In general the quoted sales price in the trust announcements does include the liquids (some trusts like PBT are specifically highlighting that in the distribution announcement now). However my understanding is that SJT (and HGT) have minimal liquids - it's pretty much all dry gas.
I don't see the point of trying to figure this to the nearest penny. The previous poster said his calculations showed a 0.17c discrepancy to what the price should be. That's not all that material when the price drops from $4.50 to $2.50. We may not know to the nearest dime but we know the prices received by the trust will be significantly lower in the next couple of distributions.
