Abstract

We consider an enhancement of the credit risk + model to incorporate correlations between sectors. We model the sector default rates as linear combinations of a common set of independent variables that represent macro-economic variables or risk factors. We also derive the formula for exact VaR contributions at the obligor level. Copyright Springer-Verlag 2009
