         COMMISSION DELEGATED REGULATION (EU) 2020/1989
         of 6 November 2020
         amending Delegated Regulation (EU) 2019/815 as regards the 2020 update of the taxonomy laid down in the regulatory technical standards for the single electronic reporting format
         (Text with EEA relevance)
         THE EUROPEAN COMMISSION,
         Having regard to the Treaty on the Functioning of the European Union,
         Having regard to Directive 2004/109/EC of the European Parliament and of the Council of 15 December 2004 on the harmonisation of transparency requirements in relation to information about issuers whose securities are admitted to trading on a regulated market and amending Directive 2001/34/EC (1), and in particular Article 4(7) thereof,
         Whereas:
         
                     (1)
                  
                  
                     Commission Delegated Regulation (EU) 2019/815 (2) specifies the single electronic reporting format, as referred to in Article 4(7) of Directive 2004/109/EC, to be used for the preparation of annual financial reports by issuers. Consolidated financial statements included therein are prepared either in accordance with International Accounting Standards, which are commonly referred to as International Financial Reporting Standards (‘IFRSs’), adopted pursuant to Regulation (EC) No 1606/2002 of the European Parliament and of the Council (3), or in accordance with IFRSs as issued by the International Accounting Standards Board (IASB) which, based on Commission Decision 2008/961/EC (4), are considered as equivalent to IFRSs adopted pursuant to Regulation (EC) No 1606/2002.
                  
               
                     (2)
                  
                  
                     The core taxonomy to be used for the single electronic reporting format is based on the IFRS Taxonomy and is an extension of it. The IFRS Foundation annually updates the IFRS Taxonomy to reflect, amongst other developments, the issuance of new IFRSs or the amendment of existing IFRSs, the analysis of disclosures commonly reported in practice, or improvements to general content or technology of the IFRS Taxonomy. Therefore, it is necessary to update the regulatory technical standards to reflect each annual update of the IFRS Taxonomy.
                  
               
                     (3)
                  
                  
                     In March 2020 the IFRS Foundation published the updated version of the IFRS Taxonomy. That update should therefore be reflected in Delegated Regulation (EU) 2019/815.
                  
               
                     (4)
                  
                  
                     In order to allow enough time for the effective implementation of the requirements by issuers, and to minimise compliance costs, this Regulation should apply to annual financial reports containing financial statements for financial years beginning on or after 1 January 2021. However, issuers should be allowed to adopt the taxonomy specified in this Regulation already for financial years beginning on or after 1 January 2020.
                  
               
                     (5)
                  
                  
                     The copyright, the database rights and any other intellectual property rights in the IFRS Taxonomy are owned by the IFRS Foundation. A copyright notice should therefore be included in Annex I to Delegated Regulation (EU) 2019/815.
                  
               
                     (6)
                  
                  
                     Delegated Regulation (EU) 2019/815 should therefore be amended accordingly.
                  
               
                     (7)
                  
                  
                     This Regulation is based on the draft regulatory technical standard submitted to the Commission by the European Securities and Markets Authority.
                  
               
                     (8)
                  
                  
                     This Regulation is a technical update to Delegated Regulation (EU) 2019/815 to reflect updates in the IFRS taxonomy and as such does not constitute new policy or a substantial change to existing policy. ESMA has not conducted open public consultations on the draft regulatory technical standards on which this Regulation is based, analysed the potential related costs and benefits or requested the advice of the Securities and Markets Stakeholder Group established under Article 37 of Regulation (EU) No 1095/2010 of the European Parliament and of the Council (5) because doing so would have been highly disproportionate to the scope and impact of this amendment,
                  
               HAS ADOPTED THIS REGULATION:
         
            Article 1
            Amendments to Delegated Regulation (EU) 2019/815
            Delegated Regulation (EU) 2019/815 is amended as follows:

                        Annex I is amended in accordance with Annex I to this Regulation;
                     
                  
                        (2)

            Article 2
            Transitional provision
            By way of derogation from Delegated Regulation (EU) 2019/815 as amended by Commission Delegated Regulation (EU) 2019/2100 (6), this Regulation may be applied to annual financial reports containing financial statements for financial years beginning before 1 January 2021.
         
         
            Article 3
            Entry into force and application
            This Regulation shall enter into force on the twentieth day following that of its publication in the Official Journal of the European Union.
            It shall apply from 1 January 2021 to annual financial reports containing financial statements for financial years beginning on or after 1 January 2021.
            However, Article 2 shall apply from the date of entry into force of this Regulation.
         
