highly interrelated if each of the promised goods or services is significantly affected by
   one or more of the other goods or services in the contract. As discussed above, the Board
   clarified that an entity would evaluate how two or more promised goods or services affect
   each other and not just evaluate whether one item, by its nature, depends on the other.
   That is, an entity needs to evaluate whether there is a two-way dependency or
   transformative relationship between the promised goods or services to determine
   whether the promises are highly interdependent or highly interrelated.

   In the Basis for Conclusions on IFRS 15, the Board provided the following example. An
   entity promises to design an experimental new product for a customer and to
   manufacture ten prototype units of that product. Because the product and
   manufacturing process is unproven, the entity is required to continue to revise the
   design of the product during the construction and test of the prototypes and make any
   necessary modifications to in-progress or completed prototypes. The entity expects
   that most, or all, of the units to be produced will require some rework because of design
   changes made during the production process. That is, the customer is not likely to be
   able to choose whether to purchase only the design service or the manufacturing service
   without one significantly affecting the other. The entity determines that the design and
   manufacturing promises are highly interdependent on, and highly interrelated with, the
   other promises in the contract. Consequently, although each promise may provide a
   benefit on its own, the promises are not separately identifiable within the context of the
   contract. [IFRS 15.BC112].
   Conversely, if the design was similar to that of a previous product and/or the entity did
   not expect to have to rework the prototypes due to design changes, the entity might
   determine that the two promises are not highly interdependent or highly interrelated
   and might conclude the contract contains multiple performance obligations.
   Goods or services may not be separately identifiable if they are so highly
   interdependent, on or highly interrelated with, other goods or services under the
   contract. This may occur when the customer’s decision not to purchase one promised
   good or service would significantly affect the other promised goods or services. In
   other words, the promised goods or services are so highly interrelated or highly
   interdependent with each other that the entity could not fulfil an individual promise
   independently from the other promises in the contract. This concept regarding an
   entity’s ability to separately fulfil a promise to a customer is highlighted in
   Example 28.22, Case E (see 5.2.3 below). Example 28.22, Case E, includes a contract
   for the sale of equipment and specialised consumables to be used with the
   equipment. In this example, the entity determines that the equipment and
   consumables are not highly interdependent or highly interrelated because the two
   promises do not significantly affect each other. As part of its analysis, the entity
   concludes that it would be able to fulfil each of its promises in the contract
   independently of the other promises.
   (b) March 2018 IFRS Interpretations Committee discussion
   In 2017, the IFRS Interpretations Committee received a request regarding the
   identification of performance obligations in a contract for the sale of a real estate unit
   that includes the transfer of land. The request also asked about the timing of revenue
   recognition for each performance obligation (either over-time or at a point in time),
   which is discussed in 8.1.4.G below. At its March 2018 meeting, the IFRS Interpretations
   Committee concluded that the principles and requirements in IFRS 15 provide sufficient
   guidance for an entity to recognise revenue in a contract for the sale of a real estate unit
   that includes the transfer of land. Consequently, the IFRS Interpretations Committee
   decided not to add this matter to its agenda.35
   2054 Chapter 28
   In considering this request, the IFRS Interpretations Committee noted that the
   assessment of the distinct criteria requires judgement. Furthermore:
   • The assessment of the first criterion is ‘based on the characteristics of the goods or
   services themselves. Accordingly, an entity disregards any contractual limitations
   that might preclude the customer from obtaining readily available resources from
   a source other than the entity’ (see 5.2.1.A above). [IFRS 15.BC100].
   • The objective underlying the second criterion is to determine the nature of the
   promise within the context of the contract. That is, whether the entity has
   promised to transfer either the promised goods or services individually or a
   combined item to which those goods or services are inputs. IFRS 15 also includes
   some factors that indicate that two or more promises to transfer goods or services
   are not separately identifiable. [IFRS 15.29]. However, these factors are not intended
   to be criteria that an entity evaluates independently of the ‘separately identifiable’
   principle because, in some instances, one or more of the factors may be less
   relevant to the evaluation of that principle (see the discussion above).
   [IFRS 15.BC116N].
