The aim of this paper is to investigate theoretically one of the current models of credit portfolio management. There are currently three types of models to consider the risk of credit portfolio: the structural models (Moody's KMV model and CreditMetrics model) also defined by the models of the value of the firm, reduced form models also defined by models with intensity models (the actuarial models) and the econometric models (the Macro-factors model). The development of the three types of models is based on a theoretical basis developed by several researchers. The evolution of their default frequencies and the size of the loan portfolio are expressed as functions of macroeconomic and microeconomic conditions as well as unobservable credit risk factors, which explained by other factors. We developed this paper to explain the different characteristics of the CreditRisk+ models. The purpose of this model is to calculate the default probability of credit portfolio.
