SEGMENT REPORTING |
SEGMENT REPORTING | 14. SEGMENT REPORTING ​ The Company’s chief operating decision maker (CODM) is its Chief Executive Officer. The Company has no segment managers who are held accountable by the CODM for operations, operating results, and planning for levels or components below the consolidated unit level. Accordingly, the Company has determined it has a single operating segment. ​ The CODM uses consolidated net loss for purposes of allocating resources and assessing segment performance, including monitoring actual results versus historical periods. Cost of revenue and operating expenses are considered significant segment expenses that are regularly provided to the CODM and included within consolidated net loss. The measure of segment assets is the total assets on the Company’s consolidated balance sheets. Capital expenditures are reported on a consolidated basis on the Company’s consolidated statements of cash flows. The following table includes the Company's segment revenue, significant segment expenses, and other segment items to reconcile to net loss. ​ ​