   In the Basis for Conclusion, the Board indicated that the separately identifiable
   concept is influenced by the idea of separable risks. That is, whether the risk
   assumed to fulfil the obligation to transfer one of the promised goods or services
   to the customer is separable from the risk relating to the transfer of the other
   promised goods or services. Evaluating whether an entity’s promise is separately
   identifiable considers the interrelationship between the goods or services within
   the contract in the context of the process to fulfil the contract. Accordingly, an
   entity considers the level of integration, interrelation or interdependence among
   the promises in the contract to transfer goods or services. An entity evaluates
   whether, in the process of fulfilling the contract, there is a transformative
   relationship between the promises, rather than considering whether one item, by
   its nature, depends on another (i.e. whether the promises have a functional
   relationship). [IFRS 15.BC105, 116J, 116K].
   The IFRS Interpretations Committee discussed the identification of performance
   obligations in its March 2018 meeting using the following example from the IFRS
   Interpretations Committee agenda paper:36
   Example 28.16: Identification of performance obligations in a contract for the sale
   of a real estate unit that includes the transfer of land
   Entity A enters into a non-cancellable contract with a customer for the sale of a real estate unit that involves
   the transfer of a plot of land and a building that Entity A constructs on that land. The land represents all of
   the area on which the building will be constructed and the contract is for the entire building.
   At contract inception, Entity A transfers the legal title of the land and the customer pays the price specified
   in the contract for it. The transfer of legal title to the customer cannot be revoked, regardless of what happens
   during the construction of the building. Throughout the c
onstruction period, the customer makes milestone
   payments that do not necessarily correspond to the amount of work completed to date.
   The design and specification of the building were agreed between the counterparties before the contract
   was signed. However, during the construction of the building, the customer can request changes to the
   design and specification that are priced by Entity A based on a methodology specified in the contract. If
   the customer decides to proceed with the proposed changes, Entity A can reject them only for a limited
   Revenue
   2055
   number of reasons (e.g. when the change would breach planning permission). Entity A can only request
   changes if not doing so would lead to an unreasonable increase in costs or delay construction. However,
   the customer must approve those changes.
   Entity A first assesses whether the land and the building are each capable of being distinct in accordance with
   paragraph 27(a) of IFRS 15. Entity A determines that the customer could benefit from the land on its own or
   together with other resources readily available to it e.g. by hiring another developer to construct a building
   on the land. Also, Entity A determines that the customer could benefit from the construction of the building
   on its own or together with other resources readily available to it. For example, by obtaining the construction
   services from Entity A or another developer without transferring the land. Therefore, Entity A concludes that
   the land and the building are each capable of being distinct.
   The criterion in paragraph 27(b) of IFRS 15 is then assessed by Entity A in order to determine whether the
   land and the building are distinct in the context of the contract. In making this assessment, Entity A considers
   the factors in paragraph 29 of IFRS 15, including the following:
   a.
   Whether it provides a significant service of integrating the land and the building into a combined output.
   Entity A analyses the transformative relationship between the transfer of the land and the construction
   of the building in the process of fulfilling the contract. In making this analysis it considers whether its
   performance in constructing the building would be different if it did not also transfer the land and vice
   versa. Despite the functional relationship between the land and the building (because the building cannot
   exist without the land on which its foundations will be built), the risks assumed by Entity A in
   transferring the land may, or may not, be separable from those assumed in constructing the building.
   b. Whether the land and the building are highly interdependent or highly interrelated. Entity A determines
   whether its promise to transfer the land could be fulfilled if it did not also construct the building and vice versa.
   The IFRS Interpretations Committee concluded that the two promises would be separately identifiable if
   Entity A concluded that ‘(a) its performance in constructing the building would be the same regardless of
   whether it also transferred the land; and (b) it would be able to fulfil its promise to construct the building even
   if it did not also transfer the land, and would be able to fulfil its promise to transfer the land even if it did not
   also construct the building.’37
   (c) Examples
   The IASB included a number of examples in the standard that illustrate the application
   of the requirements for identifying performance obligations. The examples include
   analysis of how an entity may determine whether the promises to transfer goods or
   services are distinct within the context of the contract. See 5.2.3 below for full extracts
   of several of these examples.
   IAS 18 indicated that an entity may need to apply its recognition criteria to separately
   identifiable elements in order to reflect the substance of the transaction. However, it
   did not provide additional application guidance for determining those separate
   elements. As such, the requirements in IFRS 15 may change practice.
