We have entered into an agreement with Howard Stern, one of the most widely listened to radio and entertainment personalities in the United States, and his production company. Pursuant to the agreement, commencing on January 1, 2006, Stern will move his radio show to SIRIUS Satellite Radio from terrestrial radio as part of a channel created by Stern. We also expect Stern to develop and produce one or more additional channels of programming for us during the term of the agreement. The agreement will expire on December 31, 2010.
Our financial obligations under the agreement are material, and consist of both fixed and incentive payments. These obligations are payable partly in cash and partly in shares of our common stock.
We estimate that we will recoup our fixed obligations under the agreement when we acquire approximately 1,000,000 incremental subscribers. This estimate is based upon a number of significant assumptions (which we believe to be reasonable but which contain significant uncertainties), including the timing and costs of acquiring such subscribers and the length of time such individuals remain subscribers. In addition, if we achieve the incentive milestones contained in the agreement, we believe that the material positive effects on our business will far outweigh the related incentive payments.
Our aggregate fixed obligations under the agreement are approximately $100 million per year. These costs include production and operating costs for the show, including compensation of show cast and staff, overhead, construction costs for a dedicated studio, a budget for the development of additional programming and marketing concepts, and payments to Stern and his agent.
We are also obligated to make substantial stock-based incentive payments under the agreement if we significantly exceed agreed upon year-end subscriber targets during the term of the agreement, or acquire material amounts of subscribers during the term directly and trackably through Stern's efforts. In addition, upon reaching an agreed upon number of subscribers, we will share a portion of the revenue we derive directly from advertising on the Stern channels, and the revenue we derive from subscribers acquired during the term directly and trackably through Stern's efforts.
We believe that our agreement with Stern will have a material positive benefit to our business, including a positive impact on consumer awareness, average revenue per subscriber, churn and partner relations. Nevertheless, in the event we generate substantially fewer than 1,000,000 subscribers in excess of our current plans due to the addition of Stern to our programming line-up, the large fixed obligations under the agreement with Stern could have a material negative impact on our financial condition and results of operations.
