Unconsolidated Affiliates
Unconsolidated Affiliates	Note 4—Unconsolidated Affiliates Investments—We hold investments in various partially owned, unconsolidated companies, the most significant of which is a 33.0 percent ownership interest in Orion Holdings (Cayman) Limited (together with its subsidiary, “Orion”), a Cayman Islands company that, through its wholly owned subsidiary, owns the harsh environment floater Transocean Norge. Additionally, we hold noncontrolling interests in certain companies that are involved in researching and developing technology to improve operational efficiency and reliability and to increase automation, sustainability and safety in drilling and other activities. In the six months ended June 30, 2020 and 2019, we made an aggregate cash contribution of $6 million and $59 million, respectively, to Orion. In the three months ended June 30, 2020, we recognized a loss of $59 million, which had no tax effect, recorded in other, net, associated with the impairment of our investment in Orion upon determination that the carrying amount of our equity-method investment exceeded the estimated fair value and that the impairment was other than temporary. We estimated the fair value of our investment using the income method, which required us to use significant unobservable inputs, representative of a Level 3 fair value measurement, including applying an assumed discount rate of 12 percent and making assumptions about the future performance of the investment, including future demand and supply for harsh environment floaters, rig utilization, revenue efficiency and dayrates. At June 30, 2020 and December 31, 2019, the aggregate carrying amount of our investment in Orion was $106 million and $164 million, respectively, recorded in other assets. Related party transactions—We engage in certain related party transactions with Orion under a management services agreement for the operation and maintenance of the harsh environment floater Transocean Norge and marketing services agreement for the marketing of the rig. Prior to the rig’s placement into service, we also engaged in certain related party transactions with Orion under a shipyard care agreement for the construction of the rig and other matters related to its completion and delivery. In the three and six months ended June 30, 2020, we received an aggregate cash payment of $26 million and $31 million, respectively, primarily related to the shipyard care agreement. In the three and six months ended June 30, 2019, we received an aggregate cash payment of $20 million and $33 million, respectively, primarily related to the commissioning, preparation and mobilization of Transocean Norge under the shipyard care agreement. We also lease the rig under a short-term bareboat charter agreement, which is currently expected to expire in March 2021.
