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

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. 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, 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 2019 Annual Report to Stockholders, which is incorporated by reference into the 2019 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.
13

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

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:
(Thousands of dollars) June 30, 2020 December 31, 2019
Southwest Gas Corporation:
Net cash surrender value of COLI policies $ 128,659    $ 132,072   
Other property 1,975    1,715   
Total Southwest Gas Corporation 130,634    133,787   
Centuri property, equipment, and intangibles 1,041,528    983,905   
Centuri accumulated provision for depreciation and amortization (384,108)   (352,333)  
Other property 21,057    18,814   
Total Southwest Gas Holdings, Inc. $ 809,111    $ 784,173   
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 of Southwest and the Company include money market fund investments totaling approximately $40,000 for both entities at June 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 three-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 continued COVID-19 pandemic, and as utility service is an essential service to the residents in the states in which Southwest operates, in March 2020, Southwest implemented a temporary moratorium 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 June 30, 2020 reflects the expected impact of COVID-19 on balances as of
14

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

that date, including consideration of customers’ ability to pay currently and once the moratorium is lifted. The allowance was not materially adjusted as a result of the pandemic.
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.
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.
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 $57 million at both June 30, 2020 and 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 June 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 six 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, no impairment was deemed to have occurred.

Other current liabilities for Southwest includes $26.4 million and $25.2 million of dividends declared by Southwest Gas Corporation, but not yet paid to Southwest Gas Holdings, Inc. as of June 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 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 June 30, 2020 is October 2020.
Master netting arrangements exist with each counterparty that provide for the net settlement of all contracts through a single payment. Management has elected to reflect the net amounts in its balance sheets, which were immaterial at June 30, 2020.
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 a market approach that utilizes certain financial metrics from guideline public companies of similar industry and operating characteristics. However, the carrying value was greater than the fair value as of June 30, 2020, and no previous upward redemption value adjustments were made following the acquisition date. SEC guidance indicates that a redemption value adjustment would not be made under these circumstances. The following depicts the change to the balance of the redeemable noncontrolling interest:

Recent Accounting Standards Updates.
Accounting pronouncements adopted in 2020:
In June 2016, the Financial Accounting Standards Board (“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 previously 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. The Company and Southwest have no material implementation costs related to cloud computing arrangements.
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 Income Taxes.” The update simplifies the accounting for income taxes by removing certain exceptions to the general principles, as well as improving consistent application in Topic 740 by clarifying and amending existing guidance. The update is effective for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. Early adoption is permitted for periods for which financial statements have not yet been made available for issuance. Management is evaluating the impacts this update might have on the Company’s and Southwest’s consolidated financial statements and disclosures.
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. The update applies only to contracts and hedging relationships that reference London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued due to reference rate reform. The expedients and exceptions provided by the amendments do not apply to contract modifications made or entered into after December 31, 2022. Management is evaluating the impacts this update might have on the Company’s and Southwest’s consolidated financial statements and disclosures. See also LIBOR discussion in Note 5 – Debt.

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 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, 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 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 June 30, 2020 and December 31, 2019 on the Company’s Condensed Consolidated Balance Sheets:
(Thousands of dollars) June 30, 2020 December 31, 2019
Contracts receivable, net $ 240,917    $ 223,904   
Revenue earned on contracts in progress in excess of billings 145,414    99,399   
Amounts billed in excess of revenue earned on contracts 6,633    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 June 30, 2020 is due to revenue recognized of $4.5 million that 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 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 June 30, 2020, Centuri had 26 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 June 30, 2020 was $60.1 million. Centuri expects to recognize the remaining performance obligations over approximately the next two years; 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:
(Thousands of dollars) June 30, 2020 December 31, 2019
Billed on completed contracts and contracts in progress $ 235,971    $ 216,268

Note 5 – Debt
Long-Term Debt
Long-term debt is recognized in the Company’s and Southwest’s Condensed Consolidated Balance Sheets generally at the carrying value of the obligations outstanding. However, details surrounding the fair value and individual carrying values of instruments are discussed below or provided in the table that follows.
The fair values of Southwest’s revolving credit facility (including commercial paper) and the variable-rate Industrial Development Revenue Bonds (“IDRBs”) approximate their carrying values. The fair values of the 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 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 are categorized as Level 2. 
The Centuri secured revolving credit and term loan facility and Centuri’s other debt obligations (not actively traded) are categorized as Level 3. Because Centuri’s debt is not publicly traded, fair values for its secured revolving credit and term loan facility and other debt obligations were based on a conventional discounted cash flow methodology 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.

