A blocking check on the balance sheet template (IR.02.01), in the annual third-country branch (ARB) return.

The rule in plain words

Technical provisions - life = best estimate

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.02.01 as reported.
  4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
