This article is focused on the interdependencies between corporate governance and controlling from a German perspective. An impact analysis based on the area of auditing, supervision and control will follow. Using the example of intangible assets and long-term manufacturing contracts according to IFRS, the influences of internationalisation on controlling will be presented. The details show that the development of financial accounting into an integral business reporting system together with an increase in importance of controlling goes hand in hand. In the future, controlling will form the central link between corporate governance and business reporting.
