The IRIS CARBON® Approach
IRIS CARBON® handled Hellenic Bankʼs ESEF reporting by aligning with the above-identified objectives.
1. Setting Up Hellenic Bankʼs 2020 Document
IRIS CARBON® started by setting up the Hellenic Bankʼs 2020 base document by using their already published 2020 annual report. This required loading the 2020 annual report onto the IRIS CARBON® platform. Appropriate tags were then selected from the ESEF taxonomy and applied to the base document.
XBRL experts at IRIS CARBON® came across situations where there was no specific element in the ESEF taxonomy matching the line items mentioned in the annual report. At that point, they created custom elements (also known as extensions) to map the unique or company-specific disclosures. Anchoring relationships were then used to further define these extensions.
Team IRIS CARBON® then validated the files to verify they were error-free.
2. Training Sessions On Reviewing The iXBRL Tagging
Once the base document was ready, IRIS CARBON® planned training sessions around the ESEF mandate and review module of the platform. IRIS CARBON® walked team Hellenic Bank through the ESEF taxonomy. Several important concepts on ʻhow to review the iXBRL documentsʼ and ʻvalidating the files using an integrated XII certified Bushchat validatorʼ were discussed. With this information in hand, team Hellenic Bank was able to conduct a thorough assessment of tags in the newly generated 2020 iXBRL annual report.
The workshops were held using a variety of extensive educational videos on using the IRIS CARBON® platform review module and the dashboard. Video recordings were maintained for future reference.
3. Creation And Publication Of The 2021 iXBRL Annual Report
As a result of Hellenic Bankʼs review and approval of the iXBRL 2020 annual report, IRIS CARBON® had the base ready for the iXBRL 2020 annual report. Now when it came to the ESEF 2021 filing, a similar procedure was followed. Hellenic Bank provided the data for the fiscal year 2021, this was further loaded on the IRIS CARBON® platform. Using IRIS CARBON®ʼs rollover function, the previously approved tags by team Hellenic Bank were used to reapply on the iXBRL 2021 annual report. Where necessary additional tags, extensions, and anchoring relations were created and added to the 2021 XBRL document.
Once the iXBRL 2021 annual report was processed Hellenic Bank was asked to review the report and then approve the same. When it came to reviewing the ESEF annual report, it was observed that the Hellenic Bank team had become well-acquainted with the review module of the IRIS CARBON® platform because of the educational videos. The stage was now set for a successful 2021 iXBRL annual reportʼs live filing.
