Schedule of interpretations and amendments issued, but not effective

		Mandatory for annual periods
Standards and Interpretations	Description	beginning on or after
Amendment to IAS 1 “Presentation of financial statements” on classification of liabilities.	These amendments clarify that the liabilities will be classified as current or non-current depending on the rights that exist at the close of the reporting period. The classification is not affected by the expectations of the entity or the events subsequent to the report date (for example, the receipt of a waiver or noncompliance with the pact). The amendment also clarifies what IAS 1 means when referring to “liquidation” of a liability. The amendment must be applied retroactively in accordance with IAS 8. Effective date of application January 1, 2022; however, such date was deferred to January 1, 2024.	01-01-2024
Amendment to IAS 1 “Non-current liabilities with covenants”.	The amendment is aimed at improving the information that an entity provides when the payment terms of its liabilities can be deferred depending on compliance with covenants within the twelve months following the date of issue of the financial statements.	01-01-2024
Amendments to IFRS 16 “Leases”	On sales with leaseback, which explains how an entity should recognize the rights to use the asset and how the profits or losses from the sale and leaseback should be recognized in the financial statements.	01-01-2024
Amendments to IAS 1: “Presentation of the Financial Statements” and IAS 8 “Accounting policies, changes in accounting estimates and errors”.	The amendments are intended to improve disclosures of accounting policies and to help users of financial statements distinguish between changes in accounting estimates and changes in accounting policies.	01-01-2023
Amendment to IAS 12 - Deferred taxes related to assets and liabilities that arise from a single transaction.	These amendments require companies to recognize deferred taxes on transactions that result in equal amounts in taxable and deductible temporary differences in the initial recognition.	01-01-2023
Amendment to IFRS 10 “Consolidated Financial Statements” and IAS 28 “Investments in Associates and Joint Ventures”, Published in September 2014.	These amendments address an inconsistency between the requirements in IFRS 10 and those in IAS 28 in dealing with the sale or contribution of assets between an investor and its associate or joint venture. The main consequence of the amendments is that a full gain or loss is recognized when a transaction involves a business -whether it is housed in a subsidiary or not. A partial gain or loss is recognized when a transaction involves assets that do not constitute a business, even if these assets are housed in a subsidiary.	undetermined
