Insights

Corporate Governance Specialist

Director deferred compensation increased his cash‑payable phantom holdings by 487 units.

The transaction reflects an automatic deferral of director retainer fees into the Directors' Deferred Compensation Plan, creating 487 phantom stock units on 10/07/2025. These units mirror the market value of common stock but are settled in cash after service ends, so they do not immediately change voting power.

The main dependency is the plan's cash‑settlement feature: these units create future cash exposure tied to share price and dividend reinvestment, evidenced by 395 dividend-equivalent units credited since 04/07/2025. Monitor annual retainer deferral elections and any future exercises or payouts for timing of cash obligations within a 1–5 year horizon.
