Segment Reporting [Abstract] |
Business Segment Information | Business Segment Information Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by a company's chief operating decision maker ("CODM"), or a decision making group, in deciding how to allocate resources and in assessing financial performance. As of December 31, 2016, the Company's CODM was the Company's CEO. The Company's operating and reportable segments are organized by products and services provided. As of December 31, 2016, the Company has two reportable segments: (1) Refined Coal ("RC"); and (2) Emissions Control ("EC"). The business segment measurements provided to and evaluated by the CODM are computed in accordance with the principles listed below:
• | The accounting policies of the operating segments are the same as those described in the summary of significant accounting policies except as described below.
• | Segment revenue includes the Company's equity method earnings and losses from the Company's equity method investments. Segment revenue also includes the Company's royalty earnings from Tinuum Group and income related to sales-type leases.
• | Segment operating income (loss) includes the Company's equity method earnings and losses from the Company's equity method investments, royalty earnings from Tinuum Group (including depreciation and amortization expense) and gains related to sales of equity method investments. However, segment operating income (loss) excludes Payroll and benefits, Rent and occupancy, Legal and professional fees, and General and administrative ("Corporate general and administrative expenses") unless otherwise specifically included, as the Company does not allocate those amounts between segments.
• | All items not included in operating income, except as noted below, are excluded from the RC and EC segments.
As of December 31, 2016 and December 31, 2015, substantially all of the Company's material assets are located in the U.S. and all significant customers are either U.S. companies or the U.S. Government. The following table presents the Company's operating segment results for the years ended December 31, 2016, 2015 and 2014:
