The rule in plain words

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

In (LR4) Alternative breakdown of leverage ratio exposure measure components: Other non-trading book exposures (SA) (LV43.00.00.02): every value in 25 rows (listed below) in "Leverage Ratio Exposure Value: SA Exposures" (column 0010) and "RWEA: SA exposures" (column 0030) 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 LV43.00.00.02 as reported.
  4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
