This study examines accounting for business combinations under International Accounting Standards, with particular emphasis on IFRS 3 Business Combinations and IAS 36 Impairment of Assets. Using comparative analysis, synthesis of empirical research, and illustrative financial data, the paper evaluates recognition, measurement, and disclosure practices, as well as their implications for transparency and comparability. The findings confirm that standardized accounting treatments improve decision usefulness of financial statements, while challenges remain in fair value measurement and goodwill impairment testing. 2026 2026 05 12 10.54216/JIER.030102 https://www.americaspg.com/articleinfo/42/show/4265
