</span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">On January 1, 2018, we adopted new revenue guidance ASU 2014-09, Revenue from contracts with customers, accordingly our 2018 electric revenues primarily consist of activities that now are classified as revenues from contracts with customers. Our electric revenues generally represent a single performance obligation delivered over time. We have elected to apply the invoice practical expedient and, as such, we recognize revenue based on the amount to which we have a right to invoice for services performed. See Note 2.</span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">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.&#160; In the electricity business, some contracts to purchase electricity are netted against other contracts to sell electricity.  This is called a "book-out" and usually occurs for contracts that have the same terms (quantities, delivery points and delivery periods) and for which </span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">power does not flow.

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.&#160; These agreements have a history of uninterrupted renewal that APS expects to continue.&#160; As a result, APS cannot reasonably estimate the fair value of the asset retirement obligation related to such transmission and distribution assets.

This standard provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance. Since the issuance of the new revenue standard, additional guidance was issued to clarify certain aspects of the new revenue standard, including principal versus agent considerations, identifying performance obligations, and other narrow scope improvements. The new revenue standard, and related amendments, became effective for us on January 1, 2018.  The standard may be adopted using a full retrospective application or a simplified transition method that allows entities to record a cumulative effect adjustment in retained earnings at the date of initial application.</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">We adopted this standard and related amendments on January 1, 2018 using the modified retrospective transition approach.

The guidance is intended to eliminate diversity in practice in how entities classify these specific activities between cash flows from operating activities, investing activities and financing activities. The specific activities addressed include debt prepayments and extinguishment costs, proceeds from the settlement of insurance claims, proceeds from corporate-owned life insurance policies, and other activities. The standard also addresses how entities should apply the predominance principle when a transaction includes separately identifiable cash flows.  The new standard was effective for us, and was adopted on January 1, 2018, using a retrospective transition method.  The adoption of this guidance did not have a significant impact on our financial statements, as either our statement of cash flow presentation is consistent with the new prescribed guidance or we do not have significant activities relating to the specific transactions that are addressed by the new standard.</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;font-weight:bold;">ASU 2016-18, Statement of Cash Flows: Restricted Cash</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">In November 2016, a new accounting standard was issued that clarifies how restricted cash and restricted cash equivalents should be presented on the statement of cash flows.

The presentation changes  require net benefit costs to be disaggregated on the income statement by the various components that comprise these costs. Specifically, only the service cost component is eligible for presentation as an operating income item, and all other cost components are now presented as non-operating items. This presentation change was applied retrospectively. Furthermore, the new standard allows only the service cost component to be eligible for capitalization. The change in capitalization requirements was applied prospectively. The new guidance was effective for us on January 1, 2018.</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">We adopted this new accounting standard on January 1, 2018. As a result of adopting this standard we have presented the non-service cost components of net benefits costs in other income instead of operating income.  Prior year non-service cost components have also been reclassified to conform to this new presentation.  We elected to apply the practical expedient guidance.  As such, prior period costs have been estimated based on amounts previously disclosed in our pension and other postretirement benefit plan notes.  The changes impacting capitalization have been adopted prospectively.  As such, upon adoption, we are no longer capitalizing a portion of the non-service cost components of net benefit costs.</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"> In 2018 the non-service credit components are a reduction to total benefit costs.

Amounts eligible for reclassification must relate to the effects from the Tax Act remaining in accumulated other comprehensive income. The new guidance also requires expanded disclosures. This guidance is effective for us on January 1, 2019 with early application permitted. The guidance should be applied either in the period of adoption or retrospectively to each period in which the effect of the Tax Act was recognized.</span></div><div style="line-height:120%;text-align:left;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:11.5pt;"><span style="font-family:inherit;font-size:11.5pt;">We early adopted this guidance in the quarter ended March 31, 2018, and we have elected to reclassify the income tax effects of the Tax Act related to other comprehensive income to retained earnings.

This new standard supersedes the existing lease accounting model, and modifies both lessee and lessor accounting. The new standard requires a lessee to reflect most operating lease arrangements on the balance sheet by recording a right-of-use asset and a lease liability that is initially measured at the present value of lease payments. Among other changes, the new standard also modifies the definition of a lease, and requires expanded lease disclosures. Since the issuance of the new lease standard, additional lease related guidance has been issued relating to land easements and how entities may elect to account for these arrangements at transition, among other items.  The new lease standard and related amendments were effective for us on January 1, 2019, with early application permitted. The standard must be adopted using a modified retrospective approach with a cumulative-effect adjustment to the opening balance of retained earnings determined at either the date of adoption, or the earliest period presented in the financial statements.

We elected the transition method that allows us to apply the guidance on the date of adoption, January 1, 2019, and will not retrospectively adjust prior periods.  We also elected certain transition practical expedients that allow us to not reassess (a) whether any expired or existing contracts are or contain leases, (b) the lease classification for any expired or existing leases and (c) initial direct costs for any existing leases.  These practical expedients apply to leases that commenced prior to January 1, 2019.

The amounts presented may be further subdivided to show amounts applicable to plant subcategories (for example, production, transmission, distribution). Includes statements that the amounts represent the utility's share in each joint plant and that it must provide its own financing. Information concerning two or more generating plants on the same site may be combined. States that the utility's share of direct expenses of the joint plants is included in the corresponding operating expenses on its income statement (for example, fuel, maintenance of plant, other operating expense). If the share of direct expenses is charged to purchased power, then disclose the amount so charged and the proportionate amounts charged to specific operating expenses on the records maintained for the joint plants.</p></div>
