NOTES TO THE FINANCIAL STATEMENTS 31 DECEMBER 2024 (CURRENCY – SINGAPORE DOLLARS UNLESS OTHERWISE STATED) B2 Revenue (continued) (c) Revenue from contracts (continued) (i) Contracts with enforceable right to payment (continued) Revenue is recognised over time. The stage of completion is typically assessed by reference to either surveys of work performed (output method) or the cost incurred relative to total estimated costs (input method) depending on which method commensurate with the pattern of transfer of control to the customer. (ii) Contracts without enforceable right to payment For contracts where the Group does not have an enforceable right to payment, customers do not take control of the specialised asset until they are completed. At the inception of the contract, the customers usually make an advance payment that is not refundable if the contract is cancelled. The advance payment is presented as a contract liability. The rest of the consideration is only billed upon acceptance by the customer. Revenue is recognised at a point in time when the assets are completed and have been accepted by customers. When the period between the satisfaction of a performance obligation and payment by the customer exceeds a year, the Group adjusts the transaction price with its customer and recognises a financing component. In adjusting for the financing component, the Group uses a discount rate that would be reflected separately as a financing income from contract inception. For contracts with variable consideration (i.e. liquidated damages, bonus and penalty adjustments), revenue is recognised to the extent that it is highly probable that a reversal of previously recognised revenue will not occur. Therefore, the amount of revenue recognised is adjusted for possibility of delays to the projects and ability to meet key performance indicators stipulated in the contract. The Group reviews the progress of the projects at each reporting date and updates the transaction price accordingly. The Group accounts for modifications to the scope or price of a contract as separate contracts if the modification adds distinct goods or services at their stand-alone selling prices. For contract modifications that add distinct goods or services but not at their stand-alone selling prices, the Group combines the remaining consideration in the original contract with the consideration promised in the modification to create a new transaction price that is then allocated to all remaining performance obligations to be satisfied. For contract modifications that do not add distinct goods or services, the Group accounts for the modification as a continuation of the original contract and recognises a cumulative adjustment to revenue at the date of modification. 147 CORPORATE OVERVIEW PERFORMANCE REVIEW SUSTAINABILITY FINANCIAL REPORT
