Title: The Best of the Enron Books Review: As a former energy merchant employee and power/gas deal structurer who watched the collapse of Enron and so many others in the industry from the "inside," this text gives accurately portrays key features to Enron's demise: (1) the amazing and ingenius personalities involved, (2) the development of a complex industry, (3) political, market, regulatory, and accounting/tax dynamics that enabled and facilitated manipulation, and (4) unstoppable greed.I concur when several other readers when they point out that this text is dense and highly technical. This Enron book is best suited for those who already have a background the energy, financial, and trading industry. If the terms "stack and roll," "Henry Hub," "take or pay," or "back-to-back" are foreign to the reader, the book may seem tedious and boring. If the above terms are familiar and sources of interest, this book is for you. Answer:
output: Yes
