In this paper three different rating migration models are implemented by means of real financial data. The models consider alternative hypotheses in order to manage the rating class NR (no rating).

Abstract

In this paper three different rating migration models are implemented by means of real financial data. The models consider alternative hypotheses in order to manage the rating class NR (no rating). Rating transition probabilities, default probabilities and the firm survival functions are, among all proposed indicators, the most important. They are evaluated for each of the three models. Data refers to long-term ratings from Standard & Poor's historical file, from 1975 to 2007. The mathematical tools used are, semi-Markov and backward recurrence time processes.
