The IFRS practice book offers a wide range of tested, practical exercises and cases with detailed solutions. Each task is accompanied by a learning objective formulation and a difficulty level. The difficulty levels cover the knowledge spectrum from the beginning of engagement with IFRS to the auditor's exam. This makes the practice book very suitable for self-study and it can be combined with relevant textbooks and manuals. In the fourth, completely revised edition, numerous new tasks have been added, while less relevant ones have been omitted. For the first time, the new consolidation standards IFRS 10 to IFRS 12 have been specifically taken into account.