Southwest has a $400 million credit facility, for which it has designated $150 million of associated capacity as long-term debt and the remaining $250 million, for working capital purposes. Interest rates for the credit facility are calculated at either the LIBOR or an “alternate base rate,” plus in each case an applicable margin that is determined based on Southwest’s senior unsecured debt rating. At June 30, 2020, the applicable margin is 1% for loans bearing interest with reference to LIBOR and

0% for loans bearing interest with reference to the alternative base rate. At June 30, 2020, there were no outstanding amounts on the long-term portion of the facility.
On April 10, 2020, Southwest amended its credit facility agreement; total borrowing capacity under the amended agreement remains $400 million. The amended agreement extended the maturity date from March 2022 to April 2025. Under the amended agreement, the applicable margin will range 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 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 June 30, 2020, no borrowings were outstanding under 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 June 2030. A portion of the net proceeds was used to reduce borrowings under Southwest’s credit facility. Additionally, Southwest intends to use a portion of the net proceeds from the issuance of the 2.20% Senior Notes to redeem the 4.45% $125 million Notes due in December 2020. On July 31, 2020, Southwest provided notice to the holders of the 4.45% Notes of Southwest’s intention to redeem the notes in full on September 1, 2020 at a redemption price of 100% plus accrued and unpaid interest.
Centuri has a $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 June 30, 2020 totaled $1.3 billion. At June 30, 2020, $298 million in borrowings were outstanding under Centuri’s combined secured revolving credit and term loan facility. Centuri also received proceeds of $70 million in equipment loans in 2020, 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 primarily used for short-term financing needs. There was $58 million outstanding under this credit facility as of June 30, 2020.
On April 10, 2020, Southwest Gas Holdings, Inc. amended its existing credit facility, extending the maturity date to April 2025. The revolving borrowing capacity under the amended agreement remains at $100 million. Interest rates for the amended facility are calculated at either LIBOR or an “alternate base rate,” plus in each case an applicable margin that is determined based on Southwest Gas Holdings, Inc.’s senior unsecured long-term debt rating. The applicable margin under the amended agreement 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 the 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 Gas Holdings, Inc. may amend the credit facility agreement with a replacement rate, as set forth in the amended agreement. Southwest Gas Holdings, Inc. 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 Gas Holdings, Inc. 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.
As discussed previously, under Southwest’s $400 million credit facility, $250 million has been designated by management for working capital purposes. Southwest had no short-term borrowings outstanding at June 30, 2020 under this facility.

LIBOR
It is currently anticipated that LIBOR may be discontinued as a benchmark or reference rate after 2021. As of June 30, 2020, $58 million and $188 million, respectively, for the holding company and Centuri, was outstanding under credit facilities whereby interest was with reference to LIBOR and for which maturity dates extend beyond 2021; no such borrowings were outstanding for Southwest. As of June 30, 2020, these LIBOR-based borrowings approximately 9% 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.

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 June 30, 2020, Southwest had 2,102,000 residential, commercial, industrial, and other natural gas customers, of which 1,121,000 customers were located in Arizona, 781,000 in Nevada, and 200,000 in California. Over the past twelve months, first time meter sets were approximately 36,000, compared to 33,000 for the twelve months ending June 2019. The remaining increase in active customer accounts compared to the June 30, 2019 total of 2,061,000 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 temporary moratorium in March 2020 and also ceased charging late fees until further notice. We can provide no assurances as to when the moratorium will be lifted. Residential and small commercial customers represented over 99% of the total customer base. During the twelve months ended June 30, 2020, 53% of 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. While these general patterns are expected to remain materially consistent for the 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 a non-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 a dollar-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, and both a decision and new rate establishment are expected to occur 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.
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. Centuri operates in 54 primary locations across 40 states and provinces in the United States (“U.S.”) and Canada. Centuri operates in the U.S. primarily as NPL, Neuco, and Linetec, and in Canada primarily as NPL Canada.

