Insights

Corporate governance analyst

Routine RSU grant increases director’s deferred equity stake.

Director E. Mark Rajkowski was granted 32,809 Restricted Stock Units under ACCO BRANDS’ Incentive Plan. This is compensation-related equity, not an open-market purchase or sale, and reflects standard board remuneration in stock-linked form.

The RSUs are deferred under the Deferred Compensation Plan for Non-Employee Directors and settle in common shares upon death, disability, or board service cessation. This structure aligns director incentives with long-term shareholder outcomes, while the timing of any share delivery depends on future service and life events.
