Off-balance sheet items - general: a total must equal the sum of its parts (IR.03.01, Bank of England rule IR_bv0612_01)

A blocking check on the off-balance sheet items - general template (IR.03.01), in the annual solo (ARS) return.

Check your file for this ruleWhat to do if it fails

The rule in plain words

The item "Total Contingent liabilities" reported in Off-balance sheet items - general (IR.03.01.01.01) should be equal to the sum of "Contingent liabilities not in Solvency II Balance Sheet" and "Contingent liabilities in Solvency II Balance Sheet"

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  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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 IR.03.01 as reported.
  6. 06This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

A worked example

With simple numbers.

Illustrative values
Contingent liabilities not in Solvency II Balance Sheet1,200
Contingent liabilities in Solvency II Balance Sheet800
Together2,000
What the rule then expects

Total Contingent liabilities 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.
