SOUTHWEST GAS CORPORATION	Form 10-Q
June 30, 2009

Note 1 – Nature of Operations and Basis of Presentation

Nature of Operations. Southwest Gas Corporation and its subsidiaries (the “Company”) are composed of two segments: natural gas operations (“Southwest” or the “natural gas operations” segment) and construction services. Southwest is engaged in the business of purchasing, distributing, and transporting natural gas in portions of Arizona, Nevada, and California. The 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 sales are seasonal, peaking during the winter months; therefore, results of operations for interim periods are not necessarily indicative of the results for a full year. Variability in weather from normal temperatures can materially impact results of operations. Natural gas purchases and the timing of related recoveries can materially impact liquidity. NPL Construction Co. (“NPL” or the “construction services” segment), a wholly owned subsidiary, is a full-service underground piping contractor that provides utility companies with trenching and installation, replacement, and maintenance services for energy distribution systems.

Basis of Presentation. The condensed consolidated financial statements included herein have been prepared by the Company, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to such rules and regulations. 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 revenue and expense 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 presentation of the results for the interim periods, have been made. It is suggested that these condensed consolidated financial statements be read in conjunction with the consolidated financial statements and the notes thereto included in the 2008 Annual Report to Shareholders, which is incorporated by reference into the 2008 Form 10-K, and the first quarter 2009 Form 10-Q.

Intercompany Transactions. NPL recognizes revenues generated from contracts with Southwest (see Note 3 below). Accounts receivable for these services were $4.6 million at June 30, 2009 and $6.6 million at December 31, 2008. The accounts receivable balance, revenues, and associated profits are included in the condensed consolidated financial statements of the Company and were not eliminated during consolidation in accordance with Statement of Financial Accounting Standards (“SFAS”) No. 71,“Accounting for the Effects of Certain Types of Regulation.”

Other Income (Deductions). The following table provides the composition of significant items included in Other income (deductions) on the consolidated statements of income (thousands of dollars):

	Three Months Ended						Six Months Ended						Twelve Months Ended
	June 30,						June 30,						June 30,
	2009			2008			2009			2008			2009			2008

Change in COLI policies	$	3,667		$	(500	)	$	2,073		$	(2,600	)	$	(7,368	)	$	(3,245	)
Interest income		71			981			215			1,781			646			3,313
Miscellaneous income and (expense)		(1,286	)		(1,096	)		(1,540	)		(1,263	)		(3,854	)		(2,303	)

Total other income (deductions)	$	2,452		$	(615	)	$	748		$	(2,082	)	$	(10,576	)	$	(2,235	)

Included in the table above is the change in 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. Current tax regulations provide for tax-free treatment of life insurance (death benefit) proceeds. Therefore, the change in the cash surrender value components of COLI policies as they progress toward the ultimate death benefits are also recorded without tax consequences.

Reclassifications. Certain reclassifications have been made to the prior year’s financial information to present it on a basis comparable with the current year’s presentation. None of the reclassifications affected previously reported net income.

Recently Issued Accounting Pronouncements. In December 2008, the Financial Accounting Standards Board (“FASB”) issued FASB Staff Position (“FSP”) SFAS No. 132(R)-1, “Employers’ Disclosures about Postretirement Benefit Plan Assets” which requires companies to enhance disclosures about the plan assets of a defined benefit pension or other postretirement plan. Companies will be required to disclose how investment decisions are made, the major plan asset categories, the inputs and valuation techniques used to measure the fair value of plan assets, the level within the fair value hierarchy in which the fair value measurements in their entirety fall, the effect of fair value measurements using significant unobservable inputs (Level 3) on changes in plan assets for the period, and significant concentrations of risk within plan assets. The provisions of FSP SFAS No. 132(R)-1 are effective for the Company beginning with 2009 year-end financial statement reports. The Company is evaluating what impact this standard might have on its disclosures.

In June 2009, the FASB issued SFAS No. 166, “Accounting for Transfers of Financial Assets – an amendment of SFAS No. 140” which eliminates the qualifying special purpose entity concept and the related exception from consolidation, limits derecognition of financial assets when control still exists, and requires enhanced disclosures. For the Company, SFAS No. 166 will be effective prospectively for new transfers of financial assets beginning January 2010. The Company is evaluating what impact, if any, this standard might have on its financial position or disclosures.

