Sirius XM Radio (SIRI)

Indefinite Life Intangible Assets

We have identified our FCC licenses and the XM trademark as indefinite life intangibles after considering the expected use of the assets, the regulatory and economic environment within which they are being used, and the effects of obsolescence on their use.

We hold FCC licenses to operate our satellite digital audio radio service and provide ancillary services. SIRIUS’ FCC license for most of its satellites expires in 2010 and the license for one of its new satellites expires eight years after SIRIUS certifies the satellite is operating; XM Holdings’ FCC licenses for its satellites expire in 2013 and 2014. Prior to the expirations, we will be required to apply for a renewal of our FCC licenses. The renewal and extension of our licenses is reasonably certain at minimal cost. The FCC licenses authorize us to use the broadcast spectrum, which is a renewable, reusable resource that does not deplete or exhaust over time.
