Amazon spent $1.6 million on security for CEO Jeff Bezos last year, accounting for nearly all of his compensation.
The money went to providing security for Bezos in addition to what is available at Amazon facilities, such as for business travel, according to a filing by Amazon with the Securities & Exchange Commission on Wednesday.
In all, Bezos collected $1.68 million in compensation last year. Bezos earned only $81,840 in salary for the year and no stock options.
Bezos is Amazon's largest shareholder and is listed by Bloomberg as the world's second richest person, with a net worth of approximately $75.6 billion.
Amazon spent a similar amount for Bezos' security in 2015. The company also said that in light of his low salary, the security expenses in 2016 were reasonable.
