SOUTHWEST GAS HOLDINGS, INC.						Form 10-Q
SOUTHWEST GAS CORPORATION						March 31, ~~2020~~2021

Note 1 – Background, Organization, and Summary of 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 all of the shares of common stock of Centuri Group, Inc. (“Centuri,” or the “utility infrastructure services” segment).

Southwest 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 utility infrastructure services enterprise dedicated to delivering a diverse array of solutions to North America’s gas and 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”), New England Utility Constructors, Inc. (“Neuco”), and Linetec Services, LLC (“Linetec”). Utility infrastructure services activity is seasonal in most of Centuri’s operating areas. Peak periods are the summer and fall 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 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 U.S. generally accepted accounting principles (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations. No substantive change has occurred with regard to the Company’s business segments on the 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. 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 depiction of results for the interim periods, have been made. ~~Globally,~~In association with the novel Coronavirus (“COVID-19”) pandemic ~~has created volatility, uncertainty,~~environment, utility operations, and ~~economic disruption. Utility operations~~to a large extent, utility infrastructure services, have been deemed “essential ~~services” and utility infrastructure services have, to a large extent, been similarly characterized by government officials.~~services.” Management has considered the impact of the pandemic and adjusted certain estimates, where relevant, used in the preparation of the condensed consolidated financial statements.

~~It is suggested that these~~These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and ~~the~~ notes thereto included in the ~~2019~~2020 Annual Report to Stockholders, which is incorporated by reference into the ~~2019~~2020 Form 10-K.

Fair Value Measurements. Certain assets and liabilities are reported at fair value, which is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at 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 establishes a fair value hierarchy that ranks the inputs used to measure fair value by their reliability. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to fair values derived from unobservable inputs (Level 3 measurements). Financial assets and liabilities are categorized in their entirety based on the lowest level of input that is significant to the fair value measurement. The three levels of the fair value hierarchy 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 extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at the measurement date.

SOUTHWEST GAS CORPORATION						March 31, ~~2020~~2021

The Company primarily used quoted market prices and other observable market pricing information in valuing cash and cash equivalents, ~~derivatives,~~ long-term debt outstanding, and assets of the qualified pension plan and postretirement benefit plans required to be recorded and/or disclosed at fair value.

Other Property and Investments. Other property and investments on the Condensed Consolidated Balance Sheets includes:

Included in the table above are the net cash surrender values of company-owned life insurance (“COLI”) 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 ~~for~~of Southwest and the Company ~~also~~ include money market fund investments totaling approximately $40,000 ~~and $49,000, respectively,~~for each entity at March 31, ~~2020,~~2021 and ~~$23.5 million and $26.7 million, respectively, at~~ December 31, ~~2019,~~2020, respectively, 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, and capital expenditures that were not paid as of ~~period end~~period-end reporting dates, but rather included in accounts ~~payable,~~payable. Typical activities that represent aspects of both non-cash investing and ~~right-of use~~non-cash financing activities relate to right-of-use assets obtained in exchange for lease liabilities ~~which are non-cash investing~~(including, at times, lease terminations and ~~financing activities.~~modifications). Amounts related to ~~such~~these collective 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. On January 2, 2020, the Company adopted the Financial Accounting Standards Board’s (the “FASB”) Accounting Standards Update (“ASU”) 2016-13 “Financial Instruments—Credit Losses: Measurement of Credit Losses on Financial Instruments,” which replaces the incurred loss methodology with an expected loss methodology that is referred to as the current expected credit loss, or CECL, methodology. The Company adopted ASU 2016-13 using the modified retrospective method, and therefore, results for reporting periods beginning prior to January 1, 2020 are presented under previously accepted U.S. GAAP. See ~~Recent Accounting Standards Updates~~ ~~below.~~

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~~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 ~~payments~~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, ~~and as utility service is an essential service to~~Southwest continued the ~~residents~~moratorium initiated in ~~the states in which Southwest operates, Southwest implemented a temporary moratorium~~March 2020 on disconnection of natural gas service for non-payment, ~~and it also ceased charging~~but recommenced assessing late fees ~~until further notice.~~in Nevada and Arizona in April 2021, with late fees in California expected to recommence in the latter half of 2021. Southwest is ~~also~~ actively working with customers experiencing financial hardship by means of flexible payment options. Management ~~is monitoring~~continues to monitor expected credit losses in light of the evolving ~~financial~~ impact of ~~COVID-19, and has adjusted the~~COVID-19. The allowance ~~for uncollectibles~~ as of March 31, ~~2020~~2021 reflects the expected impact from the pandemic on balances as ~~a result~~ of ~~the anticipated impact on Southwest’s~~that date, including consideration of customers’ ability to pay ~~amounts due both~~ currently and ~~when~~once the moratorium on disconnections is lifted. The adjustment was not material to the financial statements overall, and entering the summer season, during which time monthly billing amounts are substantially reduced, management does not expect a material increase to the allowance for uncollectibles.

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 forward-looking estimated 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.

~~Income Taxes.~~

Deferred Purchased Gas Costs. The various regulatory commissions have established procedures to enable Southwest to adjust its billing rates for changes in the cost of natural gas purchased. The difference between the current cost of gas purchased and the cost of gas recovered in billed rates is deferred. Generally, these deferred amounts are recovered or refunded within one year.

In mid-February 2021, the central U.S. (from south Texas to North Dakota and the eastern Rocky Mountains) experienced extreme cold temperatures, which increased natural gas demand and caused supply issues due to wellhead freeze-offs, power outages, or other adverse operating conditions upstream of Southwest’s distribution systems. These conditions caused daily natural gas prices to reach unprecedented levels. During this time, Southwest secured natural gas supplies, albeit at substantially higher prices, maintaining service to its customers. The incremental cost for these supplies was approximately $250 million, funded using a 364-day $250 million Bank Term Loan executed in March 2021 (see ~~On March 27, 2020,~~Note 5 – Debt).The incremental gas costs are expected to be collected from customers through the ~~Coronavirus Aid, Relief,~~purchased gas adjustment (“PGA”) mechanisms.

