Article 39
Human judgement
When assessing whether the statistical model or another mechanical method is complemented by human judgement in accordance with Article 174(e) of Regulation (EU) No 575/2013 and whether human judgement is applied in a proportionate and adequate manner in the development of the rating model and in the process of assigning exposures to grades or pools, competent authorities shall verify that:
(a) |
the manner in which human judgement is applied is justified and fully documented and that the impact of human judgement on the rating system is assessed, if possible also by means of a computation of the marginal contribution of human judgement to the performance of the rating system; |
(b) |
all relevant information not considered in the model is taken into account and an adequate level of conservatism is applied; |
(c) |
where the process of assignment of exposures to grades or pools in a rating system requires the application of human judgement in the form of subjective input data or where the credit policy allows for overrides of inputs or outputs of the model, all of the following applies:
|
(d) |
the application of human judgement is appropriately managed and proportionate to the type of exposures for each rating system. |
