So it was a failure on E3 a couple of months ago...
EchoStar III. EchoStar III was originally designed to operate a maximum of 32 DBS transponders in full continental United States ("CONUS") mode at approximately 120 watts per channel, switchable to 16 transponders operating at over 230 watts per channel, and was equipped with a total of 44 traveling wave tube amplifiers ("TWTAs") to provide redundancy. As a result of TWTA failures in previous years and an additional pair of TWTA failures during August 2009, only 16 transponders are currently available for use. Due to redundancy switching limitations and specific channel authorizations, we are currently operating on 14 of our FCC authorized frequencies at the 61.5 degree orbital location. While the failures have not reduced the original minimum 12-year design life of the satellite, it is likely that additional TWTA failures will occur from time to time in the future, and such failures could further impact commercial operation of the satellite.
EchoStar XII. Prior to 2009, EchoStar XII experienced anomalies resulting in the loss of electrical power available from its solar arrays. During March and May 2009, EchoStar XII experienced more of these anomalies, which further reduced the electrical power available to operate EchoStar XII. We currently operate EchoStar XII in CONUS/spot beam hybrid mode. If we continue to operate the satellite in this mode, as a result of this loss of electrical power, we would be unable to use the full complement of its available transponders for the 12-year design life of the satellite. However, since the number of useable transponders on EchoStar XII depends on, among other things, whether EchoStar XII is operated in CONUS, spot beam, or hybrid CONUS/spot beam mode, we are unable to determine at this time the actual number of transponders that will be available at any given time or how many transponders can be used during the remaining estimated life of the satellite. Additionally, there can be no assurance that future anomalies will not cause further losses, which could impact the remaining useful life or commercial operation of EchoStar XII. As a result of the May 2009 anomalies on EchoStar XII, we determined that we had a triggering event related to EchoStar XII. See discussion of evaluation of impairment in "Long-Lived Satellite Assets" below. Based on this triggering event we performed an impairment review of the satellite using an undiscounted cash flow model and concluded that the estimated undiscounted cash flows associated with EchoStar XII were still in excess of its carrying value and therefore no impairment was required.
