Despite signs of a weakening stock market and a company stock that is less than $30 away from its 52-week low, a group of Apple senior executives -- including CEO Tim Cook -- opted to sell restricted stock unit (RSU) bonus awards they received two years ago that recently vested. On average, five of the six leaders grossed about $15 million, with Senior Vice President of Technologies Bob Mansfield selling less stock and gaining about $6 million for a grand total among the group of $86.45 million. In addition, Cook asked the board to tie his RSUs more closely to company performance.
