ESEF – European Single Electronic Format for listed companies starting with financial statements for 2021 (*)
(*) The wording of the Transparency directive has been changed so that application of ESEF is mandatory, starting from the financial year beginning on or after January 1st 2021. In Finland, the change of the directive has been implemented in the Securities Markets Act by making changes to Section 5 of Chapter 7. The requirement to make the annual financial report public in ESEF-format according to the ESEF RTS, has now been moved until the yearend 2021. As the change in the act was not effective on January 1st 2021, FIN-FSA published an announcement on December 21 2020 according to which it refrains from enforcement actions if the issuer does not publish the annual financial report for the financial year beginning on or after January 1st 2020 in ESEF-format. For more information see FIN-FSA’s news release.
It will be possible to compare and utilise financial statement data of different companies better when, in the future, financial statements are reported in a single electronic format (ESEF). Retrieving and analysing data will be facilitated. Reporting in an electronic, structured format will also enable new technology, such as artificial intelligence, to be used more effectively in analysing data.
What is ESEF and to whom does it apply?
European listed companies (issuers of shares and bonds operating in regulated markets) will have to report their entire annual financial reports in a single electronic format (ESEF) starting with financial statements for 2021. The annual financial reports will be prepared in XHTML format, and IFRS consolidated financial statement data included in the XHTML document will be marked up with XBRL tags. XBRL tagging will be done using iXBRL technology (InlineXBRL).
The ESEF XBRL requirement applies only to IFRS consolidated financial statements, and it does not apply to parent companies’ separate financial statements or management reports. The ESEF XHTML and XBRL requirements do not apply to financial statement releases or half-yearly reports. Reporting of companies listed in alternative marketplaces is also outside the new reporting requirements.
Behind the new reporting requirements are the amendments made in 2013 to the Transparency Directive concerning the harmonisation of listed companies’ transparency requirements. The amendments to the Directive included the requirement for listed companies to prepare annual financial reports in a single electronic format (ESEF). As a consequence of the amendments to the Directive, the European Securities and Markets Authority (ESMA) was tasked with developing a draft Regulatory Technical Standards (RTS), which further specify the electronic reporting format. On 29 May 2019, the European Commission published the RTS as a delegated regulation (ESEF RTS) on the ESEF approved in the EU and it is directly binding on listed companies. The regulation entered into force on 18 June 2019. A link to the delegated regulation in all official languages of the EU can be found here.
The technical implementation of ESEF is based on XHTML and iXBRL. According to ESEF plans, listed companies will have to prepare annual financial reports in XHTML format in stages starting with financial statements for 2021:
Financial statements for 2021:
- The XHTML-format document will include the primary financial statements, tagged with the XBRL language in accordance with a taxonomy: consolidated statement of profit and loss and comprehensive income, statement of financial position, statement of cash flows and statement of changes in equity.
- XBRL data will be embedded into the XHTML document using the Inline XBRL (iXBRL) mechanism.
- In financial statements for 2021, the notes to the consolidated financial statements, the management report and the parent company’s separate financial statement will be included in the XHTML document without XBRL tags.
Starting with financial statements for 2022:
- In addition to the primary financial statements, the notes to the financial statements must be tagged with XBRL tags. Notes will be marked up in accordance with ESEF minimum requirements as block tags, i.e. each note as a whole will be one XBRL tag, and individual line and column data within the note will not need to be tagged separately.
Structured electronic reporting with XBRL requires the use of a taxonomy. The taxonomy acts as a reporting account dictionary. ESMA’s ESEF taxonomy, which is based on the IFRS Foundation’s IFRS taxonomy, will be used in the reporting of financial statements. The ESEF taxonomy includes ESMA’s own extensions to the taxonomy, e.g. for the identification of companies.
In addition to the ESEF taxonomy, companies can use and create their own extensions to the taxonomy if they cannot find in the ESEF taxonomy an accounting meaning that describes the content of a line sufficiently well. Extensions, however, must be anchored to the closest accounting meaning of the ESEF taxonomy. In practice, the new accounting meaning is linked to the existing line of the taxonomy that is closest to this accounting meaning. The use of extensions reduces, however, the comparability of XBRL format data between different companies.
