Context
Sales made under an established 10b5-1 plan are pre-scheduled and do not necessarily reflect the insider’s current view of the company; they are commonly used to avoid allegations of trading on material nonpublic information. The presence of unvested restricted stock units in the filing indicates additional future equity exposure, but those RSUs have not yet been delivered.
