Segments

Segment information is presented in accordance with ASC 280, Segment Reporting, which establishes standards for reporting information about operating segments. It also establishes standards for related disclosures about customers, products and geographic areas. Operating segments are defined as components of an enterprise that engage in business activities that earn revenues, incur expenses and prepare separate financial information that is evaluated regularly by the Company’s Chief Operating Decision Maker ("CODM") in order to allocate resources and assess performance. Resources are allocated and performance is assessed by the CODM.

Based on the provisions of ASC 280, the Company has defined its operating segment by considering management structure and product offerings. This evaluation resulted in one reportable segment.

As discussed in Note 3, Discontinued Operations, the Company closed the sale of the Disposed Business on November 1, 2018, which was previously reported as the Mechanical Insulation segment.

The Company’s continuing operations now consist of what was previously reported as the Specialty Building Products segment for the three and six months ended June 30, 2018.
