NUMBERS DON'T LIE

Carlos Slim Helu is the world's richest man for the fourth year in a row. He clocks in at $4 billion more than a year ago, thanks to surging stock prices at his financial arm, Grupo Financiero Inbursa, and at his Grupo Carso industrial and retail giant. Pan-Latin American mobile telecom outfit America Movil remains his most valuable holding at $36.3 billion.
