The Financial Supervisory Authority monitors listed companies’ and other securities issuers’ ongoing and regular disclosure requirements, compliance with IFRS financial statement requirements and companies’ insider trading.

The majority of our work is proactive supervision with emphasis on promotion of good market practices and methods in order to maintain market efficiency and investor confidence.

Our supervision is also reactive, focusing on cases of suspected market abuse, such as the abuse of insider information, market manipulation and breach of disclosure obligations.
