International Accounting Standards (IAS) are a set of guidelines and principles designed to ensure consistency and transparency in financial reporting across different countries. These standards help businesses prepare their financial statements in a way that is understandable and comparable, making it easier for investors and stakeholders to assess a company's performance. The International Accounting Standards Board (IASB) is responsible for developing and maintaining these standards. By adopting IAS, companies can enhance their credibility and facilitate international trade and investment, as these standards promote a common financial language that transcends national borders.
