Item 7.01 Regulation FD Disclosure
In the fourth quarter of 2012, the Public Utilities Commission of Nevada (“Commission”) issued an order dated November 6, 2012 (the “Order”) in the Nevada general rate case application (Docket Nos. 12-02019 and 12-04005) filed by Southwest Gas Corporation (“Southwest”) in April 2012. The Commission’s Order employed alternative capital structures for northern and southern Nevada instead of the actual capital structure of Southwest that was supported by all parties. The revenue increases of $5.8 million in southern Nevada and $1.2 million in northern Nevada provided by the Order were based on a 9.85% return on 42.6% common equity in southern Nevada and a 9.20% return on 65.6% common equity in northern Nevada. A rehearing related to the capital structure was held in January 2013, and the parties to the proceeding presented evidence in support of their respective positions on what capital structure the Commission should utilize in establishing rates.
On March 14, 2013, the Commission reached a decision (the “Decision”) in the rehearing relating to the capital structure issue. The Decision retained an alternative capital structure and authorized a 10.0% return on 42.7% common equity in southern Nevada and a 9.30% return on 59.1% common equity in northern Nevada. When compared to the original Order, the Decision is expected to result in an incremental annual revenue increase of $1.0 million in southern Nevada and an incremental annual revenue decrease of $0.5 million in northern Nevada.
