Unexperienced in Experience Modification Factors? Written by Mark Kraemer on 7/13/2016 2:26 AM in Workers Comp Insurance, Business Tips, Workplace Injury Management Tips. It has 0 Comments. The mechanics of experience modification factors can be confusing, with potential adjustments throwing a wrench into your understanding of this relatively straightforward practice. How does experience modification affect your Minnesota workman's comp insurance costs? Comprehending calculations Once your eligibility for an experience rating is determined, your experience modification is calculated by comparing your actual losses to those you expected to incur. Actual losses: Medical/indemnity claim costs from work-related injuries that an insurance company has paid/will pay. Expected losses: Projected losses based on statistics within the industry in which a business operates, given classifications, payroll, and business size. Circumventing extremes While this process of predicting injury frequency is simple in theory; in practice, determining whether smaller businesses will actually experience an accident is difficult. This leads to less reliability and the possibility of over-inflated Minnesota workman's comp insurance costs due to an unreasonably high experience modification. Thus, compensating for this requires adjustments to modify the expected losses and actual losses for those businesses whose experience is not fully credible, in order to control experience modification volatility from year to year: Loss segregation Segregating the first $7,000 of losses for a claim as primary and the remaining amount above $7,000 as excess loss places weight on the primary portion – claim frequency – over total cost/severity. Primary/excess credibility adjustments Taken together, primary and excess credibility values represent the weight given in the experience rating formula to your business’ actual loss experience. Larger businesses have more weight (credibility) attributable to actual experience, whereas smaller businesses have less weight (credibility) given to their actual experience.
