Our Health, Safety and Environmental (HSE) management system, The Standard, was reviewed and refreshed in 2015, a process we now conduct on an annual basis. The Standard sets clear expectations and performance measures that we use to plan and monitor our corporate, country and project-level activities. The Standard is available on our website at After license acquisition, the first stage in the oil and gas project lifecycle is the acquisition of seismic data. Kosmos recently completed seismic surveys offshore Mauritania and Senegal. Our geologists and geophysicists use the data to create detailed images of the earth’s physical characteristics which then enable us to make more informed decisions about the location of potential oil and gas deposits. Conducted offshore, our seismic activities also provide unique insight into the presence and abundance of marine life, including large mammals, birds, fish, corals, and others. Where possible, we share this data with scientists and local marine research institutes. For example, in Ireland, where we have relinquished our licenses in the Porcupine Basin, we are continuing to support the Marine Renewable Energy Ireland initiative by contributing marine ecological data sets developed during past seismic surveys to help researchers better understand and protect the marine ecology. Kosmos also supports a marine biodiversity initiative in Mauritania, the Biodiversity Oil and Gas Program, to improve understanding and protection of the Mauritanian offshore ecosystem. To read more about this program, see page 30. We always aim to promote the sustainable management of living natural resources and minimize the potential impact of our operations on the environment and biodiversity. We plan for an effective and timely response to emergencies that have the potential to impact personnel, the environment, local communities, or our assets. In 2015, we conducted regular global crisis simulation drills with internal and external stakeholders, such as governments and civil society. These types of exercises help us improve our ability to respond in the unlikely event of an emergency. Our local leadership team and HSES Advisors are mentored through these exercises to develop their ability to lead on the ground during an incident. In addition to training personnel, Kosmos carefully considers the technology and drilling equipment that we use. We base these decisions on our Well Integrity Management System (WIMS), which governs well design and the execution of drilling, completions and testing of wells. We believe in safe and efficient operations that are consistent with strong well governance procedures, and internationally recommended best practices. We believe climate change is real and influenced by human activity. At this time, Kosmos does not operate any of its producing assets. Kosmos’ only oil and gas production is offshore Ghana, where our co-venturer, Tullow Oil, operates the Jubilee field. While we do not participate in the Climate Disclosure Project (CDP), Tullow Oil participates in the CDP, reporting emissions and management processes on behalf of the Jubilee co- venturers, including Kosmos Energy. Our management will revisit this decision when Kosmos has operated oil or gas production. “Kosmos employees accept that the responsibility to ensure health, safety, and environmental protection is integral to the way we do business, not just because it’s a part of our social license to operate, but simply because it’s the right thing to do. It has become a core value that is demonstrated every day in the way we plan and execute our work and engage with our contractors and communities where we operate.” SCOTT BERGERON Senior Director, Health, Safety and Environment Kosmos Energy KOSMOS AND THE ENVIRONMENT PRINCIPLE BUSINESS 4 SAFETY PERFORMANCE Kosmos continued to improve safety performance in 2015 leading to the best year for safety in the company’s history. Key performance indicators for the year, available in the Performance Data on page 45, were based on industry benchmarks reported by the Oil and Gas Producers Association, as well as internal objectives for operational readiness and behavior-based training. In early 2016, Kosmos achieved a major milestone in our safety performance: one year of zero recordable incidents. Prior to achieving this milestone, we had two recordable incidents in January 2015: a wrist fracture at our shore base in Mauritania and a foot injury on the drillship. 11 11
