Berk and DeMarzo's_ Corporate Finance_ uses a unifying valuation framework, the Law Of One Price, to present the core content instructors expect, the new ideas they want, and the pedagogy their students need to succeed.    _Corporate Finance: The Core _fits programs and individual instructors who desire a streamlined book that is specifically tailored to the topics covered in the first one-semester course. For instructors who would like to use a text in a two semester, or more, sequence, please see _Corporate Finance,_ the 31 chapter book also by Jonathan Berk and Peter DeMarzo.