In June 2009, the FASB issued SFAS No. 167, “Amendments to FASB Interpretation No. 46(R)” which changes the methodology for determining the primary beneficiary of a variable interest entity. This methodology change could cause an entity to consolidate a previously unconsolidated variable interest entity or deconsolidate a previously consolidated variable interest entity if the primary beneficiary has changed under the new guidance. Entities will have the option to adopt retrospectively or through cumulative effect. Enhanced disclosures are also required. The Company currently does not consolidate Southwest Gas Capital II (“Trust II”), a wholly owned subsidiary, which was created as a financing trust for the sole purpose of issuing preferred trust securities for the benefit of the Company. Although the Company owns 100 percent of the common voting securities of Trust II, under Interpretation No. 46 “Consolidation of Variable Interest Entities (revised December 2003)”, the Company is not considered the primary beneficiary and therefore Trust II is not consolidated. SFAS No. 167 will be effective for the Company in January 2010. The Company is evaluating the potential impacts of the standard.

In June 2009, the FASB issued SFAS No. 168 “The FASB Accounting Standards Codification and the Hierarchy of Generally Accepted Accounting Principles—a replacement of FASB Statement No. 162”. The FASB Accounting Standards Codification (“Codification”) will become the source of authoritative U.S. GAAP recognized by the FASB. On the effective date of SFAS No. 168, the Codification will supersede all then-existing non-SEC accounting and reporting standards. All other non-grandfathered non-SEC accounting literature not included in the Codification will become non authoritative. This Statement is effective for financial statements issued for interim and annual periods ending after September 15, 2009. Upon adoption in the third quarter of 2009, any direct references to U.S. GAAP in the Company’s quarterly and annual reports will refer to the Codification or U.S. GAAP, as the Codification is defined, instead of the original accounting pronouncements.

Subsequent Events. Management of the Company monitors significant events occurring after the balance sheet date and prior to the issuance of the financial statements to determine the impacts, if any, of events on the financial statements to be issued. All subsequent events of which management is aware were evaluated through August 4, 2009, the date these financial statements were issued.

Note 7 – Derivatives and Fair Value Measurements

In managing its natural gas supply portfolios, Southwest has historically entered into fixed and variable-price contracts, which qualify as derivatives. In 2008, Southwest also began utilizing 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 provisions. The variable-price contracts have no significant market value. Swaps are subject to the fair value provisions and must be recorded at fair value.

The fixed-price contracts and Swaps are utilized by Southwest under its volatility mitigation programs to effectively fix the price on approximately 50 percent of its natural gas portfolios. The maturities of the Swaps highly correlate to actual purchases of natural gas, during timeframes ranging from July 2009 through October 2010. Under such contracts, Southwest pays the counterparty at a fixed rate and receives from the counterparty a floating rate per MMBtu (“dekatherm”) of natural gas. Only the net differential is actually paid or received. The differential is calculated based on the notional amounts under the contracts (approximately 15.8 million dekatherms at June 30, 2009 and 6.5 million dekatherms at December 31, 2008). Southwest does not utilize derivative financial instruments for speculative purposes, nor does it have trading operations.

The following table sets forth the gains and (losses) recognized on the Company's Swaps (derivatives) for the three months and six months ended June 30, 2009 and their location in the income statement (thousands of dollars):

The estimated fair values of the derivatives were determined using future natural gas index prices (as more fully described below). The Company has master netting arrangements with each counterparty that provide for the net settlement of all contracts through a single payment. As applicable, the Company has elected to reflect the net amounts in its balance sheets.

Pursuant to regulatory deferral accounting treatment for rate-regulated utilities, Southwest records the unrealized gains and losses in fair value of the Swaps as a regulatory asset and/or liability. When the Swaps settle, Southwest reverses any prior positions held and records the settled position as an increase or decrease of purchased gas under the related purchased gas adjustment (“PGA”) mechanism in determining its deferred PGA balances. During the three months and six months ended June 30, 2009, Southwest paid counterparties $2.1 million and $13.7 million, respectively, in settlements of matured Swaps. Neither changes in the fair value of the Swaps nor settled amounts have a direct effect on earnings or other comprehensive income. At June 30, 2009, regulatory assets/liabilities offsetting the amounts in the above table were recorded in Prepaids and other current assets ($8.3 million), Deferred charges and other assets ($281,000), and Other deferred credits ($794,000). At December 31, 2008, regulatory assets/liabilities offsetting the amounts in the above table were recorded in Prepaids and other current assets ($14.4 million) and Other deferred credits ($292,000).

The estimated fair values of Southwest’s Swaps were determined at June 30, 2009 using NYMEX futures settlement prices for delivery of natural gas at Henry Hub adjusted by the price of NYMEX ClearPort basis Swaps, which reflect the difference between the price of natural gas at a given delivery basin and the Henry Hub pricing points. These Level 2 inputs are observable in the marketplace throughout the full term of the Swaps, but have been credit-risk adjusted with no significant impact to the overall fair value measure.

