Zuckerberg Cashes in Stock To Pay Tax Bill

Mark Zuckerberg cashed in stock options worth about $2.3 billion last year, which led to an almost $1 billion tax bill, reports USA Today. 

Zuckerberg's 2013 salary will be $1, without any equity awards, which is in sharp contrast to what he reportedly made last year, $503,000. His bonus and perks were valued at about $1.4 million.
