This worksheet captures all operational risk loss events in the operational risk loss data system since its inception. Therefore, the template must also include loss events that have already been submitted in previous STDF submissions. The Unique ID is used to make sure that any updates to a particular loss event (e.g. gross operational loss) in the future can be traced back to the original event and the corresponding details amended. The collection only collects the residual losses not collected in FSA073, we expect firms to still submit as per the regulatory request.
