5. Business case - Definition
COREP:
defining a COmmon REPorting framework around the solvency ratio for credit institutions and investment firms under the European Union Capital Requirements.
(Based on Basel II, Pillar I)
Committee of European Banking Supervisors

6. Business case - requirements
Flexibility: each supervisor is allowed to choose the scope as well as the level of aggregation of information required; the framework will allow for flexibility also to accommodate for differences in the exercise of the national options foreseen in the Capital Requirements, for instance with reference to the treatment of small institutions;
Consistency: the same concepts and terminology have been used as far as possible;
Standardisation: the number of different templates has been minimised.

17. COREP project: Request for testing
Common framework for the reporting of the solvency ratio (COREP) by credit institutions
To test the COREP XBRL project, institutions are invited to participate by providing test data on a best effort basis. Please visit details. 
Who can participate? Any institution that has access to data of banking activities, like for example, credit institutions, consultant firms or any other party interested in participating.
How to participate? Institutions should provide test cases using this spreadsheet ( and attaching all the relevant documentation associated. No XBRL knowledge is necessary!
Collaborating institutions will acquire through their participation in this process:
A deeper and better understanding on the COREP reporting framework for the solvency ratio.
A chance to provide comments on how the proposed framework works. This may help institutions to provide comments on the CEBS consultation paper.
An early knowledge about the availability in their systems of the information that will be required in the future for solvency reporting.
The collaboration in this open process will also allow the Institutions to benefit from the experiences, comments, suggestions and questions posed by other members of the banking industry, market participants and XBRL experts.
