Active committee participation (Audit, Governance) aligns with risk oversight and governance best practices; strong attendance benchmarks support engagement .
  • Alignment & incentives: Mandatory DSU deferral (≥60% of retainer) and post-service payout enhance long-term alignment; prohibition on selling GM securities during service and no pledged shares reduce misalignment risks .
  • Conflicts & interlocks: No other public boards and no disclosed related-party transactions/interlocks for Tatum reduce network conflict risks; Governance Committee retains oversight of related-party matters .
  • Compensation structure signals: Year-over-year total compensation decreased modestly (2023 $376,619 → 2024 $370,761), with DSU grant fair value lower in 2024 due to pricing mechanics (closing price $53.27 vs $35.92 base year methodology differences). Perquisites increased, driven by Company Vehicle Program usage—an optics consideration but standard under GM’s director program .
  • RED FLAGS: None disclosed specific to Tatum. No pledging; no related-party transactions; attendance meets thresholds; independence maintained .
