Own funds: two values must match (IR.23.01, Bank of England rule IR_bv0545)

A warning on the own funds template (IR.23.01), in the quarterly solo (QRS) and annual solo (ARS) returns.

The rule in plain words

The item "Total basic own funds after deductions Tier 1 unrestricted" reported in Own funds (IR.23.01.01.01) should be equal to " Total eligible own funds to meet the SCR Tier 1 unrestricted"

The headline gives only the template and the kind of check, because the rule is too long to say in a headline. The plain words above say all of it.

What to do if your return fails it

  1. 01Open the table below and find the cells the rule reads.
  2. 02The two values must be the same. Find which of the two is right, and correct the other one.
  3. 03It runs only when your filing indicators mark IR.23.01 as reported.
  4. 04This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.

The cells it reads

Own funds (IR.23.01.01.01)

Rows

  • R0290Total basic own funds
  • R0540Total eligible own funds to meet the SCR

Column

1,300Fails

A file that reports 1,200 passes. One that reports 1,300 fails, by 100.

The numbers are illustrative.
