Taking into account the standards of the Basel Accord, Operational Risk Modelling and Management presents a simulation model for generating the loss distribution of operational risk. It also examines a multitude of management issues that must be considered when adjusting the quantitative results of a comprehensive model.
The book emphasizes techniques that can be understood and applied by practitioners. In the quantitative portions of the text, the author supplies key concepts and definitions without stating theorems or delving into mathematical proofs. He also offers references for readers looking for further background information. In addition, the book includes a Monte Carlo simulation of risk capital in the form of a run-through example of risk calculations based on data from a quantitative impact study. Since the computations are too complicated for a scripting language, a prototypical software program can be downloaded from www.garrulus.com
Helping you navigate the tricky world of risk calculation and management, this book presents two main building blocks for determining how much capital needs to be reserved for operational risk. It employs the loss distribution approach as a model for calculating the risk capital figure and explains risk mitigation through management and management’s actuations.

Summary and Conclusion
Claudio Franzetti is the chief risk officer of Swiss Export Risk Insurance (SERV) in Zurich and president of Garrulus Enterprise Ltd. He has previously worked at Aon Resolution AG, Deutsche Bank, Swiss Re, and Iris AG.
This book outlines a complete and detailed description of one specific approach to modeling operational risk in accordance with Basel 2. However, the approach could easily be applied in the wider financial services sector. The author also offers some prototypical software to take you through the book’s example. … This book would be most useful for new entrants into the risk management arena, particularly in banking but also in financial services generally. For those thinking about operational risk for the first time, it would give some useful background and theory. For the more experienced in the operational risk field, it would serve better as a reference document.

In this book, Claudio Franzetti deals with operational risks such as those recently brought into focus through the financial crisis (especially in the banking industry) … [He] handles the subject almost entirely without mathematical proofs and theorems and finds simple explanations for complicated relationships. In addition, the rich literature list stimulates further reading.
