A common-benefit assessment is a court-ordered holdback that reduces your settlement to pay shared leadership work. A settlement matrix then values different claims by injury, treatment, exposure and proof, placing stronger claims in higher tiers for larger gross awards. In a multidistrict litigation, many individual cases move together for pretrial work. Leadership builds shared proof, and the matrix turns that proof into individual dollar amounts.

How much does the common-benefit assessment take?
MDL courts create a common-benefit fund to pay court-appointed leadership for work that helps all plaintiffs. That work includes depositions, document review, experts, motion practice, bellwethers and settlement effort, according to the Stanford Center on the Legal Profession's guide to establishing common-benefit funds. Typical assessments run about 4 percent to 8 percent of gross recovery, with major MDLs ranging roughly 3 percent to 11 percent at judicial discretion, according to the LegalClarity Team's explanation of common-benefit fees. The bulk usually comes from the plaintiff lawyer's contingency fee rather than added on top.
A small shared-cost holdback around 2 percent can still reduce the client's net, according to the Lawsuit Information Center. The 3M Combat Arms earplug deal shows the scale. 3M agreed to pay 6.0 billion dollars from 2023 to 2029, according to 3M Company. Reports describe a 9 percent holdback for participants and 15 percent for nonparticipants, according to the LegalClarity Team.
How does a matrix turn facts into dollars?
Mass-tort defendants pay a global pool, then an administrator or special master divides it by tiers or points. Shares are not equal, according to the LawsuitProcess Editorial Team's guide to calculating mass-tort settlements. Matrices score injury type and severity, treatment or revision surgeries, exposure duration and intensity, age at diagnosis, lost income, and strength of medical documentation, according to HarmReport. Strong proof moves a claim up.
Weak or missing records move it down. A short hospital stay with full recovery scores below a permanent injury with repeat surgery. Longer, heavier exposure scores above brief or poorly documented exposure. Lost wages add value only when pay records tie the loss to the injury.
What do different claims actually receive?
The public Camp Lejeune Elective Option grid pays by disease tier and exposure time. Tier 1 pays 150,000, 300,000 or 450,000 dollars, while Tier 2 pays 100,000, 250,000 or 400,000 dollars, according to TorHoerman Law's 2026 guide to the Elective Option. Exposure bands are 30 to 364 days, 1 to 5 years, or over 5 years, plus 100,000 dollars for wrongful death. The uncapped NFL concussion grid works differently.
It varies payment by qualifying diagnosis and age, paying up to 6,103,448 dollars for ALS diagnosed before age 45 before reductions, according to the Nguyen Law Firm. Earlier onset and more severe diagnoses pay more. The lesson crosses cases. Fixed grids reward clear categories, longer exposure, younger age at serious diagnosis, and objective treatment history. Borderline diagnoses, late onset, and thin files fall into lower bands.
Why is your check smaller than the grid amount?
The grid sets a gross award, not take-home pay. Contingency fees, case costs, and Medicare or other medical liens come out first, according to the LawsuitProcess Editorial Team. Lien size often decides timing because the check cannot issue until liens resolve. Cases for minors add another step.
They need judicial infant-compromise approval through a Qualified Settlement Fund, according to LegalClarity. That review protects the child but delays payment. Ask your lawyer for a written net sheet before you accept an offer. Confirm the gross tier, the common-benefit holdback, the contingency fee base, costs, and each lien.
How can you protect your net recovery?
Complete records control both tier placement and speed. Gaps in treatment, missing exposure proof, and unsigned authorizations invite point cuts and delays.
- Get every diagnosis, scan, operative report, prescription, and therapy note in one file.
- List exposure dates, products, places, and witnesses with documents that back them.
- Keep pay stubs, tax forms, and employer letters for any wage claim.
- Tell your lawyer early about Medicare, Medicaid, VA, or private insurance payments.
- Ask how liens will be verified, reduced, and cleared before funds disburse.
