1. For each securities settlement system it operates, a CSD shall establish a system that monitors settlement fails of transactions in financial instruments referred to in Article 5(1). It shall provide regular reports to the competent authority and relevant authorities, as to the number and details of settlement fails and any other relevant information, including the measures envisaged by CSDs and their participants to improve settlement efficiency. Those reports shall be made public by CSDs in an aggregated and anonymised form on an annual basis. The competent authorities shall share with ESMA any relevant information on settlement fails.
