Segment Reporting [Abstract] |
Segment Reporting | NOTE 18 SEGMENT REPORTING In accordance with ASC 280, “Segment Reporting”, we define an operating segment as a business activity:
| ● | from which we may earn revenue and incur expenses;
| ● | whose operating results are regularly reviewed by the chief operating decision maker (“CODM”) to make decisions about resources to be allocated to the segment and assess its performance; and
| ● | for which discrete financial information is available.
We currently have three reporting segments, which include Treatment and Services Segments, which are based on a service offering approach; and Medical, whose primary purpose at this time is the R&D of a new medical isotope production technology. The Medical Segment has not generated any revenues and all costs incurred are reflected within R&D in the accompanying Consolidated Statements of Operations. As previously disclosed, the Medical Segment ceased a substantial portion of its R&D activities for the medical isotope production technology due to the need for substantial capital to fund such activities. Additionally, the Company is reviewing further strategic options for the Medical Segment. The Company does not anticipate that the Medical Segment will restart such activities until it obtains such funding. Our reporting segments exclude our corporate headquarter and our discontinued operations (see “Note 9 – Discontinued Operations”) which do not generate revenues. The table below shows certain financial information of our reporting segments as of and for the years ended December 31, 2018 and 2017 (in thousands).