Following the extreme weather event, an interstate transmission pipeline company billed Southwest, in addition to customary transmission costs, $65 million for pipeline imbalance charges, allegedly incurred during the period of the pipeline’s critical operation condition. However, Southwest has formally disputed these imbalance charges 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 relatedbelieves that no amounts are due to the ~~employer portion~~pipeline. Consequently, Southwest has not recognized this charge. Pipeline transmission costs, including periodic imbalance charges, are components of ~~Social Security taxes,~~the cost of gas recovered from customers through the PGA and the creation of certain refundable employee retention credits, among other things. Management does not anticipate the impacts, if any, related to the CARES Act to have a material effect on the Company’s or Southwest’s results of operations, financial position, or liquidity.similar mechanisms.

Prepaid and other current assets. Prepaid and other current assets includes gas pipe materials and operating supplies of ~~$53~~$47 million at March 31, ~~2020~~2021 and ~~$57~~$50 million at December 31, ~~2019~~2020 (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 March 31, 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,~~2020, management also qualitatively assessed whether events during the ~~1st quarter~~first three months of ~~2020~~2021 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 in~~occurred. Goodwill on Southwest’s and the ~~first three months of 2020.~~Company’s Condensed Consolidated Balance Sheets includes:

Included in the table above is the change in cash surrender values of COLI policies (including net death benefits recognized). Current tax regulations provide for tax-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. Refer to Other Property and Investments above and also to Note 2 – Components of Net Periodic Benefit Cost.

~~Derivatives~~. In 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 future at a fixed price, qualify for the 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 fair value reporting. The 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 longest maturity date of the Swaps as of March 31, 2020 is October 2020.~~

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 purchase gas adjustment (“PGA”) mechanism in determining the deferred PGA balances. Neither changes in fair value nor settled amounts of Swaps have a direct effect on earnings or other comprehensive income, since following settlement, amounts are reflected in Net cost of gas sold at the same time they are included in Gas operating revenues through updates to the PGA component of rates.

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, which were immaterial at March 31, 2020. There was no outstanding collateral associated with the Swaps during any period reflected on the Condensed Consolidated Balance Sheets.

Previously, Southwest entered into forward-starting interest rate swaps (“FSIRS”), the settled positions for which are immaterial and continue to be amortized from Accumulated other comprehensive income (loss) into interest expense.

Redeemable Noncontrolling Interest. In connection with the acquisition of Linetec in November 2018, the previous owner retained a 20% equity interest in Linetec, the reduction of which is subject to certain rights based on the passage of time or upon the occurrence of certain triggering events.

Significant changes in the value of the redeemable noncontrolling interest, above a floor established at the acquisition date, are recognized as they occur, and the carrying value is adjusted as necessary at each reporting date. The fair value is estimated using

Recent Accounting Standards Updates.

Accounting pronouncements adopted in ~~2020:~~

In June 2016, the FASB issued ASU 2016-13 update “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” The update requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. The Company and Southwest adopted the update in the first quarter of 2020, and concluded the impact was not material to the condensed consolidated financial statements of the Company or Southwest. See ~~Accounts receivable, net of allowances~~ ~~above.~~

In January 2017, the FASB issued ASU 2017-04 “Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.” Under the update, an entity will apply a one-step quantitative test as opposed to a two-step test as currently required, and record the amount of goodwill impairment as the excess of a reporting unit's carrying amount over its fair value, not to exceed the total amount of goodwill allocated to the reporting unit. The new guidance does not amend the optional qualitative assessment. The Company and Southwest adopted the update in the first quarter of 2020 and will apply the update prospectively in any future goodwill impairment tests.

In August 2018, the FASB issued ASU 2018-15 “Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract.” The update generally aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement (that is a service contract) with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software, with the exception that such costs are to be included in the same line item in the balance sheet that a prepayment of the fees associated with the arrangement would be presented. Once capitalized, the update requires the entity to expense the amount capitalized over the term of the hosting arrangement, including reasonably certain renewal periods. The Company and Southwest adopted the update in the first quarter of 2020 using the prospective transition method. There were no material implementation costs related to cloud computing arrangements for the Company and Southwest in the first quarter of 2020.

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.

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~~service cost to the same accounts to which productive labor is charged. As a result, 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. The other components of net periodic benefit cost are reflected in Other income (deductions) on the Condensed Consolidated Statements of Income of each entity.

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~~2020 to March 31, ~~2020~~2021 is due to revenue recognized of $4.5 million ~~that~~that was included in this item as of January 1, ~~2020,~~2021, 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 less, Centuri uses the practical expedient applicable to such contracts and does not consider/compute an interest component based on the time value of money. Further, because of the 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 March 31, ~~2020,~~2021, Centuri had ~~23 contracts~~18 contracts with an original duration of more than one year. The aggregate amount of the transaction price allocated to the unsatisfied performance obligations of these contracts as of March 31, ~~2020~~2021 was ~~$68.2 million.~~$48.7 million. Centuri expects to recognize the remaining performance ~~obligations~~obligations over approximately the next two years; ~~however,~~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.

The fair values of ~~the~~Southwest's revolving credit facility and 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 and medium-term notes) were determined utilizing a market-based valuation approach, where fair values are determined based on evaluated pricing data, ~~such~~and 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.

