INTERVIEW “We stand for reliability”
On 5 December 2016, the Board of Trustees extended the terms of office of the RAG-Stiftung’s Board of Executives members for a further five years start- ing in December 2017. So this is a good time for retrospectives, insights and forecasts. Dr. Werner Müller, Bärbel Bergerhoff-Wodopia and Dr. Helmut Linssen shared their insights with the Hamburg-based journalist Oliver Driesen.

And, false modesty aside, we have in fact been quite successful. We’ve generated good returns during difficult times for investors—that’s a feat that shouldn’t be taken for granted. Our Board of Trustees apparently shares this view and “One central conclusion of trusts us to continue along this course. our study of the future Ms. Bergerhoff-Wodopia, it seems that the of the Ruhr region is that sponsors of the many educational, scientific and cultural projects that the foundation we have to strongly supports are also glad that you will continue to enhance the attractiveness serve as the member of the Board of Executives responsible for such projects beyond 2017. of this region.” Bärbel Bergerhoff-Wodopia: That’s understanda- DR.
