Looking through some things I haven't checked into for a while, including NGHO and PLNU.
Things are, in a word, bad.
As it stands now,NGHO is a shell carrying over $8 million in debt. Jaques Mot is still running the show as far as I can tell, but the last 10-Q was filed on 8/14/2009. If you came here looking for a shell, there are cleaner ones out there.
PLNU is doing even worse it seems. According to the latest 10-Q and 8-K filings they are failing to make interest payments, are swimming in debt, and have holders of convertible preferred stock lining up to get their money. Oh, and they are planning a "reorganization" in which (among other things) they will no longer trade in US markets but move to a European exchange.
Time will tell how all this will end, but I suspect that it won't end well.
