Would Google sell themselves off at 3 times their monthly earnings? Nup, because it'd only take the buyer 3 and a bit months... And they'd be $x-squillion in profit -- completely effortlessly. It would be a lot more profitiable for Google to keep their company, at that sort of rate.
If Google wouldn't (I'm sure you wouldn't argue with me in saying that Google have made some pretty good business choices), why would you? Compare things to scale.
Not a bad reference, but I probably wouldn't have prepared it in the same way myself.
