Description: According to Ventures Africa, an African business magazine and news service, the richest black woman in the world is NO LONGER Oprah Wilfrey but Nigerian billionaire oil tycoon Folorunsho Alakija. The report suggests that the 61 year-old owner/founder of Famfa oil is worth at least $3.3 billion, $500 million richer than media mogul Oprah Winfrey whose wealth Forbes magazine estimated at $2.7 billion in September. Infact, Alakija's claim in a $10.74 billion oil well is worth $6.44 billion. But the report subtracts 50% of the $6.44 billion (in a worse case scenario) since it is unknown whether or not the company has any long-term or short-term debt. In essence, If Famfa oil is debt free, Mrs Alakija will undisputedly be the world's richest black woman with $6.4 billion dollars. She is also reported to have a real estate portfolio running into hundreds of millions.It was reported earlier this year that she acquired a property at Hyde Park in London for $102 million. She also owns a Bombardier Global Express 6000 jet which she bought earlier this year for a reported $46 million.
