Non-life claim development: two values must match (IR.19.01, Bank of England rule IR_bv1367)

A blocking check on the non-life claim development template (IR.19.01), in the annual solo (ARS) return.

Check your file for this ruleWhat to do if it fails

The rule in plain words

In IR.19.02: The cumulative claims paid to the reporting as at date related to origin year N reported in {R0250, C0180} must equal that sum of the incremental claims paid for that origin year reported in the claims paid triangle at {R0250, C0010 to 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 tables 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.19.02 as reported.
  4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

The cells it reads

Non-life claim development: gross claims paid (non-cumulative) - development year (absolute amount) (IR.19.01.01.01)

Row

  • R0250N

Column

  • C00100

Non-life claim development: gross claims paid (non-cumulative) - current year, sum of years (cumulative) (IR.19.01.01.02)

Row

  • R0250N

Column

  • C0180Sum of years (cumulative)

A worked example

With simple numbers.

Illustrative values
N, 01,200
What the rule then expects

N, Sum of years (cumulative) must then be 1,200.

1,200Passes
1,300Fails

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

The numbers are illustrative.
