Historically, BCE charged maintenance and other on-site services as customers requested the service. These charges typically varied between $150 for one hour of service time and $1,000 for a full day's service time. The time spent at a customer's location depended on the customer's service needs. BCE's average expenses related to these service calls were $75 per hour. In October 2023, in response to existing customers requesting a fixed-price service contract, BCE offered a new product - Service Contracts. If a customer purchased the Service Contracts, they would receive, at no additional charge, unlimited service visits from BCE. Customers must pay a nonrefundable $600 Service Contract fee before December 31, 2023, to enroll in the new program. The Service Contracts are on a calendar year basis beginning January 1, 2024, and expiring December 31, 2024. BCE sold $22,100 of the service contracts during October- December 2023 and recorded it as service revenue when collected. What entry, if any, is necessary in this circumstance? What disclosure, if any, should BCE make related to these service contracts
