Just had another thought after re-checking my numbers.  I couldn't find a recent value of LLC, so I assumed it was/is worth approx. US$718m, the booked value of the land rights as of Q3 2016.  Shareholder value may be less, so let's just say $700m. I suspect LLC's net worth is higher than that.  CCC's 15% investment in LLC would then be worth $105m.  

So, wouldn't a new investor coming in to replace CCC need to put up $105m? Anyone have any thoughts?

Maybe CCC is staying in, but at just 1/2 their investment.  At any rate, all of this will be cleared up with an 8k update advising new investor and how much.  No matter how you slice it, this will provide an enormous boost to LLC's financial flexibility and ability to execute on this project ... and immediately so!  Hurrah!
