Alternative treatment of the exposure measure (LR1): the value of this exposure should be greater than or equal to zero (LV40.00.00.01, Bank of England check boe_b0002)

A warning on the alternative treatment of the exposure measure (LR1) template (LV40.00.00.01), in the leverage ratio (LVR001) return.

Line4 Check runs it on the leverage ratio (LVR001) return, proven on test files, check by check: the same outcome on all eight test files of that return.

The rule in plain words

The value of this exposure should be greater than or equal to zero.

In Alternative treatment of the exposure measure (LR1) (LV40.00.00.01): every value in 8 rows (listed below) in column "Accounting balance sheet value" (column 0010) must be zero or more.

What to do if your return fails it

  1. 01Open the table below and find the cells the rule reads.
  2. 02Look for a value below zero in these cells, such as an amount entered as a negative number.
  3. 03It runs only when your filing indicators mark LV40.00.00 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.
