How much Apple pays to protect Tim Cook

Mark Zuckerberg's security provisions define personal expenditure quite liberally. Not only does Facebook (FB) account for his private security, but also "costs related to personal use of aircraft chartered in connection with Mr. Zuckerberg's overall security program and on which Mr. Zuckerberg and guests flew."

Depending on how many guests Zuckerberg has flown across the country and how stringent the security for his friends and family was, the number could be really close or really far from the $610,000 figure.
