14. SEGMENT INFORMATION

Segment information is based on a management approach, which requires segmentation based upon the Company’s internal organization and reporting. The Company’s operations for the three months ended March 31, 2018 were classified into five reporting segments: Coal - U.S., Coal - Canada, Coal - WMLP, Heritage and Corporate. The Company's operations for the three months ended March 31, 2017 included the aforementioned reporting segments as well as our previously existing Power segment, however, during the fourth quarter of 2017 we sold all of the assets that comprised this Power operating segment and terminated all related power agreements.
