Context
This was a compensation-related equity grant to a board director (typical director retainer), not an open-market purchase or sale. Awards at $0 price are standard for equity compensation and do not by themselves indicate the director is buying or selling based on private information. The inclusion of dividend-reinvested shares simply corrects prior reporting and is administrative in nature.
