Context
A 10b5-1 plan lets insiders sell according to a pre-set schedule, often to create an orderly, non-discretionary disposition and to avoid trading on material nonpublic information. Sales under such plans are generally considered routine and do not, by themselves, indicate management sentiment about the company's prospects.
