Quarterly balance sheet of Irish branches of EEA insurers (SNST.1)

A regulatory return listed by the Central Bank of Ireland (CBI), Ireland.

A short quarterly balance sheet from Irish-resident branches of insurers headquartered in another EEA country. Irish insurance statistics follow a 'host' approach that includes these branches, while Solvency II data follows a 'home' approach, so this template fills the gap. Source

Validation rules

7 rules, as counted from the CBI's published material. They are written for people to read; software cannot run them as published. Source

How they are written: PDF list; the template's own validation tabs apply the same rules.

The rules, on centralbank.ie

How they were counted

Numbered arithmetic rules in section 4.1 ('List of validation rules') of 'SNST.1 validations'. In-house period-on-period and threshold checks are applied afterwards and are not listed.

Counts are in the CBI's own unit, so they are not comparable with other regulators' counts.

Public data

Published only added up across firms. Used to add Irish branch activity (the 'host' approach) to the Central Bank's insurance corporations statistics. Source
