SOUTHWEST GAS CORPORATION						September 30, 2020

Note 1 – ~~Nature~~Background, Organization, and Summary of ~~Operations and Basis of Presentation~~

Significant Accounting Policies

Nature of Operations. Southwest Gas Holdings, Inc. is a holding company, owning all of the shares of common stock of Southwest Gas Corporation (“Southwest” or the “natural gas operations” segment) and ~~prior to August 2017, 96.6%~~all of the shares of common stock of Centuri Construction Group, Inc. During August 2017, Southwest Gas Holdings, Inc. acquired the remaining 3.4% equity interest in Centuri Construction Group, Inc. that was held by the previous owners (and was previously reflected as a redeemable noncontrolling interest). Refer to ~~Note 9 – Construction Services Redeemable Noncontrolling Interestfor additional information.~~

In January 2017, a previously contemplated and approved reorganization under a holding company structure was made effective. The reorganization was designed to provide further separation between regulated and unregulated businesses, and to provide additional financing flexibility. Coincident with the effective date of the reorganization, existing shareholders of Southwest Gas Corporation became shareholders of Southwest Gas Holdings, Inc., on a~~one-for-one~~ ~~basis, with the same number of shares and same ownership percentage as they held immediately prior to the reorganization. At the same time, Southwest Gas Corporation and Centuri Construction~~ Group, Inc. (“~~Centuri”~~Centuri,” or the ~~“construction~~“utility infrastructure services” segment) ~~each became subsidiaries of the publicly traded holding company; whereas, historically, Centuri had been a direct subsidiary of~~ .

Southwest ~~Gas Corporation.~~

~~Southwest Gas Corporation (“Southwest” or the “natural gas operations segment”)~~ is engaged in the business of purchasing, distributing, and transporting natural gas for customers in portions of Arizona, Nevada, and California. Public utility rates, practices, facilities, and service territories of Southwest are subject to regulatory oversight. The timing and amount of rate relief can materially impact results of operations. Natural gas purchases and the timing of related recoveries can materially impact liquidity. Results for the natural gas operations segment are higher during winter periods due to the seasonality incorporated in its regulatory rate structures.

Centuri is a comprehensive ~~construction~~utility infrastructure services enterprise dedicated to ~~meeting the growing demands~~delivering a diverse array of solutions to North ~~American utilities, energy~~America’s gas and ~~industrial markets.~~electric providers. Centuri derives revenue primarily from installation, replacement, repair, and maintenance of energy distribution ~~systems, and developing industrial construction solutions.~~systems. Centuri operations are generally conducted under the business names of NPL Construction Co. (“NPL”), NPL Canada Ltd. (“NPL Canada”~~, formerly Link-Line Contractors Ltd.~~), ~~W.S. Nicholls Construction,~~New England Utility Constructors, Inc. (“~~W.S. Nicholls”~~Neuco”), and ~~Brigadier Pipelines Inc.~~Linetec Services, LLC (“~~Brigadier”~~Linetec”). ~~Typically, Centuri revenues~~Utility infrastructure services activity is seasonal in most of Centuri’s operating areas. Peak periods are ~~lowest during the first quarter of the year due to unfavorable winter weather conditions. Operating revenues typically improve as more favorable weather conditions occur during~~ the summer and fall ~~months.~~

months in colder climate areas, such as the northeastern and midwestern United States (“U.S.”) and in Canada. In warmer climate areas, such as the southwestern and southeastern U.S., utility infrastructure services activity continues year round.

Basis of Presentation. The condensed consolidated financial statements ~~for~~of Southwest Gas Holdings, Inc. and subsidiaries (the “Company”) and Southwest included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). The year-end condensed balance sheet data was derived from audited financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with ~~United States~~U.S. generally accepted accounting principles (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations. As indicated above, in connection with the holding company reorganization, Centuri ceased to be a subsidiary of Southwest and became a subsidiary of Southwest Gas Holdings, Inc. To give effect to this change, the separate condensed consolidated financial statements related to Southwest Gas Corporation, which are included in this~~Form 10-Q,~~ depict Centuri-related amounts for periods prior to January 1, 2017 as discontinued operations. Because the transfer of Centuri from Southwest Gas Corporation to Southwest Gas Holdings, Inc. was effectuated as an equity transaction and not a sale, assets and liabilities subject to the discontinued operations presentation have been reflected as noncurrent on the Southwest Gas Corporation Condensed Consolidated Balance Sheet. Those assets and liabilities are detailed in~~Note~~ ~~10 – Reorganization Impacts – Discontinued Operations Solely Related to Southwest Gas Corporation~~~~,and include both current andnon-current~~ ~~amounts.~~

No substantive change has occurred with regard to the Company’s business segments on the whole, or in the primary businesses comprising those segments as a result of the foregoing organizational changes. Centuri operations continue to be part of continuing operations and included in the consolidated financial statements of Southwest Gas Holdings, Inc.

whole.

The preparation of the condensed consolidated financial statements 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.


~~SOUTHWEST GAS HOLDINGS, INC.~~		~~Form 10-Q~~
~~SOUTHWEST GAS CORPORATION~~		~~September 30, 2017~~

Actual results could differ from those estimates. In the opinion of management, all adjustments, consisting of normal recurring items and estimates necessary for a fair ~~statement~~depiction of results for the interim periods, have been made. ~~It is suggested that these~~Globally, the novel Coronavirus (“COVID-19”) pandemic has created volatility, uncertainty, and economic disruption. Utility operations have been deemed “essential services” and utility infrastructure services have, to a large extent, been similarly characterized by government officials. Management has considered the impact of the pandemic and adjusted certain estimates, where relevant, used in the preparation of the condensed consolidated financial statements.

These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the ~~2016~~2019 Annual Report to ~~Shareholders,~~Stockholders, which is incorporated by reference into the ~~2016~~2019 Form 10-K.

~~Other current liabilities~~~~. Other current liabilities of Southwest Gas Corporation include $21 million of dividends declared but not yet~~or paid to ~~Southwest Gas Holdings, Inc.~~transfer a liability in an orderly transaction between market participants at ~~September 30, 2017.~~

~~Cash~~the measurement date.

U.S. GAAP states that a fair value measurement should be based on the assumptions that market participants would use in pricing the asset or liability and ~~Cash Equivalents.~~ ~~For purposes of reporting consolidated cash flows, cash and cash equivalents include cash on hand and financial instruments with~~establishes a ~~purchase-date maturity of three months or less. In general, cash and cash equivalents fall within Level 1 (quoted prices for identical financial instruments) of the three-level~~ fair value hierarchy that ranks the inputs used to measure fair value by their reliability. ~~However, cash~~The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and ~~cash equivalents at September 30, 2017~~the lowest priority to fair values derived from unobservable inputs (Level 3 measurements).

The three levels of the fair value hierarchy ~~due~~are as follows:

Level 1 – quoted prices (unadjusted) in active markets for identical assets or liabilities that a company has the ability to access at the measurement date.

Level 2 – inputs other than quoted prices included within Level 1 that are observable for similar assets or liabilities, either directly or indirectly.

Level 3 – unobservable inputs for the asset or liability. Unobservable inputs are used to measure fair value to the ~~asset valuation methods used by money~~extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market ~~funds.~~

~~Significantnon-cash~~ investing and financing activities included the following: Upon contract expiration, customer advances of approximately $1.9 million and $3.6 million, during the first nine months of 2017 and 2016, respectively, were applied as contributions toward utility construction activity ~~and representnon-cash~~ ~~investing activity.~~

~~Adoption of Accounting Standards Update (“ASU”) No.~~ ~~2016-09.~~ ~~As of January 1, 2017, the Company adopted Financial Accounting Standards Board (“FASB”) ASUNo. 2016-09~~ “Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” The adoption of this update is considered a change in accounting principle. Among other things, the update clarifies that all cash payments made to taxing authorities on the employees’ behalf for withheld shares should be presented as financing activities on the statement of cash flows. This change is required to be presented in the cash flow statement retrospectively. A new category, Withholding remittance – share-based compensation has been added to the Cash Flow from Financing Activities section of the Condensed Consolidated Statements of Cash Flows for both Southwest Gas Holdings, Inc. and Southwest Gas Corporation. The withheld taxes were included in the Other current assets and liabilities line item of the Condensed Consolidated Statements of Cash Flows in previous periods. Therefore, upon adoption, amounts presented as cash inflows from Other current assets and liabilities under the Cash Flow from Operating Activities section of the Southwest Gas Holdings, Inc. Condensed Consolidated Statements of Cash Flows were revised from $9.9 million to $12 million for the ~~nine months ended September 30, 2016 and inflows in~~asset or liability at the same category for the twelve months ended September 30, 2016 were revised from $19.9 million to $22 million. In addition, while standalone financial statements were not previously presented for natural gas operations, for reasons related to the holding company reorganization discussed above, they are now presented. Therefore, upon adoption of this standard, the Cash Flow from Operating Activities section of the Southwest Gas Corporation Condensed Consolidated Statements of Cash Flows reflects a reclassification of cash outflows from Other current assets and liabilities from $2.9 million to $819,000 for the nine months ended September 30, 2016 and cash inflows in the same category were revised from $7 million to $9.1 million for the twelve months ended September 30, 2016.

Under the new guidance, the Company can withhold any amount between the minimum and maximum individual statutory tax rates and still treat the entire award as equity. The Company intends to administer withholding such that awards under stock compensation programs will continue to be treated as equity awards.

~~In addition to the above, the update requires all incometax-related~~ cash flows resulting from share-based payments (unrelated to employee withholding) be reported as operating activities on the statement of cash flows, a change from the previous requirement to present windfall tax benefits as an inflow from financing activities and an outflow from operating activities. The Company chose to apply this presentation requirement of the update prospectively as permitted. Therefore, prior periods were not impacted in implementing this provision of the update.

Included in the table above isare the ~~change in~~net cash surrender values of company-owned life insurance (“COLI”) ~~policies (including net death benefits recognized).~~policies. These life insurance policies on members of management and other key employees are used by Southwest to indemnify itself against the loss of talent, expertise, and knowledge, as well as to provide indirect funding for certain nonqualified benefit plans. Balances reflect impacts of equity and fixed-income securities underlying the cash surrender values at each reporting date; however, ultimately, only the insurance proceeds are ever actually received, due to management’s intent to hold the policies to maturity.

Cash and Cash Equivalents. For purposes of reporting consolidated cash flows, cash and cash equivalents include cash on hand and financial instruments with original maturities of three months or less. Such investments are carried at cost, which approximates market value. Cash and cash equivalents of Southwest and the Company include money market fund investments totaling approximately $40,000 for both entities at September 30, 2020, and $23.5 million and $26.7 million, for each, respectively, at December 31, 2019, which fall within Level 2 of the fair value hierarchy, due to the asset valuation methods used by money market funds.

Typical non-cash investing activities for Southwest include customer advances applied as contributions toward utility construction activity, capital expenditures that were not paid as of period-end reporting dates but rather included in accounts payable, and right-of-use assets obtained in exchange for lease liabilities, which are non-cash investing and financing activities. Amounts related to such activities were immaterial for the periods presented herein.

Intercompany Transactions. Centuri recognizes revenues generated from contracts with Southwest (see Note 7 – Segment Information). The accounts receivable balance, revenues, and associated profits are included in the condensed consolidated financial statements of the Company and Southwest and were not eliminated during consolidation in accordance with accounting treatment for rate-regulated entities.

Accounts Receivable, net of allowances. Business activity with respect to natural gas utility operations is conducted with customers located within the 3-state region of Arizona, Nevada, and California. Southwest’s accounts receivable are short-term in nature with no billing due dates customarily extending beyond one month, with customers’ credit worthiness assessed upon account creation by evaluation of other utility service and related payment history. Although Southwest seeks to minimize its credit risk related to utility operations by requiring security deposits from new customers, imposing late fees, and actively pursuing collection on overdue accounts, some accounts are ultimately not collected. Customer accounts are subject to collection procedures that vary by jurisdiction (late fee assessment, noticing requirements for disconnection of service, and procedures for actual disconnection and/or reestablishment of service). After disconnection of service, accounts are customarily written off approximately two months after inactivation. Dependent upon the jurisdiction, reestablishment of service requires both payment of previously unpaid balances and additional deposit requirements. Provisions for uncollectible accounts are recorded monthly based on experience, consideration of current and expected future conditions, customer and rate composition, and write-off processes. They are included in the ratemaking process as a cost of service. The Nevada jurisdictions have a regulatory mechanism associated with the gas-cost-related portion of uncollectible accounts. Such amounts are deferred and collected through a surcharge in the ratemaking process. Due to the ongoing COVID-19 pandemic, Southwest continued the moratorium initiated in March 2020 on disconnection of natural gas service for non-payment and also ceased charging late fees until further notice. While the moratorium continues to be in place, Southwest is actively working with customers experiencing financial hardship by means of flexible payment options. Management continues to monitor expected credit losses in light of the evolving financial impact of COVID-19. The allowance as of September 30, 2020 reflects the expected impact from the pandemic on balances as of that date, including consideration of customers’ ability to pay currently and once the moratorium is lifted.

SOUTHWEST GAS HOLDINGS, INC.						Form 10-Q
SOUTHWEST GAS CORPORATION						September 30, 2020

Utility infrastructure services contracts receivable are recorded at face amounts less an allowance for doubtful accounts. Centuri’s customers are generally investment-grade gas and electric utility companies for which Centuri has historically recognized an insignificant amount of write-offs. Centuri’s trade accounts receivable balances carry standard payment terms of up to 60 days. Centuri maintains an allowance that is an estimate based on historical collection experience, current and estimated future economic and market conditions, and a review of the current status of each customer's trade accounts receivable balance. Account balances are monitored at least monthly, and are charged off against the allowance when management determines it is probable the balance will not be recovered. Centuri has not been significantly impacted, nor does it anticipate it will experience significant difficulty in collecting amounts due, as a result of the current environment surrounding COVID-19 given the nature of its customers.

Activity between periods in the allowance for uncollectibles and the balances as of the periods presented within the Company’s and Southwest’s financial statements were not material to the condensed consolidated financial statements overall.

Income Taxes. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act was enacted. The CARES Act provides a number of tax provisions and stimulus measures, including changes to prior and future limitations on interest deductions, the ability to accelerate refund of Alternative Minimum Tax credits, elective deferment of payment related to the employer portion of Social Security taxes, and the creation of certain refundable employee retention credits, among other things. Management does not anticipate the impacts related to the CARES Act to have a material effect on the Company’s or Southwest’s results of operations, financial position, or liquidity.

Prepaid and other current assets. Prepaid and other current assets includes gas pipe materials and operating supplies of $55 million at September 30, 2020 and $57 million at December 31, 2019 (carried at weighted average cost), in addition to $33 million at December 31, 2019 related to a regulatory asset associated with the Arizona decoupling mechanism (an alternative revenue program), with no corresponding asset balance at September 30, 2020.

Goodwill. Goodwill is assessed as of October 1st each year for impairment, or more frequently, if circumstances indicate an impairment to the carrying value of goodwill may have occurred. Management of the Company and Southwest considered its reporting units and segments and determined that its segments and reporting units remain consistent between periods presented below, and that no change was necessary with regard to the level at which goodwill is assessed for impairment. Since December 31, 2019, management also qualitatively assessed whether events during the first nine months of 2020 may have resulted in conditions whereby the carrying value of goodwill was higher than its fair value, which if the case, could be an indication of a permanent impairment. Through this assessment, no such condition was believed to have existed and therefore, 0 impairment was deemed to have occurred. Goodwill on Southwest’s and the Company’s Condensed Consolidated Balance Sheets includes:


(Thousands of dollars)	Natural Gas Operations		Utility Infrastructure Services		Total Company

September 30, 2020	$	10,095	$	330,102	$	340,197

Other Current Liabilities. Management recognizes in its balance sheets various liabilities that are expected to be settled through future cash payment within the next twelve months, including amounts payable under regulatory mechanisms, customary accrued expenses for employee compensation and benefits, declared but unpaid dividends, and miscellaneous other accrued liabilities. Other current liabilities for Southwest includes $27 million and $25.2 million of dividends declared by Southwest Gas Corporation, but not yet paid to Southwest Gas Holdings, Inc. as of September 30, 2020 and December 31, 2019, respectively.

