The Chief Operating Decision Maker (“CODM”), i.e., The Board of Directors and the senior management, evaluate the Group’s performance and allocate resources to various strategic business units that are identified based on the products and services that they offer and on the basis of the market served. 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. Management believes that it is not practical to provide segment disclosure of these expenses and, accordingly, they are separately disclosed as “unallocated” and adjusted only against the total income of the Group.

A significant part of the Property, plant and equipment used in the Group’s business are not identifiable exclusively to any of the reportable segments and can be used interchangeably between segments. Management believes that it is not feasible to provide segment disclosures relating to total assets since a meaningful segregation of the available data is onerous.
