We own a 65 percent interest and Angco Cayman Limited (“Angco Cayman”) owns a 35 percent interest, in ADDCL, a variable interest entity (see Note 5—Variable Interest Entities). Angco Cayman has the right to require us to purchase its shares for cash. Accordingly, we present the carrying amount of Angco Cayman’s ownership interest as redeemable noncontrolling interest on our consolidated balance sheets. Noncontrolling interest Transocean Partners—On February 6, 2014, we formed Transocean Partners to own, operate and acquire modern, technologically advanced offshore drilling rigs. On August 5, 2014, we completed the initial public offering of 20.1 million common units of Transocean Partners. We retained the remaining 21.3 million common units, 27.6 million subordinated units, which collectively represented a 70.8 percent limited liability company interest, and all of the incentive distribution rights. In the year ended December 31, 2014, as a result of the offering, we received cash proceeds of $417 million, net of $26 million for underwriting discounts and commissions and other offering costs, and we recorded a capital allocation resulting in a decrease of $44 million to noncontrolling interest and a corresponding increase to additional paid‑in capital. In the years ended December 31, 2016, 2015 and 2014, Transocean Partners declared and paid an aggregate distribution of, $99 million, $100 million and $15 million, respectively, to its unitholders, of which $28 million, $29 million and $4 million, respectively, was paid to the holders of noncontrolling interest. On November 4, 2015, Transocean Partners announced that its board of directors approved a unit repurchase program, authorizing it to repurchase up to $40 million of its publicly held common units. Under the unit repurchase program, Transocean Partners repurchased 478,376 of its publicly held common units for an aggregate purchase price of $4 million and such repurchased common units were cancelled. On December 9, 2016, Transocean Partners completed a merger with one of our subsidiaries as contemplated under the Merger Agreement. Following the completion of the merger, Transocean Partners became a wholly owned indirect subsidiary of Transocean Ltd. Each Transocean Partners common unit that was issued and outstanding immediately prior to the closing, other than the units held by Transocean and its subsidiaries, was converted into the right to receive 1.20 of our shares. To complete the merger, we issued 23.8 million shares from conditional capital. TDSOI—In June 2016, we served notice of our intent to exercise our option to call the 30 percent ownership interest in TDSOI held by our local partner. In July 2016, we completed the repurchase of the noncontrolling interest for a cash payment of $2 million, and as a result, TDSOI became our wholly owned subsidiary. In connection with the transaction, we recorded a capital allocation resulting in a $12 million increase to noncontrolling interest and a corresponding decrease to additional paid in capital.
