(1)

For the purpose of effective market monitoring by competent authorities, reference data for financial instruments should be reported in a consistent format and according to uniform standards.

(2)

Reporting and publication of reference data in electronic, machine-readable and downloadable form and format facilitates the efficient use and exchange of that data.

(3)

Promptly receiving reference data in respect of all financial instruments that are admitted to trading or that are traded on a trading venue or via a systematic internaliser, enables competent authorities and the European Securities and Markets Authority (ESMA) to ensure data quality and effective market monitoring and thus contributing to market integrity.

(4)

To ensure that trading venues and systematic internalisers submit complete and accurate reference data and that competent authorities are able to effectively receive and use such data in a timely manner, appropriate submission timelines should be established. Adequate time should be allowed to identify inaccuracies or incompleteness thereof prior to publication. To ensure that reference data submitted is consistent with the corresponding information reported in accordance with Article 26 of Regulation (EU) No 600/2014, reference data in respect of a given day should be used by competent authorities to validate and exchange the reports of transactions executed on that same day.

(5)

In accordance with Article 27(2) of Regulation (EU) No 600/2014, senders and recipients of reference data have to ensure the effective receipt, efficient exchange and quality of the data and its consistency with corresponding transaction reports provided in Article 26 of that Regulation. Trading venues and systematic internalisers should therefore provide complete and accurate reference data and should promptly inform competent authorities of identified incompleteness or inaccuracy in data already provided. They should also maintain adequate systems and controls for the purpose of accurate, complete and timely provision of reference data.

(6)

For the purposes of efficient use and exchange of reference data, and in order to ensure that reference data are consistent with corresponding data provided in transaction reports, trading venues and systematic internalisers must base the identification of financial instruments and legal entities to be included in the reference data on uniform accepted standards. In particular, and in order to ensure that reference data are matched with corresponding transaction reports, trading venues and systematic internalisers should ensure that International Securities Identifying Number codes in accordance with ISO 6166 pertaining to the financial instruments being reported are obtained and included in the reported data.

(7)

For reasons of consistency and in order to ensure the smooth functioning of the financial markets, it is necessary that the provisions laid down in this Regulation and the provisions laid down in Regulation (EU) No 600/2014 apply from the same date.

(8)

This Regulation is based on the draft regulatory technical standards submitted by ESMA to the Commission.

(9)

ESMA has conducted open public consultations on the draft regulatory technical standards on which this Regulation is based, analysed the potential related costs and benefits and requested the opinion of the Securities and Markets Stakeholder Group established by Article 37 of Regulation (EU) No 1095/2010 of the European Parliament and of the Council (2),
