Contract liabilities represent an entity’s obligation to transfer goods or services to a customer for which the entity has received consideration, or the amount that is due, from the customer. At June 30, 2018 and December 31, 2017, Questar Gas’ contract liability balances were $11.4 million and $17.3 million, respectively. During the six months ended June 30, 2018, Questar Gas recognized revenue of $17.3 million from the beginning contract liability balance as Questar Gas fulfilled its obligations to provide service to its customers.
