Responding to a Cartel Investigation: A Practical Guide

Document type: Guide Practice area: Corporate — Antitrust Jurisdiction: United States (federal) Last reviewed: 5 September 2026

Who this is for

The general counsel who has just learned something alarming, and the lawyer they call.

Our example is Marchgate Polymers, a $700 million specialty chemicals producer with three significant competitors in one product line. Its general counsel is Teodora Vasilenko-Achebe.

The organizing fact: leniency goes to the first company to report, and there is one spot. Everything in this guide is shaped by that, including the uncomfortable instruction in Step 3 to make the most consequential decision of the matter on incomplete information.

Step 1 — Recognize how it starts

The unannounced approach. Agents appear at an employee's home in the evening and ask to talk. No warnings are required in a non-custodial setting, the employee may not be told who the target is, and no lawyer is present. This is the Division's most effective technique.

The search warrant. Agents arrive at the office, seize servers and devices, and interview whoever is there. What happens in the first hour shapes the matter.

The grand jury subpoena, for documents or testimony, served on the company or on individuals.

The competitor's call. Opposing counsel telephones to say their client has applied for leniency. The race is already over.

Or an internal discovery — a compliance audit, a departing employee, a document in unrelated litigation, or acquisition diligence. Marchgate's came from an expense audit that flagged a pattern of dinners with competitor counterparts.

In every case, the first forty-eight hours are disproportionately important, because they determine whether evidence is preserved, whether employees say things that cannot be unsaid, and whether the company is first.

Step 2 — The first forty-eight hours

Engage criminal antitrust counsel the same day. Not the company's regular corporate firm unless it has this practice. The judgments required — marker or not, how to approach employees, whether to cooperate — are made by people who have made them before.

Issue the litigation hold immediately, covering email, chat and messaging platforms, shared drives, calendars, expense and travel records, phone records, and personal devices used for work. Suspend every deletion rule and confirm implementation in writing with IT, system by system.

Instruct affirmatively that nothing is to be destroyed, and document delivering that instruction. Obstruction under 18 U.S.C. § 1512 has produced longer sentences than the underlying offense in more than one matter, and the impulse to tidy is strongest in exactly the people who know what is in the files.

Brief employees on their rights, neutrally. They may speak with agents or decline. They may have counsel present. They must not lie — 18 U.S.C. § 1001 makes a false statement to a federal agent a separate felony and it is charged. The company will provide counsel. Deliver this as information, not instruction, because telling employees not to cooperate looks like obstruction.

If a search is underway: counsel to the site immediately; obtain and read the warrant; record what is seized; do not consent to anything beyond the warrant's scope; assert privilege over privileged materials and log the assertion; do not obstruct; send non-essential employees home; and instruct that no one discusses the search externally.

Then go straight to Step 3. Do not spend a week getting comfortable.

Step 3 — Decide about a marker, on incomplete facts

This is the hardest professional judgment in the matter and the one that determines its cost.

Ask four questions:

Is there conduct that could be a per se offense? Not "did we violate the Sherman Act" — is there evidence of communication with competitors about price, bids, customers, territories, or wages? A pattern of contacts plus a suggestive correlation is enough to ask.

Are we plausibly first? What might have prompted a competitor to report — a change of ownership or general counsel, a departing executive, an unrelated investigation? If any competitor has recently had one, assume the clock is running.

What is the exposure if we are second? A fine under 18 U.S.C. § 3571(d) calculated as twice the gross gain or loss; treble damages under 15 U.S.C. § 15 with joint and several liability and no contribution after Texas Industries, Inc. v. Radcliff Materials, Inc., 451 U.S. 630 (1981); parallel state indirect purchaser claims; foreign fines and damages; and individual prosecutions.

Can we qualify? Were we the leader or originator? Did we coerce anyone? Can we terminate promptly? Can this be a corporate confession rather than individual ones?

Then seek the marker. It holds the company's place in line for a limited period while counsel completes the investigation needed for a full proffer. It can be sought on very little.

Frame it correctly for the board. A marker preserves an option; it is not an admission and it can be withdrawn. Framed that way, it is a decision a board can make in a day — which is what the situation requires.

Marchgate sought its marker on day three, knowing only that a vice president had attended six undocumented dinners with competitors whose timing correlated with price announcements.

Step 4 — Coordinate globally, the same week

Cartels are rarely national, and this is the step companies most often perform late.

Every relevant jurisdiction has its own leniency program, its own queue, and its own conditions. United States leniency confers nothing elsewhere.

