Domsam,

I have no idea which unit of Ambac is buying back the debt, but it's a good sign. The lawsuits could drag out for years and the commutations will take place as the defendants decide it's better to negotiate than fight it out in the courts. The Yahoo/Ambac website is not for serious investors. it's been taken over by traders and short sellers. It does has some entertainment value, but that's about it.
