Does the IFRS improve earnings quality? A comparison of Turkish GAAP and IFRS

Purpose - The purpose of this study is to reveal the effect on earnings quality of switching to International Financial Reporting Standards (IFRS) from Turkish generally accepted accounting principles (GAAP) by comparing two sets of financial statements based on Turkish GAAP and IFRS. Design/methodology/approach - This study is based on mathematical modeling. The variables (total assets, net income, total accruals, cash receivables, return on assets and size) in the models are core to the quantitative research that examines the relationship between them. In this study, the total accruals are computed based on the indirect approach, and the prediction error of the model represents discretionary accruals that reflect earnings management. The data set includes financial data prepared under IFRS and Turkish GAAP. The univariate and multivariate analyses are conducted by SPSS. Findings - The results of this study indicate that IFRS does not cause any significant differences in total assets, but the net income under IFRS is larger compared to that under the Turkish GAAP. It is also found that while there is no significant difference in total accruals, there is a difference in discretionary accruals. In other words, Turkish firms use income-reducing discretionary accruals when adopting IFRS. Originality/value - This study provides more insights into the effect of IFRS on earnings quality. It also provides evidence of the effect of accounting culture on IFRS adoption. As a code-law country in Turkey, publicly traded firms have to prepare financial statements based on both Turkish GAAP, which is rule-based and restricts management decisions with strict rules, and the principle-based IFRS which leaves more room to manipulate. To the authors’ knowledge, this is the first study that reveals the effect of accounting standards on earnings management by comparing two sets of financials of the same period prepared under different standards.