Utility infrastructure services activity can be impacted by changes in infrastructure replacement programs of utilities, weather, and local and federal regulation (including tax rates and incentives). During the past few years, utilities have implemented or modified system integrity management programs to enhance safety pursuant to federal and state mandates. These programs have resulted in a significant increase following those mandates in multi-year 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. 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. Certain jurisdictions have begun re-opening only to return to further restrictions in the face of new COVID-19 cases. 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 are considered an essential service and Southwest continues to provide services to meet the demand of its customers, even while many other types of businesses were or are closed. Consistent with federal and state guidelines, 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, 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 temporary moratorium on natural gas disconnections for non-payment; it is working with customers who are experiencing financial hardship through flexible payment arrangements; and it also ceased charging late fees until further notice. Management does not expect a material increase to the allowance for uncollectibles from such measures as during warmer months, such as the summer season, monthly utility bills for natural gas are substantially reduced. Should the pandemic continue into the winter season, the potential impact could be more significant. 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 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. 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 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 certain of Southwest’s regulatory commissions have implemented measures to 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 $3.4 million of wage subsidies 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, or continued deferment by government officials related to, the resumption of commerce across the service territories of all our businesses, the magnitude of further spread of the virus in advance of and following such resumption, impacts of these conditions on our customers, the state of the North American economy following that resumption, 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 current level of uncertainty over the economic and operational impacts of COVID-19 means the related financial impact cannot be fully estimated at this time, and management cannot predict whether future periods will be impacted differently than the impacts reflected in the six months ended June 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 June 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 2019 Annual Report to Shareholders, which is incorporated by reference into the 2019 Form 10-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 MD&A. As reflected in the table below, the natural gas operations segment accounted for an average of 75% of twelve-month-to-date consolidated net income over the past two years. As such, 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.

$ 11,942    $ 3,369   
Contribution from natural gas operations to consolidated net income increased $8.6 million between the second quarters of 2020 and 2019. The increase was primarily due to an increase in Other income, customer growth, and lower Operations and maintenance expense, offset by an increase in Depreciation and amortization.
Operating margin increased $1.4 million. Customer growth provided approximately $2.5 million of incremental margin from 36,000 first-time meter sets during the last twelve months. Rate relief contributed approximately $400,000 in incremental operating margin. Offsetting the increase were other items, including the impact of the temporary moratorium on late fees and lower connection/re-connection charges during the COVID-19 pandemic.
Operations and maintenance expense decreased $5.7 million between quarters primarily due to the impacts of COVID-19 on training and travel costs and reductions in other service and maintenance costs. Overall, the variance between 2019 and 2020 is expected to narrow in the second half of 2020.
Depreciation and amortization expense increased $3.9 million, or 8%, between quarters, primarily due to a $684 million, or 9%, increase in average gas plant in service compared to the corresponding quarter a year ago, offset by a decrease in regulatory account amortization. The increase in gas plant was attributable to pipeline capacity reinforcement work, franchise requirements, scheduled pipe replacement activities, and new infrastructure.
Other income improved $6.2 million between quarters primarily due to an increase in income from company-owned life insurance (“COLI”) policies. The current quarter reflects a $12 million increase in COLI policy cash surrender values, while the prior-year quarter reflected a $3.4 million increase in COLI policy cash surrender values. These values are significantly impacted by fluctuations in the values of equity securities associated with the cash surrender values, and values in both periods were impacted directionally consistent with the broader securities markets. Offsetting these impacts were higher non-service-related costs associated with employee pension and other postretirement benefits and lower interest income on regulatory account balances.

Contribution to consolidated net income
$ 95,541    $ 106,758   
Contribution from natural gas operations to consolidated net income decreased $11.2 million between the first six months of 2020 and 2019. The decline was primarily due to a decrease in Other income and increases in Depreciation and amortization, partially offset by an increase in Operating margin and lower Operations and maintenance expense.
Operating margin increased $15 million, including $8 million attributable to customer growth. Rate relief, primarily in California, contributed an additional $1 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. The remaining increase primarily resulted from the net recovery of regulatory program balances (collectively, having an offsetting impact in amortization expense), in addition to margin from customers outside the decoupling mechanisms, offset by lower late fees and connect/re-connect charges during the current moratorium noted previously.
Operations and maintenance expense decreased $8.1 million, or 4%, 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. Overall, the variance between 2019 and 2020 is expected to narrow in the second half of 2020.
Depreciation and amortization expense increased $11 million, or 10%, between periods primarily due to a $684 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. Regulatory account surcharges, as noted above, also resulted in increases in amortization expense in the current period.
Other income decreased $20.2 million overall between periods. The current period reflects a $3.5 million decline in COLI policy cash surrender values, while the prior-year period reflected $11 million of COLI-related income. The non-service cost components of employee pension and other postretirement benefits costs were $2.5 million higher between periods. Additionally, lower interest on regulatory balances contributed to the decrease between periods.
Net interest deductions increased $2.6 million between periods, primarily due to higher interest associated with the issuance of $300 million of Senior Notes in May 2019 and higher debt balances outstanding in the current period.

