The IFRS Formula Linkbase 2012 is now available to download. The current version of the formula linkbase is an updated version of the formula prototype which was released in October 2011. The 2012 formulae are designed to work with the IFRS Taxonomy 2012. The majority of the improvements between the current version and the prototype are related to the content.
The formula linkbase can be used with software packages supporting the XBRL formula specification 1.0 and allows for additional validations of the reported facts. The IFRS Formula Linkbase 2012 is developed in a generic manner, which means it can be used directly on the filings created, on the basis of the IFRS Taxonomy (instance documents) or the company specific extensions to the IFRS Taxonomy (filer extension taxonomy and instance document). The guidance documentation for formula linkbase is available to download with the current release.
Technical changes between the current version and the prototype include:
· Positive and negative formula validation has been placed in separate files.
· Redundant members in the filter for the Dimension aggregation formulae are now removed.
· Precondition expressions in the validation have been simplified (Earnings per share formulae).
Some software packages can be used to execute this formula linkbase:
- Fujitsu formula editor
- Reporting Standard XBRL Processor
The guidance documentation for Formula linkbase is available in the resource materials section of the IFRS website.
