Preparing these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, equity, revenue, expenses, and related disclosures. We evaluate our estimates and assumptions on an ongoing basis. Our estimates are based on historical experience and various other assumptions that we believe to be reasonable under the circumstances. Our actual results may differ from these estimates. The critical accounting estimates, assumptions, and judgments that we believe to have the most significant impact on our consolidated financial statements are described below. Revenue Recognition Premium Revenue We generate revenue for our Premium segment from the sale of Premium Services. Premium Services are sold directly to end users and through partners who are generally telecommunications companies that bundle the subscription with their own services or collect payment for the stand­alone subscriptions from their end customers. Premium Services sold directly to end users are typically paid in advance. We satisfy our performance obligation, and revenue from these services is recognized, on a straight­line basis over the subscription period. We periodically provide discounted trial periods for Premium Services. Consideration received for the discounted trial periods is recognized in revenue on a straight­line basis over the term of the discounted trial period. 80
