Equity Method Investments and Joint Ventures [Abstract] |
Equity Investments | Equity Investments We have a 20% ownership interest in Independence Hub, LLC (“Independence Hub”) that we account for using the equity method of accounting. We previously had a 50% ownership interest in Deepwater Gateway, L.L.C., which we sold in February 2016 to a subsidiary of Genesis Energy, L.P., the other owner, for $25 million with no resulting gain or loss. We also received a cash distribution of $1.2 million from Deepwater Gateway in February 2016. Equity investments are included in our Production Facilities segment. Independence Hub owns the “Independence Hub” platform located in Mississippi Canyon Block 920 in a water depth of 8,000 feet. Our share of the losses reported by Independence Hub exceeded the carrying amount of our investment by $10.4 million as of March 31, 2017 and $10.2 million at December 31, 2016 reflecting our share of Independence Hub’s obligations (primarily its estimated asset retirement obligations to decommission the platform), net of remaining working capital. This liability is reflected in “Other non-current liabilities” in the accompanying condensed consolidated balance sheets.
