Two many extensions, too many inconsistent anchors in ESEF reports!
The quality of the xbrl data, beyond the technical validations that are automatically performed by the tools, is dependant on the implication, the understanding of the challenges and the reviews of the issuers.
It is also dependant on the structure of the base ESEF taxonomy. This document can be considered as a starting point of what could be a “significant improvement” for reaching a well-structured hierarchical reporting taxonomy that would ease the search for a tag matching a line item, the search for a specific entity disclosure wider anchor, the reduction of entity extensions.
The quality of the digitized data is paramount.
The fact that ESEF reports are in XBRL is a guarantee that all technical aspects are met:
all reports are validated (with a few exceptions) by XBRL and the Compliance Suite tests.
Is this sufficient to ensure that all data quality criteria are met? Looking at the 2022 reports, there is still a lot of room for improvement.
This document summarizes the changes introduced in the 2023 ESEF reporting manual. These updates may have an impact on issuers preparing their 2023 annual report in ESEF.
This document describes changes:
- in the 2022 ESEF taxonomy from the 2021 taxonomy for issuers who used the 2021 taxonomy for their 2022 financial statements and
- in the 2023 IFRS taxonomy from the 2022 taxonomy to anticipate the changes in their 2023 ESEF.
