Segment reporting
Operating segments, and the amounts of each segment item reported in the financial statements, are identified from the financial information provided regularly to the Group’s chief operating decision maker for the purposes of allocating resources to, and assessing the performance of, the Group’s various lines of business and geographical locations.
Individually material operating segments are not aggregated for financial reporting purposes unless the segments have similar economic characteristics and are similar in respect of the nature of products and services, the nature of production processes, the type or class of customers, the methods used to distribute the products or provide the services, and the nature of the regulatory environment. Operating segments which are not individually material may be aggregated if they share a majority of these criteria.
