Part 3: Detail of the exposures to intragroup counterparties (entity breakdown): "Total original exposure" must equal the sum of 13 columns (SR801.03.01.01, Bank of England check boe_v1677_m)

A blocking check on the part 3: Detail of the exposures to intragroup counterparties (entity breakdown) template (SR801.03.01.01), in the intragroup exposures (RFB001) return.

Line4 Check runs it on the intragroup exposures (RFB001) return, proven on test files, check by check: the same outcome on all eight test files of that return.

The rule in plain words

In Part 3: Detail of the exposures to intragroup counterparties (entity breakdown) (SR801.03.01.01): "Total original exposure" (column 050) must equal the sum of 13 columns (listed below).

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  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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 SR801.03.01 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_v1677_m: T1: SR801.03.01.01; Expression: {SR801.03.01.01, c050} = sum({SR801.03.01.01, c070-190})
