# Antitrust Investigation Summary

Decision-ready antitrust investigation brief with evidence-linked chronology, legal theories, and business risk assessment.

## Quick Start

Gather before drafting:
- Regulatory process documents (CIDs, subpoenas, Second Requests, notices)
- Internal investigation materials (interview memos, forensic reviews, privilege logs)
- Market data (shares, competitors, pricing, entry barriers)
- Public sources (press, filings, complaints, consent decrees)
- Current status (deadlines, productions, negotiations)

## Workflow

### 1. Build Key-Facts Table

Populate and resolve gaps before drafting.

| Field | Detail |
|---|---|
| Investigating Authority | Agency, division, lead office, contact(s) |
| Matter Type | Conduct, merger, or industry sweep |
| Alleged Conduct | Price-fixing, monopolization, exclusive dealing, etc. |
| Market Definition | Product and geographic market as asserted |
| Statutory Hooks | Sherman §1/§2, Clayton §7, FTC Act §5, state/foreign provisions |
| Initiation Trigger | Complaint, market study, HSR, dawn raid, etc. |
| First Notice Date | Date and instrument |
| Procedural Posture | Inquiry, formal investigation, litigation, appeal |
| Key Deadlines | Production dates, meetings, milestones |
| Exposure Signals | Penalties, remedies sought, damages claims |
| Remediation | Compliance changes, business changes |

### 2. Draft Summary

Use this template. Cite every factual assertion with `[source: <id>]`.

### 3. Multi-Jurisdiction Matters

If multiple authorities are involved, create one subsection per authority and a consolidated risk section.

## Pitfalls

- **Allegations vs. facts**: Separate clearly; never speculate.
- **Missing data**: Flag with `[VERIFY]`, especially for uncertain statutes or foreign-law citations.
- **Exact references**: Use precise dates, agency names, and instrument titles — do not paraphrase.
- **Inferences**: Label explicitly and cite the underlying source.
- **Merger matters**: State the asserted theory of harm and any divestiture or behavioral remedy signals.
- **Parallel proceedings**: Include state AGs, EC, CMA, or other competition authorities as separate subsections.
- **Privilege headers**: Maintain `ATTORNEY-CLIENT PRIVILEGED & WORK PRODUCT` on every output.
