US regulators have urged Congress to ensure its proposed asbestos litigation reform is fair to insurers.
The trust is intended to stop a flood of asbestos-related lawsuits that studies say could end up costing more than $200bn (£122bn).
The call by the National Association of Insurance Commissioners (NAIC), was welcomed by the American Insurance Association (AIA), which praised the decision by the NAIC to adopt a resolution demanding effective asbestos litigation reform.
The resolution calls for "properly constructed, reasonable and balanced mechanism[s]" for funding asbestos liabilities.
Last week, President of the American Insurance Association (AIA), Robert Vagley, said the $52bn (£36bn) insurers would be asked to provide as core funding would be "unsustainable".
Last month leading plaintiff lawyers raised concerns that the trust may threaten existing settlements. They also claimed that settlements could become incorporated into the trust.
Peter Kraus, a lawyer who represents cancer victims in the Halliburton case, said: "Hatch's trust will deep-six all settlements that are not full and binding. Companies like Halliburton are banking on the trust because it would lower their overall dollar contribution regardless of what they are now saying."
