Context
- These transactions consist of RSU vesting, a new RSU grant, and a deferral into deferred stock units — not open-market buying or selling. RSU grants and deferrals are common compensation actions and do not by themselves indicate a buying or selling decision in the market.
- Deferred stock units are treated as a form of delayed compensation and convert to common shares only upon the specified payout events.
