Segment Reporting [Abstract]  
Business Segments Business Segments
The Company's operating segments are: (i) Coal Mining, (ii) NAMining and (iii) Minerals Management. While the Company continues to pursue opportunities to add new coal mining operations to the Coal Mining segment, the NAMining segment serves as the platform for pursuing non-coal mining projects and the Minerals Management segment promotes the development of the Company's gas, oil and coal reserves.
The Company determines its reportable segments by first identifying its operating segments, and then by assessing whether any components of these segments constitute a business for which discrete financial information is available and where segment management regularly reviews the operating results of that component. The Company’s Chief Operating Decision Maker utilizes operating profit to evaluate segment performance and allocate resources.
The Company also has unallocated items not directly attributable to a reportable segment which are not included as part of the measurement of segment operating profit, primarily administrative costs related to public company reporting requirements, the financial results of the Company’s mitigation banking business, Mitigation Resources of North America® (“MRNA”), and Bellaire. MRNA generates and sells stream and wetland mitigation credits (known as mitigation banking) and provides services to those engaged in permittee-responsible stream and wetland mitigation. Bellaire manages the Company’s long-term liabilities related to former Eastern U.S. underground mining activities. Transactions between segments are accounted for as third-party arrangements for purposes of presenting segment results of operations and are eliminated in consolidation.
As of January 1, 2020, the Company retrospectively changed its computation of segment operating profit to reclassify certain expenses, primarily related to executive and board compensation. These expenses are now included in unallocated items. The change in segment reporting reflected a decision to evaluate the financial performance of the Company’s segments excluding executive and board compensation. All prior period segment information has been reclassified to conform to the new presentation. This segment reporting change has no impact on consolidated operating results.

All financial statement line items below operating profit (other income including interest expense and interest income, the provision for income taxes and net income) are presented and discussed within this Form 10-Q on a consolidated basis. Included within other income on the line Income from other unconsolidated affiliates within the Unaudited Condensed Consolidated Statements of Operations is the financial results of NoDak Energy Services, LLC ("NoDak"). NoDak operated and maintained a coal drying system at a customer’s power plant. The NoDak contract expired in the first quarter of 2020.
