At the time I started buying (approx. 2 years ago) I was able to come up with a valuation between 3 and 5 dollars per share using value investing approaches - not fool proof or anything but I had a nice margin of safety etc. Sure Buffett has his own method but he may come up with a similar range. I wonder if it was the short seller attack from the US that informed Buffett of the company if this is true.
