INVESTMENTS—AFFILIATED COMPANIES

During 2013, we sold our equity interest in a bleach joint venture which resulted in a gain of $6.5 million. During both 2016 and 2015, we received $8.8 million as a result of the sale. As of December 31, 2016, all amounts have been collected under the sale arrangement.

On February 11, 2011, we acquired PolyOne’s 50% interest in SunBelt. With this acquisition, we agreed to a three-year earn out, which had no guaranteed minimum or maximum, based on the performance of SunBelt Chlor Alkali Partnership (SunBelt). For the year ended December 31, 2014, we paid the final payment of $26.7 million for the earn out related to the 2013 SunBelt performance. The earn out payment for 2014 included $14.8 million that was recognized as part of the original purchase price. The $14.8 million is included as a financing activity in the statement of cash flows.

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) 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.
