The Facebook CEO cut his own base salary to just $1 in 2013, but the whole picture is a lot more complex.

A Slim Salary

Facebook founder and CEO Mark Zuckerberg is now the company’s lowest-paid employee, according to its latest proxy filing.

Zuckerberg, worth $27.8 billion dollars mostly in Facebook stock, requested an annual wage of $1 dollar in 2013, joining the ranks of a handful of other very wealthy CEOs who take a symbolically negligible base pay.

Google’s Sergey Brin and Larry Page, worth roughly $30 billion a piece, have been drawing a $1 salary for a decade now.