Engage local counsel in the affected jurisdictions within days, not weeks, and file parallel applications. The European Union, the United Kingdom, Canada, Japan, Korea, Brazil, and others each require their own filing.

Watch the sequencing constraints. Some regimes have their own marker systems; some require specific content; some are affected by what is disclosed elsewhere. A company that secures a United States marker and applies in Europe three weeks later has typically lost Europe.

Coordinate the substance. The account given to each authority should be consistent, because authorities cooperate and compare. Inconsistency is worse than a late filing.

And map the civil consequences too. Follow-on damages litigation is now substantial in several jurisdictions, with its own disclosure rules — some of which protect leniency materials and some of which do not.

Step 5 — Run the internal investigation, with the conflicts managed

Scope it in writing, at counsel's direction, in anticipation of litigation: conduct, period, systems, custodians, and who authorized it.

Retain separate counsel for individuals, early. Everyone who may have participated needs their own lawyer, funded by the company where charter, bylaws, and law permit. Providing counsel is not obstruction; interviewing exposed people under a company banner without it is a real problem.

Give Upjohn warnings in every interview and document them: the lawyer represents the company, not the individual; the privilege belongs to the company; the company may waive it and disclose what is said, including to the government.

Stop when exposure diverges. The moment an individual's interests separate from the company's — they made the decisions, they were in the room, they may be a target — say so and refer them to their own counsel.

Investigate what the government will investigate: competitor contacts of every kind, calendars, travel and expense records, phone records, trade association participation, benchmarking programs, and the correlation between contacts and pricing or bidding decisions.

Watch the format of the record. Attorney memoranda reflecting mental impressions are core work product; verbatim transcripts and recordings are far less protected and are a discovery target.

Do not create a findings document until the conclusions are settled, and plan the waiver question in advance — cooperation credit generally requires providing information about individuals, which is a board-level decision that reallocates risk onto the company's own people.

And terminate the conduct. Leniency requires prompt and effective termination, and doing it properly — with a documented instruction, a communication to the relevant employees, and a record — is itself evidence.

Step 6 — Handle joint defense arrangements carefully

They are common, useful, and constraining. A joint defense agreement permits coordinated strategy and privileged information sharing among parties with common interests, and in a multi-defendant cartel matter it is often how defense counsel operate.

The problem is that interests diverge. A company that joins a group and later decides to cooperate must extract itself, and the information it received under the agreement complicates that. Some agreements purport to restrict a member's later use of shared information; some require notice before withdrawal.

So: enter in writing, with an express exit provision, a clear statement that each party may withdraw and pursue its own interests including cooperation, and a defined treatment of previously shared material.

Do not join before deciding about leniency. A company still assessing whether to seek a marker should not be sitting in a defense group with the companies it may report.

Assume the government is interested. Prosecutors view joint defense arrangements in cartel matters with attention, and participation is sometimes characterized as evidence of continued alignment.

And keep the individuals' counsel separate from it. An executive facing prison has different interests from the company funding their lawyer, and a joint defense structure that blurs that is a conflict waiting to be raised.

Step 7 — Cooperate, or negotiate a plea

If you have leniency, cooperation is the price and it is substantial: full document production, witnesses made available for interviews and grand jury testimony, and assistance in the prosecution of competitors and — frequently — of former colleagues. It runs for years and it is a condition, not a courtesy. Assign an owner and budget for it.

If you do not, negotiate the plea. The terms that matter:

The charged conduct and its period, which sets the boundaries of everything else.

The volume of affected commerce — the base of the sentencing calculation and the anchor of the civil damages claim. Negotiate this hardest. A definition that sweeps in sales outside the conspiracy's product scope, geography, or period costs twice: once in the fine and again in the civil case.

The fine, calculated under the Guidelines' antitrust provisions on that volume with a culpability multiplier, and subject to the alternative fines provision of 18 U.S.C. § 3571(d). Payment schedule and ability-to-pay considerations belong here.

Cooperation obligations, and what credit they earn.

Treatment of individuals — who is covered and who is carved out for prosecution. A plea that resolves the company and carves out named executives is sometimes unavoidable and is always a conscious decision.

And the factual admissions, which become prima facie evidence in the civil litigation under 15 U.S.C. § 16(a). Draft them with civil counsel in the room.

Step 8 — Prepare for the follow-on civil litigation before it is filed

It will be filed within days of the first public charge, and it will usually cost more than the fine.

