How should we interpret and treat the negative loss adjustment within the total loss amount?
How should we treat the total loss amounts compared to the top loss events and the max single loss?
There are some validation rules which say that the ‘total loss amount’ should be higher or equal to the ‘sum of the five largest losses’.
However, following the instructions, the total loss amount should be the sum of positive loss adjustment but also the negative loss adjustment due to decrease of provisions (see here below). The total loss can then be lower than the top five largest losses.
The Annex 2 of EC Implementing Act on Reporting states the following:
The Total loss amount is the algebraic sum of the following elements:
We have also another difference in the interpretation for the ‘total loss’ vs the ‘max single loss’. In some cases it is possible that the total is smaller than the maximum single loss and / or the Top 5.
For example:
As a consequence, the total loss is lower than the maximum single loss, which is possible, but not allowed by several validation rules.
Validation rules to be reviewed:
The validation rules v4864_m to v4882_m postulate that the total loss related to operational risk events is higher or equal to the maximum single loss and the sum of the five largest losses. Most commonly, this is the case. However, in situations of significant negative loss adjustments the opposite may occur. Although these cases are expected to be rare and validation rules v4864_m to v4882_m could serve as a trigger for a check of the values, these rules will be deactivated. |
