NOTE 1 - BASIS OF PRESENTATION:  

  The financial statements have been prepared by Southwest Gas Corporation
  (the Company) using the equity method of accounting for Northern Pipeline
  Construction Co.  This presentation is not in accordance with generally
  accepted accounting principles (GAAP), and certain information and footnote
  disclosures normally included in financial statements prepared in
  accordance with GAAP have been omitted.  The financial statement
  presentation in this report produces the same net income as the
  consolidated financial statements and, in management's opinion, is a fair
  representation of the operations and contributions to net income of the
  Company's operating segments.

NOTE 2 - DISCONTINUED OPERATIONS:

  In January 1996, Southwest Gas Corporation (the Company) reached an agreement 
  to sell PriMerit Bank (PriMerit) to Norwest Corporation.  Discontinued 
  operations includes the net income of PriMerit and its subsidiaries on a 
  stand-alone basis as adjusted, reduced by allocated carrying costs associated 
  with the Company's investment in PriMerit (principally interest) net of taxes.
  The discontinued operations also includes the estimated loss on the 
  disposition.  The sale of PriMerit to Norwest was completed in July 1996.
