The information obligation also extends to the legal relations of the Company to an affiliated company and to the state of the Group and of the companies included in the Consolidated Financial Statements. Information may be denied if, according to reasonable business judgement, it could cause significant harm to the Company or an affiliated company, or if the disclosure thereof would constitute an offence.
