Contract assets relate to the portion of performance obligations fulfilled by the Group for which the definitive right to be paid is subject to the completion of works specified in the relevant contracts. Contract assets turn into receivables as these works are accepted by the client, giving rise to the Group’s unconditional right to be paid.
