Research the new CEO James Norrod. The last 3 companies he was CEO of all got bought out. Zhone brought him in last year, specifically to manage a buy out IMO. PPS when he was hired was 2.75, without doing any DD on the financials you would think that the buy out would atleast be higher than that. I'm thinking $4-6, that's just a shot in the dark though. You can tell by the slow low volume decline that this is being brought down on purpose for accumulation.
