Apple CEO Tim Cook hails Vishal Bhardwaj's short film 'Fursat' as 'Beautiful'

Cook, however, still has a long way to go to catch up with other CEOs on the Bloomberg Billionaires' list, like Amazon Founder and CEO Jeff Bezos ($187 billion), former Microsoft CEO Bill Gates ($121 billion) and Facebook CEO Mark Zuckerberg ($102 billion).

"Cook owns 847,969 shares directly and took home more than $125 million last year as part of his pay package," reports the BBC.

Cook is a bit of an unusual case among the three comma club, though, because he didn’t found Apple, and it’s rare for any non-founder CEO to become a billionaire.

He spent many years at the company and rebuilt its supply chain using “just-in-time” manufacturing principles, like reducing inventory, after Steve Jobs hired him away from Compaq to be Apple’s COO.

Cook had received restricted shares on his first day as Apple CEO and currently owns 847,969 shares, equivalent to 0.2% of Apple shares worth $375 million.

Based on Apple's stock performance in the S&P 500, he is expected to receive his 9th payout of 560,000 shares later this month.

Apple is now closing in on the milestone of being the first company to be valued at $2 trillion.

Last week, Apple surpassed Saudi Arabia's state-owned oil company Saudi Aramco to become the world's most valuable company.

Apple was the first US company to cross the $1-trillion mark in 2018.