Included in the table above is the change in cash surrender values of COLI policies (including net death benefits recognized). Current tax regulations provide fortax-free treatment of life insurance (death benefit) proceeds. Therefore, changes in the cash surrender values of COLI policies, as they progress towards the ultimate death benefits, are also recorded without tax consequences.

~~Recently Issued Accounting Standards Updates.~~ Refer to Other Property and Investments above and also to Note 2 – Components of Net Periodic Benefit Cost.

Derivatives. In ~~May 2014,~~managing its natural gas supply portfolios, Southwest has historically entered into fixed- and variable-price contracts, which qualify as derivatives. Additionally, Southwest has utilized fixed-for-floating swap contracts (“Swaps”) to supplement its fixed-price contracts. The fixed-price contracts, firm commitments to purchase a fixed amount of gas in the ~~FASB issued~~future at a fixed price, qualify for the ~~update “Revenue~~normal purchases and normal sales exception that is allowed for contracts that are probable of delivery in the normal course of business, and are exempt from ~~Contracts with Customers (Topic 606).”~~fair value reporting. The ~~update replaces much~~variable-price contracts qualify as derivative instruments; however, because the contract prices are the prevailing prices at the future transaction dates, the contracts have no determinable fair value. The Swap contract prices are determined at the beginning of each month to reflect that month’s published first of month index price and are recorded at fair value (Level 2). Southwest does not utilize derivative financial instruments for speculative purposes, nor does it have trading operations.

Management does not currently anticipate entering into new Swaps in the near term; the remaining Swaps as of September 30, 2020 matured in October 2020.

Previously, Southwest entered into 2 forward-starting interest rate swaps (“FSIRS”). One of the FSIRS became fully amortized in the current ~~guidance regarding revenue recognition including most industry-specific guidance.~~ quarter with one FSIRS remaining to be amortized through 2022. The settled position for the remaining FSIRS is immaterial and will continue to be amortized from Accumulated other comprehensive income (loss) into interest expense.

Redeemable Noncontrolling Interest. In ~~accordance~~connection with the ~~update, an entity will be required to identify~~acquisition of Linetec in November 2018, the ~~contract with~~previous owner retained a 20% equity interest in Linetec, the customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract, and recognize revenue when (or as) the entity satisfies a performance obligation. In addition to the new revenue recognition requirements, entities will be required to disclose sufficient information to enable usersreduction of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. Entities may choose between two retrospective transition methods when applying the update. In July 2015, the FASB approved a~~one-year~~ deferral of the effective date (annual periods beginning after December 15, 2017). In March, April, May, and December of 2016, the FASB issued updates to Topic 606 related to “Principal versus Agent Considerations (Reporting Revenue Gross versus Net)”, “Identifying Performance Obligations and Licensing,” “Narrow-Scope Improvements and Practical Expedients”, and certain “Technical Corrections and Improvements.” The amendments in the first two updates, respectively, provide guidance when another party, along with the entity, is involved in providing a good or service to a customer, and provide clarification with regard to identifying performance obligations and of the licensing implementation guidance in Topic 606. The third update includes improvements to the guidance on collectibility, noncash consideration, and completed contracts at transition. In addition, a practical expedient is provided for contract modifications at transition and an accounting policy election related to the presentation of sales taxes and other similar taxes collected from customers. The fourth update affects narrow aspects of the guidance as issued to date. Management plans to adopt all of these updates at the required adoption date, which is ~~for interim and annual reporting periods commencing January 2018.~~

~~Deliberations have been ongoing by~~subject to certain rights based on the ~~utility industry, notably in connection with efforts to produce an accounting guide intended to be developed by~~passage of time or upon the ~~American Institute~~occurrence of Certified Public Accountants (“AICPA”). In association with this undertaking, the AICPA formed a number of industry task forces, including a Power & Utilities (“P&U”) Task Force, on which Company personnel actively participate via formal membership. Industry representatives and organizations, the largest auditing firms, the AICPA’s Revenue Recognition Working Group and its Financial Reporting Executive Committee have undertaken, and continue to undertake, consideration of several items relevant to the utility industry. Where applicable or necessary, the FASB’s Transition Resource Group (“TRG”) has also participated. Through the P&U Task Force undertakings, general determinations were made that contributions received in aid of construction (“CIAC”) efforts related to the industry’s pipe distribution and transmission systems are reimbursements of expenditures rather than revenue (consistent with current accounting practices). Furthermore, regarding the “collectibility” criterion in the update that must be met for revenue recognition, general determinations have been made that contracts for utility service (including service to lower income or lower credit quality customers)

certain triggering events.


~~SOUTHWEST GAS HOLDINGS, INC.~~		16	~~Form 10-Q~~
~~SOUTHWEST GAS CORPORATION~~	~~September 30, 2017~~

represent genuine and valid contracts for which revenue is able to be recognized when service is rendered (consistent with current accounting practices). These determinations by the P&U industry are based on the various measures the industry takes to help ensure collectibility (e.g., proof of creditworthiness, customer deposits, late fee assessment, disconnection, service~~re-establishment~~ fees, collection processes, etc.), in addition to the regulatory mechanisms established under rate regulation to mitigate the impacts of individual customer nonpayment. Southwest has also actively worked with its peers in the rate-regulated natural gas industry and with the public accounting profession to finalize the accounting treatment for several other issues not separately addressed by the P&U Task Force.

With regard to the construction services segment, the principles of the new revenue recognition guidance are very similar to existing guidance for construction contractors. Similar to the P&U Task Force noted above, the AICPA formed the Engineering and Construction Contractors Task Force to assist the construction industry with implementing the new guidance. The accounting guide the AICPA intends to release is expected to provide implementation guidance related to several issues including 1) combining contracts and separating performance obligations; 2) estimating change orders, incentives, penalties, liquidated damages and other variable consideration items and 3) acceptable measures of progress when recognizing revenue over time.

Management of both segments of the Company has substantially completed assessments of sources of revenue and the effects that adoption of the new guidance will have on the Company’s (and Southwest’s in the case of utility operations) financial position, results of operations, and cash flows. Based on assessments completed to date, management believes that such impacts will not be material overall. Presentation and disclosure requirements of the new guidance will have the most impact on the Company’s financial statements and note disclosures. The Company is currently planning to adopt the new guidance in 2018 under the modified retrospective transition method, as permissible.

~~In January 2016, the FASB issued the update “Financial Instruments – Overall (Subtopic825-10):~~ Recognition and Measurement of Financial Assets and Financial Liabilities” in order to improve the recognition and measurement of financial instruments. The update makes targeted improvements to existing U.S. GAAP by: 1) requiring equity investments to be measured at fair value with changes in fair value recognized in net income; 2) requiring the use of the exit price notion when measuring the fair value of financial instruments for disclosure purposes; 3) requiring separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements; 4) eliminating the requirement to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet; and 5) requiring a reporting entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in instrument-specific credit risk when the organization has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. The update is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. All entities can early adopt the provision to record fair value changes for financial liabilities under the fair value option resulting from instrument-specific credit risk in other comprehensive income. Management believes this update will not have a material impact on its consolidated financial statements and disclosures.

In February 2016, the FASB issued the update “Leases (Topic 842).” Under the update, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date:

~~A lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and~~

A~~right-of-use~~ ~~asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term.~~

Under the new guidance, lessor accounting is largely unchanged. Certain targeted improvements were made to align, where necessary, lessor accounting with the lessee accounting model and Topic 606, Revenue from Contracts with Customers. Though companies have historically been required to make disclosures regarding leases and of associated contractual obligations, leases (with terms longer than a year) will no longer exist~~off-balance~~ sheet. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply

Recent Accounting Standards Updates.

Accounting pronouncements adopted in light of its customary leasing arrangements (and other arrangements in association with the new guidance) to determine the effect the new standard will have on its financial position, results of operations, cash flows, and business processes.

2020:

In June 2016, the ~~FASB~~Financial Accounting Standards Board (the “FASB”) issued ~~the~~ASU 2016-13 update “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” The update ~~amends guidance on reporting~~requires the measurement of all expected credit losses for financial assets held at ~~amortized cost basis~~the reporting date based on historical experience, current conditions, and ~~available for sale debt securities. For assets held at amortized cost basis,~~reasonable and supportable forecasts. The Company and Southwest adopted the update ~~eliminates~~in the ~~“probable” threshold for initial recognition~~first quarter of ~~credit losses in current U.S. GAAP~~2020, and ~~instead, requires an entity~~concluded the impact was not material to ~~reflect its current estimate of all expected credit losses. The allowance for credit losses is a valuation account that is deducted from~~ the amortized cost basis of the financial asset to present the net amount expected to be collected. For available for sale debt securities, credit losses should be measured in a manner similar to current U.S. GAAP, however the update will require that credit losses be presented as an allowance rather than as a write-down. This update affects entities holding financial assets and net investment in leases that are not accounted for at fair value through net income. The update affects loans, debt securities, trade receivables, net investments in leases,~~off-balance~~ sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope that have the contractual right to receive cash. The update is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. All entities may adopt the amendments in this update earlier as of fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Management is evaluating what impact, if any, this update might have on its consolidated financial statements ~~and disclosures.~~

In August 2016, the FASB issued the update “Classification of Certain Cash Receipts and Cash Payments.” This update addresses the following specific cash flow issues: debt prepayment or debt extinguishment costs; settlement of~~zero-coupon~~ ~~debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate~~ of the ~~borrowing; contingent consideration payments made after a business combination; proceeds from the settlement~~Company or Southwest. See Accounts receivable, net of insurance claims; proceeds from the settlement of corporate-owned life insurance (“COLI”) policies; distributions received from equity method investees; beneficial interests in securitization transactions; and separately identifiable cash flows, including identification of the predominant nature in cases where cash receipts and payments have aspects of more than one class of cash flows. The update is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. Management believes this update will not have a material impact on its consolidated cash flow statements and disclosures.

In October 2016, the FASB issued the update “Accounting for Income Taxes: Intra-Entity Asset Transfers of Assets Other than Inventory.” This update eliminates the current U.S. GAAP exception for all intra-entity sales of assets other than inventory. As a result, a reporting entity would recognize the tax expense from the sale of the asset in the seller’s tax jurisdiction when the transfer occurs, even though the~~pre-tax~~ effects of that transaction are eliminated in consolidation. Any deferred tax asset that arises in the buyer’s jurisdiction would also be recognized at the time of the transfer. The update is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted; however, the guidance can only be adopted in the first interim period of a fiscal year. No such election to adopt early was made by management. The modified retrospective approach will be required for transition to the new guidance, with a cumulative-effect adjustment recorded in retained earnings as of the beginning of the period of adoption. Management believes this update will not have a material impact on its consolidated financial statements and disclosures.

Recently issued accounting pronouncements that will be effective after 2020:

In December 2019, the FASB issued ASU 2019-12 “Income Taxes (Topic 740): Simplifying the Accounting for ~~a reporting unit~~Income Taxes.” The update simplifies the accounting for income taxes by removing certain exceptions to ~~determine if~~ the ~~quantitative impairment test is necessary. The amendments should be applied on a prospective basis.~~general principles, as well as improving consistent application in Topic 740 by clarifying and amending existing guidance. The update is effective for fiscal ~~and interim periods~~years beginning after December 15, ~~2019.~~2021, and interim periods within fiscal years beginning after December 15, 2022. Early adoption is permitted for ~~interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. Management has determined that this update would have had no impact on the consolidated~~periods for which financial statements ~~for the periods presented if it had been effective during those periods.~~

In March 2017, the FASB issued the update “Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” The update applies to all employers that offer employee benefits under defined benefit pension plans, other postretirement benefit plans, or other types of benefits accounted for under Topic 715, Compensation – Retirement Benefits. The update requires that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, and be appropriately described. The update also allows only the service cost component (and not the other components of periodic benefit costs) to be eligible for capitalization when applicable, making no exception for specialized industries, including~~rate-regulated~~ ~~industries.~~

Southwest is a rate-regulated utility offering pension and postretirement benefits to retired employees. It is anticipated that Southwest would continue to request recovery of the total costs of defined benefit plans in rate applications filed with its various regulatory bodies. Rate-regulated entities providing utility and transmission services have ~~historically capitalized a portion of periodic benefit costs (includingnon-service~~ cost components) in utility infrastructure (for instance, when productive labor is also charged to capital work orders). The portion capitalized has historically been a component of depreciation and related rate development through efforts of companies and their regulatory commissions. The Federal Energy Regulatory Commission (“FERC”) regulates interstate transmission pipelines and also establishes, via its Uniform System of Accounts, accounting practices of rate-regulated entities. Accounting guidelines by the FERC are typically also upheld by state commissions. Historically, those guidelines have been generally consistent with guidance in U.S. GAAP (including U.S. GAAP for rate-regulated entities). While formal guidance has not yet been ~~published by the FERC, it~~made available for issuance. Management is ~~currently believed that the FERC will permit an election to either continue to capitalizenon-service~~ benefit costs for regulatory reporting purposes or to cease capitalizing such costs and implement the Topic 715 update capitalization provisions “as is,” for regulatory purposes. Assuming the FERC formalizes the above elections, Southwest currently anticipates adopting the provisions of Topic 715 for both SEC reporting and regulatory purposes. Industry deliberations continue and management will be evaluating the ~~various~~ impacts this update ~~will~~might have on ~~its~~the Company’s and Southwest’s consolidated financial statements and disclosures. It

In March 2020, the FASB issued ASU 2020-04 “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” The update provides optional guidance for a limited time to ease the potential burden in accounting for, or recognizing the effects of, reference rate reform on financial reporting, including when modifying a contract (during the eligibility period covered by the update to Topic 848) to replace a reference rate affected by reference rate reform. The update applies only to contracts and hedging relationships that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued due to reference rate reform. The guidance was eligible to be applied upon issuance on March 12, 2020, and can generally be applied through December 31, 2022. Management will monitor the impacts this update might have on the Company’s and Southwest’s consolidated financial statements and disclosures, and will reflect such appropriately, in the event that the optional guidance is ~~estimated that approximately $3 million~~elected. See also LIBOR discussion in~~non-service~~ ~~costs were capitalized as a component of gas plant during 2016. Totalnon-service~~ ~~costs were approximately $20 million~~Note 5 – Debt.

In August 2020, the FASB issued ASU 2020-06 “Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging— Contracts in ~~2016.~~

Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity.” The update, amongst other amendments, improves the guidance related to the disclosures and earnings-per-share for convertible instruments and contracts in an entity’s own equity. The update is effective for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years; early adoption is permitted. Management is evaluating the impacts this update might have on the Company’s consolidated financial statements and disclosures.

Note 2 – Components of Net Periodic Benefit Cost

Southwest has a noncontributory qualified retirement plan with defined benefits covering substantially all employees and a separate unfunded supplemental retirement plan (“SERP”) which is limited to officers. Southwest also provides postretirement benefits other than pensions (“PBOP”) to its qualified retirees for health care, dental, and life insurance.

