WEE CHO YAW By the time he steps down as chairman of United Overseas Bank in April 2013, Wee will have spent almost four decades at the helm of Singapore's largest bank by market capitalisation. Wee, who will continue to advise the bank in his honorary role as chairman emeritus, oversaw UOB's expansion from a lender with just one branch in Singapore into a regional giant with operations in Singapore, Malaysia, Thailand and Indonesia. Wee is ranked third on Forbes' list of Singapore's 40 Richest and 290th on its list of The World Billionaires, with a net worth of US$4.7 billion. He became chairman and chief executive of UOB in 1974, but handed over his CEO position to his son, Wee Ee Cheong, in 2007. In April 2012, the Wee family's private real estate unit, Kheng Leong, submitted the top $245 million bid for a plot of land at Fernvale Lane that is slated for residential development.
