 Mark Zuckerberg has decided he’s a $1-a-year man. 
 
 Zuckerberg, who is Facebook Inc. (FB:US)’s chief executive officer and also the 22nd richest person in the world as ranked by the Bloomberg Billionaires Index, was paid $1 in salary for 2013, according to a regulatory filing with the U.S. Securities and Exchange Commission yesterday. That’s down from a base salary of $503,205 in 2012, the year that Facebook went public. 
 
 Zuckerberg is following the well worn path of other Silicon Valley technology moguls who also chose to take on the symbolic annual salary of $1 after they were already wealthy. Apple Inc.’s late co-founder Steve Jobs helped popularize the practice, which is today also espoused by Google Inc. co-founders Larry Page and Sergey Brin, among others. All own sizable equity stakes in their own companies.

 Zuckerberg, whose wealth totals around $27 billion, owns Facebook shares that give him 61.6 percent of voting power in the Menlo Park, California-based social network, according to the filing. He saw his net worth balloon last year as Facebook’s stock more than doubled (FB:US) in value. The 29-year-old has ramped up his public service and philanthropy, including starting a group called Internet.org to connect the world to the Web. 
 
 Private Planes 
 
 Zuckerberg’s total compensation last year was $653,165, down from $1.99 million in 2012. The amount, besides the $1 salary, was for the passenger fees, fuel, crew and catering costs for his use of private planes for personal reasons, as part of his security program, according to the filing. 
 
 The CEO also made $3.3 billion last year after exercising stock options to purchase 60 million shares, according to the filing. Zuckerberg offered 41.35 million of those shares in a secondary offering by Facebook in December. At the time, the company said Zuckerberg would use the majority of the proceeds to pay for the taxes incurred in connection with the transaction. He also gifted 18 million shares to charity. 
 
 Other Facebook leaders also saw their compensation fall from 2012 levels. Chief Operating Officer Sheryl Sandberg received $16.2 million in total compensation in 2013, compared with $26.2 million a year earlier. She became a billionaire in January as Facebook’s shares soared, according to the Bloomberg Billionaires Index. 
 
 Chief Financial Officer David Ebersman made $10.5 million in compensation last year, compared with the $17.5 million in 2012. Vice President David Fischer’s compensation totaled $8 million last year, down from $12 million in 2012, while Chief Technology Officer Mike Schroepfer gained $12.6 million last year, down from $20.7 million a year earlier.

 The windfall saddled Zuckerberg with a huge tax bill, even though he limited his Facebook salary to just $1, according to regulatory documents filed Monday. 
 
 It marks the second straight year that Zuckerberg has realized a huge gain on the holding that he has accumulated in Facebook Inc. since he started the company in 2004. In 2012, Zuckerberg made $2.3 billion off his stock options. 
 
 Zuckerberg, 29, now has exhausted his supply of stock options after exercising 60 million of them last year a price of 6 cents per share. He then sold 41.35 million shares for $55.05 apiece in December, primarily to pay for his tax bill on the gains. 
 
 Zuckerberg and his wife, Priscilla Chan, also donated 18 million Facebook shares to a Silicon Valley nonprofit. The December gift, then valued at nearly $1 billion, landed the couple at the top of The Chronicle of Philanthropy's annual list of the most generous Americans. 
 
 Even after selling and donating so much Facebook stock, Zuckerberg still owns 426.3 million Facebook shares currently worth $25.7 billion. The stock has more than doubled in value during the past year as Zuckerberg fulfilled his promise to sell more ads on the smartphones and tablet computers that bring in most of the traffic to Facebook's social networking service. 
 
 The Menlo Park, Calif., company now gets more than half of its ad revenue from mobile devices, up from 23 percent at the beginning of last year. 
 
 Like many company founders who have gotten wealthy off their early stakes, Zuckerberg asked Facebook to limit his annual salary to $1 annually. Besides that token sum, Zuckerberg also received perquisites valued at $653,164. All but $3,000 of that amount went toward Zuckerberg's bills for personal travel on chartered jets. 
 
 Excluding stock option gains, Zuckerberg's total compensation last year plunged 67 percent from nearly $2 million in 2012. 
 
 The Associated Press formula calculates an executive's total compensation during the last fiscal year by adding salary, bonuses, perks, above-market interest that the company pays on deferred compensation and the estimated value of stock and stock options awarded during the year. The AP formula does not count changes in the present value of pensions, a benefit that Facebook and most other technology companies don't provide.
– 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.
