The relevant competent authority for one or more financial
instruments shall ensure that there is established and maintained
an updated list of those financial instruments. That list shall be
made available to the single competent authority designated as a
contact point by each Member State in accordance with
Article 56 of Directive 2004/39/EC. That list shall be made
available for the first time on the first trading day in June 2007.
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.
