(1) We record deferred revenues when cash payments are received or due in advance of our performance. For the years ended December 31, 2017 and 2018, the Company recognized revenue of 10,751,000 and $11,813,000, respectively, that was included in the deferred revenue balance at the beginning of each reporting period. The Company expects to recognize as revenue before year 2023, when it transfers those goods and services and, therefore, satisfies its performance obligation to the customers. We do not separately account for activation fees since no good or service is transferred to the customer. Therefore, the activation fee is included in the transaction price and allocated to the performance obligations in the contract and deferred/amortized over the life of the contract.
