Interpreting the Reserve Date for Operational Loss Records

Summary

The document asks how to interpret the reserve date used when recording legal related operational losses for a bank’s operational risk model. The cited guidance requires using a date no later than the reserve date when such losses or exposures are included as model inputs, but the excerpt does not define that date.

The proposed interpretation draws on a separate Basel paper about pending losses, such as litigation, whose final financial impact is uncertain. Under that account, a bank records a legal reserve in its loss database and updates the amount if it later changes. The reserve date is therefore understood as the date that reserve is established. This is an inference from related guidance rather than a definitive definition in the cited passage, so institutions should verify the applicable regulatory wording and accounting practice before relying on it.

Key ideas

• Operational risk guidance sets a latest permissible date for recording legal related losses in model inputs.
• The cited passage does not define the reserve date.
• A related Basel discussion describes recording pending losses using a legal reserve and updating the amount as needed.
• The answer infers that the reserve date is when the legal reserve is first recorded.

One of the BCBS papers on operational risk says the following:

> Consistent with other operational risk losses, a bank should use a date no later than the date of reserve for including legal related losses/exposures as an input in its AMA model.

What is the date of reserve? The paper doesn't define it and I can't find anything on Google.

I think I've found the answer in another Basel paper. This second paper is talking about the treatment of pending losses (losses where the financial impact is not certain at this point e.g. litigation). They way to record these in the loss database is to take a "legal reserve" and record that amount, then adjust the recorded amount in the future if it changes.

So from this, I gather "reserve date" is the date the "legal reserve" (which as I understand it is allocating funds now for when this loss might be realized) is taken.
