Insights

Compensation & Governance Analyst

TL;DR: A routine equity compensation accrual: 132.183 RSUs granted as dividend equivalents, vesting tied to original awards; no cash price was paid.

The grant reflects the company's practice of crediting dividend equivalents as additional RSUs under the 2022 LTIP. Such accruals are common for executive compensation and serve to maintain the economic equivalence of equity awards over dividend periods. The award vests on the third anniversary of the original underlying RSUs, aligning with multi-year retention incentives. The Form 4 lists 124,686.639 shares beneficially owned after the grant and explicitly excludes 14,454 spouse-held shares from that count. This disclosure is standard and provides transparency on executive holdings and vesting schedules.

Corporate Governance Expert

TL;DR: Disclosure documents a non-cash issuance of RSUs tied to dividend equivalents; filing is informational and not materially transformative.

The filing documents a non-derivative grant under the 2022 LTIP recorded as a zero-price transaction, consistent with dividend-equivalent crediting. Vesting remains linked to original award timelines, reinforcing retention incentives. The report specifies the reporting person’s titles as President and CEO and Director, clarifying insider status for investors and regulators. No amendment or corrective language appears necessary, and the section 16 filing was made by one reporting person with a confirming signature dated 09/30/2025.
