EL PASO ELECTRIC COMPANY

NOTES TO FINANCIAL STATEMENTS

(Unaudited)

A. Principles of Preparation

These condensed financial statements should be read in conjunction with the financial statements and notes thereto in the Annual Report of El Paso Electric Company (the "Company") on Form 10-K for the fiscal year ended December 31, 2018 ("2018 Form 10-K"). Capitalized terms used in this report and not defined herein have the meaning ascribed to such terms in the 2018 Form 10-K. In the opinion of the Company’s management, the accompanying financial statements contain all adjustments necessary to present fairly the financial position of the Company at September 30, 2019 and December 31, 2018; the results of its operations and comprehensive operations for the three, nine and twelve months ended September 30, 2019 and 2018; changes in common stock equity for the three and nine months ended September 30, 2019 and 2018; and its cash flows for the nine months ended September 30, 2019 and 2018. The results of operations, comprehensive operations and the changes in common stock equity for the three and nine months ended September 30, 2019 and 2018, and the cash flows for the nine months ended September 30, 2019 and 2018, are not necessarily indicative of the results to be expected for the full calendar year.

Pursuant to the rules and regulations of the United States ("U.S.") Securities and Exchange Commission ("SEC"), certain financial information has been condensed and certain footnote disclosures have been omitted. Such information and disclosures are normally included in financial statements prepared in accordance with U.S. Generally Accepted Accounting Principles ("GAAP").

Use of Estimates. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The Company evaluates its estimates on an on-going basis, including those related to depreciation, unbilled revenue, income taxes, fuel costs, pension and other post-retirement obligations and asset retirement obligations. Actual results could differ from those estimates.

Operating Revenues. The Company accrues revenues for services rendered, including unbilled electric service revenues. The Company recognizes revenue associated with contracts with customers when performance obligations under the terms of the contract with the customer are satisfied. Revenue is measured as the amount of consideration the Company receives in exchange for transferring goods or providing services to the customer. Taxes collected concurrently with revenue producing activities are excluded from revenue. Unbilled revenues are recorded for estimated amounts of energy delivered in the period following the customer's last billing cycle to the end of the reporting period. Unbilled revenues are estimated based on monthly generation volumes and by applying an average revenue/kilowatt-hour ("kWh") to the number of estimated kWhs delivered but not billed. Accounts receivable included accrued unbilled revenues of $33.3 million at September 30, 2019 and $21.6 million at December 31, 2018.

The Company’s Texas retail customers are billed under base rates and a fixed fuel factor approved by the Public Utility Commission of Texas ("PUCT"). The Company’s New Mexico retail customers are billed under base rates and a fuel adjustment clause that is adjusted monthly, as approved by the New Mexico Public Regulation Commission ("NMPRC"). The Company's Federal Energy Regulatory Commission ("FERC") sales for resale customers are billed under formula base rates and fuel factors and a fuel adjustment clause that is adjusted monthly. The Company’s recovery of fuel and purchased power expenses is subject to periodic reconciliations of actual fuel and purchased power expenses incurred to actual fuel revenues collected. The difference between fuel and purchased power expenses incurred and fuel revenues charged to customers is reflected as over/under-collection of fuel revenues, which is included in regulatory liabilities/assets - current in the balance sheets. See Part I, Item 1, Financial Statements, Note D of Notes to Financial Statements for further discussion.

Leases. The Company determines if an arrangement contains a lease and the classification of that lease at inception. Operating lease right-of-use (“ROU”) assets represent the Company’s right to use an underlying asset for the lease term and operating lease liabilities represent the obligation to make payments under the lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the estimated present value of the minimum lease payments over the lease term. In determining lease terms, the Company considers any options to extend or terminate the lease that are reasonably certain of being exercised. As the Company’s leases do not include an implicit rate, the Company uses an estimated incremental borrowing rate, at lease commencement, to determine the present value of the future lease payments. In calculating the incremental borrowing rate, the Company takes into consideration recent debt issuances and other data for instruments with similar characteristics. The Company’s lease agreements do not contain residual value guarantees or restrictive covenants. For leases with lease and non-lease components, the Company has elected to account for the consideration as a single lease component. The Company has also elected not to record leases with a term of 12 months or less on the balance sheets. The operating lease ROU assets are included as part of electric plant in service and lease liabilities are included as part of current and non-current liabilities in the Company’s balance sheets.

Depreciation. The Company routinely evaluates the depreciable service lives, cost of removal and salvage values of its property, plant and equipment. Depreciation is provided on a straight-line basis over the estimated remaining lives of the assets (ranging in average from 5 to 48 years). When property subject to composite depreciation is retired or otherwise disposed of in the normal course of business, its cost together with the cost of removal, less salvage is charged to accumulated depreciation. For other property dispositions, the applicable cost and accumulated depreciation is removed from the balance sheet accounts and a gain or loss is recognized.

New Accounting Standards Adopted

In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-02, Leases (Topic 842), to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and requiring qualitative and quantitative disclosures on leasing agreements. ASU 2016-02 maintains a distinction between finance leases and operating leases similar to the distinction under previous lease guidance for capital leases and operating leases. Effective January 1, 2019, the Company adopted ASU 2016-02 using the modified retrospective method, applying the transition provisions to the beginning of the period of adoption rather than to the earliest comparative period presented, which continues to be reported in accordance with previous lease guidance, Accounting Standards Codification Topic 840. The Company adopted the package of practical expedients, which does not require the Company to reassess: (i) whether an arrangement contained a lease, (ii) lease classification for any expired or existing leases, and (iii) initial direct costs for any expired or existing leases. The Company also adopted the practical expedient related to land easements, which allowed carry forward accounting treatment for existing land easements. The most significant impact of adopting ASU 2016-02, as of January 1, 2019, was the recording of approximately $6.3 million of operating lease liabilities and related ROU assets with no cumulative effect adjustment to retained earnings. The Company anticipates the ongoing impact of the new standard to be immaterial to net income and cash flows. See Part I, Item 1, Financial Statements, Note I of Notes to Financial Statements for further discussion.

In February 2018, the FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220), as a result of concerns raised due to the federal law commonly referred to as the Tax Cuts and Jobs Act of 2017 ("TCJA"). More specifically, because the remeasurement of deferred taxes due to the change in the federal corporate income tax rate is required to be included in income from continuing operations, the tax effects of items within accumulated other comprehensive income ("AOCI") (referred to as stranded tax effects) do not reflect the appropriate tax rate. ASU 2018-02 allows companies an election to reclassify stranded taxes from AOCI to retained earnings. The amount of the reclassification would be the difference between the historical federal corporate income tax rate of 35% and the newly enacted 21% federal corporate income tax rate, which approximates $7.2 million. The provisions of ASU 2018-02 are effective for fiscal years and interim periods within that reporting period beginning after December 15, 2018. The Company adopted ASU 2018-02 on January 1, 2019, and has elected to not reclassify stranded taxes from AOCI to retained earnings.

New Accounting Standards to be Adopted in the Future

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326). ASU 2016-13 changes how companies measure and recognize credit impairment for many financial assets. The new expected credit loss model will require companies to immediately recognize an estimate of credit losses expected to occur over the remaining life of the financial assets that are in the scope of the standard. ASU 2016-13 will be required for reporting periods beginning after December 15, 2019. ASU 2016-13 will be applied in a modified retrospective approach through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is implemented. The Company is currently in the process of evaluating the impact of the new standard, which includes continuing to monitor activities of the FASB, including the impact of ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments and ASU 2019-05, Financial Instruments - Credit Losses (Topic 326): Targeted Transition Relief.

D. Regulation

General

The rates and services of the Company are regulated by incorporated municipalities in Texas, the PUCT, the NMPRC and the FERC. Municipal orders, ordinances and other agreements regarding rates and services adopted by Texas municipalities are subject to review and approval by the PUCT. The FERC has jurisdiction over the Company's wholesale (sales for resale - full requirement customer) transactions, transmission service and compliance with federally-mandated reliability standards. The decisions of the PUCT, the NMPRC and the FERC are subject to judicial review.

On June 1, 2019, the Company entered into an Agreement and Plan of Merger (the "Merger Agreement"), by and among the Company, Sun Jupiter Holdings LLC, a Delaware limited liability company ("Parent"), and Sun Merger Sub Inc., a Texas corporation and wholly owned subsidiary of Parent ("Merger Sub"). Pursuant to the Merger Agreement, on and subject to the terms and conditions set forth therein, Merger Sub will merge with and into the Company (the "Merger"), with the Company continuing as the surviving corporation in the Merger and becoming a wholly owned subsidiary of Parent. Parent and Merger Sub are affiliates of Infrastructure Investments Fund, an investment vehicle advised by J.P. Morgan Investment Management Inc. ("IIF"). Among other things, the Company, Parent and Merger Sub are required to obtain certain regulatory approvals of the proposed Merger as discussed further in Part I, Item 1, Financial Statements, Note N of the Notes to the Financial Statements.

On August 13, 2019, the Company, Parent and IIF US Holding 2 LP, an affiliate of IIF, as applicable, filed (1) the joint report and application for regulatory approvals with the PUCT requesting approval of the Merger pursuant to the Texas Public Utility Regulatory Act ("PURA"), (2) the joint application for regulatory approvals with the NMPRC requesting approval of the Merger pursuant to the New Mexico Public Utility Act ("NMPUA") and NMPRC Rule 450, (3) the joint application requesting approval of the Merger with the FERC under Section 203 of the Federal Power Act and (4) the joint application for regulatory approval for the indirect transfer of the Company’s Nuclear Regulatory Commission ("NRC") licenses to Parent from the NRC under the Atomic Energy Act of 1954. In addition, on August 13, 2019, the Company and Parent sought the authorization of the Federal Communications Commission ("FCC") to assign or transfer control of the Company’s FCC licenses.

On August 16, 2019, the Company and Parent filed the notification and report form with the Antitrust Division of the Department of Justice and the Federal Trade Commission ("FTC") under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the "HSR Act"), as amended, and the rules and regulations promulgated thereunder. On September 3, 2019, the Company and Parent received notice from the FTC granting early termination of the waiting period under the HSR Act. 

Texas Regulatory Matters

2017 Texas Retail Rate Case Filing. On February 13, 2017, the Company filed with the City of El Paso, other municipalities incorporated in the Company's Texas service territory and the PUCT in the 2017 Texas Retail Rate Case, a request for an increase in non-fuel base revenues. On November 2, 2017, the Company filed the Joint Motion to Implement Uncontested Stipulation and Agreement with the Administrative Law Judges ("ALJ") for the 2017 Texas Retail Rate Case.

On December 18, 2017, the PUCT issued the PUCT Final Order in Docket No. 46831 ("2017 PUCT Final Order"), which provides, among other things, for the following: (i) an annual non-fuel base rate increase of $14.5 million; (ii) a return on equity of 9.65%; (iii) all new plant in service as filed in the Company's rate filing package was prudent and used and useful and therefore is included in rate base; (iv) recovery of the costs of decommissioning Four Corners Generating Station in the amount of $5.5 million over a seven year period beginning August 1, 2017; (v) the Company to recover reasonable rate case expenses of approximately $3.4 million through a separate surcharge over a three year period; and (vi) a requirement that the Company file a refund tariff if the federal statutory income tax rate, as it relates to the Company, is decreased before the Company files its next rate case. The 2017 PUCT Final Order also established baseline revenue requirements for recovery of future transmission and distribution investment costs (for which the Company could seek recovery after January 1, 2019) and includes a minimum monthly bill of $30.00 for new residential customers with distributed generation, such as private rooftop solar. Additionally, the 2017 PUCT Final Order allowed for the annual recovery of $2.1 million of nuclear decommissioning funding and establishes annual depreciation expense that is approximately $1.9 million lower than the annual amount requested by the Company in its initial filing. Finally, the 2017 PUCT Final Order allowed for the Company to recover revenues associated with the relate back of rates to consumption on and after July 18, 2017, through a separate surcharge.

New base rates, including additional surcharges associated with rate case expenses and the relate back of rates to consumption on and after July 18, 2017, through December 31, 2017, were implemented in January 2018. The surcharge for the relate back of

rates expired on January 9, 2019, with a net over-recovery balance of $0.5 million that was addressed in the fuel reconciliation proceeding filed on September 27, 2019, which was assigned PUCT Docket No. 50058.

For financial reporting purposes, the Company deferred any recognition of the Company's request in its 2017 Texas Retail Rate Case until it received the 2017 PUCT Final Order on December 18, 2017. Accordingly, it reported in the fourth quarter of 2017 the cumulative effect of the 2017 PUCT Final Order, which related back to July 18, 2017.

The 2017 PUCT Final Order required the Company to file a refund tariff if the federal statutory income tax rate, as it relates to the Company, was decreased before the Company files its next general rate case. Following the enactment of the TCJA on December 22, 2017, and in compliance with the 2017 PUCT Final Order, on March 1, 2018, the Company filed with the PUCT and each of its Texas municipalities a proposed refund tariff designed to reduce base charges for Texas customers equivalent to the expected annual decrease of $22.7 million in federal income tax expense resulting from the TCJA changes and an additional refund of $4.3 million for the amortization of a regulatory liability related to the reduced tax expense for the months of January through March of 2018. This filing was assigned PUCT Docket No. 48124. On March 27, 2018, the PUCT approved the Company's proposed refund tariff on an interim basis, subject to refund or surcharge, for customer billing effective April 1, 2018. Each of the Company's municipalities also implemented the Company's proposed tax credits on an interim basis effective April 1, 2018. The refund is reflected in rates over a period of one year beginning April 1, 2018, and will be updated annually until new base rates are implemented pursuant to the Company's next Texas rate case filing. The PUCT issued an order on December 10, 2018, approving the proposed refund tariff. On February 22, 2019, the Company filed with the PUCT and each of its Texas municipalities an application to modify the tax refund tariff to remove the portion of the base rate credit associated with the $4.3 million of regulatory liability amortization, which expired March 31, 2019. The filing was assigned PUCT Docket No. 49251 and approved by final order on June 27, 2019.

Texas Energy Efficiency Cost Recovery Factor ("EECRF"). On May 1, 2017, the Company filed its annual application with the PUCT, which was assigned PUCT Docket No. 47125, to establish its EECRF for 2018. In addition to projected energy efficiency costs for 2018 and a reconciliation of collections to prior year actual costs, the Company requested approval of an incentive bonus for the 2016 energy efficiency program results in accordance with PUCT rules. Interim rates were approved effective January 1, 2018. The Company, the PUCT Staff and the City of El Paso reached an agreement that includes an incentive bonus of $0.8 million. The agreement was filed on January 25, 2018, and was approved by the PUCT on February 15, 2018.

On May 1, 2018, the Company filed its annual application with the PUCT, which was assigned PUCT Docket No. 48332, to establish its EECRF for 2019. In addition to projected energy efficiency costs for 2019 and a reconciliation of collections to actual costs for the prior year, the Company requested approval of a $1.0 million incentive bonus for the 2017 energy efficiency program results in accordance with PUCT rules. Instead of convening a live hearing on the merits of this case, the parties agreed to enter into the record the pre-filed testimony of the parties and certain other exhibits and then file briefs on the contested issues. The ALJ issued a proposal for decision on November 15, 2018, including the Company's fully requested incentive bonus. On January 17, 2019, the PUCT issued a final order approving a modified bonus amount of $0.9 million.

On May 1, 2019, the Company filed its annual application with the PUCT, which was assigned PUCT Docket No. 49496, to establish its EECRF for 2020. In addition to projected energy efficiency costs for 2020 and a reconciliation of collections to actual costs for the prior year, the Company requested approval of a $0.8 million incentive bonus for the 2018 energy efficiency program results in accordance with PUCT rules. On July 1, 2019, the Company requested, and received approval for, a suspension of the procedural schedule in order to pursue settlement of the case. On July 12, 2019, the Company informed the ALJ in the case that all parties had agreed in principle on terms for settlement. On August 14, 2019, the Company filed an unopposed settlement agreement and proposed order which resolved all issues in the proceeding. The case was remanded on August 16, 2019, to the PUCT for a final order approving the settlement agreement and the Company's EECRF rates. On October 11, 2019, the PUCT indicated that certain rate case expenses in the amount of approximately $15 thousand should be removed from the revenue requirement and postponed final consideration until its November 14, 2019, Open Meeting to allow for the filing of additional information reflecting the removal of that expense.

Fuel and Purchased Power Costs. The Company's actual fuel costs, including purchased power energy costs, net of the cost of off-system sales and related shared margins, are recovered from customers through a fixed fuel factor. The PUCT has adopted a fuel cost recovery rule ("Texas Fuel Rule") that allows the Company to seek periodic adjustments to its fixed fuel factor. The Company can seek to revise its fixed fuel factor based upon the approved formula at least four months after its last revision except in the month of December. The Texas Fuel Rule requires the Company to request to refund fuel costs in any month when the over-recovery balance exceeds a threshold material amount and it expects fuel costs to continue to be materially over-recovered. The Texas Fuel Rule also permits the Company to seek to surcharge fuel under-recoveries in any month the balance exceeds a threshold

material amount and it expects fuel cost recovery to continue to be materially under-recovered. Fuel over- and under-recoveries are considered material when they exceed 4% of the previous twelve months' fuel costs. All such fuel revenue and expense activities are subject to periodic final review by the PUCT in periodic fuel reconciliation proceedings.

On October 13, 2017, the Company filed a request with the PUCT, which was assigned PUCT Docket No. 47692, to decrease the Texas fixed fuel factor by approximately 19% to reflect decreased fuel expenses primarily related to a decrease in the price of natural gas used to generate power. The decrease in the Texas fixed fuel factor became effective beginning with the November 2017 billing month.

On April 13, 2018, the Company filed a request with the PUCT, which was assigned PUCT Docket No. 48264, to decrease the Texas fixed fuel factor by approximately 29% to reflect decreased fuel expenses primarily related to a decrease in the price of natural gas used to generate power. On April 25, 2018, the Company's proposed fuel factors were approved on an interim basis effective for the first billing cycle of the May 2018 billing month. The revised factor was approved by the PUCT and the docket closed on May 22, 2018.

On October 15, 2018, the Company filed a request with the PUCT, which was assigned PUCT Docket No. 48781, to decrease the Texas fixed fuel factor by approximately 6.99% to reflect decreased fuel expenses primarily related to a decrease in the price of natural gas used to generate power. On October 25, 2018, the Company's fixed fuel factor was approved on an interim basis effective for the first billing cycle of the November 2018 billing month. The revised factor was approved by the PUCT and the docket closed on November 19, 2018.

On April 29, 2019, the Company filed a petition with the PUCT, which was assigned PUCT Docket No. 49482, requesting authority to implement, beginning on June 1, 2019, a four-month, interim fuel refund of $19.4 million in fuel cost over-recoveries, including interest, for the period from April 2016 through March 2019. On May 30, 2019, the Company's fuel refund credit was approved on an interim basis. The Company implemented the fuel refund in customer bills on June 1, 2019. On September 27, 2019, the PUCT issued a final order approving the fuel refund credits. The fuel refund was completed on September 30, 2019, with a total fuel refund of $20.1 million, including interest, returned to Texas customers.

On September 13, 2019, the Company filed a request with the PUCT, which was assigned PUCT Docket No. 49960, to decrease the Texas fixed fuel factor by approximately 12.2% to reflect decreased fuel expenses primarily related to a decrease in the price of natural gas used to generate power. On September 25, 2019, the Company's fixed fuel factor was approved by the PUCT on an interim basis effective for the first billing cycle of the October 2019 billing month. The Texas fixed fuel factor was determined to be final on October 15, 2019, and will continue until changed by the PUCT. As of September 30, 2019, the Company had a net fuel over-recovery balance of approximately $14.1 million in Texas.

Fuel Reconciliation Proceeding. On September 27, 2019, the Company filed an application with the PUCT, which was assigned PUCT Docket No. 50058, to reconcile $363.0 million of Texas fuel and purchased power expenses incurred during the period of April 1, 2016, through March 31, 2019. The Company cannot predict the outcome of this filing at this time. The April 1, 2019, through September 30, 2019, Texas jurisdictional fuel and purchased power costs subject to a future prudence review total approximately $36.7 million.

Community Solar. On June 8, 2015, the Company filed a petition with the PUCT to initiate a community solar program that includes the construction and ownership of a three-megawatt ("MW") solar photovoltaic system located at Montana Power Station ("MPS"). Participation is on a voluntary basis, and customers contract for a set capacity (kW) amount and receive all energy produced. This case was assigned PUCT Docket No. 44800. The Company filed a settlement agreement among all parties on July 1, 2016, approving the program, and the PUCT approved the settlement agreement and program on September 1, 2016. On April 19, 2017, the Company announced that the entire three-MW program was fully subscribed by approximately 1,500 Texas customers. The Community Solar facility began commercial operation on May 31, 2017.

On March 20, 2018, the Company filed a petition with the PUCT and each of its Texas municipalities to expand its community solar program in Texas to include two-MW of solar powered generation from the ten-MW solar photovoltaic facility located at Newman Power Station ("Newman") and to reduce rates under the community solar tariff. The case before the PUCT was assigned PUCT Docket No. 48181, and a hearing was held on December 4, 2018. The ALJ issued a proposal for decision on March 19, 2019, that approved the project as proposed by the Company. On May 9, 2019, the PUCT approved the Company's request to expand the program utilizing the two-MW of solar powered generation available from Newman. New subscriptions for the expanded program were accepted beginning in June 2019, and new rates for all existing and new customers were implemented in customer bills beginning July 1, 2019. As of June 30, 2019, the expanded program was fully subscribed.

Transmission Cost Recovery Factor. On January 25, 2019, the Company filed an application with the PUCT to establish its Transmission Cost Recovery Factor ("TCRF"), which was assigned PUCT Docket No. 49148 (the "2019 TCRF rate filing"). The 2019 TCRF rate filing is designed to recover a requested $8.2 million of Texas jurisdictional transmission revenue requirement that is not currently being recovered in the Company's Texas base rates for transmission-related investments placed in service from October 1, 2016, through September 30, 2018, net of retirements. Pursuant to the procedural order issued on February 20, 2019, the Company’s TCRF rate was approved on an interim basis effective July 30, 2019, subject to any refund or surcharge to the extent the PUCT’s final order establishes a TCRF rate that differs from the interim rate. On September 12, 2019, the Company filed an unopposed settlement agreement and proposed order for a TCRF revenue requirement of $7.5 million with a provision for recovery of revenue relating-back to the interim effective date of July 30, 2019. Such relate back revenue through September 30, 2019, is expected to approximate $1.4 million. The ALJ remanded the proceeding to the PUCT for consideration of a final order. The Company cannot predict the outcome of this pending matter at this time.

