Segment Reporting Disclosure Segment Reporting
The Company has one reportable segment. The Company’s chief operating decision maker is the Chief Executive Officer and President. The accounting policies of the single segment are the same as those described in the summary of significant accounting policies. The chief operating decision maker assesses performance for the single segment and decides how to allocate resources based on net income (loss) that also is reported on the condensed consolidated statements of operations and comprehensive income (loss) as consolidated net income (loss). The chief operating decision maker uses net income (loss) to monitor budget versus actual results and to evaluate the overall cash burn of the business.
