Scenarios that could endanger a CEO range from the macro—a defense company's manufacturing of drones could make its CEO a target of the Islamic State, says Timothy Horner, head of Kroll's security risk management practice—to the micro, a "crazy niece or nephew," Horner says. Not only do those threats pose danger to individual executives, but such events could be devastating for a company's financial health. So it's no wonder that some of the nation's most prominent companies pay a pretty penny to ensure their leaders stay out of harm's way. Which company shells out the most? According to analysis of Fortune 100 data in the upcoming 2014 Benefits and Perquisites Report by Equilar, which tracks executive compensation, it's Amazon. The online retailer paid $1.6 million in 2013 for security perks for founder and CEO Jeff Bezos, whose personal worth totals an estimated $28 billion. What kind of security can that much money buy? Amazon isn't telling.
