CTFA Annual Report 2022

12. Revenue 12.1 Accounting policies Revenue is measured at the fair value of the consideration received or receivable. Revenue is shown net of value-added tax, returns, rebates and discounts. When the outcome of a transaction involving the rendering of services can be estimated reliably, revenue associated with the transaction is recognised by reference to the stage of completion of the transaction at the end of the reporting period. The outcome of a transaction can be estimated reliably when all the following conditions are satisfied: • the amount of revenue can be measured reliably; • it is probable that the economic benefits associated with the transaction will flow to the entity; • the stage of completion of the transaction at the end of the reporting period can be measured reliably; and • the costs incurred for the transaction and the costs to complete the transaction can be measured reliably. When the outcome of transactions involving the rendering of services cannot be estimated reliably, revenue is recognised only to the extent of the expenses recognised that are recoverable. The stage of completion of a transaction may be determined by a variety of methods, depending on the nature of the transaction: • surveys of work performed; • services performed to date as a percentage of total services to be performed; • the proportion that costs incurred to date bear to the estimated total costs of the transaction. Only costs that reflect services performed to date are included in costs incurred to date. Only costs that reflect services performed or to be performed are included in the estimated total costs of the transaction. Interest income is recognised using the effective interest method. 12.2 Revenue comprises Membership fees 5,972,101 5,694,726 13.