Distribution Cost Recovery Factor. On March 28, 2019, the Company filed an application with the PUCT and each of its Texas municipalities to establish its Distribution Cost Recovery Factor (“DCRF”), which was assigned PUCT Docket No. 49395 (the “2019 DCRF rate filing”). The 2019 DCRF rate filing is designed to recover a requested $7.9 million of Texas jurisdictional distribution revenue requirement that is not currently being recovered in the Company’s Texas base rates for distribution-related investments placed in service from October 1, 2016, through December 31, 2018, net of retirements. On August 13, 2019, the Company filed an unopposed settlement agreement and proposed order which resolved all issues in the proceeding and approved a DCRF revenue requirement of $7.8 million. On September 27, 2019, the PUCT issued a final order reflecting the settlement agreement, and the Company's DCRF rates became effective in customer bills beginning October 1, 2019.

Other Required Approvals. The Company has obtained other required approvals for tariffs and other approvals required by the PURA and the PUCT.

New Mexico Regulatory Matters

Future New Mexico Rate Case Filing. The Company was required to file its next New Mexico base rate case no later than July 31, 2019. On July 10, 2019, the NMRPC issued an order approving a joint request by the Company, NMPRC Staff, and the New Mexico Attorney General to delay filing of the Company's next base rate case until after the conclusion of a proceeding addressing the Merger. The NMPRC order requires the Company to file its next rate case application within three months of the conclusion of the proceeding addressing the Merger in New Mexico. The Company cannot predict the outcome of this filing at this time. See Part I, Item 1, Financial Statements, Note N of Notes to Financial Statements for further discussion.

New Mexico Order Commencing Review of the Effects of the TCJA on Regulated New Mexico Utilities. On January 24, 2018, the NMPRC initiated a proceeding in Case No. 18-00016-UT on the impact of the TCJA on New Mexico regulated utilities. On April 4, 2018, the NMPRC issued an order requiring the Company to file a proposed interim rate rider to adjust the Company's New Mexico base revenues in amounts equivalent to the Company's reduced income tax expense for New Mexico customers resulting from the TCJA, to be implemented on or before May 1, 2018. The NMPRC order further requires that the Company record and track a regulatory liability for the excess accumulated deferred income taxes created by the change in the federal corporate income tax rate, consistent with the effective date of the TCJA, and subject to amortization determined by the NMPRC in the Company's next general rate case. The Company recorded such a regulatory liability during the quarter ended December 31, 2017. On April 16, 2018, after consultation with the New Mexico Attorney General pursuant to the NMPRC order, the Company filed an interim rate rider with the NMPRC with a proposed effective date of May 1, 2018. The annualized credits expected to be refunded to New Mexico customers approximate $4.9 million. The Company implemented the interim rate rider in customer bills beginning May 1, 2018 pursuant to the NMPRC order.

On September 5, 2018, the NMPRC issued an order in Case No. 17-00255-UT involving Southwestern Public Service Company’s ("SPS’s") request to change rates in which the NMPRC directed SPS to refund the difference in corporate tax rate from January 1, 2018, through the effective date of new rates. SPS appealed the NMPRC order to the New Mexico Supreme Court in Southwestern Public Service Co. v. NMPRC, No. S-1-SC-37248 ("SPS Appeal No. 1"), challenging the refund as prohibited retroactive ratemaking among other reasons. The New Mexico Supreme Court issued a partial and interim stay of the rates on September 26, 2018. On September 12, 2018, the NMPRC in Case No. 18-00016-UT issued an Order Regarding the Disposition of Tax Savings Under the Federal Tax Cuts and Jobs Act of 2017, which put public utilities on notice that all revenue collected through general rates for the purpose of payment of federal income taxes is and will continue to be subject to possible refund upon a subsequent determination to be made in the appropriate pending or future NMPRC adjudicatory hearing. On October 11, 2018, SPS filed a Notice of Appeal of that NMPRC order to the New Mexico Supreme Court in Southwestern Public Service Co. v. NMPRC, No. S-1-SC-37308 ("SPS Appeal No. 2"). On February 15, 2019, the NMPRC and SPS filed a joint motion for remand

and stipulated dismissal of SPS appeals of NMPRC orders with the New Mexico Supreme Court, which among other things, reflected agreements between the NMPRC and SPS, which in part provide that the NMPRC will replace the order in Case No. 17-00255-UT with a new order that eliminates the retroactive TCJA refund and that SPS will request dismissal of SPS Appeals No. 1 and No. 2. On February 28, 2019, the New Mexico Supreme Court remanded SPS Appeal No. 1 back to the NMPRC and dismissed the appeal. On March 6, 2019, the NMPRC issued a revised final order on remand in Case No. 17-00255-UT that, in part, eliminated the retroactive TCJA refund.

Fuel and Purchased Power Costs. Pursuant to NMPRC Rule 550, fuel and purchased power costs, net of the cost of off-system sales and related shared margins, are reconciled to actual costs on a monthly basis and recovered or refunded to customers the second succeeding month through the Fuel and Purchased Power Cost Adjustment Clause ("FPPCAC"). The Company must file an application for continued use of its FPPCAC no more than four years from the date its last FPPCAC was continued. As required, the Company filed a request to continue use of its FPPCAC with the NMPRC on January 5, 2018, which was assigned Case No. 18-00006-UT. The NMPRC issued a final order in the case on February 13, 2019, which authorized the Company to continue use of its FPPCAC without change and approved the Company's reconciliation of its fuel and purchased power costs for the period January 1, 2015, through December 31, 2016. New Mexico jurisdictional costs subject to prudence review are costs from January 1, 2017, through September 30, 2019, that total approximately $107.3 million. At September 30, 2019, the Company had a net fuel under-recovery balance of approximately $1.4 million related to the FPPCAC in New Mexico.

New Mexico Renewable Portfolio Standard. Effective January 1, 2018, pursuant to the final order in NMPRC Case No. 17-00090-UT, the Renewable Portfolio Standard ("RPS") costs for New Mexico are recovered through a separate RPS Cost Rider and not through the FPPCAC. At September 30, 2019, the Company had a net fuel over-recovery balance related to the RPS Cost Rider of approximately $1.6 million. The RPS Cost Rider is updated in an annual NMPRC filing, including a reconciliation of the prior year’s RPS costs and RPS Cost Rider revenue. On October 1, 2019, the Company filed its required application with the NMPRC for its 2019 Annual Renewable Plan in Case No. 19-0099-UT and for adjustment of its RPS Cost Rider for reconciliation of 2018 costs and revenues and to recover RPS costs for 2020. The application requests approvals of the Company's plan to meet requirements of the Renewable Energy Act, as amended in 2019. The Company cannot predict the outcome of this filing at this time.

5-MW Holloman Air Force Base ("HAFB") Facility Certificate of Convenience and Necessity ("CCN"). On October 7, 2015, in Case No. 15-00185-UT, the NMPRC issued a final order approving a CCN for a five-MW solar power generation facility located on HAFB in the Company's service territory in New Mexico. The Company and HAFB negotiated a retail contract, which includes a power sales agreement for the facility, to replace the existing load retention agreement that was approved by NMPRC final order issued October 5, 2016, in Case No. 16-00224-UT. The solar generation facility began commercial operation on October 18, 2018.

New Mexico Efficient Use of Energy Recovery Factor. On July 1, 2016, the Company filed its annual application with the NMPRC requesting approval of its 2017 Energy Efficiency and Load Management Plan and to establish the Efficient Use of Energy Recovery Factor ("EUERF") for 2017. In addition to projected energy efficiency costs for 2017, the Company requested approval of a $0.4 million incentive for 2017 energy efficiency programs in accordance with NMPRC rules. This application was assigned Case No. 16-00185-UT. On February 22, 2017, the NMPRC issued a final order approving the Company’s 2017 Energy Efficiency and Load Management Plan. The Company’s EUERF was approved and effective in customer bills beginning on March 1, 2017. NMPRC rules authorize continuation of the energy efficiency programs and incentive approved in Case No. 16-00185-UT through 2018. The Company recorded approved incentives in operating revenues of $0.3 million and $0.7 million in 2018 and 2017, respectively, related to its 2015 through 2017 Energy Efficiency and Load Management Plans. During the three months ended September 30, 2019, the Company recorded an incentive in operating revenues of $0.4 million related to its 2018 Energy Efficiency Programs.

On July 2, 2018, the Company filed its required application with the NMPRC for approval of its 2019-2021 Energy Efficiency and Load Management Plan and EUERF. The application was assigned Case No. 18-00116-UT. On March 6, 2019, the NMPRC issued a final order approving: (i) the Company's 2019-2021 Energy Efficiency and Load Management Plan, with minor program modifications; (ii) the base incentive of 7.1% of program expenditures, or approximately $0.4 million annually for 2019-2021; and (iii) the continuation of the Company's EUERF.

Community Solar. On April 24, 2018, the Company filed an application with the NMPRC to initiate a community solar program in New Mexico to include construction and ownership of a two-MW solar photovoltaic system located in Doña Ana County near the City of Las Cruces. Customer participation would have been on a voluntary basis, and customers would have contracted for a set capacity (kW) amount and would have received all energy produced by their subscribed capacity. The application was assigned Case No. 18-00099-UT and was dismissed without prejudice on October 31, 2018. The NMPRC set aside its

October 31, 2018, order dismissing the application without prejudice, and on December 19, 2018, the NMPRC issued an Order Requiring El Paso Electric Company to Conduct Request for Proposals and to Amend Application; Order Extending Statutory Period and Appointing Hearing Examiner that would have required the Company to amend its initially-filed application on or before February 15, 2019. However, on January 10, 2019, the NMPRC with three new Commissioners reconsidered its December 19, 2018 order and dismissed the Community Solar application without prejudice. The case is now closed.

Integrated Resource Plan ("IRP"). On September 17, 2018, the Company filed its IRP with the NMPRC for the period 2018-2037 ("2018 IRP") in Case No. 18-00293-UT as required by regulation and the Joint Stipulation in NMPRC Case No. 15-00241-UT, which was the Company's prior integrated resource plan filing. The triennial filing requires a public advisory process as part of the development of the plan to identify a cost-effective portfolio of resources. The filed plan is subject to written public comments filed with the NMPRC to which the Company responded on October 29, 2018. NMPRC Staff filed a written report on November 16, 2018, recommending that the NMPRC return the 2018 IRP to the Company with instructions for re-filing to correct 12 deficiencies identified by the NMPRC Staff report. On December 5, 2018, the NMPRC issued an Order Partially Accepting Integrated Resource Plan; Order Requiring Refiling for Deficiencies. Pursuant to that order, on January 3, 2019, the Company filed an amended 2018 IRP. On January 10, 2019, in light of a pending motion for reconsideration, the NMPRC ordered its Staff to provide additional information and respond to issues raised regarding the filed 2018 IRP. On March 15, 2019, NMPRC Staff filed the additional response and recommended that the Company correct one deficiency identified. On September 18, 2019, the NMPRC issued a variance from the IRP rule on commission review, acceptance and action, and closed the docket.

Issuance of Long-Term Debt, Securities Financing, and Guarantee of Debt. On October 7, 2015, the Company received approval in NMPRC Case No. 15-00280-UT to guarantee the issuance of up to $65.0 million of long-term debt by the Rio Grande Resources Trust II ("RGRT") to finance future purchases of nuclear fuel and to refinance existing nuclear fuel debt obligations, which remains effective. Under this authorization, on June 28, 2018, the RGRT issued $65.0 million in aggregate principal amount of 4.07% Senior Guaranteed Notes due August 15, 2025. On October 4, 2017, the Company received additional approval in NMPRC Case No. 17-00217-UT to amend and extend the Company's Revolving Credit Facility ("RCF"), issue up to $350.0 million in long-term debt and to redeem and refinance the $63.5 million 2009 Series A 7.25% Pollution Control Bonds ("PCBs") and the $37.1 million 2009 Series B 7.25% PCBs. The NMPRC approval to issue $350.0 million in long-term debt supersedes its prior approval. Under this authorization, on June 28, 2018, the Company issued $125.0 million in aggregate principal amount of the Company's 4.22% Senior Notes due August 15, 2028. Additionally, on September 13, 2018, the Company and the Bank of New York Mellon Trust Company, N.A., as trustee of the RGRT, entered into a $350.0 million third amended and restated credit agreement.

On January 30, 2019, the Company submitted an application with the NMPRC seeking approval to issue shares of common stock, including the reissuance of treasury shares, in an amount up to $200.0 million in one or more transactions. The application was assigned Case No. 19-00033-UT, and the NMPRC issued a final order approving the Company's request on March 27, 2019. On February 1, 2019 and April 1, 2019, the Company purchased in lieu of redemption all $63.5 million aggregate principal amount of 2009 Series A 7.25% PCBs and $37.1 million aggregate principal amount of 2009 Series B 7.25% PCBs, respectively. The bonds were purchased utilizing funds borrowed under the RCF. On May 22, 2019, the Company reoffered and sold $63.5 million aggregate principal amount of 2009 Series A 7.25% PCBs and $37.1 million aggregate principal amount of 2009 Series B 7.25% PCBs with a fixed interest rate of 3.60% per annum until the bonds mature on February 1, 2040 and April 1, 2040, respectively. The bonds are subject to optional redemption at a redemption price of par on or after June 1, 2029. See Part I, Item 1, Financial Statements, Note M of Notes to Financial Statements for further discussion.

Amendments to the New Mexico Renewable Energy Act (“REA”). The REA requires electric utilities to meet an RPS of twenty percent of its total retail sales to New Mexico customers by 2020, reduced for sales to  qualifying large non-governmental customers whose costs are capped under the REA (“Large Customer Adjustment”) and subject to a reasonable cost threshold (“RCT”) established by the NMPRC and currently set by the NMPRC at 3 percent of customers’ bills.  Effective June 14, 2019, the New Mexico Energy Transition Act amends the REA (the “Amended REA”) to, among other amendments: (i) increase the RPS to forty percent by 2025, fifty percent by 2030, and eighty percent by 2040; (ii) impose a zero-carbon standard by 2045; (iii) eliminate the Large Customer Adjustment; (iv) set a statutory RCT; and (v) provide cost recovery for certain undepreciated investments and decommissioning costs (i.e., coal-fired generation) associated with generation required by the NMPRC to be discontinued and replaced with lower or zero-carbon generation. In administering the eighty percent RPS and zero-carbon standards, the Amended REA requires by Commission to consider certain factors, including safety, reliability and rate impact to customers.  On October 10, 2019, the NMPRC initiated a rulemaking proceeding to implement the Amended REA in Case No. 19-00296-UT.  The Company is currently evaluating the impact that the Amended REA may have on its operations. Further, the Company has not determined the costs associated with complying with the Amended REA including potential fines that could be associated with non-compliance.

Federal Regulatory Matters

Inquiry Regarding the Effect of the TCJA on Commission-Jurisdictional Rates and Order to Show Cause. On March 15, 2018, the FERC issued two show cause orders under Section 206 of the Federal Power Act and Rule 209(a) of the FERC’s Rules of Practice and Procedure, directing 48 individual public utilities with stated transmission rates or transmission formula rates with a fixed line item of 35% for the federal income tax component to, within 60 days of the date of the orders, either (1) propose revisions to their transmission rates under their open access transmission tariffs or transmission owner tariffs on file with the FERC, or (2) show cause why they should not be required to do so ("Show Cause Proceeding"). The Company was included in the list of public utilities impacted by the FERC orders. On May 14, 2018, the Company submitted its response, as required by the FERC order, which demonstrated that the reduced annual income tax does not cause the Company's total transmission revenues to become excessive and therefore no rate reduction was justified. Instead, the Company stated in its response that it will prepare for a future filing in which it will seek approval for revised Open Access Transmission Tariff ("OATT") rates that would include the recovery of an increased total transmission revenue requirement from OATT customers based on current circumstances and appropriate forward-looking adjustments. On November 15, 2018, FERC issued an order finding that the Company had demonstrated that no rate reduction was justified and terminating the Show Cause Proceeding. The Company expects to file its request for approval to revise OATT rates in the fourth quarter of 2019 or early 2020.

Notice of Proposed Rulemaking on Public Utility Transmission Changes to Address Accumulated Deferred Income Taxes. On November 15, 2018, the FERC issued a Notice of Proposed Rulemaking ("NOPR") that proposes to direct public utilities with transmission OATT rates, a transmission owner tariff or a rate schedule to determine the amount of excess or deficient accumulated deferred income taxes caused by the TCJA’s reduction to the federal corporate income tax rate and return or recover this amount to or from customers. The NOPR has been assigned FERC Docket No. RM19-5-000. The Company is currently evaluating the impact of this proposed rulemaking.

Issuance of Long-Term Debt, Securities Financing, and Guarantee of Debt. On October 31, 2017, the FERC issued an order in Docket No. ES17-54-000 approving the Company’s filing to (i) amend and extend the RCF; (ii) issue up to $350.0 million in long-term debt; (iii) guarantee the issuance of up to $65.0 million of long-term debt by the RGRT; and (iv) redeem, refinance, and/or replace the $63.5 million 2009 Series A 7.25% PCBs and the $37.1 million 2009 Series B 7.25% PCBs. The order also approved the Company's request to continue to utilize the Company's existing RCF with the ability to amend and extend at a future date. The authorization was effective from November 15, 2017, through November 14, 2019, and superseded prior FERC approvals. Under this authorization, on June 28, 2018, the Company issued $125.0 million in aggregate principal amount of the Company's 4.22% Senior Notes due August 15, 2028, and the RGRT issued $65.0 million in aggregate principal amount of its 4.07% Senior Guaranteed Notes due August 15, 2025. Also, on September 13, 2018, the Company and the Bank of New York Mellon Trust Company, N.A., as trustee of the RGRT, entered into a $350.0 million third amended and restated credit agreement. On February 1, 2019 and April 1, 2019, the Company purchased in lieu of redemption all $63.5 million aggregate principal amount of 2009 Series A 7.25% PCBs and $37.1 million aggregate principal amount of 2009 Series B 7.25% PCBs, respectively. The bonds were purchased utilizing funds borrowed under the RCF.

On January 30, 2019, the Company submitted an application with the FERC seeking approval to issue shares of common stock, including the reissuance of treasury shares, in an amount up to $200.0 million in one or more transactions. Included in the FERC application, the Company also requested various debt-related authorizations: approval to utilize the existing RCF for short-term borrowings not to exceed $400.0 million at any one time; to issue up to $225.0 million in new long-term debt; and to remarket the $63.5 million 2009 Series A 7.25% PCBs and the $37.1 million 2009 Series B 7.25% PCBs in the form of replacement bonds or senior notes of equivalent value, not to exceed $100.6 million. On April 18, 2019, the FERC issued an order authorizing the issuances through April 18, 2021. On May 22, 2019, the Company reoffered and sold $63.5 million aggregate principal amount of 2009 Series A 7.25% PCBs and $37.1 million aggregate principal amount of 2009 Series B 7.25% PCBs with a fixed interest rate of 3.60% per annum until the bonds mature on February 1, 2040 and April 1, 2040, respectively. The bonds are subject to optional redemption at a redemption price of par on or after June 1, 2029. See Part I, Item 1, Financial Statements, Note M of Notes to Financial Statements for further discussion.

E. Palo Verde

Spent Fuel and Waste Disposal. Pursuant to the Nuclear Waste Policy Act of 1982, as amended in 1987, the U.S. Department of Energy ("DOE") is legally obligated to accept and dispose of all spent nuclear fuel and other high-level radioactive waste generated by all domestic power reactors by 1998. The DOE's obligations are reflected in a contract for Disposal of Spent Nuclear Fuel and/or High Level Radioactive Waste with each nuclear power plant. The DOE failed to begin accepting spent nuclear fuel by 1998. Pursuant to the terms of the August 18, 2014 settlement agreement, and as amended with the DOE, Arizona Public Service Company ("APS") files annual claims for the period July 1 of the then-previous year to June 30 of the then-current year on behalf of itself and those utilities that share in power and energy entitlements, and bear certain allocated costs, with respect to Palo Verde Generating Station ("Palo Verde") pursuant to the Arizona Nuclear Power Project Participation Agreement dated August 23, 1973, as amended ("ANPP Participation Agreement"). The settlement agreement, as amended, provides APS with a method for submitting claims and receiving recovery for costs incurred through December 31, 2016, which has been extended to December 31, 2019.

On October 31, 2019, APS filed a $16.0 million claim for the period July 1, 2018 through June 30, 2019. The Company's share of this claim is approximately $2.5 million. This claim is pending DOE review. The majority of the reimbursement received by the Company is expected to be credited to customers through the applicable fuel adjustment clauses.

G. Income Taxes

The Company files income tax returns in the U.S. federal jurisdiction and in the states of Texas, New Mexico and Arizona. The Company is no longer subject to tax examination by the taxing authorities in the federal, Texas, Arizona and New Mexico jurisdictions for years prior to 2014.

For the three months ended September 30, 2019 and 2018, the Company’s effective tax rate was 23.0% and 23.7%, respectively. For the nine months ended September 30, 2019 and 2018, the Company's effective tax rate was 22.8% and 23.4%, respectively. For the twelve months ended September 30, 2019 and 2018, the Company's effective tax rate was 23.1% and 22.8%, respectively. The federal statutory tax rate is 21% in 2019 and 2018, and 35% in 2017. The Company's effective tax rate for all periods in 2019 and 2018 differ from the federal statutory tax rate due to state income taxes, capital gains in the decommissioning trusts which are taxed at the federal rate of 20%, the tax benefit of stock incentive plans, the allowance for equity funds used during construction ("AEFUDC") and other permanent differences.

H. Commitments, Contingencies and Uncertainties

For a full discussion of commitments and contingencies, see Part II, Item 8, Financial Statements and Supplementary Data, Note L of the Notes to Financial Statements in the 2018 Form 10-K. In addition, see Part I, Item 1, Financial Statements, Notes D and E of Notes to Financial Statements above and Part II, Item 8, Financial Statements and Supplementary Data, Notes D and F of the Notes to Financial Statements in the 2018 Form 10-K regarding matters related to wholesale power sales contracts and transmission contracts subject to regulation and Palo Verde, including decommissioning, spent nuclear fuel and waste disposal, and liability and insurance matters.

Power Purchase and Sale Contracts

To supplement its own generation and operating reserve requirements and to meet its RPS requirements, the Company engages in power purchase arrangements that may vary in duration and amount based on an evaluation of the Company's resource needs, the economics of the transactions and specific RPS requirements. In the fourth quarter of 2019, the Company anticipates filing for regulatory approval with the NMPRC for two power purchase agreements relating to both solar and battery storage resources as a result of the Company's 2017 All Source Request for Proposal for Electric Power Supply and Load Management Resources. For a discussion of power purchase and sale contracts that the Company has entered into with various counterparties, see Part II, Item 8, Financial Statements and Supplementary Data, Note L of the Notes to Financial Statements in the 2018 Form 10-K.