~~Net~~

The service cost component of net periodic benefit costs included in the table below ~~are components~~is a component of an overhead loading process associated with the cost of labor. The overhead process ultimately results in allocation of that portion of overall net periodic benefit costs to the same accounts to which productive labor is charged. As a result, ~~net periodic benefit~~service costs become components of various accounts, primarily operations and maintenance expense, net utility plant, and deferred charges and other assets for both the Company and Southwest.

Previously, Southwest entered into two forward-starting interest rate swaps (“FSIRS”), both of which were designated cash flow hedges, to partially hedge the risk of interest rate variability during the period leading up to the planned issuance of debt. The first FSIRS terminated in December 2010. The second FSIRS terminated in March 2012. Losses on both FSIRS are being amortized over~~ten-year~~ ~~periods from Accumulated other comprehensive income (loss) into interest expense.~~

The estimated fair values of the natural gas derivatives were determined using future natural gas index prices (as more fully described below). Master netting arrangements exist with each counterparty that provide for the net settlement (in the settlement month) of all contracts through a single payment. As applicable, management has elected to reflect the net amounts in its balance sheets. There was no outstanding collateral associated with the Swaps during either period shown in the above table.

Pursuant to regulatory deferral accounting treatment for rate-regulated entities, unrealized gains and losses in fair value of the Swaps are recorded as a regulatory asset and/or liability. When the Swaps mature, any prior positions held are reversed and the settled position is recorded as an increase or decrease of purchased gas under the related purchased gas adjustment (“PGA”) mechanism in determining its deferred PGA balances. Neither changes in fair value, nor settled amounts, of Swaps have a direct effect on earnings or other comprehensive income.

~~The following table shows the amounts Southwest paid to and received from counterparties for settlements of matured Swaps.~~

~~Fair Value Measurements.~~ The estimated fair values of Southwest’s Swaps were determined at September 30, 2017 and December 31, 2016 using New York Mercantile Exchange (“NYMEX”) futures settlement prices for delivery of natural gas at Henry Hub adjusted by the price of NYMEX ClearPort basis Swaps, which reflect the difference between the price of natural gas at a given delivery basin and the Henry Hub pricing points. These Level 2 inputs (inputs, other than quoted prices, for similar assets or liabilities) are observable in the marketplace throughout the full term of the Swaps, but have been credit-risk adjusted with no significant impact to the overall fair value measurement.

The following table sets forth, by level within the three-level fair value hierarchy that ranks the inputs used to measure fair value by their reliability, the financial assets and liabilities that were accounted for at fair value by both the Company and Southwest:

The following table provides information about contracts receivable and revenue earned on contracts in progress in excess of billings (contract asset), which are both included within Accounts receivable, net of allowances, as well as amounts billed in excess of revenue earned on contracts (contract liability), which are included in Other current liabilities as of September 30, 2020 and December 31, 2019 on the Company’s Condensed Consolidated Balance Sheets:


(Thousands of dollars)	September 30, 2020		December 31, 2019
Contracts receivable, net	$	275,598	$	223,904
Revenue earned on contracts in progress in excess of billings	156,754		99,399
Amounts billed in excess of revenue earned on contracts	5,522		4,525

The revenue earned on contracts in progress in excess of billings (contract asset) primarily relates to Centuri’s rights to consideration for work completed but not billed and/or approved for billing at the reporting date. These contract assets are transferred to contracts receivable when the rights become unconditional. The amounts billed in excess of revenue earned (contract liability) primarily relate to the advance consideration received from customers for which work has not yet been completed. The change in this contract liability balance from December 31, 2019 to September 30, 2020 is due to revenue recognized of$4.5 millionthat was included in this item as of January 1, 2020, after which time it became earned and the balance was reduced, and to increases due to cash received, net of revenue recognized during the period related to contracts that commenced during the period.

For contracts that have an original duration of one year or ~~liabilities associated with~~less, Centuri uses the ~~Swaps, which were accounted for at fair~~practical expedient applicable to such contracts and does not consider/compute an interest component based on the time value ~~fell within Level 1 (quoted prices in active markets for identical financial assets) or Level 3 (significant unobservable inputs)~~of money. Further, because of the ~~fair value hierarchy.~~

~~With regard~~short duration of these contracts, Centuri has not disclosed the transaction price for the remaining performance obligations as of the end of each reporting period or when the Company expects to recognize the revenue.

As of September 30, 2020, Centuri had 23 contracts with an original duration of more than one year. The aggregate amount of the transaction price allocated to the ~~fair values~~unsatisfied performance obligations of ~~assets associated with pension and postretirement benefit plans, asset values were last updated as required~~these contracts as of ~~December 2016. Refer~~September 30, 2020 was $55.3 million. Centuri expects to recognize the remaining performance obligations over approximately the next year; however, the timing of that recognition is largely within the control of the customer, including when the necessary equipment and materials required to complete the work are provided by the customer.

Utility infrastructure services contracts receivable consists of the following:

Long-Term Debt

~~Carrying amounts~~

Long-term debt is recognized in the Company’s and Southwest’s Condensed Consolidated Balance Sheets generally at the carrying value of ~~long-term debt~~the obligations outstanding. However, details surrounding the fair value and ~~related estimated~~individual carrying values of instruments are discussed below or provided in the table that follows.

The fair values as of ~~September 30, 2017 and December 31, 2016 are disclosed in the following table.~~ Southwest’s revolving credit facility (including commercial paper) and the variable-rate Industrial Development Revenue Bonds (“IDRBs”) approximate their carrying values. The fair values ~~as they are repaid quickly (in~~of the ~~case of~~revolving credit facility ~~borrowings)~~ and ~~have interest rates that reset frequently. These~~IDRBs are categorized as Level 1 based on the FASB’s fair value hierarchy, due to Southwest’s ability to access similar debt arrangements at measurement dates with comparable terms, including variable/market rates. Additionally, the borrowings by Southwest under its revolving credit facility are generally repaid quickly and the IDRBs have interest rates that reset frequently.

The fair values of Southwest’s debentures (which include senior ~~notes,~~ and ~~fixed-rate IDRBs~~medium-term notes) were determined utilizing a market-based valuation approach, where fair values are determined based on evaluated

pricing data, such as broker quotes and yields for similar securities adjusted for observable differences. Significant inputs used in the valuation generally include benchmark yield curves, credit ratings, and issuer spreads. The external credit rating, coupon rate, and maturity of each security are considered in the valuation, as applicable. The fair values of debentures ~~and fixed-rate IDRBs~~ are categorized as Level ~~2 (observable market inputs based on market prices of similar securities).~~ 2.

The Centuri secured revolving credit and term loan facility and ~~Centuri~~Centuri’s other debt obligations (not actively traded) are categorized as Level ~~3, based on significant unobservable inputs to their fair values.~~3. Because Centuri’s debt is not publicly traded, fair values for ~~the~~its secured revolving credit and term loan facility and other debt obligations were based on a conventional discounted cash flow methodology ~~and utilized~~utilizing current market pricing yield curves, across Centuri’s debt maturity spectrum, of other industrial bonds with an assumed credit rating comparable to the Company’s.

loans bearing interest with reference to the alternative base rate. At September 30, ~~2017, $150~~2020, $58 million was outstanding on the long-term portion ~~and $83~~(including $50 million ~~was outstanding on~~under the ~~short-term portion~~commercial paper program, discussed below) of ~~this~~the facility.

On April 10, 2020, Southwest amended its credit facility ~~(See~~~~Note 7 – Short-Term Debt~~).

At September 30, 2017, Centuri has a $300 million secured revolving credit and term loan facility that is scheduled to expire in October 2019. This facility includes a revolving credit facility and a term loan facility. The term loan facility portion had an initial limit of approximately $150 million, which was reached in 2014 and had $107 million outstanding (after repayments) at September 30, 2017. The $300 million revolving credit and term loan facility is secured by substantially all of Centuri’s assets except those explicitly excludedagreement; total borrowing capacity under the ~~terms of~~amended agreement remains at $400 million. The amended agreement extended the maturity date from March 2022 to April 2025. Under the amended agreement, ~~(including owned real estate and certain certificated vehicles). Centuri assets securing~~ the ~~facility at September 30, 2017 totaled $526 million. At September 30, 2017, $189 million in borrowings were outstanding under the Centuri facility.~~

~~Note 7 – Short-Term Debt~~

In March 2017, Southwest Gas Holdings, Inc. entered into a credit facility with a borrowing capacity of $100 million that expires in March 2022. The Company intends to utilize this facility for short-term financing needs. Interest rates for this facility are calculated at either the LIBOR or the “alternate base rate,” plus in each case an applicable margin ~~that is determined based on the Company’s senior unsecured debt rating. The applicable margin ranges~~will range from ~~0.75%~~0.750% to ~~1.50%~~1.500% for loans bearing interest with reference to LIBOR and from 0%0.000% to ~~0.5%~~0.500% for loans bearing interest with reference to ~~the alternative~~an alternate base rate. ~~The Company~~Upon the occurrence of certain events providing for a transition away from LIBOR, or if LIBOR is no longer a widely recognized benchmark rate, Southwest may further amend the credit facility with a replacement rate as set forth in the amended agreement. Southwest is also required to pay a commitment fee on the unfunded portion of the commitments based on its senior unsecured long-term debt rating. The commitment fee ranges from 0.075% to 0.200% per annum. The amended agreement contains certain representations and warranties and affirmative and negative covenants similar to those contained in the previous agreement. In addition, the amended agreement contains a financial covenant requiring Southwest to maintain a ratio of funded debt to total capitalization not to exceed 0.70 to 1.00 as of the end of any quarter of any fiscal year.

Southwest has a $50 million commercial paper program. Issuances under the commercial paper program are supported by Southwest’s revolving credit facility and, therefore, do not represent additional borrowing capacity under the credit facility. Borrowings under the commercial paper program are designated as long-term debt. Interest rates for the program are calculated at the then current commercial paper rate. At September 30, ~~2017, $27.5~~2020, as noted above, $50 million ~~was~~ of borrowings were outstanding under ~~this facility.~~

~~As discussed~~the commercial paper program.

In June 2020, Southwest issued $450 million aggregate principal amount of 2.20% Senior Notes at a discount of 0.126%. The notes will mature in~~Note 6 – Long-Term Debt~~, June 2030. A portion of the net proceeds was used to reduce borrowings under Southwest’s credit facility and to redeem the 4.45% $125 million Notes due in December 2020, which were redeemed in September 2020 after Southwest provided advance notice to the holders of its intention to redeem the notes in full at a redemption price of 100% plus accrued and unpaid interest.

Centuri has a ~~$400~~$590 million senior secured revolving credit and term loan facility, scheduled to expire in November 2023. The capacity of the line of credit portion of the facility is $325 million; related amounts borrowed and repaid are available to be re-borrowed. The term loan portion of the facility has a limit of approximately $265 million. The $590 million facility is secured by substantially all of Centuri’s assets except those explicitly excluded under the terms of the agreement (including owned real estate and certain certificated vehicles). Centuri’s assets securing the facility at September 30, 2020 totaled $1.4 billion. At September 30, 2020, $291 million in borrowings were outstanding under Centuri’s combined secured revolving credit and term loan facility. During 2020, Centuri also received proceeds of $70 million in equipment loans, which were used for repayment of outstanding borrowings on the line of credit.

Short-Term Debt

Southwest Gas Holdings, Inc. has a $100 million credit facility that is ~~scheduled~~primarily used for short-term financing needs. There was $54 million outstanding under this credit facility as of September 30, 2020.

Similar to ~~expire~~Southwest amending its credit facility agreement, on April 10, 2020, Southwest Gas Holdings, Inc. also amended its existing credit facility, extending the maturity date to April 2025. The revolving borrowing capacity under the amended agreement remained at $100 million, the same as before the amendment. Interest rate benchmarks (LIBOR or an alternative) as well as related ranges, including with regard to the applicable margin, largely mirror those included in ~~March 2022,~~Southwest’s amended facility agreement noted above, determined in this case based on Southwest Gas Holdings, Inc.’s senior unsecured long-term debt rating. Similar to the Southwest facility amendment, upon the occurrence of ~~which~~certain events providing for a transition away from LIBOR, or if LIBOR is no longer a widely recognized benchmark rate, Southwest Gas Holdings, Inc. may amend its credit facility agreement with a replacement rate, as set forth in the amended agreement. The commitment fee rates, terms, and covenants, noted above for Southwest are also applicable to Southwest Gas Holdings, Inc. in its amended credit facility, including the noted ratio of funded debt to total capitalization as of the end of any quarter of any fiscal year.

As discussed previously, under Southwest’s $400 million credit facility, $250 million has been designated by management for working capital purposes. Southwest had ~~$83 million in~~0 short-term borrowings outstanding at September 30, ~~2017~~2020 under this facility.

LIBOR

It is currently anticipated that LIBOR may be discontinued as a benchmark or reference rate after 2021. As of September 30, 2020, $54 million, $8 million and $172 million, respectively, for the holding company, Southwest, and Centuri, were outstanding under credit facilities whereby interest was with reference to LIBOR and for which facility maturity dates extend beyond 2021. As of September 30, 2020, these LIBOR-based borrowings represent approximately 0.3% of Southwest’s total debt, and 8% of total debt (including current maturities) for the Company overall. Southwest and Southwest Gas Holdings, Inc., in accordance with the April 2020 amendments to their respective facilities, may make further amendments with replacement rates if LIBOR is discontinued. However, replacement rates are not currently determinable. In order to mitigate the impact of a discontinuance on the Company’s and Southwest’s financial condition and results of operations, management will continue to monitor developments and work with lenders to determine the appropriate replacement/alternative reference rate for variable rate debt. At this time the Company and Southwest can provide no assurances as to the impact a LIBOR discontinuance will have on their financial condition or results of operations. Any alternative rate may be less predictable or less attractive than LIBOR.

(1)Tax amounts are calculated using a 24% rate. The Company has elected to indefinitely reinvest the earnings of Centuri’s Canadian subsidiaries in Canada, thus precluding deferred taxes on such earnings. As a result of this assertion, and no repatriation of earnings anticipated, the Company is not recognizing a tax effect or presenting a tax expense or benefit for currency translation adjustments reported in Other comprehensive income (loss).

Approximately ~~$2.1~~$1.7 million of realized losses (net of tax) related to the ~~FSIRS, reported~~remaining balance of Southwest’s forward-starting interest rate swaps (“FSIRS”), included in ~~Accumulated other comprehensive income (“AOCI”)~~AOCI at September 30, ~~2017,~~2020, will be reclassified into interest expense within the next 12 months as the related interest payments on long-term debt occur.

~~Note 9 – Construction Services Redeemable Noncontrolling Interest~~

In conjunction with the acquisition of the Canadian construction businesses in October 2014, the previous owners of the acquired companies retained a 3.4% equity interest in Centuri, which, subject to an eligibility timeline, would have been redeemable at the election of the noncontrolling parties (in its entirety) beginning in July 2022. In August 2017, in advance of when otherwise eligible, the parties agreed to a current redemption. Southwest Gas Holdings, Inc. paid $23 million to the previous owners, thereby acquiring the remaining 3.4% equity interest in Centuri in accordance with an early redemption agreement. Accordingly, Centuri is now a wholly owned subsidiary of the Company.

~~Note 10 – Reorganization Impacts – Discontinued Operations Solely Related to Southwest Gas Corporation~~

No substantive change has occurred with regard to the Company’s business segments on the whole, or in the primary businesses comprising those segments (Centuri operations continue to be part of continuing operations of the controlled group of companies), and financial information related to Centuri continues to be included in condensed consolidated financial statements of Southwest Gas Holdings, Inc.