The following table sets forth, by level within the three-level fair value hierarchy that ranks the inputs used to measure fair value by their reliability, the Company's financial assets and liabilities that were accounted for at fair value as of June 30, 2009 and December 31, 2008:

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

Southwest Gas Corporation and its subsidiaries (the “Company”) consist of two business segments: natural gas operations (“Southwest” or the “natural gas operations” segment) and construction services.

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

On a seasonally adjusted basis as of June 30, 2009, Southwest had 1,809,000 residential, commercial, industrial, and other natural gas customers, of which 978,000 customers were located in Arizona, 653,000 in Nevada, and 178,000 in California. Residential and commercial customers represented over 99 percent of the total customer base. During the twelve months ended June 30, 2009, 54 percent of operating margin was earned in Arizona, 34 percent in Nevada, and 12 percent in California. During this same period, Southwest earned 86 percent of operating margin from residential and small commercial customers, 5 percent from other sales customers, and 9 percent from transportation customers. These general patterns are expected to continue.

Southwest recognizes operating revenues from the distribution and transportation of natural gas (and related services) to customers. Operating margin is the measure of gas operating revenues less the net cost of gas sold. Management uses operating margin as a main benchmark in comparing operating results from period to period. The principal factors affecting operating margin are general rate relief, weather, conservation and efficiencies, and customer growth. Of these, weather is the primary reason for volatility in margin. Variances in temperatures from normal levels, especially in Arizona where rates are highly leveraged, have a significant impact on the margin and associated net income of the Company.

NPL Construction Co. (“NPL” or the “construction services” segment), a wholly owned subsidiary, is a full-service underground piping contractor that provides utility companies with trenching and installation, replacement, and maintenance services for energy distribution systems. NPL currently operates in 19 major markets nationwide. Construction activity is cyclical and can be significantly impacted by changes in general and local economic conditions, including the housing market, interest rates, employment levels, job growth, the equipment resale market, and local and federal tax rates. Generally, revenues and profits are lowest during the first quarter of the year due to less favorable winter weather conditions. Operating results typically improve as more favorable weather conditions occur during the summer and fall months.

This Management’s Discussion and Analysis (“MD&A”) of Financial Condition and Results of Operations should be read in conjunction with the consolidated financial statements and the notes thereto, as well as the MD&A, included in the 2008 Annual Report to Shareholders, which is incorporated by reference into the 2008 Form 10-K, and the first quarter 2009 Form 10-Q.

Executive Summary

The items discussed in this Executive Summary are intended to provide an overview of the results of the Company’s operations. As needed, certain items are covered in greater detail in later sections of management’s discussion and analysis. As reflected in the table below, the natural gas operations segment accounted for an average of 88 percent of twelve-month-to-date consolidated net income over the past two years. As such, management’s discussion and analysis 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 the results for a full year.

Contribution to consolidated net income (loss) from natural gas operations improved $2.2 million in the second quarter of 2009 compared to same period in 2008. The improvement in contribution primarily resulted from a $3.7 million increase in the cash surrender values of COLI policies in the second quarter of 2009 compared to a $500,000 decline in the second quarter of 2008. The construction services contribution was relatively consistent between quarters.

2nd Quarter 2009 Overview

Gas operations highlights include the following:

·	Operating margin increased approximately $1 million, or less than 1 percent, compared to the prior-year’s quarter as the positive impact of rate changes ($4 million) was substantially offset by the negative impacts of conservation/energy efficiencies ($2 million) and weather ($1 million)

·	Operating expenses increased three percent between quarters

·	Significant increase in COLI cash surrender values

·	Net financing costs decreased $2.4 million between quarterly periods

·	Liquidity position remains strong

·	Nevada general rate case filing progressing on schedule

Customers. During the twelve months ended June 30, 2009, Southwest completed 25,000 first-time meter sets. These meter sets led to just 3,000 net additional active meters between June 2008 and June 2009 on a seasonally adjusted basis. The difference between first-time meter sets and incremental active meters indicates a continuing build-up of unoccupied homes, continuing a trend first experienced during 2007. Southwest is projecting continued sluggish net growth (1% or less) for 2009 as high foreclosure rates and recessionary conditions persist throughout its service territories. Once housing supply and demand come back into balance, Southwest expects to experience a correction in which customer additions exceed first-time meter sets. Although management cannot predict the timing of a turn around, it is not likely to occur in the near term.

