In recent years, the trend of business combinations increased due to the financial and operational reasons. As a result, the financial and operating position of group enterprises (related parties) has become important to provide accurate and reliable information. For this purpose, the consolidated financial statements should be prepared together with the individual financial statements. Consolidation, in the literature, is also known as the consolidated financial statements. Consolidated financial statements are the financial statements of a group presented as a single business. Various institutions have regulations related to the preparation of consolidation. The most important institution is the International Accounting Standards Board (IASB). In this study, we examined the main differences between IFRS 10 “Consolidated Financial Statements” and amended IAS 27 “Consolidated and Individual Financial Statements”, published by the IASB. In addition, we explained consolidation principles and special topics with the help of examples in accordance to IFRS 10.
