Abstract

Banks are exposed to different sources of risk which may affect its equity levels and profitability. The main risk approached is called ‘credit risk’, defined by the probability of a debtor to default with the agreed contractual terms. This risk allows us to quantify the expected loss regarding an individual credit, which depends on three different parameters: the probability of default (PD), the exposure at default (EAD) and the loss given default (LGD). The following study applies four econometric techniques to estimate the probability of default, namely, linear probability model, logit, probit and multiple discriminant analysis. The sample collected covers 200 mortgage residential loans, originated between 2000 and 2010, including contracts affected by a default event during 2011 and contracts free of default event during the same year.
