The book is aimed at students of corporate accounting and controlling. Through numerous exercises and case studies, it deepens the learning content of the textbook "Internal Corporate Accounting" by Ralf Ewert and Alfred Wagenhofer. Accordingly, examples from the areas of decision-making calculations, control calculations, and coordination calculations at various levels of difficulty are the focus. In addition to shorter problems assigned to the individual chapters of the textbook, the exercise book also includes extensive case studies on selected issues of internal corporate accounting. Sample solutions provide assistance in developing solutions and offer opportunities for review during independent work.
