"Total tier 1 capital" must equal the sum of "Additional tier 1 capital" and "Common equity tier 1 capital" (C06.02.01.01, SC06.02.01.01, Bank of England check v0147_h)

A blocking check on the group solvency: information on affiliates (GS) (C06.02.01.01) and group solvency: information on affiliates of SDDTs (GS SDDT) (SC06.02.01.01) 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 Group solvency: information on affiliates (GS) (C06.02.01.01): "Total tier 1 capital" (column 0150) must equal the sum of "Additional tier 1 capital" (column 0210) and "Common equity tier 1 capital" (column 0180).

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  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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 C06.02.01 as reported.
  6. 06This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
