Carlos Slim Helu & family
Net Worth - $51.4 Billion
Carlos Slim Helu, the world's second richest man in 2015, hit some headwinds in the past year. Shares of his pan-Latin American mobile phone operator, America Movil, took a beating in 2015 and early 2016 in the wake of new Mexican telecom regulations, a weaker Mexican peso and economic decline in Brazil. That drove a $27.1 billion drop in Slim's net worth, making him the biggest dollar loser on the 2016 Forbes Billionaires List.
