It costs $5M to keep Zuckerberg safe, and four other things we learned from Facebook - CNET

Lots of people want your attention when you're the fourth-richest person in the US and the 19th most powerful person on the planet (according to Forbes). That's why Zuckerberg has a security detail, or "program" in Facebook parlance, to address potential conces.

According to Facebook, there have been specific threats made against him. So the company has security measures in place at Zuckerberg's personal residences (plural) and pays for his security persoel. Zuckerberg also has a private airplane covered under this program. All told, it costs more than $5 million per year.

This year, Facebook began reporting security for Sandberg as well, which cost nearly $1.3 million. The company didn't say whether she gets a plane, too.

3. Some shareholders want an equal vote

Facebook is called a "controlled company," meaning Zuckerberg has ultimate control. That's not just because he owns a lot of Facebook shares, but also because he has special "Class B" shares, which have 10 votes per share. Now, Facebook is preparing to offer a new "Class C" stock, which are non-voting.

Some shareholders don't like this arrangement and are putting forth a proposal for the shareholder meeting to make all shares equal.

"Without a voice, shareholders caot hold management accountable," the shareholder proposal reads.

Of course, Zuckerberg disagrees with this. In a conference call with analysts, he noted that his control of the company allowed him to resist pressure to sell early on.

"Facebook has been built by a series of bold moves," he said. "And when I look out at the future, I see more bold moves ahead of us than behind us."

Shareholder proposals like this, particularly in successful tech companies, don't often pass.

4. You won't hear about Oculus sales any time soon

Those Oculus VR goggles that Zuckerberg believes will herald the next major stage in computing may indeed change the world. But that doesn't mean they will any time soon. Wehner said in an interview that it is "too early" to discuss sales of the Rift headset, which began arriving on customers' doorsteps March 28. It is also too early to tell when Facebook might start talking about Oculus sales.

Wehner later said Oculus won't have a "material" impact on sales this year. And Zuckerberg repeated his common refrain that while VR promises to big, it will have a slow start.

"We don't expect VR to take off as a mainstream success right away," he said. "I really want to emphasize that."

Noted.

5. Zuckerberg feels a duty to fix the world

In December, Zuckerberg aounced the birth of his first child, Max, and the creation of a $45 billion philanthropic effort called the Chan Zuckerberg Initiative. At the time, he said the organization will focus on "improving this world for the next generation."
