Solvency capital requirement: LACDT = sum of explicitly and implicitly reported (IR.25.04, IR.25.06, Bank of England rule IR_bv2075)

A blocking check on the solvency capital requirement (IR.25.04) and solvency capital requirement - loss-absorbing capacity of deferred taxes (IR.25.06) templates, in the annual solo (ARS) return.

The rule in plain words

LACDT = sum of explicitly and implicitly reported

What to do if your return fails it

  1. 01Open the tables below and find the cells the rule reads.
  2. 02Add up the parts in your return and compare the result with the total.
  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.
  4. 04The Bank of England allows a small rounding difference, worked out from the decimals each value is reported with.
  5. 05It runs only when your filing indicators mark IR.25.06 as reported.
  6. 06This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
