Control
Currently, Musk holds about 15% of Tesla’s shares, which coincides with about 15% voting control. In his mind, that number is too small to ensure his job security, so the board has structured the comp package with increasing stock awards that over time could get him up to 25% voting control.
At that quarter-level of voting control, Musk believes he would maintain his role if he is doing a good job, while still allowing shareholders to fire him if, in his words, he “goes insane.”
From his perspective, the concern about his comp package is “asinine,” since as he hits his milestones, investors will be increasingly rewarded along the way.
