Every value in 12 rows in "(-) Long" and "(-) Short" must be zero or less (OF20.00.01.01, Bank of England check v2057_s)

The rule in plain words

What to do if your return fails it

1. 01Open the table below and find the cells the rule reads.
2. 02Compare the values in your return. If the first is bigger than it may be, one of them is wrong: check both before you change either.
3. 03It runs only when your filing indicators mark OF20.00.01 as reported.
4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

The cells it reads

Which returns it applies to

Line4 Check runs it on the own funds (PRA001) return on Bank of England banking taxonomy 4.1.1. The Bank of England applies it to own funds (PRA001) returns, as a blocking check.

The Bank’s own words and formula

v2057_s: [OF20.00.01.01 (All rows, c0030;0040)] {OF20.00.01.01} <= 0
