1. An application for registration or extension of registration shall be submitted in the format set out in the Annex.
2. The trade repository shall give a unique reference number to each document it submits and shall clearly identify which specific requirement in Delegated Regulation (EU) 2019/359 the document refers to.
3. An application for registration or extension of registration shall clearly indicate the reasons why information referring to a certain requirement is not submitted.
4. An application for registration or extension of registration shall be submitted in a durable medium meaning paper or any instrument which enables the recipient to store information addressed personally to him or her in a way accessible for future reference and for a period of time adequate for the purposes of the information and which allows the unchanged reproduction of the information stored. In particular, this covers floppy disks, CD-ROMs, DVDs and hard drives of personal computers on which electronic mail is stored, but it excludes internet sites, unless such sites meet the criteria specified in the first sentence of this paragraph. For the purposes of this term, the provision of information by means of electronic communications shall be treated as appropriate to the context in which the business between the firm and the client is, or is to be, carried on if there is evidence that the client has regular access to the internet. The provision by the client of an e-mail address for the purposes of the carrying on of that business is sufficient.
