Abstract

The main purpose of the paper is to estimate the effect of mandatory adoption of International Financial Reporting Standards (IFRS) on the relationship between market-based measured of risk and acconting variables using a sample of banks are listed on the Theran stock exchanges that covers pre-IFRS and post-IFRS periods201۵-2017,in order to examine whether IFRS introduction enhaces the systematic and nonsystematic risks.Employing pearson correlation coefficient and paired –samles t test and the Fisher r-to-z transformation , our finding show that the adoption IFRS reinforces positive association between loans to assets ratio with systematic risk while credity and size  with systematic and nonsystematic risk and conservatism and EPS with systematic risk are inversely related under IFRS. In addition, the relationship between income diversification and market measures of risk is satistically significate after the adoption IFRS, than earning par share are inversely related with systematic risks. Finally IFRS didn’t has any effect in the relationship  between liquidity and systematic and nonsystematic risks.The evidence supports the findings for European companies and thus points to the benefits potentially available to companies in countries that have yet to adopt IFRS .Our findings highlight the effects of mandatory adoption IFRS in iranian banks so we suggest to reduce systematic risks in other companies , IFRS will be initially adopted voluntarily .
