Waste and air emissions are measured in tons, with greenhouse gas emissions measured in metric tons of CO2 equivalent. The data represents drilling rigs as well as seismic and support vessels. In 2016, Kosmos did not operate any drilling in Ghana. We drilled exploration wells offshore Mauritania and Senegal and conducted seismic surveys offshore Mauritania, Senegal and Suriname. The Atwood Achiever drillship sat offshore Mauritania during a pause period from June through December 2016. The Payments to Government 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 2016. 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 Agreements and/or Petroleum Sharing Contracts (PSCs), as applicable. In addition to the numbers above, Kosmos made payments to third party training providers and/or national oil company employees in accordance with training obligations per the PSCs totaling $1.0 million for Morocco. 3.  Primarily local payroll-related taxes and withholding taxes on interest payments in Ghana. These values are exclusive of withholding taxes remitted on behalf of service providers. 4. In addition to this, Kosmos Energy paid the U.S. government $11.7 million in income tax payments during 2016. 5.  Primarily relates to costs associated with withdrawing from the Tarhazoute Offshore Area of Interest in Morocco. 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 2016, this is worth approximately $16.2 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 $75,000. 1.  N/R indicates metrics not reported in previous years. We reported on new metrics as a result of materiality discussions, benchmarking, and improved reporting processes.
