Solvency capital requirement - non-life and health catastrophe risk: a total must equal the sum of its parts (S.27.01, EIOPA rule BV277_1)

A blocking check on the solvency capital requirement - non-life and health catastrophe risk template (S.27.01), in the annual solo (ARS), annual group (ARG) 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 item "Total Flood EEA Regions before diversifications" reported in Solvency Capital Requirement - Non-life and Health catastrophe risk (S.27.01) must be equal to the sum of the regions reported above

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.

EIOPA writes it out as separate checks, one for each table or return it covers. Line4 Check runs two of them (BV277_1-1 and BV277_1-2), and a failure names the one that failed.

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  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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 S.27.01 as reported.
  6. 06This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

EIOPA's formula, for BV277_1-1. Cells are written as {t: table, r: row, c: column}.

{t: S.27.01.01.04, r: R1400, z: Z0001} = sum({t: S.27.01.01.04, r: R1260; R1270; R1280; R1290; R1291; R1292; R1295; R1300; R1310; R1320; R1321; R1325; R1330; R1335; R1340; R1350; R1360; R1370; R1380; R1385; R1390, z: Z0001})

BV277_1-2:

{t: S.27.01.04.04, r: R1400, z: Z0001} = sum({t: S.27.01.04.04, r: R1260; R1270; R1280; R1290; R1291; R1292; R1295; R1300; R1310; R1320; R1321; R1325; R1330; R1335; R1340; R1350; R1360; R1370; R1380; R1385; R1390, z: Z0001})
