On May 11, 2018, we acquired SPLC’s ownership interests in Amberjack Pipeline Company LLC, a Delaware limited liability company (“Amberjack”), which is comprised of 75% of the issued and outstanding Series A membership interests of Amberjack and 50% of the issued and outstanding Series B membership interests of Amberjack for $1,220.0 million (the “May 2018 Acquisition”). The May 2018 Acquisition closed pursuant to a Purchase and Sale Agreement dated May 9, 2018 (the “May 2018 Purchase and Sale Agreement”) between us and SPLC, and is accounted for as a transaction between entities under common control on a prospective basis as an asset acquisition. We acquired historical carrying value of net assets under common control of $481.6 million which is included in Equity method investments in our consolidated balance sheet. We recognized $738.4 million of consideration in excess of the historical carrying value of net assets acquired as a capital distribution to our general partner in accordance with our policy for common control transactions. We funded the May 2018 Acquisition with $494.0 million in borrowings under our Five Year Revolver due July 2023 (as defined in Note 9—Related Party Debt) and $726.0 million in borrowings under our Five Year Revolver due December 2022 (as defined in Note 9—Related Party Debt).

During 2017, we completed three acquisitions, each as described below. Of these, the December 2017 Acquisition and the May 2017 Acquisition were considered transfers of businesses between entities under common control, and therefore the related acquired assets and liabilities were transferred at historical carrying value. Because these acquisitions were common control transactions in which we acquired businesses, our historical financial statements were recast for the periods of our Parent’s ownership prior to the transactions.

In connection with the May 2017 Purchase and Sale Agreement, we granted Shell Chemical a purchase option and right of first refusal with respect to Refinery Gas Pipeline and certain other related assets and the ownership interests in Sand Dollar. The purchase option may be triggered by, among other things, (i) a third party obtaining the right to use any or all of Refinery Gas Pipeline; (ii) the loss of all volume on Refinery Gas Pipeline that would result in it being permanently shutdown for two years or more; (iii) the termination of a transportation services agreement between Shell Chemical and Sand Dollar (“Refinery Gas Pipeline Agreement”); (iv) the expiration of the term of the Refinery Gas Pipeline Agreement; or (v) a change of control of our general partner; provided, however, that in the case of (i) through (iv), the purchase option would only be applicable to the Refinery Gas Pipeline impacted by such event. In addition, in the event that Sand Dollar receives an offer to sell all or a portion of Refinery Gas Pipeline or the ownership interests in Sand Dollar from a third party, Shell Chemical has a right of first refusal with respect to such Refinery Gas Pipeline or ownership interests, as applicable, for so long as the Refinery Gas Pipeline Agreement between Shell Chemical and Sand Dollar is in effect.