Contribution to consolidated net income from natural gas operations decreased $700,000 between the twelve-month periods ended June 2020 and 2019. The decline was primarily due to higher Depreciation and amortization expense, Net interest deductions, and lower Other income, partially offset by an increase in operating margin.
Operating margin increased $40 million between periods. Customer growth provided $13 million, and combined rate relief, primarily in Nevada and California, provided $7 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 resulted from recoveries of regulatory assets (approximately $10 million, offset in amortization expense below), infrastructure replacement mechanisms, and customers outside the decoupling mechanisms.
Operations and maintenance expense increased $6.1 million (or 1%) between periods primarily due to incremental expenditures for pipeline damage prevention programs and higher legal claim-related costs, partially offset by lower training and travel costs due to the current COVID-19 environment.
Depreciation and amortization expense increased $25.4 million, or 13%, between periods primarily due to a $651 million, or 9%, increase in average gas plant in service since the corresponding period in the prior year. Amortization related to regulatory account recoveries increased approximately $10 million between periods.
Other income decreased $7.7 million between the twelve-month periods of 2020 and 2019 primarily due to a decline in COLI policy values. The current period reflects a $2.9 million increase in COLI policy cash surrender values, while the prior year period reflected a $6.5 million increase. Lower interest on regulatory account balances and lower amounts associated with the allowance for equity funds applied to projects during construction also impacted the variance between periods.
Net interest deductions increased $8.9 million between periods primarily due to interest associated with the issuance of $300 million of Senior Notes in May 2019.
The reduction in income taxes between periods reflects lower earnings, as well as 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 $40.5 million in the second quarter of 2020 when compared to the prior-year quarter, due to a higher volume of electric infrastructure and pipe replacement work under blanket and bid contracts. Included in this improvement were revenues of $7.3 million in the second quarter of 2020 from storm-related electric services work that did not occur during the same quarter in the prior year. Centuri achieved the overall increase in revenues despite a temporary shut-down for certain crews 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 $28 million in the second quarter of 2020 when compared to the prior-year quarter, due primarily to costs to complete additional electric infrastructure and pipe replacement work, partially offset by increased productivity and efficiencies on electrical infrastructure projects and lower fuel and overtime costs. Additionally, Centuri’s mix of work was favorably impacted by certain restrictions on service-line related work due to COVID-19, which allowed for an increase in main line replacement work, and resulted in greater production efficiency and reduced travel time. Centuri also benefited from $3.4 million in wage subsidies from the Canadian government amidst the COVID-19 environment. These funds were recorded as a reduction in wage-related expenses, included within this line item. Offsetting some of these improvements were certain increased costs and workforce inefficiencies associated with the continued impact of the COVID-19 pandemic.
Depreciation and amortization expense increased $3 million between quarters attributable to additional equipment purchased to support the growing volume of work being performed, primarily at Linetec.
Net interest deductions decreased $1.2 million between periods due primarily to lower rates associated with outstanding borrowings under the $590 million secured revolving credit and term loan facility.

Utility infrastructure services revenues increased $61.1 million during the first six months of 2020 when compared to the same period in the prior year due to a higher volume of electric infrastructure and pipe replacement work under blanket and bid contracts. Electric infrastructure work composed $53.9 million of that increase, including the storm-related work noted earlier. The improvement was achieved despite a temporary shut-down for certain crews in response to local government requirements to postpone non-essential business services and precautions to ensure employee safety during the COVID-19 outbreak. Results during the first six months of 2019 reflected incremental profit from customer requested strike support that did not recur in 2020.
Utility infrastructure services expenses increased $46.9 million during the first six months of 2020 when compared to the same period in the prior year, due primarily to increased costs to complete additional electric infrastructure and pipe replacement work, partially offset by the increased productivity and efficiencies on electrical infrastructure projects and lower fuel and overtime costs noted for the second quarter of 2020. Additionally, the improved mix of work during the second quarter for main line replacements provided cost efficiencies. Offsetting these favorable impacts were certain increased costs and workforce inefficiencies associated with the continued impact of the COVID-19 pandemic.
Depreciation and amortization expense increased $6 million between periods attributable to additional equipment purchased to support the growing volume of work being performed, primarily at Linetec.
Net interest deductions were lower during 2020 due to lower rates associated with outstanding borrowings under the $590 million secured revolving credit and term loan facility.

