Context

• 10b5-1 plans are pre-arranged trading programs that allow insiders to sell shares on a set schedule; transactions under such plans are generally considered routine and may not reflect the insider’s current view of the company. This sale is modest in dollar terms and does not, by itself, indicate a change in the director’s long-term position.
