A First Course in Corporate Finance

by Ivo Welch
The only meaningful constraint that I am imposing for permittingdownloads is that you must not be currently involved in writing orpublishing a finance textbook. If you are, please exit this site now.(If you are not, you can freely read this book; reading or registeringwill not prevent you from writing a book in the future.)

    * Based on numerical examples, with easy 1-to-1 formula correspondence.
    * Half the size of a traditional text --- less is more.
    * Conversational tone.
    * Closely tied and easily integrated into the finance curriculum.
    * Clean design --- not just another clone.
      (The book can serve not only as a substitute, but also as a complement to a traditional textbook.)
    * Many, many other innovations.
(Pro formas are the "capstone" chapter. There is a goodstand-alone chapter explaining financials from a finance perspective.Comparables are put into perspective. Capital structure reflects morerecent findings and is thus much more modern. WACC and APV and thedirect approach from financials have clear explanations. Robustness anderrors are emphasized throughout the book. The default premium and riskpremium are clearly distinguished from one another. There is oneintuitive CAPM explanation anyone can understand, and (in theinvestments book) a hands-on explanation so anyone will reallyunderstand it. There is an ethics chapter. The governance chapter ismore skeptical. And many more.)