~~On April 10, 2020, Southwest amended its~~facility and $17 million of borrowings were outstanding on the short-term portion of this credit facility agreement; total borrowing capacity under the amended agreement remains $400 million. The amended agreement extends the maturity date from March 2022 to April 2025. Interest rates for the facility are calculated at either LIBOR or an “alternate base rate,” plus in each case an applicable margin determined based on Southwest’s senior unsecured long-term debt rating. The applicable margin ranges from 0.750% to 1.500% for loans bearing interest with reference to LIBOR and from 0.000% to 0.500% for loans bearing interest with reference to an alternate base rate. 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 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.

~~LIBOR~~

ItLIBOR

LIBOR is ~~currently anticipated that LIBOR may~~scheduled to be discontinued as a benchmark or reference rate after 2021.

These amounts reflect approximately 11% of Southwest’s total debt, and 18% of total debt (including current maturities) for the Company overall. Southwest and Southwest Gas Holdings, Inc. (see above) in amending their respective facilities in April 2020 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

(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).

Operating margin increased ~~$14~~$24 million. Approximately $5$6 million of incremental margin was attributable to customer growth ~~as 33,000 net new customers were added~~from 37,000 first-time meter sets during the last twelve ~~months. Rate~~months, while rate relief ~~primarily in California, contributed $1~~added $18 million in incremental operating margin in the current quarter. The prior-year quarter included an approximate $5 million reduction in margin resulting from a one-time adjustment by the Arizona Corporation Commission (the “ACC”) to reflect theof margin. Offsetting these increases were impacts ~~of U.S. tax reform on the Arizona decoupling mechanism. The remaining increase primarily resulted~~ from the ~~net recovery of regulatory program balances (collectively, having an offsetting impact~~temporary moratorium on late fees initiated by Southwest in ~~amortization expense)~~March 2020 ($2.6 million), in addition to lower connection/re-connection charges, as a result of the COVID-19 pandemic. Amounts returned to and collected from customers associated with regulatory account balances, as well as differences in miscellaneous revenue and margin from customers outside the decoupling mechanisms, ~~and other miscellaneous revenues.~~also impacted the variance between periods.

Operations and maintenance expense ~~decreased $2.5 million between quarters. Lower pipeline integrity management costs and legal claims experience contributed to the decline between periods.~~

~~Depreciation and amortization expense~~ increased ~~$7.1~~$3 million, or ~~12%~~3%, between quarters primarily due to an increase in the service-related component of employee pension cost and other benefits, increased expenditures for pipeline damage prevention programs, and increased legal claim-related costs, offset by lower training and travel costs as a ~~$684~~result of the current COVID-19 environment.

Depreciation and amortization expense increased $4 million, or ~~10%~~6%, between quarters, primarily due to a $546 million, or 7%, increase in average gas plant in service compared to the corresponding quarter a ~~year ago, and to an increase~~year ago. Amortization of regulatory program balances impacted expense in ~~regulatory account amortization, as discussed above.~~both periods. The increase in gas plant was attributable to pipeline capacity reinforcement ~~work,~~work, franchise requirements, scheduled ~~and accelerated~~ pipe replacement activities, and new infrastructure.

~~Other~~Taxes other than income ~~decreased $26.5~~taxes increased $4.3 million between quarters primarily due to ~~a decline~~an increase in Arizona property taxes.

Other income improved $21.1 million between quarters primarily due to an increase in income from ~~company-owned life insurance (“COLI”)~~COLI policies.

Utility infrastructure services revenues increased ~~$196.5~~$207.2 million, ~~overall~~or 12%, in the current twelve-month period compared to the corresponding period of ~~2019,~~2020, primarily due to incremental electric infrastructure revenues of $165.7 million from expansion of work with existing customers and securing work with new customers. Included in the incremental electric infrastructure revenues during the twelve-month period of 2021 was $90.5 million from emergency restoration services performed by Linetec, ~~(acquired~~following hurricane, tornado, and other storm damage to customers’ above-ground utility infrastructure in ~~November 2018)~~and around the Gulf Coast and eastern regions of ~~$192.2~~the U.S., as compared to $13.2 million ~~as well as~~in similar services during the twelve-month period in 2020. Centuri’s revenues derived from storm-related services vary from period to period due to the unpredictable nature of weather-related events. The remaining increase in revenue was attributable to continued growth with existing gas infrastructure customers under master service and bid agreements. Partially offsetting these increases were decreased revenues from certain non-routine projects, including customer-requested support in 2018 and early 2019 during strike-related and emergency response situations, in addition to a multi-year water pipe replacement project that expired in July 2019 and was not renewed. The prior-year period also included the settlement of an earlier contract dispute related to that project ($9 million). Implementation of new regulatory requirements for operating locations within certain eastern states in the U.S. resulted in lower revenues during the current period as Centuri worked with customers to adopt the new requirements.

Utility infrastructure services ~~expenses~~expenses increased ~~$162.9~~$153.7 million ~~between~~ between periods, ~~primarily~~largely due to incremental expenses related to ~~Linetec of $157.6 million along with additional~~ electric infrastructure ~~and pipe replacement~~ work ~~and higher labor-related operating expenses to support growth in operations.

