Abstract
AbstractThe progression of a corporation from a status of financial stability into the status of financial distress usually happens over relatively large periods of time, raising the opportunity of identifying these ‘falling’ corporations ahead of time. Consequently, a critical risk management objective is to provide investment portfolio managers with an early notice of deteriorating financial status for a corporation. We consider a model built using equity inferred Probability of Default (PD) metrics. We follow a Design for Six Sigma Define, Measure, Analyze, Design, Verify (DMADV) approach to enhance the predictability power of the PD by constructing a two‐dimensional risk space for estimating likelihood of default. We use such techniques as classification and regression tree (CART) analysis and logistic regression, and build a control plan using censored data analysis. We test our model on two actual portfolios. The potential savings revealed by these tests are significant, re‐assuring us of the performance of our methodology.
