(1) Adjusted cost of revenues is a significant expense category, and amounts align with the segment-level information that is regularly provided to the CODM. Adjusted cost of revenues is defined by management as cost of revenues adjusted for purchase accounting impacts and excluding depreciation, amortization, and other segment expenses identified as non-operating by management.
(2) Other segment items included in segment income (loss) from operations for each segment include research and development expenses; selling and marketing expenses; general and administrative expenses; and any amounts excluded from cost of revenues to determine adjusted costs of revenues (e.g., depreciation, amortization, and other segment expenses identified as non-operating by management).
(3)Other loss consists of research and development expenses; selling and marketing expenses; and general and administrative expenses not allocated to the segments.
