Companies spend more than $2 trillion on mergers and acquisitions (M&A) every year, yet over 70 percent of these growth measures fail. Some even lead to bankruptcy of the acquiring company. The reason for this often is because managers have not enough experience with the acquisition process and make acquisitions for the wrong purpose. The Fundamentals of Mergers & Acquisitions module offers a systematic and profound foundation for preparing and executing transactions in real life. The forms and methods of various deal types are explained in depth and examples for each category are provided. For the M&A process we discuss step-by-step what it takes to acquire or sell businesses as well as the different roles people play (as internal staff or external advisors) and how to orchestrate them. The motivations and reasons why companies or investors get involved in deal making can be quite different but should be grounded in M&A strategies where the different options and tools are elaborated. As M&A activity is rather volatile we explore the historical development and key drivers with a perspective to understand the optimal timing for arranging great deals. In the introduction to Due Diligence, the most important aspects and fields that should be covered in transactions are covered. Finally this modules provides and introduction to the most important ways how to evaluate companies.
