The rules for companies listed on the Oslo Stock Exchange and other regulated markets impose high standards of transparency, market conduct and compliance with laws and regulations.
Disputes and sanctions may arise in connection with stocklistings, ongoing infdisclosureobligations, trading in shares or other securities, and in inspections by the Financial Supervisory Authority.
Examples of common stock exchange and securities law disputes include:
- Questions regarding when information constitutes inside information and when a stock exchange announcement must be made
- Disagreement as to whether there has been a breach of the rules on market abuse, such as illegal insider trading or market manipulation
- Complaints or disputes relating to the imposition of administrative fines or other sanctions by the Financial Supervisory Authority or the stock exchange authorities
- Claims for damages from investors arising from alleged breaches of disclosure obligations and other securities regulations.
