         COMMISSION DELEGATED REGULATION (EU) 2019/2100
         of 30 September 2019
         amending Delegated Regulation (EU) 2019/815 with regard to updates of the taxonomy to be used 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 (‘IFRS’), adopted pursuant to Regulation (EC) No 1606/2002 of the European Parliament and of the Council (3), or in accordance with IFRS as issued by the International Accounting Standards Board (IASB) which are considered as equivalent to IFRS adopted pursuant to Regulation (EC) No 1606/2002 based on Commission Decision 2008/961/EC (4).
                  
               
                     (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 or the amendment of existing IFRS, the analysis of disclosures commonly reported in practice, or improvements to the IFRS Taxonomy's general content or technology. Therefore, it is necessary to update the regulatory technical standards in order to reflect the relevant changes in the IFRS Taxonomy.
                  
               
                     (3)
                  
                  
                     Delegated Regulation (EU) 2019/815 should therefore be amended accordingly.
                  
               
                     (4)
                  
                  
                     This Regulation is based on the draft regulatory technical standard submitted by the European Securities and Markets Authority to the Commission,
                  
               HAS ADOPTED THIS REGULATION:

                        This member stands for all actuarial assumptions. Actuarial assumptions are the entity’s unbiased and mutually compatible best estimates of the demographic and financial variables that will determine the ultimate cost of providing post-employment benefits. It also represents the standard value for the ‘Actuarial assumptions’ axis if no other member is used.

Demographic assumptions deal with matters such as: (a) mortality; (b) rates of employee turnover, disability and early retirement; (c) the proportion of plan members with dependants who will be eligible for benefits; (d) the proportion of plan members who will select each form of payment option available under the plan terms; and (e) claim rates under medical plans.

Financial assumptions deal with items such as: (a) the discount rate; (b) benefit levels, excluding any cost of the benefits to be met by employees, and future salary; (c) in the case of medical benefits, future medical costs, including claim handling costs (ie the costs that will be incurred in processing and resolving claims, including legal and adjuster's fees); and (d) taxes payable by the plan on contributions relating to service before the reporting date or on benefits resulting from that service.

                        This member stands for a class of intangible assets arising from development expenditure capitalised before the start of commercial production or use. An intangible asset shall only be recognised if the entity can demonstrate all of the following: (a) the technical feasibility of completing the intangible asset so that it will be available for use or sale; (b) its intention to complete the intangible asset and use or sell it; (c) its ability to use or sell the intangible asset; (d) how the intangible asset will generate probable future economic benefits. Among other things, the entity can demonstrate the existence of a market for the output of the intangible asset or the intangible asset itself or, if it is to be used internally, the usefulness of the intangible asset; (e) the availability of adequate technical, financial and other resources to complete the development and to use or sell the intangible asset; and (f) its ability to measure reliably the expenditure attributable to the intangible asset during its development.

Defined contribution plans are post-employment benefit plans under which an entity pays fixed contributions into a separate entity (a fund) and will have no legal or constructive obligation to pay further contributions if the fund does not hold sufficient assets to pay all employee benefits relating to employee service in the current and prior periods. It also represents the standard value for the ‘Defined benefit plans’ axis if no other member is used.

                        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.

A component of an entity comprises operations and cash flows that can be clearly distinguished, operationally and for financial reporting purposes, from the rest of the entity.

                        This member stands for a specific valuation technique consistent with the income approach that involves analysing future cash flow amounts through the application of present value techniques and inputs (for example, weighted average cost of capital, long-term revenue growth rate, long-term pre-tax operating margin, discount for lack of marketability, control premium).

                        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.

                        The amount of expense relating to restructuring. 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 amount of the expense relating to leases of low-value assets accounted for applying paragraph 6 of IFRS 16. This expense shall not include the expense relating to short-term leases of low-value assets.

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.

                        The amount of financial liabilities at amortised cost. The amortised cost is the amount at which financial liabilities are measured at initial recognition minus principal repayments, plus or minus the cumulative amortisation using the effective interest method of any difference between that initial amount and the maturity amount.

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.

                        The increase (decrease) in deferred acquisition costs arising from insurance contracts that result from shadow accounting. Shadow accounting is a practice with the following two features: (a) a recognised but unrealised gain or loss on an asset affects the measurement of the insurance liability in the same way that a realised gain or loss does; and (b) if unrealised gains or losses on an asset are recognised directly in equity, the resulting change in the carrying amount of the insurance liability is also recognised in equity.

                        This member stands for contracts under which one party (the issuer) accepts significant insurance risk from another party (the policyholder) by agreeing to compensate the policyholder if a specified uncertain future event (the insured event) adversely affects the policyholder. All references in IFRS 17 to insurance contracts also apply to: (a) reinsurance contracts held, except: (i) for references to insurance contracts issued; and (ii) as described in paragraphs 60–70 of IFRS 17; (b) investment contracts with discretionary participation features provided the entity also issues insurance contracts, except for the reference to insurance contracts in paragraph 3(c) of IFRS 17 and as described in paragraph 71 of IFRS 17. 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. This member also represents the standard value for the ‘Insurance contracts’ axis if no other member is used.

                        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).

                        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 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.

                        This member stands for operating segments for which IFRS 8 requires information to be disclosed. The entity shall report separately information about an operating segment that meets any of the following quantitative thresholds: (a) reported revenue, including both sales to external customers and intersegment sales or transfers, is 10 per cent or more of the combined revenue, internal and external, of all operating segments; (b) the absolute amount of its reported profit or loss is 10 per cent or more of the greater, in absolute amount, of (i) the combined reported profit of all operating segments that did not report a loss and (ii) the combined reported loss of all operating segments that reported a loss; or (c) assets are 10 per cent or more of the combined assets of all operating segments. 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.

                        The yield used to discount cash flows that do not vary based on the returns on underlying items, applying paragraph 36 of IFRS 17. Underlying items are items that determine some of the amounts payable to a policyholder. Underlying items can comprise any items; for example a reference portfolio of assets, the net assets of the entity, or a specified subset of the net assets of the entity.
