This is the Total value of Interest Earning Assets calculated as the sum of each interest earning asset for the period (OF16.00.01.04, SC16.00.01.04, Bank of England check boe_b0468)

A warning on the operational risk: part 4 - business indicator and subcomponents (OPR) (OF16.00.01.04) and operational risk: part 4 - business indicator and subcomponents (OPR) (SC16.00.01.04) 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

This is the Total value of Interest Earning Assets calculated as the sum of each interest earning asset for the period

In each of "T-2" (column 0010), "T-1" (column 0020) and "T" (column 0030) of Operational risk: part 4 - business indicator and subcomponents (OPR) (OF16.00.01.04): "Interest earning assets" (row 0120) must equal the sum of 8 rows (listed below).

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  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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 OF16.00.01.04 as reported.
  6. 06This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.
