Dynamics Of The Fair Value In Accounting

Until now, the historical cost principle has dominated accountancy. At this time, another princi-ple seems to operate: the fair value principle. The discussion will gravitate around the questions: What is fair value? How has concept of fair value evolved? How much is the fair value used as the ba-sis for measurement in IFRS? Are we moving towards a full fair value? In conditions of economic crisis, the measurement at fair value offers pertinent information? To answer at these questions, we have realized by one hand, a description of the manner which the notion of fair value evolved and in the other hand, a deep IFRS analysis which use fair value in assets and liabilities evaluation. As a re-sult of this study, it seems that the most of the assets and liabilities need to be measured at fair value or they may be measured at fair value, if the entity chooses this accounting treatment.
