The base salaries for all of Facebook’s top executives were divulged in the company’s Wednesday S-1 filing. Here’s how it broke down:

Mark Zuckerberg, CEO: Zuckerberg made a salary of $483,333 in 2011, in addition to a $220,500 bonus for the first half of 2011. He also received “other” compensation — which covers such things as chartered travel costs and security details — that totaled $783,529. Overall, Zuckerberg received $1,487,362 for 2011, excluding his substantial stake in the company.

Effective Jan. 1, 2013, Zuckerberg will reduce his base annual salary to $1.

Sheryl Sandberg, COO: As important as Mark Zuckerberg is to Facebook, the S-1 filing also reveals that the company is very concerned about keeping its chief operations office, Sheryl Sandberg.

Losing Sandberg, who has often been identified as the “grown-up” public face of the company, would be a big blow to the social network.

The document also reveals that if Sandberg is “terminated without cause” for a reason other than death or disability, she will be able to vest her stock immediately. Losing Sandberg (or Zuckerberg) is also listed as a risk for the company.

“The loss of key personnel, including members of management as well as key engineering, product development, marketing, and sales personnel, could disrupt our operations and have an adverse effect on our business,” the filing said.

Sandberg had a salary and bonus of $381,966 in 2011, but was also granted about $30 million in stock awards.

David Ebersman, CFO: David Ebersman, one of the most important Facebook executives that you’ve never heard of, also made $381,966 in salary and bonuses. With stock, his total compensation comes to $18.6 million.

Mike Schroepfer, VP of Engineering: Mike Schroepfer, the vice president of engineering, made $333,833 in salary and bonuses in 2011. Combined with his bonus and stock awards, he made $24.7 million last year.

Theodore W. Ullyot, VP, General Counsel and Secretary: Theodore Ullyot made $749,583 in salary and bonus and was granted about $6 million in stock awards and $110,644 in other compensation. As the company’s general counsel, he has the same provision in his employment agreement as Sandberg — if he’s ever terminated without cause, he will be able to vest his shares immediately.
