# Skill: Compare Merger Filing Requirements Across Multiple Jurisdictions

## 1. Subject-matter triage
- Treat the matter as a filing-and-timing comparison across all jurisdictions implicated by the deal materials and revenue data.
- First identify every potentially relevant jurisdiction from the record, then confirm which ones are actually in scope for filing analysis based on nexus, turnover, assets, transaction value, or similar tests.
- If the facts support only one jurisdiction, say so explicitly and explain why the others are out of scope.

## 2. Failure modes the skill is correcting
- Reaching filing conclusions without showing how the parties’ relevant metrics are measured against each jurisdiction’s threshold test.
- Collapsing distinct jurisdictional regimes into one generic merger-control summary, which obscures filing posture, timing, and review risk.
- Omitting the governing authority, statutory or regulatory basis, and filing-fee or administrative cost considerations needed for a practice-ready memo.
- Failing to distinguish jurisdictional filing obligation from substantive competition risk where overlaps, concentration, or sector sensitivity may lengthen review or drive remedies.
- Presenting conclusions without tying each legal proposition to the controlling authority or rule that supports it.
- Skipping the action-oriented close of the memo, leaving the reader without next steps, owners, or timing anchors.

## 3. Legal frameworks / domain conventions that apply
- Merger-control analysis is jurisdiction-specific: thresholds may be turnover-based, asset-based, transaction-value-based, or a combination, and often include a local nexus element.
- Many regimes impose pre-closing notification and a suspensory waiting period; some provide phase extensions, information stops, or conditional clearance paths that alter the timeline.
- Separate filings may be required in multiple jurisdictions unless a true one-stop-shop or exclusive competence mechanism applies under the relevant regime.
- Where overlapping products or services exist, assess market definition, combined shares, concentration, and sector sensitivity to gauge review intensity, remedy risk, and the likelihood of deeper investigation.
- Pre-filing consultation, informal engagement, or notification planning can be part of the practical filing strategy where uncertainty, sensitivity, or timing pressure exists.
- Each legal proposition should be supported by the controlling statute, regulation, agency rule, or other recognized authority applicable to that jurisdiction.

## 4. Analytical scaffolds
For each relevant jurisdiction:
1. Identify the governing competition authority and the controlling filing regime.
2. State the threshold structure and the legal source for each threshold component.
3. Compare the deal facts to each threshold component using the numbers in the record; if a calculation is required, show the comparison in a compact form without inventing missing inputs.
4. State the resulting filing posture: mandatory filing, voluntary filing, no filing, or further factual review needed.
5. Identify timing mechanics: waiting period, suspension, phase review, extension triggers, and any stop-the-clock or pre-notification steps.
6. Note filing-fee or administrative cost items if they apply.
7. Assess substantive competition issues: overlaps, horizontal or vertical concerns, concentration, sector sensitivity, and likely remedy or information-request risk.
8. Identify any cross-border coordination issue, including whether multiple filings proceed in parallel or sequence.

Cross-cutting analysis:
- Enumerate the jurisdictions first, then analyze each jurisdiction on the same dimensions so the comparison is complete and parallel.
- Compare filing burdens, timing, and sensitivity to identify the critical path jurisdiction or jurisdictions that are likely to control closing timing.
- Flag where a jurisdiction is likely to require the deepest competition analysis or the strongest remedy planning.
- If a threshold or nexus test cannot be completed from the available facts, identify the missing data point and avoid overclaiming.

## 5. Vertical / structural / temporal relationships
- Organize the memo from global summary to jurisdiction-specific detail, then return to a cross-jurisdiction timeline and risk synthesis.
- Within each jurisdiction, move in the order: authority, legal basis, threshold analysis, filing posture, timing, fees, substantive review issues, and recommended next steps.
- Where multiple parties, territories, or product lines matter, separate them before analysis and keep the jurisdictional comparison aligned to the same factual set.
- Tie each jurisdiction’s review mechanics to the transaction timetable, noting which authority can delay signing, closing, or integration most materially.

## 6. Output structure conventions
- Prepare a practice-ready jurisdictional comparison memo organized by jurisdiction with a concise executive overview up front.
- Include a comparison table summarizing, for each jurisdiction: authority, filing basis, threshold result, filing posture, timing mechanics, fees, and principal review issues.
- For each jurisdiction section, use industry-conventional headings rather than a rubric-like checklist; include the legal source, threshold analysis, filing implication, timing, substantive concerns, and practical recommendation.
- Where legal conclusions are stated, cite the controlling authority by name and section, regulation, article, or recognized rule.
- End with a clear Recommended Actions section that assigns each action to a role and ties it to a filing or closing milestone.
- Keep the analysis memo-ready: concise, comparative, and directly usable for deal execution.