Net income attributable to noncontrolling interest 3,739 1,523   
Contribution to consolidated net income attributable to Centuri $ 57,581    $ 47,629   
Utility infrastructure services revenues increased $177.9 million overall in the current twelve-month period compared to the corresponding period of 2019, primarily due to incremental revenues from Linetec (acquired in November 2018) of $165.5 million, as well as continued growth with existing customers under master service and bid agreements. Partially offsetting these increases were decreased revenues from certain non-routine or non-recurring 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 professional engineering stamp 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 increased $141.4 million between periods, primarily due to incremental expenses related to Linetec of $137.7 million, along with additional electric infrastructure and pipe replacement work and higher labor-related operating expenses to support growth. Included in total Utility infrastructure services expenses were general and administrative costs, which increased $2 million in the twelve-month period ended June 2020 when compared to the corresponding period ended June 2019. Offsetting impacts include deal costs from the acquisition of Linetec during 2018 ($6.9 million). Net gains on sale of equipment (reflected as an offset to Utility infrastructure services expenses) were $4.9 million and $2.3 million for the twelve-month periods of 2020 and 2019, respectively.
Depreciation and amortization expense increased $21.5 million between the current and prior-year period. The increase was primarily attributable to the incremental assets related to the acquisition of Linetec, providing $15.5 million of the increase in this category. Depreciation on additional property and equipment purchased to support the growing volume of work being performed composes the remainder of the increase.
Net interest deductions decreased $1.9 million between periods due primarily to lower rates associated with outstanding borrowings under the $590 million secured revolving credit and term loan facility.

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 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 LNG facility discussed below. The application also includes a proposed 10.3% return on equity (“ROE”) relative to a capital structure of 51.1% equity. At the time of the filing, the Company estimated the return of approximately $20.6 million of excess accumulated 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 accumulated excess deferred income taxes known after the Company’s 2018 federal income tax return was filed in 2019. It was at such point that the actual amount could be computed based on the prescribed methodology for determining the amount that could be returned 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 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 request overall 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. A hearing in this matter was previously scheduled for April 2020; however, due to the COVID-19 pandemic, the hearing was conducted during 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 changes in the amortization of excess accumulated deferred income taxes (“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. Legal briefs will continue through 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. 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, 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 ultimately elected to reduce the rate to zero in an effort to provide some measure of customer relief in light of current issues related to the COVID-19 pandemic, and at the time of both the April filing and the ACC decision, the 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 2018, Southwest filed an application with the ACC, 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 $1.6 million as of June 30, 2020.
Liquefied Natural Gas (“LNG”) Facility. In January 2014, Southwest filed an application with the 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, to be operated by Southwest, and connected directly to its distribution system. Southwest was ultimately granted approval for construction and deferral of costs not to exceed $80 million. Construction began during the third quarter of 2017 and the facility was placed in service in December 2019. Southwest incurred approximately $75.3 million in capital expenditures toward the project (including land acquisition costs), which are considered as part of Southwest’s pending rate case. In addition to tracking the revenue requirement associated with the capital investment in a regulatory asset, operating expenses associated with the plant are also authorized to be included in a regulatory asset, which is also being addressed as part of the pending general rate case.
Customer-Owned Yard Line (“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. “Phase II” of the COYL program included the replacement of non-leaking COYLs. The surcharge is designed to collect the annual revenue requirement as the program progresses. In the filing made in February 2019, 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 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 review an estimated $21.1 million of 2019 COYL 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 plant adjustment, with inclusion of related amounts in base rates, and also support the continuation of the COYL program.
Vintage Steel Pipe (“VSP”) Program. Southwest received approval, in connection with its 2016 Arizona general rate case, to implement a VSP replacement program. Southwest currently has a substantial amount of pre-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. A surcharge related thereto has been customarily designed to be revised annually as the program 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) related to 2018 expenditures. Southwest replaced 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 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 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 hearing in this matter was held in June 2020. Legal briefs will continue through 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 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 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 overall. 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 excess accumulated deferred income taxes 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%, 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 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 the proposed risk-informed decision making proposals, which consist of a 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 early August 2020, and if approved, new rates would be expected to become effective in January 2021.
Attrition Filing. In November 2019, Southwest made its latest annual PTY attrition filing, requesting annual revenue increases of $2.06 million in southern California, $556,000 in northern California, and $278,000 for South Lake Tahoe. This filing was approved in December 2019 and rates were made effective in January 2020. At the same time, rates were 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 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. 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 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 cost for the
44

