A blocking check on the intragroup financial reporting (detailed breakdown) Asset management, custody and other service functions Part 2: Assets involved in the services provided template (SR22.02.04.01), in the intragroup financial reporting (core and detailed breakdowns) (RFB004) return.

Line4 Check runs it on the intragroup financial reporting (core and detailed breakdowns) (RFB004) return, proven on test files, check by check: the same outcome on all eight test files of that return.

Check your file for this ruleWhat to do if it fails

The rule in plain words

In column "Amount of the assets involved in the services provided to other group entities" (column 0010) of Intragroup financial reporting (detailed breakdown) Asset management, custody and other service functions Part 2: Assets involved in the services provided (SR22.02.04.01): "Custody assets [by type of customer]" (row 0060) must equal the sum of "Collective investment" (row 0070) and "Other" (row 0080).

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  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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 SR22.02.04 as reported.
  6. 06This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

The cells it reads

Rows

  • R0060Custody assets [by type of customer]
  • R0070Collective investment
  • R0080Other

Column

  • C0010Amount of the assets involved in the services provided to other group entities

A worked example

With simple numbers.

Illustrative values
Collective investment1,200
Other800
Together2,000
What the rule then expects

Custody assets [by type of customer] 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.

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

{t: SR22.02.04.01, r: 0060} = {t: SR22.02.04.01, r: 0070} + {t: SR22.02.04.01, r: 0080}

Where it applies, in the Bank's words (its scope):