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 ~~the~~ 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. OnIn May 1, 2019, Southwest filed a general rate case application requesting to increase revenue by approximately $57 million to update the cost of service to reflect recent U.S. tax reform changes, ~~including~~incorporating the return of excess deferred income taxes to customers, and to reflect capital investments, ~~of approximately $670 million,~~ including certain post-test year additions ~~which include~~and the southern Arizona ~~LNG facility discussed below.~~liquefied natural gas (“LNG”) facility. The application ~~also includes~~included a proposed 10.3% return on equity (“ROE”) relative to a capital structure of 51.1% equity. AtSouthwest updated its request to reflect the time of the filing, the Company estimated the return of approximately $20.6 million of excess deferred income taxes. Following the original filing, in October 2019, Southwest filed an amendment to its application, updating for $5.7 million in actual amortization of excess accumulated deferred income taxes ~~known after the Company’s 2018 federal income~~(“EADIT”) resulting from U.S. tax ~~return was filed in 2019, at which point, the actual amount could be computed based on the prescribed methodology for computing the amount that could be returned~~reform, and to customers. The difference of $14.9 million would result in an increase in revenue and income tax expense, thereby having no impact on earnings overall. In association with the amendment, Southwest also includedinclude additional post-test year plant ~~in the amount of $124.5 million~~ associated with its ~~COYL~~customer-owned yard line (“COYL”) and ~~VSP~~vintage steel pipe (“VSP”) programs, discussed further below. The amendment ~~overall~~ increased the deficiency by $36 million, to $93 ~~million. Through the exchange of discovery and following the exchange of testimony, Southwest~~million, which was further updated to $90.6 million based on certain aspects of ~~its~~ cost of service, including a revised proposed ROE of 10.15%~~, to reflect an updated proposed increase of $90.6 million. It also includes~~. The request and amendments included the retention of a fully decoupled rate design, other previously approved regulatory mechanisms, and a new infrastructure tracking mechanism for specific plastic ~~pipe. The request also includes~~pipe, in addition to a proposal for a renewable natural gas (“RNG”) program ~~that authorizes Southwest to purchase renewable natural gas for its customers and to recover the cost~~ as part of its PGA mechanism. ~~A hearing in this matter was previously scheduled~~Southwest entered into a stipulation for ~~April 2020; however, due to the current status~~certain aspects of the ~~COVID-19 pandemic,~~case, agreeing to continue the COYL program; to establish a Tax Expense Adjustor Mechanism to track annual changes in the amortization of EADIT, as well as any future changes in the federal tax rate; to include a 10-year amortization of EADIT associated with deemed “unprotected” plant; and to incorporate various tariff proposals. 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. Following the hearing ~~will be reset at~~and legal briefing process, this requested amount was further updated to $80.7 million to reflect agreements by the parties on the treatment of EADIT and certain other ratemaking adjustments.

A final decision was issued in December 2020, with new rates becoming effective in January 2021, resulting in an overall annual revenue increase of $36.8 million, and the continuation of both full revenue decoupling and the COYL program. An ROE of 9.1% was approved with a ~~later date.~~capital structure comprised of 48.9% long-term debt and 51.1% common equity. The overall increase reflects the final ROE and the inclusion of a six-month period covering certain post-test year plant additions, as well as the post-test year plant addition of the LNG facility. See additional discussion related to these programs below. The continuation of the property tax tracker was supported in the final decision, as was the Tax Expense Adjustor Mechanism (noted above). While the RNG proposal was not approved as part of the decision, the ACC agreed to conduct a workshop to further explore the role of RNG in Arizona.

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. The DCA rate adjustment request filed in April 2018 reflected the December 31, 2017 balance, but was later updated to include the balance at December 31, 2018; after a one-time modification to reflect benefits attributable to the impact of U.S. tax reform on the balance then existing, the ACC approved an annualized recovery of $69 million, with the associated rate effective in May 2019. 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.~~

~~Tax Reform.~~ ~~In February 2018,~~2020, proposing a rate of $0.00655 per therm based on an ending balance of approximately $3.5 million. Although Commission Staff concurred with Southwest’s proposed rate, the ACC ~~directed all Arizona utilities~~ultimately elected to ~~address tax savings from~~reduce the ~~enactment~~rate to zero in an effort to provide some measure of ~~U.S. tax reform beginning January 1, 2018, through one~~customer relief in light of ~~various means.

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 a modest under-collected balance at December 31, 2020, and an ~~asset~~over-collected balance of ~~$1.5~~$9.5 million exists as of March 31, ~~2020.~~2021.

~~Liquefied Natural Gas (“LNG”)~~LNG Facility. In ~~January~~ 2014, Southwest ~~filed an application with the~~sought ACC ~~seeking~~ 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 related to natural gas deliveries in the southern Arizona area by providing a local storage option, and to be connected directly to Southwest’s

~~Customer-Owned Yard Line (“COYL”)~~COYL Program. Southwest received approval, in connection with 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, representing a non-traditional configuration. In 2014, the ACC approved a “Phase II” of the COYL program, which included the replacement of non-leaking COYLs. ~~The surcharge is~~Annual surcharges were designed to collect the ~~annual~~ revenue requirement asassociated with the ~~program progresses.~~program. In ~~the filing made in~~a February 2019 filing, Southwest requested to increase its surcharge to recover a revenue requirement of $6.7 million (an increase of $3.2 million) ~~related to the revenue requirement~~ associated with $26.6 million in capital projects completed in 2018. The ACC ultimately issued an Order in October 2019 authorizing Southwest to retain the existing annual surcharge ~~of $3.5 million and indicating~~in place, while it ~~would review~~reviewed the program as part of the ~~pending~~ general rate case. ~~Neither the ACC Staff nor the consumer advocate oppose the continuation of the COYL program.~~ Southwest also ~~proposed to have the ACC review~~included an estimated $21.1 million ofrelated to the 2019 COYL capital projects ~~and if authorized, to also render a decision regarding cost recovery~~ as part of the ~~pending~~rate case. Parties to the rate case stipulated to continue the COYL program and recommended recovery of the plant as part of Southwest’s filed post-test year plant adjustment, with inclusion of related amounts in base rates. Further consideration in the rate case decision limited post-test year plant to six months (inclusive of COYL plant), and limited future COYL activity to the replacement of leaking COYLs, or in cases when other replacement activity is taking place in the vicinity. A filing in the second quarter of 2021 will propose the recovery of the revenue requirement associated with the 2019 and 2020 COYL activity and plant placed in service following the six-month post-test year inclusion period of the recently concluded rate case.