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

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 a 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 Application for Authority to Implement the CDMI. The CPUC issued a final decision approving the settlement agreement as filed in July 2020.
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. Southwest filed a general rate case application with the PUCN on February 28, 2020, which requested a statewide overall general rate increase of approximately $38.3 million. The request seeks an ROE of 10% relative to a proposed capital structure of 50% equity and continuation of the General Revenues Adjustment (“GRA”) mechanism (full revenue decoupling). The request also proposes the recovery of previously excluded costs attributable to several software applications. On June 26, 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 on July 24, 2020, recommending an overall increase of approximately $21.6 million and approximately $20 million, respectively. A substantial portion of the difference between Southwest’s request and the proposals of these parties relates to differences in the recommended ROE. No party contested the recovery of the remaining balances of the previously excluded software applications or the continuation of the GRA. Included in the Commission’s Staff recommended increase is approximately $585,000 related to incremental operation and maintenance expenses related to Southwest’s CDMI (discussed below), providing an opportunity for recovery of these costs following the denial of Southwest’s request for deferred accounting treatment in 2019. A hearing in this matter is scheduled for August 2020.
In December 2018, the PUCN issued a rate case decision in the previous general rate case application, which authorized a ROE of 9.25% relative to the Company’s proposed capital structure of 49.66% equity applicable to both southern and northern Nevada and provided for an overall revenue increase of $9.5 million in southern Nevada and a revenue decrease in northern Nevada of $2 million. Rates from this proceeding originally became effective in January 2019.
As part of that proceeding, management filed a request for reconsideration of several rate case issues during the same month of effective rates, and the PUCN Staff also filed for reconsideration, related to technical clarifications on the calculation of the intended results of the decision. The PUCN issued a decision regarding both petitions in February 2019 that modified certain parts of the original order, but 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 an increase in operating income of $7.9 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, Southwest filed an appeal with the Nevada Supreme Court, the resolution of which will likely take 12-24 months. Southwest expects consideration of the appeal to occur concurrently with the proceedings of the 2020 general rate case, a decision which is currently pending.
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 general rate case application filed in February 2020. In June 2019, Southwest made its 2019 Annual Rate Adjustment (“ARA”) filing in which it requested to update the GRA to reflect the current balances in both southern and northern Nevada. This 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. While there is no impact to net income overall from adjustments to recovery
45

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

rates associated with the related regulatory balances, operating cash flows are impacted by such changes. In May 2020, Southwest made its 2020 ARA filing, which proposes annualized margin decreases of $5.3 million in southern Nevada and an increase of $1.6 million in northern Nevada.
Infrastructure Replacement Mechanism. In 2014, the PUCN approved final rules for the Gas Infrastructure Replacement (“GIR”) mechanism which defers and recovers 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 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 to reset the recovery surcharge to 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 of approximately $5.3 million in southern Nevada and no incremental revenue in northern Nevada
Conservation and Energy Efficiency (“CEE”). 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 June 2019, Southwest made its 2019 ARA filing, which 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 May 2020, Southwest made its 2020 ARA filing which proposes annualized margin decreases of $313,000 and $55,000 for southern and northern Nevada, respectively.
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 and service to Mesquite. 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 was implemented October 1, 2019 to recover the cost and is applicable to all southern Nevada customers (including new customers in Mesquite). In May 2020, Southwest made its 2020 ARA filing, which proposes an annualized margin increase of $185,000, which reflects the cumulative deferred revenue requirement associated with the Mesquite facilities that have been placed in service through April 30, 2020. Following preliminary design, in February 2019, Southwest began serving certain customers with an approved virtual pipeline network, providing temporary natural gas supply using portions of the approved distribution system and compressed natural gas. It is estimated that construction of the remaining approved distribution system to bring the permanent supply to Mesquite will be placed in service in the first quarter of 2021.
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 the distribution system from the interior backbone system. The total capital investment is 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 in the summer 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 the CDMI would be allocable to the Nevada rate jurisdictions. A hearing on this 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 the most appropriate venue to address such costs. In response to the PUCN’s decision, Southwest filed a Petition for Reconsideration in October 2019, which was denied. Southwest proposed to establish a level of expense of approximately $1.2 million in rates as part of its pending general rate case
46

