Our chief operating decision maker (“CODM”) is our Chairman, President, and Chief Executive Officer. Our CODM is responsible for assessing the performance of the Company and each of our reportable segments as well as allocating resources, including personnel and capital resources. The measure of segment profit or loss utilized by our CODM is operating income. Our CODM evaluates segment performance by comparing historical, actual, and forecasted operating income on a regular basis. The accounting policies of our reportable segments are the same as those applied at the consolidated financial statement level as described in Note 2 - Summary of Significant Accounting Policies of the notes to consolidated financial statements.

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.
