Mark Zuckerberg made $3.3 billion on Facebook stock in 2013

Mark Zuckerberg earned $3.3 billion on the sale of his Facebook share options in 2013, a new regulatory filing has revealed.

The Facebook founder has now exhausted his supply of stock options as a result of the social networking’s public offering.

Mark Zuckerberg was given 60 million shares to help him with his tax bill.

His base salary for 2013 fell to $1, like other tech leaders such as Google’s Larry Page and former Apple boss Steve Jobs.

However, Mark Zuckerberg’s total compensation for 2013 was $653,165, down from $1.99 million in 2012.

Facebook said the majority of that was to pay for flights on private jets, which are seen as necessary for security reasons.

Mark Zuckerberg still owns 426.3 million Facebook shares, which are worth around $25.7 billion.

Facebook shares have more than doubled in value over the past year, as the social networking has reported better than expected earnings due to its strong mobile ad sales.
