Own funds: values must agree (IR.23.01, Bank of England rule IR_bv0672)

A blocking check on the own funds template (IR.23.01), in the quarterly solo (QRS) and annual solo (ARS) returns.

The rule in plain words

The "Tier 1 - restricted" value of "Available and eligible own funds/Total eligible own funds to meet the SCR" reported into the template Own funds (IR.23.01.01.01) should be the minimum between 25% of "Total eligible own funds to meet the SCR/Tier 1 - unrestricted" and "Total eligible own funds to meet the SCR/Tier 1 - restricted" when "Tier 1 - unrestricted" value of "Available and eligible own funds/Total eligible own funds to meet the SCR" is greater then 0

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.

This is a blocking check. A return that fails it is normally rejected, so fix it before you submit. It runs only when your filing indicators mark IR.23.01 as reported.

{t: IR.23.01.01.01, r: R0540, c: C0030, z: Z0001} = min(max({t: IR.23.01.01.01, r: R0540, c: C0020, z: Z0001}, 0) * 0.25, {t: IR.23.01.01.01, r: R0500, c: C0030, z: Z0001})
