Horseb4CarT, Vator and Sky—thanks for your replies regarding future acquisition buyout value etc
Previously (perhaps 6 years ago?) I did my own Discounted cash flow Analysis (yes, many many assumptions involved) and derived what I believed would have been a fair value —at that time I had arrived at $42/share—which I posted—-but the number of shares have doubled since then and so I would recast a buyout value of around $21/share.
