From the 10Q:
EchoStar XII
[FONT="]EchoStar XII, which we purchased in orbit from a third party during 2005, currently operates at the 61.5 degree orbital location. The satellite was originally launched during July 2003. EchoStar XII was designed to operate 13 transponders at 270 watts per channel, in CONUS mode, or 22 spot beams using a combination of 135 and 65 watt TWTAs. We currently operate the satellite in CONUS mode. EchoStar XII has a total of 24 solar array circuits, approximately 22 of which are required to assure full power for the original minimum 12 year design life of the satellite. Prior to our purchase, two solar array circuits failed, one of which was subsequently restored to partial use. Between February and April 2006, two additional solar array circuits failed. The cause of the failures is being investigated. While the design life of the satellite has not been affected, in future years the power loss will cause a reduction in the number of transponders which can be operated. The exact extent of this impact has not yet been determined. There can be no assurance future anomalies will not cause further losses, which could further impact commercial operation of the satellite or its useful life.
