Dollarswealth,
I will tell you a method that can be used but having spent many hours researching CNP I don't give advice on valuations to people not prepared to do the hard yards.
If you truly want to learn about investing do your own research & build models to determine valuations.
I personally would not take a valuation offered on Hotcopper as accurate, hence the reason to question their method in the first place.
To many amateurs post misleading information on CNP that causes other less experienced investors to make wrong assumptions.
