The data represents drilling rigs as well as seismic and support vessels. In 2015, Kosmos did not operate any additional drilling in Ghana. We drilled exploration wells offshore Mauritania, completed an exploration well offshore Western Sahara, and began exploration drilling offshore Senegal. Waste and air emissions are measured in tons, with greenhouse gas emissions measured in metric tons of CO2 equivalent. The Payments to Governments data are reflective of direct payments made to government entities by Kosmos Energy on operated projects. Please see the footnotes below for further detail on the payments we made to our host country governments in 2015. PAYMENTS TO GOVERNMENTS (USD)1 1.  Our project-level disclosures are available on our website at www.kosmosenergy.com/responsibility/transparency.php. 2.  Represents payments made directly to government for satisfaction of training obligations per the Petroleum Sharing Contracts (PSCs). In addition to the numbers above, Kosmos made payments to third party training providers and/or national oil company employees in satisfaction of training obligations per the PSCs totaling $150,000 for Morocco. 3.  Primarily local payroll-related taxes and exclusive of withholding taxes remitted on behalf of vendors. 4. In addition to this, Kosmos Energy paid the U.S. government $24.1 million in income tax payments during 2015. 5.  Primarily relates to seismic data purchases from the government and fees associated with transfers of ownership interests 6.  Royalties represent the production entitlement to the Government of Ghana paid in barrels of oil out of Kosmos’ working interest share of production. Based on the annual average of daily Brent prices in 2015, this is worth approximately $23.6 million. 7.  Not reflected in the numbers above are payments to the port authority in Morocco primarily for leased use of port facilities in the amount of $500,000. *  N/R indicates metrics not reported in previous years.
