Context These grants are compensation awards to a non-employee director rather than open-market purchases or sales; they do not by themselves indicate a change in the director’s market view. DSUs defer settlement (often for tax or governance reasons) and convert to shares upon satisfying vesting and the Program’s settlement conditions. The Form 4 was filed the day after the grants, which is within the standard two-business-day reporting window for insider transactions.
