Equity Method Investments and Joint Ventures [Abstract] |
INVESTMENTS-AFFILIATED COMPANIES | INVESTMENTS—AFFILIATED COMPANIES Prior to the acquisition of SunBelt, we held a 50% ownership interest, which was accounted for using the equity method of accounting. On November 16, 2007, we purchased for cash an $11.6 million equity interest in a bleach joint venture. As part of the investment we also entered into several commercial agreements, including agreements by which we would supply raw materials and services, and we would have marketing responsibility for bleach and caustic soda. During 2013, we sold our equity interest in the bleach joint venture which resulted in a gain of $6.5 million. As a result of the sale, as of December 31, 2013, we have recorded a long-term receivable of $15.6 million which is included within other assets on our consolidated balance sheet. We hold a 9.1% limited partnership interest in Bay Gas Storage Company, Ltd. (Bay Gas), an Alabama limited partnership, in which EnergySouth, Inc. (EnergySouth), which was acquired in 2008 by Sempra Energy, is the general partner with interest of 90.9%. Bay Gas owns, leases and operates underground gas storage and related pipeline facilities, which are used to provide storage in the McIntosh, AL area and delivery of natural gas to EnergySouth customers.
