I think its an ugly situation that these two entities have been structured so any rewards go to the shareholders and especially executives and risks get moved to the taxpayers. These entities should be nationalized immediately, the execs and all their lobbyests put on the street, and, like other companies that have gone down in flames, shareholders should get away with little or nothing.
In a case of "I told you so", The Economist in this weeks issue says the same thing. It recommends nationalizing them now, then reconsidering their status when the situation improves.
