Segment Reporting [Abstract]  
Business Segments Business Segments
Our operating segments are: (i) Utility Coal Mining, (ii) Contract Mining and (iii) Minerals and Royalties. We determine our reportable segments by first identifying our 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. Our President and Chief Executive Officer, who is the Chief Operating Decision Maker (CODM), utilizes Operating profit (loss) to evaluate segment performance and allocate resources. Our CODM considers actual, budgeted and forecasted Operating profit (loss) from operations on a monthly basis for evaluating the performance of each segment and making decisions about allocating capital and other resources to each segment.

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.

See Note 1 for a discussion of our reportable segments. All current operations reside in the U.S.
The following table provides segment financial information and a reconciliation of segment results to consolidated results:
