Segment Reporting [Abstract]

BUSINESS SEGMENT INFORMATION

BUSINESS SEGMENT INFORMATION

Segment information is based on a management approach, which requires segmentation based upon the Company’s internal organization, reporting of revenue, and operating income.

The Company’s operations are classified into four reporting segments: coal, power, heritage and corporate. The coal reporting segment includes the aggregated operations of coal mines located in Wyoming, Montana, North Dakota and Texas. The power segment includes its ROVA operations located in North Carolina. The heritage segment costs primarily include benefits the Company provides to former mining operation employees as well as other administrative costs associated with providing those benefits and cost containment efforts. The corporate segment primarily consists of corporate administrative expenses.

Summarized financial information by segment is as follows:
