DirectTV sells receivers and satellite dishes and provides satellite television programming to customers. DirectTV enters into a transaction with Customer X (X) where X purchases a satellite dish and receiver and signs a contract to receive one year of satellite programming years (expected customer relationship period is three years). X installs the satellite dish and receiver itself. Amounts to be paid by X include a $50 upfront, nonrefundable fee and $18 per month for the duration of the contract (the $18 per month charges are legally enforceable). The costs incurred by DirectTV include: 1) $150 related to its purchase of the receiver and satellite dish from a third party. 2) $100 commission paid to an internal employee dedicated solely to selling activities. 1.
