Bob Mansfield, Apple&39's senior vice president of Macintosh hardware engineering.

Bob Mansfield, Apple's senior vice president of Macintosh hardware engineering, sold off 99 percent of his company shares earlier this week, a sale amounting to just under $13.7 million.

Mansfield, who joined Apple when the company acquired Raycer Graphics in 1999, now owns 501 shares following the sale according to a Form 4 filed with the SEC on Monday.

But that doesn't mean he's divesting himself from the company. Fortune reports that Mansfield still holds fully vested options to buy 30,000 more shares of company stock at $36.54 per share, along with an additional 100,000 restricted stock units that vest in 2014.

Mansfield's last big sale was 40,000 shares of company stock back in October, netting $10.84 million after strike price. In the past three years, Fortune estimates the net gain from these trades at $37.9 million.

Along with Mansfield's transaction this week, Apple Vice President and Corporate Controller Betsy Rafael sold 2,956 shares of common stock on the same day.
