Context

RSUs are compensation that convert to shares only upon vesting and do not represent an immediate purchase or sale of stock. This award appears to be a standard director retention/compensation grant with a relatively short, monthly vesting schedule; it should not be interpreted on its own as a signal of the director’s view of the company.
