Segment Reporting and Disaggregation of Relevant Expense Captions
The Company manages its operations as a single segment for the purposes of assessing performance and making operating decisions. The determination of a single business segment is consistent with the consolidated financial information periodically reviewed by the Chief Executive Officer as chief operation decision maker ("CODM") in assessing segment performance and deciding how to allocate resources.

The CODM uses net income or loss to monitor budgets, forecasts and expected cash flows in assessing segment performance and in deciding how to allocate resources. The measure of segment assets is reported on the consolidated balance sheets as total assets.
The following table presents information about reported significant segment expenses and net loss (in thousands):

About Segments Disclosures

Segment disclosures break a company into its reportable operating units, revealing revenue, profit, and asset allocation that consolidated financial statements obscure. Under ASC 280, segments must match how the chief operating decision maker views the business, providing a window into internal management structure and resource allocation priorities.

Key signals: compare segment margins to identify which units drive profitability and which destroy value. Watch for changes in the number of reportable segments — segment aggregation or disaggregation often coincides with strategic shifts or attempts to obscure declining performance. Intersegment elimination patterns reveal internal pricing practices. The reconciliation between segment totals and consolidated figures exposes corporate overhead allocation and unallocated items. Geographic revenue concentration highlights regulatory and currency exposure. Compare segment-level capital expenditure against segment revenue to assess where management is investing for future growth versus harvesting existing assets.
