"partial compensation from the sale of certain project holdings in 2010"
You just answered your own question...
And that definitely means they have currently have an equity stake how?
Yes, yes...one can infer it means that the T&C's of the sale purchase agreement has not been satisfied and thus they some claim to equity. Which is exactly, IMO, what they want to allow people to believe who are inclined to do so. A little smoke, a few mirrors.
So as I said earlier it comes down to how one WANTS to interpret it.
But the simplest plain reading is that they sold the equity. It is gone. To interpret otherwise takes some logical gymnastics to get there based on what they said.
For the life of me, if they indeed retained that interest until ALL payments are made...or part of it...why don't they just say that?
For pink/grey stocks what is NOT SAID is ALWAYS more important than what IS SAID.
