I saw in another post that reviewed the options, slingshot around the moon, use the satellites internal engine to raise the orbit or just deorbit. A number of times they chose to just deorbit the satellite so they could collect the insurance money as a full loss. If they did put into orbit and use it then while they'd get some insurance money it wouldn't be the full cost of the satellite.
There was another satellite in addition to the Asiasat which was saved this way, Arabsat 4, which was stranded in low orbit back in 2006 by . . . a Russian Proton 2nd stage burn anomaly! Looks like slingshot around the moon was talked about for awhile on this one too, and then they decided it wouldn't work. It's going to be quite awhile I have feeling before we know the fate of AMC-14.
