Which factors do EMR rating systems consider when calculating premiums?

• A. Average incident losses and payroll
• B. Equipment value and location
• C. Annual revenue and market share
• D. Employee satisfaction and training hours

Answer: (A)

Experience Modification Rate (EMR) uses past claim experience relative to exposure to set workers’ comp premiums. The key idea is to look at how costly and frequent a company’s past injuries were, relative to the size of its employee base. Average incident losses capture how severe and frequent those claims were, while payroll provides the exposure basis—normalizing losses to the number of workers and the amount of payroll at risk. Together, they reflect the risk the insurer expects to cover moving forward. That’s why this combination is the best fit: it directly ties past claim experience to the level of exposure, which is exactly what EMR hinges on when adjusting premiums. Other factors listed, like equipment value and location, relate more to property or general asset risk; annual revenue and market share are business performance metrics not used to gauge workers’ comp risk; and employee satisfaction or training hours don’t directly feed into EMR calculations, even though they can influence safety over time, they aren’t the inputs used to compute the rate.
