The rule in plain words

The total amount of exposures treated as sovereigns should be equal to the sum of the values in r0100, 0110, 0120 and 0130 of this column.

In each of "Leverage Ratio Exposure Value: IRB Exposures" (column 0020) and "RWEA: IRB exposures" (column 0040) of (LR4) Alternative breakdown of leverage ratio exposure measure components: Other non-trading book exposures (IRB) (LV43.00.00.03): "Exposures treated as sovereigns" (row 0090) must equal the sum of "Central governments and central banks" (row 0100), "Regional governments and local authorities treated as sovereigns" (row 0110), "MDBs and international organisations treated as sovereigns" (row 0120) and "PSEs treated as sovereigns" (row 0130).

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  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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 LV43.00.00.03 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.

The Bank’s own words and formula

The first paragraph of the plain words above is the Bank of England’s own, word for word, from its list of validations. The second spells out its formula, with each cell named from its templates.

The Bank of England's formula. Cells are written as {t: table, r: row, c: column}.

{t: LV43.00.00.03, r: 0090} = sum({t: LV43.00.00.03, r: 0100; 0110; 0120; 0130})