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

filing. The project is expected to be moved to production in 2021. As described above, Southwest has a proposal to provide an opportunity to recover these costs as part of its pending rate case.
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 Governor Steve Sisolak declared a state of emergency 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. 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 customers and all of its storage customers to extend their service agreements to have primary terms of at least five years. The settlement will result 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 authority to place the settlement rates into effect on an interim basis effective February 2020. On March 30, 2020, Paiute filed the proposed settlement agreement with the FERC for review and approval. On July 6, 2020, the FERC issued a letter order approving the settlement. If no party requests rehearing within 30 days, the order will become 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. As of June 30, 2020, over-collections in each of Southwest’s service territories resulted in a liability of $69.9 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 has accelerated pipe replacement activities to fortify system integrity and reliability, notably in association with gas infrastructure replacement programs as discussed previously. 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 investment-grade credit ratings, which should minimize interest costs.
Cash Flows
Southwest Gas Holdings, Inc.:
Operating Cash Flows. Cash flows provided by consolidated operating activities increased $97 million in the first six months of 2020 as compared to the same period of 2019. The 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

collections ($39 million) related to the Arizona decoupling mechanism balance between six-month periods, as well as increases from other working capital components. 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). Customarily, differences between amounts Southwest pays to gas suppliers and amount included in customer rates to recover the cost of purchased gas under the purchased gas cost mechanisms has provided significant variability in operating cash flows between periods.
Investing Cash Flows. Cash used in consolidated investing activities decreased $66 million in the first six months of 2020 as compared to the same period of 2019. The change was primarily due to a decrease in capital expenditures in both reportable segments in the first six months of 2020. Additionally, the prior-year period included $19.5 million for the remittance of purchase consideration previously held back in association with the 2018 Linetec acquisition.
Financing Cash Flows. Net cash provided by consolidated financing activities increased $35 million in the first six months of 2020 as compared to the same period of 2019. The change was primarily due to net proceeds of $447 million (after discount and fees) from the issuance of $450 million Senior Notes in June 2020 by Southwest, in which the funds were partially used to reduce the amounts then outstanding under its credit facility ($309 million); and 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. Additionally, there was a decrease ($48 million) in issuances of common stock under the Company’s Equity Shelf Program in the first half of 2020 compared to issuances under programs in the prior-year period. See Note 4 – Common Stock and Note 5 – Debt. Other outflows include the combined impacts of repayment and borrowings by Centuri under its secured credit and revolving credit facility, offset by $70 million in equipment loan proceeds.
During the six months ended June 30, 2020, the Company issued 86,000 shares of common stock through the Dividend Reinvestment and Stock Purchase Plan, raising approximately $6 million, similar to amounts raised in the prior year period.
The capital requirements and resources of the Company generally are determined independently for the natural gas operations and utility infrastructure services segments. Each business activity is generally responsible for securing its own external debt financing sources. However, the holding company may raise funds through stock issuance or other external financing sources. See Note 4 – Common Stock.
Southwest Gas Corporation:
Operating Cash Flows. Cash flows provided by operating activities increased $92 million in the first six 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 $6 million in the first six 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.
Financing Cash Flows. Net cash provided by financing activities increased $53 million in the first six months of 2020 as compared to the same period of 2019. The increase was primarily due to the issuance of $450 million Senior Notes in the current period, net of amounts used to reduce the amounts outstanding under Southwest’s credit facility, compared to the prior year $300 million Senior Notes issuance and related credit facility and commercial paper program repayments. See Note 5 – Debt. The combined impact of dividends and contributions to/from the parent holding company resulted in a reduction in financing cash flows.
Gas Segment Construction Expenditures and Financing
During the twelve-month period ended June 30, 2020, construction expenditures for the natural gas operations segment were $768 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 $460 million during this time, and provided approximately 53% of construction expenditures and dividend requirements.
Management estimates natural gas segment construction expenditures during the three-year period ending December 31, 2022 will be approximately $2.1 billion. Of this amount, approximately $700 million is scheduled to be incurred in 2020. Southwest plans to continue to request regulatory support as necessary and appropriate to accelerate projects that improve system flexibility and reliability. 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 total