However, as part of the holding company reorganization effective January 2017, Centuri is no longer a subsidiary of Southwest; whereas historically, Centuri had been a direct subsidiary of Southwest. To give effect to this change, the condensed consolidated financial statements related to Southwest Gas Corporation, which are separately included in this~~Form 10-Q,~~ ~~depict Centuri-related amounts as discontinued operations for periods prior to January 2017.~~

Due to the discontinued operations accounting reflection, the following disclosures provide additional information regarding the assets, liabilities, equity, revenues, and expenses of Centuri which are shown as discontinued operations on the condensed consolidated financial statements of Southwest Gas Corporation for periods prior to the beginning of 2017.

SOUTHWEST GAS CORPORATION						September 30, ~~2017~~2020

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Southwest Gas Holdings, Inc. is a holding company that owns all of the shares of common stock of Southwest Gas Corporation (“Southwest” or the “natural gas operations” segment) and ~~prior to August 2017, 96.6%~~all of the shares of common stock of Centuri ~~Construction~~ Group, Inc. (“~~Centuri”~~Centuri,” or the ~~“construction~~“utility infrastructure services” segment). During August 2017, Southwest Gas Holdings, Inc. acquired the remaining 3.4% equity interest in Centuri that was held by the previous owners (and reflected as a redeemable noncontrolling interest). Therefore, Centuri is now a wholly owned subsidiary of Southwest Gas Holdings, Inc. Also, as part of the holding company reorganization effective January 2017, Centuri and Southwest are now subsidiaries of Southwest Gas Holdings, Inc.; whereas historically, Centuri had been a direct subsidiary of Southwest. Southwest Gas Holdings, Inc. and its subsidiaries ~~(the “Company”) have two business segments (natural gas operations and construction services), which~~ are ~~discussed below.~~

collectively referred to as the “Company.”

Southwest is engaged in the business of purchasing, distributing, and transporting natural gas for customers in portions of Arizona, Nevada, and California. Southwest is the largest distributor of natural gas in Arizona, selling and transporting natural gas in most of central and southern Arizona, including the Phoenix and Tucson metropolitan areas. Southwest is also the largest distributor of natural gas in Nevada, serving the majority of southern Nevada, including the Las Vegas metropolitan area, and portions of northern Nevada. In addition, Southwest distributes and transports natural gas for customers in portions of California, including the Lake Tahoe area and the high desert and mountain areas in San Bernardino County.

As of September 30, ~~2017 (on a seasonally adjusted basis),~~2020, Southwest had ~~1,999,000~~2,112,000 residential, commercial, industrial, and other natural gas customers, of which ~~1,065,000~~1,126,000 customers were located in Arizona, ~~741,000~~786,000 in Nevada, and ~~193,000~~200,000 in California. Over the past twelve months, first time meter sets were approximately 37,000, compared to 34,000 for the twelve months ending September 2019. The remaining increase in active customer accounts compared to the September 30, 2019 total of 2,066,000 was primarily due to a management-initiated moratorium on disconnections as a result of the COVID-19 pandemic. As utility service is an essential service to the residents in the states in which Southwest operates, it implemented the moratorium in March 2020 and also ceased charging late fees until further notice. The duration of our moratorium is currently uncertain. Residential and small commercial customers represented over 99% of ~~the~~the total customer base. During the twelve months ended September 30, ~~2017, 54%~~2020, 53% of ~~operating margin was earned in Arizona, 35% in Nevada, and 11% in California. During this same period, Southwest earned 85% of its~~ operating margin (gas operating revenues less the net cost of gas sold) was earned in Arizona, 36% in Nevada, and 11% in California. During this same period, Southwest earned 85% of its operating margin from residential and small commercial customers, 3% from other sales customers, and 12% from transportation customers. ~~These~~While these general patterns are expected to remain materially consistent for the ~~foreseeable future.~~

foreseeable future, the global COVID-19 pandemic, as discussed further below, could impact these statistics and associated patterns in the short term.

Southwest recognizes operating revenues from the distribution and transportation of natural gas (and related services) to customers. Operating margin is a financial measure defined by management as gas operating revenues less the net cost of gas sold. However, operating margin is not specifically defined in accounting principles generally accepted in the United States (“U.S. GAAP”). Thus, operating margin is considered anon-GAAP measure. Management uses this financial measure because natural gas operating revenues include the net cost of gas sold, which is a tracked cost that is passed through to customers without markup under purchased gas adjustment (“PGA”) mechanisms. Fluctuations in the net cost of gas sold impact revenues on adollar-for-dollar basis, but do not impact operating margin or operating income. Therefore, management believes operating margin provides investors and other interested parties with useful and relevant information to analyze Southwest’s financial performance in a rate-regulated environment. The principal factors affecting changes in operating margin are general rate relief (including impacts of infrastructure trackers) and customer growth.

Commission decisions on the amount and timing of such relief may impact our earnings, such as with the current Arizona general rate case, whereby hearings were deferred amidst the current pandemic, resulting in both a decision and new rate establishment occurring later than originally expected. Refer to the Summary Operating Results table for a reconciliation of revenues to operating margin, and refer to Rates and Regulatory Proceedings in this Management’s Discussion and Analysis.

The demand for natural gas is seasonal, with greater demand in the colder winter months and decreased demand in the warmer summer months. All of Southwest’s service territories have decoupled rate structures (alternative revenue programs), which are designed to eliminate the direct link between volumetric sales and revenue, thereby mitigating the impacts of unusual weather variability and conservation on operating margin, allowing Southwest to pursue energy efficiency initiatives.

~~have implemented~~Utilities continue to implement or ~~modified pipeline~~modify system integrity management programs to enhance safety pursuant to federal and state mandates. These programs ~~coupled with recent bonus depreciation tax deduction incentives,~~ have resulted in ~~a significant increase in~~ multi-year ~~pipeline~~utility system replacement projects throughout the U.S. Generally, Centuri revenues are lowest during the first quarter of the year due to less favorable winter weather conditions. Revenues typically improve as more favorable weather conditions occur during the summer and fall months. ~~This is expected in both the U.S. and Canadian markets.~~In cases of severe weather, such as following a regional storm, Centuri may be engaged to perform restoration activities related to above-ground utility infrastructure. In certain circumstances, such as with large bid contracts (especially those of a longer duration), or unit-price contracts with revenue caps, results may be impacted by differences between costs incurred and those anticipated when the work was originally bid. Work awarded, or failing to be awarded, by individual large customers can significantly impact operating results.

COVID-19 Pandemic

In March 2020, the World Health Organization categorized the novel coronavirus (“COVID-19”) as a pandemic, and President Donald Trump declared the COVID-19 outbreak a national emergency. The outbreak resulted in government officials implementing stringent measures to help control the spread of the virus, including quarantines, “shelter in place” and “stay at home” orders, travel restrictions, business curtailments, school closures, and other measures. In addition, governments and central banks in several parts of the world enacted fiscal and monetary stimulus measures to mitigate financial impacts of COVID-19 on individuals and businesses.

Our utility operations, as essential services, have been ongoing during this time and Southwest has continued to provide services to meet the demand of its customers. Consistent with federal and state guidelines and protocols, Southwest has continued to operate across its territories. Similarly, the majority of Centuri’s largest clients issued essential service letters to Centuri businesses in keeping with the federal definition of “essential” set out by the Department of Homeland Security. This allowed Centuri to similarly continue nearly all operations from the outset of the pandemic in the U.S., and demand has not significantly diminished. The ability to work may be impacted by individuals contracting or being exposed to COVID-19, governmental requirements to postpone certain non-essential services in some of the Company’s jurisdictions, or by management imposed restrictions for safety precautions; to date, these factors have not had a significant impact on the Company’s ability to maintain operations. The Company has instructed employees at many offices (including corporate headquarters) to work from home on a temporary basis and implemented travel restrictions. Both segments implemented business continuity plans, including the deployment of technology to conduct administrative and critical functions remotely, where possible, and employees and management teams have been in place to communicate and respond to changes quickly and effectively. To date, there has not been a significant disruption in the Company’s supply chains, transportation network, or ability to serve customers.

As an essential service provider, Southwest implemented several important measures with regard to its customers. As noted above, it initiated a moratorium on natural gas disconnections for non-payment; it is working with customers who are experiencing financial hardship through flexible payment arrangements; it is coordinating with certain governmental and nonprofit entities for customer payment assistance; and it also ceased charging late fees until further notice. Management has increased the allowance for uncollectibles; however, neither this nor other measures associated with the moratorium have had a material impact on our financial position overall. As the pandemic continues into the winter season when monthly utility bills are typically higher, we expect the seasonal pattern of change in the allowance to be generally in line with historical patterns; however, the potential impact could be more significant given the pandemic. See Accounts receivable, net of allowances in Note 1 – Background, Organization, and Summary of Significant Accounting Policies. In the utility infrastructure services segment, a limited number of Centuri customers delayed some projects, notably during the second quarter, and primarily in response to local governmental restrictions. Project delays, whether due to governmental restrictions or reassessments of timing by Centuri’s customers, resulted in temporary reductions of workforce crews; such impacts were primarily limited to the second quarter of 2020. Some crew reductions are ongoing in specific areas and the associated revenue impacts have not been significant. Management is monitoring the dynamic nature of these circumstances, the full future impacts of which are not currently known, including the impact from business curtailments, weak market conditions, or governmental restrictions, including any restrictions which could limit the fulfillment by Centuri of its contractual obligations.

The Company has incurred additional expenses in connection with its response to these conditions, including costs of disinfecting work locations and equipment, costs related to enabling employees to support customers while working remotely, and impacts on earnings and cash flows from the moratorium on customer disconnection and late fee assessment. These additional costs were not material to the Company’s fiscal 2020 results to date, and were mitigated by reduced training and travel costs, as important training and business meetings were held virtually, rather than in person. Appropriate access to cash exists and certain of Southwest’s regulatory commissions have implemented measures to further mitigate impacts of these conditions on Southwest. See Rates and Regulatory Proceedings below for additional detail.

On March 27, 2020, the Coronavirus Aid, Relief and Economic Security (“CARES”) Act was enacted, as discussed in Note 1 – Background, Organization, and Summary of Significant Accounting Policies. The CARES Act to date has not, and management anticipates that it will not, have a material effect on the Company’s or Southwest’s results of operations, financial position, or liquidity. In Canada, Centuri received $4.1 million of wage subsidies (through September 30, 2020) from the Canadian government as part of a COVID-19 relief program. Management does not expect these subsidies, if any, to be significant in future periods.

The extent to which COVID-19 may adversely impact the Company’s business depends on future developments, including the timing of the resumption of commerce across our service territories, the magnitude of further spread of the virus, impacts of these conditions on our customers, the state of the North American economy, and possibly other unmitigated effects related to the virus. Management does not currently expect the impact of these conditions to be material to the Company’s liquidity and financial position; however, the continued level of uncertainty over the economic and operational impacts of COVID-19 means management cannot predict whether the related financial impact in future periods will be any different from the impacts reflected for the nine months ended September 30, 2020. In anticipation of a redeployment of employees to their normal work locations, management has created a multi-phase reintegration plan to safeguard the well-being of our teams, including hygiene, sanitization, and social distancing practices, as well as the use of personal protective equipment for employees and visitors. Management will continue to monitor developments affecting the Company’s employees, customers, and operations, and take additional steps to address the COVID-19 pandemic and its impacts, as necessary. Events and changes in circumstances arising after September 30, 2020, including those resulting from the impacts of COVID-19, will be reflected in management’s estimates for future periods.

This Management’s Discussion and Analysis (“MD&A”) of Financial Condition and Results of Operations should be read in conjunction with the unaudited condensed consolidated financial statements and the notes thereto included in this Quarterly Report on Form 10-Q and the audited financial statements and the notes thereto, as well as MD&A, included in the ~~2016~~2019 Annual Report to Shareholders, which is incorporated by reference into the ~~2016~~2019 Form10-K.

Executive Summary

The items discussed in this Executive Summary are intended to provide an overview of the results of the Company’s and Southwest’s operations. As needed, certain items are covered in greater detail in later sections of ~~management’s discussion and analysis.~~MD&A. As reflected in the table below, the natural gas operations segment accounted for an ~~average~~average of ~~81%~~73% of~~twelve-month-to-date~~ twelve-month-to-date consolidated net income over the past two years. As such, ~~management’s discussion and analysis~~MD&A is primarily focused on that segment. Natural gas sales are seasonal, peaking during the winter months; therefore, results of operations for interim periods are not necessarily indicative of results for a full year.

Improvements from natural gas operations to consolidated net income of $4 million occurred between the third quarters of 2020 and 2019. The improvement was primarily due to lower Operations and maintenance expense and an increase in Other income, offset by increases in Depreciation and amortization and Net interest deductions.

Operating margin ~~increased $6~~was slightly below the same quarter in the previous year. Customer growth provided approximately $2.6 million ~~between quarters. Rate relief in Arizona (effective April 2017) and California provided $4 million in operating~~of incremental margin ~~(see~~~~Rates and Regulatory Proceedings~~~~). Approximately $2 million in increased operating margin was attributable to customer growth, as 32,000 net new customers were added~~from 37,000 first-time meter sets during the last twelve ~~months.~~

months, while rate relief added $400,000 of margin. Offsetting these increases were other items, including impacts from a temporary moratorium on late fees and lower connection/re-connection charges during the COVID-19 pandemic. A reduction in amounts associated with regulatory account balances also impacted operating margin; however, effects of program recoveries are primarily offset in amortization expense (below).

Operations and maintenance expense ~~was relatively flat~~ decreased $7.9 million between quarters primarily due to the impacts of COVID-19 on training and travel costs and reductions in other service and maintenance costs. Additionally, lower legal claims-related costs contributed to the decrease between quarters. ~~Decreases~~Overall, operations and maintenance expenses are expected to increase in ~~employee-related benefit costs more than offset increases in other general costs.~~

the fourth quarter of 2020.

Depreciation and amortization expense ~~decreased $10~~increased $3.6 million, or 7%, between quarters, primarily ~~due~~due to ~~reduced depreciation rates in Arizona,~~ a ~~result of the recent Arizona general rate case decision. Partially offsetting the decline was increased depreciation associated with a $317~~$678 million, or 5%9%, increase in average gas plant in service ~~for the current quarter as~~ compared to the corresponding quarter a ~~year ago.~~year ago, offset by a decrease of $1.1 million associated with regulatory program balances. The increase in gas plant was attributable to pipeline capacity reinforcement ~~work,~~work, franchise requirements, scheduled ~~and accelerated~~ pipe replacement activities, and new infrastructure.

~~Taxes other than income taxes increased $1.6~~

Other income improved $3.1 million between quarters primarily due to higher property taxes associated with net plant additions and increased property taxes in Arizona, including the impact of a property tax tracking mechanism enacted as part of the recently settled Arizona general rate case.

~~Other income increased $560,000~~ between quarters primarily due to an increase in the equity portion of the allowance for funds used during construction (“AFUDC”) associated with higher construction expenditures. The equity portion of AFUDC represents the cost of equity funds used to finance utility construction. The equity AFUDC improvement was partially offset by a decline between quarters in income from ~~company-owned life insurance (“COLI”)~~COLI policies. The current quarter reflects ~~$2.1~~$4.5 million ~~of income associated with COLI policy cash surrender value increases, while the prior-year quarter reflected $2.3 million of COLI-related income. COLI amounts~~ in ~~each quarter were greater than expected.~~

Net interest deductions increased $1.1 million between quarters, primarily due to the September 2016 issuance of $300 million of senior notes, partially offset by reductions associated with the redemption of debt ($24.9 million of 4.75% IDRBs in September 2016) and lower interest expense associated with PGA balances as compared to the prior-year quarter.

