The measure of profit / loss reviewed by the CODM is “Earnings/loss before interest, taxes, depreciation and amortization” also referred to as “segment operating income / loss”. Revenue in relation to segments is categorized based on items that are individually identifiable to that segment.

Bandwidth costs, which form a significant part of the total expenses, is allocated to Network Services. Manpower costs of Technology resources rendering services to support Infrastructure operations, Managed services and Application services, are identified to respective operating segments specifically. The Group believes that the resulting allocations are reasonable.

Certain expenses, such as depreciation, technology infrastructure and administrative overheads, which form a significant component of total expenses, are not allocable to specific segments as the underlying services are used interchangeably.
