In 2017, Kosmos and its partner Trident Energy acquired Hess Corporation’s interests in the oil-producing Ceiba and Okume fields (Block G) and signed three new exploration licenses for offshore blocks W, S, and EG-21. Kosmos has also since acquired offshore block EG-24. The national oil company, GEPetrol, also owns interests in the fields and blocks. 23 K osmos is the operator of blocks W, S, EG-21, and EG- 24. A joint venture company, Kosmos Trident Equatorial Guinea Incorporated (KTEGI), was the operator of the Ceiba and Okume production assets throughout 2018, leveraging the distinct expertise of each company, combining Kosmos’ exploration and subsurface expertise with Trident’s operational capabilities. At year-end 2018, the joint venture was ended and Kosmos now retains a direct 40% interest in Block G. HUMAN RIGHTS DUE DILIGENCE AND TRAINING In keeping with regular practice, Kosmos engaged a third-party expert to conduct human rights due diligence for our anticipated in-country activities ahead of entering Equatorial Guinea. The report stressed the importance of community engagement, as well as policy implementation and monitoring. From the beginning of our investment, KTEGI adopted the Kosmos Business Principles, Anti- Corruption Policy, and Code of Conduct. In 2018, we conducted training for all employees on implementation of these policies, including human rights training for all KTEGI staff, with an emphasis on labor rights, the supply chain, community engagement, and grievance mechanisms. We have conducted similar training in other countries where we operate. For more information on our supply chain policies, please see page 19. We also established an employee whistleblower mechanism and conducted company-wide training on the aim, accessibility, and confidentiality of the mechanism. The mechanism has been extended to key contractors so their employees can also use it to report confidentially any concerns related to our operations. Finally, as is our practice, we conducted a security risk assessment for our operations in Equatorial Guinea, integrating the Voluntary Principles on Security and Human Rights. COMMUNITY ENGAGEMENT In 2018, Kosmos completed a 3D seismic survey across blocks W, S EG-21, and EG-24. Before the survey began, we conducted a thorough Environmental Impact Assessment (EIA) and engaged with fishing communities to provide information on the purpose of the survey, the vessel that would be conducting the work and the importance of safety around it, and to hear about any concerns regarding our planned activities. The EIA process included public meetings in the districts of Bata and Mbini, which were attended by more than 150 fishing community representatives. Kosmos established a community grievance mechanism so that members of the community could contact the company or the seismic vessel with any concerns once operations began. We also trained and hired four Equatoguineans to work as Fishing Liaison Officers (FLOs) on board the seismic vessel to engage with any fishing boats encountered offshore. Eleven government representatives were also trained in offshore safety to be able to participate in, and observe, the survey. During the seismic survey, Marine Mammal Observers (MMOs) on the vessel noted the presence of Humpback whales in the vicinity. The extent of the presence of whales was unexpected, and after extensive discussions with the onboard MMOs regarding how to respond to the situation, the decision was made to restrict certain operations to daylight hours and expand the mitigation zone, followed by a move to a different part of the planned survey area away from the whales.
