On 2 January 2017, an amended version of Euronext Rule Book II, which includes rules specific to the Euronext Amsterdam market, entered into force. One significant change is that it is no longer required to discuss with Euronext an amendment to the articles of association of an issuer listed on Euronext Amsterdam. More generally, certain other provisions of the previous version of Rule Book II were deleted in light of its further harominsation with the harmonised Euronext rules.
On 6 March 2017, an amended version of Euronext Rule Book I, which includes harmonised rules across all Euronext markets, entered into force.
