"Total HQLA" must equal the sum of "Cash", "Level 1 Tradable assets", "Level 2A Tradable Assets" and "Level 2B Tradable Assets" (CL66.01.01.06, CL66.01.01.02, Bank of England check boe_b2018_m)

A warning on the PRA110. HQLA and usable liquidity. Initial Stock. Total (CL66.01.01.06) and PRA110. Initial stock. Total (CL66.01.01.02) templates, 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 "Initial stock" (column 010) of PRA110. HQLA and usable liquidity. Initial Stock. Total (CL66.01.01.06): "Total HQLA" (row 7370) must equal the sum of "Cash" (row 7380), "Level 1 Tradable assets" (row 7390), "Level 2A Tradable Assets" (row 7400) and "Level 2B Tradable Assets" (row 7410).

What to do if your return fails it

  1. 01Open the tables 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  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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.

A worked example

With simple numbers.

Illustrative values
Cash, Initial stock1,200
Level 1 tradable assets, Initial stock800
Level 2A tradable assets, Initial stock450
Level 2B tradable assets, Initial stock300
Together2,750
What the rule then expects

Total HQLA, Initial stock must then be 2,750.

2,750Passes
2,850Fails

A file that reports 2,750 passes. One that reports 2,850 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
