SEGMENT REPORTING

(14) SEGMENT REPORTING

At December 31, 2011, the Company has three wholly-owned subsidiaries; Zynex Medical (ZMI), Zynex NeuroDiagnostics (ZND), and Zynex Monitoring Solutions (ZMS). The Company has determined that these subsidiaries (ZMI, ZND, and ZMS) each represent reporting segments. This determination was made based on the nature of the products and services offered to customers or the nature of the function in the organization. Prior to the fourth quarter of 2011, the operations of ZND and ZMS were not considered material for segment presentation. Although the segment reporting for the fiscal year ended December 31, 2010 was not material to the financial statement presentation, it is included herein for comparative purpose.

The accounting policies for each of these segments are the same as those described in Note 1, and inter-segment transactions are eliminated. Net revenue was primarily generated from sales in the United States. The tables below summarize information about reported segments (in thousands), for 2011 and 2010.
