Presentation Transcript

  1. IFRS Taxonomy Architecture Holger Obst, Maciej Piechocki XBRL project managers

  2. Agenda • Introduction • Requirements • Development • Architecture • Visualisation • Summary

  3. Requirements • Completeness and consistency with IFRS • Documentation/visualisation • Extensibility • Stable platform • XBRL Specification compliance

  4. Development

  5. Development

  6. Architecture • General considerations • Taxonomy schemas • Taxonomy linkbases • New XBRL technologies

  7. IFRS Taxonomy Framework

  8. Release Timeline • IFRS taxonomy reflects standards and interpretations effective as at the taxonomy release date • IFRS taxonomy architecture is aligned with the IASB timeline for releasing of the standards • Modelling of standards and interpretations as published by the IASB within one yearly IFRS taxonomy release • Consideration of early adoption standards and their inclusion in the reporting process

  9. Taxonomy Schemas • Single schema approach • Additional roles schema

  10. Taxonomy Linkbases • English label linkbase referenced from core schema • Other than English label linkbases modularised according to languages • Presentation, calculation, definition, reference modularised according to standards and interpretations • Presentation, calculation and definition linkbases placed in single files for each statement or disclosure

  11. Reference Linkbase

  12. Reference Linkbase

  13. Presentation Linkbase • No changes in the expression of hierarchies in the presentation linkbase comparing to previous IFRS-GP taxonomy releases • Enhancement to the way of expressing two dimensional tables • Use of a double extended links in the presentation linkbase (for horizontal and vertical alignment) with additional attributes in order to express and render changes tables • Alternative use of dimensions for changes tables

  14. Definition Linkbase • Main uses of dimensions: • segment reporting (IAS 14 and IFRS 8); • reconciliation (restatements); • first time adoption; • fair presentation override; • … • Only explicit dimensions (defined or open) • Hypercubes are open and where possible default dimension specified

  15. New XBRL Technologies • Versioning • Versioning solution as additional information for the IFRS 2008 taxonomy • Rendering • Tabular rendering in presentation linkbase • Instance rendering out of scope • Formulas • No implementation for IFRS 2008 taxonomy • Prototypes in 2008 for cross-context calculations and dimensional calculations

  16. Visualisation • Beside providing a stable platform the new taxonomy design allows better visualisation • XBRL Educational Bound Volume for IFRS • Interactive between XBRL information and International Financial Reporting Standards • Integrated approach of taxonomy viewer and eIFRS • Human readable XBRL information of taxonomy structure

  17. Summary • Timeline alignment with the IASB • Use of dimensions • Modelling of tables • IFRS Taxonomy Architecture – discussion paper • IFRS Taxonomy Prototype
