NOTE 1 - BASIS OF PRESENTATION:

  The financial statements have been prepared by Southwest Gas Corporation
  (the Company) using the equity method of accounting for its construction
  services subsidiary.  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, 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.  Discontinued
  operations also includes the estimated loss on the disposition.  The sale
  of PriMerit to Norwest was completed in July 1996.
