	Domestic Coke		Coal Mining			Coal Logistics		Total

(1) As a result of the weakening coal market and the long-lived asset impairment relating to our Coal Mining segment, the Company performed a goodwill impairment analysis as of June 30, 2014 for the Coal Mining reporting unit. This analysis concluded that the fair value of the reporting unit, based on a discounted cash flows analysis, was less than the carrying amount. As a result, the Company recorded a $6.0 million pre-tax impairment of the entire goodwill balance. See Note 24.

(2) The Company acquired CMT during 2015 for total consideration of $403.1 million, of which $59.5 million was allocated to goodwill, representing the value of additional capacity and potential for future additional throughput. See Note 3.