Environmental Matters

The Company is subject to extensive laws, regulations and permit requirements with respect to air and greenhouse gas emissions, water discharges, soil and water quality, waste management and disposal, natural resources and other environmental matters by federal, state, regional, tribal and local authorities. Failure to comply with such laws, regulations and requirements can result in actions by authorities or other third parties that might seek to impose on the Company administrative, civil and/or criminal penalties or other sanctions. In addition, releases of pollutants or contaminants into the environment can result in costly cleanup liabilities. These laws, regulations and requirements are subject to change through modification or reinterpretation, or the introduction of new laws and regulations and, as a result, the Company may face additional capital and operating costs to comply.

Union Matters

The Company employs approximately 1,100 individuals, 37% of which are covered by a collective bargaining agreement. The International Brotherhood of Electrical Workers Local 960 ("Local 960") represents the Company’s employees working primarily in power generation, transmission and distribution, communications, material services, fleet services, facilities services, customer services and meter reading, and field services.

J. Litigation

The Company is involved in various legal, environmental, tax and regulatory proceedings before various courts, regulatory commissions and governmental agencies regarding matters arising in the ordinary course of business. In many of these matters, the Company has excess casualty liability insurance that covers the various claims, actions and complaints. The Company regularly analyzes current information and, as necessary, makes provisions in its financial statements for probable liabilities for the eventual disposition of these matters. While the outcome of these matters cannot be predicted with certainty, based upon a review of the matters and applicable insurance coverage, the Company believes that none of these matters will have a material adverse effect on the financial position, results of operations or cash flows of the Company. The Company expenses legal costs, including expenses related to loss contingencies, as they are incurred.

See Part I, Item 1, Financial Statements, Notes D and H of Notes to Financial Statements above and Part II, Item 8, Financial Statements and Supplementary Data, Notes D and L of the Notes to Financial Statements in the 2018 Form 10-K for discussion of the effects of government legislation and regulation on the Company.

Litigation Related to the Merger. As of November 7, 2019, three purported Company shareholders have filed lawsuits under the federal securities laws, two in the U.S. District Court for the Southern District of New York and one in the U.S. District Court for the District of Delaware, challenging the adequacy of the disclosures made in the Company’s preliminary proxy statement in connection with the Merger. These cases are captioned Stein v. El Paso Electric Company., et al., Case No. 1:19-cv-06703 (the “Stein Action”), Rosenblatt v. El Paso Electric Company., et al., Case No. 1:19-cv-01367-UNA (the “Rosenblatt Action”), and Gorski v. El Paso Electric Company., et. al., Case No. 1:19-cv-07211 (the “Gorski Action”), respectively. The Stein Action, filed on July 18, 2019, the Rosenblatt Action, filed on July 23, 2019, and the Gorski Action, filed on August 1, 2019, are asserted on behalf of putative classes of Company shareholders.

All three actions allege violations of Sections 14(a) and 20(a) of the Securities and Exchange Act of 1934, as amended (the "Exchange Act") and Rule 14a-9 promulgated thereunder based on various alleged omissions of material information from the preliminary proxy statement. The Stein Action names as defendants the Company and each of our directors, individually, and seeks to enjoin the Merger (or, in the alternative, rescission or an award of rescissory damages in the event the Merger is completed), damages, and an award of costs and attorneys’ and expert fees. The Rosenblatt Action names as defendants the Company and each of our directors, individually, and seeks to enjoin the Merger (or, in the alternative, rescission or an award of rescissory damages in the event the Merger is completed), to compel our directors to issue a revised proxy statement, a declaration that the defendants violated Sections 14(a) and 20(a) of the Exchange Act and Rule 14a-9 promulgated thereunder, and an award of costs and attorneys’ and expert fees. The Gorski Action also names as defendants the Company and each of our directors, individually, and seeks to enjoin the Merger (or, in the alternative, rescission or an award of rescissory damages in the event the Merger is completed), to compel our directors to issue a revised proxy statement, a declaration that the defendants violated Sections 14(a) and 20(a) of the Exchange Act and Rule 14a-9 promulgated thereunder, and an award of costs and attorneys’ and expert fees.

The Company believes that these complaints are without merit, and while the Company believes that the disclosures set forth in the proxy statement complied fully with applicable law, to moot plaintiffs’ disclosure claims, to avoid nuisance, potential expense and delay, and to provide additional information to the Company’s shareholders, the Company voluntarily supplemented the proxy statement with additional disclosure in a Current Report on Form 8-K filed by the Company with the SEC on September 9, 2019. While the outcome of these matters cannot be predicted with certainty, based upon a review of the matters and applicable insurance coverage, the Company believes that none of these matters will have a material adverse effect on the financial position, results of operations or cash flows of the Company. The Company expenses legal costs, including expenses related to loss contingencies, as they are incurred.

L. Financial Instruments and Investments

The FASB guidance requires the Company to disclose estimated fair values for its financial instruments. The Company has determined that cash and temporary investments, investment in debt securities, accounts receivable, decommissioning trust funds, long-term debt, short-term borrowings under the RCF, accounts payable and customer deposits meet the definition of financial instruments. The carrying amounts of cash and temporary investments, accounts receivable, accounts payable and customer deposits approximate fair value because of the short maturity of these items. Investments in debt securities and decommissioning trust funds are carried at estimated fair value.

Long-Term Debt and Short-Term Borrowings Under the RCF. The fair values of the Company's long-term debt and short-term borrowings under the RCF are based on estimated market prices for similar issues and are presented below (in thousands): 

	September 30, 2019				December 31, 2018
	Carrying Amount		Estimated Fair Value		Carrying Amount		Estimated Fair Value
Pollution Control Bonds (1)	$	157,947	$	167,977	$	157,769	$	161,917

_______________ 

(1) On February 1, 2019 and April 1, 2019, the Company purchased in lieu of redemption the 2009 Series A 7.25% PCBs with an aggregate principal amount of $63.5 million and the 2009 Series B 7.25% PCBs with an aggregate principal amount of $37.1 million, respectively, utilizing funds borrowed under the RCF. On May 22, 2019, the Company reoffered and sold $63.5 million aggregate principal amount of 2009 Series A 7.25% PCBs and $37.1 million aggregate principal amount of 2009 Series B 7.25% PCBs with a fixed interest rate of 3.60% per annum until the bonds mature on February 1, 2040 and April 1, 2040, respectively. See Part I, Item 1, Financial Statements, Note M of Notes to Financial Statements for further discussion.

(2) Nuclear fuel financing, as of September 30, 2019 and December 31, 2018, is funded through $110 million RGRT Senior Notes and $22.8 million and $26.2 million, respectively, under the RCF. As of September 30, 2019, $77.0 million was outstanding under the RCF for working capital and general corporate purposes. As of December 31, 2018, $23.0 million, was outstanding under the RCF for working capital or general corporate purposes. The interest rate on the Company's borrowings under the RCF is reset throughout the quarter reflecting current market rates. Consequently, the carrying value approximates fair value. See Part I, Item 1, Financial Statements, Note M of Notes to Financial Statements for further discussion.

Marketable Securities. The Company's marketable securities, included in decommissioning trust funds in the balance sheets, are reported at fair value which was $311.7 million and $276.9 million at September 30, 2019 and December 31, 2018, respectively. The investments in the Company's Palo Verde nuclear decommissioning trust funds ("NDT") are classified as equity securities and temporary cash and cash equivalents restricted solely for investment in the NDT. These investments are recorded at their estimated fair value in accordance with FASB guidance for certain investments in equity securities. On January 1, 2018, the Company adopted ASU 2016-01, Financial Instruments - Overall, which eliminates the requirements to classify investments in equity securities with readily determinable fair values as trading or available for sale and requires entities to recognize changes in fair value for these securities in net income as reported in the Statements of Operations. ASU 2016-01 requires a modified-retrospective approach and therefore, comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods.

During September 2019, the Company sold all of the fixed income securities classified as available for sale held in the NDT which approximated 450 individual securities. The proceeds were reinvested in three exchange traded funds that hold similar securities. The exchange traded funds meet the definition of equity securities with readily determinable fair values and therefore are not classified as available for sale as of September 30, 2019. Furthermore, changes in the fair value of these exchange traded funds will be recorded in net income as reported in the Statement of Operations, as required by ASU 2016-01.

(1) Includes 156 securities.

Prior to the sale of all the Company's fixed income securities classified as available for sale, the Company monitored the length of time such securities traded below their cost basis along with the amount and percentage of the unrealized loss in determining if a decline in fair value below recorded cost was considered to be other than temporary. In accordance with the FASB guidance, such impairment losses were recognized in net income, and a lower cost basis was established for these securities. For the three, nine and twelve months ended September 30, 2019 and 2018, the Company did not recognize any other than temporary impairment losses on its available for sale securities.

Investments categorized as available for sale securities also included gross unrealized gains which had not been recognized in the Company's net income prior to September 30, 2019.

Fair Value Measurements. The FASB guidance requires the Company to provide expanded quantitative disclosures for financial assets and liabilities recorded on the balance sheet at fair value. Financial assets carried at fair value include the Company's decommissioning trust investments and investments in debt securities which are included in deferred charges and other assets on the Balance Sheets. The Company has no liabilities that are measured at fair value on a recurring basis. The FASB guidance establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three levels as follows:

• Level 1 – Observable inputs that reflect quoted market prices for identical assets and liabilities in active markets. Financial assets utilizing Level 1 inputs include the NDT investments in active exchange-traded equity securities, mutual funds and U.S. Treasury securities that are in a highly liquid and active market. The Institutional Funds - International Equity investments are valued using the Net Asset Value ("NAV") provided by the administrator of the fund. The NAV price is quoted on a restrictive market although the underlying investments are traded on active markets. The NAV used for determining the fair value of the Institutional Funds-International Equity investments have readily determinable fair values. Accordingly, such fund values are categorized as Level 1.

• Level 2 – Inputs other than quoted market prices included in Level 1 that are observable for the asset or liability either directly or indirectly. Financial assets utilizing Level 2 inputs included the NDT investments in fixed income securities that were sold by the Company on September 30, 2019, and reinvested in similar fixed income securities held in three exchange traded funds. The fair value of these financial instruments is based on evaluated prices that reflect observable market information, such as actual trade information of similar securities, adjusted for observable differences.

• Level 3 – Unobservable inputs using data that is not corroborated by market data and primarily based on internal Company analysis using models and various other analysis. Financial assets utilizing Level 3 inputs are the Company's investment in debt securities.

The securities in the NDT are valued using prices and other relevant information generated by market transactions involving identical or comparable securities. The FASB guidance identifies this valuation technique as the "market approach" with observable

inputs. Prior to the sale of all the Company's fixed income securities classified as available for sale in September 2019, the Company analyzed available for sale securities to determine if losses were other than temporary.

The fair value of the NDT and investments in debt securities at September 30, 2019 and December 31, 2018, and the level within the three levels of the fair value hierarchy defined by the FASB guidance are presented in the table below (in thousands):

M. Long-Term Debt and Financing Obligations

Pollution Control Bonds. The Company had three series of tax-exempt unsecured PCBs in aggregate principal amount of $159.8 million as of December 31, 2018. The 2009 Series A 7.25% PCBs and the 2009 Series B 7.25% PCBs with an aggregate principal amount, together, of $100.6 million had optional redemptions beginning in February 2019 and April 2019, respectively.

The Company purchased in lieu of redemption all of the 2009 Series A 7.25% PCBs with an aggregate principal amount of $63.5 million, and all of the 2009 Series B 7.25% PCBs with an aggregate principal amount of $37.1 million, on February 1, 2019 and April 1, 2019, respectively, utilizing funds borrowed under the RCF.

On May 22, 2019, the Company reoffered and sold $63.5 million aggregate principal amount of 2009 Series A 7.25% PCBs and $37.1 million aggregate principal amount of 2009 Series B 7.25% PCBs with a fixed interest rate of 3.60% per annum until the bonds mature on February 1, 2040 and April 1, 2040, respectively. The bonds are subject to optional redemption at a redemption price of par on or after June 1, 2029. Proceeds from the remarketing were primarily used to repay outstanding short-term borrowings under the RCF.

Revolving Credit Facility. The Company has a $350 million RCF for working capital and general corporate purposes and financing nuclear fuel through the RGRT with a term ending on September 13, 2023. The Merger would constitute a "Change in Control" under the RCF and the consummation of the Merger would result in an event of default under the RCF. On and subject to the terms and conditions of the Merger Agreement, the Company requested that the lenders under the RCF consent to the Merger and waive any default or event of default that would occur as a result of the Merger. On August 9, 2019, the lenders agreed to such consent and waiver.

Under the Merger Agreement, subject to certain exceptions, the Company cannot incur additional indebtedness over $200 million (excluding borrowings up to the existing borrowing capacity of the RCF), without the prior written consent of Parent.    

N. Agreement and Plan of Merger

On June 1, 2019, the Company entered into the Merger Agreement, by and among the Company, Parent, and Merger Sub. Pursuant to the Merger Agreement, on and subject to the terms and conditions set forth therein, Merger Sub will merge with and into the Company, with the Company continuing as the surviving corporation in the Merger and becoming a wholly owned subsidiary of Parent. Parent and Merger Sub are affiliates of IIF.

On and subject to the terms and conditions set forth in the Merger Agreement, upon the closing of the Merger, each share of common stock of the Company shall be cancelled and converted into the right to receive $68.25 in cash, without interest (the "Merger Consideration").

The Company, Parent and Merger Sub each have made various representations, warranties and covenants in the Merger Agreement. Among other things, the Company has agreed, subject to certain exceptions, to conduct its business in the ordinary course, consistent with past practice, from the date of the Merger Agreement until the closing of the Merger, and not to take certain actions prior to the closing of the Merger without the prior written consent of Parent (which consent shall not be unreasonably withheld, conditioned or delayed). The Company has made certain additional customary covenants, including, subject to certain exceptions: (1) to cause a meeting of the Company’s shareholders to be held to consider approval of the Merger Agreement, (2) not to solicit proposals relating to alternative business combination transactions and not to participate in discussions concerning, or furnish information in connection with, alternative business combination transactions and (3) not to withdraw its recommendation to the Company’s shareholders regarding the Merger. In addition, subject to the terms of the Merger Agreement, the Company, Parent and Merger Sub are required to use reasonable best efforts to obtain all required regulatory approvals, which will include clearance under federal antitrust laws and certain approvals by federal and state regulatory bodies, subject to certain exceptions, including that such efforts not result in a Burdensome Condition (as defined in the Merger Agreement). Parent has obtained equity and debt financing commitments for the transactions contemplated by the Merger Agreement, the aggregate proceeds of which will be sufficient to consummate the Merger and the other transactions contemplated by the Merger Agreement, including payment of the aggregate Merger Consideration.

Consummation of the Merger is subject to various conditions, including: (1) approval of the shareholders of the Company, (2) expiration or termination of the applicable HSR Act waiting period, (3) receipt of all required regulatory and statutory approvals without the imposition of a Burdensome Condition, (4) absence of any law or order prohibiting the consummation of the Merger and (5) other customary closing conditions, including (a) subject to materiality qualifiers, the accuracy of each party's representations

36

EL PASO ELECTRIC COMPANY

NOTES TO FINANCIAL STATEMENTS

(Unaudited)

and warranties, (b) each party's compliance in all material respects with its obligations and covenants under the Merger Agreement and (c) the absence of a material adverse effect with respect to the Company.

The Merger Agreement contains certain termination rights for both the Company and Parent, including if the Merger is not consummated by June 1, 2020 (subject to extension for an additional three months if all of the conditions to closing, other than the conditions related to obtaining regulatory approvals, have been satisfied). The Merger Agreement also provides for certain termination rights for each of the Company and Parent, and provides that, upon termination of the Merger Agreement under certain specified circumstances, Parent would be required to pay a termination fee of $170 million to the Company, and under other specified circumstances, the Company would be required to pay Parent a termination fee of $85 million.

On August 2, 2019, the Company filed a definitive proxy statement with the SEC in connection with the Merger. As of November 7, 2019, three purported Company shareholders have filed lawsuits alleging violations under the federal securities laws, two in the U.S. District Court for the Southern District of New York and one in the U.S. District Court for the District of Delaware, challenging the adequacy of the disclosures made in the Company's proxy statement in connection with the Merger as discussed in Part I, Item 1, Financial Statements, Note J of Notes to Financial Statements.

On August 13, 2019, the Company, Parent and IIF US Holdings 2 LP, an affiliate of IIF, as applicable, filed (1) the joint report and application for regulatory approvals with the PUCT requesting approval of the Merger pursuant to the PURA, (2) the joint application for regulatory approvals with the NMPRC requesting approval of the Merger pursuant to the NMPUA and NMPRC Rule 450, (3) the joint application requesting approval of the Merger with the FERC under Section 203 of the Federal Power Act and (4) the joint application for regulatory approval for the indirect transfer of the Company’s NRC licenses to Parent from the NRC under the Atomic Energy Act of 1954. In addition, on August 13, 2019, the Company and Parent sought the authorization of the FCC to assign or transfer control of the Company’s FCC licenses.

On August 16, 2019, the Company and Parent filed the notification and report form with the Antitrust Division of the Department of Justice and the FTC under the HSR Act. On September 3, 2019, the Company and Parent received notice from the FTC granting early termination of the waiting period under the HSR Act. 

Under the Merger Agreement, the consent to the Merger by the City of El Paso under its franchise agreement with the Company is a condition to the closing of the Merger. Under the franchise agreement, if the City of El Paso does not grant its consent to the Merger, the franchise agreement would terminate upon the closing of the Merger. On September 20, 2019, the Company submitted the franchise agreement assignment application to the City of El Paso.

At a special meeting of the Company's shareholders held on September 19, 2019, the Company’s shareholders approved the Merger Agreement and the transactions contemplated thereby, including the Merger, and the compensation that will or may become payable by the Company to its named executive officers in connection with the Merger.

Subject to receipt of remaining approvals and satisfaction of the other closing conditions, the Company anticipates that the closing of the Merger will occur in the first half of 2020.

For more information regarding the terms of the Merger, including a copy of the Merger Agreement, see the Company's Current Report on Form 8-K filed with the SEC on June 3, 2019, and its definitive proxy statement relating to the special meeting of shareholders filed with the SEC on August 2, 2019.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors

El Paso Electric Company:

Results of Review of Interim Financial Information

We have reviewed the balance sheet of El Paso Electric Company (the "Company") as of September 30, 2019, the related statements of operations and comprehensive operations for the three-month, nine-month and twelve-month periods ended September 30, 2019 and 2018, the related statements of changes in common stock equity for the three-month and nine-month periods ended September 30, 2019 and 2018, the related statements of cash flows for the nine-month periods ended September 30, 2019 and 2018, and the related condensed notes (collectively, the interim financial information). Based on our reviews, we are not aware of any material modifications that should be made to the interim financial information for it to be in conformity with U.S. generally accepted accounting principles.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the balance sheet of the Company as of December 31, 2018, and the related statements of operations and comprehensive operations, changes in common stock equity, and cash flows for the year then ended (not presented herein); and in our report dated February 28, 2019, we expressed an unqualified opinion on those financial statements. In our opinion, the information set forth in the accompanying balance sheet as of December 31, 2018, is fairly stated, in all material respects, in relation to the balance sheet from which it has been derived.

Basis for Review Results

This interim financial information is the responsibility of the Company’s management. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our reviews in accordance with the standards of the PCAOB. A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the PCAOB, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

FORWARD-LOOKING STATEMENTS

Certain matters discussed in this Quarterly Report on Form 10-Q, other than statements of historical fact, are “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Exchange Act. Forward-looking statements often include words like "believe", "anticipate", "target", "project", "expect", "predict", "pro forma", "estimate", "intend", "will", "is designed to", "plan", and words of similar meaning, or are indicated by the Company's discussion of strategies or trends. Forward-looking statements describe the Company's future plans, objectives, expectations or goals. Although the Company believes that the expectations reflected in such forward-looking statements are reasonable, no assurances can be given that these expectations will prove to be correct. Such statements address future events and conditions and include, but are not limited to:

• capital expenditures,

• earnings,

• liquidity and capital resources,

• ratemaking/regulatory matters/compliance matters,

• litigation,

• nuclear operations,

• operation of the Company's generating units and its transmission and distribution systems,

• the availability and costs of new and/or emerging technologies, and

• the overall economy of the Company's service area.

These forward-looking statements are based on assumptions and analyses in light of the Company's experience and perception of historical trends, current conditions, expected future developments, and other factors the Company believes were appropriate in the circumstances when the statements were made. Forward-looking statements by their nature involve substantial risks and uncertainties that could significantly impact expected results, and actual future results could differ materially from those described in such statements. While it is not possible to identify all factors, the Company continues to face many risks and uncertainties. Factors that would cause or contribute to such differences include, but are not limited to:

• decisions and actions of the Company's regulators and the resulting impact on the Company's operations, cost of capital, sales, and profitability,

• the Company's ability to fully and timely recover its costs and earn a reasonable rate of return on its invested capital through the rates that it is permitted to charge,

• rates, cost recovery mechanisms and other regulatory matters including the ability to recover fuel costs on a timely basis,

• the ability of the Company's operating partners to maintain plant operations and manage operations and maintenance ("O&M") costs at Palo Verde and its related transmission, including costs to comply with any new or expanded regulatory or environmental requirements,

• reductions in output at generation plants operated by the Company,

• the size of the Company's construction program and its ability to complete construction on budget and on time,

39

• the receipt of required approvals by regulators and other permits related to the Company’s construction programs,

• the Company's reliance on significant customers,

• the credit worthiness of the Company's customers,

• unscheduled outages of generating units including outages at Palo Verde,

• changes in customers' demand for electricity as a result of energy efficiency initiatives and emerging competing services and technologies, including distributed generation and battery storage,

• individual customer groups, including distributed generation customers, may not pay their full cost of service, and other customers may or may not be required to pay the difference,

• changes in, and the assumptions used for, pension and other post-retirement and post-employment benefit liability calculations, as well as actual and assumed investment returns on pension plan and other post-retirement plan assets,

• the impact of changing cost escalation and other assumptions on the Company's nuclear decommissioning liability for Palo Verde, as well as actual and assumed investment returns on assets in the NDT,

• disruptions in the Company's transmission and distribution systems, and in particular the lines that deliver power from its remote generating facilities,

• the sufficiency of the Company's insurance coverage, including availability, cost, coverage and terms,

• electric utility deregulation or re-regulation,

Summary of Critical Accounting Policies and Estimates

The preparation of our financial statements requires management to make estimates and assumptions that affect the amounts reported in the financial statements and related notes for the periods presented and actual results could differ in future periods from those estimates. Critical accounting policies and estimates are both important to the portrayal of our financial condition and results of operations and require complex, subjective judgments and are more fully described in the "Management's Discussion and Analysis of Financial Condition and Results of Operations" in the 2018 Form 10-K.

