Objective - The Indonesian Accounting Standard Authority has required companies to adopt the International Financial Reporting Standard (IFRS) since its adoption in 2012. The new standard emphasizes relevance, while the previous standard focused on conservative issues. While the IFRS does not specifically aim to reduce conservatism, this aspect is no longer the emphasis of the new standard. There are concerns about whether the IFRS reduces conservatism and the research on this issue are still uncertain. Hence, this study aims to determine the level of conservatism in the period following the adoption of the IFRS. The study also aims to examine the outcome of the adoption of the IFRS since its adoption in Indonesia in 2012. Methodology/Technique - Using the accounting conservatism model developed by Basu (1997), the authors compare firm conservatism before and after the adoption of the IFRS. The sample includes companies listed on the Indonesian Stock Exchange between 2006 and 2016. There are 3.742 firm-years that consist of 394 companies from various industrial sectors. The data is analyzed using a Pooled Least Square method. Findings - The results show that conservatism was high prior to the adoption of the IFRS. Further, accounting earnings are more sensitive to the negative return than to the positive return before the adoption of the IFRS. However, in the post-adoption period, sensitivity to negative return has decreased. This means that the adoption of the IFRS has reduced levels of conservatism. The Indonesian Accounting Standard Authority may rely on these results to evaluate the mandatory policy of IFRS. Novelty - This study explores the prevalence of conservatism within firms prior to, and following, the adoption of the IFRS using longitudinal data.

Objective - The adoption of IFRS aims to reduce the level of information asymmetry. Prior studies conducted in developed countries prove that the adoption of IFRS enhances transparency and diminishes information asymmetry. However, in developing countries with a low level of openness, limited regulation, and more centralized ownership, the ability of IFRS to reduce information asymmetry remains unknown. To address this issue, this study aims to investigate whether IFRS adoption will reduce information asymmetry in some developing countries in South East Asia. Methodology/Technique - This research is applied in three developing countries: Indonesia, the Philippines and Thailand. Information asymmetry is proxied by the cost of capital using the Easton model (2004) and a bid-ask spread. Listed firms from the three countries are selected as the research sample resulting in 5.313 firm-years for the period between 2007 and 2016. Findings - This study concludes that the adoption of the IFRS decreases information asymmetry in developing countries. These finding confirm that the benefit of the adoption is the same as in developed countries, despite the level of law enforcement in developing countries being lower. Managers, standard authorities and investors must note that the IFRS conveys benefits to the market, which increases transparency by asking lower returns and valuing company stocks appropriately. Novelty - This study examines the benefits of the adoption of the IFRS in reducing information asymmetry in some emerging countries to enhance the generalization of the results from prior studies that are mostly conducted in developed countries.
