Governance Assessment
- Strengths: Independent status affirmed despite legacy Skadden affiliation; active service on Risk and Compensation—committees central to risk oversight and pay governance; attendance at or above expectations; equity retainer with robust retention policy and anti‑hedging/anti‑pledging rules supports alignment .
- Potential watch items: Perceived optics of law firm affiliation (Board deemed non‑material); relatively small absolute share ownership typical for directors but mitigated by ongoing equity grants and strict retention policy; say‑on‑pay support dipped to 78% in 2024 (driven by macro TSR headwinds per BKU’s outreach) suggesting broader investor sensitivity to pay‑for‑performance—monitor Compensation Committee disclosures where Rubenstein serves .
- Conflicts: No related‑party transactions reported for 2024/YTD 2025; insider trading controls and executive sessions strengthen governance .
No Form 4 insider transaction details are disclosed in the proxy; BKU reports that all Section 16(a) filings required in 2024 were timely filed (for transaction‑level data, refer to SEC Form 4 filings) .
