Both were prepackaged bk's. GM was given to govt, union and bondholders and CIT was given to bondholders. The crappy thing about CIT was immediately after exiting BK, they marked their assets up.
If LEH can show that they dont have enough money for the most senior claims, then they dont have to pay out the rest. I think the key would be to get info on the assets and make sure they have fairly valued them. If I remember correctly, Vakulas's report stated they were fairly valued, but i believe the number he was going off of was the $200+ billion.
The cynic in me says that LEH has devalued the assets to $60-70 billion and that the senior claims will end up with all equity in LAMCO which will inherit all assets. They will probably slowly mark assets back up until full value and we will end up holding the bag.
