Context

The RSUs represent the contingent right to receive common shares upon vesting; the 120,000-share entry is a stock option award (not an exercise). Neither award involved an open-market purchase or sale, nor were shares sold or exercised at grant. These are compensation grants subject to service-based vesting.
