Customers are billed for the services to which they subscribe based upon published or contracted rates, with the sales price being allocated to each performance obligation. For arrangements with multiple performance obligations, the sales price is allocated based on the relative standalone selling price for each subscribed service. Generally performance obligations are satisfied, and revenue is recognized, over the period of time in which customers simultaneously receive and consume the Company’s defined performance obligations, which are delivered in a similar pattern of transfer. Advertising revenue is recognized at the point in time when the underlying performance obligation is complete.
