6. Application of the Supervisory Review Process CEBS CP03 | May 2004 Edit document title in the view master slide CEBS document code | 00 Month 2004 6 CEBS’ stance towards XBRL Cover note to the Framework for Common Reporting of the New Solvency Ratio “While national supervisory authorities are free to decide on the technical transmission specifications to implement the reporting framework, CEBS considers that XBRL can be a helpful tool in constructing a harmonised European reporting mechanism. CEBS will therefore develop an XBRL platform and make it available free of charge to national authorities and supervised institutions. XBRL taxonomies will be developed for both the COREP and FINREP (Financial Reporting) frameworks.”

Avoiding having multiple systems for each country Small banks may benefit from a free standard like XBRL and the economies of scale derived from the development of the XBRL taxonomy by CEBS. Possibility of using same system to other reporting (e.g. tax returns) Supervisors may benefit from economies of scale. XBRL provides the flexibility to accommodate in a consistent manner different reporting and legislation.

Application of the Supervisory Review Process CEBS CP03 | May 2004 Edit document title in the view master slide CEBS document code | 00 Month 2004 9 Plusses of XBRL for supervision XBRL provides the IT framework for the reuse of harmonised terms and definitions. Regardless of the lay-out of the national templates Regardless of the language used in the national implementations. With higher levels of reliability, since the taxonomies incorporate the validation rules needed. References included in the taxonomies determine the content of the items. The more widespread is the use of XBRL, the more benefits from XBRL can be obtained.
