⁽¹⁾ We acquired an interest in Amberjack in the May 2018 Acquisition. The acquisition of this interest has been accounted for prospectively.

Unamortized differences in the basis of the initial investments and our interest in the separate net assets within the financial statements of the investees are amortized into net income over the remaining useful lives of the underlying assets. As of December 31, 2018, 2017 and 2016, the unamortized basis differences included in our equity investments are $40.4 million, $41.4 million and $42.7 million, respectively. For the years ended 2018, 2017 and 2016, the net amortization expense was $3.7 million, $3.8 million and $2.8 million, respectively, which is included in Income from equity method investments.

During the first quarter of 2018, the investment amount for Poseidon was reduced to zero due to distributions received that were in excess of our investment balance and we, therefore, suspended the equity method of accounting. As we have no commitments to provide further financial support to Poseidon, we have recorded excess distributions of $24.4 million in Other income for the year ended December 31, 2018. Once our cumulative share of equity earnings becomes greater than the amount of distributions received, we will resume the equity method of accounting as long as the equity method investment balance remains greater than zero.

⁽¹⁾We acquired an interest in Amberjack in the May 2018 Acquisition. The acquisition of this interest has been accounted for prospectively.

⁽³⁾ As stated above, the equity method of accounting has been suspended for Poseidon and excess distributions are recorded in Other income.

⁽⁴⁾ Included in Other is the activity associated with our investments in Permian Basin, LOCAP, Proteus and Endymion. We acquired a 41.48% interest in LOCAP in the December 2017 Acquisition. The acquisition of our ownership interests in Proteus and Endymion was effective in the December 2016 Acquisition, for which we were not entitled to a distribution and the related equity investment income was less than $0.1 million.

See Note 4 – Acquisitions and Divestiture for additional information regarding the acquisitions of our equity investments. We acquired an additional 22.0% interest in Odyssey on December 1, 2017, which is now being consolidated in our financial statements on a retrospective basis.

The adoption date of the new revenue standard for the majority of our equity method investments will follow the non-public business entity adoption date of January 1, 2019 for their stand-alone financial statements, with the exception of Mars and Permian Basin which adopted on January 1, 2018. As a result of adoption, we recognized our proportionate share of the Mars cumulative effect transition adjustment as a decrease to opening equity in the amount of $6.9 million under the modified retrospective transition method, related to its transportation and dedication agreements which resulted in a deferral of revenue. The cumulative effect transition adjustment for Permian Basin was not material.
