Context

• This was a deferral/award of a cash incentive into common stock units (an internal plan conversion), not a market buy or sale. The units are vested but distribution is deferred until retirement per the schedule noted, so the transaction does not reflect an immediate market trade or change in circulating shares. The reported value is approximately $345k.
