A MERTON-MODEL APPROACH TO ASSESSING THE DEFAULT RISK OF UK PUBLIC COMPANIES.

This paper shows how a Merton-model approach can be used to develop measures of the probability of failure of individual quoted UK companies. Probability estimates are then constructed for a group of failed companies and their properties as leading indicators of failure assessed. Probability estimates of failure for a control group of surviving companies are also constructed. These are used in probit regressions to evaluate the information content of the Merton-based estimates relative to information available in company accounts and in assessing Type I and Type II errors. We also look at power curves and accuracy ratios. The paper shows that there is much useful information in the Merton-style estimates. [ABSTRACT FROM AUTHOR]