Weather. The rate structures in each of Southwest’s three states provide varying levels of protection from risks that drive operating margin volatility, particularly weather risk. During the first six months of 2009, the estimated weather impact on operating margin was a reduction of $17 million, including $13 million from the first quarter when Arizona experienced one of its warmest winters in 100 years. For comparison purposes, during the first half of 2008, weather resulted in an estimated favorable operating margin impact of $1 million.

In Southwest’s California service territories, weather impacts were completely offset by the margin tracking mechanism allowing margin to grow as authorized in its most recent general rate case. In Nevada, the negative impacts were mitigated by a declining block rate structure. Most of the reduction occurred in Arizona, where rates are highly leveraged and a single block rate structure is in effect. In addition, the heating season is fairly condensed in Arizona, therefore variations from “normal” temperatures can cause material volatility in operating margin as over 50 percent of Southwest’s annual operating margin is normally earned in Arizona.

Conservation, Energy Efficiencies, and Economic Impacts on Consumption. A significant portion of Southwest’s operating margin (primarily in Arizona and partially in Nevada) is recognized based on the volumetric usage of its customers. Historically the impacts of this rate design methodology have been most pronounced when temperatures varied from normal levels. Over the longer-term, average usage has also declined due to new home construction practices and energy efficient appliances. Recently, the continued downturn in the economy and associated pro-active conservation efforts have resulted in an unprecedented drop in average per-customer usage. For the quarter and six months ended June 30, 2009, the estimated impact of these non-weather-related volumetric declines was a reduction to operating margin of $2 million and $8 million, respectively. Management expects this trend to continue until economic conditions improve. The decoupling methodology requested in the recent Nevada rate case, if approved as proposed, would mitigate this impact in Nevada. Management continues to work with regulators in Arizona to establish a decoupling methodology that would allow the Company to support and encourage conservation efforts without jeopardizing the recognition of authorized operating margin.

Company-Owned Life Insurance (“COLI”). Southwest has life insurance policies on members of management and other key employees to indemnify itself against the loss of talent, expertise, and knowledge, as well as to provide indirect funding for certain nonqualified benefit plans. The COLI policies have a combined net death benefit value of approximately $137 million at June 30, 2009. The net cash surrender value of these policies (which is the cash amount that would be received if Southwest voluntarily terminated the policies) is approximately $51 million at June 30, 2009 and is included in the caption “Other property and investments” on the balance sheet. Policies with approximately $2.3 million of additional cash surrender value were purchased in the second quarter of 2009. Cash surrender values are directly influenced by the investment portfolio underlying the insurance policies. This portfolio includes both equity and fixed income (mutual fund) investments. As a result, generally the cash surrender value (but not the net death benefit) moves up and down consistent with the movements in the broader stock and bond markets. See the Other Income (Deductions) section of Note 1 - Nature of Operations and Basis of Presentation for additional details. Current tax regulations provide for tax-free treatment of life insurance (death benefit) proceeds. Therefore, the changes in the cash surrender value components of COLI policies as they progress toward the ultimate death benefits are also recorded without tax consequences. Currently, the Company intends to hold the COLI policies for their duration and purchase additional policies as necessary.

Liquidity. During 2008, significant attention was paid to companies’ liquidity and credit risks. Focus on these risks will likely continue given the current national economic environment. The Company has experienced no significant impacts to its liquidity position from the ongoing credit crisis. Southwest believes its liquidity position remains strong for several reasons. First, Southwest has a $300 million credit facility maturing in May 2012, $150 million of which is designated for working capital needs. The facility is composed of eight major banking institutions. Historically, usage of the facility has been low and concentrated in the first half of the winter heating period when gas purchases require temporary financing. Second, natural gas prices have remained low and beneficial rate mechanisms have resulted in steady gas-cost related operating cash flows. Third, Southwest has no significant debt maturities prior to February 2011. Because of Southwest’s strong liquidity position, in December 2008, Southwest was able to take advantage of the current credit market by repurchasing $75 million of IDRBs at a net deferred gain of $14 million.

Credit Ratings. In April 2009, Standard & Poor’s Ratings Services (“S&P”) upgraded the Company’s unsecured long-term debt ratings from BBB- (with a positive outlook) to BBB (with a stable outlook). S&P cited the Company’s stronger financial performance due to reduced debt leverage and the recent general rate increase in the Company’s Arizona service territory as reasons for the upgrade. The change in credit rating will result in an annualized estimated decrease of $200,000 to $300,000 in interest expense and fees on existing variable-rate debt.

Contribution to consolidated net income from natural gas operations improved $2.2 million in the second quarter of 2009 compared to 2008. The improvement in contribution reflects higher other income and operating margin and the benefit of lower financing costs, partially offset by an increase in operating expenses.

