The changes are to the California Experience Rating Plan (ERP). This is the mandatory plan that produces experience modifications (ex-mods) for all California employers that have sufficient payroll to qualify. The changes are effective January 1, 2010.
The changes to the ERP are based on recommendations from the Workers’ Compensation Insurance Rating Bureau’s (WCIRB) Experience Rating Task Force to improve the ex-mod’s predictive value and make it easier to understand.
Major changes to the Experience Rating Plan:
The methodology formula used for splitting actual losses into primary and excess components is changing to a “single split” model, with the first $7,000 of every loss considered primary. This change recognizes that an employer’s claims frequency is more predictive of future losses than the actual size of a given claim.
**Credibility Values Updated
Credibility values are the weights applied to an employer’s loss experience. The updates recognize that the claims experience of a large employer is more predictive of future losses than the claims experience of a small employer.
Who Is Affected by the Changes?
Most employers will experience an ex-mod change of a few percentage points under the new plan. The precise impact on employers with an experience modification factor will depend on the size of their payroll and the number and size of their losses. According to the WCIRB, an estimated 47 percent of all employers could see a decrease of up to 10 points under the plan.
