Zuckerberg's 2013 Salary: $1

Steve Jobs did it; Google founders Sergey Brin and Larry Page did, too. Now Mark Zuckerberg is joining the ranks of the $1-a-year CEOs, Bloomberg reports. That's what the Facebook boss earned in salary last year, compared to $503,205 the year before. The low salary shouldn't hurt much, given that Zuck has a $27 billion fortune (though he did reportedly lose $3 billion last week). His total compensation last year was $653,165, much of it going to travel costs.

Even with his $1 salary, the 29-year-old brought in $3.3 billion last year, the AP reports. He exercised 60 million stock options at 6 cents per share; then, he sold 41.35 million shares at $55.05 each to cover tax expenses. His shares in Facebook—some 426.3 million, worth $25.7 billion—mean he has 61.6% voting power in the social network. He and his wife, Priscilla Chan, donated 18 million shares, worth about $1 billion, to charity last year. (More Mark Zuckerberg stories.)
