Mr Cook was appointed CEO last week following Mr Jobs' resignation from the top job at Apple (Mr Jobs continues as an Apple employee and has become chairman of the company). On Friday Apple disclosed that Mr Cook has been granted 1 million shares in the company, providing he stays the course. The first tranche of 500,000 shares will vest if he is still with the company in five years time, and the remainder five years after that.
Those shares are currently valued at $US383.58 million. That gives Mr Cook a considerable incentive to at least maintain the value of Apple shares, which is presumably in line with what investors want.
The five and ten year thresholds should encourage him to take a long-term view, at least until this decade is out.