Operating margin increased by approximately $1 million in the second quarter of 2009 compared to the second quarter of 2008. Net rate changes positively impacted margin by approximately $4 million, consisting of rate relief of $6 million in Arizona and $1 million in California, partially offset by a $3 million decrease related to the return to a seasonal margin methodology in California. Conservation resulting from current economic conditions and energy efficiency negatively impacted operating margin by $2 million. Weather changes between quarters resulted in a $1 million margin decrease as somewhat warmer-than-normal temperatures were experienced during both quarters. Customer growth was not a factor as only 3,000 net new customers (on a comparative seasonally adjusted basis) were added during the last twelve months.

Operations and maintenance expense increased $3.2 million, or four percent, principally due to the impact of general cost increases.

Depreciation expense increased approximately $600,000, or one percent, as a result of additional plant in service, partially offset by lower depreciation rates in California in 2009. Average gas plant in service for the current period increased $203 million, or five percent, compared to the corresponding period a year ago. This was attributable to the upgrade of existing operating facilities and the expansion of the system.

Other income increased $3.1 million between quarters as the cash surrender values of COLI policies increased by $3.7 million in the second quarter of 2009 compared to a reduction of $500,000 in the prior-year quarter, partially offset by lower interest income.

Net financing costs decreased $2.4 million between the second quarters of 2009 and 2008 primarily due to lower average debt outstanding, including the redemption of $75 million of long-term debt in December 2008, and reduced interest rates associated with Southwest’s commercial credit and other variable-rate facilities.

Contribution to consolidated net income from natural gas operations increased $2.7 million in the first six months of 2009 compared to the same period a year ago. The increase in contribution was primarily caused by reduced financing costs and increased other income, partially offset by increased operating expenses.

Operating margin was relatively flat in the first six months of 2009 compared to the first six months of 2008. Positive impacts to operating margin from rate relief and rate changes were nearly $26 million, consisting of rate relief of $15 million in Arizona and $2 million in California and nearly $9 million related to the return to a seasonal margin methodology in California. Differences in heating demand, caused primarily by weather variations, negatively impacted operating margin by approximately $18 million as overall temperatures in the current period were significantly warmer than normal ($17 million), while temperatures were somewhat colder than normal ($1 million) in the corresponding period in 2008. Energy efficiency and conservation resulting from the sluggish economy negatively impacted operating margin by an estimated $8 million. Customer changes had a nominal impact on operating margin.

Operations and maintenance expense increased $2.7 million, or two percent, principally due to the impact of general cost increases. Labor efficiencies, including those from the conversion to electronic meter reading, mitigated the increase in operations and maintenance expense.

Depreciation expense increased $2.3 million, or three percent, as a result of construction activities, partially offset by lower depreciation rates in California in 2009. Average gas plant in service increased $208 million, or five percent, as compared to the first six months of 2008. The increase reflects ongoing capital expenditures for the upgrade of existing operating facilities and the expansion of the system.

Other income increased $2.8 million between periods as the cash surrender values of COLI policies increased by $2.1 million in the first half of 2009 compared to a reduction of $2.6 million in the first half of 2008, partially offset by a $1.6 million decrease in interest income.

Net financing costs decreased $5.6 million between the first six months of 2009 and the same period in 2008 primarily due to lower average debt outstanding, including the redemption of $75 million of long-term debt in December 2008, and reduced interest rates associated with Southwest’s commercial credit and other variable-rate facilities.

Contribution to consolidated net income	$	56,437		$	71,147

Contribution to consolidated net income from natural gas operations decreased $14.7 million in the current twelve-month period compared to the same period a year ago. The decline in contribution was primarily caused by lower other income, higher operating expenses, and lower operating margin, partially offset by reduced financing costs.

Operating margin decreased a net $4 million between periods. Rate relief and rate changes provided $28 million of operating margin, consisting of rate relief of $17 million in Arizona and $2 million in California, and nearly $9 million of timing differences related to the return to a seasonal margin methodology in California. Customer growth contributed $2 million in operating margin. Differences in heating demand caused primarily by weather variations between periods resulted in a $22 million operating margin decrease as warmer-than-normal temperatures were experienced during both periods (during the twelve-month period of 2009, operating margin was negatively impacted by $29 million, while the negative impact in the twelve-month period of 2008 was $7 million). Conservation resulting from current economic conditions and energy efficiency negatively impacted operating margin by $12 million.

Operations and maintenance expense increased $9 million, or three percent, principally due to the impact of general cost increases. Labor efficiencies, primarily from the conversion to electronic meter reading and other cost containment efforts, mitigated the increase in operations and maintenance expense.

