Report of Independent Registered Public Accounting Firm
To the Participants and Administrator of
Southwest Gas Corporation Employees’ Investment Plan:
In our opinion, the accompanying statements of net assets available for benefits and the related statement of changes in net assets available for benefits present fairly, in all material respects, the net assets available for benefits of Southwest Gas Corporation Employees’ Investment Plan (the “Plan”) at December 31, 2005 and December 31, 2004, and the changes in net assets available for benefits for the year ended December 31, 2005 in conformity with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.
Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental Schedule H, Line 4i - Schedule of Assets (Held at End of Year) as of December 31, 2005 is presented for the purpose of additional analysis and is not a required part of the basic financial statements but is supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. This supplemental schedule is the responsibility of the Plan’s management. The supplemental schedule has been subjected to the auditing procedures applied in our audits of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole.

SOUTHWEST GAS CORPORATION
EMPLOYEES’ INVESTMENT PLAN
NOTES TO FINANCIAL STATEMENTS
(1) Description of Plan
The following description of the Southwest Gas Corporation Employees’ Investment Plan (the “Plan”), as amended, provides general information. Participants should refer to the Plan document for a more complete description of the Plan’s provisions.
General
The Plan is a voluntary defined contribution plan covering all employees of Southwest Gas Corporation (the “Company”). It is subject to the provisions of the Employee Retirement Income Security Act of 1974 (“ERISA”). The Plan’s assets invested in Company stock (consisting of (i) Company matching contributions and (ii) participant deferrals) are designated as an Employee Stock Ownership Plan (“ESOP”).
The ESOP invests primarily in qualifying employer securities. The non-ESOP portion of the Plan is a profit-sharing plan that is qualified under Code Sections 401(a) and 401(k). The ESOP portion of the Plan is a stock bonus plan and an employee stock ownership plan that is qualified under Code Sections 401(a) and 4975(e)(7) and described in ERISA Section 407(d)(6). The profit-sharing plan and the ESOP together are a single plan under Treasury Regulation Section 1.414(1)-1(b)(1). The Plan satisfies the requirements of ERISA and the trust fund maintained under the Plan is tax-exempt under Code Section 501(a).
Contributions
Participants may contribute up to 60 percent of their annual wages before bonuses and overtime. However, contributions may not exceed amounts promulgated by the Internal Revenue Code. The Company contributes to the Plan an amount equal to 50 percent of a participant’s contribution. The Company’s maximum contribution is three percent of a participant’s annual compensation before bonuses and overtime.
Participants Accounts
Each participant account is credited with the participant’s contribution and the portion contributed by the Company. The portion contributed by the participant is invested in the various funds according to the direction of the participant. The Company contributions are invested in the Southwest Gas Stock Fund. Upon attaining age 50, participants may elect the investment funds in which the present balance of Company contributions, as well as future Company matching contributions, will be invested.
Vesting
Participants are immediately vested in their voluntary contributions plus actual earnings thereon. Vesting in the contributions made by the Company and in the earnings thereon is based on years of continuous service as follows:
| Years of Service | Vested Percentage | ||
|---|---|---|---|
| One but less than two | 20 | ||
| Two but less than three | 40 | ||
| Three but less than four | 60 | ||
| Four but less than five | 80 | ||
| Five and over | 100 | ||
In the event of death, retirement, or total disability of a participant, Company contributions become fully vested irrespective of the years of service at the date of termination. Forfeitures as a result of a participant’s termination prior to vesting are reallocated to the remaining participants on a quarterly basis based on the employer contribution ratio. For the years ended December 31, 2005 and 2004, forfeitures of non-vested accounts reallocated to participants were approximately $28,000 and $44,000, respectively.

