(5)To carry out their duties effectively and consistently, the authorities authorised to have access to the records of CSDs in accordance with Regulation (EU) No 909/2014 should be provided with data that is comparable across CSDs. In addition, the use of common formats across different financial market infrastructures should facilitate the greater use of those formats by a wide variety of market participants, thus promoting standardisation. Standardised procedures and data formats across CSDs should reduce as well the costs for market participants and facilitate the tasks of supervisors and regulators.
