Governance Assessment

  • Strengths

    • Independent Chair (Mills) provides robust separation of oversight and management; independent executive sessions each meeting .
    • Formal governance processes: annual Board and committee evaluations; rigorous independence screening; clear resignation policies (plurality-plus; age 72 retirement) .
    • No director-related party transactions in 2024; anti-hedging/anti-pledging policies enhance alignment .
    • Director compensation is balanced (cash + time-based RSUs) and in-line with peers; no meeting fees minimize pay inflation .
  • Potential Watch Items

    • Board tenure: Mills has served since 2011; while experience supports continuity, investors may monitor refreshment as he approaches age-based resignation threshold (72) .
    • Equity awards are time-based for directors (no performance linkage); alignment relies on ownership guidelines and anti-hedging rather than performance-conditioned director pay .
  • Alignment and Shareholder Signals

    • Say-on-pay (executive) support was 97% at 2024 meeting, signaling broader shareholder confidence in compensation governance overseen by the Board chaired by Mills .
    • Committee independence and use of independent consultants (Meridian) for executive compensation design bolster governance rigor .

RED FLAGS: None disclosed for Mills—no related-party transactions, no pledging/hedging, independent status affirmed, and engagement (attendance minimums) met .
