On the OTL board, we were reminded that NAVB and PM made a deal in Dec 12 for PM to extend warrant conversions until later and also converted some common back into preferred. This avoided exceeding the 10% ownership. So selling is still theoretically possible, but their are other ways for PM to keep their shares under 10%.
Don't bite on this one, z3peru. You have been in this stock for a long time and seen much. Only been in about 4 yrs. Let them play. Navb has transformed itself from Bupp days, and the payday will come.
