Many prominent executives in Apple (AAPL) have been cashing in blocks of company stock for major payouts. As the company’s shares reached $617.62 yesterday, the soaring share price appears to have motivated some executives at the Cupertino, CA company to sell stock options as they vested for major paydays. In total, over $300 million in stock has been sold by five top executives. Most of the stock sold came in the form of Restricted Stock Units, or RSUs, which are generally awarded a little over four years ago and just vested.

“The Company believes long-term equity awards in the form of RSUs are the most effective way to attract and retain a talented executive team and align executives’ interests with those of shareholders,” the company said through its proxy.

Apple CEO Tim Cook sold close to 240,000 shares for approximately $140 million. Also selling shares were CFO Peter Oppenheimer, who cashed in 150,000 shares for about $90 million, marketing chief Phil Schiller, who sold shares to the tune of $72 million, and hardware chief Bob Mansfield and mobile software head Scott Forstall sold about $33 million worth of stock each.
