(1) Includes undiscounted port take-or-pay commitments as agreed to in the fourth quarter of 2016 for 2017-2018. The new agreement does not contain any commitments subsequent to the end of 2018, unless we elect to exercise an option to extend the agreement through 2019. We have the right to terminate our commitments for 2017 and 2018 at any time in exchange for a buyout payment. All prior agreements, including the previous take-or-pay commitments through 2024, have been terminated. These amounts when paid under the new agreement are considered minimum payments on services. The per tonne loading charges through 2018 reflect these advance payments.

(2) Includes undiscounted rail take-or-pay commitments as agreed to in February 2017 and effective April 1, 2017. The new agreement does not contain any commitments subsequent to the end of 2018, unless the parties agree to extend the agreement. We have the right to terminate our commitments for 2017 and 2018 at any time in exchange for a buyout payment. If we do not meet the required portion of our future nominated tons, there would be incremental liquidated damages due under the new agreement. Activity during the period includes decreases for payments made partially offset by the impact of nominations, which have potential future liquidated damages if we do not ship the nominated tons through 2017. All prior agreements, including the previous take-or-pay commitments through 2024, have been terminated.
