"I suppose it is possible that Samsungs obligation is to buy an equity stake in EDIG on the open market and that explains the volume but wouldn't EDIG just sell them authorized but not issued (in the float) shares?"

How about, Samsung is to going to buy an equity stake in EDIG, from authorized shares, with the "obligation" to buy a certain percentage on the open market, maybe 10m, or so.

Just speculatin',
