When calculating workers' compensation rates, which factor has the greatest impact on premium costs?

Correct Answer

C) Experience modification factor (EMR)

The Experience Modification Rate (EMR) directly multiplies the base premium and can significantly increase or decrease costs based on the company's safety record compared to industry averages.

Answer Options
A
Company's annual revenue
B
Number of employees
C
Experience modification factor (EMR)
D
Geographic location of projects

Why This Is the Correct Answer

CORRECT_ANSWER - The Experience Modification Rate (EMR) is a multiplier that directly affects the workers' compensation premium calculation. An EMR above 1.0 increases premiums while below 1.0 decreases them, making it the most impactful factor. A company with a poor safety record could have an EMR of 1.5 or higher, increasing their premium by 50% or more, while a company with excellent safety could have an EMR of 0.7, reducing premiums by 30%.

Why the Other Options Are Wrong

Option A: Company's annual revenue

While annual revenue affects the overall cost through payroll exposure, it doesn't directly modify the rate calculation like EMR does. Revenue determines the base amount but EMR multiplies that base amount.

Option B: Number of employees

Number of employees affects total premium through increased payroll exposure, but the rate per $100 of payroll remains the same. EMR actually modifies the rate itself, making it more impactful.

Option D: Geographic location of projects

Geographic location does affect base rates due to regional differences in medical costs and claim frequencies, but these variations are typically modest compared to EMR impacts which can range from 0.5 to 2.0 or higher.

Memory Technique

Think 'EMR = Expensive Mistakes Remembered' - your past safety record (experience) modifies (multiplies) your rates more than any other single factor
