Class action lawsuits would bring the suitors to their knees unless FVM was acheived. Back in August 2014 the 2nd Pelligrino Report valued the company's technology/IPs at a mean value of $ 2.33B USD. So any buyout would have to be well north of the FVM from Pelligrino 2.
Geoff Taylor indicated at one time the value to be approx. $ 10B USD. So any B/O offer would need to start at $ 10/sh USD to $40'ish/share.
Consider that WHEN or IF a tender happens.
