Who he is: Sir Li Ka-shing is a Chinese businessman based in Hong Kong, currently chairman of Hutchison Wampoa Limited and Cheung Kong Holdings. In 2010 the companies he manages were worth about 15%  of the entire Hong Kong stock market, which qualifies Ka-shing as a magnate of epic proportions, rather than a mere businessman. He's commonly considered Asia's most powerful man, has the nickname Superman, and like many powerful figures associated with Facebook, he's a a dropout , having left school at 15 (though that led to 16-hour work days at a plastics company). A serial tech investor , he's philanthropic to the extent he thinks of his charity, the Li Ka-shing Foundation as his "third son ." Through it he's already given away  over $1.4 billion.
What's his connection with Facebook?: In 2007 Ka-shing poured some $120 million into Facebook for a 0.8% share at the company's then valuation of $15 billion.
What he's currently worth: Ka-shing may be the best example ever of nominative determinism--the notion that your name decides your career. He's considered the 11th richest man in the world with an estimated worth of $22 billion in 2011. Ka-ching , indeed.
What Facebook's IPO will bring: A 0.8% stake in a Facebook worth $85 billion at IPO would equate to $680 million for Ka-shing.
What he'll make at IPO: A 0.75% stake (what Ka-shing now seems to own ) at IPO will convert to $750 million at a valuation of $100 billion.
What he'll do with it: Ka-shing has recently been in the news thanks to a number of high-profile financial moves. Last week his company Hutchinson Wampoa made a bid  for Irish telecom firm Eircom with $2.6 billion on the table, and this week revealed  plans to list the first yuan-denominated real estate investment firm in Singapore. There are rumblings  that his Chinese enterprise Parknshop, cornerstone of his business fortune, may be suffering due to strengthening competition in the Chinese retail sector...so perhaps some of his money will go toward adjusting this business.