~~The contribution to consolidated net~~ income from natural gas operations increased $14.9 million between the first nine months of 2017 and 2016. The improvement was primarily due to higher operating margin and lower depreciation expense, partially offset by an increase in operations and maintenance expenses.

~~Operating margin increased $17 million between the comparative nine-month periods. Rate relief in the Arizona and California jurisdictions provided $10 million in operating margin (see~~~~Rates and Regulatory Proceedings~~~~). The remaining $7 million increase was attributable to customer growth.~~

Operations and maintenance expense increased $11.4 million, or 4%, between periods due primarily to higher general cost increases. Approximately $5 million of the incremental costs recognized were associated with the amount and timing of employee incentive plan grants (including accelerated recognition for retirement eligible employees).

Depreciation and amortization expense decreased $20.8 million between periods primarily due to reduced depreciation rates in Arizona, a result of the recent Arizona general rate case decision. The depreciation decrease also included a decline of approximately $3.7 million in amortization related to the recovery of regulatory assets. Partially offsetting these declines was depreciation associated with a $325 million, or 5%, increase in average gas plant in service for the current period as compared to the prior period. The increase in gas plant was attributable to pipeline capacity reinforcement work, franchise requirements, scheduled and accelerated pipe replacement activities, and new infrastructure.

Taxes other than income taxes increased $3.8 million between periods primarily due to higher property taxes associated with net plant additions and increased property taxes in Arizona, including the impact of the Arizona property tax tracking mechanism.

~~Other income, which principally includes returns on COLI policies andnon-utility~~ ~~expenses, increased $2 million between periods.

COLI amounts in each period were greater than expected.~~

Net interest deductions increased $2.5 million between periods, primarily due to the September 2016 issuance of $300 million of senior notes, partially offset by reductions associated with debt redemptions ($100 million of 4.85% IDRBs in July 2016 and $24.9 million of 4.75% IDRBs in September 2016) and lower interest expense associated with PGA balances as compared to the prior-year period.

Contribution to consolidated net income
   $ 134,323    $ 119,836

Contribution to consolidated net income from natural gas operations increased by $14.5 million between the twelve-month periods of 2017 and 2016. The improvement was primarily due to higher operating margin and lower depreciation expense, partially offset by an increase in operations and maintenance expenses and interest expense.

Operating margin increased $26 million between periods including a combined $13 million of rate relief in the Arizona and California jurisdictions, as well as Paiute Pipeline Company. Customer growth provided $9 million in operating margin, while operating margin associated with recoveries of regulatory assets, infrastructure replacement mechanisms, customers outside the decoupling mechanisms, and other miscellaneous revenues improved $4 million.

Operations and maintenance expense increased $12.9 million, or 3%, between periods primarily due to general cost increases, partially offset by lower pension expense. Approximately $5.6 million of the incremental costs recognized were associated with the amount and timing of employee incentive plan grants (including accelerated recognition for retirement-eligible employees). Pipeline integrity management and damage prevention programs collectively increased $500,000.

Depreciation and amortization expense decreased $15.9 million between periods primarily due to reduced depreciation rates in Arizona, a result of the recent Arizona general rate case decision. Partially offsetting the decline was depreciation associated with a $335 million, or 6%, increase in average gas plant in service for the current period as compared to the prior period. The increase in gas plant was attributable to pipeline capacity reinforcement work, franchise requirements, scheduled and accelerated pipe replacement activities, and new infrastructure.

Taxes other than income taxes increased $4.4 million between periods primarily due to higher property taxes associated primarily with net plant additions and increased property taxes in Arizona, including the impact of a property tax regulatory tracking mechanism resulting from the recent Arizona general rate case.

~~Other income increased $693,000 between the twelve-month periods of 2017 and 2016. The current period reflects an $8.8 million increase~~ in COLI policy cash surrender values, while the prior-year ~~period reflected $7.5 million~~quarter reflected $200,000 in related income. These values are significantly impacted by fluctuations in the values of ~~combined COLI-related income~~equity securities associated with the cash surrender values, and ~~recognized death~~values in both quarters were impacted consistent with the broader securities markets. Offsetting these impacts were higher non-service-related costs associated with employee pension and other postretirement benefits. ~~COLI amounts in each period were greater than expected.~~

Net interest deductions increased ~~$4.3~~$2.5 million in the third quarter of 2020, as compared to the prior-year quarter, primarily due to the issuance of $450 million of Senior Notes in June 2020, offset by lower borrowings under Southwest’s credit facility. Refer to Note 5 - Debt in Notes to Financial Statements in this Form 10-Q for the use of proceeds, including the ultimate redemption of maturing debt in September 2020. Increased carrying costs on PGA balances, primarily in Nevada, also contributed to the increase.

The decline was primarily due to a decrease in Other income and increases in Depreciation and amortization and Net interest deductions, partially offset by an increase in Operating margin and lower Operations and maintenance expense.

Operating margin increased $15 million, including $11 million attributable to customer growth. Rate relief, primarily in California, contributed an additional $2 million in operating margin. The prior-year period included an approximate $5 million reduction in margin resulting from a one-time adjustment by the Arizona Corporation Commission to reflect the impacts of U.S. tax reform on the Arizona decoupling mechanism. Offsetting these impacts are lower late fees and connect/re-connect charges during the current moratorium discussed earlier. Residual impacts include those related to regulatory mechanisms, including recovery/return of regulatory program balances (primarily offset in amortization expense), in addition to margin from customers outside the decoupling mechanisms.

Operations and maintenance expense decreased $16 million, or 5%, between periods. Reductions in training and travel costs due to the COVID-19 environment, as well as lower legal claims-related costs, and decreases in other service and maintenance costs contributed to the decline between periods.

Depreciation and amortization expense increased $15 million, or 9%, between periods primarily due to a $682 million, or 9%, increase in average gas plant in service between periods. The increase in gas plant was attributable to pipeline capacity reinforcement work, franchise requirements, scheduled pipe replacement activities, and new infrastructure. Amortization associated with regulatory account balances, as noted above, also resulted in increases in expense in the current period.

Other income decreased $17.1 million overall between periods. The current period reflects $1 million of COLI-related income, while the prior-year period reflected $11.2 million of COLI-related income. The non-service cost components of employee pension and other postretirement benefits were $3.7 million higher between periods. Lower interest income on regulatory account balances also contributed to the decrease between periods.

Net interest deductions increased $5.1 million between periods, primarily due to interest associated with the ~~September 2016~~ issuance of $300 million of ~~senior notes. The increase was~~Senior Notes in May 2019 and $450 million of Senior Notes in June 2020, partially offset by ~~reductions associated with the redemption of debt ($100 million of 4.85% IDRBs in July 2016 and $24.9 million of 4.75% IDRBs in September 2016)~~reduced interest rates and lower ~~interest expense associated with PGA~~outstanding balances ~~as compared to the prior-year period.~~

Contribution to consolidated net income from ~~construction services~~natural gas operations increased $10 million between the twelve-month periods ended September 2020 and 2019. The increase was primarily due to an increase in Operating margin and lower Operations and maintenance expense and Income tax expense, partially offset by higher Depreciation and amortization expense, Net interest deductions, and lower Other income.

Operating margin increased $32 million between periods. Customer growth provided $14 million, and combined rate relief, primarily in Nevada and California, provided $5 million of incremental operating margin. The prior-year period included an approximate $5 million reduction in margin resulting from a one-time adjustment to reflect the impacts of U.S. tax reform on the Arizona decoupling mechanism. The remaining net increase primarily resulted from regulatory mechanisms, notably an increase in regulatory asset recoveries (see discussion of amortization expense below).

Operations and maintenance expense decreased $6.2 million (or 1%) between periods primarily due to lower training and travel costs due to the current COVID-19 environment, as well as decreases in other service and maintenance costs, offset by incremental expenditures for pipeline damage prevention programs and increases in employee pension and other postretirement benefits.

Depreciation and amortization expense increased $24.6 million, or 12%, between periods primarily due to a $670 million, or 9%, increase in average gas plant in service since the corresponding period in the prior year. Amounts associated with regulatory program balances increased approximately $8 million between periods.

Other income decreased $2.4 million between the twelve-month periods of 2020 and 2019 primarily due to lower interest on regulatory account balances, a decrease in amounts associated with the allowance for equity funds applied to projects during construction, and higher non-service cost components of employee pension and other postretirement benefits. Offsetting these impacts was an increase between periods in COLI policy cash surrender values. The current twelve-month period reflects a $7.2 million increase in COLI cash surrender values, while the prior-year period reflected a $2 million increase.

Net interest deductions increased $8.1 million between periods primarily due to interest associated with the issuance of $300 million of Senior Notes in May 2019 and $450 million of Senior Notes in June 2020, offset by a reduction in outstanding borrowings under the credit facility.

The reduction in income taxes between periods reflects lower state income taxes (due to apportionment changes) and an additional $1.2 million in amortization of excess accumulated deferred income taxes following U.S. tax reform, which reduces tax expense.

Utility infrastructure services revenues increased $65.1 million in the third quarter ~~decreased by $542,000~~of 2020 when compared to the prior-year quarter. ~~The decrease is~~Approximately $48.7 million in revenue was recognized during the third quarter from emergency restoration services related to hurricane damage in the Gulf Coast and eastern regions of the U.S. Storm restoration revenues during the same quarter in 2019 totaled $6.3 million. Restoration revenues are contracted under time-and-material rates and generally involve a higher number of hours worked per day given the emergency response nature of the work performed. Centuri’s revenues derived from these services vary from period to period due to the unpredictable nature of weather-related events, and can also vary greatly depending on the geographic area, customer mix, and rate of compensation under the contract. Higher volumes of gas and electric infrastructure work under blanket and bid contracts were also realized during the third quarter of 2020.

Utility infrastructure services expenses increased $51.4 million in the third quarter of 2020 when compared to the prior-year quarter, due primarily to increased costs associated with storm restoration services, as well as costs to complete additional gas and electric infrastructure work. Existing crews are diverted from other work to perform storm restoration work, which typically generates a higher profit margin than other core infrastructure services due to improved operating efficiencies related to equipment utilization and absorption of fixed costs. Such profit margins can vary greatly depending on the geographic area, customer mix, and contract terms as noted above. Also included in total Utility infrastructure services expenses were general and administrative costs, which increased $6.7 million in the current quarter when compared to the corresponding quarter in 2019 due to higher ~~construction~~payroll and operating costs ~~relative to increased revenues, resulting from apre-tax~~ ~~loss on a project described below, partially offset by a decline in depreciation and amortization.~~

~~Revenues increased $40.3 million, or 12%, between quarters primarily due to an increase in pipe replacement work~~associated with ~~existing customers. A significant portion~~continued growth of the ~~increase relates to bid jobs that are expected to be substantially complete by year end.~~

~~Construction expenses increased $42 million, or 14%, between quarters due to additional pipe replacement work. Results were negatively impacted by~~business and higher construction costs for a water pipe replacement project, for which Centuri has requested increased cost recovery. No additional work orders will be accepted on the project pending resolution of Centuri’s request. Gains on sale of equipment (reflected as an offset to construction expenses) were approximately $25,000 and $1.4 million for the third quarters of 2017 and 2016, respectively.

Depreciation and amortization ~~decreased $1.1~~expense increased $1.2 million between quarters ~~primarily due~~attributable to ~~a $2 million reduction associated with the extension of the estimated useful lives of certain depreciable equipment during the past 12 months, partially offset by an increase in depreciation for~~ additional equipment purchased to support the growing volume of work being performed.

Net interest deductions decreased $1.8 million between periods due primarily to lower rates associated with outstanding borrowings under Centuri’s $590 million secured revolving credit and term loan facility.

Utility infrastructure services ~~for~~revenues increased $126.3 million during the first nine months of ~~2017 declined by $3.6 million~~2020 when compared to the ~~prior-year period. The decrease is~~same period in the prior year, primarily due to a higher ~~construction~~ volume of gas and electric infrastructure work under blanket and bid contracts. For the first nine months of 2020, $56 million of revenues were from emergency restoration services related to hurricane and tornado damage in the Gulf Coast and eastern regions of the U.S. as compared to $13.2 million during the same period in 2019. As noted earlier, Centuri’s revenues derived from storm restoration services vary from period to period due to the unpredictable nature of weather-related events, and the contract terms for the emergency response, as discussed earlier. Also, during the first nine months of 2020, Centuri earned incremental revenues of approximately $25 million related to a new bid job with an existing gas infrastructure customer in Canada that commenced during the current year. Centuri achieved these increases despite a temporary shut-down of certain crews, primarily in the second quarter of 2020, in response to local government requirements to postpone non-essential business services and precautions to ensure employee safety during the COVID-19 outbreak.

Utility infrastructure services expenses increased $98.3 million during the first nine months of 2020 when compared to the same period in the prior year, due primarily to costs ~~relative~~ to complete additional gas and electric infrastructure work as well as increased costs associated with storm restoration revenues, partially offset by increased productivity and efficiencies on electrical infrastructure projects and lower fuel costs as a ~~decline~~percentage of revenues. Storm restoration work typically generates a higher profit margin than core infrastructure services due to improved operating efficiencies related to equipment utilization and absorption of fixed costs. Offsetting these favorable impacts were certain increased costs and workforce inefficiencies, primarily in ~~depreciation~~the second quarter of 2020, associated with the impact of the COVID-19 pandemic. During the first nine months of 2020, Centuri received $4.1 million in wage subsidies from the Canadian government associated with COVID-19. These funds were recorded as a reduction to wage expense. Also included in total Utility infrastructure services expenses were general and ~~amortization.~~

~~Revenues~~administrative costs, which increased ~~$34.5~~$15.8 million ~~or 4%,~~ in the first nine months of ~~2017~~2020 when compared to the ~~prior-year~~corresponding period ~~primarily~~during 2019 due to ~~increased pipe replacement work. Partially offsetting increases in revenues was a temporary work stoppage by a significant customer that began in the first quarter of 2017~~higher payroll and operating costs associated with continued ~~through part~~growth of the ~~second quarter of 2017 resulting in a $26.3 million reduction in revenues, compared to the prior-year period,~~business and ~~a $3.7 millionpre-tax~~ loss in the current nine-month period. The temporary work stoppage was initiated due to state-mandated requalification of employees of all contractors working within the jurisdictional boundary of one state. Operations resumed gradually following the requalification of Centuri’s employees during the second quarter of 2017. Additionally, inclement weather in several operating areas negatively impacted revenues and reduced productivity in the first quarter of 2017.

Construction expenses increased $48.7 million, or 6%, between periods. The increase in construction expenses is disproportionate to revenues noted above due in part to logistics surrounding the timing and length of the temporary work stoppage with the significant customer and to higher ~~labor costs incurred to complete work during inclement weather conditions in the first quarter. In addition, results were negatively impacted by higher construction andstart-up~~ costs related to the water pipe replacement project, for which Centuri is pursuing cost recovery. Gains on sale of equipment (reflected as an offset to construction expenses) were approximately $1.5 million and $4.1 million for the first nine months of 2017 and 2016, respectively.

Depreciation and amortization ~~decreased $7.9~~expense increased approximately $7 million between periods, ~~primarily due~~attributable to an $8.2 million reduction in depreciation associated with the extension of the estimated useful lives of certain depreciable equipment during the past 12 months, partially offset by an increase in depreciation for additional equipment purchased to support the growing volume of work being performed.

Net interest deductions decreased $3.4 million during the first nine months of 2020 due primarily to lower rates associated with outstanding borrowings under Centuri’s $590 million secured revolving credit and term loan facility.