~~Vintage Steel Pipe (“VSP”)~~VSP Program. Southwest received approval, in connection with its 2016 Arizona general rate case, to implement a VSP replacement ~~program. Southwest currently has~~program, due to having a substantial amount of pre-1970s vintage steel pipe in Arizona. As part of the program, Southwest proposed to ~~start~~begin replacing the pipe on an accelerated basis and to recover the costs through an annual surcharge filing. ~~A surcharge related thereto has been customarily designed to be revised annually as the program progresses~~Once implemented, surcharges to collect the annual revenue requirement associated with the ~~related~~ capital ~~expenditures.~~expenditures were designed to be revised annually under the program. In ~~the most recent VSP filing, in~~ February 2019, Southwest requested to increase its surcharge revenue by $9.5 million (to $11.9 million) ~~related to 2018 expenditures; Southwest replaced~~associated with the replacement of approximately $100 million ~~of VSP~~ in ~~connection with~~ 2018 VSP capital projects. The ACC issued an Order in October 2019 authorizing Southwest to retain the ~~current~~existing annual surcharge, ~~of $2.4 million~~ and indicated it would review the program as part of the ~~pending~~general 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 noted above, the decision in the general rate case provided for a post-test year plant adjustment period of six months (inclusive of VSP). However, the ACC ultimately decided to discontinue the accelerated VSP program at this time. A filing in the second quarter of 2021 will propose the recovery of the revenue requirement associated with the 2019 and 2020 VSP activity and plant placed in service following the six month post-test year inclusion period of the recently concluded rate case.

Customer Data Modernization Initiative. Southwest ~~has~~ embarked on an initiative to replace its customer service system and ~~its~~ gas transaction ~~system,~~systems, each ~~of which is~~to be 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 commission issued a decision in this matter in early April 2021 denying Southwest’s request for a regulatory asset, indicating that the requested recovery mechanism was not warranted. Therefore, the costs will be considered as part of a future general rate proceeding. The total cost for the CDMI iswas estimated at approximately $174 million, ~~approximately~~ $96 million of which would be allocable to the Arizona rate jurisdiction. The ~~initiative is currently expected to be completed~~customer service system was placed in service in May 2021 and the ~~first half of~~gas transaction system will follow later in 2021. ~~A hearing in this matter was previously scheduled for April 2020; however, due to the current status of the COVID-19 pandemic, a hearing in this matter will be reset at a later date.~~

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 2.75% annually for 2015 through 2018, after which new rates from a subsequent rate case cycle would have been expected to be in effect. In ~~December 2016,~~August 2019, Southwest filed ~~to modify the earlier (2014)~~a general rate case ~~decision~~based on a 2021 test year, seeking authority to increase rates in its California rate jurisdictions, after being granted earlier permission to extend the rate case cycle by two years and ~~received CPUC approval in June 2017, including extension of the annual~~continue its 2.75% ~~PTY~~previously approved Post-Test Year (“PTY”) attrition adjustments for 2019 and 2020.

~~On August 30, 2019, Southwest filed the previously deferred California 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 iswas net of a $10.9 million revenue reduction associated with changes from U.S. tax reform, which ~~includes~~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, ~~(as discussed below),~~ which when returned ~~will~~would impact cash flows, but is not expected to have an impact on ~~earnings overall.~~earnings.

Although new rates were originally anticipated to be in place by January 1, 2021, in light of an administrative delay, Southwest was granted authority to track income tax expense resulting from mandatory or elective changes in tax law, procedure, or policy. The purpose is to identify differences between Southwest’s authorized income tax expense and its actual incurred income tax expense, the result of which would be reviewed in Southwest’s now currently applicableestablish a general rate case ~~application.

Greenhouse Gas (“GHG”) Compliance. California Assembly Bill Number 32 and ~~the~~ regulations promulgated by the California Air Resources Board, require Southwest, as a covered entity, to comply with ~~all~~ applicable requirements associated with California GHG emissions reporting and the California Cap and Trade Program. The CPUC issued a decision in ~~March~~ 2018 adopting an allocation methodology to distribute the net revenues or ~~costs for years 2015-2017 beginning in the second quarter of 2018.~~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 ~~(including transportation customer rates)~~ have no impact on earnings.

Renewable Natural Gas. In February 2019, Southwest filed an application that, among other ~~provisions, seeks~~things, sought to formally allow ~~the inclusion of~~ renewable natural gas (or biomethane) as ~~a potential~~an includible component of Southwest’s gas supply portfolio through the Biomethane Gas Program (“BGP”). This proposal iswas 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 ~~the end of~~in March 2020.

Customer Data Modernization Initiative. OnIn 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 ~~cost~~ for the CDMI would be allocable to the California rate jurisdiction. Southwest filed a separate request to establish a memorandum account while the CPUC ~~considers~~considered its application request to establish athe two-way balancing account. Effective October 2019, the CPUC granted Southwest’s memorandum account request, which ~~will~~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 ~~CMDI.~~CDMI. The balance tracked in the memorandum account ~~will~~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 Application ~~for Authority to Implement~~and the ~~CDMI.

Emergency Relief Program Related to COVID-19. OnIn March ~~25,~~ 2020, in light of the COVID-19 pandemic, Southwest ~~filed an Advice Letter~~requested to establish a memorandum account to track costs ~~related to the implementation~~as part of customer protections under Emergency Relief regulations implemented in California in 2019 in(in the event of a state or federal declared emergency or ~~disaster.~~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 ~~associated with~~of complying with the resolution. On May 1, 2020, Southwest ~~filed an Advice Letter~~requested 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 iswas originally effective March 4, 2020 through April 16, 2021, but was extended through June 30, 2021. These customer protections focus on flexible payment plan options, additional

Rates ~~from this proceeding originally~~ became effective in ~~January 2019.~~October 2020.

