Modern cash management is no longer restricted to the management of business cash flows and account balances. Often, a cash manager works closely with the treasurer and ears responsibility for the management of short-term interest rate and foreign exchange risks as well as some of the company's corporate finance operations and a number of core tasks. A cash manager plays an important supporting role in the company's working capital management. Since the credit crunch, the environment has changed and the strategic aspects of a cash manager's function have become much more important. However, the significance and relevance of their overall activities remains unchanged. This fourth edition of the book again provides a fully updated overview of the position and duties of the modern cash manager in an international company. It deals with the most important instruments used in contemporary cash management. And of course, attention is paid to new techniques relevant for cash management, such as blockchain technology. It covers a cash manager's regular duties, including the daily management of account balances and the conclusion of transactions in the financial markets. Examples are presented of several types of cash flow forecasts and an overview is given of all relevant financial products. Furthermore, extensive attention is devoted to the establishment of a proper cash management infrastructure for the company. This includes setting up an (international) account structure, cash pools (international or otherwise), payment and collection factories and a netting system. Finally, a description is provided of the cash man- ager's role as a company adviser in relation to the management of its working capital. There is also new content concerning best practices in specific regions. The book is intended primarily for current and future professionals in the corporate treasury and banking sectors who wish to gain practical knowledge of the subject. It is also suitable for students who need a broad general overview of cash management as part of their business economics and administration studies.
