Quarterly solvency return for a single insurer (QRS)

A regulatory return listed by the Bank of England (PRA), insurers, United Kingdom.

A quarterly snapshot of one insurer: its Solvency UK balance sheet, life and non-life income and expenses, a list of every investment and open derivative, its technical provisions (the value of what it owes policyholders) and its own funds (the capital it holds). Together with the other returns it gives the PRA what it needs to assess the firm's business, risks, valuation and capital (Reporting 2.2). Source

Line4 Check for Solvency UK runs the Bank of England's own validation rules on a QRS file in your browser, free. Your file never leaves your computer. What it runs, from its published manifest:

  • Bank of England Insurance Taxonomy 2.2.0: all 267 of the Bank's XBRL validation rules for this return.
  • Also the 49 filing checks from the Bank's XBRL Filing Manual v1.0.1.

It is not a substitute for the validation the supervisor runs when you submit.

Validation rules

267 rules, as counted from the PRA's published material. Software can run them exactly as published. Source

How they are written: XBRL Formula 1.0 assertions in the taxonomy package (val folder of each framework), plus an Excel list of every rule with its expression, severity and entry points.

The rules, on bankofengland.co.uk

How they were counted

Distinct rule codes in sheet 'ir' of 'Bank of England Insurance Taxonomy Validations v2.2.0 - IR.xlsx' (validations zip) whose 'Severity and modules' column names QRS, with 'Include in XBRL' = yes and 'Deactivated' = no (268), less 1 rule code set to 'Deactivate' on sheet 'Version 2.2.0' of the validation deny list. The sheet lists 277 rule codes for QRS in all; 9 have 'Include in XBRL' = no.

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