Significant Events

Merger with Sun Jupiter Holdings LLC

On June 1, 2019, the Company entered into the Merger Agreement, by and among the Company, Parent, and Merger Sub. Pursuant to the Merger Agreement, on and subject to the terms and conditions set forth therein, Merger Sub will merge with and into the Company, with the Company continuing as the surviving corporation in the Merger and becoming a wholly owned subsidiary of Parent. Parent and Merger Sub are affiliates of IIF.

On and subject to the terms and conditions set forth in the Merger Agreement, upon the closing of the Merger, each share of common stock of the Company shall be cancelled and converted into the right to receive $68.25 in cash, without interest.

The Company, Parent and Merger Sub each have made various representations, warranties and covenants in the Merger Agreement. Among other things, the Company has agreed, subject to certain exceptions, to conduct its business in the ordinary course, consistent with past practice, from the date of the Merger Agreement until the closing of the Merger, and not to take certain actions prior to the closing of the Merger without the prior written consent of Parent (which consent shall not be unreasonably withheld, conditioned or delayed). The Company has made certain additional customary covenants, including, subject to certain exceptions: (1) to cause a meeting of the Company’s shareholders to be held to consider approval of the Merger Agreement, (2) not to solicit proposals relating to alternative business combination transactions and not to participate in discussions concerning, or furnish information in connection with, alternative business combination transactions and (3) not to withdraw its recommendation to the Company’s shareholders regarding the Merger. In addition, subject to the terms of the Merger Agreement, the Company, Parent and Merger Sub are required to use reasonable best efforts to obtain all required regulatory approvals, which will include clearance under federal antitrust laws and certain approvals by federal and state regulatory bodies, subject to certain exceptions, including that such efforts not result in a Burdensome Condition (as defined in the Merger Agreement). Parent has obtained equity and debt financing commitments for the transactions contemplated by the Merger Agreement, the aggregate proceeds of which will be sufficient to consummate the Merger and the other transactions contemplated by the Merger Agreement, including payment of the aggregate Merger Consideration.

Consummation of the Merger is subject to various conditions, including: (1) approval of the shareholders of the Company, (2) expiration or termination of the applicable HSR Act waiting period, (3) receipt of all required regulatory and statutory approvals without the imposition of a Burdensome Condition, (4) absence of any law or order prohibiting the consummation of the Merger and (5) other customary closing conditions, including (a) subject to materiality qualifiers, the accuracy of each party's representations and warranties, (b) each party's compliance in all material respects with its obligations and covenants under the Merger Agreement and (c) the absence of a material adverse effect with respect to the Company.

The Merger Agreement contains certain termination rights for both the Company and Parent, including if the Merger is not consummated by June 1, 2020 (subject to extension for an additional three months if all of the conditions to closing, other than the conditions related to obtaining regulatory approvals, have been satisfied). The Merger Agreement also provides for certain termination rights for each of the Company and Parent, and provides that, upon termination of the Merger Agreement under certain specified circumstances, Parent would be required to pay a termination fee of $170 million to the Company, and under other specified circumstances, the Company would be required to pay Parent a termination fee of $85 million.

On August 2, 2019, the Company filed a definitive proxy statement with the SEC in connection with the Merger. As of November 7, 2019, three purported Company shareholders have filed lawsuits alleging violations under the federal securities laws, two in the U.S. District Court for the Southern District of New York and one in the U.S. District Court for the District of Delaware, challenging the adequacy of the disclosures made in the Company's proxy statement in connection with the Merger as discussed in Part I, Item 1, Financial Statements, Note J of Notes to Financial Statements.

On August 13, 2019, the Company, Parent and IIF US Holdings 2 LP, an affiliate of IIF, as applicable, filed (1) the joint report and application for regulatory approvals with the PUCT requesting approval of the Merger pursuant to the PURA, (2) the joint application for regulatory approvals with the NMPRC requesting approval of the Merger pursuant to the NMPUA and NMPRC Rule 450, (3) the joint application requesting approval of the Merger with the FERC under Section 203 of the Federal Power Act and (4) the joint application for regulatory approval for the indirect transfer of the Company’s NRC licenses to Parent from the NRC under the Atomic Energy Act of 1954. In addition, on August 13, 2019, the Company and Parent sought the authorization of the FCC to assign or transfer control of the Company’s FCC licenses.

On August 16, 2019, the Company and Parent filed the notification and report form with the Antitrust Division of the Department of Justice and the FTC under the HSR Act. On September 3, 2019, the Company and Parent received notice from the FTC granting early termination of the waiting period under the HSR Act.

Under the Merger Agreement, the consent to the Merger by the City of El Paso under its franchise agreement with the Company is a condition to the closing of the Merger. Under the franchise agreement, if the City of El Paso does not grant its consent to the Merger, the franchise agreement would terminate upon the closing of the Merger. On September 20, 2019, the Company submitted the franchise agreement assignment application to the City of El Paso.

At a special meeting of the Company's shareholders held on September 19, 2019, the Company’s shareholders approved the Merger Agreement and the transactions contemplated thereby, including the Merger, and the compensation that will or may become payable by the Company to its named executive officers in connection with the Merger.

Subject to receipt of remaining approvals and satisfaction of the other closing conditions, the Company anticipates that the closing of the Merger will occur in the first half of 2020.

In connection with the proposed Merger, the Company recorded merger-related expenses of $9.5 million, principally related to advisory fees, legal, and other consulting costs, in the nine months ending September 30, 2019, which are reflected in Other income (deductions) - Strategic transaction costs in the Statements of Operations. Upon completion of the Merger, the Company will evaluate the tax deductibility of these costs and will reflect any non-deductible amounts in the effective tax rate at the Merger closing date.

______________

All information presented below is expressed in pre-tax amounts except when stated otherwise.

43

(a) Retail non-fuel base revenues increased for the three months ended September 30, 2019, compared to the three months ended September 30, 2018, primarily due to increased revenues from (i) residential customers of $11.3 million caused by increased kWh sales, (ii) small commercial and industrial customers of $1.5 million caused by increased kWh sales, and (iii) sales to public authorities of $1.3 million caused by increased kWh sales. These increases in kWh sales primarily resulted from favorable weather and overall customer growth of 1.6% when compared to the three months ended September 30, 2018. Retail kWh sales in the three months ended September 30, 2019 grew 5.0% when compared to the three months ended September 30, 2018, which set a record for kWh consumption during any calendar quarter.

Retail non-fuel base revenues increased for the nine months ended September 30, 2019, compared to the nine months ended September 30, 2018, primarily due to a $3.8 million increase related to the 1% increase in the City of El Paso franchise fee on gross revenues for services within the City of El Paso applicable to customer billings issued on or after October 1, 2018. Overall, kWh sales for the nine months ended September 30, 2019 declined primarily due to milder weather in the three months ended June 30, 2019, which was substantially offset by record sales in the three months ended September 30, 2019, due to favorable weather and overall customer growth of 1.6% when compared to the three months ended September 30, 2018.

Retail non-fuel base revenues decreased for the twelve months ended September 30, 2019, compared to the twelve months ended September 30, 2018, primarily due to refunds of approximately $28.4 million during the twelve months ended September 30, 2019, for the reduction in the federal corporate income tax rate due to the TCJA, offset by (i) refunds of approximately $22.6 million during the twelve months ended September 30, 2018, and (ii) an increase of $4.9 million due to the 1% increase in the City of El Paso franchise fee on gross revenues for services within the City of El Paso applicable to customer billings issued on or after October 1, 2018. For the twelve months ended September 30, 2018, rate changes included additional revenues of approximately $4.8 million related to the period from July 18, 2017 through September 30, 2017. These relate back revenues were recognized when the 2017 PUCT Final Order was approved in December 2017.

(b) O&M expenses at our fossil-fuel generating plants decreased for the three months ended September 30, 2019, compared to the three months ended September 30, 2018, primarily due to decreased outage costs at Newman Unit 2 and decreased maintenance costs at Newman.

O&M expenses at our fossil-fuel generating plants decreased for the nine and twelve months ended September 30, 2019, compared to the nine and twelve months ended September 30, 2018, primarily due to decreased outage costs at Newman Units 1 & 2 and Rio Grande Power Station ("Rio Grande") Unit 8, and decreased maintenance costs at Newman. These decreases were partially offset by increased outage costs at Newman Unit 4 and increased maintenance costs at MPS.

(c) Wheeling revenues increased for the three, nine and twelve months ended September 30, 2019, compared to the three, nine and twelve months ended September 30, 2018, primarily due to an increase in short-term transmission sales due to favorable market conditions.

(d) Investment and interest income, NDT decreased for the three and twelve months ended September 30, 2019, compared to the three and twelve months ended September 30, 2018, primarily due to lower net realized and unrealized gains on securities held in the NDT associated primarily with the relative performance of the equity markets.

Investment and interest income, NDT increased for the nine months ended September 30, 2019, compared to the nine months ended September 30, 2018, primarily due to higher net realized and unrealized gains on securities held in the NDT associated primarily with the relative performance of the equity markets.

Refer to "Use of Non-GAAP Financial Measures" below for further details.

(e) Strategic transaction costs increased for the three, nine and twelve months ended September 30, 2019, compared to the three, nine and twelve months ended September 30, 2018, due to costs incurred in connection with the Merger.

(f) Depreciation and amortization increased for the three, nine and twelve months ended September 30, 2019, compared to the three, nine and twelve months ended September 30, 2018, primarily due to increased plant balances.

(g) Administrative and general ("A&G") expenses decreased for the nine months ended September 30, 2019, compared to the nine months ended September 30, 2018, primarily due to decreased long-term stock incentive plan costs and changes in actuarial assumptions used to calculate expenses for retirement benefit plans, including an increase in the discount rate. These decreases were partially offset by a higher amount of accrued employee incentive compensation.

44

A&G expenses decreased for the twelve months ended September 30, 2019, compared to the twelve months ended September 30, 2018, primarily due to decreased long-term stock incentive plan costs and changes in actuarial assumptions used to calculate expenses for retirement benefit plans, including an increase in the discount rate.

Use of Non-GAAP Financial Measures

As required by ASU 2016-01, Financial Instruments - Recognition and Measurement of Financial Assets and Financial Liabilities, changes in the fair value of equity securities are recognized in the Company's Statements of Operations. This standard added the potential for significant volatility to the Company's reported results of operations as changes in the fair value of equity securities may occur. Furthermore, the equity investments included in the NDT are significant and are expected to increase significantly during the remaining life (estimated to be 26 to 29 years) of Palo Verde. Accordingly, the Company has provided the following non-GAAP financial measures to exclude the impact of changes in fair value of equity securities and realized gains (losses) from the sale of both equity and fixed income securities. Reconciliations of both non-GAAP financial measures to the most directly comparable financial information presented in accordance with GAAP are presented in the tables below. Non-GAAP adjusted net income is reconciled to GAAP net income, and non-GAAP adjusted basic earnings per share is reconciled to GAAP basic earnings per share.

(1) Net income (GAAP) and Adjusted net income (non-GAAP) include a pre-tax charge of $9.5 million, or $0.19 per share, after-tax, of strategic transaction costs.

Adjusted net income and adjusted basic earnings per share are not measures of financial performance under GAAP and should not be considered as an alternative to net income and basic earnings per share, respectively. Furthermore, the Company's presentation of any non-GAAP financial measure may not be comparable to similarly titled measures used by other companies. The Company believes adjusted net income and adjusted basic earnings per share are useful financial measures for investors and analysts in understanding the Company's core operating performance because each measure removes the effects of variances reported in the Company's results of operations that are not indicative of fundamental changes in the earnings capacity of the Company. Non-GAAP financial information should be read together with, and is not an alternative or substitute for, the Company's financial results reported in accordance with GAAP.

Historical Results of Operations

The following discussion includes detailed descriptions of factors affecting individual line items in the results of operations. The amounts presented below are presented on a pre-tax basis.

Operating revenues

We realize revenue from the sale of electricity to retail customers at regulated rates and the sale of energy in the wholesale power market generally at market-based prices. Sales for resale to our sole full requirement customer (which are FERC-regulated cost-based wholesale sales within our service territory) accounted for less than 1% of revenues.

Revenues from the sale of electricity include fuel costs that are recovered from our customers through fuel adjustment mechanisms. We record deferred fuel revenues for the difference between actual fuel costs and recoverable fuel revenues until such amounts are collected from or refunded to customers. "Non-fuel base revenues" refers to our revenues from the sale of electricity excluding such fuel costs.    

No retail customer accounted for more than 3% of our non-fuel base revenues for the three, nine and twelve months ended September 30, 2019. Residential and small commercial customers represent approximately 79% of our non-fuel base revenues. While this customer base is more stable, it is also more sensitive to changes in weather conditions. The current rate structures in Texas and New Mexico reflect higher base rates during the peak summer season of May through October and lower base rates during November through April for our residential and small commercial and industrial customers. As a result, our business is seasonal, with higher kWh sales and revenues during the summer cooling season.

Weather significantly impacts our residential, small commercial and industrial customers, and to a lesser extent, our sales to public authorities. Heating and cooling degree days can be used to evaluate the effect of weather on energy use. For each degree the average outdoor temperature varies from a standard of 65 degrees Fahrenheit, a degree day is recorded. For the three months ended September 30, 2019, retail non-fuel base revenues were positively impacted by favorable weather when compared to the three months ended September 30, 2018. Cooling degree days for the three months ended September 30, 2019 increased 10.5% when compared to the three months ended September 30, 2018, and were 16.1% above the 10-year average. For the nine and twelve months ended September 30, 2019, retail non-fuel base revenues were negatively impacted by overall milder weather when compared to the nine and twelve months ended September 30, 2018. Cooling degree days for the nine and twelve months ended September 30, 2019 decreased 6.0% and 8.4% when compared to the nine and twelve months ended September 30, 2018, respectively, but were 4.9% and 4.4% above the 10-year average, respectively. The table below shows heating and cooling degree days compared to a 10-year average for the periods in 2019 and 2018.

	Three Months Ended			Nine Months Ended			Twelve Months Ended
	September 30,			September 30,			September 30,

* Calendar year basis.

Customer growth is a key driver of the growth of retail sales. The average number of retail customers grew 1.6% for the three, nine and twelve months ended September 30, 2019, when compared to the three, nine and twelve months ended September 30, 2018. See the tables presented on pages 49, 50 and 51, which provide detail on the average number of retail customers and the related revenues and kWh sales.

Retail non-fuel base revenues. Retail non-fuel base revenues for the three months ended September 30, 2019, increased $13.8 million, or 6.4%, compared to the three months ended September 30, 2018. Retail non-fuel base revenues increased primarily due to increased revenues from (i) residential customers of $11.3 million caused by a 10.1% increase in kWh sales, (ii) small commercial and industrial customers of $1.5 million caused by a 1.9% increase in kWh sales, and (iii) sales to public authorities of $1.3 million caused by a 3.5% increase in kWh sales compared to the three months ended September 30, 2018. The increases in kWh sales resulted primarily from favorable weather and overall customer growth of 1.6% in the three months ended September 30, 2019, when compared to the three months ended September 30, 2018. Retail kWh sales grew 5.0% over the three months ended September 30, 2018, which set a record for kWh consumption during any calendar quarter. During the three months ended September 30, 2019, the Company also set a peak demand record. On August 7, 2019, the Company recorded a peak demand of 1,952 MW. Subsequently, on August 26, 2019, the Company recorded a peak demand of 1,985 MW, which exceeds the previous record established prior to August 2019 by 50 MW, or 2.6%, set on June 22, 2017.

47

Retail non-fuel base revenues for the nine months ended September 30, 2019, increased $2.6 million, or 0.5%, compared to the nine months ended September 30, 2018. Retail non-fuel base revenues increased primarily due to a $3.8 million increase related to the 1% increase in the City of El Paso franchise fee on gross revenues for services within the City of El Paso applicable to customer billings issued on or after October 1, 2018. Overall, kWh sales for the nine months ended September 30, 2019 declined 0.7%, primarily due to milder weather in the second quarter of 2019, which was substantially offset by record sales in the third quarter of 2019 due to favorable weather and overall customer growth of 1.6%.

Retail non-fuel base revenues for the twelve months ended September 30, 2019, decreased $6.4 million, or 1.0%, compared to the twelve months ended September 30, 2018. For the twelve months ended September 30, 2019, rate changes included the refunds to customers for the reduction in the federal corporate income tax rate due to the TCJA of approximately $28.4 million, compared to $22.6 million for the twelve months ended September 30, 2018. The reduction in rates due to the TCJA was offset by an increase of $4.9 million for the twelve months ended September 30, 2019, related to the 1% increase in the City of El Paso franchise fee on gross revenues for services within the City of El Paso applicable to customer billings issued on or after October 1, 2018. For the twelve months ended September 30, 2018, rate changes included additional revenues of approximately $4.8 million related to the period from July 18, 2017 through September 30, 2017. These relate back revenues were recognized when the 2017 PUCT Final Order was approved in December 2017.

Fuel revenues. Fuel revenues consist of revenues collected from customers under fuel recovery mechanisms approved by the state commissions and the FERC, and deferred fuel revenues, which are comprised of the difference between fuel costs and fuel revenues collected from customers. In New Mexico, fuel and purchased power costs, net of the cost of off-system sales and related shared margins, are reconciled to actual costs on a monthly basis and recovered or refunded to customers the second succeeding month. Additionally, the RPS costs for New Mexico are recovered through a separate RPS Cost Rider, which is updated annually. In Texas, fuel and purchased power costs, net of shared margins on off-system sales, are recovered through a fixed fuel factor. We can seek to revise our fixed fuel factor based upon an approved formula at least four months after our last revision, except in the month of December. In addition, if we materially over-recover fuel costs, we must seek to refund the over-recovery, and if we materially under-recover fuel costs, we may seek a surcharge to recover those costs. Fuel over- and under-recoveries are defined as material when they exceed 4% of the previous twelve months' fuel costs.

In the three, nine and twelve months ended September 30, 2019, we over-recovered fuel costs by $5.2 million, $23.2 million and $24.3 million, respectively. In June 2019 and March 2018, $1.0 million and $1.1 million, respectively, were credited to customers through the applicable fuel adjustment clauses as the result of a reimbursement from the DOE related to spent nuclear fuel storage. At September 30, 2019, we had a net fuel over-recovery balance of $14.4 million, including over-recoveries of $14.1 million in our Texas, $0.2 million in our New Mexico and $0.1 million in our FERC jurisdictions. On October 15, 2018, we filed a request with the PUCT to decrease our Texas fixed fuel factor by approximately 6.99% to reflect decreased fuel expenses primarily related to a decrease in the price of natural gas used to generate power. On October 25, 2018, our fixed fuel factor was approved on an interim basis effective for the first billing cycle of the November 2018 billing month. The revised factor was approved by the PUCT and the docket closed on November 19, 2018. On September 13, 2019, we filed a request with the PUCT to decrease our Texas fixed fuel factor by approximately 12.2% to reflect decreased fuel expenses primarily related to a decrease in the price of natural gas used to generate power. On September 25, 2019, our fixed fuel factor was approved on an interim basis effective for the first billing cycle of the October 2019 billing month. The Texas fixed fuel factor was determined to be final on October 15, 2019, and will continue until changed by the PUCT.

On April 29, 2019, we filed a petition with the PUCT requesting authority to implement, beginning on June 1, 2019, a four-month, interim fuel refund of $19.4 million in fuel cost over-recoveries, including interest, for the period from April 2016 through March 2019. On May 30, 2019, the fuel refund credit was approved on an interim basis. We implemented the fuel refund in customer bills on June 1, 2019. On September 27, 2019, the PUCT issued a final order approving the fuel refund credits. The fuel refund was completed on September 30, 2019, with a total fuel refund of $20.1 million, including interest, returned to Texas customers.

Off-system sales. Off-system sales are sales into wholesale markets outside our service territory. Off-system sales are primarily made in off-peak periods when we have competitive generation capacity available after meeting our regulated service obligations. We have shared 100% of margins on non-arbitrage sales (as defined by the settlement in PUCT Docket No. 41852) and 50% of margins on arbitrage sales with our Texas customers since April 1, 2014. We are currently sharing 90% of off-system sales margins with our New Mexico customers (as reaffirmed in NMPRC Case No. 09-00171-UT), and 25% of our off-system sales margins with our sales for resale - full requirement customer under the terms of its contract. Palo Verde's availability is an important factor in realizing these off-system sales margins.

Off-system sales revenue decreased $9.4 million, or 34.8%, for the three months ended September 30, 2019, compared to the three months ended September 30, 2018, as a result of a 1.6% decrease in kWh sales due to a decrease in available power and lower average market prices for power. Off-system sales revenue increased $5.2 million, or 8.8%, for the nine months ended September 30, 2019, compared to the nine months ended September 30, 2018, as a result of a 13.8% increase in kWh sales due to favorable market conditions, offset by lower average market prices for power. Off-system sales revenue increased $16.4 million,

48

or 21.8%, for the twelve months ended September 30, 2019, compared to the twelve months ended September 30, 2018, as a result of a 18.9% increase in kWh sales due to favorable market conditions.

Fuel and purchased power expense

Our sources of energy include electricity generated from our nuclear and natural gas generating plants and purchased power. Palo Verde represents approximately 30% of our net dependable generating capacity and approximately 44%, 50% and 49% of our Company-generated energy for the three, nine and twelve months ended September 30, 2019, respectively. Fluctuations in the price of natural gas, which also is the primary factor influencing the price of purchased power, have had a significant impact on our cost of energy.

Fuel and purchased power expense decreased $20.5 million, or 28.8%, for the three months ended September 30, 2019 compared to the three months ended September 30, 2018, primarily due to (i) decreased natural gas costs of $17.7 million primarily due to a 47.9% decrease in the average cost of Megawatt-hours ("MWhs") generated, partially offset by a 7.2% increase in MWhs generated with natural gas, and (ii) decreased total purchased power costs of $3.3 million primarily due to a 19.4% decrease in the average cost of MWhs purchased.

Operations and maintenance expense decreased $1.2 million, or 1.4%, for the three months ended September 30, 2019, compared to the three months ended September 30, 2018, primarily due to decreases of (i) $1.5 million in outage costs at Newman Unit 2, and (ii) $0.8 million in maintenance costs at Newman. These decreases were partially offset by increases of (i) $0.4 million in O&M expenses at Palo Verde, and (ii) $0.4 million in A&G expense primarily due to a higher amount of accrued employee incentive compensation.

