Experience Rating Production Service
The Experience Rating Plan is a state-mandated program that uses an individual employer’s actual incurred loss experience and compares it to average losses of similarly classified businesses. The resulting modification factor is used to adjust workers compensation manual rates to reflect the expected loss experience of an insured. NCCI identifies and collects the employer’s payroll and loss information, develops the rating, and distributes it to the insurer.