The exposure: treble damages under 15 U.S.C. § 15; joint and several liability for the entire conspiracy's damages with no contribution after Texas Industries; federal direct-purchaser classes under Illinois Brick Co. v. Illinois, 431 U.S. 720 (1977) with no pass-on defense after Hanover Shoe, Inc. v. United Shoe Machinery Corp., 392 U.S. 481 (1968); parallel state indirect purchaser actions; opt-out actions by large customers; and broad venue under 15 U.S.C. § 22.

Pleading is not much of an obstacle after a plea. Bell Atlantic Corp. v. Twombly, 550 U.S. 544 (2007) requires facts suggesting an agreement, and the plea supplies them.

If you have leniency, pursue ACPERA. A successful applicant that provides satisfactory cooperation to civil claimants is liable only for single damages attributable to its own conduct, rather than treble damages with joint and several liability.

What that requires: timely and satisfactory cooperation with the plaintiffs — a full account of the facts, document production, and witnesses made available to the people suing you. The court decides whether it was satisfactory, often late.

Do it deliberately and document it. Designate the cooperation, log every production and interview, and be able to show the court a record. The benefit is frequently an order of magnitude, and it is lost by informal or grudging cooperation nobody tracked.

And coordinate the criminal and civil defense. Statements in one are used in the other, and a stay of the civil case pending the criminal resolution is worth seeking.

Step 9 — Manage the collateral consequences

Suspension and debarment, if the company sells to government purchasers. Suspension can be immediate and does not require a conviction; debarment can run years and reach affiliates. It is administered by suspension and debarment officials — a different part of the government, on a different timeline — and it is resolved through an administrative agreement negotiated in parallel with the criminal resolution. A plea agreed without one can leave a company criminally resolved and commercially finished.

Program exclusion and licensing consequences in regulated industries.

Foreign consequences, including fines, debarment from public procurement, and follow-on damages in several jurisdictions.

Disclosure and reserves for a public company: whether the loss is probable and estimable, what must be said and when, and the interaction with a sealed or ongoing investigation. Involve auditors and disclosure counsel early.

Insurance. Notify every carrier that might respond. Understand that fines and penalties are typically uninsurable and that defense costs may be covered — and that the coverage analysis differs sharply between the criminal matter, the civil class actions, and any derivative suit.

Derivative and securities litigation, which frequently follows a substantial antitrust resolution.

And the people. Executives will be prosecuted, resign, or be terminated. Employment decisions taken during an investigation are scrutinized, so make them on documented grounds and with counsel.

Step 10 — Remediate, visibly

Remediation matters to the sentencing calculation, to the resolution's terms, and to whether the company is in this position again.

Terminate and document. The conduct, the personnel decisions, and the controls changed.

Train the people who actually talk to competitors — sales, procurement, estimating, and executives in trade association roles. Short, concrete, industry-specific, with real examples. Not a general module.

Fix the trade association exposure. Agendas reviewed in advance, counsel available, a written rule that no discussion of price, cost, capacity, customers, or bidding occurs, and a documented obligation to leave and report if one begins.

Audit the information exchange programs. Aggregated, historical, independently administered benchmarking is generally lawful; current, disaggregated, company-identified exchange is not, and many long-running industry programs sit closer to the second than participants believe.

Screen the labor-market agreements — no-poach and wage-fixing arrangements among employers have been prosecuted criminally and are frequently made by human resources without antitrust involvement.

Build a reporting channel people use, and respond to what arrives.

And shorten the escalation path. The most valuable structural feature a compliance program can have in this area is that a general counsel who learns something alarming on Tuesday reaches experienced counsel on Tuesday — because in a race with one winner, days decide it.

Step 3A — When the answer is that there is no cartel

Not every alarming pattern is a conspiracy, and counsel who treats every competitor contact as a leniency question does the client no favors.

Test the alternative explanations. Parallel pricing in a concentrated market with transparent prices and homogeneous products is expected, not suspicious. A supplier and a customer discussing price is a vertical relationship, not a horizontal one. Meetings with competitors on standards, safety, regulatory advocacy, or a legitimate joint venture are ordinary and lawful.

Ask what was actually said. The distinction between market intelligence and agreement is whether there was an exchange of assurances. An executive who heard a competitor complain about margins at a conference has heard nothing actionable; one who responded "we're planning to move in September too" has.

Look at the timing correlation carefully. Price announcements that follow an industry conference may follow the conference because everyone attends and everyone reads the same data — or because of what happened at the dinner. The correlation raises the question; it does not answer it.

