New York, San Francisco: Tim Cook, who marked his five-year anniversary as Apple Inc’s chief executive officer on Wednesday, received shares valued at $373 million (Dh1.4 billion) during that period as the iPhone maker’s stock doubled on his watch. When Cook took the helm in 2011, he was granted 1 million shares. Originally, 50 per cent of those were scheduled to vest on his five-year anniversary, with the rest coming due after a decade with the company. That changed in 2013, when Cook voluntarily tied one-third of the award to outperforming the S&P 500 Index and the shares began vesting annually.
