Regulation No 07/2001 is a set of rules issued by the Portuguese Securities Market Commission (CMVM) to promote good corporate governance practices among companies listed on the Portuguese stock exchange. The regulation covers topics such as board composition and functioning, remuneration, audit committees, and disclosure of information. The regulation is mandatory, and companies are required to comply with its provisions. The regulation aims to increase transparency, accountability, and shareholder value, and to promote investor confidence in the Portuguese market. The regulation has been updated several times since its introduction in 2001 to reflect changes in best practices and market conditions.
