On January 30, 2026, the Massachusetts Appeals Court reversed a reviewing board denial and ruled that Employer’s Reinsurance Corporation (ERC) can claim reimbursement from the state Workers’ Compensation Trust Fund for cost-of-living adjustment (COLA) payments it made on behalf of a Polaroid employee injured in 1979. Polaroid, once a licensed self-insurer, went bankrupt in 2004. The claim is still generating payments 47 years after the original injury.
Justice Ditkoff’s panel held that Massachusetts law lists exactly three categories of employers ineligible for trust fund reimbursement, and that regulators cannot create a fourth by administrative action. The reviewing board had relied on a 2015 precedent to deny ERC’s claim; the court found that precedent misapplied the statute.
Who It Affects
The ruling matters most to self-insured employers with workers’ comp programs that carry permanent total disability (PTD) exposure: manufacturers, large municipalities, hospital systems, and any entity whose workforce faces serious injury risk. It also directly affects excess carriers and reinsurers backing those programs, because Massachusetts law treats reinsurance contracts as direct obligations to injured workers, with contrary contractual provisions null and void. Other participating self-insured employers in the state pool may bear higher assessments when an insolvent employer’s claims flow through the trust fund.
The Reserve Mechanism
The Talbert claim is a case study in extreme tail length. Annie Talbert was injured in 1979. Her permanent total disability determination came in 1986. The $250,000 reinsurance attachment triggered years later. Greenwich Insurance’s surety bond, which backstopped Polaroid’s self-insured obligations, exhausted by 2013. ERC filed its trust fund reimbursement claim in May 2017. The reviewing board did not decide until November 2021, and ERC did not learn of the denial until November 2024. The appeal was resolved in January 2026.
For actuaries calibrating workers’ compensation tail factors, this timeline is a stress test. Standard paid development patterns for indemnity often assume that claims are substantially developed by maturity year 15 or 20. PTD claims with COLA adjustments can generate incremental payments for 40 or more years. If the tail factor applied to recent accident years does not reflect this run-off length, the reserve estimate will understate the ultimate for the most serious claims.
The ruling also raises questions about collateral adequacy. Self-insured employers post security deposits, surety bonds, or letters of credit to guarantee their obligations. If those instruments are sized to a 20-year horizon but the actual liability extends to 40 or more years, the collateral will exhaust well before the claim closes, exactly as Greenwich’s bond did here. The shortfall then migrates to the trust fund (and, ultimately, to other participating self-insured employers through higher assessments).
What to Ask Your Actuary
- Are our WC indemnity tail factors for permanent total disability claims calibrated to a 40-plus-year payment horizon, or do they truncate at a shorter maturity? What data supports the selected cutoff?
- Is our posted collateral (surety bond, letter of credit, or security deposit) sized to cover full run-off exposure if the organization were to cease operations, including COLA-adjusted payments on open PTD claims?
- Have we stress-tested the Bornhuetter-Ferguson expected claim ratio for our most recent accident years against the possibility that a single PTD claim generates payments for decades beyond the triangle’s observed development period?
What to Watch Next
The key question is whether other states adopt similar reasoning about reinsurer access to guaranty or trust fund mechanisms after self-insured employer insolvency. If they do, state regulators may respond by increasing collateral requirements to account for this expanded tail exposure. Watch for any legislative or regulatory proposals in Massachusetts or other major self-insurance jurisdictions that revisit security deposit formulas in light of this ruling.
