On January 1, 2025, the Company adopted 'Lack of Exchangeability (Amendments to IAS 21)' as published by the IASB on August 15, 2023 and that contains guidance to specify when a currency is exchangeable and how to determine the exchange rate when it is not and how an entity determines the exchange rate to apply when a currency is not exchangeable. The amendments also require the disclosure of additional information when a currency is not exchangeable. The adoption of this amendment did not have a material impact on Company's Interim Financial Statements. Use of judgment and estimates The preparation of Interim Financial Statements in conformity with IFRS recognition and measurement principles requires the use of estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. Management reviews its estimates on an ongoing basis using currently available information. Changes in facts and circumstances or obtaining new information or more experience may result in revised estimates, and actual results could differ from those estimates.