NOTES TO FINANCIAL STATEMENTS
Participant Loans
The Plan provides that participants may borrow against the balances in their accounts, subject to certain limitations specified in the Plan. Funds for loans are obtained through the liquidation of participants’ investment accounts. Payments on the loans include interest at a rate that approximates the prime rate, plus two percent. At December 31, 2005, outstanding loans had annual interest rates ranging from 6.00 percent to 11.50 percent. Principal and interest payments on a participant’s loan will be credited to the participant’s investment accounts in the same ratio as ongoing contributions. The maximum repayment period for participant loans is five years.
Payment of Benefits
If a participant terminates employment with the Company as a result of retirement, death, or permanent and total disability, such participant or designated beneficiary in the case of death, will be entitled to receive an amount equal to the value of his account at the end of the month immediately following termination of employment. Distributions from the Southwest Gas Stock Fund will be made in the Company’s common stock plus cash in lieu of fractional shares. A participant may apply to the Plan Committee to request a single lump sum payment in cash of the value of the Company’s common stock otherwise distributable to the participant. Distributions from other funds will be made in a single lump sum cash payment.
Distributions under the Plan will begin as soon as practicable, but not later than April 1 following the end of the Plan year in which the participant attains age 70-1/2 or terminates employment, if later. No distribution in excess of $1,000 will be made to employees at the time of termination of employment without the participant’s consent. A participant who is terminated and does not elect to take a distribution will continue to receive his share of investment income on all vested portions of his accounts until electing to receive distributions from the Plan. All distributions to beneficiaries of a participant must be made within five years after the participant’s death.
Plan Expenses
Plan-related expenses and any other costs of administering the Plan will be paid with funds from the Plan unless paid by the Company at its discretion. The Company paid all Plan expenses, except loan origination and maintenance fees, during 2005. Loan origination and maintenance fees paid by Plan participants for the year ended December 31, 2005 were $24,626.
Plan Administration
Fidelity Management Trust Company acts as the trustee and Fidelity Investment Institutional Operations Company, Inc. performs all recordkeeping of the Plan.
(2) Summary of Accounting Policies
Basis of Accounting
The financial statements of the Plan are prepared under the accrual method of accounting.
Use of Estimates
The preparation of financial statements in conformity with generally accepted accounting principles in the United States 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 changes in net assets during the reporting period. Actual results could differ from those estimates.

Investment Valuation and Income Recognition
All investments of the Plan are stated at quoted market value as of the date of the statement. Shares of mutual funds are valued at the net asset value of shares held by the Plan at year end. The Plan provides for investments in various investment securities including common stock of the Company. Investment securities, in general, are exposed to various risks, such as interest rate, credit, and overall market volatility risks. Due to the level of risk associated with certain investment securities and the amount invested in the Company’s common stock, it is reasonably possible that changes in the values of investment securities will occur in the near term and such changes could materially affect the amounts reported in the statements of net assets available for benefits. Loans to participants are valued at their outstanding principal amount, which approximates fair value.
Purchases and sales of securities are recorded on a trade-date basis. Dividends are recorded on the ex-dividend date.
(3) Investments
Investments representing five percent or more of Plan net assets are:

(5) Related-Party Transactions
Since the Company’s common stock is an investment held by the Plan, investments in this common stock represented transactions with parties-in-interest. Certain other plan investments are short-term deposits and investments, and shares of mutual funds managed by Fidelity Management Trust Company, the Trustee as defined by the Plan. These certain plan investments qualify as parties-in-interest transactions for which a statutory exemption exists. The following represents investments held by related parties:
| December 31, | 2005 |

|---|---|---|---|---|---|---|---|---|
| Southwest Gas Corporation | $ | 72,340,066 | 68,899,837 | |||||

| $ | 207,909,717 | $ | 191,775,740 | |||||
(6) Plan Termination
Although the Company expects to continue the Plan indefinitely, it reserves the right to amend or terminate the Plan at any time. Upon termination, partial termination, or complete discontinuance of contributions to the Plan, Company contributions will become fully vested.
(7) Federal Income Taxes
In April 2003, the Company received a favorable determination letter from the IRS stating that the Plan, amended and restated effective October 1, 2001, qualifies for deferred tax treatment of contributions under Section 401(k) of the Internal Revenue Code (“IRC”). Although the Plan has been amended since October 1, 2001, the Plan administrator and the Plan’s tax counsel believe that the Plan is designed and is currently being operated in compliance with the applicable requirements of the IRC.

(8) Other Income – Class Action Lawsuit Settlement
As trustee of the Plan, Fidelity purchases and sells shares of Southwest Gas Corporation stock on behalf of Plan participants. In February 2005, the Plan received $1,240,418 as a result of the settlement of a class action lawsuit in which Southwest Gas stockholders brought suit against the Company due to a failed merger. These funds were temporarily invested in the Fidelity Retirement Money Market Fund until November 2005, when these funds, along with allocable earnings, were distributed to affected Plan participants.
