What is a settlement matrix?

A settlement matrix is a structured method for evaluating individual claims within some large settlements.

Mass torts can involve thousands of people who allege similar injuries but have very different individual circumstances.

For example, two plaintiffs may have used the same product but experienced:

• Different injuries
• Different levels of severity
• Different treatment
• Different duration of exposure
• Different medical histories
• Different long-term consequences

Rather than negotiating every participating claim from scratch, a settlement program may establish objective criteria for evaluating claims.

Those criteria are sometimes organized into a settlement matrix.

A matrix may assign a claimant to a particular:

• Category
• Tier
• Level
• Point total
• Award range
• Base award

The terminology varies from one settlement to another.

How does a settlement matrix work?

There is no single formula.

A settlement agreement first defines which claims are eligible and what information matters.

The settlement administrator or another designated decision-maker then reviews evidence for each participating claimant.

Depending on the settlement, that evidence may determine:

1. Whether the claim qualifies.
2. Which injury category applies.
3. Which settlement tier applies.
4. Whether points or adjustments apply.
5. Whether deductions or reductions apply.
6. Whether the claimant qualifies for additional compensation.
7. The claimant's final settlement offer or award.

The Paraquat MDL provides a current real-world example. In an April 8, 2026 order, the U.S. District Court for the Southern District of Illinois referred specifically to each eligible plaintiff's “assigned settlement matrix tier and settlement offer” and the information used to determine them. (Illinois Southern District Court)

That does not mean every mass tort uses the same system.

Why are settlement matrices used?

Large mass-tort settlements face a difficult problem:

How do you evaluate thousands of individual claims consistently without pretending every injury is the same?

A matrix can provide a structured answer.

Its goals may include:

• Treating similar claims consistently.
• Recognizing meaningful differences among injuries.
• Processing large numbers of claims efficiently.
• Reducing repeated individual negotiations.
• Creating transparent eligibility requirements.
• Providing a repeatable method for calculating awards.

The 3M Combat Arms Earplug settlement provides one example. The federal court appointed a Settlement Allocation Master responsible for designing an allocation methodology applicable to eligible claimants, with the settlement administrator applying that methodology to calculate individual awards. (Northern District of Florida)

Is a settlement matrix the same thing as a settlement?

No.

A settlement is the agreement resolving legal claims.

A settlement matrix may be one part of the agreement's system for distributing money among participating claimants.

A settlement can exist without a matrix.

And the existence of a proposed or hypothetical matrix does not mean a settlement has occurred.

This distinction matters because online mass-tort advertising sometimes publishes supposed “settlement matrices” or payout charts before any actual settlement agreement exists.

Those projections are not official settlement matrices.

What factors can a settlement matrix consider?

The factors depend entirely on the litigation.

Potential factors may include:

Type of injury

Different diagnoses may receive different classifications.

Severity

A permanent or catastrophic injury may be treated differently from a temporary injury.

Medical treatment

The matrix might distinguish among:

• Diagnosis only
• Medication
• Hospitalization
• Surgery
• Multiple surgeries
• Long-term treatment

Duration

Long-lasting injuries may be treated differently from conditions that resolved quickly.

Exposure

Toxic-exposure settlements may consider:

• Length of exposure
• Intensity
• Location
• Occupational exposure
• Documented product use

Age

Some programs may consider age at diagnosis, injury, or exposure.

Other risk factors

A program may adjust compensation based on alternative causes or medical risk factors.

Supporting evidence

The amount and quality of documentation can matter.

These are examples only.

The actual settlement documents control.

What is a settlement tier?

A settlement tier is a category used to group claims with similar characteristics.

A simplified hypothetical system might look like this:

But actual settlement programs can be much more complicated.

Some use:

• Many tiers
• Subcategories
• Point systems
• Base awards
• Adjustments
• Extraordinary-injury programs

And some do not use tiers at all.

The Paraquat settlement process demonstrates that tiers can have direct financial consequences: the federal court's April 2026 order required information concerning each eligible claimant's assigned settlement matrix tier and settlement offer. (Illinois Southern District Court)

What is a points matrix?

A points matrix assigns numerical values to characteristics of a claim.

The points can then be used to determine compensation.

An actual example appears in the federal Actos Resolution Program. The U.S. District Court for the Western District of Louisiana maintains the official settlement materials, including a document specifically identified as the Points Matrix. (U.S. Courts Law Document System)

A points system might consider factors such as:

• Injury
• Severity
• Duration
• Exposure
• Treatment
• Age
• Other medical characteristics

But the factors and values must come from the particular settlement.

There is no standard points system used across mass torts.

Is a settlement matrix the same as a settlement calculator?

Not necessarily.

An official settlement program may use formulas that function like a calculator.

But an online “mass tort settlement calculator” created by a marketer or law firm may simply be an estimate.

