Notes to the Consolidated Financial Statements
The performance obligation is satisfied and revenue is recorded at the point in time that the transportation services are complete and billed monthly based on the right to invoice practical expedient, with collection generally occurring in the following month. Interruptible transportation service contracts Transportation service is not provided on a guaranteed basis. The Corporation can generally interrupt service performance with short or no notice. The Corporation may curtail an interruptible customer’s service if the service is required to serve a higher priority customer. Curtailment of interruptible service may occur to protect the operational integrity of the natural gas system and ensure delivery to their firm transportation contract holders. Curtailment generally will restrict service to customers that have interruptible transportation contracts. Interruptible customers will be curtailed in order of priority to ensure firm deliveries are met first. Interruptible service usually costs less than firm service as interruptible service is less reliable. The entire interruptible service contract is variable based on customer flow of an unknown quantity of natural gas contracted at a predetermined rate. Transaction prices published in the Corporation’s tariff are allocated to the performance obligation based on the measured volumes transported by the customer. Interruptible services may have a term as short as one month. Interruptible transportation services are recognized as revenue at the point in time that the Corporation completes the transportation services to the customer. These services are generally invoiced in the month after the services are performed, as this is when the service performance obligation is complete. There are no significant financing components, nor any non-cash consideration. Storage service The contracts for storage services provide customers with operational flexibility to store natural gas during periods of low demand to ensure that sufficient supply is available during periods of high demand. Storage services are contracted independently of transportation services and are considered one performance obligation recognized over time. The Corporation’s tariff, as well as associated Service Agreements and Schedules of Service, are applicable to each customer and their services requested. The customer receives the benefit of storage services and the Corporation has the right to invoice the customer for the services provided. Customers are invoiced in the month following the receipt of service, payable within 15 days of invoicing. The transaction prices published in the Corporation’s tariff are allocated to the single performance obligation based on the volumes contracted with the customer. Revenues are recognized at the point in time that the Corporation completes the storage service to the customer. There are no significant financing components, nor any non-cash consideration. iv. Unbilled revenue Unbilled revenue is estimated monthly for services provided but not yet billed using management’s judgments and assumptions. v. Customer contributions The Corporation builds customer-requested distribution and transmission facilities and the title, risks and rewards of these facilities remain with the Corporation at all times during and after construction, as permitted by The SaskEnergy Act .
