Solvency capital requirement - for undertakings on standard formula: a total must equal the sum of its parts (SR.25.01, EIOPA rule BV1052)

A warning on the solvency capital requirement - for undertakings on standard formula template (SR.25.01), in the annual solo (ARS) and annual branch (ARB) returns.

It applies to 2.8.2 returns too, the release for the 2026 returns, and Line4 Check runs it there as well.

The rule in plain words

The Amount/estimate of Loss-absorbing capacity of deferred taxes should be equal to the sum of items "Amount/estimate of LAC DT justified by reversion of deferred tax liabilities", "Amount/estimate of LAC DT justified by reference to probable future taxable profit", "Amount/estimate of AC DT justified by carry back, current year", "Amount/estimate of LAC DT justified by carry back, future years"

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. 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  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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. 04EIOPA allows a small rounding difference, worked out from the decimals each value is reported with.
  5. 05It runs only when your filing indicators mark SR.25.01 as reported.
  6. 06This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.
