Note 1 - Summary of Significant Accounting Policies

Nature of Operations. Southwest Gas Corporation (the Company) is comprised of two segments: natural gas operations (Southwest or the natural gas operations segment) and construction services. Southwest purchases, transports, and distributes natural gas to customers 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. 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. Northern Pipeline Construction Co. (Northern or the construction services segment), a wholly owned subsidiary, is a full-service underground piping contractor which provides utility companies with trenching and installation, replacement, and maintenance services for energy distribution systems.

Basis of Presentation. The 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 (SEC). Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations. The preparation of the 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 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 presentation of the results for the interim periods, have been made. It is suggested that these consolidated financial statements be read in conjunction with the consolidated financial statements and the notes thereto included in the 2001 Annual Report to Shareholders, which is incorporated by reference into the 2001 Form 10-K.

Intercompany Transactions. The construction services segment recognizes revenues generated from contracts with Southwest (see Note 2 below). Accounts receivable for these services were $6.8 million at March 31, 2002 and $4.3 million at December 31, 2001. The accounts receivable balance, revenues, and associated profits are included in the 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.”

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

The Company is principally engaged in the business of purchasing, transporting, and distributing natural gas. 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 and transporter 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.

Southwest purchases, transports, and distributes natural gas to approximately 1,411,000 residential, commercial, industrial and other customers, of which 56 percent are located in Arizona, 35 percent are in Nevada, and 9 percent are in California. During the twelve months ended March 31, 2002, Southwest earned 58 percent of operating margin in Arizona, 34 percent in Nevada, and 8 percent in California. During this same period, Southwest earned 82 percent of operating margin from residential and small commercial customers, 9 percent from other sales customers, and 9 percent from transportation customers. The percentage of transportation customers when compared to previous years reflects a shift by a number of large commercial and industrial customers from transportation service to sales service.

Northern is a full-service underground piping contractor which provides utility companies with trenching and installation, replacement, and maintenance services for energy distribution systems.

Capital Resources and Liquidity

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.

Southwest continues to experience significant customer growth. Financing this growth has required large amounts of capital to pay for new transmission and distribution plant, to keep up with consumer demand. During the twelve-month period ended March 31, 2002, capital expenditures for the natural gas operations segment were $250 million. Approximately 72 percent of these current-period 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 (net of dividends) provided $232 million of the required capital resources pertaining to these construction expenditures. The remainder was provided from external financing activities. Such cash flows were favorably impacted by changes in the purchased gas adjustment (PGA) recovery rates resulting in the collection of previously deferred purchased gas costs from customers and general rate relief.

In March 2002, the Job Creation and Worker Assistance Act of 2002 (Act) was signed into law. This Act provides a three-year, 30 percent “bonus” tax depreciation deduction for businesses. Southwest estimates the bonus depreciation deduction will reduce federal income taxes paid by approximately $40 million to $50 million over the years 2002 through 2004.

Southwest estimates construction expenditures during the three-year period ending December 31, 2004 will be approximately $675 million. Of this amount, $225 million are expected to be incurred in 2002. During the three-year period, cash flow from operating activities (net of dividends) is estimated to fund approximately 80 percent of the gas operations total construction expenditures, including the impacts of the Act. The remaining cash requirements are expected to be provided by 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 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. Southwest has a total of $400 million in securities registered with the SEC which are available for future financing needs.

6

Current maturities of long-term debt were $238 million at March 31, 2002. In June 2002, the $350 million revolving credit facility, of which $200 million is designated as long-term debt ($130 million outstanding at March 31,  2002), and the $100 million Series F debentures will mature. The Company intends to refinance the long-term portion of the revolving credit agreement ($200 million) and the Series F debentures on a long-term basis and is actively in discussions with its financial advisors over the timing, types and amounts of these external financings. The transactions are expected to be completed during the second quarter of 2002. Once the debt has been refinanced, the Current maturities of long-term debt line item should return to normal levels. The Company also intends to maintain short-term borrowing capacity at a level sufficient to cover working capital needs.

The rate schedules in all of the service territories contain PGA clauses, which permit adjustments to rates as the cost of purchased gas changes. 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 December 31, 2001 the combined balances in PGA accounts totaled $84 million. At March 31, 2002 the combined balances reflected an over collection of $2 million. Southwest utilizes short-term borrowings to finance PGA balances. Southwest has short-term borrowing capacity of $150 million, which is considered adequate to meet anticipated needs. See Rates and Regulatory Proceedings for the status of current PGA filings.

