This study aims at investigating the impact of the IFRS (15) on the quality of accounting information in terms of relevance and faithful representation. To achieve the study objectives, a questionnaire is designed and distributed randomly on the study sample which includes (100) of external auditors of the Big Four audit companies in Jordan using the descriptive analytical approach. The study hypotheses are tested through the Simple Regression Test and the One Sample T- Test. The study results indicate a statistically significant impact of the implementation of the IFRS 15 on improving the quality of accounting information from the perspective of external auditors at the Big Four audit companies in Jordan. Moreover, the study finds that there is a statistically significant impact of the implementation of the IFRS 15 on improving the relevance and faithful representation of accounting information included in the reports. Moreover, the study findings also show that Jordanian companies face statistically significant difficulties for the implementation of standard 15 when preparing their financial statements. The researchers have also reached many recommendations; the most important of which suggest to inform investors and other decision makers of the results of the study to help them rationalize their investment decisions and raise their awareness about IFRS 15.

One of the primary concerns on stock market is the risk associated with securities. There are different attempts devoted to detect and reduce any existing risk and provide necessary action to reduce them as much as possible. In this paper, we study the relationship between quality of earnings and systematic risk as well as cost of capital. The proposed study of this paper uses the information of 150 firms listed on Tehran Stock Exchange and using multiple regression technique examines two hypotheses based on yearly information over the period 2006-2010. The results of our survey indicate that as the quality of earnings increase, the risk as well as the cost of capital decrease.
