The research and valuation approach has been continuously developed and regularly adjusted over the past 25 years. The evaluation indicators are regularly checked for correctness and meaningfulness and it is ensured that the end product meets the requirements of neutrality and meets the highest industry standards.
The company profiles are continuously updated, whereby the core indicators of the sustainability analysis are updated at least once a year. Controversies that are also included in our valuation are updated weekly. Valuations of companies that are newly included in our benchmark indices are available at the latest three months after the company's entry into the index.
