In order to assist competent authorities to comply with the first subparagraph, each regulated market shall submit identifying reference data on each financial instrument admitted to trading in an electronic and standardised format to its home competent authority. This information shall be submitted for each financial instrument before trading commences in that particular instrument. The home competent authority shall ensure the data is transmitted to the relevant competent authority for the financial instrument concerned. The reference data shall be updated whenever there are changes to the data with respect to an instrument. The requirements in this subparagraph may be waived if the relevant competent authority for that financial instrument obtains the relevant reference data by other means.

(a) they ensure the security and confidentiality of the data reported;
