Invitation to the ESMA European Single Electronic Format Meet-the-Market Workshop

Date: Tuesday 6 June 2017 Programme and description

Venue: ECB Headquarters, Sonnemannstrasse 20, 60314 Frankfurt am Main, Germany

Background information

The European Securities and Markets Authority (ESMA) was empowered by Article 4(7) of the Amended Transparency Directive to draft a regulatory technical standard (RTS) specifying an European Single Electronic Format (ESEF) in which annual financial reports have to be prepared.

After carrying out a consultation, ESMA published a Feedback Statement in which it sets out the main decisions taken. These can be summarised as follows:

  • All annual financial reports will have to be prepared in XHTML;

  • Where the annual financial report contains IFRS consolidated financial statements, they have to be marked-up with XBRL tags according to the IFRS Taxonomy;

  • The XBRL tags have to be embedded in the XHTML document through the Inline XBRL technology.

    ESMA is in the process of developing the detailed rules to be specified in the RTS including:

  • a regulatory XBRL extension taxonomy,

  • rules that guide how the XBRL tags shall be applied and

  • other rules that provide guidance on the preparation and filing of filings in XBRL format (filing rules).

As part of the proposed RTS consultation ESMA is soliciting feedback from wide group of stakeholders affected by the planned rules.

The European Securities Markets Authority and the European Single Electronic Format (ESEF) Task Force (consisting mainly of representatives from European National Competent Authorities), supported by the Business Reporting - Advisory Group, (technical advisors to the ESEF project), therefore invite all interested parties to this workshop to provide further details on and enable discussion about the planned detailed technical specifications.


The objective of the workshop is to inform participants about the current considerations regarding the detailed technical specifications as well as to provide them with an opportunity to comment on the working draft of the regulatory extension taxonomy and the filing rules. Furthermore, ESMA would like to explore whether some of the participants would be interested to participate in a field test exercise.
