Query: A Definitive Manual for M&A Transactions

If you only were allowed to have one book on this subject in your library, this is the one that you want. It gives good coverage to all of the important topics needed to evaluate, price and execute a transaction. The footnotes at the end of each chapter are an excellent reference. It also benefits from a very detailed index. The Q&A format of the text is a bit unusual for a work of this type, but is actually quite useful when browsing or quickly finding the key theme of each paragraph or section. It also contains a good selection of sample documents and checklists. Overall, it delivers a lot of high quality information the investment banking professional can really use.
