Materiality analysis

The results of the internally conducted materiality analysis were reviewed and approved by the external stakeholder panel in September 2016. Following an internal review, no changes to the material aspects were carried out for reporting on the 2017 financial year. A further review of materiality is planned for the next reporting cycle as part of the switchover to the GRI Standards. The results are shown in the following dynamic chart. Material aspects are deemed material if they are significant from the internal perspective of the company or the external perspective of stakeholders. The aspects were divided into four categories: most material, material, less material and not material or not requiring any action.
