Context

• This was a conversion/vesting of RSUs rather than an open-market purchase or sale. Such conversions are routine awards vesting rather than a directional insider purchase or cash sale; the filing does not show proceeds or an open-market trade. The derivative code "M" indicates exercise/conversion of a derivative instrument (here, RSUs converting to shares).
