Abstract:The BIS 2001 opened the door to the possibility of using, subject to validation by the individual national supervisory authorities, systems of internal rating of credit risk developed by the banks when they satisfy certain criteria. Specifically, the Basel Committee proposed two approaches to the internal rating of credit risk -the 'foundation' and 'advanced' approaches. As such, there is a different degree of bank "autonomy" in the estimation of the parameters relevant to determining the risk weighting and thus to capital adequacy: there is lesser autonomy in the case of the 'foundation' approach and greater autonomy in the 'advanced' version. This paper presents a compound credit risk modelling approach for private firms which fulfil 2001 Basel Accord requirements in the case of the adoption of the foundation approach. We present findings from applying this model to a large sample of client firms of the Bank of Rome.
