Not reflected in the numbers below are indirect costs related to social investment, such as needs assessments and reimbursable expenses incurred by our in-country social investment personnel. All of the Social Investment Spend is for Kosmos-initiated projects, with the exception of the Jubilee Unit and TEN Development Project in Ghana and our non-operated share of the contractually obligated social investment for block 6 in São Tomé and Príncipe. Those values represent our participating interest in the social projects of our non-operated assets. Engaging with local fishing communities in Mauritania and Senegal is critical as we pursue the Greater Tortue Ahmeyim gas project. 1.
