S trong and supportive partnerships underpin our business and create value. Our stakeholders are interested or potentially affected parties, including shareholders, employees, governments, citizens of our host countries, communities, business partners and suppliers, and civil society. We believe we have a unique corporate responsibility with respect to each of these groups: SHAREHOLDERS We aim to create attractive returns and manage our business risks. Kosmos Energy’s board of directors focuses on building a successful, long-term future for the company and maintaining good corporate governance. At the end of 2018, the board was comprised of 6 members, including 4 independent directors. The board of directors has 4 standing committees: audit; nominating and corporate governance; compensation; and health, safety and environment. EMPLOYEES We aim to provide a stimulating and rewarding work environment through a culture that promotes entrepreneurial thinking, facilitates teamwork, and embraces ethical behavior. Directors, officers, and employees are required to comply with all aspects of the Business Principles and our Code of Conduct in their work activities and in representing the company. HOST GOVERNMENTS We seek to collaborate with host governments and contribute to national development. Our goal with host governments is to develop a shared agenda based on mutual trust and respect. We begin engaging with host governments at the time of licensing to ensure alignment with national priorities and industry needs. Kosmos aims to become a partner of choice. We are open about our business dealings with governments because transparency builds trust and accountability. We believe Kosmos is the only oil and gas company in the world to publish all of its contracts with host governments and we are the first U.S. oil and gas company to disclose project-level payments to governments. The “Performance Data” on page 65 of this report lists the payments we made to governments in 2018. COMMUNITIES We believe in engaging local communities in a manner that creates economic and social opportunity and respects human rights. Investing in community relationships ahead of drilling operations, during development projects, and during production operations is a key part of our approach. Our Stakeholder Engagement and Community Development Policy explains the standards to which we hold ourselves accountable when interacting with communities. We have published this policy on our website at: http://www. kosmosenergy.com/society-and- communities/. BUSINESS PARTNERS AND SUPPLIERS We allocate contracts through a fair and transparent process and adhere to our Business Principles in our operations. We aim to work with suppliers, both local and multi-national, who share our values and standards. We are committed to maintaining effective systems and procedures to prevent inhumane treatment and forced labor from taking place within our operations or our supply chain. Our employees and contractors are prohibited from engaging in improper payments and misusing confidential information to indulge in, or help others to participate in, insider trading. We expect our employees and contractors to respect confidential and proprietary information and we similarly work to protect the intellectual property of others. 8 9 CIVIL SOCIETY We will engage with and listen to civil society, recognizing the role civil society plays in holding governments and companies accountable. We are always open to having meaningful dialogue with civil society about the challenges inherent in exploring for oil and gas. Sometimes we will disagree, but we believe listening and engaging in debate deepens our understanding of the issues. We seek non- governmental organizations (NGOs) as valued partners in our social investment programs. Our relationships with civil society in the countries and communities where we work create mutual value and are central to our success. Kosmos also engages in public policy discussions occurring globally on energy and corporate responsibility. Kosmos has been a formal supporter of the United Nations Global Compact since 2013. The UN Global Compact is a voluntary initiative for businesses that are committed to aligning their operations and strategies with universal principles in the areas of human rights, labor, environment, and anti-corruption, and take actions that advance societal goals. Responsibilities to Stakeholders 1 BUSINESS PRINCIPLE We seek to maximize the amount of goods, services, and employment that we source locally. Our local content approach aims to enable people to access jobs, and to enable businesses to access supply chain opportunities through Kosmos. WE AIM TO PROVIDE A STIMULATING AND REWARDING WORK ENVIRONMENT THROUGH A CULTURE THAT PROMOTES ENTREPRENEURIAL THINKING, FACILITATES TEAMWORK, AND EMBRACES ETHICAL BEHAVIOR.
