That's a move by a very interested party willing to pay it forward in that instance. I saw it as well. No idea what it could mean but the party showed serious trust, very strong interest and goodwill to prepay with terms to follow.
It's certainly not a prepayment for an interest in the lawsuit partnership. Those terms are fixed.
It's not a prepayment for C Shares. The 10Q states that 45000 C shares were converted into common stock in accordance with their terms
AND further, the 10K and Q clearly state that the only securities that the company currently has for sale are the C Shares so the $3 million prepayment must be for securities in something new for which the terms are in the process of being finalized.
I'm guessing it could be something really exciting for someone or some company or some institution to prepay $3 million for a PLACEHOLDER!!!!