Operations and maintenance expense decreased $8.5 million, or 3.4%, for the nine months ended September 30, 2019, compared to the nine months ended September 30, 2018, primarily due to decreases of (i) $4.8 million in outage costs at Newman Units 1 and 2, (ii) $3.2 million in outage costs at Rio Grande Unit 8, (iii) $2.3 million in A&G expense primarily due to decreased long-term stock incentive plan costs and changes in actuarial assumptions used to calculate expenses for retirement benefit plans, including an increase in the discount rate, partially offset by a higher amount of accrued employee incentive compensation, (iv) $1.4 million in maintenance costs at Newman, and (v) $1.1 million in O&M expenses at Palo Verde. These decreases were partially offset by increases of (i) $2.8 million in outage costs at Newman Unit 4, and (ii) $0.9 million in maintenance costs at MPS.

Operations and maintenance expense decreased $10.1 million, or 3.0%, for the twelve months ended September 30, 2019, compared to the twelve months ended September 30, 2018, primarily due to decreases of (i) $3.6 million in outage costs at Newman Units 1 and 2, (ii) $3.5 million in O&M expenses at Palo Verde, (iii) $3.2 million in outage costs at Rio Grande Unit 8, (iv) $2.9 million in A&G expense primarily due to decreased long-term stock incentive plan costs and changes in actuarial assumptions used to calculate expenses for retirement benefit plans, including an increase in the discount rate, and (v) $2.6 million in maintenance costs at Newman. These decreases were partially offset by increases of (i) $3.3 million primarily due to energy efficiency program costs previously offset by the related revenues prior to the adoption of ASU 2014-09, (ii) $2.8 million in outage costs at Newman Unit 4, and (iii) $1.0 million in maintenance costs at MPS.

Depreciation and amortization expense

Depreciation and amortization expense increased $1.5 million, or 6.4%, $4.1 million, or 5.7%, and $4.7 million, or 4.9%, for the three, nine and twelve months ended September 30, 2019, compared to the three, nine and twelve months ended September 30, 2018, primarily due to increased plant balances.

Taxes other than income taxes

Taxes other than income taxes increased $0.2 million, or 1.0%, $1.6 million, or 3.0%, and $1.4 million, or 1.9%, for the three, nine and twelve months ended September 30, 2019, compared to the three, nine and twelve months ended September 30, 2018, primarily due to the 1% increase in the City of El Paso franchise fee.

Other income (deductions)

Other income (deductions) decreased $8.6 million, or 49.4%, for the three months ended September 30, 2019, compared to the three months ended September 30, 2018, primarily due to (i) a $4.9 million decrease in realized and unrealized net gains on securities held in the NDT and (ii) $3.8 million of strategic transaction costs in the three months ended September 30, 2019, with no comparable costs in the three months ended September 30, 2018.

Other income (deductions) increased $6.8 million, or 19.0%, for the nine months ended September 30, 2019, compared to the nine months ended September 30, 2018, primarily due to a $15.7 million increase in realized and unrealized net gains on securities held in the NDT. This increase was partially offset by $9.5 million of strategic transaction costs in the nine months ended September 30, 2019, with no comparable costs in the nine months ended September 30, 2018.

Other income (deductions) decreased $16.1 million, or 35.3%, for the twelve months ended September 30, 2019, compared to the twelve months ended September 30, 2018, primarily due to (i) $9.5 million of strategic transaction costs in the twelve months ended September 30, 2019, with no comparable costs in the twelve months ended September 30, 2018 and (ii) a $8.4 million decrease in realized and unrealized net gains on securities held in the NDT.

Interest charges (credits)

Interest charges (credits) increased by $0.3 million, or 1.4% for the three months ended September 30, 2019, compared to the three months ended September 30, 2018, primarily due to additional borrowings under the Company's RCF, and an increase in the interest cost component of net periodic benefit cost of the Company's employee benefit plans. These increases were partially offset by the purchase in lieu of redemption of $63.5 million principal amount of 2009 Series A 7.25% PCBs on February 1, 2019 and $37.1 million principal amount of 2009 Series B 7.25% PCBs on April 1, 2019, and the subsequent reoffering and sale of the bonds on May 22, 2019 at the stated interest rate of 3.60% per annum.

Interest charges (credits) increased by $1.9 million, or 3.0%, for the nine months ended September 30, 2019, compared to the nine months ended September 30, 2018, primarily due to (i) interest expense on the $125.0 million aggregate principal amount of 4.22% Senior Notes due 2028 issued in June 2018, (ii) an increase in the interest cost component of net periodic benefit cost of the Company's employee benefit plans, and (iii) additional borrowings under the Company's RCF. These increases were partially offset by the purchase in lieu of redemption of $63.5 million principal amount of 2009 Series A 7.25% PCBs on February 1, 2019 and $37.1 million principal amount of 2009 Series B 7.25% PCBs on April 1, 2019, and the subsequent reoffering and sale of the bonds on May 22, 2019 at the stated interest rate of 3.60% per annum.

Interest charges (credits) increased by $2.6 million, or 3.1%, for the twelve months ended September 30, 2019, compared to the twelve months ended September 30, 2018, primarily due to (i) interest expense on the $125.0 million aggregate principal amount of 4.22% Senior Notes due 2028 issued in June 2018, (ii) an increase in the interest cost component of net periodic benefit cost of the Company's employee benefit plans, and (iii) additional borrowings under the Company's RCF. These increases were partially offset by (i) the purchase in lieu of redemption of $63.5 million principal amount of 2009 Series A 7.25% PCBs on February 1, 2019 and $37.1 million principal amount of 2009 Series B 7.25% PCBs on April 1, 2019, and the subsequent reoffering and sale of the bonds on May 22, 2019 at the stated interest rate of 3.60% per annum, and (ii) increased allowance for borrowed funds used during construction ("ABFUDC") as a result of higher average balances of construction work in progress ("CWIP") and an increase in the ABFUDC rate.

55

Income tax expense

Income tax expense increased $0.6 million, or 2.5%, for the three months ended September 30, 2019, compared to the three months ended September 30, 2018, primarily due to increases in pre-tax income and certain non-deductible strategic transaction costs. These increases were partially offset by decreases in state income taxes.

Income tax expense increased $2.0 million, or 6.7%, for the nine months ended September 30, 2019, compared to the nine months ended September 30, 2018, primarily due to (i) increases in pre-tax income, (ii) lower tax benefits of stock incentive plans, and (iii) certain non-deductible strategic transaction costs. These increases were partially offset by decreases in state income taxes.

Income tax expense decreased $3.0 million, or 9.6%, for the twelve months ended September 30, 2019, compared to the twelve months ended September 30, 2018, primarily due to (i) decreases in pre-tax income, (ii) the change in the federal income tax rate, and (iii) decreases in state income taxes. These decreases were partially offset by lower tax benefits of stock incentive plans and certain non-deductible strategic transaction costs.

New Accounting Standards

See Part I, Item 1, Financial Statements, Note A of Notes to Financial Statements for a discussion of new accounting standards adopted and to be adopted in the future.

Inflation

For the last several years, inflation has been relatively low and, therefore, has had minimal impact on our results of operations and financial condition.

56

Liquidity and Capital Resources

At September 30, 2019, our capital structure, including common stock equity, long-term debt, and short-term borrowings under our RCF, consisted of 45.3% common stock equity and 54.7% debt. As of September 30, 2019, we had a balance of $15.6 million in cash and cash equivalents. Based on current projections, we believe that we will have adequate liquidity through our current cash balances, cash from operations, available borrowings under the RCF and, if necessary, debt issuances in the capital markets or, after the closing of the Merger, an equity commitment from the Parent to meet all of our anticipated cash requirements for working capital and construction programs during the next twelve months. Prior to closing the Merger Agreement, the Company can incur additional indebtedness up to $200 million (excluding borrowings up to the existing borrowing capacity of the RCF), without written consent from the Parent; however, we cannot issue shares of common stock without the prior written consent of Parent. As discussed below, we have the necessary regulatory approvals to issue long-term debt and equity in the capital markets.

Our principal liquidity requirements in the near-term are expected to consist of capital expenditures to expand and support electric service obligations, expenditures for nuclear fuel inventory, interest payments on our indebtedness, cash dividend payments, operating expenses including fuel costs, maintenance costs, taxes, and strategic transaction costs related to the Merger.

Capital Requirements. During the nine months ended September 30, 2019, our primary capital requirements were related to the construction and purchase of electric utility plant, payment of common stock dividends and purchases of nuclear fuel. Capital expenditures for new electric utility plant were $160.0 million in the nine months ended September 30, 2019, compared to $171.4 million in the nine months ended September 30, 2018. Capital expenditures for 2019 are expected to be approximately $244 million. Capital requirements for purchases of nuclear fuel were $19.2 million in the nine months ended September 30, 2019 compared to $28.8 million in the nine months ended September 30, 2018.

On September 30, 2019, we paid a quarterly cash dividend of $0.385 per share, or $15.7 million, to shareholders of record as of the close of business on September 16, 2019. We paid a total of $46.0 million in cash dividends during the nine months ended September 30, 2019. On October 17, 2019, the Board of Directors declared a quarterly cash dividend of $0.385 per share, payable in cash on December 27, 2019, to shareholders of record as of the close of business on December 13. 2019. At the current dividend rate, we expect to pay cash dividends of approximately $61.7 million during 2019. Under the Merger Agreement, the Company may not declare or pay dividends or distributions on shares of common stock in an amount in excess of $0.385 per share for quarterly dividends declared before June 1, 2020 and $0.41 per share for quarterly dividends declared on or after June 1, 2020. Shareholders will continue to be entitled to receive any quarterly cash dividends, including a "stub period" dividend with respect to the period between the last quarterly dividend paid by the Company and the closing of the Merger.

We expect to continue to maintain a prudent level of liquidity and monitor market conditions for debt and equity securities. Our liquidity needs can fluctuate quickly based on fuel prices and other factors and we are continuing to make investments in new electric plant and other assets in order to reliably serve our customers.

Our cash requirements for federal and state income taxes vary from year to year based on taxable income, which is influenced by the timing of revenues and expenses recognized for income tax purposes. The following summary describes the major impacts of the TCJA on our liquidity.

The TCJA discontinued bonus depreciation for regulated utilities, which reduced tax deductions previously available to us beginning in 2018. The decrease in tax deductions results in the utilization of our net operating loss carryforwards ("NOL carryforwards") and other carryforwards approximately one year earlier than previously anticipated and is expected to result in higher income tax payments beginning in 2020, after the full utilization of NOL and other carryforwards. However, due to the lower federal corporate income tax rate enacted by the TCJA, our future federal corporate income tax payments will be made at the reduced rate of 21%. Due to NOL carryforwards, minimal tax payments are expected for 2019, which are mostly related to state income taxes.

The effect of the TCJA on our rates is beneficial to our customers. Following the enactment of the TCJA and the reduction of the federal corporate income tax rate, revenues collected from our customers in 2018 were reduced by $28.2 million, which negatively impacted our cash flows. A comparable amount is expected during 2019.

We continually evaluate our funding requirements related to our retirement plans, other post-retirement benefit plans and the NDT. During the nine months ended September 30, 2019, we contributed $8.8 million and $0.5 million to our retirement plans and other post-retirement benefits plan, respectively, and $1.6 million to the NDT. We are in compliance with the funding requirements of the federal government for our benefit plans. In addition, with respect to our nuclear plant decommissioning trust, we are in compliance with the funding requirements of the federal law and the ANPP Participation Agreement. We will continue to review our funding for these plans in order to meet our future obligations.

Capital Resources. Cash provided by operations, $191.0 million for the nine months ended September 30, 2019 and $221.5

57

million for the nine months ended September 30, 2018, is a significant source for funding capital requirements. A component of cash flows from operations is the change in net over-collection and under-collection of fuel revenues. The difference between fuel revenues collected and fuel expense incurred is deferred to be either refunded (over-recoveries) or surcharged (under-recoveries) to customers in the future. During the nine months ended September 30, 2019, we had fuel over-recoveries of $3.3 million compared to over-recoveries of fuel costs of $3.7 million during the nine months ended September 30, 2018. At September 30, 2019, we had a net fuel over-recovery balance of $14.4 million, including over-recoveries of $14.1 million in our Texas, $0.2 million in our New Mexico and $0.1 million in our FERC jurisdictions. On April 29, 2019, the Company filed a petition with the PUCT, which was assigned PUCT Docket No. 49482, requesting authority to implement, beginning on June 1, 2019, a four-month, interim fuel refund of $19.4 million in fuel cost over-recoveries, including interest, for the period from April 2016 through March 2019. On May 30, 2019, the Company's fuel refund credit was approved on an interim basis. The Company implemented the fuel refund in customer bills on June 1, 2019. On September 27, 2019, the PUCT issued a final order approving the fuel refund credits. The fuel refund was completed on September 30, 2019, with a total fuel refund of $20.1 million, including interest, returned to Texas customers. On September 13, 2019, the Company filed a request with the PUCT, which was assigned PUCT Docket No. 49960, to decrease our Texas fixed fuel factor by approximately 12.2% to reflect decreased fuel expenses primarily related to a decrease in the price of natural gas used to generate power. On September 25, 2019, our fixed fuel factor was approved by the PUCT on an interim basis effective for the first billing cycle of the October 2019 billing month. The Texas fixed fuel factor was determined to be final on October 15, 2019, and will continue until changed by the PUCT.

We received approval from the NMPRC on October 7, 2015, to guarantee the issuance of up to $65.0 million of long-term debt by the RGRT to finance future purchases of nuclear fuel and to refinance existing nuclear fuel debt obligations. We received additional approval from the NMPRC on October 4, 2017, to amend and extend the RCF, issue up to $350.0 million in long-term debt and to redeem and refinance the $63.5 million aggregate principal amount of 2009 Series A 7.25% PCBs and the $37.1 million aggregate principal amount of 2009 Series B 7.25% PCBs. The NMPRC approval to issue up to $350.0 million in long-term debt supersedes its prior approval. We received approval from the FERC on October 31, 2017, to issue up to $350.0 million in long-term debt, to guarantee the issuance of up to $65.0 million of long-term debt by the RGRT, and to continue to utilize our existing RCF with the ability to amend and extend the RCF at a future date, and to redeem, refinance and/or replace the 2009 Series A 7.25% PCBs and 2009 Series B 7.25% PCBs with debt of equal face value. The authorization approved by the FERC was effective from November 15, 2017 through November 14, 2019, and superseded its prior approvals. On March 27, 2019, the NMPRC issued a final order approving the Company's request to issue shares of common stock, including the reissuance of treasury shares, in an amount up to $200.0 million in one or more transactions. On April 18, 2019, the Company received approval from the FERC to issue shares of common stock, including the reissuance of treasury shares, in an amount up to $200.0 million in one or more transactions; to utilize the existing RCF for short-term borrowings not to exceed $400.0 million at any one time; to issue up to $225.0 million in new long-term debt; and to remarket the $63.5 million aggregate principal amount of 2009 Series A 7.25% PCBs and the $37.1 million aggregate principal amount of 2009 Series B 7.25% PCBs in the form of replacement bonds or senior notes of equivalent value, not to exceed $100.6 million. The authorization approved by the FERC is effective from April 18, 2019 through April 18, 2021, and supersedes its prior approvals.

Under these authorizations, on June 28, 2018, the Company issued $125.0 million in aggregate principal amount of 4.22% Senior Notes due August 15, 2028, and guaranteed the issuance by the RGRT of $65.0 million in aggregate principal amount of 4.07% Senior Guaranteed Notes due August 15, 2025. The net proceeds from the sale of these senior notes were used to repay outstanding short-term borrowings under the RCF, which included borrowings made for working capital, general corporate purposes and the purchase of nuclear fuel. Also, under these authorizations, on September 13, 2018, the Company and RGRT entered into a third amended and restated credit agreement where we have available a $350.0 million RCF with a term ending on September 13, 2023. We may increase the RCF by up to $50.0 million (to a total of $400.0 million) during the term of the RCF, upon the satisfaction of certain conditions more fully set forth in the agreement, including obtaining commitments from lenders or third party financial institutions. In addition, we may extend the maturity date of the RCF up to two times, in each case for an additional one-year period upon the satisfaction of certain conditions. On February 1, 2019, the Company purchased in lieu of redemption all of the 2009 Series A 7.25% PCBs utilizing funds borrowed under the RCF. On April 1, 2019, the Company purchased in lieu of redemption all of the 2009 Series B 7.25% PCBs utilizing funds borrowed under the RCF. On May 22, 2019, the Company reoffered and sold $63.5 million aggregate principal amount of 2009 Series A 7.25% PCBs and $37.1 million aggregate principal amount of 2009 Series B 7.25% PCBs with a fixed interest rate of 3.60% per annum until the bonds mature on February 1, 2040, and April 1, 2040, respectively. The bonds are subject to optional redemption at a redemption price of par on or after June 1, 2029. Proceeds from the remarketing of the bonds were primarily used to repay outstanding short-term borrowings under the RCF.

The Merger would constitute a "Change in Control" under the RCF and the consummation of the Merger would result in an event of default under the RCF. On and subject to the terms and conditions of the Merger Agreement, the Company requested that the lenders under the RCF consent to the Merger and waive any default or event of default that would occur as a result of the Merger. On August 9, 2019, the lenders agreed to such consent and waiver.

58

We maintain the RCF for working capital and general corporate purposes and financing of nuclear fuel through the RGRT. The RGRT, the trust through which we finance our portion of nuclear fuel for Palo Verde, is consolidated in our financial statements. The total amount borrowed for nuclear fuel by the RGRT, excluding debt issuance costs, was $132.8 million at September 30, 2019, of which $22.8 million had been borrowed under the RCF, and $110.0 million was borrowed through the issuance of senior notes. Borrowings by the RGRT for nuclear fuel, excluding debt issuance costs, were $129.4 million as of September 30, 2018, of which $19.4 million had been borrowed under the RCF and $110.0 million was borrowed through the issuance of senior notes. Interest costs on borrowings to finance nuclear fuel are accumulated by the RGRT and charged to us as fuel is consumed and recovered through fuel recovery charges. At September 30, 2019, $77.0 million was outstanding under the RCF for working capital and general corporate purposes. At September 30, 2018, no borrowings were outstanding under the RCF for working capital and general corporate purposes. Total aggregate borrowings under the RCF at September 30, 2019, were $99.8 million with an additional $250.0 million available to borrow.

Off-Balance Sheet Arrangements

We have no off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.

Item 4. Controls and Procedures

Evaluation of disclosure controls and procedures. Under the supervision and with the participation of our management, including our chief executive officer and our chief financial officer, we conducted an evaluation pursuant to Rule 13a-15(b) under the Exchange Act of our disclosure controls and procedures as defined in Rule 13a-15(e) under the Exchange Act. Based on that evaluation, our chief executive officer and our chief financial officer concluded that, as of September 30, 2019, our disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed in the Company's reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms and such information is accumulated and communicated to management, including our chief executive officer and our chief financial officer, as appropriate to allow timely decisions regarding disclosure.

Changes in internal control over financial reporting. In August 2019, the Company replaced its existing human resource and payroll management system. Throughout the system implementation the Company considered system impact on internal controls and procedures and concluded that the implementation resulted in no material changes in our internal controls over financial reporting. In addition, there were no changes in our internal control over financial reporting in connection with the evaluation required by paragraph (d) of the Exchange Act Rules 13a-15 or 15d-15, that occurred during the quarter ended September 30, 2019, that materially affected, or that were reasonably likely to materially affect, our internal control over financial reporting.

EXHIBIT 10.01

EL PASO ELECTRIC COMPANY

AMENDED AND RESTATED 2007 LONG-TERM INCENTIVE PLAN

RESTRICTED STOCK AWARD AGREEMENT

(FOR EMPLOYEES; HARD COPY ACCEPTANCE)

El Paso Electric Company, a Texas corporation (the "Company"), has granted to the Participant, under the El Paso Electric Company Amended and Restated 2007 Long-Term Incentive Plan (the “Plan”), a restricted stock award (the "Award") of a number of Shares, upon and subject to the restrictions, terms and conditions set forth below. Capitalized terms not defined herein shall have the meanings specified in the Plan.

1. Award; Vest Date; Acceptance of Award Agreement.

(a)This Award covers 27,624 Shares granted to Mary E. Kipp (the “Participant”) as of July 31, 2019 (the “Award Date”). Subject to the Participant’s compliance with the terms and conditions of that certain Separation Agreement between the Company and the Participant, dated as of July 1, 2019, the Shares will vest immediately prior to the closing of the merger (the “Merger”) contemplated by that certain Agreement and Plan of Merger, by and among Sun Jupiter Holdings LLC (“Jupiter”), the Company and Sun Merger Sub Inc., a wholly-owned subsidiary of Jupiter, entered into on June 1, 2019 (as it may be amended from time to time, the “Merger Agreement”). The date on which this vesting occurs is the Vest Date. In the event the Merger Agreement is terminated without the closing of the Merger, the Restricted Stock Award will be forfeited, and there will be no Vest Date.

(b)The Award shall be null and void unless the Participant shall accept this Award Agreement by executing it in the space provided below and returning it to the Company. As soon as practicable after the Participant has executed this Award Agreement, shares will be allocated to the Participant's account in book‑entry form in a manner that effectively prevents transfers during the Restriction Period (as defined below).

2. Rights as a Shareholder. The Participant shall have the right to vote the Shares subject to the Award and to receive dividends and other distributions thereon; provided, however, that a dividend or other distribution with respect to Shares (including, without limitation, a stock dividend or stock split), other than a regular cash dividend, shall be subject to the same restrictions as the Shares with respect to which such dividend or other distribution was made.

3. Removal of Restrictions. At the termination of the Restriction Period, the Company shall cause any restriction of transfer to be removed from the Participant’s account in book‑entry form with respect to the Shares for which restrictions have lapsed pursuant to Section 4 hereof and subject to Section 5.2.

1

4. “Restriction Period” and Vesting. The restrictions on the applicable portion of the Award shall lapse on the “Vest Date” specified in Section 1, and the period between the Award Date and the Vest Date is referred to as the “Restriction Period.”

5.Additional Terms and Conditions of Award.

5.1. Non-transferability of Award. During the Restriction Period, the Shares subject to the Award as to which restrictions remain in effect may not be sold, transferred, assigned, pledged, hypothecated, encumbered or otherwise disposed of (whether by operation of law or otherwise) or be subject to execution, attachment or similar process. Upon any attempt to so sell, transfer, assign, pledge, hypothecate or encumber, or otherwise dispose of such shares, the Award shall immediately become null and void.