construction expenditures and dividend requirements. 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 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. Additionally, Southwest intends to use a portion of the net proceeds from the issuance to redeem the 4.45% Notes. On July 31, 2020, holders of the 4.45% Notes due in December 2020 were notified of Southwest’s intention to redeem the notes in full on September 1, 2020 at a redemption price of 100% plus accrued and unpaid interest.
In May 2019, the Company filed with the SEC an automatic shelf registration statement for the offer and sale of up to $300 million of common stock from time to time in at-the-market offerings under the prospectus included therein in accordance with the Sales Agency Agreement, dated May 8, 2019, between the Company and BNY Mellon Capital Markets, LLC (the “Equity Shelf Program”). The Company issued $50 million under this multi-year program during the second quarter of 2020; approximately $126 million is available under the program as of June 30, 2020. Net proceeds from the sales of shares of common stock under the Equity Shelf Program are intended for general corporate purposes, including the acquisition of property for the construction, completion, extension or improvement of pipeline systems and facilities located in and around the communities served by Southwest.
During the twelve months ended June 30, 2020, 1,325,796 shares were issued in at-the-market offerings at an average price of $74.93 per share with gross proceeds of $99.3 million, agent commissions of $993,000, and net proceeds of $98.3 million under the Company’s Equity Shelf Program.
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 million of federal income taxes for 2020, none of which relates to utility 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. In February 2020, the Board elected to increase the quarterly dividend from $0.545 to $0.570 per share, representing a 4.6% increase, effective with the June 2020 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 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, 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 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 June 30, 2020, the Company’s Cash and cash equivalents were $200 million (which is intended to redeem Southwest’s $125 million 4.45% Notes on September 1, 2020), and the Company had access to $679 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 June 30, 2020, the combined balance in the PGA accounts totaled an over-collection of $70 million. See PGA Filings for more information.
Southwest Gas Holdings, Inc. has a credit facility with a borrowing capacity of $100 million; on April 10, 2020, the existing credit 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 for short-term financing needs. At June 30, 2020, $58 million was outstanding under this facility.
Southwest has a credit facility, with a borrowing capacity of $400 million; on April 10, 2020, 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 following that amendment. Southwest 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 six months of 2020 was $150 million. As of June 30, 2020, no amount was outstanding under the long-term portion of the facility. Additionally, the maximum amount outstanding on the short-term portion of the credit facility during the first six months of 2020 was $161 million. As of June 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. 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 June 30, 2020, there were no borrowings 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 $325 million; 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 June 30, 2020 totaled $1.3 billion. The maximum amount outstanding on the facility during the first six months of 2020 was $312 million, of which $235 million was outstanding on the term portion. As of June 30, 2020, $77 million was outstanding on the revolving credit facility and $231 million was outstanding on the term loan portion of the facility. Also at June 30, 2020, there was approximately $237 million, net of letters of credit, available under the line of credit.
On April 10, 2020, the holding company and Southwest amended their respective credit facility agreements (see above). Interest rates for the amended credit facilities are calculated at either LIBOR or an “alternate base rate,” plus in each case an applicable margin that is 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 June 30, 2020, $58 million borrowings were outstanding for the holding company under its credit facility (see Note 5 – Debt), and $188 million of Centuri’s indebtedness under its facility have interest rates with reference to LIBOR and maturity dates that extend beyond 2021. Southwest had no borrowings outstanding under its amended credit facility as of June 30, 2020. The above amounts that were outstanding for the holding company and for Centuri reflect approximately 9% of total debt (including current maturities) for the Company 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 impact a LIBOR discontinuation will have on their financial condition or results of operations. Any alternative rate may be less predictable or less attractive than LIBOR.

For additional information on the risks associated with the Company’s business, see Item 1A. Risk Factors and Item 7A. Quantitative and Qualitative Disclosures About Market Risk in the Annual Report on Form 10-K for the year ended December 31, 2019, and Item 1A.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
See Item 7A. Quantitative and Qualitative Disclosures about Market Risk in the 2019 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 June 30, 2020, 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 second quarter of 2020 that have materially affected, or are likely to materially affect, the Company’s internal control over financial reporting.
