Context
RSU grants are awards that convert to shares upon vesting; they are not purchases or sales. The May 11 grant vested immediately, providing an immediate right to shares, while the May 12 grant is multi-year and will vest over time (so only a portion becomes actual shares each year unless accelerated by the award terms). These filings are informational about insider compensation and do not by themselves indicate the director is buying or selling stock in the open market.