Depreciation expense increased $7.2 million, or four percent, as a result of additional plant in service. Average gas plant in service for the twelve-month period of 2009 increased $223 million, or six percent, as compared to the twelve-month period of 2008. This was attributable to the upgrade of existing operating facilities and the expansion of the system.

Other income decreased $8.3 million between the twelve-month periods of 2009 and 2008. This was primarily due to a $7.4 million decline in the cash surrender values of COLI policies in the current period compared to cash surrender value declines in the prior period of $3.2 million and a $2.7 million reduction in interest income between the twelve-month periods primarily due to the recovery of previously deferred purchased gas cost receivables.

Net financing costs decreased $8.7 million between the twelve-month periods of 2009 and 2008 primarily due to lower average debt outstanding and reduced interest rates associated with Southwest’s commercial credit and other variable-rate facilities.

Results of Construction Services

Contribution to consolidated net income from construction services for the three months ended June 30, 2009 decreased $40,000 compared to the same period of 2008. The reduction was primarily due to reduced revenues, partially offset by lower operating and finance costs. Gains on sales of equipment were relatively flat between the comparative quarterly periods.

Revenues decreased $23.4 million due primarily to a reduction in new construction work. The reduced workload resulted in a corresponding decrease in construction expenses ($21.8 million). In addition, lower fuel and fuel-related expenses and cost-saving initiatives contributed to the decline in construction expenses. Interest expense decreased $199,000 between periods due to a reduction in long-term borrowings.

Contribution to consolidated net income from construction services for the six months ended June 30, 2009 increased $270,000 compared to the same period of 2008. The improvement was primarily due to lower financing costs and increased gains on equipment sales between periods. Gains on sales of equipment were $1.9 million for the six months ended June 30, 2009 and $1.7 million for the corresponding period of 2008.

Revenues decreased $40.9 million due primarily to a reduction in new construction work. Construction expenses decreased $39.4 million between periods primarily due to the reduced workload, lower fuel and fuel-related expenses and cost-saving initiatives. Interest expense declined $307,000 between periods due to a reduction in long-term borrowings.

Contribution to consolidated net income from construction services for the twelve-month period of 2009 decreased $1.6 million compared to the same period of 2008. This decrease was due primarily to a reduction in the volume of new construction work. Higher fuel cost and fuel-related expenses in the third quarter of 2008 also contributed to the decrease in contribution. Gains on sales of equipment were $2.3 million for the twelve-month period of 2009 and $2.2 million for the twelve-month period of 2008.

Revenues decreased $42.5 million due primarily to a reduction in the volume of higher-margin new construction work resulting from the general slow down in the new housing market. New construction work has been largely replaced by infrastructure maintenance and improvement work, which generally yields lower profit margins. There was also a decrease in the amount of work from existing blanket contracts. Construction expenses decreased $38.7 million due primarily to the reduction in construction work, partially offset by the higher fuel and fuel-related expenses noted above.

NPL’s revenues and operating profits are influenced by weather, customer requirements, mix of work, local economic conditions, bidding results, and the equipment resale market. Generally, revenues and profits are lowest during the first quarter of the year due to unfavorable winter weather conditions. Operating results typically improve as more favorable weather conditions occur during the summer and fall months.

Rates and Regulatory Proceedings

California General Rate Cases. Effective January 2009 Southwest received general rate relief in California. The California Public Utilities Commission (“CPUC”) decision authorized an overall increase of $2.8 million in 2009 with an additional $400,000 deferred to 2010. In addition, attrition increases were approved to be effective for the years 2010-2013 of 2.95% in southern and northern California and $100,000 per year for the South Lake Tahoe rate jurisdiction. The CPUC also authorized a return to a seasonal margin methodology which will result in significant quarterly swings in reported operating margin (2009 versus 2008). In addition to the comparative operating margin increase of $10.8 million recognized in the first half of 2009, a decrease of $9 million in the third quarter and an increase of $1 million for the fourth quarter of 2009 are expected. The CPUC also authorized lower depreciation rates which reduce annualized depreciation expense by $3 million.

SOUTHWEST GAS CORPORATION	Form 10-Q

Nevada General Rate Case. Southwest filed a general rate application with the Public Utilities Commission of Nevada (“PUCN”) in April 2009 requesting an increase in authorized operating revenues of $28.8 million, or 5.9 percent in the Company’s southern Nevada rate jurisdiction and $1.7 million, or 1.4 percent in the northern Nevada rate jurisdiction. The Company is also seeking to implement a decoupled rate structure based on recently established PUCN regulations that will help stabilize operating margin and allow the Company to more aggressively pursue customer conservation opportunities through implementation of substantive conservation and energy efficiency programs. The proceeding is currently in the discovery phase. Testimony from PUCN staff, Department of Ratepayer Advocates, and intervenors is due in August 2009. Hearings are scheduled for September, with an Order and new rates expected in the fourth quarter of 2009. Southwest's last general rate increase occurred in 2004.

