One reason that apparent YIELDS should be higher on the royalty trusts is that they are depleting assets. The reserves can only be sold once. Sure, there will still be some distribution from SJT. But is will actually be a Return of Capital. With NG price of $2.00 and unit price of $20.00 it is impossible to get the invest back with a profit of any type, and maybe not even possible to get the investment returned through distributions. At a $10 unit price a buyer will have at least a fighting chance for profit, provided NG prices improve quite a bit from current levels.
