A restricted stock unit, or RSU, is a form of compensation valued in terms of company stock, but the stock is not issued at the time of the grant. Instead, it's meant as an enticement for senior management to stay with the company. The shares in question were originally awarded in September of 2008, likely as part of an annual bonus. When they vested on March 24 of this year, each RSU was converted to a single share of AAPL stock.
The executives used a Rule 10b5-1 trading plan to manage the sales of the shares. The regulation allows executives with insider knowledge of the company to control the purchase or sale of stock ahead of time so as to avoid any accusation of insider trading.
Apple executives Bob Mansfield and Scott Forstall also had large RSU awards vest this month, but their shares weren't sold immediately.
