This research aims to give empirical evidence to prove whether the adoption of IFRS affect the relationship between analyst coverage and earnings management. This research includes 4 years period data sample on company in ASEAN 5 countries (Singapore, Malaysia, Philippines, Indonesia and Thailand). The result shows that (1) analyst coverage can curbs earnings management behavior in both types of earnings management. This demonstrates the ability of the analyst in the external mechanisms of corporate governance. (2) IFRS adoption can curbs earnings management through above-the-line items (ALIEM), but had no significant effect on earnings management through below-the-line items (BLIEM). (3) Contrary to expectations, there is no difference in the effect of analyst coverage on both types of earnings management in the period before and after the adoption of IFRS. This may be due to financial analysts have better skills and more resources, when compared to other users in the use of the financial statements. So it may be, without the adoption of IFRS, the analyst can use their analysis capabilities in using and understanding the financial statements.
