paragraphs 35-37

BC124 The boards developed the criteria in paragraph 35 of IFRS 15 to provide an objective basis for assessing when control transfers over time and, thus, when a performance obligation is satisfied over time.

Customer simultaneously receives and consumes benefits as entity performs (paragraph 35(a))

BC125 In many typical service contracts, the entity's performance creates an asset only momentarily, because that asset is simultaneously received and consumed by the customer. In those cases, the simultaneous receipt and consumption of the asset that has been created means that the customer obtains control of the entity's output as the entity performs and, thus, the entity's performance obligation is satisfied over time. For example, consider an entity that promises to process transactions on behalf of a customer. The customer simultaneously receives and consumes a benefit as each transaction is processed.