   Many IFRS preparers developed their legacy IFRS accounting policies by reference to
   legacy US GAAP. Whether the new standard results in a change in practice may depend
   on which US GAAP requirements they had considered when developing their policies.
   The first step of the two-step process to determine whether goods or services are distinct
   is similar to the principles for determining separate units of accounting under legacy
   US GAAP requirements in ASC 605-25 – Revenue Recognition – Multiple-Element
   Arrangements. However, the second step of considering the goods or services within the
   context of the contract is a new requirement that entities have found especially
   challenging to apply. Therefore, entities need to carefully evaluate this second step to
   2056 Chapter 28
   determine whether their historical units of account for revenue recognition may need to
   change. This evaluation may require an entity to use significant judgement.
   Entities that had previously looked to other legacy US GAAP requirements to develop
   their accounting policies, such as ASC 985-605 – Software – Revenue Recognition,
   may also reach different conclusions under IFRS 15.
   It is important to note that the assessment of whether a good or service is distinct must
   consider the specific contract with a customer. That is, an entity cannot assume that a
   particular good or service is distinct (or not distinct) in all instances. The manner in which
   promised goods or services are bundled within a contract can affect the conclusion of
   whether a good or service is distinct. We anticipate that entities may treat the same goods or
   services differently, depending on how those goods or services are bundled within a contract.
   5.2.2
   Series of distinct goods or services that are substantially the same
   and have the same pattern of transfer
   As discussed above, paragraph 22(b) of IFRS 15 defines, as a second type of performance
   obligation, a promise to transfer to the customer a series of distinct goods or services
   that are substantially the same and that have the same pattern of transfer, if both of the
   following criteria from paragraph 23 of IFRS 15 are met: [IFRS 15.22(b), 23]
   • each distinct good or service in the series that the entity promises to transfer
   represents a performance obligation that would be satisfied over time in
   accordance with paragraph 35 of IFRS 15 (see 5.2.2.A and 8.1 below), if it were
   accounted for separately; and
   • the entity would measure its progress toward satisfaction of the performance
   obligation using the same measure of progress for each distinct good or service in
   the series (see 8.2 below).

   If a series of distinct goods or services meets the criteria in paragraph 22(b) of IFRS 15
   and paragraph 23 of IFRS 15 (i.e. the series requirement), an entity is required to treat
   that series as a single performance obligation (i.e. it is not optional). The Board
   incorporated this requirement to simplify the model and promote consistent
<
br />   identification of performance obligations in cases when an entity provides the same
   good or service over a period of time. [IFRS 15.BC113]. Without the series requirement,
   the Board noted that applying the revenue model might present operational
   challenges because an entity would have to identify multiple distinct goods or
   services, allocate the transaction price to each distinct good or service on a stand-
   alone selling price basis and then recognise revenue when those performance
   obligations are satisfied. The IASB determined that this would not be cost effective.
   Instead, an entity identifies a single performance obligation and allocates the
   Revenue
   2057
   transaction price to that performance obligation. It will then recognise revenue by
   applying a single measure of progress to that performance obligation. [IFRS 15.BC114].
   For distinct goods or services to be accounted for as a series, one of the criteria is that they
   must be substantially the same. This is often the most difficult criterion for entities to assess.
   In the Basis for Conclusions, the Board provided three examples of repetitive services
   (i.e. cleaning, transaction processing and delivering electricity) that meet the series
   requirement. [IFRS 15.BC114]. In addition, the TRG members generally agreed that when
   determining whether distinct goods or services are substantially the same, entities need to
   first determine the nature of their promise. This is because a series could consist of either
   specified quantities of the underlying good or service delivered (e.g. each unit of a good) or
   distinct time increments (e.g. an hourly service), depending on the nature of the promise.
   That is, if the nature of the promise is to deliver a specified quantity of service (e.g. monthly
   payroll services over a defined contract period), the evaluation considers whether each
   service is distinct and substantially the same. In contrast, if the nature of the entity’s promise
   is to stand ready or provide a single service for a period of time (i.e. because there is an
   unspecified quantity to be delivered), the evaluation considers whether each time increment
   (e.g. hour, day), rather than the underlying activities, is distinct and substantially the same.38
   Figure 28.9 illustrates how the determination of the nature of the promise might affect
