Insights

Securities Analyst

TL;DR: A small director purchase of 25 shares was recorded, increasing direct beneficial ownership to 32,591.0194 shares.

The Form 4 documents a routine insider acquisition rather than a large, material transaction. The purchase price of $33.13 and the small quantity (25 shares) suggest this was not a substantial capital commitment. The filing notes that the overall share total includes dividend reinvestment, indicating ongoing accumulation through company distributions. For investors, the data is factual disclosure of insider activity that maintains transparency.

Corporate Governance Expert

TL;DR: Director-level disclosure complies with Section 16 reporting; transaction appears routine and properly reported.

The Form 4 shows the reporting person is a director and filed as an individual reporting person. The document includes a clear transaction code for an acquisition and a signature by power of attorney, which are standard in timely insider reporting. There are no indications of amendments or unusual derivative activity in this filing.