Check whether the conduct is per se at all. Information exchange, joint purchasing, standard setting, and genuine joint ventures are analyzed under the rule of reason. American Needle, Inc. v. National Football League, 560 U.S. 183 (2010) addresses when entities are capable of concerted action at all, and Leegin Creative Leather Products, Inc. v. PSKS, Inc., 551 U.S. 877 (2007) confirms rule of reason treatment for vertical restraints. Criminal enforcement is reserved for the per se categories.

But do not talk yourself out of it. The failure mode in both directions is real: companies that panic over lawful conduct waste money, and companies that rationalize a genuine cartel lose the race. The discipline is to answer a narrow factual question — was there an exchange of assurances with a competitor about price, bids, customers, territories, or wages — and to answer it with evidence rather than with the executive's characterization.

And where the answer is genuinely unclear, seek the marker anyway. It preserves an option, costs comparatively little, and can be withdrawn. The asymmetry of outcomes makes that the right call under uncertainty.

Step 4A — What the leniency conditions actually require

Counsel should walk the client through each condition before the marker, because failing one later forfeits everything.

First in. The applicant must be the first to report the activity. A marker holds the position while the investigation completes; it does not create it.

Prompt and effective termination. The conduct must stop, and stop properly — a documented instruction, communication to the relevant employees, and a record. Continuing participation "to avoid tipping off the others" forfeits leniency, however tactically appealing it sounds.

Candid and complete reporting. A partial account — omitting a product line, a period, or a participant — is the most common way applicants lose leniency, and the omission is usually discovered when a competitor's cooperation contradicts it.

Full, continuing, and complete cooperation. For years. Documents, witnesses, grand jury testimony, and assistance in prosecuting others. A company that becomes uncooperative in year three can lose the benefit earned in year one.

A corporate act. The confession must be the company's, authorized at an appropriate level — not isolated confessions by individuals who happen to be talking to the government.

Restitution where possible. To injured parties, where feasible.

Not the leader or originator, and no coercion. A company that instigated the cartel or forced others to participate does not qualify. This is worth assessing honestly at the outset, because the government will assess it later with the benefit of everyone else's account.

And the individual coverage question. Cooperating current directors, officers, and employees are typically protected — but people who have left the company are frequently not, and neither are those who refuse to cooperate. Identify early who is covered and who is not, because that determines who needs separate counsel with a very different message.

Step 5B — Preserving evidence properly

The hold in Step 2 is the single most consequential operational act in the matter, and holds in cartel cases fail in predictable ways.

Collect the sources cartel investigations actually care about, which are not the ones a commercial dispute cares about:

Calendars, which reveal meetings that appear nowhere else.
Expense and travel records, which reveal dinners, conferences, and who was in which city.
Phone records, including mobile — the call to a competitor rarely appears in email.
Chat and messaging platforms, including personal messaging used for work, where the frank conversation happens.
Trade association materials: agendas, attendee lists, minutes, and the informal materials circulated around meetings.
Benchmarking and statistical program submissions and outputs.
Bid files, including drafts, internal approval records, and any communication about a competitor's expected bid.

Then verify implementation, system by system, in writing. A hold that was announced but not technically applied is worse than none, because it documents that the company knew and did nothing. The recurring failure is a messaging platform with a short default retention that nobody in legal knew existed.

Reach departed employees' accounts and devices before routine decommissioning destroys them, and suspend device-wipe-on-departure.

Do not forget backups and legacy systems covering the conspiracy period, which may be the only place the early evidence survives.

Re-issue reminders and take re-acknowledgments quarterly. A four-year matter outlasts everyone's attention.

And document the affirmative no-destruction instruction, including who delivered it, to whom, and when. In a matter where obstruction charges are a live risk, that record protects the company and the people who received it.

Step 6A — The budget and the board

A cartel matter is one of the largest legal expenditures a company will make, and it runs for years. Frame it correctly at the first board briefing.

The phases and their costs. The internal investigation, front-loaded and intense. Separate counsel for individuals — a per-person cost that multiplies faster than anyone expects. Document collection, review, and production, which in a matter with a multi-year period and a dozen custodians is a substantial e-discovery project. Foreign counsel in every jurisdiction where an application was filed. Grand jury preparation and testimony. Then the civil defense, which in a multi-district class action with parallel state cases runs for years after the criminal matter resolves.

Present the exposure model beside it. With leniency and satisfactory ACPERA cooperation: single damages on your own sales, plus the cost of cooperation. Without: a fine under 18 U.S.C. § 3571(d) on the volume of affected commerce, treble damages with joint and several liability and no contribution after Texas Industries, state indirect purchaser exposure, foreign fines and damages, and individual prosecutions. The gap is usually an order of magnitude, and it is what justifies the spend.

