16. SEGMENT AND GEOGRAPHIC INFORMATION
The Company is the global leader and pioneer in developing NAND flash controllers for solid state storage devices. The Company currently operates as one
reportable segment. The Chief Operating Decision Maker (“CODM”) is the Chief Executive Officer, who is directly involved in the Company’s operations and product development. The CODM is ultimately responsible for and actively involved in the allocation of resources and the assessment of the Company’s performance using consolidated net income reported on the consolidated statements of income, supplemented by revenue information disaggregated by geographic region and target customers. The measure of segment assets is reported on the consolidated balance sheet as total assets. The CODM uses consolidated net income to evaluate income generated in determining whether to reinvest profits in
 
the segment or to deploy such profits for other purposes, such as acquisitions or share repurchases. Net income is also used to monitor budgeted results compared to actual performance. In addition, the CODM uses consolidated net income in competitive analyses by benchmarking the segment’s performance against that of the Company’s competitors. These competitive analyses, together with comparisons of budgeted and actual results, are used in assessing segment performance and in determining management and variable compensation. The Company’s organizational structure is functionally aligned with department heads and shared resources reporting directly to the CODM. The Company employs a highly integrated product development approach, with proprietary technologies utilized across multiple products and substantially all integrated circuits manufactured using similar processes. As a result, the Company operates as a single operating segment.
The following table presents selected financial information, including significant expenses and other expense information provided to CODM, with respect to the Company’s
single
operating segment for the years ended December 31, 2023, 2024 and 2025:
