I have a copy of this book. It covers popular credit risk models and things like RAROC, etc. These concepts have been discussed extensively in the industry but I assume this is the first in the book form. The book does a good job in presenting basic ideas. However, if you are looking for technical details, you best bets are still the original technical documentations (CreditMetrics, CreditRisk+, KMV, etc). Nevertheless this book is a useful survey of the current stable of models. Besides, it is not very expensive.
