Based on legal documents and standards about materiality and audit performance in force in both regions, them being Russian Accounting Standards and International Financial Reporting Standards as well as International Audit Standards, and companies’ financial data, the research reveals significant differences in materiality reporting and discusses how they may affect the economy and international trade. Further to emphasizing the importance of harmonized reporting standards, this paper recommends the harmonized financial reporting in view of comparing the Oil and Gas trade between regions.engMaterialityRussiaEuropeAuditingAuditorAccounting standardsOil and gas companiesmaster thesis203906268
