The paper examines the revaluation of fixed assets under International Accounting Standard 16 (IAS 16), which addresses "Property, Plant and Equipment" in the financial statements.

It is highlighted that this process can influence the perception of an entity's financial health and strategic decision making. The research focuses on analyzing the impact of fixed asset revaluation under IAS 16 in a sample of 180 companies in Arequipa, Peru.
