Group solvency: information on affiliates of SDDTs (GS SDDT): a total must equal the sum of its parts (SC06.02.01.01, Bank of England check boe_b0080_ss)

A blocking check on the group solvency: information on affiliates of SDDTs (GS SDDT) template (SC06.02.01.01), in the own funds for SDDTs (PRA116) return.

Line4 Check runs it on the own funds for SDDTs (PRA116) return, proven on test files, check by check: the same outcome on all three test files of that return.

The rule in plain words

In Group solvency: information on affiliates of SDDTs (GS SDDT) (SC06.02.01.01): "Total risk exposure amount" (column 0250) must equal the sum of "Credit; counterparty credit; dilution risks, free deliveries and settlement/delivery risk" (column 0260), "Operational risk" (column 0280) and "Other risk exposure amounts" (column 0290).

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  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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 SC06.02.01 as reported.
  6. 06This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

The Bank’s own words and formula

[boe_b0080_ss];[{t: SC06.02.01.01, c: 0250} = {t: SC06.02.01.01, c: 0260} + {t: SC06.02.01.01, c: 0280} + {t: SC06.02.01.01, c: 0290}]
