Apple CEO Tim Cook has reached billionaire status, according to the Bloomberg Billionaires Index. As Apple's share price climbed nearly five percent last week, the company's market value is now around $2 trillion, making it and Cook more valuable than ever.

Cook's net worth is predominantly made up of his Apple salary, as well as shares in the company and proceeds from his share sales. He currently has 847,969 Apple shares, worth more than $380 million. As of last year, Apple paid Cook a $3 million base salary, with $7.6 million in incentive pay, making him one of the highest paid CEOs in the United States, although certainly not at the level of his fellow tech CEOs Jeff Bezos and Mark Zuckerberg. Cook is not a founder-CEO like many of his counterparts, which is partly why his net worth is considerably lower.

Cook became the CEO at Apple in 2011 as he took over for the legendary Steve Jobs. The company was valued at roughly $350 billion when Jobs passed away, and is — again — now hovering around $2 trillion.

Back in 2015, Cook said he plans to give most of his fortune away. He has already donated millions of dollars in Apple shares.