         
            This Regulation shall be binding in its entirety and directly applicable in all Member States.
            Done at Brussels, 6 November 2020.

                                 The description of the composition of the underlying items for contracts with direct participation features. Insurance contracts with direct participation features are insurance contracts for which, at inception: (a) the contractual terms specify that the policyholder participates in a share of a clearly identified pool of underlying items; (b) the entity expects to pay to the policyholder an amount equal to a substantial share of the fair value returns on the underlying items; and (c) the entity expects a substantial proportion of any change in the amounts to be paid to the policyholder to vary with the change in fair value of the underlying items. Underlying items are items that determine some of the amounts payable to a policyholder.

                                 The amount of the discounted unguaranteed residual value of assets subject to finance leases. Unguaranteed residual value is the portion of the residual value of the underlying asset, the realisation of which by a lessor is not assured or is guaranteed solely by a party related to the lessor. Finance lease is a lease that transfers substantially all the risks and rewards incidental to ownership of an underlying asset.

Restructuring is a programme that is planned and controlled by management and materially changes either the scope of a business undertaken by an entity or the manner in which that business is conducted. Such programmes include: (a) the sale or termination of a line of business; (b) closure of business locations in a country or region or the relocation of activities from one country or region to another; (c) changes in management structure; and (d) fundamental reorganisations that have a material effect on the nature and focus of the entity’s operations.

The incremental borrowing rate is the rate of interest that a lessee would have to pay to borrow over a similar term, and with a similar security, the funds necessary to obtain an asset of a similar value to the right-of-use asset in a similar economic environment.

For this purpose, rights, options or warrants to acquire a fixed number of the entity’s own equity instruments for a fixed amount of any currency are equity instruments if the entity offers the rights, options or warrants pro rata to all of its existing owners of the same class of its own non-derivative equity instruments. Also, for those purposes the entity’s own equity instruments do not include puttable financial instruments that are classified as equity instruments in accordance with paragraphs 16A-16B of IAS 32, instruments that impose on the entity an obligation to deliver to another party a pro rata share of the net assets of the entity only on liquidation and are classified as equity instruments in accordance with paragraphs 16C-16D of IAS 32, or instruments that are contracts for the future receipt or delivery of the entity’s own equity instruments. As an exception, an instrument that meets the definition of a financial liability is classified as an equity instrument if it has all the features and meets the conditions in paragraphs 16A-16B or paragraphs 16C-16D of IAS 32.

An entity may use this designation only when permitted by paragraph 4.3.5 of IFRS 9 (embedded derivatives) or when doing so results in more relevant information, because either: (a) it eliminates or significantly reduces a measurement or recognition inconsistency (sometimes referred to as “an accounting mismatch”) that would otherwise arise from measuring assets or liabilities or recognising the gains and losses on them on different bases; or (b) a group of financial liabilities or financial assets and financial liabilities is managed and its performance is evaluated on a fair value basis, in accordance with a documented risk management or investment strategy, and information about the group is provided internally on that basis to the entity’s key management personnel (as defined in IAS 24).

                                 This member stands for hedging instruments. A hedging instrument can be a designated: (a) derivative measured at fair value through profit or loss, except for some written options (see paragraph B6.2.4 of IFRS 9); (b) non-derivative financial asset or non-derivative financial liability measured at fair value through profit or loss, unless it is a financial liability designated as at fair value through profit or loss for which the amount of its change in fair value that is attributable to changes in the credit risk of that liability is presented in other comprehensive income in accordance with paragraph 5.7.7 of IFRS 9. For a hedge of foreign currency risk, the foreign currency risk component of a non-derivative financial asset or a non-derivative financial liability may be designated as a hedging instrument provided that it is not an investment in an equity instrument for which an entity has elected to present changes in fair value in other comprehensive income in accordance with paragraph 5.7.5 of IFRS 9. This member also represents the standard value for the “Hedging instruments” axis if no other member is used.

                                 The amount of non-derivative financial assets with fixed or determinable payments and fixed maturity that an entity has the positive intention and ability to hold to maturity other than: (a) those that the entity upon initial recognition designates as at fair value through profit or loss; (b) those that the entity designates as available for sale; and (c) those that meet the definition of loans and receivables. An entity shall not classify any financial assets as held to maturity if the entity has, during the current financial year or during the two preceding financial years, sold or reclassified more than an insignificant amount of held-to-maturity investments before maturity (more than insignificant in relation to the total amount of held-to-maturity investments) other than sales or reclassifications that: (i) are so close to maturity or the financial asset’s call date (for example, less than three months before maturity) that changes in the market rate of interest would not have a significant effect on the financial asset’s fair value; (ii) occur after the entity has collected substantially all of the financial asset’s original principal through scheduled payments or prepayments; or (iii) are attributable to an isolated event that is beyond the entity’s control, is non-recurring and could not have been reasonably anticipated by the entity.