~~As part of that proceeding,~~In association with the previous Nevada rate case decision in December 2018, management ~~filed a request for~~requested reconsideration of several ~~rate case~~ issues ~~during~~in the ~~same month of effective rates. The~~case; however, the PUCN Staff also filed a Petition for Reconsideration requesting several technical clarifications on the rate case decision with respect to how to calculate the intended results of the decision. The PUCN, in turn, issued a decision regarding both petitions in February 2019 that modified certain parts of the original order, butultimately granted no further rate relief. The modified final decision resulted in a revenue increase of $9.2 million in southern Nevada and a revenue decrease in northern Nevada of $2.1 million. The decision included a reduction in depreciation expense of $800,000 and overall, resulted in a net increase in revenues of $7.1 million and an increase in operating income of $7.9 million. The modified rates became effective 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, Southwest filed an appeal with the Nevada Supreme Court, which remains active; the resolution ~~of which~~ will likely take 12-24 ~~months. Southwest expects consideration~~months from the date of the ~~appeal to occur concurrently with the proceedings of the 2020 general rate case that was filed in February 2020.~~appeal.

General Revenues Adjustment. The continuation of the GRA was affirmed as part of ~~the December 2018 rate case decision and is again being requested as part of~~ Southwest’s ~~pending~~recently concluded general rate case, ~~application filed in February~~effective October 2020. Southwest makes Annual Rate Adjustment (“ARA”) filings to update rates to recover or return amounts associated with various regulatory mechanisms, including the GRA. In June 2019, Southwest made its ~~2019 Annual Rate Adjustment (“ARA”)~~annual filing, in which ~~it requested to update the GRA to reflect the current balances in both southern and northern Nevada. This most recent filing~~ provided for a decrease of approximately $8 million for an over-collected balance in southern Nevada and an increase of approximately $2 million in northern Nevada. The proposed changes were approved, with rates effective January 2020. In May 2020, Southwest made its most recent ARA filing, which proposed an annualized margin decrease of $5.3 million in southern Nevada and an increase of $1.6 million in northern Nevada. The ARA filing was resolved through a settlement of the parties, in which the proposed changes associated with the GRA were approved, effective January 2021. While there is no impact to net income overall from adjustments to recovery rates associated with the related regulatory balances, operating cash flows are impacted by such changes.

Infrastructure Replacement Mechanism. In 2014, the PUCN approved final rules for the GIR mechanism, which defers and ~~recovers~~provides for recovery of certain costs associated with accelerated replacement of qualifying infrastructure that would not otherwise currently provide incremental revenues. Associated with the replacement of various types of pipe infrastructure under the mechanism (Early Vintage Plastic Pipe, COYL, and VSP), the related regulations provide Southwest with the opportunity to file a GIR “Advance Application” annually, generally in May, to seek preapproval of qualifying replacement projects.

Furthermore, a GIR ~~Rate Application~~rate application is generally filed each October to reset the GIR recovery surcharge rate related to previously approved and completed projects, with new rates typically becoming effective each January. On October 1, 2019, Southwest filed a ~~Rate Application~~rate application to reset the recovery surcharge to include cumulative deferrals through August 31, 2019. This surcharge rate became effective February 1, 2020, ~~and is expected~~designed to result in a reduction in annual revenue of approximately $5.3 million in southern Nevada and no incremental revenue in northern ~~Nevada~~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 updated surcharge rate is expected to result in a reduction in annual revenue of approximately $11.8 million, and became effective January 2021.

Conservation and Energy ~~Efficiency (“CEE”).~~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, Southwest made its~~ 2019 ARA filing, ~~which~~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 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, and rates became effective January 2020. In its May 2020 ARA filing, Southwest proposed annualized margin decreases of $313,000 and $55,000 for southern and northern Nevada, respectively, which were approved and became effective January 2021.

Expansion and Economic Development Legislation. In January 2016, final regulations were approved by the PUCN associated with legislation (“SB 151”) previously introduced and signed into law in Nevada. The legislation authorized natural gas utilities

to expand their infrastructure to provide service to unserved and underserved areas in Nevada.

In November 2017, Southwest filed for preapproval of a project to extend service to Mesquite, Nevada, in accordance with the SB 151 regulations. Ultimately, the PUCN issued an order approving Southwest’s proposal ~~to expand natural gas infrastructure to Mesquite.~~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.

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 the distribution system from the interior backbone system. The total capital investment iswas estimated to 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. ~~Initial ground-breaking is expected~~Construction of the initial phase of the expansion began in the ~~summer~~third quarter of 2020, and service commenced to the first Spring Creek customers in December 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~~the multi-year project. OfApproximately $59 million of the ~~total~~ estimated $174 million cost of the CDMI ~~approximately $59 million~~ would be allocable to the Nevada rate jurisdictions.

In response to 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 ~~proposed~~was authorized to ~~establish a level~~include CDMI operations and maintenance costs since the beginning of ~~expense of approximately $1.2 million in rates~~the test year as part of its ~~pending general rate case filing.~~revenue requirement in the case. The customer service system portion of the project was placed in service in May 2021, and the gas transaction system portion is expected to ~~be moved to production~~follow later in 2021.

Regulatory Asset Related to COVID-19.

These costs will be considered by the PUCN for future recovery.