Explain the timeline honestly: three to five years for the criminal matter, longer for the civil. The board will ask when it ends more than once.

Set the decision points in advance. The marker. The scope of cooperation. Whether to designate ACPERA cooperation and how far to go. Any plea and its factual admissions. Personnel decisions about implicated executives. Each is a board-level judgment, and a board that sees them coming decides better.

Report on a fixed cadence — monthly, one page: status, what the government has asked, what we have produced, what has changed in the assessment, and what decision is next.

And be candid when the picture worsens. Counsel who maintains an optimistic view through month eight and then arrives with a plea recommendation does more damage to the relationship than the plea does to the company.

Step 7A — Surviving a dawn raid

If agents arrive with a warrant, the first hour is managed by whoever is at the door. Prepare that hour in advance.

Have a written protocol, and train reception. The receptionist who greets federal agents should know exactly what to do: notify a named list immediately, ask the agents to wait in a designated room, and say nothing else.

Counsel to the site immediately, in person if possible and on the phone until then. Ask the agents to wait for counsel; they need not, but they frequently will briefly.

Obtain and read the warrant. What premises, what items, what date range. Note the issuing court and the agent in charge. The warrant defines the scope, and the company should not consent to anything beyond it — consent expands the search and cannot be withdrawn.

Shadow the search. Assign employees to accompany each agent team, taking contemporaneous notes of what is searched and what is taken. Request an inventory. Photograph or record where permitted.

Assert privilege, and log it. Identify privileged materials, state the assertion clearly, and ask that they be segregated. Do not physically interfere, and do not remove anything.

Do not obstruct, and say so out loud. No deletion, no removal, no shredding, no "let me just grab that file." Obstruction under 18 U.S.C. § 1512 is the charge that turns a manageable matter into a catastrophic one, and it is committed in the first hour by people acting on instinct.

Send non-essential employees home, and tell those who remain that they may decline to be interviewed, may have counsel, and must not lie — 18 U.S.C. § 1001 is a separate felony.

Capture the interviews that happen. Note who was interviewed, by whom, for how long, and — from the employee afterward — what was asked and said.

Preserve everything and issue the hold before the end of the day.

Then move immediately to the marker analysis in Step 3. A raid means the government already has information, which shortens the runway but does not always eliminate it — and a company that spends the following week in shock rather than in Step 3 has usually forfeited whatever chance remained.

Step 8A — If you were not first

Second place is the ordinary outcome, and it is a different matter with its own strategy.

Cooperate early anyway. Cooperation credit is real and it is graded on timing. The second company in receives substantially better terms than the fourth, and the difference compounds through the fine calculation, the treatment of individuals, and the government's posture in the civil case.

Establish what the leniency applicant has said. The government's theory is built on the first mover's account. Understanding its shape — the period, the participants, the mechanism — tells you what you are defending and where the account may be incomplete or self-serving.

Contest the scope, not the existence. Once a leniency applicant has described the conspiracy, denying that any agreement occurred is rarely productive. What is productive is narrowing it: which products, which geographies, which period, which of your employees, and whether particular conduct was within the agreement or independent.

Fight the volume of affected commerce. It is the base of the fine calculation under the Guidelines and the anchor of the civil damages claim. Sales outside the conspiracy's product scope, geography, or time period should be excluded, and the work of excluding them pays twice.

Protect the individuals who can be protected. Negotiate the carve-outs. An employee who was peripheral, who was following instructions, or who ended their involvement early may be defensible, and the company's advocacy matters even though the interests are not identical.

Consider whether any conduct is genuinely outside the per se categories. Not every competitor contact is a cartel. Information exchange, joint venture conduct, and legitimate benchmarking are analyzed under the rule of reason and are not criminal — and a matter that begins as a cartel investigation sometimes narrows substantially when the conduct is properly characterized.

Then plan for the civil case from the start, because 15 U.S.C. § 16(a) will make the plea's factual admissions prima facie evidence against you, and the admissions are negotiable.

Step 9A — Managing the company while the investigation runs

A cartel investigation is a multi-year event happening to an operating business, and the operational management is a real part of the work.

The people in the investigation still have jobs. Employees under scrutiny cannot simply be removed — a termination during an investigation looks like retaliation or scapegoating, and it complicates cooperation. Make personnel decisions on documented grounds, with counsel, and consider administrative leave rather than termination while facts develop.

