How much Apple pays to protect Tim Cook

Security for Amazon's (AMZN)head honcho is the priciest of the lot. For the last three years, Bezos has had a $1.6 million security budget above and beyond the security "at business facilities and during business-related travel."

Amazon technically pays him a salary of $81,840. The company believes that "the amount of the reported security expenses is especially reasonable in light of Mr. Bezos' low salary and the fact that he has never received any stock-based compensation," according to an regulatory filing.