FERC Jurisdiction

General Rate Case. Paiute Pipeline Company (“Paiute”), a wholly owned subsidiary of Southwest, filed a general rate case with the FERC in May 2019. The filing fulfilled an obligation from the settlement agreement reached in the 2014 Paiute general rate case. ~~The application requested an increase in operating revenues of approximately $7 million, and included the continuation of term-differentiated rates.~~

In January 2020, ~~Paiute~~Paiute reached an agreement in principle with the FERC Staff and intervenors to settle its most recent general rate case. In addition to continuing the term-differentiated rate structures with its shippers, the agreement requires Paiute’s three largest transportation customers and all of its storage customers to extend their service agreements to have primary terms of at least five years. The settlement ~~which was filed in March 2020, would result~~resulted in a revenue reduction of approximately ~~$700,000. The agreement-in-principle~~$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 authority to place the settlement rates into effect on an interim basis, effective February 2020. These rates will remain in effect, subject to final FERC approval. Should the proceeding not be resolved by the agreement in principle, or if the settlement proceeds as a contested settlement, Paiute is authorized to receive the difference between the interim settlement rates and the separately filed motion rates from affected customers, retroactive to February 2020. On March 30, 2020, Paiute filed athe proposed settlement agreement with the FERC for review and ~~approval, which is expected later this year.~~approval. On July 6, 2020, the FERC issued a letter order approving the settlement, and the order became final on August 5, 2020.

PGA Filings

The rate schedules in all of Southwest’s service territories contain provisions that permit 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. Balances are recovered from or refunded to customers on an ongoing basis with interest. As of March 31, ~~2020, over-collections~~2021, under-collections in each of Southwest’s service territories resulted in ~~a liability~~an asset of ~~$26.5~~$238.9 million on the Company’s and Southwest’s 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).

Capital Resources and Liquidity

Historically, cash on hand and cash flows from operations have provided a substantial portion of cash used in investing activities (primarily for construction expenditures and property additions). In recent years, ~~the Company~~Southwest has ~~accelerated~~undertaken significant pipe replacement activities to fortify system integrity and reliability, ~~notably~~including on an accelerated basis in association with certain gas infrastructure replacement ~~programs as discussed previously.~~programs. This accelerated activity has necessitated the issuance of both debt and equity securities to supplement cash flows from operations. The Company endeavors to maintain an appropriate balance of equity and debt to ~~maintain strong~~preserve investment-grade credit ratings, which should minimize interest costs.

Financing Cash Flows. Net cash ~~used in~~provided by financing activities increased ~~$109~~$304 million in the first three months of ~~2020~~2021 as compared to the same period of ~~2019.~~2020. The increase was primarily due to ~~payments~~Southwest’s $250 million Term Loan issued in the ~~current period~~first quarter of 2021 to fund the increased cost of natural gas supply noted above related to the extreme cold weather event. Additionally, in the prior-year period, Southwest had more repayment activity for the portion of ~~Southwest’s~~its revolving credit facility that is designated for working capital ~~purposes, offset by an increase in capital contributions from Southwest Gas Holdings, Inc.~~purposes. See Note 5 – Debt.

Gas Segment Construction Expenditures and Financing

During the twelve-month period ended March 31, ~~2020,~~2021, construction expenditures for the natural gas operations segment were ~~$788 million.~~$647 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 $456 million during this time, and provided approximately 52% of construction expenditures and dividend requirements.~~

Management estimates natural gas segment construction expenditures during the three-year period ending December 31, ~~2022~~2023 will be approximately ~~$2.1 billion.~~$2.1 billion. Of this amount, approximately ~~$650~~$700 million ~~to $700 million~~ is scheduled to be incurred in ~~2020.~~2021. Southwest plans to continue to request regulatory support ~~as necessary and appropriate~~to undertake projects, or to accelerate projects ~~that improve~~as necessary, for the improvement of system flexibility and reliability, ~~(including replacement of early vintage plastic and steel pipe).~~or to expand, where relevant, to unserved or underserved areas. Southwest may expand existing, or initiate new, programs. Significant replacement activities are ~~currently~~ expected to continue well beyond the next few years. See also Rates and Regulatory Proceedings ~~for discussion of Nevada infrastructure, Arizona COYL and VSP programs, and Spring Creek in Nevada.~~. During the three-year period, cash flows from operating activities of Southwest are expected to provide approximately 50% of the funding for gas operations and total construction expenditures and dividend requirements. Any additional cash requirements, including construction-related and paydown or refinancing of debt, 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,~~of surcharge collections from, or amounts returned to, customers related to other regulatory mechanisms and programs, 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.

Bonus Depreciation

In 2017, with the enactment of U.S. tax reform, the bonus depreciation deduction percentage changed from 50% to 100% for “qualified property” placed in service after September 27, 2017 and before 2023. The bonus depreciation tax deduction phases out starting in 2023, by 20% for each of the five following years. Qualified property excludes most public utility property. The

Company estimates bonus depreciation will defer the payment of approximately ~~$10~~$20 million of federal income taxes for ~~2020,~~2021, none of which relates to ~~utility~~natural gas operations.

Dividend Policy

Dividends are payable on the Company’s common stock at the discretion of the Board of Directors (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, 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 ~~2020,~~2021, the Board elected to increase the quarterly dividend from ~~$0.545~~$0.57 to ~~$0.570~~$0.595 per share, representing a ~~4.6%~~4.4% increase, effective with the June ~~2020~~2021 payment.

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. Natural 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 the service of our customers. The Company will continuously review and assess the ongoing impacts of the COVID-19 pandemic, including those on our customers, suppliers, and business. As of March 31, 2020, the Company’s Cash and cash equivalents were $61 million, and the Company had access to $454 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 March 31, ~~2020,~~2021, the combined balance in the PGA accounts totaled an ~~over-collection~~under-collection of ~~$26~~$239 million. ~~See~~See PGA Filings for more information.

In March 2021, Southwest issued a $250 million Term Loan that will mature in March 2022, or 364 days after issuance. The proceeds were used to fund the increased cost of natural gas supply during the month of February 2021 caused by extreme weather conditions in the central U.S.

Southwest Gas Holdings, Inc. has a credit facility with a borrowing capacity of $100 ~~million; on~~million that expires in April ~~10, 2020, the existing credit~~2025. This facility ~~was amended to extend the maturity date to April 10, 2025, while maintaining the borrowing capacity at $100 million. The Company intends to utilize this facility~~is intended for short-term financing needs. At March 31, ~~2020, $60~~2021, $43 million was outstanding under this facility.