5.2.Withholding Taxes. Unless the Participant makes arrangements satisfactory to the Company to pay to the Company the required statutory tax under all applicable federal, state, local or other laws or regulations (the "Required Tax Payments") in cash, the Participant acknowledges that the Company will withhold applicable taxes at the minimum statutory rate from the Shares and dividends otherwise to be delivered to the Participant pursuant to the Award by withholding a number of whole Shares having a Fair Market Value (or in the case of dividends, cash), determined as of the date the withholding obligation arises, equal to the Required Tax Payments (with any fractional Share rounded up to the nearest whole Share). No certificate representing a Share shall be delivered until the Required Tax Payments have been satisfied in full. To the extent allowed under the Plan and with the consent of the Committee, the Participant may elect to have the Company withhold from Shares or dividends otherwise to be delivered to the Participant pursuant to the Award a number of whole Shares having a Fair Market Value (or in the case of dividends, cash) equal to the product of up to the maximum statutory marginal rate that could be applicable to the Participant and the Fair Market Value of the Shares or cash otherwise to be delivered to the Participant, as applicable.

5.3. Award Agreement Subject to the Plan. This Award Agreement is subject to the provisions of the Plan and shall be interpreted in accordance therewith. The Participant hereby acknowledges receipt of a copy of the Plan. To the extent that any provision of this Award Agreement conflicts with the express terms of the Plan, it is hereby acknowledged and agreed that the terms of the Plan shall control and, if necessary, the applicable provisions of this Award Agreement shall be hereby deemed amended so as to carry out the purpose and intent of the Plan.

5.4 Severability. In the event any provision of this Award Agreement shall be held illegal or invalid for any reason, the illegality or invalidity shall not affect the remaining parts of this Award Agreement, and this Award Agreement shall be construed and enforced as if the illegal or invalid provision had not been included.

5.5 Compliance with Recoupment Policy. Any amounts payable, paid, or distributed under this Award Agreement are subject to the recoupment policy of the Company as in effect from time to time.

2

6.Miscellaneous Provisions.

6.1. Successors. This Award Agreement shall be binding upon and inure to the benefit of any successor or successors of the Company and any person or persons who shall acquire any rights hereunder in accordance with this Award Agreement or the Plan.

6.2. Notices. All notices, requests or other communications provided for in this Award Agreement shall be made, if to the Company, to El Paso Electric Company, Stanton Tower, 100 N. Stanton, El Paso, Texas 79901, Attention: Corporate Secretary, and if to the Participant, to Participant’s Name at the last address provided to the Company. All notices, requests or other communications provided for in this Award Agreement shall be made in writing either (a) by personal delivery to the party entitled thereto, (b) by facsimile with confirmation of receipt, (c) by mailing in the United States mails to the last known address of the party entitled thereto or (d) by express courier service. The notice, request or other communication shall be deemed to be received upon personal delivery, upon confirmation of receipt of facsimile transmission, or upon receipt by the party entitled thereto if by United States mail or express courier service; provided, however, that if a notice, request or other communication is not received during regular business hours, it shall be deemed to be received on the next succeeding business day of the Company.

6.3. Counterparts. This Award Agreement may be executed in two counterparts, each of which shall be deemed an original and both of which shall constitute one and the same instrument together, shall constitute one and the same instrument.

Spent Fuel and Waste Disposal. Pursuant to the Nuclear Waste Policy Act of 1982, as amended in 1987, the U.S. Department of Energy ("DOE") is legally obligated to accept and dispose of all spent nuclear fuel and other high-level radioactive waste generated by all domestic power reactors by 1998. The DOE's obligations are reflected in a contract for Disposal of Spent Nuclear Fuel and/or High Level Radioactive Waste with each nuclear power plant. The DOE failed to begin accepting spent nuclear fuel by 1998. Pursuant to the terms of the August 18, 2014 settlement agreement, and as amended with the DOE, Arizona Public Service Company ("APS") files annual claims for the period July 1 of the then-previous year to June 30 of the then-current year on behalf of itself and those utilities that share in power and energy entitlements, and bear certain allocated costs, with respect to Palo Verde Generating Station ("Palo Verde") pursuant to the Arizona Nuclear Power Project Participation Agreement dated August 23, 1973, as amended ("ANPP Participation Agreement"). The settlement agreement, as amended, provides APS with a method for submitting claims and receiving recovery for costs incurred through December 31, 2016, which has been extended to December 31, 2019.

On October 31, 2019, APS filed a $16.0 million claim for the period July 1, 2018 through June 30, 2019. The Company's share of this claim is approximately $2.5 million. This claim is pending DOE review. The majority of the reimbursement received by the Company is expected to be credited to customers through the applicable fuel adjustment clauses.

These condensed financial statements should be read in conjunction with the financial statements and notes thereto in the Annual Report of El Paso Electric Company (the "Company") on Form 10-K for the fiscal year ended December 31, 2018 ("2018 Form 10-K"). Capitalized terms used in this report and not defined herein have the meaning ascribed to such terms in the 2018 Form 10-K. In the opinion of the Company’s management, the accompanying financial statements contain all adjustments necessary to present fairly the financial position of the Company at September 30, 2019 and December 31, 2018; the results of its operations and comprehensive operations for the three, nine and twelve months ended September 30, 2019 and 2018; changes in common stock equity for the three and nine months ended September 30, 2019 and 2018; and its cash flows for the nine months ended September 30, 2019 and 2018. The results of operations, comprehensive operations and the changes in common stock equity for the three and nine months ended September 30, 2019 and 2018, and the cash flows for the nine months ended September 30, 2019 and 2018, are not necessarily indicative of the results to be expected for the full calendar year.

Pursuant to the rules and regulations of the United States ("U.S.") Securities and Exchange Commission ("SEC"), certain financial information has been condensed and certain footnote disclosures have been omitted. Such information and disclosures are normally included in financial statements prepared in accordance with U.S. Generally Accepted Accounting Principles ("GAAP").

Use of Estimates. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The Company evaluates its estimates on an on-going basis, including those related to depreciation, unbilled revenue, income taxes, fuel costs, pension and other post-retirement obligations and asset retirement obligations. Actual results could differ from those estimates.

Operating Revenues. The Company accrues revenues for services rendered, including unbilled electric service revenues. The Company recognizes revenue associated with contracts with customers when performance obligations under the terms of the contract with the customer are satisfied. Revenue is measured as the amount of consideration the Company receives in exchange for transferring goods or providing services to the customer. Taxes collected concurrently with revenue producing activities are excluded from revenue. Unbilled revenues are recorded for estimated amounts of energy delivered in the period following the customer's last billing cycle to the end of the reporting period. Unbilled revenues are estimated based on monthly generation volumes and by applying an average revenue/kilowatt-hour ("kWh") to the number of estimated kWhs delivered but not billed. Accounts receivable included accrued unbilled revenues of $33.3 million at September 30, 2019 and $21.6 million at December 31, 2018.

The Company’s Texas retail customers are billed under base rates and a fixed fuel factor approved by the Public Utility Commission of Texas ("PUCT"). The Company’s New Mexico retail customers are billed under base rates and a fuel adjustment clause that is adjusted monthly, as approved by the New Mexico Public Regulation Commission ("NMPRC"). The Company's Federal Energy Regulatory Commission ("FERC") sales for resale customers are billed under formula base rates and fuel factors and a fuel adjustment clause that is adjusted monthly. The Company’s recovery of fuel and purchased power expenses is subject to periodic reconciliations of actual fuel and purchased power expenses incurred to actual fuel revenues collected. The difference between fuel and purchased power expenses incurred and fuel revenues charged to customers is reflected as over/under-collection of fuel revenues, which is included in regulatory liabilities/assets - current in the balance sheets. See Part I, Item 1, Financial Statements, Note D of Notes to Financial Statements for further discussion.

Leases. The Company determines if an arrangement contains a lease and the classification of that lease at inception. Operating lease right-of-use (“ROU”) assets represent the Company’s right to use an underlying asset for the lease term and operating lease liabilities represent the obligation to make payments under the lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the estimated present value of the minimum lease payments over the lease term. In determining lease terms, the Company considers any options to extend or terminate the lease that are reasonably certain of being exercised. As the Company’s leases do not include an implicit rate, the Company uses an estimated incremental borrowing rate, at lease commencement, to determine the present value of the future lease payments. In calculating the incremental borrowing rate, the Company takes into consideration recent debt issuances and other data for instruments with similar characteristics. The Company’s lease agreements do not contain residual value guarantees or restrictive covenants. For leases with lease and non-lease components, the Company has elected to account for the consideration as a single lease component. The Company has also elected not to record leases with a term of 12 months or less on the balance sheets. The operating lease ROU assets are included as part of electric plant in service and lease liabilities are included as part of current and non-current liabilities in the Company’s balance sheets.

Depreciation. The Company routinely evaluates the depreciable service lives, cost of removal and salvage values of its property, plant and equipment. Depreciation is provided on a straight-line basis over the estimated remaining lives of the assets (ranging in average from 5 to 48 years). When property subject to composite depreciation is retired or otherwise disposed of in the normal course of business, its cost together with the cost of removal, less salvage is charged to accumulated depreciation. For other property dispositions, the applicable cost and accumulated depreciation is removed from the balance sheet accounts and a gain or loss is recognized.

New Accounting Standards Adopted

In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-02, Leases (Topic 842), to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and requiring qualitative and quantitative disclosures on leasing agreements. ASU 2016-02 maintains a distinction between finance leases and operating leases similar to the distinction under previous lease guidance for capital leases and operating leases. Effective January 1, 2019, the Company adopted ASU 2016-02 using the modified retrospective method, applying the transition provisions to the beginning of the period of adoption rather than to the earliest comparative period presented, which continues to be reported in accordance with previous lease guidance, Accounting Standards Codification Topic 840. The Company adopted the package of practical expedients, which does not require the Company to reassess: (i) whether an arrangement contained a lease, (ii) lease classification for any expired or existing leases, and (iii) initial direct costs for any expired or existing leases. The Company also adopted the practical expedient related to land easements, which allowed carry forward accounting treatment for existing land easements. The most significant impact of adopting ASU 2016-02, as of January 1, 2019, was the recording of approximately $6.3 million of operating lease liabilities and related ROU assets with no cumulative effect adjustment to retained earnings. The Company anticipates the ongoing impact of the new standard to be immaterial to net income and cash flows. See Part I, Item 1, Financial Statements, Note I of Notes to Financial Statements for further discussion.

In February 2018, the FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220), as a result of concerns raised due to the federal law commonly referred to as the Tax Cuts and Jobs Act of 2017 ("TCJA"). More specifically, because the remeasurement of deferred taxes due to the change in the federal corporate income tax rate is required to be included in income from continuing operations, the tax effects of items within accumulated other comprehensive income ("AOCI") (referred to as stranded tax effects) do not reflect the appropriate tax rate. ASU 2018-02 allows companies an election to reclassify stranded taxes from AOCI to retained earnings. The amount of the reclassification would be the difference between the historical federal corporate income tax rate of 35% and the newly enacted 21% federal corporate income tax rate, which approximates $7.2 million. The provisions of ASU 2018-02 are effective for fiscal years and interim periods within that reporting period beginning after December 15, 2018. The Company adopted ASU 2018-02 on January 1, 2019, and has elected to not reclassify stranded taxes from AOCI to retained earnings.

New Accounting Standards to be Adopted in the Future

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326). ASU 2016-13 changes how companies measure and recognize credit impairment for many financial assets. The new expected credit loss model will require companies to immediately recognize an estimate of credit losses expected to occur over the remaining life of the financial assets that are in the scope of the standard. ASU 2016-13 will be required for reporting periods beginning after December 15, 2019. ASU 2016-13 will be applied in a modified retrospective approach through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is implemented. The Company is currently in the process of evaluating the impact of the new standard, which includes continuing to monitor activities of the FASB, including the impact of ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments and ASU 2019-05, Financial Instruments - Credit Losses (Topic 326): Targeted Transition Relief.

Agreement and Plan of Merger

Agreement and Plan of Merger

On June 1, 2019, the Company entered into the Merger Agreement, by and among the Company, Parent, and Merger Sub. Pursuant to the Merger Agreement, on and subject to the terms and conditions set forth therein, Merger Sub will merge with and into the Company, with the Company continuing as the surviving corporation in the Merger and becoming a wholly owned subsidiary of Parent. Parent and Merger Sub are affiliates of IIF.

On and subject to the terms and conditions set forth in the Merger Agreement, upon the closing of the Merger, each share of common stock of the Company shall be cancelled and converted into the right to receive $68.25 in cash, without interest (the "Merger Consideration").

The Company, Parent and Merger Sub each have made various representations, warranties and covenants in the Merger Agreement. Among other things, the Company has agreed, subject to certain exceptions, to conduct its business in the ordinary course, consistent with past practice, from the date of the Merger Agreement until the closing of the Merger, and not to take certain actions prior to the closing of the Merger without the prior written consent of Parent (which consent shall not be unreasonably withheld, conditioned or delayed). The Company has made certain additional customary covenants, including, subject to certain exceptions: (1) to cause a meeting of the Company’s shareholders to be held to consider approval of the Merger Agreement, (2) not to solicit proposals relating to alternative business combination transactions and not to participate in discussions concerning, or furnish information in connection with, alternative business combination transactions and (3) not to withdraw its recommendation to the Company’s shareholders regarding the Merger. In addition, subject to the terms of the Merger Agreement, the Company, Parent and Merger Sub are required to use reasonable best efforts to obtain all required regulatory approvals, which will include clearance under federal antitrust laws and certain approvals by federal and state regulatory bodies, subject to certain exceptions, including that such efforts not result in a Burdensome Condition (as defined in the Merger Agreement). Parent has obtained equity and debt financing commitments for the transactions contemplated by the Merger Agreement, the aggregate proceeds of which will be sufficient to consummate the Merger and the other transactions contemplated by the Merger Agreement, including payment of the aggregate Merger Consideration.

Consummation of the Merger is subject to various conditions, including: (1) approval of the shareholders of the Company, (2) expiration or termination of the applicable HSR Act waiting period, (3) receipt of all required regulatory and statutory approvals without the imposition of a Burdensome Condition, (4) absence of any law or order prohibiting the consummation of the Merger and (5) other customary closing conditions, including (a) subject to materiality qualifiers, the accuracy of each party's representations

and warranties, (b) each party's compliance in all material respects with its obligations and covenants under the Merger Agreement and (c) the absence of a material adverse effect with respect to the Company.

The Merger Agreement contains certain termination rights for both the Company and Parent, including if the Merger is not consummated by June 1, 2020 (subject to extension for an additional three months if all of the conditions to closing, other than the conditions related to obtaining regulatory approvals, have been satisfied). The Merger Agreement also provides for certain termination rights for each of the Company and Parent, and provides that, upon termination of the Merger Agreement under certain specified circumstances, Parent would be required to pay a termination fee of $170 million to the Company, and under other specified circumstances, the Company would be required to pay Parent a termination fee of $85 million.

On August 2, 2019, the Company filed a definitive proxy statement with the SEC in connection with the Merger. As of November 7, 2019, three purported Company shareholders have filed lawsuits alleging violations under the federal securities laws, two in the U.S. District Court for the Southern District of New York and one in the U.S. District Court for the District of Delaware, challenging the adequacy of the disclosures made in the Company's proxy statement in connection with the Merger as discussed in Part I, Item 1, Financial Statements, Note J of Notes to Financial Statements.

On August 13, 2019, the Company, Parent and IIF US Holdings 2 LP, an affiliate of IIF, as applicable, filed (1) the joint report and application for regulatory approvals with the PUCT requesting approval of the Merger pursuant to the PURA, (2) the joint application for regulatory approvals with the NMPRC requesting approval of the Merger pursuant to the NMPUA and NMPRC Rule 450, (3) the joint application requesting approval of the Merger with the FERC under Section 203 of the Federal Power Act and (4) the joint application for regulatory approval for the indirect transfer of the Company’s NRC licenses to Parent from the NRC under the Atomic Energy Act of 1954. In addition, on August 13, 2019, the Company and Parent sought the authorization of the FCC to assign or transfer control of the Company’s FCC licenses.

On August 16, 2019, the Company and Parent filed the notification and report form with the Antitrust Division of the Department of Justice and the FTC under the HSR Act. On September 3, 2019, the Company and Parent received notice from the FTC granting early termination of the waiting period under the HSR Act. 

Under the Merger Agreement, the consent to the Merger by the City of El Paso under its franchise agreement with the Company is a condition to the closing of the Merger. Under the franchise agreement, if the City of El Paso does not grant its consent to the Merger, the franchise agreement would terminate upon the closing of the Merger. On September 20, 2019, the Company submitted the franchise agreement assignment application to the City of El Paso.

At a special meeting of the Company's shareholders held on September 19, 2019, the Company’s shareholders approved the Merger Agreement and the transactions contemplated thereby, including the Merger, and the compensation that will or may become payable by the Company to its named executive officers in connection with the Merger.

Subject to receipt of remaining approvals and satisfaction of the other closing conditions, the Company anticipates that the closing of the Merger will occur in the first half of 2020.

For more information regarding the terms of the Merger, including a copy of the Merger Agreement, see the Company's Current Report on Form 8-K filed with the SEC on June 3, 2019, and its definitive proxy statement relating to the special meeting of shareholders filed with the SEC on August 2, 2019.

Litigation Matters Disclosure

Litigation

The Company is involved in various legal, environmental, tax and regulatory proceedings before various courts, regulatory commissions and governmental agencies regarding matters arising in the ordinary course of business. In many of these matters, the Company has excess casualty liability insurance that covers the various claims, actions and complaints. The Company regularly analyzes current information and, as necessary, makes provisions in its financial statements for probable liabilities for the eventual disposition of these matters. While the outcome of these matters cannot be predicted with certainty, based upon a review of the matters and applicable insurance coverage, the Company believes that none of these matters will have a material adverse effect on the financial position, results of operations or cash flows of the Company. The Company expenses legal costs, including expenses related to loss contingencies, as they are incurred.

See Part I, Item 1, Financial Statements, Notes D and H of Notes to Financial Statements above and Part II, Item 8, Financial Statements and Supplementary Data, Notes D and L of the Notes to Financial Statements in the 2018 Form 10-K for discussion of the effects of government legislation and regulation on the Company.

Litigation Related to the Merger. As of November 7, 2019, three purported Company shareholders have filed lawsuits under the federal securities laws, two in the U.S. District Court for the Southern District of New York and one in the U.S. District Court for the District of Delaware, challenging the adequacy of the disclosures made in the Company’s preliminary proxy statement in connection with the Merger. These cases are captioned Stein v. El Paso Electric Company., et al., Case No. 1:19-cv-06703 (the “Stein Action”), Rosenblatt v. El Paso Electric Company., et al., Case No. 1:19-cv-01367-UNA (the “Rosenblatt Action”), and Gorski v. El Paso Electric Company., et. al., Case No. 1:19-cv-07211 (the “Gorski Action”), respectively. The Stein Action, filed on July 18, 2019, the Rosenblatt Action, filed on July 23, 2019, and the Gorski Action, filed on August 1, 2019, are asserted on behalf of putative classes of Company shareholders.

All three actions allege violations of Sections 14(a) and 20(a) of the Securities and Exchange Act of 1934, as amended (the "Exchange Act") and Rule 14a-9 promulgated thereunder based on various alleged omissions of material information from the preliminary proxy statement. The Stein Action names as defendants the Company and each of our directors, individually, and seeks to enjoin the Merger (or, in the alternative, rescission or an award of rescissory damages in the event the Merger is completed), damages, and an award of costs and attorneys’ and expert fees. The Rosenblatt Action names as defendants the Company and each of our directors, individually, and seeks to enjoin the Merger (or, in the alternative, rescission or an award of rescissory damages in the event the Merger is completed), to compel our directors to issue a revised proxy statement, a declaration that the defendants violated Sections 14(a) and 20(a) of the Exchange Act and Rule 14a-9 promulgated thereunder, and an award of costs and attorneys’ and expert fees. The Gorski Action also names as defendants the Company and each of our directors, individually, and seeks to enjoin the Merger (or, in the alternative, rescission or an award of rescissory damages in the event the Merger is completed), to compel our directors to issue a revised proxy statement, a declaration that the defendants violated Sections 14(a) and 20(a) of the Exchange Act and Rule 14a-9 promulgated thereunder, and an award of costs and attorneys’ and expert fees.

The Company believes that these complaints are without merit, and while the Company believes that the disclosures set forth in the proxy statement complied fully with applicable law, to moot plaintiffs’ disclosure claims, to avoid nuisance, potential expense and delay, and to provide additional information to the Company’s shareholders, the Company voluntarily supplemented the proxy statement with additional disclosure in a Current Report on Form 8-K filed by the Company with the SEC on September 9, 2019. While the outcome of these matters cannot be predicted with certainty, based upon a review of the matters and applicable insurance coverage, the Company believes that none of these matters will have a material adverse effect on the financial position, results of operations or cash flows of the Company. The Company expenses legal costs, including expenses related to loss contingencies, as they are incurred.

Fair Value Disclosures [Abstract]

Financial Instruments and Investments

Financial Instruments and Investments

The FASB guidance requires the Company to disclose estimated fair values for its financial instruments. The Company has determined that cash and temporary investments, investment in debt securities, accounts receivable, decommissioning trust funds, long-term debt, short-term borrowings under the RCF, accounts payable and customer deposits meet the definition of financial instruments. The carrying amounts of cash and temporary investments, accounts receivable, accounts payable and customer deposits approximate fair value because of the short maturity of these items. Investments in debt securities and decommissioning trust funds are carried at estimated fair value.

Long-Term Debt and Short-Term Borrowings Under the RCF. The fair values of the Company's long-term debt and short-term borrowings under the RCF are based on estimated market prices for similar issues and are presented below (in thousands): 

	September 30, 2019				December 31, 2018
	Carrying Amount		Estimated Fair Value		Carrying Amount		Estimated Fair Value
Pollution Control Bonds (1)	$	157,947	$	167,977	$	157,769	$	161,917
Senior Notes	1,118,255		1,393,650		1,117,943		1,244,310
RGRT Senior Notes (2)	109,589		114,925		109,507		111,440
RCF (2)	99,826		99,826		49,207		49,207
Total	$	1,485,617	$	1,776,378	$	1,434,426	$	1,566,874

_______________ 

(1) On February 1, 2019 and April 1, 2019, the Company purchased in lieu of redemption the 2009 Series A 7.25% PCBs with an aggregate principal amount of $63.5 million and the 2009 Series B 7.25% PCBs with an aggregate principal amount of $37.1 million, respectively, utilizing funds borrowed under the RCF. On May 22, 2019, the Company reoffered and sold $63.5 million aggregate principal amount of 2009 Series A 7.25% PCBs and $37.1 million aggregate principal amount of 2009 Series B 7.25% PCBs with a fixed interest rate of 3.60% per annum until the bonds mature on February 1, 2040 and April 1, 2040, respectively. See Part I, Item 1, Financial Statements, Note M of Notes to Financial Statements for further discussion.

