Insights

Corporate Governance Analyst

Director accrued 196.572 cash‑settled phantom units under deferred plan

This Form 4 records a routine director compensation accrual rather than an open‑market trade: 196.572 phantom stock units were credited on 10/01/2025 under the company’s deferred compensation plan for non‑employee directors.

The units are cash‑settled at termination, meaning they are economic equivalents of shares but will not increase outstanding share count if paid in cash; the filing also reports 22,617.816 beneficially owned share equivalents after the accrual.
