Investment opportunities are examined to what extent they violate the defined exclusion or negative criteria. If controversial business fields or controversy business practices are concerned, an investment is not permissible. In order to minimize systematic income risks, such as those arising from the exclusion of entire industries, negative criteria are only applied where, on the one hand, the definition of the criteria and, on the other hand, the data base on the investment options is clear. Those investment opportunities are selected on the basis of positive criteria (best-in-class approach) which make a significant contribution to sustainable economic activity and achieve their economic success taking into account social, ethical and ecological aspects. ESG criteria are used to identify exemplary companies, institutions, and countries that are at the forefront of the various dimensions of sustainability and excel in ecological, social, and economic action. Following the restriction of investment opportunities on the basis of the negative and best-in-class criteria, where appropriate finally the identification of opportunities is based on qualitative and quantitative financial and extra-financial factors relevant to performance. In addition, Engagement is an essential part of our strategy, focusing on impact investments.
