Context
These awards are standard director compensation and vest over several years, so they do not represent an immediate open‑market purchase or sale. Because the grants vest gradually, the shares are not fully realizable immediately. Retail investors typically view routine director awards as compensation rather than a direct signal of immediate insider buying or selling.
