12. 12 Many EU countries where Dexia is active are using XBRL as reporting language but Not in all countries Mostly presented and implemented as an additional burden In Belgium an additional XBRL reporting is required for the Balance Sheet Office reporting (statutory accounts of approx 270.000 companies), National Bank of Belgium.

13. 13 Use XBRL as a tool for more harmonization, flexibility and gain of time both vertically and horizontally We thus need: XBRL at the beginning of the reporting processes (public, COREP, FINREP and internal) Softwares that read XBRL One integrated database (kind of Group taxonomy) « One fits all »

14. 14 Used by credit departments Used instead of xls on websites (like Microsoft, Monte dei Paschi di Siena, etc.) Other regulatory reporting (like VAT and tax in NL, AML in Spain, etc.) Internal reporting (reconciliation Consolidation and Risk databases) Mapping with new regulatory requirements Necessity to create a working group within the group with technical specialists and business specialists Better coordination Decrease of cost

15. 15 A potential integration tool for the group reporting External : Known and understood by all May be the base of a worldwide reporting May avoid repetitive reporting in different presentations, but with the same content to regulators and local authorities Internal : May be the base for internal reporting (consolidation) May allow drill-down analysis with a good organisation of taxonomy Will make the life easier for Financial Communication and members of the Boards when they compare the contribution of one company in the consolidated accounts with the financial statements published by a subsidiary in its country

16. 16 A potential integration tool for groups Only one reporting, for internal and external reporting Possibilities for people to move from one company to another Advantage for managers to understand how transactions are recorded and the impact on the financial statements Powerful tool for the controller and people from investor relations to analyse the contents of the financial statements, both in the group and sub – groups, including the local regulatory reporting Use of IFRS and worldwide taxonomy may help groups to more easily integrate newly acquired subsidiaries

17. 17 Regulatory interpretations Example Collateral definition Equity split Counterparties Calculations Etc. Software offer COREP + FINREP IFRS Internal Motivation of people (difficulty to see the benefits)

18. 18 Stronger CEBS policy, but also more communication to banks with regards to the XBRL benefits (XBRL should not be a cost and administrative burden) Stronger banking industry involvement Software providers needs to understand the banks real needs One single definition of taxonomy

19. 19 Press release of April 2007: cooperation between US and EU, including regulatory matters BUT: SEC-FDIC EU CEBS This way ? Or this way ? Bundes bank SGCBBdICBFAetc.FSA

20. 20 Within ONE group ONE tag ONE definition ONE validation/business rule ONE taxonomy ONE country ONE EU reporting ONE CEBS (FINREP-COREP) EU base reporting completed by additional country requirements => Need to follow the XBRL principles
