For those to whom this is merely a lot of mumbo-jumbo, let me explain in layman's terms:
AIG, knowing it would need to ask for much more capital from the Treasury imminently, decided to throw in the towel, and gifted major bank counter-parties with trades which were egregiously profitable to the banks, and even more egregiously money losing to the U.S. taxpayers, who had to dump more and more cash into AIG, without having the U.S. Treasury Secretary Tim Geithner disclose the real extent of this, for lack of a better word, fraudulent scam.
How the melt down actually works (and why Citi reported a profit last quarter), in relatively simple terms.
