GRI Index [G4-20, G4-21, G4-32, G4-33]

This report is in accordance with the "core" option of the fourth generation (G4) guidelines of the Global Reporting Initiative (GRI). We report the appropriate GRI indicators for the aspects we consider material; reported indicators are not yet covered fully in some cases. We currently make no disclosures on certain indicators because we are still examining their relevance, there are currently no available data, or we do not report on them publicly for commercial or legal reasons. Indicators that apply to the media sector according to GRI are abbreviated with an M. The links to the Annual Report 2016 always refer to the start of the respective chapter in which the standard disclosures are presented.
