- Target — company name, incorporation/operation jurisdictions
- Timeline — anticipated closing date
- Scope — business units, subsidiaries, time periods, materiality thresholds
- Priorities — known concerns, industry-specific risks, regulatory focus
Output each line item as: Item | Documents Requested | Received (Y/N/Partial) | Issues/Notes

- Tax returns (federal, state, local, foreign); audits, assessments, open examinations
- AR/AP aging, debt schedule with covenant compliance, off-balance-sheet obligations
- Revenue recognition policies, related-party transactions, restatements
Red flags: Covenant defaults, audit qualifications, restatements, contingent liabilities, aggressive revenue recognition.

5. Litigation & Regulatory
- Pending lawsuits, arbitrations, mediations (status + exposure)
- Demand letters, cease-and-desist, threatened claims
- Agency investigations, consent decrees, administrative proceedings
- Settlement agreements, ongoing monitoring obligations
- Operating licenses/permits (expiration, violations)
- Regulatory compliance: antitrust, export controls, FCPA/UK Bribery Act
- Data privacy: GDPR, CCPA, HIPAA — policies, breach history, DPAs
- Whistleblower complaints, internal investigations
Red flags: Unquantified exposure, systemic compliance failures, successor liability risk, required regulatory approvals for closing.
6. Employment, Labor & Benefits
- Employee census: headcount by role, compensation, location, status (EE/contractor/PT)
- Key employee agreements, offer letters, severance, equity grants
- Non-competes, non-solicits, confidentiality agreements
- Employee handbook, leave policies (FMLA, state leave)

- ESG: carbon/sustainability commitments, climate risk disclosures
Red flags: CERCLA/Superfund exposure, ongoing remediation, unresolved NOVs, ESG obligations creating future compliance burdens.
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]
