GRI Index

The GRI index and other sections of the Annual and Sustainability Report have been prepared according to GRI G4 “In accordance – Core.” Additionally we use the Telecommunications Sector Supplement. Deloitte has been engaged to provide a limited level of assurance on these sections, see Auditors’ Limited Assurance Report on the Sustainability Report for more information. All disclosures in this GRI index are covered by the limited assurance engagement. In the case of a disclosure not being fully reported, the omission is explained at the end of the disclosure.
