One additional note, the conversations were done in person but no paper work was produced and Lehman was never mentioned as issuing bank, the implication was always that these were products backed by Citibank. After my father had agreed to invest in these products he signed some single sheet of paper that did not have Lehman on it anywhere and then in the mail some time later received something, maybe a statement?, that has the name lehman attached to the instrument, unfortunately he had no idea that Lehman was a bank, to him it was just another term like Bono. I think that it is pretty clear on the face of it that Citibank and apparently many other banks have been trying and succeeding in pulling a fast one.
True that people should read everything that they sign but not sure that absolves Citibank of its fiduciary responsibility to deal forthrightly and ethically with thier clients. You shouldn't have to guard against your private banker's advice as though he were a snake in the grass.
I can just imagine the conference calls from New York telling the international private bankers in countries where they thought they could get away with this stuff (I wonder how many in the us were sold these, probably not too many due to liability) to unload as much Lehman crap on as many suckers as they could by any means necessary. I have now found out that they were still selling this stuff in Italy as late as a week before Lehman went tits up with no mention of Lehman being the guarantor!
Sometimes you pick a person who can make sure that what comes around indeed goes around.
