(5)Since multiple pieces of inside information can exist within an entity at the same time, the insider lists referred to in Article 18(1) and (6), second subparagraph, of Regulation (EU) No 596/2014 should identify the exact piece of inside information to which the persons referred to in Article 18(1) of Regulation (EU) No 596/2014 have access. To that end, those insider lists should contain a section specific to each piece of inside information (the ‘event-based section’). Each event-based section should list all persons having access to a specific piece of inside information and, for each person, indicate the date and time when the insider obtained access to that piece of inside information and the date and time when the insider ceased to have access to that piece of inside information. A new section should be added to the insider lists referred to in Article 18(1) and (6), second subparagraph, of Regulation (EU) No 596/2014 upon the identification of a new piece of inside information.
