The rule in plain words

The item "Eligible own funds to meet the SCR" reported in Impact of long term guarantees measures and transitionals (IR.22.01.01.01) should be equal to the sum of the "Tier I", "Tier II" and "Tier III"

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 table 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  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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.22.01 as reported.
  6. 06This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

A worked example

With simple numbers.

Illustrative values
Tier 11,200
Tier 2800

What the rule then expects

Eligible own funds to meet Solvency Capital Requirement must then be 2,450.

2,450Passes
2,550Fails

A file that reports 2,450 passes. One that reports 2,550 fails, by 100.

The numbers are illustrative, reported to the unit, so the rounding tolerance does not change the result.
