Forbes said, “To compile net worths, we value individuals’ assets, including stakes in public and private companies, real estate, yachts, art and cash – and account for debt.
“We attempt to vet these numbers with all billionaires. Some cooperate; others don’t. We also consult an array of outside experts in various fields.”
The past year has been eventful for Dangote. In October, he sold off a controlling stake in his flour milling company to Tiger Brands of South Africa and pocketed $190m in cash.
In February, his Dangote Sugar Refineries acquired a 95 per cent stake in Savannah Sugar in a bid to maintain its dominant position in the Nigerian sugar industry.
Dangote started building his fortune more than three decades ago when he began trading in commodities like cement, flour and sugar with a loan he received from his maternal uncle.
He delved into full production of these items in the early 2000s and went on to build the Dangote Group, West Africa’s largest publicly-listed conglomerate, which now owns sugar refineries, salt processing facilities and Dangote Cement.
