The filing shows: a grant/award of 503 shares and a grant/award of 257 shares (760 shares total) reported as derivative awards at $0.00, plus an exercise/conversion of 652 derivative units (acquired at $0.00) and a matching reported disposition of 652 derivative units (also $0.00). No cash proceeds or purchase prices are reported for these entries.

Key Details

• Transaction date: March 5, 2026; Form 4 filed March 9, 2026 (Form 4s are generally due within 2 business days of the transaction).
• Reported prices/value: all entries reported at $0.00 (derivative awards/conversions, no cash proceeds shown).
• Shares reported acquired via award: 503 + 257 = 760 shares (derivative awards).
• Derivative exercise/conversion: 652 units exercised/converted and 652 units reported disposed (both $0.00).
• Shares owned after the transactions: not specified in the filing.
• Notable footnotes: awards reflect vesting of previously reported awards (vesting scheduled 2025–2028); file includes previously reported deferred stock units; one set of stock units vests in full on March 5, 2027; some units reflect deferred cash fees notionally invested and payable in stock upon separation from board service.

Context
These entries look like administrative award vesting and conversions of deferred stock units rather than open-market buy/sell trades. Derivative entries (code M) indicate an exercise/conversion of rights into shares; the matching $0.00 disposition suggests an internal conversion/settlement or administrative transfer rather than a cash sale with proceeds. Because no cash amounts are shown, these entries do not represent a typical purchase (bullish) or sale (liquidation) signal for investors.
