Insights

Corporate Governance Analyst

Director received compensation shares and holds significant phantom units.

This transaction shows routine director compensation: 925 shares were acquired at $45.93 under the 2020 Incentive Compensation Plan, increasing direct beneficial ownership to 8,870 shares. Such grants align director pay with shareholder value because they are equity-based.

The report also records 44,166.6672 phantom stock units that vest or are paid after service ends under the Deferred Compensation Plan; these are economic equivalents to common shares and can affect long-term alignment and dilution dynamics when settled in shares.

Compensation Specialist

Compensation delivered via equity and phantom units; dividends are reinvested.

The filing clarifies that the 925 shares were paid quarterly as director compensation and that dividend reinvestments are included in the 8,870 share total. The phantom units include accrued dividends, indicating the plan preserves dividend economics until payout.

This structure—current equity plus deferred phantom units—combines immediate ownership with deferred pay tied to future service termination, consistent with common outside-director arrangements.
