RESUMO
Measuring the fair default risk for a company, has always been a crucial task for a financial institution when it comes to granting loans, especially nowadays, with the rise in competitiveness and the reduction of the spreads. On the other hand, companies need to be analytical and must know how to determine their level of risk with the same accuracy as the financial institutions. Every market agent must possess the best tools to measure the credit risk, and with this purpose, the most discussed subject of the moment will be presented in this dissertation. The focus will be on the theoretical model of equilibrium by Merton, 1974, which was widely spread by KMV Corporation, who developed a model based on Merton`s premises in order to be able to predict default. The dissertation will start with an approach over the scenario that led to the development of new models to quantify the credit risk. Next, a review over the KMV model and the DLI model (based on Merton, 1974) will be done. After that, we will estimate the asset value starting from the equity value, and calculate the probability of default of Brazilian companies that are negotiated on the stock exchange, and who`ve really gone into default. We will discuss the advantages and disadvantages presented by these two models and the existing difference between the KMV and the DLI models.
