XBRL in the Dutch Central Bank

Pro’s:• Political issues like reducing administrative burden

• Commitment towards European COREP and FINREP models

• To be prepared for the future

Con’s:• Existing e-Line functionalities versus XBRL capabilities

• Most Dutch banks show restraint when it comes to using XBRL

Resulting in: • Use international taxonomies when available and build national

• Support XBRL as additional import format

alternative structures like e-Line schema’s?

Some Considerations:• Business specifies reporting models in Excel

• Models are translated into XML Blueprints

• Taxonomies (COREP / FINREP) are a given

• Mapping data between systems not new for DNB

• A generic mapping solution

• ...