In January 2002, the Company sold all of its interests in undeveloped property located in northern Arizona. The property was originally acquired as a potential site for underground natural gas storage during the gas supply shortages of the 1970s, but was never developed. Proceeds from the sale were $20 million including a $5 million receivable due September 2002. The sale resulted in a one-time pre-tax gain of $8.9 million, which was recognized in the first quarter of 2002.

Preferred securities distributions		1,369		1,369
Income tax expense		26,624		20,443
Contribution to consolidated net income	$	42,487	$	33,329

Contribution from natural gas operations increased $9.2 million in the first quarter of 2002 compared to the same period a year ago. The increase was the result of higher operating margin and improved other income (expense), partially offset by increased operating expenses.

Operating margin was $182 million, a $14 million increase over the $168 million earned during the first quarter of 2001. The increase was the result of general rate relief and customer growth, partially offset by the impacts of weather between periods. General rate relief accounted for $15 million of the increase. Effective November 2001, annualized rate relief of $21.6 million was granted in Arizona and effective December 2001, annualized rate relief of $19.4 million was granted in Nevada. The Company added 59,000 customers during the last 12 months who contributed $5 million in incremental margin. Operating margin was reduced by $6 million between periods due to weather, as the prior period was colder than normal.

Operations and maintenance expense increased $5.1 million, or eight percent, reflecting general cost increases and costs associated with the continued expansion and upgrading of the gas system to accommodate customer growth.

Depreciation expense and general taxes increased $2.5 million, or seven percent, as a result of construction activities. Average gas plant in service increased $194 million, or eight percent, as compared to the first quarter of 2001. The increase reflects ongoing capital expenditures for the upgrade of existing operating facilities and the expansion of the system to accommodate continued customer growth.

8

Other income improved $7.7 million between periods. The current period includes a one-time pre-tax gain of $8.9 million on the sale of undeveloped property, partially offset by a $1.5 million reduction in interest income primarily earned on the deferred PGA account balances.

Net interest deductions decreased $1.1 million, or six percent between periods. This primarily resulted from a reduction in the outstanding balance of the Company’s revolving credit facility due to strong cash flows, following recovery of previously deferred purchased gas costs. Also contributing were low interest rates on variable rate debt instruments.

Preferred securities distributions		5,475		5,475
Income tax expense		22,279		17,411
Contribution to consolidated net income	$	41,784	$	42,873

Contribution to consolidated net income decreased $1.1 million in the current twelve-month period compared to the same period a year ago. Growth in operating margin and improvement in other income (expense) was more than offset by higher operating and financing costs.

Operating margin increased $29.6 million between periods. Customer growth, coupled with increased margin from electric generation and industrial customers during 2001, contributed $29 million in incremental margin, while rate relief added $20 million. Differences in heating demand caused by weather variations between periods resulted in a $19 million margin decrease. Modestly warmer-than-normal temperatures experienced during the current period reduced margin by $8 million. Prior-period margin was $11 million higher than expected due to temperatures that were ten percent colder than normal.

Operations and maintenance expense increased $24.1 million, or ten percent, reflecting general increases in labor and maintenance costs, higher uncollectible expenses, and incremental operating expenses associated with providing service to a steadily growing customer base.

Depreciation expense and general taxes increased $12 million, or nine percent, as a result of additional plant in service. Average gas plant in service for the current twelve-month period increased $186 million, or eight 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 to accommodate new customers.

Other income (expense) improved $15.5 million between periods. The current period includes a one-time pretax gain of $8.9 million for the sale of undeveloped property, a $3 million nonrecurring pretax gain on the sale of certain assets recognized in the fourth quarter of 2001, and an incremental $3.8 million of interest income primarily earned on deferred PGA account balances.

Rates and Regulatory Proceedings

Nevada General Rate Cases. In July 2001, Southwest filed general rate applications with the Public Utilities Commission of Nevada (PUCN) seeking approval to increase annualized revenues by $21.7 million in its southern Nevada rate jurisdiction and $7.7 million in its northern Nevada rate jurisdiction. In November 2001, Southwest received approval from the PUCN to increase rates by $13.5 million, or five percent, annually in southern Nevada and $5.9 million, or five percent, annually in northern Nevada effective December 2001. In January 2002, the PUCN settled several open issues in the case regarding rate design. Changes included increasing the residential basic service charge by $2.00 per month in both jurisdictions, which should improve revenue stability in Nevada. The changes were effective February 2002 and did not impact the amount of rate relief granted.

