Thank you for taking the time to read this book. We have put countless hours and enormous effort into creating something we hope will be useful for you. Read this book all the way through, and then when you are done using it as a tutorial you can keep it around as a reference. Auditing is a detail-oriented job, and it is easy to get over-whelmed and overlook something. In addition, it is very easy to get in over your head. This book is a great place to start, learn, and expand on what you know. We hope you enjoy reading this book as much as we did writing it. Good luck in all your audits.
