Johns Manville

Johns Manville, the oldest and largest manufacturer of asbestos-based products, exposed millions of workers to asbestos for more than a century. The company filed for bankruptcy in 1982 as a result of its overwhelming asbestos-related liabilities and established an asbestos trust fund. The Manville Personal Injury Settlement Trust provides compensation to individuals exposed to asbestos through Johns Manville’s activities.

Johns Manville was founded in 1858 and thrived as the world’s largest producer of asbestos products until it filed for Chapter 11 bankruptcy protection in 1982.

At its peak, Johns Manville operated dozens of sites in the United States and overseas and boasted 30,000 employees, according to the California Supreme Court. Despite its harm to millions of people, the company is still in business and thriving today.

The Lanier Law Firm specializes in holding large asbestos companies accountable and helping those who have been harmed recover the financial compensation they need and deserve.

The Manville Personal Injury Settlement Trust

In 1973, Johns Manville lost a landmark asbestos case, Clarence Borel v. Fibreboard Paper Products Company, et al. This was the first case to hold defendants liable for asbestos exposure, and it sparked a barrage of lawsuits against Johns Manville.

The burden of asbestos liability threatened the company’s solvency, so in 1982, Johns Manville filed for bankruptcy. As part of the bankruptcy restructuring, the company agreed to establish an asbestos trust fund for the benefit of present and future claimants.

The Manville Personal Injury Settlement Trust became operational in 1987, although final approval was granted in 1988. Initially, the fund was established with $2.5 billion in anticipation that the fund would receive 83,000 to 100,000 claims throughout its lifetime.

Johns Manville had significantly undershot its liabilities. The trust ran out of funds by 1990 and was forced to contribute an additional $520 million to the fund and restructure its process as hundreds of thousands of claimants continued to come forward.

As of the end of December 1995, approximately 280,000 claims had been received. By this time, Chapter 11 bankruptcy laws had been amended with the addition of § 524 (g), which specifically shielded bankrupt asbestos companies from further liability. As of the end of the third quarter of 2022, the trust fund’s net claimants equity totaled $509,529,098.

Trust fund claims are processed and paid out on a first-come, first-served basis, so it is important to file a claim as soon as possible after becoming eligible.

Claims Eligibility

You may be eligible to receive compensation if you meet the following criteria:

  1. You have a medical diagnosis of an asbestos-related illness
  2. You can prove Johns Manville is responsible for your exposure to asbestos

You will be required to provide documentation supporting your claims.

How is compensation calculated?

Upon receipt of your claim, the trust will determine whether you fit the criteria for one of the eight categories of disease and make an offer on this basis. You will then have the option of accepting or disputing the offer.

If you dispute the offer or your illness is outside the standard eight conditions, your claim must be calculated on an individual basis, in which case your claim will be evaluated based on the following:

  • The nature of your disease
  • Current tort law in your jurisdiction
  • The claim values of tort litigants in your jurisdiction with similar circumstances


The maximum values range between $600 and $350,000. However, in some cases these can be increased. Not all claims qualify for maximum values.

The payout you receive will be a percentage of your claim value, known as the pro rata share. The purpose of reducing your claim to this amount is to ensure the trust retains enough funds to pay compensation to all present and future claimants. The current pro rata share is 5.1 percent of your claim value.

What are the eight disease categories?

I. Other asbestos disease
II. Mild asbestosis with pleural disease
III. Moderate asbestosis with pleural disease
IV. Severe asbestosis with pleural disease
V. Other cancer
VI. Lung cancer without bilateral asbestos-related non-malignancies
VII. Lung cancer with an underlying bilateral asbestos-related non-malignant condition
VIII. Mesothelioma

If your asbestos exposure was primarily through Johns Manville or if you have exceedingly high medical costs associated with your asbestos-related illness, you may qualify for an extraordinary claim. In an extraordinary claim, your claim value may exceed the established maximum value for your disease category.

How long does it take to process a claim?

Standard or expedited claims can be paid out within a few months, depending on the number of claims ahead of yours. Most claims are handled on a first-in, first-out basis. If your claim requires individual review, you can expect a longer processing time.

When can claims be expedited?

You may qualify for an expedited claim if you have a hardship, including the following:

  • Your life expectancy is six months or less because of your asbestos-related illness
  • You have a dire financial need that can be causally connected to your asbestos-related illness

The Origins of Johns Manville

Johns Manville was the product of a merger between two companies: H.W. Johns Manufacturing Company, established in 1858 in New York City, and Manville Covering Company, established in 1886 in Milwaukee, Wisconsin.

These companies specialized in asbestos roofing material and asbestos heat-insulating materials, respectively. They merged in 1901 as the H.W. Johns-Manville Manufacturing Company and incorporated as Johns-Manville Corporation in 1926.

Johns Manville was a major supplier of asbestos to the military throughout World War II and quickly grew to an international presence. The company owned and operated the world’s largest asbestos mine, located in Quebec, Canada.

When did Johns Manville learn about
the dangers of asbestos?

In 1933, Dr. Anthony J. Lanza, the medical director of the Metropolitan Life Insurance Company, reported findings to Johns Manville and another major asbestos company, which revealed that asbestos exposure causes lung disease.

The companies conspired to withhold this information from the public, and Johns Manville’s attorney wrote Dr. Lanza a letter specifically requesting that he downplay the risks of asbestos. Dr. Lanza complied.

Johns Manville funded additional asbestos studies, conducted by Saranac Laboratories in New York, under the direction of Dr. Leroy Gardner, who was prohibited from publishing his findings without permission from Johns Manville. Shortly before his 1946 death, he expressed distress about this cover-up.

Occupational Exposure by Johns Manville

Johns Manville’s miners and factory workers experienced significant asbestos exposure. The level of asbestos exposure was so extensive that some workers were known as “snowmen” because the white asbestos dust completely covered them.

The factories also emitted asbestos dust into the surrounding environment. One woman who lived a block away from a Johns Manville factory told the Los Angeles Times that her vegetable garden was regularly covered in asbestos dust.

Johns Manville’s employees were not the only workers who experienced significant asbestos exposure. Workers in the following occupations may also have been exposed to Johns Manville asbestos:
