Closing Summary

Conclude every checklist with:

• Critical Findings — material risks requiring deal-team escalation
• Required Consents/​Approvals — third-party, regulatory, or lender consents to close
• Recommended Follow-Up — specialist engagement (environmental, benefits, IP)
• Open Items — documents requested but not yet received

Pitfalls

• Tailor scope to transaction type: asset purchases → assumed liabilities and excluded assets; investments → cap table, anti-dilution, governance rights
• Adjust materiality thresholds to deal size and industry
• Flag oral agreements — they create successor liability risk
• For cross-border targets, flag jurisdiction-specific requirements (foreign investment review, local labor law, non-US tax)
• Do not render legal opinions — flag issues for attorney review
• Verify all regulatory citations for applicable jurisdiction and year [VERIFY]
