Apple chief executive Tim Cook has received more than five million shares in the technology giant, as he marks ten years in the job.
It is part of a deal he struck when he took over from co-founder Steve Jobs, BBC reported.
The award depended on how well Apple's shares performed compared to other firms on the S&P 500 stock index.
According to Apple's filing with the SEC, Cook was eligible for the award as the company's shares had risen by 191.83% over the last three years.
It also noted that Apple's share price has increased 1,200% since he became chief executive on 24 August 2011.
