Ohio’s Bureau of Workers’ Compensation approved a $1 billion policyholder dividend on September 3, 2026, representing roughly 90% of premiums paid in policy year 2022 and bringing the total distributed under the DeWine administration to $10.2 billion. The next day, SAIF Corporation, Oregon’s state-chartered workers’ compensation carrier, declared a $50 million dividend for 50,138 policyholders, its 17th consecutive annual distribution. SAIF named the mechanism directly: the payout was “supported in part by favorable reserve development in 2025, reflecting continued declines in claim frequency.”
That phrase deserves attention from risk managers who are not SAIF policyholders.
Where the surplus comes from
State fund dividends funded by prior-year reserve development return money the fund held for accident years that closed better than priced. SAIF’s distribution covers policies ending in 2025, which reflects claim experience from accident years 2019 through 2022, years when lost-time claim frequency fell sharply and ultimates came in below actuarial expectations. Ohio BWC’s $1 billion equals roughly 90% of 2022 policy-year premiums for the same reason: those years performed better than expected, and the surplus is now being returned.
Self-insured employers cannot replicate this transaction. The redundancy belongs to the fund.
The calibration problem
When a self-insured employer uses state fund loss ratios, industry benchmarks, or development triangles calibrated through 2022 to set its expected claim rate or IBNR, it imports the favorable development those accident years produced. That historical record is accurate; it is not a forecast for the open 2025 accident year.
The current environment is different. NCCI’s 2026 State of the Line analysis places the workers’ compensation accident year 2025 combined ratio at 102%, driven by rising medical severity and a slower frequency decline than the 2019-2022 period. Industry reserve redundancy, approximately $16 billion in 2024, has eroded to roughly $14 billion as prior favorable development runs out. SAIF acknowledged the shift directly: the same announcement that cited favorable development also listed “rising medical costs, investment uncertainty, and future capital needs” as constraints on future dividend levels.
A development factor derived from triangles heavily weighted toward accident years 2019 through 2022 will systematically understate IBNR for the open 2025 accident year. The historical tail was shorter and the development more benign than what is now emerging.
Who this affects
Self-insured manufacturers, public entities, hospital systems, and captive groups that benchmark ECRs against state fund published loss ratios or industry development triangles anchored to the 2019-2022 experience block are most exposed to this calibration drift. It is a structural problem, not a judgment call: the benchmark contains a favorable bias that no longer matches the open year.
What this means for your next review
Ask your actuary whether the development factors in your current reserve study draw heavily on accident years 2019 through 2022 and whether those factors have been adjusted for the development direction now visible in accident year 2025. The calendar-year combined ratio of 91% looks healthy because prior-year releases are still flowing through; the accident-year reading of 102% reflects where open years are heading. Development selected from the former without recalibration for the latter overstates the favorability of the current reserve position.