California General Rate Cases. In February 2002, Southwest filed general rate applications with the California Public Utilities Commission (CPUC) for its northern and southern California jurisdictions. The application seeks annual increases over a five-year period beginning January 2003, which cumulatively amount to $6.3 million in northern California and $17.2 million in southern California. For 2003, an annualized $2.7 million, or 13 percent, revenue increase was requested for the northern jurisdiction and an annualized $6.7 million, or eight percent, revenue increase was requested for the southern jurisdiction. Additional smaller annual revenue increases are proposed in the subsequent years of the application through 2007. Hearings are expected to begin in the third quarter of 2002. The last general rate increases received in California were January 1998 in northern California and January 1995 in southern California.

PGA Filings

Arizona PGA Filings. In Arizona, Southwest adjusts rates monthly for changes in purchased gas costs, within pre-established limits. In January 2002, Southwest filed an advice letter with the Arizona Corporation Commission to eliminate a temporary rate adjustment surcharge, which was otherwise set to expire at the end of the second quarter of 2002. This action was taken in recognition of moderating gas costs and projections of PGA balancing account activity. The filing was approved effective February 2002, and reduces revenues by $31.9 million annually with no reduction to margin.

Nevada PGA Filings. In December 2001, Southwest submitted an out-of-cycle PGA filing to the PUCN for a $29.2 million decrease for southern Nevada customers. In January 2002, an additional decrease of $13.9 million was requested. The total of the two filings, $43.1 million, was agreed to in a settlement among all parties and approved by the PUCN effective February 2002. The filings were made in advance of the scheduled annual date to allow customers to receive the benefit of decreases experienced in natural gas costs. PGA changes impact cash flows but have no direct impact on profit margin.

California Order Instituting Investigation (OII). In July 2001, the CPUC ordered an investigation into the reasonableness of Southwest natural gas procurement practices and costs from June 1999 through May 2001, and related measures taken to minimize gas costs beyond May 2001. During the third quarter of 2001, Southwest filed a detailed report and testimony with the CPUC on these matters for both its northern and southern California service territories. The OII resulted from complaints by southern California customers about the size of monthly PGA rate increases that were necessary due to the unusually high cost of natural gas during the winter of 2000-2001. In regards to the southern California jurisdiction, the Office of Ratepayer Advocate and the County of San Bernardino recommended disallowances of $7.3 million and $11.7 million, respectively. No issues were raised related to the northern California rate jurisdiction. The proposed disallowances were based solely on decisions by Southwest not to purchase gas for storage during the winter of 2000-2001. Hearings were held in January 2002 with a final decision anticipated in the second quarter of 2002. Southwest defended its decisions related to storage, based on testimony which demonstrated that injecting additional volumes of natural gas into storage during the 2000 injection season (April through

10

September) could not be economically justified based on market conditions and price forecasts that existed at the time decisions were made. Management believes it has adequately defended the prudency of its gas procurement practices and, as a result, believes there is no legal basis for a disallowance.

Recently Issued Accounting Pronouncements

In June 2001, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards (SFAS) No. 143, “Accounting for Asset Retirement Obligations.” SFAS No. 143 requires entities to record the fair value of a liability for an asset retirement obligation in the period in which it is incurred. The asset retirement obligations included within the scope of SFAS No. 143 are those that are unavoidable as a result of the acquisition, construction, development, or normal operation of long-lived assets. The standard requires that a legal obligation associated with the retirement of tangible long-lived assets be recognized as a liability when incurred. When a liability for an asset retirement obligation is initially recorded, the entity capitalizes a cost by increasing the carrying amount of the related long-lived asset. Over time, the liability is accreted to its present value each period, and the capitalized cost is depreciated over the useful life of the related asset. Entities are also required to recognize period-to-period changes for the liability related to asset retirement obligations resulting from the passage of time and/or revisions to either the timing or the amount of the original estimate of undiscounted cash flows. Upon settlement of the liability, an entity either settles the obligation for its recorded amount or incurs a gain or loss. Upon initial application of SFAS No. 143, entities are required to recognize the following items in the statement of financial position: a liability for any existing asset retirement obligations adjusted for cumulative accretion to the date of adoption of SFAS No. 143, an asset retirement cost capitalized as an increase to the carrying amount of the associated long-lived asset, and accumulated depreciation for the capitalized cost. SFAS No. 143 is effective for financial statements issued for fiscal years beginning after June 15, 2002, with early adoption encouraged. Management has not yet quantified the effects of the new standard on the financial position or results of operations of the Company.
