ESEF: Understanding What’s at Stake

Below are four key takeaways from a recent article by Bartek Czajka. His complete thoughts are available on the Toppan Merrill blog.

Who is Affected By the Mandate?

The mandate applies to all issuers within the EU. All financial statements for annual periods beginning on or after January 1, 2020 are affected. There is no phase-in by company size or sector.

What Brought the Mandate About?

The mandate began with the European parliament's goal to create a ''single digital market” that is machine-readable and more easily discoverable, bringing EU capital markets into the digital information age. In turn, this goal led to the 2013 EU Transparency Directive changes. ESMA then had the task of defining a single digital financial reporting format. The European single electronic format is the result.

When Do the ESEF Requirements Take Effect?

Annual financial reports (AFRs) in xHTML format and iXBRL-tagged IFRS consolidated statements are due four months after year-end. We'll begin seeing the first ESEF filings in early 2021.

What Is Your Advice for Issuers?

Engage an expert. iXBRL bridges the gap between humans and machines. So, XBRL expertise requires understanding both languages. But experts must also know how to apply the right tags and how to format reports correctly. All this ensures critical financial data is both compliant and accurate.
