1. Proof-of-concept sample Eurofiling data modelling and taxonomy architecture 2011-06-12

2. Proof-of-concept materials original templates: – set of 11 templates (original and normalized, including rendering coordinates according to the Data Points Model) – scope: FINREP/BSI-MIR use cases – including IFRS 9 (anticipation of change) data points model: – base items and breakdowns – common (COM) and domain specific items (DSI) – taxonomy generation data (XBRL Tax Generator input format) XBRL Taxonomy Generator load file (for tables 3, 5 and 7) Taxonomy: – main components: primary items, dimensions, domains and general subdomains for COM and DSI cross template hypercubes – templates: table linkbase (syntax according to the Eurofiling approach) formula linkbase (template specific and cross template) 2

3. Original Templates Scope Table 1 - Statement of financial position Table 2 - Income statement *Table 3 - Impairment of debt instruments Table 4 - Derivatives *Table 5 - Assets by counterparty residence and currency Table 6 - Details on certain loans *Table 7 - Tangible and intangible assets subject to operating lease Table 8 - Statement of changes in equity Table 9 - Statement of comprehensive income Table 10 - Related party disclosures Table 11 - Scope of the group *data model covers all tables, cross template hypercubes, rendering and formulas defined for Tables 3, 5 and 7 3

4. Original Templates Normalized, including rendering coordinates and business rules 4

5. Data Points Model Content lists of items – 16 base items – 16 domains (171 members of which 25 marked as common) – 23 explicit dimensions (of which 8 marked as common) – 2 typed dimensions, one typed domain (marked as common) hierarchies of domains – ELRs – default members for dimensions – subdomain specific labels taxonomy generation data – folders structure, file names, namespaces – data types 5