SOUTHWEST GAS CORPORATION						September 30, ~~2017~~2020

Rates and Regulatory Proceedings

Southwest is subject to the regulation of the Arizona Corporation Commission (the “ACC”), the Public Utilities Commission of Nevada (the “PUCN”), the California Public Utilities Commission (the “CPUC”), and the Federal Energy Regulatory Commission (the “FERC”).

General Rate Relief and Rate Design

Rates charged to customers vary according to customer class and rate jurisdiction and are set by the individual state and federal regulatory commissions that govern Southwest’s service territories. Southwest makes periodic filings for rate adjustments as the cost of providing service (including the cost of natural gas purchased) changes, and as additional investments in new or replacement pipeline and related facilities are made. Rates are intended to provide for recovery of all commission-approved costs and a reasonable return on investment. The mix of fixed and variable components in rates assigned to various customer classes (rate design) can significantly impact the operating margin actually realized by Southwest. Management has worked with its regulatory commissions in designing rate structures that strive to provide affordable and reliable service to its customers while mitigating volatility in prices to customers and stabilizing returns to investors. Such rate structures were in place in all of Southwest’s operating areas during all periods for which results of natural gas operations are disclosed above.

Arizona Jurisdiction

Arizona General Rate Case. On May 1, 2019, Southwest filed a general rate case application ~~with~~requesting to increase revenue by approximately $57 million to update the cost of service to reflect recent U.S. tax reform changes, including the return of excess deferred income taxes to customers, and to reflect capital investments of approximately $670 million, including certain post-test year additions, including the southern Arizona ~~Corporation Commission~~LNG facility discussed below. The application also included a proposed 10.3% return on equity (“~~ACC”~~ROE”) relative to a capital structure of 51.1% equity. At the time of the original filing, the Company estimated the return of approximately $20.6 million of excess accumulated deferred income taxes (“EADIT”), which was updated through an amended filing in ~~May 2016 requesting~~October 2019 to $5.7 million in actual amortization of EADIT, known after the Company’s 2018 federal income tax return was filed in 2019. The actual amount, determined based on a prescribed methodology, is the amount that may be returned to customers. The difference of $14.9 million would result in an increase in ~~authorized~~revenue and income tax expense, thereby having no impact on earnings overall. In association with the amendment, Southwest also included additional post-test year plant in the amount of $124.5 million associated with its COYL and VSP programs, discussed further below. The amendment overall increased the deficiency by $36 million, to $93 million. Through the discovery and testimony exchanges, Southwest updated certain aspects of its cost of service, including a revised proposed ROE of 10.15%, resulting in an updated proposed increase of $90.6 million. The updated request includes the retention of a fully decoupled rate design, other previously approved regulatory mechanisms, and a new infrastructure tracking mechanism for specific plastic pipe. It also includes a proposal for a renewable natural gas program that authorizes Southwest to purchase renewable natural gas for its customers and to recover the cost as part of its purchased gas adjustment mechanism. The original hearing date was postponed due to the COVID-19 pandemic and was convened in June and July. Prior to the start of the hearing, Southwest entered into a stipulation with the parties to the case on a number of issues. As part of the stipulation, the parties agreed to continue the COYL program; to establish a Tax Expense Adjustor Mechanism to track annual ~~operating revenues~~changes in the amortization of EADIT, as well as any future changes in the federal tax rate; to incorporate various tariff proposals; and to include a resolution for a 10-year amortization period for EADIT associated with deemed “unprotected” plant. EADIT associated with “protected” plant relates to timing differences from using accelerated depreciation for tax purposes and another method for book purposes, and “unprotected” amounts relate to all other timing differences. The legal briefing was completed in mid-September, with a Commission decision expected during the fourth quarter.

Delivery Charge Adjustment. The annual Delivery Charge Adjustment (“DCA”) is filed each April, which along with other reporting requirements, contemplates a rate to recover the over- or under-collected margin tracker amounts based on the balance at the end of the preceding calendar year. In the process to address the 2019 activity, in April 2020, Southwest filed a request to adjust the existing rate to consider the 14-month period of January 1, 2019 through February 29, 2020, proposing a rate of $0.00655 per therm based on an ending balance of approximately $32 million, or 4.2%, to reflect existing levels of expense and requested returns, in addition to reflecting capital investments made by Southwest since June 2010. The application requested an overall$3.5 million. Although Commission Staff concurred with Southwest’s proposed rate, of return of 7.82% on an original cost rate base of $1.336 billion, a 10.25% return on common equity, and a capital structure utilizing 52% common equity. The filing included a depreciation study that supported a proposalthe ACC ultimately elected to reduce ~~currently effective depreciation expense by approximately $42 million, which was considered~~the rate to zero in an effort to provide some measure of customer relief in light of current issues related to the ~~overall requested amount. This expense reduction coupled with~~COVID-19 pandemic, and at the ~~requested revenue increase, resulted in a net annual operating income increase request~~time of ~~$74 million. A settlement was reached among several parties in December 2016 and a formal draft settlement was filed in January 2017. Hearings were held in February 2017,~~both the April filing and the ACC ~~approved~~decision, the ~~settlement agreement~~balance was a liability (in an over-recovered status). Any over-or under-collection will be addressed in Southwest’s next annual filing.

Tax Reform. In February 2018, the ACC directed all Arizona utilities to address tax savings from the enactment of U.S. tax reform beginning January 1, 2018, through one of various means. In April 2017. The settlement provides for an overall operating revenue increase of $16 million and the capital structure and cost of capital as proposed by Southwest, with the exception of the return on common equity, which was set at 9.50%. Depreciation expense is expected to be reduced by $44.7 million, for a combined net annual operating income increase of $60.7 million. Other key elements of the settlement include approval of the continuation and expansion of the current Customer-Owned Yard Line (“COYL”) program (adding the ability to seek out COYLs through a targeted approach and mobilization of work crews for replacement), implementation of a vintage steel pipe replacement program, and a continuation of the current decoupled rate design, excluding a winter-period adjustment to rates, making the mechanism fundamentally similar to that which exists in Nevada. The settlement also included a property tax tracking mechanism to defer changes in property tax expense for recovery or return in the next general rate case. New rates were effective April 2017. The settlement also includes a three-year rate case moratorium prohibiting a new application to adjust base rates from being filed prior to May 2019.

In January 2014,~~2018, Southwest filed an application with the ACC, ~~seeking~~requesting approval for a tax refund process or, in the alternative, the authority to file a general rate case to reflect the impacts of tax reform. Ultimately, Southwest was instructed to refund customers $20 million annually, as compared to rate levels

established in the previously concluded general rate case, until cost-of-service rates are updated in association with the pending general rate case. The current method to return this amount (in advance of the conclusion of the current general rate proceeding) is through a per-therm surcredit. Southwest has been tracking monthly differences between amounts expected to be returned and amounts actually returned to customers during 2018 and 2019, and continuing in 2020, which has resulted in an asset balance of $2 million as of September 30, 2020.

Liquefied Natural Gas (“LNG”) Facility. In 2014, Southwest sought ACC preapproval to construct, operate, and maintain a 233,000 dekatherm LNG facility in southern Arizona. This facility is intended to enhance service reliability and flexibility inrelated to natural gas deliveries in the southern Arizona area by providing a local storage option, to be operated by Southwest, and connected directly to its distribution system. ~~In December 2014,~~ Southwest ~~received an order from the ACC grantingpre-approval~~ ~~of Southwest’s application to construct the LNG facility~~was ultimately granted approval for construction and ~~the~~ deferral of costs upnot to ~~$50~~exceed $80 million. ~~Following the December 2014 preapproval, Southwest purchased the site for the~~The facility and completed detailed engineering design specifications for the purpose of soliciting bids for the engineering, procurement and construction (“EPC”) of the facility.

Customer-Owned Yard Line (“COYL”) Program. Southwest received approval, in connection with ~~an earlier~~its 2010 Arizona general rate case, to implement a program to conduct leak surveys, and if leaks were present, to replace and relocate service lines and meters for Arizona customers whose meters were set off from the customer’s home, ~~which is not~~representing a ~~traditional~~non-traditional configuration. ~~Customers with this configuration were previously responsible for the cost of maintaining these lines and were subject to the immediate cessation of natural gas service iflow-pressure~~ ~~leaks occurred. Effective June 2013,~~In 2014, the ACC ~~authorized~~approved a ~~surcharge to recover~~“Phase II” of the ~~costs~~COYL program, which included the replacement of ~~depreciation andpre-tax~~ ~~return on the costs incurred to replace and relocate service lines and meters.~~non-leaking COYLs. The surcharge is ~~revised annually~~designed to collect the annual revenue requirement as the program progresses. In ~~2014, Southwest received approval to add a “Phase II” component to~~ the ~~COYL program to include the replacement ofnon-leaking~~ ~~COYLs. In the most recent annual COYL~~ filing made in February ~~2017,~~2019, Southwest requested to ~~establish an annual~~increase its surcharge to ~~collect $1.8 million related to the~~recover a revenue requirement of $6.7 million (an increase of $3.2 million) associated with ~~$12.1~~$26.6 million in capital projects completed ~~under both Phase I and Phase II during 2016.

The ACC ultimately issued an Order in October 2019 authorizing Southwest to retain the existing annual surcharge of $3.5 million, indicating it would review the program as part of the pending general rate case. As discussed above, the parties to the pending rate case stipulated to continue the COYL program. Southwest also proposed to have the ACC ~~issued~~review an estimated $21.1 million of 2019 COYL capital projects, and if authorized, to also render a decision ~~approving~~regarding cost recovery as part of the ~~surcharge application.

Vintage Steel Pipe ~~Program~~.(“VSP”) Program. Southwest received approval, in connection with its ~~most recent~~2016 Arizona general rate case, to implement a ~~vintage steel pipe (“VSP”)~~VSP replacement program. Southwest currently has ~~approximately 6,000 miles~~a substantial amount ofpre-1970s vintage steel pipe in Arizona. As part of the program, Southwest proposed to start replacing the pipe on an accelerated basis and to recover the costs through an annual surcharge ~~filing that will be made in February of each year. The~~filing. A surcharge isrelated thereto has been customarily designed to be revised annually as the program ~~progresses.~~progresses to collect the annual revenue requirement associated with the related capital expenditures. In the most recent VSP filing, in February 2019, Southwest requested to increase its surcharge revenue by $9.5 million (to $11.9 million) associated with the replacement of approximately $100 million in 2018 VSP capital projects. The ACC issued an Order in October 2019 authorizing Southwest to retain the current annual surcharge of $2.4 million and indicated it would review the program as part of the pending rate general case. Southwest also proposed to have the ACC review an estimated $103.4 million of 2019 VSP capital projects, and if authorized, to also render a decision regarding cost recovery as part of the pending rate case. As part of their filed testimony in the current case, the ACC Staff and the consumer advocate recommended recovery of this plant as part of Southwest’s filed post-test year plan adjustment, with inclusion of related amounts in base rates. The further continuation of the VSP is pending a decision in the current general rate proceeding.

Customer Data Modernization Initiative. Southwest has embarked on an initiative to replace its customer service system and gas transaction systems, each of which is utilized to support all Southwest service territories. Combined, these undertakings are referred to as the Customer Data Modernization Initiative (the “CDMI”). In March 2019, Southwest filed an application with the ACC seeking an accounting order which, if approved, would authorize Southwest to track and defer all costs associated with the CDMI to mitigate adverse financial implications associated with this multi-year initiative. The total cost for the CDMI is estimated at $174 million, approximately $96 million of which would be allocable to the Arizona rate jurisdiction. The initiative is currently expected to be completed in the first half of 2021. A ~~Plan~~hearing in this matter was held in June 2020. The legal briefing was completed in mid-September, with a Commission decision expected in the fourth quarter.

California Jurisdiction

California General Rate Case. Southwest’s existing rates became effective June 2014, and included a Post-Test Year (“PTY”) Ratemaking Mechanism, which allowed for attrition increases of ~~Administration (“POA”)~~2.75% annually for 2015 through 2018, after which time new rates from a subsequent rate case cycle would have been expected to be in effect. In December 2016, Southwest filed to modify

SOUTHWEST GAS CORPORATION						September 30, 2020

the earlier (2014) general rate case decision to extend the rate case cycle by two years, and received CPUC approval in June 2017, including extension of the annual 2.75% PTY attrition adjustments for 2019 and 2020.

On August 30, 2019, Southwest filed the previously deferred general rate case, based on a test year of 2021, seeking authority to increase rates in its California rate jurisdictions. The proposed combined revenue increase of $12.8 million was net of a $10.9 million revenue reduction associated with changes from U.S. tax reform, which included the amortization of $9.8 million (approximately $2 million annually over five years) associated with the difference in authorized income tax expense and actual incurred income tax expense for years 2019 and 2020, which when returned will impact cash flows, but would not be expected to have an impact on earnings. Southwest has been tracking those amounts, as directed, and reserving them for return to customers. The overall revenue request also included $1.6 million of EADIT proposed to be returned to customers each year until the amount is reset as part of a future rate case. Southwest’s proposal included an ROE of 10.5%, ~~which~~relative to a 53% equity ratio; continuation of annual post-test year margin adjustments of 2.75%; implementation of various safety-related programs, including a targeted pipe replacement program and a meter protection program (with a combination of measures, such as snow sheds, excess flow valves, upgraded meter set piping and upgraded Encoder Receiver Transmitter protocol); as well as an expansion of the school COYL replacement program. Ahead of hearings scheduled to begin in late June, Southwest reached an agreement in principle with the Public Advocate’s Office for settlement of the pending general rate case.

The agreement in principle includes a $6.4 million total combined revenue increase with a 10% ROE, relative to a 52% equity ratio. Approximately $4 million of the original proposed increase of $12.8 million is associated with a North Lake Tahoe project that will not be completed by the beginning of 2021; consequently, the parties agreed to remove it from the base rate increase and instead Southwest will recover the cost of the project through a surcharge as described below. The agreement also maintains Southwest’s existing 2.75% annual attrition adjustments, the continuation of the pension balancing account, and approves the proposed increase in the residential basic service charge from the existing $5.00 to $5.75 per month. The parties also agreed to a cumulative total of $119 million over the five-year rate cycle to implement proposed risk-informed decision making proposals, consisting of the school COYL replacement, meter protection, and pipe replacement programs. Southwest is also authorized to implement a surcharge annually to recover the cost of these programs. The agreement in principle was filed in ~~March of 2017~~early August 2020, and ~~was~~if approved, new rates would be expected to become effective in conjunction with the general rate case, outlined the VSP program requirements and established the timeline for future project plans and surcharge requests. Southwest is currently targeting the replacement of nearly 40 miles of VSP during 2017 totaling approximately $27 million and replacement projects during 2018 of approximately $100 million.

~~California Jurisdiction~~

January 2021.

Attrition Filing. In November ~~2016,~~2019, Southwest made its latest annual ~~post-test year (“PTY”)~~PTY attrition filing, ~~with the California Public Utilities Commission (“CPUC”),~~ requesting annual revenue increases of ~~$2.1~~$2.06 million in southern California, ~~$513,000~~$556,000 in northern California, and ~~$256,000~~$278,000 for South Lake Tahoe. This filing was approved in December ~~2016~~2019 and rates were made effective in January ~~2017.~~2020. At the same time, rates were also updated to recover the regulatory asset associated with the revenue decoupling mechanism, or margin tracker.

Greenhouse Gas (“GHG”) Compliance. California Assembly Bill Number 32 and regulations promulgated by the California Air Resources Board, require Southwest, as a covered entity, to comply with applicable requirements associated with California GHG emissions reporting and the California Cap and Trade Program. The CPUC issued a decision in 2018 adopting an allocation methodology to distribute the net revenues or costs. Southwest began amortizing its then existing net cost balance over a 12-month period with recovery rates effective July 2018 for all applicable rate schedules. In addition, for years 2019-2020, the decision adopted an allocation methodology to distribute the revenue proceeds through a California Climate Credit to active residential customers in April of each year, following initial required credits in October 2018. Amounts distributed in April 2019 and 2020 were comparable. GHG compliance costs recovered through rates have no impact on earnings.