Unless the calculator is based on an actual settlement agreement, it cannot know:

• Whether a settlement will occur.
• How much money will be available.
• What injuries will qualify.
• What tiers will exist.
• What points will be assigned.
• What deductions will apply.

A calculator built before settlement terms exist is a prediction, not an official award calculation.

Does every mass tort use a settlement matrix?

No.

There is no requirement that mass-tort cases settle through a matrix.

Claims may instead be resolved through:

• Individual negotiations
• Fixed payments
• Settlement tiers
• Points systems
• Individual evaluations
• Mediation
• Trial
• Combinations of several approaches

Even large MDLs can use very different settlement structures.

Who creates a settlement matrix?

It depends on the settlement.

A framework may be developed through negotiations involving:

• Plaintiffs' leadership
• Defendants
• Settlement counsel
• Mediators
• Special masters
• Allocation specialists
• Settlement administrators

The 3M Combat Arms Earplug litigation provides a particularly clear example.

The federal court appointed:

• A Settlement Administrator
• A Settlement Allocation Master
• An Extraordinary Injury Fund Special Master
• A Settlement Data Administrator
• A Settlement Special Master

The Settlement Allocation Master was tasked with developing an allocation methodology, and the settlement administrator was responsible for applying it to eligible claimants. (Northern District of Florida)

Who decides which settlement tier you are in?

The settlement agreement establishes the process.

Depending on the program, the initial determination might be made by:

• A settlement administrator
• Claims administrator
• Allocation master
• Special master
• Neutral reviewer
• Another designated entity

The decision should be based on the evidence required by the settlement.

That may include:

• Medical records
• Diagnostic testing
• Product records
• Exposure evidence
• Employment records
• Military records
• Pharmacy records
• Surgical records
• Other required documentation

The process varies substantially by settlement.

What is a settlement administrator?

A settlement administrator helps implement a settlement program.

Responsibilities may include:

• Receiving claims.
• Collecting documents.
• Reviewing eligibility.
• Applying settlement criteria.
• Communicating with claimants or counsel.
• Calculating awards.
• Managing deadlines.
• Processing payments.

In the 3M Combat Arms Earplug settlement, the federal court appointed ARCHER Systems as Settlement Administrator and directed it to apply the Settlement Allocation Master's methodology to calculate awards for eligible claimants. (Northern District of Florida)

What is a settlement allocation master?

A settlement allocation master may be responsible for developing or supervising the methodology used to distribute settlement funds.

In the 3M litigation, the court directed the Settlement Allocation Master to design an allocation methodology applicable to eligible claimants and review the administrator's application of that methodology. (Northern District of Florida)

Not every settlement uses an allocation master.

What is an Extraordinary Injury Fund?

Some settlements establish an Extraordinary Injury Fund, often abbreviated EIF.

This can provide additional compensation to claimants whose circumstances exceed what the ordinary settlement framework adequately captures.

For example, the 3M court directed its Settlement Allocation Master and EIF Special Master to establish criteria and procedures for eligible claimants seeking additional compensation from an extraordinary injury fund. (Northern District of Florida)

An EIF might potentially address unusually severe:

• Injuries
• Medical treatment
• Complications
• Economic losses
• Other qualifying circumstances

The actual eligibility rules depend on the settlement.

Does being in a higher tier always mean a bigger settlement?

Usually a settlement's classifications are designed to recognize differences among claims, but you should not assume what a particular tier means without reading the actual agreement.

For example:

• Tier numbering may run high-to-low or low-to-high.
• Adjustments may apply after the initial tier.
• Point values may matter more than the tier itself.
• Extraordinary compensation may be separate.
• Reductions may apply.

“Tier 1” does not universally mean the same thing across mass torts.

Can two people with the same diagnosis receive different settlements?

Yes.

A diagnosis may be only one part of the calculation.

Two claimants with the same disease could differ in:

• Age at diagnosis
• Severity
• Surgery
• Treatment
• Duration
• Exposure
• Product use
• Medical history
• Other risk factors
• Documentation
• Economic losses

If those factors are part of the settlement methodology, the resulting awards may differ.

Can a settlement matrix reduce an award because of other risk factors?

Potentially.

Some settlement programs include adjustment factors.

For example, a program could account for medical or lifestyle factors that may provide another explanation for an injury.

Depending on the litigation, examples might include:

• Smoking history
• Pre-existing disease
• Alternative chemical exposures
• Age
• Other medications
• Prior injuries

But these reductions are not universal.

They must be established by the actual settlement terms.

Can a settlement matrix increase an award?

Potentially.

Some programs provide additional compensation for circumstances such as:

• Particularly severe injuries
• Multiple surgeries
• Permanent impairment
• Extraordinary medical treatment
• Significant economic losses
• Other defined factors

An Extraordinary Injury Fund is one possible way to handle claims that exceed the ordinary matrix.

