Dropped off last year's list, after shares in Gulf Bank plummeted due to nearly $1 billion loss from derivative trades in October 2008. Brother Kutayba first replaced him as chairman, then in 2009 Ali Al-Rashaid Al-Bader took over. Comes from Kuwait's sovereign fund, which picked up a 16% stake to shore up the bank. Aggressively bulked up on provisions against bad loans, and bank finally turned a profit in the first nine months of 2010. Alghamin remains involved in family holding Alghanim Industries, with interests in manufacturing, advertising and shipping--among others. According to Forbes, Alghanim — the 68-year-old heir of a now-deceased Kuwaiti industrialist — boasts a personal net worth at $1.4 billion. For decades, he’s lived a quiet life in Bel Air California, occasionally forking out several million dollars to buy one of his neighbor’s homes. With the acquisition of Joe Francis’s estate, his mega-sized, 10-parcel Bel Air compound now spans 21+ contiguous acres and includes no fewer than seven houses, one of them scooped up this past April for $11 million. Today, the entire spread is likely worth north of $100 million. Alghanim’s main Bel Air residence — an 11,000 sq. ft. Mediterranean-esque structure — sits on its own private, gated street just across the way from an ersatz mansion that was long called home by the late, great Zsa Zsa Gabor.
