Society of Lloyd's own funds and capital requirements: two values must match (IR.23.05, Bank of England rule IR_bv0129)

A warning on the society of Lloyd's own funds and capital requirements template (IR.23.05), in the annual solo (ARS) return.

Check your file for this ruleWhat to do if it fails

The rule in plain words

Own funds attributable to the Society available to meet Lloyd's SCR' reported in {IR.23.05.03, R0130, C0010}' should typically be the same as 'Own Funds attributable to the Society available to cover Central Requirement' reported in {IR.23.05.03, R0170, C0010}

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.23.05 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.

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