Slayton: no one knows. everyone has the same question. The answer will determine who wins and who loses this game. Folks are trying real hard to answer, but the fact is, nothing is or can be confirmed about the bonds except they do exist. They either paid for it ( how, don't know) , it was given to them (why, don't know), it was assigned to them ( why, don't know). Obvioulsy the only way it can be as asset is if it was bought or given to them, otherwise it's being provided to them to use as a credit enhancement ( collateral) to establish lines of credit to fund their businesses.
Obviously if this was all neat and confirmed to be a free and clear asset prior to hypothecation, we wouldn't be at a buck. So, place your bet. jmo
