Insights

Securities Analyst

TL;DR: Insider modestly increased holdings via dividend reinvestment and made a small gift, net change minimal relative to total holdings.

These Form 4 entries show routine equity activity by a senior executive: two dividend-reinvestment acquisitions totaling 93.914 shares on 08/15/2025 and a 2,182-share gift transfer on 08/29/2025. The purchases were executed under the company DRIP and reported under Rule 16a-11, which is a common, non-discretionary method of increasing share ownership. The gift is reported as exempt under Rule 16b-5. Post-transaction direct beneficial ownership remains around 404,057 shares, indicating no material change to insider stake.

Corporate Governance Expert

TL;DR: Transactions are routine, properly disclosed, and use standard exemptions for DRIP and gift transfers.

The filing documents compliant Section 16 reporting by the President and CIO. Use of Rule 16a-11 for dividend reinvestment and Rule 16b-5 for a gift transfer are standard. Signature by an attorney-in-fact is noted and dated 09/02/2025. There are no derivative transactions reported and ownership remains direct.
