Materiality Identification Process
DHR and the Asset Manager use the following process for materiality identification in order to identify and assess the dependency on external stakeholders related to business activities, products and services, and their supply chains as well as the impact of the dependency.

Quantitative indicators related to key issues are used to assess the dependency and impact of DHR and the Asset Manager on stakeholders.
We have a system in place to review the materiality analysis annually and report to the Sustainability Committee, Compliance Committee, and Board of Directors of the Asset Manager, as well as to the Board of Directors of DHR.
We set KPIs, targets, or indicators (management items) related to materiality, and we monitor and disclose their progress every year. Our commitment is reinforced by linking the remuneration of the Executive Officer of DHR and the Board of Directors of the Asset Manager to the relevant targets or assessment indicators.
