Session Outline

  • The core Taxonomies - IFRS and US-GAAP

  • Extension Taxonomies

    • Local GAAP

    • Local regulation

    • Entity specific extensions


What is a taxonomy l.jpg
What is a Taxonomy?

An XBRL taxonomy is a description and classification system for the contents of financial statements and other business reporting documents. XBRL taxonomies can be regarded as extensions of XML Schema, augmented with written documentation and a number of additional XML Linking (XLink) files. Taxonomies represent up to hundreds of individual business reporting concepts, mathematical and definitional relationships among them, along with text labels in multiple languages, references to authoritative literature, and information about how to display each concept to a user.

The core taxonomies ifrs and us gaap l.jpg
The Core Taxonomies - IFRS and US-GAAP

  • There are two dominant GAAPs

    • IFRS

    • US-GAAP

    • They are converging, but not equivalent

  • The Taxonomies that capture IFRS and US-GAAP present powerful representations of financial reporting data.


The demand for extensions l.jpg
The Demand for Extensions

  • Intra-Jurisdictional

    • Industries

    • Regulatory Filings

  • Extra-Jurisdictional

    • Cross jurisdictional comparisons

      • Can I compare elements? Which ones?

    • Convergence to IFRS around the world

      • Concepts are very common across jurisdictions

      • Aligning these structures makes sense


What is the extension process l.jpg
What is the Extension Process?

  • FRTA defines it as adding and removing concepts and relations.

  • Result is a “Taxonomy” that meets a particular need.

Local gaap l.jpg
Local GAAP specific process.

  • IFRS is not yet used by many major jurisdictions – there is still a demand for local GAAP

  • Even after IFRS there will be local needs

    • eg. New Zealand

      • Sector neutrality

      • Local requirements

  • Unspecified elements

    • Assets or expenses

  • The demand for entity specific extensions depends on how comprehensive the core taxonomies are.


Regulatory extensions l.jpg
Regulatory Extensions specific process.

  • Statistics

  • Company Returns

  • Stock Exchange

  • Tax

  • Monitoring Agencies

  • There will be many elements common to several regulatory agencies. Hence, one regulatory “extension” in a jurisdiction is achievable.

    • And regulatory extensions will have common elements across jurisdictions.

    • The message is that there is the potential to develop accepted international taxonomies in many domains.


Entity specific extensions l.jpg
Entity Specific Extensions specific process.

  • How will all this work?

    • Taxonomy creation

    • Taxonomy loading and instance creation

  • The extension process can be used to build XBRL power into your internal needs

    • Management reporting

    • Integration with non-financial reports


Summary l.jpg
Summary specific process.

  • A Taxonomy based on a general purpose document will not meet the needs of all users for all uses.

  • XBRL provides a process for building extensions to core Taxonomies.

  • Extension taxonomies will be created by intermediaries (such as ICANZ) and the technology will soon make it easier for entities to create their own taxonomies.

  • We are not yet there but demand is increasing and the ability to supply is increasing.

  • We may not be far off a critical cost-benefit cross-over point.