Detailed tagging with XBRL is applied to primary financial statements
The consolidated primary financial statements , i.e. consolidated statement of profit and loss and comprehensive income, statement of financial position, statement of cash flows and statement of changes in equity are marked up with XBRL tags specified by the taxonomy at the same level of detail with which the primary financial statements according to IFRS are prepared.
Notes as block tags
Notes to consolidated financial statements are covered by a reduced requirement, such that notes to the financial statements are marked up with XBRL as block tags, in which case one note as a whole is one XBRL tag, and there is no need to itemise the contents of a note with separate XBRL tags. More details might be added to the reported information later, after experiences gained in use. The ESEF taxonomy includes, however, the opportunity for more detailed XBRL tagging.
Currently, there is no legally binding EU regulation on the assurance of ESEF. A Q&A by the European Commission has been published (Questions and answers nr 7), but there are different interpretations about its legal validity in a situation where an obligation to audit would be established. The Commission’s Q&A anticipates the objectives of the Commission, and the Commission has earlier this year announced that it is working to develop its opinion on the assurance into juridically stronger form. The results of this work are expected earliest towards the end of the year, if Covid-19 exceptional situation has subsequently not changed the plans of the Commission. The assurance on ESEF will be arranged differently and with different time schedules in the legislation of EU countries.
Although the statutory audit would not cover the financial statements in ESEF-format, the issuers can arrange for the assurance on it, on a voluntary basis. FIN-FSA recommends that the issuers agree on a separate assurance engagement with their auditors and that the assurance is performed in accordance with the guidelines prepared by the Suomen Tilintarkastajat ry (Finnish Association of Authorised Public Accountants), link to the recommendation can be found here (only in Finnish).
Currently, listed companies submit their annual financial reports as a stock exchange release attachment file (pdf) to the national central storage facility for regulated information, either as a separate document or as part of an annual report. Following the entry into force of the Commission Regulation on ESEF, the consolidated financial statements in structured format and non-structured other information, such as e.g. the report of the board of directors and the parent company’s separate financial statements, will be included as zip-file in the XHTML document submitted to the central storage facility .
In Finland, the Helsinki Stock Exchange (Nasdaq Helsinki) acts as the maintainer of the central storage facility (Officially Appointed Mechanism, OAM) required by the Transparency Directive, to which listed companies submit regulated information.
Comparability of financial statement information requires detailed reporting using an XBRL taxonomy. Numerical data of financial statements can be compared or otherwise utilised across corporate and language boundaries when the numerical data has the same “name tag” in different companies and different countries, translated into each company’s own language. XBRL format information is easily transferable to different systems.
ESEF reporting permits the addition of a company’s own extensions to the taxonomy if the company cannot find in the ESEF taxonomy an XBRL tag corresponding in content to the accounting meaning of an item presented in the financial statements. A company’s possible own extensions to the taxonomy may, however, reduce the comparability of data between different companies.
It is recommended that companies assess what benefits they themselves can gain from also providing information in XBRL format to other purposes than only to regulatory reporting. Available information in XBRL format could be utilised, for example, in companies’ own sector peer analyses.
XBRL format reporting is used in many countries. The US Securities and Exchange Commission (SEC) already currently requires both US and foreign listed companies to report their financial statements in XBRL format. XBRL format information is also currently accepted by the trade register and tax authorities of a number of European countries, and XBRL is commonly used in the banking and insurance sector official reporting, including in Finland.
In Finland, the Tax Administration, the Finnish Patent and Registration Office and Statistics Finland are planning to accept financial information digitally in the future. Responsibility in Finland for maintaining the reporting code set and XBRL taxonomies for official reporting of financial information rests with the State Treasury. The State Treasury will activate companies with respect to digital official reporting of financial information.
ESMA has established a permanent working group to promote the implementation of ESEF. The purpose of the working group is to prepare the necessary additional guidance to listed companies and software suppliers for implementing the requirements of the ESEF regulatory standard. The aim is to apply the equalisation of the regulatory standard in the same way in different countries. Finland is participating in this ESMA work.
ESMA has published in its Final Report of May 25th 2021 a draft of an updated ESEF-RTS. The European Commission has three months to decide whether to endorse this technical standard. The Final Report is available here.
