A settlement matrix — a grid that assigns a fixed dollar amount to each claim type — values different claims by strength of causation proof, injury severity and length of exposure. Stronger proof with longer exposure falls in a higher-paying tier, while weak causation falls in a lower tier or drops out. Mass torts with thousands of similar injuries need this sorting to stay workable. One common fight over expert proof can otherwise stall every case at the same time.

Why does one causation ruling affect thousands?
Federal judges act as gatekeepers for expert testimony under Rule 702. One exclusion order can therefore collapse a large group of claims at once.
That happened in In re Zantac MDL 2924, where the court excluded general-causation experts and granted summary judgment against more than 2,450 plaintiffs, according to Winston & Strawn in the Zantac MDL decision analysis. Matrices are built with that risk in mind. They discount diseases with weak proof and reward documented diagnosis, longer exposure and objective testing.
How does a two-factor grid set dollar amounts?
The Camp Lejeune Elective Option uses a two-by-three grid, according to the U.S. Department of Justice. It sets offers by disease-causation strength and by duration of residence or work at Camp Lejeune.
Tier 1 covers kidney, liver and bladder cancers, leukemia and non-Hodgkin's lymphoma. Those claims draw $150,000 for 30-364 days, $300,000 for 1-5 years and $450,000 for over five years, according to the U.S. Department of Justice Civil Division in the Camp Lejeune claims guide. Time on base directly controls the cell and the payment.
What happens to lower-causation diseases?
Tier 2 covers multiple myeloma, Parkinson's disease, end-stage kidney disease and systemic sclerosis/scleroderma. Those claims draw $100,000, $250,000 or $400,000 on the same exposure ladder.
Death from the illness adds $100,000, for a $550,000 maximum, according to the U.S. Department of Justice Civil Division. The structure is explicit: possible rather than substantiated linkage means a lower base amount.
What moves a claim up or down inside a tier?
Approved mass-tort settlements usually allocate through a tiered or point-based system, according to Wisner Baum in the mass-tort settlement timeline. Tiers or points turn on injury severity and permanency, provable medical expenses and quality-of-life impact.
Objective proof matters as much as the label. Longer exposure, a clear diagnosis and test results support a higher placement than symptoms alone.
- treating-doctor diagnosis with date and ICD code
- exposure record with start and end dates
- imaging, pathology, pulmonary or hearing test results
- hospital bills, pharmacy records and lost-work notes
- daily-function statement tied to medical findings
What does fund size mean for individual checks?
A fixed fund caps every tier. 3M Company said it would contribute $6.0 billion between 2023 and 2029, with $5.0 billion in cash plus $1.0 billion in stock, for Combat Arms Earplug claims.
More than 99% of claimants joined by the March 25, 2024 final registration date, according to 3M Investor Relations. High participation lets the fund pay out, but it also means each tier shares the pool with many others. Pull your diagnosis, exposure and expense records before you accept a tier assignment.
