Group solvency: information on affiliates - total (GS Total): a total must equal the sum of its parts (C06.01.01.01, SC06.01.01.01, Bank of England check v4159_m)

A blocking check on the group solvency: information on affiliates - total (GS Total) (C06.01.01.01) and group solvency: information on affiliates of SDDTs - total (GS SDDT TOTAL) (SC06.01.01.01) templates, in the own funds (PRA001) and own funds for SDDTs (PRA116) returns.

Line4 Check runs it on the own funds (PRA001) and own funds for SDDTs (PRA116) returns, proven on test files, check by check: the same outcome on all six test files of those returns.

The rule in plain words

In row "Total" (0010) of Group solvency: information on affiliates - total (GS Total) (C06.01.01.01): "Qualifying own funds included in consolidated own funds" (column 0300) must equal the sum of "Qualifying tier 1 instruments included in consolidated tier 1 capital" (column 0310) and "Qualifying own funds instruments included in consolidated tier 2 capital" (column 0340).

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  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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. 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 C06.01.01 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
Qualifying tier 1 instruments included in consolidated tier 1 capital1,200
Qualifying own funds instruments included in consolidated tier 2 capital800
Together2,000
What the rule then expects

Qualifying own funds included in consolidated own funds must then be 2,000.

2,000Passes
2,100Fails

A file that reports 2,000 passes. One that reports 2,100 fails, by 100.

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

Which returns it applies to

Line4 Check runs it on the own funds (PRA001) and own funds for SDDTs (PRA116) returns on Bank of England banking taxonomy 4.1.1. The Bank of England applies it to own funds for SDDTs (PRA116) and own funds (PRA001) returns, as a blocking check.

The Bank’s own words and formula

The plain words above spell out the Bank’s formula, with each cell named from its templates. In the Bank of England’s list of validations, word for word:

v4159_m: [C06.01.01.01 (r0010)] {c0300} = {c0310} + {c0340}

The Bank of England's formula. Cells are written as {t: table, r: row, c: column}.

{t: C06.01.01.01, r: 0010, c: 0300} = {t: C06.01.01.01, r: 0010, c: 0310} + {t: C06.01.01.01, r: 0010, c: 0340}

Checks like this one, run at the point of submission, are the first step to real-time supervision. Line4 builds SupTech software for financial regulators that runs checks like these as each return arrives.
