Abstract: This book is a primer on corporate law for law students and anyone else desiring a first course in corporate law. The book provides a self-contained, accessible presentation of the field’s essentials: what corporations are, how they are governed, their interactions with their investors and other stakeholders, major transactions (M&A), and parallels with alternative entities including partnerships; optional background chapters cover the investor eco-system, corporate governance, and corporate finance. The book’s exposition of doctrine and policy is nuanced and sophisticated yet short and simple enough for a quick read.