FERC General Rate Case. Paiute Pipeline Company, a subsidiary of the Company, filed a general rate case with the Federal Energy Regulatory Commission (“FERC”) in February 2009. The filing fulfills an obligation from the settlement agreement reached in the 2005 Paiute general rate case. The application requests an increase in operating revenues of approximately $3.9 million. The proceeding is currently in the discovery phase. New rates are anticipated to go into effect subject to refund within 180 days of filing.

Arizona energy efficiency and decoupling proceeding. The Arizona Corporation Commission (“ACC”) recently convened a series of workshops to evaluate “rate and regulatory incentives” and establish standards to promote energy efficiency and conservation for utility customers. In conjunction with these workshops, Southwest and other interested parties submitted proposed regulations to the ACC in June 2009. Rate designs which would decouple revenues from customer usage have been the topic of much discussion in the proceeding, and were incorporated in several of the parties’ draft regulations. The ACC Staff is reviewing the proposals and will develop a draft regulation for consideration by the ACC. A final decision in the matter may be made by year-end.

PGA Filings

The rate schedules in all of Southwest’s service territories contain provisions that permit adjustments 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- and under-collections. At June 30, 2009, over-collections in all service territories resulted in a liability of $82.2 million on the Company’s balance sheet. 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 income statement components. These include Gas operating revenues, Net cost of gas sold, Net interest deductions, and Other income (deductions).

As of June 30, 2009, December 31, 2008, and June 30, 2008, Southwest had the following outstanding PGA balances payable (millions of dollars):

	June 30, 2009			December 31, 2008			June 30, 2008
Arizona	$	(25.0	)	$	(9.6	)	$	(4.6	)

California		(7.7	)		(2.1	)		(2.1	)
	$	(82.2	)	$	(33.1	)	$	(31.5	)

Capital Resources and Liquidity

Cash on hand and cash flows from operations have generally been sufficient over the past two years to provide for net investing activities (primarily construction expenditures and property additions). During the past two years, the Company has been able to reduce the net amount of debt outstanding (including short-term borrowings). The Company’s capitalization strategy is to maintain an appropriate balance of equity and debt (including subordinated debentures and short-term borrowings).

SOUTHWEST GAS CORPORATION	Form 10-Q
June 30, 2009

To facilitate future financings, the Company has a universal shelf registration statement providing for the issuance and sale of registered securities from time to time, which may consist of secured debt, unsecured debt, preferred stock, or common stock. The number and dollar amount of securities issued under the universal shelf registration statement, which was filed with the SEC and automatically declared effective in December 2008, will be determined at the time of the offerings and presented in the applicable prospectuses.

Cash Flows

Operating Cash Flows. Cash flows provided by consolidated operating activities increased $46.5 million in the first six months of 2009 as compared to the same period in 2008. The primary driver of the change was temporary fluctuations in working capital components. Operating cash flows were also impacted by an increase in net income and depreciation and amortization between the six-month periods.

In February 2009, the American Recovery and Reinvestment Act of 2009 (“Act”) was signed into law. This Act provides a 50 percent bonus tax depreciation deduction for qualified property acquired or constructed and placed in service in 2009. Southwest estimates that the bonus depreciation deduction will defer the payment of approximately $22 million of federal income taxes during 2009 to future periods.

Investing Cash Flows. Cash used in consolidated investing activities increased $10 million in the first six months of 2009 as compared to the same period in 2008. The increase was primarily due to the return of an exchange fund deposit in 2008, partially offset by reductions in construction expenditures and equipment purchases, a result of the new housing market slowdown. Net collections of customer advances decreased approximately $8.3 million between the periods, another consequence of the construction slowdown.

Financing Cash Flows. Cash used in consolidated financing activities increased $20.6 million during the first six months of 2009 as compared to the same period in 2008 primarily due to fluctuations in borrowings under Southwest’s commercial credit facility and a net reduction of long-term debt. Dividends paid increased in the first six months of 2009 as compared to 2008 as a result of a quarterly dividend increase and an increase in the number of shares outstanding.

The capital requirements and resources of the Company generally are determined independently for the natural gas operations and construction services segments. Each business activity is generally responsible for securing its own financing sources. The capital requirements and resources of the construction services segment are not material to the overall capital requirements and resources of the Company.

