Prudent valuation: core approach - Pre and post diversification (PRUVAL 2): a conditional check (C32.02.01.01, C32.02.01.03, Bank of England check v10697_m)

A warning on the prudent valuation: core approach - Pre and post diversification (PRUVAL 2) (C32.02.01.01) and prudent valuation: core approach - Other (PRUVAL 2) (C32.02.01.03) templates, in the own funds (PRA001) return.

Line4 Check runs it on the own funds (PRA001) return, proven on test files, check by check: the same outcome on all three test files of that return.

The rule in plain words

Prudent valuation: core approach - Pre and post diversification (PRUVAL 2): a conditional check. The Bank's own words and formula below set it out in full.

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 tables below and find the cells the rule reads.
  2. 02The check applies only when its first part holds in your return. When it does, the second part must hold too: fix the second part, or correct the first.
  3. 03It runs only when your filing indicators mark C32.02.01 as reported.
  4. 04This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.