(2)

Nuclear fuel financing, as of September 30, 2019 and December 31, 2018, is funded through $110 million RGRT Senior Notes and $22.8 million and $26.2 million, respectively, under the RCF. As of September 30, 2019, $77.0 million was outstanding under the RCF for working capital and general corporate purposes. As of December 31, 2018, $23.0 million, was outstanding under the RCF for working capital or general corporate purposes. The interest rate on the Company's borrowings under the RCF is reset throughout the quarter reflecting current market rates. Consequently, the carrying value approximates fair value. See Part I, Item 1, Financial Statements, Note M of Notes to Financial Statements for further discussion.

Marketable Securities. The Company's marketable securities, included in decommissioning trust funds in the balance sheets, are reported at fair value which was $311.7 million and $276.9 million at September 30, 2019 and December 31, 2018, respectively. The investments in the Company's Palo Verde nuclear decommissioning trust funds ("NDT") are classified as equity securities and temporary cash and cash equivalents restricted solely for investment in the NDT. These investments are recorded at their estimated fair value in accordance with FASB guidance for certain investments in equity securities. On January 1, 2018, the Company adopted ASU 2016-01, Financial Instruments - Overall, which eliminates the requirements to classify investments in equity securities with readily determinable fair values as trading or available for sale and requires entities to recognize changes in fair value for these securities in net income as reported in the Statements of Operations. ASU 2016-01 requires a modified-retrospective approach and therefore, comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods.

During September 2019, the Company sold all of the fixed income securities classified as available for sale held in the NDT which approximated 450 individual securities. The proceeds were reinvested in three exchange traded funds that hold similar securities. The exchange traded funds meet the definition of equity securities with readily determinable fair values and therefore are not classified as available for sale as of September 30, 2019. Furthermore, changes in the fair value of these exchange traded funds will be recorded in net income as reported in the Statement of Operations, as required by ASU 2016-01.

Prior to September 30, 2019, the reported fair values included gross unrealized losses on securities classified as available for sale whose impairment the Company had deemed to be temporary. The table below presents the gross unrealized losses and the fair value of these securities as of December 31, 2018, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position (in thousands): 

	December 31, 2018

_________________

(1) Includes 156 securities.

Prior to the sale of all the Company's fixed income securities classified as available for sale, the Company monitored the length of time such securities traded below their cost basis along with the amount and percentage of the unrealized loss in determining if a decline in fair value below recorded cost was considered to be other than temporary. In accordance with the FASB guidance, such impairment losses were recognized in net income, and a lower cost basis was established for these securities. For the three, nine and twelve months ended September 30, 2019 and 2018, the Company did not recognize any other than temporary impairment losses on its available for sale securities.

Investments categorized as available for sale securities also included gross unrealized gains which had not been recognized in the Company's net income prior to September 30, 2019. The table below presents the unrecognized gross unrealized gains and the fair value of these securities, aggregated by investment category as of December 31, 2018 (in thousands):

The Company's available for sale securities in the NDT were sold from time to time and the Company used the specific identification basis to determine the amount to reclassify from AOCI into net income. The proceeds from the sale of these securities during the three, nine and twelve months ended September 30, 2019 and 2018, and the related effects on pre-tax income are as follows (in thousands):

Net gains (losses) included in pre-tax income	$	3,202		$	(443	)	$	2,232		$	(1,108	)	$	1,895		$	396

Upon the adoption of ASU 2016-01, Financial Instruments - Overall, on January 1, 2018, the Company records, on a modified-retrospective basis, changes in fair market value for equity securities held in the NDT in the Statements of Operations. The unrealized gains and losses recognized during the three and nine months ended September 30, 2019 and 2018, and related effects on pre-tax income are as follows (in thousands):

	Three Months Ended				Nine Months Ended
	September 30,				September 30,
	2019		2018		2019		2018
Net gains recognized on equity securities	$	1,010	$	9,533	$	23,195	$	10,791
Less: Net gains recognized on equity securities sold	136		3,005		422		7,061
Unrealized gains recognized on equity securities still held at reporting date	$	874	$	6,528	$	22,773	$	3,730

Fair Value Measurements. The FASB guidance requires the Company to provide expanded quantitative disclosures for financial assets and liabilities recorded on the balance sheet at fair value. Financial assets carried at fair value include the Company's decommissioning trust investments and investments in debt securities which are included in deferred charges and other assets on the Balance Sheets. The Company has no liabilities that are measured at fair value on a recurring basis. The FASB guidance establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three levels as follows:

• Level 1 – Observable inputs that reflect quoted market prices for identical assets and liabilities in active markets. Financial assets utilizing Level 1 inputs include the NDT investments in active exchange-traded equity securities, mutual funds and U.S. Treasury securities that are in a highly liquid and active market. The Institutional Funds - International Equity investments are valued using the Net Asset Value ("NAV") provided by the administrator of the fund. The NAV price is quoted on a restrictive market although the underlying investments are traded on active markets. The NAV used for determining the fair value of the Institutional Funds-International Equity investments have readily determinable fair values. Accordingly, such fund values are categorized as Level 1.

• Level 2 – Inputs other than quoted market prices included in Level 1 that are observable for the asset or liability either directly or indirectly. Financial assets utilizing Level 2 inputs included the NDT investments in fixed income securities that were sold by the Company on September 30, 2019, and reinvested in similar fixed income securities held in three exchange traded funds. The fair value of these financial instruments is based on evaluated prices that reflect observable market information, such as actual trade information of similar securities, adjusted for observable differences.

• Level 3 – Unobservable inputs using data that is not corroborated by market data and primarily based on internal Company analysis using models and various other analysis. Financial assets utilizing Level 3 inputs are the Company's investment in debt securities.

The securities in the NDT are valued using prices and other relevant information generated by market transactions involving identical or comparable securities. The FASB guidance identifies this valuation technique as the "market approach" with observable

inputs. Prior to the sale of all the Company's fixed income securities classified as available for sale in September 2019, the Company analyzed available for sale securities to determine if losses were other than temporary.

The fair value of the NDT and investments in debt securities at September 30, 2019 and December 31, 2018, and the level within the three levels of the fair value hierarchy defined by the FASB guidance are presented in the table below (in thousands): 

Description of Securities	Fair Value as of September 30, 2019		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)

Texas Regulatory Matters

2017 Texas Retail Rate Case Filing. On February 13, 2017, the Company filed with the City of El Paso, other municipalities incorporated in the Company's Texas service territory and the PUCT in the 2017 Texas Retail Rate Case, a request for an increase in non-fuel base revenues. On November 2, 2017, the Company filed the Joint Motion to Implement Uncontested Stipulation and Agreement with the Administrative Law Judges ("ALJ") for the 2017 Texas Retail Rate Case.

On December 18, 2017, the PUCT issued the PUCT Final Order in Docket No. 46831 ("2017 PUCT Final Order"), which provides, among other things, for the following: (i) an annual non-fuel base rate increase of $14.5 million; (ii) a return on equity of 9.65%; (iii) all new plant in service as filed in the Company's rate filing package was prudent and used and useful and therefore is included in rate base; (iv) recovery of the costs of decommissioning Four Corners Generating Station in the amount of $5.5 million over a seven year period beginning August 1, 2017; (v) the Company to recover reasonable rate case expenses of approximately $3.4 million through a separate surcharge over a three year period; and (vi) a requirement that the Company file a refund tariff if the federal statutory income tax rate, as it relates to the Company, is decreased before the Company files its next rate case. The 2017 PUCT Final Order also established baseline revenue requirements for recovery of future transmission and distribution investment costs (for which the Company could seek recovery after January 1, 2019) and includes a minimum monthly bill of $30.00 for new residential customers with distributed generation, such as private rooftop solar. Additionally, the 2017 PUCT Final Order allowed for the annual recovery of $2.1 million of nuclear decommissioning funding and establishes annual depreciation expense that is approximately $1.9 million lower than the annual amount requested by the Company in its initial filing. Finally, the 2017 PUCT Final Order allowed for the Company to recover revenues associated with the relate back of rates to consumption on and after July 18, 2017, through a separate surcharge.

New base rates, including additional surcharges associated with rate case expenses and the relate back of rates to consumption on and after July 18, 2017, through December 31, 2017, were implemented in January 2018. The surcharge for the relate back of

rates expired on January 9, 2019, with a net over-recovery balance of $0.5 million that was addressed in the fuel reconciliation proceeding filed on September 27, 2019, which was assigned PUCT Docket No. 50058.

For financial reporting purposes, the Company deferred any recognition of the Company's request in its 2017 Texas Retail Rate Case until it received the 2017 PUCT Final Order on December 18, 2017. Accordingly, it reported in the fourth quarter of 2017 the cumulative effect of the 2017 PUCT Final Order, which related back to July 18, 2017.

The 2017 PUCT Final Order required the Company to file a refund tariff if the federal statutory income tax rate, as it relates to the Company, was decreased before the Company files its next general rate case. Following the enactment of the TCJA on December 22, 2017, and in compliance with the 2017 PUCT Final Order, on March 1, 2018, the Company filed with the PUCT and each of its Texas municipalities a proposed refund tariff designed to reduce base charges for Texas customers equivalent to the expected annual decrease of $22.7 million in federal income tax expense resulting from the TCJA changes and an additional refund of $4.3 million for the amortization of a regulatory liability related to the reduced tax expense for the months of January through March of 2018. This filing was assigned PUCT Docket No. 48124. On March 27, 2018, the PUCT approved the Company's proposed refund tariff on an interim basis, subject to refund or surcharge, for customer billing effective April 1, 2018. Each of the Company's municipalities also implemented the Company's proposed tax credits on an interim basis effective April 1, 2018. The refund is reflected in rates over a period of one year beginning April 1, 2018, and will be updated annually until new base rates are implemented pursuant to the Company's next Texas rate case filing. The PUCT issued an order on December 10, 2018, approving the proposed refund tariff. On February 22, 2019, the Company filed with the PUCT and each of its Texas municipalities an application to modify the tax refund tariff to remove the portion of the base rate credit associated with the $4.3 million of regulatory liability amortization, which expired March 31, 2019. The filing was assigned PUCT Docket No. 49251 and approved by final order on June 27, 2019.

Texas Energy Efficiency Cost Recovery Factor ("EECRF"). On May 1, 2017, the Company filed its annual application with the PUCT, which was assigned PUCT Docket No. 47125, to establish its EECRF for 2018. In addition to projected energy efficiency costs for 2018 and a reconciliation of collections to prior year actual costs, the Company requested approval of an incentive bonus for the 2016 energy efficiency program results in accordance with PUCT rules. Interim rates were approved effective January 1, 2018. The Company, the PUCT Staff and the City of El Paso reached an agreement that includes an incentive bonus of $0.8 million. The agreement was filed on January 25, 2018, and was approved by the PUCT on February 15, 2018.

On May 1, 2018, the Company filed its annual application with the PUCT, which was assigned PUCT Docket No. 48332, to establish its EECRF for 2019. In addition to projected energy efficiency costs for 2019 and a reconciliation of collections to actual costs for the prior year, the Company requested approval of a $1.0 million incentive bonus for the 2017 energy efficiency program results in accordance with PUCT rules. Instead of convening a live hearing on the merits of this case, the parties agreed to enter into the record the pre-filed testimony of the parties and certain other exhibits and then file briefs on the contested issues. The ALJ issued a proposal for decision on November 15, 2018, including the Company's fully requested incentive bonus. On January 17, 2019, the PUCT issued a final order approving a modified bonus amount of $0.9 million.

On May 1, 2019, the Company filed its annual application with the PUCT, which was assigned PUCT Docket No. 49496, to establish its EECRF for 2020. In addition to projected energy efficiency costs for 2020 and a reconciliation of collections to actual costs for the prior year, the Company requested approval of a $0.8 million incentive bonus for the 2018 energy efficiency program results in accordance with PUCT rules. On July 1, 2019, the Company requested, and received approval for, a suspension of the procedural schedule in order to pursue settlement of the case. On July 12, 2019, the Company informed the ALJ in the case that all parties had agreed in principle on terms for settlement. On August 14, 2019, the Company filed an unopposed settlement agreement and proposed order which resolved all issues in the proceeding. The case was remanded on August 16, 2019, to the PUCT for a final order approving the settlement agreement and the Company's EECRF rates. On October 11, 2019, the PUCT indicated that certain rate case expenses in the amount of approximately $15 thousand should be removed from the revenue requirement and postponed final consideration until its November 14, 2019, Open Meeting to allow for the filing of additional information reflecting the removal of that expense.

Fuel and Purchased Power Costs. The Company's actual fuel costs, including purchased power energy costs, net of the cost of off-system sales and related shared margins, are recovered from customers through a fixed fuel factor. The PUCT has adopted a fuel cost recovery rule ("Texas Fuel Rule") that allows the Company to seek periodic adjustments to its fixed fuel factor. The Company can seek to revise its fixed fuel factor based upon the approved formula at least four months after its last revision except in the month of December. The Texas Fuel Rule requires the Company to request to refund fuel costs in any month when the over-recovery balance exceeds a threshold material amount and it expects fuel costs to continue to be materially over-recovered. The Texas Fuel Rule also permits the Company to seek to surcharge fuel under-recoveries in any month the balance exceeds a threshold

material amount and it expects fuel cost recovery to continue to be materially under-recovered. Fuel over- and under-recoveries are considered material when they exceed 4% of the previous twelve months' fuel costs. All such fuel revenue and expense activities are subject to periodic final review by the PUCT in periodic fuel reconciliation proceedings.

On October 13, 2017, the Company filed a request with the PUCT, which was assigned PUCT Docket No. 47692, to decrease the Texas fixed fuel factor by approximately 19% to reflect decreased fuel expenses primarily related to a decrease in the price of natural gas used to generate power. The decrease in the Texas fixed fuel factor became effective beginning with the November 2017 billing month.

On April 13, 2018, the Company filed a request with the PUCT, which was assigned PUCT Docket No. 48264, to decrease the Texas fixed fuel factor by approximately 29% to reflect decreased fuel expenses primarily related to a decrease in the price of natural gas used to generate power. On April 25, 2018, the Company's proposed fuel factors were approved on an interim basis effective for the first billing cycle of the May 2018 billing month. The revised factor was approved by the PUCT and the docket closed on May 22, 2018.

On October 15, 2018, the Company filed a request with the PUCT, which was assigned PUCT Docket No. 48781, to decrease the Texas fixed fuel factor by approximately 6.99% to reflect decreased fuel expenses primarily related to a decrease in the price of natural gas used to generate power. On October 25, 2018, the Company's fixed fuel factor was approved on an interim basis effective for the first billing cycle of the November 2018 billing month. The revised factor was approved by the PUCT and the docket closed on November 19, 2018.

On April 29, 2019, the Company filed a petition with the PUCT, which was assigned PUCT Docket No. 49482, requesting authority to implement, beginning on June 1, 2019, a four-month, interim fuel refund of $19.4 million in fuel cost over-recoveries, including interest, for the period from April 2016 through March 2019. On May 30, 2019, the Company's fuel refund credit was approved on an interim basis. The Company implemented the fuel refund in customer bills on June 1, 2019. On September 27, 2019, the PUCT issued a final order approving the fuel refund credits. The fuel refund was completed on September 30, 2019, with a total fuel refund of $20.1 million, including interest, returned to Texas customers.

On September 13, 2019, the Company filed a request with the PUCT, which was assigned PUCT Docket No. 49960, to decrease the Texas fixed fuel factor by approximately 12.2% to reflect decreased fuel expenses primarily related to a decrease in the price of natural gas used to generate power. On September 25, 2019, the Company's fixed fuel factor was approved by the PUCT on an interim basis effective for the first billing cycle of the October 2019 billing month. The Texas fixed fuel factor was determined to be final on October 15, 2019, and will continue until changed by the PUCT. As of September 30, 2019, the Company had a net fuel over-recovery balance of approximately $14.1 million in Texas.

Fuel Reconciliation Proceeding. On September 27, 2019, the Company filed an application with the PUCT, which was assigned PUCT Docket No. 50058, to reconcile $363.0 million of Texas fuel and purchased power expenses incurred during the period of April 1, 2016, through March 31, 2019. The Company cannot predict the outcome of this filing at this time. The April 1, 2019, through September 30, 2019, Texas jurisdictional fuel and purchased power costs subject to a future prudence review total approximately $36.7 million.

Community Solar. On June 8, 2015, the Company filed a petition with the PUCT to initiate a community solar program that includes the construction and ownership of a three-megawatt ("MW") solar photovoltaic system located at Montana Power Station ("MPS"). Participation is on a voluntary basis, and customers contract for a set capacity (kW) amount and receive all energy produced. This case was assigned PUCT Docket No. 44800. The Company filed a settlement agreement among all parties on July 1, 2016, approving the program, and the PUCT approved the settlement agreement and program on September 1, 2016. On April 19, 2017, the Company announced that the entire three-MW program was fully subscribed by approximately 1,500 Texas customers. The Community Solar facility began commercial operation on May 31, 2017.

On March 20, 2018, the Company filed a petition with the PUCT and each of its Texas municipalities to expand its community solar program in Texas to include two-MW of solar powered generation from the ten-MW solar photovoltaic facility located at Newman Power Station ("Newman") and to reduce rates under the community solar tariff. The case before the PUCT was assigned PUCT Docket No. 48181, and a hearing was held on December 4, 2018. The ALJ issued a proposal for decision on March 19, 2019, that approved the project as proposed by the Company. On May 9, 2019, the PUCT approved the Company's request to expand the program utilizing the two-MW of solar powered generation available from Newman. New subscriptions for the expanded program were accepted beginning in June 2019, and new rates for all existing and new customers were implemented in customer bills beginning July 1, 2019. As of June 30, 2019, the expanded program was fully subscribed.

Transmission Cost Recovery Factor. On January 25, 2019, the Company filed an application with the PUCT to establish its Transmission Cost Recovery Factor ("TCRF"), which was assigned PUCT Docket No. 49148 (the "2019 TCRF rate filing"). The 2019 TCRF rate filing is designed to recover a requested $8.2 million of Texas jurisdictional transmission revenue requirement that is not currently being recovered in the Company's Texas base rates for transmission-related investments placed in service from October 1, 2016, through September 30, 2018, net of retirements. Pursuant to the procedural order issued on February 20, 2019, the Company’s TCRF rate was approved on an interim basis effective July 30, 2019, subject to any refund or surcharge to the extent the PUCT’s final order establishes a TCRF rate that differs from the interim rate. On September 12, 2019, the Company filed an unopposed settlement agreement and proposed order for a TCRF revenue requirement of $7.5 million with a provision for recovery of revenue relating-back to the interim effective date of July 30, 2019. Such relate back revenue through September 30, 2019, is expected to approximate $1.4 million. The ALJ remanded the proceeding to the PUCT for consideration of a final order. The Company cannot predict the outcome of this pending matter at this time.

Distribution Cost Recovery Factor. On March 28, 2019, the Company filed an application with the PUCT and each of its Texas municipalities to establish its Distribution Cost Recovery Factor (“DCRF”), which was assigned PUCT Docket No. 49395 (the “2019 DCRF rate filing”). The 2019 DCRF rate filing is designed to recover a requested $7.9 million of Texas jurisdictional distribution revenue requirement that is not currently being recovered in the Company’s Texas base rates for distribution-related investments placed in service from October 1, 2016, through December 31, 2018, net of retirements. On August 13, 2019, the Company filed an unopposed settlement agreement and proposed order which resolved all issues in the proceeding and approved a DCRF revenue requirement of $7.8 million. On September 27, 2019, the PUCT issued a final order reflecting the settlement agreement, and the Company's DCRF rates became effective in customer bills beginning October 1, 2019.

Other Required Approvals. The Company has obtained other required approvals for tariffs and other approvals required by the PURA and the PUCT.

New Mexico Regulatory Matters

Future New Mexico Rate Case Filing. The Company was required to file its next New Mexico base rate case no later than July 31, 2019. On July 10, 2019, the NMRPC issued an order approving a joint request by the Company, NMPRC Staff, and the New Mexico Attorney General to delay filing of the Company's next base rate case until after the conclusion of a proceeding addressing the Merger. The NMPRC order requires the Company to file its next rate case application within three months of the conclusion of the proceeding addressing the Merger in New Mexico. The Company cannot predict the outcome of this filing at this time. See Part I, Item 1, Financial Statements, Note N of Notes to Financial Statements for further discussion.

New Mexico Order Commencing Review of the Effects of the TCJA on Regulated New Mexico Utilities. On January 24, 2018, the NMPRC initiated a proceeding in Case No. 18-00016-UT on the impact of the TCJA on New Mexico regulated utilities. On April 4, 2018, the NMPRC issued an order requiring the Company to file a proposed interim rate rider to adjust the Company's New Mexico base revenues in amounts equivalent to the Company's reduced income tax expense for New Mexico customers resulting from the TCJA, to be implemented on or before May 1, 2018. The NMPRC order further requires that the Company record and track a regulatory liability for the excess accumulated deferred income taxes created by the change in the federal corporate income tax rate, consistent with the effective date of the TCJA, and subject to amortization determined by the NMPRC in the Company's next general rate case. The Company recorded such a regulatory liability during the quarter ended December 31, 2017. On April 16, 2018, after consultation with the New Mexico Attorney General pursuant to the NMPRC order, the Company filed an interim rate rider with the NMPRC with a proposed effective date of May 1, 2018. The annualized credits expected to be refunded to New Mexico customers approximate $4.9 million. The Company implemented the interim rate rider in customer bills beginning May 1, 2018 pursuant to the NMPRC order.

