This paper investigates the financial disclosure practices of corporate annual reports published in Asian countries including Bangladesh, Indonesian, Malaysia and the Middle East countries including Bahrain, Iran, Jordan, Kuwait, Oman, Pakistan, Qatar, Saudi Arabia and Turkey. The purpose of the study is to measure the financial disclosure diversity in these countries, with a view to developing a classification of their similarities and differences in respect to their compliance with International Accounting Standards (IAS). Annual reports of 126 public companies liisted on the countries' stock exchanges are the central data source, supplemented with other relevant information about financial disclosure practices in each country. A disclosure checklist adopted from all IASs and summarised in 306 individual items of financial disclosures is used as a means of extending an understanding of financial reporting in these countries. Results show the relative degree of conformity with IASs for each of the countries included in this study.
