(8)Regulation (EU) 2024/791 introduced into Article 2(1), point (16a), of Regulation (EU) No 600/2014 the definition of a ‘designated publishing entity’, and inserted into that Regulation a new Article 21a, which allows an investment firm that is a designated publishing entity to be responsible for making a transaction public through an approved publication arrangement (‘APA’). That same new Article 21a also specifies which party to a transaction should be responsible for making a transaction public where one, neither or both of the parties involved are designated publishing entities. It follows that the requirements laid down in Delegated Regulation (EU) 2017/583 that aim to identify the investment firm responsible for making a transaction public through an APA should be deleted.
