Can someone explain to me why some of these goldman structured products (pyc, hjj, hyl, hyk, jzc) which are exchange traded products which hold goldman sachs debt in a trust are trading at massive discounts to gs-b, the other goldman preferrds, and the debt they hold. These things are yielding in the mid 7%s while the debt they hold trades in the mid 5%s. Why are these things not trading near 24 or 25?
