(4)Article 21a of Regulation (EU) 2017/1129 requires competent authorities to build, to the extent possible, on the mechanisms implemented for the purposes of Article 25(6) of that Regulation for making the information referred to in Article 21a(1) thereof accessible on the European Single Access Point (ESAP). To minimise the compliance burden on both competent authorities and issuers, the obligation to make the information referred to in Article 21a(1) of Regulation (EU) 2017/1129 accessible on ESAP may be fulfilled by making such information available to ESMA via the notification portal referred to in Article 25(6) of that Regulation. The notification portal is to be used to submit the information referred to in Article 21(1) of Regulation (EU) 2017/1129 in accordance with Article 21(5) of that Regulation and any additional information required by Article 21a thereof that is not currently in the scope of the storage mechanism referred to in Article 21(6) of Regulation (EU) 2017/1129, accompanied by the relevant metadata. Delegated Regulation (EU) 2019/979 should be updated to reflect those changes.
