PRA110. Monetisation Actions. Total: a total must equal the sum of its parts (CL66.01.01.05, Bank of England check boe_b2028_7_m)

A warning on the PRA110. Monetisation Actions. Total template (CL66.01.01.05), in the liquidity pillar II (PRA110) return.

Line4 Check runs it on the liquidity pillar II (PRA110) return, proven on test files, check by check: the same outcome on all three test files of that return.

Check your file for this ruleWhat to do if it fails

The rule in plain words

In column "Greater than 5 days up to 6 days" (070) of PRA110. Monetisation Actions. Total (CL66.01.01.05): "HQLA Securities monetised via new secured financing transactions" (row 7290) must equal the sum of "Level 1 Tradable assets" (row 7300), "Level 2A Tradable Assets" (row 7310) and "Level 2B Tradable Assets" (row 7320).

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  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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 CL66.01.01 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.

What the rule then expects

HQLA Securities monetised via new secured financing transactions must then be 2,450.

2,450Passes
2,550Fails

A file that reports 2,450 passes. One that reports 2,550 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

The Bank’s own words and formula

The plain words above spell out the Bank’s formula, with each cell named from its templates. In the Bank of England’s list of validations, word for word:

boe_b2028_7_m: T1: CL66.01.01.05; Expression: {CL66.01.01.05, r7290, c070} = {CL66.01.01.05, r7300, c070} + {CL66.01.01.05, r7310, c070} + {CL66.01.01.05, r7320, c070}