Advancement and indemnification. Executives will demand advancement of defense costs, and the charter, bylaws, and applicable law determine what is owed. Address it early and consistently; ad hoc decisions about who gets counsel create their own claims.

The commercial disruption of termination. Leniency requires prompt and effective termination of the conduct, which in a price-fixing matter means the company begins competing on price in a market where its rivals may not yet be. That has real revenue consequences, and the business needs to be told why.

Customer relationships. Customers will learn — from a public charge, from the class action, or from the company. Decide in advance who says what, and recognize that customers who are also plaintiffs are in an awkward commercial position that some will exploit.

Information containment. The investigation is known to a small group. Expanding that group expands the privilege problem and the leak risk, and in a leniency matter a leak can alert competitors and complicate the government's investigation — which is a cooperation problem.

Board governance. Regular reporting to the audit committee, minutes that reflect oversight without creating a discoverable narrative of the underlying conduct, and a clear decision record for the marker, the cooperation, and any plea.

Insurance and reserves, per Step 9.

And the long tail. Four years is a long time in a company's life. People who made key decisions will leave; institutional memory will fade. Keep a single, maintained chronology from day one — it is the document that saves the matter when the third set of lawyers arrives.

Step 10A — Handling the grand jury phase

Between the marker and the resolution sits a grand jury investigation, and it has its own mechanics.

Document subpoenas. Negotiate scope with the prosecutor as you would a civil demand — custodians, date range, and format are all negotiable, and prosecutors accommodate reasoned proposals. Produce on a rolling basis, log privilege carefully, and never produce late without an agreed extension.

Testimony subpoenas to employees. Every witness needs their own counsel. Prepare with documents, not themes: a witness who has read their own emails and understands what was happening is credible; one who has been told the company's position and not shown the record will be impeached with it.

Teach three habits. Answer the question asked. Say "I don't recall" when true. Do not speculate about what a document meant if you did not write it. And remember there is no defense counsel in the grand jury room — the witness steps out to consult, which is permitted and unremarkable.

Immunity offers. Prosecutors may offer letter immunity or statutory use immunity to employees in exchange for testimony. That is between the individual and the government, and the individual's counsel advises on it. The company should not attempt to influence it, and any appearance of doing so is dangerous.

Target, subject, witness. These designations matter and they change. Counsel should ask, and should ask again as the investigation develops, because a witness who becomes a subject needs different advice.

The company's own status. A corporation can be a target. Ask.

And watch the parallel proceedings. Civil discovery, foreign investigations, and any regulatory inquiry generate statements usable in the criminal matter. Coordinate counsel across all of them, and seek a stay of the civil case where the overlap is real.

Step 11 — How Marchgate's four years ran

Day 0. An expense audit flagged six dinners over two years between a commercial vice president and counterparts at two competitors, none on any published agenda. Vasilenko-Achebe pulled the calendar and found the dinners preceded quarterly price announcements by two to nine days, consistently.

Day 0. She called criminal antitrust counsel that afternoon rather than investigating further. That decision — resisting the instinct to know more first — is the one the whole outcome turned on.

Day 1. Litigation hold across email, chat, calendars, expense and travel systems, phone records, and eleven individuals' personal devices, with written IT confirmation for each system. Affirmative no-destruction instruction issued and documented.

Day 3. Marker sought and obtained, on a pattern of dinners and a timing correlation.

Days 4–7. Local counsel engaged in four foreign jurisdictions; parallel applications filed within the week.

Days 7–35. Internal investigation. Separate counsel for five individuals within the first ten days. The vice president, represented, described a four-year arrangement among three producers to signal quarterly price movements.

Day 36. Full proffer. Conditional leniency letter signed.

Years 1–3. Cooperation: 2.4 million documents, twenty-eight witness interviews, five employees before the grand jury, and assistance in the prosecution of two competitors and four individuals.

Month 14. Follow-on class actions filed within a week of the first public charge against a competitor. Marchgate designated ACPERA cooperation immediately and logged every production and interview.

Year 4. The court found the cooperation satisfactory. Marchgate paid single damages on its own sales — about $28 million — against a modeled treble joint-and-several exposure exceeding $400 million.

The former vice president, who had left the company before the application and therefore did not qualify for individual coverage, was convicted and sentenced to a custodial term.

Vasilenko-Achebe's summary: "Three days of facts and one phone call was worth roughly four hundred million dollars. Everything else we did was competent and none of it mattered as much."
