Context These transactions are compensatory equity awards and the settlement of vested RSUs for a non-employee director, a routine form of director pay rather than an open-market purchase or sale. Derivative/“M” entries here reflect conversion/settlement of RSUs and related dividend equivalents into common shares (not a cashless market sale). Such awards are common and do not by themselves indicate the director buying or selling stock in the open market.
