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.
