Ages ago IGS gave Sante Fe a very sizable loan for a merger but that fell through. Then it was in hopes that they could produce at a profit and IGS would see a small gain from the loan returns. Assuming the news story is correct, that has obviously not happened. I haven't been follow it recently so I don't know how large it is now but it was in the millions. Pretty sure they converted some notes too so they have (now worthless) shares.
