Segment Information

The Company’s Chief Executive Officer has been identified as the chief operating decision maker (CODM). The CODM reviews the Company’s operating results on a consolidated basis for purposes of allocating resources and evaluating financial performance. Specifically, the CODM evaluates the Company’s financial performance and decides how to allocate resources based on consolidated net income (loss), which enables the CODM to assess both the overall level of resources available and optimize distribution of resources across functions, product lines, regions and research and development programs in line with our long-term corporate-wide strategic goals. The CODM also reviews disaggregated revenue by product line, geographic regions, and industry (see Note 3).

The following table presents entity-wide significant expense categories and net loss details provided to the CODM:
