The European Securities and Markets Authority (ESMA) has today updated its Questions and Answers (Q&As) on data reporting under the Market in Financial Instruments Regulation (MiFIR).

The Q&As provide clarifications in relation to the requirements for submission of transaction reports and reference data under MiFIR. In particular, the Q&As relate to Complex Trades and National client identifiers for natural persons.

The Q&A on complex trades provides new answers on reporting transactions and reference data for instruments where the execution results in a complex trade as defined under Article 12 of RTS 22.

The amendments to the existing Q&A on national client identifiers for natural persons further clarify how the following three national identifiers specified in Annex II of RTS 22 should be represented: the Czech ID, the Liechtensteinian ID, and the Romanian ID.

The purpose of this Q&A is to promote common supervisory approaches and practices in the application of MiFIR. It provides guidance to Investment Firms, Trading Venues, ARMs and Systematic Internalisers on compliance with the reporting provisions of MiFIR.

ESMA will periodically review these Q&A and update them where required.
