Insights

Corporate Governance Expert

Director received dividend-equivalent rights on RSUs; ownership updated to reflect accruals.

The Form 4 reports a non‑cash acquisition of 1,145.5 dividend-equivalent rights on 09/30/2025, tied to existing restricted stock units. This is an administrative equity compensation adjustment triggered by the board's declared dividend of $0.15 per share.

The filing shows 143,745 shares beneficially owned following the accrual, recorded as direct ownership. Board approval under Rule 16b-3 indicates the action followed the safe-harbor framework for insider awards and waives no disclosure requirement.

Executive Compensation Specialist

Dividend-equivalent rights credited on RSUs instead of cash payout.

The explanatory note states each dividend equivalent right entitles the holder to one share upon RSU settlement and is subject to the same vesting and settlement conditions as the Original RSUs. The reported transaction code and zero price ($0) confirm these are dividend accruals, not open-market purchases.

Because these rights mirror RSU terms, the practical effect is a future share issuance tied to vesting rather than immediate cash, preserving the original RSU alignment with long-term incentive goals.

Explanation of Responses:

1. On July 23, 2025, the Issuer announced that its board of directors declared a quarterly cash dividend in the amount of $0.15 per share of its common stock, payable on September 30, 2025 to stockholders of record of the common stock at the close of business on September 15, 2025 (the "Dividend"). The amount acquired in column 4 represents equivalent rights accrued as a result of the Dividend on restricted stock units with respect to the Issuer's common stock ("Original RSUs") held by the reporting person. Each dividend equivalent right entitles the reporting person to receive one share of the Issuer's common stock upon the settlement of the Original RSUs and is subject to the same terms and conditions, including vesting and settlement, as the Original RSUs to which it relates. The grant of dividend equivalent rights was approved by the Issuer's board of directors pursuant to Rule 16b-3 of the Securities Exchange Act of 1934, as amended.
