Segment Reporting [Abstract]

Segment reporting

26. Segment reporting

The Company manages various types of business process and information technology services in an integrated manner for clients in various industries and geographic locations. The Company’s Chief Executive Officer, who has been identified as the Chief Operation Decision Maker (CODM), reviews financial information prepared on a consolidated basis, accompanied by disaggregated information about revenue and adjusted operating income by identified business units. The identified business units are organized for operational reasons and represent either services-based, customer-based, industry-based or geography-based units. There is significant overlap between the manner in which the business units are organized. Additionally, the composition and organization of the business units is fluid and the structure changes regularly in response to growth of the overall business, acquisitions and changes in the reporting structure, clients, services, industries served, and delivery centers.

Based on an overall evaluation of all facts and circumstances, and after combining operating segments with similar economic characteristics that comply with other aggregation criteria specified in the FASB guidance on segment reporting, the Company has determined that it operates as a single reportable segment.