On September 5, 2018, the NMPRC issued an order in Case No. 17-00255-UT involving Southwestern Public Service Company’s ("SPS’s") request to change rates in which the NMPRC directed SPS to refund the difference in corporate tax rate from January 1, 2018, through the effective date of new rates. SPS appealed the NMPRC order to the New Mexico Supreme Court in Southwestern Public Service Co. v. NMPRC, No. S-1-SC-37248 ("SPS Appeal No. 1"), challenging the refund as prohibited retroactive ratemaking among other reasons. The New Mexico Supreme Court issued a partial and interim stay of the rates on September 26, 2018. On September 12, 2018, the NMPRC in Case No. 18-00016-UT issued an Order Regarding the Disposition of Tax Savings Under the Federal Tax Cuts and Jobs Act of 2017, which put public utilities on notice that all revenue collected through general rates for the purpose of payment of federal income taxes is and will continue to be subject to possible refund upon a subsequent determination to be made in the appropriate pending or future NMPRC adjudicatory hearing. On October 11, 2018, SPS filed a Notice of Appeal of that NMPRC order to the New Mexico Supreme Court in Southwestern Public Service Co. v. NMPRC, No. S-1-SC-37308 ("SPS Appeal No. 2"). On February 15, 2019, the NMPRC and SPS filed a joint motion for remand

and stipulated dismissal of SPS appeals of NMPRC orders with the New Mexico Supreme Court, which among other things, reflected agreements between the NMPRC and SPS, which in part provide that the NMPRC will replace the order in Case No. 17-00255-UT with a new order that eliminates the retroactive TCJA refund and that SPS will request dismissal of SPS Appeals No. 1 and No. 2. On February 28, 2019, the New Mexico Supreme Court remanded SPS Appeal No. 1 back to the NMPRC and dismissed the appeal. On March 6, 2019, the NMPRC issued a revised final order on remand in Case No. 17-00255-UT that, in part, eliminated the retroactive TCJA refund.

Fuel and Purchased Power Costs. Pursuant to NMPRC Rule 550, fuel and purchased power costs, net of the cost of off-system sales and related shared margins, are reconciled to actual costs on a monthly basis and recovered or refunded to customers the second succeeding month through the Fuel and Purchased Power Cost Adjustment Clause ("FPPCAC"). The Company must file an application for continued use of its FPPCAC no more than four years from the date its last FPPCAC was continued. As required, the Company filed a request to continue use of its FPPCAC with the NMPRC on January 5, 2018, which was assigned Case No. 18-00006-UT. The NMPRC issued a final order in the case on February 13, 2019, which authorized the Company to continue use of its FPPCAC without change and approved the Company's reconciliation of its fuel and purchased power costs for the period January 1, 2015, through December 31, 2016. New Mexico jurisdictional costs subject to prudence review are costs from January 1, 2017, through September 30, 2019, that total approximately $107.3 million. At September 30, 2019, the Company had a net fuel under-recovery balance of approximately $1.4 million related to the FPPCAC in New Mexico.

New Mexico Renewable Portfolio Standard. Effective January 1, 2018, pursuant to the final order in NMPRC Case No. 17-00090-UT, the Renewable Portfolio Standard ("RPS") costs for New Mexico are recovered through a separate RPS Cost Rider and not through the FPPCAC. At September 30, 2019, the Company had a net fuel over-recovery balance related to the RPS Cost Rider of approximately $1.6 million. The RPS Cost Rider is updated in an annual NMPRC filing, including a reconciliation of the prior year’s RPS costs and RPS Cost Rider revenue. On October 1, 2019, the Company filed its required application with the NMPRC for its 2019 Annual Renewable Plan in Case No. 19-0099-UT and for adjustment of its RPS Cost Rider for reconciliation of 2018 costs and revenues and to recover RPS costs for 2020. The application requests approvals of the Company's plan to meet requirements of the Renewable Energy Act, as amended in 2019. The Company cannot predict the outcome of this filing at this time.

5-MW Holloman Air Force Base ("HAFB") Facility Certificate of Convenience and Necessity ("CCN"). On October 7, 2015, in Case No. 15-00185-UT, the NMPRC issued a final order approving a CCN for a five-MW solar power generation facility located on HAFB in the Company's service territory in New Mexico. The Company and HAFB negotiated a retail contract, which includes a power sales agreement for the facility, to replace the existing load retention agreement that was approved by NMPRC final order issued October 5, 2016, in Case No. 16-00224-UT. The solar generation facility began commercial operation on October 18, 2018.

New Mexico Efficient Use of Energy Recovery Factor. On July 1, 2016, the Company filed its annual application with the NMPRC requesting approval of its 2017 Energy Efficiency and Load Management Plan and to establish the Efficient Use of Energy Recovery Factor ("EUERF") for 2017. In addition to projected energy efficiency costs for 2017, the Company requested approval of a $0.4 million incentive for 2017 energy efficiency programs in accordance with NMPRC rules. This application was assigned Case No. 16-00185-UT. On February 22, 2017, the NMPRC issued a final order approving the Company’s 2017 Energy Efficiency and Load Management Plan. The Company’s EUERF was approved and effective in customer bills beginning on March 1, 2017. NMPRC rules authorize continuation of the energy efficiency programs and incentive approved in Case No. 16-00185-UT through 2018. The Company recorded approved incentives in operating revenues of $0.3 million and $0.7 million in 2018 and 2017, respectively, related to its 2015 through 2017 Energy Efficiency and Load Management Plans. During the three months ended September 30, 2019, the Company recorded an incentive in operating revenues of $0.4 million related to its 2018 Energy Efficiency Programs.

On July 2, 2018, the Company filed its required application with the NMPRC for approval of its 2019-2021 Energy Efficiency and Load Management Plan and EUERF. The application was assigned Case No. 18-00116-UT. On March 6, 2019, the NMPRC issued a final order approving: (i) the Company's 2019-2021 Energy Efficiency and Load Management Plan, with minor program modifications; (ii) the base incentive of 7.1% of program expenditures, or approximately $0.4 million annually for 2019-2021; and (iii) the continuation of the Company's EUERF.

Community Solar. On April 24, 2018, the Company filed an application with the NMPRC to initiate a community solar program in New Mexico to include construction and ownership of a two-MW solar photovoltaic system located in Doña Ana County near the City of Las Cruces. Customer participation would have been on a voluntary basis, and customers would have contracted for a set capacity (kW) amount and would have received all energy produced by their subscribed capacity. The application was assigned Case No. 18-00099-UT and was dismissed without prejudice on October 31, 2018. The NMPRC set aside its

October 31, 2018, order dismissing the application without prejudice, and on December 19, 2018, the NMPRC issued an Order Requiring El Paso Electric Company to Conduct Request for Proposals and to Amend Application; Order Extending Statutory Period and Appointing Hearing Examiner that would have required the Company to amend its initially-filed application on or before February 15, 2019. However, on January 10, 2019, the NMPRC with three new Commissioners reconsidered its December 19, 2018 order and dismissed the Community Solar application without prejudice. The case is now closed.

Integrated Resource Plan ("IRP"). On September 17, 2018, the Company filed its IRP with the NMPRC for the period 2018-2037 ("2018 IRP") in Case No. 18-00293-UT as required by regulation and the Joint Stipulation in NMPRC Case No. 15-00241-UT, which was the Company's prior integrated resource plan filing. The triennial filing requires a public advisory process as part of the development of the plan to identify a cost-effective portfolio of resources. The filed plan is subject to written public comments filed with the NMPRC to which the Company responded on October 29, 2018. NMPRC Staff filed a written report on November 16, 2018, recommending that the NMPRC return the 2018 IRP to the Company with instructions for re-filing to correct 12 deficiencies identified by the NMPRC Staff report. On December 5, 2018, the NMPRC issued an Order Partially Accepting Integrated Resource Plan; Order Requiring Refiling for Deficiencies. Pursuant to that order, on January 3, 2019, the Company filed an amended 2018 IRP. On January 10, 2019, in light of a pending motion for reconsideration, the NMPRC ordered its Staff to provide additional information and respond to issues raised regarding the filed 2018 IRP. On March 15, 2019, NMPRC Staff filed the additional response and recommended that the Company correct one deficiency identified. On September 18, 2019, the NMPRC issued a variance from the IRP rule on commission review, acceptance and action, and closed the docket.

Issuance of Long-Term Debt, Securities Financing, and Guarantee of Debt. On October 7, 2015, the Company received approval in NMPRC Case No. 15-00280-UT to guarantee the issuance of up to $65.0 million of long-term debt by the Rio Grande Resources Trust II ("RGRT") to finance future purchases of nuclear fuel and to refinance existing nuclear fuel debt obligations, which remains effective. Under this authorization, on June 28, 2018, the RGRT issued $65.0 million in aggregate principal amount of 4.07% Senior Guaranteed Notes due August 15, 2025. On October 4, 2017, the Company received additional approval in NMPRC Case No. 17-00217-UT to amend and extend the Company's Revolving Credit Facility ("RCF"), issue up to $350.0 million in long-term debt and to redeem and refinance the $63.5 million 2009 Series A 7.25% Pollution Control Bonds ("PCBs") and the $37.1 million 2009 Series B 7.25% PCBs. The NMPRC approval to issue $350.0 million in long-term debt supersedes its prior approval. Under this authorization, on June 28, 2018, the Company issued $125.0 million in aggregate principal amount of the Company's 4.22% Senior Notes due August 15, 2028. Additionally, on September 13, 2018, the Company and the Bank of New York Mellon Trust Company, N.A., as trustee of the RGRT, entered into a $350.0 million third amended and restated credit agreement.

On January 30, 2019, the Company submitted an application with the NMPRC seeking approval to issue shares of common stock, including the reissuance of treasury shares, in an amount up to $200.0 million in one or more transactions. The application was assigned Case No. 19-00033-UT, and the NMPRC issued a final order approving the Company's request on March 27, 2019. On February 1, 2019 and April 1, 2019, the Company purchased in lieu of redemption all $63.5 million aggregate principal amount of 2009 Series A 7.25% PCBs and $37.1 million aggregate principal amount of 2009 Series B 7.25% PCBs, respectively. The bonds were purchased utilizing funds borrowed under the RCF. On May 22, 2019, the Company reoffered and sold $63.5 million aggregate principal amount of 2009 Series A 7.25% PCBs and $37.1 million aggregate principal amount of 2009 Series B 7.25% PCBs with a fixed interest rate of 3.60% per annum until the bonds mature on February 1, 2040 and April 1, 2040, respectively. The bonds are subject to optional redemption at a redemption price of par on or after June 1, 2029. See Part I, Item 1, Financial Statements, Note M of Notes to Financial Statements for further discussion.

Amendments to the New Mexico Renewable Energy Act (“REA”). The REA requires electric utilities to meet an RPS of twenty percent of its total retail sales to New Mexico customers by 2020, reduced for sales to  qualifying large non-governmental customers whose costs are capped under the REA (“Large Customer Adjustment”) and subject to a reasonable cost threshold (“RCT”) established by the NMPRC and currently set by the NMPRC at 3 percent of customers’ bills.  Effective June 14, 2019, the New Mexico Energy Transition Act amends the REA (the “Amended REA”) to, among other amendments: (i) increase the RPS to forty percent by 2025, fifty percent by 2030, and eighty percent by 2040; (ii) impose a zero-carbon standard by 2045; (iii) eliminate the Large Customer Adjustment; (iv) set a statutory RCT; and (v) provide cost recovery for certain undepreciated investments and decommissioning costs (i.e., coal-fired generation) associated with generation required by the NMPRC to be discontinued and replaced with lower or zero-carbon generation. In administering the eighty percent RPS and zero-carbon standards, the Amended REA requires by Commission to consider certain factors, including safety, reliability and rate impact to customers.  On October 10, 2019, the NMPRC initiated a rulemaking proceeding to implement the Amended REA in Case No. 19-00296-UT.  The Company is currently evaluating the impact that the Amended REA may have on its operations. Further, the Company has not determined the costs associated with complying with the Amended REA including potential fines that could be associated with non-compliance.

Other Required Approvals. The Company has obtained other required approvals for tariffs and other approvals as required by the NMPUA and the NMPRC.

Federal Regulatory Matters

Inquiry Regarding the Effect of the TCJA on Commission-Jurisdictional Rates and Order to Show Cause. On March 15, 2018, the FERC issued two show cause orders under Section 206 of the Federal Power Act and Rule 209(a) of the FERC’s Rules of Practice and Procedure, directing 48 individual public utilities with stated transmission rates or transmission formula rates with a fixed line item of 35% for the federal income tax component to, within 60 days of the date of the orders, either (1) propose revisions to their transmission rates under their open access transmission tariffs or transmission owner tariffs on file with the FERC, or (2) show cause why they should not be required to do so ("Show Cause Proceeding"). The Company was included in the list of public utilities impacted by the FERC orders. On May 14, 2018, the Company submitted its response, as required by the FERC order, which demonstrated that the reduced annual income tax does not cause the Company's total transmission revenues to become excessive and therefore no rate reduction was justified. Instead, the Company stated in its response that it will prepare for a future filing in which it will seek approval for revised Open Access Transmission Tariff ("OATT") rates that would include the recovery of an increased total transmission revenue requirement from OATT customers based on current circumstances and appropriate forward-looking adjustments. On November 15, 2018, FERC issued an order finding that the Company had demonstrated that no rate reduction was justified and terminating the Show Cause Proceeding. The Company expects to file its request for approval to revise OATT rates in the fourth quarter of 2019 or early 2020.

Notice of Proposed Rulemaking on Public Utility Transmission Changes to Address Accumulated Deferred Income Taxes. On November 15, 2018, the FERC issued a Notice of Proposed Rulemaking ("NOPR") that proposes to direct public utilities with transmission OATT rates, a transmission owner tariff or a rate schedule to determine the amount of excess or deficient accumulated deferred income taxes caused by the TCJA’s reduction to the federal corporate income tax rate and return or recover this amount to or from customers. The NOPR has been assigned FERC Docket No. RM19-5-000. The Company is currently evaluating the impact of this proposed rulemaking.

Issuance of Long-Term Debt, Securities Financing, and Guarantee of Debt. On October 31, 2017, the FERC issued an order in Docket No. ES17-54-000 approving the Company’s filing to (i) amend and extend the RCF; (ii) issue up to $350.0 million in long-term debt; (iii) guarantee the issuance of up to $65.0 million of long-term debt by the RGRT; and (iv) redeem, refinance, and/or replace the $63.5 million 2009 Series A 7.25% PCBs and the $37.1 million 2009 Series B 7.25% PCBs. The order also approved the Company's request to continue to utilize the Company's existing RCF with the ability to amend and extend at a future date. The authorization was effective from November 15, 2017, through November 14, 2019, and superseded prior FERC approvals. Under this authorization, on June 28, 2018, the Company issued $125.0 million in aggregate principal amount of the Company's 4.22% Senior Notes due August 15, 2028, and the RGRT issued $65.0 million in aggregate principal amount of its 4.07% Senior Guaranteed Notes due August 15, 2025. Also, on September 13, 2018, the Company and the Bank of New York Mellon Trust Company, N.A., as trustee of the RGRT, entered into a $350.0 million third amended and restated credit agreement. On February 1, 2019 and April 1, 2019, the Company purchased in lieu of redemption all $63.5 million aggregate principal amount of 2009 Series A 7.25% PCBs and $37.1 million aggregate principal amount of 2009 Series B 7.25% PCBs, respectively. The bonds were purchased utilizing funds borrowed under the RCF.

On January 30, 2019, the Company submitted an application with the FERC seeking approval to issue shares of common stock, including the reissuance of treasury shares, in an amount up to $200.0 million in one or more transactions. Included in the FERC application, the Company also requested various debt-related authorizations: approval to utilize the existing RCF for short-term borrowings not to exceed $400.0 million at any one time; to issue up to $225.0 million in new long-term debt; and to remarket the $63.5 million 2009 Series A 7.25% PCBs and the $37.1 million 2009 Series B 7.25% PCBs in the form of replacement bonds or senior notes of equivalent value, not to exceed $100.6 million. On April 18, 2019, the FERC issued an order authorizing the issuances through April 18, 2021. On May 22, 2019, the Company reoffered and sold $63.5 million aggregate principal amount of 2009 Series A 7.25% PCBs and $37.1 million aggregate principal amount of 2009 Series B 7.25% PCBs with a fixed interest rate of 3.60% per annum until the bonds mature on February 1, 2040 and April 1, 2040, respectively. The bonds are subject to optional redemption at a redemption price of par on or after June 1, 2029. See Part I, Item 1, Financial Statements, Note M of Notes to Financial Statements for further discussion.

FERC Compliance Audit, Docket No. PA19-3-000. On February 6, 2019, the FERC notified the Company that it is commencing an audit that is intended to evaluate the Company’s compliance with: (1) the approved terms, conditions, and rates of its OATT;

(2) the accounting requirements of the Uniform System of Accounts; (3) the reporting requirements of the FERC Form No. 1 Annual Report and Supplemental Form 3-Q Quarterly Financial Reports; and (4) the regulations regarding Open Access Same-time Information Systems. The audit covers the period January 1, 2016 to the present. The Company cannot predict the outcome or findings, if any, of the FERC at this time.

Other Required Approvals. The Company has obtained required approvals for rates, tariffs and other approvals as required by the Federal Power Act and the FERC.

Principles Of Preparation (Policy)

9 Months Ended

Sep. 30, 2019

Accounting Policies [Abstract]

Use of Estimates, Policy

Use of Estimates. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The Company evaluates its estimates on an on-going basis, including those related to depreciation, unbilled revenue, income taxes, fuel costs, pension and other post-retirement obligations and asset retirement obligations. Actual results could differ from those estimates.

Revenue Recognition, Policy

Operating Revenues. The Company accrues revenues for services rendered, including unbilled electric service revenues. The Company recognizes revenue associated with contracts with customers when performance obligations under the terms of the contract with the customer are satisfied. Revenue is measured as the amount of consideration the Company receives in exchange for transferring goods or providing services to the customer. Taxes collected concurrently with revenue producing activities are excluded from revenue. Unbilled revenues are recorded for estimated amounts of energy delivered in the period following the customer's last billing cycle to the end of the reporting period. Unbilled revenues are estimated based on monthly generation volumes and by applying an average revenue/kilowatt-hour ("kWh") to the number of estimated kWhs delivered but not billed. Accounts receivable included accrued unbilled revenues of $33.3 million at September 30, 2019 and $21.6 million at December 31, 2018.

The Company’s Texas retail customers are billed under base rates and a fixed fuel factor approved by the Public Utility Commission of Texas ("PUCT"). The Company’s New Mexico retail customers are billed under base rates and a fuel adjustment clause that is adjusted monthly, as approved by the New Mexico Public Regulation Commission ("NMPRC"). The Company's Federal Energy Regulatory Commission ("FERC") sales for resale customers are billed under formula base rates and fuel factors and a fuel adjustment clause that is adjusted monthly. The Company’s recovery of fuel and purchased power expenses is subject to periodic reconciliations of actual fuel and purchased power expenses incurred to actual fuel revenues collected. The difference between fuel and purchased power expenses incurred and fuel revenues charged to customers is reflected as over/under-collection of fuel revenues, which is included in regulatory liabilities/assets - current in the balance sheets. See Part I, Item 1, Financial Statements, Note D of Notes to Financial Statements for further discussion.

Leases, Policy

Leases. The Company determines if an arrangement contains a lease and the classification of that lease at inception. Operating lease right-of-use (“ROU”) assets represent the Company’s right to use an underlying asset for the lease term and operating lease liabilities represent the obligation to make payments under the lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the estimated present value of the minimum lease payments over the lease term. In determining lease terms, the Company considers any options to extend or terminate the lease that are reasonably certain of being exercised. As the Company’s leases do not include an implicit rate, the Company uses an estimated incremental borrowing rate, at lease commencement, to determine the present value of the future lease payments. In calculating the incremental borrowing rate, the Company takes into consideration recent debt issuances and other data for instruments with similar characteristics. The Company’s lease agreements do not contain residual value guarantees or restrictive covenants. For leases with lease and non-lease components, the Company has elected to account for the consideration as a single lease component. The Company has also elected not to record leases with a term of 12 months or less on the balance sheets. The operating lease ROU assets are included as part of electric plant in service and lease liabilities are included as part of current and non-current liabilities in the Company’s balance sheets.

Depreciation, Depletion, and Amortization, Policy

Depreciation. The Company routinely evaluates the depreciable service lives, cost of removal and salvage values of its property, plant and equipment. Depreciation is provided on a straight-line basis over the estimated remaining lives of the assets (ranging in average from 5 to 48 years). When property subject to composite depreciation is retired or otherwise disposed of in the normal course of business, its cost together with the cost of removal, less salvage is charged to accumulated depreciation. For other property dispositions, the applicable cost and accumulated depreciation is removed from the balance sheet accounts and a gain or loss is recognized.

New Accounting Standards, Policy

New Accounting Standards Adopted

In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-02, Leases (Topic 842), to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and requiring qualitative and quantitative disclosures on leasing agreements. ASU 2016-02 maintains a distinction between finance leases and operating leases similar to the distinction under previous lease guidance for capital leases and operating leases. Effective January 1, 2019, the Company adopted ASU 2016-02 using the modified retrospective method, applying the transition provisions to the beginning of the period of adoption rather than to the earliest comparative period presented, which continues to be reported in accordance with previous lease guidance, Accounting Standards Codification Topic 840. The Company adopted the package of practical expedients, which does not require the Company to reassess: (i) whether an arrangement contained a lease, (ii) lease classification for any expired or existing leases, and (iii) initial direct costs for any expired or existing leases. The Company also adopted the practical expedient related to land easements, which allowed carry forward accounting treatment for existing land easements. The most significant impact of adopting ASU 2016-02, as of January 1, 2019, was the recording of approximately $6.3 million of operating lease liabilities and related ROU assets with no cumulative effect adjustment to retained earnings. The Company anticipates the ongoing impact of the new standard to be immaterial to net income and cash flows. See Part I, Item 1, Financial Statements, Note I of Notes to Financial Statements for further discussion.

In February 2018, the FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220), as a result of concerns raised due to the federal law commonly referred to as the Tax Cuts and Jobs Act of 2017 ("TCJA"). More specifically, because the remeasurement of deferred taxes due to the change in the federal corporate income tax rate is required to be included in income from continuing operations, the tax effects of items within accumulated other comprehensive income ("AOCI") (referred to as stranded tax effects) do not reflect the appropriate tax rate. ASU 2018-02 allows companies an election to reclassify stranded taxes from AOCI to retained earnings. The amount of the reclassification would be the difference between the historical federal corporate income tax rate of 35% and the newly enacted 21% federal corporate income tax rate, which approximates $7.2 million. The provisions of ASU 2018-02 are effective for fiscal years and interim periods within that reporting period beginning after December 15, 2018. The Company adopted ASU 2018-02 on January 1, 2019, and has elected to not reclassify stranded taxes from AOCI to retained earnings.

New Accounting Standards to be Adopted in the Future

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326). ASU 2016-13 changes how companies measure and recognize credit impairment for many financial assets. The new expected credit loss model will require companies to immediately recognize an estimate of credit losses expected to occur over the remaining life of the financial assets that are in the scope of the standard. ASU 2016-13 will be required for reporting periods beginning after December 15, 2019. ASU 2016-13 will be applied in a modified retrospective approach through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is implemented. The Company is currently in the process of evaluating the impact of the new standard, which includes continuing to monitor activities of the FASB, including the impact of ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments and ASU 2019-05, Financial Instruments - Credit Losses (Topic 326): Targeted Transition Relief.
