International accounting standards help businesses worldwide communicate better by harmonizing financial reporting practices. The European Union has made significant progress in this area with Directives IV and VIII. International Accounting Standards (IAS) and International Standards of Auditing (ISA) play a key role in improving accounting communication between global enterprises. International Financial Reporting Standards (IFRS) ensure high-quality financial reports, reliable auditing, and better accounting practices, promoting harmonization in international business. To achieve this harmonization, corresponding legal regulations may be necessary in some countries where the use of IAS is not currently feasible.