What evidence determines a settlement matrix award?

The settlement agreement determines what evidence is acceptable.

Common examples can include:

Medical evidence

• Medical records
• Diagnostic reports
• Pathology
• Surgical records
• Hospital records
• Physician documentation

Exposure or product evidence

• Prescription records
• Pharmacy records
• Product identification
• Employment records
• Military records
• Purchase records

Damages evidence

• Medical bills
• Wage records
• Disability records
• Other financial documentation

A claimant's description of an injury may not be enough if the settlement requires objective documentation.

What happens if records are missing?

That depends on the settlement.

Some programs establish alternative proof procedures.

Others require specific documentation.

Possible alternatives might include:

• Affidavits
• Secondary records
• Employment evidence
• Pharmacy data
• Military records
• Other approved evidence

But claimants should not assume missing records will automatically be excused.

The settlement agreement controls what proof is acceptable.

Can you appeal your settlement matrix classification?

Sometimes.

A settlement program may provide a process for challenging:

• Eligibility
• Tier assignment
• Points
• Adjustments
• Award calculation

The process might involve:

• Reconsideration
• Administrative review
• Special-master review
• Arbitration
• Another defined appeal procedure

For example, a federal court order in pelvic-repair-system litigation authorized a special master to act as the final and binding arbitrator for appeals involving settlement allocations. (Southern District of West Virginia)

Not every settlement provides the same appeal rights.

What happens if you disagree with your settlement offer?

Your options depend on the settlement agreement and whether you have agreed to participate.

Possible choices might include:

• Requesting review.
• Appealing the classification.
• Providing additional documentation.
• Rejecting the settlement.
• Continuing litigation.

Those options can have significant consequences.

In the 2026 Paraquat settlement process, the court appointed a special master to meet with plaintiffs who opted out or had not made an election so that they understood their rights and obligations if they chose not to participate. (Illinois Southern District Court)

That illustrates why opting out is not simply a request for a higher number.

It can mean returning to litigation.

Can you reject a settlement matrix award and go to trial?

Potentially, depending on the agreement and procedural posture of the case.

A plaintiff who rejects a settlement may retain the right to continue litigating.

But continued litigation can involve:

• Additional discovery
• Expert requirements
• Court deadlines
• Motions
• Trial risk
• Litigation expenses
• Possible dismissal
• A defense verdict

Rejecting an offer does not guarantee a better result.

Does opting into a settlement usually end your lawsuit?

If the settlement is completed and the required release becomes effective, participating claimants generally give up the claims covered by that release.

The exact scope matters.

A release may specify:

• Which defendants are released.
• Which claims are released.
• When dismissal occurs.
• What rights remain, if any.

Claimants should understand the actual release rather than assuming what participation means.

Is the settlement matrix public?

Sometimes.

Some settlement agreements and allocation documents are filed publicly with federal courts.

Others may contain confidential terms or claimant-specific information that is not public.

Examples of publicly accessible settlement structures include the Actos Resolution Program, whose official federal court page contains the settlement agreement and Points Matrix. (U.S. Courts Law Document System)

The existence of public general criteria does not mean individual claimant information is public.

How much money will I receive from a settlement matrix?

You cannot reliably determine that without the actual settlement methodology and your verified claim information.

The calculation may depend on:

• Eligibility
• Injury tier
• Points
• Adjustments
• Documentation
• Extraordinary-injury eligibility
• Settlement fund structure
• Other terms

An online article cannot determine an individual settlement award simply from a diagnosis.

Is the matrix amount what the claimant takes home?

Not necessarily.

A gross settlement award may be different from the claimant's final net payment.

Potential deductions can include:

• Attorney fees
• Case expenses
• Medical liens
• Medicare reimbursement
• Medicaid reimbursement
• Health-plan reimbursement
• Common-benefit assessments where applicable
• Other authorized deductions

The actual deductions depend on the case and settlement.

What are common-benefit fees?

Large MDLs often require plaintiffs' leadership to perform work that benefits many claimants, such as:

• Corporate discovery
• Depositions
• Expert development
• Motion practice
• Bellwether preparation

Courts may establish procedures for compensating attorneys who performed this common-benefit work.

Those procedures are separate from the settlement matrix itself but can affect settlement administration or distributions in some proceedings.

For example, the official Actos MDL settlement page separately identifies court orders concerning common-benefit fees and costs. (U.S. Courts Law Document System)

What are medical liens?

A medical lien or reimbursement claim can arise when another program or insurer paid healthcare expenses related to the injury being compensated.

Potential reimbursement interests can involve:

• Medicare
• Medicaid
• Private health plans
• Other payers

Valid liens or reimbursement obligations may need to be resolved before final settlement proceeds are distributed.

