Structured products are complex instruments the payoffs on which depend on the performance of pools of correlated underlying assets and that possess a tranche structure, i.e., a set of rules that prescribe how cash flows on the underlying pool are split between the holders of several classes of claim of different seniorities. This paper describes a methodology we have developed for calculating ratings-based capital charges for structured products like structured exposures. The model we employ is a generalization of industry-standard, ratings-based credit portfolio models.
