Kosmos Energy was founded with the goal of creating value for all of our stakeholders: investors, employees, and the governments and citizens of our host countries. We recognize that creating steady, long-term returns can only be achieved by advancing the societies in which we work. In 2013, we adopted the Kosmos Energy Business Principles to formalize this commitment by articulating the values that have always guided our actions. The Business Principles are also informed by what our stakeholders have told us about their expectations of a responsible company. We define how we conduct our business and the standards to which we hold ourselves accountable through the Business Principles. The Business Principles are supported by more detailed policies, procedures, and management systems which are referenced in this report and on our website. The Business Principles reflect our values across six areas: Responsibilities to Stakeholders, Ethical Conduct, Our Workplaces, the Environment, Society, and Commercial Relationships. Although the Business Principles are our standard, the actions we take to adhere to them change as we evolve as a company. For each Principle, we have included a case study to demonstrate how we translated the words into action in 2017. THE KOSMOS ENERGY BUSINESS PRINCIPLES
