This means that back in December Jeff Bezos could have cashed in his shares for $58.5bn, but the markets have taken their toll, with those same shares are now worth $50.5bn.

Zuckerberg, the chairman, chief exec and founder of social networking giant Facebook, is worth $47.1 billion. He currently owns around 24% in the networking giant.
