Segment Reporting [Abstract]

Business Segments

Business Segments

The Company’s operating segments are: (i) Coal Mining, (ii) NAMining and (iii) Minerals Management. 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 has items not directly attributable to a reportable segment that are not included as part of the measurement of segment operating profit. These items primarily include administrative costs related to public company reporting requirements at the parent company and the financial results of Mitigation Resources and Bellaire. Mitigation Resources 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.

All financial statement line items below operating profit (other income including interest expense and interest income, the provision (benefit) for income taxes and net income) are presented and discussed within this Form 10-Q on a consolidated basis.

The following table presents Revenues, Cost of sales, Earnings of unconsolidated operations, Operating expenses, Operating profit (loss), Expenditures for property, plant and equipment and acquisition of mineral interests and Depreciation, depletion and amortization expense:
