This is another fallacy that's been peddled here for a long time but is actually inaccurate, as per Pq and Kq prospectus's.
Neither the Pq's nor the Kq's were ever directly backed by any Trusts or Trust assets,... only the TPS, now referred to as Reits were.
When the exchange event occurred in September, 2008, those assets immediately became WMB property and were subsequently acquired by JPM.
Dividends paid to Pq's and Kq's came from the profits generated by the whole company, WAMU, same as the dividends received by Commons.
These profits would have been partly generated from retained SH assets that we hope are still there and will be returned to our Markers.