Gas Segment Construction Expenditures and Financing

Southwest continues to experience customer growth, albeit at a much slower pace than in the recent past. The Company also recently completed the construction of two new operations centers for its Southern Nevada Division. During the twelve-month period ended June 30, 2009, construction expenditures for the natural gas operations segment were $258 million. Approximately 60 percent of these expenditures represented new construction and the balance represented costs associated with routine replacement of existing transmission, distribution, and general plant. Cash flows from operating activities of Southwest were $301 million which provided sufficient funding for construction expenditures and dividend requirements of the natural gas operations segment.

Southwest estimates natural gas segment construction expenditures during the three-year period ending December 31, 2011 will be approximately $720 million. Of this amount, approximately $260 million is expected to be incurred in 2009. During the three-year period, cash flows from operating activities of Southwest are estimated to fund over 85 percent of the gas operations total construction expenditures and dividend requirements. Southwest also has $200 million in long-term debt due in 2011. During the three-year period, the Company expects to raise $40 million to $50 million from its various common stock programs. Any cash requirements not met by operating activities are expected to be provided by existing credit facilities and/or other external financing sources. The timing, types, and amounts of these additional external financings will be dependent on a number of factors, including conditions in the

SOUTHWEST GAS CORPORATION	Form 10-Q
June 30, 2009

capital markets, timing and amounts of rate relief, growth levels in Southwest service areas, and earnings. These external financings may include the issuance of both debt and equity securities, bank and other short-term borrowings, and other forms of financing.

During the six months ended June 30, 2009, the Company issued shares of common stock through the Dividend Reinvestment and Stock Purchase Plan (“DRSPP”) and Employee Investment Plan, raising approximately $11 million. No other financing activities were necessary during the period.

Dividend Policy

The Company has a common stock dividend policy which states that common stock dividends will be paid at a prudent level that is within the normal dividend payout range for its respective businesses, and that the dividend will be established at a level considered sustainable in order to minimize business risk and maintain a strong capital structure throughout all economic cycles. In February 2009, the Board of Directors increased the quarterly dividend payout from 22.5 cents to 23.75 cents per share, effective with the June 2009 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, Southwest’s ability to access and obtain capital from external sources, interest rates, changes in income tax laws, pension funding requirements, inflation, and the level of Company earnings. Natural gas prices and related gas cost recovery rates have historically had the most significant impact on Company liquidity.

On an interim basis, Southwest generally 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, 2009, the combined balance in the PGA accounts totaled an over-collection of $82 million. See PGA Filings for more information on recent regulatory filings.

In the current challenging capital market environment, the Company has not, to date, experienced significant impacts on its financing activities. Limited availability of commercial paper and temporarily higher interest rates in 2008 are the most significant impacts the Company has experienced. The Company has a $300 million credit facility that expires in May 2012. Southwest has designated $150 million of the $300 million facility as long-term debt and the remaining $150 million for working capital purposes. At June 30, 2009, $91 million was outstanding on the long-term portion and no borrowings were outstanding on the short-term portion of the credit facility. The credit facility can be used as necessary to meet liquidity requirements, including temporarily financing under-collected PGA balances, if any. This credit facility has been, and is expected to continue to be, adequate for Southwest’s working capital needs outside of funds raised through operations and other types of external financing. Management believes the Company currently has a solid liquidity position.

The following table sets forth the ratios of earnings to fixed charges for the Company. Due to the seasonal nature of the Company’s business, these ratios are computed on a twelve-month basis:

	For the Twelve Months Ended
	June 30,	December 31,
	2009	2008

Ratio of earnings to fixed charges	2.11	2.01

SOUTHWEST GAS CORPORATION	Form 10-Q
June 30, 2009

Earnings are defined as the sum of pretax income plus fixed charges. Fixed charges consist of all interest expense including capitalized interest, one-third of rent expense (which approximates the interest component of such expense), and net amortized debt costs.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

See Item 7A. Quantitative and Qualitative Disclosures about Market Risk in the Company’s 2008 Annual Report on Form 10-K filed with the SEC. No material changes have occurred related to the Company’s disclosures about market risk.

SOUTHWEST GAS CORPORATION	Form 10-Q
June 30, 2009

ITEM 4. CONTROLS AND PROCEDURES

The Company has established disclosure controls and procedures that are designed to provide reasonable assurance that information required to be disclosed in reports filed or submitted under the Securities Exchange Act of 1934 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 our management, including our 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, 2009, management of the Company, including the Chief Executive Officer and Chief Financial Officer, believe 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 controls over financial reporting during the second quarter of 2009 that have materially affected, or are likely to materially affect, the Company’s internal controls over financial reporting.
