Insurance that covers the policyholder only for the portion of losses that exceed a certain dollar limit.
The average rate at which losses for a classification are estimated to occur during an experience rating period; they are generally expressed as a ratio per $100 of payroll. Expected loss rates, which are contained in the California Workers' Compensation Experience Rating Plan—1995, are approved annually by the Insurance Commissioner.
Experience refers to the payroll and loss information for an entity or risk. It can be defined in terms of policy year, calendar year, accident year, report year, etc.
An adjustment to an employer's premium based on comparing the employer's experience to the experience of its industry. Generally, an experience modification of less than 100% reflects better-than-average experience, while an experience modification of more than 100% reflects worse-than-average experience. Accordingly, an experience modification that is greater than 100% usually increases the cost of the employer's workers' compensation insurance premiums, while an experience modification that is less than 100% usually decreases the cost of the employer's workers' compensation insurance premiums. The experience modification formula can be found in the California Workers' Compensation Experience Rating Plan—1995.
California's workers' compensation experience rating system is a merit rating system intended to provide employers a direct financial incentive to reduce work-related accidents. The experience rating system objectively distributes the cost of workers' compensation insurance more equitably among employers assigned to particular industry classifications by deriving an experience modification for each eligible employer based on the experience rating formula in the California Workers' Compensation Experience Rating Plan—1995 (ERP). The eligibility threshold for experience rating for each year is specified in that year's ERP. Experience rating is applicable only to and mandatory for eligible employers.
Refers to the experience rating form used by the WCIRB to calculate an employer's experience modification. Also called Experience Rating Worksheet.