An investment contract with discretionary participation features is a financial instrument that provides a particular investor with the contractual right to receive, as a supplement to an amount not subject to the discretion of the issuer, additional amounts: (a) that are expected to be a significant portion of the total contractual benefits; (b) the timing or amount of which are contractually at the discretion of the issuer; and (c) that are contractually based on: (i) the returns on a specified pool of contracts or a specified type of contract; (ii) realised and/or unrealised investment returns on a specified pool of assets held by the issuer; or (iii) the profit or loss of the entity or fund that issues the contract.

                                 The intrinsic value of liabilities arising from share-based transactions for which the counterparty’s right to cash or other assets had vested by the end of the period (for example, vested share appreciation rights). The intrinsic value is the difference between the fair value of the shares to which the counterparty has the (conditional or unconditional) right to subscribe, or which it has the right to receive, and the price (if any) that the counterparty is (or will be) required to pay for those shares. Share-based payment transactions are transactions in which the entity: (a) receives goods or services from the supplier of those goods or services (including an employee) in a share-based payment arrangement; or (b) incurs an obligation to settle the transaction with the supplier in a share-based payment arrangement when another group entity receives those goods or services, for which the counterparty’s right to cash or other assets had vested by the end of the period (for example, vested share appreciation rights).

                                 This member stands for a category of the fair value hierarchy where inputs to the valuation techniques are unobservable inputs for the asset or liability. Unobservable inputs are inputs for which market data are not available and that are developed using the best information available about the assumptions that the market participants would use when pricing the asset or liability.

An entity shall establish (or increase) a loss component of the liability for remaining coverage for an onerous group depicting the losses recognised applying paragraphs 47–48 of IFRS 17. The loss component determines the amounts that are presented in profit or loss as reversals of losses on onerous groups and are consequently excluded from the determination of insurance revenue.

                                 The gross investment in the finance lease discounted at the interest rate implicit in the lease. Finance lease is a lease that transfers substantially all the risks and rewards incidental to ownership of an underlying asset. Gross investment in the finance lease is the sum of: (a) the lease payments receivable by a lessor under a finance lease; and (b) any unguaranteed residual value accruing to the lessor. Interest rate implicit in the lease is the rate of interest that causes the present value of (a) the lease payments and (b) the unguaranteed residual value to equal to the sum of (i) the fair value of the underlying asset and (ii) the initial direct costs of the lessor.

                                 This member stands for all performance obligations. A performance obligation is a promise in a contract with a customer to transfer to the customer either: (a) a good or service (or a bundle of goods or services) that is distinct; or (b) a series of distinct goods or services that are substantially the same and that have the same pattern of transfer to the customer. This member also represents the standard value for the “Performance obligations” axis if no other member is used.

                                 This member stands for performance obligations satisfied over time. An entity satisfies a performance obligation over time, if one of the following criteria is met: (a) the customer simultaneously receives and consumes the benefits provided by the entity’s performance as the entity performs; (b) the entity’s performance creates or enhances an asset (for example, work in progress) that the customer controls as the asset is created or enhanced; or (c) the entity’s performance does not create an asset with an alternative use to the entity and the entity has an enforceable right to payment for performance completed to date.

                                 This member stands for regulatory deferral account balances. A regulatory deferral account balance is the balance of any expense (or income) account that would not be recognised as an asset or a liability in accordance with other Standards, but that qualifies for deferral because it is included, or is expected to be included, by the rate regulator in establishing the rate(s) that can be charged to customers. This member also represents the standard value for the “Regulatory deferral account balances” axis if no other member is used.

Additionally operating segments that do not meet any of the quantitative thresholds may be considered reportable, and separately disclosed, if management believes that information about the segment would be useful to users of the financial statements.

                                 This member stands for arrangements in which an entity (the operator) may enter into an arrangement with another entity (the grantor) to provide services that give the public access to major economic and social facilities. The grantor may be a public or private sector entity, including a governmental body. Examples of service concession arrangements involve water treatment and supply facilities, motorways, car parks, tunnels, bridges, airports and telecommunication networks. Examples of arrangements that are not service concession arrangements include an entity outsourcing the operation of its internal services (for example, employee cafeteria, building maintenance, and accounting or information technology functions). It also represents the standard value for the “Service concession arrangements” axis if no other member is used.
