Context

These awards are part of executive compensation (grants/RSUs) and are not purchases or sales; they typically vest later and are not an immediate cash investment by the insider.
RSUs that vest in the future may convert to company stock at vesting; dividend equivalents and performance-vesting language can affect final payout amounts.
