ITEM 5.  OTHER EVENTS

The following table sets forth the ratios of earnings to fixed charges for
(a) the continuing operations of Southwest Gas Corporation (the Company) and
(b) the continuing operations of the Company adjusted for interest allocated
to the discontinued operations of PriMerit Bank.

FOR THE TWELVE FOR THE YEAR ENDED DECEMBER 31, MONTHS ENDED ---------------------------------------- SEPTEMBER 30, 1996 1995 1994 1993 1992 1991 ------------------ ---- ---- ---- ---- ---- Ratios of earnings to fixed charges (1): Continuing operations (2) 1.06 1.69 1.47 2.21 1.70 Adjusted for interest allocated to discontinued operations (2) 1.05 1.61 1.40 2.03 1.61
- ----------- (1) For purposes of computing the ratios of earnings to fixed charges, earnings are defined as the sum of pretax income from continuing operations plus fixed charges. Fixed charges consist of all interest expense including capitalized interest, preferred securities distributions, one-third of rent expense (which approximates the interest component of such expense), and amortized debt expense. (2) For the twelve months ended September 30, 1996, pretax earnings from continuing operations were insufficient to cover fixed charges by $784,000. This was primarily due to the record warm temperatures experienced throughout the Company's service areas during the 1995/1996 heating season. ITEM 7. EXHIBITS 12.01 Computation of Ratios of Earnings to Fixed Charges. SIGNATURES Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
