As the Company operates as one operating segment, all required segment financial information, such as revenues and significant operating expenses, is found in the accompanying unaudited interim condensed consolidated financial statements. For the periods presented, all of the Company’s long-lived assets were located in the United States, and all revenues from leasing of ASSURE© System devices to patients were earned in the United States. The accounting policies for segment reporting are the same as for the Company as a whole. | |
