The rule in plain words
In column "Amount" (0010) of Own funds (CA1) (C01.00.01.01): "Retained earnings" (row 0130) must equal the sum of "Previous years retained earnings" (row 0140) and "Profit or loss eligible" (row 0150).
What to do if your return fails it
- 01Open the tables below and find the cells the rule reads.
- 02Add up the parts in your return and compare the result with the total.
- 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.
- 04The Bank of England allows a small rounding difference, worked out from the decimals each value is reported with.
- 05It runs only when your filing indicators mark C01.00.01 as reported.
- 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.
Retained earnings must then be 2,000.
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.
Which returns it applies to
Line4 Check runs it on the own funds (PRA001) and own funds for SDDTs (PRA116) returns on Bank of England banking taxonomy 4.1.1. The Bank of England applies it to own funds for SDDTs (PRA116) and own funds (PRA001) returns, as a blocking check.
