2.5 Segment reporting
A business segment is a group of assets and operations engaged in providing products and services that are subject to risks and returns that differ from those of other business segments.
The Group’s business activities are categorised in three segments: Industrial Systems, Security Printing and Book Retailing. Other business activities include publishing as well as infrastructure services, which are not material in terms of their size. Information about the products and services of each business segment is provided in section 4.1 Notes to the consolidated financial statements.
