This study investigates the level of convergence of accounting practices in industrial companies in the MERCOSUR and Andean Community countries. Starting from a theoretical basis which identified the current stage of adoption of International Accounting Standards in the countries of these two economic blocs, it was possible to compare regulatory convergence with accounting practice. To this end, the measurement and disclosure of the main equity elements in a sample of thirty industrial companies in the countries of these two South American economic blocs was analyzed.
