Context

RSUs are a form of compensation that convert to common shares only upon vesting; they require no cash outlay at grant and do not represent immediately tradable shares. Because Rothberg is a 10% owner and the grant was made under the company's non-employee director compensation policy, this is a routine director award rather than an open-market trade by an executive.
