Validation rules
The NBB publishes the checks it runs on this return. They could not be counted from the published material. They are written for people to read; software cannot run them as published. Source
How they are written: Word and Excel lists of validation tests, and a PDF of tests between the Solvency II reporting and the annual accounts.
How they were counted
Not counted: the CPA page links the validation tests for annual accounts, solvency margin and covering values and the life and non-life statistics as .doc and .xls files that robots.txt does not allow to be read; the Solvency II versus annual accounts tests (validatietests.pdf) were not counted.
Counts are in the NBB's own unit, so they are not comparable with other regulators' counts.
Public data
No published data from this return was found. No data from this return published by the NBB was found on the pages checked. Source
