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.