Southwest has a credit facility, with a borrowing capacity of $400 ~~million; on~~million, which expires in April ~~10, 2020,~~2025. Southwest amended the credit facility agreement which extended the maturity date to April 10, 2025. The revolving borrowing capacity under the amended credit facility agreement remains at $400 million. Southwest designateddesignates $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~~the credit facility (including a commercial paper program, as noted below) during the first three months of ~~2020~~2021 was $150 million, the same amount which was outstanding as of March 31, ~~2020. Additionally, the~~2021. The maximum amount outstanding on the short-term portion of the credit facility during the first ~~three months~~quarter of ~~2020~~2021 was ~~$194~~$125 million. As of March 31, ~~2020, $97~~2021, $17 million ~~of borrowings were~~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. ItThe credit facility 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~~2021 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 March 31, ~~2020,~~2021, there ~~were no borrowings~~was $50 million outstanding under this program.

Centuri has a senior secured revolving credit and term loan facility with borrowing capacity of $590 million (refer to Note 5 – Debt). The line of credit portion ~~of the facility is~~comprises $325 million; associated amounts borrowed and repaid ~~under the revolving credit facility~~ are available to be re-borrowed. The term loan facility portion has a limit of approximately $265 million. The $590 million credit and term loan facility expires in November ~~30,~~ 2023. It 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 assets securing the facility at March 31, ~~2020 totaled $1.2~~2021 totaled $1.3 billion. ~~The~~The maximum amount outstanding on the combined facility during the first three months of ~~2020~~2021 was ~~$286 million; of~~$249 million, at which ~~$242~~point $223 million was outstanding on the term portion.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

See Item 7A. Quantitative and Qualitative Disclosures about Market Risk in the ~~2019~~2020 Annual Report on Form 10-K filed with the SEC. No material changes have occurred related to the disclosures about market risk.

ITEM 4. CONTROLS AND PROCEDURES

Management of Southwest Gas Holdings, Inc. and Southwest Gas Corporation has established disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-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 March 31, ~~2020~~,2021, management of Southwest Gas Holdings, Inc., including the Chief Executive Officer and Chief Financial Officer, believes the Company’s disclosure controls and procedures are effective at attaining the level of reasonable assurance noted above.

There have been no changes in the Company’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) during the first quarter of ~~2020~~2021 that have materially affected, or are likely to materially affect, the Company’s internal control over financial reporting.

There have been no changes in Southwest’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) during the first quarter of ~~2020~~2021 that have materially affected, or are likely to materially affect Southwest’s internal control over financial reporting.

In May 2021, the Company implemented a new customer service system, which involved replacing the legacy functionality for customer invoicing, customer service administration, and ancillary activities. The customer service system is being deployed for transactions starting in May 2021, and was not utilized in preparing the first quarter 2021 financial information. Management monitored developments related to the customer service system replacement, including working with the project team to ensure control impacts were identified and documented, in order to assist management in evaluating impacts to internal control. System integration and user acceptance testing were conducted to aid management in its evaluations. Post-implementation reviews of the system and impacted business processes are being conducted to enable management to evaluate the design and effectiveness of internal controls.

PART II - OTHER INFORMATION

~~Risk Factor that applies to Southwest Gas Holdings, Inc., Natural Gas Operations, and Utility Infrastructure Services~~

~~The Ongoing COVID-19 Pandemic and Measures Intended to Prevent its Spread Could Have a Material Adverse Effect on our Business, Results of Operations, Cash Flows and Financial Condition.~~

Since being first reported in December 2019, COVID-19 has spread globally, including to every state in the United States. On March 11, 2020, the World Health Organization declared COVID-19 a pandemic, and on March 13, 2020, the United States declared a national emergency with respect to COVID-19. The pandemic has led governments and other authorities around the world, including federal, state and local authorities in the United States, to impose measures intended to control its spread, including restrictions on freedom of movement and business operations such as travel bans, border closings, business closures, quarantines and shelter-in-place orders. Substantially all of our properties are located in areas that are or have been subject to shelter-in-place orders and restrictions on the types of businesses that may continue to operate.

Although our utility operations and, to a large extent, our utility infrastructure services segment have been deemed “essential services,” our business may be materially and adversely impacted by the COVID-19 pandemic and measures to prevent its spread in a number of ways. The COVID-19 pandemic has resulted in significant unemployment, which may impact our customers’ ability to timely pay their bills. We have implemented 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. As a result, we have continued providing services even in scenarios where payment is not guaranteed. Although we may be able to seek recovery of some losses through the regulatory process, we can provide no assurances that we will be able to recover such losses in full or at all. In addition, our supply chain related to necessary equipment and materials may be significantly disrupted if the current crisis continues for an extended period of time.

Furthermore, the COVID-19 pandemic has delayed certain construction projects in our utility infrastructure services segment. We can provide no assurances as to whether future delays will occur or as to the impact of such delays. In addition, there may be disruptions in the amount or timing of work awarded to our utility infrastructure services business. Our ability to perform work for which we are contracted could also be impacted by the pandemic if our workforce experiences significant infection. Any of the foregoing could have an adverse impact on our results of operations and financial condition.

The uncertainties have resulted in significant volatility in securities markets. If these disruptions were to continue, they may prevent us from accessing the equity or debt capital markets on attractive terms or at all for a period of time, which would have an adverse effect on our liquidity position.

The extent of the COVID-19 pandemic’s effect on our operational and financial performance will depend on future developments, including the duration, spread and intensity of the pandemic and the duration of government measures to mitigate the pandemic, all of which are uncertain and difficult to predict. Due to the speed with which the situation is developing, we are not able at this time to estimate the effect of these factors on our business, but the adverse impact on our business, results of operations, financial condition and cash flows could be material.
