Have the Moroccan National Accounting Council and Academics Researchers Overestimated the Benefits of Adopting IFRS?

Purpose: In Morocco, the opening to IFRS standards was made in 2007 through the obligation made to the new rules will allow financial institutions to publish their consolidated financial statements in accordance with international accounting standards. The adoption of IFRS accounting standards has the effect of increasing the relevance of accounting and its usefulness to stakeholders. However, the adoption of these standards often emanates from the requirements of international financial institutions which impose the "IFRS label" to align with the best practices of developed countries. Following on from the question asked by Christensen in 2012, have the Moroccan National Accounting Council and academics researchers overestimated the benefits of adopting IFRS?Design/Methodology/Approach: Based on the price and yield model developed by Amir et al (1993) our study focuses on the effects of IFRS on the relevance of financial reporting in Morocco.Findings: The results show that the adoption of IFRS does not bring value relevance compared to national accounting standards. The coefficients of determinations are low. Implications/Originality/Value: This study presents a scientific and managerial contribution on several levels. Indeed, for financial managers, accountants, and shareholders of listed companies, the implementation of IFRS does not have a significant impact on the quality of accounting figures. That being said, national accounts are as relevant in terms of quality as IFRS. It may be necessary to invest in other projects such as the modernization of accounting information systems to better manage financial reporting.
