2. Revenue Recognition

Revenues consist primarily of subscription fees paid by our customers. We present revenues net of taxes collected from customers. Subscribers are billed in advance and revenues are recognized ratably over the subscription term. Deferred revenues consist of subscription fees collected from customers that have not been earned and are recognized ratably over the remaining term of the subscription. We recognize revenue on a net basis for relationships where our partners have the primary relationship, including billing and service delivery, with the subscriber. Payments made to partners to assist in promoting our service on their platforms are expensed as marketing expenses in the period incurred. We do not allow access to our service to be provided as part of a bundle by any of our partners.
