Context
This is a standard equity compensation grant rather than a market purchase or sale; RSUs are typically used to retain executives and align their interests with shareholders. Because the units are restricted and subject to vesting, they can be forfeited if the reporting person leaves before the vest date and do not by themselves signal a buy or sell decision in the open market.
