Positive

• Director participation in deferred compensation plans aligns his pay with shareholder value via share‑equivalent units
• Voluntary deferral (1,178 units) shows director choosing future‑linked compensation rather than immediate cash

Negative

• Deferred units create a future cash obligation for the company payable upon termination of service
• Filing does not disclose exact payout timing or plan termination triggers, leaving timing of cash outflow unclear

Insights

Corporate Governance Analyst

Director deferred compensation increased his stake in share-equivalents by 1,665 units.

The reported transactionsAre credits of phantom stock units under the Directors' Deferred Compensation Plan rather than open-market purchases; each unit mirrors one share's value and is payable in cash after termination of service. The filing shows a voluntary deferral of 1,178 units at an indicated reference price of $62.35 and an automatic deferral of 487 units.

These entries raise direct beneficial ownership to 53,576 share-equivalents, including 1,130 units credited as dividend reinvestment since 5/01/2025. Monitor future Form 4s for any cash payouts or exercises tied to departure timing.

Compensation & Benefits Specialist

Deferrals reflect standard director compensation choices, increasing deferred cash liabilities.

Phantom stock units are a cash‑settled vehicle that shifts compensation from immediate cash to future cash tied to share value; the plan references hypothetical reinvestment of dividends which boosted the unit count by 1,130 since 5/01/2025. These credits do not dilute equity but increase the company's deferred compensation obligation.

Investors tracking future cash outflows should note the total units credited (1,665 on 10/07/2025) and the aggregate direct beneficial ownership reported as 53,576 units; timing of payouts depends on director service termination rules in the plan.