That means a matrix award should not automatically be interpreted as the amount a claimant will receive in their bank account.

Is a settlement matrix fair?

A matrix is intended to create a consistent framework, but whether a particular methodology fairly values an individual claim can be disputed.

Courts sometimes appoint neutral administrators, special masters, or allocation experts to help oversee settlement programs.

For example, in one federal pelvic-mesh proceeding, the court tasked a special master with determining whether settlement allocation and distribution provided fair and reasonable compensation based on factors including medical evidence, scientific evidence, litigation risk, cost, and delay. (Southern District of West Virginia)

The fairness of any particular matrix depends on its actual terms and the facts of the litigation.

Is a settlement matrix created before or after bellwether trials?

Either is possible.

There is no required sequence.

In some mass torts:

1. Discovery occurs.
2. Bellwether cases are tried.
3. The parties use trial results to evaluate risk.
4. Settlement negotiations accelerate.
5. An allocation framework is created.

In others, settlement occurs before meaningful bellwether trials.

Bellwether trials can provide useful information, but they are not a prerequisite for creating a settlement program.

Does a large MDL mean there will eventually be a settlement matrix?

No.

An MDL can contain thousands of cases without ever producing a matrix.

Possible outcomes include:

• Individual settlements
• Global settlement
• Matrix-based settlement
• Continued trials
• Dismissals
• Remand
• Different settlements with different defendants

The number of pending cases does not predict the eventual settlement structure.

What is a settlement allocation plan?

A settlement allocation plan is a broader system explaining how available settlement funds will be distributed among eligible claimants.

A matrix may be part of that plan.

For example, the Chinese Drywall MDL used court-reviewed allocation plans to distribute settlement funds among different categories of eligible claims. The official federal court docket preserves those settlement and allocation materials. (Eastern District of Louisiana)

An allocation plan may address:

• Eligibility
• Claim categories
• Documentation
• Calculation
• Distribution
• Appeals
• Administrative costs

Can a settlement matrix change?

Potentially.

Settlement methodologies may contain procedures for:

• Corrections
• Amendments
• Administrative interpretations
• Appeals
• Supplemental awards
• Extraordinary-injury claims

But once a settlement agreement becomes binding, changes must occur within the authority and procedures established by that agreement and applicable court orders.

A claimant should rely on current official settlement materials rather than an older online summary.

How do I know whether a settlement matrix I found online is real?

Look for the underlying primary source.

A genuine settlement matrix should be traceable to something such as:

• An executed settlement agreement.
• An official settlement administrator.
• A federal court filing.
• A court order.
• An official MDL website.

Be skeptical of a page that says:

“Expected settlement matrix: Cancer = $500,000–$1 million”

when no settlement has actually been announced.

That is an estimate—not a settlement matrix.

Why do websites publish estimated mass-tort settlement amounts?

Mass-tort plaintiffs frequently want to know what their claims may be worth.

That creates substantial search demand for phrases such as:

• Average settlement
• Settlement amount
• Payout
• Settlement calculator
• Settlement matrix

Before actual terms exist, however, there may be no authoritative answer.

Some websites fill that information gap with estimates based on:

• Prior mass torts
• Jury verdicts
• Claimed injury severity
• Assumed settlement funds
• Marketing projections

Those estimates can sound much more certain than the evidence supports.

Can you calculate a mass-tort settlement from jury verdicts?

Not reliably.

A jury verdict and a settlement matrix serve different purposes.

A verdict reflects one trial involving:

• One plaintiff or defined group
• Specific evidence
• Specific defendants
• Particular state law
• A particular jury

A settlement reflects negotiated litigation risk across many claims.

Large verdicts can influence negotiations, but dividing verdict totals or averaging selected verdicts does not create a reliable settlement matrix.

Common misconceptions

Myth: Every major mass tort has a settlement matrix showing exactly how much each injury is worth.

Reality: Settlement matrices exist only when a particular settlement creates or uses one. Some mass torts use tiers, points, allocation formulas, or individual review; others use entirely different approaches. Before an actual settlement is announced, online “settlement matrix” payout estimates are predictions, not official compensation schedules.

Why this matters

A settlement matrix sounds like a simple payout chart:

You have Injury A, so you receive Amount B.

Real mass-tort settlements are rarely that simple.

A legitimate settlement matrix exists inside a larger legal agreement that defines:

Who qualifies? What evidence is required? How are injuries classified? What increases or reduces an award? Who makes the decision? Can the decision be challenged? What must the claimant release in exchange for payment?

Those details matter far more than speculative payout numbers.

The easiest way to distinguish useful information from mass-tort marketing is therefore straightforward:

If someone claims a settlement matrix exists, ask to see the actual settlement agreement, court filing, or official settlement program that created it.

If there isn't one, the numbers are estimates.
