Context These entries reflect director compensation (restricted stock units), not an open-market purchase or sale. RSUs are a common non-cash board compensation and represent a contingent right to receive shares in the future; because distribution is deferred until termination, these awards do not provide immediate shares to sell. Such grants are routine and are informational rather than a direct trading signal.
