Context
Restricted stock units for directors are routine compensation and represent a deferred/derivative interest that becomes common stock only if and when vesting conditions are met and conversion occurs. This grant does not indicate an immediate open-market purchase or sale and should be viewed as part of standard director pay rather than a direct trading signal.
