Workers’ compensation insurance and self-insurance


Following are highlights for 2022.

  • Workers’ compensation total system written premiums in Oregon totaled $998.6 million for 2022, up 5.8 percent from 2021.
  • SAIF Corporation’s share of the market in 2022 was 54 percent. Private insurers’ market share was 32.2 percent. Self-insured employers and employer groups had the remainder of the market, 13.8 percent.

Oregon law requires that every employer provide workers’ compensation coverage for its employees. Employers may have several insurance options:

  • Purchasing insurance through a private insurance company
    • Purchasing regular workers’ compensation policies
    • Purchasing large-deductible insurance polices
  • Purchasing insurance through SAIF Corporation, the nonprofit state fund
  • Getting insurance through the assigned risk pool
  • Becoming self insured

The Division of Financial Regulation (DFR) regulates the financial, rate, and trade practices of insurance companies. The Workers’ Compensation Division (WCD) regulates benefits, coverage, and claims practices for the workers’ compensation system. WCD also regulates self-insured employers.

The Oregon Insurance Guaranty Association (OIGA) is an insurance organization that pays claims costs when one of its member insurers becomes insolvent. Membership is mandatory for all private insurers. The OIGA collects assessments from its insurers to cover these costs.

Total system written premiums and the workers’ compensation premium assessment

To capture the size of the entire workers’ compensation system, the department defines total system written premiums as:

  • Premiums written by SAIF and private insurers
  • Credits from the large-deductible premium policies issued by private insurers, and
  • Simulated premiums that are calculated for each self-insured employer and self-insured employer groups.

The following table shows the size of the Oregon workers’ compensation system.
