FCC regulation or XMs failure to comply with FCC requirements could damage XMs business.
XM holds FCC licenses and authorizations to operate a commercial satellite radio service in the United States, including authorizations for satellites and a terrestrial repeater system, and related authorizations. The FCC generally grants licenses and authorizations for a fixed term. Although XM expects its satellite licenses and authorizations to be renewed in the ordinary course upon their expiration, there can be no assurance that this will be the case. Any assignment or transfer of control of XMs FCC licenses or authorizations must be approved in advance by the FCC.
The operation of XMs system is subject to significant regulation by the FCC under authority granted through the Communications Act and related federal law. XM is required, among other things, to operate only within specified frequencies; to meet certain conditions regarding the interoperability of its radios with those of the other licensed satellite radio system; to coordinate its satellite radio service with radio systems operating in the same range of frequencies in neighboring countries; and to coordinate its communications links to its satellites with other systems that operate in the same frequency band. Non-compliance by XM with these requirements or other conditions or with other applicable FCC rules and regulations could result in fines, additional license conditions, license revocation or other detrimental FCC actions. There is no guarantee that the FCC will not modify its rules and regulations in a manner that would have a material impact on XMs operations.
XM is operating its terrestrial repeaters on a non-interference basis pursuant to grants of STA from the FCC, which have expired. XM has applied on a timely basis for extensions of these STAs. Pursuant to FCC rules, if an extension request is filed on a timely basis, operations in accordance with the terms of the STA may continue pending action on the extension request.
