(i)Deferred revenue
Deferred revenue relates primarily to cash contributions from third parties for future natural gas and electricity connections at our U.K. regulated distribution operation, advance customer payments for container leases at our global intermodal logistics operation, to build or upgrade existing network capabilities at our Australian rail operation, for future servicing of customer contracts and protection plans at our North American and European residential decarbonization infrastructure operation and to build or upgrade existing networks at our U.K. wireless infrastructure operation. The deferred revenue is recorded on receipt of cash payments and recognized as revenue as services are rendered over the life of the connections arrangements, container lease agreements, contracted track access, contract plans or networks.
