Many books exist about analyzing the different financial derivatives to hedge currency - or interest rate - or commodity - risks. For the same purpose exist a lot of books with the numeric analysis of derivatives and of the different option - price - formulas. There exist also many accounting books how to book such transactions. All this together is the basis for the present book. The book on hand contain the analysis of the 20 biggest, listed European companies outside the Euro - Zone with regard to their currency-, interest rates- and commodity risk management. Here one could find names like BHP, BP, Diageo, Nestle, Novartis, RioTinto, Roche, RoyalDutch and Vodafone. The main focus is to reveal the typical mistakes and to calculate the dimension of the mistakes within the currency and derivative management. Therefore the IFRS balance sheets of each group of the years 2007 - 2014 were analyzed. Within the analysis the main focus were to the balance positions of the Translation - risk, Fair Value Hedge, Cash-Flow Hedge and all derivatives without documented hedge relation. The analysis results will surprise. Because of IAS 39, IFRS 9 in connection with IFRS 7 these groups have to give the information about the use and extent of financial derivatives. This analysis was pursued with special interest because the balance rules with regard to the Translation - risk do not considering the economic studies about the predicted future currency developments. It seems that the Translation - risk is essential underestimated.
