Commercial bankers, investment bankers, financial lawyers, finance professors, and (at least) one accountant who were in on the creation of credit derivatives during the mid-1990s author chapters that are non-mathematical. (Well, I guess Harvard Business School Professor Sanjiv Das's credit derivatives pricing chapter is kind of mathematical.) Each chapter author is expert in the aspect of credit derivatives about which they write. Every commercial banker in the world should read up on this subject.
