Note 12 - Credit risk exposure for each internal risk rating
The Bank uses a special classification system for monitoring credit risk in the portfolio. Risk classification is based on each individual exposure's probability of default. In the table below this classification is collated with corresponding rating classes at Moody’s.
Historical default data are Parent Bank figures showing the default ratio (DR) per credit quality step. The figures are an unweighted average of customers with normal scores in the period 2011-2017.
Collateral cover represents the expected realisation value (RE value) of underlying collaterals. The value are determined using fixed models, and actual realisation value are validated to test their reliability of the model. In accordance with the capital requirements regulations the estimates are downturn estimates. Based on the collateral cover (RE value / EAD) the exposure is classified to one of seven classes, the best of which has a collateral cover above 120 per cent, and the lowest has a collateral cover below 20 per cent.
