To provide statistically accurate results, the State of Oregon experience rating plan does the following:

- It does not depend entirely on the company’s own loss experience.
- It gives more weight to small losses than to large losses.
- It caps the maximum surcharge that can be applied.
- Using incorrect classification codes or payroll allocations
- Failing to include all payroll data when calculating expected losses
