(26)Institutions’ exposures to other institutions, other financial sector entities and large corporates typically exhibit low levels of default. For such low-default portfolios, it is difficult for institutions to obtain reliable estimates of the loss given default (LGD), due to an insufficient number of observed defaults in those portfolios. That difficulty has resulted in an undesirable level of dispersion across institutions in the level of estimated risk. Institutions should therefore use regulatory LGD values rather than internal LGD estimates for those low-default portfolios.