Renewable Natural Gas. In February 2019, Southwest filed an application that, among other things, sought to formally allow the inclusion of renewable natural gas (or biomethane) as a potential component of Southwest’s gas supply portfolio through the Biomethane Gas Program (“BGP”). This proposal is designed to further the goals of the California Global Warming Solutions Act of 2006, the California Low Carbon Fuel Standard, Senate Bills 1383 and 1440, as well as current or future legislative or regulatory efforts to reduce greenhouse gas emissions. Implementation of the BGP addresses cost recovery as part of Southwest’s existing Gas Cost Incentive Mechanism related to the purchase or sale of biomethane. The CPUC issued a final decision approving the proposal in March 2020.

Customer Data Modernization Initiative. On April 26, 2019, Southwest filed an application with the CPUC seeking authority to establish a two-way, interest bearing balancing account to record costs associated with the CDMI to mitigate adverse financial implications associated with this multi-year project. Approximately $19 million of the estimated $174 million total for the CDMI would be allocable to the California rate jurisdiction. Southwest filed a separate request to establish a memorandum account while the CPUC considered its application request to establish the two-way balancing account. Effective October 2019, the CPUC granted Southwest’s memorandum account request, which would allow Southwest to track costs, including operations and maintenance costs and capital-related costs, such as depreciation, taxes, and return associated with California’s portion of the CDMI. The balance tracked in the memorandum account would be transferred to the two-way balancing account, if approved. In January 2020, Southwest and the Public Advocates Office reached a settlement agreement to adopt Southwest’s


			44

Application for Authority to Implement the CDMI. The CPUC issued a final decision approving the settlement agreement as filed in July 2020. A rate to begin recovering the balance accumulated through June 30 was established and made effective September 1, 2020. This rate will be updated annually thereafter each January, beginning January 2021.
Emergency Relief Program Related to COVID-19. On March 25, 2020, Southwest filed an Advice Letter to establish a memorandum account to track costs related to customer protections under Emergency Relief regulations implemented in 2019 in the event of a state or federal declared emergency or disaster. The CPUC passed an emergency resolution on April 16, 2020 authorizing and directing utilities to implement customer protections and to establish memorandum accounts to track the financial impacts of complying with the resolution. On May 1, 2020, Southwest filed an Advice Letter to establish a COVID-19 Pandemic Protections Memorandum Account (“CPPMA”) to record all incremental costs and lost revenues incurred by Southwest associated with its implementation of the COVID-19 customer protections as outlined in the CPUC resolution. The customer protections were retroactively applied to March 4, 2020, the date Governor Gavin Newsom declared a state of emergency related to COVID-19. The CPPMA is effective March 4, 2020 through April 16, 2021. These customer protections focus on flexible payment plan options, additional protections for income-qualified customers, as well as the suspension of disconnections for non-payment and the waiver of deposit and late fee requirements. Tracked amounts will be considered by the CPUC for future recovery.
Nevada Jurisdiction

Nevada General Rate ~~Case~~~~. In December 2016,~~ Case.Southwest filed a general rate case application with the PUCN in February 2020, which requested a statewide overall general rate increase of approximately $38.3 million. The request sought an ROE of 10% relative to ~~modify~~a proposed capital structure of 50% equity and continuation of the ~~most recent~~General Revenues Adjustment (“GRA”) mechanism (full revenue decoupling). The request also proposed the recovery of previously excluded costs attributable to several software applications. In June 2020, Southwest submitted its certification filing to update certain balances through May 31, 2020, which increased its overall proposed rate increase to $38.5 million. Commission Staff and the Bureau of Consumer Protection filed testimony in July, recommending an overall increase of approximately $21.6 million and approximately $20 million, respectively. A hearing in this matter was held in August 2020, with the Commission issuing its final order on September 25, 2020. The final order provides for an authorized combined revenue increase of approximately $23 million for northern and southern Nevada and continuation of the currently authorized 9.25% ROE with a capital structure of 49.26% equity and 50.74% debt. Southwest’s existing GRA was authorized to continue without modification. Full cost recovery of the unamortized balance of previously excluded software projects was authorized, along with the inclusion of all proposed Gas Infrastructure Replacement (“GIR”) and Mesquite Expansion projects in rate base, and full recovery of test year and certification operations and maintenance expenses associated with the CDMI project. Rates became effective in October 2020.

The previous general rate case decision, in December 2018, authorized an ROE of 9.25% relative to ~~extend the current~~Southwest’s proposed capital structure of 49.66% equity applicable to both southern and northern Nevada. Rates from this earlier proceeding originally became effective in January 2019. As part of that proceeding, management filed a request for reconsideration of several rate case ~~cycle by two years, including extension~~issues during the same month of effective rates; however, the PUCN ultimately granted no further rate relief. A modified final decision, following certain technical clarifications to calculations of the ~~annual PTY attrition adjustments through~~decision, resulted in a final revenue increase of $9.2 million in southern Nevada and a revenue decrease in northern Nevada of $2.1 million. The modified rates became effective in March 2019. Management decided to seek judicial review of the PUCN’s rate order, which was considered in January 2020. The District Court Judge deferred to the PUCN’s original findings. In March 2020, ~~from 2018. That latest rate case decision would have required~~ Southwest to file its next general rate application by September 2017. Expedited consideration was requested and in June 2017, the CPUC approved the request, thereby extending the rate case filing deadline. Southwest believes this extension is in the public interest as it provides rate stability to customers for two additional years consistentfiled an appeal with the ~~current reasonable rates approved~~Nevada Supreme Court, which remains active; the resolution will likely take 12-24 months.

General Revenues Adjustment. The continuation of the GRA was affirmed as part of ~~the last~~Southwest’s recently concluded general rate case, ~~and~~effective October 2020. Southwest makes Annual Rate Adjustment (“ARA”) filings to update rates to recover or return amounts associated with various regulatory mechanism, including the ~~current revenue requirement and rate of return are not in need of adjustment (with the continuation of the currently approved 2.75% PTY attrition adjustment for the two additional years).~~

Furthermore, a GIR rate application is generally filed each ~~year, Southwest files a Gas Infrastructure Replacement (“GIR”) Advance Application requesting authority to replace qualifying infrastructure and files separately as part of an annual GIR filing~~October to reset the GIR recovery surcharge rate related to previously approved and completed ~~projects. For~~ projects, ~~approved in 2015 and completed in 2016, the annualized revenue was approximately $4.5 million. In September 2016,~~with new rates typically becoming effective each January. On October 1, 2019, Southwest filed a rate application to ~~adjust~~reset the ~~GIR~~recovery surcharge to ~~recover the~~include cumulative deferrals through August 31, 2019. This surcharge rate became effective February 1, 2020 and is expected to result in a reduction in annual revenue ~~requirement~~of approximately $5.3 million in southern Nevada and no incremental revenue in northern Nevada. On September 30, 2020, Southwest filed its latest rate application to reset the recovery surcharge to include cumulative deferrals through August 31, 2020. The surcharge rate is expected to result in a reduction in annual revenue of approximately $11.8 million effective January 1, 2021.

Conservation and Energy Efficiency. The PUCN allows deferral (and later recovery) of approved conservation and energy efficiency costs, recovery rates for which are adjusted in association with ARA filings. In its June 2019 ARA filing, Southwest proposed annualized margin increases of $3.2 million and $880,000 in southern and northern Nevada, respectively. However, Southwest entered into a stipulation and agreement to modify these amounts ~~previously deferred. This filing~~to $6.2 million and $1.1 million in southern and northern Nevada, respectively, which reflected the recovery of a related but separate program balance to be rolled into customer rates with the same effective date. The modification was approved, ~~in December 2016~~ and ~~new~~ rates became effective January ~~2017.~~2020. In ~~June 2016,~~its May 2020 ARA filing, Southwest ~~filed an Advance Application~~proposed annualized margin decreases of $313,000 and $55,000 for ~~projects expected to be completed during 2017, proposing approximately $60 million of accelerated pipe replacement to include early vintage plastic, early vintage steel,~~southern and a COYL program. The COYL program, while not large in magnitude, represents the first of its kind in Nevada, modeled after the program in place for several years in Southwest’s Arizona jurisdiction. The PUCN issued an Order on the Advance Application in October 2016, approving approximately $57.3 million of replacement work with an annualized revenue requirement estimated at approximately $5.3 million. With regard to the proposed COYL program, approval was granted for the northern Nevada, ~~rate jurisdiction, but consideration for the southern Nevada rate jurisdiction was deferred until 2020, at which time certain early vintage plastic pipe programs are expected to be completed.~~respectively.

Expansion and Economic Development Legislation. In ~~September 2017, Southwest filed to adjust the GIR surcharge to recover the annual revenue requirement for amounts previously deferred. For projects approved in~~January 2016, ~~and completed by July of 2017~~


~~SOUTHWEST GAS HOLDINGS, INC.~~		~~Form 10-Q~~
~~SOUTHWEST GAS CORPORATION~~		~~September 30, 2017~~

~~, the deferred annualized revenue requirement is approximately $8.7 million. This filing is expected to be approved in December 2017 with rates becoming effective January 2018.~~

In May 2017, Southwest filed a GIR Advance Application with the PUCN for projects totaling approximately $66 million that are expected to be completed during 2018. Similar to previous years, the proposed projects consist of early vintage plastic and early vintage steel pipe, as well as the continuation of the previously approved COYL program in northern Nevada. Southwest entered into a settlement agreement with the intervening parties and filed a proposed stipulation requesting the Commission approve the settlement agreement. The settlement agreement proposed that the request be approved as filed and that Southwest be authorized to start replacing COYLs in southern Nevada in certain situations, and to recover costs through the GIR mechanism. The PUCN issued an Order on the GIR Advance Application in September 2017, approving approximately $65.7 million of replacement work (with an annualized revenue requirement estimated at approximately $6 million) and the COYL provisions in southern Nevada.

~~Subsequent to three GIR rate applications, the GIR~~final regulations require Southwest to either file a general rate case or a request for waiver before it can file another GIR advance application. The October 2016 approved rate application was the third such filing by Southwest subject to these regulations, necessitating a request for waiver to permit Southwest to proceed with the GIR program without filing a general rate case in 2017. This waiver waswere approved by the PUCN in January 2017; however, in order to continue the GIR program in 2018 (for projects recommended for completion under the program after 2018), a general rate case will need to be filed before June 2018.

~~Conservation and Energy Efficiency (“CEE”).~~ In June 2015, Southwest requested recovery of energy efficiency and conservation development and implementation costs, including promotions and incentives for various programs, as originally approved for deferral by the PUCN effective November 2009. While recovery of initial program costs was approved as part of the most recent general rate case, amounts incurred subsequent to May 2012 (the certification period) continued to be deferred. Approved rates for the~~post-May~~ 2012 costs deferred (including previously expected program expenditures for 2016) became effective January 2016 and resulted in annualized margin increases of $2 million in northern Nevada and $8.5 million in southern Nevada. Then, as part of the ARA filing approved in December 2016, Southwest modified rates, effective January 2017, expected to result in annualized margin decreases of $1.4 million in northern Nevada and $1.3 million in southern Nevada to return over-collected balances. There is, however, no anticipated impact to net income overall from these decreases as amortization expense will also be reduced.

~~Expansion and Economic Development Legislation.~~~~In February 2015,~~associated with legislation (“SB 151”) ~~was~~previously introduced and signed into law in ~~Nevada directing the PUCN to adopt regulations authorizing~~Nevada. The legislation authorized natural gas utilities to expand their infrastructure ~~consistent with a program of economic development. This includes providing gas~~to provide service to unserved and underserved areas in Nevada, as well as attracting and retaining utility customers and accommodating the expansion of existing business customers. SB 151 was signed into law in May 2015. The draft regulations were reviewed by the Legislative Council Bureau and final regulations were approved by the PUCN in January 2016.

Nevada.

In November 2017, Southwest filed for preapproval of a project to extend service to ~~include the service territory of~~ Mesquite, Nevada, in accordance with the SB 151 regulations. ~~This~~Ultimately, the PUCN issued an order approving Southwest’s proposal for the expansion. The order approved a capital investment of approximately $28 million and the construction of approximately 37 miles of distribution pipeline (including the approach main). The annual revenue requirement associated with the project is $2.8 million. A volumetric rate, applicable to all southern Nevada customers (including new customers in Mesquite), was implemented in October 2019 to recover the cost. Southwest’s May 2020 ARA filing, which proposes an annualized margin increase of $185,000, reflects the cumulative deferred revenue requirement associated with the Mesquite facilities that have been placed in service through April 30, 2020. During 2020, Southwest continued serving certain customers in Mesquite from an approved virtual pipeline network, providing temporary natural gas supply using portions of the approved distribution system and compressed natural gas. Construction of the remaining approved distribution system to bring the permanent natural gas supply to Mesquite has continued throughout 2020 and is planned to be placed in service in the fourth quarter of 2020.

In June 2019, Southwest filed for preapproval to construct the infrastructure necessary to expand natural gas service to Spring Creek, Nevada, and to implement a cost recovery methodology to timely recover the associated revenue requirement consistent with the SB 151 regulations. Expansion to the Spring Creek area near Elko, Nevada consists of a high-pressure approach main and associated regulator stations, an interior backbone, and the extension of ~~existing facilities~~the distribution system from the interior backbone system. The total capital investment is estimated to ~~Mesquite at an~~be $61.9 million. A stipulation in this matter was reached with the parties and approved by the PUCN in December 2019, which largely accepted Southwest’s proposal with modifications reflected in the rate recovery allocations split amongst northern Nevada, Elko, and Spring Creek expansion customers. Construction of the initial phase of the expansion began in the third quarter of 2020, with certain customers expected to be served by the end of the fourth quarter of 2020.

Customer Data Modernization Initiative.In March 2019, Southwest filed a request seeking authority to establish a regulatory asset to defer the revenue requirement related to the CDMI to mitigate the financial attrition associated with this multi-year project. Approximately $59 million of the estimated $174 million cost of ~~approximately $30 million. The cost is proposed~~the CDMI would be allocable to ~~be recovered through a volumetric surcharge on all southern~~the Nevada ~~customers.~~rate jurisdictions. A ~~second phase is then proposed to convert existing homes to natural gas service, which will be charged as a separate surcharge to Mesquite customers only. A decision~~hearing on this ~~proposal~~matter was held in August 2019 and the PUCN issued its decision in September 2019, denying Southwest’s request for regulatory asset treatment, finding that a general rate case is ~~expected within~~ the ~~required210-day~~ ~~time period for filings of this type.~~

~~Federal Energy Regulatory Commission (“FERC”) Jurisdiction~~

~~2018 Expansion.~~most appropriate venue to address such costs. In response to ~~growing demand~~the PUCN’s decision, Southwest filed a Petition for Reconsideration in October 2019, which was denied. As part of Southwest’s recently approved general rate case filing, Southwest was authorized to include CDMI costs since the beginning of the test year as part of its revenue requirement in the ~~Carson City and South Lake Tahoe areas~~case. The project is expected to be moved to production in 2021.

Regulatory Asset Related to COVID-19. The PUCN issued an order directing utilities within the state to establish regulatory asset accounts to track the financial impacts associated with maintaining service for customers affected by COVID-19, including those whose service would have been otherwise terminated/disconnected, effective March 12, 2020, the date that Governor Steve Sisolak declared a state of ~~northern California and northern Nevada,~~emergency related to COVID-19. These costs will be considered by the PUCN for future recovery.

