4. IRIS BUSINESS SERVICES (INDIA) PVT LTD XBRL Solutions4 In This Session XBRL Taxonomies – A quick look at the concepts The Taxonomy building process XBRL Taxonomies with the RBI Harmonization with the Indian GAAP taxonomy Way Forward

5. IRIS BUSINESS SERVICES (INDIA) PVT LTD XBRL Solutions 5 TAXONOMIES

6. IRIS BUSINESS SERVICES (INDIA) PVT LTD XBRL Solutions6 XBRL Taxonomies A system understandable description and classification of business and financial terms It is commonly referred to as dictionary of business and financial terms Contains the universe of accounting and other related concepts Contains the XBRL properties of the elements

7. IRIS BUSINESS SERVICES (INDIA) PVT LTD XBRL Solutions7 Role of taxonomies Standardization Facilitates Understanding of the Data System Enables Reuse, Data Exchange and Comparisons

8. IRIS BUSINESS SERVICES (INDIA) PVT LTD XBRL Solutions8 XBRL – A Quick Recap XBRL is an XML based standard

9. IRIS BUSINESS SERVICES (INDIA) PVT LTD XBRL Solutions9 And XML … XML is a key Internet standard for transmission and interoperability  Electronic transmission is newer than electronic storage  With the growth of the Internet, transmission of data is exploding  No Interoperability problems earlier – lots of interoperability problems now  XML uses "tags" to define data and is self-descriptive  XML has been developed by w3 consortium

10. IRIS BUSINESS SERVICES (INDIA) PVT LTD XBRL Solutions10 Extending XML - XBRL XBRL combines hierarchical xml data with relationships and references between the data points. XBRL combines hierarchical xml data with relationships and references between the data points. It uses Xlink technology of linking xml files It uses Xlink technology of linking xml files It links the data xml files with various other files containing definitions, presentation, calculation, references relationships It links the data xml files with various other files containing definitions, presentation, calculation, references relationships XBRL data files are a set of xml and xsd files. XBRL data files are a set of xml and xsd files.

11. IRIS BUSINESS SERVICES (INDIA) PVT LTD XBRL Solutions11 Key Taxonomy Concepts Taxonomy Built from Schema and linkbases Schema – Contains the element declarations – XBRL properties (Data type, Balance type etc.) Linkbases – Interrelationships between elements – References to regulatory material – Human readable definitions of elements – Five types of linkbases

13. IRIS BUSINESS SERVICES (INDIA) PVT LTD XBRL Solutions13 XBRL Taxonomy & Instance Architecture Contd. Let’s take following data as sample: Bajaj Auto Limited, March 31 2009 Report Statement of Income (In Rs.

15. IRIS BUSINESS SERVICES (INDIA) PVT LTD XBRL Solutions 15 DIMENSIONS

16. IRIS BUSINESS SERVICES (INDIA) PVT LTD XBRL Solutions16 Dimensions in XBRL The XBRL 2.1 base specification enables storing defined set of dimensions for a data element: 20000 Company Name: ABC XBRL Tag Name: RevenueNet Period: 2008-04-01 to 2009-03-31 Label: Net Revenue आय Curreny: INR All of these dimensions together uniquely identify the data point 20000

17. IRIS BUSINESS SERVICES (INDIA) PVT LTD XBRL Solutions17 Dimensions in XBRL The dimensions specifications released in 2008 enable storing additional dimensions. In the previous example: Revenue has two dimensions, By Product & By Region. Other Examples: – Investments by Type, by Periodicity. – Advances in India, outside India – Credit Risk On Balance Sheet, Off Balance Sheet

18. IRIS BUSINESS SERVICES (INDIA) PVT LTD XBRL Solutions18 Terminology in Dimensions Primary Item Hypercube Dimension Domain and Domain Member Explicit and Implicit Dimensions Aggregator-Contributor All / Not All composers

19. IRIS BUSINESS SERVICES (INDIA) PVT LTD XBRL Solutions19 Few XBRL Taxonomies around the world.. US-GAAP 2009 – Financial Reporting to US SEC IFRS 2009 – Represents IFRS 2009 FinRep & Corep – Financial Reporting & BASEL II based Reporting in CEBS* XBRL GL Indian Taxonomies Indian GAAP – Based on IFRS 2006 Architecture – Caters to Indian Accounting Standards – Taxonomy owned by ICAI RBI – BASEL II – Based on Corep, though have a different architecture – Used by banks to file their RCA (Returns on Capital Adequacy) – Taxonomy owned by RBI

20. IRIS BUSINESS SERVICES (INDIA) PVT LTD XBRL Solutions20 Taxonomies designed for RBI..  RCA 2 Taxonomy for BASEL II Returns  Form A taxonomy for Section 42 returns  Taxonomy for GPB returns  Taxonomy for Financial Reporting * Based on the underlying principle – common elements to be defined only once

29. IRIS BUSINESS SERVICES (INDIA) PVT LTD XBRL Solutions29 ICAI : Bank Taxonomy Element identification Analysis of regulatory literature. – Banking regulation Act – Annual Reports of 25 banks (documenting common practice) – SEBI Listing agreement – Accounting standards* – Companies Act* *These have been referred while defining C&I taxonomy. Identifying the common elements, already defined in C&I taxonomy # # Additional task required for designing subsequent taxonomies

30. IRIS BUSINESS SERVICES (INDIA) PVT LTD XBRL Solutions 30 ICAI : Bank Taxonomy Taxonomy Structure Based on IFRS 2006 structure –Banking specific tags have been defined additionally in the core schema –Separate extended links for the bank reporting appended to existing taxonomy –Basic structure of financial statements and their details, both included in the same extended link (unlike C&I) –No dimensions have been defined, instead extended links have been used Primary references – BR Act and RBI circulars

IFRS 2008 IFRS 2006IFRS 2008 Release date15 th August 200624 th June 2008 ModularityThe files (Schema and linkbases) are located in one folder. The files are organized based on the IAS and IFRS. There is a core schema containing all the elements defined, and linkages to the different folders for every IAS and IFRS. StructureThere was a common entry point, wherein the users had to select and browse the taxonomy. The entry point is entity specific and hence has to be created by the user of the taxonomy. Elementsi) 4100 (approx)i) 2700 (approx) ii) Elements outside the IAS and IFRS (common practices and industry specific) are included in the taxonomy ii) Elements only from the IAS and IFRS are part of taxonomy Dimension Vs.
