Sirius XM Radio (SIRI)

We recognize subscription fees as our service is provided to a subscriber. We record deferred revenue for prepaid subscription fees and amortize these prepayments to revenue ratably over the term of the respective subscription plan. At the time of sale, vehicle owners purchasing or leasing a vehicle with a subscription typically receive between a six-month and one-year prepaid subscription. We receive payment from automakers for these subscriptions in advance of our service being activated. We also reimburse the automakers for certain costs associated with the SIRIUS radio installed in the applicable vehicle at the time the vehicle is manufactured. The associated payments to the automakers are included in subscriber acquisition costs. Although we receive payments from the automakers, we believe that they do not resell our service; rather, they facilitate the sale of our service to our customers similar to an agent. We believe this is the appropriate characterization of our relationship since we are responsible for providing services to our customers including being obligated to the customer if there were interruption of service.

Activation fees are recognized ratably over the estimated term of a subscriber relationship, currently estimated to be 3.5 years. The estimated term of a subscriber relationship is based on market research and management’s judgment and, if necessary, will be refined in the future as historical data becomes available.

As required by Emerging Issues Task Force (“EITF”) No. 01-09, “Accounting for Consideration Given by a Vendor to a Customer (Including a Reseller of the Vendor’s Products),” an estimate of mail-in rebates that are paid by us directly to subscribers is recorded as a reduction to subscriber revenue in the period the subscriber activates our service. We estimate the effects of mail-in rebates based on actual take-rates for rebate incentives offered in prior periods. In subsequent periods, estimates are adjusted when necessary.
