The scheduled maturities of debt related to the Facility are based on the level of borrowings and the estimated future available borrowing base as of December 31, 2016. Any increases or decreases in the level of borrowings or increases or decreases in the available borrowing base would impact the scheduled maturities of debt during the next five years and thereafter. As of December 31, 2016, there were no borrowings under the Corporate Revolver. (2) Based on outstanding borrowings as noted in (1) above and the LIBOR yield curves at the reporting date and commitment fees related to the Facility and Corporate Revolver and interest on the Senior Notes. (3) Primarily relates to corporate office and foreign office leases. (4) In January 2017, KEV exercised its option to cancel the fourth year and revert to the original day rate of approximately $0.6 million per day and original agreement end date of November 2017. Commitments calculated using the original day rate of $0.6 million effective February 1, 2017, excluding applicable taxes. The commitments also include a $48.1 million rate recovery payment equal to the difference between the original day rate and the amended day rate. (5) Does not include purchase commitments for jointly owned fields and facilities where we are not the operator and excludes commitments for exploration activities, including well commitments and seismic obligations, in our petroleum contracts. We currently have a commitment to drill two exploration wells in Mauritania. In Mauritania, our partner is obligated to fund our share of the cost of the exploration wells subject to their maximum $221 million cumulative exploration and appraisal carry covering both our Mauritania and Senegal blocks. Additionally, in Sao Tome and Principe we have 2D and 3D seismic requirements of 1,200 square kilometers and 4,000 square kilometers, respectively, and we have 3D seismic requirements in Mauritania and Western Sahara of 3,000 square kilometers and 5,000 square kilometers, respectively. The following table presents maturities by expected debt maturity dates, the weighted average interest rates expected to be paid on the Facility given current contractual terms and market conditions, and the debt’s estimated fair value. Weighted-average interest rates are based on implied forward rates 96
