You didn't miss a thing.
The issue is how much money we got from the J's, when they got and booked the money, if they will get more in future payments, are them or other companies now paying money out over time ( and if so when and how long) What is this special business agreement with the J's, and on and on.
They know it all and we don't have a clue........it should be out of the question for them to buy or sell any !
