Context
A 10b5-1 trading plan allows insiders to sell shares according to a preset schedule or rules and is commonly used to avoid the appearance of trading on inside information. Such prearranged sales are generally treated as routine dispositions; they do not necessarily indicate the director’s current view of the company’s prospects.
