Impact of IAS-IFRS on the communication and financial information of SBF 120 companies.

Summary IFRS are the accounting standards to which all companies listed on a European market must adhere as of January 1, 2005 for the presentation of their consolidated accounts. The purpose of this research is to study the impact of the transition to IFRS on the communication and financial information of SBF 120 companies. Thus, we constructed a voluntary disclosure score and studied the evolution of the financial communication of SBF 120 companies in the pre/post IFRS period. The results show an increase in the amount of voluntary disclosure by companies. The second part of the thesis is devoted to the analysis of the quality of this financial communication. The results of the test thus conducted reveal a decrease in the asymmetry of information at the end of the transition to IFRS and thus confirm the qualitative nature of the voluntary disclosure score previously calculated.
