1. 17th XBRL International Conference
“Bank of Spain – XBRL Formulae for COREP and FINREP”
Víctor Morilla (Banco de España)
Eindhoven May 5-8, 2008

2. The new Formulae specification
Defining transformation rules to produce new facts from existing ones
Verifying data reported according to validation rules
Value assertions
Existence assertions
Consistency assertions
Documenting those rules
Features:
Business oriented
Maintainable
Extensible

3. Validation example
Own funds > Credit Risk Cap.Req + Market Risk Cap.Req
$of > $crcr + $mrcr
Concept filter = corep:MarketRiskCapitalRequirements
Concept filter = corep:CreditRiskCapitalRequirements
Concept filter = corep:OwnFunds

4. Dimensional validation example
$total <= sum($byCountry)
Dimension filter : Country = Total
Dimension filter : Country = child(Total)
Dimension Country
Total
France
Spain …
Concept filter = Incomes
Expenses
Profit
Profit before taxes

5. Advantages Powerful but simple model to express business rules
Higher quality of data
Shorter time to elaborate and debug information
Cost reduction for both the authority and the regulated entity

6. But…
The development of common formulae linkbases exposes some lack of homogenization among supervisors
Precision of the required data

7. Thanks for your attention