The filing fulfilled an obligation from the settlement agreement reached in the 2014 Paiute general rate case. In January 2020, Paiute reached an agreement in principle with the FERC Staff and intervenors to settle its general rate case. In addition to continuing the term-differentiated rate structures with its shippers, the agreement requires Paiute’s three largest transportation ~~capacity~~customers and ~~executed precedent~~all of its storage customers to extend their service agreements ~~for incremental transportation capacity with Southwest during~~to have primary terms of at least five years. The settlement resulted in a revenue reduction of approximately $700,000 and is based on a 9.90% pre-tax rate of return. Also, as part of this agreement, Paiute agreed not to file a rate case prior to January 1, 2022, but no later than May 31, 2025.

In January 2020, Paiute requested, and was granted, the ~~third quarter of 2016. In October 2016,~~authority to place the settlement rates into effect on an interim basis, effective February 2020.

PGA Filings

The rate schedules in all of Southwest’s service territories contain provisions that permit ~~adjustments~~adjustment to rates as the cost of purchased gas changes. These deferred energy provisions and purchased gas adjustment clauses are collectively referred to as “PGA” clauses. Differences between gas costs recovered from customers and amounts paid for gas by Southwest result in over- or under-collections. At As of September 30, ~~2017, under-collections in Arizona and Northern Nevada resulted in an asset of approximately $6.2 million and~~2020, over-collections in ~~Southern Nevada and California~~each of Southwest’s service territories resulted in a liability of ~~$15~~$76.2 millionon the Company’s and Southwest’s condensed consolidated balance sheets. Gas cost rates paid to suppliers have been higher than amounts recovered from customers during the first nine months of 2017, resulting in fluctuations since December 31, 2016. Tariff rates have been adjusted in all jurisdictions during this period. Condensed Consolidated Balance Sheets.

Filings to change rates in accordance with PGA clauses are subject to audit by state regulatory commission staffs. PGA changes impact cash flows but have no direct impact on profit margin. However, gas cost deferrals and recoveries can impact comparisons between periods of individual consolidated income statement components. These include Gas operating revenues, Net cost of gas sold, Net interest deductions, and Other income (deductions).

Cash Flows

Southwest Gas Holdings, Inc.:

Operating Cash Flows.Cash flows provided by consolidated operating activities ~~decreased $179~~increased $109 million in the first nine months of ~~2017~~2020 as compared to the same period of ~~2016.~~2019. The ~~decline~~improvement in cash flows primarily resulted from collections of amounts under purchased gas adjustment mechanisms (compared to amounts refunded in the prior year), an increase in recoveries ($45 million) related to the Arizona decoupling mechanism balance between nine-month periods, as well as an increase in net income (including giving effect to depreciation and amortization). These impacts were partially offset by a $50 million supplemental contribution for pension funding made in January 2020 (included in Changes in other liabilities and deferred credits in the Condensed Consolidated Statements of Cash Flows of both the Company and Southwest). Utility accounts receivable collections generally are lower in the current year in light of Southwest’s temporary moratorium on disconnection of service amidst the COVID-19 environment, while improvement in cash flows resulted from changes in other working capital components. Customarily, differences between amounts Southwest pays to gas suppliers and amounts included in customer rates to recover the cost of purchased gas under the purchased gas cost mechanisms have provided significant variability in operating cash flows ~~was primarily attributable to the change in deferred purchased gas costs noted above.

The ~~increase~~change was primarily due to ~~activity~~a reduction in borrowings, and outstanding amounts, under the Company’s credit facility and Southwest’s long-term portion of the credit facility. Part of the net proceeds from the issuance of $450 million in Senior Notes in June 2020 by Southwest were used to pay down its credit facility and redeem $125 million of 4.45% Notes in September 2020. In the prior year, Southwest used a portion of the net proceeds from the $300 million Senior Notes issued in May 2019 to reduce amounts then outstanding under its credit facility and commercial paper ~~program (an increase~~program. Additionally, the Company issued $39 million more in borrowings in the current-year nine-month period and the repayment of borrowings in the prior-year nine-month period). The prior period included proceeds in utility operations from the issuance of $300 million in senior notes. The Company also issued approximately $12 million during 2017 incommon stock under the its Equity Shelf ~~Program. See also~~~~Note 5 – Common Stock~~~~, and the discussion below.

Southwest Gas Corporation:

Operating Cash Flows. Cash flows provided by operating activities increased $84 million in the first nine months of 2020 as compared to the same period of 2019. The improvement in operating cash flows was attributable to collections of deferred purchased gas costs and recoveries related to the Arizona decoupling mechanism noted above, as well as other working capital components overall, partially offset by the supplemental contribution for pension funding described earlier.

Investing Cash Flows. Cash used in investing activities decreased $55 million in the first nine months of 2020 as compared to the same period of 2019. The change was primarily due to a decrease in capital expenditures in 2020 offset by a decrease in utility customer advances toward capital projects. See also Gas Segment Construction Expenditures and Financing

below.

Financing Cash Flows. Net cash provided by financing activities decreased $142 million in the first nine months of 2020 as compared to the same period of 2019. The decline was primarily due to the combined effects of the repayment of previously accumulated outstanding balances under Southwest’s credit facility and the redemption of the $125 million in maturing Notes; and proceeds received from the issuance of $450 million Senior Notes in the current period, compared to the prior year issuance of $300 million in Senior Notes and repayment activity associated with the credit facility and commercial paper program.

Gas Segment Construction Expenditures and Financing

During the twelve-month period ended September 30, ~~2017,~~2020, construction expenditures for the natural gas operations segment were ~~$515~~$717 million. The majority of these expenditures represented costs associated with scheduled and accelerated replacement of existing transmission, distribution, and general plant. Cash flows from operating activities of Southwest were ~~$337~~$451 million during this time, and provided approximately ~~57%~~55% of construction expenditures and dividend requirements.

~~Southwest~~

Management estimates natural gas segment construction expenditures during the three-year period ending December 31, ~~2019~~2022 will be ~~between $1.6 billion and $1.8~~approximately $2.1 billion. Of this amount, approximately ~~$570~~$700 million is ~~expected~~scheduled to be incurred in ~~2017.~~2020. Southwest plans to continue ~~as appropriate,~~ to request regulatory support as necessary and appropriate to accelerate projects that improve system flexibility and reliability (including replacement of early vintage plastic and steel pipe). This includes the recent approval to complete accelerated replacement projects in Nevada of $57.3 million and $65.7 million in 2017 and 2018, respectively. It also incorporates programs included in the recently approved Arizona general rate case settlement (the continuation of the COYL program and implementation of a vintage steel pipe replacement program).reliability.

Any additional cash requirements are expected to be provided by existing credit facilities, equity contributions from the Company, and/or other external financing sources. The timing, types, and amounts of ~~any~~ additional external financings will be dependent on a number of factors, including the cost of gas purchases, conditions in the capital markets, timing and amounts of rate relief, timing differences between U.S. federal taxes embedded in customer rates and amounts implemented under tax reform, as well as growth levels in Southwest’s service areas and earnings. External financings ~~could~~may include the issuance of debt securities, bank and other short-term borrowings, and other forms of financing.

As noted earlier, in June 2020, Southwest issued $450 million aggregate principal amount of 2.20% Senior Notes at a discount of 0.126%. The notes will mature in June 2030. A portion of the net proceeds was used to reduce borrowings under Southwest’s credit facility and to redeem the 4.45% $125 million Notes that were maturing.

In ~~March 2017,~~May 2019, the Company filed with the ~~Securities Exchange Commission (“SEC”)~~SEC an automatic shelf registration statement for the offer and sale of up to ~~$150~~$300 million of common stock from time to time inat-the-market offerings under the prospectus included therein ~~and~~ in accordance with the Sales Agency Agreement, dated ~~March 29, 2017,~~May 8, 2019, between the Company and BNY Mellon Capital Markets, LLC (the “Equity Shelf Program”). ~~Sales~~The Company issued $33 million under this multi-year program during the third quarter of 2020; approximately $93 million remains available for issuance under the ~~shares will~~

Dividend Policy

Dividends are payable on the Company’s common stock at the discretion of the Board of Directors ~~(“Board”~~(the “Board”). In setting the dividend rate, the Board currently targets a payout ratio of 55% to 65% of consolidated earnings per share and considers, among other factors, current and expected future earnings levels, our ongoing capital expenditure plans and expected external funding needs, ~~our payout ratio, and~~in addition to our ability to maintain strong credit ratings and liquidity. The Company has paid dividends on its common stock since 1956 and has increased that dividend each year since ~~2007.~~2007. In February ~~2017,~~2020, the Board elected to increase the quarterly dividend from ~~$0.45~~$0.545 to ~~$0.495~~$0.570 per share, representing a ~~10%~~4.6% increase, effective with the June ~~2017~~2020 payment. ~~The Board currently targets a payout ratio of 55% to 65% of consolidated earnings per share.~~

Liquidity

Liquidity refers to the ability of an enterprise to generate sufficient amounts of cash through its operating activities and external financing to meet its cash requirements. Several ~~general~~ factors (some of which are out of the control of the Company) that could significantly affect liquidity in the future ~~years~~ include: variability of natural gas prices, changes in ~~the~~ ratemaking policies of regulatory commissions, regulatory lag, customer growth in the natural gas ~~segment’s service territories,~~segment, the ability to access and obtain capital from external sources, interest rates, changes in income tax laws, pension funding requirements, inflation, and the level of earnings.

gas prices and related gas cost recovery rates, as well as plant investment, have historically had the most significant impact on liquidity.

The Company remains focused on the safety and well-being of our employees and on service to our customers. The Company continues to review and assess the ongoing impacts of the COVID-19 pandemic, including those on our customers, suppliers, and business. As of September 30, 2020, the Company’s Cash and cash equivalents were $24 million, and the Company had access to $628 million of borrowing capacity under the Company’s various credit facilities, which management believes will help manage the impacts of the COVID-19 pandemic on its business and address related liquidity needs if they should arise.

On an interim basis, Southwest defers over- or under-collections of gas costs to PGA balancing accounts. In addition, Southwest uses this mechanism to either refund amounts over-collected or recoup amounts under-collected as compared to the price paid for natural gas during the period since the last PGA rate change went into effect. At September 30, ~~2017,~~2020, the combined balance in the PGA accounts totaled an over-collection of ~~$8.7~~$76 million. ~~See~~See PGA Filingsfor more information.

~~In March 2017,~~

Southwest ~~Gas Corporation amended its~~has a credit facility ~~increasing the~~with a borrowing capacity ~~from $300 million~~of $400 million; in April 2020, Southwest amended the credit facility agreement which extended the maturity date to April 2025. The revolving borrowing capacity under the amended credit facility agreement remains at $400 million ~~and extended the term of the facility from March 2021 to March 2022.~~following that amendment. Southwest ~~continues to designate~~designated $150 million of the facility for long-term borrowing needs and the remaining $250 million for working capital purposes. The maximum amount outstanding on the long-term portion of the credit facility (including a commercial paper program, as noted below) during the first nine months of ~~2017~~2020 was $150 million. AtAs of September 30, ~~2017, $150~~2020, $58 million was outstanding under the long-term portion of the facility. The maximum amount outstanding on the ~~long-term and $83 million~~short-term portion of the credit facility during the first nine months of 2020 was $194 million. As of September 30, 2020, no amount was outstanding on the short-term portion of this credit facility. The credit facility can be used as necessary to meet liquidity requirements, including temporarily financing under-collected PGA balances, if any, or meeting the refund needs of over-collected balances. ~~This credit facility~~It has been

adequate for Southwest’s working capital needs outside of funds raised through operations and other types of external financing.

As indicated, any additional cash requirements would include the existing credit facility, equity contributions from the Company, and/or other external financing sources.

Southwest has a $50 million commercial paper program. Any issuance under the commercial paper program is supported by Southwest’s current revolving credit facility and, therefore, does not represent additional borrowing capacity. Any borrowing under the commercial paper program during 2020 will be designated as long-term debt. Interest rates for the commercial paper program are calculated at the current commercial paper rate during the borrowing term. At September 30, ~~2017, no borrowings were~~2020, there was $50 million outstanding under this program.

Centuri has a ~~$300 million~~senior secured revolving credit and term loan facility ~~that is scheduled~~with borrowing capacity of $590 million (refer to ~~expire in October 2019.~~Note 5 – Debt). The line of credit portion comprises $325 million; associated amounts borrowed and repaid are available to be re-borrowed. The term loan facility portion had an initial limit of approximately $150 million, which was reached in 2014 and; $107 million was outstanding (after repayments) at September 30, 2017. The secured revolving credit facility portion also has a limit of ~~$150 million; amounts borrowed~~approximately $265 million. The $590 million credit and ~~repaid~~term loan facility expires in November 2023. It is secured by substantially all of Centuri’s assets except those explicitly excluded under ~~this portion~~the terms of the agreement (including owned real estate and certain certificated vehicles). Centuri assets securing the facility ~~are available to bere-borrowed.~~ ~~The~~at September 30, 2020 totaled $1.4 billion. The maximum amount outstanding on the ~~credit~~ facility during the first nine months of ~~2017~~2020 was ~~$104 million. At September 30, 2017, $81.3~~$312 million, at which point $235 million was outstanding on the ~~secured~~term portion. As of September 30, 2020, $60 million was outstanding on the revolving credit facility and $231 million was outstanding on the term loan portion of the facility. Also at September 30, ~~2017,~~2020, there was approximately ~~$52~~$240 million, net ofof letters of credit, available under the line of credit.

~~The following table sets forth the ratios of earnings to fixed charges~~

Interest rates for the ~~Company. Due~~amended credit facilities of the holding company and Southwest are calculated at either LIBOR or an “alternate base rate,” plus in each case an applicable margin determined based on each entities’ respective senior unsecured long-term debt rating. Upon the occurrence of certain events providing for a transition away from LIBOR, or if LIBOR is no longer a widely recognized benchmark rate, each entity may amend their respective credit facility with a replacement rate as set forth in the amended credit facility agreement. It is currently anticipated that LIBOR may be discontinued as a benchmark or reference rate after 2021. As of September 30, 2020, $54 million, $8 million, and $172 million, respectively, for the holding company, Southwest, and Centuri were outstanding under credit facility arrangements with interest rates in reference to LIBOR and maturity dates extending beyond 2021. Combined, these reflect approximately 0.3% of Southwest’s total debt, and 8% of total Company debt overall. In order to mitigate the impact of the discontinuation on the Company’s financial condition and results of operations, management will continue to monitor developments with respect to alternative rates and work with lenders to determine the appropriate alternative reference rate for variable rate indebtedness. However, at this time the Company and Southwest can provide no assurances as to the ~~seasonal nature~~impact a LIBOR discontinuation will have on their financial condition or results of ~~the Company’s business, these ratios are computed on a twelve-month basis:~~

~~CONTROLS AND PROCEDURES~~

ITEM 4. CONTROLS AND PROCEDURES

Management of Southwest Gas Holdings, Inc. and Southwest Gas Corporation has established disclosure controls and procedures (as defined in Rules13a-15(e) and15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) that are designed to provide reasonable assurance that information required to be disclosed in their respective 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 to provide reasonable assurance that such information is accumulated and communicated to management of each company, including each respective Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and benefits of controls must be considered relative to their costs. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or management override of the control. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and may not be detected.

Based on the most recent evaluation, as of September 30, ~~2017,~~2020, management of Southwest Gas Holdings, Inc., including the Chief Executive Officer and Chief Financial Officer, ~~believe~~believes the Company’s disclosure controls and procedures are effective at attaining the level of reasonable assurance noted above.
