Article 47
Length of the historical observation period
When assessing the length of the period used for LGD estimation for the purpose of point (j) of paragraph 1 and subparagraph 2 of paragraph 2 of Article 181 of Regulation (EU) No 575/2013 and Delegated Regulation (EU) 2017/72, (‘historical observation period’), competent authorities shall verify that:
|
(a) |
the length of the historical observation period covers at least the minimum length in accordance with the requirements laid down in paragraph 1(j) and the second subparagraph of paragraph 2 of Article 181 of Regulation (EU) No 575/2013 and, where applicable, Delegated Regulation (EU) 2017/72; |
|
(b) |
where the available historical observation period is longer than the minimum period according to point (j) of paragraph 1 of Article 181 and subparagraph 2 of paragraph 2 of Article 181 of Regulation (EU) No 575/2013 for a data source, and the data obtained from it are relevant for the LGD estimation, that the information for that longer period is used; |
|
(c) |
for retail exposures, where the institution does not give equal importance to all historical data used, that this is justified by better prediction of loss rates and that a zero or very small weight applied to a specific period is either duly justified or leads to more conservative estimates. |
