RE: Further to my last.I wouldn't worry about that. Remember Xign is on the balance sheet at cost. This thing will not be taken over anywhere close to $3.00. Everyone at the company is aware that this should be trading north of that let alone be taken over at that.
Personally I doubt a takeover is the issue at all. I think it probably has to do with Xign IPO news getting out. I can't picture RDM selling before that IPO is done; at least not in a friendly takeover.
