Separable components of bundled offers For the sale of multiple products or services (e.g. offers including a handset and a telecommunications service contract), the Group evaluates all promises in the arrangement to determine whether they represent distinct performance obligations i.e. obligations not dependent on each other. Sale of mobile handsets and sale of services in bundled offers are distinct performance obligations. The consideration for the bundled package (i.e. transaction price) is allocated to the distinct performance obligations (e.g. sale of a handset and sale of a service) and recognised as revenue when the performance obligation is satisfied (i.e. when the control over good or service is transferred to a customer). In general, the transaction price is the amount of consideration (usually the cash) to which the Group expects to be entitled during the enforceable period. The enforceable period is the period that is made enforceable through contractual terms or business practices i.e. the enforceable period length is impacted by practices e.g. when the Group creates or accepts a valid expectation to free the customer from certain commitments before the end of the contract by allowing commencement of a new contract. The transaction price does not include the effect of time value of money (except payments by instalments models which, by nature, meet the definition of a financial receivable) because the effect of financing component, in comparison to the transaction price, is not significant at a contract level. The allocation of the transaction price between various performance obligations is made to estimate the amount to which the Group is expected to be entitled in exchange for transferring a promised good or service to the customer. The Group is a service company and achieves the vast majority of its margin by selling telecommunication services. The sale of subsidised handsets (i.e. when an invoice amount for a handset is lower than the cost of a handset) is a tool to promote the Group’s services and to attract customers. Therefore, in case of services sold with subsidised handsets, the Group allocates the subsidy to the service revenues. The Group estimates the amount of revenue that it expects to earn while pricing the service offer. Based on rationale described above, the stand- alone selling price (i.e. the price at which the Group would sell a promised good or service separately to the customer) of subsidised handsets is estimated by their cost plus margin to cover additional costs connected with the sale of handsets, such as e.g. transport costs or logistic costs. The estimated margin is insignificant. Therefore, it is disregarded from the cost plus margin formula for the sake of the practicality. If the Group is able to sell a handset with a profit (i.e. when an invoice amount for a handset is higher than the cost of a handset in bundled offer), it allocates the handset profit to the handset revenue. While defining the stand-alone selling price of any performance obligation, firstly, the Group’s observable price should be identified i.e. the price of good or service when the Group sells that good or service separately in similar circumstances and to similar customers. In case of the lack of an entity observable price, other methods of valuation of an obligation should be used. The stand-alone selling prices of a service are defined per different categories of customers, they are dependent on the service content, commitment period and consumption profile. Therefore, the SIMO price (the price of a service sold stand-alone i.e. not in a bundle with a handset) cannot be treated as a good proxy of the stand-alone selling price of a specific service sold in a bundled offer. Consequently, the stand-alone selling price of the telecommunication service sold in a bundled offer is determined by using an adjusted-market assessment approach and corresponds to the service price in the bundle adjusted by the handset subsidy recovered over the enforceable period. The Group accounts for contract balances if the right to a payment differs from timing when performance obligation is satisfied. A contract asset corresponds to Group’s right to a payment in exchange for goods or services that have been transferred to Group’s customers. A contract asset, if any, is recognised at inception of the contract. It is typically measured as the sum of the monthly subsidy recovery over the remaining enforceable period of the contract. Contract liabilities represent amounts billed to customers by Group before receiving the goods and/or services promised in the contract. This is typically the case for advances received from customers or amounts invoiced for goods or services not yet transferred, such as contracts payable in advance or prepaid packages. Equipment sales Revenue from an equipment sales is recognised when the control over the equipment is transferred to the buyer (see also paragraph “Separable components of bundled offers”). When an equipment is sold by a third-party retailer who purchases it from the Group, the related revenue is recognised when the equipment is sold to the end-customer because the Group acts as a principal in this process. Equipment leases Equipment lease revenue is recognised on a straight-line basis over the life of the lease agreement, except for finance leases, in case of which revenue from sale of fixed assets, equal to the net investment in lease, is recognised at the commencement of the lease and finance income is recognised over the lease term. Revenues from the sale or supply of content Depending on the substance of a transaction and the Group’s role in the transaction, the Group can act as a principal and recognise revenue at the gross amount, separately from costs, or as an agent and recognise revenue in the amount net of costs. The assessment of the role of the Group is based on the notion of the control and the indicators of the control. The Group is treated as a principal if it controls a good or a service before the good or service is transferred to a customer. The Group is considered as an agent if the Group’s performance obligation is to arrange for the provision of a good or a service to the client by another party, i.e. when it does not control the specified good or service provided by another party before that good or service is transferred to the customer. Service revenue Telephone service and Internet access subscription fees are recognised in revenue on a straight-line basis over the service period because of the continuous transfer of control over the service to the customer. Charges for incoming and outgoing telephone calls are recognised in revenue when the service is rendered. Revenue from the sale of phone cards in mobile telephony systems is recognised when they are used or expire. Promotional offers For certain commercial offers where customers do not pay for services over a certain period in exchange for signing up for a fixed period (time-based incentives), the total revenue generated under the contract is spread over the enforceable period. Material rights Material right is an option to purchase additional goods or services with a discount that is incremental to discounts typically given for those goods or services. The Group has not identified any material rights in the contracts with customers which would need to be treated as separate performance obligations.
